Description
Art
The invention belongs to chair art, particularly a kind ofly lean against protruding adjustable seat.
Background technology
The seat of the seat around existing seat, especially Domestic dining table and beach, Condom, leans against and only has a kind of shape mostly separately, or to recurve or slightly-inclined is straight or slightly convex arch.The people that present people suffer from lumbar vertebra disease is more, and particularly, the elderly, what have is sitting on chair, always likes with a pad group pad leaning against at seat.Like this, they can feel comfortable.But present most of seat back does not have outwardly convex part, or not protruding, can not meet part population to the requirement leaning against degree of convexity, bring uncomfortable sensation to them.
Summary of the invention
The object of this invention is to provide and a kind ofly lean against the adjustable seat of bossing, be both applicable to suffering from lumbar vertebra disease and liked leaning against protruding high crowd, be applicable to again not suffering from lumbar vertebra disease and most young crowd use.
The present invention is achieved in that and a kind ofly leans against protruding adjustable seat, primarily of seat cushion, seat board, foot rest, backrest, by curtain, fagging, fagging axle, gear, tumbler gear, tooth bar, handle composition, the needs according to people can change seat outwardly convex degree with handle.Here with tradition old-fashioned by seat cushion, seat board, lean against, seat that foot rest forms describes.On leaning against, arranging a width by curtain, is wear Lian Duogen by the rope of band elastic to make by block by curtain.By curtain top be arranged on the upper, lower horizontal frame of backrest below.By being provided with fagging after curtain.Fagging one side is straight flange from top to bottom.Fagging straight flange is mounted with fagging axle.Fagging axle upper and lower end is provided with axle sleeve.The upper and lower axle sleeve of fagging axle is arranged on the upper, lower horizontal frame of backrest respectively.That limit facing to fagging axle on fagging is a curve.Curve becomes the smooth form of an outwardly convex from top to bottom.Fagging and fagging axle have Second Mate, are arranged on side by side on the upper and lower frame of backrest, have certain distance each other.A gear is installed below fagging axle separately.Pinion rotation makes fagging axle rotate.The gear side of a fagging axle there is also mounted a tumbler gear.Support installing, below backrest, support has been installed the fairlead of tooth bar.Be provided with tooth bar in fairlead, the tumbler gear that tooth bar matches with gear and another root fagging shaft gear of a fagging axle is meshed.Tooth bar one end is flexibly connected with screw mandrel.The nut of screw mandrel is fixed on the support below backrest.Screw mandrel outer end is connected with handle.Swinging handle, screw mandrel pulls tooth bar to move horizontally, and rack drives gear and tumbler gear rotate, and two pairs of faggings are all rotated towards the direction parallel with by curtain.Reverse swinging handle, screw mandrel tooth pushing bar oppositely moves horizontally, and driven gear and tumbler gear rotate backward, and Second Mate's fagging is all rotated towards the direction vertical with by curtain.Leaning against protruding shape is that the angle of being rotated by fagging axle is determined.Detailed process is: when not needing to lean against projection, swinging handle, and tooth bar forward is moved, and driven gear and tumbler gear rotate, and drives fagging to rotate towards the direction parallel with by curtain, makes to set level by curtain; When needs lean against projection, reverse swinging handle, makes tooth bar oppositely movement, and driven gear and tumbler gear, fagging axle rotate backward, and fagging is rotated towards the direction vertical with by curtain, makes by curtain outwardly convex.Namely outwardly convex is leaned against by curtain outwardly convex.
The invention has the advantages that: lean against the degree that can regulate outwardly convex.When fagging is with when leaning against vertical, the highest by curtain outwardly convex, when fagging is parallel with by curtain, just losing the support of outwardly convex by curtain, do not have outwardly convex by curtain, is be closed flat state.A seat, can be applicable to the needs that needs lean against protruding crowd, can be applicable to again the needs that not needs lean against protruding crowd.

In accompanying drawing, by curtain 1, seat cushion 2, seat board 3, foot rest 4, backrest 5, fagging 6, fagging axle 7, handle 8, threaded block 9, screw mandrel 10, fairlead 11, gear 12, axle sleeve 13, tooth bar 14, tumbler gear 15, support 16.
Detailed description of the invention
In Fig. 1, it is the seat leaning against outwardly convex state.Seat is formed by by curtain 1, seat cushion 2, seat board 3, foot rest 4, backrest 5.Backrest 5 is the support frames leaned against.Worn Lian Duogen made by block by the rope of band elastic by curtain 1.By curtain 1 the top and be separately fixed at bottom on the upper, lower horizontal frame of backrest 5.During by curtain 1 outwardly convex, elastic slightly elongates, and respectively slightly becomes large by gap between block.By after curtain, fagging 6 is installed, is straight flange on the right of fagging 6, straight flange is mounted with fagging axle 7.Fagging 6 left side is arch outwardly from top to bottom, in order to prop up the shape being supported by curtain and protruding.Handle 8 is arranged on backrest 5 side frame lower end.
In Fig. 2, be fagging and transmission associated structural component structure.Backrest 5 is installed two groups of faggings 6 and fagging axle 7, often has suitable distance between group.In figure, two groups of faggings are all turn to the position parallel with leaning on curtain.Fagging axle 7 upper and lower end is arranged in respective axle sleeve 13.The upper and lower axle sleeve 13 of fagging axle is arranged on the upper, lower horizontal frame of backrest respectively.A gear 12 is installed below two fagging axles 7 separately.Gear 12 rotates and fagging axle 7 is rotated.Gear 12 installation site below that root fagging axle of the right exceeds the height of a gear than the gear position below the fagging axle of the left side.That gear of the right is meshed with a tumbler gear 15.Tumbler gear 15 has two gears high like that, and that gear lower end of lower end and the left side is concordant.Support 16 is provided with outside backrest 5 lower transverse frame.The pivot pin at tumbler gear center is arranged in axle sleeve 13 fixing on backrest lower transverse frame.The gear of tumbler gear and two fagging axles is arranged side by side.Tooth bar 14 level is installed, and engages with the gear on the fagging axle of the left side and tumbler gear.Tooth bar 14 upper surface, a little less than the gear lower end on the fagging axle of the right, is not interfered mutually.Two fairleads 11 are fixed on support 16, and tooth bar is arranged in fairlead 11, in order to support tooth bar and guiding tooth bar.Threaded block 9 is fixed on support 16.Screw mandrel 10 is through threaded block 9, and right-hand member is flexibly connected with tooth bar, screw mandrel is rotated in threaded block and left and right mobile time can draw, tooth pushing bar is left and right moves horizontally.Screw mandrel is mounted with handle 8 in threaded block 9 outer end.
In Fig. 3, be lean against not outwardly convex situation.When rotating clockwise handle 8, screw mandrel 10 rotation move right simultaneously, tooth pushing bar moves to right, on the right of rack drives fagging axle cog inhour rotate, fagging is rotated towards with paper parallel direction.Rack drives tumbler gear counter-clockwise direction is rotated simultaneously, and tumbler gear drives the right fagging axle to cog and rotates clockwise.As a result, the right fagging also rotates towards with paper parallel direction simultaneously.Finally, two groups of faggings all turn to parallel with paper, then lose outside support by curtain, become the straightened condition of withdrawal.
Rotate the handle in Fig. 2 when counter-clockwise direction, then two groups of faggings all rotate towards the direction vertical with by curtain, when two pieces of faggings turn to vertical with by curtain, by curtain outwardly convex to extreme higher position, as Fig. 1.
Swinging handle, adjustable fagging overturns different angles, makes by curtain projection in various degree.
