Abstract
A support stand is formed from three orthogonally oriented intersecting slat pairs, with the joints at this intersection and also spaced along the support stand being of a special interlocking construction which creates a quite rigid joint in all dimensions of possible movement without the use of any fasteners or adhesive. Although the possible manifestations of products using the basic stand construction are quite varied, the illustrated embodiments include a support rack or "tree", a table, and a lamp.
Claims13
A support stand comprising:
- (a) A three-dimensional joint defining orthogonal X, Y, and Z directions comprising:
- (i) a plurality of elongated structural member pairs formed into an X-directional parallel contiguous pair, a Y-directional parallel contiguous pair, and a Z-directional parallel contiguous pair;
- (ii) said parallel contiguous pairs intersecting one another to define said joint between six elongated structural members such that said joint has:
- (1) three elongated structural members that are only fully notched, said full notch being of length substantially equal to twice the thickness of said structural members and of depth substantially equal to half the thickness of said structural members such that when paired with an oppositely-directed full notch defines a paired pass-through opening for a pair of members which pair will snugly fit into the paired pass-through opening when inserted orthogonally therethrough;
- (2) two of said members having similar full notches and also having an additional half notch, said half notch being formed at 90 degrees to the full notch and substantially at mid-span of the full notch;
- and,
- (3) the sixth elongated structural member having no notches at said joint and being the key post that holds the remaining five members together as a joint;
- (iii) said joint comprising an interlocking joint held together by the interlocking configurations of the elongated structural members themselves such that said lattice is rigid and completely integral without the use of blocks or sockets at the joints;
- and,
- (b) two of said parallel contiguous pairs each extending mutually orthogonally outward horizontally beyond said joint to define a cross support base having four extended legs;
- and,
- (c) the third of said contiguous pairs extending upright from said support base well beyond said joint to define a vertical support post.
