The specific embodiment:
Referring to Fig. 1～Fig. 6, one end of the bottom linker 1 of the utility model embodiment something or somebody to fall back on backrest linkage and driving connector 2 is rotationally connected by the first rotating shaft A, the other end that drives connector 2 is rotationally connected by the second rotating shaft B with an end that stops connector 4, the other end that stops connector 4 is connected support 6 with lifting connector 3 and backrest and is rotationally connected by the 4th rotating shaft D, backrest connects support 6 and fixedlys connected with backrest 8, the other end of lifting connector 3 and pipe fitting support 7 are rotationally connected by the 3rd rotating shaft C, pipe fitting support 7 is fixedlyed connected with something or somebody to fall back on pipe fitting 9, top connecting plate 11 is installed on the backrest 8, top connecting plate 11 has two something or somebody to fall back on pipe fitting holes 17 simultaneously, lining 12 is embedded in 17 li in the something or somebody to fall back on pipe fitting hole of top connecting plate 11, something or somebody to fall back on pipe fitting 9 passes lining 12, something or somebody to fall back on mounting bracket 13 is installed in the top of something or somebody to fall back on pipe fitting 9, stablize connecting rod 10 and pipe fitting support 7, something or somebody to fall back on pipe fitting 9 is fixedly connected, stop to be equipped with on the connector 4 spacing pin 5, a lifting connector groove 30 is arranged on the lifting connector 3, the two ends of lifting connector groove 30 are respectively confined planes 1 and confined planes 2 32, and spacing pin 5 can slide in the lifting connector groove 30 of lifting connector 3.
As a kind of special case, backrest 8 and top connecting plate 11 constitute backrest module, and backrest 8 or top connecting plate 11 are provided with pilot hole 18, and pilot hole 18 is used for locating and guiding something or somebody to fall back on pipe fitting 9.When backrest 8 was provided with pilot hole 18, top connecting plate 11 can be provided with something or somebody to fall back on pipe fitting hole 17, and something or somebody to fall back on pipe fitting 9 passes pilot hole 18 and passes something or somebody to fall back on pipe fitting hole 17 simultaneously.
As another kind of special case, backrest module only comprises backrest 8, and backrest 8 is provided with pilot hole 18, and pilot hole 18 is used for locating and guiding something or somebody to fall back on pipe fitting 9.
Referring to Fig. 2, something or somebody to fall back on pipe fitting 9 tops general be 0～5 to spend perpendicular to the angle between the straight line on ground, also can adopt the shape that leans forward slightly as shown in Fig. 7, Fig. 8, this moment, usually 5～20 degree (be something or somebody to fall back on pipe fitting 9 tops be perpendicular to the angle between the straight line on ground 5～20 spend) leaned forward on the top of something or somebody to fall back on pipe fitting 9, its effect is that sofa is when opening, toward leaning forward, user's head is more comfortable more for something or somebody to fall back on.
Present embodiment also can be provided with lining 12, and lining 12 is embedded in 17 li in pilot hole 18 or something or somebody to fall back on pipe fitting hole, and something or somebody to fall back on pipe fitting 9 passes lining 12.
As shown in Figure 3, Figure 4, this something or somebody to fall back on backrest jockey with by wall sofa brandreth when being connected, bottom linker 1 is fixedlyed connected with bottom linkage rod 14, backrest 8 is fixedlyed connected with back bracket 15.
When brandreth is opened (sofa is in extended configuration), promptly from Fig. 3 position to Fig. 5 position, back bracket 15 produces downward forward motion with respect to bottom linkage rod 14, back bracket 15 drive backrests 8 are connected support 6 and move downward forward with backrest, bottom linker 1 drives by the first rotating shaft A and drives connector 2 motions, rotate around the 4th rotating shaft D by second rotating shaft B drive stopping connector 4 and drive connector 2, stop connector 4 and contact back drive lifting connector 3 with confined planes 2 32 around the rotation of the 4th rotating shaft D by spacing pin 5, lifting connector 3 drives 7 motions of pipe fitting support by the 3rd rotating shaft C, thereby make pipe fitting support 7 drive something or somebody to fall back on pipe fitting 9 and produce moving of rising, so something or somebody to fall back on 16 moves upward along lining 12.
Among the utility model embodiment, stablize connecting rod 10 and make that both sides were stable more, synchronous when something or somebody to fall back on rose, top connecting plate 11 is for the ease of mounting bush 12, and lining 12 is to be more smooth and easy for something or somebody to fall back on pipe fitting 9 rises, reduce friction and noise, do not have lining 12, something or somebody to fall back on pipe fitting 9 also can be directly moves along the pilot hole 18 on backrest 8 tops, something or somebody to fall back on mounting bracket 13 1 is in order to gain in strength, the 2nd, and for the ease of the yoke of something or somebody to fall back on 16 is installed.
It is waist shape lifting connector groove 30 on spacing pin 5 and the lifting connector 3 that crucial part is arranged among the utility model embodiment, and its purpose is when preventing that brandreth from drawing in, and something or somebody to fall back on 16 produces injury effect in the decline process.When brandreth is opened, stopping connector 4 contacts by the confined planes 2 32 of spacing pin 5 with lifting connector groove 30, drive 3 motions of lifting connector, thereby something or somebody to fall back on pipe fitting 9 is risen, reach the purpose of something or somebody to fall back on 16 liftings, when brandreth draws in, under something or somebody to fall back on 16 unencumbered situations, something or somebody to fall back on 16 relies on self gravitation to descend, and when something or somebody to fall back on 16 has obstruction, stops connector 4 to contact by the confined planes 1 of spacing pin 5 with lifting connector groove 30, thereby driving something or somebody to fall back on 16 descends, and have certain safe distance between something or somebody to fall back on 16 and the backrest 8 this moment, prevents accident such as crush, as shown in Figure 6.
The simple deformation of the utility model technical characterictic or technical scheme and combination should be thought to fall into protection domain of the present utility model.
