Description

-Z-

The invention relates to a device which is designed as a coin deposit coupling mechanism: and which, in accordance with the technology implemented here, which limits the required functional parts to a minimum, enables a compact, space-saving design.

Devices according to the invention are preferably used as so-called coin deposit return systems for shopping trolleys in self-service markets.

Compared to the relevant state of the art, which identifies several relevant solutions to the problem, the advantages of the device according to the invention are clear, because simple, robust functional parts, which are assigned dual functions, guarantee optimal operational reliability with the use of materials reduced to the achievable minimum.

The functional principle, which is primarily based on the dual function of continuous, ie simultaneous locking and unlocking of the system components coin and key, allows a compact design with minimal dimensions. The invention is explained using an example with reference to the drawings below:: The housing (1) is on the inside on the left and right in the area of the coin level (Fig. I/II) and the

/3

Key level (Fig.III/IV) with mirror-image contours {4). Matched to these housing contours (4), movably mounted and pre-tensioned by the springs (8) in the (upper and lower) mechanical levels {Fig. V), are the contours of the functional parts on the left (2) and right (3), which are also mirror-image contours. Furthermore, the contours of the functional parts (2/3) are matched to the contours of the coupling key (.6) and the diameter of the coin (5). The interaction of the movable functional parts (2/3) with the static housing contours (4) in conjunction with the springs (8), each actuated (moved), i.e. brought into the desired position, by the coin (5) or key (6), results in a coin deposit lock mechanism with technical effort reduced to a minimum for the required, system-compliant function.

Situation: Key In System

The key (6) is in the locking position (Fig. HD (coupling position) via its front recesses, in which the contours of the functional parts (2/3) engage, which are locked via the housing contours (4). This situation is mainly caused by the effect of the springs (8), which act like

are arranged as described above and are in direct operative connection with the functional parts (2/3). When a coin (5) is inserted into the chamber of the coin level (Fig. I), a rotary movement is created via the contours of the functional parts (2/3), which on the one hand releases the key lock (Fig. IV), and on the other hand at the same time creates a locked position for the coin (5) (Fig. I). The system is activated, i.e. ready for use

Situation: Coin in the system

The coin (5) is located in the chamber of the coin level (Fig.II) and is locked by the contours of the functional parts (2/3). This locking is released when the key (6) is inserted by its contours, which trigger a rotary movement of the functional parts (2/3) - at the same time the key (6) is locked (Fig.II). The starting position is established after the coin has been removed (Fig. I/III).
