Description

DESCRIPTION

Furniture structure with lighting system

Technical field

The present invention refers to a furniture structure with a lighting system.

Background of the technique

With respect to the prior art, furniture is known that comprises a fixed structure resting on the floor and one or more shelves to be assembled, provided with lighting devices for the displayed articles, such as, for example, LED strips.

The electrical supply of the lighting devices is guaranteed by a connection with an electrical source, which is normally connectable to a first length of electrical cables installed in the fixed structure, for example, within special conduits, and which in turn are connectable to a second length of electrical cables installed on each shelf and connected to the corresponding lighting fixture.

The electrical connection between the first and second lengths of cables is generally made by means of special electrical connectors that can be removably coupled together to connect/disconnect the first and second lengths of cables, in order to allow assembly and disassembly. from the respective shelves.

However, since the electrical components are quite unsightly, they are hidden from view as much as possible, for example by hiding the first and second lengths of cables inside the fixed structure and shelves respectively. .

However, some elements, for example some cable parts or connectors, still remain exposed to view due to operational needs.

To overcome these problems, it has recently been known to use a series of magnetic induction coils (transmitters) installed in the fixed structure and a magnetic induction coil (receiver) installed in each shelf to be assembled, so that, after assembly , each transmitter is in contact with the corresponding receiver, with which it is magnetically coupled, allowing the flow of current and, therefore, the ignition of the corresponding lighting device.

In this way, there is no part of the electrical cable exposed to view and it is not necessary to use any electrical connector.

Furthermore, the transmitters are generally arranged in predetermined positions on the fixed structure and are in sufficient number to allow a certain customization of the furniture structure: for example, it is possible to have a number of shelves even smaller than the number of transmitters, deciding where placing only the desired shelves and thus obtaining a certain freedom in the composition of the furniture structure

Some representative arrangements of the prior art are described in patent documents EP 1950514 A1, US 2009/021927 A1 and EP 1760733 A1.

This prior art presents, however, a series of drawbacks, including the poor assembly flexibility of the furniture structure: in effect, the shelves can be mounted with a certain freedom, but only in predetermined positions, that is, on the transmitters.

Another drawback of the prior art is the fact that the transmitters receive electrical current continuously, so they consume energy even if they are not coupled to the corresponding receivers, for example, because the number of coupled shelves is less than the number of transmitters.

Furthermore, another drawback of the prior art is the fact that, despite being hidden as much as possible, the receiver and transmitter can be seen from the outside or other mechanical components are exposed to view, for example, such as small alignment portions that are generally used to ensure that the transmitters and receivers remain perfectly facing each other, worsening the overall aesthetics of the furniture structure.

Description of the invention

The main objective of the present invention is to provide a furniture structure with a lighting system that allows the shelves to be moved in arbitrary positions and more easily than in the prior art, without being forced to remain in predetermined positions.

Another object of the present invention is to increase the energy efficiency of electrical components, reducing current waste compared to the prior art.

Another object of the present invention is to provide a furniture structure with a lighting system, whose electrical and mechanical components are completely hidden from view, allowing a furniture structure of high aesthetic value to be obtained without penalizing its functionality.

A further object of the present invention is to provide a furniture structure with a lighting system in which the transmission power of the transmitters can be modulated depending on different factors, for example, depending on the distance that separates them from the corresponding receivers. .

Another object of the present invention is to devise a furniture structure with a lighting system that allows overcoming the aforementioned drawbacks of the prior art in the context of a simple, rational, easy, effective to use and affordable solution.

The aforementioned objects are achieved by the present furniture structure with lighting system according to claim 1.

Embodiments of the invention

With particular reference to these illustrations, the reference number 1 designates globally a furniture structure with a lighting system.

The furniture structure 1 comprises:

- at least one support structure 2;

- at least one magnetic induction transmitter 3 associated with the support structure 2 and connectable to an electrical source 4;

- at least one shelf 5, removably associated with the support structure 2 and provided with a lighting device 6;

- at least one magnetic induction receiver 7 located on the shelf 5, magnetically coupled to the transmitter 3 and adapted to power the lighting device 6.

With particular reference to the embodiment shown in Figures 1 to 3, the term support structure refers to any stable structure, such as for example a frame that is fixed to the wall or the structure of a piece of furniture/display that It can be permanently placed on the floor without having to be fixed to a wall or, in general, to a surface.

In more detail, the transmitter 3 is powered by the electrical source 4 and is adapted to generate a magnetic field that allows it to be coupled to a corresponding receiver 7, inducing within it an induction electric current used to power the lighting device 6.

Advantageously, the furniture structure 1 comprises distribution means for the electrical source 4 interposed between the latter and the transmitter 3 and adapted to make the electrical power necessary for the operation of the transmitter 3 accessible in different areas of the furniture structure 1.

In particular, the distribution means comprise at least one electrical conductor 31,32 that extends associated with the support structure 2 along a pre-established path and that is operatively connected to the electrical source 4, and at least one electrical connector 33 installed in the transmitter 3 and detachably connected to the electrical conductor 31, 32, in order to power the transmitter 3.

Advantageously, the electrical conductor 31, 32 comprises at least one support body 32 of insulating material, such as such as for example an extruded element, and at least one conductive body 31 associated with the support body 32, such as for example a copper track.

Preferably, the electrical conductor 31, 32 has a substantially rectilinear shape and extends substantially along the height of the support structure 2.

In this way, the transmitter 3 has access to the electrical source 4 through the distribution means along any point of the electrical conductor 31, 32, making it possible to power the transmitter 3 regardless of its position with respect to the structure. support 2.

Preferably, the transmitter 3 comprises a coil 8, which is wound in a plurality of turns 9 and generates a magnetic field when crossed by the electric current supplied by the electrical source 4.

Similarly, the receiver 7 comprises a respective coil 8, which is crossed by an induced electric current at the instant in which its turns 9 are crossed by the magnetic field generated by the coil 8 of the transmitter 3.

In this way, a mutual induction relationship can be established between the transmitter 3 and the receiver 7, allowing the transmission of power necessary to power the lighting device 6.

Indeed, the receiver 7, located on the shelf 5, is operatively connected to the lighting device 6, which turns on when the receiver 7 is magnetically coupled to the transmitter 3.

The transmitter 3 preferably comprises at least one ferromagnetic body, around which the coil 8 is wound and which defines a preferred path for the magnetic field lines.

Likewise, the receiver 7 preferably comprises at least one ferromagnetic body, around which the coil 8 is wound and which defines a preferred path for the magnetic field lines.

Furthermore, it is important to emphasize that the magnetic coupling between the transmitter 3 and the receiver 7 does not require that they be in contact with each other.

Indeed, the magnetic field, conveniently directed by the transmitter 3, extends from the latter several millimeters, which makes it possible to magnetically couple the transmitter 3 and the receiver 7 at a distance.

Advantageously, the furniture structure 1 comprises at least one fastening element 10 of the shelf 5 associated with the support structure 2, where the fastening element 10 has a plurality of recesses 11 arranged in predefined positions, and the shelf 5 comprises at least an engaging element 12 adapted to engage removably with the recesses 11.

In detail, the fastening element 10 has an elongated shape and the recesses 11 are arranged substantially along its longitudinal extension; Furthermore, the hooking element 12 comprises at least one projection 13, which is adapted to fit into the recesses 11 themselves.

In particular, in a preferred but not exclusive embodiment of the present invention shown in Figures 1 to 3, the assembly procedure of the fastening element 10 referred to in the present treaty is that described and represented in the document of Italian patent no. 0001417463.

In this embodiment, the furniture structure 1 comprises two fastening elements 10 arranged laterally to the furniture structure 1 and each shelf 5 comprises two hooking elements 12 arranged laterally to the shelf 5 itself.

However, the possibility of using a different number of fastening elements 10 and hooking elements 12 cannot be ruled out.

According to the invention, the furniture structure 1 comprises adjustment means 14 for adjusting the position of the transmitter 3 with respect to the support structure 2.

Advantageously, the adjustment means 14 are configured to allow movement of the transmitter 3 along at least one of:

- an adjustment direction 15, 16 belonging to an adjustment plane 17;

- an approach/departure direction 18 with respect to the adjustment plane 17.

Conveniently, the adjustment plane 17 is arranged substantially vertically.

In the particular embodiment shown in the illustrations, the adjustment plane 17 coincides with the surface of the support structure 2 and the adjustment means 14 are adapted to allow movement of the transmitter 3 along at least a first adjustment direction. 15, substantially vertical, and a second adjustment direction 16, substantially horizontal.

However, the possibility that the adjustment plane 17 is inclined differently, for example because the support structure 2 is inclined with respect to the vertical direction, cannot be ruled out, so the possibility of that the first adjustment direction 15 and the second adjustment direction 16 are inclined differently with respect to what is described.

Advantageously, the approach/departure direction 18 is incident with the adjustment plane 17.

In the particular embodiment illustrated in the figures, the approach/departure direction 18 is substantially orthogonal to both the first adjustment direction 15 and the second adjustment direction 16, so it is positioned substantially horizontal.

In the specific embodiment shown in the illustrations, the adjustment means 14 comprises:

- a guide element 19 extending along a first adjustment direction 15, where the transmitter 3 is movable with respect to the guide element 19 along the first adjustment direction 15 itself;

- a plate element 20 interposed between the support structure 2 and the guide element 19 and provided with first slots 21 for adjusting its position with respect to the support structure 2 along a second adjustment direction 16 and second slots 22 for adjusting the position of the guide element 19 with respect to the plate element 20 itself along the approach/departure direction 18;

- removable fastening means 23a, 23b, 23c of the plate element 20 to the support structure 2 and to the guide element 19 and from the transmitter 3 to the guide element 19 itself.

Therefore, the plate element 20 is fixed to the supporting structure 2 by first fastening means 23a inserted into the first slots 21 (extending along the second adjustment direction 16), and is fixed to the guide element 19 by second fastening means 23b inserted in the second slots 22 (extending along the approach/departure direction 18); In this way, the guide element 19 is locked together with the support structure 2.

The transmitter 3 can be moved relative to the guide element 19 along the first adjustment direction 15 and, once the desired position is reached, it can be fixed by the third fastening means 23c.

Preferably, the electrical source distribution means 4 extend parallel to the guide element 19 along the adjustment direction 15.

In particular, in the embodiments of the furniture structure 1 shown in the illustrations, the distribution means are removably fixed to the guide element 19.

In this way, the electrical connector 33 can be easily disconnected from the electrical conductor 31, 32 whenever the transmitter 3 has to be moved to freely adjust its position along the guide element 19, and can be easily connected to the electrical conductor 31, 32 once. once the position of transmitter 3 has been set.

However, alternative embodiments of the distribution means cannot be ruled out in which the electrical connector 33 is slidably coupled to the electrical conductor 31, 32, for example, by means of a sliding contact along the body of the conductor 31, which which allows it to slide along the electrical conductor itself during adjustment of the position of the transmitter 3 along the guide element 19.

Therefore, the first slots 21 allow the position of the plate element 20, and therefore the transmitter 3, to be adjusted with respect to the support structure 2 along the second adjustment direction 16, and the second slots 22 they allow the position of the guide element 19, and therefore of the transmitter 3, to be adjusted with respect to the plate element 20 along the approach/departure direction 18.

In this way, the position of the transmitter 3 can be modified as necessary along the first adjustment direction 15, along the second adjustment direction 16 and along the approach/departure direction 18, i.e. in all directions of space.

In the specific example shown in Figures 1 and 3, the fastening means 23a, 23b are of the screw type, which can be easily screwed and unscrewed by hand to change the position of the plate element 20 and the guide element 19 as necessary .

However, the possibility of using other fastening means 23a, 23b, such as, for example, pins, cannot be ruled out.

On the other hand, the third fastening means 23c advantageously comprise at least one element for engaging/disengaging the transmitter 3 that can move between a fixed configuration, in which the transmitter 3 is fixed to the guide element 19, and an adjustment configuration. , in which the transmitter 3 is slidably coupled to the guide element 19, allowing it to slide along the adjustment direction 15.

Preferably, the engagement/disengagement element is of the type of an adjustment screw with a spring that can be operated manually.

However, alternative embodiments of the third fastening means 23c cannot be ruled out in which the hooking/unhooking element can be activated automatically by remote control.

Furthermore, it cannot be ruled out that the fastening means 23a, 23b are also of the same type as the third fastening means 23c.

Conveniently, the furniture structure 1 comprises a plurality of transmitters 3 and relevant adjustment means 14 for moving them relative to the support structure 2 in a mutually independent manner.

In more detail, each transmitter 3 can move independently of the others thanks to the fact that it is individually associated with the guide element 19 and is individually connectable to the distribution means, and can be removed as necessary.

According to an alternative embodiment not shown in the illustrations, the adjustment means are of the automated adjustment type and comprise movement means that can be controlled remotely, such as for example electric motors kinematically connected to the transmitters 3 and controlled remotely by means of remote controls. special distance.

The electric motors are preferably associated with each transmitter 3 and kinematically coupled to the guide element 19 to allow, when activated, to move the transmitters themselves without the need for manual intervention. The transmitters 3, in fact, are removably associated with the support structure 2.

The furniture structure 1 advantageously comprises a covering element 24 associable to the support structure 2, accessible from the outside and adapted to define a containment chamber 25 of the transmitters 3, of the distribution means of the electrical source 4 and of the adjustment means 14.

In particular, the covering element 24 is movable between a working position, in which it makes the containment chamber 25 inaccessible from the outside, and an adjustment position, in which it makes the containment chamber 25 accessible. from the outside.

The operating position is shown schematically in Figures 2 and 3, while the adjustment position is reached by moving the covering element 24 with respect to the support structure 2.

In the specific embodiment shown in the illustrations, the covering element 24 is of the type of a panel, for example, made of wood materials, which, in the operating position, completely hides from view all the components located in the containment chamber 25.

Furthermore, the possibility of using a different covering element 24, for example of the type of a sheet or a lining, and/or of different materials, such as, for example, fabrics, plastics or stone materials, cannot be excluded.

The furniture structure 1 conveniently comprises at least one support element 26 of the covering element 24 associated with the support structure 2.

In more detail, the support element 26 comprises support means 27 against which the covering element 24 rests.

Therefore, the support means 27 are arranged in use behind the covering element 24.

In the specific example shown in the illustrations, the support elements 26 coincide with the fastening elements 10 and their purpose is to hold both the covering element 24 and the shelves 5, avoiding the need to use other components exposed to view.

However, the possibility of using support elements 26 other than the fastening elements 10 cannot be ruled out.

The shelf 5 advantageously comprises an interface surface 28, facing the covering element 24, and a recess 29, obtained in the interface surface 28 for housing the receiver 7.

More specifically, the receiver 7 has a portion facing the covering element 24 and substantially coplanar to the interface surface 28 with the receiver 7 housed in the recess 29.

Therefore, when the receiver 7 is positioned within the recess 29, the interface surface 28 is substantially flat and, when directed towards the covering element 24, completely hides the receiver 7 from view.

The furniture structure 1 conveniently comprises adjustment means for adjusting the power transmitted from the transmitter 3 to the receiver 7 as a function of at least one of the distances of the transmitter 3 and the corresponding receiver 7 along the approach/departure direction 18. and the power absorbed by the lighting device 6 of the corresponding receiver 7.

Absorbed power means the power generally specified by the manufacturers of these devices.

In fact, depending on the lighting needs, the shelves 5 can be provided with lighting devices 6 that require different power sources depending on the lumens of luminous flux that they are capable of emitting and the size of the lighting devices 6 .

Furthermore, in operating position, while the transmitters 3 are positioned within the containment chamber 25, the receivers are positioned within the respective recesses 29 and are therefore separated from the transmitters 3 by the thickness of the holding element. covering 24, which can have different thicknesses depending on the construction options of the furniture structure 1.

In particular, the furniture structure 1 can be provided with covering elements 24 with thicknesses between about 5 and 20 millimeters.

Advantageously, in the event that the covering element 24 has to be replaced by another of different thickness, the adjustment means 14 allow the position of the cover to be varied.

transmitters 3 to be more in contact with the new panel 24, limiting the power consumption of transmitters 3.

However, as is known, the distance between the transmitters 3 and the receivers 7 increases, that is, the more the thickness of the mounted panel 24 increases, the more the intensity of the magnetic field that, coming from the transmitter 3, reaches the receiver 7 decreases. ; The resulting effect is a decrease in the electrical current induced in receptor 7.

For these reasons, the power adjustment means are configured to increase or reduce the current flowing along the coil 8 of the transmitter 3, that is, to increase or reduce the intensity of the magnetic field emitted by the transmitter 3, in function of the power absorption of the lighting device 6 installed in the corresponding receiver 7 and the distance of the latter from the transmitter 3. In fact, as long as the distance between the transmitter 3 and the receiver 7 remains unchanged, as a first lighting device 6, powered by the transmitter 3, is replaced by a second that requires a higher power compared to the first, the power adjustment means automatically increases the power transmitted by the transmitter 3, and therefore the magnetic field emitted by the same, turning on the second lighting device 6.

Likewise, as soon as a first lighting device 6 is replaced by a second one that requires less power than the first, the power adjustment means automatically reduces the power transmitted by the transmitter 3, thus limiting its energy consumption within the limits. limits imposed by the ferromagnetic elements placed in the transmitter 3 and the receiver 7.

Indeed, the power transmitted by the transmitter 3 must not be less than a lower limit threshold defined by the minimum power absorbed by the ferromagnetic element of the transmitter 3 and below which the latter is unable to power the lighting device 6.

In an analogous manner to what has just been described, as long as the lighting device remains unchanged, as soon as the distance between a transmitter 3 and the corresponding receiver 7 is increased, the power adjustment means automatically increase the power transmitted by the transmitter. 3, keeping the lighting device 6 of the transmitter 3 on, within the limits imposed by nature and by the ferromagnetic elements placed in the transmitter 3 and the receiver 7.

On the contrary, as soon as the distance between a transmitter 3 and the corresponding receiver 7 is reduced, the power adjustment means automatically reduce the power transmitted by the transmitter 3, thus limiting its power consumption and preventing phenomena from occurring. of overcurrent inside the receiving device 7, which can cause its malfunction or even breakage 7.

Furthermore, when a transmitter 3 is not coupled to any receiver 7, the power adjustment means automatically reduces the power consumption of the transmitter 3 to a minimum, for example by temporarily turning off the transmitter itself.

Preferably, the power adjustment means are configured to limit the maximum intensity of the magnetic field emitted by the transmitter 3 within the limits required by law.

Furthermore, the power adjustment means preferably comprises at least one electronic control device operatively connected to the transmitter 3 and adapted to adjust the power transmitted from it to a corresponding receiver 7. Optionally, the power adjustment means also comprise an electronic control device operatively connected to the transmitter 3 and adapted to operate jointly with the electronic control device operatively connected to the transmitter 3 to optimize the adjustment of the power transmitted from it to the corresponding receiver 7. .

Advantageously, the furniture structure 1 comprises drive means 30a, 30b of the transmitters 3 configured to activate the magnetic coupling between the transmitters 3 and the receivers 7 and provided with:

- at least one first electronic control device 30a operatively connected to at least one corresponding receiver 7 and configured to modulate the magnetic induction of the receiver 7 on a transmitter 3 to obtain a predefined magnetic induction; and

- at least a second electronic control device 30b operatively connected to a transmitter 3 and configured to identify the magnetic induction of the transmitter 3 on the receiver 3.

In particular, the second electronic control device 30b is configured to activate the magnetic coupling between the transmitter 3 and the receiver 7 upon identification of the predefined magnetic induction of the transmitter 3 on the receiver 3.

More in detail, the first electronic control device 30a is configured to modulate the current pulses induced by the transmitter 3 in the coil 8 of the receiver 7, where said pulses are adapted to generate in turn the predefined magnetic induction in the coil 8 of transmitter 3.

Indeed, the second electronic control device 30b is configured to identify said predefined modulation carried out by the first electronic control device 30a. In this way, the second electronic control device 30b allows the transmitter 3 to activate the magnetic field adapted to power the transmitter 3 only at the instant in which the magnetic induction of the latter on the transmitter 3 is suitably modulated by the first control board electronic 30a.

In fact, if the furniture structure 1 lacks the drive means 30a, 30b, the transmitter 3 could activate the magnetic field to power the receiver 7 even if it were in front of any object made of ferrous material, causing thus the dissipation of energy and heat.

Preferably, the furniture structure 1 comprises a plurality of first and second electronic control devices 30a, 30b, where each transmitter 3 is operatively connected to a corresponding first electronic control device 30a and each receiver 3 is operatively connected to a corresponding second device electronic control 30b.

However, alternative embodiments of the furniture structure 1 cannot be ruled out in which the drive means 30a, 30b comprise a second individual electronic control device 30b operatively connected to each of the transmitting elements 3 and configured to adjust the operation of each of the latter.

Preferably, the first electronic control device 30a and the second electronic control device 30b coincide with the electronic control device operatively connected to the receiver 7 and with the electronic control device operatively connected to the transmitter 3, respectively.

Figure 4 shows an alternative embodiment of the furniture structure 1 in which the support structure 2 coincides with the surface of a building, for example, the wall of a room.

In particular, this embodiment differs from the previously described one in that the transmitters 3 are associated with the surface of the building by means of the interposition of the adjustment means 14.

Figure 5 shows another embodiment of the furniture structure 1 in which the support structure 2 comprises at least one front covering element 34 arranged substantially opposite the covering element 24, and in which the transmitters 3 are associated with the covering 34 by interposition of the adjustment means 14.

In particular, the term frontally refers to the facade of the furniture structure 1 on which the shelves 5 are placed.

Indeed, unlike what has been described with reference to the previous embodiments, the support structure 2 and the covering element 24 are arranged at the front and rear respectively with respect to the furniture structure 1. Furthermore, the Transmitters 3 are oriented towards the inner face of the containment chamber 25 of the covering element 34, so that the magnetic field is directed through the latter and out of the containment chamber itself.

Indeed, in this embodiment, the adjustment plane 17 coincides with the inner face of the containment chamber 25 of the covering element 34. Advantageously, as shown in Figure 5, in this embodiment, the support structure 2 is arranged in stable support on the ground and does not need to be supported and/or fixed to a wall or a generic vertical surface as described in the previous embodiment.

Preferably, the covering element 34 is of the panel type, for example of wood materials.

In practice it has been proven that the described invention achieves the intended objects and, in particular, the fact is highlighted that the furniture structure with lighting system to which the present invention refers allows, thanks to the use of the means of adjustment, moving the shelves in arbitrary positions and with greater ease compared to the previous technique, without the obligation to be fixed to predetermined positions.

Furthermore, the present invention increases the energy efficiency of the furniture structure, thus reducing the waste of current compared to the prior art, since it is possible to mount and connect to the electric current a number of transmitters equal to the number of receivers and dismantle unused transmitters.

Furthermore, in the present furniture structure with lighting system, the electrical and mechanical components are completely hidden from view, which allows obtaining a furniture structure of great aesthetic appeal without penalizing its functionality.

Finally, it is evident that the structure of the furniture to which the present invention refers has a wide flexibility of use and continuous adjustment of its shelves.
