Abstract:
The invention concerns a mechanism for authorising a control member movement by forming a code, comprising a body (20), several stop elements (24) each arranged in a hole of the body (20), an elongated slide (28) sliding in a sliding space and having a series of cuts along each of its lateral edges, push-buttons (14) for moving a corresponding stop element and bearing different signs displayed outside the mechanism such that the sequential control corresponds to a series of signs forming a code, a return tilting plate, and a linking device for transforming a control member movement into a movement translating the slide (28). The invention is applicable to locks.
Abstract:
This invention relates to sequential locking apparatus used to lock, for example a door which has an actuating handle and an associated bolt opening mechanism. The apparatus has a lock release arm, a pin and barrel associated with the lock release arm and acode entry mechanism which collectively control whether the lock can be unlocked by a user. The code entry mechanism comprises a rotatable shaft, an obstruction portion provided on the rotatable shaft for selective engagement with a portion of the lock release arm and a series of clutch mechanisms provided on the rotatable shaft. Each clutch mechanism has drive and driven components and an actuation portion communicable with an associated entry button such that pressing the associated entry button selectively results in rotation of the rotatable shaft to cause actuation of the lock release arm. This arrangement only allows the locking apparatus to be unlocked when the entry code is entered in sequence.
Abstract:
A combination locking assembly (31) having a simplified and robust construction is provided with easily positionable slide members (161) for setting the combination. Combination bars (141), and increment bar (143), and an advance bar (145) cooperate to prevent a locking bar (123) form being moved to an unlocked position unless the correct push buttons (39) are sequentially depressed in the correct order. As the correct push buttons (39) are sequentially depressed, the combination bars (141) are caused to individually advance to a translated position. A common panel (189) is provided which cooperates with notches (187, 188) in the combination bars (141) to hold the combination bars (141) in their advanced positions until the last push button (39) in the correct combination sequence is depressed, thereby causing the locking bar (123) to move to its unlocked position.
Abstract:
A door lock includes a latch assembly positioned at least partially within the door and movable between an engaged position in which the door is held in a closed position and a disengaged position in which the door is movable from a closed position to an open position. An outside spindle is rotatable about an axis and an inside spindle is rotatable about the axis to move the latch assembly between the engaged position and the disengaged position. A locking plate is movable along the axis between a locked position in which the outside spindle is fixed and an unlocked position in which the outside spindle and the inside spindle are each rotatable and a privacy lock actuator positioned on the inside of the door and movable in a direction substantially normal to the axis to move the locking plate between the locked position and the unlocked position.
Abstract:
The present application includes a combination lock system having gears, cams, and an interference system. In one embodiment, The angular position of the cams is adjusted by a user interface through operation of the gears. When the cams are in a predetermined position, the interference system is movable with respect to the cams and the system is unlocked. The user interface may be a pushbutton keypad.
Abstract:
A lock (10) comprises a housing (11 ) defining a mounting face (12), a locking mechanism (21 ) accommodated in the housing (11 ) and operable to change between a locking state and a release state and a set of operating elements (25) with buttons (26) accessible at the front of the housing and actuable, such as by axial displacement, to operate the locking mechanism (21). The locking mechanism (21 ) can be changed from the locking state to the release state in response to actuation of, and only of, a selected group of the operating elements (25). These elements can additionally be manipulated, in particular rotated, to select the group. The buttons of the selected group can be identified by respectively associated digits forming a code. The lock further comprises a slidable blocking plate (31) blocking the rotation of the operating elements (25) and cancelling means (36 - 38) operable to cancel the blocking by the plate (31). The cancelling means includes a key barrel (37) accessible for operation externally of the housing (11) at a place, in particular the front of the housing, separate from the mounting face. Operation of the key barrel (37) thus has the consequence of freeing the buttons (26) for rotation to change the code.
Abstract:
A mechanical puzzle lock core includes a code set (31). A rotor core (21) and a rotor gear (12) are mounted in the code set (31), a tooth unlocking the lock and a hole fixing an encode tooth are provided on the rotor core(21), the encode tooth(14) is mounted in the hole corresponding to preset encode. There is a rotor gear coiled spring(13) between the rotor gear(12) and the code set(31). Rotor gear tab(35) of a identifying frame (27) is provided in a groove of the rotor gear(12),a identifying slice(23) is jointed on the identifying frame(27). The rotor core (21) is fixed to a rotor concentric axel(20), and the rotor gear(12) is mounted on the rotor concentric axel(20). There are a encode tooth pusher (36) and an identifying slice pusher (37) on the bottom of the key pusher plate (1). The unlocking machine is connected with an unlocking gear. The mechanical puzzle lock cylinder has a large number of password and strong security and reliable action.
Abstract:
The invention relates to the lock for closing of hand luggages as bags, suitcases etc. The lock consists of a bath (1) fixed in a body of luggage. The bath (1) is equipped by a side hole (4) for a latch (5) of the buckle (2) and by socket on the opposite side (17). The buckle (2) consists of at least three keys (6) equipped by pins (7) movably located at the basic desk (8) and under them there is a movable code desk (9), equipped by operating edges (19) on its upper side and finished by latch (5) and under that a bottom desk (11) located on the first elastic element (12) on the bottom of bath (1) joint with a basic desk (8) by a joint element (18) inserted into the socket (17) of the bath (1). One operating edge (19) of the code desk (9) is always situated against bevelling of one of pins (7) and the rest of operating edges (19) is gradually, according the order of pins N determined by the code, moved towards the corresponding pins (7) to the latch N-1 times of the distance (a), which is shorter than a diameter of the pins (7). The code desk (9) is, on the opposite side than where the latch is, equipped by second elastic element (13). The code desk (9) is on its upper surface equipped by transversal grooves (14) or point holes.
