Anchor for embedment in concrete members

Abstract

The present invention is directed towards a lifting anchor for embedment in a concrete member. The anchor comprises a flat bar having a top and bottom; an upper and lower end; and a front and back face. The bar has an aperture near the upper end of the bar for insertion of a locking device that can be attached to a shackle for lifting the concrete wall or element containing the anchor. The bar may have additional apertures for insertion of reinforcing bars. The bar may contain side concave sections. The concave shaped sections allow for reinforcement bars to be positioned within the sections. The bar also contains crescent shaped protrusions. The protrusions extend outwardly from the bar from the front and rear faces of the bar.

1 . A concrete anchor comprising: 
 a bar having a top, a bottom, an upper end, a lower end, a first side, a second side, a front face, a back face, a first aperture, a first concave section positioned on the first side of the bar, a second concave section positioned on the second side of the bar, and crescent shaped protrusions which extend outwardly from the front and back faces of the bar.    
     
     
         2 . The concrete anchor of  claim 1  wherein the bar has a second aperture.  
     
     
         3 . The concrete anchor of  claim 1  wherein the top of the bar further comprises a first apex section, a first upwardly projecting face, a top platform section, a second upwardly projecting face, and a second apex section.  
     
     
         4 . The concrete anchor of  claim 1  wherein the top of the bar further comprises a first rectangular section, a first upwardly projecting face, a top platform section, a second upwardly projecting face, and a second rectangular section.  
     
     
         5 . The concrete anchor of  claim 1  wherein the bottom of the bar further comprises a first protrusion, a first upwardly projecting face, a bottom platform section, a second upwardly projecting face, and a second protrusion.  
     
     
         6 . The concrete anchor of  claim 1  wherein the bottom of the bar further comprises a foot section which comprises a first upwardly projecting face, a foot platform section, a second upwardly projecting face, and a second protrusion.  
     
     
         7 . The concrete anchor of  claim 1  wherein the first and second concave sections are positioned on the lower end of the bar.  
     
     
         8 . The concrete anchor of  claim 1  wherein the bar further comprises a third concave section positioned on the first side of the upper end of the bar, and a fourth concave section positioned on the second side of the upper end of the bar.  
     
     
         9 . A concrete anchor comprising: 
 a bar having a top, a bottom, an upper end, a lower end, a first side, a second side, a front face, a back face, a first aperture, a first concave section positioned on the first of the bar, a second concave section positioned on the second side of the bar, and crescent shaped protrusions which extend outwardly from the front and back faces of the bar;    wherein the top of the bar further comprises a first rectangular section, a first upwardly projecting face, a top platform section, a second upwardly projecting face, and a second rectangular section; and    wherein the bottom of the bar further comprises a foot section which comprises a first upwardly projecting face, a foot platform section, a second upwardly projecting face, and a second protrusion.    
     
     
         10 . The concrete anchor of  claim 9  wherein the first and second concave sections are positioned on the lower end of the bar.  
     
     
         11 . The concrete anchor of  claim 9  wherein the bar further comprises a third concave section positioned on the first side of the upper end of the bar, and a fourth concave section positioned on the second side of the upper end of the bar.  
     
     
         12 . A concrete anchor comprising: 
 a bar having a top, a bottom, an upper end, a lower end, a first side, a second side, a front face, a back face, a first aperture, a first concave section positioned on the first of the bar, a second concave section positioned on the second side of the bar, and crescent shaped protrusions which extend outwardly from the front and back faces of the bar;    wherein the top of the bar further comprises a first apex section, a first upwardly projecting face, a top platform section, a second upwardly projecting face, and a second apex section; and    wherein the bottom of the bar further comprises a first protrusion, a first upwardly projecting face, a bottom platform section, a second upwardly projecting face, and a second protrusion.    
     
     
         13 . The concrete anchor of  claim 12  wherein the first and second concave sections are positioned on the lower end of the bar.  
     
     
         14 . The concrete anchor of  claim 12  wherein the bar further comprises a third concave section positioned on the first side of the upper end of the bar, and a fourth concave section positioned on the second side of the upper end of the bar.
