  • Publication number: 20160130837
    Abstract: A lock assembly includes a tube, a knob connected to the tube, a dismount mechanism including an engaging component that is movably disposed in the tube, and a lock unit mounted in the knob. The lock unit includes a rotor engaging the engaging component for preventing the lock unit from being dismounted. The rotor is rotatable between a first angular position, where the rotor prevents movement of the engaging component, and a second angular position, where the rotor allows the engaging component to move. The rotor is disengaged from the engaging component when the engaging component moves to a disengaging position, such that the lock unit can be dismounted from the knob.

  • Patent number: 8584495
    Abstract: An exchangeable cylinder lock includes a plug shell connected to a pin chest. A locking pin is disposed in a radial pin hole in the pin chest and is biased to protrude from an aperture in a cover plate and to engage a lock housing. The locking pin is depressable to retract for disengaging from the lock housing. A locking ring is disposed around the plug proximate to the locking pin, and has at least one indentation. When the plug is rotated using a right key, the locking ring can be rotated to align the indentation with the locking pin so as to permit depression of the locking pin, or to move the indentation away from the locking pin so as to prevent depression of the locking pin.

  • Publication number: 20110289987
    Abstract: In a door lock assembly, a push/pull handle is connected to a slide plate through an actuator. When the handle is operated, the actuator drives a rotary cam to rotate a spindle tube, which in turn operates a latch cam connected to a latch. The slide plate is mounted movably within a housing in proximity to the rotary cam to slide transversely of a rotation axis of the spindle tube, and has two drive elements to respectively drive two driven elements of the rotary cam. The actuator is formed as a strip having one end connected to the handle, and another end connected to the slide plate. The strip is pivotal along with the handle to actuate the slide plate.
