Abstract: A latch assembly 1 and a latch set 1, 2, 3, 4 for use with a sliding door frame 6. The latch assembly 1 includes a housing 48, 49, and a bolt 17 pivotable relative to the housing 48, 49 on rotation of either one of a pair of actuator hubs 51, 52. The latch assembly 1 also includes a pair of locking hubs, 53, 54 which are also rotatable to adjust the lock mechanism between an active condition and an inactive condition.

Abstract: Vehicles and vehicle systems including locking devices are disclosed herein. In one embodiment, a vehicle includes a front wheel, a steering rack assembly that includes a rack coupled to the front wheel, where the rack extends in a vehicle lateral direction and is translatable with respect to a unibody of the vehicle in the vehicle lateral direction, and a locking device coupled to the steering rack assembly, where the locking device includes a deactivated configuration that allows translation of the rack and an activated configuration that restricts translation of the rack.

Abstract: A lock includes a bolt having latching and unlatching positions, and a locking component having a locking position in which the bolt is prevented from moving from the latching position to the unlatching position, and an unlocking position in which the locking component does not prevent the bolt from moving. A lock cylinder includes a cam having unlocking and deadlocking positions. A deadlocking component has a disengaging position in which the deadlocking component does not prevent the locking component from moving from its locking position to its unlocking position; and when the locking component is in its locking position, an engaging position in which the deadlocking component prevents the locking component from moving. When the cam is in its unlocking position, the locking component is in its unlocking position and a deadlocking component is in its disengaging position, and conversely when the cylinder cam is in its deadlocking position.

Abstract: An apparatus and method for enhancing the security of a cluster box unit which includes a protective enclosure, internal cabinetry, door, hinge and locking system. The cluster box unit may also include outgoing mail compartment doors that are heavily constructed and rigidly reinforced, with the locks carried thereon protectively shielded, and with the extensible bolts of these locks being engaged by brackets that not only lock the outgoing mail compartment doors but also the master loading doors of the cluster box units. The cluster box unit may also include master loading doors are provided with hinges that extend the full height of the doors—hinges that are defined by pivotally interfitting elements of extrusions that very sturdily mount the master loading doors, that prevent prying or bending the doors in the vicinities of their hinges.

Abstract: An anti-theft device for motor vehicles for disengaging the steering wheel from the steering column when the ignition lock is in the locked position. The anti-theft device for motor vehicles includes a shaft. A first end of the shaft is adapted for securely attaching to a steering wheel. A boss is integrally coupled to a second end of the shaft. A well extends into the boss. A rod, having top and bottom ends, is mounted in the well. A biasing means biases the top end of the rod out of the well. A saddle member, integrally coupled to a free end of a steering column, is adapted for receiving the boss. The saddle member has a hole therethrough. The hole is generally located such that the top end of the rod may extend through the hole. A protruding member is mounted to a housing containing the boss and saddle member. The protruding member has a lumen therein. A pin is positioned in the lumen and has a first end and a second end. The first end is extendable into the hole in the saddle member.

Abstract: A closure assembly (20) for engaging a door (14) across the opening (16) of a chamber (12) includes first and second triangular plates (28) and (30) which are pivotally connected to opposite corners of a front face (32) of the door. The plates face each other at the longest sides of the triangles. The remaining sides of the triangles define engagement portions (72, 74, 76, 78). To restrain the door, the plates are pivoted (50, 52) until the engagement portions engage flanges (80, 82, 84, 86) situated around the perimeter of the opening. A seal (96) is then activated to seal the door around the opening. Preferably, a coupling member (33) is coupled to the plates to coordinate their pivoting. Cam slots (114, 116), defined in the coupling member, receive followers (118, 120) connected to the two plates. An operator rotates the coupling member, the followers are cammed or permitted to move by gravity as the plates are pivoted apart and together.

Abstract: A locking mechanism includes a lock cylinder cam urging a split link between which a drive pin engages a generally horizontal slot in an actuator member limited to rectilinear movement with a horizontal pin riding in a vertical slot and engaged in a radial slot in a swinging lock bolt. The split link posts ride in ninety degree arcuate slots with straight horizontal and vertical escape sections at the ends of the slots. Sliding brackets hold a choice of lock cylinders including the slim line types.

Abstract: A hinge-lock security system for preventing relative motion between a door and a door frame.

Abstract: The present invention provides a door lock assembly and method which will provide security for building owners and dwellers and will result in a reduction of property damage and loss by burglars. The door lock assembly includes a tumbler type cylinder which can be rotated by a key from the outside to lock a door or other closure to which it is fitted to a first position whereupon the handle inside the door cannot be used to unlatch the lock from the inside. Also, the door can be locked and thereafter the cylinder can be rotated by turning the key in the reverse direction whereupon the door remains locked but upon withdrawing the key the door can be opened from the inside with the handle. Thus, after locking, the key can be withdrawn in either of two cylindrical positions depending on whether the user wants the door to be able to be opened from the inside by use of the handle.
