ABSTRACT:
An improved rotational mechanism, or roller assembly, including a central roof support, for use with a rotational building that is characterized by a movable vertical wall. The improved rotational mechanism was designed to prevent binding during rotation of the building, and to prevent or minimize lateral movement and tipping. The rotational mechanism comprises in part an angled member having a vertical leg and a horizontal leg, said horizontal leg projecting inwardly and mounted internally about the lower edge of the building wall. Cooperating with the angled member is an L-shaped angle member, where a radially projecting leg thereof includes at least one ball/transfer caster, preferably a plurality about the building foundation. In operation, the ball/transfer caster is in rolling contact with one horizontally disposed leg of the U-shaped channel. A comparable, laterally directed ball/transfer caster or conventional roller may also be incorporated into the mechanism. By incorporating the central roof support, one can relieve certain of the weight on the ball/transfer caster.
