FIG. (2) shows an anti-barricade door assembly (1) having a door (2) hinged to a door jamb (3) about a first, vertical, hinge axis H1. The door (2) consists of a generally planar, wooden laminated construction, main or central part (2a) bounded by an outer or peripheral, metal (steel) frame part (2b) that extends only around three edges (upper and opposed side edges 2c, 2d, 2e) of main door part (2a) but, importantly, not around the bottom edge (2f), of the main door part (2a). The main or central door part (2a) is pivotably mounted on the outer or peripheral frame part (2b) about hinge axis H2, said door part (2a) being pivotable inwardly, in normal use, about axis H2 to allow access to the interior e.g. of a prison cell. |
