Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a track toy that has a drive wheel located along the center line of the bottom of the toy body and that rotates the drive wheel to make the toy travel.

(Prior art and its problems) Generally, in a track toy that runs on two parallel tracks, wheels are fixed to both ends of the drive axle, so when the drive axle rotates, the wheels follow the rotation. The rotation speed of the drive wheels on both sides is the same,
Since the train tries to proceed in a straight line even when passing through a curved part of the track, there is a problem in that it is easy to run off the track. For this reason, it is necessary to attach the drive axle so that it can rotate in the horizontal direction with respect to the chassis so that the direction of the drive wheel can be changed depending on the curved state of the rail. However, if the drive axle is designed to be horizontally rotatable and then driven to rotate, there are problems in that the structure of the drive mechanism becomes complex, heavy, and expensive.

(Purpose of the invention) The present invention solves the above-mentioned problems.In particular, by rotating the drive wheel provided at the center of the bottom of the toy body instead of the wheels on the rail, it can run smoothly and has a simple structure. The purpose is to propose a track toy that is lightweight and can be produced at low cost.

(Means for achieving the object) In order to achieve the above object, the rail toy according to the present invention is a rail toy that has a drive mechanism using a spring and runs on parallel rails, and has the following requirements. It is characterized by

(a) Wheels are provided on both the left and right sides of the rail toy main body, and a drive wheel linked to the drive mechanism is provided at a position along the center line of the bottom of the rail toy main body.

(b) A track portion on which the drive wheel is placed is formed in the middle of the rail on which the wheel is placed.

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

The symbol A indicates the rail toy according to the present invention,
This rail toy A has a drive mechanism a inside a rail toy main body 1, and chassis 3, 3 on which wheels 4, 4, 4, 4 are attached to the front and rear of the bottom 2 of the rail toy main body 1.
is provided. The chassis 3, 3 are attached at their center portions to the bottom 2 of the tracked toy main body 1 so that they can freely rotate in left and right directions using mounting members 5, 5 such as screws as fulcrums. In this case, in order to limit the rotation of the chassis 3, 3 to a certain range, a stopper member (not shown) is erected at an appropriate position within the rotation range of the chassis 3, 3 to restrain it. Good too. Reference numeral 6 indicates a drive wheel provided at the center of the bottom 2 of the track toy main body 1. It is linked to mechanism a. The drive mechanism a is configured to transmit the driving force of a mainspring to the drive wheel 6 through a plurality of gears, and its main parts are unitized. The mainspring is wound up by the driving wheel 6, and the driving force thereof is directly transmitted to the drive mechanism so that the rail toy main body 1 can run.

On the other hand, the rail body 1 that runs the rail toy body 1
0 has a pair of rails 11, 11 formed on its upper surface, and in the middle between these rails 11, 11 is a track section 12 on which the drive wheel 6 provided on the bottom 2 of the rail toy main body 1 is placed. It is formed. Reference numeral 13 denotes a starting platform, and the starting platform 13 has a surface portion 14 that slopes downward from the rear end toward the front end, and is tapered. Furthermore, guide protrusions 1 are provided at both ends of the surface portion 14 over the entire longitudinal length thereof.
5 and 15 are integrally formed in a protruding manner. Furthermore, the tips of the guide protrusions 15, 15 are formed to have the same width as the width between the pair of rails 11, 11 formed on the upper surface of the rail main body 10, and the surface portion 14 of the starting platform 13 below the guide protrusions 15, 15 is Cutout part 1
6 is provided. And the above-mentioned rail body 10
When the starting platform 13 is engaged with the starting platform 13, as shown in FIG. The tips of the guide protrusions 15, 15 are mounted and engaged with the rails 11, 11.

Next, the manner in which the track toy A having the above configuration is used will be explained.

First, the rail toy main body 1 is connected to the rail 1 of the rail main body 10.
1 and 11, the driving wheel 6 formed on the bottom part 2 of the rail toy main body 1 is placed on the track section 12 provided in the center between the rails 11 and 11. Ru. And this rail 11,1
By moving the track toy main body 1 backward while holding it by hand, the drive wheel 6 rotates in the opposite direction, thereby forming a drive mechanism a provided inside the track toy main body 1 that is linked to the drive wheel 6. When you wind up the mainspring and release your hand, the driving force is directly transferred to the drive mechanism a.
It is possible to travel on the rails 11, 11. When running, the wheels 4, 4, 4, 4 on the rails 11, 11 also rotate, so from the outside it looks like the rail toy A is running due to the rotation of the wheels 4, 4, 4, 4, which makes it feel strange. There is no. Moreover, when the rail toys 11, 11 are curved, the chassis 3, 3 rotate according to the state of the curve, so that running is smooth. On the other hand, since the drive wheel 6 is provided at the center of the bottom of the rail toy main body 1, it is not affected by the curve of the rails 11, 11. Further, since the drive wheel 6 is made of soft synthetic rubber or the like, its contact resistance with the raceway portion 12 is large, and loss due to slipping can be prevented. Further, when the rail toy main body 1 is placed on the surface portion 14 of the starting platform 13 and is run, the guide ridges 15, 15 provided at both ends of the surface portion 14 allow the vehicle platform 3, The three wheels 4, 4, 4, 4 can be reliably guided and guided to the rails 11, 11 of the rail body 10. In the above embodiment, the drive wheel 6 may be provided along the center line of the bottom portion 2 of the rail toy main body 1, and may be provided, for example, at the front or rear portion of the chassis.

(Operations and effects of the invention) As described above, according to the invention, the wheels of the rail toy main body are placed on the rails, and the drive wheels of the toy main body are placed on the tracks, and the wheels are driven by the drive mechanism. When the ring is rotated, the track toy itself moves. At this time, the wheels rotate, so there is no discomfort seen from the outside. In addition, since the drive wheels are installed along the center line of the bottom of the tracked toy, they rotate smoothly along the track even when the track curves, and are not affected by curves, reducing the risk of the wheels falling off. It can run well without any problems. Furthermore, the drive mechanism only needs to be configured to rotationally drive the drive wheels, and there is no need to change the direction of the drive wheels.
The overall structure is simple, lightweight, and can be produced at low cost.
