Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
216 words
A portable shelter comprising a frame assembly and a cover of flexible material supported on said frame assembly, said frame assembly including a central hub member, a plurality of inarticulate leg members rigidly mounted as cantilevers in said hub member to radiate horizontally therefrom and a rod member extending axially upward from said hub member, said leg members being arranged in pairs with the leg members of each pair being diametrically opposed to one another and each pair of mounted leg members together with the central hub member being bowed into a stressed inverted generally U-shape, said cover having an apex portion positioned above said hub member and a plurality of attachment means at locations remote from said hub member for securing the cover to said leg members to retain the latter in their bowed stressed positions, said apex portion projecting upwardly out of the surface of the remainder of the cover and defining an upwardly projecting central cone the tip of which is seated on the upper end of said rod member, said rod member being held in a state of compression between said tip and said hub member so as to distend said apex portion, and said leg members exerting outward thrust against the remainder of said cover so as to distend such remainder.

Dependent Claim
216 words
A portable shelter comprising a frame assembly and a cover of flexible material supported on said frame assembly, said frame assembly including a central hub member, a plurality of inarticulate leg members rigidly mounted as cantilevers in said hub member to radiate horizontally therefrom and a rod member extending axially upward from said hub member, said leg members being arranged in pairs with the leg members of each pair being diametrically opposed to one another and each pair of mounted leg members together with the central hub member being bowed into a stressed inverted generally U-shape, said cover having an apex portion positioned above said hub member and a plurality of attachment means at locations remote from said hub member for securing the cover to said leg members to retain the latter in their bowed stressed positions, said apex portion projecting upwardly out of the surface of the remainder of the cover and defining an upwardly projecting central cone the tip of which is seated on the upper end of said rod member, said rod member being held in a state of compression between said tip and said hub member so as to distend said apex portion, and said leg members exerting outward thrust against the remainder of said cover so as to distend such remainder.
Claim 3
Dependent Claim
61 words
A portable shelter according to claim 1, wherein said rod member is axially movable in said hub member to tension said cover between its tip and said attachment means when said rod member is elevated to an upper position, and locking means are provided between said rod member and said hub member to lock said rod member in said upper position.
Claim 4
Dependent Claim
33 words
A portable shelter according to claim 1, wherein said rod member has a pin projecting upward from its upper end, and the tip of said cover contains a grommet positioned on said pin.
Claim 5
Dependent Claim
18 words
A portable shelter according to claim 3, wherein said pin supports an ornamental bulbous element above said cover.
Claim 6
Dependent Claim
42 words
A portable shelter according to claim 1, wherein each of said leg members includes a generally horizontal portion turned downwardly at its outer extremity, and a generally upright portion forming a continuation of said horizontal portion at said downwardly turned outer extremity.
Claim 7
Dependent Claim
51 words
A portable shelter according to claim 5, wherein said cover has an imperforate portion overlying the generally horizontal portions of said leg members, and a strip portion adjacent each leg member extending from the imperforate portion downwardly to a point of attachment to the upright portion of the associated leg member.
Claim 8
Dependent Claim
20 words
A portable shelter according to claim 6, wherein said cover has screen-like material spanning adjacent ones of the strip portions.
Claim 9
Dependent Claim
35 words
A portable shelter according to claim 6, wherein said strip portions have apertures in their lower ends, and the leg members have pins extending from their lower ends through the apertures of the associated strips.
Claim 10
Dependent Claim
66 words
A portable shelter according to claim 8, wherein said strip portions have apertures in their upper ends, and the leg member associated with each strip portion extends through the aperture in the upper end thereof so that the upright portion of the leg member is on the external side of the strip portion and the horizontal portion of the leg member is beneath said imperforate portion.
Claim 11
Dependent Claim
54 words
A portable shelter according to claim 9, wherein each of said leg members is bowed in a state of compression between the lower end of its associated strip portion and said hub member to tension the cover and so that said rod member exerts an upward thrust on the apex portion of the cover.
Claim 12
Dependent Claim
23 words
A portable shelter according to claim 10, wherein the horizontal and upright portions of each leg member are tubular and are telescoped together.
Claim 13
Dependent Claim

A portable shelter according to claim 10, wherein the horizontal and upright portions of each leg member are tubular, and a rigidifying element is positioned in each said horizontal portion in the downwardly turned outer extremity thereof.
Claim 15
Dependent Claim
176 words
A portable shelter comprising a frame assembly and a cover of flexible material supported on said frame assembly, said frame assembly including a central hub member, a plurality of inarticulate bowed leg members connected as cantilevers to said hub member to radiate therefrom and terminating at their outer extremities in lower ends adapted to be carried on a supporting surface, and a rod member extending axially upward from said hub member, said cover having a plurality of attachment means secured to the lower ends of said leg members and a dome-shaped upper portion covering the upper portions of said leg members and a cone portion projecting axially out of the surface of the dome-shaped upper portion and overlying said hub member, said rod member engaging the tip of the cone portion, pairs of generally diametrically opposed leg members together with the interconnected hub member being bowed into a stressed inverted U-shape assembly so as to tension said dome-shaped upper portion and to urge the hub member and its rod member upwardly to tension said cone portion.
Claim 16
Dependent Claim
176 words
