Description

Improved structure of chair frame

Technical Field

The utility model relates to an improved structure of a chair frame, in particular to an improvement of a seat frame.

Background

Chairs are ubiquitous in our lives, work, and leisure. The most common chair in daily life consists of a chair back, a seat and chair legs. Slowly, various industries have made chairs of different kinds, functions, shapes for their respective industrial purposes.

The existing chairs are not only simply sitting, but also are provided with deck chairs for the comfort of leaning and sitting. In addition, the combination of the chair back and the chair body is designed for comfort and individual needs, and a plurality of chairs can be used for sitting and lying down for rest.

After the person ages, all body functions can be degenerated, bones become pure, the response is slow, and all functions are coordinated. Especially after age 75, many elderly people are struggling with too low or too short seats, whether they sit down or stand up. Many old people sit down, squat to a certain procedure and then sit on a chair with a fierce force, and need to stand up or hold up with someone when getting up.

The height of the seats of most of the existing chairs is fixed, and the height of the chairs like office chairs can be manually adjusted. However, when the height of the seat can be manually adjusted, the feet need a certain program to exert force, and the adjustment mode is only simple vertical adjustment, the seat only moves up and down, and the seat cannot be adjusted by rotating the seat up and down around a point.

The other end of the lifting telescopic rod is movably connected with the lifting main frame.

By adopting the structure, when the telescopic rod extends, the lifting main frame of the seat frame is slowly lifted towards the oblique upper side, so that the herringbone support is forced to be pressed downwards, the herringbone support drives the front end of the side plate of the mounting frame to be pressed downwards and simultaneously drives the front end of the side plate of the seat frame to be pressed downwards, and thus the front end of the whole seat frame device is pressed downwards and the rear end is lifted upwards; the reverse is right when the telescopic rod is lifted and contracted. Therefore, the old people can do the stretching movement of the chair frame when wanting to do so, and then do the contracting movement after the hip stands lightly against the seat. The same is true when standing up. When a person wants to have a rest after making a steady state, the telescopic rod of the seat frame is started to work, and the seat mounting frame slowly moves backwards when the rod is extended, so that the side plate of the seat frame is pushed forwards and simultaneously drives the seat back mounting support to enable the seat back to lie down flatly. The reverse happens when the rod is retracted.
