Arm connection for a structural member

Abstract

A structural member with an improved arm connection is provided with a first thru-vang that has a plurality of apertures disposed therein that is secured to the structural member. A second thru-vang is disposed adjacent the first thru-vang and has a plurality of apertures also. The second thru-vang is also secured to the structural member. In addition, a plurality of pins are received through the plurality of apertures in the first thru-vang and the plurality of apertures in the second thru-vang, which are axially aligned. An arm bracket is coupled to the first thru-vang and the second thru-vang by the plurality of pins such that each of the plurality of pins extends between the first thru-vang and the second thru-vang. Last, an arm secured to the arm bracket for support electrical conductors.

       5 . The structural member of  claim 1  wherein the arm bracket is U-shaped. 
   
   
       6 . The structural member of  claim 1  wherein the plurality of pins are cotter pins. 
   
   
       7 . The structural member of  claim 1  wherein the plurality of pins are hitch pins. 
   
   
       8 . The structural member of  claim 1  wherein the plurality of pins are rods that are at least partially threaded. 
   
   
       9 . The structural member of  claim 1  wherein the plurality of pins have threaded bolts disposed transversely on each end. 
   
   
       10 . A structural member including an arm connection comprising:
 a first thru-vang extending laterally through the structural member and having a plurality of apertures disposed therein, the first thru-vang welded to the structural member;   a second thru-vang adjacent the first thru-vang and having a plurality of apertures therein, the second thru-vang extending laterally through the structural member and welded thereto;   a plurality of pins being received through the plurality of apertures in the first thru-vang and the plurality of apertures in the second thru-vang which are axially aligned;   an arm bracket coupled to the first thru-vang and the second thru-vang by the plurality of pins such that each of the plurality of pins extends between the first thru-yang and the second thru-vang; and   an arm secured to the arm bracket.   
   
   
       11 . The structural member of  claim 10  further comprising at least one cross brace joined between the first thru-vang and the second thru-vang for structural support. 
   
   
       12 . The structural member of  claim 10  further comprising a plurality of conduits joined between each of the plurality of apertures of the first thru-vang and the second thru-vang for structural support and to aid in insertion of the plurality of pins. 
   
   
       13 . The structural member of  claim 10  wherein the arm bracket is U-shaped. 
   
   
       14 . The structural member of  claim 10  wherein the plurality of pins are cotter pins. 
   
   
       15 . The structural member of  claim 10  wherein the plurality of pins are hitch pins. 
   
   
       16 . The structural member of  claim 10  wherein the plurality of pins are rods that are at least partially threaded.
