Definitions

  • the present invention is related to an anchor device for supporting a replaceable elongate member such as a post in the ground.
  • the post may be a guide post for traffic or be used for carrying a road sign. It has been estimated that some 70 million guideposts, or delineators, are used on Australian roads. Most of these guideposts are made of timber. Such timber guideposts require holes to be dug in the ground in order to install the guideposts correctly in position. A correct excavation of such holes and the subsequent correct positioning of the timber guideposts requires a great deal of skill and many man hours. Furthermore, once such a timber guidepost is accidentally hit by a vehicle it is usually broken and rendered useless.
  • a traffic guidepost has a tubular anchor having a closed lower end which is in the form of a flattened wedge which is driven into the ground by a suitable driver.
  • the anchor has an open upper end into which is installed a tubular post which engages with the anchor in a telescopic manner.
  • the post is retained in the anchor by appropriate fasteners.
  • the post had to be lubricated before installation in the anchor and slid downwardly in the anchor a considerable distance to make attachment between the anchor and the post more secure.
  • One disadvantage of this conventional arrangement is that the post extends upwardly above the ground and is likely to be sheared off if impacted by a vehicle which means that the entire assembly of post and anchor will need replacement.
  • a steel anchor is used having a pointed end which is driven into the ground which supports an upwardly extending post which is riveted to a plate like top part of the anchor.
  • the invention in one aspect provides a method of installation of a post in the ground which includes the steps of: (i) forming a hole in the ground; (ii) locating a ground anchor in the hole having one or more internal sockets wherein the or each internal socket is substantially flush with ground level; and (iii) inserting a post into the internal socket(s) whereby said post is retained therein with a major part of the post extending above ground level whereby flexing of the post upon impact may occur about a hinge point corresponding to ground level.
  • the hole may be formed by an excavating tool such as a spade or use of a suitable driving tool or alternatively may be formed by hammering the ground anchor into the ground until the ground anchor is substantially flush with the ground. This is suitable when the ground is relatively soft. It therefore will be appreciated from the foregoing that steps (i) and (ii) can be carried out sequentially or simultaneously.
  • the post In relation to step (iii) the post may be retained within the internal socket of the ground anchor by interference fit or alternatively by use of a latch or projection engaging an aperture in the ground anchor or the post.
  • a ground anchor having a body with one or more ground penetration members and at least one internal socket and retaining means for retaining a post within said at least one internal socket which is retaining means located adjacent said at least one internal socket whereby in use a post may extend into said at least one internal socket to engage the retaining means.
  • the internal socket of the body of the ground anchor may be elongate and thus may have a cross sectional shape in the form of a shallow rectangle wherein one pair of opposed surfaces of the rectangle have a much greater width than another pair of opposed surfaces of the rectangle.
  • the socket may be in the shape of a shallow channel corresponding to a V, U or C wherein the socket has a pair of opposed surfaces of shallow corresponding curvature which are of far greater width than another pair of opposed surfaces which are relatively narrow in width in comparison.
  • This embodiment is particularly useful because the posts to which the ground anchor of the invention are particularly directed have a corresponding shape to the internal socket and thus may be plate like having a pair of opposed broad surfaces and a pair of opposed edges which are restricted or narrow in width.
  • the body of the ground anchor comprise a pair of spikes separated by a spacer plate wherein each spike is provided with a socket or groove of channel configuration whereby edges or flanges of the post having a similar cross sectional shape may engage with and move or slide within a corresponding socket or groove.
  • the retaining means of the ground anchor may comprise a slot or aperture in a side wall of the body which in use may engage with a latch or projection of the post to retain the post within the internal socket of the ground anchor.
  • the retaining means may comprise a latch or projection of the body engaging with a corresponding slot or aperture of the post.
  • the body may also have at least one ground penetrating member or a pair of ground penetrating members.
  • the ground penetration member may comprise a sharpened bottom edge portion of the body preferably having a wedge type configuration.
  • the ground penetration member(s) may comprise one or more ground penetration spikes extending downwardly and outwardly from the body in use.
  • FIG 1 is an exploded perspective view of the ground anchor of the invention in the appropriate orientation to engage with a mating post
  • FIG 2 is a similar view to FIG 1 wherein the ground anchor is provided with a different retaining means to that shown in FIG 1
