DESCRIPTION:
BRIEF SUMMARY
This invention relates to an improved spa pool which can be easily and readily constructed for domestic use, and also which offers greater comfort to the user.
BACKGROUND OF THE INVENTION
Many people are enthusiastic about the benefits to be gained by the use of a spa. The relaxing effect of water and air surging over the body surfaces, has a very relaxing effect, and many people with back problems testify to the relief they obtain after spending some time in a heated spa.
Almost invariably there is mention of a side effect, i.e. the subsequent discomfort experienced from spending extended periods spent lying or sitting on or against the hard surfaces of the spa vessel itself.
Spas are usually constructed of concrete, with or without internal tiling, fiberglass, plastics materials such as acrylic resins, timber, and the like.
Thus it is an object of the invention to provide a spa which has a soft interior for greater comfort to the user.
It is a further object of the invention to provide a spa with a plastic membrane lining which has a cushioning substance between the plastic membrane and the actual structure of the spa including the floor of the spa.
In a preferred form of the invention the cushioning substance can be a foam material similar to that used for upholstery in household and office furniture. In most cases this material is multi-cellular, similar to plastic sponges, but it is preferable to use a uni-cellular material, e.g., a material which has individual air cells unconnected one to the other.
Thus the invention provides an interior surface which is comfortable to lie or sit in with none of the discomforts which may prevail with a hard interior.
Also it is an object of the invention to provide an insulated spa to thus minimise heating costs in the operation of the spa.
BRIEF STATEMENT OF THE INVENTION
Thus there is provided according to the invention a spa in which the body of the spa is constructed of a solid material, the water in the spa being retained by a liner or membrane, characterised in that there is provided between the liner and the solid material a resilient material selected from foam plastic material or foam rubber so that the spa has a soft interior for greater comfort of the user.
Preferably the body of the spa itself can be constructed of metal which is suitable treated to withstand any corrosion should it be installed in the ground. Alternatively other materials such as fiberglass, acrylic resins or timber may be used. No floor structure is required because the lining of the spa will rest on the foam padding which is placed on the floor during assembly.
In all cases there preferably will be a locking system fitted to the wall to hold the membrane in place. This should also provide for simple removal of the lining in the event of a damage being experienced to the lining requiring the liner to be replaced.
It is preferred that the fittings such as spa jets, suction points, and skimmer unit which are installed in the spa wall be designed to enable the lining to be replaced without having to disturb the main fittings themselves which will obviate the necessity of having to disturb the pipework on the exterior of the spa wall.
