DETAILED DESCRIPTION OF THE INVENTION

(8) With reference in particular to FIG. 1, a generic water overflow edge device for swimming pools is shown, wholly indicated with reference numeral 10. The water overflow edge device 10 comprises, in a per se known manner, a channel 12 that substantially consists of a bottom wall 14, a rear wall 16 and a front wall 18 that is obtained with a plurality of modular structural elements 20 arranged in sequence and coupled together end-to-end. The channel 12 is also covered on top by a walking grid 50 that allows water of the swimming pool to enter into the channel 12 itself.

(9) According to the invention, with reference to figures from 2 to 6, each modular structural element 20 consists of a first component 22 in plastic material with structural function, provided at the bottom with coupling means 24 with the bottom wall 14 of the channel 12 and/or with the top of the vertical inner wall of the swimming pool. The structural component 22 is moreover provided at one side with a first surface 26, which forms the front wall 18 of the channel 12, and with a substantially vertical second surface 28, opposite the first surface 26 and configured to support a second coating component 30 in ceramic material, which forms the entire exposed surface of the water overflow edge device 10 and that has a finishing function.

(10) The structural component 22 is moreover provided, at the top, between the first surface 26 and the second surface 28, both with a substantially horizontal support portion 32, which is designed to support the walking grid 50, and with a substantially convex coupling portion 34, which is designed to be shape-coupled with a corresponding concave portion 36 of the coating component 30 in ceramic material.

(11) The coupling means 24 of the structural component 22 are preferably made up of a plurality of male-female couplers (FIG. 4), which are capable of being coupled together by interlocking and/or through gluing with adhesive materials along the upper edge of the swimming pool, so that the coating component 30 of each modular structural element 20 is aligned with the vertical inner wall of such a swimming pool. Between the male-female couplers 24 suitable clearances are made so as to allow channels 12 having profiles with a broken line to be laid, so as to closer approximate curved walls. For each modular structural element 20 there are standard lengths equal to 250 mm and 125 mm, so as to best approximate small bending radii in accordance with the market standards for tiles in the field of swimming pools.

(12) Preferably, the structural component 22 in plastic material is made in the form of a profile with an internally hollow continuous cross section. The structural component 22 can be, on the inside, provided with one or more reinforcing ribs 38 (FIG. 4), arranged longitudinally, and/or with one or more reinforcing dividers 40 (FIG. 3), arranged transversally and therefore perpendicular to such reinforcing ribs 38.

(13) The plastic material of the structural component 22 can advantageously consist of ABS (acronym of acrylonitrile-butadiene-styrene), or any other suitable thermoplastic polymer. The first surface 26 of the structural component 22 can advantageously be inclined according to an angle of over 90 with respect to the bottom wall 14 of the channel 12 so as to facilitate the outflow of water towards such a bottom wall 14.

(14) The coating component 30 in ceramic material is preferably made with a shape in section like an inverted J (FIG. 5), with a vertical front wall 42 exposed towards the inside of the swimming pool. The vertical front wall 42 has the concave portion 36 on top of it, which substantially has a C-shaped section and that is intended for hooking onto the structural component 22. The upper surface of the concave portion 36, which in the embodiment of the water overflow edge device 10 illustrated in the attached figures is configured to be substantially aligned with the walking grid 50, can advantageously be provided with a plurality of longitudinal grooves 44 with a finger-grip function for the swimmer. In another example embodiment of the water overflow edge device 10 the upper surface of the concave portion 36 could be configured so as to protrude upwards with respect to the plane defined by the walking grid 50. In such a way, for swimming pools in which, according to the standards, it is required, or in any case it is suitable, for there to be a so-called finger hold, the protrusion can define a finger grip for the swimmer who wishes to holding on to it or who needs to rest.

(15) During the installation of the water overflow edge device 10 each structural component 22 of the modular structural element 20 is laid on a suitable layer of adhesive material, pre-emptively applied at the peripheral edge of the swimming pool. Between the peripheral edge of the swimming pool and each structural component 22 shim layers can be possibly applied (not shown) for keeping such a structural component 22 at the correct level necessary for ensuring an effective overflow of water into the channel 12.

(16) The structural components 22 of the modular structural element 20, once they have been arranged side by side on the peripheral edge of the swimming pool, can be sealed to one another with suitable sealants, so as to ensure the hold of the entire front structure of the channel 12 and to prevent water from leaking in the two directions. As shown in FIG. 3, each structural component 22 can be provided with a second surface 28 finished with front grooves, as well as dovetailed male-female couplers 24, so as to ensure a suitable stick of the adhesive materials.

(17) In order to ensure that there is a stable coupling between the various structural components 22 arranged in sequence, on one of the transversal or top edges of each structural component 22 a protrusion 46 can be made (FIG. 3) that is configured so as to be inserted into a corresponding groove 48 (FIG. 6) made on the transversal or top edge opposite such a structural component 22. It is therefore possible to couple through interlocking, as well as by using glues and/or sealants, the various pairs of contiguous structural components 22.

(18) The coating component 30 in ceramic material, despite being specifically shaped in the manner described in the present description, is substantially similar in dimensions to a standard tile. The coating component 30 can indeed be made with lengths equal to 245 mm and 122 mm so that, by considering the average thicknesses of the gaps which are made during installation between coating components 30 adjacent to one another, it is possible to obtain the standard modularities of 250 mm and 125 mm described above. The gaps between adjacent coating components 30 can be filled with standard methods and systems of the field of laying tiles, like for example with epoxy mortars.

(19) In the joining step between each coating component and the respective structural component 22 below, which is typically obtained through gluing in addition to shape-coupling, it is possible to introduce a further layer of thickness (that is not shown) so as to reduce the tolerance of the overflow profile, which coincides with the upper surface of the concave portion 36 of each coating component 30. As shown in FIG. 6, the joining of modular structural elements 20 at angles with any width, below or above 90, can be carried out with the help of special angular components 52 which complete the upper walking profile of the water overflow edge device 10.

(20) It has thus been seen that the water overflow edge device for a swimming pool according to the present invention obtains the purposes that were previously highlighted. In terms of its appearance, the end result of the laying of a similar water overflow edge device is completely suitable, since the finishing of the exposed surfaces is actually obtained with materials in valuable ceramic. Also the part facing towards inside the channel, consisting of the visible rear surface of the structural components, has an acceptable appearance since it is hidden from the walking grid that closes the channel of the water overflow edge.

(21) It is worth underlining that the structural component of each modular structural element, suitably modified in its section, could be coated, on its front and top surfaces, with a mosaic coating component rather than in ceramic, with tiles having different sizes according to the requirement, typically 2020 mm. In such a way a different and potentially more valuable kind of finishing would be obtained for the water overflow edge device.

(22) The water overflow edge device for a swimming pool of the present invention thus conceived can in any case undergo numerous modifications and variants, all covered by the same inventive concept; moreover, all the details can be replaced by technically equivalent elements. In practice the materials used, as well as the shapes and sizes, may be any according to the technical requirements.

(23) The scope of protection of the invention is thus defined by the attached claims.
