  • Patent number: 11274809
    Abstract: A system for lighting a volleyball court has four corner light assemblies, two side center light assemblies, and four mid-court light assemblies. Each corner light assembly has an upper light fixture adapted to emit light outward and downward at a level generally below a player's eye level and a lower light element mounted in a manner to emit light outwards and upwards. Each side center light assembly has two lower light fixtures adapted to emit light outward and downward at a level generally below a player's eye level and an upper light assembly adapted to emit light outwards and upwards at a level generally above a player's eye level. Each mid-court light assembly has a light fixture adapted to emit light outward and downward at a level generally below a player's eye level. By ensuring that no light is emitted at a player's eye level, glare is significantly reduced.

  • Patent number: 8197364
    Abstract: A volleyball training device includes a telescoping vertical member having a height adjustable between a predetermined minimum and maximum height. The telescoping vertical member has a lower end adapted to be mounted in the ground and an upper end. A horizontal member having a first end and a second end is attached to the upper end of the telescoping vertical member adjacent to the first end thereof. A flexible member having a first end and a second end is connected adjacent to the second end of the horizontal member at a first end thereof. A volleyball holder is coupled to the second end of the flexible member and is adapted to securely hold a volleyball in a manner which allows a user to strike a top portion thereof when the volleyball is positioned within the volleyball holder.
