    摘要： A door lock includes outer assemblies, latch assemblies and inner assemblies. The inner assemblies has a turning switch, fixing bolts, an interior rose and a detent device that includes an inner plate, a stop plate, a stop seat, a rotating spring, a retaining spring and a sprag. By pressing down the stop plate as the latch bolt is in a casing, a protruding block of the stop seat is engaged with a protruding member of the stop plate. The spindle can not rotate backward and maintains in an unlocked state. After the stop plate is pressed upward, the turning switch returns to a locked state and the latch bolt extends out of the casing. Therefore, the detent device can keep the latch bolt in the casing and keep the lock in the unlocked state.

    摘要： A latch mechanism which includes exterior and interior handle assemblies connected by a bar with a cammed surface such that the latch mechanism can be actuated by pushing, pulling, or turning a handle. Pushing or turning the exterior handle causes the bar to contact a cam follower on a receiver whose edge will rotate a lever to retract a bolt. Also, pulling or turning the interior handle produces the same result. Once the bolt is retracted, and the handle is released, a spring biases the bolt back to the extended position.

    摘要： This invention provides a thumb-piece door latch mechanism which has ergonomic features, is modular and can be used with any escutcheon, can be used with all type locks, and which in the locked door mode provides greater resistance to abusive attack of the door latch mechanism and makes the thumb-piece and latch mechanism more durable and less susceptible to vandalism. The thumb-piece moves linearly up and down and is connected to a thumb-piece guide plate which likewise moves up and down when the thumb-piece is moved. A permissive spring having one end connected to a spindle turn plate and the other end connected to the guide plate moves a rotatably mounted spindle, which in turn rotates a spindle tail and a latch connected to the spindle tail. The permissive spring provides greater resistance to abusive attacks of the door lock and mechanism.

    摘要： An automatic door latch is disclosed. In a preferred embodiment, the latch includes a dead bolt which is automatically moved from a partially retracted or trigger position to a fully extended locking position when a door in which the lock is mounted is closed. When a key is used to unlock the dead bolt from outside of the door, or a finger turn or key is used to unlock the dead bolt from inside of the door, the dead bolt is automatically reset to the trigger position. In a preferred embodiment, the dead bolt lock includes a multi-position switch mounted in the lock housing which engages a contact member mounted on the dead bolt. Retraction of the dead bolt into the housing causes the multi-position switch to engage the contact member and to secure the dead bolt in the trigger position. Subsequent retraction of the dead bolt into the housing causes the multi-position switch to disengage from the contact member, thereby allowing the dead bolt to extend from the housing to the locked position. In a preferred embodiment, a latch restraint assembly is provided which holds the dead bolt in the fully retracted position until the restraint assembly is manually released. The automatic door latch comprises relatively few component parts in comparison with conventional locks, and is preferably compatible with standard predrilled door cut-outs.

    摘要翻译： 公开了一种自动门闩。 在优选实施例中，闩锁包括一个止动螺栓，当其中安装锁的门关闭时，该止动螺栓自动地从部分缩回或触发位置移动到完全伸出的锁定位置。 当使用钥匙从门外部解锁死栓时，或者使用手指转动或钥匙从门内部解锁死栓时，死栓自动复位到触发位置。 在优选实施例中，止动锁定包括安装在锁定壳体中的多位置开关，其接合安装在死栓上的接触构件。 将死螺栓缩回到壳体中使得多位置开关与接触构件接合并将死栓固定在触发位置。 随后将死螺栓缩回到壳体中，多位置开关与接触构件脱离接合，从而允许止螺栓从壳体延伸到锁定位置。 在优选实施例中，提供了一种闩锁约束组件，其将死螺栓保持在完全缩回的位置，直到约束组件被手动释放。 与常规锁相比，自动门闩包括相对较少的部件，并且优选地与标准预钻孔门切口相兼容。
