Description

[Technical Field]

[0001] The present invention relates to the field of watchmaking, in particular to watch control devices. [Background technology]

[0002] In the prior art, controls such as push buttons are used in certain timepieces, particularly so-called "grand complication" watches, which may feature multiple functions. These push buttons are of various types, including small push buttons that are typically recessed into the middle of the watch.

[0003] Such miniature push buttons are generally very small, which saves space, especially within the case housing of these watches, and, since they do not protrude from the middle, there is no risk of accidental operation.

[0004] However, one drawback of such push buttons is that their operation to control watch functions such as setting the time, date, moon phase or calendar necessarily requires the use of a sharp actuating tool, which carries a considerable risk of damaging the watch case and consequently altering its aesthetic appearance.

[0005] In this context, it can be seen that there is a need to find a solution to overcome these shortcomings of the prior art. Summary of the Invention [Problem to be solved by the invention]

[0006] One of the objects of the present invention is to provide a control device for a timepiece that makes it possible to control the functions of the timepiece without the need for an actuation tool.

[0007] Another object of the present invention is to reduce or eliminate the need for push buttons in the watch case middle. [Means for solving the problem]

[0008] The present invention relates to a control device for a timepiece, comprising a crown movably mounted on a support for the device and intended to be fixed relative to the movement of the timepiece, said crown being movable axially relative to its longitudinal axis towards a control position, in which a rotary drive element of said crown can cooperate with a ring movably mounted in a casing ring of a control member of the device, said ring being configured to activate mechanisms of the timepiece movement that perform the timepiece functions when the crown is rotated.

[0009] In another embodiment, The casing ring comprises, on its inner peripheral wall, a zone of cooperation between the ring and the drive element, said zone comprising stop elements movably mounted within the casing ring and defining the travel path of said ring. The drive element has a free end with a connecting portion for connecting to the ring. The connecting portion extends substantially perpendicular to the outer surface of said free end. The casing ring is provided with a through hole interconnecting the inner and outer peripheral walls of said casing ring, the hole having a passage zone for said free end. The passage zone comprises a central portion configured to place the main part of the free end in said hole and an eccentric portion forming a passageway that allows the connecting portion to pass through the body of said casing ring. The ring comprises an actuating element for a pivoting element of a member adapted to actuate a mechanism that performs the functions of the watch. The control member comprises a first elastic return element configured to automatically return the ring to its rest position. The driving element is integral with the crown head.

[0010] Another aspect of the invention relates to a timepiece equipped with such a control device. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] 1 to 9, the present invention relates to a timepiece, such as a wristwatch, also called a timepiece, comprising a control device 1 for at least one function performed by a timepiece movement contained in the timepiece. Such a timepiece typically comprises a case 5, formed by a preferably circular middle 6, defining a central internal housing designed to receive a timepiece movement, the external contour of which follows the internal shape of a casing ring 29. The timepiece may be fitted with screws or clamps to hold the movement within this casing ring 29 and to hold this casing ring 29 within the middle 6 of the watchcase 5.

[0013] Such a clock movement can be mechanical or quartz. As indicated above, the movement is configured to perform at least one timepiece function, in this embodiment two timepiece functions. These functions are controlled from a control device 1 for the purpose of adjusting, correcting or activating the mechanism of the movement. It should be noted that such functions are preferably controlled independently of each other by a user from the clock control device 1. In this context, the device 1 can be considered as a control device 1 of the mechanism of the movement that performs the timepiece functions.

[0014] It will be understood that this movement is adapted to perform functions, in particular from separate mechanisms of the movement which can be kinematically coupled to one another. By way of example, each mechanism may actually provide a separate display on the watch, such as the display of the current time on the one hand and the date or moon phase on the other. The movement and its functions are controlled and / or monitored by a control device 1.

[0015] For this purpose, the control device 1 for the functioning of the movement comprises a support 3 , a crown 2 , a control member 4 and a tension member 31 .

[0016] In this device 1, the support 3, which may also be called a "support guide," is preferably a tube with a through-opening configured for a sliding guide. This tube is designed to be fixedly engaged in a radially extending through-hole in the watch middle 6. In this configuration, the support 3 is fixedly arranged relative to the watch movement.

[0017] A crown 2 is in turn movably mounted in this opening in the support 3. Such crown 2 is intended to engage with the support 3 through the middle 6 of the case 5 of the watch. This crown 2 can take the form of a push-button crown, a winding crown or any crown 2 used to operate a watch movement. This crown 2 comprises a crown head 7 and a rotary drive element 8 formed by a tubular extension integral with this head 7.

[0018] In this crown 2, the drive element 8 is located substantially within the support 3 and is configured to move or slide through an opening in this support 3. More precisely, the drive element 8 comprises a body composed of three parts: a fixed part 9a connected to the head 7 of the crown 2, an insertable part 9b that can be inserted into the through-hole 12, and a connecting part 9c configured to cooperate with the control member 4 to participate in the control of one of the timepiece's functions. In the hollow body of this drive element 8, the insertable part 9b is located after the fixed part 9a. These two parts 9a, 9b are also connected to each other by a shoulder 16 formed on the outer surface of the body of this drive element 8, as can be seen in Figures 3 to 5. The insertable part 9b consists of a main part 23a and an end part 23b. In this configuration, the main part 23a is located between the shoulder 16 and the end part 23b.

[0019] In this drive element 8, the connecting portion 9c extends perpendicular to the outer surface of the insertable portion 9b. More precisely, this connecting portion 9c extends substantially perpendicular to the zone of this surface that is included in the end 23b of the insertable portion 9b. In other words, this connecting portion 9c extends substantially perpendicular to the longitudinal axis A of the crown 2.

[0020] Thus, the insertable portion 9b and the connecting portion 9c together form a free end of the drive element 8. In other words, such free end is formed by the main portion 23a and the end portion 23b and by the connecting portion 9c. In this regard, the connecting portion 9c extends substantially perpendicular to the surface of this free end.

[0021] Also, the fixed portion 9a of the drive element 8 can be hammered into or made integral with the head 7 of the crown 2. As mentioned above, this drive element 8 has a shoulder, referenced 16 in Figures 3 to 5, which connects the fixed portion 9a and the insertable portion 9b to each other. Such shoulder 16 preferably has a flat surface. It should be noted that such surface is also substantially perpendicular to the longitudinal axis A of the crown 2.

[0022] As mentioned above, in this device 1, the rotary drive element 8 can cooperate with an actuating member 4. Such member 4 is preferably configured to be connected to a timepiece movement, in particular when the mechanism of this movement is activated to perform timepiece functions. To this end, this member 4 comprises a casing ring 29, a ring 10, at least one first elastic return element 18 and at least one movable actuating element 30.

[0023] In this member 4, the casing ring 29 can have various shapes as long as it surrounds the timepiece movement and is positioned inside the middle part 6 of the case 5. In this embodiment, this casing ring 29 is preferably substantially circular. Such a casing ring 29 has a top surface and a bottom surface, and inner and outer peripheral walls connecting these two surfaces to each other.

[0024] In this configuration, the upper surface of the casing ring 29 comprises a support zone designed to house or receive the ring 10 as part of its placement within the casing ring 29. The support zone comprises a flat surface, the side edges of which are wholly or partially raised along the entire length of the zone to ensure that the ring 10 is held and guided by this surface, in particular when the ring 10 is moved. Such surface of the support zone also comprises an open housing configured to receive the first elastic return element 18 of each of the members 4. In this configuration, the first elastic return element 18, which may be a helical spring, is arranged below the ring 10. As will be explained below, the first elastic return element 18 is designed to automatically return the ring 10 to its rest position after it has been actuated to control a timepiece function.

[0025] The casing ring 29 of this element 4 also comprises a through-hole 12 connecting its inner and outer peripheral walls 15a, 15b. Such hole 12 has a central axis B coinciding with the longitudinal axis A of the crown 2. In this configuration, the geometry of this hole 12 and its position within the casing ring 29 are such that a drive element 8 can pass through it. This hole 12 comprises at least one passage zone 24a, 24b for the free end of the drive element 8 to control at least one function of the timepiece.

[0026] 6a, 6b, and 7, the through hole 12 has first and second passage zones 24a, 24b, each configured to control a timepiece function. In other words, these two passage zones 24a, 24b allow such a through hole 12 to be structurally configured to control two timepiece functions. In this regard, each passage zone 24a, 24b comprises a central portion 26 configured to position the main portion 23a, and thus the free end, of the insertable portion 9b in the through hole 12, and an eccentric portion 25a, 25b configured to pass the connecting portion 9c through the through hole 12. The eccentric portions 25a, 25b form a passage that allows the connecting portion 9c to pass through the body of the casing ring 29 to the cooperating zone 11 defined in the inner peripheral wall 15b, which will be described later. In this regard, it will be understood that the two passage zones 24a, 24b share the same central portion 26. In other words, the central portions 26 of the two zones 24a, 24b coincide. In this configuration, central portion 26 extends a distance from outer peripheral wall 15a to inner peripheral wall 15b of casing ring 29 that is substantially shorter than the length of main portion 23a of insertable portion 9b. A "substantially shorter" distance means that the distance is "strictly shorter" or "substantially shorter" than the length of main portion 23a.

[0027] The casing ring 29 also comprises a through-opening 17 forming a housing for receiving at least one pivoting element 14, such as a rocker, that can be actuated by the ring 10 to interact with the mechanism of the movement that performs a function. The casing ring 29 comprises a second elastic return element and a retaining element arranged in the housing and intended to cooperate with the pivoting element 14, in particular to set it in an initial rest position. The pivoting element 14 consequently alternates between an initial position and an operating position in which a part of the element 14 protrudes from the inner peripheral wall 15b of the casing ring 29 to interact with the mechanism that performs the controlled function. The positioning of the pivoting element 14 in the operating position is controlled by the ring 10, in particular by an actuating element 30 of the ring 10. It should be noted that the pivoting element 14 moves from the operating position to the initial position under the action of the second elastic return element, which causes the pivoting element 14 to move in the direction opposite to the direction intended to set the pivoting element 14 in its operating position, until the element 14 abuts against the retaining element.

[0028] As mentioned above, the casing ring 29 comprises a cooperation zone 11 between the rotary drive element 8 and the control member 4. More precisely, this zone 11 is the location where the coupling portion 9c of the drive element 8 cooperates with the coupling element 13 of the ring 10 in order to move the ring 10 inside the casing ring 29. Such a zone 11 is contained in the inner circumferential wall 15b of the casing ring 29. This zone 11 includes in particular the portion of this inner circumferential wall 15b where the through-holes 12 open. In this configuration, the zone 11 has stop elements 28 which can cooperate with the coupling element 13 of the ring 10 to define the travel path of the ring 10 movable inside the casing ring 29.

[0029] In this device 1, the ring 10, also known as the "movable ring", has a shape configured to ensure its positioning and movement within the support zone of the casing ring 29. In this embodiment, this ring 10 has a substantially circular shape. This ring 10 has a top surface and a bottom surface, and inner and outer sides.

[0030] As mentioned above, the ring 10 comprises the at least one actuating element 30, the connecting element 13 and at least one connecting element for connecting to the first elastic return element 18. The ring 10 comprises as many actuating elements and connecting elements 30 as the control device 1 is able to control functions. More precisely, if the control device 1 is configured to control a single function, the ring 10 comprises a single actuating element 30, a single connecting element and a single connecting element. In this regard, the casing ring 29 comprises a single first elastic return element 18. If the device 1 is configured to control two functions, the ring 10 comprises two actuating elements 30, a single connecting element 13 and two connecting elements capable of cooperating with two different first elastic return elements 18, as shown in Figures 1 and 2.

[0031] In the ring 10, the actuating element 30 of the pivoting element 14 is included on the outer side of the ring 10. The actuating element 30 is configured to extend toward an area 27 of the housing that accommodates the pivoting element 14, said area being located near the pivoting element 14 to be actuated. In other words, the actuating element 30 extends substantially perpendicularly toward the area 27 on the opposite side of the pivoting element 14. It will be understood that the location of the actuating element 30 in the area 27 of the housing allows the actuating element 30 to be positioned in close proximity to the pivoting element 14. This positioning allows the actuating element 30 to actuate the pivoting element 14 so that the pivoting element 14 can move from its initial position to its actuated position. The actuating element 30, protruding from the outer side of the ring 10, is formed by a first portion substantially perpendicular to this plane and a second portion substantially parallel to this same plane, and, due to the portions being substantially perpendicular to each other, has a shape substantially similar to that of the letter "L."

[0032] The ring 10 also includes a connecting element for connecting to a first elastic return element 18 disposed within a housing included in the support zone of the casing ring 29. The connecting element is located on the bottom side of the ring 10. It extends substantially perpendicularly from the bottom side to the bottom of the corresponding housing that includes the first elastic return element. In other words, the connecting element is partially disposed within the housing in the support zone, between the first end of the first elastic return element 18 and the wall of the housing. The connecting element has a shape configured to apply or exert a restraining force on the first end with which it is in contact, and the second end of the first return element 18 can contact or be supported by a support wall of the housing located opposite the connecting element. It will be understood that in this configuration, since the connecting element is partially disposed within the housing, it can move within the confines of the housing to compress the return element 18 when the ring 10 is moving.

[0033] 2, 8 and 9, the connecting element 13 of the ring 10 is located on the inner side of said ring 10. This element 13, which is preferably integral with the body of the ring 10, forms on this surface a relief that is substantially polygonal in shape, this shape being particularly suitable for achieving an optimum connection to the connecting part 9c of the drive element 8.

[0034] As mentioned above, the device 1 also includes a tensioning member 31 configured to improve the cooperation between the coupling portion 9c and the coupling element 13 in order to ensure optimal movement of the ring 10 in the support zone of the casing ring 29. More precisely, such member 31 serves to maintain contact established between the coupling portion 9c and the inner side of the ring 10, and thus the surface of the cooperation zone 11, in order to ensure that the coupling between the coupling portion 9c and the coupling element 13 is achieved as part of the movement of the ring 10 within the casing ring 29. Such tensioning member 31 comprises a spring 19 freely mounted in a cylindrical housing defined by the fixed portion 9a of the drive element 8 fixed to the crown head 7, and a compression portion 20 of this spring 19 supported on a stem 21, for example the winding / setting stem of a watch. This compression portion 20 comprises a shoulder 22 forming a support zone for a first end of the spring 19, the shoulder 22 being located on the opposite side of the crown head and forming another support zone capable of cooperating with a second end of the spring 19.

[0035] It will be understood that in this embodiment, such a control device 1 allows the implementation of a method for controlling a timepiece, in particular a method for controlling at least one function of the timepiece. To this end, the method provides a process for operating the device 1 to control a timepiece function. During this process, the crown 2 is manipulated from its initial position to a control position in which the crown 2, in particular the crown head 7, is positioned closest to the middle 6. During this manipulation, the crown 2 is moved axially from its initial position toward the through-hole 12 by compressing the spring 19 disposed between the head 7 of the crown 2 and a compression element 20 included in the crown 2. When the free end of the drive element 8 of the crown 2 is adjacent to or in contact with the outer peripheral wall 15a of the casing ring 29 of the control member 4, the crown 2 is rotated to insert this free end into at least one passage zone 24a, 24b of the through-hole 12. As previously mentioned, in this embodiment, the through-hole 12 can have two passage zones 24a, 24b for controlling two different timepiece functions. In this connection, in order to select a passage zone 24a, 24b for the function to be controlled and to insert its free end into this zone, the crown 2 is rotated in a first direction until the shoulder 16 connecting the fixed part 9a and the insertable part 9b of the drive element 8 abuts against the outer peripheral wall 15a of the casing ring 29. When this shoulder 16 abuts against the outer peripheral wall 15a, the crown 2 is operated in a second direction opposite / reverse to the first direction and is set in its control position for cooperation with the connecting element 13 of the ring 10. In the latter configuration, this crown 2 is consequently in the control position and can cooperate with the connecting element 13 of the ring 10 via the connecting part 9c of the drive element 8 of the crown 2. It should be noted that in this control position, the connecting part 9c of the drive element 8 of the crown 2 is held in abutment against the inner peripheral wall 15b of the casing ring 29 by the action of the spring 19, which exerts an elastic return force on the crown 2. It should be noted that the control position is the position in which the drive element 8 and thus the free end of the crown 2 engages in the through hole 12 and / or the free end cooperates with or is connected to the ring 10. In other words, it is the position in which the main part 23a of the free end of the crown 2 is located in the through hole 12.

[0036] If the crown 2 is then rotated in a second direction of rotation, the ring 10 moves within the support zone of the casing ring 29 as a result of the cooperation between the connecting portion 9c of the drive element 8 of the crown 2 and the connecting element 13 of the ring 10. This movement takes place until the connecting element 13 comes into contact with a corresponding stop element 28 of the cooperation zone 11. This movement of the ring 10 generates, via its connecting element, a tension in the first elastic return element 18, which is arranged in a housing defined within the support zone below this ring 10. During this movement, the actuating element 30 of the ring 10 actuates the corresponding swivel element 14 by changing the position of this swivel element 14 towards an actuated position, in which a part of this element 14 protrudes from the inner circumferential wall 15b of the casing ring 29 and interacts with the corresponding mechanism of the movement to perform the controlled function. When the crown 2 is then operated, the ring 10 is automatically placed in its rest position by the action of the first elastic return element 18, which returns to its rest shape. By placing the ring 10 in its rest position, the pivoting element 14 is automatically placed in its initial position, since it is no longer constrained by the actuating element 30 of the ring 10.

[0037] The method can then include a process of stopping the device 1, during which the crown 2 is operated to return from its control position to its initial position. In this connection, the crown 2 is rotated in a first direction until the connecting portion 9c of the drive element 8 is positioned opposite the eccentric portions 25a, 25b of the corresponding passage zones 24a, 24b of the through-hole 12 of the casing ring 29. In such a configuration, the spring 19 arranged in the crown 2 resumes its rest shape, causing an axial movement of the crown 2, as a result of which the free end of the drive element 8 is withdrawn from said passage zones 24a, 24b and said crown 2 is automatically positioned in its initial position.

[0038] It should also be noted that in this specification, "substantially vertical" or "substantially vertically" means "strictly vertical" or "essentially vertical."

[0039] The invention has been described above by way of example only. It goes without saying that modifications can be made without departing from the scope of the invention as claimed. By way of example, it will be understood that the control device 1 can be configured to perform more than the two functions described herein in this embodiment, in particular by comprising a casing ring 29 in which the through-hole 12 comprises three or more passage zones for the free ends of the drive elements 8 of the crown 2.
