Description

[Technical Field]

[0001] The present invention relates generally to wall surface linings for insulation or aesthetic purposes, and more particularly to bracing accessories positioned laterally between a wall surface to be lined and a lining partition to distance the lining partition from the wall surface to be lined. [Background technology]

[0002] Lining of wall surfaces, such as walls, ceilings or roofs of buildings, is often carried out during renovation or new construction in order to obtain or improve the acoustic or thermal insulation of a building or a particular room. For this purpose, a lining partition (false wall or false ceiling) is incorporated into a lining frame, which itself is fastened to the structural elements of the wall surface to be lined at a given distance from the lining frame. A thermal and / or acoustic insulating packing (often called an insulating coating) is fitted between the wall surface to be lined and the lining partition.

[0003] The insulation packing typically includes one or more layers of fibrous insulating material, such as mineral wool, and at least one windshield or vapor-resistant membrane, often interposed between the layer of fibrous material and the lining partition, typically attached to the partition and sometimes interposed between two layers of fibrous material.

[0004] Attachment of the lining frame to the structural elements of the wall surface to be lined is achieved by uniformly spaced bracing accessories, each having a stem-shaped body extending into the wall surface to be lined and perpendicular to the lining bulkhead, one end of the body comprising a cantilever attachment means to the structural elements of the wall surface to be lined and the other end comprising a means for assembly with the lining frame. Such bracing accessories are described, for example, in WO 2006 / 061538.

[0005] During installation, the insulating packing is usually stitched to the rods of the bracing accessory, causing multiple perforations in the layer of fibrous material and, if applicable, in the membrane. These perforations are particularly detrimental to the membrane, as they impair its permanent or selective sealing function. Perforations in the membrane can also constitute a trigger for a rupture, which can propagate when tension is applied to the membrane.

[0006] To partially avoid this problem, solutions are known in which the membrane is laid inside the lining frame between the rear and the lining partition, so that the membrane is not crossed by the bracing accessories and can therefore remain intact, at least initially.

[0007] However, this solution is only partial: fixing the lining partition to the lining frame involves piercing the membrane with fastening elements (clips, screws, nails, etc.), which impairs the membrane's sealing to a lesser extent.

[0008] Positioning the membrane in front of the lining frame creates another technical problem: no gap space remains between the membrane and the lining partition. However, it is often necessary to insert various cables or pipes, including those for water, ventilation, electricity, or communication networks, behind the lining partition. This makes it difficult to position cables and wiring accessories between the membrane and the lining partition. In fact, cables can only be properly fixed through openings in the membrane. In addition, the membrane may be damaged or stretched by cables or jackets, attachments, or connection accessories.

[0009] These cables can be securely placed behind the membrane, but then it is no longer possible to access them for maintenance or to develop the installation of the wiring without removing the membrane or making an opening in it. In addition, for logistical or changing needs or technical reasons, wiring operations may intervene after lining the wall surface, which also requires the removal or opening of the membrane by workers who are generally not specialized in lining and insulating wall surfaces. Summary of the Invention [Problem to be solved by the invention]

[0010] The object of the present invention is to provide a technical solution for installing a membrane without compromising its integrity and tightness. [Means for solving the problem]

[0011] To this end, the invention provides a lining device for attaching a bracing device to a lining frame, said device comprising: a main part extending along the axial direction, one end of which is fitted with a fixing plate for the structure to be lined and the other end of which is fitted with a membrane retaining piece; It consists of the membrane holder includes a first jaw and a second jaw; The second jaw comprises two half jaws, and includes assembly means for assembling the two half jaws together to form the second jaw, and the apparatus also includes coupling means for coupling the second jaw to the first jaw.

[0012] Advantageously, this bracing device makes it possible to obtain a two-jaw assembly that is simple.

[0013] One of the advantages of the present invention is that having the second jaw assembled together in two parts and connected to the first jaw simplifies the connection of the two jaws. In fact, the bracing device according to the present invention does not require deformation of one of the jaws relative to the other in order to connect them together. Therefore, it is absolutely possible for the first jaw and / or the second jaw to be made of a material with low or no elastic deformation.

[0014] According to one example, the coupling means and the assembly means are arranged so that the locking of the two half jaws and the coupling of the first jaw with the second jaw occurs simultaneously.

[0015] According to one example, the coupling means includes at least one major complementary surface disposed on the first jaw and at least one minor complementary surface disposed on the second jaw, the major and minor complementary surfaces cooperating to assemble the jaws together.

[0016] According to one example, the first jaw has a sidewall surface on which the primary complementary surface is disposed.

[0017] According to one example, each half jaw comprises a block with a protrusion extending therefrom, the protrusion supporting a secondary complementary surface.

[0018] According to one example, the primary complementary surface includes a groove and the secondary complementary surface includes a relief that fits into the groove.

[0019] According to one example, the primary complementary surface includes a relief and the secondary complementary surface includes a groove into which the relief fits.

[0020] According to one example, the protruding portion comprises a portion extending substantially parallel to the axis of the central portion and a portion extending perpendicular to the axis of the central portion, forming a gap E between the portion extending perpendicular to the axis of the central portion and the surface of the half jaw, the space being dimensioned to allow the first jaw to be inserted therein.

[0021] According to one example, the protrusion extends to present a slope with the surface of the half jaw, and the side wall surface of the first jaw has a complementary slope to the surface of the protrusion.

[0022] According to one example, the assembly means comprises at least one screw or snap-on system.

[0023] According to one example, the jaw halves are connected together by a hinge system.

[0024] The invention further relates to a wall surface lining device, the device comprising: at least one bracing device according to the invention, a windshield, steam-resistant, or steam-check membrane attached to the bracing accessory; The membrane is characterized in that it is clamped between a first jaw and a second jaw of a bracing device.

[0025] The present invention further relates to a method for maintaining a membrane on a bracing device, the method comprising: - providing a bracing device according to one of the preceding claims fixed to a wall surface, said device comprising an axially extending main part, said main part including one end which is a first jaw of a membrane retaining piece; - providing an insulating material and fitting it between the wall surface and the first jaw; - providing a windshield, vapor-resistant, or vapor-check membrane; - placing the membrane on an upper surface of the first jaw; - providing each half jaw forming a second jaw; Including, - each half jaw is provided with assembly means which are assembled together to form said second jaw, the half jaw also comprising connecting means for connecting the second jaw with the first jaw;

[0027] According to one example, the method includes the step of decoupling the second jaw from the first jaw after attaching the bracing device to the wall surface and before retaining the membrane to the bracing device.

[0028] According to one example, the method includes the step of assembling the two half jaws to form a first jaw around the main part after attaching the bracing device to the wall surface and before holding the membrane to the bracing device. [Brief explanation of the drawings]

[Figure 19] 1 is a schematic view of a bracing accessory fitted with a profile fixing means according to the present invention; FIG. DETAILED DESCRIPTION OF THE INVENTION

[0030] In the example shown in FIG. 1, more specifically, it is important to insulate the attic of a building, and for this purpose the external walls 1 and roof 2 of the building are lined.

[0031] The roof 2 here conventionally comprises a framework forming panels 3 supporting rafters 4 on which roof elements 5 rest.

[0032] The lining device according to the invention is arranged against the roof frame and on the exterior walls, and consists of a lining frame made up of horizontal battens 6 for lining the roof and vertical battens 7 for lining the walls 1. These battens are generally called furring strips in the case of walls and rafters and / or beams in the case of roofs.

[0033] The lining battens 6 and 7 are attached to the structural elements of the roof 2 and of the wall 1 which is lined by a number of bracing accessories 10, respectively.

[0034] Each bracing accessory 10, visible in Figures 2a and 2b, has a central portion 11 in the form of a rod 12 extending along an axis X1 and fitted with its attachment means 14 to a wall surface, which in a first implementation mode can be a roof 2 or a wall 1, while its other end, pointing upward, is provided with a connecting piece with its assembly means 30 to ensure the attachment of the accessory to the lamellas 6, 7. When placed, the rod 12 is adjusted to extend in a direction substantially perpendicular to the wall 1. In the case of a roof, the rod 12 is arranged to extend in a direction substantially perpendicular to the ground in order to create a false horizontal ceiling relative to the ground. Panels of insulating material are arranged between the roof 2 or wall 1 and the battens 6, 7 used to support the wall surface lining.

[0035] Bracing accessories 10 used for lining the roof are attached to the rafters 4. For this purpose, each has as attachment means 14 a vertical plate or base of a mounting fixture 141 that is screwed to the side of the relevant chevron 4. For this purpose, bracing accessories 10 attached to a wall 1 each have as attachment means 14 a horizontal mounting plate 142 that is screwed to the wall 1.

[0036] The plates 141, 142 may be part of the rod 12 or may be parts that are fitted to the rod 12 by various means.

[0037] According to an advantageous feature shown in FIG. 3, the rod 12 is designed to allow its length to be adjusted. The rod 12 has a first portion 121 and a second portion 123. The rod's attachment means 14 are arranged on the first portion 121, while the assembly means 30 with the laths 6, 7 that ensure its support are arranged on the second portion 123, and vice versa. Adjustment means 125 are provided to allow the position of the second portion 123 relative to the first portion 121 and thus to adjust the length of the rod 12. Such adjustment means 125, for example, allow the first portion 121 and the second portion 123 to slide relative to each other. This sliding movement can be performed, for example, through a system of rails or a system using a tube in which a sliding rod slides. However, other systems can also be used, such as a system in which both portions are snapped together.

[0038] Thus, each bracing accessory, when fitted with all its fixing plates, typically has an overall length (corresponding to the distance between its end points along its longitudinal direction) of 200 to 350 millimeters.

[0039] At one end, opposite the fixing means 14, the rod 12 comprises means for mounting the membrane 13. These means for mounting 13 comprise a first jaw 15 and a second jaw 17. As can be seen in Figure 4, the first jaw 15 is fixed to the central part 11 or is made of a material that accompanies said central part 11.

[0040] The first jaw 15 cooperates with the second jaw 17 through coupling means 19. These coupling means 19 are carried by the first jaw 15 and the second jaw 17.

[0041] According to the invention, the coupling means 19 are arranged to allow axial tightening of the first jaw 15 and the second jaw 17 while, after coupling, clamping the membrane M therebetween. More precisely, this clamping of the membrane M by the first jaw 15 and the second jaw 17 helps to avoid piercing or perforating the membrane and thus avoiding weakening it or causing local loss of performance.

[0042] According to the invention, the second jaw 17 consists of two half jaws 170. These half jaws 170 are arranged to cooperate with one another and assemble to form the second jaw 17.

[0043] As shown in Figure 5, the half jaws 170 are attached by assemblies 18. These assembly means 18 can take different forms to allow the half jaws 170 to be assembled.

[0044] According to a first example, the two half jaws 170 are assembled together by screwing. The half jaws are arranged so that the screws allow the two half jaws to be assembled.

[0045] According to a second example shown in FIG. 6, the two jaw halves 170 are assembled together by a snap-on system.

[0046] The snap-on system consists of at least one deformable blade 181 with a notch and arranged in one half jaw, while the other half jaw comprises at least one housing 182. The deformable blade can be deformed to move into or out of the housing, in the latter case with a slot that fits into the notch.

[0047] 7 and 8, a snap-on system mates each half jaw with a blade 183 and housing 184, with the housing 184 arranged to face the blade 183 of the other jaw. The blade 183 optionally includes a relief or notch 183' that allows for better assembly of the half jaws 170.

[0048] 8 and 9, the two jaw halves 170 are joined together by a hinge system 185. This hinge system 185 can be a band or strap hinge system of deformable material or can use a blade 183 and housing 184. This hinge allows the jaw halves 170 to rotate along an axis parallel or perpendicular to the central axis of the central portion.

[0049] In another example, the two half jaws 170 are assembled together by inserting at least one blade extending from one of the half jaws into a housing disposed in the other half jaw.

[0050] Advantageously, according to the invention, the two half jaws 170 are designed to cooperate with the first jaw 15 to clamp the membrane when it is locked into the trap. For this purpose, coupling means 19 are used.

[0051] These joining means 19 work on the principle that the main complementary surface 191 and the secondary complementary surface 192 cooperate to form an assembled whole, which therefore makes it possible to clamp the membrane without damaging it.

[0052] To this end, Figure 10 shows a first jaw 15 in the form of a piece 150 of any shape having a side wall surface 151 that is a wall surface substantially parallel to the axis of the central portion 11. The portion forming the first jaw 15 comprises an upper surface 152 and a lower surface 153. This side wall surface 151 includes at least one region that forms a first major complementary surface 191.

[0053] As can be seen in FIG. 10 , each half jaw 170 forming the second jaw 17 takes the form of a block 171 with a protrusion 172. The block 171 forming the half jaw 170 may have a contoured or quarter-hemispherical shape, or any shape suitable for use. The protrusion 172 defines a sidewall surface 173 that extends substantially parallel to the axis of the central portion 11. The sidewall 173 of the protrusion of each half jaw 170 is configured to define a minor complementary surface 192. Each half jaw 170 has a top surface and a bottom surface, the bottom surface being the surface that faces the first jaw 15.

[0054] Ideally, the side wall surface 173 of the protrusion 172 of each half jaw 170 is configured to form one minor complementary surface 192 per half jaw 170. In this case, the side wall surface 151 of the first jaw 15 comprises at least one region forming the major complementary surface 191, which region extends in such a way as to cooperate with the minor complementary surface 192 of each half jaw 170. Alternatively, the side wall surface 151 of the first jaw 15 includes a plurality of regions forming the major complementary surface 191, ideally as many as the number of minor complementary surfaces 192.

[0055] According to a first example shown in Figures 11a and 11b, the first jaw 15 takes the form of a plate 150 of constant thickness and regular shape, which may be circular, square, rectangular or any other regular shape, and which has peripheral side wall surfaces 151 which are substantially parallel to the axis of the central part 11.

[0056] In this first example, the protrusion 172 of the half jaw 170, configured to form the secondary complementary surface 192, includes a hook 174. The hook 174 is L-shaped and includes a portion 174a extending substantially parallel to the axis of the central portion and a portion 174b extending perpendicular to the axis of the central portion. The hook 174 is dimensioned to allow the first jaw 15 to be inserted into a gap E between the portion 174b extending perpendicular to the axis of the central portion and the surface 171a of the half jaw 170. In this case, the portion 174b extending perpendicular to the axis of the central portion contacts the underside of the first jaw 15.

[0057] In a variation of this first example, the plate 150 consists of two sections that protrude from the end of the rod 12. These two sections are made so that they can be inserted into the space E. Preferably, the two sections extend a length of no more than 5 mm, preferably no more than 3 mm.

[0058] Thus, when the two half jaws are placed together, the plate 150 forming the first jaw 15 fits into the space E of each half jaw 170 .

[0059] In a second example, which can be seen in Figures 12a and 12b, the first jaw 15 takes the form of a block 150' with a bottom surface 153', a top surface 152', and a side wall surface 151'. This block can have steps on two opposite sides to have a stepped profile. In such a design, the side wall surface is in two parts: an upper part 151a' and a lower part 151b'. This first jaw 15 has at least one groove 193 extending in the plane of the first jaw 15 and perpendicular to the axis of the central part. This groove 193 forms the main complementary surface 191. This groove 193 is disposed in the side wall surface 151' of the lower or upper part. This groove 193 can also be disposed at the junction between the upper part 151a and the bottom part 151b. Ideally, the first jaw 15 includes two grooves 193, one in each half jaw 170', which are arranged diametrically opposed.

[0060] This groove 193 is capable of cooperating with a secondary complementary surface 192 on the jaw half 170 .

[0061] In this second example, the protrusion 172 of each half jaw 170' takes the form of a portion extending substantially parallel to the axis of the central portion, said portion 172 comprising a relief 194 forming a secondary complementary surface 192 in the form of a line whose shape and dimensions allow said relief 194 to fit into a groove 193 of the first jaw.

[0062] Alternatively, the major complementary surface 191 of the first jaw 15 may have a relief 194 and the minor complementary surface 192 of each half jaw 170 may have a groove 193 .

[0063] Thus, when the jaw half 170 is placed, the relief 194 fits into the groove 193 to allow the second jaw 17 and the first jaw 15 to be joined together.

[0064] In a third example, shown in Figures 13a, 13b and 13c, the first jaw 15 takes the form of a plate 150" of constant thickness and regular shape. This shape can be circular, square, rectangular or any other regular shape. This plate has a circumferential side wall surface 151", a top surface 152", and a bottom surface 153" that is attached to the central portion 11. This plate 150" can have steps on two opposite side surfaces to have a stepped profile. In such a design, the side wall surface is in two parts: an upper part and a lower part.

[0065] This wall surface 151'' is arranged to have at least one inclined portion 151c'' forming a major complementary surface 191''. This inclined portion 151c'' may extend over the entire side wall surface 151''' of the upper or lower portion. This inclined portion 151c'' may also extend to allow the minor complementary surface 192'' of each half jaw 170 to cooperate with it. Alternatively, the first jaw 15 consists of two inclined portions 151c''. The inclination of the inclined portion(s) 151c'' is such that the top surface is greater than the bottom surface. The first jaw 15 has a contour that is substantially trapezoidal in shape.

[0066] In this third example, the protrusions 172 on each half jaw 170 can have different shapes.

[0067] The first shape consists of a blade 1720 or plate extending at an angle from the jaw half. The second shape of the protrusion consists of a solid or hollow profile 1721 in a shape with an inclined surface, such as an oblong triangle, oblong trapezoid, or other shape. The inclined surface of the protrusion 172 thus forms a housing with the surface of the jaw half 170 from which it extends.

[0068] The beveled surface of the protrusion 172 is arranged to cooperate with the beveled surface of the first jaw so that the protrusion fits perfectly with the beveled surface of the first jaw 15. The beveled surface of the first jaw 15 thus penetrates into a housing formed by the beveled surface of the protrusion 172 and the surface of the jaw half 170 from which it extends.

[0069] In the case of a first jaw 15 having a step and stepped profile, the upper and / or lower portions can have beveled surfaces. The half jaws 170 are arranged to have one or two beveled surfaces to cooperate with the beveled surface(s) of the first jaw 15.

[0070] This jaw 15 is a piece that is integrated with the rod 12 or with an insert that attaches to the rod 12. If it is an integrated part, the plate 150, 150', 150'' includes through holes or mismatched holes directly in the plate or in extensions extending from the plate. This allows the first jaw 15 to be screwed or snapped into place or pressed onto the rod 12. The installation process consists of attaching the central part to the wall surface P to be lined via fixing means 14, which can be seen in Figure 14a. This fastener uses screws or nails or adhesive to fix the central part 11 perpendicular to the wall surface to be lined.

[0071] Then, as can be seen in Figure 14b, a step of adjusting the length of the central portion 11 is carried out, if said central portion is adjustable, which consists in operating the adjustment means 125 to make it possible to adjust the length of the central portion, which comprises at the rear a first part and a second part that slide relative to each other.

[0072] After this adjustment step, a step is performed consisting of fitting an insulating material with the bracing accessory, the insulating material being placed between the wall surface to be insulated and the first jaw, the fitting being dependent on the configuration of the bracing device.

[0073] The first way to fit the insulator is to insert it onto the rod 12. This method of fitting the insulator is possible if the first jaw is an insert on the rod 12. This fitting occurs before the first jaw 15 is installed.

[0074] A second method of fitting the insulating material is to position the insulating material so that it rests against the lower surface 153, 153', 153''.

[0075] This lower surface 153, 153', 153'' is, in a first option, provided with teeth that extend perpendicular to the lower surface 153, 153', 153''. These teeth penetrate the blocking material and make it possible to retain the blocking material.

[0076] According to a second option, the bracing device comprises an additional plate attached to the rod 12. This plate provides a surface on which the insulating material rests.

[0077] This second approach is possible for the first jaw 15 to be part of or connected to the rod 12 .

[0078] In the case of a first jaw 15 that is not part of the rod, an optional step is performed consisting of attaching the first jaw to the main part (as can be seen in FIG. 14c). In fact, the kit of bracing devices comprises a central part, a first jaw 15 and a second jaw 17, and said first jaw 15 is not mounted with the central part. It is therefore necessary to have a step of fixing the first jaw 15 to the main part.

[0079] Another optional step (not shown) for both methods of installing the insulation is to disassemble the second jaw 17 from the first jaw 15. In practice, the bracing device kit comprises a central part, a first jaw 15 and a second jaw 17, which can be pre-fixed to the first jaw 15.

[0080] The operating procedure for coupling the two jaws 15, 17 and the coupling means 19 is as follows.

[0081] 14d, 14e and 14f, consists of providing a membrane M and placing it in the first jaw 15. The membrane M is advantageously an airtight and / or water vapor management membrane, preferably a membrane M that provides both functions. Advantageously, the water vapor management membrane is a vapor-resistant or humidity-regulating membrane, i.e., its water vapor permeability varies with the relative humidity of the room. The membrane M consists of one sheet or several sheets assembled together. This placement of the membrane M in the first jaw 15 is such that the membrane M is placed on the surface of the first jaw 15 opposite to the surface to which the first jaw 15 is attached to the central part.

[0082] In a second step, which can be seen in Figures 14g, 14h, and 14i, the two half jaws 170 are assembled together to form the second jaw 17, which is coupled to the first jaw 15.

[0083] According to a first method, the two half jaws 170 are assembled together before being coupled and locked to the first jaw 15. This first method is very practical in the case of half jaws 170 equipped with a hinge system 185. Indeed, in this first method, the half jaws 170 are attached to each other before being coupled to the first jaw 15. This coupling is performed simultaneously with the locking of the two half jaws 170 together.

[0084] According to the second method, this second step is performed such that the assembly of the half jaws 170 to the second jaw 17, their locking, and the coupling of the second jaw with the first jaw occur simultaneously. It will thus be appreciated that the operator performs only one action to assemble the two half jaws 170 together, lock them, and couple these half jaws 170 to the first jaw 15.

[0085] In fact, this second step consists of supporting together the two half jaws 170. The half jaws 170 are then manipulated so that the protrusions of the half jaws with the secondary complementary surfaces 192 can cooperate with the primary complementary surfaces 191 to form the second jaw 17.

[0086] In the first example, the second step consists of assembling the two half jaws 170 while inserting the first jaw 15 into the space E of each half jaw 170 between the inclined portion 174b extending perpendicular to the axis of the central portion and the surface of the half jaw 170.

[0087] In the second example, the second step consists of assembling the two half jaws 170 while inserting the relief 194 of the protrusion of each half jaw 170 into a groove 193 arranged in the side wall surface of the first jaw 15.

[0088] In the third example, the second step consists of assembling the two half jaws 170 while inserting the first jaw 15 into the housing formed by the inclined surfaces and the projections 1720, 1721 mated with the half jaw 170 from which this projection extends.

[0089] In this case, the membrane previously placed in the first jaw 15 is inserted between the major complementary surface 191 of the first jaw and the minor complementary surface 192 of the second jaw. Shimming this membrane between the first jaw 15 and the second jaw 17 provides fixation and retention of the membrane.

[0090] Advantageously, this configuration of jaws 15, 17 makes it possible to hold the membrane without violating its integrity: in fact, here the membrane is captured between the two jaws so that the complementary surfaces do not perforate the membrane.

[0091] In a first variant, the first jaw 15 and the second jaw 17 are such that they have a circular geometric shape. This circular geometric shape applies mainly to the first jaw. In particular, this circular geometric shape applies to the shape of the side wall surface 151 of the first jaw 15, on which the half jaws 170 join in area(s) that form complementary surfaces.

[0092] In the first and third examples, the substantially circular shape of the side wall surfaces by itself allows for tilting freedom for the assembly of the two jaws. Indeed, as can be seen in Figure 15, the circular shape allows the operator to install the two half jaws 170 without any tilting position constraints. Figure 16 shows the first jaw 15 having a substantially circular or octagonal shape.

[0093] In the case of a first jaw having a claw, the upper and / or lower portion is circular if the upper portion is used to assemble the two jaws.

[0094] In a second example, if the groove 193 into which the relief 194 of the secondary complementary surface 192 fits extends around the periphery of the side wall surface 151', then this side wall surface is circular.

[0095] When the first jaw is disengaged, at least the upper portion is circular if the portion supports the groove, and if the groove is disposed in the lower portion, both the upper and lower portions are circular.

[0096] In a second variant, which can be seen in FIG. 17, the half jaws 170 are arranged so that the protrusion 172 of each half jaw 170 matches the shape of the side wall surface that forms the primary complementary surface. Indeed, having the protrusion 172 extending linearly along the width of the half jaw 170 helps to retain the membrane M. However, if the side wall surface 151 that forms the primary complementary surface is circular, the protrusion does not allow for optimal retention. Cleverly, according to the second variant, the protrusion 172 is arranged so that the secondary complementary surface and the primary complementary surface extend in a manner that perfectly mates. Advantageously, this variant makes it possible to have the entire secondary complementary surface useful for retaining the membrane and for connecting the second jaw to the first jaw.

[0097] In a third variant, not shown, the first jaw 15 comprises two half jaws. This variant applies to jaws attached to the central part.

[0098] These two half jaws of the first jaw 15 cooperate with one another to form said first jaw 15. The fixing is effected via assembly means, which can take different forms in order to make it possible to assemble the half jaws of the first jaw 15.

[0099] According to a first example, the two half jaws are assembled together by screwing them together. The half jaws are arranged so that a screw allows the two half jaws to be assembled.

[0100] According to a second example, the two half jaws are assembled together by snapping. To do this, one of the half jaws has at least one deformable blade with a notch, and the other jaw has a housing. The deformable blade can be deformed to enter or exit the housing, and in the latter case, has a slot that fits into the notch.

[0101] In an alternative to the two examples, the two jaw halves are joined together by a hinge, which may be a strip of deformable material, or a strap hinge system.

[0102] In another variant, which can be seen in Figures 18 and 19, the two half jaws 170 forming the second jaw 17 are arranged to allow the frame to be fixed. For this purpose, frame fixing means 30 are provided. These fixing means 30 are arranged on the upper surface of at least one half jaw 170. These means 30 consist of grooves 31, which can be, for example, circumferential or two parallel sections arranged in the second jaw to allow the attachment of a U-shaped profile P. In practice, such a profile consists of a metal, plastic, or polymer sheet folded to have two parallel arms that allow a U- or C-shape to be obtained depending on the orientation of the profile. The ends of each arm of the profile exhibit an excess thickness. This offset can be inserted into the groove to allow the profile to be fixed.

[0103] Alternatively, the means for fixing the frame may include two parallel arms 33 extending from the second jaw 17 in a direction parallel to the axis of the central portion and having a gap so that they can fit into the space between the two arms of the U-shaped or C-shaped profile.

[0104] Naturally, the invention is not limited to the examples illustrated but is capable of various variations and modifications that will occur to those skilled in the art.
