<p>COLLAPSIBLE SHELTER. A folding shelter is taught, which comprises a shell supported over a plurality of hoop-like frame members, and secured to a pair of base members of substantially the same configuration as the frame members. The base members are secured to a pair of framing plates, which overlap each other slightly and are hingedly connected to each other by a pin connection which is placed near the top of the overlap area of each. The centre-most of the hoop-like framing members is hingedly secured to both of the framing plates at the same pin that they are hinged to each other; and the remaining frame members are independently hingedly secured at their ends to one of the framing plates. The attachment of each of the other hoop-like frame members to the framing plates is such that each succeeding frame member away from the centre-most member is connected to the respective framing plate at a point lower and further away from the pin connection of the plates to each other than the last succeeding frame member.</p> |
