An electronic lockbox uses a rotary actuator with multiple positions to achieve multiple locking states. Multiple positions of the actuator are detected, using optical sensors. The locking mechanism includes an outer sleeve and an inner cylindrical barrel that are coupled with torsion springs. The lockbox has a shackle and a key bin that are retained by the inner barrel when in the locked state, and the barrel can be rotated to either release the shackle or to release the key bin that typically holds a building's key.

This invention relates to a padlock assembly 1 including a body 2 with a hand engageable portion 4 that is external to the body 2 forming part of an actuator mechanism 5. The actuator mechanism 5 is electrically controllable to adjust between an operable condition and an inoperable condition to adjust a condition of a lock mechanism 31.

A portable lock comprises a lock body and at least one securing part, in particular a U hoop or a bolt, wherein the at least one securing part can be selectively locked to the lock body or released from the lock body. In this respect, the lock body comprises at least one introduction opening for introducing the at least one securing part into the lock body; at least two sensors for detecting the securing part introduced into the lock body and for generating corresponding detection signals; an evaluation and control circuit for determining a current occupancy state of the lock body in dependence on the generated detection signals, wherein the evaluation and control circuit is configured to associate different combinations of generated detection signals with different occupancy states of the lock body; and an electromechanical locking device that has at least one electrically drivable latch for locking the at least one securing part in the at least one introduction opening, wherein the evaluation and control circuit is configured to control the locking device.

An electronic lockbox including a key bin having an embedded insert. The insert is embedded during a die cast process. The insert enhances the attack resistance of the lockbox from hammering, chiseling, and drilling attacks. The insert includes “3D features” that help with the casting process and attack resistance, including at least one through-hole, at least one slot, and at least one ridge. A housing portion is constructed over multiple drawing stages to increase its hardness and strength, thereby increasing resistance to prying attacks.

The present invention is an improved electronic lock for use on cargo containers, storage trailers, tractor-trailers, houses, sheds, vehicles or other structures. The improved electronic lock communicates with a mobile wireless communication device such as a smart phone, and may be selectively locked or unlocked. The improved electronic lock may be configured as two independent locking mechanisms within one locking unit and having a traditional shackle-style locking portion and another locking shank portion for securing (or sealing) door latch bars commonly found on tractor-trailer cargo doors. The improved electronic lock further includes a Global Positioning System (GPS) so that the secured (or sealed) cargo container or trailer can be tracked by the improved lock device's location.

A bottom opening password lock comprises a lock case and a liner arranged in the lock case as well as a shackle connected with a top of the lock case, and a fork, a password assembly and a locking mechanism are installed and arranged on the liner; the password assembly comprises a pin shaft and a second spring, a clutch sleeve, a password wheel, a code adjusting lever and a washer sleeved on the pin shaft. One end of the second spring is abutted against an inner side of the washer, and the other end is abutted against the clutch sleeve away from the code adjusting lever. The bottom opening of the present invention adjusts a password through the code adjusting lever, the code adjusting lever is toggled manually, the code adjusting lever directly pushes the clutch sleeve to move and separate from the password wheel, and the pin shaft is motionless. The code adjusting lever is located at the bottom of a lock body, which is convenient to adjust, may not be lost, and is more convenient for users to use.

Examples of devices are described herein. In some examples, a device may include a plurality of electronic elements. In some examples, each of the electronic elements is mechanically interlockable to another of the electronic elements. In some examples, each of the electronic elements is to control a lock state based on a broadcast signal to modify a shape of the device to a predetermined target shape.

There is provided a lock which can include a shackle which can be moved between an unlocked configuration and a locked configuration. A locking mechanism can be carried by the lock. The locking mechanism can include a guard which can be actuated in a manner such that an access region can be defined to facilitate movement of the shackle such that the shackle can be moved to be in an unlocked configuration. The guard can also be actuated in a manner so as to block the access region to impede movement of the shackle when in the locked configuration such that the shackle is maintained in the locked configuration.
