Portable fabric shelter

Claim 2

A fabric shelter which is capable of being taken down, such as a roof, tent, or the like, said shelter comprising at least three assembled fabric roof panels which panels have in their upper part a seam line between adjoining roof panels along a curvilinear upper edge of each roof panel, which curvilinear edge is concave and relates to an upwardly-facing concave curvilinear seam line between adjoining roof panels, support posts adjacent outer ends of said edges and in supporting relation to the roof panels, and means for tensioning each of said roof panels, said means being fixed to a substantially rectiliner edge of the corresponding roof panel opposed to the seam line at two points which are spaced apart a distance which is less than a distance between said support posts in supporting relation to the corresponding panel.

Claim 3

A shelter as claimed in claim 1, wherein the curvilinear upper edge and the opposite edge of each panel are interconnected by small curved side edges.

Claim 4

A shelter as claimed in claim 1, wherein at least two adjoining roof panels are extended beyond the tensioning means to beyond the corresponding support post and a substantially triangular portion of fabric interconnects said at least two adjoining roof panels and constitutes a porch outside the corresponding support post.

Claim 5

A shelter as claimed in claim 1, 2 or 3, wherein the tensioning means are cables extending from the fabric.

Claim 6

A shelter as claimed in claim 1, comprising lateral walls which extend the roof panels between the fixing points of said tensioning means of a given panel, and other lateral walls interconnecting the first-mentioned lateral walls.

Claim 7

A shelter as claimed in claim 2, comprising lateral walls which extend the roof panels between the fixing points of said tensioning means of a given panel, and other lateral walls interconnecting the first-mentioned lateral walls.

Claim 8

A shelter as claimed in claim 3, comprising lateral walls which extend the roof panels between the fixing points of said tensioning means of a given panel, and other lateral walls interconnecting the first-mentioned lateral walls.

Claim 9

A shelter as claimed in claim 5, 6 or 7, comprising tensioning cables fixed to a junction between two adjacent lateral walls at a point intermediate between the roof panels and a ground on which the shelter is erected.

Claim 10

A shelter as claimed in claim 1, wherein each roof panel has a pair of said curvilinear upper edges relating to said seam lines connecting the two adjoining roof panels, all the pairs of upper edges of the roof panels being united at a centre apex.

Claim 11

A shelter as claimed in claim 9, comprising exterior means for holding the center apex in a raised position, which exterior means are under tension between said apex and the outer end point of each of the seam lines of the upper edges of the roof panels.

Claim 12

A shelter as claimed in claim 9, comprising inner means for holding the center apex in a raised position, which inner means are under tension between each of the outer end points of the upper edges of the roof panels and a plate carrying a vertical support post for the center apex.

Claim 13

A shelter as claimed in claim 5, 6 or 7, wherein the lateral walls all have a generally trapezoidal shape, the small base of the trapezoidal lateral walls extending the roof panels being substantially equal to the large base of said other lateral walls and being, like the large base, placed in the lower part of the shelter.

Claim 14

A shelter as claimed in claim 12, wherein the lateral sides of the lateral walls have in succession a rectilinear part and a curved part and are formed by isometric profiles in the flat state.

Claim 15

A shelter as claimed in claim 10 or 11, wherein the means for holding the center apex in a raised position are straps which are fixed to the fabric in the vicinity of said outer ends of said edges of the roof panels, extended beyond said roof panels and provided with an eyelet in hooking relation to the corresponding support post.

Claim 16

A shelter as claimed in claim 3, wherein said porch has an apex portion and said corresponding post has an enlarged curved convex head which fits in said apex portion of the porch.

Claim 17

A fabric shelter which is capable of being taken down, such as a roof, tent, or the like, said shelter comprising a plurality of assembled fabric roof panels which panels have in their upper part a seam line between adjoining roof panels along a curvilinear upper edge of each roof panel, which curvilinear edge is concave and relates to an upwardly facing concave curvilinear seam line between adjoining roof panels, support posts adjacent outer ends of said edges and in supporting relation to the roof panels, and means for tensioning each of said roof panels, said means being fixed to a substantially rectilinear edge of the corresponding roof panel opposed to the seam line at two points which are spaced apart a distance which is less than a distance between said support posts in supporting relation to the corresponding panel.

Claim 18

A fabric shelter which is capable of being taken down, such as a roof, tent, or the like, said shelter comprising a plurality of assembled fabric roof panels which panels have in their upper part a seam line between adjoining roof panels along a curvilinear upper edge of each roof panel, which curvilinear edge is concave and relates to an upwardly facing concave curvilinear seam line between adjoining roof panels, support posts adjacent outer ends of said edges and in supporting relation to the roof panels, and means for tensioning each of said roof panels, said means being fixed to a substantially rectilinear edge of the corresponding roof panel opposed to the seam line at two points which are spaced apart a distance which is less than a distance between said support posts in supporting relation to the corresponding panel.
