Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wristwatch which allows a user to change the side of the timepiece by himself / herself according to clothes and the like in order to enhance fashionability.

[0002]

2. Description of the Related Art In recent years, watches have been positioned as an important element of fashion, and watches of various designs have been provided. However, it is necessary to purchase a watch that suits the fashion of each time. Would impose a significant financial burden on the buyer. In order to easily match the fashion, it is necessary to replace the band of the watch, but it is not so easy to replace the band, and even if only the band is replaced, the impression of the watch does not change so much.

There is also provided a band and a case which are integrally formed in order to obtain a smart design. For example, in Japanese Utility Model Laid-Open No. 61-67588, a case (watch side) in which a band is integrally formed is made of an elastomer so as to cover an inner case integrally formed with a cover glass. According to this structure, in addition to the fact that the design and the structure can be made into a clean shape, the elastic property of the band-integrated case also makes it easy to assemble it on the body. However, this is just a matter of assembling the timepiece on the side of the manufacturer, and it was not possible for the user to freely exchange the timepiece side (case) with his or her own preference.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a wristwatch in which the user can easily replace the timepiece by himself.

[0005]

In order to achieve the above object, the characteristics of the wristwatch according to the present invention are as follows: a watch mechanical body, an inner case that functions as a storage case for the watch mechanical body, and an outer peripheral side surface of the inner case. The inner case is made of a transparent hard resin, the front cover part, the side wall part of the outer peripheral part of the front cover part, and the outer peripheral surface of the side wall part. The protruding portion for preventing falling is integrally formed, and the side of the timepiece is made of an opaque soft resin to cover the side wall portion and the inner surface of the decorative portion. An engaging recess formed to be detachable from the protrusion of the inner case, and a band portion extending from the outer periphery of the decorative portion are integrally formed, The watch mechanical body includes the side wall portion of the inner case and the side wall portion of the inner case. It is a type that does not have a member such as a crown protruding through the decorative portion on the side of the meter in the side surface portion, and the side of the timepiece is formed by pulling the band portion to connect the protrusion and the engaging recess. It is in a place where it can be detached from the side wall portion of the inner case by releasing the engagement.

DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in FIGS. 1 and 2, a wristwatch according to the invention comprises an inner case 1 and a watch side 2.

The inner case 1 is integrally formed of a transparent hard synthetic resin so as to function as a timepiece machine body storage case for storing a timepiece machine body (not shown). A side wall portion (inner body) 1b having an arcuate step is formed integrally therewith. From the outer peripheral portion of the side wall portion 1b, two protruding portions 1c, 1c for preventing falling are formed so as to protrude in the radial direction in a positional relationship of facing each other.

The side 2 of the timepiece is a molded product integrally formed of an opaque soft synthetic resin, and has a decorative portion 2a which is an important element of the appearance of the timepiece and a concave portion formed on the inner surface of this decorative portion. 2c and a band portion 2b integrally extending from the outer peripheral portion of the decorative portion. The decorative portion 2a is detachably attached to the outer peripheral surface of the side wall portion 1b of the inner case 1. Further, the concave portion 2c is formed on the inner surface of the decorative portion 2a so as to correspond to the formation position of the band portion 2b, and is formed so as to be detachable from the protruding portion 1c of the inner case 1. The engagement between the projection 1c of the inner case 1 and the recess 2c of the decorative portion 2a prevents the side 2 of the timepiece from falling off the inner case 1.

The inner case 1 and the timepiece side 2 are formed by molding the front glass 1a, the side wall portion 1b and the protrusion 1c constituting the inner case 1 after molding them with a transparent hard synthetic resin. The front glass or the like is left as it is in the mold for molding, and the side 2 of the timepiece is injection-molded later, that is, a so-called two-color molding method, in which an opaque soft synthetic resin is injected and integrally molded. At the time of this two-color molding, a resin having a poor heat-sealing property with respect to the material of the inner case 1, that is, a resin having excellent peeling property with respect to the material of the inner case 1 is used as the material of the timepiece side 2. As an example of this combination, when the material of the inner case 1 is acrylic resin, the olefin resin is suitable as the material of the timepiece side 2.

According to such resin selection, the inner case 1 and the timepiece side 2 are excellent in mutual releasability after two-color molding and can be easily separated later even if two-color molding is performed integrally. Further, since the side 2 of the timepiece is made of a soft material, it can be easily expanded and contracted, and by strongly pulling the band portion 2b outward, the concave portion 2 of the decorative portion 2a can be obtained.
The side 2 of the timepiece can be easily attached to and detached from the inner case 1 by disengaging or aligning the protrusion c with the protrusion 1c. Of course, it is obvious that the type of timepiece mechanical body must have no crown or other member on its side surface, as is apparent from the drawings. If there is a member such as a crown that protrudes through the side surface portion 1b of the inner case 1 and the decorative portion 2a of the timepiece side 2, it becomes difficult for the user to replace the timepiece side by himself. Is.

Therefore, a user who purchases the wristwatch according to the present invention can easily exchange the watch side 2 with another watch side having a different color or pattern according to his / her preference. it can.

[0012]

With the structure of the wristwatch according to the present invention, when it is desired to change the atmosphere created by the timepiece according to the clothes,
The side of the watch, which occupies an important part of the appearance of the watch, can be easily exchanged by the user with his / her own favorite color or pattern, and the side of the watch is
Since the band portion is integrally formed of the synthetic resin, it can be provided as a replacement part at a low cost, and thus the user is not burdened with a large financial burden.
