Description

Die Erfindung betrifft einen Geländer-Bausatz gemäß dem Oberbegriff des Patentanspruches 1. Geländer können unter Verwendung solcher Bausätze zusammengefügt werden, und zwar zur Absperrung und/oder Unfallsicherung, insbesondere im Bereich von Treppenflanken, Bodenflanken von Bauwerken oder dgl., wobei zur Erzielung eines sicheren Haltes auch für den Fall, daß wenigstens Teile des Geländers nur provisorisch während der Bautätigkeit bzw. als Behelfs-Geländer vorgesehen werden sollen, mindestens eine Befestigungsvorrichtung zur Lagesicherung wenigstens eines Geländer-Bausatzes vorgesehen ist.The invention relates to a railing kit according to the preamble of claim 1. Railings can be put together using such kits, specifically for blocking and / or accident prevention, in particular in the area of stair flanks, floor flanks of buildings or the like, whereby to achieve a safe Stop also in the event that at least parts of the railing are only to be provisionally provided during construction or as temporary railings, at least one fastening device is provided to secure the position of at least one railing kit.

Die Geländer-Bausätze bilden zweckmäßig ein Geländer-System, das mindestens einen Geländerpfosten enthält, der für seine bauwerkseitige Befestigung eine als Spanneinrichtung ausgebildete Befestigungsvorrichtung mit einem gegenüber dem Pfostenkörper bewegbaren Spannglied aufweist.The railing kits expediently form a railing system which contains at least one railing post which, for its fastening on the building side, has a fastening device which is designed as a tensioning device and has a tensioning element which can be moved relative to the post body.

An Bauwerken müssen während der Bautätigkeit bzw. bis zur Fertigstellung Sicherungen gegen Unfälle angebracht werden, wofür es z.B. im Bereich von Treppenflanken, frei ausragenden Böden, Balkonplatten oder dgl. zweckmäßig ist, ein provisorisches Geländer anzuordnen und abnehmbar auszubilden, so daß es, sobald das für das fertige Bauwerk bestimmte Geländer montiert werden kann oder keine gesonderte Sicherung mehr erforderlich ist, wieder entfernt werden kann.Safety devices against accidents must be attached to buildings during construction or until completion, for which it projects freely, for example in the area of stairs Floors, balcony slabs or the like. It is expedient to arrange a temporary railing and to make it removable, so that it can be removed again as soon as the railing intended for the finished building can be installed or no special securing is required.

Die DE-A 29 10 325 zeigt einen Geländerpfosten, an dem eine hakenförmige Aufnahmetasche für ein als Geländer-Längslauf dienendes Brett angebracht ist. An diesem Haken ist ein schwenkbarer Exzenter vorgesehen, mit dem das Brett in der Tasche gegen den Geländerpfosten festgeklemmt werden kann. Es liegt also eine reine kraftschlüssige Verbindung vor.DE-A 29 10 325 shows a railing post on which a hook-shaped receiving pocket for a board serving as a railing longitudinal run is attached. A pivotable eccentric is provided on this hook, with which the board can be clamped in the pocket against the railing post. So there is a pure frictional connection.

Durch die US-A-3 848 854 ist ein Geländerbausatz mit Längsläufen bekanntgeworden, die gegeneinander teleskopisch verstellbar und durch gesonderte Steckbügel verriegelbar sind, die in deckungsgleiche Stecköffnungen an den Oberkanten der Längsläufe sperrend so eingreifen, daß die Längsläufe nach unten herausfallen können. Dies kann nur durch gesonderte Holzkeile verhindert werden, ohne die die Teile auch zwangsläufig gegeneinander Bewegungsspiel hätten. Der Keil spannt zwar den äußeren Längslauf gegen ein Bauteil, nicht jedoch die Längsläufe unmittelbar gegeneinander, da diese Querspiel relativ zueinander habne. Steckbügel und Keil sind gesonderte, verlierbare Teile, die auf Baustellen schnell verschwinden.From US-A-3 848 854 a railing kit with longitudinal runs has become known, which are telescopically adjustable relative to one another and can be locked by separate plug-in brackets, which engage in congruent plug-in openings on the upper edges of the longitudinal runs so that the longitudinal runs can fall out downwards. This can only be prevented by using separate wooden wedges, without which the parts would inevitably have movement play against each other. The wedge tensions the outer longitudinal run against a component, but not the longitudinal runs directly against one another, since this has transverse play relative to one another. Plug-in bracket and wedge are separate, lost parts that quickly disappear on construction sites.

Aus der DE-A-29 37 234 ist ein Baugeländer bekanntgeworden, bei dem dübelartig in Hülsen befestigte Geländerpfosten mit Geländerlängsläufen aus Holz versehen werden, die jeweils ein Rundloch und ein Langloch aufweisen. Die somit an gewisse Längendifferenzen zwischen den Geländerpfosten anpaßbaren Längsläufe werden durch Schrauben an den Geländerpfosten befestigt, die durch die Löcher in den Längsläufen und entsprechende Löcher in den Geländerpfosten gesteckt und durch eine dahinter aufgeschraubte Mutter festgespannt werden. Die Befestigungsteile für die Längsläufe sind gesonderte, lose Teile.A construction railing has become known from DE-A-29 37 234, in which railing posts fastened in sleeves are provided with railing longitudinal rails made of wood, each having a round hole and an elongated hole. The longitudinal runs thus adaptable to certain differences in length between the railing posts are fastened to the railing posts by screws which pass through the holes in the longitudinal runs and Corresponding holes are inserted in the railing posts and tightened using a nut screwed behind them. The fastening parts for the longitudinal runs are separate, loose parts.

Durch die FR-A-2 595 741 ist ein Geländerpfosten bekanntgeworden, der zur bauwerksseitigen Befestigung eine Spannzange aufweist, welche vom oberen Ende des Geländerpfostens her über eine Spindel betätigbar ist. Durch die FR-A-2 417 608 ist ein Halter mit einem Innen-Spannglied bekanntgeworden, das durch Schrägflächen gegenüber einer Hülse verspannt werden kann, welche zuvor bauwerksseitig durch Einbetonieren festzulegen ist.From FR-A-2 595 741 a railing post has become known which has a collet for fastening on the building side, which can be actuated from the upper end of the railing post via a spindle. From FR-A-2 417 608 a holder with an inner tendon has become known, which can be braced by inclined surfaces with respect to a sleeve, which is to be fixed beforehand on the building side by concreting.

Aufgabe der Erfindung ist es, ein Geländer-System zu schaffen, welches die Nachteile bekannter Lösungen verhindert und insbesondere auch bei abnehmbarer Ausbildung eine leicht zu handhabende Lagesicherung sowie eine schnelle Montage und Demontage ermöglicht.The object of the invention is to provide a railing system which prevents the disadvantages of known solutions and, in particular even with a detachable design, enables easy-to-use position securing and quick assembly and disassembly.

Zur Lösung dieser Aufgabe dienen die Merkmale des Anspruchs 1. Es wird also ein Geländer mit Handlauf vorgeschlagen, das durch ein längenverstellbares Profil aus Metall oder dgl. gebildet ist und z.B. nach Art einer Teleskopstange in ihrer Länge an die jeweiligen Einbauverhältnisse angepaßt werden kann. Ihre Befestigungsvorrichtung ist als Spanneinrichtung dafür geeignet, die Geländerstange gegenüber dem oder den Gelängerpfosten spielfrei, jedoch lösbar, lagezusichern. Die einzelnen Bauteile dieser Spanneinrichtung sind unverlierbar am Geländerpfosten vorgesehen.The features of claim 1 serve to solve this problem. A railing with a handrail is therefore proposed, which is formed by a length-adjustable profile made of metal or the like and is e.g. can be adapted in length to the respective installation conditions in the manner of a telescopic rod. Your fastening device is suitable as a tensioning device for securing the railing rod relative to the railing post (s) without play, but releasably. The individual components of this tensioning device are captively provided on the railing post.

Für viele Anwendungszwecke ist es vorteilhaft, wenn an dem jeweiligen Geländerpfosten zusätzlich zur beschriebenen Befestigungsvorrichtung für die Geländerstange wenigstens eine Halterung vorgesehen ist, die mindestens einen bügelförmigen Trag-Griff, eine Längs-Steckaufnahme für ein von Durchbrechungen freies Leistenprofil oder dgl. bildet.For many applications, it is advantageous if at least on the respective railing post in addition to the described fastening device for the railing rod a holder is provided which forms at least one bow-shaped carrying handle, a longitudinal plug-in receptacle for a strip profile free of perforations or the like.

Zweckmäßig weist der Geländerpfosten dabei an seiner äußeren Außenseite, die von seinem Spannarm bzw. seinen Spannarmen abgekehrt liegt, mindestens einen Bügel auf, der mit den Enden seiner übereinanderliegenden Bügelschenkel an dieser Außenseite durch Schweißen oder dgl. befestigt ist. Ist ein Bügel unmittelbar benachbart zum oberen Ende und ein Bügel unmittelbar benachbart zur Oberseite der Befestigungsvorrichtung für die Bauwerksbefestigung vorgesehen, so können Abschrankungsleisten sowohl in verhältnismäßig großer Höhe als auch nahe dem Boden- bzw. Trittniveau lediglich durch Einschieben an benachbarten Geländerpfosten gehaltert werden. Die Befestigungsvorrichtung zur Bauwerksbefestigung und die Befestigungsvorrichtung für die Geländerstangen liegen zweckmäßig an derselben, inneren Außenseite des Geländerpfostens.The railing post expediently has on its outer outside, which is remote from its clamping arm or its clamping arms, at least one bracket, which is fastened to the outside by welding or the like with the ends of its superimposed bracket legs. If a bracket is provided directly adjacent to the upper end and a bracket is located directly adjacent to the top of the fastening device for the structural fastening, then the barrier strips can be held both at a relatively high height and near the floor or step level simply by pushing them into adjacent railing posts. The fastening device for fastening the structure and the fastening device for the railing rods are expediently located on the same inner outside of the railing post.

Gemäß einem bevorzugten Merkmal der Erfindung wird des weiteren eine lösbare Verbindung der einander zugekehrten Enden von Geländerstangen vorgeschlagen, die in Längsrichtung aneinander entweder miteinander fluchtend oder, z.B. im Winkel, gegeneinander versetzt anschließen. Zweckmäßig ist diese Verbindung so ausgebildet, daß die aneinanderschließenden Geländerstangen sowohl fluchtend als auch in mindestens einer Winkellage miteinander verbunden werden können, wobei zweckmäßig die Verbindung nach Art einer Gelenkverbindung eine stufenlose Winkelverstellung ermöglicht. Dadurch können z.B. Geländer mit Geländerstangen geschaffen werden, die entsprechend dem Verlauf von Treppenabschnitten und Zwischenpodesten abgewinkelt verlaufende Geländerstnagen aufweisen.According to a preferred feature of the invention, a releasable connection of the mutually facing ends of railing rods is also proposed, which connect to one another in the longitudinal direction either in alignment or, for example at an angle, offset with respect to one another. This connection is expediently designed in such a way that the adjoining railing rods can be connected to one another both in alignment and in at least one angular position, the connection in the manner of an articulated connection expediently allowing a stepless angle adjustment. This allows, for example, railings to be created with railing rods that have railing rods that run at an angle in accordance with the course of stair sections and intermediate platforms.

Bei einem Geländer der beschriebenen Art können erfindungsgemäß auch Mittel vorgesehen sein, um einen bzw. mehrere Geländerpfosten über eine Stelleinrichtung in ihrer Einbaulage so verspannen zu können, daß das Spannmoment feinfühlig und genau bestimmt werden kann. Ist die Stelleinrichtung als im wesentlichen Ganzes am Geländerpfosten permanent gelagert, so ergibt sich eine unverlierbare Ausbildung sämtlicher Teile der Spanneinrichtung. Des weiteren ermöglicht es die Verwendung einer Stelleinrichtung, das Betätigungsglied verhältnismäßig weit entfernt vom eigentlichen Spannbereich des Geländerpfostens bzw. an einer solchen Stelle vorzusehen, an welcher es zur Betätigung besonders gut zugänglich ist. Diese Stelle kann an der vom Spannbereich abgekehrten Seite des Geländerpfostens und/oder in Höhenrichtung gegenüber dem Spannbereich versetzt liegen und nimmt praktisch bei jeder Betätigungsstellung dieselbe Lage gegenüber dem Geländerpfosten bzw. dem Pfostenkörper ein, vorzugsweise am oberen Ende des Geländerpfostens.In the case of a railing of the type described, means can also be provided according to the invention in order to be able to clamp one or more railing posts in their installed position via an adjusting device in such a way that the tensioning torque can be determined sensitively and precisely. If the actuating device as a whole is permanently stored on the railing post, all parts of the tensioning device are designed to be captive. Furthermore, the use of an actuating device makes it possible to provide the actuating member relatively far away from the actual clamping area of the railing post or at such a location at which it is particularly easily accessible for actuation. This point can be offset on the side of the railing post facing away from the tensioning area and / or in the vertical direction with respect to the tensioning area and takes up practically the same position in relation to the railing post or the post body in every actuation position, preferably at the upper end of the railing post.

Durch die erfindungsgemäße Ausbildung kann des weiteren das Betätigungsglied so ausgebildet sein, daß es durch Drehen zu betätigen ist, so daß z.B. mit einem Drehmomentschlüssel das Anzugsmoment der Spanneinrichtung genau festgelegt werden kann. Sollen hierbei die Betätigungskräfte deutlich niedriger als die Spannkräfte liegen, so kann zwischen dem Betätigungsglied und dem Spannglied ein Untersetzungstrieb vorgesehen sein, der z.B. durch einen Spindeltrieb und/oder einen Lenkertrieb und/oder eine Keiluntersetzung o.dgl. gebildet sowie ein- oder mehrstufig ausgebildet sein kann.Due to the design according to the invention, the actuator can also be designed so that it can be operated by turning, so that e.g. the tightening torque of the clamping device can be precisely determined with a torque wrench. If the actuating forces are to be significantly lower than the clamping forces, a reduction gear can be provided between the actuating element and the clamping element, e.g. by a spindle drive and / or a handlebar drive and / or a wedge reduction or the like. formed and can be formed in one or more stages.

Die erfindungsgemäße Ausbildung eignet sich zur Außenspannung, bei welcher z.B. der Geländerpfosten eine Art Spannzwinge aufweist, deren Zangenarme zur Verspannung einander angenähert werden und dadurch z.B. von oben und unten gegen eine Treppe oder beiderseits seitlich gegen die Seitenflächen einer Mauer verspannt werden können.The design according to the invention is suitable for external tension, in which e.g. the railing post has a type of clamp, the gripper arms of which are brought closer together for bracing and thereby e.g. can be braced from above and below against a staircase or on both sides laterally against the side surfaces of a wall.

Eine besonders vorteilhafte Weiterbildung ergibt sich jedoch auch, wenn die Spanneinrichtung stattdessen oder zusätzlich hierzu zur Innenspannung ausgebildet ist, so daß sie z.B. nach Art einer wenigstens teilweise aufweitbaren Innen-Spannzange gegen die Innenflächen einer bauwerksseitigen Öffnung verspannt werden kann. Die Spannzange kann eine zapfenartige Fortsetzung des unteren Endes des Geländerpfostens bilden oder, je nach den bauwerkseitigen Erfordernissen, nach Art eines Winkelschenkels quer vom Geländerpfosten abstehen.A particularly advantageous further development also results if the tensioning device is designed instead or in addition to the internal tensioning, so that it e.g. can be clamped in the manner of an at least partially expandable inner collet against the inner surfaces of an opening on the building side. The collet can form a peg-like continuation of the lower end of the railing post or, depending on the structural requirements, project transversely from the railing post in the manner of an angle leg.

Damit am Bauwerk ungehindert Arbeiten ausgeführt werden können, die seitlich über eine dem jeweiligen Geländerpfosten zugeordnete bzw. gegenüberliegende Bauwerksbegrenzung hinausreichen, ist es besonders vorteilhaft, wenn Mittel vorgesehen sind, die es ermöglichen, den Geländerpfosten in einem entsprechenden Abstand von dieser Bauwerksbegrenzung anzuordnen. Dadurch können diese Arbeiten ohne vorherige Entfernung des Behelfs-Geländers ausgeführt werden. Zum Beispiel müssen beim Bau einer Treppe häufig abschließend noch Trittplatten verlegt werden, die seitlich an der dem Geländer zugehörigen Seite über die zugehörige Begrenzung des zum Beispiel aus Beton bestehenden, vor Anbringung des Geländers hergestellten Treppenkörpers hinausreichen. Insbesondere, wenn die Befestigungsvorrichtung zur Innenspannung derart ausgebildet ist, daß das Behelfs-Geländer keinerlei im Bereich der Trittflächen der Stufen liegende Bauteile aufweist, kann der jeweilige Geländerpfosten durch diese Mittel so im Abstand von der zugehörigen, in einer vertikalen Ebene liegenden seitlichen Begrenzung der Trittfläche der jeweiligen Treppenstufe angeordnet werden, daß in deren Ebene auch über die Flächenbegrenzung hinaus keinerlei Bauteile des Geländers liegen, sondern Freiraum für die Anbringung von Bauwerkteilen gegeben ist. Besonders vorteilhaft ist es, wenn der Abstand zwischen etwa 40 und 100 mm, vorzugsweise bei mindestens etwa 70 mm liegt.So that work can be carried out on the building unhindered, which extends laterally beyond a building boundary assigned or opposite the respective railing post, it is particularly advantageous if means are provided which enable the railing post to be arranged at a corresponding distance from this building boundary. This allows this work to be done without prior removal of the temporary railing. For example, when building a staircase, step plates must often be installed that extend laterally on the side belonging to the railing beyond the associated limitation of the stairway body, which is made of concrete, for example, before the railing was attached. In particular, if the fastening device for the internal tension is designed such that the makeshift railing has no components in the area of the treads of the steps, the respective railing post can be spaced apart from the associated lateral boundary of the tread surface by these means be arranged at the respective stair step in such a way that there are no components of the railing beyond the area delimitation, but that there is free space for the attachment of structural parts. It is particularly advantageous if the distance is between approximately 40 and 100 mm, preferably at least approximately 70 mm.

Eine besonders vorteilhafte Weiterbildung des Erfindungsgegenstandes besteht darin, daß die Spanneinrichtung und/oder die Stelleinrichtung im wesentlichen innerhalb des wenigstens teilweise hohlen Geländerpfostens angeordnet ist, der somit unmittelbar mit seiner Wandung ein Gehäuse für die geschützte Aufnahme der entsprechenden Bauteile bildet. Die Führung des verstellbaren Spanngliedes gegenüber dem Pfostenkörper kann ebenfalls im wesentlichen geschützt innerhalb des Pfostenkörpers z.B. dadurch liegen, daß eine Teleskopführung vorgesehen ist, von der zweckmäßig der Teleskop-Außenteil durch den rohrförmigen Pfostenkörper gebildet ist.A particularly advantageous development of the subject matter of the invention is that the tensioning device and / or the actuating device is arranged essentially within the at least partially hollow railing post, which thus directly forms with its wall a housing for the protected accommodation of the corresponding components. The guidance of the adjustable tendon relative to the post body can also be substantially protected within the post body e.g. characterized in that a telescopic guide is provided, of which the telescopic outer part is expediently formed by the tubular post body.

Die der Erfindung zugrundeliegende Aufgabe läßt sich bei einem Geländer der beschriebenen oder einer anderen Art in vorteilhafter Weise auch dadurch lösen, daß mindestens eine Spannfläche wenigstens eines Spanngliedes in mindestens einer von der Spannbewegung unabhängigen Bewegung verstellbar ist, so daß z.B. die Neigungen zweier einander gegenüberliegender bzw. voneinander abgekehrter Spannflächen gegenseitig zur Anpassung an entsprechend geneigte Flächen des Bauwerkes verändert werden können.The object on which the invention is based can advantageously be achieved in a railing of the type described or another type in that at least one clamping surface of at least one tendon in at least one a movement that is independent of the tensioning movement is adjustable, so that, for example, the inclinations of two opposing or facing clamping surfaces can be mutually changed to adapt to correspondingly inclined surfaces of the building.

Um auch bei Vorhandensein relativ großer Unebenheiten eine möglichst spielfreie Anlage von Spannflächen der Befestigungsvorrichtung eines Geländerpfostens zu gewährleisten, sind vorteilhaft Mittel vorgesehen, die durch gegenüber dem jeweiligen gesamten Spannfeld kleinere Spannflächen und/oder durch geringfügig elastische Nachgiebigkeit dieser Spannflächen eine spielfreie Anpassung an solche Unebenheiten o.dgl. gewährleisten. Zum Beispiel kann jede Spannfläche durch zwei parallel nebeneinanderliegende, zum Geländerpfosten annähernd rechtwinklige Spannflächen-Bereiche gebildet sein. Auch können einzelne Spannflächen-Bereiche gegeneinander und/oder gegenüber dem Geländerpfosten innerhalb geringer Grenzen und unter sehr hoher Federkraft federnd lageveränderbar sein. Bei einer bevorzugten Ausführungsform sind die Spannflächen-Bereiche des jeweiligen Spannarmes an Kanten eines im Querschnitt von der ebenen Form abweichenden Profiles vorgesehen bzw. durch dieses gebildet, wobei das Profil zweckmäßig angenähert rechtwinklig bis stumpfwinklig V-förmig mit gleich langen Profilschenkeln ausgebildet ist. Sind an beiden einander gegenüberliegenden Spannarmen jeweils im Abstand zueinander liegende Spannflächen-Bereiche vorgesehen, so können diese an beiden Spannarmen unterschiedliche oder gleiche Abstände voneinander haben und insbesondere so angeordnet sein, daß sich in Richtung der Spannkraft jeweils zwei Spannflächen-Bereiche unmittelbar gegenüberliegen. Das in sich geringfügig federnd nachgiebige V-Profil gewährleistet eine sehr steil ansteigende Federkennlinie.In order to ensure that the tensioning surfaces of the fastening device of a railing post are as free of play as possible, even in the presence of relatively large unevenness, means are advantageously provided which, due to smaller tensioning surfaces compared to the respective entire tensioning field and / or slightly elastic compliance of these tensioning surfaces, enable a play-free adaptation to such unevenness o . Like. guarantee. For example, each clamping surface can be formed by two clamping surface areas lying parallel to one another and approximately at right angles to the railing post. Individual clamping surface areas can also be resiliently changeable in relation to one another and / or with respect to the railing post within small limits and under very high spring force. In a preferred embodiment, the clamping surface areas of the respective clamping arm are provided on edges of a profile which deviates from the planar shape in cross section, the profile advantageously being approximately rectangular to obtuse V-shaped with profile legs of equal length. If the clamping surface areas are spaced apart from each other on the two opposing clamping arms, they can be at different or equal distances from each other on the two clamping arms and in particular be arranged such that two clamping surface areas are located directly opposite each other in the direction of the clamping force. The slightly resilient V-profile ensures a very steep spring characteristic.

Eine andere zweckmäßige Ausbildung des Erfindungsgegenstandes besteht darin, daß der jeweilige Spannarm mit seinem vom freien Ende abgekehrten inneren Ende an einer Endfläche eines stabförmigen Bauteiles des Geländerpfostens, z.B. des Teleskop-Außenrohres bzw. des Teleskop-Innenrohres so befestigt ist, daß er mit seiner inneren Endfläche im wesentlichen bündig mit der von seinem freien Ende abgekehrten Außenseite dieses Bauteiles abschließt und dabei in Seitenansicht über seine Länge durchgehend geradlinig ist. Die Endfläche des stabförmigen Bauteiles ist vorteilhaft entsprechend der Eingriffsfläche des Profiles, z.B. V-förmig profiliert, so daß sich eine vollflächige Anlage ergibt, die jedoch nicht über die gesamte Profilhöhe des Profilarmes reichen muß, insbesondere wenn dessen Spannflächen-Bereiche einen seitlichen Abstand voneinander haben, der größer als die zugehörige Außenweite des stabförmigen Bauteiles des Geländerpfostens ist. Im Falle der Befestigung des Profiles an der Endfläche des Teleskop-Außenrohres weist das Profil zweckmäßig eine Durchgangsöffnung für das Teleskop-Innenrohr auf, so daß es von diesem durchsetzt wird, jedoch trotzdem über den gesamten Wandungsumfang des Außenrohres mit diesem durch Schweißnähte verbunden sein kann.Another expedient embodiment of the subject matter of the invention is that the respective tension arm with its inner end facing away from the free end on an end face of a rod-shaped component of the railing post, e.g. of the telescopic outer tube or of the telescopic inner tube is fastened in such a way that its inner end surface is essentially flush with the outside of this component facing away from its free end and is continuously linear in its side view over its length. The end surface of the rod-shaped component is advantageously corresponding to the engagement surface of the profile, e.g. Profiled in a V-shape, so that there is a full-surface contact, which, however, does not have to extend over the entire profile height of the profile arm, in particular if its clamping surface regions have a lateral distance from one another which is greater than the associated outer width of the rod-shaped component of the railing post. In the case of attachment of the profile to the end face of the telescopic outer tube, the profile expediently has a through opening for the telescopic inner tube so that it is penetrated by it, but can nevertheless be connected to the outer tube with weld seams over the entire circumference of the wall.

In weiterer Ausgestaltung der Erfindung sind, insbesondere bei einem Geländerpfosten, der mit mindestens einem quer abstehenden Arm zu befestigen ist, Mittel vorgesehen, damit die einspringende Ecke zwischen diesem Arm und dem Geländerpfosten wenigstens an der Oberseite des Armes oder über dessen gesamten Umfang von Bauteilen, wie z.B. von Versteifungs-Verstrebungen, völlig frei ist. Im Falle einer Außenspannung können solche Verstrebungen am oberen Spannarm zu Unfallgefahren durch Stolpern von Personen führen, während sie im Falle einer Innenspannung über die zugehörige Außenseite des Geländerpfostens höchstens nur um ein Maß vorstehen sollten, das dem beschriebenen Abstandsmaß entspricht, damit der Spannzapfen ungehindert tief genug in das Bauwerk versenkt werden kann. Damit auf solche Versteifungsmittel verzichtet werden kann, wird der Spannarm z.B. als Profilarm so laststeif ausgebildet, daß er unter den beim Spannen auftretenden Belastungen nicht oder nur unwesentlich nachgibt.In a further embodiment of the invention, in particular in the case of a railing post which is to be fastened with at least one arm projecting transversely, means are provided so that the protruding corner between this arm and the railing post at least on the upper side of the arm or over its entire circumference of components, such as stiffening struts, is completely free. In the event of an external tension, such struts on the upper tension arm can lead to accident hazards due to stumbling of people, while in the case of internal tension they should at most only protrude beyond the associated outside of the railing post by an amount that corresponds to the distance described, so that the tension pin is deep enough without hindrance into the building can be sunk. So that such stiffening means can be dispensed with, the tensioning arm, for example as a profile arm, is designed to be so stiff that it does not yield, or only insignificantly, yields under the loads occurring during tensioning.

Des weiteren läßt sich die der Erfindung zugrundeliegende Aufgabe bei einem Geländer der beschriebenen oder einer anderen Art in vorteilhafter Weise dadurch lösen, daß mindestens ein vom Geländer bzw. vom Geländerpfosten gesondertes Gegenglied für die Aufnahme der Befestigungsvorrichtung vorgesehen ist, das z.B. vor Anbringung des Geländers an der entsprechenden Stelle des Bauwerkes durch Einbetonieren festgelegt werden kann. Dieses Gegenglied kann so ausgebildet sein, daß es sowohl für die Aufnahme des provisorischen Geländers als auch, nach dessen Entfernung, für die Befestigung des endgültig am Bauwerk anzubringenden Geländers o.dgl. geeignet ist.Furthermore, the object on which the invention is based can be achieved in an advantageous manner in a railing of the type described or in another type by providing at least one counter-member separate from the railing or the railing post for receiving the fastening device, which e.g. can be set in concrete at the appropriate place on the structure before attaching the railing. This counter member can be designed so that it or the like both for receiving the provisional railing and, after its removal, for fastening the railing to be finally attached to the structure. suitable is.

Das Gegenglied ist, insbesondere im Falle einer Innenspannung, zweckmäßig als Aufnahme-Hülse aus Stahl, Kunststoff oder einem ähnlich geeigneten Werkstoff ausgebildet. Diese Hülse weist im inneren und/oder an ihrem äußeren Ende, z.B. an einer mit ihr verbundenen und über ihren Außenumfang vorstehenden Flanschplatte, Anschlußflächen, wie Schweißflächen zur lagestarren Verbindung mit einem Geländerpfosten auf. Wenigsten ein Teil dieser Anschlußflächen, die zweckmäßig durch Innenflächen des Hülsenmantels gebildet sind, sind wahlweise auch für eine lösbare Verbindung mit dem Geländerpfosten, vorzugsweise als im wesentlichen ebene bzw. im Längsschnitt durch die Hülse ununterbrochen im wesentlichen geradlinige Klemmflächen ausgebildet.The counterpart, particularly in the case of internal tension, is expediently designed as a receiving sleeve made of steel, plastic or a similarly suitable material. This sleeve has in the inner and / or at its outer end, e.g. on a flange plate connected to it and projecting beyond its outer circumference, connection surfaces, such as welding surfaces, for rigid connection to a railing post. At least a part of these connection surfaces, which are expediently formed by inner surfaces of the sleeve shell, are optionally also designed for a releasable connection to the railing post, preferably as a substantially flat or in longitudinal section through the sleeve, essentially straight clamping surfaces.

Damit der Geländerpfosten insbesondere seitlich gegenüber dem Bauwerk genau justiert und dann in jeder beliebigen Justierlage gleich gut spielfrei lagegesichert werden kann, ist es vorteilhaft, wenn die Verbindung zwischen dem Behelfs-Geländerpfosten und der Aufnahme-Hülse ausschließlich kraftschlüssig erfolgt. Vorteilhaft ist der Hülsenmantel der Aufnahme-Hülse im wesentlichen über seine Länge bzw. über seinen Umfang von Durchbrüchen frei, so daß sich annähernd über die gesamte Länge des Hülsenmantels kontinuierliche Klemmflächen ergeben. Statt dessen oder zusätzlich hierzu kann am inneren Ende des, z.B. durch einen Rohrabschnitt gebildeten, Hülsenmantels ein abdichtender Deckel aus einen anderen geeigneten Werkstoff, z.B. Kunststoff, befestigt sein, durch den ein Eindringen von Beton in den Hülsenmantel vollständig ausgeschlossen werden kann. Dieser Deckel läßt sich in besonders einfacher Weise durch eine zum Hülsenmantel parallele Steckverbindung befestigen und lagesichern, wobei der Deckel auf den Außenumfang des Hülsenmantels aufgesteckt oder in diesen so eingesteckt sein kann, daß der Deckel über den Außenumfang des Hülsenmantels nicht vorsteht.So that the railing post can be precisely adjusted, in particular laterally with respect to the building, and can then be secured with no play in any adjustment position, it is advantageous if the connection between the temporary railing post and the receiving sleeve is only non-positively. Advantageously, the sleeve shell of the receiving sleeve is substantially free of breakthroughs over its length or over its circumference, so that continuous clamping surfaces result approximately over the entire length of the sleeve shell. Instead of or in addition to this, a sealing cover made of another suitable material, for example plastic, can be attached to the inner end of the sleeve shell, for example formed by a tube section, through which penetration of concrete into the sleeve shell can be completely ruled out. This cover can be attached and secured in a particularly simple manner by means of a plug connection parallel to the sleeve casing, the cover being placed on the outer circumference of the sleeve casing or being inserted into it such that the cover does not protrude beyond the outer circumference of the sleeve casing.

Das Geländer 1 gemäß Fig. 1 kann z.B. aus einem mehrteiligen Bausatz zusammengesetzt werden, der eine Mehrzahl annähernd gleicher Geländerpfosten 2 und Geländer-Längsläufe, nämlich Geländerstangen 3 aufweist, die nach der bauwerkseitigen Montage der Geländerpfosten 2 an diesen lösbar zu befestigen sind. Zur Befestigung am Bauwerk weist jeder Geländerpfosten 2 z.B. im Bereich seines unteren Endes eine zweckmäßig im wesentlichen vertikal spannende Befestigungsvorrichtung 4 auf, während zur Befestigung der Geländerstange 3 am jeweiligen Geländerpfosten 2 Spannmittel vorgesehen sind, nämlich jeweils eine Befestigungsvorrichtung 5.The railing 1 according to Fig. 1 can e.g. be assembled from a multi-part kit, which has a plurality of approximately the same railing posts 2 and railing longitudinal runs, namely railing rods 3, which are releasably attached to the post 2 after assembly on the building. Each railing post 2 has e.g. in the region of its lower end there is an expediently essentially vertically tensioning fastening device 4, while 2 fastening means are provided for fastening the railing rod 3 to the respective railing post, namely one fastening device 5 each.

Der jeweilige Geländerpfosten 2 weist einen über den größten Teil seiner Länge bzw. Höhe sowie im wesentlichen bis zu seinem oberen Ende reichenden, hohlen Pfostenkörper 6 auf, der zweckmäßig durch einen Abschnitt eines Profilrohres, wie eines quadratischen Vierkantrohres gebildet ist. Im Bereich des unteren Endes ist an dem Pfostenkörper 6 eine zu diesem parallele Teleskopführung 7 vorgesehen, deren Außenrohr durch den unteren Endabschnitt des Pfostenkörpers 6 gebildet ist und dessen Teleskop-Innenstange 8 aus dem unteren Ende des Pfostenkörpers 6 vorsteht. Die Innenstange 8 ist zweckmäßig ebenfalls durch ein Profilrohr gebildet, dessen Querschnitte gleiche Grundform wie das Außenrohr aufweisen.The respective railing post 2 has a hollow post body 6 that extends over most of its length or height and essentially up to its upper end, which is expediently formed by a section of a profiled tube, such as a square square tube. In the region of the lower end, a telescopic guide 7 is provided on the post body 6, the outer tube of which is formed by the lower end section of the post body 6 and the telescopic inner rod 8 protrudes from the lower end of the post body 6. The inner rod 8 is also expediently formed by a profile tube, the cross sections of which have the same basic shape as the outer tube.

Die Befestigungsvorrichtung 4 ist im wesentlichen als Spannzwinge 9 ausgebildet, die mit einer im wesentlichen innerhalb des Pfostenkörpers 6 bzw. der Teleskopführung 7 liegenden Stelleinrichtung 10 über ihren gesamten Stellweg mit Hilfe eines einzigen Betätigungsgliedes 11 zu schließen bzw. zu öffnen ist. Die Stelleinrichtung 10 weist eine vom oberen Ende des Pfostenkörpers 6 im wesentlichen frei nach unten ragende, in der Achse des Pfostenkörpers 6 liegende Gewinde-Spindel 12 auf, die in eine am oberen Ende der Innenstange 8 befestigte Spindelmutter 13 so eingreift, daß ein Teil ihrer Länge innerhalb der Innenstange 8 liegt. Das obere Ende der Spindel 12 ist mit einem innerhalb des oberen Endes des Pfostenkörpers 6 liegenden Axiallager 14 so gelagert, daß die Spindel 12 einschließlich des Betätigungsgliedes 11 in beiden entgegengesetzten Richtungen gegenüber dem Pfostenkörper 6 axial lagegesichert ist. Zu diesem Zweck ist in eine obere Endplatte des Pfostenkörpers 6 eine Lagerbuchse 15 eingesetzt, die mit einem oberen Ringbund an der Oberseite der Endplatte anliegt und deren unterer Stirnseite ein am Außenumfang der Spindel 12 befestigter Lagerring 16 oder ein ähnliches Axialsicherungsglied gegenüberliegt. Das obere Ende der Spindel 12 geht in das im Querschnitt erweiterte Betätigungsglied 11 über, das mit seiner zugehörigen Stirnfläche am Bund der Lagerbuchse 15 axial gesichert anliegt. Das Betätigungsglied 11 ist im dargestellten Ausführungsbeispiel durch einen in der Achse der Spindel 12 liegenden Außensechskant gebildet.The fastening device 4 is essentially designed as a clamp 9, which, with an actuating device 10 lying essentially within the post body 6 or the telescopic guide 7, extends over its entire travel range With the help of a single actuator 11 to close or open. The actuating device 10 has a substantially freely downwardly projecting from the upper end of the post body 6, lying in the axis of the post body 6, threaded spindle 12 which engages in a spindle nut 13 fastened to the upper end of the inner rod 8 so that part of it Length is within the inner rod 8. The upper end of the spindle 12 is mounted with an axial bearing 14 located within the upper end of the post body 6 in such a way that the spindle 12, including the actuating member 11, is axially secured to the post body 6 in both opposite directions. For this purpose, a bearing bush 15 is inserted into an upper end plate of the post body 6, which lies with an upper ring collar on the upper side of the end plate and whose lower end face is opposite a bearing ring 16 fastened to the outer circumference of the spindle 12 or a similar axial securing member. The upper end of the spindle 12 merges into the actuating member 11, which has an enlarged cross section and which, with its associated end face, lies axially secured on the collar of the bearing bush 15. In the exemplary embodiment shown, the actuator 11 is formed by an external hexagon lying in the axis of the spindle 12.

Die Spannzwinge 9 weist ein gegenüber dem Pfostenkörper 6 in Spannrichtung bewegbares, unteres Spannglied 17 sowie eine diesem darüber gegenüberliegende Spannbacke 18 auf, welche gegenüber dem Pfostenkörper 6 lagestarr angeordnet ist. Die Spannzwinge 9 dient zur Verspannung gegenüber der Unter- und Oberseite eines strichpunktiert angedeuteten Bauwerkteiles 19, das z.B. durch eine Treppe, eine Bodenplatte o.dgl. gebildet sein kann. Der Spindeltrieb bildet beim Spannen und Lösen einen Untersetzungstrieb 20, so daß hohe Spannkräfte mühelos aufgebracht werden können.The clamping clamp 9 has a lower clamping member 17, which is movable in the clamping direction with respect to the post body 6, and a clamping jaw 18 opposite it, which is arranged in a rigid position relative to the post body 6. The clamp 9 is used to brace against the bottom and top of a dash-dotted building part 19, for example, by stairs, a floor slab or the like. can be formed. The spindle drive forms a reduction drive 20 during tensioning and loosening, so that high tensioning forces can be applied effortlessly.

Zur Bildung des Spanngliedes 17 ist im Bereich des unteren Endes an einer Außenseite der Innenstange 8 ein Querarm 21 so befestigt, daß er im wesentlichen symmetrisch zur Mittelebene dieser Außenseite und rechtwinklig zum Pfostenkörper 6 liegt. Der Querarm 21 ist zweckmäßig durch einen Rohrabschnitt mit rechteckigen Querschnitten gebildet, deren größere Kantenlänge etwa parallel zum Pfostenkörper 6 liegt und dessen Seitenflächen annähernd mit den zugehörigen Seitenflächen der Innenstange 8 fluchten. Zur Bildung der Spannbacke 18 ist an der gleichen Außenseite, jedoch am Pfostenkörper 6, mit geringem Abstand oberhalb von dessen unterem Ende ein plattenförmiger Querschenkel 22 befestigt, dessen Schenkelbreite zweckmäßig wesentlich größer als die des Querarmes 21 bzw. als die Außenweite des Pfostenkörpers 6 ist, so daß der Querschenkel 22 beiderseits seitlich über den Pfostenkörper 6 vorsteht. Der Querschenkel 22 kann durch einen Winkelschenkel einer Winkelplatte gebildet sein, die mit ihrem anderen, nach oben ragenden Winkelschenkel an der zugehörigen Außenseite des Pfostenkörpers 6 befestigt ist und deren Schenkel gegeneinander verstrebt sind. Die dem Spannglied 17 zugekehrte Fläche des Querschenkels 22 bildet die zugehörige, im wesentlichen ebene Spannfläche 24, die auch in Schenkellängsrichtung des Querschenkels 22 über das Spannglied 17 vorstehen kann, so daß sie eine Art Standfläche bildet, die selbst bei nicht geschlossener Spannzwinge 9 einen sicheren Stand des Geländerpfostens 2 auf dem Bauwerkteil 19 z.B. zum Zwecke der Ausrichtung gewährleistet.To form the tendon 17, a cross arm 21 is fastened in the region of the lower end on an outer side of the inner rod 8 in such a way that it lies essentially symmetrically to the central plane of this outer side and at right angles to the post body 6. The cross arm 21 is expediently formed by a tube section with rectangular cross sections, the greater edge length of which is approximately parallel to the post body 6 and whose side faces are approximately aligned with the associated side faces of the inner rod 8. To form the clamping jaw 18, a plate-shaped cross leg 22 is fastened on the same outside, but on the post body 6, at a short distance above its lower end, the leg width of which is expediently substantially larger than that of the cross arm 21 or as the outer width of the post body 6, so that the cross leg 22 protrudes laterally beyond the post body 6 on both sides. The cross leg 22 can be formed by an angle leg of an angle plate, which is attached with its other, upwardly protruding angle leg to the associated outside of the post body 6 and whose legs are braced against each other. The face of the cross member 22 facing the tendon 17 forms the associated, essentially flat clamping surface 24, which can also protrude in the longitudinal direction of the cross leg 22 over the tendon 17, so that it forms a kind of standing surface, which is secure even when the clamp 9 is not closed Stand of the railing post 2 on the building part 19, for example guaranteed for the purpose of alignment.

Die Spannfläche 23 des Spanngliedes 17 weist eine wesentlich kleinere Gesamtfläche als die Spannfläche 24 auf und ist zweckmäßig in mindestens zwei Einzelflächen unterteilt, von denen jede an einem Druckstück 25 im Abstand oberhalb des Querarmes 21 vorgesehen ist. Jede Einzelfläche der Spannfläche 23 ist durch den T-Quersteg eines T-förmigen Druckstückes 25 gebildet, das mit dem unteren Ende seines T-Fußsteges in einem Lager 26 des Querarmes 21 frei schwenkbar gelagert ist. Die Lagerachsen der Druckstücke 25 liegen zweckmäßig parallel bzw. fluchtend zueinander und rechtwinklig zum Pfostenkörper 6 bzw. parallel zum Querarm 21 in einer Axialebene des Pfostenkörpers 6 bzw. des Querarmes 21. Die gabelförmigen Lager 26 sind an der Oberseite des Querarmes 21 befestigt und weisen jeweils zwei beiderseits des zugehörigen Druckstückes 25 liegende Lagerwangen auf, wobei eine Lagerwange eines Lagers 26 gleichzeitig eine äußere Endplatte des Querarmes 21 bilden kann. Die beiden Druckstücke 25 liegen in Längsrichtung des Querarmes 21 im Abstand voneinander.The clamping surface 23 of the clamping member 17 has a substantially smaller total area than the clamping surface 24 and is expediently divided into at least two individual surfaces, each of which is provided on a pressure piece 25 at a distance above the cross arm 21. Each individual surface of the clamping surface 23 is formed by the T-crosspiece of a T-shaped pressure piece 25, which with the lower end of its T-footpiece is pivoted freely in a bearing 26 of the cross arm 21. The bearing axes of the pressure pieces 25 are expediently parallel or in alignment with one another and at right angles to the post body 6 or parallel to the cross arm 21 in an axial plane of the post body 6 or the cross arm 21. The fork-shaped bearings 26 are fastened to the top of the cross arm 21 and each have two bearing cheeks lying on both sides of the associated pressure piece 25, wherein a bearing cheek of a bearing 26 can simultaneously form an outer end plate of the cross arm 21. The two pressure pieces 25 are spaced apart in the longitudinal direction of the cross arm 21.

Zur Montage des Geländerpfostens 2 wird dieser bei geöffneter Befestigungsvorrichtung 4 etwa horizontal auf den Bauwerkteil 19 gesteckt, bis diejenige Außenseite des Pfostenkörpers 6, über welche die Spannarme der Spannzwinge 9 vorstehen, an der zugehörigen Kante des Bauwerkteiles 19 anschlägt. Insofern bildet das untere, unterhalb der Spannfläche 24 liegende Ende des Pfostenkörpers 6 einen Anschlag 27, durch welchen eine Berührung des Bauwerkteiles 19 durch die Innenstange 8 verhindert ist. Dann wird mit Hilfe eines Schraubenschlüssels das Betätigungsglied 11 gedreht, wodurch die unteren Spannflächen 23 gegenüber dem Pfostenkörper 6 angehoben werden, ohne daß der Pfostenkörper 6 selbst gegenüber dem Bauwerkteil 9 noch eine vertikale Bewegung auszuführen braucht. Die Spannzwinge 9 wird dann mit einem vorgegebenen Moment gegenüber dem Bauwerkteil 19 verspannt. Spätestens danach, gegebenenfalls aber auch bereits vor der endgültigen Verspannung gegenüber dem Bauwerkteil 19, wird mindestens eine Geländerstange 3 mit der Befestigungsvorrichtung 5 an derjenigen Außenseite des Pfostenkörpers 6 befestigt, über welche auch die Spannzwinge 9 vorsteht. Zweckmäßig sind zwei oder drei im Abstand übereinanderliegende Befestigungsvorrichtungen 5 bzw. Geländerstangen 3 vorgesehen, von denen die oberste über das obere Ende des Pfostenkörpers 6 und ggf. des Betätigungsgliedes 11 vorsteht und einen Handlauf bildet.To assemble the railing post 2, it is plugged approximately horizontally onto the building part 19 when the fastening device 4 is open, until that outside of the post body 6, over which the clamping arms of the clamping clamp 9 project, strikes the associated edge of the building part 19. In this respect, the lower end of the post body 6 below the clamping surface 24 forms a stop 27, by means of which the inner part 8 prevents the structural part 19 from touching. Then, with the aid of a wrench, the actuating member 11 is rotated, as a result of which the lower clamping surfaces 23 are raised relative to the post body 6, without the post body 6 even having to perform a vertical movement relative to the structural part 9. The clamping clamp 9 is then braced with a predetermined torque in relation to the building part 19. At the latest afterwards, but possibly also before the final bracing with respect to the structural part 19, at least one railing rod 3 is fastened with the fastening device 5 on the outside of the post body 6, via which the clamping clamp 9 also projects. Two or three fastening devices 5 or railing rods 3 lying one above the other at a distance are expedient provided, the uppermost of which protrudes beyond the upper end of the post body 6 and possibly the actuator 11 and forms a handrail.

Bei der Ausführungsform nach Fig. 2 ist die Befestigungsvorrichtung 4a nach Art eines Spanndornes 9a für eine Innenspannung derart ausgebildet, daß die Spannflächen 23a, 24a bei der Spannung voneinander weg bewegt werden. Zu diesem Zweck ist im Bereich des unteren Endes des Pfostenkörpers 6a ein einziger, gehäuseartig hohler Querarm 21a befestigt, der als Steckzapfen zum Einführen in ein an ihn angepaßtes hohles Gegenglied 18a dient. Dieses Gegenglied 18a ist am Bauwerkteil 19a z.B. durch Einbettung zu befestigen und besteht im wesentlichen aus einem Rohrabschnitt 22a größeren, jedoch annähernd gleichen Querschnittes wie der Spanndorn 9a sowie einer am äußeren Ende befestigten Flanschplatte 28 und einem am inneren Ende z.B. durch Einstecken befestigten Verschlußdeckel 29 aus Kunststoff o.dgl.. Das Gegenglied 18a wird zweckmäßig so in den Bauwerkteil 19a eingebettet, daß die Flanschplatte 28 bündig mit einer aufrechten Kantenfläche des Bauwerkteiles 19a abschließt. Zweckmäßig sind in der Flanschplatte 28 Durchgangsbohrungen für Nägel o.dgl. vorgesehen, mit welchen das Gegenglied 18a an der Innenseite der der Herstellung des Bauwerkteiles 19a dienenden Schalung befestigt werden kann.In the embodiment according to FIG. 2, the fastening device 4a is designed in the manner of a mandrel 9a for internal clamping such that the clamping surfaces 23a, 24a are moved away from one another during the clamping. For this purpose, a single, housing-like hollow cross arm 21a is fastened in the region of the lower end of the post body 6a and serves as a plug-in pin for insertion into a hollow counter member 18a adapted to it. This counter member 18a is on the structural part 19a e.g. to be fixed by embedding and essentially consists of a tube section 22a of larger, but approximately the same cross-section as the mandrel 9a and a flange plate 28 attached to the outer end and one at the inner end e.g. plastic plug or the like fastened closure cover 29. The counter member 18a is expediently embedded in the structural part 19a in such a way that the flange plate 28 is flush with an upright edge surface of the structural part 19a. 28 through holes for nails or the like are expedient in the flange plate. Provided with which the counter member 18a can be attached to the inside of the formwork used to manufacture the structural part 19a.

Das im wesentlichen innerhalb des Querarmes 21a liegende Spannglied 17a ist zweckmäßig nach Art eines zweiarmigen Hebels ausgebildet, dessen näher beim freien Ende des Querarmes 21a liegender Arm mit einem im wesentlichen durch eine Hebellängsseite gebildeten Bereich geringfügig nach oben über die Außen- bzw. Oberseite des Querarmes 21a vorsteht und mit diesem Bereich die in Seitenansicht konvex gekrümmte Spannfläche 23a bildet. Dieser Bereich des Spanngliedes 17a, der annähernd über die gesamte zugehörige Innenbreite des Querarmes 21a reicht, ragt durch eine Fensteröffnung 31, die in der oberen Wandung des Querarmes 21a und nahe benachbart zu dessen freiem, mit einer Endplatte verschlossenen Ende vorgesehen ist.The tendon 17a lying essentially within the transverse arm 21a is expediently designed in the manner of a two-armed lever, the arm of which lies closer to the free end of the transverse arm 21a with an area essentially formed by a longitudinal side of the lever slightly upwards over the outer or upper side of the transverse arm 21a protrudes and forms with this area the convexly curved clamping surface 23a in side view. This area of the tendon 17a, which extends approximately over the entire associated inner width of the cross arm 21a, projects through a window opening 31 which is provided in the upper wall of the cross arm 21a and closely adjacent to its free end closed with an end plate.

Das Spannglied 17a ist mit dem innerhalb des Pfostenkörpers 6a liegenden Spindeltrieb über einen Lenkertrieb 30 verbunden, der im wesentlichen innerhalb des Querarmes 21a liegt. Die Spindelmutter 13a trägt im Abstand unterhalb der Spindel 12a eine Lagergabel 32, mit welcher das eine Ende eines zweiarmigen, sich etwa in Längsrichtung des Querarmes 21a erstreckenden Lenkers 33 gelenkig verbunden ist. Die gelenkige Verbindung erfolgt durch einen in mindestens ein Langloch eingreifenden Gelenkbolzen 34. Etwa in der Mitte zwischen seinen Enden ist der Lenker 33 innerhalb des Querarmes 21a mit einem Lager 35 an dem Querarm 21a schwenkbar gelagert. Der vom Pfostenkörper 6a abgekehrte Arm des Lenkers 33 ist gelenkig mit dem von der Spannfläche 23a abgekehrten Arm des Spanngliedes 17a verbunden, wobei auch dieses Gelenk durch einen in mindestens ein Langloch eingreifenden Gelenkbolzen 36 gebildet ist. Zweckmäßig ist dieser Arm des Spanngliedes 17a als Gelenkgabel ausgebildet, zwischen deren Gabelwangen der Lenker 33 eingreift. Das Spannglied 17a ist mit einem es durchsetzenden Lagerbolzen 7a an dem Querarm 21a gelagert. Sämtlicher Lager- und Gelenkachsen liegen im wesentlichen parallel zueinander und rechtwinklig zur gemeinsamen Mittelebene des Pfostenkörpers 6a und des Querarmes 21a.The tensioning member 17a is connected to the spindle drive located inside the post body 6a via a link drive 30 which lies essentially within the transverse arm 21a. The spindle nut 13a carries a bearing fork 32 at a distance below the spindle 12a, with which the one end of a two-armed arm 33, which extends approximately in the longitudinal direction of the transverse arm 21a, is connected in an articulated manner. The articulated connection is made by means of a hinge pin 34 engaging in at least one elongated hole. Approximately in the middle between its ends, the link 33 is pivotably mounted within the cross arm 21a with a bearing 35 on the cross arm 21a. The arm of the link 33 facing away from the post body 6a is connected in an articulated manner to the arm of the tensioning member 17a facing away from the clamping surface 23a, this joint also being formed by a pivot pin 36 engaging in at least one elongated hole. This arm of the tension member 17a is expediently designed as an articulated fork, between the fork cheeks of which the handlebar 33 engages. The tensioning member 17a is mounted on the cross arm 21a with a bearing bolt 7a passing through it. All bearing and joint axes are essentially parallel to one another and at right angles to the common central plane of the post body 6a and the cross arm 21a.

Wird das Betätigungsglied 11a so gedreht, daß sich die Spindelmutter 13a nach unten bewegt, so wird die Spannfläche 23a in den Querarm 21a zurückgezogen. Bei Bewegung der Spindelmutter 13a nach oben legt sich die Spannfläche 23a an der oberen Innenfläche des Gegengliedes 18a an, während die davon abgekehrte, untere Außenseite des Querarmes 21a die zweite Spannfläche 24a bildet, die sich gegenüber der unteren Innenfläche des Gegengliedes 18a verspannt. Der Lenkertrieb 30 kann dabei so ausgebildet sein, daß er ebenfalls einen Untersetzungstrieb bildet, so daß ein zweistufiger Untersetzungstrieb zwischen dem Betätigungsglied 11a und dem Spannglied 17a vorgesehen ist.If the actuator 11a is rotated so that the spindle nut 13a moves downward, the clamping surface 23a is withdrawn into the cross arm 21a. When the spindle nut 13a moves upward, the clamping surface 23a rests on the upper inner surface of the counter member 18a, while the lower outer side of the cross arm 21a facing away from it forms the second clamping surface 24a, which braces against the lower inner surface of the counter member 18a. The handlebar drive 30 can be designed so that it also forms a reduction drive, so that a two-stage reduction drive is provided between the actuator 11a and the tension member 17a.

Die Befestigungsvorrichtung 4a ist so ausgebildet, daß zwischen der inneren Außenfläche 27a des Geländerpfostens 2a und der gegenüberliegenden Seitenfläche des Bauwerkteiles 19a bzw. dem äußeren Ende des Gegengliedes 18a oder der Flanschplatte 28 innerhalb verhältnismäßig großer Grenzen stufenlos ein Abstand eingestellt werden kann, der zweckmäßig in der Größenordnung von 70 mm liegt. Dadurch werden selbst bei lagestarr montiertem Geländerpfosten 2a solche Arbeiten im Bereich der Trittfläche des Bauwerkteiles 19a nicht behinert, die seitlich über diesen Bauwerkteil 19a hinausreichen. Der einspringende Winkel zwischen der inneren Außenfläche des Geländerpfostens 2a und der oberen Längsfläche des Spanndornes 9a ist dabei von Verstrebungen o.dgl. frei, so daß zwischen der Seitenfläche des Bauwerkteiles 19a und der Außenfläche 27a eine bis an die Oberseite des Spanndornes 9a reichende Lücke frei bleibt.The fastening device 4a is designed such that between the inner outer surface 27a of the railing post 2a and the opposite side surface of the structural part 19a or the outer end of the counter member 18a or the flange plate 28, a distance can be set within relatively large limits, which is expedient in the Order of magnitude of 70 mm. As a result, even when the railing post 2a is mounted rigidly in position, such work in the area of the tread surface of the building part 19a that extends laterally beyond this building part 19a is not impeded. The protruding angle between the inner outer surface of the railing post 2a and the upper longitudinal surface of the mandrel 9a is of struts or the like. free, so that a gap extending up to the top of the mandrel 9a remains free between the side surface of the structural part 19a and the outer surface 27a.

Nach dem Lösen und Entfernen des Geländerpfostens 2a verbleibt das Gegenglied 18a am Bauwerk, so daß es dafür geeignet ist, an ihm den Geländerpfosten eines endgültigen Geländers z.B. durch Vergießen oder ebenfalls lösbar zu befestigen. Ansonsten sind in den Fig. 1 bis 4 und 7, 8 für einander entsprechende Teile jeweils die gleichen Bezugszahlen, jedoch mit unterschiedlichen Buchstabenindizes verwendet, weshalb die entsprechenden Beschreibungsteile für alle Figuren gelten.After releasing and removing the railing post 2a, the counter member 18a remains on the structure, so that it is suitable for attaching to it the railing post of a final railing, e.g. to be fixed by casting or also releasably. Otherwise, the same reference numerals are used in FIGS. 1 to 4 and 7, 8 for corresponding parts, but with different letter indices, which is why the corresponding description parts apply to all figures.

Die Befestigungsvorrichtung 4b nach Fig. 3 ist ebenfalls für die Innenspannung im wesentlichen als Spanndorn nach Art einer Innen-Spannzange 9b ausgebildet. Zu diesem Zweck ist der Querarm 21b seitlich an beiden gegenüberliegenden Seiten längsgeschlitzt, so daß sich zwei über den größten Teil seiner Länge im wesentlichen frei ausragende, im Querschnitt jeweils U-förmige Zangenarme 25b ergeben, die übereinander liegen und mit den voneinander abgekehrten Außenseiten ihrer U-Querschenkel Spannflächen 23b bilden. In jedem dieser Spannarme 25b ist ein Keilstück derart befestigt, daß die einander zugekehrten Keilflächen in Richtung zum freien Ende des Querarmes 21b divergieren. An den Keilflächen 7b ist ein innen liegender Spannkeil 8b mit entsprechenden Keilflächen geführt. Der Spannkeil 8b weist ein im wesentlichen in der Mittelachse des Querarmes 21b liegendes Innengewinde 13b auf, in welches die Spindel 12b eingeschraubt ist. Die parallel bzw. koaxial zum Querarm 21b liegende Spindel 12b liegt mit dem größten Teil ihrer Länge innerhalb des Querarmes 21b und durchsetzt das untere Ende des Pfostenkörpers 6b quer, derart, daß sie an dessen von dem Querarm 21b abgekehrten Außenseite nach außen geführt ist und an dieser Außenseite das Betätigungsglied 11b trägt. Mit der im Axiallager 14b gesicherten Spindel 12b kann der Querarm 21b gespreizt und rückfedernd wieder verengt werden, wobei der Querarm 21b zweckmäßig einem Gegenglied ähnlich demjenigen nach Fig. 2 zugeordnet ist.The fastening device 4b according to FIG. 3 is also essentially designed for the internal clamping as a mandrel in the manner of an internal collet 9b. For this purpose, the cross arm 21b is laterally on both opposite sides slotted longitudinally so that there are two pliers arms 25b which project substantially over most of their length and are U-shaped in cross-section, which lie one above the other and form clamping surfaces 23b with the outer sides of their U-cross legs facing away from one another. A wedge piece is fastened in each of these clamping arms 25b in such a way that the wedge surfaces facing one another diverge in the direction of the free end of the transverse arm 21b. An internal clamping wedge 8b with corresponding wedge surfaces is guided on the wedge surfaces 7b. The clamping wedge 8b has an internal thread 13b which lies essentially in the central axis of the transverse arm 21b and into which the spindle 12b is screwed. The spindle 12b lying parallel or coaxial to the transverse arm 21b lies with most of its length within the transverse arm 21b and passes transversely through the lower end of the post body 6b, in such a way that it is guided outwards on the outside thereof facing away from the transverse arm 21b this outside carries the actuator 11b. With the spindle 12b secured in the axial bearing 14b, the cross arm 21b can be spread and narrowed again in a resilient manner, the cross arm 21b being expediently assigned to a counter member similar to that according to FIG. 2.

Bei der Ausführungsform nach Fig. 4 ist die Spannrichtung der Befestigungsvorrichtung 4c bzw. der Spannzwinge horizontal bzw. rechtwinklig zum Pfostenkörper 6c vorgesehen, dessen unteres Ende unmittelbar eine Spannbacke 18c derart bildet, daß die dem anderen Spannglied 17c zugekehrte Außenfläche des Pfostenkörpers 6c als Spannfläche 24c vorgesehen ist. Oberhalb der Spannfläche 24c steht über die zugehörige Außenseite des Pfostenkörpers 6c eine zu diesem rechtwinklige Teleskopführung 7c vor, deren Außenrohr lagefest am Pfostenkörper 6c befestigt ist. Die Teleskop-Innenstange 8c trägt das im Winkel zu ihr liegende, zugehörige Spannglied 17c, das im Bereich seines freien Endes mit einer über seine Innenseite vorstehenden Spannfläche 23c versehen ist. Die Stelleinrichtung 10c liegt ähnlich wie die Stelleinrichtung 10b gemäß Fig. 3 rechtwinklig zum Pfostenkörper 6c, und das Betätigungsglied 11c ist an der von dem bewegbaren Spannglied 17c abgekehrten Außenseite des Pfostenkörpers 6c vorgesehen. Dieser Geländerpfosten 2c dient insbesondere zur Befestigung an der Oberseite von aufrechten Mauern, wie Abstützmauern o.dgl., die z.B. im Straßenbau vorkommen können.In the embodiment according to FIG. 4, the clamping direction of the fastening device 4c or the clamping clamp is provided horizontally or at right angles to the post body 6c, the lower end of which directly forms a clamping jaw 18c such that the outer surface of the post body 6c facing the other clamping member 17c serves as the clamping surface 24c is provided. Above the clamping surface 24c there is a telescopic guide 7c at right angles to the outside of the post body 6c, the outer tube of which is fixed in position on the post body 6c. The telescopic inner rod 8c carries the associated tensioning member 17c lying at an angle to it, which is provided in the region of its free end with a tensioning surface 23c projecting beyond its inside. The 3 is perpendicular to the post body 6c, and the actuating member 11c is provided on the outside of the post body 6c facing away from the movable tensioning member 17c. This railing post 2c is used in particular for fastening to the top of upright walls, such as retaining walls or the like, which can occur, for example, in road construction.

Gemäß den Figuren 1, 2 und 5 bis 6 ist die jeweilige Geländerstange 3 zweckmäßig aus zwei oder drei teleskopartig ineinander verschiebbaren Metallprofilen 37, 38, 39 zusammengesetzt, die im Querschnitt annähernd rechtwinklig C-förmig sind. Jedes Metallprofil weist im Profil-Quersteg eine symmetrisch zu seiner zugehörigen Mittelebene liegende und sich im wesentlichen über seine gesamte Länge erstreckende Lochreihe aus lang-runden Stecklöchern 41 auf, deren Längserstreckung rechtwinklig zum Metallprofil liegt und die annähernd gleiche Abstände untereinander sowie bei allen Metallprofilen 37, 38, 39 haben, so daß die Stecklöcher ineinander gesteckter Metallprofile im wesentlichen deckungsgleich liegen können. Es ist auch denkbar, die Lochabstände in den einzelnen Metallprofilen geringfügig unterschiedlich zu wählen, um eine gegenüber dem Lochabstand feiner gestufte Verstellung insofern zu ermöglichen, daß in jeder Verstellungsstufe Stecklöcher deckungsgleich zueinander liegen.According to Figures 1, 2 and 5 to 6, the respective railing rod 3 is expediently composed of two or three telescopically displaceable metal profiles 37, 38, 39, which are approximately rectangular C-shaped in cross section. Each metal profile has a row of holes of long-round plug-in holes 41, which are symmetrical to its associated central plane and extend essentially over its entire length, in the crosspiece of the profile, the longitudinal extension of which is perpendicular to the metal profile and the approximately equal distances from one another and with all metal profiles 37, 38, 39 have, so that the plug-in holes of inserted metal profiles can be substantially congruent. It is also conceivable to select the hole spacing in the individual metal profiles slightly differently, in order to enable an adjustment that is finer than the hole spacing to the extent that plug-in holes are congruent with each other in each adjustment stage.

Die Stecklöcher 41 sind an Steckzapfen 40 der Geländerpfosten 2 angepaßt. Jeder Geländerpfosten 2 bzw. dessen Pfostenkörper 6 weist an der Seite, an welcher die Befestigungsvorrichtung vorsteht, zwei oder mehr solcher Steckzapfen 40 im Abstand übereinanderliegend jeweils in der Höhe auf, in welcher eine Geländerstange angebracht werden soll. Der jeweilige, im Querschnitt länglich rechteckige Steckzapfen 40, der zur Anpassung an eventuelle geneigte Lagen der Geländerstange auch um eine zum Geländerpfosten 2 etwa rechtwinklige Achse schwenkbar gelagert sein kann, ist Bestandteil der zugehörigen Befestigungsvorrichtung 5. Er dient zur Aufnahme eines ihn an seinen Flachseiten durchsetzenden, flachen Spannkeiles 42, der eine Keilöffnung 43 des Steckzapfens 40 durchsetzt. Dieser, in Montagelage zur Geländerstange etwa parallele Spannkeil 42 stützt sich mit einer schrägen, durch eine Schmalkante gebildeten Keilfläche an der vom Geländerpfosten 2 abgekehrten Begrenzung der Keilöffnung 43 ab und weist für die Anlage an der Innenseite des Profil-Quersteges des zugehörigen Metallprofiles eine durch eine Kantenfläche gebildete Keilfläche auf, die im wesentlichen ganzflächig an dieser Innenseite des Quersteges anliegt.The plug holes 41 are adapted to plug pins 40 of the railing posts 2. Each railing post 2 or its post body 6 has, on the side on which the fastening device projects, two or more such spigots 40 one above the other at a distance in each case at the height at which a railing rod is to be attached. The respective plug pin 40, which is rectangular in cross-section and which can also be pivoted about an axis which is approximately perpendicular to the railing post 2 in order to adapt to any inclined positions of the railing rod, is a component of the associated fastening device 5. It serves to receive a flat clamping wedge 42 penetrating it on its flat sides and penetrating a wedge opening 43 of the plug pin 40. This clamping wedge 42, which is approximately parallel in the assembly position to the railing rod, is supported with an oblique wedge surface formed by a narrow edge on the boundary of the wedge opening 43 facing away from the railing post 2 and has one for by the system on the inside of the profile crossbar of the associated metal profile Edge surface formed wedge surface, which rests essentially over the entire surface on this inside of the crossbar.

An seinem verjüngten Ende ist der Spannkeil 42 mit einem gegenüber der Keilöffnung 43 erweiterten, beispielsweise durch einen Kugelkopf gebildeten Sicherungsglied 44 versehen, welches den Spannkeil 42 dagegen sichert, vollständig vom Steckzapfen 40 abgenommen werden zu können. Bei Anlage des Sicherungsgliedes 44 an der zugehörigen Seitenfläche des Steckzapfens 40 kann der Spannkeil 42 durch Verschwenken etwa parallel zum Steckzapfen 40 ausgerichtet werden. Die Abmessungen sind dabei so vorgesehen, daß der Spannkeil 42 mit dem Steckzapfen 40 dann in eine Stecköffnung 41 eingeführt bzw. aus dieser herausgezogen werden kann. Der Steckzapfen 40 und der Spannkeil 42 und somit die gesamte Befestigungsvorrichtung 5 liegen im Spannzustand im wesentlichen vollständig innerhalb der Geländerstange 3 bzw. des zugehörigen Metallprofiles.At its tapered end, the clamping wedge 42 is provided with a securing element 44 which is enlarged compared to the wedge opening 43 and is formed, for example, by a spherical head, which secures the clamping wedge 42 against being able to be completely removed from the plug pin 40. When the securing member 44 rests on the associated side surface of the plug pin 40, the clamping wedge 42 can be aligned approximately parallel to the plug pin 40 by pivoting. The dimensions are provided in such a way that the clamping wedge 42 with the plug pin 40 can then be inserted into or pulled out of a plug opening 41. The plug pin 40 and the clamping wedge 42 and thus the entire fastening device 5 are essentially completely within the railing rod 3 or the associated metal profile in the tensioned state.

Sind zwei oder mehr ineinander gesteckte Metallprofile im Bereich des jeweiligen Geländerpfostens 2 vorgesehen, so durchsetzt der Steckzapfen 40 Stecklöcher 41 sämtlicher Metallprofile, wodurch diese gegeneinander in Längsrichtung der Geländerstange 3 lagegesichert bzw. arretiert sind. Insofern bildet die Befestigungsvorrichtung 5 gleichzeitig eine Arretierung der Metallprofile 37, 38, 39 gegeneinander.If two or more metal profiles inserted into one another are provided in the area of the respective railing post 2, the plug pin 40 passes through plug holes 41 in all metal profiles, as a result of which these are secured or locked in position in the longitudinal direction of the railing rod 3. In this respect, the fastening device 5 simultaneously forms a locking mechanism between the metal profiles 37, 38, 39.

Es ist auch denkbar, die Metallprofile durch gesonderte, im Abstand vom jeweiligen Geländerpfosten 2 liegende Sicherungsglieder, wie Bolzen, gegeneinander zu sichern, die dann deckungsgleiche Stecklöcher 41 durchsetzen. Durch die Befestigungsvorrichtung 5 wird die Außenseite des Quersteges des jeweils größten Metallprofiles 37 unmittelbar gegen die zugehörige, ebene Außenseite des Geländerpfostens 2 gespannt.It is also conceivable to secure the metal profiles against one another by means of separate securing members, such as bolts, which are at a distance from the respective railing post 2 and which then pass through congruent plug-in holes 41. The outside of the crossbar of the largest metal profile 37 is stretched directly against the associated flat outside of the railing post 2 by the fastening device 5.

Zur Verbindung von Abschnitten der Längsläufe bzw. Geländerstangen 3, die in Seitenansicht gemäß Fig. 5 und/oder in Draufsicht gemäß Fig. 6 im Winkel aneinanderschließen sollen, ist zweckmäßig eine Winkelverbindung 45 vorgesehen, die als einstellbare Gelenkverbindung ausgebildet sein kann. und ebenfalls Spannmittel bildet. Im dargestellten Ausführungsbeispiel ist die Winkelverbindung 45 dafür vorgesehen, die Abschnitte der Geländerstange 3 so zu verbinden, daß sie in Seitenansicht wahlweise fluchtend oder innerhalb vorbestimmter Grenzen im Winkel zueinander liegen, wobei die Abschnitte aus der fluchtenden Lage in beiden entgegengesetzten Richtungen gegeneinander winkelverstellt werden können.An angle connection 45, which can be designed as an adjustable joint connection, is expediently provided to connect sections of the longitudinal runs or railing rods 3 which are to be angled in the side view according to FIG. 5 and / or in the top view according to FIG. 6. and also forms clamping devices. In the illustrated embodiment, the angle connection 45 is provided to connect the sections of the railing rod 3 such that they are either aligned in side view or at an angle to one another in a side view, wherein the sections can be angularly adjusted in opposite directions from one another in the aligned position.

Am Ende des kleinsten bzw. innersten Metallprofiles 39 eines Abschnittes der Geländerstange 3 ist zu diesem Zweck mindestens eine Verbindungsplatte 46 befestigt, wobei zweckmäßig jeweils an der Innenseite und an der Außenseite des Profil-Quersteges jeweils eine Verbindungsplatte 46 derart lagestarr befestigt ist, daß die beiden im wesentlichen deckungsgleichen und in geringem Abstand parallel zueinander liegenden Verbindungsplatten 46 frei über das Ende dieses Metallprofiles 39 vorstehen. Die Verbindungsplatten 46 greifen in das Ende eines entsprechenden Metallprofiles 39 des anderen Geländerstangen-Abschnittes ein und sind mit diesem über ein Gelenk 47 verbunden, dessen Gelenkachse im wesentlichen rechtwinklig zur Längsrichtung der Geländerstange 3 und annähernd horizontal in der Längsmittelebene des zugehörigen Gelän derstangen-Abschnittes liegt.At the end of the smallest or innermost metal profile 39 of a section of the railing rod 3, at least one connecting plate 46 is fastened for this purpose, a connecting plate 46 being expediently fastened in each case on the inside and on the outside of the profile crosspiece such that the two essentially congruent and at a small distance parallel to each other connecting plates 46 protrude freely over the end of this metal profile 39. The connecting plates 46 engage in the end of a corresponding metal profile 39 of the other railing rod section and are connected to this via a hinge 47, the hinge axis of which is substantially perpendicular to the longitudinal direction of the railing rod 3 and approximately horizontally in the longitudinal central plane of the associated railing rod section .

Im dargestellten Ausführungsbeispiel liegen die beiden Verbindungsplatten 46 im Bereich des Gelenkes 47 an der Innen-und an der Außenseite des Profil-Quersteges des zugehörigen Metallprofiles nach Art von Spannpratzen an. Beide Verbindungsplatten 46 sowie der zugehörige Profil-Quersteg werden von zwei Bolzen 49 durchsetzt, die quer zur Längsmittelebene des zugehörigen Metallprofiles 39 im Abstand zueinander liegen. Diese Bolzen 49 durchsetzen in den Verbindungsplatten 46 oder im Profil-Quersteg Langlöcher 48, die sich im wesentlichen um die genannte Gelenkachse erstrecken bzw. angenähert an eine solche Lage im spitzen Winkel zueinander liegen, wobei die Bolzen 49 mit entsprechendem Querspiel in die Langlöcher 48 eingreifen. Durch Festziehen der Bolzen 49, die z.B. durch Schraubenbolzen mit Muttern oder durch im Profil vorgesehene Gewinde eingeschraubte Schrauben gebildet sein können, wird das Gelenk 47 in der eingestellten Lage festgesetzt. Durch entsprechende Winkelstellung und/oder Krümmung der Langlöcher läßt sich der maximal begrenzte Schwenkwinkel verändern. Durch den Abstand beider Schrauben ist eine sichere Spannung mit großem Hebelarm möglich. Durch Lösen der Bolzen 49 läßt sich auch die Winkelverbindung 45 lösen. Des weiteren ist es denkbar, Gelenke 47 im Bereich beider aneinanderschließender Metallprofile 39 vorzusehen. Durch die beschriebene Ausbildung kann die Winkelverbindung 45 im wesentlichen vollständig innerhalb der aneinanderschließenden Metallprofile 39 liegen.In the exemplary embodiment shown, the two connecting plates 46 rest in the region of the joint 47 on the inside and on the outside of the profile crossbar of the associated metal profile in the manner of clamping claws. Both connecting plates 46 and the associated profile crossbar are penetrated by two bolts 49 which are spaced apart from one another transversely to the longitudinal center plane of the associated metal profile 39. These bolts 49 penetrate elongated holes 48 in the connecting plates 46 or in the cross-piece of the profile, which essentially extend around the articulated axis or are approximately at such an angle at an acute angle, the bolts 49 engaging in the elongated holes 48 with a corresponding transverse play . By tightening the bolts 49, e.g. The hinge 47 is fixed in the set position by bolts with nuts or by screws screwed into the profile. The maximum limited swivel angle can be changed by appropriate angular position and / or curvature of the elongated holes. The distance between the two screws enables secure clamping with a large lever arm. By loosening the bolts 49, the angle connection 45 can also be released. Furthermore, it is conceivable to provide joints 47 in the area of both mutually adjoining metal profiles 39. Due to the design described, the angle connection 45 can lie essentially completely within the metal profiles 39 which are connected to one another.

Zumindest die beiden größeren Metallprofile 37, 38 können jeweils eine Länge von etwa 2 m haben, während das kleinste Metallprofil 39 demgegenüber zweckmäßig kürzer ist. Die Metallprofile 37, 38, 39 bestehen bevorzugt aus Aluminium. Es sind aber auch Kunststoff-Profile denkbar.At least the two larger metal profiles 37, 38 can each have a length of approximately 2 m, while the smallest metal profile 39, on the other hand, is expediently shorter. The metal profiles 37, 38, 39 are preferably made of aluminum. But plastic profiles are also conceivable.

Bei der Ausführungsform nach den Fig. 7 und 8 ist jeder Spannarm 17d, 18d durch ein V-Profil 21d bzw. 22d gebildet, das zweckmäßig durch entsprechendes Abkanten eines Blechstreifens hergestellt ist. Beide Blechprofile können gleich ausgebildet sein und sind jeweils nach Art eines frei über seine gesamte Länge ausragenden Armes am Pfostenkörper 2d befestigt. Der obere Spannarm 18d ist an der unteren Endfläche des Pfostenkörpers 6d bzw. des Teleskop-Außenrohres so durch Schweißen befestigt, daß er bis an dessen äußere Außenfläche reicht. Entsprechend ist der untere Spannarm 17d an der unteren Endfläche der Teleskop-Innenstange 8d befestigt. Der obere Spannarm 18d ist von zusätzlichen Versteifungs-Verstrebungen, wie sie z.B. in Fig. 1 dargestellt sind, in diesem Fall frei, so daß er eine gegenüber dem unteren Spannarm 17d geringfügig größere Biegeelastizität aufweist. Dieser untere Spannarm 17d ist mit einer zusätzlichen, winkelförmigen Versteifung verstärkt, die mit einem kürzeren Schenkel an der äußeren Außenfläche der Teleskop-Innenstange 8d und mit einem längeren Winkelschenkel an der von der zugehörigen Spannfläche 23d abgekehrten Unterseite des Spannarmes 17d durch Schweißen befestigt sowie stegförmig und schmaler sowohl als die Innenstange 8d als auch als der Spannarm 17d ist.In the embodiment according to FIGS. 7 and 8, each tensioning arm 17d, 18d is formed by a V-profile 21d or 22d, which is expediently made by bending a sheet metal strip accordingly is made. Both sheet metal profiles can be of the same design and are each attached to the post body 2d in the manner of an arm which projects freely over its entire length. The upper tension arm 18d is fixed to the lower end surface of the post body 6d or the telescopic outer tube by welding so that it extends to the outer outer surface thereof. Accordingly, the lower tension arm 17d is fixed to the lower end surface of the telescopic inner rod 8d. The upper clamping arm 18d is free of additional stiffening struts, such as are shown in FIG. 1, in this case, so that it has a slightly greater bending elasticity than the lower clamping arm 17d. This lower clamping arm 17d is reinforced with an additional, angular stiffening, which is fastened by welding with a shorter leg on the outer outer surface of the telescopic inner rod 8d and with a longer angle leg on the underside of the clamping arm 17d facing away from the associated clamping surface 23d, and also in the form of a web and is narrower than both the inner rod 8d and the tension arm 17d.

Die untere Endfläche des Pfostenkörpers 6d ist mit einer an das Profil des Spannarmes 18d angepaßten V-förmigen Nut versehen, so daß der jeweilige Profilschenkel des Spannarmes 18d im Querschnitt an die zugehörige Außenfläche des Pfostenkörpers 6d stumpfwinklig anschließt und seitlich über diese Außenfläche vorsteht. Das zugehörige Ende des Spannarmes 18d ist mit einer an die Innenquerschnitte des Pfostenkörpers 6d angepaßten Durchgangsöffnung versehen, welche von der Innenstange 8d durchsetzt wird. Das untere Ende dieser Innenstange 8d ist durch V-förmige Zuspitzung an den Innenquerschnitt des Spannarmes 17d angepaßt, der bis an die äußere Außenfläche der Innenstange 8d bzw. bis an den zugehörigen Schenkel des Versteifungswinkels 52 reicht und dessen Profilschenkel ebenfalls seitlich beiderseits über die Innenstange 8d vorstehen.The lower end face of the post body 6d is provided with a V-shaped groove adapted to the profile of the tensioning arm 18d, so that the respective profile leg of the tensioning arm 18d connects in cross section at an obtuse angle to the associated outer surface of the post body 6d and projects laterally beyond this outer surface. The associated end of the tensioning arm 18d is provided with a through opening which is adapted to the inner cross sections of the post body 6d and is penetrated by the inner rod 8d. The lower end of this inner rod 8d is adapted by V-shaped tapering to the inner cross section of the clamping arm 17d, which extends to the outer outer surface of the inner rod 8d or to the associated leg of the stiffening angle 52 and whose profile leg also laterally on both sides via the inner rod 8d protrude.

Die Profilschenkel der beiden Spannarme 17d, 18d sind gegeneinander gerichtet und bilden jeweils mit einer Kante jeder Kantenfläche Spannflächen-Bereiche 23d, 24d. Die Spannflächen-Bereiche 23d, 24d jedes Spannarmes 17d bzw. 18d liegen parallel zueinander in einem Abstand voneinander, der größer als die Dicke des Geländerpfostens 2d ist, wobei sich jedoch jeweils zwei Spannflächen-Bereiche 23d, 24d in einer zur Längsrichtung des Geländerpfostens 2s parallelen Richtung deckungsgleich gegenüberliegen. Dadurch ergibt sich eine sehr genau definierte Anlage der Spannarme 17d, 18d an den zugehörigen Oberflächen des Bauwerkteiles 19d.The profile legs of the two clamping arms 17d, 18d are directed towards one another and each form clamping area regions 23d, 24d with an edge of each edge surface. The clamping surface areas 23d, 24d of each clamping arm 17d or 18d are parallel to one another at a distance from one another which is greater than the thickness of the railing post 2d, but two clamping surface areas 23d, 24d each parallel to the longitudinal direction of the railing post 2s Opposite direction. This results in a very precisely defined contact of the tension arms 17d, 18d on the associated surfaces of the building part 19d.

Wie die Fig. 7 und 8 weiter zeigen, ist an der äußeren Außenseite des Pfostenkörpers 6d des Geländerpfostens 2d eine Halterung 50 vorgesehen, die z.B. durch drei in gleichmäßigen Abständen übereinanderliegende und gleiche Bügel 51 gebildet ist, die schmaler als die zugehörige Außenseite des Pfostenkörpers 6d sind. Jeder Bügel 51 ist mit den Endflächen seiner Bügelschenkel an der genannten Außenseite des Pfostenkörpers 6d durch Schweißen befestigt, wobei der obere Bügelschenkel des obersten Bügels 51 zweckmäßig unmittelbar an das obere Ende des Pfostenkörpers 6d anschließt und der untere Bügelschenkel des untersten Bügels 51 nahe benachbart zur unteren Endfläche dieses Pfostenkörpers 6d liegt. Jeder Bügel 51 begrenzt in Seitenansicht gemäß Fig. 7 mit dem Pfostenkörper 6d eine flach rechteckige Bügel- bzw. Durchgangsöffnung, deren größere Querschnittserstreckung in Höhenrichtung des Geländerpfostens 2d liegt und deren Querschnittserstreckung quer zur Pfostenlängsrichtung etwa in der Größenordnung der Pfostendicke gewählt ist.As FIGS. 7 and 8 further show, a holder 50 is provided on the outer outside of the post body 6d of the railing post 2d, which e.g. is formed by three identical brackets 51 lying one above the other at equal intervals and which are narrower than the associated outer side of the post body 6d. Each bracket 51 is fastened with the end faces of its bracket legs to the aforementioned outer side of the post body 6d by welding, the upper bracket leg of the uppermost bracket 51 expediently directly adjoining the upper end of the post body 6d and the lower bracket leg of the lowest bracket 51 closely adjacent to the lower one End surface of this post body 6d is. 7 with the post body 6d delimits a flat rectangular bracket or passage opening, the larger cross-sectional extent of which lies in the height direction of the railing post 2d and the cross-sectional extent transverse to the longitudinal direction of the post is selected approximately in the order of magnitude of the post thickness.

Fig. 9 und 10 zeigen einen Geländerpfosten 6b, der aus einem runden oder vierkantigen Rohr besteht, in dessen unterem Ende ein Flansch 50 in Form einer viereckigen Platte aufgeschweißt ist. In der Platte ist ein langgestreckter, rechteckiger Schlitz 51 vorgesehen und auf der Unterseite des Flansches ist ein Rohrstück angeschweißt, das die Befestigungsvorrichtung 4b bildet, die, wie die nach Fig. 3, als Innenspannzange 9b ausgebildet ist. Dazu ist das Rundrohrstück zu seinem unteren Ende her verjüngt und geschlitzt, so daß zwei Zangenarme 25b mit Halbrundschalenprofil entstehen, die durch den Schlitz 53 voneinander getrennt sind. In das Innere der Zangenarme kann ein Spannteil 8b eingetrieben werden, das durch den gesamten Geländerpfosten 6b bis zu dessen oberem Ende 54 verläuft und einen langgestreckten, rechteckigen Querschnitt entsprechend der Öffnung 51, die ihn führt, aufweist. Nahe dem unteren Ende ist ein Querstift 55 eingesetzt, so daß der stangenförmige Spannteil nicht nach oben herausgezogen werden kann, weil der Stift am Flansch 50 sperrt. In Fig. 9 ist die Konizität zur besseren Veranschaulichung übertrieben dargestellt.9 and 10 show a railing post 6b, which consists of a round or square tube, in the lower end of which a flange 50 is welded in the form of a square plate. An elongated, rectangular slot 51 is provided in the plate and on the underside of the A pipe section is welded onto the flange, which forms the fastening device 4b, which, like that according to FIG. 3, is designed as an internal collet 9b. For this purpose, the round tube piece is tapered and slotted towards its lower end, so that two tong arms 25b with a semicircular shell profile are formed, which are separated from one another by the slot 53. A clamping part 8b can be driven into the interior of the forceps arms, which extends through the entire railing post 6b up to its upper end 54 and has an elongated, rectangular cross section corresponding to the opening 51 which guides it. A cross pin 55 is inserted near the lower end so that the rod-shaped clamping part cannot be pulled out upwards because the pin locks on the flange 50. In Fig. 9, the taper is exaggerated for better illustration.

Im oberen Ende des Spannteils ist ein größeres Loch 56 vorgesehen, in das ein Werkzeug, beispielsweise der Pickel eines Maurerhammers, zum Herausziehen des Spannteils eingreifen kann.A larger hole 56 is provided in the upper end of the clamping part, into which a tool, for example the pick of a mason hammer, can engage in order to pull out the clamping part.

Der Steckzapfen 9b der Befestigungsvorrichtung 4b kann in ein beispielsweise in eine Betonplatte eingebohrtes Loch 57 eingeführt und durch Hineinschlagen des Spannteils 8b von oben her befestigt werden, wobei sich die Zangenarme 25b unter Querbewegung aufspreizen, wenn der Spannteil in das Innere zwischen den Zangenarmen eindringt. Es hat sich gezeigt, daß eine Aufweitung bis etwa auf die zylindrische Form meist zur Festlegung ausreicht. Sollte dies nicht der Fall sein und eine weitere Verankerung, beispielsweise bei weniger festem Untergrund, z.B. im Straßenbau, gewünscht werden, so kann die Aufspreizung auch über die Zylinderform hinausgehen, indem beispielsweise die Zangenarme 25b mit strichpunktiert angedeuteten Sicken 60, die sich nach unten verbreitern, versehen werden und/oder durch Aufbiegen der Ränder des Schlitzes 53 zusätzliche Greifflächen geschaffen werden, die beispielsweise auch widerhakenartig gestaltet werden könnten. Es wird damit ein Geländerpfosten geschaffen, der besonders einfach gestaltet ist und leicht in vorhandene oder zu bohrende Löcher in beliebigem Material einzusetzen ist. Auch er hat einen der Hauptvorteile der Erfindung, nämlich die große Montagezeitersparnis bei gleichzeitiger großer Zuverlässigkeit und Stabilität eines Notgeländers und die Materialersparnis durch die praktisch unbegrenzte Wiederverwendbarkeit.The plug pin 9b of the fastening device 4b can be inserted into a hole 57 drilled, for example, in a concrete slab and fastened by hammering in the clamping part 8b from above, the pliers arms 25b spreading apart with transverse movement when the clamping part penetrates into the interior between the pliers arms. It has been shown that an expansion up to approximately the cylindrical shape is usually sufficient for fixing. If this is not the case and further anchoring is desired, for example on less solid ground, e.g. in road construction, the spreading can also extend beyond the cylindrical shape, for example by the pliers arms 25b with beads 60 indicated by dash-dotted lines that widen downwards , are provided and / or by bending the edges of the slot 53 additional gripping surfaces are created that could also be designed like barbs, for example. This creates a railing post that is particularly simple and easy to insert into existing holes or holes in any material. It also has one of the main advantages of the invention, namely the large assembly time savings with great reliability and stability of an emergency railing and the material savings due to the practically unlimited reusability.
