Description
Technical Field
The utility model belongs to the technical field of furniture technique and specifically relates to a sit and lie and switch frame of sitting and lying thing to sit on.
Background
The seat referred to herein is a generic term for chairs and sofas.
On day 7, 15, the State Council issued "State Council's opinion on the implementation of healthy Chinese actions". The opinion further emphasizes that the concept and service mode of promoting health and hygiene work are changed from treating diseases to people's health, …. Social consensus has been reached for the two common daily problems of "all kinds of hazards from sedentary life" and "all kinds of benefits from afternoon nap". We try to solve the two problems in daily life and change the life style in this aspect, so as to change the treatment to people health. The technical scheme includes three technical schemes of 'a telescopic sitting and lying dual-purpose office and learning chair' with the patent number ZL201721517914.0, 'a telescopic sitting and lying dual-purpose chair' with the patent number ZL201820336205.0 and 'a sitting and lying switching mechanism of a sitting and lying seat' with the application number 201910637925.X (hereinafter, the three patent technologies are simply referred to as 'three technical schemes'), and the technical scheme aims to realize popular consumption of the sitting and lying dual-purpose chair, change the use limitation of the existing sitting and lying chair, create conditions for reducing 'various hazards brought by long-time sitting', and create conditions for bringing various benefits of afternoon nap to groups such as office staff, students and the like. The main body mechanisms of the seat frame in the three technical schemes are all parallelogram mechanisms, and the movement characteristics of the parallelogram mechanisms are fully utilized to realize the switching of the sitting and lying of the seat under the coordination of the locking device. When the gravity center of a human body gradually moves backwards in the process of switching from the sitting position to the lying position, the auxiliary supporting piece moves backwards along with the gravity center of the human body, so that the contact area between the seat and the ground is increased, the seat is prevented from being turned backwards, and the lying position is stable. In the process of switching from lying to sitting, the seat back and forth rotates forwards, the auxiliary supporting piece contracts forwards, and the auxiliary supporting piece is guaranteed not to be in the way. The seat is convenient and reliable to switch between sitting and lying, stepless to adjust and upscale. When lying down, the feet rest on the ground.
The design has a consensus, the same product function and effect can be achieved by using a structure which is as simple as possible, the design is a good design, and the product is a good product. The technical scheme is expected to try to reform the main mechanism of the three technical schemes through another simpler structure/mechanism by applying a reverse thinking method, so that the same product functions and effects of the three technical schemes are achieved, even the three technical schemes exceed the main mechanism in some aspects and are complementary with the main mechanism, and the sitting and lying furniture is applicable to a wider range.
