<p>The mobile, self-supporting sunshade for use on a beach, hard ground or grass land can be used by several persons for protection against sun burn. It provides an ideal central shade surface (23) which during the whole day when the sun is shining (14) can remain on the same ground area. The self-supporting construction enables it to be fixed simply with only two tension ropes (17) on loose ground. It does not have the customary central foot. It has an upper, elliptical protective sheet (1) with the two tension ropes (17) for fixture to the ground. The sheet has two compound fiber bars (3) and a variably adjustable ground tension rope (9). The sheet edges have a longitudinal seam (2) with double rings (16) and sand pockets (27).</p> |
