A frame for a portable structure preferably in the form of a tent includes a hub having a plurality of tent pole frame members attached to it. The each tent pole is formed from a plurality of pole sections interconnected to one another along a structure permitting the pole sections to fold and/or compact upon one another. The poles define a proximate end attached to the hub and a distal end having a locking structure associated with it. The locking structure attaches each pole to the material defining the portable structure. The structure provides a reduced size package in the compacted position of the structure.

The tent support system of claim 1 wherein each tent pole has three stage sections, each of the three stage sections being telescopically associated with one another to permit the poles to define a first length in the extended position of the poles and a second length in the storage position of the poles, the second length being approximately one third of the first length. 3. The tent support system of claim 1 wherein each tent pole comprises three stage sections, one stage section being engaged with the hub and a second stage section defined by a telescoping pole extendable between a first stored position and a second extended positioned, the third pole stage section being joined between the first and second stage pole sections by a pair of knuckle mechanisms permitting folding of the second stage pole section on the third stage pole section and the second and third stage pole sections on the first stage pole section to define a storage position for the stage pole sections. 4. The tent support system of claim 1 wherein each tent pole comprises four stage sections, one stage section being engaged with the hub and a second stage section defined by a telescoping pole extendable between a first stored position and a second extended position, a third stage pole section attached to the second stage pole section by a mechanism locking the third stage pole section in position with respect to the second stage pole section in the extended position of the tent pole and preventing both clockwise and counterclockwise rotation in the extended position of the tent pole and adopted to permit release of and counterclockwise rotation of the second stage pole section with respect to the third stage pole section to define a storage position for the second stage pole section with respect to the third stage pole section. 5. The tent support system of claim 4 wherein the mechanism permitting counterclockwise rotation for storage comprises a first part adapted to receive an end of the second stage pole section and releasable locking the second stage pole section in an extended position to prevent further clockwise rotation of the second stage pole section during erecting of the frame structure but permits axial relative movement of the second stage pole section to permit counter clockwise rotation for storage. 6. The tent support system of claim 5 wherein each tent pole has four stage sections, each of the four stage sections being associated with one another to permit the poles to define a first length in the extended position of the poles and a second length in the storage position of the poles, the second length being approximately one fourth of the first length. 7. The tent support system of claim 6 wherein the tent pole is mounted for rotation to the walls of the legs along an axis of rotation positioned above the void. 8. The tent support system of claim 7 further including a separate rain fly attached to the tent poles. 9. The tent support system of claim 8 wherein the rain fly is generally rectangular and the flexible material is attached to the rain fly. 10. A portable structure support system including a frame structure, the frame structure having a stored position and an extended position, comprising: a hub having a central body having a vertical axis, the body having a plurality of legs extending outwardly and downwardly from the body, each leg comprising a first pair of opposed side walls, and a pair of opposed lips both horizontally and vertically spaced from one another with respect to the vertical axis, arranged to define a channel extending through the leg, the channel having a mouth sized to receive a supporting pole, and an enclosed exit void bounded and defined by the opposed side walls and the opposed lips and arranged to permit rotational movement of the supporting pole, the pole being captured between the opposed lips in an extended position of the poles so that a force on the supporting pole acts to lift the body of the hub, the supporting pole being mounted for rotation between the extended position along the captured position of the supporting pole between the opposed lips and storage position disengaged from the opposed lips;a plurality of supporting poles corresponding to an equal number of the plurality of legs of the hub, the supporting poles adapted to compact in the storage position to a reduced length less than half of their extended length, each supporting pole defining at least three stages, two of the stages joined by an assembly mechanism including an end piece attached to one stage and a connector body attached to the other stage, the interconnection between the end piece and the connector body being movable with respect to one another to define at least a first inserted fixed position and second rotational position such that in the inserted fixed position rotation of the associated tent pole stages with respect to the joint in either a clockwise or counterclockwise direction is prevented while in the second position only counterclockwise rotation is permitted, each pole also having a first end pivotally counted between the oppositely opposed side walls and adopted to be captured between the opposed lips in at least on position of rotation in which a second distal end of each pole is intended for engagement with the ground to provide a substantially self-erecting frame structure, the first end of each tent pole terminating with a surface adapted to engage one of the opposed lips of the hub in the erected position of the portable structure; anda flexible material associated with the supporting legs for defining the physical contours of the portable structure, the flexible material being attached to at least the hub and the distal end of the tent pole plurality. 11.
