Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a novel rotating vehicle play equipment that can be installed in parks, amusement parks, nursery schools, kindergartens, etc., and can be played by a plurality of infants, children, etc.

(Prior Art) Conventionally, the play equipment for children installed in parks and the like has mainly been swings, slides, horizontal bars, seesaws, etc., and the appearance of new play equipment has been desired.

Therefore, an object of the present invention is to provide a rotating vehicle play equipment that allows a plurality of infants and children to play bicycles simultaneously and safely according to their abilities.

(Means for solving the problem) In order to achieve the above object, the present invention has the following configuration.

That is, a plurality of propulsion parts each consisting of a handle, saddle, and wheels are arranged on a horizontal rotating wheel,
Drive shafts with pedals attached to the left and right are connected to each wheel via a one-way clutch, and an annular rail on which each wheel runs is laid in the same center as the rotating wheel. A plurality of auxiliary rolls having vertical rotation axes are attached thereto, and a vertical auxiliary roll running path on which the auxiliary rolls roll is integrally provided on the rail.

(Function) Now, when you start pedaling the pedals 11 attached to the left and right sides of the drive shaft 8, the wheel 7 is rotated, for example, to the fourth
As shown in the figure, the wheel 4 starts rotating clockwise, and the wheels 4 also start rotating in the same direction. Furthermore, in parallel with this, each auxiliary roll 17
The roller begins to roll on the auxiliary roll running section 18 provided at

As a result, as long as the pedal 11 is continued, the rotating wheel 1 is guided by each auxiliary roll 17 and the rail 6
The wheels 4 rotate smoothly on the rails 6, and each wheel 4 does not come off the rail 6.

Also, while the rotating wheel 1 is rotating, the wheel 4 will rotate on the rail 6 even if no one pedals the pedal 11.
Since the rotation is not transmitted to the drive shaft 8, the pedals 11 attached to both left and right ends of the drive shaft 8 remain stationary. Therefore, it is safe to put your foot on the pedal 11.

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

1 is a horizontal rotating ring formed by a pipe,
At the designated locations, one set includes a handle 2 and a saddle 3.
A plurality of sets of propulsion units 5 each consisting of wheels 4 are arranged at equal intervals. Furthermore, an annular rail 6 on which each wheel 4 runs is laid under each wheel 4 in the same center as the rotating wheel 1.

The wheel 4 is attached to a hollow axle 7 as shown in FIGS. 2 and 3, and a drive shaft 8 is attached to the hollow axle 7.
Insert. This drive shaft 8 is supported by a pair of frames 9, 9 hanging from the rotating wheel 1, and a pair of pedals 1 are connected to the left and right ends of the drive shaft 8 via connecting rods 10.
Install 1 and 11.

As shown in FIG. 4, a ratchet 13 having a serrated cross section is formed on a part of the drive shaft 8 and engages with a click 12 supported on the inner periphery of the hollow axle 7.
With the one-way rotating clutch formed in this way,
Only when the drive shaft 8 is rotated in one direction as shown, the rotation of the drive shaft 8 can be transmitted to the wheels 4 attached to the axle 7.

Note that instead of the configuration shown in FIG. 4, the click 14 is supported by a part of the drive shaft 8 as shown in FIG.
A ratchet 15 with which the click 14 engages may be formed on the inner periphery of the hollow axle 7 of the wheel 4.

In addition, as shown in FIG. 1, a plurality of roll supports 16 are attached to predetermined locations of the rotating wheel 1 at equal intervals facing downward, and each lower end of each of the roll supports 16 is attached to a predetermined location of the rotating wheel 1, as shown in FIG. As shown in the figure, an auxiliary roll 17 with a vertical axis of rotation is rotatably mounted. Further, a vertical auxiliary roll running path 18 on which each of the auxiliary rolls 17 rolls is provided integrally with the rail 6. At the upper end of the auxiliary roll running path 18, a regulating part 19 for preventing the rotary wheel 1 from coming off upward is installed over the entire upper end of the auxiliary roll running part 18 or at other areas excluding three predetermined parts. Provided for.

In this configuration, when the infants sit on each saddle 3, grasp the handlebars 2, and begin to pedal the pedals 11, the drive shaft 8 begins to rotate clockwise as shown in FIG. This results in
The ratchet 13 formed on the drive shaft 8 engages with the click 12 provided on the axle 7 side, and the wheels 4 begin to rotate in the same direction as the rotation of the drive shaft 8, so that the wheels 4 begin to travel on the rails 6. Furthermore, in parallel with this, each of the auxiliary rolls 17 starts rolling on an auxiliary roll running path 18 provided integrally with the rail 6.

Therefore, as long as the pedal 11 is continued to be pedaled, the rotating wheel 1 is guided by each auxiliary roll 17 and rotates on the rail 6, and each wheel 4 does not come off the rail 6.

By the way, some young children do not pedal 11 or stop pedaling halfway.
In such a case, the wheel 4 rotates clockwise on the rail 6 due to the propulsion of the other wheel 4, but
The rotation is not transmitted to the drive shaft 8 (see FIG. 4). Therefore, the pedal 11 attached to the drive shaft 8 is in a stationary state, and there is no danger and it is safe to put your foot on the pedal 11.

Note that while the rotary wheel 1 is rotating, a considerable centrifugal force acts on each operator, which may cause the operator to fall off. Therefore, in order to prevent this risk, it is preferable that the outside of the saddle 3 be sloped higher than the inside, or that the outside portion of the handle 2 be extended rearward.

(Effects of the invention) As described above, in this invention, when the wheel rotates in one direction as the rotating wheel rotates, the one-way rotating clutch prevents the rotation of the wheel from being transmitted to the drive shaft to which the pedal is fixed. Since it is in a stationary state, it is possible to play safely even when the pedals are not pedaled or not pedaled, and it has the effect that it can be played safely regardless of whether or not the child has the ability to pedal. .

In addition, an auxiliary roll is attached to the rotating wheel, and an auxiliary roll running section on which the auxiliary roll rolls is integrally provided on the rail, so the rotating wheel can be rotated without the need for a special support that serves as the center of rotation of the rotating wheel. It has the effect of rotating smoothly on the rails and preventing the wheels from coming off the rails.
