Other features, details and advantages of the invention will be better understood on reading the additional description 30 which will follow in connection with drawings in which: FIG. 1 represents an exploded view of an embodiment of the plate According to the invention with the various components, FIG. 2 shows in perspective the body of the stage according to the invention without the magnetic means; FIG. 3 represents a sectional view of the body of the stage passing through a means of 4a-4c respectively show a view of the front face, the top and the rear face of the fixing plate according to the invention, - Figure 5 shows in perspective the assembled plate 5 according to the invention, FIG. 6 represents a sectional view of the plate according to the invention passing through a cap, FIG. 7 shows a front view of the plate according to the invention provided with a frame, FIG. view of the face of the plate according to the invention provided with a bubble level, - Figure 9 shows a sectional view through the bar of a lighting means assembled with the body according to the invention, 15 - Figure 10 is a perspective view of a lighting means partially assembled with the body according to the invention; FIG. 11 is a perspective view of the energy store partially assembled with the body according to the invention; FIG. 12 represents a front view of the energy reserve according to the invention, FIG. 13 represents a perspective view of the energy reserve according to the invention, and FIG. 14 represents a perspective view. rear view with apparent edges of the body assembled with the plate and partially depicted illumination means according to the invention; - FIG. 15 is a perspective view of another embodiment of the body of the stage, FIG. represents a front view FIG. 17 shows a sectional view AA of FIG. 16, FIG. 18 shows a view of the rear face of the body of the stage according to FIG. 15. 19 represents a view from above of the body of the plate according to FIG. 15 FIG. 20 represents a perspective view of another embodiment of the plate, FIG. the plate according to FIG. 20, - FIG. 22 represents a sectional view CC of FIG. 21, - FIG. 23 represents a view of the rear face of the plate according to FIG. 20, and - FIG. 24 represents a view of FIG. above the plate 10 according to Figure 20. As explained above, the plate according to the invention allows to receive a frame and fix it on a support, a wall for example, without special intervention. The board itself can be made of any material, wood, metal, alloy, plastic, composite, or the like. In plastic material, the plate is made for example by molding or rotational molding. According to the invention, there is provided one or more magnetic means whose function is to maintain the frame in the horizontal position and retaining means prohibiting any vertical displacement of descent of the frame. These two means ensure in combination the perfect positioning of the frame on the plate. One or more magnetic means are thus part of the plate and the frame has one or more complementary magnetic or ferromagnetic means cooperating with those of the plate. According to the invention, the adoption of retaining means makes it possible to provide either a magnetic retaining means or two magnetic retaining means. Indeed, the one or more magnetic means can not assure him or them alone (s) the maintenance in place of the frame. This is why the applicant has planned to combine the maintenance in position of the frame and its physical restraint by means of restraint. This combination offers the advantage of a great simplicity of realization while allowing the reception of large mass frames. This structure avoids the use of magnets too powerful whose magnetic field can be disruptive for the entourage.

Of course, the plate is fixed to the support for example by gluing by providing a double-sided tape or with fixing screws. In FIG. 1, there is shown an exploded view of an embodiment of a receiving plate 1 consisting mainly of a solid body 2 and a fixing plate 3 to the wall. The body 2 is of generally parallelepipedal shape, comprises different machining operations and a cage 8 in the form of a U. The cage 8 houses and holds in place magnets 4 and 5 between which a spacer 6 is interposed. This makes it possible to have two zones of magnetization and thus to facilitate the horizontal fixing of the frame 50 as will be explained later. The free end of each branch 9, 10 of the U is extended respectively by lugs 11 and 12 parallel to the base of the U itself parallel to the bottom 13 of the body 2, thus defining an open space, each of the branches 9, 10 being respectively provided with longitudinal grooves 14, 15 opening outwards. In the fixing position, the groove 14 is oriented downwards and the groove 15 upwards. It goes without saying that the bottom 13 of the U is parallel to the rear face of the body 2 and that the branches 9 and 10 of the U and the grooves 14 and 15 are parallel to each other. During assembly, two caps 7a and 7b for holding the respective magnets 4 and 5 make it possible to close the cage 8 by wedging the magnets 4 and 5 against the spacer 6. Each cap 7a or 7b comprises a wall 71 provided with an extension 72 intended to engage in the U of the body 1. The holding means are constituted here by the magnets 4 and 5. It can be seen that each magnet 4, 5 is machined by milling at the intersection of two of its walls to define, at each end, two bases 41 and 42 intended to engage in the U of the body 2 by being retained 35 by the legs 11 and 12. These two magnets 4 and 5 are separated by the U-shaped spacer 6 for engaging in the U of the body 2 and being held there by the lugs 11 and 12. In Figure 2, there is shown in perspective the body 2 alone. The body 2 is provided with through-lights 16 and 17, openings 18, 19 and 20 and a blind hole 21. The usefulness of these elements will be explained later. The body 2 is provided with two lugs 22 and 23 spaced from each other and projecting from the branch 9 of the U, on which the frame 50 will be supported as will be explained below. These two lugs 22 and 23 can be joined together to form a continuous support. The body 2 is also provided with grooves 48 and 49 arranged perpendicularly to the groove 15, and whose role will be explained later. Similar grooves (not shown here) are provided in the opposite groove 14. In FIG. 3, there is shown a side sectional view passing through a retaining means of the body 2 alone, highlighting the U-shape of the profile. mentioned above with the bottom 13 and the branches 9 and 10, the position of the lugs 11 and 12, and that of the lug 23. FIGS. 4a-4c illustrate the embodiment of the fixing plate 3.

As can be seen in FIG. 4a showing a front view of the plate 3, this plate 3 is generally parallelepipedal and comprises two arms 31 and 32 intended to cooperate with the through-holes 16 and 17 of the body 2. The plate 3 is also provided with holes 35 and 36 positioned in correspondence with the holes 18 and 19 respectively when the plate 3 is connected to the body 2, in particular to possibly pass fixing screws on the support. The plate 3 is also provided with two indentations 37a and 37b in its upper part and two indentations 37c and 37d in its lower part and whose role will be explained later. Finally, a through-hole 59 is seen at the center of the plate 3, this hole 59 making it possible in particular to pass a screw there to more strongly secure the plate 3 to the body 2 by means of the bore 20 whose position corresponds to that of the through hole 59 FIG. 4b is a view from above of the fixing plate 3, highlighting the arms 31 and 32 and the claws 34 and 33. These two arms 31 and 32 are terminated by claws 33 and 34 intended to hang on. on the body 2 opening into the lights 16 and 17. The plate 3 also comprises two longitudinal ribs 44 and 45 whose role will be explained later. It can also be seen that this plate is provided with an overmoulding 3a intended to complete the positioning of the plate 3 on the body 2. FIG. 4c is a rear view of the fixing plate 3, highlighting the two ribs 44 and 45 which extend respectively from the notch 37a to the notch 37c and the notch 37b to the notch 37d. Figure 5 shows the plate 1 equipped with its components. The spacer 8 has been introduced into the stand 8 first, then on each side the magnets 4 and 5 and finally each cap 7a, 7b. The magnets 4 and 5 are wedged inside the U thanks to the caps 7a and 7b and separated by the spacer 6. It can be seen that the claws 33 and 34 respectively at the ends of the arms 31 and 32 of the plate 3 passing through the body lights 16 and 17 hold body 2 and plate 3 assembled by clipping. Figure 6 shows a sectional view of the plate 1 passing through one of the caps, for example 7b. It can be seen that the overmolding 3a of the plate 3 abuts in the body 2 preventing any relative displacement of this plate relative to the body. Figure 7 shows a front view of the plate 1 provided with the horizontal amount of a frame 50. Magnetic means 52 and 53 shown in dashed lines are provided in this frame. The frame 50 will thus be held vertically 30 by the lugs 22 and 23 on which it bears and is held horizontally by the magnets 4 and 5. The frame 50 can be detached easily, for example by acting slightly at one of the its ends upwards, thus disconnecting the magnets 4, 5 of the complementary magnetic means 35 and 52 of the frame 50, and then substantially pulling the frame 50 upwards to remove the lugs 22 and 23 of the plate 1. On can easily change the strength of the magnets 4 and 5 according to the frame 50 that is to be fixed to the plate 1 according to the mass of said frame. FIG. 8 represents a front view of the plate 1 provided with a level bubble 51 located in the blind hole 21. The bubble level 51 makes it possible to control the horizontal placement of the plate 1 during its installation on its support. We see the position of the plate 6, magnets 4 and 5 and caps 7a and 7b. The claws 31 and 32 of the arms 31 and 32 applied to the body 2 are also seen. FIG. 9 represents a sectional view illustrating a lighting means 38 of the frame fixed on the plate 2. This means 38 comprises an arm 39a extended. at its free end illumination 39b and has at its other end 40 a male portion 46. As seen in the figure, the lighting means 38 is engaged via the male portion 46 in the groove 15 of the body 2 following a dovetail connection. Figure 10 shows a perspective view of the lighting means 38 partially assembled with the body 2. The male portion 46 is partially engaged in the groove5 and simply continue the movement to fully secure the lighting means and the plate. FIG. 11 shows a reserve of electrical energy 47 partially assembled with the body 2 and intended to supply the lighting means 38. This energy reserve 47 is provided with a male part 43 intended to cooperate with the groove 14 of the body 2. Figure 12 shows a front view of a power reserve 47 and Figure 13 a perspective view of the energy reserve 47. It goes without saying that the two grooves 14 and 15 may be identical and therefore that the positions of a power reserve 47 and a lighting means 38 can be interchanged if necessary. Figure 14 shows a rear perspective view of the body 2 equipped with the illuminating means 38 partially shown. To supply the lighting means, two connectors 54 and 55 are provided in the form of plates respectively disposed in the ribs 44 and 45 of the body 2. These connectors 54 and 55 also pass through the respective grooves 48 and 49 ( arranged perpendicular to the groove 15), and by the respective grooves not shown (arranged perpendicularly to the groove 14). The connectors arranged in the grooves 48 and 49 and in the grooves not shown are in correspondence respectively with the contact pads (located on the male portion 46) of the lighting means 38 and the contact pads (located on the male part 43). ) of the energy reserve 47. These connectors 54 and 55 thus make the electrical connection between the energy reserve 47 and the lighting means 38. The energy reserve 47, whose male portion 43 is inserted into the groove 14, supplies the lighting means 38, whose male part is inserted into the groove 15, via the connectors 54 and 55.

FIG. 15 is a perspective view of an alternative embodiment of the body 2. In this embodiment, two separate housings 80a and 80b are provided at a distance from one another, each intended to receive a magnetic means, in particular a magnet, which will be fixed to the body 2 in particular by means of an adhesive or clips. The grooves 15 and 14 are located respectively in the upper part and the lower part of the body 2. The other machining operations do not differ from the embodiment of the body 2 presented in the preceding figures, in particular the blind hole 21, the openings 18 and 19 , the through-lights 16 and 17, and the pins 22 and 23. It is seen here that the housings 80a and 80b are in the extension of the holes 18 and 19, which optionally allows the magnets to be glued forward of the fixing screws passing by the openings 18 and 19. The grooves 48a and 49a arranged perpendicular to the groove 15 are identical to the grooves 48 and 49 of the body 2, shown in Figure 2. Figure 16 is a front view of the body 2 of the plate 1 according to Figure 15. It is seen that the openings 18 and 19 partially occupy the bottom of housing 80a and 80b. The housings 80a and 80b are of parallelepipedal shape and the holes of cylindrical shape. Finally, there are four reliefs 100a to 100h inside each housing 80a and 80b. The shape of the magnets (not shown here) is adapted to that of the housings 80a and 80b and thus comprise complementary grooves of these reliefs 100a to 100h which serve to guide and maintain the magnets introduced into the housing 80a and 80b. Figure 17 is a sectional view through the reliefs 100a and 100b of the housing 80a, the body 2 according to Figure 16. The lugs 22 and 23 are not visible in this view because of the position of the section.

FIG. 18 shows a view of the rear face of the body 2 of the plate 1 according to FIG. 15. The openings 18, 19 and 20 and the lights 16 and 17 are visible. The grooves 48a and 49a are visible as well as the grooves 48b and 49b arranged perpendicularly to the groove 14, for example 6 mm wide, and make it possible to have electrical connectors as seen in the first embodiment. 19 shows a top view of the body 2 of the plate 1 according to Figure 15, showing the lugs 22 and 23 projecting from the body and located at the base of the housing 80a and 80b. The lugs 22 and 23 are here separate and at a distance from each other. 20 shows a perspective view of another embodiment of the plate 1. This is in a generally parallelepipedal general shape and provided with three housings 90a, 90b and 91, the lateral housings 90a and 90b being near each end and the housing 91 being disposed between the two housings 90a and 90b.

This embodiment can be used in two different ways. For example, a magnet can be placed by gluing or by close fitting, in particular, in each of the lateral housings 90a, 90b and thus fixing the frame 50 (not shown) horizontally by means of these two magnetic means 35. It is also possible to place by gluing or by fitting a magnet in the central housing 91 and thus fix the frame 50 by this single magnetic means. In both cases, the lugs 22 and 23, in the vicinity of the housings 90a and 90b serve as vertical supports to the frame retained by the magnetic means. The plate 1 is here as a single block and is fixed to the support including using a permanent adhesive or possibly reusable. This allows a great simplicity of use of the plate 1. Figure 21 shows a front view of the plate 1 according to Figure 20 showing the housing and the lugs. The lateral housings 90a and 90b and central 91 also each comprise four reliefs 100a-1001 identical to those of the previous embodiment. There is no blind hole 21 but a piercing 101 through the plate 1, and used to house a bubble level. Figure 22 shows a sectional view along CC of Figure 21 through the pin 22. The reliefs 100a and 100b are visible in the housing 90a. FIG. 23 represents a view of the rear face of the body of the plate 1 according to FIG. 20. It is also seen the digging 101 passing through the plate 1. This rear face is intended to be fixed directly to the support, in particular by gluing, to level of the surface 101 delimited by dashed lines. Figure 24 shows a top view of the body of the plate according to Figure 20. This view highlights the lugs 22 and 23 projecting from the plate 1. It is seen that the upper face of the plate has no groove. It is the same with its underside. It goes without saying that the strength of the magnet or magnets is adapted to the characteristics of the board.
