Abstract: One or more panels of similar construction are formed having a frame on a pair of planar decorative faces are secured. The frame is provided with a centrally located groove in its peripheral edges. One or more connecting bars are provided each having plate-like projections fitting into the grooves. The frames and bars are provided with cooperatively engaging means for removably interlocking the panels and the bars together.

Abstract: A door lock, particularly appropriate for a hotel or motel room, which is effectively operated from either the room side or the corridor side to lock the door closed for security purposes, and from the latter or corridor side, additionally is effective to terminate electrical services within the room, e.g. the air conditioner, to thereby minimize the wasteful use of electricity.

Abstract: A partition panel intended for combination with similarly constructed panels in subdividing a room area that obviates prior art difficulties in using cooperating Velcro-identified fasteners. The fastener strip on the panel vulnerable to being inadvertently pulled free thereof upon disengagement of the panels is effectively held thereon by being wrapped about the periphery of the panel; the forces thus are resisted by the longer length of the strip rather than being localized in the smaller portion thereof being separated from the cooperating fastener.
