Definitions
- the present invention relates to fence repair and, more particularly, repair of the horizontal rails of a split-rail fence.
- Such fencing typically comprises a plurality of vertical fence posts installed in the ground at standard intervals, and a plurality of horizontal rails connecting each post.
- the horizontal rails have roundish central portions and tapered ends.
- the rails are connected to the posts by inserting the tapered ends through bore holes in the post.
- the entire fence is subjected to prolonged exposure to moisture, weather, dry rot, insects, and external forces placed on it by animals, people, and falling objects. Since the entire wooden fence is subject to the same adverse environmental conditions, the fence typically breaks at its structurally-weakest point, namely, its tapered ends. When this occurs, the posts and other rails of the fence may still be structurally sound. In such case, only one particular rail needs repair or replacement.
- the invention provides an apparatus and method of repairing the horizontal rail of a split-rail fence that has broken at its tapered end.
- the apparatus restores the length of a broken rail to its original length in minutes and can be installed without the use of tools of any kind
- the apparatus eliminates the need to purchase an entirely new rail.
- the apparatus generally comprises an elongate, hollow sleeve having a base portion and a tapered end portion.
- the base portion and end portion have a shape that compliments the shape of the central base portion and tapered end portion of the rail, respectively.
- the base portion and end portion have interior cross-sectional dimensions that are larger than the cross-sectional dimensions of the central base portion and tapered end portion of the rail, respectively, which enable the sleeve to slide over and encase the tapered end and at least a portion of the central base portion of the rail.
- the apparatus also has means for fastening the base portion of the sleeve to the base portion of the rail.
- the tapered end of the sleeve is constructed and arranged to replace the broken tapered end portion of the rail and allow the rail to be re-installed on a split-rail fence post.
- the elongate sleeve has a uniform cross section along the central base portion and a cross-section that preferably tapers in two dimensions along the length of the sleeve.
- the elongate sleeve has open proximal and distal ends.
- the fastening means comprises at least one aperture extending through the base portion of the sleeve and a fastener extending through the aperture.
- the fastening means comprises a threaded aperture extending through the base portion of the sleeve, and a hand-tightenable, threaded fastener engaging the aperture.
- the threaded fastener may comprise a thumb screw.
- the fastening means comprises an aperture extending through the base portion of the sleeve, a threaded anchor coaxial with the aperture, and a threaded fastener engaging the anchor.
- the anchor may be fixed in or adjacent the aperture.
- the threaded fastener has an enlarged head at one end for hand tightening the fastener and a foot at the other end having a cross section larger than the cross section of the shank of the fastener.
- the fastening means may comprise a plurality of shims.
- a method for repairing a split-rail fence rail having a first end and a second broken tapered end on a fence having immovable posts using the novel repair sleeve is also provided. Initially, the broken tapered end portion is completely removed from the rail if the rail was only fractured. The sleeve is then installed by axially sliding the repair sleeve over the broken end of the rail toward the center of the rail until the end of the rail abuts the interior of the tapered end portion of the sleeve. The unbroken end of the rail is then inserted into an aperture of a first post. The second end of the rail bearing the repair sleeve is then located adjacent an aperture in a second post. The sleeve is axially slid away from the center of the rail until the tapered end engages the post aperture. The repair sleeve is then fixed to the central portion of the rail using one of the fixing means.

Furthermore, since the apparatus 9 is small and compact, one or more can be conveniently stored in a shed, barn or garage using much less space than a full replacement rail. The apparatus can be installed quickly and easily without tools and with minimal effort on the part of the user.

Description
- The present application claims priority to U.S. provisional application No. 61/516,690 entitled Rail Saver, filed Apr. 6, 2011, which is incorporated herein by reference.
- The present invention relates to fence repair and, more particularly, repair of the horizontal rails of a split-rail fence.
- Traditionally, agricultural and residential split-rail fencing has been constructed from wood. Such fencing typically comprises a plurality of vertical fence posts installed in the ground at standard intervals, and a plurality of horizontal rails connecting each post. The horizontal rails have roundish central portions and tapered ends. The rails are connected to the posts by inserting the tapered ends through bore holes in the post.
- Over time, the entire fence is subjected to prolonged exposure to moisture, weather, dry rot, insects, and external forces placed on it by animals, people, and falling objects. Since the entire wooden fence is subject to the same adverse environmental conditions, the fence typically breaks at its structurally-weakest point, namely, its tapered ends. When this occurs, the posts and other rails of the fence may still be structurally sound. In such case, only one particular rail needs repair or replacement.
- In the past when a fence rail broke or become weakened, it was necessary to replace the rail with a new rail, which can be costly as multiple rails of a long fence require repair. Furthermore, because the length of the rails is greater than the distance between posts, replacing a rail can be difficult if the fence posts are firmly set in the ground and have no leeway to sway back and forth.
- One proposed solution to rail replacement is to use an alternative wood variety, such as redwood, that has greater durability. However, such woods are typically much more expensive. Instead, some land owners attempt to splice or mend broken fence rails with varying degrees of success. However, rail repair is beyond the skill level of may agricultural land owners and most residential land owners. Therefore, it would be desirable to provide an apparatus and method for repairing the broken ends of split-rail fencing rails that is inexpensive and easy to install.
- The invention provides an apparatus and method of repairing the horizontal rail of a split-rail fence that has broken at its tapered end. The apparatus restores the length of a broken rail to its original length in minutes and can be installed without the use of tools of any kind The apparatus eliminates the need to purchase an entirely new rail.
- The apparatus generally comprises an elongate, hollow sleeve having a base portion and a tapered end portion. The base portion and end portion have a shape that compliments the shape of the central base portion and tapered end portion of the rail, respectively. The base portion and end portion have interior cross-sectional dimensions that are larger than the cross-sectional dimensions of the central base portion and tapered end portion of the rail, respectively, which enable the sleeve to slide over and encase the tapered end and at least a portion of the central base portion of the rail. In preferred embodiments, the apparatus also has means for fastening the base portion of the sleeve to the base portion of the rail.
- The tapered end of the sleeve is constructed and arranged to replace the broken tapered end portion of the rail and allow the rail to be re-installed on a split-rail fence post. The elongate sleeve has a uniform cross section along the central base portion and a cross-section that preferably tapers in two dimensions along the length of the sleeve. The elongate sleeve has open proximal and distal ends.
- In one embodiment, the fastening means comprises at least one aperture extending through the base portion of the sleeve and a fastener extending through the aperture. In another embodiment, the fastening means comprises a threaded aperture extending through the base portion of the sleeve, and a hand-tightenable, threaded fastener engaging the aperture. In this embodiment, the threaded fastener may comprise a thumb screw.
- In a further embodiment, the fastening means comprises an aperture extending through the base portion of the sleeve, a threaded anchor coaxial with the aperture, and a threaded fastener engaging the anchor. The anchor may be fixed in or adjacent the aperture. Preferably, the threaded fastener has an enlarged head at one end for hand tightening the fastener and a foot at the other end having a cross section larger than the cross section of the shank of the fastener.
- In yet an additional embodiment, the fastening means may comprise a plurality of shims.
- A method is also provided for repairing a split-rail fence rail having a first end and a second broken tapered end on a fence having immovable posts using the novel repair sleeve. Initially, the broken tapered end portion is completely removed from the rail if the rail was only fractured. The sleeve is then installed by axially sliding the repair sleeve over the broken end of the rail toward the center of the rail until the end of the rail abuts the interior of the tapered end portion of the sleeve. The unbroken end of the rail is then inserted into an aperture of a first post. The second end of the rail bearing the repair sleeve is then located adjacent an aperture in a second post. The sleeve is axially slid away from the center of the rail until the tapered end engages the post aperture. The repair sleeve is then fixed to the central portion of the rail using one of the fixing means.

Preferably, the sleeve is also made of a material that is corrosion resistant. In a preferred embodiment, the sleeve is made from UV plastic that is blow molded.
- A method of repairing a split-rail fence rail using the above-described repair sleeve is described with reference to
FIGS. 2A and 2B . Therepair sleeve 10 is useful for repairing arail 8 having a first un-broken end and a secondbroken end 8 c, and which was previously installed in afence having posts 6 that are immovable without disturbing or removing the footing in which the posts are set. - Initially, the user should remove, i.e., completely sever, the distal tip of the broken end if fractured but still intact. Then, the repair sleeve is installed by axially sliding the
sleeve 10 over thebroken end 8 c of therail 8 toward the center of the rail until the end of the rail abuts the interior of the tapered end portion of the sleeve as best seen inFIG. 2A . The first end (un-broken end) of the rail is then inserted into anaperture 7 of afirst post 6. Thebroken end 8 c of therail 8 bearing the repair sleeve is then located adjacent anaperture 7 in an opposedsecond post 6. Because the repair sleeve is in the retracted position shown inFIG. 2A , a clearance is created between the distal end of the repair sleeve and thepost 6, which would typically not be possible if a new, full-length rail was installed. Once the repair sleeve is aligned with theaperture 7, the repair sleeve is slid axially away from the center of the rail until thetapered end 14 engages thepost aperture 7 as seen inFIG. 2B . The sleeve may then be affixed to the rail to prevent further axial movement of the sleeve by tightening any one of the fixing means described above. - The above-described method is especially useful when the
posts 6 are firmly set in the ground and provide no leeway to move laterally along the fence line. If theposts 6 are loosely set in the ground, therepair sleeve 10 may be installed in the extended position shown inFIG. 2B before the rail is re-installed on the posts. Using this technique, the fence post would be forced laterally to create an alignment gap, such as shown inFIG. 2A , between the repair sleeve and postaperture 7 before inserting the rail in the aperture. - The
apparatus 9 and method of the present invention provide a less expensive alternative to replacing an entire fence rail. Furthermore, since theapparatus 9 is small and compact, one or more can be conveniently stored in a shed, barn or garage using much less space than a full replacement rail. The apparatus can be installed quickly and easily without tools and with minimal effort on the part of the user. - While the principles of the invention have been described above in connection with specific embodiments, it is to be clearly understood that this description is made only by way of example and not as a limitation on the scope of the invention. For example, it is conceived within the scope of the present invention that the repair sleeve could be applied to the ends of a fence rail that is not broken to reinforce the fence rail at those locations. This application of the invention has particular use along areas of the fence that experience frequent, excess loads, wear, or deterioration due to external forces. The apparatus may also be used to repair fence rails made of concrete, plastic or metal.
