Protectors Patents (Class 70/54)
  • Patent number: 6367292
    Abstract: A protective device for locking two relatively movable objects of a cargo container in a fixed relationship comprises a housing having an open end and a flange extending about the periphery of the open end. The housing is mounted on one of said objects. A longitudinally movable bar is mounted on the interior of housing and extends therethrough for cooperatively engaging a sleeve mounted on the other of the objects for locking the objects together. A collar is also mounted within the housing for enclosing the bar. The collar has a padlock retainer formed between its ends for providing a recess which exposes a hole in the bar when the bar is in cooperative engagement with the sleeve. The recess forms an opening for receiving the shackle of a padlock while the hole is adapted to allow the shackle of the padlock to extend through the bar when the bar engages the sleeve.

  • Patent number: 6357266
    Abstract: A latch cover is secured over a latch to be protected by the lock which locks the latch, and the latch cover restricts access to the latch to reduce the chance of tampering with the latch. The latch cover includes a cover plate sized to cover a substantial portion of the latch and lock when held in a position in front of the latch. Holding plates extend from the cover plate over the sides of the latch where a lock member of a lock locking the latch extend. Such lock member extends from the opposite sides of the latch and through holes in the holding plates to secure the cover in place. Side plates preferably extend between the holding plates to form a box structure to more fully cover the latch. Notches in the side plates receive items extending into or from the latch and help position the cover. The cover allows access to the lock so the lock and latch can be opened when desired and the cover removed.

  • 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: 5865043
    Abstract: A padlock concept consisting of a novel shackle comprised of two tapered shackle elements arranged so that they overlay each other to enclose and opening sufficient to accept the sample of a hasp or attachment device. The shackle elements are connected at one end and when unlocked and unlatched are free to move apart, in a motion causing the two shackle elements to separate, providing a clearance between them, at the unconnected end. Each shackle element includes an opening to allow the staple of the hasp to pass to the common opening. This clearance occurs in opposing elements so that when the elements are brought together or closed the staple of the hasp is completely enclosed by the two shackle elements which substantially fill the space available within the hasp staple. The elements are then latched and locked to provide the security function of a padlock engaged with the staple of a hasp or attachment device.

  • Patent number: 4843845
    Abstract: A protector for use with a conventional padlock having a lock body and a shackle of inverted U-shape characterized by a pair of legs shiftable inwardly of the lock body when the padlock is locked, and shiftable outwardly when the padlock is unlocked. With the shackle fitted to a conventional hasp staple, the protector can be placed in protective position over the staple and the unlocked shackle. Moving the protector in a predetermined direction locks the protector to the shackle legs so that the protector cannot be moved outwardly and removed. When the padlock is locked the lock body moves partially into the protector so that the protector cannot be moved oppositely of the predetermined direction for removal until the padlock is unlocked.

  • Patent number: 4835996
    Abstract: A lateral extension of a shackle end and a lock body securely engage a hasp therebetween. Broadening the shackle end or tapering the shackle provides lateral extension. A shroud or encasement around the hasp, shackle and lock body provides additional security. A sliding shroud with attached shackle fits over the lock body encasement. Alternately, an extension of the lock body encasement itself serves as a shroud with a removable shackle, or a swing plate covers the hasp. Pivoting or rotating arms may secure the shackle to the lock body. Close contact with the hasp and encasement protects against tampering.
