Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne un dispositif d'ajustement de l'élévation d'une pièce d'extrémité. La pièce peut constituer une butée, par exemple pour un ouvrant d'un véhicule automobile tel qu'un capot, une porte de coffre, un hayon. En ajustant l'élévation de la pièce, on peut avec précision positionner l'ouvrant en position refermée avec le reste de la carrosserie.The present invention relates to a device for adjusting the elevation of an end piece. The piece may constitute an abutment, for example for an opening of a motor vehicle such as a hood, a trunk door, a tailgate. By adjusting the elevation of the workpiece, it is possible to accurately position the opening in the closed position with the rest of the bodywork.

ARRIERE PLAN TECHNOLOGIQUE DE L'INVENTIONBACKGROUND OF THE INVENTION

On connaît du document FR3002574 un tel dispositif. Il comprend une douille destinée à être solidarisée au véhicule et un organe de réglage, portant une butée, pouvant coulisser dans la douille de manière à placer la butée à une hauteur déterminée. Le dispositif est alors verrouillé en imposant un mouvement à l'organe de réglage visant à placer des ergots de retenue dans des rainures de blocage et à faire coopérer des dents et des gorges aménagées respectivement sur les organes de réglage et sur la douille pour bloquer tout mouvement de l'organe de réglage et figer la hauteur de la butée.Document is known FR3002574 such a device. It comprises a bushing intended to be secured to the vehicle and an adjusting member bearing a stop, slidable in the bushing so as to place the stop at a given height. The device is then locked by imposing a movement on the adjusting member to place retaining lugs in locking grooves and to cooperate teeth and grooves respectively provided on the adjusting members and on the sleeve to block all movement of the adjusting member and freeze the height of the stop.

La solution proposée par ce document permet effectivement de placer la butée à une hauteur déterminée. Elle ne permet pas toutefois d'ajuster cette hauteur simplement, notamment après que le dispositif ait été placé en position de verrouillage.The solution proposed by this document makes it possible to place the stop at a given height. However, it does not allow to adjust this height simply, especially after the device has been placed in the locking position.

On connait du document DE29716111 un dispositif permettant de placer une butée à une hauteur déterminée. Dans ce document la hauteur est indexée par le biais d'éléments flexibles portant des ergots, disposés sur la douille, qui viennent s'indenter dans des rainures de l'organe de réglage.We know of the document DE29716111 a device for placing a stop at a given height. In this document the height is indexed by means of flexible elements bearing lugs, arranged on the sleeve, which are indent in grooves of the adjusting member.

La solution proposée par ce document est particulièrement fragile et présente un risque de casse des éléments flexibles lors du vissage de l'organe de réglage dans la douille. De plus, ce dispositif nécessite de disposer d'un espace suffisant dans son environnement, permettant aux éléments flexibles de se déformer.The solution proposed by this document is particularly fragile and presents a risk of breakage of the flexible elements when screwing the adjusting member in the socket. In addition, this device requires to have sufficient space in its environment, allowing the flexible elements to deform.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

  • the figure 2 represents another view of a device according to the invention;
  • the figure 3 represents a section at one end of the pin of a device according to the invention.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En référence aux figures 1 et 2, un dispositif d'ajustement 1 de l'élévation d'une pièce d'extrémité conforme à l'invention comprend un corps 2 destiné à être rendu solidaire d'un support. Par « élévation » on désigne, dans la présente demande, la distance séparant la pièce d'extrémité d'un point de référence du corps 2. Dans le cas où le dispositif 1 constitue une butée d'un ouvrant d'un véhicule automobile, le support peut être constitué d'un élément de carrosserie ou du châssis du véhicule.With reference to figures 1 and 2 , an adjustment device 1 of the elevation of an end piece according to the invention comprises a body 2 intended to be secured to a support. By "elevation" is meant, in the present application, the distance separating the end piece from a reference point of the body 2. In the case where the device 1 constitutes a stop of an opening leaf of a motor vehicle, the support may consist of a body element or the chassis of the vehicle.

Quelle que soit la nature du support, celui-ci est muni d'une ouverture dans lequel le corps 2 du dispositif d'ajustement 1 peut être introduit pour y être retenu. À cet effet, le corps 2 peut être muni d'organes de retenue, tels que des pattes flexibles permettant d'emboîter élastiquement le corps 2 au support, ou de moyens de verrouillage 3 permettant de maintenir fermement le corps 2 au support.Whatever the nature of the support, it is provided with an opening in which the body 2 of the adjustment device 1 can be introduced to be retained. In this Indeed, the body 2 may be provided with retaining members, such as flexible tabs for elastically fitting the body 2 to the support, or locking means 3 for firmly holding the body 2 to the support.

Avantageusement, le corps 2 peut être muni d'une collerette d'appui permettant de le faire reposer sur le support. La collerette peut éventuellement être munie d'une rondelle d'étanchéité, par exemple en élastomère, permettant de refermer de manière étanche l'ouverture dans lequel le corps 2 a été introduit.Advantageously, the body 2 may be provided with a support flange allowing it to rest on the support. The flange may optionally be provided with a sealing washer, for example elastomer, to seal the opening in which the body 2 has been introduced.

Le corps 2 s'étend selon une direction longitudinale et défini un cylindre central à base circulaire muni d'un filetage interne. Le cylindre présente d'un côté et de l'autre du corps 2 une première ouverture 4a et une seconde ouverture 4b.The body 2 extends in a longitudinal direction and defines a central cylinder with a circular base provided with an internal thread. The cylinder has on one side and the other of the body 2 a first opening 4a and a second opening 4b.

Un dispositif d'ajustement 1 conforme à la présente description comporte également une goupille 5, également de forme cylindrique, portant un filetage externe. Cette goupille 5 présente une première extrémité 5a configurée pour recevoir, par exemple par emboîtement ou tout autre moyen de fixation, la pièce d'extrémité 6 dont on souhaite ajuster d'élévation. Dans l'exemple représenté sur les figures, cette pièce d'extrémité 6 est constituée d'une butée formée d'un matériau élastomère.An adjustment device 1 according to the present description also comprises a pin 5, also of cylindrical shape, carrying an external thread. This pin 5 has a first end 5a configured to receive, for example by interlocking or any other fastening means, the end piece 6 which is desired to adjust elevation. In the example shown in the figures, this end piece 6 consists of a stop formed of an elastomeric material.

Les dimensions de la goupille 5 et du cylindre central du corps 2 sont choisies pour que les deux pièces puissent être assemblées entre elles par l'intermédiaire de leurs filetages respectifs, par vissage. La goupille 5, lorsque qu'elle est entraînée en rotation, peut alors se déplacer selon une direction longitudinale, ce qui permet d'ajuster l'élévation de la pièce d'extrémité, ici la butée élastomère 6.The dimensions of the pin 5 and the central cylinder of the body 2 are chosen so that the two parts can be assembled together through their respective threads, by screwing. The pin 5, when it is rotated, can then move in a longitudinal direction, which allows to adjust the elevation of the end piece, here the elastomeric abutment 6.

Comme cela est bien connu en soi, le pas des filetages interne du cylindre central et externe de la goupille est choisi pour déterminer la variation d'élévation de la pièce d'extrémité 6 pour chaque rotation complète de la goupille 5 dans le corps 2. À titre d'exemple, en choisissant un pas de 4 mm, on fera varier l'élévation de la pièce d'extrémité 6 de + ou - 2 mm d'une élévation nominale, en imposant une rotation d'un demi-tour de la goupille 5 dans un sens ou dans l'autre.As is well known per se, the pitch of the internal threads of the central and outer cylinder of the pin is chosen to determine the variation of elevation of the end piece 6 for each complete rotation of the pin 5 in the body 2. By way of example, by choosing a pitch of 4 mm, the elevation of the end piece 6 by +/- 2 mm will be varied by a nominal elevation, by imposing a rotation of a half-turn of the pin 5 in one direction or the other.

Poursuivant la description des figures 1 et 2, la seconde extrémité 5b de la goupille 5 est pourvue d'au moins deux fentes 11 longitudinales et débouchantes. Ces deux fentes 11 définissent deux pattes flexibles 7 sur la seconde extrémité 5b de la goupille 5. Comme cela sera rendu apparent dans la suite de cette description, on pourra prévoir plus de deux fentes 11 est donc plus de deux pattes flexibles 7.Continuing the description of figures 1 and 2 , the second end 5b of the pin 5 is provided with at least two slots 11 longitudinal and open. These two slots 11 define two flexible tabs 7 on the second end 5b of the pin 5. As will become apparent later in this description, it can provide more than two slots 11 is more than two flexible tabs 7.

Les pattes flexibles 7, dans l'exemple avantageux représenté sur les figures, présentent chacune un épaulement 8. Lorsque l'on introduit la seconde extrémité 5b de la goupille 5 dans l'ouverture 4a du corps 2 pour la visser dans le cylindre central, les pattes flexibles 7 se rétractent pour permettre le déplacement longitudinal de la goupille 5 selon une direction d'enfoncement. Une fois que la goupille 5 a suffisamment progressé dans le corps 2 pour faire déboucher les pattes flexibles 7 du côté de la seconde ouverture de ce corps 2, les pattes flexibles 7 reprennent leur position et placent les épaulements 8 en butée avec le bord périphérique du corps 2. Ce mécanisme prévient le dévissage de la goupille 5 et permet de fixer l'élévation maximale de la pièce d'extrémité 6 vis-à-vis du corps 2. Cela permet également de faciliter le montage en permettant de faire un pré-enfonçage et un pré-maintien de la goupille 5 au corps 2 avant d'effectuer le vissage de la goupille 5.The flexible tabs 7, in the advantageous example shown in the figures, each have a shoulder 8. When the second end 5b of the pin 5 is inserted into the opening 4a of the body 2 to screw it into the central cylinder, the flexible tabs 7 retract to allow the longitudinal displacement of the pin 5 in a direction of depression. Once the pin 5 has advanced sufficiently in the body 2 to open the flexible tabs 7 on the side of the second opening of the body 2, the flexible tabs 7 resume their position and place the shoulders 8 abutting with the peripheral edge of the 2. This mechanism prevents unscrewing of the pin 5 and makes it possible to fix the maximum elevation of the end piece 6 vis-à-vis the body 2. This also facilitates assembly by allowing a pre-sinking and a pre-holding of the pin 5 to the body 2 before performing the screwing of the pin 5.

Comme cela est apparent sur la figure 1 et sur la section du corps 2 représentée sur la figure 3, le corps 2 présente également au moins un bossage 9 sur sa surface interne, c'est-à-dire celle orientée vers la goupille 5. Sur l'exemple représenté sur ces figures, le corps 2 présente deux bossages 9 se faisant face, respectivement formés sur les bras longitudinaux 10a, 10b d'une anse 10.As is apparent on the figure 1 and on the section of the body 2 shown on the figure 3 , the body 2 also has at least one boss 9 on its inner surface, that is to say the one facing the pin 5. In the example shown in these figures, the body 2 has two bosses 9 facing each other, respectively formed on the longitudinal arms 10a, 10b of a loop 10.

Les bossages 9 forment une restriction du diamètre du cylindre interne du corps 2 si bien qu'elles sont susceptibles de déformer les pattes flexibles 7 de la goupille 5 lorsque celle-ci est disposée selon une position angulaire dans le corps 2 mettant les pattes flexibles 8 en vis-à-vis des bossages 9. Les bossages 9 sont également configurés pour venir se loger dans certaines des fentes 11 lorsque la goupille 5 est disposée selon une position angulaire dans le corps 2 mettant certaines fentes 11 en vis-à-vis des bossages 9. Dans cette configuration, les pattes flexibles 7 reprennent leurs dispositions naturelles. A cet effet, les bossages 9 présentent une dimension similaire ou inférieure à la largeur des fentes 11.The bosses 9 form a restriction of the diameter of the inner cylinder of the body 2 so that they are capable of deforming the flexible tabs 7 of the pin 5 when it is disposed in an angular position in the body 2 putting the flexible tabs 8 9. The bosses 9 are also configured to be housed in some of the slots 11 when the pin 5 is disposed in an angular position in the body 2 putting certain slots 11 opposite the bosses 9. In this configuration, the flexible legs 7 resume their natural arrangements. For this purpose, the bosses 9 have a dimension similar to or smaller than the width of the slots 11.

D'une manière générale, les bossages 9 sont disposés angulairement autour du cylindre central du corps 2 pour venir s'engager tous simultanément dans les fentes 11 aménagées sur la goupille 5. Dans l'exemple représenté, les deux bossages 9 sont disposés sur le corps 2 diamétralement à l'opposé l'un de l'autre et quatre fentes 11 de la goupille 5 sont séparées angulairement de 90° l'une de l'autre.In general, the bosses 9 are angularly arranged around the central cylinder of the body 2 to engage all simultaneously in the slots 11 arranged on the pin 5. In the example shown, the two bosses 9 are arranged on the body 2 diametrically opposite one another and four slots 11 of the pin 5 are angularly separated by 90 ° from each other.

Le haut de l'anse 10 relie chaque bras longitudinal 10a, 10b et les maintiens fermement en position lorsque les pattes flexibles 7 sont en appui forcé sur les bossages 9.The top of the handle 10 connects each longitudinal arm 10a, 10b and holds them firmly in position when the flexible tabs 7 are forced against the bosses 9.

Lorsque l'on visse la goupille 5 dans le corps 2 selon la direction d'enfoncement pour ajuster l'élévation de la pièce d'extrémité 6, on déplace les fentes 11 en rotation en faisant se rétracter les pattes flexibles 7. On engage les bossages 9 dans certaines de ces fentes 11 pour indexer la rotation de la goupille 5 et assurer un positionnement fixe, en position de blocage, de l'élévation de la pièce d'extrémité.When the pin 5 is screwed into the body 2 according to the driving direction in order to adjust the elevation of the end piece 6, the slots 11 are displaced in rotation by retracting the flexible tabs 7. bosses 9 in some of these slots 11 to index the rotation of the pin 5 and ensure a fixed position in the locking position, the elevation of the end piece.

Dans l'exemple représenté, chaque quart de tour de la goupille forme un cran de positionnement de la pièce d'extrémité. Selon le pas choisi des filetages interne et externe, chaque quart de tour, c'est-à-dire entre deux positions de blocage, ajuste l'élévation de la pièce d'extrémité 6 d'une grandeur déterminée.In the example shown, each quarter turn of the pin forms a positioning notch of the end piece. According to the chosen pitch of the internal and external threads, each quarter turn, that is to say between two locking positions, adjusts the elevation of the end piece 6 by a determined quantity.
