Description

Die Erfindung betrifft ein Schloß, gemäß Oberbegriff des Anspruchs 1.The invention relates to a lock, according to the preamble of claim 1.

Ein derartiges Schloß ist beispielsweise aus dem US-Patent 5 189 893 bekannt. Bei dem bekannten Schloß werden starke Zugkräfte an dem Schließdorn, welche beispielsweise bei unerlaubten Aufbruchversuchen auf den Schließdorn ausgeübt werden, durch Abstützung an dem Stellelement und an einer das Stellelement beeinflussenden Blockiereinrichtung aufgenommen.Such a lock is for example from the US patent 5 189 893 known. In the well-known castle are strong Tensile forces on the locking pin, which for example unauthorized attempts to break open on the locking pin be, by support on the actuator and on a blocking device influencing the control element added.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Schloß mit Schloßkörper und Schließdorn so auszubilden, daß die sich bei starken Auszugskräften auf den Schließdorn einstellenden Reaktionskräfte von dem Stellelement und einer dem Stellelement zugeordneten Blockiereinrichtung möglichst ferngehalten werden.The present invention is based on the object Train the lock with the lock body and locking pin so that with strong pull-out forces on the locking pin adjusting reaction forces from the actuator and one blocking device assigned to the control element if possible be kept away.

Zur Lösung dieser Aufgabe werden die Merkmale des kennzeichnenden Teils des Anspruchs 1 vorgeschlagen.To achieve this object, the features of the characterizing part of claim 1 suggested.

Die erfindungsgemäße Schloßkonstruktion bringt den großen Vorteil, daß die empfindlichen Teile, Stellelement und Blockiereinrichtung, bei Aufbruchversuchen weitestgehend entlastet sind. Dies bedeutet, daß zum einen Aufbruchversuche erschwert sind und zum anderen auch erfolglose Aufbruchversuche nicht zu Deformationen an dem Stellelement und/oder der Blockiereinrichtung führen können. Damit besteht die Chance, daß ein Schloß erfindungsgemäßer Konstruktionsart auch Aufbruchversuche mit größter Kraftanlegung unbeschädigt überlebt.The lock construction according to the invention brings the big one Advantage that the sensitive parts, actuator and Blocking device, largely when trying to break open are relieved. This means that on the one hand attempts to break open are difficult and on the other hand unsuccessful attempts to break open not to deformation on the actuator and / or the blocking device can lead. In order to there is a chance that a lock construction type according to the invention also attempts to break open with the greatest power survived undamaged.

Das erfindungsgemäße Konstruktionsprinzip kann in der Weise verwirklicht werden, daß das Widerlager an einem vorzugsweise plattenförmigen Widerlagerelement ausgebildet ist, welches den Schließdorn in seiner Schließdornschließstellung wenigstens teilweise umfaßt und sich an diesem gegen eine im wesentlichen quer zur Schließdornauszugsrichtung gerichtete Querkraft abstützt, die sich bei Einwirkung einer Auszugskraft auf den Schließdorn als Folge der Einklemmung des Riegelelements zwischen Schließfläche und Widerlager ergibt. The construction principle according to the invention can be done in the way be realized that the abutment on a preferably plate-shaped abutment element is formed, which keeps the closing mandrel in its closing mandrel closing position at least partially embraced and opposed to it one essentially transverse to the closing mandrel extension direction directional shear force, which acts upon the action of a Pull-out force on the locking pin as a result of the pinching of the locking element between the closing surface and the abutment results.

Durch diese Weiterbildungsmaßnahme wird erreicht, daß der Schloßkörper selbst von Querkräften als Folge von Schließdornauszugskräften weitgehend entlastet ist. An dem Schloßkörper treten dann im wesentlichen nur noch zur Schließdornauszugsrichtung parallele Reaktionskräfte auf, die verhältnismäßig leicht und ohne großen Bau- und Materialaufwand aufgenommen werden können.This training measure ensures that the Lock body itself from transverse forces as a result of locking pin pull-out forces is largely relieved. On the lock body then essentially occur only to the closing mandrel extension direction parallel reaction forces that are proportional easily and without much construction and material can be included.

Um einerseits bei normaler Schloßbenutzung ein leichtgängiges Ein- und Ausfahren des Schließdorns in die Schließdornaufnahme zu ermöglichen, andererseits aber die Querkrafteinleitung von dem Widerlagerelement in den Schließdorn zu ermöglichen, kann dabei vorgesehen sein, daß das Widerlagerelement innerhalb des Schloßkörpers mit Bewegungsspiel quer zu der Schließdornauszugsrichtung gelagert ist.On the one hand, with normal lock use, it runs smoothly Retracting and extending the locking pin in the locking pin holder to enable, but on the other hand the introduction of lateral force from the abutment element into the closing mandrel To enable it can be provided that the abutment element within the lock body with play is mounted transversely to the closing mandrel extension direction.

Das Widerlagerelement kann an der Innenseite einer Gehäusewand des Schloßkörpers anliegen, so daß bei der Dimensionierung des Schlosses im Hinblick auf Ausreißversuche im wesentlichen nur noch auf die Bemessung der in Auszugsrichtung vordersten Gehäusewand des Schloßkörpers geachtet werden muß. Bevorzugt wird zum Zwecke der Querkrafteinleitung in den Schließdorn das Widerlagerelement mit einem den Schließdorn vollständig umschliessenden Durchbruch ausgeführt.The abutment element can be on the inside of a housing wall of the lock body so that when dimensioning the Essentially only with regard to attempts at pulling out still on the dimensioning of the foremost housing wall in the pull-out direction of the lock body must be respected. Is preferred to Purpose of the introduction of transverse force into the locking mandrel the abutment element with one completely enclosing the locking pin Breakthrough accomplished.

Das Widerlager kann von Kanten einer Schließdorndurchtrittsöffnung in dem Widerlagerelement gebildet sein. Dies erleichtert die Herstellung des Widerlagers, indem beispielsweise die Schließdorndurchtrittsöffnung und deren Erweiterung in einem einzigen Stanzvorgang hergestellt werden können. The abutment can from the edges of a mandrel passage opening be formed in the abutment element. This facilitates the production of the abutment by for example the closing mandrel passage opening and its Extension made in a single punching process can be.

Bei Rundquerschnitt des Schließdorns und Kugelform des Riegelelements ergibt sich als vorteilhafte Gestaltung eine schlüssellochförmige Durchbrechung des Widerlagerelements.With a round cross section of the locking pin and spherical shape of the Bolt element results in an advantageous design a keyhole-shaped opening in the abutment element.

Das erfindungsgemäße Prinzip ist insbesondere anwendbar, wenn das Riegelelement durch das Stellelement unter Federkraft in die Verriegelungsstellung vorgespannt ist und wenn der Schließdorn unter nockenartigem Zusammenwirken mit dem Riegelelement aus der Schließdornschließstellung zurückziehbar ist, wobei das Riegelelement in Richtung auf die Freigabestellung ausweicht.The principle according to the invention is particularly applicable if the locking element by the actuator under spring force is biased into the locking position and if the closing mandrel under cam-like interaction with the Bolt element retractable from the locking pin closing position is, the locking element in the direction of the Release position evades.

Bei einer solchen Ausführungsform ist es im Hinblick auf die normale Handhabung des Schlosses wünschenswert, daß keine allzu großen Auszugskräfte an den Schließdorn angelegt werden müssen, um den Schließdorn aus der Verrastung mit dem Riegelelement zu lösen. Dies führt zu Eingriffsverhältnissen zwischen Riegelelement und Schließfläche, die beim normalen Ausziehen des Schließdorns ein günstiges Übersetzungsverhältnis zwischen Auszugskraft und der auf das Riegelelement wirkenden Reaktionskraft ergeben. Gerade bei solchen günstigen Übersetzungsverhältnissen besteht aber andererseits die Gefahr, daß bei Aufbruchversuchen, wenn das Riegelelement durch die Blockiereinrichtung in der Verriegelungsstellung blockiert ist, große Reaktionskräfte auf das Riegelelement übertragen werden.In such an embodiment, it is in view of the normal handling of the lock desirable that none Excessively large pull-out forces applied to the locking pin must be removed from the locking pin with the Loosen locking element. This leads to interference between the locking element and the closing surface, which in normal Pulling out the locking pin has a favorable gear ratio between pull-out force and that on the locking element acting reaction force. Especially with such on the other hand, there are favorable translation ratios the risk that when trying to break open if the locking element by the blocking device in the locking position is blocked, great reaction forces to that Bolt element are transferred.

Bei der erfindungsgemäßen Gestaltung wird dies, wie schon angedeutet, durch die selbsthemmende Zusammenwirkung zwischen Schließdorn, Riegelelement und Widerlager des Schloßkörpers verhindert. In the design according to the invention, as will be the case indicated by the self-locking interaction between locking pin, locking element and abutment of the Lock body prevented.

Die Gestaltung der Schließfläche hängt natürlich von der Gestaltung des Schließelements ab. Benutzt man einen Wälzkörper und insbesondere eine Kugel als Schließelement, so empfiehlt es sich auch aus Gründen der Herstellungserleichterung, die Schließfläche als eine Teilzylinderfläche oder Kugelkalottenfläche auszubilden, wobei bei der Gestaltung der Schließfläche im einzelnen wiederum darauf zu achten ist, daß dem Ausziehen des Schließdorns bei gelöster Blockiereinrichtung ein Widerstand entgegenwirkt, der einerseits ein unbeabsichtigtes Herausfallen des Schließdorns aus der Schließdornaufnahme verhindert, andererseits aber auch das normale Handhaben des Schlosses nicht über Gebühr erschwert.The design of the closing surface naturally depends on the Design of the closing element. If you use one Rolling elements and in particular a ball as a closing element, it is also recommended to make production easier, the closing surface as a partial cylinder surface or form a spherical cap surface, with the design the closing surface in turn towards it make sure that the closing mandrel is pulled out when it is released Blocking device counteracts a resistance, on the one hand an unintentional falling out of the locking pin prevented from the locking pin holder, on the other hand also the normal handling of the lock is not excessive difficult.

Bei dem erfindungsgemäßen Konstruktionsprinzip tritt das Problem auf, daß bei normalem Ziehen des Schließdorns, d.h. bei gelöster Blockiereinrichtung, das Riegelelement nicht wesentlich in Eingriff mit dem Widerlager treten soll, denn das Auftreten eines solchen Eingriffs würde ja das Ausziehen des Schließdorns erschweren. Es wird deshalb weiter vorgeschlagen, daß unter Normalgebrauchsbedingungen das Riegelelement durch die Führungsbahn bis zum Eintritt in die Verriegelungsstellung im wesentlichen ohne ein in Schließdornauszugsrichtung bestehendes Spiel geführt ist und daß eine Verklemmung des in seiner Verriegelungsstellung blockierten Riegelelements zwischen der Schließfläche und dem Widerlager erst bei Überschreiten eines vorbestimmten Werts einer an den Schließdorn angelegten Auszugskraft unter elastischer Auslenkung des Riegelelements aus seiner Führungsbahn eintritt. Bis zum Eintreten der Verklemmung tritt demnach eine Reaktionskraft auf das Stellelement und auch auf die das Stellelement beeinflussende Blockiereinrichtung auf. Diese Reaktionskraft ist aber bei der Konstruktion des Schlosses leicht kalkulierbar. Auf eine elastische Auslenkung des Riegelelements wird deshalb Wert gelegt, weil man ja nach Aufhören einer großen Auszugskraft am Schließdorn das Schloß unverändert gebrauchsfähig haben will. Eine plastische Auslenkung des Riegelelements aus seiner Führungsbahn soll aber insbesondere für Spezialkonstruktionen nicht ausgeschlossen sein; hierbei wird insbesondere an Schlösser gedacht, die einer starken Auszugskraft in aller Regel nicht unterworfen werden und die, falls eine solche starke Auszugskraft einmal angelegt wird, nicht mehr gebrauchsfähig sind, vielleicht auch gar nicht mehr gebrauchsfähig sein sollen.This occurs in the construction principle according to the invention Problem on that with normal pulling of the closing mandrel, i.e. when the blocking device is released, the locking element is not should substantially engage the abutment, because the occurrence of such an intervention would undress of the closing pin. It is therefore further proposed that under normal conditions of use the locking element through the guideway until entering the Locking position essentially without one in the closing mandrel extension direction existing game is led and that a jam in its locked position blocked locking element between the closing surface and the abutment only when a predetermined value is exceeded Value of a pull-out force applied to the locking pin elastic deflection of the locking element from its guideway entry. Until the jam occurs accordingly a reaction force to the actuator and also to the blocking device influencing the control element on. This reaction force is in the construction of the Lock easily calculable. For an elastic deflection of the locking element is important because one after a large pull-out force on the locking pin the castle wants to remain usable. A plastic deflection of the locking element from its guideway but should especially for special constructions not be excluded; in particular, here Locks thought that have a strong pull-out force in all Usually not to be subjected and if such strong pull-out force is applied once, no longer usable are, maybe even no longer usable should be.

Eine Führungsbahn, welche die Forderung erfüllt, das Riegelelement bis zum Eintritt in die Verriegelungsstellung im wesentlichen ohne ein in Schließdornauszugsrichtung bestehendes Spiel zu führen, läßt sich durch einen Führungskanal innerhalb des Schloßkörpers verwirklichen, insbesondere einen Führungskanal, welcher derart elastisch ausweitbar ist, daß er bei Überschreiten einer vorbestimmten Auszugskraft an dem Schließdorn ein elastisches Ausweichen des Riegelelements aus seiner Führungsbahn in Schließdornauszugsrichtung gestattet. Ein solcher Führungskanal läßt sich insbesondere dann erreichen, wenn der Führungskanal von einem Kunststoffteil gebildet ist. Dabei kann das elastische Ausweichen noch durch Schlitzung des Führungskanals oder durch eine in Auszugsrichtung verjüngte Gestaltung des führungskanalsquerschnittsbegünstigt werden.A guide track that meets the requirement, the locking element until entry into the locking position in essentially without one existing in the direction of the mandrel extension Leading play can be done through a guide channel realize within the lock body, in particular a guide channel which can be expanded elastically in this way is that when a predetermined one is exceeded Pulling force on the locking pin an elastic dodge the locking element from its guideway in the closing mandrel extension direction allowed. Such a guide channel leaves reach themselves in particular if the guide channel of a plastic part is formed. The elastic Evasion by slitting the guide channel or by a tapered design of the guide channel cross section favored.

Das Stellelement kann, wie schon angedeutet, durch eine Blockiereinrichtung in seiner Sperrstellung blockierbar sein, wobei die Blockiereinrichtung bevorzugt auf der Basis eines handelsüblichen Schließzylinders aufgebaut wird. Dabei kann die Blockiereinrichtung mit einer drehbaren Kurvenscheibe ausgeführt sein, welche in einer Blockierstellung der Blockiereinrichtung ein Ausweichen des Stellelements aus der Sperrstellung in seine Rückzugsstellung blockiert und in einer Nichtblockierstellung ein Verschieben des Stellelements aus seiner Sperrstellung in seine Rückzugsstellung gegen Federkraft gestattet. Die Kurvenscheibe kann dabei an dem Schließzylinderkern des Schließzylinders zur gemeinsamen Drehung mit diesem angebracht sein.The control element can, as already indicated, by a Blocking device can be blocked in its locked position be, the blocking device preferably based a commercially available locking cylinder is built. Here can the blocking device with a rotatable cam be executed, which in a blocking position the blocking device from evading the actuating element blocked in its retracted position and in a non-blocking position, a displacement of the actuating element from its locked position to its retracted position permitted against spring force. The cam can be on the lock cylinder core of the lock cylinder for common Rotation with this be appropriate.

Im Hinblick auf einen einfachen und preisgünstigen Aufbau des Schlosses ist vorgesehen, daß der Schließzylinder in einem Halteteil wenigstens teilweise aufgenommen ist, an welchem die Führungsbahn für das Riegelelement und/oder das Stellelement ausgebildet ist.With regard to a simple and inexpensive construction the lock is provided that the lock cylinder in a holding part is at least partially received which the guideway for the locking element and / or that Control element is formed.

Der Schloßkörper kann mit einem rohrförmigen Gehäuse ausgeführt sein und innerhalb dieses rohrförmigen Gehäuses ein Halteteil aufweisen, in welchem die Führungsbahn für das Riegelelement und/oder das Stellelement ausgebildet ist. Da bei Anwendung des Erfindungsprinzips keine wesentlichen Reaktionskräfte aus starken Auszugskräften auf das Stellelement und die Blockiereinrichtung einwirken, genügt es, das rohrförmige Gehäuse aus hochfestem Werkstoff, z.B. Stahlblech, herzustellen. Andererseits ist es unschädlich, wenn der Halteteil mit der Führungsbahn für das Riegelelement und/oder das Stellelement sowie ggf. mit einer Aufnahmekammer für den Schließdorn und mit einer Lagerung für die Blockiereinrichtung aus Kunststoff, etwa im Gieß- oder Spritzgießverfahren oder aus Zinkdruckguß hergestellt ist, weil auch der Halteteil nur geringen Reaktionskräften unterliegt. Es ist vorteilhaft, wenn die Aufnahmekammer für den Schließdorn ebenfalls in dem Halteteil ausgebildet wird, weil dann die Teilezahl die zum Montieren des Schlosses notwendig ist, verringert wird. Die Führungsbahn mündet dann in die Aufnahmekammer ein.The lock body can have a tubular housing be executed and within this tubular housing have a holding part in which the guideway for the Locking element and / or the actuating element is formed. Because when applying the principle of the invention no essential Reaction forces from strong pull-out forces on the actuator and the blocking device act, it is sufficient the tubular housing made of high-strength material, e.g. Steel sheet. On the other hand, it is harmless if the holding part with the guide track for the locking element and / or the control element and possibly with a Holding chamber for the locking pin and with a bearing for the blocking device made of plastic, for example in casting or Injection molding process or made of die-cast zinc is because the holding part only has low reaction forces subject to. It is advantageous if the receiving chamber for the locking pin is also formed in the holding part, because then the number of parts for assembling the lock is necessary is reduced. The guideway then opens into the receiving chamber.

Das Riegelement soll bei zurückgezogenem Schließdorn in einer Stellung gehalten sein, in der es das Wiedereinführen des Schließdorns ohne besondere Vorbereitungsmaßnahmen erlaubt. Es ist deshalb vorgesehen, daß das Riegelelement in seiner Verriegelungsstellung gegen Übertritt aus seiner Führungsbahn in die Schließdornaufnahme auch dann gesichert ist, wenn der Schließdorn aus der Schließdornaufnahme zurückgezogen ist. Diese Sicherung läßt sich leicht dadurch erreichen, daß an einem der Schließdornaufnahme nahen Ende der Führungsbahn eine Führungsbahnverengung vorgesehen ist. Es können auch Anschlagmittel zum Erreichen dieser Sicherung verwendet werden.The locking element should be in when the locking pin is retracted be held in a position in which it is reintroduced of the closing mandrel without special preparation measures allowed. It is therefore provided that the locking element in its locking position against transfer from its The guideway is then also secured in the locking pin holder is when the striker comes out of the striker holder withdrawn. This backup can be done easily achieve that at an end close to the locking pin holder the guideway is provided with a narrowing of the guideway. There may also be slings to achieve this security be used.

Das Erfindungsprinzip ist grundsätzlich bei allen bekannten Schlössern anwendbar, bei denen ein oder mehrere Schließdorne in jeweils eine Schließdornaufnahme eingeführt und dort verriegelt werden sollen. Besonders interessant ist die Anwendung des Erfindungsprinzips bei einem Bügelschloß mit einem Schloßbügel, der an beiden Enden seiner Bügelschenkel je einen Schließdorn zur Aufnahme in je einer Schließdornaufnahme eines Schloßkörpers aufweist. Dabei kann der Schloßkörper, wie bei Bügelschlössern zur Zweiradsicherung üblich, in bezug auf eine Symmetrieebene des Schlosses symmetrisch gestaltet sein, wobei eine Blockiereinrichtung in einem mittleren Bereich zwischen den beiden Schließdornaufnahmen angeordnet und den beiden Schließdornaufnahmen gemeinsam zugeordnet sein kann. Bei einer solchen Schloßgestaltung wird empfohlen, daß die Blockiereinrichtung in einer Blockiereinrichtungshaltekammer innerhalb des Schloßkörpers untergebracht ist, welche durch zwei in der Symmetrieebene zusammenstoßende Halteteile begrenzt ist und wobei von diesen beiden Halteteilen jeder eine Führungsbahn für ein jeweils zugehöriges Riegelelement und/oder Stellelement bildet.The principle of the invention is basically known in all Locks applicable where one or more locking pins inserted in a locking pin holder and should be locked there. It is particularly interesting Application of the principle of the invention with a padlock a lock shackle on both ends of its shackle legs One locking pin each for insertion in one locking pin holder has a lock body. The Lock body, as with padlocks for securing two-wheelers usual, with respect to a plane of symmetry of the lock be designed symmetrically, with a blocking device in a middle area between the two mandrel holders arranged and the two locking pin receptacles can be assigned together. With such a lock design it is recommended that the blocking device in a blocking device holding chamber within the lock body which is accommodated by two in the plane of symmetry colliding holding parts is limited and each of these two holding parts has a guideway for an associated locking element and / or adjusting element forms.

Auf diese Weise benötigt man zur Lagerung der bewegten Eingerichteteile nur zwei Halteteile; diese Halteteile können mit identischer Form ausgeführt werden, was zu einer weiteren Senkung der Herstellungskosten führt. Die Halteteile können aus Kunststoff ausgeführt werden und brauchen, da sie keine wesentlichen Kräfte aufzunehmen haben, nicht starkwandig ausgeführt zu werden. Es genügt vielmehr, die Kunststoffverteilung in den einzelnen Halteteilen so zu wählen, daß einerseits die Führungsbahnen für das Verriegelungselement und das Stellelement, die Aufnahme für den Schließdorn und die Aufnahme für die Blockiereinrichtung bereitgestellt sind und andererseits Anlagekanten oder Anlageflächen für die positionsgerechte Lagerung der Halteteile in einem Außengehäuse des Schloßkörpers zur Verfügung stehen.In this way you need to store the moving Furnished parts only two holding parts; these holding parts can be carried out with an identical shape, resulting in a further reducing manufacturing costs. The holding parts can be made of plastic and need since they have no essential powers to absorb to be executed with thick walls. Rather, it is sufficient that Plastic distribution in the individual holding parts choose that on the one hand the guideways for the locking element and the actuator, the recording for the Locking pin and the holder for the blocking device are provided and on the other hand system edges or Contact surfaces for the correct positioning of the holding parts in an outer housing of the lock body stand.

Der Schloßkörper kann dabei ein rohrförmiges Gehäuse von rundem oder polygonalem, insbesondere rechteckigem, Querschnitt aufweisen, welches den Abstand zwischen den beiden Schließdornaufnahmen überbrückt in einem Mittelbereich die Blockiereinrichtung aufnimmt und über die Schließdornaufnahme nur soweit übersteht, als für die Bildung der Schließdornaufnahmekammern erforderlich ist. Die Halteteile können von einem oder von beiden Enden her in das rohrförmige Gehäuse eingeschoben werden, nachdem man vorher an beiden Halteteilen die jeweils zugehörigen Eingerichteteile, nämlich Verriegelungselement, Stellelement, Vorspannfedern und ggf. Verrastungsplatten vormontiert hat. The lock body can be a tubular housing round or polygonal, especially rectangular, Have cross section, which is the distance between the the two locking pin adapters bridged in a central area the blocking device receives and over the The locking pin holder only survives as far as for education the locking pin receiving chambers is required. The Holding parts can be inserted into the from one or both ends tubular housing can be inserted after going before on both holding parts, the corresponding set-up parts, namely locking element, actuator, biasing springs and possibly pre-assembled locking plates.

Die Blockiereinrichtung wird im Vorlauf zu der einen oder anderen vormontierten Einheit in das rohrförmige Gehäuse eingeschoben und sitzt nach Einschieben der beiden vormontierten Einheiten zwischen diesen in der richtigen Position fest. Man braucht dann nur noch die Halteteile in ihrer eingeschobenen Position zu sichern, etwa durch Sicherungsstifte, die in fluchtende Bohrungen des rohrförmigen Gehäuses und der Halteteile eingeschlagen oder eingedrückt werden. Der Materialaufwand und das Gewicht des Schloßkörpers bleiben relativ gering, ohne daß die Sicherheitsfunktion dadurch beeinträchtigt wird. Das optische Erscheinungsbild wird im wesentlichen nur durch die Form des Gehäuses, insbesondere rohrförmigen Gehäuses, und durch die Form des Bügels bestimmt, d.h. durch zwei Teile, denen man mit geringem Aufwand eine vom Aussehen her günstige Oberflächengestaltung verleihen kann.The blocking device becomes one or the other in advance other pre-assembled unit in the tubular housing inserted and sits after inserting the two pre-assembled Units between these in the correct Position. Then you only need the holding parts in secure their retracted position, for example by Locking pins inserted into aligned holes in the tubular Enclosed housing and the holding parts or be pushed in. The cost of materials and the weight of the Lock body remain relatively small without the security function is affected. The optical Appearance is essentially only due to the shape of the Housing, in particular tubular housing, and by the Form of the bracket determined, i.e. by two parts that one a surface design that is favorable in appearance with little effort can lend.

Die Blockiereinrichtung läßt sich in ergonomisch günstiger Weise unterbringen. Der Schlüsseleintrittsschlitz kann etwa bei rechteckigem Querschnitt des Gehäuserohrs an jeder Seitenfläche des Gehäuserohrs angebracht werden. Aus ergonomischen und herstellungstechnischen Gesichtspunkten wird es freilich bevorzugt, den Schlüsseleintrittsschlitz im Bereich einer von dem Schloßbügelscheitel ferngelegenen Gehäusefläche anzubringen. Die Gestaltung der Gehäuseteile aus leicht verformbarem Material, insbesondere Kunststoff, erlaubt es, an diesen Halteteilen beliebige Kammerbegrenzungsflächen für die Bildung einer den Schließzylinder aufnehmenden Kammer anzuformen, so daß man bei der Auswahl der Schließzylinder eine große Wahl innerhalb des handelsüblichen Sortiments von Schließzylindern hat.The blocking device can be ergonomically cheaper House way. The key entry slot can be about with a rectangular cross section of the housing tube on each Side surface of the housing tube are attached. From ergonomic and manufacturing aspects it is of course preferred to use the key entry slot in the Area of a remote from the top of the lock bracket Attach the housing surface. The design of the housing parts made of easily deformable material, especially plastic, allows any chamber boundary surfaces on these holding parts for the formation of the lock cylinder to form the receiving chamber so that you can choose the lock cylinder is a great choice within the commercial Range of locking cylinders.

In den Figuren 1-5 ist ein Schloßbügel mit 10 bezeichnet. Die beiden Bügelschenkel 12 des Schloßbügels sind mit je einem Schließdorn 14 ausgeführt. Die Schließdorne 14 sind in einem Schloßkörper aufgenommen, der ganz allgemein mit 16 bezeichnet ist. Der Schloßkörper 16 umfaßt ein rohrförmiges Schloßkörpergehäuse 18, das - wie aus Figuren 4 und 5 ersichtlich - Rechtecksquerschnitt besitzt. In das rohrförmige Schloßkörpergehäuse 18 ist von beiden Enden je ein Halteteil 20 eingeschoben. Die beiden Halteteile 20 und ihre im folgenden zu beschreibenden Eingerichteteile sind miteinander identisch, so daß die Beschreibung eines einzigen dieser Halteteile genügt. Das Halteteil 20 ist als ein Kunststoffspritzgußkörper ausgeführt, dessen Mittelabschnitt-wie in Figur 4 dargestellt - einen im wesentlichen pokalförmigen Querschnitt besitzt. In dem Mittelabschnitt ist eine nach oben offene Fühgrungsbahn 22 von teilkreisförmigem Querschnitt eingeformt. In dieser Führungsbahn 22 ist eine Verriegelungskugel 24 geführt. Die Führungskugel 24 ist zum Eingriff in eine Schließfläche 26 des Schließdorns 14 ausgebildet. An dem schließdornfernen Ende der Verriegelungskugel 24 liegt ein Stellelement 28 an. Dieses Stellelement 28 weist eine Führungsplatte 28a und einen Stellschenkel 28b auf. Der Stellschenkel 28b liegt mit seinem schließdornnahen Ende an der Verriegelungskugel 24 an. Die Führungsplatte 28a ist an dem Halteteil 20 im oberen Bereich des Pokalprofils oberhalb der Führungsbahn 22 in Pfeilrichtung 30 verschiebbar geführt. An dem schließdornfernen Ende des Stellschenkels 28b greift eine Schraubendruckfeder 32 an, die am Gehäuse 34a eines insgesamt mit 34 bezeichneten Schließzylinders abgestützt ist. Die Führungsbahn 22 erstreckt sich im Bereich der Verriegelungskugel 24 in ihrem Querschnitt über mehr als 180° der Verriegelungskugel 24, so daß auch dann noch, wenn unter normalen Betriebsumständen die Verriegelungskugel 24 in die Schließfläche 26 des Schließdorns 14 eingreift, die Verriegelungskugel 24 in Richtung des Doppelpfeils 38 kein wesentliches Spiel gegenüber der Führungsbahn 22 hat. Der Doppelpfeil 38 repräsentiert die Schließdorneinführungsrichtung bzw. Schließdornauszugsrichtung des Schließdorns 12 gegenüber dem Schloßkörper 16.In Figures 1-5, a lock bracket is designated 10. The two shackle legs 12 of the lock shackle are each with a locking pin 14 executed. The locking pins 14 are in a lock body, which is generally 16 is designated. The lock body 16 comprises a tubular one Lock body housing 18, which - as can be seen from Figures 4 and 5 - Has a rectangular cross-section. In the tubular Lock body housing 18 is a holding part from both ends 20 inserted. The two holding parts 20 and their in the following Furnishing parts to be described are together identical, so the description of a single one of these Holding parts are sufficient. The holding part 20 is as a plastic injection molded body executed, the middle section - as in Figure 4 shown - an essentially cup-shaped Cross section. In the middle section is one after Fühgrungsbahn 22 open at the top of part-circular cross-section molded. In this guideway 22 is one Locking ball 24 out. The guide ball 24 is for Engagement in a closing surface 26 of the locking pin 14 is formed. At the end of the locking ball away from the mandrel 24 is an actuator 28. This actuator 28 has a guide plate 28a and an adjusting leg 28b on. The adjusting leg 28b lies with its close to the closing mandrel End on the locking ball 24. The guide plate 28a is on the holding part 20 in the upper region of the cup profile Slidable above the guideway 22 in the direction of arrow 30 guided. At the end of the adjusting leg remote from the mandrel 28b attacks a helical compression spring 32 which on Housing 34a of a locking cylinder, designated overall by 34 is supported. The guideway 22 extends in the area of the locking ball 24 in its cross section over more than 180 ° of the locking ball 24, so that too when the locking ball is under normal operating conditions 24 in the closing surface 26 of the closing mandrel 14 engages the locking ball 24 in the direction of Double arrow 38 no essential game against the guideway 22 has. The double arrow 38 represents the Mandrel insertion direction or mandrel extension direction of the locking pin 12 relative to the lock body 16.

Der Schließzylinder 34a ist mit einem Schließzylinderkern 34b ausgeführt und beruht auf dem Prinzip von schlüsselbrustgesteuerten federbelasteten Zuhaltungsstiftpaaren. Der Schlüssel 34c kann von unten durch einen Schlitz 40 des rohrförmigen Gehäuses 18 in den Schließzylinder eingeführt werden, so daß der Schließzylinderkern 34b gedreht werden kann. An dem oberen Ende des Schließzylinderkerns 34b ist eine Kurvenscheibe 44 angebracht, deren Form insbesondere in Figur 3 zu erkennen ist. An dieser Kurvenscheibe liegen gemäß Figur 3 die Führungsplatten 28a an und zwar im Bereich von radial vorspringenden Nocken 44a. Diese Nocken 44a sind so bemessen, daß in der Zuordnung gemäß Figur 2 die Verriegelungskugeln 24 durch die Stellelemente 28 in Eingriff mit den jeweiligen Schließflächen 26 gehalten werden.The lock cylinder 34a has a lock cylinder core 34b executed and based on the principle of key chest controlled spring-loaded tumbler pin pairs. Of the Key 34c can be viewed from below through a slot 40 of the tubular housing 18 inserted into the lock cylinder so that the lock cylinder core 34b is rotated can. At the upper end of the lock cylinder core 34b a cam 44 attached, the shape of which in particular Figure 3 can be seen. Lie on this cam according to Figure 3 on the guide plates 28a in the area of radially projecting cams 44a. These cams are 44a dimensioned so that in the assignment according to Figure 2, the locking balls 24 engaged by the actuating elements 28 are held with the respective closing surfaces 26.

Da, wie schon ausgeführt, die Verriegelungskugeln 24 auch in dieser Stellung noch im wesentlichen spielfrei in der Richtung des Doppelpfeils 38 durch die jeweilige Führungsbahn 22 geführt sind, hat der Schließdorn 14 bei normaler Belastung in Auszugsrichtung gemäß 38 im wesentlichen kein Spiel gegenüber der Schließdornaufnahme 46 des jeweiligen Halteteils 20, in der er aufgenommen ist. Nur wenn, wie in Figur 1 dargestellt, eine sehr große Auszugskraft P auf den Schließdorn 14 ausgeübt wird, z.B. in der Größenordnung von 20 kN, so tritt eine elastische Verformung der Führungsbahn 22 auf, indem sich diese im Bereich der oberen Öffnung des Pokalprofils gemäß Figur 4 aufspreizt. Dann kann die Verriegelungskugel 24 in Richtung der Auszugskraft P nach oben durch die Schließfläche 26 mitgenommen werden. Nun ist, wie insbesondere aus Figuren 1,2 und 3 zu ersehen, am oberen Ende der Schließdornaufnahme 46 eine Widerlagerplatte 48 angeordnet, welche gemäß Figur 3 durch das rohrförmige Gehäuse 18 und das Halteteil 20 positioniert ist. Diese Widerlagerplatte 48 weist eine schlüssellochförmige Öffnung 50 auf mit einer Durchtrittsöffnung 50a für den Schließdorn 14 und einer Erweiterung 50b. Die Erweiterung 50b steht, wie aus Figuren 1 und 2 ersichtlich, in Längsrichtung des Schließdorns 14 der Kugel 24 gegenüber. Wenn die große Auszugskraft P ausgeübt wird, so versucht die Verriegelungskugel 24 durch die sich zwischen der Schließfläche 26 und der Verriegelungskugel 24 eintretende Nockenwirkung zunächst nach links auszuweichen und belastet damit das Stellelement 28. Da das Stellelement 28 durch die Kurvenscheibe 44 starr abgestützt ist, wird aber die Verriegelungskugel 24 nicht in Richtung der Führungsbahn 22 seitlich verdrängt, sondern unter Deformation der Führungsbahn, d.h. des Pokalprofils gemäß Figur 4, eine kurze Strecke nach oben in Richtung der Kraft P mitgenommen. Dabei wird der Zustand gemäß Figur 1 erreicht, d.h. ein Zustand, bei dem die Kugel in die Erweiterung 50b der schlüssellochförmigen Öffnung 50 eintritt. Die Bemessung der Erweiterung 50b ist nun so getroffen, daß dann, wenn die Verriegelungskugel 24 einmal in den Bereich mit den unteren Kanten der Erweiterung 50b eingetreten ist, eine Selbsthemmung der Verriegelungskugel 24 zwischen der Schließfläche 26 und diesen Kanten der Erweiterung 50b eintritt. Dieser Zustand ist in Figur 1 dargestellt. Die Selbsthemmung der Verriegelungskugel 24 zwischen der Schließfläche 26 und der Erweiterung 50b läßt sich leicht durch entsprechende Bemessung der Tiefe der Schließfläche 26 und der Form und Größe der Erweiterung 50b einstellen. Selbsthemmung soll besagen, daß - wenn die Verriegelungskugel 24 einmal Eingriff mit der unteren Begrenzungskante der Erweiterung 50b gefunden hat und gleichzeitig noch an der Schließfläche 26 anliegt, die Kugel 24 nicht mehr das Bestreben hat, in Richtung des Doppelpfeils 30 nach links auszuweichen, sondern sich zwischen der Schließfläche 26 und der unteren Kante der Erweiterung 50b selbsthaltend einklemmt. Es wird also keine weitere Kraft auf das Stellelement 28 ausgeübt, welche den Schließzylinder 34 über seine Tragfähigkeit hin aus belasten könnte. Die bis zum Eingriff der Verriegelungskugel 24 in die Erweiterung 50b auftretende Stützkraft des Stellelements 28 auf die Verriegelungskugel 24 kann durch entsprechende Dimensionierung und Materialwahl so bemessen werden, daß eine Beschädigung des Schließzylinders 34 nicht eintreten kann und auch nicht der übrigen an der Abstützung beteiligten Komponenten. Wenn die Kraft P aufhört, so kehrt die Verriegelungskugel 24 aufgrund der elastischen Vorspannung, welche die Führungsbahn 22 bei der Aufwärtsbewegung der Verriegelungskugel 24 bis zum Eingriff mit der Erweiterung 50b erfahren hat, in die Stellung gemäß Figur 2 zurück.Since, as already stated, the locking balls 24 also in this position is still essentially free of play in the direction of the double arrow 38 through the respective guideway 22 are guided, the locking pin 14 has a normal load essentially no play in the pull-out direction according to FIG. 38 opposite the locking pin receptacle 46 of the respective holding part 20 in which he is included. Only if, as in figure 1, a very large pull-out force P on the Closing pin 14 is exerted, e.g. on the order of 20 kN, elastic deformation of the guideway 22 occurs by placing them in the area of the upper opening of the Cup profile spreads according to Figure 4. Then the locking ball 24 in the direction of the pull-out force P upwards be taken along by the closing surface 26. Now is, as can be seen in particular from Figures 1, 2 and 3, on upper end of the locking pin receptacle 46 an abutment plate 48 arranged, which according to Figure 3 by the tubular Housing 18 and the holding part 20 is positioned. This Abutment plate 48 has a keyhole-shaped opening 50 on with a passage opening 50a for the closing mandrel 14 and an extension 50b. The extension 50b is as can be seen from Figures 1 and 2, in the longitudinal direction of the Locking pin 14 of the ball 24 opposite. If the big one Pulling force P is exerted, the locking ball tries 24 through which between the closing surface 26 and the locking ball 24 occurring cam action initially dodge to the left and thus loads the control element 28. Since the control element 28 is rigid due to the cam 44 is supported, but the locking ball 24 is not in Displaced sideways direction 22, but under deformation of the guideway, i.e. of the cup profile 4, a short distance up in the direction of Force P taken. The state according to FIG. 1 reached, i.e. a condition where the bullet is in the extension 50b of the keyhole-shaped opening 50 occurs. The dimensioning of extension 50b is now such that then when the locking ball 24 once in the area with the lower edges of extension 50b a self-locking of the locking ball 24 between the Closing surface 26 and these edges of extension 50b entry. This state is shown in Figure 1. The Self-locking of the locking ball 24 between the Closing surface 26 and extension 50b can be easily by appropriate dimensioning of the depth of the closing surface 26 and adjust the shape and size of the extension 50b. Self-locking is said to say that - if the locking ball 24 one time engagement with the lower boundary edge the extension 50b has found and still on the closing surface 26 abuts, the ball 24 no longer Has endeavored in the direction of the double arrow 30 to the left to avoid, but between the closing surface 26 and the lower edge of the extension 50b clamped. So there is no further force on the actuator 28 exercised over the locking cylinder 34 could strain its load-bearing capacity. The by Engagement of the locking ball 24 in the extension 50b occurring support force of the actuator 28 on the locking ball 24 can be dimensioned accordingly and choice of materials are dimensioned so that a Damage to the lock cylinder 34 cannot occur and also not the rest of the people involved in the support Components. When the force P ceases, the locking ball returns 24 due to the elastic preload, which the guide track 22 during the upward movement of the Locking ball 24 until it engages with the extension 50b has experienced, back to the position shown in Figure 2.

Die Auszugskraft P, die - wie gesagt - zur Verklemmung der Verriegelungskugel 24 zwischen der Schließfläche 26 und der Erweiterung 50b führt, ergibt eine Reaktionskraft in Pfeilrichtung 52 der Figur 1 auf die Widerlagerplatte 48. Diese Reaktionskraft wird aber im wesentlichen auf den Schließdorn 14 übertragen, der ja mit der Durchtrittsöffnung 50a der Widerlagerplatte 48 in Eingriff steht. Es wird also auch durch die Querkraft 52 keine wesentliche Belastung des Schloßeingerichtes erzeugt.The pull-out force P, which - as I said - to jam the Locking ball 24 between the closing surface 26 and the Extension 50b results in a reaction force in Direction of arrow 52 of FIG. 1 onto abutment plate 48. This reaction force is essentially due to the Locking pin 14 transmitted, yes with the passage opening 50a of the abutment plate 48 is engaged. So it will also by the transverse force 52 no significant load on the Castle furnishings generated.

Wenn das Schloß geöffnet werden soll, wird der Schließzylinderkern 34b mittels des Schlüssels 34c um 90° gedreht. Die Stellelemente 28 liegen dann an der Kurvenscheibe 44 im Bereich von Ausnehmungen 44b an und können gegen die Wirkung der Schraubendruckfedern 32 zurückweichen. Wenn nunmehr der Schloßbügel 10 aus dem Schloßkörper ausgezogen werden soll, so tritt wieder eine Nockenwirkung zwischen der Schließfläche 26 und der Verriegelungskugeln 24 ein. Die Verriegelungskugeln 24 weichen nunmehr aber nicht in Pfeilrichtung 38 nach oben aus, weil sie leichter in Pfeilrichtung 30 nach links ausweichen können. Die Kugeln 24 kommen also gar nicht erst in Eingriff mit der Erweiterung 50b und können deshalb unter Kompression der jeweiligen Schraubendruckfedern 32 soweit in Richtung des Pfeils 30 nach links ausweichen, bis die Verriegelungskugel 24 völlig aus der Schließfläche 26 ausgetaucht und der Schließdorn 14 vollständig ausgezogen werden kann. Notwendig ist dabei, daß die Verformungselastizität der Führungsbahn 22 und die Federkraft der Schraubendruckfeder 32 richtig aufeinander abgestimmt sind, um der Verriegelungskugel 24 ein Ausweichen in Pfeilrichtung 30 vor einem Ausweichen nach oben in Pfeilrichtung 38 zu ermöglichen.When the lock is to be opened, the lock cylinder core 34b rotated by 90 ° by means of the key 34c. The actuators 28 are then on the cam 44 in Range of recesses 44b and can against the effect the helical compression springs 32 retreat. If now the Lock shackle 10 is to be pulled out of the lock body, a cam effect occurs again between the closing surface 26 and the locking balls 24 a. The locking balls 24 now do not move in the direction of the arrow 38 upwards because they are easier in the direction of the arrow 30 can dodge to the left. The balls 24 come not in the first place with the extension 50b and can therefore under compression of the respective helical compression springs 32 so far in the direction of arrow 30 to the left dodge until the locking ball 24 completely out of the Closing surface 26 dipped and the locking pin 14 completely can be pulled out. It is necessary that the Deformation elasticity of the guideway 22 and the spring force the helical compression spring 32 properly matched are in order to avoid the locking ball 24 Arrow direction 30 before evading upwards in To allow arrow direction 38.

Die Form der Schließfläche 26, der Durchmesser der Verriegelungskugel 24 und die Vorspannung der Schraubendruckfeder 32 werden so aufeinander abgestimmt, daß bei einem normalen Öffnen des Schlosses nach vorheriger Entblockierung des Schließzylinders 34 der Schloßbügel 10 mit einer geringen Auszugskraft gelöst werden kann, wobei andererseits diese Auszugskraft nicht zu klein sein soll, damit nicht ein unbeabsichtigtes Herausfallen des Schloßbügels aus dem Schloßkörper eintreten kann.The shape of the closing surface 26, the diameter of the locking ball 24 and the preload of the helical compression spring 32 are coordinated so that one normal opening of the lock after unblocking of the lock cylinder 34 of the lock bracket 10 with a small Extraction can be solved, on the other hand this pull-out force should not be too small, so not one unintentional falling out of the lock bracket from the Lock body can enter.

Das Wiedereinführen des Schließdorns 14 in die Schließdornaufnahme 46 ist auch nur dann möglich, wenn die Kurvenscheibe 44 in die vorbeschriebene Stellung verdreht ist, in welcher die Stellelemente 28 in Richtung auf den Schließzylinder 34 zurückweichen können. Dann kann der Schließdorn 14 beim Einschieben in die Schließdornaufnahme die Verriegelungskugel 24 zurückschieben, bis diese endlich in die Schließfläche 26 unter der Wirkung der Schraubendruckfeder 32 einfallen kann. Der Schlüssel 34c kann erst wieder in die Blockierstellung verdreht werden, nachdem die Schließfläche 26 in Flucht mit der Verriegelungskugel 24 getreten ist. Erst nach dieser Verdrehung kann entsprechend den Eigenschaften eines Schließzylinders mit federbelasteten Zuhaltungsstiftpaaren der Schlüssel abgezogen werden, so daß ein vorzeitiges Abziehen des Schlüssels bei nicht verriegeltem und gesichertem Schloß unmöglich ist. Der Benutzer hat deshalb, wenn er den Schlüssel nach dem Einstecken des Schließdorns 14 gezogen hat, die Gewissheit, daß er den Schließdorn weit genug eingeschoben und damit verriegelt und gesichert hat. The reinsertion of the locking pin 14 into the locking pin receptacle 46 is only possible if the cam 44 is rotated into the position described above, in which the actuators 28 towards the lock cylinder 34 can retreat. Then the closing pin 14 the locking ball when inserted into the locking pin holder 24 push it back until it is finally in the Closing surface 26 under the action of the helical compression spring 32 can come up with. The key 34c can only be reinserted into the Blocked position are rotated after the closing surface 26th is in alignment with the locking ball 24. First after this twisting can according to the properties a locking cylinder with spring-loaded tumbler pin pairs the key will be removed so that an early Remove the key with the unlocked and secured lock is impossible. The user therefore has if he has the key after inserting the locking pin 14 has pulled the certainty that he has the mandrel wide inserted enough and thus locked and secured.

Zu beachten ist, daß die Widerlagerplatte 48 neben der Widerlagerfunktion auch eine Sicherungsfunktion erfüllen kann, indem sie die Zugänglichkeit des Schloßeingerichtes durch Aufbohren des Gehäuses und anschließendes Einführen von Eingriffselementen erschwert; außerdem versteift sie das Schloßgehäuse gegen Ausreißkräfte.It should be noted that the abutment plate 48 next to the Abutment function also perform a securing function can by making the accessibility of the castle interior by drilling out the housing and then inserting it complicated by engaging elements; it also stiffens the lock housing against pull-out forces.

Zu bemerken ist weiter, daß die Halteteile 20 formgleich ausgebildet sein können. Gleichwohl können die Formteile, wie aus Figur 4 ersichtlich, mit Paßstücken ausgeführt sein, die ein Zusammenstecken ermöglichen. Man erkennt in der Figur 4 einen Zapfen 60 und eine Zapfenaufnahme 62. Wenn die beiden formgleichen Halteteile innerhalb des Schloßgehäuses 18 zusammengesteckt werden, so findet der Zapfen des einen Halteteils 20 in die Zapfenaufnahme 62 des anderen Halteelements. Die Schließdornaufnahmen 46 sind Bestandteil des jeweiligen Halteteils 20. Die einander zugekehrten Enden der Halteteile 20 bilden auch eine Aufnahme 64 für den Schließzylinder, so daß dieser drehfest in dem Schloßkörper 16 gehalten ist. Die Festlegung der Halteteile 20 in Längsrichtung des rohrförmigen Schloßgehäuses 18 erfolgt durch Verstiftung bei 66. Man erkennt aus den Figuren 1-5, daß die Halteteile 20 dünnwandig ausgebildet sind, so daß sie im wesentlichen nur die innerhalb der Halteteile notwendigen Funktionsflächen festlegen. Die formschlüssige Aufnahme der Halteteile in dem rechteckförmigen Profil des rohrförmigen Gehäuses 18 erfolgt in den oberen Ecken 68 durch die Ränder des Pokalprofils und im Bodenbereich des Gehäuses durch den Stiel 70 des Pokalprofils. Somit kann die Elastizität der Führungsbahn 22 gegen Ausweichen der Verriegelungskugel 24 in Pfeilrichtung 38 durch die Abstützung der Ränder des Pokalprofils an den Seitenwänden des rohrförmigen Gehäuses eingestellt werden. It should also be noted that the holding parts 20 have the same shape can be trained. Nevertheless, the molded parts, as can be seen from FIG. 4, be designed with adapters, that allow you to plug them together. You can see in the Figure 4 a pin 60 and a pin receptacle 62. If the two identical holding parts within the lock housing 18 are put together, so the tenon of one finds Holding part 20 in the pin receptacle 62 of the other holding element. The locking pin receptacles 46 are part of the respective holding part 20. The facing ends the holding parts 20 also form a receptacle 64 for the Lock cylinder, so that it rotatably in the lock body 16 is held. The fixing of the holding parts 20 in the longitudinal direction of the tubular lock housing 18 is carried out by Pinning at 66. It can be seen from Figures 1-5 that the Holding parts 20 are thin-walled, so that they are in essential only those necessary within the holding parts Define functional areas. The positive reception of the Holding parts in the rectangular profile of the tubular Housing 18 is in the upper corners 68 through the edges of the cup profile and in the bottom area of the housing by the Stem 70 of the cup profile. Thus, the elasticity of the Guide track 22 to prevent locking ball 24 from evading in the direction of arrow 38 by supporting the edges of the Cup profile on the side walls of the tubular housing can be set.

Die Anordnung des Schlüsseleingriffsschlitzes 40 an der unteren Gehäusewand erleichtert die Handhabung des Schlosses.The arrangement of the key engagement slot 40 on the lower housing wall facilitates the handling of the Castle.

Es muß natürlich dafür gesorgt sein, daß bei zurückgezogenem Schließdorn 14 die Verriegelungskugel 24 nicht in die Schließdornaufnahme 46 hineinfallen kann. Dies kann durch eine schließdornnahe Verengung der Führungsbahn 22 oder durch andere Anschlagmittel erfolgen.Of course, it must be ensured that when withdrawn Locking pin 14, the locking ball 24 is not in the Locking pin receptacle 46 can fall into it. This can be done by a narrowing of the guideway 22 near the mandrel or done by other slings.
