Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] The present invention relates to a traveling toy that runs using a small toy engine as a power source.

[Conventional technology and problems to be solved] Traditionally, traveling toys that run using a toy engine as a power source are widely popular not only among children but also among adults because they run with a sense of speed. .

However, in conventional traveling toys of this type.

Generally, since a glow engine is used, a buff battery, ignition plug, ignition cord, etc. are required for starting, which makes the structure complicated and requires time and effort to operate and adjust.

This has made it difficult for children and the like to handle it easily.

Solution to Problem c] The present invention, which solves the above conventional problems, provides a running toy that runs using a small toy engine as a power source, uses a diesel engine as the small toy engine, and connects the diesel engine and the axle. a fuel supply section that connects the axles to drive the axle to rotate and supply fuel to the diesel engine, and a starter section that starts the diesel engine by applying rotation to the output shaft of the diesel engine. .

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

1 to 9 show a running toy according to an embodiment of the present invention, the running toy includes a diesel engine 1 for a small toy, a flywheel 2, a starting device 20.
A direction changing device 30, a gear group 3, etc. are mounted on a chassis 4, and a body 5 imitating the shape of a car is placed thereon.

The above diesel engine l sucks in a mixture of air and fuel containing kerosene, ether, lubricating oil, etc., burns it to generate power, and rotates the output shaft la. In the example, the diesel engine l
Since the engine is used as a power source, the ignition plug, ignition cord, battery, and other parts required for the ignition engine are not required, simplifying the structure and making starting operations easier.

FIG. 4 shows the structure of the diesel engine 1. Here, the diesel engine 1 includes an output shaft 1a, a cylinder body 1b, a piston ld connected to a crank lc,
It consists of a cylinder head 1e attached to the upper part of the cylinder body 1b. The combustion chamber If provided inside the cylinder head le has a conical cross section as shown in the figure, thereby improving the ignition efficiency.

The flywheel 2 is connected to the output shaft 1a,
Rotationally driven by the power of a diesel engine. This flywheel 2 exerts a gyroscopic effect by rotating and maintains a stable posture during wheelie running, single-wheel running, etc. In order to maximize the effect, the sizes of the chassis 4 and body 5 are , its dimensions, weight, etc. shall be determined taking into consideration the overall weight.

This flywheel 2 has four long holes 2a.

2a are provided radially. These elongated holes 2a are opened by tilting 1w so that the upper surface side runs with respect to the rotational direction of the flywheel 2 (in the direction of the arrow in the figure). That is, as the flywheel 2 rotates, the air on the upper surface side flows downward along the wall W of the elongated hole 2a and is blown in the direction of the diesel engine l, so that the cooling effect of the diesel engine 1 can be obtained. It has become.

The gear group 3 includes a gear 6 provided on the output shaft 1a, three intermediate gears 7, 8 and 9, and a crown gear 11 supported on the rear axle IO. These gears sequentially mesh to transmit the rotation of the output shaft 1a at a reduced speed, thereby rotationally driving the rear axle 1O. As shown in the figure, a crown gear 11 and a sprocket 12 are fitted to the rear vehicle #IIO. These each include a clutch portion 11a, 12a, and a spring 13.
are pressed together and interlocked. For this reason, power from the diesel engine 1 is normally transmitted to the rear axle 10, but if a load above a certain level is applied to the rear axle 11, the clutch parts 11a and 12a will slip, causing the crown gear 11 to spin idle and the diesel engine l and gear group 3
without damaging it.

The sprocket 12 is connected to the sprocket 16 of the front axle 15 by a chain bell 14, and when the rear axle 10 is driven, the front axle 15 is also driven at the same time. That is, the running toy is configured to drive the front wheels 17 and the rear wheels 18 to rotate simultaneously, thereby running in four-wheel drive.

The starting device 20 is configured to transmit the rotation of the rotating device 21 to the flywheel 2 and the output shaft 1a of the diesel engine 1 via a starting gear 22 made up of a gear 6 and an intermediate gear 7.

The rotating device 21 applies the rotation required for starting the diesel engine to the output shaft 1a, and as shown in FIG.
5, consisting of transmission IIIk26.

The handle 24 is attached to a rotary shaft 24a rotatably provided in the case body 23. The transmission gear portion 25 includes a gear 25a provided on a portion of the rotating shaft 24a located inside the case body 23, a gear 25b meshing with the gear 25a, and a bevel gear 2 provided coaxially with the gear 25b.
5c, and a bevel gear 25d provided at one end of the transmission shaft 26 that meshes with the bevel gear 25c. Further, the transmission shaft 26 is rotatably attached to the lower part of the case body 23. With this structure, when the handle 24 is held and rotated, the rotation is transmitted to the transmission gear portion 25.
is accelerated and transmitted to the transmission shaft 26.

Next, the starting gear 22 includes a gear 6 and an intermediate gear 7 that transmit the rotation of the output shaft 1a of the diesel engine 1 to the rear axle 10.
The transmission shaft 26 of the rotating device 21 is fitted onto the axis of the intermediate gear 7, and the rotation member 2 is configured using the
7 are integrally attached. Here, the tip of the transmission shaft 26 is formed to have a polygonal cross section, and the fitting member 2
7 is formed with a polygonal fitting hole 27a that matches the shape of the tip of the transmission shaft 26. Further, the fitting member 27 is positioned so as to protrude from the upper surface of the body 5.

That is, the tip of the transmission shaft 26 of the rotating device 21 is fitted into the fitting hole 27a of the fitting member 27 as shown in FIG.
4 in a predetermined direction, the rotation of the transmission shaft 26 is transmitted to the output shaft 1 of the diesel engine 1 via the intermediate gear 7 and the gear 6.
a, and the diesel engine 1 is started. Generally speaking, a diesel engine 1 has a higher compression ratio than a glow engine, so it requires a large force to start by rotating the output shaft 1a, making it difficult to start.In this embodiment, a flywheel 2 is attached to the output shaft 1a. Since these are connected, when rotation is applied by the rotating device 21, the inertial force of the flywheel 2 acts, making it easier to start the diesel engine l. That is, when the handle 24 of the rotating device 21 is turned by a certain amount by applying a certain force, rotational force is applied to the output shaft 1a by the inertial force of the flywheel 2, so there is no need to apply any more force to the handle 24, which is simple. It can be started with a small amount of force.

The direction changing device 30 includes a gear portion 31, a cam 32, and a vertically movable pin 33. The gear portion 31 includes a gear 31a fixed to the front axle 15, intermediate gears 31b, 31b, and a cam 32, which transmit the rotation of the gear 31a to the cam 32.
It incorporates a plurality of gears including a gear 31c provided coaxially with the intermediate gears 31b, 31b and the gear 3.
1c are each supported by a frame member 34 provided on the chassis 4L. The cam 32 is a disk cam and is integrally provided on the rotation shaft of the gear 31c. This cam 32 is
As shown in the figure, it is provided so as to be located outside the frame member 34.

The vertically movable bin 33 is attached to a holding section 3 provided on the chassis 4.
The lower end portion 33a extends downwardly through the lower surface of the chassis 4. Also,
The upper end portion 33b is located opposite the cam 32 from below. A spring spring 36 is installed between the holding member 35 and the north end 33b of the vertically movable bottle 33.
The vertically movable bin 33 is constantly pushed upward by the spring spring 36, and its upper end 33b is in pressure contact with the cam 32.

With the structure of the direction changing device 30 as described above, when the front axle 15 is rotated by the chain bell 14 when the traveling toy is running, the rotation is decelerated by the gear part 31 and transmitted to the cam 32, and the cam 32 rotates eccentrically. . The eccentric rotation of the cam 32 pushes the vertically movable pin 33 downward at regular intervals. When this vertical movement pin 33 is pushed down, one (left side) of the front wheel 17 is lifted from the running surface, and the vertical movement pin 33 is used as a fulcrum.
By performing turns, spins, etc., and by combining the direction change by the vertical movement pin 33 and the gyroscopic effect by the flywheel 2, a very unique and interesting running state can be obtained.

A guide 37 having a tapered surface 37a is provided on the lower surface of the chassis 4 in front of the vertical movement pin 33 as shown in the figure.If an obstacle is encountered while the traveling toy is running, the guide 37 will remove the obstacle. Vertical movement pin 33 that climbs over objects
is designed so that it does not get caught directly on obstacles.

The body 5 is placed on the chassis 4 with the diesel engine 1, flywheel 2, gear group 3, and direction changing device 30 covered thereon. The body 5 is formed in a shape imitating the shape of a car, and support members 40, 40 resembling door mirrors are provided on both sides of the body 5 to protrude laterally. This support member 40.40 is used to prevent the toy from falling over due to its tip hitting the running surface when the toy runs on one wheel, and to ensure stable one-wheel running due to the gyroscopic effect. It is something. Further, auxiliary wheels 41 and 41 are rotatably provided on both sides of the rear portion of the body 5. These auxiliary wheels 41.41 are for keeping the running condition stable when the running toy runs a wheelie.When the running toy runs a wheelie due to the gyroscopic effect, the auxiliary wheels 41.41 touch the ground on the running surface. Support that attitude.

Note that a fuel tank 42 for storing fuel inside is attached to the side surface of the body 5 of the traveling toy. Further, the fuel tank 42 is connected to the diesel engine 1 through a pipe.
It is now possible to send fuel to.

Next, the operation of the above traveling toy will be explained.

First, the chassis 4 of the running toy is placed on a stand at a predetermined height, with the front wheels 17 and rear wheels 18 lifted above the running surface, and the rotating equipment fi! The transmission shaft 26 of 121 is fitted into the fitting hole 27a of the fitting member 27. In this state, rotating equipment @21
When you turn the handle 24.

The output shaft 1a of the diesel engine 1 and the flywheel 2 start rotating via the intermediate gear 7 and the gear 6.

Due to the rotation of the output shaft 1a, the diesel engine l
The engine starts by exploding and burning the fuel sucked from the fuel tank 40, and rotates the output shaft 1a and the flywheel 2 at high speed. In addition, the rotational driving force of the output shaft 1a is the gear group 3
As described above, the rear wheels 18 and the front wheels 1 are
7 and drives both wheels.

If the running toy is taken down from the stand and placed on a running surface such as the floor in this state, the running toy will run on four wheels at an appropriate speed while rotating the flywheel 2 at high speed.

When the flywheel 2 rotates at a high speed, the gyroscopic effect flAs tries to keep the running state of the running toy constant, and the running toy runs in a stable state without being blown off by unevenness on the road surface. For example, if you run on one wheel, the gyroscopic effect will maintain that running state, and
If the front wheel 17 is raised and wheelie is performed, the vehicle can run stably while maintaining the wheelie state.

In addition, as described above, the vertical movement pin 3 of the direction changing device W130
3 performs direction changes such as U-turns and spins by moving up and down, and this, combined with the gyroscopic effect described above, provides an unexpectedly extremely varied running state.

Furthermore, in conventional running toys powered by an engine, if the vehicle body is tilted and fuel is temporarily cut off from the fuel tank, the engine may stop. In the toy, the flywheel 2 is connected to the output shaft la of the diesel engine 1 as described above, so even if the fuel supply is temporarily stopped and the diesel engine 1 stops, the inertial force of the flywheel 2 is maintained. The output shaft 1a continues to rotate for a certain period of time.

Therefore, if the attitude of the vehicle body returns to its original state while the vehicle is rotating and fuel is supplied, the diesel engine 1 will start again and continue traveling.

In the embodiment, the rotation is transmitted to the front axle 15 by the chain belt 14 and the vehicle runs in four-wheel drive, but it is also possible to drive only the rear axle 10 and drive in two-wheel drive.

[Effects of the Invention] As described above, the present invention uses a diesel engine as a power source and rotates the axle, thereby eliminating the need for batteries and plugs to start the engine, which simplifies the structure. In addition to this, it also becomes easier to handle during starting operations, etc., so that it can be easily operated even by children.
