Abstract
Abstract A free-standing structure having n sides defining n origins where n is greater than two, including a frame having n arch members, two paired arch members fixed at each of n origins; each arch member extending from its origin, across its paired arch member to a different origin across from its initial origin, the arch members forming an n-sided polygon at the top center of the structure; the paired arch members crossing each other on the far side of the polygon relative to the initial origin, the crossing occurring on an axis of symmetry extending through the initial origin and the top center of the structure; and means for securing together the paired arch members at the origins.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
132 words
A free-standing structure having a perimeter and n sides defining n origins on the perimeter, where n is greater than two; a frame having n arch members, two said arch members paired at each of n origins; each such member extending from an initial origin across its paired arch member to an origin different from its pair and across from its initial origin, said arch members forming a self-supporting structure with an n-sided polygon at the top center of the structure; said paired arch members crossing each other on the far side of said polygon relative to the initial origin, said crossing occurring on an axis of symmetry extending through the initial origin and the top center of the structure; and means for securing together said pair arch members at the origins.
Claim 2
Dependent Claim
132 words
A free-standing structure having a perimeter and n sides defining n origins on the perimeter, where n is greater than two; a frame having n arch members, two said arch members paired at each of n origins; each such member extending from an initial origin across its paired arch member to an origin different from its pair and across from its initial origin, said arch members forming a self-supporting structure with an n-sided polygon at the top center of the structure; said paired arch members crossing each other on the far side of said polygon relative to the initial origin, said crossing occurring on an axis of symmetry extending through the initial origin and the top center of the structure; and means for securing together said pair arch members at the origins.
Claim 3
Dependent Claim
16 words
The free-standing structure of claim 1 in which said n sides form an n-sided equilateral polygon.
Claim 4
Dependent Claim
15 words
The free-standing structure of claim 1 in which said arch members are equal in length.
Claim 5
Dependent Claim
19 words
The free-standing structure of claim 1 in which said polygon at the top center is an n-sided equilateral polygon.
Claim 6
Dependent Claim
20 words
The free-standing structure of claim 1 in which said arch members generate a plurality of subdivisions including 2n triangular subdivisions.
Claim 7
Dependent Claim
21 words
The free-standing structure of claim 5 in which said arch members generate n polygonal subdivisions where n is greater than three.
Claim 8
Dependent Claim
27 words
The free-standing structure of claim 1 in which said structure further includes a cover mounted on said arch members for tensioning said frame and rigidifying said structure.
Claim 9
Dependent Claim
22 words
The free-standing structure of claim 1 in which said means for securing includes tunnels in said cover for receiving said arch members.
Claim 10
Dependent Claim
26 words
The free-standing structure of claim 8 in which said means for securing includes tunnels for receiving the ends of said paired arch members at said origins.
Claim 11
Dependent Claim
26 words
The free-standing structure of claim 7 in which said means for securing includes a loop carried by said cover for surrounding and binding said arch members.
Claim 12
Dependent Claim
140 words
A free-standing dome tent having a perimeter and n sides defining n origins on the perimeter where n is greater than two, comprising: a frame having n arch members, two said arch members paired at each of said n origins; each member extending from an initial origins across its paired arch member to an origin different from its pair and across from its initial origin, said arch members forming a self-supporting structure with an n-sided polygon at the top center of the tent; said paired arch members crossing each other in the far side of said polygon relative to the initial origin, said crossing occurring on an axis of symmetry extending through the initial origin and the top center of the tent; and a cover mounted on said arch members for securing and tensioning said frame and rigidifying said tent.
Claim 13
Dependent Claim
140 words
A free-standing dome tent having a perimeter and n sides defining n origins on the perimeter where n is greater than two, comprising: a frame having n arch members, two said arch members paired at each of said n origins; each member extending from an initial origins across its paired arch member to an origin different from its pair and across from its initial origin, said arch members forming a self-supporting structure with an n-sided polygon at the top center of the tent; said paired arch members crossing each other in the far side of said polygon relative to the initial origin, said crossing occurring on an axis of symmetry extending through the initial origin and the top center of the tent; and a cover mounted on said arch members for securing and tensioning said frame and rigidifying said tent.
