Abstract
The hands-free door opener assembly permits a person to open, close and lock a door by employing a forearm or elbow. The system comprises respective push handle members disposed on both the interior and exterior surfaces of the door. Pushing either handle member functions to pivot a latch out of engagement with a latch plate positioned in the door frame. A door opening spring-biased plate is mounted on the latch plate to provide an assist to open the door when the latch is disengaged. The door is provided with a hands-free locking structure on the interior surface. An occupancy alert is disposed on the exterior surface of the door.

A door assembly, comprising:
- a door having an exterior surface, an interior surface and an opening formed therethrough;
- a handle mechanism pivotally disposed in the opening;
- wherein the handle mechanism pivots in a direction towards the door;
- a movable latch member attached to the handle mechanism, the latch member having a first end and a second end, the second end having a latch head;
- a door jamb disposed adjacent the door;
- a latch plate mounted on the door jamb, the latch plate having an L-shaped cavity formed therein, the cavity having an elongate arm extending upward and defining an edge adapted to engage the latch head to latch the door in a closed position;
- means for moving said latch member to disengage the latch head from the elongated arm of the L-shaped cavity to unlatch the door and allow the door to be opened;
- and
- a spring-biased plate mounted on the door jamb to provide an assist to open the door, wherein said latch head is pivotally mounted on an axis for pivoting movement thereon to engage the latch head with the latch plate to latch the door in a closed position.
