Description

[Detailed description of the invention] <Industrial field of application> This invention relates to a structure for attaching a watch band to a watch case.

<Problems to be solved by this invention> The plate-stack type watch band, which is formed by inserting a large number of plate pieces into a flexible core made of mesh or wire in contact with each other, is conventionally used for attaching watch cases. Since the mounting brackets have been manufactured using nickel silver (NS) or brass (BS), the band and the mounting brackets can only be joined by brazing, which causes wax to seep out from the joints. There was a problem in that the surrounding areas were discolored and the appearance was impaired.

The present invention aims to solve these problems and also to provide a mounting structure that connects the watch band and the watch case as one unit with no gaps.

<Structure of the invention> The present invention provides an exposed portion of the core material at one end of a watch band formed by inserting a large number of plate pieces into a core material, and a top plate and two side pieces are attached to the exposed portion. Attach the mounting bracket by welding by pinching the backing plate, and position the side pieces of the mounting bracket on the outside of the two mounting legs with mounting holes that protrude from both sides of the watch case. A connecting screw hole is provided eccentrically toward the watch band between the sides of the piece, and a conical screw is inserted into the mounting hole through the screw hole to attract and connect the watch case and the watch band to each other. This is due to the structure of the mounting part of the watch band and watch case.

<Example> Examples will be described below based on the drawings.

Two band attachment legs 11, 11 are formed in a protruding manner on both sides of the watch case 10. 12,12
is a mounting hole provided in the center between the sides of the mounting leg.

The plate-stacked type watch band 9 is formed by inserting a large number of plate pieces 9a into a core member 8 and making contact therewith, and leaving an exposed portion 8' of the core member 8 at one end. A mounting bracket 6 formed by attaching a top plate 1 made of stainless steel, for example, which can be welded to this exposed portion 8', and side pieces 4, 4' attached to both ends of the lower tip thereof is sandwiched between a backing plate 7 and spot welded. Attach by. The side pieces 4, 4' attached to both sides of the bottom end of the top plate 1 are attached to the mounting legs 11 of the watch case 10,
Located outside of 11. Connecting screw holes 3, 3' are provided between the sides of the side pieces 4, 4' slightly eccentrically toward the band from the center. In the figure, 2,
2' indicates a conical screw for connection.

Therefore, when connecting the watch band 9 to the watch case 10, the top plate 1 is placed on the mounting legs 11, 11,
It is located on the outside of the side pieces 4, 4' mounting legs 11, 11. The screw holes 3, 3' provided in the side pieces 4, 4 are offset toward the watch band 9 side with respect to the mounting holes 12, 12 due to eccentricity (Fig. 1), and then the conical screws 2, 2' are screwed outward. When screwed into the screw holes 3, 3', the conical screw 2,
The front end of the top plate 1 is attached to the side edge of the watch case 10 in order to attract the screw holes and the mounting holes to each other so that the screw holes and the mounting holes gradually become the same as the tips of the screws 2' enter the mounting holes 12, 12. This connects the watch case and watch band as one unit with no gaps.

When removing the watch band from the watch case 10, the conical screws 2 and 2' are pulled out. Once the connection is released, the watch band can be easily removed from the watch case.

<Effects of the invention> As described above, the present invention has the effect that the mounting bracket is attached to the watch band by spot welding, thereby preventing discoloration due to seepage of wax that conventionally occurs with brazing. will occur. In addition, the connecting screw hole provided between the sides of the side piece of the mounting bracket is slightly eccentric from the center toward the watch band side, so when connecting the watch case and watch band by inserting a conical screw, the connecting screw hole Due to the concentric action of the mounting holes, the watch band and watch case are attracted to each other, producing the effect that they are connected as one unit.
