BACKGROUND OF THE INVENTION
This invention concerns the fixing of poles, stanchions or the like, either permanent or temporary such as light poles, sign poles, power poles, or flag poles to the ground in a manner providing great stability with minimum of time, effort and expense.

- SUMMARY OF THE INVENTION
Heretofore, the conventional method for firmly planting a post or stanchion in the ground has been to dig a hole, place the post into the hole and then pack soil, crushed stone, or concrete around the post portion within the hole. This is a time consuming excavation and refill procedure which often does not produce the desired stability in that material has to be packed into the excavated hole from which the more firm, original packed soil has been removed.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention provides a method and mechanism for anchoring a pole in the ground without having to excavate the soil, wherein an anchor section is provided and screwed into the ground, and wherein the pole is then affixed to the upper portion of the anchor section which has been left in the ground.
The invention will be further understood from the following description and drawings wherein the structural portions in the various figures are preferably of steel and are not drawn to scale or actual proportions and are intended to elucidate the inventive concepts involved, wherein in accordance with 35 U.S.C. 112 the best mode of practicing the present invention is clearly described, and wherein:
FIG. 1 is a partially sectioned elevational view of the present pole section and anchor section in assembled upright mounted position;
FIG. 2 is a cross-sectional view taken along line 2-2 in FIG. 1 with portions broken away for clarity;
FIG. 3 is a view of the anchor section affixed to a conventional power auger attachment of a Skid Steer machine by way of an adapter means and in position to be screwed into the ground;
FIG. 4 is a view as in FIG. 1 and further showing a pole and its second segment of a connector means in dotted outline in an on-the-ground initial position wherein the first and second segments are connected by a pin to form a hinge;
FIG. 5 shows an inwardly fluted variation of the threaded portion of the anchor section;
FIG. 6 shows an outwardly fluted variation of the thread means; and
FIG. 7 is a perspective view of an auger attachment to a Skid Steer power drive.
Referring to the drawings with particular reference to the claims hereof, the present ground mounted pole construction generally comprises an elongated ground anchor section 10 and an elongated pole section 22. Anchor section 10 has a proximal end portion 12, a distal end portion 14, and a longitudinal axis 16. Thread means 18 of any form or pitch is provided on said distal end portion and is adapted to be forcibly screwed into the ground. A first segment 20 of a connector means is provided on said proximal end portion 12.
Pole section 22 has an upper end portion 24, a lower end portion 26, and a longitudinal axis 28. A second segment 30 of a connector means is provided on said lower end portion and is constructed substantially the same as segment 20. These first and second segments when connected together provide a hinge means generally designated 32 whereby when the anchor section has been screwed into the ground to a desired level, e.g., at or above ground level, and with the pole section lying on the ground or other surface, the first and second segments can be connected to form the hinge means 32 and the pole section can be hoisted by hand or machine by pivoting on the hinge means to an upright position. A fastening means such as bolts 34 mounted thru bolt holes 21 and 23 and nuts 36 are engageable with the segments 30 and 20 of the pole and anchor sections for securing these sections together in a desired upright position. It is noted that shims may be used between the contact surfaces of the plates 20 and 30 to adjust the planes 17 and 19 respectively thereof and the posture or verticality of the pole, however, such is typically not required where care is taken in the operation of the power auger machine.
The anchor section 10 preferably is in the form of a conventional auger 38 which is adapted to connect to the motor output shaft 40 (FIG. 3) of a power auger or power drill as is readily commercially available as an attachment on a Skid Steer, front loader, or other such earth moving equipment. It is noted that the only modification of such an auger attachment which applicant employs is shown in FIG. 3 wherein an adapter means generally designated 44 comprises an adapter plate 46 which is substantially identical to plate or first segment 20 of the anchor section and is provided with a hub 48 into which the end of said output shaft 40 is inserted and pinned by bolt 50 or the like.
The construction of hinge means 32 can be conventional wherein a bearing member 54 is welded or otherwise formed on first segment 20 and wherein bearing segments 56 are welded or otherwise formed on second segment 30. A hinge pin or bolt 58 of any construction is removably mounted thru the bearing segments and preferably is provided with a handle means 60 to facilitate its removal from the hinge means after segments 20 and 30 are bolted together or otherwise firmly fastened together.
In accordance with the present invention, the auger member can be inwardly fluted as at 42 or outwardly fluted as at 52 in or on spindle 53 as in FIGS. 5 and 6 and the pitch of the flutes or threads or the blades of a conventional auger can be widely varied as long as the power means 40 can be regulated to screw the anchor section into the ground rather than simply pounding it into the ground. Further in this regard, the auger attachment must be operated in a manner to screw the anchor section into the ground rather than to excavate a hole. This is accomplished by maintaining adequate downward pressure on the anchor section during its rotation to prevent lifting of the soil upwardly by rotation of the auger.
Referring to FIG. 7, the auger adapter means 44 shown in FIG. 3 is employed and the structures numbered the same. The output or drive shaft 40 is powered typically by an hydraulic motor 41 connected to the hydraulic system of the Skid Steer and carried by an adapter structure 43 which is configured to be latched to the face plate of the Skid Steer or other work vehicle or machine.
It is noted that one of the many advantages of the present invention is that it can be employed to remove posts or the like which have been screwed into the ground, without the need for digging out packed fill dirt, concrete, crushed stone or the like. This is particularly advantageous where temporary poles such as light poles or power poles at construction sites are needed.
The invention has been described in detail with particular reference to preferred embodiments thereof, but it will be understood that variations and modifications will be effected with the spirit and scope of the invention.
