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.
