Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic transformation robot toy that automatically changes its shape from a running toy to a robot toy, and more particularly to a technique of an automatic transformation mechanism that automatically changes its shape.

(Prior Art) As a toy that infants are interested in, there is a robot toy.
Recently, among the robot toys, there is a tendency to show an interest in so-called transformation robot toys, in which the arms and legs can be bent, and the bent to have other forms. Many of these transforming robot toys are adapted to be robot toys in the state of being transformed from a traveling toy such as an automobile.

(Problems to be Solved by the Invention) However, in such a transforming robot toy, a moving toy such as an automobile can be transformed into a robot toy by individually changing the shape of each part (eg, arm or leg). Therefore, the transformation form is complicated and the degree of the form change is small, and the work of changing the form is complicated and troublesome for infants and the like. Further, since the shape change itself is performed manually by an infant or the like, there is a problem that the robot-likeness as a transformation robot (that is, the robot-like transformation automatically) cannot be realistically expressed. . Further, if the order of the above-mentioned change in form of the toy is clarified, the interest in the toy is inevitably diminished, and the toy itself becomes tired.

Therefore, the object of the present invention is to make it possible to perform a strange automatic transformation with a large degree of morphological change with a simple mechanism and to realistically express the robot-likeness as a robot toy. It is to provide an extremely interesting automatic transformation robot toy that is rich in nature.

In addition, the second power transmission unit (10) is used when the tank drive toy (1) and the first drive system (10a) that meshes with the automatic transformation mechanism (6) described later are automatically transformed into a robot toy. It is composed of a second drive system (10b) for traveling. The first drive system (10a) is fixed to the two shafts (12), (12) and the shafts (12), (12) that are rotatably mounted on the box (2a), and the motor is Large diameter gear that meshes with gear (7a) of (7)

It has a fitted spring (23).

This fan-shaped gear (60) is provided with the spring (23) when the biaxial motor (7) is operating in the normal direction described later.
Due to the urging force in the contraction direction, it is configured so as not to mesh with the pinion gear (12f) of the large diameter gear (12d).

On the other hand, in the turret (4) described above, it is not possible to control the rotation direction of the biaxial motor (7) in the forward rotation direction (see arrow F in FIG. 3) and the reverse rotation direction (see arrow E in FIG. 3). The illustrated drive unit is housed inside. This driver is an integrated circuit I

The second power transmission unit (10) does not participate in the traveling of the tank traveling toy (1) itself, and therefore the traveling as the tank traveling toy (1) is performed by the caster vehicle via the first power transmission unit (9). (11)
Will only perform mystery travel.

Next, in the mystery traveling state, by the control of the drive unit (not shown) described above, after a predetermined time has elapsed, the both-shaft motor (7) is reversed based on the signal of the drive circuit, and the power transmission system (8) The first power transmission section (9) and the second power transmission section (10) are rotated as shown by an arrow A in FIG. By this rotation action, the second power transmission unit (10) and the first drive system
