FR2866044A1 - Swimming pool has impermeable inner liner pre-shaped to cover steps built into modular outer layer - Google Patents

Abstract

The swimming pool consists of an outer supporting layer constructed from assembled modular panels (1), at least one of which (2) is recessed and shaped to form the treads and risers of a set of steps (2b). The outer layer is fitted with an inner impermeable plastic liner (3) that is shaped during manufacture to have a part (3a) that fits exactly over the steps. The stepped module of the outer layer is made by an injection/compression process, and has an inner surface that is entirely smooth. In addition, the upper edges of the outer layer modules can be shaped to receive the edge of the liner, e.g. with a groove into which a liner edge bead can be clipped.

Description

2866044 1

  The invention relates to the technical sector of the construction of pool pools including those including a staircase to access the interior of the pool.

  A pool can be executed by means of prefabricated independent panels obtained by different methods, or by other means well known to a person skilled in the art. The staircase may be integrated over part of the length and / or width of one of the walls of the pool.

  More particularly, the invention relates to stairs of the type of those delimiting a notched front face from which the steps are formed as such. The notched front face generally has connecting flanges, or the like, to be fixed in continuity with the adjacent panels constituting the basin of the pool. For example, the notch may have a generally U-shaped, while stair steps may have a generally rounded shape to form a staircase known as the Romanesque staircase, without excluding other forms. This staircase can be obtained by thermoforming as shown in the teaching of FR 2,716,406 or by a rotational molding process (FR 2,747,417) or by a plastic injection method (FR 2,772. 410).

  To seal the basin, especially when it is made from assembled modular panels, the latter internally receives a plasticized waterproofing cloth known as a liner.

  2866044 2 However, the implementation of liner, especially when the basin has a staircase of the type described above, poses certain problems and requires significant credit.

  Indeed, the liner must be cut at the level of the indented part that presents the panel acting as stairs. In addition, this cut is made after laying the liner.

  Since the liner is placed by depression in order to press against the walls of the basin, it is first necessary to close the indented front of the staircase to ensure continuity at the level of the depression. This results in a large workforce and special know-how.

  In addition, the fact of having cut the liner at the indented opening, requires to ensure a fixation of the liner at this level.

  Generally, the fixing of this liner is performed in combination with a seal and a fixing flange disposed in a rib formed peripherally to the notch of the staircase. The attachment as such of the liner, in combination with the seal and the flange, is effected by means of screwing members or equivalent members. Again, the operation is difficult to perform and requires to achieve, at the level of the staircase panels, the rib for the establishment of assembly members.

  The object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.

  The problem to be solved by the invention is to facilitate the laying of the waterproofing fabric known as a liner, especially in the context of a swimming pool resulting from an assembly of solid modular panels and at least one panel delimiting a notched front face from which steps and counter steps are formed to form a staircase.

  To solve such a problem, the plasticized sealing cloth is shaped to match and marry the internal walls of said basin, said fabric having, directly during its manufacture, a portion adapted to marry the steps and counter-steps of the panel or panels ( x).

  Given these provisions, it is possible, after completion of the basin, that is to say assembly of the various panels together, including that or those constituting the stairs or to deposit, by depression, the liner directly in one operation.

  According to another characteristic, since it is no longer necessary to make a cut at the liner and ensure its attachment in a reported manner at the notch from which are formed the steps of the liner. staircase, the notched front is completely smooth.

  Advantageously, the panel acting staircase is obtained by the compression injection method. The steps and counter-steps are, for example, semicircular to form a staircase of the Roman type.

  2866044 4 To solve the problem posed to ensure the definitive fixing of the liner with respect to the entire pool of the pool, after the depression operation to perfectly flatten the liner against the walls of the pool, the edge upper panels, including that acting staircase, has a hooking profile of said liner.

  The invention is described below in more detail with the help of the figures of the accompanying drawings in which: - Figure 1 is a perspective view of an embodiment of a pool pool stairs according to the state prior art; FIG. 2 is a perspective view of the staircase shape illustrated in FIG. 1, according to the characteristics of the invention; - Figure 3 is a perspective view of an embodiment of a pool pool before the introduction of the liner; FIG. 4 is a perspective view corresponding to FIG. 3 after placement of the liner; - Figure 5 is, on a larger scale, a sectional view taken along the line 5-5 of Figure 4; - Figure 6 is, on a larger scale, a longitudinal sectional view considered to the right of the staircase.

  FIG. 3 in particular shows an exemplary embodiment of a pool basin resulting from an assembly of modular panels (1) and at least one panel (2) delimiting an indented front face (2a) from which are formed steps and counter-steps (2b) to constitute a staircase.

  2866044 5 The various panels (1) are assembled together and with the staircase panel (2) by any known and appropriate means. The panels (1) can be made by any known means. For example, they can be made according to the teaching of patent EP 0382649, which the applicant hereof also holds, or patent application FR 0307571 not yet published also belonging to the applicant, namely: by a method of compression injection of a plastic material The notched front face (2a) of the staircase is shaped to be connected in continuity, in an adjacent manner, with the panels constituting the basin of the pool. The indentation (2a) has a generally U-shaped shape. According to one feature at the base of the invention, the basin has a plasticized sealing cloth (3) known as a liner and shaped to match and conform to the walls. internal basin. More particularly, the fabric (3) has, directly during its manufacture, a portion (3a) adapted to marry the steps and counter-steps (2b) of the panel or panels (2). In other words, the portion (3a) is shaped to produce, during the manufacture of the liner (3) in the factory, steps and counter-steps (3b) corresponding to the steps and counter-steps (2b) of the staircase (2) (Figure 3).

  Given these characteristics, it is therefore possible to put the entire liner (3) inside the basin in a single operation by simple depression.

  2866044 6 In the same way as the different panels (1), the upper edge of the staircase panel (2) has, on the side of its internal face, a profiled groove (2c) for engagement and pinching of the liner (3) . Indeed, in a known manner, the end of the liner (3) has a ring or bead (3c) which can, therefore, be clipped into the profile section of the groove (2c).

  Given the characteristics of the invention, it appears that the indented front face (2a), from which are formed the steps and counter-steps (2b), is completely smooth (FIG. 2), in that it it is no longer necessary to make ribs for setting up the clamping and fixing means of the liner, as was the case according to the prior art (Figure 1). Advantageously, the entire staircase panel (2) is made by the injection-compression process from a plastic manner, especially recycled. The application of this process, known as such by the skilled person allows to obtain a panel of sufficient thickness and to avoid any deformation both in the vertical and horizontal plane.

  The advantages are apparent from the description, in particular it is emphasized and recalled the removal of delicate operations to achieve for the introduction of the liner at the staircase to significantly reduce costs, allowing to to obtain a perfect continuity and watertightness between the different panels, including that or those acting as stairs.
