专利汇可以提供Playground jumping device专利检索,专利查询,专利分析的服务。并且The device includes a fixed vertical base pipe and a capped vehicle pipe telescoping thereover. Two axially aligned compression springs mounted within the telescoping pipes consist of an upper light spring and a lower heavy spring. A downstop pipe is mounted within the springs and has a fixed member separating the springs attached thereto. The downstop pipe has a length exceeding the combined length of the springs when closed and serves to limit the compression of the light spring. Upon engagement of the top of the downstop pipe with a cap on the upper end of the vehicle pipe further downward movement of the vehicle pipe causes compression of only the heavy lower spring which in turn is limited by engagement of the bottom of the downstop pipe with the top of the base pipe.,下面是Playground jumping device专利的具体信息内容。
