Abstract

PROBLEM TO BE SOLVED: To prevent the application of strong force to an installing part of a wristwatch case and a connecting member by flexibly bending a band to the wristwatch case. SOLUTION: This band installing structure connects a band piece 14 of an end part of the band 12 to the wristwatch case 1 by the connecting member 13. A first cylindrical part 24 on one end of the connecting member 13 is turnably installed in the wristwatch case 1, a second cylindrical part 25 on the other end is inserted and turnably installed in the band piece 14, and the first and second cylindrical parts 24 and 25 are mutually approached. Thus, when bending the band 12 to the wristwatch case 1, since the connecting member 13 turns with the first cylindrical part 24 as the center and the band piece 14 of the band 12 turns with the second cylindrical part 25 of the connecting member 13 as the center, the band 12 can be flexibly bent to the wristwatch case 1, and since the connecting member 13 and the band piece 14 do not operate as a lever like a conventional example, the strong force is not applied to a spring bar 26.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band mounting structure used in a wristwatch.

[0002]

2. Description of the Related Art Conventionally, in a wristwatch band, a connecting piece is protruded from an end portion of the band and integrally fixed, and the connecting piece is attached to a band attaching portion of a wristwatch case by a spring rod. The connecting piece is rotated to bend the band toward the back side of the wristwatch case.

[0003]

However, in such a band mounting structure, when the band is bent toward the back side of the wristwatch case by rotating the linking piece about the spring rod, the band end or the band is connected. When the piece comes into contact with the lower edge of the wristwatch case or the side surface of the case back, the end portion of the band and the connection piece are not bent because the connection piece is integrally fixed to the end portion of the band.

Therefore, when the band is pressed toward the case back in this state, the end portion of the band or the connecting piece is levered with the end portion of the band or the contact portion of the wristwatch case where the connecting piece abuts as a fulcrum. There is a problem in that a strong force is applied to the spring bar that attaches the connecting piece to the wristwatch case. In particular, if the wristwatch case is made of synthetic resin and the band and the connecting piece are made of metal, the lever of the band and the connecting piece exert a strong force on the spring rod, so that the spring rod is attached to the wristwatch case. There is a problem that the mounting holes are destroyed.

An object of the present invention is to flexibly bend a band with respect to a wristwatch case and to prevent a strong force from being applied to a mounting portion between the wristwatch case and a connecting member.

[0006]

According to a first aspect of the present invention, in a band mounting structure in which a connecting member is attached to an end of a band and the band is connected to a wristwatch case by the connecting member, the connecting member comprises: One end is rotatably attached to the wristwatch case, the other end is inserted into the end of the band and rotatably attached, and the one end and the other end are close to each other. It is characterized by being

According to the present invention, when the band is bent toward the back side of the wristwatch case, the joint member is rotated about one end of the joint member attached to the wristwatch case, and the other member of the joint member is rotated. The end of the band rotates around the end, and at this time, the other end of the connecting member is inserted into the end of the band, and the one end and the other end of the connecting member are close to each other. Therefore, the connecting member does not come into contact with the wristwatch case, but the end portion of the band comes into contact with the wristwatch case. However, since the end portion of the band and the connecting member are relatively rotated and bent, the band is made flexible with respect to the wristwatch case. In addition to being bendable, the end of the band and the connecting member do not act as levers as in the conventional example, and strong force due to the lever's action is not applied to the attachment part between the connecting member and the watch case. You can

According to a second aspect of the invention, in a band mounting structure in which a connecting member is attached to an end of the band and the band is connected to the wristwatch case by the connecting member, the connecting member is made of a bendable material. The one end is fixed in the end of the band, the other end protrudes from the end of the band, and the protruding part is rotatably attached to the wristwatch case. According to the present invention, when the band is bent toward the back side of the wristwatch case, the other end of the connecting member protruding from the end of the band is bent, so that the band can be flexibly bent with respect to the wristwatch case. At the same time, unlike the conventional example, the end portion of the band and the connecting member do not act as levers, and it is possible to prevent a strong force due to the lever action from being applied to the attachment portion between the connecting member and the wristwatch case.

In this case, at least the end portion of the band is covered with a metal plate, so that the other end portion of the connecting member attached to the end portion of the band is covered with the metal plate. It is possible to hide the other end of the connecting member from the outside.
