Handle-carried Key Lock Patents (Class 70/221)
  • Patent number: 10246907
    Abstract: The spinning knob includes a shell, a rotation member, and a pushing member. The rotation member is rotatably disposed on the shell. The rotation member includes a threaded portion for screwing with a screw. The pushing member is arranged on the shell and tends to abut against the rotation member to have circumferential interference with the rotation member so that the shell and the rotation member may rotate simultaneously. When the rotation member is screwed to the screw sufficiently and an end of the rotation member abuts against an object, if the shell is further rotated, the rotation member obliquely abuts against the pushing member to make the pushing member trip away from the rotation member so that the pushing member has no circumferential interference with the rotation member and that the shell is rotatable with respect to the rotation member.

  • Patent number: 9528300
    Abstract: A cylindrical lockset comprises a multiple-compartment lock cage subassembly. A retractor is housed within a middle lock cage compartment. Spindle return torsion springs, for biasing corresponding handle-carrying spindles to their default positions, are housed within axially adjacent lock cage compartments. A torque plate transfers torque from the lock cage subassembly to relatively radially distal trim posts. A knob catch assembly seated in each handle-carrying spindle comprises a generally elliptically-shaped wrap around catch spring and a knob catch backup washer to resist axial loads produced by efforts to pull a handle off of the spindle. A key spindle provides a dog travel window defined by a closed, continuous edge of the key spindle, which window is positioned opposite of an axially-extending seam of the key spindle.

  • Patent number: 7793527
    Abstract: A lock includes a handle, a hub, and a spindle rotatably mounted in the hub and coupled to the handle to turn therewith. A transmission member is fixed to the handle to turn therewith. The transmission member is mounted around and not rotatably engaged with the spindle. The transmission member is stopped by the hub after the handle has been turned through an angle, transmitting a torque from the handle to the hub via the transmission member. Thus, impact from the handle can be partly transmitted to the hub and then to a door on which the lock is mounted, instead of completely transmitted to the spindle. Damage to the spindle is, thus, avoided.

  • Patent number: 6973810
    Abstract: A toolbox latch is disclosed having a pivoting handle mounted to a housing and mechanically linked to a pusher arm for setting in motion a series of linkages to trap and release a cooperating striker pin. The pusher arm rotates a swiveling trip lever when a turn-key member is first rotated into an unlocked position and the handle pulled in a pivoting motion away from the housing. The swiveling trip lever in turn rotates a rotating link member out of its locking position with a rotating lock lever, allowing a biasing spring on the rotating lock lever to rotate out of its trap position. The cooperating striker pin is thus freed from the trap position as the rotating link member disengages with the rotating lock lever and the latch is open.

  • Patent number: 6223923
    Abstract: A safety pressure release locking gas cap is shown. The gas cap is comprised of a handle element, and a plug element. The plug element is rotatably housed in the handle element, and has external threads. A lock element is contained between the handle element and the plug element and can be used to lock the two components together. Locking arises by rotation of the lock element, for example by a key, about an axis of rotation which is a first manner of movement. The lock element has also a second manner of movement, which is axially along the axis of rotation. Movement in the second manner moves a valve from a pressure containing position to a pressure relief position. According to the present invention the movement in the first manner occurs independently from movement in the second manner.

  • Patent number: 4637649
    Abstract: A latch mechanism for fastening a hatch panel in an automobile roof opening. The mechanism includes latch pins which extend and retract into and out of engagement with the roof structure to respectively fasten and release the hatch panel. An operator handle can be controlled by a key mechanism to function in either a locked mode or an unlocked mode. In the unlocked mode, movement of the handle to an open position retracts the latch pins, and movement to a closed position extends the pins. In the locked mode, the handle and latch pins are decoupled except upon the first occurrence of the handle being moved to its closed position so as to assure fastening of the hatch panel at all times after the handle is first moved to the closed position.

  • Patent number: 4535613
    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.

  • Patent number: 4527406
    Abstract: A locking fuel cap has a lock bolt which is slidably disposed in the cap handle and responsive to a key-operated lock mechanism to selectively drivingly connnect the cap handle to a ratchet ring. The ratchet ring is connected through a torque limiting drive to a threaded closure. When the fuel cap is unlocked, the lock bolt provides a positive drive in both opening and closing directions. If the fuel cap is locked, a spring finger on the lock bolt engages a pin on the lock mechanism when a predetermined torque is present at the ratchet ring during cap installation. The pin holds the lock bolt in a position preventing a drive connection with the ratchet ring thereafter when the cap is rotated in the opening direction.

  • Patent number: 4309884
    Abstract: A door lock has a flush-mountable body. A forwardly facing recess is defined by the body. A paddle-type handle is pivotally carried by the body and is movable between a nested position within the body recess and an operating position. A spring-projected slide bolt is carried on the back of the body and is movable between projected and retracted positions. A key-controlled disconnect linkage is provided for selectively connecting and disconnecting the handle and the bolt. The disconnect linkage includes an operating member which is pivotally mounted on the body at a location behind the handle, a key-control which is carried on the handle, and a disconnect member which is carried by the key control for movement into and out of driving engagement with the operating member. The operating member has an arm which extends through an opening formed in the back of the body and into driving engagement with the bolt. A two-piece guard shields the members of the disconnect linkage from access by would-be intruders.
