BRIEF SUMMARY
DETAILED DESCRIPTION OF THE INVENTION
1. Field of the Invention
The present invention relates to a claspless stud for piercing that is worn by penetrating through an earlobe a shaft having a sharp point at one end and an ornament at the other end.
2. The Prior Art
Pierce-type earrings consist of a shaft that is attached to an earlobe, an ornament provided on the shaft, and a fixture that prevents the earring from slipping out from the earlobe. Among them, earrings for piercing have a shaft with a tip shaped like a sharp needle. Examples of conventional fixtures, which are called clasps or catches, are shown in FIG. 6 in Japanese Utility Model Laid Open No. 63-197412.
The fixture is used with almost all pierce-type earrings, but may obstruct the washing and sterilization that must be performed before a hole penetrating the earlobe is made, resulting in an insanitary condition. In addition, the fixture itself is obstructive and the needle tip for piercing may penetrate the cheek skin.
After the through hole in the earlobe has been completed, a sharp needle is unnecessary, so a pierce-type earring without a needle can then be used instead of the pierce-type earring for piercing. By way of example, a fixture for an earring disclosed in Japanese Utility Model Laid Open No. 3-48507 is shown. The needle-like tip, however, is essential to the earring for piercing, and all known earrings of this type require a member such as a clasp.
SUMMARY OF THE INVENTION
This invention is provided in view of these points, and its object is to enable piercing as with conventional earrings for piercing and to eliminate the need for the needle-like tip and a fixture such as a clasp following piercing.
It is another object of this invention to provide a claspless stud that acts as an earring, can be removed from the earlobe after the through hole has been made, and can later be reinstalled.
These and other objects have been attained by the claspless stud for piercing, which comprises a lock that is larger than the diameter of the shaft is formed at one end of the shaft, and a sharp end piece that is penetrated into the earlobe to form a through hole therein is formed at the tip of the lock so that it can be detached from the shaft.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A claspless stud 10 according to this invention is for piercing and is used to form, in an earlobe without a hole, a through hole through which an earring is worn.
The stud is a shaft 11 having a sharp point A at one end and an ornament 20 at the other end. The shaft 11 is formed of a member shaped like a hollow pipe or a solid rod. The shaft 11 penetrates an earlobe Y. Thus, its length is larger than the thickness of the earlobe Y and its diameter is equal to the inner diameter of a through hole H after it is formed.
A lock 12 that is larger than the diameter of the shaft 11 is formed at one end of the shaft 11. The purpose of the lock 12 is to prevent the shaft 11 from slipping
