Description
Technical field
The present invention relates to a kind of children's seat, this children's seat has the adjustable for height characteristics of seat board.
Background technology
The seat that a lot of different types of adjustment heights are arranged on the present stage market, but these seats all are adult or infant's design, be not the children in 3-10 year or the seat of adult's design of short and small stature, continuous growth along with children, no longer need father and mother's feeding, the seat of the adjustment height that the infant is used is in being fit to them, the children in 3-12 year generally have a meal with sitting one with the adult, but the height of seat of adult's usefulness is too low, be not suitable for them, they only have the station on the seat, and the children of this age bracket are very active, and are therefore very dangerous.The child height of this age bracket changes greatly, can partly solve such problem although buy respectively the seat of differing heights, and is but very uneconomical.
Chinese invention patent ZL200810129284.9 discloses a kind of high chair, and described high chair can convert various structures to so that multiple use to be provided.Described high chair comprises a children's seat, and described children's chair has a seat element that is connected to Z-shaped framework.To such an extent as to a spare seat comprises that a described seat element of seat chair back of lying that is installed on the described seat element is inserted in the described spare seat.On the described spare seat with locked instrument described spare seat is fixed on the described seat element.But to such an extent as on the bottom described spare seat application standard chair that base element that separates also is inserted in described spare seat.Described pallet can be installed on the spare seat so that pallet and spare seat together use no matter whether spare seat is configured on the high chair and still is not configured on the high chair.Thereby described Z-shaped framework is provided with telescopic support legs and regulates height for high chair.But this Tallboy chair structure is firm not, easily topples over because rock, and is not suitable for the children of 3-12 year movability.
Chinese invention patent ZL200610121314.2 discloses a kind of mixed chair, and mixed chair of the present invention is the chair as children-oriented, has the chair of the strong point of rotating chair and wooden chair concurrently, and seat board is by (3 supportings of a pillar.The Height Adjustment of seat board can be by operating operating grip, easily carrying out under the effect of cylinder.On the other hand, the structure of pin substrate, a pair of bar and backboard adopts the mode of existing wooden chair, has realized as a whole the structure that has good stability.So, mixed chair form the strong point of the strong point that obtains existing rotating chair and wooden chair and construct be novel make.But this mixed chair complex structure, cost is higher, and when the seat board setting position was higher, up-to-date style was easily toppled over, and did not have handrail, was unfavorable for child protection.
Chinese invention patent ZL200610035480.0 discloses a kind of lifting children chair, its with the support of " people " font as the chair leg, be provided with the seat support and the backrest that are positioned on adult's seat between the chair leg, described chair leg top is provided with the handrail that is connected on the backrest, handrail extends to the backrest rear, its inboard, rear is provided with the locking device that can be clamped on adult's chair back, be provided with the pneumatic spring lowering or hoisting gear on the described seat support, the pneumatic spring lowering or hoisting gear passes seat support and is connected with the lifter plate that is positioned at seat bottom, the front end of described left handrail is movably installed with railing, railing can be overlapped on the front end of right handrail, the railing middle part is pressed on the top of pneumatic spring lowering or hoisting gear, is provided with the switch that can start by railing the pneumatic spring lowering or hoisting gear on the described right handrail; This design effectively guarantees the safety of small children, prevents the danger that falling appears in children, concerning the school-ager, is supported on chest with railing during reading and writing, can effectively keep correct sitting posture.But this chair lift also is not suitable for the children in 3-10 of the present invention year, and complex structure, and cost is higher, and its balustrade design is smaller for the children's in 5-10 year protective action, but brings the difficult new problem of taking a seat to them.
Summary of the invention
