    Description
    BACKGROUND OF THE INVENTION Field of the Invention [0001] The invention relates to a watch, such as a wristwatch, in which a cell for electricity generation or light emission is provided in a module displaying the time or the like, and the cell is covered with a display plate. In particular, the invention relates to a watch in which a fixing configuration of the display plate is improved.
    STATE OF THE ART [0002] As is the state of the art, a watch is known in which a cell comprising a solar cell or electroluminescence and a translucent display plate covering them are arranged on the module (see, for example, FIG. Japanese Patent No. 4,398,555 [Patent Document 1]).
    In this state of the art, an auxiliary ring consisting of a resin molding product has a pair of cylindrical projections in a plurality of locations respectively on an upper surface of an outer peripheral portion thereof. , and has a projection on a lower surface thereof. The projections of the auxiliary ring are engaged with the module, and the auxiliary ring is attached to the module. With this, the display plate is configured as a thin plate by a synthetic resin such as a clear acrylic resin or a polycarbonate resin, and has a plurality of notches in the peripheral portion thereof. By engaging the notches with the cylindrical projections of the module, the display plate is attached to the auxiliary ring.
    In particular, the pair of cylindrical projections has a slot therebetween and they are shaped so as to be elastically deformable towards the slot. The notches in the display plate elastically deform a pair of cylindrical projections disposed therein in a direction approaching each other and are engaged with each other. Therefore, it is possible to fix the display plate in the state in which deflection or lateral rotation is prevented.
    In a watch according to this state of the art, since a length of a cylindrical projecting portion based on the upper surface of the outer peripheral portion of the auxiliary ring is short, the elastic deformation of the cylindrical protrusion is not easy, but rather difficult. In other words, a resilience of the cylindrical protrusion is extremely low. For this reason, the work of engaging the notches with the cylindrical protrusion by elastically deforming it and fixing the display plate to the auxiliary ring is painful.
    When assembling the watch, when the mounting of the display plate on the auxiliary ring is bad or the like, after removing the display plate, it performs a job relocation or work of replacing the display plate with a new one. This work is a rearrangement of the display board.
    In this work of rearrangement, it is first necessary to remove the display plate from the erroneous attachment of the upper part of the module using a tool such as a tweezers. In this case, since the elastic deformation of the cylindrical convex portion is difficult, as described above, the work of removing the display plate from the erroneous attachment is also naturally painful.
    In this way, in the watch of this state of the art, it is difficult to fix and easily remove the display plate to the auxiliary ring or the latter. In addition, the cylindrical protrusion, which is short in length and whose elastic deformation is not easy, is bent easily by exceeding the elastic limit due to the fixing of the display plate. When such a situation occurs, even if the rearrangement of the display plate is performed, it is difficult to fix the display plate in a suitable manner, and there is a great possibility of causing erroneous fixation of the plate display due to rearrangement.
    That is to say, this state of the art has a problem in that the work of fixing the display plate to the auxiliary ring and the work of rearranging the display plate are painful. , and there is a great possibility that an improper fixation of the display plate is generated due to the rearrangement of the display plate.
    DESCRIPTION OF THE INVENTION In order to solve the problem, according to the present invention, there is provided a watch, comprising a module; a cell attached to the module; an annular annular member when viewed from a plane which is attached to a peripheral portion of the module, protruding fastener portions formed at a plurality of locations of the annular member, and protruding fastener portions having contact portions which are located near the outer peripheral surface of the annular member; a display plate, which is arranged to cover the cell, has a plurality of grooves for receiving the protruding fastening portions, open towards the peripheral surface of the display plate, and a plurality of holding portions which subdivide the receiving grooves abut against the contact part in a state of elastic deformation, and engage the protruding fastening parts interposed therebetween in a direction perpendicular to the radial direction of the annular element, the protruding parts in the receiving grooves of the respective protruding fastening portions, and the display plate being attached to the annular member.
    In the present invention, when the module is implemented as an analog type watch, the module indicates a movement which causes a plurality of time display hands, and when it is implemented as a digital type watch, the module indicates an electronic circuit that drives a display that shows time (time) or the like.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0040] Hereinafter, a first embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6.
    The reference sign 1 in FIG. 1 shows a watch, for example a portable watch, in particular a wristwatch. The wristwatch 1 comprises an outer assembly of a watch 2, a module, for example a movement 11, a cell, for example a solar cell 15, an annular element 21, a display plate, for example a dial 31.
    The watch casing 2 comprises a housing 6 of metal or synthetic resin with a middle 4 and a bottom 5 and an ice 7. The bottom 5 is screwed and connected to the middle part 4. In addition, the housing 6 may have a one-piece configuration in which the middle 4 and the bottom 5 are integral. The ice 7 is mounted inside a bearing 4a formed in the middle part 4 in a liquid-tight manner.
    The outer member 6 has a flange 4b. The flange 4b illustrated in FIG. 1 is integral with the inner periphery of the middle 4, but may be a ring-shaped element molded separately from the body 4. The flange 4b has an inclined surface 4c, and the inclined surface 4c faces a peripheral surface portion back of the ice 7.
    The movement 11 is driven by the electrical energy generated by the solar cell 15 described later, and includes an accumulator for accumulating electrical energy, a capacitor or the like (not shown). Movement 11 has a circular shape when viewed from a plane. The movement 11 is incorporated in the outer watch assembly 2 with an annular element 21, a dial 31 or the like described later.
    The movement 11a has an engaging portion 12. The engaging portion 12 is provided at an upper surface side in a peripheral portion of the movement 11, and is, for example, formed in an upper surface portion a ring-shaped convex portion continued in a circumferential direction of the movement 11. Referring to FIG. 1, the engagement portion 12 is slightly deepened in a back side (a lower side) of the movement 11 relative to the upper surface 11a of the movement 11.
    The solar cell 15 is a cell in which a solar cell (not shown) acts as an electricity generating element generating electricity by photoelectric conversion is mounted on a substrate (not shown). The solar cell may be a crystalline system or an amorphous system. The solar cell 15 is of diameter slightly smaller than the diameter of the movement 11 and is fixed to the upper surface 11a of the movement 11 by using a bonding element 16. As adhesive element it is possible to very suitably use an adhesive tape to double sided, both sides of which are adhesive.
    The annular element 21 is formed of a synthetic resin, for example a molded product integrated in Duracon. The annular element 21 constitutes an annular shape when viewed from a plane and whose inside diameter is slightly greater than the diameter of the solar cell 15, and whose outer diameter is greater than the diameter of the movement 11. L annular member 21 has engagement grooves 22 which are open to the inner surface and the rear surface (a lower surface) thereof. The engagement grooves 22 are formed continuously in the circumferential direction of the annular ring member 21.
    In addition, the annular element 21 has recesses 23 and protruding fastening portions 25 of the same number as that of the upper surface 21a in a plurality of locations, as well as hook portions 29 (one of which is shown in Fig. 1) in a plurality of locations on the back surface.
    Referring to FIG. 2, the recesses 23 are provided in two places in the outer peripheral part of the annular element, for example in order to be separated by 180 degrees. In addition, the depressions 23 may be provided in three locations for each 120 degrees or they may be provided in four locations for each 90 degrees. The respective depressions 23 are respectively open to the upper surface 21a and the outer peripheral surface of the annular element 21, and have a first hollow portion 23a to a fourth hollow portion 23d (i.e., first to fourth hollow portions 23a to 23d) as shown in FIGS. 4 to 5.
    The first hollow portion 23a is parallel to the second hollow portion 23b. One end of each of the first hollow portion 23a and the second hollow portion 23b is open towards the outer peripheral surface of the annular member 21. The third hollow portion 23c is provided above the other ends of the first hollow portion 23a and the second hollow portion 23b. The fourth hollow portion 23d is provided over an end portion of the first hollow portion 23a and the second hollow portion 23b and is open to the outer peripheral surface of the annular member 21 throughout a longitudinal direction of the latter. Thus, the first hollow portion 23a to the fourth hollow portion 23d form, for example, an approximately square ring shape and are continued.
    The protruding fastening portion 25 protrudes vertically from the bottom of each recess 23. For this reason, the entire root portion of the protruding fastening portion 25 is located on a lower side from the upper surface 21a of the recess. annular member 21, and the root portion is surrounded by the first hollow portion 23a at the fourth hollow portion 23d which are continued in a ring shape, as described.
    The respective protruding fastening portions 25 are approximately square in shape when viewed from a plane as illustrated in FIG. 3, and have an interior space 26 open towards the upper end. The protruding fastening portions 25 are provided so that one side constituting a long side thereof is perpendicular to the radial direction of the annular member 21. Two corners on one side near the open end of a receiving groove 32 of the protruding fastening portions 25, described later, in other words, two corners of the protruding fastening portions 25 near the outer periphery of the annular member 21 are respectively used as the contact portion 25a ( see Fig. 3).
    Referring to FIG. 4, the first hollow portion 23a to the third hollow portion 23c are recessed and formed into a semi-circular shape, and, referring to FIG. 5, the fourth hollow portion 23d is recessed and formed to form a 1/4 arc shape. For this reason, the lateral surface of the root portion of the protruding fastening portion 25 and the recess 23 are continued without forming an angle between the two, with the protruding fastening portion 25 having a gradually greater thickness toward the bottom. from the hollow 23.
    Referring to FIG. 3 and 5, the protruding fastening portion 25 has for example two flanges 27 at a lateral surface farthest from the outer periphery of the annular element 21. The flanges 27 are constituted by convex portions having an arc shape when we look at them from a plane. The strands 27 extend parallel to the direction of extension of a central axis (not shown) of the projection protruding portion 25. Referring to FIG. 5, the upper ends of the flanges 27 fall slightly from (from) the upper end of the protruding fastening portion 25, and the lower ends of the flanges 27 extend to the root portion of the protruding portion of fixing 25.
    Referring to FIG. 1, the annular member 21 is attached to the movement 11 so that the hook portion 29 is hooked to a lower surface 13 of the annular convex portion of the movement 11, and the engagement groove 22 engages the surface upper part of the gripping portion 12. By the aforementioned fixing, the hollow 23 separated by 180 degrees is located in a direction of 12 hours to 6 hours, as described in FIG. 2, and the upper surface 21a of the annular element 21, with the exception of the respective protruding fastening portions 25, is located to be slightly higher than the upper surface of the solar cell 15 (see Fig. 1 ). In addition, the positioning of the pair of recesses 23 is not limited to the direction from 12 o'clock to 6 o'clock, but it is also possible to position the pair of recesses 23 in a direction from 9 o'clock to 3 o'clock, or in d 'other directions.
    The dial 31 is molded in the form of a thin plate by a translucent material such as a transparent acrylic resin or a polycarbonate resin and a synthetic resin harder than a synthetic resin material that comes to mold the element. 21. The dial 31 has an approximately circular shape and has a diameter which is slightly smaller than the outside diameter of the annular element 21. In the dial 31, although not shown, displays such as graduation, number and pattern are provided. .
    The dial 31 has a plurality of receiving grooves 32 in the peripheral portion. The receiving grooves 32 of the protruding fastening portions 25 are formed to notch the dial 31 from the peripheral surface thereof, and are open to the peripheral surface 31a of the dial 31. The end which is open will be called "open end" in the sequel. The receiving grooves 32 of the respective protruding fastening portions 25 bear the same numerals as those of the protruding fastening portions 25, and are provided corresponding to the positioning of the protruding fastening portions 25. Thus, with reference to FIG. 6, two grooves for receiving the projecting protruding portions 32 are provided to be separated in the circumferential direction of the dial 31 by 180 degrees.
    Both sides of the receiving grooves 32 of the protruding fastening portions 25 in a width direction are subdivided by a holding portion 33, as illustrated in FIG. 3. The holding portion 33 is resiliently deformable. A width of the receiving groove of the protruding fastening portions 39, i.e. a distance between the holding portions 33, is formed to be narrowed by an open end end of the receiving groove 32 protruding fastening portions 25, in other words, the peripheral surface 31a of the dial 31. For this reason, in one case of the first embodiment, the holding portions 33 are inclined so that the retaining portions 33 approach to each other by the peripheral surface side 31a of the dial 31. In addition, the inclination may be provided in only one holding portion 33. The distance between the tip portions and the holding portions 33 subdivided in the receiving groove 32 of the protruding fastening portions 25, in other words, a width of the open end portion, which is a minimum width of the receiving groove 32 of the protuberance portions 25 is slightly narrower than a separate distance between two contact portions 25a of the protruding fixing portion 25.
    The dial 31 is fixed to the annular element 21 to cover the solar cell 15. The fixing can be done by pressing the dial 31 down from the upper part of the annular element 21 in a positioning state of the protruding fastening portion 25 and the receiving groove 32 of the protruding fastening portions 25 of the dial 31 relative to the annular member 21 which is fixed on the movement 11.
    Therefore, while the holding portion 33 causes deflection deformation (curvature deformation) mainly in the thickness direction of the dial 31, the receiving groove 32 of the protruding fastening portions 25 is backed by the protruding fixing portion 25. That is, since the projection protruding portion 25 is relatively lightly pressed to the receiving groove 32 of the protruding fastening portions 25, the holding portions 33 come into intimate contact with the contact portion 25a of the protruding fastening portion 25, and the holding portion 33 interposes the protruding fastening portion 25 therebetween in a direction perpendicular to the radial direction of the annular member 21, as illustrated in FIG. 3 or similar. With this, the flanges 27 come into contact with the groove bottom surface 32a of the receiving groove 32 of the protruding fastening portions 25.
    While the state is maintained, the rear surface of the dial 31 comes into contact with the upper surface 21a of the annular element 21, whereby it avoids the action of pressing. Therefore, the respective protruding fastening portions 25 can be accommodated in the receiving grooves 32 of the respective protruding fastening portions 25 respectively corresponding thereto, and the dial 31 is attached to the annular member 21, to cover the solar cell 15.
    In this case, the contact portions 25a, against which the holding portions 33 bear, are provided in the protruding fastening portions 25 near the outer peripheral surface side of the annular element 21, and thus, a length from the root of the holding portion 33 to the location near the contact portion 25a is long. In addition, the holding portions 33 are inclined to approach one another by the tip sides thereof so that the width of the receiving groove 32 of the protruding fastening portions 25 gradually narrows toward the open end of the groove. Thus, it is possible to extend the lengths from the bases of the holding portions 33 to the contact portions 25a, in comparison with the configuration in which the width of the receiving groove 32 of the protruding fastening portions 25 is not changed.
    Therefore, during the fixing operation of the dial 31 mentioned above, the dial can be fixed to the annular element 21 mainly by an easy elastic deformation of the holding portions 33 in the thickness direction of the dial 31, and at this time, the protruding fastener portion 25 is not unduly deformed using the root portion thereof as a support point.
    In addition, since the projection protruding portion 25 has an interior space 26 open towards the upper end thereof, when the dial 31 is fixed, in a case where a large force is applied to the protruding portion 25, the projection protruding portion 25 may be slightly curved to reduce the diameter. For this reason, it is possible to more easily perform the work of fixing the dial 31 to the annular element 21, by not causing the projection protruding part 25 to bend from the bases thereof.
    In addition, the root portion of the protruding fastener portion 25 is formed to be thicker than the upper side portion farther than that, but the root portion is located at the bottom side from the upper surface 21a of the annular element 21. For this reason, in the fixing of the dial 31 mentioned above, the root portion of the protruding fastening portion 25 does not interfere with (does not interfere) the establishment contact of the rear surface of the dial 31 with the upper surface 21a of the annular element 21.
    Referring to FIGS. 3, 6 or the like, the dial 31 has a plurality of clearance grooves 34 open to the peripheral surface thereof. The holding portion 33 is located between the clearance groove 34 and the receiving groove 32 of the projection protruding portions 25. The clearance grooves 34 are formed to notch the peripheral portion of the dial 31, for example V-shaped The depth thereof, for example, is approximately the same as the depth of the receiving groove 25 of the protruding fastening portions 25. The root portion of the holding portion 33 is located between the inner corner of the groove for receiving 32 protruding fastening portions 25 and the inner portion of the clearance groove 34, and the holding portion 33 can be elastically deformed in a direction narrowing the width of the clearance groove 34 using the root portion 34 as a point of support.
    For this reason, when the dial 31 is fixed, the holding portion 33 can also be elastically deformed while escaping towards the side of the clearance groove 34, and the holding portion 33 is more easily deformed so that elastic. As a result, it is possible to more easily perform the work of fixing the dial 31 to the annular element 21, by eliminating the deformation of the protruding fixing portion 25.
    As the attachment mentioned above, the dial 31 is maintained so that it does not clap.
    That is to say, since the holding portion 33 of the dial 31 comes into intimate contact elastically with the protruding fastening portion 25 of the annular element 21, it is possible to maintain the dial 31 so that it does not clap in the circumferential direction thereof. In addition, since the width of the receiving groove of the protruding fastening portions 32 is gradually narrowed towards the open end of the groove, even if the dial 31 attached to the annular member 21 attempts to be moved in the direction radial connecting the receiving groove 32 protruding fastening portions 25, in the protruding fastening portion 25 located on the opposite side of the direction of movement and the receiving groove 32 the protruding fastening portions 25 with it housed therein the protruding fixing portion 25 functions as a stop, whereby the intimate contact between the protruding fastening portion 25 and the holding portions 33 interposed therebetween is reinforced. With this, since the flange 27 of the protruding fastening portion 25 comes into contact with the groove bottom surface 32a of the receiving groove 32 of the protruding fastening portions 25, even if the dial 31 attached to the annular member 21 tries to move in the radial direction connecting the receiving groove 32 of the protruding fastening portions 25, the protruding fastening portion 25 may be omitted as a stop. Thus, it is possible to maintain the dial 31 so that the receiving groove 32 of the protruding fastening portions 25 does not clap in the radial direction.
    In addition, in the holding state, with reference to FIG. 3, between the inclined holding portion and the side surface of the projection protruding portion 25 facing thereto, a slot is formed gradually spreading to the groove bottom surface 32a of the receiving groove 32 of the protruding portions. 25 starting from the point of contact between the tip portion of the holding portion 33 and the contact portion 25a.
    As described above, the holding portion 33 of the dial 31 is long, and the clearance groove 34 provided in the dial 31 to interpose the holding portion between the latter and the receiving groove 32 of the protruding fixing parts 25, the elastic deformation is easier. For this reason, an excessive reaction force is suppressed sufficient to deform the dial 31 fixed to the annular element 21 by the holding portion 33 with the protruding fastening portion 25 between the latter, and the force is absorbed by the elastic deformation. of the holding portion 33 to narrow the clearance groove 34. Thus, it is possible to prevent a disadvantage of the case where the translucent dial 31 enters a blown state using the receiving groove 32 of the protruding fastening portions 25 as a support point, that is to say, a disadvantage in that the light reflections in each part of the dial 31 are different from each other, the clammed state of the dial 31 being easily visible, and the appearance of the wristwatch 1 is impaired.
    In addition, as described above, since the projection protruding portion 25 has the stop function, it is possible to reduce the force by which the holding portion 33 comes into intimate contact with the contact portion 25a of the projection protruding portion 25. Therefore, the elastic deformation of the holding portion 33 when fixing the dial 31 to the annular member 21 becomes easier, and as a result it is possible to perform more easily the work of fixing the dial 31.
    The dial 31 fixed in this way faces the rear surface of the cover glass 7, as shown in FIG. 1, and the peripheral portion of the dial 31 is covered by the flange 4b. Since the dial 31 is transparent, the natural light or the artificial light transmitted through the cover glass 7 and the dial 31 comes to enter the solar cell 15, and with this, the solar cell 15 is subjected to the photoelectric conversion. to generate electricity. Thus, the wristwatch 1 accumulates the electrical energy generated in this manner in an accumulator or a capacitor, and can cause the movement 11 by the electrical energy.
    In addition, the peripheral portion of the receiving groove 32 of the protruding fastening portions 25 of the dial 31 fixed to the annular element 21 comes into contact with the upper surface 21a of the annular element 21 and covers the recess 23. but, as shown in FIG. 4, the hollow 23 is open towards the outer peripheral surface of the annular element 21. For this reason, when the fixing of the dial 31 is bad and the rearrangement of the dial 31 is performed, or during a holding action, the When the dial 31 of the annular element 21 is removed, it is possible to easily insert a tool (not shown) such as a clamp to remove the dial 31 from the outside of the annular element 21 towards the first hollow portion 23a of the recess 23 or both.
    Therefore, after the placement of the tool behind the dial 31, it is possible to remove the dial 31 engaged with the protruding fastening portion 25 of the annular element 21 by pulling it with the tool. In addition, the pulling action can be performed in a position near the protruding fastening portion 25. In addition, as mentioned above, since the inclined holding portion 33 has a large overall length and the clearance groove 34 is provided in the dial 31, the elastic deformation of the holding portion 33 is easy, similar to the action of fixing the dial 31 to the annular element 21, and thus, there is no need for excessive force during this action to shoot. Thus, the dial 31 can be easily removed.
    In addition, as mentioned above, since the protruding fastening portion 25 protrudes upwardly from the bottom of the recess 23 provided in the annular member 21, and the root portions of each protruding fastening portion 25 are located at the lower side from the upper surface 21a of the annular element 21, the total length of the protruding fastening portion 25 is large (high) as a function of the depth of the recess 23. Therefore, even when the protruding fastening portion 25 is curved by the use of the root portion as a support portion, the elastic deformation thereof is relatively easy, and there is no concern that a crack (a crack) is generated in the root portion of the protruding fastening portion caused by stress concentration at this time.
    In addition, the root portion of the protruding fastening portion 25 is formed to be gradually thicker towards the bottom of the recess 23, the bottom of the recess 23 and the peripheral surface of the root portion are continued without at an angle to each other, and an upper portion from the root portion of the protruding fastener portion 25 and the peripheral surface of the root portion are also continued without an angle being formed between the two. For this reason, since the stresses are hardly concentrated in the root portion, the desire to see a crack (crack) forming in the root portion of the protruding fastening portion 25 by an external (external) force such as that a vibration applied to the wristwatch 1, can be reduced, and it is possible to reliably maintain a predetermined fixing state of the dial 31 to the annular element 21.
