Driven gears of the pool cleaner connector drive the steering device and cause rod ends engaging a pool side wall to lift and push the cleaner away from the side wall. The fitting and thus the rods are freely rotatable through a limited arc about an axis of rotation of the connector, defined by movement of a gear tooth between stop prongs. The ability of the rods to rotate freely within this arc overcomes a problem of excess drag to the cleaner by the steering device.Type: GrantFiled: April 15, 1998Date of Patent: April 27, 1999Inventors: Pavel Sebor, Brian H. Phillipson

Patent number: 5853030Abstract: A pipe coupling includes first and second coupling shells, each of which shells define a semicircular cross-section, and first and second longitudinal flanges, and wherein the shells are hingedly coupled together about the respective first longitudinal flanges. Fasteners secure together the second longitudinal flanges to enclose two longitudinally-spaced sections of pipe with a generally cylindrical housing. The first coupling shell further defines a port extending radially therefrom into which a grommet is preferably disposed. The grommet defines a normally-closed aperture for passing a needle therethrough for injecting a chemical, such as a disinfectant, into fluid, such as water, in the pipe.Type: GrantFiled: March 11, 1997Date of Patent: December 29, 1998Inventor: Larry Walding

Patent number: 5787538Abstract: This invention provides an accessory for an automatic pool cleaner, to increase the randomness of movement of a suction head of the pool cleaner, and a method therefor. The method comprises looping a section of the cleaner hose and allowing the hose sections leading up to the loop to vary in length. Particularly, the hose section leading from the pump to the loop is varied. The accessory comprises two connection parts, one for connection to each respective section of hose to form the necessary hose loop. Preferably one of the parts is slidable along the hose length to enable the hose to vary its length. The sliding action of the hose occurs between two stops in the length of the hose, and a pawl mechanism is provided to enable the slide to occur in one direction towards a stop. Contact with the stop causes the pawl mechanism to switch over and slide the hose in the opposite direction.Type: GrantFiled: July 3, 1996Date of Patent: August 4, 1998Assignee: Baracuda International CorporationInventors: Michael Edward Moore, Hendrikus Johannes Van der Meyden

Patent number: 5771934Abstract: A collar weight for securing hand held spray faucet hoses therethrough is provided, wherein the collar weight is made of a composition including a zinc-based alloy to replace the use of lead in the collar weight, to prevent leaching of lead from the collar weight. To maintain the hose in an untangled position beneath the surface of a sink, the collar weight is strategically placed along an arcuate surface of the hose to weigh down the hose at approximately the midpoint of the hose. The collar weight includes a top half collar portion and a lower half collar portion, which are joinable at respective inner edges thereof by fastening means, such as screws, to provide a generally hollow longitudinally extending bore for insertion of the hose therein.Type: GrantFiled: May 24, 1994Date of Patent: June 30, 1998Assignee: IW Industries, Inc.Inventor: Jerome Warshawsky

Patent number: 5749398Abstract: A flexible conduit which utilizes internal spacers and form wires to maintain dimensional integrity during contouring. Once formed into the desired configuration, the system can be made rigid by the injection of pressure into one or more internal elastomeric tubes which expand to solidify the structure. The "fixed" form can then be removed and measurements made for fabricating conforming production pipes and tubes.Type: GrantFiled: February 12, 1996Date of Patent: May 12, 1998Inventor: Goro Kambara

Patent number: 5743300Abstract: A flexible plastic water tube which can be stored on a roll has a flexible but substantially inextensible line member attached to it and can include a number of pre-attached drippers. The tube can be stretched between spaced apart supports with the line member preventing undesirable sagging. The tube can therefor be made from inexpensive thin walled plastic.Type: GrantFiled: January 13, 1997Date of Patent: April 28, 1998Assignee: PPI Corporation Pty. Ltd.Inventor: Paul Anthony McNeill

Patent number: 5733614Abstract: An arrangement for tightly enclosing a substrate with a heat-shrinking plastic sleeve (1), which has thickened sections (2, 3) along its longitudinal edges, has at least two rails (4, 5) pushed on the sleeve (1) after it has been placed around the substrate. The rails hold the longitudinal edges of the sleeve (1) together before, during and after the heat-shrinking. The two rails (4, 5) form a junction area and S-shaped profiles (6, 7) are placed in the junction area on both sides of the thickened edge sections (2, 3) and are enclosed by both of the rails (4, 5).Type: GrantFiled: August 23, 1996Date of Patent: March 31, 1998Assignee: Alcatel Kabel AG & Co.Inventor: Werner Stieb
