Description

Description Title of the invention: COMPACT MODULE COMPRISING A OSCILLATOR-EXHAUST SYSTEM FOR CLOCK MOVEMENT Technical field of the invention

[0001] = The present invention relates to the field of mechanical watchmaking and concerns, More specifically, a watch module with an oscillator-escapement system designed for greater compactness. State of the art

[0002] = We often seek to reduce the thickness of components in a watch movement, for example, for aesthetic reasons. There is also a constant desire to increase the efficiency of watch movements and reduction of wear on constituent components mechanical movement.

[0003] … Mechanical watch movements include a driving element providing motive power, a transmission component, a maintenance component - metering and a regulatory body.

[0004] — In general, the component supplying the motive power is a barrel which acts as an ac- Energy accumulator and energy reserve: it is either armed by the user or by a an oscillating mass that gradually releases the energy it has stored. The organ The transmission system is most often a train of gears that transmits energy up to the exhaust sprocket. The regulating organ or regulating organ is an organ The oscillator is generally in the form of a balance wheel and hairspring assembly. The organ The maintenance and counting system is an escapement that maintains and counts oscillations. of the balance wheel. It receives energy from the mainspring barrel via the pinion escapes and releases a quantity of this energy to restore it to the regulatory body.

[0005] = In the oscillator-escapement system, the oscillating element and the element escapements each present a mobile escapement axis an escapement and an oscillator axis, which axes are parallel to each other. The inter- axis, namely the distance separating the escapement axis from the oscillator axis, is variable depending on the type and geometry of the watch movement and oscillator.

[0006] There are also oscillator-escapement systems with a caged tourbillon. In this case, the cage adds a component to the inertia of the oscillating system. escapement, and it contributes significantly to the bulk of the watch movement in different dimensions. Summary of the invention One aim of the invention is to provide a watch module with an oscillator-escapement system that is compact, in particular with a low thickness, for a watch movement. Another aim of the invention is to provide a watch module with an oscillator-escapement system having low inertia and improved efficiency. One aim of the present invention is to propose a watch module with an oscillator-escapement system free from the limitations of known watch modules. According to the invention, these goals are achieved in particular by means of a watch module comprising an escapement, an oscillator and a frame, said escapement comprising an escape wheel mounted to rotate about an escapement axis via a single escapement pivot link between the escape wheel and the frame, said oscillator comprising a balance-hairspring assembly mounted to rotate about an oscillator axis via a single oscillator pivot link between said balance-hairspring assembly and the frame, in which said escape axis and said oscillator axis are coaxial, and in which said escape pivot link and said oscillator pivot link have at least one common plane orthogonal to the escape axis and the oscillator axis. This solution has the advantage, in particular, compared to the previous art, of offering a much more compact oscillator-escapement system. On the one hand, the oscillator-escapement system is of the single-axis type, since the escapement axis and the oscillator axis are coaxial. On the other hand, the oscillator-escapement system has a reduced number of links. Thus, the escapement axis and the oscillator axis coincide. Furthermore, the escape wheel is mounted to rotate around the escapement axis by means of a single escapement pivot linkage. And since the balance wheel and hairspring assembly is mounted to rotate around the oscillator axis via a single oscillator pivot linkage, there are fewer parts, which helps to reduce efficiency loss. Furthermore, compactness is improved by the fact that the escapement pivot joint and the oscillator pivot joint share at least one common plane orthogonal to the escapement axis and the oscillator axis. In other words, there is overlap between the vertical extent of the escapement pivot joint and the vertical extent of the oscillator pivot joint. For example, the escapement pivot joint and the oscillator pivot joint may be placed around or within each other. Thus, the escapement pivot joint may surround the oscillator pivot joint, or the oscillator pivot joint may surround the escapement pivot joint. When the escapement pivot joint surrounds the oscillator pivot joint (or vice versa), this may be over the entire height of either the oscillator pivot joint or the escapement pivot joint. well only on a portion of the height of the oscillator pivot joint or the escapement pivot joint. According to one possible implementation, said escapement pivot link and said oscillator pivot link are concentric. According to one possible implementation, the oscillator pivot joint and the escapement pivot joint belong to a double bearing. In this case, each bearing of the double bearing is concentric with the other bearing of the double bearing and is also located within or around the other bearing of the double bearing. These are not bearings placed one on top of the other, but rather two bearings placed one inside the other. This solution does not preclude the double bearing from belonging to a bearing with more than two bearings, in particular three, four, or more bearings. According to one possible implementation, the double bearing is a ball bearing with at least three concentric cages. Each pair of adjacent cages retains a row of balls, allowing rotation of each cage in that pair relative to the other cage in that pair. Thus, each pair of adjacent cages forms a bearing and is located either around or within another cage, over all or part of the height of the ball bearing cages. Therefore, a ball bearing with three concentric cages, or more than three concentric cages, such as four or five cages, can be used. A ball bearing with ceramic balls can be used, thus providing a lubrication-free and low-friction bearing. Other implementations of this double bearing are possible, for example a drilled bearing with dry friction, or a bearing with ruby ​​cages where the friction between each cage is of the dry nano-lubricated type. The present invention also relates to a watch movement comprising a watch module as described and set forth in this patent application. Such a watch movement further comprises, in particular, a bridge or a mainplate. The present invention also relates to a watch comprising a watch case and a strap, said watch case comprising a watch movement as described and disclosed in this patent application. Such a watch may be a chronograph watch, or any other type of watch. Also, said watch movement may belong to any timepiece, in particular a clock. Also, said watch movement may belong to a writing instrument or any other device capable of containing a watch movement.

Description of the implementation methods We now refer to Figures 1 to 4, which represent a first variant of a first embodiment of a watch module 100 with an oscillator-escapement system according to the invention. In the kinematic diagram of [Fig. 1], we find the escapement mechanism 20, which includes the escape wheel 21, the anchor 22, the double plate 23, and the limiting stops 24. The escapement mechanism 20 is also connected to the oscillator 30 by the anchor 22. Within the escapement mechanism 20, the escape wheel 21 comprises the wheel The escapement 211, superimposed with the escape pinion 212, is pivotally mounted around the escapement pivot joint P2, around point B. In the oscillating organ 30, the balance wheel-hairspring assembly 31, comprising the balance wheel 311 connected to the hairspring 312, is pivotally mounted around the oscillator pivot joint P3, around point B. The pallet fork 22 also has a pivot joint at its end, and its first end, fitted with pallets 22c, cooperates with the escape wheel 211, while the second end of the pallet fork 22b cooperates with the pin 23a of the double plate 23, which is integral with the balance shaft 32 of the balance wheel 311, via its fork 22b. The dart 22a performs its safety function by its shape in conjunction with the small plate of the double plate 23. According to the invention, point A equals point B (A=B, point A and point B are superimposed, therefore coincident), which means in particular that the escapement axis A2 and the oscillator axis A3 are positioned in the same location and are superimposed, therefore identical. The frame 40 serves as a support for fixing the fixed, non-moving parts of the clock module 100, in this case the support for the pivot shaft of the anchor 22, and the part surrounding the pivot shaft of the oscillator pivot P3 (this is an intermediate cage 53 of the double ball bearing visible in [Fig. 4]). Figures 2 to 4 show the elements just described in relation to [Fig. 1], in a physical arrangement of the clock module 100, now specified. In the representation in [Fig. 2], the base of the clock module 100 is formed by the frame 40. On the left of [Fig. 2] or 4, the pivot shaft of the anchor 22, mounted on the frame 40, is visible. On the right of [Fig. 2] or 4, the escapement 20 and the oscillator 30 are stacked one on top of the other, with the escapement 20 positioned between the frame 40 and the oscillator 30. A central shaft 32 forms the central element of the oscillator pivot P3. This central shaft 32 is centered on and parallel to the oscillator axis A3 and the escapement axis A2. In its end portion opposite the frame 40 (at the top in [Fig.4]), the central shaft 32 is the support for the balance wheel 311 (the center of the balance wheel is pivotally mounted on the central shaft 32). Below the balance wheel 311, the ferrule of the spiral spring 312 is pressed onto the central shaft 32. Below the spiral spring 312, the double plate 23 is pressed onto the central shaft 32. Below the double plate 23, the other end portion of the central shaft 32 is pressed into the inner cage 51 of the ball bearing 50. The ball bearing 50 comprises three cages: an inner cage 51, an outer cage 52, and an intermediate cage 53. The intermediate cage 53 is fixedly mounted on the frame 40, and the outer cage 52 carries the escapement wheel 21, with the pinion 212 surmounted by the escape wheel 211, whose teeth cooperate with the pallets 22c of the anchor 22. The anchor 22 is of the counterweight rod type, the fork 22b cooperating with the pin 23a of the double plate 23. Limiting stops 24 serve to limit the travel of the anchor 22 on either side of the anchor rod (see [Fig. 2]). Figure 4 shows that the vertical extent H3 of the oscillator pivot joint P3 shares a portion of the vertical extent H2 of the escapement pivot joint P2. Within this shared vertical extent, a plane P1, common to both the oscillator pivot joint P3 and the escapement pivot joint P2, is shown in Figure 2. This common plane P1 is orthogonal to the escapement axis A2 and the oscillator axis A3. In reality, there are numerous possible parallel planes P1. These planes P1 intersect the ball bearing 50. Each of these planes P1 is parallel to the mean plane of this ball bearing 50 and passes through the ball bearing 50. All of these planes P1 lie within the entire vertical extent of this ball bearing 50. We now refer to Figures 5 to 8, which represent a second variant of a first embodiment of a clock module 100 with an oscillator-escapement system according to the invention. Unless otherwise stated, the information described previously in relation to the first variant remains valid. In particular, as can be seen in [Fig. 5], the kinematic diagram is very similar to that of the first variant, shown in [Fig. 1]. One difference lies in the fact that in the escapement pivot P2 connection, the escapement wheel 21 is fixed to the central part of the escapement pivot P2 through which the escapement shaft A2 passes.Another difference lies in the fact that it is not the part surrounding the pivot shaft of the oscillator pivot link P3 that is fixed to the frame 40 but the part surrounding the pivot shaft of the escapement pivot link P2 (this is an external cage 52 of the double ball bearing visible in figures 7 and 8). Figures 6 to 8 show the elements just described in relation to [Fig. 5], in a physical arrangement of the clock module 100, now specified. In the representation of [Fig. 6], the frame 40 does not form the base of the clock module 100, but rather the escapement wheel 21, and in particular the pinion. The escapement 212 forms the base of the watch module 100. The frame 40 is positioned between the oscillating element 30 and the escapement wheel 21. The frame 40 is a plate with an opening housing the double ball bearing 50. The internal cage 51 is movable and integral with the lower end portion of the central shaft 32. Above the double ball bearing 50, this central shaft 32 is integral with the ferrule retaining one end of the balance spring 312 and is surrounded by this ferrule. Above the spiral 312, this central shaft 32 is fixed to the double plate 23 and is surrounded by this double plate 23. Above the double plate 23, this central shaft 32 is fixed to the balance wheel 311 and is surrounded by this balance wheel 311. The intermediate cage 53 is movable relative to the outer cage 52 and relative to the inner cage 51.The intermediate cage 53 is integral with the escapement mechanism 21 (escapement wheel 211 and escapement pinion 212) located under the frame 40. The outer cage 52 is integral with the frame 40. In this case, the anchor 22 is stepped and passes through an opening in the frame 40. This means that the frame 40 has an opening 41 through which the anchor 22 passes, such that the fork 22b of the anchor is located on one side of the frame 40 and the pallets 22c are located on the other side. To allow the anchor 22 to pivot relative to the frame 40, another pivot joint is formed, here materialized (see Figures 6 to 8) by a ball bearing 42. Thus, as seen in Figures 7 and 8, the pallets 22c are located below the frame 40 and cooperate with the teeth of the escape wheel 211. As seen in Figures 6 and 8, the fork 22b and the dart 22a are located above the frame 40, between the balance spring 312 and the large platform of the double platform 23, and the fork 22b cooperates with the peg 23a of the double platform 23. The limiting stops 24 of the anchor 22 are visible in figures 7 and 8. As can be seen in figures 5 to 8, the double plate 23 of the oscillating organ 30 is coaxial with said oscillating axis A3 and is intercalated between the balance wheel 311 and the spiral 312. Also, the vertical extent H3 of the oscillator pivot joint P3 corresponds to the length of the central shaft 32, and shares a portion of the vertical extent H2 of the escapement pivot joint P2 corresponding to the height of the intermediate cage 5: within this shared vertical extent, a plane P1 common to the oscillator pivot joint P3 and the escapement pivot joint P2 is shown in [Fig. 8]. This common plane P1 is orthogonal to the escapement axis A2 and the oscillator axis A3. In reality, there are numerous possible planes P1, all parallel to each other. These planes P1 are contained within the height of the inner cage 51 of the ball bearing 50 and are parallel to the mean plane of this ball bearing 50. We now refer to figures 9 to 12 representing a third variant of a first embodiment of a watch module 100 with an oscillator-escapement system according to the invention. Unless otherwise stated, the information described previously in relation to the second variant of the first embodiment remains valid. In particular, as can be seen in [Fig. 9], the kinematic diagram is very close to that of the second variant of the first embodiment, shown in [Fig. 5]. One difference lies in the fact that there is an additional pivot joint (point B in [Fig. 9]), between the escapement pivot joint P2 (point C in [Fig. 9]) and the oscillator pivot joint P3 (point A in [Fig. 9]), which coincide with each other (A=B=C). Specifically, as can be seen in figures 10 to 12, the ball bearing 50 comprises four cages: the inner cage 51, the outer cage 52, the intermediate cage 53 and an additional intermediate cage 54. The outer cage 52 is integral with the frame 40.The additional intermediate cage 54 is positioned between the intermediate cage 53, which is integral with the escapement wheel 21, and the inner cage 51, which is integral with the central shaft 23 on which the balance wheel and balance spring assembly 31 is mounted. This additional intermediate cage 54 is fixed (mounted on the frame 40), while the inner cage 51 and the intermediate cage 53 are free to rotate relative to this additional intermediate cage 54, around the escapement axis A2, which is superimposed on the oscillator axis A3. In this way, direct contact is avoided between the mobile cage integral with the balance wheel and balance spring assembly 31 (of the moving part of the oscillator 30) and the mobile cage integral with the escapement wheel 21 (of the moving part of the escapement 20). This precaution, in particular, prevents the clock module 100 from being affected by the inertia of the balance wheel 311's movement. In this case also, as in the second variant of the first embodiment, the anchor 22 is stepped and passes through an opening 41 in the frame 40, with a ball bearing 42 to materialize the pivot connection of the anchor 22. The first embodiment of the watch module described above is characterized by a balance wheel and hairspring assembly which incorporates the traditional components of a balance wheel and hairspring assembly, arranged compactly in combination with the escapement. We now refer to figures 13 to 16 representing an implementation of a second embodiment of a 100 clock module with a compact oscillator-escapement system according to the invention. In the kinematic diagram of [Fig. 13], we find the escapement 20 connected to the oscillating element 30 by the anchor 22. In the escapement 20, the escape wheel 21, comprising the escape wheel 211 superimposed with the escape pinion 212, is mounted to pivot around the escapement pivot joint P2, around point B. In the oscillating element 30, the balance wheel-hairspring assembly 31, comprising the balance wheel 311 connected to the balance spring 312, is mounted pivoting around the oscillator pivot joint P3, around point B. Point D corresponds to the center of the balance wheel 311. The anchor 22 also has a pivot joint at the level of its rod, and cooperates by its first end fitted with pallets 22c with the escape wheel 211, while the second end of the anchor 22 cooperates by its fork 22b with the pin 23a of the double plate 23 integral with the shaft 32 of the balance wheel 311. According to the invention, point A equals point B (A=B, point A and point B are superimposed, therefore coincident), which means in particular that the escapement axis A2 and the oscillator axis A3 are positioned in the same location, are superimposed and are identical.In the case of this second embodiment, point A equals point D (A=D, point A and point D are superimposed, therefore coincident): the balance wheel 311 forms the part surrounding the pivoting shaft of the oscillator pivot joint P3. The frame 40 serves as a support for fixing the fixed, non-moving parts of the watch module 100, in this case the shaft of the pivot joint of the anchor 22, and the part surrounding the pivoting shaft of the oscillator pivot joint P3 (this is an intermediate cage 53 of the double ball bearing visible in figures 14 and 16). Figures 14 to 16 show the elements just described in relation to [Fig. 13], in a physical arrangement of the clock module 100, now specified. In the representation of [Figs. 14] to 16, the base of the clock module 100 is formed by the balance wheel 311. On the left of [Fig. 16], the pivot shaft of the anchor 22, mounted on the frame 40, is visible via a ball bearing 42 located in an opening 41. In the center of the cross-section of [Fig. 16], the escapement 20 and the oscillating element 30 are stacked one on top of the other, with the escapement 20 above the frame 40 and the oscillating element 30. The frame 40 and the oscillating element 30 are nested within each other as explained below. The central element of the escapement pivot linkage P2 comprises the hub of the escape wheel 21, which supports the escape pinion 212 and the escape wheel 211. The escape pinion 212 corresponds to the upper element of the stack formed by the escapement mechanism 20 and the oscillating mechanism 30, and to the upper element of the clock module 100, at the top of [Fig. 16]. The hub of the escape wheel 21 is housed in the opening of the inner cage 51 of the ball bearing 50, so that the escape wheel 21 pivots with this inner cage 51. The intermediate cage 53 is fixed and belongs to the frame 40 of the clock module 100. The central element of the oscillator pivot link P3 comprises the double plate 23, located in the center of the case back of the clock module 100, surmounted by the balance spring 312. The balance spring 312 is thus situated between the double plate 23 and the bearing 50, beneath the inner cage 51 and the intermediate cage 53. The large plate of the double plate 23 is extended radially by two arms to the balance wheel 311, whose rim 31, or peripheral ring, is consisting of the outer cage 52 of the bearing 50. This bearing 50 comprises three cages, namely the aforementioned movable inner cage 51, the aforementioned fixed intermediate cage 53, and the movable outer cage 52. Therefore, there is no central shaft 32 as in the first embodiment. The intermediate cage 53 is fixedly mounted on the frame 40 and has an opening 41 retaining the anchor ball bearing 42, as in the second and third variants of the first embodiment. Above the ball bearing 50 (see Figures 14 and 16), the two arms of the anchor 22 carry the pallets 22c, which cooperate with the teeth of the escape wheel 211. The travel of the bearings is limited by two limiting stops 24 (see Figures 14 and 16). Below the ball bearing 50 (see Figures 15 and 16), the fork 22b cooperates with the platter pin 23a of the double platter 23. We see that the height H3 of the oscillator pivot joint P3 corresponds to the height of the balance wheel's rim 31, namely the height of the outer cage 52 of the bearing 50. The height H2 of the escapement pivot joint P2 corresponds to the height of the inner cage 51 of the bearing 50. Figure 16 shows that the height H3 of the oscillator pivot joint P3 shares a portion of the height H2 of the escapement pivot joint P2: within this shared height, a plane P1 common to both the oscillator pivot joint P3 and the escapement pivot joint P2 is shown in Figure 16. This common plane P1 is orthogonal to the escapement axis A2 and the oscillator axis A3. In reality, there are numerous possible parallel planes P1. These planes P1 are intersecting with the ball bearing 50 and parallel to the mean plane of this ball bearing 50. In this case also, as in the second variant and the third variant of the first embodiment, the anchor 22 is stepped and passes through an opening 41 of the frame 40, with a ball bearing 42 to materialize the pivot connection of the anchor 22. This second embodiment of the 100 watch module results in an extra-flat arrangement. The second embodiment of the watch module described above is characterized in particular by the fact that one of the cages of the ball bearing forms the rim 31 of the balance wheel of the balance-spring assembly 31. In the example described and illustrated in figures 13 to 16, it is the outer cage 52, of the set of three cages 51, 52, 53 of the double ball bearing 50, which forms the rim 31 of the balance wheel of the balance-spring assembly 31. This arrangement further improves the compactness of the watch module 100 thus obtained. In the embodiments presented here, the escapement 20 is a modified and compacted Swiss lever escapement, wherein said lever 22 is a inverted baguette anchor. According to one possible implementation, more generally, said escapement organ 20 is a free escapement, comprising an escape wheel 211, an anchor 22, a double plate 23 and limiting stops 24 for the travel of the anchor 22. In the embodiments presented here, the double bearing 50 for compacting the escapement 20 and oscillator 30 of the clock module 100 is a ball bearing 50 having at least three concentric cages (three cages 51, 52, 53 in the first and second variants of the first embodiment and in the second embodiment or four cages) concentric 51, 52, 53 and 54 in the third variant of the first embodiment), each pair of adjacent cages retaining a row of balls allowing the rotation of each cage of said pair relative to the other cage of said pair, and one cage out of two, namely one cage of each pair of cages, is fixed on the frame 40. In particular, among said at least three concentric cages (51, 52, 53), a first pair of adjacent cages and the corresponding row of balls forms said escape pivot link (P2) around the escape axis A2. Also, among the said at least three concentric cages (51, 52, 53), a second pair of neighboring cages and the corresponding row of balls form said pivot joint of oscillator (P3) around the oscillator axis A3. In the embodiments presented here, the escapement pinion 212 traditionally forms the entry piece of the watch module 100. In the case of the second variant and the third variant of the first embodiment and in the case of the second embodiment, the escapement pinion 212 is arranged outside the watch module 100, namely as a piece projecting on one of the faces of the stack of parts forming the watch module 100. It is understood that the present invention provides a solution in which said escapement organ and said oscillating organ are strongly mechanically linked to each other and very close geometrically to each other, or even nested one inside the other, which not only reduces the bulk, but also minimizes the number of links, friction and therefore energy losses. Test results for an oscillator-escapement system according to the invention have shown that this solution provides a gain of around 3% for the power reserve, which corresponds to a gain in efficiency of 3%. Thanks to the arrangement described in the present invention, a watch module with an economical and easy-to-manufacture oscillator-escapement system is proposed. Such a watch module can be integrated as a module into a watch movement comprising at least one bridge and a mainplate, and other elements such as, but not limited to, the mainspring (in particular a barrel) and the transmission element (the train). of gears), and possibly the winding and / or time-setting mechanism.
