  • Patent number: 7140209
    Abstract: By providing two separate and independent locking systems formed in a single padlock, with both locking systems independently enabling the single shackle to be released and/or lockingly engaged, an effective, easily produced, multi-purpose padlock is achieved. In the preferred embodiment, a single housing and shackle assembly are employed and constructed for enabling the shackle to be released from locked engagement with the housing using either a rotatable dial combination construction or a key activating tumbler construction. In this way, a dual locking and releasing padlock is achieved which virtually eliminates the difficulties typically encountered with known, prior art lock configurations.

  • Patent number: 6021653
    Abstract: The opening of a sliding shackle permits removal of a stack of individual dial type tumbler rings each may possess a number of individual peripherally disposed indicia plates which are removable from each tumbler ring so removed from the body of the padlock. Each tumbler is keyed to permit opening of the lugged shackle in only one rotational orientation of each tumbler. The indicia plates may be interchanged either with others already on that tumbler, another tumbler, or with other indicia plates altogether. Alphabetic as opposed to numeric indicia are suggested, either fixed directly to the tumbler rings or upon separate indicia plates, of which a large supply may be provided together with the padlock so that a large number of letter combinations are available for the padlock opening combination code which may be set by the owner to a desired code word.

  • Patent number: 4959978
    Abstract: A combination lock or padlock having pushbuttons where the combination of buttons to be pushed to open the lock is mechanically programmable by the user is disclosed. The lock has a case and a locking arm and associated slider, moveable between a locked and unlocked position. A plurality of buttons project from at least one side of the case, and are owner-reversible between two orientations and moveable through holes in the case between first and second positions. In one orientation, movement of the locking means is barred in the first position and permitted in the second position, and in the other orientation movement is permitted in the first position and barred in the second position. The orientation of any button is not being visually ascertainable from outside the case, so the lock owner can program the combination of the lock by selecting the orientation of the respective buttons.

  • Patent number: 4541259
    Abstract: An easily assembled combination lock has improved tumbler wheel construction, combination changing apparatus, and a bi-positional lock cover which selects between spring-bolt and dead-bolt operation. The improved tumbler wheels have two-piece construction, an inner drive member having a projection, groove and stop assembly cooperating with adjacent tumbler wheels, and a gate ring having a gate and improved gripping apparatus for frictionally engaging the gate ring with the inner drive member. The inner drive member has multiple ratchet teeth about its periphery and the improved gripping apparatus includes a pair of diametrically opposed gripping straps integral with the gate ring, in tension, and tangentially contacting the periphery of the inner drive member imparting a predetermined frictional resistance to rotation. Two normal modes of tumbler wheel operation are contemplated.

  • Patent number: 4457147
    Abstract: A combination lock has an array of combination elements that are each movable between first and second positions. Each element 25 has to be in a preselected one of the two positions for the lock to open, and the combination is entered by either moving or not moving each element from an intial or reset position. Then a reader 30 adjacent the elements 25 is simultaneously moved against all the elements to test their positions. Any element not in the proper position blocks the reader from movement; but if all the elements are in their preselected positions, they allow the reader to move and the lock to open. Combination elements 25 are preferably arranged concentrically around a spindle 15 having an external knob 16 that can rotate and move the spindle axially. Each of the elements 25 is preferably a slidable plate with an eccentric notch 26 that confronts and overlaps with a radial notch in reader 30.

  • Patent number: 4395892
    Abstract: A hardware assembly, which is readily adaptable to luggage cases of widely varying constructions, dimensions and configurations, includes a housing which may be positioned within cut-outs in adjacent edges of the side walls of the luggage case, and be mounted on the exterior of one side wall. The housing contains slideable latches for engaging associated hasps mounted on the exterior of the other side wall, and a flexible member connecting the latches to a slideable actuator mounted on the housing for opening the case. The coupling between the latches and the flexible member allows the latches to move to unlatching position independently of the actuator to facilitate closing and latching of the case when the parts are brought together. The actuator is U-shaped and supported for transverse movement on the housing by a rocker located within the housing.

  • Patent number: 4142388
    Abstract: The tumbler includes a connection between an outer gate ring and an inner drive member of a tumbler wheel together. The gate ring includes a leg on the gate ring with a gripping portion thereon. The leg normally biases the gripping portion to a securing position against the drive member to grip it so that the gate ring and drive member normally rotate together. An opening is provided in the gate ring adjacent the leg having a curved portion about its periphery for receiving a key having a curved portion about its periphery. The key rotates against the curved surface of the opening, and a cam section of the key cams a cam follower portion of the leg when the key is rotated to a releasing position for urging the gripping portion away from the drive member. The camming surface, opening and cam follower are so provided that on rotation of the key in the opening to the releasing position, the biasing effect of the leg is prevented from tending to return the key to the securing position.
