Abstract

The invention relates to a dual-purpose revolving chair capable of changing the sitting posture, which comprises a seat cushion, a backrest, a backrest frame, a titling shaft, a transverse bracket, a shaft sleeve frame, a bracket, a suspension rod, a base shaft, a transverse lever and a fulcrum shaft. The backrest frame rotatably moves upwards along the fulcrum shaft, when moving to the position where the backrest basically and vertically stands on the seat cushion, the bracket rotates to cause the backrest frame to be supported so as to fix the position of the backrest, then the seat cushion rotates horizontally, and the revolving chair is positioned in the general sitting posture at the moment, so that people can have a rest; and after the bracket rotates for 90 degrees, the backrest frame falls down, the backrest downwardly moves for 60 degrees, then the seat cushion rotates to slope along the backrest direction to provide an angle, and the revolving chair is positioned in a special sitting posture at the moment, so that the demand that people lean forward for some work when sitting is met.

Description

Can change the dual-purpose revolving chair of sitting posture

Affiliated technical field

The present invention relates to a kind of swivel chair, specifically relate to a kind of dual-purpose revolving chair that changes sitting posture.

Background technology

At present, existing chair class comprises that its significant feature of swivel chair and function are to sit down for people's intersection point, for being sat down, the people feels comfortable, so cushion is arranged to the almost horizontal shape, a backrest also is equipped with at the back allows the people rely on, yet this chair, when sitting down, the people when doing some work, but experiences less than this comfort sense, this is because do some work for example when doing electronic assemblies, people's angle that need turn forward broadens the scope of work, therefore, have to allow artificially the chair angle that turns forward satisfy such sitting posture, cushion is turned forward, and backrest has also lost the effect that relies on because of turning forward, so existing chair class comprises that swivel chair can not satisfy the needs of the special sitting posture of people under certain workplace.

Summary of the invention

The purpose of this invention is to provide a kind of dual-purpose revolving chair that changes sitting posture, with the needs of the special sitting posture under the general sitting posture that satisfies the people and certain workplace.

Solve the technical scheme that its technical problem takes and be for reaching above-mentioned purpose the present invention: by a cushion, a backrest, a back rest, an inclined shaft, a transverse bracket, an axle sleeve frame, a carriage, a suspension rod, a datum axle, a whippletree and a fulcrum shaft are formed the dual-purpose revolving chair that can change sitting posture, an inclined shaft is equipped with in described cushion below, in the oblique cover in the inclined shaft insertion axle sleeve frame, inclined shaft can drive cushion and freely rotate along tiltedly overlapping, axle sleeve in the described axle sleeve frame below is enclosed within the datum axle, can freely rotate between axle sleeve and the datum axle, described transverse bracket and axle sleeve frame are assembled into one, described back rest is the U type, two garden pipes about being divided into after the place's bending of U type, two effective fulcrum shafts in garden of described back rest one end are connected with an end of transverse bracket, described back rest can rotate up and down along fulcrum shaft, two garden pipes of described back rest are connected with screw with backrest in the crooked nearly 90 degree backs of cushion edge, a cross bar is contained in described back rest knee, and two garden pipes in the back rest are welded together, described suspension rod passes carriage and is connected with the axle sleeve frame, can freely rotate between described carriage and the suspension rod, the working method that changes the dual-purpose revolving chair of sitting posture of the present invention is such: when desiring to make swivel chair be in general sitting posture, rotating back rest moves up along fulcrum shaft, when moving on to the backrest near vertical when standing on the cushion, rotating bracket makes it hold back rest with this fixing position of back, rotating cushion again makes it horizontal, at this moment, two pin land, buttocks is sitting on the cushion of level, lean against on backrest, simultaneously cushion and backrest are rotated along datum axle, thereby the people can be had a rest fully, when desiring to make swivel chair be in special sitting posture, rotating bracket 90 degree, back rest is fallen, till whippletree props up datum axle, be that backrest has moved down about 60 degree, rotating cushion again makes it to angle of backrest direction inclination, at this moment, buttocks is sitting on the cushion of inclination, two shanks prop up backrest, and whole health can turn forward, and feel very comfortable equally thereby do some work with this special sitting posture.

A kind of dual-purpose revolving chair that changes sitting posture of the present invention both can have been worked as the leisure seat, can do some work when special sitting posture usefulness again.
