发明名称 Portable protective cage for athletic equipment
摘要 Portable cage-like protective apparatus for surrounding athletic field equipment such as pad assemblies for high jump and pole vault landing pits, as protection against mischievous damage to such pad assemblies, making it unnecessary to disassemble and move the pad assemblies or other athletic field equipment daily. Vertical wall panels and horizontal top panels of the apparatus have pipe frames covered with fencing wire cloth such as chain link fencing. Removable wheels provide portability when needed, and a movable wall facilitates movement of the protective cage apparatus into and out of a protective position surrounding jump and vault pit pad assemblies. Truss assemblies extending upward above the cage panels provide stiffening and support, while the total weight of the apparatus is kept low. Disassembly of the apparatus for storage in a compact form is facilitated by the use of simple clamps to interconnect panels to one another.
