    BACKGROUND OF THE INVENTION
    1. Domain
    The implementation of the present invention relates to a timepiece.
    2. Description of the prior art
    There are timepieces having a structure according to which, after the insertion of the movement provided with the hands and a dial in the middle part of the timepiece from the mounting direction of a bezel relative to the middle, the bezel is then fitted to the middle. As an example, such a structure has been disclosed in the Japanese patent application below where the middle and the bezel of a timepiece are fixed to each other using a mechanical screw (see JP-A-2002-189084).
    As a structure for the mutual fixing of a middle part and a bezel, apart from the fixing structure using mechanical screws as mentioned above, structures are known in which an engagement portion is provided at the heel of the bezel inserted in the middle part, and in which the engagement portion engages with the middle part using a bending force of the heel.
    [0004] However, in such a structure where the engagement portion is brought into engagement with the middle part by using the bending force of the heel of the bezel, since the number of times the bezel is mounted on the middle part and detached from it, that is to say the number of times the case is opened and then closed, increases, one can fear that the middle part or the bezel is scratched. In addition, in the event that a material subject to deformation such as gold or a hard material such as titanium is used for the bezel and the middle part, a structure in which the engagement portion would engage the middle part. using a bending force of the heel of the bezel would be rather unsuitable.
    SUMMARY OF THE INVENTION
    In view of the foregoing, an objective of an embodiment of the present invention is to make it possible to comfortably repeat the opening and closing of a bezel relative to the middle part, by achieving by therefore an improvement in terms of maintenance properties of a timepiece.
    According to a first embodiment of the invention, there is provided a timepiece comprising: a middle part which has an opening at its upper face, and has a housing within its internal peripheral part; a bezel to which a crystal is attached and which is mounted on the upper face of the caseband; a protuberance which is arranged at the level of a part of the bezel inserted inside the middle part and which projects in the direction of the internal peripheral part so that it does not penetrate into the housing; and a locking member which is rotatably mounted on the bezel, which can pivot between the top and the bottom of the protuberance by crossing the protuberance via an elastic deformation, and an upper part of which abuts against a ceiling of the housing and a lower part of which abuts against the protuberance in a state in which the bezel is mounted to the middle part so as to be engaged respectively with the middle part and the bezel.
    [0007] In this timepiece, the blocking member is rotatably mounted to the bezel. When the movement is inserted into the caseband and mounts the bezel to the caseband, a heel of the bezel is inserted in the caseband. At this time, the protuberance provided on the heel protrudes so as not to penetrate inside the housing, so that it does not easily interfere with the internal peripheral part of the middle part. In addition, at this time, the blocking member up to the bezel begins to penetrate inside the housing of the middle part. When the heel of the bezel is gradually force-fitted into the middle part, the protuberance of the bezel, which has been on top of the locking member, passes underneath while causing an elastic deformation of the latter so as to that he can temporarily sink into the housing. At this time, from an opposite point of view, the blocking member passes over the protuberance of the bezel while undergoing elastic deformation, and performs a rotation to pass from below to above the protuberance. . When it passes over the protuberance, the blocking member temporarily extends elastically, and, after being definitively passed above the protuberance, tends to regain its initial configuration under the effect of the stress of its own elastic restoring force. At this time, the upper part of the locking member is in abutment against the ceiling of the housing, and the lower part of the locking member is in abutment against the protuberance, with the result that the locking member is engaged respectively with the middle part and the bezel. Therefore, the bezel is mounted on the middle. The locking member is placed in a state in which it is housed between the bezel and the middle part.
    [0008] On the other hand, when the bezel is detached from the middle part, the protuberance provided on the heel of the bezel moves from below the locking member causing an elastic deformation of the locking member so that the locking member can temporarily sink into the housing. At this time, from an opposite point of view, the locking member passes over the protuberance of the bezel, and rotates from above to below the protuberance. Consequently, the mutual engagement between the blocking member, the middle part and the bezel is released, and the bezel can be detached from the middle part.
    According to a second embodiment of the invention, there is provided a timepiece according to the first embodiment, in which the bezel is provided with a support limiting the range of rotation of the locking member downwards , teile so that when the bezel is not mounted on the middle part and the bezel is placed in a horizontal state, the locking member is held in a predetermined position under the protuberance.
    [0010] In this timepiece, when the bezel is not mounted on the middle part and the bezel is placed horizontally, the range of downward rotation of the locking member is limited by the support , and the locking member is held in a predetermined position under the protuberance. Consequently, the locking member no longer dangles relative to the bezel. Therefore, when mounting the bezel to the middle part, it is possible to eliminate any interference from the blocking member with respect to the hands and the dial mounted to the movement.
    According to a third embodiment of the invention, there is provided a timepiece according to the first embodiment or the second embodiment, in which a pair of locking members is provided on each side according to the radial direction of the bezel.
    In this timepiece, when mounting the bezel to the middle part, the heel of the bezel is inserted into the middle part and is gradually force-fitted into it, while the locking member is engaged respectively with the middle part and the bezel on each side in the radial direction of the bezel. Therefore, the operation of mounting the bezel to the caseband is facilitated.
    According to a fourth embodiment of the invention, there is provided a timepiece according to the first embodiment or the second embodiment, in which the locking member is provided on one side only according to the radial direction of the bezel, and on the side of the bezel devoid of locking member, there is provided an engagement portion in direct engagement with the middle part.
    In this timepiece, the engagement portion on the side of the bezel devoid of the locking member is brought into direct engagement with the middle part, and then the side where the locking member is provided is fitted with force in the middle part, by engaging the blocking member respectively with the middle part and the bezel. The arrangement of a locking member only on one side in the radial direction of the bezel enables a reduction in the number of components compared to the case where a locking member is provided on each side in the radial direction.
    According to a fifth embodiment of the invention, there is provided a timepiece according to one of the first to the fourth embodiments, in which the housing ceiling is inclined relative to the upper face of the middle part , inwards in the radial direction of the caseband; and the protuberance has the shape of a section tapered outwardly in the radial direction of the bezel.
    In this timepiece, the ceiling of the housing of the middle part is inclined, so that the locking member can easily enter and leave the housing. In addition, the protrusion of the bezel is formed in a tapered configuration, with an outwardly decreasing section, so that it is easy for the locking member to pass over the protrusion. Therefore, the process of attaching / detaching the bezel from the middle part is facilitated.
    According to a sixth embodiment of the invention, there is provided a timepiece according to one of the first to the fifth embodiments, in which the locking member is provided with a projected growth part constituting a growth margin at the time of elastic deformation.
    In this timepiece, the locking member is provided with a protuberance constituting a growth margin at the moment of elastic deformation, so that, compared to the case where the protuberance is not provided, it is easier for the locking member to extend in the protrusion direction of the protrusion passing over the protrusion of the bezel.
    [0019] According to the implementation of the present invention, it is possible to comfortably repeat the opening and closing of the bezel relative to the middle part, making it possible to achieve an improvement in terms of the maintenance property of the part. clockwork.

    DESCRIPTION OF EMBODIMENTS
    [0021] In the following, an embodiment of the present invention will be described with reference to the drawings.
    [First embodiment]
    Referring to Figures 1 and 2, a timepiece 10 according to the present embodiment consists, for example, of a wristwatch, and has a middle part 12, a bezel 14 given by way of example for a bezel, a protuberance 16, and a locking member 18.
    The middle part 12 is a component of a timepiece which is open at its upper face, which has a housing 24 within an internal peripheral part 22, and in which a movement 26 is inserted from the face superior. At both ends of the middle part 12 of FIG. 1, fastening parts for bracelet 12A are respectively provided. A bracelet 32 is mounted to the bracelet attachment portion 12A via a spring pin 30. As illustrated in Figure 2, at a side surface of the middle part 12, a hole 12B is formed in which a shank 28A of. crown 28 is inserted. This hole 12B extends through the internal peripheral part 22 of the middle part 12. Through this hole 12B, the rod 28A of the crown 28 is connected to the movement 26 housed in the middle part 12.
    In Figures 2 and 3, the middle part 12 is provided with a dial housing 44 to have a dial 34 there. In the housing of the dial 44 are also arranged needles 35 mounted on the movement 26. Below the housing of the dial 44, there is provided a movement housing 46 for housing the movement 26. The movement housing 46 has a tubular shape conforming to the external configuration of the movement 26. Below the movement housing 46 is formed, for example, a female screw 12C for mounting a case back 36. Here, the underside, that is to say the “lower side” corresponds to the case back 36 (which is usually referred to as the back side) of part d 'watchmaking 10.
    In Figure 2, in the housing of the dial 44, the movement 26 is held in position by a casing ring 38. Between the case back 36 and the middle part 12 is provided a case back cover 40 for ensure the waterproof properties of the watch.
    The internal peripheral part 22 provided with the housing 24 is located in the internal periphery of the housing of the dial 44. When the timepiece 10 is seen, for example, in a plan view, the housing 24 extends to both at the top (at 12 o'clock on timepiece 10) and at the bottom (6 o'clock on timepiece 10). The housing 24 consists, for example, of a groove facing outward in the radial direction from the inner peripheral portion 22 of the middle part 12, and extends, for example, in a linear or arcuate fashion in the direction of the thickness of the middle part 12. This thickness direction is the lateral direction of the width when the timepiece is attached to the wrist; in other words, the direction connecting the "3 o'clock" and "9 o'clock" of dial 34. In the event that the timepiece 10 is not configured in a square but round shape, the housing 24 can be extend in the peripheral direction. In Figures 6 and 7, a ceiling 24A of the housing 24 is inclined vis-à-vis the upper face of the middle part 12 radially towards the inside of the middle part 12. Consequently, the ceiling 24A is oriented obliquely towards down relative to the center of the caseband 12. A base 24B of the housing 24 is formed at a lower level than the base 44B of the housing of the dial 44, and extends the inside of the caseband 12 in the radial direction to movement housing 46.
    In Figures 1, 2 and 4, the glass 42 as an example of crystal is fixed to the bezel 14, which is mounted on the upper face of the middle part 12. Between the bezel 14 and the middle part 12, is provided a bezel packing 48 to provide sealing properties. Figure 4 shows the bezel 14 when it is turned over. The bezel 14 has an edge 14A covering the middle part 12 and constituting a decorative surface in the periphery of the glass 42. In addition, the bezel 14 has a heel 14B such as a portion to be inserted inside the middle part 12. Ice is not limited to glass 42 and any other hard, transparent material could be suitable. For example, it can be made of a transparent resin.
    The bottom 24B of the housing 24 is formed at a lower level than the bottom 44B of the housing of the dial 44. In accordance with this fact, the part of the heel 14B on which the protuberance 16 is arranged protrudes downward ( the top in Figure 4) of the bezel 14 beyond this assembly part.
    Figures 6 and 7, the protrusion 16 is arranged on the heel 14B while the portion of the bezel 14 is inserted inside the middle part 12. It is an element projecting towards the internal peripheral part 22, so as not to penetrate inside the housing 24. The protuberance 16 is configured in a shape whose section is tapered (conical of decreasing diameter towards its distal end) outwards in the radial direction of the bezel. 14. In other words, the protrusion 16 has an inclined surface both seen from above and seen from below. As illustrated in Figure 1, the protuberance 16 is intended to extend, in a plan view of the timepiece 10, a smaller (shorter) distance than the housing 24 of the middle 12. As illustrated in the figures. Figures 7 (B) and 8 (B), the angle of inclination of the upper surface of the protrusion 16 is different from the inclination angle of the ceiling 24A of the housing 24, the distance between the protrusion 16 and the ceiling 24A of the housing 24 decreasing as one moves inward in the radial direction of the middle part 12.
    In Figures 2 and 4, the locking member 18 is rotatably mounted to the bezel 14, and passes over the protuberance 16 after having undergone an elastic deformation. Thus, it can pivot between a position located above the protuberance 16 and below it. In the state in which the bezel 14 has been fitted to the middle part 12, the upper part of this locking member 18 adjoins the ceiling of the housing 24, and its lower part adjoins the protuberance 16, with the result that the member locking 18 is mutually engaged with the middle part 12 and the bezel 14 respectively.
    More specifically, the locking member 18 is formed by folding, for example, of a metal wire in accordance with the external structure of the heel 14B of the bezel 14, for example, in a substantially C shape. wear at the middle part 12 and the bezel 14, it is desirable that the material of the locking member 18 be softer than the material of the parts of the middle part 12 and of the bezel 14 intended to be brought in contact with the locking member 18. At the central part in the width direction of the locking member 18, a protrusion 18A is formed, protruding from an insert part 18C described. below (in the direction of the depth of the housing 24 of the case 12). As shown in Figure 1, the protuberance 18A has a structure conforming to the protuberance 16 of the bezel 14 and the housing 24 of the middle part 12. The protrusion 18A extends over a length which is defined as being wider (longer). than that of the bezel 14 - that is to say the protuberance 16.
    At both ends of the locking member 18, are formed insert parts 18C by bending the two ends of the wire line inwardly in the direction of the width. Moreover, on the lateral surface of each heel 14B of the bezel 14, are formed, for example, two fixing holes 14C. By inserting the insert portions 18C of the locking member 18 into the fixing holes 14C, the locking member 18 is mounted on the bezel 14. The locking member 18 is rotatably mounted around the portion of 18C insertion. A pair of locking members 18 is provided on each side in the radial direction of the bezel 14. Correspondingly, the protuberances 16 of the bezel 14 and the housings 24 of the middle part 12 are also provided respectively in pairs.
    In addition, a support 50 is provided on each side in the width direction of the bezel 14 of the timepiece. The support 50 is a part limiting the amplitude of downward rotation of the locking member 18 so that the locking member 18 is held in a predetermined position under the protuberance 16 when the bezel 14 is not. mounted to the caseband 12 and to the bezel 14 is placed in the horizontal state. As shown in Figure 4, the support 50 is integrally formed with the heel 14B such that it projects outwardly from the heel 14B. The support 50 protrudes at least on the bottom (the top in Figure 4) of the insertion part 18C of the locking member 18 so as to abut against the locking member 18 in a position reached by slightly downward rotation of the locking member 18 when the bezel 14 is not mounted on the middle part 12 and is placed horizontally.
    As in the case of variant 1 shown in Figure 5, the locking member 18 may be provided with a flat protuberance 18B constituting a growth margin at the time of elastic deformation. This planar protuberance 18B is a part obtained by bending a part of the locking member 18 in a corrugated manner. For example, a pair or a plurality of planar protuberances are provided for a locking member 18.
    The locking member 18 and the fixing hole 14C can be formed as in the case of variant 2 shown in Figure 9A. In this holder 60, the insertion part 18C of the locking member 18 is configured to take a non-circular cross-sectional shape, for example, a rectangular cross-sectional shape, and the fixing hole 14C also has a cross-sectional shape. non-circular, such as, for example, a shape of elliptical configuration. The width of the fixing hole 14C is adjusted to be a little wider than the width of the insert part 18C. As illustrated in Fig. 9B, in this variation, the insertion part 18C is liable to interfere with the fixing hole 14C when the locking member 18 rotates to a certain degree. Also in this configuration, it is possible to limit the range of rotation of the locking member 18. In other words, the support for restricting the range of rotation of the locking member 18 can be made for such a structure. In addition, the support can be configured differently and have a distinct structure as long as it allows the range of rotation of the locking member 18 to be limited.
    (Operation)
    In the following, the operation of the present embodiment, having the structure described above, will be described. In Figures 6 to 8, in the timepiece 10 of the present embodiment, the locking member 18 is mounted on the bezel 14 so as to be able to rotate around the insertion part 18C. This locking member 18 can be easily mounted to the bezel 14 only by inserting the insertion part 18C into the fixing hole 14C of the bezel 14.
    The movement 26 to which the dial 34 and the needles 35 are mounted is housed in the middle part 12, and during the assembly of the bezel 14 to the middle part 12, the heel 14B of the bezel 14 is inserted into the middle part 12. At this time, the protuberance 16 provided on the heel 14B does not easily interfere with the internal peripheral part 22 of the middle part 12, so that wear due to the contact between the bezel 14 and the middle part 12 does not is not easily generated. In addition, at this moment, the locking member 18 mounts to the bezel 14 begins to penetrate inside the housing 24 of the middle part 12 while sliding on the bottom 44B of the housing of the dial 44 or on the bottom 24B of the housing 24. More specifically, the protuberance 18A of the locking member 18 begins to enter the housing 24.
    As illustrated in Figures 7 and 8, when the heel 14B of the bezel 14 is gradually force-fitted into the middle part 12, the protuberance 16 of the bezel, which was above the locking member 18 , passes under the locking member 18 (Fig. 8) while causing an elastic deformation of the locking member 18, so that the protuberance 18A of the locking member 18 can temporarily penetrate deeply through inside the housing 24 (Figure 7 (B)). At this time, from an opposite point of view, that is to say seen from the locking member 18, while the latter undergoes an elastic deformation, its protuberance 18A passes above the protuberance 16 of the bezel, and rotates from the bottom to the top of the protuberance 16.
    The locking member 18 is configured in a curved C-shape, so that by passing over the protuberance 16, it temporarily extends resiliently, and, after passing behind it , aspires to return to its initial configuration under the impulse of its own elastic return force. At this time, the upper part of the protuberance 18A of the locking member 18 is in abutment against the ceiling 24A of the housing 24, and the lower part of the locking member 18 is in abutment against the protuberance 16, with the result that the blocking member 18 is in mutual engagement with the middle part 12 and the bezel 14 respectively. Therefore, the bezel 14 is mounted to the middle part 12. The protrusion 18A passes beyond the protuberance 16 using the elastic deformation of the locking member 18, so that wear is probable. In addition, the protuberance 16 of the bezel 14 has a tapered configuration, of conical section, so that when the protrusion 18A of the locking member 18 passes over the protuberance 16 and tries to regain its configuration. initial under the impulse of its elastic return force, it is likely to come to rest against the protuberance 16.
    The angle of inclination of the upper surface of the protrusion 16 is different from the inclination angle of the ceiling 24A of the housing 24, and thus the distance between the protrusion 16 and the ceiling 24A of the housing 24 is reduced as one goes inward in the radial direction of the middle part 12. Therefore, when the protrusion 18A of the locking member 18 passes beyond the protuberance 16 and tries to return to its initial configuration under the impulse of its own elastic return force, the protuberance 18A is not only resting against the protuberance 16 but also against the ceiling 24A of the housing 24. Consequently, the locking member 18 does not not return to its natural state, but forcibly maintained in a state in which it remains somewhat elastically deformed. This helps to suppress any generation of noise. In addition, the protrusion 18A adjoins the top of the protrusion 16 due to the elastic return force of the locking member 18, and thus it is possible to exert a force on the downwardly oriented protrusion 16. Therefore, the bezel 14 can be pulled down from the middle part 12.
    In the present embodiment, a pair of locking members 18 is provided on each side in the radial direction of the bezel 14, so that, when mounting the bezel 14 to the middle part 12, in forging the heel 14B of the bezel 14 to enter the middle part 12, the locking member 18 is in mutual engagement respectively with the middle part 12 and the bezel 14 on each side in the radial direction of the bezel 14. Therefore, the operation of mounting the bezel 14 to the middle part 12 is facilitated.
    On the other hand, when removing the bezel 14 from the middle part 12, the protuberance 16 provided on the heel 14B of the bezel 14 moves from below to above the locking member 18, while causing an elastic deformation of the locking member 18, so that the locking member 18 can temporarily penetrate inside the housing 24. At this time, from the opposite point of view taken from the locking member. blocking 18, the latter passes behind the protuberance 16 of the bezel 14 and rotates from the top of the protuberance 16 towards the underside thereof. Consequently, the mutual engagement between the blocking member 18 and the middle part 12 and the bezel 14 is released, so that it is possible to remove the bezel 14 from the middle part 12.
    If the locking member 18 has been worn due to the fixing / disassembly of the bezel 18 relative to the middle part 12, it is only necessary to replace the locking member 18. Since the The locking member 18 is an inexpensive component formed by bending a wire line, replacement costs can be eliminated.
    As illustrated in Figure 2, when the bezel 14 is not mounted to the middle part 12 and the bezel 14 is arranged horizontally, the range of downward rotation of the locking member 18 is limited by the support 50, and the locking member 18 remains in its predetermined position under the protuberance 16. This helps to eliminate the fact that the locking member 18 can dangle relative to the bezel 14. Therefore, when mounting the bezel 14 on the middle part 12, it is possible to eliminate any interference between the locking member 18 and the hands and the dial mounted on the movement 26.
    In addition, as illustrated in Figures 7 and 8, the ceiling 24A of the housing 24 of the middle part 12 is inclined, so that the locking member 18 can easily enter the interior of the housing 24 and exit. of it. Since the protuberance 16 of the bezel 14 has a tapered shape of conical section, the locking member 18 can easily pass over the protuberance 16. Therefore, the attachment / disassembly of the bezel 14 relative to the middle part 12 is facilitated.
    The locking member 18 of variant 1 shown in Figure 5 is provided with a protuberance 18B constituting a growth margin at the time of elastic deformation, so that, compares to the case where there is no protuberance provided 18B, when the blocking member 18 passes above the protuberance 16 of the bezel 14, it can extend more easily in the direction in which the protuberance 16 extends.
    In this way, in the present embodiment, it is possible to comfortably repeat the opening and closing of the bezel 14 relative to the middle part 12, which makes it possible to achieve an improvement in terms of the properties of maintenance of timepiece.
    In the case where the bezel is attached to the middle part using a machine screw, a female screw for fixing the machine screw is blocked in the heel of the bezel, so that the bezel should have a width rather large, which makes it impossible to have a larger dial, and thus affects visibility. The caseband must also be provided with a through hole through which the screw must be passed, and to hide the screw, it is necessary to arrange the screw, for example, on the upper surface of the bracelet.
    On this aspect, in the present embodiment, there is no need to provide a machine screw, so that, compared to the case where a machine screw is used, the width of the edge of the telescope 14 can be relatively thinner. Thus, it is possible to employ a larger dial 34, thereby achieving an improvement in visibility. In addition, the locking member 18 is housed between the bezel 14 and the middle part 12 in order to avoid any loss in terms of space, so that no excess space is required inside the part. watchmaking 10. Therefore, it is also possible to guarantee the provision of a space for the bracelet 32 under the bezel 14.
    [Second embodiment]
    Figures 10 and 11, in a timepiece 20 according to the present embodiment, the locking member 18 is provided only on one side of the bezel 14 in the radial direction. For example, it is brought up (at 12 o'clock on dial 34) or down (at 6 o'clock on dial 34) of timepiece 20.
    On the side of the bezel 14 where no locking member 18 is provided, and more specifically, on the side in the radial direction of the bezel 14 opposite the protuberance 16, an engagement portion 52 is arranged so to come into direct engagement with a housing 25 of the middle part 12. The engagement portion 52 is arranged on the heel 14B. The engaging portion 52 is a protrusion configured such that it will penetrate the interior of the housing 25 while the outer surface of the heel 14B will be maintained in contact with the inner peripheral portion 22. The protrusion 16 engaged with the locking member 18 protrudes towards the inner peripheral part 22 of the middle part 12 so as not to penetrate inside the housing 24, while the engagement portion 52 protrudes towards a position where it enters the housing 25. In other words, the engagement portion 52 protrudes beyond the protuberance 16.
    As shown in FIG. 10, in the timepiece 20 of this embodiment, the engagement portion on the side of the bezel 14 devoid of the locking member 18 is in direct engagement with the middle part 12, and then, the side where the blocking member 18 is fitted is forced into the middle part 12, thus mutually engaging the blocking member 18 respectively with the middle part 12 and the bezel 14 (FIG. 11). The locking member 18 is provided on one side of the bezel 14 in the radial direction, so that, compared with the case where the locking members 18 are provided on each side in the radial direction, it is possible to reduce the number of components.
    The mutual engagement of the locking member 18, the middle part 12 and the bezel 14 and its release at the time of fixing / disassembling the bezel 14 is the same as that of the first embodiment. Parts which are the same as those in the first embodiment are indicated by the same reference numerals in the drawings, and their description will not be repeated.
