Abstract
A game table is disclosed. The table includes a flat game surface having a plurality of air holes defined therein and a plenum box having a tapered profile proceeding from a shorter end to a taller end. There may be a plurality of elongate passageways between the plenum box and the flat playing surface, the passageways being arranged longitudinally with respect to the flat game surface and laterally with respect to the plenum box.
Claims20
A game table comprising:
- a flat game surface having a plurality of air holes defined therein;
- and
- a plenum box having a tapered profile proceeding from a shorter end to a taller end, an air intake proximate the taller end, and an internal diverter configured to at least partially redirect airflow from the taller end to the shorter end;
- wherein the plenum box communicates with the flat game surface to provide substantially equal air flow through the plurality of air holes.

An air powered hockey table comprising:
- a flat playing surface defining a plurality of substantially evenly spaced holes therein sized to permit airflow therethrough to provide air cushioning of a game puck;
- a plurality of longitudinal air passage ways connecting to the flat playing surface on a bottom side and arranged to convey air to the air holes;
- and
- a plenum box arranged laterally across the longitudinal air passage ways and configured to convey air under positive pressure into the plurality of longitudinal air passage ways;
- wherein the plenum box comprises first and second end walls, two side surfaces, and a bottom surface, the two end walls being of first and second height, respectively, wherein the second height is greater than the first height;
- and
- wherein at least one of the two side surfaces has a side wall opening proximate the second end wall and sized to receive output from a blower.
