Description

[0001] The present invention relates to a roller shutter tube support, a mounting subassembly comprising such a support and a protective installation comprising such a subassembly or such support.

[0002] In buildings whose exterior walls have openings for joinery such as a door or window, these openings are generally equipped with a protective system, for example against intrusions, with a screen such as a roller shutter, or a solar protection system, with for example a screen such as a solar canvas, a roller shutter, a slatted blind or an adjustable sunshade, also called "BSO", or even an insect protection system, with a mosquito net.

[0003] Generally, the protective screen is attached to a tube, which is housed in a recess created at the top of an opening. For example, this recess may be defined by the roller shutter housing or directly within the wall, such as in a lintel. The tube has two end bearings, each supported by a flange, allowing the tube to pivot relative to the flanges around a winding axis.

[0004] Each end plate is typically supported by a bracket, which is attached to other components of the protective system. Specifically, each bracket is usually fitted into its respective guide rail for the protective screen. A guide flange for the curtain is provided at each guide rail to guide the curtain within the corresponding rail. Each flange is typically clipped onto the end plate. Together with its corresponding flange, each end plate forms a support for the roller shutter.

[0005] FR-3 115 809-A1 describes, for example, a tube support comprising a flange, a lug, and a tulip-shaped fitting. The flange includes a spring tab cut into its body and pins attached to the flange body, while the lug includes notches that complement the pins. The flange and lug are locked together by the spring tab. During assembly, the force required to push back the spring tab is generally significant. Furthermore, to secure the assembly, an additional step is required: the installer plastically deforms the tab using a tool, which requires considerable effort. Disassembly also requires plastically deforming the tab in the opposite direction, which is impractical and may render the part unsuitable for subsequent reuse.

[0006] It is these problems that the invention aims to remedy in particular, by proposing a tube support that is easier to assemble and disassemble, in particular without requiring significant effort.

[0007] To this end, the invention relates to a roller shutter tube support, this support being configured to support a winding tube of a roller shutter installation, the support comprising: a flange, which has a front face extending orthogonally to a winding axis, and a rear face opposite the front face, the flange comprising: a recess configured to receive an end bearing of the winding tube, and an attachment portion; a lug, which includes: a fixing tenon, which has a flattened and elongated shape, the tenon extending in a tenon plane along a fixing axis and being configured to be fixed to the attachment portion of the flange; and a fitting, which has an elongated and flattened shape extending in a fitting plane along a fitting axis, the fitting being configured to be fixed to a wall, the fitting having a free end and a captive end, which is opposite the free end and which is connected to the tenon; a tulip, which provides a channel for fitting the fitting and which includes a first elastic clip configured to cooperate, in particular by complementary form,with a first opening made in the fitting, so as to fix the tulip to the fitting when the fitting is fitted into the conduit, the tulip and the tab fixed to the tulip together forming a first sub-assembly in a fitted configuration, in which: The attachment portion includes side walls, the side walls being substantially parallel to an insertion direction of the attachment portion and delimiting between them a passage for the tenon; the tenon is configured to be inserted into the passage by an insertion movement, the insertion movement being a translational movement parallel to the insertion direction, the fixing axis being aligned with the insertion direction; the flange includes a third wall, which is arranged so that when the fitting is fitted into the conduit, forming the first sub-assembly, and the tenon is inserted into the passage, the movements of the first sub-assembly relative to the flange are limited to a translation parallel to the insertion direction; the tulip includes a second elastic clip, which is configured to cooperate with a second orifice provided on the flange when the first sub-assembly is in the fitted configuration.in order to prevent translational movements of the first subassembly relative to the flange parallel to the insertion direction, the support being in an assembled configuration when the second elastic clip cooperates with the second orifice, the tulip includes an extension, which extends from one end of the second clip and terminates in a gripping portion, the gripping portion being configured to allow the user to elastically deform the second clip so as to disengage the second elastic clip from the second orifice, allowing the first subassembly to move away from the flange parallel to the insertion direction.

[0008] Thanks to this invention, assembling the support is particularly easy and quick, requiring no special effort, as the support components are held in place by the first and second clips on the tulip-shaped bracket. The only effort required is to deform the elastic clips, and this effort is minimal and hardly noticeable. Disassembly is simple: just press on the gripping portion to disengage the second clip, which can also be done by hand without tools.

[0009] According to advantageous but not mandatory aspects of the invention, such a support may incorporate one or more of the following features taken individually or in any technically permissible combination: The support also includes a rider, which comprises a body providing a cavity for receiving the gripping portion. The cavity opens through an opening for the passage of the gripping portion. The rider is in an engaged position when the gripping portion is received in the cavity, bearing against stops formed in the bottom of the cavity. When the support is in its assembled configuration and the rider is in the engaged position, the support is in a secure configuration. The rider includes support tabs, which are configured to cooperate with the flange so that, when the support is in the secure configuration, the rider retains the second elastic clip in the second opening. The support tabs include a main tab and secondary tabs, which are located on either side of the flange when the support is in the secure configuration, so as to clamp the flange.The body of the rider includes at least one opening, which is formed in the body through which the cavity opens to the outside of the body on the front face when the support is in the secure configuration. This opening is configured to allow the user to see the gripping portion received in the cavity when the rider is in the engaged position. The rider includes lugs, which are formed on the body and extend inward into the cavity. These lugs are configured to cooperate with the gripping portion, notably through complementary shapes, so as to maintain the rider in the engaged position.

[0010] The invention also relates to a sub-assembly of the assembly, comprising: two tube supports, at least one of the supports being as defined previously, and a winding tube with two end bearings, each of the bearings being supported by a respective flange, the tube being mounted pivotally relative to the flanges.

[0011] The invention also relates to a protective installation, in particular a roller shutter, comprising: a mounting subassembly as defined above, and a protective screen, in particular a roller shutter screen, which is attached to the winding tube and configured to wind around or unwind from the tube, depending on the rotational movements of the tube, in which: the supports are attached to a wall and are located above an opening made in that wall.

[0012] The invention will be better understood, and other advantages thereof will become more apparent in the light of the following description of several embodiments of a roller shutter flange, a roller shutter installation, and an assembly method, conforming to its principle, given solely by way of example and with reference to the accompanying drawings, in which: [ Fig 1 ] there figure 1 is a perspective view of a roller shutter installation according to a first embodiment of the invention, the roller shutter installation comprising a mounting sub-assembly, which includes a winding tube supported by two brackets; [ Fig 2 ] there figure 2 represents, on two inserts a) and b), a detail IIa) of the assembly sub-assembly of the figure 1 observed from two different viewpoints, with some parts hidden; Fig 3 ] there figure 3 is a partially exploded perspective view of the subset of the figure 2 , some parts being hidden; Fig 4 ] there figure 4 represents, on three inserts a), b) and c), a support for the mounting sub-assembly of the figure 2 , the support being represented, respectively, in exploded perspective from two different viewpoints, and in a first intermediate configuration; Fig 5 ] there figure 5 represents in perspective, on two inserts a) and b), the support of the figure 3 , the support being represented respectively in the first intermediate configuration, with some parts hidden, and in an assembled configuration; Fig 6 ] there figure 6 represents respectively, on two inserts a) and b), two sections, along two parallel planes Vla and VIb to the figure 5 , of the assembly sub-assembly of the figure 3 in assembled configuration; [ Fig 7 ] there figure 7 represents, on three inserts a), b) and c), a tube support belonging to a roller shutter installation according to a second embodiment of the invention, and a perspective, from two different viewpoints, of a part of this support; [ Fig 8 ] there figure 8 represents, on three inserts a), b) and c), the tube support of the figure 7 , observed from two different viewpoints, and a cross-section of a detail of the tube support, and [ Fig 9 ] there figure 9 represents respectively, on two inserts a) and b), the tube support of the figure 7 in two different configurations.

[0013] A protection installation 10 is schematically represented on the figure 1 Installation 10 is an intrusion protection system, which includes a roller shutter. Therefore, this protection system is a roller shutter installation.

[0014] The installation 10 is fixed to a wall 12, assumed to be flat and vertical, in which an opening 14 is provided, passing through the wall 12. The opening 14 is covered by a protective screen 24, which belongs to the protective installation 10. The protective screen 24 is here a roller shutter curtain. As non-limiting alternatives, the screen 24 is a solar shade, or even a mosquito net, etc.

[0015] Installation 10 includes a box 18, which is schematically represented using dashed lines. The box 18 is fixed to the wall 12, above the opening 14. The box 18 has an elongated, generally parallelepiped shape and extends along its length along a box axis A18. The box axis A18 is assumed to be horizontal. The description is based on the orientation of the components of installation 10 as shown in the drawings, although this may differ in reality. Installation 10 has a generally symmetrical structure with respect to a transverse plane T18 of the installation, the transverse plane T18 being orthogonal to the box axis A18.

[0016] The box 18 provides a receiving volume V18 for other parts of the installation 10, as described below. By way of non-limiting example, the box 18 is made from an assembly of boards.

[0017] According to a first alternative (not shown), the receiving volume V18 is partially delimited by wall 12, for example, within wall 12, specifically within a lintel that defines the upper part of opening 14. This configuration corresponds to a so-called "half-lintel" mounting. According to a second alternative (not shown), the receiving volume V18 is essentially contained within the lintel, according to a so-called "lintel" mounting configuration. These alternatives are not exhaustive.

[0018] The installation 10 comprises a tube 20, which in this case is a winding tube for the screen 24, and two brackets 30, which are fixed to the wall 12 and configured to support the tube 20. The two brackets 30 are arranged symmetrically with respect to the transverse plane T18 of the installation 10, the two brackets 30 having an overall symmetrical structure with respect to each other. What is true for one of the two brackets 30 is transposable to the other bracket 30.

[0019] The tube 20 comprises two opposite ends, each of which is equipped with an end bearing 22. Each of the end bearings 22 is supported by a respective support 30, so that the tube 20 is pivotally mounted relative to the supports 30, around the trunk axis A18.

[0020] Each of the supports 30 respectively supports one of the end bearings 22 of the winding tube 20, so that the tube 20 is mounted pivotally relative to the supports 30 around the winding axis A18. The two supports 30 assembled to the tube 20 together form a mounting sub-assembly 40 of the installation 10.

[0021] An upper end 25A of the screen 24 is attached to the tube 20, here by means of two locks 26 belonging to the installation 10. It is understood that according to the direction of rotation of the tube 20 around the trunk axis A18, the screen 24 winds or unwinds around the tube 20, a lower end 25B of the screen 24 rising or falling in front of the opening 14. By extension, the trunk axis A18 is also a winding axis of the tube 20.

[0022] The rotation of tube 20 is controlled by a user via a drive device. The drive device is not shown. Depending on the configuration, the drive device is either manual, for example with a crank and gear system or a belt drive, or motorized, with an electric motor. In the case of a motorized drive device, part of the motor is usually housed within tube 20, while a pivoting head of the motor protrudes from the tube and forms one of the tube's bearings.

[0023] Each support 30 is secured to the wall 12, that is, fixed to the wall 12, either directly or via another element of the installation 10. In the illustrated example, each support 30 is fixed to a respective track 32, the track 32 being fixed to the wall 12. The installation 10 thus comprises two tracks 32, which are located opposite each other, symmetrically with respect to the transverse plane T18. Each track 32 extends vertically along one side of the opening 14, the two tracks 32 serving to guide the screen 24, particularly during the raising or lowering movements of the lower end 25B of the screen 24.

[0024] In the illustrated example, each bearing 22 comprises a star-shaped part, which is received in a complementary recess 312 formed in the support 30. Each bearing 22 thus received in the complementary recess is prevented from rotating, relative to the support 30, around the winding axis A18. The shape of the bearing 22 is not limiting as long as the bearing 22 is prevented from rotating when it is in the recess 312.

[0025] In the illustrated example, the star-shaped recess 312 receives the bearing 22 of the winding tube 20. Naturally, the flange 300 is configured to receive any type of part with a shape compatible with the recess 312, including an adapter piece, as described in published application FR3118479 (A1).

[0026] Support 30 shown on the right of the figure 1 is shown on a larger scale, with the associated slide 32 and the associated end bearing 22, on the figure 2 The rest of the description is made with reference to this support 30.

[0027] Each support 30 includes a leg 100, a tulip 200 and a flange 300.

[0028] The lug 100 is here formed from a metal plate, preferably steel. The lug 100 is, for example, manufactured by cutting. In reference to the figure 4 The leg 100 includes a fixing tenon 102, by which the leg 100 is configured to be assembled to the flange 300, and a fitting 104, by which the leg 100 is configured to be fixed to the wall 12. The fitting 104 having a free end 105, which here has a tapered shape, and a captive end, which is opposite the free end 105 and which is connected to the tenon 102. In the illustrated example, the legs 100 are fixed to the wall 12 by means of the slides 32, the fitting 104 of each leg 100 being fixed to a respective slide 32, which is fixed to the wall 12.

[0029] The tenon 102 has a flattened and elongated shape, extending in a tenon plane P102 along a fixing axis A102. The fitting 104 has an elongated and flattened shape extending in a fitting plane P104 along a fitting axis A104.

[0030] With reference to figures 2 And 3 The tulip 200 comprises an outer wall 202A and an inner wall 202B, which are arranged opposite each other and connected by a base 202C. The outer wall 202A and the inner wall 202B diverge from each other, hence the name "tulip". The outer wall 202A, the inner wall 202B, and the base 202C are configured to guide an edge of the protective screen 24 along one front side of the base 202C, so as to limit friction between the screen 24 and the corresponding slide 32.

[0031] The tulip 200 provides a channel 204 for inserting the fitting 104, in particular for inserting the free end 104 of the fitting 104. The tulip 200 includes a first elastic clip 206 configured to cooperate, notably by complementary shape, with a first orifice 106 provided in the fitting 104, so as to fix the tulip 200 to the fitting 104 when the fitting 104 is inserted into the channel 204, in a inserted position of the tab 100 relative to the tulip 200. When the fitting 104 is in the inserted position in the channel 204, the tulip 200 and the tab 100 together form a first subassembly 410, which is then in a so-called "inserted" configuration, as illustrated in the figure 4 c) .

[0032] The flange 300 has a front face 302A, which is generally flat and extends orthogonally to the winding axis A18, and a rear face 302B opposite the front face 302A. The flange 300 includes a mounting portion 310, which has a recess 312 configured to receive one of the end bearings 22 of the winding tube 20. The front face 302A faces the tube 20 when the tube 20 is assembled to the support 30.

[0033] In the illustrated example, the flange 300 includes a peripheral portion 350, which is configured to be secured to the rest of the roller shutter installation 10 and in which a slot 352 is provided for receiving the fixing portion 310. The slot 352, which here has an oblong hole shape, comprises two opposing straight edges 352A and 352B that are parallel to an adjustment axis A352. The shape of the slot 352 is not limiting.

[0034] The fixing portion 310 is configured to be assembled to the peripheral portion 350 by being received in the slot 352 in an assembled configuration of the flange 300. The fixing portion 310 is made of synthetic polymer material and is preferably produced by hot injection molding. The peripheral portion 350 is made of a metal plate, preferably steel, and is produced in particular by stamping and / or deep drawing.

[0035] The fixing portion 310 is advantageously adjustable in position relative to the peripheral portion 350 along the adjustment axis A352. It is thus possible to adjust the position of the tube 20 relative to the supports 30, during the assembly of the installation 10, in particular according to the size of the screen 24. Once the installer has placed the fixing portion 310 in the appropriate position, the installer locks the fixing portion in position 310 by means of a locking member 370, here a ring fitted with elastic clips.

[0036] In the illustrated example, the fixing portion 310 includes a wall 314, which defines the footprint 312. The wall 314, and by extension the footprint 312, have a cylindrical shape centered on the winding axis A18, the wall 314 delimiting an internal volume V312 which is configured to receive one of the end bearings 22 of the winding tube 20 according to an insertion movement F312 of the bearing 22 into the footprint 312. The wall 314 has an internal side, oriented towards the side of the internal volume V312, and an external side, oriented opposite to the internal side.

[0037] The F312 insertion movement, which is represented by an arrow at the figure 3 , is a translational movement parallel to the winding axis A18. The bearing 22 has a shape complementary to the footprint 312, so that the bearing 22 is blocked in rotation relative to the fixing portion 310, and by extension relative to the flange 300, around the winding axis A18.

[0038] Advantageously, the flange 30 incorporates a locking device, which facilitates the assembly of the bearing 22 to the flange 30. Thus, the mounting portion 310 also includes an opening 386, which is formed through the wall and leads into the internal volume. In the illustrated example, the mounting portion 310 includes three openings 316, which are evenly distributed around the winding axis A18.

[0039] The flange 300 also includes a locking piece 380, which here generally has the shape of a ring 382 with a control tab 384. The control tab 384 is connected to the ring 382 and is configured to be actuated by an installer, so as to control the movements of the locking piece 380 and to lock the bearing 22. This aspect is not detailed further in the context of this description.

[0040] The flange 300 advantageously includes markings 304, for example pictograms and / or alphanumeric characters, which are arranged so as to indicate to the user, according to an angular position of the control tab 384 around the winding axis A18, whether the locking piece 380 is in either the locked position or the withdrawn position.

[0041] In the illustrated example, the inscriptions 304 are engravings, which are located on the peripheral portion 350 and which here represent a closed padlock and an open padlock.

[0042] The mounting portion 310 and the peripheral portion 350 each comprise a front face, which together form the front face 302A of the flange 300 when the mounting portion 310 is assembled to the peripheral portion 350, as shown in figure 2 , where the 300 flange is in a so-called "engaged" configuration.

[0043] The flange 300 includes stop means, which are provided in at least one of the elements selected from the peripheral portion 350 and the fixing portion 310. The stop means are configured to limit the relative movements of the fixing portion 310 with respect to the peripheral portion 350 to translational movements along the mounting axis A352 when the stop means are in an engaged configuration, the flange then being in the engaged configuration.

[0044] In the illustrated example, the stop means include a peripheral rim 354, which is formed on the peripheral portion 350 at the edge of the opening 352. The peripheral rim 354 includes two straight segments 354A and 354B, each of which is set back from the front face of the peripheral portion 350 and which form the straight edges 352A and 352B of the opening 352. The peripheral rim 354 is discontinuous here, so as not to generate movements of the tongue 384.

[0045] The stop means also include two complementary segments 332A and 332B, which are formed on the mounting portion 310. Each complementary segment 332A or 332B is configured to cooperate, particularly through complementary shapes, so as to slide against a respective straight segment 354A or 354B when the flange 30 is in the engaged configuration. Advantageously, when the flange 300 is in the engaged configuration, the front face of the mounting portion 310 is coplanar with the front face of the peripheral portion 350. This avoids the risk of interference with the screen 24 during the use of the installation 10. The arrangement and shape of the stop means are not limiting.

[0046] The flange 300 also includes adjustment means. The stop means and the adjustment means are configured so that, when the fixing portion 310 is assembled to the peripheral portion 350, the fixing portion 310 is adjustable in position relative to the peripheral portion 350 along the adjustment axis A352.

[0047] In the illustrated example, the adjustment means include notches 356, which are regularly spaced along at least one of the straight edges 352A or 352B of the opening 352, the notches 356 along the same edge forming a row 358 of notches. In the illustrated example, notches 356 are provided along each of the straight edges 352A and 352B, the peripheral portion thus comprising two rows 358 of notches 356. The notches 356 here have a rectangular profile and are provided by notches cut into the straight segments 354A and 354B. Two successive notches 356 are thus separated by a notch, a pitch between two successive notches 354 being equal to a length, measured parallel to the adjustment axis A352, of one notch and one notch.

[0048] The adjustment means also include teeth, which are formed on the fixing portion 310 and configured to cooperate, by complementary shape, with a portion of the notches 356, so as to prevent translational movement of the fixing portion 310 relative to the peripheral portion 350 along the adjustment axis A352 when the flange is in the engaged configuration. The teeth are then engaged in some of the notches 356. By extension, the adjustment means are also said to be in an engaged configuration.

[0049] Each tooth here has a profile corresponding to the notches between two successive notches 356. Preferably, the teeth have the same profile as the notches 356. In the illustrated example, several teeth are provided along each straight segment 332A and 332B of the fastening portion 310, forming rows of teeth. The teeth and the rows of teeth are not shown.

[0050] Thus, during the assembly of the flange 300, the position of the fixing portion 310 relative to the peripheral portion 350 along the adjustment axis A352 is adjustable incrementally, according to an adjustment step corresponding to the step between two successive notches 356. The adjustment step depends on the shape of the notches 356 and the teeth, which allows for finer adjustment compared to devices known in the prior art, in particular an adjustment independent of the size of the recess 312, which accommodates the bearing 22. In the illustrated example, the step between two successive notches 356 is 10 mm, compared to a diameter of the star-shaped bearing 22 of approximately 60 mm. Each row 358 of notches 356 has five notches, while each row of teeth has three teeth. It is therefore possible to choose between three different positions.

[0051] Advantageously, markings 337 are provided on the flange 300 to indicate to the installer the position in which to assemble the fixing portion 310 and the peripheral portion 350. The markings 337 are preferably alphanumeric characters, or even pictograms. In the illustrated example, the markings are a sequence of numbers "1-2-3".

[0052] More generally, it is understood that the position adjustment of the fixing portion 310 relative to the peripheral portion 350 is possible with a single row 358 of notches 356. The configuration with two rows 358 of notches is however preferred because it allows better absorption of the forces transmitted during the use of the installation 10, which reduces the risks of accidental breakage of the fixing part 310.

[0053] We now detail support 30, with reference to figures 4 à 6 .

[0054] The tenon plane P102 and the fitting plane P104 are coplanar with each other, the tenon 102 and the fitting 104 forming a bend. In other words, the fixing axis A102 is inclined relative to the fitting axis A104 at an angle α100°. The angle α100° is zero when the fixing axis A102 is aligned with the fitting axis A104. In the context of the invention, the angle α100° is non-zero. Typically, the angle α100° is between 10° and 90°, preferably between 20° and 70°, and even more preferably between 30° and 60°. In the illustrated example, the angle α100° is 45°. The leg 100 includes a front edge 108, which is located on a front side of the tenon 102, on an opposite side, along the fixing axis A102, of the fitting 104.

[0055] The flange 300 comprises, in addition to the fixing portion 310, an attachment portion 390, by which the flange 300 is configured to be fixed to the tenon 102. In the illustrated example, the flange comprises the peripheral portion 350 and the fixing portion 310, the attachment portion 390 being here a part of the peripheral portion 350. Of course, the principles of the invention are transposable to other flange structures.

[0056] The attachment portion 390 comprises two side walls 394A and 394B. The two side walls 394A and 394B are substantially parallel to each other, are arranged opposite each other and delimit between them a passage 396 for the tenon 102. The two side walls 394A and 394B define an insertion direction A396 of the attachment portion 390.

[0057] The tulip 200 comprises, in addition to the first clip 206 for assembly to the fitting 104, a second clip 210, which is configured to cooperate with a second orifice 398 provided on the flange 300, so as to prevent translational movements of the first sub-assembly 50 relative to the flange 300 parallel to the insertion direction A 396, when the tenon 102 is received in the passage 396. The support 30 is then in an assembled configuration, as shown in the figure 5 a) .

[0058] In the illustrated example, the second clip 210 includes an elongated elastic tab 212, which is connected at one end 212A to the rest of the tulip 200 and which includes, at its other end 212B, a bulge 214, which here has a cylindrical shape with a circular cross-section and a bevel 216. The second opening 398 has a shape complementary to that of the second clip 210, namely a cylindrical shape, configured to receive the bulge 214. The bevel 214 allows the tab 212 to be elastically deformed during the assembly of the first subassembly 410 to the flange 300. Advantageously, a stiffening rib 213 is provided along the elastic tab 212.

[0059] Assembling support 30 is therefore particularly easy and quick to implement, and requires no special effort. For example, an assembly method for support 30 comprises the following successive steps: a) fit the fitting 104 into the channel 204 of the tulip 200 until the first elastic clip 206 cooperates with the first orifice 106 provided on the fitting 104, so as to form the first sub-assembly 410, b) then, insert the tenon 102 into the passage 396 according to the insertion direction A396, until the second elastic clip 210 cooperates with the second orifice 398 provided on the flange 300, so as to form the support 30.

[0060] When the flange 300, the fitting 104 and the tulip 200 are assembled together, forming the support 30, the first elastic clip 206 holds the tulip 200 on the fitting 104, while the second clip 210 holds the first subassembly 410 relative to the flange 410.

[0061] The second clip 210 also includes an extension 218, which prolongs the second elastic clip 210. In the illustrated example, the extension 218 extends from the second end 212B of the elastic tab 212 and terminates in a widened portion forming a gripping portion 219. The gripping portion 219 advantageously has an overall flattened disc shape. Preferably, the gripping portion 219 is located farther from the first end 212A of the elastic tab 212 than from the second end 212B. This allows the user to elastically deform the elastic tab 212 by applying force to the gripping portion 219.

[0062] As illustrated in particular by figure 3 In the assembled configuration of the support 30, the gripping portion 219 extends out of the flange 300, so that it is possible for the user to press on the gripping portion 219 in such a way as to elastically deform the elastic tab 212 and disengage the bulge 214 from the second orifice 398. It is then possible to move the first subassembly 410 away from the flange 300, parallel to the insertion direction A396.

[0063] Advantageously, the gripping portion 219 features an inscription for the user, which is visible when the support 30 is in its assembled configuration. In the non-limiting example shown in the figures, the inscription is a sequence of alphanumeric characters, specifically "PUSH." The inscription "PUSH" indicates to the user where to press to disassemble the support 30. In an alternative not shown, the inscription is or includes a pictogram.

[0064] It is also particularly easy to disassemble the support 30. For example, a disassembly procedure for support 30 includes: press on the gripping portion 219, so as to elastically deform the elastic tab 212 and disengage the bulge 214 from the second orifice 398, then, while the bulge 214 is disengaged from the second orifice 398, remove the tenon 102 from the passage 396 in a direction opposite to the insertion direction A396.

[0065] It is then possible to interrupt the pressure on the gripping portion 219, to allow the second clip 210 to resume, by elastic return, a relaxed configuration.

[0066] With reference to the figure 5 a) The tulip 200 advantageously includes a second wall 220, which is arranged opposite the bottom 202C of the tulip 200, on one rear side of the bottom 202C, the rear side being oriented opposite to the front side. The second wall 220 and the bottom 202C together define the conduit 204 of the tulip 200. The second wall 220 and the bottom 202C are connected to each other by guides 222, which are configured to guide the fitting 104 inserted into the conduit 204, so that the fitting 104 is kept at a distance from the bottom 202C, providing a gap 224 between the fitting 104 and the bottom 202C. The gap 224 is therefore a portion of the conduit 204. The guides 222 here have a parallelepiped shape. When the fitting 104 is inserted into the conduit 204, the fitting 104 is guided by the guides 222, the parallel movement of the fitting 104 being a translational movement.

[0067] As illustrated in the figure 6a The gap 224 is configured so that, when the support 30 is in its assembled configuration, part of the attachment portion 390 is received in the gap 224, while the front face 302A of the flange 300 rests against the rear side of the tulip base. The tab 100, the tulip 200, and the flange 300 are thus supported by each other, plane upon plane, which contributes to the overall strength of the support 30.

[0068] The attachment portion 380 includes an opening 400, which is cut into the flange 300 and which delimits a front side 392A of the bottom wall 392, the passage 386 opening from the side of the rear face 302B of the flange 300 through the opening 400. The opening 400 is here a slot, which extends orthogonally to the insertion axis A396.

[0069] The flange 300 includes a stop, which is configured to bear against the lug 100 so as to limit the insertion movement of the tenon 102 in the passage 396, the lug 100 being in contact with the stop when the lug 100 is in the assembled position relative to the flange 300.

[0070] In the illustrated example, the stop is formed by a third wall 394C, which extends one of the two lateral walls 394A and 394B connecting the bottom wall 392 to the rest of the attachment portion 390. The third wall 394C, and by extension the stop, is arranged here so as to bear against the front edge 108 of the tenon 102. Other arrangements of the stop are, of course, possible. In an alternative not shown, the stop bears against an inner side of the bend formed by the fitting 104 and the tenon 102.

[0071] The second clip 210 is configured to cooperate with the second orifice 380 when the tab 100 is abutted against the third wall 394C. When the bracket 30 is used in an installation 10, as illustrated in the figure 1 , gravity tends to keep leg 100 against the third wall 394C.

[0072] Advantageously, the front edge 108 is interposed between two claws 109, the front edge 108 being set back, relative to the claws 109, along the fixing axis A102. The claws 109 are configured to cooperate, in particular by complementary shapes, with the third wall 394C, so as to limit assembly gaps when the support 30 is in the assembled configuration.

[0073] As in the illustrated example, each attachment portion 390 advantageously has a symmetrical shape with respect to a plane parallel to the adjustment axis A352. In particular, another orifice 399 is arranged symmetrically to the second orifice 398. Advantageously, the peripheral portion 350 has an overall symmetrical shape with respect to a plane parallel to the adjustment axis A352. Preferably, the attachment portions 310 are also symmetrical. Flanges 300 of the same type can thus be used to assemble the two supports 30 of the protective installation 10, thereby reducing the number of different spare parts.

[0074] A 30' support conforming to a second embodiment of the invention is shown in figures 7 à 9 In the second embodiment, elements analogous to those in the first embodiment bear the same reference numerals and function in the same way. The following primarily describes the differences between the first and second embodiments. If a reference numeral is mentioned in the description but not shown in a figure, or shown in a figure but not mentioned in the description, it refers to the same element as the one bearing the same reference numeral in the first embodiment.

[0075] With reference to the figure 7 a) The 30' support advantageously includes a 500 jumper, which is configured to be mounted on the 219 gripping portion. With reference to the figures 7b) et 7c ), the rider 500 includes a body 502 forming a cavity 504 for receiving the gripping portion 219. The cavity 504 has a mouth 506, which opens along a mouth axis A506, the gripping portion 219 being inserted into the cavity 504 by means of an insertion movement, which is a translational movement along the mouth axis A506.

[0076] The rider 500 advantageously features stops 508, which are located on the opposite side of the cavity 504 from the opening 506. The stops 508, thus formed in the bottom of the cavity 504, are configured to limit the insertion movement of the gripping portion 219. When the gripping portion 219 is received in the cavity 504 and resting against the stops 508, the rider 500 is in an engaged position, as illustrated in the diagrams. figures 7a And 8 .

[0077] The rider 500 advantageously includes lugs 510, which are formed on the body 502 and extend inward into the cavity 504. The lugs 510 are configured to cooperate with the gripping portion 219, particularly through complementary shapes, so as to maintain the rider 500 in the engaged position in the absence of external forces, as illustrated in the figure 8 a) . When the gripping portion 219 is inserted into the cavity 504, the lugs 510 deform elastically to accommodate the passage of the gripping portion 219 and then, once the rider is in the engaged position, the lugs 510 return to their initial shape by elastic return.

[0078] Advantageously, the jumper 500 includes at least one opening 512, which is provided in the body 502 and through which the cavity 504 opens outside the body 502. Each opening is configured to allow the user to see the gripping portion 219 received in the cavity 504 when the jumper 500 is in the engaged position, in particular to verify that the gripping portion 219 is properly supported against the stops 508.

[0079] Advantageously, the rider 500 includes support lugs 520. The support lugs 520 project from the body 502 parallel to the mouth axis A506. The support lugs 520 include a main lug 521, which is located on the front side 302A of the flange 300 when the support 30' is assembled and the rider 500 is in the engaged position, as illustrated in the figures 7 a) And 8 a ). The 30' support is then in a secure configuration.

[0080] Advantageously, cavity 504 opens, through at least one opening 512, on the front face 302A of the flange when the support 30' is in a secure configuration. The user can thus visually verify that the support 30' is correctly assembled even when the support 30' is part of a protective installation 10.

[0081] The main tab 521 includes a notch 522, one contour of which corresponds to a contour of the second hole 398 when the support 30' is in the secure configuration. Thus, the jumper 500 does not interfere with the bulge 214; in particular, the installation of the jumper 500 does not risk pushing the bulge 214 out of position.

[0082] The 520 support lugs include secondary lugs 524, which are located on the rear side 302B of the flange 300 when the support 30' is in the secured configuration, as illustrated in the figure 8 b) .

[0083] When the support 30' is in the secure configuration, the main tab 521 and the secondary tabs 524 are located on either side of the flange 300; in other words, the bracket 500 straddles one edge of the flange 300. Preferably, the main tab 521 and the secondary tabs 524 rest on the front and rear faces 302A / 302B of the flange 300. In other words, the bracket 500 is clamped onto the flange 300.

[0084] During the assembly of the 30' bracket, if the bulge 214 is not correctly received in the second hole 398, then it is not possible to insert the gripping portion 219 into the cavity 504 up to the stops 510. Installing the jumper 500 allows the installer to confirm that the second clip 210 is correctly received in the second hole 398. The jumper 500 thus serves as a visual indicator of the correct assembly of the 30' bracket. Simultaneously, once the 30' support is in the secure configuration, the support lugs 520 cooperate with the flange, so that the jumper 500 holds the bulge 214 in the second opening 398, thus preventing accidental disassembly of the 30' support, even when the user presses on the gripping portion 219. In other words, the jumper 500 serves to secure the assembly of the 30' support. The 30' support is easy to assemble and disassemble by hand and without tools, while remaining secure.

[0085] Assembly steps for the 30' stand are described, with reference to figures 9 a) et 9 b ). Thus, the assembly of the 500 jumper includes: Provide the leg 100, the tulip 200 and the flange 300 in the assembled configuration, position the rider 500 in front of the gripping portion 219, the mouthpiece 506 being oriented towards the gripping portion, as illustrated in the figure 9 a) The main lug 521 is located on the front side 302A of the flange 300. Bring the rider 500 and the rest of the support 30' together in a translational movement parallel to the mouth axis A506, so as to insert the gripping portion 219 into the cavity 504, as illustrated in the figure 9 b) The translational movement continues until the gripping portion comes to rest against the stops 508. The support 30' is then in the secure configuration, as illustrated in figures 7 a) And 8 a) à 8 c) .

[0086] The embodiments and variants mentioned above can be combined with each other to generate new embodiments of the invention as defined by the claims.
