Structural member for enclosure

1. A structural member for an enclosure, comprising:

a first structural member section having a generally tubular cross section and at least a partially closed interior channel disposed longitudinally within said first structural member;

a pair of generally U-shaped, outwardly facing longitudinal fastener channels spaced radially apart in a substantially parallel relationship to the first structural member section, an interior wall of each U-shaped channel having a recessed ledge and an exterior wall of each U-shaped channel having a depth essentially equal to said opposed interior wall;

a second structural member section having a tubular cross-sectional area integrally disposed interiorly between the first structural member section;

said second structural member section having a pair of opposed interiorly positioned U-shaped fastener channels positioned at a bottom of said second structural member;

one or more brackets which interface with said interiorly positioned U-shaped fastener channels; and,

wherein the first and second structural member sections and one or more generally longitudinal fastener channels are contiguously formed as a unitary structural member.

2. The structural member as defined in claim 1 , wherein

the structural member is extruded.

3. The structural member as defined in claim 1 , wherein

the structural member is constructed from a metal or metal alloy.

4. The structural member as defined in claim 1 , wherein

the structural member is constructed from aluminum.

5. The structural member as defined in claim 1 , wherein

the pair of generally U-shaped, outwardly facing longitudinal fastener channels define an opening having sufficient wall thickness for receiving an associated threaded fastener.

6. The structural member as defined in claim 5 , wherein

the associated threaded fastener is infinitely positionable within the pair of generally U-shaped, outwardly facing longitudinal fastener channels.

7. The structural member as defined in claim 1 , wherein

the at least a partially closed interior channel disposed longitudinally within said first structural member has a C-shaped cross section having sufficient wall thickness for receiving a fastener axially with respect the longitudinal axis of the first generally longitudinal fastener channel, and wherein

the pair of generally U-shaped, outwardly facing longitudinal fastener channels have sufficient wall thickness for receiving a fastener radially with respect to the longitudinal axis of the pair of longitudinal fastener channels.

8. An enclosure defining a rigid enclosure shell for supporting one or more associated internal components, comprising:

at least a first structural member having a first tubular section that comprises part of the rigid enclosure shell, said first structural member having a pair of radially-spaced, exteriorly-facing U-shaped channels on opposed sides of an curvilinear exterior portion of said first structural member, an interior of said first tubular section having an at least partially closed channel disposed longitudinally within said first structural member;

said first structural member further comprising a pair of oppositely facing, interiorly positioned U-shaped channels disposed opposite said curvilinear section of said first structural member;

a means for operatively mounting the one or more associated internal components by use of one or more brackets which interface with said interiorly positioned U-shaped channels,

a means for operatively mounting said brackets with said interiorly positioned U-shaped channels, said means for operatively mounting being spaced radially apart from the first tubular section, and wherein

said means for operatively mounting is contiguously fashioned with the first tubular section; and,

one or more wall members affixed with respect to the first tubular section by fasteners which interface with said radially-spaced, exteriorly-facing U-shaped channels on opposed sides of said curvilinear exterior portion of said first structural member, and further wherein

the at least a first structural member further comprises a second tubular section disposed between the first tubular section and said pair of oppositely facing, interiorly positioned U-shaped channels disposed at a bottom of said second tubular section for interfacing with said brackets.

9. The enclosure as defined in claim 8 , wherein

the at least a first structural member is a unitary structural member.

10. The enclosure as defined in claim 8 , wherein

the at least a first structural member is extruded.

11. The enclosure as defined in claim 8 , wherein said pair of radially-spaced, exteriorly-facing U-shaped channels on opposed sides of a curvilinear exterior portion of said first structural member comprises:

a pair of channels having wall sections configured to receive a threaded fastener.

12. The enclosure as defined in claim 8 , wherein

said exteriorly-facing U-shaped channels and said interiorly-positioned U-shaped channels have respective openings that each face outward at different angles of orientation.

13. The enclosure as defined in claim 11 , further comprising:

first and second first structural members disposed at distal ends of the enclosure; and,

the one or more brackets mounted to the at least a first channel, wherein the one or more associated internal components are fastened directly to the one or more brackets.

14. The enclosure as defined in claim 13 , wherein

the one or more brackets are infinitely positionable along the length of the at least a first channel.
