发明名称 Elevation platform
摘要 A treestand platform is strung in a manner at least similar to the stringing of a sports racket, such as a tennis racket, and a treestand having such a platform. The platform might comprise a peripheral frame supporting and delimiting a tension surface formed by a plurality of crossed string sections. The strung surface may be sufficiently resilient to yield very slightly under load, but is sufficiently tenacious that such slight yielding occurs without breakage or permanent deformation. The stringing provides a platform that is both strong and lightweight. The stringing also provides a platform that has a downward visibility comparable to transparency, and which is substantially noiseless during treestand transport, assembly, erection and use, and any other handling.
