Abstract
The present invention relates to a kind of office health-care chairs for sitting crowd back fatigue.It is uncomfortable that prolonged sitting posture office meeting enables the waist of office crowds generate, and serious person even can generate waist disease, and how to prevent or alleviate this disease generated by sitting seems particularly important.The present invention relates to a kind of office health-care chairs for sitting crowd back fatigue, and mainly the four-bar motion including being equipped between chair leg, movable seat, foot pedal, handrail, backrest and handrail, backrest limits mechanism.Waist twist movement is realized first with sliding seat, the drawing movement then realizing waist anterior flexion and rear stretching respectively using the Motion Bifurcation that four-bar motion limits mechanism, swinging, to meet the characteristics of waist health-care behaviour's substep carries out；Using passive constraint human body waist center of rotation and the center of rotation approximation of office healthcare device are overlapped, final realize completes waist health-care movement by office healthcare device to prevent, alleviate the purpose of the waist disease generated by sitting.
Description
Technical field
The present invention relates to a kind of field of office furniture, and in particular to a kind of office healthcare for sitting crowd back fatigue
Chair.
Background technique
With the increasing of socio-economic development and working strength, office sitting crowd increasingly increases, and pressure is growing day by day,
The time of exercise is shorter and shorter, is easy to cause lumbar fatigue, aches, or even will cause waist disease, existing currently on the market
Health care office chair is broadly divided into two major classes: one type is by fitness equipment in conjunction with office chair, but this health care office chair is big
Most structure is complicated, the bodily form is larger, higher cost, and another kind of structure is simple, the bodily form is smaller, but can only at most carry out waist
Anterior flexion and rear stretching, two kinds of movements of swivel, and do not provide that the center of the center of rotation of office chair and the waist of user is approximate and be overlapped,
Also it is not moved according to the waist health-care movement of complete set authority, so that preferable health-care effect cannot be possessed.
Summary of the invention
(1) the technical issues of solving
Technical purpose of the invention is to provide a kind of office health-care chair for sitting crowd back fatigue, drives and use
Person completes the waist health-care movement of complete set authority.The rotation for increasing by three directions on traditional office chair, utilizes passive constraint

It is fixedly arranged on seat movable plate 4, handrail 7 is fixedly arranged on the vertical bar of chair leg 1, is limited between handrail 7, backrest 9 by four-bar motion
Mechanism 8 links together.
Embodiment 2, referring to Fig. 2, a kind of office health-care chair for sitting crowd back fatigue, in which: four-bar motion
Mechanism 8 is limited by revolute pair 2 10, connecting rod 1, revolute pair 3 12, connecting rod 2 13, connecting rod 3 14, revolute pair 4 15, connecting rod four
16, revolute pair 5 17, connecting rod 5 18, revolute pair 6 19, connecting rod 6 20, revolute pair 7 21, connecting rod 7 22, revolute pair 8 23, company
Bar 8 24, revolute pair 9 25, connecting rod 9 26, revolute pair 10, revolute pair 11, connecting rod 10, revolute pair 12, rotation
Pair 13, revolute pair 14 are constituted, and wherein one end of connecting rod 1 is connected using revolute pair 2 10 with handrail 7, the other end
It is connected simultaneously with one end of connecting rod 2 13, connecting rod 3 14 using revolute pair 3 12, the other end and the connecting rod 4 16 of connecting rod 3 14
Upper end is connected with revolute pair 4 15, and the lower end of connecting rod 4 16 is connected using revolute pair 5 17 with one end of connecting rod 5 18, connecting rod five
18 other end, the other end of connecting rod 2 13, connecting rod 6 20 one end be connected with revolute pair 6 19, the other end benefit of connecting rod 6 20
It is connected with revolute pair 7 21 with one end of connecting rod 7 22, the other end of connecting rod 7 22 utilizes revolute pair 8 23 and the one of connecting rod 8 24
End is connected, and one end of connecting rod 9 26 is connected using revolute pair 9 25 with connecting rod 8 24, and the other end is using revolute pair 11 and even
One end of bar 10 is connected, and is connected using revolute pair 10 with handrail 7, and the other end of connecting rod 10 utilizes revolute pair 12
It is connected with connecting rod 7 22, four-bar motion is finally limited into mechanism 8 and 9 phase of backrest using revolute pair 13, revolute pair 14
Even.Remaining is the same as embodiment 1.
Embodiment 3 please refers to Fig. 3-Fig. 6, and a kind of office health-care chair for sitting crowd back fatigue needs to carry out waist
When portion's swiveling movement, the backrest of office chair 9 is first become into vertical transition, then unclamps corresponding locking mechanism, driving turns
Dynamic pair 1, the foot pedal 6 for enabling seat movable plate 4 and being fixedly arranged on seat movable plate 4 is rotated together, to drive use
The lower part of the body of person rotates, and the upper part of the body of user remains stationary at this time, is finally completed the health care movement of waist twist；It needs
When carrying out waist roll motion, if the retaining mechanism of locking seat movable plate 4 is in releasing orientation, first locked
Tightly, then by the backrest 9 of office chair become vertical transition, then drive revolute pair 10, drive the structures such as connecting rod 7 22, connecting rod 9 26
At quadrangle rotated, thus drive backrest 9 carry out roll motion, at this time by structures such as connecting rod 7 22, connecting rods 9 26
At quadrangle and connecting rod 1 it is no longer coplanar, due to four-bar motion limit mechanism 8 Motion Bifurcation, lead to revolute pair 2 10
It is not able to rotate, is equivalent to and has carried out physics locking, therefore individual retaining mechanism need not be increased, the rotation of revolute pair 10 is locked
It is fixed；When needing to carry out the movement of waist anterior flexion and rear stretching, if the retaining mechanism of locking seat movable plate 4 is in releasing orientation, first by it
Locking, then the backrest 9 of office chair is become into vertical transition, revolute pair 2 10 is then driven, connecting rod 1 is driven to be rotated, from
And backrest 9 is driven to carry out anterior flexion and rear stretching movement, at this time since connecting rod 1 and connecting rod 9 26 are no longer conllinear, lead to revolute pair 10
It is not able to rotate, therefore need not also increase individual retaining mechanism and the rotation of revolute pair 10 is locked.
It should be noted that, in this document, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
