According to the invention, the device comprises a mounting member (200) pivotally mounted on the fixed support and drive means (321, 221) which cooperate such that the cover element drives the mounting member to flip between the closed position and the open position during only a partial flip movement of the cover element.

Description

Mounting device for a multiple equipment enclosure, mounting frame comprising such a mounting device and multiple equipment arrangement comprising such a mounting frame and multiple equipment enclosure

Technical Field

The present invention relates generally to the insertion of multiple equipment devices in openings in the walls of furniture of the office furniture type.

More specifically, the present invention relates to a mounting device for mounting a multiple equipment cabinet in an opening of a receiving wall, this mounting device comprising a cover element pivotally mounted on a fixed support, the automatic opening means of the cover element comprising, on the one hand, a main elastic element acting on said cover element to cause a tilting movement from a closed position to an open position, and, on the other hand, damping means acting between said cover element and said fixed support during said tilting movement to control and damp the course of said cover element.

Background

A device of the above type is known, in particular, from documents WO2008154021 and US9395770, in which a cover element is associated with a multiple-device case to form a monolithic assembly pivotally mounted on a fixed support. According to the document, an elastic element acts on the monolithic assembly to flip it from the closed position to the open position, and damping means act between the monolithic assembly and the fixed support during the tilting movement.

Disclosure of Invention

In contrast to the above-mentioned prior art, the present invention proposes an improved device in which the element supporting the multiple device case and the cover element are two distinct (different, distinct, distinguishable) parts, the turning movements of which are coordinated.

More specifically, the invention proposes a mounting device in which the cover element is a distinct component from the multiple-equipment enclosure, in which a mounting component distinct from the cover element is provided, which is pivotally mounted on a fixed support and is adapted to receive a portion of the multiple-equipment enclosure, in which drive means are provided on the cover element and on the mounting component, which drive means cooperate with one another in such a way that, during only a partial tilting movement of the cover element, the cover element drives the mounting component to tilt (swing) from a closed position to an open position, allowing access to the front face of the multiple-equipment enclosure.

Advantageously, therefore, by means of the invention, it is possible to open the cover element at an angle greater than the opening angle of the multiple device case, thus facilitating access to the front face of said case. In addition, during the partial opening phase, the damping means act only on the cover element, which has a lower mass than the tank, which is easier to use, more efficient and more resistant, since it is subject to less mechanical losses.

Other non-limiting and advantageous technical features of the mounting device according to the invention are as follows, which can be applied alone or in mutually combinations in a technically possible manner:

-angle stop means are provided, adapted to place the mounting member against the fixed support in its closed and open positions, and to limit the overturning stroke of the mounting member independently of the overturning movement of the cover element;

-said angular stop means are arranged to limit the tilting travel of said mounting part within an angular sector of about 65 degrees between its closed and open positions;

on the one hand, the angular stop means comprise a groove provided on the outer surface of the mounting part, which groove has an elongated closed profile curved along an arc of a circle, and on the other hand, the angular stop means comprise a cylindrical stud (stub) extending perpendicularly to the inner surface of the fixed support, insertable into said groove, adapted to abut against each of the two end edges of said groove, and adapted to transition (travel) from one end edge to the other end edge of said groove by sliding along the longitudinal edge of the groove during the overturning of said mounting part;

-an auxiliary elastic element is provided, interposed under stress between the cover element and the mounting part, to push the cover element in a first opening phase and at the same time maintain the mounting part in a closed position against the fixed support;

-said auxiliary elastic element is a wire spring wound around studs projecting from the outer surface of the cover element, the two end extensions of this auxiliary elastic element being maintained against said cover element, a portion of one of the two end extensions of said wire spring being hooked by a hook attached to said mounting part;

-on the one hand, said damping means comprise a cam track (cam-like path) concavely provided on the inner surface of the fixed support and formed with serrations over at least a part of the length of one of its longitudinal edges, and on the other hand, said damping means comprise a toothed wheel freely rotatably mounted on the outer surface of the cover element, said toothed wheel being inserted into said cam track in such a way that its teeth cooperate with the serrations of said cam track during the turning movement of said cover element;

-the cam track is serrated over the entire length of one of its longitudinal edges;

the cam track comprises four portions corresponding to the four phases of the turning movement of the cover element, i.e. said cam track comprises, from the front end to the rear end, a first portion in the shape of a circular arc, a second portion in the shape of an oblique straight line, a third portion in the shape of a circular arc and a fourth portion in the shape of a vertical straight line;

-a first portion of the cam track is adapted to control the flipping motion of the cover element over an angle of about 25 degrees, a second portion of the cam track is adapted to translate the cover element out of alignment by a distance of about 3 mm, a third portion of the cam track is adapted to control the flipping motion of the cover element over an angle of about 65 degrees, and a fourth portion of the cam track is adapted to control the flipping motion of the cover element over an angle of about 12 degrees;

the drive means comprise a drive finger (finger drive) which is provided convexly on the inner surface of the cover element and is adapted to be inserted into a slot provided in the mounting part;

-cover element guiding means are provided, distinct from and associated with said driving means and said damping means, so that the cover element and the mounting part perform a smooth overturning movement without jamming;

-said guide means comprise a main slot in the fixed support and comprise a guide finger protrudingly provided on the outer surface of said cover element and slidingly inserted in said main slot;

the main channel comprises four portions corresponding to the four phases of the turning movement of the cover element, i.e. it comprises, from the front end to the rear end, a first portion in the shape of a circular arc, a second portion in the shape of an oblique straight line, a third portion in the shape of a circular arc and a fourth portion in the shape of a vertical straight line;

-a first portion of the main grooves is adapted to guide the flip movement of the cover element over an angle of about 25 degrees, a second portion of the main grooves is adapted to translate the cover element out of alignment by a distance of about 3 mm, a third portion of the main grooves is adapted to guide the flip movement of the cover element over an angle of about 65 degrees, and a fourth portion of the main grooves is adapted to guide the flip movement of the cover element over an angle of about 12 degrees.

The invention also proposes a mounting frame intended to be inserted in an opening of a receiving wall, comprising two parallel longitudinal walls which are maintained at a predetermined fixed distance from each other by means of two fixed supports of a mounting device according to the invention mounted at each end of said longitudinal walls; the mounting frame comprises a cover plate connected to a cover element of said mounting device to close a substantial part of the front longitudinal opening of the frame; the mounting frame comprises a trapdoor mounted overturned on a fixed support of the mounting device to close the portion of the front longitudinal opening not closed by the cover plate; the mounting frame includes a trim panel in the form of a frame and attached around the cover plate and the trapdoor.

Finally, the invention proposes a multi-equipment device intended to be mounted in an opening of a receiving wall, comprising the above-mentioned mounting frame and a multi-equipment cabinet mounted in a mounting part of the mounting device according to the invention.

Detailed Description

In the following description, by convention, the term "front" refers to the side of the element that is directed towards the user when the element is in the position of use on the wall, and the term "rear" refers to the opposite side of the element, i.e. the side directed towards the inside of the wall.

In fig. 1 and 17 a multi-device arrangement according to the invention is shown in a closed configuration and in an open configuration to be mounted in an opening of a receiving wall (not shown).

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

The multi-equipment device advantageously comprises a mounting frame 1-shown in its entirety in fig. 2-and a multi-equipment cabinet 6-shown in more detail in fig. 3-which is connected into a mounting device 10 of the mounting frame 1.

The multiple equipment enclosure 6 and each mounting device 10 are systems distinct from each other and therefore they have no common parts in a sense, but as will be explained later, they have portions that cooperate with each other so that the mounting devices 10 ensure a controlled turning of said multiple equipment enclosure 6 between the closed position and the open position.

The salient features of each mounting device 10 will be described in detail in the text that follows.

As shown in fig. 3, the multiple equipment enclosure 6, commonly called equipment box, has a rectangular parallelepiped shape with two parallel longitudinal walls 60, which maintain a predetermined fixed distance between each other by means of covers 80 that snap-fit onto the arrangement forming the rear part of the bearing portion of said longitudinal walls 60 and end pieces (collars, packets) 70 connected to the opposite ends of the multiple equipment enclosure 6 and fixed to the longitudinal walls 60 by means of screws V2.

The various elements described above that make up the structure of the multiple equipment cabinet 6 are each a single part (monolithic piece) made of moulded plastic material filled with light metal material, such as glass fibre or aluminium.

Thus, the multiple device case 6 has two parallel longitudinal surfaces 6A, two parallel lateral end surfaces 6D, and parallel front and

rear surfaces

6B, 6C.

The front surface 6B of the multi-device enclosure 6 is formed by the front surface of the panel (garnish) 50 of the

devices

51, 52, 53, and 54 connected to the multi-device enclosure 6. The panels 50 are arranged in a continuous butt joint so that they close the entire front longitudinal opening of the multiple equipment cabinet 6 defined between longitudinal folds with respect to said longitudinal walls 60.

The front flange 71 of each end piece 70 extends in extension of the front face 6B of the multiple equipment case 6.

Finally, the rear face 6C of the multi-device case 6 carries a connector 90 to which the

various devices

51, 52, 53, 54 housed in the case are connected. This connector 90 is intended to be connected to a local power supply network. In a variant, the connector may be replaced by a cable outlet of these devices.

The mounting frame 1 is intended to be mounted in an opening of a receiving wall, the size of which opening (not shown) is adapted to the size of the mounting frame 1.

More specifically, as shown in fig. 1 and 2, the mounting frame 1 comprises two parallel longitudinal walls 20, which are maintained at a predetermined fixed distance from each other by means of two fixed supports 100 of mounting devices 10 mounted at each end of said longitudinal walls 20, a cover plate 3, which is distinct from the multiple equipment cabinet 6 and is connected to a cover element 300 of said mounting devices 10 to close most of the front longitudinal opening O of the mounting frame 1, a trapdoor 4, which is mounted on the fixed support 100 of said mounting devices 10 so as to be able to flip (swing) in order to close the part of said front longitudinal opening O not closed by the cover plate 3 (see fig. 17), and a facing plate 2, in the form of a frame and connected around the cover plate 3 and the trapdoor 4 (see fig. 17).

Preferably, the longitudinal wall 20 is an extruded aluminum profile.

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

The rear portion of each of said longitudinal walls 20, extending over a small portion of its height starting from the free rear edge 21B of the respective longitudinal wall 20, forms a first recess 26C with a rounded bottom, open at each end and directed towards the rear, along the outer surface 20A of the longitudinal wall 20 over the entire length of said longitudinal wall 20. The opposing inner surfaces of each first groove 26C are grooved.

In addition, each longitudinal wall 20 comprises, on its outer surface 20A, in the vicinity of its free front edge 21A, a first and a second longitudinal rib extending in length along a direction parallel to said free front edge 21A and having opposite concave inner surfaces which jointly define a second groove 23C with a cylindrical profile, this second groove 23C being open at both ends and comprising a front longitudinal opening directed in a direction perpendicular to the outer surface 20A of said longitudinal wall 20.

More specifically, as shown in fig. 1, 4, 5 and 6, the fixed support 100 of each mounting device 10 is in the form of a cheek plate, which is delimited by a front longitudinal edge 101A, a rear longitudinal edge 101B, a front lateral edge 101C and a rear lateral edge 101D. The fixed bearing 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.

More specifically, as shown in fig. 4, 5 and 6, the inner surface 100B of each fixed support 100 comprises two recesses 103 along the front lateral edge 101C and the rear lateral edge 101D. Each recess 103 opens onto the front or rear

lateral edge

101C, 101D of the fixed support 100 and is delimited on three sides by a flange 103A. Each fixed support 100 comprises a through-going aperture 104 which opens on one side to the bottom of the recess 103. Each recess 103 is provided with two apertures 104, one 104 being located in the vicinity of the front longitudinal edge 101A of the fixed support 100 and the other 104 being located in the vicinity of the rear longitudinal edge 101B of said fixed support 100.

More specifically, as shown in fig. 17, each end side edge of each longitudinal wall 20 is located in a recess 103 of the fixed support 100 of the mounting device 10 and abuts against a flange 103A delimiting said recess 103, so that the open ends of the first and

second grooves

26C, 23C are opposite to said aperture 104 through the fixed support 100.

The fixed support 100 is fixed to said longitudinal wall 20 by means of a screw V1 which is screwed through said aperture 104 into said first and

second grooves

26C, 23C (see fig. 1 and 2).

The longitudinal walls 20 and the fixed support 100 of the mounting device 10 are thus assembled to define an internal space suitable for receiving the multiple equipment cabinet 6.

In particular, as shown in fig. 17, at the front, the two longitudinal walls 20 delimit between each other a front longitudinal opening O of the mounting frame 1 through which, on the one hand, said multi-device enclosure 6 is mounted in the mounting part 200 of the mounting device 10 and, on the other hand, the front surface 6B of the enclosure is accessible for connecting the plug F to the different devices of the enclosure 6 once said enclosure is mounted and connected to the local power supply network.

In the front, each longitudinal wall 20 is equipped with a gib.

More specifically, as shown in fig. 17, here each clip strip comprises a longitudinal wing 28 connected to the inner surface 20B of the respective longitudinal wall 20 by a stay 27.

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

Each stay 27 defines, together with the longitudinal wing 28 and the respective longitudinal wall 20, an inner longitudinal groove 29 which opens towards the front longitudinal opening O.

Thus, the front longitudinal opening O is delimited longitudinally by two inner longitudinal grooves 29 and opens towards the front of the mounting frame 1.

These two inner longitudinal grooves 29 are used for the installation of the veneer 2.

In practice, as shown in figures 1 and 2, the trim panel 2 is in the form of a rectangular flat frame having a rectangular central opening 2A of a size almost equal to the added size of the juxtaposed cover plate 3 and trapdoor 4 (see figure 1). Along the two parallel longitudinal edges of the central opening 2A, the finishing panel 2 carries on its rear surface two gibs 2B which extend perpendicularly to said rear surface and are adapted to snap into said inner longitudinal grooves 29 of the longitudinal walls 20 so that the rectangular central opening 2A coincides with said front longitudinal opening O of the mounting frame 1 (see fig. 17), the rear surface of said finishing panel 2 covering the front longitudinal edges 101A of the fixed supports 100 of the mounting device 10 and the front longitudinal edges 21A of the two longitudinal walls 20.

The veneer 2 thus mounted has a portion extending outside beyond the boundary (see fig. 17) to abut against the front surface of a receiving wall (not shown) around the opening of the wall.

The cover plate 3 is a molded plate made of, for example, aluminum. Here, it has a rectangular shape adapted to the shape of the front longitudinal opening O of the mounting frame 1 to be plugged. The cover plate 3 comprises on its rear surface a sliding track in which a small plate 5 suitable for mounting said cover plate 3 on the cover element 300 of the mounting device 10 is inserted.

More specifically, two small plates 5 inserted into both ends of the cover plate 3 are provided, each small plate 5 being used to mount the cover plate 3 on the cover member 300 of the corresponding mounting device 10.

As shown in fig. 2, the trapdoor 4 is in the form of a profiled strip.

It is also made of aluminium, for example.

It comprises, along its front longitudinal edge 4A, a recess in which two axes Y projecting from the edge of the end of said trapdoor 4 are inserted. The rear longitudinal edge 4B of the trapdoor 4 carries a drive pin 4D that projects beyond the end edge 4C (the one on the right in fig. 2).

The axis Y is snapped into a notch 102 provided on the front longitudinal edge 101A of the fixed support 100 of the two mounting devices 10, in the vicinity of the front lateral edge 101C of said fixed support 100.

The trapdoor 4 is thus pivotally mounted on the fixed support 100 by its front longitudinal edge 4A about said axis Y between a closed position (see fig. 1) and an open position (see fig. 17). As shown in fig. 17, in the open position the trapdoor 4 clears the passage for the power supply cable C of the plug F inserted in the equipment of the multi-equipment enclosure 6 connected to the mounting part 200 of the mounting device 10 towards the inside of the mounting frame 1.

The front longitudinal edge 4A of the trapdoor 4 is in close proximity to the longitudinal edge of the rectangular central opening of the trim panel 2, and when the trapdoor 4 is in the closed position-as shown in fig. 1-the two end edges 4C of this trapdoor 4 are in close proximity to a portion of the transverse edges of the rectangular central opening of said trim panel 2, and the rear longitudinal edge 4B of the trapdoor 4 is in close proximity to the front longitudinal edge of the cover panel 3 in the closed position.

When the trapdoor 4 is mounted on the fixed support 100, the driving pin 4D extends from the inside of the mounting frame 1, passing through the guiding aperture 107 provided on the fixed support 100 of the respective mounting device 10 (the one on the right in fig. 1 and 2). The guide slits 107 extend along an arc. In the vicinity of said guide aperture 107, the drive pin 4D abuts against the end extension 802 of the wire spring 800 wound on the peg 105 carried by the outer surface 100A of said fixed support 100. The other end of the wire spring 800 engages behind a retaining stop 106, which is also provided on the outer surface 100A of the fixed bearing 100. Accordingly, the wire spring 800 is mounted on the outer surface 100A of the fixed bearing 100 under stress.

The wire spring 800 is particularly shown in fig. 4.

The end extension wire 802 of the wire spring 800 continuously pushes the driving pin 4D of the trapdoor 4 towards the front of the mounting frame 1 to continuously return the trapdoor 4 to the closed position in the plane of the rectangular central opening of the trim panel 2, as shown in fig. 1.

In order to open the trapdoor 4, it is only necessary to press it to pivot it towards the inside of the mounting frame 1. The drive pin 4D transitions into the guide aperture 107 of the fixed support 100, guiding the pivoting movement of the trapdoor 4 by pushing the end extension 802 (see fig. 17) of the wire spring 800, whereby the wire spring 800 stores torsional energy.

Once the pressure exerted on the trapdoor 4 is released, the wire spring 800 releases its stored energy and its end extension wire 802 pushes the driving pin 4D of the trapdoor 4 towards the front of the mounting frame 1. The drive pin 4D transitions into the guide aperture 107 of the fixed support 100 and automatically drives the trapdoor 4 to pivot from the open position (fig. 17) to the closed position (fig. 1).

The salient features that are common to both mounting devices 10 of the mounting frame 1 will now be explained in detail.

In fact, the two mounting devices 10 are substantially identical, with the difference that, on the one hand, the drive of the trapdoor 4 just described is only on the right-hand mounting device, and, on the other hand, as will be explained in detail later, the fixed support of the right-hand mounting device comprises a cam-like track (path, road) concavely provided on its inner surface, the edge of which is serrated over the entire length, whereas the cam-like track concavely provided on the inner surface of the fixed support of the left-hand mounting device is serrated over only a part of its edge.

The right-hand mounting device 10 is shown in more detail in fig. 4 and 5, and the left-hand mounting device 10 is shown in more detail in fig. 6.

In the following description, for the sake of convenience, reference is made to only one mounting device, but it is clear that reference is made to two mounting devices at the same time.

The mounting device 10 is a system distinct from the multiple equipment cabinet 6.

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

In practice, the cover element 300 is a distinct component from the multiple equipment case 6, on which said cover 3 belonging to the frame 1 is mounted by means of the small plate 5.

It is worth noting that the mounting device 10 comprises a mounting member 200 distinct from said cover element 300, which is pivotally mounted on the fixed support 100 and is adapted to receive the end piece 70 of said multiple equipment cabinet 6.

It is also worth noting that in the mounting device 10, the driving means 321, 221 provided on the cover element 300 and on the mounting part 200 cooperate with each other such that, only during a partial overturning movement of the cover element 300, the cover element 300 drives the mounting part 200 to overturn from the closed position to the open position, so as to be able to access (approach) the front face of the multiple equipment cabinet 6.

Preferably, the fixed support 100, the cover element 300 and the mounting member 200 are all integral components made of a rigid plastic material.

In fig. 1 and 5, the assembled mounting device 10 is shown in a use position.

As explained above, the fixed bearing 100 takes the form of a cheek delimited by a front longitudinal edge 101A, a rear longitudinal edge 101B, a front lateral edge 101C and a rear lateral edge 101D. The fixed bearing 100 includes an inner surface 100B facing the cover member 300 and the mounting member 200, and an outer surface 100A opposite to the inner surface 100B.

More specifically, as shown in fig. 7 and 8, the cover member 300 includes a support plate 310 that is generally rectangular and has parallel and opposing front and

rear surfaces

310A and 310B.

In use, the front and

rear surfaces

310A, 310B of the support plate 310 of the cover element 300 extend in a plane perpendicular to the plane of the inner surface 100B of the support 100.

The front surface 310A of the support plate 310 is intended to receive the mounting platelet 5 of the cover plate 3. It carries projecting tongues 312, two of which are arranged along a longitudinal edge 311A of the support plate 310 and the third of which is placed in the vicinity of the opposite other longitudinal edge 311B of said support plate 310. These tongues 312 can be snapped into corresponding openings 5A of the mounting platelet 5 of the cover plate 3 to connect the cover plate 3 with said support plate 310. Two notches 313 are also provided on the longitudinal edge 311A of the support plate 310. These notches 313 are intended to receive two studs 5B (see fig. 17) carried by the rear surface of the small plate 5, so that the cover plate 3 is centred on said support plate 310 of the cover element 300.

As shown in fig. 7 and 8, the cover member 300 includes a mounting wall 320 extending perpendicularly from the rear surface 310B of the support plate 310. The mounting wall 320 includes an outer surface 320A facing the inner surface 100B of the fixed bearing 100 and an inner surface 320B parallel-opposed to the outer surface 320A. In use, the outer surface 320A and the inner surface 320B of the mounting wall 320 are substantially parallel to the inner surface 100B and the outer surface 100A of the fixed bearing 100.

Finally, at the corner of the support plate 310 opposite the mounting wall 320, the cover element 300 comprises a locking pin 327 extending perpendicularly to the rear surface 310B of the support plate 310, starting from the latter. The locking pin 327 includes two teeth 327A at its free end. It is intended to lock into an automatically locking latch 700 connected with the fixed support 100.

More specifically, the self-locking latch 700 is placed in a cavity 192 of the support 190 carried by the inner surface 100B of the fixed support 100 and is maintained in this cavity 192 by a maintenance tab (tab) 191.

The latch 700 comprises a main body 701 which is movable in the cassette and carries at its free end two locking tongues 702 which are hinged to the main body 701 by hinges. When the locking pin 327 of the cover element 300 exerts pressure on the main body 701 of the latch 700, which presses the main body 701 into its pocket, the locking tabs 702 come together against the teeth 327A of the locking pin 327 to maintain its connection with the main body 701. The depressed position of the body 701 in the magazine of the latch 700 is automatically locked by a cam-type system. To release the main body 701 of the latch 700, pressure need only be reapplied to the main body to unlock the cam system. The released body 701 is re-raised in the magazine of the latch 700. The tongue 702 is moved away from the box and opens to release the tooth 327A of the locking pin 327 of the cover element 300.

The mounting component 200 includes a square-contoured main plate 210 having an outer surface 210A facing the cover member 300 and an opposite inner surface 210B.

In use, the outer surface 210A and the inner surface 210B of the main plate 210 of the mounting part 200 are parallel to the outer surface 320A and the inner surface 320B of the mounting wall 320 of the cover member 300.

The inner surface 210B of the main plate 210 is bounded on three sides by three

walls

220A, 220B. These three

walls

220A, 220B extend perpendicular to the main plate 210. These

walls

220A, 220B define, together with the inner surface 210B of the main plate 210, a receiving cavity for the end piece 70 of the multiple-device case 6. The receiving volume includes a bottom formed by the inner surface of the wall 220B and an inlet opening that opens onto a fourth side 210C of the inner surface 210B of the main plate 210. As shown in fig. 17, the end piece 70 is inserted into the receiving cavity of the mounting part 200 such that the end side surface 6D of the multi-device case 6 is abutted against the inner surface 210B of the main board 210, and three sides of the end piece 70 are abutted against the inner surfaces of the

walls

220A, 220B of the mounting part 200. The main plate 210 is cut to form a tongue 213, which carries teeth 213A, which protrude from the inner surface 210B of the main plate 210. The teeth 213A are intended to hook the front flange of the end piece 70 of the multi-device case 6 inserted in the receiving cavity of the mounting part 200, to retain said end piece 70 in said receiving cavity. Once the mounting part 200 is mounted in the receiving cavity, the front face 6B of the multiple device case 6 faces the fourth side 210C of the main plate 210 of said mounting part 200.

The outer surface 210A of the main plate 210 of the mounting component 200 is visible in fig. 9 and 10. The outer surface 210A is bounded on one side by a reinforcing wall 215. It comprises a cylindrical tube 240 extending perpendicular to the outer surface 210A. The cylindrical pipe 240 is open at both ends thereof so that it opens to the inner surface 210B of the main plate 210 through the circular opening 212. The cylindrical conduit 240 engages a conduit barrel (chimney) 160 carried by the inner surface 100B of the fixed support 100 to pivotally mount the mounting member 200 on the fixed support 100. Thus, it can be appreciated that the inner diameter of the cylindrical conduit 240 is slightly larger than the outer diameter of the catheter hub 160 such that the outer surface of the catheter hub 160 forms a rotating guide surface for the cylindrical conduit 240. The guide tube barrel 160 includes internal threads and a locking screw V is inserted through the circular opening 212 and through the cylindrical conduit 240 of the mounting member 200 to be screwed into the guide tube barrel 160 to lock the mounting member 200 to the fixed support 100.

Advantageously, angular stop means 180, 230 are provided, which are adapted to place the mounting member 200 against the fixed support 100 in the closed and open position of the mounting member 200 and to limit the overturning path of the mounting member 200 independently of the overturning movement of the cover element 300.

The angular stop means 180, 230 are arranged to limit the overturning path of the mounting member 200 within an angular sector of about 65 degrees between its closed and open positions.

More specifically, as shown in fig. 9 and 10, the angle stopper means includes a groove 230 having an elongated closed contour curved along an arc of 65 degrees, provided on the outer surface 210A of the main plate 210 of the mounting part 200. The recess 230 is defined by a wall 231 carried by the outer surface 210A of the main plate 210 of the mounting component 200. The groove 230 includes two opposing rounded end edges 230A, 230B. The angular stop means also comprise a cylindrical peg 180 extending perpendicularly to the inner surface 100B of the fixed support 100, engaged in said groove 230, adapted to abut against each of the two

end edges

230A, 230B of said groove 230, and adapted to transition from one end edge 230A to the other end edge 230B of said groove 230 by sliding along the longitudinal edge 231A of said groove 230 during the overturning of said mounting component 200.

Said cylindrical abutment 180 of the fixed bearing 100 secures the closed position of said mounting member 200 against the end edge 230A of the recess 230 of the mounting member 200 (as shown in fig. 9 and 10), said cylindrical abutment 180 of the fixed bearing 100 secures the open position of said mounting member 200 against the other end edge 230B of the recess 230 of the mounting member 200.

Said primary elastic element 500, which causes the main overturning movement of the cover element 300, is a wire torsion spring with a diameter of 1.4 mm, with a relatively large section, wound around the cylindrical peg 170 carried by the inner surface 100B of the fixed support 100. One of the end extensions 502 of the wire spring 500 is maintained on the fixed support 100 by the hook 140A. When the cover element 300 is in the closed position and the cover element 300 is in most of the flip movement between its closed and open positions (as will be explained in more detail later with reference to fig. 11 to 16), the other end extension 501 of the wire spring 500 is inserted into a slot 360 (visible in fig. 7, 8 and 9) provided on the outer surface 320A of the mounting wall 320 of the cover element 300. When the end extension 501 of the wire spring 500 is constrained against the stop 140B carried by the inner surface 100B of the fixed support 100, said end extension 501 releases the cover element 300 after the end of the opening movement.

Preferably, an auxiliary elastic element 600 is provided, which is interposed under stress between said cover element 300 and said mounting member 200, to push said cover element 300 in the first opening phase, while maintaining said mounting member 200 in the closed position and against said fixed support 100 (the cylindrical studs 180 of the fixed support 100 abutting against the end edges 230A of the recesses 230 of the mounting member 200).

Preferably, as shown in fig. 7 and 8, the auxiliary elastic element 600 is a wire torsion spring and is wound around a peg 323 of an axis X3 projecting and extending from the outer surface 320A of the mounting wall 320 of the cover plate element 300, with its two

end extensions

601, 602 inserted from behind the retaining tabs 370 provided on said outer surface 320A, so that they are retained against said cover plate element 300. A part of one of the both end extension wires 601 of the wire spring 600 is hooked by a hook 270 attached to the outer surface 210A of the main plate 210 of the mounting part 200 (see fig. 9 and 10).

The cross-section of the auxiliary wire spring 600 is smaller than that of the main wire spring 500.

The pivotal mounting of the cover element 300 on the fixed support 100 is ensured by said damping means and by various guide elements which will be explained below.

Advantageously, on the one hand, said damping means comprise a cam track 110, which is concavely provided on the inner surface 100B of the fixed bearing 100 and is serrated over at least part of its length on one of its longitudinal edges, and on the other hand, said damping means comprise a gear 400, which is freely rotatably mounted on the outer surface 320A of the mounting wall 320 of the cover element 300, said gear 400 being adapted to be inserted into said cam track 110 so that its teeth cooperate with the serrations 112 of said cam track 110 during the tilting movement of said cover element 300.

As shown in fig. 4, 6, 7 and 8, the gear 400 is a pinion freely rotatably mounted on a shaft 412 of a support 410, said support 410 being provided with two snap tabs 411. The bearing 410 is inserted into the housing 340 provided on the outer surface 320A of the mounting wall 320 of the cover element 300 so that its catch tab 411 hooks the edge of the opening provided at the bottom of said housing 340. So mounted, the gear 400 is placed parallel to the outer surface 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 fig. 1) so that it does not open on the outer surface 100A of the fixed bearing 100.

Fig. 4 shows the cam track 110 of the fixed bearing 100 of the right-hand mounting device 10, which is serrated over the entire length of one of the longitudinal edges. Fig. 6 shows the cam track 110 of the fixed support 100 of the left mounting device 10, which is serrated over only a portion of the length of one of the longitudinal edges.

According to an advantageous particular feature, the cam-like track 110 comprises four portions corresponding to the four phases of the turning movement of the cover element 300, i.e. said cam-like track 110 comprises, from the front end 110A to the rear end 110F, a first portion 110B in the shape of a circular arc, a second portion 110C in the shape of an oblique straight line, a third portion 110D in the shape of a circular arc and a fourth portion 110E in the shape of a vertical straight line.

The linear second portion 110C of the cam track 110 is slightly inclined rearward from the front of the fixed bolster 100.

The first portion 110B of the cam track 110 is adapted to control the flipping motion of the cover member 300 over an angle of about 25 degrees, the second portion 110C of the cam track 110 is adapted to translate the cover member 300 out of alignment by a distance of about 3 mm, the third portion 110D of the cam track 110 is adapted to control the flipping motion of the cover member 300 over an angle of about 65 degrees, and the fourth portion 110E of the cam track 110 is adapted to control the flipping motion of the cover member 300 over an angle of about 12 degrees.

On the fixed bearing 100 of the left side mounting device 10 shown in fig. 6, the first portion 110B of the cam track 110 has a smooth longitudinal edge that is not serrated.

The integral cutting of the longitudinal edges of the cam tracks 110 of the fixed supports 100 of the two mounting devices 10 of the mounting frame 1 into a saw-toothed shape allows to adapt the force required for the first automatic opening phase of the cover 3 to the force of the spring.

In addition, a guide of the cover element 300 is provided.

The guide means comprises a main groove 120 in the fixed support 100 and comprises a guide finger 322 protrudingly provided on an outer surface 320A of the mounting wall 320 of said cover element 300 and slidably inserted in the main groove 120.

The main groove 120 is a slit that opens to the inner surface 100B and the outer surface 100A of the fixed bearing 100. It extends alongside the cam track 110 along a path parallel to the above-mentioned path of the cam track 110. Accordingly, the guide fingers 322 are on the outer surface 320A of the mounting wall 320 of the cover member 300, just beside the gear 400. It extends perpendicularly to said outer surface 320A along an axis X2 parallel to axis X3. The slot 360 in which the end extension 501 of the wire spring 500 is inserted is located behind the bottom from which the guide finger 322 begins to extend (see fig. 7, 8 and 9).

Therefore, like the cam rail 110, the main groove 120 includes four portions corresponding to four stages of the flip movement of the cover member 300, i.e., the main groove 120 includes a circular arc-shaped first portion 120B, an inclined linear second portion 120C, a circular arc-shaped third portion 120D, and a vertical linear fourth portion 120E from the front end 120A to the rear end 120F.

The second portion 120C of the main groove 120 is slightly inclined rearward from the front of the fixed bearing 100.

The first portion 120B of the main slot 120 is adapted to guide the flap member 300 for a flipping motion over an angle of about 25 degrees, the second portion 120C of the main slot 120 is adapted to translate the flap member 300 out of alignment by a distance of about 3 mm, the third portion 120D of the main slot 120 is adapted to guide the flap member 300 for a flipping motion over an angle of about 65 degrees, and the fourth portion 120E of the main slot 120 is adapted to guide the flap member 300 for a flipping motion over an angle of about 12 degrees.

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

Said auxiliary guide means comprise, on the outer surface 320A of the mounting wall 320 of the cover element 300, a cylindrical peg 323 extending along the axis X3, on which the auxiliary wire spring 600 is wound, which is inserted in a hollow elbow slot 130 formed on the inner surface 100B of the fixed support 100. The elbow slot 130 extends around a guide tube barrel 160 on which the mounting member 200 is rotatably mounted. The elbow-shaped slot is blind (not pierced) and is closed by a bottom 131 on the side of the outer surface 100A of the fixed support 100. The auxiliary guide means also comprise an elbow-shaped wall 150, carried by the inner surface 100B of the fixed support 100 and forming a ramp, on which a complementary ramp 350 carried by the cover element 300 slides along the rear edge 321B of the mounting wall 320. The elbow wall 150 of the fixed bearing 100 extends along the slot between the cylindrical post 170 and the slot 130. The complementary ramp 350 is formed by an elbow-shaped wall that extends in width perpendicular to the inner surface 320B of the mounting wall 320. The auxiliary guide means provided between the cover member 300 and the mounting wall 320 comprises a cylindrical finger 324 extending along the axis X3 on the inner surface 320B of the mounting wall 320 of the cover member 300. The cylindrical finger 324 and the cylindrical peg 323 extend opposite each other along the same axis X3 (see fig. 7). The cylindrical fingers 324 are inserted into the elongated apertures 214 that pass through the main plate 210 of the mounting member 200.

Said driving means interposed between the cover element 300 and the mounting part 200 comprise a driving finger 321, the projection of which is provided on the inner surface 320B of the mounting wall 320 of the cover element 300 and is inserted into the aperture 221 provided in said mounting part 200. The slot 221 is L-shaped and includes a first portion 221A and a second portion 221B connected by a bend. The second portion 221B includes a bottomed portion extending beyond the main plate 210. The drive finger 321 is arranged at one end of a pin extending perpendicularly to said inner surface 320B along an axis X1 starting from said inner surface 320B.

The guide means of the cover member 300 is distinguished from the driving means and the buffering means, and in association with the driving means and the buffering means, it is possible to allow the cover member 300 and the mounting member 200 to perform a smooth flip motion without being caught.

With reference to fig. 11 to 16, the opening and closing movement of the cover plate 3 of the mounting frame 1 connected to the cover plate elements 300 of the two mounting devices 10 will now be described, while the opening and closing movement of the mounting part 200 associated therewith will be described.

These movements will be broken down into different phases, but of course these phases will be continued one after the other, not intermittently, nor stuck.

Fig. 11 shows the left-hand mounting device 10 of the mounting frame 1 closed by the cover plate 3 from the inside and from the outside (as shown in fig. 1). The cover element 300 supporting the cover plate 3 extends laterally in the closed position, so that the cover plate 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 member 200 in the closed position has a receiving cavity with an inlet opening facing rearwardly and inclined at 25 degrees to a vertical line visualized by the axis V. In this position, the auxiliary wire spring 600 is connected to the cover member 300 and the mounting member 200 under stress. The main wire spring 500 is also connected to the cover member 300 and the fixed bearing 100 under stress. The driving finger 321 of the cover member 300 is restricted near the end of the first portion 221A of the slit 221 of the mounting part 200. The cylindrical peg 180 (not visible) of the fixed bearing 100 abuts the end edge 230A of the groove 230 of the mounting member 200. Finally, the guide fingers 322 of the cover element 300 are positioned near the front edge 120A of the main slot 120 of the fixed bearing 100, and the gear 400 (not visible) is positioned near the front edge 110A of the cam track 110.

The user briefly presses the cover plate 3 to press the locking pin 327 and the main body 701 of the latch member 700 into the magazine of the latch member 700.

This has the effect of releasing the locking pin 327 of the locking tab 702 from the latch 700, as shown in fig. 12. The auxiliary wire spring 600 immediately pushes the cover member 300 to open the cover 3 by an angle a equal to 25 degrees. The gear 400 of the cover element 300 rolls in the first portion 110B of the cam track 110 of the fixed bearing 100 and at the same time cooperates with the saw teeth 112 to control the overturning of said cover 300 and thus of the cover 3. The guide finger 322 of the cover member 300 traverses the entire first portion 120B of the main groove 120 of the fixed bearing 100. In the first opening phase of the cover 3, the mounting part 200 is immobilized, because the drive finger 321 of the cover element 300, which transitions into the aperture 221 of the mounting part 200, does not press the edge of the aperture 221. In addition, the auxiliary wire spring 600 maintains the mounting member 200 against the fixed support 100. More specifically, it maintains the end edge 230A of the groove 230 of the mounting member 200 against the cylindrical peg 180 of the fixed bearing 100.

Thus, the primary wire spring 500 takes over the secondary wire spring 600 and pushes the cover member 300 to be turned toward the inside of the mounting frame 1.

In so doing, as shown in fig. 13, the guide fingers 322 of the cover member 300 traverse the entire linear second portion 120C of the main slot 120, causing the cover member 300 (and thus the cover 3) to translate rearwardly by a few millimeters, and the drive fingers 321 to abut against the edges of the apertures 221 of the mounting member 200. The gear 400 of the cover member 300 also rolls in the linear second portion 110C of the cam track 110 and at the same time cooperates with the serrations 112 to control the movement of the cover member 300. Thus, the cover member 300 causes the mounting part 200 to be turned upside down.

As shown in fig. 14 and 15, the cover element 300 supporting the cover 3 and the mounting part 200 supporting one end of the multiple equipment cabinet 6 (not shown in these figures for greater clarity) are jointly turned over an angle of 65 degrees under the action of the stored energy released by the wire spring 500 and the relaxing thrust. During the opening phase, the guide fingers 322 of the cover element 300 transition into the third section 120D of the main channel 120 of the fixed bearing 100. The gear 400 of the cover element 300 rolls in the third portion 110D of the cam track 110 of the fixed bearing 100 and at the same time cooperates with said saw teeth 112. The drive finger 321 transitions slidingly along the second portion 221B of the aperture 221 of the mounting member 200 against the edge of the aperture 221. The cylindrical fingers 324 of the cover element 300 transition into the apertures 214 of the mounting part 200.

After the end of the opening phase, the cover element 300 is turned with the cover plate 3 into the interior of the mounting frame 1, at about 90 degrees from the closed position, as shown in fig. 15. They clear the front longitudinal opening O of the mounting frame 1. The mounting member 200 is in the open position against the fixed support 100. In fact, in the open position, the other end edge 230B of the groove 230 of said mounting member 200 abuts against the cylindrical peg 180 of the fixed bearing 100. Therefore, the mounting part 200 can no longer be turned over. In the open position of the mounting part 200, the inlet opening in the receiving cavity of the mounting part 200 is positioned laterally (that is to say at 90 degrees with respect to the vertical V) and faces the front longitudinal opening O of the mounting frame 1. The front face 6B of the multiple equipment cabinet 6 (not shown here) facing the access opening is thus facing the front longitudinal opening O of the mounting frame 1 and the user can access the equipment of the cabinet.

It is important to note that after the end of the opening phase, the primary wire spring 500 is relaxed to the maximum and its end extension wire 501 is blocked against the stop 140B of the fixed bearing 100. It is thus no longer associated with the slot 360 of the cover element 300. The end extension 601 of the secondary wire spring 600 is also no longer associated with the hook 270 of the mounting member 200 (as shown in fig. 15, the individual hooks 270 can be seen in the window in the main plate 210 of the mounting member 200).

As shown in fig. 16, the cover element 300 (and the cover plate 3 supported thereby) is no longer tensioned by the wire springs 500, 600 and continues to turn inside the mounting frame 1 under its own weight to form an opening inclination angle B of about 12 degrees towards the rear with respect to the vertical V. The mounting member 200 remains stationary in the open position. In the final opening phase, the guide fingers 322 of the cover element 300 transition into the rectilinear fourth portion 120E up to the rear edge 120F of the main groove 120 of the fixed bearing 100. The gear 400 of the cover member 300 rolls in the fourth portion 110E of the cam track 110 of the fixed bearing 100 up to the rear edge 110F and cooperates with said serrations 112. The drive finger 321 transitions slidingly along the second portion 221B against the edge of the aperture 221 of the mounting member 200 up to the end of said aperture 221. The cylindrical fingers 324 of the cover element 300 pass through the apertures 214 of the mounting element 200 to the ends of said apertures 214.

The cover 3 is fully open. Its opening inclination facilitates access to the interior of the mounting frame 1 and thus to the multiple equipment cabinet 6 connected to said frame.

It should be noted that in this position, the

cylindrical fingers

321, 324 are in a lower position in the

respective apertures

221, 214, thereby facilitating locking of the multi-device case so that the multi-device case remains stationary when a plug is inserted or removed.

During the entire tilting movement of the cover element 300 described above, the cylindrical peg 323 of the cover element 300 transitions in the elbow slot 130 of the fixed bearing 100 and the complementary ramp 350 of the cover element 300 slides along the ramp 150 of the fixed bearing 100.

In order to close the cover plate 3 from its open position, it is merely necessary to manually grasp the end of the cover plate 3 projecting out of the front longitudinal opening O of the mounting frame 1 (see fig. 16) and pull it to the trapdoor 4 until the locking pin 327 of the cover plate element 300 is locked in the latch 700. Thus, the cover member 300 and the mounting part 200 are reversed toward the original closed position.

During reverse flipping, the slot 360 of the cover member 300 catches the end of the wire spring 500 as it extends the wire 501 past it, placing the wire spring 500 back under tension. The hook 270 of the mounting member 200 catches the auxiliary wire spring 600 as it is extended 601 past the end of the wire spring so that the wire spring 600 is also placed under tension again.

The guide fingers 322 of the cover member 300 are re-raised into the main grooves 120 of the fixed bearing 100. The gear 400 of the cover element 300 rolls in the cam track 110 of the fixed bearing 100 and cooperates with said saw teeth 112. Drive finger 321 transitions along aperture 221 of mounting member 200.

It will be noted that the guide fingers 322 pass through the rectilinear second portion 120C of the main slot 120 and the gear 400 passes through the rectilinear second portion 110C of the cam track 110 simultaneously, so that the cover element 300 is slightly staggered towards the front to lift the drive fingers 321 against the edges of the apertures 221 of the mounting member 200. The mounting member 200 reaches its closed position (see fig. 12) and the cover element 300, which is no longer associated with the mounting member 200, alone continues to flip towards the closed position shown in fig. 11.

The invention is not limited to the embodiments described and shown in the different figures, but a person skilled in the art will understand how to make any modifications according to the spirit of the invention.
