An electronic locking device including a cylinder and a plug located in the cylinder. Within the plug is a solenoid with a pair of shuttles which move in opposite directions. A control processor controls the solenoids activating the shuttles when connected to the correct key. Blocking elements for each shuttle are inserted through the cylinder and into annular channels in the plug. The blocking elements receive and allow linear movement of the shuttles but prevent their rotation within the annular channels. In a locked condition the shuttles are contained only partially within the annular channels thereby preventing rotation of the plug within the cylinder but in an unlocked condition the shuttles are contained within the annular channels thereby allowing rotation of the plug. The plug also includes a weakness defining a point at which it will break upon application of excessive force.

Electronic locking device

A locking device and system are disclosed. The locking device includes a barrel within which sets a plug. A plurality of pins sit in pin pathways that extend partially through the barrel and plug and the pins prevent rotation of the barrel within the plug when the ends of the pins are not aligned with a shear line. One of the pins has a recess formed therein within which a locking ball can sit. The engagement or otherwise of the locking ball in the recess is controlled by a linear actuator. When the linear actuator allows the locking ball to disengage the recess the pin with the recess in can engage the key and a line the end of the pin with the shear line.

Locking device

An improved locking device, such as a combination padlock, is provided in which the re-coding thereof can be carried out in a convenient and/or efficient manner. The locking device has a body including a plurality of dials disposed to surround a lock member in an axially spaced relationship therealong. Relative axial sliding movement is possible between the dials and the lock member between a locked position and a release position. The lock member has at least one generally radially extending exterior locking configuration received in a corresponding first location at one side of a dial in the locked position, and in a corresponding second location within a dial in the release position. Each dial, in the release position, is angularly movable relative to the locking configuration so as to allow re-coding the dial.
