Game table with centrifugal blower assembly
View Patent ↗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.
1. 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.
2. The game table of claim 1 , further comprising a plurality of elongate passageways interposing the plenum box and the flat game surface, the passageways being arranged longitudinally with respect to the flat game surface and laterally with respect to the plenum box.
3. The game table of claim 2 , wherein the holes defined in the flat game surface are arranged in rows, each row in communication with one of the plurality of elongate passageways.
4. The game table of claim 2 , further comprising a plenum chamber interposing the longitudinal passageways and the plenum box for communicating moving air from the plenum box into the longitudinal passageways.
5. The game table of claim 1 , further comprising a blower attached to the air intake proximate the taller end and configured to provide positive air pressure into the plenum box.
6. The game table of claim 5 , wherein the blower is a centrifugal type blower.
7. The game table of claim 1 wherein the flat game surface is substantially rectilinear in shape.
8. The game table of claim 1 , wherein the flat game surface is marked to simulate a hockey arena.
9. The game table of claim 1 , further comprising a plurality of legs configured to stabilize the flat game surface in a substantially horizontal position.
10. 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.
11. The air powered hockey table of claim 10 , wherein the plenum box further comprises a diverter positioned near the side wall opening to divert incoming airflow along a length of the plenum box.
12. The air powered hockey table of claim 10 , further comprising a centrifugal blower attached to the side wall opening and configured to provide airflow into the plenum box.
13. The air powered hockey table of claim 12 , further comprising a power circuit for selectively powering the blower.
14. The air powered hockey table of claim 10 , wherein the flat playing surface is marked and sized to approximate a scaled-down hockey arena.
15. The air powered hockey table of claim 10 , further comprising side walls, end walls, and corner members bounding the flat playing surface.
16. The air powered hockey table of claim 15 , further comprising a puck return tray in each of the end walls.
17. The air powered hockey table of claim 10 , further comprising a plurality of legs adapted to support the flat playing surface in a substantially horizontal position.
18. 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, the flat playing surface being marked and sized to approximate a scaled-down hockey arena;
side walls, end walls, and corner members bounding the flat playing surface;
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;
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; and
a blower;
wherein the plenum box comprises first and second end walls, two side surfaces, a bottom surface, and an internal diverter, the two end walls being of first and second height, respectively, wherein the second height is greater than the first height;
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 the blower; and
wherein the blower is configured to provide air into the plenum box under positive pressure.
19. The air powered hockey table of claim 18 , wherein the blower is a centrifugal blower.
20. The air powered hockey table of claim 18 , wherein the blower is selectively powerable.
