Abstract: A reach out lock for a sliding door is disclosed. The reach out lock includes keeper having a keeper latch and a locking mechanism having a hook to engage the keeper latch. The reach out lock further includes a mechanism which prevents actuation of the locking mechanism if the locking mechanism is out of alignment with the keeper.

Abstract: Latching apparatus for first and second adjacent swinging doors prevents locking of the first door unless the second door is latched and prevents unlatching of the second door unless the first door is open.

Abstract: Two screws are threaded into two holes in a hinge arm which is adapted to be assembled with a base plate by shifting the arm longitudinally to cause the screws to slide into two U-shaped slots in the plate, the slots permitting longitudinal adjustment of the hinge arm. One of the screws may be turned to adjust the inclination of the hinge arm relative to the base plate while the other screw serves to lock the arm to the plate.

Abstract: A concealed self-closing hinge for mounting a door on a frame. The door member of the hinge includes a cup formed with vertically aligned slots. The frame member of the hinge includes an arm whose free end is formed with integral pintles which are pivotally received in the slots. A plastic cam is adapted to be slipped onto the free end portion of the arm between the pintles and coacts with a leaf spring to hold the pintles in assembled relation with the slots and also to effect self-closing of the door.

Abstract: A hinge for an inset cabinet door includes door and frame wings which enable the door to be adjusted both horizontally and vertically relative to the surrounding face frame of the cabinet. An angled wall of the frame wing enables a locking screw to be driven into the frame at an angle by a power-operated driver without the driver being obstructed by the adjacent side panel of the cabinet.

Abstract: A concealed hinge with a door member having a cup which fits into a pocket in the inner face of a cabinet door, the door member and the cup being molded of plastic. Two cantilevered spring fingers are molded integrally with and are located in the cup. As the door is swung closed, the spring fingers coact with a cam on the frame member of the hinge to effect self-closing and self-latching of the door.

Abstract: The sash of a roof window is swung between closed and open positions in response to the extension and retraction of a pair of pivotally supported crossed arms which are adapted to be swung by an operating mechanism whose mechanical advantage increases as the sash moves from its closed position to its open position. The increasing mechanical advantage of the operating mechanism offsets the decreasing opening force exerted by counterbalance springs during opening of the sash and enables the sash to be opened through its entire range with relatively constant manual effort. The initial preload in the counterbalance springs may be selectively adjusted to compensate for the weight of a particular sash and the pitch of a particular roof.
