ABSTRACT:
A pool table carriage for supporting a pool table at an elevated position above a horizontal support structure, and for transporting the pool table between locations without damaging the pool table. The pool table carriage comprises two support plate assemblies and a main frame interposed therebetween. Each support plate assembly selectively supports one of the legs of the pool table, when the pool table carriage is being deployed. Each support plate assembly further has four selectively extendable rotatable jackscrews, and two wheel assemblies each having wheels. The jackscrews are extendable in two opposite directions. Rotation of the jackscrew in one direction causes the jackscrew to retract upward, thereby allowing the wheels to contact the support structure, thereby allowing the pool table carriage to roll between different locations. Rotation of the jackscrew in the other direction causes the jackscrew to extend downward, thereby raising the wheels above the support structure, thereby immobilizing the pool table carriage.
