Abstract A self supporting collapsible tent structure having a tension bearing polygonal shaped floor member defining a first tent level, a plurality of hub members each carrying a plurality of sockets which are pivotal about axes which are co-planer and are interrelated one to the other as the sides of polygon, a series of said hub members disposed in a plane at a second tent level which is spaced apart from said first tent level and whose sockets are pivotal in a first direction, and additional series of said hub members disposed in a plane at a third tent level which is spaced apart from said second tent level and whose sockets are pivotal in a second direction, opposite to the said first direction, a single, apex forming hub member disposed at a fourth tent level and whose sockets are pivotal in said first direction, a first plurality of compression rods, the ends of which are seated in the said sockets of the hub members in slightly curved polygonal planes defined and bounded by the rod members and a second plurality of compression rods, one end of which are seated in sockets of the hub members at the second tent level and the other end of which are connected to the perimeter of the floor member.
A self supporting collapsible tent structure comprising: a planar tension bearing polygonal-shaped floor member having a defined perimeter and comprising a first tent level; a plurality of hub members each carrying a plurality of sockets which are pivotal about axes which are co-planer and which axes are interrelated one to the other as the sides of a polygon; a first series of said hub members disposed in a plane at a second tent level which is spaced apart from said first tent level and whose sockets are pivotal in a first direction; a second series of said hub members disposed in a plane at a third tent level which is spaced apart from said second tent level and whose sockets are pivotal in a second direction, opposite to the said first direction; an apex-forming hub member disposed at a fourth tent level which is spaced apart from said third tent level and whose sockets are pivotal in said first direction; a first plurality of compression rods, the ends of which are seated in the said sockets of the hub members, and which interconnect the hub members in polygonal planes defined and bounded by the rod members; and a second plurality of compression rods, one end of which are seated in sockets of the hub members at the second tent level and the other end of which are connected to the perimeter of the floor member.
