Description

Band keyboard support computer rocking chair

Technical field

The present invention relates to a kind of Computer chairs, and are a kind of computer rocking chairs with keyboard support.

Background technique

Rocking chair shake is moved for body joints and internal organ, with comfortable relieving fatigue, is promoted QI-blood circulation, is reached guarantor Strong purpose.In the prior art, the computer rocking chair with keyboard support shakes axle center and is each provided at below seat.When chair is swung back When, body gravity integrally deviates backward, and the rear bigger gravity eccentricity in the elevation angle is bigger, and the corrective force for needing to give is bigger, therefore this Structure is big to power, and waving angle is small.When manually giving power, the shake amplitude of this rocking chair is generally no greater than 20 degree.It is so small Angle, parts of body drop is small, and comfort level is poor, and it is even more impossible to easily stay in any angle in the absence of external forces. Even if that makees the rocking chair of camber with ground contact portion, the angle of shake is not more than 30 degree, otherwise only by lower limb into The adjusting of the row arm of force cannot achieve gravitational equilibrium, and this rocking chair is scroll forward and backward, and occupied space is big, is not suitable for office and uses Chair.At present with the electric rocking chair of keyboard support, although shaking than existing artificial rocking chair, amplitude is big, and randomness is poor, shakes amplitude (angle Degree) it is difficult to adjust, and structure is complicated, at high cost, and vibration and noise can bring body and mind not relax to people when operation, therefore long-term difficult To be received by the majority of consumers.The especially existing electric rocking chair with keyboard support is technically broken through without essence, Wu Fa great Amplitude continuously and smoothly shakes, and rigid mechanical is uncomfortable, lacks practicability.

Summary of the invention

It is at low cost the object of the present invention is to provide a kind of structure is simple, do not shake and noise, can significantly it is continuous arbitrarily It shakes, and speed and amplitude (angle) are arbitrarily variable, and can be in the convenient stop of any angle, it can office-recreational be dual-purpose, work is protected The strong computer rocking chair to develop simultaneously.It is adopted the technical scheme that, the connection that chair shakes part and fixed part is set as axis and axis Cooperation is held, two side axles are arranged on the outside of armrests close to upper limb position, and two sides axial connecting line is higher than occupant's buttocks, is not higher than Umbilical region, axial connecting line the upright projection of seat surface occupy seat surface rear up-front 2/5ths to seat surface at, occupant's body weight The heart matches with bilateral axis axial connecting line (shaking the axial line of part), makes to adapt to different fat or thin and height occupants With, in addition to chair model makes differentiation, also can be used different-thickness cushion and backing cushion cooperation, make body center of gravity regardless of It is that can be generally in rocking chair in the horizontal direction or in vertical direction and shake shaft core position, without departing from leg adjustment Limit of power.This structure, more than axle center and axle center body gravity below is close, and traffic direction is opposite.When chair after When facing upward, moved beneath, axle center way up side's movement below can not only remain that gravity is flat to the body above axle center backwards Weighing apparatus, and moving horizontally apart from short, parts of body are displaced that drop is big, and chair occupies little space, and office is suitble to use.When making When with desktop computer, display can be placed on the desk in front of chair, not only reduce the radiation to body, can more be forced and be taken a seat The eyes of person follow rocking chair constantly movable, protect eyesight with movable eye.Therefore, be protection vertebra, the backrest of rocking chair relative to Seat surface vertical line, the rear elevation angle can be larger than conventional chair, and are equipped with the neck brace of lordosis on backrest top, bent according to the cervical vertebra of people Degree, lordosis distance is between 60 to 100 millimeters.Keyboard support is made of keyboard drawer and pallet, and pallet is used for holding keyboard, mouse Or laptop.Pallet is lain against on keyboard drawer, when occupant will rest or disseat, can not operate it is other any In the case where component, arbitrarily by pallet from keyboard drawer upper end from.To prevent pallet from sliding in shake, can keyboard drawer with Guide pile and location hole are set between pallet, groove can also be set on keyboard drawer.To prevent laptop or keyboard, mouse It slides, the surrounding of pallet can set flange, and add computer fixer.In the fixed part of chair, to keep structure simple, only use A piece positioning beam lain across between the base frames of two sides limits and shakes start bit and layback stop bit, and is equipped with buffer on crossbeam, To reach comfortable locating effect.The material of buffer can be spring, can also be the resilient cushion or damping sleeve of soft material.Of the invention Maximum benefit is that structure is simple, and using comfortable convenient, manually small to power, waving angle is big, and body is traversing apart from small, and displacement is fallen Poor big, parts of body can be during the shake of big drop using self gravity potential energy mutually cosily extruding and kneading, favorably In QI-blood circulation, relieving fatigue.And it can substantially mitigate upper body to the pressure of vertebra, to protect vertebra.This rocking chair shakes maximum shake Angle is not less than 50 degree, is not only adapted to work and is used, and when layback, which stops angle, is greater than 45 degree, can make chaise longue use.

Detailed description of the invention

Fig. 1 is overall package front view of the present invention；Fig. 2 is overall package side view；Fig. 3 is to shake fragmentary elevational view；Fig. 4 It is to shake partial side elevation view；Fig. 5 is fixed part front view；Fig. 6 is fixed part side view.In figure, 1 shakes part, and 2 is solid Determine part, 3 backrests, 4 handrails, 5 axis, 6 seat surfaces, 7 supports, 8 keyboard drawers, 9 pallets, 10 rears, 11 leading edges, 12 pedestals Frame, 13 positioning beams, 14 buffers, 15 bearings, 16 castors.

Specific embodiment

In conjunction with attached drawing: shaking part 1 and fixed part 2 forms present invention band keyboard support computer rocking chair, shake part 1 by solid Surely backrest 3, bilateral handrail 4, bilateral axis 5, seat surface 6, item support 7, bilateral keyboard drawer 8 and the pallet 9 to link together forms, Gu Part 2 is determined by the base frames 12, positioning beam 13, buffer 14, bearing 15 and rotatable 16 groups of the castor that are fixed together At with bilateral axis 5 and the mating connection of bearing 15 between shake part 1 and fixed part 2, shake part 1 surrounds 5 axle center of bilateral axis Line rotation.Bilateral axis 5, which is respectively perpendicular, to be fixedly connected on the outside of two side handrails, 4 upper limb, and axle center is not less than occupant's buttocks, Not higher than umbilical region, the axial connecting line of bilateral axis 5 is in the upright projection position of seat surface 6, in seat rear 10 to seat leading edge 11 At 2/5ths, vertical line of the backrest 3 relative to seat surface 6, the rear elevation angle is generally no greater than 20 degree, and (i.e. the angle of seat surface and backrest is little In 110 degree).Its top is equipped with forwardly convex item support 7, and lordosis distance is not less than 60 millimeters.Keyboard support is by two sides keyboard drawer 8 It is formed with pallet 9, before keyboard drawer 8 is fixedly connected on two side handrails 4,9 both ends of pallet are lain against on two sides keyboard drawer 8, can In the case where not operating other any parts, arbitrarily directly hold from keyboard drawer 9.Positioning beam 13 shakes part 1 for limiting Shake start bit and layback stop bit, shake part 1 maximum waving angle can be more than 50 degree.Positioning beam 13 is equipped with buffer 14, material can use spring, it is also possible to soft material resilient cushion or sleeve.
