Description

Furniture structure with lighting system

Technical Field

The present invention relates to a furniture construction with a lighting system.

Background

With regard to the prior art, furniture is known comprising a fixed structure on the ground and one or more shelves to be assembled, having lighting devices, such as LED strips, for displaying items on the shelves.

The powering of the lighting devices is ensured by the connection to a power source, which is generally connectable to a first length of cable mounted on the fixed structure (for example, inside a special duct), and which is in turn connectable to a second length of cable mounted on each shelf and connected to the corresponding lighting device.

The electrical connection between the first and second lengths of cable is usually achieved by means of special electrical connectors which are coupled to each other in a removable manner to connect/disconnect the first and second lengths of cable, thus allowing the assembly and disassembly of the respective shelves.

However, since the electrical components are rather unsightly, they are hidden from view as much as possible, for example, by hiding the first and second lengths of cable within the fixed structure and shelf, respectively.

Nevertheless, parts of the components, for example a part of the cable or connector, are exposed in the line of sight as required for the operation.

To overcome these problems, it is known to use recently a series of magnetic induction coils (transmitters) mounted on a fixed structure and a magnetic induction coil (receiver) mounted on each shelf to be mounted, so that, after assembly, each transmitter is in contact with, and magnetically coupled to, the corresponding receiver, so that an electric current flows, thus lighting the corresponding lighting device.

Thus, there is no portion of the cable exposed to the line of sight and no electrical connector is necessary to connect the first and second lengths of cable.

Furthermore, the emitters are generally arranged in predetermined positions on the fixed structure and in sufficient numbers to allow specific customization of the furniture structure: for example, it is even possible that the number of shelves is less than the number of emitters, only determining where to place the desired shelf, so that a certain degree of freedom is obtained in the construction of the furniture structure.

However, this prior art has a number of disadvantages, including limited flexibility in assembly of the furniture structure: in practice the customization of the shelf may have a certain degree of freedom, but can only be mounted at a predetermined position, such as at the emitter.

Another disadvantage of the prior art is that the emitters continuously receive current and therefore consume energy even if they are not connected to a corresponding receiver, e.g. the number of customized shelves is smaller than the number of emitters.

Furthermore, another drawback of the prior art is that, although hidden as much as possible, the receiver and the transmitter, or other mechanical type components (for example, a small portion for calibration, which is generally used to ensure that the transmitter and the receiver remain perfectly facing each other), can be seen from the outside, being exposed in line of sight, which impairs the overall aesthetic appearance of the furniture structure.

Disclosure of Invention

The main object of the present invention is to provide a furniture structure with a lighting system which, compared to the prior art, makes it easier to move shelves in any position without having to remain in a predetermined position.

Another object of the invention is to improve the energy efficiency of the electrical components and to reduce current waste compared to the prior art.

Another object of the present invention is to provide a furniture structure with a lighting system, the electrical and mechanical elements of which are totally hidden from view, so as to enable to obtain a furniture structure with high aesthetic value without compromising its function.

Another object of the invention is to provide a furniture construction with a lighting system in which the transmission power of the transmitter can be adjusted according to different factors, for example according to the distance separating the transmitter from the corresponding receiver.

Another object of the present invention is to devise a furniture structure with a lighting system which allows to overcome the above mentioned drawbacks of the prior art, with a simple, rational, easy, effective to use and cost-effective solution.

The above object is achieved by a furniture construction with a lighting system of the present application as claimed in claim 1.

Detailed Description

With particular reference to these figures, reference numeral 1 denotes in its entirety a furniture construction with a lighting system.

The furniture structure 1 includes:

at least one support structure 2;

at least one magnetic induction transmitter 3 associated with the support structure 2 and connectable to a power source 4;

at least one shelf 5, associated in a removable manner with the support structure 2 and having lighting means 6;

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

With particular reference to the embodiments shown in fig. 1 to 3, the term "support structure" refers to any stable structure, for example a frame fixed to a wall or a piece of furniture structure/display unit structure, which can be placed permanently on the ground without being attached to a wall or generally to a surface.

In more detail, the emitter 3 is powered by the power source 4 and is able to generate a magnetic field, able to couple to the corresponding receiver 7, generating inside it an electrically induced current to power the lighting device 6.

Preferably, the furniture structure 1 comprises distribution means of the power source 4, interposed between the power source 4 and the emitter 3, and making accessible the power supply necessary for the operation of the emitter 3 in the different zones of the furniture structure 1.

In particular, the distribution means comprise at least one

electrical conductor

31, 32 and at least one electrical connector 33, said

electrical conductor

31, 32 extending along a pre-established path in association with said support structure 2 and being operatively connected to said power source 4; said electrical connector 33 is mounted on the emitter 3 and is connected in a removable manner to the

electrical conductors

31, 32 so as to supply the emitter 3 with electricity.

Preferably, the

electrical conductors

31, 32 comprise: at least one support body 32 made of insulating material, for example an extruded element; and at least one conductor body 31, for example a copper track, associated with the support body 32.

Preferably, the

electrical conductors

31, 32 are substantially rectilinear in shape and extend substantially along the height of the support structure 2.

In this way, the emitter 3 is connected to the power source 4 by the distribution means, at any point along the

electrical conductors

31, 32, so as to be able to be powered irrespective of the position of the emitter 3 with respect to the support structure 2.

Preferably, the transmitter 3 comprises a coil 8, the coil 8 being wound as a plurality of spirals 9 and generating a magnetic field when the coil 8 is traversed by a current supplied by the power source 4.

Similarly, the receiver 7 comprises a corresponding coil 8, through which coil 8 the current is induced at the instant the magnetic field generated by the coil 8 of the transmitter 3 passes through the spiral 9 of the coil 8 of the receiver 7.

In this way, a mutual inductive relationship can be established between the transmitter 3 and the receiver 7, thereby enabling the power transfer required for powering the lighting device 6.

In practice, the receiver 7 located on the shelf 5 is operatively connected to the lighting device 6, the lighting device 6 being lit when the receiver 7 is magnetically coupled to the transmitter 3.

Preferably, the transmitter 3 comprises at least one ferromagnetic body around which the coil 8 is wound and which defines a preferential path of the magnetic field lines.

Similarly, 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, one must emphasize the fact that the magnetic coupling between the transmitter 3 and the receiver 7 does not require that the two are in contact with each other.

In fact, the magnetic field suitably directed by the transmitter 3 extends from the transmitter by a few millimetres, enabling the geomagnetic coupling of the transmitter 3 and the receiver 7 remotely.

Preferably, the furniture structure 1 comprises at least one retaining element 10 of the shelf 5 associated with the support structure 2, wherein the retaining element 10 has a plurality of grooves 11 provided in predetermined positions, and the shelf 5 comprises at least one hooking element 12 which can be engaged in a removable manner with the grooves 11.

In particular, the retaining element 10 has an elongated shape and the groove 11 is arranged substantially along its longitudinal extension; furthermore, the hooking element 12 comprises at least one protrusion 13, which is itself able to be inserted in the groove 11.

In particular, in the preferred but not exclusive embodiment of the invention shown in figures 1 to 3, the assembly procedure of the holding element 10 cited herein is the one described and represented in italian patent application 0001417463.

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

However, it is not excluded that a different number of retaining elements 10 and hook elements 12 can be used.

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

Preferably, the adjustment means 14 are configured to enable the emitter 3 to move along at least one of the following directions:

adjustment directions

15, 16 belonging to an adjustment plane 17;

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

Conveniently, the adjustment plane 17 is arranged substantially vertically.

In the embodiment shown in the figures, the adjustment plane 17 coincides with the surface of the support structure 2, and the adjustment device 14 is able to move the emitter 3 in at least one of a first adjustment direction 15, which is substantially vertical, and a second adjustment direction 16, which is substantially horizontal.

However, the possibility of the adjustment plane 17 being inclined in a different manner is not excluded, for example, because the support structure 2 is inclined with respect to the vertical direction, the possibility of the adjusted first direction 15 and the adjusted second direction 16 being inclined in a different manner with respect to the described vertical direction cannot be excluded.

Preferably, the approach/departure direction 18 is associated with the (incident to) adjustment plane 17.

In the particular embodiment shown in the figures, the approach/departure direction 18 is substantially mutually orthogonal to both the first adjustment direction 15 and the second adjustment direction 16, and is therefore substantially horizontal.

In the particular embodiment shown in the figures, the adjustment device 14 comprises:

a guide element 19 extending along the first adjustment direction 15, the emitter 3 itself being movable with respect to the guide element 19 along the first adjustment direction 15;

a plate element 20, interposed between the support structure 2 and the guide element 19, having a first slot 21 and a second slot 22, said first slot 21 being intended to adjust its position with respect to the support structure 2 in the second adjustment direction 16, said second slot 22 being intended to adjust the position of the guide element 19 itself with respect to the plate element 20 in the approaching/departing direction 18;

removable fastening means 23a, 23b, 23c of the plate element 20 with respect to the support structure 2 and to the guide element 19 and of the emitter 3 with respect to the guide element 19 itself.

The plate element 20 is therefore fixed to the supporting structure 2 by first fastening means 23a inserted in the first slot 21 (extending in the second adjustment direction 16) and to the guide element 19 by second fastening means 23b inserted in the second slot 22 (extending in the approaching/separating direction 18); in this way, the guide element 19 is locked with the support structure 2.

The emitter 3 is movable in the first adjustment direction 15 relative to the guide element 19 and, once the desired position has been reached, can be fixed by means of the third fastening means 23 c.

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

In particular, in the embodiment of the furniture construction 1 shown in the figures, the dispensing device is detachably fixed on the guide element 19.

In this way, the electrical connector 33 can be easily disconnected from the

electrical conductors

31, 32 whenever the emitter 3 has to be moved to freely adjust its position along the guiding element 19, and the electrical connector 33 can be easily connected to the

electrical conductors

31, 32 once the position of the emitter 3 is fixed.

However, alternative embodiments of the dispensing device cannot be excluded, in which the electrical connector 33 is slidably coupled to the

electrical conductors

31, 32, for example by sliding contact along the conductor body 31, enabling itself to slide along the electrical conductors during the adjustment of the position of the emitter 3 along the guide element 19.

Thus, the first slot 21 enables the position of the plate element 20 and the emitter 3 with respect to the support structure 2 to be adjusted along the second adjustment direction 16, and the second slot 22 enables the position of the guide element 19 and the emitter 3 with respect to the plate element 20 to be adjusted along the approach/departure direction 18.

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

In the particular example shown in fig. 1 and 3, the fastening means 23a, 23b are of the screw type, which can be easily screwed and unscrewed manually to change the position of the plate element 20 and of the guide element 19 as required.

However, the possibility of using different fastening means 23a, 23b, such as pins, is not excluded.

On the other hand, it is preferred that the third fastening means 23c comprise at least one hooking/unhooking element of the emitter 3, which is movable between a fixed configuration and an adjusted configuration; in the fixed configuration the emitter 3 is fixed on the guiding element 19, in the adjusted configuration the emitter 3 is slidably coupled to the guiding element 19 allowing it to slide along the adjustment direction 15.

Preferably, the hooking/unhooking element is of the adjusting screw type with a spring that can be activated manually.

However, alternative embodiments of the third fastening means 23c are not excluded, wherein the hooking/unhooking element can be automatically activated by remote control.

Furthermore, it is not excluded that the fastening means 23a, 23b are also of the same type as the third fastening means 23 c.

Conveniently, the furniture structure 1 comprises a plurality of launchers 3 and corresponding adjustment devices 14 for moving these launchers 3 relative to the support structure 2 in a mutually independent manner.

In more detail, each emitter 3 is able to move independently with respect to the others, since it is individually associated with the guiding element 19 and can be individually connected to the dispensing device, and can also be removed as required.

According to an alternative embodiment, not shown in the figures, the adjustment means are of the automatic adjustment type and comprise a mobile device that can be remotely controlled, for example an electric motor dynamically connected to the transmitter 3 and remotely controlled by means of a special remote control.

Preferably, an electric motor is associated with each emitter 3 and is dynamically coupled to the guiding element 19, so as to allow the movement of the emitter itself when activated, without manual intervention.

In fact, the emitter 3 is associated with the support structure 2 in a removable manner.

Preferably, the furniture structure 1 comprises a covering element 24 associated with the support structure 2, which covering element 24 is accessible from the outside and is able to delimit a closed chamber 25 of the emitter 3, the distribution means of the power source 4 and the adjustment means 14.

In particular, the covering element 24 is movable between a working position, in which it does not allow access to the closed chamber 25 from the outside, and an adjustment position, in which it allows access to the closed chamber 25 from the outside.

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

In the embodiment shown in the figures, the covering element 24 is of the panel type, for example made of wood material, which completely hides all the components in the closed chamber 25 in the operating position.

Furthermore, the possibility of using different covering elements 24, such as sheets or linings or the like, and/or different materials, such as fabric, plastic or stone, is not excluded.

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

In more detail, the supporting element 26 comprises bearing means 27, the covering element 24 being supported on the bearing means 27.

Thus, in use the support means 27 is arranged behind the cover element 24.

In the particular example shown in the figures, the support element 26 coincides with the retaining element 10, the purpose of which is to retain the covering element 24 and therefore the shelf 5, avoiding the need to use other components exposed to the field of view.

However, the possibility of using the support element 26 instead of the holding element 10 is not excluded.

Preferably, the shelf 5 comprises an interface 28 facing the covering element 24 and a recess 29, the recess 29 being located on the interface 28 for receiving the receiver 7.

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

Thus, when the receiver 7 is placed in the recess 29, the interface 28 is substantially flat and faces the cover element 24, completely hiding the receiver 7 from view.

Conveniently, the furniture structure 1 comprises adjustment means to adjust the power emitted from the emitter 3 to the receiver 7 as a function of at least one of the distance of the emitter 3 from the receiver 7 along the approaching/departing direction 18 and the power absorbed by the lighting device 6 of the receiver 7.

The term "absorbed power" is used herein to denote the power typically specified by the manufacturer of such devices.

In fact, the shelf 5 may be provided with lighting devices 6 according to the lighting needs, the lighting devices 6 requiring different power supplies according to the brightness of the light beam that they are able to emit and the size of the lighting devices 6.

Furthermore, in the operating position, when the emitter 3 is located in the closed chamber 25, the receivers are placed in the respective recesses 29, thus being spaced apart from the emitter 3 by the thickness of the covering element 24, the covering element 24 being able to have different thicknesses, depending on the constructive choice of the furniture structure 1.

In particular, the furniture structure 1 can be fitted with a covering element 24 having a thickness in the range from about 5 mm to 20 mm.

Preferably, in the case where the covering element 24 is replaced by another covering element 24 of different thickness, the adjustment means 14 are able to change the position of the emitter 3 so as to be in more contact with the new panel 24, thus limiting the power consumption of the emitter 3.

However, it is well known that the greater the increase in the distance between the transmitter 3 and the receiver 7, for example, the greater the increase in the thickness of the mounting panel 24, the more the magnetic field strength from the transmitter 3 to the receiver 7 decreases; the effect of this is that the current induced in the receiver 7 is reduced.

For these reasons, the power adjusting means are configured to increase or decrease the current flowing along the coil 8 of the transmitter 3, i.e. depending on the power consumption of the lighting devices 6 mounted on the respective receivers 7 and the distance from the transmitter 3 to the receivers 7, the intensity of the magnetic field emitted by the transmitter 3,

in fact, as long as the distance between the emitter 3 and the receiver 7 remains constant, the power adjustment means automatically increases the power emitted by the emitter 3, and therefore the magnetic field emitted by the emitter 3, so as to light the second lighting device 6, once the first lighting device 6 powered by the emitter 3 is replaced with a second lighting device 6 that requires a higher power than the first lighting device.

Similarly, the power adjustment means automatically reduces the power emitted by the emitter 3, limiting its power consumption within the limits imposed by the ferromagnetic elements located in the emitter 3 and in the receiver 7, once the first lighting device 6 is replaced with a second lighting device 6 that requires less power than the first lighting device.

In fact, the power emitted by the emitter 3 must not fall below a lower threshold defined by the minimum power consumed by the ferromagnetic elements of the emitter 3, and below this threshold the emitter 3 cannot power the lighting device 6.

In the same way as described above, as long as the lighting device remains unchanged, the power adjustment means automatically increase the power emitted by the emitter 3 as soon as the distance between the emitter 3 and the corresponding receiver 7 increases, the lighting device 6 holding the emitter 3 being within the limits imposed by its intrinsic and ferromagnetic elements placed in the emitter 3 and in the receiver 7.

Conversely, once the distance between the emitter 3 and the corresponding receiver 7 is reduced, the power regulation means automatically reduce the power emitted by the emitter 3, thus limiting the power consumption of the emitter 3 and avoiding the occurrence of overcurrent phenomena inside the receiver means 7, which can lead to the malfunctioning or even the destruction of the emitter 7.

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

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

Furthermore, preferably, the power adjustment means comprise at least one electronic control means operatively connected to the transmitter 3 and capable of adjusting the power transmitted from the transmitter 3 to the respective receiver 7.

Optionally, the power adjustment means further comprise electronic control means operatively connected to the transmitter 3, operable with the electronic control means operatively connected to the transmitter 3, to optimize the adjustment of the power sent from the transmitter 3 to the respective receiver 7.

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

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

at least one second electronic control device 30b operatively connected to the transmitter 3 and configured to recognize the magnetic induction of the transmitter 3 on the receiver 7.

In particular, the second electronic control means 30b are configured to activate the magnetic coupling between the transmitter 3 and the receiver 7 after identifying a predetermined magnetic induction of the transmitter 3 on the receiver 7.

In more detail, the first electronic control means 30a are configured to regulate the current pulses induced by the transmitter 3 on the coil 8 of the receiver 7, wherein these pulses are able to in turn generate a predetermined magnetic induction on the coil 8 of the transmitter 3.

In fact, the second electronic control device 30b is configured to recognize such predetermined adjustment carried out by the first electronic control device 30 a.

In this way, the second electronic control means 30b allow the emitter 3 to trigger a magnetic field suitable for powering the emitter 3 only when the magnetic induction on the emitter 3 is suitably regulated by the first electronic control means 30 a.

In fact, if the furniture structure 1 has no drive means 30a, 30b, the transmitter 3 can trigger a magnetic field to power the receiver 7 in the case where it faces any object made of ferrous material, thus causing power and heat dissipation.

Preferably, the furniture structure 1 comprises a plurality of first and second

electronic control devices

30a, 30b, wherein each transmitter 3 is operatively connected to a corresponding first electronic control device 30a and each receiver 7 is operatively connected to a corresponding second electronic control device 30 b.

However, alternative embodiments of the furniture structure 1 cannot be excluded, in which the drive means 30a, 30b comprise a single second electronic control device 30b, which second electronic control device 30b is operatively connected to each emitter element 3 and is configured to regulate the operation of each emitter element 3.

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

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

In particular, this embodiment differs from the previously described embodiment in that the emitter 3 is associated with the surface of the building by the insertion of the adjustment device 14.

Fig. 5 shows another embodiment of the furniture construction 1, wherein the support structure 2 comprises at least one front cladding element 34, which front cladding element 34 is arranged substantially opposite to the covering element 24, and wherein the emitter 3 is associated with the cladding element 34 by insertion of the adjustment device 14.

In particular, the term "front" refers to the front face (facade) of the furniture structure 1 on which the shelf 5 is placed.

In fact, unlike the previously described embodiments, the support structure 2 and the covering element 24 are arranged respectively at the front and at the rear with respect to the furniture structure 1.

Furthermore, the emitter 3 is directed towards the inner surface of the closed chamber 25 of the cladding element 34, so as to direct the magnetic field through the latter, outside the closed chamber.

In fact, in the present embodiment, the adjustment plane 17 coincides with the inner surface of the closed chamber 25 of the coating element 34.

Preferably, as shown in fig. 5, in the present embodiment, the support structure 2 is a stable support arranged on the ground and does not need to be supported and/or fixed on a wall or a general vertical surface as described in the previous embodiment.

Preferably, the cladding element 34 is of the flat plate type, for example made of wood material.

It has been confirmed in practice that said invention achieves the intended aim, and particular emphasis is given to the fact that the furniture construction with lighting system to which the invention relates, thanks to the use of adjustment means, enables the shelves to be moved in any position, and that it is easier to move the shelves than in the prior art, without the need to fix them in a predetermined position.

Furthermore, the present invention improves the energy efficiency of the furniture structure compared to the prior art, thereby reducing the waste of current, since a number of transmitters equal to the number of receivers can be assembled and connected and unused transmitters can be disassembled.

In addition, in the furniture structure with the lighting system of the present invention, the electric and mechanical parts are completely hidden from view, and therefore a highly aesthetic furniture structure can be obtained without impairing the function of the furniture structure.

Finally, the fact clearly shows that the furniture structure to which the invention relates has sufficient flexibility of use and continuous adjustment of its shelves.
