The present invention provides a mobile folding table with attached seating having an improved lift-assist mechanism. In particular, the table includes a gas cylinder that provides a force tending to extend the cylinder to assist in folding the table into a storage position, the cylinder providing substantially no force to resist rapid extension thereof. Preferably, a mobile folding table according to the present invention also includes a stabilizing mechanism including center bench legs attached to a center leg structure that is maintained substantially upright whether the table is in an unfolded use configuration, in a mobile folded storage configuration, or in the process of being folded or unfolded. In this manner, the attached benches are prevented from freely tipping when the table is being folded or moved.

1. A mobile folding table adapted for assisted transition between an open position and a closed position, said table comprising: a first table section pivotally connected to a second table section to permit folding and unfolding the table about a substantially horizontal pivotal axis between an open position and a closed position, wherein said first and second table sections are substantially horizontal in the open position, and wherein said first and second table sections are substantially vertical in the closed position;a high-speed cylinder assembly having a top member and a bottom member slidably connected to the top member for movement of the members between contracted and extended positions, the top member having a top end attached to the table proximate to the pivotal axis; anda linkage assembly comprising a first side link having a top end rotatably connected to the first table section about a first side axis substantially parallel to the pivotal axis, a second side link having a top end rotatably connected to the second table section about a second side axis substantially parallel to the pivotal axis, and a base fixedly connected to a bottom end of the bottom member of the cylinder assembly, wherein the first and second side links each have a bottom end rotatably connected to the base about a bottom axis substantially parallel to the pivotal axis, andwherein the base is located substantially vertically below the pivotal axis;wherein the cylinder assembly contains compressed fluid adapted to produce a force tending to move its members apart from each other to extend the assembly toward the extended position, wherein extending the cylinder assembly toward the extended position causes the table sections to fold together toward the closed position, andwherein the cylinder assembly produces substantially no force to oppose rapid extension of the assembly,further comprising a first bench and a first bench leg, the first bench being configured for rotational movement to remain generally parallel to the first table section as the table is folded between the open and closed positions, the first bench being pivotally and slidably connected to a top end of the first bench leg, and a bottom end of the first bench leg being fixedly attached to the base to at least substantially prevent the first bench from pivoting when the table sections are stationary. 2. The table of claim 1, further comprising a second bench and a second bench leg, the second bench being configured for rotational movement to remain generally parallel to the second table section as the table is folded between the open and closed positions, the second bench being pivotally and slidably connected to a top end of the second bench leg, and a bottom end of the second bench leg being fixedly attached to the base to at least substantially prevent the second bench from pivoting when the table sections are stationary. 3. A mobile folding table adapted for assisted transition between an open position and a closed position, said table comprising: a first table section pivotally connected to a second table section to permit folding and unfolding the table about a substantially horizontal pivotal axis between an open position and a closed position, wherein said first and second table sections are substantially horizontal in the open position, and wherein said first and second table sections are substantially vertical in the closed position;a high-speed cylinder assembly having a top member and a bottom member slidably connected to the top member for movement of the members between contracted and extended positions, the top member having a top end attached to the table proximate to the pivotal axis; anda linkage assembly comprising a first side link having a top end rotatably connected to the first table section about a first side axis substantially parallel to the pivotal axis, a second side link having a top end rotatably connected to the second table section about a second side axis substantially parallel to the pivotal axis, and a base fixedly connected to a bottom end of the bottom member of the cylinder assembly, wherein the first and second side links each have a bottom end rotatably connected to the base about a bottom axis substantially parallel to the pivotal axis, andwherein the base is located substantially vertically below the pivotal axis;wherein the cylinder assembly contains compressed fluid adapted to produce a force tending to move its members apart from each other to extend the assembly toward the extended position, wherein extending the cylinder assembly toward the extended position causes the table sections to fold together toward the closed position,wherein the cylinder assembly produces substantially no force to oppose rapid extension of the assembly, andwherein the high-speed cylinder assembly is housed in a telescoping tube assembly, the telescoping tube assembly comprising an upper tube attached to the table proximate to the pivotal axis and a lower tube slidably connected to the upper tube and fixedly connected to the base.
