Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
203 words
A drawer guide adapted to be mounted on a furniture piece to guide the movement of a drawer positioned over the front and rear parting rails of said furniture piece and equipped with a channel shaped slide comprising a unitary elongated plastic element having upper and lower integral horizontally extending flanges integrated by a vertically extending web which extends substantially over the element length to define a generally I-shape and transverse section and equipped with an aperture adjacent each end for receiving a fastener to secure the element to said parting rails, said element further including an integral reinforcement on the underside of said top flange, said reinforcement extending rearward from the front of said guide no more than about 50% of the length of the guide bat at least 3 inches to provide increased resistance to vertical flexure incident to drawer removal, said reinforcement having a planar underside over most of its length to afford good sliding contact with a drawer slide, said reinforcement including a longitudinally extending rib providing said underside and extending on each side of said web, said rib being further integrated to said upper flange and said web by a plurality of longitudinally spaced apart transversely extending webs.
Claim 2
Dependent Claim

A drawer guide adapted to be mounted on a furniture piece to guide the movement of a drawer positioned over the front and rear parting rails of said furniture piece and equipped with a channel shaped slide comprising a unitary elongated plastic element having upper and lower integral horizontally extending flanges integrated by a vertically extending web which extends substantially over the element length to define a generally I-shape and transverse section and equipped with an aperture adjacent each end for receiving a fastener to secure the element to said parting rails, said element further including an integral reinforcement on the underside of said top flange, said reinforcement extending rearward from the front of said guide no more than about 50% of the length of the guide bat at least 3 inches to provide increased resistance to vertical flexure incident to drawer removal, said reinforcement having a planar underside over most of its length to afford good sliding contact with a drawer slide, said reinforcement including a longitudinally extending rib providing said underside and extending on each side of said web, said rib being further integrated to said upper flange and said web by a plurality of longitudinally spaced apart transversely extending webs.
Claim 3
Dependent Claim
153 words
A drawer guide adapted to be mounted on a furniture piece to guide the movement of a drawer positioned over the front and rear parting rails of said furniture piece and equipped with a channel shaped Slide comprising a unitary elongated plastic element having upper and lower integral horizontally extending flanges integrated by a vertically extending web to define a generally I-shape and transverse section and equipped with an aperture adjacent each end for receiving a fastener to secure the element to said parting rails, said element further including an integral reinforcement extending rearward from the front of said guide no more than about 50 percent of the length of the guide but at least 3 inches, said bottom flange being wider than the top flange and the portion thereof aligned with said reinforcement, said bottom flange tapering in width both forwardly and rearwardly from a point intermediate the length of said reinforcement.
