PCT No. PCT/EP90/00593 Sec. 371 Date Nov. 28, 1990 Sec. 102(e) Date Nov. 28, 1990 PCT Filed Apr. 17, 1990 PCT Pub. No. WO90/13098 PCT Pub. Date Nov. 1, 1990.A coin slide (11) bearing a coin is movable into a casing (2) of a coin lock (1) to release a locking member (14) and allow full insertion of the coin slide (11). In this position a space (recess 20) in the coin slide (11) is aligned with a space (aperture 21) in a coupling member (8) and with a space (aperture (19) in a casing position separating the coin slide (11) and the coupling member (8). A locking member (e.g. ball 18) in the apertures (19 and 21) may now be moved upwardly, on pulling of the coupling member (8), to occupy the recess (20) and the aperture (19) so as to allow complete withdrawal of the coupling member (8), e.g. to free a shopping trolley. The coin is released by reversing the procedure on re-insertion of the coupling member (8). |
