Description

Doll eye drive mechanism

The present disclosure relates to a doll eye drive mechanism that enables movement of the doll's line of sight.

For example, as disclosed in Patent Document 1, two types of left and right eyes are housed inside the head of a doll, and can be switched from one to the other and vice versa by an external operation. It has been known. In the eye movement device of Patent Document 1, a fan-shaped eye holder with a central angle of about 120 degrees is supported inside the head so as to be rotatable around a vertically extending axis. The eye holder is formed with a first left eye, a first right eye, and a second left eye and a second right eye in order from left to right. By rotating the eye holder around the axis, the first left eye and the first right eye are exposed from the left and right eye holes, respectively, and the second left eye and the second right eye are exposed to the left and right eyes, respectively. It is possible to switch between the state of being exposed from the eye of the eye and the state of being exposed.

Japanese Patent Application Laid-Open No. 2020-92792

By the way, since the doll's line of sight is extremely important in creating the doll's expression, users have a need to change the doll's line of sight to change the expression in various ways.

However, in the eye movement device of Patent Document 1, since there are only two types of left and right eyes, the first eye and the second eye, there are only two types of line of sight that can be changed by the switching operation. In addition, since the moving direction of the eye holder is limited to the horizontal direction, it is impossible to change the line of sight in the vertical direction. Therefore, for example, it is impossible to create a line of sight between the line of sight formed by the first eye and the line of sight formed by the second eye, or to create a line of sight slightly shifted from the line of sight formed by the first eye or the second eye. , and the degree of freedom in changing facial expressions was low.

In addition, depending on the doll, the opening area of the eye sockets on the face is widened, and some large eyeballs are housed inside the head. In order to rotatably incorporate the fan-shaped eye holder having a central angle of about 120 degrees of Patent Document 1 in such a doll, it is necessary to attach at least four large eyeballs to the eye holder so as to line up in the left-right direction. As a result, the eye holder becomes large, and it may be difficult to accommodate it inside the head.

In addition, it is possible to further diversify facial expressions by changing not only the line of sight, but also the size of the pupil, the color of the cornea, and the color and shape of the iris. I need to replace the eyeball. However, due to the fact that each eyeball is made by a different person, the size of each eyeball varies. For example, if the size of the eyeball after replacement is smaller than that of the original eyeball, the gap between the periphery of the eyeball of the face and the surface of the eyeball becomes large, resulting in poor appearance. On the contrary, if the size of the eyeball after replacement is larger than the original eyeball, it becomes difficult to incorporate the eyeball itself.

The present disclosure is made in view of this point, and the purpose thereof is to make it possible to replace eyeballs with different sizes without impairing the appearance, and to easily create a line of sight in various directions. The object is to make the eyeball driving mechanism compact while doing so.

In order to achieve the above object, one aspect of the present disclosure can assume a doll eyeball drive mechanism that is housed inside the doll's head. The eyeball driving mechanism for a doll includes a left eyeball base to which a left eyeball exposed from a left eyeball formed on the face of the doll is attached, and a right eyeball base exposed from the right eyeball formed on the face of the doll. A right eyeball base to which an eyeball is attached, and the left eyeball base and the right eyeball base are rotatable about axes extending in the vertical direction at intervals corresponding to the intervals between the left eyeball and the right eyeball. a first supporting member that supports the head; a second supporting member that is attached inside the head portion and supports the first supporting member so as to be vertically swingable; and a biasing member that biases the first supporting member forward. and a force member.

According to this configuration, the left eyeball base and the right eyeball base supported by the first supporting member can be rotated in the horizontal direction. You can change direction steplessly. In addition, since the first support member that supports the left eyeball base and the right eyeball base is vertically swingable, the left eyeball and the right eyeball are rotated vertically to make the line of sight vertically neutral. can be changed in stages. In this way, by rotating one set of eyeballs housed inside the head horizontally and vertically, there is no need to incorporate a plurality of sets of eyeballs as in the conventional example, and the eyeball drive mechanism can be made compact.

Furthermore, since the first support member that supports the left eyeball base and the right eyeball base is biased forward, if the eyeballs become smaller when the left and right eyeballs are changed to different eyeballs, the first support member moves forward, the left eyeball base and the right eyeball base move forward, thereby maintaining a predetermined gap between the left and right eyeballs and the rim of the eye socket. On the other hand, when the left and right eyeballs are changed to different eyeballs and the eyeballs become larger, the first support member moves backward, thereby moving the left eyeball base and the right eyeball base backward. It becomes possible to incorporate the left and right eyeballs.

In another aspect of the present disclosure, the doll extends in the left-right direction, and the left end and the right end are connected to the left eyeball base and the right eyeball base, respectively, and the eyeball base is one of the left eyeball base and the right eyeball base. A transmission member may be provided for transmitting the turning force of one eyeball base to the other eyeball base.

According to this configuration, when a turning force is applied to one eyeball base out of the left eyeball base and the right eyeball base, the turning force is transmitted to the other eyeball base via the transmission member. can be linked.

In another aspect of the present disclosure, one eyeball base of the left eyeball base and the right eyeball base is connected to a tip end of an operation member for transmitting an operation force, and the operation member is a head of the doll. It may extend to the outside of the part.

According to this configuration, by pulling the operation member from the outside of the head, the pulling force can be transmitted to the eyeball base to change the line of sight.

Another aspect of the present disclosure includes a driven gear fixed to one of the left eyeball base and the right eyeball base, a drive gear meshing with the driven gear, and a motor driving the drive gear. may

With this configuration, it is possible to change the line of sight by rotating the eyeball base with the rotational force of the motor.

In another aspect of the present disclosure, an eyelid member formed to cover a portion above the corneal portion of the left eyeball may be attached to the upper portion of the left eyeball base.

According to this configuration, when the left eyeball base rotates downward, the eyelid member also rotates in the same direction and is arranged in the left eye socket. As a result, the left eyeball cannot be seen through the eye socket, and the eyes are closed. In other words, by attaching the eyelid member to the upper part of the left eyeball base, the eyes can be opened and closed, and various facial expressions can be created. A similar eyelid member can be attached to the right side.

As described above, the left eyeball base and the right eyeball base are rotatably supported in the horizontal direction by the first supporting member, and the first supporting member is supported by the second supporting member so as to be vertically swingable, Since the first supporting member is urged forward by the urging member, it is possible to replace the eyeball with another eyeball of a different size without impairing the appearance, and the line of sight in various directions can be easily created. In addition, the eyeball driving mechanism can be made compact.

The connected portion 24 has a plate-like portion 24a and a connecting shaft portion 24b, and the operation plate portion 25 has a through hole 25a.

The first support member 30 is a member that supports the left eyeball base 10 and the right eyeball base 20 at intervals corresponding to the intervals between the left eyeball 101a and the right eyeball 101b, and is made of, for example, a hard resin material. there is That is, the first support member 30 includes an upper support portion 31 extending in the left-right direction at the upper end portion of the first support member 30, a lower support portion 32 extending in the left-right direction at the lower end portion of the first support member 30, A pair of curved portions 33 extending vertically so as to connect the upper support portion 31 and the lower support portion 32 are provided. The upper support portion 31, the lower support portion 32, and the curved portion 33 are integrally formed of a resin material, but may be configured by combining separate members.

A left end portion of the upper support portion 31 protrudes forward, and an upper shaft portion 31a protruding downward is formed at the left end portion. The left upper shaft portion 31 a is relatively rotatable while being inserted into the shaft insertion hole 12 of the left eyeball base 10 . The right end portion of the upper support portion 31 also protrudes forward, and an upper shaft portion 31b protruding downward is formed at the right end portion. The right upper shaft portion 31 b is relatively rotatable while being inserted into the shaft insertion hole 22 of the right eyeball base 20 . A connecting hole 31 c is formed in the central portion of the upper support portion 31 in the left-right direction.

A lower bearing hole 32 a is formed at the left end of the lower support part 32 , and a lower bearing hole 32 b is formed at the right end of the lower support part 32 . The lower support shaft 13 of the left eyeball base 10 is inserted into the lower bearing hole 32a so as to be relatively rotatable. The lower support shaft 23 of the right eyeball base 20 is inserted into the lower bearing hole 32b so as to be relatively rotatable. When inserting the

lower support shafts

13 and 23, the upper support portion 31, the lower support portion 32, and the curved portion 33 may be elastically deformed using the elasticity of the resin material. The vertical interval between the upper support portion 31 and the lower support portion 32 is set by the vertical dimension of the curved portion 33, so that the

lower support shafts

13 and 23 and the

upper shaft portions

31a and 31b do not come off. It is supposed to be blocked.

With the

lower support shafts

13, 23 inserted into the

lower bearing holes

32a, 32b, respectively, and the

upper shafts

31a, 31b inserted into the shaft insertion holes 12, 22, the left eyeball base 10 moves vertically. The right eyeball base 20 is rotatable about the lower support shaft 13 and the upper shaft portion 31a extending vertically, and the right eyeball base 20 is rotatable about the lower support shaft 23 and the upper shaft portion 31b that extend vertically.

As shown in FIG. 5 , the pair of curved portions 33 are spaced apart from each other in the left-right direction. It connects the portion between the

lower bearing holes

32a and 32b. As shown in FIG. 2 , each curved portion 33 is curved such that the center portion in the vertical direction is positioned rearmost, and therefore, the closer the upper end portion and the lower end portion, the closer the curved portion 33 is positioned to the front. The curved portion 33 may be curved in an arc shape.

As shown in FIG. 3 , the doll's eyeball drive mechanism 1 includes a transmission member 60 . This transmission member 60 is also made of the same resin material as the first support member 30 . The transmission member 60 extends in the left-right direction behind the curved portion 33 . As shown in FIG. 6, the transmission member 60 has a left end formed with a connection hole 60a into which the connection shaft 14b of the left eyeball base 10 is inserted, and a right end of the transmission member 60 formed with a right eyeball base. A connecting hole 60b into which the connecting shaft portion 24b of 20 is inserted is formed. When the connecting shaft portion 14b of the left eyeball base 10 is inserted into the connecting hole 60a, both are relatively rotatable. In addition, in a state in which the connecting shaft portion 24b of the right eyeball base 20 is inserted into the connecting hole 60b, both are relatively rotatable. be. In this connected state, the turning force of one of the left eyeball base 10 and the right eyeball base 20 can be transmitted to the other eyeball base by the transmission member 60 . For example, when the left eyeball base 10 is rotated, the turning force is transmitted to the right eyeball base 20 via the connecting shaft portion 14b, the transmission member 60, and the connecting shaft portion 24b. Further, when the right eyeball base 20 is rotated, the turning force is transmitted to the left eyeball base 10 via the connecting shaft portion 24b, the transmission member 60, and the connecting shaft portion 14b. In this manner, the left eyeball base 10 and the right eyeball base 20 can be interlocked by the transmission member 60, so that the left and

right eyeballs

2 and 3 can always be oriented in the same direction.

The second support member 40 is a member that is attached inside the head 100 and supports the first support member 30 so that it can swing vertically. The second support member 40 includes a rod-shaped member 41 extending in the front-rear direction, a plate-shaped member 42 and a rear end member 43 . The rod-like member 41 is arranged in the center portion in the left-right direction inside the head portion 100 . The cross-sectional shape of the rod-shaped member 41 in the direction orthogonal to the longitudinal direction is rectangular, but may be circular. An engaging portion 41a is provided at the front end portion of the rod-shaped member 41 so as to protrude forward. The engaging portion 41a is a portion that is inserted into an engaging hole (not shown) formed in the back surface of the face member 101 and that engages with the inner surface of the engaging hole. A pin portion 41b projecting forward is also provided at the front end portion of the rod-shaped member 41 . The pin portion 41b is fitted into a pin fitting hole (not shown) formed in the back surface of the face member 101. As shown in FIG. The front end portion of the bar member 41 can be detachably attached to the back surface of the face member 101 by the engaging portion 41a and the pin portion 41b.

As shown in FIG. 4, the rod-shaped member 41 passes between the left and

right eyeballs

2 and 3, passes between the left and right

curved portions

33 and 33, and protrudes rearward beyond the

curved portions

33 and 33. As shown in FIG. As shown in FIG. 2 , the vertical dimension of the rod-shaped member 41 is set sufficiently shorter than the vertical dimension of the separation between the upper support portion 31 and the lower support portion 32 . As a result, the vertical swing of the first support member 30 is not hindered by the bar member 41 .

A plate-like member 42 is attached to the rod-like member 41 . As shown in FIG. 6, the plate-like member 42 is formed with an insertion hole 42a through which the rod-like member 41 is inserted. It is attached to the rod-shaped member 41 so as to be slidable in the front-rear direction. The front surface of the plate-like member 42 is a surface that comes into sliding contact with the rear surfaces of the pair of

curved portions

33 , 33 . In addition, the dimension of the plate-like member 42 in the left-right direction is set so that it reaches from the left curved portion 33 to the right curved portion 33, and when the front surface of the plate-like member 42 is in sliding contact with both

curved portions

33, 33, The plate member 42 can be stabilized immediately.

The rear end member 43 is attached to the rear end portion of the rod-shaped member 41 . That is, the rear end portion of the rod-shaped member 41 is formed with an engaging claw 41c, while the rear end member 43 is formed with an insertion hole 43a through which the rear end portion of the rod-shaped member 41 is inserted. As shown in FIG. 3, with the rear end portion of the rod-shaped member 41 inserted through the insertion hole 43a, the engaging claw 41c engages with the peripheral portion of the insertion hole 43a to function as a retainer.

The biasing member 50 is composed of an elastic member such as a coil spring or rubber, and in this embodiment is composed of a metal coil spring that expands and contracts in the front-rear direction. A biasing member 50 is arranged between the rear end member 43 and the plate member 42 . That is, the biasing member 50 is inserted through the portion of the rod-shaped member 41 on the rear side of the plate-shaped member 42 . A front end portion of the biasing member 50 contacts the rear surface of the plate member 42 , and a rear end portion of the biasing member 50 contacts the front surface of the rear end member 43 .

The rear surface of the rear end member 43 is supported while in contact with the inner surface of the rear member 102 forming the head 100 of the doll. Therefore, the biasing force of the biasing member 50 acts in the direction of pushing the plate member 42 forward. Since the plate-like member 42 is slidable in the front-rear direction with respect to the rod-like member 41, the biasing force of the plate-like member 42 acts in the direction of pushing the pair of

curved portions

33, 33 forward. As a result, the biasing member 50 biases the first support member 30 forward through the plate member 42 . When the first support member 30 is urged forward, the left eyeball base 10 and the right eyeball base 20 are urged forward, so the left and

right eyeballs

2 and 3 are also urged forward. Therefore, the left and

right eyeballs

2 and 3 are urged toward the peripheral portions of the left and right eye holes 101a and 101b, respectively, so that the gap between the

eyeballs

2 and 3 and the peripheral portions of the eye holes 101a and 101b is a predetermined gap. is held in

Here, a case where the left and

right eyeballs

2 and 3 are changed to different eyeballs (not shown) will be described. When the

eyeballs

2 and 3 are changed to other eyeballs, the eyeballs may have a different size than the

original eyeballs

2 and 3. For example, when the left and

right eyeballs

2 and 3 are changed to different eyeballs and the eyeballs after the change become smaller, the biasing force of the biasing member 50 moves the first support member 30 forward to move the left eyeball 30 forward. The eyeball base 10 and the right eyeball base 20 move forward, thereby maintaining a predetermined gap between the left and right eyeballs that have become smaller and the peripheral edges of the eye holes 101a and 101b. On the other hand, when the left and

right eyeballs

2 and 3 are changed to different eyeballs and the eyeballs after the change become larger, the first supporting member 30 moves backward against the biasing force of the biasing member 50 . , the left eyeball base 10 and the right eyeball base 20 are moved backward, so that it is possible to incorporate the enlarged left and right eyeballs.

As shown in FIGS. 3 and 4, an eyelid member 61 is attached to the upper portion of the left eyeball base 10 so as to cover a portion of the left eyeball 2 above the corneal portion 2a. Specifically, the eyelid member 61 is formed in a plate shape that curves along the upper portion of the left eyeball 2 . A lower edge portion of the eyelid member 61 is positioned above the corneal portion 2a and extends in the left-right direction. The upper portion of the eyelid member 61 is fixed to the upper portion of the left body portion 11 , thereby allowing the eyelid member 61 to interlock with the left body portion 11 . An eyelid member 62 similar to that on the left side is also attached to the upper portion of the right eyeball base 20 . The

eyelid members

61 and 62 may be fixed to the

upper shaft portions

31a and 31b of the upper support portion 31, respectively. Also, the

eyelid members

61 and 62 are detachably attached like the

eyeballs

2 and 3, for example, by adhesive, double-sided tape, nail fitting, or the like. Also, although not shown, upper eyelashes can be attached to the

eyelid members

61 and 62 .

When exchanging the

eyeballs

2 and 3, the

eyelid members

61 and 62 can be removed once and then the exchange work can be performed. Also, for example, if the

eyeballs

2 and 3 are replaced with smaller ones, there is a risk that a gap will be formed between the

eyelid members

61 and 62 and the

eyeballs

2 and 3. However, in this embodiment, the

eyelid members

eyeballs

2 and 3 to the right is connected to the through hole 212g of the right eyeball base 212, and the other end of the right spring 221 is also connected to the through hole 212g. there is

The eyelid forming member 230 has a left eyelid portion 231 that serves as the left eyelid, a right eyelid portion 232 that serves as the right eyelid, and a connecting portion 233 that connects the left eyelid portion 231 and the right eyelid portion 232, These are integrally molded from a resin material. The left eyelid part 231 is arranged above the left eyeball 2 and has a plate shape that is curved more than the eyeball 2 . The left eyeball 2 is rotatable separately from the left eyelid portion 231 . Similarly, the right eyelid portion 232 is arranged above the right eyeball 3 and has a plate-like shape curved more than the eyeball 3 . The right eyeball 3 is also rotatable separately from the right eyelid portion 232 . The surfaces (outer surfaces) of the left eyelid portion 231 and the right eyelid portion 232 are surfaces facing the outside through the eye holes 101a and 101b, and various decorations (for example, decoration similar to makeup) can be applied.

The left eyelid part 231 and the right eyelid part 232 are arranged with a predetermined interval in the horizontal direction so as to correspond to the interval between the left and

right eyeballs

2 and 3 . A connecting portion 233 is provided to maintain this predetermined distance. The connecting portion 233 is formed in a columnar shape or a rod shape having a circular cross section that extends in the left-right direction from the right end portion of the left eyelid portion 231 to the left end portion of the right eyelid portion 232 . The connecting portion 233 and the left eyelid portion 231 and the right eyelid portion 232 are not relatively rotatable. The connecting portion 233 is a shaft extending in the left-right direction, and as will be described later, is a portion that serves as a rotation shaft for rotating the entire eyeball support unit 210 including the left eyelid portion 231 and the right eyelid portion 232 .

That is, as shown by the phantom lines in FIG. 16, the connecting portion 233 is inserted into the concave portion 203a of the frame 200 from the rear to the front. The connecting portion 233 is inserted into the concave portion 203a and supported by the inner surface of the concave portion 203a so as to be rotatable about an axis extending in the left-right direction with respect to the frame 200. As shown in FIG. Furthermore, the connecting portion 233 is relatively displaceable in the depth direction (front-rear direction) of the recessed portion 203a while being inserted into the recessed portion 203a.

A left fixed plate portion 231 a fixed to the left eyelid fixing portion 241 c of the upper support portion 214 is formed on the upper portion of the left eyelid portion 231 . The left fixing plate portion 231a can be fixed to the left eyelid fixing portion 241c by a concave-convex fitting structure, a nail fitting structure, or the like, or may be fixed by adhesion or the like. For example, one of the left fixing plate portion 231a and the left eyelid fixing portion 241c is formed with a concave portion or a hole (for example, the left support hole 214e), and the other is formed with a convex portion, and the convex portion is fitted into the concave portion or the hole. By combining them, the left eyelid portion 231 can be attached to the upper support portion 214 so as to be vertically rotatable. Similarly, a right fixing plate portion 232a fixed to the right eyelid fixing portion 241d of the upper support portion 214 is formed on the upper portion of the right eyelid portion 232 so that the right eyelid portion 232 can be fixed to the upper support portion 214. It has become. For example, one of the right fixing plate portion 232a and the right eyelid portion 232 is formed with a recess or hole (for example, the right support hole 214f), and the other is formed with a protrusion, and the protrusion is fitted into the recess or hole. By doing so, the right eyelid portion 232 can be attached to the upper support portion 214 so as to be rotatable in the vertical direction. 22 shows the right eyelid portion 232 in the normal state, and FIG. 23 shows the state in which the right eyelid portion 232 is rotated upward. For example, when using an eyeball (not shown) that is larger than the eyeball 3 shown in FIG. gap is automatically minimized, allowing the use of a large eyeball 3. Further, since the front end of the right eyelid 232 is the front end of the eyeball support unit 210, even if the size of the eyeball 3 changes when the magnet mounting member 205 is adhered to an arbitrary position, there is no problem. The same is true for the left side.

For example, when the

eyeballs

2 and 3 are large, it is necessary to displace the eyeball support unit 210 backward to accommodate the size of the

eyeballs

2 and 3. By moving backward, the eyeball support unit 210 can be displaced backward by a distance corresponding to the size of the

eyeballs

2 and 3 . Also, when the

eyeballs

2 and 3 are small, it is necessary to move the eyeball support unit 210 forward to correspond to the size of the

eyeballs

2 and 3. By moving forward, the eyeball support unit 210 can be displaced forward by a distance corresponding to the size of the

eyeballs

2 and 3 .

The magnet mounting member 205 is a member for preventing rearward movement of the eyeball support unit 210 . Specifically, the magnet mounting member 205 is fixed to the lower projecting portion 203, and the rear surface 213c (also shown in FIG. 18) of the support member 213 is arranged in front of the magnet mounting member 205. It's like As shown in FIG. 17, the rear surface 213 is formed with a notch 231d that opens downward so that the lower projecting portion 203 can be inserted from below. When the eyeball support unit 210 is rotated downward around the connecting portion 233, the lower protruding portion 203 is inserted into the notch portion 231d, so that the rotation range in the vertical direction can be widened. Further, the eyeball support unit 210 is positioned in the left-right direction by inserting the lower projecting portion 203 into the notch portion 231d.

The front surface of the magnet mounting member 205 slidably abuts against the rear surface 213c of the support member 213 while the lower projecting portion 203 is inserted into the notch portion 231d. Since this prevents the eyeball support unit 210 from moving backward, the distance in the depth direction between the

eyeballs

2 and 3 and the eye holes 101a and 101b can be kept constant. If the

eyeballs

2 and 3 are large, the magnet mounting member 205 can be shifted backward and fixed to the lower projecting portion 203. If the

eyeballs

2 and 3 are small, the magnet mounting member 205 can be shifted forward. can be fixed to the lower protruding portion 203 by Also, the position of the magnet mounting member 205 can be changed depending on the size and shape of the left eyelid portion 231 and the right eyelid portion 232 .

A pair of left protrusions 231b protruding outward from the left eyelid 231 and extending around the rotation center line (a straight line extending in the left-right direction) of the connecting portion 233 are provided on both left and right ends of the surface of the left eyelid 231. , 231b are formed. The decoration is applied to the portion between the pair of

left ribs

231b, 231b on the surface of the left eyelid 231. As shown in FIG. The tip of the left projection 231b in the projecting direction comes into sliding contact with the periphery of the left eye hole 101a on the inner surface of the face member 101 when the left eyelid 231 is rotated. As a result, the decoration applied to the surface of the left eyelid portion 231 does not come into contact with the inner surface of the facial member 101, so that the decoration portion is prevented from being scratched or damaged. Moreover, when the head 100 is viewed from the front, the distance in the depth direction between the surface of the left eyelid portion 231 and the peripheral portion of the eye hole 101a is kept constant, so that when the eyelids are closed, a natural facial expression is realized. can. Similarly, a pair of

right ribs

232b, 232b are also formed on both left and right ends of the surface of the right eyelid 232. As shown in FIG.

FIG. 13 shows a state in which the eyelids are open, that is, a state in which the eyeball support unit 210 has rotated upward around the connecting portion 233 . Since the eyeball support unit 210 is constantly urged to rotate upward by the urging forces of the left and right springs 221, it will rotate until it stops as shown in FIG. 13 unless an external force is applied. Further, the supporting member 213 is urged forward by the urging force of the spring 221 .

In the state shown in FIG. 13, the left and

right eyeballs

2 and 3 face straight forward and face the outside through the eye holes 101a and 101b, while the surfaces of the left eyelid portion 231 and the right eyelid portion 232 face upward. Most of them enter the head 100 through the eye holes 101a and 101b and are hardly visible from the outside. When the eyelids are open, the second magnet 213b of the eyeball support unit 210 is attracted to the first magnet 204 fixed to the frame 200. As shown in FIG. This suppresses rattling of the eyeball support unit 210 . Note that the first magnet 204 and the second magnet 213b may be omitted.

A connection hole 213d to which the tip of the upper operation member 70 is connected is formed in the center of the support member 213 in the left-right direction. As shown in FIG. 20 and the like, the intermediate portion of the upper operation member 70 includes a first horizontal bar 249 fixed to the upper front portion of the frame 200 and a second horizontal bar 250 fixed above it. , and routed from above to the rear of the second horizontal bar 250 . The first horizontal bar 249 and the second horizontal bar 250 are located above and forward of the connecting portion 233 . Also, the first horizontal bar 249 is located in front of the second horizontal bar 250 . Therefore, when the upper operation member 70 is pulled rearward, a forward force acts on the portion of the support member 213 above the connecting portion 233 . When this forward force becomes larger than the urging force of the spring 221 and the attraction force of the first magnet 204 and the second magnet 213b, the eyeball support unit 210 rotates downward around the connecting portion 233 . This rotation angle allows the line of sight to be directed downward.

As shown in FIGS. 19 and 21, when the downward rotation angle of the eyeball support unit 210 is increased, the eyelids are closed. In this state, the left and

right eyeballs

2 and 3 are directed downward and enter the head 100 through the eye holes 101a and 101b, and are hardly visible from the outside. On the other hand, the left eyelid portion 231 and the right eyelid portion 232 face the front and face the outside through the eye holes 101a and 101b. This makes the eyelids appear closed.

An engaging portion 70a having a larger outer diameter than other portions can be provided in the intermediate portion of the upper operating member 70. The engaging portion 70a can be configured by a hump or the like when the upper operating member 70 is a thread, for example. On the other hand, the rear fixing member 206 is formed with an insertion hole 206a through which the intermediate portion of the upper operation member 70 is inserted, and a slit 206b that communicates with the insertion hole 206a. The width of the slit 206b is set narrower than the outer diameter of the engaging portion 70a. Further, the formation position of the engaging portion 70a is set so that the engaging portion 70a comes out rearward from the insertion hole 206a when the eyeball support unit 210 is rotated until the eyelids are closed. By inserting the engaging portion 70a protruding rearward from the insertion hole 206a into the slit 206b, the upper operation member 70 can be stopped and the closed state of the eyelids can be maintained.

Therefore, according to the eyeball driving mechanism 1 for a doll according to the third embodiment, the left eyeball base 211 and the right eyeball base 212 are supported by the support member 213 so as to be rotatable in the left-right direction, as in the first embodiment. , it is possible to easily create lines of sight in various directions. In addition, since the eyelid forming member 230 can be rotated around the connecting portion 233 extending in the left-right direction, the eyelids can be switched from the closed state to the open state and from the open state to the closed state. can be done easily.

(Modification of Embodiment 3)
24 to 26 show a doll eye drive mechanism 1 according to a modification of the third embodiment. In this modification, a cam 235 is provided on the right side of the eyelid forming member 230 . The eyelid forming member 230 and the cam 235 rotate integrally. The cam 235 is formed with a convex portion 235a protruding in the radial direction.

On the other hand, a fixing member 104 is fixed to the inner surface of the face member 101 . The fixed member 104 is formed with an abutment surface 104a with which the convex portion 235a abuts when the eyelid forming member 230 rotates. The contact surface 104a extends in the up-down direction and is slanted so as to move forward as it goes upward. Although not shown, the left side is similarly constructed.

FIG. 24 shows a state in which the eyelids are open, and at this time, the convex surface portion 235a is in contact with the portion above the central portion of the contact surface 104a in the vertical direction. FIG. 25 shows a state in which the opened eyelids are in the process of being closed, and at this time, the convex surface portion 235a abuts on the vertical central portion of the abutting surface 104a. As a result, the entire eyelid forming member 230 can be moved backward, so that the left eyelid portion 231 and the right eyelid portion 232 do not contact the lower edges of the left eyelid 101a and the right eyelet 101b, respectively. , can run smoothly.

Fig. 26 shows a state in which the eyelids are completely closed. In this state, the convex portion 235a contacts the lower end portion of the contact surface 104a. As a result, the entire eyelid forming member 230 moves forward compared to the case shown in FIG. become close. Therefore, almost no gap is formed between the surfaces of the left eyelid portion 231 and the right eyelid portion 232 and the peripheral portions of the left eyelid 101a and the right eyelet 101b.

The above-described embodiments are merely examples in all respects and should not be construed in a restrictive manner. Furthermore, all modifications and changes within the equivalent range of claims are within the scope of the present invention.

As described above, the doll eyeball drive mechanism according to the present invention can be used to diversify facial expressions by enabling the left and right eyeballs of a doll to be driven.
