Description

TECHNICAL FIELD

[0001] The present invention relates to the field of systems for fastening a device on a support. BACKGROUND

[0002] Certain devices, in particular telecommunication modules for increasing the power of a signal, are designed to be fastened on a support by the user who has just acquired the device.

[0003] For example, there are 5G amplifiers ("booster") for improving the coverage of 5G networks. The user who has such a device needs to fasten the device on any suitable outdoor support, such as a column, a flagpole, a drainpipe, a balcony railing, etc., by himself.

[0004] The device therefore needs to be provided with a fastener system that is easy to use, which does not require the use of tools, and which enables anyone, in particular those with limited DIY skills, to effectively fasten the device on its support.

[0005] Since the support to be used can be of various shapes and various sizes, such a fastener system generally comprises a strap which the user places around the support and tightens.

[0006] The tightening force needs to be applied properly to guarantee a correct and durable fastening.

[0007] Clamping systems are known which guarantee a support under tension.

[0008] For example, toggle clamps are used to provide locking when passing through the balanced position (position of alignment of the articulation points). However, toggle clamps do not have much adjustment margin, so the user must be able to assess whether the clamping force is sufficient.

[0009] Metal clamping systems for fastening outdoor 5G modules on a support are also known. This metal clamping system can be adjusted roughly beforehand, then pressure is applied by means of a wing screw, but the pressure applied depends largely on the tightening force applied by the user. Again, the user needs to be able to assess whether the tightening force is sufficient.

[0010] The quality of the fastening therefore depends on the user's ability in this respect. This is problematic because the user is not a professional and generally has limited mechanical or DIY skills. As a result, it often happens that the device is not fastened well, or even damaged due to improper fastening. SUMMARY

[0011] The aim of the present invention is to provide a fastener system which enables a device to be fastened on a support, which is simple to use, does not require the use of tools, and which enables a proper tightening force to be obtained which is sufficient and independent of the user.

[0012] To achieve this object, there is provided a fastener system arranged to fasten a piece of equipment on a support, the system comprising:

[0013] a strap for going around the support and holding the fastener system on the support;

[0014] elastic means and mechanical abutment means;

[0015] adjustment means for adjusting the length of the strap;

[0016] at least one bearing surface;

[0017] the fastener system being arranged in such a way that, when the bearing surface is positioned against the support and the strap is going around the support, the length of the strap is adjusted to the size of the support by the adjustment means, then, in response to a manual pulling action on the first end of the strap, a tension is created in the strap for tightening the strap around the support by the strap acting on the first end of the elastic means, which then undergoes elongation, wherein the mechanical abutment means limit the elongation of the elastic means so as to impart a predetermined value of tension.

[0018] The fastener system of the invention does not require any tools and its use is very simple: positioning the fastener system on the support, going around the support with the strap and pulling the first end of the strap is enough.

[0019] The elastic means, whose elongation is then limited by the abutment means, are then used to ensure that the clamping is applied with a calibrated, repeatable and independent of any assessment by the user tension: the clamping force depends on the elongation of the elastic means and not on the user's action. The tightening can be controlled regardless of the position, orientation, size and shape of the support. The invention offers great latitude in adjusting the length of the strap while guaranteeing the tensioning of the strap without ambiguity (ambiguity).

[0020] There is also provided a fastener system as described above, further comprising opening and locking means arranged to respond to an opening manual action by opening the fastener system and thus enabling the positioning of the strap around the support and to a locking manual action by reclosing and locking the fastener system.

[0021] There is also provided a fastener system as described above, wherein the adjustment means and the opening and locking means are combined in a single module.

[0022] There is also provided a fastener system as described above, wherein the module is an adjustable clamp.

[0023] Also provided is a fastener system as described above, the fastener system comprising a slot of at least one of the support surfaces, the slot defining two different support portions of said support surface, the strap being passable through the slot between said support portions depending on the size of the support.

[0024] Also provided is a fastener system as described above, the fastener system having two support surfaces forming the two plates and a positioning mount with two side surfaces to which the plates are fastened and between which the plates are fastened.

[0025] Also provided is a fastener system as described above, wherein the support surfaces are perpendicular to each other.

[0026] Also provided is a fastener system as described above, wherein the elastic means is positioned at least partly between the positioning mount and the piece of equipment.

[0027] Also provided is a fastener system as described above, wherein each support surface comprises a non-slip mat.

[0029] Also provided is a fastener system as described above, wherein the second end of the strap is connected to the first end of the elastic means.

[0030] Also provided is a fastener system as described above, wherein the elastic means comprises a spring.

[0031] Also provided is a fastener system as described above, wherein the elastic means consists of a plurality of different elastic sub-elements.

[0032] Also provided is a fastener system as described above, the fastener system further comprising a swivel device arranged such that the piece of equipment can be swiveled to a predefined orientation regardless of the orientation of the support.

[0033] Also provided is a fastener system as described above, the swivel device being arranged positioned between the piece of equipment and the positioning mount.

[0034] Also provided is a fastener system as described above, the fastener system further comprising a deflection roller via which the strap passes.

[0035] Also provided is a fastener system as described above, wherein the strap has a static friction coefficient on the support of less than 0.2.

[0036] There is also provided an equipment assembly comprising both a piece of equipment as described above and a fastener system.

[0040] wrapping the strap around the support;

[0041] pulling the first end of the strap until the elastic means abuts.

[0042] The application can be better understood from the following description of specific, non-limiting embodiments thereof. BRIEF DESCRIPTION OF DRAWINGS

[0051] With reference to Figures 1 to 3 The fastener support 1 in the first embodiment of the application is used to fasten a piece of equipment 2 to a support 3.

[0052] In this example, the piece of equipment 2 is a telecommunication module, for example a 5G amplifier. In this example, the piece of equipment 2 is intended to be positioned outdoors.

[0053] In this example, the support 3 is a horizontal support, in the form of a circular cross-section tube. For example, the support 3 can be a balcony railing. For example, the diameter of the cross-section of the support 3 can be equal to 10 centimeters (cm). In other examples, the support 3 can be a vertical support, or the support 3 can be a support located in a plane having any orientation.

[0054] In this example, the piece of equipment 2 has a casing 4, which is generally in the form of a rectangular box with rounded corners. Of course, the application can be applied regardless of the shape of the casing, so the shape of the casing can be different, for example, it can be frustoconical.

[0055] The preferred operating position of the equipment 2 corresponds to Figures 1 to 3 the vertical position and orientation shown.

[0056] The casing 4 of the equipment 2 has a top face 5, a bottom face 6, two side faces 7, a front face 8 and a rear face 9. Thus, the terms "top", "bottom", "front" and "rear" correspond to the equipment 2 arranged in its preferred operating position.

[0057] The fastener system 1 protrudes from the rear face 9 of the casing 4 of the equipment 2.

[0058] The fastener system 1 first comprises a cylindrical base 10 having an axis X perpendicular to the rear face 9 of the casing 4 of the equipment 2. The base 10 protrudes from said rear face 9. The base 10 comprises an external face 11. In another example, the base 10 can be polygonal in shape.

[0059] The base 10 optionally incorporates a swivel device 12 for swiveling the equipment 2, so that the equipment 2 can be manually swiveled so that it can be swiveled to any predefined orientation regardless of the orientation of the support 3. In this example, the predefined orientation corresponds to the preferred operating position of the equipment 2.

[0060] The swivel device 12 comprises a stationary part, which is stationary with respect to the rest of the fastener system 1, and a rotating part, which is rotatable about the axis X with respect to the stationary part, which occupies a fixed position with respect to the casing 4 of the equipment 2.

[0061] The manual action consists in exerting a pressure on the rotating part and thus on the device 2, for unlocking the swivel device 12 (this unlocking can alternatively be performed by exerting a pressure on the stationary part and thus on the fastener system). The rotating part can then be turned manually by the user in order to swivel the device 2 relative to the fastener system 1, thus imparting a predefined orientation thereto. When the pressure is released, the swivel device 12 locks and the rotating part can no longer be turned (unless pressure is again exerted on the rear of the fastener system 1).

[0062] The swivel device 12 also has reference markings 13 on the rear face 9 of the housing 4 of the device 2, for designating the different possible orientations of the device 2.

[0063] The swivel device 12 thus makes it possible to compensate for any slope that can exist with the support 3, so as to maintain the device 2 in the recommended orientation for correct operation. This orientation is preferably, but not necessarily, provided to the device 2 before the fastener system 1 is installed on the support 3.

[0064] The fastener system 1 also has a positioning mount 14 that projects from the external face 11 of the base 10. The optional swivel device 12 is thus positioned between the device 2 and the positioning mount 14. The positioning mount 14 is constrained to turn with the stationary part of the swivel device 12.

[0065] The positioning mount 14 comprises a fastener holder 15 that has two side faces 16 that project perpendicularly from the external face 11 of the base 10.

[0066] An angle bracket 17 forms a transverse stiffener for the positioning side faces 16.

[0067] The positioning mount 14 has a first plate 18 that lies in a first plane P1 that is perpendicular to the rear face 9 of the housing 4 of the device 2, and a second plate 19 that lies in a second plane P2 that is perpendicular to the first plane P1 and thus parallel to the rear face 9 of the housing 4.

[0068] The first plate 18 and the second plate 19 extend between the side faces 16 of the fastener holder 15, and they are fastened to said side faces 16.

[0069] The first plate 18 has a bottom face on which a first bearing surface 20 is formed. The second plate 19 has a rear face on which a second bearing surface 21 is formed.

[0070] The positioning mount 14 also has a strut 22. The strut 22 is formed by a plate extending perpendicularly from a front face of the second plate 19 (opposite the second bearing surface 21) and serves to fasten the positioning mount 14 to the outer face 11 of the base 10.

[0071] In an implementation, a first slot 24 of rectangular shape is formed in the first plate 18. The first slot 24 extends from a central portion of an edge of the first plate 18.

[0072] The first slot 24 defines a first bearing portion 25 and a second bearing portion 26 of the first bearing surface 20, these portions being on opposite sides of the first slot 24.

[0073] In an implementation, a second slot 27 of rectangular shape is formed in the second plate 19. The second slot 27 defines a longitudinal cavity in the mount 14. The second slot 27 extends in a central portion of the second plate 19, perpendicularly to the first plane PI. The second slot 27 defines a first bearing portion 28 and a second bearing portion 29 of the second bearing surface 21, these portions being on opposite sides of the second slot 27.

[0074] The first slot 24 and the second slot 27 enable the positioning mount 14 to be compatible with supports 3 having a wide range of dimensions. Different dimensions in this wide range of dimensions cause different deflections of the two strands of the strip 35, justifying the presence of the first slot 24 and the second slot 27.

[0075] In this example, each bearing surface 20, 21 has a respective pad fastened (for example, by adhesive, welding, etc.) on the corresponding plate. The pads serve to avoid damaging the support 3 (for example, by scratching). It should be observed that each pad and the associated plate (or even the entire mount) can form a single component.

[0076] The fastener system 1 also has a first anchoring point 30 and a second anchoring point 31, located in a fixed position relative to the positioning mount 14, and therefore relative to the bearing surfaces 20 and 21, and therefore also relative to the housing 4 of the device 2 (at least when the swivel device 12 is locked). In this example, the first anchoring point 30 and the second anchoring point 31 are positioned between the second plate 19 and the outer face 11 of the base 10.

[0077] Each anchoring point 30, 31 comprises a respective pin fastened to the fastener support 15, each end of said pin being fastened to a different one of the side surfaces 16. The fastener system 1 also has a deflection roller 33 mounted to rotate about an axis parallel to the pins of the anchoring points, or comprising a smooth material with little adhesion. The deflection roller 33 is positioned flush with the top portion of the outer face 11 of the base 10. Each end of the deflection roller 33 is fastened to a separate one of the side surfaces 16.

[0078] The fastener system 1 also has a main strip 35 for passing around the support 3 and for retaining the fastener system on the support 3, thereby retaining the device 2.

[0079] The main strip 35 has a first end 36 and a second end 37, in this example the second end 37 being connected to the first anchoring point 30. More precisely, the second end 37 of the strip 35 passes around the pin of the first anchoring point 30, then folds back and is fixed to the rest of the strip 35 (for example by adhesive, welding, stitching, etc.).

[0080] It can be seen that when the strip 35 passes around the support, and depending on the dimensions of said support 3, it can pass through the first slot 24 and / or the second slot 27 (assuming they exist).

[0081] The fastener system 1 also has an adjustment device 38 for adjusting the length of the strip, and an opening and unlocking device 39.

[0082] The adjustment device 38 makes it possible to manually adjust the length of the strip 35 around the support 3. The adjustment device 38 is a non-return device. It can be released by a simple manual operation performed by the user.

[0083] In response to an opening manual action, the opening and locking device 39 serves to open the fastener system 1 and thus to position the main strip 35 around the support 3. In response to a locking manual action, the opening and locking device 39 also serves to reclose and lock the fastener system 1.

[0084] In this example, the adjustment device 38 and the opening and locking device 39 are combined in the same module, specifically an adjustable clip 40. The adjustable clip 40 comprises a male portion 41 and a female portion 42.

[0085] The male portion 41 comprises a male resilient engagement mechanism with three prongs, including two outer prongs 43 each provided at its free end with an outwardly directed hook, and two openings 44.

[0086] The female portion 42 comprises a female resilient engagement mechanism complementary to the male resilient engagement mechanism, and an opening 45.

[0087] The fastener system 1 also has a secondary strap 46.

[0088] The secondary strap 46 has a first end connected (by passing through the opening 45) to the concave portion 42 of the adjustable clamp 40.

[0089] The secondary strap 46 passes behind the deflection roller 33 and thus has a first portion parallel to the rear face 9 of the housing 4 and a second portion extending in the same direction as the main strap 35.

[0090] The first end 36 of the main strap 35 passes through one of the openings 44 in the convex portion 41 of the adjustable clamp 40 and then through the other, making it possible to adjust the length of the main strap 35 (or rather the length of the portion of the main strap 35 that clamps the support 3) by pulling on its first end 36.

[0091] The fastener system 1 also has elastic means, in particular a metal traction spring 50.

[0092] The first end of the spring 50 is connected to the adjustment means 38 and / or to the opening and locking means 39. In this example, the first end of the spring 50 is connected to the second end of the secondary strap 46 via a clasp 51 (and thus to the adjustable clamp 40 via the clasp 51 and the secondary strap 46).

[0093] The second end of the spring 50 is connected to the second anchoring point 31.

[0094] The spring 50 is positioned between the second plate 19 of the positioning mount 14 and the swivel means 12. The spring 50 is located between the two lateral faces 16 of the fastener support 15 so as to be very close to the outer face 11 of the base 10. Positioning the spring in this way serves to make the fastener system 1 more compact.

[0095] The spring 50 extends and elongates along a direction perpendicular to the first plane P1 and parallel to the second plane p2. Of course, this configuration is not essential.

[0096] Advantageously, the spring 50 is not too stiff so as to make the means sufficiently precise.

[0097] It should be recalled that for a linear spring:

[0098] K = F / A;

[0099] where K is the stiffness (in newtons per millimeter (N / mm)), F is the force (in newtons (N)) and A is the elongation (in millimeters, mm).

[0100] Advantageously, the stiffness of the spring is in the range 1 N / mm to 2.5 N / mm.

[0101] For a torsion spring, the following applies:

[0102] K = C / 0;

[0103] where K is the stiffness (in units of Newton-meters per radian (N.m / rad)), C is the torque (in units of N.m), and 0 is the angle between the ends of the spring (in units of radians).

[0104] In this example, the (linear) spring 50 is 30 mm long (when not elongated), and it can be elongated by 30 mm; so that its elongation length is 60 mm. It creates a tension of 50 N in the strap 35, giving a stiffness of 1.66 N / mm.

[0105] The fastener system 1 also has a mechanical abutment 52 that protrudes from the top portion of the external face 11 of the base 10 and extends below the deflection roller 33. The abutment 52 is located in a position facing the first end of the spring 50.

[0106] The way the fastener system 1 operates is described below.

[0107] The user exerts an opening manual action on the opening and locking device 39 in order to open the fastener system 1. The opening manual action simply consists in pressing the external prong 43 of the protruding portion 41 of the adjustable clip 40 and moving said protruding portion 41 away from the recessed portion 42.

[0108] The user then presents the positioning mount 14 against the support 3. The first bearing surface 20 and the second bearing surface 21 are pressed against the support 3.

[0109] The user winds the main strap 35 around the support 3 (around the support 3), then exerts a locking manual action on the opening and locking device 39 in order to close and lock the fastener system 1. The locking manual action simply consists in engaging the protruding portion 41 of the adjustable clip 40 in the recessed portion 42.

[0110] The user then exerts a pulling manual action on the first end 36 of the strap 35 (similar to pulling on the shoulder strap of a backpack).

[0111] The adjustment device 38 thus adjusts the length of the strap 35 to match the size of the support 3, then the strap 35 acts on the first end of the spring 50 via the adjustable clip 40, the secondary strap 46, the deflection roller 33 and the clasp 51, causing the spring 50 to elongate and create a strap tension for tightening it around the support 3.

[0112] The mechanical abutment 52 limits the elongation of the spring 50 so as to impart a predetermined value on the tensioning force and therefore on the tightening force. This tightening force depends on the elongation rate of the spring 50, which is predefined. When the first end of the spring 50 abuts, it cannot be pulled further.

[0113] The strip 35 is thus under tension, the spring 50 is at its maximum elongation of known length, and therefore the tension is known, well controlled and repeatable.

[0114] The clamping is thus subjected to a tension that is calibrated, repeatable and independent of any user's assessment.

[0115] When the strip is placed under tension, the assembly of the device, i.e. this piece of equipment 2 together with the fastener system 1, needs to be held with the other hand to prevent it from turning around the support 3.

[0116] When the first slot 24 in the first plate 18 and the second slot 27 in the second plate 19 of the positioning mount 14 are present, it should be observed that the strip 35 that passes around the support 3 passes through the first slot 24 and therefore between the first bearing portion 25 and the second bearing portion 26 of the first bearing surface 20 and also through the second slot 27 between the first bearing portion 28 and the second bearing portion 29 of the second bearing surface 21.

[0117] The strip 35 is thus under tension, the spring 50 is at its maximum elongation of known length, and therefore the tension is known, well controlled and repeatable.

[0118] The traction of the strip 35 thus exerts between the first bearing portion 25 and the second bearing portion 26 of the first bearing surface 20 and therefore pushes the first bearing portion 25 and the second bearing portion 26 against the support 3, obtaining an equivalent share of the bearing force against the bearing portions 25 and 26. Likewise, the traction of the strip 35 between the first bearing portion 28 and the second bearing portion 29 of the second bearing surface 21 serves to obtain an equivalent share of the bearing force against the bearing portions 28 and 29. This increases the lateral stability of the fastener system 1 and therefore of the equipment 2 on the support 3.

[0119] In addition, the first slot 24 and the second slot 27 allow the strip 35 to deform freely when it is tightened. The strip can thus be effectively tightened around supports of different shapes, presenting circular, square, rectangular, prismatic cross sections, etc., and of different sizes.

[0120] It should be observed that the strip 35 is advantageously a flexible but not stretchable strip, to avoid altering the deadweight rating of the spring 50.

[0121] Likewise, the strip 35 is advantageously smooth so that the clamping tension is well distributed over the entire surface area of the strip 35 and of the support 3.

[0122] The strip 35 should therefore be made of a material with low adhesion.

[0123] The static friction coefficient of the strip 35 on the support is therefore preferably lower than a predetermined threshold value (which depends on the material of the support: plastic material, zinc, aluminum alloy, painted steel, etc.). Advantageously, the static friction coefficient of the strip 35 on the support is less than 0.2.

[0124] For a support made of smooth polyvinyl chloride (PVC), the predetermined threshold value is equal to 0.15.

[0125] It should be observed that, in order to obtain this quality of low adhesion, the strip can also be treated on the surface or in depth.

[0126] With reference to Figure 4 , a fastener system 101 for fastening a device 102 on a support 103 is described below in a second embodiment.

[0127] In this embodiment, the fastener system 101 does not comprise means for swiveling the device 102.

[0128] In this example, the second plate 119 of the positioning mount 114 is fastened directly on the rear face 109 of the housing 104 of the device 102.

[0129] The fastener system 101 has a first anchoring point 130 located at the bottom end of the rear face 109 of the housing 104 and a second anchoring point 131 located at the top end of the rear face 109 of the housing 104.

[0130] The second end 137 of the main strip 135 is connected to the first anchoring point 130 and the second end of the elastic means 150 is connected to the second anchoring point 131.

[0131] The first end of the elastic means 150 is connected to the opening and locking means 138 via a secondary strip 146 which, in this embodiment, does not pass behind the deflection roller.

[0132] The mechanical abutment 152 is positioned directly on the positioning mount 114. The mechanical abutment 152 projects from the top face of the first plate 118, while the first bearing surface 120 extends on the bottom face of said first plate 118. The mechanical abutment 152 is inclined upward and backward.

[0133] In this example, the adjustment means 138 and the opening and locking means 139 are two distinct elements.

[0134] With reference to Figure 5 , the fastener system 201 in the third embodiment is described below.

[0135] The fastener system 201 does not comprise means for swiveling the device 202.

[0136] The second plate 219 of the positioning mount 214 is fastened directly on the rear face 209 of the housing 204 of the device 202 by means of the strut 222.

[0137] The spring 250 is positioned (at least partially) between the rear face 209 of the housing 204 of the device 202 and the second plate 219.

[0138] The abutment 252 protrudes perpendicularly from the top portion of the rear face 209 of the housing 204 of the device 202.

[0139] The deflection roller 233 is positioned above the abutment 252 and the secondary strip 246 passes behind the deflection roller 233.

[0140] In Figure 5 , it can be seen that the positioning mount 214 enables the fastener system 201 (and thus the device 202) to be positioned on a support which can have various different shapes, in particular the shape of a circular cross-section tube (support 203) or a square cross-section tube (support 203').

[0141] The reference 235 corresponds to the shape taken by the primary strip during tightening when the support is circular in cross-section. The reference 235' corresponds to the shape taken by the primary strip during tightening when the support is square in cross-section.

[0142] It should be observed that, compared to Figure 4 , the repositioning of the spring 250 enables the fastener system 201 to be more compact and / or enables the stiffness of the spring 250 to be reduced.

[0143] With reference to Figure 6 , the fastener system 301 in the fourth embodiment is described below.

[0144] The fastener system 301 has a first anchoring point 330 and a second anchoring point 331, both of which are positioned flush with the top end of the rear face 309 of the housing 304 of the device 302.

[0145] The spring 350 is positioned in the vicinity of the rear face 309, above the positioning mount 314.

[0146] The fastener system 301 comprises a deflection roller 333.

[0147] The main strip 335 passes behind the deflection roller 333, loops around the support 303 and then passes through a first slot 324 formed in the first plate 318.

[0148] The second end 337 of the strip 336 is directly connected to a first end of a spring 350. A second end of the spring 350 is connected to the second anchoring point 331.

[0149] The abutment 352 protrudes perpendicularly from the rear face 309.

[0150] It should be observed that the position of the deflection roller 333, the position of the abutment 352 and the position of the right angle formed by the intersection between the first plate 318 and the second plate 319 in a direction parallel to the length of the housing 304 are more or less identical. The deflection roller 333 is located between the right angle and the device 302. The abutment 352 is slightly higher than the deflection roller 333.

[0151] The secondary strip 346 has a first end connected to the first anchoring point 330 and a second end connected to the opening and locking means 339.

[0152] It can be seen that, in particular thanks to the presence of the first and second slots, the positioning mount 314 is compatible with a wide range of dimensions of the support. In this example, the support 303 is in the form of a tube of circular cross-section and its diameter is less than the diameter of the tube in the above-mentioned figures. For example, the diameter of the cross-section of the support 303 can be equal to 3 centimetres.

[0153] The support can also be in the form of a tube of rectangular cross-section with a small width and length, the support 303'.

[0154] With reference to Figure 7 , a fastener system 401 in a fifth embodiment is described below.

[0155] This embodiment is very close to the embodiment of Figure 5 , except that the fastener system 401 comprises a swivelling device 412 for swivelling the device 402.

[0156] Furthermore, in this example, the mat 453 forming the bearing surface is a non-slip mat made of a material that prevents the bearing surface from slipping on the support. The adhesion coefficient of the material used to make the mat on the support is advantageously greater than 0.5.

[0157] The use of such mats is advantageous. These mats serve to limit the swivelling of the fastener system 401 around the support 403 (or the support 403') when tensioning the main strip 435 (or the main strip 435'). The fastener system 401 can then be mounted on the support without needing to hold the fastener system 401 (and / or the device 402) with the other hand to prevent it from swivelling around the support when pulling on the first end of the main strip to adjust its length and clamp it to the support.

[0158] Furthermore, as mentioned above, in this example, the device 402 is positioned outdoors and can be subject to various environmental constraints, in particular the wind which tends to loosen the fastener system. The non-slip mat 453 is used to prevent the fastener system 401 from loosening.

[0159] Of course, the application is not limited to the described embodiments, but covers any variants falling within the scope of the application as defined by the claims.

[0160] The elastic means is not necessarily a metal traction spring: any type of elastic means can be used. It can be a non-metallic spring, but also a compression spring, a torsion spring, a hairpin spring, etc. The elastic means can consist of an elastic ring (for example made of rubber), or even just an elastic band.

[0161] The elastic means can consist of a plurality of distinct elastic sub-elements, for example in parallel association. The maximum length of elongation of such elastic sub-elements is smaller compared to an elastic means comprising a single traction element. For example, the elastic means can comprise a plurality of short springs in parallel association, instead of a single spring of greater length. Such an elastic means has limited dimensions and serves to reduce the overall dimensions of the fastener system. The elastic sub-elements are not necessarily in parallel association, they can be in series association, in a "V" configuration, etc. or in a hybrid configuration.

[0162] The mechanical abutment is not necessarily a distinct mechanical element, but it can be one of the other elements of the system (for example one of the plates of the positioning mount, a deflection roller, an element of the housing of the device, etc.), or it can be incorporated in the spring.

[0163] The adjustment means and the opening and locking means can be incorporated in some other type of module. Thus, the adjustment means and the opening and locking means can constitute two distinct elements. For example, the adjustment means can be a cam buckle.

[0164] The fastener system can constitute a part of the device, or be added to the device and fastened to it.

[0165] The support surface(s) can be incorporated directly in the housing (without positioning mount). The support surface(s) can then optionally be shaped to support against a support having a particular shape.

[0166] The device can be any type of device: electronic or other device, telecommunication device or other device, wired or wireless device, etc. The device can be a 5G amplifier transmission module. In other examples, the device is a mode 3G / 4G transceiver, a Wi-Fi access point or extender, or a device combining various wireless communication technologies.
