Abstract
Description
L'invention a pour objet un interrupteur à bouton-poussoir comprenant un bâti dont la face frontale présente une découpe rectangulaire dans laquelle est monté un bouton-poussoir rectangulaire agissant directement ou indirectement sur au moins une paire de contacts, ce bouton-poussoir étant muni, sur une partie au moins de son pourtour, d'un talon par lequel il est retenu dans le bâti, contre l'action d'un moyen élastique, de telle sorte que le bouton-poussoir peut être déplacé parallèlement au plan de la découpe pour être fixé, par un cran, dans une position actionnée.The subject of the invention is a push-button switch comprising a frame the front face of which has a rectangular cutout in which is mounted a rectangular push-button acting directly or indirectly on at least one pair of contacts, this push-button being provided , on at least part of its periphery, of a heel by which it is retained in the frame, against the action of an elastic means, so that the push-button can be moved parallel to the plane of the cutout to be fixed, by a notch, in an actuated position.
On connaît un interrupteur de ce type, commercialisé sous la marque "dh", dans lequel le bouton-poussoir agit sur une pièce métallique en forme de bascule dont l'une des extrémités agit directement sur deux contacts et dont l'autre extrémité est soumise à l'action d'un ressort qui a simultanément pour effet de ramener le bouton-poussoir en position non actionnée. Le cran du bouton-poussoir est constitué par une portée qui vient s'engager sous l'un des bords de la découpe du bâti lorsqu'on presse obliquement sur le bouton-poussoir. Un tel interrupteur a l'avantage de pouvoir fonctionner, soit comme un interrupteur à une seule position stable, soit comme un interrupteur à deux positions stables. Lorsque le bouton-poussoir est fixé en position actionnée par son cran, il est nécessaire, pour le libérer, de le tirer dans la direction opposée à son cran.A switch of this type is known, marketed under the brand "dh", in which the push button acts on a metal part in the form of a rocker, one end of which acts directly on two contacts and the other end of which is subjected to the action of a spring which simultaneously has the effect of returning the push button to the non-actuated position. The notch of the push button is constituted by a bearing which engages under one of the edges of the cutout of the frame when the button is pressed obliquely. Such a switch has the advantage of being able to function either as a switch with a single stable position or as a switch with two stable positions. When the push button is fixed in the position actuated by its notch, it is necessary, to release it, to pull it in the direction opposite to its notch.
La présente invention a pour but d'obtenir le retour du bouton-poussoir dans sa position de repos, non actionnée, par une simple pression sur le bouton-poussoir, et ceci avec un minimum de pièces.The object of the present invention is to obtain the return of the push-button to its rest position, not actuated, by a simple pressure on the push-button, and this with a minimum of parts.
L'interrupteur selon l'invention est caractérisé en ce que le bouton-poussoir est venu d'une pièce avec une patte de fixation à laquelle l'un des côtés du bouton-poussoir est relié par au moins une partie souple et élastiquement extensible, le côté opposé du bouton-poussoir étant pourvu d'un profil d'accrochage formé sur l'avers du bouton-poussoir et destiné à venir s'accrocher sous le bord correspondant de la découpe lorsque le bouton-poussoir est enfoncé obliquement en direction de son profil d'accrochage.The switch according to the invention is characterized in that the push button has come in one piece with a fixing tab to which one of the sides of the push button is connected by at least one flexible and elastically extensible part, the opposite side of the push button being provided with a hooking profile formed on the obverse of the push button and intended to come to hang under the corresponding edge of the cutout when the push button is pressed obliquely in the direction of its attachment profile.
La partie souple reliant le bouton-poussoir à sa patte de fixation est de préférence constituée d'un pli de matière amincie qui assure simultanément l'articulation du bouton-poussoir et son retrait en position de repos lorsque le bouton-poussoir est décroché par une simple pression.The flexible part connecting the push button to its fixing lug preferably consists of a fold of thinned material which simultaneously ensures the articulation of the push button and its withdrawal in the rest position when the push button is released by a one touch.
Le bouton-poussoir peut, soit actionner un interrupteur, soit court-circuiter directement deux bornes de contact au moyen d'une plaquette métallique fixée à l'extrémité d'un bras flexible venu d'une pièce avec le bouton-poussoir.The push-button can either activate a switch or directly short-circuit two contact terminals by means of a metal plate fixed to the end of a flexible arm joined in one piece with the push-button.
Une forme d'exécution est représentée, à titre d'exemple, dans le dessin annexé.
- La figure 1 est une vue en plan de l'interrupteur.
- La figure 2 est une vue en coupe selon II-II de la figure 1 en position non activée de l'interrupteur.

- Figure 1 is a plan view of the switch.
- Figure 2 is a sectional view along II-II of Figure 1 in the non-activated position of the switch.
- Figure 3 is a view similar to that of Figure 2 showing the activated switch and the push button evening locked in this position.
L'interrupteur représenté aux figures 1 et 2 comprend une plaque-support 1 sur laquelle est fixé un interrupteur 2 actionnable par pression sur un plot 3. Un tel interrupteur est bien connu en soi. Il peut être bipolaire ou multipolaire. Sur la plaque-support 1 est fixé un capot rectangulaire 4 présentant une découpe rectangulaire 5, mieux visible à la figure 3. Dans cette découpe 5 est disposé un bouton-poussoir rectangulaire 6 muni d'une jupe 7 se terminant par un talon périphérique 8 par lequel le bouton-poussoir 6 est retenu contre la face interne du capot 4. Le bouton-poussoir 6 est fixé sur un téton 9 prévu sur la face interne du capot 4 par une patte de fixation 10 à laquelle le bouton-poussoir est relié par un pli de matière amincie 11 donnant à la liaison une flexibilité permettant au bouton-poussoir 6 de basculer en direction de l'interrupteur 2 et présentant en outre une élasticité dans une direction parallèle à la face du capot 4. Le bouton-poussoir 6 est en outre muni d'un bras oblique flexible 12 s'appuyant sur le plot 3 de l'interrupteur 2. Le côté du bouton-poussoir 6 opposé à son point de fixation au capot présente un profil d'accrochage formé par une nervure de faible hauteur 13 le long du bord du bouton-poussoir. La face du bouton-poussoir 6 présente en outre une seconde nervure 14 plus haute que la nervure 13. Les deux nervures 13 et 14 définissent entre-elles un cran 15. Le bord correspondant de la découpe 5 présente un bourrelet 16 dirigé vers l'intérieur et destiné à coopérer avec le cran 15. Le bouton-poussoir, avec son bras et sa patte de fixation 10 peut être aisément réalisé en matière synthétique, par injection.The switch shown in Figures 1 and 2 comprises a support plate 1 on which is fixed a
Si on appuie sur le bouton-poussoir 6 perpendiculaire ment, selon la direction de la flèche F1 ou approximativement selon cette direction, le bouton-poussoir 6 bascule autour de son articulation 11 et le bras 12, présentant une rigidité suffisante à cet effet, vient actionner l'interrupteur 2, en fléchissant légèrement lorsqu'on relâche la pression sur le bouton-poussoir 6, celui-ci est ramené dans sa position initiale, représentée à la figure 2, par l'élasticité de l'interrupteur et celle du bras 12.If you press the
Si par contre on exerce une pression sur le bouton-poussoir en poussant simultanément la nervure 14 en direction du bord correspondant de la découpe 5, ce qui peut se traduire par une force résultante oblique F2 (figure 3), la nervure 13 passe derrière le bourrelet 16 du capot et vient s'accrocher sur ce bourrelet lorsqu'on relâche le bouton-poussoir. La nervure 14 a également pour effet de limiter le déplacement transversal du bouton-poussoir en venant buter contre le bord de la découpe 5. Cette position est représentée à la figure 3. L'interrupteur 2 est maintenu en position actionnée et l'ensemble fonctionne comme un interrupteur à deux positions stables. Pour libérer le bouton-poussoir 6, il suffit d'exercer une pression approximativement perpendiculaire sur celui-ci, le bouton-poussoir étant ramené en face de la découpe 5 grâce à l'élasticité de la liaison 11 qui agit comme un ressort de rappel.If, on the other hand, pressure is exerted on the push-button by simultaneously pushing the
De nombreuses variantes sont possibles sans sortir du cadre de l'invention. En particulier, le profil d'accrochage pourrait être réalisé de façon différente, par exemple par des surfaces dentelées ou rugueuses. La liaison 11 pourrait présenter plusieurs plis ou ondulations. Elle pourrait également être réalisée sans pli ni ondulation en utilisant un matériau présentant une certaine élasticité à la traction dans sa partie amincie. La liaison 11 pourait être subdivisée en plusieurs bandes. Au lieu d'actionner un interrupteur, comme représenté, le bras flexible 12 pourrait être muni d'une partie métallique pour assurer directement un court-circuit entre deux bornes. L'interrupteur pourrait bien entendu travailler en coupe-circuit. Le bouton-poussoir 6 pourrait présenter plusieurs bras d'actionnement 12.Many variations are possible without departing from the scope of the invention. In particular, the attachment profile could be produced in a different way, for example by serrated or rough surfaces. The
Dans le cas, représenté, où le bras 12 du bouton-poussoir actionne un interrupteur, ce bras pourrait être rigide, voire supprimé, l'élasticité étant assurée par l'interrupteur lui-même.In the case shown, where the
