Description
Technical field
The invention belongs to field of furniture, relate in particular to a kind of automatic lifting chair.
Background technology
Chair has very strong practicality, in each room, all can occur, its major function is convenient to people's rest exactly, so its comfort level is to weigh the main standard of a chair quality.
Chair lift is a kind of novel chair, it mainly consists of seat board, backrest, support, support rocking arm, lifting-positioning device and chair pin, between support and chair pin, by support rocking arm, carry out correspondence hinged, support rocking arm be take and is hinged on jointed shaft on chair pin and rotates up and down as the center of circle, when shaking support rocking arm, drive support to carry out lifting, realize the lifting of seat board; In addition, between support and chair pin, be also provided with lifting-positioning device, individual chair has more polytropy to the utilization in space many people chair, the sofa large compared with area, individual chair is because of the difference of its circle back of the body moulding, in the utilization in space, also there is different function and usage, if the proper individual character that reflects owner of using, improperly can try to be clever only to end up with a blunder; High back of the body formula individual chair, is applicable to using at home, can pass out leisure, house-atmosphere easily; Streamline moulding, color contrast are strong, the seat of the strong visual sense of beauty of tool, very applicable bachelor or operating room; The leisure chaise longue that personal style is strong, chaise longue, rocking chair, be applicable to being seated in one jiao, space or balcony, as the switching station of mood.
The lowering or hoisting gear that chair lift is on the market used is divided into 3 classes: oil pressure, mechanical type and vapour-pressure type, the most frequently used to chair lift in the majority with air pressure, in Pneumatic type lifting chair, there is individual cylinder, piston air-leg in cylinder moves up and down and arranges chair lifting, regular producer all adopts nitrogen to fill, concentration is generally more than 99%, pressure is one or two atmospheric pressure left and right, this regular chair lift, but the chair lift of this vapour-pressure type may be blasted: nitrogen gas purity is not enough, in hot environment or friction too frequently in situation, can cause temperature cylinder to rise sharply, it is large that pressure becomes, blast, cylinder container wall is firm not or material is poor, blasts, seal poorly sealed closely, cause gas to burst out, blast, and pressure liftable chair is in use blasted and can be caused very large injury to user.
Evening on April 20th, 2007, Zhoushan, Zhejiang Province Dinghai District, the chair of Mrs's Lou seat is blasted, and seat is worn by fried, the trousers that Mrs Lou wears have been exploded a large hole, and a large amount of fragments such as duroplasts, wood chip, sponge, cloth, sealing ring collapse in Mrs's Lou body and reach ten centimeters.
In evening on November 26th, 2007, the pressure liftable chair that development zone, the Yantai Wu old Mr. of 68 years old sits is blasted, and buttocks, shank, rectum anal tube and small intestine are badly wounded.
26Wan， in March, 2008 Ganzhou city, the computer chair in a woods house of Mr. is blasted suddenly, Mr.'s Lin back, on hand etc. locates injuredly, and the little iron rod of about 15 centimeter length is blown up on ceiling.
On January 14th, 2009, Jiangzhou, Shandong 14 years old juvenile little just (assumed name) online of being in alone, when the lifting of adjustable pressure chair, blasts suddenly, and push rod, in the little rigid body of buttocks jacking, injures many blood vessels, rear because of excessive blood loss, death that all rescue measures proved ineffectual.Doctor claimed at that time, and the accident of this turning chair has occurred 3 within short January.
In sum, although conventional chair lift has facilitated people's routine work and life at present, but also exist potential risks, once chair lift is blasted, the injury that user is caused is very serious, even entail dangers to is to life, is therefore necessary to provide a kind of security higher and use convenient chair lift.
