Description
La présente invention concerne un dispositif pour la manoeuvre télécommandée d'éléments généraux coulissants de la carrosserie des véhicules automobiles, tels que toits ouvrants escamotables, portières et similaires, ce dispositif étant utilisable de façon particulièrement avantageuse pour la manoeuvre des glaces coulissantes et des portes latérales, à savoir, en bref, en tant que "lève-glaces". The present invention relates to a device for the remote controlled operation of general sliding elements of the bodywork of motor vehicles, such as retractable sunroofs, doors and the like, this device being particularly advantageous for the operation of sliding windows and side doors. , namely, in short, as "window regulators".
On sait que les dispositifs lève-glaces actuels, qu'ils soient à commande motorisée ou manuelle, se servent de systèmes à cable de structure très compliquée et de fiabilité réduite qui présentent, entre autres, l'inconvénient de subir avec le temps et l'usure, des jeux considérables qui compromettent la fermeture parfaite de la glace. We know that current window regulators, whether motorized or manual, use cable systems of very complicated structure and reduced reliability which have, among other things, the disadvantage of being subject to over time and l wear, considerable play which compromises the perfect closing of the window.
Le but de l'invention est essentiellement d'éliminer lesdits inconvénients précités én réalisant un dispositif de manoeuvre des glaces, en particulier, et des éléments coulissants tels que spécifiés ci-dessus, en général, de structure particulièrement simple, de fonctionnement fiable et propre à requérir l'installa- tion d'une puissance très réduite dans la version de construction dans laquelle ladite manoeuvre est motorisée. Cela signifie que, dans la version à manoeuvre manuelle, la commande se fait avec une grande souplesse en permettant l'emploi d'organes de commande réalisés en matériaux légers et, bleuir tour, structuralement simplifiés. The object of the invention is essentially to eliminate the above-mentioned drawbacks by providing a device for operating the windows, in particular, and the sliding elements as specified above, in general, of particularly simple structure, of reliable and clean operation. to require the installation of a very reduced power in the construction version in which said operation is motorized. This means that, in the manual operation version, the control is done with great flexibility by allowing the use of control members made of light materials and, turn blue, structurally simplified.
Un autre objectif important de l'invention consiste à réaliser un dispositif pratiquedent exempt de jeux d'usure, en mesure de garantir également dans le temps, une fermeture parfaite des éléments coulissants manoeuvrés aoec exclusion de formation d'interstices et, en conséquence, d'infiltrations d'air et d'eau. Another important objective of the invention is to provide a practical device free from wear and tear, able to also guarantee over time, perfect closure of the sliding elements operated with the exclusion of formation of gaps and, consequently, d 'air and water infiltration.
Les objectifs précités ainsi que d'autres qui apparaîtront clairement dans la description détaillée qui suit,sont atteints selon l'invention, par un dispo- sitif pour la manoeuvre de glaces et d'autres éléments généraux coulissants, tels que spécifiés ci-dessus,dont la caractéristique essentielle réside dans le fait qu'il comprend une crémaillère fixe orientée pa rallèlement à la trajectoire de coulissement de la glace ou de l'élément général, et un pignon, calé à l'extrémité d'un arbre moteur supporté à rotation par une base fixée à ladite glace ou l'élément général, de façon que la rotation de l'arbre moteur et du pignon calé sur celui-ci, entrain, en vertu de l'engagement d'engrOnement entre pignon et crémaillère, le déplacement correspondant de la glace ou similaire. The aforementioned objectives as well as others which will appear clearly in the detailed description which follows, are achieved according to the invention, by a device for the operation of windows and other general sliding elements, as specified above, whose essential characteristic resides in the fact that it comprises a fixed rack oriented pa parallel to the sliding path of the glass or of the general element, and a pinion, wedged at the end of a motor shaft supported for rotation by a base fixed to said glass or the general element, so that the rotation of the motor shaft and of the pinion wedged thereon causes, by virtue of the engagement of meshing between pinion and rack, the displacement matching ice cream or the like.
Dans la forme de réalisation à manoeuvre motorisée, le pignon est calé à l'extrémité de l'arbre d'un moteur électrique du type à sens de rotation réversible et la base est constituée par le carter du stator dudit moteur qui est relié à la glace ou similaire, de préférence par l'interposition de matériau élastiquement flexible. Le pignon et la glace sont situés de cotés opposés par rapport à la- crémaillère, laquelle est constituée par un profilé robuste en ,sur la nervure, correspondant à la jambe du T, de laquelle vient s'emboiter à coulissement une fourche solidaire du carter dudit moteur, pour servir de guide à la glace ou de l'élément coulissant et-de retenue de l'engrènement entre le pignon et la crémaillère. In the embodiment with motorized operation, the pinion is wedged at the end of the shaft of an electric motor of the reversible direction of rotation type and the base is formed by the casing of the stator of said motor which is connected to the ice or the like, preferably by the interposition of elastically flexible material. The pinion and the glass are situated on opposite sides with respect to the rack, which is constituted by a robust profile in, on the rib, corresponding to the leg of the T, from which a fork integral with the casing slides. of said motor, to serve as a guide for the ice or of the sliding element and of retaining the meshing between the pinion and the rack.
Dans la forme de réalisation à manoeuvre manuelle, 1arbre moteur est relié torsionnellement à l'extrémité d'un câble de transmission flexible du type
Bowden, tandis que l'autre extrémité du câble est reliée saune manivelle d'actionnement.In the manually operated embodiment, the motor shaft is torsionally connected to the end of a flexible transmission cable of the type
Bowden, while the other end of the cable is connected to its actuating crank.
L'invention sera mieux comprise à la lecture de la description détaillée qui va suivre, d'une forme de réalisation donnée à titre d'exemple indicatif, mais nullement limitatif, en référence aux dessins annexés, dans lesquels:
- la figure 1 représente une vue d'ensemble du dispositif de l'invention, dans la version motorisée, appliquée à la manoeuvre de la glace dè la porte latérale d'un véhicule automobile, ladite glace étant du type à rabattement par coulissement vertical;
- la fgure 2 représente une vue en coupe partielle, à échelle agrandie, selon la ligne II-II de la figure 1;
- la figure 3 représente une vue en coupe selon la ligne III-III de la figure 2; et
- la figure 4 représente une vue en coupe montrant le détail d'un élément de fixation du carter du moteur à la glace.The invention will be better understood on reading the detailed description which follows, of an embodiment given by way of indicative example, but in no way limiting, with reference to the appended drawings, in which:
- Figure 1 shows an overview of the device of the invention, in the motorized version, applied to the operation of the window of the side door of a motor vehicle, said window being of the type with folding down by vertical sliding;
- Figure 2 represents a view in partial section, on an enlarged scale, along line II-II of FIG. 1;
- Figure 3 shows a sectional view along line III-III of Figure 2; and
- Figure 4 shows a sectional view showing the detail of an element for fixing the motor housing to the window.
En se référant auxdites figures, on indique génériquement par 10, la portière du véhicule automobile, et, par 11, la glace coulissant verticalement jusqu'à disparition dans la baie intérieure 12 de la portière, la glace étant retenue à coulissement par au moins un canal de guidage latéral 13. Dans la baie 12, sensiblement en correspondance de la ligne médiane de la glace1 est disposée et solidement fixée à la structure de la portière, une crémaillère 14. La denture de la crémail ibère, avantageusement tournée vers l'intérieur de la baie 12,-est aménagée sur l'aile-d'un profilé métallique en T dont l'axe longitudinal est orienté-parallèlement à la direction de coulissement de la glace 11. Referring to said figures, the door of the motor vehicle is generically indicated by 10, and, by 11, the glass sliding vertically until disappearance in the interior bay 12 of the door, the glass being held to slide by at least one lateral guide channel 13. In the bay 12, substantially in correspondence with the center line of the glass1 is disposed and firmly fixed to the structure of the door, a rack 14. The teeth of the Iberian rack, advantageously turned inward bay 12, -is fitted on the wing-of a metal T-shaped section whose longitudinal axis is oriented-parallel to the sliding direction of the glass 11.
Si la glace Il est cintrée,le guide 13 ainsi que la crémaillère 14 sont alors cintrés de façon correspondante. Avec la denture de la crémaillère, engrène un pignon 15 calé à l'extrémité de l'arbre d'un moteur électrique du type à sens de rotation réversible, globalement indiqué par 16. If the glass II is bent, the guide 13 as well as the rack 14 are then bent correspondingly. With the teeth of the rack, a pinion 15 is wedged at the end of the shaft of an electric motor of the type with reversible direction of rotation, generally indicated by 16.
Le carter du stator du moteur 16 est fixé, par l'interposition d'un étrier métallique 17, au bord inférieur de las glace, ledit étrier étant doté d'un cadre 18 dans lequel s'engage ledit bord de la glace. The stator casing of the motor 16 is fixed, by the interposition of a metal stirrup 17, to the lower edge of the glass, said stirrup being provided with a frame 18 in which said edge of the glass engages.
En outre, l'étrier est rigidement fixé à la glace à l'aide de boulons 19 qui s'engagent, en les dilatant, dans des tampons en matériaux élastiques 20.In addition, the stirrup is rigidly fixed to the glass by means of bolts 19 which engage, by expanding them, in buffers made of elastic materials 20.
A l'étrier 17, du côté du pignon 15, est également fixée une console 21 dans laquelle vient s'engager à coulissement, la nervure du profilé formant la crémaillère 14 afin de former un guide ultérieur pour la glace et une retenue pour l'engrènement du pignon 15 sur la crémaillère 14 la glace Il et le pignon 15 étant situés de cotés opposés par rapport à la crémail- 1père. To the stirrup 17, on the side of the pinion 15, is also fixed a console 21 in which is slidably engaged, the rib of the profile forming the rack 14 in order to form a subsequent guide for the ice and a retainer for the meshing of the pinion 15 on the rack 14 the glass II and the pinion 15 being located on opposite sides with respect to the rack 1père.
Lorsque le moteur 16 est actionné, l'engrènement du pignon sur la crémaillère produit, grace au fait que le carter du stator dudit moteur est solidaire de la glace, le coulissement de cette dernière en remontée et, respectivement en descente suivant le sens de rotation dudit moteur, la commande de ce dernier s'effectuant au moyen de boutons-poussoirs, d'une façon connue en soi. When the motor 16 is activated, the meshing of the pinion on the rack produces, thanks to the fact that the stator casing of said motor is integral with the glass, the sliding of the latter in ascent and, respectively in descent according to the direction of rotation of said motor, the control of the latter being effected by means of push-buttons, in a manner known per se.
Dans la forme de réalisation à manoeuvre manuelle, le pignon 15 est calé à l'extrémité d'un arbre moteur supporté par une base fixée à glace 11 par un étrier 17 tel que décrit ci-dessus. L'arbre moteur est torsionnellement relié à une extrémité d'un câble flexible du type Bowden, l'autre extrémité dudit câble étant reliée torsionnellement, directement ou par l'interposition d'un multiplicateur, à une manivelle d'actionnement. In the manually operated embodiment, the pinion 15 is wedged at the end of a drive shaft supported by a base fixed to glass 11 by a stirrup 17 as described above. The motor shaft is torsionally connected to one end of a flexible cable of the Bowden type, the other end of said cable being connected torsionally, directly or by the interposition of a multiplier, to an actuating crank.
il est évident, d'après la description faite cidessus, que le dispositif de l'invention peut être ap pliqué, outre à la manoeuvre d'une glace Il comme décrit ci-dessus, à la production du coulissement d'ouverture et de fermeture de quelconques éléments coulissants de carrosserie, tels que toits escamotables, portes latérales de fourgons et similaires, dans quel cas, la crémaillère 14 se trouve alors disposée latéralement, de façon à ne pas interférer avec la baie de l'ouverture fermée dudit élément coulissant. it is obvious, from the description given above, that the device of the invention can be applied, in addition to the operation of a window II as described above, to the production of the opening and closing sliding any sliding bodywork elements, such as retractable roofs, side doors of vans and the like, in which case, the rack 14 is then disposed laterally, so as not to interfere with the opening of the closed opening of said sliding element.
En outre il va de soi qu'en respectant le principe de l'invention, on peut faire légèrement varier les détails d'exécution et les formes de réalisation par rapport à ceux décrits et illustrés à titre d'exemple non limitatif ci-dessus, sans pour autant s'écarter du cadre et de l'esprit de ladite invention. In addition, it goes without saying that by respecting the principle of the invention, the execution details and the embodiments can be slightly varied compared to those described and illustrated by way of nonlimiting example above, without departing from the scope and spirit of said invention.
