JP7157120B2 - Eye part, manufacturing method thereof, and doll body - Google Patents

Description

TECHNICAL FIELD The present invention relates to an eye component, a manufacturing method thereof, and a doll body.

The facial expression of a doll body such as a figure is a very important part in determining the value of the figure as well as affecting its expression. Among the parts of the face, the eye parts have a particularly large effect on facial expressions and impressions, and the tracking function of the eye parts is also important. For example, in Patent Document 1, a simple and inexpensive method using one surface and the other surface of a transparent plate-like body is used, not only when the face is viewed from the front, but also when the face is viewed from the top, bottom, left, and right. There are plate-shaped products with interesting faces drawn on them that give the impression that your eyes are directed at what you are looking at. Further, Japanese Patent Laid-Open No. 2002-200003 proposes a model head having a concave portion with a pupil portion drawn on the bottom surface at the position of human eyes.

Utility Model Registration No. 3216743 Patent No. 6198551

In the prior art described above, the face is drawn on the back side of the character product, and more specifically, the pupils and whites of the eyes are drawn on the back side of a transparent acrylic plate, thereby providing a follow-up function. However, in the above conventional technology, when the character is viewed from a position with a certain angle from the vertical or horizontal direction, the eyes are simply drawn in the back and cannot be seen. Similarly, even if the pupil is simply drawn on the bottom surface of the concave portion, the pupil becomes invisible at a certain angle from the vertical or horizontal direction, and the tracking function is lost.

In addition, when a plurality of parts are assembled to constitute an eye part, errors in assembling them cause individual differences in facial expressions and impressions for each product. Therefore, there is a demand for a doll body such as a figure that has as few assembly parts as possible and does not affect facial expressions and follow-up effects according to misalignments and gaps due to assembly.

The present invention provides a mechanism that realizes a wide range of tracking function in the eye parts of a doll body with a natural impression, and that can suitably manufacture the same function.

The present invention provides, for example, an eye component to be attached to a facial component of a doll body, comprising an iris portion arranged on the front surface of the eye component, a convex front surface, and a rear surface of the iris portion. and a pupil portion having a projecting portion projecting from and projecting into the iris portion.
Further, the present invention provides, for example, an eye component to be attached to a facial component of a doll body, the eye component having an iris portion disposed on the front surface of the eye component, a convex front surface, and the iris portion having a convex shape. a pupil portion having a projecting portion projecting from the rear of the pupil portion and projecting into the iris portion, the iris portion having a bottom surface different from the projecting portion formed in a concave shape, and the projecting portion It is characterized by being positioned deep inside the iris without protruding to the surface of the iris.

The present invention also provides, for example, a method for manufacturing an eye part to be assembled to a face part of a doll body, comprising: an iris part forming step of forming an iris part covering the front surface of the eye part; and forming a pupil portion having a projecting portion projecting from the rear surface of the iris portion and projecting into the iris portion; and a base part forming step of forming the base part so as to be in contact with the rear surface of the base part.

Exemplary embodiments of the invention will now be described with reference to the drawings. In each figure, the same reference numerals denote the same elements. Also, in each drawing, the up, down, left, and right directions with respect to the paper surface are used as the up, down, left, and right directions of the apparatus in this embodiment in the description of the text. In the embodiments described below, the present invention exemplifies resin materials of different colors as molding materials, but is not limited thereto. It can also be applied to molding materials such as metals, etc.) and resins with different degrees of transparency.

<Facial parts>
First, with reference to FIGS. 1 and 2, a facial component to be attached to a doll body according to one embodiment of the present invention will be described. The facial part 20 described below exemplifies a doll body (for example, a figure) that imitates a human face, but is not limited to this. It may be a creature such as a fish, or a figurative object such as a character having a portion corresponding to an eye. Of the parts constituting the doll body, only the facial parts will be explained below, and explanations of the other parts will be omitted, but these parts are not excluded from the configuration of the present invention. In other words, the face part included in the eye part according to this embodiment constitutes the doll body together with other parts (body, arms, legs, and optional parts such as weapons).

The face of the doll body according to this embodiment is formed by assembling the eye part 10 to the facial part 20 . 1(a) shows the front side of the facial component 20, and FIG. 1(b) shows the back side of the facial component 20. FIG. The back side of the doll body in this embodiment is covered with a hair part (not shown) or the like, so that it is not exposed to the outside after the figure is completed.

FIG. 2 shows an exploded perspective view in which the eye component 10 and the facial component 20 are exploded. The eye component 10 is assembled from the back side of the facial component 20, and portions forming the left and right eyes, which are part of the eye component 10, are exposed from the holes 20a formed in the facial component 20.例文帳に追加Further, on the facial component 20 side, the white portion 201 and the eyelash portion 202 that constitute the eyes are formed in advance. Accordingly, the eye part 10 assembled to the facial part 20 forms left and right pupil portions, respectively. As a result, the facial part 20 and the eye part 10 are divided into respective parts with the white part of the eye 201 and the pupil as boundaries, for example, the division is made at the boundary between the white part of the eye and the black part of the eye (pupil). , the division line can be made less conspicuous due to the difference in color. This makes it possible to maintain a more natural impression. Details of the dividing line will be described later with reference to FIG. In this embodiment, the terms “white part of the eye” and “black part of the eye” are used for explanation, but these terms are used only for convenience of explanation, and limit the color of the corresponding part in the present invention. I am not. In other words, although the terms as described above are used here, various colors can be adopted for the white portion and black portion of the eye depending on the design of the character, and colors other than those described here are not excluded. It should be noted that other statements regarding color used in this specification and claims are likewise not intended to limit the present invention.

<Side cross section of facial parts and eye parts>
Next, with reference to FIG. 3, a configuration example will be described using a side sectional view of the facial component 20 to which the eye component 10 according to the present embodiment is assembled. FIG. 3 is a side cross-section cut vertically about the pupil of the right eye.

As shown in FIG. 3, the eye component 10 is assembled into the hole 20a of the facial component 20 from the back side of the facial component 20. As shown in FIG. The eye component 10 includes at least an iris portion 301 , a pupil portion 302 and a base portion 303 . Each part is formed by insert molding and multicolor molding using resin materials of different colors. As shown in FIG. 3 , an iris portion 301 is formed (arranged) so as to cover the front surface of the eye component 10 , and a pupil portion 302 is formed so as to three-dimensionally protrude from a part of the rear surface of the iris portion 301 . ing. A detailed description of the eye part 10 will be given later with reference to FIGS. 4 and 5. FIG. On the other hand, as described above, the facial part 20 is provided in advance with the white portion of the eye 201 and the eyelash portion 202, which are part of the eye structure of the doll body. Therefore, the eye component 10 according to the present embodiment constitutes a pupil portion other than the white portion of the eye and the eyelashes. Note that the iris portion 301 may be composed of two or more layers.

By assembling the eye part 10 to the face part 20, the pupil portion formed by the eye part 10 appears on the face, and the facial expression of the doll body is formed. By separately forming the facial component 20 and the eye component 10 in this manner, for example, the color of the resin material used can be reduced, so that the insert molding of each component, which will be described later, can be simplified. In addition, by providing a plurality of types of eye parts, it is possible to easily produce parts with various facial expressions, develop various products, and realize various facial expressions in one doll body by allowing users to replace the parts. can also

<Detailed configuration of eye parts>
Next, with reference to FIG. 4, the detailed configuration of the eye component 10 according to this embodiment will be described. FIG. 4(a) shows a plan cross-sectional view of the eye part 10, and FIG. 4(b) shows an enlarged view of both eyes of the doll body when the eye part 10 is attached to the face part 20, viewed from the front. .

As described with reference to FIG. 3 , the eye component 10 is formed so that the front surface thereof is covered with the iris portion 301 , and the pupil portion 302 protrudes three-dimensionally from a part of the rear surface of the iris portion 301 . formed. Further, at least the protruding portion (tip portion) of the pupil portion 302 is entirely covered with the iris portion 301 as shown in FIG. . For the iris portion 301, a transparent resin material, for example, a colored transparent resin material such as a blue transparent resin material is used. On the other hand, the pupil portion 302 is made of a darker resin material than the iris portion 301, such as a black or dark blue resin material, so that the pupil portion 302 can be clearly seen through the iris portion 301 as well.

With such a configuration, the projecting portion of the pupil portion 302 can be confirmed even when viewed from a certain angle. For example, even when the doll body is viewed almost from the side, the pupils can be confirmed to some extent. As described above, in the eye component 10 according to the present embodiment, the pupil can be confirmed from a wide range of angles, and the follow-up function, which will be described later, can be realized with a more natural impression. In addition, since the entire surface of the projecting portion is covered with the iris portion 301, the same impression can be given when viewed from the front and when viewed from the top, bottom, left, and right. In other words, the pupil portion 302 is uniformly covered with the iris portion 301 made of a transparent resin material, so that it can be visually recognized with the same impression over a wide range of angles, realizing a tracking function with a more natural impression. can do. On the other hand, for example, when the pupil is formed so as to protrude to the front of the iris, the pupil can be sufficiently confirmed from almost directly beside or almost directly above, but it gives an unnatural impression that the pupil protrudes. . Therefore, placing the pupil behind the iris portion 301 as in the present embodiment is important for realizing the tracking function with a natural impression. be able to. In addition, if the iris and pupil are made of the same color, a more natural impression can be obtained.

Although there is no intention to limit the height of the protruding portion protruding into the iris portion 301, the protruding portion should be formed so as not to protrude at least to the surface of the iris portion 301, and basically the protruding portion can be seen at the back of the iris portion 301. degree is desirable. The optimal height of the protruding portion varies depending on the recess of the eye itself in the facial component 20 and the thickness of the iris portion 301 . In addition, there is a trade-off relationship in that the higher the height of the projecting portion, the wider the range in which the pupil can be confirmed, but the loss of the tracking effect and naturalness. Therefore, it is desirable to form the protruding portion at a height that allows the pupil to be confirmed as widely as possible and does not lose the tracking effect and naturalness, depending on the shape of the peripheral portion of the eye on the face.

Further, the eye component 10 includes the base portion 303 in addition to the iris portion 301 and the pupil portion 302 . The base portion 303 is made of a white resin material. Here, as an example, an example in which the base portion 303 is formed of a white resin material will be described, but there is no intention to limit the present invention. The base portion 303 may be formed of other colors according to the colors of the iris portion 301 and the pupil portion 302, and may be any opaque color. For example, the pupil part 302 may be formed in white and the base part 303 may be formed in black according to the design of a character realized as a doll body. As shown in FIG. 4A, the base portion 303 is formed so as to contact the rear surface of the iris portion 301 at a portion different from the portion where the pupil portion 302 is formed. Further, the surface of the base portion 303 that contacts the iris portion 301 may be formed with an uneven shape (including various shapes such as a stepped shape, a cutting shape such as a diamond cut, and a shape formed by an opening and a protrusion). . This makes it possible to disperse the reflection of the light incident on the pupil portion in multiple directions, and express the natural brilliance of the pupil. A similar uneven shape may be formed on the rear surface of the iris portion 301 so as to obtain the same effect. By forming an uneven shape on the rear surface of the iris portion 301, the film thickness of the iris portion 301 is partially changed, the degree of transmission of the underlying portion 303 is varied, and an effect of expressing more complicated colors can be expected. .

Further, as shown in FIG. 4A, the base portion 303 may have a portion adjacent to the iris portion 301 and extending to the same position as the front surface of the iris portion 301 . This portion forms the white portion of the pupil, as shown in the base portion 303 in FIG. 4B, and can produce light reflection similar to that of the human eye. As described above, the white portion of the pupil may be formed in other colors, as well as the base portion 303, which changes according to the design of the character. Moreover, it may not be formed integrally with the base portion 303 , and in that case, it may be formed of a different resin material with a color different from that of the base portion 303 . On the other hand, when it is integrally formed, it is possible to reduce the step of insert molding, which will be described later, and to realize a simpler manufacturing process.

(Insert molding procedure)
Here, a manufacturing procedure for insert molding (integral molding) of the ocular component 10 according to the present embodiment will be described. The eye part 10 is produced by, for example, insert molding and multicolor molding using resins of three colors. In addition, there is no intention which limits this invention to the procedure demonstrated below.

In the configuration of each resin material as shown in FIG. 4A, the pupil portion 302 is primarily molded with, for example, a dark blue resin material for the eye base part. Subsequently, the base portion 303 is secondarily molded with a white resin material. Finally, the iris part 301 is three-dimensionally molded with a blue transparent resin material to obtain the final molded product of the eye component 10 . In the above procedure, an example of using a single-color resin material in each step has been described, but there is no intention to limit the present invention, and multi-color resin materials may be used. Also, various colors can be adopted for the colors of the respective resin materials according to the design of the character. In order to maintain the tracking function of the pupil, it is desirable that at least the pupil and base are made of an opaque resin material, and the iris is made of a transparent or translucent resin material.

As described above, the eye component 10 is molded by repeating insert molding using a plurality of types of resin. As a result, it is possible to easily form, with high accuracy, an expression of the eye that has conventionally been provided by means of printing or stickers. Furthermore, even in the case where the user is allowed to partially assemble the model like a plastic model, it is possible to eliminate the user's step of attaching stickers to represent the eyes, and even if the user does not have advanced skills such as sticker attachment and painting, the user can It is possible to create a satisfactory finished product in a form that does not cause any discomfort to the customer. Note that the eye part 10 and the facial part 20 may be molded to have different lusters. For example, the eye component 10 may be molded from a highly transparent resin material such as polystyrene resin, and the facial component 20 may be molded from polystyrene resin mixed with rubber or the like to reduce luster and give a skin texture. good.

<Follow-up function and division line>
Next, with reference to FIG. 5, the division line between the tracking function of the eye component 10 and the facial component 20 according to this embodiment will be described in detail. FIG. 5(a) shows an enlarged view of the left eye of the doll body, and FIG. 5(b) shows an enlarged plan view of the vicinity of the pupil portion 302. FIG.

(tracking function)
First, the tracking function according to this embodiment will be described. As shown in FIG. 5B, the tracking function of the eye component 10 according to this embodiment is achieved by an iris portion 301 and a pupil portion 302 . The iris portion 301 is formed to cover the front surface of the eye component 10 and has a concave rear surface. As a result, the area below the pupil becomes concave on one side, and the tracking effect can be further enhanced. Note that the rear surface of the iris portion 301 may have a flat shape because a tracking effect can also be expected from the projecting portion of the pupil portion 302, which will be described later. As a result, one step in insert molding can be realized by a simpler step.

Further, as described above, the pupil portion 302 is formed so as to partially protrude near the center of the concave rear surface of the iris portion 301 and enter the inside of the iris portion 301 . It is desirable that the front surface of the projecting portion is formed in a rounded convex shape. Furthermore, the entire surface of the projecting portion is covered with the iris portion 301 . As shown in FIG. 5B, this projecting portion forms the pupil portion 302 behind the iris portion 301 when viewed from the front 502, or when viewed from the left 503 or right 504. Furthermore, since the projecting portion is formed in a rounded convex shape, the same impression is given over a wide range. That is, even if the doll body is viewed while rotating, it is possible to suppress discomfort such as sudden changes in the impression of the pupil when viewed from a position exceeding a predetermined angle. Thus, according to the present embodiment, the tracking function can be realized over a wide range with a more natural impression.

(dividing line)
Next, the dividing line between the facial component 20 and the eye component 10 according to this embodiment will be described. As shown in FIG. 5A, the facial component 20 including the white portion of the eye 201 and the eyelash portion 202 and the eye component 10 including the iris portion 301, the pupil portion 3021 and the base portion 303 are separated along the dashed line 501. divided by As described above, according to the present embodiment, when the eye component 10 is inserted into the face component 20 from the back surface and assembled, the dividing line after assembly is formed near the boundary between the white part of the eye and the pupil part. . In general, there is a large color difference near the boundary between the white of the eye and the pupil, and the boundary can be clearly identified. Therefore, by forming the division line near the boundary, there is an effect of making the line inconspicuous, and it is possible to reduce the discomfort of the division line due to assembly. As for the division line, there is no intention to limit the present invention to the one-dot chain line 501 shown in FIG.

Also, the facial component 20 and the eye component 10 according to this embodiment are produced by insert molding and multicolor molding using resins of multiple colors. Therefore, since each part of each part, such as the iris part 301 and the pupil part 302, is molded in close contact with each other, there is no gap due to assembly or misalignment due to assembly error.

As described above, the eye part to be attached to the face part of the doll body according to the present embodiment includes the iris part arranged in front of the eye part, the front surface having a convex shape, and the iris part. a pupil having a protruding portion protruding from the rear surface and protruding into the iris. Further, the eye component according to the present embodiment may be configured so as to form only the pupil portion other than the white portion of the eye and the eyelash portion, or may be formed by repeating insert molding. . As a result, according to the present embodiment, it is possible to realize a wide range of tracking function in the eye parts of the doll body with a natural impression, and to provide a mechanism capable of suitably manufacturing the same function.

The present invention is not limited to the above-described embodiments, and various modifications and changes are possible within the scope of the gist of the invention. For example, the entire surface of the protruding portion of the pupil protruding into the iris may be covered with the iris. As a result, the pupil appears to be located behind the iris regardless of whether the doll's eye is viewed from the front or from the top, bottom, left, or right, and the follow-up function gives a natural impression. can be realized.

Also, the front surface of the base portion, which is in contact with the rear surface of the iris portion, may be formed with an uneven shape. Alternatively, an uneven shape may be formed on the rear surface of the iris portion that contacts the front surface of the base portion. As a result, reflection of light incident on the pupil can be dispersed in multiple directions, and natural brilliance similar to that of the human eye can be reproduced.
