Description

[Technical field]

[0001] The present invention relates to a lock mechanism for a movable shaft in a part attached to a doll toy, a movable shaft, and a doll toy. [Background technology]

[0002] In a doll toy, there are parts (components) that are attached so as to be rotatable around a certain movable axis. When such a part is rotated, a force (tension) is generated in the opposite direction to the insertion direction of the movable axis into the part. This force in the opposite direction acts so as to cause the movable axis to come out of the part. Therefore, it is necessary to prevent the movable axis from coming out due to the force in the opposite direction that may be generated when the part is rotated.

[0003] Patent Document 1 proposes an assembly toy having a mechanism for locking each of a plurality of components by rotating a support member, which includes a rod-shaped body inserted into each through-hole of the components, about an axis. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2012-148172 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned conventional technology, although it is possible to prevent the support member from coming off due to the force in the opposite direction, it is not assumed that a force in the rotation direction about the axis will be applied to the support member. In other words, when a force in the rotation direction is applied to the support member, the support member may come off (detach) from each component, or rotate back to the initial position where it was inserted. In such a configuration, for example, in a part that is attached to a doll body in a rotatable manner, such as a weapon, there is a risk that the movable axis may come off frequently.

[0006] The present invention provides a locking mechanism that prevents the movable shaft of a part that is rotatably attached to a doll body from coming off, for example. [Means for solving the problem]

[0007] The present invention provides a locking mechanism for a movable shaft in a part attached to a doll body, the mechanism comprising: a movable shaft that rotates a part of the part, the movable shaft having a first restricting portion that restricts the movable shaft from coming out of the part when the movable shaft is inserted into the part and rotated to a predetermined angle around the axial direction; and a fastener that engages the movable shaft inserted into the part and restricts the movement of the movable shaft in the rotational direction.

[0008] The present invention is also characterized in that it provides a movable shaft for a part attached to a doll body, the movable shaft having a first regulating portion that, when inserted into the part and then rotated to a predetermined angle around the axial direction, prevents the movable shaft from coming out of the part, and a second regulating portion that, when inserted into a fastener, regulates the movement of the movable shaft in the rotational direction. Effect of the Invention

[0009] According to the present invention, it is possible to prevent the movable shaft of a part that is rotatably attached to the doll body from coming off. [Brief description of the drawings]

[0011] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more features among the multiple features described in the embodiments may be arbitrarily combined. In addition, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0012] <Appearance of doll toy> First, an example of the external configuration of a doll toy to which a rotatable part according to the present embodiment is attached will be described with reference to Figs. 1 and 2. Fig. 1 shows the external front view of the doll toy 100, and Fig. 2 shows the external rear view of the doll toy 100. Note that, although an example of attaching a rotatable part to a doll toy will be described here, this is not intended to limit the present invention. In short, any article to which a rotatable part can be attached may be used. In addition, a weapon will be described as an example of a rotatable part, but this is not intended to limit the present invention with respect to the type or mounting position of the weapon. Any part having a movable axis (rotation axis) such as the rotatable part of the present invention described below may be used, and for example, it can be applied to the shoulder joint of a doll body in a doll toy. In this case, the arm attached to the shoulder joint operates rotatably.

[0013] The doll toy 100 includes a doll body composed of a head 101, a torso 102, arms 103, and legs 104, and a weapon 105 attached to the doll body. The head 101 is attached to the torso 102 and is located in the area indicated by the dotted line in FIG. 1. The torso 102 is further attached with arms 103 including a right arm and a left arm, and legs 104 including a right leg and a left leg. The weapon 105 is a part attached to the doll body, and in this embodiment, as shown in FIG. 2, it is attached from the back of the doll body to the shoulders. In addition, a part of the weapon 105 is attached to the doll body so as to be rotatable. In this embodiment, the weapon 105 is attached and fixed to the back of the doll body, and a part (cylindrical part) of the weapon 105 located on both upper shoulders is rotatable.

[0014] <Weapon (parts) configuration> Next, the configuration of the weapon 105, which is a rotatable part according to this embodiment, will be described with reference to Fig. 3. Fig. 3(a) is an enlarged rear view of the weapon 105, and Fig. 3(b) is an enlarged side view of the weapon 105.

[0015] The weapon 105 is configured to include weapon units 201a and 201b, a base member 202, and a mounting member 203. The weapon units 201a and 201b are configured symmetrically. The detailed configuration of each weapon unit 201a and 201b will be described later with reference to FIG. 4. The weapon units 201a and 201b are attached to the base member 202 so as to be able to rotate individually.

[0016] As shown in FIG. 3(b), the mounting member 203 is inserted into the torso 102 to fix and mount the weapon 105 to the doll body. The weapon parts 201a and 201b mounted on the doll body can rotate in the direction of the arrow 210 around their respective rotation shafts 204. The dotted line 211 shows the state when rotated. In this way, the weapon parts 201a and 201b, which are part of the weapon 105, can each rotate, and during the rotation, forces are applied in the direction in which the weapon parts 201a and 201b are removed and in the direction of rotation. These forces are applied to the movable shafts of the weapon parts 201a and 201b, which will be described later, and may act to detach the movable shafts from the respective weapon members. Therefore, the rotatable parts according to this embodiment are provided with a locking mechanism to prevent the movable shafts from detaching.

[0017] <Weapon (part) detailed configuration> Next, a detailed configuration of the weapon 105, which is a rotatable part according to this embodiment, will be described with reference to Fig. 4. Fig. 4(a) is an exploded view of the weapon 105, and Fig. 4(b) is an exploded view of the weapon section 201a.

[0018] As shown in Fig. 4(a), the weapon units 201a and 201b are rotatably attached by inserting a spherical portion, which is one end of a movable shaft, into the base member 202. As shown in the figure, the weapon units 201a and 201b are symmetrical and have the same basic structure. Therefore, the detailed structure of the weapon unit will be described below by taking the weapon unit 201a as an example.

[0019] As shown in Fig. 4(b), the weapon section 201a is configured to include weapon members 401, 402, a movable shaft 403, and a fastener 404. The movable shaft 403 is inserted into the weapon member 401 and rotated 180 degrees, and then inserted into the weapon member 402. Furthermore, the fastener 404 is inserted into the weapon member 402 from the opposite direction to the movable shaft 403, and engages the movable shaft 403 to fix its rotation.

[0020] <Configuration of movable shaft and fastener> Next, the configurations of the movable shaft 403 and the fastener 404 according to this embodiment will be described with reference to Fig. 5. Fig. 5(a) shows the configuration of the movable shaft 403, and Fig. 5(b) shows the configuration of the fastener 404.

[0021] First, the configuration of the movable shaft 403 will be described. The movable shaft 403 is composed of a shaft member 501 and end portions 502 and 504. As shown in FIG. 5(a), the shaft member 501 has a rib structure consisting of a plurality of ribs, and has a restricting portion 503 and a restricting plate 506. The restricting portion 503 is formed as a part of a predetermined rib, and is formed higher than other portions of the predetermined rib and other ribs. It is not intended to limit the present invention, and may be formed across a plurality of ribs, for example. This increases the thickness of the restricting portion 503, and the strength of the member can be further enhanced. In addition, a rib higher than the rib corresponding to the restricting portion 503 may be formed, or the movable shaft 403 may not be provided with a plurality of ribs, and only the restricting portion 503 may be formed. In addition, the shape and arrangement of the rib corresponding to the restricting portion 503 are not particularly limited, and it is sufficient if it can restrict the removal from the weapon member 401.

[0022] The restricting portion (first restricting portion) 503 is a portion for restricting the movable shaft 403 from rotating beyond a predetermined angle (180 degrees in this embodiment) after it has been inserted into the weapon member 401. Further rotation is restricted by the restricting portion 503 being caught by a restricting member (described later) provided on the weapon member 401. The restricting plate 506 is a member for restricting the insertion of the weapon member 401 into the insertion hole, and restricts the movable shaft 403 from being inserted further into the weapon member 401 by abutting against the outer wall of the insertion hole.

[0023] The end 502 is formed in a spherical shape, and is a part that is inserted into the base member 202 after the weapon part 201a is assembled. After insertion, because it is spherical, it can rotate within the space of the base member 202, which is the member into which it is inserted. The spherical shape of the end 502 is formed slightly larger than the diameter of the insertion opening of the base member 202, but since the doll toy 100 is formed of an elastic material such as plastic, it bends during insertion, widening the diameter and allowing it to be inserted. Therefore, after insertion, it is designed not to come out with a force that is sufficient to rotate the weapon part 201a for use. In this way, the movable shaft 403 is configured not to come out with a force within a predetermined range by being inserted into the base member 202, but when the weapon part 201a is rotated for use, it may come out of the weapon members 401, 402 as described above. The details of the lock mechanism that prevents the movable shaft 403 from coming out of the weapon members 401, 402 will be described later with reference to FIG. 6.

[0024] The end portion 504 has a slit (notch) 505 formed in a recessed shape. A protrusion 513 (described later) of the fastener 404 is inserted into the slit 505 to restrict the rotation of the movable shaft 403. Therefore, the slit 505 is an example of a second restricting portion that restricts the rotation of the movable shaft 403 about the axial direction.

[0025] Next, the configuration of fastener 404 will be described. Fastener 404 has an insertion portion 512, into which movable shaft 403 is inserted, provided in a part of fastener body 511. Furthermore, insertion portion 512 is formed with a protrusion 513 that is inserted into slit 505 of movable shaft 403. By inserting protrusion 513 into slit 505, which is a recess, it is possible to restrict rotation of movable shaft 403 about its axial direction.

[0026] <Lock mechanism> Next, the locking mechanism of the movable shaft 403 according to this embodiment will be described with reference to Fig. 6. The locking mechanism according to this embodiment is composed of a first restricting section that restricts the movable shaft 403 from coming out due to tension applied in the opposite direction to the direction in which the movable shaft 403 is inserted into the weapon member 401, and a second restricting section that restricts the rotation of the movable shaft 403 around its axial direction. Fig. 6(a) shows the functional configuration of the first restricting section, and Fig. 6(b) shows the functional configuration of the second restricting section.

[0027] First, the functional configuration of the first restricting unit will be described. FIG. 6(a) shows a state in which the movable shaft 403 is inserted into the weapon member 401 and rotated 180 degrees in the direction of the arrow 604. The weapon member 401 is provided with an insertion hole 601 for receiving the movable shaft 403. The insertion hole 601 is provided with a groove 602 through which the restricting portion 503, which is a part of a predetermined rib of the movable shaft 403, passes. Therefore, when the movable shaft 403 is inserted, the restricting portion 503 passes through the groove 602. After insertion, that is, in a state in which the restricting plate 506 of the movable shaft 403 abuts against the outer wall of the insertion hole 601 of the weapon member 401 and further insertion is not possible, the movable shaft 403 is rotated in the direction of the arrow 604. When rotated to a predetermined angle, the restricting portion 503 abuts against the restricting member 603 provided on the weapon member 401, and further rotation is restricted. In this state after rotation, the restricting part 503 moves from the groove 602 through which it passed during insertion to a position opposite the insertion hole 601. Therefore, in this state, the restricting part 503 cannot pass through the groove 602, and even if the above-mentioned tension is applied, the restricting part 503 abuts against the inner wall of the weapon member 401, thereby restricting the movable shaft 403 from coming out.

[0028] Next, the functional configuration of the second restricting unit will be described. FIG. 6(b) shows the state in which the movable shaft 403 is inserted into the fastener 404. For ease of explanation, the weapon members 401 and 402 are actually present between the movable shaft 403 and the fastener 404 as shown in FIG. 4(b), but are omitted in the figure. Also, the movable shaft 403 is shown in a state rotated 180 degrees as described with reference to FIG. 6(a). That is, the movable shaft 403 is rotated after being inserted into the weapon member 401, and then inserted into the insertion portion 512 of the fastener 404. At that time, the convex portion 513 formed on the insertion portion 512 of the fastener 404 is inserted into the slit 505 of the movable shaft 403. When inserted, the movement of the movable shaft 403 in the rotational direction is restricted. Therefore, the movable shaft 403 cannot rotate after the fastener 404 is attached; in other words, when the movable shaft 403 rotates, the restricting portion 503 rotates back to the position of the groove 602, thereby preventing the movable shaft 403 from coming off the weapon member 401.

[0029] In this way, the locking mechanism of the movable shaft according to this embodiment performs two-stage regulation (regulation by the first and second regulating parts). This allows for easy assembly, while suppressing the tension and rotational force applied to the movable shaft 403 after assembly, and can suitably prevent the movable shaft 403 from coming off the weapon members 401, 402.

[0030] <Assembly process> Next, the assembly process of the weapon 105 according to this embodiment will be described with reference to Fig. 7. The assembly process is carried out in the order of the arrows, that is, in the order of (a), (b), (c), (d), and (e).

[0031] First, in Fig. 7(a), the movable shaft 403 is inserted into the weapon member 401. When the movable shaft 403 is inserted into the weapon member 401 to a position where it can be inserted, that is, when it is inserted until the restricting plate 506 abuts against the outer wall of the insertion hole 601 of the weapon member 401, the movable shaft 403 is rotated in the direction of the arrow 604 in Fig. 7(b). Here, an example of rotating 180 degrees is described, but this is not intended to limit the present invention, and it is sufficient if the angle is such that the restricting portion 503 is rotated to a position sufficiently separated from the groove 602.

[0032] Next, in Fig. 7(c), with the movable shaft 403 inserted into the weapon member 401, the movable shaft 403 is further inserted into the weapon member 402 and fitted into the fastener 404 at the end. This completes the assembly of the weapon part 201a, as shown in Fig. 7(d). The weapon part 201b, which is the symmetrical one, is assembled in the same manner, and in Fig. 7(e), the movable shaft ends (spherical) of the weapon parts 201a and 201b are inserted into the base member 202, completing the assembly of the weapon 105.

[0033] As described above, the locking mechanism for the movable shaft in the part attached to the doll body according to this embodiment is a movable shaft that rotates a part of the part, and includes a movable shaft having a first restricting part that restricts the movable shaft from coming off the part when the movable shaft is rotated to a predetermined angle around the axial direction after being inserted into the part. Furthermore, this locking mechanism includes a fastener that locks the movable shaft inserted into the part and restricts the movement of the movable shaft in the rotational direction. This restricts the rotation and removal of the movable shaft that occurs when the part is rotated, and prevents the movable shaft from coming off the part.

[0034] <Modification> The present invention is not limited to the above-described embodiment, and various modifications and variations are possible within the scope of the gist of the invention. For example, in the above-described embodiment, the first and second restricting parts are provided separately on the movable shaft, but they may be provided integrally on the movable shaft. A modification of the locking mechanism will be described in detail with reference to FIG. 8. FIG. 8(a) shows a movable shaft 800 which is a modification, and FIG. 8(b) shows a fastener 810 which is a modification.

[0035] As shown in Fig. 8(a), movable shaft 800 includes shaft member 801 and end portions 802, 804. Furthermore, shaft member 801 has restricting portion 803 formed across multiple ribs, and extending from a predetermined rib to end portion 804. Meanwhile, as shown in Fig. 8(b), fastener 810 has fastener main body 811 provided with insertion portion 812, and insertion portion 812 has recess 813 formed therein.

[0036] The restricting portion 803 of the movable shaft 800 has both the function of the restricting portion 503 (first restricting portion) of the movable shaft 403 according to the above embodiment and the function of the slit (second restricting portion) 505. That is, when the restricting portion 803 is inserted into the weapon member 401, it passes through the groove 602 of the weapon member 401, and when it is rotated after insertion, it comes into contact with the restricting member 603 of the weapon member 401, thereby restricting the rotation beyond a predetermined angle. Also, when the restricting portion 803 is inserted into the fastener 810, it is inserted into the recess 813 thereof, thereby restricting the rotation of the movable shaft 800. This makes it possible to prevent the movable shaft 800 from coming off the weapon members 401, 402.

[0037] In this way, by providing the first and second restricting parts integrally on the movable shaft, in addition to the effects of the above embodiment, the restricting part 803 itself can be strengthened, and damage when a rotational force is applied can be reduced. Note that, although a modified example in which the first and second restricting parts are provided integrally has been described here, even when they are provided separately on the movable shaft as in the above embodiment, for example, the restricting part 503 according to the above embodiment may be provided across a plurality of ribs to ensure thickness and reduce damage when a rotational force is applied. Also, as in the above embodiment and this modified example, the convex part and the concave part that realize the function of the second restricting part may be provided on either the movable shaft or the fastener.

[0038] In the above embodiment, the movable shaft lock mechanism is applied to a weapon part of a doll toy. However, the present invention is not limited to this, and may be applied to any part or position as long as it is a rotatable part. For example, the movable shaft lock mechanism of the present invention may be applied to a movable shaft of a shoulder joint of a doll body. In this case, the left and right arms are rotatably attached to the shoulder joint, and a movable shaft is provided inside each arm and is rotatably inserted into the shoulder joint. The shape of the doll toy (doll body) is not particularly limited, and includes various shapes having a movable shaft, such as a person, an animal, a robot, a vehicle (train, car, airplane, etc.), and a dinosaur.
