The lock (7) is operable by hand or electrically to move the bars in the same or opposite directions. This allows, e.g. rollers (10) on the inside face (12) of the rigid frame (6) to co-operate with catches. The bars are slidable on a bearing plate contg. similar openings on the inside face (16) and the front edge (17) of the wing (3). Rollers (10) enter the openings when the wing is closed.
