Description

  The present invention relates to a wristwatch such as an electronic wristwatch, and more particularly to a wristwatch provided with a case body made of a synthetic resin.

  Conventionally, in a wristwatch, as described in Patent Document 1, a glass mounting portion on which a watch glass is mounted is provided on an upper portion of a synthetic resin case body, and a glass mounting portion is provided in the synthetic resin case body. The thing of the structure which embedded the metal reinforcement board for ensuring the intensity | strength of this corresponding to a glass mounting part is known.

Japanese Utility Model Publication No. 02-16306

  However, in such a conventional wristwatch, even if the strength of the glass mounting portion of the case main body can be secured by the metal reinforcing plate, the strength of the band attaching portion to which the watch band is attached cannot be secured. There is a problem that it is necessary to form a large mounting portion to ensure the strength, and this causes a problem that the entire timepiece is enlarged.

  In order to solve such a problem, in the conventional wristwatch, the band attaching portion is formed separately from the case main body, and the band attaching portion is attached to the case main body, thereby reducing the size and thickness of the entire watch. A configuration is being developed. In the wristwatch having such a configuration, when the band attaching portion is simply attached to the case main body, the band attaching portion is pushed up by the watch band, so that the position of the band attaching portion needs to be regulated by the bezel.

However, if the bezel is formed of a soft synthetic resin, Since the bezel is deformed when the band attaching portion is pushed up together with the band, there is a problem that a gap is generated between the bezel and the case main body even if there is a buffering effect. Also, if the bezel is made of metal, the bezel will not be deformed when the band mounting part is pushed up together with the watch band, so there will be no gap between the bezel and the case body. There is a problem that it cannot be obtained.

  Therefore, it is considered that the bezel is composed of the first bezel made of soft synthetic resin and the second bezel made of metal, so that both the position regulating effect and the buffering effect of the band mounting portion can be obtained. ing. However, in the configuration in which the first bezel made of soft synthetic resin and the second bezel made of metal are simply combined, when the band mounting part is pushed up together with the watch band, the first bezel made of soft synthetic resin is lifted, There arises a problem that a gap is generated between the first bezel and the metal second bezel.

  The problem to be solved by the present invention is to ensure the strength of the case body made of synthetic resin, and to prevent a shock-absorbing member such as a first bezel made of soft synthetic resin from being deformed and generating a gap. Is to provide.

The present invention includes a synthetic resin case main body provided with a glass mounting portion on an upper portion thereof, a band attachment portion attached to the case main body at 12 o'clock and 6 o'clock direction, and a watch band attached to the band attachment portion. A buffer member made of a soft material that covers the outside of the glass mounting portion of the case body, and an outer periphery of the glass mounting portion of the case body and an inner peripheral side of the buffer member, and locks the buffer member. And a metal ring on which a locking part for restricting deformation of the buffer member is formed, and the locking part of the metal ring is provided at a position corresponding to at least the band mounting part, and the buffer member A wristwatch characterized in that a part of the buffer member is fixed to the case body by being inserted into a recess provided in the case .

  According to the present invention, the strength of the synthetic resin case body and its glass mounting portion can be secured by the metal ring, and the metal ring can be locked when the band mounting portion is pushed up by the watch band. It is possible to prevent the buffer member from being lifted by the portion, thereby preventing the buffer member from being deformed and generating a gap.

  Next, as shown in FIG. 6, the first bezel 12 is attached to the outer periphery of the case body 1. At this time, as shown in FIGS. 2 and 3, the lower portion of the first bezel 12 is disposed on the protrusion 15 provided on the outer peripheral surface of the case main body 1 and is positioned below the metal ring 10. In close contact with the outer peripheral surface of the case body 1, the locking portion 11 of the metal ring 10 is inserted into a recess 12 a provided at the upper portion of the inner peripheral surface of the first bezel 12.

  As a result, as shown in FIGS. 2 and 3, the lower portion of the first bezel 12 is locked by the locking portion 11 of the metal ring 10, and the position of the first bezel 12 is restricted. It is attached. At this time, a space is formed between the upper inner surface of the first bezel 12 and the outer peripheral surface of the metal ring 10 by the upper concave portion 12a on the inner peripheral surface of the first bezel 12, and the first bezel is formed by this space. The upper part of 12 is easily deformed.

  Next, as shown in FIGS. 2, 3, and 7, the second bezel 13 is attached to the outer periphery of the case body 1. At this time, as shown in FIGS. 2 and 3, the upper portion 13 a of the second bezel 13 is formed in a substantially ring shape and is disposed on the upper portion of the glass mounting portion 3, and the upper end surface of the metal ring 10, the first The upper end surface of the bezel 12 and the outer peripheral edge of the upper surface of the watch glass 2 are covered. At this time, the lower portion 13b of the second bezel 13 is in contact with the outer end surface of the protrusion 15 provided on the case body 1 as shown in FIGS. In a state where it can be inserted into the recess 6c provided in the upper part, it is arranged to project obliquely downward.

  Next, as shown in FIG. 7, the metal third bezel 14 is attached between the first bezel 12 and the lower portion 13 b of the second bezel 13. At this time, since the band attaching portion 6 is not attached, as shown in FIGS. 2 and 3, the lower portion 13b of the second bezel 13 is pushed downward to be deformed, and in this state, the third bezel 14 is moved. It arrange | positions between the lower part 13b of the 1st bezel 12 and the 2nd bezel 13.

  That is, at this time, the upper end portion of the third bezel 14 is caused to bite into the upper lower side of the first bezel 12, and the lower end portion of the third bezel 14 is provided on the upper surface of the lower portion 13 b of the second bezel 13. And inserted into the recessed portion 13c. Thus, the third bezel 14 is disposed between the first bezel 12 and the lower portion 13b of the second bezel 13 and exposed to the outside.

  Thereafter, the band attaching portion 6 is attached to the case main body 1. At this time, as shown in FIG. 2 and FIG. 3, the attachment pin 9 is inserted into the case side attachment hole 6a of the band attachment portion 6, and in this state, the band attachment portion 6 is attached to the pair of case main bodies 1 shown in FIG. Arranged between the protrusions 8. At this time, as shown in FIGS. 2 and 3, the lower portion 13 b of the second bezel 13 is inserted into the recess 6 c provided in the upper portion of the band attaching portion 6.

  Then, both end portions of the mounting pin 9 are inserted into the pin mounting holes 8 a of the pair of mounting projections 8 of the case body 1, respectively. Thereby, the band attaching part 6 is attached to the case main body 1 by the attaching pin 9. At this time, the second bezel 13 is pushed up by the band attaching portion 6, and the lower end portion of the metal third bezel 14 inserted into the recess 13 c on the lower portion 13 b is pushed up by the second bezel 13, The upper end portion of the third bezel 14 bites into the upper lower side of the first bezel 12.

  For this reason, as shown in FIGS. 2 and 3, the position of the band attaching portion 6 is regulated by the first to third bezels 12-14. Thereafter, the watch band 7 is attached to the band attaching portion 6. At this time, an attachment pin (not shown) is inserted into the band side attachment hole 6b of the band attachment portion 6 and the watch band 7 is attached to the band attachment portion 6 with this attachment pin.

Next, the operation of this wristwatch will be described.
Usually, the position of the band attaching portion 6 attached to the case body 1 is regulated by the first to third bezels 12 to 14. That is, when the band attaching portion 6 of the case main body 1 is attached, the lower portion 13b of the second bezel 13 is in contact with the outer end portion of the protruding portion 15 of the case main body 1, and the second bezel 13 Since the lower portion 13b of the band attachment portion 6 is inserted into the recess 6c of the band attachment portion 6, the position of the band attachment portion 6 is elastically restricted with respect to the case body 1 by the second bezel 13.

  When the watch band 7 is pushed up in this state, the band attaching portion 6 is pushed up by the watch band 7, and the lower portion 13 b of the second bezel 13 is pushed up by the band attaching portion 6. Then, the lower end portion of the third bezel 14 made of metal inserted into the recess 13c on the lower portion 13b is elastically pushed up by the second bezel 13, and the upper end portion of the third bezel 14 is Is pushed into the upper lower side of the bezel 12.

  At this time, as shown in FIGS. 2 and 3, the lower portion of the first bezel 12 is locked by the locking portion 11 of the metal ring 10, so that the first bezel 12 is moved to the outer periphery of the case body 1. It is attached in a position-controlled state. For this reason, even if the first bezel 12 is pushed up by the third bezel 14 made of metal, the first bezel 12 is not lifted up, and is tightly fixed to the outer periphery of the case body 1.

  At this time, a space is formed between the upper inner surface of the first bezel 12 and the outer peripheral surface of the metal ring 10 by the recess 12a at the upper portion of the first bezel 12, and the first bezel 12 is formed by this space. Since the upper part of the first bezel 12 is pushed up by the third bezel 14 made of metal, the upper part of the first bezel 12 is deformed and the third bezel 14 becomes a gap. Without being generated, it bites well into the upper lower side of the first bezel 12.

  For this reason, even if the band attaching portion 6 is pushed up by the watch band 7, the pushing force can be buffered by the first to third bezels 12 to 14, and by the locking portion 11 of the metal ring 10. Since the first bezel 12 is locked and fixed to the case body 1, the first bezel 12 is not lifted by the pushing-up force of the band attaching portion 6, thereby deforming the first bezel 12. Does not cause a gap.

  Thus, according to this wristwatch, the synthetic resin case main body 1 provided with the glass mounting portion 3, the band attachment portion 6 attached to the case main body 1 in the 12 o'clock direction, and the band attachment The watch band 7 attached to the portion 6, the first bezel 12 covering the outside of the glass mounting portion 3 of the case body 1, and the first bezel 12 fixed to the outer periphery of the glass mounting portion 3 of the case body 1 Since it has the metal ring 10 formed with the locking portion 11 that locks and restricts the deformation of the first bezel 12, the strength of the case body 1 made of synthetic resin can be secured, Generation of a gap due to deformation of the first bezel 12 can be prevented.

  That is, in this wristwatch, the metal ring 10 is fixed to the glass mounting portion 3 of the case main body 1 by press fitting, whereby the synthetic resin case main body 1 and the glass mounting portion 3 are reinforced by the metal ring 10. Thus, the strength of the case body 1 and the glass mounting portion 3 can be sufficiently ensured.

  For this reason, even if the thickness of the glass mounting portion 3 is made thin, the strength of the glass mounting portion 3 can be secured by the metal ring 10, so that the case main body can be formed even if the case main body 1 is formed of synthetic resin. 1 can be miniaturized, and since it is not necessary to insert a metal reinforcing plate in the case body 1 by insert molding as in the prior art, the case body 1 can be easily manufactured and the case body 1 Cost reduction can also be achieved.

  Further, in this wristwatch, since the first bezel 12 is locked by the locking portion 11 of the metal ring 10, when the band attaching portion 6 is pushed up by the watch band 7, It is possible to reliably prevent the first bezel 12 from being lifted by the stop portion 11, thereby reliably and satisfactorily preventing the first bezel 12 from being deformed and generating a gap.

  In this case, the locking portion 11 of the metal ring 10 is provided at least at a position corresponding to the band mounting portion 6, and a lower portion that is a part of the first bezel 12 is fixed to the case body 1. Thus, the first bezel 12 can be securely fixed to the case body 1 without using an adhesive, and the first bezel 12 can be lifted even when the band mounting portion 6 is pushed up by the watch band 7. Can be reliably prevented, and the occurrence of a gap due to the deformation of the first bezel 12 can be reliably and satisfactorily prevented.

  For this reason, since it is not necessary to provide the case body 1 with a stopper portion to prevent the band mounting portion 6 from being pushed up, the case body 1 can be reduced in size and thickness, and the case main body can be reduced by the stopper portion. Since 1 does not receive design restrictions, the case body 1 can be easily formed into a free shape, and the degree of freedom in design can be increased.

  In addition, the wristwatch includes the first bezel 12 that is locked to the case body 1 by the locking portion 11 of the metal ring 10, and is applied to both the case body 1 and the band mounting portion 6. By providing the second bezel 13 made of a soft material such as urethane resin in contact with the case main body 1, the band mounting portion 6 can be elastically and satisfactorily regulated with respect to the case body 1 by the second bezel 13. it can.

  That is, the second bezel 13 has a lower portion 13b that is in contact with the outer end surface of the protrusion 15 of the case body 1 and is inserted into the recess 6c of the band attachment portion 6. 13, the band attaching portion 6 can be elastically and satisfactorily regulated with respect to the case body 1 by the lower portion 13 b, and when the band attaching portion 6 is pushed up by the watch band 7, the pushing force is reduced. It can buffer well.

  Furthermore, since the metal third bezel 14 is disposed between the first bezel 12 and the second bezel 13, when the band attaching portion 6 is pushed up by the watch band 7, The push-up force can be buffered by the first to third bezels 12 to 14, and the generation of gaps due to the deformation of the first to third bezels 12 to 14 can be prevented.

  That is, since the lower part of the first bezel 12 is locked by the locking part 11 of the metal ring 10 and is positioned on the outer periphery of the case body 1, the first bezel 12 is made of metal. 3, the first bezel 12 does not lift up, and the first bezel 12 can be brought into close contact with the outer periphery of the case body 1 and fixed.

  For this reason, a space is formed between the upper inner surface of the first bezel 12 and the outer peripheral surface of the metal ring 10 by the upper concave portion 12a on the inner peripheral surface of the first bezel 12. When the upper portion of the first bezel 12 is pushed up by the third bezel 14 made of metal, the third bezel 14 easily deforms the upper portion of the first bezel 12 and bites well into the lower side of the upper portion. Thus, it is possible to more reliably prevent the occurrence of a gap between the first to third bezels 12 to 14.

  In the above-described embodiment, the case where the locking portion 11 of the metal ring 10 is provided at a location corresponding to the band attachment portion 6 has been described, but it is not necessarily provided only at a location corresponding to the band attachment portion 6. It is not necessary to be provided, and it may be provided continuously over the entire circumference of the metal ring 10.
