Universal mounting plate for door opener
First Claim
1. A substantially rectangular mounting plate for mounting an electrically-operated door opener on a door frame, said mounting plate comprising:
- a plan portion having top and bottom faces, substantially parallel longitudinally oriented side edges one of which is shorter than the other, and substantially parallel transversely oriented end edges,a tab oriented substantially perpendicular to said plan portion, said tab being substantially parallel to and substantially equidistant from said longer side edge and a theoretical extension of said shorter side edge, anda plurality of apertures provided in said plan portion, and an aperture provided in said tab, said apertures being provided for receiving fastening means for fastening said mounting plate to a door frame and to a door opener which is to be mounted thereon.

Abstract
A universally-adaptable mounting plate for mounting an electrically-operated door opener on a door frame. The mounting plate is substantially rectangular, having a plan portion with longitudinally-directed side edges and transversely-directed end edges. A tab is struck from the plan portion at one end of the mounting plate and is positioned substantially perpendicular to the plan portion and substantially equidistant from and substantially parallel with respect to the side edges. The plan portion is provided with both longitudinally-elongated and transversely-elongated apertures for mounting the door opener thereon, and the tab is provided with an aperture for receiving conventional fastening means for affixing the tab to a door frame or door frame jamb. A flattened Z-bracket is conveniently used in combination therewith and mounted transversely near the top edge of the inside of the door for effecting inward opening of the door by means of a conventional roller, rotatably mounted at the end of a door opener actuator arm, operating in rotating contact with the inside surface of the outer upstanding wall of the Z-bracket.
