Abstract:
An improved motor-driven pump is provided for delivering a flow of water in a swimming pool or spa environment or the like. The improved pump includes a motor mounted within a motor housing having a seal plate mounted at one end thereof. The seal plate carries a shaft bearing for rotatably supporting a drive shaft having an outboard end connected to an impeller disposed within a pump chamber defined cooperatively by the seal plate and a volute housing mounted thereon. A primary seal assembly includes an axially spring-loaded dynamic seal ring carried on the drive shaft for rotation therewith and for running engagement with a stationary bushing carried by the seal plate. A secondary seal assembly is positioned axially between the primary seal assembly and motor bearing, and includes at least one slinger disk for radially outwardly slinging any water leaking past the primary seal assembly through a vent chamber.
Abstract:
The specification and drawings describe and show one embodiment in the form of a sparkle light bulb (10) with a plurality of different colored LED bulbs (12) controlled by a circuit (16) that selectively operates the LED bulbs in color wash mode or color dance mode. The controller circuit also has memory for further selectively locking the LED bulbs in a desired color pattern. The sparkle light housing (24) has guides (40, 48) for aligning and guiding the lamp bulb into a multi-pin recptacle.
Abstract:
Automatic swimming pool cleaners are detailed. The cleaners may employ filter bags (18) with novel stiffeners (78) to help retain their optimal debris- collection shapes in use. They additionally may include bags made of material having sanitizing properties or additives, allowing water sanitization to occur as water flows through the bags themselves. Cleaners described herein further may include discs (26) having generally radial but non-linear slits to facilitate navigation in particular conditions and fix buoyant material (90) within a collar (70) by which a bag is attached to a body of the device.
Abstract:
A hose clasp (10) includes a generaly split collar (38) having seperable free ends (40) including a pair of radially outwardly extending clasp arm (42, 44). The clasp arms (42, 44) are notched to accommodate movement to an interlocked crossover position, with a boss clasp arms (42, 44). The clasp arms (42, 44) protruding through a lock port (58) in the other clasp arm (42, 44).
Abstract:
A fiber optic light system for illumination use in a swimming pool or spa environment or the like. The light system includes a light source unit positioned at a suitable dry site for delivering a relatively intense light signal to the input end of one or more optical fibers, wherein this light source unit may include a color wheel for controllably varying the color of said light signal. A support manifold includes a retainer disk for substantially aligning the input ends of the optical fibers with the light signal for optimizing light input thereto. The output ends of the optical fibers are captured within a sealed lens assembly mounted at a submerged or underwater location such as within a pool or spa wall. This lens assembly includes multiple lens segments for distributing the light in a controlled manner within the swimming pool or spa.
Abstract:
A magnetic control valve is provided in a suction powered pool cleaner (10) of the type for vacuuming dirt and debris from submerged floor and side wall surfaces of a swimming pool. The pool cleaner comprises a head defining a suction inlet (34) for vacuum inflow of water and debris into a plenum chamber (40), and further through a suction tube (42) adapted for connection via a vacuum hose (14) to a conventional pool water filtration system (12). The control valve includes an oscillatory valve member (64) movable between open and substantially closed positions relative to an upstream end of the suction tube to produce pressure fluctuations causing the cleaner to advance in steps over submerged pool surfaces. Oscillatory driving of the valve head is assisted by permanent magnets (74, 76, 78) mounted on the valve member and cleaner head to generate repulsion forces as the valve head respectively approaches the open and closed positions.
Abstract:
An improved disposable filter bag for use with a pool cleaner of the type disclosed, for example, in U.S. Patents 5,863,425; 4,558,479; and 3,822,754. The filter bag is formed from a porous filter material such as a non-woven spunbond polymer having marginal seams formed by direct welding, in the absence of additional adhesive material, to form a reinforced cuff defining an open bag mouth leading to a hollow bag interior. The cuff is configured for removable attachment to a downstream end of a pool cleaner suction mast, as by removable connection to a mounting collar as disclosed in U.S. Patents 5,863,425; D409,341; D468,067; and 6,740,233. The filter bag incorporates a ported tab formed generally at an upper end thereof for facilitated removable coupling to a pool cleaner supply hose or the like which supports the filter bag in a generally upright orientation.
Abstract:
A filter bag for a pool cleaning device includes a bag structure, formed of nylon mesh material, and a discharge opening, formed by a zipper. The zipper allows for temporary access to the interior chamber of the bag by opening the zipper.
Abstract:
A bag clip (12) is provided for removably mounting a filter bag (14) onto a suction mast (20) of a pool cleaner (10) to collect and retain debris vacuumed by the pool cleaner (10) from submerged floor and side wall surfaces of a swimming pool. The bag clip (12) includes an inner support collar (32) for reception into an open mouth of a porous filter bag (14), in combination with an outer clamp ring for releasibly clamping the bag mouth onto the inner support collar (32). The bag clip additionally includes quick release latch tabs (46) for snap fit mounting onto the pool cleaner suction mast (20). In use, the outer clamp ring can be quickly and easily opened to permit filter bag (14) removal and disposal of collected debris, followed by re-installation of the same or a replacement filter bag (14).
