(5) specific embodiment

Consult Fig. 1,2, swing seat support 10 of the present utility model be by two between left and right every suspension apparatus 11 with can before and after the mode that swings be erected on the supporting seat 12, described swing seat support 10 comprises: frame 2, one first armrest unit 3, one second armrest unit 3 ', a table 4, can before and after pivot pendulum ground one first chair back 5, one second chair back 5 ' on the present frame 2 are installed, and between left and right every one first adjusting device 6, one second adjusting device 6 '.

This frame 2 comprises: at interval a front stall bar 21 of front and back, a back seat bar 22, front and back to the several connecting rods 23 that are engaged on 21,22 on two bars, be overlapped on two seat cushions 24 of 21,22 on two forward and backward bars, and between left and right every two first pivot sheets 25, the two second pivot sheets 25 ' of solid welding on back seat bar 22.

This armrest unit 3,3 ' is on the fixing present frame 2 in compartment of terrain, the left and right sides, because two armrest unit 3,3 ' structure are identical, below first armrest unit 3 only is described.First armrest unit 3 of the present utility model comprises: handrail 32 in every the outer armrest 31 and between left and right, wherein this outer armrest 31 has two front and back straight bar section 311 at interval, and one level be engaged on hand between two straight bar sections, 311 tops by section 312, and interior handrail 32 also has two straight bar sections 321 and on the other hand by section 322.4 of this tables are to be overlapped on 32 on two armrest unit 3,3 ' interior handrail.

This chair back 5,5 ' be with can before and after the mode of pivot pendulum install on the present frame 2 because two chair back 5,5 ' structure are identical, below only explain with first chair back 5.First chair back 5 of the present utility model comprises: two between left and right every chair back side lever 51, several joining rod 52 that is engaged on 51 of two chair back side levers, and first pivot 53 that passes chair back side lever 51 bottoms and the corresponding first pivot sheet 25.And this second chair back 5 ' also comprises two chair back side levers 51, several joining rod 52 that is engaged on 51 of two chair back side levers, and two second pivots 53 '.

Cooperate Fig. 3, and this adjusting device 6,6 ' function are to be used for keeping the chair back 5,5 ' lying angle,, below only explain with first adjusting device 6 in left side among Fig. 2 because each adjusting device 6,6 ' structure are all identical.First adjusting device 6 of the present utility model comprises: two groups between left and right every adjustment unit 60, an and trace 66, wherein each adjustment unit 60 all has: one is combined in the hand of side handrail 31 (or 32) regularly by the clip plate 61 of below, section 312 (or 322), a clamping piece that extends back to front 62, a hinged arm 63, and a positioning rod 64.This clip plate 61 have one define one the sealing clamping groove 65 cell wall 611, described clamping groove 65 comprises: a level is positioned at the logical portion 651 of slippage of top, and communicating with the logical portion 651 of this slippage and one first location division 652, one second location division 653 of arranged askew from front to back, and one the 3rd location division 654.And have on this cell wall 611 one toward first location division 652 outstanding preceding prominent stopper 612, toward the outstanding processus aboralis stopper 613 in second location divisions 653, and three lead-in chamfered 614 that are positioned at each location division 652,653,654 leading edge.

Clamping piece 62 of the present utility model has a pivot pendulum that is positioned at the place ahead and holds 621, and one be positioned at the rear and wear with the root point of first chair back, 5 combinations for axle hinged arm 63 and hold 622, the hand that has a upset 90 degree at pivot pendulum end 621 front ends is pulled portion 623, and this backstay 64 is to be located on the pivot pendulum end 621, and be positioned at hand and pull portion 623 rears, described backstay 64 laterally penetrates the clamping groove 65 of clip plate 61, and can move in each location division 652,653,654 and 651 in the logical portion of slippage.And this trace 66 is 622 at root point ends that are combined in the clamping piece 62 of two adjustment units 60 regularly, so that this clamping piece 62 of interlock.

When the utility model first chair back 5 is positioned at a preceding dependence position shown in Figure 1, the backstay 64 of this first adjusting device 6 is across in first location division 652 of clamping groove 65, be subjected to the left-right symmetry traction of both sides clamping piece 62, this first chair back 5 is to be location shape and slightly past hypsokinesis pendulum.

Consult Fig. 3,4, when first chair back 5 of the present utility model will be transformed into the middle dependence position of Fig. 4 by the preceding dependence position of Fig. 1, be to be that root first chair back 5 of naming a person for a particular job pushes forward with both sides first pivot 53, the clamping piece 62 of this first adjusting device 6 moves forward thereupon when pushing, be subjected to the guiding of first location division, 652 the place ahead lead-in chamfered 614, pass the backstay 64 top displacement forward gradually of clamping groove 65, because this backstay 64 is mounted on the pivot pendulum end 621 of clamping piece 62, therefore this action can cause the logical portion 651 of the slippage that moves corresponding clamping groove 65 on the backstay 64, that is to say, be transformed into the state of Fig. 3 by the preceding dependence position of Fig. 1.The hand of hand steered then clamping piece 62 is pulled portion 623, allow backstay 64 maintain the position of the logical portion 651 of corresponding slippage, and make first chair back 5 toward backward shift, when the opening on 653 tops, backstay 64 corresponding second location divisions, as long as loosen this clamping piece 62, aforementioned clamping piece 62 and backstay 64 just can move down, and as shown in Figure 4 the state clip in second location division 653 of clamping groove 65.

Cooperate Fig. 5, identical reason, when first chair back 5 of the present utility model will be transformed into the dependence position, a back of Fig. 5 by the middle dependence position of Fig. 4, the mode of its operation is identical with the action specification of leading portion, just backstay 64 moves on to the logical portion 651 of slippage earlier, the back together again pendulum of two clamping pieces 62 of first chair back 5 and interlock repeats no more then.Because first chair back 5 of the present utility model is positioned at the back when leaning on the position, incline toward the back lower places angle of pendulum of whole first chair back 5 is many greater than preceding dependence position, and therefore at normal dependence state, this first chair back 5 can be firm is positioned at this dependence position, back.Identical reason, when first chair back 5 will be transformed into the preceding dependence position of Fig. 1 by the back dependence position of Fig. 5, push away this first chair back 5 before needing only, this backstay 64 just can be by each lead-in chamfered 614 step by step toward anterior displacement, that is to say, first chair back 5 leans on when leaning on the position before the position is transformed into again in the middle of being transformed into by dependence position, back, and the pivot that does not need to pull two clamping pieces 62 is put end 621.Though above-mentioned explanation is to explain with first chair back 5, the adjustment mode of the utility model second chair back 5 ' is identical with first chair back 5, no longer explanation.

Certainly, when adjusting first chair back, 5 user modes, the user draws two clamping pieces 62 that are positioned at first armrest unit, 3 both sides before also can be directly, that is to say that the explanation of the utility model aforementioned operation is a kind of feasible pattern, during enforcement not as limit.And the quantity of location divisions can increase according to need in this clamping groove 65, in the design also not with exceeding that embodiment was disclosed.

By above explanation as can be known, the overall space kenel of this swing seat support 10 of the utility model is not only innovated, this design also can make swing seat support 10 can multistage ground adjust the chair back 5,5 ' lying angle, so as to improving the comfortableness that swing seat support 10 uses, therefore the utility model really is that a structure is novel, and the swing seat support with preferable comfort.
