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

Description

Mounting device for a multi-device box, mounting frame comprising such a mounting device, and multi-device comprising such a mounting frame and a multi-device box

Technical Field

The present invention relates generally to the embedding of a multi-device in an opening in a wall of an office furniture item.

More particularly, the invention relates to a mounting device for mounting a multi-device box in an opening of a receiving wall, such mounting device comprising a cover element pivotally mounted on a fixed support, the automatic opening device of the cover element comprising, on the one hand, a main elastic element acting on the cover element to cause a tilting movement from a closed position to an open position, and, on the other hand, a damping device acting between the cover element and the fixed support during the tilting movement to control and damp the course of the cover element.

Background

A device of the above-mentioned type is known in particular from documents WO2008154021 and US9395770, in which the cover element is connected to the multi-device box to form a unitary assembly pivotally mounted on the fixed support. According to the document, the elastic element acts on the monolithic assembly to cause it to flip from the closed position to the open position, and the damping means act between the monolithic assembly and said fixed support during the flip movement.

Disclosure of Invention

In contrast to the prior art described above, the invention proposes an improved device in which the element supporting the multi-device housing and the cover element are two distinct (different, distinct, distinguishable) parts, the tilting movements of which are coordinated.

More specifically, the invention proposes a mounting arrangement wherein a cover element is a component distinct from a multi-device case, wherein a mounting component distinct from the cover element is provided, which is pivotally mounted on a fixed support and adapted to receive a portion of the multi-device case, wherein drive means are provided on the cover element and on the mounting component, which drive means cooperate with each other such that during only a partial tilting movement of the cover element drives the mounting component to tilt (swing) from a closed position to an open position, thereby allowing access to the front face of the multi-device case.

Advantageously, therefore, by means of the invention, the cover element can be opened at an angle greater than the opening angle of the multi-device case, thereby facilitating access to the front face of said case. In addition, in the partially open phase, the damping means act only on the cover elements, which have a mass less than that of the tank, they are easier to use, more efficient and more durable, since they are subjected 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 combination with each other in a technically possible manner:

-providing an angular stop means adapted to place the mounting member against the fixed support in its closed and open position and to limit the tilting stroke of the mounting member independently of the tilting movement of the cover element;

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

the angular stop means comprise, on the one hand, 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, a cylindrical abutment (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;

-providing an auxiliary elastic element 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 on a post extending convexly from the outer surface of the cover element, the two end extensions of which are maintained against said cover element, a portion of one of said two end extensions of said wire spring being hooked by a hook attached to said mounting part;

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

-the cam track is formed with serrations over the entire length of one of its longitudinal edges;

the cam track comprises four portions corresponding to the four phases of the tilting movement of the cover element, i.e. the cam track comprises, from the front end to the rear end, a first portion of circular arc shape, a second portion of inclined rectilinear shape, a third portion of circular arc shape and a fourth portion of vertical rectilinear shape;

-a first portion of the cam track is adapted to control the tilting movement of the cover element over an angle of about 25 degrees, a second portion of the cam track is adapted to shift the cover element translationally by a distance of about 3 mm, a third portion of the cam track is adapted to control the tilting movement of the cover element over an angle of about 65 degrees, and a fourth portion of the cam track is adapted to control the tilting movement of the cover element over an angle of about 12 degrees;

the driving means comprise a driving finger (finger-like driving member) arranged convexly on the inner surface of the cover element and adapted to be inserted into a slot provided in the mounting part;

-providing a cover element guide means, which is distinct from and associated with the drive means and the buffer means, such that the cover element and the mounting part perform a smooth tilting movement without jamming;

The guide means comprise a main groove in the fixed support and comprise guide fingers which are arranged convexly on the outer surface of the cover element and which are inserted slidingly into the main groove;

the main slot comprises four portions corresponding to the four phases of the tilting movement of the cover element, i.e. the main slot comprises, from front end to rear end, a first portion of circular arc shape, a second portion of inclined rectilinear shape, a third portion of circular arc shape and a fourth portion of vertical rectilinear shape;

-a first portion of the main slot is adapted to guide the tilting movement of the cover element over an angle of about 25 degrees, a second portion of the main slot is adapted to shift the cover element translationally by a distance of about 3 mm, a third portion of the main slot is adapted to guide the tilting movement of the cover element over an angle of about 65 degrees, and a fourth portion of the main slot is adapted to guide the tilting movement of the cover element over an angle of about 12 degrees.

The invention also proposes a mounting frame intended to be inserted into an opening of a receiving wall, comprising two parallel longitudinal walls maintained at a predetermined fixed distance from each other by means of two fixed supports of the mounting device according to the invention mounted at each end of said longitudinal walls; the mounting frame comprises a cover plate connected to the cover plate element of the mounting device to close a substantial portion of the front longitudinal opening of the frame; the mounting frame comprises a trapdoor which is mounted in a reversible manner 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-device arrangement intended to be mounted in an opening of a receiving wall, comprising a mounting frame as described above and a multi-device housing mounted in a mounting part of the mounting arrangement according to the invention.

Detailed Description

In the following description, the term "front" conventionally refers to the side of the element that faces the user when in the in-use position on the wall, and the term "rear" refers to the opposite side of the element, i.e. the side that faces the interior of the wall.

In fig. 1 and 17, a multi-device arrangement according to the invention is shown in a closed configuration and an open configuration, which multi-device arrangement is 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 in a wall of office furniture such as a workbench, reception counter or even any locker.

The multi-device arrangement advantageously comprises a mounting frame 1, the whole of which is shown in fig. 2, and a multi-device box 6, which is shown more particularly in fig. 3, which is connected into a mounting arrangement 10 of the mounting frame 1.

The multi-device case 6 and each mounting means 10 are systems that are distinct from each other, so that they have no common components in a sense, but as will be explained later, they have portions that cooperate with each other such that the mounting means 10 ensure a controlled tipping of said multi-device case 6 between a closed position and an open position.

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

As shown in fig. 3, the multi-equipment cabinet 6, commonly called an equipment box, has a rectangular parallelepiped shape with two parallel longitudinal walls 60 maintained at a predetermined fixed distance from each other by a cover 80 snapped onto an arrangement forming the rear portion of the support of said longitudinal walls 60 and end pieces (hoops, kits) 70 connected to opposite ends of the multi-equipment cabinet 6 and fixed to the longitudinal walls 60 by means of screws V2.

The above-described various elements constituting the structure of the multi-device case 6 are each a single member (single piece) made of a molded plastic material filled with a light metal material such as glass fiber or aluminum.

Thus, the multi-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 case 6 is formed by the front surface of a panel (garnish) 50 of devices 51, 52, 53, and 54 connected to the multi-device case 6. The panels 50 are arranged in a continuous butt-joint manner such that they close the entire front longitudinal opening of the multi-device box 6 defined between the longitudinal folds with respect to said longitudinal walls 60.

The front flange 71 of each end piece 70 extends in an extension of the front surface 6B of the multi-device case 6.

Finally, the rear surface 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. The connector 90 is intended to be connected to a local power supply network. In a variant, the connector may be replaced by the 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 includes two parallel longitudinal walls 20 maintained at a predetermined fixed distance from each other by two fixed supports 100 of the mounting device 10 mounted at each end of the longitudinal walls 20, a cover 3 distinguished from the multi-equipment box 6, and a cover element 300 connected to the mounting device 10 to close a large portion of a front longitudinal opening O of the mounting frame 1, a trapdoor 4 swingably mounted on the fixed supports 100 of the mounting device 10 to close a portion of the front longitudinal opening O not closed by the cover 3 (see fig. 17), and a veneer panel in the form of a frame and connected around the cover 3 and the trapdoor 4 (see fig. 17).

Preferably, the longitudinal wall 20 is an extruded aluminium 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 groove 26C with a circular bottom, which is directed rearwards and open at each end, which extends along the outer surface 20A of the longitudinal wall 20 over the entire length of said longitudinal wall 20. The opposite inner surface of each first groove 26C is fluted.

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, said inner surfaces together defining a second groove 23C having a cylindrical profile, which second groove 23C is open at both ends and comprises a front longitudinal opening facing 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, 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 support 100 comprises an outer surface 100A facing the outside of the mounting frame 1 and an inner surface 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 includes two recesses 103 along the front lateral edge 101C and the rear lateral edge 101D. Each recess 103 opens onto the front lateral edge 101C or the rear lateral edge 101D of the fixed support 100 and is delimited on three sides by a flange 103A. Each fixed support 100 comprises a through aperture 104 which opens on one side into the bottom of the recess 103. Each recess 103 is provided with two apertures 104, one of which apertures 104 is located near the front longitudinal edge 101A of the fixed support 100 and the other aperture 104 is located near 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 defining said recess 103, such that the open ends of the first and second grooves 26C, 23C are opposite 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 screwed into said first and second grooves 26C, 23C through said aperture 104 (see fig. 1 and 2).

The longitudinal wall 20 and the fixed support 100 of the mounting device 10 are thus assembled to define an internal space suitable for receiving the multi-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, the multi-device box 6 is mounted in the mounting part 200 of the mounting device 10, and, on the other hand, the front surface 6B of the box is accessible once the box is mounted and connected to the local power supply network, in order to connect the plug F to the different devices of the box 6.

At the front, each longitudinal wall 20 is equipped with a clip strip.

More specifically, as shown in fig. 17, each clip strip here 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 is located inside the mounting frame 1, moving at a distance from the free front edge 21A of each longitudinal wall 20.

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

Thus, the front longitudinal opening O is longitudinally delimited by the 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 mounting of the veneer 2.

In fact, as shown in figures 1 and 2, the veneer panel 2 is in the form of a rectangular flat frame having a rectangular central opening 2A of a size almost equal to the sum of the dimensions of the juxtaposed cover plate 3 and trapdoor 4 (see figure 1). Along two parallel longitudinal edges of the central opening 2A, the trim panel 2 carries on its rear surface two clip strips 2B extending perpendicularly to said rear surface and 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 trim panel 2 covering the front longitudinal edges 101A of the fixed support 100 of the mounting device 10 and the front longitudinal edges 21A of the two longitudinal walls 20.

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

The cover plate 3 is a molded plate made of aluminum, for example. 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 rail into which the small plate 5, which is adapted to mount said cover plate 3 on the cover plate 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 for mounting the cover plate 3 on the cover plate element 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 aluminum, for example.

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

The axis Y snaps into a recess 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 about said axis Y by its front longitudinal edge 4A 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 of the power supply cable C for the plug F inserted into the equipment of the multi-equipment box 6 connected to the mounting part 200 of the mounting device 10, toward the inside of the mounting frame 1.

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

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

Wire spring 800 is shown in particular in fig. 4.

The end extension wire 802 of the wire spring 800 continues to push the drive 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 driving pin 4D transitions into the guide slot 107 of the fixed support 100, guiding the pivoting movement of the trapdoor 4 by pushing the end extension wire 802 (see fig. 17) of the wire spring 800, whereby the wire spring 800 stores torsion energy.

Once the pressure applied to the trapdoor 4 is released, the wire spring 800 releases its stored energy and its end extension wire 802 pushes the drive pin 4D of the trapdoor 4 towards the front of the mounting frame 1. The drive pin 4D transitions into the guide slot 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 common to both mounting devices 10 of the mounting frame 1 will now be described in detail.

In fact, the two mounting means 10 are substantially identical, with the difference that, on the one hand, the driving means of the trapdoor 4 just described are located only on the mounting means on the right side, and, on the other hand, as will be explained in detail later, the fixed support of the right side mounting means comprises cam tracks (paths, roads) concavely provided on its inner surface, the edges of which are formed with serrations over the whole length, while the cam tracks concavely provided on the inner surface of the fixed support of the left side mounting means are formed with serrations over only a part of the length of their edges.

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, only one mounting means is mentioned, but it is obvious that two mounting means are involved at the same time.

The mounting device 10 is a system that is distinguished from the multi-device enclosure 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 a damping device 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 component distinct from the multi-device case 6, on which the cover 3 belonging to the frame 1 is mounted by means of the small plate 5.

Notably, the mounting device 10 includes a mounting member 200 distinct from the cover element 300 pivotally mounted to the fixed support 100 and adapted to receive the end piece 70 of the multi-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 the mounting part 200 cooperate such that the cover element 300 drives the mounting part 200 to flip from the closed position to the open position only during a partial flip movement of the cover element 300, so that the front face of the multi-device case 6 can be contacted (accessed).

Preferably, the fixed support 100, the cover element 300 and the mounting part 200 are all integral parts 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 support 100 takes the form of a cheek defined by the front longitudinal edge 101A, the rear longitudinal edge 101B, the front lateral edge 101C and the rear lateral edge 101D. The fixed support 100 comprises an inner surface 100B facing the cover element 300 and the mounting part 200, and an outer surface 100A opposite said inner surface 100B.

More specifically, as shown in fig. 7 and 8, the cover element 300 includes a support plate 310 that is generally rectangular and has parallel and opposed front and rear surfaces 310A and 310B.

In use, the front surface 310A and the rear surface 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 plate 5 of the cover plate 3. It carries protruding 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 tabs 5 of the cover plate 3 to connect the cover plate 3 with said support plate 310. Two notches 313 are also provided in the longitudinal edge 311A of the support plate 310. These recesses 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 centered in said support plate 310 of the cover plate 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 support 100 and an inner surface 320B parallel to and opposite 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 support 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 this latter. The locking pin 327 includes two teeth 327A at its free end. It is intended to lock into an automatically locking latch 700 that is coupled to the fixed support 100.

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

The latch 700 comprises a body 701 movable in the box and carrying at its free ends two locking tongues 702 hinged to the body 701 by means of hinges. When the locking pin 327 of the cover element 300 exerts pressure on the body 701 of the latch 700, it presses this body 701 into its box, the locking tongue 702 coming together against the teeth 327A of the locking pin 327 to maintain its connection with the body 701. The depressed position of the body 701 in the case of the latch 700 is automatically locked by the cam system. To release the body 701 of the latch 700, pressure need only be reapplied to the body to unlock the cam system. The released body 701 is again raised in the box of the latch 700. Tongue 702 is disengaged from the box and opened to release the teeth 327A of locking pin 327 of cover element 300.

The mounting member 200 includes a square-contoured main plate 210 having an outer surface 210A facing the cover element 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 component 200 are parallel to the outer surface 320A and the inner surface 320B of the mounting wall 320 of the cover element 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, together with the inner surface 210B of the main plate 210, define a receiving pocket for the end piece 70 of the multi-device case 6. The receiving cavity includes a bottom formed by the inner surface of wall 220B and an inlet opening that opens onto the fourth side 210C of the inner surface 210B of main plate 210. As shown in fig. 17, the end piece 70 is inserted into the receiving pocket of the mounting member 200 such that the end side surface 6D of the multi-device case 6 abuts against the inner surface 210B of the main plate 210, and three sides of the end piece 70 abut against the inner surfaces of the walls 220A, 220B of the mounting member 200. The main plate 210 is cut to form tabs 213 that carry teeth 213A that 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 member 200 to hold said end piece 70 in said receiving cavity. Once the mounting component 200 is mounted in the receiving cavity, the front surface 6B of the multi-device case 6 faces the fourth side 210C of the motherboard 210 of the mounting component 200.

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

Advantageously, angular stop means 180, 230 are provided, 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 turning path of the mounting member 200 independently of the turning movement of the cover element 300.

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

More specifically, as shown in fig. 9 and 10, the angle stop means comprises a groove 230 provided on the outer surface 210A of the main plate 210 of the mounting member 200, the groove having an elongated closed profile curved along an arc of 65 degrees. The recess 230 is defined by a wall 231 carried by the outer surface 210A of the main board 210 of the mounting member 200. The recess 230 includes two opposed rounded end edges 230A, 230B. The angle stop means also comprise a cylindrical abutment 180 extending perpendicular to the inner surface 100B of the fixed support 100, engaged in said recess 230, adapted to abut against each of the two end edges 230A, 230B of said recess 230, and adapted to transition from one end edge 230A to the other end edge 230B of said recess 230 by sliding along the longitudinal edge 231A of the recess 230 during the turning of said mounting part 200.

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

The primary elastic element 500, which causes the primary tilting movement of the cover element 300, is a wire torsion spring of 1.4 mm diameter, having a relatively large cross section, wound around a cylindrical post 170 carried by the inner surface 100B of the fixed support 100. One of the end extensions 502 of the wire spring 500 is retained 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 a majority of the flip movement between its closed and open positions (explained in more detail later with reference to fig. 11 to 16), the other end extension wire 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 relaxes 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 part 200, to push said cover element 300 in a first opening phase, while maintaining said mounting part 200 in a closed position and against said fixed support 100 (the cylindrical abutment 180 of which fixed support 100 abuts against the end edge 230A of the recess 230 of the mounting part 200).

Better, as shown in fig. 7 and 8, the auxiliary elastic element 600 is a wire torsion spring and is wound around the post 323 of the shaft X3 extending convexly from the outer surface 320A of the mounting wall 320 of the cover element 300, with its two end extension wires 601, 602 inserted from behind the retaining tabs 370 provided on said outer surface 320A so that they are maintained against said cover element 300. A portion of one of the two 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 the damping device and by various guiding elements which will be described below.

Advantageously, on the one hand, the damping means comprise a cam track 110 concavely provided on the inner surface 100B of the fixed support 100 and having serrations formed on at least part of the length of one of its longitudinal edges, and on the other hand, the damping means comprise a gear 400 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 the teeth of the gear cooperate with the serrations 112 of said cam track 110 during the overturning movement of said cover element 300.

As shown in fig. 4, 6, 7 and 8, the gear 400 is a pinion mounted freely rotatably on a shaft 412 of a support 410, said support 410 being provided with two snap tabs 411. The support 410 is inserted into the cavity 340 provided on the outer surface 320A of the mounting wall 320 of the cover element 300, so that its snap tab 411 hooks over the opening edge provided at the bottom of said cavity 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 support 100.

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

According to an advantageous specific feature, the cam track 110 comprises four portions corresponding to the four phases of the tilting movement of the cover element 300, i.e. said cam 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 inclined 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 support 100.

The first portion 110B of the cam track 110 is adapted to control the tilting movement of the cover element 300 over an angle of about 25 degrees, the second portion 110C of the cam track 110 is adapted to shift the cover element 300 translationally by a distance of about 3 mm, the third portion 110D of the cam track 110 is adapted to control the tilting movement of the cover element 300 over an angle of about 65 degrees, and the fourth portion 110E of the cam track 110 is adapted to control the tilting movement of the cover element 300 over an angle of about 12 degrees.

On the fixed support 100 of the left mounting device 10 shown in fig. 6, the first portion 110B of the cam track 110 has smooth longitudinal edges that are not serrated.

Cutting the whole 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 in a zigzag manner allows the force required for the first automatic opening phase of the cover plate 3 to be adapted to the force of the springs.

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

The guide means comprises a main groove 120 in the fixed support 100 and comprises guide fingers 322 which are convexly provided on an outer surface 320A of the mounting wall 320 of said cover element 300 and slidingly inserted into the main groove 120.

The main groove 120 is a slit that opens into the inner surface 100B and the outer surface 100A of the fixed support 100. Which extends alongside the cam track 110 along a path parallel to the path of the cam track 110 described above. Accordingly, guide finger 322 is on outer surface 320A of mounting wall 320 of cover element 300, just beside gear 400. Which extends perpendicular to the outer surface 320A along an axis X2 parallel to the axis X3. The slot 360 into which the end extension wire 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).

Thus, like the cam rail 110, the main groove 120 includes four portions corresponding to four stages of the tilting movement of the cover member 300, that is, 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 backward from the front of the fixed support 100.

The first portion 120B of the main channel 120 is adapted to guide the flip movement of the cover element 300 over an angle of about 25 degrees, the second portion 120C of the main channel 120 is adapted to shift the cover element 300 translationally by a distance of about 3 millimeters, the third portion 120D of the main channel 120 is adapted to guide the flip movement of the cover element 300 over an angle of about 65 degrees, and the fourth portion 120E of the main channel 120 is adapted to guide the flip movement of the cover element 300 over an angle of about 12 degrees.

Auxiliary guides are also provided which are 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.

The auxiliary guide means comprise, on the outer surface 320A of the mounting wall 320 of the cover element 300, a cylindrical abutment 323 extending along the axis X3, around which the auxiliary wire spring 600 is wound, which cylindrical abutment is inserted into a hollow elbow slot 130 formed on the inner surface 100B of the fixed support 100. The elbow slot 130 extends around a catheter tube 160 to which the mounting member 200 is rotatably mounted. The elbow slot is blind (unpenetrated) and is closed by a bottom 131 on the side of the outer surface 100A of the fixed support 100. The auxiliary guide also comprises 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 support 100 extends along the slot between the cylindrical post 170 and the slot 130. The complementary ramp 350 is formed by an elbow wall extending in width perpendicular to the inner surface 320B of the mounting wall 320. The auxiliary guide means provided between the cover element 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 element 300. The cylindrical finger 324 and the cylindrical post 323 extend along the same axis X3 opposite each other (see fig. 7). The cylindrical fingers 324 are inserted into the elongated apertures 214 through the main plate 210 of the mounting member 200.

The driving means interposed between the cover element 300 and the mounting part 200 comprise driving fingers 321, which are provided protruding on the inner surface 320B of the mounting wall 320 of the cover element 300 and are inserted into apertures 221 provided in the mounting part 200. The slit 221 has an L-shape and includes a first portion 221A and a second portion 221B connected by a bent portion. The second portion 221B includes a portion with a bottom that extends beyond the motherboard 210. The driving finger 321 is provided at one end of a pin extending from the inner surface 320B perpendicularly to the inner surface 320B along the axis X1.

The guiding means of the cover element 300 are distinguished from the driving means and the damping means, which are associated with them, so that the cover element 300 and the mounting part 200 can be smoothly turned without jamming.

With reference to fig. 11 to 16, the description will now be made with respect to the opening and closing movement of the cover plate 3 of the mounting frame 1 connected to the cover plate element 300 of the two mounting devices 10, and at the same time with respect to the opening and closing movement of the mounting member 200 associated therewith.

These movements will be broken down into different phases, but of course these phases will be carried out continuously one after the other, without being interrupted and without jamming.

Fig. 11 shows the left-side mounting device 10 (as shown in fig. 1) of the mounting frame 1 enclosed by the cover plate 3 from the inside and the outside. The cover element 300 supporting the cover 3 extends transversely in the closed position such 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 member 200 in the closed position has a receiving cavity with its inlet opening facing rearward and inclined at 25 degrees relative to a vertical line represented by the axis V. In this position, the auxiliary wire spring 600 is connected to the cover element 300 and the mounting part 200 under stress. The main wire spring 500 is also connected under stress to said cover element 300 and the fixed support 100. The drive finger 321 of the cover element 300 is constrained near the end of the first portion 221A of the aperture 221 of the mounting member 200. The cylindrical post 180 (not visible) of the fixed support 100 abuts against the end edge 230A of the recess 230 of the mounting member 200. Finally, guide finger 322 of cover element 300 is positioned adjacent front edge 120A of main channel 120 of fixed support 100, and gear 400 (not visible) is positioned adjacent front edge 110A of cam track 110.

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

As shown in fig. 12, this operation has the effect of releasing the locking pin 327 of the locking tongue 702 from the latch 700. 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 support 100 and at the same time cooperates with the serrations 112 to control the overturning of said cover 300 and thus of the cover 3. Guide fingers 322 of cover element 300 traverse the entire first portion 120B of main channel 120 of fixed support 100. In the first opening phase of the cover plate 3, the mounting part 200 is not moved, since the drive fingers 321 of the cover plate element 300, which transition into the apertures 221 of the mounting part 200, do not press the edges of the apertures 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 recess 230 of the mounting member 200 against the cylindrical post 180 of the fixed support 100.

Thus, the main wire spring 500 takes over the auxiliary wire spring 600 and pushes the cover plate element 300 to turn it toward the inside of the mounting frame 1.

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

As shown in fig. 14 and 15, the cover element 300 supporting the cover 3 and the mounting member 200 supporting one end of the multi-device case 6 (not shown in these figures for clarity) are collectively flipped by an angle of 65 degrees under the action of the stored energy released by the wire spring 500 and the released thrust. During the opening phase, guide fingers 322 of cover plate element 300 transition into third portion 120D of main channel 120 of fixed support 100. The gear 400 of the cover element 300 rolls in the third portion 110D of the cam track 110 of the fixed support 100 and at the same time cooperates with said serrations 112. The drive finger 321 slides 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, as shown in fig. 15, the cover element 300 and the cover 3 are turned inside the mounting frame 1, at about 90 degrees from the closed position. They clear the front longitudinal opening O of the mounting frame 1. The mounting member 200 is in an open position against the stationary support 100. In fact, in the open position, the other end edge 230B of the recess 230 of the mounting member 200 abuts against the cylindrical abutment 180 of the fixed support 100. Thus, the mounting member 200 may not continue to flip. In the open position of the mounting part 200, the inlet opening in the receiving volume of the mounting part 200 is positioned laterally (that is to say at 90 degrees with respect to the perpendicular V) and faces the front longitudinal opening O of the mounting frame 1. The front surface 6B of the multi-device box 6 (not shown here) facing the inlet opening thus faces the front longitudinal opening O of the mounting frame 1 and the user can access the devices of the box.

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

As shown in fig. 16, the cover element 300 (and the cover 3 supported thereby) is no longer tensioned by the wire springs 500, 600 and continues to flip inwardly of the mounting frame 1 under its own weight to form an opening inclination angle B of about 12 degrees toward 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 finger 322 of the cover element 300 transitions into the rectilinear fourth portion 120E until the rear edge 120F of the main groove 120 of the fixed support 100. The gear 400 of the cover element 300 rolls in the fourth portion 110E of the cam track 110 of the fixed support 100 up to the rear edge 110F and cooperates with said serrations 112. The drive finger 321 slides along the second portion 221B against the edge of the aperture 221 of the mounting member 200 until the end of said aperture 221. The cylindrical fingers 324 of the cover element 300 transition in the slot 214 of the mounting element 200 up to the end of said slot 214.

The cover plate 3 is completely opened. Its opening inclination angle facilitates access to the interior of the mounting frame 1 and thus to the multi-device box 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 housing so that the multi-device housing remains stationary when a plug is inserted or removed.

During the entire tilting movement of the cover element 300 described above, the cylindrical studs 323 of the cover element 300 transition in the elbow slots 130 of the fixed support 100, and the complementary ramps 350 of the cover element 300 slide along the ramps 150 of the fixed support 100.

To close the cover plate 3 from its open position, it is only necessary to manually grasp the end of the cover plate 3 protruding from 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 element 300 and the mounting member 200 are reversed towards the original closed position.

During reverse rollover, the slot 360 of the cover member 300 catches the wire spring 500 as it passes over the end extension 501 of the wire spring 500, putting the wire spring 500 back under tension. The hooks 270 of the mounting member 200 grip the end extension 601 of the auxiliary wire spring 600 as it passes, so that the wire spring 600 is also re-tensioned.

Guide fingers 322 of cover element 300 are again raised into main channel 120 of fixed support 100. The gear 400 of the cover element 300 rolls in the cam track 110 of the fixed support 100 and cooperates with said serrations 112. The drive finger 321 transitions along the aperture 221 of the mounting member 200.

It is pointed out that the guide finger 322 passes from the rectilinear second portion 120C of the main slot 120, and the gear 400 passes from the rectilinear second portion 110C of the cam track 110 at the same time, so that the cover element 300 is slightly staggered towards the front to lift the driving finger 321 against the edge of the aperture 221 of the mounting part 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, a person skilled in the art appreciates how any modifications can be made according to the spirit of the invention.
