Definitions

• the invention relates to a deposit lock and a method for testing a deposit with the features in the preamble of the method and Vorrich- main claim.
• Deposit locks in various embodiments are known from practice.
• the deposit locks together with a coupling element form a deposit system and serve to secure shopping carts or the like.
• Such deposit systems aim to ensure that the customer brings his shopping cart back to the collection point and the Carbox in commercial transactions. This should be achieved through a deposit, which must be inserted into the deposit lock to unlock the lock part and remove the car can. When returning the car, the deposit lock is locked again by inserting a coupling element and the deposit is issued.
• Such deposit locks should be tamper-proof and be able to check the pledge, usually a coin, as accurately as possible on its authenticity.
• the prior art systems are not sufficiently accurate in the deposit test and not tamper-proof.
• the invention solves this problem with the features in the method and device main claim.
• the claimed deposit test has the advantage of providing greater inspection accuracy and tamper resistance than the prior art.
• the accuracy of the test can be increased if there is a translation between deposit scanning and rotary tester, because even very small size differences lead to a clear reaction of the rotary tester.
• the rotary tester which ultimately decides on the release or blocking of the trigger of the lock part, is hidden inside the locker and can not be accessed and manipulated externally with tools. Also, the rotary tester can not be outsmarted by raising the deposit scan with a tool because the release of the rotary tester occurs in an intermediate scan position that can not be met in a tampering attempt.
• the deposit lock has the advantage that it can be adjusted in a simple and cost-effective manner to a variety of deposit sizes. For this purpose, only a few parts, especially the rotary tester, the receiving slot and the deposit plunger to adjust. The other components of the deposit lock can remain the same. Due to the identical parts, a very cost-effective production of the deposit lock is possible.
• the deposit lock allows on the one hand the aforementioned exact coin check. If only one specific deposit size is specified, extreme test accuracy can be achieved. On the other hand, the deposit lock offers the possibility of operating with several differently sized pawns or coins, whereby a high test accuracy can be achieved despite the deposit differences. As a result, the deposit lock has a very wide range of applications, whereby a wide variety of customer needs can be met with minimal effort.
• the operation with several different sized pledges or coins can be done in conjunction with a single receiving slot (deposit area) or several possibly parallel receiving slots (deposit selection).
• the range of allowable pledges or deposit sizes can be spread as far as desired in both variants and changed in a simple and cost-effective manner if necessary and adapted to different conditions of use, eg different coin sizes in different countries. Even retrofits or conversions are possible at the deposit lock in the various design and function variants (individual deposit, pledge area and deposit selection) in a simple and cost-effective manner.
• the deposit lock can also be equipped with a very effective deposit barrier, which prevents unauthorized deposit collection.
• a lever ratio and a translation can be effective and implement small actuating movements in large blocking movements.
• the hidden accommodation of the deposit check in the case of the deposit lock is also favorable.
• the deposit check area is only accessible from the outside through narrow slits, which can also be adapted to the deposit size and provide a rough preselection of the deposit size.
• the deposit lock also has the advantage that the deposit can be pushed very deep into the slot and from the outside is very difficult to reach. When unlocking the deposit lock, it is safely ejected again by the forced guides.
• the recoverable backlash of the movable pawn lock parts are given.
