An exemplary lock apparatus generally includes a shackle, a crossbar, a lock device, a first bolt, and a trigger. The lock device has a locked state in which the lock device retains a spindle in a spindle locking position, and an unlocked state in which the lock device does not prevent movement of the spindle to a spindle unlocking position. The first bolt is engaged with the spindle such that movement of the spindle between the spindle locking position and the spindle unlocking position drives the first bolt between a first locking position and a first unlocking position. The trigger is movably mounted in the crossbar for movement between an engagement position, in which the trigger maintains the spindle in the spindle unlocking position, and a disengagement position, in which the spindle is operable to move to the spindle locking position.

A locking system and method for a movable freight container door comprises an electronic module and a mechanical lock element. The mechanical lock element comprises a shaft, at least of portion of which is configured to be inserted through an aperture in the electronic module, across a door handle retention region, and into a cavity in the electronic module. The shaft is securely retained in the electronic module by moving a lock mechanism to a locked position. At least one magnetic field sensor in the electronic module is used to read the position of the shaft in the cavity by sensing or not sensing one or more magnets in the shaft. A wireless communication component in the electronic module wirelessly transmits magnetic field sensor information.

Disclosed is a Sleeve Stop Lock that is a portable, removable, non-damaging door lock that can be used to secure almost any inward swinging door from the outside. The apparatus consists of three components: a sleeve, a stop, and a lock. The “sleeve” component fits around the edge of a door. It is installed while a door is open. With the door closed, the “stop” makes contact with the door frame once attached to the sleeve thus preventing the door from swinging inward. The “lock” mechanism then securely binds all of the components together. The combination of these three elements (sleeve, stop and lock) prevent potential intruders (including housekeeping) from entering and invading the privacy of an unoccupied room.

A padlock shroud is described for protecting a padlock. For example, one implementation of a padlock shroud comprises: a shroud body having a chamber with an opening accessible to a padlock body, the opening formed in a lower portion of the shroud body, wherein to engage a padlock with the shroud, the padlock body is inserted into the chamber through the opening, apertures formed through an upper portion of the shroud body and having a spacing substantially equal to a spacing of legs of a shackle to be engaged with the padlock through the apertures, a shackle protector having first and second connection points adjacent to the apertures and extending upward from the upper portion of the shroud body at a length at least substantially equal to a length of the legs of the shackle, and a press pin aperture formed on a side of the shroud body and positioned to allow a press pin to be inserted beneath the padlock body when the padlock body is fully inserted into the chamber.

The present disclosure provides an intelligent lock. In an embodiment, the intelligent lock includes: a lock body having a lock hole; a lock lever, the lock lever being capable of being plugged into and being unplugged out of the lock hole of the lock body; a first restricting member movably provided inside the lock body, and capable of being moved and latched into the lock hole to restrict the plugging of the lock lever into the lock hole or the unplugging of the lock lever out of the lock hole; a second restricting member movably provided inside the lock body, and capable of being abutted against the first restricting member so as to restrict a movement of the first restricting member; a detecting device provided in the lock body, and configured to detect the plugging operation of the lock lever into the lock hole or the unplugging operation of the lock lever out of the lock hole and to send a detection signal; and a main control element communicatively connected to the detecting device, and configured to determine a locking state of the intelligent lock in accordance with the detection signal sent by the detecting device.

A locking module for selectively coupling a first component and a second component of a lockable device includes a locking member rotatable about an axis between a rest position and an actuated position. An engagement member is movable between a locked position and an unlocked position. The engagement member is configured to cooperate with the locking member to selectively release the second component.

An anti-theft apparatus that attaches to a shift lever and a foot rest of a motorcycle includes a shackle that is sized and shaped to extend from the foot rest to the shift lever. The shackle has an open end, a second end opposite of the open end, and two elongate arms that extend between the second end and the open end. A locking mechanism engages with the open end of the shackle to lock the shackle into place around the foot rest and the shift lever. A lock plate is coupled to one of the elongate arms of the shackle. A cross bar plate removably attaches to the open end of the shackle and is configured for being positioned between the locking mechanism and the shift lever when the apparatus is attached to the motorcycle. When the apparatus is attached to the motorcycle, the motorcycle shift lever cannot be operated, thereby deterring theft of the motorcycle.

A wireless ultra-low power portable lock may be realized as a lock apparatus including: a locking mechanism having at least locked and unlocked states, the locking mechanism operable to provide physical resistance to being unlocked when in the locked state; an actuator operable to move the locking mechanism from the locked state to the unlocked state in response to a received signal; and a controlling unit configured to control the actuator and to receive one or more signals from one or more devices external to the lock apparatus.

The puck lock security hasp system includes a base, curved upright walls extending from the base, flanges extend outwardly from the curved upright walls, and a U-shaped lock. A standard puck lock can be secured on the base within a space between the curved walls. The U-shaped lock can be positioned and secured over the curved walls to block the keyhole of the puck lock. In some embodiments, the U-shaped lock may include: a hollow pipe filled with a dye or paint for marking a thief cutting into the lock; sections of hollow pipe in the straight parts of the shackle for resisting sawing of the shackle; and/or multiple keyholes, with only one being operable to open the lock.

A lock for permanent attachment to a movable freight container cargo door as a replacement for a prior art hasp or a prior art keeper. The lock is configured for permanent attachment to the cargo door using pre-existing hole locations for the prior art hasp or keeper. The lock comprises a straight shackle and a c-shaped lock body and is configured to retain a door handle between the shackle and the back of the c-shaped lock body. The shackle is locked into the lock body using a shackle lock element that engages with a groove in the shackle. The shackle groove is perpendicular to the shaft of the shackle. The shackle lock element is pressed into the groove using by one or more springs in linear direction that is perpendicular to the length of the shackle and perpendicular to the groove, and released from the groove through by a lock module, which could be a lock cylinder or an electronic lock module. Axial movement of the shackle to prevent the shackle from being completely removed from the lock body is accomplished by a screw in the lock body that rides into a longitudinal slot in the shaft of the shackle.
