ABSTRACT:
A collapsible sunshade for erecting on a sandy beach includes a polygonal sail member and a complement of supporting poles corresponding to the corners of the sail member, the poles being particularly flexible for maintaining a desired tension in the sail member without requiring accurate positioning of the poles in the sand. The poles each have a triangular trough-shaped blade member for securely anchoring in wet or dry sand with a low level of downwardly directed force being required for penetration of the poles into the sand. Loops extending from the corners of the sail member enclose respective shanks of the poles, tensioning of the loops providing frictional engagement with the shank members for supporting the vertical load of the sail member. The loops of the sail member can be adjusted up and down individually on the poles, the flexibility of the shank members assuring the required frictional engagement, even when the sunshade is exposed to winds and accidental contact. One or more sideshade members can be selectively positioned along the edges of the sail members for additional shading when the sun is low in the sky.
