[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a joint mechanism in a toy having a movable joint, such as a robot toy, an animal toy, and a doll toy.

[0002]

[Prior art]

 Many conventional toys of this type are configured so that the joints move to achieve realism. Among them, using the magnetic force of the magnet, a magnet is provided on one member constituting the joint, a magnetized body such as iron is provided on the other member, and the magnetized body is attracted by the magnet, and the magnetized magnetic force is applied. It is known that the two members are connected so that they can move freely.

[0003]

[Problems to be solved by the invention]

 However, the articulated mechanism having such a structure has the merit that the object to be magnetized is formed in a spherical shape and one of the members constituting the articulated portion can be bent in any direction by 360 °. In addition to this, the magnetic force weakens and the coupling force decreases, and the two members that make up the joint are susceptible to the gravity of the toy. If the whole is heavy or only one is extremely heavy, the position It is difficult to maintain the angle and angle, and it is easy to drop without determining the pose. For example, if the load above the torso is large, the connection between the waist and both legs that make up the hip joint will not be maintained, and the torso will be easily determined depending on whether the center of gravity of the upper half is in front or behind. I fall forward or backward, and the pose cannot be determined. The same applies when the load on the right or left of the body is too large compared to the other.

The present invention solves the above-mentioned drawbacks, and provides a joint mechanism in a toy that can hold two members constituting a joint at a predetermined position or angle even if the magnetic force of the magnet is weakened. That is the subject.

[Embodiment of the invention]

 FIG. 1 is a perspective view of a robot toy. The robot toy is composed of a body 1, a head 2, an arm 3, and a leg 4, and a body 1, a head 2, both arms 3, and both legs 4. Are provided with joints, respectively, so that the head 2, the arms 3 and the legs 4 can move. The torso part 1 is composed of a torso main part 1a and a waist part 5, and a hip joint mechanism is provided between the waist part 5 and the leg part 4.

Therefore, the hip joint mechanism will be described with reference to FIG. 2. The hip joint is constituted by a waist 5, a leg 4, and an auxiliary member 6 used as needed. The waist 5 and the leg 4 have facing portions 7 and 8 facing each other in the joint.

The facing portion 7 of the waist portion 5 is formed in a cylindrical shape, and a magnet 21 faces inside. The end face of the facing portion 7 is circular, and four protrusions 9 (engaging portions) are formed at regular intervals so as to protrude in the radial direction, and a groove 10 is formed at the center of each protrusion 9. ing.

A spherical magnetic body 11 protrudes from the facing portion 8 of the leg 4. The outer diameter of the magnetized body 11 is formed slightly smaller than the inner diameter of the facing portion 8 of the waist portion 5. Further, two projecting portions 12 are formed on the facing portion 8, and a V-shaped engaging projecting portion 13 (engaging portion) is formed at the center of each projecting portion 12.

Next, the auxiliary member 6 is formed in an annular shape, and has an inner diameter substantially equal to the outer diameter of the facing portion 6 of the waist portion 5. Engaging portions 14 and 15 are formed on both sides of the auxiliary member 6 to engage with the two facing portions 7 and 8, respectively.

That is, two steps 16, 17 are formed on one end surface of the auxiliary member 6, and four engaging recesses 18 are formed at regular intervals on the outer step 16. At the center of each engagement recess 18, a projection 19 is formed continuously over the inner peripheral step 17. The engaging concave portion 18 and the convex portion 9 of the waist portion 5 are engaged with each other, and the projecting portion 19 is formed to have a size capable of engaging with the groove 10 of the convex portion 9.

On the other end surface of the auxiliary member 6, a concave groove 15 (engaging portion) is formed continuously on its circumference. The concave groove 15 is formed in a size that can be engaged with the engaging projection 13 formed on the facing portion 8 of the leg 4.

According to the above configuration, as shown in FIG. 3, the joint portion first fits the magnetized body 10 of the leg portion 4 inside the facing portion 7 of the waist portion 5 and the magnet disposed inside the facing portion 7. 21. The connection between the waist 5 and the leg 4 is maintained by the magnetic force of the magnet 21.

On the other hand, as shown in FIG. 1, attaching the weapon-like part 22 to one arm 3 changes the center of gravity of the upper half and increases the load of the upper half. When the magnetic force of the magnet 21 deteriorates over time, the connecting portion is reinforced through the auxiliary member 6. That is, as shown in FIGS. 2 and 4, first, the outer peripheral step portion of the auxiliary member 6 is fitted to the facing portion 7 of the waist portion 5, and the engaging concave portion 18 of the auxiliary member 6 is fitted to the convex portion 9 of the facing portion 7. And the projection 19 of the auxiliary member 6 is engaged with the groove 10 of the facing portion 7. Next, the magnetized body 10 of the leg portion 4 is fitted inside the facing portion 7 of the waist portion 5 to be attracted to the magnet 21, and the engaging projection 13 of the facing portion 8 of the leg portion 4 is attached to the auxiliary member. 6 is engaged with the concave groove 15. As a result, the auxiliary member 6 engages with the facing portion 7 of the waist portion 5 and also with the facing portion 8 of the leg portion 4, so that the position and angle of the leg portion 4 are reliably maintained. To change the angle of the leg 4, the engagement between the engaging projection 13 and the groove 15 may be changed by turning the leg 4. In this case, by continuously forming the concave groove 15 around one side surface of the auxiliary member 6, the angle can be finely adjusted. In addition, when the leg 4 is rotated, there is a click feeling. The operation is comfortable.

The joint mechanism is not unique to the waist joint between the waist 5 and the leg 4. For example, the present invention can be applied to a joint between the body 1 and the arm 3 or the head 2.

Further, the manner of engagement between the two members constituting the joint and the auxiliary member is not limited to the above example. Other configurations may be used as long as they can engage with each other.

Further, the auxiliary member 6 does not necessarily have to be annular. For example, it may be a polygon such as a quadrangle or a hexagon.

[0021]

[Actions and effects of the invention]

 According to the first aspect of the present invention, the joint is usually formed by connecting the magnet of one member to the magnetized object of the other member by suction. If the load and the angle of the two members cannot be maintained due to a large load applied to the joint, an auxiliary member may be interposed between the two members. Engaging portions are formed on both end surfaces of the auxiliary member to be engaged with the facing portions of the two members constituting the joint portion, respectively. The position and angle of the three members can be reliably maintained.

According to the second aspect of the present invention, the auxiliary member is formed in a ring shape, and the engagement portions are formed on both end surfaces thereof. Since the body can be housed inside and engaged with the facing portions of the two members, the appearance can be made natural.

According to the third aspect of the present invention, since the engagement portion on one side end surface of the auxiliary member is formed by a groove continuously formed on the circumference of the end surface, it forms a joint. In addition to being able to fine-tune the angle of the component, the operation is comfortable because there is a click when rotating the component.

According to the invention of claim 4, since the part of the auxiliary member is fitted to at least one of the facing portions, the engagement state becomes stronger.
