ROCKING CHAIR FRAME AND ROCKING CHAIR
Document Type and Number:
WIPO Patent Application WO/2024/055363
Kind Code:
A1
Abstract:
A foldable rocking chair frame, comprising a center cross assembly (1), two sets of support assemblies (2), two turning rods (3), and two sets of linkage assemblies (4). The two support assemblies (2) are connected by means of the center cross assembly (1); one end of each turning rod (3) is connected to one support assembly (2) and can rotate at the position where the turning rod (3) is connected to the support assembly (2); each linkage assembly (4) has one end connected to one turning rod (3), and the other end connected to the center cross assembly (1) or one support assembly (2); the linkage assemblies (4) can move along with the rotation of the turning rods (3), and the movement of the linkage assemblies (4) can change the distance between the two support assemblies (2). A linkage mechanism composed of multiple linkages (401) and the turning rods (3) is used, single-sided limiting of the turning rods (3) is ingeniously used, and the difference between two ends of the center cross assembly (1) is changed by using the lever principle and by means of rotation points of turning rods (3) and linkages (401), so as to unfold and fold the frame. By rotating and folding, the height of the entire frame can be reduced by half after folding, thereby reducing the volume after folding.
