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, play equipment for children installed in parks and the like has mainly been swings, slides, horizontal bars, seesaws, etc., and there has been a desire for new play equipment to appear.

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, in the present invention, a plurality of supports are arranged at equal intervals around the outer periphery of a disc that can freely rotate around the center, a saddle and a handle are fixed above each support, and a wheel is connected below the support. , a pedal is attached to the axle of the wheel via a one-way clutch.

(Function) Now, when infants want to sit on each saddle 8 before use, since each support body 5 is separated and independent, it is possible to do so from any of the inside, outside, or rear.

When you sit on the saddle 8 and start pedaling the pedals 14 attached to the drive shaft 11, the axle 1
0 starts rotating clockwise as shown in FIG. 3, and along with this, the wheel 6 also starts rotating in the same direction, causing the disc 3 to rotate around the central axis 1 as shown in FIG. Start rotating.

While the disc 3 is rotating, the wheel 6 rotates on the ground even if no one pedals the pedals 14, but the pedals 14 attached to both left and right ends of the drive shaft 11 remain stationary. Therefore, it is safe to put your foot on the pedal 14.

Furthermore, even if children other than the user get on the disc 3 during its use, there is no particular danger and there is no problem with its use.

It should be noted that when the disc 3 is in a stationary state, the infant cannot rotate each support body 5 at high speed as long as the child rests on the disc 3, which is very safe.

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

Reference numeral 1 denotes a central shaft which is rotatable by being supported on a bearing (not shown), and a plurality of rotary rods 2 are attached horizontally and radially to this central shaft 1. 3 is a disk that rotates together with each rotary rod 2 around the central axis 1;
It is fixed to the upper side of each rotating rod 2. 4 is a reinforcing pipe when fixing the disk 3 to each rotary rod 2. A ring-shaped handrail 9 is provided on the disc 3 so that the child can hold onto it.

The tip side of each rotary rod 2 is bent upward, and each support body 5, which rotates around the central axis 1 and has an arc shape, for example, is attached to the upper end of the bent portion. A saddle 8 and a handle 7 are fixed above each support 5, and a wheel 6 is connected below. Note that a rail (not shown) on which the wheel 6 runs may be laid under the wheel 6.

Next, the drive mechanism for the wheels 6 will be explained with reference to FIG.

The wheel 6 is attached to a hollow axle 10 as shown in FIG. 2, and a drive shaft 11 is inserted through the hollow axle 10. The drive shaft 11 is supported by a pair of frames 12, 12 hanging down from the support 5, and a pair of pedals 1 are connected to the left and right ends of the drive shaft 11 via connecting rods 13.
Install 4 and 14.

A ratchet 16 having a serrated cross section is formed on a portion of the drive shaft 11, as shown in FIG. With the one-way clutch formed in this way,
Only when the drive shaft 11 is rotated in one direction as shown, the rotation of the drive shaft 11 can be transmitted to the wheels 6 attached to the axle 10.

Note that instead of the configuration shown in FIG. 3, a click 17 is pivotally supported on a part of the drive shaft 11 as shown in FIG.
may be formed on the inner periphery of the hollow axle 10 of the wheel 6.

In addition, as shown in FIG. 1, each rotary rod 2 is attached to a freely rotatable central shaft 1, but instead of this, as shown in FIG. 5, it is attached to a hollow rotary cylinder 20 configured to be freely rotatable. You can do it like this.

That is, the hollow rotary cylinder 20 has its upper end closed to form a closed part 21, and the inner surface of the closed part 21 is in constant surface contact with the spherical surface of the hemispherical body 23 fixed to the upper end of the central support 22. Post 22
The upper end of the machine is coated to make it rotatable. Further, a plurality of small balls 24 made of iron or the like are embedded in the outer circumferential surface of the central column facing the inner circumferential surface of the lower end of the hollow rotary cylinder 20 so as to rotate on its axis.

In such a configuration, when infants try to sit on each saddle 8 prior to use, they can sit on each saddle 8 from inside, outside, or from the rear of each support 5, so that infants can sit on each saddle 8 according to their own ability. You can choose one of them depending on the situation and sit on each saddle 8.

When the children sit on each saddle 8, grip the handlebar 7, and begin to pedal 14, the drive shaft 11 begins to rotate clockwise as shown in FIG. As a result, the ratchet 16 formed on the drive shaft 11 engages with the click 15 provided on the axle 10 side, and the wheels 6 begin to rotate in the same direction as the rotation of the drive shaft 11, so that the wheels 6 begin to travel on the ground. Along with this, the rotating rod 2 and the disc 3 begin to rotate about the central axis 1 in the direction of the arrow as shown in FIG. As long as the pedal 14 is continued, each wheel 6 travels on the ground.

By the way, some young children do not pedal 14, or some children stop pedaling halfway through the process.
In such a case, the wheel 6 rotates clockwise on the ground due to the propulsion of the other wheels 6, but the rotation is not transmitted to the drive shaft 11 (see FIG. 3).
Therefore, the pedal 14 fixed to the drive shaft 11
is in a stationary state, and even if the foot is placed on the pedal 14, there is no danger and it is safe.

Furthermore, even if children other than the user get on the disc 3 during its use, there is no particular danger and there is no problem with its use. At this time, the children can put their hands on the handrail 9, so they can play more safely.

(Effects of the invention) As described above, in this invention, when the wheel rotates in one direction as the disk 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, in this invention, since the support is rotated by interposing a disk between the rotation center and the support, the support cannot be rotated at high speed when the infant is on the disk. Furthermore, even if a child other than the user gets on the disc while the support is rotating, it is not particularly dangerous and there is no problem with its use, allowing the player to play safely.

Furthermore, in the present invention, a plurality of supports are arranged at equal intervals around the outer periphery of the disk so that each support is separated,
Since this is equipped with a saddle, when trying to sit on each saddle, it is possible to sit from inside, outside, or from the rear of the support, allowing infants to choose one according to their own abilities. You can sit on the saddle.
