Abstract
A vertical aerial assembly for the volleyball includes a lower fixing rod, a lower screw member, an aerial, a handle, an upper screw member, and an upper fixing rod. The vertical aerial assembly has a simplified construction with fewer parts, thereby decreasing the cost of fabrication. In addition, the vertical aerial assembly is assembled easily and conveniently, thereby saving the time of assembly. Further, the handle only needs to form a through hole to fit the outer diameter of the aerial without having to additionally provide a stepped hole, thereby decreasing the cost of fabrication.
