end of sleeve 16 as better seen in fig6 the end of sleeve 16 may be stitched closed and folded over so as to be releasably secured to a corner of tent 10 by means of releasable fasteners such as the button snap 60 illustrated the above described inflatable supports may thus exhibit an important characteristic namely that when inflation begins as air flow reaches the ends of the supports the result is an uplifting since the ends are sealed and air pressure is introduced and since the bottom part of the sleeve is secured to the tent floor at the very end the sleeve as it begins to inflate begins to push against the pegged tent floor as seen in fig6 a and by so pushing urges the inflatable support upwardly so as to assist in self erecting of the tent the more air pressure is added the more force u201c f u201d helps the tent to self erect further the greater the maximum air pressure the greater the rigidity of the tent structure since the design of the rubber bladder is made so that the end of the supports become stronger with more pressure the uppermost limit of the air pressure that the inflatable support will sustain is primarily only limited by the tensile strength of the sleeve material rather.
