    • 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.
    • 本发明涉及一种具有壳体的硬币锁定装置,从所述壳体延伸的突出元件和壳体中的孔,用于接收相同锁定装置的突出元件。 一个关键元件被固定在滑动件的一端上,该滑块抵抗弹簧的作用而滑动,该滑块在另一端连接有具有可移动的,横向布置的制动栓的气缸芯。 气缸芯在壳体中的孔中滑动并且可在滑块的复位弹簧的作用下移动到静止位置。 在静止位置,滚筒接合形成在接收气缸芯的孔的表面中的孔,通过将第二相同装置的关键元件引入气缸芯中,它们可被推动。 能够抵靠弹簧移动的顶出件设置在壳体中以实现气缸芯的释放,并且因此在插入硬币时在装置与相邻的同一装置之间脱离锁定装置。 喷射器还用于在将另一装置的关键元件引入气缸芯中时释放硬币。
