Abstract
Abstract A metal plate for fastening furniture together is comprised of a strip of metal having two longitudinal apertures sequentially located along the length of the strip and flanges formed along the longitudinal edges of the strip. The flanges reinforce the strip making bending of the strip more difficult. Screws inserted through the apertures captivate the plate to adjacent pieces of furniture. The longitudinal apertures allows continuously variable selection of distances between mounting screws.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
123 words
A metal plate furniture fastening for fastening two adjacent pieces of furniture with screws being used to secure said plate to said furniture, the plate comprising at least two screws in combination with: a longitudinal metal strip having an enclosed longitudinal aperture of uniform width for receiving said screws, said aperture being of sufficient length to substantially overlap each of the two adjacent pieces of furniture permitting a continuous selection of two screw locations along said aperture, and flanges formed by bending the longitudinal edges of said strip substantially perpendicular to said strip, whereby the two screws are inserted through said aperture with at least one screw securing each piece of furniture to said strip, thereby fastening said furniture together with said plate.
Claim 2
Dependent Claim
123 words
A metal plate furniture fastening for fastening two adjacent pieces of furniture with screws being used to secure said plate to said furniture, the plate comprising at least two screws in combination with: a longitudinal metal strip having an enclosed longitudinal aperture of uniform width for receiving said screws, said aperture being of sufficient length to substantially overlap each of the two adjacent pieces of furniture permitting a continuous selection of two screw locations along said aperture, and flanges formed by bending the longitudinal edges of said strip substantially perpendicular to said strip, whereby the two screws are inserted through said aperture with at least one screw securing each piece of furniture to said strip, thereby fastening said furniture together with said plate.
Claim 3
Dependent Claim
128 words
A fastening plate for joining two adjacent pieces of furniture together utilizing screws, said plate comprising: a longitudinal metal strip having at least two completely enclosed longitudinal apertures of uniform width for permitting a continuous selection of screw locations along the entire length of each aperture, said apertures extending sequentially along the length of the strip, each of the apertures being of sufficient length to substantially overlap one of the two adjacent pieces of furniture, and reinforcing flanges extending along the longitudinal edges of said strip, whereby one screw inserted through an aperture secures one piece of furniture to the strip, the other piece of furniture secured to the strip by a second screw inserted through another aperture, thereby the plate joining two adjacent pieces of furniture together.
Claim 4
Dependent Claim
128 words
A fastening plate for joining two adjacent pieces of furniture together utilizing screws, said plate comprising: a longitudinal metal strip having at least two completely enclosed longitudinal apertures of uniform width for permitting a continuous selection of screw locations along the entire length of each aperture, said apertures extending sequentially along the length of the strip, each of the apertures being of sufficient length to substantially overlap one of the two adjacent pieces of furniture, and reinforcing flanges extending along the longitudinal edges of said strip, whereby one screw inserted through an aperture secures one piece of furniture to the strip, the other piece of furniture secured to the strip by a second screw inserted through another aperture, thereby the plate joining two adjacent pieces of furniture together.
