- FIGS. 15 - 17 An alternate embodiment of a ground anchor 210 for anchoring the post 12 into the ground is illustrated in FIGS. 15 - 17 .
- the anchor 210 is designed to releasably self-lock with the post 12 and permit manual disconnection of the anchor from the post.
- the end of the post 12 that interacts with the anchor 210 must be hollow.
- the anchor 210 is preferably formed entirely from plastic, such as polycarbonate, acrylonitrile butadiene styrene (ABS) or other engineering grade plastics.
- the anchor 210 comprises a central body 212 that is generally hollow and has a shape that generally matches the shape of the post 12 so that the central body 212 fits within the end of the post in close fitting relation therewith.
- the close fit between the body 212 and the interior of the post 12 secures the anchor and the post and prevents excessive relative movement therebetween.
- the central body 212 is generally rectangular in shape so as to match the generally rectangular shape of the hollow end of the post 12 .
- the central body 212 could have other shapes, such as circular or triangular, corresponding to the shape of the post that is used.
- a cylindrical sleeve 214 through the center of the body 212 defines a passage 216 .
- the passage 216 permits a spike or other similar supplemental anchoring member (not shown) to extend through the center of the anchor 210 and into the ground to supplement the anchoring action of the anchor 210 .
- a plurality of ribs 218 extend between the exterior surface of the sleeve 214 and the interior surface of the body 212 to reinforce the sleeve 214 .
- the skirt 220 Surrounding the exterior of the body 212 adjacent the base end thereof is a skirt 220 .
- the skirt 220 includes a first flange portion 222 that extends outwardly from the body 212 , an upwardly extending portion 224 , a second flange portion 226 that extends outwardly from the end of the portion 224 , and a downwardly extending portion 228 .
- a groove 230 is defined between the exterior of the body 212 , the flange portion 222 and the portion 224 , which is angled slightly away from the exterior of the body 212 . In use, the groove 230 receives the end of the post 12 therein, as is illustrated in FIG. 17B.
- the anchor 210 is provided with a pair of integral locking members 232 a , 232 b .
- the locking members 232 a , 232 b are identical to each other, so the construction and operation of only the member 232 a will be described in detail. Referring to FIGS. 15 and 16, it is seen that the exterior of the body 212 is formed with a channel 234 that receives the locking member 232 a .
- the channel 234 extends approximately the entire height of the portion of the body 212 that projects above the flange portion 226 , with the sleeve 214 defining the rear of the channel 234 along the upper end, and with the portion of the channel 234 below the sleeve 214 opening into the interior of the body 210 via a passage 236 .
- the locking member 232 a comprises a locking arm 238 that extends parallel to the channel 234 , with the exterior surface of the arm 238 preferably being generally even or flush with the exterior surface of the body 212 .
- the arm 238 is connected adjacent one end thereof to the sleeve 214 by a connector 240 , whereby the arm 238 is cantilevered so as to permit the opposite end of the arm 238 to resiliently flex.
- the opposite end of the arm 238 is circular in shape and has an enlarged thickness compared to the remainder of the arm 238 (see FIG. 16) so as to form a lock button 242 .
- the lock button 242 is sized to interact with an aperture 244 formed in the post 12 adjacent the bottom end thereof, whereby, in use, the button 242 fits into the aperture 244 when the post 12 and anchor 210 are engaged to lock the post to the anchor.
- the button 242 is generally tapered in thickness, with the thickness increasing from its juncture with the remainder of the arm 238 to the bottom end of the button 242 . The tapering of the button 242 helps the post slide over the arm 232 a as the post and anchor are being connected.
- the anchor 210 further includes a plurality of integral ground engaging spikes 250 which, in use, are intended to be driven into the ground for anchoring the post.
- the anchor 210 includes four integral spikes 250 . It is to be realized, however, that a larger or smaller number of spikes could be used.
- the spikes 250 extend from the bottom of the central body 212 at each corner thereof.
- Each spike 250 is formed from a plurality, preferably four, circumferentially even spaced ribs 252 .
- the ribs 252 are tapered such that the spikes 250 taper from adjacent the body 212 to their distal ends.
- the tapering of the spikes 250 facilitates insertion of the spikes 250 into the ground, with the ribs 252 providing adequate securement once the spikes are driven into the ground. Further, as described above, a spike or other member, if desired, can be inserted through the passage 216 to supplement the spikes 250 .
- the locking members 232 a , 232 b are designed to releasably connect the post 12 to the anchor 210 .
- the end of the post is slid over the body 212 of the anchor, and into the groove 230 until the end of the post 12 engages the flange portion 222 .
- the tapered buttons 242 are pushed inward by the post.
- the resilient return force of the arms 238 force the buttons 242 outward through the apertures 244 , thereby locking the post and the anchor together.
- the buttons 242 must be pushed inward to disengage from the apertures 244 , at which point the post 12 and anchor 210 can be pulled apart.
- One embodiment of the fence strand assembly 14 includes a housing 30 that is slidably connected to the post 12 to permit adjustment of the housing 30 along the length of the post 12 .
- the housing 30 is preferably formed from injection molded plastic, such as polycarbonate, acrylonitrile butadiene styrene (ABS) or other engineering grade plastics.
- ABS acrylonitrile butadiene styrene
- the housing or portions thereof could be formed from a metal material if desired.
- a roll of fence strand material 34 Disposed within the housing 30 in a cup-shaped depression 32 thereof (best seen in FIG. 4) is a roll of fence strand material 34 .
- the fence strand material 34 is illustrated in the figures as being a tape, such as polytape. However, it is to be recognized that other fence strand members, such as wire, rope and other slender fence strand members, could be used as well.
- the fence strand material 34 can be electrified to provide an electric fence system.
- One end of the fence strand material 34 extends through a slot 36 formed in the side of the housing 30 , while the opposite end of the fence strand material 34 is secured to a spindle 38 .
- the spindle 38 includes a plurality of slots 40 therein through which the end of the fence strand material 34 extends such that rotation of the spindle in the appropriate direction causes the fence strand material 34 to be wound onto the spindle.
- the bottom end of the spindle 38 forms a pivot 42 which fits through a hole provided in the bottom of the cup-shaped depression 32 (see FIG. 4 ), with the spindle secured in place by a locking clip 44 engaging with a slot 46 in the pivot 42 .
- a spool 48 is rotatably received at the top of the housing 30 and closes off the cup-shaped depression 32 so that the roll of fence strand material 34 is enclosed within the housing.
- the spool 48 and housing 30 prevent ingress of water, dirt and other contaminants to the roll of fence strand material 34 thereby increasing the reliability and operational life of the fence strand assembly 14 .
- the spool 48 includes a hole therein that receives a correspondingly shaped head 50 on the spindle 38 . As illustrated in the figures, the hole and head 50 are rectangular in shape, although it is to be realized that other shapes, such as triangular, pentagonal or the like, could be used.
- the housing 30 is illustrated in FIG. 4 as having an open bottom. However, the housing preferably cooperates with a housing cover 300 , illustrated in FIG. 21, that closes the bottom of the housing 30 .
- the housing cover 300 has a shape that is complementary to the shape of the open bottom of the housing 30 , and is secured to the housing using screws that extend through bosses 302 on the cover 300 and into threaded boss 304 (shown in FIG. 4) formed on the housing 30 .
- the cover 300 preferably includes a plurality of weep holes 306 to allow drainage of the interior of the housing 30 .
- a crank handle 52 is disposed on, formed on, or otherwise connected to the top surface of the spool 48 .
- the crank handle 52 is sized and shaped so as to permit manual or mechanical rotation of the spool 48 .
- Rotation of the spool 48 causes rotation of the spindle 38 , due to the fit of the head 50 into the spool hole.
- the spool 48 can be rotated via the crank handle 52 , thereby rotating the spindle 38 , to either pay-out (i.e. extend) the fence strand material 34 or wind-up (i.e. retract) the fence strand material 34 .
- a locking mechanism is preferably provided in order to lock the fence strand material 34 and prevent further retraction/extension of the fence strand material 34 .
- the lock mechanism includes a lock lever 54 that is pivotally secured on the housing 30 adjacent the slot 36 to control ingress/egress of the fence strand material 34 through the slot 36 .
- the lock lever 54 includes a pair of pivot pins 56 that snap fit into suitably provided holes in the housing 30 .
- a clamp bar 58 formed on the lock lever 54 forcibly clamps the fence strand material 34 against a wire finger 60 (see FIG. 4) and against the housing 30 , when the lock lever 54 is in the position shown in FIGS.
- a scalloped depression 62 is formed on the lock lever 54 to permit a persons finger(s) to get behind the lever to facilitate pivoting of the lever to an unlock position where the lever 54 projects from the outline of the housing 30 .
- FIG. 22 An alternate embodiment of a lock lever 54 ′ is illustrated in FIG. 22.
- the lock lever 54 ′ which is preferably used with the construction illustrated in FIG. 11, includes a series of projections 59 on the clamp bar 58 ′ enhance the clamping action of the lock lever 54 ′.
- the wire finger 60 discussed above forms one end of a wire 64 that extends beneath the cup-shaped depression 32 as best seen in FIG. 4.
- the opposite end of the wire 64 extends through a slot 66 in the housing 30 and forms a loop 68 .
- the loop 68 permits connection of fence strand material 34 to the housing 30 .
- the housing 30 such as on the bottom of the cup-shaped depression 32 , includes a plurality of wire supports 320 that holds and secure the wire 64 .
- the housing cover 300 in FIG. 21 includes a plurality of wire supports 322 for holding and securing the wire 64 when the cover is mounted on the bottom of the housing 30 .
- a strand connector 70 is connected to the end of the fence strand material 34 .
- the strand connector 70 is preferably formed from a metal, such as stainless steel, or from a suitable plastic material.
- the connector 70 includes a buckle end 72 provided with a series of slots 74 through which the end of the fence strand material 34 is woven like a buckle so that the end of the fence strand material and the connector 70 are securely fastened.
- the opposite end of the connector 70 is formed into a hook 76 which is intended to engage the loop 68 on the wire 64 to connect the end of the fence strand material 34 to an adjacent housing 30 .
- the construction of the connector 70 is particularly suited for use with a tape, such as polytape, as the fence strand material. If the fence strand material 34 is slender, such as wire or rope, an alternate connector that is more suited for connection to a slender fence strand member, but which also is able to connect to the housing, could be used.
- the connector 70 would preferably be formed from metal so that electrical current is transferred from the fence strand material of one housing, through the connector 70 which connects to the loop 68 and into the wire 64 of an adjacent housing which carries the current across the adjacent housing to the finger 60 which in turn is in electrical contact with the fence strand material of the adjacent housing as a result of the clamping action provided by the lock lever 54 . In this manner, electrical continuity can be maintained.
- the connector 70 can be either metal or plastic, and connects to the housing in the manner described or in any other suitable manner.
- An optional gate handle 78 can be provided to facilitate handling of the end of the fence strand material 34 .
- the gate handle 78 is preferably formed of extruded polyvinylchloride (PVC) or other suitable plastic, and includes a channel 80 formed therethrough.
- PVC polyvinylchloride
- the fence strand material 34 slides through the channel 80 and the buckle end 72 of the connector 70 wedges tightly into the channel 80 .
- the gate handle 78 provides a convenient handle by which a user can grasp and hold the end of the fence strand material 34 .
- the fence strand assembly 14 is adjustable along the length of the post 12 .
- the housing 30 is provided with a clamp assembly 82 that defines a shape, corresponding to the shape of the post 12 , to permit clamping engagement of the housing 30 with the post 12 , as shown in FIGS. 14.
- the clamp assembly 82 includes a bolt 84 , a washer 86 and a knob 88 that cooperate in a manner known in the art to tighten and loosen the clamp assembly 82 . Through appropriate rotation of the knob 88 , the clamp assembly 82 is loosened and the fence strand assembly 14 can be adjusted along the length of the post 12 to the desired height.
- a cap 90 fits into and closes off the second end 20 of the post 12 .

- a clamp assembly 82 has been described herein as permitting adjustment of the housing 30 , other means permitting adjustment of the housing 30 could be utilized as well.
- an indexing system including a plurality of indexing holes along the length of the post 12 and an indexing pin inserted through a portion of the housing 30 and into a selected one of the indexing holes could be used.
- the fence post assembly 10 can be used to form an electric fence or enclosure.
- the fence strand material 34 must be constructed so as to permit conduction of electricity.
- the type of tape used can be a bi-polar tape.
- Bi-polar tapes which are generally known in the art, include a hot wire(s) and a ground wire extending along the length thereof.
- the fence strand tape for either non-electric or electric uses, also preferably includes a reflective strand r extending through the center of the tape, as shown in FIG. 12, to indicate the presence of the tape at night when light reflects off of the reflective strand.
- a conducting wire rather than tape, can be used as the fence strand material 34 if desired.
- a suitable type of wire is polywire.
- the use of wire permits a longer length of fence strand material 34 to be used on the spool 48 , as compared to using tape.
- the length of the wire that can be used can be up to about four time greater than the length of the tape.
- the wire 64 is one means that can be used to transfer electricity between fence strands.
- the wire 64 which is made of metal or other conducting material, provides the necessary electrical path through the housing 30 which in this version is made from a non-conducting material such as plastic.
- FIGS. 11 - 13 illustrate a construction that is designed for use when the fence strand material 34 is a bi-polar tape. Because bi-polar tape has ground and hot wires, the wire 64 ′ is constructed differently than the wire 64 , in that the loop 68 ′ of the wire 64 ′ is provided with a plastic or other non-conducting piece 69 that divides the loop 68 ′ into separate wires 68 a , 68 b .
- One wire, for example bottom wire 68 a is designed to electrically connect to the hot wire(s) in the bi-polar tape, and runs under the cup shaped depression as shown in FIG. 11A.
- the other wire for example top wire 68 b
- the other wire is designed to electrically connect to the ground wire(s) in the bi-polar tape, and runs through the housing, as shown in dashed lines in FIG. 11, without interfering with the rotation of the roll of bi-polar tape disposed in the housing.
- the finger 60 ′ is also provided with a non-conducting piece 61 that divides the finger 60 ′ into separate wires 60 a , 60 b .

- the non-conducting pieces 61 , 69 separate the first and second electrical paths from each other.
- the lock lever 54 ′ shown in FIG. 22 having the projections 59 is used.
- the projections 59 press the bi-polar tape against the wires 60 a , 60 b .
- the projections 59 provide an improved electrical connection between the hot and ground wires in the tape exiting the housing and the wires 60 a , 60 b.
- screws 330 , 332 are threaded into bosses disposed adjacent to the wires 68 a , 68 b , with the heads of the screws contacting the wires.
- Wire leads 334 , 336 contact the screws 330 , 332 , respectively, and lead to a circuit board 338 located in the housing. In this manner, electricity can be supplied to the wire 64 ′ and to the tape.

Description
- This application is a continuation-in-part of application Ser. No. 09/672,550, filed on Sep. 28, 2000.
- The present invention relates to a fence post assembly for use in a portable fencing system and related method. The fence post assembly of the invention is particularly suited for use in forming a variety of animal enclosures, such as a portable horse corral and the like. However, the fence post assembly, fencing system and method also have utility in forming other types of enclosures or in defining other bounded areas.
- Often times it is necessary to define a temporary enclosure or bounded area in a location that does not have an existing enclosure(s) or in which one or more additional enclosures are necessary. One example of a situation in which such a need arises is when one or more horses are brought to a location not having existing enclosures or where the existing enclosures are inadequate and must be supplemented by temporary enclosures. Rodeos, horse shows, and temporary training and/or grazing sites are examples of locations at which a temporary enclosure(s) may be necessary.
- Previously, when a temporary enclosure was needed, such as for one or more horses, metallic fencing sections were generally hauled to the appropriate site and assembled to form an enclosure or horse corral. Typically, the fencing sections are heavy and difficult to assemble into a complete enclosure, as well as being hard to transport due to their weight and size. In addition, an enclosure made from metallic fencing can often be considered excessive when it is realized that an enclosure made from simpler components can adequately perform the intended function.
- Therefore a need exists for an improved fencing system for use in forming a temporary enclosure or bounded area.
- The general purpose of the present invention is to provide an improved fence post assembly, as well as a fencing system and related method utilizing the improved fence post assembly, for forming a temporary enclosure, such as a horse corral for restraining horses. The fence post assembly is provided with an extensible and retractable fence strand, such as polytape or wire, as well as a ground anchor at one end of the fence post to enable the fence post to be anchored into the ground.
- According to one aspect of the invention as defined in the claims, a fence post assembly is provided that comprises a fence post having first and second opposite ends, a ground anchor connected to the fence post adjacent the first end for anchoring the fence post, and a fence strand assembly connected to the fence post. The fence strand assembly includes an extendable and retractable fence strand, and the extendable and retractable fence strand is selectively positionable along the length of the fence post between the first and second opposite ends thereof.
- According to another aspect of the invention as defined in the claims, a portable fencing system for forming an enclosure is provided that comprises at least one fence post assembly, with the at least one fence post assembly including: a fence post having first and second opposite ends, a ground anchor connected to the fence post adjacent the first end for anchoring the post; and a fence strand assembly connected to the post. The fence strand assembly includes an extendable and retractable fence strand, and the extendable and retractable fence strand is selectively positionable along the length of the fence post between the first and second opposite ends thereof.
- In yet another aspect of the invention as defined in the claims, a method of forming an enclosure comprises providing a first fence post assembly having a fence post with first and second opposite ends, a ground anchor connected to the fence post adjacent the first end for anchoring the post and a fence strand assembly connected to the post. The fence strand assembly includes an extendable and retractable fence strand, and the extendable and retractable fence strand is selectively positionable along the length of the post between the first and second opposite ends thereof. The method further includes anchoring the fence post to the ground, extending the fence strand a sufficient amount to at least partially form an enclosure; and positioning the fence strand along the length of the fence post to achieve the desired fence strand height.
- In still another aspect of the invention, as defined in the claims, a fence strand assembly for a fence post is provided. The fence strand assembly includes a housing that includes a clamp assembly configured for releasable engagement with the fence post whereby the housing can be connected to and selectively positioned along the fence post. In addition, a fence strand material is at least partially disposed within the housing, with the fence strand material being extendable and retractable relative to the housing.
- Another aspect of the invention, as defined in the claims, provides a fencing kit that comprises a plurality of fence post assemblies. Each fence post assembly includes a fence post, a ground anchor for anchoring the post, and a fence strand assembly. The fence strand assembly includes an extendable and retractable fence strand, and means for selectively positioning the fence strand along the length of the post.

- With reference to FIG. 1, a
fence post assembly 10 in accordance with the principles of the present invention is illustrated. Thefence post assembly 10 generally includes afence post 12, afence strand assembly 14 connected to thepost 12 and adjustable along the length thereof, and aground anchor 16 at one end of thepost 12 to enable thepost 12 to be anchored into the ground. - It is to be realized that although FIG. 1 illustrates the
fence post assembly 10 as having a singlefence strand assembly 14, multiplefence strand assemblies 14 can be connected to thepost 12 to permit a multi-strand fence. In addition, multiplefence post assemblies 10 can be stacked together to provide a multi-strand fence. For instance, asecond post 12 of a secondfence post assembly 10 could be designed for securement to the end of afirst post 12, such as by using removable fasteners such as screws, whereby thesecond post 12 is stacked on thefirst post 12 to increase the height of the resulting enclosure. The secondfence post assembly 10 can include one or morefence strand assemblies 14, that cooperate with the one or more fence strand assemblies on the first post in defining the enclosure. - With continued reference to FIG. 1, as well as to FIG. 2, the
post 12 has a generally elongated, hollow, rectangular shape with afirst end 18 and asecond end 20. Thepost 12 is made from suitable material, such as metal, plastic or fiberglass. Thepost 12 can have a cross-sectional shape other than rectangular, such as triangular or round, if desired. Further, it is also contemplated that, in certain embodiments, thepost 12 could be made solid rather than hollow. - Connected adjacent to the
first end 18 of thepost 12 is theground anchor 16. Theground anchor 16 is preferably made of metal, although plastic could be used as well. As best shown in FIGS. 2 and 10A, theground anchor 16 includes asleeve 22 that fits over thepost 12 adjacent thefirst end 18. A pin, bolt, rivet or other suitable fastener (not shown) preferably extends throughholes 24 provided in thesleeve 22 and through thepost 12 in order to secure theground anchor 16 to thepost 12. Extending from the bottom of thesleeve 22 is ashaft 26 with anauger 28 disposed at the bottom end of theshaft 26. Theauger 28 permits thepost 12 to be screwed into the ground, thereby anchoring thefence post 10 into the ground. Theground anchor 16 could also be designed to fit within theend 18 of thepost 12, rather than over theend 18 of thepost 12. In one implementation, ashaft 26 having a length of about 8 to about 12 inches has been found to be effective. Other shaft lengths could be used if desired. - The details of an exemplary design of the
ground anchor 16 are illustrated in FIGS. 10A-C. Between the bottom of thesleeve 22 and theshaft 26 is aplate 21. Theplate 21 is designed to engage the ground when theanchor 16 is screwed into the ground, thereby providing stability to thepost 12. As is evident from FIG. 10A, theplate 21 is preferably a square with sides having dimension d2 so that the plate extends beyond the sides of the sleeve 22 a certain distance d1 to provide the stabilizing effect. In one implementation, it has been found that aplate 21 having a dimension d2 equaling about 3 inches, and a distance d, equaling about 0.5 inches, provides adequate stability. However, it is to be realized that other plate dimensions could be used as well. - To permit drainage of any moisture that may enter the
post 12 or thesleeve 22, at least one, and preferably two or more, weepholes 23 are provided in theplate 21 as best seen in FIG. 10B. In addition, theauger 28 is designed to facilitate insertion into the ground. If the auger is too wide, it is difficult to screw the anchor into the ground. Therefore, the dimensions of theauger 28 are selected to facilitate insertion into the ground. By way of example, theauger 28 can have the following dimensions: - d3—about 2.5 inches
- d4—about 0.5 inches
- d5—about 0.5 inches
- d6—about 0.25 inches
- R—about 1.0 inch
- about 0.666 threads per inch.
- It is to be realized that the
auger 28 can have other dimensions as well, without departing from the spirit and scope of the invention. - An alternate embodiment of a
ground anchor 210 for anchoring thepost 12 into the ground is illustrated in FIGS. 15-17. Theanchor 210 is designed to releasably self-lock with thepost 12 and permit manual disconnection of the anchor from the post. In this embodiment, the end of thepost 12 that interacts with theanchor 210 must be hollow. Theanchor 210 is preferably formed entirely from plastic, such as polycarbonate, acrylonitrile butadiene styrene (ABS) or other engineering grade plastics. - Referring to FIGS.15-16, the
anchor 210 comprises acentral body 212 that is generally hollow and has a shape that generally matches the shape of thepost 12 so that thecentral body 212 fits within the end of the post in close fitting relation therewith. The close fit between thebody 212 and the interior of thepost 12 secures the anchor and the post and prevents excessive relative movement therebetween. In the illustrated embodiment, thecentral body 212 is generally rectangular in shape so as to match the generally rectangular shape of the hollow end of thepost 12. However, thecentral body 212 could have other shapes, such as circular or triangular, corresponding to the shape of the post that is used. - As shown in FIGS. 15 and 16, a
cylindrical sleeve 214 through the center of thebody 212 defines apassage 216. Thepassage 216 permits a spike or other similar supplemental anchoring member (not shown) to extend through the center of theanchor 210 and into the ground to supplement the anchoring action of theanchor 210. A plurality of ribs 218 (only onerib 218 is visible in FIG. 16) extend between the exterior surface of thesleeve 214 and the interior surface of thebody 212 to reinforce thesleeve 214. - Surrounding the exterior of the
body 212 adjacent the base end thereof is askirt 220. Theskirt 220 includes afirst flange portion 222 that extends outwardly from thebody 212, an upwardly extendingportion 224, asecond flange portion 226 that extends outwardly from the end of theportion 224, and a downwardly extendingportion 228. Agroove 230 is defined between the exterior of thebody 212, theflange portion 222 and theportion 224, which is angled slightly away from the exterior of thebody 212. In use, thegroove 230 receives the end of thepost 12 therein, as is illustrated in FIG. 17B. - To releasably secure the post to the
anchor 210, theanchor 210 is provided with a pair ofintegral locking members members member 232 a will be described in detail. Referring to FIGS. 15 and 16, it is seen that the exterior of thebody 212 is formed with achannel 234 that receives the lockingmember 232 a. In the illustrated embodiment, thechannel 234 extends approximately the entire height of the portion of thebody 212 that projects above theflange portion 226, with thesleeve 214 defining the rear of thechannel 234 along the upper end, and with the portion of thechannel 234 below thesleeve 214 opening into the interior of thebody 210 via apassage 236. - The locking
member 232 a comprises alocking arm 238 that extends parallel to thechannel 234, with the exterior surface of thearm 238 preferably being generally even or flush with the exterior surface of thebody 212. Thearm 238 is connected adjacent one end thereof to thesleeve 214 by aconnector 240, whereby thearm 238 is cantilevered so as to permit the opposite end of thearm 238 to resiliently flex. The opposite end of thearm 238 is circular in shape and has an enlarged thickness compared to the remainder of the arm 238 (see FIG. 16) so as to form alock button 242. Thelock button 242 is sized to interact with anaperture 244 formed in thepost 12 adjacent the bottom end thereof, whereby, in use, thebutton 242 fits into theaperture 244 when thepost 12 andanchor 210 are engaged to lock the post to the anchor. Thebutton 242 is generally tapered in thickness, with the thickness increasing from its juncture with the remainder of thearm 238 to the bottom end of thebutton 242. The tapering of thebutton 242 helps the post slide over thearm 232 a as the post and anchor are being connected. - The
anchor 210 further includes a plurality of integralground engaging spikes 250 which, in use, are intended to be driven into the ground for anchoring the post. In the preferred embodiment, theanchor 210 includes fourintegral spikes 250. It is to be realized, however, that a larger or smaller number of spikes could be used. Thespikes 250 extend from the bottom of thecentral body 212 at each corner thereof. Eachspike 250 is formed from a plurality, preferably four, circumferentially even spacedribs 252. Theribs 252 are tapered such that thespikes 250 taper from adjacent thebody 212 to their distal ends. The tapering of thespikes 250 facilitates insertion of thespikes 250 into the ground, with theribs 252 providing adequate securement once the spikes are driven into the ground. Further, as described above, a spike or other member, if desired, can be inserted through thepassage 216 to supplement thespikes 250. - The locking
members post 12 to theanchor 210. With reference to FIGS. 17A and 17B, to connect the post and anchor, the end of the post is slid over thebody 212 of the anchor, and into thegroove 230 until the end of thepost 12 engages theflange portion 222. During this time, the taperedbuttons 242 are pushed inward by the post. When theapertures 244 become aligned with thebuttons 242, the resilient return force of thearms 238 force thebuttons 242 outward through theapertures 244, thereby locking the post and the anchor together. To release the post and anchor, thebuttons 242 must be pushed inward to disengage from theapertures 244, at which point thepost 12 andanchor 210 can be pulled apart. - One embodiment of the
fence strand assembly 14, best seen in FIG. 2, includes ahousing 30 that is slidably connected to thepost 12 to permit adjustment of thehousing 30 along the length of thepost 12. Thehousing 30 is preferably formed from injection molded plastic, such as polycarbonate, acrylonitrile butadiene styrene (ABS) or other engineering grade plastics. However, in certain constructions such as a non-electric fence strand version, the housing or portions thereof could be formed from a metal material if desired. - Disposed within the
housing 30 in a cup-shapeddepression 32 thereof (best seen in FIG. 4) is a roll offence strand material 34. Thefence strand material 34 is illustrated in the figures as being a tape, such as polytape. However, it is to be recognized that other fence strand members, such as wire, rope and other slender fence strand members, could be used as well. In addition, as will be described in more detail later in the description, thefence strand material 34 can be electrified to provide an electric fence system. - One end of the
fence strand material 34 extends through aslot 36 formed in the side of thehousing 30, while the opposite end of thefence strand material 34 is secured to aspindle 38. Thespindle 38, best seen in FIG. 5, includes a plurality ofslots 40 therein through which the end of thefence strand material 34 extends such that rotation of the spindle in the appropriate direction causes thefence strand material 34 to be wound onto the spindle. The bottom end of thespindle 38 forms apivot 42 which fits through a hole provided in the bottom of the cup-shaped depression 32 (see FIG. 4), with the spindle secured in place by a lockingclip 44 engaging with aslot 46 in thepivot 42. - As shown in FIGS.2-3, a
spool 48 is rotatably received at the top of thehousing 30 and closes off the cup-shapeddepression 32 so that the roll offence strand material 34 is enclosed within the housing. Thespool 48 andhousing 30 prevent ingress of water, dirt and other contaminants to the roll offence strand material 34 thereby increasing the reliability and operational life of thefence strand assembly 14. Thespool 48 includes a hole therein that receives a correspondingly shapedhead 50 on thespindle 38. As illustrated in the figures, the hole andhead 50 are rectangular in shape, although it is to be realized that other shapes, such as triangular, pentagonal or the like, could be used. - The
housing 30 is illustrated in FIG. 4 as having an open bottom. However, the housing preferably cooperates with ahousing cover 300, illustrated in FIG. 21, that closes the bottom of thehousing 30. Thehousing cover 300 has a shape that is complementary to the shape of the open bottom of thehousing 30, and is secured to the housing using screws that extend throughbosses 302 on thecover 300 and into threaded boss 304 (shown in FIG. 4) formed on thehousing 30. Thecover 300 preferably includes a plurality of weepholes 306 to allow drainage of the interior of thehousing 30. - As best seen in FIG. 3, a crank
handle 52 is disposed on, formed on, or otherwise connected to the top surface of thespool 48. The crank handle 52 is sized and shaped so as to permit manual or mechanical rotation of thespool 48. Rotation of thespool 48 causes rotation of thespindle 38, due to the fit of thehead 50 into the spool hole. Thus, thespool 48 can be rotated via the crank handle 52, thereby rotating thespindle 38, to either pay-out (i.e. extend) thefence strand material 34 or wind-up (i.e. retract) thefence strand material 34. - With reference to FIGS. 3, 4,6 a and 6 b, a locking mechanism is preferably provided in order to lock the
fence strand material 34 and prevent further retraction/extension of thefence strand material 34. The lock mechanism includes alock lever 54 that is pivotally secured on thehousing 30 adjacent theslot 36 to control ingress/egress of thefence strand material 34 through theslot 36. Thelock lever 54 includes a pair of pivot pins 56 that snap fit into suitably provided holes in thehousing 30. Aclamp bar 58 formed on thelock lever 54 forcibly clamps thefence strand material 34 against a wire finger 60 (see FIG. 4) and against thehousing 30, when thelock lever 54 is in the position shown in FIGS. 3 and 4, and prevents further ingress/egress of thefence strand material 34 through theslot 36. A scallopeddepression 62 is formed on thelock lever 54 to permit a persons finger(s) to get behind the lever to facilitate pivoting of the lever to an unlock position where thelever 54 projects from the outline of thehousing 30. - An alternate embodiment of a
lock lever 54′ is illustrated in FIG. 22. Thelock lever 54′, which is preferably used with the construction illustrated in FIG. 11, includes a series ofprojections 59 on theclamp bar 58′ enhance the clamping action of thelock lever 54′. - The
wire finger 60 discussed above forms one end of awire 64 that extends beneath the cup-shapeddepression 32 as best seen in FIG. 4. The opposite end of thewire 64 extends through aslot 66 in thehousing 30 and forms aloop 68. Theloop 68 permits connection offence strand material 34 to thehousing 30. As shown in FIG. 4, thehousing 30, such as on the bottom of the cup-shapeddepression 32, includes a plurality of wire supports 320 that holds and secure thewire 64. In addition, thehousing cover 300 in FIG. 21 includes a plurality of wire supports 322 for holding and securing thewire 64 when the cover is mounted on the bottom of thehousing 30. - With reference now to FIGS. 1, 2 and7, a
strand connector 70 is connected to the end of thefence strand material 34. Thestrand connector 70 is preferably formed from a metal, such as stainless steel, or from a suitable plastic material. Theconnector 70 includes abuckle end 72 provided with a series ofslots 74 through which the end of thefence strand material 34 is woven like a buckle so that the end of the fence strand material and theconnector 70 are securely fastened. The opposite end of theconnector 70 is formed into ahook 76 which is intended to engage theloop 68 on thewire 64 to connect the end of thefence strand material 34 to anadjacent housing 30. The construction of theconnector 70 is particularly suited for use with a tape, such as polytape, as the fence strand material. If thefence strand material 34 is slender, such as wire or rope, an alternate connector that is more suited for connection to a slender fence strand member, but which also is able to connect to the housing, could be used. - In certain electric fencing systems, the
connector 70 would preferably be formed from metal so that electrical current is transferred from the fence strand material of one housing, through theconnector 70 which connects to theloop 68 and into thewire 64 of an adjacent housing which carries the current across the adjacent housing to thefinger 60 which in turn is in electrical contact with the fence strand material of the adjacent housing as a result of the clamping action provided by thelock lever 54. In this manner, electrical continuity can be maintained. When the fence is not electrified, theconnector 70 can be either metal or plastic, and connects to the housing in the manner described or in any other suitable manner. - An optional gate handle78, illustrated in FIGS. 1 and 8, can be provided to facilitate handling of the end of the
fence strand material 34. When used, the gate handle 78 is preferably formed of extruded polyvinylchloride (PVC) or other suitable plastic, and includes achannel 80 formed therethrough. Thefence strand material 34 slides through thechannel 80 and the buckle end 72 of theconnector 70 wedges tightly into thechannel 80. Thus, when used, the gate handle 78 provides a convenient handle by which a user can grasp and hold the end of thefence strand material 34. - As mentioned, the
fence strand assembly 14 is adjustable along the length of thepost 12. To accomplish the adjustment, thehousing 30 is provided with aclamp assembly 82 that defines a shape, corresponding to the shape of thepost 12, to permit clamping engagement of thehousing 30 with thepost 12, as shown in FIGS. 14. Theclamp assembly 82 includes abolt 84, awasher 86 and aknob 88 that cooperate in a manner known in the art to tighten and loosen theclamp assembly 82. Through appropriate rotation of theknob 88, theclamp assembly 82 is loosened and thefence strand assembly 14 can be adjusted along the length of thepost 12 to the desired height. Rotation of theknob 88 in the opposite direction tightens theclamp assembly 82 and locks thefence strand assembly 14 in position. As shown in FIGS. 1 and 2, acap 90 fits into and closes off thesecond end 20 of thepost 12. The cap could also fit over, rather than within, the second end of the post. - Although a
clamp assembly 82 has been described herein as permitting adjustment of thehousing 30, other means permitting adjustment of thehousing 30 could be utilized as well. For instance, an indexing system including a plurality of indexing holes along the length of thepost 12 and an indexing pin inserted through a portion of thehousing 30 and into a selected one of the indexing holes could be used. - As described previously, the
fence post assembly 10 can be used to form an electric fence or enclosure. In an electric fence version, thefence strand material 34 must be constructed so as to permit conduction of electricity. When thefence strand material 34 is a tape, as illustrated in the figures, the type of tape used can be a bi-polar tape. Bi-polar tapes, which are generally known in the art, include a hot wire(s) and a ground wire extending along the length thereof. The fence strand tape, for either non-electric or electric uses, also preferably includes a reflective strand r extending through the center of the tape, as shown in FIG. 12, to indicate the presence of the tape at night when light reflects off of the reflective strand. - A conducting wire, rather than tape, can be used as the
fence strand material 34 if desired. A suitable type of wire is polywire. The use of wire permits a longer length offence strand material 34 to be used on thespool 48, as compared to using tape. By way of example, for the same size spool, it has been found that the length of the wire that can be used can be up to about four time greater than the length of the tape. - As discussed above, in an electric fence version, electrical continuity is required between a fence strand that connects to the
housing 30 and the fence strand that exits thehousing 30. As discussed for FIGS. 1-8, thewire 64 is one means that can be used to transfer electricity between fence strands. In this regard, thewire 64, which is made of metal or other conducting material, provides the necessary electrical path through thehousing 30 which in this version is made from a non-conducting material such as plastic. - FIGS.11-13 illustrate a construction that is designed for use when the
fence strand material 34 is a bi-polar tape. Because bi-polar tape has ground and hot wires, thewire 64′ is constructed differently than thewire 64, in that theloop 68′ of thewire 64′ is provided with a plastic or othernon-conducting piece 69 that divides theloop 68′ intoseparate wires bottom wire 68 a, is designed to electrically connect to the hot wire(s) in the bi-polar tape, and runs under the cup shaped depression as shown in FIG. 11A. The other wire, forexample top wire 68 b, is designed to electrically connect to the ground wire(s) in the bi-polar tape, and runs through the housing, as shown in dashed lines in FIG. 11, without interfering with the rotation of the roll of bi-polar tape disposed in the housing. Likewise, thefinger 60′ is also provided with anon-conducting piece 61 that divides thefinger 60′ intoseparate wires wire 60 a is connected to thewire 68 a via the portion that runs under the cup shaped depression, and thewire 60 b is connected to thewire 68 b as shown by the dashed lines in FIG. 11. Therefore, thewires wires non-conducting pieces - As further illustrated in FIG. 11, the
lock lever 54′ shown in FIG. 22 having theprojections 59 is used. When thelock lever 54′ is pivoted to the clamping position, theprojections 59 press the bi-polar tape against thewires projections 59 provide an improved electrical connection between the hot and ground wires in the tape exiting the housing and thewires - In addition, as illustrated in FIG. 11A, screws330, 332 are threaded into bosses disposed adjacent to the
wires screws circuit board 338 located in the housing. In this manner, electricity can be supplied to thewire 64′ and to the tape. Moreover, as shown in FIGS. 11 and 12, the housing preferably includes awindow 339 on the top surface thereof. A signal element, such as a light emitting diode or other illumination device, is disposed underneath thewindow 339 and is connected to thecircuit board 338 so as to illuminate when electricity is provided to thewire 64′. Thewindow 339 thus provides a readily visible indicator that the fence post assembly is powered, and that the fence strand material is electrified. - FIGS. 12, 13A and13B illustrate a
gate handle 110 that is used to connect the bi-polar tape to thehousing 30 while maintaining electrical continuity across the housing. The gate handle 110 replaces theconnector 70 and gate handle 78 arrangement described in FIGS. 1-8. Afirst clamping plate 112, shown in FIG. 13A, of the gate handle 110 cooperates with asecond clamping plate 114, shown in FIG. 13B, to clamp thebi-polar tape 34 therebetween whereby the gate handle 110 is securely attached to the end of thetape 34, as well as providing for an electrical connection between the hot and ground wires of thebi-polar tape 34 and thehook 68′ on the housing. Each clampingplate tape 34 is shown diagrammatically in FIG. 12. - With reference to FIG. 13A, the
first clamping plate 112 includes afirst end 116 adjacent which there is provided a plurality ofribs 118. Projecting from the interior surface of theplate 112 are a plurality of steppedribs 120. Theribs 120 generally increase in height as they extend from thefirst end 116 toward a second, connectingend 122 of theplate 112, with each rib including a series of relatively sharp, pointedtips 124. Theplate 112 further includes atrough 132 in which a pair ofchannels ribs 134 a, 134 b, each of which has a relatively sharp tip, extends from the interior surface of theplate 112 adjacent thechannels boss 136 projects from the interior surface of theplate 112 between thetrough 132 and the connectingend 122 and between theribs 134 a, 134 b, while an internally threadedboss 137 projects from the interior surface of the plate adjacent thefirst end 116. - With reference to FIGS. 12 and 13A, the
trough 132 forms achannel 138 that opens toward the exterior surface of theplate 112. When thetape 34 is clamped between theplates channels channel 138 so that the tape portions are accessible from outside thegate handle 110. It is the portions of the tape disposed within thechannel 138 that are to contact thewires tape 34 preferably includes a hot wire h and a ground wire g that will be located within thechannel 138 as discussed above, so that the hot wire h is able to contact thewire 68 b, while the ground wire g is able to contact thewire 68 a. - With reference to FIG. 13B, the interior surface of the
clamping plate 114 that in use faces the interior surface of theclamping plate 112 is visible. A series of projections 140 project from the interior surface of theplate 114 adjacent afirst end 142 thereof. The projections 140 are sized and shaped to fit between corresponding pairs of theribs 118 on theplate 112 when the twoplates tape 34 between theplates - In addition, a
boss 144 having a throughhole 146, and aboss 145 having a throughhole 147, project from the interior surface of theplate 114 at locations that correspond to the locations of thebosses plate 112 when the twoplates bosses plates holes bosses bosses plate 114, and thebosses gate handle 110. -
Further ribs 148 project from the interior surface of theplate 114, with theribs 148 positioned to cooperate with theribs 120 on theplate 112 in a manner to be discussed below. Eachrib 148 also includes a relatively sharp, pointedtip 152. The positioning, size and spacing of theribs 148 are such that when theplates ribs 148 are located between a corresponding pair ofribs 120. As a result, thetape 34 is firmly clamped between theplates tips tape 34 and helping to prevent thetape 34 from being pulled from thegate handle 110. - The
plate 114 further includes aflange 154 adjacent an end thereof opposite theend 142. Theflange 154 cooperates with and is positioned closely adjacent to awall 156 on theplate 112 when theplates - Returning to FIG. 13A, it is seen that the
plate 112 includes alip 158 at the connectingend 122. In use, the interior surface of thelip 158 rests on one surface of thehousing 30, as shown in FIG. 12, while the surface formed by theflange 154 andwall 156 rest on another surface. - After the
tape 34 is placed between the twoplates housing 30 in the following manner. As illustrated in FIG. 12, the connectingend 122 is inserted through theloop 68′. The gate handle 110 is then rotated so that the connectingend 122 engages with the corner of thehousing 30. In particular, the interior surface of thelip 158 rests on one corner surface, while the surface formed by theflange 154 andwall 156 rest on another corner surface, thereby achieving a secure connection of the gate handle to the housing. - Further, rotation of the gate handle110 disposes the
loop 68′ and thewires channel 138 of thetrough 132, where thewires channel 138. Thus, electrical continuity is maintained between the tape that connects to the housing, and the tape that exits the housing. Disconnection is achieved by rotating the gate handle 110 to an extent that permits theconnection end 122 to be removed from theloop 68′. - With reference to FIG. 14, in the electric fence version, electricity can be provided by the use of one or more
solar panels 150, either mounted on thefence post assembly 10 or provided as a stand alone structure. Alternatively, one ormore batteries 160 provided on or in thefence post assembly 10 can be used to provide electrical power. Preferably, the batteries are used in combination with the solar panels, with the solar panels being used to recharge the batteries. Afence controller 170 is provided for controlling operation of thefence post assembly 10. Thecontroller 170 can be mounted in a variety of locations, for example within thefence post 12 or on the exterior thereof, or it can be provided as a stand-alone unit. - FIGS.18-20 illustrate a preferred embodiment of the
fence controller 170. In this embodiment, thecontroller 170 is designed to be inserted as a single integral unit into the upper end of thepost 12 which must be made hollow to accommodate thecontroller 170. Thecontroller 170 includes achassis 172 that has abattery accommodation section 174 and acircuit board section 176, as best seen in FIG. 20. Thechassis 172, which is formed from a molded plastic such as polycarbonate, ABS or other engineering grade plastics, has a shape that is similar to the shape of the hollow end of thepost 12 to allow thechassis 172 to be inserted into the post as shown in FIGS. 18 and 19. In the preferred embodiment, thechassis 172 is generally triangular in shape which allows the chassis to be inserted into thepost 12. - The
battery section 174 of thechassis 172 is constructed to receive a plurality ofbatteries 160 for use in powering thecontroller 170 and/or in providing electricity to the fence strands, as shown in FIG. 20. In the preferred embodiment, four “D”sized batteries 160 are used. However, it is to be realized that a larger or smaller number of batteries, as well as other battery types, could be used, depending upon the power requirements. - Mounted within the
circuit board section 176 is acircuit board 178 that contains circuitry for operating thecontroller 170 and the electric version of thefence post assembly 10. The circuitry on the circuit board is designed to distribute electricity to the electric fence strand member, such as thetape 34 of FIG. 12, to electrify the fence strand member. In addition, the circuitry includes a light 180, such as a light emitting diode (LED), which flashes when the controller is on to indicate that thecontroller 170 is functioning. A pair ofindicator lights batteries 160. When thebatteries 160 have sufficient charge, the green light is illuminated indicating that the battery level is sufficient; on the other hand, when the battery charge is not sufficient, the red light is illuminated to indicate that the batteries need to be recharged or replaced. Aswitch 186, such as a toggle switch, turns thecontroller 170 on and off. - In use, when the fence strand members are to be electrified, the
switch 186 is turned to the “on” position. Once the controller is on, theLED 180 flashes thereby indicating to the user that the controller is operating. In addition, one of thelights batteries 160. - If desired, the circuitry on the
circuit board 178 could also be designed to permit remote operation of the controller. In this case, the circuitry would include equipment, such as a receiver and a transmitter, that could receive remote control commands and transmit information concerning the operation to a remote location. - Referring to FIGS.18-20, a
cap 188 disposed at the upper end of thechassis 172 replaces thecap 90 for closing the end of thepost 12. Thecap 188 is provided with a cut-out 190 on one side through which theLED 180 is visible and theswitch 186 is accessible. In addition, the indicator lights 182, 184 extend through suitable holes in the opposite side of thecap 188 so that thelights - FIG. 9 illustrates four
fence post assemblies 10A-D in accordance with the invention that are arranged to form anenclosure 100. An exemplary assembly procedure to form theenclosure 100 is as follows: the fourfence post assemblies 10A-D are located at the corners of the enclosure that is to be formed. The anchors, e.g. anchors 16 or 210, are then inserted into the ground, and theposts 12 are then attached to the anchors. Thefence strand material 34 is then unwound from the roll offence post assembly 10A by pulling on the end of the fence strand material and/or by rotating thespool 48 in the appropriate direction. The end of thefence strand material 34 is then connected to the housing on thefence post assembly 10B. A similar procedure is repeated forfence post assemblies 10B-D, with the fence strand material offence post assembly 10B connecting tofence post assembly 10C, the fence strand material offence post assembly 10C connecting to fence post assembly 10D, and the fence strand material of fence post assembly 10D connecting tofence post assembly 10A. The housings are adjusted up or down along the posts as needed to provide the desired fence strand height. Although an exemplary procedure for forming theenclosure 100 has been described, other assembly procedures could be used as well. - It should be realized that when the enclosure shown in FIG. 9 is to be electrified, the electrical continuity between the fence strand material of one fence post assembly and the fence strand material of another fence post assembly is maintained in the manner described above.
- Instead of using four
fence post assemblies 10A-D, a larger or smaller number of fence post assemblies could be used to form the enclosure. For instance, if sufficient quantity offence strand material 34 is available on the roll, the enclosure could be formed by running the material 34 from the housing of onefence post assembly 10, around man-made objects such as fence posts that do not have fence strand material rolls and housings as described herein, or around natural objects such as trees, and back to the original fence post assembly where it would connect to the housing. This type of enclosure using a fence post assembly with a single housing is particularly useful when the fence strand material that is used is wire, as the length of wire that can be used on a spool is much greater than the length of tape that can be used on the spool. - In addition, one or more of the fence post assemblies could be used in combination with existing structure(s) to form the enclosure. For instance, one or more
fence post assemblies 10 could be used in combination with a side wall of a building or vehicle structure to form the enclosure. Moreover, the end of thefence strand material 34 could be connected to the structure, rather than to an adjacent fence post assembly. - Each fence post assembly can be provided individually or as part of a kit along with one or more additional fence post assemblies. Moreover, the components of the
fence post assembly 10, including thefence strand assembly 14, thefence post 12 and theground anchor 16, can be provided as separate elements, thereby permitting replacement of one of the components in the event that a component should break, fail or otherwise need replacement. - To provide added stability to the
fence post assembly 10, aguy wire 200 can extend from a portion of thefence post assembly 10 with the opposite end of theguy wire 200 anchored to the ground. As an example, as shown in FIG. 1, theguy wire 200 can connect to theclamp assembly 82. - It is to be understood that while certain embodiments of the present invention have been illustrated and described, the invention is not limited to the specific forms or arrangements of parts described and shown. Rather, the invention is defined by the following claims.
