Abstract

1. A coupling between an upright (1) and a transverse element (2), particularly of a scaffold, in which the transverse element (2) is provided at its end with a pin (4) extending under an angle relative to the longitudinal axis of the transverse element (2), said pin engaging hookwise with an eye (3) provided at the side of the upright (1), the free end portion of the pin (4) projecting beyond the eye (3) having a substantially vertical slot (8), in which is provided a wedge-shaped pawl (9) which is pivotable around a pivot axis (10) between an inoperative position in which it does not hinder entering of removing respectively of the pin (4), and an operative blocking position in which it projects from the side of the slot (8), characterized in that the pin (4), the eye (3) and the pawl (9) have such relative dimensions that in the inoperative position of the pawl (9) a lever-shaped end thereof projects below the free end portion of the pin (4), while in the operative blocking position the end of the pawl (9) remote from the lever-shaped end cooperates as a cam surface with the adjacent lower edge (3') of the eye (3) and with progressive rotation of the lever-shaped end in the direction towards the upright (1) causes increased clamping of both parts.

Description

Die Erfindung bezieht sich auf eine Kupplung zwischen einem Ständer und einem Querelement, insbesondere eines Gerüstes, wobei das Querelement an seinem Ende mit einem sich in einem Winkel zur Längsachse des Querelements erstreckenden Stift versehen ist, der hakenartig in einer an der Seite am Ständer vorhandenen Oese eingreift, von welchem Stift der aus der Oese hinausragende freie Endabschnitt mit einem Schlitz zum Aufnehmen eines Sicherungskeils versehen ist.The invention relates to a coupling between a stand and a cross element, in particular a scaffold, the cross element being provided at its end with a pin which extends at an angle to the longitudinal axis of the cross element and which is hook-like in an eyelet provided on the side of the stand engages from which pin the free end portion protruding from the eyelet is provided with a slot for receiving a securing wedge.

Eine derartige Kupplung ist aus der französischen Patentschrift 1.093.342 bekannt. Bei dieser bekannten Kupplung erstreckt sich der im Stift vorhandene Schlitz sich in einer Ebene, welche quer zur Längsachse des Querelements gerichtet ist, während der Sicherungskeil als ein loses Teil ausgebildet ist, das nach dem in die Oese Hineinstecken des Stiftes in den Schlitz gebracht und angeschlagen wird. Die Ausbildung des Sicherungskeils als gesondertes Teil hat ja den Nachteil des leichten Verlorengehens. Ein weiterer Nachteil dieser Kupplung ist mit dem Umstand verbunden, dass der Sicherungskeil von der Seite her, also quer mit Bezug auf die Ebene durch die Längsachsen des Ständers und des Querelements angebracht werden muss. Der Sicherungskeil befindet sich also in wirksamer Lage in einer Position, in der er leicht zugänglich ist für zufällig oder unbefugt ausgeübte Kräfte, unter Einfluss deren der Sicherungskeil sich lockern würde.Such a coupling is known from French patent 1,093,342. In this known coupling, the slot present in the pin extends in a plane which is directed transversely to the longitudinal axis of the cross element, while the securing wedge is designed as a loose part which is brought into the slot and struck after being inserted into the eye of the pin becomes. The formation of the safety wedge as a separate part has the disadvantage of being easily lost. Another disadvantage of this coupling is connected with the fact that the securing wedge passes from the side, that is to say transversely with respect to the plane the longitudinal axes of the stand and the cross member must be attached. The securing wedge is thus in an effective position in a position in which it is easily accessible for forces which are exerted accidentally or unauthorized, under the influence of which the securing wedge would loosen.

Erfindungsgemäss werden diese Bedenken in einfachster Weise und zweckmässig dadurch behoben, dass der Schlitz sich in einer Richtung erstreckt, die in oder nahezu in der Ebene durch die Längsachse des Querelements fällt, während der Keil um eine Querachse kippbar in dem Schlitz angeordnet ist und drehbar ist zwischen einer unwirksamen Lage, in der er nur in achsialer Richtung aus dem Stiftende hinausragt, und einer wirksamen Lage, in der er an der Seite aus dem Schlitz hinausragt und mit seinem dem Querelement zugekehrten Längsende als Keilfläche mit der gegenüberliegenden Stirnrandfläche der Oese zusammenwirkt.According to the invention, these concerns are solved in a simple and expedient manner in that the slot extends in a direction that falls in or almost in the plane through the longitudinal axis of the cross element, while the wedge is arranged in the slot and can be rotated about a transverse axis between an ineffective position, in which it only protrudes axially from the end of the pin, and an effective position, in which it protrudes from the side of the slot and, with its longitudinal end facing the cross element, cooperates as a wedge surface with the opposite end edge surface of the eyelet.

Bei der erfindungsgemässen Kupplung kann der Sicherungskeil nach dem Hineinstecken des Stiftes in die Oese in einfacher Weise in die wirksame Sicherungslage gebracht werden, in dem der aus der Oese ausragende Endabschnitt des Keils in der Richtung zum Ständer angeschlagen wird, wodurch das gegenüberliegende Ende an der Seite aus dem Keil hinaus und in Eingriff mit dem betreffenden Stirnrandfläche der Oese tritt. Sowohl der in achsialer Richtung ausserhalb des Stiftendes ausragende, angeschlagene Endabschnitt des Keils, wie auch das wirksame Keilende desselben befinden sich dann in einerPosition, in der der Sicherungskeil besser gegen unbeabsichtigtes Lockern geschützt ist.In the coupling according to the invention, after the pin has been inserted into the eyelet, the securing wedge can be brought into the effective securing position in a simple manner, in that the end section of the wedge protruding from the eyelet is struck in the direction of the stand, as a result of which the opposite end on the side out of the wedge and into engagement with the relevant front edge surface of the eyelet. Both the struck end portion of the wedge protruding axially outside the pin end and the effective wedge end thereof are then in a position in which the securing wedge is better protected against unintentional loosening.

Die Erfindung wird unten an Hand der Zeichnung mit einem Ausführungsbeispiel näher erläutert. Es zeigen:

  • Fig. 1 eine Seitenansicht der erfindungsgemässen Kupplung, wobei die Oese und der in derselben greifende Stift in Achsialschnitt dargestellt sind;
  • Fig. 2 einen Schnitt nach der Linie 11-11 in Fig. 1 und
  • Fig. 3 einen Schnitt nach der Linie III-III in Fig. 1.
The invention is explained below with reference to the drawing with an embodiment. Show it:
  • F ig. 1 shows a side view of the coupling according to the invention, the eye and the pin engaging in the same being shown in axial section;
  • Fig. 2 shows a section along the line 11-11 in Fig. 1 and
  • 3 shows a section along the line III-III in FIG. 1st

In der Zeichnung ist mit 1 der vorzugsweise aus einem Metallrohr bestehende Ständer bezeichnet, während mit 2 ein mit ihm zu verbindendes, vorzugsweise ebenfalls aus einem Rohr des gleichen Typs bestehendes Querelement bezeichnet ist. Der Ständer 1 und das Querelement 2 bilden zum Beispiel Teile eines Baugerüstes.In the drawing, 1 denotes the stand, which preferably consists of a metal tube, while 2 denotes a cross element to be connected to it, preferably also consisting of a tube of the same type. The stand 1 and the cross member 2 form parts of a scaffolding, for example.

Zum Zustandebringen der Verbindung zwischen dem Ständer 1 und dem Querelement 2 ist der Ständer 1 mit einer an der Seite desselben ausragenden Oese 3 versehen, während das Querelement 2 am betreffenden Ende mit einem Stift 4 versehen ist, mit Hilfe dessen das Querelement hakenartig in die Oese 3 eingreifen kann.To bring about the connection between the stand 1 and the cross element 2, the stand 1 is provided with a protruding eyelet 3 on the side thereof, while the cross element 2 is provided at the relevant end with a pin 4, with the aid of which the cross element is hook-like in the eyelet 3 can intervene.

Im gezeichneten Ausführungsbeispiel bildet die Oese 3 einen Teil einer Gruppe von Vier von derartigen Oesen, die zusammen ein Formstück 5 bilden, dass in achsialer Richtung auf das Ständerrohr aufgeschoben werden kann und mit Hilfe von in der Zeichnung nicht näher dargestellten Mitteln, zum Beispiel Klemmschrauben, festgesetzt werden kann. Die Oesen 3 des Formstückes 5 können jede einen Stift eines mit dem Ständer 1 zu verbindenden Querelements aufnehmen.In the exemplary embodiment shown, the eyelet 3 forms part of a group of four such eyelets, which together form a shaped piece 5 that can be pushed onto the stand tube in the axial direction and with the aid of means not shown in the drawing, for example clamping screws, can be fixed. The eyelets 3 of the shaped piece 5 can each receive a pin of a cross element to be connected to the stand 1.

Der Stift 3 bildet einen Teil eines hakenförmigen Einsatz 6, der mit einem zylindrischen Abschnitt 7 in das betreffende Ende des Rohres des Querelements 2 gesteckt werden kann und in diesem durch geeignete Klemmittel fixiert werden kann.The pin 3 forms part of a hook-shaped insert 6, which can be inserted with a cylindrical section 7 into the relevant end of the tube of the cross element 2 and can be fixed in this by suitable clamping means.

Der Stift weist einen Schlitz 8 auf, der von einem achsialen Einschnitt gebildet wird, welcher Einschnitt in einer Ebene durch die Achse des zu verbindenden Querelements 2 liegt. In diesem Schlitz ist ein Sicherungskeil 9 um einen Gelenkbolzen 10 drehbar montiert. Dieser Sicherungskeil ragt an seinem von der Oese 3 abgekehrten spitz zulaufenden Ende in achsialer » Richtung ausserhalb des Stiftes 4 aus und fällt in seiner unwirksamen, in der Zeichnung mit Strichlinien angegebenen Lage mit seinen Längskanten ganz innerhalb der Seitenbegrenzungen des Stiftes 4.The pin has a slot 8 which is formed by an axial incision, which incision lies in a plane through the axis of the cross element 2 to be connected. In this slot, a locking wedge 9 is rotatably mounted about a hinge pin 10. This safety wedge protrudes at its pointed end facing away from the eyelet 3 in the axial »direction outside the pin 4 and falls in its ineffective position, indicated by dashed lines in the drawing, with its longitudinal edges entirely within the side boundaries of the pin 4.

An der dem Ständer 1 zugekehrten Seite ist ein Anschlag im Schlitz 8 gebildet, der die Schwenkfreiheit des Sicherungskeils 9 in der Weise begrenzt, dass beim in die Oese 3 Stecken des Stiftes 4 der Sicherungskeil 9 keine das Hineinstecken hindernde Position einnehmen kann, aber dabei während des Hineinsteckens automatisch in seine unwirksame (in der Zeichnung mit Strichlinien angegebene) Lage gedrückt wird. Dieser Anschlag wird im gezeichneten Ausführungsbeispiel von zwei Querstiften 11 gebildet. Nach dem Hineinstecken des Stiftes 4 in die Oese 3 wird der Sicherungskeil 9 aus seiner mit Strichlinien angegebenen unwirksamen Lage durch Ausüben einer Kraft in der Richtung des Pfeiles P in seine wirksame, mit vollen Linien angegebene Lage gebracht. Dabei wirkt das breite Ende des Sicherungskeils 9, das einen allmählich zunehmenden Radius in Bezug auf die Drehungsachse 10 aufweist, wie eine Keilfläche mit der unteren Endkante 31 der Oese 3 zusammen und wird der Stift 4 abwärts in die Oese 3 festgezogen.On the side facing the stand 1, a stop is formed in the slot 8, which limits the freedom of pivoting of the securing wedge 9 in such a way that when the pin 4 is inserted into the eyelet 3, the securing wedge 9 cannot assume an obstructing position, but during this inserting it automatically into its ineffective position (indicated by dashed lines in the drawing). This stop is formed by two cross pins 11 in the illustrated embodiment. After inserting the pin 4 into the eyelet 3, the securing wedge 9 is brought out of its ineffective position indicated by broken lines by exerting a force in the direction of the arrow P into its effective position indicated by solid lines. The broad end of the securing wedge 9, which has a gradually increasing radius with respect to the axis of rotation 10, acts like a wedge surface with the lower end edge 3 1 of the eyelet 3 and the pin 4 is tightened downwards into the eyelet 3.

Das Lösen des Sicherungskeils und damit der Kupplung zwischen dem Querelements 2 und dem Ständer 1 kann bewirkt werden, indem eine Kraft in der · Richtung des Pfeiles Q ausgeübt wird.The release of the securing wedge and thus the coupling between the cross element 2 and the stand 1 can be brought about by exerting a force in the direction of the arrow Q.
