Abstract: A coin-deposit lock to be placed on a trolley being part of a row of mutually connected e.g. shopping trolleys or baggage trolleys comprises a main slide being longitudinally slidable against the force from a spring and a measuring slide likewise longitudinally slidable against the force from a second spring. Each of the slides has a transverse central aperture, and when a coin of a certain value (diameter) has been inserted between the slides, the apertures are mutually aligned. Upon insertion of a key belonging to the lock in a first key opening in the lock, the slides can be moved to a position in which a latching finger on a pivotable release member engages in the mutually aligned apertures and retains the slides and the coin between them in a withdrawn position. At the same time, the release member pivots to a position, in which a second latching finger on it frees a second key associated with a previous trolley in the row thus freeing the trolley from the row.

Abstract: Deposit locks for transport carts are in use in which the coupling member of one cart is lockable in the deposit lock of the next cart, and the deposit lock has a locking mechanism which upon insertion of a deposit token into the locking mechanism locks the token while releasing the cart and releases the token upon recoupling of the cart.

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.

Abstract: In a device for confining shopping carts, which is in the form of an accessory unit with control and locking devices (30, 40, 50) for known coin deposit systems (20) for one, an external permanent magnet as a control element (30) is disposed at the end of a shopping cart row which, when passing through the magnetic field (M), interacts with the locking elements (40, 50) of the coin deposit system (20) in such a way that it becomes possible to set up the operational states "Release" (ready to operate) or "Lock" (not ready to operate) exclusively. Therefore, with the appropriate disposition and size of these components there is operational readiness exclusively in the area of the shopping cart row. This contact-free interaction is easy to realize structurally and can be securely protected from third party intervention (FIG. 2).

Abstract: A coin slide (11) bearing a coin is movable into a casing (2) of a coin lock (1) to release a locking member (14) and allow full insertion of the coin slide (11). In this position a space (recess 20) in the coin slide (11) is aligned with a space (aperture 21) in a coupling member (8) and with a space (aperture (19) in a casing position separating the coin slide (11) and the coupling member (8). A locking member (e.g. ball 18) in the apertures (19 and 21) may now be moved upwardly, on pulling of the coupling member (8), to occupy the recess (20) and the aperture (19) so as to allow complete withdrawal of the coupling member (8), e.g. to free a shopping trolley. The coin is released by reversing the procedure on re-insertion of the coupling member (8).

Abstract: A system for retrieving shopping carts at a store having a plurality of shopping carts is disclosed. The system includes a counter which can be preset to a first determined count. A target is mounted to each shopping cart while a sensor detects the return of each shopping cart to a designated area. As each shopping cart is returned to the designated area, the sensor generates an output pulse which changes the count in the counter. Whenever the count in the counter achieves a second predetermined count, an alarm is activated indicative that a prize is awarded to the person returning the shopping cart to the designated area.

Abstract: A shopping cart rental system containing one or more stations (49) per shopping center, several locking mechanisms (43) per station, and one shopping cart per locking mechanism. A bail (23) permanently fastened to a shopping cart locks into the locking mechanism. Three quarters inserted into the three coin slots (28) and simultaneously depressed by the flap (34) mechanically unlock the bail, releasing the cart. When the cart is returned and the bail is reinserted into the locking mechanism, the locking mechanism once again secures the bail in place and at the same time returns, by mechanical actuation only, one of the three quarters that was initially used to release the cart.

Abstract: The device comprises a housing attachable to the handle bar of a nestable cart, such as a shopping cart. The housing has a front and a back key slot, each for receiving a key. Key locking members are mounted in the housing, each associated with a key slot. These locking members are interconnected by a position-inverting mechanism, so that when one locking member is in a key-locking and retaining position, the other locking member is in a key-releasing position, and vice versa. A key is attached to each housing by means of a flexible link, such as a chain, long enough to be inserted into the back key slot of the housing of the next nested cart. However the flexible link can be longer than this requirement. The keys are retained in their back key slots and thus the carts are interlocked in a nested position. The key of the frontmost cart is used to unlock the latter.

Abstract: A security device (10) to releasably secure articles in a queue, row or stack has a body (11, 12) to be clamped on one of the articles by a loop section (14) and lugs (17). A key (26) attached by a chain or cable to a second device (10) is received in a slot (30, 31) in the body and is releasably engaged by a peg (39) on a pivotally mounted operating arm (34), in a cavity (29) of the body entering a slot (27) in the key (26). The key (26) can only be released when a coin or token is received in a coin holder (47) in a pusher unit (48) which advances a tongue (40), the nose (41) of which engages a cam face (42) on the operating arm (34) to move the latter to release the key (26). The pusher unit (48) can only be moved to recover the coin or token from the coin holder (47) when the key (26) has been reinserted in the body and engaged by the operating arm (34).
