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, a saddle, and a wheel are arranged on a rotating wheel, and drive shafts each having pedals attached to the left and right are connected to each wheel via a one-way clutch. A rotary wheel rotation mechanism that allows the rotary ring to freely rotate is provided, and a rotary wheel reversal prevention mechanism that prevents the rotary wheel from reversing.

(Function) When you start pedaling the pedal 24 attached to the drive shaft 21, the axle 20 starts to rotate clockwise, for example, as shown in FIG. 6, via a one-way clutch consisting of a ratchet and a clutch. At the same time, the wheels 7 also start rotating in the same direction, and the rotating wheel 4 starts rotating about the central support 1 as shown in FIG.

While the rotating wheel 4 is rotating, the wheel 7 will rotate on the rail 9 even if someone does not pedal 24, but the rotation is not transmitted to the drive shaft 21, so the drive shaft 2
The pedals 24 attached to both left and right ends of the pedal 1 remain stationary. Therefore, it is safe to put your foot on the pedal 24.

On the other hand, even if an attempt is made to reverse the rotating wheel 4, the reversal prevention piece 19 of the rotating wheel reversal prevention mechanism 14
Since it engages with the saw teeth of No. 7, the rotating wheel 4 cannot be reversed. Therefore, it is safe even when the foot is placed on the pedal 24.

(Example) A first example of the present invention will be described with reference to FIGS. 1 to 7.

In the figure, 1 is a pipe-shaped central support,
A hollow rotating tube 2, which will be described later, is rotatably attached to the upper end of the hollow rotating tube 2, and a radial mounting rod 3 is attached to the hollow rotating tube 2.
Attach the rotating wheel 4 via the. In addition, the center pillar 1
The lower end of the unit shall be fixed to a fixed base installed underground.

At a predetermined location of the rotating wheel 4, one set includes a handle 5,
A plurality of sets of propulsion units 8 consisting of saddles 6 and wheels 7 are arranged at equal intervals. In addition, at the bottom of each wheel 7,
An annular rail 9 on which each wheel 7 runs is laid.

FIG. 3 is a sectional view showing the rotation mechanism of the rotating wheel 4. FIG.

As shown in the figure, there is a spherical surface 10 at the upper end of the center column 1.
Fix the hemisphere 10 with A. The upper end of the central support 1 is covered with a cylindrical hollow rotary cylinder 2 that closes the upper end 2A, and the inner surface of the upper end 2A contacts the spherical surface 10A of the hemisphere 10. At this time, there is a gap 1 at a predetermined interval between the center support 1 and the hollow rotating cylinder 2.
form 2. Due to this gap 12, the hollow rotating cylinder 2
is rotatable and tiltable. A plurality of small balls 13 made of iron or synthetic rubber are embedded in the outer peripheral surface of a central support 1 facing the inner peripheral surface of the lower end of a hollow rotary cylinder 2 so as to rotate on its axis.

Next, the rotating wheel reversal prevention mechanism 14 that prevents the rotating wheel 4 from reversing will be explained.

The rotational wheel reversal prevention mechanism 14 has a reversal prevention wheel 15 smaller than the rotational wheel 4, and is attached to the rotational wheel 4 via a mounting rod 16 so that it can rotate near the ground surface. Further, a plurality of serrated plates 17 each having a serrated cross section are arranged at predetermined intervals under the anti-reverse ring 15, and are fixed to the ground surface with a fixture 18.

As shown in FIG. 4, the anti-reversal wheel 15 pivotally supports a anti-reverse piece 19 that engages with the saw teeth of the serrated plate 17, and the anti-reverse piece 19 is always biased counterclockwise. The anti-reverse pieces 19 are attached to the anti-reverse ring 15 in correspondence to the number of serrated plates 17 arranged.

With the above configuration, when the reversal prevention piece 19 of the reversal prevention wheel 15 is engaged with the serrated plate 17,
Although it is possible to prevent the rotating wheels 4 from reversing, reversing cannot be prevented when they are not engaged. Therefore,
If it is desired to completely prevent the rotating wheel 4 from reversing, the sawtooth plate 17 may be placed over the entire lower part of the anti-reverse wheel 15 without being divided. Conversely, rotate wheel 4 by up to 1/2
When it is desired to reverse the rotation by 1/n rotation, such as 1/3 rotation, the number of serrated plates 17 may be increased by 2, 3, . . . n accordingly.

Next, the drive mechanism for the wheels 7 will be explained with reference to FIG.

The wheel 7 is attached to a hollow axle 20 as shown in FIG. 5, and a drive shaft 21 is inserted through the hollow axle 20. This drive shaft 21 is supported by a pair of frames 22, 22 hanging down from the rotating wheel 4, and a pair of pedals 2 are connected to the left and right ends of the drive shaft 21 via connecting rods 23.
Install 4 and 24.

As shown in FIG. 6, a ratchet 26 having a serrated cross section is formed on a part of the drive shaft 21 and engages with a click 25 supported on the inner periphery of the hollow axle 20. With the one-way clutch formed in this way,
Only when the drive shaft 21 is rotated in one direction as shown, the rotation of the drive shaft 21 can be transmitted to the wheels 7 attached to the axle 20.

Note that instead of the configuration shown in FIG. 5, a click 27 is pivotally supported on a part of the drive shaft 21 as shown in FIG.
may be formed on the inner periphery of the hollow axle 20 of the wheel 7.

In this configuration, when the infants sit on each saddle 6, grasp the handlebars 5, and begin to pedal the pedals 24, the drive shaft 21 begins to rotate clockwise as shown in FIG. As a result, the ratchet 26 formed on the drive shaft 21 engages with the click 25 provided on the axle 20 side, and the wheel 7
starts rotating in the same direction as the rotation of the drive shaft 21, so the wheels 7 start running on the rails 9. Along with this, the rotating wheel 4 moves to the first position around the center support 1.
Start rotating in the direction of the arrow as shown in the figure. As long as the pedal 24 is continued to be pedaled, the rotating wheel 4 rotates and each wheel 7 runs on the rail 9.

Furthermore, in parallel with the rotation of this rotary wheel 4, the anti-reverse wheel 15 rotates, and during the rotation, the anti-reverse piece 1
9 slides over the serrated plate 17 when it reaches it.

By the way, some young children do not pedal 24 or stop pedaling halfway through the process.
In such a case, the wheel 7 rotates clockwise on the rail 9 due to the propulsion of the other wheel 7, but
The rotation is not transmitted to the drive shaft 21 (see FIG. 6). Therefore, the pedal 24 fixed to the drive shaft 21 is in a stationary state, and even if the user puts his or her foot on the pedal 24, there is no danger and it is safe.

Furthermore, when a child gets inside the rotating wheel 4 and attempts to reverse the rotating wheel (in the direction opposite to the direction of the arrow in FIG. 1), the anti-reverse piece 19 attached to the anti-reverse wheel 15 For example, as shown in FIG. 4, it engages with the serrations of the serrated plate 17. Therefore, rotating wheel 4
may not reverse at all, or can only reverse by a maximum of 1/3 of a turn, so even if pedal 2
Even if there is someone putting their foot on the pedal 4, the pedal 24 will not be reversed more than necessary and it will be safe.

As described above, in the first embodiment, the rotary wheel reversal prevention mechanism 14 for preventing the rotary wheel 4 from reversing was configured as shown in FIG. 4, but instead of this, as shown in FIG. The rotating wheel reversal prevention mechanism 29 may also be used.

This rotating wheel reversal prevention mechanism 29 includes a reversal prevention piece 30 that is always biased counterclockwise on the outer periphery of the center column 1.
A ratchet 31 with a serrated cross section that engages with the reversal prevention piece 30 is provided on the inner periphery of the hollow rotary cylinder 2. As a result, the hollow rotary tube 2 can only rotate in one direction, so that the rotary wheel 4 can be prevented from reversing. If the pitch of the saw teeth in the ratchet 31 is changed as necessary, the rotating wheel 4 can be rotated in the reverse direction according to the pitch.

Next, a second embodiment will be described with reference to FIGS. 9 to 11.

Reference numeral 32 denotes a horizontal rotating wheel formed of a pipe, and at a predetermined location thereof, a plurality of sets of propulsion parts 8 each consisting of a handle 5, a saddle 6, and wheels 7 are arranged at equal intervals as in the first embodiment. Set up In addition, an annular rail 33 on which each wheel 7 runs is laid under each wheel 7 so as to be co-centered with the rotating wheel 32.

The drive mechanism for the wheels 7 is the same mechanism as shown in FIG. 5 described in the first embodiment, so the same reference numerals are given and the explanation thereof will be omitted.

Next, the rotation mechanism of the rotating wheel 32 will be explained with reference to FIG. 10.

A plurality of roll supports 34 are mounted downward at predetermined locations on the rotating wheel 32 at equal intervals, and each roll support 34 has a vertical axis of rotation at its lower end, as shown in FIG. The auxiliary roll 35 is rotatably attached. Further, a vertical auxiliary roll running path 36 on which each of the auxiliary rolls 35 rolls is provided integrally with the rail 33. At the upper end of the auxiliary roll running path 36, a regulating part 37 for preventing the rotary wheel 32 from coming off upward is installed over the entire upper end of the auxiliary roll running path 36 or at other areas excluding three predetermined areas. Provided for.

Next, the rotating wheel reversal prevention mechanism 38 that prevents the rotating wheel 32 from reversing will be explained with reference to FIG. 11.

Reference numeral 39 denotes a reversal prevention piece that is pivotally supported on the roll support 34 and always biased counterclockwise. A sawtooth section 40 having a serrated cross section that engages with the reversal prevention piece 39 is provided at the lower part of the regulating part 37. The sawtooth parts 40 may be provided over the entire lower part of the regulating part 37, or a plurality of sawtooth parts 40 may be provided at equal intervals below the regulating part 37.

In this configuration, when the infants sit on each saddle 6, grasp the handlebars 5, and begin to pedal 24, the wheels 7 begin to run on the rails 33, as in the first embodiment. Furthermore, in parallel with this, each of the auxiliary rolls 35 begins to roll on the auxiliary roll running path 36 provided integrally with the rail 33, and the reversal prevention piece 39 begins to slide on the sawtooth portion 40.

Therefore, as long as the pedal 24 is continued, the rotating wheel 32 is guided by each auxiliary roll 35 and moves along the rail 33.
Moreover, each wheel 7 does not come off the rail 33.

By the way, when an infant attempts to reverse the rotation wheel 32 (opposite to the direction of the arrow in FIG. 9), the reversal prevention piece 39 attached to the roll support 34 has a sawtooth shape as shown in FIG. 11, for example. It meshes with part 40. Therefore, the rotating wheel 32 does not rotate in reverse at all or can rotate only a small amount, so that even if someone is putting their foot on the pedal 24, the pedal 24 will not reverse and it is safe.

(Effect of the invention) As described above, in this invention, when the wheel rotates in one direction as the rotating wheel rotates, the one-way clutch prevents the rotation of the wheel from being transmitted to the drive shaft to which the pedal is fixed, and the wheel comes to a standstill. This has the effect that the child can play safely even if he or she does not pedal or does not pedal, and can play safely regardless of whether or not he or she has the ability to pedal.

In addition, we have installed a rotating wheel reversal prevention mechanism to prevent the rotating wheel from reversing, so even if a child tries to reverse the rotating wheel, the child will not be able to reverse the rotation, and even if he or she puts his or her foot on the pedal at that time, the pedal will reverse. It is completely safe.
