Definitions

  • This invention relates to a swimming pool in accordance with the pre-characterising part of the main claim.
  • swimming pools are known constructed of a flexible plastic material which deforms under the action of the hydrostatic pressure, typically polyvinyl chloride (hereinafter known as PVC) unsupported, ie without an internal fabric reinforcement layer. They comprise a side wall formed from one or more inflatable tubular elements.
  • PVC polyvinyl chloride
  • This first type of swimming pool has numerous drawbacks, first of which is the fact that the operations involved in its inflation are relatively lengthy and tiring. In addition, its repair is relatively difficult if one of the side wall tubes is damaged.
  • the lateral surface which has to withstand the water pressure comprises numerous lengthy weld lines connecting together the various constituent tubes of the side wall of the swimming pool and its base.
  • the swimming pool side wall consequently has a plurality of regions weakened by the welding, which have a pressure resistance less than the remaining parts of the wall and represent particularly critical regions especially in large-dimension swimming pools.
  • swimming pools constructed of flexible deformable plastic material comprising a base wall and side wall, both formed of said material, which are thermowelded together normally by high-frequency welding, and a lateral rigid support structure at the upper edge, to which the edge of said side wall is connected.
  • This second type of swimming pool also involves relatively lengthy and complicated assembly, as the different constituent parts of the lateral rigid support structure have to be connected carefully together and to members which fix them to each other.
  • the rigid structure of such swimming pools, when disassembled, is relatively bulky and heavy, resulting in problems both for its storage and for its marketing and distribution.
  • swimming pools comprising a base wall and an inflatable upper free rim, both constructed of a deformable plastic material, and a side wall thermowelded, normally by high-frequency welding, to the base and to the rim, but constructed of a flexible plastic material which is not deformed by the pressure exerted by the water, for example a supported PVC or a multi-layer structure comprising an inner layer of a fabric, for example polyester, on the two sides of which there is applied a sheet or layer of PVC, for example by calendering, by spreading or by adhesive.
  • the side wall of this third type of swimming pool is not cylindrical. Being constructed of a material which is not easily deformable but is also not sufficiently rigid it has to be of frusto-conical shape. with its major base at the bottom. This wall is divided into a plurality of panels welded transversely together, to the upper rim and to the base.
  • this third type of swimming pool requires the welding together of materials which are mutually different, this being relatively lengthy and complicated because it is difficult to automate and is therefore generally done manually.
  • swimming pools can only be used by filling them up to their upper rim, making it impossible to adjust the height of the water level.
  • swimming pools generally have a relatively tall side wall, they can only be used by adults and not by children.
  • An object of the present invention is to provide a swimming pool which obviates the drawbacks of the aforesaid swimming pools and in particular is of simple and fast construction, is of small bulk and weight when disassembled, and is of easy and rapid assembly.
  • a further object is to provide a swimming pool in which the water level can be adjusted and which can hence be used both by children and by adults.
  • a further object is to provide a swimming pool in which the side wall on which the water pressure acts has a greater resistance to this pressure.
  • a further object is to provide a swimming pool in which the side wall can be repaired and/or easily replaced, even if seriously damaged.
  • a further object is to provide a swimming pool which for equal characteristics is of lower cost and shorter construction time than similar swimming pools.
  • a swimming pool according to the invention comprises: a base wall 1, an inner side wall 2 having in correspondence with its free edge an inflatable tubular part 3, and an outer lateral support wall 4.
  • the inner wall 2 is a smooth wall, ie formed not from an assembly of superposed tubular elements but as a single wall.
  • the inner side wall 2 and the base wall are welded together along the lower edge of the side wall, the weld line being indicated by 5 in the figures.
  • the inner side wall 2 which is advantageously formed in a single piece, has a lateral weld line 6 which joins together the minor sides of the piece of plastic material from which this wall is constructed.
  • the inflatable tube 3 is formed in one piece with the wall 2 by folding a free end piece of the side wall into a tube, welding it to the wall itself and applying a conventional plug (not shown).
  • the outer wall is of frusto-conical shape and is constructed by laterally welding together a plurality of panels 4A of substantially isosceles trapezoidal shape (the lateral weld lines are shown dashed and indicated by 7 in Figure 1).
  • the inner side wall and base wall are constructed of a conventional flexible plastic material deformable under the action of the hydrostatic pressure, preferably unsupported PVC.
  • the outer side wall 4 is constructed of a conventional flexible plastic material which does not deform under the action of the hydrostatic pressure, preferably supported PVC.
  • the swimming pool according to the invention can be used with or without the outer support wall 4.
  • the swimming pool is shown used without the support wall.
  • the side wall bulges outwards by the action of the hydrostatic pressure (as shown in the figure) more or less according to the water level in the swimming pool.
  • the swimming pool can therefore be used even by very small children (who can easily enter the pool) as it is not of excessive height, this height being in any event adjustable by pouring more or less water into the swimming pool.
  • Figures 1 and 3 show a different manner of using the swimming pool.
  • the outer lateral support wall 4 is drawn over the inner side wall 2, the tube 3 is inflated and the pool is further filled until the water level reaches the tube 3 (as shown in Figure 3).
  • the swimming pool can be used by adults.
  • the swimming pool when not in use, can be completely folded up to present a very small bulk.
