发明名称 Foldable round bouncer/walker
摘要 A play seat includes telescoping scissor frames for supporting a seat above a base ring composed of two opposing arcuate ring sections whose opposite ends are connected together by stiff coil springs. The lower ends of the scissor frames are pivotally connected to the ring sections so that any weight in the seat tends to spread apart the ring sections thereby tensioning the springs whereby the seat is resiliently supported above the ground. Each spring is protectively enclosed within a plastic sleeve.
