Detailed description of the invention
Below in conjunction with the accompanying drawings, the preferred embodiments of the invention are described in further detail.
One as shown in Figure 1 and Figure 2 folds soft chair with back, including the integral type overcoat 1 in outside, and the filling core body 2 being coated in integral type overcoat 1, and it is coated on the chair framework filled in core body 2；Chair framework includes chair seat frame 5, chair back rack 6 and the pillow 7 set gradually from bottom to up.
Chair seat frame 5 includes that U-shaped mobile jib 51, front U-shaped bar 52, rear U-shaped bar 53, seat support strengthen link rod 54 and two support bars 55.Backwards, the rear portion of two U-shaped arms of U-shaped mobile jib 51 is bent upwards the U-shaped opening of U-shaped mobile jib 51.Front U-shaped bar 52 is inclined on U-shaped mobile jib 51, and two free ends of front U-shaped bar 52 are fastened on two U-shaped arm leading sections of U-shaped mobile jib 51 respectively.Seat support is strengthened between the bending section 51a that link rod 54 is horizontally installed on U-shaped mobile jib 51, and seat support is strengthened the both ends of link rod 54 and is all connected with being fixed on the bending section 51a free end of U-shaped mobile jib 51.Before forward, two free ends of rear U-shaped bar 53 are all connected with being fixed on two U-shaped facies medialis brachiis of U-shaped mobile jib 51 the U-shaped opening of rear U-shaped bar 53, and junction is in the bending section 51a of U-shaped mobile jib 51.The bottom of two support bars 55 is fastened in two U-shaped arm rearward end of rear U-shaped bar 53 respectively, and upper end is separately fixed on the bending section 51a free end of U-shaped mobile jib 51.Chair back rack 6 includes two chair back side levers 61 be arrangeding in parallel, and the bottom of chair back side lever 61 is hinged on the bending section 51a free end of U-shaped mobile jib 51 by angle of back-rest actuator 3, and the upper end of chair back side lever 61 bends backward.Pillow 7 includes that link rod 72 strengthened by U-shaped push rod 71 and headrest, and two free ends of U-shaped push rod 71 are respectively hinged on the upper end of two chair back side levers 61 by headrest angle demodulator 4.Headrest is strengthened link rod 72 and is horizontally installed between two head pillow angle demodulators 4, and headrest is strengthened the both ends of link rod 72 and is fastened on respectively on the medial surface of headrest angle demodulator 4.
As shown in Fig. 2 ~ 3, angle of back-rest actuator 3 is identical with the structure of headrest angle demodulator 4, all includes that the first connector 31 and the second connector 32, the first connector 31 are hinged by bearing pin a and the second connector 32.First connector 31 includes the first socket part 311 and the first Access Division 312 being connected with the first socket part 311 one.It is hinged with ratchet 33 by bearing pin b on first Access Division 312, ratchet 33 is provided with the torsional spring slot 331 for placing torsion spring, being provided with torsion spring 34 in torsional spring slot, the middle part of torsion spring 34 is set on bearing pin b, and two free ends of torsion spring 34 are stuck on the inner end of the first socket part 311 respectively.Second connector 32 includes the second socket part 321 and the second Access Division 322 being connected with the second socket part 321 one.Second Access Division 322 is provided with the block 35 being connected as a single entity with it and multiple unidirectional gear teeth 36, multiple unidirectional gear teeth 36 are arranged along the inner end edges rule of the second Access Division 322, and constituting the wheel flank of tooth each other, the wheel flank of tooth that the inner end of ratchet 33 and the unidirectional gear teeth 36 are constituted offsets composition ratchet wheel positioning mechanism.Spacer 37 also it is coaxially arranged with along bearing pin a on second Access Division 322, described spacer 37 include outside cambered surface diameter more than the wheel reset portion 371 of the flank of tooth and outside cambered surface diameter less than the location division of the wheel flank of tooth, location division is provided with locating aperture 372, and block 35 is in locating aperture 372.When spacer 37 rotates along bearing pin a, reset portion 371 offsets with ratchet 33, is rotatably assorted, and locating aperture 372 is rotatably assorted with block 35.
The angle of back-rest regulative mode of this soft chair with back: the first socket part of angle of back-rest actuator is socketed on the bending section free end of U-shaped mobile jib, and the second socket part is socketed on the bottom of chair back side lever；The ratchet wheel positioning mechanism constituted due to inner end and the unidirectional gear teeth 36 of ratchet 33 can only chair back one-directional rotation clockwise, therefore the angle [alpha] between seat support and the chair back is turned down, can be adjusted step by step according to the unidirectional gear teeth 36, be taken to user by adjusting back.And the angle [alpha] between seat support and the chair back less than certain angle time, block 35 on second connector 32 promotes locating aperture 372 right side wall of spacer 37, spacer 37 is rotated clockwise along bearing pin a, the reset portion 371 of spacer 37 offsets with the inner end of ratchet 33, extrudes, owing to the outside cambered surface diameter of reset portion 371 is more than the wheel flank of tooth, therefore, while reset portion 371 and ratchet 33 offset, engaging between ratchet 33 and the unidirectional gear teeth 36 is released；Now, on the one hand the chair back can be able to be overlayed on seat support, convenient for collecting；On the other hand the angle [alpha] between seat support and the chair back can be tuned up, because the reset portion 371 of spacer 37 offsets with ratchet 33, release engaging between ratchet 33 and the unidirectional gear teeth 36；When second connector 32 and upper fixed stop 35 thereof are rotated counterclockwise, spacer 37 then offsets with ratchet 33 thus does not rotates, until after block 35 offsets with the left side wall on spacer 37, block 35 promotes spacer 37 to rotate counterclockwise until spacer 37 departs from ratchet 33, ratchet 33 the inner is engaged with the unidirectional gear teeth 36 again, and chair back expanded angle α is maximum.
The headrest angular adjustment of this soft chair with back: the first socket part of headrest angle demodulator is socketed in the upper end of chair back side lever, and the second socket part is socketed in two free ends of U-shaped push rod；The structure of headrest angle demodulator is identical with angle of back-rest actuator, and its occupation mode is referring also to the occupation mode of above-mentioned angle of back-rest actuator.
