  • Patent number: 8844330
    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: 6886381
    Abstract: The invention relates to an actuating device for a lock, especially a lock on the parcel shelf of a motor vehicle, comprising an actuating element (30) and a transmission element (20) which can be moved in a linear manner (20) and on which a catch device (21) is disposed, whereby the movement thereof impinges upon a trigger element (12) which interacts with an actuating rod assembly. The transmission element (20) is embodied as an axially displaceable shaft (20) which can be rotated by means of a central locking device (11) and is provided with an eccentrically arranged extension (22). One area of the actuating element (30) can be rotated by means of a locking cylinder (31) and is provided with an eccentrically arranged extension (32). The front faces (23, 32) of the extensions (22, 32) face each other and overlap in at least one rotational position but not in all relative rotational positions of the extensions (22,32).

  • Patent number: 6865916
    Abstract: A cylinder lock for use in a door lock, comprising an outer plug, an inner plug, a rotary cam adapted to move a deadbolt of the door lock, and a clutch adapted to engage for rotation the outer plug to the rotary cam. The cylinder lock further comprises an electronic blocking device (EBD) and a drive adapted to actuate the clutch upon an unblocking command from the EBD generated upon receiving therein an unblocking signal emitted from the outer side of the door, thereby enabling moving the deadbolt by rotation of the outer plug. The cylinder lock comprises an inner handle attached thereto at the inner side of the door, the EBD and the drive being entirely accommodated within the inner handle. The signal is emitted by an electronic key or panel and may be a mechanical vibration signal, a light signal, or a radio signal.

  • Patent number: 6834520
    Abstract: A dead bolt lock apparatus specifically adapted for use with a flight deck door of an aircraft. The apparatus includes a dead bolt member which can be moved between locked and unlocked positions via a key. A lockout handle is included on the side of the apparatus which faces the flight deck area of the aircraft. The lockout handle is movable rotationally from a first position, wherein it has no affect on the use of the key to unlock the dead bolt, to a second position wherein it prevents the dead bolt from being moved out of a locked position by use of the key. The apparatus thus provides an additional degree of security to occupants of the flight deck by allowing them to prevent unlocking of the apparatus even with the key.

  • Patent number: 6832500
    Abstract: An electric door lock includes a lock housing, an operating member, a gear wheel, an actuating member, a driving motor, and a coupling unit. The operating member is mounted rotatably on the lock housing. The gear wheel is sleeved rotatably on the operating member. The actuating member is secured on the operating member so as to be co-rotatable therewith. The driving motor drives rotation of the gear wheel. The coupling unit interconnects the gear wheel and the actuating member such that the actuating member and the operating member rotate with the gear wheel when the driving motor drives rotation of the gear wheel, and disconnects the actuating member from the gear wheel when a rotating force is applied directly to rotate the operating member such that rotation of the actuating member with the operating member does not result in corresponding rotation of the gear wheel.
