Definitions
- the invention relates to a data input device being made by means of a switch actuated by a rod.
- the invention finds particular utility for a rod that can be pulled or pushed around an equilibrium position.
- the two movements of the rod, pull and push allow each to enter a datum.
- the switch is usually placed at one end of the rod.
- An operator pulls or pushes the rod, causing the operation of the corresponding switch.
- the rod may also allow the operation of a rotary encoder around the axis of translation of the rod.
- the data from the rotary encoder can be optically encoded in an electronic part of the device.
- a tactile sensation whose main function is to ensure that the electrical release of the switch is ensured after the passage of a peak effort.
- the deflection can be important, for example greater than one millimeter.
- Such devices are found in the aeronautical industry and more particularly in aircraft dashboards. The safety of the flight of the aircraft may depend on the data input made by means of the device. This is why many manufacturers impose severe constraints in the tactile feedback that a pilot must feel when operating the device.
- a ball cooperating with the rod More specifically, on the rod is formed a cam comprising an inclined pan followed by a plane parallel to the axis of movement of the rod.
- the ball can move perpendicular to the axis of movement of the rod by relying on the cam by means of a spring.
- the stem At rest, the stem is in a position of equilibrium. This position is maintained by a return spring capable of compressing along the axis of movement of the rod. In this equilibrium position, the ball is in contact with the cam at the bottom of the inclined face.
- the ball rises on the inclined pan by compressing its spring until reaching the parallel plane.
- the force exerted by the ball on the cam is added to that exerted by the return spring of the rod.
- the force added by the ball brought back to the axis
- the displacement of the rod is practically nil, with the friction close, and the only effort that the operator must overcome is that generated by the return spring of the rod.
- the ball is in contact with the inclined pan, it exerts an axial component of force on the rod. This axial component, added to the force generated by the return spring, forms a peak effort that the operator must overcome by operating the rod.
- the accuracy of these systems depends in particular on the diameter of the ball and its position on the inclined pan at the equilibrium position, which imposes tight tolerances of realization.
- the peak of effort depends on the diameter of the ball, the force exerted by the spring of the ball and the slope of the inclined face.
- the slope of the return curve of the rod depends on the stiffness of the return spring and the friction force of the ball on the cam.
- the subject of the invention is a data input device according to claim 1.
- the slope is defined as a surface angularly offset from the direction of movement of the rod.
- the orientation of the angle is such that the force exerted by the circular element on the rod opposes the displacement of the rod from its equilibrium position.
- the slope is also defined as a surface angularly offset from the direction of movement of the rod.
- the orientation of the angle of the slope is reversed relative to that of the slope so that the force exerted by the circular element on the rod tends to facilitate the displacement of the rod from its position. balance.
- the invention makes it possible to ensure that the movement of the rod can not be stopped physically before the switch is triggered.
- a data input device comprising a switch allowing the input of the data, a rod movable in translation relative to a housing and a return spring allowing the rod to return to a equilibrium position where the rod is not maneuvered.
- the displacement in translation of the rod makes it possible to manipulate the switch.
- the invention can be implemented in a rotator where a rotational movement of the rod allows to operate the switch.
- the rod is rotatable relative to the housing and the rotation of the rod makes it possible to enter a datum represented by the angular position of the rod.
- the switch will not be described.
- the rod serves as an intermediary between the operator and the moving part of the switch.
- the switch is for example a push button operated in translation.
- the switch may also be an optical encoder comprising a mask integral with the rod and movable between a transmitter and a detection cell, the transmitter and the detection cell being integral with the housing.
- the use of an optical encoder the advantage of not producing stress on the rod. The only forces between the housing and the stem come from the different constituent elements of the invention.
- the rod is secured to the moving part of the push button and an operator exerts a force on the rod. This effort is transmitted to the mobile part.
- the invention allows a net movement of the moving part and thus improves the reliability of the data input made by the operation of the switch.
- the device comprises means for modulating a force exerted by the return spring in order to define a peak force at a point of the stroke of the rod beyond which the switch is maneuvered;
- the figure 1 allows to illustrate this peak of effort. More specifically, the figure 1 represents an example of curve 10 defining the force FO to be applied on the rod, ordinate, as a function of displacement or stroke D of the latter carried on the abscissa.
- the electrical contact of the switch must be made after the peak of effort 11 and before the end of the race.
- the part of the race where the switch is operated is represented by dimension 19.
- the figure 2 schematically represents the forces exerted on the rod when it is in equilibrium position.
- the device comprises a cam 20 integral with the rod 21 and a circular element 22 capable of moving substantially perpendicular to the displacement of the rod 21.
- the displacement of the rod 21 is in translation along an axis 23.
- the element circular 22 is held in abutment against the cam 20 by means of a spring 24.
- the cam 20 comprises a slope 25, a high point 26 and a slope 27 on which relies successively the circular element 22 when the rod 21 is operated from its equilibrium position to a position where the switch is operated.
- the circular element 22 may be rigid: a spherical ball or a cylinder whose axis is perpendicular to the plane of the figure 2 .
- a cylindrical shape makes it possible to better distribute the force exerted by the circular element 22 against the cam 20 and thus to reduce the wear on the cam 20 and the circular element 22.
- the circular element and the resilient means holding the circular element in pressure against the cam 20 can be made by means of a single mechanical part such as an elastic ring.
- the circular outer shape of the ring is in contact with the cam 20 and the elasticity of the ring makes it possible to keep it bearing against the cam 20 throughout the movement of the rod 21.
- the device also comprises a return spring 29 opposing the displacement of the rod 21 and can therefore be compressed along the axis 23.
- a return spring 29 opposing the displacement of the rod 21 and can therefore be compressed along the axis 23. In the equilibrium position, the rod is in abutment against the housing 28, the return spring 29 is compressed so as to hold the rod 21 against the housing 28 and the circular element 22 bears on the slope 25.
- the radial component can also be cashed by a second assembly formed of a cam, a circular element and a spring.
- This second set is arranged in the data input device symmetrically to the first assembly formed of the cam 20, the circular element 22 and the spring 24 shown on the drawing. figure 2 .
- the symmetry of the two sets is made with respect to the axis 23.
- the sum of the axial and radial components exerted by the circular element 22 on the rod 21 is substantially perpendicular to a plane tangential to the cam 20 at the point of contact between the circular element 22 and the cam 20. In this decomposition we do not take into account the friction that could be taken into account in a finer modeling.
- the circular element 22 reaches the high point 26.
- This high point is the junction between the slope 25 and the slope 27.
- the effort FC changes direction to move towards the right of the figure 2 .
- the figure 3 represents the position of the rod 21 after the passage of the rod 21 around the high point 26.
- the depth of displacement 14 corresponds to the passage of the circular element around the high point 26.
- the change of direction of the effort FC allows The recess may appear in the curve 10 between the force peak 11 and the minimum 13. This recess corresponds to the passage of the circular element 22 at the level of the high point 26.
- the forces FC and FR evolve linearly as a function of the respective compression of the springs 24 and 29, which corresponds to the linear portion 16 of the curve 10.
- the slope of the linear part 16 can be adapted by changing the inclination of the slope 27 and thus ensure that the effort value 17 is lower, or even significantly lower than that of the effort peak 11 while remaining positive to allow the return of the rod 21 to its equilibrium position if the effort exerted by the operator FO is released.
- the dimensions of the cam 20 are defined such that an effort FO exerted on the rod 21 throughout a portion 19 of the stroke of the rod 21, part where the switch is operated, is less than the effort peak 11.
- the depth of displacement 14 is substantially equal to the radius of the circular element 22 multiplied by the sine of the angle of the slope 25 with respect to the axis 23.
- the depth of the displacement is elongated by the radius of the circular element 22 multiplied by the sine of the angle of the slope 27 relative to the axis 23. It is thus possible for the same depth of displacement 14 reduce the radius of the circular element 22, which reduces the size of the device.
- the presence of the slope 27 allows a greater hollow force 15 due to the reversal of the FC effort. Without slope 27, there is simply a cancellation of the force FC when the circular element 22 reaches the flat surface parallel to the axis 23. It is thus possible for a hollow of the given force 15 to reduce the force exerted. by the spring 24 by implementing the invention. This reduction in effort makes it possible to reduce the wear on the cam 20 and the circular element 22. It is also possible to use softer and less expensive materials. In one embodiment of the invention, it has for example been possible to replace a metal cam 20 with a cam 20 made of plastic material while maintaining the same service life of the device, for example a lifetime measured in number of maneuvers.
- the circular element 22 rests on the cam 20 at a junction 30 between the slope 25 and the high point 26.
- the force FC is oriented in the opposite direction to the effort FO, from where a major effort to overcome by the operator to take off the rod 21 of its abutment against the housing 28.
- the force FC decreases. This makes it possible to reduce strongly, or even to suppress, the first part 12 of the displacement of the rod 21.
- he is required to exert an almost equal effort at the peak of effort 11. This causes a depression of the rod 21 coinciding almost with the beginning of its movement and thus an improvement in the reliability of the operation of the switch.
- the device may include a second switch.
- the means for modulating the effort make it possible to create a second peak of effort in the stroke of the rod beyond which the second switch is operated.
- This variant is explained using the Figures 4 to 4f .
- the device comprises only one circular element 22 that can move along a cam 40 comprising two slopes 25a and 25b, two high points 26a and 26b and two against slopes 27a and 27b on which the element relies successively circular 22 when the rod 21 is operated from its equilibrium position.
- the zones 25a, 26a and 27a of the cam 40 are similar to the zones 25, 26 and 27 already described and the zones 25b, 26b and 27b serve to support the circular element 22 when the rod 21 moves towards a position where the second switch is operated.
- the figure 4f represents an enlarged view of the cam 40 alone.
- the two slopes, 25a and 25b, the two high points 26a and 26b and the two against slopes 27a and 27b are respectively symmetrical with respect to the same point of the cam 40, located between the two slopes 25a and 25b.
- the equilibrium position of the rod 21 is obtained when the circular element 22 is simultaneously supported on the two slopes 25a and 25b. It is not necessarily necessary to provide an abutment against the housing 28 to maintain the rod 21 against its equilibrium position.
- the figure 4 represents a curve of the force FO, ordinate, expressed in newtons and exerted on the rod 21 by the operator as a function of the displacement of the rod 21 on the abscissa and expressed in millimeters.
- the curve illustrates the movement of the rod 21 in only one direction from the equilibrium position.
- the circular element 22 bears on the slope 25a and is slightly off the slope 25b.
- the force FO has a value of the order of 9.5N corresponding to the effort peak 11.
- the circular element 22 bears on the cam 40 at a junction 30a between the slope 25a and the high point 26a.
- the curve of the figure 4 decreases to reach a value of the order of 7.5N at the point where the circular element 22 completely leaves the slope 25a to follow the high point 26a.
- This zone of the cam 40 formed by the high point 26a is for example a small surface substantially parallel to the axis 23 of displacement of the rod 21.
- the circular element 22 bears on the cam 40 at a junction 41a between the high point 26a and the slope 27a.
- the force FC increases in absolute value from a zero value, when the circular element 22 bears on the high point 26a, up to a maximum value, when the circular element 22 completely leaves the necessary point 26a. to follow the slope 27a.
- the effort FO then has a value of the order of 6.5N. Beyond this point, the circular element 22 follows the slope 27a and the curve of the figure 4 is linear and increasing as in part 16 of curve 10.
- the origin of the displacements of the rod 21 is the equilibrium position of the rod 21 and the curve represented figure 4 allows to deduce a symmetrical curve when the circular element 22 follows the zones 25b, 26b and 27b of the ramp when the rod 21 is moved by the operator in the direction of the negative abscissa.
- the peak force 11 is here obtained from the equilibrium position, because the circular element 22 bears against the junction 30a.
- the figure 5 represents a graph obtained for a device with two switches that can be maneuvered in translation around a position of balance defined by a single return spring that can be compressed or stretched.
- This equilibrium position can also be defined by means of two pre-loaded and antagonistic springs. Both springs bear on both the housing 28 and the rod 21. At the equilibrium position the forces exerted by each of the springs are equal in absolute value and opposite in direction.
- This graph defines the curve 10 as for the figures 1 and 4 with the abscissa the stroke of the rod 21 and ordinate the force FO to be applied to the rod 21 to move it.
- Curve 10 is symmetrical with respect to the origin of the reference of this graph.
- a curve 50 representing the return force FR is a straight line passing through the origin of the marker. The curve is obtained either with a return spring or with two opposing springs whose stiffness or stiffness are constant.
- This embodiment makes it possible to define two peaks of forces 11, one negative and the other positive, both placed on the vertical axis as for the figure 4 but has several disadvantages.
- the minimums 13 of the first and third quadrants are close to the horizontal axis of the graph.
- the wear of the device can degrade the shape of the curve 10 and if a minimum 13 was to pass on the other side of the horizontal axis, the rod 21 would no longer return to its equilibrium position.
- the equilibrium position is defined when the circular element 22 is in simultaneous support on the two slopes 25a and 25b, it is necessary to adjust the setting of the spring or return springs so that at this position of balance the curve 50 passes well by the origin of the marker. In other words, at the equilibrium position, the spring or springs must not apply any force on the rod 21.
- the figure 6 illustrates a solution to these disadvantages.
- the device comprises two return spring 60 and 61.
- the two return springs 60 and 61 are arranged in such a way that only one of the return springs 60 or 61 is compressed when the rod 21 leaves its equilibrium position. another return spring 60 or 61 remaining in the state of the equilibrium position.
- the two springs 60 and 61 operate independently of one another.
- the device comprises a support piece 62 that can move relative to the rod 21 and relative to the housing 28. In the equilibrium position, the support piece 62 is supported against the housing 28 and against the rod 21.
- the first return spring 60 bears between the housing 28 and the support piece 62 and the second return spring 61 bears between the rod 21 and the support piece 62. Both springs 60 and 61 exert a force on the support piece 62 in the same direction.
- the equilibrium position does not depend on the tension of the return springs 60 and 61.
- the equilibrium position is defined by the support of rigid mechanical parts against each other, namely the support piece 62 on the against the rod 21 and against the housing 28.
- the displacement of the rod 21 is in translation along the axis 23 to manipulate the two switches.
- the support piece 62 is a piece of revolution in the form of a washer traversed by the rod 21 and can move in translation along the rod 21 in a bore 63 of axis 23 of the housing 28. At the position of equilibrium, the support piece 62 bears against a bottom 64 of the bore 63. In this same position, the support piece 62 bears against a shoulder 65 of the rod 21.
- the two springs 60 and 61 are helical. They are mounted concentrically around the axis 23.
- the bore 63 is partially closed by a cover 66 on which the spring 60 bears by a first of its ends 60a, possibly via a washer 67.
- a second end 60b of the spring 60 bears against the support piece 62.
- the rod 21 passes through the washer 67 and the cover 66.
- the spring 61 bears against a first end 61a against a washer 68
- a second end 61b of the spring 61 bears against the bearing piece 62.
- the washer 68 is secured to the rod 21 by means of a circlip 69 disposed in a groove 70 of the rod 21.
- the support piece 62 may comprise a tubular extension 71 to limit the displacement of the support piece 62 in the bore 63.
- the extension 71 can abut against the washer 67 to limit the displacement of the rod 21 in the direction "push" P.
- the support piece 62 rest against the shoulder 65.
- the washers 62 and 68 both follow the movement of the rod 21.
- the spring 61 does not deform when the operator pushes on the rod 21.
- the cam 40 secured to the rod 21, the circular element 22 and the spring 24 both sliding in a radial housing 75 of the cover 66 are also shown.
- the spring 24 disappears and only the elastic ring is located in the housing 75.
- the precise definition of the equilibrium position achieved by means of the two return springs 60 and 61 is complementary to the means for modulating the force of the return springs 60 and 61, means implementing the cam 40 and the element circular 22. It is of course possible to implement the precise definition of the equilibrium position without means for modulating the force of the return springs 60 and 61.
- the figure 7 represents the axial components of the various efforts involved in the exemplary embodiment defined in the figure 6 .
- the curve 50 representing the return force FR as a function of the stroke of the rod 21, is linear in each of the quadrants where it is present. The linearity is due to the stiffness of each spring 60 and 61.
- the two springs 60 and 61 have the same stiffness and the slope of the curve 50 is the same for both quadrants. It is of course possible to use springs 60 and 61 having different stiffnesses which would lead to different slopes in each of the quadrants where the curve 50 is present.
- curve 50 of the figure 7 includes a jump at the vertical axis.
- the y-intercept has a positive value 80.
- the ordinate at the origin has a negative value 81.
- the two ordinates at the origin 80 and 81 represent the calibration or preload of the return spring 60 or 61 corresponding. This is a force that the return springs 60 and 61 exert when the device is at its equilibrium position. This calibration can be equal or different for the two return springs 60 and 61. This calibration makes it possible to increase the values of the stress peaks 11 and the minimums 13 of each quadrant and more generally to shift the curves 10.
- a curve 82 representing the variation of the force FC as a function of the stroke is also shown.
- the curve 82 corresponds to the evolution of the effort FC explained by means of the Figures 2 and 3 .
- the value of the force FC is positive.
- the effort FC is zero and when the circular element 22 is in contact with the slope 27, the value of the effort FC is negative.
- a curve 83 shows the evolution of a friction force FF of the circular element 22 during its displacement along the cam 40 away from the balance position.
- the value of the force FF has the same sign the force FR when the cam 40 moves away from the equilibrium position.
- the sign of the value of the force FF is reversed when the cam returns to the equilibrium position. To avoid overloading the figure 7 only the positive FF friction force has been shown.
- the effort FO that the operator must exert on the rod 21 to move it is equal to the sum of the forces FR, FC and FF.
- the curve 10 shown is the force FO when the rod moves away from the equilibrium position. Because of the negative sign of the friction force FF, the curve 10, not shown here, would approach the horizontal axis when the rod 21 returns to the equilibrium position.
- the setting of the return springs 60 and 61 may take into account the friction force FF to prevent the minimums 13 have values too low, which could cause the non-return of the rod to the equilibrium position.

Description
L'invention concerne un dispositif d'entrée de donnée se faisant au moyen d'un interrupteur manoeuvré par une tige.The invention relates to a data input device being made by means of a switch actuated by a rod.
L'invention trouve une utilité particulière pour une tige que l'on peut tirer ou pousser autour d'une position d'équilibre. Les deux déplacements de la tige, tirer et pousser, permettent chacun d'entrer une donnée. Pour chaque sens de déplacement de la tige, l'interrupteur est généralement placé à une extrémité de la tige. Un opérateur tire ou pousse la tige, entraînant la manoeuvre de l'interrupteur correspondant. La tige peut également permettre la manoeuvre d'un codeur rotatif autour de l'axe de translation de la tige. Les données issues du codeur rotatif peuvent être codées optiquement dans une partie électronique du dispositif.The invention finds particular utility for a rod that can be pulled or pushed around an equilibrium position. The two movements of the rod, pull and push, allow each to enter a datum. For each direction of movement of the rod, the switch is usually placed at one end of the rod. An operator pulls or pushes the rod, causing the operation of the corresponding switch. The rod may also allow the operation of a rotary encoder around the axis of translation of the rod. The data from the rotary encoder can be optically encoded in an electronic part of the device.
Dans un tel dispositif, on cherche à générer une sensation tactile qui a pour fonction principale de garantir que le déclenchement électrique de l'interrupteur est assuré après le passage d'un pic d'effort. Pour une bonne sensation tactile, il est nécessaire que le débattement puisse être important, par exemple supérieur à un millimètre. On trouve de tels dispositifs dans l'industrie aéronautique et plus particulièrement dans les planches de bord d'aéronefs. La sécurité du vol de l'aéronef peut dépendre de l'entrée de donnée effectuée au moyen du dispositif. C'est pourquoi de nombreux constructeurs imposent des contraintes sévères dans le retour tactile qu'un pilote doit ressentir lors de la manoeuvre du dispositif.In such a device, it seeks to generate a tactile sensation whose main function is to ensure that the electrical release of the switch is ensured after the passage of a peak effort. For a good tactile sensation, it is necessary that the deflection can be important, for example greater than one millimeter. Such devices are found in the aeronautical industry and more particularly in aircraft dashboards. The safety of the flight of the aircraft may depend on the data input made by means of the device. This is why many manufacturers impose severe constraints in the tactile feedback that a pilot must feel when operating the device.
Pour ce faire le demandeur a tenté de réaliser cette fonction au moyen d'une bille coopérant avec la tige. Plus précisément, sur la tige est formée une came comprenant un pan incliné suivi d'un plan parallèle à l'axe de déplacement de la tige. La bille peut se déplacer perpendiculairement à l'axe de déplacement de la tige en s'appuyant sur la came au moyen d'un ressort. Au repos, la tige est dans une position d'équilibre. Cette position est maintenue par un ressort de rappel susceptible de se comprimer suivant l'axe de déplacement de la tige. Dans cette position d'équilibre, la bille est en contact avec la came au bas du pan incliné. Lorsque la tige est actionnée par un opérateur, la bille monte sur le pan incliné en comprimant son ressort jusqu'à atteindre le plan parallèle. L'effort exercé par la bille sur la came s'ajoute à celui exercé par le ressort de rappel de la tige. Lorsque la bille est en contact avec le plan parallèle, l'effort ajouté par la bille, ramené sur l'axe de déplacement de la tige est pratiquement nul, au frottement près, et le seul effort que doit vaincre l'opérateur est celui généré par le ressort de rappel de la tige. Par contre, lorsque la bille est en contact avec le pan incliné, elle exerce une composante axiale d'effort sur la tige. Cette composante axiale, ajoutée à l'effort généré par le ressort de rappel, forme un pic d'effort que l'opérateur doit vaincre en actionnant la tige.To do this the applicant has attempted to achieve this function by means of a ball cooperating with the rod. More specifically, on the rod is formed a cam comprising an inclined pan followed by a plane parallel to the axis of movement of the rod. The ball can move perpendicular to the axis of movement of the rod by relying on the cam by means of a spring. At rest, the stem is in a position of equilibrium. This position is maintained by a return spring capable of compressing along the axis of movement of the rod. In this equilibrium position, the ball is in contact with the cam at the bottom of the inclined face. When the rod is actuated by an operator, the ball rises on the inclined pan by compressing its spring until reaching the parallel plane. The force exerted by the ball on the cam is added to that exerted by the return spring of the rod. When the ball is in contact with the parallel plane, the force added by the ball, brought back to the axis The displacement of the rod is practically nil, with the friction close, and the only effort that the operator must overcome is that generated by the return spring of the rod. By cons, when the ball is in contact with the inclined pan, it exerts an axial component of force on the rod. This axial component, added to the force generated by the return spring, forms a peak effort that the operator must overcome by operating the rod.
La précision de ces systèmes dépend notamment du diamètre de la bille et de sa position sur le pan incliné à la position d'équilibre, ce qui impose des tolérances serrées de réalisation. Le pic d'effort dépend du diamètre de la bille, de l'effort exercé par le ressort de la bille et de la pente du pan incliné. Dans une courbe donnant l'effort exercé sur la tige en fonction du déplacement de celle-ci, la pente de la courbe de rappel de la tige dépend de la raideur du ressort de rappel et de l'effort de frottement de la bille sur la came.The accuracy of these systems depends in particular on the diameter of the ball and its position on the inclined pan at the equilibrium position, which imposes tight tolerances of realization. The peak of effort depends on the diameter of the ball, the force exerted by the spring of the ball and the slope of the inclined face. In a curve giving the force exerted on the rod as a function of the displacement thereof, the slope of the return curve of the rod depends on the stiffness of the return spring and the friction force of the ball on the cam.
Ces systèmes nécessitent des diamètres de bille, un effort de compression des billes et une longueur et hauteur de la pente du clic importants pour avoir une course mécanique et un creux d'effort importants pour des grands débattements avec une sensation tactile identifiable. Les efforts de compression importants des billes nécessitent des matériaux durs superficiellement pour tenir l'usure des manoeuvres répétées.These systems require ball diameters, a compression force of the balls and a length and height of the click slope important to have a mechanical stroke and a large effort cavity for large deflections with an identifiable tactile sensation. The large compression forces of the balls require superficially hard materials to hold the wear of repeated maneuvers.
De plus, après de nombreuses manoeuvres l'usure de la came et de la bille altère la sensation tactile en augmentant la profondeur de déplacement entre l'effort maximal au pic et l'effort minimal qui suit. Le document "
A cet effet, l'invention a pour objet un dispositif d'entrée de donnée selon la revendication 1. Par convention, la pente est définie comme une surface angulairement décalée par rapport à la direction du déplacement de la tige. L'orientation de l'angle est telle que l'effort exercée par l'élément circulaire sur la tige s'oppose au déplacement de la tige depuis sa position d'équilibre. La contre pente est également définie comme une surface angulairement décalée par rapport à la direction du déplacement de la tige. Par contre, l'orientation de l'angle de la contre pente est inversée par rapport à celui de la pente de telle sorte que l'effort exercée par l'élément circulaire sur la tige tend à faciliter le déplacement de la tige depuis sa position d'équilibre.For this purpose, the subject of the invention is a data input device according to claim 1. By convention, the slope is defined as a surface angularly offset from the direction of movement of the rod. The orientation of the angle is such that the force exerted by the circular element on the rod opposes the displacement of the rod from its equilibrium position. The slope is also defined as a surface angularly offset from the direction of movement of the rod. On the other hand, the orientation of the angle of the slope is reversed relative to that of the slope so that the force exerted by the circular element on the rod tends to facilitate the displacement of the rod from its position. balance.
L'invention permet de s'assurer que le déplacement de la tige ne peut pas être arrêté physiquement avant le déclenchement de l'interrupteur.The invention makes it possible to ensure that the movement of the rod can not be stopped physically before the switch is triggered.

La description qui suit est faite en rapport à un dispositif d'entrée de donnée comprenant un interrupteur permettant l'entrée de la donnée, une tige mobile en translation par rapport à un boitier et un ressort de rappel permettant à la tige de revenir à une position d'équilibre où la tige n'est pas manoeuvrée. Le déplacement en translation de la tige permet de manoeuvrer l'interrupteur. Il est bien entendu que l'invention peut être mise en oeuvre dans un rotacteur où un déplacement en rotation de la tige permet de manoeuvrer l'interrupteur. Autrement dit, la tige est mobile en rotation par rapport au boitier et la rotation de la tige permet d'entrer une donnée représentée par la position angulaire de la tige.The following description is made in relation to a data input device comprising a switch allowing the input of the data, a rod movable in translation relative to a housing and a return spring allowing the rod to return to a equilibrium position where the rod is not maneuvered. The displacement in translation of the rod makes it possible to manipulate the switch. It is understood that the invention can be implemented in a rotator where a rotational movement of the rod allows to operate the switch. In other words, the rod is rotatable relative to the housing and the rotation of the rod makes it possible to enter a datum represented by the angular position of the rod.
Par la suite, l'interrupteur ne sera pas décrit. On peut mettre en oeuvre tout type d'interrupteur manoeuvré par le mouvement d'une partie mobile. La tige sert d'intermédiaire entre l'opérateur et la partie mobile de l'interrupteur. L'interrupteur est par exemple un bouton poussoir manoeuvré en translation. L'interrupteur peut également être un codeur optique comprenant un masque solidaire de la tige et pouvant se déplacer entre un émetteur et une cellule de détection, l'émetteur et la cellule de détection étant solidaires du boîtier. L'utilisation d'un codeur optique présente l'avantage de ne pas produire d'effort sur la tige. Les seuls efforts entre boîtier et tige sont issus des différents éléments constitutifs de l'invention.Subsequently, the switch will not be described. One can implement any type of switch operated by the movement of a moving part. The rod serves as an intermediary between the operator and the moving part of the switch. The switch is for example a push button operated in translation. The switch may also be an optical encoder comprising a mask integral with the rod and movable between a transmitter and a detection cell, the transmitter and the detection cell being integral with the housing. The use of an optical encoder the advantage of not producing stress on the rod. The only forces between the housing and the stem come from the different constituent elements of the invention.
La tige est solidaire de la partie mobile du bouton poussoir et un opérateur exerce un effort sur la tige. Cet effort est transmis à la partie mobile. L'invention permet un mouvement net de la partie mobile et permet donc d'améliorer la fiabilité de l'entrée de donnée réalisée par la manoeuvre de l'interrupteur.The rod is secured to the moving part of the push button and an operator exerts a force on the rod. This effort is transmitted to the mobile part. The invention allows a net movement of the moving part and thus improves the reliability of the data input made by the operation of the switch.
Le dispositif comprend des moyens pour moduler un effort exercé par le ressort de rappel afin de définir un pic d'effort à un point de la course de la tige au-delà duquel l'interrupteur est manoeuvré ; La
A l'origine du repère aucun effort n'est exercé sur la tige et elle est dans une position d'équilibre. A partir de cette position, pour entamer le déplacement de la tige, l'effort doit croitre rapidement jusqu'à atteindre un maximum 11 appelé pic par la suite. Cette première partie du déplacement de la tige porte le repère 12. Au-delà du pic 11, l'effort pour poursuivre le déplacement de la tige décroit pour atteindre un minimum 13. Entre le pic 11 et le minimum 13, la partie du déplacement s'y rapportant est appelée profondeur du déplacement 14. La différence entre la valeur du pic et celle du minimum est appelée creux de l'effort 15. Au delà de la profondeur de déplacement 14, la courbe 10 entre dans une partie 16 linéaire et croissante jusqu'à atteindre une valeur d'effort 17 obtenue en fin de course de la tige. On peut prévoir une butée pour arrêter la tige. La totalité de la course de la tige est représenté par une cote 18.At the origin of the marker, no effort is exerted on the rod and it is in a position of equilibrium. From this position, to begin the movement of the rod, the effort must grow rapidly to reach a maximum 11 called peak thereafter. This first part of the displacement of the rod carries the
Le contact électrique de l'interrupteur doit se faire après le pic d'effort 11 et avant la fin de la course. La partie de la course où l'interrupteur est manoeuvré est représenté par la cote 19. Pour s'assurer que l'interrupteur est bien manoeuvré lors de la manoeuvre de la tige par un opérateur, il est important que la valeur d'effort 17 soit inférieure à celle du pic d'effort 11. On verra par la suite comment grâce à l'invention, on peut régler la valeur d'effort 17.The electrical contact of the switch must be made after the peak of
La
La came 20 comprend une pente 25, un point haut 26 et une contre pente 27 sur lesquels s'appuie successivement l'élément circulaire 22 lorsque la tige 21 est manoeuvrée depuis sa position d'équilibre vers une position où l'interrupteur est manoeuvré. L'élément circulaire 22 peut être rigide : une bille sphérique ou un cylindre dont l'axe est perpendiculaire au plan de la
Le dispositif comprend également un ressort de rappel 29 s'opposant au déplacement de la tige 21 et pouvant donc se comprimer suivant l'axe 23. Dans la position d'équilibre, la tige est en butée contre le boitier 28, le ressort de rappel 29 est comprimé de façon à maintenir la tige 21 contre le boitier 28 et l'élément circulaire 22 est en appui sur la pente 25.The device also comprises a
Pour décoller la tige 21 du boitier 28, un opérateur exerce sur la tige 21 un effort FO dirigé vers la gauche de la
Les forces FR et FC sont orientées dans le même sens vers la droite de la
A la fin de la première partie 12 du déplacement de la tige 21 vers la gauche de la
Lorsque l'élément circulaire 22 est en appui sur la contre pente 27, les efforts FC et FR évoluent linéairement en fonction de la compression respective des ressorts 24 et 29 ce qui correspond à la partie linéaire 16 de la courbe 10. La pente de la partie linéaire 16 peut être adaptée en modifiant l'inclinaison de la contre pente 27 et ainsi s'assurer que la valeur d'effort 17 soit inférieure, voire nettement inférieure à celle du pic d'effort 11 tout en restant positive afin de permettre le retour de la tige 21 vers sa position d'équilibre si l'effort FO exercé par l'opérateur est relâché.When the
De façon plus générale, les dimensions de la came 20 sont définis de telles sorte qu'un effort FO exercé sur la tige 21 tout au long d'une partie 19 de la course de la tige 21, partie où l'interrupteur est manoeuvré, est inférieur au pic d'effort 11.More generally, the dimensions of the
En l'absence de contre pente 27, c'est-à-dire lorsque la pente est suivie d'une surface plane parallèle à l'axe 23, la profondeur du déplacement 14 est sensiblement égale au rayon de l'élément circulaire 22 multiplié par le sinus de l'angle de la pente 25 par rapport à l'axe 23. En mettant en oeuvre l'invention, la profondeur du déplacement est allongée du rayon de l'élément circulaire 22 multiplié par le sinus de l'angle de la contre pente 27 par rapport à l'axe 23. On peut ainsi pour une même profondeur du déplacement 14 réduire le rayon de l'élément circulaire 22, ce qui permet de réduire l'encombrement du dispositif.In the absence of
De plus, la présence de la contre pente 27 permet un plus grand creux de l'effort 15 du fait de l'inversion de sens de l'effort FC. Sans contre pente 27, on a simplement une annulation de l'effort FC lorsque l'élément circulaire 22 parvient sur la surface plane parallèle à l'axe 23. On peut ainsi pour un creux de l'effort 15 donné réduire l'effort exercé par le ressort 24 en mettant en oeuvre l'invention. Cette réduction d'effort permet de réduire l'usure de la came 20 et de l'élément circulaire 22. On peut également utiliser des matériaux plus tendres et moins onéreux. Dans une réalisation de l'invention, on a par exemple pu remplacer une came 20 métallique par une came 20 en matériau plastique tout en conservant une même durée de vie du dispositif, durée de vie par exemple mesurée en nombre de manoeuvre.In addition, the presence of the
Avantageusement, lorsque la tige 21 est dans sa position d'équilibre, l'élément circulaire 22 s'appuie sur la came 20 au niveau d'une jonction 30 entre la pente 25 et le point haut 26. Ainsi, à la position d'équilibre, l'effort FC est orienté en sens opposé à l'effort FO, d'où un effort important à vaincre par l'opérateur pour décoller la tige 21 de sa butée contre le boîtier 28. Ensuite, dès le début de la course de la tige 21, l'effort FC diminue. Cela permet de réduire fortement, voir de supprimer la première partie 12 du déplacement de la tige 21. Ainsi pour que l'opérateur ressente un déplacement de la tige 21, il est tenu d'exercer un effort quasiment égal au pic d'effort 11. Ceci entraine un enfoncement de la tige 21 coïncidant quasiment avec le début de son déplacement et donc une amélioration de la fiabilité de la manoeuvre de l'interrupteur.Advantageously, when the
Le dispositif peut comprendre un second interrupteur. Les moyens pour moduler l'effort permettent de créer un second pic d'effort dans la course de la tige au-delà duquel le second interrupteur est manoeuvré. Cette variante est expliquée à l'aide des
Avantageusement, les deux pentes, 25a et 25b, les deux points hauts 26a et 26b et les deux contre pentes 27a et 27b sont respectivement symétriques par rapport au même point de la came 40, point situé entre les deux pentes 25a et 25b. La position d'équilibre de la tige 21 est obtenue lorsque l'élément circulaire 22 est en appui simultané sur les deux pentes 25a et 25b. Il n'est pas forcément nécessaire de prévoir une butée contre le boitier 28 pour maintenir la tige 21 contre sa position d'équilibre.Advantageously, the two slopes, 25a and 25b, the two

La position d'équilibre ne dépend pas de la tension des ressorts de rappel 60 et 61. La position d'équilibre est définie par l'appui de pièces mécaniques rigides les unes contre les autres, à savoir la pièce d'appui 62 à la fois contre la tige 21 et contre le boîtier 28.The equilibrium position does not depend on the tension of the return springs 60 and 61. The equilibrium position is defined by the support of rigid mechanical parts against each other, namely the
Dans l'exemple représenté, le déplacement de la tige 21 se fait en translation le long de l'axe 23 pour manoeuvrer les deux interrupteurs. La pièce d'appui 62 est une pièce de révolution ayant la forme d'une rondelle traversée par la tige 21 et pouvant se déplacer en translation le long de la tige 21 dans un alésage 63 d'axe 23 du boîtier 28. A la position d'équilibre, la pièce d'appui 62 prend appui contre un fond 64 de l'alésage 63. Dans cette même position, la pièce d'appui 62 prend appui contre un épaulement 65 de la tige 21.In the example shown, the displacement of the
Les deux ressorts 60 et 61 sont hélicoïdaux Ils sont montés concentriquement autour de l'axe 23. L'alésage 63 est partiellement fermé par un couvercle 66 sur lequel prend appui le ressort 60 par une première de ses extrémités 60a, éventuellement par l'intermédiaire d'une rondelle 67. Une seconde extrémité 60b du ressort 60 prend appui contre la pièce d'appui 62. La tige 21 traverse la rondelle 67 et le couvercle 66. Le ressort 61 prend appui à une première de ses extrémité 61a contre une rondelle 68 solidaire de la tige 21 Une seconde extrémité 61b du ressort 61 prend appui contre la pièce d'appui 62. La rondelle 68 est rendue solidaire de la tige 21 au moyen d'un circlips 69 disposé dans une gorge 70 de la tige 21.The two springs 60 and 61 are helical. They are mounted concentrically around the
Lorsqu'un opérateur pousse sur la tige 21 suivant l'axe 23, le sens de déplacement de la tige 21 étant matérialisé par la flèche P, seul le ressort 60 est comprimé. La tige 21 se déplace par rapport au boîtier 28 et entraine la pièce d'appui 62 dans son déplacement par rapport au boîtier 28, ce qui comprime le ressort 60. La pièce d'appui 62 peut comporter un prolongement tubulaire 71 permettant de limiter le déplacement de la pièce d'appui 62 dans l'alésage 63. Le prolongement 71 peut venir en butée contre la rondelle 67 pour limiter le déplacement de la tige 21 dans le sens « pousser » P. Par contre, la pièce d'appui 62 reste en appui contre l'épaulement 65. Les rondelles 62 et 68 suivent toutes deux le déplacement de la tige 21. Ainsi le ressort 61 ne se déforme pas lorsque l'opérateur pousse sur la tige 21.When an operator pushes on the
A l'inverse, lorsqu'un opérateur tire sur la tige 21 suivant l'axe 23, le sens de déplacement de la tige 21 étant matérialisé par la flèche T, seul le ressort 61 est comprimé.

On peut également prévoir une butée mécanique limitant le déplacement de la tige 21 dans le sens « tirer » T. Cette butée peut être formée par une surface 72 du boîtier 28 sur laquelle vient s'appuyer un épaulement 73 de la tige 21. Par contre, la rondelle 69 suit le mouvement de la tige 21 et comprime le ressort 61 contre la pièce d'appui 62.Conversely, when an operator pulls on the
