Locking mechanism having a casing including a pair of spaced support plates of similar size and shape. The support plates have identical, spaced, congruent, T-shaped tongues along their front edges. When installed in a door, the tongues extend beyond the edge to engage a strike in the door frame. A pair of bolt members are pivoted in the space between the support plates and are movable between an extended, closed position engaging the strike to a retracted, open position not engaging the strike. A slide rod engages the bolt members and is rotatably and reciprocally journaled between the plates. The slide rod has a transverse arm portion adapted to be connected to one or more manual locking elements in the vehicle door to turn the rod between locked and unlocked mode positions. A slide actuator lever is pivoted to the casing and is engageable with the slide rod arm portion to turn it between locked and unlocked mode positions. A bolt actuator member is pivotably supported in the space between the support plates and is adapted to be connected to manual opening elements on the inside and outside of the door. The slide rod has an intermediate offset portion. When the slide rod is turned to its unlocked mode position, the offset portion thereof is engageable by the bolt actuator member to move the bolt members to their open position. When the slide rod is turned to its locked mode position the offset portion thereof is not engageable by the actuator member, thereby disabling the slide rod from moving the bolt members to open position when the actuator member is moved.

Vehicle locking mechanism

Locking mechanism having a casing including a pair of spaced support plates of similar or identical size and shape. The support plates have identical, spaced, congruent, T-shaped tongues along their front edges. When the locking mechanism is installed in a door, the tongues extend beyond the front edge to engage a C-shaped strike in the door jamb. A pair of flat-bodied, blade-like bolt members, having shank and latch portions at opposite ends, and pivoted therebetween, are located side by side in coplanar relation in a space between the support plates. The latch portions project outwardly beyond the front edge of the door, between the T-shaped tongues. A flat, eccentric, plate-like cam member is rotatably supported between the shank portions of the bolt members. The cam and bolt members are constrained to a mutually coplanar relation by a sliding contact with the inner surfaces of the support plates on both sides. Manual operation of the cam member by a hand knob or lever moves the latch portions of the bolt between open and closed positions within recesses formed by the T-shaped tongues. In the closed position, they are expanded to engage sawteeth in the strike. In the open position, they are contracted to disengage the strike. When the door is closed, the stems of the T-shaped tongues are swung through an open passageway in one side of the strike, and the heads engage the undersides of the strike making accidental disengagement virtually impossible. Two embodiments are described, one with a rotary cam, and another with a reciprocal cam.

Compact ambidextrous locking mechanism

A door lock comprising a bolt disposed to slide axially in a frame, an outer door handle which includes an actuator extending into a cavity in the bolt, a latch disposed in the bolt cavity to slide laterally of the bolt axis between an unlock position adjacent the handle actuator and a lock position spaced laterally therefrom, and means selectively to position the latch in either the lock or the unlock position.
