Below in conjunction with accompanying drawing the utility model is described in further detail.

An embodiment of the utility model armchair structure sees also Fig. 1 and Fig. 2, has the structure of the chair back of folding simultaneously, handrail, can be applicable to can adjust on the seat of height.

The utility model is equipped on the runners A, comprises a seat support group 1, a chair back group 2, a pivot pendulum group 3, two handrails 4 and an adjustment group 5.

This runners A is a known structure, for specification for simplicity, only simply describe at this.This runners A comprises a chair pin A1, a plurality of wheel A2 and a lifting group A3, this chair pin A1 lies in the body radiation and is formed with a plurality of gradually vergens pin handles, in each pin handle place installing wheel A2, chair pin A1 can be slided on ground, this lifting group A3 adjusts seat A5 assembly by an elevating lever A4 and and forms, this elevating lever A4 is slidingly installed in adjusting in the through hole of body of chair pin A1, and should adjust seat A5 assembly in the end of elevating lever A4, can control the height of elevating lever A4 by the mechanism that adjusts seat A5, and make the back that the armchair structure of assembly is adjusted height.

This seat support group 1 comprises a seat board 10, one a solid template 11 and a seat cushion 12, a pivot groove 13 is shaped on the plate body of this seat board 10, two groove ends of this pivot groove 13 are all open state, be used to set the pivot pendulum group 3 that to be described after a while, lateral margin at seat board 10 upwards bends extension one tank 101, this tank 101 1 ends are open, the start groove 102 that is shaped of two groove face ora terminalis in its open end, and its bottom land is offered a spacing hole 103.And should be fixedly arranged on this seat board 10 by solid template 11, and one distolaterally be resisted against this tank 101, and again a cushion 12 is equipped on distolateral this tank 101 that is resisted against on the solid template 11.

This chair back group 2 comprises a bearing 20, one a solid template 21 and a back pad 22, groove 23 is held in these bearing 20 shapings one, this holds groove 23 both ends open, stop block 201 in its bottom land shaping one, and the following stop block 202 that its bottom land edge shaping two is corresponding is mutually locked the retaining piece 24 of establishing a scalariform respectively in these stops 201 both sides of performing.Offer two pivot holes 203,204 respectively in the two ends groove face that holds groove 23, pivot hole 203 is to be used for being pivoted with seat group 1 start groove 102, makes bearing 20 can carry out relative pivot pendulum to the seat board 10 of seat group 1.This back pad 22 is to be equipped on this solid template 21, is fixedly arranged on holding in the groove 23 of this bearing 20 with this solid template 21.

This pivot pendulum group 3 comprises a curved rod 30 and two pivot pieces 31, this curved rod 30 is that a body of rod 301 two ends are bent into bending segment 302, with its body of rod 301 spacing pivot grooves 13 that are pivoted on this seat support group 1, this two bending segment 302 is exposed to outer so that two bending segments 302 of this pivot groove 13 and can pivots with the body of rod of curved rod 30 and roll to each side relatively in seat support group 1, two bending segments, 302 ends are overlapped solid this pivot piece 31 respectively, this pivot piece 31 side in addition has pivot part 310, in order to dispose other member that will describe after a while.

This two handrail 4 is hubbed at the pivot hole 204 of bearing 20 both sides of this chair back group 2 respectively, then is pivoted with the pivot part 310 of this pivot pendulum group 3 against, the other end for the user, the bending segment 302 that utilizes curved rod 30 with handrail 4 be supported in the user against predeterminated position on.

This adjustment group 5, be equipped on 2 starts of seat support group 1 and chair back group in order to control chair back group 2 interlock handrails 4, it comprises positioning piece 50, adjust piece 51, adjustment part 52 and elastic component 53, this keeper 50 radial depressions shaping one slot that makes progress 501, one downward slot 502 and the axial limited block 503 that is shaped that protrudes, keeper 50 is with these limited block 503 spacing spacing holes 102 that are arranged in this seat support group 1, and pass the pivot hole 203 of chair back group 2 and be locked in the screw channel 504 of adjustment part 50 with screw, and the bearing 20 of chair back group 2 relatively seat support group 1 carry out spacing pivot pendulum.

The adjustment piece 51 of this adjustment group 5 abuts against the solid template 21 in chair back group 2, the groove 511 of its upper end shaping one two ends opening, and to should groove 511 in adjusting piece 51 rear surfaces two locating convex blocks 512 that are shaped, the last stop block 201 that 512 pairs of this two locating convex blocks should chair back group 2 and be resisted against chair back group 2 hold groove 23 bottom lands.

Adjustment part 52 stage casings of this adjustment group 5 are placed in the groove 511 of this adjustment piece 51, and corresponding respectively following stop block 202 tops, two ends by this chair back group 2, pass the retaining piece 23 of this chair back group 2, and hold along chair back group 2 that groove 23 groove faces bend forward and the trip 521 that is shaped.The trip 521 of this adjustment part 52 colludes the slot 501 of being located at this keeper 50.

Elastic component 53 folding coiled shape two elastic rings 531 of this adjustment group 5 and be sheathed on the locating convex block 512 of this adjustment piece 51, and from the two elastic rings 531 symmetry stretch section 532 that upwards is shaped respectively, the stretch section 532 of this elastic component upwards is resisted against the last stop block 201 of chair back group 2.According to above-mentioned the utility model armchair structure, two bending segments 302 of the curved rod 301 of its pivot goods of furniture for display rather than for use 3 also can be directly and handrail 4 be pivoted and reach its purpose.

Referring to Fig. 2 to Fig. 7, the existing mode of operation of present embodiment is done describes in detail.

Extremely shown in Figure 5 as Fig. 3, when the desire folding has the seat of structure provided by the utility model, the user is upwards compressed the adjustment piece 51 of adjustment group 5 by the rear of seat, the adjustment part 52 that is placed in the groove 511 of adjusting piece 51 is upwards lifted, and by the displacement of retaining piece 24 adjustment parts 52 of chair back group 2, and make simultaneously and be sheathed on the last stop block 201 that the elastic component 53 of adjusting piece 51 is resisted against chair back group 2.

Referring to Fig. 6 and Fig. 7, when the adjustment part 51 of adjustment group 5 moves up, its trip 521 also breaks away from the slot 501 of keeper 53 simultaneously, this moment is to chair back group 2 application of force forward, then chair back group 2 can be by being pivoted of tank 101 of 20 pairs of seat support groups 1 of bearing and dumping forward, the leaning forward of chair back group 2 makes and also it pivoted with its handrail that is pivoted 4 and relative to seat support group 1, and make the pivot pendulum that is pivoted with it organize 3 curved rod 30 to swing forward, cause chair back group 2 repeatedly to lean on, and handrail 4 is moved to seat support group 2 both sides to seat support group 1.And the trip 521 of adjustment group simultaneously 5 corresponds to the slot 502 of adjustment group 5, thereby reaches the purpose of the chair back of folding simultaneously, handrail.

Thereafter, the user decontrols the adjustment piece 51 of adjustment group 5, adjusts piece 51 by elastic component 53 elastic resets, and the trip 521 that makes adjustment group 5 is arranged in the slot 502 of adjustment group 5, and make chair back group 2 be positioned seat support group 1, and make the seat after the folding also have stable structure, conveniently transport or store.

The user is if desire resets chair back group 2, only need chair back group 1 is propped up, allow trip 521 reset of card of adjustment group 5 be located at the slot 501 of keeper 51, can drive handrail 4 resets with pivot pendulum group 3, solve known office chair and can't cause the difficulty of collecting and transporting by folding, in addition, the structure of its chair back of folding simultaneously, handrail allows the operator be easy to the folding operation.
