The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the invention are described in further detail.
A kind of folding cushion as shown in Fig. 1 ~ Fig. 2, comprises base body 1 and backrest body 2.
Base body 1 comprises base skeleton, and the base filling core body 11 that is coated on base skeleton outside, and is coated on the base overcoat that base is filled core body 11 outsides.Base skeleton comprises front U-shaped seat bar 12, rear U-shaped seat bar 13, base bracing piece 14 and two foundation seat U-shaped side levers 15.Front U-shaped seat bar 12 and rear U-shaped seat bar 13 arrange in opposite directions, and backwards, in the U-shaped opening of rear U-shaped seat bar 13 in front U-shaped seat bar 12, two U-shaped arms of rear U-shaped seat bar 13 are separately fixed on the free end of front U-shaped seat bar 12 opening direction of front U-shaped seat bar 12.Base bracing piece 14 is longitudinally arranged between front U-shaped seat bar 12 and rear U-shaped seat bar 13, and the leading section of base bracing piece 14 is fixed on front U-shaped seat bar 12 middle parts, and rearward end is fixed on rear U-shaped seat bar 13 middle parts.Two foundation seat U-shaped side levers 15 are arranged on the left and right sides of front U-shaped seat bar 12 in opposite directions, and the free end of two foundation seat U-shaped side levers 15 is hinged on respectively on two U-shaped arms of front U-shaped seat bar 12 by angle demodulator 3.
Backrest body 2 comprises backrest frames, and the backrest filling core body 21 that is coated on backrest frames outside, and is coated on the backrest overcoat that backrest is filled core body 21 outsides.Backrest frames comprises U-shaped back of the body bar 22, backrest bracing piece 23, backrest link rod 24 and two backrest U-shaped side levers 25, the U-shaped opening of U-shaped back of the body bar 22 mates with the U-shaped openings of sizes of front U-shaped seat bar 12, and two free ends of U-shaped back of the body bar 22 are hinged on the free end of front U-shaped seat bar 12 by angle demodulator 3.Described backrest link rod 24 is horizontally installed between two U-shaped arms of U-shaped back of the body bar 22, the both ends of backrest link rod 24 are fastened on respectively two U-shaped arm inner sides of U-shaped back of the body bar 22, backrest bracing piece 23 is longitudinally arranged between backrest link rod 24 and U-shaped back of the body bar 22, the leading section of backrest bracing piece 23 is fixed on backrest link rod 24 middle parts, and rearward end is fixed on U-shaped back of the body bar 22 middle parts.Two backrest U-shaped side levers 25 are arranged on the left and right sides of U-shaped back of the body bar 22 in opposite directions, and the free end of two backrest U-shaped side levers 25 is hinged on respectively on two U-shaped arms of U-shaped back of the body bar 22 by angle demodulator 3.
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.
Backrest body 2 regulative modes of this folding cushion: the first socket part 311 on the first connector 31 of angle demodulator 3 is socketed on the free end of front U-shaped seat bar, the second socket part 321 on the second connector 32 is socketed on U-shaped back of the body bar 212 free ends; Base body 1 and backrest body 2 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 backrest body 2, therefore the angle between base body 1 and backrest body 2 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 backrest body 2 angles for taking to user or dossing; And when the angle between base body 1 and backrest body 2 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, backrest body 2 can overlay on base body 1, convenient for collecting; And if the angle between base body 1 and backrest body 2 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, and backrest body 2 keeps flat expansion.
When backrest frames is at an angle during slant setting, whole folding cushion is used as many people position seat, on the base U-shaped side lever of front U-shaped seat bar and both sides thereof, may be used to take; And when backrest frames horizontal positioned, whole folding cushion can be used as the double pad of lying, all can be for dossing on base body and backrest body, in addition, turnover all can be realized by angle demodulator in the two ends, left and right of base body 1 and the two ends, left and right of backrest body 2, and on base U-shaped side lever and backrest U-shaped side lever, turn over certain angle, can be used as headrest or the pin holder while dossing, so this folding cushion has novel structure, the diversified feature of occupation mode.
