Abstract
Abstract A ground anchor apparatus drivable into the earth by first and second hollow driving rods, the anchor apparatus having a pile member with an elongated generally flat primary blade and a secondary blade fixed to the primary blade with sections extending outwardly from each of the flat sides of the primary blade at right angles thereto. One end of the primary blade is pointed to form an earth piercing end, and the opposite end is provided with a pair of slots thereon spaced equally from the plane of the secondary blade. An annular collar is seated in the slots and fixed to the primary blade, its central opening straddling the slotted end of the primary blade and arranged to receive an end of the first hollow driving rod therein, permitting the pile member to be driven into the earth by force applied to the first driving rod. A U-shaped, deformable wedge has a connector member extending from its apex in a direction away from the legs of the wedge. The free end of the connector member extends toward an object on the surface of the ground and is there eventually coupled to tie down means in order to confine the object and attach it to the embedded anchor apparatus. The legs of the wedge pass through the opening in the collar, one leg positioned on each side of the primary blade and each leg being confronted by a wedge guiding edge on the extending sections of the secondary blade. The guiding edges are constructed and arranged to contact the adjacent leg of the wedge when the wedge is driven downward through the annular collar and against the guiding edges by the second hollow driving rod which is inserted over the connector member to contact the apex of the wedge. Downward force applied to the second driving rod forces the legs of the wedge through the collar and against the guiding edges, the annular collar and the guiding edges cooperating to deform the legs of the wedge outwardly from the pile member along a curve so as to assume a splayed position resistant to extraction of the pile member from the earth. The first and second driving rods are removed from the anchor apparatus after driving it into the earth and the tie down means then coupled to the connector member.

Claim 1
Independent Claim
318 words
A ground anchor apparatus to be driven into the earth by first and second hollow driving rods comprising: a pile member including an elongated generally flat primary blade with an earth piercing end and a driving end and further including a secondary blade fixed to said primary blade with sections extending outwardly from each of the flat sides of said primary blade, said primary and secondary blades cooperating to resist rotation of the pile member when embedded in the earth; said pile member further including a collar fixed to the driving end of said primary blade with the opening in said collar straddling the driving end, the opening in said collar being arranged to removably receive an end of the first hollow driving rod therein permitting the pile member to be driven into the earth a predetermined distance by force applied to the first driving rod; a U-shaped deformable wedge having a connector member extending from the apex of said wedge in a direction away from the legs of said wedge, the connector member adapted to removably slide within the hollow interior of the first and second driving rods, the legs of said wedge passing through the opening of said collar with one leg positioned on each side of said primary blade; and each of said sections of said secondary blade having a wedge guiding edge constructed and arranged to contact and guide a leg of said wedge when the wedge is driven through the collar and against the guiding edge, and to cause the leg to be deformed outwardly from the pile member so as to resist extraction of the already driven pile member from the earth, the collar and guiding edges cooperating to deform the legs of said wedge when the second driving rod is removably received about said connector member and driven downwardly against the apex of said wedge, urging the wedge through said collar.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
54 words
The combination according to claim 2 wherein said collar has an inner annular flange contacting the base of said slots, the flange bearing against said legs of said wedge to increase the rate of bending of said legs as they are forced through said collar and against said guiding edges of said secondary blade.
