发明名称 PLAYING TABLE WITH BASE FOR HOLDING FLUID THEREIN
摘要 There is disclosed herein a playing table for games, such as billiards or the like, generally employing a playing board and a base wherein fluid in the base is utilized for distributing the supporting force to the board in a uniform manner and providing substantially all of the supporting force therefor. A float device may underlie substantially the entire board and float upon a liquid within the base, or the support and uniform distribution of the board may be provided by a bladder type device. Additionally, the uniform support and force distribution arrangement permits use of board materials not otherwise generally considered usable for providing a flat playing surface, such as a slab of concrete. A nut arrangement attached to the board provides for clamping of the board to the base in a substantially fixed relationship for maintaining the plane of the board substantially fixed.
