ABSTRACT:
The present device is an improved table for attachment to the frame of a chair. The improved table comprises, in general, a table top including a first table top half and a second table top half; cooperative holding devices for holding the table halves together to establish a unitary condition of the table top; a first crank for rotatably supporting the first table top half for rotation about a first substantially vertical axis; a first mounting tube for rotatably supporting the first crank for rotation about a second substantially vertical axis offset from the first vertical axis, a first bracket for attaching the first mounting tube to the frame of the chair; a second crank for rotatably supporting the second table top half for rotation about a third substantially vertical axis; a second mounting tube for rotatably supporting the second crank for rotation about a fourth substantially vertical axis offset horizontally from the third vertical axis, and a second bracket for attaching the second mounting tube to the frame of the chair. The dimensions of the components of the table and the distances between certain pivot axes can be selected so that parallel movement of the table top can be accomplished. However, if the dimensions of the chair are such that will not permit the above mentioned dimensions to be selected, under certain conditions the table top may be moved from a forward most position to a rearward most parallel position by skewing the table top as it is moved.
