MECANISME D'EXTRACTION D'UNE POIGNEE AFFLEURANTE POUR EXTRACTION MECHANISM OF A FLUSHING HANDLE FOR

PORTE DE VEHICULE.VEHICLE DOOR.

La presente invention concerne un mecanisme servant a extraire d'une cavite dans laquelle elle est logee, une poignee de porte de vehicule qui affleure avec la surface exterieure de la porte. De facon generale, elle s'applique egalement a ['extraction d'un levier affleurant The present invention relates to a mechanism for extracting from a cavity in which it is housed, a vehicle door handle which is flush with the outside surface of the door. In general, it also applies to the extraction of a flush lever

loge dans une cavite.lodges in a cavity.

Dans les vehicules modernes, on cherche a realiser des poignees de portes qui ne fassent pas saillie par rapport a la paroi exterieure de la o porte, afin d'eliminer les risques d'accrochage et d'ameliorer l'aerodynamisme du vehicule. La solution qui a ete le plus couramment adoptee jusqu'a present pour resoudre ce probleme consiste a loger la poignee a l'interieur d'une cavite formee par emboutissage sur la paroi exterieure de la porte, et a disposer la poignee de maniere qutelle vienne In modern vehicles, it is sought to produce door handles which do not protrude relative to the outer wall of the door, in order to eliminate the risks of snagging and to improve the aerodynamics of the vehicle. The solution that has been most commonly adopted so far to solve this problem is to house the handle inside a cavity formed by stamping on the outer wall of the door, and to arrange the handle as it comes

a l'affleurement de ladite paroi.at the outcrop of said wall.

Pour pouvoir saisir la poignee avec la main, il est necessaire que la cavite soit plus large que la poignee, mais on cree ainsi dans la cavite, de part et d'autre de la poignee, un espace vice non obture dans lequel peuvent s'accumuler des poussieres et peuvent egalement se former des o tourbillons et des turbulences qui peuvent avoir un effet nefaste sur To be able to grasp the handle with the hand, it is necessary that the cavity is wider than the handle, but we thus create in the cavity, on both sides of the handle, a vice space not closed in which can s' accumulate dust and can also form o vortices and turbulence which can have a harmful effect on

l'aerodynamisme du vehicule.the aerodynamics of the vehicle.

La presente invention vise a remedier a cet inconvenient de la technique anterieure et, a cet effet, elle a pour objet un mecanisme d' extraction d' une poignee d' ouverture pour porte de vehicule, qui est logee a l' interieur d' une cavite formee sur la face exterieure de la porte et occupant une partie de la surface de la cavite, ledit mecanisme etant caracterise en ce qu'il comporte au moins une palette qui occupe la surface restante de la cavite, la poignee et la palette etant montees pivotantes autour d'un axe commun, a partir d'une position de repos dans laquelle elles recouvrent a elles deux entierement l'ouverture de la cavite et vent toutes deux a l'affleurement de la paroi exterieure de la porte, la palette etant susceptible d'etre enfoncee senle vers l'interieur de la cavite a partir de sa position de repos, rendant ainsi accessible a la main un bord de la poignee, qui peut alors etre tiree pour ouvrir la porte. Du fait que dans la position de repos, la poignee d'ouverture et la palette remplissent exactement toute la surface de l'ouverture de la The present invention aims to remedy this drawback of the prior art and, for this purpose, it relates to a mechanism for extracting an opening handle for a vehicle door, which is housed inside a cavity. formed on the outer face of the door and occupying part of the surface of the cavity, said mechanism being characterized in that it comprises at least one pallet which occupies the remaining surface of the cavity, the handle and the pallet being pivotally mounted around a common axis, from a rest position in which they cover the two of them entirely the opening of the cavity and both wind on the surface of the outer wall of the door, the pallet being capable of '' to be pushed only towards the interior of the cavity from its rest position, thus making accessible by hand an edge of the handle, which can then be pulled to open the door. Because in the rest position, the opening handle and the paddle exactly fill the entire surface of the opening of the

2 28403412 2840341

cavite et forment avec la porte une surface continue, il ne se produit pas de tourbillon de l'air ni d'accumulation de poussiere dans la cavite. De cavity and form with the door a continuous surface, there is no air vortex or accumulation of dust in the cavity. Of

plus, la porte presente une bonne finition et un aspect esthetique. more, the door has a good finish and an aesthetic appearance.

Selon une variante de [' invention, le mecanisme d' extraction comporte un inverseur de mouvement monte pivotant dans la cavite, a l'arriere de la poignee et de la palette, et qui est susceptible d'ejecter la According to a variant of the invention, the extraction mechanism comprises a movement reverser mounted to pivot in the cavity, behind the handle and the paddle, and which is capable of ejecting the

poignee hors de la cavite lorsque la palette est enfoncee dans la cavite. handle out of the cavity when the pallet is pushed into the cavity.

L'inverseur de mouvement peut etre realise sous forme d'un arbre cylindrique dispose parallelement a l' axe commun de pivotement de la o poignee d'ouverture et de la palette, ledit arbre etant monte pivotant autour de son axe a l'arriere de la poignee et de la palette et portent a ses extremites deux bras formant poussoirs stetendant dans des directions radiales differentes et dont les extremites vent respectivement en appui sur la face arriere de la palette et de la poignee, un ressort de rappel etant prevu pour ramener l'inverseur dans sa position de repos The motion reverser can be produced in the form of a cylindrical shaft arranged parallel to the common pivot axis of the opening handle and of the pallet, said shaft being mounted to pivot about its axis at the rear of the handle and the pallet and carry at its ends two arms forming pushers extending in different radial directions and the ends of which wind respectively on the rear face of the pallet and the handle, a return spring being provided to bring the reverser in its rest position

pour laquelle la poignee et la palette vent a l'affleurement de la cavite. for which the handle and the paddle wind is flush with the cavity.

Ainsi, lorsque l'utilisateur enforce la palette, celle-ci repousse le poussoir qui se trouve derriere elle, provoquant ainsi le pivotement de l'inverseur de mouvement autour de son axe. Dans ce mouvement de o l' arbre, l' autre pou ssoir fait ressortir la poignee d'ouverture hors de la cavite, avec un mouvement amplifie, de sorte que l'utilisateur peut la Thus, when the user reinforces the pallet, the latter pushes the pusher which is behind it, thereby causing the movement reverser to pivot about its axis. In this movement from where the shaft, the other can bring out the opening handle out of the cavity, with an amplified movement, so that the user can

saisir et ouvrir la porte.enter and open the door.

Avec reference aux figures 1 a 4, la porte de vehicule 10 comporte une cavite 12 formee par emboutissage de la paroi exterieure. Cette cavite est representee avec une forme oblongue, mais elle peut etre rectangulaire, circulaire ou autre. La cavite est de preference orientee horizontalement, mais elle peut aussi etre verticale. Dans cette cavite, vent montees pivotantes une palette 14 et une poignee d'ouverture de porte 16 qui vent realisees sensiblement sous forme de plaques allongees et plates, de formes et dimensions choisies pour qu'elles recouvrent la totalite de la surface de la cavite, au jeux pres. Dans le mode de realisation represente sur la figure 1, la palette et la poignee ont des formes et des dimensions identiques et recouvrent done chacune la moitie de la surface de la cavite, mais elles peuvent avoir des formes et des dimensions differentes, pourvu qu'elles recouvrent ensemble toute la surface de la cavite. Dans la position de repos de la palette et de la poignee qui est representee en traits continus sur la figure 2, leurs faces exterieures vent a l'affleurement de With reference to Figures 1 to 4, the vehicle door 10 has a cavity 12 formed by stamping the outer wall. This cavity is represented with an oblong shape, but it can be rectangular, circular or other. The cavity is preferably oriented horizontally, but it can also be vertical. In this cavity, wind pivotally mounted a pallet 14 and a door opening handle 16 which are produced substantially in the form of elongated and flat plates, of shapes and dimensions chosen so that they cover the entire surface of the cavity, at the pres games. In the embodiment shown in FIG. 1, the pallet and the handle have identical shapes and dimensions and therefore each cover half of the surface of the cavity, but they can have different shapes and dimensions, provided that they cover the entire surface of the cavity together. In the rest position of the pallet and the handle which is shown in solid lines in FIG. 2, their outer faces wind at the outcrop of

la paroi exterieure de la porte.the outside wall of the door.

Comme le montre la figure 3, la palette et la poignee d'ouverture o vent pourvues a une de leurs extremites de charnieres 18, 20 qui recoivent un axe commun 22 fixe dans la cavite, de sorte que la palette et la poignee peuvent pivoter independamment l' une de l' autre. La palette 14 peut pivoter autour de l'axe 22 vers l'interieur de la cavite, a l'encontre de la force d'un premier ressort 24 qui tend a la rappeler a sa position de repos ou elle est a l'affleurement de la paroi de la porte. Par contre, la poignee 16 peut etre tiree a ltexterieur de la cavite a l'encontre de la force d'un second ressort 26 qui tend a la ramener a sa position de As shown in FIG. 3, the pallet and the opening handle are provided at one of their ends with hinges 18, 20 which receive a common axis 22 fixed in the cavity, so that the pallet and the handle can pivot independently one from the other. The pallet 14 can pivot around the axis 22 towards the interior of the cavity, against the force of a first spring 24 which tends to return it to its rest position or it is flush with the door wall. On the other hand, the handle 16 can be pulled outside the cavity against the force of a second spring 26 which tends to bring it back to its position of

repos ou elle est a l'affleurement de la paroi de la porte. rest where it is flush with the wall of the door.

Ainsi, comme le montre la figure 4, lorsque la palette 14 est o enfoncee a la main dans la cavite 12, jusqu'a la position montree en traits tiretes sur la figure 2, le bord de la poignee 16 devient accessible a la main de l'utilisateur. La poignee peut alors etre tiree afin d'ouvrir la porte. La palette et la poignee vent rappelees a leur position de repos Thus, as shown in FIG. 4, when the pallet 14 is pushed into the cavity 12 by hand, up to the position shown in dashed lines in FIG. 2, the edge of the handle 16 becomes accessible by hand. the user. The handle can then be pulled to open the door. The paddle and the wind handle recalled to their rest position

par les ressorts 24, 26 des qutelles ne vent plus sollicitees. by the springs 24, 26 of which they are no longer stressed.

On se referee a present aux figures 5 et 6 qui representent un We now refer to Figures 5 and 6 which represent a

second mode de realisation du mecanisme d' extraction selon [' invention. second embodiment of the extraction mechanism according to the invention.

Ce mode de realisation comportant des elements identiques a ceux du This embodiment comprising elements identical to those of

premier mode de realisation, on ne les decrira pas a nouveau. first embodiment, we will not describe them again.

Ce mecanisme d' extraction comporte en outre un inverseur de mouvement 28 qui est capable de faire ressortir la poignee d'ouverture 16 hors de la cavite lorsque la palette 14 est enfoncee dans la cavite. L'inverseur de mouvement comprend un arbre cylindrique 30 qui est monte pivotant autour d'un axe 32 fixe dans la cavite, a l'arriere de la palette et de la poignee. Aux extremites de l'arbre partent deux bras formant poussoirs 34, 36 qui s'etendent dans deux directions radiales o differentes formant un angle obtus. Les extremites des poussoirs stappuient respectivement sur la face arriere de la palette et de la poignee. L'inverseur est rappele par un ressort de rappel 38 dans une position d'equilibre pour laquelle il place la palette et la poignee dans This extraction mechanism further comprises a movement reverser 28 which is capable of bringing the opening handle 16 out of the cavity when the pallet 14 is pressed into the cavity. The movement reverser comprises a cylindrical shaft 30 which is mounted to pivot about an axis 32 fixed in the cavity, at the rear of the pallet and of the handle. At the ends of the shaft, two arms form pushers 34, 36 which extend in two radial o different directions forming an obtuse angle. The ends of the pushers rest respectively on the rear face of the pallet and the handle. The reverser is returned by a return spring 38 in an equilibrium position for which it places the pallet and the handle in

leur position affleurante.their flush position.

Lorsque lton enforce la palette 14, celle-ci repousse le poussoir 34, ce qui provoque le pivotement de l' inverseur 2 8 a l' encontre de la force du ressort 38. L'autre poussoir 36 fait alors ressortir la poignee d'ouverture 16 hors de la cavite, de sorte que l'utilisateur peut la saisir When lton reinforces the pallet 14, the latter pushes the plunger 34, which causes the pivoting of the inverter 2 8 against the force of the spring 38. The other plunger 36 then brings out the opening handle 16 out of the cavity, so the user can grasp it

pour ouvrir la porte.to open the door.

o On notera que la poignee 16 ressortira hors de la cavite d'autant plus que le poussoir correspondent 36 est pres de l'axe de rotation 22 de ladite poignee, car il se produit un effet d' amplification du mouvement du au bras de levier forme par les deux poussoirs. Ainsi, en placant l'inverseur suffisamment pres de l'axe de rotation 22, on pourra obtenir une bonne sortie de la poignee moyennant un faible o It will be noted that the handle 16 will come out of the cavity all the more since the corresponding pusher 36 is near the axis of rotation 22 of said handle, because there is an effect of amplification of the movement of the lever formed by the two pushers. Thus, by placing the reverser close enough to the axis of rotation 22, it will be possible to obtain a good exit from the handle with a small

enforcement de la palette.enforcement of the palette.

De nombreuses modifications peuvent etre apportees aux modes de realisation qui viennent d'etre decrits. Par exemple, au lieu de se trouver au-dessus de la poignee, comme dans le cas de la figure 1, la Many modifications can be made to the embodiments which have just been described. For example, instead of being above the handle, as in Figure 1, the

o palette peut etre disposee sous la poignee. o pallet can be placed under the handle.

On peut concevoir egalement que deux palettes soient prevues de part et d'autre de la poignee. L'utilisateur pourra alors au choix It is also conceivable that two pallets are provided on either side of the handle. The user can then choose

enforcer l'une ou l'autre des palettes pour saisir la poignee. press one or the other of the pallets to grip the handle.

Enfin, ['invention peut s'appliquer non senlement aux poignees de porte, mais egalement a tout levier qui est loge dans une cavite, chaque fois que lton souhaite obturer cette cavite pour eviter tout effet nefaste, par exemple ['introduction de poussiere ou de corps etrangers. En Finally, the invention can be applied not only to the door handles, but also to any lever which is housed in a cavity, each time that one wishes to close this cavity to avoid any harmful effect, for example ['introduction of dust or foreign bodies.
