Abstract
A ground anchor rod drilled into soil is held in place by a generally rectangular stabilizer having various side thicknesses of about 2-1 cm from a top to a bottom portion and a front and backside having a width of about 20 cm. The front face contains multiple depressions over its entire surface for receiving soil. The backside has two parallel spaced. apart vertical protrusions for enclosing a portion of the ground anchor rod when the stabilizer is hammered into the ground juxtaposed to the ground anchor rod. The stabilizer is made from a high strength plastic such as ABS and can withstand loads in excess of four thousand pounds.
Description




BACKGROUND OF THE INVENTION




The present invention relates to a ground anchor. More specifically, it refers to a stabilizer used in conjunction with a ground anchor rod for stabilizing the anchor rod in the soil.




A frequent problem is the movement of house trailers, tents and other structures in high winds caused by the pulling free of anchoring posts which have been set in soil. In addition, there is a common problem with fence posts where the bottom portion of the posts move in the soil causing the entire fence to shift and either collapse or become askew. The prior art is replete with methods attempting to stabilize fence posts as shown in U.S. Pat. Nos. 598,003; 624,724 and 672,625. U.S. Pat. No. 897,787 describes a device for stabilizing a shore anchor. U.S. Pat. No. 903,944 describes a spiraling ground anchor device supporting a post and U.S. Pat. No. 911,504 describes a land anchor which has a spiral auger secured to the lower end of a hollow shank. U.S. Pat. No. 1,214,679 describes a fence post anchor which is fined within a lower flange portion of the post. A lower portion of the post has slits which move out around the anchor. Additional patents relating to fence post anchors are U.S. Pat. Nos. 1,764,207; 2,799,369; 3,011,597; and 4,939,877. U.S. Pat. No. 3,032,149 describes a clothes dryer support. The support is a tubular post adapted to be imbedded into the ground. A broad bracing member is connected to an upper end of the tubular post. The vertical post is passed through a sleeve to retain the tubular post in an upright position. U.S. Pat. No. 4,052,827 describes a ground anchor having winged segments that receive an anchoring devices through a hollow interior portion. U.S. Pat. No. 4,756,128 describes a beach anchor having a rod with a bottom end driven into beach sand and an upper end having a handle and a right angle plate surrounding the rod and stabilizing it in the sand.




Although the prior art describes many anchoring devices, the hunt continues for a device that will stabilize ground anchors at high loads such as in excess of four thousand pounds. The present invention solves this problem and differs from the teachings of the prior art by contemplating a plastic plate that can be pounded into the ground juxtaposed to a ground anchor rod.




SUMMARY OF THE INVENTION




A ground anchor rod stabilizer of this invention is a generally rectangular member having multiple thicknesses from a narrow bottom end portion through a thicker top end portion. The front face portion of the ground stabilizer has multiple oval shaped depressions covering its face for receiving soil upon being hammered into the ground. A back side portion of the ground anchor rod stabilizer has a pair of parallel spaced apart vertical protrusions which guide the stabilizer alongside a vertical rod or post which has been pounded into the ground as a ground anchor. The ground anchor stabilizer of this invention is made of high strength plastic and can withstand loads in excess of four thousand pounds. It is an object of this invention to prevent ground anchor rods or posts from pulling free from soil at high loads by providing a method and apparatus for stabilizing the ground anchor at loads exceeding four thousand pounds. These and other objects and aspects of the present invention will be better understood when the following detailed description of the preferred embodiments is read in conjunction with the appended drawing Figures.

SPECIFIC DESCRIPTION OF THE PREFERRED EMBODIMENT




With reference to

FIG. 1

, the ground anchor rod stabilizer of the present invention is generally designated by reference numeral


10


. The ground anchor rod stabilizer


10


is generally rectangular in shape but has a chamfered bottom end


12


with slanted side portions shown by wails


14


and


16


contained within a first bottom section


18


having a first thickness. A second higher section


20


has a second thickness. A third higher section


22


has a third thickness and a fourth highest section


24


has a fourth thickness. The thickness from the first section to: the fourth section varies from about 2-1 cm. A top edge


26


is flat and is used as a surface for pounding the ground anchor rod stabilizer


10


into the ground. Multiple oval depressions


28


substantially throughout the stabilizer front face


30


provide a means for receiving soil and adding to the stabilization of the ground anchor rod


48


. The front and back face have a width of about 20 cm, but it can vary from 15-30 cm. The prepared length of the front and back face is about 60 cm, but this can vary depending on the length of the ground anchor and the type of soil employed. Alternating side depressions


32


have a narrower depression then items


28


. Multiple horizontal support rods


34


in the third section


22


provide added strength to the ground anchor stabilizer


10


. Additional support is found in the fourth highest section


24


with horizontal support members


36


.




As seen in

FIG. 2

, the depressions


32


and


28


are open to a depth of approximately ⅘ the thickness of the ground anchor stabilizer. The support members


34


fill a portion of the depressions


28


in the middle of section


22


. The backside


40


of the ground anchor rod stabilizer


10


has parallel outward projections


42


that extend vertically substantially along the middle portion


44


of the ground rod stabilizer


10


. The projections


42


form a channel


46


to receive ground anchor rod


48


. A bottom portion


50


of the projections


42


is tapered to promote easy insertion into the ground. The ground anchor rod stabilizer


10


as shown in

FIG. 4

is pounded into the ground so that it projects above the ground surface


52


a short distance. The ground rod


48


has a ring


54


at the top which can be attached to a rope or a cable connecting the ground anchor rod to a tent or a trailer. In the case of a use for supporting fence posts, the ring


54


would not be present. As seen in

FIG. 4

, the bottom portion of the rod


48


has an auger


56


fixably attached to promote insertion of the rod


48


into the ground. The stabilizer


10


is usually a plastic member made from a high strength plastic or can be high strength aluminum, or steel and is hammered vertically into soil adjacent where an auger rod has been drilled into the soil. The projections


46


surround a portion of the anchor rod


48


. The front face


30


receives soil as the stabilizer


10


is pounded into the ground.




This stabilizer


10


resists removal from the soil by a pulling force of over four thousand pounds. The preferred plastic employed for the stabilizer is ABS. However, other high strength plastics as well as aluminum or steel can be used to make the stabilizer


10


.




The ground stabilizer


10


is preferably molded in an injection molding process as is well known in the prior art.




Accordingly an invention has been disclosed in terms of a preferred embodiment thereof which fulfills each and every one of the objects of the present invention as set forth herein above and provides a new and useful ground anchor stabilizer of great novelty and utility.




Of course, various changes, modifications and alterations in the teaching of the present invention may be contemplated by those skilled in the art without departing from the intended spirit and scope thereof.




As such, it is intended the present invention only be limited by the terms of the intended claims.
