Definitions

  • the shower unit is provided with a second, non-compressible, reservoir to replenish the main reservoir and allow a number of showers to be taken without the need to refill the system with water. It is preferred to spring bias the movable platform so that on removal of the weight therefrom,.the platform returns towards the starting position - preferably thereby drawing more water into the compressible reservoir from such a secondary reservoir.
  • FIG. 1 An embodiment of a shower system according to the invention is exemplified in Figures 1 and 2.
  • compressible reservoir I is filled with shower water.
  • the reservoir 1 is sealed by filler plug 2.
  • the water is retained by deformable lining 3 confined by rigid reservoir side wall portions 4, 5.
  • deformable lining 3 confined by rigid reservoir side wall portions 4, 5.
  • Compression of reservoir 1 may be achieved by standing (or placing a massive object) on movable platform 6, which is attached to walls 4.
  • Platform 6 is biased by springs 7 in such. a way that in its resting position the reservoir 1 is extended.
  • a pipe 10 having a plurality of non-return valves 11 connects the reservoir 1 to a spray head 12.
  • the system is primed before use by filling pipe 10 and spray head 12 with water using pump 13. Once the system is primed, a weight operating on platform 6 will cause
  • This invention relates to a weight-operated shower system which utilises the downwardly acting force of a massive body, e.g. a shower user. Operation of the system is passive since no exertion is required to maintain water flow.
  • the shower system of the present invention requires no external power source or pressurised water supply and is not driven by pressurised gas or stretched elasticated materials. It is simple and reliable in use, is inexpensive to manufacture and has the added advantage of being fully portable.
  • the apparatus comprises essentially a compressible reservoir connected to a pipe and spray head.
  • water is driven along the pipe and out of the spray head by the application of a downward force, e.g. the weight of a shower user, to a movable platform mounted over the compressible reservoir. Water is prevented from passing back into the reservoir by non-return valving in the pipe.
  • the compressible reservoir should be defined or contained by structure which prevents the reservoir from expanding, e.g. if the reservoir comprises an elastic bag, it should be confined by an inelastic surround.
  • a small priming pump for the pipe so that the pipe can be filled with water before the commencement of showering. a reduction in the confined volume of reservoir 1 and so will drive water out of spray head 12. Water will continue to flow so long as there is a weight on platform 6 and provided the reservoir has not reached the limit of its compressibility (i.e., maximum downward travel of platform 6).
  • FIG. 2 the reservoir 1 is shown substantially fully compressed. Walls 4 and.5 overlap and the deformable lining 3 has crumpled. A volume of water equal to the change in confined volume of reservoir 1 has been driven out of the spray head 12.
  • bias springs 7 return the reservoir to its original volume, thereby drawing water from secondary reservoir 15 past non-return valve 11 into the reservoir 1 to refill it.
  • the pipe 10 and spray head 12 may be self supporting (e. g. , in the form of a telescopic tube) or may be designed to be attached to structure supplied as part of the system or.may be hand .held or may be supportable by a structure on site (e.g., a pole, tree, caravan or building).
  • a structure on site e.g., a pole, tree, caravan or building.
  • reservoir Whilst one particular shape and design of reservoir has been illustrated, other configurations may be used within the scope of the invention provided the reservoir is compressible and is confined by an inelastic surround. Similarly, whilst the system has been referred to as a. shower system, it could equally well be operated in other modes - e.g. without the spray head to produce a water stream.
  • the platform and the shower base may each be provided with a tubular member, mutually slidable one into the other, upon which a coaxial biassing spring is mounted.
  • An arrangement of a . plurality of such members around the platform perimiter may improve the stability of the platform when the shower is in use.
  • the reservoir outlet may be placed above the lowest level of the reservoir so that, in use, some water is always retained in the reservoir when the platform has reached the point of maximum downward travel. This retained water mixes with refill water and thus acts as a safeguard against scalding if boiling water should be fed into the reservoir from the secondary reservoir.
  • a filter may be included in the shower head to prevent blockage of the shower rose by solid objects in the shower water.
  • a semi-rigid disc may be provided in the top of the reservoir lining, thereby holding the lining against the inner surface of the platform.
