On the threaded spindle can be screwed a threaded casing (5), by means of which the T-shaped tube casing and the upper counter bearing can be fixed in a distance position to the lower counter bearing.

Description

Die vorliegende Erfindung betrifft eine Schutzgeländer-Zwinge, insbesondere eine Schutzgeländer-Zwinge, die zur Schaffung provisorischer Schutzgeländer in Rohbauten eingesetzt werden kann.The present invention relates to a guardrail clamp, in particular a guardrail clamp that can be used to create provisional guardrails in unfinished buildings.

Es ist bekannt, in Rohbauten Treppen und ebene Plattformen, wie zum Beispiel Balkone, mit Vorrichtungen zu versehen, die Halterungen für Geländerbretter aufweisen. Die in die Halterungen eingefügten Geländerbretter dienen als provisorischer Schutz. Insbesondere ist der Einsatz von Schutzgeländer-Zwingen bekannt, die schnell und unkompliziert an einem Bauteil angebracht werden können, weil oberes und unteres Widerlager gegeneinander verschiebbar sind (zum Beispiel: Prospekt Nr. 28 der Firma Müller & Baum).It is known to provide stairs and level platforms, such as balconies, in structures with devices which have brackets for railing boards. The railing boards inserted into the brackets serve as provisional protection. In particular, the use of protective railing clamps is known, which can be quickly and easily attached to a component because the upper and lower abutments can be moved against each other (for example: brochure no. 28 from Müller & Baum).

Als wesentlicher Nachteil der bekannten Schutzgeländer-Zwingen erweist sich jedoch die Tatsache, daß sie entweder nur an Treppen oder nur an ebenen Plattformen angebracht werden können.A major disadvantage of the known guardrail clamps, however, is the fact that they can only be attached to stairs or only to flat platforms.

Der vorliegenden Erfindung liegt das Problem zugrunde, eine Schutzgeländer-Zwinge zu schaffen, die sowohl zur Sicherung von Treppen, als auch zur Sicherung von ebenen Plattformen eingesetzt werden kann und die auftretenden Verkehrslasten aufnehmen kann.The present invention is based on the problem of creating a protective railing clamp which can be used both for securing stairs and for securing flat platforms and can absorb the traffic loads that occur.

Dieses Problem wird gelöst durch eine Schutzgeländer-Zwinge mit den kennzeichnenden Merkmalen des Anspruchs 1, deren wesentliche Eigenschaft die Verschwenkbarkeit des unteren Widerlagers gegenüber dem oberen Widerlager um die Achse des oberen Widerlagers ist. Die beiden Widerlager können so gegeneinander verschwenkt werden, daß das untere Widerlager unter der schrägen Unterseite einer Treppe anliegt, während gleichzeitig das obere Widerlager auf einer Treppenstufe aufliegt. Dabei kann das untere Widerlager sowohl nach links als auch nach rechts geschwenkt werden, so daß ein linksseitiges oder rechtsseitiges Anschlagen der Schutzgeländer-Zwinge möglich ist. Es kann aber auch in eine unverschwenkte Position gebracht werden, so daß die Anbringung an einer ebenen Plattform ermöglicht wird.This problem is solved by a guardrail clamp with the characterizing features of claim 1, the essential property of which is the pivotability of the lower abutment relative to the upper abutment about the axis of the upper abutment. The two abutments can be pivoted against each other so that the lower abutment under the sloping underside of a staircase, while the upper abutment rests on a step. The lower abutment can be swiveled both to the left and to the right, so that the guard rail clamp can be attached on the left or right side. However, it can also be brought into a non-pivoted position so that it can be attached to a flat platform.

Nach einer bevorzugten Ausgestaltung der vorliegenden Erfindung erfolgt die Verschiebung der Widerlager gegeneinander vermittels einer Rohrhülse, die auf einer Gewindespindel axial verschiebbar ist.According to a preferred embodiment of the present invention, the abutments are displaced relative to one another by means of a tubular sleeve which is axially displaceable on a threaded spindle.

Nach einer weiteren Ausgestaltung der vorliegenden Erfindung wird die Verschwenkbarkeit der Widerlager erreicht, indem das obere Widerlager ein Rohr umfaßt, welches ein Gelenkrohr drehbar und unverlierbar umgreift, wobei das Gelenkrohr an der Rohrhülse befestigt ist.According to a further embodiment of the present invention, the pivotability of the abutment is achieved in that the upper abutment comprises a tube which rotatably and captively encompasses an articulated tube, the articulated tube being fastened to the tube sleeve.

Vorzugsweise sind an beiden Enden des Gelenkrohrs Bünde angebracht, die als Anschlag und als Führung des Rohrs dienen, welches Bestandteil des oberen Widerlagers ist.Frets are preferably attached to both ends of the articulated tube, which serve as a stop and as a guide for the tube which is part of the upper abutment.

Nach einer bevorzugten Ausgestaltung der vorliegenden Erfindung umfaßt das untere Widerlager einen Winkel auf seiner Oberseite, der das untere Widerlager quer zu dessen Längsrichtung überragt, um nach der Montage der Schutzgeländer-Zwinge Verkippungen der Gewindespindel und des unteren Widerlagers um dessen Achse zu verhindern.According to a preferred embodiment of the present invention, the lower abutment comprises an angle on its upper side, which projects beyond the lower abutment transversely to its longitudinal direction, in order to prevent tilting of the threaded spindle and the lower abutment about its axis after the assembly of the protective railing clamp.

Ein weiterer Vorteil der vorliegenden Erfindung erwächst aus der Verschwenkbarkeit des unteren Widerlagers gegenüber dem oberen Widerlager um die Achse der Gewindespindel, wodurch baulichen Gegebenheiten Rechnung getragen werden kann.Another advantage of the present invention arises from the pivotability of the lower abutment relative to the upper abutment about the axis of the threaded spindle, as a result of which structural conditions can be taken into account.

Nach einer weiteren Ausgestaltung der vorliegenden Erfindung kann für die Festlegung des oberen Widerlagers eine Gewindehülse auf die Gewindespindel aufgeschraubt werden, die zwei mit Bohrungen versehene Laschen aufweist, wobei die Bohrungen zur Aufnahme eines auf einer Baustelle verfügbaren Werkzeugs, wie zum Beispiel eines Zimmermannshammers, dienen können.According to a further embodiment of the present invention, a threaded sleeve can be screwed onto the threaded spindle for fixing the upper abutment, said threaded sleeve having two tabs provided with bores, the bores being able to accommodate a tool available on a construction site, such as a carpenter's hammer .

Wie aus Fig. 1 ersichtlich ist, umfaßt die Universalzwinge eine Gewindespindel 1 und ein stabförmiges Geländerteil 2. An dem unteren Ende der Gewindespindel 1 ist ein Vierkantrohr 3 derartig befestigt, daß das Vierkantrohr 3 in etwa senkrecht von der Gewindespindel 1 einseitig wegragt. Dabei liegt das untere Ende der Gewindespindel 1 auf der inneren Bodenfläche des Vierkantrohrs 3 auf. Auf der Oberseite des Vierkantrohrs 3 ist im Verbindungsbereich mit der Gewindespindel 1 ein Winkel 4 angebracht, der das Vierkantrohr 3, quer zu dessen Längsrichtung, überragt. Dieser Winkel 4 hat die Aufgabe, nach der Montage der Universalzwinge Verkippungen der Gewindespindel 1 und des Vierkantrohrs 3 um dessen Längsachse zu erschweren und dient als Widerlager (siehe dazu auch die Fig. 4 und Fig. 5).As can be seen from FIG. 1, the universal clamp comprises a threaded spindle 1 and a rod-shaped railing part 2. A square tube 3 is fastened to the lower end of the threaded spindle 1 in such a way that the square tube 3 projects away from the threaded spindle 1 approximately perpendicularly on one side. The lower end of the threaded spindle 1 rests on the inner bottom surface of the square tube 3. On the upper side of the square tube 3, in the connection area with the threaded spindle 1, there is an angle 4, which projects beyond the square tube 3 transversely to its longitudinal direction. This angle 4 has the task of making it difficult to tilt the threaded spindle 1 and the square tube 3 about its longitudinal axis after the universal clamp has been installed, and serves as an abutment (see also FIGS. 4 and 5).

Auf die Gewindespindel 1 wird eine Gewindehülse 5 aufgeschraubt, die zwei gegenüberliegende Laschen 6 aufweist (siehe Fig. 2), die jeweils mit einer Bohrung 7 versehen sind. Die Bohrungen 7 haben zum Beispiel einen zur Aufnahme eines Werkzeugs geeigneten Durchmesser wie zum Beispiel eines Zimmermannshammers.A threaded sleeve 5 is screwed onto the threaded spindle 1, which has two opposite tabs 6 (see FIG. 2), each of which is provided with a bore 7. The bores 7 have, for example, a diameter suitable for holding a tool, such as a carpenter's hammer.

Es wird weiterhin Bezug genommen auf Fig. 1. Eine T-förmige Rohrhülse 8 mit glatter Innenseite ist axial verschiebbar auf der Gewindespindel 1 angebracht und mit einem inneren Gelenkrohr 9 verbunden, das von einem zweiten Vierkantrohr 12 aufgenommen wird, das mit dem stabförmigen Geländerteil 2 verbunden ist. Das Gelenkrohr 9 ist als seitliche Verlängerung an der T-förmigen Rohrhülse 8 befestigt und weist an seinen beiden Enden jeweils einen fest angebrachten Bund 10, 11 auf, der als Anschlag und als Führung dient. Das Vierkantrohr 12 umschließt somit verdrehbar das Gelenkrohr 9 im Bereich zwischen den beiden Bünden 10, 11, wobei das Vierkantrohr 12 gegenüber dem Gelenkrohr 9 axial nicht verschiebbar ist. Auf der Oberseite des Vierkantrohrs 12 ist senkrecht nach oben wegragend das stabförmige Geländerteil 2 starr befestigt. An der Unterseite des Vierkantrohrs 12 ist eine U-förmige Auflage 13 zur Erhöhung der Stabilität angebracht (siehe Fig. 3). Zusätzlich dazu ist zur Aussteifung ein Keil 14 mit der Oberseite des Vierkantrohrs 12 und der der Gewindespindel 1 zugekehrten Seite des stabförmigen Geländerteils 2 verbunden.Reference is also made to FIG. 1. A T-shaped tubular sleeve 8 with a smooth inside is axially displaceably mounted on the threaded spindle 1 and connected to an inner joint tube 9 which is received by a second square tube 12 which is connected to the rod-shaped railing part 2 connected is. The articulated tube 9 is attached as a lateral extension to the T-shaped tube sleeve 8 and has a fixed collar 10, 11 at both ends, which serves as a stop and as a guide. The square tube 12 thus rotatably surrounds the articulated tube 9 in the area between the two collars 10, 11, the square tube 12 being axially non-displaceable relative to the articulated tube 9. On the top of the square tube 12, the rod-shaped railing part 2 protruding vertically upwards is rigidly attached. A U-shaped support 13 is attached to the underside of the square tube 12 to increase the stability (see FIG. 3). In addition, a wedge 14 is connected to the top of the square tube 12 and the side of the rod-shaped railing part 2 facing the threaded spindle 1 for stiffening.

An der von der Gewindespindel 1 abgewandten Seite des Geländerteils 2 sind zwei nach oben geöffnete, aus einem Stück geformte Geländerhalterungen 15 angebracht. Die Geländerhalterung 15 weist einen unteren Bereich auf, der fest mit dem Geländerteil 2 verbunden ist, und einen oberen Bereich, der von dem Geländerteil 2 beabstandet ist, um als Aufnahme von Geländerbrettern 21 zu dienen (siehe Fig. 4 und Fig. 5), wobei aufgrund des relativ großen Abstands des oberen Teils der Geländerhalterung 15 von dem Geländerteil 2 auch zwei Geländerbretter 21 hintereinander befestigt werden können. Zudem weist das Geländerteil 2 eine nach unten geöffnete, der Geländerhalterung 15 gleichende Geländerhalterung 16 auf, die an einer auf dem Geländerteil 2 verschiebbaren Laufhülse 17 befestigt ist. Die Geländerhalterungen 15, 16 sind jeweils mit einer Bohrung 18 versehen, die zur Aufnahme von Schrauben oder Nägeln dienen, mit denen die Geländerbretter 21 angeschraubt werden können.On the side of the railing part 2 facing away from the threaded spindle 1, two railing brackets 15 which are open at the top and are formed from one piece are attached. The railing bracket 15 has a lower region which is fixedly connected to the railing part 2 and an upper region which is spaced apart from the railing part 2 in order to serve as a receptacle for railing boards 21 (see FIGS. 4 and Fig. 5), wherein due to the relatively large distance of the upper part of the railing bracket 15 from the railing part 2, two railing boards 21 can be attached one behind the other. In addition, the railing part 2 has a railing holder 16 which is open at the bottom and is similar to the railing holder 15 and is fastened to a running sleeve 17 which can be displaced on the railing part 2. The railing brackets 15, 16 are each provided with a bore 18, which serve to receive screws or nails with which the railing boards 21 can be screwed on.

Wie aus Fig. 4 ersichtlich ist, wird zur Montage der Universalzwinge an einer Treppe 19 das obere Vierkantrohr 12 mit der U-förmigen Auflage 13 im Eckbereich auf eine Treppenstufe gelegt, so daß die Gewindespindel 1 außen parallel zur Treppe 19 verläuft. Durch Drehen des Gelenkrohrs 9 in dem Vierkantrohr 12 kann die Gewindespindel 1 in eine Winkelstellung zu dem Geländerteil 2 gebracht werden, die es erlaubt, das Vierkantrohr 3 mit dem darauf angebrachten Winkel 4 an die schräge Unterseite der Treppe 19 anzulegen. Die U-förmige Auflage 13 des Vierkantrohrs 12 dient also als oberes Widerlager der Zwinge und der Winkel 4 und das Vierkantrohr 3 dienen als unteres Widerlager der Zwinge bei deren Befestigung. Die Verkippung des Vierkantrohrs 3 gegenüber dem Vierkantrohr 12 wird aus der Fig. 3 deutlich, die einen Schnitt längs der Linie III-III in Fig. 1 zeigt. In dieser Abbildung sind zwei verkippte Positionen 3'' des Vierkantrohres 3 strichpunktiert angedeutet, wie sie zum Beispiel bei der Montage der Universalzwinge an einer Treppe 19 auftreten. Durch Andrehen der Gewindehülse 5 unter Zuhilfenahme eines Zimmermannshammers oder eines ähnlichen auf einer Baustelle verfügbaren Werkzeugs wird die Universalzwinge fest mit der Treppe 19 verbunden. In die Geländerhalterungen 15, 16 zweier oder mehrerer derart befestigter Universalzwingen können Geländerbretter 21 eingelegt werden, um die Treppe 19 vorschriftsmäßig zu sichern. Dabei können die Geländerbretter 21 sowohl, wie in Fig. 4 eingezeichnet, parallel zur Oberkante der Treppenstufen, als auch parallel zur schrägen Unterseite der Treppe 19 (nicht abgebildet) befestigt werden.As can be seen from FIG. 4, for mounting the universal clamp on a staircase 19, the upper square tube 12 with the U-shaped support 13 is placed in the corner area on a stair step, so that the threaded spindle 1 runs parallel to the outside of the staircase 19. By turning the articulated tube 9 in the square tube 12, the threaded spindle 1 can be brought into an angular position with respect to the railing part 2, which allows the square tube 3 with the angle 4 attached to it to be placed on the inclined underside of the stairs 19. The U-shaped support 13 of the square tube 12 thus serves as the upper abutment of the clamp and the angle 4 and the square tube 3 serve as the lower abutment of the clamp when fastening it. The tilting of the square tube 3 relative to the square tube 12 is clear from FIG. 3, which shows a section along the line III-III in FIG. 1. In this figure, two tilted positions 3 ″ of the square tube 3 are indicated by dash-dotted lines, as occur, for example, when mounting the universal clamp on a staircase 19. By tightening the threaded sleeve 5 with the aid of a carpenter's hammer or a similar tool available on a construction site, the universal clamp is firmly connected to the stairs 19. In the railing brackets 15, 16 two or more universal clamps fastened in this way can be inserted railing boards 21 to secure the stairs 19 in accordance with regulations. The railing boards 21 can be fastened both, as shown in FIG. 4, parallel to the upper edge of the stairs, and also parallel to the oblique underside of the stairs 19 (not shown).

Fig. 5 zeigt die Anbringung der Universalzwinge an einer ebenen Plattform 20. Im Gegensatz zur Anbringung an einer Treppe 19 wird hier die Gewindespindel 1 nicht gegen das Geländerteil 2 verkippt, so daß beide parallel zueinander stehen.Fig. 5 shows the attachment of the universal clamp on a flat platform 20. In contrast to attachment to a staircase 19, the threaded spindle 1 is not tilted against the railing part 2 so that both are parallel to each other.

Bauliche Gegebenheiten können es erforderlich machen, bei der Montage der Universalzwinge an einer Treppe 19 oder einer ebenen Plattform 20 die beiden Vierkantrohre 3, 12 gegeneinander waagerecht zu verschwenken. Diese Verschwenkung kann durch Drehen der Gewindespindel 1 in der Rohrhülse 8 vor dem Anziehen der Gewindehülse 5 ausgeführt werden. Die in Fig. 2 strichpunktiert ausgeführten Linien zeigen gegenüber dem Vierkantrohr 12 waagerecht verschwenkte Positionen 3' des Vierkantrohrs 3.Structural conditions may make it necessary to pivot the two square tubes 3, 12 horizontally against each other when installing the universal clamp on a staircase 19 or a flat platform 20. This pivoting can be carried out by turning the threaded spindle 1 in the tubular sleeve 8 before tightening the threaded sleeve 5. The lines shown in dash-dot lines in FIG. 2 show positions 3 ′ of the square tube 3 that are pivoted horizontally relative to the square tube 12.
