Concealed self-closing door hinge has pressure element operating in a slender box-like housing comprising parallel ears which closely juxtapose the sidewalls of the slot in which the hinge operates. This gives additional support to the door. Various means for restricting the lateral movement of the pressure element are disclosed.

Drawer is supported by system in which drawer side rails are provided with rollers which fit into U-shaped tracks, the rearward ends of which are supported vertically but are permitted lateral movement. Restraining means on the drawer keep the tracks in contact with the rollers. The system forgives errors and discrepancies in the squareness of the structure and inaccuracy of the mounting of rear supports. Also disclosed is a 'wrapping' of the bottom portion of the drawer sidewall by the metal rail obviating glue and other fastening means.

Drawer and support system

Door or window lock

A compact portable lock has a locking plunger angled to fit into a pre-drilled opening in a door or window rail permitting a lock with very minimal clearance requirements with regard to the adjacent frame. A window in the bottom cover plate of the lock accommodates a flange on the lock plunger and defines the travel of the plunger.

Rotary storage unit carries outward lugs. Support surface carries an oblong plastic ring surrounding lug area. Ring is supported adjacent ends of major diameter only. Ring and lugs are dimensioned to forcibly interengage adjacent minor diameter of the ring, distorting the ring. Ring is recessed at ends of minor diameter so that lugs snap into recesses when unit is moved into certain rotary position. This snap engagement serves as a catch for holding the unit in 'closed' position.
