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).
