Description

[Detailed description of the invention] <Industrial field of application> This invention consists of a connecting hole provided in the engaging part of the pieces that make up the watch band, and a connecting hole in the engaging part provided in the tip member of the band for attachment to the watch side. This invention relates to a watch band connecting device in which a connecting pin is inserted into the watch band.

<Problems to be solved by this invention> Conventionally, in this type of connecting device, a pin was formed with a diameter slightly larger than the connecting hole and was press-fitted into the connecting hole, or
A method was adopted in which a thread was carved into the connecting hole and a threaded pin was screwed into it, or screws were inserted into both ends of the connecting hole to seal the pin inserted into the connecting hole.

However, the method of forming a pin with a large diameter and press-fitting it into the connecting hole fixes the connecting hole and the pin integrally, which prevents smooth bending, stretching, and bending between the pieces and between the band and the watch side. There were problems in that the watch band lost its suppleness and that it was completely impossible to adjust the band length by removing the pin.

In addition, when screwing a threaded pin and a sealing screw into a connecting hole, the connecting hole also rotates as the bridge pieces and the tip part rotate during use. There was a problem in that the threaded pin and the sealing pin also rotated in conjunction with each other, loosened, and were pulled out, causing the sealing pin to fall off.

The present invention attempts to solve these problems.

<Structure of the invention> The present invention uses a pin in a connecting hole formed transversely between the meshing part between the pieces 11 constituting the band 1 and the meshing part between the tip part 2 and the watch side 3 provided at the base end of the band 1. In a watch band connecting device in which the band 1 is formed by inserting and fitting the pieces 11 to connect the pieces 11 and connecting the band 1 and the watch side 3, the pieces 11 and the tip member 2 are connected. Screw holes are provided vertically that reach the connecting holes from both ends of the front surface or the back surface facing the holes, and the pins that are inserted into each of the connecting holes can be freely pulled out by the screws that are screwed into the screw holes and inserted into the connecting holes. A watch band connecting device is characterized in that it is sealed.

<Example> The example will be explained below with reference to the drawings.

Connecting holes 12 and 13 are formed across the side surfaces of the pieces 11, which are formed into an interlocking shape with a convex portion on one side and a recess on the other side, and the connecting holes of each piece 11 A connecting pin 10 that is inserted between the screw holes 15 of each connecting hole 13, with screw holes 15 vertically arranged to reach the connecting hole 13 from both ends of the front side or the back side facing the connecting hole 13.
Connecting hole 13 by screw 9 screwing into screw hole 15
It was designed to be sealed inside. In the figure, reference numerals 14 indicate openings at both ends of the connecting hole 13 that appear at the side ends of the piece 11.

Also, a tip member 2 connected to the base end of the band 1
is provided with a concave engaging part in plan view that engages with the foot lever 4 with the mounting hole 6 of the watch side 3 in the center, and a connecting hole 5 passing through this engaging part is formed in a transverse manner, and the surface facing the connecting hole 5 is Also, a screw hole 8 is provided that reaches the connecting hole 5 from both ends of the back surface, and a pin 10 that is inserted between the screw holes 8 of the connecting hole 5 is sealed in the connecting hole 5 by a screw 9 that is screwed into the screw hole 8. I tried to stop it.

With the above structure, the links 11 of the band 1 and the band 1 and the watch case 3 can freely rotate around the pins sealed by the screws 9. Also, when it is necessary to separate the links 11 to adjust the shortening of the band 1 or when it is necessary to remove the watch case 3 from the band 1, it is easy to do so because the pins 10 can be immediately removed by loosening and removing the screws 9.

<Effects of the invention> As described above, in the present invention, the connecting pin inserted into the connecting hole is sealed with a screw, so there is a margin between the connecting hole and the pin to allow free rotation. This has the effect of imparting flexibility to the band. Moreover, since the screw is screwed into the front or back side of the bridge piece and the tip member, even if the connecting hole rotates with the bending, extension, bending, and bending of the bridge piece and the tip member, it will never loosen or come out. This has the effect of eliminating the risk of the connecting pin falling off and allowing stable use for a long period of time.

Furthermore, when the screw is screwed from the surface of the bridge piece and the tip member, the grooved screw heads are exposed in parallel, giving the band a beautiful design.
