  • Patent number: 10612279
    Abstract: A lock device for holding an openable and closable member in a closed state. The lock device includes a base member, an operation member, a rod, and a cylinder lock. The cylinder lock has a protruding portion biased to protrude radially outwards to be engaged with an engaging portion formed on a rear side of a cylinder accommodating portion. The rod has a distal end portion configured to move out of a through hole formed in the openable and closable member to be engaged with a locking portion on a fixed member over a predetermined length with the openable and closable member left in a locked state, and a pushing portion enables a release of an engagement with the engaging portion when the rod moves in a receding direction to abut with the protruding portion, causing the protruding portion to recede against a biasing force.

  • Patent number: 9920549
    Abstract: Some designs of combination padlock allow users of the padlocks to set the combinations that unlock the padlocks. However, the operations which a user must perform to set the combination of a padlock typically involve manipulating the shank of the padlock by pulling the shank away from the housing of the padlock or pushing part of the shank further into the housing of the padlock, rotating the shank through a certain angle, and holding or fixing the shank in this position while rotating dials of the padlock to change the combination. Such operations are fiddly, and it can be difficult to remember what steps are required to change the combination. Thus there is provided a combination padlock which goes some way towards overcoming or at least ameliorating one or more of the above problems.

  • Publication number: 20010017049
    Abstract: A lock has a tumbler with a camming surface, the tumbler being urged outwardly when the key is inserted. As the lock barrel moves inwards, the tumbler rotates about an axis against a spring force to pass a formation on the lock housing and, once past the formation, latches behind the formation to prevent the barrel from moving back outwards.

  • Patent number: 5782119
    Abstract: A spring-biased detent to provide selective securement of a door knob assembly to a spindle of a lock mechanism. The detent is inserted transversely in the spindle and biased by a spring clip. The detent may be depressed within the spindle allowing the door knob assembly to slide onto the spindle and subsequently is biased into an aperture of the knob to lockingly attach the knob assembly to the spindle. The detent includes a central aperture for receiving a tailpiece of the lock mechanism. The aperture is configured to allow depression of the detent only when the tailpiece is oriented in an unlocked position preventing removal of the door knob assembly when the latch is locked.

  • Patent number: 5752400
    Abstract: A universal lock and key assembly in which the lock is re-keyable and the key is also changeable. The key has an elongated left side member, an elongated right side member, and an elongated central member. A plurality of key teeth are captured between the shank portions of the left and right side members. The key teeth are interchangeable so that any desired sequence can be arranged to give a predetermined profile to the key. The universal lock has a combination top pin housing and tubular sleeve assembly having a top pin housing and a tubular sleeve portion. A bottom pin cylinder is removably received in the tubular sleeve portion and its bottom pins can be removed and replaced in an order that mates with the key teeth of the key assembly. The structure of the system allows an individual to change both the configuration of the key and also the mating structure within the lock so that it will be operable.

  • Patent number: 5701773
    Abstract: Apparatus for opening, or removing without damage, automotive side-bar type ignition locks, comprises a combination tool with a plurality of projections extending horizontally and forwardly from the combination tool to engage the lock's keyway, at least one balanced pair of recesses in the lock's face, or, optionally, when the tool is used as a lock-remover, the inner walls of the lock's hollow wing-nut cylinder cap. When used as a lock-forcing opener, the combination tool is placed in position on the lock cylinder's face and a conventional wrench gripping the tool's hexagonally-shaped portion is turned to create torque applied by the tool's projections against the walls of the lock's recesses, forcing the lock cylinder to turn to its ON position and start the vehicle's engine.
