<p>A desk (10) including a number of drawers (12), each drawer (12) being spring loaded and slidable into closed positions. Electrically actuable locking mechanisms lock the drawers (12) in the closed positions. Each drawer (12) can be maintained open, against the spring closing action, by a drawer catch which is both manually and automatically (electrically) releasable. The desk (10) includes a pseudo intelligent control mechanism which will operate the drawer catches and locking mechanisms so that, under certain predetermined conditions, the drawers (12) will be automatically closed and locked. Amongst those predetermined conditions for closing and locking the drawers (12) are (a) the sensing of a predetermined authorised person leaving the desk and (b) the sensing of movement of a drawer (12) when conditions indicate that the drawers should remain closed. The desk (10) includes an infra-red rim (13) for providing infra-red communication between the desk (10) and surrounding, similarly equipped furniture and radio frequency tags to be worn by authorised persons.</p> |
