Abstract: A 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.

Abstract: A backpack permits the wearer to adjust the shoulder straps, backband, and waistband to his individual needs or desires. An integral molded plastic frame is specially contoured to avoid restrictions of motion on the person wearing it. The frame is provided with a number of slots which permit attachment of the sack and adjustment of the locations at which the shoulder straps, backband and waistband or belt are attached. The shoulder straps include loops of material which fit through the slot and are held in the desired position by a specially designed removable fastener. The waistband may also be sized to the individual wearer's requirements by selectively adding or removing one of a plurality of pads which are threaded onto the belt for comfort.
