Abstract
Abstract A small, lightweight tent having enhanced comfort and stability includes a flexible covering having two generally similar side walls. Two resiliently flexible pole members are held flexed by the side walls so as to hold the side walls tense and thereby shape and support the tent. In this way, the tent is made freestanding. The tent further includes a flared top portion closed only by a net material to not only enhance ventilation of the tent, but also permit viewing of the sky.

Claim 1
Independent Claim
122 words
A portable shelter comprising a flexible covering having opposing side walls held tense to provide the shape of the shelter by two resiliently flexible pole members held in a flexed condition by peripheral portions of said side walls, each said pole member having the end portions thereof held respectively by front and rear peripheral portions of the same side wall to hold the pole member in an inverted generally U-shape tensing said side walls horizontally and the central portion thereof held by the upper peripheral portion of the other side wall to hold the pole member in a bowed shape tensing said other side wall vertically, said fabric covering further including a top wall interconnecting the upper portions of said side walls.
Claim 2
Dependent Claim
122 words
A portable shelter comprising a flexible covering having opposing side walls held tense to provide the shape of the shelter by two resiliently flexible pole members held in a flexed condition by peripheral portions of said side walls, each said pole member having the end portions thereof held respectively by front and rear peripheral portions of the same side wall to hold the pole member in an inverted generally U-shape tensing said side walls horizontally and the central portion thereof held by the upper peripheral portion of the other side wall to hold the pole member in a bowed shape tensing said other side wall vertically, said fabric covering further including a top wall interconnecting the upper portions of said side walls.
Claim 3
Dependent Claim
72 words
A shelter according to claim 1, said top wall being constituted by netting, said side walls each having a vertical contour which bows outwardly at the lower portions thereof and turns upwardly at its upper portions to form a flared portion, said shelter further including a door opening whereby said shelter may be readily ventilated by air currents flowing through said door opening and upwardly through the netting of said top wall.
Claim 4
Dependent Claim
