Foundation rebar hangers

Abstract

A series of rebar hangers for use at both a secondary primary level and a secondary level, vertically speaking for the suspension of rebar rods in footing formation. These components employ a rest head connected to a shaft, connected to a base, which base if the device is of a primary level nature has a spacer disposed on the rear side thereof. Each of the heads is conceptually interchangeable as is each of the bases interchangeable to create a fixed configuration unit for a specific mount and retention. The device's rest head is attached to or overlays a footing former, if primary; or attaches to a primary device if secondary. The base extending from the shaft is adapted to retain one or two rebar rods depending on the base's configuration.

1 . A device for the retention of rebar rods for use in the construction of footings and the like, which device comprises: 
 [a] a rest head to secure the device to a footing former;    [b] an elongated shaft, a first end of which is connected to said rest head; and    [c] a base for the retention of rebar rods in a generally horizontal position, said base being connected to the second end of said elongated shaft.    
   
   
       2 . The device of  claim 1  wherein the rest head is a nail rest head having an inverted J-shaped configuration.  
   
   
       3 . The device of  claim 1  wherein the rest head is an overlay rest head of a generally inverted U-shaped configuration.  
   
   
       4 . The device of  claim 1  wherein a spacer comprising a rearwardly disposed portion is attached to the base which spacer is adapted to rest against a surface to retain the device in a generally vertical disposition.  
   
   
       5 . The device of  claim 4  wherein the spacer is V-shaped, and is mounted at its midpoint to the base.  
   
   
       6 . The device of  claim 4  wherein the spacer is a straight spacer.  
   
   
       7 . The device of  claim 1  wherein the base is a combination base.  
   
   
       8 . The device of  claim 1  wherein the base is a hook base.  
   
   
       9 . A device for the retention of rebar rods for use in the construction of footings and the like, which device comprises: 
 [a] a rest head to secure the device to a footing former;    [b] an elongated shaft, a first end of which is connected to said rest head; and    [c] a base for the retention of rebar rods in a generally horizontal position, said base being connected to the second end of said elongated shaft wherein the rest head is a nail rest head having an inverted J-shaped configuration, and the base is a hook base and a Vee spacer is attached to the base.    
   
   
       10 . The device of  claim 9  wherein the base is a hook base having a distal leg, and a tail is extended laterally normal to the distal leg of said base.  
   
   
       11 . The device of  claim 9  wherein the hook base is replaced by a combination base of a hook and MJ configuration.  
   
   
       12 . A device for the retention of rebar rods for use in the construction of footings and the like, which device comprises: 
 [a] an overlay rest head of a generally inverted U-shape to secure the device to a footing former;    [b] an elongated shaft, a first end of which is connected to said rest head; and    [c] a base for the retention of rebar rods in a generally horizontal position, said base being connected to the second end of said elongated shaft, said base being a combination base of a hook and MJ configuration.    
   
   
       13 . The device of  claim 12 , wherein a single S-spacer is attached to and reinforces the base.  
   
   
       14 . The device of  claim 3  wherein the base is a hook base and a Vee spacer is attached at its center to the base.  
   
   
       15 . The device of  claim 1  wherein the unit is adapted to serve as a secondary retainer and wherein the head is an inverted arcuate U having its distal leg normal to the orientation of the rest of the retainer, and wherein the base is of an offset W configuration.  
   
   
       16 . The device of  claim 1  wherein the unit is formed from a single piece of drawn wire.  
   
   
       17 . The device of  claim 1  wherein the unit is formed from several pieces of wire welded together.  
   
   
       18 . The device of  claim 1  wherein the device is made of plastic.  
   
   
       19 . A combination of a primary and a secondary retainer for rebar rods, which combination comprises, a primary rebar retainer comprising a nail rest head and a combination base having a hook and MJ base, with a secondary retainer for holding rebar rods at a lower elevation than the primary rebar retainer, said secondary retainer having an inverted arcuate U-shaped rest head, and an offset W configured base.
