Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to fencing systems and, more
particularly, is concerned with a portable fencing system and the
components therefor which enable quick and easy setup and removal.
2. Description of the Prior Art
Rotational grazing is a pasture management technique that divides a
particular pasture into smaller paddocks for grazing of the pasture by
livestock and horses in a controlled manner. It is known to use fencing
systems for this purpose. The fencing systems must contain the animals'
grazing activities to the defined area for a short amount of time, which
keeps them from inflicting damage to the grass. Once a particular paddock
has been appropriately grazed the animals are moved to another paddock
which allows for the just grazed paddock to quickly and efficiently
recover and be ready for the next grazing cycle.
Rotational grazing is beneficial to both the animal and the pasture. The
animal does not have to graze down to the roots where there is lower
nutritional value and/or higher concentrations of fructans (grass
"sugars") and where it may take in bacteria that may be harmful. Since the
pasture is never over-grazed, the grass stays healthier and more
efficiently produces the roughage that the animal needs. The result is a
significant reduction in the acres of pasture required per animal and an
improvement in the nutritional quality of the feed the pasture produces.
The more intense the pasture management, the shorter the grazing cycle will
be and the more paddocks a pasture will require. This creates a need for
fencing systems to accommodate the temporary containment of the animals
into smaller areas and their movement between these areas. The use of a
permanent fencing system for this type of pasture management will congest
the field with a large maze of fencing and make it very difficult for the
farmer or rancher to use tractors and implements for the conditioning and
maintenance work he has to do to maintain the pasture. Permanent fencing
systems would also severely restrict the manager's ability to respond to
varying conditions within the pasture which may dictate the need to define
grazing areas that do not fit the existing arrangement of the permanent
fencing system.
The inventor herein envisions that the ideal system is a portable fencing
system that can be quickly and easily set up to define a small grazing
area and then removed and set up at another grazing area, used to make
corridors for the efficient movement of animals, and used to otherwise
manage the number and location of animals on the grazing areas. Such
portable fencing system would give the pasture manager flexibility in
providing for efficient grazing and recovery of the pasture. Thus, in
order for rotational grazing to be optimized and labor intensity
minimized, the portable fencing system needs to be quick and easy to set
up, securely anchored to the ground so that it will stay in place, and
require few or no tools to install and remove it.
An example of a prior art portable fencing system is disclosed in U.S. Pat.
No. 5,649,690 to Kilmer. The Kilmer system utilizes a plurality of
portable fence post support assemblies each having a post for supporting a
number of wires, a base member configured for placement lengthwise on the
ground for supporting the post thereabove in an upright orientation, an
angled brace attached to and extending between the post and base member,
and a plurality of anchoring devices in the form of an auger and/or spikes
mounted through and extending below the base and into the ground. While
the Kilmer system appears to be a step in the right direction, it appears
to fall far short of having the characteristics of an ideal portable
fencing system as outlined above. The Kilmer fence post support assemblies
seem rather bulky, cumbersome and awkward to handle and thus would not be
likely to enable a user to be able to quickly and easily set up and take
down such fencing system.
Consequently, a need exists for an innovation which will overcome the
inadequacies of the prior art fencing systems and more nearly have the
characteristics of an ideal portable fencing system as outlined above.
SUMMARY OF THE INVENTION
The present invention provides a portable fencing system and components
therefor that satisfy the aforementioned need and more nearly meet all
characteristics of the ideal portable fencing system. The portable fencing
system of the present invention and the components used therein are
strong, stable and durable and enable quick and easy setup and removal by
only requiring shallow or no soil penetration to provide the needed
anchorage of the system to the ground so as to stay in place and without
the use of tools.
Accordingly, the present invention is directed to a portable fencing system
useful for forming a barricade or corridor arrangement. The portable
fencing system comprises: (a) a winch corner fixture removably anchorable
on a ground segment for providing one end of a barricade or corridor
arrangement along a side of an area adjacent to the ground segment; (b) a
corner post fixture removably anchorable on another ground segment for
providing an end of the barricade or corridor arrangement along the side
of the area adjacent to the ground segments; (c) at least one spacer post
locatable between and spaced from the winch corner fixture and the corner
post fixture and removably attachable on another ground segment along the
side of the area adjacent to the ground segments; and (d) at least one
length of fence wire storable on the winch corner fixture and extendable
therefrom so as to extend between the fixtures and past the spacer post,
the winch corner fixture and corner post fixture having means for securing
the fence wire thereto, the spacer post having means for engaging the
fence wire.
The present invention also is directed to a portable fencing system useful
for forming an enclosure arrangement. The portable fencing system
comprises: (a) a winch corner fixture removably anchorable on a ground
segment for providing one corner of an enclosure arrangement about an area
adjacent to the ground segment; (b) a plurality of corner post fixtures
removably anchorable on other ground segments for providing other corners
of the enclosure arrangement about the area adjacent to the ground
segments; (c) a plurality of spacer posts spaced from one another and
locatable between and spaced from the winch corner fixture and the corner
post fixtures and removably attachable on still other ground segments for
providing side portions of the enclosure arrangement between the corners
thereof and about the area adjacent to the ground segments; and (d) at
least one length of fence wire storable on the winch corner fixture and
extendable therefrom so as to extend between the fixtures and past the
spacer posts, the winch corner fixture and, each of said corner post
fixture having means for securing the fence wire thereto, the spacer posts
having means for engaging the fence wire.
The present invention further is directed to a winch corner fixture useful
in a portable fencing system. The winch corner fixture comprises: (a) a
main support frame having at least three mounting portions angularly
displaced from one another about a central vertical axis of the main
support frame; (b) means for securing portions of a fence wire to the main
support frame; and (c) a plurality of at least three spaced apart leg
members each pivotally mounted to one of the three mounting portions of
the main support frame such that the leg members can be set up in a tripod
configuration about the central vertical axis of the support frame with
the leg members angularly displaced from one another about the central
vertical axis at the same angular displacements of the three mounting
portions of the support frame from one another; and (d) a winch assembly
supported on the main support frame above the three mounting portions
thereof. The winch corner fixture further comprises a plurality of at
least three ground anchor stakes each attached to an end of one of the leg
members and adapted to be inserted into a ground segment by stepping
thereon. The attaching means is a plurality of brackets attached to the
main support frame adjacent to the three mounting portions thereof and
adapted for securing a portion of the fence wire to a selected one of the
brackets.
The present invention still further is directed to a corner post fixture
useful in a portable fencing system. The corner post fixture comprises:
(a) a post member; (b) a pair of brace members; and (c) a pair of support
brackets each separate from the other and independently adjustably mounted
on the post member between opposite ends thereof, each of the brace
members being pivotally mounted to one of the support brackets such that
the brace members are angularly displaced from one another about the post
member and each can be extended outwardly and downwardly at an acute angle
relative to the post member. The corner post fixture further comprises a
pair of the ground anchor stakes each attached to an end of one of the
brace members and adapted to be inserted into a ground segment by stepping
thereon.
These and other features and advantages of the present invention will
become apparent to those skilled in the art upon a reading of the

DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and particularly to FIG. 1, there is illustrated
an exemplary embodiment of an enclosure barrier arrangement of the
portable fencing system of the present invention, generally designated 10,
shown having a typical rectangular configuration. However, it should be
understood that the portable fencing system 10 can be employed to provide
almost any size and shape of an enclosure barrier around an area or a
corridor or line barricade along a side of an area. The typical enclosure
barrier arrangement of the system 10, such as that shown in FIG. 1,
includes at least one winch corner fixture 12, a plurality of corner post
fixtures 14, a plurality of spacer posts 16, and at least one fence wire
18. The typical line barricade or corridor arrangement of the portable
fencing system 10 of the present invention, that would be similar to one
side of the rectangular enclosure barrier arrangement of FIG. 1, includes
a winch corner fixture 12, usually a corner post fixture 14 but not
necessarily if a suitable end connection structure is otherwise available,
a plurality of spacer posts 16, and at least one fence wire 18. In forming
both the enclosure and barricade or corridor arrangements, each of the
winch corner fixture 12, corner post fixtures 14 and spacer posts 16 are
removably anchorable to the ground generally without the use of tools. The
term "ground" or "ground segment" is used herein in a generic sense to
include any type of surface or substrate.
Referring to FIGS. 1 to 3, the winch corner fixture 12 basically includes a
main support frame 20, a plurality of at least three spaced apart leg
members 22, a plurality of at least three ground anchor stakes 24, and at
least one winch assembly 26. As best seen in FIGS. 2 and 2A, the main
support frame 20 of the winch corner fixture 12 includes at least three
mounting portions 28 and means attached thereon about which to wrap the
ends of the fence wires 18 such as in the form of three fence wire anchor
clasps or brackets 30. The mounting portions 28 preferably, although not
necessarily, are in the form of structural channels having inverted
U-shaped configurations which preferably, although not necessarily, are
about equally angularly displaced from one another about a central
vertical axis V of the support frame 20. The fence wire anchor brackets 30
are mounted at respective outer end 28A of the mounting portions 28. The
main support frame 20 further includes an attachment member 32 such as in
the form of an annular washer that overlies and bridges and is rigidly
attached to inner ends 28B of the mounting portions 28 so as to help
fixedly tie the three mounting portions 28 together. The attachment member
32 also may define a central mounting hole 34 therethrough at the central
vertical axis V of the support frame 20. The fence wire anchor brackets 30
are used for tying off the ends or portions of the fence wires 18.
Each of the leg members 22 of the winch corner fixture 12 has an upper end
22A and a lower end 22B. The leg members 22 at their upper ends 22A are
inserted through open bottoms of the mounting portions 28 of the main
support frame 20 behind the fence wire anchor brackets 30 and are hingedly
or pivotally mounted to the mounting portions 28 by suitable fasteners 36
inserted through alignable holes 22C, 28C defined in the leg members 22
and the mounting portions 28. The pivotal leg members 22 can thus be
pivoted toward one another so as to be held next to each other for
convenient carrying and storage or pivoted away from one another until
they abut against stops 38 defined by central portions of the fence wire
anchor brackets 30 for setting the leg members 22 in a tripod
configuration. In such a configuration, the leg members 22 are displaced
from one another about the central vertical axis V of the support frame 20
at the same angles as the mounting portions 28 of the support frame 20 are
displaced from one another. When the leg members 22 are set up, the
particular angles they will make with the ground and central vertical axis
V of the support frame 20 depends upon the locations of the holes 28A in
the mounting portions 28 of the support frame 20 relative to the stops 38
of the anchor brackets 30. Given the particular location shown in FIG. 2A,
the leg members 22 when set up will extend outwardly and downwardly at
about a 45.degree. angle from the central vertical axis V of the support
frame 20 and relative to the ground.
As best seen in FIGS. 2 and 2B, each of the ground anchor stakes 24 of the
winch corner fixture 12 has a relatively straight stake portion 40 and a
tubular sleeve portion 42 attached at one end of the stake portion 40 for
mounting over the lower end 22B of one of the leg members 22 of the winch
corner fixture 12. The stake portion 40 preferably, although not
necessarily, is disposed at about a 90.degree. angle in relation to a
longitudinal axis A of the tubular sleeve portion 42 and thus of the leg
member 22. Each stake portion 40 is insertable into the ground for
securing the respective leg member 22 in place on the ground. When the
winch corner fixture 12 is to be installed, the leg members 22 are spread
outward against their respective stops 38 (which extends them outward at
about 45.degree. angles from the central vertical axis V) and the fixture
12 is set on top of the ground. The inward 900 orientation of the stake
portions 40 of the ground anchor stakes 24 relative to the leg members 22
makes it easy for the installer to step on the lower ends 22B of the leg
members 22 above the downwardly extending stake portions 40 and then use
his or her body weight to force the stake portions 40 into the ground. The
greatest strength is achieved when one of the leg members 22 is oriented
to the inside of the fence enclosure arrangement at an angle halfway
between the angle at which the fence wires 18 will meet at that corner.
This way when the fence wire 18 is tightened it will cause the inside leg
member 22 to go into compression, which means it is being forced into the
ground so it is not in danger of coming out because the ground is very
strong in compression. The two leg members 22 located outside the
enclosure arrangement will then be in tension at the lowest possible level
of force, because tension forces are the hardest to anchor in the soil.
However, when achieving maximum strength is not necessary, it is best to
place all three leg members 22 of the fixture 12 outside of the enclosure
arrangement with two of the leg members 22 disposed adjacent to and
outside of the fence wires 18 meeting at the corner of the enclosure
arrangement. This placement of the leg member 22 eliminates the chance of
an animal striking, pawing, stepping on or otherwise encountering the leg
members 22. The approximate 900 orientation of the anchor portions 40 of
the ground anchor stakes 24 with the respective leg members 22 is what
gives maximum holding power in the soil because it causes the anchor
portions 40 to try to "plow" (shear) their way through the soil instead of
simply being pulled out. Soil can hold the stake much better in shear than
it is able to hold a stake in tension. This is especially true in pastures
where the root system of the grass significantly strengthens the soil's
resistance to shearing forces.
The winch assembly 26 of the winch corner fixture 12 includes a support
bracket 44, a crank handle 46, and a winch reel or spool 48. The support
bracket 44 is formed in a generally U-shaped configuration by a pair of
L-shaped bracket portions 50 which are placed together and stationarily
mounted to the support frame 20 by a fastener 52 inserted through the
mounting hole 34 of the attachment member 32 of the support frame 20 and
bottom holes 56A of the bracket portions 50 which are alignable with one
another and with the mounting hole 34 of the attachment member 32. The
winch spool 48 is supported between the bracket portions 50 of the
U-shaped support bracket 44 on a shaft portion 46A of the crank handle 46
which extends through top holes 50B of the bracket portions 50. The winch
spool 48 is thus mounted for undergoing rotation relative to the support
bracket 44 using a handle portion 46B of the crank handle 46 to turn the
crank handle 46 and the winch spool 48. The winch spool 48 is thus
stationarily mounted over the shaft portion 46A of the crank handle 46 and
is rotatable therewith for taking up and paying out the fence wire 18 on
and from the spool 48. While the winch spool 48 is shown mounted by the
support bracket 44 for rotation about a horizontal axis, it should be
understood that the support bracket 44 could be modified to support the
winch spool 48 for rotation about a vertical axis. Also, the support
bracket 44 could be modified to support a pair of the winch spools 48 each
on one of a pair of crank handles 46 mounted one above the other on the
modified support bracket.
Most arrangements of the system 10 will require at least one winch corner
fixture 12 because it provides a limited length of the fence wire 18 based
upon the capacity of the winch spool 48 with the type of fence wire 18
being used. If the proposed enclosure barrier or barricade arrangement
will be longer than the length of fence wire 18 that can be stored on the
winch spool 48, a sufficient number of additional winch corner fixtures 12
will need to be included in the arrangement to supply the system 10 with
the desired length of fence wire 18. These additional winch corner
fixtures 12 can be placed on the corners or in line, wherever is deemed
most appropriate for the particular arrangement. The fence wire anchor
brackets 30 on the respective winch corner fixtures 12 can be used to tie
off the end of the fence wire 18 from the previous winch spool 48 and
continue on with the fence wire 18 from the next winch spool 48.
Referring to FIGS. 1 and 4, 5, the corner post fixture 14 basically
includes a post member 54, a pair of separate support bracket 56, a pair
of brace members 58, a pair of the ground anchor stakes 24 (the same as
used on the leg members 22 of the winch corner fixture 12), a step bracket
anchor stake 60, and at least one and preferably a pair of wire securing
devices 62 in the form of adjustable clips. The post member 54 of the
corner post fixture 14 has an upper end 54A and a lower end 54B. The
support brackets 56 of the corner post fixture 14 are secured to the post
member 54 at stationary locations intermediate between the upper and lower
ends 54A, 54B thereof. The support brackets 56 each have a substantially
U-shaped configuration. Each of the brace members 58 of the corner post
fixture 14 is pivotally mounted by a fastener 64 through alignable holes
66, 68 in an upper end 58A of the respective brace member 58 and in a
respective one of the support brackets 56 such that the brace members 58
can be extended outwardly and downwardly at a suitable angle, such as a
45.degree. angle, in relation to the post member 54 and displaced at a
suitable angle, such as 60.degree., from one another. The support brackets
56 are independently rotatable on the post member 54 so that they can be
separately relocated horizontally about and vertically on the post member
54 to ensure that both brace members 58 independently of one another can
be inserted in the ground and will hold the post member 58 in an upright
orientation.
Each of the ground anchor stakes 24 of the corner post fixture 14 has the
relatively straight stake portion 40 and the tubular sleeve portion 42
attached at one end of the stake portion 40 for mounting over the lower
end 58B of the respective one of the brace members 58. The stake portion
40 is disposed at about a 90.degree. angle in relation to the longitudinal
axis B of the tubular sleeve 42 and thus of the brace member 58. The stake
portion 40 is insertable into the ground for securing the brace member 58
in place on the ground. The step bracket anchor stake 60 has a straight
stake portion 70 and an angled step portion 72 both attached together in a
substantially L- or T-shaped configuration, and a tubular sleeve portion
74 attached at one end of the step portion 72 for mounting to the lower
end 54B of the post member 54. The angled step portion 72 of the anchor
stake 60 is adapted to receive the installer's foot thereon for forcing
the stake portion 70 thereof into the ground. Each of the adjustable clips
62 is mounted to the post member 54 for holding the fence wire 18 on the
corner post fixture 14.
On a straight-line barricade arrangement, if some appropriate stationary
structure is not available a corner post fixture 14 can be used to serve
as the anchor for the end of the fence wire 18, whereas on enclosure
arrangements, a corner post fixture 14 is placed at every "corner" point
where the fence wire 18 will change directions. The corner post fixture 14
and its anchorage components are designed to withstand the lateral forces
caused by the tensioned fence wire 18 when it changes direction at that
corner. To install the corner post fixture 14, the post member 54 is
positioned where required by the type of enclosure barrier arrangement or
barricade arrangement being erected. Using the step bracket anchor stake
60, the installer forces the stake portion 70 into the ground. The two
brace members 58 are then positioned outside of the boundary of the
arrangement at an orientation approximately halfway between the angle that
would be made by the fence wires 18 if they were extended past the corner.
The support brackets 56 should be stationarily positioned along the length
of the post member 54 so that the brace members 58 once installed to the
ground will hold the post member 54 in the upright orientation. This
assures that the brace members 58 will be placed in tension when the fence
wire 18 is tightened and the post member 54 will be forced down against
the ground so it will not be in danger of coming out. As was the case with
the winch corner fixture 12 discussed earlier, the post member 54 in
compression and the two brace members 58 in tension with the 90.degree.
angle orientation of the stake portions 70 to the brace members 54 is what
provides maximum holding power in the soil because it causes them to try
to "plow" (shear) the stakes through the soil instead of simply being
pulled out.
Referring to FIGS. 1, 6 to 8, the spacer post 16 includes a post backbone
76 having an upper end 76A and a lower end 76B, a plurality of spaced
apart wire guiding devices 78, a ground anchor stake 80, and a step
bracket 82. Each guiding device 78 is either an integral part of the post
backbone 76 as seen in FIG. 6 or is a separate part that is adjustably
mounted to the post backbone 76 as seen in FIGS. 7 and 8. The guiding
device 78 can have a slot 84 defined therein for receiving the fence wire
18 therethrough. In the post 16 of FIG. 6, the slot 84 preferably is
angled to allow the fence wire 18 to be easily placed into the guiding
device 78 when the fence wire 18 has no tension and not to allow the fence
wire 18 to come out from the guiding device 78 when the fence wire 18 has
tension thereon. In the posts 16 of FIGS. 6-8, the slot 84 of the guiding
device 78 is configured for receiving the fence wire 18 so as to allow the
fence wire 18 to slide horizontally (longitudinally), but not vertically,
relative thereto. The guiding devices 78 can take either of the forms
shown in FIG. 6, in FIGS. 7, 7A and 7B or in FIGS. 8 and 8A. In FIG. 6,
the guiding device 78 is stationarily attached to the post backbone 76. In
FIGS. 7, 7A and 7B, the guiding device 78 is a clip 86 stationarily
secured to the post backbone 76 by a double wedge 88. In FIGS. 8 and 8A,
the guiding device 78 is another clip 90 stationarily secured to the post
backbone 76 by a set screw 92. In either form, the guiding devices 78 hold
the fence wires 18 at the desired separation.
The ground anchor stake 80 of each spacer post 16 has a generally straight
configuration and is preferably a continuation of the lower end 76B of the
post backbone 76 and extends longitudinally inline with the post backbone
76 so as to be insertable into the ground for securing the post backbone
76 in place on the ground. The step bracket 82 is mounted to the post
backbone 76 adjacent to the lower end 76B thereof and, as seen in the
embodiments of FIGS. 7 and 8, has a spike 94 attached to and extending
downward from an outer end 82A of the step bracket 82. The step bracket 82
receives thereon the installer's foot to force the ground anchor stake 80
and outer spike 94 into the ground.
Since the spacer posts 16 are not subject to high lateral forces, they can
stand alone without additional bracing being needed. A number of the
spacer posts 16 are placed at intervals along the length of the straight
sections of the fence wire 18 between the winch corner fixture 12 and/or
corner post fixtures 14. The function of the spacer posts 16 is to
maintain a desired separation between strands of a multiple-wire enclosure
or barricade and to keep the sag in the wire 18 to an acceptable minimum.
Preferably, an extra spacer post 16 is provided on either side of the
winch corner fixture 12 to immediately establish the desired fence wire
height above the ground and multi-strand spacing for the system 10.
Referring again to the enclosure arrangement of FIG. 1, at least one and
preferably a pair of strands of the fence wire 18 of the system 10 pass
between and are secured to the corner post fixtures 14 and spacer posts
16. The strands of fence wire 18 extend from the winch spool 48 of the
winch corner fixture 12 and are tied off on the fence wire anchor brackets
30 of the support frame 20 of the winch corner fixture 12. The fence wire
18 can be any available round wire, cable, rope or flat tape. The term
"wire" is used herein in a generic sense to include any of these types.
For containment of animals the choice is usually some form of
electrifiable wire or rope. The electrification of the wire, in addition
to preventing the animals from pushing through and escaping the
containment, also keeps the animals from pressing casually against the
portable fencing system 10 causing forces that the fencing system 10 is
not designed to withstand.
Referring to FIGS. 9 to 17, there are illustrated several different
mounting point devices 96 designed to assist the winch corner fixture 12
and corner post fixture 14 of the portable fencing system 10 in overcoming
the weaknesses of different ground segments having characters that lack
the characteristics normally desired to accommodate the set up of the
system 10. Each of the mounting point devices 96 includes a support base
member 98 and penetration means 100 extending downwardly from the base
member 98 for penetrating the particular ground segment. After the
penetration means 100 on the base member 98 is placed into the ground
segment by using one's body weight, a mallet or the like, the stakes 24 of
a winch corner fixture 12 or a corner post fixture 14 is inserted through
a middle hole 102 in the support base member 98 and also placed into the
ground segment. In such manner, the mounting point device 96 enhances and
extends the anchorage normally provided by the respective fixture 12, 14.
FIGS. 9 to 11 show an embodiment of the mounting point device 96 having a
base member 98 in the form of an angle bracket and penetration means 100
in the form of a pair of spikes fixed to and extending in parallel
relation from the opposite ends of the bracket 98 for use in the
installation of the system 10 in weak soil conditions, such as sandy
loams, freshly disced fields, soils with little root structure, pebbly
mountainside and rock soils, very wet and soft sods, etc. FIGS. 12 to 14
show another embodiment of the mounting point device 96 having a base
member 98 in the form of a rigid plate and penetration means 100 in the
form of a rigid flat spade-like blade for use in the installation of the
system 10 in sand conditions. FIGS. 15 to 17 show still another embodiment
of the mounting point device 96 having a base member 98 in the form of a
rigid plate and penetration means 100 in the form of a rigid flat hoe-like
blade for use in the installation of the system 10 in muddy conditions.
Each of the embodiments of the mounting point devices 96 also has a rope
handle 104 attached to the base member 98 to facilitate easy extraction of
the device 96 from the particular ground segment once its use has ended.
Referring to FIGS. 18 to 20, there is illustrated a surface mounting
bracket 106 designed to assist the setup of the winch corner fixture 12
and the corner post fixture 14 of the portable fencing system 10 on
surfaces where penetration is either not possible or permitted, such as
concrete or paved surfaces or driveways, arenas, floors, hard pan, shelf
rock, hard campgrounds, etc. The bracket 106 has a lower member 108 which
lies on the surface and an upper member 110 which is pivotally mounted at
one end 110A to the lower member 108 near a corresponding one end 108A
thereof. A short tube 112 is fixedly mounted in an upright orientation at
the one end 108A of the lower member 108 of the surface mounting bracket
106. The stake 70 of the fixture 14 clips into the short tube 112 of the
surface mounting bracket 106. The lower and upper members 108, 110 of the
bracket 106 have turned up other ends 108B, 110B with respective centered
holes therethrough for receiving the stakes 24. FIG. 18 shows different
extended conditions of the upper member 110 relative to the lower member
108 of the surface mounting bracket 106. It is required that sand bags or
other weighted objects (not shown) be applied on the surface mounting
bracket 106 to stabilize the respective fixture 12, 14. FIG. 19 shows the
lower and upper members 108, 110 of the surface mounting bracket 106 in a
retracted condition.
Referring to FIGS. 21 to 23, there is illustrated a surface mounting block
114 designed to assist the setup of the spacer posts 16 of the portable
fencing system 10 on the surfaces mentioned earlier where penetration is
either not possible or permitted. The block 114 preferably, but not
necessarily, is rectangular in configuration and has a central hole 116
therethrough for receiving the ground anchor stake 80 of the spacer post
16 so as to hold the post 16 in an upright orientation as shown in FIG.
21. One material useful for constructing the block 114 so that it will
have a weight suitable for performing the desired function described above
is recycled plastic lumber.
The portable fencing system 10 of the present invention as now fully
described hereinabove is designed for use on all traversable surfaces of
ground ranging from pure sand to solid rock. It should be understood that
by merely drilling three small shallow holes in hard surfaces, such as
rock, the spike points of the stakes 25 of the winch corner fixture 12 can
be inserted into the holes and the fixture 12 thereby held and anchored on
the hard surface without the use of any accessory, such as the
above-described surface mounting bracket 106.
The installation of the portable fencing system 10 to provide the enclosure
barrier arrangement of FIG. 1 can be accomplished by the performance of
the following steps:
(1) The "tripod" or winch corner fixture 12 is placed in a desired
location, setting its leg members 22 at the desired angle. With his or her
heel on the ground, the installer pushes each ground anchor stake 24 into
the soil with the ball of his or her toot. If multiple corner post
fixtures 14 are to be used, roughly place them and "step" them in at this
time, also.
(2) Holding the fence wire 18 by a nonconductive handle (not shown) that
can be provided at the end of the fence wire 18, the installer walks
across or around the area to be fenced or enclosed, pulling the fence wire
18 behind. Sufficient slack must be left in the wire or sufficient wire
must be left on the winch spool 48 to later tighten and wrap the fence
wire 18.
(3) The installer then hooks the nonconductive handle onto the end point of
the portable fence system 10. If one is forming an enclosure, this end
point will be the tripod or winch corner fixture 12 itself, using one of
the wire wrap anchor brackets 30 at the base of the spool 48. The handle
permits the use of the portion of the wire extending from the spacer post
16 next to the winch corner fixture 12 as an entryway to the enclosure.
(4) The installer next steps in the line or spacer posts 16 at the desired
locations along the fence line.
(5) The pair of fence wires 18 are then inserted through the securing and
guiding devices 62, 78 on all corner post fixtures 14 and spacer posts 16.
One should start at the tripod or winch corner fixture 12 and work towards
the end point of the portable fencing system 10 so as to prevent
accidental twisting of the two strands of fence wire 18.
(6) At the tripod or winch corner fixture 12, the pair of fence wire
strands 18 are pulled to the tension desired. Some slack in the fence line
is recommended. At this point, lots of slack hanging off the spool 48 is
okay and in fact helpful.
(7) Holding on to both wire strands 18, the installer now lays one wire 18
across one of the wire wrap anchor brackets 30 on the tripod or fixture
12. Using the excess slack that is hanging off the spool 48 (and not the
taught fence wire), the installer now wraps about three times around the
wire wrap anchor bracket 30.
(8) The installer concludes the steps by applying electricity to the fence
wire 18 from a suitable electrical power supply source.
In conclusion, the main features and advantages of the portable fencing
system 10 of the present invention can be summarized as follows.
(1) The fencing system 10 is highly portable, it requires no tools to
install and it has components that are made of lightweight materials, are
compact, and easy to transport or store. It is easy to set up, utilizes a
shallow penetration of the earth which generally permits installation
using the installer's body weight alone, and yet it demonstrates
exceptional anchorage strength in the ground.
(2) The corner formed by the multiple leg members 22 with the winch spool
48 centered on top of the fixture 12 is advantageous in that the
orientation of the winch spool 48 to the angled leg members 22 assures
that the anchorage forces will be equally divided between the leg members
22 for maximum resistance to separation from the ground. Three leg members
22 are the minimum required; other embodiments could use more legs to gain
additional ground anchorage strength.
(3) The main support frame 20 of the fixture 12 maintains the proper
orientation and pivoting of the three leg members 22 as well as provides
anchorage brackets 30 for the ends of the strands of fence wire 18.
(4) The orientation of the stakes 24 on the leg members 22 is advantageous
in how each stake 24 is caused to act like a "plow" under load which takes
advantage of the superior shear strength found in pasture soils with good
grass root systems. Whereas the anchor portion 40 of the anchor stake 24
shown in the illustrated embodiment is of a simple round configuration and
of a relatively short length, it should be understood that other shapes
and longer lengths can be used for the many different soil conditions to
which it may be exposed.
(5) The configuration of the corner post fixtures 14 with their arrangement
of corner brace members 58 outside of the enclosure arrangement of the
fence system 10 whereby fence tension forces place these brace members 58
in tension to fully utilize the advantages of the anchorage feature noted
in (4) above. If the brace members 58 were, instead, merely oriented in
the direction of the fence wire 18 and placed into the interior of the
enclosure arrangement, they would be put in compression and would cause
the vertical corner post member 54, unless securely anchored, to be
leveraged upward and out of the ground.
The portable fencing system 10 of the present invention, as described in
detail above, can be used for a multitude of functions including, but not
limited to, the following: (1) providing enclosures or barriers for the
containment of livestock, people or vehicles; (2) defining barricades or
corridors for the preventing or directing of movement of livestock, people
and vehicles; (3) defining boundaries for sports fields, arenas or crime
scenes; (4) providing dividers for sports fields or arenas; (4) providing
portable paddocks; (5) capture assist for animals; and (6) for testing out
various fencing strategies before building permanent fence.
It is thought that the present invention and its advantages will be
understood from the foregoing description and it will be apparent that
various changes may be made thereto without departing from the spirit and
scope of the invention or sacrificing all of its material advantages, the
form hereinbefore described being merely preferred or exemplary embodiment
thereof.
