DOWNHILL-SLIDING APPARATUS

摘要

A downhill-sliding apparatus comprises a board having an undersurface ada pted to contact the ground during use of the apparatus. An upper surface is opposite the undersurface, and has a longitudinal dimension. A linkage confi guration has a pair of legs separately mounted to the upper surface and is s paced apart along the longitudinal dimension of the board. A link assembly i nterconnects the legs so as to allow relative movement of free ends of the l egs with respect to one another so as to cause a flexion of the board.
