JP 2002-318289 A

  However, in recent years, the preference for wristwatch decoration has been diversified, and there has been a demand for an unprecedented highly decorative dial. The present invention has been made to solve this problem, and an object of the present invention is to provide a wristwatch capable of improving the decorativeness.

  A wristwatch according to the present invention includes a cylindrical case, a cover glass that closes one end side in the axial direction of the case, a lid member that closes the other end portion in the axial direction of the case, and a pointer accommodated in the case A movement housed in the case and driving the pointer; a support plate disposed between the movement and the cover glass; and a decorative leather disposed on a surface of the support plate facing the cover glass. And the pointer is driven between the leather sheet and the cover glass.

  According to this configuration, since the leather sheet is affixed to the support plate, the surface corresponding to the dial of a conventional wristwatch can be configured with the leather sheet. Therefore, it is possible to provide a completely different appearance from the dial of a conventional wristwatch, and greatly improve the decorativeness of the wristwatch.

  In the wristwatch, a step portion extending along a circumferential direction may be formed on the inner wall surface of the case, and a peripheral portion of the leather sheet may be sandwiched between the support plate and the step portion.

  Thereby, since the peripheral part of the leather sheet is hidden inside the case, the entire surface of the region visible from the cover glass can be constituted by the leather sheet. Therefore, the entire surface corresponding to the conventional dial can be constituted by the leather sheet without precisely adjusting the size of the leather sheet.

  In the wristwatch, the leather sheet can be sandwiched between the step portion and the support plate by pressing the support plate from the lid member side by the movement.

  Thereby, since the peripheral part of the leather sheet is pressed between the stepped part and the support plate, the peripheral part of the leather sheet is caulked, and it is possible to prevent the change in thickness over time from occurring. it can. Therefore, it is possible to prevent the movement of the movement in the axial direction.

  In the wristwatch, the structure for pressing the support plate is not particularly limited.For example, the case further includes a cylindrical inner frame disposed between the lid member and the support plate in the case, The movement is supported inside the middle frame, and the lid member is attached to the case, whereby the middle frame is pressed by the lid member, and thereby the movement presses the support plate. can do.

  By providing such an inner frame, it is possible to prevent the displacement of the movement in the radial direction.

  In the wristwatch, the thickness of the leather sheet can be 0.1 to 1.0 mm. If the thickness of the leather sheet is such, it is difficult for the thickness to change depending on the environment or the like, so that the position of the movement in the axial direction can be prevented from changing.

  Various leathers such as cowhide, crocodile leather, snake leather, and lizard leather can be used as the leather sheet. Among these, since the leather has less surface irregularities, the use of cowhide makes it possible to make the thickness of the leather sheet constant in the surface direction. As a result, it is possible to prevent the movement of the movement in the axial direction.

  According to the wristwatch according to the present invention, the decorativeness can be improved.

It is a top view of the wristwatch concerning one embodiment of the present invention. It is the sectional view on the AA line of FIG. It is the BB sectional view taken on the line of FIG.

  Hereinafter, an embodiment of a wristwatch according to the present invention will be described with reference to the drawings. 1 is a plan view of a wristwatch according to the present embodiment, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB in FIG. Hereinafter, for convenience of explanation, the vertical direction in FIGS. 2 and 3 is referred to as “vertical”.

  As shown in FIGS. 1 to 3, the wristwatch includes a cylindrical case 1, and an annular projecting portion 11 projecting radially inward is formed on the upper portion of the inner wall surface of the case 1. ing. The protrusion 11 is formed in a rectangular cross section, and a step 12 is formed on the upper opening periphery of the case 1 between the upper surface of the protrusion 11 and the inner wall surface of the case 1. A circular cover glass 2 is fitted into the step portion 11. In addition, on the upper surface of the case 1, characters indicating time are covered on the peripheral portion of the cover glass 2, that is, the portion corresponding to the bezel. On the other hand, the lower opening of the case 1 is closed by a circular lid member 3. The lid member 3 includes a circular substrate portion 31 and a cylindrical male screw portion 32 that rises upward from the peripheral edge portion of the substrate portion 31. The male screw portion 32 is screwed into the female screw portion 13 formed on the inner wall surface of the lower opening of the case 1, thereby closing the lower opening of the case 1. Thus, an internal space is formed in the case 1 between the cover glass 2 and the lid member 3.

  A through hole 14 extending in the horizontal direction is formed on the side surface of the case 1 so that the outside of the case 1 communicates with the internal space. As will be described later, the winding stem 41 of the crown 4 is inserted into the through hole 14.

  In the internal space of the case 1, a leather sheet 5 and a support plate 6 are disposed below the protrusion 11. The leather sheet 5 is attached to the upper surface of the support plate 6 with an adhesive or the like, and these are formed in a circular shape having the same shape. Various leathers such as cowhide, crocodile leather, snake leather, and lizard leather can be used for the leather sheet 5, but it is preferable to use cowhide with less surface irregularities. The thickness is preferably 0.1 to 1.0 mm, more preferably 0.3 to 0.7 mm, and particularly preferably 0.4 to 0.6 mm.

  The peripheral portion of the leather sheet 5 is in contact with the step portion 15 formed by the lower surface of the protruding portion 11 and the inner wall surface of the case 1 from below. Thereby, between the cover glass 2 and the leather-made sheet | seat 5, the upper space where the pointer | guide 7 mentioned later is arrange | positioned is formed. A columnar movement 8 for driving the pointer 7 is disposed below the support plate 6. A rotation shaft 81 is provided at the center of the movement 8, and the rotation shaft 81 extends upward from a through hole formed in the center of the leather sheet 5 and the support plate 6 and protrudes into the above-described upper space. Yes. A needle 7 (long needle and short hand) extending radially outward is attached to the upper end portion of the rotating shaft 81. The movement 8 may be an electronic timepiece, that is, a quartz type timepiece, or a mechanical type timepiece.

  The movement 8 is formed smaller than the diameter of the internal space of the case 1, and is accommodated between the support plate 6 and the lid member 3 while being supported by the cylindrical inner frame 9. The middle frame 9 includes a cylindrical base 91 that surrounds the periphery of the movement 8, and a flange 92 that protrudes radially outward from the upper end of the base 91. More specifically, a plurality of protrusions 82 that protrude slightly outward in the radial direction are formed on the periphery of the upper end of the movement 8 at equal intervals. The protrusion 81 is pushed up from below by the upper end of the base 91 of the middle frame 9. As shown in FIG. 3, a recess into which the protrusion 82 is fitted can be formed at the upper end of the base 91. On the other hand, the lower end portion of the base portion 91 is in contact with the upper surface of the lid member 3, and the lid member 3 is screwed into the case 1, thereby pressing the base portion 91 of the middle frame 9 upward. 91 pushes the movement 8 upward. Therefore, the movement 8 presses the support plate 6 upward, whereby the peripheral portion of the leather sheet 5 is sandwiched between the support plate 6 and the step portion 15 on the lower surface of the protruding portion 11. Yes.

  Further, the radially outer end of the flange portion 92 of the middle frame 91 is in contact with the inner wall surface of the case 1, whereby the movement 8 is positioned at the center of the inner space. In the middle frame 91, a notch (not shown) is formed in the flange portion 92 and the base portion 91 at a position corresponding to the crown 4, and the winding stem 41 of the crown 4 is connected to the movement 8 through this notch. ing. Therefore, the pointer 7 can be adjusted by operating the crown 4.

  In the wristwatch, the inner frame 9, the movement 8, and the support plate 6 are pushed up by screwing the lid member 3 into the lower opening of the case 1. At this time, the pushing amount of the lid member 3 is normally determined by the type of the movement 8, but the peripheral edge portion of the leather sheet can be crimped by this pushing. Therefore, the pushing amount can be, for example, about 0.1 to 0.20 mm, particularly about 0.15 mm.

  According to the wristwatch configured as described above, since the leather sheet 5 is attached to the support plate 6, the surface corresponding to the dial of a conventional wristwatch can be configured by the leather sheet 5. Therefore, it is possible to create a completely different texture from the dial of a conventional wristwatch and greatly improve the decorativeness of the wristwatch.

  Conventionally, since a leather sheet was considered to have a large change with time, it was not used for a dial of a wristwatch. However, in the wristwatch according to the present embodiment, the thickness is small as described above. By using the leather sheet 5, it is possible to prevent the change with time from being easily generated. Further, in the wristwatch, the leather plate 5 is sandwiched between the step portion 15 and the support plate 6 by pressing the support plate 6 from below with the movement 8. Thereby, since the peripheral part of the leather sheet 5 is pressed between the step part 15 and the support plate 6, the peripheral part of the leather sheet 5 is caulked, and the change with time of the thickness occurs. Can be prevented. Therefore, it is possible to prevent the axial position of the movement 8 from changing. Therefore, it is possible to prevent the winding stem 41 of the crown 4 from deviating from the horizontal state.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning. For example, in the said embodiment, the magnitude | size of a support plate and a leather sheet is made the same, or it is not limited to this, A leather sheet may be small.

  Moreover, in the said embodiment, although the peripheral part of the leather sheet 5 is pinched | interposed between the support plate 6 and the step part 15, the peripheral part of the leather sheet 5 is hidden inside the case 1 by this. Therefore, the entire surface visible from the cover glass 2 can be constituted by the leather sheet 5. Therefore, the entire surface corresponding to the conventional dial can be formed of a leather sheet without precisely adjusting the size of the leather sheet 5. However, the outer diameter of the support plate 6 can be made larger than that of the leather sheet 5, and the outer diameter of the leather sheet 5 can be adjusted to be the same as the inner diameter of the protruding portion 11. In this way, the peripheral edge portion of the support plate 6 abuts on the step portion 15, so that the position of the movement 8 in the axial direction can be reliably positioned.

  The configuration of the leather sheet 5 is not particularly limited, and instead of providing characters on the bezel, characters can be printed on the surface of the leather sheet 5 or parts corresponding to the characters can be arranged.

  In the above-described embodiment, the middle frame 9, the movement 8, and the support plate 6 are pushed up by screwing the lid member 3 into the lower opening of the case 1. However, the configuration for pushing up the support plate 6 is not limited thereto. For example, the movement 8 can be directly pushed up by the lid member 3. Alternatively, the support plate 6 can be pushed up by a component other than the movement 8, and the middle frame 9 can be pushed up by screwing the lid member 3, and the support plate 6 can be pushed up by the middle frame 9.

  The wristwatch according to the above embodiment is an analog timepiece having hands, but a known liquid crystal display device can be arranged in the case 1 together with the movement 8 to perform digital display. For example, an opening is formed in the support plate 6 and the leather sheet 5, and the display unit of the liquid crystal display device is exposed from the opening. This display unit is a liquid crystal screen on which time and the like are digitally displayed. Thus, a wristwatch having both an analog display function and a digital display function can be provided.

  Further, the above-described parts, the shape of the part, etc. are not particularly limited. For example, in the above-described embodiment, a wrist watch having a circular shape in plan view has been described. However, the case, the cover glass, the leather sheet, the support plate, and the like can be polygonal in addition to rectangular. Further, the middle frame 9 is not necessarily required, and a member (a frame, a protrusion, etc.) for fixing the movement 8 to the lid member 3, the support plate 6, and the inner wall surface of the case 1 can be provided.
