Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
One interlock soft chair as shown in Fig. 1 ~ 3, comprises inner skeleton, and is coated on the filling core body 2 outside skeleton, and be coated on the integral type overcoat 4 of filling outside core body 2.
Skeleton comprises chair seat frame, chair back rack and U-shaped push rod 11 from front to back successively.Chair seat frame comprises front U-shaped seat bar 12, rear U-shaped seatpost 13 and Duo Gen seat support bracing piece 14.Front U-shaped seat bar 12 is in opening U-shape backwards, and many seat support bracing pieces 14 are equidistantly set in parallel between two U-shaped arms of front U-shaped seat bar 12.Rear U-shaped seatpost 13 is in the U-shaped opening part of front U-shaped seat bar 12, and rear U-shaped seatpost 13 is in opening U-shape forward, and two free ends of rear U-shaped seatpost 13 are separately positioned on two U-shaped arms of front U-shaped seat bar 12.Described chair back rack comprises chair back front bar 15, chair back rear bar 16, two chair back side levers 17 and Duo Gen chair back bracing piece 18.Two chair back side levers 17 be arranged in parallel, the leading section of chair back side lever 17 is hinged on by angle demodulator 3 on the free end of front U-shaped seat bar 12, and chair back front bar 15, many chair back bracing pieces 18 and chair back rear bar 16 are equidistantly set in parallel between two chair back side levers 17 from front to back successively.
Be provided with the seat 5 that links between U-shaped push rod 11 and chair back rack, the cross section of interlock seat 5 is in the shape of the letter V, and interlock seat 5 is connected by link rod 6 with between angle demodulator 3; Specifically the leading section of link rod 6 is hinged on angle demodulator 3, and the rearward end of link rod 6 is hinged on the leading section of interlock seat 5, and the middle part of interlock seat 5 is hinged in the rearward end of chair back side lever 17, and the free end of U-shaped push rod 11 is fixed in the rearward end of interlock seat 5.When the chair back keep flat be under deployed condition time, the front end of interlock seat is set level rear end and is tilted, and the U-shaped push rod making to be fixed in interlock base rear end portion is up dug, and the U-shaped push rod filled core body held up outside it forms the headrest for supporting head part; When the chair back up stirs, the front end that link rod orders about interlock seat tilts, the rearward end of interlock seat and on U-shaped push rod then turn over down and maintain an equal level mutually with chair back rack, now U-shaped push rod is as the extension of the chair back, not as headrest.Thus, this soft chair meets and does not use headrest taking under state, uses the different demands of headrest under supine position.
As shown in Figure 4, angle demodulator 3 comprises the first connector 31 and the second connector 32, first connector 31 is hinged by bearing pin a and the second connector 32.The first Access Division 312 that first connector 31 comprises the first socket part 311 and is connected with the first socket part 311 one.First Access Division 312 is hinged with ratchet 33 by bearing pin b, ratchet 33 is provided with for the torsional spring slot 331 for placing torsion spring, be 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.The second Access Division 322 that second connector 32 comprises the second socket part 321 and is connected with the second socket part 321 one.Second Access Division 322 is provided with the block 35 and multiple unidirectional gear teeth 36 that are connected as a single entity with it, multiple unidirectional gear teeth 36 are arranged along the inner end edges rule of the second Access Division 322, and forming 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 formed offsets formation ratchet wheel positioning mechanism.Second Access Division 322 is also coaxially arranged with spacer 37 along bearing pin a, described spacer 37 comprises outside cambered surface diameter and is greater than the location division that the reset portion 371 of the wheel flank of tooth and outside cambered surface diameter be less than 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 and ratchet 33 offset, are rotatably assorted, and locating aperture 372 and block 35 are rotatably assorted.
The first socket part 311 on first connector 31 is socketed on the free end of front U-shaped seat bar, and the second socket part 321 on the second connector 32 is socketed on chair back side lever leading section; Seat support and the chair back are by bearing pin a place coaxial rotation.The ratchet wheel positioning mechanism formed due to inner end and the unidirectional gear teeth 36 of ratchet 33 can only the clockwise one-directional rotation of the chair back, therefore the angle between seat support and the chair back is turned down, can regulate step by step according to the unidirectional gear teeth 36, in the scope that 180 ° go to 90 °, generally be used to adjusting back angle for sitting to user or lying; And the angle between seat support and the chair back is when being less than 90 °, 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, because the outside cambered surface diameter of reset portion 371 is greater than the wheel flank of tooth, therefore while reset portion 371 and ratchet 33 offset, remove ratchet 33 and engaging between the unidirectional gear teeth 36, now, the chair back can overlay on seat support, convenient for collecting; And if need the angle between seat support and the chair back to tune up, when generally going in the scope of 180 ° by 90 °, now need first angulation between the second connector 32 and the first connector 31 to be adjusted to be less than 90 °, when being less than 90 ° as mentioned above, while reset portion 371 and ratchet 33 offset, remove ratchet 33 and engaging between the unidirectional gear teeth 36; Now the second connector 32 and upper fixed stop 35 thereof rotate counterclockwise, spacer 37 and ratchet 33 offset and thus do not rotate, until after block 35 and the left side wall on spacer 37 offset, block 35 promotes spacer 37 and rotates counterclockwise until spacer 37 departs from ratchet 33, now ratchet 33 the inner is engaged with the unidirectional gear teeth 36 again, chair back expanded angle is maximum, is generally 180 °.
