Description

Technical Field

[0001] The utility model relates to the field of lighting and lamps.

[0002] The utility model particularly relates to a supporting device for a lamp installed on a wall provided with a power supply.

[0003] The utility model also aims at a lamp installed on a wall by means of a supporting device.

[0004] For the purposes of the present invention, throughout the specification, a wall refers to any type of wall constituting a vertical or attic wall or a ceiling, for example made of solid or hollow bricks, cement bricks, porous concrete, gypsum board, wood and wood derivatives or stone.

[0005] The present invention finds numerous applications that are equally beneficial to residential dwellers and electricians or lighting engineers. Background Art

[0006] Many light fixture installers, whether individuals such as domestic residents or professionals such as electricians or lighting engineers, will encounter the task of installing a light fixture on a wall or ceiling where a power source is provided.

[0007] In a first installation situation, the wall receiving the luminaire to be installed is devoid of any electrical fixing and connection means, only electrical wires extending from the wall.

[0008] In the second installation situation, the wall is equipped with an electrical recessed box in which the cables or wires are located. Such a box is rather crude and the installer should connect the wires to the lamp, for example by means of screw terminals.

[0009] In both cases, there is a risk of electric shock if the personnel forget to cut off the current. In addition, after multiple operations, the installation can deteriorate, which makes it difficult to make new connections. In the first installation case, it is also difficult to store the wires after the lamp is installed so that they are inaccessible.

[0010] For many years, the lamp connection device known as DCL has allowed lamps to be connected to electrical circuits. It involves a reduced form of a real electrical socket. The DCL is internationally standardized by the IEC according to IEC-619951. The device can be completely embedded in the ceiling or wall, without any protruding wires, and the electrical connection is very simple and safe. In France, DCL has been mandatory for new construction and renovation since October 1, 2001, according to the NF C15-100 standard. In the third installation case, the wall is the cover or top surface of the lamp connection device (DCL).

[0011] Faced with these different installation situations, installers are often forced to choose luminaires specifically adapted to this or that situation, or to retrofit existing luminaires for unforeseen installation situations. The result is that the mechanical strength is not always satisfactory, or the surface treatment exposes technical parts, such as the cover of the DCL. In addition, many installation steps are carried out at the wall or ceiling, such as electrical connections, adjustments and mechanical fixings. Utility Model Content

[0012] The utility model aims to improve the current situation.

[0013] The purpose of the present invention is to solve at least one of the problems in the above-mentioned background technology.

[0014] Another object of the utility model is to provide the installer with a support device for a lamp, which is designed to install the lamp in all the above-mentioned situations and has real installation comfort.

[0015] According to a first aspect, the utility model relates to a support device for a lamp mounted on a wall provided with a power supply, the device comprising a base, a cover mounted on the base and at least one first electrical connection member, the base comprising:

[0016] a bearing surface extending in a determined plane and configured to be in contact with the wall;

[0017] a first fixing device, which is configured to allow the threaded element to be fixed by screwing without tools;

[0018] - a first opening configured to allow passage of a first electrical wire and a second electrical connection; and

[0019] - a first housing receiving at least one first electrical connector configured to couple the first electrical wire to a second electrical wire of the electrical cable of the lighting fixture;

[0020] - a partition structure configured to adjust the length of the cable by winding the cable around a second receiving portion in the partition structure, the second receiving portion guiding the wires in a normal direction of the plane; and

[0021] - a first contact surface arranged relative to the second contact surface of the cover to hold the cable in position relative to the supporting means by deformation and compression.

[0022] This support device thus allows to achieve a convenient fixing of the luminaire to the wall and a convenient electrical connection of the luminaire to the electrical device. In fact, thanks to the combination of these technical means, the installer has a tool that allows to prepare the installation of the luminaire without facing the wall, thus adjusting the length of the cables of the luminaire and preparing the electrical connections before installing the luminaire, without having to use tools on the wall.

[0023] According to one variant of the supporting device, the separating structure is configured to allow the superposition of at least two layers of cables.

[0024] Advantageously, the separation structure is configured to ensure at least three turns of the cable.

[0025] Adjustment of the length of the cable leaving the support means may be adjusted by continuously winding the cable in the partition structure.

[0026] According to another variant of the supporting device, the separating structure is provided with protrusions configured to hold the cable in the wound position.

[0027] Thus, when the support device is manipulated or adjustments are made to the ceiling, the adjustment of the length of the cable is still maintained, so that the cable is kept in the desired adjustment position.

[0028] According to a variant embodiment, the threaded element is a screw having a hexagonal or square head blocked in rotation in a cavity of the base, the shape of which is complementary to that of the screw head.

[0029] The installer can screw the support into place without the use of tools simply by rotating the base with his hands.

[0030] According to another variant, the support device comprises second fixing means comprising at least two openings in the base, the at least two openings being configured to fix the support device on the wall by screwing.

[0031] The second fixing means allow the support device to be mounted by means of screws coupled to the insert box or by means of screws screwed into the wall directly or through an expansion sleeve.

[0032] Advantageously, at least two openings are each formed by a groove of a determined width communicating with at least one circular hole having a diameter greater than the width, the diameter ensuring that a screw head already present in the wall passes through the circular hole and is screwed in the groove below the screw head.

[0033] The recess allows mounting on recessed boxes of different diameters, which have different fixing axis spacings and in the case of fixing by means of screws fixed directly in the wall, the installer is no longer forced to place the screws with high precision.

[0034] According to another variant of the supporting device, the first and second contact surfaces together form a bend.

[0035] The bend allows the cable of the lamp to be held in place without squeezing or deforming it. Thus, when a pulling force is transmitted to the cable, the cable is still held in place by the support device comprising the bend.

[0036] According to another variant embodiment, the base is provided with protrusions on the outer surface capable of holding in place a rosace covering the base.

[0037] The aesthetic finish of the support device is achieved by the rosette which is therefore easy to install, being easily put in place and positively retained by the base.

[0038] According to an additional variant embodiment, the base is provided with at least one storage space configured to receive a mounting element that is not used during a mounting operation.

[0039] The installer can thus store unused mounting elements and find them again when disassembling the support device.

[0040] According to a second aspect, the utility model relates to a lamp, comprising a supporting device according to the first aspect of the utility model, such as described above.

[0041] According to a third aspect, the invention relates to a kit or assembly comprising a lamp and a support device according to the first aspect of the invention, such as described above.

[0042] Through various structural and functional aspects such as those described above, the present invention provides installers with a simple and practical tool that allows fast and easy fixing of lamps in different installation situations. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The following will refer to Figures 1 to 14An example of a lamp support device and a lamp comprising such a support device is described, the support device being used for mounting on a wall provided with a power supply.

[0059] Throughout the following description, the same elements are identified with the same reference numerals.

[0060] According to a specific and non-limiting embodiment of the present invention, a support device 100 for a lamp mounted on a wall provided with a power supply comprises a base 10 , a cover 20 mounted on the base, and at least one first electrical connection member 30 .

[0061] According to this example and Figure 1 As shown, the base 10 and the cover 20 are, for example, parts made of a thermoplastic material of the PC (polycarbonate), PP (polypropylene), ABS (acrylonitrile butadiene styrene), PLA (polylactic acid), PETG (polyethylene terephthalate) or PA (polyamide) type, and their shapes are obtained by injection molding or additive printing, such as FDM ("Fused Deposition Modeling" in English and "modelage par en fusion”), SLS (Selective Laser Sintering in English and Frittage Sélectif par Laser in French), SLA (stereolithography) or MJF (Multi-Jet Fusion).

[0062] Of course, it is understood by those skilled in the art that such a component can also be obtained by other manufacturing processes, such as molding by compressing a thermosetting material.

[0063] The installer wishes to install the luminaire 200 on a specific wall with the aid of the support device 100, which is described in the above text according to three installation situations. It should be noted that in the first installation situation, the wall receiving the luminaire 200 to be installed does not have any fixing or electrical connection means, only the cable 320 or wire 321 extending from the wall.

[0064] In a second installation situation, the wall is equipped with an electrical recessed box in which the cables 320 or wires 321 are located.

[0065] In the third installation situation, the wall is therefore a cover 300 or on a lamp connection device (DCL) provided with a standardized connection piece, into which only a second connection piece 310 compatible with the installation connection piece has to be inserted.

[0066] According to this example and Fig. 9 As shown, the installer has a combinable "pendant" consisting of a cable 220 connected to a lamp holder 230, such as Fig.10As shown, the lamp holder 230 can additionally support the lamp cover 250 .

[0067] The lamp holder 230 allows the connection of a standard bulb 240, such as an E27 or E14 screw-in bulb, a B22 bayonet bulb or a GU10, S14d or G9 bulb. These bulbs can be, for example, filament bulbs, halogen bulbs or LEDs ("light emitting diode" in English or "diodeélectroluminescente" in French). When selecting the cross-section of the second wires 221 constituting the cable 220, their energy consumption is particularly taken into account. Therefore, the cross-section of these second wires 221 is, for example, 0.5, 0.75, 1.0 or 1.5 mm 2 .

[0068] The lampshade 250 itself is decorative and can be given different looks, different shapes and different materials. The mass of the support device 100 is taken into account when determining the size thereof so as to support the total mass suspended via the cable 220 .

[0069] According to another example of a luminaire 200 , the cable 220 is connected to a complete luminaire, which is provided, for example, with a light source such as an integrated LED and / or an electronic circuit for converting and / or controlling lighting.

[0070] The installer also has a rosette 210, which is an aesthetic component made of various materials such as plastic or metal, for example, which can be bare, coated or painted. Depending on the style of the luminaire 200, the rosette is given different shapes, such as Figure 1 As shown, its shape is relatively simple; Fig.11 As shown, it has gemstone faces; or Fig.12 and 13 According to these examples, the lamp 200 includes a single pendant, but it may also include multiple pendants, such as Fig.14 shown.

[0071] According to another example of the lamp 200, it is further provided with an additional component constituting a rigid sleeve 260, such as Figure 8 As shown, this rigid sleeve 260 allows the luminaire 200 to be mounted against a wall without the pendant coming into contact with the wall. This rigid sleeve is for example integrally fixed to the base 10 or the cover 20, or even forms part of one of these two parts.

[0072] First, the installer determines the installation height of the luminaire 200 and then determines the length of the cable 220 of the luminaire 200. This length is determined relative to the position of the rosette 210, through which the cable 220 passes through the rosette 210 through the hole 211. In order to indicate the final length of the cable 220 leaving the rosette 210, the installer places a mark on the cable 220. Such a mark is, for example, an additional part that is clipped onto the cable 220 of the luminaire. The mark is placed on the inside of the rosette 210, thus allowing the rosette 210 to slide freely on the cable 220 to abut against the lamp holder 230, for example, when the luminaire 200 is mounted on a wall.

[0073] The installer holds the cover 20 and passes the free end of the lamp cable 220 through the hole 22 provided for this purpose in the cover 20. He then picks up the base 10, faces the cable 220 to the second receiving portion 15 extending from the base 10, inserts the cable into the second receiving portion and then winds the cable 220 in the partition structure 14a of the base 10, as shown in FIG. Figure 6 As shown. Here, the term "winding" is broad. In fact, winding is not only to arrange the cable 220 along a circle or a regular spiral. Winding means winding the cable 220 in the partition structure 14a according to a predetermined path in different path parts located in the partition structure 14a without a specific rule. The winding direction can be changed according to a certain path, and according to another example, the path can include a path part that does not describe a circle or a spiral. In addition, according to different specific embodiments, the determined path is included in a plane or space.

[0074] To this end, the base 10 includes a partition structure 14a, which is configured to adjust the length of the cable 220 by winding the cable 220 around the second receiving portion 15 in the partition structure 14a. Therefore, the cable 220 extends from the second receiving portion 15 to the first receiving portion 13 along a path passing through the partition structure 14a, and the first receiving portion 13 is configured to receive at least one connector 30.

[0075] Figures 1 to 6A partitioning structure 14a according to a particular embodiment is shown. In practice, the partitioning structure 14a shown comprises ribs 14c extending perpendicularly to a plane P defined by a bearing surface 11 in contact with a wall of the receiving support 100. The ribs 14c are arranged circumferentially around the second housing 15 and along at least one axis A2 through which the second housing 15 passes or through the housing 15 and parallel to the plane P, so as to define gaps 14d between the ribs 14c. In the case where the base 10 comprises a circular profile, the second housing 15 is, for example, placed at the center of the circular profile of the base 10 and the axis A2 through which the second housing 15 passes is therefore a radial axis of the circular profile of the base 10. Each gap 14d forms a portion of a path, and the partitioning structure 14a is thus able to receive and guide the cable 220 through a set of path portions forming a determined path in order to adjust the length of the cable 220 by winding the cable 220 in the partitioning structure 14a. Note that the paths are different for inserting wires 220 of different lengths, and that multiple paths allow the same length of cable to be adjusted, depending on the configuration of the ribs 14c. Thus, the cable 220 passes through the partition structure 14a along a determined path, from the second accommodation portion 15 to the first accommodation portion 13, which is configured to receive at least one connector 30. The cable 220 is guided and retained, in particular, along at least a portion of the path between the ribs 14c, i.e., in the gaps 14d.

[0076] In this example, the partition structure 14a is made with the aid of hollow ribs 14c that guide the cable 220. The ribs 14c are arranged in the shape of concentric circular arcs, the center of which coincides with the center of the second housing 15. According to a particular embodiment, the distance between the ribs 14c, i.e. the width of the gap 14d separating the ribs 14c, is determined to allow the cable 220 to pass freely, thus avoiding any effort by the installer in arranging the cable 220 in the partition structure 14a. According to another particular implementation variant, the spacing between two ribs 14c, i.e. the width of the passage in the gap 14d, is smaller than the outer diameter of the cable 220, for example a few tenths of a millimeter (mm) smaller, so as to keep the cable 220 in place in the gap 14d without requiring significant effort by the user to insert the cable 220 into the partition structure 14a.

[0077] In this example, in order to give a large adjustment range of the length of the cable 220, the partition structure 14a is constructed to allow at least two layers of cables 220 to be stacked. Therefore, each gap 14d is constructed to allow at least two layers of cables 220 to be stacked. Then, the partition structure 14a makes it possible to propose multiple paths, which include path portions that are located in a plane parallel to the plane P and are spaced apart in pairs at a height defined by the outer diameter of the cable 220. In this way, the amplitude of the adjustment range is doubled or even tripled. Therefore, if 30cm of cable 220 can be wound per layer per turn in the partition structure 14a, now about 60cm or even 90cm of cable can be wound per turn in the partition structure 14a in a superimposed manner. For example, the cable 220 is arranged along a path that passes through the same gap 14d multiple times but passes through or does not pass through all the gaps 14d. Therefore, the path along which the cable 220 passes through the partition structure 14a is defined in three dimensions, and the multiple possible selections of the path portions allow the length of the cable 220 to be adjusted in large and fine amplitudes at the same time.

[0078] In this example, the partition structure is also configured to ensure that the cable 220 is wound at least three times, so that if one turn represents 12 cm of cable, three turns represent an adjustment of about 40 cm in the length of the cable 220. Therefore, the arrangement and thickness of the ribs 14c allow a large volume of cable 220 to be arranged in the partition structure 14a, in other words, a large storage capacity for the cable 220 is obtained due to the density gain of the cable 220 or the volume gain occupied by the cable 220. Thus, for a cable with a diameter of 10 cm and a rib thickness of 3 cm, the cable 220 occupies up to 60% of the volume including the partition structure 14a when guided in the partition structure 14a.

[0079] When the ribs 14c are perforated, it is also possible to perform paths other than simple regular windings, that is, instead of winding along the entire path proposed in the partition structure 14a, the path of the cable 220 in the partition structure 14b is adjusted so as to more precisely adjust the length of the wound cable 220, for example by performing a partial turn. The fact of opening the ribs 14c of the partition structure 14a also allows to increase the occupancy density of the cable 220 by reducing the volume occupied by the ribs 14c in the partition structure 14a.

[0080] According to another embodiment, the support device 100 is provided for connecting a plurality of cables 220, for example 2, 3 or 5 cables 220. Thus, each cable 220 is arranged between the same first housing 13 and the second housing 15 assigned thereto. Then, the base 10 has a plurality of partition structures 14a, which are arranged in such a way that each cable 220 can be wound around the second output housing 15 assigned to the base 10 in its specific partition structure. Of course, it is also possible to manufacture a base 10 provided with a single partition structure 14a, which is arranged so that each second housing 15 assigned to a cable 220 is located inside the partition structure 14a. Thus, different cables 220 pass through the same partition structure 14a that they share, using different paths in order to adjust each cable 220 to the desired length.

[0081] In this example and if Figure 6 As shown, the partition structure 14a is provided with a protrusion 14b, which is configured to keep the cable 220 in the wound position. For example, the protrusion 14b is positioned at the top of the rib 14c. The protrusion 14b is therefore arranged at the entrance of each gap 14d formed by the partition structure 14a. At the entrance of the gap 14d, the cross-section of the channel is therefore reduced to be smaller than the diameter of the cable 220. Therefore, when the cable 220 is inserted into the gap 14d, the installer forces the cable 220 to pass behind the protrusion 14b, and the rib 14c is therefore deformed to allow the cable 220 to pass and then return to its static position, thereby fixing the cable 220 in a suitable position in the gap 14d formed by the rib 14c of the partition structure 14a.

[0082] Also according to this example, the rib 14c is provided with fillets 14e at its base. These fillets 14e allow the rib 14c to be reinforced and prevent its base from breaking when inserting the cable 220. The fillets 14e of the same gap 14d, i.e. the fillets 14e facing each other, form grooves 14f in pairs, which can guide the cable 220 in the gap 14d.

[0083] Since this operation of adjusting the length of the cable 220 is performed before mounting the support device 100 to the wall, the installer can easily adjust the length of the cable 3 without being in an uncomfortable position, such as when the wall is a ceiling. The installer does not have to work with his arms raised in the air, but can instead work while sitting and placing the support device 100 on a table.

[0084] Once the cable 220 is positioned, the installer strips it so that the second wire 221 constituting the cable 220 is exposed. He also strips the ends of the wire 221 to arrange the exposed conductor so that it is placed in the terminal of the connector 30, which is configured to connect the installed first wire 321 to the second wire 221.

[0085] The first electric wire 321 and the second electric wire 221 are flexible, rigid or multi-stranded wire types. The first electric wire 321 is connected to the second electric wire 221 through a screw, automatic or lever type connection member 30.

[0086] In this example and if Figure 5 As shown, three connectors 30 are arranged in the first housing 13 for receiving them. These connectors 30 are detachable so that electrical connection can be easily made, and once the cover 20 is in place, the connectors are held in place. The number of the three connectors here is related to the number of phases to be connected, and the number is 3 to connect the phase line, neutral line and ground line corresponding to the connection of the Class 1 electrical lamp 200 that needs to be grounded. For example, if the lamp 200 is Class 2, that is, it does not require grounding or equipotential bonding because it is provided with double electrical insulation, the number of connectors can be 2. Likewise, the connectors 30 are not always connected to the electrical wires, so there can be 3 connectors 30 but only 2 phases: one phase line and one neutral line.

[0087] According to this example, the connector 30 used is of the lever type. This connector is compatible with all the wire types described above. The installer has at his disposal a lever which allows the conductor of the wire to be freely inserted into the terminal when the lever is in the open position and which allows the conductor of the wire present in the terminal to be released in the event of removal. In the closed position, on the contrary, the lever releases a spring which clamps the conductor of the wire, thereby keeping it in place and establishing an electrical contact between the terminal of the connector 30 and the conductor of the wire. The connector 30 is provided with a determined number of phase inputs, for example 2 inputs if it is to be concerned with connecting a single first wire 321 of the same phase to a single second wire 221 of the same phase; or with a plurality of inputs in the case of splicing, that is to say in the case where a plurality of first wires 321 are of the same phase and should be connected to one another, or in the case where the luminaire is provided with a plurality of cables 220 associated with a plurality of pendants, for example Fig.14 3 pendants shown.

[0088] In the case of installation on the DCL, the installer also connects each first wire 321 of the cable 320 connected to the plug DCL 310 to the connector 30 .

[0089] Then, the installer positions each connector 30 in the first housing 13 provided therefor. In order to keep the cable 220 and each connector 30 in place, the installer slides the cover 20 along the cable 220 and then faces the base 10, with the second housing 15 facing the hole 22.

[0090] In this example and if Figure 4As shown, the cover 20 is partially inserted into the base 10 by vertical translation, the vertical axis A being defined as the normal to the support plane P coinciding with the support surface 11 of the base 10, the support surface 11 being the surface in contact with the wall once the support device 100 is mounted and passing through the center of the second housing 15, as shown in FIG. Figure 2 As soon as the cover 20 is in abutment in the base 10, i.e. as soon as the lower face 21 of the cover 20 comes into contact with the face defining the bottom of the second housing 15, the installer pivots the cover 20 by a quarter of a turn about the vertical axis A, the fins 23 thus inserting into the complementary shape realized in the base 10. In order to facilitate the locking of the cover 20 in the base 10 by rotation, the installer has a clamping area 24 that facilitates the operation. In order to block the cover 20 in a defined position, a lug 25 is placed on one of the faces of the cover 20, the lug 25 inserting into a complementary housing 102 provided in the base 10. The installer is thus informed of the good positioning of the cover 20 on the base 10 when he feels, by force feedback, that the lug 25 has reached its housing 102.

[0091] Other ways (not shown here) of assembling the cover 20 to the base 10 are also conceivable, such as clamping the cover 20 to the base 10 or assembling by screwing. Therefore, the installer only needs to apply simple pressure to firmly fix the cover 20 to the base 10 or only needs to tighten at least one screw.

[0092] In this example, the positioning of the cover 20 on the base 10 allows obtaining a 2-level subassembly, in fact, the conductive parts of the assembly are protected by:

[0093] - cables 320 and 220 having two insulating jackets which constitute the outer sheath of the cable and the sheath of each wire 321 , 221 ,

[0094] - a sheath for each wire 321, 322 and a housing comprising the cover 20 and the base 10, and / or

[0095] A connection 30 housed under the housing comprising the cover 20 and the base 10 .

[0096] Furthermore, in this example, the supporting device 100 includes three first electrical connectors 30 , one of which is used to ground the lamp 200 , so the supporting device 100 is compatible with any Class 1 or Class 2 lamp 200 .

[0097] In the same example, once the cover 20 is mounted on the base 10, the cable 220 of the lamp is locked, and the first contact surface 16 of the base 10 arranged relative to the second contact surface 21 of the cover 20 holds the cable 220 in place relative to the support device 100 by deformation and compression.

[0098] The first contact surface 16 is implemented in the shape of a rib, which is placed in the partition structure 14a on the path of the cable 220. The rib is placed at the entrance of the second receiving portion 15, and the cable 220 always passes through the entrance.

[0099] The second contact surface 21 coincides with the lower surface of the cover 20 .

[0100] According to this example and Figure 3 As shown, the first contact surface 16 and the second contact surface 21 are offset, and the first support point between the support surface 16 and the cable 220 and the second support point between the support surface 21 and the cable 220 are located on the same plane normal to the plane P and passing through the vertical axis A, and the distances to the vertical axis A are different. The first contact surface 16 and the second contact surface 21 together form a bend. The first and second support points are separated by a distance greater than the diameter of the cable 220, thereby forcing the wire 220 to deform along the path formed by the bend but not cut. Therefore, the integrity of the cable 220 is maintained, but the cable 220 is retained by the assembly formed by the assembled base 10 and the cover 20.

[0101] When the cover 20 is mounted on the base 10, the installer pushes the cover 20 towards the base 10, thereby pressing the cable and deforming the cable 220. Once the cover 20 is in place, the fins 23 of the cover 20 positioned in the complementary grooves of the base 10 remain pressed. Therefore, the mechanical strength of the cable 220 in the face of traction is ensured by the deformation of the cable 220 passing through the bend thus achieved.

[0102] In order to fix the assembly thus constituted by the installer to the wall, the installer needs to remove the fixing hook if there is no DLC. The installer thus positions the assembly in a housing provided for this purpose on the base 10, which housing is provided with at least one storage space configured to receive mounting elements not used during the installation operation in order to avoid losing some of these elements. For example, there may be a free volume between the base 10 and the rosette 210, and a retaining device such as a clip is provided on the base 10 to receive the fixing hook of the DLC. Thus, at the stage of replacing the support device 100, the installer easily finds the fixing hook.

[0103] According to this example and Figure 3 As shown, in order to fix the support device 100 to the cover 300 of the DCL, the base 10 includes a first fixing device, which is configured to allow fixing without tools by screwing the threaded element 40. The installer first inserts the threaded element 40 into the base 10 before setting the cable 220 and installing the cover 20. In fact, once the cable 220 and the cover 20 are set in place, the housing 17 receiving the threaded element is closed.

[0104] The diameter and pitch of the threaded element 40 are similar to those of the pre-disassembled DCL hook. These dimensions are common when mounted on a DCL, and such hooks are typically used to match the standard insert boxes described above. Therefore, such dimensions of the threaded element provide it with sufficient resistance to pulling forces, and the pulling forces applied are similar to those applied to the hook.

[0105] In this example, the threaded element 40 is a screw with a hexagonal head, the rotation of which is blocked in a cavity 17 of the base 10, the shape of which is complementary to the shape of the head of the screw. It should be noted that a square head shape is also suitable, and therefore the cavity 17 has a suitable square shape.

[0106] This embodiment is not the only possibility, and those skilled in the art may also propose other solutions, such as making the threaded element 40 directly on the body of the base 10, or directly molding or printing the base 10 on the threaded element 40, so that the threaded element 40 is embedded in the base 10. In these specific embodiments of the first fixing device, the advantage of the first embodiment is that the threaded element 40 is allowed to be separated, so that the threaded element 40 is removable and inconspicuous when the support device 100 is installed without using these threaded elements.

[0107] According to this example, the base 10 is mounted on the wall without the use of tools; it is sufficient for the installer to turn the base 10 by hand so that the support surface 11 comes into contact with the wall by screwing the threaded element 40, which is then screwed into a part of the embedded box provided for this purpose or into an expansion sleeve previously provided in the wall.

[0108] The screwing is very simple by simply rotating the base 10 by hand without tools. In fact, the width or outer diameter of the base 10 is significantly greater than the width or diameter of the screwdriver handle. The width or diameter of the base 10 is, for example, 70, 90, 120, 150 mm. Therefore, the torque obtained by the user rotating the base 10 is very large compared to the torque of the couple obtained by means of a screwdriver or a tool with a size close to the size of the screwdriver handle. Therefore, the installer comfortably fixes the base 10 to the wall.

[0109] The large torque generated by the rotation of the base 10 during the operation of screwing the threaded element 40 and the pressure exerted by the threaded element 40 along its rotation axis are transmitted to the area where the base 10 is in contact with the threaded element 40. Therefore, according to a specific embodiment, ribs are made in the base 10 around the cavity 17 to reinforce this part of the base 10 and make it more solid.

[0110] When the support surface 11 contacts the cover 310 of the DCL and the first opening 12 of the base 10 faces the DCL connector, the rotation of the base 10 is completed, and the first opening 12 is configured to allow the first wire 321 and the second electrical connector 310 to pass through. Therefore, the installer can insert the second electrical connector 310, here the plug DCL, through the first opening 12.

[0111] The base can, for example, be deformed with the surface of the wall to adapt to the shape of the wall and to accept imperfections in planarity.

[0112] According to another example not shown, the base includes an elastic component on its back, such as a coupling made of rubber, silicone or polyurethane elastomeric material. The elastic component can be deformed to, for example, fill the surface of the wall with a few millimeters of concave and convex, such as 1,2 or 3mm, so as to provide sealing at the joint between the base 10 and the wall. According to a first specific embodiment of the elastic component, the elastic component is inseparable from the base 10. The elastic component is, for example, manufactured by overmolding, that is, directly injecting a second material on the main body of the base 10 for molding, so that the main body of the base 10 and the elastic component are integrated. According to a second specific embodiment of the elastic component, the elastic component is configured as another component separated from the base 10. The elastic component is therefore a coupling, which is, for example, annular and accommodated in a groove in the support surface 11 implemented in the base 10. This annular coupling is, for example, a coupling existing on the market, which helps its supply and allows to be conducive to a wider selection of size, shape and material to meet different needs, which are determined according to the type of wall and the environment in which the support device 100 including the coupling is placed.

[0113] According to this example and Figure 6 As shown, the base 10 is provided with a protrusion 19 on the outer surface, which is able to keep in place a rosette 210 covering the base 10. This rosette 210 has a decorative function, which allows hiding the base 10, the cover 20, the different fixing means, at least one connection 30 and the cables 320 and 220. The rosette 210 is kept in place by the base 10. The rosette has no mechanical effect, since the base 10 is fixed to the wall and the other elements of the support device 100 are fixed to the base 10, so that it is not necessary to make a very strong assembly device. The rosette 210 is, for example, pressed on the base 10, so as to abut against the protrusion 19, or is clipped on the base 10.

[0114] In the case where the installation does not include a DCL, the installation of the support device 100 on the wall is different.

[0115] In this example and if Figure 6As shown, the support device 100 comprises a second fixing means. The base 10 comprises two openings 18, which are configured to fix the support 10 on the wall by screwing. The two openings 18 are configured to allow the body of the fixing screw to pass through and be tightened under the screw head. Therefore, in the absence of a dedicated fixing on or in the wall, the installer fixes the support device 100 on the wall according to traditional fixing methods. Therefore, it is sufficient for the installer to, for example, open an orifice in the wall, insert an expansion sleeve adapted to the wall type and then fix the base 10 of the support device 100 by screwing the screws through the openings 18.

[0116] According to this example, the two openings are each formed by a groove 18a of a certain width, which communicates with at least one circular hole 18b of a diameter greater than the width of the groove, thereby ensuring that the screw head passes through the circular hole 18b and is tightened in the groove 18a under the screw head. Such an opening 18 is generally called a grommet. It allows the installer to fix the support device 100 to the wall without completely removing the existing screws on or in the wall.

[0117] For example, if the wall is provided with an embedded box including two fixing screws arranged at an axial spacing of 47, 60 or 71 mm, the installer first partially unscrews the screws so that they protrude from the wall, the distance separating the wall from the bottom of the screw head is greater than the thickness of the base 10 around the groove 18a. Therefore, the installer passes the first screw head through the circular hole 18b, and then translates the base 10 so that the second circular hole 18b faces the head of the second fixing screw. Once all the fixing screws have passed through the opening 18, the installer translates the base 10 so that each fixing screw head faces the groove 18a, and then tightens the screws to hold the base 10 in place on the wall.

[0118] Once the base is fixed to the wall, the installer puts away the power supply. It is in the form of cables 320 or wires 321. The installer grabs these cables or wires and passes them through the first opening 12, which is made to allow the support device 100 to be used simultaneously for power supplies including directly accessible wires or cables, extending from the wall or arranged in an embedded box present in the wall. Therefore, the shape of the first opening 12 is defined to allow multiple wires 321 that are free or arranged in the cable 320 to pass through. For easier installation, the shape of the first opening 12 is wider than necessary, thereby providing clearance and positioning freedom for the base 10. If necessary, the installer can strip the cables 320 and wires 321 and connect them to each first electrical connector 30.

[0119] It is noted here that the first connection element 30 may be adapted to be relocated in case there are multiple cables 320 or multiple wires 321 of the same phase. Thus, the support device 100 integrates a connection element with multiple inputs for each phase.

[0120] It should also be noted that in order to obtain a Class 2 assembly and in the case where the installation has wires 321 instead of cables 320, the installer adds a jacket on each wire 321 to obtain double insulation of the conductors.

[0121] Then, the installer places the cover 20 on the base 10, thus holding each element in place. Then, the installer slides the rosette along the cable 220 until the rosette covers the support device 100.

[0122] The installer thus has a practical tool that is suitable for every installation situation. This versatile solution allows him to easily install different luminaires with greater convenience.
