BOUTON DE COMMANDE D'APPAREIL ELECTROMENAGER
La présente invention concerne un bouton de commande d'appareil électroménager monté rotatif autour d'un axe transversal à un élément de carrosserie de l'appareil et comprenant un organe de préhension solidaire d'un corps monté rotatif à travers un alésage pratiqué dans ledit élément de carrosserie, et un arbre de transmission du mouvement de rotation agencé entre ledit corps et un composant électrique fixé sur un châssis agencé dans la carrosserie de l'appareil. HOUSEHOLD APPLIANCE CONTROL BUTTON
The present invention relates to a household appliance control button mounted to rotate about an axis transverse to a body element of the device and comprising a gripping member secured to a body mounted to rotate through a bore formed in said element. bodywork, and a shaft for transmitting the rotational movement arranged between said body and an electrical component fixed to a chassis arranged in the bodywork of the apparatus.
Dans le domaine de l'électroménager, on cherche à réaliser des appareils de plus en plus compact pour réduire leur encombrement, et par conséquent la place disponible pour le panneau de commande qui regroupe les organes de commande est de plus en plus réduite. In the field of household appliances, it is sought to produce increasingly compact devices in order to reduce their bulk, and consequently the space available for the control panel which groups together the control members is more and more reduced.
Certains organes de commande sont formés par un élément de la carrosserie qui est monté flottant par rapport à la carrosserie et au châssis de l'appareil, c'est-à-dire un élément qui peut être enfoncé ou qui peut basculer autour d'un ou deux axes. Les dimensions de ces organes de commande, constitués par une partie mobile de la carrosserie, ne peuvent être réduites au-delà d'une certaine taille, soit parce qu'il est nécessaire d'exercer une force relativement importante sur cette partie mobile pour obtenir par exemple l'ouverture d'une porte d'un four, soit parce que l'organe de commande doit être facilement accessible comme dans le cas d'une pédale de commande d'aspirateur qui est actionnée avec le pied. Certain control members are formed by an element of the body which is mounted floating relative to the body and the chassis of the apparatus, that is to say an element which can be pushed in or which can tilt around a or two axes. The dimensions of these control members, constituted by a movable part of the body, cannot be reduced beyond a certain size, either because it is necessary to exert a relatively large force on this movable part to obtain for example the opening of a door of an oven, either because the control member must be easily accessible as in the case of a vacuum cleaner control pedal which is actuated with the foot.
Ces appareils comportent aussi des organes de commande constitués par des boutons rotatifs qui dans l'art antérieur doivent être montés sur une partie fixe de la carrosserie. Il est donc nécessaire de ménager un espace supplémentaire pour disposer sur le panneau de commande à These devices also include control members constituted by rotary knobs which in the prior art must be mounted on a fixed part of the body. It is therefore necessary to provide additional space to have on the control panel to
<Desc/Clms Page number 2><Desc / Clms Page number 2>
la fois des organes de commande constitués d'éléments de carrosserie montés flottants et des boutons rotatifs. both control elements made up of floating mounted bodywork elements and rotary knobs.
L'objet de la présente invention est de remédier à ces inconvénients, en réalisant un bouton de commande rotatif permettant d'obtenir un panneau de commande de dimensions réduites sans augmenter son coût de fabrication. The object of the present invention is to remedy these drawbacks, by producing a rotary control button making it possible to obtain a control panel of reduced dimensions without increasing its manufacturing cost.
Selon l'invention, l'élément de carrosserie étant monté flottant par rapport à la carrosserie et au châssis de l'appareil, l'arbre de transmission du bouton de commande comporte une partie flexible formée par une lame pré-vrillée. According to the invention, the bodywork element being mounted floating relative to the bodywork and to the chassis of the apparatus, the drive shaft of the control button comprises a flexible part formed by a pre-twisted blade.
Grâce à cette disposition, l'organe de préhension et le corps du bouton suivent les mouvements de l'élément de carrosserie flottant tout en étant aptes à transmettre le mouvement de rotation au composant électrique fixe. Il est alors possible de monter le bouton sur un organe de commande flottant de l'appareil, et ainsi, les dimensions du panneau de commande peuvent être réduites aux dimensions dudit organe de commande flottant. Thanks to this arrangement, the gripping member and the body of the button follow the movements of the floating body element while being able to transmit the rotational movement to the fixed electrical component. It is then possible to mount the button on a floating control member of the apparatus, and thus, the dimensions of the control panel can be reduced to the dimensions of said floating control member.
D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, donnée à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels : - la figure 1 est une vue en perspective d'une coupe verticale d'un aspirateur électroménager comportant un bouton de commande selon l'invention ; - la figure 2 est une vue agrandie en perspective du bouton de commande ; - la figure 3 est une vue agrandie en coupe suivant la ligne II-II de la figure 2. Other characteristics and advantages of the invention will emerge from the description which follows, given by way of nonlimiting example, with reference to the appended drawings in which: - Figure 1 is a perspective view of a vertical section d 'a household vacuum cleaner comprising a control button according to the invention; - Figure 2 is an enlarged perspective view of the control button; - Figure 3 is an enlarged sectional view along line II-II of Figure 2.

A la figure 1, on a représenté un aspirateur électroménager 1 en coupe verticale. Un bouton de commande 2 de l'aspirateur 1 est monté rotatif autour d'un axe A-A transversal à un élément de carrosserie 3 de l'appareil. Le bouton de commande 2 comprend un organe de préhension 4 solidaire d'un corps 5 monté rotatif à travers un alésage pratiqué dans ledit élément de carrosserie 3, et un arbre de transmission 6 du mouvement de rotation agencé entre ledit corps 5 et un composant électrique 7 fixé sur un châssis 8 de l'appareil agencé dans la carrosserie 9. Dans le mode de réalisation représenté, le composant électrique 7 est un potentiomètre rotatif permettant de moduler la puissance du groupe d'aspiration 11. In Figure 1, there is shown a household vacuum cleaner 1 in vertical section. A control button 2 of the vacuum cleaner 1 is rotatably mounted about an axis A-A transverse to a body element 3 of the device. The control button 2 comprises a gripping member 4 secured to a body 5 rotatably mounted through a bore formed in said body element 3, and a shaft 6 for transmitting the rotational movement arranged between said body 5 and an electrical component 7 fixed on a chassis 8 of the device arranged in the bodywork 9. In the embodiment shown, the electrical component 7 is a rotary potentiometer making it possible to modulate the power of the suction group 11.
Selon l'invention, l'élément de carrosserie 3 étant monté flottant par rapport à la carrosserie 9 et au châssis 8 de l'appareil, l'arbre de transmission 6 du bouton de commande 2 comporte une partie flexible 12 formée par une lame pré-vrillée. Grâce à cette partie flexible 12, l'arbre de transmission 6 peut transmettre le mouvement de rotation au composant électrique 7 quelle que soit la position du corps 5 du bouton qui suit les mouvements de l'élément de carrosserie 3 monté flottant. According to the invention, the bodywork element 3 being mounted floating relative to the bodywork 9 and to the chassis 8 of the apparatus, the transmission shaft 6 of the control button 2 comprises a flexible part 12 formed by a blade pre -vrillée. Thanks to this flexible part 12, the transmission shaft 6 can transmit the rotational movement to the electrical component 7 whatever the position of the body 5 of the button which follows the movements of the bodywork element 3 mounted floating.
Dans le mode de réalisation représenté, l'élément de carrosserie 3 comporte sur sa face intérieure une aile 13 munie de deux ouvertures ovoïdes à travers lesquelles passent deux axes, non visibles sur la figure 1, solidaires du châssis 8. Le centre de la partie avant 14 de l'élément 3 prend appui sur la partie fixe de la carrosserie, tandis qu'un espace est ménagé entre d'une part la carrosserie 9, et d'autre part, les côtés et la partie arrière 15 de l'élément 3. L'élément de carrosserie 3 est maintenu écarté du reste de la carrosserie à l'aide de ressorts 16 en une position In the embodiment shown, the body element 3 has on its inner face a wing 13 provided with two ovoid openings through which pass two axes, not visible in FIG. 1, integral with the chassis 8. The center of the part front 14 of the element 3 is supported on the fixed part of the body, while a space is provided between on the one hand the body 9, and on the other hand, the sides and the rear part 15 of the element 3. The bodywork element 3 is kept apart from the rest of the bodywork using springs 16 in one position.

appelée position de repos et il peut basculer autour de l'axe longitudinal de l'aspirateur 1, ainsi qu'autour d'un axe transversal. L'élément de carrosserie 3 forme alors une pédale de commande de l'aspirateur 1 dont le mouvement depuis la position de repos permet de commander la mise en marche et/ou l'enroulement d'un cordon d'alimentation. called the rest position and it can tilt around the longitudinal axis of the vacuum cleaner 1, as well as around a transverse axis. The bodywork element 3 then forms a pedal for controlling the vacuum cleaner 1 whose movement from the rest position makes it possible to control the starting and / or winding of a power cord.
Comme cela apparaît mieux aux figures 2 et 3, la section transversale d'une partie rigide 17 de l'arbre de transmission 6 est sensiblement un carré de côté a, tandis que la section transversale de la partie flexible 12 de l'arbre de transmission est'un rectangle de longueur L approximativement égale au côté a du carré et de largeur 1 nettement inférieure au côté a, l'orientation de ladite section transversale rectangulaire évoluant selon un mouvement hélicoïdal le long de la partie flexible de l'arbre de transmission. As is better seen in FIGS. 2 and 3, the cross section of a rigid part 17 of the transmission shaft 6 is substantially a square with side a, while the cross section of the flexible part 12 of the transmission shaft is a rectangle of length L approximately equal to the side a of the square and of width 1 much less than the side a, the orientation of said rectangular cross section evolving in a helical movement along the flexible part of the transmission shaft.
Ainsi, la partie flexible 12 peut être déformée dans des directions perpendiculaires à son axe principal, tout en pouvant transmettre un mouvement de rotation autour de cet axe principal. La partie rigide 17 de section carrée permet d'entraîner directement le composant électrique sans pièce intermédiaire. Thus, the flexible part 12 can be deformed in directions perpendicular to its main axis, while being able to transmit a rotational movement around this main axis. The rigid part 17 of square section makes it possible to drive the electrical component directly without any intermediate part.
De manière préférentielle, l'orientation de la section transversale rectangulaire évolue d'un quart de tour entre le début et la fin de la partie flexible 12 de l'arbre de transmission 6. Cette disposition permet d'obtenir une partie flexible courte et présentant une résistance à la déformation constante quelle que soit la direction de celle-ci. Preferably, the orientation of the rectangular cross section changes by a quarter of a turn between the start and the end of the flexible part 12 of the drive shaft 6. This arrangement makes it possible to obtain a short flexible part having a constant resistance to deformation whatever the direction thereof.
Le bouton de commande 2 comprenant une telle partie flexible peut très facilement être réalisé en une seule The control button 2 comprising such a flexible part can very easily be produced in a single
<Desc/Clms Page number 5><Desc / Clms Page number 5>
pièce de plastique moulée afin de minimiser les coûts de fabrication. molded plastic part to minimize manufacturing costs.
De manière préférentielle, le corps 5 du bouton de commande comporte une gorge circulaire 18 adaptée à coopérer avec un rebord 19 de l'alésage de l'élément de carrosserie 3 afin de bloquer tout mouvement de translation axiale du bouton 2. De plus, cela facilite le montage du bouton 2 qui peut être réalisé par simple enfoncement dans l'alésage. Preferably, the body 5 of the control button has a circular groove 18 adapted to cooperate with a flange 19 of the bore of the bodywork element 3 in order to block any movement of axial translation of the button 2. In addition, this facilitates the mounting of the button 2 which can be achieved by simply driving in the bore.
L'invention répond ainsi au souci d'obtenir un panneau de commande de dimensions réduites, car elle permet de monter un bouton de commande sur un élément de carrosserie flottant, ledit élément constituant lui-même un organe de commande. The invention thus responds to the concern of obtaining a control panel of reduced dimensions, because it makes it possible to mount a control button on a floating bodywork element, said element itself constituting a control member.
Le mode de réalisation décrit n'est nullement limitatif, l'invention peut être appliquée à d'autres types d'appareils électroménagers. Par exemple, il peut s'agir d'un four à micro-ondes dont un élément de carrosserie monté flottant permet de commander l'ouverture de la porte, ledit élément de carrosserie comportant des boutons rotatifs pour régler la puissance et la durée de cuisson. The embodiment described is in no way limiting, the invention can be applied to other types of household appliances. For example, it may be a microwave oven, a floating mounted body element used to control the opening of the door, said body element comprising rotary knobs for adjusting the power and the cooking time. .
