Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rotating mechanism for a rotating body in a toy that can be rotated by a predetermined rotation angle in different directions depending on the rotational direction of a motor.

(Prior art and its problems) Conventionally, this type of toy has been used only for the purpose of running, and has other functions added to the main function of running, such as moving parts of the car body or mounted parts, or changing the shape. The additional functions that were offered were not given much importance. For this reason, it has been proposed that a rotating body is provided in a part of the vehicle body, the rotating body is rotated back and forth by a predetermined angle, and a vehicle is played by attaching appropriate members to the rotating body. However, in the above-mentioned rotation mechanism, there have been cases where the rotation of the rotating body stops and the next reversal is not successful.

(Problem to be solved by the invention) The present invention has been made in view of the above-mentioned points of view, and is a particularly simple structure that reliably rotates a rotating body provided on the vehicle body back and forth by a certain angle. The purpose of this study is to propose a rotating mechanism for a rotating body in a toy that can be used as a toy.

(Technical means to solve the problem) As a technical means to solve the above problem,
The rotation mechanism of the rotating body in the toy according to the present invention is as follows:
A toy equipped with a motor capable of forward and reverse rotation and a rotating body rotatably supported at a predetermined position, characterized by meeting the following requirements.

(a) A rotation receiving member that makes surface contact with a rotating member rotationally driven by the motor is formed on a part of the periphery of the rotating body.

(b) The rotating body is configured to allow rotation of the rotating body within a certain range and prevent further rotation in the same direction so that the rotating member and the rotation receiving member are in a non-contact state. An elastic member must be in contact to prevent this from happening.

(Operations and Effects of the Invention) As described above, in the rotating mechanism of the rotating body in the toy according to the present invention, the rotating member rotates regardless of whether the motor is rotated in the forward or reverse direction. The rotating body receiving member in surface contact is driven by the contact resistance, and the rotating body rotates.
In this case, since the rotation receiving member is provided only on a part of the periphery of the rotating body, the rotating body will stop if it comes out of contact with the rotating member, but in order to prevent this situation, the rotating body is made of elastic material. Since the contact state with the rotation receiving member is maintained by the member, when the motor reverses, the rotating member also reverses and the rotating body is in surface contact, so the contact resistance causes the rotation in the opposite direction. Rotate to. This rotation is also prevented by the elastic member from coming into contact with the rotation receiving portion and the rotating body, as described above. Therefore, the rotating body reliably rotates by a predetermined angle within the range of surface contact between the rotation receiving member and the rotating member.

(Example) Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

In the figure, symbol A indicates a rotating mechanism of a rotating body in a toy according to the present invention. The rotating mechanism A of this rotating body is composed of a motor 1, a rotating member 2, a rotating body 3, and an elastic member 4.

The motor 1 is installed on a machine stand 6, and a pinion 7 is fixed to its output shaft 1a.A spur gear 9 is connected to one end of the pinion 7 via a shaft 8, and a pinion 10 is connected to the other end of the motor 1. The spur gears 9 of the rotating member 2 are meshed with each other. The rotating body 3 is rotatably supported by a support shaft 11 erected on the base 6, and an arc-shaped rack 12 is integrally protruded from the periphery of the lower surface of the rotating body 3. An arcuate guide groove 13 is formed at the position. The rack 12 is meshed with the pinion 10 of the rotating member 2, while the tip of the elastic member 4, which is a plate spring whose base end is fixed to the base 6, is loosely fitted into the guide groove 13. .

Since the rotation mechanism A of the rotating body in the toy is configured as described above, when using it,
First, by rotating the motor 1 in either forward or reverse directions, the rotating body 3 can be rotated back and forth via the rotating member 2. In this case, as the rotating body 3 rotates, the pinion 10 of the rotating member 3 and the arc-shaped rack 12 provided on the lower surface of the rotating body 3 are prevented from becoming out of mesh, as shown in FIGS. 2a to 2c. Therefore, within a certain rotation range, the rotating body 3 is biased in the opposite direction to the rotation by an elastic member 4 made of a leaf spring loosely fitted in the guide groove 13. Therefore, when the motor 1 reverses, the rotating member 2 also reverses, and the meshing state between the rack 12 provided on the rotating body 3 and the pinion 10 is always maintained, so that the rotating body 3 is also reliably rotated in the opposite direction. Rotate. After rotation, the rack 12 and the pinion 10 of the rotating member 2 are held together by the elastic member 4 in the same manner as above.
and are prevented from becoming disengaged. Therefore, the rotating body 3 has a rack 12 provided on its lower surface.
The rotary member 2 and the pinion 10 rotate reciprocally in the forward and reverse directions within the range of the meshing state between the rotating member 2 and the pinion 10.

Next, FIGS. 3a and 3b show a toy in which the rotating mechanism A of the rotating body is used to open and close the doors 20, 20 of a traveling toy B. The support shafts 15, 15 provided thereon and the support shafts 21, 21 provided on the upper surfaces of the doors 20, 20 near the open ends are linked via connecting members 22, 22. As a result, the rotating body 3
By rotating the motor 1 in either forward or reverse directions, the doors 20, 20 can be easily opened and closed.

In addition, although the above-mentioned system utilizes the rotation mechanism of the rotary body to open and close the door of a traveling toy, it is not limited to this, and for example, it may be formed so that a doll is placed on it and the doll moves from side to side. .

Further, in the above example, a pinion and a rack are respectively applied as the rotation receiving members that make surface contact with the rotating member 2 and the rotating body 3, but the invention is not limited to this.
The roller of the rotating member and the planar lower surface of the rotating body may be in surface contact with each other.
