  • Patent number: 5746660
    Abstract: A tilt and roll support for pool tables and other game tables having a frame attached to the underside of the table. The opposite ends of the frame have pivot shafts which are axially aligned with the longitudinal axis of the table. Support assemblies at the ends of the table are pivotally about the pivot shafts so the table may be rotated between a vertical stored position and a horizontal use position. The lower portion of the support assemblies are retractable against the bottom of the table for storage and may be extended to a vertical position. The lower portion of the support assemblies are on rollers or casters and are extendible so the weight of the table may be transferred to the tilt and roll supports for movement and storage. When the table is in use, the table is supported on conventional legs.

  • Patent number: 3988021
    Abstract: A game table is disclosed having a support structure including leg assemblies at either end supporting the table. The leg assemblies include a first member pivotally attached to the table along the longitudinal axis of the table and a second member pivotally attached to the first and to a caster pedestal. The pedestals are interconnected by an adjustable rod which can be extended and retracted to level, raise and lower the table. Adjustable braces extend between the tabletop and the pedestals. The tabletop can be pivoted to a generally vertical position thereby facilitating movement and storage of the table when not in use.
