Abstract

The retractable knob has the body of the knob (3) compressing a spring in the recessed position. The knob slides on a shaft (1). The knob is locked in the recessed or the projecting position by a tongue at the end of a locking bar (22). The tongue runs in a guide formed in the knob. When the knob is depressed in the recessed position the guide carries the tongue clear so the spring can pop the knob out. The guide re-engages the tongue when the knob is then pressed inward. USE/ADVANTAGE Simple and compact mechanism for retractable control knobs, used for example to control heating and air conditioning in motor vehicles.

Description

BOUTON ESCAMOTABLE DE COMMANDE D'UN ARBRE
SUPPORT TOURNANT
L'invention concerne un bouton escamotable destiné à la commande d'un arbre support tournant et concerne plus particulièrement un bouton de commande d'une installation de chauffage et de climatisation de véhicule automobile disposé sur un tableau de bord.RETRACTABLE SHAFT CONTROL BUTTON
ROTATING SUPPORT
The invention relates to a retractable button for controlling a rotating support shaft and more particularly relates to a button for controlling a heating and air conditioning installation of a motor vehicle arranged on a dashboard.

La publication FR-A-2447060 décrit un bouton escamotable dont le corps du bouton est, en appui sur un,ressort de poussée. Un système de positionnement du bouton est constitué par une rainure de guidage associée à un contour qui contient une saillie d'arrêt d'une bille qui assure le verrouillage axial du corps du bouton par rapport à son support.The publication FR-A-2447060 describes a retractable button, the body of the button, being supported on a, push spring. A button positioning system is constituted by a guide groove associated with a contour which contains a stop projection of a ball which ensures the axial locking of the button body relative to its support.

Lorsque les dimensions de ce support sont réduites aux dimensions de l'arbre, le dispositif de verrouillage axial du bouton ne peut plus être assuré de manière simple.When the dimensions of this support are reduced to the dimensions of the shaft, the axial locking device of the button can no longer be provided in a simple manner.

La présente invention a pour objet de remédier à cet inconvénient et permet de réaliser un bouton escamotable destiné à la commande d'un arbre rotatif associé à un organe de traction.The object of the present invention is to remedy this drawback and makes it possible to produce a retractable button intended for controlling a rotary shaft associated with a traction member.

L'invention a également pour objet un bouton de commande qui possède une position stable escamotée et qui peut être extrait de son logement.The invention also relates to a control button which has a stable retracted position and which can be removed from its housing.

L'invention a encore pour objet un bouton de commande dont les manoeuvres destinées à obtenir son rangement dans une position escamotée et sa mise en service dans une position axialement différente sont réalisées de manière particulièrement simple.The invention also relates to a control button, the maneuvers for obtaining its storage in a retracted position and its commissioning in an axially different position are carried out in a particularly simple manner.

Selon l'invention - le moyen de verrouillage du bouton est porté par une tige articulée sur
un plateau d'appui du ressort de poussée du bouton, - une saillie d'arrêt dudit moyen de verrouillage possède une rampe de
commande de déflexion de ladite tige orientée vers le bord du contour
associé à la rainure de guidage du moyen de verrouillage. According to the invention - the button locking means is carried by a rod articulated on
a support plate for the pushing spring of the button, - a stop projection of said locking means has a ramp of
deflection control of said rod oriented towards the edge of the contour
associated with the guide groove of the locking means.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture d'un exemple de réalisation du bouton de commande en référence au dessin annexé dans lequel: - la figure 1 représente une partie du tableau de bord portant les boutons
de commande d'une installation de chauffage et de ventilation, - la figure 2 est une vue en coupe longitudinale d'un bouton de
commande représenté à la figure 1, - la figure 3 est une vue en coupe longitudinale axiale du bouton de

de la figure 2, - la figure 5 est une vue en coupe longitudinale du bouton de commande
représenté dans sa position de mise en service, - la figure 6 est une représentation partielle agrandie du détail A
représenté à la figure 5, - la figure 7 est une vue en plan de la cinématique de commande du câble
de transmission à partir d'un bouton conforme à l'invention.Other characteristics and advantages of the invention will appear on reading an exemplary embodiment of the control button with reference to the appended drawing in which: - Figure 1 shows a part of the dashboard carrying the buttons
control of a heating and ventilation installation, - Figure 2 is a longitudinal sectional view of a button
control shown in Figure 1, - Figure 3 is an axial longitudinal sectional view of the button
control along line mm in FIG. 2, FIG. 4 is a sectional view of the axis of the button along line IV-IV
of Figure 2, - Figure 5 is a longitudinal sectional view of the control button
shown in its operating position, - Figure 6 is an enlarged partial representation of detail A
shown in Figure 5, - Figure 7 is a plan view of the cable control kinematics
transmission from a button according to the invention.

Ainsi que cela a été représenté à la figure 1, le tableau de bord défini par sa façade 1 possède des alvéoles 2 de réception, du bouton 3 destiné à régler le débit d'un moto-ventilateur, du bouton 4 destiné à régler l'ouverture et la fermeture des orifices de distribution d'air, du bouton 5 destiné à commander un répartiteur d'air. Ainsi que cela est bien connu, les orifices de distribution de l'air sont commandés par des volets qui permettent par exemple de mélanger ou de séparer l'air de chauffage et l'air de ventilation et sa distribution dans l'habitacle.As shown in Figure 1, the dashboard defined by its facade 1 has cells 2 for receiving, button 3 intended to regulate the flow of a motor-ventilator, button 4 intended to regulate the opening and closing of the air distribution orifices, of the button 5 intended to control an air distributor. As is well known, the air distribution orifices are controlled by flaps which make it possible, for example, to mix or separate the heating air and the ventilation air and its distribution in the passenger compartment.

Ainsi que cela est montré à la figure 7, le volet est manoeuvré par un câble de transmission 8 ancré sur un secteur denté 9 actionné par un pignon 10 monté sur l'arbre support 11 du bouton. Une platine 12 en matériau isolant, porte des pistes conductrices 13 sur lesquelles prennent appui des contacts électriques 14 portés par un plateau 15 solidaire de l'arbre 11.As shown in Figure 7, the shutter is operated by a transmission cable 8 anchored on a toothed sector 9 actuated by a pinion 10 mounted on the support shaft 11 of the button. A plate 12 made of insulating material, carries conductive tracks 13 on which are supported electrical contacts 14 carried by a plate 15 secured to the shaft 11.

L'arbre Il supporte le corps 16 d'un bouton tel que 3 et possède une section rainurée représentée à la figure 4. L'arbre il est monté dans le perçage axial du corps 16 muni à cet effet de nervures d'entraînement en rotation et lesdites rainures et nervures permettent le coulissement axial du corps 16 sur l'arbre 11 sous l'effet de poussées axiales communiquées par un ressort 18.The shaft It supports the body 16 of a button such as 3 and has a grooved section shown in Figure 4. The shaft it is mounted in the axial bore of the body 16 provided for this purpose with rotational drive ribs and said grooves and ribs allow the axial sliding of the body 16 on the shaft 11 under the effect of axial thrusts communicated by a spring 18.

Le ressort 18 prend à cet effet appui sur le plateau 15 et sur la base du corps 16 dans le but d'exercer une force de poussée sur l'ensemble constitué par le corps 16 et par le bouton 3 et d'assurer la position de mise en service du bouton telle que représentée à la figure 5.The spring 18 for this purpose bears on the plate 15 and on the base of the body 16 in order to exert a pushing force on the assembly formed by the body 16 and by the button 3 and to ensure the position of commissioning of the button as shown in Figure 5.

Le passage du bouton de la position escamotée telle que représentée à la figure 2 ou 3 à la position de service telle que représentée à la figure 5 nécessite la mise en oeuvre d'un système de verrouillage représenté plus en détail à la figure 6.The passage of the button from the retracted position as shown in FIG. 2 or 3 to the service position as shown in FIG. 5 requires the use of a locking system shown in more detail in FIG. 6.

Le système de verrouillage est essentiellement constitué par une rainure 20 qui assure le guidage d'un ergot de verrouillage 21 porté par une tige 22 articulée sur le plateau 15 d'appui du ressort 18.The locking system essentially consists of a groove 20 which guides a locking lug 21 carried by a rod 22 articulated on the support plate 15 of the spring 18.

La rainure 20 est portée par une nervure longitudinale du corps 16 et est associée à un contour de guidage 25 qui contient une saillie d'arrêt 26 de l'ergot 21. La saillie 26 possède une rampe 27 orientée vers le bord du contour 25 et destinée à la commande de déflexion de la tige 22.The groove 20 is carried by a longitudinal rib of the body 16 and is associated with a guide contour 25 which contains a stop projection 26 of the lug 21. The projection 26 has a ramp 27 oriented towards the edge of the contour 25 and intended for the control of deflection of the rod 22.

Selon une autre caractéristique du système de verrouillage, le contour de guidage 25 débouche dans deux mortaises 30, 31 séparées par une saillie 32 à rampe d'orientation 33.According to another characteristic of the locking system, the guide contour 25 opens into two mortises 30, 31 separated by a projection 32 with an orientation ramp 33.

La rampe 33 de la saillie 32 assure le guidage de l'ergot 21 de la saillie d'arrêt 26 vers la mortaise 31 sous l'action du ressort de poussée 18.The ramp 33 of the projection 32 guides the lug 21 of the stop projection 26 towards the mortise 31 under the action of the thrust spring 18.

Le fonctionnement du bouton est décrit ci-après en référence à la figure 6. The operation of the button is described below with reference to FIG. 6.

Dans la position escamotée du bouton représentée à la figure 2, l'ergot 21 est en appui sur la saillie d'arrêt 26 sous l'action du ressort de poussée 18.In the retracted position of the button shown in FIG. 2, the lug 21 is in contact with the stop projection 26 under the action of the thrust spring 18.

Lors d'une poussée sur le bouton, la rampe 33 entre en contact avec l'ergot 21 séparé de la saillie 26. L'ergot est alors guidé par la rampe 33 vers la mortaise 31.When the button is pushed, the ramp 33 comes into contact with the lug 21 separated from the projection 26. The lug is then guided by the ramp 33 towards the mortise 31.

Lorsque la poussée sur le bouton cesse, le ressort 18 assure le déplacement axial du corps de bouton 16 et son guidage le long de l'arbre 11.When the pushing on the button ceases, the spring 18 ensures the axial displacement of the button body 16 and its guidance along the shaft 11.

Durant ce déplacement l'ergot 21 est guidé dans la rainure 20 vers une position d'arrêt E marquée sur la figure.During this movement, the lug 21 is guided in the groove 20 towards a stop position E marked in the figure.

Le bouton occupe alors la position représentée à la figure 5 et permet la commande de rotation de l'arbre 11 et du pignon 10. The button then occupies the position shown in FIG. 5 and allows the control of rotation of the shaft 11 and of the pinion 10.

Lors d'une nouvelle poussée sur le bouton, le ressort 18 est comprimé entre le corps 16 du bouton et le plateau 15. L'ergot 21 est alors guidé le long de la rainure 20 vers la mortaise 30. Lorsque la poussée sur le bouton cesse, le ressort 18 se détend en déplaçant axialement le corps 16 jusqu'à ce que l'ergot 21 vienne en appui sur la saillie d'arrêt 26. Dans cette position le bouton reste en position escamotée.During a new push on the button, the spring 18 is compressed between the body 16 of the button and the plate 15. The lug 21 is then guided along the groove 20 towards the mortise 30. When the push on the button stops, the spring 18 expands by moving the body 16 axially until the lug 21 comes to bear on the stop projection 26. In this position the button remains in the retracted position.

Sans sortir du cadre de l'invention il est possible d'associer au déplacement axial du bouton un interrupteur destiné à allumer une lampe d'éclairage des divers symboles portés par la façade 1 du tableau de bord et d'un repère porté par le bouton. Without departing from the scope of the invention, it is possible to associate the axial displacement of the button with a switch intended to light a lighting lamp of the various symbols carried by the front panel 1 of the dashboard and of a mark carried by the button .
