Description

[Detailed Description of the Invention] The present invention relates to a register ring click device for a wristwatch that selectively positions the register ring of a wristwatch using a click member, and its purpose is to press and rotate the register ring. This is to ensure that the register ring can rotate smoothly without tilting.

As shown in FIG. 1, the conventional wristwatch register ring click device has a plurality of coil springs 2 inserted into holes 1b drilled at regular intervals in the bottom of an annular groove 1a formed in a body 1, and a ball 3 attached to the upper end of the holes 1b. Since the balls 3 were pressed against a number of engagement grooves 4a formed on the lower surface of the register ring 4 which was mounted and rotatably fitted into the ring groove 1a, when the register ring 4 was pressed, only the springs in the pressed portions were released. There was a drawback that the entire register ring did not descend uniformly when pressed, and the register ring tended to tilt, and a portion of the register ring came into pressure contact with the side of the ring groove, making it difficult to rotate smoothly.

The present invention eliminates the drawbacks of the conventional method by connecting a plurality of click pins with a support ring.

2 and 3 show an embodiment of the present invention.
0 is a truncated cone-shaped click pin with an engagement rod 1 at the lower end
11 is a circular groove 12a of the body 12.
The engaging rods 10a of the click pins are inserted from above into a number of through holes 11a formed at equal intervals in a support ring that fits into the annular groove 12a, and the engaging rods 10a are inserted into coil springs 13 whose lower parts are inserted into small holes 12c at the bottom of the annular groove 12a corresponding to the click pins 10, and the click pins 10 are pressed against a number of engaging grooves 14a formed on the underside of a register ring 14 that is fitted rotatably above the annular groove 12a.
Reference numeral 15 denotes a glass which is fitted and fixed to the upper inside part of the case 12 via a packing 16, and reference numeral 17 denotes a back cover.

Next, the effect will be explained.

The click pin 10 is constantly pushed into the register ring 14 via the support ring 11 by the elasticity of the spring 13.
The register ring 14 is fitted into the groove 14a on the lower surface.
is pressed upward, so that the engagement protrusion 14b on the inner surface of the register ring 14 engages the engagement protrusion 1 on the upper part of the annular groove 12a.
2b to prevent rotation of the register ring 14. When register ring 14 is pushed downward, click pin 10 is also pushed downward, and support ring 11 is also pushed downward together. Therefore, the other click pins 10 are also lowered uniformly at the same time, and the entire register ring 14 is lowered without tilting, and the engaging protrusion 14b is separated from the engaging protrusion 12b of the body 12 over the entire circumference, so that the register is closed. The ring 14 can be rotated smoothly. register ring 1
When you release your hand from 4, the spring 13 returns to its original position.

According to the present invention, a plurality of click pins are connected by a support ring, so when the register ring is pressed downward, all the click pins descend uniformly and the register ring does not tilt, allowing smooth rotation.
