Land anchor having up-slide hammer

Abstract

A land anchor device that is configured for external driving with a hammer or the like and self-contained extraction with an up-slide hammer member. Among other benefits, weight, bulk and cost-of-manufacture are reduced by a land anchor device in accordance with the present invention. The device may include a drive stake having a continuous drive member from striking surface to tip, any of and various cross-sectional configurations. The handle arrangements facilitate easy-of-use. The device includes an auger accessory. Various embodiments and fabrication materials and methods are disclosed.

1 . A land anchor device, comprising: 
 a drive stake having an exposed striking surface and an insertion tip, said drive stake including a substantially continuous member from said striking surface to said insertion tip;    a hammer member provided substantially below said striking surface, said hammer member configured for movement along said stake;    a first handle member coupled to said hammer member for manual movement of said hammer member by a user; and    an extraction anvil coupled to said stake substantially between said striking surface and said hammer member.    
   
   
       2 . The device of  claim 1 , wherein said stake has a substantially square lateral cross-sectional configuration.  
   
   
       3 . The device of  claim 1 , further comprising a second handle member, said first and second handle members being disposed on substantially opposing sides of said hammer member and configured to have a horizontal dimension that is at least two times their vertical dimension.  
   
   
       4 . The device of  claim 1 , further comprising grip material provided on said first handle member.  
   
   
       5 . The device of  claim 1 , wherein said hammer member is provided wholly below said striking surface.  
   
   
       6 . The device of  claim 1 , further comprising a hand guard member coupled to said first handle member to inhibit movement of a user's hand into a location between said hammer member and said extraction anvil.  
   
   
       7 . The device of  claim 1 , further comprising an auger member coupled to said stake.  
   
   
       8 . The device of  claim 7 , wherein said auger member is releasably coupled to said stake.  
   
   
       9 . A land anchor device, comprising: 
 a drive stake having an exposed striking surface and an insertion tip;    a hammer member configured for movement along said stake;    a first handle member coupled to said hammer member for manual movement of said hammer member by a user; and    an extraction anvil coupled to said stake substantially between said striking surface and said hammer member;    wherein said stake has a non-circular lateral cross-sectional configuration.    
   
   
       10 . The device of  claim 9 , wherein said stake has two or more longitudinally disposed sides that are substantially flat.  
   
   
       11 . The device of  claim 9 , wherein said stake has a lateral cross-sectional configuration that is rectangular, including square.  
   
   
       12 . The device of  claim 9 , wherein said stake has a lateral cross-sectional configuration that is longer than wide.  
   
   
       13 . The device of  claim 9 , wherein said hammer member is provided below said striking surface.  
   
   
       14 . The device of  claim 9 , wherein said stake includes a substantially continuous member from said striking surface to said insertion tip.  
   
   
       15 . The device of  claim 9 , further comprising a second handle member, said first and second handle members being disposed on substantially opposing sides of said hammer member and configured to have a horizontal dimension that is at least two times their vertical dimension.  
   
   
       16 . The device of  claim 9 , further comprising grip material provided on said first handle member.  
   
   
       17 . The device of  claim 1 , further comprising an auger member coupled to said stake.  
   
   
       18 . A land anchor device, comprising: 
 a drive stake having an exposed striking surface and an insertion tip, said drive stake including a substantially continuous member from said striking surface to said insertion tip;    a hammer member provided substantially below said striking surface, said hammer member configured for movement along said stake;    a first handle member coupled to said hammer member for manual movement of said hammer member by a user; and    an extraction anvil coupled to said stake substantially between said striking surface and said hammer member;    wherein said stake has a non-circular lateral cross-sectional configuration.    
   
   
       19 . The device of  claim 18 , further comprising a second handle member, said first and second handle members being disposed on substantially opposing sides of said hammer member and configured to have a horizontal dimension that is at least two times their vertical dimension.  
   
   
       20 . The device of  claim 18 , wherein said stake has a lateral cross-sectional configuration that is rectangular, including square.
