ABSTRACT:
A domestic security closure in a form of a cabinet having a front opening (9) defined at the top of a framework (2) partially embedded in the floor and providing a guide for a pair of rigid steel doors (10,12) which can be lifted by use of a counter-weighted chain drive system (20,21,24,25) from a retracted position below floor level (8) to a raised position in which they are locked in place securely to close the cabinet, for instance using a mortise deadlock (29) and a locking bar (27). The flush floor enables entry of relatively bulky and valuable items without lifting.
