DETAILED DESCRIPTION OF EMBODIMENT EXAMPLES

(11) A bracing device 100 according to the invention is intended to be used to secure a facing panel to the front of a structure, in particular for lining in front of a wall.

(12) According to one nonlimiting embodiment illustrated in FIG. 6E, a plurality of bracing devices 100 is secured to a wall M that is to be lined, an insulating filling G is speared onto or interposed between the bracing devices, and facing panels P are secured to the front of said bracing devices, covering the insulating filling.

(13) A bracing device 100 according to one embodiment of the invention is illustrated in FIGS. 1 to 5.

(14) At the very least, it is made up of a main body 10 designed to be secured to the wall M or to some other structure, and of a mounting plate 60 designed to be mounted at the front end 10a of the body 10 and intended to have a facing panel P bearing against it.

(15) The body 10 and the mounting plate 60 are made for example from a polymer material, which may or may not be reinforced, for example with a glass fiber reinforced polyamide (the reinforcement representing for example between 20 and 40% by mass) or from polypropylene.

(16) Throughout the present description, the rear of a component will be referred to as its side closest to the structure, and the front of the same component as its side closest to the facing panel or panels P, in the assembled position.

(17) In the example illustrated, the body 10 comprises: at its rear end 10b: a base 12 for securing to the wall M and equipped with means for securing the body 10 to the structure M that is to be lined at its front end 10a: a shank 20 to which the mounting plate 60 is secured.

(18) The means for securing the body 10 to the structure M that is to be lined here comprise a securing plate 14 provided with holes 16 for securing it using screws.

(19) Advantageously, the securing plate 14 has at least one oblong hole 16a, 16b allowing fine adjustment of the positioning of the securing base 12 on the wall M. In the example depicted in FIGS. 1 and 2, the securing plate comprises two oblong holes 16a, 16b, the longest dimensions of which are parallel to one another. Alternatively, the longest dimensions of the oblong holes may be perpendicular to one another in order to facilitate fine adjustment of the positioning of the base both vertically and horizontally.

(20) Advantageously, the securing plate 16 is also provided with slots 18a, 18b designed to collaborate by clip fastening with a profile section secured beforehand to the structure that is to be lined, and in particular designed to accept reentrant edges of said profile section. What is meant by a profile section is, in general, a metal profile section, preferably a C-section, applied to the structure that is to be lined with the back of the C facing toward the structure that is to be lined and the opening of the C facing toward the lining to be applied.

(21) The illustrated example of the securing plate 14 is not, however, limiting, and the means for securing the body 10 to the structure may adopt other forms, for example suited to being secured using nails.

(22) The shank 20 of the body, which shank is illustrated in greater detail in FIG. 4, extends along an axis X1 defining an axial direction of the bracing device 100.

(23) In an advantageous arrangement, it is configured to be able to pierce the insulating filling G or, where applicable, a damp-proof membrane attached in front of said insulating filling G, and for that purpose may have a tapering, preferably pointed tip 21.

(24) The shank 20 is also provided with means for securing to the mounting plate 60.

(25) In the example at its periphery it comprises, over at least a portion 22 situated at its front end, a plurality of ribs 24 referred to as primary ribs, in this instance uniformly spaced from one another, mutually parallel and orthogonal to the axial direction X.

(26) For example, the primary ribs 24 may be spaced at intervals with a fine pitch p, in particular comprised between 0.1 and 5 mm, in particular between 0.2 and 2 mm, and more particularly between 0.5 and 1.5 mm.

(27) Each rib 24 in this instance is truncated over two angular portions (referred to as truncated primary portions) 26a, 26b and is thus formed of two rib portions (referred to as non-truncated primary portions) 24a, 24b, of an angle of less than 90°, which are diametrically opposed.

(28) Stiffening ribs 28 may advantageously be provided to strengthen the shank 20 at each truncated primary angular portion.

(29) The mounting plate 60 will now be described in greater detail with reference to FIGS. 1, 2 and 5.

(30) Hereinafter, a central axis (in this instance an axis of symmetry) X2 of the mounting plate 60 is defined. In a direction parallel to this axis X2, the mounting plate 60 is delimited by a bearing face 62 intended to have the facing panel or panels P bearing against it, and by an opposite face 64 substantially parallel to said bearing face.

(31) In the standard setup (illustrated in FIGS. 1 and 2) the bearing face 62 of the mounting plate 60 is situated toward the front of the bracing device. The bearing face 62 is therefore considered as being the front face of the mounting plate 60, and the opposite face 64 as being its rear face.

(32) Once the mounting plate 60 is mounted on the shank 20, in the standard setup just as in the reverse setup, the axis X2 is coincident with the axis X1 corresponding to the axial direction X of the bracing device 100. Throughout the present description, an axial direction mentioned in connection with the mounting plate corresponds to the direction of the axis X2 and therefore to the axial direction X of the bracing device in the mounted position. A radial direction is orthogonal to this axial direction.

(33) In order to engage it on the shank 20 of the body 10, the mounting plate 60 has a central mounting opening 70, centered on the axis X2.

(34) In the example, this central mounting opening 70 is extended, beyond the rear face 64 of the mounting plate 60, by a cylindrical sleeve 72.

(35) In the detail shown in FIG. 5, it may be seen that several ribs 74, referred to as secondary ribs, project toward the inside of the mounting opening 70.

(36) These secondary ribs 74 are designed to collaborate with the primary ribs 24 of the shank 20 in order to block translational movement of the mounting plate 60 on the body 10 in the axial direction X.

(37) They are spaced uniformly from one another, are mutually parallel, and are orthogonal to the axis X2.

(38) The mounting plate 60 is mounted on the shank 20 via a system of the bayonet or quarter-turn type:

(39) For that, the secondary ribs 74 are truncated over two angular portions (referred to as truncated secondary portions) 76a, 76b, each secondary rib thus being formed of two non-truncated secondary angular portions 74a, 74b.

(40) The mounting plate 60 is engaged on the shank 20 by aligning the non-truncated secondary angular portions 74a, 74b with the truncated primary angular portions 26a, 26b, then by causing relative pivoting of the mounting plate 60 and the portion of shank 22 so as to bring the secondary ribs 74 into engagement with the primary ribs and thus block the axial movement of the mounting plate.

(41) Advantageously, the secondary ribs 74 are equipped with an end-of-travel limit stop 78 configured to block the rotation of the mounting plate 60 with respect to the portion of shank 22 in one direction of rotation about the axis X, by collaborating with a lateral edge of a primary rib 24 or with two parallel adjacent primary ribs 24.

(42) However, the abovementioned example is nonlimiting and the means for securing the mounting plate 60 on the body 10 may adopt any other suitable form that may or may not allow adjustment of the axial positioning of the mounting plate 60 on the body 10. Such means could, for example, be clip-fastening means, or else a continuous screw thread for mounting by screwing without blocking.

(43) The specific features of the mounting plate 60 that allow the sheet or sheets of facing to be secured firmly to its bearing face will now be described in greater detail.

(44) In an essential arrangement, the bearing face 62 of the mounting plate has at least one transverse dimension greater than or equal to 30 mm, preferably greater than or equal to 45 mm. What is meant by a transverse dimension is a dimension measured in a plane orthogonal to the axis X2 (or in other words to the axial direction X when the mounting plate 60 is secured to the front end 10a of the body 10). Giving the bearing face 62 of the mounting plate 60 a sufficient transverse dimension allows the facing panel P to be secured to said mounting plate 60 firmly enough to ensure good mechanical integrity of the assembly.

(45) A minimum transverse dimension of the mounting plate 60 is preferably greater than or equal to 30 mm, preferably greater than or equal to 45 mm. The maximum transverse dimension of the mounting plate 60 is preferably less than or equal to 600 mm, in particular less than or equal to 400 mm, and even less than or equal to 200 mm.

(46) In addition, the total surface area of the bearing face 62 is preferably greater than at least 900 mm.sup.2, preferably greater than 2025 mm.sup.2. What is meant here by the total surface area is the surface area of the envelope surface of the bearing face 62.

(47) In the example illustrated, the mounting plate 60 has an axial cross section that is circular overall, with a diameter D equal to 9 cm.

(48) By way of alternative, it could obviously be square, rectangular, hexagonal or octagonal or have any other suitable shape.

(49) It is advantageously equipped, at its periphery, with means for grasping making it easier to grasp and to mount on the body 10. These means for grasping may for example comprise grasping lugs 66a, 66b uniformly distributed on its circumference, preferably at least two diametrically opposed lugs.

(50) The bearing face 62 of the mounting plate 60 may be smooth or, according to an advantageous arrangement illustrated in FIG. 5, may be textured. What is meant by a “textured face” is that the face in question has a relief made up of a succession of peaks and of valleys. This relief may be periodic or random. The texturing of the surface may also exhibit a plurality of different reliefs, distributed uniformly or randomly.

(51) In any case, whether it is smooth or textured, the bearing face 62 remains planar overall. What is meant by a face that is “planar overall” is that the envelope surface of this face is substantially planar.

(52) In the example illustrated, the front face 62 of the mounting plate 60 has a plurality of continuous concentric ribs 80 centered on the axis X2. These ribs 80 all have the same, constant, height h, measured in the direction X2, typically comprised between 1 and 3 mm. The distance dl between two ribs 80, measured in a radial direction, is also comprised between 2 and 5 mm.

(53) The example illustrated is obviously nonlimiting: the ribs 80 could be discontinuous. They could form a different pattern, a honeycomb for example, or else a random pattern.

(54) The ribs 80 form catching means intended to engage with the means for securing of the facing panel.

(55) The texturing effectively gives any fixing screws of the facing panel P a better purchase or, in the case of securing by means of adhesive, increases the area of contact of the adhesive with the mounting plate 60.

(56) In a variant illustrated in FIG. 9, the front face 62 of the mounting plate 60 exhibits, in addition to the concentric ribs 80, radial ribs 81. These radial ribs 81, positioned between the concentric ribs 80, all have the same, constant, height h1 which is less than the height h of the concentric ribs 80. Such a configuration prevents the screw from causing the mounting plate to spin as the facing panel P is being screwed on, or prevents the screw from screwing in crooked.

(57) At certain special points, in particular around the windows or the doors, it is sometimes preferable to have a continuous support for the facing panels P in the form of metal profile sections as used in the systems of the prior art.

(58) In preparation for such a requirement, the mounting plate 60 may advantageously perform a dual function: on the one hand having facing panels P resting against it and, on the other hand, of supporting a framework element such as a metal profile section.

(59) To do that, in the example, the mounting plate 60 is designed to be secured to the body 10 reversibly and, on its opposite side to the bearing face 62, comprises means for connection to a profile section, in particular means for clipped slideway connection of the mounting plate to a profile section.

(60) The reversibility is made possible here through the fact that the primary ribs 24 and secondary ribs 74 are orthogonal to the axial direction X and can thus collaborate identically whether the mounting plate 60 is mounted in the standard setup or in the reverse setup (with the front face oriented toward the rear of the bracing device 100).

(61) In the example, the means for clipped slideway connection comprise two slots 82a, 82b designed to accept reentrant edges of the profile section in the manner of a clip.

(62) As illustrated in FIG. 2, the mounting plate 60 may advantageously be reinforced, on its opposite side to the bearing face 62, by stiffeners 84a, 84b which connect the rear face 64 to the cylindrical sleeve 72.

(63) The collaboration of the primary ribs 24 and secondary ribs 74 allows fine adjustment of the position of the mounting plate 60 in the axial direction. This fine adjustment makes it possible for example to compensate for certain irregularities in the surface of the structure M.

(64) In some cases, for example in renovation applications, these irregularities are far greater. In that case, it is advantageous for the bracing device to be provided with a mechanism for adjusting the length of the body 10 by intervals, in particular by relative sliding of the securing base 12 and of the shank 20.

(65) The shank 20 typically has a total length L1 comprised between 5 and 20 cm.

(66) For example, the length L of the body 10 may, by virtue of the adjusting mechanism, be comprised between 5 and 25 cm.

(67) The length is adjusted by relative sliding of the securing base 12 and of the shank 20 in the axial direction X, followed by the blocking of axial translation by relative rotation of the two components 12, 20.

(68) In the example, translational movement is blocked in one of several possible positions of adjustment, spaced at intervals at a coarse pitch P comprised for example between 0.5 and 5 cm, preferably between 0.5 and 2 cm, more preferably still, between 0.8 and 1.3 cm, for example equal to 1 cm, as described in greater detail later.

(69) In its section 30 situated to the rear of the ribbed portion of shank 22, the shank 20 has a constant-diameter circular cross section.

(70) At its periphery it is also equipped with a plurality of lugs 32 uniformly spaced by the pitch P.

(71) In the particular example depicted, the shank 20 in reality comprises two diametrically opposed rows of identical or similar lugs 32, which lugs are aligned axially and uniformly spaced by the pitch P (in this instance three lugs in each row).

(72) Between these two rows of lugs 32, the shank 20 also has two diametrically opposed grooves 34, each of them being straight and continuous as far as the rear end of the shank, and extending in the axial direction X1. Only one of these grooves 34 is visible in FIG. 4.

(73) As illustrated in FIG. 4, the shank 20 also comprises a plurality of grooves 36 extending in the one same circumferential direction from each axial groove 34. These grooves 36 referred to as circumferential grooves in this instance extend over just part of the circumference of the shank 20. They are mutually parallel and spaced apart by the pitch P, and are axially offset from the aforementioned lugs 32 by a distance for example equal to P/2 (in the example, one lug is respectively axially centered between two circumferential grooves 36).

(74) As illustrated in FIGS. 1, 2, 3A and 3B, the securing base 12 is equipped with an adjusting part 40 of tubular shape extending along an axis X3 and solidly attached to the means for securing to the structure that is to be lined, in this instance the securing mounting plate 14. The adjusting part 40 here forms a hollow tube designed to accept within it the shank 20, the axes X1 and X3 therefore being coincident. For that, it comprises a central open part 42 of circular internal cross section, of a diameter slightly greater than that of the shank 20, extended by two diametrically opposed housings 44a, 44b intended to accept the lugs 32 of the shank 20 in a first angular position.

(75) As illustrated in FIG. 1, the adjusting part 40 is equipped, on its central part 42, with a plurality of notches 46 which are aligned in the axial direction and spaced apart by the pitch P.

(76) More specifically, the adjusting part 40 here comprises two diametrically opposed rows of five notches 46 each.

(77) In the example, the notches 46 are open ended holes, so that the fitter can see the adjustment. However, in a variant, the notches 46 could be formed by non-penetrating recesses made on the internal wall of the adjusting part 40.

(78) At the same time, the adjusting part 40 exhibits (see FIG. 3B), in the vicinity of its front end, two diametrically opposed internal additional thicknesses 41a, 41b dimensioned to each side in one of the axial grooves 34 of the shank 20 when the shank 20 and the adjusting part 40 are in the first angular position.

(79) In the first position, the shank 20 is designed to slide axially in the adjusting part 40, so as to adjust the total length L of the body 10.

(80) A relative rotation of the shank 20 and of the securing base 12 is permitted when each lug 32 of the shank 20 situated inside the adjusting part 40 is positioned axially facing a notch 46 of this same part 40, and at the same time each internal additional thickness 41a, 41b of the adjusting part 40 is positioned axially facing one of the circumferential grooves 36 of the shank 20. The corresponding positions are referred to hereinafter as positions of adjustment.

(81) In these positions of adjustment, the shank 20 and the securing base 12 are able to pivot, in one direction of rotation, so as to cause the lugs 32 of the shank 20 to penetrate into the notches 46 of the adjusting part 40.

(82) As illustrated in FIG. 4, the shank 20 preferably has an upper safety portion 38 that has no circumferential grooves 36. In the example illustrated in FIG. 1, the first circumferential groove 36 is situated between the second and the third lug 32, counting from the rear end 20b of the shank 20. Thus, the pivoting toward the second angular position is permitted only when at least the first two lugs 32 have penetrated the adjusting part 40. These arrangements avoid the fitter fitting the shank 20 onto an insufficient number of lugs 32 for reacting the compressive/tensile forces and possibly the bending forces to which the bracing device 100 is subjected in operation.

(83) The securing base 12 and the shank 20 are held in position after the length L of the body 10 has been adjusted by virtue of means for blocking the rotation of the two elements in the second angular position.

(84) These blocking means here comprise mechanical means with end stops and, more particularly, clip-fastening means, which will be described in greater detail later.

(85) For the remainder of the present description, the notches that have a rotation blocking function are referred to as blocking notches 46a, and the notches that have exclusively a translation blocking function are referred to as intermediate notches 46b (see FIG. 3A).

(86) In general, any notch 46 forms a housing extending in a circumferential direction and having, in that direction, a first end 51 via which a lug 32 of the shank 20 moving away from the first angular position enters the notch, and a second end 52 toward which that same lug 32 heads during the rotation from the first to the second angular position.

(87) As illustrated in FIG. 3A, an intermediate notch 46b is generally delimited, in the axial direction, by two walls 53a, 53b orthogonal to the axis X2 and spaced apart by a distance equal to or very slightly greater than the length of a lug 32 measured in the axial direction.

(88) As illustrated in FIGS. 3A and 3B, a blocking notch 46a for its part is delimited by a fixed wall 53a and, in the example, by a clip-fastening tongue 54, which is secured by a proximal end 54a at the level of the first end 51 of the notch 46a and extends in a circumferential direction as far as its opposite distal end 54b at which it is free.

(89) An empty space 55 situated on the opposite side of the tongue 54 to the notch allows the tongue to move toward said side under the pressure exerted by the lug 32 moved in the notch during a rotation from the first to the second angular position.

(90) The tongue 54 furthermore has elasticity properties that allow it to return automatically to its initial position in which it forms a non-return end stop for the lug, once the second angular position has been reached.

(91) As illustrated in FIG. 3B, the clip-fastening tongue 54 defines with the wall opposite an engagement portion comprising a progressive narrowing 56a of minimal width less than the length of a lug 32 measured in the axial direction.

(92) Beyond this narrowing 56a, the engagement portion 56 is extended by a blocking portion 57 designed to receive the lug 32 once the second angular position has been reached.

(93) In the example, the tongue 54 is configured in such a way that a return to the first angular position is possible under the effect of a relative rotational movement of the shank 20 and of the securing base 40, or of the combined effect of a relative translational and rotational movement of the shank 20 and of the securing base 40.

(94) Advantageously, as illustrated in FIG. 1, only certain notches 46, generally those situated at the ends of the adjusting part 40, are equipped with clipping means. Thus, the force necessary for unclipping is not excessively great and the blocking is reversible. If the fitter makes a mistake in the adjusting of the length, he can, subsequently, undo the blocking easily and adjust the length again. The clip-fastening, through the noise that it makes, also allows the fitter to be sure that rotation is complete and that the shank is correctly fastened to the securing base.

(95) The successive steps of a method for lining according to the invention will now be described in connection with FIGS. 6A to 6E.

(96) FIG. 6A illustrates a masonry wall delimiting a room 90, and that is to be lined in order to improve the thermal insulation of said room. It will be noted that, while the embodiment example illustrated relates to a masonry wall, the invention is suitable for any type of wall (concrete, blockwork, bricks, wood, etc.).

(97) Brackets, a bottom bracket 91 and a top bracket 92, are first of all secured, generally using screws, to the floor and to the ceiling of the room respectively, at a given distance from the wall M that is dependent on the thickness of the insulating filling G intended for the lining. L-shaped brackets are enough in this instance to secure the facing panels, but these could also be replaced by U-section rails of the kind used in the metal frameworks of the prior art.

(98) Mid-way up the wall M a horizontal line 93 is drawn, marking the level at which the bracing devices 100 according to the invention are to be secured.

(99) In a second step illustrated in FIG. 6B, the bodies 10 of the bracing devices are secured, in this instance by screwing their securing plates 14 directly to the wall M, at the level of the horizontal line 93 drawn previously.

(100) The horizontal spacing between two bodies 10 is chosen to be short enough to ensure sufficient stiffness of the lining. This spacing might also be dependent on the width and mechanical performance of the facing panels.

(101) Typically, 1 facing device is fitted per square meter, on average, and away from the special points.

(102) In instances in which, as in the example illustrated, the length L of each body 10 is adjustable, this length will preferably be adjusted by the fitter beforehand, prior to securing the body to the wall M.

(103) In a third step illustrated in FIG. 6C, a spacer filling G is interposed between the bodies 10 of the bracing devices. This filling G generally consists of one or more layer(s) of thermal and/or acoustic insulation, for example mineral wool, notably glass wool or rockwool. By way of alternative, widths of insulation may also be speared onto the projecting shanks of the bracing devices.

(104) In addition, the lining may also comprise at least one damp-proof membrane fitted in front of the insulating filling. This damp-proof membrane may be speared onto the bodies of the bracing devices once the insulating filling has been fitted. In other instances, it may be integrated with said insulating filling (insulating panels covered on their front face with a damp-proof membrane).

(105) In a fourth step illustrated in FIG. 6D, the mounting plates 60 of the bracing devices are mounted and secured on the shanks 20, thus partially covering the insulating filling G. Where appropriate, those parts of the shanks 20 that protrude from the mounting plate 60 after mounting are cut off, for example using a grinder or cutting pliers.

(106) The alignment of the bearing faces 62 of the mounting plates 60 is verified using a level placed horizontally, resting against said bearing faces 62. For each bracing device 100, the axial position of the mounting plate 60 on its shank 20 can be adjusted, if necessary, using the quarter-turn system.

(107) In the same way, the alignment of each bearing face 62 of each mounting plate 60 with the front face of the top and bottom brackets 91, 92 is checked using a level placed vertically, resting against the bearing face 62 of the mounting plate 60 on the one hand, and against, on the other hand, the front faces of the bottom bracket 91 and of the top bracket 92 respectively. Once again, an adjustment is made if necessary.

(108) In a fourth step illustrated in FIGS. 6E and 6F, the facing panels P are pushed against the mounting plates 60 of the bracing devices 100 and then secured to said mounting plates.

(109) In the example illustrated, the facing panels are secured to the mounting plates 60 using screws: the bracing devices being secured to the wall that is to be lined approximately mid-way up this wall and spaced from one another by a distance equivalent to half the width of a sheet, each sheet is secured by at least two fixing points: one fixing point at the center (which can easily be determined because it is mid-way from the lateral edge of the sheet) and one fixing point near each lateral edge (except when this edge adjoins an end of the wall that is to be lined and therefore rests against the adjacent wall).

(110) As an alternative or in addition, the panels could also be secured by bonding, in particular using a liquid or pasty adhesive, for example as mastic, or by means of an adhesive element, of the film or tape type, in particular a double-sided sticky tape.

(111) A bracing device 200 according to the invention may also be used to create a dividing partition, formed of a first and of a second facing which are parallel.

(112) In that case, as illustrated in FIG. 7, the rear end 10b of the body 10 of the device 200 may be equipped with means for securing it to at least one panel P1 of the first facing and the mounting plate 60 of the device 200 is intended for securing a panel P2 of the second facing. Hereinafter, a primary panel is defined as being a panel belonging to the first facing of the partition and a secondary panel as being a panel belonging to the second facing.

(113) The means for securing to the primary panel P1, which are present at the rear end 10b of the body 10, may take the form of a second mounting plate 160 similar to the one described hereinabove, or in other words a mounting plate equipped with a face that is planar overall for the primary panel P1 to bear against (and which is therefore oriented toward the rear of the device), said bearing face having at least one transverse dimension greater than or equal to 30 mm, preferably greater than or equal to 45 mm. Advantageously, the second mounting plate 160 is of one piece with the body 10. In the case illustrated in which the body comprises a shank 20 extending in the axial direction X, at its front end 10a, and a securing base 12, the second mounting plate 160 is of one piece with said securing base 12.

(114) The structural features and dimensions described hereinabove in connection with the first mounting plate 60 apply in the same way to the second mounting plate 160. In particular, the minimum transverse dimension of the second mounting plate 160 is greater than or equal to 30 mm, preferably greater than or equal to 45 mm. It may moreover be textured, in particular provided with concentric or honeycomb ribs or grooves.

(115) FIGS. 8A to 8D illustrate the creation of a dividing partition C using a device 200 according to this second embodiment example.

(116) In a first step, a first primary panel P1 is attached to bottom and top brackets 91′, 92′ fastened to the floor and to the ceiling respectively.

(117) In a second step illustrated in FIG. 8B, the bracing device 200 is secured to that face of the first primary panel P1 that faces toward the inside of the partition, and therefore toward the second facing. To do that, the second mounting plate 160 is positioned with its bearing face against the face of the panel P1 and secured to that face, for example by screwing and/or by bonding.

(118) In a third step illustrated in FIG. 8C, the first mounting plate 60 of the device is engaged and adjusted for position on the body 10. Beforehand, a layer of insulation I, in particular a layer of fibrous insulation, in particular mineral wool, or a layer of animal or plant origin, may have been speared onto the shank of the device or inserted between several shanks of adjacent devices.

(119) Then a secondary panel P2 is placed to bear directly on the first mounting plate 60 (FIG. 8D) and secured to the first mounting plate 60, for example by screwing and/or bonding, in the way described hereinabove in connection with FIG. 6F.
