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 spherical surface is formed at the upper end of the center column, and the spherical surface and the upper end of the center column are covered with a hollow rotating cylinder whose upper end is closed, and a rotating ring is connected to the rotating tube via a radial mounting rod. Install the
A plurality of pairs of handles, saddles, and wheels are arranged at equal intervals on the rotating wheel, and pedals are attached to both left and right ends of a drive shaft that passes through the hollow axle of each wheel, and pedals are attached to the left and right ends of the drive shaft that passes through the hollow axle of each wheel. It is equipped with a one-way rotating clutch.

(Function) Now, when the pedals 16 provided on both sides of each frame 15 and attached to the drive shaft 14 are started to be pedaled, the axle 18 is rotated clockwise through a one-way rotating clutch consisting of a ratchet and a crank, for example, as shown in FIG. Along with this, the wheel 6 also starts rotating in the same direction, and the rotating wheel 2 starts rotating about the central support 1 as shown in FIG.

While the rotating wheel 2 is rotating, the wheel 6 will rotate on the rail 8 or on the ground even if someone does not pedal the pedal 16, but the rotation is not transmitted to the drive shaft 14.
The pedals 16 attached to both left and right ends of the drive shaft 14 remain stationary. Therefore, it is safe to put your foot on the pedal 16.

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

Reference numeral 1 designates, for example, a pipe-shaped central support, and a rotary ring 2 is attached to a hollow rotating tube 11 covering the upper end of the central support via a mounting rod 3, and the lower end of the center support 1 is attached to a fixed base or the like installed underground. Fixed to. A plurality of sets of handles 4, saddles 5, wheels 6, etc. are arranged at predetermined locations on the rotating wheel 2 at equal intervals. Also,
A rail 8 on which the wheel 6 runs is laid under the wheel 6.

FIG. 3 is a sectional view showing how the rotary ring 2 is attached to the center support 1. As shown in FIG.

As shown in the figure, a spherical surface 9A is attached to the upper end of the center support 1.
A hemisphere 9 having a shape is fixed. The upper end of the central support 1 is covered with a cylindrical rotating cylinder 11 that closes the upper end 10, and the inner surface of the upper end 10 is brought into contact with the spherical surface 9A of the hemisphere 9. At this time, a space 12 with a predetermined interval is formed between the center support 1 and the hollow rotary cylinder 11. This space 12 allows the rotary cylinder 11 to freely rotate and tilt as will be described later. Rotating tube 11
A plurality of small balls 13 made of iron or synthetic rubber are embedded in the outer circumferential surface of the central support 1 opposite to the inner circumferential surface of the lower end thereof so as to rotate. In addition, the rotary cylinder 11 includes
A rotating shaft 2 is fixed via a radial mounting rod 3.

FIG. 4 is a sectional view showing a transmission device between a pedal and an axle according to this embodiment.

In the figure, the drive shaft 14 is supported by a pair of left and right frames 15, 15, and connecting rods 17 are attached to both ends of the drive shaft 14.
A pair of left and right pedals 16, 16 are fixed to each other through. The frames 15, 15 have their upper ends fixed to the rotating wheel 2. Further, a hollow axle 18 of the wheel 6 is inserted through the drive shaft 14 .

A ratchet 20 having a serrated cross section is formed on a portion of the drive shaft 14, as shown in FIG. The one-way rotating clutch formed in this way allows rotation of the drive shaft 14 to be transmitted to the wheels 6 only when the drive shaft 14 is rotated in one direction as shown.

Note that instead of the configuration shown in FIG. 5, a click 21 is pivotally supported on a part of the drive shaft 14 as shown in FIG.
may be formed on the inner periphery of the hollow axle 18 of the wheel 6.

The rail 8 has an L-shaped cross section as shown in FIG. 7, and is fixed to the ground by a fixing fitting 23.

In this configuration, when the infants sit on each saddle 5, grasp the handlebars 4, and begin to pedal the pedals 16, the drive shaft 14 begins to rotate clockwise as shown in FIG. As a result, the ratchet 20 formed on the drive shaft 14 engages with the click 19 provided on the axle 18 side, and the wheel 6
begins to rotate in the same direction as the rotation of the drive shaft 14, so the wheels 6 begin to run on the rails 8. Along with this, the rotating wheel 2 rotates around the center support 1 at the first position.
Start rotating in the direction of the arrow as shown in the figure. As long as the pedal 16 is continued to be pedaled, the rotating wheel 2 rotates and each wheel 6 runs on the rail 8.

By the way, there are some children who cannot pedal 16 or who stop pedaling halfway through the process.
In such a case, the wheel 6 rotates clockwise on the rail 8 due to the propulsion of the other wheels 6, but
The rotation is not transmitted to the drive shaft 14 (see FIG. 5). Therefore, the pedal 16 fixed to the drive shaft 14 is in a stationary state, and there is no danger and it is safe to put your foot on the pedal 16.

In addition, since the space 12 is provided between the center support 1 and the hollow rotating tube 11, the rotating tube 11 can be tilted, and the rotating ring 2 integrated with the rotating tube 11 can not only be rotated freely but also It can be tilted freely. Therefore, for example, if a pebble or the like falls on the rail 8, the rotary cylinder 11 integrated with the rotary wheel 2 rotates at an angle depending on the pebble. Due to this inclination, even when the inner circumferential surface of the lower end of the rotary cylinder 11 comes into contact with the small ball 13 of the central support 1, the frictional force is small, so the rotation of the rotary cylinder 11 is not hindered, and the rotary ring 2 It can rotate smoothly and stably.

In addition, in this embodiment, as shown in FIG.
Although the inner surfaces of the upper end 10 are brought into direct contact, a spring (not shown) may be interposed between the hemisphere 9 and the inner surface of the upper end 10. In this way, even if the tires are worn out, the rotating wheels 2
moves down against the elasticity of the spring, and the wheel 6 moves to the rail 8.
It has the advantage of being able to run smoothly on top. Also,
The hemisphere 9 may be replaced with a sphere such as a steel ball.

In addition, in this embodiment, the rotating ring 2 and its mounting rod 3 are integrally formed as shown in FIG. It may be configured such that it is divided at the location and each divided piece is connected with the male thread 27 and female thread 28. With this configuration, the rotary ring 25 and its mounting rod 26 can be disassembled and transported to the installation site and assembled there, so there is an advantage that transportation is easy, especially for large ones.

(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, in this device, the rotating wheels are freely rotatable and tiltable relative to the central support, which has the effect of allowing the rotating wheels to rotate stably and smoothly even when the wheels are running on uneven ground.
