  • Patent number: 8973415
    Abstract: In one example, a padlock storage system includes a central portion including a padlock body having a shackle and a key for opening the padlock body. The system includes an upper end having a chamber for accommodating the shackle and a lower end having a chamber for placement of a key. Additionally, a coupling system between the central portion and the lower end allows for rotation of the lower end in relation to the central portion and promotes the unlocking of the shackle, where the key activates the unlocking. The padlock system is operable in two operating positions, where the upper and lower ends are able to attach to each other by removal of the central portion or where the central portion is attached to both ends. When the central portion is removed, a retention capsule for containing the key is formed, and which can be held in an apparatus.

  • Patent number: 8806905
    Abstract: A padlock includes a lock body, a shackle assembled with the lock body, a lock subassembly disposed in a cavity in the lock body, and a shackle retainer assembled with the lock body. The lock subassembly is operable between a locked position securing the shackle in a closed position and an unlocked position permitting movement of the shackle to an open position. The shackle retainer extends into a first shackle bore and is received in a recess in a first leg of the shackle. When the shackle is in the open position, the lock subassembly is manipulable to be moved from a first position to a second position to generate a space in the cavity aligned with the shackle retainer, such that the shackle retainer is extendable into the space for disengagement of the shackle retainer from the first shackle leg recess.

  • Patent number: 5715709
    Abstract: By forming a plurality of false void zones in a lock housing in association with the tumbler release channel, a combination lock construction is attained which virtually eliminates the ability of trained individuals to gain unwanted access to the lock. Preferably, the combination lock housing also incorporates a plurality of non-releasing open or void zones or slots formed in association with the lock release groove for each rotatable tumbler sleeve. In this way, the desired false click is provided for each rotatable dial in order to thwart unwanted opening of the combination lock of this invention. Furthermore, the lock construction of the present invention is constructed with the interior chambers thereof virtually sealed from ambient surroundings, thereby preventing unwanted contamination from entering the interior of the lock and the rotating components thereof. In this way, degradation by contamination is virtually eliminated.

  • Patent number: 5706679
    Abstract: A harness for securing more than one part of a vehicle to a station comprising a tether and a U-lock. The U-lock includes a tubular body and a solid shackle. The body has a pair of aligned holes in the wall and a locking mechanism. The shackle is a U-shaped, solid rod, where one leg has a bent foot that fits into one aligned hole and the other leg has a shaped foot adapted to be captured by the locking mechanism after being inserted into the other aligned hole. The tether includes a length of flexible material and a cuff. The length is a braided cable or a chain, and is sheathed. A hardened steel cuff is rotatably connected to the one end of the length. The cuff has a number of configurations of openings through which components of the U-lock are inserted before the U-lock is assembled. A loop is connected to the other end of the length and is sized to permit the cuff, but not the U-lock, to pass through.

  • Patent number: 5622066
    Abstract: An improvement in a bicycle lock extends the ability of an existing bicycle lock of the type having a U-shaped shackle to secure a bicycle to a post, against theft, by slipping a generally U-shaped essentially rigid link over a leg of the U-shaped shackle of the existing bicycle lock, subsequent to locating the rear wheel of the bicycle in the link, so that upon locking the bicycle frame and front wheel of the bicycle to the post with the U-shaped shackle, the existing bicycle lock also secures the rear wheel of the bicycle against theft.

  • Patent number: 5174136
    Abstract: A padlock with removable cylinder mechanism offers the user a choice of two distinct manners of operation or "functions"--a Key Retaining function and a Non-Key Retaining function. This dual function capability in a single unit is achieved by a rotator bolt bored to allow placement of a pattern of pins. A series of pins, which when installed in the rotator bolt in a specified pattern, causes the function selection to be accomplished. A re-keyable padlock which accepts widely available, standard dimensioned, generic key operated lock cylinders allowing the keying of this padlock to be adapted to the wide range of keying systems used in locks found in residential, commercial and other uses as required for security and convenience. The use of standard dimensioned cylinders in the padlock is accomplished by a cylinder retainer, tailpiece stop and rotator bolt which adapts the generic cylinder to padlock use.

  • Patent number: RE38832
    Abstract: A dual-function lock in accordance with the invention has an axis-defining lock sub-assembly including first and second axially aligned rotator members having confronting first end faces and oppositely facing second end faces. The sub-assembly has a lost-motion recess and an anchor recess on one confronting face and one recess-engaging member extending from another confronting face to permit lock function selection by placing the recess-engaging member into a particular recess. Alternative dual-function lock sub-assemblies include a unitary rotator bolt and a companion actuator. The rotator bolt has a release-mechanism-engaging portion and an actuator-engaging portion. While a first section of the actuator-engaging portion permits limited lost-motion between the rotator bolt and a companion actuator, a second section prevents lost-motion. The lock function can be selectively determined by placing the companion actuator into the desired first or second section of the actuator-engaging portion.
