摘要： An improved structure and method of assembly for an exercise wheel of the type described in my U.S. Pat. No. 3,649,007 includes an upper circular support surface conformed to mate with a lower support surface at the periphery, the peripheral edges of the upper and lower surfaces being provided with peripherally overhanging lips dimensioned to be engaged by a semicircular vinyl extrusion which includes interior keying projection for joining the surfaces together. Integral with the surfaces are a plurality of radial ribs, each surface including such ribs in corresponding opposed locations, which upon assembly are aligned relative each other. Formed centrally on the underside of the lower surface is a flange boss to which a pipe flange is secured engaging one end of a pipe supporting a post about which the wheel rotates.
