  • Publication number: 20170138087
    Abstract: A lock structure suitable for various lock cores includes an engagement arranged at one side of a lock core axle of a lock device. The engagement member includes a rod section such that the engagement member is coupled to a link bar. A handle axle includes an arrestor member, such that the arrestor member is coupled to a stop plate and a push bar. A retention member is arranged under the push bar. When the lock core axle is rotated by means of a key, the engagement member and the link bar are driven to achieve locking, or a handle is operated to achieve unlocking. When the lock core is damaged, the damaged lock core is replaceable with one of various types of lock core without the need to replace the entire lock thereby improving the utilization of the lock.

  • Patent number: 8967677
    Abstract: An anti-intrusion lock includes a sliding element at a handle shaft, a stop element under the handle shaft, wherein the stop element is suitable for moving upward or downward, a clamp button and a sliding lever connected to the clamp button, wherein the clamp button is led to be exposed and protruded from a side of the lock. When the lock is locked, the clamp button is pressed down to drive the sliding lever to push the stop element upward such that the stop element is stopped at the handle shaft. Thereby, when a thief turns the handle shaft, only the sliding element is driven to move along a sliding groove set at the lock such that the lock pretends to open and the thief misunderstands the lock has been broken and gives up intruding.

  • Publication number: 20130328324
    Abstract: The locking device contains a latch element and an elastic element. The latch element has a middle bulge and a first bulge and a second bulge to the lateral sides of the middle bulge. The contour of the three bulges is curved. The latch element has a downward extended shaft and two positioning pins vertically extended from the two major faces of the latch element. The elastic element is sleeved over the shaft. The locking device has sliding slots on its casing's front and back faces for the accommodation of the positioning pins, respectively. The latch element is positioned beneath an axle of the locking device's handle. The axle has a notch so that, when the handle is turned to open a door, the middle bulge of the latch element would be embedded into the notch so that the door remains open to avoid its mistakenly closing.

  • Patent number: 8540290
    Abstract: A structure for electrical locks comprises two rotational members, a latching assembly, and a controlling means. The two rotational members are respectively secured to two handles of a door. The latching assembly includes a cartridge, a sliding element, and a dividing rod. The dividing rod is fitted in the cartridge to define two lateral zones respectively corresponding to two recesses of the rotational members. The sliding member is slidably fitted in one of the lateral zones of the cartridge. The controlling means includes a pushing assembly and a solenoid. When the solenoid is de-energized, the pushing assembly can be moved forward to lock a respective handle. When the solenoid is energized, the pushing assembly can be moved back to free the respective handle. The structure can be easily applied in a door where one handle can be freely operated while the other handle can be electro-selectively operated.

  • Patent number: 8366158
    Abstract: A latch direction change structure of lock includes a fixed member and a movable member each having front and rear vertical walls that form through holes and a horizontal connection wall connected between the front and rear vertical walls. The fixed member forms symmetrically arranged slots in a circumference of the through hole of the rear vertical wall thereof. A bar is set through the through hole of the fixed member, receives a spring to fit thereon, and further extends through the through hole of the movable member to attach to a latch. When the latch is frontward pulled with respect to a lock case, the movable member is movable along the fixed member to allow the latch to separate from the lock case for selective rotation of 180 degrees. The slots defined in the rear vertical wall of the fixed member provides a function of properly positioning the latch.

  • Publication number: 20120139267
    Abstract: A cushion structure of lock includes a knob axle, a constraining member, a push bar, and a fixing member. The knob axle forms at one end thereof a pin, which is received in a slot defined in a casing of a lock, and also forms at an opposite end thereof an engagement section, which is positioned in engagement with the push bar. The constraining member is coupled to the push bar and has a surface forming an opening through which a positioning bar fixed to the casing is received. Springs are respectively arranged at a bottom of the constraining member and between the push bar and the fixing member. When the knob is operated to retract the latch bolt, the resiliency of the springs helps driving the constraining member and the knob axle so as to make the rotation of the knob easy and effortless.
