Abstract
Abstract A portable, suspended outdoor shelter includes a base panel having a pair of stiffening members secured in a pair of sleeves disposed along opposed longitudinally extending sides of the base panel. A pair of reinforcing web members extend along and reinforce the sleeves, and extend substantially therebeyond to be secured to a pair of spaced apart support structures such as adjacent tree trunks or boughs. A plurality of resilient, linear tubular members are bent in inverted U configuration and are secured above and between the stiffening members to apply tension laterally to said base panel. End panels extend between the ends of the base panel and the lower portions of their respective reinforcing web members, with a window and a door disposed in the end panels. A canopy extends between the upper edges of the end panels, and is supported by the inverted U tubular members. The base and end panels and canopy define an enclosed shelter which is suspended above the ground between two trees or the like, and is secure from the elements, and ground-dwelling creatures.

Claim 1
Independent Claim
104 words
A suspended, outdoor shelter, comprising a base panel having a pair of opposed, longitudinally extending edges; a pair of first sleeves formed in said base panel, each extending along one of said longitudinally extending edges; a pair of web members extending longitudinally, the medial portion of each secured to one of said edges of said base panel; a pair of longitudinally extending stiffening members, each secured in one of said first sleeves; means for urging said stiffening members outwardly each away from the other; and means for securing like ends of said web members to spaced apart support structures to suspend said shelter therebetween.
Claim 2
Dependent Claim
104 words
A suspended, outdoor shelter, comprising a base panel having a pair of opposed, longitudinally extending edges; a pair of first sleeves formed in said base panel, each extending along one of said longitudinally extending edges; a pair of web members extending longitudinally, the medial portion of each secured to one of said edges of said base panel; a pair of longitudinally extending stiffening members, each secured in one of said first sleeves; means for urging said stiffening members outwardly each away from the other; and means for securing like ends of said web members to spaced apart support structures to suspend said shelter therebetween.
