The front end of the balance shaft 66 is kept movable in rotation by the cage plate 51 via the bearing 67a, and its rear end kept movable in rotation by the balance bridge 65 via the bearing 67b. A double roller 70 is inserted in the part of the balance shaft 66 located on the front side with respect to the balance wheel 67. A notch 71 constituting a radial notch inward (in the shape of a crescent moon, see Figure 4) is formed in a part of the double roller 70 in the peripheral direction of the balance shaft 66.
    The balance wheel 67 is equipped with a hub 73 fixed to the balance shaft 66 by force fitting or the like, with a rim 74 surrounding the hub 73 on the outer side in the radial direction of the shaft balance 66, and a connecting portion 75 connecting the hub 73 to the rim 74. The hub 73 is provided with a chainring pin 76. The chainring pin 76 protrudes to the front side from the hub 73.
    The hairspring 68 is a flat hairspring which is a hairspring in a plan view taken in the axial direction of the balance shaft 66. The inner end of the hairspring 68 is connected to the balance shaft 66 by a ferrule 79, and its outer end is connected to a stud (not shown).
    As shown in Figure 3, the exhaust mobile 62 is rotatably supported between the cage plate 51 and an anchor / escape wheel bridge 81 arranged opposite on the rear side relative to the cage plate 51. The anchor / escape wheel bridge 81 is arranged between the cage plate 51 and the balance bridge 65.
    [0058] According to a plan view, part of the exhaust mobile 62 overlaps the balance-spring 61. More specifically, the exhaust mobile 62 is equipped with an axis 82, an exhaust pinion 83 formed on the axle 82, and an escape wheel 84 inserted in and fixed to the axle 82.
    The front end of the axis 82 is kept movable in rotation by the cage plate 51 by means of a bearing, and its rear end is kept movable in rotation by the anchor / wheel bridge exhaust 81 via a bearing.
    A plurality of teeth are provided on the outer peripheral surface of the escape wheel 84.
    The exhaust pinion 83 meshes with the aforementioned fixed wheel 42. Thus, the exhaust mobile 62 performs a satellite-type rotational movement while performing a rotational movement around the fixed wheel 42 through cage rotation 41.
    <Anchor>
    As shown in Figure 4, the anchor 63 connects the balance - hairspring 61 to the exhaust mobile 62. The anchor 63 is kept movable in rotation between the cage plate 51 and the anchor bridge / escape wheel 81, so that it can perform rotary reciprocating movements. More specifically, the anchor 63 is provided with an anchor pin 85, an anchor body 86 attached to the anchor pin 85, paddles 87 and 88 attached to the anchor body 86, and of a dart 89.
    The front end of the anchor pin 85 is kept movable in rotation by the cage plate 51 via a bearing 90a, and its rear end is kept movable in rotation by the bridge. anchor / escape wheel 81, via a bearing 90b. A through hole 81a through which the balance shaft 66 passes is formed in the part of the anchor / escape wheel bridge 81 overlapping the aforementioned balance shaft 66 in the axial direction. Figure 5 is a partial plan view, from the rear side, of the exhaust regulator 54. Figure 6 is a perspective view, from the rear side, of the anchor 63. Figure 7 is a side view. anchor cut 63.
    As shown in Figures 5 to 7, the anchor body 86 is equipped with an anchor base 93, an input / output horn connecting portion 94, a pair of input horns 95 and exit, and a rod 96. The anchor base 93, the input / output horn link portion 94, the input / output horns 95, and the rod 96 are integrally formed by electroforming or similar.
    The anchor base 93 is formed as a plate extending along the radial direction of the anchor axis 85. At the central portion in the direction in which the base extends. anchor 93, the anchor pin 85 is introduced in the axial direction by press fit or the like. As illustrated in Figures 3 and 4, in the axial direction of the anchor axis 85, the anchor base 93 is arranged at a position equivalent to that of the escape wheel portion 84 of the escape wheel set. 62, and is opposite the escape wheel portion 84. As shown in Figures 5 to 7, at both ends in the direction in which the anchor base 93 extends, there are formed mounting portions. pallet (an inlet mounting portion 100 and an outlet mounting portion 101), having an opening directed towards the exhaust mobile 62. In the following description, reference will be made to the axial direction of the axis anchor 85 simply as corresponding to the axial direction, and reference will also be made to the radial direction of anchor axis 85 (the direction orthogonal to the axial direction) simply as corresponding to the radial direction.
    The aforementioned pallets 87 and 88 are mounted respectively in the pallet mounting portions 100 and 101. The pallets 87 and 88 include the inlet pallet 87 mounted in the inlet mounting portion 100, and the pallet outlet 88 mounted in the outlet mounting portion 101. The vanes 87 and 88 are engaged and respectively released from the escape wheel 84 (more exactly from its external toothed part) of the escape mobile 62 by rotation of the anchor 63. More specifically, the inlet pallet 87 is engaged with and disengaged from the escape wheel 84 from this side in the rotational direction of the escape mobile 62 (see arrow C in FIG. 5) with respect to the figure. output pallet 88. The output pallet 88 is engaged in the teeth of the escape wheel 84 and disengaged from the latter in the direction of the depth of the exhaust mobile 62 relative to the input pallet 87 in the rotational direction C.
    The input / output horn link portion 94 extends from the end of the input mounting portion 100 of the anchor base 93 outwardly in the radial direction. In a plan view, the inlet / outlet horn connecting portion 94 gradually increases in width as it extends toward the distal end. As illustrated in Fig. 7, in a sectional view taken in the axial direction, the input / output horn connecting portion 94 projects rearwardly with respect to the anchor base 93. Thus, the portion inlet / outlet horn link 94 extends in the radial direction in a position offset rearwardly from the anchor base 93. In this case, as shown in Figure 4, the rear surface of the inlet / outlet horn linkage portion 94 is located behind the surface of the anchor / escape bridge 81. In other words, a portion of the inlet horn linkage portion 94 is located in the through hole 81a allowing passage of the anchor / escape bridge 81 mentioned above. The thickness of the inlet / outlet horn connecting portion 94 is equivalent to the thickness of the anchor base 93.
    As shown in Figures 5-7, the inlet and outlet horns 95 protrude radially outward from the input / output horn connecting portion 94. A pair of horns 95 d The inlet and outlet is arranged on the inlet / outlet horn connecting portion 94, the inlet horn and the outlet horn being disposed side by side. The distal end surface of each of the inlet and outlet horns 95 is an inwardly sloping surface in the width direction of the input / output horn connecting portion 94. And, the defined portion by the inlet and outlet horns 95 and the input / output horn linkage portion 94 forms a pallet box 105 open outwardly in the radial direction of the anchor axis 85. The anchor pin 85 plate 76 is removably housed in the pallet box 105 by rotation of the aforementioned balance spring 61. In the example illustrated, the inlet and outlet horns 95 are thinner than the input horn connecting part. / exit 94.
    The aforementioned dart 89 is mounted to the inlet horn connection part 94 from the front side. More specifically, the stinger 89 is equipped with a stinger main body 89a and a mounting protrusion 89b integrally formed with the proximal end of the stinger main body 89a. The mounting projection 89b is fixed to the aforementioned input / output horn connecting portion 94 from the front side by press-fitting or the like. In a plan view, the dart main body 89a located between the inlet and outlet horns 95 (inside the pallet box 105) extends outward in the radial direction. The width of the stinger main body 89a gradually decreases as one moves toward the distal end. As illustrated in Figure 5, the stinger 89 serves to prevent erroneous rotation of the anchor 63. This means that in the state in which the deck peg 76 is spaced from the pallet box 105, the stinger 89 may be. brought into sliding contact with the part of the outer peripheral surface of the double roller 70 other than the notch 71. On the other hand, when the pallet box 105 and the platform peg 76 are engaged with each other, the dart 89 is housed in the notch 71 of the double roller 70. In the example of FIG. 4, the surface of the dart 9 is located behind the surface of the anchor base 93.
    As shown in Figures 5 to 7, the rod 96 projects radially outwardly from the outlet mounting portion 101 of the anchor base 93. Further, in a sectional view taken on along the axial direction, the rod 96 protrudes rearwardly from the anchor base 93. Thus, the rod 96 extends in the radial direction in a position offset rearwardly from the base. anchor 93. As shown in Fig. 4, in this case, the rear surface of the rod 96 is located on the rear side of the surface of the anchor / escape bridge 81. In other words, part of the rod 96 overlaps the anchor / escape bridge 81 in the radial direction. The thickness of the rod 96 is equivalent to the thickness of the anchor base 93.
    As shown in Figures 4 and 5, in the plan view, on the parts of the aforementioned cage plate 51 located on both sides of the rod 96 (on both sides in the peripheral direction of the axis of anchor 85), there is a pair of limiting pins 114 and 115. The limiting pins 114 and 115 stand on the cage plate 51 towards the rear side. Through the rotation of the anchor 63, the rod 96 can be brought into contact with the rear ends of the limiting pins 114 and 115. Due to this architecture, the amplitude of the rotational movement (operational angle) of anchor 63 is restricted.
    In addition, as illustrated in Figure 4, each limiting pin 114, 115 has a narrower part 116 (constriction) in its central part according to their direction of extension (the part which is at the front of the part brought into contact with the rod 96 and which is located on the rear side of the part connected to the cage plate 51). Figure 4 shows only the narrower portion 116 of the limitation pin 114. The narrower portion 116 has a reduced diameter compared to the front end portion and the rear end portion of each limitation pin 114, 115. Each limiting pin 114, 115 allows for flexural deformation starting from the narrower portion 116.
    Here, as shown in Figures 5 to 7, in the anchor described above 63, the inlet pallet 87 and the outlet pallet 88 are respectively arranged on both sides relative to the axis of anchors 85 in the radial direction. Further, on the side opposite to the anchor axis 85 with respect to the vanes 87 and 88 (the outer side in the radial direction), the inlet and outlet horns 95, and the rod 96 are respectively arranged. , as shown in Figure 7, in a side view taken, from the radial direction, in the direction orthogonal to the direction in which the stinger 89 extends (the straight line P1 of Figure 5 (first radial direction)) and to the axial direction (the straight line Q of FIG. 5 (second direction)), the inlet and outlet horns 95, the inlet vane 87, the anchor axis 85, the outlet vane 88, and the rod 96 are successively arranged in this order along the direction of extension P1 of the stinger 89. In particular, according to the present embodiment, the direction of extension P1 of the stinger 89 and the direction of extension P2 of the rod 96 (other radial direction) are arranged as being coincident along the same straight line passing through the 'anchor pin 85.
    Further, as described above, in anchor 63 of this embodiment, the input / output horn link portion 94 (and the input and output horns 95) and the rod 96 are offset rearwardly with respect to the anchor base 93. In other words, the rear surface of the anchor base 93 is recessed on the front side with respect to the rear surfaces of the horn linkage portion. inlet / outlet 94 (and the inlet and outlet horns 95) and rod 96. As shown in Figure 4, in this case, the part defined by the anchor base 93, the connecting part inlet / outlet horn 94, and the rod 96 constitute a housing part of the bearing 120 receiving the aforementioned bearing 90b.
    While according to the present embodiment described above the housing portion of the bearing 120 is formed to cover the entire anchor base 93, a range of possibilities for forming the housing portion of the bearing 120 allows a change of design. For example, this may be formed only at a portion of the anchor base 93. As long as at least a portion thereof is formed on the anchor base 93, the housing portion of the bearing 120 can be formed such that it is disposed, by means of the offset in height, astride above or below the input / output horn connecting portion 94 or the rod 96.
    The aforementioned vortex 13 operates as follows.
    As shown in Figure 1, when the energy of the barrel of the movement 21 is transmitted to the fifth mobile 43 by the front gear 12, the fifth mobile 43 is rotated. The energy of the fifth mobile 43 is transmitted to the cage pinion 52c, through which the entire cage 41 rotates around the cage axis 52b, 53b of the cage 52, 53. Due to the rotation of the cage 41, the balance spring 61 arranged coaxially with the cage axis 52b, 53b rotates around the cage axis 52b, 53b. Consequently, it is possible to stabilize the influence of the gravitational force acting on the balance spring 61, by suppressing any change in the oscillation cycle of the balance spring 61 depending on the direction of the gravitational force. Cage 41 is set to rotate every 60 seconds.
    In addition, as illustrated in Figures 1, 3, and 4, due to the rotation of the cage 41, the exhaust mobile 62 performs a rotary movement while performing a revolution around the fixed wheel 42. In Furthermore, as shown in Figures 5 and 8, when the anchor 63 rotates around the anchor axis 85 due to the free oscillation of the balance spring 61 around the balance shaft 66, the pallet d 'inlet 87 and the outlet pallet 88 are engaged alternately and released relative to the escape wheel 84 of the escape wheel 62. When a pallet among the inlet pallet 87 and the outlet pallet 88 is engaged with the escape wheel part 84, the rotation of the escape wheel 62 is temporarily stopped. Further, when the inlet vane 87 and the outlet vane 88 are released from the escape wheel portion 84, the exhaust mobile 62 rotates. These operations are repeated successively, and thanks to them, the timepiece 1 measures the passage of time.
    In this way, in the present embodiment, according to a side view taken from the direction Q orthogonal to the direction P in which the stinger 89 extends and to the axial direction of the anchor 63, the horns 95 entry and exit, the entry pallet 87, the exit pallet 88, and the rod 96 are arranged in this order along the direction P of extension of the stinger 89.
    In this architecture, compared to the conventional architecture according to which the rod 96 is connected in a secant direction with respect to the direction of extension of the anchor base 93, and in which the inlet horns 95 and outlet are connected to the distal end part of this rod 96, it is possible to achieve a reduction in size of the anchor 63 in the direction secant to that along which the anchor base 93 extends according to a plan view taken from the axial direction.
    Furthermore, in the present embodiment, the bearing 90b is received in the housing part of the bearing 120 formed on the anchor base 93, so that it is possible to reduce the axial distance between the bearing 90a and the cage plate 51.
    Further, in the present embodiment, the rod 96 is formed on the part of the pallet base 93 on the side opposite to the inlet and outlet horns 95, so that when the anchor 63 is mounted in the regulator exhaust 54, it is possible to arrange the rod 96 in a position remote from the balance shaft 66. Therefore, it is easier to perform maintenance work on the rod 96.
    Further, in the present embodiment, the anchor base 93, the input / output horn connecting portion 94, the input and output horns 95, and the rod 96 are formed of in one piece as the body of the anchor 86, so that, compared to the case where these parts are formed separately, it is possible to make the anchor 63 with better precision.
    In the exhaust - regulator 54 of this embodiment, the above-mentioned anchor 63 is provided, so that it is possible to achieve a reduction in size and thickness for the exhaust - regulator 54. For example, the bearing 90b is received in the housing part of the bearing 120, so that it is possible to reduce the axial distance between the anchor / escape wheel bridge 81 and the anchor 63. For example, Consequently, it is possible to bring the balance - spring 61 and the anchor 63 closer to each other in the axial direction, making it possible to obtain a reduction in thickness for the escapement - regulator 54.
    In the exhaust - regulator 54 of the present embodiment, each limiting pin 114, 115 has a narrower portion 116, so that each limiting pin 114, 115 can be easily bent from the narrower portion 116. Therefore, it is easy to adjust the distance between the limiting pins 114 and 115, allowing to easily adjust the amplitude of rotation of the anchor 63. Therefore, it is possible to realize an improvement in terms of maintenance.
    In the regulator exhaust 54 of this embodiment, the plate pin 76 is disposed on the balance wheel 67, whereby, compared to the case where the plate pin 76 is arranged on a wide rim of the double roller 70, it is possible to reduce the thickness of the balance - spring 61 and, by extension, to reduce the thickness of the escapement - regulator 54.
    In the present embodiment, the anchor 63 and the escapement - regulator 54 as described above are adopted in a structure such as the tourbillon 13, which involves a large number of components and which is liable to 'be large. Thanks to them, it is possible to achieve a marked reduction in terms of size and thickness as mentioned above.
    In addition, in the movement 10 and the timepiece 1 according to the present embodiment, the anchor described above 63 is provided, so that it is possible to obtain a movement 10 and a timepiece 1 which are reduced in size and thickness.
    (Modifications)
    In what follows, modifications and variants of the embodiment described above will be described. In the embodiment described above, the direction P1 along which the stinger 89 extends and the direction P2 along which the rod 96 extends are combined to form a single straight line passing through the anchor pin 85. This should not, however, be interpreted restrictively. Other architectures will also work as long as the inlet and outlet horns 95, the paddles 87 and 88, and the rod 96 are arranged successively one after the other along the direction P1 of extension of the stinger 89 according to a side view taken from the direction Q orthogonal to the direction P1 of extension of the stinger 89 and to the axial direction of the anchor 63.
    For example, as in the case of an anchor 150 shown in Figure 9, the direction P1 of extension of the stinger 89 and the direction P2 of extension of the rod 96 can be mutually secant. Further, the direction P1 of extension of the stinger 89 may not coincide with the direction of extension of the anchor base 93 and the radial direction. In other words, the direction P1 of extension of the stinger 89 can intersect with the direction of extension of the anchor base 93 and with the radial direction.
    Further, as in the case of an anchor 151 shown in Figure 10, the rod 96 may be formed at the end of the inlet mounting portion 100 of the anchor base 93. On the other hand, in the anchor 151, an input / output horn link portion 155 extends from the central portion in the direction in which the anchor base 93 extends (its portion between the portions of the anchor. pallet mounting 100 and 101) in a direction intersecting with the extending direction of the anchor base 93. The inlet and outlet horns 95, and the aforementioned stinger 89 are arranged at the level of the anchor. distal end of I / O horn connecting portion 155.
    Also in the architecture shown in Figure 10, the inlet and outlet horns 95, the paddles 87 and 88, and the rod 96 are arranged in this order along the direction P1 of extension of the stinger 89 according to a side view in the direction Q orthogonal to the direction P1 of extension of the stinger 89 and to the axial direction of the anchor 63. Therefore, compared to the architecture according to which the inlet and outlet horns 95 are protruding out of the rod 96, it is possible to achieve a reduction in size of the anchor 63 in the direction intersecting the direction along which the anchor base 93 extends.
    Furthermore, in the embodiment and the modification described above, the rod 96 is disposed at the level of the end of the anchor base 93, on the side opposite to the inlet and outlet horns 95 relative to anchor axis 85. This should, however, not be interpreted restrictively. Any other architecture will work as long as the rod 96 is arranged on the side of the anchor pin 85 on the proximal end portion of the stinger 89 (the input / output horn connecting portion 94 or the proximal end portion of the inlet / outlet horn connecting portion). For example, the rod 96 may be arranged on the part of the anchor base 93 located between the pallet mounting portions 100 and 101.
    The technical field of application of the present invention is not limited to that of the embodiment described above, but allows various modifications within the scope of the claims without departing from the scope or the spirit of the present invention.
    For example, in the embodiment described above, an escapement - regulator equipped with the anchor according to the present invention is mounted in the movement 10 equipped with the tourbillon 13, which should not however be interpreted in such a way. limiting.
    In addition, in movement 10, the arrangement of the wheels, etc. can be modified as appropriate from case to case.
    While, in the embodiment described above, the housing portion of the bearing 120 is recessed on the front side, such a configuration should not be interpreted restrictively; this could also be recessed towards the rear side.
    Furthermore, while in the embodiment described above the housing part of the bearing 120 receives a part of the bearing 90b and the anchor / escape bridge 81, any other architecture will be suitable as long. that at least part of the bearing 90b can be accommodated there.
    Apart from this, the components of the embodiment described above can be replaced by other well known components if necessary without departing from the scope or the spirit of the present invention; furthermore, the modifications described above can be combined with each other as appropriate from case to case.
