Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
A knockdown portable shelter comprising: a frame including a centrally located connector and a plurality of supporting members, each having a rafter portion attached and extending radially outward from the connector, a vertically oriented pole portion, an arcuate portion curving downward from the rafter portion to the pole portion and forming a smooth transition joining the rafter portion and pole portion and a foot formed from a curved lower segment of the pole portion; a flexible canopy adapted to stretch over the rafter and arcuate portions of the supporting members and cooperating with those portions to enhance the structural rigidity of the frame; and means for securing the canopy to the frame; whereby the canopy is tensioned by the movement of the pole portions radially outward from the connector due to the weight of the rafter portions and the connector.
Claim 2
Dependent Claim
140 words
