Abstract
The assembly includes a door with rotatable door handle connected thereto, and a primary door locking mechanism. The door is hinged for opening and closing in a frame disposed in an entry way. The door includes a handle hub lock having a hub locking plate around the handle hub, an elongated slide bolt supported to movement into and out of a recess in the locking plate and a bolt biasing mechanism. That biasing mechanism preferably includes a plunger extending from the leading door edge toward the door jamb and biasable thereby, during door closing, against the bolt to move it into the locked position, and one or more springs connected to the plunger. In one embodiment, one or more electromagnets selectively magnetically bias the slide bolt to the desired locked or unlocked position. The assembly is simple and effective.
