Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an earring fastener, and more particularly to a fastener that can adjust the strength of the clamping force of a clip-on earring against an earlobe.

[Conventional technology]

Earrings are usually worn by making a hole in the earlobe to support them, or by fastening them to the ear using clips or screws. However, as shown in FIG. 4, the clip-on earring clasp is inserted from one end into each shaft hole 4 of the armrest 3 bent on both sides of the rising bracket 2 provided on the base plate 1. A pivot 8 is formed on both sides of the above-mentioned one end of the spring plate 7, which has a protruding bullet piece 6 in the middle by cutting two slits 5 on the left and right sides.
In this assembled state, the protrusion of the bracket 2 is attached to the inner surface of the bracket 2 so that the tip of the bullet 6, which protrudes outward from the position where the pivot shaft 8 is formed, pushes the inner surface upward. 2' are brought into contact with each other.

[Problem that the invention attempts to solve]

In the fastener having the above structure, the earrings are worn by rotating the spring plate 7 about the pivot 8 in the direction of the bold arrow and sandwiching the earlobe between the spring plate and the base plate 1. However, the clamping force between the substrate 1 and the spring plate 7 becomes maximum at the position just before the spring plate is rotated and the tip of the bullet piece 6 is raised highest by the protrusion 2'.

By the way, in the conventional stopper mentioned above, the height of the protrusion 2' that contacts the bullet 6 is constant, so the clamping force cannot be adjusted to be strong or weak.On the other hand, it depends on the thickness of the earlobe. There are not only individual differences, but also individual preferences regarding the degree of the above-mentioned clamping force, and furthermore, there are differences in the weight of the earrings due to the ornaments. Therefore, if the clamping force is too strong from the beginning, it will cause pain in the ear, whereas if it is weak, the earrings will fall off.
Manufacturers have to manufacture various products with different clamping forces.

The present invention has been developed to address this situation, and allows the gripping force on the earlobe to be adjusted at any time by simply vertically adjusting the height of the protrusion of the spring plate on the side of the bracket that the bullet comes into contact with. It is.

[Means for solving problems]

The stop of the present invention has two left and right slits cut from one end into the armholes of the armrests provided on both sides of the upper part of the bracket, so that the left and right pivots of the spring plate with a spring piece formed in the center can be adjusted. In the configuration in which the spring plate is assembled between the armrests by inserting the spring plate, a slide piece is provided at one end with a receiving portion that protrudes outward from the position where the pivot of the elastic piece is formed and comes into contact with the inner surface of the spring plate. A frame provided on the bracket holds the receiving part in a vertically movable manner so that the receiving part can be moved forward and backward relative to the bullet piece, and the tip of a set screw screwed into the bracket is formed at the other end of the slide piece. It is characterized by being brought into contact with a surface.

[Effect]

The fastener of the present invention attaches the earrings by rotating the spring plate around the pivot and sandwiching the earlobe between the spring plate and the base plate, and the clamping force on the earlobe is as follows:
The strength can be adjusted by moving the slide piece up and down with respect to the bullet contact part, and when according to the present invention, the inclined surface provided on the slide piece can be adjusted by rotating the set screw screwed into the bracket. When pressed, the slide piece moves in the direction of raising the bullet piece, increasing the clamping force of the spring plate.On the other hand, when the set screw is loosened, the slide piece moves back and weakens the clamping force. be.

〔Example〕

Hereinafter, the present invention will be explained with reference to the embodiments shown in the drawings. In Figs. 1 to 3, reference numeral 11 denotes a bracket formed to rise inward from a base plate 12 to which a decorative body (not shown) is attached. Inwardly bent armrests 13 are formed oppositely on both sides, and a shaft hole 14 is provided in the sleeves. In the case of a type in which the substrate 12 also serves as a support frame for the decoration, the substrate 12 may be omitted and the bracket 11 may be directly mounted on this support frame.
Reference numeral 15 denotes a spring plate having an appropriately shaped shape, and one end has two slits 16, 16 extending toward the inside.
By cutting, an elongated elastic piece 17 is formed in the center, and pivots 18 are provided on both sides of the one end of the spring plate, and the pivots are inserted into the respective shaft holes 14. Possibly spring plate 15
is rotatably attached to the armrests 13, 13 of the bracket 11. Although the bullet piece 17 is shown in the figure as a straight plate, it may be slightly curved so that it can be warped either up or down.

Reference numeral 19 denotes a slide piece having a receiving portion 19a at its upper outer end that abuts the inner surface near the tip of the elastic piece 17 that protrudes outward from the position where the pivot 18 is formed in the spring plate 15; Bracket 1 with 19a protruding toward the side of bullet 17.
It is slidably held by a frame 20 provided along the forming surface of 1 so that it can move forward and backward in the vertical direction.
Reference numeral 21 designates the inner end of the slide piece 19, and is a set screw screwed through the bracket 11 so that the outer periphery of the tip slides on the inclined surface 19b formed on the side facing the surface of the bracket 11.

In the above configuration, in the assembled state shown in FIG. 1, the spring plate 15 is rotated about the pivot shaft 18 so as to be separated from the base plate 12 in the direction of the arrow A, and the earlobe is placed between the spring plate and the base plate. At this time, since the bullet piece 17 is in contact with the receiving portion 19a of the slide piece 19, the bullet piece is raised against the spring plate 15, and the spring plate 1
5 to apply a clamping force in the direction of the arrow A. Next, when you want to strengthen this clamping force, tighten the set screw 21 appropriately. As shown in FIGS. 3A and 3B, the inclined surface 19b of the slide piece 19 is pushed up and the slide As the piece moves in the direction of the arrow B, the bullet piece 17 rises higher than in the case described above, and the above-mentioned clamping force by the spring plate 15 is strengthened.On the contrary, when the slide piece 19 is lowered, it becomes weaker. be.

Note that the tip of the set screw 21 is connected to the slide piece 19.
The upper end of the receiving portion 1 is in contact with the lower end inclined surface 19b of the
Since the bullet 9a is constantly pressed from above by the bullet 17, it will not come loose accidentally.

[Effect of idea]

According to the present invention, the clamping force of the spring plate can be changed by adjusting the set screw, so the user can adjust the clamping force by the spring plate, taking into account the size and thickness of the earlobes, individual differences in clamping strength, and the overall weight of the earrings. This makes it possible to freely adjust the product according to the user's preference, which not only benefits the user but also allows the manufacturer to mass produce uniform products. It is easy to handle because it is moisturized, and the set screw does not loosen during use.
