Definitions

  • the present invention relates to an anchor apparatus and particularly to a ground anchor apparatus for anchoring an object such as a park bench or a tree root-ball.
  • a ground anchor is used to secure an object at a particular location, to prevent theft or vandalism or to prevent the object being dislodged, by high winds for example.
  • Objects such as benches, children's play equipment, litter bins, root-balled trees and outdoor seating are amongst those that might require ground anchoring.
  • a commonly used ground anchor is a metal device with an attachment point for a shaft and an aperture for engaging a drive rod. The drive rod is used to drive the anchor and shaft mechanically into the ground. Once the anchor is in position, a pulling force is applied to the shaft to move the anchor into a locked orientation so that the anchor can apply a restraining force to an aboveground object secured to the shaft.
  • These traditional anchors are formed from metal so that they can withstand the drive forces required to drive the device into the ground.
  • an anchor apparatus for use underground comprising an anchor body having a drive aperture, the anchor body being moveable between a drive position and a locked position, wherein the anchor body comprises a generally conical nose portion and one or more deflecting ribs.
  • the anchor apparatus further comprises an attachment fin.
  • the anchor body further comprises an oblique flange at an end opposite to the nose portion.
  • the apparatus further comprises a drive collar for receiving a drive rod.
  • the drive collar is a hollow, truncated cylindrical element having a tapered base and a truncating plane oblique to the base.
  • the anchor body comprises four deflecting ribs approximately uniformly spaced with respect to the generally conical nose portion.
  • the anchor body is formed from plastics.
  • the anchor body is formed from biodegradable plastics.
  • Figure 1 is a perspective view of an embodiment of an anchor apparatus in accordance with the present invention
  • Figure 2 is a cross sectional view of the embodiment of Figure 1;
  • Figure 3 is a perspective view of an embodiment of a drive collar in accordance with the present invention.
  • Figure 4 is a partial cross-sectional view of the embodiment of Figure 3 in use with a drive rod;
  • Figure 5 is cross-sectional view of the embodiment of Figure 1 , in use, in a drive orientation with the drive collar of Figure 3;
  • Figure 6 is a cross-sectional view of the embodiment of Figure 5 in a locked orientation.
  • Figures 1 and 2 show a ground anchor apparatus including an anchor body 10 having four deflector ribs 11, a drive aperture 12, an oblique flange 15 and an attachment fin
  • Anchor body 10 is a generally cylindrical element with a rounded conical segment at one end and drive aperture 12 at an opposite end.
  • Deflector ribs 11 are arcuate elements that project radially outwards from anchor body 10 and intersect at a point adjacent the rounded conical segment of body 10 to form a pointed nose section
  • Ribs 11 are equally spaced around the circumference of anchor body 10 ( Figure 2).
  • Attachment fin 13, positioned on the cylindrical part of anchor body 10, has an aperture for connection to a linkage shaft, as will be described below.
  • FIG 3 shows a drive collar 16 engagable with flange 15 of anchor body 10.
  • Drive collar 16 is a hollow cylindrical element having a tapered end 17, an obliquely- truncated end 19 and a longitudinal cut-away portion 18. Cut-away portion 18 prevents interference between drive collar 16 and a linkage shaft attached to the apparatus in use.
  • a drive rod 20 is insertable through drive collar 16, as illustrated in Figure 4. In use of the anchor apparatus, drive rod 20 is inserted through drive collar 16 into drive aperture 12 such that obliquely-truncated end 19 of drive collar 16 engages with oblique flange 15 of anchor body 10 and tapered end 17 of drive collar 16 engages with drive rod 20.
  • a linkage shaft 21 is connected to attachment fin 13 ( Figure 5).
  • Drive rod 20 and drive collar 16 are then connected to anchor body 10, via drive aperture 12.
  • a drive force is applied to drive rod 20 to mechanically drive nose portion 14 of the anchor into the ground.
  • drive rod 20 and linkage shaft 21 are positioned parallel to the longitudinal axis of anchor body 10. Deflector ribs 11 guide anchor body 10 in a generally straight direction through the ground. If anchor body 10 contacts any underground obstructions, such as a sewer pipe, conical nose portion 14 and deflector ribs 11 deflect the apparatus away from the obstruction.
  • linkage shaft 21 is approximately perpendicular to the longitudinal axis of anchor body 10 (figure 6).
  • the linkage shaft is then connected to an aboveground object to secure the object in place.
  • Deflector ribs 11 provide an increased surface area and hence an increased force-loading area. Therefore, ribs 11 enable the apparatus to withstand greater pulling forces from the secured object.
  • nose section 14 and oblique flange 15 are such that, during installation, drive forces are distributed evenly throughout the whole of anchor body 10. Consequently, the structural integrity of the apparatus is preserved, even at high drive forces.
  • Drive collar 16 acts to further spread drive impact forces evenly throughout the apparatus. Effective force distribution means that, even when formed from plastics, the apparatus of the present invention can withstand high drive forces.
  • Plastic has the advantages that it has a low surface resistance, it does not conduct electricity and it is unlikely to cause significant damage to underground utilities.
  • a plastic ground anchor is also cheap to produce, particularly in the case of an injection moulded anchor.
  • the apparatus of the present invention can be formed from biodegradable plastics thereby avoiding the need to remove the anchor, with possible damage to the roots of surrounding plants.
  • Traditional ground anchors on the other hand, must be formed from metal in order to withstand the high drive forces required to drive traditionally- configured anchors into the ground.
