Abstract
An electronic tongue strike mechanism which can be mounted in a door frame is disclosed. The electronic tongue strike mechanism has a main mounting bracket which is mountable to a door frame, a tension plate which is pivotally mounted to the main mounting bracket a tongue strike mounted on the tension plate for engaging a door bolt and a pressure sensor mounted on the tension plate to sense relative movement between the tension plate and the main mounting bracket caused by the door bolt being urged against the tongue strike. The pressure sensor feeds electronics which operate to control release of the tongue strike.

An electronic tongue strike mechanism comprising:
- a main mounting bracket which is mountable onto a door frame;
- a tension plate which is pivotally mounted to the main mounting bracket;
- a tongue strike mounted on the tension plate for inwardly engaging a door bolt;
- and
- a pressure sensor mounted on the tension plate to sense relative movement between the tension plate and the main mounting bracket caused by the door bolt being urged against the tongue strike.
The electronic tongue strike mechanism of claim 111 further comprising a tongue strike backstop mounted between the upper and lower tongue strike support brackets behind the tongue strike for limiting rotational movement of the tongue strike.
A method of operating a door to allow entry to a secure area comprising the steps of:
- exerting pressure on the door to activate a pressure sensor on an electronic tongue strike mechanism to become active;
- emitting a electromagnetic signal from the electronic tongue strike mechanism in response to the activated pressure sensor;
- activating a remote control device in response to the electromagnetic signal;
- emitting a coded signal from the remote control device upon its activation;
- receiving the coded signal by electronic tongue strike mechanism and actuating a tongue strike mechanism in response thereto to operate the door.
An electronic tongue strike mechanism comprising:
- a main mounting bracket which is mountable onto a door frame;
- a tongue strike disposed on the main mounting bracket for inwardly engaging a door bolt;
- and
- a tongue strike latch which is engageable with the tongue strike through an opening in a tongue strike backstop.
