Abstract

The invention discloses a computer rocking chair with a keyboard support. The computer rocking chair consists of a rocking part [1] and a fixed part [2], wherein the two parts are connected in a matched manner through two side shafts [5] and bearings [15]; the two side shafts [5] are respectively fixed in the positions close to the upper edges of the outer sides of armrests [4] on two sides vertically; the connecting line of two axes is higher than the buttock and is not higher than the umbilical region of a person sitting on the chair; the largest rocking angle can be greater than 50 degrees. The computer rocking chair is simple in structure, small in size and large in rocking amplitude, can be positioned in any angle, can effectively relieve fatigue and protect the vertebral column as the rocking speed and the amplitude can be changed randomly, is convenient and comfortable to use, and can be used as a rocking chair in working and a deck chair in leisure time as well.

Description

Band keyboard support computer rocking chair

Technical field

The present invention relates to a kind of Computer chair, and be the computer rocking chair of band keyboard support.

Background technology

Rocking chair shake is for making body joints and internal organ be moved, and with comfortable relieving fatigue, promotes QI-blood circulation, reaches health care object.In the prior art, the computer rocking chair of band keyboard support, its shake axle center is all located at below seat support.When chair is swung back, centre of body weight entirety offsets backward, and the rear elevation angle more large eccentricity is larger, and the corrective force that needs give is larger, and therefore this structure is large to power, and waving angle is little.When manually giving power, the shake amplitude of this rocking chair is generally not more than 20 degree.So little angle, parts of body shake drop little, comfort level is poor, more cannot in the absence of external forces convenient stay in arbitrarily angled.Even if that rocking chair doing camber with ground contact portion, the angle of shake is also no more than 30 degree, otherwise only on the lower the gravity of limb carry out the arm of force and regulate and cannot realize gravitational equilibrium, and this rocking chair is scroll forward and backward, take up room large, be not suitable for office chair.The electric rocking chair of current band keyboard support, although larger, random poor than existing artificial rocking chair shake amplitude, shake amplitude (angle) is difficult to adjustment and complex structure, and cost is high, during operation, vibrations and noise can bring body and mind not relax to people, are therefore difficult to for a long time be accepted by consumers in general.The electric rocking chair of especially existing band keyboard support does not have essence to break through technically, and cannot significantly continuously and smoothly shake, rigid mechanical is uncomfortable, is difficult to do office chair, lacks practicality.

Summary of the invention

The object of this invention is to provide a kind of structure simple, cost is low, not vibrations and noise, can significantly arbitrarily shake continuously, and speed and amplitude are arbitrarily variable, can in arbitrarily angled convenient stop, can dual-purpose, the work of office-recreational to keep healthy the computer rocking chair developed simultaneously.The technical scheme taked is, the connection of chair shake part and standing part is set to axle and bearing fit, it is outer near upper limb position that axle is arranged on chair two side handrail, the axial connecting line of two side shafts is higher than occupant's buttocks, not higher than umbilical region, axial connecting line occupy 2/5ths places of seat surface trailing edge to seat surface leading edge in the upright projection of seat surface, occupant's centre of body weight and twin shaft axle center coincide, in order to adapt to, difference is fat or thin to be used with the occupant of height, except chair model makes differentiation, the cushion of different-thickness and backing cushion also can be adopted to coordinate, health center of gravity is made to be no matter in the horizontal direction or in the vertical direction, all roughly can be in shaft core position, the limit of power of leg adjustment can not be exceeded.This structure, health gravity below more than axle center and axle center is close, traffic direction is contrary, and if chair is when swinging back, the health above axle center moves backwards down, health below axle center is then move upward forward, can not only remain gravitational equilibrium, and move horizontally apart from short, the vertical mobile drop of parts of body is large, chair takes up room little, is applicable to office and uses.When using desktop computer, display is placed on the desk in chair front, not only reduces the electromagnetic radiation to health, the eyes of occupant more can be forced to follow rocking chair constantly movable, with vision protection.For protecting vertebra better when just sitting work, after the backrest of rocking chair, the elevation angle can be larger, and relative to seat surface vertical line, the rear elevation angle is generally set between 15 to 20 degree, and is provided with the neck brace of lordosis on backrest top.According to the cervical curvature of people, before backrest to napex minimum distance more than 60 millimeters, be generally not more than 100 millimeters, not only can protect cervical vertebra better, and be convenient to layback time viewing display screen.The keyboard support of this rocking chair is made up of keyboard drawer and pallet, and pallet is used for holding keyboard, mouse or notebook computer.Pallet lies against on keyboard drawer, when occupant will have a rest or disseat, can when other any parts of inoperation, arbitrarily by pallet from keyboard drawer upper end from, for preventing pallet landing in shake, can guide pile and locating hole being set between keyboard drawer and pallet, also groove can being set on keyboard drawer, make pallet when other any parts of inoperation, arbitrarily by pallet end from tray rack.For preventing notebook computer or keyboard, mouse landing, the surrounding of pallet can establish a grade limit, and adds computer fixer.At the standing part of chair, for making structure simple, only lying across the positioning beam of base frames both sides with one at standing part, limiting shake start bit and layback stop bit, and on crossbeam, being provided with buffer, to reach comfortable locating effect.The material of buffer can use spring, also can use beam or the damping sleeve of soft material.Maximum benefit of the present invention is, structure is simple, it is comfortable convenient to use, artificial power of giving is little, and waving angle is large, and health is traversing apart from little, displacement drop is large, parts of body can utilize the mutual cosily extruding and kneading of self gravitation potential energy in the shake process of large drop, is conducive to QI-blood circulation, relieving fatigue.And significantly can alleviate the pressure of upper body to vertebra, to protect vertebra.The maximum waving angle of this rocking chair is not less than 50 degree.Not only be suitable for the use of work, and when rear elevation setting is greater than 45 degree, chaise longue can be made and use.
