Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a first member and a second member.
The present invention relates to a joint device for rotatably connecting the above members via a spherical joint.

[0002]

2. Description of the Related Art A conventional joint device 50 having a spherical joint.
As shown in FIGS. 7A and 7B, a first member 51 such as a trunk having a spherical joint 55 via a shaft member 53,
And a second member 52 such as a head on which a holding portion 56 for rotatably holding the spherical joint 55 is formed. The second member 52 is rotatably attached to the first member 51 by fitting the holding portion 56 of the second member 52 to the spherical joint 55 of the first member 51.

[0003]

The above-mentioned conventional joint device 5
0 indicates that the second member 52 can be inclined in the front-rear direction (X direction), in the left-right direction (Y direction), or rotated 360 degrees in the left-right direction (Z direction).
When the member 52 is tilted in the front-rear direction or the left-right direction, the shaft 5
There has been a problem that the peripheral edge 57 of the holding portion 56 is pressed against the third member 3 to damage the shaft member 53 or the holding portion 56 comes off from the spherical joint 55. In addition, since the second member 52 can make one rotation in the left-right direction, there is a problem that, for example, when the head is the head of a doll toy, the movement as the head is unnatural.

The present invention has been devised in view of the above-mentioned problems, and connects a first member and a second member so as to be movable in multiple directions by a spherical joint, while restricting the range of movement. It is an object of the present invention to provide a joint device having a novel structure which has been hardly broken and which has not been conventionally provided.

The joint device according to the first aspect has the following means to achieve the above object. (A) It is composed of a first member and a second member. (B) The first member is provided with a spherical joint via a shaft member. (C) The second member has a holding portion for rotatably holding the spherical joint of the first member. (D) At least one guide projection is formed on the spherical joint or the holding portion, and a guide concave portion is formed on the spherical joint or the holding portion where the guide projection is not formed to regulate the movable range of the guide projection. That

The joint device according to the second aspect has the following means to achieve the above object. (A) It is composed of a first member and a second member. (B) A spherical joint is provided above the first member via a shaft member. (C) A holding portion for rotatably holding the spherical joint of the first member is formed below the second member. (D) Guide projections are formed on the upper and front or rear portions of the spherical joint or the holding portion. (E) A guide recess is formed in the upper part and the front part or the rear part of the spherical joint or the holding part where the guide protrusion is not formed, which regulates the movable range of the guide protrusion.

According to a third aspect of the present invention, the first member is a body of the doll toy, and the second member is a head of the doll toy.

5 is formed in front and rear parts, and the front body 17 and the rear body 1
The front body 17 and the rear body 19 are joined together and are integrally assembled with the screws 9.

A hemispherical sliding contact surface 23 for slidingly contacting the spherical joint 5 is formed in a lower portion of the front member 17, and a front guide recess 21 is formed in the sliding contact surface 23. In addition, sliding contact surface 2
A semicircular concave portion 20a is formed in the upper portion of the slide contact surface 3, and a semicircular opening 25a is formed in the lower portion of the sliding contact surface. The front member 17
Alignment pins 26 are formed at the top, and screw holes 2
A boss 29 formed with 7 is protruded.

A hemispherical sliding contact surface 30 for slidingly contacting the spherical joint 5 is formed below the rear member 19, and a rear guide recess 22 is formed in the sliding contact surface 30. Also, the sliding surface 3
A semicircular concave portion 20b is formed in the upper part of the zero, and a semicircular opening 25b is formed in the lower part of the sliding contact surface 30. The rear member 19 is
An insertion hole 31 into which the positioning pin 26 of the front member 17 is inserted is formed in an upper portion, and a fitting hole 33 in which the boss 29 of the front member 17 is fitted and a screw through hole 32 is formed is provided on both sides. .

The second member 15 inserts the positioning pins 26 into the insertion holes 31 and the bosses 29, 29 into the fitting holes 33,
33, the front member 17 and the rear member 19 are joined, and the screws 9, 9 are passed through the screw holes 32, 32 and screwed into the screw holes 27, 27, thereby integrally assembling. Can be The semicircular recess 20a and the semicircular recess 20b are joined to each other to form the upper guide recess 20. The semicircular opening 25a and the semicircular opening 25b are joined to each other to form the opening 25. Tapers 20 c and 25 c are formed on the periphery of the upper guide recess 20 and the opening 25.

When the second member 15 is assembled as described above such that the spherical joint 5 of the first member 2 is sandwiched between the front member 17 and the rear member 19, the front guide projection 11 is After entering the guide recess 21, the upper guide protrusion 1
0 enters the upper guide recess 20 and the rear guide projection 12
Enters the rear guide recess 22, and the shaft member 3 passes through the opening 25.

The front guide projection 11 is provided in the front guide recess 2.
1 so that the upper guide protrusion 1
0 is regulated so that it can move only in the upper guide recess 20, and the rear guide protrusion 12 is regulated so that it can move only in the rear guide recess 22.

The joint device 1 has the above-described structure, and as shown in FIGS.
5 is rotated in the left-right direction (X direction), the front guide projection 11 contacts the side wall 21a of the front guide recess 21 and the rear guide projection 12 contacts the side wall 22a of the rear guide recess 22. The rotation range of the member 15 in the left-right direction (X direction) is regulated. The rotation range of the second member 15 in the left-right direction (X direction) is, of course, restricted even if one of the front guide protrusion 11 and the rear guide protrusion 12 is not provided.

As shown in FIGS. 2, 4 and 5, when the joint device 1 is inclined in the left-right direction (Y direction) or the front-back direction (Z direction) about the spherical joint 5, the upper guide projection 10 Abuts on the taper 20c of the upper guide recess 20, so that the tilting range of the second member 15 in the left-right direction (Y direction) and the front-back direction (Z direction) is restricted.

In the above embodiment, the first member 2 is the torso of the doll body, and the second member 15 is the head of the doll body. However, the present invention is not limited to this. For example, the second member may be an arm, a leg, or a tail. In addition, the guide protrusion is formed in the spherical joint and the guide recess is formed in the holding portion. Alternatively, the guide recess may be formed in the spherical joint and the guide protrusion may be formed in the holding portion.

[0021]

As described above, in the joint device according to the first and second aspects of the present invention, the guide projection and the guide are respectively provided on the spherical joint and the holding portion for freely connecting the first member and the second member. Since the concave portion is formed, the movable range of the guide protrusion is regulated by the guide concave portion, and the movable range of the first member and the second member is determined. Therefore, there is an effect that the peripheral edge of the holding portion is pressed against the shaft member to which the spherical joint is attached, so that the shaft member is not damaged and the holding portion does not come off from the spherical joint.

In the joint device according to the third aspect of the present invention, in addition to the above-described effects, the first member is the trunk of the doll toy and the second member is the head of the doll toy. There is an effect that the movement range of the second member is restricted, and the movement of the second member can be made similar to that of the real head.
