Problems solved by technology

The locking device / switching mechanism of the above two schemes has the following deficiencies: ① switching is primitive and troublesome, and does not meet the requirements of convenient, reliable and high-grade switching mechanism; Stepless adjustment of seat height; only static use of two positions of sitting and lying can be realized; ③ cannot realize the switching operation of sitting and lying on the chair; ④ cannot be applied to the sofa; ⑤ its parts are basically self-made parts, high cost and time-consuming

example 1

[0037] The main operations and actions of instance one.

[0038] They can only achieve static use of sitting and lying down.

[0039]When sitting, the sitting and lying seat is locked by the controllable / locking gas spring assembly 1-2. When the reclining seat is to be gradually switched from the sitting position to the lying position, the following linkage occurs due to the kinematic characteristics of the parallelogram frame K-P. A person sits on seat A-2, operates control button I 6-1-2, controllable / locking gas spring assembly 1-2 loses the locking force, but still has a constant force. Back to seat back A-1, overcome the constant force of controllable / locking gas spring assembly 1-2 and the elastic force of compression spring 1-7-1-2 on pneumatic push rod 2-1-2, seat back A- 1 Gradually lean back, and the center of gravity of the human body moves backward: ① During the process of gradually switching from the sitting position to the lying position, the pressure on the co...

example 2

[0040] The main operations and actions of the second instance.

[0041] It enables static use of sitting and lying and dynamic use of movement.

[0042] 1) Static use of sitting and lying down.

[0043] When sitting, the sitting and lying seat is locked by the electric push rod assembly 2-2. When the sitting-reclining seat is to be gradually switched from the sitting position to the lying position, the following continuous motion occurs due to the kinematic properties of the parallelogram frame K-P. When a person sits on a sitting and lying seat, operates the control button II 5-2-2, the power of the electric push rod 2-2-2 makes the seat back C-1 gradually tilt backward, and the center of gravity of the human body also moves backward: ① Sitting and lying seat The support point of the original sub-support component C-3 moves back synchronously with the rearward movement of the center of gravity of the human body, ensuring the stability of the process and the lying position, ...

Abstract

The invention relates to a sitting-lying switching mechanism of a sitting-lying sitting device. The sitting-lying switching mechanism is composed of a frame part and a switching locking device, the frame part is a parallelogram frame, and the two ends of the switching locking device are movably connected with two connectors, and connected with suitable positions of the parallelogram frame through the two connectors. A control button is operated, pulling force and locking force of the locking device are changed, the position of the sitting-lying sitting device is switched, and stepless adjustment of sitting, half-sitting and lying positions is achieved. According to the sitting-lying switching mechanism, the movement characteristics of the parallelogram mechanism and the switching locking device are perfectly combined, static using of sitting and lying and dynamic using of movement of the sitting-lying sitting device are achieved, operation of meridian, vital energy and blood, and blood of a whole body is accelerated, and the better condition is created for reliving 'a variety of hazards brought by excessive sitting', ' a variety of benefits of afternoon nap' and body building and health maintenance; and mass consumption of the sitting-lying sitting device can be better facilitated.

Description

technical field [0001] The present invention relates to the technical field of furniture, in particular to a sitting and lying switching mechanism of a sitting and lying seat. Background technique [0002] The seat referred to in this article is a general term for chairs and sofas. [0003] There has been a social consensus on the two common everyday problems of "the harms of prolonged sitting" and the "benefits of naps". Patent No. ZL201721517914.0 "retractable sitting and lying office, study chair" and patent No. ZL201820336205.0 "a telescopic sitting and lying two-use chair" two technical solutions, try to achieve dual use of sitting and lying The popular consumption of chairs will change the limitations of the existing reclining chairs, create conditions for efforts to reduce the "all kinds of harms caused by prolonged sitting", and create conditions for office workers and students to bring "all kinds of benefits of naps". Both of these two technical solutions use the ...
