Description

The present invention relates to a wristwatch, a wristwatch piece, and a windshield for a wristwatch, and more specifically, it easily adds a bespoke decorativeness while significantly improving the decorative effect without impairing the visibility with respect to time. The present invention relates to a wrist watch, a wrist piece for a wrist watch, and a windshield for a wristwatch.

Traditionally, wristwatches have been widely used, and mechanical type, quartz type analog type, or digital type has been adopted.Recently, radio controlled clocks that can correct the time, satellite radio controlled clocks, solar clocks that can be charged by sunlight are used. Has been adopted.
Patent Document 1 discloses a mechanical wristwatch having an enhanced decorative effect without sacrificing visibility.

This wrist watch has a minute hand and a minute hand that are rotatable around a common predetermined position on the surface, and has a dial that displays the time according to the angular positional relationship between the minute hand and the minute hand, and a transparent windshield that covers the dial. , Covering the dial with a linear ridge descending from one apex towards the outer edge, with a draft shield having a plane extending between adjacent ridges, each plane radiating from the apex, the entire draft shield Visibility is secured. Since the reflection direction of light is different for each plane, even if the visibility deteriorates due to the reflection of light on one plane, the position of the needle can be confirmed on another plane. Moreover, the diversified light reflection enhances the decorative effect of the watch.

However, first, by devising the shape of the upper surface of the windshield, even if the decorative effect of the watch can be enhanced to some extent by utilizing the diversification of the reflection of light, the reflection of the reflection of light can be varied. As a result, the visibility with respect to the time is surely reduced.
More specifically, when the windshield is viewed from the front, all of the multiple planes are reflected, so there is no choice but to look at the windshield obliquely. Due to the relationship, the visibility of the time may not be secured.

Secondly, it is difficult to easily give a custom-made decorative property to a wristwatch.
More specifically, it is possible to adjust the degree of decorativeness by selecting the number of multiple planes provided on the top surface of the windshield and the inclination angle of the planes, but it is an option from the viewpoint of compatibility with visibility. In addition, it is difficult for the purchaser of the wristwatch to easily provide the decorativeness by order-making, for example, the purchaser of the wristwatch presents his/her initials and decorates on the spot.

On the other hand, Non-Patent Document 2 discloses a wrist watch in which brooch-like ornaments such as petals and animals are adhesively fixed to the surface of a windshield.
Such a wristwatch has an excellent decorative effect, but has the following problems.
First, the visibility of the time is poor and it is not practical.
More specifically, the brooch-like ornament covers more than half the area on the surface of the windshield, making it difficult to confirm the position of the long and short hands, and within the area of the dial not covered by the brooch-like ornament, Although a device provided with a small long and short hand is disclosed, it goes without saying that it lacks visibility.
Secondly, there is a great risk that ornaments will be removed from the wristwatch.
More specifically, since the brooch-like ornament is attached in a form protruding from the surface of the windshield and has a complicated and elaborate shape, it is possible that the brooch-like ornament may be caught on something and fall off the wristwatch. In this sense, the wristwatch of Non-Patent Document 2 is a figurine as a decorative craft and lacks practicality.
Since the windshield is usually transparent, the area visible through the windshield of the dial is the area where the minute hand and the minute hand rotate, even if a precious metal is placed on the dial that constitutes the dial. Therefore, it is difficult to secure an area for arranging the precious metal, and the dial is made of a metal or resin thin plate material, and it is difficult to fix the precious metal on the dial.

Patent Document 3 discloses a wristwatch in which a crystalline lens is provided at the center of the outer surface.
However, from the viewpoint of obtaining a so-called crystal power stone, the crystalline lens is provided at the position where it comes into contact with the skin, that is, the back surface of the wristwatch, and the aspect of the crystalline lens is determined from the viewpoint of ensuring a contact area as large as possible. However, the crystalline lens is not provided on the windshield side where the visibility of the watch becomes a problem.

A first embodiment of a wristwatch, a wristwatch top, and a wristwatch windshield according to the present invention will be described below in detail with reference to the drawings.

As shown in FIGS. 1 and 2, the wristwatch 10 includes a belt 48 and a wristwatch body 11, and the belt 48 is connected to the wristwatch body 11 via a lug 50. A buckle 52 is connected to the belt 48, and the buckle 52 connects one belt 48 and the other belt 48 so that the belt 48 fixes the wristwatch body 11 to the user's arm. That is, the length of the center line 56 from the buckle 52 to the hole of the belt 48 corresponds to the length around the wrist.

The wristwatch main body 11 is provided with a minute hand 12 and a minute hand 14 which are rotatable about a common predetermined position on the surface thereof, and a dial 16 and a dial 16 for displaying the time based on the angular positional relationship between the minute hand 12 and the minute hand 14. And a transparent windshield 20 having a recess 18, and the long hand 12 and the short hand 14 each have one end portion 22 which is an end portion on the side of the support shaft 58, which is provided at a center portion 24 of the dial 16. By rotating around the portion 24, the time is displayed by each of the other end portions 26 which are the end portions on the index 60 side.

More specifically, as shown in FIG. 3, the windshield 20 covering the dial 16 constitutes a space 17 between the surface of the dial 16 and the inner surface of the windshield 20, in which the long hand 12 and the short hand 14 are arranged. In addition, a movement 21 that is coupled to the dial 16 via an annular bezel 62 and that drives the long hand 12 and the short hand 14 to rotate is housed between the lower surface of the dial 16 and the back cover 19.
The bezel 62 has a circular shape and is arranged concentrically with the dial 16 so as to surround the periphery of the dial 16. The windshield 20 is fitted into the bezel 62. A crown 64 is attached to the bezel 62, and by operating the crown 64, a rotation operation around the support shaft 58 of the long hand 12 is possible.
The dial 16 has, for example, a circular contour, and the belt 48 is attached to the wristwatch body 11 such that the center of the circle overlaps the center line 56 of the belt 48, and particularly, along the center line 56 of the belt 48. The 12 o'clock direction and the 6 o'clock direction are defined.

The support shaft 58 is arranged in the central portion 24 of the dial 16, and the long hand 12 and the short hand 14 are fixed to the support shaft 58. Each of the long hand 12 and the short hand 14 linearly extends from the support shaft 58 toward the outer edge of the dial 16, and indexes 60 are radially fixed to the position near the outer peripheral edge of the dial 16 around the support shaft 58.
A movement 21 accommodated in the wristwatch body 11 behind the dial 16 is connected to the support shaft 58, and the movement of the movement 21 causes the long hand 12 and the short hand 14 to rotate about the support shaft 58.
For each of the long hand 12 and the short hand 14, even if the one end portion 22 is not visible, that is, the center portion 24 of the dial 16 is not visible through the windshield 20, the other end portion 26 is visible. For example, the time can be visually recognized, and in particular, the index 60 supports the reading of the time.

The dial 16 is formed of, for example, a plate material made of metal or resin. The windshield 20 is made of a resin or glass, is made of a transparent material, covers the long hand 12, the short hand 14 and the dial 16 to protect the long hand 12, the short hand 14 and the dial 16, and the long hand 12, the short hand 14 The index 60 can be visually recognized, and in this sense, the windshield 20 may be transparent with a color.

Next, the top 28 and the recess 18 in which the top 28 is embedded, which is a feature of the present invention, will be described.
As shown in FIGS. 4 and 5, the top 28 can be fitted into the recess 18, and the top 28 has an outer shape that does not impair the visibility of the time displayed by the long hand 12 and the short hand 14, A decorative upper surface portion 38 is formed inside the outer peripheral edge 30 corresponding to the peripheral edge of the opening of 18.
The windshield 20 and the top 28 are concentric circles centered on the central portion 24 of the dial 16, and the radius D1 of the top 28 is 1/5 or more and 2/3 or less of the radius D2 of the windshield 20. The radius is, for example, 3 mm to 7 mm in consideration of the size of the wristwatch main body worn on the wrist. If it is less than 1/5 of the radius of the windshield 20, it is sufficient for the visibility of the time, but the proportion of the top 28 to the windshield 20 is inferior in terms of decorativeness, and conversely, it is 2/3 of the radius of the windshield 20. If it exceeds, the decorativeness will be emphasized, but the visual recognition of time will be insufficient.
As a result, the long hand 12 and the short hand 14 are visible in the annular region 34 between the outer peripheral edge 30 of the top 28 and the peripheral edge 32 of the dial 16.
The thickness d (corresponding to the depth of the concave portion 18) of the top 28 may be determined from the viewpoint of easy processing of the concave portion 18 with respect to the windshield 20 and ensuring the strength of the windshield 20 made of glass. It is preferably 1 or less, for example, 1 mm to 3 mm. The lower surface of the top 28 does not need to be flat because it is not visible and the decorative elements are thinner than the decorative upper surface 38.

In this way, if the other end 26 of the long hand 12 and the short hand 14 is visible, it is sufficient to display the time without displaying the entire long hand 12 and the short hand 14, and one end of the long hand 12 and the short hand 14 is displayed. It is possible to utilize the periphery of the portion 22, that is, the periphery of the central portion of the windshield 20 for improving the decorative property.
In this case, it is possible to improve decorativeness to some extent by printing or etching a pattern, a pattern or the like on the upper surface 23 of the windshield 20 around the central portion of the windshield 20, but as will be described later. By fitting the top 28 made of a material different from that of the windshield 20 around the central portion of the windshield 20, and by printing or etching the outer shape and/or the decorative upper surface portion 38 or embedding the noble metal M, It is possible to produce a high-class decorative effect.

The top 28 has a solid shape complementary to the recess 18, and is made of metal, resin, or ceramic, and the noble metal M is embedded in the decorative upper surface portion 38.
More specifically, it is preferable to provide a groove portion in which the precious metal M can be embedded in the decorative upper surface portion 38 and fix the groove with an existing adhesive used for a jewelry ring. As a method of processing the groove in which the noble metal M can be embedded in the decorative upper surface portion 38 of the top 28, a physical means for processing the concave portion 18 in the upper surface 23 of the windshield 20 described later or laser processing may be used. Processing of the top 28 is easier than precision processing of the windshield 20.
Specific examples of metal include gold, silver, platinum, and titanium. Specific examples of the noble metal M include diamond, ruby, sapphire and the like. The top 28 may be formed in the hollow according to the outer shape thereof.
The material of the top 28 and the type of the noble metal M may be appropriately selected from the designability of the combination of their colors, luster, tint and the like.
In FIG. 4, the precious metal M is embedded in the central portion of the decorative upper surface portion 38 and is printed with TAROU HANAKO. In FIG. 5, the precious metal M1 is embedded in the central portion of the decorative upper surface portion 38 and A plurality of precious metals M2 are embedded around M1 at intervals in the circumferential direction.
On the other hand, the recess 18 is a groove 36 facing the upper surface 23 side of the windshield 20, and the top 28 can be fitted into the groove 36 from above. More specifically, the groove 36 is a column having a circular bottom surface, and may be configured to allow the top 28 to be tightly fitted. A known transparent adhesive used for fixing the windshield 20 to the dial 16 may be applied to the bottom surface and the side surface of the groove 36 to more securely fix the top 28 to the windshield 20.
The outer shape of the groove 36 is determined by the shape of the top 28 to be fitted, and does not have to be a columnar shape having a circular bottom surface, that is, a columnar body having a constant circular cross section, but for ease of fitting the top 28, for example, It is preferable that the shape is such that the diameter decreases toward the bottom surface, such as a truncated cone.

As a means for forming the concave portion 18 in the glass-like windshield 20, a physical means used when precisely processing a glass substrate having a thickness of 1 mm or less used as a display of a mobile terminal device such as a mobile phone or a PDA, or A laser processing method may be used.
As the physical means, conventionally known grinding methods such as dicing processing, wheel scribing processing, and water jet processing can be mentioned.

As a groove forming method by dicing, for example, a dicing device equipped with a donut disc-shaped blade rotatably is used, the windshield 20 is installed on a horizontally rotatable rotary table, and the windshield 20 is oriented in an appropriate direction. A method of stopping the rotary table and pressing the peripheral surface of the rotating blade against the upper surface 23 of the windshield 20 can be mentioned. Wheel scribing is a method that uses a rotating tool called a scribing wheel, which is widely used for cutting glass for liquid crystal, and the technology has already been established in the liquid crystal panel production line. By forming the scribe line, cracks are generated along the line perpendicular to the plate thickness direction. Water jet processing is a method of pressurizing water to a maximum of several hundred MPa, spraying it from a small diameter nozzle with a diameter of 1 mm or less, and using high-speed, high-density, high-pressure water energy to process an object. The water pressurized by the high-pressure water generation pump reaches about 3 times the speed of sound, and a destructive water jet is created.Therefore, its applications are diverse, and in familiar places, roof materials of automobiles, dashboards, It is used for cutting bumpers, cutting and dismantling concrete structures, and cutting aircraft using new materials.

A conventionally known method can be appropriately used as the laser processing method, and the method is not particularly limited. In the laser processing method, the recess 18 can be formed by scanning the planned recess position while adjusting the laser output. Further, instead of this method, a machining mark is preliminarily formed on the extension line of the position where the concave portion 18 is to be formed by using a blade or the like, and this machining mark is used as an initial starting point of the concave portion forming position by the laser. It is also possible to form the recess 18 in which the crack of the initial starting point is propagated by performing the cooling treatment along the position where the recess 18 is formed.

The windshield 20 has a flat upper surface 23, the maximum thickness t is about 3 mm to 6 mm, and the central portion is formed to have the maximum thickness. The groove portion 36 is provided in the central portion. .. Accordingly, when the groove portion 36 is processed in the windshield 20, the processing becomes easy.
The top surface 23 of the windshield 20 may not only be flat, but may be spherical or arcuate in cross section (see FIG. 3). Further, it may have a linear ridge line 31 that descends from one apex coinciding with the central portion 24 of the dial 16 toward the outer edge and has a flat surface that spreads between the adjacent ridge lines 31.
The decorative upper surface portion 38 of the top 28 is exposed from the upper surface 23 of the windshield 20 and is flush with the upper surface 23 of the windshield 20. Therefore, the precious metal M embedded in the decorative upper surface portion 38 is provided so as to project from the upper surface 23 of the windshield 20.

As shown in FIG. 6, as a modification, a peripheral groove 37 may be provided on the peripheral side surface 66 of the top 28, and the noble metal M may be embedded in the peripheral groove 37. In this case, the noble metal M embedded in the circumferential groove 37 is located in the middle of the windshield 20 in the thickness direction, but since the windshield 20 is transparent, it is above the windshield 20 when the wristwatch 10 is worn on the wrist. It is possible to visually recognize the precious metal M inside, and it is possible to produce a sense of luxury by that amount.
The noble metal M embedded in the decorative upper surface portion 38, that is, the noble metal M protruding from the upper surface 23 of the windshield 20 and the noble metal M embedded in the windshield 20 may be used together.

As shown in FIG. 7, as a modification, the top 28 has a brim 42, the decorative upper surface portion 38 is constituted by the upper surface 40 of the brim 42, and the upper surface portion 23 of the windshield 20 is fitted into the groove portion 36 from above. The step 44 may be formed. As a result, when the top 28 is tightly fitted in the groove 36, fitting can be facilitated and the design can be improved.
Further, by fixing the annular lower surface of the protruding flange portion of the brim 42 and the upper surface 23 of the windshield 20 with an adhesive, the top 28 can be more firmly fixed to the groove portion 36.
In this case, the outer peripheral edge of the brim 42 forming the step 44 may have a curved design (for example, a heart shape, a spade shape, a clover shape) to improve decorativeness. In contrast, the recess 18 may be a through hole penetrating in the thickness direction of the windshield 20 instead of the groove portion 36 having a bottom, and the top 28 is formed as a throughhole until the inner surface of the brim 42 abuts the upper surface 23 of the windshield 20. Just plug it in.

When the recess 18 provided in the windshield 20 is used as a through hole, it is more important to ensure the airtightness of the space 17 between the windshield 20 on which the dial is arranged and the dial 16 than in the case of the simple groove 36. In order to prevent the moisture in the outside air from entering the space 17 through the space 17, the inner surface of the windshield 20 is fogged and the visibility of the time is not hindered. A circumferential groove is provided on the circumferential side surface of the top 28, and a transparent packing ( (Not shown), a brim 42 at the upper end of the top 28, or a transparent adhesive is evenly applied between the inner peripheral surface of the through hole of the windshield 20 and the outer peripheral surface of the top 28. It is preferable to secure the airtightness by bonding the windshield 20 and the top 28.

As a further modification, as shown in FIG. 8, a plurality of precious metals M may be embedded, and a plurality of precious metals M may form a character, a figure, a symbol, or a combination thereof (LOVE in the drawing). For example, when a wristwatch purchaser presents his/her name, initials, birthday, wedding anniversary, etc., it can be displayed by a plurality of precious metals M to improve the design.

As shown in FIG. 9, as a further modified example, the top 28 may be formed in an outer shape (a clover shape in the drawing) of a character, a figure, a symbol, or a combination thereof. For example, the wristwatch purchaser can present his/her name, initials, birthday, wedding anniversary, and other dates, and display them on the panel 28 to improve the design.
As a further modification, as shown in FIG. 10, the top 28 may have a ring-shaped opening 46, and the groove 36 may be formed with a protrusion that can be fitted into the opening 46. A plurality of noble metals M may be arranged at intervals in the circumferential direction of the ring.

As shown in FIGS. 11 and 12, as a further modified example, an etching pattern may be formed on the decorative upper surface portion 38, and the precious metal M is embedded in the decorative upper surface portion 38 having the etching pattern formed thereon. May be In FIG. 11, a plurality of linear patterns parallel to each other, and in FIG. 12, a heart-shaped pattern is applied.
As described above, the decorative effect is remarkably improved by devising the outer shape of the top 28, the type of the noble metal M to be embedded in the decorative upper surface portion 38, the arrangement thereof in the case of a plurality, the pattern to be processed on the decorative upper surface portion 38, and the combination thereof. Can be improved.
As a further modified example, as shown in FIG. 13, the windshield 20 has a linear ridge line 31 that descends from one apex coinciding with the central portion 24 of the dial 16 toward the outer edge, and between the adjacent ridge lines 31. It is also possible to adopt one having a flat surface 67 that spreads with the above, and provide the above-mentioned top 28 around one vertex. According to the above, it is possible to further improve the decorative property by diversifying the light reflection. Since the light reflection direction is different for each plane 67, even if the visibility is deteriorated due to the light reflection on one plane, the position of the needle can be confirmed on the other plane.

The operation of the wrist watch, the wrist watch top 28, and the wrist watch windshield 20 having the above-described configurations will be described below, taking as an example a case where a watch purchaser gives a custom-made decorative property on the spot.
First, when a watch purchaser decides which watch to buy, he or she presents his/her name, initials, birthday, etc., in order to make a custom-made decoration. In this case, a plurality of pairs of pieces 28 having different outer shapes such as a heart shape, a spade shape, and a clover shape and a groove portion 36 processed according to the outer shape of the piece 28 are prepared. The windshield 20 may be selected.
As for the lineup of the top 28 and the windshield 20, as for the top 28, a material including transparency, opacity or transparency with color, the outer shape of the top 28, and a position where the precious metal M is embedded (the upper surface 23, the peripheral side surface 66, In the lower surface 25) and the windshield 20, it is preferable to select a groove type, a through-hole type, or a recessed upper surface 23 or a lower surface 25 as the recessed portion in which the top 28 is provided.
Based on the presented characters, symbols, and patterns, the decorative upper surface portion of the wristwatch piece 28 is etched by, for example, laser processing, and the etched wristpiece piece 28 is, for example, transparent in the groove portion 36 of the windshield 20. The windshield 20 is attached to the dial 16 by an interference fit using the adhesive of 1 to complete the wristwatch.
As described above, it is possible to easily perform a custom-made decorative property on the spot.
In this case, not only when purchasing a new wristwatch, but when making a custom-made decoration on an existing wristwatch owned by oneself, the existing windshield 20 is recessed (processed) by laser processing on the spot, for example. It is also possible to mount the top 28 with a through-hole, which is better than the above, and which is provided with the above-described custom-made decoration on the spot.
When characters, symbols and patterns are displayed by embedding the noble metal M in the decorative upper surface portion 38 or the peripheral side surface 66, it is difficult to make a customized one on the spot, but a heart shape, a spade. By preparing in advance a piece 28 for a wristwatch in which a precious metal M is embedded in a piece 28 of a shape or the like, it is possible to select a desired piece 28 for a wristwatch and embed it in the windshield 20 on the spot.
