Claims7
A universal connector, comprising:
- a) a plurality of connector brackets, wherein each connector bracket comprises:
- i) a first side;
- ii) a second side orthogonal to the first side;
- iii) a third side orthogonal to both the first side and the second side;
- iv) a first curved channel aligned along a first axis where the first side and the second side meet;
- v) a second curved channel aligned along a second axis where the first side and the third side meet;
- and
- vi) a third curved channel aligned along a third axis where the second side and the third side meet;
- wherein the plurality of connector brackets attach together to form a structure having at least one opening formed by the channels into which a plurality of tubes or rods can be placed;
- and
- b) at least one diagonal member having an opening into which a tube or rod can be placed, wherein the at least one diagonal member is variably attached to the structure such that the diagonal member can be aligned at an angle between 0 and 90 degrees in relation to at least one of the openings in the structure.
