    The winding device (1) for a watch comprises a sun gear (2) mounted to rotate coaxially about a central axis on a winding wheel (5). The device comprises satellite gear wheels (3, 3 ') for meshing with a toothing of the sun gear (2). The planet wheels are mounted free of rotation with clearance (4) around a respective offset axis (7, 7 ') fixed on the winding wheel. The device also includes one or two hooks of a frame (6) fixedly mounted on the winding wheel. In a first direction of rotation of the sun gear, a locking position of a satellite wheel in contact with a hook occurs to drive the winding wheel. In a second direction of rotation opposite to the first direction of rotation, a disengagement of the satellite wheel takes place so that the rotation of the sun gear does not cause the winding wheel.

    专利说明:

    The invention relates to a winding device with unidirectional drive arrangement for a watch. This device can be used for winding or winding a barrel spring for driving a clockwork movement or for driving, for example, a date or time correction disc. The device comprises at least one solar drive gear rotatably mounted about a central axis arranged coaxially on a winding wheel, which can be connected to the motor spring barrel of the clockwork movement.
    Usually for a winding system of at least one cylinder or reset time, or corrector date, it is used a wolf wheel in cooperation with two pawls. The two pawls are held by small springs against the wheel to block rotation in one direction and allow rotation in another direction. It must also be provided another pawl under the frame wheel to lock the winding of the mainspring. This locking pawl under the wheel is difficult to access and this does not allow easy disassembly including the cylinder or parts in connection with the barrel. This is generally a disadvantage of such a winding system.
    In the patent application EP 0 278 338 A1, there is described an inverter mechanism for a device for automatic winding oscillating weight of a movement of a watch. The mechanism comprises a winding wheel, which is mounted coaxially with two wolf-tooth wheels, which are arranged on either side of the winding wheel. This winding wheel carries on each of its faces at least one pawl loaded by a spring and cooperating respectively with one of the wolf-toothed wheels. This assembly is arranged in the kinematic chain of motion, interposed between the oscillating weight and the spring of the drive spring of the watch. The pawls are assigned to the transmission of the rotation of the oscillating mass, and are respectively articulated on pivoting members, which are integral with the winding wheel. Each pivoting member, which carries the pawl assigned to one of the rotational directions of the oscillating mass, also serves as an anchoring member for the spring, which loads the pawl assigned to the transmission of the other direction of rotation of the oscillating weight. said oscillating weight. However, such a mechanism with (e winding device includes too many parts, which does not facilitate the maintenance of the watch and is a drawback.
    In the patent application EP 2 221 676 A1, there is described a timepiece that includes a chronograph and a watch. The chronograph hands are driven by a first gear, which in turn drives a first resonator. The hands of the watch are driven by a second wheel independent of the first wheel, which in turn drives a second resonator. The first and second wheels are driven by a single source of energy. The energy source is a barrel rotating freely about an axis and containing a mainspring. This motor spring can be loaded by driving a wolf wheel mounted on the axis of the barrel and blocked in a direction of rotation by ratchets. However, there is not defined a unidirectional drive arrangement in connection with the barrel.
    The invention aims to overcome the disadvantages of the above-mentioned state of the art by providing a winding device with unidirectional drive arrangement, which is simple in design and allows easy maintenance or repair. disassembly of part of the movement with the barrel to be repaired.
    For this purpose, the invention relates to a winding device with unidirectional drive arrangement comprising the characteristics defined in the independent claim 1.
    Particular forms of the winding device with unidirectional drive arrangement are defined in the dependent claims 2 to 16.
    An advantage of the winding device lies in the fact that there is no need for multiple small springs and armature locking pawls to have a unidirectional drive arrangement including a winding use of a barrel spring. This is different from the winding systems of the state of the art. In this case, the winding device allows in particular to load or raise the mainspring of the barrel by an action directly on the central axis connected to the center of the barrel. The central axis can be connected to an inner end of the motor spiral spring. In a first direction of rotation of a sun gear of the device, the winding wheel connected to the central axis is rotated to raise the spring. In a second direction of rotation of the sun gear, a clutch takes place without driving the winding wheel.
    An advantage of the winding device lies in the fact that a lower portion of the sun gear comprises truncated teeth to facilitate the locking of each satellite gear in contact with at least one hook in the first direction of rotation of the pinion solar. Each satellite gear wheel is mounted with a certain clearance around an offset axis fixed on the winding wheel. This makes it possible to obtain a locking position in a first direction of rotation of the sun gear and a position of disengagement or freedom of rotation in a second direction of rotation of the sun gear.
    For this purpose, the invention relates to an assembly for reassembling at least one motor spring of at least one cylinder of a watch movement of a watch via a winding device comprising the characteristics defined in the independent claim 17.
    A particular form of the set is defined in the dependent claim 18.
    The objects, advantages and features of the winding device unidirectional drive arrangement will appear better in the following description on the basis of at least one non-limiting embodiment illustrated by the drawings in which:<tb> Figs. 1a and 1b <SEP> represent top and bottom three-dimensional views of the winding device with unidirectional drive arrangement according to the invention,<tb> fig. 2 <SEP> represents a three-dimensional view of an assembly comprising a barrel, a ratchet member and the slightly exploded winding device according to the invention, and<tb> figs. 3a and 3b <SEP> represent a partial top view of the winding device in a driving direction of rotation and an opposite direction of disengagement rotation according to the invention.
    In the following description, reference is made mainly to the operation of the winding device unidirectional drive arrangement including for winding a mainspring cylinder of a mechanical watch. However, it may also be conceivable to use such a winding device to act on one or more date discs or time indication hands.
    Figs. 1a and 1b show a winding device 1 with unidirectional drive arrangement seen from above and below. The winding device 1 comprises a sun gear 2 mounted free to rotate on a winding wheel 5, which may be a wolf-tooth wheel 15. The sun gear 2 is arranged coaxially on a surface of the winding wheel 5 As shown in FIG. 2, the sun gear 2 is mounted free to rotate about an axis or central shaft 22 not shown in FIGS. 1a and 1b, which is inserted into a tubular opening 12 of the sun gear 2 of substantially similar diameter.
    The winding device 1 further comprises at least one satellite gear 3 to mesh with a gear of the sun gear 2. The gear 3 is mounted free rotation with a certain clearance 4 about an axis or shaft offset 7 parallel to the central axis 22. This offset axis 7 is fixed perpendicularly to the winding wheel 5. The diameter of the opening of the satellite gear 3 may be between 20% and 30%, preferably close to 25% of the diameter of the offset axis 7 to define the certain set of freedom of rotation.
    The winding device 1 further comprises at least one hook 9 fixedly mounted on the winding wheel 5 to engage with a tooth of the satellite gear 3 according to the position of the toothed wheel 3 around i ' offset axis 7. In a first direction of rotation of the sun gear 2, which is the direction "a" shown in FIG. 3a in the clockwise direction, the toothing of the satellite gear wheel 3 thus engages with said hook 9 so as to be in a locking position. At least one tooth of the satellite toothed wheel 3 is also locked between two teeth of the sun gear 2. In this locking position of the planet gear 3, the rotation of the sun gear 2 in the first direction of rotation causes the wheel of reassembly 5, which can allow to assemble a mainspring of a barrel as explained below with reference to FIG. 2.
    In a second direction of rotation of the sun gear 2, which is opposite to the first direction of rotation and which is the direction "b" shown in FIG. 3b, a disengagement of the satellite wheel 3 takes place. This means that with the clearance 4 of the opening of the planet gear 3 around the offset axis 7, the rotation of the pinion in the second direction of rotation has the effect of moving the satellite gearwheel 3 away from the hook 9 Thus, the rotation of the sun gear 2 in the second direction of rotation operates freely without driving the winding wheel 5 with the free rotation of the planet gear 3.
    Preferably as shown in FIGS. 1a and 1b, two planet gears 3, 3 are provided for meshing each with the toothing of the sun gear 2. Each planet gear 3, 3 is mounted free to rotate with a certain clearance 4 about an offset axis. 7, 7 parallel to the central axis 22. The two offset axes 7, 7 are fixed on the winding wheel 5. The two satellite gear wheels 3, 3 may have an equivalent diameter. The two offset axes 7, 7 of the planet gears 3, 3 are equidistant from the central axis 22 and are preferably 180 ° apart from the central axis 22.
    With the two gear wheels satellites 3, 3 provided, the winding device 1 may further comprise two hooks 9, 9 fixedly mounted on the winding wheel 5. A first hook 9 is opposite the first gear wheel satellite 3, while a second hook 9 is opposite the second satellite gear 3. When the sun gear 2 is rotated in the first direction of rotation, at least one of the planet gears 3, 3 engages in a locking position with at least one of the hooks 9, 9. This makes it possible to rotate the winding wheel 5. In the second direction of rotation of the sun gear 2, the satellite gear wheels are disengaged so as not to drive the winding wheel 5.
    The winding device 1 preferably further comprises a frame 6 fixedly mounted coaxially on the winding wheel 5. This frame encloses in a housing, the toothed satellite wheel 3 or the satellite gear wheels 3, 3. The housing comprises an upper wall covering the planet gears 3, 3 and two side walls parallel to each other and to the line connecting the central axis 22 and the offset axes 7, 7. The distance separating each side wall is substantially similar to the diameter of the sun gear 2. Preferably, the housing is open on two opposite sides allowing a portion of each satellite wheel 3, 3 to pass. The chassis 6 comprises at least the first hook 9 to come to lock in rotation the satellite gear 3 in the first direction of rotation of the sun gear 2. According to the embodiment of FIGS. 1a and 1b, the frame 6 preferably comprises the first and second hooks 9, 9 facing respective first and second planet gears 3, 3. These two hooks 9, 9 are arranged at the periphery of the frame 6 and an inside of the frame 6. The two hooks 9, 9 are made of material with the other parts of the frame.
    As the two planet gears 3, 3 have equivalent diameters, the two hooks 9, 9 * are equidistant from the central axis 22. They are each made in the form of a curved portion towards the center. interior from one of the respective side walls of the chassis housing, which encloses the two planet gears 3, 3. The two hooks 9, 9 are arranged at 180 ° to each other relative to the central axis 22. One of the hooks is formed at the periphery of the frame 6 on one of the side walls of the housing, and the other hook is made at the periphery of the frame 6 on the other side wall. With respect to the center of the central axis 22, the two hooks 9, 9 are offset by an angle between 20 ° and 30 °, preferably 25 °, of the two planet gears 3, 3. They are angularly offset between 20 ° and 30 ° in the first direction of rotation of the sun gear 2.
    The two hooks 9, 9 in the frame 6 may also be arranged angularly offset between 20 ° and 30 ° according to the second direction of rotation of the sun gear 2 of the embodiment of FIGS. 1a and 1b. In this case, this constitutes a reverse operating arrangement of the winding device 1 described with reference to FIGS. 1a and 1b. In this reverse-working device, the first direction of rotation of the sun gear 2 of the locking position corresponds to the second direction of rotation of the sun gear 2 shown in FIGS. 1a and 1b. The second direction of rotation of the reverse-working device corresponds to the first direction of rotation of the sun gear 2 shown in FIGS. 1a and 1b with disengagement of the satellite gear wheels. The winding wheel 5 can be rotated inversely to the embodiment of FIGS. 1 a and 1 b.
    The frame 6 is fixed on the winding wheel 5, which is a wolf wheel 15, by two screws 8 inserted into openings 6a of the frame and screwed into threaded openings 5a of the winding wheel 5. The openings 6a are made in a solid part of the chassis and are arranged in a direction perpendicular to the direction of the offset axes 7, 7 of the planet gears 3, 3. The chassis 6 further comprises two passage openings 6b of the offset axes 7, 7 to keep the planet gear wheels 3, 3 locked between the winding wheel 5 and the inside of the chassis housing 6.
    The chassis further comprises an upper opening 14 for the passage of an upper portion 2a of the sun gear 2. This upper portion 2a of the sun gear 2, which exceeds the frame 6 fixed on the winding wheel 5, is capable of to be rotated in the first direction of rotation and the second direction of rotation by a not shown drive wheel. This drive wheel is connected to an oscillating weight, not shown, of a watch movement of the watch. The sun gear 2 further comprises a lower portion 2b for meshing with the planet gear or wheels 3, 3. The teeth of the lower portion 2b of the sun gear 2 are truncated to facilitate the locking of at least one tooth of the planet or toothed wheels 3, 3 between two teeth of the lower portion 2b. The locking of at least one of the planet gears 3, 3 occurs in the first direction of rotation of the sun gear 2.
    It is also noted that the winding wheel 5 comprises a central opening 16, which is of rectangular section to cooperate with a portion of the central axis 22 of complementary shape. This makes it possible to make the central axis 22 of the winding wheel 5 integral during the rotation of the winding wheel 5. A lower portion, not shown, of the central axis 22 is intended to be connected to one end of a spring motor 23 of a cylinder 21 shown in FIG. 2 for the winding of the spring during the rotation of the sun gear 2 in the first direction of rotation.
    To define certain dimensions of the components of the winding device 1, it can be expected to have an outer diameter of each toothed gear 3, 3 between 1.3 and 1.5 times less than the outer diameter of the sun gear 2. It can for example, to have an outer diameter of each satellite gear 3, 3 of the order of 3 mm and an outer diameter of the sun gear 2 of the order of 4 mm. The diameter of the tubular opening 12 of the sun gear 2 may be of the order of 1.5 mm. The diameter of each offset axis may be of the order of 0.7 mm, while the axial opening 4 of each satellite gear 3, 3 may be of the order of 0.9 mm.

A drive wheel 26 of a gear chain of the watch movement is disposed on a lower surface of the cage 21 of the barrel. This drive wheel 26 can be connected to an outer end of the mainspring 23.
    The lower portion of the central axis 22 of the device is connected to an inner end of the motor spring 23. The fixed end of the motor spring 23 is on the center side of the spiral spring. The motor spring 23 can thus be raised during the rotation of the sun gear 2 in particular in the first direction of rotation. To do this, the upper portion 2a of the sun gear 2 can mesh with a drive wheel not shown in connection with an oscillating weight of a clockwork movement.
    The assembly 10 further comprises a locking pawl 20, which is normally mounted on a bridge or mounting plate of the not shown clockwork movement. A tooth 25 of this locking pawl 20 locks in a direction of rotation the winding wheel 5, which is a wolf-tooth wheel 15.

In this case, the drive wheel in connection with an oscillating weight of a clockwork movement is arranged to mesh with the upper portions of the sun gears of the first and second winding devices. The first spring is raised in the first direction of rotation of the sun gear of the first winding device, while the second spring is raised in the first direction of rotation of the sun gear of the second winding device, which is the reverse of the first direction of rotation of the first winding device.
    From the description that has just been made, several embodiments of the winding device can be designed by the skilled person without departing from the scope of the invention defined by the claims. It can be provided more than two satellite gears in cooperation respectively with more than two hooks.
