Abstract
Abstract An inflatable tent structure comprising a plurality of pneumatically interconnected, elongate inflatable tubes defining the perimeter of the tent structure for being inflated in unison. A valve is provided for inflating the tubes and a plurality of wall panels are suspended from and between the tubes to define the enclosure of the tent whereby the tubes define a support structure exterior to the enclosure of the tent. The tubes define a dome-shaped structure, the tubes converging in pneumatic interconnection with each other in a single plane at the apex of the dome-shaped structure. The valve includes a manifold into which all of the tubes interconnect at the apex of the dome-shaped structure.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
An inflatable tent structure comprising: (a) a plurality of pneumatically interconnected, elongate inflatable tubes positioned in spaced-apart relation around the perimeter of the tent structure for being inflated in unison, said tubes defining a dome-shaped structure terminating at an apex, said tubes converging in pneumatic interconnection with each other in a single plane at the apex of the dome-shaped structure; (b) valve means for inflating the tubes and comprising a manifold into which all of the tubes interconnect at the apex of the dome-shaped structure; and (c) a plurality of wall panels suspended from and between adjacent tubes to define an enclosure of the tent whereby the tubes define a support structure exterior to the enclosure of the tent; wherein said tubes include an interiorly projecting flange to which said wall panels are attached in spaced-apart relation.
Claim 2
Dependent Claim
137 words
An inflatable tent structure comprising: (a) a plurality of pneumatically interconnected, elongate inflatable tubes positioned in spaced-apart relation around the perimeter of the tent structure for being inflated in unison, said tubes defining a dome-shaped structure terminating at an apex, said tubes converging in pneumatic interconnection with each other in a single plane at the apex of the dome-shaped structure; (b) valve means for inflating the tubes and comprising a manifold into which all of the tubes interconnect at the apex of the dome-shaped structure; and (c) a plurality of wall panels suspended from and between adjacent tubes to define an enclosure of the tent whereby the tubes define a support structure exterior to the enclosure of the tent; wherein said tubes include an interiorly projecting flange to which said wall panels are attached in spaced-apart relation.
Claim 3
Dependent Claim
108 words
An inflatable tent structure comprising: (a) a plurality of elongate inflatable tubes positioned in spaced-apart relation around the perimeter of the tent structure for being inflated, said tubes defining a dome-shaped structure terminating at an apex, said tubes converging in a single plane at the apex of the dome-shaped structure; (b) valve means for inflating the tubes; (c) a plurality of wall panels suspended from and between adjacent tubes to define an enclosure of the tent whereby the tubes define a support structure exterior to the enclosure of the tent; wherein said tubes include an interiorly projecting flange to which said wall panels are attached in spaced-apart relation.
Claim 4
Dependent Claim
108 words
An inflatable tent structure comprising: (a) a plurality of elongate inflatable tubes positioned in spaced-apart relation around the perimeter of the tent structure for being inflated, said tubes defining a dome-shaped structure terminating at an apex, said tubes converging in a single plane at the apex of the dome-shaped structure; (b) valve means for inflating the tubes; (c) a plurality of wall panels suspended from and between adjacent tubes to define an enclosure of the tent whereby the tubes define a support structure exterior to the enclosure of the tent; wherein said tubes include an interiorly projecting flange to which said wall panels are attached in spaced-apart relation.
Claim 5
Dependent Claim
36 words
An inflatable tent structure according to claim 1 or 2, wherein said flange is integrally formed from material from which the tubes are formed by joining adjacent material together along a predetermined length and width thereof.
Claim 6
Dependent Claim
41 words
An inflatable tent structure according to claim 1 or 2, wherein said tubes define a saw horse-like structure with two pairs of downwardly diverging legs interconnected by a single top support for defining a tent which is substantially triangular in cross-section.
Claim 7
Dependent Claim
23 words
An inflatable tent structure according to claim 4, wherein said valve means includes a manifold into which respective pairs of the legs interconnect.
Claim 8
Dependent Claim
21 words
An inflatable tent structure according to claim 5, wherein said valve means comprises a valve for interconnection with an air pump.
Claim 9
Dependent Claim
26 words
An inflatable tent structure according to claim 4, wherein aid tubes include an interiorly projecting flange to which said wall panels are attached in spaced-apart relation.
Claim 10
Dependent Claim
34 words
An inflatable tent structure according to claim 7, wherein said flange is integrally formed from material from which the tubes are formed by joining adjacent material together along a predetermined length and width thereof.
