<p>A coin-deposite lock to be placed on a trolley being part of a row of mutually connected e.g. shopping trolleys or baggage trolleys comprises a main slide (14) being longitudinally slidable against the force from a spring (16) and a measuring slide (20) likewise longitudinally slidable against the force from a second spring (22). Each of the slides (14, 20) has a transverse central aperture (26, 24), and when a coin (C) of a certain value (diameter) has been inserted between the slides, the apertures (24, 26) are mutually aligned. Upon insertion of a key (8) belonging to the lock in a first key opening (6) in the lock, the slides (14, 20) can be moved to a position (Figure 2), in which a latching finger (36) on a pivotable release member (34) engages in the mutually aligned apertures (24, 26) and retains the slides (14, 20) and the coin (C) between them in a withdrawn position. At the same time, the release member (34) pivots to a position, in which a second latching finger (38) on it frees a second key (12) associated with a previous trolley in the row thus freeing the trolley from the row.</p> |
