ABSTRACT:
An apparatus and method for leveling a playing surface, the apparatus preferably comprising an externally-threaded support rod, a collar threaded upon the support rod, a support surface or member upon which the playing surface rests, and a fastener securing the apparatus to an underlying surface. In one preferred embodiment, the support surface or member is part of the collar, and the threaded rod is fitted with a foot which rests upon the underlying surface. By turning the threaded rod with respect to the collar, the collar is moved up or down the support rod, thereby lifting or lowering the playing surface. In another preferred embodiment, the support surface or member is an annular element secured on the support rod against axial movement along the support rod, the collar being rigidly secured to the underlying surface. By turning the support rod with respect to the collar, the support rod is threaded out of or into the underlying surface, thereby lifting or lowering the playing surface. Access to the support rod is preferably made via an aperture in the playing surface into which the top of the support rod extends. The top of the support rod is preferably shaped to accept a tool inserted through the aperture in the playing surface for turning the support rod and adjusting the support level of the apparatus. Preferably, the apparatus is fastened to the underlying surface by a fastener passed through an axial aperture in the support rod and into the underlying surface.
