  • Patent number: 8449005
    Abstract: A cylindrical lock includes a retractor (131) mounted between inner and outer operational devices (10, 12) and operably connected to a latch (779). The outer operational device (12) includes an outer chassis (305), an outer lining (353) mounted around the outer chassis (305), and an outer spindle (379) received in the outer chassis (305). The outer spindle (379) includes an inner end (391) received in a pivot hole (375) of the outer lining (353). A restraining protrusion (397) is formed on an outer periphery of the outer spindle (379) and abuts an abutment face (376) of the outer lining (353), avoiding movement of the outer spindle (379) away from the outer chassis (305) in a longitudinal direction while allowing pivotal movement of the outer spindle (379) in a correct position.

  • Patent number: 8430436
    Abstract: An antio-ligative ergonomic type door-knob primarily of the institutional type, essentially serving to defeat the effort of a temporarily mentally-depressed room occupant from succeeding in committing self-hanging via contrived ensnaring by which to secure a cord like hanging-noose. Generic-variant embodiments of my anti-ligative doorknob are set forth, including both a circular and semi-circular ecutcheon-plate for I-shaped V-shaped Y-shaped X-shaped fin-levers, and also a non-finned hemispherical iteration. The novel critical minimum approximate 40-degree anti-ligative principle of my LIFESTAR™ doorknobs reliably prevents a person ensnaring any heretofore problematically hazardous to portion of the door-knob assembly, while my optionally cooperating door latchbolt is formed to a matching critical minimum approximate 40-degree anti-ligative tri-beveled latchbolt as well.

  • Patent number: 8360489
    Abstract: A cylindrical lever lock using a lever as a handle for convenient use by even the disabled and the old is disclosed. Since plate shafts, spring holders and spring cage covers constituting the cylindrical lever lock are made of general metal plates, the material cost and the prime cost may be reduced. In addition, the spring holders are connected through double engagements with spring cages and the spring cage covers. Therefore, deformation of parts or drooping of levers may be prevented in spite of an excessive force applied. Furthermore, assembling and disassembling of the parts can be quickly and easily performed by achieving adjustment of intervals of the parts according to thickness of a door using a female screw of an outer attachment plate and a male screw of a boy assembly.

  • Patent number: 8215685
    Abstract: A double slide arm spring mechanism for biasing a primary mechanism to home position after operation and retaining the primary mechanism in the home position pending further operation. The double slide arm spring mechanism includes a pair of slideably interlocking arms each having a longitudinal frame member and a spring engaging flange at each end. The frame members are a disposed to engage one another while permitting relative sliding of the arms. The slide arms are interlocked such that one flange of each arm is situated between the two flanges of the other arm. Two compression springs are retained between the flanges of the arms such that sliding of either arm toward the other necessarily compresses both springs. Potential energy stored in the springs returns the slide to its neutral position when the operator is released thereby also returning the operator to its neutral position.

    Abstract: The resilient device contains two intermediate plates stacked and sandwiched between two outer plates. The intermediate plates have a center opening for accommodating a rotational seat and a spiral spring in the gap between the rotational seat and the intermediate plates. The ends of the spiral spring are attached to the rotational seat and the intermediate plates, respectively. An axle of a door knob or a door handle runs through the outer plates and engages a saw-toothed center opening of the rotational seat. When the door handle or door knob is turned, the spiral spring is tightened as the rotational seat is turned along with the door handle or door knob. When the door handle or door knob is released later, the spiral spring expands and therefore restores the door handle or door knob back to its original, un-turned state.

    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.

    Abstract: The invention proposes a latching device for at least two housing parts, in which a snap-on connection as well as a latching connection between the housing parts is produced by means of a correspondingly designed rotary knob/pushbutton function. To this end, an actuating button preferably is respectively arranged on two opposing sidewalls of an upper housing part, wherein said actuating button respectively acts upon a spring lever that is arranged on the inner wall of the upper housing part. During the assembly of the upper housing part and a lower housing part, a forced snap-on connection between the two housing parts is produced and can only be disengaged again by exerting pressure upon the actuating buttons on both sides. If the actuating buttons are turned by 90° when they are snapped together, the two housing halves are latched to one another by means of a correspondingly designed mechanism and initially cannot be separated from one another.

  • Patent number: 7401484
    Abstract: A handle, housing and cover assembly includes an relatively thick oval handle sandwiched between a relatively thin oval housing base and a relatively thin oval cover. The oval exteriors of these three relatively movable components are of substantially the same size and shape, and align when the cover is closed and when the handle is in its normal, non-operated position to provide a low profile stack of components that can nest comfortably within the palm of one's hand so the palmed cover can be moved by gentle hand pressure between closed and open positions, and so the handle can be pivoted by fingertip pressure between non-operated and operated positions. The cover, when open, provides access to a keyway into which a key can be inserted and turned to selectively prevent and permit turning of the handle relative to the housing base.
