Abstract

Abstract A wall cabinet and method for constructing the same is disclosed wherein vacuum formed, heat fusible polymeric sheet material is used to provide a one-piece body portion and a sealed, hollow door portion. The body portion is provided with an integral mounting flange including perpendicularly extending hinge leaves for pivotal mounting of the door portion. Construction of the hollow, sealed door portion enables two separate sheets of polymeric material to be vacuum formed simultaneously and bonded together along a peripheral seam having a thickness substantially less than two sheets in a manner not distracting from the appearance of the door. Assembly of the body portion and door portion is provided by threading studs into the hinge leaves through vertically opposed corners of one side of the door panel. A latching mechanism is provided between the mounting flange of the body portion and the inside surface of the door panel.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 261 words
A plastic wall cabinet comprising a body portion of plastic sheet material and having a back wall and top, bottom and side walls integral with and extending forwardly of said back wall to provide said body portion with an open front, mounting flange means including upper and lower planar mounting flanges integral with and extending upwardly and downwardly respectively from said top and bottom walls, said upper and lower mounting flanges having upwardly and downwardly facing terminal edges, respectively, extending laterally between said side walls, said planar mounting flanges having corresponding first ends adjacent one of said side walls, upper and lower hinge leaf means each integral with the corresponding one of said upper and lower terminal edges of said first ends of said mounting flanges, each said hinge leaf means including a laterally narrow planar hinge leaf vertically spaced from the corresponding one of said top and bottom walls and extending horizontally forwardly of the corresponding mounting flange, a hollow door for closing said open front, said hollow door comprising front and back panels of plastic sheet material bonded together to provide a central portion bounded by a peripherally continuous hollow portion including a seam between said panel sheets extending about said hollow portion and rearwardly from said front panel toward said back panel, said panel sheets in the area of said seam having rearwardly facing terminal end edges transverse to said seam, and a hinge pin extending through each said hinge leaf and into said hollow portion of said door to pivotally mount said door on said body portion.
Claim 2
Dependent Claim 261 words
A plastic wall cabinet comprising a body portion of plastic sheet material and having a back wall and top, bottom and side walls integral with and extending forwardly of said back wall to provide said body portion with an open front, mounting flange means including upper and lower planar mounting flanges integral with and extending upwardly and downwardly respectively from said top and bottom walls, said upper and lower mounting flanges having upwardly and downwardly facing terminal edges, respectively, extending laterally between said side walls, said planar mounting flanges having corresponding first ends adjacent one of said side walls, upper and lower hinge leaf means each integral with the corresponding one of said upper and lower terminal edges of said first ends of said mounting flanges, each said hinge leaf means including a laterally narrow planar hinge leaf vertically spaced from the corresponding one of said top and bottom walls and extending horizontally forwardly of the corresponding mounting flange, a hollow door for closing said open front, said hollow door comprising front and back panels of plastic sheet material bonded together to provide a central portion bounded by a peripherally continuous hollow portion including a seam between said panel sheets extending about said hollow portion and rearwardly from said front panel toward said back panel, said panel sheets in the area of said seam having rearwardly facing terminal end edges transverse to said seam, and a hinge pin extending through each said hinge leaf and into said hollow portion of said door to pivotally mount said door on said body portion.
Claim 3
Dependent Claim 39 words
The cabinet according to claim 1, wherein said mounting flange means further includes planar mounting flanges integral with and extending laterally outwardly from each said side walls of said body portion coplanar with said upper and lower mounting flanges.
Claim 4
Dependent Claim 22 words
Thy cabinet according to claim 2, wherein said mounting flange means is peripherally continuous about said open front of said body portion.
Claim 5
Dependent Claim 20 words
The cabinet according to claim 3, wherein said hinge pins are interengaged with the corresponding hinge leaf against separation therefrom.
Claim 6
Dependent Claim 27 words
The cabinet according to claim 3, wherein said body portion includes at least one shelf integral therewith and extending between said side walls and said back wall.
Claim 7
Dependent Claim 27 words
The cabinet according to claim 5, wherein said side walls of said body portion include integral support means for positioning a removable shelf within said body portion.
Claim 8
Dependent Claim 37 words
The cabinet according to claim 6, wherein said hinge pins each include a head and a threaded shank, said head engaging the corresponding hinge leaf, and said shank threadedly interengaging the opening in said corresponding hinge leaf.
