Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a metal wristwatch band.

[0002]

2. Description of the Related Art As shown in FIG. 6, for example, a conventional metal wristwatch band has front-side pieces 10 and back-side pieces 11 alternately arranged in the lengthwise direction.
Are connected by a U-shaped connecting pin 12.

[0003] The conventional metal wristwatch band having the above-mentioned structure is unsatisfactory in that it has insufficient elasticity and is difficult to be attached to and detached from the arm due to restrictions on the shape of the top and the connection structure between the tops. There is.

SUMMARY OF THE INVENTION An object of the present invention is to provide a metal wristwatch band which has sufficient elasticity and can be easily attached to and detached from an arm.

[0005]

The above object is achieved by the present invention, that is, the narrow band-shaped metal plate 4 has a figure-eight shape when viewed from the side, and has a front ring portion 5 and a back ring portion 6.
Are bent so that they are alternately continuous while being shifted in the width direction, and the front ring portion 5 and the back ring portion 6 are formed so as to be arranged in series at a constant pitch in the width direction, respectively. 1 and sub-pieces 2 having the same structure as the main piece 1 and turned upside down are alternately arranged in the length direction, and at one end in the width direction, the front-side ring portion 5 of the main piece 1 and its A side (long side). The front side ring portion 8 of the sub-piece 2 located in one side of the main piece 1 and the back side ring portion 6 of the main piece 1 and its B side (refer to the opposite direction to the A side). The back-side ring portions 9 of the sub-piece 2 located overlap with each other, and the front-side ring portion 5 of the main piece 1 and the front-side ring portion 8 of the sub-piece 2 positioned on the B side thereof at the other end in the width direction. 1 on the back side ring part 6 and its A side The back side ring portions 9 of the sub-pieces 2 to be placed are arranged so as to overlap each other, and substantially U-shaped with respect to the front side ring portion 5 of the main piece 1 and the front side ring portion 8 of the sub-piece 2 which overlap each other at both ends in the width direction. Insert one end of the locking pin 3 bent into a shape,
The other end of the locking pin 3 is inserted into the back side ring portion 6 of the other main piece 1 adjacent to the main piece 1 and the back side ring portion 9 of the sub piece 2 overlapping therewith, so that each main piece 1 and each sub The present invention can be achieved by a metal wristwatch band in which the piece 2 and the piece 2 are integrally connected.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 shows a main piece 1 and a locking pin 3. The main piece 1 is formed so that the narrow band-shaped metal plate 4 has a figure-eight shape when viewed from the side, and the front side ring portions 5 and the back side ring portions 6 are alternately continuous while being shifted in the width direction. The structure is such that the front side ring portion 5 and the back side ring portion 6 are arranged in series at a constant pitch in the width direction, that is, a figure-eight spiral structure.

The locking pin 3 is formed by bending a metal wire into a substantially U-shape. One end of the locking pin 3 has a straight rod shape, and the other end has a locking portion 7 bent in a U-shape in the middle. Provided.

In addition, there is also provided a sub-piece 2 having the same structure as the above-mentioned main piece 1 and turned upside down. That is,
The auxiliary piece 2 is the same as the main piece 1 and can be used with the main piece 1 turned upside down.

The metal wristwatch band of the present invention comprises the above three components, namely, a main piece 1, a sub piece 2, and a locking pin 3.
And is assembled. FIG. 2 to FIG.
The figure shows a state in which a band is formed by assembling members. As shown in FIGS. 4 and 5, the main piece 1 and the sub-piece 2 are alternately arranged in the length direction, and the front-side ring portion 5 of the main piece 1 and the sub-piece located on the left side thereof at one end in the width direction. 2 has a back ring portion 6 of the main piece 1 and a back ring portion 9 of the sub piece 2 located on the right side thereof.
Overlap with each other (see FIG. 3), and the front side ring portion 5 of the main piece 1 and the front side ring portion 8 of the sub-piece 2 located on the right side thereof at the other end in the width direction, and the back side ring portion 6 of the main piece 1 The rear ring portions 9 of the sub-piece 2 located on the left side thereof are arranged so as to overlap with each other. 4 and 5 show only the front-side ring portions 5 and 8 of the main piece 1 and the sub-piece 2, and the back-side ring portions 6 and 9 are omitted.

Then, as shown in FIG. 3, one end of the locking pin 3 is attached to the front side ring portion 5 of the main piece 1 and the front side ring portion 8 of the sub piece 2 which are overlapped with each other at both ends in the width direction. And the other end of the locking pin 3 is inserted and locked into the back side ring portion 6 of the other main piece 1 adjacent to the main piece 1 and the back side ring portion 9 of the sub-piece 2 overlapping therewith. Thereby, each main piece 1 and each sub piece 2 are integrally connected. That is, in the metal wristwatch band of the present invention, the main piece 1 and the sub piece 2 are connected in a substantially zigzag shape at both ends in the width direction.

[0011]

The metal wristwatch band of the present invention is as described above, the main piece 1 and the sub-piece 2 are connected in a substantially zigzag manner at both ends in the width direction, and both the main piece 1 and the sub-piece 2 are connected together. The arms are connected so that they can be inclined in the longitudinal direction, and the main piece 1 and the sub-piece 2 each have a spring elasticity and have a shape that is easily deformed. It has the effect that it fits easily and can be easily attached to and detached from the arm. Also, both the main piece 1 and the sub piece 2 have a figure-eight spiral structure, and there are no corners or joints as in the conventional product, and the arc-shaped portions of the back ring portions 6, 9 touch the arms, Tactile feeling is also good. Also, the main piece 1 and the sub piece 2 have the same structure, and the front side ring portions 5, 8 and the back side ring portions 6, 9 are integrally formed. There is an advantage that the number of parts is reduced and the assembling is facilitated without troublesome connection with the eleventh embodiment. In the metal wristwatch band of the present invention, since the main piece 1 and the sub-piece 2 are connected in a substantially zigzag manner at both ends in the width direction as described above, lateral bending is easy.
