Abstract
Abstract For use in a drawer, an extruded semi-flexible plastic strip of the same width as the desired drawer height is provided with a smooth side and ridged side having a number of longitudinal flanges which are adapted to be cut transversely with a hand saw, down to the surface of the strip, so that the strip can be bent at the saw cuts to form the vertical sides of a drawer as a single piece of any desired size; the bottom one of said flanges is formed to embrace the edges of a bottom piece for the drawer, the other flanges are adapted to cooperate with a variety of different drawer slides and terminate in a plane so that a front piece can be attached if desired.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
A. For use in making a sliding drawer b. an extruded plastic strip having a width equal to the depth of a desired drawer, said strip being smooth on one side, c. a top flange piece integral with said strip and extending outwardly from the top edge of said strip and turned downwardly at its free edge to form a first reentrant flange strip, d. a channel flange piece extending outwardly from the bottom edge of said strip on the same side as said top flange piece, then bent down and in to form a U-shaped channel at the bottom edge of the strip for retaining an edge of a drawer bottom piece, e. two spaced flanges near the central portion of said strip extending outwardly on the same side of the strip as said top flange and each having a turned edge portion for additional rigidity, f. said turned edge portion of the upper one of said spaced flanges being turned upwardly and a turned edge portion of the lower one of said spaced flanges being turned downardly.
Claim 2
Dependent Claim
179 words
A. For use in making a sliding drawer b. an extruded plastic strip having a width equal to the depth of a desired drawer, said strip being smooth on one side, c. a top flange piece integral with said strip and extending outwardly from the top edge of said strip and turned downwardly at its free edge to form a first reentrant flange strip, d. a channel flange piece extending outwardly from the bottom edge of said strip on the same side as said top flange piece, then bent down and in to form a U-shaped channel at the bottom edge of the strip for retaining an edge of a drawer bottom piece, e. two spaced flanges near the central portion of said strip extending outwardly on the same side of the strip as said top flange and each having a turned edge portion for additional rigidity, f. said turned edge portion of the upper one of said spaced flanges being turned upwardly and a turned edge portion of the lower one of said spaced flanges being turned downardly.
Claim 3
Dependent Claim
77 words
The invention according to claim 1, g. said strip being bent to form at least the two sides and back wall of a drawer, the flanges at the rear corners of said drawer being cut down to the surface of the strip at the two rear corners of said drawer, there being a drawer bottom piece embraced by said lower U-shaped flange, and a front piece having a drawer pull providing the fourth side of said drawer.
Claim 4
Dependent Claim
34 words
The invention according to claim 2, and drawer slide mounting means for mounting said drawer, any of said flange portions being adapted to cooperate with said slide mounting means to support the drawer slidably.
