Folding baby chair capable of adjusting back slope

Abstract

The invention discloses a folding baby chair capable of adjusting back slope, comprising a chair seat, a chair back, shank supports, handles arranged on two sides of the chair seat and a lock mechanism for adjusting back slope. One end of the chair seat is pivoted to a lower end of the chair back to form a first pivot pint and the other end is pivoted to the shank supports to form a third pivot pint. One end of the handle is pivoted to the chair back to form a second pivot pint which is located above the first pivot pint, and the other end is pivoted to upper ends of the shank supports to form a fourth pivot pint which is located above the third pivot pint. Accordingly, the baby chair form s a four-bar link mechanism; the chair back can drive the shank supports to rotate and meanwhile to extend or collapse; the lock mechanism can be arranged between any two of the chair seat, the chair back, the shank supports and the handles to lock the two and can operatively release lock between the two. The baby chair is simple and practical, has good stability when tilt to the back side and can optimally collapse in folding.

Description

technical field [0001] The invention relates to a baby article, more particularly to a foldable baby seat with adjustable seat back inclination. Background technique [0002] At present, in the research and development of some baby products, in order to minimize the occupancy rate of space, the design of folding and collapsing is adopted. For example, the baby stroller, when in use, is stretched and opened, and when placed, it is folded and collapsible. On some baby strollers, in order to achieve a further folding effect, the baby seat is also designed to be foldable and foldable, and can be dismantled for easy storage and transportation. For example, a front seat of a baby carriage disclosed on June 24, 2009, the patent number is ZL200820094975.5, the seat part in this patent includes a seat frame tube, a seat fixing tube connected with the seat frame tube, a seat segment seat , the armrest part and the footrest part, there are at least two installation positions on the se...

Problems solved by technology

However, after the inclination adjustment of the backrest part is completed, the angle of the foot part needs to be adjusted additionally. This often requires an adjustment mechanism for the calf part, which virtually increases the cost input, and the independent foot part Design, when the seat is reclined, it will affect the stability of the seat, and when the seat is folded, it will not only affect the convenience of folding, but also affect the degree of folding

In addition, the adjustment mechanism of the backrest part includes seat segment seat, seat fixing tube, seat frame tube pin and escape hole. The adjustment operation mainly uses the seat segment seat to slide on the seat fixing tube and seat frame tube to adjust the angle, and then It is fixed by the seat pin and the avoidance hole, but its structure is relatively complicated and consumable, which is not conducive to production and promotion
