Document Type and Number:
WIPO Patent Application WO/2020/232793
Kind Code:
A1
Abstract:
The present invention relates to a dissembleable chair base and a chair. The chair base comprises support legs and a central support member. The central support member comprises a support main body and multiple installation portions. The support legs are provided with installation recesses at one side thereof. The installation portions are embedded within the installation recesses in a transverse direction. Secure fastening assemblies are provided between the support legs and the central support member as so to prevent the installation portions separating from the installation recesses in the transverse direction. The installation portions are provided with first position limiting portions, and the support legs are provided with second position limiting portions. One or more of the first position limiting portions are located at an outer side of the second position limiting portions in a longitudinal direction, and the first position limiting portions engage with the second position limiting portions to form longitudinal position limiting structures preventing the support legs separating from the installation portions in the longitudinal direction. The present invention has a simple structure, is easy to disassemble, and saves transportation costs. The support legs are securely connected to the central support member, and fastening and position limiting structures are adopted in both the transverse and longitudinal directions, thereby reducing the likelihood of loosening and wobbling. An engagement between a sliding channel and a guide portion enables precise installation of the second position limiting portions at corresponding positions, thereby reducing difficulties in installing the support legs.
