Claim:
A foldable lap table, folding from an unfolded to a folded position comprising: a first table leaf joined along a first hinge to a second table leaf, the first hinge folding in a first direction, from the unfolded position; a third table leaf joined along a second hinge to a fourth table leaf, the second hinge being a linear extension of the first hinge, in the unfolded position, and the second hinge folding in a second direction opposite the first direction, from the unfolded position; the third table leaf further joined to the first table leaf along a third hinge, the third hinge forming a first acute angle with the second hinge in the unfolded position and a first obtuse angle with the first hinge in the unfolded position; the fourth table leaf further joined to the second table leaf along a fourth hinge, the fourth hinge forming a second acute angle with the second hinge in the unfolded position and a second obtuse angle with the first hinge in the unfolded position; and wherein, the respective hinges and leaves are arranged to permit unison movement of the leaves when the lap table is folded and unfolded such that as the lap table is folded by movement of any one leaf, the first leaf and the second leaf rotate towards one another about the first hinge, the third leaf and the first leaf rotate towards one another about the third hinge, the fourth leaf and the second leaf rotate towards one another about the fourth hinge, and the third leaf and the fourth leaf rotate towards one another about the second hinge.
