Definitions

  • This invention relates to a hydrotherapy nozzle in particular for use with hydrotherapy baths or pools of the Jacuzzi type.
  • Hydrotherapy baths, pools or tubs have one or more nozzles positioned below the water line in which air and water are mixed and forced into the bath producing a jet of foaming water which is said to give a therapeutic effect for persons bathing therein.
  • This method of operation is relatively time consuming and invariably involves a considerable degree of mesa since the sealant becomes spread about the bath surface during the second fixing of the nozzles necessitating a considerable amount of cleaning up after the system has been fitted.
  • the invention seeks to provide an improved form of nozzle in which the above disadvantages can be reduced or eliminated.
  • a hydrotherapy nozzle comprising a main body and jet outlet, a chamber therein in which water and air may be mixed, an inlet and outlet, and a threaded portion for cooperating with a correspondingly threaded member for clamping the nozzle to the bath wall characterised in that there is a recess about the threaded portion and a bore connecting the recess with the back of the nozzle.
  • the recess carries a sealing member, such as an O-ring, which bears against the bath wall when the correspondingly threaded member is tightened into the nozzle.
  • the bore may preferably be employed to inject sealant into the recess when the nozzle is assembled in place.
  • a hydrotherapy nozzle generally designated 10, for example in general similar to that described in our published patent specification No. 2147523, comprises a main body 12 within which is a chamber 14 for mixing air and water.
  • the chamber 14 has water inlet and outlets 16, 18 as well as an air supply 20 communicating therewith.
  • the nozzle 10 is held in place on a wall 22 of a bath having a hole 24 cut therein by means of an internally threaded portion 26 extending into the chamber 14 which is engaged by a correspondingly threaded member in the form of a bezel 28 which locates on the inside of the bath and has an externally threaded portion 29 which protrudes through the hole 24 to engage the threads 26.
  • annular recess 30 is provided circumscribing the threaded portion 26.
  • a bore or port 32 connects the recess 30 to the back face of the nozzle 10.
  • a O ring 34 is also located in the recess 30.
  • holes 24 may be cut in the bath walls 22 as before and the nozzle positioned and retained in place by tightening the bezel 28.
  • the hoses connecting the inlets and outlets 16, 18 of adjacent nozzles (as well as the air supply tubing) may be measured cut to size and connected up with the nozzles in place about the bath.
  • Final sealing in accordance with the invention, is accomplished by slackening off each of the bezels 28 a small amount, for example one turn, and injecting sealant through the port 32 into the recess 30.
  • the nozzle body 12 is moulded from a transparent plastics material and, where this is the case, the injected sealant can be visually checked to ensure that it completely circumscribes the threaded portion 26 filling the recess 30.
  • the bezel may then be retightened completing the fixing of each nozzle. But in any event and in the case of a non-transparent plastic nozzle body, the sealant will be seen to exude from the periphary of the 0-ring seal thus indicating that the recess is full.
  • the bezel may then be retightened completing the fixing of each nozzle.
  • the nozzle of the invention may be used with the system described in our above mentioned published patent specification but is not, of course, so limited since it may be employed with advantage in other systems where sealing requires to be effected by the use of a mastic sealant and it is desired to avoid disassembly and excessive amounts of sealant spreading over adjacent surfaces.
  • the rear of the nozzle is easily accessible and the sealant can be injected from the tapered nozzle of a mastic gun which forces the sealant through the port 32 and into the recess 30 under sufficient pressure to ensure that it reaches all parts of the recess and provide an effective seal.
  • the base 36 of the "V" formed by inlet 16 and outlet 18 is provided with a drain port 38 connecting with a drain pipe 40.
  • a valve either in the port 38 or elsewhere in the pipe 40, is opened to allow all the water to drain away.
  • a secondary passage 42 may be provided so as to allow any water trapped in the chamber 14 to drain also.
  • the pipe 40 may be part of a network draining several nozzles 10.
  • the passage 32 in this embodiment has a different circumferential location so as not to interfer with the port 38 and pipe 40, and is not therefore seen in this sectional view.
  • the passage 42 can be serviced if and when necessary to clear it of any sediment, lint, or the like by means of a flexible rod passed in through the bezel 28 from the bath side.
