Abstract

A leg for a self-supporting tower comprising a plurality of upstanding leg members having upper and lower ends. A plurality of vertically spaced-apart and horizontally disposed brace plates are secured to the leg members and extend therebetween. The brace plates have a pair of spaced-apart tie-off openings formed therein which enable a tower climber to tie-off the climber's safety harness thereto. The brace plates have an elongated wind load reducing slot formed therein between the tie-off openings. The leg is devoid of any diagonal braces extending between the leg members thereof thereby making it easier and safer for a climber to climb the tower.

Claims

exact text as granted — not AI-modified
1 . A self-supporting tower, comprising:
 a plurality of upstanding, spaced-apart tower legs having upper and lower ends;   each of said tower legs including spaced-apart first, second and third upstanding leg members having upper and lower ends;   a plurality of vertically spaced and horizontally disposed brace plates secured to and extending between said first and second leg members;   a plurality of vertically spaced and horizontally disposed brace plates secured to and extending between said second and third leg members;   a plurality of vertically spaced and horizontally disposed brace plates secured to and extending between said first and third leg members;   each of said brace plates including a generally vertically disposed plate portion having upper and lower ends and opposite ends;   at least some of said plate portions having at least one tie-off opening formed therein to enable a tower climber to selectively attach the climber's safety harness thereto.   
     
     
         2 . The self-supporting tower of  claim 1  wherein all of said plate portions have a tie-off opening formed therein. 
     
     
         3 . The self-supporting tower of  claim 1  wherein at least some of the plate portions have a pair of horizontally spaced-apart tie-off openings formed therein. 
     
     
         4 . The self-supporting tower of  claim 1  wherein all of said plate portions have a pair of horizontally spaced-apart tie-off openings formed therein. 
     
     
         5 . The self-supporting tower of  claim 1  wherein at least some of said plate portions have an elongated wind load reducing slot formed therein. 
     
     
         6 . The self-supporting tower of  claim 1  wherein all of said plate portions have an elongated wind load reducing slot formed therein. 
     
     
         7 . The self-supporting towers of  claim 3  wherein at least some of said plate portions have an elongated wind load reducing slot formed therein between said tie-off openings. 
     
     
         8 . The self-supporting towers of  claim 4  wherein at least some of said plate portions have an elongated wind load reducing slot formed therein between said tie-off openings. 
     
     
         9 . The self-supporting tower of  claim 1  wherein said brace plates have a channel-shaped cross-section. 
     
     
         10 . A tower leg for a self-supporting tower with the tower legs and towers having upper and lower ends, comprising:
 first, second and third upstanding leg members having upper and lower ends;   a plurality of vertically spaced and horizontally disposed brace plates secured to and extending between said first and second leg members;   a plurality of vertically spaced and horizontally disposed brace plates secured to and extending between said second and third leg members;   a plurality of vertically spaced and horizontally disposed brace plates secured to and extending between said first and third leg members;   each of said brace plates including a generally vertically disposed plate portion having upper and lower ends and opposite ends;   at least some of said plate portions having at least one tie-off opening formed therein to enable a tower climber to selectively attach the climber's safety harness thereto.   
     
     
         11 . The self-supporting tower of  claim 10  wherein all of said plate portions have a tie-off opening formed therein. 
     
     
         12 . The self-supporting tower of  claim 10  wherein at least some of the plate portions have a pair of horizontally spaced-apart tie-off openings formed therein. 
     
     
         13 . The self-supporting tower of  claim 10  wherein all of said plate portions have a pair of horizontally spaced-apart tie-off openings formed therein. 
     
     
         14 . The self-supporting tower of  claim 10  wherein at least some of said plate portions have an elongated wind load reducing slot formed therein. 
     
     
         15 . The self-supporting tower of  claim 10  wherein all of said plate portions have an elongated wind load reducing slot formed therein. 
     
     
         16 . The self-supporting towers of  claim 12  wherein at least some of said plate portions have an elongated wind load reducing slot formed therein between said tie-off openings. 
     
     
         17 . The self-supporting towers of  claim 13  wherein at least some of said plate portions have an elongated wind load reducing slot formed therein between said tie-off openings. 
     
     
         18 . The self-supporting tower of  claim 10  wherein said brace plates have a channel-shaped cross-section.
