Abstract

The control for mounting on the dashboard of a car includes a sliding toothed rack (3) with a button (4) attached to it projecting through a slot in the front panel (2). Between this toothed rack, and a fixed rack (8) there are two toothed wheels (9) of which the spindles are attached to a bar. This bar has a peg (12) which holds the eyelet at the end of the inner core of a coaxial cable. The outer sleeve is fastened at the base of the control. The cable may be used to control the heater. The rack and pinion mechanism provides a reduction in the operating force needed to move the cable since the sliding button moves a greater distance than the cable itself.

Description

Dispositif de commande à distance à partir d'un tableau de bord, en particulier pour vehicule automobile.Remote control device from a dashboard, in particular for a motor vehicle.

L'invention se rapporte aux dispositifs de commande à distance destines a l'equipement d'un tableau de bord, en particulier de véhicule automobile, en vue d'actionner manuellement des organes de reglage divers par l'intermédiaire d'une transmission mécanique articulée ou flexible, tels que des dispositifs de réglage du moteur du véhicule, des organes de climatisation ou autres accessoires. The invention relates to remote control devices intended for equipping a dashboard, in particular for a motor vehicle, with a view to manually actuating various adjustment members by means of an articulated mechanical transmission. or flexible, such as vehicle engine controls, air conditioning, or other accessories.

Les impératifs de sécurité obligent d utiliser des dispositifs de commande à saillie restreinte ou masquée dans les habitacles des véhicules. On connaît déjà à cet effet des systèmes à levier complexe évitant une saillie variable du levier de manoeuvre par rapport au tableau dans toute sa course de commande. Ces dispositifs sont généralement encombrants, sensibles à l'usure de leurs nombreuses articulations et ils laissent cependant subsister une variation angulaire de position du bouton de manoeuvre dans sa course. Safety requirements make it necessary to use control devices with limited or concealed projection in the cockpits of vehicles. Already known for this purpose complex lever systems avoiding a variable projection of the operating lever relative to the table throughout its control stroke. These devices are generally bulky, sensitive to the wear and tear of their numerous joints and they nevertheless allow an angular variation in the position of the operating button to remain in its course.

On connaft aussi des systemes utilisant des organes de commande manuels monts coulissants dans des glissières sur le tableau et directement attelés à la transmission de commande.There are also systems using manual control members slidingly mounted in slides on the switchboard and directly coupled to the control transmission.

Ces solutions sont ouvertes à des risques de coincement et elles ne permettent pas d'envisager des commandes démultipliées. La présente invention a pour objet un dispositif de commande perfectionné satisfaisant à la fois du point de vue de l'encombrement, de la démultiplication de l'effort de commande, des efforts de frottement et de l'absence de risque de coincement.These solutions are open to the risk of jamming and they do not make it possible to envisage multiplied orders. The present invention relates to an improved control device satisfying both from the point of view of space, the reduction of the control force, friction forces and the absence of risk of jamming.

Essentiellement à cet effet, le dispositif de commande selon l'invention, comprenant au tableau un elément mobile relié par un organe de liaison à l'organe commandé a distance, et un organe a commande manuelle pour actionner ledit élé- ment, est caractérisé en ce que ledit élément mobile est pourvu d'au moins une roue dentée montée en prise entre une crémaillère fixe par rapport au tableau de bord et une crémaillère montée coulissante par rapport à ce dernier et qui est pourvue dudit organe à commande manuelle.  Essentially for this purpose, the control device according to the invention, comprising on the board a movable element connected by a connecting member to the remotely controlled member, and a manually controlled member for actuating said element, is characterized in that said movable member is provided with at least one toothed wheel engaged between a fixed rack relative to the dashboard and a rack mounted sliding relative to the latter and which is provided with said manually controlled member.

Une forme de réalisation d'un dispositif de commande distance selon l'invention estci-après décrite à titre d'exemple et en référence au dessin annexé, dans lequel
la fig. l est une vue de dessus du dispositif de commande assemblé, une partie du couvercle de mécanisme étant arrachée;
la fig. 2 est une vue de façade du dispositif de commande (suivant flèche II de la fig. l et tourne de 900);

IV-IV.An embodiment of a remote control device according to the invention is described below by way of example and with reference to the accompanying drawing, in which
fig. l is a top view of the assembled control device, part of the mechanism cover being torn off;
fig. 2 is a front view of the control device (according to arrow II in FIG. 1 and turns 900);
fig. 3 is a sectional view of FIG. l next

fig. 4 is a sectional view of FIG. l next
IV-IV.

Le dispositif représenté comprend un support l qui peut comme ici être partie du dos de la façade 2 du tableau de bord. Sur ce support l est montée coulissante parallèlement à la façade 2 une crémaillère 3 pourvue d'un bouton de manoeuvre 4 dont la tige 5 traverse une fente 6 de la façade 2. Cette crémaillère 3 est interposée entre le support l et un couvercle 7 du mécanisme. Entre ce couvercle et le support l est en outre interposée et fixée une crémaillère 8 dont la denture fait face a celle de la crémaillère mobile 3.Entre les dentures des deux crémaillères 3 et 8 sont montées en prise avec elles deux roues dentées 9 et 10 dont les axes de rotation sont montés tournant dans une barrette il. Cette barrette il présente un téton de liaison 12 traversant une fente 13 du couvercle et auquel est attaché l'oeillet d'extrémité d'un câble 14 faisant partie d'une transmission flexible de commande d'un organe du véhicule, tel qu'un volet de climatisation. La gaine 16 de cette transmission est ici fixée en 17 sur le couvercle 7 lui-même. On comprend aisément que la crémaillère 8 étant fixe, lorsque le bouton de manoeuvre 4 et donc la crémaillère 3 est déplacée dans la longueur de la fente 6 qui détermine sa course de commande possible, l'ensemble de la barrette 8 et des roues dentées 9 et 10 n'est déplacé en translation que de la demi-course du bouton 4. The device shown comprises a support l which can, as here, be part of the back of the front panel 2 of the dashboard. On this support l is slidably mounted parallel to the front 2 a rack 3 provided with an operating button 4 whose rod 5 passes through a slot 6 in the front 2. This rack 3 is interposed between the support l and a cover 7 of the mechanism. Between this cover and the support l is further interposed and fixed a rack 8 whose toothing faces that of the movable rack 3. Between the teeth of the two racks 3 and 8 are engaged with them two toothed wheels 9 and 10 whose axes of rotation are mounted rotating in a bar there. This bar has a connecting stud 12 passing through a slot 13 in the cover and to which is attached the end eyelet of a cable 14 forming part of a flexible control transmission of a member of the vehicle, such as a air conditioning shutter. The sheath 16 of this transmission is here fixed at 17 on the cover 7 itself. It is easy to understand that the rack 8 being fixed, when the operating button 4 and therefore the rack 3 is displaced in the length of the slot 6 which determines its possible control stroke, the assembly of the bar 8 and the toothed wheels 9 and 10 is only displaced in translation by the half-stroke of the button 4.

L'effort de commande de l'organe actionné distance se trouve ainsi réduit de moitié par rapport à ce qu'il serait avec une commande directe ce qui accroît l'aisance de manoeuvre pour l'utilisateur. Cette démultiplication apporte aussi une meilleure progressivité de manoeuvre et une plus grande précision possible le cas échéant dans le positionnement recherché de l'organe commandé. On notera que la coopération de translation de l'organe commandé avec des organes roulants que sont ici les roues dentées 9 et 10 prévient particulièrement tout risque de coincement d'une telle commande. Bien entendu de nombreuses variantes peuvent etre imaginées sans pour autant sortir du domaine de l'invention. En particulier, avec un certain guidage lâche de la crémaillère mobile 3 par rapport au support et/ou au couvercle on pourrait utiliser un élément mobile pourvu d'une seule roue dentée. The control effort of the remotely actuated member is thus reduced by half compared to what it would be with direct control, which increases the ease of operation for the user. This reduction also provides better progressiveness of maneuver and greater possible precision if necessary in the desired positioning of the controlled member. It will be noted that the translational cooperation of the controlled member with rolling members that are here the toothed wheels 9 and 10 particularly prevents any risk of jamming of such a control. Of course many variants can be imagined without departing from the scope of the invention. In particular, with a certain loose guide of the movable rack 3 relative to the support and / or to the cover, a movable element provided with a single toothed wheel could be used.
