Description

La présente invention concerne un bouton-poussoir à impulsion du type comportant un poussoir tubulaire logé coaxialement dans un corps cylindrique pour agir sur des contacts électriques, guidé en translation dans le corps et sollicité par un ressort de rappel. Un tel bouton-poussoir est décrit par exemple dans EP-A-0 721 196.The present invention relates to an impulse push button of the type comprising a tubular plunger housed coaxially in a cylindrical body to act on electrical contacts, guided in translation in the body and biased by a return spring. Such a push button is described for example in EP-A-0 721 196.

De tels boutons-poussoir à impulsion, aussi appelés boutons à simple poussée, sont bien connus. L'utilisateur presse un doigt sur le poussoir qui descend et commute les contacts électriques ; quand l'utilisateur relâche sa pression sur le poussoir, celui-ci remonte sous l'effet du ressort de rappel, alors que les contacts électriques reviennent à leur état initial, et il reprend sa position initiale.Such impulse push buttons, also called single push buttons, are well known. User presses finger on descending pusher and switches the electrical contacts; when the user releases his pressure on the pusher, it rises under the effect of the return spring, as the electrical contacts return to their initial state, and it resumes its initial position.

Il est désavantageux de ne pouvoir obtenir de manière simple dans les boutons-poussoir connus à impulsion et à action dépendante un retour sonore et tactile significatif du bon actionnement des contacts. Il est d'autre part connu de réaliser des boutons-poussoir à rupture brusque dans lesquels on obtient un effet de commutation brusque par exemple par dépassement du point mort de ressorts ; dans ces boutons-poussoir à rupture brusque, la commutation s'accompagne d'un effet sonore et tactile, mais suppose bien sûr la présence d'un mécanisme de rupture brusque.It is disadvantageous not to be able to obtain in a simple way in the known push buttons with dependent action sound feedback and significant touch of good contact actuation. There is other known part of making snap-action push buttons in which an abrupt switching effect is obtained, for example by overshooting springs dead center; in these snap buttons abrupt, switching is accompanied by a sound and tactile effect, but of course assumes the presence of an abrupt rupture mechanism.

Dans les boutons-poussoir à accrochage, aussi appelés boutons "pousser-pousser" ou à double poussée, il est connu d'utiliser une came à zone d'accrochage, par exemple en forme de coeur, et un ressort en épingle pour obtenir, à la fin du mouvement de descente du poussoir, la retenue de l'épingle dans la zone d'accrochage de la came empêche la remontée du poussoir ; lors de l'actionnement suivant du poussoir, l'épingle se dégage de la zone d'accrochage lors du mouvement de descente du poussoir et celui-ci peut remonter librement. Mais un tel mécanisme est dédié à un accrochage spécifique du type de bouton considéré.In snap-on push buttons, also called push-push buttons or double thrust, it is known to use a cam with an attachment zone, for example in the shape of a heart, and a pin spring for obtain, at the end of the downward movement of the pusher, the retention of the pin in the cam attachment area prevents the ascent of the pusher; during the next actuation of the pusher, the pin is released from the attachment zone during the downward movement of the pusher and the latter can go up freely. But such a mechanism is dedicated to hanging specific to the type of button considered.

L'invention a pour but de réaliser un retour sonore et tactile vers l'utilisateur d'un bouton-poussoir à simple poussée à action dépendante, c'est-à-dire sans rupture brusque, ce retour étant significatif du bon fonctionnement du bouton-poussoir et étant obtenu par des moyens simples.The object of the invention is to provide sound and tactile feedback to the user of a single push button with dependent action, i.e. without sudden break, this return being significant of the good functioning of the push button and being obtained by simple means.

Selon l'invention, le poussoir présente une paroi dotée d'une came coopérant avec une partie active, par exemple terminale, d'un ressort en forme d'épingle, cette épingle étant par ailleurs encastrée dans le corps et emmagasinant de l'énergie en fonction de sa sollicitation par la came ; d'autre part, la came a un profil doté d'au moins un point de rebroussement, ce profil étant parcouru, entièrement et sans accrochage de maintien, par la partie active de l'épingle, à la suite d'un cycle d'actionnement du poussoir, c'est-à-dire d'un mouvement de descente et de remontée du poussoir ; enfin, la paroi du poussoir présente un ressaut associé au point de rebroussement pour permettre un saut de la partie active de l'épingle.According to the invention, the pusher has a wall provided with a cooperating cam with an active part, for example a terminal part, of a shaped spring pin, this pin being also embedded in the body and storing energy as a function of its stress on the cam; else hand, the cam has a profile provided with at least one cusp, this profile being traversed, entirely and without holding hook, by the part active pin, following an actuation cycle of the pusher, that is to say a movement of descent and ascent of the pusher; finally, the wall of the pusher has a projection associated with the cusp point for allow a jump of the active part of the pin.

On obtient ainsi de manière très simple par la présence d'une came en boucle et d'un ressaut associé la sensation sonore et tactile recherchée. We thus obtain very simply by the presence of a looped cam and an associated jump the desired sound and tactile sensation.

De préférence, la partie terminale de l'épingle est un coude dont l'extrémité radiale est apte à percuter le fond du ressaut au franchissement de celui-ci par le coude.Preferably, the terminal part of the pin is an elbow whose end radial is able to strike the bottom of the projection when crossing it by the elbow.

La description va être faite ci-après d'un mode de réalisation de l'invention, à titre non limitatif et en regard des dessins annexés.The description will be made below of an embodiment of the invention, without limitation and with reference to the accompanying drawings.

La figure 1 représente en coupe axiale un bouton-poussoir conforme à l'invention.Figure 1 shows in axial section a push button according to the invention.

La figure 2 est une vue agrandie du détail A de la figure 1.FIG. 2 is an enlarged view of detail A of FIG. 1.

La figure 3 est la vue selon B du détail de la figure 2.FIG. 3 is the view along B of the detail in FIG. 2.

La figure 4 montre en perspective la came du bouton-poussoir.Figure 4 shows in perspective the cam of the push button.

Les figures 5A à 5E montrent les phases du mouvement relatif de la came et de l'aiguille lors d'un cycle d'actionnement du bouton-poussoir.FIGS. 5A to 5E show the phases of the relative movement of the cam and of the needle during a push button actuation cycle.

La figure 6 montre une variante de réalisation de la came.Figure 6 shows an alternative embodiment of the cam.

Le bouton-poussoir à impulsion représenté sur la figure 1 comprend un corps tubulaire 10 de forme générale cylindrique d'axe X, muni d'une tête 11 épanouie par rapport à un fût 12. Dans le corps 10 est disposé coaxialement un poussoir 20 de forme générale cylindrique, composé d'une partie haute 20a épanouie pour être logée dans la tête 11 et d'une partie basse 20b solidaire de la partie 20a et mobile dans le fût 12 ; le poussoir est mobile dans le corps 10 de manière à se déplacer en translation selon X en réponse à une pression exercée sur sa partie haute 20a, à l'encontre de l'effort d'un ressort de rappel hélicoïdal coaxial 21, tout en étant immobilisé en rotation autour de X. Le poussoir est arrêté en position haute dans le corps par des moyens de butée non représentés. Le terme cylindrique doit être compris au sens large et désigne également des formes prismatiques ou analogues.The impulse push button shown in Figure 1 includes a tubular body 10 of generally cylindrical shape with axis X, provided with a head 11 opened out with respect to a barrel 12. In the body 10 is arranged coaxially a generally cylindrical pusher 20, composed of an upper part 20a open to be housed in the head 11 and a bottom part 20b secured of the part 20a and movable in the barrel 12; the pusher is movable in the body 10 so as to move in translation along X in response to a pressure exerted on its upper part 20a, against the effort of a coaxial helical return spring 21, while being immobilized in rotation around X. The pusher is stopped in the high position in the body by stop means not shown. The term cylindrical must be understood in broad sense and also designates prismatic or similar forms.

Le guidage et le maintien en rotation du poussoir s'effectuent au moyen de formes appropriées, par exemple comme indiqué en 13 et 22. Le poussoir 20 est rattaché de façon étanche au corps par un joint 14 et forme à l'intérieur une chambre 23 qui peut loger un voyant.The pusher is guided and kept in rotation by means of suitable shapes, for example as indicated in 13 and 22. The pusher 20 is tightly attached to the body by a seal 14 and forms inside a room 23 which can accommodate a sight glass.

Le poussoir 20 présente sur son pourtour cylindrique une paroi 24 et, sur la face extérieure 25 de cette paroi, une came 30 qui coopère avec une partie active 16, de préférence une partie terminale coudée radialement vers l'axe X, d'un ressort 15 en forme d'épingle ou analogue ; l'extrémité 16a située vers l'axe X de la partie terminale 16 est appliquée contre la face 25. L'autre partie terminale 17 de l'épingle 15 est encastrée dans un logement 18 de l'extrémité inférieure du corps 10.The pusher 20 has on its cylindrical periphery a wall 24 and, on the outer face 25 of this wall, a cam 30 which cooperates with a part active 16, preferably a terminal portion bent radially towards the axis X, of a pin-shaped spring or the like; the end 16a located towards the X axis of the terminal part 16 is applied against the face 25. The other end part 17 of the pin 15 is embedded in a housing 18 of the lower end of the body 10.

Il convient de remarquer que l'épingle 15 s'étend dans une direction X1 parallèle à X, le long de la paroi cylindrique du fût 12 et de préférence dans une rainure ou une fente 19 de celui-ci. Comme on le verra plus loin, l'épingle 15 est assujettie à la came de manière à accumuler par flexion une énergie permettant d'obtenir l'effet tactile et sonore recherché, en combinaison avec un effet de percussion dû à l'échappement de son extrémité sur des formes adaptées de la face 25.It should be noted that the pin 15 extends in a direction X1 parallel at X, along the cylindrical wall of the barrel 12 and preferably in a groove or slot 19 thereof. As we will see later, the pin 15 is secured to the cam so as to accumulate by bending a energy to obtain the desired tactile and sound effect, in combination with a percussion effect due to the escape of its end on adapted shapes of the face 25.

La came 30 a sensiblement la forme d'un parallélogramme présentant deux côtés 32,34 essentiellement parallèles à l'axe X du corps et deux autres côtés obliques 31,33. Le côté oblique 33 situé vers la tête 11 du bouton-poussoir a une forme plate ou convexe sans discontinuité et le côté oblique 31 de la came situé à l'opposé de la tête peut aussi avoir une forme continue (voir figures 5A-5E) ou peut offrir une discontinuité ménageant une résistance tactile (voir figure 6). La came offre un point de rebroussement 35 (angle aigu du parallélogramme) à la transition entre les côtés 32,33 et un autre point de rebroussement 36 à la transition entre les côtés 34 et 31.The cam 30 has substantially the shape of a parallelogram having two sides 32,34 essentially parallel to the X axis of the body and two other sides obliques 31,33. The oblique side 33 located towards the head 11 of the push button has a flat or convex shape without discontinuity and the oblique side 31 of the cam located opposite the head can also have a continuous shape (see Figures 5A-5E) or may offer a discontinuity providing resistance touch (see Figure 6). Cam offers a cusp 35 (acute angle of the parallelogram) at the transition between the sides 32.33 and a another cusp 36 at the transition between sides 34 and 31.

D'autre part, la face extérieure 25 de la paroi 24 comprend une rampe légèrement montante 26a pour guider l'extrémité 16a du coude 16 de l'épingle 15 le long du côté 31 et une cuvette ou un retrait analogue 26b adjacent à la rampe 26a pour ménager un ressaut 27 au voisinage du point de rebroussement 35 ; de même; il est prévu une rampe légèrement montante 28a pour guider l'extrémité 16a du coude 16 le long du côté 34 et un retrait 28b adjacent à la rampe 28a pour ménager un ressaut 29 proche du point de rebroussement 36.On the other hand, the outer face 25 of the wall 24 comprises a ramp slightly rising 26a to guide the end 16a of the elbow 16 of the pin 15 along side 31 and a bowl or similar recess 26b adjacent to the ramp 26a to provide a projection 27 in the vicinity of the cusp 35; likewise; a slightly rising ramp 28a is provided for guide the end 16a of the elbow 16 along the side 34 and an adjacent recess 28b to the ramp 28a to provide a projection 29 close to the cusp 36.

Le bouton-poussoir décrit fonctionne de la manière suivante.The push button described operates as follows.

La position initiale est illustrée sur les figures 1 et 5A ; dans cette position, le poussoir 20 est appliqué en butée contre un élément du corps, tandis que la face supérieure du coude 16 est située au voisinage immédiat du côté inférieur 31 de la came 30, ou est appliquée sur ce côté, l'épingle étant au repos.The initial position is illustrated in Figures 1 and 5A; in this position, the pusher 20 is applied in abutment against an element of the body, while the upper face of the elbow 16 is located in the immediate vicinity of the side lower 31 of cam 30, or is applied on this side, the pin being at rest.

Lorsqu'un utilisateur actionne le bouton-poussoir en appuyant par un doigt sur sa partie haute 20a, le poussoir 20 descend et avec lui la came 30 (figure 5B), de sorte que le côté 31 de la came refoule le coude 16 de l'épingle 15 vers la gauche ; celle-ci fléchit et reste fléchie tandis que le coude 16 glisse sur le côté 32 de la came, jusqu'au point de rebroussement 35 (voir figure 5C) ; au franchissement du ressaut 27 associé au point 35, l'extrémité 16a du coude 16 restitue l'énergie accumulée en percutant le fond du retrait 26b. L'utilisateur perçoit alors un son indicatif que l'actionnement voulu a été exécuté, en même temps que son doigt ressent une réaction transmise par la came et le poussoir. La chambre 23 intérieure au poussoir accentue l'effet sonore.When a user presses the push button with a finger on its upper part 20a, the pusher 20 descends and with it the cam 30 (Figure 5B), so that the side 31 of the cam pushes back the elbow 16 of pin 15 to the left; it flexes and stays flexed while the elbow 16 slides on the side 32 of the cam, up to the cusp 35 (see Figure 5C); on crossing the projection 27 associated with point 35, the end 16a of the elbow 16 restores the energy accumulated by striking the bottom of withdrawal 26b. The user then perceives an indicative sound that the actuation wanted was executed, at the same time as his finger feels a reaction transmitted by the cam and the pusher. Room 23 inside the pusher accentuates the sound effect.

En remontant, le poussoir provoque le fléchissement vers la droite de l'épingle (voir figure 5D) par suite du glissement du côté 33 de la came contre le coude 16. Enfin, l'extrémité 16a du coude 16 monte sur la rampe 28a et, lorsque le coude franchit le point de rebroussement 36 et le ressaut 29 associé (figure 5E), elle vient percuter la face 25 dans le retrait 28b, de sorte que l'utilisateur perçoit un son et une réaction tactile comme précédemment. Bien entendu, les points de rebroussement, les rampes et les ressauts peuvent être dimensionnés pour privilégier par exemple la première indication (ressaut 27). De même, on peut prévoir un seul ressaut.Going up, the pushbutton causes the rightward sagging of the pin (see Figure 5D) due to the sliding of the side 33 of the cam against the elbow 16. Finally, the end 16a of the elbow 16 rises on the ramp 28a and, when the elbow crosses the cusp 36 and the jump 29 associated (Figure 5E), it strikes the face 25 in the recess 28b, so that the user perceives a sound and a tactile reaction as before. Of course, cusps, ramps and jumps can be sized to favor for example the first indication (jump 27). Likewise, a single projection can be provided.

On a représenté sur la figure 6 une variante dans laquelle une discontinuité 37 est prévue dans le côté 31 de la came 30 pour marquer une résistance tactile au départ de l'actionnement. Les cames indiquées à titre d'exemple peuvent bien entendu prendre d'autres formes équivalentes.FIG. 6 shows a variant in which a discontinuity 37 is provided in the side 31 of the cam 30 to mark a resistance touch at the start of actuation. Cams shown as an example can of course take other equivalent forms.
