Patent ID: 7063481

Claim:
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.
