ABSTRACT:
Cam operated lock comprises a latch mobile against a spring along a tubular guide. The latch is operated by way of a cam which can be rotated against a spring by a manually operating member, preferably a handle. The handle needs to be turned through only a small angle for opening the lock. The lock can be fitted to both right hand and left hand opening doors with little adaptation, and in both these positions the lock is opened by turning the handle downwards.
