Protective cap for reinforcing bars

Abstract

A protective cap for covering the exposed end of a concrete reinforcing bar which includes a tubular collar having an open lower end, an upper end and hollow interior, a cap perpendicularly mounted to the tubular collar and the cap having a metal plate embedded therein. A plurality of reinforcing ribs are mounted between the tubular collar and the cap providing rigidity therebetween. Protective cap includes a plurality of minor reinforcing ribs mounted between the tubular collar and the cap and interposed between the major reinforcing ribs, and finally including a plurality of fins provided within the hollow interior of the tubular collar which extends inwardly into the hollow interior adapted to grasp the exposed end of a concrete reinforcing bar.

1 . A protective cap for covering the exposed end of a concrete reinforcing bar, comprising,
 a tubular collar having an open lower end and an upper end and a hollow interior bounded by an interior wall, said tubular collar having a predetermined diametric dimension,   a cap perpendicularly mounted to said tubular collar, said cap having a metal plate embedded therein,   a plurality of major reinforcing ribs mounted between said tubular collar and said cap for providing rigidity there between,   a plurality of minor reinforcing ribs mounted between said tubular collar and said cap and interposed between said major reinforcing ribs to further enhance the rigidity therebetween,   and a plurality of fins provided within the hollow interior of said tubular collar, said fins extending inwardly into the hollow interior thereof and adapted to grasp the exposed end of a concrete reinforcing bar to accommodate the seatment of the protective cap thereon.   
     
     
         2 . A protective cap as set forth in  claim 1  above, which further includes a reinforcement ring mounted between and interconnecting said major and minor reinforcing ribs to further enhance the rigidity therebetween. 
     
     
         3 . A protective cap as set forth in  claim 1  above, which further includes a tubular insert, said insert being diametrically sized to frictionally fit within said tubular collar and said tubular collar insert provided with a plurality of fins mounted within the confines thereof and extending inwardly therefrom and adapted to grasp the exposed end of a concrete reinforcing bar to accommodate the seatment of the protective cap thereon. 
     
     
         4 . A protective cap as set forth in  claim 3  above, wherein said fins comprising plurality of major fins mounted on the interior of said tubular insert, and extending inwardly therefrom for a distance, and a plurality of minor fins mounted on the interior of said tubular insert and extending inwardly therefrom and interposed between said major fins, said major and minor fins adapted for engaging the exposed end of a bar therebetween to accommodate the mounting of said protective cap on the exposed end of a concrete reinforcing bar. 
     
     
         5 . A protective cap for covering the exposed end of a concrete reinforcing bar comprising,
 a tubular collar having an open lower end and an upper end, and a hollow interior bounded by an interior wall,   a cap perpendicularly mounted to the upper end of said collar,   said cap having a metal plate embedded therein,   said tubular collar having a plurality of major fins mounted on the interior wall and extending inwardly therefrom for a distance,   said tubular collar further including a plurality of minor fins interposed between said major fins mounted on said interior wall and extending inwardly therefrom for a distance shorter than said major fins,   said major and minor fins adapted for engaging the exposed end of a bar there between to accommodate the mounting of said protective cap on the exposed end of a concrete reinforcing bar,   and a plurality of reinforcing ribs mounted between said tubular collar and said cap to provided rigidity there between,   whereby the arrangement of the major and minor fins allows the protective cap to be mounted on the exposed end of a concrete reinforcing bar of any geometric shape.   
     
     
         6 . A protective cap as set forth in  claim 5  above, wherein said major fins are mounted on the interior wall of said tubular collar and extend inwardly for a distance, off center relative to the radius of said tubular collar. 
     
     
         7 . A protective cap as set forth in  claim 6  above, wherein said minor fins are mounted on the interior wall of said tubular collar and are interposed between said major fins, and said minor fins extending inwardly for a distance shorter than said major fins. 
     
     
         8 . A protective cap as set forth in  claim 5  above, wherein said tubular collar, cap, major fins, minor fins and reinforcing ribs are molded as a unitary structure. 
     
     
         9 . A protective cap as set forth in  claim 5  above, wherein said reinforcing ribs comprise a series of major reinforcing ribs mounted between said tubular collar and said cap, and further includes a plurality of minor reinforcing ribs mounted between said tubular collar and said cap and interposed between said major reinforcing ribs. 
     
     
         10 . A protective cap as set forth in  claim 9  above, wherein a reinforcing ring is provided, said reinforcing ring being mounted on said cap and interconnecting all of said major and minor reinforcing ribs. 
     
     
         11 . A protective cap as set forth in  claim 5  above, wherein said cap is geometrically circular in configuration and said plurality of reinforcing ribs are mounted between said tubular collar and said cap around the entire periphery of said cap. 
     
     
         12 . A protective cap as set forth in  claim 10  above, wherein said tubular collar, cap, major fins, minor fins, major reinforcing ribs, minor reinforcing ribs and reinforcing ring are molded as a unitary structure.
