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
wO 2006/097055 PCT/DE2005/000474 Deposit lock The invention relates to a deposit lock, which has a checking element for a deposit, and a locking element for a key.
A deposit lock such as this is known, for example, from EP 1035523 A2. Deposit locks such as these are used, for example, for shopping trolleys, which are connected to one another via a security chain, which is attached to the key, when in the parked state. In order to allow a shopping trolley such as this to be used, a deposit element, for example a deposit coin, must be inserted into the lock.
The deposit coins differ in their value and in their size. Normally, relatively small coins have a lower value than relatively large coins.
In the case of known locks, it is necessary to insert a deposit coin of the predetermined value in order to release the key.
In the cited prior art, the maximum permissible coin diameter is checked by means of an insertion slot which is matched to the predetermined coin diameter and whose dimensions prevent coins whose diameter is larger than the maximum permissible specified diameter from being inserted. In addition to this maximum value check, the diameter of the deposit coin is investigated within the deposit lock to determine whether the diameter is less than a predetermined minimum value.
Within the lock, the minimum value for the diameter of the coin is in this case checked as follows: one side of the edge of the coin rests on a stationary guide, and the opposite side of the coin edge is recorded by a scanning element. If the coin is of the predetermined
A deposit lock such as this is known, for example, from EP 1035523 A2. Deposit locks such as these are used, for example, for shopping trolleys, which are connected to one another via a security chain, which is attached to the key, when in the parked state. In order to allow a shopping trolley such as this to be used, a deposit element, for example a deposit coin, must be inserted into the lock.
The deposit coins differ in their value and in their size. Normally, relatively small coins have a lower value than relatively large coins.
In the case of known locks, it is necessary to insert a deposit coin of the predetermined value in order to release the key.
In the cited prior art, the maximum permissible coin diameter is checked by means of an insertion slot which is matched to the predetermined coin diameter and whose dimensions prevent coins whose diameter is larger than the maximum permissible specified diameter from being inserted. In addition to this maximum value check, the diameter of the deposit coin is investigated within the deposit lock to determine whether the diameter is less than a predetermined minimum value.
Within the lock, the minimum value for the diameter of the coin is in this case checked as follows: one side of the edge of the coin rests on a stationary guide, and the opposite side of the coin edge is recorded by a scanning element. If the coin is of the predetermined
- 2 -minimum diameter, the scanning element releases the release mechanism for the key.
It has now been found that known locks can also be released by smaller, and therefore less valuable, coins by manipulation. The smaller coins are first of all partially inserted into the insertion slot of the deposit lock, and a larger and therefore correct diameter is then simulated by moving the inserted coin laterally with respect to the insertion direction. This then overcomes the deposit lock.
In order to make such manipulation more difficult, deposit locks are known, such as those from DE 199 17 391 Al, which use two scanning elements that act independently of one another to check the diameter within the deposit lock. These scanning elements record the coin edge from different sides and then each autonomously check it for the predetermined minimum diameter. A smaller coin can simulate a correct coin by being moved laterally within the housing only at one of the two scanning elements, thus making it possible to prevent the lock from being released. However, this solution has the disadvantage that the number of parts is increased because there are twice as many scanning elements.
The object of the invention is therefore to provide a deposit lock in which it is harder to release the lock with a different coin than the intended coin, while furthermore keeping the number of parts used small.
This object is achieved by the subject matter of the main claim, and the dependent claims relate to advantageous refinements and/or further developments of the invention.

This object is achieved by the subject matter of the main claim, and the dependent claims relate to advantageous refinements and/or further developments of the invention.
- 3 -The considerations which have led to the creation of the present invention are based on the idea that increased security against manipulation is provided if the security chain can be released only when the single scanning element within the lock checks the diameter of the inserted coin to determine whether the diameter is less than or greater than the predetermined value. The security chain is then released only when it is found that this diameter has been neither undershot nor overshot. This narrowly limited range can be simulated only with difficulty by lateral movement of the coin in the deposit lock. At the same time, one scanning element is sufficient to determine whether the diameter is within the value range, thus advantageously keeping the number of parts required low.
Since all the checks are carried out within the lock, the insertion slot need no longer carry out the function of checking the maximum diameter. It is advantageously possible to use a standard insertion slot, and there is no need for the different insertion slots, each matched to one specific coin diameter. This advantageously simplifies the parts administration. The locks for different coins now differ only in the configuration of the single scanning element in the interior of the lock.
One possible exemplary embodiment of the invention will be explained in more detail in the following text with reference to the drawings, in which:
Figure 1 shows the view from above, in the form of a section illustration, of the interior of the lock with a coin, Figure 2 shows the lock as shown in Figure 1, in a side view sectioned along the line II-II, Figure 3 shows the view from Figure 1 with the scanning element initiated,

Figure 1 shows the view from above, in the form of a section illustration, of the interior of the lock with a coin, Figure 2 shows the lock as shown in Figure 1, in a side view sectioned along the line II-II, Figure 3 shows the view from Figure 1 with the scanning element initiated,
- 4 -Figure 4 shows the situation shown in Figure 1, with a coin that is too large, and Figure 5 shows the situation shown in Figure 1, with a coin that is too small.
Figure 1 shows the housing 1 of the lock with the cover open. For clarity reasons, only that area of the housing 1 in which the coin 2 is checked is shown. A
scanning element 3 is provided in order to check the diameter of the coin 2. An inserted coin 2 which corresponds to the predetermined diameter can then be pushed in further in the insertion direction then release a key, which is likewise not shown, via a mechanism that is not shown.
In order to explain the method of operation, reference will be made to the section illustration shown in Figure 2, as well as to Figure 1. The scanning element 3 is essentially flat and has a bolt 4 which projects downwards. This bolt projects into an elongated hole 5, which is located in the housing 1.
For its part, the scanning element 3 has a recess 6.
The shape of this recess 6 corresponds to an elongated hole with an additional side recess 7 on one of the longitudinal sides. A bolt 8 projects from the housing 1 into this recess 6. The scanning element 3 is pressed by a spring 9 against one side of the outer edge of the coin 2, while the other, opposite side of the outer edge of the coin rests on a side guide 10. The longitudinal axis through the elongated hole 5 runs parallel to the longitudinal axis of the areas 6a and 6b, which are like elongated holes, of the recess 6.
The freedom of movement of the scanning element 3 with respect to the housing 1 in the x-y direction is defined by the shape of the elongated hole 5 and the areas of the recess 6 which are like elongated holes and in which the bolts 4 and 8 are located.

The scanning element 3 is essentially flat and has a bolt 4 which projects downwards. This bolt projects into an elongated hole 5, which is located in the housing 1.
For its part, the scanning element 3 has a recess 6.
The shape of this recess 6 corresponds to an elongated hole with an additional side recess 7 on one of the longitudinal sides. A bolt 8 projects from the housing 1 into this recess 6. The scanning element 3 is pressed by a spring 9 against one side of the outer edge of the coin 2, while the other, opposite side of the outer edge of the coin rests on a side guide 10. The longitudinal axis through the elongated hole 5 runs parallel to the longitudinal axis of the areas 6a and 6b, which are like elongated holes, of the recess 6.
The freedom of movement of the scanning element 3 with respect to the housing 1 in the x-y direction is defined by the shape of the elongated hole 5 and the areas of the recess 6 which are like elongated holes and in which the bolts 4 and 8 are located.
5 PCT/DE2005/000474 The freedom of movement is provided mainly only in the x-direction since, in most positions which the scanning element 3 can assume, the two. If a coin with the correct diameter is located in the lock, as shown in Figures 1, 2 and 3, then the bolt 8 is located precisely opposite the side recess 7. If the coin is now pushed further into the lock, then the scanning element can also move with a y-component, by the bolt 8 entering the side recess 7, and the scanning element 3 pivoting around the bolt 4. This pivoting movement initiates the downstream mechanism to release the key.
Figure 4 now shows the situation with a coin 2a that is too small. The bolt 8 is located in the area 6a, which is like an elongated hole, of the recess 6. No pivoting movement is possible.
The same situation occurs when a coin 2b that is too large is inserted. In this situation, the bolt 8 is located in the area 6b, which is like an elongated hole, of the recess 6, and, once again no pivoting movement of the scanning element 3 is possible in this case.
As explained by the figures and the associated description, the present invention advantageously means that a pivoting movement is possible only when the scanning element 3 is located precisely in the position in which the bolt 8 is precisely opposite the side recess 7. The smaller the difference between the width of the recess 7 and the thickness of the bolt, the less is the tolerance for the coin diameter.
In the event of a manipulation attempt, in which an attempt is made to overcome the lock using a smaller coin, the person carrying out the manipulation will face the difficulty of first of all having to move the

The smaller the difference between the width of the recess 7 and the thickness of the bolt, the less is the tolerance for the coin diameter.
In the event of a manipulation attempt, in which an attempt is made to overcome the lock using a smaller coin, the person carrying out the manipulation will face the difficulty of first of all having to move the
- 6 -scanning element 3 to the exact position in the x-direction using a small coin 2a, and then of pushing this coin further into the lock in the y-direction without, however in the meantime changing the x-position of the scanning element.
In addition, the person carrying out the manipulation will be impeded in his attempt to carry out such misuse by the force of the spring 9, because this always presses the scanning element 3 into a position in which it is not possible to release the lock.
In a further refinement of the invention, which is not illustrated as a figure, it is possible to define two or more discrete values for a valid coin diameter.
For this purpose, further side recesses similar to the recess 7 must be provided. For example, the further side recess can be provided for the elongated hole 5.
The lock is now also released when the bolt 4 is opposite the additional recess.
The lock can then be released using different coins, thus improving the user convenience without there being a certain range of valid diameters. A range such as this would make it easier for a person carrying out manipulation to overcome the lock using a smaller coin.
According to the invention, there is actually no such range, thus advantageously making manipulation more difficult.
The described deposit lock according to the invention can be used wherever an object is made available to a user for a certain time and the value of the deposit coin is intended to motivate the user to return the object loaned to him to a predetermined return location again.
