SOFA LINKAGE SUPPORT APPARATUS

WIPO Patent Application WO/2020/177542

A1

A sofa linkage support apparatus comprises a base (1), a driving mechanism (6), a sliding mechanism (2), a first linkage rod (22), a second linkage rod (23), and two retractable supports (3) provided on the base (1). One end of a slide rail (21) is connected to the first linkage rod (22), and the other end of the slide rail (21) is suspended. A slider (24) is mounted on the slide rail (21), and is slidable along the slide rail (21). Two ends of the first linkage rod (22) and two ends of the second linkage rod (23) are respectively connected to two retractable mechanisms. The second linkage rod (23) is connected to the slide rail (21) by means of the slider (24). The driving mechanism (6) comprises a driving motor (61) and a lead screw (62). The lead screw (62) is provided in the slide rail (21). The driving motor (61) is used to drive the lead screw (62) to rotate. The lead screw (62) is used to drive the slider (24) to reciprocate along the slide rail (21). The slider (24) drives, by means of the first linkage rod (22) and the second linkage rod (23), the two retractable supports (3) to extend or retract. The apparatus has a simple structure and high precision, ensures that a sofa moves smoothly and produces less noise during a change of configuration, and eliminates sudden changes and shaking of the sofa.
