Abstract: Mobile folding restaurant booth style benches are provided, which may be arranged in opposed pairs to form restaurant style booths. An individual bench incorporates a mechanism for shifting the weight of the bench between a mobile base, which may be supported by swivel casters, and a stationary base, which may be supported by non-slip feet, actuated by pivoting a bench seat down from a folded storage position to an unfolded seating position. The weight shifting mechanism may include an engagement member, which is initially spaced apart from an actuator at a folded angle of the seat, and which contacts and begins transmitting force and movement to the actuator at a partially unfolded angle of the seat.

Abstract: The present invention provides a mobile folding choral riser having lift-assist and stability mechanisms. In particular, the choral riser includes a gas cylinder that provides a force tending to extend the cylinder to assist in folding the riser into a storage position, the cylinder providing substantially no force to resist rapid extension thereof. In addition, the choral riser preferably includes a back railing linkage that permits independent raising and lowering of a back railing member when the choral riser is in a use or partially folded position but constrains the back railing member to a raised position when the choral riser is in an at least substantially fully folded position.

Abstract: 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.

Abstract: In one aspect, an improved locking mechanism for a mobile folding table is provided, permitting convenient access near the top of the folded table to a manual actuator for unlocking the table from a folded configuration. In another aspect, an improved lift-assisting mechanism for a mobile folding table is provided, with a clutch that engages the lift-assisting mechanism only when the table top halves are at an angle from the vertical that is equal to or larger than a predetermined angle. These two aspects may be advantageously and synergistically combined in the same mobile folding table.
