Multifunctional pole

Abstract

A multifunctional pole to which equipment can be attached includes a plurality of pillars. The plurality of pillars forms facing surfaces that face each other. At least a facing surface of a first pillar of the plurality of pillars includes a groove part extending in a longitudinal direction of the first pillar.

What is claimed is: 
     
         1 . A multifunctional pole to which equipment can be attached, comprising:
 a plurality of pillars, wherein   the plurality of pillars forms facing surfaces that face each other, and   at least a facing surface of a first pillar of the plurality of pillars includes a groove part extending in a longitudinal direction of the first pillar.   
     
     
         2 . The multifunctional pole according to  claim 1 , wherein
 a facing surface of each of the plurality of pillars includes a groove part extending in a longitudinal direction of the each pillar.   
     
     
         3 . The multifunctional pole according to  claim 1 , wherein
 the first pillar includes a through hole extending in the longitudinal direction of the first pillar.   
     
     
         4 . The multifunctional pole according to  claim 3 , further comprising a node member that connects the plurality of pillars to each other. 
     
     
         5 . The multifunctional pole according to  claim 4 , wherein
 the node member includes an outer shell part, a nodal cavity part surrounded by the outer shell part, and an outer shell hole provided on the outer shell part, and   a junction hole that spatially connects the nodal cavity part and the through hole of the first pillar is provided on the node member and the first pillar.   
     
     
         6 . The multifunctional pole according to  claim 1 , wherein
 the groove part of the first pillar includes:
 a narrow part arranged at a surface side of the first pillar; and 
 a wide part wider than the narrow part and arranged at an inner side of the first pillar than the narrow part is. 
   
     
     
         7 . The multifunctional pole according to  claim 6 , wherein
 the groove part of the first pillar locally includes an opening part where the narrow part does not exist.   
     
     
         8 . The multifunctional pole according to  claim 6 , further comprising a fixing member to fix the equipment to the first pillar, wherein
 the fixing member includes:
 a first part narrower than the narrow part; and 
 a second part wider than the narrow part and narrower than the wide part.
