A foldable support system includes a sheet metal flange depending from a table and a sheet metal leg. A pivot pin extends through a slot in the flange and an aperture in the leg so that the leg may rotate and slide relative to the flange. The flange includes a bent tab which extends toward and beyond the leg and the leg includes an arcuate cut out channel having a mouth at a side edge of the leg and a cut out receptacle at its inner end. The bent tab is received in the receptacle to lock the leg in an unfolded position when the pivot pin is at the top of the slot, while the bent tab is within the channel to permit the leg to be rotated to a folded position, when the pivot pin is at the bottom of the channel.

Having thus described the invention, there is claimed as new and desired to be secured by Letters Patent: 1. A foldable support system, the support system comprising a sheet metal flange configured to depend from a table and a sheet metal leg coupled to the flange for rotational and translational movement relative thereto, the leg and the flange being parallel to one another, a pivot pin extending through the flange and the leg, the flange including a first bent tab and the leg including a receptacle for receiving the bent tab upon translational movement of the leg and the flange relative to one another, whereby the leg may be rotated about the pivot pin from a folded position to an unfolded position, with the bent tab being thereafter seated in the receptacle to fix the leg in the unfolded position by translational movement of the leg relative to the flange. 2. A foldable support system in accordance with claim 1 wherein the receptacle comprises a cut out portion of the leg. 3. A foldable support system in accordance with claim 1 further including a slot formed in the flange, the pivot pin extending through the slot, whereby translational movement of the leg relative to the flange is guided by engagement between the pivot pin and the slot. 4. A foldable support system in accordance with claim 3 wherein the slot includes a top and a bottom and the flange includes a second bent tab, the second bent tab being registered with the longitudinal side edge of the leg adjacent to the mouth when the pivot pin is at the top of the slot and being registered with the mouth when the pivot pin is at the bottom of the slot. 5. A foldable support system in accordance with claim 3 wherein the pivot pin is positioned at a top of the slot when the leg is fixed in the unfolded position and is positioned at the bottom of the slot to commence rotation of the leg from the unfolded position to the folded position. 6. A foldable support system in accordance with claim 5 wherein the arcuate cut out channel includes a cam surface, the cam surface being engaged by the first bent tab when the leg is rotated about the pivot pin from the unfolded position toward the folded position, the engagement between the cam surface and the first bent tab causing the pivot pin to elevate from the bottom of the slot upon continued rotation. 7. A foldable support system in accordance with claim 1 further including an arcuate cut out channel formed in the leg, the receptacle being positioned at an inner end of the channel, the channel having a mouth at a longitudinal side edge of the leg. 8. A foldable support system in accordance with claim 1 further including a table, the sheet metal flange depending from the table, a second sheet metal flange depending from the table and a second leg coupled to the second flange, the legs being joined at their lower ends by a steel sheet metal stringer, whereby the table may rest on a base surface comprising a barbecue grill formed of spaced parallel rods. 9. A foldable support system for a table in accordance with claim 8 further including a further pair of sheet metal flanges depending from the table and a further pair of sheet metal legs coupled to the flanges, the further pair of legs being joined to one another at their lower ends by a second sheet metal stringer. 10. A foldable support system for a table in accordance with claim 1 wherein the sheet metal flange and the sheet metal leg comprise steel sheet metal in the order of 16 gauge. 11. A table having a foldable support system, the support system comprising a steel sheet metal flange depending from the table and a steel sheet metal leg coupled to the flange for rotational and translational movement relative thereto, the leg and the flange being parallel to one another, a pivot pin extending through the flange and the leg, a slot formed in the flange, the pivot pin extending through the slot, the flange including a first bent tab and the leg including an arcuate cut out channel extending into the leg from a mouth at a longitudinal side edge of the leg, the channel receiving the bent tab upon rotational movement of the leg relative to the flange when the pivot pin is positioned at one end of the slot, whereby the leg may be rotated about the pivot pin from a folded position to an unfolded position. 12. A table having a foldable support system for a table in accordance with claim 11 further including a cut out receptacle formed in the leg at an inner end of the channel, the first bent tab being registered with the receptacle when the leg is in the unfolded position, the first bent tab being seated in the receptacle to fix the leg in the unfolded position when the pivot pin is positioned at the other end of the slot. 13. A table having a foldable support system in accordance with claim 12 wherein the flange includes a second bent tab, the second bent tab being registered with the longitudinal side edge of the leg adjacent the mouth when the first bent tab is seated in the receptacle and being registered with the mouth when the first bent tab is not seated in the receptacle. 14. A table having a foldable support system in accordance with claim 12 wherein the slot includes a top and a bottom and the pivot pin is positioned at the top of the slot when the leg is fixed in the unfolded position and is positioned at the bottom of the slot to commence rotation of the leg from the unfolded position to the folded position. 15. A table having a foldable support system in accordance with claim 11 further including a second steel sheet metal flange depending from the table and a second steel sheet metal leg coupled to the flange, the legs being joined at their lower ends by a steel sheet metal stringer, whereby the table may rest on a base surface comprising a barbecue grill formed of spaced parallel rods. 16. A foldable support system, the support system comprising a one piece sheet metal support, the support including a pair of parallel legs, the lower ends of the legs being joined by a stringer, the support system further including a pair of steel sheet metal flanges configured to depend from a table, the legs being nested between said flanges, each leg being pivotally connected to an adjacent flange by a hinge pin for lateral stability of the table, each flange including a bent tab extending toward and beyond its pivotally connected leg, each leg including an arcuate cut out channel for accommodating the bent tab, the cut out channel extending into the leg from a mouth formed at a longitudinal edge of the leg. 17. A foldable support system for a table in accordance with claim 16, each flange further including a slot, the hinge pin extending through the slot, whereby each leg is capable of both rotational and translational movement relative to its respective flange, each leg further including a cut out receptacle formed at an interior end of the arcuate cut out channel, whereby each leg may be pivoted about its hinge pin from a folded position to an unfolded position, wherein the bent tab is registered with the receptacle and the bent tab may thereafter be seated within the receptacle to fix the leg in the unfolded position by lateral movement of the legs relative to the flange. 18. A foldable support system in accordance with claim 17 wherein each flange further includes a second bent tab, the second bent tab being registered with the mouth when the first bent tab is within the arcuate cut out channel and being registered with the longitudinal edge of the leg when the first bent tab is received in the receptacle. 19. A foldable support system for a table in accordance with claim 17 wherein the pivot pin is positioned at the top of the slot when the bent tab is seated within the receptacle. 20. A foldable support system for a table in accordance with claim 16 wherein the support comprises 16 gauge sheet metal.
