Abstract

A structure of hook (100) comprises a hook (110) arranged to pass between a block configuration, where the hook (110) cannot rotate, and a unlock configuration, where the hook (110) can rotate about a first axis (x). The structure (100) comprises also a cam (120) arranged to rotate about a second axis (y), parallel to the first axis (x), to pass between a first position and a second position, said cam (120) being equipped with a arc shaped surface (121). The structure (100) also comprises an connection element (130) between the hook (110) and the cam (120), said connection element (130) being constrained to rotate about a third axis (z), parallel to the first and the second axis (x,y), and comprising a pure rolling constraint (131) configured in such a way to roll on the arc shaped surface (121), without sliding friction, when the cam (120) passes between the first position and the second position. The connection element (130) is also configured to allow a hook (110) to pass from the block configuration to the unlock configuration, when the cam (120) rotates about the second axis (y), passing from the first position to the second position, and the pure rolling constraint (131) rolls on the arc shaped surface (121).
