Abstract
Abstract A foldable shelter is disclosed which is suitable for personal use on a beach. The shelter includes a number of ribs which are pivotally connected together at their ends so as to enable adjustment or folding of the shelter. The joints are of novel construction and provide for ease of manufacture and more independent movement of the respective ribs.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
181 words
A foldable shelter comprising a framework having two joints, first, second and a plurality of intermediate ribs each of generally U-shaped configuration, a flexible cover connected to said ribs, one end of the cover being connected to the first rib and the other end of the cover being connected to the second rib, one of the free ends of each rib being connected at one of said joints and the other of the free ends of each rib being connected at the other of said joints, said joints permitting the ribs to be rotatable relative to one another, at least one of the joints including resilient means for resiliently restraining rotation of at least the first and second ribs relative to said joints, characterized in that the first and second ribs are mounted for rotation on a common shaft but are isolated from one another by an intermediate washer which is non-rotatably mounted on the shaft, thereby isolating rotational movement of the first and second ribs relative to said joints, so that said first and second ribs can be moved independently.
Claim 2
Dependent Claim
181 words
