<p>A cover for a swimming pool comprises an awning of flexible waterproof sheet material having guide members secured to its longitudinal edges. A pair of side rails are fixed to the longitudinally-extending walls of the pool. The rails are of keyhole cross-section so that the guide members at the edges of the awning can slide into the side rails from their ends and slide longitudinally of the rails to secure the edges of the awning to the walls of the pool along their entire length. A shaft is mounted in a storage box formed adjacent one transverse edge of the pool so that the awning can be rolled around it for storage. Guidelines are attached to the leading edge of the awning and are joined to form a pull-line which runs back to a drum in the storage box. The drum and shaft are driven by means of an electric motor to move the awning along the pool.</p> |
