Description

[Detailed Description of the Invention] This invention relates to a watch band formed by connecting a required number of cylindrical bridge bodies with flexible support bands.

Conventionally, this type of watch band has been made by forming insertion holes, for example, at different positions on the circumferential surface of a round pipe made of a metal material, through which a flexible support band such as a metal mesh band is inserted. It is known that a watch band is formed by connecting a plurality of piece bodies using their supporting bands.

By the way, in order to form an insertion hole in this piece body through which the support band is inserted, it is necessary to use a cutting force because the piece body is in the shape of a round pipe. Forming the insertion hole at the center of the plane is relatively easy, although some distortion or deformation occurs in the piece body.

However, it has been impossible to cut the insertion hole at a position slightly deviated from this because the distortion and deformation described above will become large.

Moreover, even when this insertion hole is passed through the center of the bridge body, a portion of the support band is exposed from the surface, which significantly impairs the design effect of the watch band itself.

This idea was made in view of the above circumstances,
The purpose is to provide a watch band whose piece bodies are easy to process and whose design effect is enhanced by preventing the supporting bands connecting the piece bodies from appearing between the piece bodies. be.

This invention will be explained in detail based on the embodiment shown in the drawings.

Figures 1 to 5 show the first embodiment of the watch band according to this invention. In the figures, the number 1 indicates the piece body, the number 2 indicates the side piece, and the number 3 indicates the support. It is an obi.

The piece body 1 is formed by roll forming a rectangular metal plate 4 shown in FIG. 4 into a round pipe shape as shown in FIG. Notches 5A and 6 of a size corresponding to the width and thickness (cross-sectional shape) of the support band 30 are formed in advance by Roe et al., and when these are formed into a round pipe shape as described above. The notches 5 and 6 correspond to the circumferential surface of the piece body 10 at positions offset from the center of the cross section, thereby forming insertion holes 5a and 6a.

The side pieces 2 are used to close both sides of the piece body 10 to form both sides of the watch band in the width direction. and a fitting portion 2b that is tightly fitted (forcibly fitted) to the fitting portion 2b.

Furthermore, the outer diameter of the head 2a of the side piece 2 and the outer diameter of the piece body 1 are both formed to be equal, so that no step is formed at the joint between the two.

In this embodiment, the support band 3 is made of a flexible band-shaped member such as a metal mesh band, and by inserting the support band 3 into the insertion holes 5a and 6a of the piece body 1, The main bodies 1 are connected in sequence.

Next, to explain the case of connecting each member arranged in this way, the support band 3 is inserted into the insertion holes 5a and 6a of a plurality of piece bodies 1°...
．． After connecting multiple pieces..., the piece bodies 1. ...
Side pieces 2. . . are temporarily fitted, press in the width direction of the band (lengthwise direction of the bridge body 1), and thereby the side bridges 2. ... as the piece body 1. ... and assembled into a watch band as shown in Figures 1 and 2.

Note that the means for fixing the plurality of piece bodies to the support band 3 include fixing the back side by spot welding or the like, or using a stopper (not shown) for the watch body attached to one end of the support band 3 and a support. It may be fixed from both ends with a stopper (not shown) attached to the other end of the band 3, or by other means.

In the watch band assembled in this way, the circumferential sides of the adjacent bridge bodies 1 are in contact with each other, so when the watch band is viewed from the front side, the supporting band 3 used for connecting the bridge bodies 1 is visible. It looks very good because it does not appear on the surface like in the past.

In addition, to form the piece body 1, a metal plate material in which insertion holes 5 and 6 through which the support band 3 is inserted is formed in advance by a method such as roll forming. Not only is there no distortion or deformation that occurs when cutting the insertion hole to form the insertion hole, but the piece body 1 is extremely easy to form.

Furthermore, in this invention, the piece body 1 is shaped like a round pipe, and the head 2a of the side pieces 2 fitted on both sides of the round pipe-shaped piece body 1 is also formed into a hemispherical shape. The formed watch band has no sharp edges throughout, so it will not damage skin or clothing.

FIG. 6 shows a second embodiment of this invention, in which the piece main body 1 shown in the first embodiment is made into a pipe with an elliptical cross section instead of being shaped like a round pipe. The piece main body γ, which is a shaped pipe, is also processed and formed by the method shown in the first embodiment, and its operation is the same as that in the first embodiment.

Note that the side pieces fitted on both sides of the piece body 7 are naturally formed in a shape corresponding to the shape of the piece body 7.

FIG. 7 shows a third embodiment of this invention. In this embodiment, the length of each piece body 1 is changed as necessary, and the outer shape of the watch band when viewed from the front and back sides is varied. The design effect is enhanced by adding

It should be noted that this embodiment can also be easily applied to the second embodiment described above.

In the above-ground embodiment, the shape of the piece body was formed into a round pipe shape and the shape was formed into a pipe with an elliptical cross section, but in short, multiple piece bodies are connected with a support band. The present invention is not limited to the above-described embodiments, as long as the supporting band is not visible from the surface side of the watch band when the watch band is formed.

As described in detail above, the watch band according to this invention is made by forming the main body of a metal plate into a pipe shape by roll forming, etc., in which insertion holes corresponding to the cross-sectional shape of the support band are formed, and the insertion holes are formed in advance. Since they are formed at positions offset from the cross-sectional center of the bridge body, when this watch band is viewed from the front side, the support band connecting the bridge bodies does not appear between the bridge bodies, and the watch band is Therefore, the design effect of the watch band itself can be enhanced, and the piece itself can be easily processed, which is an excellent effect.
