A foldable support structure serving as a work surface having apertures that may differ diametrically for support of containerized articles, such as beverages. The foldable support structure has three hinged planar sections with the center section having the aforementioned apertures and the left and right sections incorporating means for fixedly engaging each other. Mating straps extend substantially from a hinged joint and from a section base whereby said foldable support can be suspended from a structure, such as a motor vehicle seat. Tongue and slots positioned on opposing section ends provide means for selectively varying the pitch of the work surface. The device can be used as a free standing table for bed or beach having selectively engageable locking mechanisms positioned on the four corners of the center section and normally in a disengaged position so that the left and right sections are free to move to a user selective engagement between tab and slot.

The invention claimed is: 1. A foldable support structure apparatus comprising: a) a substantially planar central plate having a front end and a rear end and a plurality of apertures disposed therein; b) a substantially planar rear plate extending from said rear end of said central plate; c) a substantially planar front plate extending from said front end of said central plate; d) a hinge element transitionally connecting said central plate with said front plate and said second plate; e) means for securing said support structure to a seat in a motor vehicle; f) means for enabling a user to selectively adjust the pitch of said central plate when secured to said vehicle seat; and g) wherein said pitch adjustment means comprises elongated tongue members, one extending from the distal end of each of said front plate and said rear plate, and a plurality of mating slots disposed proximal of each of said distal ends thereof. 2. A foldable support structure apparatus as recited in claim 1, wherein said hinge element is a living hinge. 3. A foldable support structure apparatus as recited in claim 2, wherein said hinge element further includes a sliding lock mechanism to secure said first plate and said second plate at right angles with reference to said central plate. 4. A foldable support structure apparatus as recited in claim 3, wherein said front plate and said rear plate are positioned at right angles in reference to said central plate and locked into position with said sliding locks for use as a freestanding table or stand. 5. A foldable support structure apparatus as recited in claim 1, wherein said pitch adjustment means further includes nubs disposed on the sides of said tongues with mating nub socket located within said slots. 6. A foldable support structure apparatus as recited in claim 1, wherein said seat securing means includes a pair of straps extending from the proximal end of said rear plate and another pair of straps extending from the distal end. 7. A foldable support structure apparatus as recited in claim 6, wherein said straps are elastomeric. 8. A foldable support structure apparatus as recited in claim 7, wherein said straps extending from said proximal end of said rear plate serve to suspend said support structure from the headrest of the seat with the distal ends of said straps connecting to one another by means of a clip buckle. 9. A foldable support structure apparatus as recited in claim 8, wherein said straps extending from said distal end of said rear plate wrap around the seat and the distal ends thereof are secured to one another by means of a hook and eye fastener.
