Definitions

  • the present invention relates to a coupling device for joining vertical and horizontal structural parts for building scaffolding, covering structures, tents, storage rooms, etc.
  • the coupling device comprises at least a cage arrangement located on the vertical structural part for receiving a hook means located on the horizontal structural part, and a wedge body for being inserted into the coupling device,
  • a problem associated with the prior art solutions is that the wedge element is a separate part which is not fixed to the coupling device or easily accessible during assembly of the coupling device.
  • An object of the present invention is to provide a coupling device that is reliable and stable and provides a rigid coupling connection.
  • Another object is that an operator shall be able to assemble the coupling in a simple and quick manner.
  • a third object is that the coupling device shall not be comprised of detached structural parts. Each structural element needed shall be bound to the structural parts to be assembled so that the operator does not have to spend time locating unattached elements during assembly.
  • a fourth object is that it shall be possible to disassemble the coupling in a simple and quick manner. This applies in particular to the removal of the wedge element, which may often present a great challenge to the operator.

Said length dimension decreases in a region below the top surface of the wedge body, which is also the impact surface 36 of the wedge body.

Abstract

L'invention porte sur un dispositif d'accouplement (1) pour réunir des parties structurelles verticales et horizontales (10, 20) pour échafaudage de construction, structures de couverture, tentes, chambres de stockage, etc. Le dispositif d'accouplement (1) comprend au moins un ensemble cage (13) situé sur la partie structurelle verticale (10) pour recevoir des moyens formant crochet (27) situés sur la partie structurelle horizontale (20), et un corps de coin (30, 31) destiné à être inséré dans le dispositif d'accouplement (1). La partie structurelle horizontale (20) comporte dans sa zone de jonction, au moins un trou traversant (21, 24, 25) pour recevoir le corps de coin (30, 31). Le corps de coin (30, 31) est formé avec une section principale supérieure (35) et au moins une section de patte inférieure (40), comprenant, respectivement, une première patte en forme de coin (43) destinée à être insérée entre les moyens formant crochet (27) et l'ensemble cage (13) et une deuxième patte d'impact (50) qui, après que le corps de coin (30, 31) a été inséré, fait saillie à partir d'une zone inférieure de l'accouplement (1) et est accessible dans celle-ci.
