This application claims the benefit of U.S. Provisional Application No. 60/646,138, filed on Jan. 21, 2005, the entire disclosure of which is incorporated herein by reference.
FIELD OF THE INVENTIONThe invention relates to fencing systems and more particularly, to modular fencing systems for confining horses and other animals to a desired area.
BACKGROUNDModular fencing systems are well known in the art and typically include a plurality of posts which are mounted in the ground and one or more rails which extend between the posts. A modular fencing system may be used to provide a confined area for horses or other animals, and may include electrically energized wires that enable the horses or other animals to quickly learn that the fence sets the boundary. Furthermore, a modular fencing system may be oriented in many different configurations and are generally mounted permanently in either gravel or in concrete.
The posts and rails of modular fencing systems may be made from an extruded plastic material such as high density polyethylene (HDPE). Modular fencing systems made from HDPE can be had in a variety of colors with posts and rails extruded in different cross-sectional shapes, and are typically of low maintenance. Moreover, the extruded HDPE posts and rails have high impact and flex strength which permit the fencing system to absorb impact without shattering, cracking, or splintering, even at temperatures well below freezing. Finally, the HDPE posts and rails are generally non-toxic and therefore often safe for animals which may attempt to eat the posts or rails of the fencing system.
While current modular fencing systems are well suited for their intended uses, they are nevertheless susceptible to certain improvements. For example, the long-term durability of the HDPE posts and rails may be limited to less than ten years in harsher environments due to cracking, rail sagging, and color fading over time. In addition, the hardware used for assembling the rails to the posts and connecting the electrically energizable wires (used in electric safety fence versions of such modular fencing systems) makes fence assembly more time consuming than it should be.
Accordingly, there is a need for a modular fencing system that has increased long-term durability and which is easier and quicker to assemble.
SUMMARYOne embodiment is a fencing system comprising a fence section and first and second retainers. The fence section of the system comprises first and second fence posts, a first rail extending between the first and second fence posts, the first rail having first and second opposing end portions, the first end portion extending through an opening in the first fence post and the second end portion extending through an opening in the second fence post. The first retainer of the system is connected to the first end portion of the first rail and the second retainer of the system is connected to the second end portion of the first rail, thereby connecting the first rail to the first and second fence posts.
Another embodiment is a fencing system comprising a fence section and a sliding gate slidably attached to the fence section.
Still another embodiment is a fencing system comprising a first fence section comprising first and second fence posts, a first fence rail extending between the first and second fence posts, and at least one electrical conductor at least partially embedded in the fence rail. The at least one electrical conductor is operative for providing a safe but uncomfortable electric shock when contacted.
BRIEF DESCRIPTION OF THE DRAWINGS
A modular fencing system for horse and animal containment, and other applications, is disclosed herein. A first aspect of the modular fencing system are the fence sections of the fencing system. An exemplary embodiment of one of the fence sections is shown in
As shown in the sectional view of
The fence posts 110 may be installed by simply embedding them in the ground. This is possible due to the hollow construction of the posts 110. The hollow construction of the posts 110 along with the nonporous and self lubricating properties of the post material, as will be described further on, prevents them from being lifted out from the ground by frost heaves. If desired, the fence posts 110 may also be installed in the ground using other suitable and appropriate post securing methods, such as embedding the posts in cement.
Another aspect of the modular fencing system is a sliding gate. An exemplary embodiment of the sliding gate is shown in

Referring to the cross-sectional view of
The fence posts 110, 110.1, 110.2, the fence rails 120, 120.1, 120.2, the gate posts 210.1, 210.2 and the gate rails 220 (hereinafter posts and rails) may be formed to any suitable and appropriate length. In some exemplary embodiments, the posts and the rails may each have a circular transverse cross-sectional shape to make it difficult for the horse or animal to solidly land a kick on the fence system. In such embodiment, the posts may each have an outer diameter of about 5.30 inches and the rails may each have an outer diameter of about 3.0 inches, which provide good visibility for the horse or other animal. In other exemplary embodiments, the posts and the rails may be constructed in other suitable and appropriate diameters, and may have other transverse cross-sectional shapes including, without limitation, oval, rectangular, square, hexagonal, irregular, and the like.
Various embodiments of the posts and the rails can be concurrently used in the fencing system. In addition, the fencing system may have a greater (e.g. 4 or more rails) or lesser number of rails (e.g. 2 rails) than shown in
In some exemplary embodiments, as shown in
The HDPE inner “wall” layer 300 provides the posts and the rails with high impact strength, even at low temperatures to prevent cracking, shattering, and splintering. The PC/PBT protective outer coating layer 310 also has excellent low temperature (subzero ° F.) impact strength. In addition, the PC/PBT protective outer coating layer 310 retains its color, thereby resisting fading, provides improved weather-ability for longer life, and provides improved heat resistance, which prevents the rails from sagging. Furthermore, the non-porous and self-lubricating properties of PC/PBT outer layer 310 and the hollow post construction allow the posts to resist heaving (as mentioned earlier). Still further, the self-lubricating PC/PBT outer layer 310 prevents ice from sticking to the posts and the rails.
One of ordinary skill in the art will appreciate that the posts and rails may also be made from other suitable and appropriate materials and manufactured using other or correspondingly suitable and appropriate forming techniques.
Referring again to
A further aspect of the modular fencing system is an electrical shocking system. In some exemplary embodiments, as generally shown in
The power supply is constructed to provide a voltage and current which energizes the conductors 331 and 332 of the conductor pair 330 in manner that will provide the horse or other animal with a safe but uncomfortable electric shock when the horse or other animal contacts the both conductors 331, 332. After a few encounters with the embedded electrical shocking system, the horse or other animal quickly learns the fencing system sets the boundary. The embedded electrical shocking system also trains the horse or other animal not to chew, crib or lean on the fencing system.
In alternative embodiments, as shown in
The conductors 331, 332, 340 of the electrical shocking system may comprise any thin, bare, electrically conductive single or multi-strand wire, cable and line. In some exemplary embodiments, the conductors 331, 332, 340 may each comprise a stainless steel wire having a thickness Twire of about 0.020 inches.
In embodiments where the rails are co-extruded from HDPE and PC/PBT, the conductors 331, 332, 340 may be at least partially embedded into the outer PC/PBT resin layer 310 of the rails, as shown in
Although not shown, in some embodiments, the sliding gate 200 shown in
Yet another aspect of the modular fencing system is a rail-to-post retaining system for facilitating easy installation of the fencing system of the invention and preventing the ends of the rails from being withdrawn through the openings of the posts after the fencing system has been assembled. In some exemplary embodiments, the rail-to-post retaining system may comprise a retaining rod 400 as collectively shown in
As shown in
In other exemplary embodiments, the rail-to-post retaining system may comprise a retaining pin 500, as collectively shown in
In operation, the pin 500 may be inserted through the opposing apertures 121, 122 formed in the end of the rails 120 to retain the end of the rail 120 within a respective post 110, as shown in
In still other exemplary embodiments, the rail-to-post retaining system may comprise a pin strap collectively shown in
The pin strap 700 may be used to retain an end of a rail 120 within a respective post 110 as shown in
The pin 500 and pin strap 700 may be made of any suitable and appropriate material, such as plastic, and may be formed using a suitable and appropriate forming technique. In some embodiments, the pin 500 and pin strap 700 may be formed using plastic injection molding. When using plastic injection molding, the grooves 550, 750 formed in the outer surfaces 511, 711 of the pin 500 and pin elements 706, 707 substantially prevent the formation of shrinkage voids along the central axis of the generally cylindrical, solid body of the pin 500 and pin elements 706, 707 during the plastic injection molding process.
The retaining pin 500 and/or pin strap 700 may be used to retain any of the rails to any of the posts. As shown in
A further aspect of the modular fencing system is a twist wire connector for physically connecting the free ends of the at least partially embedded conductors (wires) of adjacent fence sections. In some exemplary embodiments, as collectively shown in
The twist wire connector 600 may be made of any suitable and appropriate material, such as plastic, and may be formed using a suitable and appropriate forming technique, such as plastic injection molding.
