A system, including an operating bar, for locking castor units mounted on movable bodies, for example, refuse bins

摘要

A system for locking lockable castor units mounted on movable bodies, for example, refuse bins, comprises at least one actuator mechanism (20) for a castor unit, the mechanism having a casing (33, 34) with a transverse hole (35) for the insertion of an operating bar (21) having at least one annular groove (32) near a conical end (21a) thereof. A wire spring (37) mounted on the casing (33, 34) deforms resiliently to enable the bar (21) to be inserted in the transverse hole (35) and snap-engages in the groove (32) to lock the movement of the bar (21), preventing it from coming out.
