ELECTROMECHANICAL LOCK (MODIFICATIONS) Russian patent published in 2001 - IPC

FIELD: locksmith's work. SUBSTANCE: electromechanical lock has a closing cross-bar installed in the body, and a rotary bush with a tongue. Installed in the cross-bar groove is an electromagnet with an armature engageable with the tongue of the rotary bush so that at a simultaneous application of voltage to the electromagnet and rotation of the rotary bush the tongue of the rotary bush gets engaged with the armature. The armature is held by the electromagnet, and rotation of the rotary bush causes displacement of the cross-bar. When the electromagnet is deenergized and the rotary bush is rotating, the tongue of the rotary bush pushes the armature upwards without engagement with it, and rotation of the rotary bush does not cause displacement of the cross-bar. EFFECT: design of the lock provides for its external power supply and transmission of the statistic data on lock operation to the computer network. 10 cl, 6 dwg _
