ABSTRACT:
This invention provides a double-bar connecting device which in one embodiment includes a cubic connector housing having three pairs of mutually orthogonal opposing surfaces. Each surface has two holes passing through to allow elongated bars having the same cross-section as the holes to snugly and tightly extend through the connector housing. Bolts may be provided to further secure the elongated bars to the connector housing. By positioning a number of such connector devices together with the elongated bars extending between connector housings, a three-dimensional frame structure is provided.
