Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea concerns the structure of parts such as the crown that perform internal operations for watches. be.

0002

[Conventional technology]

Conventionally, as shown in FIG. It did not have a lighting function. Conventional crowns are used only for external operation of the movement, so they do not provide illumination. It does not have functions such as illumination, and movements with illumination functions do not have a dial. Since it only illuminates only the top of the barrel for a very short time, there is no need to press any buttons etc. for this operation. Since it is designed to perform its function only when the There was a drawback that it could not be fulfilled.

0003

[Problem that the idea aims to solve]

Therefore, in order to solve this conventional drawback, this idea was created by adding an illuminated light to the crown head. The purpose of this invention is to solve the above-mentioned drawbacks by providing a bright function.

0004

[Means to solve the problem]

In order to solve the above problem, this invention is designed to In addition to installing a lamp to provide a lighting function, a conductor beam connected to the lamp is also installed. The movement passes through the opening in the center of the crown and is fixed with a ring below the crown. It is designed to make contact with the switch.

[0005]

[Effect]

Pull the crown out to the first position using an external operating member such as the crown configured as above. By pulling it out, the switch part of the movement and the ring provided below the crown will come into contact. External illumination can be created by touching it.

[0006]

【Example】

An embodiment of this invention will be described below based on the drawings. In FIG. 1, the lamp 3 is placed on a step provided at the top of the crown body 1. At the same time, the conductor 3a connected to the lamp is connected to the opening provided in the center of the crown body. 1b, and its tip is located at the center of the crown body, which is provided below the crown body 1. The outer circumference of the shaft of the crown body is inserted into a hole that intersects with the opening 1b passing through the It is arranged so as to be in contact with the fixing ring 5.

[0007] Furthermore, the lamp 3 provided on the upper part of the crown body is protected by a lamp cover 4. At the same time, the crown body is crimped by the stepped tip 1a at the top of the crown. is fixed. Note that the fixing ring 5 provided below the crown has a constant width as shown in Fig. 2. Arranged so that it makes contact with the contact point of switch 6 of the movement when the crown is pushed in. has been done.

[0008] The lamp cover 4 is formed in a spherical shape or a polyhedron along the lamp 3, and is available in various colors. By making it colorful, it can be given decorative properties. The above-mentioned feature can be applied to other external operating members movable in the axial direction instead of the crown body. Of course.

[0009]

[Effect of the idea]

As explained above, this idea places a lamp on the head of the crown, and By installing a lamp cover, light is emitted to the outside, making it easy to illuminate your hands in dark places. It can be used conveniently when the need arises or when walking at night. In addition, you can choose from a wide variety of colors for the lamp cover, giving the crown a precious stone-like appearance. can also be added, which has the effect of increasing fashionability. .
