System, method, and apparatus for holding a track to a base

A back-to-back track assembly comprising:

• a base extrusion comprising a substantially rectangular member elongated axially on a first axis, wherein said base extrusion comprises a plurality of conduits drilled normal to said first axis at regular intervals along the length of the extrusion;
• two linear motion guide tracks, each track having a substantially rectangular end and a substantially triangular end, wherein said two linear motion guide tracks are placed on said base extrusion with said substantially triangular ends facing away form each other such that a space is formed between the two substantially rectangular ends, wherein said space is substantially the same width as the diameter of said conduit;
• a plurality of retaining washers placed on the top of said two linear motion guide tracks, said plurality of retaining washers having a washer conduit therethrough, wherein said plurality of retaining washers are placed such that each washer conduit aligns with one of said plurality of conduits;
• a plurality of nuts and bolts, wherein one of said plurality of bolts is inserted through said washer conduit, through said space, and through one of said plurality of conduits drilled in said base extrusion, wherein at least a threadable portion of the bolts extends out of said base extrusion, and wherein one of said plurality of said nuts threads onto said threadable portion, thereby forcing said retaining washer onto said two linear motion guide tracks and securing said two linear guide tracks to said base extrusion,
• a beam extrusion having at least one T-shaped beam slot having a T-shaped beam slot opening that is more narrow than the core of the T-shaped beam slot;
• and
• at least one guide wheel rotatably coupled to an axis, wherein the outermost portion of the at least one guide wheel comprises a substantially v-shaped track interface, wherein said axis is coupled with a track bar configured to be inserted into said T-shaped beam slot,
• wherein said substantially v-shaped guide wheel track interface geometrically couples with said substantially triangular end of said linear motion guide track such that the beam extrusion is linearly movable over the axial distance of said linear motion guide track.

A method of assembling a back-to-back track assembly comprising:

• providing a base extrusion comprising an elongated, substantially rectangular member, wherein said base extrusion comprises a plurality of conduits drilled at regular intervals along the length of the extrusion;
• placing two linear motion guide tracks on said base extrusion, wherein each track has a substantially rectangular end and a substantially triangular end, wherein said two linear motion guide tracks are placed on said base extrusion with said substantially triangular ends facing away form each other such that a space is formed between the two substantially rectangular ends, wherein said space is substantially the same width as the diameter of said conduit;
• placing a plurality of retaining washers on the top of said two linear motion guide tracks, wherein said plurality of retaining washers have a washer conduit therethrough, wherein said plurality of retaining washers are placed such that each washer conduit aligns with one of said plurality of conduits;
• threading a plurality of bolts through said washer conduit, through said space, and through one of said plurality of conduits drilled in said base extrusion, wherein at least a threadable portion of the bolts extends out of said base extrusion;
• threading a nut onto said threadable portion of each of said plurality of bolts, thereby forcing said retaining washer onto said two linear motion guide tracks and securing said two linear guide tracks to said base extrusion;
• providing a beam extrusion having at least one T-shaped beam slot having a T-shaped beam slot opening that is more narrow than the core of the T-shaped beam slot;
• and
• providing at least one guide wheel rotatably coupled to an axis, wherein the outermost portion of the at least one guide wheel comprises a substantially v-shaped track interface, wherein said axis is coupled with a track bar configured to be inserted into said T-shaped beam slot;
• and
• coupling the guide wheel with at least one of said two linear motion guide track, wherein said substantially v-shaped guide wheel track interface geometrically couples with said substantially triangular end of said linear motion guide track such that the beam extrusion is linearly movable over the axial distance of said linear motion guide track.
