Description

The closestool chair chair back leans on the adjusting device of height

Technical field

The chair back that the utility model relates to a kind of closestool chair has the function that can tune to proper height, allows the back of different height occupant, can obtain the comfortable dependence meeting ergonomic designs.

Background technology

Known closestool chair structure, usually the front and back between side frames are all comprised, be horizontally set with the forward and backward crossbearer be linked to therebetween, and closet is equiped with between forward and backward crossbearer, and the upper end of side frames forms armrest part and two lower ends form foot tube parts, simultaneously the rear side of side frames is made again to install a chair back rack again, when allowing occupant on closestool chair, make its back can rest on this chair back rack, figure for comfortable dependence and support.

But, the chair back rack both sides of known closestool chair, general is all directly be fixed in side frames by rivet or screw, namely chair back rack is cannot carry out changing or adjustment on position after fixing again, cause the back of the occupant of different height, be all rest on the chair back rack of sustained height, the height that the excessive height causing shorter people to lean on or higher people lean on is too low, and then allows occupant not feel well and cannot obtain suitable and good support and dependence.

Therefore, above-mentioned known closestool chair takes the comfort level of dependence, and the occupant being not enough to deal with different height uses, and also lacks adjustable mechanism simultaneously.

Utility model content

Edge is, in order to improve the above-mentioned known closestool chair chair back, do not adjust the problem of the mechanism of height, the utility model provides the two ends making door shape chair back rack, to be interspersed on rear side of side frames and set to wear in pipe portion, and the outboard shafts that order wears pipe portion is to being interval with multiple locating hole, be equiped with at the two ends end terminal of chair back rack can elastic telescopic and the snap-on that can be fastened in the locating hole of arbitrary relative position simultaneously, and then chair back rack must be made can be adjusted to the At The Height of suitable occupant's back-resting.

The utility model solves the technical scheme that its technical problem adopts: comprise in shaped door and its upper end becomes armrest part, two ends are formed between the front and back of the relative side frames in interval of foot tube part, if by front, rear crossbearer is linked to therebetween, and front, the span of rear crossbearer establishes a closet, and the foot tube part making side frames respectively hold wears the telescopic leg pipe of a scalable location, the two ends of a chair back rack in shaped door are established to be installed in the rear side place of side frames more again, and making on rear side of side frames slightly top opposite position respectively be provided with, axially spaced-apart on it is provided with multiple locating hole wears pipe portion, this approach end end, chair back rack two ends opposite position is respectively equiped with tool elastic telescopic, and snap-on position that both sides wear the arbitrary relative position in pipe portion determining in hole can be buckled into.

In such scheme, this wears pipe portion and comprises a front tube portion and be set on rear side of side frame on foot tube part to which is provided with the rear pipe portion of the plurality of locating hole in parallel and formed, and make the inner side of front tube portion foreign side establish a conjugation tube portion linked with one end of this rear crossbearer, and on foot tube part, be fixed with the upper and lower block set of firmly this front tube portion admittedly of pivot therebetween.

The beneficial effects of the utility model are, by the above-mentioned snap-on wearing multiple locating hole and the chair back rack two ends place installing that pipe portion is axially arranged, chair back rack is allowed to be able to wearing the adjustment and location of pipe portion carrying out upper and lower diverse location, and then make chair back rack can adjust suitable back-resting height according to the occupant of different height, what occupant can be leaned on comforts and more accords with the design of ergonomics.
