Description

DETAILED DESCRIPTION OF THE INVENTION 3. A detailed description of the present invention relates to a meno/yu band for a wristwatch in which a wire is wound into an oval or elliptical coil, and particularly relates to a herringbone band and herringbone band structure.

Conventional herringbone and gundo will be explained with reference to FIGS. 1 and 2. The conventional herringbone band 11 consists of left and right coils 5 and 6 with different winding directions, which are alternately assembled and connected via pins 3.
To prevent the pin 3 from being removed and to process the band both sides 9, bend both ends of the coils 5 and 6 inward, use the bent coil ends to prevent the pin 3 from being removed, and process the band both sides 9. Either you can make the bent part of the coil smooth by positioning it on the side of the band, or you can braze the end of the coil to prevent the pin 3 from coming out and make both sides 9 of the coil smooth. By pressing and crushing the coils 5 and 6 incorporating the herringbone band 11 in the thickness direction, the pin 3 is bent inside the coil 5 and 6 to prevent it from being pulled out, and the side surface 9 of the band is treated by polishing. The method etc. The method of bending both ends of the coil inside the coil and the method of brazing the ends of the coil are both complicated processing methods and require a large number of processing steps, so they are limited to high-priced products made from precious metals. This is a processing method that cannot be used when stainless steel is used as the material. Furthermore, the method of crushing the coils 5 and 6 by press processing impairs the elegance of the top surface of the herringbone band and the flexibility of the band, and is therefore a processing method that cannot be used for luxury wristwatches. Furthermore, the menosh band connects the coils 5 and 6 with pin/3, and the pin 3 has a structure or processing method that prevents it from coming out easily, so if you want to adjust the length of the band, you can generally cut it at the required length position. It is taken.

Therefore, once the cut length has been adjusted, it is impossible to adjust the length again, and there has been a strong demand for a block band piece to have a length adjustment function.

The present invention was made in view of the above drawbacks, and aims to provide a mesh band for luxury watches that maintains the elegance of herringbone coils, is easy to manufacture, and allows the length of the band to be adjusted. The gist of the present invention to achieve the above object is to provide a herringbone band 13 that connects left and right coils 5 and 6 with different winding directions via a pin 3, and an edge piece that is provided with a hole 7 that fits with the pin 3. 1 is attached to both sides 10 of the coil end.The band length adjustment part is made by using a screw 4 on one side of the pin 3 and a hole 7 in the edge piece 2 that fits with the pin 3 to adjust the length of the band. The reason is that it allows for adjustment. The explanation will be given below based on FIGS. 1 to 5. The case of a herringbone pattern in which one coil 5 or 6 is coupled to two pins in FIG. 1 will be described in detail. FIG. 2 is a plan view of a conventional herringbone band 11, and FIG. 3 is a plan view of a herringbone band 12 with edge pieces of the present invention.
FIG. 4 is a plan view of the herringbone band 13 in a state before the edge pieces 1 and 2 of the herringbone band 12 with edge pieces of the present invention are attached.
FIG. 5 is a perspective view of the herringbone band with edge pieces of the present invention. In FIGS. 4 and 5, the herringbone band 13 is made by connecting left and right coils 5 and 6 with different winding directions by pins 3 at mutually interlocking positions, and then pressing the coils 5 and 6 into the herringbone band profile.・It has both side surfaces 10 of the coil end which are pressure-formed from the lateral direction of the gun. The edge pieces 1 and 2 have a width that is approximately equal to the long axis of the coils 5 and 6.
The edge piece 1 has a hole 7 that fits with the pin 3, and the edge piece 2 has a hole 7 that fits with the pin 3 and a hole 8 that screws with the screw 4. and one hole each.

The length "L" of the pin 3 is 0.2 to 0.4 from the value 2b of two widths of the edge piece 1 at each position from both sides 10 of the coil end.
After the edge piece 1 is press-fitted, the outside of the edge piece 1 is polished and the excess head of the pin 3 is removed.

Figure 5 shows pin 3 on pin 3 of the herringbone band 13 in the figure.
A part to which the edge piece 1 having a hole 7 to be fitted is press-fitted;
It is a perspective view showing the whole of the herringbone band with edge pieces, which consists of an adjustment part whose length can be adjusted with screws 4, and the adjustment part is
One set of coils 5 and 6 combined with one adjustment unit block 14
It consists of a connecting via 3 and a piece 2 press-fitted at both ends of the pin 3, which has a hole 7 that fits the pin 3 and a hole 8 that screws the screw 4. It consists of unit blocks 14 that can be used.

The method of connecting the adjustment unit blocks 14 is to connect adjacent coils 5,
6 are combined, and a set of screws 4 are passed through the coils 5 and 6 from both sides of the band to connect them. When removing the adjustment unit block 14, the connection is released by removing one set of screws 4 from the edge piece 2.

By attaching the edge pieces 1 and 2 to the herringbone band 13 in this way, the drawbacks of the herringbone band 11 can be compensated for, the elegance of the herringbone band can be maintained, and the band side and band length can be adjusted at the same time as the block band. There are advantages. Furthermore, by changing the nature of the herringbone/gu/do and the edge pieces, and by using different surface treatments, it is possible to change the appearance and add diversity to the design.
