Description

[Technical field]

[0001] The present invention relates to an eye part, a manufacturing method thereof, and a doll body. [Background technology]

[0002] 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 influencing the expression. Among the face, the eye parts have a particularly large effect on the expression and impression, and the tracking function of the eye parts is also important. For example, Patent Document 1 provides a plate-shaped product with an interesting face drawn on it, which gives the impression that the gaze is directed at the viewer not only when viewed from the front, but also when viewed from above, below, left and right, by a simple and inexpensive method using one and the other sides of a transparent plate-shaped body. In addition, Patent Document 2 proposes a model head having a recess with a pupil drawn on the bottom at the position of the human eye. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility model registration No. 3216743 [Patent Document 2] Patent No. 6198551 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional technology, the face is drawn on the back side of the character product, more specifically, the pupils and the whites of the eyes are drawn on the back side of a transparent acrylic plate, which provides a tracking function. However, in the above-mentioned conventional technology, when the character is viewed at a certain angle from the vertical or horizontal directions, the pupils are simply drawn at the back and cannot be seen. Similarly, even if the pupils are simply drawn on the bottom surface of the recess, they become invisible at a certain angle from the vertical or horizontal directions, and the tracking function is lost.

[0005] In addition, when constructing eye parts by assembling multiple parts, errors in assembly will result in individual differences in the facial expression and impression for each product. Therefore, there is a demand for dolls such as figures that have as few assembled parts as possible and whose facial expression and eye tracking effect are not affected by misalignments or gaps caused by the assembly.

[0006] The present invention provides a mechanism for realizing a wide range of visual tracking function in the eye parts of a doll body with a natural impression, and for suitably manufacturing said function. [Means for solving the problem]

[0007] The present invention is characterized in that, for example, an eye part to be assembled to a facial part of a doll body includes an iris portion disposed on the front surface of the eye part, and a pupil portion having a convex front surface and a protruding portion protruding from the rear surface of the iris portion into the interior of the iris portion. The present invention is also characterized in that, for example, an eye part to be assembled to a facial part of a doll body includes an iris portion disposed on the front surface of the eye part, and a pupil portion having a protruding portion protruding from the rear surface of the iris portion into the interior of the iris portion, and the protruding portion is located deep inside the iris portion without protruding to the surface of the iris portion. The present invention also relates to an eye part to be assembled, for example, to a facial part of a doll body, comprising an iris portion arranged on the front surface of the eye part, and a pupil portion having a protruding portion protruding from a rear surface of the iris portion into the interior of the iris portion, the protruding portion being located deep within the iris portion without protruding to the surface of the iris portion, the iris portion having a concave rear surface.The present invention also relates to an eye part to be assembled, for example, to a facial part of a doll body, comprising an iris portion arranged on the front surface of the eye part, and a pupil portion having a protruding portion protruding from a rear surface of the iris portion into the interior of the iris portion, the iris portion having a concave rear surface.

[0008] The present invention is also a method for manufacturing an eye part to be assembled, for example, to a facial part of a doll body, comprising an iris part molding step of molding an iris part covering the front surface of the eye part, a pupil part molding step of molding a pupil part having a convex front surface and a protruding part protruding from the rear surface of the iris part into the interior of the iris part, and a base part molding step of molding a base part so as to contact the rear surface of the iris part in a portion where the pupil part is not formed. The present invention is also a method for manufacturing an eye part to be assembled, for example, to a facial part of a doll body, comprising an iris part molding step of molding an iris part covering the front surface of the eye part, and a pupil part molding step of molding a pupil part having a protruding part protruding from the rear surface of the iris part into the interior of the iris part, the protruding part being located deep inside the iris part without protruding to the surface of the iris part. The present invention also relates to a method for manufacturing an eye part to be assembled, for example, to a facial part of a doll body, comprising an iris part molding step of molding an iris part covering a front surface of the eye part, and a pupil part molding step of molding a pupil part having a protruding portion protruding from a rear surface of the iris part into the interior of the iris part, the protruding portion being located deep inside the iris part without protruding to the surface of the iris part, and the iris part being formed with a concave rear surface. The present invention also relates to a method for manufacturing an eye part to be assembled, for example, to a facial part of a doll body, comprising an iris part molding step of molding an iris part covering a front surface of the eye part, and a pupil part molding step of molding a pupil part having a protruding portion protruding from a rear surface of the iris part into the interior of the iris part, the iris part being formed with a concave rear surface.

[Diagram 5] 5A to 5C are diagrams illustrating a tracking function and a dividing line of an eye part according to an embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an exemplary embodiment of the present invention will be described with reference to the drawings. In each drawing, the same reference numerals indicate the same elements. In each drawing, the up, down, left and right directions relative to the paper surface will be used in the description in the text as the up, down, left and right directions of the device in this embodiment. In the embodiment described below, the present invention will be exemplified by resin materials of different colors as molding materials, but is not limited to this, and can be applied to molding materials of different materials (thermoplastic resins such as polystyrene, polyethylene, ABS, thermosetting resins, metals, etc.), resins of different transparencies, etc.

[0012] <Facial parts> First, referring to Fig. 1 and Fig. 2, a facial part to be attached to a doll body according to an embodiment of the present invention will be described. The facial part 20 described below is exemplified as a doll body (e.g., a figurine) imitating a human face, but is not limited thereto, and may be any figure having eyes, such as a living thing such as an animal, insect, dinosaur, or fish, or a character having parts corresponding to eyes. In the following, only the facial part will be described among the parts constituting the doll body, and the description of other parts will be omitted, but these parts are not excluded from the configuration of the present invention. In other words, the facial part included in the eye part according to this embodiment constitutes the doll body together with other parts (torso, arms, legs, and optional parts such as weapons).

[0013] The face of the doll body according to this embodiment is formed by assembling eye parts 10 to a facial part 20. Fig. 1(a) shows the front side of the facial part 20, and Fig. 1(b) shows the back side of the facial part 20. Note that the back side of the doll body in this embodiment is covered with hair parts (not shown) and is not exposed to the outside after the figure is completed.

[0014] FIG. 2 shows an exploded perspective view of the eye part 10 and the facial part 20. The eye part 10 is attached to the rear side of the facial part 20, and the parts constituting the left and right eyes, which become part of the eye part 10, are exposed from the hole 20a formed in the facial part 20. In addition, the white of the eye 201 and the eyelashes 202 constituting the eye are formed in advance on the facial part 20 side. Therefore, the eye part 10 attached to the facial part 20 forms the left and right pupil parts, respectively. As a result, the facial part 20 and the eye part 10 are divided into each part with the white of the eye 201 and the pupil as the boundary, for example, the boundary between the white of the eye and the black of the eye (pupil), and the division line can be made less noticeable due to the difference in color. This allows a more natural impression to be maintained. Details of the division line will be described later with reference to FIG. 5. In this embodiment, the terms "white of the eye" and "black of the eye" are used for the sake of convenience, but these terms are used only for the sake of convenience and do not limit the colors of the relevant parts in the present invention. In other words, although the above-mentioned terms are used here, various colors can be used for the white of the eye and the black of the eye depending on the character's design, and colors other than those described here are not excluded. It should be noted that other descriptions of colors used in this specification and claims are similarly not intended to limit the present invention.

[0015] <Side cross section of face and eye parts> Next, a configuration example of the face part 20 to which the eye part 10 according to this embodiment is attached will be described with reference to Fig. 3. Fig. 3 is a side cross section cut in the vertical direction centered on the pupil of the right eye.

[0016] As shown in FIG. 3, the eye part 10 is attached to the hole 20a of the facial part 20 from the back side of the facial part 20. The eye part 10 is configured to include at least an iris part 301, a pupil part 302, and a base part 303. Each part is formed by insert molding and multi-color molding using resin materials of different colors. As shown in FIG. 3, the iris part 301 is formed (placed) so as to cover the front side of the eye part 10, and the pupil part 302 is formed so as to protrude three-dimensionally from a part of the rear side of the iris part 301. The eye part 10 will be described in detail later with reference to FIG. 4 and FIG. 5. On the other hand, the facial part 20 is provided in advance with the white part 201 and the eyelash part 202, which are part of the eye configuration of the doll body, as described above. Therefore, the eye part 10 according to this embodiment constitutes the pupil part other than the white part and the eyelash part that constitute the eye. The iris part 301 may be configured with two or more layers.

[0017] By assembling the eye parts 10 to the facial parts 20, the pupils of the eye parts 10 appear on the surface of the face, forming the facial expression of the doll body. By forming the facial parts 20 and the eye parts 10 separately in this way, for example, the color of the resin material used can be reduced, and the insert molding of each part, which will be described later, can be simplified. Also, by providing multiple types of eye parts, parts with a variety of facial expressions can be easily produced, and a variety of facial expressions can be realized on a single doll body by developing a variety of products and allowing the users to change the eyes.

[0018] <Detailed configuration of eye parts> Next, the detailed configuration of the eye part 10 according to this embodiment will be described with reference to Fig. 4. Fig. 4(a) shows a plan sectional view of the eye part 10, and Fig. 4(b) shows an enlarged view of both eyes of a doll body seen from the front with the eye part 10 attached to the face part 20.

[0019] As described with reference to Fig. 3, the eye component 10 is formed so that the iris portion 301 covers its front surface, and the pupil portion 302 is formed so as to protrude three-dimensionally from a part of the rear surface of the iris portion 301. Furthermore, as shown in Fig. 4(a), at least the protruding portion (tip portion) of the pupil portion 302 is entirely covered by the iris portion 301 and is formed so as not to protrude from the front surface of the iris portion 301. A transparent resin material, for example, a colored transparent resin material such as a blue transparent resin material, is used for the iris portion 301, and a resin material that allows the pupil portion 302 located at the back of the iris portion 301 to be visible is used. On the other hand, a resin material that is darker in color than the iris portion 301, for example, a black or navy blue resin material, is used for the pupil portion 302, and the pupil portion 302 can be clearly confirmed even through the iris portion 301.

[0020] With this configuration, the protruding portion of the pupil portion 302 can be confirmed even when viewed from a certain angle. For example, the pupil can be confirmed to some extent even when viewed from approximately directly to the side of the doll body. In this way, in the eye part 10 according to this embodiment, the pupil can be confirmed from a wide range of angles, and the tracking function described below can be realized with a more natural impression. In addition, since the entire surface of the protruding portion is covered by the iris portion 301, the same impression can be given when viewed from the front and when viewed from above, below, left and right. In other words, since the pupil portion 302 is uniformly covered by the iris portion 301 formed of a transparent resin material, it can be viewed with the same impression over a wide range of angles, and the tracking function can be realized with a more natural impression. On the other hand, for example, if the pupil portion is formed to protrude to the front of the iris portion, although the pupil can be sufficiently confirmed from approximately directly to the side or approximately directly above, it gives an unnatural impression that the pupil is protruding. Therefore, as in this embodiment, arranging the pupil behind the iris portion 301 is important for realizing the tracking function with a natural impression, and for example, a moist texture like that of a human eye can be created. Also, a more natural impression can be achieved by unifying the iris and pupil in similar colors; for example, the iris can be made of a blue transparent resin material and the pupil can be made of a dark blue resin material.

[0021] Although there is no intention to limit the height of the protruding portion protruding into the iris portion 301, it is desirable that the protruding portion is formed so as not to protrude to the surface of the iris portion 301, and basically be visible at the back of the iris portion 301. The optimal height of the protruding portion varies depending on the recess of the eye itself in the facial part 20 and the thickness of the iris portion 301. Also, there is a trade-off between the height of the protruding portion being higher, which increases the range in which the pupil can be confirmed, but also reduces the tracking effect and naturalness. Therefore, it is desirable to form the protruding portion at a height that allows the pupil to be confirmed over as wide a range as possible, while not losing the tracking effect and naturalness, depending on the shape of the peripheral part of the eye on the face.

[0022] The eye part 10 is configured to include a base part 303 in addition to the iris part 301 and the pupil part 302. The base part 303 is formed of a white resin material. Note that, as an example, an example in which the base part 303 is formed of a white resin material will be described here, but this is not intended to limit the present invention. The base part 303 may be formed in a color other than that of the iris part 301 and the pupil part 302, and may be an opaque color. For example, the pupil part 302 may be formed in white and the base part 303 may be formed in black depending on the design of the character realized by the doll body. As shown in FIG. 4(a), the base part 303 is formed so as to contact the rear surface of the iris part 301 at a part different from the part where the pupil part 302 is formed. Also, an uneven shape (including various shapes such as a step shape, a cutting shape such as a diamond cut, a shape formed by an opening and a protrusion, etc.) may be formed on the surface of the base part 303 that contacts the iris part 301. This allows the reflection of light entering the pupil to be dispersed in multiple directions, resulting in a natural pupil brightness. A similar uneven shape may be formed on the rear surface of the iris portion 301 to achieve 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 changes partially, varying the degree of transmission of the base portion 303, and the effect of expressing more complex colors can be expected.

[0023] Also, as shown in FIG. 4(a), the base portion 303 may have a portion adjacent to the iris portion 301 and extending to a position similar to the front surface of the iris portion 301. As shown in the base portion 303 in FIG. 4(b), this portion forms the white portion of the pupil, and can produce light reflection like that of a human eye. As described above, like the base portion 303 that changes according to the character design, the white portion of the pupil may be formed in another color. Also, it does not have to be formed integrally with the base portion 303, and in that case, it may be formed of another resin material of a different color from the base portion 303. On the other hand, when it is formed integrally, the process of insert molding described later can be reduced, and a simpler manufacturing process can be realized.

[0024] (Insert molding procedure) Here, a manufacturing procedure of the insert molding (integral molding) of the eye part 10 according to this embodiment will be described. The eye part 10 is produced by insert molding and multi-color molding using, for example, three colors of resin. Note that the present invention is not limited to the procedure described below.

[0025] In the case of the configuration of each resin material as shown in FIG. 4(a), the pupil portion 302 is primarily molded with, for example, a navy blue resin material for the eye basic part. Then, the base portion 303 is secondarily molded with a white resin material. Finally, the iris portion 301 is tertiarily molded with a blue transparent resin material to obtain the final molded product of the eye part 10. In the above procedure, an example in which a single-color resin material is used in each step has been described, but this is not intended to limit the present invention, and multi-color resin materials may be used. In addition, various colors can be adopted for each resin material depending on the design of the character. In order to maintain the tracking function of the pupil, it is desirable that at least the pupil portion and the base portion are formed with an opaque resin material, and the iris portion is formed with a transparent or semi-transparent resin material.

[0026] As described above, the eye part 10 is molded by repeating insert molding using a plurality of types of resin. This allows the expression of eyes, which has conventionally been provided by printing or stickers, to be easily formed with high accuracy. Furthermore, even in the case of a plastic model in which the user is required to carry out part of the assembly, the process of applying stickers by the user to express the eyes can be eliminated, and a finished product that is satisfactory to the user in a form that does not feel strange can be created even without high skills such as applying stickers or painting. The eye part 10 and the facial part 20 may be molded to have different glosses. For example, the eye part 10 may be molded from a highly transparent resin material such as polystyrene resin, and the facial part 20 may be molded from a resin that is polystyrene resin mixed with rubber or the like to reduce gloss and provide a skin texture.

[0027] <Tracking function and dividing line> Next, the tracking function of the eye part 10 according to this embodiment and the dividing line with the facial part 20 will be described in detail with reference to Fig. 5. Fig. 5(a) shows an enlarged view of the left eye of the doll body, and Fig. 5(b) shows an enlarged view of a horizontal cross section near the pupil part 302.

[0028] (Tracking function) First, the tracking function according to this embodiment will be described. As shown in FIG. 5(b), the tracking function of the eye part 10 according to this embodiment is realized by the iris part 301 and the pupil part 302. The iris part 301 is formed so as to cover the front surface of the eye part 10, and further, the rear surface is formed in a concave shape. This makes the surface below the pupil concave, and the tracking effect can be further improved. Note that, since the tracking effect can also be expected from the protruding portion of the pupil part 302 described later, the rear surface of the iris part 301 may be formed in a flat shape. This makes it possible to realize one step of insert molding in a simpler process.

[0029] As described above, the pupil portion 302 is formed so as to protrude partially near the center of the concave rear surface of the iris portion 301 and to intrude into the iris portion 301. The front surface of the protruding portion is desirably formed in a rounded convex shape. Furthermore, the entire surface of the protruding portion is covered by the iris portion 301. Due to this protruding portion, as shown in FIG. 5(b), when viewed from the front 502, the left 503, or the right 504, the pupil portion 302 is formed behind the iris portion 301, and further, the protruding portion is formed in a rounded convex shape, so that the same impression is given over a wide range. In other words, even when the doll body is viewed while rotating, it is possible to suppress the sense of incongruity that the impression of the pupil portion suddenly changes when viewed from a position beyond a certain angle. In this way, according to this embodiment, the tracking function can be realized over a wide range with a more natural impression.

[0030] (Dividing line) Next, the dividing line between the facial part 20 and the eye part 10 according to this embodiment will be described. As shown in FIG. 5(a), the facial part 20 including the white of the eye 201 and the eyelash part 202 and the eye part 10 including the iris part 301, the pupil part 3021 and the base part 303 are divided along the dashed line 501. Thus, according to this embodiment, when the eye part 10 is inserted into the facial part 20 from the back side and assembled, the dividing line after assembly is formed near the boundary between the white of the eye and the pupil. Generally, the color difference is large near the boundary between the white of the eye and the pupil, and the boundary can be clearly identified. Therefore, forming the dividing line near the boundary has the effect of making the line less noticeable, and it is possible to reduce the sense of incongruity in the facial expression caused by the dividing line due to assembly. It should be noted that the dividing line is not intended to be limited to the dashed line 501 shown in FIG. 5(a), and may be any place as long as it is not noticeable.

[0031] Furthermore, the facial part 20 and eye part 10 according to this embodiment are produced by insert molding and multi-color molding using resins of multiple colors. Therefore, each part, for example, the iris part 301 and the pupil part 302, are molded in close contact with each other, so there are no gaps due to assembly or misalignment due to assembly errors, and the sense of incongruity caused by such assembly can be reduced as much as possible.

[0032] As described above, the eye parts to be attached to the facial parts of the doll body according to this embodiment include an iris part disposed on the front surface of the eye part, and a pupil part having a convex front surface and a protruding part protruding from the rear surface of the iris part into the interior of the iris part. The eye parts according to this embodiment may be configured to form only the pupil part other than the white part and eyelashes that constitute the eye, or may be molded by repeating insert molding. As a result, this embodiment can provide a mechanism for realizing a wide range of tracking function in the eye parts of the doll body with a natural impression, and for suitably manufacturing the same function.

[0033] The present invention is not limited to the above-mentioned embodiment, and various modifications and alterations are possible within the scope of the gist of the invention. For example, the entire surface of the protruding part of the pupil protruding into the iris may be covered by the iris. This makes it possible to realize a tracking function with a natural impression, in which the pupil appears to be located behind the iris in all cases, whether the eye of the doll body is viewed from the front or from above, below, left, or right.

[0034] In addition, an uneven shape may be formed on the front surface of the base portion that contacts the rear surface of the iris portion. Alternatively, an uneven shape may be formed on the rear surface of the iris portion that contacts the front surface of the base portion. This allows the reflection of light entering the pupil portion to be dispersed in multiple directions, reproducing the natural brightness of the human eye. [Explanation of symbols]
