Definitions

  • the invention relates to a control device for a timepiece, the control device comprising a crown head movable in translation.
  • the invention also relates to a timepiece comprising such a control device.
  • Some timepieces are equipped with a control device used to actuate a mechanism of the timepiece such as a mechanism for winding a barrel or a mechanism for setting the time.
  • the control device comprises a crown head movable between two positions: a first position, called the disengaged position, is a position in which rotation of the crown head does not involve any particular mechanism.
  • a second position, called the engaged position is a position in which the crown head is coupled to a crown body.
  • a rotation of the crown head causes the rotation of the crown body which itself drives said mechanism.
  • the object of the invention is to provide a control device and a timepiece comprising such a control device remedying the above drawbacks and improving the control devices and timepieces known from the prior art.
  • a first object of the invention is a particularly compact, durable and simple to handle timepiece control device.
  • control device is defined by claim 1.
  • control device is defined by claim 5.
  • Embodiments of the control device are defined by claims 2 to 4 and 6 to 9.
  • the timepiece is defined by claim 10.
  • Embodiments of the timepiece are defined by claims 11 and 12.
  • THE figures 1 to 5 illustrate a control device 1 according to one embodiment of the invention.
  • the control device is integrated into a middle part 2 of a timepiece.
  • the timepiece may in particular be a wristwatch or a pocket watch.
  • Middle 2 is part of a timepiece case.
  • the caseband 2 comprises a side blank provided with an opening 21 of circular shape in which the control device 1 is arranged.
  • the control device 1 is connected to at least a first mechanism, or movement, of which an element 3 is partially visible on the figures 1 and 2 .
  • the first mechanism is arranged inside the case. It may for example be a winding mechanism for a barrel of the timepiece or a time setting mechanism.
  • the control device comprises in particular a body 4, which can also be called crown body, a crown head 5 and a locking element 6.
  • the body 4 is rotatably mounted in the middle part 2 about an axis of rotation X.
  • the body 4 comprises a cylindrical outer wall 41 forming a plain bearing cooperating with a cylindrical wall delimiting the opening 21 of the build.
  • the cooperation of the cylindrical outer wall 41 with the opening 21 ensures rotational guidance of the body 4 with respect to the middle part 2.
  • a seal 7, for example of toric shape, is advantageously provided at the interface between the wall external cylindrical 41 and the opening 21 to prevent the intrusion of particles and/or liquid inside the timepiece.
  • the seal 7 is arranged in a groove 42 provided in the cylindrical outer wall 41. It is dimensioned so as to come into contact with the cylindrical wall of the middle part 2 delimiting the opening 21.
  • the groove could also be provided at the level of the cylindrical wall delimiting the opening 21, the seal maintained in this groove would then cooperate with a cylindrical wall of the body 4.
  • the body 4 is held axially (that is to say parallel to the axis of rotation X) to the middle part 2.
  • the body 4 comprises a shoulder 43 held between on the one hand a surface 22 middle part 2 bordering the opening 21 and on the other hand a holding plate 8 fixed to the middle part 2.
  • a clearance is provided between the shoulder 43, the surface 22 and the holding plate 8 so as to allow a 4 body rotation without friction.
  • the body 4 is not mobile in translation relative to the middle part 2. It comprises a single degree of freedom in rotation relative to the middle part 2.
  • Body 4 is fixed to element 3 to drive said first mechanism.
  • the body 4 comprises an opening 44 of square section (clearly visible on the figure 5 ) and centered around the axis of rotation X.
  • the opening 44 accommodates a pin 31 integral with the element 3 and of complementary shape to the opening 44.
  • the connection between the element 3 and the body 4 could be obtained by any other means, in particular by screwing.
  • solid means a mechanical connection without degree of freedom. Two elements secured to each other are therefore two elements fixed to each other.
  • the retaining plate 8 comprises an opening 81 through which the pin 31 passes. It comprises a surface 82 coplanar with a surface of a base 45 of the body 4.
  • the retaining plate 8 further comprises a counterbore 83 in which takes place the shoulder 43.
  • the retaining plate does not increase the overall size of the control device.
  • the crown head 5 is movable in translation relative to the body 4, parallel to the axis of rotation X, between a first position, called the disengaged position (illustrated on the figure 1 ), and a second position, called the engaged position (illustrated in the figure 2 ).
  • the crown head mainly comprises a disk 51 intended to be manipulated with the fingers of a user and a tubular part 52 capable of cooperating with the body 4 when the crown head is in its second position.
  • the crown head 5 is configured to be pulled from its first position to its second position and pushed from its second position to its first position.
  • the first position of the crown head corresponds to a pushed position, or in other words retracted against the middle part 2.
  • the second position of the crown head corresponds to an extended or in other words pulled position. It is observed that the passage from the first position to the second position is not obtained by screwing or unscrewing the crown head.
  • the body 4 comprises an annular opening 49 capable of receiving the tubular part 52 of the crown head within it.
  • the annular opening 49 can accommodate the tubular part 52.
  • the annular opening 49 is centered around the axis of rotation X.
  • the annular opening 49 is delimited radially by a first wall 410, of generally cylindrical shape, forming an outer wall of the annular opening and by a second wall 411 forming an inner wall of the annular opening.
  • the annular opening 49 is blind, that is to say not through.
  • the first wall is connected to the second wall at the level of the base 45 of the body 4.
  • the depth of the annular opening 49 along the axis of rotation X is substantially equal to the height of the tubular part along this same axis.
  • the body 4 comprises a first coupling means 46 and the crown head 5 comprises a second coupling means 53.
  • the first coupling means 46 is formed by a first set of rectilinear splines. These grooves, also called serrations, are arranged parallel to the axis of rotation X and distributed along the first wall 410. More precisely still, the first set of grooves extends approximately over only one part (in particular over half) of the height of the first wall 410. The part of the wall 410 along which the first set of grooves extends is positioned more in the direction of the disc 51.
  • the wall 410 thus comprises a free zone 414 of any groove which is positioned more in the direction of base 45.
  • the second coupling means 53 is also formed by a second set of rectilinear grooves, arranged parallel to the axis of rotation X, and distributed along an outer wall 56 of the tubular part.
  • This outer wall 56 also has a cylindrical shape centered around the axis of rotation X.
  • the first set of rectilinear splines is particularly clearly visible on the figure 4 and the second set of rectilinear grooves is particularly clearly visible on the figure 5 .
  • the first coupling means 46 occupies a position offset along the axis of rotation X with respect to the second coupling means 53.
  • the first set of splines is not in contact with the second set of splines, so that the body 4 and the crown head 5 are uncoupled.
  • the first coupling means 46 is positioned opposite the second coupling means 53.
  • the first set of splines is nested with the second set of splines.
  • the body 4 and the crown head 5 are coupled, that is to say linked in rotation.
  • a rotation of the crown head around the axis of rotation X therefore drives the body 4 which itself drives the element 3 of the first mechanism.
  • the control device can thus be described as a disengageable crown control device.
  • the first coupling means 46 can be integrated into a ring 412 itself fixed to the body 4.
  • the ring 412 can in particular be secured to the body 4 by fitting.
  • the body 4 can be formed by assembling two parts, which facilitates its manufacturing process.
  • the body 4 could be a one-piece part machined from one and the same block of material.
  • the locking element 6 is an element for holding the crown head in position, or in other words an indexing means.
  • the element of lock 6 is configured to cooperate selectively with a first formation 47A and with a second formation 47B. More particularly, the locking element 6 is capable of cooperating with the first formation 47A to stabilize the crown head in its first position. Likewise, the locking element 6 is capable of cooperating with the second formation 47B to stabilize the crown head in its second position.
  • the set of the two formations 47A, 47B therefore more generally constitutes a first indexing means and the locking element 6 more generally constitutes a second indexing means capable of cooperating with the first indexing means.
  • the first position and the second position of the crown head are mechanically stable positions. When the crown head is moved close to its first position or its second position, the cooperation of the two indexing means makes it possible to position the crown head exactly in its first position or in its second position respectively.
  • the locking element 6 is integral with the crown head 5 and the first and second formations 47A, 47B are integral with the body.
  • the locking element 6 is held in a groove 54 of the tubular part 52.
  • the groove 54 is formed in an internal wall 55, of cylindrical shape, of the tubular part 52.
  • the dimensions of this groove 54 are such that there may be a small clearance between the edges of the groove and the locking element, in particular to allow deformation of the locking element 6 during use of the control device.
  • locking element integral with the crown head is meant a mechanical connection between these two elements ensuring sufficient retention of the locking element on the crown head to perform an indexing function.
  • the first and second formations are formed in the second wall 411 of the annular opening 49, facing the wall internal 55.
  • the first and second formations are positioned one beside the other along the longitudinal axis X.
  • the distance separating the first formation from the second formation along the axis of rotation X corresponds to the amplitude of displacement of the crown head between its first position and its second position.
  • the locking element 6 comprises a shape of revolution centered around the axis of rotation X, in particular a toroidal shape. It may for example be an elastomer ring or a rod.
  • the first and second formations are shaped grooves substantially complementary to the shape of a portion of the locking element. In particular the grooves have a section in the shape of an arc of a circle.
  • the locking element 6 compresses in the groove 54 and relaxes when it takes place in one or the other of the first or second formations.
  • the choice of the dimensions of the groove 54, of the locking element and of the first and second formations makes it possible to adjust the retaining force produced on the crown head to maintain it in its first position and in its second position.
  • the locking element 6 could be fixed to the body 4 and the first and second formations 47A, 47B could be fixed to the crown head.
  • the locking element could be held in a groove formed in the second wall 411 and the first and second formations could be made in the internal wall 55 of the tubular part.
  • first and second coupling means 46, 53 could be arranged respectively on the second wall 411 of the annular opening 49 and on the internal wall 55 of the tubular part 52, while that the element of lock 6 would be arranged on the outer wall 56 of the tubular part 52 and the first and second formations 47A, 47B would be arranged on the first wall 410 of the annular opening 49.
  • first and second coupling means 46, 53 could be arranged respectively on the second wall 411 of the annular opening 49 and on the internal wall 55 of the tubular part 52, while the locking element 6 would be arranged on the first wall 410 of the annular opening 49 and the first and second formations 47A, 47B would be arranged on the outer wall 56 of the tubular part 52.
  • the body 4 comprises three concentric walls 41, 410 and 411 each performing a function of the control device.
  • the first wall 410 accommodates the first coupling means and the free zone 414 devoid of coupling means
  • the second wall 411 accommodates an indexing means
  • the outer wall 41 forms the body 4 in rotational guidance. size of the body 4 along the axis of rotation X is therefore imposed only by the minimum height of each of these three walls 41, 410 and 411.
  • the annular opening 49 coincides with the tubular part 52 of the crown head which comprises two concentric walls 55, 56 each performing a function of the control device.
  • the inner wall 55 accommodates an indexing means and the outer wall 56 accommodates the second coupling means
  • the crown head further comprises rotation blocking means 57 configured to block the crown head in rotation when the crown head is in its first position.
  • the means of rotation blocking 57 is formed by a toothed wheel integral with the disc 51.
  • the toothed wheel is fixed, for example by fitting, to a lower face of the disc, that is to say the face of the disc 51 which is oriented towards the build. Thus the toothed wheel remains invisible and protected from shocks.
  • the toothed wheel is integrated in an annular groove provided in the disc 51.
  • the toothed wheel comprises a plurality of teeth extending radially, that is to say perpendicular to the axis of rotation X.
  • the toothed wheel cooperates with two lugs 23 formed in the middle part 2 when the crown head is in its first position to lock it in rotation.
  • the lugs 23 are each positioned between two adjacent teeth of the toothed wheel.
  • the number of lugs could be different: for example a single lug, three or more lugs, or even a number of lugs equal to the number of teeth of the toothed wheel.
  • the toothed wheel and the crown head could form one and the same one-piece piece.
  • the lugs could be integral with the disc 51 and cooperate with a crenellated opening formed in the caseband.
  • control device 1 also comprises a retaining means 9 cooperating with a retaining surface 58 of the crown head to limit the movement in translation of the crown head parallel to the axis of rotation X.
  • the retaining means 9 is formed by a retaining screw, secured to the body 4 and passing through an opening 59 of the crown head.
  • the retaining screw extends parallel to the axis of rotation X and is centered on this axis of rotation. It cooperates with a threaded opening 413 provided in the center of the body 4.
  • the retaining screw comprises a screw head 91 forming an abutment cooperating with the retaining surface 58 to prevent dissociation of the crown head from the body 4.
  • the control device 1 could not include such a retaining means since the cooperation of the locking element with the formation 47B already provides a first retaining means of the crown head to the body.
  • the diameter of the second wall 411 could be slightly increased, at least at the level of a portion 414 of the second wall between the formation 47B and the edge of this second wall.
  • the assembly of the crown head to the body 4 could be achieved by forcing the retaining element 6 in interference with the portion 414 and/or by heating or cooling respectively the crown head 5 or the body 4.
  • the force necessary to force the retaining element 6 at the level of the portion 414 would then be much greater than that usually applied by a user to pass the crown head from its first position to its second position, which would prevent untimely dissociation of the crown head.
  • the timepiece can advantageously comprise a first mechanism, in particular a barrel winding mechanism, and a second mechanism, in particular a time setting mechanism.
  • the body 4 can be linked directly or indirectly to the first mechanism so that the first mechanism is activated when the crown head is turned in a first direction of rotation.
  • the body 4 can be linked directly or indirectly to the second mechanism so that the second mechanism is activated when the crown head is turned according to a second direction of rotation, opposite to the first direction of rotation.
  • the visible face of disc 51 can thus include informative or aesthetic patterns such as arrows indicating that the crown head can be actuated in two opposite directions of rotation.
  • disc 51 may also include an outer rim provided with a pattern such as a set of slots in order to improve the grip of the fingers on the crown head.
  • the rotation blocking means 57 could be constituted by all the slots arranged on the outer periphery of the disc 51, and not by the toothed wheel arranged on the underside of the disc. Thus, the method of manufacturing the control device could be facilitated.
  • the crown head when the crown head is in its first position, it is immobilized in rotation thanks to the cooperation of the rotation locking means 57 with the two lugs 23 of the middle part 2. Consequently, there is no slippage at the interface between the locking element 6 and the body 4 and the locking element 6 does not wear out.
  • the crown head does not risk pivoting following undesired manipulation, it can therefore maintain a given position, which makes it possible to optimize the overall aesthetics of the timepiece.
  • the body 4 is uncoupled from the crown head 5 and can optionally rotate freely around the axis of rotation X, without driving the crown head in rotation.
  • the element 3 of the first mechanism can therefore also rotate around the axis of rotation X.
  • the user of the timepiece grasps the disc 51 and pulls it parallel to the axis of rotation X.
  • the rotation blocking means 57 disengages from the lugs 23. This which makes it possible to rotate the head of the crown.
  • the first and second coupling means are positioned opposite each other.
  • the crown head 5 is then integral in rotation with the body 4. As a remark in the event that the first set of splines is not positioned well opposite the second set of splines, a rotation of the crown head relative to the body may be required. This rotation is all the lower as the number of splines making up the first and second sets of splines increases.
  • the ends of the splines can be beveled to facilitate the engagement of the splines. If the body 4 has remained stationary while the crown head was in its first position, the first set of splines is automatically aligned with the second set of splines.
  • the first and second coupling means cooperate so as to secure the crown head to the body 4 in rotation.
  • the user turn the crown head in one direction or the other around the axis of rotation X of which drives the element 3 in rotation. Due to the coupling between the crown head and the body, there is no relative displacement in rotation between these two components. Consequently, the locking element is not subjected to any force linked to its sliding against the body 4 and it does not wear out.
  • the first and second coupling means uncouple.
  • a slight rotation of the crown may possibly be necessary for the lugs 23 to take place between two adjacent teeth of the rotation blocking means 57.
  • the invention there is a control device whose crown head is movable between a disengaged position and a position engaged with the body. Thanks to the cooperation of the locking element with first and second formations, the two positions of the crown head are stable positions. When the crown head is operated in rotation, the locking element does not slip relative to the body. Therefore no wear of the locking element appears over the use of the control device. The stability of the first and second positions of the crown head is thus preserved throughout the life of the timepiece. In addition, the control device thus obtained is particularly compact. It can easily fit into the smallest timepieces.
