Thus, even of the shape and kind of the band is varied, only the shape of the fitting piece 21 is changed, and the band body and the cover member 20 or the like can be prevented from being restricted by the shape and structure of the band body and the cover member 20 of the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a band such as a watch band.

[0002]

2. Description of the Related Art In general, some watch bands have a band body formed of a synthetic resin such as urethane. In such a timepiece band, if one end of the band body is directly attached to the band attachment portion of the wristwatch with a spring bar or the like, the band body is made of a synthetic resin such as urethane, so that sufficient attachment strength cannot be secured. For this reason, conventionally, a product in which a metal attachment member is integrally attached to one end of a synthetic resin band main body has been commercialized. The attachment member of the watch band has a structure in which a cover portion covering one end of the band main body and an attachment portion attached to the band attachment portion of the wristwatch are integrally formed of a metal plate.

[0003]

However, in such a watch band, the metal mounting member has a structure in which the cover portion and the mounting portion are integrally formed, and the mounting member is attached to one end of the band body. Since they must be mounted integrally, the mounting members are subject to restrictions on their shape and structure. For this reason, it is necessary to manufacture mounting members that match the size and type of the band or the size and shape of the watch. There is a problem that it must be integrally attached to the band body.

An object of the present invention is to form a cover member corresponding to a cover portion and a mounting piece corresponding to a mounting portion as separate parts so that they can be fixed to each other. The goal is to not be restricted by shape or structure.

[0005]

According to the first aspect of the present invention,
A non-metallic band body having a notch at one end,
A metal piece provided in the notch of the band body,
A metal cover member provided on the one end of the band body to cover the front and back surfaces and the metal piece, and a metal attachment piece fixed to the cover member at a position corresponding to the metal piece. It is characterized by having. The invention according to claim 2 is a non-metallic band main body, a metal cover member provided on one end of the band main body so as to cover the front and back surfaces thereof, and a metal fixed to the cover member by spot welding. And a metal piece provided on the band body positioned between the front and back surfaces of the cover member corresponding to the spot to be spot-welded.
According to the present invention, when attaching the metal attachment piece to the metal cover member provided at one end of the band body, the cover members located on the front and back surfaces of the band body come into contact with the metal piece to conduct electricity. By arranging the mounting piece on the cover member corresponding to the metal piece, spot welding of the mounting piece to the cover member becomes possible without destroying the non-metallic band body. Even if the band and the mounting piece are formed separately, both can be securely and firmly fixed by spot welding, and even if the shape or type of the band changes, just change the shape of the mounting piece only, The band main body, the cover member, and the like can hardly be restricted by the shape and the structure.
