La présente invention concerne un élément d 'actionnement comprenant une pièce mince présentant une zone déformable dans le sens de son épaisseur de manière à occuper au moins deux positions dans au moins l'une desquelles cette zone est arquée.The present invention relates to an actuating element comprising a thin piece having a deformable zone in the direction of its thickness so as to occupy at least two positions in at least one of which this zone is arched.
Des éléments d 'actionnement constitués uniquement d'une pièce mince déformable de cette manière sont déjà connus. Cependant, la course obtenue par cette déformation, qui permet l'actionnement d'un organe à commander, est faible. Cette faible course entraîne des inconvénients notamment lorsque l'organe à actionner est un interrupteur.Actuating elements consisting only of a thin piece deformable in this way are already known. However, the stroke obtained by this deformation, which allows the actuation of a member to be controlled, is small. This short stroke causes drawbacks, in particular when the member to be actuated is a switch.
De manière à remédier notamment à ces inconvénients et en vue d'obtenir une course accrue, la présente invention propose un élément d'actionnement qui comprend en outre au moins une patte qui s'étend le long d'une face de ladite zone déformable, vers la partie centrale de cette dernière, et dont l'extrémité extérieure est fixée sur ladite face, de telle sorte que, les bords opposés de ladite zone déformable et l'extrémité libre de ladite patte étant respectivement en appui entre un sυpport et un organe à actionner, l'extrémité libre de ladite patte s'éloigne ou se rapproche de ladite tone déformable iore de le déformation dp. cette derniére, l'amplitude résultante du mouvement de l'extrémité libre de ladite patte étant plus grande que l'amplitude de déformation de ladite zone déformable,In order to remedy these drawbacks in particular and with a view to obtaining an increased stroke, the present invention provides an actuating element which further comprises at least one tab which extends along one face of said deformable zone, towards the central part of the latter, and the outer end of which is fixed on said face, so that, the opposite edges of said deformable zone and the free end of said tab being respectively in support between a support and a member to be actuated, the free end of said tab moves away from or approaches said deformable tone iore from the deformation dp. the latter, the amplitude resulting from the movement of the free end of said tab being greater than the amplitude of deformation of said deformable zone,
Selon la présente invention, l'élément d 'actionnement peut avantageusement comprendre au moins deux pattes opposées qui sont fixées par une extrémité sur une face de ladite zone déformable et qui s'étendent vers la partie centrale de cette dernière.According to the present invention, the actuating element can advantageously comprise at least two opposite tabs which are fixed by one end on one face of said deformable zone and which extend towards the central part of the latter.
Selon un autre objet de la présente invention, ladite pièce mince peut être de constitution différente. Dans une variante, cette pièce mince peut être déformable élaεtiquement. Dans une autre variante, ladile piéce peul êIre constituée par un bileme, Dans une autre variante également, ladite pièce mince peut présenter une zone déformable dans le sens de son épaisseur de manière à occuper deux positions extrêmes arquées situées de part et d'autre d'un plan médian.According to another object of the present invention, said thin piece can be of different constitution. Alternatively, this thin piece may be elastically deformable. In another variant, the said piece may be constituted by a bimetal, In another variant also, said thin piece may have a deformable zone in the direction of its thickness so as to occupy two arcuate extreme positions located on either side of a median plane.
Selon un autre objet de la présente invention, l'élément d'actionnement peut comprendre au moins un empilage comprenant deux pièces minces opposées munies respectivement d'au moins deux pattes opposées, disposées de telle sorte que les extrémités libres des pattes portées par l'une desdites pièces minces soit en appui sur les extrémités libres des pattes portées par l'autre pièce mince.According to another object of the present invention, the actuating element can comprise at least one stack comprising two opposite thin parts provided respectively with at least two opposite legs, arranged so that the free ends of the legs carried by the one of said thin pieces is supported on the free ends of the tabs carried by the other thin piece.
Dans une variante de réalisation selon un autre objet de la présente invention, ladite pièce mince est constituée par un disque, ladite ou lesdites pattes s'étendant radialement à ce dernier. Selon un autre objet de la présente invention, l'élément d'actionnement comprend une couronne fixée sur l'une des faces de ladite pièce mince en forme de disque et munie d'une multiplicité de pattes s'étendant radialement vers la partie centrale de cette pièce mince en forme de disque. Selon un autre objet de la présente invention, ladite pièce mince présente un passage dans la partie centrale de sa zone déformable, la ou lesdites pattes s'étendant sensiblement jusqu'au bord de ce passage.In an alternative embodiment according to another object of the present invention, said thin piece is constituted by a disc, said one or more tabs extending radially to the latter. According to another object of the present invention, the actuating element comprises a crown fixed to one of the faces of said thin disc-shaped part and provided with a multiplicity of legs extending radially towards the central part of this thin disc-shaped piece. According to another object of the present invention, said thin part has a passage in the central part of its deformable zone, the one or more tabs extending substantially to the edge of this passage.
Selon un autre objet de la présente invention, la ou lesdites pattes peuvent avantageusement être constituées par un bilame se déformant dans le sens de l'épaisseur de ladite pièce mince et dans le même sens.According to another object of the present invention, the said tab or tabs can advantageously be constituted by a bimetallic strip deforming in the thickness direction of the said thin part and in the same direction.
La présente invention sera mieux comprise à l'étude d'éléments d' actionnement décrits à titre d'exemples non limitatifs et illustrés par le dessin sur lequel :The present invention will be better understood from the study of actuating elements described by way of nonlimiting examples and illustrated by the drawing in which:
- la figure 1 représente en vue de dessus un premier élément d'actionne selon la présente invention;- Figure 1 shows a top view of a first actuating element according to the present invention;
- la figure 2 représente une coupe de l'élément d'actionnement de la figure 1 dans une première position; - la figure 3 représente une coupe de l'élément d'actionnement de la figure 1 dans une seconde position; - la figure 4 représente, en coupe, un autre élément d'actionnement selon la présente invention, dans une première position, monté dans un boîtier d'interrupteur;- Figure 2 shows a section of the actuating element of Figure 1 in a first position; - Figure 3 shows a section of the actuating element of Figure 1 in a second position; - Figure 4 shows, in section, another actuating element according to the present invention, in a first position, mounted in a switch housing;
- la figure 5 représente, en coupe, l'élément d'actionnement de la figure 4, dans une seconde position;- Figure 5 shows, in section, the actuating element of Figure 4, in a second position;
- la figure 6 représente, en vue de dessus, un autre élément d'actionnement selon la présente invention;- Figure 6 shows, in top view, another actuating element according to the present invention;
- et la figure 7 représente, en coupe, un empilage de plusieurs éléments d'actionnement semblables à celui de la figure 6. En se reportant aux figures 1 à 3, on voit qu'on a représenté un élément d 'actionnement d'une manière générale par la référence 1 qui comprend une pièce mince 2 en forme de disque qui est en un matériau déformable élastiquement, dans le sens de son épaisseur, de manière à occuper une première position stable arquée ou bombée visible sur la figure 2 et une deuxième position instable visible sur la figure 3 dans laquelle elle est arquée ou bombée de l'autre côté de son plan médian cette pièce mince- And Figure 7 shows, in section, a stack of several actuating elements similar to that of Figure 6. Referring to Figures 1 to 3, we see that there is shown an actuating element of a generally by the reference 1 which comprises a thin piece 2 in the form of a disc which is made of an elastically deformable material, in the direction of its thickness, so as to occupy a first stable arcuate or domed position visible in FIG. 2 and a second unstable position visible in Figure 3 in which it is arched or curved on the other side of its median plane this thin part
2 est adaptée pour passer de sa position stable à sa position instable par exemple en appuyant sur sa partie centrale et revenir à sa position stable par le fait de son élasticité. Il en résulte que l'amplitude maximum du mouvement de cette pièce mince 2 en forme de disque correspond à l'amplitude du déplacement de sa partie centrale.2 is adapted to pass from its stable position to its unstable position for example by pressing on its central part and return to its stable position by the fact of its elasticity. As a result, the maximum amplitude of movement of this thin disc-shaped piece 2 corresponds to the amplitude of the displacement of its central part.
L'élément d'actionnement 1 comprend en outre deux pattes opposées 3 et 4 qui s'étendent radialement au disque 2 et dont leur extrémité extérieure est fixée sur la face concave 5 de ce disque 2 lorsque ce dernier est dans sa position stable visible sur la figure 2, par l'intermédiaire de rivets 6 et 7, ces pattesThe actuating element 1 further comprises two opposite tabs 3 and 4 which extend radially to the disc 2 and whose outer end is fixed to the concave face 5 of this disc 2 when the latter is in its stable position visible on Figure 2, via rivets 6 and 7, these tabs
3 et 4 s' étendant l'une vers l'autre le long de la face 5 de telle sorte que leurs extrémités adjacentes 8 et 9 sont situées dans la partie centrale de la pièce mince 2 en forme de disque.3 and 4 extending towards each other along the face 5 so that their adjacent ends 8 and 9 are located in the central part of the thin piece 2 in the form of a disc.
Lorsque la pièce mince 2 en forme de disque est déformée, comme on l'a vu précédemment, de sa position stable visible sur la figure 2 jusqu'à sa position instable visible sur la figure 3, et inversement, les extrémités libres 8 et 9 des pattes 3 etWhen the thin disc-shaped piece 2 is deformed, as seen above, from its stable position visible in FIG. 2 to its unstable position visible in FIG. 3, and vice versa, the free ends 8 and 9 legs 3 and
4 s'éloignent de la face 5 de la pièce mince 2 en forme de disque sur laquelle elles sont fixées, et inversement. Il s'ensuit que l'amplitude résultante du mouvement des extrémités libres 8 et4 move away from the face 5 of the thin piece 2 in the form of a disc on which they are fixed, and vice versa. It follows that the resulting amplitude of the movement of the free ends 8 and
9 des pattes opposées 3 et 4 est plus grande que l'amplitude de déformation de la pièce mince 2 en forme de disque. En se reportant maintenant aux figures 4 et 5, on va décrire une application d'un élément en forme de disque repéré d'une manière générale par la référence 10 qui est de structure équivalente à celle de l'élément d'actionnement 1 représenté sur les figures 1 à 3. L'élément d'actionnement 10 comprend une pièce mince en forme de disque 11 constituée de deux disques 12 et 13 accolées de manière à constituer un bilame susceptible de se déformer en fonction de la température dans le sens de son épaisseur de manière lente ou rapide. L'élément d'actionnement 10 comprend en outre deux pattes opposées 14 et 15 qui sont fixées, comme dans l'exemple précédent, sur l'une des faces de la pièce mince en forme de disque 11 et qui, cette fois, sont chacune constituée par deux lames 16,17 et 18, 19 accolées de manière à constituer des bilames susceptibles de se déformer en fonction de la température dans le sens de l'épaisseu de la pièce mince en forme de disque 11 et dans le même sens. Dans cet exemple, les extrémités extérieures des deux pattes 14 et 15 sont fixées à la pièce mince en forme de disque 11 par collage. Le bord périphérique de la pièce mince en forme de disque 11 est en appui sur le couvercle 20 d'un boîtier d'interrupteur 21 et les extrémités libres des pattes 14 et 15 sont en appui contre l'extrémité d'un poussoir 22 adapté pour coulisser dans le boîtier9 of the opposite lugs 3 and 4 is greater than the amplitude of deformation of the thin piece 2 in the form of a disc. Referring now to Figures 4 and 5, we will describe an application of a disc-shaped element generally identified by the reference 10 which is of equivalent structure to that of the actuating element 1 shown in Figures 1 to 3. The actuating element 10 comprises a thin disc-shaped part 11 consisting of two discs 12 and 13 joined so as to form a bimetallic strip capable of deformation as a function of the temperature in the direction of its thickness slowly or quickly. The actuating element 10 further comprises two opposite tabs 14 and 15 which are fixed, as in the previous example, on one of the faces of the thin disc-shaped piece 11 and which, this time, are each constituted by two blades 16, 17 and 18, 19 joined so as to constitute bimetallic strips liable to deform as a function of the temperature in the thickness direction of the thin disc-shaped piece 11 and in the same direction. In this example, the outer ends of the two legs 14 and 15 are fixed to the thin disc-shaped part 11 by gluing. The peripheral edge of the thin disc-shaped part 11 is supported on the cover 20 of a switch box 21 and the free ends of the tabs 14 and 15 are pressed against the end of a pusher 22 adapted for slide in the housing
21 dans le sens de l'épaisseur de la pièce mince en forme de disque 11. L'autre extrémité de ce poussoir 22 est susceptible de déplacer l'élément mobile 23 d'un interrupteur repéré d'une manière générale par la référence 24 et monté dans le boîtier 21, à l'encontre d 'un ressort 25.21 in the thickness direction of the thin disc-shaped piece 11. The other end of this pusher 22 is capable of displacing the movable element 23 of a switch generally identified by the reference 24 and mounted in the housing 21, against a spring 25.
Lors d'un changement de température, l'élément d'actionneWhen the temperature changes, the operating element
10 se déforme de manière à passer de sa position visible sur la figure 4 à sa position visible sur la figure 5 ou inversement, ces changements de position correspondant aux changements de position de l'élément d'actionnement 1 vu précédemment en référence aux figures 2 et 3, avec accroissement de l'amplitude du mouvement de la pièce mince 11 en forme de disque grâce à la prévision des pattes opposées 14 et 15. A noter en outre que les déformations des pattes 14 et 15 constituées de bilames amplifient également la déformation de la pièce mince en forme de disque 11. Se faisant, la déformation de l'élément d'actionnement 10 provoque l'actionnement de l'interrupteur 24, dans le sens de son ouverture ou de sa fermeture, par déplacement de son organe mobile 23 par l'intermédiaire du poussoir 22. En se reportant maintenant à la figure 6, on voit qu'on a représenté un élément d'actionnement repéré d'une manière générale par la référence 26 qui comprend une pièce mince en forme de disque 27 constituant comme précédemment un bilame, sur l'une des faces de laquelle est fixée une couronne 28 par l'intermédiaire de quatre rivets 29, cette couronne étant munie de quatre pattes10 deforms so as to pass from its visible position in FIG. 4 to its visible position in FIG. 5 or vice versa, these changes in position corresponding to the changes in position of the actuating element 1 seen previously with reference to FIGS. 2 and 3, with an increase in the amplitude of movement of the thin piece 11 in the form of a disc thanks to the provision of the opposite lugs 14 and 15. Note also that the deformations of the legs 14 and 15 made up of bimetallic strips also amplify the deformation of the thin disc-shaped piece 11. In doing so, the deformation of the actuating element 10 causes the actuation of the switch 24 direction of its opening or closing, by displacement of its movable member 23 by means of the pusher 22. Referring now to FIG. 6, it can be seen that an actuating element has been identified in a way general by the reference 26 which comprises a thin disc-shaped part 27 constituting as previously a bimetallic strip, on one of the faces of which is fixed a crown 28 by means of four rivets 29, this crown t has four legs
30 régulièrement réparties qui s'étendent radialement vers la partie centrale de la pièce mince en forme de disque 27 et dont les extrémité libres intérieures 31 vont jusqu'au bord d'un passage central 32 prévu dans la pièce mince en forme de disque 27. Cet élément d'actionnement 26 est adapté pour se déformer de la même manière que les éléments d'actionnement 1 et 10 décrits précédemment.30 regularly distributed which extend radially towards the central part of the thin disc-shaped part 27 and whose inner free ends 31 go as far as the edge of a central passage 32 provided in the thin disc-shaped part 27. This actuating element 26 is adapted to deform in the same manner as the actuating elements 1 and 10 described above.
En se reportant à la figure 7, on voit qu'on a représenté un empilage de quatre éléments d'actionnement 26, par paires, de telle sorte que les extrémités libres 31 des pattes 30 entre deux disques adjacents soient en appui les unes sur les autres et que les bords périphériques des pièces minces en forme de disque 27 des deux éléments d'actionnement 26 d'extrémité de l'empilage soient en appui l'une sur un support 33 et l'autre sur un plateau 34 relié à une tige à actionner 35 qui s'étend au travers des passages centraux 32 des quatre éléments d'actionnement empilés 26 et au travers du support 33, les éléments d'actionnement 26 s'étendant autour de la tige 35 et étant centrés et guidés par cette dernière. Lors d'un changement de température, les quatre éléments d'actionnement 26 se déforment dans le sens de leur épaisseur comme on l'a déjà vu précédemment et permettent le déplacement du plateau 34 et en conséquence de la tige 35 par rapport au support 33, l'amplitude de ce déplacement correspondant à l'addition de l'amplitude des déformations des quatres éléments d' actionnement 26 empilés.Referring to Figure 7, we see that there is shown a stack of four actuating elements 26, in pairs, so that the free ends 31 of the legs 30 between two adjacent discs are supported one on the other and that the peripheral edges of the thin disc-shaped pieces 27 of the two actuating elements 26 of the end of the stack are supported one on a support 33 and the other on a plate 34 connected to a rod to be actuated 35 which extends through the central passages 32 of the four stacked actuating elements 26 and through the support 33, the actuating elements 26 extending around the rod 35 and being centered and guided by the latter . During a temperature change, the four actuating elements 26 deform in the direction of their thickness as we have already seen previously and allow the movement of the plate 34 and consequence of the rod 35 relative to the support 33, the amplitude of this displacement corresponding to the addition of the amplitude of the deformations of the four actuating elements 26 stacked.
La présente invention ne se limite évidemment pas aux exemples ci-dessus décrits. En effet, l'effet des pattes associées à la pièce mince déformable dans le sens de son épaisseur pourrait être atteint avec des pièces minces de formes différentes et en particulier avec des pièces minces en forme de lamelles par exemple rectangulaire deformables elastiquement ou constituant des bilames. The present invention is obviously not limited to the examples described above. Indeed, the effect of the legs associated with the thin piece deformable in the direction of its thickness could be achieved with thin pieces of different shapes and in particular with thin pieces in the form of strips, for example rectangular elastically deformable or constituting bimetallic strips .
