Abstract: A mobile frame assembly includes a trailer assembly having a trailer body, a draw assembly and wheels. The mobile frame assembly includes a base assembly, an intermediate assembly and an upper assembly each having at least two primary rails. Lower support risers are coupled to the base assembly primary rails and extend to the intermediate assembly primary rails forming a lower frame assembly. Upper support risers are coupled to the intermediate assembly primary rails and extend at least to the upper assembly primary rails. A platform assembly including a launch platform, a landing platform and a safety pit positioned therebetween is disposed at least partially within the lower frame assembly. An obstacle assembly is disposed generally within the mobile frame assembly over the safety pit, wherein at least some of the upper support risers are telescoping members operable to expand the distance between the obstacle and the safety pit.

Abstract: A versatile frame assembly includes a lower frame assembly and an upper frame assembly. The lower frame assembly includes a base assembly having primary rails and cross rails that are coupled together, an intermediate assembly having primary rails and cross rails that are coupled together and lower support risers coupled between the base assembly primary rails and the intermediate assembly primary rails. The upper frame assembly includes the intermediate frame assembly, an upper assembly having primary rails and cross rails that are coupled together and upper support risers coupled between the intermediate assembly primary rails and the upper assembly primary rails. A platform assembly including a launch platform, a landing platform and a safety pit positioned therebetween is disposed generally within the lower frame assembly. At least one obstacle assembly is disposed generally within the upper frame assembly over the safety pit.
