AI Technical Summary
Conventional piercing catches are not adaptable to individual differences in earlobe thickness and shape, leading to unstable wearing positions and difficulties in securely holding heavy or peculiarly shaped piercings.
A left-right asymmetric piercing catch with a catch body made of wire, bent into an asymmetrical shape with one side longer, allowing for adjustable support points on the earlobe to enhance stability and holding force.
The asymmetric design allows for flexible accommodation of varying earlobe shapes and sizes, achieving improved stability and aesthetic appeal for piercings, while also improving durability by reducing deformation and breakage.

Abstract
Description
Technical Field
[0001] The present invention relates to a piercing catch used when wearing earrings on the ears.
Background Art
[0002] In recent years, with the popularization of earrings, various shaped piercing catches have been provided. Conventional piercing catches are generally cylindrical parts made of metal or resin, or silicon plug-in catches, which are fixed to the piercing post by pressure or friction.
[0003] However, there are significant individual differences in the thickness and shape of the earlobes. Especially in cases where there are left-right differences or the earlobes are thin / thick, the wearing position of the catch is not stable, which may cause the inclination or dropping of the piercing body.
[0004] In addition, since the "way of supporting" from the back side of the ear cannot be adjusted, there is also a problem that it is difficult to beautifully hold heavy or peculiarly shaped piercings.
[0005] Furthermore, some silicon or metal catches are prone to deterioration, deformation, or breakage during attachment and detachment over time, leaving problems in the wearing feeling and durability.
Summary of the Invention
Problems to be Solved by the Invention
[0006] To accommodate individual differences in earlobes and improve the wearing stability of piercings.
Means for Solving the Problems
[0007] Provided is a piercing catch having a left-right asymmetric structure, and provided is a means capable of wearing piercings stably and beautifully regardless of the shape of the earlobe.
Effects of the Invention
[0008] By flexibly accommodating individual differences in the earlobes and making it easier to maintain the wearing balance of the piercings, it becomes possible to achieve both unprecedented stability and good appearance.

Modes for Carrying Out the Invention
[0010] The present invention is composed of a catch attached to a piercing shaft.
[0011] The catch body made of wire is bent into an asymmetrical shape with one side longer, and a fitting feeling is obtained by shifting the position that supports the earlobe.
[0012] As the constituent material, in addition to precious metals, general metals (e.g., brass, stainless steel), or resin materials such as plastics having appropriate elasticity can also be used.
Examples
[0013] The piercing catch according to an embodiment of the present invention is formed in an asymmetrical curved shape using a long and thin metal wire.
[0014] By making one leg 2 of the catch longer, the support point from the back side of the earlobe is changed, and appropriate holding force and stability can be obtained regardless of the thickness and shape of the wearer's earlobe.
[0015] As the material, in addition to precious metals, brass, stainless steel, or plastic resin having appropriate elasticity can be used.
Explanation of Reference Numerals
[0016] 1 Piercing catch body 2 One leg of the catch
Claims
[Claim 1] This piercing back is made of a wire having a pair of legs and formed with asymmetric lengths, and when the legs of different lengths are attached to a piercing shaft, the support position on the back surface of the wearer's earlobe changes, allowing the piercing to be stably attached regardless of differences in thickness or shape of the earlobe.
