摘要

A coupling device (1) for coupling a load carrier to a towing hook (2) of a vehicle, which device comprises, a first coupling element (4) adapted to abut against a first portion of the towing hook (2) and a second coupling element adapted to abut a second portion of the towing hook (2). A frame (10) is arranged to accommodate at least the first portion of the towing hook (2) and a transfer linkage (12) for effecting displacement of the first coupling element (4) with respect to the frame (10). The first coupling element (4) is movably connected to the frame (10) and is associated with an end of the transfer linkage (12). The transfer linkage (12) comprises a first two-bar linkage (22) and a second two-bar linkage. The first and second two-bar linkages (22) are arranged in relation to each other such that when a force is applied to the second two-bar linkage the force is transferred via the first two-bar linkage (22) to the first coupling element (4) via the said end of the transfer linkage (12) for releasing or engaging the towing hook (2). Link bars of the two-bar linkages are in a defined angular relationship when the towing hook is engaged. A load carrier and use of a load carrier are also presented.
