发明名称 Playground apparatus
摘要 A playground apparatus for one or two occupants having an elongated member mounted for 360 DEG rotation about a horizontal shaft in a support frame. A seat for the occupant is mounted at one end of the rotating member allowing the occupant to remain upright during rotation of the elongated member. Where the device is intended for use by a single occupant, the weight of the single occupant is counterbalanced by a variable weight at the opposite end of the rotating elongated member with the occupant propelling the device by pushing of the surface on which the apparatus rests with the legs. Where the device is intended for use by two occupants, there is a seat at each end of the elongated member.
