SWIVEL COUPLING FOR A POOL CLEANER |
摘要 |
An improved swivel coupling (10) is provided for use with a pool cleaner (12 ), particularly for use in connecting a pool cleaner of the type powered by a suction or vacuum source to a flexible vacuum hose (16) which is connected i n turn to the suction side of conventional pool water filtration equipment (14 ). The swivel coupling (10) comprises outer and inner part-spherical ball segments (28, 30) adapted for respective connection to the vacuum hose (16) and to a water flow port on the pool cleaner (12), wherein the outer ball segment (28) defines a socket (32) for rotationally receiving and supporting the inner ball segment (30) in a manner to accommodate substantial angular a nd rotational swivel displacement therebetween. A plurality of generally axiall y extending ribs (46) are formed within the socket (32) for rotationally supporting the inner ball segment (30) with minimal contact area, and to define therebetween a plurality of axially elongated channels (48). The sock et (32) is also provided with a wiper seal (44).
