Abstract: A motor-vehicle door latch for securing together two relatively movable body parts has a housing mounted on one of the parts, a bolt mounted on the other part and engageable in the housing, a fork pivotal in the housing between a locked position engaging around the bolt when therein and an unlocked position permitting the bolt to enter and exit the housing, a pawl pivotal in the housing between a holding position retaining the fork in the locked position and a freeing position permitting the fork to move between its positions, and an actuating lever engageable with the pawl and pivotal in the housing between a holding position holding the pawl in its freeing position and a freeing position in which it does not impede movement of the pawl between its position. A position-holding element engageable in the housing with the lever is movable between a blocking position preventing movement of the lever of the freeing position and an unblocking position permitting movement of the lever between its positions.

Abstract: An oven door latching system has a latch bolt with a latch arm at one end and its other end pivotably connected to a lever through a resilient connection. The lever in turn is pivotably coupled to a positioning device which has a positioning element which is reciprocatable between spaced positions. When the positioning element is moved, pivotal motion is imparted to the other end of the lever, and the connection enables pivotal motion of the latch bolt. A solenoid acts on the positioning device to move the positioning element between its stable positions and produces concurrent motion of the lever to enable movement of the bolt between an oven door latching position and an oven door unlatching position.

Abstract: A latch retraction device for narrow stile doors which may be hinged either on the left side or on the right side, and which utilizes a push or pull actuator for retracting the latch instead of utilizing a rotary knob for that purpose. The device utilizes inter-engaged toothed elements to provide linear to rotary motion in a novel configuration of parts which permits one set of parts to be utilized to provide either a push or a pull actuation for latch retraction with either a right hand or left hand door and thereby eliminating the necessity to manufacture and inventory a large number of parts to accommodate all four types of desired uses.

Abstract: In order to keep the latched condition of a door lock proper even when the associated door is considerably deformed due to a vehicle collision or the like, the outside lever extending from the door lock proper is provided with a pointed portion which is directed toward an outer panel of the door. Upon deformation of the outer panel, the pointed portion is forced to stick into the deformed outer panel establishing a locked engagement therebetween and thus preventing the door lock proper from taking the unlatched condition.

Abstract: A vehicle door lock system includes a rotary latch having an elongate housing with an end formation that is "inclined" or "tapered" so as to be wedgingly engaged, when "latched," by a correspondingly inclined or tapered wedge block component of an L-shaped striker assembly. As the rotary latch releasably engages the striker to effect "latching," the inclined or tapered end region of the latch housing cooperatively engages the wedge block of the striker to guide the latch into properly aligned engagement with the striker, and to maintain proper alignment of the rotary latch with the striker while "latched." By this arrangement, a strong, racking-resistant type of latched connection is provided that will assist in preventing undesired relative movements of a door and a door frame on which the latch and striker are mounted, respectively. Handle assemblies are connected to the rotary latch to operate the latch to effect "unlatching" of the latch and the striker.

Abstract: A locking mechanism for use in a lightweight safe includes a toothed spur main drive gear mounted on a rotatable axis journaled through the safe's door. The main drive gear mechanically engages a pinion gear which in turn meshes with a vertically disposed rack gear. A second pinion gear also engages the rack gear and further engages a second drive gear. A securement locking mechanism, mounted to the interior face of the safe door proximate the main drive gear, is adapted for cooperation with the main drive gear for detachably restraining the main drive gear in a non-rotative orientation. The pinion drive gear/rack gear arrangement is adapted to transfer motion from the main drive gear around the aforesaid securement mechanism to the second drive gear. Each drive gear is mechanically associated with one or more laterally displaceable rack gears adapted to be displaced into engagement with the safe door frame to produce a locking engagement therewith.

Abstract: A motor-vehicle door latch for use on a vehicle door having a handle and an inside locking element has a housing, a latch fork pivotal on the housing and engageable in a locking position with a door bolt to retain same and lock the door, an actuating lever pivoted on the housing and connected to the handle, a release pawl operatively engageable with the fork to release same from the locking position, and a link displaceable between a position coupling the actuating lever to the release pawl for displacement of the fork out of the locking position by actuation of the actuating lever and a position decoupling the actuating lever from the release pawl. Thus in the decoupling position actuation of the actuating lever will not unlock the door.

The latching mechanism comprises a housing assembly for attachment to the truck body, a rotatable support mounted in the housing and a third lever arm attached to the support and extending from the latching mechanism. An end of the third lever arm is connected to the second lever arm for effecting its movement in response to rotation of the support. First and second stops limit rotation of the support while a tension spring urges the support against the stops.

Abstract: The latch (100) includes a catch (102) having a beveled edge (102A). An aperture (104) receives a downward force to release the catch from the lip (106A) of a housing (106). A stop (108) limits the downward movement of the latch. A retaining tab (110) traps the latch within the door pocket and limits the upward movement of the latch. The retaining tab includes a beveled surface (110A) to facilitate the insertion of the latch into the pocket. A cantilever spring (112) exerts an upward force on the latch when compressed. The latch, including all of its associated parts, can be plastic injection molded in a single-action mold. The door (200) includes a substantially parallelepiped pocket (202) having an opening at the top to receive the latch. The pocket includes a front aperture (202FA) in the upper, front surface (202F) of the pocket, and a rear aperture (202RA) in the lower, opposing rear surface (202R).

Abstract: A door latch mechanism, such as for a calculator battery enclosure, has a pair of ridge and groove mating points. The mechanism has a partially engaged position in which only a single ridge engages a groove and a fully engaged position in which both ridges engage grooves. A shock to the calculator, such as by dropping it, will generally not release the mechanism to a disengaged position. Consequently, the batteries will be retained and memory functions thereby preserved.

Abstract: A gear shift mechanism for a manual transmission includes a shaft axially movable for selecting shift planes and rotatable for engaging the gears defining the shift planes. The shaft is held in a reference shift plane by two helical springs. A finger, fixed to the shaft, carries a cam defining detent surfaces engaged by a spring-loaded catch stud. Shift fork rods support shift forks which have arms formed with grooves extending toward a locking plate that is moved axially along the shaft by the shift finger. The locking plate blocks engagement grooves of the unselected shift forks.

In the armed condition the main bolt member is partly extended and the auxiliary bolt member extends from the end of the main bolt member.

Abstract: A vehicle body compartment is selectively closed by a spring loaded closure panel movable between an open position and a closed position. A latch assembly is mounted on the panel and has a latch bolt spring biased to an unlatched position and normally maintained in the latched position by a key releasable detent lever. A pull down mechanism includes a housing mounted on a vehicle body and a striker mounted thereon by a motorized vertically reciprocating drive unit for moving the striker between extended position and a retracted position. When the panel is moved toward the closed position, the latch bolt engaes with the extended striker to interconnect the panel with the striker. The drive unit is energized and retracts the striker, thereby pulling the panel to its fully closed position. A cam acts between the detent lever of the latch assembly and the housing of the pull down mechanism.
