Claims
- 1. An anchoring system including an anchor member comprising a solid wedge-shaped head having top and bottom sides bounded by a rear edge and two side edges, said side edges tapering to a front point, a centrally positioned channel extending from the front point to said rear edge, said head being provided with two holes therethrough, the holes being substantially equally spaced from the centroid of said head and from said channel, a rod-like neck secured to one side of said head within said channel, so that a portion of said neck protrudes beyond said rear edge, wherein at least part of the rear portion of said head is bent so as to form at least one wing along at least a portion of said rear edge, said wing being positioned on each side of said channel, a self-tightening clamp comprised of an essentially J-shaped clamp member provided with a plurality of apertures extending therethrough and at least one elongated opening extending therethrough, a strap securing shaft provided with a plurality of apertures, and at least one elongated opening therein, bolt means for securing said shaft within said clamp member, a cable attached to and extending between said anchor member and said clamp, and drive pole means for engaging the portion of said neck extending beyond said rear edge and for embedding said anchor member.
- 2. An improved anchor head comprising a thin, wedge-shaped head having top and bottom sides, bounded by two side edges and a rear edge, said side edges tapering to a front point, means for securing an anchor line to said head so that tension forces exerted along the anchor line are distributed substantially uniformly across said head, means for embedding said head, said embedding means being secured to one of the sides of said head, wherein at least a portion of the rear of said head is bent angularly in the direction of said bottom side so as to form at least one wing along at least a portion of said rear edge.
- 3. An improved anchor head as claimed in claim 2 wherein the rear portion of said head is bent downwardly from the plane formed by the top side of said head at an angle of from about 10.degree. to about 40.degree..
- 4. An improved anchor head as claimed in claim 3 wherein said angle is 25.degree..
- 5. A self-tightening clamp for use with securing straps comprising: an essentially J-shaped clamp member having a short side and a long side each with an interior and exterior surface; means defining a slot located along the bent portion of said J-shaped clamp member joining said long and short sides for receiving the securing strap; securing means for securing said J-shaped clamp member to an anchoring cable, a strap securing shaft on which the strap can be wound, said shaft being rotatably mounted interiorly within said J-shaped clamp member parallel to the slot; means to engage at least a portion of the interior surfaces of said short and long sides with the securing strap wound on said shaft so that as tension is applied on the securing strap in a direction opposite to the direction in which the securing strap is wound on said shaft, said short side is moved into tighter engagement with the securing strap.
- 6. A clamp as claimed in claim 5 wherein certain ones of said plurality of apertures in said shaft are offset circumferentially from the other ones of said plurality of apertures.
- 7. A method of forming an anchor head comprising the steps of:
- forming a flat wedge-shaped head having two side edges tapering together so as to form a front driving point and a rear edge;
- deforming said head so as to form a rib on one side of said head and a channel on the other side of said head, said rib and said channel extending between said front point and said rear edge;
- securing at least a portion of a rod within said channel so that a remaining portion of said rod extends beyond the rear edge of said head;
- bending the rear portion of said head so as to form wings on each side of said rod; and
- forming two apertures equally spaced from the centroid of said head and from said rod.
BACKGROUND OF THE INVENTION
The present application concerns an improved anchoring system and anchor head device and is a continuation-in-part application from a copending application U.S. patent application Ser. No. 532,255 filed on Dec. 12, 1974 now abandoned.
