Description

The rotatable seat fixed structure of baby walker

The utility model relates to the rotatable seat fixed structure of a kind of baby walker, in order to rotatable seat is limited to the ad-hoc location of go-kart corresponding with it, makes it and can't rotate.

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 by the help of go-kart, and moves with the strength of both legs.At the initial stage of study, the baby does not have the ability of control direct of travel, the time and forward, the time and backward, the time and left, the time and to the right, its direction of advancing is uncertain, do not have to avoid advancing or the ability of the environment that averts danger towards the direction of danger.

Traditional baby walker is haply by a seat that supports infant's health, be erected at the bracing frame of a ring-like framework in order to supporting chair, and several wheels that are installed in the bottom of framework are formed, wherein 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, therefore be quite dangerous to the baby who does not have control action direction ability, so the producer of go-kart can advise all that generally the head of a family needs to look after aside when the baby uses go-kart, but in fact the head of a family can't take into account sometimes, causes the baby to meet accident.

For overcoming above-mentioned shortcoming, at Taiwan patent announcement the 363rd, disclosed a kind of go-kart structure in the 375 patent cases, wherein an arc frame is established in the go-kart bottom, arc frame two ends are provided with wheel, and sentence a support portion at interlude and support, and make go-kart do a directed rotation for axle in the support portion, only moving with the restriction baby walker in certain scope inward turning transfer, to guarantee baby's safety in use.But such design only can be moved the baby in a circular scope, make the baby feel dull easily, then designed a kind of baby walker again, have and to make the baby through the rotating disk of seat in the three-sixth turn of perambulator inward turning, this kind design is found in Taiwan patent announcement the 370th, 839 patent cases " structural improvement of go-kart ", dish has installed a ring-like bead for the rotating disc that is pivoted on go-kart, this rotating disc is by periphery wall, idle loop type chute among upper wall surface and internal perisporium constitute, wherein the bottom face of periphery wall contacts with end face on the last dish, and the below of perisporium is provided with the plurality of elastic convex clip within this rotating disc, for being held in perisporium below within the dish, wall offers the intercalation location of some jacks for some reference columns of cushion on this rotating disc in addition, makes this cushion rotatable, but the design of this kind baby walker, though make the baby be not easy to feel dull, but make the head of a family when the feeding baby, the baby can rotate arbitrarily, causes the inconvenience of head of a family's feeding.

The purpose of this utility model is to address the above problem, and provides a kind of baby walker rotatable seat fixed structure, in order to rotatable seat is limited on the ad-hoc location of go-kart corresponding with it, makes it and can't rotate.

For achieving the above object, the technical solution of the utility model is: the rotatable seat fixed structure of a kind of baby walker, be arranged at a baby walker that includes base and load bearing seat, this load bearing seat is provided with a rotating disk group and a seat that can rotate on this rotating disk group, it is characterized in that: this rotating disk group is provided with a lockset, and at least one corresponding with it groove is set at load bearing seat, when this lockset can be clamped in this groove, this rotating disk group and this seat can't be rotated.

Because the rotatable seat fixed structure of baby walker of technical solutions of the utility model, cooperatively interact by lockset and groove, realize padlock, difference in functionality such as padlock and automatic padlock not, therefore can select to allow the random rotary seat of child, avoid child's rotary seat to be threaded to a special angle or fix the ad-hoc location of seat in go-kart corresponding such as service plate district or toy district, so that head of a family's feeding or allow wholwe-hearted the playing of child with it with lockset.
