[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for removing a register ring of a wristwatch with a register ring.

[0002]

2. Description of the Related Art Conventionally, a register ring removing jig generally used is an open-type jig as shown in a perspective view of FIG.

[0003] Koji opening jig body 6 which is a koji opening jig
Is composed of a metal portion having a claw portion 6a at the tip and a grip portion 6b formed of a plastic material or the like. Is a jig from which the register ring can be removed.

[0004]

In the bite structure, which is a fitting structure between a register ring and a watch case, which has been widely used, it is possible to remove the register ring by the jig opening jig main body 6, but it is strong. Power was required and workability was poor. Further, in the fitting structure constituted by the polygonal spring, it is difficult to remove the fitting unless the fitting force between the register ring and the watch case is reduced significantly. In addition, even if the register ring is detached, a thin register ring is likely to be deformed, and further, there is a problem that the watch case is scratched when the copier is opened. The purpose of the present invention is to solve the above problems and to be applicable to all structures,
An object of the present invention is to provide a jig for removing a register ring, which is less likely to be scratched or deformed and can easily remove the register ring.

[0005]

The structure of the present invention is as follows. The register ring removing jig is composed of a register ring removing jig body 1 having a substantially J-shaped side surface, and a register ring receiving portion 2 exchangeably fixed to the register ring removing jig body 1. , A claw 1 for hooking the lower surface of the register ring 4 to the end of one end
a and an upper surface opposite to the lower surface of the register ring 4, the mounting portion 1 to which the register ring receiving portion 2 is mounted.
c and the register ring detaching jig main body 1 formed with a grip portion 1b at the other end, and the register ring receiving portion 2 made of resin and having a concave portion 2a formed on a surface thereof for receiving the register ring upper surface. , Consisting of

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a side view of a jig for removing a register ring and a watch case with a register ring according to the present invention.
FIG. 4 is a plan view of the register ring removing jig.
Note that the same elements as those in FIG. The register ring detaching jig body 1 formed of metal or the like and having a substantially J-shaped side surface receives a claw portion 1a for hooking the lower surface of the register ring 4 at one end and an upper surface opposite to the lower surface of the register ring 4. A mounting portion 1c to which the register ring receiving portion 2 is mounted and a grip portion 1 at the other end.
b. The register ring receiving portion 2 made of resin or the like and having a concave portion 2 a formed on the surface thereof for receiving the upper surface of the register ring 4 is attached to the register ring removing jig body 1 by a plurality of setscrews 3. 1c. Further, since the mounting portion 1c is an elongated hole from the claw portion 1a toward the grip portion 1b, the mounting position of the register ring receiving portion 2 can be adjusted. Further, the register ring receiving portion 2 has a concave portion 2a which is substantially the same as the outer shape of the register ring 4 to be removed. The concave portion 2a makes it difficult for the register ring 4 to be scratched or the like, and to be easily removed. .

Next, a method for removing the register ring 4 of the watch case 5 using the register ring removing jig of the present invention will be described. As shown in FIG. 1, the claw 1 a of the jig for removing the register ring is hooked on the lower surface of the register ring 4, and the recess 2 of the register ring receiving section 2 is formed.
a is engaged with the register ring 4. Next, the register ring 4 is detached from the timepiece case 5 by grasping the grip portion 1b with a hand and rotating it while applying a force downward.

[0008]

As described above, according to the register ring removing jig of the present invention, when removing the register ring from the watch case, the watch case is hardly scratched. In addition, since the register ring can be removed with a smaller force than the conventional jig opening jig, deformation and the like of the register ring can be prevented, and workability is significantly facilitated. Further, the concave portion 2a of the register ring receiving portion 2
By changing the shape of, it is possible to handle a plurality of models. In particular, the effect of the register ring removing jig of the present invention having a rotating function is greater than that of the conventional jig opening jig for removing the register ring of the register ring fitting structure using a polygonal spring.
