Description

L'invention concerne un dispositif de raccordement coaxial entre un premier organe rotatif et un deuxième organe rotatif montés à rotation respectivement autour d'un premier axe et d'un deuxième axe, pour solidariser ces organes en rotation avec leurs axes respectifs coaxiaux.The invention relates to a coaxial connection device between a first rotary member and a second rotary member rotatably mounted around a first axis and a second axis, to secure these rotating members with their respective coaxial axes.

Un dispositif de ce type peut être utilisé en particulier dans un véhicule automobile pour assurer un raccordement coaxial entre un premier organe susceptible d'être entraíné en rotation par des moyens de commande et un deuxième organe susceptible de commander une pièce mobile.A device of this type can be used in particular in a motor vehicle to provide a connection coaxial between a first organ capable of being driven in rotation by control means and a second member likely to order a moving part.

A titre d'exemple, le premier organe rotatif peut être un organe menant réalisé sous la forme d'un câble et le deuxième organe rotatif un organe mené réalisé sous la forme d'un levier, secteur denté ou analogue. Ce dernier peut alors commander directement ou indirectement le déplacement d'une pièce mobile, par exemple d'un volet d'air dans un appareil de chauffage et/ou climatisation de véhicule automobile.By way of example, the first rotary member can be a the driving member produced in the form of a cable and the second rotary member a driven member produced in the form of a lever, toothed sector or the like. The latter can then directly or indirectly order the movement of a moving part, for example an air shutter in an appliance motor vehicle heating and / or air conditioning.

On connaít déjà des dispositifs de raccordement coaxial de ce type, dans lesquels les deux organes rotatifs possèdent des moyens de connexion, par exemple à encliquetage, qui coopèrent entre eux par un mouvement dans le sens axial.We already know coaxial connection devices of this type, in which the two rotary members have connection means, for example snap-in, which cooperate between them by a movement in the axial direction.

Cette solution a notamment pour inconvénient que la connexion entre les deux organes rotatifs est généralement difficile à réaliser en raison de la faible souplesse ou flexibilité de l'un ou l'autre des organes rotatifs. Ceci est le cas notamment lorsque l'un des deux organes est un câble, dont la flexibilité dans le sens axial est faible.One of the disadvantages of this solution is that the connection between the two rotary members is generally difficult to achieve due to the low flexibility or flexibility of either of the rotary members. This is the case in particular when one of the two members is a cable, the flexibility in the axial direction is low.

En outre, de tels dispositifs de raccordement permettent généralement deux positions de raccordement espacées angulairement à 180°, si bien qu'il existe toujours un risque que le raccordement ne soit pas effectué correctement.In addition, such connecting devices allow generally two angularly spaced connection positions 180 °, so there is always a risk that the connection is not made correctly.

L'invention a notamment pour but de surmonter les inconvénients précités.The object of the invention is in particular to overcome the drawbacks cited above.

Elle propose à cet effet un dispositif de raccordement coaxial du type défini en introduction, dans lequel le premier organe rotatif est muni, à une extrémité, d'un coulisseau s'étendant perpendiculairement au premier axe de rotation, dans lequel le deuxième organe rotatif est muni, à une extrémité, d'un bloc à glissière s'étendant perpendiculairement au deuxième axe de rotation et propre à recevoir à coulissement le coulisseau, et dans lequel des moyens de verrouillage sont prévus pour immobiliser mutuellement le bloc à glissière et le coulisseau, ce qui permet de raccorder mutuellement lesdits organes rotatifs dans une position angulaire indexée définie.To this end, it offers a connection device coaxial of the type defined in the introduction, in which the first rotary member is provided, at one end, with a slide extending perpendicular to the first axis of rotation, in which the second rotary member is provided, at one end of a slide block extending perpendicularly to the second axis of rotation and suitable for receiving at sliding the slide, and in which means for locking are provided to immobilize each other the slide block and slide, allowing connection mutually said rotary members in a position defined indexed angular.

Ainsi, contrairement aux solutions habituelles, le dispositif de l'invention procure un raccordement des deux organes rotatifs par un mouvement dans le sens radial, c'est-à-dire perpendiculairement aux axes de rotation respectifs des deux organes.So, unlike the usual solutions, the device of the invention provides a connection of the two members rotating by a movement in the radial direction, that is to say perpendicular to the respective axes of rotation of the two organs.

En conséquence, il est possible d'effectuer un tel raccordement même si l'un et/ou l'autre des deux organes rotatifs possèdent une faible flexibilité dans le sens axial.Consequently, it is possible to make such a connection even if one and / or the other of the two rotary members have low flexibility in the axial direction.

Le dispositif de l'invention offre en outre l'avantage que le raccordement peut s'effectuer selon une procédure dite en aveugle, en garantissant que les deux organes se trouvent ensuite raccordés et verrouillés dans une position angulaire définie, ce qui permet de procurer un raccordement indexé.The device of the invention also offers the advantage that the connection can be made according to a procedure known as blind, ensuring that both organs are found then connected and locked in an angular position defined, which provides an indexed connection.

Dans une forme de réalisation préférée de l'invention, le coulisseau comporte deux nervures parallèles opposées propres à s'engager dans deux rainures parallèles en vis à vis, de formes conjuguées, que comporte le bloc à glissière. In a preferred embodiment of the invention, the slide has two clean opposite parallel ribs to engage in two parallel grooves opposite, of conjugate forms, which includes the slide block.

Les deux nervures précitées sont de préférence formées par deux bords longitudinaux parallèles d'une platine faisant partie du coulisseau.The two aforementioned ribs are preferably formed by two parallel longitudinal edges of a plate making part of the slide.

Les deux rainures précitées sont avantageusement formées dans deux parois longitudinales du bloc à glissière, celui-ci définissant un boítier partiellement ouvert.The two aforementioned grooves are advantageously formed in two longitudinal walls of the slide block, this defining a partially open housing.

Les moyens de verrouillage précités sont avantageusement du type à encliquetage.The aforementioned locking means are advantageously snap-in type.

Ainsi, ces moyens de verrouillage peuvent comprendre une languette déformable qui prolonge le coulisseau et qui est munie d'un rebord transversal propre à s'engager derrière une barrette faisant partie du bloc à glissière.Thus, these locking means can include a deformable tongue which extends the slide and which is provided with a transverse rim suitable for engaging behind a bar forming part of the slide block.

Cette barrette relie avantageusement les deux parois longitudinales du bloc à glissière.This bar advantageously connects the two longitudinal walls of the slide block.

Dans une forme de réalisation préférée de l'invention, le bloc à glissière comporte une face ouverte d'entrée délimitée entre les deux parois longitudinales pour l'introduction du coulisseau, une face ouverte de sortie située à l'opposé de la face d'entrée pour le verrouillage et une face ouverte d'extrémité pour le passage de l'extrémité du premier organe rotatif.In a preferred embodiment of the invention, the slide block has a defined open entry face between the two longitudinal walls for the introduction of the slide, an open exit face located opposite the entry side for locking and one open side end for the passage of the end of the first member rotary.

Selon une autre caractéristique de l'invention, le bloc à glissière et le coulisseau comprennent des moyens de butée coopérants pour limiter l'introduction du coulisseau dans le bloc à glissière dans une position de butée en laquelle le premier axe et le deuxième axe sont mutuellement alignés.According to another characteristic of the invention, the block slide and slide comprise stop means cooperating to limit the introduction of the slide into the slide block in a stop position in which the first axis and the second axis are mutually aligned.

Ces moyens de butée comprennent avantageusement une face frontale du coulisseau et une face postérieure de la barrette précitée. These abutment means advantageously include a face front of the slide and a rear face of the bar cited above.

Dans une forme de réalisation préférée de l'invention, le premier organe rotatif est un organe menant, tandis que le deuxième organe rotatif est un organe mené.In a preferred embodiment of the invention, the first rotary organ is a driving organ, while the second rotary member is a driven member.

A titre d'exemple, le premier organe rotatif peut être un organe filiforme tel qu'un câble, une tige ou analogue, tandis que le deuxième organe rotatif peut être un organe radial, tel qu'un levier, un secteur denté ou analogue.By way of example, the first rotary member can be a filiform organ such as a cable, a rod or the like, while the second rotary member can be a member radial, such as a lever, a toothed sector or the like.

Dans la description détaillée qui suit, faite seulement à titre d'exemple, on se réfère aux dessins annexés, sur lesquels :

  • la figure 8 est une vue en coupe selon la ligne VIII-VIII de la figure 7.
In the detailed description which follows, given solely by way of example, reference is made to the appended drawings, in which:
  • Figure 1 is a perspective view of a device according to the invention used to connect a rotary cable to a rotary toothed sector in a control mechanism of a heating and / or air conditioning apparatus of a motor vehicle;
  • Figure 2 is a perspective view of the rotary cable and the slide;

  • Figure 7 is a partial view similar to Figure 5, without the slide; and
  • FIG. 8 is a sectional view along line VIII-VIII of FIG. 7.

On se réfère tout d'abord à la figure 1 qui représente un dispositif 10 pour réaliser un raccordement coaxial entre un premier organe rotatif 12 et un deuxième organe rotatif 14 montés à rotation respectivement autour d'un premier axe X1 et d'un deuxième axe X2. Dans l'exemple, le deuxième organe rotatif 14 est un secteur denté comportant des dents 16 et portant en outre deux pions 18.We first refer to Figure 1 which represents a device 10 for making a coaxial connection between a first rotary member 12 and a second rotary member 14 rotatably mounted respectively around a first axis X1 and a second axis X2. In the example, the second organ rotary 14 is a toothed sector comprising teeth 16 and additionally carrying two pawns 18.

L'organe rotatif 14 est porté à l'extérieur d'une paroi 20 d'un boítier, laquelle porte également un autre secteur denté 22 muni de dents 24 susceptibles d'engrener avec les dents 16 et portant également une voie de came 26. Cette voie de came 26 est propre à coopérer avec l'un ou l'autre des pions 18 lorsque les dents 16 et 24 sont désengrenées.The rotary member 14 is carried outside of a wall 20 of a case, which also carries another toothed sector 22 with teeth 24 capable of meshing with teeth 16 and also carrying a cam track 26. This cam track 26 is capable of cooperating with one or the other of the pawns 18 when the teeth 16 and 24 are disengaged.

Le secteur denté 22 est lié en rotation à une commande d'un pulseur (non représenté) faisant partie d'un appareil de chauffage et/ou climatisation de véhicule automobile.The toothed sector 22 is linked in rotation to a command of a pulser (not shown) forming part of a motor vehicle heating and / or air conditioning.

Le câble rotatif 12 peut être entraíné en rotation sur son axe X1, dans un sens ou dans l'autre pour entraíner le secteur denté 22, cet entraínement se faisant soit par coopération des dents 16 et 24, soit par coopération de l'un et/ou l'autre des pions 18 et de la came 26.The rotary cable 12 can be rotated on its axis X1, in one direction or the other to drive the toothed sector 22, this training being done either by cooperation of teeth 16 and 24, either by cooperation of one and / or the other of the pins 18 and of the cam 26.

Comme on le voit mieux sur les figures 2 et 3, le câble 12 est muni, à une extrémité 28, d'un coulisseau 30, encore appelé chariot, qui s'étend perpendiculairement à l'axe X1. Ce coulisseau, comme on le verra plus loin, est propre à coulisser dans une direction Y1 (figure 2) perpendiculaire à l'axe X1. Le coulisseau 30 comporte un bloc parallélépipédique 32 auquel est rattaché un manchon 34 dans lequel est solidarisée l'extrémité 28 du câble.As best seen in Figures 2 and 3, the cable 12 is provided, at one end 28, with a slide 30, again called a carriage, which extends perpendicular to the X1 axis. This slide, as we will see later, is specific to slide in a direction Y1 (figure 2) perpendicular to the X1 axis. The slide 30 has a parallelepiped block 32 to which is attached a sleeve 34 in which is secured the end 28 of the cable.

Le bloc 32 comporte latéralement deux nervures parallèles 36 faisant partie d'une platine 38 dépassant d'une face frontale 40 du bloc 32. Cette platine se prolonge vers l'avant pour former une languette déformable de verrouillage 42. Cette languette prolonge le coulisseau et est munie d'un rebord transversal 44 (figures 2 et 3) dont le rôle sera expliqué plus loin.The block 32 laterally comprises two parallel ribs 36 forming part of a plate 38 projecting from a front face 40 of block 32. This plate extends forward for form a deformable locking tab 42. This tongue extends the slide and has a rim transverse 44 (Figures 2 and 3) whose role will be explained further.

Les nervures 36 ont un profil quadrangulaire et sont dirigées toutes les deux dans la direction de l'axe Y1 précité.The ribs 36 have a quadrangular profile and are directed both in the direction of the aforementioned Y1 axis.

Le coulisseau 30 est destiné à être reçu dans un bloc à glissière 46 réalisé d'une seule pièce à une extrémité du secteur denté 14, de préférence par moulage en matière plastique (figures 4 à 8).The slide 30 is intended to be received in a block to slide 46 made in one piece at one end of the toothed sector 14, preferably by molding in material plastic (Figures 4 to 8).

Ce bloc à glissière comporte deux parois longitudinales parallèles 48 situées symétriquement de part et d'autre de l'axe X2 et dans lesquelles sont ménagées respectivement deux rainures parallèles en vis à vis 50 (figure 8). Ces rainures ont des formes conjuguées de celles des nervures 36 pour permettre un emmanchement du coulisseau 30 dans les glissières formées par les rainures 50.This slide block has two longitudinal walls parallel 48 located symmetrically on either side of axis X2 and in which two are arranged respectively parallel grooves opposite 50 (Figure 8). These grooves have shapes combined with those of the ribs 36 for allow a fitting of the slider 30 in the slides formed by the grooves 50.

Le bloc à glissière 46 comporte une face ouverte d'entrée 52 délimitée entre les deux parois longitudinales 50 pour permettre l'introduction du coulisseau 30, une face ouverte de sortie 54 située à l'opposé de la face d'entrée pour permettre le passage de la languette de verrouillage 42, et une face ouverte d'extrémité 56 pour le passage de l'extrémité 28 du câble 12 (figure 7).The slide block 46 has an open inlet face 52 delimited between the two longitudinal walls 50 for allow the introduction of the slide 30, an open face outlet 54 located opposite the inlet face for allow passage of the locking tab 42, and an open end face 56 for the passage of the end 28 of cable 12 (Figure 7).

Les parois 48 sont réunies entre elles, à la jonction des faces 54 et 56, par une barrette transversale 58 susceptible de coopérer avec le rebord transversal 44 de la languette déformable 42 (figure 5).The walls 48 are joined together, at the junction of the sides 54 and 56, by a transverse bar 58 capable to cooperate with the transverse edge 44 of the tongue deformable 42 (Figure 5).

Pour réaliser la connexion entre les organes rotatifs 12 et 14, on place le coulisseau 30 (côté languette 42) en regard de la face d'entrée 52 du bloc à glissière 46, comme représenté en trait interrompu sur la figure 5. Ceci peut se faire par exemple en déplaçant latéralement le câble par un mouvement pendulaire. Ensuite, il suffit de déplacer le coulisseau dans le sens de la flèche F (figure 5) pour que les nervures 36 du coulisseau s'engagent dans les rainures 50 du bloc à glissière 46, jusqu'à ce que la face frontale 40 du coulisseau vienne en butée contre une face postérieure 60 de la barrette. Dans cette position, les axes X1 et X2 sont alignés.To make the connection between the rotating members 12 and 14, place the slide 30 (tongue side 42) opposite of the input face 52 of the slide block 46, as shown in broken lines in Figure 5. This can be done for example by moving the cable laterally by a pendulum movement. Then just move the slide in the direction of arrow F (figure 5) so that the ribs 36 of the slider engage in the grooves 50 of the slide block 46, until the front face 40 of the slide comes into abutment against a rear face 60 of the bar. In this position, the axes X1 and X2 are aligned.

Par ailleurs, au cours du mouvement d'introduction, la languette s'est déformée pour permettre à son rebord transversal 44 de passer sous la barrette 58 et de s'engager ensuite derrière celle-ci pour assurer un verrouillage par encliquetage. On procure ainsi un raccordement coaxial des organes 12 et 14, avec une position angulaire indexée offrant une seule possibilité de raccordement.Furthermore, during the introductory movement, the tongue has deformed to allow its transverse edge 44 to go under the bar 58 and to engage then behind it to ensure locking by snap-in. This provides a coaxial connection of organs 12 and 14, with an indexed angular position offering only one connection possibility.

Dans l'exemple représenté, le secteur denté 14 comporte une tige cylindrique 62 engagée dans un fût cylindrique 64 solidaire de la paroi 20 du boítier (figure 5). De même, le secteur denté 22 comporte une tige cylindrique 66 montée à rotation dans un fût cylindrique 68 dépendant de cette paroi 20.In the example shown, the toothed sector 14 includes a cylindrical rod 62 engaged in a cylindrical barrel 64 secured to the wall 20 of the housing (Figure 5). Likewise, the toothed sector 22 comprises a cylindrical rod 66 mounted at rotation in a cylindrical barrel 68 depending on this wall 20.

Le raccordement des organes rotatifs 12 et 14 précités peut s'effectuer de façon particulièrement simple sur une chaíne de fabrication, automatisée ou non, dans l'industrie automobile. Si les deux organes doivent être désaccouplés, il suffit d'appuyer sur la languette 44 pour permettre le déverrouillage puis de dégager le coulisseau du bloc à glissière par un mouvement inverse du mouvement d'introduction défini précédemment.The connection of the aforementioned rotary members 12 and 14 can be carried out in a particularly simple way on a chain manufacturing, automated or not, in the automotive industry. If the two organs are to be uncoupled, it just press tab 44 to allow unlocking then releasing the slide from the block to slide by a reverse movement of the introduction movement previously defined.

Bien entendu, l'invention n'est pas limitée à la forme de réalisation décrite précédemment à titre d'exemple et s'étend à d'autres variantes.Of course, the invention is not limited to the form of embodiment described above by way of example and extends to other variants.
