Lock

摘要

The locks have rectangular housings. The main locking module (1) has a cylinder lock (8) near one end and a latch (7). The locks are fastened to a fixed metal plate or strip (6) fastened to the edge of the door, and there is a catch (4) on the side remote from the main lock. Subsidiary locks (3) are fastened to the strip on either side of the main lock. They are actuated by flat metal strips (2,31) running adjacent to the fixed strip. The subsidiary locks have catches (5) on the other side of the fixed strip and include operating buttons (9).
