Design manual of chess and card table

Abstract

This board table in the design process, the chessboard uses parallelogram mechanism to make the three-prism synchronous rotation scheme. Using this scheme to achieve three kinds of chessboard transformation (Go, Chinese chess, chess). In the foldable table leg part, a four-bar mechanism is adopted, and the static point in the four-bar mechanism is used to realize the expansion and stable support of the table. The stop mechanism is also used in the design of folding stool. This design is integrated, reducing the overall folding volume to 34% of the unfolding volume.
