â € œLIGHTING DEVICEâ €.

TECHNICAL FIELD OF INVENTION

The present invention relates to a lighting device.

More specifically, the invention relates to a lighting device to illuminate the work area when using tools of various types, in the context of carrying out domestic, professional or other work.

STATE OF THE PRIOR ART

It is known that in the execution of some works, be they domestic, professional or other work, a fundamental requirement to operate effectively and easily is the correct lighting of the work area.

For example, just to stay in the home, a typical example of such a situation is cleaning floors.

In the event that there is poor lighting in the environment, cleaning the floors is absolutely uncomfortable and difficult, and the results obtained are completely unsatisfactory.

For example, think about cleaning floors in areas that are poorly or not at all lit, such as certain corners hidden by furniture or other objects, or cleaning surfaces that lie completely under furniture, tables, chairs, armchairs, sofas, beds, etc. ..

Both in the case in which cleaning is carried out during the hours of solar lighting, and in which it is carried out during the hours in which artificial lighting is necessary, there are areas of the floors where the visibility is always very poor, with consequent negative effects on the obtainable result. Specifically in the area of the cleaning sector, solutions have been developed that attempt to overcome this problem, and mainly in the sector of the production of brooms, vacuum cleaners and the like.

The various existing solutions generally include a light source, powered for example by a battery, integrated directly into the head of the cleaning tool, for example a vacuum cleaner. The presence of this light source on the head of the cleaning tool allows to illuminate the area of the floor immediately surrounding the head itself.

A significant drawback that afflicts this type of solution is obviously the fact that the light source is permanently fixed to the tool head, and therefore cannot be used with other tools.

In other words, the user who has a vacuum cleaner with a head equipped with the light source cannot use the same light source when using, for example, a traditional broom, or any other utensil.

Furthermore, as mentioned, this known type solution allows to illuminate only the area immediately surrounding the cleaning head, but it is not possible to illuminate other areas of the work area as desired if this is necessary to obtain a good result.

Furthermore, the light source positioned in this area tends to accumulate dirt on its surface, and therefore to lose its effectiveness unless it is continuously cleaned.

AIMS OF THE INVENTION

The technical task of the present invention is to improve the state of the art.

Within the scope of this technical task, it is an object of the present invention to provide a lighting device for universal use, ie which can be effectively used in the execution of works with a wide range of tools.

Another object of the present invention is to make available a lighting device that allows to illuminate large areas of the work area, and also in an adjustable way in relation to the specific needs of the user.

This aim and these aims are all achieved by the lighting device according to the attached claim 1.

The lighting device, suitable for illuminating the work area when using tools of various types equipped with a handle, a handle, an extension, or the like, comprises a box-like support element, at least one light source provided on the external surface of the box-like element, means for feeding the light source and means for operating the light source itself.

According to an aspect of the present invention, the box-like element of the device comprises fastening means which can be connected to the handle or to the grip of the tool.

The dependent claims refer to preferred and advantageous embodiments of the invention.

FORMS OF IMPLEMENTATION OF THE INVENTION.

With reference to Figure 1, the reference numeral 1 generally indicates a lighting device according to the invention.

The device 1 according to the invention is suitable for illuminating the work area when using tools of various types provided with a handle, a grip or the like.

By way of illustrative and non-limiting example, these tools can consist of brooms, brushes, shovels for collecting rubbish, or other tools for cleaning environments.

However, more generally, the device according to the invention can be used to illuminate the work area when using tools of any type, as long as they are equipped with a handle, a grip, or other similar appendage. .

The device 1 comprises a box-like support element 2.

The device 1 further comprises at least one light source 3.

The light source 3 is provided on the external surface of the box-like element 2.

The device 1 also comprises means 4 for feeding the light source 3.

The device 1 also comprises means 5 for actuating the same light source 3.

According to an aspect of the present invention, the box-like element 2 of the device 1 comprises constraining means 6 which can be connected to the handle 7 or to the handle of the tool.

The handle 7 schematically illustrated in Figure 1 can be, for example, the handle of a broom, a scrub brush, a dustpan for collecting rubbish, or the like, without any limitation.

Alternatively, the handle 7 can be constituted by the extension rod of any known tool, for example to reach distant or awkward areas in the execution of a specific job.

In the continuation of the description, therefore, the element that is generically and synthetically indicated with handle 7 can actually be one of the aforementioned elements indifferently.

As will become clearer in the following, the locking means 6 allow to selectively lock the device 1 according to the invention in any position along the handle 7 of the tool, at the user's discretion, in order to illuminate the area of work from the desired height, and therefore to illuminate the area according to the desired angle and at the desired distance.

Furthermore, the fastening means 6 allow the device 1 according to the invention to be moved indifferently from one tool to another, in relation to the specific needs of use.

More in detail, the fastening means 6 comprise a seat 8 for inserting the handle 7 or the handle, or extension, of the tool.

The seat 8, in more detail, is provided in the box-like element 2.

The fastening means 6 also comprise means 9 for locking the handle 7, grip or extension within the seat 8.

The box-shaped element 2 can be of any shape, in relation to the particular needs of use.

In the embodiment of figures 1-4, the box-like element 2 comprises a front surface 10 on which at least one light source 3 is positioned.

More in detail, in the present embodiment three light sources 3 are provided, positioned on the front surface 10 of the box-like body 2. The front surface 10 is preferably convex, consisting for example of a portion of a cylindrical surface: in this way the sources luminous 3 are oriented in different directions, so as to illuminate a larger area.

Obviously the front surface 10 could be of any shape, for example even flat.

The box-like body 2 also comprises a rear surface 11, opposite to the front surface 10, in correspondence with which the seat 8 for inserting the handle 7 is provided.

Headquarters 8 is open; as illustrated in Figure 3, it can have a semi-cylindrical surface, or consisting of a portion of a cylindrical surface.

The box-like body 2 further comprises two lateral surfaces 12, diverging for example.

In the present embodiment, the locking means 9 of the handle 7 inside the seat 8 are of the clamp type, and also comprise a closing element 13 which can be coupled to the box-like element at the seat 8, i.e. in correspondence of the posterior surface 11.

The closing element 13 is shaped like an arch, for example, and defines an internal cylindrical surface 14 suitable for abutting on the lateral surface of the handle 7, as illustrated in figure 3.

The locking means 9 also comprise two screws 15, engaged in respective first through holes 16 of the closing element 13, and in respective second through holes 17 provided in the box-like element 2. The two screws 15 comprise respective heads 18 manual operation by the user.

More in detail, by acting on the heads 18 of the screws 15, it is possible to adjust the tightening of the closing element 13 against the lateral surface of the handle 7, so as to lock the device 1 along the handle 7 itself in the desired position .

The box-like element 2 also comprises an upper surface 19 and a lower surface 20.

In the embodiment shown, the upper surface 19 of the box-like element 2 consists of - or comprises - a removable cover, for access to the inside of the box-like element 2 itself.

Figure 4 shows the device 1 according to the invention with the aforementioned removable cover removed for greater clarity.

Inside the box-like element 2 there is an electronic board 21 for controlling the operation of the device 1.

Inside the box-like element 2 are also housed the means 4 for feeding the light sources 3.

The power supply means 4 can be constituted for example by batteries or rechargeable batteries, housed in a suitable compartment 22.

Alternatively, the power supply means 4 can be constituted by a piezoelectric generator, which is recharged with the simple movement of the tool during its use.

As illustrated in Figure 4, electrical connections 23 of a known type are provided between the power supply means 4 and the electronic board 21, and between the latter and the light sources 3.

The means 5 for actuating the light sources 3 of the device 1 comprise a button 24 for turning on and off the light sources 3 themselves.

The button 24 is provided on the external surface of the box-like element 2; in particular, the button 24 is provided on the upper surface 19 of the box-like element 2, so as to be easily accessible for the user.

The button 24 could however be provided in other areas of the external surface of the box-like element 2, in relation to possible different user requirements.

Furthermore, the button 24 could of course be replaced by other equivalent on and off devices for the light sources 3, for example a switch, a knob, or the like.

The light sources 3 of the device 1 are preferably of the LED type.

The choice of this type of light sources guarantees, as is well known, low consumption, long life and reduced dimensions.

In other embodiments, however, the light sources could be of another type, without limitation to the purposes of the present invention.

In some embodiments of the device according to the invention, the light sources 3 can be of the type which can be oriented independently of one another. This allows you to direct the light beams according to the directions desired by the user, for example in order to illuminate a large area as desired.

The electronic card 21 for controlling the operation of the device 1 can comprise means of chromatic variation of the radiation emitted by the light sources 3.

This allows, in some situations, to vary the color of the light emitted, for example to rest the sight of the operator who carries out repetitive operations for a long time observing the illuminated work area.

With the solution described, the user obviously achieves important technical advantages.

First of all, the lighting device according to the invention can be associated with any tool equipped with a handle 7, a handle or an extension having a substantially elongated shape, and in any case not necessarily cylindrical.

In other words, the user can freely decide which tool to associate the device 1 with, since the fastening means 6 allow the device 1 to be easily removed from the handle 7 of a tool and to fix it to the handle 7 of a tool. other tool.

Therefore the device 1 is of absolutely universal use in the ambit of a wide range of tools and tools, not only domestic, but also professional, without any limitation.

Furthermore, the characteristic according to which the fastening means 6 comprise an open seat 8 and locking means 9 of the handle 7 inside the seat 8 allows the device 1 to be associated also with a handle 7 which does not have free ends.

Another important technical advantage is constituted by the fact that the device 1 can be fixed to the handle 7 or grip of the tool in the desired position with respect to the work area.

For example, if the device 1 is associated with the handle 7 of a broom, a scrub brush or the like, the restraining means 6 allow the light sources 3 to be advantageously positioned at a desired height from the ground.

Therefore, if you intend to create diffused lighting of a large work area, it may be advisable to position the device 1 along the handle 7 quite high up, that is, close to the normal manual gripping area.

If, on the other hand, it is intended to obtain a more intense and concentrated lighting on a specific work area - for example a limited area of the floor to be cleaned - it may be advisable to position the device 1 along the handle 7 lower.

The user, therefore, can obtain an infinite variety of lighting conditions simply by moving the device 1 along the handle 7, that is, by acting on the restraint means 6.

It should also be noted that the device 1 according to the invention has an extremely simple structure and very economical construction, as it can be built mainly using components already available on the market.

The box-shaped element 2 can be made, for example, of plastic, light and economical. Another embodiment of the device 1 according to the invention is illustrated in the perspective view of figure 5.

In Figure 5 the device is shown with the top surface 19 - or lid - removed for clarity.

The device 1 according to the present embodiment is entirely identical to that of the embodiment of Figures 1-4, but differs in that the actuation means 5 further comprise at least one twilight sensor 25.

The twilight sensor 25 - of the type known per se - is suitable for activating the light sources 3 of the device 1 in the event that the ambient lighting is below a certain threshold, as explained below.

In the illustrated embodiment, the twilight sensor 25 is installed on one of the lateral surfaces 12 of the box-like element 2, but could be provided in other areas of the outer surface of the box-like element 2 itself.

The twilight sensor 25 is operatively associated with the electronic card 21 by means of electrical connections 23 of a known type.

The presence of the twilight sensor 25 in the device 1 allows further important technical advantages to be obtained.

First of all, the electronic control board 21 of the device 1 can be designed in such a way as to allow the activation of the light sources 3 either by means of the button 24, or by means of the twilight sensor 25, independently of each other. In order to optimize the operation of the device 1 provided with the twilight sensor 25, it is also possible to provide a button 24 for activating several positions, for example having a first position associated with the function of light sources 3 always on, and a second position associated with the function switching on of the light sources 3 by means of a twilight sensor 25, as well as a position of sources 3 off.

More in detail, the first position of the button 24 allows to obtain a normal on-off operation of the light sources 3 such as that described in the embodiment of Figures 1-4.

The second position of the button 24, on the other hand, allows to obtain an operating condition in which the light sources 3 are normally off when there is sufficient ambient lighting, that is, it is maintained above a characteristic threshold level. of the twilight sensor 25 used. On the other hand, when the ambient lighting falls below the aforementioned threshold level of the twilight sensor 25, the latter sends a suitable signal to the electronic board 21, which instantly activates the light sources 3.

In the event that, for example, the device 1 is used associated with cleaning tools such as brooms, brushes and the like, this latter situation can occur when, while carrying out the cleaning operations, the user reaches poorly lit areas such as corners hidden by furniture, or in any case poorly lit areas of the room for various reasons.

In all these cases, therefore, the light sources 3, previously switched off to save energy, come on instantaneously and illuminate the work area.

Leaving the poorly lit area, the light sources 3 switch off automatically.

The result is therefore an optimal use of the light sources 3 of the device 1 from the point of view of energy consumption: the sources 3 are in fact activated only when the ambient lighting conditions actually require it. Furthermore, as mentioned, in the transition from normally lit to poorly lit areas and vice versa, the switching on and / or off of the light sources 3 takes place automatically and instantly, without the need for any manual intervention by the user.

Another embodiment of the device 1 according to the invention is illustrated in the perspective view of figure 6.

In Figure 6 the device is shown with the top surface 19 - or lid - removed for clarity.

The device 1 according to the present embodiment is entirely identical to that of the embodiment of figures 1-4, but differs from this in that the means 5 for actuating the light sources 3 comprise a movement sensor 26 .

As better explained below, the motion sensor 26 is suitable for detecting the movement of the tool to which the device 1 is coupled, and for consequently activating the light sources 3.

In the illustrated embodiment, the motion sensor 26 is installed on one of the lateral surfaces 12 of the box-like element 2 and - for example - inside the latter, but it could be provided in other areas of the box-like element 2 itself.

The movement sensor 26 is operationally associated with the electronic board 21 through electrical connections 23.

The motion sensor 26 can be, for example, of the accelerometric type.

The motion sensor 26 of the accelerometric type is of the type known per se, for example it can be of the piezoelectric type or of another type.

More in detail, the motion sensor 26 of the accelerometric type detects the accelerations to which the tool is subjected to which the device 1 according to the invention is associated.

So when the tool, normally stored, is grabbed by the user to be used, the motion sensor 26 immediately detects the acceleration to which it is subjected due to its displacement, and sends a certain signal to the board control electronics 21.

The electronic board 21 then immediately activates the light sources 3.

Also in this embodiment, in order to optimize the operation of the device 1 provided with the movement sensor 26, it is possible to provide a push button 24 for activating several positions, for example having a first position associated with the function of light sources 3 always on, and a second position associated with the switching on function of the sources 3 by means of the signal of the movement sensor 26, in addition to a position of the sources 3 being switched off.

More in detail, the first position of the button 24 allows to obtain a normal on-off operation of the light sources 3 such as that described in the embodiment of Figures 1-4.

The second position, on the other hand, allows to obtain an operating condition in which the light sources 3 are normally off when the tool is stored, and therefore immobile and not subjected to accelerations.

On the other hand, when the tool is moved to be used, the movement sensor 26 sends a suitable signal to the electronic card 21, which instantly activates the light sources 3.

It is also possible to design the electronic control board 21 of the device so that, once the tool has been put away, the light sources 3 are automatically switched off after a certain time interval, for example a few seconds.

Through an appropriate design of these parameters, it is possible to save energy even when, for example, the tool is momentarily abandoned by the user to perform other operations, and is resumed a few moments later.

In fact, in the moments in which the tool is immobile, it is possible to switch off the light sources 3 instantly in order to save energy.

An optimal use of the light sources 3 is thus obtained from the point of view of energy consumption: the sources 3 are in fact activated only when the tool to which the device 1 is associated is actually used by the operator.

Furthermore, as mentioned, in the transition from periods of use to periods of inactivity of the tool, the switching on and / or switching off of the light sources 3 occurs instantly and automatically, without the need for any manual intervention by the user. .

In other embodiments of the device 1 according to the invention, the motion sensor 26 could also be of the infrared type.

In this case, the sensor 26 detects the movement of the tool with respect to the surrounding objects, detecting in particular variations in the infrared radiations emitted by them.

More generally, motion sensors 26 of any other type suitable for rapidly detecting the movements of the tool to which the device 1 is associated can be used.

Another embodiment of the device 1 according to the invention is illustrated in the perspective view of figure 7.

In Figure 7 the device is shown with the top surface 19 - or lid - removed for clarity.

The device 1 according to the present embodiment is entirely identical to that of the embodiment of Figures 1-4, but differs from this in that the means 5 for actuating the light sources 3 comprise both a twilight sensor 25 than a motion sensor 26.

The characteristics and advantages consequent to the use of these sensors 25,26 are the same illustrated in the descriptions of the embodiments of the device according to figures 5,6, but synergistically combined in a single embodiment of the device 1.

In this embodiment, the button 24 for activating the device 1 can therefore have for example four positions, having a first position associated with the function of light sources 3 always on, a second position associated with the function of switching on the sources 3 by means of the signal sent by the movement sensor 26, a third position of ignition of the sources 3 by means of the signal sent by the twilight sensor 25, and a fourth position of sources 3 off.

The user can then choose the operating mode of the device 1 that best suits his needs.

Another embodiment of the device 1 according to the invention is illustrated in figures 8,9.

In this embodiment, the device 1 is functionally identical to those described in the previous embodiments, but has some differences from a constructive and structural point of view.

In this embodiment, the box-like element 2 of the device has a substantially parallelepiped shape, but it could also be of a different shape in relation to specific requirements.

Inside the box-like element 2 are provided all the components described in detail in the embodiment of figures 1-4, and not shown for simplicity in figures 8,9. In particular, an electronic control board 21, power supply means 4 for the light sources 3 housed in a respective compartment 22, electrical connections 23 between the various components, are housed inside the box-like element 2.

On the external surface of the box-like element 2 - in particular on the upper surface 19 - there is a button 24 for activating the light sources 3.

In a completely similar way to what has been described for the previous embodiments, the means 5 for actuating the light sources can further comprise a twilight sensor 25, illustrated in a discontinuous section.

The actuation means 5 may further comprise a motion sensor 26.

The twilight sensor 25 and the movement sensor 26 may both be present, or only one of them may be present.

The button 24 for activating the light sources 3 can therefore be of the type with two or three positions, for example, as described in the previous embodiments.

The means 6 for fastening the device 1 to the handle 7 or grip of the tool comprise an open seat 8.

The seat 8 is provided in an appendix 27 integral with the box-like element 2, for example integral with the rear surface 11 of the box-like element 2.

The appendix 27 is substantially fork-shaped, with the seat 8 in the center for inserting the handle 7 of the tool.

The fastening means 6 also comprise means 9 for locking the handle 7 inside the seat 8.

The locking means 9 are of the elastically resolvable type, and comprise a pair of elastic tabs 28, provided laterally with respect to the seat 8. As illustrated in Figure 9, the tabs 28 are suitable for partially closing the seat 8 and for spreading apart to allow Insertion of the handle 7 of the tool.

Therefore, to fasten the device 1 to the handle 7 of the tool, the user must slightly spread the tabs 28, and insert the handle 7 between the tabs 28 themselves until it comes into contact with the internal surface of the seat 8.

Once inserted, the tabs 28 close elastically and clamp the handle 7 between them.

The reciprocal sliding is prevented by the friction that is created.

To release the device 1 from the handle 7, on the other hand, it is sufficient to slightly force the tabs 28 to spread apart, in order to extract the handle 7 itself from the seat 8.

This embodiment is particularly advantageous from the point of view of the simplicity of installation of the device 1 on a given tool.

In fact, the operations of fastening and releasing the device 1 from the handle 7 are decidedly rapid and easy, and it is not necessary to act on screws or other similar means.

Also in this case the open seat 8 allows the device 1 to be associated with handles 7 even without free ends.

Another embodiment of the device 1 according to the present invention is illustrated in figures 10, 11. The device 1 according to the present embodiment is entirely similar to that shown in figures 8,9, and differs in particular in the shape of the box-like element 2.

In this embodiment, in fact, the box-like element 2 does not have a parallelepiped shape, but has a suitably arched shape so as to orient the light sources 3 provided on it according to a wider range of action.

The light sources 3 can therefore also be, in this case, of the non-orientable type.

The arrangement of the components of the device 1 inside is consequently adapted to the arched shape; in particular, the arrangement of the power supply means 4 and of the electronic card 21 are optimized in relation to the available space.

In particular, the fastening means 6 are identical to those of the embodiment of figures 8,9.

Another embodiment of the device 1 according to the present invention is represented in figures 12,13.

The characteristics of the device 1 of the present embodiment from the point of view of components and operation are exactly the same as the previous embodiments, and therefore will not be repeated in detail.

However, the device 1 has some differences from the constructive and structural point of view.

The box-like element 2 has, in this embodiment, an extended central opening 29.

The box-like element 2 has a shape which, in plan view, is substantially similar to a letter â € œDâ €, consisting of a substantially parallelepiped portion 30 and an arched portion 31 connected to each other.

All the main components are preferably housed in the parallelepiped portion 30, which presents greater availability of internal space.

The constraint means 6 of the handle 7 of the tool comprise an open seat 8, provided inside the central opening 29.

In particular, the seat 8 is provided in correspondence with the internal surface of the arched portion 31.

The fastening means 6 also comprise means 9 for locking the handle 7 inside the seat 8.

The locking means 9 are of the elastically resolvable type, and comprise a pair of elastic tabs 28, provided on the sides of the seat 8.

As shown in Figure 13, the tabs 28 are adapted to partially close the seat 8 and to spread apart to allow the insertion of the handle 7 of the tool.

The tabs 28 are, for example, of an arcuate shape with the convex faces facing the seat 8, so as to allow easier insertion of the handle 7 into the seat, and an easier release of the same.

Therefore, to fasten the device 1 to the handle 7 of the tool, the user must first insert the device 1 along the handle 7 at one of its free ends.

He must then slightly spread the tabs 28, and insert the handle 7 between the same tabs 28 until it comes into contact with the internal surface of the seat 8.

Once inserted, the tongues 28 close elastically and clamp the handle 7 between them. The reciprocal sliding is prevented by the friction that is created.

To release the device 1 from the handle 7, on the other hand, it is sufficient to slightly force the tabs 28 to spread apart, in order to extract the handle 7 itself from the seat 8, and then remove the device 1 from the handle 7 at one of its free ends. .

This embodiment is also particularly advantageous from the point of view of the simplicity of installation of the device 1 on a given tool.

In fact, the operations of fastening and releasing the device 1 from the handle 7 are decidedly rapid and easy, and it is not necessary to act on screws or other similar means.

The particular arched shape of the tongues 28 allows to carry out the locking and release operations even with one hand only, without having to open the tongues 28 themselves manually to insert the handle 7.

Another embodiment of the device 1 according to the invention is illustrated in figures 14,15.

The characteristics of the device 1 of the present embodiment from the point of view of components and operation are exactly the same as the previous embodiments, and therefore will not be repeated in detail.

On the other hand, the shape of the box-like element 2 and that of the fastening means 6 are different.

The box-like element 2 in fact has a discoidal shape, with the light sources 3 provided along a portion of the lateral surface.

Obviously any number of light sources 3 can be provided.

For example, in this embodiment five light sources 3 are provided, arranged angularly equidistant from each other with respect to the center of the box-like element 2.

The fastening means 6 to the handle 7 of the tool comprise a closed seat 8.

The seat 8 consists of a through opening made in the box element 2.

The seat 8 is preferably cylindrical in shape, but it could also be of another shape.

The seat 8 can be positioned eccentrically with respect to the center of the box-like element 2, in order to optimize the space available for the assembly of the various components of the device 1.

The fastening means 6 also comprise means 9 for locking the handle 7 of the tool inside the seat 8.

The aforesaid said locking means 9 comprise an elastically yielding annular element 32, inserted within the seat 8, so as to completely or even partially cover its internal surface.

The annular element 32 is adapted to surround the external surface of the handle 7 of the tool.

For example, the annular element 32 can be made of rubber or other similar soft material.

The annular element yields elastically in a radial direction upon insertion of the end of the handle 7, but still keeps the device 1 stably in the desired position along the handle 7 itself.

The present embodiment of the device 1 is particularly convenient and easy to use in the case of use with tools with handle 7 having a free end, such as a broom, a scrub brush, or the like.

In fact, the handle 7 is simply inserted into the seat 8, and the device 1 is moved along the handle 7 itself to the desired position by exerting a slight pressure to overcome the resistance opposed by the annular element 32.

Another embodiment of the device 1 according to the invention is illustrated in figures 16,17.

The characteristics of the device 1 of the present embodiment from the point of view of components and operation are exactly the same as the previous embodiments, and therefore will not be repeated in detail.

On the other hand, the shape of the box-like element 2 and of the fastening means 6 are still different.

Also in this embodiment the box-like element 2 has a substantially discoidal shape.

The light sources 3 are distributed along the lateral surface of the box-like element 2.

There are six light sources 3, distributed angularly equidistant with respect to the center of the box-like element 2 in two groups of three, so as to identify a front and a rear part of the device 1.

This allows to obtain a more complete illumination of the work area: for example, in the case of using device 1 with a cleaning tool such as a broom or mop, it is very useful to be able to illuminate both the front area and the area. back of the tool during its typical reciprocating movement.

The fastening means 6 to the handle 7 of the tool comprise a closed seat 8.

The seat 8 consists of a through opening made in the box-like element 2, for example in correspondence with the center of the same.

The seat 8 is preferably cylindrical in shape, but it could also be of another shape.

The fastening means 6 also comprise means 9 for locking the handle 7 of the tool inside the seat 8.

The aforesaid locking means 9 comprise at least one screw or pin 33 inserted in a respective through hole 34 provided in the box-like element 2, and which intercepts the seat 8.

The screw or pin 33 comprises an end 35 adapted to abut on the external surface of the handle 7, for locking inside the seat 8, as illustrated in figure 17.

Also this embodiment of the device 1 is particularly convenient and easy to use in the case in which it is used with tools with handle 7 having a free end, such as a broom, a scrub brush, or the like.

In fact, the handle 7 is simply inserted into the seat 8, and the device 1 is moved along the handle 7 itself to the desired position; the device 1 is then locked in the aforesaid position by manually acting on the head 33a of the screw or pin 33.

Another embodiment of the device 1 according to the present invention is illustrated in figures 18,19.

The characteristics of the device 1 of the present embodiment from the point of view of components and operation are exactly the same as the previous embodiments, and therefore will not be described again.

According to this embodiment, the device 1 has been developed in particular to be used with cleaning tools such as brooms, brushes and the like, as will become clearer hereinafter.

The box-like element 2 of the device comprises a central portion 36 in which the means 6 for fastening to the handle 7 of the tool are provided, and two lateral portions 37 which mirror each other.

The main components of the device 1 are provided inside the side portions 37, which have greater internal space.

The lateral portions 37 have a preferably elongated conformation, so as to substantially trace the shape of a normal broom or scrub brush.

In the embodiment shown, the light sources 3 are a total of twelve, six for each side portion 37.

Within each side portion 37, the light sources 3 are divided into two groups of three, one front and one rear.

Therefore, even in this embodiment, the lighting of the work area is complete on two sides.

The box-like element 2 according to the present embodiment is particularly suitable for being placed directly on the upper surface of a normal broom or scrub brush.

The fastening means 6 can therefore comprise only a seat 8 for inserting the handle 7 of the tool.

As illustrated in the figures, the seat 8 has a cylindrical internal surface, but it could also have another shape.

If necessary, the fastening means 6 can also comprise means 9 for locking the handle 7 inside the seat 8, mainly for adapting to handles 7 of different diameters in order to avoid rotation of the box-like element 2 with respect to the tool, or if you still want to position the device 1 at the desired height with respect to the handle 7.

The locking means 9 can comprise, for example, an annular element made of elastically yielding material, inserted inside the seat 8 so as to completely or even partially cover its internal surface.

This embodiment of the device 1 guarantees the best results from the point of view of the illumination of the work area, thanks to the high number of light sources 3 and their distribution along large surfaces.

Another embodiment of the device 1 according to the present invention is illustrated in figures 20-23.

In this embodiment, the device comprises a pair of identical box-like elements 2, able to be fastened to the same handle 7.

More in detail, the box-shaped elements 2 are able to be fastened to the same handle 7 in a configuration of minimum bulk, or as an alternative to the separate handles 7 of two tools.

As will become clearer below, this embodiment has been specifically developed to offer a versatile solution in situations where it may be necessary to use two tools at the same time.

For example, in the case of floor cleaning, these tools can consist of a broom and a dustpan to collect the garbage.

Figures 20,21 illustrate the device 1 in the configuration of minimum bulk, in which both of the box-like elements 2 that make it up are intended to be associated with the handle 7 of the same tool.

In figures 22,23, on the other hand, the two box-like elements 2 are separate and therefore intended to be associated with the handles 7 of two distinct tools.

Each of the box-like elements 2 is substantially shaped like a semi-disc.

The constraint means 6 are provided at the center of the half-disc; they include a closed seat 8 for inserting the handle.

The seat 8 has a cylindrical or substantially cylindrical surface and, as shown in particular in Figure 22, affects only a portion of the height of the box-like element 2.

The fastening means 6 also comprise, for each of the box-like elements 2, locking means 9 of the handle 7 inside the seat 8.

The aforesaid locking means 9 comprise at least one screw or pin 33 inserted in a respective through hole 34 provided in the box-like element 2, and which intercepts the seat 8.

The screw or pin 33 comprises an end 34 adapted to abut on the external surface of the handle 7 of the tool for locking inside the seat 8, as illustrated in figure 23.

Each of the box-like elements 2 of which the device 1 is composed also comprises a recess 38 for housing the seat 8 and the locking means 9 of the other box-like element 2, in the configuration of minimum bulk represented in figures 20,21. As can be seen better in figure 22, the recess 38 of each box-like element 2 preferably has such a shape and size as to allow the user to manually act on the locking means 9 in a sufficiently easy way, even when the two box-like elements 2 are associated with the same handle 7 in the configuration of minimum bulk.

Thanks to this solution, therefore, the user can choose whether to use the device 1 associated with a single handle 7 of a tool, or associated with two handles 7 of two distinct tools.

In the first case, the device 1 is presented in the configuration of figures 20, 21: two opposing groups of light sources 3 are therefore available on the same device 1 which can illuminate both the work area in front of the tool and the one which is located behind the tool.

The two distinct groups of light sources 3 located on the two box-like elements 2 can naturally be operated independently of each other.

If their operation is set in such a way as to activate the light sources 3 by means of the twilight sensor 25 or by means of the motion sensor 26, if present, the simultaneous switching on / off of both groups of light sources 3 is obtained instead, in the manner described for the previous forms of implementation.

In the second case, the device 1 appears instead in the configuration of figures 22,23.

In this configuration, each of the two tools can therefore illuminate its own distinct work area, in relation to the specific needs of use, in the same operating phase performed by one or more users.

The passage from one configuration to another is, as mentioned, very simple, quick and easy for any user.

In other embodiments of the device according to the invention, the fastening means 6 could also be of the Velcro ® type, of the self-adhesive type, of the magnet type, and the like.

The device according to the invention could also be connected to parts of the tool other than the handle 7, for example by means of interlocking, screw, Velcro ®, or other equivalent means of quick attachment and detachment.

We have thus seen how the invention achieves the proposed aims.

The present invention has been described according to preferred embodiments, but equivalent variants can be conceived without departing from the scope of protection offered by the following claims.
