Hole digger

Abstract

The present invention relates to post hole diggers. In particular, the present invention describes a post hole digger that constructs uniform diameter holes. The post hole digger of the present invention is comprised of a pair of handles, digging scoops and a hinge bracket. The hinge bracket translates the movement of the handles into movement of the scoops. The hinge bracket restricts the movement of the handles as digging occurs, allowing for the construction of a relatively straight-sided posthole, essentially removes the tapering of a hole as the hole becomes deeper.

         8 . A hole digger for making uniform diameter holes, comprising: 
 two elongated handles each with a first end and a second end,    a digging scoop fixedly attached to the first end of each handle, and    a hinge bracket securely attached on and between each of said handles,    wherein said digging scoops are movably joined to each other.    
     
     
         9 . A hole digger according to  claim 8  wherein said elongated handles are made of wood and are approximately 4 to 6 feet long.  
     
     
         10 . A hole digger according to  claim 8  wherein said hinge bracket is located at a midpoint between the said second ends of each of said elongated handles and the top of said scoop.  
     
     
         11 . A hole digger according to  claim 8  wherein the said hinge bracket is located between the top of said scoops and the midpoint of said elongated handles.  
     
     
         12 . A hole digger according to  claim 8  wherein said digging scoops are made of hardened steel.  
     
     
         13 . A hole digger according to  claim 8  wherein said hinge bracket is removably secured to each of said two handles by a screw.  
     
     
         14 . A hole digger according to  claim 8  wherein said hinge bracket is made of hardened steel.  
     
     
         15 . A hole digger according to  claim 8  wherein said scoops are securely joined by a bolt.  
     
     
         16 . A hole digger according to  claim 8  wherein said scoops are made of fiberglass.  
     
     
         17 . A hole digger according to  claim 8  wherein the upper portion of each of said digging scoops has a first side which defines a slot and a second side which defines a hole for a protrusion  
     
     
         18 . A hole digger of  claim 17  wherein said protrusion is a bolt.  
     
     
         19 . A hole digger according to  claim 18  wherein the said bolt has a head wider that the said slot of the said second scoop.  
     
     
         20 . A hole digger according to  claim 8  wherein 
 one of said digging scoops has at least one protrusion on the upper portion of said scoop,  
 a second digging scoop has at least one slot defined by the upper portion of said second scoop wherein said at least one protrusion passes through and slides along said at least one slot allowing for sliding movement of the said second scoop.  
 
     
     
         21 . A hole digger of  claim 20  wherein said protrusion is a bolt.  
     
     
         22 . A hole digger according to  claim 21  wherein the said bolt has a head wider than said slot of the said second scoop.  
     
     
         23 . A hole digger for making uniform diameter holes comprising: 
 two elongated unitary parts each with two ends wherein one end is formed into a digging scoop and the remaining portion is formed into an elongated handle; and    a hinge bracket securely attached on and between each of said handles.    
     
     
         24 . The hole digger of  claim 23  wherein said hinge bracket is located at a midpoint between the end of each of said elongated handles and the top of said scoops.  
     
     
         25 . The hole digger of  claim 23  wherein said hinge bracket is located between the said end where the said scoops are formed and the midpoint of said elongated handles.
