Description

La présente invention, due à la collaboration de Monsieur Pascal HA-PHAM, se rapporte à un dispositif de commardes par levier pour régler le chauffage et la climatisation des véhicules automobiles et en particulier à un mécanisme à commandes multiples actionnées au tableau de bord à partir d'un levier unique.The present invention, due to the collaboration of Mr. Pascal HA-PHAM, relates to a lever control device for regulating the heating and air conditioning of motor vehicles and in particular to a multiple control mechanism actuated on the dashboard from of a single lever.

On connait des dispositifs de commandes à distance par levier unique pouvant actionner successivement plusieurs organes de chauffage par l'intermédiaire de cables.Remote control devices are known by single lever which can actuate successively several heating members by means of cables.

Il s'agit en général de commandes mécaniques réalisées à partir du levier principal dont le mouvement est transformé par une série de rainures en forme de camés dans lesquelles sent guidées des tétons. Cames et tétons sont portés alternativement par le levier principal, par des biellettes intermédiaires articulées ou directement par la platine support du mécanisme.These are generally mechanical controls made from the main lever, the movement of which is transformed by a series of cam-shaped grooves in which the nipples feel guided. Cams and pins are carried alternately by the main lever, by articulated intermediate links or directly by the support plate of the mechanism.

Plus précisément, un dispositif connu se compose d'une platine support munie de deux pions fixes autour desquels un levier unique percé de deux lumières curvilignes en regard, vient s'articuler successivement sur chaque pion tandis que l'autre pion coulisse dans sa lumière respective.More specifically, a known device consists of a support plate provided with two fixed pins around which a single lever pierced by two curved lights facing each other, is articulated successively on each pin while the other pin slides in its respective light .

Ce dispositif, plus particulièrement adapté à la commande symétrique de deux câbles accrochés sur le levier, ne permet pas d'obtenir un couple de manoeuvre constant en cas de déséquilibre des efforts demandés par chacun des cables ou encore lorsqu'il est nécessaire de commander plus de deux cables..This device, more particularly suitable for the symmetrical control of two cables hung on the lever, does not make it possible to obtain a constant operating torque in the event of an imbalance of the forces required by each of the cables or even when it is necessary to order more two cables ..

D'autre part, la géométrie de l'ensemble platine-levier et la configuration des lumières ou des cames déterminent de façon rigoureuse la trajectoire de chaque point du levier et donc l'orientatin du départ des cables, qu'il est pratiquement impossible de modifier pour adaptation à différents types de véhicules.On the other hand, the geometry of the lever-lever assembly and the configuration of the lights or the cams rigorously determine the trajectory of each point of the lever and therefore the orientation of the departure of the cables, which it is practically impossible to modify to adapt to different types of vehicles.

Un autre inconvénient réside dans le fait que les lumières de guidage crééent des frottements qui entraînent un durcissement des manoeuvres et des risques de coincement surtout dans le cas d'une fabrication en série économique à fortes tolérances.Another drawback lies in the fact that the guide lights create friction which leads to a hardening of the maneuvers and the risks of jamming, especially in the case of economic mass production with high tolerances.

Le but de l'invention est d'éviter les inconvénients sus-mentionnés et de réaliser un dispositif dé commande par levier unique, pivotant sucessivement autour de deux axes d'articulation et permettant :

  • - d'obtenir une orientation du départ des câbles dans toutes les directions, c'est-à-dire la possibilité de débattements variables en amplitude et en orientation, des divers points d'accrochage.
  • - de pouvoir commander successivement, au moins deux organes de climatisation demandant des efforts de traction inégaux, tout en conservant une régularité des efforts de manoeuvre sur toute la longueur de la course du levier.
  • - d'éliminer les pertes de rendement mécanique dues aux frottements ainsi que tout risque de coincement lors d'une fabrication en série.
The object of the invention is to avoid the above-mentioned drawbacks and to produce a single lever control device, successively pivoting around two articulation axes and allowing:
  • - Obtain an orientation of the departure of the cables in all directions, that is to say the possibility of variable deflections in amplitude and orientation, of the various attachment points.
  • - to be able to control successively, at least two air conditioning units requiring unequal traction forces, while maintaining regularity of the operating forces over the entire length of the lever stroke.
  • - Eliminate losses in mechanical efficiency due to friction as well as any risk of jamming during mass production.

A cet effet, le dispositif objet de l'invention est caractérisé essentiellement par une platine fixe et un levier de manoeuvre articulé sur cette platine par l'intermédiaire d'au moins une'biellette. La biellette est articulée sur la platine par un axe fixe tandis que le levier est articulé sur la biellette par un axe mobile par rapport à la platiné et décalé de l'axe fixe.To this end, the device which is the subject of the invention is essentially characterized by a fixed plate and an operating lever articulated on this plate by means of at least one link. The link is articulated on the plate by a fixed axis while the lever is articulated on the link by an axis movable relative to the plate and offset from the fixed axis.

De la sorte, après que l'ensemble levier-biellette ait pivoté autour de l'axe fixe, la biellette vient en appui contre une butée de la platine si bien que l'axe mobile devient fixe à son tour et que le levier continue sa course en pivotant autour dé cet axe.In this way, after the lever-link assembly has pivoted about the fixed axis, the link comes to bear against a stop of the plate so that the movable axis becomes fixed in turn and the lever continues its stroke by pivoting around this axis.

La forme de la biellette peut être quelconque et posséder divers . prolongements servant à l'accrochage des cables dans une direction prédéterminée.The shape of the link can be any and have various. extensions used for hanging cables in a predetermined direction.

L'emploi d'articulations élimine du même coup les pertes par frottement et les risques de coincement.The use of joints at the same time eliminates friction losses and the risk of jamming.

Selon l'invention, le levier est de préférence articulé au moyen de deux axes mobiles entre deux biellettes respectivement supérieure et inférieure, de telle manière que l'axe d'articulation mobile du levier avec une biellette se superpose rigoureusement avec l'axe d'articulation fixe de l'autre biellette avec la platine, lorsque lesdites biellettes sont en butée simultanément sur la platine.According to the invention, the lever is preferably articulated by means of two movable axes between two upper and lower links respectively, so that the movable articulation axis of the lever with a link strictly overlaps the axis of fixed articulation of the other link with the plate, when said links are in abutment simultaneously on the plate.

Chaque biellette peut être de forme quelconnque et posséder un ou plusieurs prolongements de part et d'autre de l'entr axes pour l'accrochage d'un ou plusieurs câbles.Each link can be of any shape and have a or several extensions on either side of the centreline for hanging one or more cables.

A partir de la position en butée simultanée des biellettes, dite position de repos, le levier peut pivoter sélectivement autour de son premier axe mobile rendu fixe par la biellette en butée en entraînant l'autre biellette articulée sur son deuxième axe mobile.From the position in simultaneous abutment of the rods, called the rest position, the lever can pivot selectively around its first movable axis made fixed by the rod in abutment by driving the other articulated rod on its second movable axis.

La forme du levier de manoeuvre est telle que sa position de repos ne corresponde pas forcément au milieu de sa course en façade, mais soit au contraire décentrée et adaptée aux efforts demandés par chaque commande, pour conserver une certaine régularité des efforts sur toute la longueur de la course.The shape of the operating lever is such that its rest position does not necessarily correspond to the middle of its travel on the front, but is on the contrary off-center and adapted to the forces required by each command, to maintain a certain regularity of the forces over the entire length of the race.

C'est ainsi que le débattement en façade sera plus important lorsqu'une biellette portera deux cables simultanément, ou encore un seul cable dont la manoeuvre sera plus dure que pour celui porté par l'autre biellette.This is how the clearance on the front will be greater when a link will carry two cables simultaneously, or even a single cable whose operation will be harder than that carried by the other link.

D'autres avantages et particularités de l'invention ressortiront de la description qui suit d'un mode de réalisation donné à titre d'exemple en référence au dessin annexé sur lequel :

  • - la figure 1 représente en perspective, le dispositif de commande par levier selon l'invention, dans sa position de repos;
  • - la figure 2 est une vue en coupe dans un plan II passant par les axes d'articulation de la figure 1;
  • - les figures 3 et 4 montrent les deux positions extrêmes du levier pour lesquelles il pivote successivement autour de ses deux axes d'articulation, et
  • - la figure 5 représente une variante de réalisation dans laquelle la forme des biellettes permet une autre orientation du départ des câbles.
Other advantages and particularities of the invention will emerge from the following description of an embodiment given by way of example with reference to the appended drawing in which:
  • - Figure 1 shows in perspective, the lever control device according to the invention, in its rest position;
  • - Figure 2 is a sectional view in a plane II passing through the hinge axes of Figure 1;
  • FIGS. 3 and 4 show the two extreme positions of the lever for which it successively pivots around its two axes of articulation, and
  • - Figure 5 shows an alternative embodiment in which the shape of the rods allows another orientation of the departure of the cables.

En se référant aux figures 1 et 2, le dispositif de commandes selon l'invention se compose essentiellement d'un levier principal ou de manoeuvre 1, monté pivotant sur une platine support 2 par l'intermédiaire d'au moins une biellette 3 de renvoi du mouvement sur laquelle sont accrochés un ou plusieurs.câbles 4 destinés à la commande à distance des organes de climatisation du véhicule.With reference to FIGS. 1 and 2, the control device according to the invention essentially consists of a main or operating lever 1, pivotally mounted on a support plate 2 by means of at least one return link rod 3 of the movement on which are hung one or more cables 4 intended for the remote control of the vehicle air conditioning units.

De préférence, le levier de manoeuvre 1 est articulé par une branche 5 entre deux biellettes parallèles respectivement supérieure 6 et inférieure 3 au moyen de deux axes 7, 8 mobiles.par rapport à la platine, décalés et-montés en sens opposés, tandis que lesdites biellettes sont articulées sur la platine 2 au moyen de deux axes fixes 9, 10, la biellette supérieure 6 étant montée sur un pontet 11 solidaire de la platine 2.Preferably, the operating lever 1 is articulated by a branch 5 between two parallel rods respectively upper 6 and lower 3 by means of two axes 7, 8 movable relative to the plate, offset and-mounted in opposite directions, while said links are articulated on plate 2 by means of two axes fixed 9, 10, the upper link 6 being mounted on a bridge 11 secured to the plate 2.

Comme on-le voit plus clairement sur la figure 2, les entr'axes D des biellettes et du levier sont égaux et les axes d'articulation 8, 9 et 7, 10 se superposent sur les pivots X, Y lorsque le levier et les biellettes occupent la position de la figure 1, dite de repos.As can be seen more clearly in FIG. 2, the centers of axes D of the links and of the lever are equal and the articulation axes 8, 9 and 7, 10 overlap on the pivots X, Y when the lever and the rods occupy the position of Figure 1, called rest.

Dans cette position, chaque biellette 3, 6 est en appui contre une butée 12, 13 de hauteur appropriée, solidaire du bord de la platine 2, opposé à la façade 14. L'autre branche 15 du levier 1, sensiblement à l'équerre avec la première 5, fait saillie par rapport à la façade 14 de la platine et se termine par un bouton de manoeuvre 16 qui est accessible sur le tableau de bord (non représenté) du véhicule.In this position, each link 3, 6 is in abutment against a stop 12, 13 of appropriate height, secured to the edge of the plate 2, opposite to the facade 14. The other branch 15 of the lever 1, substantially square with the first 5, projects from the front 14 of the plate and ends with an operating button 16 which is accessible on the dashboard (not shown) of the vehicle.

Dans la position de repos de la figure 1, le bouton 16 est décentré par rapport au milieu M de la façade, laissant une course inégalé du levier de part et d'autre de cette position, pour une raison qui apparaitra par la suite.In the rest position of FIG. 1, the button 16 is off-center with respect to the middle M of the front panel, leaving an unequaled travel of the lever on either side of this position, for a reason which will appear later.

En dehors du positionnement précis des différents axes d'articulation, les formes du levier 1 et des parties terminales des biellettes 3, 6 servant respectivement à la manoeuvre et à l'accrochage des câbles, peuvent être quelconqueApart from the precise positioning of the different axes of articulation, the shapes of the lever 1 and of the end parts of the links 3, 6 serving respectively for the operation and for the hanging of the cables, can be any

Sur la réalisation représentée, la biellette inférieure 3 présente une partie terminale coudée 17 portant un plot 18 d'accrochage et la biellette supérieure 6 un léger décrochement 19 suivi d'une surface 20 plus évasée portant simultanément deux plots 21, 22 d'accrochage pour deux câbles 23, 24 distincts.In the embodiment shown, the lower link 3 has a bent end portion 17 carrying a lug 18 for attachment and the upper link 6 a slight recess 19 followed by a more flared surface 20 simultaneously carrying two lugs 21, 22 for attachment two separate cables 23, 24.

L'ensemble du dispositif est un assemblage de pièces fabriquées de préférence en plastique moulé. Les axes d'articulation peuvent soit être rapportés et clipsés dans des alésages appropriés, soit venir de moulage avec une pièce et être ensuite clipsés-sur l'autre pièce de l'articulation. C'est ainsi que, sur la figure 2, le levier de manoeuvre 1 intercalé entre les deux biellettes 3,.6 comporte deux axes 7, 8 venant de moulage, clipsés dans les alésages correspondants de .chaque biellette. Ces dernières comportent par ailleurs chacune un axe 9, 10 venant de moulage, clipsé dans l'alésage correspondant de la platine 2, 11. Pour une question de facilité de montage, il est cependant préférable de rapporter l'axe d'articulation 9 du levier supérieur 6.sur le pontet 11.The entire device is an assembly of parts preferably made of molded plastic. The articulation axes can either be attached and clipped into suitable bores, or come from molding with one part and then be clipped onto the other part of the articulation. Thus, in Figure 2, the operating lever 1 interposed between the two rods 3, .6 comprises two axes 7, 8 from molding, clipped into the corresponding bores of .each rod. The latter also each comprise an axis 9, 10 coming from molding, clipped into the corresponding bore of the plate 2, 11. For a question of ease of assembly, it is however preferable to bring back the articulation axis 9 of the upper lever 6.on the trigger guard 11.

Le fonctionnement du dispositif est le suivant, en référence aux figures 3 et 4.The operation of the device is as follows, with reference to FIGS. 3 and 4.

Pour passer de la position de repos (figure 1) à celle de la figuré 3, on déplace le bouton de manoeuvre 16 du levier 1 parallélement à la façade 14 de. la platine, vers l'extrémité correspondant à la course la plus petibe.To move from the rest position (Figure 1) to that of FIG. 3, the operating button 16 of the lever 1 is moved parallel to the front panel 14 of. the plate, towards the end corresponding to the most small stroke.

Le levier, guidé le long de la façade de la platine, entraine la biellette inférieure 3 qui lui est solidaire par l'axe mobile 8, en la faisant pivoter autour de son axe fixe 10 (non visible).The lever, guided along the front of the plate, drives the lower link 3 which is integral with it by the movable axis 8, by pivoting it around its fixed axis 10 (not visible).

Etant données la forme du levier 1 et son articulation simultanée avec la biellette supérieure 6 en appui contre sa butée 13, l'autre axe mobile 7 du levier est rendu provisoirement fixe et se confond avec l'axe fixe 10 de la biellette inférieure.Given the shape of the lever 1 and its simultaneous articulation with the upper link 6 pressing against its stop 13, the other movable axis 7 of the lever is made temporarily fixed and merges with the fixed axis 10 of the lower link.

De ce fait, la biellette inférieure 3 et le levier 1 restent parallèles et pivotent autour du pivot commun Y.Therefore, the lower link 3 and the lever 1 remain parallel and pivot around the common pivot Y.

Lorsque le bouton 16 effectue un aller-retour suivant la flèche Fl, l'extrémité de la biellette inférieure 3'parcourt le débattement . angulaire représenté par la double flèche F2, déterminant ainsi l'orientation et la course du câble de commande (représenté par le plot 18).When the button 16 performs a round trip along the arrow F1, the end of the lower link 3 'traverses the travel. angular represented by the double arrow F2, thus determining the orientation and the stroke of the control cable (represented by the stud 18).

En passant de la figure 3 à la figure 4 via la position de repos (figure 1), la biellette inférieure 3 prend appui contre sa butée 12. De ce fait, l'axe d'articulation 8 avec le levier, initialement mobile, devient fixe, tandis que l'axe d'articulation 7 avec la biellette supérieure 6 devient mobile.Passing from FIG. 3 to FIG. 4 via the rest position (FIG. 1), the lower link 3 bears against its stop 12. As a result, the hinge pin 8 with the lever, initially mobile, becomes fixed, while the hinge pin 7 with the upper link 6 becomes mobile.

Ainsi, au cours de son déplacement total, le levier 1 change de pivot Y vers X par l'immobilisation successive de chacun de ses deux axes mobiles 7, 8.Thus, during its total displacement, the lever 1 changes pivot Y to X by the successive immobilization of each of its two movable axes 7, 8.

La biellette supérieure 6 est alors entrainée par le levier 1 dont la branche 5 lui reste parallèle (entre les deux axes) et pivote à son tour autour de son axe fixe 9 monté sur le pontet 11 de la platine et confondu avec le nouveau pivot.The upper link 6 is then driven by the lever 1, the branch 5 of which remains parallel to it (between the two axes) and in turn pivots around its fixed axis 9 mounted on the bridge 11 of the plate and merged with the new pivot.

Comme précédemment décrit, lorsque le bouton 16 effectue un aller-retour suivant la flèche F3, l'axe mobile 7 du levier se débat suivant F4, ce qui entraine l'extrémité 20 de la biellette supérieure 6 suivant le débattement angulaire représenté par la double flèche F5 en déterminant l'orientation et la course des deux câbles de commande représentés par les plots 21 et 22.As previously described, when the button 16 goes back and forth along the arrow F3, the movable axis 7 of the lever struggles along F4, which causes the end 20 of the upper link 6 according to the angular movement represented by the double arrow F5 by determining the orientation and the stroke of the two control cables represented by the pads 21 and 22.

Le débattement de chaque biellette est lié à sa géométrie et à celle du levier de manoeuvre. Dans la réalisation représentée, la plus grande course du levier 1, à partir de sa position de repos correspond à l'entraînement de la biellette 6 munie de deux plots d'accrochage, c'est-à-dire de celle où l'effort à fournir est le plus important.The travel of each link is linked to its geometry and to that of the operating lever. In the embodiment shown, the greatest stroke of the lever 1, from its rest position corresponds to the drive of the rod 6 provided with two studs attachment, that is to say the one where the effort to provide is the greatest.

Cette démultiplication du mécanisme tend donc à obtenir en cas de déséquilibre des efforts de traction air chacune des biellettes, une régularité des efforts et une douceur de manoeuvre sur toute la course du levier.This reduction in the mechanism therefore tends to obtain, in the event of an imbalance in the air traction forces, each of the links, a regularity of the forces and a smooth maneuvering over the entire stroke of the lever.

Quel que soit le nombre de biellettes utilisées, le mécanisme ne fait intervenir que des pièces et des axes d'articulation simples, ce qui a pour avantages d'éliminer quasi-totalement les pertes mécaniques par frottement et, de plus, de simplifier la fabrication du dispositif en vue d'obtenir des séries économiques.Whatever the number of rods used, the mechanism only involves simple parts and articulation axes, which has the advantages of almost completely eliminating mechanical losses by friction and, moreover, of simplifying the manufacture of the device in order to obtain economic series.

La figure 5 illustre une variante de réalisation dans laquelle les parties terminales d'accrochage des biellettes supérieure 6 et inférieure 3 possèdent d'autres formes. C'est ainsi que la biellette inférieure 3 est prolongée en 26 sur son autre extrémité par rapport à la biellette correspondante des figures 1 à 4 tandis que la biellette supérieure 6 possède un renvoi à l'équerre 25 et un seul plot 27 d'accrochage de câble. Les branches parallèlés et superposées du levier et des biellettes, correspondant aux entr'axes, doivent être conservées pour un fonctionnement identique.FIG. 5 illustrates an alternative embodiment in which the end attachment portions of the upper 6 and lower 3 links have other shapes. Thus, the lower link 3 is extended at 26 at its other end relative to the corresponding link in FIGS. 1 to 4 while the upper link 6 has a reference to the square 25 and a single stud 27 for attachment. of cable. The parallel and superimposed branches of the lever and the rods, corresponding to the centers, must be kept for identical operation.

Comme on le voit, la manoeuvre du bouton 16 suivant les flèches F6 ou F7 .a pour effets d'actionner respectivement les biellettes inférieure en F8 et supérieure en F9 et de donner aux plots 28, 27 des débattements angulaires différents de leurs homologues des figures 3 et 4, ce qui autorise des départs de câbles dans d'autres directions prédéterminées, modifiables à volonté par l'adaptation de l'extrémité des biellettes 3, 6.As can be seen, the operation of the button 16 according to the arrows F6 or F7 . has the effect of actuating respectively the lower links in F8 and upper in F9 and to give the studs 28, 27 different angular deflections from their counterparts in FIGS. 3 and 4, which authorizes cable feeds in other predetermined directions , modifiable at will by adapting the end of the links 3, 6.

Par rapport à la position de repos du levier 1, la plus grande course en façade F7 est encore réservée au débattement du levier supérieur 6, ce qui, dans le cas d'un seul câble de commande, permet d'actionner un organe de climatisation demandant un effort plus important que 1-'autre.Relative to the rest position of the lever 1, the greatest travel on the front F7 is still reserved for the travel of the upper lever 6, which, in the case of a single control cable, makes it possible to actuate an air conditioning unit requiring a greater effort than the other.

Par la modification de la forme du levier principal 1 ramenant le bouton 16 au milieu de la façade 14 en position de repos, on obtient naturellement une répartition équilibrée des efforts sur chaque biellette.By modifying the shape of the main lever 1 bringing the button 16 back to the middle of the front panel 14 in the rest position, a balanced distribution of the forces is naturally obtained on each link.
