Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a cufflink locking device.

[Conventional technology]

Conventionally, various types of cufflinks and buttons, such as a chain type, have been sold, but the most commonly used type at present is a combination of a button base, a post, and a clasp. That is, two pillars were provided on the button base, a square shaft was installed between the pillars, and the square shaft was held between the two pillars by a U-shaped spring installed in the clasp, so that the clasp was pivoted between the pillars. It is something. As described above, the clasp of the conventional cufflink button is configured to remain in the same direction or at right angles to the support column and not rotate freely due to the action of the square shaft and the U-shaped spring.

[Problem that the idea aims to solve]

However, when using cufflinks and buttons as described above for shirts, etc., the clasp gets caught on the cuff of a jacket or easily rotates when it comes into contact with other objects, causing the clasp to easily rotate without you noticing. The clasp stands upright in the same direction as the post, and the cufflinks and buttons are aligned with the cufflinks.
It often became detached from the buttonhole and lost. Therefore, in order to solve the above-mentioned problems, this invention improves the clasps of cufflinks and buttons so that they do not easily rotate due to physical phenomena during use, and the clasps do not rotate easily without human operation. To provide a locking device for cufflinks that does not rotate.

[Means to solve the problem]

In order to solve the above problems, the cufflink/button locking device of the present invention is provided with two pillars 7, 7 on a button base 8, and a square shaft 6 installed between the pillars 7, 7 to hold the clasp 1. In cufflinks and buttons that are attached by a shaft, a square hole 2 and a round hole 3 are continuously bored in a clasp 1 to form a shaft hole, and mountain-shaped holes facing each other are formed on the inner surface of a U-shaped spring 5 installed inside the clasp 1. The clasp 1 is made unrotatable by holding the square shaft 6 in the position fitted with the square hole 2 by the protrusions 4, 4.

[Effect]

The present invention configured as described above allows the clasp 1 to be rotated as before with the round hole 3 aligned with the square shaft 6 during attachment and detachment, and when in use.
By fitting the square hole 2 to the square shaft 6, the clasp 1
becomes unrotatable, and the U that holds the square shaft 6 further
This state is maintained by mountain-shaped protrusions 4, 4 facing each other formed on the inner surface of the letter-shaped spring 5.

【Example】

Hereinafter, one embodiment of the present invention shown in the drawings will be explained.
This will be explained in more detail. Reference numeral 1 indicates a clasp in which a square hole 2 and a round hole 3 are continuously bored, and a U-shaped spring 5 is installed inside the spring 5, which has mountain-shaped protrusions 4, 4 formed facing each other on the inner surface.
The square hole 2 is a square hole that fits into the square shaft 6, and the round hole 3 is a round hole having a diameter that allows the clasp 1 to rotate at least about the square shaft 6. Reference numerals 7 and 7 indicate two pillars with a square shaft 6 installed between them, and 8 indicates a button stand. FIG. 1 is a front view showing the clasp 1 in a locked state. In this state, the square hole 2 is fitted into the square shaft 6, so the clasp 1 cannot be rotated. Furthermore, the U-shaped spring 5 holds the square shaft 6, and the mountain-shaped protrusions 4, 4 formed on its inner surface firmly hold the square shaft 6 in this position, so the clasp 1 is more securely locked. state. This figure therefore shows the cufflinks in use. FIG. 2 is a front view showing the state in which the clasp 1 is rotatable. The clasp 1 is slid from the position shown in FIG. 1 by pushing off the pressure from the mountain-like protrusions 4, 4, and the round hole 3 is aligned with the square shaft 6. In this state, the clasp 1 can be rotated like a conventional cuff button, so rotate the clasp 1 in the same direction as the support 7 to make it stand upright. All you have to do is attach/remove the button to the cufflink/button hole.

[Effect of the idea]

The present invention, as described above, simply adds a simple improvement to the structure of the clasp, so that the clasp is securely locked during use, and the clasp rotates naturally and stands upright in the same direction as the pillar, unlike the conventional method. , there is no need to worry about the cufflinks becoming detached from the cufflink button holes and being lost without realizing it. Also, the cufflinks and buttons can be easily attached and detached, just like conventional ones.

Claims (1)

[Scope of utility model registration request] In the cufflink button, the button base 8 is provided with two posts 7, 7, and the clasp 1 is attached to the square shaft 6 installed between the posts 7, 7. The round hole 3 is continuously drilled to form a shaft hole, and the square shaft 6 is fitted into the square hole 2 using mountain-shaped protrusions 4, 4 facing each other formed on the inner surface of a U-shaped spring 5 installed in the clasp 1. A cuff button locking device characterized in that a clasp 1 is made unrotatable by being held in position.
