Definitions

• the present invention relates to a folding table with associated seat structures and more particularly to a non-rectangular table, folding between a use position and a storage position with benches spaced around the table.
• This furniture includes tables, chairs, benches and/or stools and combination table and seating units.
• Such furniture provides added utility if it is folding, so as to minimize the storage space needed.
• Folding tables and associated stools or bench units are well known and provide seating and table space that requires a relatively small area for storage as compared to the space needed during use.
• Such folding tables are generally rectangular, folding along a center line, and have benches or stools placed along both sides of the table, but no seats at the ends. Although such tables are successful in providing folding furniture with seating along either side, still further improvements are possible.
• seating provided in a somewhat circular arrangement rather than in a linear arrangement.
• Such an arrangement provides for balanced distribution of the occupants and may facilitate easier access to the center of the table among the occupants.
• Such an arrangement may have dimensions that also fit better into some areas and may provide for added seating in a given space.
• folding oval table and seating units have been developed. Examples of such table and seating units are shown in U.S. Patent Nos. 6,065,802; 6,254,178; and 6,386,628, all to Bue and assigned to Sico, Inc., the Assignee of the present invention.
• the oval folding table and seating units have proven to be very successful in providing a seating and table space that has occupants seated around an oval table and substantially evenly spaced around the table.
• the table and seating units fold and have a relatively low ratio of the storage space needed per seat.
• additional seating may be required.
• combination table and seating structures may utilize benches.
• benches may increase the seating capacity, problems with actuation, support and access are encountered when benches are utilized in a folding table and seating system. As elements fold and are spaced further apart, it is difficult to support both ends of a bench which spans supports with the distance between the supports changing during folding and unfolding. To overcome this, some systems have been developed to shorten the bench while this decreases the seating capacity.
• Other systems utilize sliding supports that increase the complexity of building and may potentially jam during the folding process. Still others span areas wherein the access to the bench is substantially blocked by supporting framework and might cause a tripping hazard.
• the frames of such table and seating assemblies must be configured differently when supporting stools as compared to being configured for supporting benches, increasing complexity.
• a new and improved table and seating structure is needed.
• Such a table and seating structure should provide non-rectangular table with seating spaced around the table.
• the table should allow for the use of benches for increased seating capacity.
• Such a table and seating system provides added utility if benches and stools may be interchangeably used with the same support frame.
• the table and seating system should provide for easy folding and improved access to the benches and should fold to a storage position requiring less storage space. The present invention addresses these, as well as other problems associated with folding table and seating systems. Summary of the Invention
• the present invention is directed to a folding table and seating apparatus and in particular to a non-rectangular folding table and seating structure.
• the tabletop includes a pair of, for example, semicircular shaped tabletop sections folding along a straight edge of each section.
• a lock maintains the table in the unfolded position and is easily released by accessing an end handle that extends downward from the center axis near the edges of the tabletop sections.
• the framework extends downward and out to interchangeable seating configurations. In a first configuration, the framework extends downward and out to eight stools, four stools spaced apart around the periphery of each tabletop section. A wheel or a leg extends downward below each stool to provide spaced apart supports around the entire table.
• the framework extends from under each stool inward toward the tabletop to provide easy access for a person to be seated at the stools without impeding their access or seated comfort.
• the stools are replaced with curving benches.
• Two curving benches are associated with tabletop section.
• the benches fold from a horizontal use position to a substantially vertical storage position.
• the benches curve around the periphery of the tabletop sections with space for walking between the benches at each end.
• the benches increase seating capacity from eight to up to twelve people, particularly when used for seating children.
• the benches are pivotally mounted at the top of the seat framework supports to allow for folding between the use position and storage position.
• the distance between the pivot points for the benches and the tabletops and the two corresponding pivot points of each tabletop section are the same so that the table and seating assembly folds with each half of the assembly functioning as a four bar linkage in a parallelogram type configuration.
• the benches pivot, but the configuration and spacing of the pivot points eliminates the need for sliding relative to the framework.
• the folding framework folds the tabletops from a horizontal position to a vertical position wherein the bottoms of the tabletops substantially oppose one another.
• the stools fold inward with the seats remaining substantially horizontal in a configuration that reduces the floor space occupied by the assembly in the unfolded use position.
• the benches also wrap around the edges of the table so that the table requires less floor space than in the unfolded use position.
• the table and seating structures are supported on four wheels so that the assembly may be rolled to any desired location.
• a lock holds the table in the folded position for easy and safe movement.

• the table and seating structure includes a pair of opposed table top sections 14 with a folding supporting frame 12. Eight stools 16 are spaced around the periphery of the table, four stools 16 about each table top section 14, and provide for seating proximate the edge of the tabletops. The stools 16 are substantially evenly spaced apart so that eight users may sit at the table without infringing upon one another's space.
• the table and seating structure 10 includes a folding mechanism 18 that folds the table between the use position shown in FIG. 1, and the folded storage position, shown in FIG. 2.
• the seat tops of the stools 16 remain substantially horizontal while the table tops 14 fold to a vertically extending position with the bottom surfaces substantially facing one another.
• the table and seating structure 10 is supported on support legs 22 below four of the stools 16 and on casters or wheels 20 below the other four stools 16.
• the table and seating structure 10 is supported on the four swiveling wheels 20, so that the table and seating structure 10 may be rolled to any desired location.
• the folding mechanism 18 includes a latch to lock the table and seating structure 10 in the unfolded use position.
• the latch has a lock member 50 that extends along the center line of the folding mechanism 18 and under the table tops 14 to near the edges so that it is hidden from above, yet is easily releasable by lifting a handle 52 from engaging a stop member, to fold the table and seating structure 10.
• the frame 12 includes risers 32 extending out from pivots 48 underneath the semi-circular table top members 14.
• the table tops 14 have arcing outer edges that form an oval, shown as a circle. It is also envisioned that other non-rectangular shapes, such as octagons or other polygons could be used, preferably a configuration with adjacent stools 16 centered on the nearest straight section or arcing edge, and substantially evenly spaced about the periphery of the table 10.
• the risers 32 extend to horizontal sections 34 leading out to stool supports 22, while the stools 16 closest to the center folding line include a frame with risers 33 leading to double frame members 38A and 38B.
• lateral frame members 36 provide added support to the horizontal sections 34 for the end most stools 16.
• the double frame construction provides increased strength and support for the stools 16.
• the folding mechanism 18 includes outer pivot members 26 along the folding center axis, connecting the straight edges of the two table top members 14.
• the folding mechanism 18 also includes first linkage members 42 and second linkage members 44 that attach to a pivot 46 on the frame as well as to the table top members 14 and pivot members 40 mounted to cross members 30 connecting the table risers 32 for the outermost stools.
• the lock 50 extends along the center axis of the table top members 14 and is lifted up to release complementary cam-type pivot members 26 of the folding mechanism 18.
• the lock handles 52 extend downward under the table tops 14 and near the edges for easy access with a reduced risk of pinching fingers or hands, while being hidden from view from above.
• the center portion of the lock 50 is offset from the center edges of the table tops 14 to prevent the lock from being easily grabbed there by an operator. With the center portion of the lock 50 moved to a position wherein it cannot be gripped, the chances of an operator's hands being pinched between table tops 14 are reduced. When engaged in the unfolded position, the lock 50 prevents the table from folding.
• the lock 50 also stops the folding mechanism 18 just short of fully unfolding to provide added safety for preventing the edges of the table from pinching together until the lock 50 is actuated.
• Manually holding the lock 50 open and disengaged from pivot members 26 allows the table 10 to MIy unfold.
• the folding mechanism 18 has torsion springs mounted to one or more of the cross members 30 to aid and control folding between the folded and unfolded positions. The torsion springs also assist in keeping the table 10 from folding or unfolding unexpectedly and allows for actuating the lock 50.
• the folding linkage 18 provides for folding of the table between the folded and unfolded positions in a controlled manner.
• the folding mechanism 18 also maintains the stools 16 in a substantially horizontal position in both the folded and unfolded positions. It can be appreciated that in either position, the frame 12 provides a base of support so that the table 10 cannot easily tip in either the folded or unfolded position.
• a stop 70 is utilized to aid in holding the table 10 in a wider folded travel position that provides greater stability during transport of the table 10. As the table 10 is folded, it may be easier to push in a folded position wherein the table is supported solely on the wheels 20, but is not fully folded, as shown in FIG. 8. This maintains a slightly lower center of gravity, making movement easier and safer.
• the stop 70 is pivotally mounted to the frame 12 at the underside of one of the table tops 14.
• the stop 70 includes a cross bar 72 engaging the risers 32 of the frame 12, as shown in FIG. 8.

• the stop 70 automatically drops down again when the table 10 is unfolded.
• the frame 12 provides for supporting each of the stools 16 while keeping the support members 22 attaching under the table tops out of the way of the users, even while seated.
• the frame 12 also provides easy access to the stools 16 without undue restriction.
• the horizontal portions of the frame extend inward from the stools 16 nearest the apex of the table top member 14 as well as those stools 16 along the center folding axis.
• the outer most stools 16 at each side of the table top members 14 have supports that provide an opening there between for unimpeded easy entry and exit for seating.
• the space between the stools 16 is wide enough so that there is sufficient room for passage between the stools with no obstruction from the frame members.
• the present invention provides for substantially evenly spacing the stools 16 about the periphery of the table top members 14 so that there is sufficient use of space on the table top 14 at each seated position.

• the frame 112 includes risers 132 extending out from pivots 148 underneath the semi-circular tabletop members 114.
• the tabletops 114 have arcing outer edges, shown here as a circle. It is also envisioned that other non-rectangular shapes, such as octagons or other polygons could be used, preferably a configuration with adjacent benches 116 substantially evenly spaced about the periphery of the table 110.
• the risers 132 extend to horizontal sections 134 leading out to bench supports 122, while the first ends of the benches 116 closest to the center folding line include a frame with risers 133 leading to double frame members 138A and 138B.
• the folding mechanism 118 includes outer pivot members 126 along the folding center axis, connecting the straight edges of the two tabletop members 114.

It can be appreciated that the present invention provides for fast and simple conversion between a configuration with stools 16, shown in Figure 1 and a configuration with benches 116, shown in Figure 9. Both types of seating directly mount to the frame without needing to reconfigure the frame 12 or 112 or to reconfigure the folding assembly 18 or 118.
