Abstract
Bolt-on clamp extrusions for fastening a track to support base extrusion for providing customers with a simple-to-assemble, customizable, reconfigurable, and user-friendly solution for reliable linear motion track assembly. A back-to-back track configuration provides a low-profile track assembly. Custom made base extrusions include deformable fingers disposed in the slot to ensure proper fit despite a variance in track size.

A system for securing a track to a support base extrusion comprising:
- a linear motion guide track comprising an axial member;
- a support base extrusion comprising at least one T-shaped slot having an opening that is more narrow than the core of the slot;
- a bolt-on clamp apparatus comprising a substantially-axial member having a substantially c-shaped cross section comprising:
- a connected end;
- and
- a pair of arms disposed in substantially parallel planes extending from the connected end, said pair of arms defining a gap therebetween, wherein each of said arms include a plurality of corresponding conduits disposed in both arms normal to said parallel planes, and spaced substantially evenly along the length of the axial member, wherein the plurality of conduits line up relative to each of said arms through the gap, and wherein the gap is configured to accept said linear motion guide track;
- a plurality of nuts inserted into the T-shaped slots of said support base extrusion, said nuts configured to resist an application of a force from the core of the slot outward toward the slot opening;
- a plurality of bolts inserted through at least some of the corresponding conduits such that each of said bolts extend through said gap and are thread into one of said plurality of nuts, wherein threading said nut results in a clamping force that is resisted by said nut, thereby causing the gap to narrow, thereby causing the bolt-on clamp apparatus to clamp onto said linear motion guide track.
A method of assembling a track system using a bolt-on clamp apparatus comprising:
- providing a support base extrusion having at least one T-shaped slot with an opening that is more narrow than the core of the slot;
- inserting a plurality of nuts into the T-shaped slots, wherein said plurality of nuts are configured to resist an application of a force from the core of the slot outward toward the slot opening;
- aligning a bolt-on clamp apparatus with said T-slot by aligning an edge of the T-slot with a raised area groove on a bottom surface of said bolt-on clamp apparatus, wherein said bolt-on clamp apparatus further comprises a substantially-axial member having a substantially c-shaped cross section comprising a connected end;
- and a pair of arms disposed in substantially parallel planes extending from the connected end, said pair of arms defining a gap therebetween, wherein each of said arms comprise a plurality of corresponding conduits disposed in both arms normal to said parallel planes and spaced substantially evenly along the length of the axial member, wherein the plurality of conduits line up on each of said arms through the gap, and wherein the gap is configured to accept said linear motion guide track;
- inserting a linear motion guide track into said gap;
- inserting a plurality of bolts through said plurality of corresponding conduits and into said plurality of nuts;
- tightening said bolts, thereby causing a clamping force that is resisted by said nuts, thereby causing said gap to close, thereby clamping said linear motion guide track in said bolt-on clamp apparatus.
A clamp apparatus for holding a linear guide track comprising:
- an axial member having a substantially c-shaped cross section consisting of:
- a connected end;
- and
- a pair of horizontally disposed arms defining a gap therebetween, wherein each of said arms comprises a conduit, and wherein the conduits line up;
- wherein the gap is configured to accept a linear guide track;
- wherein said conduits are configured to accept a bolt, such that the bolt displaces at least one of said pair of horizontally disposed arms upon the application of force by tightening a nut onto said bolt, such that the gap closes, thereby clamping onto a track inserted therein.
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;
