Universal mounting plate for door opener

A door-opener mounting kit comprising the following elements:

• 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, and
• a 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,
• 2:
• an inwardly-opening door opener adapted to be mounted on said mounting plate, and
• 3:
• a Z-bracket having a flattened-Z cross-section adapted to be mounted transversely on an inside top section of a door, near the top edge thereof, with an outer wall of the Z being upstanding,
• said door opener (2) having an actuating arm carrying a rotatably-mounted roller and adapted to be arranged with said roller in rotating contact with the inside surface of said outer upstanding wall of said Z-shaped bracket (3),
• these elements when assembled into a combination being adapted to enable a door with which utilized to be opened inwardly by engagement of said roller with the said inside surface of said outer upstanding wall of said Z-shaped bracket.

A combination of

• 1:
• a substantially rectangular mounting plate secured 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, and
• a plurality of apertures provided in said plan portion, and an aperture provided in said tab, selected apertures receiving fastening means securing said mounting plate to the door frame and to a door opener which is mounted thereon,
• 2:
• an inwardly-opening electrically-operated door opener mounted on said mounting plate, and
• 3:
• a Z-bracket having a flattened-Z cross-section mounted transversely on an inside top section of a door mounted in said door frame, near the top edge of said door, with an outer wall of the Z being upstanding,
• said door opener (2) having an actuating arm carrying a rotatably-mounted roller and being arranged with said roller in rotating contact with the inside surface of said outer upstanding wall of said Z-shaped bracket (3),
• this combination enabling the said door to be opened inwardly by engagement of said roller with the said inside surface of said outer upstanding wall of said Z-shaped bracket.
