Abstract

A security barrier for resisting unauthorised entry comprises a panel (1) hingedly connected to a first jamb (2) by hinge (6) to the rear of the panel member, and releasable lock at the rear of the panel for locking the panel to a second jamb (3). By providing panel sides which extend to cover the hinge and the lock, access to same is obstructed from the front of the panel. The lock comprises a series of hooks 15, an a slidable bar 13, for engaging cups 16. The bar is lowered by an operating rod (24, Fig. 1 not shown) and secured by a mortice lock (23). Having the first and second jambs in the form of an open mouthed channel member (49, 60, Figs. 12-16 not shown) and providing them with clamping means (44, 64) enables them and hence the barrier to be fitted particularly easily about in situ jambs. <IMAGE>
