[Problems to be solved by the invention]
By the way, it is often seen that parents are taking a walk or playing in a park with an infant on an infant vehicle such as an infant bicycle, an infant tricycle, or an infant car. Also, you can often see a shopping trip with an infant on an infant bicycle.
[0012]
At this time, if there is a difference between the speed of the infant riding on the infant vehicle and the speed of the guardian's walking, the guardian sometimes runs, returns, or turns back, and the infant is in an accident if it is not always near the infant. There is a risk of encounter. Even parents are struggling and using physical strength, especially on slopes. In addition, when the infant gets tired, it is necessary for the guardian to push it from behind.
[0013]
Also, when playing in the park, the parents push the infant vehicle on which the infant rides from behind to make the child more enjoyable or practice driving, so that there are more opportunities for parent-child contact through the infant vehicle Is also necessary.
[0014]
Here, in the infant vehicle equipped with a guardian's handle from the lower back to the rear upper part, the infant can get on the tricycle and the guardian can walk together while pushing with one hand from behind. , Because the parents push the infant vehicle on the park in the park from behind to make the child more enjoyable and parent-child contact, parents do not have to bend, so the advantage of not getting tired is there.
[0015]
However, in infant vehicles equipped with this type of guardian's handle, the guardian inadvertently removes his hand from the guardian's handle while speaking while stopping the tricycle carrying the infant on the slope. Or, when you change your hand baggage to the other hand, the tricycle will naturally go down the slope, sometimes increasing its momentum, causing the infant to be extremely dangerous.
[0016]
Therefore, in order to solve these problems, the present inventor needs a brake that allows the guardian to operate from the back of the infant vehicle in a natural standing posture from behind the infant vehicle. I thought. The steering device for a guardian with a brake according to the present invention has been invented under such a background. The inventor has also tried various devices for providing this apparatus to infant bicycles such as infant bicycles, infant tricycles, and infant automobiles.
[0017]
The present invention, which has been completed through such circumstances, is used by being attached to an infant vehicle such as an infant bicycle, an infant tricycle, an infant car, etc. It is possible to move forward while pushing with one hand while walking in a natural standing posture, and it is possible to operate the brake by the hand of the guardian, protecting the infant on the infant vehicle The parent can move the infant vehicle according to his / her walking speed, and the guardian can operate by pushing from the back while driving in the natural standing position, and can practice driving.
