ABSTRACT:
The invention relates to a coin lock device having a housing, a protruding element extending from said housing and an aperture in the housing for the reception of a protruding element of an identical lock device.
A key element is secured to one end of a slide piece which slides against the action of a spring, which slide piece is connected at the other end with a cylinder core having movable, transversely disposed tumblers. The cylinder core slides in an aperture in the housing and is movable under the action of the return spring of the slide piece to a rest position. In the rest position the tumblers engage apertures formed in the surface of the aperture receiving the cylinder core, out of which they can be pushed by the introduction of a key element of a second identical device into the cylinder core.
An ejector movable against a spring is provided in the housing to effect release of the cylinder core and hence disengagement of locking device between the device and an adjacent identical device on insertion of a coin. The ejector also serves to release the coin on introduction of a key element of another device into the cylinder core.
