AI Technical Summary

Technical Problem

The support legs of existing folding recliners are prone to accidental rotation during use, affecting stability, and they tend to swing freely when folded for storage, making storage and transportation inconvenient.

Method used

Design a support leg linkage mechanism for a folding recliner. Through a transmission link, a four-bar linkage is formed with the seat frame, backrest, and support legs to realize the automatic unfolding and folding of the support legs. The angle between the support legs and the backrest is adjusted by a telescopic rod and a locking device. The stability is improved by combining the four-bar linkage and auxiliary links.

Benefits of technology

It achieves stable unfolding and folding of the support legs, avoiding accidental rotation during use, facilitating storage and transportation, and the adjustable angle adapts to different ground surfaces, improving stability and comfort during use.

Abstract

The utility model belongs to the technical field of reclining chairs, and particularly relates to a supporting leg linkage folding and supporting mechanism of a folding reclining chair, which comprises a bed body and a supporting frame used for supporting the bed body, the bed body comprises a seat frame and a backrest which can be folded relatively, the supporting frame is arranged on the seat frame, and supporting legs are rotatably arranged on the backrest. Transmission connecting rods are arranged between the supporting legs and the seat frame and are rotationally connected with the supporting legs and the seat frame respectively; the backrest and the seat frame are controlled to be relatively unfolded, and the transmission connecting rod can drive the supporting legs and the backrest to be relatively unfolded, so that the supporting legs can support the backrest; the backrest and the seat frame are controlled to be folded relatively, and the transmission connecting rods can drive the supporting legs and the backrest to be folded relatively. The transmission connecting rod is a telescopic rod piece; or a plurality of mounting positions connected with the supporting legs and the seat frame are arranged on the transmission connecting rod; the utility model aims to provide the supporting leg linkage folding and supporting mechanism of the folding deck chair, which is stable in structure and convenient to store and transport.
