1. A unitary structure for forming into a hinge, when folded comprising:
- a) a base element having an upper surface and a lower surface, wherein said upper surface has a first elevation and a second elevation;
b) a first projecting element of the structure projecting from said base element proximate said second elevation;
c) a first extension of the structure extending from said first projecting element thereby forming a third elevation;
d) a first depending element of the structure depending from said first extension;
e) a second extension of the structure extending from said first depending element thereby forming a fourth elevation;
f) a second projecting element of the structure projecting from said second extension of the structure wherein said second projecting element is substantially the same thickness as said first depending element and thinner than said second extension;
g) a third extension of the structure extending from said second projecting element thereby forming a fifth elevation;
h) a second depending element of the structure depending from said third extension of the structure;
i) a fourth extension of the structure extending from said second depending element, wherein said fourth extension has an upper surface and a lower surface, wherein said upper surface of said fourth extension forms a sixth elevation at the same elevation as said second elevation and a seventh elevation at the same elevation as said first elevation, so that when the hinge is folded, said lower surfaces are brought proximate each other.

8. A unitary structure for forming into a hinge when folded, comprising:
-
a) a substantially straight length of the structure having an upper surface and a lower surface; b) a first substantially right angle formed at the end of said straight length, wherein said right angle has a projection therefrom; c) a second substantially right angle formed at the end of the said first angle projection, wherein said second right angle has an extension extending therefrom in the direction opposite said straight length; d) a third substantially right angle formed at the end of said second angle extension, wherein said third right angle has a depending element depending therefrom in the same direction as said first angle projection; e) a fourth substantially right angle formed at the end of said third angle depending element, wherein said fourth angle has an extension extending therefrom in the same direction as said second angle extension; f) a fifth substantially right angle formed at the end of said fourth angle extension, wherein said fifth angle has a projection therefrom in the same direction as said first angle projection; g) a sixth substantially right angle formed at the end of said fifth angle projection, wherein said sixth angle has an extension extending therefrom in the same direction as said second angle extension and said fourth angle extension and in the same plane as said second angle extension; h) a seventh substantially right angle formed at the end of said sixth angle extension, wherein said seventh angle has a depending element depending therefrom in the same direction as said third angle projection; i) an eighth substantially right angle formed at the end of said seventh angle depending element, wherein said eighth angle has an extension extending therefrom in the same direction as said fourth angle extension and said sixth angle extension and in the same plane as said straight length, wherein said eighth angle extension has an upper surface and a lower surface;
so that when said structure is folded, said lower surface of said straight length is proximate said lower surface of said eighth angle extension. - View Dependent Claims (9, 10, 11, 12, 13, 14)
