DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a deposit lock for coupling together shopping or baggage carts, or the like, having a housing which can be attached to the shopping cart, which on one side has an insertion opening for a coupling member and on the other side an insertion opening for a coin and/or a card, and which has in an interior a holding device for fixing the coupling member in place and a receiving device for secure locking of the inserted coin or card, as well as a release mechanism, which releases the coupling member when the coin or card is inserted, and releases the coin or the card, when the coupling member is pushed in the receiving device.
2. Description of Prior Art
A deposit lock of this type is taught by European Patent Reference EP 0 572 879 A2. In this known deposit lock a control element is moved during insertion of the card or coin, which moves a locking bolt from a blocking into an unblocked position. The locking bolt is rotatable and is connected via a crank gear with the control element in the form of a slide or a carriage.
According to this invention, it is one object to make available a deposit lock of the type mentioned above, having a different design, which assures the dependable securing of the coupling member, or respectively of the inserted coin or card.
This object is attained with the steps recited in the specification and in the claims. In accordance with this invention, the releasing mechanism has a rocker with a pivot shaft, which is oriented transversely with respect to the insertion direction of the coupling member, or respectively the coin or card, and parallel with respect to a plane of the coin or card. By introducing the coin or card the rocker can be pivoted in the one direction, wherein the holding device releases the coupling member, and can be pivoted in the other direction by inserting the coupling member, wherein the receiving device releases the coin, or respectively card.
A dependable operation of the locking mechanisms with a central element in the form of the rocker is achieved with a release mechanism designed in this way. At the same time it is possible to operate further control elements for refining the functional process and of the locking mechanisms.
If the holding device is designed as a catch hook arranged on the rocker on the side of the pivot shaft facing the coupling member which, with no coin or card inserted, engages an arresting section of the coupling member from above or below or from the side, wherein the rocker is maintained in the assigned pivot position by a spring force, the holding device for the coupling element is simply designed, wherein a dependable function is assured.
In the uncoupled state, in the position securely enclosing the coin or the card, the rocker is dependably maintained because while inserting the coin or the card a bolt is moved in the insertion direction, which itself has an arresting piece, or which operates one, which in the inserted state of the coin or the card comes into operative contact with a counter-piece of the rocker and supports the rocker against the pivot direction caused by the spring force in such a way that the coupling member is released. Only a simply designed and operable bolt is needed for this purpose. In this connection, advantageously, the slide supports the rocker on a side of the rocker facing the insertion opening of the coin, or respectively card, with respect to the pivot shaft, and the slide has a section projecting to the other side, facing the coupling member with respect to the pivot shaft, whose front area comes into connection with the coupling member. Thus the rocker is securely maintained in the uncoupling position. For re-coupling, it is only necessary to slightly push the bolt with the coupling member back, whereafter the holding device of the coupling member snaps closed and the coupling member is securely held.
The coupling member is dependably released when the coin or card is inserted, and is dependably fixed in position whe
