摘要
The door or window handle (12) is rotatably mounted in the bore of a boss, which is fixed to the door or window. The handle is normally prevented from rotating by a spring-loaded bolt (15) which engages a hole in the boss. The bolt (15) is attached to a block (32) which slides in a tubular guide which houses the spring (18). A rotary disc (25) is mounted at the outer end of a tubular guide. The disc has a crankpin (21) which fits in one end of a link (20), which has its other end attached to the block. The bolt can thus be retracted by rotating the disc. ADVANTAGE - Reliable single hand operation.
