  • Patent number: 9284753
    Abstract: A method of protecting a lock on the latch of a shipping container or trailer door without modifying the door latch includes a ring having a bar that is connected at both ends to the inside of the ring. The bar has an aperture dimensioned similarly to the bore on the retainer and handle elements of the door latch. The ring has a rim on one side including a saddle at each end of the bar so that when the rim is placed over the latch the saddles straddle the handle and the bores on the bar, the handle and the retainer are aligned. A shackle of a lock is placed through the bores on the handle, bar and retainer. The ring prevents cutting tools from directly accessing the shackle thereby protecting the lock.

  • Publication number: 20090078010
    Abstract: A break-in resistant cylinder for locks, comprising a stator provided with a substantially cylindrical longitudinal cavity for accommodating a rotor with a longitudinal recess for the insertion of a key. The rotor and the stator comprise a plurality of channels which are substantially aligned and face each other (when the cylinder is in the closed configuration); the channels accommodate respective coding pins, tumbler pins and any elastic elements designed to prevent the rotation of the rotor within the stator if the key is not present in the longitudinal recess. At least one of the tumbler pins comprises a bush and a spike; the stem of the spike has a smaller diameter than the inside diameter of the bush and is longer than the bush. The spike is arranged so that its head is directed toward the bottom of the channel of the stator and rests against the elastic elements and the free end of the stem rests against the lower surface of the coding pin.

  • Patent number: 7444846
    Abstract: A drill resistant lock cylinder is useful for resisting attempts to defeat the cylinder using locks or picks. The cylinder includes a cylinder housing (105) having a central axis. Two pinion cylinders (115, 125) are positioned inside the cylinder housing (105) along the central axis. A combination pin cylinder (120) is positioned along the central axis between the two pinion cylinders (115, 125), and the combination pin cylinder (120) and each pinion cylinder (115, 125) includes axial pinholes (220) there through. Pins (130) located inside the axial pinholes (220) in the combination pin cylinder (120) and the pinion cylinders (115, 125) establish two shear lines along axial ends of the pinion cylinders (115, 125).

  • Patent number: 7441696
    Abstract: A locking mechanism for a theft resistant mailbox includes a door assembly. A door is affixed to a frame by at least one pivot point. A cam includes a lever rotatably engaged to a fixed surface at a mounting point and defines a cutout oriented to be removably engaged to a striker attached to a separate surface abutting the fixed surface to form a lock for the door upon urging of the cam along an angle of rotation defined about the mounting point. An anti-pry plate is attached to the fixed surface and juxtapositioned about the cam throughout the angle of rotation by which the lock is effected. The fixed surface includes one of the frame and the door. The separate surface includes an other one of the frame and the door. The fixed surface and the separate surface are provided independent of the at least one pivot point.

  • Patent number: 7441427
    Abstract: A latch has a bushing which has at least one bushing projection or means for preventing insertion of an unauthorized tool to rotate a latch actuator of the latch. Only a key having an outer key recess which can mate with bushing projection on the bushing permits insertion of the key. The cap subassembly of the latch is provided with projections which are of a size and so positioned as to correspond with the internal recesses of the key so as to allow the cap subassembly to enter into the bore of the key and permit a mating engagement of internal recesses on the key and projections on the cap subassembly. Because cap portion rotates freely on top of the cap subassembly which is the part of the cap driven by the key, the arrangement makes it impossible, or at least very difficult, to rotate the shaft and in turn the pawl by means of a tool which rotates the cap portion.
