DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swinging device for operating an arm member in a robot toy or the like.

[0002]

2. Description of the Related Art Generally, an arm member such as a robot toy is known to have a structure in which it rotates with respect to a body portion. Recently, there has been a demand for something that can be developed into a game, rather than just moving and playing. For that purpose, an arm whose movement is changed is desired.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above background, and has a simple structure in which an arm portion is provided from a shoulder provided on a body portion so that an opposing robot or the like can hit by boxing. An object of the present invention is to provide an arm member swinging device that swings at an arbitrary angle.

[0004]

Means for Achieving the Object As a means for achieving the above object, a swinging device for an arm portion such as a robot toy according to the present invention is provided so that a body portion can be rotated with respect to a waist portion.
At the same time, shoulder members are rotatably connected to both sides of the body.
In addition, the present invention is characterized in that the following requirements for rotatably connecting the arm member to the shoulder member are provided. (A) The arm member is rotatably connected around a support shaft orthogonal to the center of rotation of the shoulder member. (B) The inside of the body portion is interlocked with the rotation of the body portion. An operating shaft that operates left and right and a drive mechanism that drives the operating shaft are provided. (C) Both ends of the operating shaft pass through the center of the connecting portion between the body and the shoulder member. (D) the connecting member is rotatably attached to the operating shaft and is connected to the arm member via a connecting member. (E) an operation shaft for operating the drive mechanism is provided on the waist portion via a connection shaft provided in a direction orthogonal to the axis of the shaft ;
It is provided to protrude outward, and interlocks with the rotation operation of the operation shaft.
The body part rotates

[0005]

According to the above construction, the operation of rotating the operation shaft can be performed.
Therefore, the torso part rotates and is provided inside the torso.
The actuated drive mechanism operates to move the operating shaft left and right. The connection member and the base of the arm member operate in the same direction in conjunction with the operation of the operation shaft, whereas the arm member is connected to the shoulder member by the support shaft, so this portion is in the same direction as the base. Can not move. For this reason, the arm member reciprocates around the support shaft connected to the shoulder member. Therefore, as a whole, the arm member swings left and right while rotating the body portion left and right.

Further, since both ends of the operating shaft pass through the center of the connecting portion between the body portion and the shoulder member, the shoulder member rotatably connected to the body portion by the connecting portion is rotated with respect to the body portion. However, the relationship between the arm member, the connecting member, and the operating shaft with respect to the shoulder member is constant. Therefore, when the operating shaft is operated regardless of the angles at which the left and right shoulder members are rotated, the arm can be swung at the rotated position of the shoulder members.

Next, as shown in FIG. 4, when the operating shaft 15 moves to the left, the connecting member 32 moves to the left together with the operating shaft 15.
Since the connecting shaft 33 formed in the connecting member 32 is loosely fitted in the engaging hole (13) formed in the arm member 10, the base of the arm member 10 tends to move to the left together with the connecting member 32. Since the support shaft 12 formed in the arm member 10 is fitted into the engagement hole (7) formed in the shoulder member 2, the arm member 10 is To rotate.
Similarly, when the operating shaft 15 moves to the right, the arm member 10 rotates to the left around the support shaft 12. The other arm member 10 operates in the same manner as the arm member 10 described above. Therefore, as a whole, the arm member swings left and right.

Since both ends of the operating shaft 15 pass through the center of the connecting portion between the body portion 1 and the shoulder member 2, the shoulder member 2 rotatably connected to the body portion 1 by the connecting portion 5 is connected to the body. The relationship between the arm member 10, the connecting member 20, and the operating shaft 15 with respect to the shoulder member 2 is constant even when the member 1 is rotated with respect to the part 1. Therefore, when the operating shaft 15 is operated regardless of the angles at which the left and right shoulder members 2 are rotated, the arm member 10 can be swung at the position where the shoulder member 2 is rotated.

The waist and the torso of the robot toy are detachably formed on the lower body, and the separated torso and the waist are attached to a running toy (not shown) to drive the toy and the like. By connecting the robot to the operation shaft of the robot toy, it is possible to extend the range of play, for example, by operating the traveling toy with a remote controller or the like to cause the robot to fight the robot toy of the other party.

The present invention is not limited to a robot toy. It can also be applied to doll toys and animal toys.

[0021]

As described above, by rotating the operation shaft to operate the drive mechanism, the body rotates relative to the waist.
The operating shaft reciprocates left and right in conjunction with the rotation of the body
The arm swings with respect to the shoulder,
You can swing your arms while turning
It is not a structure in which only the arm moves while stopped, so
The rough swinging of the arm can be achieved. Therefore, for example, a robot toy that is ideal for playing where robot toys confront each other and fight like a boxing is realized
Can be moved away from the toy that simply swings the arm
In addition, it is possible to expand the range of play such as development to a game.
