Description

technical field

[0001] The present invention relates to the field of lighting and luminaires.

[0002] The object of the present invention relates more particularly to a support device for a luminaire intended to be installed on a wall equipped with an electrical supply. Support devices are disclosed, for example, in GB 2 064 885 A, US 11 435 072 B1, EP 3 217 061 A1, US 2002 / 197910 A1 and CN 218 153 831 U.

[0003] The object of the present invention also relates to a luminaire intended to be installed on a wall using a support device.

[0004] For the purposes of this invention, "wall" means in the entire description that follows any type of wall constituting a vertical or mansard wall or a ceiling, the wall being for example made of solid or hollow brick, breeze block, cellular concrete, plasterboard, wood and wood derivatives or even stone.

[0005] The present invention will find many advantageous applications both for the occupants of a dwelling and for electricians or lighting engineers. Technological background

[0006] Many lighting installers, whether private individuals such as homeowners or professionals such as electricians or lighting specialists, are faced with installing a light fixture on a wall or ceiling equipped with an electrical supply.

[0007] In the first installation scenario, the wall receiving the light fixture to be installed is devoid of any means of fixing and electrical connection; only wires come out of the wall.

[0008] In a second installation scenario, the wall is fitted with an electrical junction box containing a cable or electrical wires. This box is quite basic, and the installer must connect the wires to the light fixture via a screw terminal block, for example.

[0009] In both cases, there is a risk of electric shock if the person forgets to turn off the power. Furthermore, after repeated use, the installation can deteriorate, making new connections difficult. In the first installation scenario, it is also difficult to neatly arrange the electrical wires to make them inaccessible once the light fixture is installed.

[0010] For several years now, lighting connection devices called DCLs have allowed light fixtures to be connected to an electrical circuit. It is essentially a standard electrical outlet, albeit in a compact format. The DCL is internationally standardized by the IEC under the reference IEC-619951. This device can be completely recessed into the ceiling or wall, eliminating any protruding wires, and making the electrical connection very simple and secure. In France, the DCL has been mandatory for new construction and renovations since October 1, 2001, according to the NF C 15-100 standard. In a third installation scenario, the wall itself acts as a cover or the top surface of a lighting connection device (DCL).

[0011] Faced with these various installation scenarios, installers are often required to choose a light fixture specifically designed for a particular situation, or to adapt an existing fixture for an unforeseen installation. This can result in mechanical strength that is not always satisfactory, or a finish that reveals technical components such as the cover of a DCL (lighting connection device). Furthermore, many installation steps are carried out at the wall or ceiling level, including electrical connections, adjustments, and mechanical fixing. Summary of the present invention

[0012] The present invention aims to improve the current situation.

[0013] One object of the present invention is to solve at least one of the problems of the technological background described above.

[0014] Another object of the present invention is to offer an installer a support device for a luminaire intended to install a luminaire in all the aforementioned cases with real ease of installation.

[0015] According to a first aspect, the invention relates to a support device for a luminaire intended to be installed on a wall equipped with an electrical power supply; the device comprises a base, a cover mounted on the base, and at least one first electrical connector; the base comprises: a support face extending in a determined plane configured to be in contact with the wall; a first fixing means configured to allow fixing by screwing of a threaded element without tools; a first opening configured to allow the passage of first electrical wires and a second electrical connector; a first housing receiving at least one first electrical connector configured to connect the first electrical wires to second electrical wires of an electrical cable of the luminaire;a compartmentalized structure comprising ribs extending perpendicularly to the plane and arranged circumferentially around a second housing and along at least one axis passing through the second housing to define gaps between ribs, each gap forming a portion of the path, the compartmentalized structure being capable of receiving and guiding the electrical cable through a set of path portions forming a determined path to set a length of the electrical cable by arranging the electrical cable in the compartmentalized structure; and a first contact surface arranged relative to a second contact surface of the cover so as to hold the electrical cable in position relative to the support device by deformation and compression.

[0016] This support device facilitates the wall mounting and electrical connection of the light fixture to the electrical installation. Indeed, thanks to the combination of these technical means, the installer has a tool that allows them to prepare the installation of a light fixture without having to face the wall, thus adjusting the length of the light fixture's cable and preparing the electrical connections before installing the fixture on the wall without the need for tools.

[0017] According to one variant of the support device, each gap is configured to allow an overlap of at least two layers of the electrical cable.

[0018] Advantageously, the compartmentalized structure is configured to ensure at least three turns of winding of the electrical cable.

[0019] The length of the electrical cable exiting the support device can be adjusted by successively winding the cable in the compartmentalized structure.

[0020] According to another variant of the support device, the ribs have protrusions configured to hold the electrical cable in a coiled position.

[0021] According to an additional variant of the support device, the ribs have fillets at their base, the fillets of the same gap forming in pairs a groove suitable for guiding the electrical cable into the gap.

[0022] The electrical cable length setting is thus preserved during handling of the support device or during adjustments on the ceiling, the electrical cable being held in the desired adjustment position.

[0023] According to one embodiment, the threaded element is a screw with a hexagonal or square head that is blocked from rotation in a cavity in the base, the cavity having a shape complementary to the shape of the screw head.

[0024] The installer is able to screw the support device into position without using a tool, simply by rotating the base with their hands.

[0025] According to yet another variant, the support device includes a second means of fixing comprising at least two openings in the base, which are configured for fixing the support to the wall by screwing it.

[0026] The second method of fixing allows the support device to be mounted using screws incorporated into recessed boxes or using screws driven directly into the wall or by doweling.

[0027] Advantageously, the at least two openings are each formed by a groove of a determined width communicating with at least one circular orifice of a diameter greater than the width guaranteeing the passage of a screw head, already present in the wall, through the circular orifice and a tightening under the screw head in the groove.

[0028] The grooves allow installation on flush-mounting boxes of different diameters with different fixing center distances and do not require the installer to be highly precise in placing the screws when fixing with screws directly into the wall.

[0029] According to another variant of the support device, the first and second contact surfaces together form a baffle.

[0030] The baffle holds the light fixture's electrical cable in position by compressing and deforming it. The cable is thus held in place by the support device, even when a tensile force is applied to it.

[0031] According to yet another embodiment, the base has protuberances on an outer surface capable of holding in position a rosette covering the base.

[0032] The aesthetic finish of the support device is achieved by the rosette which is thus easily installed, the rosette being simply placed in position and held firmly by the base.

[0033] According to an additional embodiment, the base has at least one storage space configured to receive installation elements not used during an assembly operation.

[0034] The installer is thus able to store unused installation elements and will find them again when dismantling the support device.

[0035] According to a second aspect, the invention relates to a luminaire comprising a support device as described above according to the first aspect of the invention.

[0036] According to a third aspect, the invention relates to a kit or assembly comprising a luminaire and a support device as described above according to the first aspect of the invention.

[0037] Through its various structural and functional aspects as described above, the present invention provides installers with a simple and practical tool that allows for the quick and easy fixing of a light fixture in various installation scenarios. Brief description of the figures

Description of the implementation methods

[0039] A luminaire support device intended for installation on a wall with an electrical supply, as well as examples of luminaires including such a support device, will now be described in the following sections with joint reference to figures 1 to 14 .

[0040] The same elements are identified with the same reference symbols throughout the description that follows.

[0041] According to a particular and non-limiting example of an embodiment of the invention, a support device 100 for a luminaire intended to be installed on a wall supplied with an electrical supply comprises a base 10, a cover 20 mounted on the base and at least one first electrical connector 30.

[0042] According to this example and as illustrated in figure 1, base 10 and hood 20 are for example parts made of a thermoplastic material of the type PC (polycarbonate), PP (polypropylene), ABS (Acrylonitrile Butadiene Styrene), PLA (Polylactic acid), PETG (Polyethylene Terephthalate Glycolized), or PA (polyamide) whose shape is obtained by injection molding or by additive printing for example FDM (from the English “Fused Deposition Modeling”, in French “modelage par dépôt en fusion”), SLS (from the English “Selective Laser Sintering”, in French “Sinterttage Sélectif par Laser”), SLA (Stereolithography) or MJF (Multi Jet Fusion).

[0043] Of course, any man in the trade understands that such parts can also be obtained by other manufacturing processes, for example by compression molding of a thermosetting material.

[0044] The installer wishes to install a luminaire 200 on a specific wall using the support device 100. The wall has been described previously under three installation scenarios. As a reminder, in the first installation scenario, the wall receiving the luminaire 200 has no means of fixing or electrical connection; only cable 320 or wires 321 protrude from the wall.

[0045] In the second installation case, the wall is equipped with an electrical recessed box in which there is a 320 cable or 321 electrical wires.

[0046] In a third installation case, the wall is then a cover 300 or a top face of a lighting connection device (DCL) having a standardized connector into which it is enough to plug a second connector 310 compatible with the connector of the installation.

[0047] The installer has, following this example and as illustrated in figure 9 , of a modular "pendant", consisting of a 220 electrical cable connected to a 230 socket onto which a 240 bulb is connected, the 230 socket being able to optionally support a 250 lampshade as illustrated in Figure 10 .

[0048] The 230 socket allows the connection of a 240 standard type bulb, such as an E27 or E14 screw-in bulb, a B22 bayonet bulb, or GU10, S14d, or G9 type bulbs. These bulbs are, for example, filament, halogen, or LED (light-emitting diode). Their energy consumption is taken into account when choosing the cross-section of the secondary electrical wires 221 that make up the 220 electrical cable. Thus, the cross-section of these secondary electrical wires 221 is, for example, 0.5, 0.75, 1.0, or 1.5 mm².

[0049] The lampshade 250 is ornamental and can have different appearances, shapes, and materials. Its mass is taken into account in the sizing of the support device 100 in order to support the total mass suspended via the electrical cable 220.

[0050] According to another example of luminaire 200, the 220 electrical cable is connected to a complete luminaire, having for example light sources such as integrated LEDs and / or an electronic circuit for transformation and / or control of the lighting.

[0051] The installer also has a ceiling rose 210, an aesthetic component made of various materials such as plastic or metal, which can be bare, coated, or painted. This rose comes in different shapes depending on the style of the luminaire 200; its shape is, for example, relatively simple, as illustrated in figure 1 It features diamond-shaped faces as illustrated in figure 11or imitates ornamental moldings as illustrated in Figures 12 and 13 According to these examples, the 200 luminaire comprises a single pendant, but it can also comprise several pendants as illustrated in figure 14 .

[0052] According to another example of luminaire 200, the latter has an additional part constituting a rigid sleeve 260, illustrated in figure 8 This allows the 200 luminaire to be installed as a wall-mounted fixture without the pendant coming into contact with the wall. This rigid sleeve is, for example, fixed securely to the base 10 or the cover 20, or may even be part of one of these two components.

[0053] Initially, the installer determines the installation height of the luminaire 200 and then the length of its electrical cable 220. This length is defined relative to the location of the ceiling rose 210, with the electrical cable 220 passing through the ceiling rose 210 via an opening 211. To mark the final length of the electrical cable 220 extending from the ceiling rose 210, the installer places a marker on the electrical cable 220. This marker could be, for example, an additional piece clipped onto the luminaire's electrical cable 220. The marker is positioned on the inside of the ceiling rose 210, allowing the ceiling rose 210 to slide freely along the electrical cable 220, for example, to rest against the socket 230 while the luminaire 200 is being installed on the wall.

[0054] The installer takes hold of the cover 20 and passes the free end of the luminaire's electrical cable 220 through a designated opening 22 in the cover 20. He then takes the base 10, positions the electrical cable 220 opposite a second outlet 15 in the base 10, inserts it, and then winds the electrical cable 220 into a compartmentalized structure 14a in the base 10, as illustrated in the figure. figure 6The term "winding" is to be understood here in a broad sense. Indeed, winding does not simply consist of arranging the 220 electrical cable in circles or a regular spiral; rather, winding refers to the arrangement of the 220 electrical cable within the compartmentalized structure 14a, following a predetermined path through different sections positioned within the compartmentalized structure 14a without any particular rule. The winding direction may change along the predetermined path, for example, and the path may, as another example, include sections that do not describe a circle or a spiral. Furthermore, depending on the specific embodiment, the predetermined path may lie in a plane or in space.

[0055] To this end, the base 10 comprises a compartmentalized structure 14a including ribs 14c extending perpendicularly to a plane P defined by a bearing surface 11 in contact with the wall receiving the support device 100. The ribs 14c are arranged circumferentially around the second housing 15 and along at least one axis A2 passing through, or traversing, the second housing 15, and parallel to the plane P to define gaps 14d between ribs 14c. In the case where the base 10 has a circular contour, the second housing 15 is, for example, placed at the center of the circular contour of the base 10, and an axis A2 passing through the second housing 15 is then a radial axis of the circular contour of the base 10.Each gap 14d forms a portion of the path, and the compartmentalized structure 14a is then able to receive and guide the electrical cable 220 through a series of path portions forming a specific path to set a length of the electrical cable 220 by winding the electrical cable 220 within the compartmentalized structure 14a. It should be noted that the paths are different for inserting an electrical cable 220 of a different length, and several paths can allow setting the same cable length depending on the configuration of the ribs 14c. Thus, the electrical cable 220 follows a specific path through the compartmentalized structure 14a, from the second slot 15 to a first slot 13 configured to receive at least one connector 30. The electrical cable 220 is guided and held between ribs 14c, that is, in the gaps 14d, along at least one portion of the path.

[0056] In this example, the compartmentalized structure 14a is made using openwork ribs 14c, guiding the electrical cable 220. The ribs 14c are arranged in the form of arcs of concentric circles, the center of which coincides with the center of the second housing 15. The distance separating the ribs 14c, i.e. the width of a gap 14d separating them, is, according to a particular embodiment, defined so as to allow the electrical cable 220 to pass freely, thus avoiding any effort on the part of the installer placing the electrical cable 220 in the compartmentalized structure 14a.According to another particular embodiment, the spacing between two ribs 14c, i.e. the passage width in a gap 14d, is less than the outside diameter of the electrical cable 220, for example by a few tenths of a millimeter (mm), so as to keep the electrical cable 220 in position in the gap 14d without requiring significant effort from the user to insert the electrical cable 220 into the compartmentalized structure 14a.

[0057] In this example, to allow for a wide range of adjustment for the length of the 220 electrical cable, each gap 14d is configured to allow for the overlapping of at least two layers of the 220 electrical cable. The compartmentalized structure 14a then makes it possible to offer a plurality of paths comprising sections of the path located in planes parallel to plane P and separated in pairs by a height defined by the outer diameter of the 220 electrical cable. In this way, the adjustment range is doubled or even tripled. Thus, if it is possible to wind 30 cm of 220 electrical cable in the compartmentalized structure 14a per layer and per turn, then it is now possible to wind approximately 60 cm or even 90 cm of 220 electrical cable in overlapping layers per turn in the compartmentalized structure 14a.The electrical cable 220 is, for example, arranged along a path passing several times through the same gap 14d and passing or not through all the gaps 14d. The path followed by the electrical cable 220 through the compartmentalized structure 14a is then defined in three dimensions, the numerous possible choices of path segments allowing for both fine and large-amplitude adjustment of the length of the electrical cable 220.

[0058] In this example, the compartmentalized structure is also configured to ensure at least three turns of winding for the 220 electrical cable. Thus, if one turn represents 12 cm of electrical cable, three turns represent approximately 40 cm of adjustment for the length of the 220 electrical cable. The arrangement and thickness of the ribs 14c then allow for a large volume of 220 electrical cable within the compartmentalized structure 14a. In other words, it provides a large storage capacity for the 220 electrical cable thanks to an increase in the density of the 220 electrical cable or the volume occupied by the 220 electrical cable. Thus, for a cable with a diameter of 10 mm and ribs with a thickness of 3 mm, the 220 electrical cable occupies up to 60% of the volume comprising the compartmentalized structure 14a while being guided within this compartmentalized structure 14a.

[0059] Since the ribs 14c are perforated, it is also possible to create paths other than simple regular windings. This means that instead of winding the cable along the entire path provided in the compartmentalized structure 14a, the path of the electrical cable 220 within the compartmentalized structure 14a can be adapted to more precisely adjust the length of the wound electrical cable 220, for example, by making partial turns. Perforating the ribs 14c of the compartmentalized structure 14a also increases the cable density of the electrical cable 220 by reducing the volume occupied by the ribs 14c within the compartmentalized structure 14a.

[0060] In another embodiment, the support device 100 is designed to connect several 220 electrical cables, for example, 2, 3, or 5 220 electrical cables. Each 220 electrical cable is then positioned between a single first slot 13 and a second output slot 15 assigned to it. The base 10 then has several compartmentalized structures 14a, arranged so that each 220 electrical cable can be wound around a second output slot 15 assigned to it within its own compartmentalized structure 14a. Of course, it is also possible to construct a base 10 with a single compartmentalized structure 14a, arranged so that each second slot 15 assigned to a 220 electrical cable is located inside the compartmentalized structure 14a.The various 220 electrical cables then run through the same compartmentalized structure 14a which they share, using different paths so as to adjust each of the 220 electrical cables to the desired length.

[0061] In this example, and as illustrated in figure 6The ribs 14c each have a protrusion 14b configured to hold the electrical cable 220 in a coiled position. The protrusions 14b are located at the entrance of each gap 14d formed between two ribs 14c. The cross-section of this passage at the entrance of the gap 14d is then reduced so as to be less than the diameter of the electrical cable 220. Thus, when inserting an electrical cable 220 into a gap 14d, the installer forces the electrical cable 220 behind the protrusions 14b; the ribs 14c thus allow the electrical cable 220 to pass through by deforming and then returning to their resting position, holding the electrical cable 220 in place in the gap 14d formed by the ribs 14c of the compartmentalized structure 14a.

[0062] According to this example, the ribs 14c have fillets 14e at their base. These fillets 14e reinforce the ribs 14c and prevent them from breaking at their base when the electrical cable 220 is inserted. The fillets 14e of the same gap 14d, that is to say fillets 14e facing each other, form in pairs a groove 14f suitable for guiding the electrical cable 220 in the gap 14d.

[0063] This cable length adjustment operation, performed before the installation of the support bracket 100 on the wall, allows the installer to easily adjust the cable length without being in an uncomfortable position, for example, when the wall is a ceiling. The installer does not have to work with their arms raised but can instead work seated, with the support bracket 100 placed on a table.

[0064] Once the 220 electrical cable is positioned, the installer strips it, revealing the second 221 electrical wires that make it up. He also strips the ends of the 221 electrical wires to obtain bare electrical conductors, which he places in a terminal block of the connector 30 configured to connect the first 321 electrical wires of the installation to the second 221 electrical wires.

[0065] The first 321 and second 221 electrical wires are of flexible, rigid, or multi-strand type. The first 321 wires are connected to the second 221 wires via at least one 30 connector of screw, automatic, or lever type.

[0066] In this example, and as illustrated in figure 5 , 3Connectors 30 are arranged in a first housing 13 that receives them. These connectors 30 are removable to facilitate electrical connections and are held in position once the cover 20 is in place. The number of three connectors is related to the number of phases to be connected; there are three to connect phase wires, neutral wires, and earth wires corresponding to the connection of a Class 1 electrical luminaire 200, i.e., one requiring earthing. The number of connectors could be, for example, two if the luminaire 200 is Class 2, i.e., it does not require earthing or equipotential bonding because it has double electrical insulation. Similarly, connectors 30 are not always connected to electrical wires; it is therefore possible to have three connectors 30 but only two phases: one phase wire and one neutral wire.

[0067] In this example, the connector 30 used is a lever type. This type of connector is compatible with all the wire types described previously. The installer has a lever that allows a wire conductor to be freely inserted into the terminal block when the lever is in the open position, and allows a wire conductor to be released from the terminal block during removal. Conversely, in the closed position, the lever releases a spring that grips the wire conductor, holding it in place and creating an electrical contact between the terminal block of connector 30 and the wire conductor.The connector 30 has a determined number of inputs per phase, for example 2 inputs if it is a matter of connecting a single first wire 321 of the same phase to a single second wire 221 of that same phase, or several inputs in the case of a branch connection, that is to say in the case where several first wires 321 are of the same phase and need to be connected together, or in the case where the luminaire has several cables 220 associated with several pendants, for example three pendants as illustrated in the . figure 14 .

[0068] In the case where the installation is done on a DCL, the installer also connects each first electrical wire 321 of an electrical cable 320 connected to a DCL plug 310 to a connector 30.

[0069] The installer then positions each connector 30 in the first slot 13 provided for this purpose. To hold the electrical cable 220 and each connector 30 in position, the installer slides the cover 20 along the electrical cable 220 and then presents it to the base 10, the second slot 15 being located opposite the opening 22.

[0070] In this example, and as illustrated in figure 4 The cover 20 is partially inserted by vertical translation into the base 10, a vertical axis A1 being defined as normal to a plane P coinciding with the bearing face 11 of the base 10, the bearing face 11 being the face that will be in contact with the wall once the support device 100 is installed and passing through the center of the second housing 15, as illustrated in figure 2Once the cover 20 is against the base 10, i.e., once a lower face 21 of the cover 20 is in contact with a face defining the bottom of the second housing 15, the installer rotates the cover 20 a quarter turn around the vertical axis A1, with fins 23 fitting into the complementary shapes made in the base 10. To facilitate the locking operation of the cover 20 in the base 10 by rotation, the installer has gripping areas 24 to facilitate the operation. To lock the cover 20 in its final position, a lug 25 is placed on one of the faces of the cover 20, the lug 25 fitting into an additional housing 102 provided in the base 10. The installer is then informed of the correct positioning of the cover 20 on the base 10 when he feels, by force feedback, that the lug 25 has reached its housing 102.

[0071] Other methods of attaching the cover 20 to the base 10, not shown here, are also possible, such as clipping the cover 20 onto the base 10 or screwing it in place. The installer then only needs to apply pressure to secure the cover 20 to the base 10 or tighten at least one screw.

[0072] In this example, placing the cover 20 on the base 10 results in a class 2 subassembly, as the conductive parts of the assembled assembly are protected: by electrical cables 320 and 220 having two insulating sheaths, those constituting the outer sheaths of the cables and those constituting the sheath of each electrical wire 321, 221, by the sheath of each electrical wire 321, 322 and an envelope comprising the cover 20 and the base 10, and / or by a connector 30 housed under an envelope comprising the cover 20 and the base 10. In addition, in this example the support device 100 includes three first electrical connectors 30, one of which serves for grounding the luminaire 200, the support device 100 is thus compatible with any luminaire 200 of class 1 or 2.

[0073] In this same example, once the cover 20 is mounted on the base 10, the electrical cable 220 of the luminaire is locked, a first contact surface 16 of the base 10 arranged in relation to a second contact surface 21 of the cover 20 holds the electrical cable 220 in position by deformation and compression in relation to the support device 100.

[0074] The first contact surface 16 is made in the form of a rib, placed on the path of the electrical cable 220 in the compartmentalized structure 14a. This rib is placed at the entrance of the second housing 15, the electrical cable 220 always passing through this place.

[0075] The second contact surface 21 coincides with the lower surface of the hood 20.

[0076] According to this example and as illustrated in figure 3The first 16 and second 21 contact surfaces are offset. A first support point between support surface 16 and the electrical cable 220, and a second support point between support surface 21 and the electrical cable 220, are located on the same plane perpendicular to plane P and passing through the vertical axis A1, at different distances from the vertical axis A1. The first 16 and second 21 contact surfaces together form a chicane. The first and second support points are separated by a distance greater than the diameter of the electrical cable 220, forcing the electrical cable 220 to follow a path formed by the chicane, deforming but without being severed. The integrity of the electrical cable 220 is thus preserved; the electrical cable 220 is nevertheless held in place by the assembly formed by the base 10 and the cover 20.

[0077] The deformation of the electrical cable 220 is generated when the cover 20 is mounted on the base 10. The installer pushes the cover 20 towards the base 10, thus compressing the cable. Once the cover 20 is in position, the pressure is maintained by the fins 23 of the cover 20, which are positioned in a complementary groove in the base 10. The mechanical strength of the electrical cable 220 against tensile stress is thus ensured by the deformation of the electrical cable 220 as it passes through the resulting baffle.

[0078] To secure the assembly thus created by the installer to the wall, the installer removes a fixing hook, if the DCL (lighting connection device) is equipped with one. This hook is then placed in a designated slot on the base 10, which has at least one storage space configured to hold installation components not used during assembly, thus preventing the loss of any of these components. For example, a space is available between the base 10 and the rosette 210, and a retaining device such as a clip is placed on the base 10 to receive the DCL fixing hook. The installer can then easily locate it when replacing the support device 100.

[0079] According to this example and as illustrated in figure 3To fix the support device 100 onto the DCL cover 300, the base 10 includes a first fixing means configured to allow a threaded element 40 to be screwed in without tools. The installer first inserts a threaded element 40 into the base 10 before connecting the electrical cable 220 and fitting the cover 20. The housing 17 that receives the threaded element is sealed once the electrical cable 220 and the cover 20 are in position.

[0080] The diameter and pitch of the threaded element 40 are similar to those of the previously removed DCL hook. These dimensions are common for DCL installations, as such hooks are frequently used in conjunction with standardized flush-mounting boxes like the one described in the introduction. These dimensions for the threaded element thus provide sufficient tensile strength, the applicable tensile force being similar to that applied to the hook.

[0081] In this example, the threaded element 40 is a hexagonal head screw that is rotationally locked in a cavity 17 of the base 10, the cavity 17 having a shape complementary to the shape of the screw head. It should be noted that a square head shape is also suitable; the cavity 17 would then be of a correspondingly appropriate square shape.

[0082] This embodiment is not the only possible one; any person skilled in the art can propose other solutions such as directly manufacturing the threaded element 40 in the main body of the base 10, or molding or printing the base 10 directly onto the threaded element 40, the threaded element 40 then being embedded in the base 10. Among these particular embodiments of the first fastening means, the first method has the advantage of allowing the threaded element 40 to be separated, thus making it removable and not a hindrance when it is not used during the installation of the support device 100.

[0083] According to this example, the mounting of the base 10 on the wall is done without the use of any tools; an installer simply needs to turn the base 10 by hand so that the bearing face 11 comes into contact with the wall by screwing the threaded element 40, the threaded element 40 being screwed into a part of a recessed box provided for this purpose or into a dowel previously placed in the wall.

[0084] Tool-free screwing by simply rotating the base 10 by hand is very easy. This is because the base 10 has a significantly larger width or diameter than a screwdriver handle. For example, the base 10 is available in widths or diameters of 70, 90, 120, or 150 mm. The torque obtained by rotating the base 10 is therefore much greater than that obtained with a screwdriver or a tool of a similar size to a screwdriver handle. The installer can then easily secure the base 10 to the wall.

[0085] The strong torque generated by the rotation of the base 10 during the screwing operation of the threaded element 40, as well as the pressure exerted by the threaded element 40 along its axis of rotation, is transmitted into the areas of the base 10 in contact with the threaded element 40. Thus, according to a particular embodiment example, ribs are made in the base 10 around the cavity 17 in order to stiffen this part of the base 10 and make it more solid.

[0086] The rotation of the base 10 ends when the support face 11 is in contact with the cover 310 of the DCL and a first opening 12 of the base 10 is positioned opposite the connector of the DCL, the first opening 12 being configured to allow the passage of first electrical wires 321 and a second electrical connector 310. The installer is then able to insert the second electrical connector 310, here a DCL plug, through this first opening 12.

[0087] In order to conform to the shape of the wall and to accept defects in flatness, the base is for example able to deform to follow the surface of the wall.

[0088] According to another example (not shown), the base includes on its rear face an elastic part, for example, a seal made of an elastomeric material such as rubber, silicone, or polyurethane. This elastic part is capable of deforming in order to fill, for example, irregularities on the surface of the wall on the order of a few millimeters, for example, 1, 2, or 3 mm, thus providing a seal at the junction between the base 10 and the wall. According to a first particular embodiment of the elastic part, it is inseparable from the base 10. It is, for example, produced by overmolding, that is, injection molding of a second material directly onto a main body of the base 10, thus making the main body of the base 10 and the elastic part a single unit. According to a second particular embodiment of the elastic part, it constitutes a separate part from the base 10.This elastic part is then a seal, which is for example toroidal in shape and which is housed in a groove made in the bearing face 11 of the base 10. Such an toroidal seal is for example a commercially available seal, which facilitates its supply and allows for a wide choice of size, shape and material to meet different needs determined according to the type of wall and the environment in which the support device 100 including this seal is placed.

[0089] According to this example and as illustrated in figure 6The base 10 has protrusions 19 on its outer surface designed to hold a rosette 210 in position, which covers the base 10. This rosette 210 serves a decorative function, concealing the base 10, the cover 20, the various fasteners, at least one connector 30, and the electrical cables 320 and 220. The rosette 210 is held in position by the base 10. The rosette has no mechanical action; since the base 10 is fixed to the wall and the other elements of the support device 100 are fixed to the base 10, a very robust assembly is not required. For example, it can be pressed onto the base 10, thus bearing against the protrusions 19, or clipped onto the base 10.

[0090] In the case where the installation does not include DCL, the mounting of the support device 100 on the wall is different.

[0091] In this example, and as illustrated in figure 6The support device 100 includes a second fastening method. The base 10 has two openings 18, which are configured for screwing the support 10 to the wall. These two openings 18 are designed to allow the passage of a screw shank and tightening under the screw head. Thus, in the absence of a dedicated fixing on or in the wall, the installer attaches the support device 100 to the wall using a conventional fastening method. For example, they simply drill holes in the wall, insert a wall plug suitable for the wall type, and then fix the base 10 of the support device 100 by screwing screws through the openings 18.

[0092] According to this example, each of the two openings consists of a groove 18a of a specific width communicating with at least one circular hole 18b with a diameter greater than the width. This hole allows a screw head to pass through the circular hole 18b and is then tightened under the screw head in the groove 18a. This type of opening 18 is commonly called a buttonhole. It allows the installer to fix the support device 100 to the wall without completely removing any existing screws on or in the wall.

[0093] For example, if the wall has a recessed box with two fixing screws spaced 47, 60, or 71 mm apart, the installer begins by partially loosening the screws to remove them from the wall. The distance between the wall and the underside of a screw head must be greater than the thickness of the base 10 around the groove 18a. The installer then passes one screw head through a circular hole 18b and moves the base 10 so that a second circular hole 18b is aligned with the head of a second fixing screw. Once all the fixing screws have passed through the openings 18, the installer moves the base 10 so that each screw head is aligned with a groove 18a, and then tightens the screws to secure the base 10 in position on the wall.

[0094] Once the base is fixed to the wall, the installer retrieves the power supply. This is in the form of an electrical cable 320 or electrical wires 321. The installer grasps these and passes them through the first opening 12, which is designed to allow the support device 100 to be used with a power supply consisting of wires or a cable that are directly accessible, emerging from the wall, or located inside a recessed box in the wall. The shape of the first opening 12 is thus designed to allow the passage of several electrical wires 321, either free or contained within an electrical cable 320. For ease of installation, the shape of the first opening 12 is wider than necessary, thus providing play and freedom in positioning the base 10.The installer strips the electrical cable 320 and the electrical wires 321 if necessary and connects them to each first electrical connector 30.

[0095] Note that if several electrical cables 320 are present, or several electrical wires 321 of the same phase are present, the first connectors 30 can be adapted for tapping. The support device 100 then incorporates connectors with multiple inputs for each phase.

[0096] It should also be noted that in order to obtain a class 2 assembly and in the case where the installation has 321 electrical wires and not a 320 electrical cable, the installer adds sheaths on each 321 electrical wire in order to obtain double insulation of the conductors.

[0097] The installer then places the cover 20 onto the base 10, thus holding each element in position. He then slides the rosette along the electrical cable 220 until it covers the support device 100.

[0098] The installer thus has a practical tool suitable for numerous installation scenarios. This versatile solution allows them to easily mount different light fixtures with great ease.
