US 2018/0328081 A1 · ELECTRONIC LOCKING DEVICE

Abstract

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.

Dependent claims

An electronic locking device comprising:

a cylinder defining a cylindrical space;
a plug received in said cylindrical space, said plug including at least one annular channel formed therein;
at least one solenoid including at least one shuttle movable between a first and a second position;
at least one control device for receiving a signal from a key and selectively activating said solenoid in response to a correct said signal;
at least one blocking element inserted into said cylinder, said blocking element extending into said cylindrical space and into said annular channel, said blocking element receiving and allowing linear movement of said shuttle and preventing rotation of said shuttle within said annular channels, wherein in a locked condition said shuttle is contained only partially within said annular channels thereby preventing rotation of said plug within said cylinder and in an unlocked condition said shuttle is contained within said annular channels thereby allowing rotation of said plug within said cylinder.
