Abstract:
A combination lock includes a lock body, a shaft secured within the lock body, and a plurality of coaxially aligned rotary lock elements rotatable about the shaft. Each rotary lock element includes an inner peripheral hub disposed on the shaft and including a radial bore extending from an outer periphery of the hub to an inner periphery of the hub, and an outer peripheral wheel surrounding the hub. A shaft engaging member a wheel engaging member are disposed in the radial bore, with the wheel engaging member extending partially outward of the outer periphery of the hub for engagement with one of a plurality of inner peripheral pockets in the wheel to rotationally fix the wheel with the hub. When the locking shaft is moved from a normal operating position to a code change position, the shaft engaging member of each dial is partially receivable in a corresponding recess in the locking shaft, and the wheel engaging member is receivable into the radial bore to rotationally disengage the wheel from the corresponding hub.
Abstract:
In one aspect of the present invention, a lock assembly comprises a dial, a lock device, and a spindle having a spindle base and an elongate spindle shaft extending from the spindle base. The spindle shaft comprises a plurality of spindle segments having four sides and separated by a plurality of spaced apart grooves. Each of the spindle segments includes a chamfered leading edge. In another aspect of the present invention, a method of mounting a lock assembly on a mounting surface comprises positioning a dial on a first side of the mounting surface, positioning a lock device on a second side of the mounting surface, determining a distance between the first and second sides, providing a spindle including a plurality of spindle segments having four sides and separated by a plurality of spaced apart grooves, and cutting the spindle at a selected one of the spaced apart grooves.
Abstract:
A combination lock comprises a tubular locking case (3) defining an axis and a free opening at one end; a sliding bolt (12) located coaxially and displaceably in the locking case and extending out of the opening of the locking case and provided with a longitudinal key slot (16) and a number of circumferential grooves (15); a number of code discs (7) located rotatably in the locking cases and each having a central opening (9), through which the sliding bolt is extending, and a dowel (10) extending into the central opening and fitting into the grooves and key slot of the sliding bolt; an actuator (18) located coaxially and rotatably in the locking case and arranged to turn the code discs in succession and extending out of the opening of the locking case with an outer part (20) provided with a dial; and catch pins (11) located on the code discs in such a way that they cooperatively align the dowels I the key slot of the sliding bolt when the actuator is turned successively in relation to a mark on the locking case to ciphers corresponding to a specific code. The combination lock furthermore comprises a bolt (26) extending displaceably through the locking case, and a gear segment (24) functioning between the bolt and the sliding bolt to make the two parts displace themselves simultaneously on activation of the combination lock obtains a simple, inexpensive design that con be mounted quickly, easily and safely in e.g. a door. The combination lock furthermore offers a great security in case of fire than a lock with keys. If a person behind a locked escape door with a key lock operated from both sides with a key has not found or cannot find the key in the hurry, or this key is in a place that is inaccessible due to the fire, this person would be unable to unlock the lock and get out at the consequent danger of dying in the fire.
Abstract:
A secure enclosure (10) for an automated banking machine includes a chest portion (12) and a moveable door (14). The door of the secure enclosure has mounted thereon a locking bolt work mechanism (24) which operates in a secure condition to engage locking bolt engaging apertures (46). The door further includes dead bolt projections (150) which engage apertures (62) when the door is in the closed position. The bolt work mechanism includes a drive cam (122) which is engageable by a member of a lock (126). The drive cam is connected to a pair of idler cams (118, 120) by L-links (134, 136). The idler cams are connected to a locking bolt (102) by S-links (138, 140). Movement of the drive cam enables moving the locking bolt between extended and retracted positions.
Abstract:
A resistant mechanical combination lock and improvements thereto is described herein to include one or more of the following features: an improved combination change/set feature including a tumbler interlocking lever (132, 133) with digitated micro-fingers (135) for interdigitating with digitated micro-fingers (131') on the peripheral edge of a combination tumbler ring (131), the lever (132, 133) and the ring (131) sandwiched between outer gate rings (130a, 130b) to form a tumbler wheel assembly; a key stabilization feature in which an internal boss (126) and a pivot recess (125') together help stabilize the change key (122) when changing the combination of a lock to help prevent "lock out"; an improved duress feature including a duress tumbler wheel assembly (200, 250) (including a duress lever (201, 251)) and an interchangeable microswitch (220, 270); and/or a fence control feature preferably including an overcenter spring (330) and trigger plate (333) for controlling fence contact with the drive cam (308).
Abstract:
A combination locking arrangement includes a locking member, a locking lever connected to the locking member; and at least first and second tumbler discs rotatable about a tumbler disc axis. When each of the tumbler discs is rotated to an unlocking orientation, the locking lever engages aligned recesses in the tumbler discs, such that further rotation of the tumbler discs moves the locking member from the locking position to the releasing position. A dial is rotatable about the tumbler disc axis for selective rotation of the tumbler discs, and includes a drive portion rotationally secured in interlocking engagement with the first tumbler disc in one of a plurality of code selecting orientations. The locking lever includes a disc securing portion positioned to prevent axial disengagement of the first tumbler disc from the dial drive portion when the locking lever is engaged with the aligned recesses in the tumbler discs.
Abstract:
A lock includes a housing, a keypad disposed on the housing, and a latch assembled with the housing. The keypad includes a plurality of button assemblies, each including an axially depressible button member including a camming surface, a lock wheel having a plurality of camming teeth, and a latch releasing feature secured to the lock wheel for rotation therewith. Pressing the button member causes the camming surface to engage one of the plurality of camming teeth, thereby incrementally rotating the lock wheel between a plurality of rotational positions. When the button members of a predetermined one or more of the plurality of button assemblies are depressed a predetermined number of times, the latch releasing features of each of the plurality of button assemblies align with a plurality of blocking features of the latch to permit lateral sliding movement of the latch from a locked condition to an unlocked condition.
Abstract:
There is provided a lock including one or more movable locking members movable between a non-actuated position and an actuated position following actuation of the same in use. An intermediate movable member is arranged with respect to the one or more movable locking members such that the intermediate member is moved from a first position to a second position on movement of said locking members from the non- actuated position to the actuated position. A locking bolt is connected to or associated with the intermediate member. The locking bolt is movable from a locked position to an unlocked position in use on movement of the intermediate member from the first position to the second position. The lock further includes additional locking means arranged to prevent movement, directly or indirectly, of the intermediate movable member from the first position to the second position until one or more pre-determined conditions are met.
