Definitions

• the invention relates to the technical sector of swimming pool accessories, in particular the stairs equipping the executed swimming pools, either by means of independent prefabricated panels obtained by different processes, or by any other means perfectly known to a person skilled in the art.
• the invention relates to staircases of the type of those delimiting a scalloped front face from which the steps are formed as such.
• the face of the staircase provided with the notch has connecting wings, or other arrangements, to be fixed in continuity with the adjacent panels constituting the swimming pool basin.
• the notch has a general U-shape, while the stair treads can have a generally rounded shape in order to constitute a staircase known as the Roman staircase, or else any rectangular shape without thereby excluding d 'other forms.
• these staircases can be obtained by means of a manufacturing process by thermoforming as is apparent from the teaching of patent FR 2716406. It has also been proposed to produce this type of staircase by a rotational molding process as it emerges from the teaching of patent FR 2747417. Whatever their method of manufacture, these staircases are intended, as indicated, to be connected in continuity with the adjacent panels or other elements constituting the pool of the swimming pool and have arrangements for fixing a plasticized inner fabric known as name of "liner".
• the currently proposed manufacturing technique namely essentially thermoforming and rotational molding, requires specific added means allowing the liner to be fixed.
• this liner is carried out in combination with a seal and a fixing flange arranged in a rib formed peripherally at the notch of the staircase.
• the attachment as such of the liner, in combination with the seal and the flange, is carried out by means of screwing members or equivalent members. This is where important technical problems arise.
• the attached fixing shims must conform to such a shape so that it is necessary to use several independent elements. This need to bring a fixing support to allow the screwing of the assembly members has many disadvantages.
• the fixing of the shims is a long and delicate operation which must obviously be carried out in the workshop. It is first of all necessary to cut the various elements to the desired length and to adjust them correctly at the angles.
• the adjustment of the angles of the support elements can be carried out in a conventional manner, either by making a miter cut, or simply by placing the constituent elements in an adjacent manner and at 90 °. Whatever the solution chosen, there appears at the corner a gap resulting from the juxtaposed position of the fixing supports. It is therefore necessary to provide very precisely the positioning of the screw holes in order to prevent the assembly members from opening at these interstices.
• the object of the invention is to remedy these drawbacks in a simple, safe, efficient and rational manner.
• the problem which the invention proposes to solve is to no longer use wedges or other added elements for fixing the liner, in particular by means of screws or the like, without increasing the thickness of the staircase, but at the very least. on the contrary, with the aim of reducing such a thickness.
• a staircase for a swimming pool delimiting a scalloped front face from which the stair treads are formed, said face being shaped to be connected with adjacent or other panels.
• said staircase presents directly, at the time of its manufacture and overflowing from the internal side of the scalloped front face, at least one solid part capable of allowing, in its thickness, the engagement of fastening members of a liner.
• the fixing members can be directly screwed into the thickness of the solid part of the staircase, the thickness of which is determined to avoid the use of any added element or support.
• the solid part constitutes a rib acting as a wedge or support, obtained directly by a process of injection of a plastic material for the realization of the body of the staircase.
• the rib has a geometric U shape corresponding to that of the notch.
• the lateral edges of the rib are inclined in a convergent manner to allow demolding.
• the scalloped front face has a groove for mounting a seal for the watertight fixing of the liner in combination with a clamping flange by means of the fixing members engaged in the thickness of said rib.
• FIG. 1 is a perspective view of an embodiment of the staircase according to the features of the invention.
• FIG. 2 is a cross-sectional view taken along line 2.2 of Figure 1.
• Figure 3 is a cross-sectional view taken along line 3.3 of Figure 1.
• FIG. 4 is a cross-sectional view showing the attachment of the liner.
• the staircase is likely to have different geometric shapes.
• the staircase designated as a whole by (1) has a front face (la) defining a notch (lb) from which the steps (le) of the staircase are formed.
• the scalloped front face (la) is shaped to be connected in continuity, in an adjacent manner, with the panels constituting the swimming pool basin.
• the notch (lb) has a general U shape, the face (la) being of generally quadrangular shape and has two vertical branches (lai) joined by a lower horizontal branch (la2) thus constituting the edges of the notch (lb).
• the scalloped front face of the staircase has, overflowing from its internal side, a solid part (ld) capable of allowing, in its thickness, the engagement of fastening members (2) a liner (3).
• the solid part (ld) constitutes a rib whose thickness is determined to allow the fastening of the fixing members (2).
• This rib (ld) has a geometric shape corresponding to that of the notch (lb). In the example illustrated, the rib (ld) therefore has a general U-shape.
• This rib (ld) is obtained directly during the manufacture of the staircase which is obtained by a process of injection of a plastic material.
• the lateral edges (Idl) and (ld2) of the rib are inclined in a convergent manner to allow demolding.
• This zone can also be constituted by a plurality of spaced studs, arranged around the periphery defined by the geometric shape of the notch.
• the scalloped front face of the staircase has a groove (le) for mounting a joint (4) for the watertight fixing of the liner (3) in combination with a flange (5) by means of the fixing members (2) screwed into the thickness of the rib (ld) ( Figure 4).
• the various liner fixing arrangements, in combination with the rib (ld) are given for information only and are in no way limiting.
• Other equivalent means can be used with the objective of sealingly fixing the liner by means of members screwed into the rib (ld).
• the whole staircase (1) being obtained by injection of a plastic material, it is possible to also provide, at the time of the manufacture of the latter, internal reinforcement ribs. These provisions allow the thickness of the entire staircase to be reduced accordingly.
