Description

  

  Installation d'éclairage et de signalisation, notamment pour véhicule automobile    Le brevet principal a pour objet une ins  tallation d'éclairage et de signalisation, notam  ment pour véhicule automobile, comprenant  une source de courant électrique destinée<B>à</B>  l'alimentation des feux de position (feux de po  lice<B>y</B> compris les feux arrière), des phares et  des feux de croisement au moins, -un commu  tateur<B>à</B> main<B>à</B> trois positions correspondant,  respectivement-, la première<B>à</B> la circulation de  jour, la source de courant étant susceptible  d'alimenter certains appareils électriques du  véhicule et notamment l'avertisseur acoustique,  la seconde<B>à</B> la circulation de nuit dans les ag  glomérations, la source de courant alimentant,  en plus des appareils alimentés en première po  sition,

   les feux de position (feux de police<B>y</B>  compris les feux arrière), la troisième position  correspondant<B>à</B> la circulation de nuit hors des  agglomérations, la source de courant alimentant  en plus des feux arrière, soit les phares, soit les  feux de croisement (code), un commutateur<B>à</B>  commande<B>à</B> pied étant inséré dans le circuit  pour permettre la sélection des phares, soit des  feux de croisement (code), ce commutateur<B>à</B>  pied comprenant au moins un contact supplé  mentaire permettant la sélection au pied d'un  organe de signalisation même lorsque le com  mutateur<B>à</B> main est en seconde position.  



  Dans la forme d'exécution décrite dans le  brevet principal, ce contact supplémentaire est  du type<B>à</B> rappel élastique en position ouverte    et actionné au début de la course du bouton  de     man#uvre    du commutateur<B>à</B> pied. Dans  cette forme d'exécution, il était toujours pos  sible d'actionner l'avertisseur acoustique en  pressant<B>à</B> fond sur le commutateur<B>à</B> pied, ce  qui peut être un inconvénient dans certains cas,  car il est possible que le conducteur appuie  trop fort sur le contacteur pour passer des  grands phares aux feux de croisement, et qu'il  actionne ainsi inopportunément son avertis  seur acoustique.  



  La présente invention vise<B>à</B> remédier<B>à</B>  cet inconvénient grâce au fait que ledit con  tact supplémentaire est prévu pour relier trois  bornes électriquement entre elles lorsqu'il est  actionné, ces bornes étant respectivement re  liées<B>à</B> l'alimentation des feux de position,<B>à</B>  l'alimentation d'un des feux de route (codes ou  phares) et<B>à</B> une borne d'un avertisseur acous  tique dont     Pautre    borne est reliée<B>à</B> la source  de courant du véhicule pour les trois positions  du commutateur<B>à</B> main.  



  Le dessin annexé représente, schématique  ment et<B>à</B> titre d'exemple, une forme d'exécu  tion de l'objet de l'invention.    La     fig.   <B>1</B> en est le schéma électrique<B>;</B>    la     fig.    2 représente le commutateur<B>à</B> pied  utilisé dans cette forme      & exécution,    son cou  vercle étant enlevé<B>;</B>      la     fig.   <B>3</B> est une coupe<B>à</B> travers le com  mutateur selon la     fig.    2.  



  L'installation d'éclairage et de signalisation  comprend une source de courant électrique,  par exemple une batterie d'accumulateurs<B>1,</B>  'destinée<B>à</B> alimenter des feux de position (feux  de police), des phares et des feux de croise  ment au moins.    Un commutateur<B>à</B> main 2<B>à</B> trois positions  est prévu pour la sélection des différents ap  pareils<B>à</B> alimenter pour la circulation de jour  et de nuit.

   La position I du commutateur 2  correspond<B>à</B> la circulation de jour, la source  de courant<B>1</B> étant susceptible d'alimenter cer  tains appareils électriques du véhicule et     no-          tament    l'avertisseur acoustique<B>3.</B> La position  II correspond<B>à</B> la circulation de nuit dans les  agglomérations, la source de courant<B>1</B> ali  mentant, en plus des appareils alimentés en po  sition I, les feux de position 4 (feux de police).  La position III correspond<B>à</B> la circulation de  nuit hors des agglomérations, la source de  courant<B>1</B> alimentant, en plus des feux de po  sition 4, soit les phares<B>5,</B> soit les feux de croi  sement<B>6</B> (code).  



  Un commutateur de commande<B>à</B> pied<B>7,</B>  du type rotatif, est inséré dans le circuit pour  permettre la sélection soit des phares<B>5,</B> soit  des feux de croisement<B>6.</B>  



  Comme on le voit aux     fig.    2 et<B>3,</B> ce com  mutateur comprend un corps<B>8</B> formant boîtier,  présentant des oreilles<B>9,</B> permettant sa fixation  sur le véhicule. Ce corps<B>8</B> est solidaire d'un  prolongement cylindrique<B>10</B> dans lequel est  susceptible de coulisser     axialement,    contre l'ac  tion d'un ressort<B>11,</B> une tige 12 portant<B>à</B> une  de ses extrémités un bouton de commande<B>13.</B>  L'autre extrémité de la tige 12 est reliée<B>à</B> une  pièce 14 en forme de palette présentant une  fente<B>15.</B> Un axe<B>16</B> est fixé transversalement  dans la partie centrale du     boitier   <B>8</B> et la pièce  14 est engagée par sa fente<B>15</B> autour dudit axe  <B>16.</B> Une pièce rotative<B>17,

  </B> en forme d'étoile<B>à</B>  six branches, est disposée sur l'axe<B>16.</B> Un dis  que<B>18</B> en matière isolante est monté lui aussi  de façon rotative sur l'axe<B>16.</B> Ce disque<B>18</B>  porte une plaquette<B>19</B> en forme d'étoile<B>à</B>    trois branches, constituée en métal bon con  ducteur d'électricité. Ce disque<B>18</B> présente une  encoche 20 dans laquelle est engagée une par  tie recourbée 21 d'une branche 22 de la pièce  <B>17.</B>  



  En outre, un ressort, non représenté sur le  dessin, est disposé entre les pièces<B>17</B> et<B>18</B> et  tend<B>à</B> les tenir écartées l'une de l'autre, en  maintenant, toutefois, la partie 21 engagée dans  l'encoche 20<B>;</B> d'autre part, une saillie<B>23</B> est  prévue sur la pièce 14 pour venir buter contre  la branche correspondante de la pièce<B>17</B> lors  de     l'actionnement    du bouton de commande<B>13.</B>  En effet, lors d'un déplacement du bouton<B>13</B>  d'une longueur de course normale, la saillie<B>23</B>  fait tourner les pièces<B>17</B> et<B>18</B> d'un sixième  de tour, et lors du relâchement du bouton<B>13,

  </B>  le ressort<B>11</B> ramène la pièce 14<B>à</B> sa position  initiale sans entraîner les pièces<B>17</B> et<B>18.</B>     L'en-          traffiement    par saccades des pièces<B>17</B> et<B>18</B>  s'effectue de la même manière qu'un entraîne  ment par dispositif<B>à</B> cliquet.  



  Ce commutateur présente, d'autre part, un  couvercle non représenté au dessin et destiné  <B>à</B> venir fermer le boîtier<B>8</B> et<B>à</B> maintenir en  place les diverses pièces rotatives qu'il renferme.  



  Sur ce couvercle, qui peut être entièrement  en matière isolante, sont fixées six bornes 24,  dont les positions sont indiquées en pointillé  <B>à</B> la     fig.   <B>1.</B> Ces bornes 24 sont utilisées pour  diverses connexions du commutateur, con  nexions qui sont susceptibles d'être alimentées  en courant chaque fois que la pièce<B>19</B> est en  contact avec les bornes 24 respectives.  



  Le commutateur représenté aux     fig.    2 et<B>3</B>  comprend encore un contact supplémentaire  du type<B>à</B> rappel élastique en position ouverte.  Ce contact est constitué par une lame élastique  <B>25,</B> qui est isolée par rapport au corps<B>8</B> et des  tinée<B>à</B> être reliée     élastiquement    aux deux bor  nes<B>30</B> et<B>31</B> sous l'action d'un doigt isolé<B>26</B>  qui est solidaire de la plaque 14. La lame<B>25</B>  est reliée     élastiquement   <B>à</B> une borne<B>32</B> qui  est elle-même reliée<B>à</B> l'alimentation des feux  de position 4. La borne<B>30</B> est reliée<B>à</B> une  borne de l'avertisseur acoustique<B>3,</B> dont l'au  tre borne est reliée<B>à</B> une source<B>1</B> de courant      du véhicule.

   La borne<B>31</B> est reliée<B>à</B> l'alimenta  tion des feux de croisement.  



  Lorsque le commutateur 2 se trouve sur la  position I, on voit qu'en appuyant partielle  ment sur le bouton<B>13</B> du commutateur<B>à</B> pied  on ferme d'abord le contact supplémentaire en  reliant les bornes<B>30, 31</B> et<B>32.</B> L'avertisseur  acoustique<B>3</B> fonctionne, car     il    se trouve bran  ché entre la source de courant<B>1</B> et la masse,  par l'intermédiaire des filaments des lampes de  croisement<B>5</B> et des lampes de stationnement 4.  Comme l'ensemble de ces lampes est destiné<B>à</B>  absorber un courant beaucoup plus fort que  celui de l'avertisseur, les chutes de tension  dans ces lampes sont très faibles, de sorte  que l'avertisseur fonctionne dans des conditions  normales et que les filaments des lampes ne  s'échauffent pas sensiblement.

   D'ailleurs, on  rencontre souvent dans les installations connues  un relais destiné<B>à</B> fermer le contact de l'aver  tisseur acoustique, et, dans un tel montage,  c'est l'enroulement d'excitation de ce relais qui  se trouve branché entre la borne<B>30</B> et un pôle  de la batterie<B>1, à</B> la place de l'avertisseur<B>3</B>  représenté. La consommation du relais est, en  général, de<B>1 à</B> 2 watts, tandis que l'ensem  ble de la consommation pour les deux feux de  croisement et l'ensemble des feux de position  s'élève, en général,<B>à</B> une centaine de watts. On  voit que la résistance introduite dans le cir  cuit du relais par les filaments des lampes est  tout<B>à</B> fait négligeable.  



  Lorsque le commutateur 2 est sur la po  sition Il et que l'usager actionne le commuta  teur<B>à</B> pied pour fermer le contact supplémen  taire, on voit que l'avertisseur acoustique ne  peut pas être mis en fonction, car ses deux  bornes sont reliées au même pôle de la batterie.  Par contre, la liaison établie entre la lame<B>25</B>  et la borne<B>31</B> a pour effet d'alimenter les feux  de croisement<B>5</B> pendant la fermeture du con  tact supplémentaire, ce qui permet de faire des  signes optiques. Lorsque le commutateur 2 est  ,sur la position III, l'avertisseur acoustique<B>3</B>  ne peut toujours pas être actionné par le con  tact supplémentaire, puisque ses deux bornes  sont reliées au même pôle de la batterie.

      <B>Il</B> est bien entendu que l'on pourrait pré  voir un autre contact supplémentaire, par exem  <B>ple</B> sous la forme d'un bouton poussoir fixé au  tableau de bord du véhicule, pour permettre  l'utilisation de l'avertisseur acoustique pendant  la circulation nocturne, c'est-à-dire pour les po  sitions II<I>et III</I> du commutateur 2.  



  D'autre part, il est clair que la borne<B>31</B>  pourrait être reliée<B>à</B> l'alimentation des grands  phares<B>6</B> au lieu de l'être<B>à</B> celle des feux de  croisement<B>5.</B> Le contact supplémentaire pour  rait évidemment être disposé différemment sur  le contacteur<B>à</B> pied et au moins certaines des  bornes<B>30 à 32</B> pourraient notamment être  fixées au couvercle (non représenté) du com  mutateur, ce couvercle pouvant être en matière  isolante.



  Lighting and signaling installation, in particular for a motor vehicle The main patent relates to a lighting and signaling installation, in particular for a motor vehicle, comprising a source of electric current intended for <B> to </B> the '' power supply for position lights (parking lights <B> y </B> including rear lights), headlights and dipped beam at least, - a <B> hand </B> switch <B > to </B> three positions corresponding, respectively -, the first <B> to </B> daytime traffic, the current source being capable of supplying certain electrical devices of the vehicle and in particular the acoustic warning device, the second <B> to </B> night circulation in built-up areas, the current source supplying, in addition to the devices supplied in the first position,

   position lights (police lights <B> y </B> including rear lights), the third position corresponding <B> to </B> night traffic outside built-up areas, the current source supplying in addition to lights, either the headlights or the dipped headlights (code), a <B> to </B> switch <B> to </B> foot control being inserted in the circuit to allow the selection of the headlights, or dipped beam headlamps (code), this <B> to </B> foot switch comprising at least one additional contact allowing selection at the foot of a signaling device even when the hand <B> </B> switch is in second position.



  In the embodiment described in the main patent, this additional contact is of the type <B> with </B> elastic return in the open position and actuated at the start of the travel of the operating button of the switch <B> to </B> foot. In this embodiment, it was still possible to activate the horn by pressing <B> to </B> all the way on the <B> to </B> foot switch, which can be a drawback in certain cases, because it is possible that the driver presses the switch too hard to switch from the large headlights to the dipped beam headlights, and that he thus actuates his acoustic warning device inappropriately.



  The present invention aims <B> to </B> remedy <B> to </B> this drawback by virtue of the fact that said additional contact is provided to connect three terminals electrically to each other when it is actuated, these terminals being respectively re linked <B> to </B> the supply of the position lights, <B> to </B> the supply of one of the main beams (codes or headlights) and <B> to </B> a terminal of an acoustic warning device, the other terminal of which is connected <B> to </B> the current source of the vehicle for the three positions of the hand switch <B> to </B>.



  The appended drawing represents, schematically and <B> by </B> by way of example, one embodiment of the object of the invention. Fig. <B> 1 </B> is the electrical diagram <B>; </B> in fig. 2 shows the <B> to </B> foot switch used in this form & execution, its cover being removed <B>; </B> in fig. <B> 3 </B> is a cut <B> through </B> through the switch according to fig. 2.



  The lighting and signaling installation comprises a source of electric current, for example an accumulator battery <B> 1, </B> 'intended <B> to </B> powering position lights ( police), headlights and dipped beam headlights at least. A three-position <B> to </B> main 2 <B> </B> switch is provided for the selection of the various devices <B> to </B> to supply for day and night traffic.

   Position I of switch 2 corresponds to <B> </B> daytime traffic, the current source <B> 1 </B> being capable of supplying certain electrical devices in the vehicle and in particular the alarm. acoustic <B> 3. </B> Position II corresponds <B> to </B> night traffic in built-up areas, the current source <B> 1 </B> supplying power, in addition to powered devices in position I, position lights 4 (police lights). Position III corresponds <B> to </B> night traffic outside built-up areas, the current source <B> 1 </B> supplying, in addition to position lights 4, or headlights <B> 5 , </B> or the dipped headlights <B> 6 </B> (code).



  A <B> foot </B> <B> 7, </B> rotary type control switch is inserted in the circuit to allow selection of either the headlights <B> 5, </B> or the lights crossing <B> 6. </B>



  As seen in Figs. 2 and <B> 3, </B> this switch comprises a body <B> 8 </B> forming a box, having lugs <B> 9, </B> allowing it to be attached to the vehicle. This body <B> 8 </B> is integral with a cylindrical extension <B> 10 </B> in which it is capable of sliding axially, against the action of a spring <B> 11, </ B > a rod 12 carrying <B> at </B> one of its ends a control button <B> 13. </B> The other end of the rod 12 is connected <B> to </B> a part 14 in the form of a pallet with a slot <B> 15. </B> An axis <B> 16 </B> is fixed transversely in the central part of the box <B> 8 </B> and the part 14 is engaged by its slot <B> 15 </B> around said axis <B> 16. </B> A rotating part <B> 17,

  </B> in the shape of a star <B> with </B> six branches, is arranged on the axis <B> 16. </B> A say that <B> 18 </B> in insulating material is also rotatably mounted on the <B> 16 axis. </B> This <B> 18 </B> disc carries a <B> 19 </B> star-shaped plate <B> to < / B> three branches, made of metal, a good conductor of electricity. This disc <B> 18 </B> has a notch 20 in which is engaged a curved part 21 of a branch 22 of the part <B> 17. </B>



  In addition, a spring, not shown in the drawing, is placed between the parts <B> 17 </B> and <B> 18 </B> and tends <B> to </B> keep them apart one by one. on the other, keeping, however, the part 21 engaged in the notch 20 <B>; </B> on the other hand, a projection <B> 23 </B> is provided on the part 14 to come abut against the corresponding branch of part <B> 17 </B> when actuating control button <B> 13. </B> In fact, when moving button <B> 13 </ B> with a normal stroke length, the projection <B> 23 </B> turns parts <B> 17 </B> and <B> 18 </B> a sixth of a turn, and when releasing button <B> 13,

  </B> the spring <B> 11 </B> returns the part 14 <B> to </B> its initial position without dragging the parts <B> 17 </B> and <B> 18. </ B > The jerky loading of parts <B> 17 </B> and <B> 18 </B> is carried out in the same way as a drive using a <B> </B> ratchet device .



  This switch has, on the other hand, a cover not shown in the drawing and intended to <B> </B> come to close the housing <B> 8 </B> and <B> to </B> keep the various rotating parts it contains.



  On this cover, which may be entirely of insulating material, are fixed six terminals 24, the positions of which are indicated in dotted lines <B> to </B> in fig. <B> 1. </B> These 24 terminals are used for various switch connections, which are likely to be supplied with current whenever part <B> 19 </B> is in contact with the terminals 24 respective ones.



  The switch shown in fig. 2 and <B> 3 </B> also comprises an additional contact of the type <B> with </B> elastic return in the open position. This contact is formed by an elastic blade <B> 25, </B> which is isolated from the body <B> 8 </B> and tines <B> to </B> to be elastically connected to the two terminals <B> 30 </B> and <B> 31 </B> under the action of an isolated finger <B> 26 </B> which is integral with the plate 14. The blade <B> 25 </ B> is elastically connected <B> to </B> a terminal <B> 32 </B> which is itself connected <B> to </B> the power supply for the position lights 4. Terminal <B > 30 </B> is connected <B> to </B> a terminal of the acoustic warning device <B> 3, </B> whose other terminal is connected <B> to </B> a source <B> 1 </B> vehicle current.

   Terminal <B> 31 </B> is connected <B> to </B> the dipped beam headlamps supply.



  When switch 2 is in position I, it can be seen that by partially pressing button <B> 13 </B> of the foot switch <B> </B>, the additional contact is first closed by connecting terminals <B> 30, 31 </B> and <B> 32. </B> The acoustic warning device <B> 3 </B> works, because it is connected between the current source <B > 1 </B> and the mass, by means of the filaments of the dipped beam lamps <B> 5 </B> and of the parking lamps 4. As all of these lamps are intended for <B> </ B> absorb a much stronger current than that of the alarm, the voltage drops in these lamps are very small, so that the alarm works under normal conditions and the filaments of the lamps do not heat up noticeably.

   Moreover, one often meets in known installations a relay intended <B> to </B> close the contact of the acoustic warning device, and, in such an assembly, it is the excitation winding of this relay which is connected between terminal <B> 30 </B> and a pole of battery <B> 1, </B> in place of the horn <B> 3 </B> shown. The consumption of the relay is, in general, <B> 1 to </B> 2 watts, while the total consumption for the two dipped beam headlamps and the set of side lights is, in general, <B> to </B> a hundred watts. We see that the resistance introduced into the circuit of the relay by the filaments of the lamps is quite <B> to </B> fact negligible.



  When switch 2 is in position Il and the user actuates the <B> foot </B> switch to close the additional contact, it is seen that the acoustic warning device cannot be activated, because its two terminals are connected to the same pole of the battery. On the other hand, the connection established between the blade <B> 25 </B> and the terminal <B> 31 </B> has the effect of supplying the dipped headlights <B> 5 </B> during the closing of the additional contact, which allows optical signs to be made. When switch 2 is in position III, the acoustic warning device <B> 3 </B> still cannot be actuated by the additional contact, since its two terminals are connected to the same pole of the battery.

      <B> It </B> of course that one could provide another additional contact, for example <B> ple </B> in the form of a push button fixed to the dashboard of the vehicle, to allow the use of the acoustic warning device during night traffic, that is to say for positions II <I> and III </I> of switch 2.



  On the other hand, it is clear that terminal <B> 31 </B> could be connected <B> to </B> the power supply of large headlights <B> 6 </B> instead of being <B> to </B> that of the dipped beam headlights <B> 5. </B> The additional contact could obviously be arranged differently on the <B> foot switch </B> and at least some of the terminals < B> 30 to 32 </B> could in particular be fixed to the cover (not shown) of the switch, this cover possibly being of insulating material.
