In the figure, a gasoline engine car 1 has a gasoline engine 2 for a small toy, a flywheel 3, an ignition device 10, a gear group 20, etc. mounted on a chassis 5 as a toy body, and a body 6 imitating the shape of a car is mounted on the chassis 5. It will be covered.

The gasoline engine 2 for small toys (hereinafter simply referred to as engine) is similar to a general gasoline engine,
It sucks in a mixture of gasoline fuel and air, burns it to generate power, and rotationally drives the output shaft 2a.

As shown in FIGS. 1 to 3, the ignition device 10 includes a nichrome wire 11 as a heating element installed in the engine 2, a socket 13 as a plug-in type connecting device, and a plug-in type connecting device. It consists of a plug 14 and the like.

The nichrome wire 11 is a member that generates heat when current flows through it, and is installed at the head of the engine 2. Further, the nichrome wire 11 is connected to the connecting member 1
2 and 12 are electrically connected to the socket 13. One end side of the connecting members 12, 12 forms U-shaped clamping parts 12a, 12a, and these clamping parts 12a, 12a also hold the nichrome wire 1.
The engine 2 maintains electrical connection with a protrusion 11a that is electrically connected to the engine 1 and protrudes from the head of the engine 2.

The socket 13 forms an opening 13b,
It is provided with a protrusion 13a that is convex from the inside toward the opening surface. The socket 13 is provided on the chassis 5. On the other hand, the plug 14
A recess 14a is formed to fit into the projection 13a, and electrical connection is obtained by press-fitting the recess 14a into the projection 13a. Also, the plug 14 is connected to the socket 1.
The diameter of the plug 14 is smaller than that of the socket 13, and the plug 14 itself is fitted into the socket 13.

On the other hand, the plug 14 is electrically connected to a battery 16 as a power source via cords 15, 15, and the battery 16 is connected to a nichrome wire inside the engine 2 via the plug 14, the socket 13, and the connecting members 12, 12. A current is supplied to 11.

That is, by connecting the plug 14 and the socket 13, current from the battery 16 is supplied to the nichrome wire 11, the nichrome wire 11 generates heat, and the engine 2 can be started. Therefore, simply connecting the plug 14 and the socket 13 makes it possible to ignite the cylinder of the engine 2, making it easy to start the engine.

The flywheel 3 is attached to the output shaft 2a and is rotationally driven by the power of the engine 2.
The flywheel 3 exerts a gyroscope effect by being rotationally driven and maintains the vehicle body in a stable state. This flywheel 3 is provided with long holes 3a for blowing air, and the engine 2
It also serves as a cooling device.

On the other hand, the gear group 20 includes a gear 21 provided on the output shaft 2a, an intermediate gear 22 supported on the shaft 22a, intermediate gears 23 and 24 supported on the shaft 23a, and a rear axle 25 as shown in FIG. 1st supported
It is composed of a crown gear 26. These gears sequentially mesh to transmit power, and the power of the output shaft 2a is decelerated to rotationally drive the rear axle 25.

As shown in FIGS. 4 and 5, a first crown gear 26 is loosely fitted onto the rear axle 25, and a second crown gear 27 is fixedly secured thereto.
Each of these has a clutch portion 26a, 27a, which are pressed against each other by a spring 28 and mesh with each other. Normally, the power from the engine 2 is transferred to the rear axle 26a, 27a.
5. When a load is applied to the rear axle 25 side, the clutch parts 26a and 27a slip, so the first crown gear 26 idles and the engine 2 and gear group 20 are not damaged.

Further, the second crown gear 27 is connected to a third crown gear 32 of the front axle 31 by a shaft 30, and when driving the rear axle 25,
The front axle 31 is also driven at the same time. That is, the gasoline engine car 1 rotates the front wheels 52 and the rear wheels 53 to run in four-wheel drive.

Next, the starting device for the engine 2 will be explained based on FIG. 2. A gear 40 is meshed with the gear 21 provided on the output shaft 2a, which is connected to the frame 41.
It is supported in the elongated hole 41a. In addition, the frame 41 has
Three auxiliary rollers 42 are supported at a certain distance from this gear 40. These are the long holes 41a
Three pieces are provided on a straight line parallel to the longitudinal axis of the
It assists the meshing of a starter 43, which will be described later, with the gear 40.

As shown in FIG. 2, the starter 43 has hook-shaped teeth 43a formed on one side of its rod-like body, and a handle portion 43b attached to one end. When starting the engine 2, the output shaft 2a can be rotationally driven by inserting the starter 43 between the gear 40 and the auxiliary roller 42 and pulling the starter 23 in the direction of the arrow in the figure with the gear 40 and teeth 43a meshed. Note that when the starter 43 is inserted between the gear 40 and the auxiliary roller 42, the gear 40 is inserted into the second position along the elongated hole 41a.
Since it moves toward the front in the figure, the teeth 43b and the gear 40 are disengaged, making it easier to insert them.

In the figure, reference numeral 50 denotes a fuel tank, which stores gasoline fuel therein, and is configured so that the gasoline fuel can be fed into the engine 2 through a pipe 50a. Further, 51 is an exhaust treatment device.

Next, the operation of the gasoline engine car 1 will be explained.

First, plug 14 is connected to socket 13.
At this time, current flows from the battery to the nichrome wire 11 via the plug 14, socket 13, and connection member 12, and the nichrome wire 11 generates heat. Next, the starter 43 is inserted and pulled out to rotate the output shaft 2a. As a result, gasoline fuel is sucked into the engine 2 from the fuel tank 50, ignited by the heat generated by the nichrome wire 11, and the engine 2 is started. Then, the output shaft 2a rotates, and the flywheel 3 also rotates at high speed accordingly. Further, the rotational driving force of the output shaft 2a is appropriately decelerated by the gear group 4 and is transmitted to the front wheels 52 and the rear wheels 53 as described above, thereby driving both wheels. Note that since the nichrome wire 11 is heated by the heat generated by the ignition of vaporized gasoline, it is not necessary to keep the plug 14 connected after the engine is started. In addition, there is a socket 13 on the chassis 5.
However, a plug 14 may be provided on the chassis 5 and a socket 13 may be connected to the battery 16.

In the above embodiments, a case has been described in which a gasoline engine is used, but the present invention is not limited to a gasoline engine, and an engine using other fuels may be used.

[Effects of the invention] As explained above, according to the invention, since the plug-in connection device is detachably installed, the engine can be started easily without requiring any skill as in the past. Furthermore, it becomes possible for children to play easily.
