Definitions

  • 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.
  • 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.
  • 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.
  • 1 denotes the stand, which preferably consists of a metal tube
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
