Description

Signaling device The invention concents a signaling device, including one or several light sources 6 powered by a battery pack.

This type of device Is used to ensure that information is transmitted to a person located near the device, and in particular to signal a hazard to that person, such as a work zone, tlie presence of a vehicle, an obstacle, etc.

The light emitted by die device can itself carry the information to be transmitted, for W example when the light sources are tri-color lights; in another embodiment, the signaling device is used ίο light a signaling clement, such as a road sign, and that road sign bears the information to be transmitted.

The term ‘battery pack’ is used broadly in this document to designate any transportable equipment for storing electrical energy, rechargeable or not. R can thus include in particular one or several energy storage cells (rechargeable) and/or one or several battery cell s (not rechargeable).

Tliis family of signaling devices includes in particular warning lights, for example blinking or color-changing, used for road signaling in the form of signs or marker posts. in general, such a signaling device includes a battery pack, at least one light source 20 capable of being electrically powered by the battery pack, at least one protective housing, among which a housing called a control housing contains means for control and/or distribution of the electric current supplied by the bLittery pack to said at least one light source, and means for electrically connecting the battery pack to said control and/or distribution means, The light source can be a flashing light including a bulb or LEDs (light-emitting diodes), generally associated with reflectors in the form of parabolic mirrors, serving to direct the emitted light in the desired direction.

The protective housing is a housing serving to protect an element (or a portion of an element) situated in the bousing from outside attacks. This may for example be a housing sheltering a light source.

Such a device is generally used outside. Thus, the protective houshig(s) serve in particular to protect the components of the signaling device against bad weather.

The control housing generally primarily includes an electronic card arranged in a protective housing.

In a known manner, the light sources included by the signaling device can be powered by a battery arranged inside a protective housing. This protective housing is then often provided to contain both the control housing and the battery pack.

Once the battery pack is dead, H must be recharged or replaced, by removing the dead battery pack and replacing it with another, duly charged battery pack. Since the battery pack is inside the protective housing, it is necessary to open the latter, disconnect the battery pack, remove it from the housing, and perform these steps in reverse with the now battery pack.

Opening die housing requires time and attention from the operator responsible for replacing the battery pack; sometimes, he also needs to tisc tools to open the housing and/or connect or disconnect the battery pack. Par example, if the battery pack has terminals, disconnecting the batLery pack generally requires a key.

The signaling device of the type previously described is used in particular for road signaling, h is understood that once the battery pack is disconnected, the signaling device no longer lights up. Thus, if the signaling device is used to signal a hazardous area, for example a work site or a detour, it is essential for the period during which the device docs not light up to be minimized.

A first aim of the present invention is Co propose a signaling assembly, including at least one signaling device of the type presented above, allowing replacement of the battery pack in a very short amount of time, while also allowing the battery pack to be located in the immediate vicinity of the light source(s) it powers, 'Phis aim is achieved owing to the Fact the signaling assembly further includes at least One piece of road signaling equipment or a mast, supporting said device; and fastening means for reversibly fastening the battery pack in a fixed position in relation to the control and/or distribution means, through cooperation of shapes, on one of said at least one protective housings called support housing, or on said at least one piece of signaling equipment, said fastening means being such that the fastening of the battery pack using said means causes the electric connection of said battery pack to the control and/or distribution means, and that the battery pack is connected to said control and/or distribution means while being located outside all of said at least one protective housings and without it being necessary either to open or to close a protective housing, a part of connection means for making the connection with the battery pack being located outside or at least being accessible from the outside of said at least One protective housings,, One understands that the battery pack can dins be connected while being outside the housings of the signaling device, Since the pan of the connection means used to make the connection with the battery pack is located outside or at least accessible from the outside of the protective ho u si ng (s), it is not necessary to open and close the protective housing to recover the dead battery pack or to place a charged battery pack there. All of the operations for replacing the battery pack are done outside the housing(s), The term ‘part of the connection means used to make the connection with the battery packh here designates the parts of the connection means whereof the relative movement makes it possible to open/close an electric contact and thus connect os- disconnect the battery pack from I he control and/or distribution means. This may for instance involve male and female parts of an electrical plug.

The battery pack is chosen as a function of the outside environment to which it is exposed, ft may thus be necessary for it to have a reinforced outer shell that can resist bad weather, .such as rain or snow, as well as any shocks, etc.

No housing of the device being called on to contain the battery pack, which is often relatively bulky, the invention makes it possible to reduce the dimensions of the protective housings of the signaling device. Thus, the volume of the device is reduced, which makes it easier to store, {There can he only a single protective housing in the device.) Furthermore, with the invention the control housing is no longer opened and closed each time the battery pack ij> replaced. The sealing (or watertightness) of the control hoiking is therefore greatly improved in relation to devices in which the battery js arranged within the control housing itself, in the immediate vicinity of the electronic control and/or electrical current distribution cards.

Lastly, one will note that the invention is also applicable to signaling devices including several control and/or electrical current distribution housings. According to the invention, the bat Lory pack i,s connected while remaining outside these different housings.

In one embodiment, the connection means include an electric outlet arranged on a surface of the battery pack or on a cable permanently connected to the battery pack. This electrical outlet can be arranged on an outer surface of the battery pack. Tt can also be arranged in an loiter compartment of the battery pack, provided to be opened only when Lite battery pack is connected. Naturally, like the battery pack, the type of outlet (and/or cable) is chosen as a function of the outside environment to which Lhe batLery pack is exposed, depending for example on bad weather, any shocks, etc.

In one embodiment of the device, a light source is fixed on the control housing, 'this configuration allows a very compact realization of the signaling device, This configuration is particularly interesting when the battery pack is also fixed on the control housing.

One will noLe that in this document, the expression 4 A is fixed on B' means in particular by A is mechanically supported by B, and furthermore implicitly that A is directly fastened on B, i.e. Lite essential function of the means for fastening A on B (other than A and B) is Lo fasten A oil 13: this can be screws, glue, but for example a signaling clement, the main function of which is something other than fastening A on B.

In one embodiment of the device, a light source includes a front surface, and the device also includes a cap that can be forcibly mounted in a groove formed in that surface.

Naturally, in general the groove is formed on the periphery of the front surface of the light source.

In the case where the battery pack must be fastened to be kept fixed in relation to tbe control and/or distribution means, in one embodiment the battery pack is fastened on a one of said protective housings, called support ho lea i ng.

In relation to a fastening method in which the battery pack is fastened on a support 5 outside the signaling device, this fastening mode makes it possible to eliminate an interface between the signaling device and the support.. Such an elimination is interesting because the characteristics of the support arc often variable, poorly known, which makes Che quality of the fastening of the batteiy pack on the support random; it can also be quite a bit faster to fasten the battery pack on the support housing than on the support itself, because the support housing can be designed precisely with a simple and quick fastening of the battery pack in mind.

In particular, in one advantageous embodiment, the support housing is the control housing. The distance is then minimal for the electric connection between the battery pack and the control housing. The support housing can also be, as a non-exclusive alternative, a protective housing of a light source.

The part of tbe connection means of the battery pack allowing the connection of the battery pack should then be outside the support housing, or at (cast accessible from the outside thereof, in order to allow the connection to the control housing without opening Che housing.

Faittening the battery pack on the control housing is one particularly interesting embodiment. The control housing is an important element in a signaling device of tire type of the invention. Although it generally occupies a fairly small volume, it can be strengthened (if necessary) and arranged so as Lo allow the fastening of the battery pack, In tbe case where the signaling assembly includes signaling equipment, the device is generally connected to the equipment and .serves to draw attention Lo that equipment.

The signaling assembly includes means for fastening the battery pack, making it possible to fasten the battery pack and keep it in a fixed position in relation to the control and/or distribution means.

Different solutions can be used to fasten the battery pack, As previously presented, in one embodiment, the battery pack is fastened on the support or on the signaling equipment. The control housing, like the assembly of the protective housings, is then freed front the ioad that is the battery pack.

In an alternative solution, the battery pack is fastened on a protective housing, called support housing, In this case, in one embodiment the support housing has a lower portion in which fastening means are arranged, using which the support housing is fastened on the support or the signaling equipment, Advantageously, it is thus possible for a light source to be arranged on a front face (i.e. a face provided to he oriented toward a person to whom the device transmits information) of the support housing, the battery pack being able to be fastened on a rear surface of the support housing. 'Hie upper portion of the support housing is available for fastening not only of the battery pack, bitt of other elements such as one or several light sources, In one embodiment of the signaling assembly, a double-sided ad Erosive tape is used to fasten a protective housing. This fastening method can also be used for the support housing serving as support for the battery pack if needed, Γη addition, the battery pack is re vers i bly fastened through cooperation of shapes, The term ‘reversibly fastened* means that the battery pack can be fastened, but can then be disassembled so that it can be recharged or replaced.

The arrangement of the control housing and the battery pack wiLh a cooperation of .shapes advantageously makes it possible to avoid using additional parts to fasten the battery pack on the control housing, and to perform that fastening economically, simply and reliably. The battery pack may be maintained particularly under the effect of its weight; it may be locked in position by ratchet or anti-return locking means, allowing its positioning and placement, in one embodiment, the signaling assembly comprises a signaling sign as signaling equipment; said sign has an essentially planar front face on which information to be transmitted appears in a forward direction; said sign has a rear face on a side of the sign opposite the front face, on which eompOEtents of the signaling device am fastened; in the absence of Lhe battery pack, among said components fixed on the rear face of the sign, tbe three thickest components in the rear direction have essentially equal thicknesses in the rear direction of the sign, to favor the stacking of several signs of the same type on top of each other.

In one embodiment, the battery pack is fastened by fastening means so as to be kept in a fixed position in relation to the contJO 1 and/or distribution means, and these fastening means are such that the fastening of the battery block using said means causes (or involves) the electrical connection of said battery pack to the control and/or distribution means, In other words, when Lhe battery pack is fastened using fastening means, the battery pack is necessarily electrically connected to the control and/or distribution means, Mechanical fastening and electrical connection are done connectedly and simultaneously, in a single operation oi' a single movement. This .simplifies·} and accelerates the replace me tit of a battery pack when it is used or dead.

The invention lastly also applies to wheeled equipment, including a signaling assembly as previously presented, This equipment can for example be a trailer; a vehicle, in particular a worksite vehicle, etc. Λ second aim of the invention is to propose a method for changing a battery pack of a signaling device, said equipment including at least one light source powered by a used battery pack needing to be replaced, and at least one protective housing, including a control housing containing control and/or distribution means for the electrical current supplied by the battery pack to said al least one light source; method that allows Lhe battery pack to be replaced quickly.

The term ‘used battery pack' here refers to a battery that is at least partially drained, and which smist be replaced to make it possible to have a charged batLcry pack in its place, capable of supplying the desired current.

This aim is achieved owing to the fact that the method includes the following steps: a) the used battery pack being located outside the assembly of the protective housings and connected to said control and/or distribution means, one disconnects it from said control and/or distribution means; b) the used battery pack is detached from the other components of the device; c) a charged battery pack able to replace die used battery pack is provided; and d) the charged battery pack is fastened in die place previously occupied by the used baLLery pack, and the charged battery pack is connected to she control and/or distribution means.

Thus, the battery pack is exchanged without having to open any bousing, it is thus W quick, which limits the risk incurred by the operator responsible for making the switch. hi one embodiment, in step b), the operation for fastening the charged battery pack causes the electric connection thereof In other words, die movements carried out to fasten the charged battery pack necessarily lead to electrically connecting the charged battery pack to the control housing.

The invention will be better understood and its advantages will better appear upon reading the following detailed description of embodiments illustrated non-limitingly, rfhe description refers to the appended drawings, in which: - figure 1 is a diagrammatic view of a signaling assembly comprising a signaling device in a first embodiment; - figure 2 is a diagrammatic view of a signaling device in a second embodiment; - figure 3 is a diagrammatic view of a signaling assembly comprising the device of figure 2, mounted on a mast; - figure 4 is a diagrammatic side view of the assembly shown in figure 3; - figure 5 is a partial diagrammatic side view of an embodiment of a signaling assembly accoiriing to the invention, in a third embodiment; - figure 6 is a partial diagrammatic side view of an embodiment of a signaling assembly according to tire invention, in a fourth embodiment.

Figure 1 shows a first embodiment of a signaling assembly 100, The signaling assembly 100 includes a sign 10, winch is a triangular mad signal sign, and a signaling device 20, The device 20 includes a battery pack 22, three Light sources 24, 26, 28, a control housing 30, containing means 32 for controlling and distributing the electrical current provided by the battery pack 22 to the light sources 24, 26, 28.

These means 32 for controlling and/or distributing the electric current essentially consist of an electronic card shown by dotted lines, and are connected by cables 34, 36, 38 to the light sources, The device 20 also includes electrical connection means 40 that make it possible to connect the battery pack 22 to the control housing 30, In this embodiment, these electrical connection means 40 consist of a cable 42, permanently connected to the control housing 30, and ending at tlieir free end outside die housing 30 with a male plug 44. The battery pack 22 includes a socket 46 that allows die connection between the control housing and the battery pack 22, The battery pack also includes a carrying handle 48. The control housing 30 is provided to be fastened on a rear face of the sign 10 using two sections of double-sided adhesive tape 50, 'fhe face of the sign 10 not visible in figure 1 includes signaling marking, This is the face intended to be seen, and it defines the front direction A of the signaling device. lhe rear face of the signaling .sign 10 is toe face Lhat is on the side opposite the front 10 face of the sign. The rear direction is symbolized by arrow B.

All of toe components of the signaling device 20 are arranged on the real1 side of the sign 10. The front and rear faces of the sign 10 are essentially planar', with toe exception of a rim 52 going around the sign 10.

Each of the components of the signaling device 20 fastened on the rear face of the sign 15 10 has a certain thickness in the rear direction B in relation to the rear face of toe sign. In the presented embodiment, the tltree light sources 24, 26 and 28 have the greatest thickness (H) in the rear direction (B). Inversely, the control housing 30 has a thickness ΓΓ along direction B smaller than the thickness H of toe light sources.

Owing to to is, when several signaling assemblies 100 are stacked on top of each other, 20 the light sources (26) and signs (10) support toe weight of the assembly of the signs placed above, The control housing does not hear the weight of these signs. Owing to this arrangement, signaling assemblies 100 can be stacked stably.

Figure 2 shows a signaling device 220 in a different embodiment hunt that presented in figure t. Tills device 220 includes certain elements identical or nearly identical to the corresponding elements of the device 20 of figure 1; for this reason, toe numerical references assigned to these elements are kept in toe description that follows.

The device 220 thus comprises a battery pack 22 and a control housing 30 essentially identical to those that are part of the device 20 of figure 1. One thus sees that the arrangement of the battery pack 22 and the control housing 30 allows the use of these in a configurable way, and allows them to be integrated into different signaling devices.

The only difference is in toe arraugement of toe means for electrically connecting the battery pack 22 on toe control housing 30. In toe arrangement of figure 2t the cable 252 is permanently fastened to tire battery pack; it has a plug on its end provided to be connected to a complementary plug of toe control housing 30. This complementary plug is situated on a lower external face of the control housing 30, and is accessible from the outside of that housing.

The device 220 also comprises a single light source 224, fastened on a front face 230 of toe control housing 30 using four screws 234, Tins front face 230 is arranged on toe front side of the control housing 30, foe front direction A2 being the direction in which the Ii gilt source 224 lights up.

The light, source 224 includes a set of LEDs 226 that are contained in a housing 228, This housing is closed on all sides, with the exception of the front face 232 of the light source 224, Tlie battery pack 22 is fastened on the control housing 30 as follows, Tire upper portion of the control bousing includes a first set of support surfaces 242 which extend on two vertical lateral sides and on tlie upper side of die control housing 30, Behind the surfaces 242, the control housing 30 also includes a shoulder 249 having support surfaces 244. The shoulder 249 extends toward the sides and the cop of the control housing 30.

Lastly, the rear (planar) face of the control housing 30 is provided to be in contact with tlie front face 241 of the battery pack.

Moreover, the battery pack 22 lias the general shape of a parallelepiped rectangle. In its upper portion, a fastening block 243, also of essentially parallelepiped shape, is formed on the front face 241 of die battery pack.

This block 243 is provided primarily to allow die fastening of the battery pack 22 on the control housing 30. For this, a recess 245 is formed In the middle of the lower face of the block 243, This recess 245 includes a first set of support surfaces 246 provided to cooperate with tlie corresponding support surfaces 242 of the control housing, and a groove 247 whereof die surfaces are provided to cooperate with the surfaces 244 of the shoulder 249.

The cooperation of tlie shapes of the different surfaces specified above keep the battery pack in position in relation to the control housing 30.

For safety reasons, the device 220 also includes means for locking the battery pack in 25 position on tlie control housing.

Indeed, at the top of the front face 230, the control housing 30 extends by an elastic tab 236, The upper portion of said clastic tab 236 includes a retaining lug 23S that extends toward the rear cf the tab. The elastic tab mid its lug 23S serve to prevent the battery pack from moving toward the top of the control housing.

Tie battery pack 22 is fastened on the control housing 30 as follows: the battery pack 22, held by its handle 48, is approached from the rear (in relation to the front direction A2) of foe control housing 30 by moving it from the rear toward tlie front.

During that movement, the battery pack 22 is kept at a height slightly higher than tlie height at which it is provided to be mounted.

The battery pack then comes into contact with the tab 236. To fasten foe battery pack 22, one then causes it to descend in vertical translation, until it is placed in its final mounting position. In this position, foe retaining lug 238 passes above tlie upper face 240 of the battery pack and prevents foe latter from coming out of the control housing 30.

The battery pack 22 is then kept in position, not only by the retainuig lug 238 associated with the flexible tab 236, blit above all by the cooperation of shapes occurring between the upper surfaces of the control housing 30 and the corresponding surfaces of the battery pack 22.

Naturally, in general a number of complementary shapes can be chosen to ensure the fastening of die battery pack 22 on the control bousing 30.

Once die battery pack is fastened on the control housing 30, the placement of the battery pack is completed by simply electrically connecting the battery pack with lhe means for control and distribution of the electrical current 32 contained in the control housing 30.

This is done simply by connecting the cable 42 on the outlet 36 of lhe battery pack.

Inversely, to remove the battery pack, one need only disconnect it (disconnect the cable 42), then take it out of the control housing, by pushing the elastic tab 236, then lifting the battery pack, As one sees, tJie positioning and placement operations of die battery pack can be done 15 in j us t a few seconds.

Figure 3 shows a signaling assembly in which the signaling device 220 Illustrated in figure 2 is integrated.

One first notes that the device 220 has been completed by the addition of a cap 302. A cap is a typically opaque cover, serving to at least partially prevent the front surface of the light source from being exposed to the sun’s ray.% in order to increase the visibility of the lighting emitted by the light source.

The cap 302 is simply formed in a portion of elastic planar sheet metal, cut to the desired dimensions. The cap 302 can be made from any material, for exiimple plastic or metal, It is fastened on the front surface 232 of the light source 224 while being forcibly mounted in a groove 304 formed in the front face 232. The mounting is therefore done very simply by forcibly curving the cap 302 and inserting it into die groove 304, When the cap 302 is released, it remains naturally fixed under the effect of its own elasticity.

The signaling assembly 300 also includes a vertical mast 306 at die top of which die device 220 is fixed.

Lastly, the assembly 300 includes signaling equipment, ire. a triangular signaling sign 308. The signaling device 220 is fastened on the mast 306 using a flange 310, To enable this fastening, the control housing 30 includes a lower portion 312 whereof the front face 314 in the front direction A3 of die signaling assembly is essentially planar. The flange 310 assume the form of a partial hose clamp, which goes partially around the mast 306 and is fastened on either side of the mast on the front face 314 of the lower portion 312 of the control housing, using two screws 316. Thus, when the mast 306 is gripped between the flange and the control housing, the device 220 is perfectly fixed thereon.

As shown by figures 3 and 4, the device 220 is mainly situated above the upper end 318 of the mast 306. Owing to this, the device 220 can include a battery pack 22 arranged on its rear side, while having the ability to light toward the front (light source 224).

One notes in particular in figure 4 that the support of tire signaling device 220 and the 5 sign 308 includes not only the mast 306, but also a trolley 320 having wide coverage, heavy enough to avoid any tipping of the assembly 300. Owing to this trolley, the signaling assembly 300 is wheeled equipment, easily movable.

Figure 5 shows, in a third embodiment, certain elements of a signaling device according to the invention.

This device 520 includes a control housing 530 containing means for control and distribution of the electric current, and a battery pack 522 that is, with the exception of electrical connection means between the battery pack 552 and the means for control and distribution of the device 520, essentially identical to the battery pack 22 previously presented. δ The control housing 530 is fastened on a mast 509.

The battery pack is not fastened on said mast 509, but on the rear of a solid signaling sign 508, itself fastened on the mast 509.

To allow the fastening of the battery pack on the sign 508, the 5 device 520 includes a support clement 510, stuck using double-sided adhesive tape, on the rear face of the sign 508.

The battery pack 522 is fastened on the sign 508 via die support element 510.

The outer shape of the lateral, upper and rear parts of the support element 510 is identical to the corresponding shapes of the control housing 30 previously described. Thus, the support element allows the· fastening of the battery pack 22 through lhe same cooperation of shapes as in the device 20.

The battery pack 522 is aiso connected to the control and distribution means of the device 520. fn tills aim, die support element 510 is permanently electrically connected to die means for control and distribution of the electric current of the signaling device 520 by a control housing 530 via a cable 514.

Furthermore, the battery pack 522 (in mounting position) is electrically connected with the support element 510. This connection is done as follows: Arranged on die upper portion of the support element 51.0 are male connection terminals 544, which protrude outside the support clement 510. The battery pack 522 includes a socket 546 that is positioned so as to allow the connection of the male terminals 544 in the socket 546 when the battery pack 522 is fastened on the support element 510.

Advantageously, no movement specific to the electrical connection is needed to perform the electric connection of the battery pack 522 to the control and distribution means of the device 520: one need only fasten the battery pack 522 on the support element 510 for the electrical connection to be done, because the engagement of the battery pack 522 on the corresponding shapes of die support element 510 leads ipso facto to the connection of the male terminals 544 cn tlie socket 546, Figure 6 shows another possible embodiment of a signaling device. In this embodiment, the battery pack 522 is fastened on a rear face of the housing 628 of a light source 624.

As for the support element 51C, die shapes of the lateral, upper and rear' faces of the rear portion 605 of the housing 628 are identical to those of the control housing 30 previously described. As a result, a battery pack of the type of the battery pack 22 previously described is fastened through cooperation of shapes on die protective housing 628 through the same cooperation of shapes as in the device 20.

The housing 62S also has a vertical planar lower portion 612, on which a flange 610 is fastened. The flange 610 grips the upper end of a mast 606 on the lower portion 612, such that tiie light source 624 (the battery pack being fastened thereon) is fastened on die mast 606. s The other components of the control device are contained in the control housing 630, also fastened by flange on the mast 606.

The housing 628 is permanently electrically connected to the control housing 630 by a cable 614.
