Bolt Type Patents (Class 70/71)
  • Patent number: 9435148
    Abstract: A latch bolt mechanism for tilting window sashes includes an actuating spring that is integrally molded of plastic material in one piece with the latch bolt. The spring has a transversely corrugated configuration, comprised of at least two transversely disposed wave-like spring sections. Each spring section includes a pair of oppositely oriented U-shaped sections having spaced apart semi-cylindrical portions at opposite sides joined by transverse connecting sections. In a relaxed configuration of the spring, the several connecting sections are substantially parallel to each other and are longitudinally spaced apart. In a compressed configuration of the spring the connecting elements lie at an angle to each other and the several semi-cylindrical portions are closely spaced or in contact providing for the required spring compression without excessively stressing the plastic material. Significant production economies are realized with the one-piece, molded construction of the latch bolt and spring.

  • Patent number: 7825811
    Abstract: A locking device comprising a lock body having a through hole, a bolt member having a longitudinal bore therethrough and an insertion end which is inserted into the through hole of the lock body. The bolt member is further having a retaining pin disposed within the longitudinal bore and a resilient means for biasing the retaining pin axially out of the longitudinal bore. When the bolt member is inserted into the lock body, a means within the lock body prevents the removal of the inserted bolt member therefrom, and engages an actuating means to actuate an identifying means. The identifying means transmits a signal to indicate whether the locking device has been tampered with or defeated. If the bolt member is cut, the retaining pin is displaced out of the longitudinal bore and dislodges the actuating means resulting in the identifying means indicating that the locking device has been tampered with or defeated.

  • Patent number: 6462965
    Abstract: A switching power supply which includes a sychronous rectifier circuit that performs sychronous rectification with a main switching element by using rectifying switching elements. When a current begins to flow into the rectifying switching element 6, the rectifying switching element 6 builds up rapidly by the voltage induced in the auxiliary winding 21 of low impedance. Accordingly, the rectifying switching element 6 turns on rapidly at a point showing an approximately maximum current so that the ON-state resistance of the rectifying switching element 6 can be smaller. The voltage induced in the auxiliary winding 21 is fed directly as a drive signal of the rectifying switching element 6 so that the drive signal is not influenced by an output voltage.

  • Patent number: 6418760
    Abstract: A mechanism for converting between rotational and linear movement includes a rotatable hub structure and a striker element having an inboard end and an outboard end. In one form of the mechanism, a pivot/spring structure is positioned to engage a pivot location on the striker element between the inboard and outboard ends of the striker element. The pivot/spring structure provides a deflectable pivot fulcrum which can be deflected from a pivot rest position in response to a deflecting force exerted on the striker element. The hub structure can be engaged with the inboard end of the striker element so that a rotational movement of the hub structure provides a force on the striker element tending to cause the inboard end to pivot about the pivot structure, deflecting the pivot fulcrum such that the outboard end of the striker element moves in a generally axial direction. The mechanism can be used in a latch.

  • Patent number: 5507161
    Abstract: The invention is a device for locking the closure mechanism on an item of luggage. The device includes a movable rod which drives a movable clasp bolt on one part of the luggage. The clasp bolt interacts with an opening in another part of the luggage, which opening serves as the strike for the clasp bolt. A movable latch may be interposed in the path of the rod, so that in an active position the latch blocks the movement of the rod, thus locking the case, but when the latch is in a retracted position the rod is released. The latch is moved by an electric motor connected to the latch by a gear reduction unit which amplifies the output torque of the motor. The latch may remain in its blocking position when motor torque is not supplied. A control signal generator actuates the motor in response to the reception of an access code input by the user.

  • Patent number: 5211040
    Abstract: A combination lock includes a housing, amount upon which is mounted first and second slide members, and a spring plate. The first slide member carries a stop stud that engages a closing lug as the first member shifts under spring bias in a plane from an open to a closed position. The second slide member is coupled with the first member and shifts in a plane substantially parallel with that of the first member. Additionally, the second member contains recesses capable of accommodating a tumbler disc that enables shiftable motion of the second member only when a cam on the tumbler is aligned with grooves in the mount. The tumbler disc connects with toothed structure on a combination setting wheel, and the spring plate contains respective fingers for biasing the setting wheel against the tumbler and for engaging catch recesses on the setting wheel. The spring plate further contains a finger for biasing the locking lug for ejection from the housing.

  • Patent number: 5193369
    Abstract: A latch for retaining together two parts of a piece of luggage has a latch element projecting from one of the parts, a housing mounted on the other part and shaped to receive the latch element, and a latch dog movable in the housing between a retaining position preventing the latch element, when engaged in the housing, from withdrawing from the housing and a freeing position permitting the latch element to withdraw from the housing. At least one operating element in the housing is displaceable in first and second nonparallel directions between an actuated and unactuated positions for, on displacement in the first direction and thereafter in the second direction, displacing the dog into the freeing position and for, on displacement in only one of the directions, leaving the dog in the retaining position. Thus if the operating element is accidentally hit by something the latch will not open.

  • Patent number: 5184887
    Abstract: A lock for an interlock mechanism that prevents the opening of more than one filing cabinet drawer at a time. The interlock mechanism comprises a fixed-length channel having at least one movable block and at least two wedges. When a drawer is opened, one of the wedges is moved, thereby filling the channel and preventing the opening of another drawer. The lock selectively prevents the wedges from moving into the channel when all of the drawers are closed, thereby locking all of the drawers in the filing cabinet in a closed position.

  • Patent number: 5150590
    Abstract: A latch for luggage includes: a housing secured to a base case, a trigger slide slidably held in the housing having a lock core rotatably mounted in the trigger slide provided with a lock bolt operatively biased to be retarded by a limiting block formed in the housing for locking the trigger slide, and a hook latch secured to a cover coverable on the base case for forming a luggage or the like and lockably engageable with a recess portion formed in the trigger slide. The hook latch is normally urged by an ejecting spring formed in the trigger slide so that upon a disengaging of the hook latch from the trigger slide when unlocking the trigger slide, the hook and the luggage cover will be automatically ejected upwardly for a quick opening of a luggage.
