Description

The present invention, artificial eyes, a method for producing a doll and該義eye with a doll head and該義eye having a該義eye.

  As is well known, the artificial eye constituting the doll's eye is a part that greatly affects the expression of the doll, so it can be said to be a particularly important part compared to other parts constituting the doll. Glass eye prosthesis has been highly evaluated as a prosthetic eye that is an important part, and has been used in many dolls.

  The artificial eye made of glass forms white glass into a spherical shape, forms a dent in the sphere, presses and stretches the colored transparent glass in the dent to form an iris, and places the pupil on the iris by placing black glass on the iris. After the formation, it is formed by stacking colorless and transparent glass in a lens shape so as to fill the depression, and it is possible to reproduce the transparency and stereoscopic effect close to human eyes by the unique texture of the glass.

  However, the glass artificial eye is made by hand by the glass craftsman, so it is almost impossible to keep the quality constant. However, there is only a method for producing a plurality of artificial eyes by matching sizes and patterns as much as possible, and selecting a very similar pair from among them, and the production efficiency is very low, so that it is very expensive.

  For this reason, many synthetic resin artificial eyes capable of maintaining a constant quality have been developed as doll artificial eyes instead of glass artificial eyes.

  For example, in Patent Document 1 described later, a doll's eyeball, which is a white colored silicone rubber that forms a white-eye portion, and a transparent eye corresponding to the cornea portion of the eye that covers the white-colored silicone rubber. These silicone rubbers have a Shore A hardness in the range of 1 to 50, and the Shore A hardness of the white colored silicone rubber is smaller than the Shore A hardness of the transparent silicone rubber. An eyeball for a doll is disclosed in which a silicon rubber colored in white and an iris film for forming an iris of the eye are joined between transparent silicon rubber.

  Further, in Patent Document 2 mentioned later, an iris middle piece is formed in an empty room formed by combining a circular white base piece made of synthetic resin such as vinyl chloride and a dome-shaped transparent covering piece made of synthetic resin such as vinyl chloride. A decorative eye that is fixed and encapsulated, and the iris middle piece forms an inverted conical surface continuously with the inner peripheral edge of the annular rising portion formed in the peripheral portion, and a small circle in the center of the inverted conical surface An embossing process is applied to a part other than the part to arrange unevenness radially, and a black circular colored part is formed on the lower surface of the small circular part with a paint or the like.

Further, in Patent Document 3 listed below, short fiber groups are implanted on the outer peripheral side of a dome-shaped transparent covering piece made of a transparent dome and the outer peripheral side of a dome-shaped transparent middle piece having a colored portion made of a transparent dome, and on the lower surface. A decorative dome formed by fixing and sealing a dome-shaped transparent middle piece in an empty space formed by bonding the circular opaque base piece and the dome-shaped transparent cover piece. A decorative eye is disclosed in which a circular colored portion having a color different from that of the colored portion is provided in the center of the colored portion of the dome-shaped transparent middle piece, and a plurality of fine lines are provided radially around the colored portion. ing.

  However, in the eyeball for a doll disclosed in Patent Document 1, the pupil is expressed by flatly attaching an iris film such as paper or synthetic resin film on which an iris is drawn or printed. When the user's eyeball is viewed, there is a problem that the three-dimensional effect like a human eye cannot be reproduced in the pupil.

  Further, in the decorative eyes disclosed in Patent Documents 2 and 3, the pupil is expressed by an iris middle piece (dome-shaped transparent middle piece) in which an iris is drawn on a conical concave or dome-shaped plate. Since the dome-shaped transparent covering covering the iris middle piece is not formed in a lens shape, when looking at the eyeball for such a doll, there is a problem that the three-dimensional feeling like a human eye cannot be reproduced in the pupil there were.

Therefore, the present invention aims at realizing the technical eye to obtain a prosthetic eye that can reproduce the transparency and stereoscopic effect of the human eye and can maintain a constant quality even in mass production. As a result of repeating trial manufacture and experiment, a main body having a dome surface on the front side, a decorative body fitted in a recess formed on the dome surface of the main body, and a biconvex lens-like lens fitted in a recess formed on the front surface of the decorative body In a prosthetic eye with a body and a pupil formed by coloring the inner surface of a hollow formed at the center of the rear surface of the lens body, the decorative body is formed by changing the thickness in the front-rear direction with a colored transparent material In this way, we obtained the remarkable knowledge that the color and shade of the decorative body can change according to the thickness and mechanically reproduce the translucency and stereoscopic effect of the human eye, achieving the above technical problem. What .

  The technical problem can be solved by the present invention as follows.

  Further, according to the present invention, in the artificial eye, a part or the whole of the decorative body is formed by continuously changing the thickness, and the shade of the color of the part or the whole changes in a gradation according to the thickness. It is what.

  In the present invention, the decorative body is formed by changing the thickness concentrically in any one of the above artificial eyes.

  In any one of the above artificial eyes, the present invention is such that a colored layer is formed on the joint surface between the concave portion of the main body and the decorative body.

Moreover, the head and doll of the doll which concern on this invention are equipped with one of the said artificial eyes.

  In addition, the method for manufacturing an artificial eye according to the present invention includes a main body having a dome surface on the front side, a decorative body fitted in a recess formed in the dome surface of the main body, and a recess fitted in a front surface of the decorative body. A method for manufacturing a prosthetic eye comprising a convex lens-shaped lens body and a pupil positioned at the center of the rear surface of the lens body, wherein the concave portion of the main body is filled with an adhesive and then the concave portion is filled with the concave portion in advance. A step of fitting a decorative body soaked in the same adhesive, and a step of fitting a lens body immersed in the same adhesive as the adhesive that previously filled the concave portion in the recess formed on the front surface of the decorative body. is there.

  According to the present invention, since the decorative body is formed so as to change the thickness in the front-rear direction by the colored material having transparency, the color shade of the decorative body changes according to the thickness, and thereby the lens body In combination with this lens effect, it is possible to reproduce the transparency and stereoscopic effect of the human eye. Moreover, since the decorative body can be mechanically mass-produced with the same shape by a mold or the like, the pupil pattern of the artificial eye can be kept constant, and the quality can be kept constant.
