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 backrest angle scalable soft chair as shown in Figure 1 and Figure 2, including the base 1 being below, and the seat support 2 being arranged on base 1, and arranges the handrail 5 of seat support 2 both sides, and the chair back 4 being arranged on seat support 2.
Base 1 includes base skeleton, and is coated on the base sheath outside base skeleton.Base skeleton is made up of two U-shaped bottom bars 13 of circular bottom bar 12 and upper setting thereof,
The U-shaped of U-shaped bottom bar 13 is opening down, and two free ends of U-shaped bottom bar 13 are fixedly connected with on circular bottom bar 12, and two U-shaped bottom bars 13 are symmetrical along direction centrage before and after circular bottom bar 12.
Seat support 2 includes seat support skeleton, and is coated on the seat support filling core body 21 outside seat support skeleton, and is coated on the seat support set outside seat support filling core body 21.Described seat support skeleton includes U-shaped seat bar 23 and two reinforcement connecting rods 24, the U-shaped opening of U-shaped seat bar 23 is backwards, strengthening connecting rod 24 to be in the U-shaped opening of U-shaped seat bar 23, the both ends strengthening connecting rod 24 are fixedly connected on two U-shaped arms of U-shaped seat bar 23 respectively.Two reinforcement connecting rods 24 are arranged in parallel, strengthen connecting rods 24 for two and are connected with two U-shaped bottom bars 13 by bolt fixing respectively.
Handrail 5 includes bar 51, and is coated on the handrail filling core body 52 outside bar 51, and is coated on the armrest sheath outside handrail filling core body 52.The projection up and down of bar 51 and left and right project the shape that all takes the shape of the letter U.The bar 51 of both sides is oppositely arranged, and the free end inside bar 51 is fixedly connected on the U-shaped facies lateralis brachii of U-shaped seat bar 23, and the outer end of bar 51 is bent upwards.
The chair back 4 includes that U-shaped carries on the back bar 41, and is coated on the chair back filling core body 42 outside U-shaped back of the body bar 41, and is coated on the chair back set outside chair back filling core body 42.The U-shaped opening of described U-shaped back of the body bar 41 matches with the U-shaped openings of sizes of U-shaped seat bar, two free ends of U-shaped back of the body bar 41 are respectively hinged on two free ends of U-shaped seat bar 23 by angle demodulator 3, being provided with link rod 6 between two angle demodulators 3, the both ends of link rod 6 are separately fixed on the angle demodulator 3 of both sides.
As it is shown on figure 3, 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 angle of back-rest regulative mode of this soft chair: the first socket part 311 on the first connector 31 is socketed on the free end of U-shaped seat bar, the second socket part 321 on the second connector 32 is socketed on U-shaped back of the body bar free end；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 °.
In sum, the advantage of this soft chair is: 1, and the chair back of this soft chair is hinged on seat support by angle demodulator, can adjust angle of back-rest by angle demodulator during use, and taking or dossing for different angles, adaptability is good；2, seat support both sides are provided with handrail, and the handrail of both sides is then as hand rest portion when taking, and comfort is high；3, the lower end of soft chair is provided with base, and the base skeleton of chassis interior includes that two U-shaped bottom bars of circular bottom bar and upper setting thereof are constituted, and two free ends of U-shaped bottom bar are fixedly connected with on circular bottom bar, and seat support is bolted on two U-shaped bottom bars of base；Circular bottom bar adds the support area on chassis, thus promotes base holding strength；U-shaped bottom bar improves the support height on chassis, so that seat support will not directly contact with ground, the seat support of base upper end, the chair back and handrail are difficult to make dirty, and seat bottom not cracky, is suitable for indoor and outdoor and uses.
