Description

A kind of baby walker

[technical field]

The utility model relates to a kind of baby walker.

[background technology]

In infant's developmental process, baby walker is to help the baby to enter the learning tool in walking stage from the stage of crawling, and infant sitting stands in the go-kart, is learning to keep standing position and moves with the strength of both legs by the help of go-kart.Study initial stage, the baby do not have control direct of travel ability, the time and forward, the time and backward, the time and left, the time and to the right, therefore its direction of advancing is unfixing, does not avoid advancing or the ability of the environment that averts danger towards the direction of danger certainly yet.

Traditional baby walker is haply by a seat that supports infant's health, be erected at the bracing frame of an annular frame in order to supporting chair, and several wheels that are installed in the bottom of framework are formed, the number of wheel might not, the four-wheel type that is distributed in four corners is arranged, and perhaps more six take turns pattern.The wheel of conventional baby go-kart can move towards direction arbitrarily all, without any restriction fully, without any brake device more, this design is breakneck for the baby of the ability of not controlling travel direction, what the producer of go-kart can advise all generally that the head of a family is careful when the baby uses go-kart looks after on the side, in fact still have many heads of a family can't accomplish this requirement really, and the baby is met accident.

In order to improve this shortcoming, at Chinese Taiwan patent announcement number is the structure that has disclosed a kind of go-kart in the 363375 patent cases, wherein the go-kart bottom is provided with an arc frame, arc frame two ends are provided with wheel, and support with a support portion in the middle section, make go-kart do directed rotation for axle in the support portion, move in certain scope and be limited in, yet such design structurally and built on the sand, and adjustment location, support portion design department is wherein inwardly depressed button, causes the danger of tong when adjusting easily.
