Abstract: A lock mechanism is disclosed for use with sliding, swinging or overhead doors. A receiver is affixed to the door frame and a bolt, linkage and handle are affixed to the door. The linkage allows the bolt to engage the receiver by sliding along the receiver until it becomes latched so that the door may be closed though the handle is locked. Pulling upon the unlocked handle retracts the bolt from the receiver and also causes the door to start opening.

Abstract: A hardware assembly, which is readily adaptable to luggage cases of widely varying constructions, dimensions and configurations, includes a housing which may be positioned within cut-outs in adjacent edges of the side walls of the luggage case, and be mounted on the exterior of one side wall. The housing contains slideable latches for engaging associated hasps mounted on the exterior of the other side wall, and a flexible member connecting the latches to a slideable actuator mounted on the housing for opening the case. The coupling between the latches and the flexible member allows the latches to move to unlatching position independently of the actuator to facilitate closing and latching of the case when the parts are brought together. The actuator is U-shaped and supported for transverse movement on the housing by a rocker located within the housing.

Abstract: A cable release and latch for a security guard hinged to a window or the like has a spring loaded plunger swedged into an outer frame thereof. An armored cable with a flexible inner cable is connected to the spring loaded plunger and extends to a foot treadle operator and shield which may be mounted on the floor inside the opening. Sufficient length of cable is provided to allow free movement of the guard about its hinges. The security guard may thereby be quickly and easily opened without a key by stepping on the foot treadle operator. If the armored cable is severed, the spring loaded plunger advances further into the keeper which retracts the flexible cable within the armored housing to prevent the manual operation of the latch without further dismantling of the cable.

Abstract: Latching apparatus with anti-separation feature for use with closure covers, such as vehicle doors, including interlocking back plate of bolt and striker, the back plate being mounted on the door and having a flange at the outer end which engages behind the striker mounted on door frame, when in closed and latched position, and an aperture adjacent the outer end of the bolt to accommodate an outwardly extending tang on the edge of the striker which is lockingly engaged by the bolt, with a spacer between the striker and door frame to enable such engagement of striker by back plate flange, thereby assuring three-directional containment of the striker so as to prevent undesired separation of bolt from striker because of relative movements therebetween.

Abstract: The invention relates to a safety latch assembly for a warehouse type door that has rollers riding in a vertical guide track, such track having latching holes at various points along its length. The latch assembly has a latch pin with a roller end spring biased toward the track, and rides on the track with the door until it comes into latching engagement with one of the aforementioned holes, and locks the door into its current position. Withdrawing the latch pin from the hole resets the bias spring as the door becomes unlocked.

Abstract: A lockable gas tank cap device comprises a cover hingedly affixed to a vehicle in the area of the open end of a gasoline tank of the vehicle in a manner whereby it covers the open end in a closed position and is free from the open end in an open position. A spring-biased pin is biased by a spring and slidably mounted on the vehicle in proximity with the cover for locking the cover in closed position under the force of the spring. A cable is affixed to the pin and extends into the vehicle for moving the pin against the force of the spring to release the cover for movement to its open position.
