Abstract: A door knob construction featuring a machined knob and cover to incorporate decorative detail. The knob construction consists of a knob body, a shank threadably connected to the knob body and a cover which fits over the shank to complete the decorative knob assembly. The knob body is hollow to accommodate the lock cylinder and includes a small diameter hole through which the cylinder protrudes. The back of the knob body includes threads to accept the knob shank. Upon assembly, a bore is drilled across the threads and a pin is inserted to prevent disassembly of the knob body from the shank. The shank includes longitudinal ridges to form an interference fit with the decorative shank cover.

Abstract: A locking handle for an access door includes a housing with a cam rotatably mounted within the housing. The cam is connected to a locking pin for the pin to move transversely in response to rotational movement of the cam. A locking bar is slidably received on the housing and moved to a locked position to prevent rotation of the cam.

Abstract: A trigger latch for mounting in an opening in a door for releasably latching the door to a door frame and having a housing, a handle, a bolt, and a shaft rotatably mounted in the housing and non-rotatably mounted in the handle and in the bolt for rotation of the bolt by the handle between a latch closed position and a latch open position. The shaft preferably comprises first and second drive bushings, each having a circular section rotatably mounted in the housing, a first non-circular section fixedly mounted in the handle, and a second non-circular section fixedly mounted in the bolt, with the first drive bushing have a pin projecting from the inner end and the second drive bushing having a passage therethrough for receiving the pin and joining the bushings together.

Abstract: There is provided a door locking handle assembly in which a bearing (6) is provided in a base member (3); a shaft (7) mounted in the bearing (6) is fixed to a handle (4); a lock lever (5) is fixed to the handle (4); a latch casing (18) is fixed to a front of the handle (4); a lock unit (23) is mounted in a lock-receiving portion of the handle (4); a receiving portion (32) engaged with and disengaged from a dead bolt (46) of a latch (27) in the casing (18) is formed in a front of the lever (5); and, stoppers 14 and 15 of opposite ends of the lever (5) are engaged with grooves 16 and 17, respectively; whereby a fear of overlooking an unlocked condition of the handle (4) is eliminated; and, since torque from the shaft (7) is dispersed and received through the stopper mechanism (14, 15, 16, 17), a fear of deforming the unit (23) is eliminated even if the assembly is subjected to such torque in its locked condition.

Abstract: A mounting hub is arranged for securement orthogonally relative to a steering wheel shaft, such that the mounting hub includes a lock cylinder arranged for rotation of an actuator rod arranged to effect rotating a cam member to project a plurality of lock plates from within an extension tube of the mounting hub for reception of the lock plates within complementary cavities of a steering wheel tubular hub to lock the associated steering wheel relative to the steering wheel shaft.

Abstract: A window having a lock. A catch is provided at one of double sliding windows, and a latch is provided at the other double sliding windows so as to be rotatable and so as to be engageable with the catch. The latch prevents movement of the double sliding windows when the latch is engaged with the catch. A combination padlock prevents rotation of the latch when the latch and the catch are engaged. The combination padlock is locked and unlocked by combinations of positions of a plurality of dials.

Abstract: A transverse retaining plate in the lever handle shank fits in a circumferential groove on the inside of the handle body and holds the lever handle on the shank. A key cylinder in the body handle has a bible which fits in a longitudinal slot in the handle. A resilient block is disposed in the slot in a position between the bible and the shank hub to hold the cylinder in position. The block also serves as a spring, biasing the retaining plate toward the groove.

Abstract: This disclosure is directed to a key-activated, handle-operated three way (position) locking mechanism for removable automobile, or other vehicle, roof panels of the type wherein the handle customarily pivots from locked to open (unlocked) positions to permit removal of the roof "T-top" panels. The "T-top" lock-handle device of this invention comprises a latch stud adapter mechanism and locking cam mechanism each located substantially within a handle-housing and operative to permit locking and unlocking over a three position arc for the lock and a two position arc for the handle-housing and wherein unlocking is effected by meshing of notched surfaces on said adapter and locking cam whereby the locking cam drives the adapter upon rotation of the handle to unlock the "T-top" permitting its removal from the automobile roof.

Abstract: A lock for a vehicle sunroof panel including a handle for effecting rotation of the shaft and parts mounted to the shaft and handle cooperable by positioning of one relative to the other by means of a key-operated lock cylinder to on the one hand enable the handle and on the other hand to disable the handle.

Abstract: A paddle handle lock bolt includes a bellcrank retractor or trigger member which constitutes the central element of a three element drive train comprising a paddle handle, the bellcrank retractor, and a spring-loaded slide bolt. The bellcrank retractor can be selectively coupled to the paddle handle for selectively drivingly engaging the spring-loaded slide bolt in the retracting direction.

Abstract: A door lock for motor vehicles, in which a lock cylinder is connected with a lock tumbler by way of an insertable entrainment rod, whereby the lock cylinder is inserted together with a door handle into an aperture provided in the outer body panel of the door; an anti-theft device which is connected with the lock cylinder, engages from behind a locking projection provided at the door.

Abstract: A lever arm lock for a conventional quick-release hub assembly includes a cover mountable to a first skewer rod end nut supporting a quick-release lever arm. The cover is secured to the end nut with a locking mechanism (combination, magnetic, key, etc.) and maintains the lever arm in a locked position making it impossible to remove the hub. A second skewer rod end nut opposite the first end nut is formed with a substantially smooth outer surface that is continuously inclined with respect to the axle. This surface configuration prevents removal of the locked hub assembly by turning the second end nut with a pliers or other tool. The lever arm lock also prevents the hub from being jarred loose on impact with curbs, rocks, etc. The end nut assemblies have extensions which abut the frame thereby preventing loosening thereof for unauthorized removal.
