    BACKGROUND OF THE INVENTION
    1. Field of the invention
    The present invention relates to a timepiece such as a portable timepiece containing, inside a housing, a display body that can be moved by the manipulation of an element outside the housing .
    2. Description of the state of the art
    In conventional timepieces, it is known to provide the timepiece with an internal rotating ring, such as a flange, arranged to be rotatable around the peripheral edge of the dial in the outer casing and an actuating member rotating this ring from outside the outer casing (see, for example, JP-A-2010-139399 (Patent Document 1)).
    In the timepiece of Patent Document 1, the actuating element, which causes the inner rotating ring to rotate with it, has a shaft portion which passes through a fixed pipe. to the outer casing, and a head portion intended to be manipulated in rotation, which is arranged without discontinuity in the extension of this shaft portion and disposed outside the outer casing. The internal diameter of the pipe has no variation, but is fixed, and the outer diameter of the shaft portion has no variation and is also fixed. In order to seal between the pipe and the shaft portion, a sealing member, such as a liner held in contact with the inner periphery of the pipe, is mounted on the shaft portion.
    On its rear face, the internal rotating ring has teeth (drive gear) arranged in the peripheral direction, and a drive transmission gear engaged with these teeth is provided on the shaft portion in the outer casing. Thus, by virtue of the fact that the drive transmission gear is in engagement with the teeth of the inner rotary ring, when the head portion of the actuating element is rotated, the inner rotary ring is in turn rotated. Therefore, it is possible to move the display of the internal rotating ring relative to the dial and hands indicating the time.
    However, no particular means is adopted to keep the inner rotating ring in an arbitrary rotation position. Thus, in the assembly according to which, even if the mutual grip of the teeth of the drive transmission gear with those of the inner rotary ring is maintained at other times than during the operation of the drive element. When actuated, the rotation of the actuating element is suppressed by the frictional engagement force between the sealing member and the inner peripheral surface of the pipe. Therefore, it is possible to suppress any involuntary rotation of the internal rotating ring.
    In this case, an adjustment is made so that the clamping force of the sealed element held between the pipe having no change in internal diameter and the pipe having no change in outer diameter is important (in part). other terms, so that the degree of elastic deformation of the sealing element is increased), so that it is possible to increase the frictional engagement force between this sealing member and the inner peripheral surface of pipe.
    [0007] No particular load is applied to the inner rotating ring, and this inner rotating ring is of a diameter much larger than that of the drive gear. Thus, the rotation required on the part of the rotary actuating element to rotate the inner rotary ring by a predefined angle is such that the rotary actuating element must be strongly manipulated by the user, so that to make a very important rotation.
    In the context of this operation, when the frictional engagement force is strong, the manipulation in rotation of the actuating element becomes difficult. In addition, with the rotation of the actuating element, the outer periphery of the sealing element slides on the inner peripheral surface of the pipe, which promotes the wear of this sealing element. Thus, wear components (hereinafter referred to as "wear debris") accumulate between the sealing member and the inner peripheral surface of the pipe, so that degradation of the sealing performance is to be feared. .
    SUMMARY OF THE INVENTION
    An object of the present invention is to provide a timepiece which, while being able to avoid any malfunction of the display body in the housing, can facilitate the rotation of the actuating element, causing joint actuation of the display body therewith, and which has a high level of reliability in terms of sealing performance around the actuating element.
    In order to achieve the above purpose, provision is made, according to the present invention, a timepiece provided with a housing having a through hole, a display body having a display and which is housed in the housing so as to be able to move this display, a pipe attached to the through hole, an actuating member having a head portion for rotational manipulation, disposed outside the housing, and a shaft portion inserted so as to being rotatable relative to the pipe and movable in the axial direction of the pipe, and arranged to move between an operative position where the display body is actuated jointly by rotational manipulation of the head portion and a position in which the display body is held, and a ring-shaped liner disposed between the pipe and the shaft portion in an elastically deformed state, thereby tightens the interface between the pipe and the shaft portion, wherein one of the pipe and the shaft portion has a first annular contact surface, a second annular contact surface whose diameter is different from the diameter formed by the first annular contact surface, and an annular slope extending between the first and second annular contact surfaces; the other one of the pipe and the shaft portion has an opposite annular surface opposite to each of the aforementioned surfaces; the liner protrudes from the opposite annular surface and is mounted on the other one of the pipe and the shaft portion; and
    The packing is brought, in the state in which the actuating element is disposed in the operative position, in contact with that of the first and second annular contact surfaces having a wider gap between itself and the opposite annular surface and,
    The lining is brought, in the state in which the actuating element is disposed in the adjustment position, in contact with the annular contact surface forming, between itself and the opposite annular surface, a thinner gap than the above-mentioned gap.
    In the timepiece of the present invention, the head portion of the actuating element is held outside the housing and is pushed and pulled, so that the actuating element is moved in the direction in which its shaft portion extends between the operative position and the adjustment position and, with this, the relative positions of the shaft portion and the pipe into which it is inserted are changed. Therefore, the liner contacts one of the first annular contact surface and the second annular contact surface, providing sealing conditions for the interface between the pipe and the shaft portion of the d-element. actuation.
    More specifically, when it is necessary to jointly move the display body, the actuating element is disposed in the operating position. Due to this arrangement of the actuating element, the first annular contact surface belonging to one of the pipe and the shaft portion, and the opposite annular surface belonging to the other one of the pipe and the portion Shafts maintain the liner protruding out of the opposite annular surface into an elastically deformed state, sealing the interface between the shaft portion and the pipe. When it is not necessary to move the display body together, the actuating element is disposed in the adjustment position. Due to this arrangement of the actuating element, the second annular contact surface belonging to one of the pipe and the shaft portion and the opposite annular surface belonging to the other one of the pipe and the portion of the The shaft maintains the liner protruding out of the opposite annular surface into a resiliently deformed state, sealing the interface between the shaft portion and the pipe.
    The diameter formed by the first annular contact surface and the diameter formed by the second annular contact surface differ from each other; in the state where the actuating element is disposed in operative position, the liner is brought into contact with the surface, among the first and second annular contact surfaces, which forms a larger gap between itself and the surface opposite annulus, and the diameter of the liner is increased so as to reduce the clamping force, thus ensuring a sealed state around the actuating element. In the state where the actuating element is disposed in the position of setting, the liner is brought into contact with the surface, among the first and second annular contact surfaces, which forms a thinner gap between itself and the opposite annular surface, and the diameter of the liner is increased to reduce the clamping force, thus ensuring a sealed state around the actuating element.
    Thus, in comparison with the seal in operative position, in the adjustment position, the seal undergoes a stronger elastic deformation, and the degree of proximity in the contact between this seal and the annular contact surface is improved, so it is possible to improve the reliability of the sealing properties around the actuating element. With this, as the degree of proximity is improved, the frictional engagement force between the liner and the annular contact surface in contact therewith increases. Because of the resistance based on this mutual engagement force, it is difficult to easily rotate the actuating element involuntarily. Thus, it is possible to eliminate a malfunction of the display body due to an involuntary rotation of the actuating element while the timepiece is worn.
    Conversely, in comparison with the lining at the adjustment position, the operating position, the lining undergoes a lower elastic deformation, and the degree of proximity at the contact between the liner and the annular contact surface decreases, so that the seal around the actuating element deteriorates in the range where the required performance is maintained. However, with the reduction of the degree of proximity, the resistance against rotation of the actuating element decreases as the frictional engagement force between the liner and the annular contact surface in contact therewith decreases. Therefore, it is possible to facilitate the rotational manipulation of the actuating element when the display body is operated together.
    In this manipulation in rotation, the liner slides on the annular contact surface of larger diameter; however, the degree of proximity of the liner to the contact surface is reduced, so that wear of the liner due to slippage is eliminated. As a result, the service life of the packing is increased. At the same time, the wear residues of the lining are reduced with the elimination of wear, and it is possible to eliminate a degradation of the performance in terms of sealing due to these residues, so that in this respect also it is possible to improve the reliability of the seal around the actuating element.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
    The first embodiment of the present invention will be described with reference to FIGS. 1 to 4.
    In figs. 1 to 3, number 11 indicates a timepiece such as a portable timepiece, more specifically, a waterproof wristwatch. The wristwatch 11 comprises a housing 12 constituting the outer element thereof.
    As shown in FIGS. 2 and 3, in the housing 12, are housed the required elements such as a dial 13, a movement controlling the movement of the time display hands 14, and a display body 17.
    The dial 13 is circular, and has, in its peripheral part, a scale indicating the time 13a shown in FIG. 1. The dial 13 may be a digital display type dial that displays the scale of time display through a liquid crystal display. The hour display hands 14 are constituted at least by the hour hand and that of the minutes chosen from the set formed by the hour hand, the minute hand and the seconds hand.
    As shown in FIG. 1, a ring 16 is mounted on the housing 12 in the direction of the display at 3 o'clock of the wristwatch 11. The ring 16 is rotated outside the casing 12. Therefore, the rotation of the casing 16 is communicated to a drive train (not shown) belonging to the movement 15 to rotate, for example, the minute hand and the position of the minute hand is set.
    The display body 17 is formed, for example, of synthetic resin, and is of a ring-like configuration in a plan view, as shown in FIG. 1. The outer diameter of the display body 17 is larger than the diameter of the dial 13, and the internal diameter of the display body 17 is smaller than the diameter of the dial 13. The display body 17 is arranged to it is possible to turn in the circumferential direction of the dial 13. As shown in FIGS. 2 and 3, the inner peripheral portion of the display body 17 covers the surface of the peripheral portion of the dial 13.
    As shown in FIGS. 2 and 3, the thickness of the display body 17 increases progressively from the inner periphery to the outer periphery. The inclined and annular surface of the display body 17 thus formed is used as the display surface, and a display 17a is provided on this surface, as shown in FIG. 1. The display 17a consists, for example, of graduations arranged at equal intervals along the peripheral direction of the display body 17 by printing or the like. By changing the relative positions of the display 17a moved to a predefined position by the rotation of the display body 17 and the hands indicating the time 14, it is possible to obtain a stopwatch function for measuring a period of time which has elapsed since the measurement of a predetermined time.
    As described above, it is desirable that the display body 17 be of a ring-like configuration according to the plan view; however, this should not be interpreted restrictively. In the case where the display body 17 is of a ring-like configuration in plan view, it may be of endless configuration in plan view or of a C-shaped assembly, with its ends being mutually opposed. The display 17a of the display body 17 is not limited to graduations; it may also consist of a plurality of display regions divided by different colors from each other. Alternatively, the display 17a may consist of a plurality of display regions united with symbols drawn thereon (for example, a sun symbol indicating the time of day, and a moon symbol indicating the hour after the sunset). In addition, instead of providing the stopwatch function, the display 17a may be that of a directional display allowing a simple measurement of direction.
    As shown in Figs. 2 to 4, the display body 17 has, on its rear face, an integrated gear part 18. The driven gear portion 18 has portions formed of recesses and ridges arranged alternately in the peripheral direction of the display body 17; these ridges and depressions extend in the radial direction of the display body 17. The driven gear portion 18 is outside the outer periphery of the dial 13, and surrounds this outer periphery.
    As shown in FIGS. 2 and 3, the housing 12 is formed by attaching, for example, a liquid-tight transparent cover 22 to a surface in the thickness direction of an annular housing band 21 and attaching a housing bottom 23 sealed to at the other surface in the direction of the thickness of the housing strip 21. It is desirable that the housing strip 21 is formed of a metal such as stainless steel or titanium.
    The transparent cover 22 is, for example, circular, and constitutes the front face of the timepiece 11. The transparent cover 22 consists of a transparent element, for example, a transparent glass, through which it It is possible to see the dial 13 and the display body 17. The caseback 23 constitutes the rear surface of the timepiece 11. The caseback 23 is made of metal, synthetic resin or the like. In figs. 2 and 3, the numbers 24 and 25 respectively show the annular seals held between the housing strip 21 and the transparent cover 22 and between the housing strip 21 and the housing back 23 to maintain the liquid tightness of the housing 12 .
    As shown in FIGS. 2 and 3, the housing strip 21 has an annular protrusion 26 projecting towards the interior space. The rear surface of the peripheral portion of the transparent cover 22 is held in contact with, and is supported by, the annular protuberance 26. This annular protrusion 26 covers the surface of the outer peripheral portion of the display body 17. Thus, the body of the 17 is retained by the dial 13 and the annular protuberance 26 so as not to move in the thickness direction of the timepiece 11. In addition, the inner peripheral surface 21a of the housing strip 21, extending at right angles to the rear face of the annular protrusion 26, is close to the outer peripheral surface of the display body 17, so that the display body 17 is held without being able to move in its radial direction.
    The housing strip 21 has a through hole 27 shown in FIGS. 2 and 3 arranged in a position offset from the mounting position of the ring 16, for example, 2 hours. A pipe 28 is inserted into this through hole 27 to be attached to the housing 12. When both the housing strip 21 and the pipe 28 are made of metal, the pipe 28 is attached to the housing strip 21 by soldering. When at least one of the housing strip 21 and the pipe 28 is formed of synthetic resin, the pipe 28 is attached to the housing strip 21 with an adhesive. The pipe 28 extends in the radial direction of the display body 17.
    The pipe 28 has the shape of a floor cylinder having a large diameter portion 28a and a small diameter portion 28b. The small diameter portion 28b of this pipe 28 is passed through the through hole 27. The large diameter portion 28a of the pipe 28 is disposed outside the housing 12, the nearest end surface thereof. the small diameter portion 28b being kept in contact with the outer peripheral surface of the housing 12.
    The inner peripheral surface of the pipe 28 has a first annular contact surface 29, a second annular contact surface 30 offset in the axial direction of the pipe 28 relative to the first annular contact surface 29, and an annular slope 31 .
    The diameter (inner diameter) of the first annular contact surface 29 is different from the diameter (internal diameter) of the second annular contact surface 30. More specifically, in the first embodiment, the diameter (internal diameter) the second annular contact surface 30 is larger than the diameter (internal diameter) of the first annular contact surface 29; conversely, the diameter (inner diameter) of the first annular contact surface 29 is smaller than the diameter (internal diameter) of the second annular contact surface 30.
    The annular slope 31 is provided so as to extend between the first annular contact surface 29 and the second annular contact surface 30. With this annular slope 31 serving as a border, the first annular contact surface 29 is arranged. on the inner face of the housing 12, and the second annular contact surface 30 is provided on the outer side of the housing 12. In the first embodiment, the first annular contact surface 29 constitutes the inner peripheral surface of the small portion. 28b diameter of the pipe 28, and the second annular contact surface 30 constitutes the inner peripheral surface of the large diameter portion 28a of the pipe 28.
    In the first embodiment, the first annular contact surface 29, the annular slope 31, and the second annular contact surface 30, which are arranged without discontinuity in the extension with each other, are formed for each other. extend over the entire length of the pipe 28, that is to say from one longitudinal end thereof to the other. However, such implementation should not be interpreted restrictively; each of the above surfaces may be arranged to occupy only a portion in the axial direction of the pipe 28.
    In FIG. 1, the number 41 indicates an actuating element. The actuating element 41 is actuated outside the housing 12 to move the display 17a; it moves together the display body 17, and the display body 17 is rotated by this joint movement. As shown in figs. 2 and 3, the actuating element 41 is made of metal, and is provided with a head portion 42 and a shaft portion 43.
    The head portion 42 is formed as a cap having a peripheral wall similar to a ring and an end wall closing over this peripheral wall. The depth A and the internal diameter (the diameter formed by the inner peripheral surface of the peripheral wall) of this head 42 are greater than the entire length B of the large diameter portion 28a of the pipe 28 and the diameter formed by the outer peripheral surface of the large diameter portion 28a. A knurled portion for preventing slippage of the operator's fingers when this head portion 42 is rotated is provided on the outer peripheral surface of the peripheral wall of the head portion 42 by knurling.
    The shaft portion 43 extends integrally from the central portion of the rear surface of the end wall of the head portion 42, and this shaft portion 43 is longer than the entire length of the portion of the large diameter 28a. The cross-sectional view of the assembly of the distal end portion 43a with the shaft portion 43 in the direction orthogonal to the axial direction of the shaft portion 43 is non-circular, having for example a cross-sectional section. D as shown in fig. 4. Therefore, the shaft portion 43 has a staging 43b.
    The diameter of the outer peripheral surface of the portion other than the distal end portion 43a, i.e. the diameter of the portion from the origin of the shaft portion 43 to the portion distal end 43a having a length indicated by the dimension C in FIG. 2 is fixed. The aforesaid portion is longer than the entire length of the pipe 28, and the outer peripheral surface of this portion is used as the opposite annular surface 44. In the case where a drive gear piece 45 is superimposed, for example on the distal end surface of the shaft portion 43 and attached thereto, it is possible to use the entire outer circumferential surface as the opposite annular surface 44.
    The shaft portion 43 of the actuating element 41 is rotatably mounted relative to the pipe 28 and is inserted so as to be able to move in the axial direction of the pipe 28. Therefore, the head portion 42 of the actuating element 41 is disposed outside the housing 12 while covering the large diameter portion 28a of the pipe 28. At the same time, a thin gap is formed between the first annular contact surface 29 and the opposite annular surface 44, through the pipe 28 and the shaft portion 43 inserted therein, and a wider gap than this gap is formed between the first annular contact surface 29 and the opposing annular surface 44. machining this surface, it is desirable that the diameter of the opposite annular surface 44 is fixed; however, provided that the condition of ensuring the above gap relationship is satisfied, the diameter of the opposite annular surface 44 may be different with a trim mentioned below serving as a border.
    Mounted on the distal end portion 43a of the shaft portion 43 of the actuating member 41 is a drive gear piece 45 transmitting the rotation of the actuating member 41 to 17. Specifically, the drive gear piece 45 has a clamping engagement hole 45a of an assembly corresponding to the sectional configuration of the distal end portion 43a. After clamping this tight fitting hole 45a with the distal end portion 43a, an elastic ring 46 is mounted on an open groove in the outer peripheral surface of the distal end portion 43a, whereby the drive gear piece 45 is held between the elastic ring 46 and the step 43b, and the drive gear piece 45 is rotatably mounted relative to the distal end portion 43a. The teeth 45b belonging to the drive gear piece 45 are constantly held in mutual engagement with the driven gear portion 18 of the display body 17. That is, during the push operation and pulling the actuating member 41 described below, the position where the driving gear piece 45 and the driven gear portion 18 are in mutual engagement moves in the radial direction of the driving body. display 17, while maintaining the gear relationship itself.
    The shaft portion 43 has, in its intermediate portion taken in its longitudinal direction, a continuous peripheral annular mounting groove 47. In a snap fit with this mounting groove 47, a ring-like liner 48 is mounted to protrude out of the outer circumferential surface (the opposite annular surface 44) of the shaft portion 43. pad 48 is formed of an elastically deformable material such as synthetic rubber or a synthetic resin. This liner 48 is held between the pipe 28 and the shaft portion 43 inserted therein while being elastically deformed. As a result, the seal 48 seals the interface between the pipe 28 and the shaft portion 43.
    By the operation of pushing and pulling, the actuating element 41 can be moved between an operative position and an adjustment position, defined so as to be offset from each other in the axial direction. of the pipe 28 along the axial direction of the pipe 28 extending in the radial direction of the display body 17. The actuating element 41 is illustrated in the depressed position, corresponding to the adjustment position in FIG. 2, and the actuating element 41 is illustrated in the extended position corresponding to the operative position in FIG. 3.
    The adjustment position is a position intended to keep the display body 17 in position, so as to prevent it from being involuntarily rotated. When the actuating element 41 is disposed in this adjustment position, the seal 48 has its reduced diameter, and is brought into contact with the first annular contact surface 29 constituting the inner peripheral surface of the small-diameter portion 28b. of the hose 28. The frictional engagement force between the first annular contact surface 29 and the packing 48 is strong, so that involuntary rotation of the display body 17 and the actuating element 41 is removed, which keeps the display body 17 motionless.
    The operative position is a position in which the user or the like voluntarily rotates the head portion of the actuating member 41 to rotate the display body 17 in conjunction therewith. When the actuating element 41 is disposed in this operative position, the liner 48 is increased in diameter and is brought into contact with the second annular contact surface 30 constituting the inner peripheral surface of the large diameter portion 28a of the pipe. 28. The frictional engagement force between the second annular contact surface 30 and the gasket 48 is small, so that the actuating element 41 can be easily rotated.
    In the following, the procedures for rotating the display body 17 will be described.
    First, in the state where the liner 48 is in contact with the first annular contact surface 29 constituting the inner peripheral surface of the small diameter portion 28b of the pipe 28 (shown in Fig. 2) , the head portion 42 of the actuating element 41 is gripped with the fingers, and pulled out of the housing 12, and the actuating element 41 is disposed in the operative position, as illustrated in FIG. . 3.
    By this movement of the actuating element 41, the seal 48 out of the thin gap between the shaft portion 43 and the small diameter portion 28b, and enters the wide gap between the part d the shaft 43 and the large-diameter portion 28a for coming into contact with the second annular contact surface 30. That is, when it leaves the first annular contact surface 29, the seal 48 sees its diameter. increased, and comes into contact with the second annular contact surface 30 constituting the inner peripheral surface of the large diameter portion 28a of the hose 28. As a result, a state is reached in which the clamping force of the packing 48 (in in other words, the degree of elastic deformation of the liner 48) is low.
    In this case, the resistance of the gasket 48 against the movement of the actuating element 41 is reduced by a reduction in the diameter of the gasket 48. The difference in terms of resistance is detected by the fingers, which is which makes it possible to know that the actuating element 41 has been pulled into the operative position. Even in the state where the actuating member 41 is in the operative position, the packing 48 retains elastic deformation, so that the sealing performance between the pipe 28 and the shaft portion 43 is ensured.
    In this state, the shaft portion 43 is rotated in conjunction with the head portion 42, so that the drive gear piece 45 is also rotated with the shaft portion 43. With this, the rotation of the drive gear piece 45 is transmitted to the display body 17 via the mutual gearing engagement between the display body 17 and the driven gear portion 18. Thus, the display body 17 is rotated together with the rotation of the actuating element 41 so that it is possible to move the display 17a thereof to a desired position.
    As described above, in the state where the actuating element 41 is disposed in its operative position, the seal 48 sees its increased diameter. Compared to the state in which the liner 48 is reduced in diameter due to being in contact with the first annular contact surface 29, as shown in FIG. 2, in this state the elastic deformation of the liner 48 is weakened. As a result, the contact force between the liner 48 and the second annular contact surface 30 is small, and is smaller than the frictional engagement force therebetween. The frictional engagement force is a resistance to the rotation of the actuating element 41. Thus, it is possible to easily actuate the actuating element 41 in rotation, when it is in its position. operational position.
    The lateral surface of the drive gear piece 45 is opposed to the distal end of the small diameter portion 28b of the hose 28. Thus, when the actuating member 41 is threatened with traction excessive, the drive gear piece 45 is captured by the distal end of the small diameter portion 28b, and the hose 28 serves as a stop. As a result, the shaft portion 43 of the actuating element 41 is pulled out of the pipe 28, and the actuating element 41 is not detached from the housing 12.
    After the display body 17 has been rotated as desired, the actuating element 41 is pressed into the interior of the housing 12, and is moved from the use position to the adjustment position illustrated by FIG. fig. 2. This driving operation is stopped by the peripheral wall of the head portion 42 when it comes into contact with the outer lateral surface 21b of the housing strip 21.
    Through the movement of the actuating element 41, the seal 48 out of the wide gap between the shaft portion 43 and the large diameter portion 28a, and enters the thin gap between the shaft portion 43 and the inner peripheral surface of the small diameter portion 28b for engaging the first annular contact surface 29. That is, as it exits the second surface With the annular contact 30, the packing 48 is reduced in diameter by the annular slope 31 and, in this state, comes into contact with the first annular contact surface 29 constituting the inner peripheral surface of the small-diameter portion 28b of the pipe 28. As a result, one arrives in a state in which the clamping force of the liner 48 is large. Thanks to the contact between the gasket 48 and the first annular contact surface 29, sealing is ensured between the pipe 28 and the shaft portion 43.
    As described above, in the state where the actuating element 41 is in its adjustment position, the seal 48 sees its reduced diameter. Compared to the state where the liner 48 is kept in contact with the second annular contact surface 30 to see its increased diameter, as shown in FIG. 3, in this state the elastic deformation of the liner 48 is enhanced. As a result, the contact force between the liner 48 and the first annular contact surface 29 is strong, and is greater than their mutual frictional engagement force. Thus, a high sealing performance is provided between the pipe 28 and the shaft portion 43. At the same time, as a large resistance force to the rotation of the actuating element 41 is ensured, it is possible to eliminate any malfunction where the actuating element 41 is involuntarily actuated in rotation to rotate the display body 17.
    The first annular contact surface 29 and the second annular contact surface 30 form no staggering, but are arranged without discontinuity in the extension of one another to the other via the annular slope 31 which extends between them. Therefore, the diameter reduction of the packing 48 accompanying the depression of the actuating element 41 is carried out without difficulty, and there is no fear to have on the fact that the seal 48 is scratched by the staging and generates residues. At the same time, because of the low frictional engagement force between the second annular contact surface 30 and the gasket 48, as described above, it is possible to reduce the wear of the gasket 48 when turns the display body 17. Thus, the life of the seal 48 is improved.
    In addition, as described above, the seal 48 does not easily produce residues resulting from cuts or abrasive wear. Thus, it is also possible to prevent a degradation of the sealing properties because of such residues which would be caused to be wedged between the pipe 28 and the lining 48.
    As described above, according to the first embodiment, it is possible to provide a wristwatch 11 which can allow easy actuation of the actuating element 41 jointly moving the display body 17, and which is of high reliability in terms of sealing properties around the actuating element 41 while being able to eliminate any malfunction of the display body 17 in the housing 12.
    In addition, in the first embodiment, by pushing and pulling the actuating element 41 to selectively change the clamping force of the gasket 48, it is possible to operate the actuating element 41. in the same way as the crown 16, which is desirable. In addition, when the actuating member 41 is depressed, the clamping force of the liner 48 is large, as previously described. Therefore, when the actuating element 41 is involuntarily pressed, for example, while the timepiece 11 is being carried, it is possible to maintain a state in which the clamping force of the lining 48 is large, so that the timepiece is very reliable in terms of unintentional rotation suppression of the actuating element.
    In addition, the annular slope 31 is machined on the pipe 28 without discontinuity with respect to the first annular contact surface 29, and the second annular contact surface 30 has a larger diameter than the diameter formed by the first annular contact surface 29, so that it is possible to realize, without increasing the number of components, an assembly in which the clamping force of the lining 48 is selectively modified by an operation of displacement of the actuating element 41. In addition, when machining the mounting groove 47 on which the packing 48 is mounted, the shaft portion 43 does not limit the operating space, and the space around the shaft portion constitutes the operating space, which results in satisfactory machinability; in addition, it is not necessary to provide a special component for retaining the seal 48 during assembly of the seal 48.
    Figs. 5-7 show the second embodiment of the present invention. The timepiece according to the second embodiment has the same type of assembly as the first embodiment with the exception of what is described below. Thus, components that have the same type of assembly or the same function as those of the timepiece of the first embodiment described above are indicated by the same reference numerals, but will not be described in more detail. .
    The second embodiment differs from the first embodiment in the positioning of the first annular contact surface 29 and the second annular contact surface 30 constituting the inner peripheral surface of the pipe 28.
    That is to say that in the second embodiment, the first annular contact surface 29 is arranged on the outer face of the housing 12 with the annular slope 31 serving as a border. At the same time, the second annular contact surface 30 is arranged on the inner face of the housing with the annular slope 31 serving as a border. The inside diameter of the pipe 28 formed by the first annular contact surface 29 is smaller than the inside diameter of the pipe 28 formed by the second annular contact surface 30; conversely, the inside diameter of the pipe 28 formed by the second annular contact surface 30 is greater than the inside diameter of the pipe 28 formed by the first annular contact surface 29.
    In addition, in the second embodiment, there is provided a pulse element such as a coil spring 49 pressing the actuating element 41 towards the outside of the housing 12. The coil spring 49 is maintained in a compressed state between the wall portion forming the border between the large diameter portion 28a and the small diameter portion 28b of the pipe 28 and the end wall of the head portion 42. The coil spring arrangement 49 does not is not limited to that described above. For example, it is also possible to maintain the coil spring 49 in a compressed state between the end surface of the pipe 28 opposite the end wall of the head portion 42 and the end wall of the head portion 42. In addition, it is also possible to arrange the coil spring 49 so as to surround the outer periphery of the large diameter portion 28a of the pipe 28, keeping the coil spring 49 in a compressed state between the outer side surface 21b of the strip housing 21 and the end wall of the head portion 42.
    Apart from the assembly described above, the present embodiment is the same as the first embodiment, including the assembly not shown in FIGS. 5 to 7 .
    In the following, the procedures for rotating the display body 17 in the second embodiment will be described.
    First, in the state (illustrated in Fig. 6) where the liner 48 is in contact with the first annular contact surface 29 constituting the inner peripheral surface of the small diameter portion 28b of the hose 28 , the head portion 42 of the actuating element 41 is gripped by the fingers, and the actuating element 41 is pressed into the interior of the housing 12 against the thrust force of the coil spring 49, which which sets up the actuating element 41 in the operative position illustrated in FIG. 7. This driving operation is stopped when the peripheral wall of the head portion 42 is brought into contact with the outer lateral surface 21b of the housing strip 21.
    By this movement of the actuating element 41, the seal 48 out of the thin gap between the shaft portion 43 and the inner peripheral surface of the small diameter portion 28b, and enters the gap. wide between the shaft portion 43 and the large diameter portion 28a to engage the second annular contact surface 30. That is, when it leaves the first annular contact surface 29, the packing 48 has its diameter increased due to the elastic force, and it comes into contact with the second annular contact surface 30 constituting the inner peripheral surface of the large diameter portion 28a of the pipe 28. Therefore, one arrives in a state wherein the clamping force of the liner 48 is low.
    When the actuating element 41 is thus disposed in its operative position, the seal 48 retains its elastic deformation, so that the seal between the pipe 28 and the shaft portion 43 is ensured.
    In this state, the shaft portion 43 is rotated in conjunction with the head portion 42, and the drive gear 45 together with the shaft portion 43. At the same time, the rotation of the drive gear piece 45 is transmitted to the display body 17 through the mutual gearing engagement between the display body 17 and the driven gear portion 18. The display 17 is rotated in conjunction with the rotation of the actuating element 41, so that it is possible to move the display 17a thereof to a desired position.
    As described above, in the state where the actuating element 41 is depressed to be disposed in its operative position, the seal 48 sees its increased diameter. Compared to the state where the liner 48 is in contact with the first annular contact surface 29 to see its reduced diameter, as illustrated in FIG. 6, in this state the elastic deformation of the liner 48 is lower. As a result, the contact force between the liner 48 and the second annular contact surface 30 is small, and their mutual frictional engagement force is low. The frictional engagement force is a resistance force to the rotation of the actuating element 41. Thus, it is possible to easily rotate the actuating element 41 when it is in its position. operational state.
    After the display body 17 has been rotated as desired, the actuating element 41 is moved outwardly of the housing 12, and is moved from the operative position to the adjustment position illustrated by FIG. . 6.
    By this movement of the actuating element 41, the seal 48 out of the wide gap between the shaft portion 43 and the large diameter portion 28a, and enters the thin gap between the portion of the shaft 43 and the inner circumferential surface of the small diameter portion 28b to engage the first annular contact surface 29. That is, as it exits the second annular contact surface 30, the liner 48 is reduced in diameter by the annular slope 31 and, in this state, it comes into contact with the first annular contact surface 29 constituting the inner peripheral surface of the small diameter portion 28b of the hose 28. a state is reached in which the clamping force of the packing 48 is large. Due to the contact between the gasket 48 and the first annular contact surface 29, the seal between the pipe 28 and the shaft portion 43 is ensured.
    As described above, in the state where the actuating element 41 is disposed at the adjustment position, the seal 48 sees its reduced diameter. Compared to the state where the liner 48 is kept in contact with the second annular contact surface 30 to see its increased diameter as illustrated in FIG. 7, in this state the elastic deformation of the liner 48 is reinforced. Therefore, the contact force between the liner 48 and the first annular contact surface 29 is strong, and their mutual frictional engagement force is great. Thus, it ensures high sealing performance between the pipe 28 and the shaft portion 43. At the same time, since it ensures a significant resistance force against the rotation of the actuating element 41 it is possible to eliminate any malfunction where the actuating element 41 is involuntarily actuated in rotation to rotate the display body 17.
    As a consequence of the reduction of the diameter of the gasket 48, the resistance with respect to the movement of the actuating element 41 increases at the setting position. This feeling of resistance is detected by the fingers, so that it is possible to know whether or not the actuating element 41 has been pulled into the adjustment position.
    The lateral surface of the drive gear 45 is opposed to the distal end of the small diameter portion 28b of the hose 28. Therefore, when attempting to pull the drive member excessively 41 the drive gear piece 45 is captured by the distal end of the small diameter portion 28b, and the hose 28 serves as a stop. As a result, the shaft portion 43 of the actuating element 41 is pulled out of the pipe 28, and the actuating element 41 is not detached from the housing 12.
    The first annular contact surface 29 and the second annular contact surface 30 form no staggering, and are arranged without discontinuity with respect to each other via the annular slope 31. Thus, the diameter reduction of the packing 48 accompanying the traction of the actuating element 41 is performed without difficulty, and there is no fear to have on the fact that the seal 48 is scratched by the staging and produce a residue . At the same time, as described above, the frictional engagement force between the second annular contact surface 30 and the liner 48 is small, so that it is possible to reduce the wear of the liner 48 when the display body 17 is rotated. Thus, the service life of the packing 48 is improved.
    In addition, as described above, the packing 48 does not easily cause a production of residues resulting from cuts or abrasive wear. Thus, it is possible to prevent a degradation of the seal because of such residues that would be caused to be wedged between the pipe 28 and the seal 48.
    As described above, according to the second embodiment, although it is possible to eliminate any malfunction of the display body 17 in the housing 12, it is possible to easily actuate the actuating element. 41 moving together the display body 17, and to provide a wristwatch 11 which is very reliable in terms of sealing around the actuating element 41.
    In addition, the timepiece 11 according to the second embodiment is provided with a coil spring 49 pressing the actuating element 41 towards the outside of the housing 12. Thus, when it ceases to there is the driving force with respect to the actuating element 41 pushed into the operative position so as to reduce the clamping force of the seal 48, the actuating element 41 is automatically pushed towards the outside of the casing 12 because of the plating force of the coil spring 49 without having to perform especially the pulling operation of the actuating element 41. Therefore, the actuating element 41 is arranged, in the setting position, of in order to increase the clamping force of the packing 48, so that it is possible to eliminate any involuntary rotation of the actuating element 41 when, for example, the timepiece 11 is p COPE.
    FIG. 8 shows the third embodiment of the present invention. The timepiece according to the third embodiment has the same type of assembly as the first embodiment with the exception of what is described below. Thus, components that have the same type of assembly or the same function as those of the timepiece of the first embodiment described above are indicated by the same reference numbers, and will not be described in more detail. .
    In the third embodiment, the arrangement of the first annular contact surface 29, the second annular contact surface 30, and the annular slope 31, the arrangement of the opposite annular surface 44 opposite these surfaces, and the arrangement of the mounting groove 47 and the liner 48 are different from those of the first embodiment.
    That is to say that the first annular contact surface 29, the second annular contact surface 30, and the annular slope 31 extending between these contact surfaces are arranged on the shaft portion 43 of the actuating element 41. These surfaces constitute at least a portion of the outer peripheral surface of the shaft portion 43.
    The diameter of the shaft portion 43 formed by the second annular contact surface 30 is greater than the diameter of the shaft portion 43 formed by the first annular contact surface 29. The first annular contact surface 29 is arranged on the distal end side of the shaft portion 43, i.e. on the inside of the housing 12, the annular slope 31 serving as a border; conversely, the second annular contact surface 30 is provided on the proximal end side of the shaft portion 43, i.e. on the outer face of the housing 12, the annular slope 31 serving as a border.
    The opposite annular surface 44 constitutes at least a portion of the inner peripheral surface of the pipe 28, and is arranged on the pipe 28. The diameter formed by this opposite annular surface 44 (the internal diameter of the pipe 28) has no change, and is fixed. Thus, a thin gap is formed between the first annular contact surface 29 and the opposite annular surface 44 by the pipe 28 and the shaft portion 43 inserted therein, and a wider gap than this gap is formed between the first annular contact surface 29 and the opposite annular surface 44. It is desirable that the internal diameter of the pipe 28 constituting the opposite annular surface 44 is fixed from the point of view of the machining of this surface; however, the diameter of the opposite annular surface 44 may be different with the trim 48 described below serving as a border as long as the condition of ensuring the gap relationship is satisfied.
    A mounting groove 47 is formed in the pipe 28. The gasket 48 is nested by clamping with the mounting groove 47, and is mounted on the pipe 28 so as to protrude beyond the opposite annular surface 44. This packing 48 is held between the pipe 28 and the shaft portion 43, and is elastically deformed in a compressed state, which serves to seal between the pipe 28 and the shaft portion 43.
    The rest of the assembly other than what has been described above, including the assembly not shown in FIG. 8, is identical to that of the first embodiment.
    In the third embodiment, to actuate the display body 17 in rotation, the head portion of the actuating element 41 is first pinched, and the actuating element 41 is pulled towards the outside of the housing 12 from the state shown in FIG. 8 to be arranged in the operative position. Then, in this state, the actuating member 41 is rotated, so that the display body 17 can be rotated in the housing 12 in conjunction therewith. In this case, when the actuating element 41 is pulled out, the position of the shaft portion 43 with respect to the opposite annular surface 44 and the seal 48 is changed.
    More specifically, the second annular contact surface 30 is detached from the gasket 48, and the first annular contact surface 29 is brought into contact with the gasket 48. As a result, the gasket 48 is increased in diameter, and is positioned in the wide gap between the first annular contact surface 29 and the opposite annular surface 44 and, at the same time, brought into contact with the first annular contact surface 29. Therefore, sealing is ensured between the pipe 28 and the shaft portion 43. In the state where the liner 48 thus sees its increased diameter, the frictional engagement force between the liner 48 and the first annular contact surface 29 is low. Thus, it is possible to rotate the actuating member 41 with little force in the operative position, where the display body 17 is moved together.
    After the display body 17 has been rotated, the actuating element 41, which has already been pulled, is pressed into the interior of the housing 12, and is arranged in the adjustment position. When the actuating element 41 is depressed, the relative position of the shaft portion 43 with respect to the opposite annular surface 44 and the seal 48 is changed.
    More specifically, the first annular contact surface 29 is detached from the seal 48, and the second annular contact surface 30 comes into contact with the seal 48. Therefore, the seal 48 has its reduced diameter, and is positioned in the thin gap between the second annular contact surface 30 and the opposite annular surface 44; at the same time, it is brought into contact with the second annular contact surface 30. Therefore, the seal is provided between the pipe 28 and the shaft portion 43.
    In the state where the actuating element 41 is thus arranged in the adjustment position, the frictional engagement force between the gasket 48 and the second annular contact surface 30 is strong. Thus, the performance in terms of sealing around the actuating element 41 is high. At the same time, it is possible to effectively suppress unintentional rotation of the actuating element 41 and, with this, it is possible to prevent any risk of the display body 17 being inadvertently rotated.
    In addition, as described above, the contact pressure of the gasket 48 with respect to the first annular contact surface 29 at the operating position is small, so that it is possible to eliminate the wear of the packing 48 accompanying the rotation of the actuating element 41. At the same time, when the actuating element 41 is pressed from the operational position to the adjustment position, it is possible to reduce the diameter without difficulty. of the packing 48 in the expanded diameter state without scratching it with the annular slope 31. Thus, it is possible to eliminate any degradation of performance in terms of sealing due to wear residues and residues due to cuts of the filling 48.
    As described above, according to the third embodiment, although it is possible to eliminate any malfunction of the display body 17 in the housing 12, it is possible to provide a wristwatch 11 in which it It is possible to easily actuate the actuating element 41 displacing the display body 17 together with it, and which is very reliable in terms of sealing around the actuating element 41.
    The third embodiment described above is also applicable to a timepiece in which, as in the second embodiment, the display body 17 is moved together by rotating the actuating element. 41 in the state where it has been depressed into operative position, and in which, from this state, the actuating element 41 is pulled out of the housing 12 to move it into the adjustment position.
    In this case, the first annular contact surface 29 is arranged at the proximal side relative to the shaft portion 43, the annular slope 31 then serving as a border, that is to say on the face external of the housing 12, and the second annular contact surface 30 is arranged at the distal end side relative to the shaft portion 43, the annular slope 31 then serving as a border, that is to say on the inner face of the housing 12.
