Abstract

Disclosed is a shield for eyelash extension of an eyelash extension system for extending a subject's eyelashes by bonding fake eyelashes thereto. The shield includes a safety cover divided into an upper body and a lower body such that front ends of the upper body and the lower body are paired to be opened or closed together to bite a subject's eyelashes placed therebetween. The safety cover includes a concave curved receiving groove in a front end of the safety cover to accommodate the subject's eyelashes while in contact with a protruding eye of the subject with his or her eye closed, and a work space with an entrance open to a rear side is provided behind the receiving groove. The work space is for accommodating the eyelashes pulled by being bitten between the front ends of the upper and lower bodies and conducting eyelash extension work therein.

First claim

What is claimed is:

1. A shield for eyelash extension of an eyelash extension system for extending a subject's eyelashes by bonding fake eyelashes thereto, the shield comprising a safety cover divided into an upper body and a lower body such that front ends of the upper body and the lower body are paired to be opened or closed together to bite a subject's eyelashes placed therebetween,
wherein the safety cover comprises a concave curved receiving groove in a front end of the safety cover to accommodate the subject's eyelashes while in contact with a protruding eye of the subject with his or her eye closed,
a work space with an entrance open to a rear side is provided behind the receiving groove, the work space for accommodating the eyelashes pulled by being bitten between the front ends of the upper and lower bodies and conducting eyelash extension work therein,
wherein left and right sides of a rear end of the upper body and left and right sides of a rear end of the lower body are hinge-coupled such that the front end of the upper body and the front end of the lower body are paired to be opened or closed together,
wherein the shield further comprises:
an upper lever extending upward from an upper side of the rear end of the upper body; and
a lower lever extending downward from a lower side of the rear end of the lower body,
wherein the front ends of the upper body and the lower body which are normally closed are opened when an external force of a certain level or higher is applied to press the upper lever downward and the lower lever upward,
wherein the shield further comprises:
a support frame installed at a position spaced apart from the rear side of the safety cover, the support frame being formed in a ring shape along the periphery of the entrance of the work space of the safety cover,
wherein supports are provided at a left portion and a right portion of the support frame, the supports being hinge-coupled to a left side and a right side of the rear end of the upper body and a left side and a right side of the rear end of the lower body.

2. The shield of claim 1 , wherein the safety cover is formed such that a vertical width and a horizontal width thereof gradually increase toward the rear end from the front end, and thus a width of the work space of the safety cover gradually increases toward the entrance open to the rear side.

3. The shield of claim 1 , further comprising springs configured to push an upper end of the upper body and a lower end of the lower body forward to close the front ends of the upper body and the lower body, the springs being installed at centers of an upper end and a lower end of the support frame.

4. The shield of claim 1 , wherein the receiving groove has a depth of 13.15 to 15.36 mm, a horizontal width of 32.44 to 36.05 mm, and a vertical width of 32.59 to 36.21 mm.

5. The shield of claim 4 , wherein the front end of the safety cover in which the receiving groove is provided has a radius of curvature of 21 to 22 mm, and
an angle formed by the horizontal width of the front end of the safety cover is 55.72°.

6. The shield of claim 1 , wherein the safety cover is formed of a transparent material.

7. An eyelash extension system for extending a subject's eyelashes by bonding fake eyelashes thereto, the eyelash extension system comprising:
the shield of claim 1 ; and
a heating and bonding device configured to bond the eyelashes and the fake eyelashes by gripping and heating the eyelashes and the fake eyelashes, which are temporarily adhered to each other via an adhesive, by grips inserted via the work space open to the rear side of the safety cover while the eyelashes are bitten by the safety cover of the shield covering the subject's eye.
