Description

  The present invention relates to a joint structure of a doll toy.

  The arms and legs of the doll toy are rotatably attached to the body part in order to enable movement close to a human.

  In this case, the movement range closer to the human can be realized by expanding the rotation range of the arm and the leg with respect to the body part.

  As a technique related to the present invention, for example, a joint structure of a doll disclosed in Patent Document 1 below is known. Patent Document 1 includes a first member and a second member that are coupled via a joint member, and the joint member includes a first shaft portion that fits into a first fitting hole provided in the first member, and A second shaft portion that fits into a second fitting hole provided in the second member, and a pivot portion that rotatably supports the first shaft portion and the second shaft portion. Even after the first member abuts against the second member by rotating the first member relative to the second member by allowing the one shaft portion to slide within the first fitting hole, It is described that the first shaft portion can be moved in the direction of pulling out from the first fitting hole by the lever action as a fulcrum, thereby further rotating the first member.

Japanese Patent No. 4918154

  However, in the technique shown in Patent Document 1, in the first member and the second member that are connected via the joint structure, the opening angle between the first member and the second member centering on the joint structure is, for example, The rotatable range can be expanded to be 90 ° or more.

  For this reason, even if the opening angle of the first member and the second member is increased, the movement of the first member and the second member is the movement in the plane including the first member and the second member. Therefore, there is a disadvantage that the degree of freedom of rotation is low.

  This invention is made | formed in view of such a situation, The objective is the other member with respect to one member (1st member), maintaining intensity | strength in each member attached via a joint mechanism. An object of the present invention is to provide a joint structure of a doll toy that can increase the degree of freedom in rotation of the (second member) with a simple structure.

In order to achieve such an object, according to the present invention, in the joint structure interposed between the first member and the second member, at least the peripheral surface provided at the tip of the shaft projecting from the first member is a spherical surface. The abutting portion is slidably inserted into a cylindrical hole formed in the second member, and the shaft body has a diameter A smaller than the inner diameter of the cylindrical hole formed on the first member side. A first shaft body having a first shaft body and a second shaft body formed on the corresponding contact side and having a diameter B (A> B), and on the contact portion side of the first shaft body The end surface is formed so as to be inclined with respect to the central axis of the first shaft body, and the end portion is configured to reach the vicinity of the contact portion.
As a result, the second member can be rotated around the central axis of the cylindrical hole and can be rotated so that the central axis of the cylindrical hole and the central axis of the first shaft body form an angle. Therefore, the freedom degree in rotation of the 2nd member with respect to the 1st member can be made higher.

  The present invention is grasped by the following composition.

The joint structure of the doll toy according to the present invention includes a first member that is a part of the body of the doll toy, a second member that is a part of the body of the doll toy, and the first member and the second member. A joint structure of a doll toy comprising: a contact portion provided at a tip of a shaft projecting from the first member and having a spherical surface at least on a peripheral surface thereof Is slidably inserted into a cylindrical hole formed in the second member, and the shaft body is formed on the first member side and has a diameter A smaller than the inner diameter of the cylindrical hole. A first shaft body and a second shaft body formed on the contact portion side and having a diameter B (A> B), and the end surface of the first shaft body on the contact portion side is the first shaft The second member is formed so as to be inclined with respect to the central axis of the body, and an end thereof reaches the vicinity of the contact portion. Characterized in that the central axis of the first shaft with the center axis of the cylindrical holes is configured so as to rotate at an angle. The joint structure of the doll toy according to the present invention includes a first member that is a part of the body of the doll toy, a second member that is a part of the body of the doll toy, the first member, and the second member. A joint structure of a doll toy comprising a joint mechanism formed between the first and second joints, wherein at least a peripheral surface provided at a tip of a shaft projecting from the first member is a spherical surface. The contact portion is configured by being slidably inserted into a cylindrical hole formed in the second member, the contact portion is a sphere, and the shaft is formed on the first member side. A first shaft body having a diameter A smaller than the inner diameter of the cylindrical hole and substantially equal to the contact portion; and a second shaft body formed on the contact portion side and having a diameter B (A> B). The end surface of the first shaft body on the contact portion side is formed so as to be inclined with respect to the central axis of the first shaft body. The end portion of the shaft reinforces the shaft body by reaching the contact portion, and the second member is positioned relative to the first member from a position where the cylindrical hole includes the first shaft body.

  According to the joint structure of the doll toy thus configured, in each member attached via the joint mechanism, the rotation of the other member (second member) relative to one member (first member) is maintained while maintaining the strength. The degree of freedom in movement can be increased with a simple structure.

It is a perspective view which shows Example 1 of the joint structure of the doll toy of this invention. (A), (b) has shown sectional drawing at the time of attaching the 2nd member to the 1st member via the joint mechanism. It is sectional drawing which shows the other Example of the joint structure of the doll toy of this invention.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. Note that the same numbers are assigned to the same elements throughout the description of the embodiments.

  FIG. 1 is a perspective view showing Example 1 of the joint structure of the doll toy of the present invention. In FIG. 1, there is a first member 10 that becomes a body portion of a doll, for example, and there is a second member 20 that becomes an arm portion attached to the first member 10. A joint mechanism 30 is formed between the first member 10 and the second member 20, and the joint mechanism 30 allows the second member 20 to rotate in the direction described later with respect to the first member 10. ing.

  In the joint mechanism 30, a sphere 32 (contact portion according to the present invention) provided at the tip of the shaft body 31 protruding from the first member 10 is slidable in a cylindrical hole 35 formed in the second member 20. It is configured by being inserted.

  Here, the shaft body 31 is configured by integrating a first shaft body 31A and a second shaft body 31B having different diameters along the axial direction. In the present embodiment, the first shaft body 31A is formed on the first member 10 side to have a diameter substantially equal to that of the sphere body 32, and the second shaft body 31B is formed on the sphere body 32 side. Is formed with a smaller diameter. That is, if the diameter on the first shaft body 31A side is A and the diameter on the second shaft body 31B side is B, then A> B. In the present embodiment, the axis of the second shaft body 31B is shifted from the axis of the first shaft body 31B. More specifically, the peripheral surface of the second shaft body 31B is the first shaft body 31A. It is shifted so that it touches the surrounding surface. Now, the end surface of the first shaft body 31A on the sphere 32 side is formed so as to have a slope 37 with respect to the central axis of the first shaft body 31A. That is, the end surface of the first shaft body 31A on the sphere 32 side is formed to be inclined with respect to the central axis of the first shaft body 31A. Further, the inclined surface 37 of the first shaft body 31A is, for example, as shown in FIG. 1, from a position close to the first member 10 above the first member 10 in FIG. As it goes, it goes to a place away from the first member 10 and reaches the vicinity of the sphere 32 (up to the sphere 32 in this embodiment). That is, the end surface of the first shaft body 31 </ b> A on the sphere 32 side reaches the vicinity of the sphere 32.

  FIGS. 2A and 2B are cross-sectional views when the second member 20 is attached to the first member 10 via the joint mechanism 30.

  2A, the second member 20 is attached to the first member 10 such that the cylindrical hole 35 includes not only the sphere 32 of the first member 10 but also the first shaft 31A. It is the figure which showed the case. In this case, the second member 20 can be rotated around the central axis 38 of the cylindrical hole 35 (in the direction of arrow α in the figure). That is, when the second member 20 is an arm, for example, the arm can be operated to rotate in the front-rear direction.

  2B shows the second member 20 in the direction in which the central axis 38 of the cylindrical hole 35 and the central axis 39 of the first shaft 31A form an angle γ (the center of the sphere 32 is the center of rotation. When the second member 20 is an arm, for example, the tip is moved away from the first member 10 serving as the body part to the side. FIG. In order to rotate the second member 20 in the direction of the arrow β, first, at least the peripheral edge (indicated by P in the drawing) of the cylindrical hole 35 can be brought into contact with the inclined surface 37 of the first shaft body 31A. The first member 10 is separated from the first member 10 along the axial direction of the shaft body 31 until the position exceeds the first position. Thereafter, when the second member 20 is rotated in the direction of arrow β, there is a difference between the diameter A of the first shaft body 31A and the diameter B of the second shaft body 31B. The central shaft 39 of the shaft body 31A can be rotated so as to form an angle γ. When the second member 20 is rotated in the direction of the arrow β, if the peripheral edge (P in the figure) of the cylindrical hole 35 abuts on the inclined surface 37, the peripheral edge moves so as to slide on the inclined surface 37. Therefore, the rotation of the second member 20 is not hindered. Since it is as above, when the 2nd member 20 is an arm, for example, the front-end | tip can be moved away from the 1st member 10 used as a trunk | drum. In this case, needless to say, the second member 20 can also rotate around the central axis 38 of the cylindrical hole 35 (in the direction of arrow α in the figure).

  The above-described rotation of the second member 20 relative to the first member 10 can be performed even when the shaft body 31 is only the second shaft body 31B and the first shaft body 31A is not formed. The strength is weakened. If the diameter of the second shaft body 31B is increased in order to maintain the strength of the shaft body 31, the peripheral edge of the cylindrical hole 35 can be immediately seen when the second member 20 is rotated in the direction of arrow β in FIG. The second shaft body 31B comes into contact with the first member 10, and the angle (rotation range) at which the second member 20 can rotate with respect to the first member 10 becomes narrow. Therefore, the present invention provides the first shaft body 31A having a diameter larger than that of the second shaft body 31B, thereby strengthening the strength of the shaft body 31 and increasing the diameter of the first shaft body 31A and the second shaft body 31B. Due to the difference in diameter, an angle (rotation range) in which the second member 20 can be rotated can be obtained. Further, the end surface of the first shaft body 31A on the sphere 32 side is formed so as to be inclined with respect to the central axis 39 of the first shaft body 31A, and the end portion reaches the vicinity of the sphere body 32. The single shaft body 31 </ b> A can reinforce the entire shaft body 31 while securing an angle (rotation range) at which the second member 20 can rotate. As described above, according to the present invention, the degree of freedom in rotation of the second member 20 relative to the first member 10 can be increased with a simple structure while maintaining strength.

  Further, in the present embodiment, there is also an effect that the inclined surface 37 formed on the first shaft body 31A serves as a guide, and the second member 20 can be rotated around the joint mechanism 360 with an accurate trajectory. Yes.

  In the first embodiment, the cylindrical hole 35 formed in the second member 20 is provided by forming a hole on the flat side surface of the second member 20. However, the present invention is not limited to this. For example, as shown in FIG. 3, a cylindrical member 40 is formed on the flat side surface of the second member 20, and a space surrounded by the cylindrical member 40 functions as a cylindrical hole 35. You may make it make it.

  In Example 1, although the case where the 1st member 10 was used as the trunk | drum and the 2nd member 20 was comprised as an arm part was shown, it is not limited to this, In the other joint part of a doll, it is mentioned above. The configuration described above may be adopted. In this case, the direction in which the second member 20 is rotated can be determined according to the direction in which the inclined surface 37 of the first shaft body 31A in the joint mechanism 30 is directed.

  As mentioned above, although this invention was demonstrated using the Example, it cannot be overemphasized that the technical scope of this invention is not limited to the range as described in the said Example. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above-described embodiments. Further, it is apparent from the description of the scope of claims that embodiments with such changes or improvements can also be included in the technical scope of the present invention.
