Tie down stake

Abstract

A tie down stake for anchoring small aircraft or other objects to the ground in any soil conditions and which consists of a central hub with an eyelet and arms which extend away from the hub. At the opposite end of each arm consist of holes that serve as stake guides for directing a plurality of anchoring rods at a fixed angle downward and inward into the ground. Thus joined by the arms and hub, the anchoring rods cooperate together to form a secure earth anchor. Also disclosed is a rod extraction tool.

I claim:  
     
         1 . A tie down stake comprising: 
 a plurality of elongate anchoring rods, each of said rods having a first end and a second end, said first end being sharpened to penetrate the ground and said second end being blunt to receive the blows of a hammer, said second end having a head means by which to grip said rods such as a bolt head,    and a central hub, said hub having an upper surface and a ground-contacting lower surface, said hub having an eyelet attached thereto and said hub having a plurality of extensions, said extensions connecting said arms, each of said arms having a first end and a second end, said first end being attached to the hub, said second end having holes being formed at an angle such that when said ground-contacting lower surface of said hub and arms placed on the ground and said rods are inserted through said arm holes, said holes being slightly larger in diameter than said rods, said rods are directed downward and inward into the ground thereby cooperating to form a secure, temporary earth anchor.    
     
     
         2 . A tie down stake as in  claim 1  wherein said solid central hub is made of a polymer, metal, or other appropriate material.  
     
     
         3 . A tie down stake as in  claim 1  wherein said solid central hub connecting the three arms contains three of said holes at the end of each arm, and wherein there are three of said anchoring rods.  
     
     
         4 . A tie down stake as in  claim 1  wherein said head means of said elongate anchoring rods comprised of a blunt end of said rods in order to receive the blows of a hammer.  
     
     
         5 . A tie down stake as in  claim 1  wherein said rods are made of a material selected from the group consisting of metal such as titanium, steel, and/or stainless steel alloy.  
     
     
         6 . A tie down stake as in  claim 1  further comprising a rod extraction tool, said rod extraction tool having a handle and a gripping means for gripping said head means of said rods and applying torsion and tensile force to said rods to aid in extracting said rods from the ground.  
     
     
         7 . A tie down stake comprising: 
 three elongate metal anchoring rods, each of said rods having a first end and a second end, said first end being sharpened to penetrate the ground and said second end being blunt to receive the blows of a hammer, said second end having a hexagonal shaped head by which to grip said rods, and a solid central hub made of a polymer, aluminum or steel, said hub having an upper surface and a ground-contacting lower surface, said hub having an eyelet attached thereto and having three small extensions with which to attach said arms extending away from hub, said holes on opposite ends of arms being slightly larger in diameter than said rods, and said holes being formed at an angle such that when said ground-contacting lower surface of said hub and arms are placed on the ground and said rods are inserted through said holes, said rods are directed downward and inward into the ground thereby cooperating to from a secure, temporary earth anchor.    
     
     
         8 . The tie down stake of  claim 7 , wherein said solid central hub is of sufficient rigidity that when said lower surface of said hub is placed on the ground and said arms and rods are inserted through said holes, said hub, said arms, and said rods cooperate as an essentially rigid unit to resist dislodgement of the tie down stake from the ground when a force is exerted on said eyelet.  
     
     
         9 . A earth ground anchor, comprising: 
 a plurality of elongate anchoring rods, each of said rods having a insertion end and a contact end, said insertion end configured to penetrate earth ground and said contact end configured to receive external force thereon, and a central hub having a plurality of extensions, said extensions connecting a plurality of arms, each of said arms having a first end and a second end, said first end being attached to said hub, said second end extending horizontally from said hub, said second end having holes therein, said holes are positioned at an angle such that when said earth ground anchor is placed in a earth ground attachment position, said insertion end of said rods are positioned for angular penetration into said earth ground, wherein when said rods are inserted into said earth ground, said rods and hub cooperatively form an anchor that resists extraction therefrom.    
     
     
         10 . The anchor of  claim 9 , wherein said second end comprises a head means by which to grip said rods.  
     
     
         11 . The anchor of  claim 9 , wherein said hub comprises an upper surface and a ground-contacting lower surface.  
     
     
         12 . The anchor of  claim 9 , wherein said holes comprises a diameter adapted to allow insertion of said rods therethrough.  
     
     
         13 . The anchor of  claim 9 , wherein said hub comprises an attachment means for attaching a cord thereto.  
     
     
         14 . The anchor of  claim 13 , wherein said attachment means is an eyelet.  
     
     
         15 . A rod extraction tool, comprising a T handle as a means for operator to grip connecting extraction tool, a socket and a perpendicular slide bar with which to grip rod head. Slide bar is either in the open or closed position. The open position allowing the release of rod head from said socket, and closed position to prevent rod head from being released from said socket:
