Abstract
The utility model discloses a sofa with the pressure regulation for the inclination of backrest, which is composed of a stent, a cushion frame, a backrest and a regulation mechanism of the back rest inclination. The regulation mechanism of the back rest inclination is composed of a sliding bush pivoted on the stent, fastening sleeves and an angular slider jacketed on the sliding bush. Both ends of the angular slider are fixed below the cushion frame, and the sliding bush is disposed between two fastening sleeves provided with the fastening bolts. The upper end of the backrest can also be hinged with a small backrest. The back rest of this sofa with the pressure regulation for the inclination of backrest can be in arbitrary adjustment between 0 to 90 degree, and the adjustment is simple and convenient.
Description
Technical field
The utility model relates to a kind of sofa, the sofa that particularly a kind of backrest inclination degree can be adjusted arbitrarily in 0-90 degree angle.
Background technology
The backrest of existing husky bed and some sofas all can be movable, can adjust its angle of inclination, with the needs that adapt to people's different seat appearance or couch.General all is by on the base of sofa or divan and backrest a tilt adjusting apparatus being installed, and this device is generally realized above-mentioned functions by pin and pin-hole arrangement, ratchet device or other briar tooth device.But its backrest of the sofa of this structure can only be adjusted in several default angles, can not adjust in 0-90 degree angle according to people's concrete needs.
The utility model content
At the problems referred to above that present sofa exists, the purpose of this utility model is to provide a kind of pressure to regulate backrest inclination degree sofa, and the backrest of this sofa can rotate inclination arbitrarily in 0-90 degree angle.
To achieve these goals, pressure of the present utility model regulate backrest inclination degree sofa comprise support, be hinged on backrest on the support, with hinged seat frame and the bevel angle adjustment mechanism in backrest lower end.Bevel angle adjustment mechanism is made of sliding sleeve, adapter sleeve and dihedral slide bar, sliding sleeve, adapter sleeve are articulated on the sofa support, and sliding sleeve is positioned in the middle of two adapter sleeves, and the dihedral slide bar is through on the sliding sleeve, two adapter sleeves are clipped in the middle the dihedral slide bar, and a fastening bolt is arranged on two adapter sleeves; The two ends of dihedral slide bar be fixed in seat frame below.
Can a spacing convex surface of sliding sleeve be arranged punching press on the above-mentioned dihedral slide bar, the maximum sliding distance of restriction slide bar in sliding sleeve is to define the angle of inclination of sofa backrest.
Above-mentioned bevel angle adjustment mechanism as required can be for a plurality of.
Above-mentioned sliding sleeve and adapter sleeve can be enclosed within on the stay pipe that is fixed on the sofa support, as the slip hinge and the load-bearing strong point.
Above-mentioned backrest upper end can also a hinged backrest that can rotate in 0-90 degree angle, is used for by putting head.
During use, people's leans back, the rotation that recedes of sofa backrest, it is big that gradient becomes, its lower end seat frame hinged with it passed forward, is fixed in dihedral slide bar below the seat frame in the sliding sleeve slides forwards, and sliding sleeve is that the center of circle turns over certain angle with meeting with its drive-connecting shaft also simultaneously.When the people sits forward, can make the seat frame rear portion to lower stress, the hot frame of seat serves as the circular certain angle that changes with the sliding sleeve pivot just, simultaneously, slide bar slides in sliding sleeve backward, and seat frame is moved to the sofa rear portion, and drives backrest and rotate forward, and its gradient is diminished.Can make the fastened location of slide bar by the fastening bolt of adjusting on the adapter sleeve after angle adjustment is suitable.Position-limiting action can be played in the knuckle limit of positioning convex on the slide bar and another side, and slide bar can only be slided between spacing point, guarantees that the sofa backrest only rotates arbitrarily in the 0-90 degree angle that limits.
In sum, the backrest of sofa of the present utility model can tilt arbitrarily in the 0-90 angle, and only needs to change the adjustment action that sitting posture just can be finished the gradient of its backrest by the user, and is easy to use.People can select arbitrarily to make its comfortable sitting posture like this, or forward the sofa backrest to water level and put, and use as bed.
Description of drawings
Description of drawings is as follows:
Fig. 1 is the side view that pressure is regulated backrest inclination degree sofa;
Fig. 2 is the structure chart that pressure is regulated the tilt adjusting apparatus of backrest inclination degree sofa.
The specific embodiment
Below in conjunction with accompanying drawing pressure of the present utility model being regulated backrest inclination degree sofa is described further:
As shown in Figures 1 and 2, pressure regulate backrest inclination degree sofa comprise support 1, seat frame 6, with the hinged backrest 7 of an end of seat frame, backrest 7 has a bending, and its bending part is hinged on the support, but at the little backrest 8 of the hinged something or somebody to fall back on of the other end of backrest 7.
A stay pipe 3 is arranged on support, an ABS sliding sleeve 4 and two ABS adapter sleeves 9 are enclosed within on the stay pipe 3, sliding sleeve 4 is positioned in the middle of two adapter sleeves 9, a dihedral slide bar 5 passes sliding sleeve 4, two ends are fixed in below the sofa seat poppet 6 by screw, stamp out a convex surface 11 back spacing as sliding sleeve on one side of dihedral slide bar 5, the bending part of dihedral slide bar 5 is as the front limit of sliding sleeve, dihedral slide bar 5 before and after having only the part between spacing can sliding sleeve 4 in, slide, can only inclination in certain angle (being 0-90 ° in this example) thereby define sofa backrest 7; A fastening bolt 10 is housed on two adapter sleeves 9, can fastens being positioned at two adapter sleeves, 9 middle dihedral slide bars 5 two adapter sleeves 9 to the centre tension by fastening bolt 10.
The people who is sitting on the sofa wants to make sofa backrest 7 to recede, as long as back leans on backward, just can make backrest 7 serves as axially back rotation with the hinged fulcrum of itself and support, just rotate to the front upper place bottom of backrest 7, promoting the seat frame 6 hinged with it moves forward, slide 5 bars just in sliding sleeve 4 slides forwards with the dihedral that seat frame 6 is fixed together, making sliding sleeve 4 simultaneously serves as that axle turns over an angle with stay pipe 3.
If the gradient of sofa backrest 7 is diminished, be sitting in the people on the sofa as long as sit forward, its center of gravity reach, just can be to the hinged end of down pressing seat poppet 6 and backrest 7, because it is hinged with backrest 7, seat frame 6 just moves to the back lower place, slide bar 5 slip backward in sliding sleeve 4 simultaneously.This moment, backrest 7 rotated forward, and its gradient diminishes.
After backrest 7 angle adjustment are good, as long as tighten trip bolt 10 on the adapter sleeve 9, slide bar 5 is clamped, seat frame 6 can not be moved, just the backrest 7 of sofa is fixed on this gradient.
The hinged little backrest 8 in sofa backrest 7 upper ends can rotate in 0-90 degree angle according to the needs that head leans on.
So pressure of the present utility model is regulated backrest inclination degree sofa, how the user just utilizes the extruding of people's body weight to change the angle of inclination of sofa backrest arbitrarily as long as change sitting posture, make people feel that the posture of the most comfortable sits or be recumbent on a sofa with it, not only take pleasantly, and the angle of inclination of backrest is easy to adjust.
