Embodiment Construction

[0019] figure 1 Housing 1 of the lock is shown with the lid open. For reasons of clarity, only the area of ​​the casing 1 where the coin 2 is checked is shown. A scanning element 3 is provided to verify the diameter of the coin 2 . An inserted coin 2 corresponding to a predetermined diameter can be further advanced in the direction of insertion, and then a key is opened by a mechanism not shown in the figure, also not shown here.

[0020] To explain how this works, reference will be made to the figure 2 The schematic cross-section shown and figure 1 . The scanning element 3 is substantially flat and has a peg 4 protruding downwards. This pin projects into an elongated hole 5 in the housing 1 .

[0021] For its part, the scanning element 3 has a groove 6 . The shape of this groove 6 corresponds to an elongated hole, while on one of its long sides there is another side groove 7 . A pin 8 protrudes from the housing 1 into this recess 6 . The scanning element 3 is presse...

Abstract

The invention relates to a deposit lock comprising a checking element which controls the diameter of an inserted deposit element with respect to the available value thereof and a key holding element, wherein said holding element releases the key when the value is available.

Description

technical field [0001] The invention relates to a deposit lock having a verification element for a deposit and a lock element for a key. Background technique [0002] Such a deposit lock is known, for example, from EP 1035523 A2. Such deposit locks are used, for example, for shopping trolleys which are connected to one another via a safety chain which is connected to a key in the parked state. To permit the use of such a shopping trolley, a deposit element, for example a deposit coin, must be inserted into the lock. [0003] These deposit coins vary in denomination and size. Typically, smaller coins have a lower denomination than larger coins. [0004] With a known lock, a deposit coin of predetermined denomination must be inserted to release the key. [0005] In the cited prior art, the maximum allowable coin diameter is verified by a slot that matches the pre-specified coin diameter and is sized to prevent the insertion of coins with a diameter larger than the specifie...
