Patent DE-2836486-A1 (DE)
IPC: G07F17/14
Filed: 1978-08-21
Abstract: The mode of operation of the lock is as follows: a prescribed coin (18) is to be inserted in order to close the bolt (24). This coin passes into its control position, determined by the driver (49) designed as a change-over pin and by the supporting shoulder (50). The driver (49) of the rocker (42) is a coin support. When the key is turned, the wing (29) of the cylinder plug (30) drives the bolt in the closing-out direction. The coin (18) loads the blocking boss (37) and lifts the latter into a release position. The blocking edge (39) can pass the blocking pawl (35). In the final phase of the forward closure of the bolt, the portion (44) comes up against the stop (52). The rocker (42) and driver (49) remain back. The distance between the supporting shoulder (50) and the driver (49) is greater than the coin diameter. The coin (18) escapes, slides downwards and sits on the supporting strip (55). It simultaneously rolls against the driving pin (51). The forward-closed bolt (24) allows the key to be withdrawn. During the reverse closure of the bolt (24), the driving pin (51) drives the coin (18). It falls into the return compartment (53). The rocker (42) thereby returns to its initial position. This lock is simple in terms of production and is advantageous in terms of use. <IMAGE>

Filed: 1978-10-26
Abstract: The drive comprises two cone pulleys each on the driving and driven shafts, those in a pair turning together and with their respective shaft, on which one of them slides axially. The sliding one forms the rotary cylinder of a piston fixed to the shaft and to which a medium is supplied under pressure controlled by a square-section slide valve coupled to a lever actuated by one of the sliding pulleys. The pulley with fixed support slides, but cannot turn in relation to the other one (18) on its shaft, and forms with a cylinder (19) having a fixed support, a ram unit. In this control piston (22) slides between the inlet for the medium under pressure acting on the other pulley and the outlet, forming inlet and outlet flow control edges (25, 26). The control piston length is such that only the inlet or outlet can be open. The incoming pressure thrusts the piston towards the other pulley in opposition to a spring (28) on the side towards the latter.
