Fence Post Repair Device
Background of the Invention
The present invention relates to the field of fence repair. Many fences are
built using wooden
fence posts that are anchored in the ground using cement fill around the
post's below-ground
lower portion. The installation process is based on using an auger to drill a
cylindrical hole in
the earth that is filled with concrete while the fence post is held vertically
in the hole. When the
concrete has hardened, the fence post is ready for use to support the fence
that is attached to
the fence posts.
Over a period of time the fence post may suffer from rot or some other type of
damage at or
near to the lower portion of the fence post, allowing the fence to lean
because the damaged
fence post will no longer stay vertical or support any lateral loads. In order
to replace the
damaged fence post, it is necessary to dig up the concrete around its base,
which is a difficult
task at best and will probably require dismantling the fence around the fence
post in question.
Commercial alternatives exist, basically manufactured stakes that are driven
into the ground,
which attach to the lower portion of the remaining fence post, but none of
them allow for the
fact that the concrete with the lower portion of the fence post remains in the
way of the stake.
A better solution that can be used to repair the fence post in situ, without
any digging up of
concrete or dismantling of the fence is the subject of this invention.
Summary of the Invention
It is the object of this invention to provide a device that can be used to
repair a damaged fence
post in situ, without any digging up of concrete or dismantling of the fence.
The fence post repair device consists of three main components:
1) The spike that is driven into the ground to provide the stability to the
device.
2) The horizontal portion that connects to the spike and joins it to the
vertical portion.
This horizontal portion provides the offset that allows the spike to miss the
concrete

Date Regue/Date Received 2022-08-27
holding the fence post base. This horizontal portion also provides a surface
for striking
with a hammer to drive the spike into the ground.
3) The vertical portion that attaches the device to the upper portion of the
damaged
fence post using screws or other types of fasteners.
In general terms these three components have the following characteristics:
1) The spike is between 2 to 4 feet long and is tapered (or not) to provide
easy entry into
the ground while providing resistance to movement due to its bearing on the
soil
around it. The spike is preferably made of metal, most likely steel, but other
materials
are not precluded. Attachment to the horizontal portion is made through
welding,
screwing, or other bonding methods.
2) The horizontal portion is between 3 and 12 inches long and is stiff enough
and strong
enough to prevent permanent distortion during installation. It too is
preferably made of
metal, most likely steel, but other materials are not precluded. In the
embodiment
shown here, it is made from a section of channel with reinforcing brackets and
it is
attached to the vertical portion through welding, screwing, or other bonding
methods.
3) The vertical portion is between 6 and 36 inches long and is stiff enough
and strong
enough to prevent permanent distortion during installation. It too is
preferably made of
metal, most likely steel, but other materials are not precluded. In the
embodiment
shown here, it is made from a section of channel with bolt holes and it is
attached to the
fence post through screwing, or other bonding methods.
During installation of the fence post repair device it as expected that the
following steps will be
followed:
For installing the fence post support device using concrete.
1) The process starts by digging a hole beside the existing concrete around
the base of the
broken post,
2) The fence post support device is the bolted to the upper portion of the
broken post,
3) The broken post upper portion is then braced in a vertical position,

4) Wet concrete is then poured into the hole around the portion of the fence
post support
device,
5) The concrete is the allowed to set,
6) The bracing is removed,
7) The broken post is now repaired.
For installing the fence post support device by driving it into the ground.
1) The process starts by locating the fence post support device next to the
broken post location,
2) Then the fence post support device is driven into the earth,
3) Then the fence post support device is bolted to the post using lag bolts,
4) The broken post is now repaired.

With reference to FIG. 11A, 11B, and 11C, a comparison between the cross
sectional shape
possibilities of the channel, 105, of FIG. 11A, the X cross section, 106, of
FIG. 11B, and the H
cross section, 107, of FIG. 11C is made. The comparison is based on the
surface area in contact
with the ground when the cross sectional shapes, 105, 106, and 107 are driven
into the ground.
Assuming that the channel cross section, 105, is 4 inches by 1 inch, the X
cross section, 106, is 4
inches by 4 inches and the H cross section, 107, is also 4 inches by 4 inches,
then the surface
contact for a 1 inch length is as follows:
Cross Section Area ¨ Square Inches
Channel Cross Section, 105 12
X Cross Section, 106 16
H Cross Section, 107 24
Since the pull out force is proportional to the contact are between the cross
section and the
ground, it is clear that H cross section, 107, is superior to both the X cross
section, 106, and the
channel cross section, 105.
With reference to FIG. 12 a flow chart, 110, for installing the fence post
support device using
concrete is shown. The process starts by digging a hole beside the existing
concrete around the
base of the broken post, 111, the fence post support device is the bolted to
the upper portion
of the broken post, 112, the broken post upper portion is then braced in a
vertical position,
113, wet concrete is then poured into the hole around the portion of the fence
post support
device, 114, the concrete is the allowed to set, 115, the bracing is removed,
116, and the
broken post is now repaired, 117.
With reference to FIG. 13 a flow chart, 120, for installing the fence post
support device by
driving it into the ground is shown. The process starts by locating the fence
post support device
next to the broken post location, 121, then the fence post support device is
driven into the
8

earth, 122, then the fence post support device is bolted to the post using lag
bolts, 123, and the
broken post is now repaired, 124.
