Ring for surrounding a pool drain

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...

AI Technical Summary

Benefits of technology

[0008] It is another object of the present invention to provide a ring for positioning around a pool drain that provides a level surface for ensuring that a pool cleaner can ride on an intermediate portion of the ring and over the pool drain without being interrupted in the cleaning of the pool.

[0009] These and other objects are achieved by providing 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 that 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 without being interrupted in the cleaning of the pool.

Problems solved by technology

The antivortex of safety cover plate will typically extend upwardly from the bottom of the pool and causes an obstruction that may trap a pool cleaner and thus interrupt the cleaning of the pool.
