Description

[0001] TITLE: Equipment casing and associated equipment

[0002] The present invention relates to a housing for equipment, in particular sensitive equipment.

[0003] Sensitive equipment, for example using sensitive components and / or containing encrypted data, must be protected against physical intrusions, in particular to guard against attacks such as the extraction of goods and data.

[0004] Such components are usually arranged in a closed case consisting of a plurality of walls.

[0005] It is known to install opening detection mechanisms that result in the erasure of sensitive data and / or render components non-functional if the case is opened, for example if one of the walls is removed.

[0006] These opening detection mechanisms are generally installed on each of the removable parts of the case, and in particular on each of the walls.

[0007] However, such opening detection mechanisms are not entirely satisfactory.

[0008] Indeed, these mechanisms are expensive and complex to design and integrate into equipment.

[0009] Furthermore, these mechanisms require a constant power supply to ensure continuous operation, necessitating the installation of a battery. A battery is bulky and also requires additional maintenance.

[0010] In addition, such mechanisms can lead to false detections of openings (also known as "false positives"), for example in the case of vibrations.

[0011] The aim of the invention is therefore to offer an equipment box that allows protection against physical intrusions in a reliable and economical manner.

[0012] To this end, the invention relates to a housing for equipment comprising:

[0013] - a structure,

[0014] - a set of walls defining between them a closed internal volume, the set of walls comprising:

[0015] • at least one first wall fixed to the structure; • at least one second wall fixed to the structure, the second wall comprising a first locking element mechanically blocking the first wall; and

[0016] • at least one third wall fixed to the structure, the third wall comprising a second locking element mechanically blocking the second wall.

[0017] Since the first panel is mechanically locked by the second panel, which is itself locked by the third panel, the third panel is the only one that can be removed first. Due to the locking mechanisms, the enclosure must therefore be disassembled in a specific order, which complicates the process and thus enhances protection against equipment tampering. Because the locking mechanisms are mechanical, they are economical and reliable.

[0018] According to other advantageous aspects of the invention, the housing comprises one or more of the following features, taken individually or in all technically possible combinations:

[0019] - The third wall includes a third locking element that mechanically blocks the first wall.

[0020] - The case comprises two first walls, the second wall comprising two first locking elements which mechanically block each of the first two walls respectively.

[0021] - The casing comprises two second walls, the third wall comprising two second locking elements mechanically blocking each of the two second walls respectively.

[0022] - The housing includes a fourth wall fixed to the structure, at least one of the first and second walls comprising a third locking element mechanically blocking the fourth wall.

[0023] - The third locking element is a lug configured to fit around a corresponding bead on the fourth wall.

[0024] - The closed internal volume is in the shape of a rectangular parallelepiped, the first wall being perpendicular to a transverse axis, the second wall being perpendicular to a vertical axis perpendicular to the transverse axis, and the third wall being perpendicular to a longitudinal axis perpendicular to the transverse axis and to the vertical axis.

[0025] - The first wall includes at least one longitudinal edge extending parallel to the longitudinal axis, the second wall includes at least one longitudinal edge extending parallel to the longitudinal axis and in contact with the corresponding longitudinal edge of the first wall, the first locking element being a rim extending in projection along the vertical axis of the corresponding longitudinal edge of the second wall and partially covering the first wall.

[0026] - The second wall includes at least one transverse edge extending parallel to the transverse axis, the third wall includes at least one transverse edge extending parallel to the transverse axis and in contact with the corresponding transverse edge of the second wall, the second locking element being a rim extending in projection along the longitudinal axis of the corresponding transverse edge of the third wall and partially covering the second wall.

[0027] The invention also relates to equipment comprising a housing as described above and at least one component disposed in the internal volume.

[0028] The invention will become clearer upon reading the following description, given solely by way of non-limiting example, and made with reference to the drawings in which:

[0029] Figure 1 is a schematic perspective view of equipment according to the invention, the equipment comprising a housing;

[0030] Figure 2 is a schematic exploded view of the housing in Figure 1;

[0031] Figure 3 is a cross-sectional view along the section plane lll-lll of the housing in Figure 1; and

[0032] Figure 4 is a cross-sectional view along the cutting plane I Vl V of the housing in Figure 1.

[0033] Figure 1 shows equipment 10 according to the invention.

[0034] Equipment 10 includes a housing 12 and at least one component 14.

[0035] Advantageously, the equipment 10 further includes an opening detection mechanism 15.

[0036] In the example illustrated in Figure 1, the equipment 10 comprises a single component 14 arranged inside the housing 12.

[0037] Component 14, for example, is a sensitive component, specifically a sensitive electronic component.

[0038] By "sensitive" we mean any element or data whose disappearance or capture by a third party could harm the interests of the equipment owner 10.

[0039] In particular, component 14 stores and / or uses sensitive and / or secret elements or data, including encrypted data.

[0040] As can be seen in Figure 2, the housing 12 comprises a structure 16 and a set 18 of walls. In the particular example illustrated in the figures, the housing 12 is rectangular in shape, specifically defining an associated orthonormal coordinate system comprising a longitudinal axis X, a transverse axis Y and a vertical axis Z.

[0041] Structure 16 defines in particular the framework of the housing 12.

[0042] For example, structure 16 includes a set of beams 20x, 20y, 20z.

[0043] In the particular example illustrated in the figures, the structure 16 comprises, for example, twelve beams, including four longitudinal beams 20x extending along the longitudinal axis X, four transverse beams 20y extending along the transverse axis Y, and four vertical beams 20z extending along the vertical axis Z. The beams 20x, 20y, 20z are connected to each other in such a way as to define the corners of the rectangular parallelepiped.

[0044] Beams 20x, 20y, 20z of beam set 18 are, for example, metal beams.

[0045] Beams 20x, 20y, 20z preferably have a rectangular, and in particular square, cross-section.

[0046] The set 18 of walls comprises a plurality of walls 22, 24, 26, 28 fixed to the structure 16 and defining between them a closed internal volume 30.

[0047] In the particular example illustrated in the figures, the closed internal volume 30 is rectangular parallelepiped in shape.

[0048] The closed internal volume 30 defines a volume, for example, between 5 cm 3 and 2 m 3 .

[0049] As can be seen in Figure 1, component 14 is arranged inside the closed internal volume 30.

[0050] The set of walls 18 includes at least a first wall 22, at least a second wall 24 and at least a third wall 26.

[0051] In one particular example, the set of 18 walls also includes a fourth wall 28.

[0052] For example, in the embodiment illustrated in the figures, the set 18 of walls comprises six walls defining between them the closed internal volume 30 of rectangular parallelepiped shape.

[0053] More specifically in this particular example, the set 18 of walls comprises two first walls 22, two second walls 24, a third wall 26 and a fourth wall 28.

[0054] Each first wall 22 extends, for example, perpendicularly to the transverse axis Y.

[0055] In a particular embodiment, each first wall 22 is a plate, notably substantially rectangular. More precisely, each first wall 22 extends, along the longitudinal axis X, between a first vertical edge 22z-1 and a second vertical edge 22z-2, each extending parallel to the vertical axis Z. Each first wall 22 extends, along the vertical axis Z, between a first longitudinal edge 22x-1 and a second longitudinal edge 22x-2, both extending parallel to the longitudinal axis X.

[0056] Each first wall 22 is fixed to the structure 16, for example by screws 32.

[0057] For example, each of the first 22x-1 and second 22x-2 longitudinal edge is fixed to one of the longitudinal beams 20x of the structure 16, for example by means of a plurality of screws 32. Each of the first 22z-1 and second 22z-2 vertical edge is fixed to one of the vertical beams 20z of the structure 16, for example by means of a plurality of screws 32.

[0058] Each first wall 22 preferably includes a clearance 34x provided on at least one of the first longitudinal edge 22x-1 and the second longitudinal edge 22x-2, and preferably on each of the first longitudinal edge 22x-1 and the second longitudinal edge 22x-2, as can be seen in Figure 2.

[0059] Advantageously, each first wall 22 also includes a clearance 34z provided on at least one of the first vertical edge 22z-1 and the second vertical edge 22z-2, and in particular on the first vertical edge 22z-1 as can be seen in Figure 2.

[0060] More specifically, as can be seen for example in Figure 3, the thickness of the first wall 22 is reduced at each of the clearances 34x, 34z.

[0061] Preferably, the screws 32 are fixed at each of the clearances 34x, 34z.

[0062] In the embodiment illustrated in the Figures, the first wall 22 includes a fourth locking element 36, specifically configured to mechanically lock the fourth wall 28.

[0063] More specifically, the fourth locking element 36 of the first wall 22 is a lug 38, in particular extending in projection from the second vertical edge 22z-2 of the first wall 22.

[0064] As can be seen in Figure 2, the lug 38 has a hook shape, specifically a semi-circular cross-section in the XY plane.

[0065] Each second wall 24 extends, for example, perpendicularly to the vertical axis Z.

[0066] In particular, in one embodiment, the two second walls 24 each extend between the two first walls 22 along the transverse axis Y. In a particular embodiment, each second wall 24 is a plate, in particular substantially rectangular.

[0067] More precisely, each second wall 24 extends, along the longitudinal axis X, between a first transverse edge 24y-1 and a second transverse edge 24y-2 extending parallel to the transverse axis Y. Each second wall 24 extends, along the transverse axis Y, between a first longitudinal edge 24x-1 and a second longitudinal edge 24x-2, each extending parallel to the longitudinal axis X.

[0068] Each second wall 24 is fixed to the structure 16, for example by screws 32.

[0069] For example, each of the first 24x-1 and second 24x-2 longitudinal edge is fixed to one of the longitudinal beams 20x of the structure 16, for example by means of a plurality of screws 32. Each of the first 24y-1 and second 24y-2 transverse edge is fixed to one of the transverse beams 20y of the structure 16, for example by means of a plurality of screws 32.

[0070] As can be seen in particular in Figure 1, each of the first 24x-1 and second 24x-2 longitudinal edge of the or of each second wall 24 is in contact with one of the first longitudinal edge 22x-1 and second longitudinal edge 22x-2 of the or one of the first walls 22.

[0071] The second wall 24 includes at least one first locking element 40 mechanically blocking the first wall 22.

[0072] In particular, in the illustrated embodiment, each of the second walls 24 comprises two first locking elements 40 mechanically blocking each of the first two walls 22 respectively.

[0073] For example, the first locking element 40 is a rim 42 extending in projection along the vertical axis Z from one of the first 24x-1 and the second 24x-2 longitudinal edge of the second wall 24 and partially covering the corresponding first wall 22, and in particular the first longitudinal edge 22x-1 of said first wall 22.

[0074] More specifically, the rim 42 covers that of the first longitudinal edge 22x-1 and the second longitudinal edge 22x-2 of said first wall 22 in contact with the longitudinal edge 24x-1, 24x-2 of the second wall 24 from which the rim 42 extends in projection.

[0075] Preferably, as can be seen in Figure 3, each rim 42 covers the clearance 34x of the associated longitudinal edge 22x-1, 22x-2 of the corresponding first wall 22.

[0076] More specifically, each flange 42 covers the outer face of the clearance 34x of the corresponding longitudinal edge 22x-1, 22x-2 of the corresponding first wall 22, thus covering the heads of the corresponding screws 32. Each second wall 24 preferably includes a clearance 44y provided on at least one of the first transverse edge 24y-1 and the second transverse edge 24y-2, and in particular on the first transverse edge 24y-1 as can be seen in Figure 2.

[0077] More specifically, as can be seen in Figure 4, the thickness of the second wall 24 is reduced at the clearance 44y.

[0078] In the embodiment illustrated in the Figures, the second wall 24 also includes a fourth locking element 46, specifically configured to mechanically lock the fourth wall 28.

[0079] More specifically, the fourth locking element 46 of the second wall 24 is a lug 48, in particular extending in projection from the second transverse edge 24y-2 of the second wall 24.

[0080] As can be seen in Figure 4, the lug 48 has a hook shape, specifically a semi-circular cross-section in the XZ plane.

[0081] The third wall 26, for example, extends perpendicularly to the longitudinal axis X.

[0082] In a particular embodiment, the third wall 26 is a plate, in particular substantially rectangular.

[0083] More precisely, the third wall 26 extends, along the vertical axis Z, between a first transverse edge 26y-1 and a second transverse edge 26y-2 extending parallel to the transverse axis Y. The third wall 26 extends, along the transverse axis Y, between a first vertical edge 26z-1 and a second vertical edge 26z-2 each extending parallel to the vertical axis Z.

[0084] The third wall 26 is fixed to the structure 16, for example by screws 32.

[0085] For example, each of the first 26y-1 and second 26y-2 transverse edge is fixed to one of the transverse beams 20y of the structure 16, for example by means of a plurality of screws 32. Each of the first 26z-1 and second 26z-2 vertical edge is fixed to one of the vertical beams 20z of the structure 16, for example by means of a plurality of screws 32.

[0086] As can be seen in particular in Figure 1, each of the first 26y-1 and second 26y-2 transverse edge of the third wall 26 is for example in contact with one of the first transverse edge 24y-1 and second transverse edge 24y-2 of the or one of the second walls 24.

[0087] The third wall 26 includes at least one second locking element 50 mechanically blocking one or both of the second walls 24. In particular, in the illustrated embodiment, the third wall 26 includes two second locking elements 50 mechanically blocking each of the two second walls 24 respectively.

[0088] For example, the second locking element 50 is a rim 52 extending in projection along the longitudinal axis X of one of the first 26y-1 and the second 26y-2 transverse edge of the third wall 26 and partially covering the corresponding second wall 24, and in particular the corresponding transverse edge 24y-1, 24y-1 of said second wall 24.

[0089] More specifically, the rim 52 covers that of the first transverse edge 24y-1 and the second transverse edge 24y-2 of said second wall 24 in contact with the transverse edge 26y-1, 26y-2 of the third wall 26 from which the rim 52 extends in projection.

[0090] Preferably, as can be seen in Figure 4, each rim 52 covers the clearance 44y of the first transverse edge 24y-1 of the corresponding second wall 24.

[0091] More specifically, each rim 52 covers the outer face of the clearance 44y of the first transverse edge 26y-1 of the second wall 24, thus covering the heads of the corresponding screws 32.

[0092] As can be seen in particular in Figure 1, each of the first 26z-1 and second 26z-2 vertical edge of the third wall 26 is for example in contact with one of the first vertical edge 22z-1 and second vertical edge 22z-2 of the or one of the first walls 22.

[0093] Advantageously, the third wall 26 also includes at least one third locking element 54 mechanically blocking the first wall or one of the first walls 22.

[0094] In particular, in the illustrated embodiment, the third wall 26 comprises two third locking elements 54 mechanically blocking each of the first two walls 22 respectively.

[0095] For example, the third locking element 54 is a rim 56 extending in projection along the transverse axis Y of one of the first 26z-1 and the second 26z-2 vertical edge of the third wall 26 and partially covering the corresponding first wall 22, and in particular the corresponding vertical edge 22z-1, 22z-2 of said first wall 22.

[0096] More specifically, each rim 56 covers that of the first vertical edge 22z-1 and the second vertical edge 22z-2 of said first wall 22 in contact with the vertical edge 26z-1, 26z-2 of the third wall 26 from which the rim 56 extends in projection.

[0097] Preferably, as can be seen in Figure 4, each flange 56 covers the clearance 34z of the first vertical edge 22z-1 of the corresponding first wall 22. More precisely, each flange 56 covers the outer face of the clearance 34z of the first vertical edge 22z-1 of the first wall 22, thus covering the heads of the corresponding screws 32.

[0098] The fourth wall 28, for example, extends perpendicularly to the longitudinal axis

[0099] X, and in particular with regard to the third wall 26.

[0100] In a particular embodiment, the fourth wall 28 is a plate, in particular substantially rectangular.

[0101] More precisely, the fourth wall 28 extends, along the vertical axis Z, between a first transverse edge 28Y-1 and a second transverse edge 28Y-2, each extending parallel to the transverse axis Y. The fourth wall 28 extends, along the transverse axis

[0102] Y, between a first vertical edge 28Z-1 and a second vertical edge 28Z-2, each extending parallel to the vertical axis Z.

[0103] The fourth wall 28 is fixed to the structure 16, for example by screws 32.

[0104] For example, each of the first 28Y-1 and second 28Y-2 transverse edge of the fourth wall 28 is fixed to one of the transverse beams 20y of the structure 16, for example by means of a plurality of screws 32. Each of the first 28Z-1 and second 28Z-2 vertical edge of the fourth wall 28 is fixed to one of the vertical beams 20z of the structure 16, for example by means of a plurality of screws 32.

[0105] As can be seen in particular in Figure 1, each of the first 28Z-1 and second 28Z-2 vertical edge of the fourth wall 28 is for example in contact with one of the first vertical edge 22z-1 and second vertical edge 22z-2 of the or one of the first walls 22.

[0106] In particular, in the embodiment illustrated in the Figures, the fourth wall 28 is mechanically blocked at least by a fourth locking element 36 of one of the first walls 22, and in particular by the fourth locking element 36 of each of the first two walls 22.

[0107] More specifically, at least one of the first 28Z-1 and the second 28Z-2 vertical edge of the fourth wall 28, and preferably both, comprise a bead 58z extending in projection from the corresponding vertical edge, and in particular from its inner face.

[0108] The lug 38 of the fourth locking element 36 of the corresponding first wall 22 is housed around the corresponding bead 58z.

[0109] As can be seen in particular in Figure 1, each of the first 28Y-1 and second 28Y-2 transverse edge of the fourth wall 28 is for example in contact with one of the first transverse edge 24y-1 and second transverse edge 24y Z-2 of the one or one of the second walls 24. In particular, in the embodiment illustrated in the Figures, the fourth wall 28 is mechanically blocked at least by the fourth locking element 46 of one of the second walls 24, and in particular by the fourth locking element 46 of each of the two second walls 24.

[0110] More specifically, at least one of the first 28Y-1 and the second 28Y-2 transverse edge of the fourth wall 28, and preferably both, comprise a bulge 58y extending in projection from the corresponding transverse edge, and in particular from its inner face.

[0111] The lug 48 of the fourth locking element 46 of the corresponding second wall 28 is housed around the corresponding bead 58y.

[0112] Advantageously, the opening detection mechanism 15 includes a detection element 60 configured to detect the dismantling of the third wall 26.

[0113] Preferably, the opening detection mechanism 15 does not include a detection element configured to detect the dismantling of the first 22, second 24 and fourth 28 walls.

[0114] In other words, the opening detection mechanism 15 is configured to detect only the dismantling of the third wall 26.

[0115] The detection element 60 is for example a switch whose opening and closing are linked to the fixing or not of the third wall 26 on the structure 16.

[0116] A method for mounting the housing 12 as described above and in the particular embodiment illustrated in the figures will now be described.

[0117] Structure 16 is provided first.

[0118] In step a), the fourth wall 28 is mounted on the structure 16.

[0119] For example, each of the first 28Y-1 and second 28Y-2 transverse edge of the fourth wall 28 is fixed to one of the transverse beams 20y of the structure 16, for example by means of a plurality of screws 32. Each of the first 28Z-1 and second 28Z-2 vertical edge of the fourth wall 28 is fixed to one of the vertical beams 20z of the structure 16, for example by means of a plurality of screws 32.

[0120] Next, in a step b) of assembly, each of the first walls 22 is mounted on the structure 16.

[0121] More specifically, in an embodiment illustrated in Figure 2, the lug 38 of each first wall 22 is first inserted around the corresponding bead 58z of the fourth wall 28.

[0122] By pivoting the lug 38 around the corresponding bead 58z, the first wall 22 is then preferably positioned against the structure 16. In particular, in this position, the fourth wall 28 is mechanically blocked by each of the first walls 22, in particular by the fourth locking element 36 of the first walls 22.

[0123] The fourth wall 28 is subsequently fixed to the structure 16.

[0124] For example, each of the first 22x-1 and second 22x-2 longitudinal edge is fixed to one of the longitudinal beams 20x of the structure 16, for example by means of a plurality of screws 32. Each of the first 22z-1 and second 22z-2 vertical edge is fixed to one of the vertical beams 20z of the structure 16, for example by means of a plurality of screws 32.

[0125] Next, in a step c) of assembly, each of the second walls 24 is mounted on the structure 16.

[0126] More specifically, in an embodiment illustrated in Figure 2, the lug 48 of each of the second walls 24 is first inserted around the corresponding bead 58y of the fourth wall 28.

[0127] By pivoting the lug 48 around the corresponding bead 58y, each second wall 24 is then preferably positioned against the structure 16. The edges 52 of each second wall 24 thus come to cover the corresponding longitudinal edges 22x-1, 22x-2 of each first wall 22.

[0128] In particular, in this position, the fourth wall 28 is mechanically blocked also by each of the second walls 24, in particular by the fourth locking element 46 of the second walls 24.

[0129] Similarly, each first wall 22 is advantageously mechanically blocked by each of the second walls 24, in particular by the first locking element 50 of the second walls 24.

[0130] Each second wall 24 is then fixed to the structure 16.

[0131] For example, each of the first 24x-1 and second 24x-2 longitudinal edge is fixed to one of the longitudinal beams 20x of the structure 16, for example by means of a plurality of screws 32. Each of the first 24y-1 and second 24y-2 transverse edge is fixed to one of the transverse beams 20y of the structure 16, for example by means of a plurality of screws 32.

[0132] Subsequently, in a step d) of assembly, the third wall 26 is mounted on the structure 16.

[0133] In particular, the third wall 26 is preferably positioned against the structure. The edges 52 of the third wall 26 thus cover the corresponding vertical edges 22z-1, 22z-2 of each first wall 22 and the corresponding transverse edges 24y-1, 24y-2 of each second wall 24.

[0134] In particular, in this position, each first wall 22 is mechanically blocked by the third wall 26, in particular by the third locking elements 54.

[0135] Similarly, each second wall 24 is mechanically blocked by the third wall 26, in particular by the second locking elements 50.

[0136] The third wall 26 is then fixed to the structure 16.

[0137] For example, each of the first 26y-1 and second 26y-2 transverse edge is fixed to one of the transverse beams 20y of the structure 16, for example by means of a plurality of screws 32. Each of the first 26z-1 and second 26z-2 vertical edge is fixed to one of the vertical beams 20z of the structure 16, for example by means of a plurality of screws 32.

[0138] Disassembly of such a 12-unit housing is advantageously carried out by the reverse process to that of assembly as described above.

[0139] In a first step a), the third wall 26 is dismantled from the structure 16, in particular by unscrewing the corresponding screws 32.

[0140] Indeed, since the fourth wall 28 is mechanically blocked by the first 22 and second 24 walls which are themselves blocked by the third wall 26, it is only possible to dismantle the third wall 26 first.

[0141] In a second step b), each second wall 24 is removed from the structure 16, in particular by unscrewing the corresponding screws 32.

[0142] Indeed, since the fourth wall 28 is mechanically blocked by the first 22 and second 24 walls and each first wall 22 is blocked by the second walls 24, it is only possible to dismantle the second walls 24 in the second stage.

[0143] In a step c), each first wall 22 is dismantled from the structure 16, in particular by unscrewing the corresponding screws 32.

[0144] Indeed, since the fourth wall 28 is mechanically blocked by the first walls 22, it is only possible to dismantle the first walls 22 in the third step.

[0145] In a final step (d), the fourth wall 28 is removed from the structure 16, notably by unscrewing the corresponding screws 32. Such a housing 12 is particularly advantageous.

[0146] Indeed, as explained above, due to the mechanical locking elements 36, 40, 46, 50, 54, the housing 12 can only be disassembled according to a precise order of steps.

[0147] Dismantling is therefore more complicated, which strengthens the protection against intrusion of equipment 10.

[0148] In particular, it is only possible to dismantle the third wall 26 first.

[0149] Thus, only one detection element 60 is required, which greatly simplifies the opening detection mechanism 15.

[0150] In addition, the locking elements 36, 40, 46, 50, 54 being mechanical locking elements, these are inexpensive to implement and do not generate additional electrical consumption.

[0151] In another embodiment of the invention (not illustrated), the housing 12 does not include a fourth wall 28, nor fourth locking elements 36, 46.

[0152] In this embodiment, the housing 12 comprises two third walls 26 facing each other.

[0153] In this embodiment, the detection mechanism 15 includes in particular two detection elements 60, one for each third wall 26.
