The present invention is directed to a device for locking and releasing objects intended for public use, such as luggage carts which can be taken from a common storage space and returned to the same. The device comprises a locking apparatus allowing each object to be automatically locked to an adjacent object or to a fixed point in compact storage position. A coin or the like is introduced into the locking apparatus to allow unlocking of the same and the concomitant release of the object by exerting a pull thereon. The locking apparatus returns the coin when the object is returned to the storage space and is locked to an adjacent object or to the fixed point. Unlocking of the object is accomplished by just exerting a pull thereon after the coin has been appropriately inserted into the locking apparatus.

A device for locking and releasing objects intended for public use, especially objects intended to be put at public disposal free of charge such as luggage carts in a railway station or an airport or shopping carts in self-service stores, such objects capable of being taken directly from a common storage station and returned to the storage station, said device including a locking apparatus in the form of a casing and adapted to be affixed to a part of each object, attaching means for affixing said locking apparatus to a part of each object, a connecting lock having male and female means secured to respective longitudinal endmost portions of said casing forming said locking apparatus, for locking each object to an adjacent object or to a fixed point in compact storage position, and a slit provided in said casing through which a coin or the like is introduced to allow unlocking of said locking apparatus and release of the object by exerting a pull thereon, said locking apparatus being arranged to return the coin or the like when the object is returned to the storage station and is locked by said connecting lock to the adjacent object or to the fixed point, wherein said female means is constituted by a clamp comprising two unsymmetrical jaws, and said male means is constituted by a connecting bar secured to the object or to the fixed point, and having a diameter perfectly calibrated so that said male means can fit in between said jaws, and wherein said locking apparatus comprises a slide provided with a tongue blocking said clamp in locked position so as to lock said connecting lock connecting the object to the adjacent object or to the fixed point, an internal blocking member for fixing said slide and being movable to a non-blocking position by coming into contact with an edge of the coin introduced within said slit, said slide being movable within said casing, after introducing the coin within the slit, under the single action of the pull on the object which is directly applied to the slide so as to successively move the blocking member to the non-blocking position by coming into contact with the edge of the inserted coin, unlock the clamp of the connecting lock connecting the object to the adjacent object or to the fixed point and release the object.
