Description

Technical Field

[0001] The present invention relates to a clock module capable of being actuated at isolated moments, the clock module including a mechanism for automatically locking the operation of the module.

[0002] More specifically, the present invention relates to clock modules, such as an animation mechanism or a chiming mechanism, which are actuated at isolated moments and are required to be automatically stopped after a given period of operation.

[0003] The present invention also relates to a watch movement that includes such a watch module (e.g., a wristwatch). Background Technology

[0004] In the field of watchmaking, there are mechanisms configured to be triggered at a predetermined time or actuated on demand.

[0005] For example, in the case of a wake-up function, the sounding mechanism is configured to emit a sound at a given time. Other types of sounding mechanisms, known as minute repeaters, are those that can be actuated as needed to indicate the time verbally.

[0006] Other so-called animation mechanisms aim to animate objects through one or more movements, such as automata (active robots). The animation of automata can be programmed at a predetermined time or triggered on demand by an actuator.

[0007] Generally, these whistling or whistling mechanisms have specific drive mechanisms, such as a spring, arranged to provide the energy required for the mechanism to operate. The automaton or whistling mechanism is actuated via a gear train connected to the spring.

[0008] The mechanism can be actuated until the spring box has fully released its energy. However, some mechanisms include an automatic stop device to stop the animation or chime after a predetermined time, especially to enable the mechanism to be actuated multiple times using the same loaded spring box.

[0009] For example, document US 3460339 describes an automatic alarm mechanism including a means for locking the alarm mechanism. The automatic locking means includes a lever that engages with a rotating cam, the cam including a notch for locking the lever and preventing the mechanism from operating. The alarm mechanism also includes a means for releasing the lever to release the alarm mechanism. When the lever is released from the notch, the mechanism operates for a time corresponding to one revolution of the cam until the lever is held by the notch. The cam is driven by a drive mechanism connected thereto.

[0010] However, such a mechanism is complex to implement and takes up a lot of space.

[0011] Documents EP 2880650 and EP 2880498 describe a watch with an animation mechanism, which includes an automaton, in this case, a bird, whose animation is driven by a mainspring barrel via a gear train.

[0012] However, these documents do not describe a device for locking the mechanism before the spring barrel is fully released. Summary of the Invention

[0013] In this context, the object of the present invention is to overcome all or some of the aforementioned disadvantages by proposing a clock module that can be actuated at isolated moments, which can be automatically stopped after a predetermined operating period while maintaining a reduced size.

[0014] For this purpose, the present invention relates to a watch module for a watch movement, the watch module including a mainplate and a mechanical device capable of switching from an idle state to an operating state.

[0020] According to a specific embodiment of the present invention, when the brake lever is in the contact position, the mechanical device is in the idle position, and when the brake lever is in the away position, the mechanical device is in the working position.

[0024] According to a specific embodiment of the present invention, the rotary cam is provided with at least one notch, and the movable element is provided with a finger-like portion. When the movable element is in the locked position, the finger-like portion is inserted into the notch of the rotary cam, and when the movable element is in the retracted position, the finger-like portion is outside the notch.

[0025] According to a specific embodiment of the present invention, in the operating state of the mechanical device, the movable element remains in contact with the rotating cam.

[0026] According to a particular embodiment of the invention, the movable element is configured to automatically transition from a retracted position to a locked position after a predetermined time.

[0027] According to a specific embodiment of the present invention, the predetermined time corresponds to one revolution of the mainspring barrel.

[0043] In all the accompanying drawings, unless otherwise stated, common elements have the same reference numerals. Detailed Implementation

[0044] like Figures 1 to 3 As shown, the present invention relates to a watch module 1 for a watch movement.

[0045] The clock module 1 includes a circuit board 2, on which various components of the module 1 are disposed. The clock module 1 particularly includes a mechanical device 10 that can be triggered in an isolated moment, for example, in this embodiment, a mechanical device for animates an automaton. The mechanical device 10 is capable of transitioning from an idle state to an operating state. In the idle state, the mechanical device 10 is fixed relative to the circuit board 2, while in the operating state, the mechanical device 10 can move relative to the circuit board 2 when actuated.

[0046] The mechanical device 10 includes a gear train 20, which is configured, for example, to drive an automaton. Therefore, when the gear train 20 is actuated, the mechanical device 10 is in an operational state.

[0047] To regulate the movement of the automaton, the mechanical device 10 includes an adjuster with an adjusting pinion 19 integrally mounted on an adjusting shaft 15. The adjusting shaft 15 is rotatable to allow the adjusting pinion 19 to rotate.

[0048] There are various types of regulators; some are friction-based, while others are magnetically braked. Regulators known to those skilled in the art use friction or magnetic braking to hold the shaft in place, thereby preventing excessive rotation. Therefore, the rotational speed of the regulating shaft 15, and consequently the rotational speed of the regulating pinion 19, is controlled by the regulator.

[0049] To supply energy to the mechanical device 10, particularly to the gear train 20, the clock module 1 includes a mainspring barrel 3. The mainspring barrel 3 includes a cylindrical housing with outer peripheral teeth 6. The housing is arranged to house the mainspring inside, thereby allowing the housing and the outer peripheral teeth 6 to rotate about an axis of rotation.

[0050] The gear train 20 includes two gear pairs mounted on the machine plate: a first gear pair with a first gear 9 and a first pinion 13 arranged on the first gear 9, and a second gear pair with a second gear 11 and a second pinion (not visible in the figure) arranged below the second gear 11. The gear train 20 also includes a third gear 12.

[0051] The first gear 9, the second gear 9, and the third gear 12 are arranged sequentially. The first gear 9 is partially located below the mainspring barrel 3. The second gear 11 is partially located above the first gear 9, and the third gear 12 is located near the second gear 11.

[0052] The first pinion 13 meshes with the outer teeth 6 of the spring barrel 3, and the second pinion meshes with the first gear 9. The third gear 12 meshes with the second gear 11.

[0053] When the mainspring barrel 3 starts to rotate, it drives the first gear pair, the second gear pair, and the third gear 12. Therefore, when the mainspring barrel 3 rotates, it drives the adjusting pinion 19 and the adjusting shaft 15 by means of the gear train 20, and the adjusting pinion 19 meshes with the third gear 12.

[0054] Therefore, the rotational speed of the gear train 20 is adjusted by the regulator, thereby controlling the rotation of the automaton and thus its animation.

[0055] The clock module 1 includes a mechanism 30 for automatically locking the mechanical device 10. For this purpose, the automatic locking mechanism 30 is configured to lock the mechanical device 10 in an idle state and release the mechanical device 10 for a predetermined time in an operating state.

[0056] The automatic locking mechanism 30 includes a rotary cam 4, which is arranged to rotate about a rotation axis. A notch 5 is provided on the outer peripheral surface of the cam.

[0057] A rotating cam 4 is mounted on the spring barrel 3 and rotates integrally with it. The circular outer circumferential surface of the rotating cam 4 is located above the outer circumferential teeth 6 of the spring barrel 3. A notch 5 is formed in the outer circumferential surface and has a shape that curves inward toward the rotating cam 4.

[0058] The automatic locking mechanism 30 also includes a movable element 7, which is provided with finger-like portions 26 extending toward the rotary cam 4. The movable element 7 has a generally parallelepiped shape, and the finger-like portions 26 extend laterally in the plane of the rotary cam 4.

[0059] The movable element 7 is able to move between a locked position and a retracted position. In the locked position, the finger 26 is inserted into the notch 5 of the rotating cam 4. In the retracted position, the movable element 7 moves away from the rotating cam 4 so that the finger 26 remains outside the notch 5.

[0060] like Figure 5 As shown, during the rotation of the rotary cam 4, the movable element 7 remains in the retracted position. While the rotary cam 4 rotates together with the spring barrel 3, the ends of the finger-like portions 26 of the movable element 7 contact the outer peripheral surface of the rotary cam 4. More precisely, the movable element 7 is subjected to a restoring force that keeps it against the rotary cam 4. The source and effect of the restoring force are described in paragraphs 68 to 70 of the following specification.

[0061] With this restoring force, when the finger-shaped part 26 can be inserted into the notch 5, the movable element 7 automatically moves to the locking position, such as... Figure 6 As shown. Therefore, once the finger portion 26 faces the notch 5, the movable element 7 is no longer pushed into the retracted position by the outer peripheral surface of the rotary cam 4, and the finger portion 26 can return to the locked position, with the finger portion 26 inserted into the notch 5.

[0062] As long as the finger-shaped part 26 cannot be inserted into the notch 5 on the outer peripheral surface, the spring barrel 3 continues to rotate, and the mechanical device 10 is in operation. This restoring force enables the automatic locking mechanism 30.

[0063] In this embodiment, when the movable element 7 is in the retracted position, the mainspring barrel 3 rotates one revolution until the notch 5 faces the finger portion 26 of the movable element 7 again. This is because, since the rotating cam 4 includes a single notch 5, the mainspring barrel 3 rotates one full revolution before the automatic locking mechanism 30 stops it again.

[0064] In a variant embodiment not shown in the accompanying drawings, the rotating cam includes two or more notches, such that the mainspring barrel and the mechanism are stopped at each notch. Therefore, the mechanism operates only during the rotation of the mainspring barrel between two notches, i.e., for a period less than one revolution of the mainspring barrel.

[0065] For carrying and moving the movable element 7, the automatic locking mechanism 30 includes an intermediate rod 8 arranged on the plate 2, with the movable element 7 mounted at a first end 27 of the intermediate rod 8. The intermediate rod 8 is mounted on a second rotational pivot 21 so as to tilt and change the position of the movable element 7 from the locked position to the retracted position.

[0066] The intermediate member 8 has a curved shape and includes two generally parallel curved arms at its front end connected to the first end 27, which define an opening space. The intermediate member 8 includes a third curved arm extending rearward to form a second end 28 of the intermediate member 8. These three arms are connected by an intermediate joint 29 provided with a second rotational pivot 21.

[0067] A reset force is applied to the second end 28 of the intermediate rod 8 to keep the movable element 7 in contact with the outer peripheral surface of the rotary cam 4 via the finger portion 26. This results in a spring effect that pushes the first end 27 of the intermediate rod 8 toward the rotary cam 4 when the notch 5 of the outer peripheral surface faces the finger portion 26, thereby automatically returning the movable element 7 to the locked position.

[0068] In this embodiment, the clock module 1 includes a brake lever 14 configured to contact the adjustment shaft 15 to prevent rotation of the adjustment shaft 15. The brake lever 14 includes a first end 31 with a beak that can contact the adjustment shaft.

[0069] When the brake lever 14 is in the contact position, the mechanical device 10 is in the idle position, and when the brake lever 14 is in the away position, the mechanical device 10 is in the working position.

[0070] According to the present invention, the mechanical device 10 is stopped when the brake lever 14 is in the contact position. In other words, the mechanical device 10 is stopped by locking the adjusting shaft 15 by the brake lever 14. This is because if the adjusting shaft 15 is locked, the gear train 20 can no longer rotate because the adjusting pinion 19 holds the third gear 12.

[0071] In this embodiment, when the finger portion 26 of the movable element 7 is inserted into the recess 5 of the rotating cam 4, the mechanical device 10 will not be stopped due to the locking of the spring barrel 3. The sole function of the movable element 7, the finger portion 26, and the recess 5 is to trigger the locking of the mechanical device 10 after a predetermined time by tilting the brake lever 14 to a position in contact with the adjusting shaft 15.

[0072] In a variant embodiment, the automatic locking mechanism 30 is configured to simultaneously lock the rotation of the mainspring barrel 3 and the rotation of the adjusting shaft 15. Thus, when the finger portion 26 of the movable element 7 enters the recess 5 of the rotating cam 4, the mainspring barrel 3 is locked, and at the same time, the brake lever 14 enters a position in contact with the adjusting shaft 15 to lock the adjusting shaft 15.

[0073] The brake lever 14 is mounted to rotate about a first rotational pivot 22 so that it can tilt from a position in contact with the adjusting shaft 15 to a position away from it, allowing the adjusting shaft 15 to rotate freely. The brake lever 14 has an angled shape, and the first rotational pivot 22 is arranged on a bend at the elbow.

[0074] The automatic locking mechanism 30 also includes a first return spring 16, which rests against the first end 31 of the brake lever 14 at the contact position to maintain contact between the brake lever 14 and the adjusting shaft 15. The first return spring 16 includes a curved flexible blade that is attached to the plate on one side and is free on the other side, the free portion being bent over a first pin extending from the first end 31 of the brake lever 14.

[0075] For this purpose, the brake lever 14 includes a second end 32 on which the second end 28 of the intermediate lever 8 rests. The second end 32 of the brake lever 14 is provided with a pin 33 located in the plane of the intermediate lever 8. The pin of the brake lever 14 rests on the second end 28 of the intermediate lever 8.

[0076] Therefore, by means of pin 33, the restoring force of the first return spring 16 is transmitted to the intermediate rod 8, so that the intermediate rod 8 is in the position that the movable element 7 is pressed against the rotating cam 4.

[0077] The clock module 1 also includes an on-demand actuation device for tilting the intermediate lever 8 and thus the brake lever 14, so that the movable element 7 moves from the locked position to the retracted position and simultaneously releases the adjustment shaft 15.

[0078] For this purpose, the actuation mechanism includes a control lever 18 mounted to rotate about a third rotational pivot 23.

[0079] The control lever 18 includes a first end 35 forming an actuating actuator. The control lever 18 has an angled shape and is provided with a short section including the first end 35 and a long section, with a third rotational pivot 23 arranged in the middle of the long section. A second end 36 of the control lever 18 is located at the end of the long section.

[0080] The control lever 18 is partially mounted below the intermediate lever 8.

[0081] The control lever 18 also includes a hook 37 rotatably mounted at a second end 36 of the control lever 18. The hook 37 engages with a ratchet wheel 34 disposed near the second end 36 of the control lever 18.

[0082] The automatic locking mechanism 30 includes a second return spring 17 similar to the first return spring 16, which is configured to rest against the hook 37 to apply a force that tends to establish a relationship between the hook 37 and the ratchet wheel 34.

[0083] The control lever 18 is also connected to the intermediate lever 8 via an elongated through-hole 25 surrounding a blum stud 24 mounted on the intermediate lever 8. Therefore, when the control lever 18 pivots, it pulls the blum stud 24 of the intermediate lever 8, thereby tilting the intermediate lever 8 and moving the movable element 7 to the retracted position to release the spring box 3. Simultaneously, the intermediate lever 8 rests against the brake lever 14 to release the adjusting shaft 15, the adjusting pinion 19, and thus the mechanical device 10, which then enters the operating position.

[0084] exist Figure 4 When the user presses the first end 35, it actuates the control lever 18, which rotates in a first direction. The control lever 18 pulls the intermediate lever 8 to rotate in a second direction opposite to the first direction. The intermediate lever 8 then pushes the brake lever 14 in the first direction to release the adjusting shaft 15 according to the aforementioned method.

[0085] During the operation of the mechanical device 10 and the rotation of the mainspring barrel 3, such as Figure 5 As shown, when the user releases end 35, the control lever 18 returns to its initial position by means of the second return spring 17, and the intermediate lever 8 and the brake lever 14 remain in essentially the same position as long as the movable element 7 remains in the retracted position.

[0086] If the user does not release the control lever 18, the automatic stop cannot be triggered, and the spring box continues to rotate and drive the gear train 20.

[0087] exist Figure 6Once the finger-shaped portion 26 of the movable element 7 in the locked position can enter the recess 5, the intermediate rod 8 returns to its initial position. Since the brake lever 14 is no longer pushed by the intermediate rod 8, the brake lever 14 also returns to its contact position with the adjusting shaft 15 by the restoring force provided by the first return spring 16, thereby locking the adjusting pinion 19 and gear train 20 of the mechanical device 10.

[0088] In a variant embodiment with simultaneous locking, when the finger portion 26 is inserted into the notch 5 of the rotating cam 4, the movable element 7 also locks the rotation of the spring barrel 3.

[0089] Therefore, the mechanical device 10 of the clock module 1 is stopped after the mainspring barrel 3 has rotated one revolution, but as long as the mainspring barrel 3 has not completely released its energy, the mechanical device 10 can be set to run again by actuating the control lever 18.

[0090] The present invention also relates to a watch movement comprising the watch module 1 as described above, and a watch comprising such a watch movement.

[0091] Of course, the present invention is not limited to the embodiments described with reference to the accompanying drawings, and various modifications can be conceived without departing from the scope of the invention.
