Abstract: A combination lock has a pivoting bolt for engaging and disengaging a hasp. The hasp, which is disengaged from the bolt when the lock is on-combination, may be re-engaged with the bolt, even if the lock is off-combination. A first spring resiliently biases the bolt to an unlocked position. A second spring resiliently restrains movement of the bolt beyond a locked position in order to prevent disengagement of the hasp in response to application of a shock force to the lock.

Abstract: A double zipper lock for a luggage case comprises a base with a housing containing a combination lock, and a U-shaped loop adapted to embrace the housing. Arms of the loop are pivotally mounted on opposite ends of the housing and a bight portion of the loop cooperates with portions of the base to form chambers that, when closed, trap zipper sliders. When the combination lock is set on-combination, the user may lift the loop, to free the sliders, by engaging the bight portion with the fingers of a hand and using the thumb to press a manual actuator inwardly of the housing. The actuator is part of a bolt that is supported for pivotal and translational movement. The translational movement, which is permitted only when the lock is on-combination, causes pivotal movement of a latch member from a latching position to an unlatching position. In the latching position, the latch member prevents lifting of the loop.

Abstract: Front-programmable combination lock in which a shift member moves with a manual actuator button between locked and unlocked positions of the button and also has shifting movement relative to the button to permit the unlocking combination of the lock to be changed. Access to the shift member is provided by openings at opposite sides of the manual actuator button.

Abstract: A combination lock has a faceplate movable from a first position to a second position only when combination dials are set to an opening combination of the lock, the dials being movable with the faceplate portion from the first position to the second position and being rotatable relative to the faceplate. A spring biases the faceplate portion toward the first position. A manually shiftable member, also movable with the faceplate from the first position to the second position, is shiftable relative to the faceplate to hold the faceplate in the second position and, at the same time, to permit the dials to select a new opening combination of the lock. The faceplate constitutes a manual actuator that controls a latch.

Abstract: Dead bolt combination lock having an inexpensive lock mechanism, of a type known in the luggage industry, that cooperates with a one-piece bolt. The bolt is supported for reciprocative movement on internal shoulders of a housing and forms a detent device with a resilient arm of a back cover of the housing, so that the bolt is releasably held in its locked and unlocked positions. The bolt is locked in one of those positions when the combination lock is off-combination. The configuration of the bolt resists bending, and a projecting portion of the bolt contains a case-hardened pin that can rotate to resist sawing through the bolt.

Abstract: A closure, which may be part of a glove compartment drawer of an automobile, is controlled by a latch pivotally supported on a base that also supports a combination lock. When the lock is set to its unlocking combination, the latch is permitted to move from a latched position and is moved toward its unlatched position by cooperable camming formations on the latch and the closure.

Abstract: A bistable electromagnetic latch, particularly adapted for use with an electronic combination lock on a luggage case, comprises a magnetic member pivotally mounted for rotation between a pair of pole pieces, the magnetic member having first and second stable rotational positions at which each magnetic pole is adjacent to a different pole piece, and a pair of oppositely wound coils associated with the pole pieces and responsive to the momentary flow of electrical current therethrough for producing a magnetic flux that causes the magnetic member to rotate from one position to the other.

Abstract: A multi-dial combination lock is provided with a security feature whereby the dials are rotated when the lock is opened in order to upset the on-combination setting of the dials. Each dial has a heart-shaped cam and a cam operator is provided including followers for the respective cams. When the lock is set on-combination, and an actuator is moved manually in order to open the lock, the actuator also works the cam operator so as to apply pressure to the cam formations on the respective dials effective to rotate each of the dials into a set orientation. In the set orientation to which the dials are rotated, each dial may be orientated so as to display the same combination indicium, e.g. "0". The lock also includes a shift member for changing the set combination of the dials, the shift member being situated in a pocket formed in the manual actuator.

Abstract: A security device for a firearm comprises a pair of covers adapted to be disposed on opposite sides of a firearm trigger guard. One of the covers has an elongate protruding housing containing the latching portion of a latch member and the other cover is formed with an opening in which is disposed a catch member adapted to engage and retain the latching portion when the covers are pressed together with the trigger guard therebetween and with the housing being projected through the trigger guard into the opening. The covers when mutually engaged embrace the trigger guard and prevent operation of the trigger. The latch member may be moved out of engagement with the catch member to release the covers by means of a manual actuator which is controlled by a combination lock contained in the cover which is provided with the latch member. The device may be applied to a range of different firearms.

Abstract: An electronic combination lock for luggage and the like comprises a microcomputer, a display having a plurality of display locations, and a plurality of push buttons, one being associated with each display location. Each push button advances its associated display location through a sequence of digits and enables selection of a desired digit for display. A displayed set of digits is compared with a stored predetermined set of digits, and a bistable electromagnetic latch is operated to open the lock when the sets of digits match.

Abstract: Combination locks employ dial-driven rotary elements for controlling the position of a locking member between locking and unlocking positions by peripheral cooperating of the respective elements with the locking member. Each rotary element is formed in a manner whereby no audible sound or difference in feel is produced during rotation of the element when the on-combination setting of the element is reached. This reduces the possibility that the lock may be picked.

Abstract: A combination padlock has dial-driven rotary sleeves mounted within the lock casing on a longer leg of the padlock shackle. The sleeves have peripheral teeth with at least one tooth being omitted on each sleeve to define a bypass gap. To open the lock, the dials must be rotated so as to turn each of the bypass gaps into alignment with a respective blocking projection in the lock casing. To thwart any attempt to pick the lock, alternate teeth on each sleeve are shorter than the adjacent teeth whereby a detent-type feel may be produced when the sleeve is rotated, simulating the feel produced when the bypass gap is brought into line with the respective blocking projection.
