When user's shank during at rounding state, lock spacing rivet Y and contact with confined planes 1, the spacing rivet J of shank contacts with confined planes 2 41 and has played a locking position-limiting action.Driving arm fixture 181 and driving arm tumbler 182 have been formed driving arm 18 after being rotationally connected by the 23 rotating shaft 23, and driving arm fixture 181 is by fixing point 22,24 are fixedly connected on chair mounted plate 16 top (adopting bolting to connect usually), handle 20 is installed in 25 places, drag-line hole on the driving arm tumbler 182 by drag-line line 21, when pulling handle 20, driving driving arm tumbler 182 by drag-line line 21 rotates around the 23 rotating shaft 23, therefore driving arm tumbler 182 acts on the lock bracket 1 by drive surface 26, lock bracket 1 rotates (the 22 rotating shaft W adopts one usually and drives square tube) around the 22 rotating shaft W, therefore lock bracket 1 passes to shank locking connector 2 by the first rotating shaft A again and produces a motion forward, and shank locking connector 2 is put leg connector 3 after making by the second rotating shaft B and is produced relative rotation around the 11 rotating shaft L, after put leg connector 3 and drive the outside by the 3rd rotating shaft C again and put 5 motions of leg connector, and the outside is put and is put leg connector 4 before leg connector 5 makes by the 5th rotating shaft E and produce relative rotation around the tenth rotating shaft K, before put leg connector 4 and drive inside by the 4th rotating shaft D and put 6 motions of leg connector, yet outside leg connector 5 and inner the 6th rotating shaft F that moves through that puts leg connector 6 of putting, the 7th rotating shaft G drives foot-rest bracket 7 and rotates, simultaneously by the 9th rotating shaft I, put leg support 8 in the middle of the 8th rotating shaft H drives and rotate that (centre is put leg support 8 and is optional part, do not influence the stretching routine of whole shank, the purpose of putting leg support 8 in the middle of being provided with is to make shank launch to increase when the back user puts leg the strong point, comfortable more), rely on the pulling force of spring 19 simultaneously, therefore make whole activity put leg and produce a stretching routine, when the spacing rivet J of shank contacts with confined planes 3 42, produce a position-limiting action, activity is put leg and is reached the full extension state, put in the process of leg stretching, extension in activity, after put leg connector 3 and drive shank by the second rotating shaft B and drive connector 12 and travel forward, shank drives connector 12 makes back rotating connector 14 rotate around the 20 rotating shaft U by the 21 rotating shaft V again, in this process, backrest mounting bracket 15, the 15 rotating shaft P between chair mounted plate 16 and the preceding rising connector 17, the 16 rotating shaft Q and the 17 rotating shaft R do not produce and relatively rotate relatively, so backrest mounting bracket 15, chair mounted plate 16 and preceding rising connector 17 are put in the process that leg stretches as a whole in activity, back rotating connector 14 drives backrest mounting bracket 15 by the 18 rotating shaft S again and produces certain rotatablely moving around the 12 rotating shaft M, and backrest realizes that part tilts.
As Fig. 2, Fig. 3, when on backrest mounting bracket 15, applying a power F1 (generally promptly relying on user's self gravity) as the figure direction, backrest mounting bracket 15 rotates around the 18 rotating shaft S, rising connector 17 produced rotatablely moving of making progress around the 12 rotating shaft M before backrest mounting bracket 15 made by the 16 rotating shaft Q again, preceding rising connector 17 drives chair mounted plate 16 front portions by the 15 rotating shaft P again and moves upward, simultaneously, backrest mounting bracket 15 also drives chair mounted plate 16 rear portions by the 17 rotating shaft R and moves upward, therefore realized the whole upwards motion of lifting in seat, simultaneously, backrest mounting bracket 15 drives part 13 motions that are linked in sequence by the 19 rotating shaft T again, when confined planes 6 131 contacts with the 21 rotating shaft V, produce a position-limiting action, backrest is in the state of toppling over fully.
About the utility model embodiment comprises when forming a complete cover seat machinery extending apparatus two of symmetry and be installed in fixed support between them (except that driving arm 18 mutually, driving arm 18 can be installed in the left side, also can be installed in the right side), fixed support adopts steel pipe, iron pipe usually, bolt is adopted in being connected between the utility model embodiment and the fixed support usually, can form the complete Disassembling sofa machinery extending apparatus of a cover.
Rotating shaft among the utility model embodiment adopt usually bolt, pin, rivet or rivet add spring shim etc. similarly mode realize being rotationally connected.Because overall structure is fairly simple, in motion process, the movement locus of shank driving connector 12, the part 13 that is linked in sequence, back rotating connector 14 is relatively large from the distance of bottom linkage rod 9, therefore the length of rotating connector 10 and back fixed connecting piece 11 reduces the seat height of whole brandreth before can shortening, usually it is high 0～20 millimeter to reduce seat, the actual seat of present embodiment high with compared in the past about decline 20mm.The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought to fall into protection domain of the present utility model.
