Description

Rocking chair with two-stage angle adjustment

Technical Field

The invention relates to a rocking chair capable of adjusting angles in two stages, and belongs to the technical field of household articles.

Background

The prior rocking chair has two types. A chair seat and a backrest are two independent parts, the chair seat is fixed, the bottom of the backrest is connected with the chair seat, the backrest can rotate by taking the joint as an axis, the position of the backrest relative to the chair seat is adjusted to form different angles, and different requirements of people for sitting or lying are met. However, the back of the person is integral, and when the person lies on the rocking chair with the chair surface and the backrest independent and at an angle, a gap is formed between the back and the rocking chair. The rocking chair can not provide support for the back, and can feel uncomfortable even affect the health after long-time lying or sitting. Another rocking chair consists of a frame and an integral chair seat which is made of soft mesh or a plurality of parallel wooden boards, and the back of the chair seat is connected by reinforcing ribs to provide integral support from the head to the knees. A plurality of clamping grooves are arranged below the rocking chair armrest and are clamped on the limiting blocks; when the angle is adjusted, the armrest is lifted, the armrest is moved back and forth to be adjusted to a required position, the clamping groove is aligned to the limiting block, the armrest is put down, the limiting block is clamped into the clamping groove, and the inclination of the chair surface can be adjusted. However, because the seat surface is made of an integral soft material, when a person sits on the rocking chair, the seat surface from the head to the hip part can be pulled straight and tight due to the gravity, and the back of the person is bent physiologically, so that the rocking chair can feel uncomfortable when sitting or lying although the supporting degree of the rocking chair is improved compared with that of the prior rocking chair; another disadvantage is that the inclination angle is adjusted by matching the clamping groove with the limiting block, so that the requirement of most people cannot be met by limited stage selection.
