Embodiment 1

[0041] Example 1: Reference Figure 1~Figure 7 , a new type of sofa structure, used on a sofa with an adjustable support structure, which can be switched between sitting, lying and even semi-lying positions. The transmission structure is reasonable and reliable, and makes the occupant in a semi-recumbent position The feet are strongly supported, and it can also be retracted inside the seat, which is convenient to use;

[0042] The backrest 1 and the seat cushion 2 are hinged, and the two sides of the seat cushion 2 are provided with armrests 3, and the curtain in front of the seat cushion 2 is also provided with a window 2-1 for the self-adjusting structure c to extend and retract;

[0043] A linkage a is arranged inside the armrest, and a self-adjusting structure c is arranged under the seat cushion 2;

[0044] Linkage piece a is set in the frame at the two armrests of the seat, and the inner side of the frame is fixed with an inner frame made of steel pipe through screws. O...

Embodiment 2

[0055] Example 2: Reference Figure 1~Figure 7 , a new type of sofa structure, the difference from Example 1 is: the inner contour of the chute a-2.1 is provided with a lubricating inner sleeve a-2.11, and the lubricating inner sleeve a-2.11 is made of an elastic material base layer and set The lubricating layer is formed on the elastic material base layer, and the sliding bar a-2.2 is in contact with the lubricating layer. The sliding direction within a-2.1 advances, and the distance between the lubricating layers inside the chute a-2.1 gradually decreases;

[0056] The base layer of elastic material is made of elastic rubber, and the lubricating layer is made of polytetrafluoroethylene.

[0057] The lubricating inner sleeve a-2.11 can lubricate the sliding rod a-2.2 and the chute a-2.1 when they move relative to each other, making the mediation movement smooth and convenient without stagnation; at the same time, the lubricating layer on the inside of the chute a-2.1 When t...

Abstract

The invention discloses a novel sofa structure, and belongs to the technical field of adjustable seats. The structure is hinged by a backrest and a seat cushion, wherein two sides of the seat cushionare provided with armrests. A linkage member and a gas spring are arrange in that armrest; When the linkage moves relative to the frame with the hinge end as the center, the gas spring is elongated orshortened with the hinge joint with the middle part of the linkage as the force receiving point. A self-adjusting structure is arranged below the seat cushion. The self-adjusting structure is composed of a telescopic part with one end fixedly connected to the lower part of the seat cushion and a self-adjusting foot cushion with the other end hinged to the telescopic part. The novel sofa structureis used on the sofa with adjustable support structure, and can be switched between various forms of sitting posture, lying posture and semi-lying posture, the transmission structure is reasonable andreliable, and the foot of the occupant in the semi-lying posture is strongly supported, and the sofa can be retracted from the inside of the seat and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of adjustable seats, in particular to a novel sofa structure. Background technique [0002] Seats are tools that are convenient for users to ride. Sofas and chairs can be called seats. In order to make people ride more comfortably, people will consider providing foot support and backrest support for passengers in a semi-recumbent posture to make them more comfortable. for the ride. [0003] The backrest of the traditional sofa usually cannot be adjusted greatly, so it is often impossible to provide an effective and comfortable rest posture when the user needs a lunch break, and the foot support is often a fixed structure, which cannot be retracted into the seat, which is inconvenient to use and cannot be adjusted according to the occupant The body shape adjusts the height of the foot support, and now a new type of sofa that can retract the inside of the seat and adjust the supporting structure is needed. ...
