  • Patent number: 6503177
    Abstract: A pogo stick has an upper tubular member with a hand graspable means on an upper end and a foot engageable means on a lower end, and a lower slider member with a top end and a bottom end, the top end being shaped to telescopically engage the lower end of the upper tubular member, and the bottom end having a removable bumper having a co-molded rubber portion. The lower slider member slides between a retracted position and an extended position, and the upper tubular member includes a spring assembly for biasing the lower slider member towards the extended position. The pogo stick includes a spring assembly that includes springs of varying strengths which, in conjunction with a compression assembly that pre-compresses the spring assembly, enables the user to customize the desired spring characteristics. The hand graspable means includes a novel pair of laterally extending hand grips that can be attached to the upper tubular member with a clamping mechanism supported by an inner lip.
