The connection point of the leg linkage 14 and the mounting side plate 12 is located in the opening direction of the linkage limiting member 11, so as to avoid the interference between the leg linkage 14 and the linkage limiting member 11 when rotating. Be provided with on the installation curb plate and be used for carrying out spacing limit structure to the linkage locating part, extend extreme position when shank subassembly, linkage locating part is contradicted with limit structure.
The embodiment also provides a sofa support, specifically, the sofa linkage device further comprises a backrest 4, and the backrest 4 is hinged to one end of the seat frame mounting frame 2 far away from the leg component 3. The backrest part 4 is hinged on the seat frame mounting frame 2, the middle part of the backrest part 4 is rotatably connected with the backrest connecting piece 13, and the backrest part 4 is used for connecting and adjusting the seat backrest. During extension or retraction of the linkage assembly, the back member 4 can rotate about the seat frame mounting 2 to adjust the seat back angle. The hinge point of the backrest part 4 and the seat frame mounting frame 2 does not change relative position with the seat frame mounting frame 2 in the rotation process of the backrest part. The backrest member of the present embodiment can be used to mount a conventional rectangular backrest and also can be used to mount a T-shaped backrest structure having two wings. The narrow end of the T-shaped backrest is connected with the backrest piece, and the two-wing structure with the large width can rotate around the seat armrest under the driving of the backrest piece 4.
Specifically, the inner side wall of the seat frame mounting frame 2 is provided with a mounting platform 21, the height of the mounting platform 21 is lower than the upper edge of the seat frame mounting frame 2, and the plane where the mounting platform 21 is located is the seat frame mounting surface 211. It should be noted that, a plurality of mounting platforms 21 may be provided, in this embodiment, the mounting platform 21 is a bending portion formed by bending the lower edge of the seat frame mounting bracket 2 inward, four mounting platforms 21 are provided along the length direction of the seat frame mounting bracket 2, and the seat frame may be fixedly mounted on the mounting platform 21 by a fastening member such as a bolt, a nut, or a rivet. This application mounting platform 21 highly reduces for the seat frame can sink the installation, increases the seat deeply, highly unchangeable at the sofa, under the condition that seat frame installation face 211 reduces, can also make the highly increase of seat stabilizer blade, and seat frame lower part space strengthens, and on the other hand also can make the soft packet of thickness of sofa cushion increase, improve the comfort level.
Specifically, when the sofa support is retracted to the extreme position, the distance H1 between the highest point of the seat frame mounting bracket 2 on the seat frame mounting surface 20 and the lowest point of the leg assembly 3 in the vertical direction is not greater than 170 mm. Preferably, it may be 170mm, 160mm, 155mm or 150 mm. The smaller the distance H1, the thinner the sofa legs compress after collapsing, and the less space it takes up in the vertical direction. When the sofa support 10 is contracted to the extreme position, the distance H2 between the highest point of the seat frame mounting bracket 2 on the seat frame mounting surface 211 and the highest point of the footrest mounting surface 321 in the vertical direction is not more than 50 mm. Preferably, the distance H2 between the highest point of the seat frame mounting bracket 2 on the seat frame mounting surface 211 and the highest point of the footrest mounting surface 321 in the vertical direction may be 50mm, 45mm or 40 mm. The smaller the distance H2, the smaller the thickness of the sofa front when the leg assembly 3 is collapsed.
In particular, the height difference H between the footrest mounting surface 321 and the highest point of the backrest part 4 when the leg assembly 3 is extended to the extreme position is not less than 80mm, preferably 80mm, 90mm, 150mm or 200 mm. Compare in traditional structure, the structure of leg portion interlock piece 14 and linkage locating part 11 makes seat leg portion subassembly extend highly to increase in this embodiment linkage subassembly, and leg portion subassembly 3 drives the inclination increase of seat frame mounting bracket 2, has increased the seat comfort level after the sofa support expandes.
