Description

La présente invention a essentiellement pour objet un dispositif de retenue de porte en position d'ouverture.The present invention essentially relates to a door retaining device in the open position.

On a déjà proposé des dispositifs de retenue, notamment pour portes de véhicules automobiles, qui permettent le maintien en position ouverte de la porte afin de faciliter l'accès ou l'évacuation de l'habitacle du véhicule.Retaining devices have already been proposed, in particular for motor vehicle doors, which allow the door to be kept in the open position in order to facilitate access to or evacuation from the vehicle interior.

Ces dispositifs opposent lors de la fermeture de la porte une certaine résistance en début de fermeture de la porte à partir de sa pleine ouverture. Ils comprennent par exemple un élément élastiquement déformable associé à la porte ou à l'encadrement de cette porte, et qui peut être comprimé lors du mouvement de la porte pour créer un point dur qui, après franchissement, permet notamment le maintien de la porte en position de pleine ouverture.These devices oppose when closing the door a certain resistance at the start of closing the door from its full opening. They include for example an elastically deformable element associated with the door or the frame of this door, and which can be compressed during the movement of the door to create a hard point which, after crossing, in particular allows the maintenance of the door in full opening position.

Toutefois, les dispositifs du genre ci-dessus et téls que décrits par exemple dans le FR-A-2339043 présentent un certain nombre d'inconvénients. Ils sont d'une manière générale, compliqués, fragiles et sensibles à l'usure, si bien qu'à la longue leur fiabilité est loin d'être satisfaisante.However, the devices of the above kind and tels as described for example in FR-A-2339043 have a number of drawbacks. They are generally complicated, fragile and sensitive to wear, so that in the long term their reliability is far from satisfactory.

La présente invention a pour but de remédier notamment aux inconvéniens ci-dessus en proposant un dispositif de retenue de porte perfectionné, qui est d'une conception mécanique particulièrement simple et robuste, et qui de plus présente une excellente fiabilité de fonctionnement même après un temps très long, c'est-à-dire après un très grand nombre de mouvements de pivotement de la porte autour de ses charnières.The object of the present invention is to remedy the above drawbacks in particular by proposing an improved door retention device, which is of a particularly simple and robust mechanical design, and which moreover has excellent operating reliability even after a period of time. very long, that is to say after a very large number of pivoting movements of the door around its hinges.

A cet effet, l'invention a pour objet un dispositif de retenue de porte, applicable notamment aux portes d'un véhicule automobile, et du type comprenant un élément élastiquement déformable associé à ladite porte ou à l'encadrement de cette porte et qui peut être comprimé lors du mouvement de la porte pour créer un point dur qui, après franchissement, permet notamment le maintien de la porte en position de pleine ouverture, ce dispositif étant essentiellement caractérisé en ce que l'élément élastiquement déformable comprend une première partie montée de manière ajustable dans un socle et une deuxième partie coiffée par un organe de friction prenant appui par glissement et sans roulement sur l'encadrement si le socle est solidaire de la porte, ou bien sur la porte si le socle est solidaire de l'encadrement.To this end, the subject of the invention is a door retaining device, applicable in particular to the doors of a motor vehicle, and of the type comprising an elastically deformable element associated with said door or with the frame of this door and which can be compressed during the movement of the door to create a hard point which, after crossing, allows in particular the maintenance of the door in the fully open position, this device being essentially characterized in that the elastically deformable element comprises a first part mounted of adjustable manner in a base and a second part capped by a friction member bearing by sliding and without rolling on the frame if the base is secured to the door, or on the door if the base is secured to the frame.

On précisera encore ici que, suivant une autre caractéristique de l'invention, le socle précité comprend une portion formant boîtier tubulaire dans lequel est logée la première partie précitée de l'élément élastiquement déformable. ,It will also be specified here that, according to another characteristic of the invention, the aforementioned base comprises a portion forming a tubular housing in which the first aforementioned part of the elastically deformable element is housed. ,

Selon encore une autre caractéristique de, l'invention, l'organe de friction associé à l'élément élastiquement déformable est attelé ou non au socle précité.According to yet another characteristic of the invention, the friction member associated with the elastically deformable element is coupled or not to the aforementioned base.

Suivant un exemple de réalisation, l'orange de friction est constitué par une languette articulée sur le socle et constituée de préférence par deux volets successifs articulés entre deux. Le socle et la languette sont avantageusement réalisés en une seule pièce moulée en matériau synthétique, tandis que les articulations de la languette sont obtenues par un amincissement de matière.According to an exemplary embodiment, the friction orange is constituted by a tongue articulated on the base and preferably constituted by two successive flaps articulated between two. The base and the tongue are advantageously made in a single piece molded from synthetic material, while the articulations of the tongue are obtained by a thinning of material.

On notera encore ici que le socle précité peut comporter des butées de limitation du débattement de la languette.It will also be noted here that the aforementioned base may include stops for limiting the movement of the tongue.

Suivant un autre mode de réalisation, l'organe de friction est constitué par un pion indépendant du socle et fixé par clippage ou analogue en bout de la deuxième partie précitée de l'élément élastiquement déformable.According to another embodiment, the friction member is constituted by a pin independent of the base and fixed by clipping or the like at the end of the aforementioned second part of the elastically deformable element.

Le pion précité comporte de préférence un agencement cruciforme de cloisons permettant son verrouillage en rotation dans l'élément élastiquement déformable.The aforementioned pin preferably comprises a cruciform arrangement of partitions allowing it to be locked in rotation in the elastically deformable element.

Suivant encore une autre caractéristique de l'invention, l'ajustage ou le réglage de l'élément élastiquement déformable dans le boîtier tubulaire du socle est obtenu par une rampe hélicoïdale.According to yet another characteristic of the invention, the adjustment or the adjustment of the elastically deformable element in the tubular casing of the base is obtained by a helical ramp.

On ajoutera encore ici que, suivant une réalisation préférée, l'élément élastiquement déformable est constitué par un bloc sensiblement cylindrique en un matériau élastomère, caoutchouteux ou analogue qui, après montage, fait saillie du socle pour ainsi procurer une zone de compression par l'intermédiaire de l'organe de friction interposé entre ce bloc et la porte ou bien l'encadrement de cette porte suivant le montage du socle sur l'un ou l'autre de ces deux éléments.It will also be added here that, according to a preferred embodiment, the elastically deformable element consists of a substantially cylindrical block of an elastomeric, rubbery material or the like which, after assembly, projects from the base so as to provide a compression zone for the intermediate the friction member interposed between this block and the door or the frame of this door following the mounting of the base on one or the other of these two elements.

Mais d'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit et sse réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels :However, other characteristics and advantages of the invention will appear better in the detailed description which follows and refers to the appended drawings, given solely by way of example, and in which:

Les figures 1 et 2 sont des vues en perspective, suivant deux angles différents, d'une première réalisation de dispositif de retenue de porte, conforme aux principes de l'invention;Figures 1 and 2 are perspective views, from two different angles, of a first embodiment of a door retaining device, in accordance with the principles of the invention;

La figure 3 est une vue en perspective du dispositif des figures 1 et 2, lequel est équipé de butées de limitation du débattement de la languette associée au socle;Figure 3 is a perspective view of the device of Figures 1 and 2, which is equipped with stops for limiting the movement of the tongue associated with the base;

Les figures 4 et 5 sont des vues schématiques du dispsitif en position montée sur une porte, la figure 4 montrant cette porte en position fermée, et la figure 5 illustrant le franchissement du point dur lorsqu'on ouvre ou on ferme la porte;Figures 4 and 5 are schematic views of the device in the mounted position on a door, Figure 4 showing this door in the closed position, and Figure 5 illustrating the crossing of the hard point when the door is opened or closed;

La figure 6 est une vue en perspective éclatée d'un autre mode de réalisation du dispositif conforme à l'invention;Figure 6 is an exploded perspective view of another embodiment of the device according to the invention;

La figure 7 est une vue en coupe verticale partielle de ce dispositif, etFIG. 7 is a partial vertical sectional view of this device, and

La figure 8 illustre schématiquement diverses positions d'une porte équipée du dispositif des figures 6 et 7, par rapport à la structure d'encadrement de cette porte.Figure 8 schematically illustrates various positions of a door equipped with the device of Figures 6 and 7, relative to the frame structure of this door.

Suivant l'exemple de réalisation représenté sur les figures 1 à 5, un dispositif de retenue de porte conforme à l'invention comprend essentiellement un socle 1 dans lequel est monté de manière réglable un élément 2 élastiquement déformable et réalisé par exemple en élastomètre ou en caoutchouc dur.According to the embodiment shown in Figures 1 to 5, a door retaining device according to the invention essentially comprises a base 1 in which an elastically deformable element 2 is mounted in an adjustable manner and made for example of an elastometer or of hard rubber.

Cet élément élastiquement déformable 2 présente par exemple la forme d'un bloc cylindrique et comporte une première partie ou extrémité inférieure 3 montée de manière réglable dans une portion 4 du socle 1 forme en quelque sorte un boîtier tubulaire, ainsi qu'une deuxième partie 5 coiffée par un organe de friction 6.This elastically deformable element 2 has for example the shape of a cylindrical block and comprises a first part or lower end 3 mounted in an adjustable manner in a portion 4 of the base 1 in a way forms a tubular housing, as well as a second part 5 capped by a friction member 6.

Cet organe de friction 6 est attelé au socle 1 et est constitué par une languette articulée sur ledit socle et formée de deux volets successifs 7a et 7b. Plus précisément, le volet 7a forme en quelque sorte un plateau coiffant l'extrémité supérieure 5 du bloc compression 2 et est articulé au volet 7b par un cissement de matière 6. Le volet 7b est également articulé au socle 1 par un amincissement de matière 9.This friction member 6 is coupled to the base 1 and is constituted by a tongue articulated on said base and formed by two successive flaps 7a and 7b. More specifically, the flap 7a somehow forms a plate covering the upper end 5 of the compression block 2 and is articulated to the flap 7b by a cisse of material 6. The flap 7b is also articulated to the base 1 by a thinning of material 9 .

Le socle 1 et la languette formée par les volets 7a et 7b peuvent avantageusement être réalisés en une seule pièce en un matériau synthétique approprié, de sorte que les amincissements 8 et 9 viennent de moulage avec l'ensamble de la pièce.The base 1 and the tongue formed by the flaps 7a and 7b can advantageously be made in one piece from a suitable synthetic material, so that the thinning 8 and 9 are molded with the whole of the piece.

Le socle 1 comporte une semmelle 10 avec une boutonnière 11 permettant la fixation, tandis que des nervures de fraidissement 12, bien visibles sur la figure 2, peuvent être prévues pour rigidifier le volet ou plateau 7b qui coiffe le bloc élastique 2.The base 1 comprises a sole 10 with a buttonhole 11 allowing the fixing, while the stiffening ribs 12, clearly visible in FIG. 2, can be provided to stiffen the flap or plate 7b which covers the elastic block 2.

Comme on le voit bien sur la figure 3, il est possible de prévoir des butées 13 qui son solidaires du socle 1 et permettent de limiter le débattement de la languette formée par les volets successifs 7a et 7b, comme on l'expliquera plus loin.As can be seen in FIG. 3, it is possible to provide stops 13 which are integral with the base 1 and make it possible to limit the movement of the tongue formed by the successive flaps 7a and 7b, as will be explained below.

Le bloc élastiquement déformable 2 comporte sur sa périphérie une rampe hélicoïdale 2a qui coopère avec une rampe correspondante prévue à l'interieur de la portion ou boîtier tubulaire 4 du socle 1. Ainsi, par rotation du bloc 2 dans la portion 4 on pourra augmenter ou réduire sa saillie par rapport au socle, ce qui permettra par conséquent le réglage de la dureté de reponsendu bloc élastiquement déformable 2.The elastically deformable block 2 comprises on its periphery a helical ramp 2a which cooperates with a corresponding ramp provided inside the tubular portion or casing 4 of the base 1. Thus, by rotation of the block 2 in the portion 4 it will be possible to increase or reduce its projection relative to the base, which will therefore allow adjustment of the hardness of the resiliently deformable block 2.

Comme on le voit sur les figures 4 et 5, le dispositif qui vient d'être décrit est disposé entre une porte 14, sur laquelle il est par exemple fixé, et une structure 15 d'encadrement de cette porte. Ainsi, le volet ou plateau 7a se trouve interposé entre le bloc élastique 2 et l'encadrement 15 sur lequel il prend appui.As can be seen in FIGS. 4 and 5, the device which has just been described is disposed between a door 14, on which it is for example fixed, and a structure 15 for framing this door. Thus, the flap or plate 7a is interposed between the elastic block 2 and the frame 15 on which it is supported.

Lorsqu'on ouvre la porte, elle pivote par rapport à l'encadrement 15, comme on le voit bien sur la figur 5, et le jeu entre la porte et l'encadrement varie. Plus précisément, lors du passage du bloc de compression 2 devant l'arête arrondie 15a de l'encadrement 15, ledit bloc va se comprimer pour créer un point dur qui disparaîtra au-delà de l'arête 15a, c'est-à-dire lorsque la porte sera en position de pleine ouverture. On remarquera ici que le volet 7a, constitué d'un matériau à coefficient de frottement approprié, encaissera partiellement l'effort tangentiel de friction sur l'encadrement 15 lors de la rotation de la porte, tandis que le volet 7b, limité en débattement par les butées 13, permettra avantageusement au volet 7a de se maintenir en position interposée entre le bloc élastique 2 et l'encadrement 15.When the door is opened, it pivots relative to the frame 15, as can be seen in FIG. 5, and the clearance between the door and the frame varies. More precisely, during the passage of the compression block 2 in front of the rounded edge 15a of the frame 15, said block will compress to create a hard point which will disappear beyond the edge 15a, that is to say tell when the door will be in the fully open position. It will be noted here that the flap 7a, made of a material with an appropriate coefficient of friction, will partially collect the tangential friction force on the frame 15 during the rotation of the door, while the flap 7b, limited in movement by the stops 13, will advantageously allow the flap 7a to remain in the interposed position between the elastic block 2 and the frame 15.

On comprend de tout ce qui précède que, lorsqu'on ouvre ou lorsqu'on ferme la porte, on passera par un point dur correspondant à une compression maximum du bloc élastique 2, étant bien entendu que l'effort de compression sur ledit bloc sera réduit lorsque ladite porte sera notamment en position de pleine ouverture, ce qui permettra son maintien dans une telle position.It is understood from all of the above that, when the door is opened or closed, it will pass through a hard point corresponding to maximum compression of the elastic block 2, it being understood that the compression force on said block will be reduced when said door is in particular in the fully open position, which will allow it to be maintained in such a position.

Le mode de réalisation du dispositif de retenue conforme à l'invention et illustré par les figures 6 à 8 utilise les mêmes éléments essentiels que ceux décrits à propos de la réalisation des figures 1 à 5.The embodiment of the retaining device according to the invention and illustrated by FIGS. 6 to 8 uses the same essential elements as those described in connection with the embodiment of FIGS. 1 to 5.

En effet, on voit que la réalisation représentée sur les figures 6 à 8 comprend un socle 1 avec semelle 10, un bloc élastiquement déformable 2 dont la partie inférieur 3 se loge dans une portion tubulaire 4 dudit socle, et dont la partie supérieure 5 est coiffée par un organe de friction 6. Comme précédemment décrit, la périphérie du bloc comprend une rampe hélicoïdale 2a coopérant avec une rampe correspondante 4a ménagée dans l'a portion tubulaire du socle 1, afin de pouvoir ajuster ou régler la saillie du bloc élastique 2.Indeed, we see that the embodiment shown in Figures 6 to 8 comprises a base 1 with sole 10, an elastically deformable block 2 whose lower part 3 is housed in a tubular portion 4 of said base, and whose upper part 5 is capped by a friction member 6. As previously described, the periphery of the block comprises a helical ramp 2a cooperating with a corresponding ramp 4a formed in the tubular portion of the base 1, in order to be able to adjust or adjust the projection of the elastic block 2 .

Mais ici, l'orange de friction 6 est tout simplement constitué par un pion circulaire 16 dont la face supérieure est légèrement bombée ou convexe et dont la face inférieure comporte un petit axe central 17 muni de stries ou analogues 18 pour permettre l'accrochage par clippage ou introduction forcée à l'intérieur d'un alésage ou analogue 19 pratiqué dans l'axe du bloc élastiqument déformable 2.But here, the friction orange 6 is quite simply constituted by a circular pin 16, the upper face of which is slightly convex or convex and the lower face of which has a small central axis 17 provided with striations or the like 18 to allow hooking by clipping or forced insertion inside a bore or the like 19 made in the axis of the elastically deformable block 2.

Le pion circulaire 6 comporte également sur le dessous un agencement cruciforme de cloisons 20 permettant le verrouillage en rotation du pion dans le bloc 2. On a montré en 21 sur la figure 6 des fentes dans lesquelles pénètrent les 20 du pion 6.The circular pin 6 also has on the bottom a cruciform arrangement of partitions 20 allowing the pin to be locked in rotation in the block 2. At 21 in FIG. 6, slots have been shown in which the 20s of the pin 6 penetrate.

Le fonctonnement de la réalisation qui vient d'être décrite sera brièvement expliqué en se reportant au schéma de la figure 8, car ce fonctionnement est sensiblement le même que celui de la réalisation des figures 1 à 3.The operation of the embodiment which has just been described will be briefly explained with reference to the diagram in FIG. 8, since this operation is substantially the same as that of the embodiment in FIGS. 1 to 3.

Lorsqu'on fait pivoter la porte autour de ses charnières pour l'ouvrir, le bloc élastiquement déformable 2, solidaire de là porte 14, décrit un arc de cercle et demeure en contrainte d'appui sur le profil de la structure d'encadrement 15, en passant par une position de compression maximum ou de point dur en 15a, ce après quoi le bloc 2 reprendra sensiblement sa forme initiale en position de pleine ouverture de la porte et cette dernière sera retenue dans cette position. On comprend tout cela en se reportant à la figure 8 montrant trois positions 20, 30 et 40 du bloc 2, ces positions correspondant respectivement à la position fermée, intermédiaire, et pleinement ouverte de la porte 14.When the door is pivoted around its hinges to open it, the elastically deformable block 2, integral with the door 14, describes an arc of a circle and remains in bearing stress on the profile of the framing structure 15 , passing through a position of maximum compression or hard point at 15a, after which the block 2 will substantially resume its initial shape in the fully open position of the door and the latter will be retained in this position. We understand all this by referring to FIG. 8 showing three positions 20, 30 and 40 of block 2, these positions corresponding respectively to the closed, intermediate, and fully open position of the door 14.

On insistera ici sur le fait que, dans les deux modes de réalisation qui ont été décrits, la compression maximum du bloc 2 créant le point dur, c'est-à-dire l'effet de retenue désiré par passage sur l'aréte 15a de l'encadrement 15, peut être réglée par la simple rotation du bloc 2 dans le réceptacle 4 du socle 1. Egalement, on pourrait prévoir un montage du socle 1 suivant une disposition inverse de celle representee, c'est-à-dire que ledit socle serait solidaire non plus de la porte, mais de la structure d'encadrement de cette porte.It will be emphasized here that, in the two embodiments which have been described, the maximum compression of the block 2 creating the hard point, that is to say the desired retaining effect by passing over the edge 15a of the frame 15, can be adjusted by simply rotating the block 2 in the receptacle 4 of the base 1. Also, one could provide a mounting of the base 1 in an arrangement opposite to that shown, that is to say that said base would no longer be integral with the door, but with the framing structure of this door.

C'est dire que l'invention n'est nullement limitée aux modes de réalisation décrits et illustrés qui n été donnés qu'à titre d'exemples.This means that the invention is in no way limited to the embodiments described and illustrated which have been given only by way of examples.

Ainsi, on pourrait très bien prévoir, sans sortir du cadre de l'invention, une butée entre l'organe de friction 6 et la partie superieure du socle 1 recevant le bloc élastiquement déformable 2, ladite butée limitant la compression du bloc 2 pour une position correspondant sensiblement au passage du point dur 15a.Thus, one could very well provide, without departing from the scope of the invention, a stop between the friction member 6 and the upper part of the base 1 receiving the elastically deformable block 2, said stop limiting the compression of block 2 for a position corresponding substantially to the passage of the hard point 15a.
