Shelter

A shelter including:

• a cover having substantially rectangular corner sections of fabric which is unstable on the bias,
• means for supporting the cover at the innermost corners of the corner sections,
• tensioning means,
• attachment means for attaching the tensioning means to the outermost corners of the corner sections to stretch such corner sections on the bias in a downward direction relative to the point or points at which the shelter cover is supported,
• a reinforced eye in said corner opposite said stretched corner sections,
• a central support pole for supporting the inner corners of the rectangular sections, said pole having means at the top which engages closely in said eye;
• and
• adjacent sections of the cover being joined along lines reinforced by strips of flexible material resistant to stretch extending from said reinforced eye to substantially the outer edge of said sections, said pole, reinforced eye and strips keeping the innermost corners and sides of the rectangular sections adjacent thereto relatively undeformed and linear while the outermost corners are stretched on the bias to stretch the outermost sides of the rectangular section so as deform the rectangular sections into a substantially offset diamond shape.
