the compression hoops from within the tent after insertion the compression hoops bear outwardly against the periphery of the tent to assure that it will maintain its configuration in an extremely stable manner when secured at the base perimeter or with guy lines the tension shelf compression hoop or hoops the external fabric and the center pole work together to create a stable wind resistant structure upward tension on the external fabric balances compression forces downward on the center pole and inwardly on the compression hoop or hoops working as a unit the structural elements create a tight wind resistant shell the tension forces on the fabric and tension shelf perfectly balance the compressive forces on the center pole and hoop the tension shelf balances with the section of exterior fabric above the compression hoop to keep the fabric taut lacking the tension shelf the compression hoop would have to be of much heavier and more rigid construction to withstand the pressure from wind and fabric while somewhat resembling an older center pole internal support umbrella type tent the tent of the present invention does not need the spreader bars attached to the center post or stays extending down from the apex it has the significant advantage that it may have full unobstructed standing room over.
