DWpartemen Traduction Translation SDepartment 133178 00 31 07N The invention relates to the technical field of structural parts for swimming pools.

It is widely known that swimming pools can be built by using independent modular panels that are fitted together in various shapes to produce a swimming pool as such. In particular, the invention concerns panels of the type described in Patent EP 0382649, of which the present Applicant is also the holder. Each panel of a generally rectangular shape has a 'peripheral frame that delimits vertical wings for joining it to adjacent modular panels. Each modular panel has a relatively narrow width compared with its height. For information, the height of these modular panels is four times their width.

Advantageously, they are roughly 1.2 m high and roughly 25 cm wide.

In particular and as is apparent from claim 1 in above-mentioned Patent EP 0382649, the panel comprises a prefabricated structure and a reinforcing element having a cross-section designed to contain, over its entire height, concrete that is in contact with an anchorage, characterised in that: the structure and the reinforcing element are two independent elements which, after assembly, constitute said panel.

the prefabricated structure is of a generally quadrangular shape and has vertical wings which accommodate, in pairs, complementary fixing attachments which allow assembly with another juxtaposed structure.

the reinforcing element has a transverse cross-section capable of defining a vertical trough that opens out into a squared edge and said trough ~.ST Rpar( Sq Tra d Z'4/y De 033)7 Ddipartnement -f Traduction Translation P\ Department 2 A IrowJ bil.o J and said edge contain the concrete in combination with the anchorage.

the vertical trough is formed between two support and fixing wings situated in the same plane in order to ensure separate fixing of the reinforcing element between the wings of the structure, the width of the element, at the level of the wings, corresponding very substantially to the width between the inner faces of the wings the reinforcing element and the structure are made of reinforced concrete.

The various modular panels can be joined together by various means. For instance, the vertical wings of the frames have a plurality of oblong slots to accommodate assembly fittings after the elements have been placed side by side. It is clear that this solution is relatively timeconsuming, given the fact that the operator must fit each assembly fitting in the various slots and then tighten these assembly fittings.

In another embodiment, the wings may have, in pairs, fixing attachments of the tenon and mortise type that can be deformed by a heat source these too require external means.

In addition, after joining the various juxtaposed modular elements, it is necessary to ensure that the joints between the elements are leaktight, especially at the interstice produced by placing them side by side. This sealing operation is generally performed by applying a weld bead along all the separation gaps. Once again, these operations are time consuming and the result obtained is not always very satisfactory.

Spa ment i Tra tion VA 0>4' onC Ddpartement Traduction' I Translaton I SW Department -0 (33) o 30o71 3 on As stated, the outer face of these modular elements, i.e. that located on the same side as the peripheral assembly frame, can advantageously be fitted with an independent separately mounted reinforcing element that acts as a shaft. Once again, such provisions are clearly described and illustrated in the aforementioned patent.

Essentially, this type of element comprises a vertical trough the free end of which is terminated by a squared edge. After the modular panels have been fitted together, the squared edges are arranged in alignment and side by side in order to provide an upper anchorage for the pouring of concrete which is also poured into each of the vertical troughs in combination with reinforcement elements. This shaft can be fixed relative to the panels by bonding, welding or, if applicable, by means of separately mounted assembly fittings.

Given this state of the art, the problem which the invention aims to solve is to ensure instant assembly of the various modular elements without requiring the use of any separately mounted assembly fasteners with the aim of obtaining perfect sealing after assembly without resorting to any special, separate sealing operation.

Another problem which the invention aims to solve is to allow assembly of the reinforcing elements which act as a vertical shaft relative to the basic structure of the panels themselves, without the need for any means of assembling them in order to consequently achieve instantaneous, automatic locking.

In order to solve this problem:

In order to solve the problem of ensuring instantaneous assembly of the various panels with each other without the need to use separately mounted fittings for such assembly, the means of assembly consist of tongues which have a hooked retention area at their end, said tongues being distributed over the height of the wing and co-operating with matching through holes formed in the thickness of the other wing.

Advantageously, the head has an oblong shape and its width substantially matches the width of the widest part of the narrowed slot and is angled at relative to the latter, said head being physically attached to the centring part in the form of a pin of generally parallelepiped shape that cooperates with the width of the smallest narrowed part of said slot.

The invention is explained below in greater detail, reference being made to the following drawings in which: Figure 1 is a perspective view of a modular panel element and the shaft before assembly.

Figure 2 is a longitudinal sectional view of the panel.

Figure 3 is a transverse sectional view along line 3.3 in Figure 2.

Figure 4 shows how the panels are fitted together.

The reader is reminded that each panel is intended to produce, after assembly, a swimming pool (but not to the exclusion of other applications) and consists of an independent modular structure of generally rectangular shape. Each panel has a peripheral, stiffening assembly frame consisting of two vertical wings (la) and (Ib) and two horizontal wings (Ic) and The height of each element is substantially four times its width The basic design of this modular panel is 4i Tradu ion V Tr Ion Y> -L/l Dpartement y ft Traduction S Translation Department 1(3378 00 3107 6 Sthat of the type defined in aforementioned Patent EP 0382649.

According to one basic aspect of the invention, the vertical assembly wings (la) and (ib) have features capable of ensuring instant assembly of juxtaposed pairs of modular panels and simultaneous sealing of the resulting joint area. For this purpose, one (la) of the wings has, vertically over its entire height, a projecting profile (le) that has a lateral sealing lip This assembly and sealing element has a transverse cross-section that is substantially triangular and is intended to cooperate with a slit of matching shape (ig) over the entire height of the other wing The profile (le) and groove (ig) are close to the flat face (Ib) of the panel as such.

In addition, face (la) of each modular element has, over its entire height and at regular or irregular intervals, a series of fastening tongues (lj) capable of co-operating with through holes (Ik) formed in the thickness of the other wing (ib) in a corresponding manner. Each tongue (lj) has an area (ljl) for connection to the corresponding wing (la) and its end is the actual fastening area (1j2). All the tongues (lj) and slots (Ik) are located on the free end of the peripheral frame, i.e. that opposite the centring and sealing profiles and their corresponding groove (le) and (ig).

Note that when the modular panels are placed side by side, on wings (la) and (ib) of two adjacent panels, profiles (le) are engaged in grooves (ig) and sealing lip (if) is driven into said groove in order to ensure a perfect seal.

\<MER A 6 Dpartement' Traduction Translation Department 7 NThis position is secured by fitting fastening tongues (lj) into the matching openings It is also apparent that the vertical grooves (Ig) may allow several angular variations after joining the panels side by side, thus making it possible to obtain swimming pool structures having various geometrical shapes.

According to another aspect of the invention, the inner face of the panel (1h) has two vertical rows of studs (11) parallel and close to vertical wings (la) and (Ib) The stud systems (11) are intended to cooperate with narrowed slots (2a) in each of support wings (2b) and (2c) of the reinforcing elements that act as a shaft.

These elements in a well-known manner, consist of a squared upper edge (2d) and a vertical trough (2e) formed between support wings (2b) and (2c) Trough (2e) is intended to be filled with concrete, as is squared edge (2d) which, after joining the modular panels to each other, will constitute an anchorage.

The width of the shaft elements (2) substantially equals the width between the inner faces of assembly wings (la) and (Ib) of the basic modular element Each stud (11) has a head (111) and a centring part (112). The head (111) has an oblong shape the width of which substantially matches the width of the widest part of the narrowed slot (2a) and is angled at 900 relative to the latter. This head (111) is joined to centring part (112) in the form of a 0A Dipa ant 1,i Tradu tion V Dep 133)7 7 on. St

Note that, in order to prevent any inadvertent disassembly of the shaft relative to the panel, the latter may have, near at least one stud, a rib (In) that presses against a hump on part of the shaft element.

The basic modular element and the shaft element are made of any material, especially plastic, and may be produced by any known, appropriate manufacturing process, in particular, elements and can be produced by injection moulding.

The advantages are clearly apparent from the description, the following points in particular being underlined and emphasised: instant, immediate fixing of juxtaposed basic modular panels without the need to use any separately mounted assembly fittings making it possible, at the same time as assembly, to obtain a perfectly leaktight joint.
