ABSTRACT:
A coin lock for carts in which the body of the lock is provided with two levers which turn upon introduction of a coin and displace lock plates which release a closure locking plate by which the lock is held to an adjacent element. The levers are held in a closure locking plate release position by means of bars which swing in a vertical plane around individual pins and then engage and hold the levers apart and hold the levers and the lock plates in their releasing positions. Upon its introduction the closure locking plate acts against the elastic action of individual springs and presses against and turns the bars downward. This releases the levers and turns them, under the elastic action of individual springs, into the releasing position. This in turn frees the coin for removal.
