Description

Title of the invention: MODULAR ISOLATION BOOTH Technical field of the invention

[0001] The invention relates to a modular isolation booth, in particular for professional premises, public spaces, and private spaces. Technical background

[0002] Isolation booths are widely known in the prior art for use in sound and / or visual insulation in professional environments. They are generally installed in sites with a noisy environment, such as an open-plan office, an industrial site with noisy equipment and / or machinery, or a public or private space.

[0003] There are several types of isolation cabin.

[0004] In particular, single-person isolation booths, commonly known by the Anglo-Saxon acronym "hub", are known to provide a workspace and sound insulation allowing, for example, telephone calls or work on a laptop.

[0005] Larger isolation booths are also known, which can be occupied by several people, also offering a workspace and sound insulation, which can be used as an office or as a meeting room depending on their size.

[0006] These two types of cabins are different from each other but these cabins are generally made up in both cases of an assembly of acoustic and / or visual insulation panels, assembled to each other or to a structure in dimensions which are adapted to the dimensions of the final cabin.

[0007] These panels, whose size cannot be changed, are assembled to each other or to a structure of a specific size, the size of which also cannot be changed. The result is a cabin whose dimensions are fixed and cannot be modified.

[0008] This configuration poses a problem for companies because they cannot easily and simply increase the capacity of their cabins. Therefore, if their capacity needs change, they must either sell unused cabins and buy new ones adapted to their requirements, or maintain a stock of cabins of varying capacities that can be used as needed. This implies significant investment and requires storage space for the unused cabins. In both cases, these solutions are financially disadvantageous.

[0009] Furthermore, the very existence of different types of cabins necessitates the production of different parts for their manufacture, such as panels and possibly structures adapted to the specific dimensions of the cabins. This diversity of parts required for the manufacture of different cabins increases the overall manufacturing cost of a range of cabins.

[0010] There is therefore a real need for a range of isolation cabins of different sizes that can be produced from common standardized parts, and that can be modified and / or assembled at the user's discretion in order to change their capacity according to their needs. Summary of the invention

[0011] The invention satisfies this need by proposing a modular isolation cabin.

[0012] To this end, the invention proposes a modular isolation cabin, said cabin comprising at least one floor, one roof, and at least two side walls extending between said floor and said roof, said cabin comprising at least one structure supporting at least a portion of the floor, at least a portion of the roof, and at least a portion of said at least two side walls.

[0013] characterized in that said structure is configured to be selectively coupled to at least one other similar structure.

[0014] The use of a structure of a specific type, or the assembly of several structures of the same type, makes it possible to create a modular cabin whose dimensions can be adjusted by simply joining the structures together. This configuration allows, on the one hand, for the cabin's use to be adapted to the user's needs, and on the other hand, for the standardization of the elements necessary for the cabin's construction, thereby reducing the manufacturing cost of a range of such cabins.

[0097] Figures 9, 15 and 21 show a modular isolation booth 10 made according to the invention. As is known per se, such a booth 10 is intended to be placed within professional and / or industrial premises, within premises open to the public or private premises in order to provide sound and / or visual insulation to its occupant(s).

[0098] The cabin 10 comprises at least one floor 12 and a roof 14, and at least two side walls 16 extending between said floor 12 and said roof 14. One of said walls 16 comprises at least one opening 18.

[0099] According to the invention, the cabin 12 comprises at least one structure 20 carrying at least one part 22 of the floor 12, at least one part 24 of the roof 14 and at least one part 26 of said at least two side walls 16. In the remainder of this description, the reference 20 shall designate the structure 20, whether fully assembled or not.

[0100] Said at least one structure 20 is preferably a rigid prismatic structure.

[0101] According to the invention, said at least one structure 20 is configured to be selectively coupled to at least one other similar structure 20.

[0102] This configuration is shown in Figures 9, 15, and 21. Figure 9 shows a cabin 10 comprising a single structure 20. Figure 15 shows a cabin 10 comprising two structures 20 coupled to each other. Figure 21 shows a cabin 10 comprising four structures 20 coupled together.

[0103] Generally speaking, the structure 20 being prismatic, as illustrated in the figures, the structure 10 comprises a lower polygonal frame 28 and an upper polygonal frame 30. By way of non-limiting the invention, the two lower frames 28 and upper frames 30 preferably have the same polygonal shape, each frame 28, 30 having a determined number of associated sides 32, 34. The structure 20 comprises at least two vertical uprights 36 connecting the lower frame 28 and upper frame 30.

[0104] The lower frame 28 supports at least part 22 of said floor 12, the upper frame 30 supports at least part 24 of said roof 14, and said uprights 36 support at least said part of the side walls 16, as will be seen in more detail later in this description with reference to the examples shown.

[0105] According to the invention, the lower frame 28 and / or said upper frame 30 and / or at least one of said uprights 36 is configured to be selectively coupled to another lower frame 28 and / or another upper frame 30 and / or at least one other upright 36 of the similar structure 12.

[0106] It will therefore be understood that, generally speaking, the prismatic structure 20 can take any desired shape. For example, the lower frame 28 and upper frame 30 of each structure 20 could be triangular, pentagonal, hexagonal, octagonal or otherwise in shape without changing the nature of the invention.

[0107] We will now describe, in a non-limiting manner, a preferred embodiment of the invention in which the structure 20 is parallelepiped-shaped. The lower frame 28 and upper frame 30 are rectangular, and more particularly square. Thus, the cabin 10 in Figures 1 to 9 comprises a single parallelepiped-shaped structure 12. The cabin 10 in Figures 10 to 15 comprises two parallelepiped-shaped structures 12 aligned in one row. The cabin 10 in Figures 16 to 21 comprises four parallelepiped-shaped structures 12 aligned in two rows and two columns.

[0108] It will be understood that, without limitation of the invention, the cabin 10 could comprise a greater number of structures 10, aligned in one row, two rows or more.

[0109] Generally, each wall 16 of the cabin 10 comprises at least one panel 26 constituting the part of the wall 16 mentioned above. This panel 26 may, in particular, be an acoustic panel 26a having insulation properties soundproofing, a glazed panel, or a door opening panel 26b. By way of example, Figures 6 and 7 show a soundproofing panel 26a and a door opening panel 26b, which, without limiting the invention, is also a glazed panel. Indeed, as an alternative (not shown), the cabin 12 could also include a fixed glazed panel.

[0110] Without limiting the invention, the vertical uprights 36 could extend between the lower frames 28 and upper frames 30 from any point on the respective sides 32 and 34 of these frames 28, 30. However, preferably, the vertical uprights 36 are fixed to vertices 38, 40 of said lower frames 28 and upper frames 30 which are polygonal, and which are here square in shape.

[0111] Since the lower frame 28 and the upper frame 30 of each structure 20 are, in the example shown here, square in shape, the uprights 36 are consequently fixed to at least three vertices 38 of the lower frame(s) 28 and at least three vertices 40 of the upper frame(s) 30. As can be seen in Figures 5 to 9 and 15, which correspond to the first and second embodiments of the invention in which the structures 20 are aligned in a single row, the uprights 36 are fixed to four vertices 38 of the lower frame(s) 28 and to four vertices 40 of the upper frame(s) 30.As can be seen in Figures 20 and 21, which correspond to the third embodiment of the invention in which the structures 20 are aligned in two rows and two columns, the uprights 36 are fixed to only three vertices 38 of each of the lower frames 28 and to only three vertices 40 of each of the upper frames 30, the lower frame 28 and upper frame 30 each being joined with the other frames 28, 30 by the remaining vertex 38, 40.

[0112] Fig. 2 illustrates the detail of the fixing of a corner post 36 to a vertex 38 of a lower frame 28, it being understood that the fixing is strictly analogous with regard to the fixing of this post to the opposite upper frame 30.

[0113] As can be seen in this figure, the vertices 38 of the lower frame(s) 28 (or respectively of the upper frame(s) 30) have recesses 42 adapted to receive fingers 44 of complementary shape arranged at the ends of the uprights 36. In the example shown here, since the lower frame 28 and upper frame 30 are square, the recesses 42 are preferably also square in cross-section, and the fingers 44 are also square in cross-section. It will be understood that if the frames 28, 30 were to have a different polygonal shape, the recesses 42 would also have a different shape.

[0114] Each upright 36 comprises a profile 46, which is oriented here in the vertical direction. The profile is here, by way of example and without limitation of the invention, a tubular profile 46 with a square cross-section.

[0115] In the example shown here, particularly in Figures 2 and 4, the fingers 44 extend along the length of the tubular profile 46 and consequently have the same cross-section. This configuration is not limiting to the invention, and the fingers 44 could be of different dimensions and / or cross-sections.

[0116] As illustrated in [Fig.2], to ensure the fixing of the fingers 44 in the housings 42, each housing 42 has at least one external fixing wall 47 having a hole 48a suitable for receiving a fixing screw (not shown) passing through said external wall 47 and cooperating with the finger 44 of the upright 36. More particularly, the fixing screw (not shown) is intended to be received in a thread 48b adapted to the screw, this thread being formed in the finger 44 of the upright 36.

[0117] Advantageously, each housing 42 has two external fixing walls 47. Since each lower frame 28 or upper frame 30 is square, the external fixing walls 47 form a 90° angle with each other. The upright 36 is therefore secured in the housing 42 by two substantially perpendicular fixing screws that pass through the holes 48a in the walls 47 and are received in the threaded holes 48b in the finger 44.

[0118] As illustrated more precisely in [Fig.4], to ensure the fixing of the panels 26 to each structure 20, each upright 36 has two vertical wings 50 which extend on either side of the profile 46, each wing 50 extending parallel to one of the adjacent sides 32 of the lower frame 28 or upper frame 30.

[0119] Thus, as shown for example in [Fig. 3], whatever the type of panel 26, it is received between the profiles 46 of two adjacent uprights 36. As shown in [Fig. 4], the panel 26 rests on the flanges 50 of the uprights. The panel 26 is fixed to said flanges 50, notably by screwing. A hole 52 in the panel 26 can be seen in [Fig. 4], which is intended to allow the passage of a screw (not shown) for fixing it to a flange 50.

[0120] It will be understood that without limitation of the invention, the panels 26 could be fixed, alternatively or in combination, directly onto the profiles 46, the wings 50 then only providing a bearing surface for the panels 26 before their fixing onto the profiles 46.

[0121] As previously seen, each structure 20 is configured to be selectively coupled to at least one other similar structure 20, whether this possibility is not used as is the case in the first embodiment of the cabin 10 shown in [Fig.9], which has a single structure 20, or whether it is used as is the case in the second and third embodiments of the cabin 10 shown in Figures 15 and 21, which has several structures 20.

[0122] In the case of a cabin 10 comprising at least two structures 20 coupled to each other, preferably but without limitation of the invention, the coupling is carried out at the level of the lower frames 28 and upper frames 30. In this case, a so-called junction side 32' of the lower frame 28 (respectively a so-called junction side 34' of the upper frame 30) of one of the two structures 20 is coupled to a so-called junction side 32' of another lower frame 28 (respectively a so-called junction side 34' of another upper frame 30) of the other of the two structures 20, as shown in figures 10, 11, 16 and 17.

[0123] There are several ways to achieve the coupling of these sides 32'. In the preferred embodiment of the invention, as shown in Figures 1 and 2, each side 32, 32' of each frame 28 or 30 has at least two holes 54 suitable for being passed through by fixing screws (not shown) intended to pass through similar holes on one side 32' of another adjacent frame 28, 30 to allow the coupling of these frames 28, 3. Thus, it will be understood that each frame 28, 30 can be coupled by any one of its sides 32, thus becoming a so-called joining side 32' with another frame 28, 30 regardless of its position and orientation.

[0124] This configuration is particularly advantageous because it allows, in particular, the coupling of two lower frames 28 or two upper frames 30 without having to significantly alter their orientation. This is especially advantageous when, for example, a cabin 10 is enlarged by adding additional structures 20. It is thus unnecessary to change the orientation of the original cabin 10.

[0125] Furthermore, in the case where at least two structures 20 are coupled together to form the cabin 10, said at least two structures 20 have at least one common vertical post 36. As can be seen in Figures 10, 11, 16 and 17, each common vertical post joins the lower frames 28 in pairs and the upper frames 30 in pairs, these frames being joined along their sides 32', 34'. Each common vertical post overlaps each of the two lower frames 28 and each of the two upper frames 30.

[0126] It will therefore be understood that, in this configuration where the floor 12 and the roof 14 of the cabin are square or rectangular, there are two types of vertical uprights 36, depending on whether these uprights are intended to be fixed to the corners of said floor 12 or said roof 14. Regardless of the embodiment of the cabin 10, the flanges 50 of the uprights fixed to the corners of the frames 28, 30 of said floor 12 and said roof 14 are perpendicular to each other, as shown in [Fig. 4]. In the specific case where the cabin 10 comprises at least two structures 20, and consequently at least two adjacent lower frames 28 and at least two adjacent upper frames 30, the flanges 50 of each of the common uprights 36 are aligned with each other in line with the walls 16, as can be seen, for example, in [Fig. 11].

[0127] Now, with regard to each lower frame 28 or each upper frame 30, each of these frames 28, 30 is preferably made in the form of a welded construction with, as we have seen, tubular sides 32, 34 joined together. This tubular section is preferably square. Thus, the sides of each frame are formed of square cross-section members, which are welded together.

[0128] To ensure the rigidity of the frames 28, 30, each frame has as many stiffening brackets 56 as sides 32, 34, each bracket 56 connecting two adjacent stringers forming consecutive sides 32 or 34. This construction is particularly visible in [Fig. 5].

[0129] Furthermore, generally speaking, each lower frame 28 has at least three height-adjustable feet. In the configuration shown here, in which each lower frame 28 is square, it has four feet fixed 58 along two of its opposite edges 32 parallel to the inside of said lower frame 28, as can be seen more precisely in [Fig. 5]. More specifically, each foot 58 is supported by a jack 60, and it is this jack 60 that is fixed inside the lower frame 28 to one side 32 of said lower frame 28. This configuration ensures stable support for each lower frame 28 and allows for fine adjustment of each support to ensure the stability of the lower frame 28.

[0130] Furthermore, to allow the movement of the cabin 12 comprising one or more structures 20, each lower frame 28 generally carries at least three casters. In the configuration shown here, as can be seen in [Fig. 1], in which each lower frame 28 is square, it comprises two parallel lower cross members 62 extending between two of its opposite edges 32, each carrying two casters 64.

[0131] The floor 12 is constituted, as previously seen, by a floor portion 22 or by the joining of floor portions 22. More particularly, these floor portions are floor slabs 22, each of which is supported by said at least one lower frame 28, as can be seen in [Fig. 6]. More particularly, each floor slab 22 is received between the sides 32 of each lower frame 28. Advantageously, to ensure its support, each floor slab 22 rests on the lower cross members 62, which already carry the casters 64.

[0132] Each floor tile 22 comprises, for example, a medium-density fiberboard (MDF) tile covered with an acoustic carpet tile.

[0133] In the same way as for the floor 12, the roof 14 is made up of a part of a roof 24 or of the joining of parts of a roof 24,

[0134] More particularly, the roof 14 consists of roof boxes 24 which are each supported by said at least one upper frame 30, as shown in Figures 9, 15 and 21.

[0135] Each roof box 24 is made in several parts. It includes, firstly, at least one lower roof slab 66, visible in Figures 5-8, and 20, which is received in each upper frame 30. This lower roof slab 66 is fixed by brackets 68 to at least two opposite sides 34 of the upper frame 30. Preferably, the lower roof slab 66 is fixed by four brackets 68 to the four sides 34 of the upper frame 30. The brackets 68 preferably extend along said at least two opposite sides 34.

[0136] The lower roof slab 66 has at least one ventilation outlet 70. Each roof box has a blower system 72, shown schematically in [Fig.8], which coincides with this ventilation outlet 70.

[0137] The lower roof slab 66 also includes at least one lighting light 74. As illustrated in [Fig.8], each roof box includes an electric lighting system 76 coinciding with the light 74. The blower system 72 and the electric lighting system 76 are connected to a common power supply 80.

[0138] Preferably, each lower roof slab 66 comprises a medium-density fiberboard (MDF) slab covering an acoustic carpet slab.

[0139] Furthermore, each roof box 24 includes an upper roof slab 82 closing the box 24, as shown in Figures 9, 15 and 21. This upper roof slab 82 includes at least one ventilation inlet 84 for supplying the blower system 72.

[0140] The upper roof slab 82 rests on upper edges 86 of the fixing brackets 68 of the lower roof slab 66, and is therefore received between the sides 34.

[0141] With regard to the panels 26, each acoustic panel 26a comprises a melamine panel covered with a layer of acoustic coating. Each hinged panel 26b is received between two uprights 36. Each hinged panel 26 is supported by at least two hinges 88 fixed to the profile 46 of one of the uprights 36, as shown in [Fig. 7]. Each panel 26b is also preferably glazed.

[0142] As we have seen, the cabin 10 comprises a single structure 20 or an assembly of structures 20.

[0143] In the second regulation mode of the invention, which has been shown in Figures 10 to 14, the cabin 10 comprises at least two structures 20 aligned in a single row, as can be seen in Figures 10 and 11. Each pair of structures 20 comprises two opposing common uprights 36, arranged at the opposite ends of the junction sides 32', 34' of their lower 28 and upper 30 frames, and a first cross member 90 fixed to the upper ends of said common uprights 36. This The first cross member 90 is suitable for supporting the connecting sides 34' of the upper frames 30 of the same pair of frames, as can be seen in detail in [Fig. 13]. In the example shown here, the cabin 10 has only two structures 20 and therefore only one single cross member 90. To allow positioning and fixing of the upper frames 30 onto the cross member 90, the first cross member 90 has two vertical lugs 92 which are designed to fit into the recesses 42 of the upper frames 30. Each end of the first cross member 90 has two captive nuts 94, each of which is designed to receive a fixing screw (not shown) passing through the hole 48a in one of the upper frames 30, as shown in [Fig. 14].

[0144] In the third embodiment of the invention shown in Figures 15 to 21, the cabin 10 comprises more than two structures 20, here four structures 20, aligned in two rows and two columns. It will be understood, of course, that the cabin 10 could comprise more than four structures, for example six or eight structures, etc., depending on whether the complete structures 20 are contiguous or not.

[0145] Thus, in the configuration shown in Figures 15 to 21, the two rows and the two columns of structures 20 are contiguous, since each structure consists 20 of a lower frame 28, an upper frame 30, and at least two uprights 36.

[0146] The two rows and the two columns of structures 20 might not be contiguous, particularly in a configuration having more than three structures on each side, a configuration in which the center of the cabin 20 would have at the center of the cabin 10 at least one lower frame 28 and at least one upper frame 30 without uprights 36 arranged between them and extending between the structures 20.

[0147] However, in the example shown here, the structures 20 have common uprights 36 only at the ends of the connecting sides 32', 34' which are located at the edge of the cabin 10, as shown in [Fig. 16]. The cabin 10 has second cross members 92, 94 which are interlaced here. Each second cross member 92, 94 is parallel to two connecting sides 32', 34'. These interlaced second cross members 92, 94 are preferably joined to each other by a half-lap joint known per se from the prior art.

[0148] As before, said second cross members 96, 98 are fixed to the upper ends of the opposing common uprights 36 along the row and column directions, and are suitable for supporting the joining sides 34' of the upper frames 30. As in the previous case, and as can be seen in Figures 18 and 19, the second cross members 96, 98 have lugs 92 at their ends, but at least one of the second cross members, in particular the second cross member 98 which is arranged above the second cross member 96 in the half-lap joint, has at level of the crossing of the second crossbars of the ears 100 intended to be received as before in the housings 42 of the senior executives 30 in order to immobilize them by screws.

[0149] The second crossbeams 96, 98 may be made in one piece, but it will be understood that, for the sake of compactness, the second crossbeams 96, 98 are not necessarily made in one piece. In particular, the second crossbeams 96, 98 may each be made as an assembly of two first crossbeams 90.

[0150] It will be understood that in the hypothetical case where the cabin 10 would have at least three structures 20 on its sides, the second crossbeams 96, 98 would support in the center of the cabin 10 the said upper frames 30 and the absence of uprights 36.

[0151] The invention therefore makes it possible to have a modular isolation cabin 10 that can be adjusted to best suit the needs of users and can be produced at low cost.
