6 Claims. (Cl. 4—l72)
This invention relates to combination awning and swim

includes a horizontal leg '2 which is adapted to span a
swimming pool, preferably across the width thereof.

larger sizes of combined awning and swimming pool
covers, it is desirable to provide folding legs 27 at the
remote corners of the cover structure, as shown frag
