Strike-plate powered mortise lock

An electrified mortise lock configured to receive electrical power through a door strike plate assembly, the lock comprising:

• a mortise lock configured for mounting within a door cutout, the lock including an electrically powered device, a latch bolt assembly and a drive linkage coupling the electrically powered device to a lock linkage configured, in a locked condition, to lock a door lever or knob from actuating the latch bolt assembly from an extended neutral position to retract the latch bolt assembly to allow the door to open;
• an electrical contact coupler system configured to transfer electrical power and control signals between the strike plate of a door frame to the electrically powered device;
• and
• a retraction linkage housed within the mortise lock which synchronizes the movement of a contact coupler unit of the electrical contact coupler system with the latch bolt assembly's retraction, so that when the latch bolt assembly retracts, the contact coupler unit follows suit, retracting into the mortise lock body.

A strike plate assembly for a door, the strike plate assembly comprising:

• a strike plate having a latch bolt opening and an electrical contact opening formed therein;
• a box configured to be assembled to the strike plate in a sandwiched position on the door frame, and having first and second receptacles, with the first receptacle configured to receive a latch bolt of a door, and the second receptacle fitted with electrical contact pads;
• and
• wiring configured to connect the electrical contact pads to an access control power supply and an access controller.
