Field of the invention
The invention relates to a watch, such as a wristwatch, in which a power supply cell for an electricity generation or a light emission is provided in a module displaying the time or similar, and the panel is covered with a display board. In particular, the invention relates to a watch in which a fixing configuration of the display plate is improved.
State of the art
As the state of the art, it is known a watch in which an energy supply cell consisting for example of a solar power supply cell or electroluminescence and a translucent display plate covering them are arranged on the display module (see for example 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 display module, and the auxiliary ring is attached to the display 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 display 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, a diameter of the cylindrical protrusion is not changed from a root portion thereof to a point thereof, and the holding of the display plate to the auxiliary ring only depends on an engaging force which acts from the cylindrical protrusion to an edge of the notch in a horizontal direction (a lateral direction).
By such an engagement force, a deformation based on the plurality of notches is easily generated in the display plate having a relatively low resistance, whereby a distortion is generated in the display plate. Since the appearance of distortion degrades the quality of the watch, we want an improvement.
In addition, an assembly comprising an auxiliary ring and a display plate attached thereto, as mentioned above, is moved to the incorporation until it is incorporated into a watch casing after the integration of the assembly, and thus, the assembly receives the vibration or the like at this time. For this reason, in the configuration of the state of the art mentioned above, in which the display plate is held only by the force of engagement with the cylindrical protrusion, the display plate is moved up and floats due to vibration or the like, such a situation progressing further and the display plate can deviate.
As mentioned above, in the state-of-the-art watch, there is a problem that it is very likely that the display plate is fixed in a deformed manner, and the plate of display floats or deviates with respect to the annular member until the auxiliary ring and the display plate attached thereto are incorporated in the outer watch assembly.

Movement 11 has a circular shape when viewed from a plane. The movement 11 is incorporated in the cladding 2 of the watch 1 with an annular element 21, a display dial 31 or the like described later.
The movement 11 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 portion of the end of a ring-shaped convex portion continued in a circumferential direction of movement 11. Referring to FIG. 1, the engagement portion 12 is slightly deepened in the back side (the lower side) of the movement 11 relative to the upper surface 11a of the movement 11.
The solar cell 15 is a power supply cell in which a solar cell (not shown) 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 a bonding element it is possible to use a double adhesive tape very suitably. face of which both sides 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 a shoulder portion 21b (see Fig. 5) descending from the upper surface 21a. The shoulder 21b is formed continuously in the ring-shaped circumferential direction. The annular member 21 has hook portions 28 (only one of which is shown in Fig. 1) in a plurality of locations on the back surface, and has recesses 23 in the shoulder portion 21b and convex portions. engaging the same number as those in a plurality of locations.
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. As illustrated in figs. 4 to 6, the respective depressions 23 are respectively open from the upper surface of the shoulder portion 21b to the upper surface 21a of the annular member 21 and the outer peripheral surface of the annular member 21.
The male fastening portion 25 is surrounded by the recess 23 in a root portion 25a thereof and protrudes upwardly. For this reason, most of the root portion 25a of the male attachment portion 25 is located at the lower side from the upper surface of the shoulder portion 21b less than (lower than) the upper surface 21a of the annular member 21, and the root portion 25a is formed lengthwise as a function of the depth of the recess 23. The male attachment portion 25 is resiliently deformable in a radial direction of the annular member 21 and the dial 31 based on the lower end of the root portion 25a, i.e. the root.
In addition, as illustrated in FIG. 4 or similar, the recess 23 is also open to the outer peripheral surface of the annular member 21 on both sides of the root portion 25a of the male attachment portion 25. When the display dial 31 is removed, Later, from the annular element 21, a pair of open hollow portions may be used as a part in which a tool, such as a clamp, intended to be inserted towards the rear side of the dial 31, is inserted.
The male fastening portion 25 has a retaining member 25b. The retainer 25b is integrally and seamlessly arranged above the root portion 25a and constitutes an upper portion of the male attachment portion 25. A height of the upper end surface of the 25b is greater than (greater than) that of the upper surface 21a of the annular element 21. In addition, a thickness of the retaining element 25b in the radial direction of the annular element 21 is constituted in order to be thicker than those of other parts of the convex engaging portion 25 except for the retainer 25b (see Fig. 5). In addition, the reference sign 21c in FIGS. 4 and 6 indicates a die or die cut hole for molding the retaining member 25b integral with the annular element 21.
As illustrated in FIGS. 4 and 6, the retaining member 25b has inclined retaining surfaces 26 on both sides in the width direction thereof. The inclined retaining surfaces 26 are inclined so that the distance between them is gradually increased, i.e. the width of the pressing portion 25b faces upwardly.
As illustrated in FIGS. 3 to 6, a contact protrusion 27 protruding from the outer peripheral surface of the annular member 21 is integrally formed in the upper portion of the convex engaging portion 25. The contact protrusion 27 is formed, for example, by a bulge which extends vertically, but may be constituted by a single projection or bulge which extends in the circumferential direction of the annular element 21.
As illustrated in the. Fig. 1, the annular member 21 is attached to the movement 11 so that a hook portion 28 is attached to a lower surface 13 of the annular convex portion of the movement 11, and the engagement groove 22 is engaged with the upper surface of the engagement portion 12. By the aforementioned attachment, the hollow 23 and the male securing portion 180 separated by 180 degrees are arranged in a 12 o'clock-6 o'clock direction, as described in FIG. fig. 2, and the upper surface 21a of the annular member 21, except for the respective male attachment portions, is located to be slightly greater than (higher than) the upper surface of the solar cell 15 (see FIG. 1). In addition, the positioning of the pair of male fastening portions 25 is not limited to the 12 o'clock-6 o'clock direction, such as the recess 23, but it is also possible to position the pair of male fastening portions 25 in a direction from 9 am to 3 am or in other directions.
The display dial 31 is molded in the form of a thin plate by a translucent synthetic resin such as a transparent acrylic resin or a polycarbonate resin and capable of being elastically deformed. The dial 31 has an approximately circular shape and has a diameter which is slightly smaller than the outer diameter of the annular member 21. As illustrated in FIGS. 4 and 5, the thickness of the dial 31 is greater than a height dimension of the retaining element 25b in the vertical direction of the annular element 21. On the dial 31, although not shown, displays such as graduations, numbers and patterns are provided.
As illustrated in FIGS. 6, 7 or the like, the display dial 31 has a plurality of retainer receiving grooves 32 and female attachment portions 33 in the peripheral portion thereof. The respective retainer receiving grooves 32 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 element receiving grooves respective retainers 32 bear the same number as that of the male fastening portion 25, and are provided to correspond to the positioning of the male fastening portion 25. Thus, with reference to FIG. 7, two retaining member receiving grooves 32 are provided to be 180 degrees apart in the circumferential direction of the display dial 31.
The female attachment portion 33 of the display dial 31 has an inclined receiving surface 33a that delimits a portion of the retention member receiving groove 32. As shown in FIG. 6, the retaining member receiving groove 32 is formed to be gradually enlarged, the inclined receiving surface 33a being oriented in the width direction thereof and directed upwardly.
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 downwards from the upper part of the annular element 21 in a positioning state of the male fastening portion 25 and the retainer receiving groove 32 of the dial 31 relative to the annular member 21 which is attached to the movement 11, and installing the element receiving groove retainer 32 to the retainer 25b of the male fastening portion 25. Alternatively, the fastening may be effected by tilting the dial 31, by installing a retainer receiving portion 32 of the dial 31 to the retainer 25b of a male fastener portion 25, and then deflect the dial 31, inclining the dial 31 toward the other male fastener portion 25, and installing the other retainer receiving groove 32 from the dial 31 to the el holding member 25b of the other male fastening portion 25.
When the dial 31 is attached to the annular member 21, the male fastening portion 25 may be elastically deformed based on the root of the male fastening portion 25 in a direction in which the retainer 25b deviates from the retainer receiving groove 32. Accordingly, a work of positioning the retainer receiving groove 32 in a position where the female attachment portion 33 is squeezed by the retainer 25b from above is facilitated, and it is possible to further improve the workability of fixing the hour plate 31.
In addition, since the root portion 25a of the male fastening portion 25 is surrounded by the recess 23, the male fastening portion 25 is provided for a long time, and the elastic deformation thereof is easier. For this reason, it is possible to prevent the generation of a crack in the root due to the elastic deformation of the male fastening portion 25.
In the state where the fixing of the dial 31 on the annular element 21 is completed, as illustrated in FIG. 5, most of the retaining member 25b is housed in the retention member receiving groove 32. In this manner, the retaining members 25b of the male fastening portion 25 are housed in the receiving grooves of retaining element 32 respectively formed in the peripheral portion of the dial 31, whereby it is possible to position the dial 31 in the circumferential direction of the annular element 21.
With this, as illustrated in FIG. 4, the lower surface of the female attachment portion 33 of the dial 31 attached to the annular member 21 engages the upper surface 21a of the annular member 21, and the inclined receiving surfaces 33a of the female attachment portion. 33 engage respectively with the inclined retaining surfaces 26 of the retaining member 25b from above.
That is, in the state where the retaining member 25b of the male fastening portion 25 having the pair of inclined retaining surfaces 26 contacting the tapered receiving surface 33a comes into play. between the pair of female attachment portions 33 having the receiving inclined surface 33a oriented in the width direction of the retainer receiving groove 32 in top wedge shape, the pair of fastening portions females 33 are vertically interposed between the retaining member 25b of the male attachment portion 25 and the upper surface 21 of the annular member 21. In other words, in the state where the pair of female attachment portions 33 formed in tapered shape come between the retaining element 25b and the upper surface 21a of the annular element 21 in a wedge shape from a transverse direction in order to interpose the fixing part In the width direction thereof, the pair of female fastening portions 33 is interposed vertically between the retaining member 25b of the male fastening portion 25 and the upper surface 21a of the member. In addition, the upper end of the retaining element 25b comes down from the upper surface (the surface) of the dial 31.
As mentioned above, since the reception is interposed vertically between the retaining element 25b which has just entered between the pair of female fastening parts 33 in the wedge shape and the upper surface 21a of the element annular 21, the dial 31 can be held so as not to be moved vertically. In addition, it is possible to hold the dial 31 so as not to be displaced in the circumferential direction by using the retainer 25b of the male fastening portion 25 as a stop.
Furthermore, since the male fastening portion 25 and the female fastening portion 33 support the floating abutment and the rotational abutment of the hour plate 31, the configuration is simple compared to the configuration where the parts are provided separately.
In addition, it is possible to prevent the dial 31 from moving towards the upper side, floats or deviates with respect to the annular element 21, caused by the vibration applied to the annular element 21 mounted with the dial. 31, until the annular element 21 is incorporated in the clothing 2, by the retaining element 25b of the male fastening portion 25 with the peripheral portion of the dial 31 interposed vertically between the retaining element 25b and the upper surface 21a of the annular member 21. In addition, even if the dial 31 attached to the annular member 21 attempts to be moved in a radial direction connecting the retainer receiving groove 32, the motion can be prevented by using the male fastening portion 25 as a stop.
As mentioned above, since the retaining member 25b of the male fastening portion 25 is brought into contact with the female fastening portion 33 of the dial 31 from above, in order to perform the floating abutment of the 31 to the annular element 21, excessive stress is hardly generated around the retaining member receiving groove 32 by the male fastening portion 25. As a result, it is possible to prevent the dial 31 is fixed to the annular element 21 in a deformed state so as to wobble from the retention element receiving groove 32. Thus, it is possible to avoid the disadvantage when the dial 31 enters a corrugated state. That is to say, the dial 31 can be fixed so as to avoid the disadvantage that the light reflections differ from each other in each part of the dial 31, that the wavy state of the dial is easily visible. , and that the appearance of the watch 1 is hindered.
In addition, the assembly comprising the movement 11, the solar cell 15 connected thereto, the annular element 21 fixed to the movement 11, the dial 31 fixed to the annular element 21 or the like is incorporated in the middle 4 to which the bottom 5 is not fixed through an opening closed by the bottom 5. In this case, as shown in FIG. 1, since the contact protrusion 27 protruding towards the male fastening portion 25 comes into contact with the inner peripheral surface of the caseband 4, the assembly is slightly pressed and is incorporated in the caseband 4.
In the assembly mentioned above, since the upper end of the retaining element 25b of the male fastening portion 25 is located to be less than (lower than) the upper surface so as not to do protruding from the upper surface of the peripheral portion of the dial 31, the upper surface of the peripheral portion of the dial 31 comes into contact with the lower surface of the gap 9 by using the spacing 9 per degree, whereby the integration of the assembly in the caseband 4 is completed. For this reason, a slot caused by the retaining member 25b is not formed between the gap 9 and the upper peripheral portion surface of the dial 31 covered from above. Thus, it is possible to prevent a deterioration of the appearance of the wristwatch 1.
In addition, by the integration of the assembly, the contact protrusion 27 protruding from the male attachment portion 25 mentioned above, comes into intimate contact with the inner peripheral surface of the body 4, and the element 25b of the male fastening portion 25 is pushed toward the inner side of the retention member receiving groove 32. Accordingly, the contact between the deformable retainer 25b and the female fastening portion 33 of the dial 31 is reinforced, and it is possible to hold the assembly in the radial direction of the cladding 2 to not clack.
The dial 31 fixed in this way faces the rear surface of the window 7, as shown in FIG. 1. Since the dial 31 is translucent, the natural light or the artificial light transmitted through the lens 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 for 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.
Figs. 7 to 14 show a second embodiment of the present invention. A wristwatch according to the second embodiment is the same as that of the first embodiment having a configuration not shown in FIGS. 7 and 8 except for the configuration described below. For this reason, the same configurations as those of the first embodiment bear the same reference signs as the first embodiment, and their description will be omitted.
In the second embodiment, as shown in FIGS. 10, 11 and 13, the retaining member 25b of the male attachment portion 25 has side surfaces 29 inclined so as to be close to each other towards the tip side, and is formed in tapered form. That is, the downward retainer 25b has a narrowed width at the tip. In addition, as illustrated in FIGS. 12 and 13, the male fastening portion 25 has a groove portion 25c which is continuously formed on the lower side of the retainer 25b.
As shown in FIG. 9, the retaining member receiving grooves 32 provided at a plurality of locations of the dial 31, for example in a position separated by 180 degrees in the circumferential direction, face each other, as illustrated in FIG. figs. 13 and 14. Preferably, the retaining member receiving grooves 32 are delimited by the parallel groove side surface 32a and the inclined receiving surface 33a constituting the bottom surface of the retaining member receiving groove 32, and are open. on the upper surface and the peripheral surface of the dial 31. The female attachment portion 33 has the inclined receiving surface 33a, and the inclined receiving surface 33a is downwardly inclined and facing the opening end of the dial. the retaining element receiving groove 32.
As shown in FIGS. 7 and 12, the tip portion of the retainer 25b housed in the retainer receiving groove 32 engages the bottom surface of the retainer receiving groove 32; that is, the inclined receiving surface 33a of the female attachment portion 33, from above. Therefore, since the female attachment portion 33 is vertically interposed between the retaining member 25b and the upper surface 21a of the annular member 21, it is possible to hold the dial 31 so as not to be moved vertically. With this, a thin end portion of the female fastening portion 33 pressed from the top engages the groove portion 25c of the male fastening portion 25, and is supported by the root portion 25a of the fastening portion. male 25 from the bottom.
In addition, as illustrated in FIG. 10, the slope side surfaces 29 of the retaining member 25b come into intimate contact with the wedges 31b respectively formed by the groove side surface 32a and the circumferential surface of the dial 31. Therefore, it is possible to hold the dial 31 so as not to be displaced in the circumferential direction by using the retainer 25b of the male fastening portion 25 as a stop.
Thus, in the second embodiment, since the male attachment portion 25 and the female attachment portion 33 can also support the floating abutment and the rotational stop of the dial 31, the configuration is simple compared to the configuration in which the parts are provided separately.
[0074] Configurations and actions other than those described above are the same as those of the first embodiment. For this reason, in the second embodiment, for the same reason as described in the first embodiment in advance, the same action as the first embodiment is obtained, and the object of the present invention can be achieved. . That is, it is possible to provide a wristwatch 1 which can prevent the distorted attachment of the display plate and may prevent the dial 31 from floating or deflecting towards the annular member until what the dial 31 attached to the annular element 21 is incorporated in the casing 2 of the watch.
In addition, the present invention is not limited to the respective embodiment mentioned above. For example, it is possible to use a light emitting cell instead of the solar cell in the respective embodiments mentioned above. In the case of a light-emitting cell, for example, a cell made of a light-emitting element may be suitably used, and the light-emitting cell emits light by the electrical energy which is supplied from an accumulator or similar installed in a watch dressing. In this case, the light emitting cell emits light by the electrical conduction to it, the backlight of the display plate is generated by the light emitting cell, and thus the visibility of the time display (hour) or the like can be further improved. In addition, the present invention can also be applied to a pocket watch or the like besides the wristwatch.
