Abstract (en)
Coupling system for detachably coupling a substantially rectangular construction member to and between two uprights (2) in particular a railing (4) to a scaffold (1), by means of claw parts (7) mounted at the corners of the member (4) and projections (15, 16) mounted on the uprights (2) to interact with the claw parts (7). In the coupled state the member (4) is in a vertical position in a plane through the uprights (2). For the purpose of uncoupling, the member (4) must be displaced upwards and then rotated about an axis through the upper projections so that the lower claw parts (7) are released from the corresponding lower projections (16), to a certain minimum inclined position of the member (4) or further so that the upper claw parts (7) can then be released from the corresponding projections (15) by obliquely displacing the member (4) upwards. For the purpose of coupling the steps for uncoupling must be carried out in the reverse order.
