DETAILED DESCRIPTION
The ground anchor shown in the drawings comprises an elongate body generally indicated at 10 with a lower end 11 on which is mounted an auger flight 12. Elongate body has a longitudinal axis 13 with the flight threaded about that axis so that the flight can be driven into the ground by rotating the elongate body in engagement with the ground. The elongate body comprises a pair of tubes 14 and 15 which lie end to end and coaxial relative to the axis 13. In a preferred embodiment the tubes are of 2 inches outside diameter. At the lower end 11, the lower tube 15 has an end piece 16 inserted which has a lowermost central apex 17 diverging outwardly to a shoulder portion 18 of equal diameter to the outside of the tube 15 and an insert portion 19 engaging into an interior of the tube 15 to hold the end piece16 in place.
The tubes 14 and 15 are interconnected by a cylindrical sleeve 20 which has an outside diameter substantially equal to the inside diameter of the two tubes so as to be a sliding fit in the adjacent ends of those tubes. A
transverse pin 21, 22 interconnects the cylindrical sleeve to each of the tubes.Thus each tube has a transverse hole 23 formed diametrically there across and defining an opening in each side of the tube. The pin a preferred arrangement comprises a 3/4 inch diameter bolt which extends through both of the openings 23 and carries a nut 24 at its outer end to hold the pin 22 in place.
- 2155~04 The tube 14 extends from the cylindrical sleeve 20 to an upper end 24 of the tube 25. Adjacent the end 24 is provided a further transverse pair of holes 23A.
At the upper end 24 is welded a cylindrical nut 26 which is 5 coaxial with the axis 13 and stands upwardly from the top of the tube 14 with a central threaded bore 27 of the nut extending vertically and coaxially of the axis 13.
The ground anchor when assembled further includes a stabilizer assembly 30 comprising a sleeve 31, an end plate 32 at one end of the sleeve 10 and a plurality of wings 33 welded to the outside of the sleeve and extendinggenerally radially outwardly therefrom. In the example shown there are four such wings each of generally triangular shape but it will be appreciated that the number of wings can be reduced or increased in accordance with requirements. A preferred arrangement generally includes three such wings 15 arranged at 120 spacing around the sleeve 31.
Each of the tubes 14 and 15 generally has a length of the order of 4 feet so that the full length of the elongate body 10 is approximately 8 feet.
The flight 12 has a number of turns sufficient so that it's axial length is of the order of 24 inches which provides a high engagement force relative to the 20 ground after the flight is threaded into the ground thus accommodating significant axial loads to the elongate body 10.
The ground anchor when assembled further includes a mounting assembly generally indicated at 40 comprising an elongate threaded rod 41 carrying a nut 42 which is welded to the rod at a predetermined position 25 therealong spaced from a lower end 43 of the rod and an upper end 44 of the rod. The nut 42 can be rotated to engage the threaded rod into the threaded bore 27 so that rotation of the nut drives the threaded rod into the nut 26 until a lower end of the threaded rod engages into the interior of the tube 14.
When the nut 42 engages the plate 32 of the stabilizer assembly, the nut 42 drives the upper plate 32 downwardly thus driving the stabilizer assembly into the ground until the upper plate 32 engages the top of the nut 26.
The mounting assembly 40 further includes a mounting bracket assembly 45 including a mounting bracket 46 of L-shape having an upwardly extending flange 47 and a horizontal base plate 48. On the underside of the base plate 48 is welded a vertical sleeve 49 of square cross section. The lower end of the sleeve is welded to a mounting plate 50 which has a central hole 51 for receiving the threaded rod extending therethrough into the sleeve 49. A nut 52 is threaded onto the threaded rod and abuts against the washer 53 in turn pressing against the mounting plate 50. On the underside of the nut 52 is provided a further washer 54 spacing the nut 52 from a support plate 55. On the underside of the support plate 55 is provided a further washer 56 and a further nut 57. As shown in Figure 2, the base plate 48 is substantially square and the mounting plate 50 is rectangular so that ends of the support plate project outwardly beyond ends of the base plate 48. The support plate 55 is coextensive with the mounting plate 50 and each of the plates 50 and 55 is drilled with aligned openings 58 and 59 for receiving bolts 60 and 61. It will be noted therefore that the weight from the mounting bracket rests upon the nuts 52 and 57 and is transmitted through the plates 50 and 55. In addition upward movement of the mounting bracket is prevented by the clamping of the plate 55 between the nuts 52 and 57 and by interconnection of the support plate 55 with the mounting plate 50 by way of the bolts 60 and 61.
In addition the height of the mounting bracket can be adjusted by rotating the nuts 52 and 57 on the threaded rod thus adjusting the height of the whole mounting assembly relative to the threaded rod. This adjustment increases and decreases the length of the threaded rod within the sleeve 49.
-- 2155~04 In mounting of the ground anchor into the ground, the elongate body 10 is initially supplied in the two separate pieces defined by the tubes 14and 15. With the cylindrical coupling sleeve 20 removed, a handle 66 is engaged with the upper part of the tube 15 by insertion of a pin 67 through 5 the opening 23 transversely of the tube 15 of the upper part of the tube. The handle includes an elongate handle portion 68 extending from an end of the pin 67 coaxially therewith with a length of the handle sufficient to allow manual force in a direction of an arrow 70 to rotate the tube 15 and thus drive the flight 12 into the ground.
When the tube 15 is driven substantially wholly into the ground, the handle 66 is removed and the tube 14 attached to the top of the tube 15.
The handle is then inserted through the opening 23A at the top of the tube 14 and the driving rotation of the elongate body continued until the elongate body is driven into the ground substantially to the top of the elongate body. At this15 time the stabilizer assembly is engaged over the top of the elongate body andthe threaded rod engaged into the nut 26. The threaded rod is then rotated to the drive the stabilizer assembly downwardly to engage the stabilizer assembly into the ground. With the threaded rod thus fully engaged into the nut 26, the threaded rod is supported on the elongate body vertically upwardly therefrom 20 for receiving the mounting assembly as previously described.
Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying 25 specification shall be interpreted as illustrative only and not in a limiting sense.

The tubes 14 and 15 are interconnected by a cylindrical sleeve 20 which has an outside diameter substantially equal to the inside diameter of the two tubes so as to be a sliding fit in the adjacent ends of those tubes. A
transverse pin 21, 22 interconnects the cylindrical sleeve to each of the tubes.Thus each tube has a transverse hole 23 formed diametrically there across and defining an opening in each side of the tube. The pin a preferred arrangement comprises a 3/4 inch diameter bolt which extends through both of the openings 23 and carries a nut 24 at its outer end to hold the pin 22 in place.
- 2155~04 The tube 14 extends from the cylindrical sleeve 20 to an upper end 24 of the tube 25. Adjacent the end 24 is provided a further transverse pair of holes 23A.
At the upper end 24 is welded a cylindrical nut 26 which is 5 coaxial with the axis 13 and stands upwardly from the top of the tube 14 with a central threaded bore 27 of the nut extending vertically and coaxially of the axis 13.
The ground anchor when assembled further includes a stabilizer assembly 30 comprising a sleeve 31, an end plate 32 at one end of the sleeve 10 and a plurality of wings 33 welded to the outside of the sleeve and extendinggenerally radially outwardly therefrom. In the example shown there are four such wings each of generally triangular shape but it will be appreciated that the number of wings can be reduced or increased in accordance with requirements. A preferred arrangement generally includes three such wings 15 arranged at 120 spacing around the sleeve 31.
Each of the tubes 14 and 15 generally has a length of the order of 4 feet so that the full length of the elongate body 10 is approximately 8 feet.
The flight 12 has a number of turns sufficient so that it's axial length is of the order of 24 inches which provides a high engagement force relative to the 20 ground after the flight is threaded into the ground thus accommodating significant axial loads to the elongate body 10.
The ground anchor when assembled further includes a mounting assembly generally indicated at 40 comprising an elongate threaded rod 41 carrying a nut 42 which is welded to the rod at a predetermined position 25 therealong spaced from a lower end 43 of the rod and an upper end 44 of the rod. The nut 42 can be rotated to engage the threaded rod into the threaded bore 27 so that rotation of the nut drives the threaded rod into the nut 26 until a lower end of the threaded rod engages into the interior of the tube 14.
When the nut 42 engages the plate 32 of the stabilizer assembly, the nut 42 drives the upper plate 32 downwardly thus driving the stabilizer assembly into the ground until the upper plate 32 engages the top of the nut 26.
The mounting assembly 40 further includes a mounting bracket assembly 45 including a mounting bracket 46 of L-shape having an upwardly extending flange 47 and a horizontal base plate 48. On the underside of the base plate 48 is welded a vertical sleeve 49 of square cross section. The lower end of the sleeve is welded to a mounting plate 50 which has a central hole 51 for receiving the threaded rod extending therethrough into the sleeve 49. A nut 52 is threaded onto the threaded rod and abuts against the washer 53 in turn pressing against the mounting plate 50.

As shown in Figure 2, the base plate 48 is substantially square and the mounting plate 50 is rectangular so that ends of the support plate project outwardly beyond ends of the base plate 48. The support plate 55 is coextensive with the mounting plate 50 and each of the plates 50 and 55 is drilled with aligned openings 58 and 59 for receiving bolts 60 and 61. It will be noted therefore that the weight from the mounting bracket rests upon the nuts 52 and 57 and is transmitted through the plates 50 and 55. In addition upward movement of the mounting bracket is prevented by the clamping of the plate 55 between the nuts 52 and 57 and by interconnection of the support plate 55 with the mounting plate 50 by way of the bolts 60 and 61.
In addition the height of the mounting bracket can be adjusted by rotating the nuts 52 and 57 on the threaded rod thus adjusting the height of the whole mounting assembly relative to the threaded rod. This adjustment increases and decreases the length of the threaded rod within the sleeve 49.
-- 2155~04 In mounting of the ground anchor into the ground, the elongate body 10 is initially supplied in the two separate pieces defined by the tubes 14and 15. With the cylindrical coupling sleeve 20 removed, a handle 66 is engaged with the upper part of the tube 15 by insertion of a pin 67 through 5 the opening 23 transversely of the tube 15 of the upper part of the tube. The handle includes an elongate handle portion 68 extending from an end of the pin 67 coaxially therewith with a length of the handle sufficient to allow manual force in a direction of an arrow 70 to rotate the tube 15 and thus drive the flight 12 into the ground.
