The invention also relates to a method of manufacturing such a panel, comprising the following steps: machining at least one housing in the body, placing in said at least one housing at least one first fixing means, possible closure of said at least one housing by means of a plug, disposed behind said at least one first fixing means, assembly of a fixing surface layer and an apparent surface layer, on either side of the body.

The invention will now be described in more detail with reference to particular embodiments given by way of illustration only and represented in the appended figures in which:

- Figure 1 is an exploded perspective view of a panel.

It goes without saying that the detailed description of the subject of the invention, given solely by way of illustration, does not in any way constitute a limitation, the technical equivalents also being included in the field of the present invention.

Referring to FIG. 1, a panel 1 comprises a fixing surface layer 2, a body 3 and an apparent surface layer 4. The body forms the main part of the volume of the panel 1. It is framed by two surface layers 2, 4. The fixing surface layer 2 is so called in that it is arranged on the side of the support on which the panel 1 is caused to be fixed and in that it is traversed by fixing means. The visible surface layer 4 is so called in that it remains visible when the panel 1 is mounted. This visible layer can thus have a wear and / or aesthetic function. According to the invention the panel 1 also comprises at least a first fixing means 5. This first fixing means 5 is inserted into the body 3 and is capable of allowing the panel 1 to be fixed. This fixing is carried out by means of at least a second homologous fixing means (not shown), capable of passing through the fixing surface layer 2, and if necessary a part of the body 3, to come fix with said at least one first fixing means 5.

To allow the insertion of said at least one first fixing means 5 into the body 3, the body 3 comprises at least one housing 8 capable of accommodating said at least one first fixing means 5.

According to one embodiment, a first fixing means 5 comprises at least one socket 6 able to cooperate with a homologous rod of a second fixing means.

Advantageously, a first fixing means 5 also comprises a bar 7 on which said at least one socket 6 is fixed. This fixing can be carried out by any means: welding, bonding, of material, etc. According to a preferred embodiment, this fixing is carried out by crimping. A bar 7 is advantageously pierced in line with each socket 6, in order to allow introduction, if necessary through, of a rod of a second fixing means. The function of a bar 7, in addition to bringing together several sockets 6 in order to facilitate their joint handling, is to allow an increase in the surface of the first fastening means 5, so as to increase its resistance to sinking into the body 3.

The fixing between a socket 6 of a first fixing means 5 and a homologous rod of a second fixing means can be carried out by any means: clipping, tight bore, screwing, etc. According to a preferred embodiment, a socket 6 and a homologous rod are threaded, in a complementary manner, so that they can be screwed into one another.

According to a first embodiment, said at least one housing 8 is shaped so that a first fastening means 5 received is flush with a surface layer 2, 4. For this, the shape and the depth of the housing 8 and the shape of the first fixing means 5 are such that the first fixing means 5 adapts perfectly with the housing 8. The surface layer is preferably the visible surface layer 4. Thus, a greater thickness of body 3 offers resistance to tearing of the first fixing means 5. The outcrop here allows continuity of the surface formed by the body 3 and / or a first fixing means 5 and arranged opposite the surface layer 2, 4 This continuity ensures a better aesthetic finish of the surface layer 2, 4 after its assembly with the body 3.

According to an alternative embodiment, said at least one housing 8 is shaped so that the first fastening means 5 received is not flush. In this case, the first fixing means 5 is disposed deeper in the body 3. Also there remains a space to the right of the first fixing means 5. In order to fill this space, the panel 1 also comprises at least one plug 9 shaped to close said at least one housing 8 behind a first fixing means 5 received. This plug 9 is such that it restores to the body 3 a continuous surface, flush with the facing surface layer 2, 4. For the same reasons as above, this surface layer is preferably the apparent surface layer 4. In addition, if a plug 9 is disposed on the side of the apparent surface 4, it is not crossed by the rod of the second means of fixing, and therefore advantageously does not have to be drilled.

Advantageously, a plug 9 is made of the same material as the body 3, in order to improve continuity.

It has been seen that the fixing surface 2 is intended to be crossed by at least one rod of the second fixing means in order to come and assemble with a socket 6. Also to facilitate this assembly, the fixing surface layer 2 is advantageously located in line with at least one socket 5, preferably in line with each socket 5. This makes it possible to facilitate drilling, from the fixing surface layer 2 and from the body 3 to the socket 5, during assembly. This marking is advantageously carried out during the manufacture of the panel 1 where the exact position of each socket 6 is known.

According to a preferred embodiment, to facilitate this assembly, the fixing surface layer 2 is advantageously pierced in line with at least one socket 5, preferably in line with each socket 5. This hole, advantageously passing through the surface layer of fixing 2 and partially the body 3 to the socket 5, facilitates the introduction of the rod during assembly. This drilling is advantageously carried out during the manufacture of the panel 1 where the exact position of each socket 6 is known.

The composition of panel in three parts : a body 3 surrounded by two layers of area 2, 4 allows to distribute the functions. The body 3 occupies a proportion important of 1'épaisseur of sign 1 better than 80%. The body 3 East advantageously realized in material lightweight selected among woods. there including cork and balsa. plastic. foam or nest bee. At opposite the layers of area 2, 4 occupeni t each a

low proportion of the thickness of the panel 1 less than 10%. The surface layers 2, 4 provide protection of the body by resisting penetration and crushing, as well as the rigidity and structural strength of the panel 1. One or both of them still provide an aesthetic function. and if necessary a wear resistance function. Also the surface layers 2, 4 are made of hard, rigid and resistant material.

According to an advantageous embodiment, a surface layer 2, 4 is made of a composite material comprising a thermosetting resin. In this case, it is possible to assemble the surface layer 2, 4 and the body 3, by means of the resin which is heated, for example by hot calendering, to allow said resin to adhere with the body 3.

The invention also relates to a method of manufacturing a panel 1 according to one of the preceding embodiments, comprising the following steps. During a first step, machining produces at least one housing 8 in the body 3. This at least one housing 8 allows the establishment of at least one first fixing means 5. If a first fixing means 5 is not flush, the corresponding housing is advantageously closed by means of a plug 9, arranged behind said at least one first fastening means 5. Next, a fastening surface layer 2 and an apparent surface layer 4 are assembled on either side of the body 3.
