Embodiment Construction

[0015] As illustrated in FIGS. 1-3, a ring 10 is provided for surrounding a pool drain 20 that is mounted over a drain in the bottom of a pool to act as an antivortex or safety cover plate to ensure that an individual is not injured as water is sucked from the pool for filtering the water. The ring 10 is designed to surround the pool drain 20 so that a pool cleaner, not illustrated, can easily traverse the pool drain 20 without interfering with the traversing movement of the pool cleaner.

[0016] A central portion 12 is provided for being positioned to surround a pool drain 20. The central portion 12 has a predetermined height and may be of any desired shaped. In a preferred embodiment of the invention, the shape of the central portion 12 may be circular.

[0017] An outer portion 14 is displaced a predetermined distance relative to the central portion 12. The outer portion 14 has substantially the same predetermined height as the central portion 12. In a preferred embodiment of the in...

Abstract

A ring for surrounding a pool drain to permit a pool cleaner to easily traverse the pool drain without interfering with the traversing movement of the pool cleaner includes a central portion positioned to surround a pool drain. The central portion has a predetermined height. An outer portion is displaced a predetermined distance relative to the central portion. The outer portion has substantially the same predetermined height as the central portion. An intermediate portion extends from the outer portion to the central portion. The intermediate portion provides a surface of substantially the same height as the central portion and the outer portion for enabling a pool cleaner to easily traverse a pool drain.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority under 35 USC 119(e) to U.S. Provisional Patent Application No. 60 / 609,263 filed on Sep. 14, 2004 the entire contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention is directed to a ring for surrounding a pool drain to permit a pool cleaner to easily traverse the pool drain without interfering with the traversing movement of the pool cleaner. [0004] 2. Description of Background Art [0005] Pool cleaners are utilized for automatically cleaning a residential or commercial pool by traversing the bottom and sometimes extending upwardly on the sidewalls of the pool to filter our impurities and debris from the pool. Conventional pool cleaners may be propelled by a jet of pressurized water or may be propelled by a mechanical drive mechanism to ensure that the pool cleaner is moved to traverse the bottom and / or side wal...
