Abstract (en)
[origin: EP0551213A2] A lock (1) is disclosed which is particularly suitable for use on a shopping trolley, for releasably interconnecting with the lock of another similar trolley or with an anchoring point. The lock may, by suitable attachment of appropriate key members (2), be adapted either as a trolley lock permitting "daisy chaining", or as one preventing such "daisy chaining". In the daisy chaining configuration, a free trolley has a loose key which is intended to be used only when the trolley is held at a designated trolley collection point to release a coin key or slide of a newly returned trolley. In the non-daisy chaining configuration a free trolley has no loose key. The described lock has two key holes (6,7) for receiving key members and two separate locking means (4,3) for releasably engaging and securing the key members in the respective key holes. The insertion of one key member releases the other, which can then be withdrawn, such withdrawal causing securing of the inserted key. <IMAGE>
