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.

Combination lock with security feature

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.

Security device for firearms

A combination lock having dial-driven sleeves mounted in axial alignment on a shaft is provided with a shift member to move the sleeves axially out of coupling engagement with the dials for changing the combination of the lock. The shift member includes a manual actuating portion extending through an opening in the face plate of the lock, and when the lock is on combination, the shift member can be moved transversely to the axis of the sleeves to effect uncoupling of the sleeves from the dials by a camming action.

Combination locks

A latching device for apertured members, such as the sliders of a double-slider zipper employed as a closure on a luggage case, has a latch pivotally mounted on a body member and an upstanding stud which is adapted to be covered by the latch when in latched position. The latching device employs a latching mechanism which is operated by the movement of the pivoted latch without the necessity of manipulating a secondary, manual actuator, thereby permitting the latching device to be operated with one hand. The device includes a pair of plungers slideably disposed within a housing, the plungers having end portions extending beyond the housing which are shaped for cooperation with cams attached to the underside of the latch. The plungers are driven into the housing by the cams when the latch is lowered or raised. When the latch is open, the plungers are held partially driven into the housing, thereby reducing the downward force necessary to close the latch. A combination lock is included within the device to lock the latch in latched position.

Latching device for apertured members

A latching system particularly for a latching console used on a luggage article to releasably secure a body section of the article to a hinged lid, includes a pivotal latch assembly conveniently incorporated in the handle structure of the luggage article. The latch assembly includes a dial and sleeve type combination lock so that the latch assembly can only be operated when the lock is 'on combination.' The latch assembly is linked to a rod extending lengthwise of the console and having sliding latch members at its opposite ends which cooperate with complementary hasp formations on the respective sections of the luggage article. Pivotal movement of the latch assembly is thereby accompanied by longitudinal movement of the rod to operate the sliding latch members. The hasp formations may be in the form of ribs integrally formed with the respective sections of the luggage article.

Latching systems particularly for articles of luggage

A latching system for a luggage article comprises a pair of spaced swiveling latches mounted on the interior of a front wall of the article, the latches being connected together for swiveling movement in unison between latching and unlatching positions by means of an endless drive cable. The latches are operated by a single manual actuator including a swiveling lever connected to one of the latches by a lost motion connection which allows the lever to be returned to a rest position after moving the latches into their latching or unlatching positions. A combination lock is provided for locking the actuator lever in the rest position except when the lock is on combination.

Latching system for luggage articles

A hardware assembly for luggage and the like includes a latch pivotally supported on a luggage case and held in a closed position by engagement between catch elements on the latch and cooperating catch elements on a control member supported for movement along the case, the control member being biased in a direction to engage the catch elements. A pivoted manual actuator associated with the latch engages the control member and is capable of moving the control member in a direction to disengage the catch elements to allow the latch to be opened, when the manual actuator is operated. The catch elements serve as a safety catch to prevent the latch from being opened until the catch elements are disengaged. The hardware assembly may further include a latching slide member coupled to the latch by a link member for movement with the latch, and for engaging a cooperable latch element on a second part of the case when the latch is in the closed position. A combination lock may also be included for blocking movement of the control member necessary to open the latch.

Hardware assembly for luggage and the like

A dial and sleeve type combination lock is provided with a shift member to move the sleeves out of coupling engagement with the dials for changing the combination of the lock. The shift member includes a manual actuator extending through an opening in the face plate of the lock which opening extends transversely to the axis of the sleeves and movement of the actuator in the opening in the transverse direction effects axial movement of the sleeves by means of an oblique camming surface on the shift member.

A dial and sleeve type combination lock is provided with a shift mechanism for moving the sleeves out of coupling engagement with the dials for changing the combination of the lock. The shift mechanism includes a rotary actuator mounted coaxially with the sleeves and having a portion of its periphery extending through an opening in the face plate of the lock. When the lock is on combination, the actuator can be rotated to move the sleeves out of coupling engagement with the respective dials by a camming action.

A latching device for the sliders of a double-slider zipper arrangement comprises a pair of tab assemblies formed for attachment to the pull tabs of the sliders, and a latch assembly mounted on one of the tab assemblies and formed for latching engagement with the other tab assembly. In the latched position, the latching device securely holds the sliders in substantially abutting relationship. The latch assembly may be sized to cover the sliders. A locking mechanism is also included for locking the latching device in a latched position.

Double-slider zipper latching device

A combination lock of the dial and sleeve type has a scramble feature enabling a hasp to be engaged with a latch of the lock even when the dials and sleeves are not on-combination, by independent movement of the latch relative to manual actuating means of the lock. When the hasp is engaged, it supports the latch in a position in which the latch is adapted to engage a blocking element that prevents the latch from being moved out of its hasp-engaging position independently of the manual actuator. This arrangement effectively prevents the lock from being forced open when the hasp is engaged.

Combination lock with scramble feature

A dial and sleeve type combination lock is provided with a shift member to move the sleeves out of coupling engagement with the dials for changing the combination of the lock. The shift member is operated by depressing a manual actuator portion thereof in an opening in the lock casing and the shift member includes a cam surface which moves the sleeves out of coupling engagement with the dials responsive to depression of the manual actuator portion by reaction of the shift member with an internal surface of the lock casing.

A dial and sleeve type combination lock is provided with a shift member to move the sleeves out of coupling engagement with the dials for changing the combination of the lock. The shift member includes a manual actuator extending through an opening in the face plate of the lock which opening extends obliquely to the axis of the sleeves and movement of the actuator in the opening effects axial movement of the sleeves by a camming action effected against an obliquely extending surface of the opening.

A dial and sleeve type combination lock is provided with a shift member to move the sleeves out of coupling engagement with the dials for changing the combination of the lock. The shift member includes a manual actuator portion extending through an opening in the face plate of the lock. Axial movement of the sleeves out of coupling engagement with the respective dials is effected through a camming action by moving the manual actuator portion in the opening axially in the opposite direction to the direction of movement of the sleeves.

A combination lock having a latch mechanism capable of being closed even when the lock is off combination employs an axially movable shaft rotatably supporting combination dials and having a latch element for engaging a cooperable hasp, the latch element being spring biased to a latched position. A slide member, the movement of which is blocked when any dial is off combination, is coupled to the latch element and the shaft and connected to a manual actuator for moving the latch element to an unlatched position. The coupling permits the latch element to move to its unlatched position independently of the slide member so that the hasp may enter the lock and be engaged by the latch element when movement of the slide member is blocked. The operating mechanism of the lock is supported on a frame by a support member connected to one end of the shaft and by a shift lever slidably related to the shaft at its opposite end.
