Description

[Detailed description of the invention] (Field of industrial application) The present invention is a flywheel that achieves the compactness of a traveling toy by utilizing the hollow part in the tire wheel for traveling as a flywheel storage part. Regarding the running toy used.

(Prior art and its problems) There are various types of running toys using conventional flywheels, such as toy cars and toy motorcycles. These are configured so that a flywheel is mounted as a drive source on the chassis of the vehicle body, and the rotational force of the flywheel is transmitted to the tire wheels via transmission means such as gears to make the vehicle travel. . In addition, a shape-changing toy that uses a flywheel has also been proposed so that a single toy can freely change its shape between two shapes: a traveling toy and a robot.

However, in the case of conventional traveling toys using a flywheel, the flywheel was mounted on the vehicle body itself and was separate from the tire wheels, so there was a problem that the vehicle body became large. Especially when it comes to shape-changing toys such as those mentioned above,
Since various attached parts such as the robot's arms, legs, face, etc. are stored in the body part, the flywheel drive part, which becomes an extra component when transformed into a robot, should be exposed to the outside as much as possible. It is preferable not to have it.

(Technical problem of the invention) The present invention was made in view of the above, and in order to prevent the flywheel from increasing in size due to being mounted on the car body, it is necessary to install the flywheel inside the tire wheel supported by the car body. The technical challenge is to provide a running toy that houses a flywheel.

(Means for Solving the Problems) In order to solve the above problems, a traveling toy using a flywheel according to the present invention is characterized by comprising the following constituent requirements.

(a) A ridge is formed on one side from the outer peripheral surface of the tire wheel in which the flywheel is housed, and a recess is formed by the ridge and the side wall of the tire wheel.

(b) One of the rotating shafts of the flywheel protrudes outward through the center of the side wall of the tire wheel, and a pinion gear is fixed to the tip.

(c) A coaxial gear is fixed coaxially with the rotating shaft to the outside of the side wall of the tire wheel, and a transmission gear that meshes with the coaxial gear and the pinion gear is rotatably provided on the vehicle body.

(d) The pinion gear, coaxial gear, and transmission gear are arranged within the recess.

(Operation of the invention) According to the above configuration, when the tire wheel rotates, the coaxial gear also rotates, so the rotational force is transmitted to the pinion gear via the transmission gear of the vehicle body, and further, as the pinion gear rotates, the flywheel is rotated. Rotate.

(Example) Hereinafter, a traveling toy using the flywheel of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the entire traveling toy of the present invention, and this traveling toy has a vehicle body 1 that transforms into a robot, and tire wheels 10 rotatably supported by the vehicle body.

FIGS. 2a and 2b are explanatory diagrams of the configuration of the main parts of the present invention, and the tire wheel 10 is made up of two frame members 11 and 12 rotatably supported by the support parts 1a and 1b of the vehicle body 1. The flywheel 20 is generally composed of a hollow frame 13 and a flywheel 20 housed coaxially and relatively rotatably within the frame 13.

A rotating shaft 21 is integrally formed at the center of the flywheel 20. A projecting edge 11 a is formed on one side from the outer peripheral surface of the first frame member 11 , and a recess 23 is formed by the projecting edge 11 a and the side wall 14 . One of the rotating shafts 21 passes through the center of the side wall 14 and protrudes outward, and a pinion gear 1 is attached to the tip.
7 is fixed. Furthermore, a coaxial gear 15 is fixed on the outer side of the side wall 14 coaxially with the rotating shaft 21 . Further, a transmission gear 4 having an integral structure of a large gear 2 and a small gear 3 is rotatably supported on the support portion 1a of the vehicle body, and the large gear 2 is connected to a pinion gear 17.
The small gear 3 is meshed with the coaxial gear 15, respectively. The pinion gear 17, coaxial gear 15, and transmission gear 4 are arranged within the recess 23. Therefore, the rotational torque of the frame member 11 is transmitted to the flywheel 20 via the coaxial gear 15, the transmission gear 4, the pinion gear 17, and the rotating shaft 21. The second frame member 12 is fitted onto the first frame member 11, and has a rotating shaft 12 protruding from the center on the outer surface (left side in FIG. 2a).
A is rotatably supported by the support portion 1b.

In the above configuration, in order to rotate the frame 13, when the outer peripheral surface of the frame 13 (usually a rubber tire not shown) is frictionally rotated on the floor surface,
The rotational torque is sequentially transmitted to the flywheel 20 via the coaxial gear 15, the transmission gear 4, the pinion gear, and the rotating shaft 21, causing the flywheel 20 to rotate. The inertia generated by the rotation of the flywheel 20 allows the flywheel to continue rotating even after the frame 13 stops rotating. Due to the large rotational energy held in the flywheel 20, the frame 13 is rotated in the opposite direction, and the vehicle body 1
It can be run with

3a and 3b show another embodiment of the present invention,
The coaxial gear 15 is connected to the side wall 1 of the first frame member 11.
A brake member 18 is rotatably supported in the center hole of 4 by a rotating shaft 15a, and is integrated with the coaxial gear 15 on the inner surface of the side wall 14 by a common rotating shaft 15a. By engaging with the tips of arms 18a and 18b,
This embodiment is different from the above-described embodiment in that a plurality of stoppers 19 are provided to limit the rotation direction of the brake member 18 and the coaxial gear 15 only to the forward direction indicated by the arrow. That is, the brake member 18 has two resin arms 18a and 18b that curve and extend in the radial direction around the rotating shaft 15a, and the tips of the arms include a locked portion 18c that projects in the outer radial direction.
18d, and when the brake member and the coaxial gear 15 are about to rotate in the forward direction, the locked parts 18c and 18d elastically deform in the inner diameter direction and overcome the stopper 19, thereby rotating in the same direction. While the rotation is allowed, if you want to rotate in the opposite direction, place a stopper on the end face of the locked part.
9 engages to prevent this.

In the above configuration, when the frame is stopped or decelerated while the flywheel 20 and frame 13 are rotating at high speed in the forward direction,
Although the transmission gear 4 and the coaxial gear 15 try to stop or decelerate, they are still forced to rotate by the large drive torque from the flywheel, which continues to rotate at high speed in the same direction.
Although there is a risk that excessive force will be applied to the transmission gear 4 and the coaxial gear 15, causing damage, such problems can be solved by using the brake member 18. That is, when only the flywheel 20 attempts to continue rotating in the forward direction as a result of the frame being stopped and decelerated, the rotational torque of the flywheel is transmitted to the pinion gear 17, the transmission gear 4, and the coaxial gear 1.
5 and the coaxial gear tries to rotate in the forward direction, but the stopper 19 stops the brake member 1.
8 and the coaxial gear 15 can be allowed to rotate in the forward direction, in other words, the locked portion 18c of the arm of the brake member 18, which rotates integrally with the coaxial gear,
Stopper 1 with 18d arranged at predetermined intervals
Since the brake member and the coaxial gear are allowed to rotate relative to the frame 13 while successively overcoming the points 9, even if an unreasonable force is applied to the coaxial gear, this can be eliminated. At the same time, the rotational force of the flywheel due to inertia is gradually reduced.

Figure 4 a, b and Figure 5 a, b show the configuration before and after the shape change of the shape-changing traveling toy (shown in Figure 1) using the tire wheel housing the flywheel. The explanatory diagram, FIG. 6, is a side view after the shape has changed, and this toy has a trunk 30.
, tire support parts 1a and 1b rotatably supported by the body part 30, a tire wheel 10, and a face rotatably supported by the connecting rotation shaft between the tire support part 1a and the body part 30. 35, an arm member 40 rotatably supported by a connecting member 41 rotatably supported in the front-rear direction by an arm support portion 31 formed on an upper side surface of the trunk 30; A pair of leg members 50 rotatably supported below the section 30;
It is generally comprised of a tip member 33 located between a pair of leg members 50, rotatably supported in the front-rear direction by the trunk 30, and holding a front wheel 32 on its lower surface. Each member other than the tire wheel 10 constitutes the vehicle body 1. A transparent windshield 34 is supported at its lower end on the front surface of the body section 30 so as to be openable and closable, and its back surface forms a recess 30a for storing the arm member 40. That is, since the arm member 40 is configured to be rotatable in the front-rear direction by the connecting member, it is housed and held in the recess 30a on the back surface of the trunk. The recess 30a is also useful for storing the supports 1a, 1b and the tire wheels 10 which are thrown backwards when the robot is turned into a robot. Before the face part 35 changes form, it is stored in the face part storage recess 30b above the torso, but when the form changes to a robot, the face part 35 is stored in the face part storage recess 30b.
etc., when it is thrown backwards, it rotates backwards and stands up independently of the support part. The leg portion 50 is configured to be rotatable at the knee 51 and the lower end portion 52, and the lower end portion 52 rotates from the dotted line position to the solid line position. When it is a robot, it is rotated to the solid line position and transformed into a boot-like shape, and when it is a traveling toy, it is moved to the dotted line position.

(Effects of the invention) As explained in detail above, according to the invention,
Since parts such as the flywheel, pinion gear, coaxial gear, and transmission gear are all disposed within the tire wheel and recess, these parts prevent the vehicle body from becoming larger. The pinion gear, coaxial gear, and transmission gear are arranged within the recess,
Since it is not exposed to the outside, the appearance is not impaired. Furthermore, these gears are exposed within the recess by removing the tire wheel. Therefore, gears can be easily replaced in the event of a failure.
