Abstract
A closure device for a withdrawable rack adapted for receiving power circuit breaker includes a plate arrangement having at least two plates provided with openings and movable relative to one another so that the plate arrangement is changeable between an open position in which the openings of the plates are in alignment and a closed position in which the openings are out of alignment. An actuating mechanism is acted upon by the power circuit breaker as it is inserted to cause a movement of at least one of the plates to thereby change the plate arrangement between the closed and open positions. The actuating mechanism includes two V-shaped linkage assemblies. Each linkage assembly has two legs connected by a hinge to allow the linkage assembly to spread apart, with one of the legs having a free end which is connected to the at least one of the plates, and a coupler is connected to the hinge. Both couplers are jointly articulated to actuating element.
