    Description
    Background of the invention
    FIELD OF THE INVENTION [0001] The present invention relates to a timepiece such as a portable timepiece comprising a telescope that can be actuated in rotation.
    Description of the Related Art [0002] A timepiece in which a bezel actuated in rotation by a user is mounted on a middle part of a case is known from the prior art relating to it (for example, see JP-A -2003-43 162 [Patent Document 1]).
    In the timepiece disclosed in the patent document 1, the bezel is mounted on the middle part so as to be free to rotate, locking a flange portion to be locked continuously provided around a peripheral surface internal portion of the bezel on a portion in a locking collar provided continuously around an outer peripheral surface of a rising portion constituting the middle part. Here, the bezel and the caseband are both made of metal, and these flange portions are locked by pressing the bezel on the case using a strong force of a pressing machine and so on to allow thus to the flanged portion to be locked to mount over a lower portion of the locking flange portion. In this way, the bezel is prevented from detaching from the housing.
    In addition, in the timepiece disclosed in the patent document 1, a lining material made of an elastic member is interposed between the outer peripheral surface of the rising portion and the inner peripheral surface of the bezel, as well as on the upper side of the locking flange portion. The bezel is held in a stationary state by the packing material so as not to be moved. Since such a lining material is used, the rotation of the bezel is possible in the case where the user exerts a torque in rotation exceeding a certain level by means of a rotating operation of the bezel.
    When sand particles enter between the middle and the bezel or accumulates dust, the operation of rotating the bezel can be difficult (not smooth). In addition, a deterioration of the lining material takes place over time, the operation of rotating the bezel can become difficult, as the deteriorated lining material can stick to the caseband and the bezel if the actuation in rotation has not been done for a long time.
    In the maintenance to correct the situation above, after the bezel has been removed from the caseband once, the middle and the bezel are cleaned, or the packing material is replaced, after which the bezel is back on the middle. To remove the bezel from the case during maintenance, a disassembly tool is inserted between the bezel and the caseband, and the bezel is detached using this tool. The mounting of the cleaned bezel on the middle part is achieved by pressing the bezel on the middle part using a strong force.
    The deformation of the constituent portion of the flange portion of the middle part made of metal and the flange portion to be locked constituting the bezel made of metal is not easy. As a result, when the portion in the form of a locking flange of the middle and the flanged portion to be locked of the bezel interfere with each other during assembly and removal of the bezel as previously described, these flange portions are eroded. Also, there is a problem that as the number of withdrawals and mountings of the telescope increases, the interference of securement between the locking flange portion and the flanged portion to be locked decreases and the bezel decreases. is easily removed from the middle part.
    In timepieces of the related art, there is another problem which is that the dedicated lining material is necessary not only for securing between the locking flange portion and the flange portion to lock to maintain the state in which the bezel is mounted on the middle part, but also to prevent the jiggle of the bezel and to calibrate the torque of rotation. SUMMARY OF THE INVENTION [0009] An object of the present invention is to provide a timepiece able to maintain reliability in maintaining the state where the bezel is mounted on the middle part, and able to prevent jiggle the bezel and calibrate the rotating torque without the use of the dedicated lining material even when the bezel is removed for maintenance.
    In order to solve the above problems, there is provided a timepiece comprising a housing having a middle part having an annular convex portion and a securing projection formed at an outer periphery of the portion. convex ring to extend in a circumferential direction, a ring-shaped bezel having an inner peripheral concave portion surrounding the outer periphery of the annular convex portion and rotatably operable while covering the outer periphery of the annular convex portion; annular convex portion, and a ring-shaped connecting member having an outer peripheral portion arranged in the inner circumferential concave portion, an inner peripheral portion with an annular groove allowing elastic deformation towards and away from the peripheral portion external, formed between the periph internal carrier and the outer peripheral portion, which is connected to the outer peripheral portion, and a securing portion formed in the inner peripheral portion, capable of securing to and freeing from the securing projection by deforming resilient of the inner peripheral portion, which maintains a securing state between the securing projection and the securing portion via an elastic force of the inner peripheral portion.
    In the present invention, the middle part is preferably made of metal, and the bezel can be made of metal or a synthetic resin. Preferably, the assembly member is a one-piece molded part of elastic material, for example synthetic resin having elasticity, in the present invention. The assembly member may be attached to the inner peripheral concave portion of the bezel by using an adhesive at its outer peripheral portion. In addition, the assembly member can be held by the telescope so as to move relatively in the direction of rotation of the telescope or can be positioned in the telescope so as to rotate integrally with the telescope in a state wherein the outer peripheral portion and so on touches the inner peripheral concave portion of the bezel as described in the embodiment of the present invention.
    To mount the bezel on the middle part in the timepiece according to the present invention, the bezel is assembled to the housing so that the assembly member surrounds the outer periphery of the annular convex portion constituting the middle part in the state where the assembly member is previously held in the inner peripheral concave portion of the bezel. As a result, the fastening portion of the fastener rises over the securing projection of the annular convex portion and immediately thereafter the fastening portion engages with the fastening protrusion in the fastening projection of the annular convex portion. a state where it is captured from a root side of the annular convex portion, which keeps the bezel assembled to the middle part. To remove the bezel from the caseband during a maintenance, it is better to add an external force on the bezel to remove the telescope forcibly. Therefore, the securing portion captured by the securing projection of the annular convex portion can mount over the securing projection to thereby remove the bezel from the caseband.
    When the securing portion rises over the securing projection during assembly or removal of the bezel, the inner peripheral portion of the assembly member is elastically deformed so as to come to near the outer peripheral portion. The deformation can be performed since the annular groove is formed between the inner peripheral portion and the outer peripheral portion. Since the inner peripheral portion having the securing portion is elastically deformed as described above, the securing portion rises over the securing projection as it escapes. Therefore, it is possible to suppress that the securing portion and the securing projection are eroded by interference between them, whether the robustness is the same between the securing portion and the securing projection, or different between them.
    In addition, the inner peripheral portion of the assembly member sandwiched by the middle part and the bezel adopts the elastically deformed state when the bezel is mounted according to the procedure described above. As a result, the securing portion is resiliently pressed on the annular convex portion by the elastic force of the inner peripheral portion, and a reaction force thereto is added to the bezel, thereby maintaining the telescope. in an immobile state.
    In the timepiece according to one embodiment of the present invention, the assembly member may comprise a plurality of notches in communication with the annular groove, and the inner peripheral portion may be divided into several portions in one direction. circumferential assembly member, by the notches.
    In the embodiment, the internal peripheral elements divided into several portions are not affected by the peripheral elements adjacent to each other, with the notches interposed between them, so that the elastic deformation can be performed more easily when the bezel is mounted on or removed from the caseband. Therefore, the assembly / disassembly of the bezel relative to the caseband can be performed more easily.
    Also in the timepiece according to one embodiment of the present invention, so that the assembly member does not move in the direction of the thickness of the bezel, a concave portion provided on one portions that are the bezel and the outer peripheral portion can fit a convex portion provided on the other of these parts. In addition, several convex portions and several concave portions may be provided.
    Since the assembly member is held so as not to move in the direction of the thickness of the bezel by the convexo-concave adjustment in the embodiment, it is not necessary to fix the assembly member to the bezel by means of an adhesive or a fastener for holding the assembly member. Since the assembly member is not attached to the telescope, the assembly member can be rotated by an angle different from the angle of rotation of the telescope when the assembly member is rotated in accordance with the actuation in rotation of the telescope. In addition, since the assembly member can be removed from the bezel, the assembly member can be replaced during an interview.
    Also in the timepiece according to one embodiment of the present invention, the bezel may comprise at least one hole opening at the inner peripheral concave portion, the assembly member may comprise a projection at the same time. number as the hole, and the projection and the hole can be adjusted to each other.
    As the hole of the bezel is adjusted to the projection of the assembly member in the embodiment, the assembly member can be rotated by the same angle of rotation as the bezel when the body of assembly is rotatably operated.
    The timepiece according to one embodiment of the present invention may further comprise ratchet arresting means for holding the bezel in a rotatably indexed position, in which the ratchet arresting means may comprise a ratchet coupling portion formed by a plurality of projections and a plurality of recesses formed side by side in the circumferential direction of the assembly member at an end surface of the outer circumferential portion which faces the middle part, and a ratchet member pressed on the ratchet coupling portion by an elastic force, which is engaged with and disengaged from the ratchet coupling portion.
    In the embodiment, the ratchet member may be pressed onto the ratchet engagement portion by the resilient force of a helical spring provided in addition to the ratchet member. When the ratchet member is formed by a leaf spring instead of the above, it is possible to press the ratchet member onto the ratchet coupling portion by the resilient force of the ratchet member itself.
    The assembly member whose rotation is locked relative to the bezel is doubled as part of the ratchet stop member in the timepiece in which the assembly member rotates. same angle of rotation as the bezel in the embodiment, so that the relative position between indications added to the surface of the bezel and the ratchet coupling portion is maintained correctly without experiencing any shift regardless of the actuation in rotation of the telescope.
    According to the invention, it is possible to prevent the attachment projection of the middle part and the securing portion of the assembly member meshing with the projection so as to maintain the bezel on the middle of the case. to be eroded and it is possible to suppress a decrease in the interference of subjection even when the telescope is mounted and removed for maintenance so that the reliability as to the maintenance of the state where the telescope is mounted on the caseband can be maintained. In addition, since the assembly member is sandwiched by the caseband and the bezel in the state where the inner peripheral portion of the assembly member is elastically deformed, there is an advantage which is that the tremor the bezel can be prevented and a rotational torque can be calibrated without using a dedicated lining material.

The annular convex portion 31 has a concave support portion 32 formed in an open state at its end and at its inner periphery . A rear surface of the periphery of the transparent glass 22 is in contact with the bottom surface of the concave support portion 32, and the transparent glass 22 is attached to the inner side of the annular convex portion 31 in a liquid-tight manner. by means of the packing 24 interposed between a peripheral surface of the transparent ice-cream 22 and the concave support portion 32. In this way, the annular convex portion 31 is provided so as to surround the transparent ice-cream 22.
    A securing protrusion 33 is formed on an outer periphery of the annular convex portion 31. The securing projection 33 extends in a circumferential direction of the annular convex portion 31 and is formed continuously around, for example, the outer periphery of the annular convex portion 31. The protruding dimension of the securing projection 33 is preferably, for example, 0.6 mm ± 0.1 mm.
    As shown in FIG. 4, the securing projection 33 includes a first slope 33a and a second slope 33b. The first slope 33a is a surface closer to the end of the annular convex portion 31 than the second slope 33b with respect to a root of the annular convex portion 31, which is inclined so that the securing projection 33 comes to near the root side of the annular convex portion 31 being inclined toward an end surface side thereof. The second slope 33b is a surface closer to the root of the annular convex portion 31 than the first slope 33a with respect to the root of the annular convex portion 31, which is inclined so that the securing projection 33 moves away. the root side of the annular convex portion 31 being inclined toward an end surface side thereof. As a result, the securing projection 33 is formed with a narrowing shape. The second slope 33b is used as a securing surface.
    The middle 21a a convex portion 34 and a concave groove 35 surrounding the root portion of the annular convex portion 31. The convex portion 34 protrudes from the front surface of the housing 12 so as to be formed into a ring shape. The concave groove 35 is limited by the convex portion 34 and the annular convex portion 31 so as to be ring-shaped, being open towards the front side of the housing 12. The middle part 21 has an annular shoulder portion 36 at a corner portion between the concave groove 35 and the root portion of the annular convex portion 31. Accordingly, a concave annular securing portion 31a (see Fig. 4) bounded by the annular shoulder portion 36 and the securing projection 33 is formed on a peripheral surface of the annular convex portion 31.
    A bezel 41 is disposed on the front surface side of the housing 12 so as to be maneuvered in rotation. As shown in FIG. 1, the bezel 41 has a ring shape and has an internal diameter that is larger than the diameter of the transparent glass 22. The bezel 41 has indications 42 given on its surface. In addition, protrusions and recesses 43 to prevent a user's fingers from slipping when the telescope is rotated by the user are formed around the telescope 41.
    The bezel 41 is made, for example, of the same kind of metal as the middle part 21, including an inner peripheral concave portion 44, a concave adjustment portion 45, at least one hole 46, a lid portion 47 and a convex insertion portion 48 as shown in FIG. 3 and in fig. 4.
    The inner peripheral concave portion 44 is formed continuously about the bezel 41 in a circumferential direction, while opening on an interior space surrounded by the bezel 41 and a rear surface of the bezel 41. The concave adjustment portion 45 is formed continuously around the bezel 41 in the circumferential direction, while opening towards a vertical surface limiting the inner peripheral concave portion 44 in the direction of the thickness of the bezel 41.
    The hole 46 is provided so as to open at the level of the inner peripheral concave portion 44. Precisely, the hole 46 is provided so as to open at a horizontal surface curving continuously from the vertical surface and limiting the inner peripheral concave portion 44. The horizontal surface may be a slope as well as a surface with a shoulder. Although only one hole 46 is shown, two holes are provided at 180 ° from each other in the circumferential direction of the bezel 41 in the present embodiment. When several holes are provided, they are provided at a distance from each other at equal intervals in the circumferential direction of the bezel 41. It is also possible to provide the holes 46 so that they open at the level of the vertical surface.
    The cover portion 47 is a portion which projects towards the center of the bezel 41, with respect to the inner peripheral concave portion 44, so as to define the minimum internal diameter of the bezel 41 and to cover the end of the annular convex portion 31. The convex insertion portion 48 is a ring-shaped portion formed on the rear surface of the bezel 41 so as to be inserted into a portion of the concave groove 35.
    As shown in FIGS. 2 to 4, an assembly member 51 is held in the bezel 41 so as not to disassociate, and the bezel 41 is mounted on the middle part 21 by means of the assembly member 51 so to be maneuvered in rotation.
    The assembly member 51 is a one-piece molded part made of a material that can be elastically deformed, for example a synthetic resin such as plastic having elasticity, which is formed in form ring as shown in fig. 6 and in fig. 7. As shown in figs. 3 to 7, the assembly member 51 comprises an outer peripheral portion 52, a base portion 53, an inner peripheral portion 54, notches 55, a securing portion 56, projections 57 and a convex portion d adjustment 58.
    The outer peripheral portion 52 is a portion placed in the inner peripheral concave portion 44 so as to be in contact with the vertical surface limiting the inner peripheral concave portion 44. The convex portion of adjustment 58 is projecting from the outer periphery of the outer peripheral portion 52. The convex adjustment portion 58 is formed continuously around the outer peripheral portion 52. The convex adjustment portion 58 is to be adjusted in the concave adjustment portion 45.
    The base portion 53 is formed to be continued by the outer peripheral portion 52. The base portion 53 has a flat surface 53a in contact with the horizontal surface limiting the inner peripheral concave portion 44. The projections 57 protrude from the flat surface 53a, are as much as the holes 46 and have the same positions as these holes 46. The projections 57 are to be adjusted in the holes 46.
    The inner peripheral portion 54 is continued by the base portion 53 with an annular groove 59 formed between the inner peripheral portion 54 and the outer peripheral portion 52. As a result, the inner peripheral portion 54 and the outer peripheral portion 52 are connected to each other by means of the base portion 53. FIG. 5 is a view showing a cross section of a portion of the constituent assembly member of the watch of FIG. 1. As shown in fig. 5, the width of the annular groove 59 increases gradually as one moves away from the base portion 53.
    The length of the inner peripheral portion 54 is shorter than the length of the outer peripheral portion 52. FIG. 6 is a perspective view showing the constituent assembly member of the watch of FIG. 1 seen from behind. Fig. 7 is a perspective view showing the constituent assembly member of the watch of FIG. 1 seen from the front. The inner peripheral portion 54 is divided into several portions in the circumferential direction of the fastener 51 by a plurality of notches 55 in communication with the annular groove 59 and provided at equal intervals in the circumferential direction of the fastener 51 as shown in FIG. 6 and in fig. 7. The inner peripheral portion 54 may be elastically deformed in the direction of a closer approximation and a distance from the outer peripheral portion 52, and the elastic deformation is permitted by the annular groove 59. In addition, as the inner peripheral portion 54 is divided into several portions by respective notches 55, the elastic deformation can be further facilitated.
    The securing portion 56 is projecting at an end portion of the inner peripheral portion 54 as well as towards a lateral surface that is not in front of the outer peripheral portion 52. The portion The fastening portion 56 is formed continuously around the inner peripheral portion 54. The securing portion 56 is a portion intended to fit the concave securing portion 31a of the middle part 21 as well as to engage the second slope 33b of the securing projection 33 from the root portion of the annular convex portion 31.
    As shown in FIG. 5, the securing portion 56 includes a sloping surface 56a and a securing surface 56b. The sloped surface 56a is formed in a sloping or arcuate surface. The securing surface 56b is formed at a slope similar to the second slope 33b of the securing projection 33.
    The assembly member 51 is mounted on the bezel 41 by adjusting the respective projections 57 respectively in the holes 46 of the bezel 41 and by convexo-concave adjustment of the convex portion adjustment 58 in the concave portion 45 of the bezel 41. The mounted state is shown in FIG. 3 and in fig. 4. The assembly member 51 can be held so as not to move in the direction of the thickness of the bezel 41 by means of the convexo-concave adjustment mentioned above. Therefore, it is not necessary to use an adhesive or a fastener to maintain the fastening state of the fastener 51 relative to the bezel 41.
    In the assembly state mentioned above, the outer peripheral portion 52 of the connecting member 51 is disposed in the inner peripheral concave portion 44 of the bezel 41. The outer periphery of the outer peripheral portion 52 is in contact with the vertical surface limiting the inner circumferential concave portion 44 in a vertically standing state without being adhered to the vertical surface, and the flat surface 53a of the base portion 53 is in contact with the horizontal surface limiting the portion concave inner device 44 without being glued to the horizontal surface.
    In addition, the end of the outer peripheral portion 52 protrudes from the rear surface of the bezel 41, in the assembled state. In addition, the inner peripheral portion 54 of the assembly member 51 is inclined relative to the outer peripheral portion 52, in the mounted state.
    The assembly member 51 is held by the adjustment of the convex portion adjustment 58 in the concave adjustment portion 45 so as not to dissociate from the bezel 41. In addition, the body assembly 51 is held so as not to move in the direction of the thickness of the bezel 41 by the contact of the flat surface 53a on the horizontal surface and the convexo-concave adjustment mentioned above. The assembly member 51 is positioned by adjusting the projections 57 in the holes 46 so as not to move in the circumferential direction of the telescope 41.
    The bezel 41 is mounted on the middle part 21 through the assembly member 51 held in the manner described above. The operation is performed by covering the annular convex portion 31 with the bezel 41 so that the assembly member 51 surrounds at least the outer periphery of the annular convex portion 31 of the middle part 21 and by pressing the bezel 41.
    In this case, firstly, the inner peripheral portion 54 is elastically deformed so as to be close to the outer peripheral portion 52 when the securing portion 56 of the assembly member 51 comes into contact with the outer periphery of the annular convex portion 31. The securing portion 56 comes into contact with the securing projection 33 of the annular convex portion 31 when pressing the bezel 41 is performed, so that the inner peripheral portion 54 is more elastically deformed. Therefore, the securing portion 56 rises over the fastening projection 33.
    At this moment, the first slope 33a of the fastening projection 33 touches the sloped surface 56a of the securing portion 56. Therefore, the pressing of the bezel 41 is not stopped by the fact that the securing portion 56 is taken up by the securing projection 33. In addition, the inner peripheral portion 54 is divided into a plurality of portions by the respective indents 55 and can be easily elastically deformed. As a result, the securing portion 56 can easily mount over the securing projection 33 by guiding the first slope 33a and the sloped surface 56a.
    [0054] Just after the securing portion 56 is mounted over the securing projection 33, the end of the outer peripheral portion 52 of the fastener 51 touches a bottom surface of the concave channel. 35. Consequently, the pressing movement of the telescope 41 is stopped.
    In addition to the foregoing, the securing portion 56 enters the concave securing portion 31a of the annular convex portion 31 as the inner peripheral portion 54 is returned to a right upper oblique direction in FIG. 3, due to the elastic force just after the rise, and the securing surface 56b of the securing portion 56 is engaged with the second slope 33b (securing surface) of the securing projection 33 in a it can be trapped from the root side of the annular convex portion 31. In this way, the bezel 41 is positioned in the direction of the thickness of the housing 12 so as to be mounted on the middle part 21. It is preferable that the outer peripheral portion 52 which touches the bottom surface of the concave groove 35 is elastically deformed in the assembled state described above, since the securing between the securing portion 56 and the securing projection 33 becomes more stable, and the assembled state of the bezel 41 becomes more stable.
    According to the assembly described above, the convex insertion portion 48 of the bezel 41 enters the concave groove 35 of the middle part 21 and adjusts to the inner periphery of the convex portion 34. Therefore, the bezel 41 is prevented from moving in the radial direction of the middle part 21. In addition, the cover portion 47 of the bezel 41 covers the end surface of the annular convex portion 31 formed in the middle part 21 and is arranged so as to be close a peripheral edge of the transparent ice 22. It is also preferable to allow the end surface of the annular convex portion 31 to be discovered between the inner periphery of the cover portion 47 and the peripheral edge of the transparent ice 22 at the end. by means of a suppression of the cover portion 47 or a narrowing of the projecting width of the telescope 41 in the centripetal direction.
    In the state where the bezel 41 is mounted on the middle part 21 as described above, the assembly member 51 is sandwiched between the annular convex portion 31 of the middle part 21 and the bezel 41, and the peripheral portion internal 54 retains elastic deformation. Consequently, the securing portion 56 is elastically pressed on the outer periphery of the annular convex portion 31 due to the elastic force of the inner peripheral portion 54, as well as a reaction force thereof on the telescope 41.
    Due to the reaction force, the bezel 41 is held so as not to jiggle in the radial direction. In addition, the force for rotating the bezel 41 is calibrated by a frictional gripping force between the outer periphery of the annular convex portion 31 and the inner peripheral portion 54 which elastically contacts it. The prevention of the shaking of the bezel 41 and the calibration of the force to rotate the telescope 41 can be achieved by the use of the assembly member 51, without requiring a dedicated part to achieve them.
    In the present embodiment, the projections 57 of the assembly member 51 are respectively mounted in the two holes 46 of the bezel 41. Therefore, when the bezel 41 is rotated by the user , the assembly member 51 is pivoted around the annular convex portion 31 of the same angle of rotation as the bezel 41.
    In the case of a maintenance operation of the periphery of the bezel 41, an external force that can remove the bezel 41 can be applied to the bezel 41 to remove the bezel 41 of the middle part 21.
    Therefore, the inner peripheral portion 54 of the connecting member 51 is elastically deformed so as to be closer to the outer peripheral portion 52. In this case, as the inner peripheral portion 54 is shorter than the portion external device 52 in accordance with the height of the annular shoulder portion 36 of the middle part 21, the end does not touch or rub the bottom surface of the concave groove 35 in accordance with an elastic deformation of the inner peripheral portion 54. As a result, it is certain that the inner peripheral portion 54 is elastically deformed.
    When the securing portion 56 rises over the attachment projection 33 of the annular convex portion 31 in accordance with an elastic deformation of the inner peripheral portion 54, the bezel 41 is dissociated from the middle part 21. At this at the moment, the securing portion 56 can easily mount over the securing projection 33 by guiding the second slope 33b of the securing projection 33 and the securing surface 56b of the portion In addition, the inner peripheral portion 54 is divided into a plurality of portions by respective notches 55 and may be deformed more easily.
    The bezel 41, the annular convex portion 31 of the middle part 21 and the assembly member 51 are cleaned in the state where the bezel 41 is removed, the maintenance of the periphery of the bezel 41 can be realized . In addition, the assembly member 51 can be replaced in addition to cleaning, if necessary, which allows maintenance around the bezel 41.
    As described above, when the bezel 41 is mounted on and removed from the middle part 21, the securing portion 56 of the assembly member 51 rises over the attachment projection 33 of the annular convex portion. 31. At this time, the inner peripheral portion 54 of the connecting member 51 is elastically deformed so as to be close to the outer peripheral portion 52. In other words, the securing portion 56 rises above the securing projection 33 while escaping therefrom with the elastic deformation of the inner peripheral portion 54 having the securing portion 56. Therefore, it is possible to suppress that the securing portion 56 and the projection of 33 are eroded, whether the strength is the same or different from each other, even though the securing portion 56 and the securing projection 33 interferes with each other. with each other when mounting and removing the telescope 41.
    Therefore, a decrease in the interference of subjection between the securing portion 56 and the securing projection 33 in the state where the bezel 41 is mounted on the middle part 21 can be suppressed. Therefore, the reliability of maintaining the state where the bezel 41 is mounted on the middle part 21 can be retained even if the mounting / dismounting of the bezel 41 is repeated.

Since components of the second embodiment are the same as those of the first embodiment except for the following explanations, identical components or components having the same function as in the first embodiment are designated by the same reference numbers only in the first embodiment and explanations thereof are omitted.
    In the second embodiment, the holes of the bezel 41 and the projections 57 of the assembly member 51 to be adapted in the holes described in the first embodiment are absent. Therefore, the bezel 41 and the assembly member 51 which is not bonded to it, can slide and move relatively in the circumferential direction. The other components, that is to say the components that are not described above, are identical to those of the first embodiment, including the components not shown in FIG. 8 and in fig. 9.
    Therefore, the problems of the present invention can also be solved with the second embodiment for the reason explained for the first embodiment. In addition, the concave adjustment portion 45 of the bezel 41 and the convex adjustment portion 58 of the assembly member 51 which is not attached to the bezel 41 by means of an adhesive can slide at the of the convexo-concave fit between them. Therefore, when following the bezel 41 rotated, the assembly member 51 is pivoted, the assembly member 51 has the possibility to be rotated by an angle different from the rotation angle of the bezel 41.
    FIG. 10 is a perspective view corresponding to FIG. 7 and shows a constituent assembly member of a watch according to a third embodiment of the present invention. Since components of the third embodiment are the same as those of the first embodiment except for the following explanations, the same components or components having the same functions as in the first embodiment are designated by the same reference numbers only in the first embodiment and explanations thereof are omitted.
    In the third embodiment, the inner peripheral portion 54 of the assembly member 51 is not divided into several portions and is formed continuously around the circumference in the circumferential direction. Other components are the same as those of the first embodiment, including components not shown in FIG. 10.
    Therefore, the problems of the present invention can be solved also in the case of the third embodiment for the reason explained for the first embodiment.
    FIG. 11 is a view showing a cross section corresponding to FIG. 3 and shows a watch according to a fourth embodiment of the present invention. Fig. 12 is a view showing a cross-section of a portion of an assembly member constituting the watch of FIG. 11. As components of the fourth embodiment are the same as those of the first embodiment except for the explanations below, the same components or components having the same functions as in the first embodiment of FIG. embodiment are designated by the same reference numbers as in the first embodiment and explanations thereof are omitted.
    The watch 11 according to the fourth embodiment further comprises pawl stop means 61 provided for holding the bezel 41 in a rotatably indexed position, in which the convex insertion portion 48 of the bezel 41 and the convex portion 34 of the middle part 21 mentioned for the first embodiment are omitted.
    As shown in FIG. 11, the pawl stop means 61 comprise, for example, a ratchet coupling portion 62, a pawl member 63 and a coil spring 64.
    The ratchet coupling portion 62 is formed at an end surface of the outer peripheral portion 52 which touches the bottom surface of the concave groove 35 provided in the middle part 21 as shown in FIG. 12. The ratchet coupling portion 62 is formed by a plurality of projections and recesses alternately arranged in the circumferential direction of the connecting member 51. Each convex portion 62a (see Fig. 12) of the coupling portion The ratchet 62 is triangular in shape and protrudes towards the bottom surface of the concave groove 35 as it tapers. Further, each concave portion 62b (see Fig. 12) of the ratchet coupling portion 62 formed between adjacent convex triangular portions 62a widens toward the bottom surface of the concave groove 35.
    As shown in FIG. 11, a housing groove 38 opening at the bottom surface of the concave groove 35 is formed in the middle part 21. The housing groove 38 is formed, for example, by a circular vertical hole. The ratchet member 63 and the coil spring 64 are housed inside the accommodation groove 38.
    The ratchet member 63 consists, for example, of a steel ball. The ratchet member 63 can move in an axial direction of the housing groove 38 and is prevented from escaping from the housing groove 38 by an opening edge portion 38a narrowing the opening of the accommodation groove 38. The coil spring 64 urges the ratchet member 63 with its elastic force. The biasing causes a portion of the pawl member 63 to protrude from the housing groove 38, and a protuberance is pressed onto the ratchet coupling portion 62.
    The projection of the pawl member 63 may be freely engaged with and disengaged from the pawl coupling portion 62, and the bezel 41 is held so as not to rotate inadvertently by the coupling. When the bezel 41 is actuated in rotation, the pawl member 63 is pushed by the convex portions 62a of the ratchet coupling portion 62 and is pushed back inside the housing groove 38 against the the biasing force of the coil spring 64. Therefore, the ratchet member 63 is uncoupled from the ratchet coupling portion 62, so that the rotation of the bezel 41 is continued. Just after this, the pawl member 63 is pressed onto the concave portion 62b of the ratchet coupling portion 62 by the biasing force of the coil spring 64, thereby engaging the ratchet coupling portion 62 with the ratchet portion 62. ratchet member 63.
    Therefore, when the user stops the rotational actuation in a state where the bezel 41 is rotated by any angle, the bezel 41 can be held in a position (indexed position) where the actuation in rotation of the telescope 41 is stopped by the ratchet arresting means 61. As the engagement / disengagement between the pawl member 63 and the ratchet coupling portion 62 is repeated with the rotational actuation of the ratchet member 61. telescope 41, the perception of the measurement can be given by the impact noises resulting from the engagement / uncoupling.
    In the fourth embodiment, the assembly member 51 is rotated by the same angle of rotation as the bezel 41 by the adjustment between the projections 57 and the holes 46. In the watch 11 according to the fourth In one embodiment, the assembly member 51 doubles as a part of the ratchet locking means 61 as previously described. Consequently, the relation as to the position between indications added on the surface of the telescope 41 and the pawl coupling portion 62 does not know any shift whatever the actuation in rotation of the telescope 41.
    Components other than the components described above in the fourth embodiment are the same as those of the first embodiment, including components not shown in FIG. 11 and in fig. 12.
    Therefore, the problems of the present invention can also be solved in the case of the fourth embodiment for the reason explained for the first embodiment.
