Definitions
- the present invention relates to a device for controlling at least two electronic and / or mechanical functions for a portable object of small dimensions. More specifically, the invention relates to such a device comprising a control rod provided with a mechanical position indexing device which makes it possible to make each electronic or mechanical function coincide with a position distinct from the control rod.
- the present invention relates to the field of control rods which equip portable objects of small dimensions such as timepieces and which are arranged to control one or more electronic and / or mechanical functions of such objects.
- control rods of this type comprise a cylindrical portion whose length is substantially greater than the diameter and at one end of which is located outside the portable object is fixed a crown allowing a user of operate the control rod and adjust the electronic or mechanical function (s).
- these rods control several functions, it is necessary to be able to match each given function with a determined position of the control rod.
- FIG. figure 22 An example of such a control rod is shown in FIG. figure 22 attached to this patent application.
- this control rod comprises a cylindrical portion 202 terminated at its end located outside the portable object (not shown) which is equipped with an actuating ring 204.
- the cylindrical portion 202 of the control rod 200 is provided with a cam path 206 formed of three successive annular grooves 208a, 208b and 208c separated from each other by two beads 210a and 210b with substantially rounded profiles.
- the dimensions of the annular grooves 208a-208c are adapted to those of the elastic arms 212 of a spring 214 for example U-shaped protruding for example in the annular groove 208a of the cam path 206. It is understood that to pass the elastic arms 212 of the spring 214 of the annular groove 208a in the annular groove 208b, it is necessary that the user exerts on the control rod 200 a tensile force greater than the force required for these elastic arms 212 to move and slide on the bead 210a before closing on the annular groove 208b.
- the object of the present invention is to remedy the problems mentioned above as well as to others by providing a device for controlling at least two electronic and / or mechanical functions comprising a rod whose diameter is small enough that it can be used especially in the field of watchmaking.
- the present invention relates to a device for controlling at least two electronic and / or mechanical functions of a portable object of small dimensions, this device comprising an axially movable control rod between at least a first and a second position, this control rod being provided at a first end with an actuating member, and being provided to a second end of a position indexing plate arranged to cooperate with an elastic member to coincide each of the first and second positions of the control rod with one of the mechanical or electronic functions.
- the present invention provides a device for controlling at least two electronic or mechanical functions whose dimensions are contained, which makes it possible to install such a control device in a portable object of small dimensions such as in particular a wristwatch.
- the mechanical structure that indexes the position of the control rod is moved from the actual control rod to a position indexing plate which is machined separately from the control rod.
- a position indexing plate which is machined separately from the control rod.
- Such a plate is relatively thin and further extends in a substantially horizontal plane, whereas, when the mechanical indexing structure of the position is formed on the control rod, it makes it necessary to increase the diameter of the control rod and therefore the height of the middle part of the portable object, so that the portable object is thicker, which is to be avoided especially in the field of timepieces.
- the friction is virtually eliminated in order to limit the wear to the maximum and to guarantee a longevity of the most important control device possible.
- the less friction is important the easier is the manipulation of the control rod, particularly in unstable thrust position.
- control rod and the indexing plate are not mounted in an indissociable manner makes it possible to guarantee the dismountability of the control device, which is advantageous in particularly in the case where the timepiece equipped with the control device according to the invention is of a certain price.
- the present invention proceeds from the general inventive idea of transferring an indexing mechanism of the position of a control rod of at least two electronic and / or mechanical functions of a portable object of small dimensions such as a timepiece from this control rod to a plate machined separately from said control rod.
- a control rod of at least two electronic and / or mechanical functions of a portable object of small dimensions such as a timepiece
- a plate machined separately from said control rod By proceeding in this way, it is possible to reduce the diameter of the control rod and therefore reduce concomitantly the thickness of the middle part of the portable object such as a timepiece.
- the indexing mechanism which is typically in the form of two cam paths cooperating with an elastic member, instead of being structured directly on the control rod, is made in a thin plate which constitutes a separate part of the control rod and which is mechanically coupled with the latter.
- the control rod is devoid of its indexing mechanism, its diameter can be decreased, and the position indexing plate according to the invention, because of its small thickness, does not cause a significant
- the direction from rear to front is a rectilinear direction which extends horizontally along the longitudinal axis of symmetry XX of the control rod from the outer actuating ring towards the inside of the portable object equipped with the control device.
- the control rod will be pushed from the back to the front, and will be pulled from the front to the back.
- the vertical direction z is a direction that extends perpendicularly to the plane in which the control rod extends.
- the figure 1 is a perspective view in the dissociated state of a device for controlling at least one electronic function of a small portable object such as a wristwatch.
- this control device comprises (see figure 2 ) a lower frame 2 for example made of an injected plastic material or a non-magnetic metallic material such as brass.
- This lower frame 2 serves as a cradle for a control rod 4 of preferentially elongate and substantially cylindrical shape, provided with a longitudinal axis of symmetry XX (see FIG. figure 3 ).
- This control rod 4 is arranged to slide back and forth forwards along its longitudinal axis of symmetry XX , and / or to rotate about the same longitudinal axis of symmetry XX in a clockwise and counterclockwise direction. .
- control rod 4 At a rear end 6 which will be located outside the portable object once it is equipped with a control device 1, the control rod 4 will receive an actuating ring 8 (see FIG. figure 18 ).
- control rod 4 At a front end 10 which will be located inside the control device 1 once it is assembled, the control rod 4 has a section 12, for example square, and successively receives a magnetic unit 14 and a plain bearing 16.
- the magnetic assembly 14 comprises a bipolar or multipole magnetic ring 18 and a support ring 20 on which the magnetic ring 18 is fixed typically by gluing (see FIG. figure 4 ).
- the support ring 20 is a generally cylindrical piece. As visible on the figure 5 , the support ring 20 has, from the rear towards the front, a first section 22a of a first outer diameter D1 on which is engaged the magnetic ring 18, and a second section 22b of a second outer diameter D2 greater than the first outer diameter D1 and which delimits a shoulder 24 against which the magnetic ring 18 bears.
- the first section 22a of the support ring 20 is pierced with a square hole 26 which is adapted in shape and size to the square section 12 of the control rod 4 and forms with this control rod 4 a pinion type system flowing.
- the support ring 20 and the magnetized ring 18 remain stationary when sliding axially the control rod 4.
- the control rod 4 drives the support ring 20 and the magnetic ring 18 in rotation when this control rod 4 is rotated. It is understood from the foregoing that the magnetic ring 18, carried by the support ring 20, is not in contact with the control rod 4, which allows to protect it in case of shocks applied to the portable object equipped with a control device 1.
- the plain bearing 16 defines (see figure 5 ) a cylindrical housing 28 whose first inner diameter D3 is very slightly greater than the diameter of the circle in which the square section 12 of the control rod 4 fits in order to allow this control rod 4 to slide axially and / or to rotate inside this cylindrical housing 28.
- the sliding bearing 16 thus ensures the perfect axial guidance of the control rod 4.
- the square hole 26 formed in the first section 22a of the support ring 20 is extended towards the front of the control device 1 by an annular hole 30 whose second internal diameter D4 is adjusted to the third outer diameter D5 of the 16.
- the support ring 20 is thus threaded free to rotate on the plain bearing 16 and comes into axial abutment against this sliding bearing 16, which guarantees the perfect axial alignment of these two parts and makes it possible to correct the problems of concentricity. that a coupling of the sliding gear type can pose.
- the sliding bearing 16 is provided on its outer surface with a circular flange 32 which protrudes into a first groove 34a and a second groove 34b respectively formed in the lower frame 2 (see FIG. figure 2 ) and in an upper frame 36 (see figure 6 ) arranged to cap the lower frame 2 and made for example of an injected plastic material or a non-magnetic metallic material such as brass.
- a circular flange 32 which protrudes into a first groove 34a and a second groove 34b respectively formed in the lower frame 2 (see FIG. figure 2 ) and in an upper frame 36 (see figure 6 ) arranged to cap the lower frame 2 and made for example of an injected plastic material or a non-magnetic metallic material such as brass.
- the magnetic assembly 14 and the plain bearing 16 described above are for illustrative purposes only.
- the plain bearing 16 for example made of steel or brass, is provided to prevent the control rod 4, for example made of steel, from rubbing against the lower frame 2 and upper 36 and causes wear of the material plastic in which these two lower frames 2 and upper 36 are typically made.
- the control rod 4 is directly carried by the lower frame 2.
- the magnetic ring 18 and the support ring 20 on which the magnet ring 18 is fixed are provided for the case where the rotation of the control rod 4 is detected by a local variation of the magnetic field induced by the pivoting of the magnetic ring 18.
- the magnetic assembly 14 for example by a sliding pinion which, according to its position, will for example control the winding of a mainspring or the setting at the time of a watch equipped with the control device 1.
- control rod 4 provided over a portion of its length with a square section is given for illustrative purposes only. Indeed, to drive the magnetic assembly 14 in rotation, the control rod 4 may have any type of section which deviates from a circular section, for example triangular or oval.
- the lower frame 2 and the upper frame 36 whose assembly defines the external geometry of the control device 1 are for example of generally parallelepipedal shape.
- the lower frame 2 forms a cradle which receives the control rod 4 (see figure 2 ).
- the lower frame 2 comprises forwards a first receiving surface 38 of semicircular profile which serves as a seat for the sliding bearing 16 and in which is provided the first groove 34a which receives the circular flange 32. The immobilization of the sliding bearing 16 both axially and rotation is thus ensured.
- the lower frame 2 further comprises a rearwardly a second receiving surface 40 whose semicircular profile is centered on the longitudinal axis of symmetry XX of the control rod 4, but whose diameter is greater than that of this control rod 4. It is important to understand that the control rod 4 bears on the second receiving surface 40 only at the stage where the control device 1, assembled, is tested before being integrated into the portable object. At this stage of the assembly, the control rod 4 is introduced into the control device 1 for testing purposes and extends horizontally while being supported and guided axially by the sliding bearing 16 on the side of its front end 10 and by the second receiving surface 40 on the side of its rear end 6. By cons, once the control device 1 integrated in the portable object, the control rod 4 passes through a hole 42 formed in the middle 48 of the object notebook in which it is guided and supported (see figure 19 ).
- Third and fourth clearance surfaces 44a and 46a of semicircular profile are also provided in the lower frame 2 and complementary release surfaces 44b and 46b (see figure 6 ) are provided in the upper frame 36 to receive the magnetic assembly 14 consisting of the magnetic ring 18 and its support ring 20.
- the magnetic ring 18 and its support ring 20 are not in contact with the third and fourth clearance surfaces 44a, 46a and the complementary clearance surfaces 44b and 46b when the control device 1 is assembled and mounted in the portable object.
- the third clearance surface 44a and its corresponding complementary clearance surface 44b are delimited by a circular flange 50 for the axial locking of the magnetic assembly 14.
- the control rod 4 has a cylindrical section 52 whose diameter is included between the diameter of the circle in which the square section 12 of the control rod 4 fits and the pitch diameter of a rear section 54 of the same control rod 4 at the end of which is fixed the crown of
- This cylindrical section 52 of reduced diameter forms a groove 56 in which is placed a plate 58 for indexing the position of the control rod 4 (see FIG. Figures 7A and 7B ).
- the position indexing plate 58 has a curved portion 60 which matches the profile of the cylindrical section 52 of reduced diameter and which allows the position indexing plate 58 to extend substantially horizontally.
- the position indexing plate 58 may for example be obtained by stamping a thin metal sheet electrically conductive.
- this position indexing plate 58 for example by molding a hard plastic material loaded with conductive particles.
- the engagement of the position indexing plate 58 in the groove 56 ensures translation coupling back and forth forwards between the control rod 4 and the position indexing plate 58.
- the position index plate 58 is free with respect to the control rod 4 in a vertical direction z perpendicular to the longitudinal axis of symmetry XX of the control rod 4.
- the position indexing plate 58 is a substantially flat and generally U-shaped piece.
- This position indexing plate 58 comprises two substantially rectilinear guide arms 62 which extend parallel to each other and which are connected to one another. one to the other by the curved portion 60. These two guide arms 62 are guided axially for example against two pins 64 formed in the lower frame 2. Guided by its two guide arms 62, the position index plate 58 slides along a flange 68 formed in the upper frame 36 and whose perimeter corresponds to that of the position index plate 58 (see figure 6 ).
- the position indexing plate 58 also comprises two fingers 66a, 66b which extend vertically downwards on either side of the two guide arms 62.
- the position indexing plate 58 has the particular function of ensuring the translational guidance of the control rod 4 from front to back and back to front.
- the fingers 66a, 66b they make it possible in particular to prevent the position indexing plate 58 from bending when it moves in translation.
- Two openings 70 having a contour of approximately rectangular shape are formed in the guide arms 62 of the position indexing plate 58. These two openings 70 extend symmetrically on either side of the longitudinal axis of symmetry XX of the control rod 4.
- the sides of the two openings 70 closest to the longitudinal axis of symmetry XX of the control rod 4 have a cam path 72 of substantially sinusoidal shape formed of a first and a second hollow 74a and 74b separated by a vertex 76.
- the two openings 70 formed in the guide arms 62 are intended to receive the two ends 78 of a positioning spring 80 (see figure 8 ).
- This positioning spring 80 has a generally U-shaped shape with two rods 82 which extend in a horizontal plane and which are interconnected by a base 84. At their free end, the two rods 82 are extended by two arms 86 substantially rectilinear standing vertically.
- the positioning spring 80 is intended to be mounted in the control device 1 from below the lower frame 2, so that the ends 78 of the arms 86 project into the openings 70 of the position indexing plate 58. It will be seen below that the cooperation between the position indexing plate 58 and the positioning spring 80 makes it possible to index the position of the control rod 4 between an unstable thrust position T0 and two stable positions T1 and T2.
- the position indexing plate 58 is coupled in translation with the control rod 4, but that it is free with respect to the control rod 4 in the vertical direction z . It is therefore necessary to take measures to prevent the position indexing plate 58 from disengaging from the control rod 4 under normal conditions of use, for example under the effect of gravity.
- a spring 88 for limiting the displacement of the position index plate 58 in the vertical direction z above and at a short distance from this position indexing plate 58.
- the displacement limiting spring 88 is trapped between the lower frame 2 and the upper frame 36 of the control device 1, but is not, under normal conditions of use, in contact with the position indexing plate 58, which makes it possible to avoid that spurious friction forces exerted on the control rod 4 which would make its handling difficult and cause a phenomenon of wear.
- the displacement limiting spring 88 is however sufficiently close to the position indexing plate 58 so that it can not decouple from the control rod 4 inadvertently.
- the displacement limiting spring 88 comprises a substantially rectilinear central portion 90 from the ends of which extend two pairs of elastic arms 92 and 94. These elastic arms 92 and 94 extend on either side of the part. 90 of the displacement limiting spring 88, moving away from the horizontal plane in which extends the central portion 90. These elastic arms 92 and 94, being compressed when the upper frame 36 is joined to the lower frame 2, give the displacement limiting spring 88 its elasticity in the vertical direction z .
- pairs of elastic arms 92 and 94 are also provided a pair and, preferably, two pairs of rigid tabs 96 which extend perpendicularly downwards on either side of the central portion 90 of the displacement limitation spring 88
- These rigid tabs 96 which bear on the lower frame 2 when the upper frame 36 is placed on the lower frame 2, guarantee the respect of a minimum spacing between the position indexing plate 58 and the displacement limiting spring 88 under normal operating conditions of the control device 1.
- the displacement limiting spring 88 guarantees the dismountability of the control device 1.
- the position indexing plate 58 should be made integral with the control rod 4 and as a result, the control rod 4 could no longer be disassembled.
- the control rod 4 could not be disassembled, the movement of the timepiece equipped with the control device 1 is also inconcemontable, which is not possible in particular in the case of a timepiece expensive.
- a disengagement plate 98 is provided to allow the disassembly of the control rod 4 (see figure 10 ).
- This disengagement plate 98 is generally H-shaped and comprises a straight segment 100 which extends parallel to the longitudinal axis of symmetry XX of the control rod 4 and to which a first and a second transverse section 102 and 104 are attached.
- the first transverse section 102 is further provided at its two free ends with two tabs 106 folded at a substantially right angle.
- the disengagement plate 98 is received in a housing 108 formed in the lower frame 2 and located under the control rod 4. This housing 108 communicates with the outside of the device 1 via a hole 110 which opens into a lower face 112 of the control device 1 (see FIG. figure 11 ).
- the control rod 4 From its stable rest position T1, the control rod 4 can be pushed forward in an unstable position T0 or pulled in a stable position T2. These three positions T0, T1 and T2 of the control rod 4 are indexed by cooperation between the position index plate 58 and the positioning spring 80. More precisely (see figure12A ), the stable rest position T1 in which no control can be introduced into the portable object equipped with the control device 1 corresponds to the position in which the ends 78 of the arms 86 of the positioning spring 80 protrude into the first hollow 74a of the two openings 70 formed in the guide arms 62 of the position index plate 58. From this stable rest position T1, the control rod 4 can be pushed forward in an unstable position T0 (see figure 12B ).
- the ends 78 of the arms 86 of the positioning spring 80 leave the first recesses 74a and follow a first ramp profile 114 which progressively deviates from the longitudinal axis of symmetry XX of the control rod 4 according to a first abrupt ⁇ slope.
- the user To force the ends 78 of the arms 86 of the positioning spring 80 out of the first recesses 74a and to engage on the first ramp profile 114 away from each other, the user must therefore overcome a significant resisting stress.
- the ends 78 of the arms 86 engage on a second ramp profile 118 which extends the first profile in ramp 114 with a second slope ⁇ less than the first slope ⁇ of the first ramp profile 114.
- the effort that the user must provide to continue to advance the control rod 4 drops sharply and the user feels a click that indicates the transition of the control rod 4 between its T1 position and its T0 position.
- the arms 86 of the positioning spring 80 continue to move slightly away from their rest position and tend to want to come closer to one another under the effect of their force.
- First and second contact springs 120a and 120b are housed compressed in a first and a second cavity 122a and 122b formed in the lower frame 2.
- These first and second contact springs 120a and 120b may be chosen as helical contact springs, spring blades or others.
- the two cavities 122a, 122b extend preferentially but not necessarily horizontally. Because the two contact springs 120a, 120b are installed in the compressed state, the accuracy of their positioning is conditioned by the tolerance with which the lower frame 2 is manufactured. However, the precision with which the lower frame 2 is manufactured is is greater than the manufacturing accuracy of these two first and second contact springs 120a, 120b. Therefore, the detection accuracy of the position T0 of the control rod 4 is high.
- one of the ends of the first and second contact springs 120a, 120b is bent so as to form two contact tabs 124 which will come to bear on two corresponding first contact pads 126 provided on the surface of a sheet of flexible circuit board 128.
- the moment when the ends 78 of the arms 86 of the positioning spring 80 engage on the second ramp profile 118 of the two openings 70 formed in the position indexing plate 58 coincides with the moment when the fingers 66a, 66b of the position indexing plate 58 come into contact with the first and second contact springs 120a, 120b.
- this position indexing plate 58 is electrically conductive, when the fingers 66a, 66b contact the first and second contact springs 120a, 120b, the electrical current passes through the position indexing plate 58 and the closing of the electrical contact between the first and second contact springs 120a, 120b is detected.
- the first and second contact springs 120a, 120b are of the same length. However, preferably, one of the first and second cavities 122a, 122b will be longer than the other in particular to take account of tolerance problems (the difference in length between the two cavities 122a, 122b is a few tenths of a millimeter ). In this way, when pushing the control rod 4 forward to its position T0, the finger 66a of the position indexing plate 58 which is in correspondence with the first contact spring 120a housed in the first cavity 122a the longest will come in contact with it and start compressing it.
- the control rod 4 will continue to advance and the second finger 66b of the position indexing plate 58 will come into contact with the second contact spring 120b housed in the second cavity 122b the shortest. At this time, the position indexing plate 58 will be in contact with the first and second contact springs 120a, 120b and the electric current will pass through the position index plate 58, allowing to detect the closing the electrical contact between the two first contact springs 120a, 120b. Note that the fingers 66a, 66b of the position indexing plate 58 come into abutting contact with the first and second contact springs 120a, 120b. There is therefore no friction or wear when the control rod 4 is pushed forward in position T0 and closes the circuit between the first and second contact springs 120a, 120b.
- the first contact spring 120a housed in the longest first cavity 122a is at the same time. compressed state. Therefore, when the user releases the pressure on the control rod 4, this first contact spring 120a relaxes and forces the return of the control rod 4 from its unstable thrust position T0 to its first stable position T1.
- the first and second contact springs 120a, 120b thus simultaneously play the role of electrical contact parts and elastic return means of the control rod 4 in its first stable position T1.
- the control rod 4 Since the first stable position T1, it is possible to pull the control rod 4 back into a second stable position T2 (see figure 12C ). During this movement, the ends 78 of the arms 86 of the positioning spring 80 will pass by elastically deforming first hollow 74a to the second hollow 74b crossing the vertices 76 of the two openings 70 formed in the guide arms 62 of the plate Position indexing 58.
- the control rod 4 arrives in its second stable position T2
- the two fingers 66a, 66b of the position indexing plate 58 abut against third and fourth contact springs 130a, 130b (see figure 13 ) which are housed in third and fourth cavities 132a, 132b formed in the lower frame 2.
- third and fourth contact springs 130a and 130b can be the choice of helical contact springs, leaf springs or other.
- the third and fourth cavities 132a, 132b preferably extend vertically for dimensions of the control device 1.
- the fingers 66a, 66b of the position indexing plate 58 also come into abutting contact with the third and fourth contact springs 130a, 130b, so that any risk frictional wear is avoided.
- the third and fourth contact springs 130a, 130b are capable of flexing when the fingers 66a, 66b of the position indexing plate 58 strike them, and thus of absorbing a possible lack of precision in the positioning of the position index plate 58.
- the third and fourth contact springs 130a, 130b are arranged to work in bending. Indeed, with contact springs 130a, 130b whose diameter is constant, the fingers 66a, 66b of the position indexing plate 58 come into contact with the contact springs 130a, 130b according to a large surface close to their points anchoring in the lower frame 2 and the upper frame 36. The proximity of the contact surface with the anchor points of the contact springs 130a, 130b induces in these contact springs 130a, 130b shear stresses which can lead to at premature wear and breakage of these.
- the contact springs 130a, 130b are preferably substantially half-way up in diameter 134 with which the fingers 66a, 66b of the position indexing plate 58 come into contact when the control rod 4 is pulled into its stable T2 position (see Figures 14A and 14B ).
- the third and fourth contact springs 130a, 130b are guided in two holes 136 formed in the upper frame 36 and come into contact with second contact pads 138 provided on the surface of the flexible printed circuit sheet 128 It is understood that, when the control rod 4 is pulled back to its stable position T2, the fingers 66a, 66b of the position index plate 58 come into contact with a reduced surface with the third and fourth springs. 130a and 130b at their largest diameter 134, which allows these contact springs 130a, 130b to flex between their two anchor points in the lower frame 2 and the upper frame 36.
- the flexible printed circuit sheet 128 is fixed on a plate 140 located on the side of a dial of the portable object. It has in particular a cut 142 adapted in shape and size to receive the upper frame 36. A portion 144 of the flexible printed circuit sheet 128 remains free (see figure 16 ). This free portion 144 of the flexible printed circuit sheet 128 carries a plurality of electronic components 146 as well as third contact pads 148 on which two inductive sensors 150 are fixed.

- it may be a Hall effect sensor or a magnetoresistive component type AMR (Anisostropic Magnetoresistance), GMR (Giant Magnetoresistance) or TMR (Tunneling Magnetoresistance).
- the free portion 144 of the flexible printed circuit sheet 128 is connected to the remainder of the flexible printed circuit sheet 128 by two strips 152 which allow the free portion 144 to be folded around the assembly of the upper frame 36 and the lower frame 2 , then fold down the free portion 144 against a lower surface 112 of the lower frame 2, so that the inductive sensors 150 enter two housings 156 formed in the lower surface 112 of the lower frame 2.

Description
La présente invention concerne un dispositif pour la commande d'au moins deux fonctions électroniques et/ou mécaniques pour un objet portable de petites dimensions. Plus précisément, l'invention concerne un tel dispositif comprenant une tige de commande munie d'un dispositif mécanique d'indexation de position qui permet de faire coïncider chaque fonction électronique ou mécanique avec une position distincte de la tige de commande.The present invention relates to a device for controlling at least two electronic and / or mechanical functions for a portable object of small dimensions. More specifically, the invention relates to such a device comprising a control rod provided with a mechanical position indexing device which makes it possible to make each electronic or mechanical function coincide with a position distinct from the control rod.
La présente invention concerne le domaine des tiges de commande qui équipent des objets portables de petites dimensions tels que des pièces d'horlogerie et qui sont agencées pour commander une ou plusieurs fonctions électroniques et/ou mécaniques de tels objets.The present invention relates to the field of control rods which equip portable objects of small dimensions such as timepieces and which are arranged to control one or more electronic and / or mechanical functions of such objects.
De manière très simplifiée, les tiges de commande de ce type comprennent une portion cylindrique dont la longueur est sensiblement supérieure au diamètre et à une extrémité de laquelle située à l'extérieur de l'objet portable est fixée une couronne permettant à un utilisateur d'actionner la tige de commande et de régler la ou les fonctions électroniques ou mécaniques. Dans le cas où ces tiges commandent plusieurs fonctions, il est nécessaire de pouvoir faire coïncider chaque fonction donnée avec une position déterminée de la tige de commande.In a very simplified manner, the control rods of this type comprise a cylindrical portion whose length is substantially greater than the diameter and at one end of which is located outside the portable object is fixed a crown allowing a user of operate the control rod and adjust the electronic or mechanical function (s). In the case where these rods control several functions, it is necessary to be able to match each given function with a determined position of the control rod.
Un exemple d'une telle tige de commande est illustré à la
Ainsi, par coopération entre les bras élastiques d'un ressort et un chemin de came qui vient de matière avec la portion cylindrique d'une tige de commande, il est avantageusement possible de définir par exemple trois positions stables de la tige de commande qui correspondent chacune au réglage d'une fonction donnée. L'inconvénient de cette solution réside cependant dans le fait que, pour pouvoir usiner le chemin de came dans la portion cylindrique de la tige de commande, il faut que le diamètre de la portion cylindrique de la tige de commande soit relativement grand, ce qui rend l'utilisation d'une telle tige de commande assez difficile, voire impossible, notamment dans le domaine des montres-bracelets où l'on ne souhaite pas devoir usiner des trous de forts diamètres dans la carrure, en particulier pour des questions d'épaisseur de la carrure.Thus, by cooperation between the elastic arms of a spring and a cam path which comes from the cylindrical portion of a control rod, it is advantageously possible to define, for example, three stable positions of the control rod which correspond to each at the setting of a given function. The disadvantage of this solution however lies in the fact that, in order to be able to machine the cam path in the cylindrical portion of the control rod, it is necessary that the diameter of the cylindrical portion of the control rod is relatively large, which makes the use of such a control rod quite difficult or impossible, especially in the field of wristwatches where one does not wish to have to machine holes in strong diameters in the middle, especially for matters of thickness of the middle part.
La présente invention a pour but de remédier aux problèmes mentionnés ci-dessus ainsi qu'à d'autres encore en procurant un dispositif de commande d'au moins deux fonctions électroniques et/ou mécaniques comprenant une tige dont le diamètre soit suffisamment petit pour qu'elle puisse être utilisée notamment dans le domaine de l'horlogerie.The object of the present invention is to remedy the problems mentioned above as well as to others by providing a device for controlling at least two electronic and / or mechanical functions comprising a rod whose diameter is small enough that it can be used especially in the field of watchmaking.
A cet effet, la présente invention concerne un dispositif pour la commande d'au moins deux fonctions électroniques et/ou mécaniques d'un objet portable de petites dimensions, ce dispositif comprenant une tige de commande mobile axialement entre au moins une première et une seconde position, cette tige de commande étant munie à une première extrémité d'un organe d'actionnement, et étant munie vers une seconde extrémité d'une plaque d'indexation de position agencée pour coopérer avec un organe élastique afin de faire coïncider chacune des première et seconde positions de la tige de commande avec l'une des fonctions mécanique ou électronique.For this purpose, the present invention relates to a device for controlling at least two electronic and / or mechanical functions of a portable object of small dimensions, this device comprising an axially movable control rod between at least a first and a second position, this control rod being provided at a first end with an actuating member, and being provided to a second end of a position indexing plate arranged to cooperate with an elastic member to coincide each of the first and second positions of the control rod with one of the mechanical or electronic functions.
Conformément à d'autres caractéristiques de l'invention qui font l'objet des revendications dépendantes :
- la plaque d'indexation s'étend sensiblement dans un plan horizontal ;
- l'organe élastique comprend deux bras élastiques qui coopèrent avec deux chemins de came identiques ménagés dans la plaque d'indexation de position pour définir la première et la seconde position de la tige de commande ;
- les deux chemins de came définissent une position instable et une position stable de la tige de commande, ou bien les deux chemins de came définissent une première et une seconde position stable de la tige de commande ;
- dans le cas où les deux chemins de came définissent une première position stable et une seconde position stable de la tige de commande, les chemins de came comprennent un premier creux séparé d'un second creux par un sommet, les premier et second creux définissant les première et seconde positions stables de la tige de commande, les bras élastiques de l'organe élastique passant du premier creux au second creux et vice et versa en franchissant le sommet ;
- dans le cas où les deux chemins de came définissent une position stable et une position instable de la tige de commande, les chemins de came comprennent un creux qui définit la position stable et duquel les bras élastiques de l'organe élastique sortent pour s'engager sur un profil en rampe qui éloigne les bras élastiques de leur position de repos et qui définit la position instable de la tige de commande ;
- la plaque d'indexation de position est logée dans une rainure ménagée dans la tige de commande ;
- la plaque d'indexation de position est solidaire de la tige de commande, ou bien la plaque d'indexation de position est couplée de manière amovible avec la tige de commande ;
- dans le cas où la plaque d'indexation de position est couplée de manière amovible avec la tige de commande, le couplage entre la plaque d'indexation de position et la tige de commande est un couplage élastique prévu pour empêcher le désaccouplement entre la plaque d'indexation de position et la tige de commande en conditions normales d'utilisation.
- the indexing plate extends substantially in a horizontal plane;
- the resilient member comprises two resilient arms that cooperate with two identical cam paths in the position indexing plate to define the first and second positions of the control rod;
- the two cam paths define an unstable position and a stable position of the control rod, or the two cam paths define a first and a second stable position of the control rod;
- in the case where the two cam paths define a first stable position and a second stable position of the control rod, the cam paths comprise a first recess separated from a second recess by a vertex, the first and second recesses defining the first and second stable positions of the control rod, the resilient arms of the elastic member passing from the first hollow to the second hollow and vice versa over the top;
- in the case where the two cam paths define a stable position and an unstable position of the control rod, the cam paths comprise a recess which defines the stable position and from which the resilient arms of the elastic member come out to engage. on a ramp profile which moves the elastic arms away from their rest position and which defines the unstable position of the control rod;
- the position indexing plate is housed in a groove in the control rod;
- the position indexing plate is integral with the control rod, or the position indexing plate is releasably coupled with the control rod;
- in the case where the position indexing plate is releasably coupled to the control rod, the coupling between the position indexing plate and the control rod is an elastic coupling provided to prevent disengagement between the control plate and the control rod. position indexing and the control rod under normal conditions of use.
Grâce à ces caractéristiques, la présente invention procure un dispositif pour la commande d'au moins deux fonctions électroniques ou mécaniques dont les dimensions sont contenues, ce qui permet d'installer un tel dispositif de commande dans un objet portable de petites dimensions tel que notamment une montre-bracelet. En effet, la structure mécanique qui permet d'indexer la position de la tige de commande est déplacée depuis la tige de commande proprement dite vers une plaque d'indexation de position qui est usinée séparément de la tige de commande. Une telle plaque est relativement mince et s'étend en outre dans un plan sensiblement horizontal, alors que, lorsque la structure mécanique d'indexation de la position est ménagée sur la tige de commande, elle oblige à augmenter le diamètre de la tige de commande et donc la hauteur de la carrure de l'objet portable, de sorte que l'objet portable est plus épais, ce que l'on cherche à éviter notamment dans le domaine des pièces d'horlogerie.Thanks to these characteristics, the present invention provides a device for controlling at least two electronic or mechanical functions whose dimensions are contained, which makes it possible to install such a control device in a portable object of small dimensions such as in particular a wristwatch. Indeed, the mechanical structure that indexes the position of the control rod is moved from the actual control rod to a position indexing plate which is machined separately from the control rod. Such a plate is relatively thin and further extends in a substantially horizontal plane, whereas, when the mechanical indexing structure of the position is formed on the control rod, it makes it necessary to increase the diameter of the control rod and therefore the height of the middle part of the portable object, so that the portable object is thicker, which is to be avoided especially in the field of timepieces.
D'autre part, dans le dispositif de commande selon l'invention, les frottements sont quasiment supprimés afin de limiter l'usure au maximum et de garantir une longévité du dispositif de commande la plus importante possible. En outre, moins les frottements sont importants, plus facile est la manipulation de la tige de commande, en particulier en position poussée instable. Dans le but de réduire ces frottements au maximum, il est tout particulièrement important de noter qu'aucun des contacts électriques qui se font dans le dispositif de commande selon l'invention ne se font par frottement. Tous les contacts électriques se font par butée d'une pièce contre une autre. On a donc beaucoup moins d'usure que dans le cas de pièces qui frottent les unes contre les autres. Il en va de même pour la plaque d'indexation de position dont le débattement vers le haut est limité par le ressort de limitation avec lequel la plaque d'indexation de position, et donc la tige de commande, n'est cependant pas en contact en conditions normales de fonctionnement. Dans ce cas également, on n'observe pas de frottement.On the other hand, in the control device according to the invention, the friction is virtually eliminated in order to limit the wear to the maximum and to guarantee a longevity of the most important control device possible. In addition, the less friction is important, the easier is the manipulation of the control rod, particularly in unstable thrust position. In order to reduce this friction to the maximum, it is particularly important to note that none of the electrical contacts that are made in the control device according to the invention are made by friction. All electrical contacts are abutting one piece against another. We therefore have much less wear than in the case of parts that rub against each other. The same is true for the position indexing plate whose upward movement is limited by the limiting spring with which the position indexing plate, and therefore the control rod, is not in contact, however. under normal operating conditions. In this case too, no friction is observed.
Enfin, le fait que la tige de commande et la plaque d'indexation ne soient pas montées de manière indissociable permet de garantir le caractère démontable du dispositif de commande, ce qui est avantageux en particulier dans le cas où la pièce d'horlogerie équipée du dispositif de commande selon l'invention est d'un certain prix.Finally, the fact that the control rod and the indexing plate are not mounted in an indissociable manner makes it possible to guarantee the dismountability of the control device, which is advantageous in particularly in the case where the timepiece equipped with the control device according to the invention is of a certain price.
On notera aussi que tous les contacts électriques qui s'opèrent dans le dispositif de commande selon l'invention sont de type galvanique, ce qui signifie qu'en l'absence de contact électrique, la consommation électrique du dispositif de commande est nulle.It will also be noted that all the electrical contacts that operate in the control device according to the invention are of the galvanic type, which means that in the absence of electrical contact, the electrical consumption of the control device is zero.

La présente invention procède de l'idée générale inventive qui consiste à transférer un mécanisme d'indexation de la position d'une tige de commande d'au moins deux fonctions électroniques et/ou mécaniques d'un objet portable de petites dimensions tel qu'une pièce d'horlogerie depuis cette tige de commande vers une plaque usinée séparément de ladite tige de commande. En procédant de la sorte, il est possible de réduire le diamètre de la tige de commande et donc de réduire concomitamment l'épaisseur de la carrure de l'objet portable tel qu'une pièce d'horlogerie. Ce résultat est atteint grâce au fait que le mécanisme d'indexation qui se présente typiquement sous la forme de deux chemins de came coopérant avec un organe élastique, au lieu d'être structuré directement sur la tige de commande, est réalisé dans une plaque mince qui constitue une pièce séparée de la tige de commande et qui est couplée mécaniquement avec cette dernière. Comme la tige de commande est dépourvue de son mécanisme d'indexation, son diamètre peut être diminué, et la plaque d'indexation de position selon l'invention, du fait de sa faible épaisseur, n'entraîne pas d'augmentation significative de l'encombrement de la tige de commande selon l'invention.The present invention proceeds from the general inventive idea of transferring an indexing mechanism of the position of a control rod of at least two electronic and / or mechanical functions of a portable object of small dimensions such as a timepiece from this control rod to a plate machined separately from said control rod. By proceeding in this way, it is possible to reduce the diameter of the control rod and therefore reduce concomitantly the thickness of the middle part of the portable object such as a timepiece. This result is achieved by the fact that the indexing mechanism which is typically in the form of two cam paths cooperating with an elastic member, instead of being structured directly on the control rod, is made in a thin plate which constitutes a separate part of the control rod and which is mechanically coupled with the latter. As the control rod is devoid of its indexing mechanism, its diameter can be decreased, and the position indexing plate according to the invention, because of its small thickness, does not cause a significant increase in Congestion of the control rod according to the invention.
Dans tout ce qui suit, la direction d'arrière en avant est une direction rectiligne qui s'étend horizontalement le long de l'axe longitudinal de symétrie X-X de la tige de commande depuis la couronne extérieure d'actionnement vers l'intérieur de l'objet portable équipé du dispositif de commande. Ainsi, la tige de commande sera poussée de l'arrière vers l'avant, et sera tirée de l'avant vers l'arrière. Par ailleurs, la direction verticale z est une direction qui s'étend perpendiculairement au plan dans lequel s'étend la tige de commande.In all that follows, the direction from rear to front is a rectilinear direction which extends horizontally along the longitudinal axis of symmetry XX of the control rod from the outer actuating ring towards the inside of the portable object equipped with the control device. Thus, the control rod will be pushed from the back to the front, and will be pulled from the front to the back. Moreover, the vertical direction z is a direction that extends perpendicularly to the plane in which the control rod extends.
La
A une extrémité arrière 6 qui sera située à l'extérieur de l'objet portable une fois celui-ci équipé d'un dispositif de commande 1, la tige de commande 4 recevra une couronne d'actionnement 8 (voir
A une extrémité avant 10 qui sera située à l'intérieur du dispositif de commande 1 une fois celui-ci assemblé, la tige de commande 4 présente une section 12 par exemple carrée et reçoit successivement un équipage magnétique 14 et un palier lisse 16.At a
L'équipage magnétique 14 comprend un anneau aimanté 18 bipolaire ou multipolaire et une bague-support 20 sur laquelle l'anneau aimanté 18 est fixé typiquement par collage (voir
Le palier lisse 16 définit (voir
On remarque que le trou carré 26 ménagé dans la première section 22a de la bague-support 20 est prolongé vers l'avant du dispositif de commande 1 par un trou annulaire 30 dont le second diamètre intérieur D4 est ajusté sur le troisième diamètre extérieur D5 du palier lisse 16. La bague-support 20 est ainsi enfilée libre en rotation sur le palier lisse 16 et vient en butée axiale contre ce palier lisse 16, ce qui garantit le parfait alignement axial de ces deux pièces et permet de corriger les problèmes de concentricité que peut poser un accouplement du type pignon coulant.Note that the
On observe que, pour son immobilisation axiale, le palier lisse 16 est muni sur sa surface extérieure d'une collerette circulaire 32 qui fait saillie dans une première gorge 34a et dans une seconde gorge 34b ménagées respectivement dans le bâti inférieur 2 (voir
Il est important de noter que l'équipage magnétique 14 et le palier lisse 16 décrits ci-dessus sont indiqués à titre purement illustratif seulement. En effet, le palier lisse 16, par exemple réalisé en acier ou en laiton, est prévu pour éviter que la tige de commande 4, par exemple réalisée en acier, ne frotte contre les bâtis inférieur 2 et supérieur 36 et provoque une usure du matériau plastique dans lequel ces deux bâtis inférieur 2 et supérieur 36 sont typiquement réalisés. Toutefois, dans un mode simplifié, on peut très bien envisager de ne pas utiliser un tel palier lisse 16 et de prévoir que la tige de commande 4 soit directement portée par le bâti inférieur 2.It is important to note that the
De même, l'anneau aimanté 18 et la bague-support 20 sur laquelle l'anneau aimanté 18 est fixé sont prévus pour le cas où l'on détecte la rotation de la tige de commande 4 par une variation locale du champ magnétique induite par le pivotement de l'anneau aimanté 18. Il est cependant tout à fait envisageable de remplacer l'équipage magnétique 14 par exemple par un pignon coulant qui, suivant sa position, va par exemple commander le remontage d'un ressort de barillet ou la mise à l'heure d'une montre équipée du dispositif de commande 1.Similarly, the
Il est aussi important de noter que l'exemple de la tige de commande 4 munie sur une partie de sa longueur d'une section carrée est donné à titre purement illustratif seulement. En effet, pour entraîner l'équipage magnétique 14 en rotation, la tige de commande 4 peut présenter tout type de section qui s'écarte d'une section circulaire, par exemple triangulaire ou ovale.It is also important to note that the example of the
Le bâti inférieur 2 et le bâti supérieur 36 dont la réunion définit la géométrie extérieure du dispositif de commande 1 sont par exemple de forme générale parallélépipédique. Le bâti inférieur 2 forme un berceau qui reçoit la tige de commande 4 (voir
Le bâti inférieur 2 comprend d'autre part vers l'arrière une deuxième surface de réception 40 dont le profil semi-circulaire est centré sur l'axe longitudinal de symétrie X-X de la tige de commande 4, mais dont le diamètre est supérieur à celui de cette tige de commande 4. Il est important de bien comprendre que la tige de commande 4 ne prend appui sur la deuxième surface de réception 40 qu'au stade où le dispositif de commande 1, assemblé, est testé avant d'être intégré dans l'objet portable. A ce stade du montage, la tige de commande 4 est introduite dans le dispositif de commande 1 à des fins de test et s'étend horizontalement en étant supportée et guidée axialement par le palier lisse 16 du côté de son extrémité avant 10 et par la deuxième surface de réception 40 du côté de son extrémité arrière 6. Par contre, une fois le dispositif de commande 1 intégré dans l'objet portable, la tige de commande 4 passe à travers un trou 42 ménagé dans la carrure 48 de l'objet portable dans lequel elle est guidée et supportée (voir
Des troisième et quatrième surfaces de dégagement 44a et 46a de profil semi-circulaire sont également prévues dans le bâti inférieur 2 et des surfaces de dégagement complémentaires 44b et 46b (voir

Deux ouvertures 70 présentant un contour de forme approximativement rectangulaire sont ménagées dans les bras de guidage 62 de la plaque d'indexation de position 58. Ces deux ouvertures 70 s'étendent symétriquement de part et d'autre de l'axe longitudinal de symétrie X-X de la tige de commande 4. Les côtés des deux ouvertures 70 les plus proches de l'axe longitudinal de symétrie X-X de la tige de commande 4 présentent un chemin de came 72 de forme sensiblement sinusoïdale formé d'un premier et d'un second creux 74a et 74b séparés par un sommet 76.Two
Les deux ouvertures 70 ménagées dans les bras de guidage 62 sont destinées à recevoir les deux extrémités 78 d'un ressort de positionnement 80 (voir
On a mentionné ci-dessus que la plaque d'indexation de position 58 est couplée en translation avec la tige de commande 4, mais qu'elle est libre par rapport à la tige de commande 4 selon la direction verticale z. Il est donc nécessaire de prendre des mesures pour empêcher la plaque d'indexation de position 58 de se désengager de la tige de commande 4 en conditions normales d'utilisation, par exemple sous l'effet de la pesanteur. A cet effet (voir
Le ressort de limitation du déplacement 88 comprend une partie centrale 90 sensiblement rectiligne à partir des extrémités de laquelle s'étendent deux paires de bras élastiques 92 et 94. Ces bras élastiques 92 et 94 s'étendent de part et d'autre de la partie centrale 90 du ressort de limitation du déplacement 88, en s'éloignant vers le haut du plan horizontal dans lequel s'étend cette partie centrale 90. Ces bras élastiques 92 et 94, en étant comprimés lorsque le bâti supérieur 36 est joint au bâti inférieur 2, confèrent au ressort de limitation du déplacement 88 son élasticité suivant la direction verticale z. Entre les paires de bras élastiques 92 et 94 sont également prévues une paire et, préférentiellement, deux paires de pattes rigides 96 qui s'étendent perpendiculairement vers le bas de part et d'autre de la partie centrale 90 du ressort de limitation du déplacement 88. Ces pattes rigides 96 qui viennent en appui sur le bâti inférieur 2 lorsque le bâti supérieur 36 est posé sur le bâti inférieur 2, garantissent le respect d'un espacement minimum entre la plaque d'indexation de position 58 et le ressort de limitation du déplacement 88 en conditions normales de fonctionnement du dispositif de commande 1.The
Le ressort de limitation du déplacement 88 garantit le caractère démontable du dispositif de commande 1. En effet, en l'absence du ressort de limitation du déplacement 88, la plaque d'indexation de position 58 devrait être rendue solidaire de la tige de commande 4 et, par suite, la tige de commande 4 ne pourrait plus être démontée. Or, si la tige de commande 4 ne peut être démontée, le mouvement de la pièce d'horlogerie équipée du dispositif de commande 1 est lui aussi indémontable, ce qui n'est pas envisageable notamment dans le cas d'une pièce d'horlogerie coûteuse. Ainsi, lorsque le dispositif de commande 1, formé par la réunion des bâtis inférieur 2 et supérieur 36, est monté dans l'objet portable et que l'on insère la tige de commande 4 dans le dispositif de commande 1 depuis l'extérieur de l'objet portable, la tige de commande 4 soulève légèrement la plaque d'indexation de position 58 à l'encontre de la force élastique du ressort de limitation du déplacement 88. En continuant de pousser en avant la tige de commande 4, arrive un moment où la plaque d'indexation de position 58 tombe dans la rainure 56 sous l'effet de la gravité. La tige de commande 4 et la plaque d'indexation de position 58 sont alors couplées en translation.The
Une plaque de déboîtement 98 est prévue pour permettre le démontage de la tige de commande 4 (voir
Depuis sa position stable de repos T1, la tige de commande 4 peut être poussée vers l'avant dans une position instable T0 ou tirée dans une position stable T2. Ces trois positions T0, T1 et T2 de la tige de commande 4 sont indexées par coopération entre la plaque d'indexation de position 58 et le ressort de positionnement 80. Plus précisément (voir
Arrivées à un point de transition 116, les extrémités 78 des bras 86 s'engagent sur un second profil en rampe 118 qui prolonge le premier profil en rampe 114 avec une seconde pente β inférieure à la première pente α du premier profil en rampe 114. A l'instant où les extrémités 78 des bras 86 du ressort de positionnement 80 franchissent le point de transition 116 et s'engagent sur le second profil en rampe 118, l'effort que l'utilisateur doit fournir pour continuer à faire avancer la tige de commande 4 chute brutalement et l'utilisateur ressent un déclic qui lui indique la transition de la tige de commande 4 entre sa position T1 et sa position T0. En suivant le second profil en rampe 118, les bras 86 du ressort de positionnement 80 continuent à s'écarter légèrement de leur position de repos et tendent à vouloir à nouveau se rapprocher l'une de l'autre sous l'effet de leur force élastique de rappel opposée à la force de poussée exercée par l'utilisateur sur la tige de commande 4. Aussitôt que l'utilisateur relâche sa pression sur la tige de commande 4, les bras 86 du ressort de positionnement 80 vont spontanément redescendre le long du premier profil en rampe 114 et venir à nouveau se loger dans les premiers creux 74a des deux ouvertures 70 ménagées dans les bras de guidage 62 de la plaque d'indexation de position 58. La tige de commande 4 est ainsi automatiquement rappelée de sa position instable T0 à sa première position stable T1.Arrived at a
Des premier et deuxième ressorts de contact 120a et 120b sont logés comprimés dans une première et une deuxième cavité 122a et 122b ménagées dans le bâti inférieur 2. Ces premier et deuxième ressorts de contact 120a et 120b peuvent être au choix des ressorts de contact hélicoïdaux, des lames ressorts ou autres. Les deux cavités 122a, 122b s'étendent préférentiellement mais non obligatoirement horizontalement. Du fait que les deux ressorts de contact 120a, 120b sont installés à l'état comprimé, la précision de leur positionnement est conditionnée par la tolérance avec laquelle est fabriqué le bâti inférieur 2. Or, la précision avec laquelle est fabriqué le bâti inférieur 2 est supérieure à la précision de fabrication de ces deux premier et deuxième ressorts de contact 120a, 120b. Par conséquent, la précision de détection de la position T0 de la tige de commande 4 est élevée.First and second contact springs 120a and 120b are housed compressed in a first and a
Comme visible sur les
Les premier et deuxième ressorts de contact 120a, 120b sont de même longueur. Cependant, de manière préférée, l'une des première et deuxième cavités 122a, 122b sera plus longue que l'autre notamment pour tenir compte des problèmes de tolérance (la différence de longueur entre les deux cavités 122a, 122b est de quelques dixièmes de millimètre). De cette manière, lorsqu'on pousse la tige de commande 4 en avant dans sa position T0, le doigt 66a de la plaque d'indexation de position 58 qui se trouve en correspondance avec le premier ressort de contact 120a logé dans la première cavité 122a la plus longue va venir en contact avec ce dernier et commencer à le comprimer. La tige de commande 4 va continuer à avancer et le second doigt 66b de la plaque d'indexation de position 58 va venir en contact avec le deuxième ressort de contact 120b logé dans la deuxième cavité 122b la plus courte. A ce moment-là, la plaque d'indexation de position 58 va se trouver en contact avec les premier et deuxième ressorts de contact 120a, 120b et le courant électrique va passer à travers la plaque d'indexation de position 58, ce qui permet de détecter la fermeture du contact électrique entre les deux premiers ressorts de contact 120a, 120b. On note que les doigts 66a, 66b de la plaque d'indexation de position 58 viennent en contact de butée avec les premier et deuxième ressorts de contact 120a, 120b. Il n'y a donc aucun frottement ni usure lorsque la tige de commande 4 est poussée en avant en position T0 et qu'elle ferme le circuit entre les premier et deuxième ressorts de contact 120a, 120b. On note aussi que, du fait de la longueur différente des première et deuxième cavités 122a et 122b, on est assuré que la fermeture du contact électrique et l'introduction de la commande correspondante dans l'objet portable équipé du dispositif de commande 1 n'intervient qu'après le ressenti du déclic.The first and second contact springs 120a, 120b are of the same length. However, preferably, one of the first and
Lorsque les deux doigts 66a, 66b de la plaque d'indexation de position 58 sont en contact avec les premier et deuxième ressorts de contact 120a ,120b, le premier ressort de contact 120a logé dans la première cavité 122a la plus longue est à l'état comprimé. Par conséquent, lorsque l'utilisateur relâche la pression sur la tige de commande 4, ce premier ressort de contact 120a se détend et force le retour de la tige de commande 4 de sa position poussée instable T0 à sa première position stable T1. Les premier et deuxième ressorts de contact 120a, 120b jouent donc simultanément le rôle de pièces de contact électrique et de moyen de rappel élastique de la tige de commande 4 dans sa première position stable T1.When the two
Depuis la première position stable T1, il est possible de tirer la tige de commande 4 en arrière dans une seconde position stable T2 (voir
On notera que, dans le cas de la position stable T2, les doigts 66a, 66b de la plaque d'indexation de position 58 viennent également en contact de butée avec les troisième et quatrième ressorts de contact 130a, 130b, de sorte que tout risque d'usure par frottement est évité. Par ailleurs, les troisième et quatrième ressorts de contact 130a, 130b sont capables de fléchir lorsque les doigts 66a, 66b de la plaque d'indexation de position 58 les heurtent, et donc d'absorber un éventuel manque de précision dans le positionnement de la plaque d'indexation de position 58.It will be noted that, in the case of the stable position T2, the
De préférence, mais non obligatoirement, les troisième et quatrième ressorts de contact 130a, 130b sont agencés pour travailler en flexion. En effet, avec des ressorts de contact 130a, 130b dont le diamètre est constant, les doigts 66a, 66b de la plaque d'indexation de position 58 viennent en contact avec les ressorts de contact 130a, 130b selon une surface importante proche de leurs points d'ancrage dans le bâti inférieur 2 et le bâti supérieur 36. La proximité de la surface de contact avec les points d'ancrage des ressorts de contact 130a, 130b induit dans ces ressorts de contact 130a, 130b des contraintes de cisaillement qui peuvent conduire à l'usure prématurée et à la rupture de ces derniers. Pour résoudre ce problème, les ressorts de contact 130a, 130b présentent de préférence sensiblement à mi-hauteur une augmentation de diamètre 134 avec laquelle les doigts 66a, 66b de la plaque d'indexation de position 58 viennent en contact lorsque la tige de commande 4 est tirée dans sa position stable T2 (voir

La portion libre 144 de la feuille de circuit imprimé flexible 128 est reliée au restant de la feuille de circuit imprimé flexible 128 par deux bandes 152 qui permettent de replier la portion libre 144 autour de l'assemblage du bâti supérieur 36 et du bâti inférieur 2, puis de rabattre la portion libre 144 contre une surface inférieure 112 du bâti inférieur 2, de façon que les capteurs inductifs 150 pénètrent dans deux logements 156 ménagés dans la surface inférieure 112 du bâti inférieur 2. Ainsi positionnés dans leurs logements 156, les capteurs inductifs 150 se trouvent précisément situés sous l'anneau aimanté 18, ce qui garantit une détection fiable du sens de rotation de la tige de commande 4. Une fois la portion libre 144 de la feuille de circuit imprimé flexible 128 rabattue contre le bâti inférieur 2 (voir
Il va de soi que la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples peuvent être envisagées par l'homme du métier sans sortir du cadre de l'invention tel que défini par les revendications annexées. En particulier, les dimensions de l'anneau aimanté peuvent être étendues de façon à le faire correspondre à un cylindre creux. On comprendra notamment que la plaque d'indexation de position 58 peut ne définir que deux positions distinctes, à savoir deux positions stables ou bien une position stable et une position instable, ou bien elle peut définir trois positions distinctes ou plus, à savoir au moins trois positions stables ou bien au moins deux positions stables et une position instable.It goes without saying that the present invention is not limited to the embodiment which has just been described and that various modifications and simple variants can be envisaged by those skilled in the art without departing from the scope of the invention as defined by the appended claims. In particular, the dimensions of the magnetized ring can be extended to match a hollow cylinder. It will be understood in particular that the

Plus précisément, la première position stable T1-1 correspond à la position dans laquelle les extrémités 78 des bras 86 du ressort de positionnement 80 font saillie dans les premiers creux 74a-1 des deux ouvertures 70-1 ménagées dans les bras de guidage 62 de la plaque d'indexation de position 58. Depuis cette première position stable T1-1, la tige de commande 4 peut être tirée en arrière dans une seconde position stable T2-1. Au cours de ce mouvement, les extrémités 78 des bras 86 du ressort de positionnement 80 vont passer en se déformant élastiquement des premiers creux 74a-1 aux second creux 74b-1 en franchissant les sommets 76-1 des deux ouvertures 70-1 ménagées dans les bras de guidage 62 de la plaque d'indexation de position 58.More precisely, the first stable position T1-1 corresponds to the position in which the ends 78 of the
