Abstract: A door lock bracket for serving as a striker which secures an automobile door closed in conjunction with a door latching assembly. The door lock bracket is formed from a one-piece stamping which includes a flange portion for mounting the door lock bracket to the door post of the automobile, an apertured portion for receiving the door's latching mechanism, and a base portion interconnecting the flange and apertured portions. The door lock bracket is structurally uncomplicated, so as to facilitate the manufacture of the door lock bracket using a relatively simple multiple-step bending operation. As a result, the door lock bracket is relatively inexpensive to manufacture, yet can be formed to be strong and structurally rigid for extended and repeated use throughout the life of the automobile.

Abstract: A cover for a housing is maintained in a fixed position with respect to the housing by a latch arrangement that has at least one edge surface disposed along one edge of a flange which engages a mating surface on the housing when the cover is assembled with the housing. The other side of the flange is integrally formed with an elongated beam that is attached to the cover structure. The elongated beam is torsionally loaded upon assembly of the cover with the housing, and provides a bias force on the edge surface of the flange to maintain the forcible engagement of the edge surface with a mating surface of the housing. The latch arrangement combines the cost effectiveness and space efficiency characteristics of plastic latch designs with the durability, dependability and tactile qualities of mechanical spring arrangements.

Abstract: A door opener wich can be used for closed-circuit current operation as well s for working current operation, includes a door latch and a trimmer which can be moved for blocking and releasing the door latch, an armature which can be displaced for blocking or releasing the trimmer, an electromagnet for displacing the armature, whereby the armature can be moved between three consecutive armature positions, namely a first armature position, a second armature position, and a third armature position. The armature positions alternately provide a locking and releasing of the door latch. The door opener also includes a stop element, which can be displaced for delimiting the displacement path of the armature between a first stop position and a second stop position such that the first or third armature position is blocked.

Abstract: A steering wheel lock including a lock body, a U-shaped shackle bar mounted on the lock body for securing to the lock body to the rim of the steering wheel to be locked, a hook bar integral with the lock body for hooking on the rim of the steering wheel, and a polygonal stop bar fixed to the lock body for stopping at a fixed location inside the motor vehicle, the polygonal stop bar having square drive ends at both ends for use as L-shaped wrench means for turning bolts and nuts by means of sockets.

Abstract: A motor-vehicle door latch has an input lever pivotal by an inside door handle about an axis and an output lever connected to the latch mechanism and pivotal about the axis between an actuated position corresponding to a door-unlatched position and an unactuated position corresponding to a latched position. The input lever is formed with a straight slot extending radially of the axis and the output lever is formed with an L-shaped slot having one leg extending generally radially of the axis and alignable with the slot of the input lever and another leg.

Abstract: A device is adapted for use primarily as a theft deterrent for bicycles, mopeds and other two and three wheeled self propelled or motorized conveyances, said device comprises a pair of opposed, telescopically engaging U-shaped members and locking means associated with said members, securing them from being forcibly pulled apart. The locking means typically includes the use of a pawl and ratchet arrangement for facilitating the engagement of the two members for securing them in locking relationship. The device also includes a compressible and extendible rubber or elastomeric boot preferably in the form of bellows. This boot provides a protective cover around ratchet teeth that are longitudinally spaced along one of the arms of the two U-shaped members. The boot progressively surrounds the ratchet teeth as the rod is disengaged or withdrawn from the sleeve.

A pivotal member is received in the body and has a rod extending from a first end thereof to alignedly contact with the hook-like latch when it is pivoted. A symbol-sequence selecting device is received in the body to cooperate with the pivotal member. The symbol-sequence selecting device is operable at two sides of the padlock. The padlock further includes a release member movably mounted to a surface of the first casing to activate a pivoting of the pivotal member.

Abstract: An automatic door latch has a case and a bolt movable within the case between a fully extended position in which the bolt extends forwardly of the case and a partially extended position in which the bolt is positioned to contact a door strike. There is a plunger mounted on the bolt, with the bolt and plunger being relatively movable. A spring biases the bolt toward a fully extended position and a spring biases the plunger outwardly of the case. The plunger has a projection which limits outward movement of the plunger to a position in which its extension is the same as that of the bolt when it is in its partially extended position. There is a stop on the bolt movable toward and away from the case and there are projections on the case which coact with the bolt stop to limit bolt extension to its partially extended position.

A rear portion of the trigger is spaced from and in opposed relation with a portion of the firearm frame. The plug includes a base portion having a size and shape corresponding generally to one of the lateral openings. The plug also has a trigger-blocking projection extending from and positioned generally at one end of the base portion. The trigger-blocking projection defines a lock shackle-receiving bore. A tang extends from and is positioned on the base portion and in opposed relation with the first or trigger-blocking projection. The trigger-blocking and tang define a recess of a size and shape corresponding to a trigger.

Abstract: A security door assembly or locking mechanism for securing a single door in locking engagement with an adjacent door jamb structure comprises a first elongate metal blade to be received by a matching elongate groove in a vertical edge of a door. A second elongate metal blade is received by a matching groove in an upper horizontal edge of the door. Mechanical devices are provided for moving said blades partially from the grooves in the door into engagement with receiving grooves in the adjacent door jamb structure to lock the door. The vertical and horizontal blades are coupled together by a linkage mechanism which enables both blades to be operated simultaneously upon actuation of a single lever or knob. The blades and the linkage mechanism are mounted in an L-shaped housing inserted into grooves formed in adjacent edges of the door. Elongate metal strips are provided to be mounted over the grooves in the door jamb.

Abstract: Locking devices for locking two components that move relative to one another such as a housing and a cover are disclosed. The locking devices have two catches disposed on one component and opposite to one another and symmetrically with respect to a stop disposed on the second component and arranged in a plane of symmetry between the opposing catches. The catches have hook ends facing the plane of symmetry and the two catches are connected to a common shaft at the ends of the catches facing away from the hook ends. The common shaft is disposed in the plane of symmetry and is movable within the plane of symmetry toward and away from the stop. The shaft is arranged on a spindle disposed in the plane of symmetry or parallel to the plane of symmetry and engaged with a motor-driven gear to effect movement of the shaft. The catches have longitudinally-extending guide elements whose longitudinal axis does not run parallel to the plane of symmetry.
