Abstract
The invention relates to the field of household articles, and discloses a linkage soft chair. A chair back frame of the linkage soft chair is hinged with a seat frame through an angle adjuster; a linkage base is arranged between a U-shaped push rod and the chair back frame, and is connected with the angle adjuster through a link bar; the front end part of the link bar is hinged with the angle adjuster; and the rear end part of the link bar is hinged with the front end part of the linkage base. When the chair back is kept flat in an unfolded state, the front end of the linkage base is kept flat and the rear end upwarps, and the U-shaped push rod fixed on the rear end part of the linkage base upwarps, and lifts up a filling core body on the outer side to form a headrest for supporting the head; when the chair back turns upwards, the link bar drives the front end of the linkage base to upwarp, the rear end part of the linkage base and the U-shaped push rod on the linkage base turn downwards, and are level with the chair back frame, and the U-shaped push rod is used as extension of the chair back and not used as the headrest. Therefore, the soft chair can meet different requirements that the headrest is not used in the taking state, and is used in the supine state.
Description
Technical field

Detailed description of the invention
Below in conjunction with the accompanying drawings, the preferred embodiments of the invention are described in further detail.
A kind of linkage soft chair as shown in Fig. 1 ~ 3, including internal skeleton, and is coated on the filling core body 2 outside skeleton, and is coated on the integral type overcoat 4 filled outside core body 2.
Skeleton includes chair seat frame, chair back rack and U-shaped push rod 11 the most successively.Chair seat frame includes 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 U-shape backwards in opening, 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 U-shape forward in opening, 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 includes chair back front bar 15,16, two chair back side lever 17 and Duo Gen chair back bracing pieces 18 of chair back rear bar.Two chair back side levers 17 be arranged in parallel, the leading section of chair back side lever 17 is hinged on the free end of front U-shaped seat bar 12 by angle demodulator 3, and chair back front bar 15, many chair back bracing pieces 18 and chair back rear bar 16 are the most equidistantly set in parallel between two chair back side levers 17.
Being provided with linkage seat 5 between U-shaped push rod 11 and chair back rack, the cross section of linkage seat 5 is in the shape of the letter V, and is connected by link rod 6 between linkage seat 5 and angle demodulator 3；The specifically 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 linkage seat 5, and the middle part of linkage 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 linkage seat 5.When the chair back keeps flat and is under deployed condition, the front end of linkage seat is set level rear end and is tilted, and makes the U-shaped push rod being fixed in linkage base rear end portion up dig, and U-shaped push rod holds up the filled core body outside it and forms the headrest for supporting head part；When the chair back up stirs, link rod orders about the front end of linkage seat and tilts, and rearward end and the U-shaped push rod thereon of linkage seat turn over down and maintain an equal level mutually with chair back rack, and 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 under taking state, uses the different demands of headrest under supine position.
As shown in Figure 4, angle demodulator 3 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 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 rotating coaxially at bearing pin a.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 between seat support and the chair back is turned down, can be adjusted step by step according to the unidirectional gear teeth 36, typically go to be used to adjusting back angle in the range of 90 ° for sitting to user or lying at 180 °；And the angle between seat support and the chair back less than 90 ° 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, release engaging between ratchet 33 and the unidirectional gear teeth 36, now, the chair back can overlay on seat support, convenient for collecting；And if need to tune up the angle between seat support and the chair back, when typically being gone in the range of 180 ° by 90 °, now need first to regulate angulation between the second connector 32 and the first connector 31 to less than 90 °, time as mentioned above less than 90 °, while reset portion 371 and ratchet 33 offset, release engaging between ratchet 33 and the unidirectional gear teeth 36；Now the second connector 32 and upper fixed stop 35 thereof rotate 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, now ratchet 33 the inner is engaged with the unidirectional gear teeth 36 again, chair back expanded angle is maximum, generally 180 °.
