Description

[Detailed description of the invention] [Industrial application field] The invention is applicable to rings, pendants, bracelets,
This invention relates to a device for attaching an electronic watch to ornaments such as brooches and buckles.

[Prior art]

Conventionally, when attaching an electronic watch to an ornament such as a ring, the electronic watch is fixed to the inserted part provided on the ornament by screwing, or the electronic watch is attached to the inserted part by caulking the rear part of the ornament. It was fixed.
However, in the case of the former screw fixation, it is necessary to form a female thread part on the inserted part and a male thread part on the outer surface of the electronic watch, which takes time and effort to manufacture, and requires both thread parts to be high. The drawback was that if it was not finished with precision, it would cause wobbling. Furthermore, in the case of the latter caulking structure, it is impossible to replace the electronic timepiece, making it impossible to continue using the electronic timepiece by replacing the battery, and the electronic timepiece itself cannot be replaced, making it easy to get tired of it.

[Problem that the invention attempts to solve]

The present invention aims to solve the problems that it takes time and effort to manufacture a device for attaching an electronic watch to a decorative item and that it is prone to rattling, as well as the problem that it is easy to get tired of the electronic watch because it cannot be replaced. It is.

[Means and actions for solving problems]

The present invention provides an inclined part that widens forward in the inserted part of the electronic watch that faces the rear outer periphery when the electronic watch is inserted, and press-fits an end ring into the inclined part. , converting the inward compressive force that the end ring receives from the inclined portion into an urging force that presses the electronic watch forward;
This biasing force is used to fix the electronic timepiece to the inserted part of the ornament.

[Example of idea]

Hereinafter, the present invention will be explained in detail based on the embodiments shown in the drawings. Figure 1 is a plan view of the ornament according to the present invention;
FIG. 2 is a bottom view of the same, FIG. 3 is a vertical cross-sectional view of the same, and FIG. 4 is a plan view of the end ring according to the present invention. In the figure, reference numeral 1 denotes an ornament, and the ornament 1 is a ring, and a circular hole-shaped insertion portion 2 is provided in the center. The insertion portion 2 is for inserting an electronic timepiece 3, has a stepped portion 4, and is formed so that the electronic timepiece 3 cannot be removed from the front. A sloped portion 6 that widens toward the front is provided around the insertion portion 2 at a portion facing the rear outer periphery 5 of the electronic timepiece 3 when the electronic timepiece 3 is inserted. Incidentally, the inclined portions 6 may not be formed over the entire circumference, but may be provided protrudingly at appropriate intervals. Further, the inclined surface of the inclined portion 6 may be a flat surface, but if it is formed into a concave shape as shown in the figure, it becomes easier to press-fit an end ring 7, which will be described later.
The end ring 7 has an end portion 8, which is obtained by cutting off a portion of the ring body.
9, and is formed to be compressible and deformable. The outer diameter of the end ring 7 is slightly larger than the maximum diameter portion of the inclined portion 6. Ended ring 7
Small holes 10 and 11 are formed in the ends 8 and 9 of the ring 7, and the end ring 7 is formed to be easily compressed and deformed by inserting separate pins (not shown) into the small holes 10 and 11. are doing. 12, 12... is ornament 1
13 shows the crown of the electronic watch 3.

Next, the operation of the above embodiment will be explained. After inserting the electronic timepiece 3 into the inserted part 2 of the ornament 1, the end ring 7 is press-fitted into the inclined part 6 of the inserted part 2. As a result, the end ring 7 receives an inward compressive force from the inclined portion 6, and this compressive force is converted into an urging force that presses the electronic watch 3 forward, thereby fixing the electronic watch to the inserted portion 2. . When removing electronic clock 3,
It is only necessary to first remove the end ring 7 by compressing the ends 8, 9 of the end ring 7 in the approaching direction.

[Effect of idea]

According to the present invention, an inclined portion that widens forward is provided in the inserted portion of the electronic timepiece that faces the outer periphery of the rear surface when the electronic timepiece is inserted, and an end ring of the inclined portion is press-fitted. With this, it is only necessary to form the sloped part on the ornament and to separately form an end ring of a size that is press-fitted into the sloped part, so that manufacturing is simple, and
Since the electronic timepiece is fixed using a biasing force based on compressive deformation, it is possible to prevent the electronic timepiece from wobbling without having to manufacture it with high precision.
Furthermore, since the electronic timepiece can be replaced by removing the end ring, it is difficult to get tired of the electronic timepiece, and it is possible to continue using it by replacing the battery.
