The specific embodiment
Below in conjunction with the Figure of description providing, preferred embodiment of the present utility model is made to description.
As shown in Figure 1 and Figure 2, the utility model multifunction sofa brandreth 1 comprise seat 10, lean against frame 11, underframe 12, side plate 13, driving shaft 14, extension means 15, support adjustment mechanism and extension spring 16.
On biside plate 13, be also fixed with a cross bar 131, cross bar 131 protrudes out forward and is provided with three montants, 132, one circular shafts 133 through the front end of three montants 132 and is fixed on montant 132.A connecting rod in extension means 15 is articulated in circular shaft 133 and drives circular shaft 133 to move up or down around cross bar 131 in the time stretching or retract.
A montant 132 in the middle of being positioned at is provided with the tooth plate 134 of downward-extension on one day, and tooth plate 134 is articulated in this montant 132, and the limit that tooth plate 134 has an arc notch and arc notch forms multiple engaging tooths.
Support adjustment mechanism comprises trace 17 and is articulated in the vertical rod 18 of front-axle beam 120, the upper end of vertical rod 18 is fixed with engaging cross bar 180, engaging cross bar 180 engages with tooth plate 134, one end of trace 17 is articulated in vertical rod 18, the other end is articulated in an iron plate that is fixed on driving shaft 14, and trace 17 promotes vertical rod 18 and swings and then make to engage cross bar 180 and engage or depart from tooth plate 134 by the rotation of driving shaft 14.Between vertical rod 18 and front-axle beam 120, be provided with torsion spring 181, torsion spring 181 provides and the upper end of vertical rod 18 is swung forward and away from the elastic force of driving shaft 14, the effect of torsion spring 181 is to guarantee that engaging cross bar 180 is more firm with engaging of tooth plate 134.
The elastic force that extension spring 16 is arranged between the back rest 121 and driving shaft 14 and provides auxiliary extension means 15 to retract.Particularly, multifunction sofa brandreth 1 also comprises the first tension spring connecting piece 16a and the second tension spring connecting piece 16b, one end of the second tension spring connecting piece 16b is bent to form hook solid, one end of the first tension spring connecting piece 16a is sheathed and be fixed on driving shaft 14, the other end of the first tension spring connecting piece 16a is articulated in one end of the second tension spring connecting piece 16b, one end of the other end of the second tension spring connecting piece 16b and extension spring 16 is fixed, and the other end of extension spring 16 is fixed on the back rest 121.After being arranged so that of extension spring 16 engages cross bar 180 and tooth plate 134 and depart from and engage, driving shaft 14 has the trend of automatic rotating, and therefore occupant can be more laborsaving in the time that the pin of back retracting leans on.
The front end of seat 10 is articulated in circular shaft 133, and the rear end of seat 10 is installed on underframe 12, and the lower end that leans against frame 11 is articulated in seat 10.Concrete, the end of seat 10 upwards protrudes out and is provided with pin joint seat 101, the lower end that leans against frame 11 is articulated in described pin joint seat 101 and has the linkage part 111 that downward bending is extended, the lower end of described linkage part 111 is articulated in a spout 112, on described spout 112, offer chute 113, the lower end of described seat 10 is fixed with to slide and is arranged at the pin 102 in described chute 113.Pin 102 in the time of the interior slip of chute 113, thereby lean against frame 11 just relatively seat 10 pivotables change angles of inclination.
In conjunction with Fig. 3 and Fig. 4, after extension means 15 stretches out, be fixed on the pin of holder 150 by the relative seat 10 away from multifunction sofa brandreth 1, circular shaft 133 upwards swings under the promotion of extension means 15, meanwhile, the front end of the seat 10 being connected with circular shaft 133 is upwards lifted, seat 10 and lean against the angle that frame 11 tilts and changed, occupant can use the more comfortable posture of leisure, and now multifunction sofa brandreth 1 presents the second use state.Under the second use state, occupant can by change position of centre of gravity to pin by exerting pressure, thereby make extension means 15 produce retraction to a certain degree, and the retraction of extension means 15 drives engaging cross bars 180 to engage with tooth plate 134 disengagings by driving shaft 14 and trace 17, now occupant can change seat 10 and lean against the hypsokinesis angle of frame 11.The adjustment angle variation that repeats to make multifunction sofa brandreth 1 of said process.
With reference to Fig. 5, under the second use state, lean against frame 11 can be further relatively seat 10 pivotables further to change the angle of inclination that leans against frame 11, thereby occupant can be couched on sofa, now multifunction sofa brandreth 1 presents the 3rd use state.
In the present embodiment, front-axle beam 120, the back rest 121, left beam 122, right beam 123, driving shaft 14 and cross bar 131 all adopt square tubing to improve intensity.
Compared with prior art, the beneficial effects of the utility model are: seat 10 is installed on underframe 12, and the front end of seat 10 is articulated in circular shaft 133, therefore in the time of rotating driveshaft 14, extension means 15 stretches out or retracts, and meanwhile seat 10 can be followed the action of extension means 15 and be changed angle of inclination, realizes the seat support of sofa and leans against in the time adjusting, follow pin by motion together with this, and do not need to adjust respectively seat support, lean against and pin leans on, make the process adjusted convenient.Meanwhile, support adjustment mechanism not only provides support for extension means 15, more makes seat 10 have more adjustment angle by tooth plate 134 and the cooperation that engages cross bar 180.
Above disclosed is only preferred embodiments of the present utility model, its effect is facilitate those skilled in the art to understand and implement according to this, certainly can not limit with this interest field of the utility model, therefore the equivalent variations of doing according to the utility model claim, still belongs to the scope that the utility model is contained.
