JP, 2005-308702, A

  In the wristwatch described in Patent Document 1, a plane area is formed in the center of a circular windshield, and a multifaceted cut is made along the contour of the windshield around the plane area. The index must be placed inside the annular facet, as the dial is less visible at the facet. Therefore, the arrangement of the indexes and the length of the hands are reduced as compared with the size of the watch case. When you want to know the time, the visibility drops. Moreover, when light is incident on the windshield at a specific angle, the visibility of the entire plane area deteriorates due to the reflection of light. I cannot confirm the position of the needle.

  It is an object of the present invention to provide a wristwatch having an enhanced decorative effect without sacrificing visibility.

  According to the first aspect of the present invention, a wristwatch including a dial and a windshield that covers the dial and has a linear ridgeline that descends from one apex toward the outer edge and has a flat surface that extends between adjacent ridgelines. Will be provided.

  According to the second side surface, in addition to the structure of the first side surface, the apex is located on the extension line of the support shaft of the needle.

  According to the third aspect, in addition to the configuration of the first or second aspect, the windshield is projected on the dial in the 12 o'clock direction, the 3 o'clock direction, the 6 o'clock direction and the 9 o'clock direction. It is formed in a pyramid shape that overlaps the projection lines of the ridge lines.

  According to the fourth aspect, in addition to the configuration of the third aspect, the windshield has a square contour that diagonally overlaps the projection line.

  According to the first aspect, the individual planes radiate from the apex, and visibility is secured in the entire windshield. 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.

  According to the second aspect, the apex is located on the extension line of the support shaft of the needle. The visibility of the needle is maintained well because the ridge of the windshield does not cross the needle. Both the needles and the ridges extend radially from the spindle, creating a uniform design and enhancing the decorative effect of the windshield.

  According to the third side surface, the dial is divided into four equal parts according to the ridgeline at a position where it is easy to see. Therefore, the position of the needle can be easily specified. The time of day can be easily read. Moreover, the decorative effect is enhanced and at the same time the visibility of the needle is maintained in good condition.

  According to the fourth aspect, the 12 o'clock direction, the 3 o'clock direction, the 6 o'clock direction and the 9 o'clock direction can be easily specified based on the contour of the windshield. The position of the needle can be easily identified. The time of day can be easily read.

1 is a plan view schematically showing a wristwatch according to a first embodiment of the present invention. It is an expanded partial perspective view. It is a top view which shows schematically the wristwatch which concerns on 2nd Embodiment of this invention.

  An embodiment of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 schematically shows a wristwatch 11 according to the first embodiment. The wristwatch 11 includes a case 12 and belts 13a and 13b. The belts 13 a and 13 b are connected to the case 12 via a lug 14. A buckle 15 is connected to the belt 13a. The buckle 15 connects one belt 13a to the other belt 13b. The case 12 is fixed to the arm of the user by the belts 13a and 13b thus combined.

  A windshield 17 that covers the dial 16 is coupled to the case 12. The dial 16 has a square contour. The one diagonal line 16a of the square overlaps the center line 18 of the belts 13a and 13b. The 12 o'clock direction and the 6 o'clock direction are defined along the center line 18 of the belts 13a and 13b. The length of the center line 18 from the buckle 15 to the belt hole corresponds to the length around the wrist.

  A support shaft 19 is arranged at the center of the dial 16 (intersection of diagonal lines). A long hand 21a and a short hand 21b are fixed to the support shaft 19. The long hand 21a and the short hand 21b linearly extend from the support shaft 19 toward the outer edge of the dial 16. Indexes 22 are fixed to the dial 16 in a radial manner centering on the support shaft 19.

  The dial 16 is formed of, for example, a metal plate, a plastic plate, or another plate material. If the dial 16 is made of a transparent plate material, a so-called skeleton structure can be established. The windshield 17 is made of a transparent material such as glass or plastic. Thus, the windshield 17 covers the long hand 21a, the short hand 21b and the dial 16 to protect the long hand 21a, the short hand 21b and the dial 16, and allows the long hand 21a, the short hand 21b and the index 22 to be visually recognized. The index 22 assists in reading the time.

  A movement (not shown) is connected to the support shaft 19. The movement is housed in the case 12 behind the dial 16. Due to the movement of the movement, the long hand 21a and the short hand 21b rotate around the axis of the support shaft 19.

  The periphery of the dial 16 is surrounded by the bezel 23. The windshield 17 is fitted into the bezel 23. A crown 24 is attached to the bezel 23. In response to the operation of the crown 24, the rotation of the long hand 21b is caused around the axis of the support shaft 19.

  As shown in FIG. 2, the windshield 17 has linear ridges 27a to 27d that descend from one vertex 26 toward the outer edge. Between the adjacent ridge lines 27a to 27d, one flat surface 28a to 28d respectively extends. The apex 26 of the windshield 17 is located on the extension axis of the support shaft 19. The apex 26 may be arranged within the axis of the extension axis. Preferably, the apex 26 is desired to be located on the axis of the support shaft 19.

  The projection lines of the ridge lines 27a to 27d are overlapped in the 12 o'clock direction, the 3 o'clock direction, the 6 o'clock direction, and the 9 o'clock direction, respectively. Here, the projection line is obtained by projecting the ridgelines 27a to 27d on the dial 16 in parallel with the axis of the support shaft 19. The individual planes 28a to 28d partition the outer edge of the windshield 17 on the base of an isosceles triangle whose ridges 27a to 27d are equal sides. Thus, the windshield 17 is formed in a pyramid shape having the ridgelines 27a to 27d. Although the outlines of the dial 16 and the windshield 17 are formed in polygonal shapes such as squares, the corners of the outlines may be rounded with curved lines or chamfered with straight lines.

  As described above, the windshield 17 has the linear ridges 27a to 27d that descend from one vertex 26 toward the outer edge. The planes 28a to 28d extend between the adjacent ridgelines 27a to 27d. The individual planes 28a to 28d spread radially from the apex 26, and the visibility is ensured in the windshield 17 as a whole. The light reflection direction is different for each of the planes 28a to 28d, and even if the visibility is deteriorated according to the reflection of light on any one of the planes, the positions of the minute hand 21a and the minute hand 21b are confirmed on the other plane. You can Moreover, since the reflection of light is diversified, the decorative effect of the wristwatch 11 is enhanced.

  The apex 26 is located on the extension line of the support shaft 19 of the long hand 21a and the short hand 21b. Since the ridgelines 27a to 27d of the windshield 17 do not cross the long hand 21a and the short hand 21b, the visibility of the long hand 21a and the short hand 21b is maintained well. Since the long hand 21a, the short hand 21b and the ridge lines 27a to 27d all extend radially from the support shaft 19, uniformity of design is created and the decorative effect of the windshield is enhanced. Particularly, when the apex 26 is arranged on the axis of the support shaft 19, the windshield 17, the bezel 23 and the dial 16 are concentric around the support shaft 19, and the design of the wristwatch 11 is emphasized. it can.

  The windshield 17 is formed in a pyramid shape in which projection lines of the ridge lines 27a to 27d are overlapped in the 12 o'clock direction, the 3 o'clock direction, the 6 o'clock direction and the 9 o'clock direction. The dial 16 is divided into four equal parts according to the ridge lines 27a to 27d at a position that is easy to see. Therefore, the positions of the long hand 21a and the short hand 21b can be easily specified. The time of day can be easily read. Moreover, the decorative effect is enhanced and at the same time the visibility of the needle is maintained in good condition.

  The windshield 17 has a square outline in which diagonal lines overlap the projection lines of the ridge lines 27a to 27d. The 12 o'clock direction, the 3 o'clock direction, the 6 o'clock direction and the 9 o'clock direction can be easily specified based on the contour of the windshield 17. The positions of the long hand 21a and the short hand 21b can be easily specified. The time of day can be easily read.

  FIG. 3 schematically shows a wristwatch 31 according to the second embodiment. The dial 16 has a square contour having a diagonal line 32 that intersects the center line 18 at an angle of 45 degrees on the rotation axes of the long hand 21a and the short hand 21b. Therefore, the 12 o'clock direction and the 6 o'clock direction are defined parallel to the two sides of the square. The windshield 17 has linear ridges 27a to 27d overlapping the square diagonal line 32. The linear ridges 27a to 27d descend from the apex 26 on the rotation axis toward the outer edge. In this way, the windshield 17 is formed in a pyramid shape having four ridges 27a to 27d.
