Description

La présente invention a essentiellement pour objet un dispositif de retenue de porte en position ouverte pouvant être monté par exemple sur un véhicule automobile.The present invention essentially relates to a door retaining device in the open position which can be mounted for example on a motor vehicle.

Il est déjà connu de prévoir entre le battant et le dormant de porte d'un véhicule automobile des moyens permettant de maintenir positivement le battant en position ouverte selon un angle d'ouverture défini.It is already known to provide means between the leaf and the door frame of a motor vehicle making it possible to positively maintain the leaf in the open position at a defined opening angle.

Toutefois, les moyens connus et proposés jusqu'à maintenant pour parvenir à ce but ne donnaient pas toujours pleine et entière satisfaction sur le plan de la fiabilité et de la résistance à l'usure notamment.However, the means known and proposed hitherto for achieving this goal did not always give full satisfaction in terms of reliability and resistance to wear in particular.

Aussi, la présente invention a pour but de remédier à ces inconvénients en proposant un dispositif de retenue de porte particulier qui présente toutes les qualités voulues de fiabilité et de résistance, et qui permet en outre de conférer à la porte une multiplicité de positions angulaires d'ouverture pour lesquelles la porte demeure fermement maintenue.Also, the present invention aims to remedy these drawbacks by proposing a particular door retaining device which has all the desired qualities of reliability and resistance, and which also makes it possible to give the door a multiplicity of angular positions d opening for which the door remains firmly held.

A cet effet, l'invention a pour objet un dispositif de retenue de porte en position ouverte pouvant être monté par exemple sur un véhicule automobile et du type comprenant un élément denté solidaire du battant de la porte. Ce dispositif est caractérisé par un autre élément denté solidaire du dormant de la porte et susceptible de venir en prise avec l'élément denté du battant, lequel élément denté est flexible pour retenir le battant en position ouverte suivant l'angle d'ouverture choisi.To this end, the subject of the invention is a door retaining device in the open position which can be mounted for example on a motor vehicle and of the type comprising a toothed element integral with the door leaf. This device is characterized by another toothed element integral with the frame of the door and capable of coming into engagement with the toothed element of the leaf, which toothed element is flexible to retain the leaf in the open position according to the chosen opening angle.

Selon un développement avantageux de ce dispositif, les éléments dentés précités forment deux surfaces munies de dents sensiblement parallèles, à savoir une première surface fixée sur le dormant suivant un plan qui est sensiblement vertical et parallèle à l'axe de pivotement du battant, et une deuxième surface fixée sur le battant suivant sensiblement un arc de cercle entourant ledit axe de pivotement constitué par exemple par des charnières à axe vertical.According to an advantageous development of this device, the abovementioned toothed elements form two surfaces provided with substantially parallel teeth, namely a first surface fixed to the frame in a plane which is substantially vertical and parallel to the pivot axis of the leaf, and a second surface fixed to the leaf substantially following an arc of a circle surrounding said pivot axis constituted for example by hinges with a vertical axis.

On précisera encore ici que les éléments ou surfaces dentés précités sont chacune en un matériau élastique, par exemple en résine acétal pour ce qui est de la surface fixée sur le dormant, et en polyamide pour ce qui est de la surface fixée sur battant.It will also be specified here that the abovementioned toothed elements or surfaces are each made of an elastic material, for example of acetal resin as regards the surface fixed to the frame, and of polyamide as regards the surface fixed to the leaf.

Suivant encore un autre développement du dispositif selon l'invention, la position ouverte des deux surfaces dentées fixées respectivement sur le dormant et le battant est telle que le nombre de dents venant en prise et donc le couple de retenue devient plus grand au fur et à mesure que l'angle d'ouverture du battant devient plus important.According to yet another development of the device according to the invention, the open position of the two toothed surfaces fixed respectively to the frame and the leaf is such that the number of teeth engaging and therefore the retaining torque becomes greater as and as the opening angle of the leaf becomes larger.

Les surfaces dentées sont, suivant un exemple de réalisation préféré, fixées et tendues sur respectivement le dormant et le battant au moyen de pions ou analogues clippés dans des orifices ménagés dans ce dormant et ce battant.The toothed surfaces are, according to a preferred embodiment, fixed and tensioned respectively on the frame and the leaf by means of pins or the like clipped into orifices formed in this frame and this leaf.

Suivant encore un autre développement du dispositif selon l'invention, la surface dentée fixée sur le battant est dépourvue de dents à ses extrémités qui comportent deux retours formant entre eux un angle sensiblement égal à 90° après fixation sur ledit battant.According to yet another development of the device according to the invention, the toothed surface fixed on the leaf is devoid of teeth at its ends which have two returns forming between them an angle substantially equal to 90 ° after fixing on said leaf.

Il convient encore de remarquer que, selon la présente invention, au moins la fixation de la surface dentée sur le battant est réglable pour permettre un réglage préalable de sa mise sous tension ou en contrainte.It should also be noted that, according to the present invention, at least the fixing of the toothed surface on the leaf is adjustable to allow prior adjustment of its tensioning or stressing.

On précisera encore ici que l'une des extrémités précitées de la surface dentée fixée sur le battant est munie d'au moins une butée coopérant avec le dormant pour définir un angle d'ouverture maximal du battant.It will also be specified here that one of the abovementioned ends of the toothed surface fixed to the leaf is provided with at least one stop cooperating with the frame to define a maximum opening angle of the leaf.

Mais d'autres particularités et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels :

  • La figure 1 est une vue partielle et en coupe transversale d'un dormant et d'un battant de porte en position de fermeture, ce dormant et ce battant étant équipés du dispositif conforme au principe de l'invention.
  • La figure 2 représente en coupe transversale et à l'état libre l'élément denté monté sur le battant.
  • Les figures 3 et 4 représentent respectivement les éléments dentés fixés sur le dormant et sur le battant en vue de face suivant respectivement les flèches III et IV apparaissant sur les figures 1 et 2.
However, other particularities and advantages of the invention will appear better in the detailed description which follows and which refers to the appended drawings, given solely by way of example, and in which:
  • Figure 1 is a partial view in cross section of a frame and a door leaf in the closed position, this frame and this leaf being equipped with the device according to the principle of the invention.
  • Figure 2 shows in cross section and in the free state the toothed element mounted on the leaf.
  • FIGS. 3 and 4 respectively represent the toothed elements fixed on the frame and on the leaf in front view respectively according to the arrows III and IV appearing in FIGS. 1 and 2.

Suivant un exemple de réalisation, et en se reportant notamment à la figure 1, on voit qu'un dispositif conforme à l'invention comprend essentiellement deux éléments dentés 1 et 2 fixés respectivement sur le dormant D et le battant B d'une porte de véhicule, ces deux éléments étant susceptibles de venir en prise l'un avec l'autre lors de l'ouverture du battant pour le retenir en position ouverte suivant l'angle d'ouverture choisi.According to an exemplary embodiment, and with particular reference to FIG. 1, it can be seen that a device according to the invention essentially comprises two toothed elements 1 and 2 fixed respectively to the frame D and the leaf B of a door of vehicle, these two elements being capable of coming into engagement with one another when the leaf is opened to retain it in the open position according to the chosen opening angle.

Le dormant ou pied de porte D est, suivant l'exemple de réalisation représenté, formé d'un assemblage de deux emboutis 3 et 4 définissant un montant tubulaire présentant une section horizontale sensiblement rectangulaire. L'embouti 3, situé du côté extérieur du véhicule, comporte un renforcement 5 avec fond plat 6 sur lequel est fixé l'élément denté 1 qui se présente sous la forme d'une grille ou surface 7 munie d'une pluralité de dents 8 et réalisée en résine acétal.The frame or door leg D is, according to the embodiment shown, formed by an assembly of two stampings 3 and 4 defining a tubular upright having a substantially rectangular horizontal section. The stamp 3, located on the outside of the vehicle, comprises a reinforcement 5 with flat bottom 6 on which is fixed the toothed element 1 which is in the form of a grid or surface 7 provided with a plurality of teeth 8 and made of acetal resin.

La surface dentée 7 est fixée sur la face ou fond plat 6 du dormant D par quatre pions ou analogues 9 (voir figures 1 et 3), clippés dans des orifices ménagés dans ladite surface plane 5. Ainsi, la surface élastique 7 avec ses dents parallèles 8 est fixée sur le dormant D suivant un plan qui est vertical et qui est parallèle à l'axe de pivotement X du battant B de la porte.The toothed surface 7 is fixed to the flat face or bottom 6 of the frame D by four pins or the like 9 (see FIGS. 1 and 3), clipped into holes made in said flat surface 5. Thus, the elastic surface 7 with its teeth 8 is fixed on the frame D along a plane which is vertical and which is parallel to the pivot axis X of the leaf B of the door.

On a montré en 10 un joint d'étanchéité creux qui adhère au dormant D, et est situé du côté du battant B, ce joint 10 entourant la jonction 11 des deux emboutis 3 et 4 formant le dormant D. Ce joint 10 est destiné à être écrasé en position de fermeture du battant B de la porte, par un repli de feuillure 12 faisant partie de ce battant.A hollow seal was shown at 10 which adheres to the frame D, and is located on the side of the leaf B, this seal 10 surrounding the junction 11 of the two stampings 3 and 4 forming the frame D. This seal 10 is intended to be crushed in the closed position of the leaf B of the door, by a fold of rebate 12 forming part of this leaf.

Comme on le voit clairement sur les figures 1, 2 et 4, l'élément denté 2 fixé sur le battant est constitué par une grille ou surface 13 munie d'une pluralité de dents parallèles 14, et présentant à l'état libre (figure 2) sensiblement la forme d'un arc de cercle d'environ 130°. La surface 13 est de préférence réalisée en polyamide et elle est fixée sur le battant B en entourant l'axe de pivotement X, de sorte que les dents 14 sont ainsi sensiblement parallèles aux dents 8 de la surface dentée 7 et peuvent venir en prise avec ces dents lors du pivotement du battant de porte B.As can be clearly seen in FIGS. 1, 2 and 4, the toothed element 2 fixed on the leaf consists of a grid or surface 13 provided with a plurality of parallel teeth 14, and having in the free state (FIG. 2) substantially the shape of an arc of a circle of approximately 130 °. The surface 13 is preferably made of polyamide and it is fixed to the leaf B by surrounding the pivot axis X, so that the teeth 14 are thus substantially parallel to the teeth 8 of the toothed surface 7 and can come into engagement with these teeth when the door leaf B is pivoted.

Plus précisément, la surface dentée 13 présente deux extrémités 15 et 16 dépourvues de dents et comportant chacune un retour ou repli 15a, 16a. Les replis 15a, 16a portent chacun des pions ou analogues 17 qui peuvent pénétrer dans des perçages de la feuillure du battant de porte B pour ainsi assurer la fixation par clippage de la surface dentée 13. Comme on le voit sur la figure 1, les deux retours ou replis 15a et 16a forment entre eux un angle sensiblement égal à 90° après fixation de la surface dentée 13 sur le battant B, cette fixation assurant bien sûr la mise sous tension de ladite surface, comme on peut le comprendre en considérant les figures 1 et 2.More specifically, the toothed surface 13 has two ends 15 and 16 devoid of teeth and each comprising a return or fold 15a, 16a. The folds 15a, 16a each carry pins or the like 17 which can penetrate holes in the rebate of the door leaf B so as to ensure the fixing by clipping of the toothed surface 13. As can be seen in FIG. 1, the two returns or folds 15a and 16a form between them an angle substantially equal to 90 ° after fixing the toothed surface 13 on the leaf B, this fixing ensuring of course the tensioning of said surface, as can be understood by considering the figures 1 and 2.

A cet égard, on peut prévoir dans le repli de feuillure 12 plusieurs perçages 18 pouvant recevoir les pions 17 et permettant un réglage préalable de la mise sous tension de la surface dentée 13.In this respect, it is possible to provide in the rebate fold 12 several bores 18 capable of receiving the pins 17 and allowing prior adjustment of the tensioning of the toothed surface 13.

Le retour ou repli 15a de la surface 13 comporte un trou 19 dans lequel peut s'engager un moyen approprié 20 de fixation supplémentaire de la surface dentée 13 sur la feuillure du battant de porte. On a montré en 21 une butée faisant saillie de l'extrémité lisse 15 de la surface dentée 13 et destinée à coopérer avec le dormant D pour définir un angle d'ouverture maximal du battant B.The return or fold 15a of the surface 13 has a hole 19 in which a suitable means 20 for additional fixing of the toothed surface 13 can be engaged on the rebate of the door leaf. There has been shown at 21 a stop protruding from the smooth end 15 of the toothed surface 13 and intended to cooperate with the frame D to define a maximum opening angle of the leaf B.

Comme cela apparaît sur la figure 1, une pièce en caoutchouc ou en matériau synthétique 22 est écrasée entre le retour ou repli 15a et la partie arquée de la surface dentée 13 de manière à mettre celle-ci en contrainte.As shown in Figure 1, a piece of rubber or synthetic material 22 is crushed between the return or fold 15a and the arcuate part of the toothed surface 13 so as to put the latter under stress.

Au voisinage de la butée 21 est prévu un trou 23 dans la partie lisse 15 de la surface dentée 13, ce trou permettant le passage d'un outil pour permettre la fixation par clippage du repli 15a de la grille ou surface dentée 13.In the vicinity of the stop 21 is provided a hole 23 in the smooth part 15 of the toothed surface 13, this hole allowing the passage of a tool to allow fixing by clipping the fold 15a of the grid or toothed surface 13.

Comme on l'a dit précédemment, le montage de la surface dentée 13 confère à cette surface une contrainte puisqu'à l'état initial les replis 15a, 16a de ladite surface font entre eux un angle voisin de 140° comme on le voit sur la figure 2, et qu'après montage, lesdits replis font entre eux un angle de 90°, comme on le voit sur la figure 1. Une telle contrainte de la grille ou surface 13 tend à faire pénétrer les dents 14 dans la denture 8 de la grille ou surface 7 solidaire du dormant D. Et pour passer d'un angle d'ouverture du battant B à un autre, il faut déformer la surface dentée, ce qui nécessite un effort aussi bien dans le sens de l'ouverture que dans le sens de la fermeture, ce qui signifie que le battant de porte sera correctement maintenu à l'angle d'ouverture choisi.As mentioned above, the mounting of the toothed surface 13 gives this surface a constraint since in the initial state the folds 15a, 16a of the said surface form an angle close to 140 ° between them as seen on Figure 2, and that after assembly, said folds form an angle of 90 ° between them, as seen in Figure 1. Such stress of the grid or surface 13 tends to penetrate the teeth 14 in the teeth 8 of the grid or surface 7 integral with the frame D. And to change from one opening angle of the leaf B to another, it is necessary to deform the toothed surface, which requires an effort both in the direction of opening and in the closing direction, which means that the door leaf will be correctly maintained at the chosen opening angle.

A cet égard, si l'on se reporte à la figure 1, on voit que si l'on fait tourner le battant de porte B autour de ses charnières ou axe de pivotement X dans le sens inverse des aiguilles d'une montre, on obtient :

  • - pour un angle de 20°, une dent en prise,
  • - pour un angle de 33°, deux dents en prise,
  • - pour un angle de 45°, quatre dents en prise,
  • - pour un angle de 56°, six dents en prise,
  • - pour un angle de 67°, sept dents en prise, et
  • - pour un angle de 78°, sept dents en prise, la surface dentée 13 venant en butée pour cette valeur d'angle.
In this regard, if we refer to Figure 1, we see that if we rotate the door leaf B around its hinges or pivot axis X counterclockwise, we obtains:
  • - for an angle of 20 °, one tooth engaged,
  • - for an angle of 33 °, two teeth engaged,
  • - for an angle of 45 °, four teeth engaged,
  • - for an angle of 56 °, six teeth engaged,
  • - for an angle of 67 °, seven teeth engaged, and
  • - For an angle of 78 °, seven teeth in engagement, the toothed surface 13 abutting for this angle value.

On comprend donc que le nombre de dents 14 et 8 venant en prise, et donc le couple de retenue, devient plus grand au fur et à mesure que l'angle d'ouverture du battant B devient plus important.It is therefore understood that the number of teeth 14 and 8 engaging, and therefore the retaining torque, becomes greater as the opening angle of the leaf B becomes greater.

On a donc réalisé suivant l'invention un dispositif de retenue de porte qui est remarquablement simple et fiable, est peu coûteux, ne nécessite aucun graissage, n'engendre aucun bruit ni grincement, résout les problèmes de corrosion et ne nécessite pas de pièces supplémentaires pour garantir l'étanchéité.A door retaining device has therefore been produced according to the invention which is remarkably simple and reliable, is inexpensive, requires no lubrication, generates no noise or squeaks, solves corrosion problems and does not require additional parts. to guarantee watertightness.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.

Device according to claim 1, characterized in that the aforesaid toothed elements (1, 2) form two substantially parallel surfaces (7,13) provided with teeth (8, 14), a first surface (7) being fixed on the frame (D) according to a plane which is substantially vertical and parallel to the pivoting axis (X) of the leaf (B), and a second surface (13) being fixed on the leaf (B) substantially according to an arc of a circle surrounding said pivoting axis which is formed for example by hinges with vertical axis.
3. Device according to claims 1 or 2, characterized in that the toothed elements or surfaces (7, 13) are each made of an elastic material, e. g. an acetal resin as regards the surface which is fixed on the frame, and a polyamide as regards the surface which is fixed on the leaf.
4. Device according to one of claims 1 to 3, characterized in that the relative position of both toothed surfaces respectively fixed on the frame and on the leaf is such that the number of meshing teeth (8, 14) and thus the holding torque become greater as the aperture angle of the leaf (B) becomes wider.
5. Device according to one of claims 1 to 4, characterized in that the toothed surfaces (7, 13) are fixed and stretched respectively on the frame and on the leaf by means of studs or similar (17) clipped into holes provided in this frame and in this leaf.
6. Device according to one of the preceding claims, characterized in that the ends (15, 16) of the toothed surface (13) fixed on the leaf (B) are not toothed and present two turned-in flanges (15a, 16a) which form between each other an angle essentially equal to 90° after said surface has been fixed on said leaf.
7. Device according to one of the preceding claims, characterized in that at least the fixing of the toothed surface (13) on the leaf (B) is adjustable in order to permit a preadjustment of the stretching or stressing thereof.
8. Device according to claim 6, characterized in that one (15) of said ends of the toothed surface fixed on the leaf is provided with at least one thrust (21) which co-operates with the frame in order to define a maximum aperture angle for the leaf.
