Description

The present invention relates to a movable shaft locking mechanism, a movable shaft, and a doll toy in parts attached to the doll toy.

In doll toys, there are parts that can be rotatably attached around a predetermined movable axis. When such a component is rotated, a force (tension) is generated in a direction opposite to the direction in which the movable shaft is inserted into the component. This force in the opposite direction is a force that acts to cause the movable shaft to come out of the component. Therefore, it is necessary to prevent the movable shaft from coming off due to the force in the opposite direction that may occur when the component is rotated.

Patent Document 1 proposes an assembled toy having a mechanism for locking each component by rotating a support member including a rod-shaped body inserted into each through hole of the plurality of components around an axis.

Japanese Unexamined Patent Publication No. 2012-148172

However, in the above-mentioned prior art, 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 rotational direction of the axis center is applied to the support member. .. That is, when a force in the rotational direction is applied to the support member, the support member may come off (separate) from each component and rotate back to the position at the time of insertion. In such a configuration, for example, in a part rotatably attached such as a weapon mounted on a doll body, there is a possibility that the movable shaft is frequently detached.

The present invention provides, for example, a locking mechanism that prevents detachment of a movable shaft of a component that is rotatably attached to a doll body.

The present invention is a movable shaft locking mechanism for a part mounted on a doll body, which is a movable shaft that rotates a part of the part, and has a predetermined angle about an axial direction after being inserted into the part. When rotated to, the movable shaft having the first regulating portion that regulates the removal from the component and the movable shaft inserted into the component are locked to regulate the movement of the movable shaft in the rotational direction. It is characterized by being equipped with ingredients.

Further, the present invention is a movable shaft of a component mounted on a doll body, and when the component is inserted into the component and then rotated to a predetermined angle about the axial direction, the first invention restricts the component from coming off the component. It is characterized by including a regulating portion and a second regulating portion that regulates the movement of the movable shaft in the rotational direction when inserted into the fastener.

According to the present invention, it is possible to prevent the movable shaft of the component rotatably attached to the doll body from coming off.

It should be noted 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 of the plurality of features described in the embodiments may be arbitrarily combined. In addition, the same or similar configuration will be given the same reference number, and duplicated explanations will be omitted.

<Appearance of doll toys>
First, with reference to FIGS. 1 and 2, an example of the appearance configuration of the doll toy to which the rotatable parts according to the present embodiment are mounted will be described. FIG. 1 shows the front view of the appearance of the doll toy 100, and FIG. 2 shows the back view of the appearance of the doll toy 100. Although an example of mounting a rotatable part on a doll toy will be described here, there is no intention of limiting the present invention. In short, it may be an article to which a rotatable part can be attached. Further, although a weapon is described as an example as a rotatable component, there is no intention of limiting the present invention to the type, mounting position, etc. of the weapon. Any part having a movable shaft (rotating shaft) like the rotatable part of the present invention described below may be used, and can be applied to, for example, the shoulder joint of a doll body in a doll toy. In this case, the arm portion attached to the shoulder joint operates rotatably.

The doll toy 100 includes a doll body composed of a head 101, a body portion 102, an arm portion 103, and a leg portion 104, and a weapon 105 attached to the doll body. The head 101 is attached to the body portion 102 and is located in the area shown by the dotted line in FIG. The body portion 102 is further attached with an arm portion 103 including a right arm and a left arm, and a leg portion 104 including a right foot and a left foot. The weapon 105 is a component attached to the doll body, and as shown in FIG. 2, in the present embodiment, the weapon 105 is attached from the back to the shoulder of the doll body. A part of the weapon 105 is rotatably attached to the doll body. In the present embodiment, the weapon 105 is attached and fixed on the back of the doll body, and a part (cylindrical part) of the weapon 105 located at the upper part of both shoulders can be rotated.

<Structure of weapons (parts)>
Next, with reference to FIG. 3, the configuration of the weapon 105, which is a rotatable part (part) according to the present embodiment, will be described. FIG. 3A is an enlarged rear view of the weapon 105, and FIG. 3B is an enlarged side view of the weapon 105.

The weapon 105 includes weapon portions 201a and 201b, a foundation member 202, and a mounting member 203. The weapon units 201a and 201b are symmetrically configured, respectively. The detailed configuration of each weapon unit 201a and 201b will be described later with reference to FIG. The weapon portions 201a and 201b are individually rotatably attached to the foundation member 202.

As shown in FIG. 3B, the mounting member 203 is inserted into the body portion 102 to fix the weapon 105 to the doll body and mount it. The weapon units 201a and 201b attached to the doll body can rotate about the respective rotation axes 204 in the arrow direction 210. The state when it is rotated is shown by the dotted line 211. In this way, the weapon portions 201a and 201b, which are a part of the weapon 105, are rotatable, respectively, and at the time of rotation, a force is applied to the direction in which the weapon portions 201a and 201b are pulled out and the rotation direction, respectively. These forces may be applied to the movable shafts of the weapon portions 201a and 201b, which will be described later, that is, they may act to separate the movable shafts from the respective weapon members. Therefore, the rotatable component according to the present embodiment is provided with a lock mechanism for preventing the movable shaft from being detached.

<Detailed configuration of weapons (parts)>
Next, with reference to FIG. 4, a detailed configuration of the weapon 105, which is a rotatable component according to the present embodiment, will be described. FIG. 4A is an exploded view of the weapon 105, and FIG. 4B is an exploded view of the weapon portion 201a.

As shown in FIG. 4A, the weapon portions 201a and 201b are rotatably attached to the foundation member 202 by inserting a spherical portion which is one end of a movable shaft. The weapon units 201a and 201b have a symmetrical configuration as shown in the figure, and the basic configuration is the same. Therefore, in the following, the weapon unit 201a will be described as an example as a detailed configuration of the weapon unit.

As shown in FIG. 4B, the weapon unit 201a includes weapon members 401, 402, a movable shaft 403, and a fastener 404. The movable shaft 403 is inserted into the weapon member 401, rotated 180 degrees, and then inserted into the weapon member 402. Further, the fastener 404 is inserted into the weapon member 402 from the direction opposite to the movable shaft 403 to lock the movable shaft 403 and fix its rotation.

<Structure of movable shaft and fastener>
Next, with reference to FIG. 5, the configuration of the movable shaft 403 and the fastener 404 according to the present embodiment will be described. FIG. 5A shows the configuration of the movable shaft 403, and FIG. 5B shows the configuration of the fastener 404.

First, the configuration of the movable shaft 403 will be described. The movable shaft 403 includes a shaft member 501 and ends 502 and 504. As shown in FIG. 5A, the shaft member 501 has a rib structure composed of a plurality of ribs, and has a regulation portion 503 and a regulation plate 506. The regulating portion 503 is formed as a part of a predetermined rib and is formed higher than other parts of the predetermined rib and other ribs. It should be noted that there is no intention of limiting the present invention, and the invention may be formed over a plurality of ribs, for example. As a result, the thickness of the regulating portion 503 is increased, and the strength of the member can be further strengthened. Further, a rib higher than the rib corresponding to the regulation portion 503 may be formed, or a plurality of ribs may not be provided on the movable shaft 403 and only the regulation portion 503 may be formed. Further, the shape and arrangement of the rib corresponding to the regulation portion 503 is not particularly limited, and may be any one that can regulate the removal from the weapon member 401.

The regulation unit (first regulation unit) 503 is a portion for restricting the rotation of the movable shaft 403 beyond a predetermined angle (180 degrees in the present embodiment) after being inserted into the weapon member 401. Further rotation is restricted by the restricting unit 503 being caught by the restricting member provided on the weapon member 401, which will be described later. 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 further inserted into the weapon member 401 by abutting on the outer wall of the insertion hole. It is a thing.

The end portion 502 is formed in a spherical shape and is a portion to be inserted into the base member 202 after the weapon portion 201a is assembled. Since it has a spherical shape after insertion, it can rotate within the space of the foundation member 202, which is the member to be inserted. Further, the spherical shape of the end portion 502 is formed to be slightly larger than the diameter of the insertion port of the base member 202, but since the doll toy 100 is made of an elastic member such as plastic, it bends when it is inserted. Therefore, the diameter can be widened and inserted. Therefore, after the insertion, the mechanism is such that the weapon portion 201a cannot be pulled out with a force sufficient to rotate and use it. As described above, although the movable shaft 403 is configured so as not to be pulled out by a force within a predetermined range by being inserted into the foundation member 202, when the weapon portion 201a is rotated and used, as described above. There is also the possibility that the weapon members 401 and 402 will come off. The details of the locking mechanism for preventing the movable shaft 403 from coming off from the weapon members 401 and 402 will be described later with reference to FIG.

The end portion 504 has a slit (notch) 505 formed in a concave shape. The slit 505 restricts the rotation of the movable shaft 403 by inserting the convex portion 513 described later of the fastener 404. Therefore, the slit 505 is an example of the second regulating unit that regulates the rotation of the movable shaft 403 about the axial direction.

Subsequently, the configuration of the fastener 404 will be described. The fastener 404 is provided with an insertion portion 512 into which the movable shaft 403 is inserted into a part of the fastener main body 511. Further, the insertion portion 512 is formed with a convex portion 513 that is inserted into the slit 505 of the movable shaft 403. By inserting the convex portion 513 into the slit 505 which is a concave portion, it is possible to regulate the rotation of the movable shaft 403 about the axial direction.

<Lock mechanism>
Next, the locking mechanism of the movable shaft 403 according to the present embodiment will be described with reference to FIG. The lock mechanism according to the present embodiment is centered on a first regulating unit that regulates the removal of the movable shaft 403 from a tension applied in a direction opposite to the direction in which the movable shaft 403 is inserted into the weapon member 401, and an axial direction of the movable shaft 403. It is composed of a second regulation part that regulates the rotation. FIG. 6A shows the functional configuration of the first regulatory unit, and FIG. 6B shows the functional configuration of the second regulatory unit.

First, the functional configuration of the first regulatory unit will be described. FIG. 6A shows a state in which the movable shaft 403 is inserted into the weapon member 401 and rotated 180 degrees in the direction of arrow 604. The weapon member 401 is provided with an insertion hole 601 for receiving the movable shaft 403. The insertion hole 601 is formed with a groove 602 through which the restricting portion 503, which is a part of a predetermined rib of the movable shaft 403, passes through. Therefore, when the movable shaft 403 is inserted, the regulating portion 503 passes through the groove 602. After insertion, that is, in a state where the regulation plate 506 of the movable shaft 403 abuts on the outer wall of the insertion hole 601 of the weapon member 401 and cannot be further inserted, the movable shaft 403 is rotated in the direction of the arrow 604. When rotated to a predetermined angle, the regulating portion 503 comes into contact with the regulating member 603 provided on the weapon member 401, and further rotation is restricted. In such a post-rotation state, the regulating portion 503 moves from the groove 602 passed at the time of insertion to a position facing the insertion hole 601 across the insertion hole 601. Therefore, in this state, the restricting portion 503 cannot pass through the groove 602, and even if the above tension is applied, the restricting portion 503 abuts on the inner wall of the weapon member 401 to restrict the movable shaft 403 from coming off. be able to.

Next, the functional configuration of the second regulatory unit will be described. FIG. 6B shows how the movable shaft 403 is inserted into the fastener 404. For the sake of simplicity, as shown in FIG. 4B, the weapon members 401 and 402 exist between the movable shaft 403 and the fastener 404, but they are omitted. .. Further, the movable shaft 403 is shown in a state of being rotated by 180 degrees as described with reference to FIG. 6A. 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 in 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, that is, the rotation of the movable shaft 403 causes the restricting portion 503 to rotate back to the position of the groove 602, and the movable shaft 403 returns. It is possible to prevent the weapon member from coming off the member 401.

As described above, the lock mechanism of the movable shaft according to the present embodiment is regulated in two stages (regulation by the first regulation section and the second regulation section). As a result, while the movable shaft 403 can be easily assembled, the tension and rotational force applied to the movable shaft 403 after assembly can be suppressed, and the movable shaft 403 can be suitably prevented from coming off from the weapon members 401 and 402.

<Assembly process>
Next, the assembly process of the weapon 105 according to the present embodiment will be described with reference to FIG. 7. The assembly process is performed in the order of the arrows, that is, (a), (b), (c), (d), and (e) are assembled in this order.

First, in FIG. 7A, 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, until the regulating plate 506 abuts on the outer wall of the insertion hole 601 of the weapon member 401, FIG. 7 (b). ), The movable shaft 403 is rotated in the direction of the arrow 604. Although an example of rotating 180 degrees is described here, there is no intention of limiting the present invention, and the angle may be any angle at which the regulating portion 503 is rotated to a position ten separated from the groove 602.

Next, in FIG. 7C, with the movable shaft 403 inserted into the weapon member 401, the movable shaft 403 is further inserted into the weapon member 402 and inserted into the fastener 404 beyond that. As a result, as shown in FIG. 7D, the assembly of the weapon portion 201a is completed. The weapon portion 201b, which is one of the symmetrical parts, is also assembled in the same manner. The assembly of 105 is completed.

As described above, the lock mechanism of the movable shaft in the part mounted on the doll body according to the present embodiment is a movable shaft that rotates a part of the part, and is centered in the axial direction after being inserted into the part. It is provided with a movable shaft having a first regulating portion that regulates the part from coming off when rotated to a predetermined angle. Further, the lock mechanism includes a fastener that locks the movable shaft inserted in the component and regulates the movement of the movable shaft in the rotational direction. As a result, it is possible to regulate the rotation and disconnection of the movable shaft that occurs when the component is rotated, and prevent the movable shaft from being detached from the component.

<Modification example>
The present invention is not limited to the above embodiment, and various modifications and changes can be made within the scope of the gist of the invention. For example, in the lock mechanism of the movable shaft in the above embodiment, the first regulating portion and the second regulating portion are individually provided on the movable shaft, but they may be integrally provided on the movable shaft. A modified example of the locking mechanism will be described in detail with reference to FIG. FIG. 8A shows a movable shaft 800 as a modified example, and FIG. 8B shows a fastener 810 as a modified example.

As shown in FIG. 8A, the movable shaft 800 includes a shaft member 801 and ends 802 and 804. Further, the shaft member 801 is formed by having a regulating portion 803 extending over a plurality of ribs and extending from a predetermined rib to an end portion 804. On the other hand, as shown in FIG. 8B, the fastener 810 is provided with an insertion portion 812 in the fastener main body 811 and a recess 813 is formed in the insertion portion 812.

The regulation unit 803 of the movable shaft 800 has both the functions of the regulation unit 503 (first regulation unit) and the slit (second regulation unit) 505 of the movable shaft 403 according to the above embodiment. That is, the restricting unit 803 is inserted through the groove 602 of the weapon member 401 when inserted into the weapon member 401, and abuts on the restricting member 603 of the weapon member 401 during rotation after insertion, thereby exceeding a predetermined angle. It is possible to regulate the rotation. Further, when the regulating portion 803 is inserted into the fastener 810, it is inserted into the recess 813 to regulate the rotation of the movable shaft 800. This makes it possible to prevent the movable shaft 800 from being detached from the weapon members 401 and 402.

In this way, by providing the movable shaft integrally with the first regulation portion and the second regulation portion, in addition to the effect of the above embodiment, the regulation portion 803 itself can be further strengthened, and a rotational force is applied. It is possible to reduce the damage at the time. Here, a modified example in which the first regulation unit and the second regulation unit are integrally provided has been described, but even when the first regulation unit and the second regulation unit are individually provided on the movable shaft as in the above embodiment, for example, the above implementation The thickness may be secured by providing the regulation portion 503 according to the form over a plurality of ribs, and damage when a rotational force is applied may be reduced. Further, as in the above embodiment and the present modification, the convex portion and the concave portion that realize the function of the second regulating portion may be provided on either the movable shaft or the fastener, respectively.

Further, in the above embodiment, an example in which the lock mechanism of the movable shaft is applied to the weapon parts of the doll toy has been described. However, the present invention is not limited to this, and may be applied to any component or position as long as it is a rotatable component. For example, the movable shaft locking mechanism of the present invention may be applied to the movable shaft of the shoulder joint of the 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 portion and is rotatably inserted into the shoulder joint.
