Abstract
The invention concerns a coupling for the connection of scaffolding components having a coupling mouth in which the closing motion of the jaws is induced by a tensioning means configured as a wedge with ribs running diagonally against its direction of motion during tensioning. In the present invention the ribs (39, 49) work together with teeth (32, 44) on a moveable jaw (20) of the coupling mouth, and the wedge (30) has a curved cross section.
Claims7
A coupling for scaffolding components comprising:
- a housing having an opening;
- a jaw having teeth, the jaw mounted to the housing for rotation about a rotation axis;
- and
- a wedge member having an insertion axis and parallel ribs extending diagonally with respect to the insertion axis, the wedge member having a surface curved transversely to the insertion axis, the ribs being adapted to engage the teeth for rotating the jaw during insertion of the wedge member into the opening in a direction of the insertion axis.

A coupling for scaffolding components comprising:
- a housing having an opening;
- a jaw mounted to the housing for rotation about a rotation axis and having teeth protruding radially with respect to the rotation axis;
- and
- a wedge member having an insertion axis and parallel fibs extending diagonally with respect to the insertion axis, the wedge member having a surface curved transversely to the insertion axis, the ribs being adapted to engage the teeth for rotting the jaw during insertion of the wedge member into the opening in a direction of the insertion axis substantially parallel to the rotation axis.
