Leaf trap and main drain assembly

DETAILED DESCRIPTION It is a major object of the present invention to overcome the above set forth disadvantages of prior art swimming pool leaf trap arrangements.
The leaf trap and main drain assembly of the present invention includes a concave main drain which is recessed in a swimming pool floor with its upper end substantially flush with such floor.
The lower end of the main drain is formed with a drain opening.
An open-topped basket, having apertured bottom and side walls removably rests upon the main drain and is provided with an apertured cover removably connected to the basket.
The space between the bottom of the cover and the top of the basket defines a leaf-admitting entrance to the basket.
When leaves or other debris are forced into the basket, they are retained therein by the downward flow of swimming pool water through the main drain.
The cover is provided with a ring that is engaged by a swimming pool brush, or the like, to raise the basket to the surface.
During such upward movement leaves trapped in the basket are held therein by the downward force of water through the basket and cover created by such upward movement.
When the basket has been withdrawn from the pool, the cover may be removed from the basket to permit removal of leaves trapped therein.
It is important to note that an anti-vortex plate covers the main drain opening to prevent inadvertent contact of a swimmer or other object with the drain opening when the basket is not disposed within the main drain.
The cover of the basket extends only a short distance above the swimming pool floor so as to not interfere with movement of the hoses of an automatic swimming pool cleaner.
The cover also serves to prevent the entrance of such hoses to the basket to insure that the hoses won't blow leaves and other debris trapped therein out of the basket.
The basket is flush with the surface of the swimming pool floor so as to present an unobstructed path for leaves and other debris entering the basket.
The leaf trap and main drain assembly described herein is applicable to a wide variety of swimming pools, including gunite (concrete) pools, vinyl liner pools, and fiber glass constructed pools
