Abstract
Abstract A plurality of longitudinal parallel seam lines (3) and a plurality of lateral parallel seam lines (2) are formed on a sheet in lattice form. By selectably dimensioning and separaing and/or bending the sheet according to the present invention along the longitudinal and lateral parallel seam lines, it is possible to define any desired threedimensional shape, without use of scissors, a knife, or a ruler. The sheet is best applicable to make packing boxes of various sizes or shapes at a store or model (miniature) buildings, animal hobby toys, etc.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
74 words
A selectable size folding sheet which comprises: (a) a plurality of first parallel. seam lines spaced at regular intervals; and (b) a plurality of second parallel seam lines perpendicular to said first seam lines and spaced at regular intervals, said first seam lines and said second seam lines serving as lines and axes of separation and/or bending, whereby said folding sheet can be selectively dimensioned and folded to define a desired three- dimensional shape.
Claim 2
Dependent Claim
74 words
A selectable size folding sheet which comprises: (a) a plurality of first parallel. seam lines spaced at regular intervals; and (b) a plurality of second parallel seam lines perpendicular to said first seam lines and spaced at regular intervals, said first seam lines and said second seam lines serving as lines and axes of separation and/or bending, whereby said folding sheet can be selectively dimensioned and folded to define a desired three- dimensional shape.
Claim 3
Dependent Claim
31 words
A selectable size folding sheet as set forth in claim 1, wherein said first and second parallel seam lines are defined by a great number of perforations formed in said sheet.
Claim 4
Dependent Claim
36 words
A selectable size folding sheet as set forth in claim 1, wherein said first and second parallel seam lines are defined by a great number of upward concave notches arranged on one surface of said sheet.
Claim 5
Dependent Claim
39 words
A selectable size folding sheet as set forth in claim 1, wherein said first and second parallel seam lines are defined by a great number of double upward- and downward-concave notches arranged on both the surfaces of said sheet.
Claim 6
Dependent Claim
39 words
A selectable size folding sheet as set forth in claim 1, wherein said first and second parallel seam lines are defined by a great number of alternating upward-, and downward-concave notches arranged on both the surfaces of said sheet.
Claim 7
Dependent Claim
59 words
A selectable size folding sheet as set forth in. claim 1. wherein said first parallel seam lines are coarse along the paper grain of said sheet and said second parallel seam lines are fine perpendicular to the paper grain of said sheet, whereby said folding sheet- can be separated and/or bent by substantially the same separating and/or bending force.
Claim 8
Dependent Claim
47 words
A selectable size folding sheet as set forth in claim 1, which further comprises a plurality of third parallel seam lines spaced at regular intervals and passing the points of intersections of said first and second parallel seam lines, said third parallel seam lines are the coarsest.
Claim 9
Dependent Claim
26 words
A selectable size folding sheet as set forth in claim 1, wherein the spaced intervals of said first and second parallel seam lines are 10 millimeter.
Claim 10
Dependent Claim
26 words
A selectable size folding sheet as set forth in claim 1, wherein the spaced intervals of said first and second parallel seam lines are 20 millimeter.
Claim 11
Dependent Claim
32 words
A selectable size folding sheet as set forth in claim 1, where each of said first and second parallel seam lines is repeatedly designated by numerals from 1 to 10 in order.
