Description

[Technical Field]

[0001] The present invention relates to a doll head prosthetic eye holding structure and a doll head. [Background technology]

[0002] There are dolls that can be customized to suit individual preferences by combining multiple parts. For example, Patent Document 1 discloses a doll head in which the prosthetic eye component can be replaced with a custom one. This doll head includes a head body, a spherical prosthetic eye component, and a pressing mechanism that presses and holds the prosthetic eye component against the inner surface of the head body. The holding surface of the pressing mechanism that holds the prosthetic eye component is formed into a concave curved surface that matches the shape of the prosthetic eye component. This structure allows the prosthetic eye component to be replaced, and also makes it easy to adjust the orientation of the prosthetic eye component (specifically, the iris attached to the prosthetic eye component), which is an important element in determining facial expressions, by rotating the prosthetic eye component along the concave curved surface.

[0003] In recent years, this type of doll head has become available in a lineup of not only prosthetic eye components but also the head itself, allowing for more detailed customization of facial expressions.

[0004] However, if you want to offer a lineup of head bodies with different eye positions, for example, the doll head described in Patent Document 1 poses a problem. Specifically, with the doll head described in Patent Document 1, the prosthetic eye component is positioned on the head body by fitting into a concave curved surface. Therefore, if the eye position of the head body changes, the orientation and position of the pressing mechanism must be readjusted to match the new position. As a result, the internal structure must be modified for each head body, which increases manufacturing costs. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 4182510 Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, the main objective of the present invention is to provide an artificial eye holding structure that not only allows the orientation of the artificial eye component to be easily adjusted, but can also be used even if the position of the eye on the head body is different. [Means for solving the problem]

[0007] The artificial eye holding structure for a doll's head according to the present invention comprises a hollow head body with through holes formed at the positions of the eyes, and holds an artificial eye member within the head body so that it can be seen from the outside through the through holes.The artificial eye holding structure for a doll's head further comprises an artificial eye holding body that is provided within the head body and has a holding surface that contacts the back surface of the artificial eye member facing in the opposite direction to the surface that can be seen from the outside through the through holes, and holds the artificial eye member by sandwiching it between the holding surface and the inner surface of the head body, and is characterized in that the holding surface is convex.

[0008] With this configuration, the holding surface of the artificial eye holder is convex, so the orientation of the artificial eye member can be easily changed by rotating it along the holding surface without moving it relative to the holding surface. Furthermore, by moving the artificial eye member relative to the holding surface, it is possible to align it with the through-hole even if the position of the eye in the head body changes. As a result, the same artificial eye holding structure can be used for head bodies with different eye positions, reducing manufacturing costs.

[0009] The contact surface may also be a convex spherical surface or an ellipsoidal spherical surface.

[0010] With this configuration, the position of the eyes on the head body can be aligned with the through-holes regardless of whether the position is changed in the left, right, up, or down direction.

[0011] The artificial eye holder may also be elastically deformable.

[0012] With this configuration, the artificial eye component is pressed against the inner surface of the head body by the restoring force of the artificial eye holder, making it less likely to come off accidentally.

[0013] In addition, the head body may be configured to be separable into a face member that constitutes the face side and a head member that constitutes the head side, and the artificial eye holder may be arranged to rise from the inner surface of the face member on the neck side rather than the through hole.

[0014] With this configuration, by removing the head component, it is possible to access the interior of the face component from the head side. This allows the prosthetic eye component to be replaced or its orientation to be changed while the doll's head is still attached to the body. Furthermore, since the prosthetic eye holder is arranged to rise from the inner surface of the face component on the neck side of the through-hole, the holding space between the holding surface and the inner surface of the head body is opened toward the head side. This allows the prosthetic eye component to be inserted and removed from the holding space from the head side of the face component, making replacement easy. Furthermore, the orientation of the prosthetic eye component held in the holding space can be easily changed.

[0015] In addition, the head body may have a through hole formed at the position of each of the left and right eyes, and the holding surfaces corresponding to each of the through holes may all be formed on a single artificial eye holder.

[0016] With this configuration, the holding surfaces corresponding to each through hole are formed on one artificial eye holding body, thereby reducing the number of parts and keeping manufacturing costs down.

[0017] In addition, the artificial eye holding structure for a doll head according to the present invention comprises a hollow head body with through holes formed at the positions of the eyes, and holds an artificial eye member within the head body so that it can be seen from the outside through the through holes.The artificial eye holding structure further comprises an artificial eye holding body that is provided within the head body and has a holding surface that contacts the back surface of the artificial eye member facing in the opposite direction to the surface that is visible from the outside through the through hole, and holds the artificial eye member by sandwiching it between the holding surface and the inner surface of the head body, and the holding surface is convex when the back surface is flat, and is convex or flat when the back surface is convex.

[0018] In addition, the doll head of the present invention comprises a hollow head body with through holes formed at the positions of the eyes, a prosthetic eye member held within the head body so that it can be seen from the outside through the through holes, and a prosthetic eye holder that is provided within the head body and has a holding surface that contacts the back surface of the prosthetic eye member facing in the opposite direction to the surface that can be seen from the outside through the through hole, and holds the prosthetic eye member by sandwiching it between the holding surface and the inner surface of the head body, and the holding surface is convex when the back surface is flat, and is convex or flat when the back surface is convex.

[0019] With this configuration, the holding surface of the artificial eye holder is convex when the back surface of the artificial eye member is flat, and convex or flat when the back surface is convex. Therefore, the orientation of the artificial eye member can be easily changed by rotating it without moving it relative to the holding surface. Furthermore, by moving the artificial eye member relative to the holding surface, it is possible to align it with the through-hole even if the position of the eye in the head body changes. As a result, the same artificial eye holding structure can be used even for head bodies with different eye positions, reducing manufacturing costs. [Effects of the Invention]

[0020] The artificial eye holding structure for a doll head according to the present invention not only allows the orientation of the artificial eye member to be easily adjusted, but also allows it to be used even if the position of the eye on the head body is different, thereby reducing manufacturing costs.

[0022] A doll head according to one embodiment of the present invention will be described with reference to FIGS.

[0023] 1 to 3, the doll head 100 of this embodiment comprises a head body 10, an artificial eye member 40, and an artificial eye holder 50, and the head body 10 and the artificial eye holder 50 form an artificial eye holding structure. Here, the doll is not limited to a humanoid doll, but also includes an animal doll, a robot doll, etc.

[0024] The head main body 10 is hollow and can be separated into a face member 20 that forms the face side and a head member 30 that forms the head side. The face member 20 and the head member 30 are detachable from each other. Therefore, the inside of the head main body 10 can be accessed by removing the head member 30 from the face member 20. In other words, the inside of the face member 20 can be accessed by removing the head member 30 from the face member 20 while the head main body 10 remains attached to the torso (not shown).

[0025] Specifically, the face member 20 and the head member 30 are connected by contacting their contact surfaces 21, 31. More specifically, an engaging protrusion 22 is formed on one of the contact surfaces 21, 31, and an engaging recess 32 is formed on the other. The face member 20 and the head member 30 are positioned relative to each other by engaging the engaging protrusion 22 with the engaging recess 32. In addition, magnets 23, 33 are provided at corresponding positions on both contact surfaces 21, 22, respectively, and the magnetic force of these magnets 23, 33 prevents the face member 20 and the head member 30 from accidentally coming off.

[0026] The face member 20 has at least a face portion 24 and a neck base portion 25. Through holes 26 are formed in the face member 20 at the positions of the left and right eyes. The inner peripheral surface 26s of this through hole 26 is tapered so that the diameter decreases from the inner opening end to the outer opening end. In addition, a fitting hole 27 for attaching the artificial eye holder 40 is formed in the face member 20 on the inner surface closer to the neck than the through hole 26. In this embodiment, the fitting hole 27 is formed in the neck base portion 25. This fitting hole 27 has a rectangular cross section and is located in the center of the head body 10 in the left-right direction.

[0027] Furthermore, the face member 20 is provided with a connecting mechanism 28 for connecting to the doll's body (not shown) provided at the base of the neck 25. The connecting mechanism 28 in this embodiment is a connecting hole into which a connecting shaft (not shown) provided on the doll's body is inserted, and is provided behind the fitting hole 27. Therefore, the fitting hole 27 is formed between the through hole 26 and the connecting mechanism 28.

[0028] The artificial eye member 40 is, for example, approximately hemispherical, as shown in FIG. 2. The artificial eye member 40 of this embodiment comprises a disk-shaped artificial eye body 41, an iris 42 provided on one end surface of the artificial eye body 41, a translucent convex lens body 43 covering one end of the artificial eye body 41, and a handle 44 protruding radially from the outer circumferential surface of the convex lens body 43. The artificial eye member 40 is designed so that the iris 42 can be seen through the convex lens body 43, and the convex spherical surface formed by this convex lens body 43 is the front surface 40a. The surface facing the opposite direction from the front surface 40a, i.e., the flat surface formed by the other end surface of the artificial eye body 41, is the back surface 40b. The iris 42 may be formed, for example, by drawing it directly on one end of the artificial eye body 41, or by drawing it on a sticker attached to that end.

[0029] As shown in Figures 1 and 3, the artificial eye holder 50 is, for example, generally T-shaped overall and elastically deformable toward the rear (occipital region), which is the opposite direction to the direction in which the iris 42 faces. The artificial eye holder 50 of this embodiment includes a shaft 51 fitted into the fitting hole 27 and an elastically deformable holding arm 52 fixed to the shaft 51. The shaft 51 has a rectangular cross section and is shaped to fit snugly into the fitting hole 27. The holding arm 52 has a pair of arms 53 extending from the shaft 51 in a direction perpendicular to its axial direction. The arms 53 elastically deform so as to flex circumferentially around the shaft 51, with the shaft 51 as the central axis. Each arm 53 has a holding surface 50s formed at its tip. The holding surface 50s is a convex spherical surface.

[0030] The artificial eye holder 50 is attached to the face member 20 by fitting the shaft 51 into the fitting hole 27. In this state, the artificial eye holder 50 rises from the base of the neck 25 of the face member 20 toward the head, and is positioned so that the holding surface 54 faces the through-hole 26 with a gap between them. Therefore, a holding space S for holding the artificial eye member 40 is formed between the holding surface 54 and the through-hole 26, and this holding space S is open toward the head.

[0031] Next, how to use the doll head 100 will be described.

[0032] First, the head member 30 is removed from the face member 20 of the head body 10. This allows access to the interior of the face member 20 through an opening on the rear side of the head. Then, the prosthetic eye member 40 is fitted into the holding space S. Specifically, the prosthetic eye member 40 is fitted into the holding space S with the front surface 40a facing the through-hole 26 and the back surface 40b facing the holding surface 50s. Note that the holding space S is open toward the head, so there is no obstacle in front of the holding space S, and the prosthetic eye member 40 can be easily fitted in.

[0033] When the artificial eye component 40 is fitted into the holding space S, the convex spherical surface 40a abuts against the inner circumferential surface 26s of the through-hole 26, and the flat back surface 40b abuts against the holding surface 50s, and is held between the inner circumferential surface 26s and the artificial eye holding body 50. In this state, the iris 42 can be seen through the convex lens body 43 from the outside of the head body 10 through the through-hole 26. Furthermore, the arm portion 53 is pushed by the artificial eye component 40 and elastically deforms slightly backward. Specifically, the arm portion 53 is pushed by the artificial eye component 40 and elastically deforms so as to bend in the circumferential direction of the shaft body 51, with the shaft body 51 as the central axis. As a result, the artificial eye component 40 is pressed toward the inner circumferential surface 26s by the restoring force of the arm portion 53. In other words, the artificial eye component 40 is biased by the artificial eye holder 50 toward the inner surface (inner peripheral surface 26s) of the head body 10 and is held so as not to move inadvertently.

[0034] Next, when changing the orientation of the artificial eye member 40 in the left-right direction, as shown in Figure 5, the artificial eye member 40 is rotated left and right with almost no relative movement relative to the holding surface 50s. At this time, the degree of bending of the arm portion 53 changes. Specifically, in this embodiment, as shown in Figures 5(a) and 5(b), when the artificial eye member 40 is rotated, the arm portion 53 bends more greatly. Note that when changing the orientation of the artificial eye member 40 in the up-down direction, the artificial eye member 40 is rotated up and down with almost no relative movement relative to the holding surface 50s. At this time, the degree of bending of the arm portion 53 also changes. In addition, the arm portion 53 elastically deforms so as to be twisted in a direction perpendicular to the extension direction.

[0035] The doll head 100 shown in Figures 6(a) and 6(b) is a modified version of the head body 10 of this embodiment, with only the eye position changed, and the other structures are the same as those of this embodiment. Specifically, the head body 10 shown in Figure 6(a) has the eyes positioned further away than in this embodiment, while the head body 10 shown in Figure 6(b) has the eyes positioned closer together than in this embodiment. As can be seen from these modifications, if the eye position of the head body 10 is changed, the prosthetic eye member 40 can be aligned with the through-hole 26 by moving it relative to the holding surface 50s.

[0036] According to the artificial eye holding structure of the doll head 100 of this embodiment, the holding surface 50s of the artificial eye holding body 50 is a convex spherical surface, so the orientation of the artificial eye member 40 can be easily changed by rotating it with almost no relative movement relative to the holding surface 50s. Furthermore, by moving the artificial eye member 40 relative to the holding surface 50s, it is possible to align it with the through-hole even if the position of the eye of the head body 10 changes. As a result, the same artificial eye holding structure can be used for head bodies with different eye positions, reducing manufacturing costs.

[0037] In addition, since the artificial eye holder 50 is elastically deformable, the artificial eye component 40 can be pressed against the inner peripheral surface 26s of the through-hole 26 and held there. This makes it difficult for the artificial eye component 40 to accidentally fall off and its orientation to shift. Furthermore, since the front-to-back spacing of the holding space S can be adjusted to match the shape of the artificial eye component 40, the artificial eye component 40 can be held even if its size changes to some extent.

[0038] <Other Embodiments> In the above embodiment, the holding surface is a convex spherical surface, but it may also be an ellipsoidal spherical surface. Furthermore, for example, the holding surface may be a convex curved surface. Specifically, the holding surface may be a convex curved surface that curves in the left-right direction, or a convex curved surface that curves in the up-down direction.

[0039] In the above embodiment, the holding arm of the artificial eye holder is elastically deformable, but for example, the shaft may be elastically deformable, or the entire artificial eye holder may be elastically deformable. Also, the artificial eye holder does not necessarily have to be elastically deformable.

[0040] In the above embodiment, the holding surfaces corresponding to the left and right eyes are provided on one artificial eye holder, but they may be provided on separate artificial eye holders.

[0041] In addition, in the above embodiment, the artificial eye holder is arranged to protrude from the neck side toward the head side beyond the through hole, but it may also be arranged to protrude, for example, from the head side toward the neck side.

[0042] In addition, in the above embodiment, the back surface of the artificial eye component is flat and the holding surface of the artificial eye holder is convex. However, for example, the back surface may be convex and the holding surface may be convex or flat. In other words, either the back surface or the holding surface may be convex, and the other may be convex or flat. Therefore, the artificial eye component is not limited to a hemispherical shape, but may be, for example, a spherical shape or an ellipsoidal shape. In other words, the back surface of the artificial eye component may be a convex curved surface, a spherical surface, or an ellipsoidal surface. In this case, the head body and the artificial eye holder may have the same configuration as those in the above embodiment.

[0043] In addition, parts of the various embodiments may be combined or modified as long as it does not go against the spirit of the present invention. [Explanation of symbols]
