Today’s Patent – Foldable Chair

The said invention (US12127686B2) was invented by Libin Chen, Qinglei Kong, patented by USPTO on 27-11-2021. Currently, it stands assigned to Individual.

The present invention relates to the technical field of chairs, and in particular to a folding chair. Foldable chairs are popular due to their space-saving feature after being folded. Compared with ordinary folding chairs, the structure of folding rocking chairs is more complicated, and the prior products are able to achieve folding and unfolding.

After being unfolded, the folding chair is usually locked by a locking mechanism to prevent it from being folded during use. However, the locking mechanism is prone to locking failure, which causes the folding chair to be unstable in use, leading to potential safety hazards. For this reason, it is necessary to manually check whether the locking mechanism is working properly. In addition, to fold the folding chair, the locking mechanism must be released. Thus, the processes of unfolding and folding of the folding chair are cumbersome.

The folding chair includes two mirror-symmetric slant support mechanisms and a linkage mechanism connected between the two slant support mechanisms, where the slant support mechanisms each include two slant support posts and two bottom frame posts; the linkage mechanism includes two linkage posts that cross each other and are hinged; upper ends of the two slant support posts and an upper end of a linkage post are hinged to a first connecting member; first ends of the two bottom frame posts are respectively hinged to the two slant support posts, and second ends of the two bottom frame posts are hinged; lower ends of the two linkage posts are respectively connected to the two slant support mechanisms; the folding chair further includes a pressing mechanism and a cushion.
