Abstract
Abstract A box frame for the display of fabric prints and the like, comprising a shallow, closed box formed from folded sheet material, with the fabric stretched over the front face of the box and stapled or otherwise secured to the rear surface. The rear of the box is formed by overlying flap pairs extending inward from opposite sides of the box, each flap pair having flap tabs formed by folded down edges of the flaps, the tabs abutting each other and the inside front surface and extending across each other to stiffen the box. The tabs of the outer flap pair lock into slots formed in the underlying flap pairs to secure the flaps in the folded position. Slotted perforations are provided through flap pairs to enable ready wall mounting of the box frame.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
232 words
Display apparatus for providing a rigid mounting for display of flexible material items such as fabric prints and the like, said apparatus comprising: a closed three-dimensional polygonal box formed of folded sheet material, said closed polygonal box including a front surface area formed by the outer surface of a central region of said sheet material; a corresponding number of box sides extending rearwardly of said front surface formed by portions of said sheet material folded together away from said central region; oppositely extending flap pairs formed by sections of said sheet material contiguous to said folded box sides and folded to extend toward each other and spaced from said central region, at least one flap pair including flap tabs consisting of inwardly bent folded portions of each of said flaps of sufficient depth and length to engage substantially the full width of the inside of said central region parallel to said sides, said flaps being of a length to position said flap tabs on opposite flaps in abutment with their outer juxtaposed surfaces; means for securing said flaps and flap tabs in their respective folded positions; and flexible material being stretched over the front surface of said central region and attached to the flap pairs on the rear of the box whereby to provide a display in combination with the three-dimensional box which serves as an integral rigid support for the material.
Claim 2
Dependent Claim

Display apparatus for providing a rigid mounting for display of flexible material items such as fabric prints and the like, said apparatus comprising: a closed three-dimensional polygonal box formed of folded sheet material, said closed polygonal box including a front surface area formed by the outer surface of a central region of said sheet material; a corresponding number of box sides extending rearwardly of said front surface formed by portions of said sheet material folded together away from said central region; oppositely extending flap pairs formed by sections of said sheet material contiguous to said folded box sides and folded to extend toward each other and spaced from said central region, at least one flap pair including flap tabs consisting of inwardly bent folded portions of each of said flaps of sufficient depth and length to engage substantially the full width of the inside of said central region parallel to said sides, said flaps being of a length to position said flap tabs on opposite flaps in abutment with their outer juxtaposed surfaces; means for securing said flaps and flap tabs in their respective folded positions; and flexible material being stretched over the front surface of said central region and attached to the flap pairs on the rear of the box whereby to provide a display in combination with the three-dimensional box which serves as an integral rigid support for the material.
Claim 3
Dependent Claim
60 words
The display apparatus according to claim 1 wherein said box is formed in a rectangular shape and is provided with two of said flap pairs extending normally to each other, each flap pair including said flap tab portions whereby said crossing pattern of said abutting flap tabs extends at right angles to each other to stiffen said box frame structure.
Claim 4
Dependent Claim
56 words
The display apparatus according to claim 1 wherein one of said flap pairs underlies the other of said flap pairs and wherein each of said outer flap tabs extends inwardly through slots formed in each of said inner flap pairs, said slots extending to be a length less than the length of said inner flap pairs.
Claim 5
Dependent Claim
53 words
The display apparatus according to claim 3 wherein said means securing said flap pairs in said folded position comprises a protuberance formed on each of said outer flap tabs adapted to interlock with said slot openings in said inner flap pairs to provide said means holding said flap pairs in the folded position.
Claim 6
Dependent Claim
46 words
The display apparatus according to claim 1 wherein said at least one flap pair is provided with orthogonally extending slotted openings extending through said flaps, whereby said box frame may be mounted to the wall surface by positioning wall fasteners in either of said slotted openings.
Claim 7
Dependent Claim
15 words
The display apparatus according to claim 1 wherein said folded sheet material consists of paperboard
Claim 8
Dependent Claim
62 words
The display apparatus according to claim 4 wherein both of said flap pairs are formed with slotted openings extending in orthogonal directions to each other, which slotted openings are aligned with said flap pairs in said folded position, whereby said box frame may be mounted to a wall surface by wall fasteners extending into said aligned slotted openings in said flap pairs.
Claim 9
Dependent Claim
13 words
The display apparatus according to claim 6 wherein said paperboard comprises corrugated cardboard.
