Abstract
Abstract A tent is provided wherein the poles are a series of stressed, arcuate rods which surround a convex polyhedra such as a hemispherical structure. The arcuate rods are approximately in the configuration of segments of circles and they cross at a plurality of points and fit in sockets at each point of crossing and the crossing point is fastened to the membrane forming the tent.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
156 words
A dome structure comprising a plurality of stressed poles each pole being flexed into an arcuate shape to exert a force in a direction which is radially outward of each pole, said poles crossing each other at a plurality of intersections, said poles having terminal ends defining a plane, said poles comprising a plurality of rods held in end-to-end relationship by couplings, a flexible membrane beneath said poles, said couplings being attached to said membrane and holding said poles in intersecting relationship at each of said plurality of intersections, said couplings engaging each of said poles substantially at the point of intersection of said poles and holding intersecting poles relative to each other at said intersections and relative to said membrane in a substantially fixed relationship, said couplings attaching said membrane to said poles and transmitting said outwardly directed force to said membrane, said membrane constituting the sole connection between spaced terminal ends of said poles.
Claim 2
Dependent Claim
156 words
A dome structure comprising a plurality of stressed poles each pole being flexed into an arcuate shape to exert a force in a direction which is radially outward of each pole, said poles crossing each other at a plurality of intersections, said poles having terminal ends defining a plane, said poles comprising a plurality of rods held in end-to-end relationship by couplings, a flexible membrane beneath said poles, said couplings being attached to said membrane and holding said poles in intersecting relationship at each of said plurality of intersections, said couplings engaging each of said poles substantially at the point of intersection of said poles and holding intersecting poles relative to each other at said intersections and relative to said membrane in a substantially fixed relationship, said couplings attaching said membrane to said poles and transmitting said outwardly directed force to said membrane, said membrane constituting the sole connection between spaced terminal ends of said poles.
Claim 3
Dependent Claim
32 words
The structure of claim 1 wherein said poles are composed of a plurality of short rods with coupling members having sockets to receive the ends of said rods in a loose fit.
Claim 4
Dependent Claim
32 words
The structure of claim 2 wherein a pair of crossed coupling members is employed at each intersection with a flexible member extending between the intersection and a fixed point on the membrane.
Claim 5
Dependent Claim
32 words
The structure of claim 2 wherein a pair of crossed coupling members is employed at each intersection with a fixed member extending between the intersection and a fixed point on the membrane.
Claim 6
Dependent Claim
31 words
The structure of claim 3 wherein each coupling member has a transverse hole therein with a cord passing through the holes of the coupling members and being attached to the membrane.
Claim 7
Dependent Claim
24 words
The structure of claim 2 wherein a pair of couplings is employed at each intersection, said couplings being fastened together at a fixed angle.
Claim 8
Dependent Claim
31 words
The structure of claim 2 wherein said coupling members are attached to said membrane whereby said rods can be removed from said structure without detaching said coupling members from said membrane.
Claim 9
Dependent Claim
57 words
The structure of claim 1 wherein the couplings attaching the membrane to the poles have a clip attached to said membrane, said clip having a ring lying on the outer surface of the member and with a disc which lies under the membrane and is pushed into the ring to lock the ringed disc to the membrane.
