<p>For use in variable-position partition walls made up from a series of movable wall elements, pref. with top and bottom extensible and retractible sealing battens, the wall element provides a swivelling door for passage. There is a stop, in the form of locking pin (27) or locking hook, bolting the door (20) in the closed position on the wall element, separately from any eventually fitted door lock or latch. Its setting can be dependent on the setting of the sealing battens, so that it locks when these are retracted, pref. activated by the same mechanism. This increases security when the wall elements are manipulated.</p> |
