2 Claims. (Cl. 18931) This invention relates to ground anchors and particularly to such an anchor having at least one fluke movable from an inoperative ground entering position into an operative anchoring position.
Stakes and pegs are used for a wide variety of purposes and while the problems presented by their use are the same, they are best illustrated in connection with guying trees and large poles. For such uses, relatively small and easily positioned anchoring means are desired if adapted to withstand the heavy dislodging strains placed upon them.
The general objective of this invention is to provide ground anchors well adapted to meet the above indicated requirements. In accordance with the invention, a ground anchor comprises a body having its ground entering end pointed and provided with an opening which so receives the arm of a fluke as to enable the fluke to swing from an inoperative ground entering position into an operative anchoring position at an angle to the body thus to ensure that the grip of the ground anchor becomes more secure in response to dislodging pulls thereon.
In the accompanying drawings, there is shown an illustrative embodiment of the invention from which these and other of its objectives, novel features, and advantages will be readily apparent.
In the drawings:
Fig. 1 is an end view of a ground anchor in accordance with the invention.
Fig. 2 is a partly sectioned side elevation of the anchor with its flukes operatively positioned, and
Fig. 3 is a similar view with the fiukes inoperatively positioned.
In the drawings, the ground anchor is shown as comprising a stake or body 5 of right angular section having its ground entering portion terminating in a point 6 and with both walls provided with a transverse slot 7, each axially spaced from the other.
2,771,163 Patented Nov. 20, 1956 If, however, the ground anchor is subjected to dislodging strains, the flukes 8 move towards their operative position shown in Fig. 2 as being approximately at right angles to the stake 5 with the arm part 9 of each fluke extending through a slot 7 and with the intermediate part 11 in parallel with the inner surface of a stake wall.
It will be noted that each fluke 8 has a reinforcement 12 whose end 13 butts against the wall below the slot 7 for that fluke.
While guy ropes or wires may be otherwise attached to ground anchors in accordance with the invention, each stake wall is shown as having a hole 14 to receive such guy lines, and the end by which it is driven into the ground is preferably in the form of a relatively fiat point 5.
From the foregoing, it will be appreciated that ground anchors in accordance with the invention are well adapted to meet production requirements as well as those of service.
What I therefore claim and desire to secure by Letters Patent is:
l. A ground anchor comprising a body of right angular sec-tion having its ground entering end in the form of a point, at least one Wall of said body having a transverse slot, and a fluke, said fluke including a supporting arm including a first part, extending in the same direction as said fluke and connected thereto, a terminal part extending in the same directions as the fluke, and an intermediate part disposed at right angles to said other parts and extending upwardly when said first part is in said slot and said fluke is substantially normal to one side of said body, the length of said first part being such that when said fluke is in said position said intermediate part is parallel with and in contact with the other side of said stake, and the length of said intermediate part being such that when the fluke is parallel with and in contact with said one side of said stake the terminal part is parallel with and in contact with said other side of said stake.
2. A ground anchor comprising a body having its ground entering end in the form of a point, said body having a transverse slot, and a fluke, said fluke including a supporting arm including a first part, extending in the same direction as said fluk and connected thereto, a terminal part extending in the same direction as said fluke, and an intermediate part disposed at right angles to said other parts and extending upwardly when said first part is in said slot and said fluke is substantially normal to one side of said body, the length of said first part being such that when said fluke is in said position said intermediate part is parallel with and in contact with the other side of said stake, and the length of said intermediate part being such that when the fluke is parallel with and in contact with said one side of said stake the terminal part is parallel with and in contact with said other side of said stake.
