Each panel 110, 120, 130, 140 adopts a parallelepipedal shape and are joined by their horizontal edges coming in opposite relation. A panel 120 is preformed with a recess 121 to accommodate a handle 122.

As illustrated in the drawing of Figure 2, the door P forms a single vertical panel whose vertical faces are divided by three horizontal bands formed by the sides of the devices D in the assembled position.

The drawings: Figures 3 and 4 illustrate the assembly between the panels 130 and 140 but could illustrate indifferemmejat the assembly between the panels 110 and 120 or entered the panels 120 and 130. The songs 141 and 132 panheaux 140 and 130 are consisting of horizontally flat surfacings between which the device D interposes.

As illustrated, each device D has four main parts namely, two identical profiled assembly parts 200 and 300 and two identical corners 400 (only one of which appears in the drawings of FIGS. 3 and 4 but which appear in pairs in the drawing of FIG. figure 1). According to a preferred embodiment, these assembly parts are made of aluminum.

The assembly part 200 is fixed on the upper edge 132 of the panel 130 and the assembly part 300 is fixed on the

Bottom edge 141 of the panel 140 - the assembly parts; then, assembled together.

As illustrated, the connecting pieces 200 and 300 are preformed to assemble together by being head-to-tail when assembling the elements. In this arrangement, the profile has complementary shapes which, once assembled, form an assembly ensuring the positiQnnenœnt and the assembly of panels between them.

Indeed, the assembly parts are each preformed with projecting profiles and recessed profiles of suitable shape to accommodate said protruding profiles to form transverse retaining surfaces. Once the profiled pieces of assembly fixed on the songs, the panels; can be joined together: by a combination and a sliding longitudinal translation or horizontal transverse profiled assembly parts. The corners 400 are then inserted; in strength; the two extr-emltés to maintain in position the assembled assembly.

An embodiment of preforming the parts forming the device. e.st decl't ei: -d. in the drawings of FIGS. 5 and 6.

Only the piece 200 is described but the piece 300 has the same profile and is simply arranged head to tail to form the assembly.

This piece 200 is a linear profiled piece of aluminum.

His profile illustrated by the drawing; of FIG. 5 adopts :: a vertical plane side 210 which will be positioned coplanar with the vertical planes of the panels and in particular with that of the panel 130 on which the piece 200: is fixed? a horizontal flat bottom face 220 which will be positioned on the horizontal plane edge 132 of the panel 300 and has a common edge with the vertical plane side 210 and a common edge with the second side 230, a second side 230 preformed with a inclined surface coming to join projecting outside 1;;: - a surface pla: ne horizonta: the 240 intermediate returning vecs the interior of the room 200 on eUvircn; two-thirds of the width <3e the workpiece 200 and positioned at a height corresponding to half the thickness of the side 210, - a nui-ulle inclined surface 250 parallel to that forming the side 230 and coming to join a flat horizontal top face 260 disposed at the same height as that of the side 210.

The angle formed between the plane surfaces and the inclined surfaces is forty-five degrees.

Thus, the projecting angle formed by the 230 side foritie a male portion capable of cooperating with the re-entrant angle formed by the surface: 250. Likewise, the recessed angle between the side 230 and the edge forms a female part capable of co-operating with the projecting corner by the surface with the surface. :;: 2: 6O-it is understood that during assembly, an identical piece arranged, 'head-to-tail' such as the, · ρΐβ00;: 300 ,, a :, times: their: flat affixed hiizcntâlê intermediate ( 240 for the piece 200) in contact, will see its own inclined surfaces come into contact with the inclined surfaces of the piece 200 to create a transverse retainer both horizontally and vertically.

In order to maintain these surfaces in contact and ensure a fixation between the assembly parts 200 and 300 and therefore between the panels 130 and 140. Dn corner 400 is interposed in force between the intermediate plane surfaces of the two assembly parts 200 and 300 positioned one in the other.

In order to facilitate its insertion and to optimize the jamming which it implements, the intermediate planar surface 240 is advantageously preformed in the middle part of a groove 241 with a U-section, and only when assembled to an identical pin positioned head -bêche, the two grooves are positioned vis-à-yis to form a mortise rectangular section in which the corners 400 are inserted forced.

As illustrated in the drawing of Figure 3, to ensure that jamming and close · both ends, said corners 400 adopt the form of a párâllélépipède two of the vertical edges at the same end are chamfered.

It also appears that the use of a half-thickness on one side of the assembly part allows the assembly of the two assembly parts not to have a thickness greater than the thickness of a single piece of assembly. 'assembly.

As illustrated in the drawing of: the figiire Sj. the assembly part 200 is. In addition, a pair of holes 270 are provided at intervals between the holes: The holes are used for the screw: Assembly parts:. the song of the panel, augue ·! they, associate themselves. These holes are made at the bottom of the wall, so that the heads of the screws can not be removed. if they are placed in a position relative to a piece of equipment. the other. For reasons, one hole on two is used: in order to avoid that the heads of screws are not retro-fitted, they are not coaxial. . -608 oa..Features ·, pe.rraettent: to obtain a very thin assembly.

As illustrated · 8: αΕ drawing .de. 9, in order to guarantee a good screwing and a good position of the screw, the devices of the invention comprise: a screwing jig 600 which : punctually s'asier · to the profile of '"as: sembla, ge 200 above: de3,:; holes 270 crossed, nt ·. of fixatiott · 3 ·: 3 · '· .3η'Γ'θ: ·'. ·, '0η:: guiding the screw V, a good, positioning. des'.dîtè'.â.

According to an illustrated feature, said plate 610 is further preformed with a downward tubular projection cooperating with the hole 270 to coax the Greuse core of the tube 620 with the hole axis 270. The jig 600 and the screw V are then removed, and the screw V is reintroduced into the hole started to fix the assembly part 200.

Finally, as illustrated in the drawing of Figure 6, the groove 241 is further preformed by at least one light 280 which comes opposite a corresponding eoEante 380 light in the section 300. Gette light 280 welcomes a key 281 providing the role of mechanical bütée. Projecting in the lumen 380, this mechanical stop prevents the longitudinal translation movement of the assembly part 300 relative to the assembly part 200 and consequently prevents the equivalent movement between the associated panels.

As illustrated in the drawing of FIG. 7, the sections of panels 110, 120, 130, 140 form, once disassociated and arranged face-to-face, a reduced parallelepipedal telescope which will define the volume of reception of a suitcase 500 which It also hosts the other components of the system that are needed for the community. (parts of the wall, corners, keys).

It will be understood that the mechanical ventilation device and the ready-to-assemble door, which have just been described and shown above, have been intended for disclosure rather than limitation. Of course, various arrangements, modifications and improvements may be made to the example above, without departing from the scope of 1'invention.
