The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the invention are described in further detail.
The adjustable soft chair of a kind of backrest angle as shown in Figure 1 and Figure 2, comprises the base 1 in below, and is arranged on the seat support 2 on base 1, and the handrail 5 that seat support 2 both sides are set, and is arranged on the chair back 4 on seat support 2.
Base 1 comprises base skeleton, and the base sheath that is coated on base skeleton outside.Base skeleton consists 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, two free ends of U-shaped bottom bar 13 are all fixedly connected on circular bottom bar 12, and two U-shaped bottom bars 13 are symmetrical along the fore-and-aft direction center line of circular bottom bar 12.
Seat support 2 comprises seat support skeleton, and the seat support filling core body 21 that is coated on seat support skeleton outside, and is coated on the seat support cover that seat support is filled core body 21 outsides.Described seat support skeleton comprises U-shaped Zuo Gan 23He Lianggen reinforced company extension bar 24, the U-shaped opening of U-shaped seat bar 23 backwards, in the U-shaped opening of reinforced company's extension bar 24 in U-shaped seat bar 23, the both ends of reinforced company's extension bar 24 are fixedly connected on respectively on two U-shaped arms of U-shaped seat bar 23.Liang Gen reinforced company extension bar 24 is arranged in parallel, and Liang Gen reinforced company extension bar 24 is connected and fixed with two U-shaped bottom bars 13 respectively by bolt.
Handrail 5 comprises bar 51, and the handrail filling core body 52 that is coated on bar 51 outsides, and is coated on the armrest sheath that handrail is filled core body 52 outsides.The projection up and down of bar 51 and the left and right projection shape that all takes the shape of the letter U.The bar 51 of both sides arranges in opposite directions, and the free end of bar 51 inner sides 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 comprises U-shaped back of the body bar 41, and the chair back filling core body 42 that is coated on U-shaped back of the body bar 41 outsides, and is coated on the chair back set that the chair back is filled core body 42 outsides.The U-shaped opening of described U-shaped back of the body bar 41 and the U-shaped openings of sizes of U-shaped seat bar match, two free ends of U-shaped back of the body bar 41 are hinged on respectively on two free ends of U-shaped seat bar 23 by angle demodulator 3, between two angle demodulators 3, be provided with link rod 6, the both ends of link rod 6 are respectively fixedly on the angle demodulator 3 of both sides.
As shown in Figure 3, angle demodulator 3 comprises that the first connector 31 and the second connector 32, the first connectors 31 are hinged by bearing pin a and the second connector 32.The first connector 31 comprises the first socket part 311 and the first Access Division 312 being connected with the first socket part 311 one.On the first Access Division 312, by bearing pin b, be hinged with ratchet 33, ratchet 33 is provided with for for placing the torsional spring slot 331 of torsion spring, in torsional spring slot, be provided with torsion spring 34, it is upper that the middle part of torsion spring 34 is set in bearing pin b, and two free ends of torsion spring 34 are stuck in respectively on the inner end of the first socket part 311.The second connector 32 comprises the second socket part 321 and the second Access Division 322 being connected with the second socket part 321 one.The second Access Division 322 is provided with block 35 and a plurality of unidirectional gear teeth 36 that are connected as a single entity with it, a plurality of unidirectional gear teeth 36 arrange along the inner end regular edges of the second Access Division 322, and form each other the wheel flank of tooth, the wheel flank of tooth that the inner end of ratchet 33 and the unidirectional gear teeth 36 the form formation ratchet wheel positioning mechanism that offsets.On the second Access Division 322, along bearing pin a, be also coaxially arranged with spacer 37, described spacer 37 comprises that outside cambered surface diameter is greater than the reset portion 371 of the wheel flank of tooth and the location division that outside cambered surface diameter is 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 offsets, is rotatably assorted with ratchet 33, 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 bearing pin a place coaxial rotation.The ratchet wheel positioning mechanism forming 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, generally at 180 °, go in the scope of 90 ° and be used to adjusting back angle for sitting or lie to user; And when the angle between seat support and the chair back is less than 90 °, block 35 on the second connector 32 promotes locating aperture 372 right side walls of spacer 37, spacer 37 is clockwise rotated along bearing pin a, the reset portion 371 of spacer 37 offsets, pushes with the inner end of ratchet 33, because the outside cambered surface diameter of reset portion 371 is greater than the wheel flank of tooth, when therefore reset portion 371 offsets with ratchet 33, remove the engagement between ratchet 33 and the unidirectional gear teeth 36, now, the chair back can overlay on seat support, convenient for collecting; And if the angle between seat support and the chair back need to be tuned up, while 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 and to be less than 90 °, while being less than as mentioned above 90 °, when reset portion 371 offsets with ratchet 33, remove the engagement between ratchet 33 and the unidirectional gear teeth 36; Now the second connector 32 and upper fixed stop 35 thereof rotate counterclockwise, 37 of spacers offset with ratchet 33 thereby do not rotate, until after block 35 offsets with left side wall on spacer 37, block 35 promotion spacers 37 rotate counterclockwise until spacer 37 departs from ratchets 33, now mesh with the unidirectional gear teeth 36 again ratchet 33 the inners, chair back expanded angle is maximum, is 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, during use, can adjust angle of back-rest by angle demodulator, and for the taking or dossing of different angles, adaptability is good; 2, seat support both sides are provided with handrail, and the handrail of both sides is the 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 base inside comprises that two U-shaped bottom bars of circular bottom bar and upper setting thereof form, and two free ends of U-shaped bottom bar are all fixedly connected on circular bottom bar, and seat support is bolted on two U-shaped bottom bars of base; Circular bottom bar makes to have increased the support area on chassis, thereby promotes base holding strength; U-shaped bottom bar has promoted the support height on chassis, thereby seat support can directly not contacted with ground, and the seat support of base upper end, the chair back and handrail are difficult for making dirty, and seat bottom cracky not, applicable indoor and outdoor use.
