Definitions

  • This invention relates to an anchor for a variety of applications for use in various soil types such as for guy ropes for tents, beach umbrellas and other beach items, and also for other situations where it is desired to anchor an object in soil which has little or no cohesion.
  • an anchor includes a plate having flexible lines attached at opposite sides, the plate being adapted to be forced into the ground with one of the opposite sides foremost, whereafter the line attached to the leading side line can be pulled to cause rotation of side against the soil or sand until the desired resistance to further rotation of the plate is established, the line attached to the leading side being attachable to the object required to be anchored; and the line attached to the other, trailing side being arranged to remain above the surface of the soil for access to a withdrawing pull when desired.
  • an anchor for use in anchoring an article in soil, comprising: a substantially flat plate having flexible lines attached adjacent to opposite leading and trailing sides, the plate being adapted to be forced into the soil with the leading side foremost, whereafter the line attached to the leading side can be pulled to cause rotation of the leading side against the soil to cause the soil to be compacted against the rotation of said leading side until a desired resistance to further rotation is established, the line attached adjacent to the leading side being adapted to be attached to the article to be anchored; and the line attached adjacent to the trailing side being arranged to remain above the soil for access to a withdrawing pull when desired.
  • a sliding hammer or other device may be provided to assist the insertion of the plate into the soil and the plate may be pointed at its side of entry for easy insertion.
  • the upper line attached to trailing side may have a ring at its extremity so that an upward pull may be exerted when the plate anchor is required to be removed.
  • the pull will be generally vertical and in most cases will merely involve a reverse rotation of the plate against soil which has not been compacted and which, in fact, has been loosened by the rotation of the plate in the anchoring situation.
  • the sliding hammer may be used to assist the pull and may, if necessary, be used a lever.
  • a plate anchor includes a plate having a formation adapted to receive a line, the formation being located at or near the leading edge of the anchor when inserted into ground for the anchor to be pulled in a direction in which the soil resistance is increased, the other end of the line being attachable to an object desired to be anchored.
  • the plate may also include a second formation (at or near the trailing edge), which may be a simple orifice so that a second line may be attached when it is desired to remove the anchor.
  • the first formation may take the form of a loop and the line may be a wire.
  • a plate anchor 10 has one side 12 pointed and has a line 14 attached near the point of the leading side and line 16 attached at the opposite trailing side.
  • the plate is inserted into the soil as shown in Fig. 2, which can be assisted by a sliding hammer 18, for example, and when at the desired depth, the line 14 is pulled as shown in Fig. 3, thus causing rotation of the lower side 12, as shown by the arrow 20.
  • Other similar devices for inserting the anchor plate may also be used.
  • the trailing side may also rotate, compacting soil at the trailing side to some degree also.
  • the soil 22 in front of the rotating portions of the anchor becomes compacted due to the rotation of the plate and this compaction is sufficient to provide adequate anchorage.
  • the article requiring to be anchored is attached to the spring clip 24, or other fastening means.
  • the other line 16 connected to the trailing side is pulled and the sliding hammer 18 may be used for this purpose as shown in Fig. 4, or in Fig. 5, where it is used as a lever.
  • the plate anchor of the invention has particular utility in cohesionless soils and sands including beach sand.
  • the present invention is particularly useful for supporting fences, trellises for fruit growing, power line poles, aerials and virtually anything which needs permanent or semi-permanent support.
  • a plate 30 has a loop 32 adjacent its pointed leading end 34.
  • the loop 32 is located on a thickened portion 36 of the plate 30.
  • a wire, rope or other line (not shown) is attached to the loop on one end, and the object to be anchored on the other end.
  • the plate may be driven point first into the ground by means of a hammer in a vertical or near vertical state, and the wire connected to the leading side is then pulled so that the plate pivots on the edge remote from the point and the soil is then compacted in front of the movement of the plate.
  • a hole 38 may be provided adjacent the trailing side for attachment of a second line such as line 16, so that if, or when the plate is required to be removed, the second line attached to the plate through the hole 38 can be used for pulling the plate vertically upwards.
  • a second line such as line 16
