Abstract: A lock for the locking of a sliding closure. The lock includes a housing (10) with a pair of hook shaped locking elements (11) which are mounted for counter-rotation within the housing. A handle (26) is mounted for rotation on the housing and is coupled to a gear wheel (23) which meshes with a pair of rack elements (30,32) which are located for sliding movement in the housing (10). A projection (34) from each rack element (30,32) engages in a curved slot (35) of the locking element (11). Consequently, rotation of the handle (26) results in a sliding movement of each of the racks (30,32) which causes the locking elements to move between a first position where the locking elements are substantially retracted in the housing (10) and a second position where the locking elements can latchingly engage with a strike.

Abstract: The invention comprises a multiple point latching system for use with postal box clusters. In particular, the multiple point latching system comprises a latch bar, a track member, a plunger assembly and a plurality of latch plates. The latch bar is slidably coupled relative to a center partition in the postal box and includes a plurality of latches thereon.

Abstract: A latch assembly for latching and unlatching a pivotally movable closure panel of an automotive vehicle. A locking lever is pivotally supported by the vehicle for movement between a latched position in which an engaging portion thereof is latched to the striker on the closure panel to hold the latter in its closed position and an unlatched position in which the engaging portion releases the striker to allow the closure panel to be moved toward an open position. A detent lever is pivotally supported by the vehicle for movement between an engaged position in which a stepped portion thereof engages the locking lever to retain the latter in its latched position and a released position in which the first portion thereof releases the locking lever to allow the latter to be moved to its unlatched position.

Abstract: An improved latching apparatus for an access opening cover member or door on a grain bin. When locked closed, the cover member engages the adjacent wall of the grain bin to integrate the cover member with the grain bin wall to thereby enable hoop stresses caused by the weight of grain being stored in the bin to pass through the cover member. Typically, a series of pins carried by the door frame engages openings in the edges of the cover member or door to structurally integrate the door into the bin. The integration of the cover member with the bin wall provides a greater structural integrity of the bin and cover member; however, due to the stresses placed upon the cover member and bin wall, the pins tend to bind, making it difficult to disengage and open the cover member.

Abstract: One side of the operation panel for audio equipment is supported by a projected strip of the audio equipment body and the other side is held by an engagement claw. The engagement claw is pivotally supported on a holder with a spring installed therebetween. The holder in turn is pivotally supported by the end of a first arm whose base end is rotatably mounted on the audio equipment body. The holder is also pivotally connected to a second arm, which is rotatably mounted on the audio equipment body. When the operation panel is moved between the installed position and the pop-up position, a change in the angle between the holder and the engagement claw is kept small by the action of the second arm, so that the spring force acting on the engagement claw does not increase greatly, permitting easy removal or installation of the operation panel.

Abstract: An improvement is provided in an electromagnetic door lock device. The device itself includes an electromagnet in a housing adapted to be connected to the top of a door frame and depend from the underside thereof above a door in the frame. The device also includes an armature block connected to the top of the door in a position near the electromagnet. The armature moves between a down inoperative position away from the electromagnet, facilitated by gravity, when the electromagnet is deenergized and an up extended operative position against the underside of the electromagnet housing when the electromagnet is energized. A locking plate connected to the housing has a tab which depends therefrom and abuts the armature when the latter is in the up position to lock the door closed in the door frame. The improvement prevents slow separation of the armature and tab and hesitant unlocking of the door when the electromagnet is deenergized.

Abstract: A burglar bar assembly for establishing a security barrier across a door or window opening composed of a plurality of horizontal cross bars held in vertically spaced relation by intervening and transversely related vertical members. Certain of the vertical members are fixed rigidly to certain of the cross bars, but slidably joined to others in a manner to provide for extension and retraction adjustment of the barrier to accomodate variations in door or window dimensions. The bar assembly is hingedly connected at one end to a window or door frame to provide for swinging opening and closing operation of the barrier. A safety latch is mounted adjacent one end of the bar assembly and comprises a spring loaded cam member pivotally moveable against spring bias by a remotely operated cable. The cam member serves to capture and lock the unhinged end of the barrier to a rigid locking channel secured to the window or door frame; such channel having spaced angulated slots receptive of the cross bars.

Abstract: An improvement in an electromagnetic door device. The door device includes an electromagnet secured in a housing to the underside of the top of a door frame, a door hinged in the frame for opening and closing therein, and an armature secured to the top of the door for movement betrween a resting position on the door top and an operative position upwardly magnetically attracted to the electromagnet when the latter is energized. In the operative position, the armature is intercepted by a locking plate depending from the housing, so as to lock the door until the electromagnet is deenergized and the armature drops away to the resting position. The improvement is a device which biases the armature upwardly so that it is, in effect, lighter, requiring less electromagnetic force to attract it and permitting the armature to be spaced, in the resting position, a greater distance therefrom for improved door-frame clearance.

Abstract: A positive position indicator that is used on a variety of non-rotatable, cabinet slam-action pawl latches is disclosed. The indicator uses stored spring forces, stored in a thin, twin-leafed flat spring having a plurality of spring bends therein, to react against a latch keeper attached to the cabinet frame. The stored spring forces cause a spring tab to dislodge the latch pawl from an adjacent flat surface and move the latch housing and cabinet door away from the frame.
