    [0001] TECHNICAL FIELD TO WHICH THE INVENTION RELATES The present invention relates generally to the embedding in the hollow walls of electrical equipment. It relates more particularly to a mounting frame for embedding an electrical box in a wall. It also relates to an assembly comprising such a mounting frame and an electrical box.
    [0002] TECHNICAL BACKGROUND Generally, to embed any electrical equipment in a hollow wall, an electrical installer uses an electrical box that it inserts inside a recess hole drilled in said wall. Conventionally, this electrical box comprises, around its front opening, a collar and retaining tongues which, when the diameter of the mounting hole is adapted to that of the electrical box, rest on the front face of the wall in order to hold back said electrical box, the retention towards the front of said electrical box in the mounting hole being ensured, for example, by means of claw screws provided on the periphery of the electrical box whose claws cling against the rear face of the wall when screwing said claw screws. When the diameter of the recessed hole is substantially greater than that of the electrical box, for example if the installer was mistaken during the drilling of said hole, or if the hole was previously provided to accommodate an older electrical box larger , the flange and the retaining tabs of the electrical box are found weakly, if at all, in support on the front face of the mounting wall, so that the mechanical strength of the electrical box in the wall is compromised or absent . OBJECT OF THE INVENTION In order to overcome the above-mentioned drawback, the present invention proposes an intermediate mounting frame between the electrical box and the hole in the recess wall making it possible to adapt the diameter of the electrical box to the diameter, more large, recess hole. More particularly, there is provided according to the invention a mounting frame for embedding an electrical box, comprising an inner edge which defines a central opening for receiving said electrical box, an outer edge from which at least one flange d 'Support extends outwardly of said mounting frame, fixing tabs comprising, on an outer face facing outwardly of the mounting frame, means for anchoring in a mounting wall, said mounting tabs being articulated on the mounting frame. Each bracket of this mounting frame comprises on an inner face, opposite to said outer face, a ramp adapted to cooperate with an element attached to said electrical box to deploy said bracket from a retracted position. Thanks to the mounting frame according to the invention, it is therefore easy to fix the electrical box in a hole of a mounting wall whose diameter is greater than that of the electrical box. The mounting frame according to the invention thus makes it possible to adapt the diameter of the electrical box to that of the hole and to fix it simply and quickly in this hole. Indeed, thanks to the ramps located on the inner faces of the hinged mounting brackets of the mounting frame, these brackets will be able to deviate to allow both the anchoring of the mounting frame in the hole of the wall mounting and fixing the electrical box on the mounting frame. Other nonlimiting and advantageous features of the mounting frame according to the invention are the following: each fixing lug has dimensions adapted so that, during insertion of said electrical box through said central opening of the frame mounting, each bracket is capable of being inserted into a recess of the outer surface of the side wall of said electrical box, with its inner face provided with said ramp facing the bottom of said recess; said inner face of each fixing lug has a curved profile with two inclined faces which extend from the ends of said fixing lug to join continuously a top, the inclined flange extending from the free end of the lug of fastener forming said ramp; the outer face of each fixing lug comprises teeth; the outer face of each fixing lug comprises parallel serrated ribs; said fixing lugs come to form with said mounting frame, and the hinge means of each fixing lug comprise a hinge film; - there is provided a single support flange running all the way around the central opening; and a plurality of support flanges distributed around the periphery of the central opening are provided.
    [0003] The invention also proposes an assembly comprising a mounting frame according to the invention and an electrical box comprising a side wall flanked by a flange, said electrical box being engaged through the central opening of the mounting frame so as to that its collar rests at least partially on each support flange of the mounting frame.
    [0004] Advantageously, the outer surface of the side wall of the electrical box comprises recesses which extend over the height of said side wall and which house claw screws, each mounting bracket of the mounting frame being placed in the retracted position. in a recess, with its internal face turned towards the bottom of said recess so that the claw of the claw screw housed in said recess is adapted to bear on said ramp of the fixing lug, during its ascent along the claw screw for pulling said fixing lug of said recess in the deployed position.

In the preamble, it will be noted that the identical or similar elements of the different embodiments of the invention shown in the different figures will, as far as possible, be referenced by the same reference signs and will not be described each time. Furthermore, in the following description, the terms "front" and "back" will be used with respect to the direction of a user's gaze facing the recess wall and will respectively denote the outward facing location. of this wall and the place turned towards the interior of this wall. In Figures 1 to 17, there are shown two embodiments of a mounting frame 100; 200 and an assembly incorporating such a frame and an electrical box 20. The electrical box 20 serves to embed an electrical equipment in a wall 10.
    [0005] Indeed, conventionally, to embed any electrical equipment (not shown) in a wall 10, it is appropriate to make a hole 13 in this wall and to mount in this hole 13 an electrical box 20 for receiving the mechanism of the electrical equipment as well as the electrical conductors coming from the electrical network for serving this mechanism.
    [0006] According to the example shown in Figure 1, the hole 13 is a circular opening which has an axis of revolution Al and a diameter Dl. As shown more particularly in FIGS. 5, 6 and 17, the electrical box 20 here conventionally has a cylindrical shape of revolution of circular section, with a side wall 21, a bottom 22 and, opposite the bottom 22, an opening front 23 through which is introduced the mechanism of the apparatus in the electrical box 20. The side wall 21 of the electrical box 20 carries outside a collar 23A which runs along the front opening 23 of the electrical box 20. This flange 23A has four retaining tongues 23B which extend outwardly in two perpendicular directions. The flange 23A provided with its retaining tabs 23B is intended to bear on the front face 11 of the wall 10 to retain back the electrical box 20 placed in the hole 13 of said wall 10. In addition, the restraint to the front of the electrical box 20 placed in the hole 13 of the wall 10, is provided by a system of claws 25. As shown more particularly in Figures 5 and 6, the outer surface 21 B of the side wall 21 of the electrical box 20 has two recesses 24 which house screws 26 claw. Conventionally, each screw 26 of claw is engaged in its recess 24 through a threaded well 27 which opens at the front opening 23, on the flange 23A of the electrical box 20. Each claw screw 26 cooperates with a claw 25 and is held fixed in translation in its recess 24 so that when screwing the claw screw 26 in the threaded well 27, the claw 25 rises along the threaded body of the claw screw 26 from a low position in which claw 25 retracted into the recess 24 of the electrical box 20. There is provided in the bottom 24B of each recess 24, an inclined plane against which each claw 25 is supported during its ascent along the threaded body the claw screw 26 to exit the recess 24 and to take a high position protruding from the outer surface 21B of the side wall 21 of the electrical box 20. In this high position, each claw 25 is capable of endre pressing against the rear face 12 of the wall 10 in order to retain forward the electrical box 20 placed in the hole 13. Advantageously, and it is the object of the present invention, here, to mount the electrical box 20 inside the hole 13 of the recess wall 10, the mounting frame 100 is used; 200 which will be interposed between the wall 10 and the electrical box 20. As shown more particularly in Figures 2 to 4, 16, 17, this mounting frame 100; 200 is defined between an outer edge 102 and an inner edge 101 which delimits a central opening 103 intended to receive the electrical box 20.
    [0007] The shape of the outer edge 102 of the mounting frame 100; 200 is advantageously adapted to the contour of the hole 13 of the wall 10 of embedding, while the shape of the inner edge 101 of the mounting frame 100; 200 is adapted to the outer shape of the electrical box 20. The mounting frame 100; 200 is here in the form of a circular ring with a cylindrical wall of revolution about a central axis A2, whose inner face forms the inner edge 101 and whose outer face forms the outer edge 102 of the mounting frame 100; 200. The electrical box 20 is intended to be engaged through this circular ring. However, alternatively, it could be provided that the mounting frame has oblong, square or rectangular external and internal contours so as to adapt to the contour of the mounting hole and to receive an oblong, square or rectangular electrical box. The cylindrical wall of the mounting frame 100; 200 has along the central axis A2 a height H (see Figure 4) adapted to the thickness of the wall 10. This cylindrical wall further has a thin thickness. The internal diameter D2 of the cylindrical wall of the mounting frame 100; 200, equal to the diameter of the central opening 103, corresponds to the clearance close to the outer diameter of the side wall 21 of the electrical box 20. According to a first embodiment shown in FIGS. 2 to 4, the mounting frame 100 comprises a single support flange 104 extending from the outer edge 102 outwardly of the mounting frame 100. This bearing flange 104 runs continuously along the periphery of the central opening 103 of the mounting frame It runs along the front edge of the cylindrical wall of this frame. It has the shape of a flat ring of axis of revolution A2, with a front face 104A and an opposite rear face 104B. According to a second embodiment shown in FIGS. 16 and 17, the mounting frame 200 comprises a plurality of support flanges 204 which extend from the outer edge 102 outwardly of the mounting frame 200. here four disjointed support flanges 204 distributed regularly around the periphery of the central opening 103 of the mounting frame 200. Each bearing flange 204 extends in length over an angular sector portion along the front edge of the cylindrical wall of the mounting frame 200. It has the shape of a flat ring portion with a front face and an opposite rear face. The four support flanges 204 are inscribed in a single ring which surrounds the cylindrical wall of the mounting frame 200. The dimensions of each support flange 104; 204 of the mounting frame 100; 200, that is to say the outer diameter D3 of the bearing flange 104 (see Figure 4) and the width L of the support flanges 104; 204 (see Figure 2), are such that: - on one side, the rear face 104B of each support flange 104; 204 is able to rest against the front face 11 of the wall 10 when the mounting frame 100; 200 is inserted into the hole 13 of the wall 10 (see Figure 14B), and - on the other side, the front face 104A of each support flange 104; 204 serves as a bearing surface for the retaining tabs 23B of the flange 23A of the electrical box 20 when this box is engaged through the mounting frame 100; 200 (see Figure 12). The mounting frame 100; 200 is preferably made of plastic, but alternatively it could be envisaged that it is made of metal material. In order to stiffen the mounting frame 100, it has on its outer edge 102, reinforcing brackets 102A regularly spaced around its periphery and connecting the outer edge 102 to the rear face 104B of the support flange 104.
    [0008] Advantageously, as shown in Figures 2 to 6, 16 and 17, the mounting frame 100; 200 comprises fixing lugs, here two fastening lugs 110, 120, which extend outwardly of the mounting frame 100; 200 and which are articulated on the mounting frame 100; 200.
    [0009] Preferably, the fixing lugs 110, 120 are formed with the mounting frame 100; 200 and form with it a single piece molded plastic. Each fixing lug 110, 120 is connected to the rear edge (opposite to the front edge) of the cylindrical wall of the mounting frame 100; 200 by means of a hinge film 113, 123 made during the molding operation. Each hinge film 113, 123 is a thin and flexible plastic film allowing the pivoting of each fastening lug 110, 120 along a pivot axis A3 (see FIGS. 2 and 3). According to a variant not shown, it could be provided that each bracket is attached to the cylindrical wall of the mounting frame, for example by means of latching means snapped onto a hinge axis provided on the cylindrical wall of the mounting frame. The fixing lugs 110, 120 are thus articulated in rotation about the pivot axes A3 between two extreme positions, namely: a retracted extreme position corresponding to a delivery position of the fixing lugs 110, 120 before use of the mounting frame 100; 200 (the case of Figures 2 and 16 for example), and - an extended position when the fixing lugs 110, 120 are completely raised outwardly, then abutting against the rear edge of the cylindrical wall of the mounting frame 100; 200 to which they are attached. Thanks to the elasticity of each hinge film 113, 123, the fastening lugs 110, 120 can take any intermediate position between the retracted end position and the extended end position.
    [0010] It will be considered here that this intermediate position of the fixing lugs 110, 120 is: a retracted position when the fixing lugs 110, 120 are brought closer to each other towards the inside of the mounting frame 100; 200 (see for example Figures 9B and 11B), or an extended position when the brackets 110, 120 are moved away from each other outward of the mounting frame 100; 200 (see FIGS. 10B and 15B). The fixing lugs 110, 120 each comprise an inner face 111, 121 and an opposite outer face 112, 122 (see FIG. 4). The inner face 111, 121 of each fixing lug 110, 120 is the face which faces the inner edge 101 of the mounting frame 100; 200, that is towards the center of the central opening 103 of this frame. The outer face 112, 122 of each fixing lug 110, 120 is, for its part, that is turned towards the outer edge 102 of the mounting frame 100; 200, opposite the center of the central opening 103 of this frame. As shown in FIGS. 3 and 6, the fastening lugs 110, 120 comprise, on their outer face 112, 122 means of anchoring to the wall 10. Here, these anchoring means comprise ribs 114, 124 which are notched at the same time. each of the pointed teeth 114A, 124A intended, when the fixing lugs 110, 120 are in the extended extended position, to be anchored in the rear face 12 of the wall 10 to fix the mounting frame 100; 200 to the wall 10. Each fixing lug 110, 120 further comprises, on its inner face 111, 121, a ramp 115, 125 adapted to cooperate with an element attached to the electrical box 20 inserted through the central opening 103 of the mounting frame 100; 200, to deploy each bracket 110, 120 from a retracted position. Here, preferably, the inner face 111, 121 of each fixing lug 110, 120 has a curved profile with two inclined faces 115, 116, 125, 126 which extend from the ends 110A, 110B, 120A, 120B of each leg 110, 120 to join continuously a top 117, 127 (see Figures 2 to 4). The inclined face 115, 125 extending from the free end 110A of each fixing lug 110, 120 advantageously forms said ramp 115, 125 of each fixing lug 110, 120.
    [0011] Here, as will be described hereinafter, it is the claws 25 of the claw screw systems of the electrical box 20 which are adapted to cooperate with the ramps 115, 125 of the mounting lugs 110, 120 of the mounting frame 100 ; 200. Thus, preferably, as shown more particularly in Figures 11A and 11B, each bracket 110, 120 of the mounting frame 100; 200 has dimensions (width, height and thickness) adapted so that, during the insertion of the electrical box 20 through the central opening 103 of the mounting frame 100; 200, each fixing lug 110, 120 is capable of being inserted in the retracted position in one of the recesses 24 of the outer surface 21B of the side wall 21 of said electrical box 20, with its internal face 111, 121 provided with said ramp 115, 125 turned towards the bottom 24B of said recess 24. In order to clearly understand the advantages of the mounting frame 100 according to the invention which has just been described in detail, the following will now be described, with reference to FIGS. 7A to 15B, the main steps of mounting the electrical box 20 in the hole 13 of the wall 10 using the mounting frame 100. It will first be observed that for the attachment of the electrical box 20 in the hole 13 of the wall 10 , two possibilities are available to the installer.
    [0012] The first possibility is to first mount the mounting frame 100 in the hole 13 of the wall 10, then second engage the electrical box 20 in the central opening 103 of the mounting frame 100. The second possibility is to engage the first box electrical 20 in the central opening 103 of the mounting frame 100 to achieve an assembly that is inserted into the hole 13 of the wall 10. We will describe below this second possibility, the first possibility is easily deduced. As shown in Figures 7A, 7B, 8A and 8B, in a first step, the installer partially engages the electrical box 20 in the central opening 103 of the mounting frame 100 so that the recesses 24 of the electrical box 20 is positioned directly above the fixing lugs 110, 120 of the mounting frame 100 which are in the retracted extreme position. In order to facilitate the positioning of the electrical box 20 with respect to the mounting frame 100, grooves 101A (see FIGS. 2 and 3) which extend parallel to the groove 101A are provided in the inner edge 101 of the mounting frame 100. central axis A2 over the entire height of said cylindrical wall, in which the external faces of threaded wells 28A of the electrical box 20, provided for screwing screws 26, for the attachment of an apparatus support ( not shown) on the electrical box 20. This sliding engagement tapped wells 28A in the grooves 101A, to block the rotation of the electrical box 20 relative to the mounting frame 100 by indexing the position of the recesses 24 relative to the legs 110, 120. From this configuration, the installer fully engages the electrical box 20 through the central opening 103 of the mounting frame 100 by sliding the cylindrical wall ue of the mounting frame 100 along the side wall 21 of the electrical box 20 (see Figures 9A to 11 B). Thanks to the domed profile of the inner face 111, 121 of the fixing lugs 110, 120, in particular thanks to the inclined faces 116, 126, and thanks to the hinge films 113, 123 of the fixing lugs 110, 120, during this sliding when the fixing lugs 110, 120 meet the bottom 22 of the electrical box 20, they retract towards the outside of the mounting frame 100, pushed by said bottom 22 (see FIGS. 9A to 10B). Then, continuing the sliding of the mounting frame 100 on the electrical box 20 until the front face 104A of the support flange 104 of the mounting frame 100 comes to press against the rear face of the flange 23A of the electrical box 20, when the fixing lugs 110,120 exceed the claws 25 of the electrical box 20, thanks to the elasticity of the hinge films 113, 123, they are close to one another and fall back inside the mounting frame 100, in the direction of the central axis A2, each being inserted in the retracted position in a recess 24 of the electrical box 20. The inner face 111, 121 of each bracket 110, 120, which is equipped with the ramp 115, 125, is then turned towards the bottom 24B of the recess 24 so that each ramp 115, 125 is oriented towards a claw 25 of the claw screw system of the electrical box 20 (see FIGS. 11A and 11 B). At the end of this assembly operation of the electrical box 20 with the mounting frame 100 (see FIGS. 11A and 11B), the installer has a set ready to be installed in the hole 13 of the wall 10. note here that the hole 13 has a diameter too large relative to the electrical box 20, so that if the installer was trying to mount the electrical box 20 only in the hole 13, the flange 23A and 23B retaining tabs this electrical box 20 would rest only partially or not at all on the front face 11 of the wall 10, so that the installation of such an electrical box 20 would be compromised, if not impossible.
    [0013] It is an advantage of the mounting frame 100 to allow the mounting of such an electrical box 20 in the wall 10 despite a diameter of electrical box 20 too small compared to that of the hole 13 formed in the wall 10.
    [0014] This may be the case, during a renovation of the electrical installation, when the electrical box 20 replaces an old electrical box of larger diameter, substantially equal to the diameter D of the hole 13. This may be the case also when the installer mistakenly drills a hole 13 of diameter too large compared to that of the electrical box that it wants to embed in the wall. Then, the installer inserts this assembly into the hole 13 of the wall 10 so that the rear face 104B of the mounting frame 100 comes to rest against the front face 11 of the wall 10 (see FIGS. 12 and 13). The support flange 104 of the mounting frame 100 thus allows not only the retention of the mounting frame 100 rearward but also the rearward restraint of the electrical box 20 through the flange 23A which rests on the front face 104A of said support flange 104. However, in the configuration of Figures 12 and 13, the assembly still remains mobile in translation and rotation in the hole 13 of the wall 10.
    [0015] Also, in order to fix, on the one hand, the mounting frame 100 on the wall 10, and, on the other hand, the electrical box 20 on the mounting frame 100, the installer screws the screws 26 of the claw of the electrical box 20 so as to bring out the claws 25 for fixing the electrical box 20 (see FIGS. 14A to 15B), which go up along the threaded bodies of the screws 26.
    [0016] As shown more particularly in FIGS. 15A and 15B, during their ascent, the claws 25 come to bear against the ramps 115, 125 of the fixing lugs 110, 120 of the mounting frame 100, which causes the pivoting towards the outside of said attachment lugs 110, 120 which pass from their retracted intermediate position to an extended intermediate position.
    [0017] More precisely here, thanks to the convex shape of the ramps 115, 125 located on the inner faces 111, 121 of the fixing lugs 110, 120 of the mounting frame 100 and thanks to the elasticity of the hinge films 113, 123 allowing the pivoting of the fixing lugs 110, 120, during the ascent, the claws 25 of the electrical box 20, which slide along these ramps 115, 125, cause the spreading outwardly in the deployed position of said fixing lugs 110, 120 whose teeth 114A, 124A of the ribs 114, 124 located on the outer face 112, 122 of the fixing lugs 110, 120, abut and anchor in the rear face 12 of the wall 10.
    [0018] It is therefore understood that the deployed intermediate position taken by the fixing lugs 110, 120 after anchoring the mounting frame 100 in the rear face 12 of the wall 10 depends on the thickness of this wall 10, so that the fixing lugs 110, 120 are all the more deployed that the wall 10 is thinner.
    [0019] The fastening lugs 110, 120 of the mounting frame 100 clamped by the claws 25 against the wall 10, can no longer move apart and fix, thanks to the teeth 114A, 124A of the ribs 114, 124, the mounting frame 100 in FIGS. the hole 13 of the wall 10. Moreover, in this deployed position, the claws 25 of the electrical box 20 clamped against the ramps 115, 125, fix the electrical box 20 on the mounting frame 100. By screwing the screws 26 of claw of the electrical box 20, then simultaneously performs a double clamping: a first clamping of the fastening lugs 110, 120 against the wall 10 for fixing the mounting frame 100 in the wall 10, and a second clamping of the claws 25 against the fixing lugs 110, 120 for fixing the electrical box 20 to the mounting frame 100. Thus, thanks to the fixing lugs 110, 120 of the mounting frame 100, the installer has only one operation of screwing to perform to achieve this double squeeze ge. The installation of the electrical box 20 in the hole 13 of the wall 10 is thus greatly simplified. The use of the mounting frame 100 according to the invention does not introduce for the installer additional screwing operation compared to the usual screwing operations for fixing the electrical box 20 in the wall 10.
    [0020] For the dismantling of the electrical box 20 and the mounting frame 100, it is sufficient that the installer unscrews the claw bolts 26 of the electrical box 20 to lower the claws 25 along the threaded body of the screws 26. In descending, the claws 25 no longer exert pressure on the fixing lugs 110, 120 of the mounting frame 100 which return elastically in the retracted position. The installer can then extract the whole of the hole 13 of the wall 10. The present invention is not limited to the embodiments described and shown, but the skilled person will be able to make any variant within his mind.5
