Abstract:
A rekeyable lock includes a lock casing formed with a lock cylinder hole, a pin replacing hole and a plurality of first pin holes; a lock cylinder rotatably arranged in the lock cylinder hole and formed with a plurality of second pin holes; a pin set including a plurality of first pins respectively accommodated in the first pin holes, and a plurality of second pins respectively accommodated in the second pin holes; and a pin cover arranged in the pin replacing hole and including a cover body formed with a groove, and a sliding block arranged in the groove and slidable relative to the cover body. When the sliding block is located at a predetermined position, the sliding block and the cover body are configured to respectively abut against an inner wall of the lock casing to fix the pin cover in the pin replacing hole.
Abstract:
The present invention relates to a lock and a key for the same, and multiple modular lock core units are mounted in the lock. Multiple lock bead units having specific standard are mounted in each lock core unit. Each lock bead unit is detachable and is able to rearrange the permutations of the lock bead units. The key includes a handle, a core bar and multiple unlocking blocks. The core bar is connected with the handle. The unlocking blocks are detachable, are mounted around the core bar and have multiple lock teeth sequentially formed around the inner peripheries of the unlocking blocks. A user can adjust the permutations of the key teeth of the key to unlock the lock that has different permutations of the lock bead units, also can change the permutations of the lock core units to get the same effects.
Abstract:
A locking cartridge including a housing, first and second plates rotatably mounted in the housing, a blocking member, and a movable member. The cartridge also includes a cam interface which urges the first plate toward the second plate when the plates are rotated. The blocking member is configured to move among a blocking position and an unblocking position in response to engagement with a first cut on a key. When in the blocking position, the blocking member blocks the first plate from moving toward the second plate. With the second plate blocked from moving toward the first plate, the cam interface prevents rotation of the first plate. The movable member is configured to move among a first position and a second position in response to engagement with a second cut on the key. In certain embodiments, the movable member may be a control pin or a second blocking member.
Abstract:
A method of manufacturing a lock assembly for enabling use of a key-in-knob lock cylinder assembly in different types of lock assemblies. The method includes providing a key-in-knob lock assembly having a key-in-knob housing and a plug rotatably engaged within the key-in-knob housing, providing an interchangeable core lock assembly having an interchangeable core housing, and inserting the key-in-knob housing into the interchangeable core housing such that the key-in-knob housing is universally exchangeable between the key-in-knob lock assembly and the interchangeable core lock assembly.
Abstract:
A lock mechanism includes a cover plate positionable over a plurality of pin chambers in a cylinder housing wherein one or more of the pin chambers include an internal threaded portion. The lock mechanism includes one or more pin assembly caps that are operative to secure the cover plate to the cylinder housing of the lock by threadably engaging with threaded pin chambers. The pin assembly caps include an internal cavity sized to receive at least a portion of a pin assembly, such that threaded pin chambers and unthreaded pin chambers have substantially the same dimensions without substantially increasing the dimensions required for the lock mechanism. The pin assembly caps include a socket (e.g., a hex socket, a Phillips-type socket, or the like) that allow users to selectively remove and secure the cover plate to the cylinder housing common tools.
Abstract:
The present invention concerns a pin tumbler lock system having a housing, a plug, and easy accessible driver pins, key pins and springs. The system is configured so that the lengths of the key pins are adjustable from the outside without taking the lock apart.
Abstract:
A pin tumbler lock having a housing with a series of holes running parallel to the longitudinal axis of the cylindrical bore in the housing. The holes are bored through the housing, and a first end of each hole opens to one of each of the chambers in the housing, between the first and second ends of the corresponding chamber, and a second end of each hole opens to the outside of said housing. A tool having a body comprising a tumbler-lock-housing receiving cavity, for receiving the housing therein, wherein the body comprises a first and second series of channels for creating the holes in a conventional pin tumbler lock housing.
Abstract:
The locking cylinder has a basic code which can be changed using at least one change key (17, 17′). A rotor (3) is mounted in a cylinder housing (2a, 2b) and has a keyway (4) into which a shank of a standard key which is provided with control surfaces 18 can be pushed in order to position the tumblers which are arranged in three first rows (A, B, C). Further tumblers have coding elements (13) which are arranged in further bores in the cylinder housing (2a, 2b) in a programming position of the rotor (3). The change key (17, 17′) interacts with three further rows (D, E, F) of tumblers in the programming position, these tumblers being arranged in slides. These further rows (D, E, F) each contain tumblers having coding elements (C). The locking cylinder can be produced with a smaller outside diameter and be installed in a particularly cost-effective manner.
Abstract:
A rekeyable lock cylinder comprising: a cylinder body having a longitudinal axis and defining a longitudinally spaced, radially-aligned first plurality of pin chambers, each of said first plurality of pin chambers adapted to house a corresponding first pin, said cylinder body further defining a longitudinally extending slot therethrough; and a plug assembly disposed in said cylinder body, said plug assembly comprising a plug body defining a second plurality of pin chambers, each of said second plurality of pin chambers adapted to house a corresponding second pin, said plug body rotatable within said cylinder body between a first position and a second position, said first position aligning said second plurality of pin chambers with said first plurality of pin chambers, said second plurality of pins removable from said second plurality of pin chambers when said plug body is in said second position.
Abstract:
A cylinder lock comprises two barrels in axial alignment on either side of a web. Each barrel is formed as two opposed elements disposed in either side of a longitudinal plane in which the keyhole is formed by confronting surfaces of the opposed elements. The web is engageable with internal end parts of the barrel elements and each barrel comprises tumblers received in the barrel and operable by a key inserted in the keyhole. A one-piece lock block has a central recess through which the web passes and two rectangular parts on either side of the recess each having a narrow top surface contiguous with one of the barrels. Pins are received in bores in the lock block and the pins are spring-biased to lock the barrels when the key is absent. Two housing members each engage over one of the rectangular parts and the corresponding barrel to maintain the barrels in contact with these parts.
