A polymeric connector block for interconnecting a plurality of elongate tubular members into a structure has five-sided front and back sides with an orthogonal pattern of three parallel through-apertures therethrough. A fourth through-aperture passes from the left side to the right side, intersecting two of the parallel through-apertures at 90째. A non-through aperture passes from the top side and intersects the other of the parallel through-apertures at 90째. A sixth aperture extends into the block at an intermediate angle such as 45째. There are no apertures in the bottom side. Tubular members are insertable into the apertures and lockable therein by lockscrews. Tubular members may comprise tubing, pipe, electrical conduit and the like, and may include non-tubular materials such as solid rods. A wide range of structures may be created.

What is claimed is: 1. A connector block for interconnecting a plurality of tubular members to form a structure, said connector block comprising: a generally orthogonal block comprising: a first major planar side; a second major planar side spaced from and parallel to said first major planar side;
What is claimed is: 1. A connector block for interconnecting a plurality of tubular members to form a structure, said connector block comprising: a generally orthogonal block comprising: a first major planar side; a second major planar side spaced from and parallel to said first major planar side; first, second, and third parallel through-apertures joining said first and second major planar sides and having first, second and third central axis, respectively, for receiving tubular members; a bottom side joining said first and second major planar sides; a left side joining said first and second major sides and normal to said bottom side; a right side parallel to said left side, said right side joining said first and second major sides and normal to said bottom side; an upper side parallel to said bottom side, said upper side joining said first and second major sides; a fourth through-aperture through said block for receiving a tubular member, said fourth through-aperture extending from said left side to said right side and intercepting said first and second through-apertures; a first non-through-aperture for receiving a tubular member, said first non-through aperture on said upper side and intercepting said third through-aperture; and a second non-through aperture for receiving a tubular member, said second non-through aperture entering said block at an angle intermediate 0 degrees and 90 degrees from said first non-through-aperture. 2. A connector block in accordance with claim 1, wherein said first, second and third through-apertures are substantially parallel. 3. A connector block in accordance with claim 1, wherein all said apertures have a round cross-section with like diameter. 4. A connector block in accordance with claim 3, wherein said first and second central axes are generally equidistant from said bottom side, and spaced therefrom a minimum distance P1. 5. A connector block in accordance with claim 4, wherein said minimum distance P1 is approximately 0.4 times the aperture diameter. 6. A connector block in accordance with claim 3, wherein said second and third central axes are generally equidistant from said left side, and spaced therefrom a minimum distance P2. 7. A connector block in accordance with claim 6, wherein said minimum distance P2 is approximately 0.4 times the aperture diameter. 8. A connector block in accordance with claim 1, wherein said block is formed of an organic polymer. 9. A connector block in accordance with claim 1, wherein said block is formed of one of high density polyethylene (HDPE), polycarbonate, and polypropylene. 10. A connector block in accordance with claim 9, wherein said block includes a substance for resisting absorption of ultraviolet (UV) radiation. 11. A connector block in accordance with claim 1, wherein said intermediate angle is about 20째 to about 70째. 12. A connector block in accordance with claim 1, wherein said intermediate angle is about 30째 to about 60째. 13. A connector block in accordance with claim 1, wherein said intermediate angle is about 45째. 14. A connector block in accordance with claim 1, further comprising lockscrew pilot holes in said block to intersect with said apertures, whereby screws driven thereinto contact and/or pass into said tubular members inserted into said apertures. 15. A connector block in accordance with claim 13, wherein said lockscrew pilot holes comprise: first and second lockscrew pilot holes entering said bottom side and directed to the intersection of said fourth through-aperture with said first through-aperture and the intersection of said fourth through-aperture with said second through-aperture, respectively; third lockscrew pilot hole entering one of said major sides and directed to the intersection of said third through-aperture and said first non-through-aperture; and fourth lockscrew pilot hole entering one of said major sides and directed to said sixth aperture. 16. A connector block in accordance with claim 1, further comprising an angular side formed by truncating the comer between said upper side and said right side at an angle normal to the central axis of said second non-through-aperture. 17. A connector block in accordance with claim 1, wherein said tubular material comprises one of rigid pipe, rigid tubing, and rigid electrical conduit and is formed from one of metal, plastic, glass, ceramics, and combinations thereof. 18. A lightweight easily assembled/disassembled articulate structure formed of a plurality of sections of tubular material rigidly conjoined by connector blocks in accordance with claim 1. 19. A structure in accordance with claim 18, further comprising a plurality of semirigid panels attached to and covering a portion of said structure. 20. A connector block in accordance with claim 1, wherein said connector block is formed of a high density polyethylene prepared from recycled polyethylene containers.
