[Industrial applications]

 The present invention relates to a remote-controlled toy.

[0002]

[Prior art]

 Conventionally, an electric motor that can rotate in the forward and reverse directions has been used as a remote-controlled toy, and when the electric motor rotates in the forward direction, a pair of left and right drive wheels are rotated in the forward direction to move the toy body forward. It is known that one of the pair of left and right drive wheels is rotated in the forward direction and the other drive wheel is rotated in the reverse direction to rotate the toy body during reverse rotation.

According to this remote-controlled toy, one electric motor can cause the toy body to perform two types of operations, so that an inexpensive and enjoyable remote-controlled toy can be realized.

[0004]

[Problems to be solved by the device]

 However, in this type of remote-controlled toy, two movements and morphological changes that are inevitably associated with these movements occur due to the forward and reverse rotations of the electric motor, but the morphological changes independent of the moving parts do not occur mechanically. Since it was not revealed, it was not possible to express the desired morphological change sufficiently.

The present invention has been made in view of the above points, and an object thereof is to provide a remote-controlled toy capable of sufficiently expressing a desired shape change as well as a plurality of operations.

[0006]

[Means for Solving the Problems]

 A first means is a remote-controlled toy in which the electric motor is normally and reversely rotated by remote control so that the toy body can continuously perform a plurality of operations. A sun gear that rotates is provided, and two planet gears that revolve around the sun gear while revolving around the sun gear are provided. Two planetary gears are provided so as to overlap each other with two toothless gears that can be selectively meshed, and one of the two toothless gears is connected to one of the toothless gears in accordance with the forward / reverse rotation of the electric motor. The shape of the toy body can be changed by rotating the toothless portion to a position where it does not mesh with the corresponding planetary gear.

A second means is the toy body according to the first means, wherein the toy body is provided with a base to which a pair of left and right drive wheels are attached, and a standing posture and a forward leaning posture on the base. When the electric motor rotates in the forward direction, the pair of left and right drive wheels rotate in the forward direction, and when the electric motor rotates in the reverse direction, one of the left and right drive wheels in the forward direction and the other in the forward direction. It is designed to rotate in the reverse direction, and the doll should take a forward leaning posture when the electric motor rotates forward and a standing posture when the electric motor rotates backward by the operation of the two toothless gears. It is characterized in that it is configured to change the form.

In the first or second means, a link mechanism may be connected to the toothless gear, and the form may be changed by the link mechanism.

[0009]

[Action]

 According to the above-mentioned means, it is possible to perform a plurality of actions and also to change the morphology independent of the action, so that the main body of the toy makes a desired morphological change mechanically independent of the action. You can also

For example, if configured as the second means, when the toy body moves forward, the doll can be tilted forward to express the flying state of the doll, and at the same time when the toy body turns, the doll moves. You can stand up and express how the doll's orientation changes. Further, if the link mechanism is connected to the toothless gear, the degree of freedom in changing the form of the toy body is increased and, if necessary, the motion associated with the change in form can be amplified.

By doing so, the monster 8 is also following. Both arms 8a, 8a of this monster 8 are connected by a shaft 8b so as to be interlocked by the action of gravity. In addition, in FIGS. 7 and 8, reference numeral 44 indicates a shaft pressing plate.

A torsion spring 43 is wound around the shaft 41. One end of the torsion spring 43 is hooked on the inner fixing portion of the monster 8, and the other end is hooked on the inner fixing portion of the shaft pressing plate 44. The monster 8 is urged by the spring 43 in the standing direction.

In FIG. 8, reference numeral 45 is a surface clutch. When the button operation of the controller 2 is performed while the monster 8 is being held by hand, the surface clutch 45 allows the link 31c to move in the direction in which the push spring 46 contracts against the urging force of the push spring 46, and the toy main body is released. It works to prevent damage to the mechanism inside 3. Further, in FIG. 7, reference numeral 50 indicates a lid of the battery storage chamber, and in FIGS. 2 and 7, reference numeral 90 indicates a caster.
