The specific embodiment:
Referring to figs. 1 through Fig. 4, Folding sofa, comprises the feet that sofa body 1 is identical or symmetrical with both sides; Feet comprises front support rod 2 and the back support rod 3 of activity cross-articulation, and front support rod 2 is higher than back support rod 3, and the raised area forms backrest section 22; Between both sides front support rod 2, by front rail 21, be fixed into one, back support rod 3 is fixed into one by rear transverse rod 31; More particularly, described both sides front support rod 2 and front rail 21 are bent into U-shaped frame by a rod member, and this front rail 21 is in backrest section 22 one end, in order to support backrest jacket; Described two back support rods 3 and rear transverse rod 31 are bent into U-shaped frame by a rod member, and this rear transverse rod 31 lands.
In order to strengthen back and front supporting bar 2,3 in the rigidity intensity at pin joint place, avoid stressed rear supported on both sides pin toward interior receipts, between both sides front support rod 2 and back support rod 3 pin joints, also be hinged with a pass link rod 4, these link rod two ends, pass have bending part 41, two bending parts 41 are close to respectively on both sides front support rod 2, and by rivet clasp or be welded and fixed together.
As Fig. 4 and Fig. 5, described sofa body 1, by flexible fabric machine-shaping, has cushion portion 11, armrest part 12 and the back-rest 13 of disjunctor; Back-rest 13 and armrest part 12 outsides are respectively equipped with backrest jacket 130 and handrail jacket 120, and back-rest 13 is set in backrest section 22 by backrest jacket 130, and by distribution of force to front rail 21; Armrest part 12 is set in back support rod 3 upper ends by handrail jacket 120, between back support rod 3 upper ends and front support rod 2 levels, be provided with reinforcement band 5, in this reinforcement band 5 is wrapped in by handrail jacket 120, Folding sofa is opened and is put in place, this reinforcement band 5, in tensioned state, plays a supportive role to armrest part 12.More particularly, this reinforcement band 5 can be following two kinds of structures:
First reinforcement band 5 is directly made in armrest part 12 inner sides, as Fig. 3, improves the intensity of armrest part 12; It two is that reinforcement band 5 one end are fixed on back support rod 3 upper ends, and the other end is fixed in front support 2, as Fig. 4.Reinforcement band 5 had both played supporting armrests portion 12 effect, was again the constraint of Folding sofa while opening; Because the cushion portion 11 in sofa body 1 relies on armrest part 12 and back-rest 13 lifting, stressedly mainly by handrail jacket 120 and backrest jacket 130, born.
As Fig. 2, Fig. 3 and Fig. 5, the cushion portion 11 of lifting has good soft comfort level, while considering that Folding sofa is opened, cushion portion 11 can follow the moulding of protracting, need in handrail jacket 120, establish a block cloth 121 that can be driven by back support rod 3, its structure is that handrail jacket 120 is opened and put in place at Folding sofa, along the forward position of back support rod 3, is sewed with block cloth 121 one, by this block cloth 121, drives cushion portions 11 to open.
For another example Fig. 5, Fig. 1 and Fig. 3,120 times edges of described handrail jacket are not higher than 11 times edges of cushion portion, 130 times edges of backrest jacket are provided with vertical train of dress 131, the 120 times edges in 131 times edges of this train of dress and handrail jacket flush, and both sides are sewed together with handrail jacket 120 respectively, the outside that is trapped among cushion portion 11 by handrail jacket 120 and train of dress 131, both can increase the moulding of sofa body 1, also can improve the generous volume sense of sofa body 1.
With reference to Fig. 4, Fig. 5 and Fig. 6, because sofa body 1 is just set on feet, therefore can as convenient in Fig. 4 sofa body 1 be taken off to collection or clean, and sofa body 1 adopts flexible material to process, as oxford, and can, in processing such as oxford surface flocking, increase sofa feature and comfort level; Feet is by back and front supporting bar 2,3 and close that link rod 4 is hinged to be formed, and back and front supporting bar 2,3 can be folding along pin joint, and three can form intussusception, becomes one plane after folding, and as Fig. 6, volume is small and exquisite is convenient to collection.During assembling, the back and front supporting bar of feet 2,3 low-angles are opened, be first about to backrest jacket 130 be inserted in backrest section 21, again by handrail jacket 120 back support rod 3 upper ends, adjusting puts in place and goes and open again, and now, back and front supporting bar 2,3 maximum open angles are reinforced muscle band 5 and retrain; Along with human bady gravitational effect, back and front supporting bar 2,3 has toward trend that more wide-angle is opened, reacts on reinforcement band 5, and what make that it stretches tight is tighter, for armrest part 12 provides more hale and hearty support.
With reference to Fig. 2 and Fig. 5, described backrest jacket 130 outsides are provided with a band 6, band 6 two ends are stitched respectively solid on the backrest jacket 130 at backrest section 22 places, both sides, this band 6 after Folding sofa folding puts in place, can before turn over and fasten armrest part 12 front ends and back support rod 3 upper ends; This band 6 can be elastic cord, has certain deflection, can overturn easily and fasten armrest part 12 and back support rod 3 upper ends; Band 6 can be also the ribbon of end band eye-splice, after turning over, by eye-splice, fastens binding armrest part 12 and back support rod 3 upper ends before band.The design of band 6, makes the sofa after folding, and can not open voluntarily, is convenient to collection.
The utility model is different from existing folding seat maximum, is not have the support of cushion portion, has both simplified the design of feet, also weight reduction; And the sofa body of employing flexible material machine-shaping, its cushion portion is lift-on/lift-off type structure, is seated more soft comfortable, is also conducive to folding.
