Ground anchor for use with natural ground cover

Abstract

A biodegradable ground anchor for use in conjunction with a ground cover. The anchor includes a head portion that has opposite surfaces and a peripheral surface. A pair of integral legs depend away from one of the opposite surfaces. The legs are generally parallel with respect to each other. Each of the legs includes a pair of fins. The distal end of each leg terminates in a point. The ground anchor is made from a polylactide polymer that is biodegradable.

1 . A biodegradable ground anchor for use in conjunction with a ground cover, the anchor comprising; 
 a head portion having opposite [surface] top and bottom surfaces and a peripheral surface;    a pair of integral legs depending away from one of the opposite surfaces, the legs being generally parallel with respect to each other;    each of the legs including a pair of fins;    the distal end of each leg terminating in a point intended to assist in penetrating the ground; and    the ground anchor being made From a polyactide polymer that[s] is biodegradable.    
     
     
         2 . A ground cover blanket system comprising: 
 a ground cover blanket, the blanket having cross-hatched members;    a biodegradable ground anchor for penetrating the ground, the ground anchor comprising a head portion having opposite [surface] top and bottom surfaces and a peripheral surface;    a pair of legs depending away from one of the opposite surfaces, the legs being generally parallel with respect to each other;    each of the legs including a pair of fins;    the distal leg of each leg terminating in a point; and    the ground anchor being made from a polylactide polymer that is biodegradable.    
     
     
         3 . The ground cover blanker system of  claim 2  wherein the groundcover blanket is a soil erosion control blanket.  
     
     
         4 . The ground anchor of  claim 1  wherein the head portion being generally rectangular in shape.  
     
     
         5 . The ground anchor of  claim 1  wherein the head portion being generally square in shape.  
     
     
         6 . The ground anchor of  claim 1  wherein the head portion being generally oval in shape.  
     
     
         7 . The ground anchor of  claim 1  wherein the head portion being generally circular in shape.  
     
     
         8 . The ground anchor of  claim 1  wherein the legs depend away from the bottom surface of the head portion.  
     
     
         9 . A biodegradable ground anchor for use in conjunction with a ground cover wherein the ground anchor is driven into the ground so as to retain the ground cover to the ground, the ground anchor comprising: 
 a head portion having opposite top and bottom surfaces and a peripheral surface, and the top surface of the head portion being impacted upon the ground anchor being driven into the ground;    a pair of integral legs depending away from the bottom surface of the head portion, the legs being generally parallel with respect to each other, and the legs being sufficient rigid so as to maintain their structural integrity upon being driven into the ground;    each of the legs including a pair of chevron-shaped fins;    the distal end of each leg terminating in a point that assists in the ground anchor penetrating the ground; and    the ground anchor being made from a polylactide polymer that is biodegradable so that the structural integrity of the ground anchor diminishes as the ground anchor remains in the ground.
