DESCRIPTION:
BRIEF SUMMARY
The invention concerns a coin operated lock for delivering a locking means secured in said lock after the introduction of a means of payment, for example a coin, into said lock, as said lock comprises a chamber for receiving the locking means, members for securing the locking means in the chamber, a chamber for receiving a means of payment, and members for delivering the locking means after the introduction of the means of payment.
Locks of this kind are e.g. used in connection with shopping or similar carriages which can be borrowed by releasing them from an anchoring system provided by means of the locking means, after having put a means of payment into the lock, and where the introduced means of payment is payed back when again returning an re-anchoring the carriage.
It is the object of the invention to provide a lock of the kind disclosed adapted to decide by itself, whether the means of payment inserted has the right size, and thus the correct value.
According to the invention, this is obtained by the fact that a scanning member belonging to the chamber for the means of payment is adapted to scan, during a displacement movement the size of an inserted means of payment in the direction of the displacement movement of the scanning member, and corresponding to one or more of such sizes is provided with one or more recesses or passages for receiving a releasing member attached to the chamber for the locking means and adapted to get into an engagement connection with the recesses or passages in the scanning member in such a manner to cause the releasing of the locking means in order to remove it from the chamber of the locking means.
Thus, the control of the right size of the means of payment and thus of its correct value is carried out as the initial step of an operating manipulation which, after all, is necessary in order to release the locking means. This means that the control does not take extra time. Moreover, the structure according to the invention makes it possible to easily adapt the control mechanism to different sizes of means of payment and that the entire structure of the lock can be made space saving and robust.
According to the invention, the scanning member can consist of a measuring member and a movement member which are coupled together to the movement both at the same time and in relation to each other, the measuring member being provided with the recess or the passage or the recesses or passages, and the movement member having a passage for the releasing member for an engagement connection with the passage and a recess or passage when they occupy a displacement position aligned to each other. This embodiment allows a specific space saving structure, as the measuring member and the movement member can be formed as guides and slides positioned side by side.
According to the invention, the releasing member can be shaped as a pivotable member having a projection protruding to the one side of the pivot level for engagement with the passage and the recess or passage and a projection protruding to the opposite side in order to secure a locking means by means of which it may, during the rotation of the member, protrude into the chamber of the locking means. Also this structure can be formed simply, space-saving and robust.
According to the invention, the releasing member can be actuated by a spring which is active in the movement level of the locking means and which at the same time is protruding into the movement level of the movement member. When the spring is actuated by the movement member, the spring force can be used to clamp the releasing member and the parts of the scanning member in the releasing position. Moreover, this arrangement also means that the actuating does not take place before the movement member has approached or arrived at its active outmost position. Thus, it is avoided that the movable parts are getting into unnecessary wear-affording displacement-touch with each other.
According to the invention, an auxiliary member is attached to the releasing member for disconnectin
