发明名称 Semi-stable balance board toy.
摘要 <p>The present invention facilitates teaching a young child to balance by providing fore-to-aft stability, thus only requiring the child to balance side-to-side over a fulcrum. A semi-stable symmetric fulcrum 8 smoothly extends beneath a flat standing platform 4, blending smoothly from a fulcrum point to horizontal lower surfaces parallel to, and in close proximity with, opposed ends of the standing platform. The fulcrum generally corresponds in width to the width of the standing platform and is substantially flat across this width so that the flat smoothly curving surface over the fulcrum defines a semi-stable rocking surface which facilitates side-to-side motion, yet hinders fore-to-aft motion.</p>
