Claim 1
Independent Claim
266 words
A rigid self supporting collapsible tent frame comprised of triangular roof and wall frame sections formed of elongate frame members hingedly interconnected at their ends to form a unitary structure in both the erected and collapsed state, the adjacent triangular roof frame sections of said collapsible tent having a common elongate roof frame member and alternate ones of the triangular wall frame sections having an elongate member common with a triangular roof frame section, said roof frame sections having a common apex in both the erected and collapsed state, the elongate members common to the wall and roof frame sections being hingedly connected at the ends thereof to define the ceiling area of the tent, said common wall and roof frame section members being comprised of at least two parts connected by means to provide a flexible joint that is spring loaded and allows both expansion and contraction at a point therealong remote from the points of connection of other roof frame section members connected thereto, the remaining alternate ones of the triangular wall frame sections having two common elongate frame members with the first mentioned alternate triangular wall frame sections and being inversely arranged relative thereto to define the base area and a plurality of free corners of the tent, the elongate frame members of the remaining alternate triangular wall frame sections defining the base area and the plurality of free corners of the tent being comprised by means to provide a flexible joint at an intermediate point therealong remote from the points of connection of the first mentioned alternate triangular wall frame sections thereto.
