Abstract

The control has a head (12) of a pusher (3) movable towards an output position which is opposite to an open position with respect to a rest position. Elastic return units (15) stress the head of the pusher towards the output position so that the head has an autonomous ascending movement. Detection units detect the position occupied by the head between the output and open positions.

La présente invention concerne le domaine technique des télécommandes pour engins de travaux publics, notamment les télécommandes dites étectro-hydrauliques.The present invention relates to the technical field of remote controls for public works machinery, including so-called electro-hydraulic remote controls.

L'invention est plus particulièrement relative aux télécommandes qui sont destinées à permettre la commande d'un ou plusieurs organes récepteurs, notamment utilisateurs de fluide sous pression, à partir d'une poignée manoeuvrée par l'opérateur pour transmettre un signal de commande auxdits organes récepteurs hydrauliques.The invention relates more particularly to remote controls which are intended to allow the control of one or more receiving members, in particular users of fluid under pressure, from a handle operated by the operator to transmit a control signal to said organs. hydraulic receivers.

Les télécommandes habituellement rencontrées à bord des engins de travaux publics, notamment celle décrite dans le document DE19935101 comportent :

  • un corps qui comprend au moins une cavité s'étendant entre une extrémité débouchante sur au moins une face supérieure du corps et un fond opposé à l'extrémité débouchante,
  • au moins un premier poussoir qui s'étend entre une tête et un pied, qui est monté coulissant en mouvement de va-et-vient dans ladite au moins une cavité du corps selon une direction axiale entre une position de repos et une position enfoncée, et qui est destiné à permettre la commande d'au moins un premier récepteur extérieur à la télécommande, et
  • une poignée qui comprend une jupe transversale et qui est montée basculante par rapport au corps en regard de la face supérieure dudit corps pour commander le mouvement de va-et-vient dudit premier poussoir, la jupe étant en appui simple sur la tête dudit poussoir, et l'axe de la poignée formant avec l'axe du poussoir un angle aigu variable, la poignée s'étendant parallèlement à l'axe du poussoir lorsqu'elle se trouve en position de repos.
Remote controls usually encountered on board public works machinery, in particular that described in the document DE19935101 include:
  • a body which comprises at least one cavity extending between an open end on at least one upper face of the body and a bottom opposite the open end,
  • at least one first pusher which extends between a head and a foot, which is slidably reciprocated in said at least one body cavity in an axial direction between a rest position and a depressed position, and which is intended to allow the control of at least a first external receiver on the remote control, and
  • a handle which comprises a transverse skirt and which is pivotally mounted relative to the body facing the upper face of said body to control the back and forth movement of said first pusher, the skirt being in simple support on the head of said pusher, and the axis of the handle forming with the axis of the pusher a variable acute angle, the handle extending parallel to the axis of the pusher when in the rest position.

Même si de telles télécommandes permettent de commander les mouvements d'organes récepteurs avec satisfaction, elles nécessitent de nombreuses pièces constitutives dans la mesure où elles doivent posséder plusieurs poussoirs chacun équipé de moyens de détection, qui détectent la position occupée de chacun des poussoirs entre leur position de repos et leur position enfoncée. Le prix de revient de telles télécommandes est donc onéreux et leur fiabilité peut être affectée par l'une des nombreuses pièces constitutives.Even if such remote controls make it possible to control the movements of receiving organs with satisfaction, they require many component parts in that they must have several pushers each equipped with detection means, which detect the occupied position of each of the pushers between them. rest position and their depressed position. The cost price of such remotes is therefore expensive and their reliability can be affected by one of the many component parts.

La présente invention a donc pour but de remédier aux inconvénients précités en fournissant une télécommande dont le nombre de pièces constitutives est réduit tout en conservant les mêmes fonctionnalités.
A cet effet, selon la présente invention, la télécommande du type précité est essentiellement caractérisée en ce qu'au moins la tête du premier poussoir est en outre mobile vers une position sortie qui est opposée à la position enfoncée par rapport à ladite position de repos,
en ce que des premiers moyens de rappel élastiques sollicitent la tête du poussoir vers sa position sortie, de sorte qu'au moins la tête du premier poussoir possède un mouvement ascendant autonome pour suivre la jupe lorsque la poignée est basculée, et
en ce que la télécommande comprend en outre des moyens de détection pour détecter toute position occupée par la tête du premier poussoir entre ses positions sortie et enfoncée.The present invention therefore aims to overcome the aforementioned drawbacks by providing a remote control whose number of component parts is reduced while maintaining the same functionality.
For this purpose, according to the present invention, the remote control of the aforementioned type is essentially characterized in that at least the head of the first pusher is further movable to an extended position which is opposite the depressed position relative to said rest position ,
in that first elastic return means urge the pusher head towards its extended position, so that at least the head of the first pusher has an autonomous upward movement to follow the skirt when the handle is tilted, and
in that the remote control further comprises detection means for detecting any position occupied by the head of the first pusher between its output and depressed positions.

Ainsi, grâce à ces dispositions, le nombre de poussoirs équipés de moyens de détection est réduit puisqu'un seul poussoir est nécessaire en lieu et place de deux poussoirs présents dans les télécommandes de l'art antérieur.Thus, thanks to these provisions, the number of pushers equipped with detection means is reduced since only one push is needed instead of two push buttons present in the remote controls of the prior art.

Avantageusement, les moyens de détection sont du type sans contact mécanique.Advantageously, the detection means are of the type without mechanical contact.

De préférence, les moyens de détection comprennent un aimant qui est solidaire en mouvement de la tête du poussoir.Preferably, the detection means comprise a magnet which is integral in movement with the pusher head.

Selon une possibilité, la cavité est étagée et comprend un premier épaulement sensiblement transversal au déplacement du premier poussoir, et ledit poussoir comprend un tronçon intermédiaire qui est solidaire en mouvement de la tête et du pied du poussoir, qui est situé entre sa tête et son pied, et qui délimite une butée haute et une butée basse, la butée haute venant en appui contre le premier épaulement dans la position sortie du poussoir et la butée basse venant en appui contre le fond de la cavité dans la position enfoncée dudit poussoir.According to one possibility, the cavity is stepped and comprises a first shoulder substantially transverse to the displacement of the first pusher, and said pusher comprises an intermediate portion which is integral in movement with the head and the foot of the pusher, which is located between its head and its foot, and delimiting an upper stop and a lower stop, the upper abutment bearing against the first shoulder in the extended position of the pusher and the lower abutment bearing against the bottom of the cavity in the depressed position of said pusher.

De préférence, les premiers moyens de rappel sont logés dans la cavité.Preferably, the first return means are housed in the cavity.

Encore de préférence, les premiers moyens de rappel comprennent une collerette portée par le tronçon intermédiaire au voisinage de la butée haute, et un premier ressort de compression interposé entre la collerette et le fond de la cavité.Still preferably, the first return means comprise a flange carried by the intermediate section in the vicinity of the upper stop, and a first compression spring interposed between the flange and the bottom of the cavity.

Selon une autre possibilité, la cavité comprend un épaulement sensiblement transversal au déplacement du premier poussoir, et ledit poussoir comprend une tête et un pied solidaires en mouvement et mobiles en translation selon l'axe du poussoir par rapport à un tronçon intermédiaire, qui est situé entre la tête et le pied, et qui délimite une butée haute et une butée basse, la butée haute venant en appui contre l'épaulement lorsque la tête du poussoir est entre sa position de repos et sa position sortie et la butée basse venant en appui contre le fond de la cavité dans la position enfoncée dudit poussoir.According to another possibility, the cavity comprises a shoulder substantially transverse to the displacement of the first pusher, and said pusher comprises a head and a foot integral in motion and movable in translation along the axis of the pusher relative to an intermediate section, which is located between the head and the foot, and which delimits a high stop and a low stop, the high stop abutting against the shoulder when the head of the pusher is between its rest position and its extended position and the bottom stop bearing against the bottom of the cavity in the depressed position of said pusher.

De préférence, les premiers moyens de rappel élastiques sont logés entre la tête du poussoir et le tronçon intermédiaire du poussoir.Preferably, the first elastic return means are housed between the pusher head and the intermediate portion of the pusher.

Selon un mode de réalisation, les premiers moyens de rappel élastiques comprennent un premier ressort de compression interposé entre la tête du poussoir et le tronçon intermédiaire du poussoir.According to one embodiment, the first elastic return means comprise a first compression spring interposed between the pusher head and the intermediate portion of the pusher.

Avantageusement, des deuxièmes moyens de rappel élastique sont logés dans la cavité pour rappeler le premier poussoir depuis sa position enfoncée vers sa position de repos.Advantageously, second elastic return means are housed in the cavity to return the first pusher from its depressed position to its rest position.

Selon une possibilité, les deuxième moyens de rappel comprennent un anneau concentrique au premier poussoir, un deuxième ressort de compression qui est interposé entre l'anneau et le fond de la cavité, ainsi qu'un relief périphérique solidaire du premier poussoir et destiné à venir en appui sur l'anneau, la cavité comprenant en outre un deuxième épaulement sur lequel l'anneau est en butée dans la position de repos du premier poussoir.According to one possibility, the second return means comprise a ring concentric with the first pusher, a second compression spring which is interposed between the ring and the bottom of the cavity, and a peripheral relief integral with the first pusher and intended to come resting on the ring, the cavity further comprising a second shoulder on which the ring abuts in the rest position of the first pusher.

Selon une autre possibilité, les deuxièmes moyens de rappel comprennent une collerette portée par le tronçon intermédiaire au voisinage de la butée haute, et un deuxième ressort de compression interposé entre la collerette et le fond de la cavité.According to another possibility, the second return means comprise a collar carried by the intermediate section in the vicinity of the upper stop, and a second compression spring interposed between the collar and the bottom of the cavity.

Avantageusement, un deuxième poussoir est monté dans une deuxième cavité du corps, le deuxième poussoir étant sollicité élastiquement par un troisième ressort de compression de sorte que l'effort à exercer sur la poignée pour enfoncer l'un des premier et deuxième poussoirs soit sensiblement constant.Advantageously, a second pusher is mounted in a second cavity of the body, the second pusher being resiliently biased by a third compression spring so that the force exerted on the handle to drive one of the first and second pusher is substantially constant. .

Selon un mode de réalisation, la deuxième cavité est symétrique de la première cavité par rapport à l'axe de la poignée dans la position de repos.According to one embodiment, the second cavity is symmetrical with the first cavity relative to the axis of the handle in the rest position.

Avantageusement, au moins la tête du second poussoir est mobile vers une position sortie qui est opposée à la position enfoncée par rapport à ladite position de repos et des moyens de rappel élastiques sollicitent la tête du poussoir vers sa position sortie, de sorte qu'au moins la tête du second poussoir possède un mouvement ascendant autonome.Advantageously, at least the head of the second pusher is movable to an extended position which is opposed to the depressed position relative to said rest position and elastic return means urge the head of the pushing to its extended position, so that at least the head of the second pusher has an autonomous upward movement.

Selon un mode de réalisation, le pied du premier poussoir est monté traversant dans le fond de la cavité et porte intérieurement l'aimant.According to one embodiment, the foot of the first pusher is mounted through the bottom of the cavity and internally carries the magnet.

Avantageusement, un capteur à effet Hall est monté dans le corps de la télécommande, en regard du déplacement de l'aimant entre les positions enfoncée et sortie du premier poussoir.Advantageously, a Hall effect sensor is mounted in the body of the remote control, facing the movement of the magnet between the depressed and output positions of the first pusher.

Selon un mode de réalisation, le deuxième poussoir est implanté à l'opposé du premier poussoir par rapport à l'axe de la poignée.According to one embodiment, the second pusher is located opposite the first pusher relative to the axis of the handle.

Avantageusement, le capteur à effet Hall est noyé dans de la résine pour être placé dans une région étanche.Advantageously, the Hall effect sensor is embedded in the resin to be placed in a sealed region.

In any case, the invention will be better understood from the description which follows, with reference to the attached schematic drawing showing, by way of non-limiting example, three embodiments of the remote control according to the present invention.
  • The figure 1 is a longitudinal sectional view of the remote control according to a first embodiment.

La figure 1 représente une télécommande 1 pour engins de travaux publics qui comprend, de manière connue en soi, un corps 2, au moins un premier poussoir 3 qui est monté coulissant dans le corps 2 et une poignée 4 qui est montée basculante par rapport à ce corps pour commander les mouvements de va-et-vient du premier poussoir 3 à l'intérieur du corps 2.The figure 1 represents a remote control 1 for public works machinery which comprises, in a manner known per se, a body 2, at least a first pusher 3 which is slidably mounted in the body 2 and a handle 4 which is pivotally mounted relative to this body for control the back and forth movements of the first pusher 3 inside the body 2.

Le premier poussoir 3 est monté coulissant à l'intérieur d'une première cavité 5 qui s'étend entre une extrémité débouchante 6 sur au moins une face supérieure 7 du corps 2 et un fond 8 opposé à cette extrémité débouchante 6.The first pusher 3 is slidably mounted inside a first cavity 5 which extends between a through end 6 on at least one upper face 7 of the body 2 and a bottom 8 opposite this open end 6.

Le corps 2 est d'axe longitudinal X-X et le premier poussoir 3 coulisse parallèlement à cet axe X-X.The body 2 has a longitudinal axis X-X and the first pusher 3 slides parallel to this axis X-X.

La poignée 4 est montée basculante par rapport au corps 2, en regard de la face supérieure 7 de ce corps pour commander les mouvements de va-et-vient dudit premier poussoir 3. Cette poignée 4 est d'axe Y-Y et possède une jupe transversale 10 qui permet de commander ledit au moins un premier poussoir 3. L'axe Y-Y de la poignée 4 forme avec l'axe du poussoir 3 un angle aigu variable qui est fonction de la position à donner au poussoir. Lorsque la poignée 4 est en position de repos, elle s'étend selon l'axe X-X du corps 2 comme cela est représenté aux figures 1 et 2. Les positions de la poignée représentée aux figures 3 et 5 permettent de commander ledit premier poussoir 3 respectivement vers sa position enfoncée, et sa position sortie.The handle 4 is pivotally mounted relative to the body 2, facing the upper face 7 of the body to control the reciprocating movements of said first pusher 3. This handle 4 has a YY axis and has a transverse skirt 10 which makes it possible to control the at least one first pusher 3. The axis YY of the handle 4 forms with the axis of the pusher 3 a variable acute angle which is a function of the position to be given to the pusher. When the handle 4 is in the rest position, it extends along the axis XX of the body 2 as shown in FIGS. Figures 1 and 2 . The positions of the handle shown in figures 3 and 5 allow to control said first pusher 3 respectively to its depressed position, and its extended position.

A cet effet, ledit poussoir 3 s'étend entre une tête 12 et un pied 13. La tête 12 est montée en mouvement de va-et-vient au niveau de l'extrémité débouchante 6 du corps 2 de sorte que la jupe 10 de la poignée 4 est en simple appui sur cette tête 12. Le pied 13 du poussoir 3 est logé dans le fond 8 de la cavité 5 pour permettre la commande d'au moins un premier récepteur extérieur à la télécommande.For this purpose, said pusher 3 extends between a head 12 and a foot 13. The head 12 is mounted to move back and forth at the open end 6 of the body 2 so that the skirt 10 of the handle 4 is in simple support on the head 12. The foot 13 of the pusher 3 is housed in the bottom 8 of the cavity 5 to allow the control of at least a first external receiver to the remote control.

La tête 12 du premier poussoir 3 vient en butée sous la jupe 10 de la poignée 4 et est commandée entre sa position de repos telle que représentée aux figures 1 et 2, et sa position enfoncée telle que représentée aux figures 3 et 4, comme cela est bien connu dans l'état de la technique.The head 12 of the first pusher 3 comes into abutment under the skirt 10 of the handle 4 and is controlled between its rest position such that represented at Figures 1 and 2 , and its depressed position as shown in Figures 3 and 4 as is well known in the state of the art.

Selon une caractéristique essentielle de la présente invention, ce premier poussoir 3 est en outre mobile vers une position sortie telle que représentée aux figures 5 et 6, cette position sortie étant opposée à la position enfoncée par rapport à la position de repos.According to an essential characteristic of the present invention, this first pusher 3 is also movable towards an extended position as shown in FIGS. Figures 5 and 6 , this output position being opposite to the depressed position relative to the rest position.

A cet effet, la télécommande selon la présente invention possède des premiers moyens de rappel élastique 15 qui sont logés dans ta cavité 5 pour solliciter le premier poussoir 3 vers sa position sortie de manière à ce que ce poussoir possède un mouvement ascendant qui lui est propre. Au cours de ce mouvement ascendant, la poignée 4 est basculée de manière à dégager la tête 12 du poussoir 3 de sorte que cette tête 12 possède un mouvement ascendant pour suivre la jupe 10 sous la seule action des premiers moyens de rappel élastique 15.For this purpose, the remote control according to the present invention has first elastic return means 15 which are housed in the cavity 5 to urge the first pusher 3 towards its extended position so that the pusher has an upward movement of its own. . During this upward movement, the handle 4 is tilted so as to disengage the head 12 from the pusher 3 so that the head 12 has an upward movement to follow the skirt 10 under the sole action of the first elastic return means 15.

Par ailleurs, afin de commander ledit premier récepteur extérieur, la télécommande 1 comprend en outre des moyens de détection 17 qui permettent de détecter toute position occupée par ce premier poussoir 3 entre ses positions sortie et enfoncée.Furthermore, in order to control said first external receiver, the remote control 1 further comprises detection means 17 which detect any position occupied by the first pusher 3 between its output and depressed positions.

De préférence, la cavité 5 est étagée et comprend un premier épaulement 20 situé en dessous de l'extrémité débouchante 6 et qui s'étend sensiblement transversalement au déplacement du premier poussoir 3 c'est-à-dire, sensiblement perpendiculairement à l'axe X-X. Par ailleurs, le poussoir 3 possède un tronçon intermédiaire 22 qui est de plus gros diamètre que la tête 12 et le pied 13 de ce poussoir et qui est implanté sur la longueur dudit poussoir. Dans ce mode de réalisation, la tête 12, le pied 13 et le tronçon intermédiaire 22 sont solidaires en mouvement. Ce tronçon intermédiaire possède ainsi une face supérieure 23 qui délimite une butée haute et une face inférieure 24 qui délimite une butée basse. La face supérieure 23 est tournée en direction du premier épaulement 20 tandis que la face inférieure 24 est tournée en direction du fond 8 de la cavité 5.Preferably, the cavity 5 is stepped and comprises a first shoulder 20 located below the emergent end 6 and which extends substantially transversely to the displacement of the first pusher 3 that is to say, substantially perpendicular to the axis XX. Furthermore, the pusher 3 has an intermediate portion 22 which is larger in diameter than the head 12 and the foot 13 of the pusher and which is implanted along the length of said pusher. In this embodiment, the head 12, the foot 13 and the intermediate portion 22 are integral in motion. This intermediate section thus has an upper face 23 which delimits an upper stop and a lower face 24 which delimits a lower stop. The upper face 23 is turned towards the first shoulder 20 while the lower face 24 is turned towards the bottom 8 of the cavity 5.

Ainsi, lors des mouvements de va-et-vient du poussoir 3 à l'intérieur de cette cavité 5, la butée haute 23 est destinée à venir en appui contre le premier épaulement 20 comme cela est représenté aux figures 5 et 6 pour définir la position sortie de ce poussoir 3 tandis que la butée basse 24 est destinée à venir en appui contre le fond 8 de cette cavité dans la position enfoncée du poussoir comme cela est représenté aux figures 3 et 4.Thus, during the back and forth movements of the pusher 3 inside this cavity 5, the upper abutment 23 is intended to bear against the first shoulder 20 as shown in FIGS. Figures 5 and 6 to define the output position of this pusher 3 while the lower stop 24 is intended to bear against the bottom 8 of this cavity in the depressed position of the pusher as shown in FIGS. Figures 3 and 4 .

Les premiers moyens de rappel 15 comprennent de préférence une collerette 26 qui est portée par le tronçon intermédiaire 22, au voisinage de la butée haute 23, cette collerette étant tournée en direction du fond 8 de la cavité 5. Les premiers moyens de rappel élastique 15 comprennent également un premier ressort de compression 27 qui est interposé entre la collerette 26 et le fond 8 de la cavité 5. Ce ressort de compression 27 est d'un diamètre légèrement supérieur à celui du tronçon intermédiaire 22 de manière à être emmanché sur ce tronçon pour atteindre la collerette 26.The first return means 15 preferably comprise a collar 26 which is carried by the intermediate section 22, in the vicinity of the upper stop 23, this collar being turned towards the bottom 8 of the cavity 5. The first elastic return means 15 also comprise a first compression spring 27 which is interposed between the collar 26 and the bottom 8 of the cavity 5. This compression spring 27 is of a diameter slightly greater than that of the intermediate section 22 so as to be fitted on this section to reach the collar 26.

Ainsi, le premier poussoir 3 possède un mouvement ascendant qui est forcé par le premier ressort de compression 27 de sorte que lorsque la tête 12 de ce poussoir 3 est dégagée par la jupe 10 de la poignée 4, le poussoir 3 possède un mouvement ascendant vers sa position sortie grâce aux moyens de compression 27.Thus, the first pusher 3 has an upward movement which is forced by the first compression spring 27 so that when the head 12 of this pusher 3 is disengaged by the skirt 10 of the handle 4, the pusher 3 has an upward movement towards its output position through the compression means 27.

Par ailleurs, selon une autre caractéristique de l'invention, la télécommande 1 possède des deuxième moyens de rappel élastique 30 qui sont logés dans la cavité 5 pour rappeler ce premier poussoir 3 depuis sa position enfoncée telle que représentée aux figures 3 et 4, vers sa position de repos telle que représentée aux figures 1 et 2.Furthermore, according to another characteristic of the invention, the remote control 1 has second resilient return means 30 which are housed in the cavity 5 to recall the first pusher 3 from its depressed position as shown in FIGS. Figures 3 and 4 towards its rest position as shown in Figures 1 and 2 .

Comme le montrent plus particulièrement les figures 3 et 4, les deuxièmes moyens de rappel élastique 30 comprennent un anneau 31 qui est concentrique au premier poussoir 3, un deuxième ressort de compression 32 qui est interposé entre l'anneau 31 et le fond 8 de la cavité 5, ainsi qu'un relief périphérique 33 qui est solidaire en mouvement du premier poussoir 3 et qui est destiné à venir en appui sur l'anneau 31. Par ailleurs, la cavité 5 possède un deuxième épaulement 35 situé à un niveau intermédiaire entre le premier épaulement 20 et le fond 8 de la cavité 5. Le deuxième ressort de compression 32 sollicite l'anneau 31 en direction du deuxième épaulement 35 pour que cet anneau 31 vienne en butée contre ce deuxième épaulement lorsque le premier poussoir 3 est dans sa position de repos telle que représentée aux figures 1 et 2. Le deuxième épaulement 35 définit ainsi en quelque sorte la position de repos du poussoir 3.As shown more particularly by Figures 3 and 4 the second elastic return means 30 comprise a ring 31 which is concentric with the first pusher 3, a second compression spring 32 which is interposed between the ring 31 and the bottom 8 of the cavity 5, and a peripheral relief 33 which is secured in movement of the first pusher 3 and which is intended to rest on the ring 31. Furthermore, the cavity 5 has a second shoulder 35 located at an intermediate level between the first shoulder 20 and the bottom 8 of the cavity 5. The second compression spring 32 urges the ring 31 towards the second shoulder 35 so that this ring 31 abuts against this second shoulder when the first pusher 3 is in its rest position as shown in FIGS. Figures 1 and 2 . The second shoulder 35 thus defines, as it were, the rest position of the pusher 3.

Le poussoir 3 est ainsi en équilibre dans sa position de repos entre l'action exercée par la jupe 10 sur la tête 12 qui à tendance à enfoncer le poussoir 3, et l'action du premier ressort de compression et du deuxième ressort de compression 27 et 32. Dans cette position de repos, l'anneau 31 est en butée contre le deuxième épaulement 35 tandis que le relief périphérique 33 est en butée contre cet anneau 31 sous l'action de la poignée 4.The pusher 3 is thus in equilibrium in its rest position between the action exerted by the skirt 10 on the head 12 which tends to drive the pusher 3, and the action of the first compression spring and the second compression spring 27 and 32. In this rest position, the ring 31 is in abutment against the second shoulder 35 while the peripheral relief 33 abuts against this ring 31 under the action of the handle 4.

Lorsque le poussoir 3 est dans sa position enfoncée telle que représentée aux figures 3 et 4, la jupe 10 de la poignée 4 sollicite la tête 12 du poussoir 3 vers le bas de sorte que le tronçon intermédiaire 22 entraîne en mouvement descendant l'anneau concentrique 31 et comprime les ressorts de compression 27 et 32 jusqu'à ce que ce tronçon intermédiaire 22 soit en butée basse contre le fond 8 de la cavité 5.When the pusher 3 is in its depressed position as shown in FIGS. Figures 3 and 4 , the skirt 10 of the handle 4 urges the head 12 of the pusher 3 downwards so that the intermediate portion 22 drives the concentric ring 31 in downward movement and compresses the compression springs 27 and 32 until this section intermediate 22 is in low abutment against the bottom 8 of the cavity 5.

A l'opposé, lorsque le poussoir 3 est dans sa position de sortie telle que représentée aux figures 5 et 6, la tête 12 de ce poussoir a été dégagée par la jupe 10 de la poignée 4 de sorte que le tronçon intermédiaire 22 est venue en butée haute contre le premier épaulement 20 sous l'action du premier ressort de compression 27. Au cours du mouvement de retour depuis la position enfoncée vers la position sortie, les ressorts de compression 27 et 32 se détendent. L'anneau concentrique 31 vient en butée contre le deuxième épaulement 35 de la cavité 5 tandis que le relief périphérique 33 n'est plus en contact avec l'anneau 31 lorsque le poussoir passe de sa position de repos vers sa position sortie.In contrast, when the pusher 3 is in its output position as shown in FIGS. Figures 5 and 6 , the head 12 of this pusher has been disengaged by the skirt 10 of the handle 4 so that the intermediate portion 22 has come into high abutment against the first shoulder 20 under the action of the first compression spring 27. During the movement back from the depressed position to the extended position, the compression springs 27 and 32 expand. The concentric ring 31 abuts against the second shoulder 35 of the cavity 5 while the peripheral relief 33 is no longer in contact with the ring 31 when the pusher passes from its rest position to its extended position.

En fonction de l'inclinaison de la poignée 4, le poussoir 12 occupe toute position entre sa position enfoncée et sa position sortie.Depending on the inclination of the handle 4, the pusher 12 occupies any position between its depressed position and its extended position.

Le pied 13 du poussoir 3 s'étend au-delà du fond 8 de la cavité 5 de manière à traverser ce fond en mouvement de va-et-vient entre ses positions sortie et enfoncée.The foot 13 of the pusher 3 extends beyond the bottom 8 of the cavity 5 so as to cross the bottom reciprocating between its output and depressed positions.

De préférence, les moyens de détection 17 sont du type sans contact mécanique et comprennent par exemple un aimant 40 qui est solidaire en mouvement du poussoir 3 en étant monté à l'intérieur du pied 13 de ce poussoir, ainsi qu'un capteur à effet Hall 41 qui est monté dans le corps 2 de la télécommandé 1, en regard du déplacement de l'aimant 40 entre les positions enfoncée et sortie du premier poussoir 3. Plus précisément, le capteur à effet Hall 41 est monté dans le corps 2, au-delà du fond 8 de la cavité 5. Ainsi, ce capteur 41 peut être noyé dans une matière telle que de la résine pour le rendre étanche.Preferably, the detection means 17 are of the type without mechanical contact and comprise for example a magnet 40 which is integral in movement of the pusher 3 being mounted inside the foot 13 of this pusher, as well as an effect sensor. Hall 41 which is mounted in the body 2 of the remote control 1, facing the displacement of the magnet 40 between the depressed and output positions of the first pusher 3. More specifically, the Hall effect sensor 41 is mounted in the body 2, beyond the bottom 8 of the cavity 5. Thus, this sensor 41 may be embedded in a material such as resin to make it waterproof.

Par ailleurs, même si ce premier poussoir 3 permet de commander à lui seul un premier organe récepteur, un deuxième poussoir 50 est implanté dans le corps 2 de la télécommande 1 afin de permettre l'équilibre de la poignée 4. Ce deuxième poussoir 50 est un poussoir passif dans la mesure où il ne permet pas de transmettre un signal de commande à un organe récepteur. Il est implanté dans une cavité 51 ménagée dans le corps 2 à l'opposé de la première cavité 5 par rapport à l'axe de la poignée 4. Ce deuxième poussoir 50 possède également une tête 52 venant en appui sous la jupe 10 de la poignée 4 et un pied 53. Ce pied 53 vient en butée dans le fond de la deuxième cavité 51 et possède une collerette 55 qui vient en butée contre la partie haute 56 de la cavité 51. Cette cavité 51 s'étend parallèlement à l'axe X-X et entre les niveaux définis par le fond 8 de la première cavité 5 et la position de repos définie par le deuxième épaulement 35 de la première cavité 5.Moreover, even if this first pusher 3 can control alone a first receiving member, a second pusher 50 is implanted in the body 2 of the remote control 1 to allow the balance of the handle 4. This second pusher 50 is a passive pusher as far as it does not allow to transmit a control signal to a receiver member. It is implanted in a cavity 51 formed in the body 2 opposite the first cavity 5 with respect to the axis of the handle 4. This second pusher 50 also has a head 52 bearing under the skirt 10 of the handle 4 and a foot 53. This foot 53 abuts in the bottom of the second cavity 51 and has a collar 55 which abuts against the upper portion 56 of the cavity 51. This cavity 51 extends parallel to the axis XX and between the levels defined by the bottom 8 of the first cavity 5 and the rest position defined by the second shoulder 35 of the first cavity 5.

Ce deuxième poussoir 50 est sollicité par un troisième ressort de compression 60 qui est interposé entre la collerette 55 et le fond de cette cavité de manière à solliciter élastiquement ce deuxième poussoir 50 et à provoquer pour l'opérateur, le même effort sur la poignée 4 pour enfoncer le premier poussoir 3 ou le deuxième poussoir 50.This second pusher 50 is biased by a third compression spring 60 which is interposed between the collar 55 and the bottom of this cavity so as to resiliently urge this second pusher 50 and to cause the operator the same effort on the handle 4 to depress the first pusher 3 or the second pusher 50.

Ainsi, seul le premier poussoir 3 est équipé de moyens permettant de commander un organe récepteur tandis que le deuxième poussoir 50 est simplement là pour la symétrie des efforts à exercer sur la poignée 4. Le nombre de pièces constitutives est ainsi réduit de manière à minimiser le prix de revient et les risques de défaillance technique.Thus, only the first pusher 3 is equipped with means for controlling a receiving member while the second pusher 50 is simply there for the symmetry of the forces to exert on the handle 4. The number of component parts is thus reduced so as to minimize the cost price and the risks of technical failure.

Par ailleurs, une liaison mécanique positive peut en outre être créée entre la tête 12 du poussoir 3 pour pallier à une éventuelle défaillance de l'un des ressorts de compression ou pour le cas où le poussoir 3 resterait coincé lors de son mouvement ascendant.Furthermore, a positive mechanical connection can also be created between the head 12 of the pusher 3 to overcome a possible failure of one of the compression springs or for the case where the pusher 3 remains stuck during its upward movement.

Selon un second mode de réalisation de l'invention, représenté sur les figures 7 à 9 la télécommande 1 pour engins de travaux publics comprend, comme dans le premier mode de réalisation, de manière connue en soi, un corps 2, au moins un premier poussoir 62 qui est monté coulissant dans le corps 2 et une poignée 4 qui est montée basculante par rapport à ce corps pour commander les mouvements de va-et-vient du premier poussoir 62 à l'intérieur du corps 2.According to a second embodiment of the invention, represented on the Figures 7 to 9 the remote control 1 for public works machinery comprises, as in the first embodiment, in a manner known per se, a body 2, at least one first pusher 62 which is slidably mounted in the body 2 and a handle 4 which is mounted swinging relative to this body to control the back and forth movements of the first pusher 62 inside the body 2.

Le premier poussoir 62 est monté coulissant à l'intérieur d'une première cavité 63 qui s'étend entre une extrémité débouchante 65 sur au moins une face supérieure 7 du corps 2 et un fond 66 opposé à cette extrémité débouchante 65.The first pusher 62 is slidably mounted inside a first cavity 63 which extends between a through end 65 on at least one upper face 7 of the body 2 and a bottom 66 opposite this open end 65.

De préférence, la cavité 63 comprend un épaulement 64 situé en dessous de l'extrémité débouchante 65 et qui s'étend sensiblement transversalement au déplacement du premier poussoir 62 c'est-à-dire, sensiblement perpendiculairement à l'axe X-X.Preferably, the cavity 63 comprises a shoulder 64 located below the open end 65 and which extends substantially transversely to the displacement of the first pusher 62, that is to say, substantially perpendicular to the axis XX.

Dans ce mode de réalisation, le poussoir 62 comporte :

  • une tête 67 réalisée sous forme d'une coiffe comportant un logement cylindrique fermé à son extrémité 68 destinée à être au contact de la jupe 10 de la poignée 4 en formant un fond,
  • un pied 69 réalisé sous forme d'une tige cylindrique de diamètre inférieur au logement de la tête 67 fixée au fond de celui-ci de façon coaxiale par une de ses extrémités,
  • un tronçon intermédiaire 70, de forme générale cylindrique, comportant un logement cylindrique 72 permettant d'accueillir l'extrémité de la coiffe constituant la tête 67 opposée à celle destinée à être au contact de la poignée 4.
In this embodiment, the pusher 62 comprises:
  • a head 67 made in the form of a cap having a cylindrical housing closed at its end 68 intended to be in contact with the skirt 10 of the handle 4 forming a bottom,
  • a foot 69 made in the form of a cylindrical rod of smaller diameter than the housing of the head 67 fixed to the bottom thereof coaxially by one of its ends,
  • an intermediate section 70, of generally cylindrical shape, comprising a cylindrical housing 72 for receiving the end of the cap constituting the head 67 opposite to that intended to be in contact with the handle 4.

Le fond du logement 72 comporte une ouverture centrale 73 d'axe XX de diamètre sensiblement égal à la tige du pied 69 permettant le passage de celui-ci.The bottom of the housing 72 has a central opening 73 of axis XX of diameter substantially equal to the stem of the foot 69 allowing the passage thereof.

Cette disposition garantit que le pied 69 et la tête 67 sont solidaires en mouvement, et peuvent se déplacer en translation selon l'axe XX par rapport au tronçon intermédiaire 70.This arrangement ensures that the foot 69 and the head 67 are integral in movement, and can move in translation along the axis XX with respect to the intermediate section 70.

La tête 67 du premier poussoir 62 vient en butée sous la jupe 10 de la poignée 4 et est commandée entre sa position de repos telle que représentée à la figure 7, et sa position enfoncée telle que représentée à la figure 8, comme cela est bien connu dans l'état de la technique.The head 67 of the first pusher 62 abuts the skirt 10 of the handle 4 and is controlled between its rest position as shown in FIG. figure 7 , and its depressed position as shown in figure 8 as is well known in the state of the art.

Le pied 69 du poussoir 62 est logé dans le fond 66 de la cavité 63 pour permettre la commande d'au moins un premier récepteur extérieur à la télécommande.The foot 69 of the pusher 62 is housed in the bottom 66 of the cavity 63 to allow the control of at least a first external receiver on the remote control.

Selon une caractéristique essentielle de la présente invention, la tête 67 du premier poussoir 62 est en outre mobile vers une position sortie telle que représentée à la figure 9, cette position sortie étant opposée à la position enfoncée par rapport à la position de repos.According to an essential characteristic of the present invention, the head 67 of the first pusher 62 is furthermore movable towards an extended position as represented in FIG. figure 9 , this output position being opposite to the depressed position relative to the rest position.

A cet effet, la télécommande selon la présente invention possède des premiers moyens de rappel élastique 74 constitués par un ressort 74 logé axialement entre le fond du logement 72 et le fond 68 de la coiffe formant la tête 67.For this purpose, the remote control according to the present invention has first elastic return means 74 constituted by a spring 74 housed axially between the bottom of the housing 72 and the bottom 68 of the cap forming the head 67.

Les premiers moyens de rappel élastique 74 sollicitent la tête 67 du premier poussoir 62 vers sa position sortie de manière à ce que ce la tête 67 du poussoir 62 possède un mouvement ascendant qui lui est propre. Au cours de ce mouvement ascendant, la poignée 4 est basculée de manière à dégager la tête 67 du poussoir 62 de sorte que cette tête 67 possède un mouvement ascendant pour suivre la jupe 10 sous l'action des premiers moyens de rappel élastique 74 vers sa position sortie.The first elastic return means 74 bias the head 67 of the first pusher 62 towards its extended position so that the head 67 of the pusher 62 has an upward movement of its own. During this upward movement, the handle 4 is tilted so as to disengage the head 67 from the pusher 62 so that the head 67 has an upward movement to follow the skirt 10 under the action of the first elastic return means 74 towards its exit position.

Le tronçon intermédiaire 70 possède une face supérieure 75 qui délimite une butée haute et une face inférieure 76 qui délimite une butée basse. La face supérieure 75 est tournée en direction de l'épaulement 64 tandis que la face inférieure 76 est tournée en direction du fond 66 de la cavité 63.The intermediate section 70 has an upper face 75 which delimits an upper stop and a lower face 76 which delimits a lower stop. The upper face 75 is turned towards the shoulder 64 while the lower face 76 is turned towards the bottom 66 of the cavity 63.

Ainsi, lors des mouvements de va-et-vient du poussoir 62 à l'intérieur de cette cavité 63, la butée haute 75 est destinée à venir en appui contre l'épaulement 64 comme cela est représenté aux figures 7 et 9 lorsque le poussoir n'est pas en position enfoncée, tandis que la butée basse 76 est destinée à venir en appui contre le fond 66 de cette cavité dans la position ' enfoncée du poussoir comme cela est représenté à la figure 8.Thus, during the back and forth movements of the pusher 62 inside this cavity 63, the upper stop 75 is intended to bear against the shoulder 64 as shown in FIGS. figures 7 and 9 when the pusher is not in the depressed position, while the lower stop 76 is intended to bear against the bottom 66 of this cavity in the 'depressed position of the pusher as shown in FIG. figure 8 .

L'épaulement 64 définit ainsi en quelque sorte la position de repos du poussoir 3.The shoulder 64 thus defines, as it were, the rest position of the pusher 3.

Par ailleurs, selon une autre caractéristique essentielle de l'invention, la télécommande 1 possède des deuxièmes moyens de rappel élastique 77 qui sont logés dans la cavité 63 pour rappeler ce premier poussoir 62 depuis sa position enfoncée telle que représentée à la figure 8, vers sa position de repos telle que représentée à la figure 7.Furthermore, according to another essential characteristic of the invention, the remote control 1 has second elastic return means 77 which are housed in the cavity 63 to recall the first pusher 62 from its depressed position as shown in FIG. figure 8 towards its rest position as shown in figure 7 .

Les deuxièmes moyens de rappel 77 comprennent de préférence une collerette 78 qui est portée par le tronçon intermédiaire 70, au voisinage de la butée haute 75, cette collerette étant tournée en direction du fond 66 de la cavité 63. Les deuxièmes moyens de rappel élastique 77 comprennent également un deuxième ressort de compression 79 qui est interposé entre la collerette 78 et le fond 66 de la cavité 63. Ce ressort de compression 79 est d'un diamètre légèrement supérieur à celui du tronçon intermédiaire 70 de manière à être emmanché sur ce tronçon pour atteindre la collerette 78.The second return means 77 preferably comprise a flange 78 which is carried by the intermediate section 70, in the vicinity of the upper stop 75, this flange being turned towards the bottom 66 of the cavity 63. The second resilient return means 77 also comprise a second compression spring 79 which is interposed between the flange 78 and the bottom 66 of the cavity 63. This compression spring 79 is of a diameter slightly greater than that of the intermediate section 70 so as to be fitted on this section to reach the flange 78.

Comme dans le premier mode de réalisation, afin de commander ledit premier récepteur extérieur, la télécommande 1 comprend des moyens de détection 17 qui permettent de détecter toute position occupée par ce premier poussoir 62 entre ses positions sortie et enfoncée.As in the first embodiment, in order to control said first external receiver, the remote control 1 comprises detection means 17 which make it possible to detect any position occupied by this first pusher 62 between its output and depressed positions.

Le poussoir 62 est en équilibre dans sa position de repos entre l'action exercée par la jupe 10 sur la tête 67 qui à tendance à enfoncer le poussoir 62, et l'action du premier ressort de compression et du deuxième ressort de compression 74 et 79. Dans cette position de repos, la butée haute 75 est en appui contre l'épaulement 64 tandis que la tête 67 est en butée axiale contre le fond du logement 72 du tronçon intermédiaire 70 sous l'action de la poignée 4. Le premier ressort 74 est comprimé.The pusher 62 is in equilibrium in its rest position between the action exerted by the skirt 10 on the head 67 which tends to push the pusher 62, and the action of the first compression spring and the second compression spring 74 and 79. In this rest position, the upper stop 75 bears against the shoulder 64 while the head 67 is in axial abutment against the bottom of the housing 72 of the intermediate section 70 under the action of the handle 4. The first spring 74 is compressed.

Lorsque le poussoir 62 est dans sa position enfoncée telle que représentée à la figure 8, la jupe 10 de la poignée 4 sollicite la tête 67 du poussoir 62 vers le bas de sorte que le tronçon intermédiaire 70 comprime le second ressort de compression 79 jusqu'à ce que ce tronçon intermédiaire 70 soit en butée basse contre le fond 66 de la cavité 63.When the pusher 62 is in its depressed position as shown in FIG. figure 8 , the skirt 10 of the handle 4 urges the head 67 of the pusher 62 downwards so that the intermediate section 70 compresses the second compression spring 79 until this intermediate portion 70 is in a low abutment against the bottom 66 of the cavity 63.

A l'opposé, lorsque la tête du poussoir 62 est dans sa position de sortie telle que représentée à la figure 9, la tête 67 de ce poussoir a été dégagée par la jupe 10 de la poignée 4 de sorte que le tronçon intermédiaire 70 est venue en butée haute contre l'épaulement 64 sous l'action du second ressort de compression 79. De même, le premier ressort de compression 79 se détend. La tête 67 n'est plus en butée axiale contre le fond du logement 72 du tronçon intermédiaire 70 lorsque la tête 67 du poussoir passe de sa position de repos vers sa position sortie.In contrast, when the head of the pusher 62 is in its output position as shown in FIG. figure 9 , the head 67 of this pusher has been disengaged by the skirt 10 of the handle 4 so that the intermediate portion 70 has come into high abutment against the shoulder 64 under the action of the second compression spring 79. Similarly, the first compression spring 79 relaxes. The head 67 is no longer in axial abutment against the bottom of the housing 72 of the intermediate portion 70 when the head 67 of the pusher from its rest position to its extended position.

En fonction de l'inclinaison de la poignée 4, la tête 67 du poussoir 62 occupe toute position entre sa position enfoncée et sa position sortie.Depending on the inclination of the handle 4, the head 67 of the pusher 62 occupies any position between its depressed position and its extended position.

Le pied 69 du poussoir 62 s'étend au-delà du fond 66 de la cavité 63 de manière à traverser ce fond en mouvement de va-et-vient entre ses positions sortie et enfoncée.The foot 69 of the pusher 62 extends beyond the bottom 66 of the cavity 63 so as to cross the bottom reciprocating between its output and depressed positions.

De préférence, comme dans le premier mode de réalisation, les moyens de détection 17 sont du type sans contact mécanique et comprennent par exemple un aimant 40 qui est solidaire en mouvement du pied du poussoir 62 en étant monté à l'intérieur de celui-ci, ainsi qu'un capteur à effet Hall 41 qui est monté dans le corps 2 de la télécommande 1, en regard du déplacement de l'aimant 40 entre les positions enfoncée et sortie du premier poussoir 62. Plus précisément, le capteur à effet Hall 41 est monté dans le corps 2, au-delà du fond 66 de la cavité 63. Ainsi, ce capteur 41 peut être noyé dans une matière telle que de la résine pour le rendre étanche.Preferably, as in the first embodiment, the detection means 17 are of the type without mechanical contact and comprise for example a magnet 40 which is integral in motion of the foot of the pusher 62 being mounted inside thereof , as well as a Hall effect sensor 41 which is mounted in the body 2 of the remote control 1, facing the displacement of the magnet 40 between the depressed and the first output positions. Pusher 62. Specifically, the Hall effect sensor 41 is mounted in the body 2, beyond the bottom 66 of the cavity 63. Thus, this sensor 41 can be embedded in a material such as resin to make it tight .

Afin de permettre l'équilibre de la poignée 4, et de façon similaire au premier mode de réalisation, un deuxième poussoir 80 est implanté dans le corps 2 de la télécommande 1 afin de permettre l'équilibre de la poignée 4. Ce deuxième poussoir 80 est un poussoir passif dans la mesure où il ne permet pas de transmettre un signal de commande à un organe récepteur. Il est implanté dans une cavité 82 ménagée dans le corps 2 à l'opposé de la première cavité 63 par rapport à l'axe de la poignée 4.To allow the balance of the handle 4, and similarly to the first embodiment, a second pusher 80 is implanted in the body 2 of the remote control 1 to allow the balance of the handle 4. This second pusher 80 is a passive pusher in that it does not allow to transmit a control signal to a receiving member. It is implanted in a cavity 82 formed in the body 2 opposite the first cavity 63 with respect to the axis of the handle 4.

Cette cavité 82 est symétrique par rapport à l'axe de la poignée de la première cavité 63. Elle comporte un épaulement 86 symétrique de l'épaulement 64 de la première cavité. Le fond de cette cavité n'est pas percé comme la première cavité 63.This cavity 82 is symmetrical about the axis of the handle of the first cavity 63. It comprises a shoulder 86 symmetrical with the shoulder 64 of the first cavity. The bottom of this cavity is not pierced like the first cavity 63.

Ce deuxième poussoir 80 possède également une tête 83 venant en appui sous la jupe 10 de la poignée 4 et un tronçon 84 solidaire de la tête 83. Dans ce second mode de réalisation, le tronçon 84 du second poussoir 80 est identique au tronçon intermédiaire 70 du premier poussoir, et la tête 83 du second poussoir est identique à la tête 67 du premier poussoir 62, ces deux pièces étant toutefois solidaires, contrairement au premier poussoir 62.This second pusher 80 also has a head 83 bearing under the skirt 10 of the handle 4 and a section 84 secured to the head 83. In this second embodiment, the section 84 of the second pusher 80 is identical to the intermediate section 70. the first pusher, and the head 83 of the second pusher is identical to the head 67 of the first pusher 62, these two parts being however integral, unlike the first pusher 62.

Ce tronçon 84 vient en butée dans le fond de la deuxième cavité 82 et possède une collerette 85 qui vient en butée contre l'épaulement 86 de la cavité 82. Cette cavité 82 s'étend parallèlement à l'axe X-X et entre les niveaux définis par le fond 66 de la première cavité 63 et la position de repos définie par l'épaulement 64 de la première cavité 63.This section 84 abuts in the bottom of the second cavity 82 and has a flange 85 which abuts against the shoulder 86 of the cavity 82. This cavity 82 extends parallel to the axis XX and between the defined levels. by the bottom 66 of the first cavity 63 and the rest position defined by the shoulder 64 of the first cavity 63.

Par ailleurs, ce deuxième poussoir 80 est sollicité par un troisième ressort de compression 86, identique au premier ressort de compression 74, qui est interposé entre la collerette 85 et le fond de cette cavité de manière à solliciter élastiquement ce deuxième poussoir 80 et à provoquer pour l'opérateur, le même effort sur la poignée 4 pour enfoncer le premier poussoir 62 ou le deuxième poussoir 80.Furthermore, this second pusher 80 is biased by a third compression spring 86, identical to the first compression spring 74, which is interposed between the flange 85 and the bottom of this cavity so as to resiliently urge the second pusher 80 and cause for the operator, the same effort on the handle 4 to push the first pusher 62 or the second pusher 80.

Le nombre de pièces constitutives est réduit par rapport au premier mode de réalisation de manière à minimiser le prix de revient et les risques de défaillance technique.The number of component parts is reduced compared to the first embodiment so as to minimize the cost price and the risk of technical failure.

Le montage d'une télécommande selon ce second mode de réalisation est simplifié par l'emploi de pièces identiques entre le premier et le second poussoir.Mounting a remote control according to this second embodiment is simplified by the use of identical parts between the first and the second pusher.

D'autre part, la course du premier ressort de compression est diminuée par rapport au premier mode de réalisation.On the other hand, the stroke of the first compression spring is decreased compared to the first embodiment.

Selon un troisième mode de réalisation représenté sur les figures 10 à 12, l'ensemble des éléments constitutifs est identique au second mode de réalisation, à l'exception du second poussoir 87, qui comporte de la même façon une tête 88 et un tronçon 89. Cependant, la tête et le tronçon ne sont pas solidaires, un ressort de compression 90 étant logé entre la tête 88 et le tronçon 89, de façon similaire au premier poussoir. Dans ce cas, la tête 88 du second poussoir 87 suit la jupe 10 de la poignée 4According to a third embodiment shown on the Figures 10 to 12 all the constituent elements are identical to the second embodiment, with the exception of the second pusher 87, which likewise comprises a head 88 and a section 89. However, the head and the section are not integral, a compression spring 90 being housed between the head 88 and the section 89, similarly to the first pusher. In this case, the head 88 of the second pusher 87 follows the skirt 10 of the handle 4

Cette disposition permet de renforcer la symétrie du montage, évitant ainsi les erreurs de montage, et garantit de plus un couple dans la poignée symétrique entre les positions d'enfoncement et de sortie.This arrangement makes it possible to reinforce the symmetry of the assembly, thus avoiding assembly errors, and moreover guarantees a torque in the symmetrical handle between the driving and output positions.

Bien entendu, l'invention n'est pas limitée aux exemples décrits ci-dessus et diverses modifications peuvent y être apportées sans sortir du cadre des revendications.Of course, the invention is not limited to the examples described above and various modifications can be made without departing from the scope of the claims.
