Definitions

  • a ground anchor device A ground anchor device
  • the present invention refers to ground anchoring devices, which are to be screwed into the soil.
  • the part of the device extending above a ground plate can be differently shaped, suited to a variety of uses.
  • the important part of the invention pertains to the helical member retaining the device in position.
  • a general desire is that the screwing into the soil should occur with a small input of power, but the ground engaging portion must possess sufficient rigidly to withstand the lateral forces, which may be applied to the portion of the device projecting above ground.
  • a device is characterized in that the helical member is formed as an open helix, and that at least one stay is attched to the plate in a position to support said helix.
  • the helix may be attached directly to the plate and at least two stay rods, preferably located diametrically opposite to each other are attached to the plate, within the helix, extending downwardly across at least two windings thereof and attached thereto.
  • the helix, as well as the stay rods may then made from profile bars having a substantially semicircular cross-section, or consist of a flat bar being wound into a helix, or alternatively a tube being cut along a helical line, and then expanded longitudinally.
  • the stay may alternatively be formed as a tubular member to the edge portion of which, remote from the plate, the helix projects.
  • the stay tube is then preferably adjacent to the plate provided with at least one opening for forcing out soil.
  • FIG. 1 shows a fence post, provided with a helical member according to the invention
  • Figures 2 and 3 show detail views of elements attached to the post for holding barbed wire or other fencing material
  • Figure 4 is an end view, seen from below of the helical member
  • Figure 5 shows an anchoring device adapted to receive a bar or the like to be maintained in upright position
  • Figure 6 shows an anchoring device carrying an eye-bolt to be used for staying or tieing purposes.
  • Figure 1 shows a fence post 10 having a screw member 11 according to a first embodiment of the invention, and connec ted to the post stanchion 12 by means of a plate 13, which, in use, will rest upon the ground.
  • the plate is preferably circular and has a slightly vaulted form.
  • the stanchion 12 is preferably formed from a square-section pipe, and is at suitable distances above the ground provided with brackets 14 to carry fence wire or the like.
  • the bracket is shown on a larger scale in Figure 3.
  • the upper end of the pipe is closed by a removable stopper 15, the shape of which is better shown in Figure 2.
  • the stopper 15 may be made of plastic, and has two upwardly directed ears 17. Each of those is at one of its vertical edges provided with a slot 18.
  • the slots are directed in opposite directions, so it is possible to fit a fence wire between the ears, and then straighten it, so it will be jammed into the slots 18. It will thus not be necessary to fix the wire to the post.
  • brackets 14 The shape of brackets 14 is better shown in Figure 3.
  • each bracket there are two notches 19 suited to receive barbed wire, and two .slots 20 suited to receive rope or wire for temporary fencing purposes.
  • the slots 19 and 20 are, to each side of the post member 12, turned in opposite direction, so it is possible to stretch a vire over one bracket, and below an adjacent bracket, and so on while simultaneously changing from inside the posts to outside thereof. In such a manner a satisfactory retension of the wire is obtained to a row of fence posts without any tying or other manner of locking.
  • the helical member is here formed as an open helix, i.e. it has no core, it is just a bar wound around an imaginary, cylindrical, core.
  • the helix is formed by a bar 22 having about semi circular cross-section, which is attached directly to plate 13.
  • the open helix will offer a low reistance only, during the screwing into the soil , but it will have a low capacity to withstand forces acting sidewardly upon the post member.
  • two stays 23 are attached to plate 13, within the open helix and extending downwards over a few windings of the helix, to which they are attached.
  • the stays 23 are also preferably manufactured from a bar having a semi-circular cross-section. Two stays are preferably located diametrically opposite each other, within the helix. Due to heir shape they will only add insignificantly to the resistance during the screwing down operation, but they will brace the helix in a very satisfactory manner.
  • Figure 5 shows a modified embodiment of a ground anchor device, which here includes a short length of tubing 25 provided with a suitable number of locking screws 26.
  • the short tube may be used for receiving a pole carrying for instance a drying rack, or a garden umbrella, or an outdoor Christmas tree.
  • the helical member is formed in a slightly different manner from the previous one.
  • a tube 27 is attached to the plate 13 and the helix 28 issues from the edge of the tube remote from the plate.
  • the tube 27 is the stay which takes care of possible lateral forces acting upon the pole. When the helix works its way downwards soil will be forced up into the tube, and this is therefore provided with at least one opening 29, just below plate 13, where excess soil may be squeezed out.
  • the helix 28 may, as with the embodiment according to Figure 1, consist of a flat bar having doout semi-circular cross-section, but it can also be formed directly from the tube.
  • tubes 25 and 27 may be integral and have circular cross-section.
  • the combined tube is passed through a hole in the plate and welded thereto.
  • the lower end of tube 27 can be cut along a helical line,and the helix 28 is there formed by expanding the cut tube part longitudinally.
  • Figue 6 shows a further, modified embodiment.
  • the portion above the plate is here formed as an eye bolt 30 , which may be used for various staying purposes, and the helical member 31 is formed by a flat bar being wound along an helical path, and welded to the lower face of the plate 13.
  • Within the helix there are two stays 23, which are welded to the plate and to some of the adjacent windings of the helix.
  • the stays may, as with the embodiment according to Figure 1,advantageously be formed from pieces of bars having a semi-circular cross-section.
  • All components, i.e. posts and other upwardly directed members, the plate and the helical member are made of steel and welded together, and may be galvanized or anti-corrosion treated in any suitable manner.
  • the helical members may be modified in many ways, and as is evident from the drawings, there are many fields of use for devices according to the invention. It is for instance possible to mount arcuate transoms between parallel rows of posts of the type shown in Figure 1 or Figure 5, to carry tarpaulins or the like to temporarily provide shelters for goods to be stored out of doors.

Abstract

Dispositif d'ancrage au sol comprenant une plaque (13), qui lors de l'utilisation reste sur le sol, un etai (12, 25, 30) ou similaire s'etendant a partir d'une face de la plaque ainsi qu'un organe helicoidal (11) pouvant se visser dans le sol. L'organe helicoidal a la forme d'une helice ouverte (22, 28, 31) et la plaque possede au moins un support vertical (23, 27) servant a renforcer l'helice, laquelle, par elle-meme, ne possedant pas de noyau, n'aurait pas une rigidite laterale satisfaisante. Les supports peuvent etre formes par de courtes barres (23), de preference de sections transversales semi-circulaires, soudees a la plaque (13) a l'interieur de l'helice (22, 31) et s'etendant vers le bas sur au moins deux enroulements de l'helice, pour y etre soudees. Selon une variante, le support peut etre forme par une certaine longueur de tube (27) a l'extremite duquel et a une certaine distance de la plaque sort l'helice (28). Le tube (27) est muni de preference d'au moins une ouverture (29) permettant la sortie du sol que l'helice fait penetrer a l'interieur du tube.
