Rebar Support Chair

Abstract

A chair for supporting and spacing concrete reinforcement members having an integrally formed body including an upper receiving area and a lower base, where the receiving area includes a vertical fin defining an open notch for receiving a concrete reinforcement member. The receiving area may further include a gusset projecting from the vertical fin and extending upward to define a medial, lowest portion of the associated open notch. The vertical fin and gusset are adaptable such that chairs having different heights can be manufactured using a single molding apparatus.

1 . A chair for supporting and spacing concrete reinforcement members, comprising: 
 an integrally formed body including an upper receiving area and a lower base,    the receiving area including a vertical fin defining an open notch for receiving a concrete reinforcement member, and    the base adapted to rest on a planar support surface.    
     
     
         2 . The chair of  claim 1 , wherein the receiving area further includes a gusset projecting from said vertical fin.  
     
     
         3 . The chair of  claim 2 , wherein the gusset extends upward to further define a medial, lowest portion of an associated open notch.  
     
     
         4 . The chair of  claim 2 , wherein the receiving area includes a pair of opposing gussets projecting perpendicularly from the vertical fin.  
     
     
         5 . The chair of  claim 4 , wherein the base includes four supporting legs, with two of the legs being projections extending from the vertical fin.  
     
     
         6 . The chair of  claim 4 , wherein the base includes four supporting legs, with two of the legs being projections extending from the opposing gussets.  
     
     
         7 . The chair of  claim 1 , wherein the receiving area includes four vertical fins defining two pairs of diametrically opposed open notches, the medial, lowest portions of the first pair of opposed open notches being located at a different height above the support surface than the medial, lowest portions of the second pair of opposed open notches.  
     
     
         8 . The chair of  claim 7 , wherein the receiving area further includes a gusset projecting inwardly from each vertical fin.  
     
     
         9 . The chair of  claim 8 , wherein each gusset extends upward to further define a medial, lowest portion of an associated open notch.
