Abstract
Abstract A cabinet is disclosed formed from a single sheet of board, laminated on at least one side with a finished material. The substrate may be so grooved that the laminate forms a living hinge which can be folded to form a cabinet with a bottom, two opposed sides, and a top from a single sheet. A framed front face plate comprises a pair of stiles at the vertical side edges, and a top rail and a bottom rail having mitered joints, all being joined to the cabinet members by living hinges. The cabinet is characterized by the absence of raw edges, and no necessity for further finishing. Optionally, a mullion may be positioned in the center. The mullion is secured to the top rail and bottom rail by means of dowels, and the rear face of the mullion can receive selectively locatable shelf supports along with and cooperating with selectively positioned shelf supports on the sidewalls. A back is framed into position when the side and top are folded into position and held in place by means of grooves in the rear portion of the sidewalls, top, and bottom.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
178 words
A cabinet comprising, in combination, a single blank formed of a substrate and at least one laminated face by grooving the same to define a living hinge of laminate between ones of a first sidewall, a bottom adjoining the first said sidewall, a second sidewall adjoining said bottom, and a top joining said second sidewall for closing into rectangular enclosure, a pair of stiles extending from the vertical front edge of each of said first sidewall and second sidewall and joined thereto by a living hinge, a top rail extending downwardly from said top and joined thereto by a living hinge, a bottom rail extending upwardly from said bottom adjoined thereto by a living hinge, each of said top rail, bottom rail, and stiles having complementary ends proportioned for abutting relationship with the adjacent rails and stiles whereby the front portion of the cabinet is framed, each of said top rail, bottom rail, and stiles having a double groove and double plate to define a reversely folded back part abutting its adjacent sidewall and masking all raw edges.
Claim 2
Dependent Claim
178 words
A cabinet comprising, in combination, a single blank formed of a substrate and at least one laminated face by grooving the same to define a living hinge of laminate between ones of a first sidewall, a bottom adjoining the first said sidewall, a second sidewall adjoining said bottom, and a top joining said second sidewall for closing into rectangular enclosure, a pair of stiles extending from the vertical front edge of each of said first sidewall and second sidewall and joined thereto by a living hinge, a top rail extending downwardly from said top and joined thereto by a living hinge, a bottom rail extending upwardly from said bottom adjoined thereto by a living hinge, each of said top rail, bottom rail, and stiles having complementary ends proportioned for abutting relationship with the adjacent rails and stiles whereby the front portion of the cabinet is framed, each of said top rail, bottom rail, and stiles having a double groove and double plate to define a reversely folded back part abutting its adjacent sidewall and masking all raw edges.
Claim 3
Dependent Claim
101 words
In the cabinet of claim 1, said blank being formed from a material which has been laminated on both faces with a finished material, each of said elements being separated from the other by a V groove penetrating one of said lamination and terminating at approximately the back of the second laminate whereby the second laminate becomes a living hinge, each and every element being formed and proportioned so that when folded into a quadrilateral unit no raw portions of the blank appear and the interior is fully laminate finished as is the exterior thus requiring no further finishing upon installation.
Claim 4
Dependent Claim
53 words
In the cabinet of claim 1, a rear frame defined by extensions from each of said top, first sidewall, bottom and second sidewall extending centrally and mitered at their end portions, at least one of said members of said rear frame serving as a hang rail for securing the cabinet to the wall.
Claim 5
Dependent Claim
135 words
In the cabinet of claim 1, a plurality of back retaining grooves defined in the rear edge portion of each of said first sidewall, bottom, second sidewall, and top, a back proportioned to be enveloped by the groove of said first sidewall, bottom, second sidewall, and said back, and a rear frame defined by rearward extensions from each of said first sidewall, bottom, second sidewall, and top, said frame extensions having complementary end portions to meet in framelike relationship at the rear of the cabinet, and means for securing said frame to said back, whereby any of the four members of the rear frame may serve as a hang rail and securing members may pass through the double thickness of the back and frame and then engage the surface in which the cabinet is mounted.
Claim 6
Dependent Claim
53 words
In the cabinet of claim 2, a rear frame defined by extensions from each of said top, first sidewall, bottom, and second sidewall extending centrally and mitered at their end portions, at least one of said members of said rear frame serving as a hang rail for securing the cabinet to the wall.
Claim 7
Dependent Claim
135 words
In the cabinet of claim 2, a plurality of back retaining grooves defined in the rear edge portion of each of said first sidewall, bottom, second sidewall, and top, a back proportioned to be enveloped by the groove of said first sidewall, bottom, second sidewall, and said back, and a rear frame defined by rearward extensions from each of said first sidewall, bottom, second sidewall, and top, said frame extensions having complementary end portions to meet in framelike relationship at the rear of the cabinet, and means for securing said frame to said back, whereby any of the four members of the rear frame may serve as a hang rail and securing members may pass through the double thickness of the back and frame and then engage the surface in which the cabinet is mounted.
Claim 8
Dependent Claim
135 words
In the cabinet of claim 3, a plurality of back retaining grooves, defined in the rear edge portion of each of said first sidewall, bottom, second sidewall, and top, a back proportioned to be enveloped by the groove of said first sidewall, bottom, second sidewall, and said back, and a rear frame defined by rearward extensions from each of said first sidewall, bottom, second sidewall, and top, said frame extensions having complementary end portions to meet in framelike relationship at the rear of the cabinet, and means for securing said frame to said back, whereby any of the four members of the rear frame may serve as a hang rail and securing members may pass through the double thickness of the back and frame and then engage the surface in which the cabinet is mounted.
Claim 9

Claim 12
Dependent Claim
199 words
A cabinet comprising, in combination, a single blank formed of substrate and at least one laminated face by grooving the same to define a living hinge of laminate between ones of a first sidewall, a bottom adjoining the first sidewall, a second sidewall adjoining said bottom and a top joining said second sidewall for closing into a rectangular enclosure, means defining a frame at the front portion of said enclosure, each of said means extending inwardly from the adjoining sidewall, bottom and top, and each having complementary ends for interfitting with the ends of adjacent such means, back framing means extending inwardly and secured by a living hinge to each of said sidewalls, bottom and top, a back for closing the rear of the cabinet, and groove means adjoining the rear framing means living hinge, whereby upon folding all of said sidewalls, bottom and top to form the rectangular enclosure, the back is locked in place in the grooves provided at the rear of the cabinet, and overlappingly secured by the back framing means, and the exterior of the cabinet is defined by the sidewalls and back frame thereby minimizing the space into which the cabinet may be fitted.
