<p>CHALBERG-4 IMPROVED JET NOZZLE ASSEMBLY FOR THERAPY BATHS An adjustable nozzle assembly primarily for controlling the direction of a water-air jet of the type commonly found in whirlpool or therapy baths. The assembly comprises four components, namely, a pair of threaded flanged fittings, an eyeball shaped nozzle having a cylindrical channel therethrough, and a retaining ring for securing the eyeball nozzle in one of the threaded fittings. The two fittings are of cylindrical construction adapted to be concentric to each other. An outer fitting has threads along both the internal and external cylindrical wall thereof. The external thread is adapted to mate the outer fitting with a suitable source outlet pipe. The inner thread of one outer fitting is designed to mate with the corresponding outer thread on the inner fitting which tightens down concentrically therewith. The two fittings have overlapping annular flanges, the flange of the inner fitting being slightly larger than the flange of the outer fitting to provide a smooth continuous finished appearance when the assembly is fully installed through a suitable aperture in the wall of a tub. The aperture of the eyeball nozzle through which the water-air Jet exits is designed to terminate substantially in the plane of the inner fitting flange to avoid protrusions which would otherwise create a likelihood of injury to the user. The four components of the present invention are of unique but simple structure which may be manufactured from molded plastic and assembled together without the use of hardware.</p> |
