In the following description, by convention, the term "front" will designate the side of the element described facing a user when this element is in the position of use on a wall, while the term "rear" will designate the side opposite of this element, facing the inside of the wall.

There is shown in Figures 1 and 17, in closed and open configurations, a multi-device device according to the invention to be attached in an opening of a receiving wall (not shown).

Advantageously, but not exclusively, such a multi-equipment device is intended to be mounted in the opening of a wall of office furniture such as a work table or a reception counter or even any storage unit.

This multi-device device advantageously comprises a mounting frame 1, shown as a whole in FIG. 2, and a multi-device box 6, shown more particularly in FIG. 3, attached to mounting devices 10 of the mounting frame 1 .

The remarkable characteristics of each mounting device 10 will be described in detail in the following text.

As shown in FIG. 3, the multi-equipment box 6, commonly called an equipment feeder, has a rectangular parallelepipedic shape, with two parallel longitudinal walls 60, held at a fixed distance determined from each other by covers 80 snapped onto arrangements of a rear part forming the foot of said longitudinal walls 60 and by end pieces 70, attached to the two opposite ends of the multi-device box 6 and fixed using screws V2 on the ends of the longitudinal walls 60 .

The various aforementioned elements constituting the structure of the multi-device box 6 are each formed from a single piece of molded plastic material, whether or not loaded with fiberglass or light metal material such as aluminum.

Thus, the multi-device box 6 has two parallel longitudinal faces 6A, two parallel end lateral faces 6D as well as a parallel front face 6B and a rear face 6C.

The front face 6B of the multi-device box 6 is formed by the front faces of the decorative plates 50 of the devices 51, 52, 53 and 54 attached to the multi-device box 6. The decorative plates 50 are positioned contiguous so that they close the entire front longitudinal opening of the multi-device box 6, defined between the longitudinal returns facing said longitudinal walls 60.

A front edge 71 of each end piece 70 extends in the extension of the front face 6B of the multi-device box 6.

Finally, the rear face 6C of the multi-device box 6 carries a connector 90 to which the various devices 51, 52, 53, 54 placed in the box are connected. This 90 connector is intended to be connected to the local power supply network. As a variant, this connector can be replaced by a connection cable outlet for these devices.

The mounting frame 1 is intended to be fitted in the opening of the receiving wall, the dimensions of this opening (not shown) being adapted to that of the mounting frame 1.

As shown more particularly in Figures 1 and 2, the mounting frame 1 comprises two parallel longitudinal walls 20, held at a fixed distance determined from one another by fixed supports 100 of two mounting devices 10 mounted at each end of said longitudinal walls 20, a cover 3 attached to cover elements 300 of said mounting device 10 to close a major part of a front longitudinal opening O of the mounting frame 1, a hatch 4 mounted to tilt on the fixed supports 100 of said mounting devices 10 so as to close the part of said front longitudinal opening O not closed by cover 3 (see figure 17) and a finishing plate 2 in the form of a frame added around cover 3 and hatch 4 (see Figure 17).

The longitudinal walls 20 are preferably extruded aluminum sections.

They have a rectangular shape delimited between a free longitudinal edge 21A and a rear longitudinal edge 21B.

A rear part of each of said longitudinal walls 20, which extends from the free rear longitudinal edge 21B of each longitudinal wall 20 over a small part of its height, forms a first groove 26C with a rounded bottom, open towards the rear and at each of its ends, which runs along the outer face 20A of the longitudinal wall 20, over the entire length of said longitudinal wall 20. The inner faces facing each first groove 26C are grooved.

In addition, each longitudinal wall 20 comprises on its outer face 20A, close to its free front longitudinal edge 21A, first and second longitudinal ribs which extend lengthwise in directions parallel to said front longitudinal edge 21A, and which present facing concave internal faces, together defining a second groove 23C with a cylindrical profile, open at both ends and comprising a front longitudinal opening oriented in a direction perpendicular to the external face 20A of said longitudinal wall 20.

As shown more particularly in Figures 1, 4, 5 and 6, the fixed support 100 of each mounting device 10 is in the form of a cheek delimited by a front longitudinal edge 101A, a rear longitudinal edge 101B, an edge front side 101C and a rear side edge 101D. The fixed support 100 comprises an outer face 100A facing the outside of the mounting frame 1 and an inner face 100B facing the inside of the mounting frame 1.

As shown more particularly in Figures 4, 5 and 6, the internal face 100B of each fixed support 100 comprises along the front 101C and rear 101D side edges, two recesses 103. Each recess 103 leads to a front 101C or rear side edge 101D of the fixed support 100 and it is delimited on three sides by a flange 103A. Each fixed support 100 has through holes 104 which open on one side onto the bottom of said recesses 103. Two holes 104 are provided per recess 103, one of the holes 104 being located close to the front longitudinal edge 101A of the fixed support 100 while the other orifice 104 is located near the rear longitudinal edge 101B of said fixed support 100.

As shown more particularly in Figure 17, each end side edge of each longitudinal wall 20 is positioned in a recess 103 of the fixed support 100 of a mounting device 10, resting against a rim 103A delimiting said recess 103, so that the open ends of the first and second grooves 26C, 23C are positioned opposite said orifices 104 passing through the fixed supports 100.

The fixed supports 100 are fixed to said longitudinal walls 20 by screws V1 screwed through said orifices 104 in said first and second grooves 26C, 23C (see FIGS. 1 and 2).

The longitudinal walls 20 and the fixed supports 100 of the mounting devices 10 thus assembled delimit an interior space suitable for receiving the multi-device box 6.

As shown in particular in Figure 17, at the front, the two longitudinal walls 20 delimit between them the front longitudinal opening O of the mounting frame 1, through which, on the one hand, said multi-device box is mounted 6 in the mounting parts 200 of the mounting devices 10, and, on the other hand, once said box has been mounted and connected to the local power supply network, the front face 6B of this box is accessed to connect plugs F to the various devices of this box 6.

At the front, each longitudinal wall 20 is provided with a clipping strip.

More specifically, as shown in Figure 17, each clip strip here comprises a longitudinal flange 28 attached by a spacer 27 to the inner face 20B of the longitudinal wall 20 corresponding.

Each longitudinal wing 28 and each associated spacer 27 are located inside the mounting frame 1 at a distance from the free front edge 21A of each longitudinal wall 20.

Each spacer 27 defines with the longitudinal flange 28 and the corresponding longitudinal wall 20, an internal longitudinal groove 29, open towards the front longitudinal opening O.

The front longitudinal opening O is therefore bordered longitudinally by the two internal longitudinal grooves 29, open towards the front of the mounting frame 1.

These two internal longitudinal grooves 29 are used to mount the finishing plate 2.

Indeed, as shown in Figures 1 and 2, this finishing plate 2 is in the form of a rectangular flat frame with a rectangular central opening 2A whose dimensions are equal except for clearance to those of the cover 3 and the hatch 4 side by side (see figure 1). It carries on its rear face, along the two parallel longitudinal edges of its central opening 2A, two clipping strips 2B which extend perpendicularly to said rear face and which are adapted to snap into said internal longitudinal grooves 29 of the walls longitudinal openings 20 so that the rectangular central opening 2A merges with the said front longitudinal opening O of the mounting frame 1 (see FIG. 17), the rear face of the said finishing plate 2 covering the front longitudinal edges 101A of the fixed supports 100 of the mounting devices 10 as well as the front longitudinal edges 21A of the two longitudinal walls 20.

The finishing plate 2 thus mounted has a part which projects outwards (see figure 17) to rest on the front face of the receiving wall (not shown) around the opening of said wall.

The cover 3 is a profiled plate made for example of aluminum. It has here a rectangular shape adapted to the shape of the front longitudinal opening O of the mounting frame 1 to be closed. The cover 3 has on its rear face slideways in which are threaded plates 5 suitable for mounting said cover 3 on cover elements 300 of mounting devices 10.

More particularly, there are provided two plates 5 threaded at the two ends of the cover 3, each plate 5 being used to mount the cover 3 on the cover element 300 of the corresponding mounting device 10.

As shown in Figure 2, the hatch 4 is in the form of a profiled strip.

It is also made for example of aluminum.

It comprises along its front longitudinal edge 4A a groove in which are threaded two Y axes which protrude from the end edges 4C of said hatch 4. The rear longitudinal edge 4B of the hatch 4 carries a 4D drive pin which protrudes an end edge 4C (the one on the right in Figure 2).

The Y axes are snapped into notches 102 provided on the front longitudinal edges 101A of the fixed supports 100 of the two mounting devices 10, close to the front side edges 101C of said fixed supports 100.

Thus, the hatch 4 is pivotally mounted, via its front longitudinal edge 4A, on the fixed supports 100 around said axes Y between a closed position (see FIG. 1) and an open position (see FIG. 17). As shown in Figure 17, in the open position, the hatch 4 clears a passage towards the inside of the mounting frame 1 for the power supply cable C of a plug F plugged into a device of the multi-device box 6 reported in the mounting parts 200 of the mounting devices 10.

The front longitudinal edge 4A of the hatch 4 adjoins a longitudinal edge of the rectangular central opening of the finishing plate 2 while, when the hatch 4 is in the closed position, as shown in FIG. 1, the two edges of end 4C of this hatch 4 adjoin a part of the side edges of the rectangular central opening of said finishing plate 2 and the rear longitudinal edge 4B of the hatch 4 adjoins the front longitudinal edge of the lid 3 in the closed position.

When the hatch 4 is mounted on the fixed supports 100, the drive stud 4D extends from inside the mounting frame 1, through a guide slot 107 provided on the fixed support 100 of the mounting device 10 corresponding (the one on the right in Figures 1 and 2). The guide light 107 extends along an arc of a circle. The 4D drive pin bears against an end strand 802 of a wire spring 800 wound around a stud 105 carried by the outer face 100A of said fixed support 100, close to said guide slot 107. another end strand 801 of the wire spring 800 is wedged behind a retaining stop 106 also provided on the outer face 100A of the said fixed support 100. The wire spring 800 is thus mounted under stress on the outer face 100A of the fixed support 100.

The wire spring 800 is more particularly shown in Figure 4.

The end strand 802 of the wire spring 800 permanently pushes the 4D drive pin of the hatch 4 forwards of the mounting frame 1 to permanently return the hatch 4 to the closed position, in the plane of the rectangular central opening of the cover plate 2, as shown in figure 1.

To open the hatch 4, it suffices to press on it to make it pivot towards the inside of the mounting frame 1. The drive stud 4D then navigates in the guide slot 7 of the fixed support 100 to guide the pivoting movement of the hatch 4 by pushing the end strand 802 of the wire spring 800 (see FIG. 17) so that this wire spring 800 stores torsion energy.

As soon as the pressure on the hatch 4 is released, the wire spring 800 releases the stored energy and its end strand 802 pushes the drive pin 4D of the hatch 4 forwards of the assembly frame 1. -it navigates in the guide slot 107 of the fixed support 100 and automatically drives the hatch 4 which pivots from its open position (Figure 17) to its closed position (Figure 1).

We will now describe in detail the remarkable common characteristics of the two mounting devices 10 of the mounting frame 1.

Indeed, the two mounting devices 10 are essentially identical, with the differences that, on the one hand, the drive arrangements of the door 4 which have just been described are located only on the mounting device of right, and, that, on the other hand, as will be explained in detail later, the fixed support of the right-hand mounting device comprises, recessed on its internal face, a cam track, one edge of which is notched along its entire length while the edge of the cam track provided recessed on the inner face of the fixed support of the left mounting device, is notched over only part of its length.

The mounting device 10 on the right is shown more particularly in Figures 4 and 5, while the mounting device 10 on the left is more particularly shown in Figure 6.

In the remainder of the description, for greater convenience, reference will be made to a mounting device, but this obviously relates to the two mounting devices.

The assembly device 10 comprises the cover element 300 pivotally mounted on the fixed support 100, means for automatically opening the cover element 300 comprising, on the one hand, a main elastic element 500 acting on said element cover 300 to cause a tilting movement from a closed position to an open position, and, on the other hand, damping means 400, 110 acting between said cover element 300 and said fixed support 100 during said tilting movement to control and dampen the stroke of said cover element 300.

Remarkably, the mounting device 10 comprises the mounting part 200, distinct from the said cover element 300, pivotally mounted on the fixed support 100 and adapted to receive an end piece 70 of the said multi-device box 6.

Also remarkably, in the mounting device 10, drive means 321, 221, provided on said cover element 300 and on said mounting part 200, cooperate in such a way that, during only part of the tilting movement said cover element 300, said cover element 300 causes the mounting part 200 to tilt from a closed position to an open position giving access to the front of the multi-device box 6.

The fixed support 100, the cover element 300 and the mounting part 200 are one-piece parts preferably made of rigid plastic material.

Figures 1 and 5 show the assembly device 10 assembled in the position of use.

As has already been described above, the fixed support 100 is in the form of a cheek delimited by a front longitudinal edge 101A, a rear longitudinal edge 101B, a front side edge 101C and a rear side edge 101D. The fixed support 100 has an internal face 100B facing the cover element 300 and the mounting part 200 as well as an external face 100A opposite to said internal face 100B.

The cover element 300, more particularly represented in FIGS. 7 and 8, comprises a generally rectangular support plate 310 with a parallel, opposite front face 310A and rear face 310B.

In use, the front 310A and rear 310B faces of the support plate 310 of the cover element 300 extend in planes perpendicular to the plane of the internal face 100B of the fixed support 100.

The front face 310A of the support plate 310 is intended to receive a plate 5 for mounting cover 3. It carries protruding tabs 312, two of which are arranged along a longitudinal edge 311A of the support plate and the third of which is placed close to the other opposite longitudinal edge 311B of said support plate 310. These tabs 312 are capable of snapping into the corresponding openings 5A of the plate 5 for mounting the cover 3 to secure the cover 3 to the said support plate 310 Two notches 313 are also provided in the longitudinal edge 311B of the support plate 310. These notches 313 are intended to receive two studs 5B (see FIG. 17) carried by the rear face of the plate 5 to center the cover 3 on said support plate 310 of the cover element 300.

As shown in Figures 7 and 8, the cover member 300 has a mounting wall 320 which extends from the rear face 310B of the support plate 310, perpendicular thereto. This mounting wall 320 has an outer face 320A facing the inner face 100B of the fixed support 100 and an inner face 320B parallel and opposite to said outer face 320A. In use, the external 320A and internal 320B faces of this mounting wall 320 are essentially parallel to the internal 100B and external 100A faces of the fixed support 100.

Finally, in a corner of the support plate 310, opposite the mounting plate 320, the cover element 300 includes a locking pin 327 which extends from the rear face 310B of the support plate 310 , perpendicular to it. This locking pin 327 comprises two teeth 327A at its free end. It is intended to be locked in an automatic locking latch 700 secured to the fixed support 100.

More specifically, the automatic locking latch 700 is placed in the housing 192 of a support 190 carried by the internal face 100B of the fixed support 100 and it is held in this housing 192 by retaining lugs 191.

The latch 700 comprises a body 701 movable in a casing and carrying at its free end two locking tongues 702 articulated on the body 701 by a hinge connection. When the locking pin 327 of the cover element 300 exerts pressure on the body 701 of the latch 700, it pushes it into its housing and the locking tabs 702 fold up against the teeth 327A of the locking pin 327 to retain it attached to the body 701. This recessed position of the body 701 in the housing of the latch 700 is automatically locked by a cam system. To release the body 701 from the latch 700, it suffices to exert a new pressure on the latter so as to unlock the cam system. The released body 701 rises in the housing of the latch 700. The tabs 702 then come out of said housing and open to detach from said teeth 327A of the locking pin 327 of the cover element 300.

The mounting part 200 comprises a main plate 210 with a square outline with an external face 210A facing the cover element 300 and an internal face 210B opposite.

In use, the external 210A and internal 210B faces of the main plate 210 of the mounting part 200 are parallel to the external 320A and internal 320B faces of the mounting wall 320 of the cover element 300.

The internal face 210B of the main plate 210 is bordered on three contiguous sides by three walls 220A, 220B. The three walls 220A, 220B extend perpendicular to said main plate 210. The walls 220A, 220B delimit with the inner face 210B of the main plate 210 a housing for receiving an end piece 70 of the multi-device box 6. This housing reception comprises a bottom formed by the internal face of the wall 220B and an inlet opening which opens onto the fourth side 210C of the internal face 210B of the main plate 210. As shown in FIG. 17, the endpiece 70 is engaged in the housing for receiving the mounting part 200 in such a way that a lateral end face 6D of the multi-device box 6 is pressed against the internal face 210B of the main plate 210 and that three of the sides of the tip 70 bear against the internal faces of said walls 220A, 220B of the mounting part 200. A tongue 213 is cut in the main plate 210 and carries a tooth 213A which protrudes from the internal face 210B of the main plate 210 This tooth 213A is adapted to hook onto the front edge 71 of the end piece 70 of the multi-device box 6 engaged in the housing for receiving the mounting part 200 to retain said end piece 70 in said reception housing. Once mounted in the housing for receiving the mounting part 200, the front face 6B of the multi-device box 6 faces the fourth side 210C of the main plate 210 of said mounting part 200.

The external face 210A of the main plate 210 of the mounting part 200 is visible in FIGS. 9 and 10. This external face 210A is bordered on one side by a reinforcing wall 215. It carries a cylindrical duct 240 which extends perpendicular to this outer face 210A. The cylindrical duct 240 is open at both ends so that it opens through a circular opening 212 on the internal face 210B of the main plate 210. The cylindrical duct 240 is engaged on a chimney 160 carried by the internal face 100B of the support fixed 100 for the pivoting mounting of the mounting part 200 on the fixed support 100. It is then understood that the internal diameter of the cylindrical duct 240 is slightly greater than the external diameter of the chimney 160 so that the external face of the chimney 160 forms a surface for guiding the cylindrical duct 240 in rotation. The chimney 160 has an internal thread and a locking screw V is inserted through the said circular opening 212 through the said cylindrical duct 240 of the mounting part 200 to be screwed into the chimney 160 in order to lock the assembly part 200 on the fixed support 100.

Advantageously, angular abutment means 180, 230 are provided adapted to place said mounting part 200 in abutment against the fixed support 100 in its closed and open positions as well as to limit the tilting travel of said mounting part 200 in such a way independent of the tilting movement of the cover element 300.

These angular stop means 180, 230 are arranged to limit the tilting stroke of said mounting part 200 to an angular sector of approximately 65 degrees between its closed and open positions.

As shown more particularly in Figures 9 and 10, the angular stop means comprise a groove 230 arranged on the outer face 210A of the main plate 210 of the mounting part 200, having a closed contour of oblong shape curved along an arc of 65 degree circle. The groove 230 is delimited by a wall 231 carried by the outer face 210A of the main plate 210 of the mounting part 200. The groove 230 has two opposite end edges 230A, 230B, which are rounded. The angular stop means also comprise a cylindrical stud 180 extending perpendicularly to the internal face 100B of the fixed support 100, engaged in said groove 230, adapted to bear against each of the two end edges 230A, 230B of said groove 230 and to navigate from one end edge 230A to the other 230B of said groove 230 by sliding along the longitudinal edges 231A of groove 230 during the tilting movement of said mounting part 200.

The abutment of said cylindrical stud 180 of the fixed support 100 against the end edge 230A of the groove 230 of the mounting part 200 fixes the closed position of said mounting part 200 (as shown in Figures 9 and 10), while the abutment of said cylindrical stud 180 of fixed support 100 against the other end edge 230B of groove 230 of mounting part 200 fixes the open position of said mounting part 200.

The main elastic element 500 which causes most of the tilting movement of the cover element 300 is a torsion wire spring with a diameter of 1.4 mm, having a relatively large section, wound around a cylindrical stud 170 carried by the internal face 100B of the fixed support 100. One of the end strands 502 of the wire spring 500 is held on the fixed support 100 by a hook 140A. The other end strand 501 of the wire spring 500 is engaged in a groove 360 (visible in FIGS. 7, 8 and 9) provided on the outer face 320A of the mounting wall 320 of the cover element 300, when said cover element 300 is in the closed position and over the majority of the tilting movement of the cover element 300 between its closed and open positions (as will be explained in more detail later with reference to Figures 11 to 16 ). This end strand 501 of the wire spring 500 releases said cover element 300 at the end of its opening movement, when said end strand 501 locks against a stop 140B carried by the internal face 100B of the fixed support 100.

Preferably, there is provided an auxiliary elastic element 600 interposed under stress between said cover element 300 and said mounting part 200 to push said cover element 300 during a first phase of opening while maintaining said mounting part 200 positioned in the closed position in abutment against said fixed support 100 (the cylindrical stud 180 of the fixed support 100 bears against the end edge 230A of the groove 230 of the mounting part 200).

As best shown in Figures 7 and 8, this auxiliary elastic element 600 is a torsion wire spring, wound around a pad 323 of axis X3 extending projecting from the outer face 320A of the mounting wall 320 of the cover element 300, whose two end strands 601, 602 are engaged behind retaining lugs 370, provided on said outer face 320A, so that they are held against said cover element 300. A part of one of the two end strands 601 of said wire spring 600 being hooked by a hook 270 attached to the outer face 210A of the main plate 210 of said mounting part 200 (see FIGS. 9 and 10).

The auxiliary wire spring 600 has a section smaller than that of the main wire spring 500.

The pivoting mounting of the cover element 300 on the fixed support 100 is ensured by said damping means as well as by various guide elements which will be described below.

Advantageously, said damping means comprise, on the one hand, a cam track 110 provided hollow on the internal face 100B of the fixed support 100, notched over at least part of the length of one of its longitudinal edges, and , on the other hand, a toothed wheel 400 mounted for free rotation on the outer face 320A of the mounting wall 320 of the cover element 300, said toothed wheel 400 being adapted to be inserted in said cam track 110 so that its teeth cooperate with the notches 112 of said cam track 110 during the tilting movement of said cover element 300.

As shown in Figures 4, 6, 7 and 8, the toothed wheel 400 is a pinion mounted for free rotation on an axis 412 of a support 410 provided with two latching lugs 411. The support 410 is inserted into a housing 340 formed on the outer face 320A of the mounting wall 320 of the cover element 300 so that its snap-fastening lugs 411 hook onto the edge of openings provided at the bottom of said housing 340. Thus mounted, the wheel toothed 400 is placed parallel to the outer face 320A of said mounting wall 320 of the cover element 300.

The cam track 110 is delimited by two longitudinal edges and a bottom 111 (see figure 1) so that it does not open onto the outer face 100A of the fixed support 100.

The cam track 110 of the fixed support 100 of the mounting device 10 on the right shown in FIG. 4 is notched over the entire length of one of its longitudinal edges, while the cam track 110 of the fixed support 10 left shown in Figure 6, is notched on only part of the length of one of its longitudinal edges.

According to a particularly advantageous characteristic, the cam path 110 comprises four parts corresponding to four phases of the tilting movement of the cover element 300, namely, said cam path 110 comprises, from a front end 110A to a rear 110F, a first part 110B in an arc of a circle, a second inclined straight part 110C, a third part 110D in an arc of a circle and a fourth straight straight part 110E.

The second rectilinear part 110C of the cam path 110 is slightly inclined from the front to the rear of the fixed support 100.

The first part 110B of the cam track 110 is adapted to control the tilting movement of the cover element 300 over an angle of approximately 25 degrees, the second part 110C of the cam track 110 is adapted to cause a shift in translation said cover element 300 over a distance of approximately 3 millimeters, the third part 110D of the cam track 110 is adapted to control the tilting movement of the cover element 300 over an angle of approximately 65 degrees and the fourth part 110E of cam track 110 is adapted to control the rocking motion of cover member 300 through an angle of approximately 12 degrees.

On the fixed support 100 of the mounting device 10 on the left, represented in FIG. 6, the first part 110B of the cam track 110 has smooth, non-serrated longitudinal edges.

The fact of notching the entire longitudinal edge of the cam track 110 of the fixed support 100 of a mounting device 10 on both of the mounting frame 1 makes it possible to adapt the force necessary for the first phase of automatic opening of the cover 3 to the force of the spring.

Means for guiding the cover element 3 are also provided.

These guide means comprise a main groove 120 in the fixed support 100 and a guide finger 322 projecting from the outer face 320A of the mounting wall 320 of said cover element 300, slidably engaged in the main groove 120.

This main groove 120 is a slot which opens onto the inner 100B and outer 100A faces of the fixed support 100. It extends beside the cam track 110 along a path parallel to the path explained above of the cam track 110. correspondence, the guide finger 322 is positioned on the outer face 320A of the mounting wall 320 of the cover element 3, just next to the toothed wheel 400. It extends along an axis X2 parallel to the axis X3, perpendicular to said outer face 320A. The groove 360 for engaging the end strand 501 of the wire spring 500 is located behind a base from which the guide finger 322 extends (see FIGS. 7, 8 and 9).

Thus, just like said cam track 110, said main groove 120 comprises four parts corresponding to four phases of the tilting movement of the cover element 300, namely, said main groove 120 comprises, from a front end 120A to a rear end 120F, a first part 120B in an arc of a circle, a second inclined rectilinear part 120C, a third part 120D in an arc of a circle and a fourth straight rectilinear part 120E.

The second rectilinear part 120C of the main groove 120 is slightly inclined from the front to the rear of the fixed support 100.

The first part 120B of said main groove 120 is adapted to guide the tilting movement of the cover element 300 over an angle of approximately 25 degrees, the second part 120C of said main groove 120 is adapted to cause a shift in translation of said cover element 300 over a distance of approximately 3 millimeters, the third part 120D of said main groove 120 is adapted to guide the tilting movement of the cover element 300 over an angle of approximately 65 degrees and the fourth part 120E of said main groove 120 is adapted to guide the tilting movement of the cover member 300 over an angle of approximately 12 degrees.

Auxiliary guide means are also provided which intervene, on the one hand, between the cover element 300 and the fixed support 100, and, on the other hand, between the cover element 300 and the mounting part 200 .

These guide means comprise on the outer face 320A of the mounting wall 320 of the cover element 300, the cylindrical stud 323 extending along the axis X3, around which the auxiliary wire spring 600 is wound, which is engaged in an elbow-shaped groove 130, formed hollow on the internal face 100B of the fixed support 100. This elbow-shaped groove 130 extends around the chimney 160 on which the mounting part 200 is rotatably mounted. is a blind groove which is closed by a bottom 131 on the side of the external face 100A of the fixed support 100. The auxiliary guide means also comprise an angled wall 150 carried by the internal face 100B of the fixed support 100 which forms a ramp on which slides a complementary ramp 350 carried by the cover element 300 along the rear edge 321B of the mounting wall 320. Said angled wall 150 of the fixed support 100 extends between the cylindrical stud 170 and the groove 130, along of the latter. The complementary ramp 350 is formed by an angled wall which extends in width perpendicular to the internal face 320B of the mounting wall 320. The auxiliary guide means provided between the cover element 300 and the mounting wall 320, comprise on the inner face 320B of the mounting wall 320 of the cover element 300, a cylindrical finger 324 which extends along the axis X3. Cylindrical finger 324 and cylindrical stud 323 extend along the same axis X3 opposite each other (see Figure 7). This cylindrical finger 324 is engaged in an oblong slot 214 which crosses the main plate 210 of the mounting part 200.

Said drive means which intervene between the cover element 300 and the mounting part 200 comprise a drive finger 321 projecting from the internal face 320B of the mounting wall 320 of the cover element 300 engaged in a light 221 provided in the main plate 210 of said mounting part 200. This light 221 has an L-shape with a first part 221A and a second part 221B which is connected by an elbow. The second part 221B comprises a part with a bottom which extends beyond the main plate 210. The drive finger 321 is provided at the end of a pin which extends from said internal face 320B along an axis X1 perpendicular to said internal face 320B.

The means for guiding the cover element 300, distinct from said driving means and said damping means described above, which, associated with said driving means and said damping means, cause a fluid tilting movement without jamming of the cover element 300 and said mounting part 200.

With reference to Figures 11 to 16, we will now describe the opening and closing movements of the cover 3 of the mounting frame 1, attached to the cover elements 300 of the two mounting devices 10, as well as concomitantly, the opening and closing movements of the associated mounting parts 200.

The different phases of these movements will be broken down but, of course, they take place continuously one after the other without jerking or jamming.

FIG. 11 shows, seen from the internal and external sides, the mounting device 10 on the left of the mounting frame 1 closed by the cover 3 (as in FIG. 1). The cover element 300 which supports the cover 3, in the closed position, extends horizontally so that the cover closes the front longitudinal opening O of the mounting frame 1. The locking pin 327 of the cover element 300 is locked in the latch 700. The mounting part 200 in the closed position has its receiving housing with its entry opening inclined rearwardly by 25 degrees relative to the vertical materialized by the axis V. In this position , the auxiliary wire spring 600 is bonded under stress to said cover element 300 and to said mounting part 200. The main wire spring 500 is also bonded under stress to said cover member 300 and to the fixed support 100. The drive finger 321 of the cover element 300 is blocked near the end of the first part 221A of the slot 221 of the mounting part 200. The cylindrical stud 180 of the fixed support 100 (not visible) is in abutment against an edge of end 230A of the groove 230 of the mounting part 200. Finally, the guide finger 322 of the cover element 300 is placed close to the front end 120A of the main groove 120 of the fixed support 100 and the wheel gear 400 (not visible) is positioned near the front end 110A of the cam track 110.

A user exerts a short pressure on the cover 3 so as to push the locking pin 327 and the body 701 of the latch 700 into the housing of the latch 700.

As shown in Figure 12, this has the effect of releasing the locking pin 327 from the locking tabs 702 of the latch 700. The auxiliary wire spring 600 immediately pushes the lid member 300 to open the lid 3 by an angle A equal to 25 degrees. The toothed wheel 400 of the cover element 300 rolls in the first part 110B of the cam track 110 of the fixed support 100 by cooperating with the notches 112 to control the tilting of said cover element 300 and therefore of the cover 3. The finger of guide 322 of the cover element 300 traverses the first part 120B of the main groove 120 of the fixed support 100. In this first phase of opening of the cover 3, the mounting part 200 does not move because the drive finger 321 of the cover element 300 which navigates in the slot 221 of the mounting part 200 does not press on the edges of this slot 221. In addition, the auxiliary wire spring 600 keeps said mounting part 200 in abutment against the support 100. More specifically, it holds the end edge 230A of the groove 230 of the mounting part 200 in abutment against the cylindrical stud 180 of the fixed support 100.

The main 500 wire spring then takes over from the auxiliary 600 wire spring and pushes the cover element 3 to tilt it towards the inside of the mounting frame 1.

In doing so, as shown in Figure 13, the guide finger 322 of the cover element 300 travels the second rectilinear part 120C of the main groove 120 which has the effect of translating the cover element 300 (and therefore the cover 3) a few millimeters rearwards and to position the drive finger 321 against the edge of the slot 221 of the mounting part 200. The toothed wheel 400 of the cover element 300 also rolls in the second rectilinear part 110C of the cam track 110 by cooperating with the notches 112 of the latter to control the movement of the cover element 300. The cover element 300 then causes the tilting of the mounting part 200.

As shown in Figures 14 and 15, the cover element 300, supporting the cover 3, and the mounting part 200, supporting one end of the multi-device box 6, not shown in these figures for greater clarity, tilt together at an angle of 65 degrees under the thrust of the wire spring 500 which releases the stored energy and relaxes. During this opening phase, the guide finger 322 of the cover element 300 navigates in the third part 120D of the main groove 120 of the fixed support 100. The toothed wheel 400 of the cover element 300 rolls, cooperating with said notches 112, in the third part 110D of the cam track 110 of the fixed support 100. The drive finger 321 navigates along the second part 221B of the slot 221 of the mounting part 220 by sliding against the edge of this lumen 221. The cylindrical finger 324 of the cover element 300 navigates in the oblong lumen 214 of the mounting part 200.

At the end of this opening phase, as shown in Figure 15, the cover element 300 with the cover 3 are tilted inside the mounting frame 1, at about 90 degrees from their closed position. They leave clear the front longitudinal opening O of the mounting frame 1. The mounting part 200 is positioned in the open position, resting on the fixed support 100. Indeed, in this open position, the other end edge 230B of the groove 230 of said mounting part 200 bears against the cylindrical stud 180 of the fixed support 100. The mounting part 200 can therefore no longer go further in its tilting. In this open position of the mounting part 200, the entry opening in the receiving housing of the mounting part 220 is positioned horizontally (that is to say at 90 degrees with respect to the vertical V) facing to the front longitudinal opening O of the mounting frame 1. The front face 6B of the multi-device box 6 (not shown here) which overlooks this entry opening therefore faces the front longitudinal opening O of the mounting frame 1 and the apparatuses of this box are accessible to the user.

It is important to note that at the end of this opening phase, the main wire spring 500 is relaxed to the maximum and its end strand 501 is locked against the stop 140B of the fixed support 100. It does not is therefore no longer in engagement with the groove 360 of the cover element 300. The end strand 601 of the auxiliary wire spring 600 is also no longer in engagement with the hook 270 of the mounting part 200 (as shown on Figure 15 where we can see the hook 270 alone in the window of the main plate 210 of the mounting part 200).

As shown in Figure 16, the cover member 300 (and the cover 3 supported by it) is then free from the tension of the wire springs 500, 600 and continues to tilt under its own weight inside the frame. mounting 1 to take an opening inclination of an angle B of about 12 degrees behind the vertical V. The mounting part 200 remains stationary in the open position. During this last phase of opening, the guide finger 322 of the cover element 300 navigates in the fourth rectilinear part 120E as far as the rear end 120F of the main groove 120 of the fixed support 100. The toothed wheel 400 of the cover element 300 rolls, cooperating with said notches 112, in the fourth part 110E as far as the rear end 110F of the cam track 110 of the fixed support 100. The drive pin 321 navigates along the second part 221B to the end of the slot 221 of the mounting part 220 by sliding against the edge of this slot 221. The cylindrical finger 324 of the cover element 300 navigates in the oblong slot 214 of the mounting part 200 to the end of this light 214.

Lid 3 is completely open. Its opening inclination facilitates access to the interior of the mounting frame 1, and therefore to the multi-device box 6 attached to this frame.

It should be noted that in this position, the cylindrical fingers 321, 324 are in the low position in the respective slots 221, 214, which causes advantageous locking of the multi-device box so that it remains immobile during inserting or removing an electrical plug.

Throughout this aforementioned tilting movement of the cover element 3, the cylindrical stud 323 of the cover element 300 navigates in the angled groove 130 of the fixed support 100 and the complementary ramp 350 of the cover element 300 slides the along the ramp 150 of the fixed support.

To close the cover 3 from its open position, it suffices to manually grab one end of the latter which protrudes from the front longitudinal opening O of the mounting frame 1 (see figure 16) and to pull it towards the hatch. 4 until the locking pin 327 of the cover element 300 is locked in the latch 700. The cover element 300 and the mounting part 200 are then tilted in the opposite direction towards their original closed position.

During reverse tilting, the groove 360 of the cover element 300 catches in passing the end strand 501 of the wire spring 500 to put this wire spring 500 back under tension. The hook 270 of the mounting part 200 catches the end strand 601 of the auxiliary wire spring 600 in passing to also put this wire spring 600 back under tension.

The guide pin 322 of the cover element 300 rises in the main groove 120 of the fixed support 100. The toothed wheel 400 of the cover element 300 rolls, cooperating with said notches 112, in the cam track 110 of the fixed support 100. Drive finger 321 navigates along lumen 221 of mounting piece 220.

It will be noted that the passage of the guide finger 322 in the second rectilinear part 120C of the main groove 120 and the simultaneous passage of the toothed wheel 400 in the second rectilinear part 110C of the cam track 110, make it possible to shift said cover element 300 slightly forward to remove the drive finger 321 from its support against the edge of the slot 221 of the mounting part 200. The mounting part 200 having arrived at its closed position (see FIG. 12), the element cover 300 which is no longer in engagement with the mounting part 200 continues its tilting movement alone towards its closed position shown in Figure 11.

The present invention is not limited to the embodiment described and shown in the various figures, but those skilled in the art will know how to make any variant in accordance with their spirit.
