Description

Description Title of the invention: Equipment installation support intended to be installed in an avionics bay, and associated method of obtaining it. technical field

[0001] = This disclosure falls within the domain of equipment installation media intended for installation in an avionics bay. This disclosure relates to a such an installation medium as well as a method for obtaining it. Previous technique

[0002] …— In the aeronautical field, an avionics bay is a mechanical structure of A "shelf" type rack, typically located under the cockpit of an aircraft. The avionics bay is adapted to accommodate various avionics equipment, such as computers, which enable the aircraft to function. In particular, the avionics bay allows to connect the equipment mechanically and electrically in a removable manner avionics to the various onboard systems of the aircraft.

[0003] — In a known manner, each piece of equipment is installed in the avionics bay by via an installation support, also called an electric adaptation chair and mechanical. This installation support allows for electrical and mechanical adaptation. only the equipment corresponding to the avionics bay. Furthermore, the support The installation process facilitates the installation and removal of each piece of equipment during the aircraft maintenance operations.

[0004] — Most of the mounting brackets used in the aeronautical field are conforming to the ARINC 600 standard. As seen in [Fig. 1], a support Installation unit 10 according to ARINC 600 standard includes a back wall 11 and a support piece 12.

[0005] — The bottom wall 11 has a generally rectangular shape delimited by a first edge lateral edge 11A, a second lateral edge 11B, a superior edge 11C and a lower edge 11D. The first lateral edge 11A and the second lateral edge 11B on the one hand, and the edge The upper edge 11C and the lower edge 11D, on the other hand, are substantially parallel between them. The back wall 11 is crossed by a roughly rectangular hole 14. The Hole 14 allows the passage of the avionics connector (not shown) ensuring the connection between the avionics equipment installed on the installation support 10 and the avionics bay (not shown).

[0006] — The support piece 12 comprises a support plate 16, a first wall of guide 18 and a second guide wall 20.

[0007] — The support plate 16 includes a support portion 16-1 extending into a first plane U1-U3 comprising a perpendicular direction U1 and direction U3 between them. Along the direction Ul, the support portion 16-1 extends between an opposite right end portion 16A and a opposite left end portion 16B. Along the direction U3, the support portion 16-1 extends between an opposite front end portion 16C and a rear end portion 16D. The support portion 16-1 comprises a first face 17 and a second face 19, which are opposite in direction. The first face 17 is oriented along a direction U2 perpendicular to the first plane U1-U3, in one direction of this direction U2. The second face 19 is oriented in a second direction of the direction U2, the second direction being opposite to the first. As can be seen in [Fig. 2], the first face 17 is intended to support a single piece of equipment 22 of the aircraft. The first guide wall 18 and the second guide wall 20 extend along the direction U2 opposite each other. In [Fig. 1], the guide walls 18 and 20 are opposite each other along the direction U1. More precisely, the first guide wall 18 and the second guide wall 20 extend along the first direction of the second direction U2. As clearly visible in [Fig.2], the first guide wall 18 comprises an inner face 18-1 and an outer face 18-2, and the second guide wall 20 comprises an inner face 20-1 and an outer face 20-2. The inner faces 18-1 and 20-2 correspond to the faces of each of the guide walls 18, 20 which are opposite each other along the direction Ul. The first guide wall 18 and the second guide wall 20 each have a front portion 24 and a rear portion 26 which are in line with each other along the direction U3. The front portion 24 has a substantially rectangular shape extending between the front end portion 16C and a central portion of the support part 16-1. By "central portion" is meant any portion of the support part 16-1 distinct from the front end portion 16C and the rear end portion 16D and arranged between them. The rear portion 26 has a general right-angled shape extending between the rear end portion 16D and the central portion of the support part 16-1 where the front portion 24 terminates. The rear portion 26 comprises a longitudinal portion 26A, a vertical portion 26B, and a diagonal portion 26C. The longitudinal portion 26A extends along the direction U3 between the central portion of the support part 16-1 and the rear end portion 16D of the support part 16-1. The vertical portion 26B extends along the direction U2 between the longitudinal portion 26A and an upper end portion 26B. The vertical portion 26B of each rear portion 26 is substantially aligned along the direction U1 with the rear end portion 16D of the support plate 16. The diagonal portion 26C extends along the direction U3 and the direction U2 so as to connect the longitudinal portion 26A and the upper end part 261B of the vertical portion 26B at the level of the central portion of the support plate 16. As clearly shown in [Fig.1], the vertical portion 26B of the first guide wall 18 is connected to the first lateral edge 11A of the bottom wall 11, while the vertical portion 26B of the second guide wall 20 is connected to the second lateral edge 11B of the bottom wall 11. Preferably, the vertical portions 26B of the guide walls 18, 20 are connected to the respective lateral edge 11A, 11B of the bottom wall 11 by removable connecting means 27, for example by a plurality of rivets. As can be seen from [Fig.2], the support plate 16, the first guide wall 18 and the second guide wall 20 are formed in one piece, for example from a flat sheet folded along the first direction of the U2 direction. An installation space 28 for the corresponding avionics equipment 22 is thus delimited between the first face 17 of the support part 16-1, the inner face 18-1 of the first guide wall 18 and the inner face 20-1 of the second guide wall 20. A first inner bend radius R1 is formed between the support part 16-1, in particular its first face 17, and the inner face 18-1 of the first guide wall 18. Similarly, a second inner bend radius R2 is formed between the support part 16-1, in particular its first face 17, and the inner face 20-1 of the second guide wall 18.The value of the first inside bend radius R1 and the second inside bend radius R2 depends on the type of sheet metal material and its thickness, among other things. Preferably, the first inside bend radius R1 and the second inside bend radius R2 are equal. The mounting bracket 10, which meets the requirements of ARINC 600, is designed for the installation of a single piece of equipment 22. Specifically, ARINC 600 defines the size of each mounting bracket based on the size of the avionics equipment it can accommodate. This size is expressed in MCUs (Modular Concept Units). ARINC 600 requires that the mounting space 28 have a width L1, measured between the inner faces 18-1, 20-1 of the two guide walls 18, 20, greater than a width L2 of the equipment 22 it accommodates. Thus, a mechanical clearance J is created between each of the inner faces 18-1, 20-1 of the guide walls 18, 20 and the corresponding equipment 22. This allows the equipment 22 to be easily plugged in and unplugged from the avionics bay even when manufacturing and assembly dispersions occur. However, since the mounting bracket 10 according to the ARINC 600 standard is sized to accommodate only one piece of equipment 22, it is necessary to multiply the number of mounting brackets 10 in the bay in order to install all the equipment avionics 22 necessary for the proper functioning of the aircraft. The weight of the aircraft is therefore increased and a large production of installation supports 10 is necessary to equip all aircraft. Furthermore, nowadays the use of modular avionics equipment is increasingly replacing avionics equipment conforming to the ARINC 600 standard. This modular equipment sometimes has a greater weight than equipment conforming to the ARINC 600 standard. Therefore, in order to compensate for this increased weight of the modular equipment, it is advisable to use the same mounting bracket for several pieces of equipment. However, the first bend radius R1 and the second bend radius R2 mean that at the interface between the first face 17 of the support part 16-1 and, respectively, the inner face 18-1 of the first guide wall 18 and the inner face 20-1 of the second guide wall 20, the width of the mounting space 28 is significantly less than its width L1 measured between the two guide walls 18, 20. Also, as can be seen in [Fig.[3] When two avionics devices 22 are installed in the same bracket 10, at least one corner of one of the devices 22 collides with one of the bend radii R1 and R2. This disrupts the correct installation of each avionics device 22 in the bracket 10. Summary. This disclosure improves the situation. To this end, an installation support is proposed for at least one piece of equipment intended to be installed in an avionics bay, the support comprising: - a one-piece support plate for said equipment comprising a support portion extending in a first plane and connected at its extremities along a first direction of said first plane to a first lateral end portion and to a second lateral end portion, the support portion comprising a first face oriented along a second direction perpendicular to said first plane and along a first direction of said second direction and intended to receive said equipment in support, and a second face opposite to the first face and oriented along a second direction of said second direction, - a first guide wall and a second guide wall arranged opposite each other along said first direction, the first guide wall being connected to the first lateral end part of the support plate, the second guide wall being connected to the second lateral end part of the support plate, the first and second guide walls extending substantially perpendicularly to said first plane; in which the first lateral end part and the second lateral end part extend in projection relative to said foreground and along the second direction of the second direction. The one-piece support plate thus includes lateral end sections folded in the second direction. These lateral end sections are therefore folded in the opposite orientation to the folds that form the first and second guide walls in the support conforming to ARINC 600 described above. Therefore, unlike prior art, this reversed orientation of the end sections—that is, in the second direction rather than the first—frees up space at a corner of equipment mounted on the support.It is understood that this particular conformation makes it possible to create a respective housing, in the second direction, between the first lateral end part and the bottom surface of equipment carried by the support part, and between the second lateral end part and the bottom surface of another or the same equipment carried by the support part. This allows for the full utilization of the available space between the two guide walls, enabling the installation of more than one piece of equipment per mounting bracket. This minimizes the number of mounting brackets required to install all the equipment in the avionics bay, thereby reducing the bay's weight and / or compensating for the increased weight of modular equipment. Furthermore, installing multiple pieces of equipment on the same mounting bracket reduces play in the first direction between each piece of equipment and the inner faces of the guide walls. The inner faces are the opposite faces of the guide walls in the first direction. In this text, the direction of a face, specifically the first and second faces of the support part, refers to the direction of the normal vector to that face. The direction of the face corresponds to the direction of this normal vector. In the various figures in this text, the first plane corresponds to the U1-U3 plane, which is a horizontal plane, and the first direction of this U1-U3 plane corresponds to the direction U1. The direction U2 is a vertical direction in the figures. As will be detailed later, in order for the first and second lateral end sections to project outwards relative to the foreground and along the second direction, a bend is made at the level of the first and second end sections respectively. However, according to an alternative, the first and second end sections could be formed by welding two pieces extending outwards relative to the foreground and along the second direction to each end of the support section. According to another aspect, at least one of the first lateral end part and the second lateral end part includes a first connecting portion to said support part, this first connecting portion being curved and comprising a first face which is connected to the first face of the support wall and which is convexly curved. In one embodiment, this first face could be concave or even substantially flat and, for example, extend along the second direction. It is understood, however, that a convex curved face can be produced by folding one end of a flat sheet of metal, the fold forming the convex curved face. Preferably, the first and second end sections each comprise a first connecting portion. In some cases, the first connecting portion directly connects the support portion of the mounting plate to one of the guide walls. Advantageously, in such cases, the first connecting portion is connected to the corresponding guide wall at a point far from the foreground in the second direction. This allows the respective recess to be created between each end section and the bottom surface of the equipment supported by the support portion. According to another aspect, the first connecting portion is connected at its opposite end to the support part to a second connecting portion. The second connecting portion is thus an extension of the first connecting portion. According to the invention, the second connecting portion of each lateral end part is directly connected to the respective guide wall. Therefore, in these cases, the first connecting portion does not directly connect the support portion of the support plate and one of the guide walls. Rather, in these cases, the support portion of the support plate and one of the guide walls are connected to each other via the first and second connecting portions. To create the housing between each lateral end part and the bottom surface of the equipment carried by the support part, the second connecting portion is connected to the corresponding guide wall at a point far from the foreground along the second direction of the second direction. According to another aspect, the second connecting portion is curved and has a first face which is connected to the first face of the first connecting portion and which is concave curved. In one variation, the first face of the second connecting portion could be convex or even essentially flat and, for example, extend along the second direction. It is understood, however, that a concave curved face can be created by folding one end of a flat sheet of metal, the fold forming the concave curved face. From another perspective, the second connecting section is essentially flat and extends along the second direction. According to another aspect, the second connecting portion extends along the second direction from the first connecting portion. In one variant, the second connecting section could extend along the first direction of the second direction. According to another aspect, at least one of the first lateral end part and of the second lateral end part is connected by removable connecting means to, respectively, the first guide wall and the second guide wall. In one example, the two guide walls are connected to their respective end sections by removable fasteners. These removable fasteners could be, for example, screws or rivets. Using removable fasteners allows for a simple and inexpensive connection of the first and second guide walls to the support plate. Furthermore, these removable fasteners make it easy to correct any assembly errors. To connect the support plate and the guide walls via removable connecting means, the connecting portion of each lateral end section that is directly connected to one of the guide walls may include at least one additional opening to an opening in the respective guide wall. The opening in the guide wall and the additional opening in the connecting portion directly connected to that guide wall are shaped to receive the removable connecting means. As previously mentioned, in some cases the first connecting portion is directly connected to one of the guide walls, and in other cases it is the second connecting portion that is directly connected to one of the guide walls. According to another aspect, at least one of the guide walls and the support plate are formed from a single piece. Preferably, the two guide walls and the support plate are formed from a single piece. This one-piece configuration can be advantageously achieved when the first and second end sections each include a first and second curved connecting portion, as described previously. Indeed, by providing a flat plate and creating a first fold to form the first connecting portion of the first end section, followed by a second fold to form the second connecting portion of the first end section and the first guide wall, a first subassembly of the installation support is obtained. It is understood that the second end section, shaped similarly and connected to the second guide wall, yields a second subassembly of the installation support, similar in form to the first subassembly. According to another aspect, a method is proposed for obtaining an installation support for at least one piece of equipment intended to be installed in an avionics bay as described above, the method comprising: a) supply of a one-piece support plate comprising a support part extending in a first plane and connected at its ends along a first direction of said plane to a first lateral end part and to a second lateral end part, the support part comprising a first face oriented along a second direction perpendicular to said first plane and along a first direction of said second direction and intended to receive said at least one piece of equipment in support, and a second face opposite to the first face and oriented along a second direction of said second direction; b) making a fold at the level of the first part of the lateral end so that the first part of the lateral end extends in projection relative to said foreground and along the second direction of the second direction; c) making a fold at the level of the second lateral end part so that the second lateral end part extends in projection relative to said foreground and along the second direction of the second direction. The installation support according to the invention is therefore obtained from a process that is easy to implement. According to another aspect, the process further includes carrying out a second folding of at least one of the first end side part and the second end side part. The second fold makes it easy to obtain the second connecting portion of each lateral end part when at least one of the guide walls and the support plate are formed from a single piece.

Fig. 9 [Fig.9] shows a schematic perspective view of an installation support for equipment intended to be installed in an avionics bay according to a second embodiment of the invention. Description of the implementation methods An installation support 50 for at least one piece of equipment intended to be installed in an avionics bay will now be described according to a first embodiment of the invention illustrated in figures 4 to 6. The installation support 50 includes a support plate 52 for the equipment, a first guide wall 54A and a second guide wall 54B. The support plate 52 is preferably one piece and comprises a support part 56, a first lateral end part 58A and a second lateral end part 58B. The support portion 56 extends in the first plane U1-U3 described above with reference to [Fig. 1]. Along the direction U1, the support portion 56 extends between a right end portion 56A and a left end portion 56B, clearly visible in [Fig. 5]. Along the direction U3, the support portion 56 extends between a front end portion 56C and a rear end portion 56D, visible in Figures 4 and 5. The support part 56 comprises a first face 57 and a second face 59. The first face 57 is oriented along the direction U2 perpendicular to the plane U1-U3 following a first direction SI of this direction U2. The second face 59 is oriented along the direction U2 in a second direction S2 of this direction U2. The second direction S2 is opposite to the first direction SI. In particular, in the figures in this text, the first direction S1 points upwards while the second direction S2 points downwards. The first face 57 is intended to receive one or more pieces of equipment 22 of the aircraft in support, as seen in [Fig.6]. As can be seen from [Fig.4], the support part 56 is traversed between the first face 57 and the second face 59 by holes 60-1 and holes 60-2. The holes 60-1 are smaller than the holes 60-2. As shown in [Fig. 5], each hole 60-1 is shaped to receive a removable connecting means 63 for attaching the support portion 56 to an aircraft interface part 61. Each hole 60-2 is arranged oppositely in the direction U2 with a counterbore 61A in the aircraft interface part 61. Each hole 60-2 and each respective counterbore 61A are specifically shaped to receive a removable connecting means 65 for attaching the mounting bracket 50 to the aircraft. The removable connecting means 63, 65 are, for example, a screw or a rivet. In some cases, holes 60-1 and 60-2 may be connection holes allowing the passage of cables connecting to the avionics bay of the equipment installed on the support section. These holes 60-1 and 60-2 may also be ventilation holes facilitating the cooling of the equipment in operation. The first lateral end part 58A is connected to a first end of the support part 56 included in the right end portion 56A. As can be clearly seen from [Fig.6], the first lateral end part 58A comprises a first connecting portion 62A and a second connecting portion 64A. The first connecting portion 62A extends from the first end of the support part 56 so as to protrude relative to the foreground U1-U3 and along the second direction S2 of the direction U2. The first connecting portion 62A is in particular curved. The first connecting portion 62A comprises a first face 66A and a second face 68A. The first and second faces 66A, 68A are opposite. As clearly visible in [Fig. 6], the first face 66A of the first connecting portion 62A is convex and is connected to the first face 57 of the support part 56. More precisely, the first face 66A of the first connecting portion 62A is in line with the first face 57 of the support part 56. The second face 68A of the first connecting portion 62A is concave and is connected to the second face 59 of the support part. More precisely, the second face 66A of the first connecting portion 62A is in the pro- length of the second face 59 of the support part 56. The second connecting portion 64A extends from the end of the first connecting portion 62A opposite the support part 56. In the embodiment shown in Figures 4 to 6, the second connecting portion 64A is substantially planar and extends along the direction U2. In particular, the second connecting portion 64A extends along the second direction S2 of U2 from the first connecting portion 62A. The second connecting portion 64A comprises a first face 70A and a second face 72A. The first and second faces 70A and 72A are opposite. As clearly visible in [Fig. 6], the first face 70A of the second connecting portion 64A is flat and is connected to the first face 66A of the first connecting portion 62A. More precisely, the first face 70A of the second connecting portion 64A is an extension of the first face 66A of the first connecting portion 62A. The second face 72A of the second connecting portion 64A is flat and is connected to the second face 59 of the first connecting portion 62A. More precisely, the second face 72A of the second connecting portion 64A is an extension of the second face 59 of the first connecting portion 62A. As will be detailed later, the second connecting portion 64A is traversed between its first face 70A and its second face 72A by one or more holes 74, visible in particular in [Fig. 5]. The holes 74 are shaped to receive connecting means 76. The connecting means 76 are preferably removable, for example rivets. The connecting means 76 allow the first guide wall 54A to be connected to the support plate 52. The second lateral end part 58B is connected to a second end of the support part 56. The second end of the support part 56 is included in the left end portion 56B. The second end section 58B is identical or similar to the first end section 5S8A. Therefore, for the sake of brevity, the second end section 58B will not be described in detail below. The description given above of the elements forming the first end section 58A applies to the elements forming the second end section 58B that are identical or similar to those elements of the first end section 5S8A. In the figures, the elements forming the second end section 58B that are identical or similar to those of the first end section 58A are referenced with the same part number, but replacing the letter A with B. For example, part number 62B in [Fig. 6] corresponds to the first connecting part of the second end section 58B, which is identical or similar. structurally to the first connecting portion 62A of the first side end part S8A. The only difference between the second side end part 58B and the first side end part 5S8A is that, of course, the first connecting portion 62B extends from the second end of the support part 56, instead of extending from the first end of the support part 56. Furthermore, the second connecting portion 64B of the second lateral end section is also traversed between its first face 70B and its second face 72B by one or more holes 74 shaped to receive connecting means 76 as described above. In this case, the connecting means 76 allow the second guide wall 54B to be connected to the support plate 52. Advantageously, the first guide wall 54A and the second guide wall 54B are connected to the support plate 52 at one or more points distant from the plane U1-U3 along the second direction S2 of direction U2. Also, when a piece of equipment 22 is carried by the support part 56, a first recess 75 is formed between a bottom surface 22-1 of the equipment 22 and the first lateral end part S8A, and a second recess 79 is formed between the bottom surface 22-1 of the same or another piece of equipment 22 and the second lateral end part 58B. Thanks to the recesses 75 and 79, space is freed up at a corner of the equipment 22 installed on the mounting support 50. The first guide wall 54A and the second guide wall 54B will now be described. The first guide wall 54A and the second guide wall 54B extend along the direction U2 opposite each other. In particular, the guide walls 54A and 54B are opposite each other along the direction Ul. More precisely, the first guide wall 54A and the second guide wall 54B extend along the first direction of the second direction U2. As clearly visible in [Fig. 6], the first guide wall 54A comprises an inner face 78A and an outer face 80A, and the second guide wall 54B comprises an inner face 78B and an outer face 80B. The inner faces 78A and 78B correspond to the faces of each of the guide walls 18, 20 which are opposite each other along the direction U1. The first guide wall 54A and the second guide wall 54B each have a front portion 84 and a rear portion 86 which are in line with each other along the direction U3. The front portion 84 has a substantially rectangular shape extending between the front end portion 56C and a central portion of the support part 56. By "central portion" is meant any portion of the support part 56 distinct from the front end portion 56C and rear end portion 56D and arranged between them. The rear portion 86 has a general right-angled shape extending between the rear end portion 56D and the central portion of the support part 56 where the front portion 54 of the respective guide wall 54A, 54B terminates. The rear portion 86 comprises a longitudinal portion 86-1, a vertical portion 86-2 and a diagonal portion 86-3. The longitudinal portion 86-1 extends along the direction U3 between the central portion of the support part 56 and the rear end portion 56D of the support part 56. The longitudinal wall 86-1 of each guide wall 54A, 54B includes one or more holes 89 complementary to the holes 74 of the second connecting portions 64A. The holes 89 allow the passage of the connecting means 76, which makes it possible to connect each guide wall 54A, 54B to one of the connecting portions 64A. The vertical portion 86-2 extends along the direction U2 between the longitudinal portion 86-1 and an upper end portion 861. The vertical portion 86-2 of each rear portion 86 is substantially aligned along the direction U1 with the rear end portion 56D of the support portion 56. The diagonal portion 86-3 extends along the direction U3 and the direction U2 so as to connect the longitudinal portion 86-1 and the upper end portion 861 of the vertical portion 86-2 at the level of the central portion of the support plate 56. One or more openings 85 can be included in the guide walls 54A, 54B. Thanks to these openings 85, the weight of the installation support 50 is reduced. As clearly shown in [Fig.4], the first guide wall 54A and the second guide wall 54B are connected along the direction U1 by a bottom wall 90. The bottom wall 90 has a substantially rectangular shape and includes one or more holes 92 which allow the passage of the avionics connector (not illustrated) ensuring the connection between each piece of equipment 22 carried by the installation support 10 and the avionics bay. In the embodiment shown in Figures 4 to 6, the bottom wall 90, the first guide wall 54A and the second guide wall 54B form a single piece. An upper wall 94 can also be provided to connect, along the direction Ul, the upper end parts 861 of the vertical portion 86-2 of each guide wall 54A, 54B. In the embodiment shown in Figures 4 to 6, the upper wall 94 also forms a single piece with the bottom wall 90, the first guide wall 54A and the second guide wall 54B. The guide walls 54A, 54B allow the installation of each piece of equipment to be guided so that it can be correctly connected to the avionics connectors. As can be seen in particular in Figures 5 and 6, at least one intermediate wall 98 can be arranged between the guide walls 54A, SB. The intermediate wall 98 has a shape similar to that of the guide walls 54A and 54B. Therefore, it will not be described in detail. This intermediate wall 98 is preferably welded to the first wall 57 of the support portion 56. The intermediate wall 98 can also be welded to the upper wall 94 when one is provided. The intermediate wall 98 allows for better orientation of the installation of each piece of equipment 22, particularly when the support 50 carries several avionics pieces of equipment. A method for obtaining the installation support 50 will now be described with reference to figures 7 and 8. The process includes a step of supplying the one-piece support plate 52 comprising the support part 56, the first lateral end part S8A and the second lateral end part 58B. The one-piece support plate is in particular a sheet 97, preferably of constant thickness. Figure 7 shows a schematic view of the sheet metal 97, on which the various parts of the support plate 52 are referenced, including the support portion 56, the first connecting sections 62A, 62B, and the second connecting sections 64A, 64B. It should be noted that, initially, the sheet metal 97 is flat, so these parts are not differentiated from one another. The lines separating each of these parts in Figure 7 are merely virtual lines representing the intersection between each part of the support plate 52 that will be obtained after the process of producing the support 50 has been carried out. The process involves folding the first lateral end portion 5S8A so that the first lateral end portion projects outward relative to the plane U1-U3 and along the second direction S2 of U2. More specifically, this fold aims to obtain the first connecting portion 62A and the second connecting portion 64A. To this end, the fold is made around a fold line 1A. As shown schematically in [Fig. 7], the fold line 1A is substantially offset from the intersection between the support portion 52 and the first connecting portion. In particular, the fold line 1A lies within the first connecting portion 62A. A similar folding step is also performed on the second lateral end section 58B, so that the second lateral end section projects outward relative to the U1-U3 plane and along the second direction S2 of the U2 direction. More precisely, this folding aims to obtain the first connecting section 62B and the second connecting section 64B. To this end, this folding is carried out around a fold line 1B which is substantially offset from the intersection between the support section 52 and the first connecting section. In particular, the 1B bend line is included in the first portion of the 62B connection. The support plate 52, as illustrated in [Fig. 6], is obtained after these bending operations performed on the first end piece 58A and the second end piece 5S8B. It should be noted that the order in which these bending operations are presented here is not exhaustive. In particular, when these bends are performed by a bending machine, the order depends, among other things, on the configuration of the bending machine used. Furthermore, the process includes the provision of the first and second guide walls 54A, 54B. As indicated above, in the embodiment shown in Figures 4 to 6, the guide walls 54A, 54B form a single piece with the bottom wall. In particular, the guide walls 54A, 54B are obtained by making two folds on a sheet 99 shown in [Fig. 8]. The sheet 99 is flat and of constant thickness. As can be seen in this figure, the sheet 99 comprises, on either side of a rectangular portion having the shape of the bottom wall 90, a portion having the shape of the first guide wall 54A and another portion having the shape of the second guide wall. Therefore, to obtain the desired orientation of the first guide wall 54A, a first fold of the sheet 99 is made around a fold line 3A slightly offset towards the first guide wall 54A.Similarly, to obtain the desired orientation of the second guide wall 54B, a first bend in the sheet metal 99 is made around a bend line 3B slightly offset towards the second guide wall 54B. It should be noted that the order in which these bending operations have been presented here is not exhaustive. In particular, when these bends are performed by a bending machine, the order depends notably on the configuration of the bending machine used. Once the guide walls 54A, 54B are in the desired orientation, each guide wall is connected to the support plate 52 by means of the connecting means 76 described above. In particular, as previously stated, the first guide wall 54A is connected to the second connecting portion 64A of the first lateral end part 58A, while the second guide wall 54B is connected to the second connecting portion 64B of the second lateral end part 58B. As indicated above, the guide walls 54A, 54B are connected to the support plate 52 at a point far from the plane U1-U3 along the second direction S2, which allows the formation of the housings 75, 79 described above. It should be noted that the process described here may include, before the various bends of the sheets 97, 99, the creation of the holes and openings provided on the support plate 52, the guide walls 54A, 54B and the bottom wall 90. The process may in addition include a welding step of one or more interlayer walls 98 on the first face 57 of the support part 56. Now, with reference to [Fig.9], will be described an installation support 100 for at least one piece of equipment intended to be installed in an avionics bay according to a second embodiment of the invention. The support 100 includes a support plate 152 comprising a support part 156, a first side end part 158A and a second side end part 158B. The support part 156 is similar to the support part 56 of the support 50 described above with reference to figures 4 to 6 and will therefore not be described again. The first side end part 158A and the second side end part 158B each comprise a first connecting portion 162A, 162B and a second connecting portion 164A, 164B respectively. The first connecting portions 162A, 162B are similar to the first connecting portion 62A described with reference to [Fig.6] and will therefore not be described again. The second connecting portions 164A, 164B differ from the connecting portion 64A described with reference to [Fig. 6] in that they are curved instead of flat. In particular, the second connecting portions 164A, 164B each have a first face 170A, 170B which is concave and curved. The remaining characteristics of the second connecting portion 64A described above are applicable to the second connecting portions 164A, 164B. The support 100 also includes a first guide wall 154A and a second guide wall 154B. Structurally, the first guide wall 154A and the second guide wall 154B are, for example, identical to the guide walls 54A and 54B of the support 50 in Figures 4 to 6. However, as clearly illustrated in [Fig. 9], in the support 100 the guide walls 154A and 154B form a single piece with the support plate 152. In particular, the guide wall 154A extends along the direction U2 in the first direction SI from the end of the second connecting section 164A opposite the first connecting section 162A. The guide wall 154B extends along the direction U2 in the first direction S1 from the end of the second connecting section 164B opposite the first connecting section 162B. It is noted that the intersection between the guide wall 154A and the second connecting section 164A is located away from the U11-U3 plane along the second direction of U2. Similarly, the intersection between the guide wall 154B and the second connecting section 164B is located away from the U1-U3 plane along the second direction of U2. Therefore, a first housing 175 is formed between the bottom surface 22-1 of the equipment 22 and the first lateral end part 158A, and a second housing 179 is formed between the bottom surface 22-1 of the same or another piece of equipment 22 and the second lateral end part 158B. Thanks to the housings 175, 179, space is freed up at a corner of the equipment 22 installed on the mounting support 50. The guide walls 154A, 154B being formed in one piece with the support plate 152, in this embodiment the guide walls 154A, 154B and the second connecting portions 164A, 164B do not include holes 74, 89 for receiving the connecting means 76. In this embodiment, the back panel (not shown) facilitating the electrical connection of each piece of equipment 22 is preferably a separate part from the guide walls 154A, 154B and arranged so as to connect them in the UI direction. The back panel can be connected to the guide walls 154A, 154B by means of removable connecting means, such as rivets 27. To obtain the installation support 100, a process similar to that described above with reference to Figures 7 and 8 can be implemented. However, since the guide walls 154A, 154B form a single piece with the support plate 152, a sheet metal (not shown) is used comprising a portion having the shape of the one-piece support plate 52 and, on each side of this portion, a portion having the shape of the guide walls 154A, 154B. The process comprises the same steps as those applied to the sheet metal 97 described above with reference to [Fig. 7]. However, the process for obtaining the support 100 also includes making a fold at the second connecting portion 164A to form the first guide wall 154A, and making a fold at the second connecting portion 164B to form the second guide wall 154B. As indicated above, the guide walls 154A and 154B extend along the first direction S1 of the direction U2. This additional folding, compared to the method of obtaining support 50, is carried out so that the fold line between each guide wall 154A, 154B and each second connecting portion 164A, 164B lies in a plane parallel to the U1-U3 plane but away from it in the second direction S2 of the U2 direction. This makes it possible to form the housings 175, 179 described above. Of course, since the guide walls 154A, 154B are formed as a single piece with the support plate, the step to connect the guide walls 154A, 154B is not implemented to obtain the support 100. However, a step to connect the bottom wall between the two guide walls 154A, 154B can be implemented. Note that the installation supports 50, 100 described above allow the entire available width between the guide walls 54A, 54B or 154A, 154B to be used for install one or more equipment 22. Unlike the previous technique, no bend radius collides with the equipment 22 installed in the support 50, 100 thanks to the fact that the first lateral end part 58A, 158A and the second lateral end part 58B, 158B of these supports 100 extend in projection relative to the plane U1-U3 but along the second direction S2 of the second direction U2.
