Description

  

  Rhéostat    La présente invention a pour objet un  rhéostat, comprenant une série de plots de con  tact avec lesquels coopère un frotteur.  



  Ce rhéostat est caractérisé par le fait que  lesdits plots sont disposés côte<B>à</B>     cÔte,    décalés  les uns par rapport aux autres dans la direction  de déplacement du frotteur, la dimension de  celui-ci, mesurée perpendiculairement<B>à</B> sa di  rection de déplacement, correspondant<B>à</B> l'es  pace occupé par l'ensemble des plots mesuré  également perpendiculairement<B>à</B> cette direction.  



  Le dessin annexé représente,<B>à</B> titre d'exem  <B>ple,</B> une forme d'exécution de l'objet de l'in  vention.  



  La     fig.   <B>1</B> est une vue en plan schématique du  rhéostat.  



  La     fig.    2 est une coupe axiale du rhéostat  muni d'une commande<B>à</B> pédale, et,  la     fig.   <B>3</B> est une vue en plan du rhéostat.  Le rhéostat représenté pourra servir<B>à</B> des  fins quelconques, notamment au démarrage  d'un moteur électrique tel par exemple<B>le</B> mo  teur d'une machine<B>à</B> -coudre.  



  <B>Il</B> comprend quatre résistances numérotées  <B>de 1 à</B> 4 montées en série et quatre plots de  contact<B>5 à 8</B> reliés chacun respectivement<B>à</B>  l'entrée d'une des résistances<B>1 à</B> 4. Le rhéostat    comprend en outre un cinquième plot, désigné  par<B>9,</B> relié directement<B>à</B> la borne<B>de</B> sorti--<B>10.</B>  La borne     d!-entrée   <B>11</B> est reliée<B>à</B> un frotteur 12  se déplaçant en un mouvement de translation  dans la direction de la flèche<B>13.</B>  



  Les cinq plots de contact<B>5 à 9</B> sont     déca-          16s    les uns par rapport aux autres dans la direc  tion<B>13</B> du déplacement du frotteur 12. La lar  geur de ce dernier, mesurée perpendiculaire  ment<B>à</B> la direction<B>13,</B> est légèrement<B>supé-</B>  rieure<B>à</B>     l'espace,occupé    par les cinq plots, éga  lement mesuré perpendiculairement<B>à</B> la direc  tion<B>13.</B>  



  Lorsque le frotteur s'approche des plots, il  entre d'abord en contact avec<B>le</B> plot<B>5,</B> mettant  en circuit les quatre résistances<B>1 à</B> 4<B>;</B> poursui  vant son avance,<B>il</B> entre en contact avec<B>le</B>  plot<B>6,</B> mettant hors circuit la résistance<B>1,</B> puis  avec les plots<B>7, 8</B> et<B>9,</B> mettant successivement  hors circuit les résistances 2,<B>3</B> et 4.  



  Grâce<B>à</B> cette -disposition générale, la course  totale du frotteur peut être maintenue très fai  ble, étant indépendante de l'espace     quIl,    con  vient de ménager entre les plots et ne dépen  dant, outre du nombre des plots, que de la dis  tance de décalage entre chacun feux. Cette  distance peut être réduite bien au-dessous de  l'espace minimum qui doit être ménagé entrer  les plots pour des raisons de sécurité de fonc  tionnement.

        Dans la forme d'exécution représentée dans  les     fi#g.    2 et<B>3, le</B> frotteur est un rouleau et les  plots font partie     dun    circuit imprimé.     Toute,-          fois    ces désignations communément admises  dans<B>le</B> domaine des appareils     6lectriqueÀs    ont       été    conservées ici.    Les plots<B>5 à 9</B> font partie d'un circuit im  primé sur une plaquette de base rigide 14. L'en  semble     desenroulements   <B>1 à</B> 4 sont montés sur  une bobine commune<B>15</B> située derrière la     pila-          quette    14.

   Cette dernière constitue une surface  de roulement pour le frotteur 12 formé d'un  cylindre rotatif ou rouleau porté par un étrier  <B>16</B> élastique, relié<B>à</B> la borne d'entrée<B>11</B> du  rhéostat. L'extrémité     decet    étrier est encastrée  dans un support<B>17</B> fixé<B>à</B> une pédale<B>18</B>     ar-          tioulée    elle-même en<B>19</B> sur un bâti, 20.

       Les     mouvements oscillants de la pédale<B>18</B> autour  de l'axe<B>19</B> produisent les déplacements<B>du cy-</B>  lindre 12 suivant la flèche<B>13.</B> Grâce<B>à</B>     Pélas-          ticité    de l'étrier<B>16,</B> le cylindre est maintenu ap  puyé contre la plaquette 14 et entre successi  vement en contact avec     >es    plots<B>5 à 9.</B>  



       Uinvention    n'est pas limitée<B>à</B> la forme  d'exécution décrite et représentée<B>:</B> le nombre  des plots pourrait être différent<B>;</B> on pourrait  prévoir le cas de plots<B>de</B> petite surface tels  que     lecontact    soit interrompu sur un plot      & ors#     que le frotteur passe sur le plot suivant.  



  Les résistances, au lieu de former un bobi  nage indépendant, pourraient être imprimées  directement sur la Plaquette 14.



  Rheostat The present invention relates to a rheostat, comprising a series of contact pads with which a wiper cooperates.



  This rheostat is characterized by the fact that said pads are arranged side <B> to </B> side, offset with respect to each other in the direction of movement of the wiper, the dimension of the latter, measured perpendicularly <B> to </B> its direction of displacement, corresponding <B> to </B> the space occupied by all the plots, also measured perpendicularly <B> to </B> this direction.



  The appended drawing represents, <B> by </B> by way of <B> ple, </B> an embodiment of the object of the invention.



  Fig. <B> 1 </B> is a schematic plan view of the rheostat.



  Fig. 2 is an axial section of the rheostat equipped with a pedal <B> </B> control, and, FIG. <B> 3 </B> is a plan view of the rheostat. The rheostat shown can be used <B> for </B> any purpose, in particular for starting an electric motor such as for example <B> the </B> motor of a <B> to </B> machine. -to sew.



  <B> It </B> comprises four resistors numbered <B> from 1 to </B> 4 mounted in series and four contact pads <B> 5 to 8 </B> each connected respectively <B> to </ B> the input of one of resistors <B> 1 to </B> 4. The rheostat also includes a fifth pad, designated by <B> 9, </B> directly connected <B> to </ B > terminal <B> of </B> output-- <B> 10. </B> Terminal of! -input <B> 11 </B> is connected <B> to </B> a wiper 12 moving in a translational motion in the direction of the arrow <B> 13. </B>



  The five contact pads <B> 5 to 9 </B> are offset with respect to each other in the direction <B> 13 </B> of the movement of the wiper 12. The width of the latter, measured perpendicularly <B> to </B> the direction <B> 13, </B> is slightly <B> greater- </B> greater <B> than </B> the space, occupied by the five plots, also measured perpendicularly <B> to </B> the direction <B> 13. </B>



  When the wiper approaches the pads, it first comes into contact with <B> the </B> pad <B> 5, </B> switching on the four resistors <B> 1 to </B> 4 <B>; </B> continuing its advance, <B> it </B> comes into contact with <B> the </B> pad <B> 6, </B> switching off the resistor < B> 1, </B> then with pads <B> 7, 8 </B> and <B> 9, </B> successively switching off resistors 2, <B> 3 </B> and 4 .



  Thanks <B> to </B> this general -disposition, the total stroke of the wiper can be kept very low, being independent of the space which it should be left between the studs and not depending, in addition to the number of plots, that of the offset distance between each light. This distance can be reduced well below the minimum space which must be left between the studs for operational safety reasons.

        In the embodiment shown in fi # g. 2 and <B> 3, the </B> wiper is a roller and the pads are part of a printed circuit. However, these designations, commonly accepted in <B> the </B> field of electrical appliances, have been retained here. The pads <B> 5 to 9 </B> are part of a circuit printed on a rigid base board 14. All of the windings <B> 1 to </B> 4 are mounted on a common coil < B> 15 </B> located behind pilquette 14.

   The latter constitutes a running surface for the wiper 12 formed of a rotating cylinder or roller carried by an elastic caliper <B> 16 </B>, connected <B> to </B> the input terminal <B> 11 </B> of the rheostat. The end of this bracket is embedded in a support <B> 17 </B> fixed <B> to </B> a pedal <B> 18 </B> itself articulated in <B> 19 </ B> on a frame, 20.

       The oscillating movements of the pedal <B> 18 </B> around the axis <B> 19 </B> produce the movements <B> of the cylinder </B> 12 according to the arrow <B> 13. </B> Thanks <B> to </B> the elasticity of the caliper <B> 16, </B> the cylinder is kept pressed against the plate 14 and successively comes into contact with> the pads < B> 5 to 9. </B>



       The invention is not limited <B> to </B> the embodiment described and shown <B>: </B> the number of pads could be different <B>; </B> one could foresee the case small surface <B> </B> pads such that the contact is interrupted on a pad & ors # that the wiper passes on the next pad.



  The resistors, instead of forming an independent bobbin, could be printed directly on Plate 14.
