ABSTRACT:
A push release door opener for aluminum storm and screen doors having a push handle comprising a lightweight, inexpensive aluminum push rail with a C-shaped cross-section with top and bottom grooves forming a track and having a first and second end, an adjusting bar slidably attached through the first push rail end to the push rail and slidable in the track formed by the top and bottom grooves, the adjusting bar having a first end which is slidable in the track and a door-attaching end which extends away from the end of the push rail, the adjusting bar further having a Z-shaped bend formed in the door-attaching end for providing a desirable offset of the push rail from the door and for enhancing the inherent resilience of the adjusting bar, the door-attaching end of the adjusting bar being attached to a solid part of the door at the hinge side of the door opposite the handle and at substantially the same level as the handle, and a U-shaped hook slidable in the track of the push rail and operative to connect the second push rail end to the handle of the door whereby a gentle push against the push rail with any part of the body is effective to release the push handle latch to open the door, thereby freeing the hands for other purposes. The push release door opener is easily installed within minutes by one having little or no mechanical experience. There is no interference with the locking and latching mechanism on the door. The push release door opener is further characterized by its versatility, fitting most door widths, and by its ease of removal, if necessary, for changing the screens and storm windows.
