The rotary rod is connected to a connecting sleeve, the connecting sleeve penetrates through a circuit board to be connected to a deadbolt body, and the deadbolt body matches a plug follower. The intelligent lock device further includes: a door sensor bar and a door sensor plate. The door sensor bar is mounted to the door sensor plate, and a sensor magnet, is mounted at one side of the door sensor plate. The intelligent lock device is novel in structural design. With a door sensor function featuring, strong magnetic sensing, the intelligent lock device can realize automatic locking. Meanwhile, the knob can be detached from and attached to a rear lock body through a strong magnet.

A Temporary Construction door latch/lock is disclosed which is both rugged and economical. The latch includes a half circle flanged housing which acts as a bushing for a journal portion of an operator. The operator includes 2 slots (For 2″¾ and 2″⅜ size doors) to accommodate the latching and the locking pin that serves also as the handle portion to move the latch back to open the door. At the inner end of the operator, a generally cylindrical latch is placed to the interior of the housing through the face of the door to interact with the frame. The latch moves back and force with respect to the housing and is limited in movement by a spring goes inside the housing. The latch is secured to the operator by a latching and a locking pin, which means to prevent the whole latch to come apart. The housing is fixed to the door by securement means which draws the flange of the housing against the exterior of the door.

A closing system for a door or hatch of a motor vehicle includes: a bearing piece and a cylinder lock situated on the bearing piece, the cylinder lock having a cylinder bushing and a cylinder core; and a locking clamp which is held on the bearing piece, engages the cylinder bushing from behind and has a holding lug which is oriented parallel to the cylinder bushing, a fastening screw passing through the holding lug, and the tip of the screw lying in a receiving depression in the cylinder bushing in order to preload the locking clamp against the cylinder bushing. A protective element rests on an outer side of the bearing piece and has at least one retaining lug which is oriented parallel to the cylinder bushing, and the fastening screw also passes through the retaining lug.

A lock and method for locking including an electronic cylinder assembly that may be a direct replacement for a standard cylinder in a standard mortise type door lock housing. The cylinder assembly may include a first shaft rotatably mounted in the core and a second shaft rotatably mounted in the core and coaxial with the first shaft. A clutch is disposed on the first shaft and rotationally fixed to the first shaft but axially shiftable. The cylinder assembly also includes a slider with a finger, where the finger is engaged with the clutch, and a motor is configured to shift the slider axially between a first position and a second position. In the first position, the clutch is disengaged from the second shaft, and in the second position, the clutch is engaged with the second shaft, such that rotation of the first shaft causes rotation of the second shaft.

The present invention, in a non-limiting example embodiment provides a locking apparatus and method for securing locking hardware without the use of a key. In an example embodiment, the apparatus comprises at least a keyless insertion rotatable disk-style, barrel locking apparatus that, in a locked state can be inserted into a securing device without first unlocking, and then, thereafter, locking after insertion. In a nonlimiting example embodiment, unlocking and re-locking requires a key. The present invention, in an example embodiment, also provides features that allow the locking apparatus to enter and exit multiple apertures without requiring a key.

A padlock basic kit for assembling a padlock in a configuration that can be selected from a plurality of configurations, wherein the configurations differ with respect to the type of lock cylinder used in the padlock and optionally additionally with respect to the type of closing hoop used in the padlock, comprises a lock body, at least two different lock cylinder adapters, and a closing plate. In this respect, a first one of the at least two lock cylinder adapters has a reception passage that is configured to receive a lock cylinder of a first type and a second one of the at least two lock cylinder adapters has a reception passage that is configured to receive a lock cylinder of a second type. The lock body has a lock cylinder receiver that extends along a longitudinal direction into the lock body and that is configured to selectively receive the first lock cylinder adapter with a lock cylinder of the first type inserted therein, the second lock cylinder adapter with a lock cylinder of the second type inserted therein, or a lock cylinder of a third type. The closing plate is configured to close the lock cylinder receiver such that it substantially completely covers a respective lock cylinder received in the lock cylinder receiver.
