Description

Technical Field

[0001] The present invention generally relates to a clock mechanism, and in particular, the present invention relates to a click part intended to interact with a movable part (typically a gear) to prevent the movement of the movable part in a first displacement direction and to allow the movement of the movable part in a second displacement direction.

Background Art

[0002] In the prior art, it is well known to provide an elastic section in the click part intended to apply a return force to the click part towards the blocking position of the click part, and the click part is arranged to prevent the movement of the movable part in a first displacement direction. Typically, this elastic part cooperates with a chassis or frame or a support part of the mechanism (which is part of a housing formed within the frame of the timepiece component) to apply a return force. However, there is a risk that the end of the elastic section disengages from the support part and / or its housing, and the click part no longer returns to its blocking position and becomes inoperable. Also, it may be noted that the housing and / or the support section surround the click part, which requires a significant amount of dedicated space. Finally, it can be recognized that the assembly of the click part and the associated movable part in a clock mechanism incorporating these parts can be delicate. More specifically, in particular when it involves tightening and blocking the (generally screwed) shaft of the movable part or loosening the shaft to release the blocking, the click part only blocks one direction of rotation, and at least one of the above operations (tightening and blocking or loosening to release the blocking) requires additional blocking of the movable part. This problem typically occurs when the movable part is a barrel ratchet and is attached to a barrel arbour that can normally pivot freely in one direction or the other.

Summary of the Invention

[0003] The object of the present invention is to address the above-mentioned drawbacks of the prior art. In particular, first, to enhance the safety or reliability of operation, and / or be small-sized, and / or be easy to manufacture, and / or simplify the assembly of a timepiece mechanism incorporating a click part and its related movable parts, a click part for a timepiece mechanism is provided.

[0004] For this purpose, a first aspect of the present invention is a click part for a movable part of a timepiece mechanism, for example, a toothed movable part, - a blocking position where the click part is arranged to prevent the movement of the movable part in a first displacement direction, and - a release position where the click part is arranged to allow the movement of the movable part in a second displacement direction, and is arranged to be movable between them, the click part includes an elastic section arranged to apply a return force to the click part towards the blocking position, the elastic section includes a support section arranged to form a stop joint surface together with a reference part of the timepiece mechanism, and at the stop joint surface, the support section is at least partially surrounded within the reference part, or the reference part is at least partially surrounded within the support section, and relates to a click part for a movable part of a timepiece mechanism.

[0005] According to the above implementation form, the support part is at least partially surrounded within the reference part, or the reference part is at least partially surrounded within the support part, thereby ensuring a firm and reliable cooperation between the support part and the reference part.

Such a gap can provide a large displacement stroke to the click part between the blocking position and the release position without applying a large force or a significant force. However, even with the above-mentioned gap, the support part is at least partially surrounded within the reference part, or the reference part is at least partially surrounded within the support part.

[0016] According to one embodiment, when the click part is configured at a fixed position, the click part is arranged to block the movable part in the first displacement direction. Therefore, at the fixed position, the movable part and the rest of the timepiece mechanism kinematically connected thereto are blocked and cannot move in the second (usually free) displacement direction (e.g., by pivoting), and preferably, cannot move in the displacement direction (neither in the first displacement direction nor in the second displacement direction).

Brief Description of the Drawings

[0036] Other features and advantages of the present invention will be given as non-limiting examples and will become more clearly apparent by reading the following detailed description of embodiments of the present invention shown in the accompanying drawings.

Embodiments for Carrying out the Invention

[0040] FIGS. 1 to 3 show views of a part of the timepiece mechanism as seen from above. The timepiece mechanism has a click part 10 according to the present invention and engages with the movable part 5 in various ways. FIG. 1 shows the click part 10 in the blocking (or ratcheting) position of the movable part 5, FIG. 2 shows the click part 10 in the release position of the movable part 5, and FIG. 3 shows the click part 10 in the fully fixed position of the movable part 5.

[0041] In this embodiment, the movable part 5 is a ratchet attached to the barrel. FIGS. 1 to 3 are partial views clearly showing the click part 10 and the movable part 5, in this case a part of the ratchet. Thus, FIGS. 1 to 3 are more generally partial front views of a barrel bridge forming part of the frame 6 of the timepiece components.

[0042] Specifically, the frame 6 (in this case the barrel bridge) comprises a reference part 6.1 formed by a first pin and a reference stop part 6.2 formed by a second pin. The movable part 5 typically has a ratchet tooth 5.1 fixed to the barrel center by a screw 5.2 and arranged to cooperate with the click part 10.

[0043] The click part 10 particularly - Preferably, a hub 1 that pivots around a part of the frame 6 along the axis D and is axially held, for example, by a screwed or unscrewed arbour. - A latch tongue 2 arranged on the outer edge of the hub 1. - A stop portion 8 disposed at the outer edge of the hub 1 and adjacent to the latch tongue piece 2, and - An elastic portion 4 that forms a spring arm, is connected to the hub 1, and includes a first end 4.1 adjacent to or near the stop portion and a second end 4.2 that defines a support portion 4.3 formed by the inner surface of the female oval shape, and the elastic portion 4 preferably extends along a track that is in a direction orthogonal to the radius passing through the axis D, a tangential direction, a substantially orthogonal radial direction, or a substantially tangential direction. - A blocking stop 3 disposed at the outer edge of the hub 1 and adjacent to or near the first end 4.1, and - A fixing portion 9 disposed at the outer edge of the hub 1 and adjacent to or near the blocking stop 3. The fixing portion 9 is substantially formed by a radially protruding portion separated from the hub 1 by a slot, but an elastic displacement of the fixing portion 9 with respect to the hub 1 (and / or the remaining part of the click portion 10) is possible in the radial direction or substantially in the radial direction with respect to the radius of the click portion 10 passing through the axis D.

[0044] The click portion 10 is a monolithic component or a single piece. The substantially flat portion can be manufactured and provided, for example, by additional techniques such as electrodeposition in a mold manufactured by, for example, lithography, or by microfabrication such as etching in a silicon wafer, or by molding. The click portion 10 can be made of metal (e.g., electrodeposited nickel-based and phosphorus-based metal alloys), semiconductor (such as silicon), or insulator (such as ceramic).

[0045] The following various points can be recognized in FIG. 1. - The second end 4.2 surrounds the reference portion 6.1. More specifically, the protrusion formed at the second end 4.2 enables the formation of a female oval shape having an inner surface that defines the support portion 4.3. - The gap J1 in FIG. 1, in this case, a gap with an angle in the orthogonal radial direction or tangential direction with respect to the radius passing through the axis D, exists between the reference portion 6.1 and the support portion 4.3. - Since contact can be recognized between the blocking stop portion 3 and the reference stop portion 6.2 of the frame 6, the click portion 10 is in contact with the frame 6. - The fixed portion 9 is completely disengaged from the reference stop portion 6.2. - The blocking stop portion 3 has a through hole 3.1 that allows a watchmaker to operate and / or grip the click portion 10, for example, with a pin or tweezers.

[0046] In FIG. 1, the click portion 10 occupies a blocking position arranged such that the click portion 10 blocks the movement of the movable portion 5 in the first displacement direction S1. More specifically, the latch tongue 2 is engaged between the two teeth 5.1 of the movable portion 5, and the blocking stop portion 3 is supported on the reference stop portion 6.2 of the frame 6. Thus, any movement of the movable portion 5 in the first displacement direction S1, as indicated by the arrow marked with an 'x' in FIG. 1, is blocked by the click portion 10. The blocking stop portion 3 can be arranged differently, for example, by taking the form of a simple tongue that can abut on or between the teeth 5.1 of the movable portion 5, it can be seen that it can abut on a part of the movable portion 5.

[0047] FIG. 2 shows the click portion 10 of FIG. 1 occupying the release position, and the click portion 10 is arranged to allow the movement of the movable portion 5 in the second displacement direction S2. More specifically, as described above, the click portion 10 is attached to pivotally connect to the frame 6. Thus, while the movable portion 5 moves in the second direction S2 as shown in FIG. 2, the click portion 10 can pivot counterclockwise to occupy the release position shown in FIG. 2 under the action of the force applied by the teeth 5.1 to the latch tongue 2.

[0048] While the click portion 10 is displaced towards the release position, - The blocking stop portion 3 moves away from or loses its support on the reference stop portion 6.2 of the frame 6. - The second end portion 4.2 slides on the reference portion 6.1 such that the upper section of the support portion 4.3 contacts on the reference portion 6.1 to create a gap J2 under the reference portion 6.1. During this sliding of the reference portion 6.1 at the second end portion 4.2, the click part 10 is displaced without a large force, thereby enabling a smooth operation with a minimal force so as to minimize the torque required to displace the click part 10. - The elastic part 4 is substantially bent and elastically deformed according to this configuration example so as to generate a return force of the click part 10 towards the blocking position in FIG. 1 (however, other types or configurations of the tension of the elastic part 4 are possible, such as traction, torsion, compression, or any combination of these types of stress). - Due to the counterclockwise pivoting of the click part 10, the fixed part 9 approaches the reference stop portion 6.2 but does not significantly interact. However, for example, it is possible to provide a contact part between the fixed part 9 and the reference stop portion 6.2 to limit the excessive movement of the click part 10 in the counterclockwise direction.

[0049] While the movable part 5 rotates in the second displacement direction S2, each tooth 5.1 slides on the latch tongue portion 2 and is freely disengaged by the elastic effect provided by the elastic part 4. In contrast, when the movable part 5 is fixed or displaced in the first displacement direction S1, due to the effect of the tension of the elastic part 4 and / or the cooperation between the latch tongue piece 2 and the tooth 5.1 when applicable, the click part 10 returns to the blocking position in FIG. 1.

[0050] Therefore, when the movable part 5 is a ratchet for a perfume box, it is possible to apply tension to the perfume box spring or activate the perfume box spring during displacement in the second rotation direction S2 (the configuration in FIG. 2), and this tension or this activatable state is fully guaranteed and maintained by the click part 10 when the click part 10 returns to its blocking position (the configuration in FIG. 1).

[0051] The displacement between the blocking position and the release position of the click part 10 can be recognized as being carried out without the involvement of the elastic part 4 due to the gap provided between the reference part 6.1 and the support part 4.3. As can be seen in FIGS. 1 and 2, the gap in question is substantially perpendicular to the radius passing through the axis D. In order to effectively limit the force exerted to displace the click part 10, the gap in question corresponds to at least 40%, and further at least 50%, of the displacement of the click part 10 between the blocking position and the release position. That is, at least 40%, and further at least 50%, of the displacement of the click part 10 between the blocking position and the release position is carried out without acting (being in an operable state or relaxing) on the elastic part 4.

[0052] FIG. 3 shows the click part 10 of FIG. 1 in a fixed position where the click part 10 is arranged to block the movable part at least in a second displacement direction S2. More specifically, for example, in order to facilitate the assembly operation or disassembly operation of the movable part 5 (in this case, the perfume box ratchet), it is possible to block the displacement of the movable part in at least a second displacement direction S2 (which is usually free in the typical and conventional operation of the click part 10 described in FIGS. 1 and 2).

[0053] For this purpose, in order to block the movable part 5 at least in a second displacement direction S2 (and also in a first displacement direction S1 in this embodiment), the click part 10 can be displaced to a third position different from the blocking position in FIG. 1 and the release position in FIG. 2, so that the click part 10 occupies a fixed position as shown in FIG. 3. By inserting a tool such as a pair of tweezers or a pin into the hole 3.1 of the blocking stop 3, for example, the watchmaker can manually pivot the click part 10 further in the counterclockwise direction compared to FIG. 2 so that the fixed part exceeds or passes through the reference stop 6.2 of the frame 6. In this fixed position, the reference stop 6.2 functions as a fixed stop.

[0054] Such movement is made possible by the ability of the fixed part 9 to displace elastically relative to the hub 1, and by the counterclockwise pivoting movement of the click part 10, the insertion of the stop part 8 between the two teeth 5.1 of the movable part 5 is supported simultaneously on these two teeth 5.1. In this embodiment, the fixed part 9 corresponds to an elastic notch that locks the click part 10 in the fixed position of FIG. 3.

[0055] In the fixed position, according to the exemplary embodiment of FIG. 3, it can be recognized that the stop part 8 is substantially under compressive stress and is supported by the teeth 5.1 of the movable part 5. In this configuration of FIG. 3, the elastic part 4 is further elastically deformed (compared to FIG. 2), but in any case, it can also be recognized that the fixed part 9 is arranged to apply a holding force greater than the elastic force generated by the stress of the elastic part 4.

[0056] When the click part 10 is in the fixed position of FIG. 3, the watchmaker can apply a torque, for example, a tightening torque, to screw the ratchet screw 5.2 in the second displacement direction S2, and the stop part 8 prevents the movement of the perfume box body, which is typically coupled to the movable part 5 through a non-cylindrical hole such as a square hole. In FIG. 3, the stop part 8 is arranged to contact and / or be supported by the two teeth 5.1 of the movable part 5 so as to reliably prevent the movement of the movable part 5, whereby it can be recognized that the tightening torque applied to the screw 5.2 in the second displacement direction S2 generates a force on the click part 10 that tries to pivot the click part 10 further in the counterclockwise direction.

[0057] The torque applied to the screw 5.2 in the first displacement direction S1, for example, the tightening torque, generates a force on the click part 10 that tries to pivot the click part 10 in the clockwise direction. Such a torque in the first displacement direction S1 can be applied without causing the movement of the click part 10 as long as the fixed part 9 can resist the sum of the return force of the elastic part 4 and the force applied to the click part 10 by this torque in the first displacement direction S1.

[0058] A displacement of the click part 10 in the clockwise direction from a fixed position is caused by applying a sufficiently large torque in a first displacement direction S1 to the movable part 5 or its screw 5.2, or by applying a force to the click part 10 using, for example, a tool introduced into a hole of the stop part 3. The movement in the clockwise direction has the effect of returning the fixed part 9 onto or beyond the reference stop part 6.2 (which thus forms a fixed stop here), and the click part 10 returns to the release position of FIG. 2 or the stop position of FIG. 1 under the influence of the return force of at least the still tensioned elastic part 4. In the stop position of FIG. 1, it can be recognized that the watchmaker can apply a greater torque to the movable part 5 or the screw 5.2 in the first displacement direction S1 than when the click part 10 is in the fixed position of FIG. 3. More specifically, in the stop position of FIG. 1, the click part 10 abuts against the reference stop part 6.2 that forms a distinct and firm obstacle.

[0059] Since the support part 4.3 surrounds the reference part 6.1, it can be recognized that there is no risk of seeing the support part 4.3 coming off from the reference part 6.1 (or vice versa) even while the click part 10 is moving largely between the stop position and the fixed position, and the operational safety is improved.

[0060] Also, the fixed position provided by the click part 10 can be recognized to provide a significant simplification in the assembly of the movable part 5, especially when including a movable part that can pivot freely in two rotational directions, as in the case of a perfume box ratchet.

[0061] Finally, the support part 4.3 has a closed shape (especially without an open hook), which can be recognized to significantly limit the risk of entanglement or jamming during most polishing.

Industrial Applicability

[0062] The click part for a timepiece mechanism and its manufacture according to the present invention are industrially applicable.

[0063] It will be understood that various modifications and / or improvements apparent to those skilled in the art may be applied to the various embodiments of the invention described herein without departing from the scope of the invention.

[0064] In particular, the support portion 4.3 of the click portion 10 can be made into a male shape surrounded or received within the reference portion 6.1, in which case the reference portion 6.1 has a female shape.

[0065] The support portion 4.3 of the click portion 10 can be at least partially surrounded, or surrounded, or confined, or inserted, or introduced, or coupled within the reference portion 6.1. In the illustrated embodiment, the support portion 4.3 is formed by a closed oval that completely surrounds the reference portion 6.1, but an open or partially open outer periphery can be provided, preferably the opening has a size smaller than the size of the reference portion 6.1 (the diameter of the first pin in this embodiment). Thus, even with an open shape, the reference portion 6.1 cannot pass through the opening.
