  • Patent number: 11946284
    Abstract: A door lock includes a latch driving device having a thumb turn that can be switched between a locking position not permitting movement of a latch to an unlatching position when an outer handle is pivoted and an unlocking position permitting movement of the latch to unlatching position when the outer handle is pivoted. The thumb turn includes an actuator controlling a switch to a conductive state or a non-conductive state. When the thumb turn is in the locking position, the switch is in the conductive state, and a lighting element controlled by the switch generates light transmitting through the first lid. When the thumb turn is in the unlocking position, the switch is in the non-conductive state, and the lighting element does not generate light. Thus, the locking or unlocking state of the door lock can be identified by sight.

  • Publication number: 20210040770
    Abstract: An anti-torsion door lock includes a lock body having an outer chassis. An outer locking plate includes a threaded hole in threading connection with the outer chassis. The outer locking plate further includes two installation holes and at least one coupling hole which are disposed around the threaded hole. Two installation pegs are coupled with the two installation holes and are coupled to a door, preventing rotation of the outer locking plate relative to the door. An anti-torsion member is mounted around the outer chassis and includes at least one lug engaged with the at least one coupling hole of the outer locking plate, such that the anti-torsion member is not pivotable relative to the outer locking plate. The anti-torsion member is non-rotatably mounted to the outer chassis, preventing the lock body from pivoting relative to the door.

  • Patent number: 9140032
    Abstract: A door lock (3) includes a latch device (30) and an inner operational device (20) mounted to a first side (1A) of a door (1) and an outer operational device (16) mounted to a second side (1B) of the door (1). The inner and outer operational devices (20, 16) can be operated to retract a latch (38) of a latch device (30) from an extended, latching position to a retracted, unlatching position. A tooth (223) on an actuator (219) of the outer operational device (16) breaks if a large force is applied to a handle (197). A spindle (191) pivots freely without moving the latch (38), preventing damage to components of the outer operational device (16) and the latch device (30). A base (811) of the latch device (30) can be comprised of first, second, and third plates (813, 847, 883) to allow sheet metal processing without sacrificing structural strength.
