Abstract

A rotary positioning table is disclosed. The table generally includes a table top and a central support structure, in which the table top can rotate about a point of rotation, typically a rotary bearing, with respect to the central support structure, thus enabling a user to generally be able to stay in the same position while rotating the table top to a desired position. The central support structure generally includes a top frame connected to and generally parallel to the table top, a center frame connected to and generally perpendicular to the top frame and an end frame connected to and generally perpendicular to either side of the center frame, wherein the end frames are generally perpendicular to the top frame. The frames can all be folded generally parallel to a common reference place for ease of transport and storage.

Claims

1. A work table, comprising:

a table top;

a center support structure including;

a top frame connected to and generally parallel to the table top;

a center frame connected to and generally perpendicular to the top frame;

an end frame connected to and generally perpendicular to either side of the center frame, wherein the end frames are generally perpendicular to the top frame; and

wherein the top frame is pivotally connected to the center frame and thus adapted to rotate toward the center frame.

2. The table as claimed in claim 1 further comprising a point of rotation located between the table top and the top frame.

3. The table as claimed in claim 2, wherein the point of rotation is a rotary bearing.

4. The table as claimed in claim 1, wherein the end frames pivotally connected to the center frame and thus are adapted to rotate toward the center frame.

5. The table as claimed in claim 4, wherein the top frame, the center frame and the end frames can be oriented generally parallel to each other in a stored configuration.

6. The work table as claimed in claim 1 further comprising a footer connection.

7. The work table as claimed in claim 6 wherein the footer connection is a caster.

8. The work table as claimed in claim 6 wherein the footer connection is a roller.

9. The work table as claimed in claim 6 wherein the footer connection is a heightening system.

10. The work table as claimed in claim 6 wherein the footer connection is a leveling system.
