Attorney, Agent or FirmAbstractA tent structure includes a covering which has four upright triangular walls laid out in rectilinear relation to each other. A pair of transverse ridges are formed at the top of the tent covering. A rigid ridge pole assembly supports the covering along one of the ridges; and a flexible spreader bar assembly supports the covering along the other ridge. Four top/corner pieces of covering material are provided--one for each quadrant defined by the cross ridges. Each top/corner piece extends between adjacent ridge sections and between the inclined edges of adjacent ones of the triangular walls to complete the enclosure. The spreader bar assembly overlies and is carried by the rigid ridge pole assembly; and the tent covering is tensioned by lengthening upright support poles which support the rigid ridge pole assembly. | |
