Description

Lie prone and sit dual-purpose chair

Technical field

The utility model belongs to the furniture technical field, exactly is a kind of dual-purpose chair of lying prone, sit.

Background technology

Current chairs, no matter pattern and material are how, its design is with a kind of with the theory of manufacturing, promptly for people's behind by designing.It is very comfortable that the people is sitting on the chair back inclination meeting, but work as man-hour, and the chair back of chair has just lost effect.As child learn, do the homework, centre of body weight such as operating computer leans forward, like this time one long can be tired, especially child's head and the weight ratio of trunk be greater than the adult, so fatiguability more causes eye and books hypotelorism, development is gone down will be near-sighted.

Summary of the invention

The purpose of this utility model is in order to overcome the problem that existing chair exists, to provide a kind of and lie prone, sit dual-purpose chair, can not only sitting, and can lie prone, the needs when especially satisfying child's learning fatigue.

The purpose of this utility model is to realize with following technical proposal: this is lain prone and sits dual-purpose chair, and it mainly is made up of the spine of chair, the chair back, head rest and connection chair, the chair back, head rest.Its special feature is that spine is made up of the vertical part and the sweep of lower end, and head rest is movably connected in the upper end of spine, and the chair back is fixedly connected on the spine middle part, and chair is connected with the sweep of spine.Angle between described head rest and the spine can be regulated between 90 ° to 180 °; Keep certain distance between the vertical part of horizontal of chair and spine.

The utility model compared with prior art has following advantage: it not only possesses the effect of existing chair, but also has the function that existing chair can't be realized.For example, the mediocrity is sitting on the chair, is leaning against the chair back, and when seat fatigue of a specified duration was wanted to lean forward, existing chair can't be realized the posture that it leans forward, and have to lie prone on desk by both hands, so can cause myopia to reach healthy unfavorable.And the utility model can be avoided so unfavorable generation.As long as chair is turned 180 °, be sitting at this moment that the shirtfront leans against on the chair back on the chair during use, 90 ° of head rest upsets are held up head on head rest, and quite people's bench over is lain prone on chair.Can regulate fatigue conditions at any time when child learns, allow he (she) a comfortable study attitude is arranged, can also guarantee child when study eyes with desk certain appropriate distance is arranged, be difficult for near-sighted.

The specific embodiment

Figure specifically explains unitary construction of the present utility model and operation principle in conjunction with bowing:

Shown in Fig. 1～3, the described dual-purpose chair of seat of lying prone is made up of the spine 4 of chair 1, the chair back 2, head rest 3 and connection chair, the chair back, head rest.Wherein main vertical part 4-1 and the sweep 4-2 of spine constitutes, and vertically the epimere in the part is adjustable sections 4-3.Chair is fixedly connected on sweep one end of spine, and the chair back is fixedly connected on the vertically stage casing of part of spine, and head rest is movably connected in the vertically end of the rise sections of part of spine.Wide before chair is the same with common chair, the back is narrow, is surrounded by sponge and lining 1-2 above the chair frame 1-1, and is bound by screw; Consult shown in Figure 2ly, the chair back is welded on the spine by chair back rack 2-1, wraps up sponge and lining 2-2 thereon and constitutes; Head rest is by carriage 3-1, is enclosed with sponge and lining 3-2 thereon and constitutes.Head rest and spine are for flexibly connecting, it can link together by a fixed axis 3-3 and spine, wherein the stage casing of fixed axis 3-3 is welded on the spine upper end, carriage two frames are movably connected in the two ends of a 3-3 respectively, midpoint at the upper side frame of carriage is provided with a hole, flexibly connect head rest location supporting rod 3-4 on the hole, head rest is located by the head rest location supporting rod.The connected mode of head rest and spine is a lot, for example also can adopt the connected mode of universal joint; The way that the vertical part 4-1 of spine adopts with its adjustable sections 4-3 and is threaded, pin 4-4 is fixing constitutes, and this is very general connected mode; Also can adopt two joint grafting up and down, the junction is by the fastening type of attachment of swivel nut, and the bar linkage structure form that can regulate length in daily life is a lot, so be easy to realize.

Its operation principle: when sitting usually, at first regulate the height of head rest, 4-4 fixes with pin, and is the same with normal chair, leans against on the chair back, and head rest can study on head rest, operating computer or written document etc.But study or working time one are of a specified duration, just feel position fatigues, uncomfortable such as head, the back of the body, at this moment chair are turned 180 ° of recoils on chair, and two legs straddle the both sides of spine crooked position.Because the coupling part of spine and chair is a bending section, so the human body bottom there is not obstruction, it is very comfortable to be seated, at this moment the upper body chest that turns forward leans against on the chair back, head rest location supporting rod 3-4 extracts the hole from the spine shown in Fig. 2, head rest is rotated 90 ° forward, then the buckle end of head rest location supporting rod is inserted below the spine in the hole.At this moment head can hold in the palm and hold up the study that works on head rest.When if head or arm think that a left side or right holder are held up, adjust spine to raise sections be 90 ° as long as reverse.
