  • Patent number: 6058745
    Abstract: A padlock cover assembly for use in latching and locking doors includes a cover with a peripheral wall. The cover is pivotally mounted to a pivot base which is pivotally mounted to a first door member by a pivot pin. The cover is pivotal relative to the pivot base into and out of covering relationship with a padlock supported by its shackle on a padlock mounting bracket secured to the second door member. A pawl is formed on the cover and sized and positioned such that the pawl is advanceable between the shackle and an upper surface of a padlock body when the cover is advanced into covering relationship with the padlock supported on the mounting bracket in an unlocked condition. The cover is then pivotable about the pivot pin such that a portion of the peripheral wall of the cover engages a bottom of the padlock body advancing the padlock body toward the shackle and into a closed condition.

  • Patent number: 5988712
    Abstract: An anti-theft device is constituted by an elongated rod of a width less than the gap between a window glass pane and a facing inner edge of a window sill for an automobile door interior panel. A shield plate is fixed to and extends radially outward to one side of the rod at a distal end, and a wedge is fixed to and extends alongside the rod adjacent the proximate end, with the wedge having a thickness greater than the width of the gap and tapering over its length to a tapered leading edge facing the trailing edge of the shield plate. By inserting the shield plate into the interior of the door within the gap and twisting the rod about the axis, the wedge is forced into frictional locking position between the inside of the window glass pane and the window sill, with the shield plate covering the door mechanism actuating lever.

  • Patent number: 5921115
    Abstract: A device is adapted for use primarily as a theft deterrent for bicycles, mopeds and other two and three wheeled self propelled or motorized conveyances, said device comprises a pair of opposed, telescopically engaging U-shaped members and locking means associated with said members, securing them from being forcibly pulled apart. The locking means typically includes the use of a pawl and ratchet arrangement for facilitating the engagement of the two members for securing them in locking relationship. The device also includes a compressible and extendible rubber or elastomeric boot preferably in the form of bellows. This boot provides a protective cover around ratchet teeth that are longitudinally spaced along one of the arms of the two U-shaped members. The boot progressively surrounds the ratchet teeth as the rod is disengaged or withdrawn from the sleeve.

  • Patent number: 5878604
    Abstract: A plurality of walls form a housing cavity in which a latch hasp is received. An opening in the housing receives therethrough the latch hasp, the latch enclosing the cavity. The bolt seal has a shank with a head at one end or with a U-shaped bight in a second embodiment. The head engages a housing wall and a locking body engages and locks to the shank at a shank end distal the head. The shank between the head and lock body is fully enclosed by the housing and latch to preclude access to the shank by tampering tools. In a second embodiment, the shank bight engages the received hasp of a latch. The shank distal the bight is locked to the housing by a locking body. The latch depends into and encloses the housing cavity open at the top. The shank between the bight and the locking body is fully enclosed in the cavity. Different housings are disclosed wherein the head may be enclosed or exposed for access by a shank breaking tool. A reusable bolt and locking body is disclosed for use with several embodiments.

  • Patent number: 5875659
    Abstract: A padlock weather shield comprising a preformed sheet of weather resistant material for fully covering and protecting a lock from exposure to weather related conditions such as precipitation. The shield is a patterned sheet member which bends or folds to form a box having front, side and rear panels and a curvilinear and convex roof. In one embodiment, the rear of the patterned shield has a slit to fit over a door handle. In a second embodiment, the rear has a pair of tabs and a slit to snap fit over a staple, the hasp securely anchoring the padlock weather shield in place when installed onto the staple. The roof is convex to allow precipitation and moisture to drain off of the top of the shield and down the box, and acts as a living hinge, permitting the box to be raised to access the protected lock.

  • Patent number: 5802896
    Abstract: A safety lock-set is provided which includes a main body, a socket and a bushing. The heat-treated socket is used not only to close off the lock-pin hole of the main body, but also to form a skirt for the spring and the back end of the latch. The heat-treated bushing is provided to sleeve over the connecting area of the set bar and the latch from the lock barrel side. The socket and the bushing connect together with a respective curved notch on each one, to form a closed connecting sleeve to protect the connecting areas of the latch and the spring and the set bar, in order to prevent someone from drilling through the lock-set.

  • Patent number: 4096719
    Abstract: A door-lock is provided with a lock-housing which accommodates a lock mechanism. The lock-housing comprises two connectable parts, of which at least one can be connected to a face plate which is provided with recesses for the dead bolt and latch bolt of the lock. The face plate comprises a U-shaped member which coacts with the end of the lock-housing facing the face plate to stiffen the lock-housing and form a combined unit which presents high resistance to forcing. The face plate and the member form a separate element which is removably connectable to the lock-housing. The lock-housing may either have a recess for receiving the member, said recess engaging around the two lock-housing parts, or, alternatively, the end of the lock-housing facing the face plate may be open; in which case the member enters the lock-housing through said opening and the two lock-housing parts engaging around the member.

  • Patent number: 4041741
    Abstract: Protective plates for protecting against two common methods of breaking and entering an automobile trunk are disclosed. One plate is mounted on the outside of the trunk lid and the other plate is mounted on the inside of the trunk lid. The plate mounted on the outside of the trunk lid protects the trunk lid in the immediate area of the trunk lock. The plate mounted on the inside of the trunk lid protects against forceable removal of the lock cylinder. The plate that is mounted on the outside of the trunk lid surrounds the trunk lock and has a central opening to permit access to the trunk lock. Two threaded studs secured to this outside plate pass through holes drilled in the trunk lid and through holes provided in the plate that is mounted on the inside of the trunk lid. The plate mounted on the inside of the trunk lid has a central opening and is slipped over the trunk lock cylinder and over the two studs of the outside mounted plate.
