Description

Sitting station working chair
Technical Field
The invention relates to the technical field of swivel chairs and office chairs, in particular to a working chair with freely-convertible sitting and standing states.
Background
Generally, a chair includes a seat pan, a back plate coupled to one side of the seat pan, and support legs coupled to an underside of the seat pan. The chair also includes armrests coupled to the seat plate or back plate to support the arms of the user and a headrest coupled to the back plate to support the head of the user.
For most chairs, especially office chairs, only the sitting function is provided; from a physiological aspect, a person stands for a long time and is overloaded in legs, so that the person is easy to feel tired; people who sit for a long time feel uncomfortable or tired, and various diseases such as hypomnesis, headache and dizziness, lumbar vertebra and cervical vertebra and the like are caused by insufficient cerebral blood supply, weight of the whole body pressing on the bottom end of the vertebra and the like, so that the health is not good. Sedentary adverse physical conditions have been studied and reported for a long time in which one person wishes to sit and for a long time to stand.
Among sedentary people, it seems that office white collar and students who learn in school sit for the longest time, and they sit for work or learning almost all the day over the hour, and it is difficult to adjust the posture, and not only is the person easily tired, but also the body is easily affected. The solution to this problem is preferably to allow alternating "sitting" and "standing" of the person.
There are chairs with sitting function in the prior art, for example, the application number of the Shanghai motor college proposed by the 2014 3 month 21 day is: "CN201410106815.8", invention name: the invention relates to a Chinese patent of a chair capable of sitting and standing, which comprises the following using method:
(1) When the sitting mode is wanted, the left turning plate 10 and the right turning plate 11 can be adjusted to be in a horizontal state through the first supporting rod 1201, the first sliding pin 1401, the first fastening bolt 1301, the second supporting rod 1202, the second sliding pin 1402 and the second fastening bolt 1302, so that the left turning plate 10 and the right turning plate 11 are made into a seat, a person can sit on the seat and lean on the backrest 6 to pedal on the foot rest 15, and the movable armrest 8 can be put down for use.
(2) When the "standing posture" is desired, the left turning plate 10 and the right turning plate 11 can be vertically put down through the first support rod 1201, the first sliding pin 1401, the first fastening bolt 1301, the second support rod 1202, the second sliding pin 1402 and the second fastening bolt 1302, so that a person can lean against the backrest 6 "straddling" the cross beam 9 to be in a standing state, and the movable armrest 8 can be put down for standing and use.
(3) When the form of single-side standing is adopted, one of the left turning plate 10 and the right turning plate 11 can be independently put down, and the other is kept in a horizontal state. Specifically, the left turning plate 10 or the right turning plate 11 can be vertically put down through the first support rod 1201, the first sliding pin 1401 and the first fastening bolt 1301 or the second support rod 1202, the second sliding pin 1402 and the second fastening bolt 1302, so that a person can sit on one half of the backrest 6, the other half of the foot can straighten and directly step on the ground, and the movable armrest 8 can be put down for use.
The chair realizes the conversion between sitting stations through the cooperation of the left turning plate 10, the right turning plate 11 and the cross beam 9, but the structure is not suitable for office chairs with armrests and lifting air bars, and the application condition has limitation.
US7350863 discloses a height-adjustable working chair, the column 3 being made up of three parts 4,5,6, providing two levels of adjustability to the seat height; the seat is divided into two parts 7,8 in such a way that the rear part 7 is fixed and always kept in a substantially horizontal position, while the front part 8 is hinged with respect to the rear part; and the front portion 8 is fixed in an articulated manner to the column 3 by means of a rod 9, which rod 9 is fixed in an articulated manner to the front portion.
The working chair is characterized in that the rear part 7 is lifted through the lifting of the posts 5 and 6, and the front part 8 is in an inclined state, so that the rear part 7 supports a human body, can adapt to people with different heights, and can be used by people with short stature in standing postures.
Disclosure of Invention
The invention overcomes the defects in the prior art, and provides the device which has simpler and more flexible structure and can be adjusted by a user according to the needs of the user: or sitting or standing, thereby providing convenience for alternating between sitting and standing postures; more importantly, the invention can be used comfortably for the same person in both standing and sitting positions.
The technical scheme of the invention is realized as follows:
a sitting station work chair comprising:
a base assembly;
a seat supported on the base assembly;
the seat is rotatably connected with the base assembly through a pivot, and comprises a first supporting part and a second supporting part formed at the rear end of the first supporting part, and the first supporting part is horizontally arranged at the upper end of the base assembly in a horizontal lying state for supporting the buttocks and legs of a human body; the seat is pivoted forward until the first support is in an upright position, thereby raising the second support and supporting the legs of the person.
Preferably, the chair further comprises a back frame or back support movable between upright and reclined operating positions, the second support portion being located forwardly of the lower end of the back frame or back support in the reclined position of the chair. When the chair seat is lying down, the second supporting part is hidden in front of the lower end of the chair back support or the chair back frame, and no extra occupying position is caused.
In order to allow the seat to be used in a stationary and normal manner in the corresponding condition, it is preferable to include a stop device for locking the seat in a lying or standing condition.
Preferably, the limiting device comprises a base and an operating handle, wherein a sliding groove and a sliding plate in sliding fit with the sliding groove are arranged in the base, the sliding plate is provided with a clamping hook, and the operating handle controls the sliding plate to move so that the clamping hook is locked or unlocked in a clamping mode with the corresponding position of the base component.
