Description

Sit upright integral type office chair

Technical Field

The utility model relates to a technical field of office chair especially relates to a sit upright integral type office chair.

Background

The invention patent related to the office chair is searched in the Chinese knowledge network, and the number of the invention patent is 506.

Among them, there is concern about sedentary injuries. Such as an office chair (CN108991A, 2018-12-14) for preventing sedentary sitting, it is inconvenient to work by moving the chair down slowly, and thus people are encouraged to stand up and move about. This technique does not provide the limitation of a healthy posture for a standing office posture.

In addition, there is also interest in standing office chairs. For example, in an ergonomic standing office chair (CN108420216A.2018-08-21), adjustable supports are used for the neck, waist and buttocks, but this technique only addresses the posture requirement of standing office and does not address the requirement of sitting office.

In structural aspect, although there are few inventions of the conversion seat of sitting and standing, such as a standing office chair (CN106175232A), a method for supporting the seat surface to rotate forward by 90 ° to erect the seat by adjusting the length of the rear hydraulic column of the seat is described. The conversion from the supporting sitting posture to the supporting standing posture is realized. Patents (CN107136789A), (CN204245504U) and (CN106617802A) both use a slide and a lock structure, but the solution is complicated to operate and cannot be implemented with one hand and one step, and patent (CN106175202A) uses a relatively heavy quadrilateral telescopic frame, which has many structures and large volume although being fast to deform, and is not suitable for the modern simple office environment and the light weight requirement of users.

In summary, the prior art has been concerned with addressing either the prevention and amelioration of discomfort caused by sedentary persons or the need for a chair while standing in the office. There is a lack of breakthrough for a support structure for an office chair that converts from a sitting position to a standing position. In the existing technology of sitting and standing multifunctional seats, most structural components are thick, heavy and complex, and the operation is responsible, so that the multifunctional seats are difficult to adapt to the modern and simple office space environment.
