Abstract
The invention relates to a sight protection chair with a sitting posture correction function. The sight protection chair includes a chair frame, a pressing chair seat, shoulder pressing claws and a linkage unit, wherein the pressing chair seat does pressing action on a chair leg supporting frame when a person sits on the pressing chair seat and downwardly applies pressing acting force to the pressing chair seat; at the moment, the pressing acting force is synchronously transferred to the shoulder pressing claws by means of the linkage unit, so that the shoulder pressing claws synchronously do pressing action on a back rest; thus, the shoulders of a human body are pressed and clamped by the shoulder pressing claws; the pressing acting force and pulling force towards the back rest are simultaneously applied to the shoulders of the human body by means of the shoulder pressing claws; when the person moves away from the pressing chair seat and the pressing acting force is eliminated, the pressing chair seat is lifted on the chair leg supporting frame; at the moment, the shoulder pressing claws are driven by means of the linkage unit to be synchronously lifted on the back rest; and thus, the pressing chair seat and the shoulder pressing claws are reset, and the shoulder pressing claws are moved away from the shoulders of the human body.
Description
Technical field
The present invention relates to a kind of seat, refer to a kind of seat of the protection eye eyesight in order to correct human body read-write posture especially.
Background technology
The mankind can recognize the color of more than 7,500,000 kinds by eyes, so eyes serve very important effect for people's perception external world.Seen this function of object by eyes, be called as vision.Vision mainly feels the comprehensive consciousness such as light and shade, color, sound, distance, size.The effect of the camera lens of the crystal in the eyes of the mankind, pupil, amphiblestroid effect and camera, aperture, film is the same.Camera lens is crystalline, and aperture is pupil, and film is retina.Pupil regulate enter light in eyes number, light overlaps on crystalline, forms focus, regulates crystal thickness by galley proof body, then is refracted on retina by crystal and forms image.So the light on arrival retina is through certain process, is just transferred to brain by optic nerve and produces vision.
Just because of the unique effect of eyes so eyes have extremely important effect in the sense organ organ of human body, correct read-write posture can ensure the health of eye eyesight, neck should be kept above the waist upright when people utilize eyes to read and write, head is obtained and supports, two shoulders naturally droop, upper arm presses close to health, elbow is bending in 90 degree, operation keyboard or slide-mouse, makes wrist keep flat-hand position as far as possible, palm center line and forearm center line, should keep a straight line.Lower part of the body waist is straight and upright, and knee natural torsion is 90 degree, and maintains the double-legged sitting posture landed.
In order to ensure that above-mentioned correct read-write posture must select to meet the tables and chairs of ergonomic designs, use special computer chair, follow above being sitting at " three right angles ": under computer desk, knee forms first right angle, thigh and back are second right angles, and arm forms the 3rd right angle at elbow joint.Shoulder blade leans against on the chair back, and both shoulders put down, and chin is neck beyond this point.Two computer screen central authorities at eye level, seat preferably has the supportive chair back and handrail, and can adjust height.
But due to children or teen-age self-disciplining also poor, the read-write posture that maintenance that often can not be conscious when children or teenager are sitting in and seat is read and write time is correct, if things go on like this eyes will inevitably be damaged, and then have influence on the eyesight of eyes, and the seat of the function that corrects faulty sitting posture also not having a kind of effectiveness comparison desirable now occurs, and this is the major defect for conventional art.
Summary of the invention
The invention provides and a kind ofly there is protecting of the function that corrects faulty sitting posture look chair, the posture of human body read-write can be corrected by its structural design thus reach the effect of protection eye eyesight, and this is main purpose of the present invention.
The technical solution adopted in the present invention is: a kind of have protecting of the function that corrects faulty sitting posture and look chair, it comprises chair frame, presses down seat support, presses shoulder pawl and linkage unit, wherein, this chair frame comprises chair leg carriage and backrest, and this backrest lower end is fixedly connected on this chair leg carriage.
This overall chair frame is connected to form by this chair leg carriage and this backrest, this chair frame has the structure of general seat, wherein, this chair leg carriage can support the main by weight of human body, the back of human body can rest on this backrest, thus reaches and play whole human body by this chair leg carriage and this back rest supports.
This presses down seat support and is movably arranged on this chair leg carriage, this presses down seat support and up and down reciprocatingly press down the action with lifting on this chair leg carriage, this pressure shoulder pawl pivot is connected on the top of this backrest, this pressure shoulder pawl up and down reciprocatingly presses down the action with lifting on this backrest, this linkage unit is connected to this and presses down seat support and this pressure is takeed between pawl, when human body be sitting in this to press down on seat support and to this press down seat support apply pressing force downwards time, this presses down seat support and make pressing action on this chair leg carriage, this moment, by this linkage unit, this pressing force is synchronously passed on this pressure shoulder pawl, this pressure shoulder pawl synchronously makes pressing action on this backrest.
This pressure shoulder pawl just can press down the shoulder blocking human body like this, pressing force and the pulling force to this backrest direction are applied to the shoulder of this human body by this pressure shoulder pawl simultaneously, thus ensure that the back-resting of human body is on this backrest, reach and make human body be sitting in the effect protected depending on chair remaining correct read-write posture of the present invention.
And when human body from this press down seat support remove this pressing force eliminate time, this presses down seat support and do lifting action on this chair leg carriage, this moment, drive this pressure to take on pawl by this linkage unit and synchronously do lifting action on this backrest, thus make this press down seat support and the reset of this pressure shoulder pawl, this pressure shoulder pawl is removed from the shoulder of human body like this, thus ensures that human body can leave from of the present invention protecting depending on chair.
This chair leg carriage is fixedly installed cover on each this spring stack of some spring stacks and is provided with spring, this presses down on seat support bottom surface and is provided with some sleeves, this spring stack is plugged in this sleeve, make this press down seat support by this spring and can up and down reciprocatingly press down the action with lifting on this chair leg carriage, further, this chair leg carriage also offers locating hole, this presses down on seat support bottom surface and is connected with locating dowel, this locating dowel activity is plugged in this locating hole, this locating dowel is arranged with spring, the horizontal displacement that this presses down seat support is limited by this locating hole and this locating dowel, make this press down can not to occur between seat support and this chair leg carriage the phenomenon misplaced.
This linkage unit comprises trace and interlock stay cord, wherein, this trace is slidably arranged on this backrest, this trace lower end is hooked on this and presses down on seat support, this interlock stay cord one end is connected to the top of this trace, and other one end of this interlock stay cord and this pressure are takeed on pawl and be connected, this is pressed down seat support and this pressure by this trace and this interlock stay cord like this and take on pawl and link together and make both be synchronized with the movement.
