Description

[Technical Field]

[0001] The present invention relates to a timepiece part intended to receive a driven element. The invention also relates to an assembly including such a part and an element mounted on or driven into the part. The invention further relates to a movement including such a part or such an assembly. The invention finally relates to a timepiece, in particular a miniature timepiece, including such a movement or such an assembly or such a part. [Background technology]

[0002] The assembly process of some gears, and in particular escape wheels, characterized by being manufactured by the LIGA process from a nickel-based alloy constitutes an improved method in terms of robustness and reproducibility.

[0003] The prior art documents disclose numerous elastic structural shapes adapted to enable the hammering of normally fragile timepiece parts onto a shaft. This type of structure is usually adapted with the objective of minimizing the hammering force while maximizing the clamping force on the shaft. Such structures include, for example, elastic arms designed to be activated by bending during hammering of the shaft.

[0004] For example, U.S. Patent Nos. 5,629,999, 5,749,162, 5,799,173, and 5,849,186 each disclose a spiral spring ball and a gear including a resilient structure with multiple resilient arms embedded in only one end of the ball. This type of structure, characterized by an opening or a discontinuous contour, has proven to be particularly fragile and brittle. Furthermore, the expected clamping force is low.

[0005] Alternatively, this type of resilient structure may have, for example, a closed or continuous contour. For example, U.S. Patent No. 5,629,999 and U.S. Patent No. 5,629,999 disclose a bristle pin with three or four resilient arms projecting inward from a first main opening intended to receive the shaft so as to contact the shaft during the driving operation. These three- or four-protruding bristle pins each include a second opening that opens toward the first main opening. The second opening is adapted to maximize the effective length of the resilient arms and defines a point at which the resilient arms are embedded as far as possible from the center of the first main opening. During the driving operation of the shaft, the support point on the shaft is displaced radially relative to the shaft's geometric axis due to the bending of each of the resilient arms. The clamping force is primarily generated by the stiffness of each of the arms, which is determined here by the height and thickness of the bristle pin. This limits the scope of this type of shape.

[0006] Patent document 6 discloses a resilient structure including second openings in the form of slots that open towards the first opening intended to receive the shaft. The extent of these slots, together with a third opening in the form of a portion of a circular ring, defines the extent of resilient arms designed to come into contact with the shaft. In other words, the area in which the resilient arms are incorporated is not exclusively defined by the third opening, but by the second opening.

[0007] The problem of out-of-roundness that tends to occur with this type of elastic structure is disclosed in Patent Document 7. To solve this problem, this patent proposes the use of an elastic structure similar to that disclosed in Patent Document 6. The elastic structure described in the escape wheel also includes a second opening in the form of a slot, opening toward the first opening intended to receive the shaft. The extent of these slots, together with a third opening in the form of a portion of a circular ring, defines the extent of the elastic arm designed to contact the shaft. To minimize deformation of the outer edge of the gear, the elastic structure further includes a fourth opening in the form of an elliptical slot with multiple different extents, located at the contact point between the second and third openings and the escape wheel teeth. Here, the fourth opening is designed to deform and thereby absorb the deformation caused by the deformation of the elastic arm. The aesthetics of the escape wheel are determined by the shape of the elastic structure, which here occupies the majority of the escape wheel plate. This type of elastic structure is difficult to replace with a given aesthetic timepiece component, regardless of its dimensions. [Prior art documents] [Patent documents]

[0017] A first embodiment of a timepiece 400 according to the invention will now be described with reference to figures 1 to 4c. The timepiece is for example a small timepiece, such as a wristwatch.

[0018] The watch includes a watch movement 300. The watch movement may be mechanical, in particular automatic. Alternatively, the movement may be electronic.

[0019] The movement comprises an assembly 200 including a watch element 20 and a first watch component embodiment 100, the watch element 20 being mounted on the watch component 100 and in particular driven.

[0020] The watch part comprises a first opening 1 intended to receive the element 20 when the element 20 is driven into the opening.

[0021] The element, in particular the part of the element intended to be hammered into the timepiece component, may be made of a brittle material, in particular ceramic or ruby. The element part may be a shaft, in particular a cylindrical or substantially cylindrical shaft.

[0022] In the first embodiment, the part 100 is an escape wheel. The part 100 may be another type of gear, or the part 100 may be of another type. In the first embodiment, the escape wheel 100 may have an outer diameter D6 of the hub 6 that is advantageously smaller than D9 / 2, or smaller than D9 / 3, or smaller than D9 / 4, where D9 is the head diameter of the teeth 9 arranged on the outer edge 8 of the gear 100.

[0023] The watch parts and components are shown in the figures in cross section, in particular in a cross section on a plane perpendicular to the direction or axis A1 along which the component is driven into the part.

[0024] The watch part 100 comprises a first opening 1 intended to receive the element 20 when the element 20 is driven into the first opening. An axis A1 is centered in the first opening. The watch part 100 comprises at least two structures 10 intended to receive elements.

[0025] Each receiving structure is - intended to come into contact with the member and at least substantially with respect to the axis A1 Right-angle radial a receiving element 4b extending to a first connecting element 4c extending from the first end of the receiving element at least substantially radially relative to the axis A1; a second connecting element 4d extending from the second end of the receiving element at least substantially radially relative to the axis A1; - at least substantially relative to axis A1 Right-angle radial a first elastically deformable element 4a extending from - at least substantially relative to axis A1 Right-angle radial a second elastically deformable element 4a' extending from Equipped with.

[0026] The first connecting element mechanically connects a first end of the receiving element to the first elastically deformable element, and the second connecting element mechanically connects a second end of the receiving element to the second elastically deformable element.

[0027] The receiving element 4b comprises a bearing area extending between the two ends 1a, 1b of the receiving element 4b, in particular from the first end 1a to the second end 1b. The bearing area is intended to come into contact with the member 20, in particular with the shaft of the member. These ends are defined by the intersection of the first opening 1 and the second opening 2, 2". The bearing area may comprise a single continuous surface. Alternatively, the bearing area may comprise several surfaces, in particular several elongated surfaces, in particular surfaces extending parallel to the axis A1. The receiving element thus comprises at least one surface or one contact point intended to come into contact with the member. The receiving element 4b preferably comprises a first linear bearing area extending parallel to the axis A1, for example at the level of the first end 1a of the receiving element 4b, and a second linear bearing area extending parallel to the axis A1 at the second end 1b of the receiving element 4b. The first and / or second bearing area therefore have a straight or substantially straight shape.

[0028] At rest, i.e., when no member is introduced into the opening, the first opening 1 has a substantially cylindrical shape with a diameter D1, which is the diameter of the largest diameter cylinder that can be inscribed in the opening. The axis A1 is defined as the axis of rotation of the largest diameter cylinder. In this sense, the first opening 1 is centered on the axis A1.

[0029] When member 20 is driven, the geometric axis A2 of the member, in particular the axis of symmetry or rotation A2 of the shaft of member 20, is designed to be aligned or substantially aligned with the geometric axis A1 of structure 10.

[0030] The timepiece part may include three structures 10 intended to receive elements. The bearing structures advantageously constitute a three-fold rotationally symmetric assembly. For this reason, only one bearing structure will be described in detail here. The other bearing structures are inferred from the described bearing structure in rotation about axis A1. Elements of other structures similar or having the same function as elements of the described bearing structure are identified by the same reference numerals followed by an "'" or "".

[0031] The parts are advantageously adapted so that when the member 20 is guided into the first opening, the elastically deformable element is biased mainly in bending, and / or the connecting element is biased mainly in compression, and / or the receiving element is biased mainly in bending.

[0032] The part advantageously comprises at least second openings 2, 2', 2" extending substantially radially with respect to the axis A1 and opening to the first openings. Each second opening also radially limits two receiving elements of two adjacent receiving structures and / or separates a first connecting element from a second connecting element of two adjacent receiving structures. The second openings 2 are for example slots extending radially from the first opening 1 with respect to the axis A1. The depth of the slot (measured radially with respect to the axis A1) is for example 0.05 mm (measured radially with respect to the axis A1). Right-angle radial greater than twice the width of the slot (measured at the

[0033] The second openings 2, 2', 2" are preferably U-shaped, i.e. with a rounded bottom, V-shaped, i.e. with a linear or substantially linear bottom, or battlemented, i.e. with a flat bottom. The second openings 2, 2', 2" are preferably inscribed in a cylinder of minimum diameter D2, wherein diameter D2 is greater than or equal to 1.1 and less than or equal to 3 times diameter D1.

[0034] (Across axis A1 Right-angle radial The width d of the opening (measured at 2×d) is preferably given by the equation 2×d=α×D1, where α is greater than or equal to 0.17 and less than or equal to 0.7.

[0035] Together with the first and second openings, the third openings 3, 3', 3'' (which do not open into the first opening 1 or into the second opening) make it possible to define the shape of the receiving structure.

[0036] The third opening is mainly at the height of the first diameter D3a relative to the axis A1. Right-angle radial to or substantially Right-angle radial a first opening 3a extending to the axis A1 at a height of a second diameter D3b; Right-angle radial to or substantially Right-angle radialand a third opening 3c extending radially or substantially radially relative to the axis A1 from the first portion to the second portion, in particular from one end of the first portion to one end of the second portion.

[0037] The second diameter D3b is smaller than the first diameter D3a. For example, the diameters D3b and D3a may be related or substantially related by the following equation: 2×D3b=D1+D3a

[0038] For example, the first portion 3a may extend over an angle of 1.5×π / N about the axis A1, where N is the number of receiving structures.

[0039] For example, the second portion 3b may extend over an angle of 0.8×π / N about the axis A1, where N is the number of receiving structures.

[0040] Alternatively, the first and second portions 3a, 3b may extend over the same or substantially the same angle about the axis A1.

[0041] The first and / or second elastically deformable element advantageously has a beam structure integrated at only one end thereof at the level of the hub or at the level of the second arm 5 connected to the hub.

[0042] The part is advantageously at least substantially Right-angle radial and a first portion 3a extending at least substantially Right-angle radial and a third portion 3c extending at least substantially radially relative to the axis A1.

[0043] The first portion 3a preferably defines an elastically deformable element 4a radially relative to the axis A1, and / or the second portion 3b preferably defines a receiving element 4b″ radially relative to the axis A1, and / or the third portion 3c preferably defines a receiving element 4b″ radially relative to the axis A1. Right-angle radial 4d″。 4d″ defines a connecting element.

[0044] The shape of these openings is as follows: a first part 4a of the arm 4, - the second part 4c of the arm 4, a third portion 4b of the arm 4, and the fourth part 4d of the arm 4 This makes it possible to define an arm 4 comprising:

[0045] The first portion 4a is embedded in a second arm 5, which extends radially or substantially radially relative to the axis A1 from the hub 6, in particular from the inner surface 61 of the hub. Embedded here means defined by two openings 3, 3', in particular portions 3a, 3b' and 3c'. More specifically, the cross section of the arm 4 at the height of the first portion 4a is defined by diameters D3a, D3b and by the width L of portions 3a, 3b' (measured radially relative to the axis A1). The first portion 4a constitutes, for example, the above-mentioned second elastically deformable element.

[0046] The second portion 4c extends from the end of the first portion 4a in a radial or substantially radial direction relative to the axis A1. The second portion 4c is, for example, defined by the portion 3b' of the third opening 3' and the opening 2. The second portion 4c constitutes, for example, the above-mentioned second connecting element 4c. The portion 4c is curved.

[0047] The third portion 4b is spaced from the end of the second portion 4c relative to the axis A1. Right-angle radial to or substantially Right-angle radial The third portion 4b is defined, for example, by the portion 3b' of the third opening 3' and the opening 1. The third portion 4b constitutes, for example, the above-mentioned receiving element 4b. The cross section of the arm 4 at the height of the third portion 4b is defined by the diameters D3b and D1 of the portion 3b and the width L (measured radially) of the portion 3b.

[0048] The fourth portion 4d extends from one end of the third portion 4b in a radial or substantially radial direction relative to the axis A1. The fourth portion 4d is defined, for example, by the portion 3c' of the third opening and the opening 2'. The fourth portion 4d constitutes, for example, the first connecting element 4d described above.

[0049] The fourth portion 4d is advantageously joined to the first portion 4a' of the adjacent arm 4', which first portion 4a' of the adjacent arm 4' advantageously constitutes the above-mentioned first elastically deformable element 4a'. Thus, in a preferred embodiment, the same elastically deformable element 4a constitutes the first and second elastically deformable elements of two adjacent receiving arrangements.

[0050] When assembling the piece 20, the receiving elements 4b, 4b' and 4b" are adapted to be moved relative to the axis A1. For this purpose, the shaft of the piece 20 comprises a portion 20a whose shape, in particular its diameter D20a, is larger than the shape, in particular the diameter D1, of the first opening 1. For this purpose, the insertion of the portion 20a into the opening 1 causes a movement of the bearing area relative to the axis A1. More specifically, the bending of the elastic arms 4, 4', 4" combined with the widening of the second openings 2, 2', 2" advantageously allows the bearing area to be displaced in radius and in relation to the axis A1 without deformation of the remaining timepiece part 100, in particular without deformation of the hub 6. Right-angle radial This causes the receiving element to move in the direction.

[0051] The clamping force on the shaft 20 is advantageously determined primarily by the shape of the second openings 2, 2', while the stress applied to the hub 6 is minimized by the structure of the first arm 4, i.e., by the shape of the two third openings 3, 3'.

[0052] In the first embodiment shown in Figures 1 to 4, all receiving structures 10 have three-fold symmetry with respect to axis A1. Thus, all receiving structures 10 have three second openings 2, 2', 2" and three first arms 4, 4', 4" evenly distributed around geometric axis A1.

[0053] This type of arrangement makes it possible, for a given opening geometry, to maximize the number of resilient arms while minimizing their stiffness, and therefore to minimize stresses in the material from which the arms are made. This type of arrangement makes it possible to minimize stresses in the receiving structure 10 for a given clamping force of the member 20 on the shaft.

[0054] Figures 4a, 4b and 4c show the distribution of stresses in the receiving structure 10 during the step of assembling the member 20 to the watch part 100. Figure 4a shows the watch part in a rest state, i.e. not biased by contact with the watch part. Here, the structure 10 is completely black, which indicates that the stress level of the material that makes up the structure 10 is zero.

[0055] FIG. 4b shows that as the shaft 20 is guided into the opening 1, it expands from the diameter D20 to the diameter D20a, so that a part of the watch part 20 moves the bearing elements 4b, 4b″ and 4b″ radially and radially relative to the axis A1. Right-angle radial 1 shows an intermediate assembly stage in which the hub 6 comes into contact with the receiving elements 4b, 4b", and 4b" in order to move it in the direction of the arrow A. The white cross-hatching represents the level of stress caused by the widening of the three second openings 2, 2', 2" and by the bending of the three first arms 4, 4', 4". It is noted here that the level of stress in the hub 6 is not affected by the elastic deformation of the openings 2, 2', 2" and arms 4, 4', 4".

[0056] Figure 4c shows the watch part 100 when the member 20 is fully inserted. It can be seen that, despite the propagation of stresses in the arm 4, the hub 6 is not or only not significantly affected. As a result, the hub is not deformed, much less the periphery or outer edge of the gear.

[0057] Thus, structure 10 allows assembly of member 20 within part 100 without unnecessary deformation of the hubs, arms, or outer edges of the part.

[0058] A second embodiment of a timepiece 400 according to the invention will now be described with reference to Figure 5. The timepiece is a small timepiece, for example a wristwatch.

[0059] The watch includes a watch movement 300. The watch movement may be mechanical, in particular automatic. Alternatively, the movement may be electronic.

[0060] The movement comprises an assembly 200 including a watch element 20 and a second watch component embodiment 100, the watch element 20 being mounted on the watch component 100 and in particular driven.

[0061] The second embodiment of the timepiece or timepiece part differs from the first embodiment of the timepiece or timepiece part only in that, for example, the timepiece part has only two bridge structures.

[0062] The assembly formed by the two receiving structures preferably has two-fold rotational symmetry.

[0063] Furthermore, in the second embodiment, the timepiece component does not necessarily have to have the second arm 5. In this case, the first arm 4 may be mechanically connected directly to the hub 6.

[0064] A third embodiment of a timepiece 400 according to the invention will now be described with reference to Figure 6. The timepiece is a small timepiece such as a wristwatch.

[0065] The watch includes a watch movement 300. The watch movement may be mechanical, in particular automatic. Alternatively, the movement may be electronic.

[0066] The movement comprises an assembly 200 including a watch element 20 and a third watch component embodiment 100, the watch element 20 being mounted on the watch component 100 and in particular driven.

[0067] The third embodiment of the timepiece or timepiece part preferably differs from the first embodiment of the timepiece or timepiece part only in that, for example, the timepiece part has four bridge structures.

[0068] The assembly formed by the four receiving structures preferably has four-fold rotational symmetry.

[0069] Furthermore, the third embodiment of the timepiece or timepiece component differs from the first and second embodiments of the timepiece or timepiece component in that the third opening is double.

[0070] In the third embodiment, receiving structure elements that are similar or have the same function as elements of the receiving structure of the first or second embodiment are identified by the same reference numerals with the prefix "1" added.

[0071] Each receiving structure 110 includes a first resilient arm 14 including a first portion 14a embedded in a second arm 15 extending from a hub 16 in a substantially radial direction relative to the axis 1A1 of the first opening 11, where embedded means that each is at least partially embedded in the second arm 15 relative to the axis 1A1. Right-angle radial More specifically, the term "integrated" here means that the two third openings 13a, 13b' extend in the direction perpendicular to the axis 1A1. Right-angle radial The cross section of arm 14 at the height of first portion 14a is defined by diameters D13a, D13b and width L of portions 113a, 113b' (measured radially relative to axis 1A1). Furthermore, portions 113b' and 113b' of third opening 13b', together with first and second openings 11a and 12', allow for the definition of portions 14b, 14c, and 14d of arm 14. Arm 14 thus has a curved arm shape.

[0072] In the third embodiment shown in FIG. 6, all receiving structures 110 have four-fold rotational symmetry with respect to axis 1A1, and the four first arms 14, 14', 14", 14* are evenly arranged around geometric axis 1A1. The portions 14a, 14a', 14a", 14a* are driven into each of the second arms 15, 15', 15", 15*. In this embodiment, the portions 14b, 14b', 14b", 14b* of each of the arms 14, 14', 14", 14* are assembled into the portions 14a, 14a', 14a", 14a* of each of the arms 14, 14', 14", 14* via the portions 14c, 14c', 14c", 14c*, respectively. In other words, the arms are interleaved with each other.

[0073] Regardless of the embodiment or variant embodiment, the part may include two, three, or four structures intended to receive members, and / or the receiving structures may form an assembly with N-fold rotational symmetry, where N=2 or N=3 or N=4.

[0074] Regardless of the embodiment or variant, the timepiece part is preferably adapted so that, when the member is guided into the first opening, the elastically deformable element is biased mainly in bending and / or the connecting element is biased mainly in compression and / or the receiving element is biased mainly in bending.

[0075] Regardless of the embodiment or variant, the timepiece part preferably includes second openings extending at least substantially radially relative to the axis and opening relative to the first opening, each second opening being adapted to receive two receiving elements of two adjacent receiving structures. Right-angle radial and / or each second opening separates a first connecting element from a second connecting element of two adjacent receiving structures.

[0076] Regardless of the embodiment or variant, the timepiece part preferably comprises one elastically deformable element constituting the first and second elastically deformable elements of two adjacent receiving structures.

[0077] Regardless of the embodiment or variant, the first elastically deformable element and / or the second elastically deformable element preferably includes a beam structure integrated into only one of its ends.

[0078] Regardless of the embodiment or variant, the timepiece part is preferably at least substantially Right-angle radial a first portion extending at least substantially relative to the axis; Right-angle radial and a third portion extending at least substantially radially relative to the axis.

[0079] Regardless of the embodiment or variant, the first part preferably defines an elastically deformable element radially relative to the axis, and / or the second part preferably defines a receiving element radially relative to the axis, and / or the third part preferably defines a connecting element radially relative to the axis. Right-angle radial It is defined as

[0080] Regardless of the embodiment or variant, a first circular cylinder having a first diameter is inscribed in the first opening, and a second opening is inscribed in a second circular cylinder having a second diameter, the second diameter being between 1.1 and 2.5 times the first diameter.

[0081] Regardless of the embodiment or variant, the receiving element preferably comprises at least one surface or one contact point intended to come into contact with the member.

[0082] Regardless of the embodiment or variant, the first opening is inscribed in a first circular cylinder having a first diameter, and the second opening is inscribed in a second circular cylinder having a second diameter, the second diameter varying between 1.1 and 2.5 times the first diameter.

[0083] Regardless of the embodiment or variant, the watch component may be manufactured by electroforming, LIGA type processing, or photolithography and deep corrosion processing.

[0084] Regardless of the embodiment or variant, the watch parts may be made of brittle material or Ni or NiP or Si or diamond or quartz.

[0085] Regardless of the embodiment or variant embodiment, the watch part may include a hub 6 having an outer diameter of less than 2 mm, or less than 1.5 mm, or less than 1.2 mm, and the receiving structure is mechanically connected to the hub, to the interior of the hub, i.e., to the surface facing the interior of the hub.

[0086] Cross sections of the structure are shown for the various embodiments. These cross sections are preferably identical in all the various cross-sectional planes perpendicular to the axes A1, 1A1 and may be oriented in a similar manner. In any case, the cross sections may also extend along the axes A1, 1A1. In particular, the cross sections may be rotated along the axes A1, 1A1, so that a helical shape is formed.

[0087] For this reason, the above-mentioned timepiece solutions comprise elastic structures designed to receive elements such as shafts, and these structures are characterized by being particularly compact: for example, the elastic structure can be located in the center of the timepiece, in particular in the gear wheel, and can be supported by a hub with a small diameter.

[0088] Furthermore, this type of structure advantageously makes it possible to avoid deformation of the external shape of the timepiece part, such as the outer edge, or deformation of the arms connecting the hub to the outer edge during the striking of the part. Furthermore, due to its compactness, this structure does not affect the aesthetics or shape of the main parts of the part, in particular the plates of the gear. In particular, this structure does not affect the aesthetics or shape of the arms connecting the hub to the outer edge of the gear. For this reason, this type of structure is advantageously implemented in parts of a given design, in particular in gears.

[0089] The above-mentioned components are particularly suitable for materials with no or little plastic zone.

[0090] The above-mentioned components are particularly adapted to substantially minimize or eliminate any deformation of the remainder of the timepiece component when the element is driven into the component. In practice, they allow for a robust, reliable and permanent assembly of, for example, the escape wheel shaft, independently of any deformation of the arms or outer diameter, in particular of the teeth, of the gear wheel, which would be at risk of going out of round.

[0091] Furthermore, a receiving structure for such a component has the advantage that it is particularly compact and therefore easily integrated into the aesthetics of a given timepiece component.

[0092] The described timepiece parts are particularly suitable for axial mounting or driving in without or virtually without any deformation of the circumference caused by mounting on a shaft.

[0093] As used herein, "element extending in a first direction" preferably means that the element has a first dimension in the first direction that is at least greater than, or at least twice as large as, a second dimension in a second direction perpendicular to the first direction, where the first and second directions are perpendicular to the axes A1, 1A1.

[0094] Alternatively or additionally, as used herein, "an element extending in a first direction" means that the element mechanically connects two spaced apart elements that extend or substantially extend in a second direction perpendicular to the first direction. [Explanation of symbols]
