Adjustable shoring post

Abstract

A shoring post comprising: an outer tube; an inner tube slidably received within the outer tube, at least one of the inner tube and the outer tube being rotatable relative to the other; coarse adjustment means for limiting travel of the inner tube into the outer tube, the coarse adjustment means having: a rotatable collar located at one end of the outer tube; and an affixing means for affixing the collar to the inner tube; and fine adjustment means at one end of the post, comprising a threaded cylinder and a threaded receiver, wherein a selected one of the threaded cylinder and threaded receiver is integral with a selected one of the outer or inner tubes, whereby rotation of the selected one of the outer or inner tubes effects the fine adjustment.

1 . A shoring post comprising: 
 i) an outer tube;    ii) an inner tube slidably received within said outer tube, at least one of said inner tube and said outer tube being rotatable relative to the other;    iii) coarse adjustment means for limiting travel of said inner tube into said outer tube, said coarse adjustment means having: 
 a rotatable collar located at one end of said outer tube; and  
 an affixing means for affixing said collar to said inner tube; and  
   iv) fine adjustment means at one end of said post, comprising a threaded cylinder and a threaded receiver,    wherein a selected one of said threaded cylinder and threaded receiver is integral with a selected one of said outer or inner tubes, whereby rotation of said selected one of said outer or inner tubes effects said fine adjustment.    
   
   
       2 . The shoring post of  claim 1  wherein said fine adjustment means is located coaxially with the vertical axis of said inner and outer tubes.  
   
   
       3 . The shoring post of claims  1  wherein said fine adjustment means is located at the bottom of said shoring post.  
   
   
       4 . The shoring post of  claim 6  further comprising a base plate integral to said fine adjustment means.  
   
   
       5 . The shoring post of  claim 1  further comprising an extension attachable to said outer tube or said inner tube.  
   
   
       6 . The shoring post of  claim 8  further comprising a drop head attachable to said extension.  
   
   
       7 . The shoring post of  claim 1  further comprising a drop head attachable to said outer tube or said inner tube.  
   
   
       8 . The shoring post of  claim 1  wherein said threaded cylinder is integral to said inner tube.  
   
   
       9 . The shoring post of  claim 1  wherein said threaded receiver is integral to said inner tube.  
   
   
       10 . The shoring post of  claim 8  wherein rotation of said inner tube effects said fine adjustment.  
   
   
       11 . The shoring post of  claim 9  wherein rotation of said inner tube effects said fine adjustment.  
   
   
       12 . The shoring post of  claim 1  wherein said threaded receiver is integral to said outer tube.  
   
   
       13 . The shoring post of  claim 1  wherein said threaded cylinder is integral to said outer tube.  
   
   
       14 . The shoring post of  claim 12  wherein rotation of said outer tube effects said fine adjustment.  
   
   
       15 . The shoring post of  claim 13  wherein rotation of said outer tube effects said fine adjustment.  
   
   
       16 . The shoring post of  claim 1  wherein said collar includes a handle.  
   
   
       17 . The shoring post of  claim 16  wherein said handle includes a hole for receiving a striping bar.
