Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small and lightweight automatic play equipment which can be easily used on a dirt road surface with a feeling similar to a skateboard.

[0002]

2. Description of the Related Art A skateboard is known as a play equipment which is played by a user standing and standing on a board with rollers to which the running force is imparted by kicking the road surface. Snowmobiles are known to do.

[0003]

[Problems to be solved by the invention] The use of a skateboard cannot be used unless the road surface is paved with concrete or the like, so there are restrictions on the place of use and the running speed of the skateboard depends on the user's ability to kick the road surface. Since there is a dependency, there will be individual differences depending on age and gender. Further, since the latter snowmobile is limited to use only on snow, there is a limitation due to the season and there is a problem that it is not common as a playground equipment.

[0004]

[Means for Solving the Problems] The present invention is to provide an automatic play equipment which can be driven by a small prime mover and can easily enjoy a skateboard- like sensation even on an unpaved road surface. Using rubber tires for the front and rear wheels, the front and rear wheels are rotatably held by separate support frames, the front and rear support frames are connected by connecting pipes, and the handle shaft is attached to the front support frame. In addition, the handle shaft is mounted so as to be able to be tilted up and down, and the handle shaft is formed by a large-diameter pipe portion and a small-diameter pipe portion so that the length of the handle shaft can be adjusted. Is mounted, the outer periphery of the prime mover is covered with a seat that also serves as an engine cover, and a footrest is mounted on the connecting pipe so as to be able to roll at a predetermined angle.

[0005]

Since the handle shaft portion 6 can be tilted up and down with the pin shaft 7 as a fulcrum, it is not bulky when folded, which is convenient for carrying and the protruding length of the handle shaft portion can be adjusted. By adjusting the height of the steering wheel, you can maneuver while standing and sitting.

Since the footrest can be tilted at a predetermined angle with the connecting pipe as an axis, it has a function of training a sense of balance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing the embodiments of the present invention, in FIG. 1, 1 is a front wheel made of rubber tire, 2 is a rear wheel made of rubber tire, and front wheel 1 and rear wheel 2 Are rotatably held individually by the support frames 3 and 4, respectively. The front and rear support frames 3 and 4 are connected by a connecting pipe 5.

A lower end portion of a handle shaft portion 6 is provided with a pin shaft 7 on a front support frame 3 which rotatably holds a front wheel 1.
Therefore, it is pivotally supported so that it can be pulled up and down. When the handle shaft portion 6 stands up, the handle shaft portion 6 is
A lock cylinder 8 having a length extending over the lower portion of the handle shaft portion 6 and the upper portion of the support frame 3 with the pin shaft 7 interposed is slidably fitted in the vertical direction.

The handle shaft portion 6 is a large diameter pipe portion 6
The small-diameter pipe portion 6B is slidably inserted into the large-diameter pipe portion 6A, which is composed of A and a small-diameter pipe portion 6B and is pivotally supported by the support frame 3 portion by the pin shaft 7. In addition, the handle height can be adjusted by adjusting the insertion length position of the small diameter pipe portion and tightening and fixing it with the fastener 9 provided on the upper portion of the large diameter pipe portion 6A. Has been done.

A small gasoline engine 10 used in a lawn mower or the like is mounted on a support frame 4 of the rear wheel 2, and the rear wheel 2 extends from the output shaft of the engine to a reduction gear mechanism, a belt chain, It is driven through a known appropriate transmission means such as a roller friction or a centrifugal clutch. 1
Reference numeral 1 is a fuel filler port, 12 is a fuel tank, 13 is a spark plug, and 14 is a starting rope.

The outer periphery of the gasoline engine 10 is covered with an engine cover / seat 15 that can also be used as a seat. The prime mover for driving the rear wheels is not limited to the gasoline engine, and may be, for example, a battery power source,
A glow engine or the like may be adopted.

On the connecting pipe 5, a footrest 16 having an anti-slip means on its upper surface is mounted by a supporting metal fitting 17 so as to be rotatable around the connecting pipe. Reference numeral 18 is a protrusion provided on the back surface of the foot rest 16, and 19 is a stopper provided on the connecting pipe or the support fitting. When the protrusion 18 contacts the stopper 19, the foot rest It is designed so that it will not tilt any further.

To explain how to use the automatic play equipment of the present invention, the handle shaft 6 of the handle 20 which is folded as shown by the alternate long and short dash line in FIG. The body 8 is fitted across the pin shaft 7 between the upper portion of the support frame 3 and the large diameter pipe portion 6A of the handle shaft portion 6 to fix the handle shaft portion. Then, with the stand 21 standing upright, the starting rope 14 is pulled to start the gasoline engine.

Next, the stand 21 is detached, one foot is placed on the footrest 16, and the accelerator lever 22 is operated to run the leg. The deceleration and stop during traveling are performed by operating the brake lever 23.

After use, the engine stop button 24 is pushed to stop the rotation of the gasoline engine, and then the stand 2
Set 1.

At the time of carrying or storing, the lower end of the locking cylinder 8 is moved above the pin shaft 7 to release the lock, and the handle is tilted with the pin shaft 7 as a fulcrum.

[0017]

EFFECTS OF THE INVENTION The present invention is compact and lightweight, and the handle shaft can be tilted up and down, and the length of the handle shaft can be adjusted to be short or long, which makes it easy to carry and saves space during storage. Therefore, for example, if you carry it in the trunk of an automobile, you can easily use it as a play tool similar to a skateboard or as a walking vehicle in the vicinity after you arrive at your destination.

Since the length of the handle shaft can be adjusted to be short or long,
When the length of the handle shaft is shortened as shown by the alternate long and short dash line in Fig. 1, in addition to maneuvering in a standing position, the engine cover should be used as a seat while seated in a seated position to grip the handlebars. You can

Since the footrest can be tilted at a predetermined angle,
The user can drive and operate while balancing with his / her feet as if he / she is using a skateboard, which greatly contributes to improving the sense of balance.

Further, since the front and rear wheels are made of rubber tires and are constructed so that they can be driven by a prime mover, they can travel without trouble even if the road surface is unpaved.
