BACKGROUND OF THE INVENTIONThe present invention generally relates to fencing and, in particular, to metal fence posts. More particularly, the present invention is an improved metal fence post which is used in conjunction with wood panel and picket fences.
Traditionally, wooden fence posts have been used to construct a wooden fence. Wooden fences are very desirable because of the appearance of the fence, especially for residential homes. A conventional wood fence includes a series of vertically oriented posts which are inserted into a hole in the ground and the hole is then filled with dirt and/or cement. The posts typically have a generally square cross-section with a width and depth of about four inches. The posts are connected by two or more horizontally oriented wooden rails. The rails are typically constructed from pieces of wood measuring two inches by four inches in cross section, commonly referred to as two-by-fours. Wooden slats or fence boards are then attached to the rails to create the fence. In addition, wooden fence posts allow for the installation of prefabricated fence panels in the construction of the fence which can save the home owner or builder both money and time.
The wooden fence posts used to construct the fence, however, have a number of disadvantages. For example, wooden fence posts decompose and decay, especially the portion of the post in or near the ground. Additionally, if the posts are set in concrete, there is a danger of breakage because the posts lack resilience about their base. Finally, the wooden fence posts are typically replaced every 5-10 years because of the deterioration and rotting of the wood.
It is known to use galvanized steel pipes in place of conventional wooden fence posts. For example, as disclosed in U.S. Pat. No. 5,297,890 issued to Commins, a steel pipe is inserted into the ground and a bracket is attached to the pipe by one or more bolts. The bracket is then connected to a conventional wooden fence rail. Disadvantageously, this system requires a significant amount of time to correctly position and attach the bracket to the pipe, and the system is expensive because it requires brackets and bolts. Additionally, the aesthetics of the fence are compromised because the galvanized pipe protrudes outwardly from the wooden fence and the color of the pipe does not match the color of the fence. In addition, this type of fence post does not allow for the use of prefabricated fence panels in the construction of the fence.
It is also known to directly attach the wooden rails of a typical fence to a galvanized steel pipe. In particular, holes must be drilled or punched through the pipe and the wooden rails are then bolted to the pipe. Disadvantageously, it requires a significant amount of time to drill the holes in the pipe and to attach the fence rails to the pipe. Further, because of the great contrast between the galvanized steel pipe and the wooden fence, the aesthetics of the fence are compromised. In addition, this type of fence post does not allow for the use of prefabricated fence panels in the construction of the fence.
In order to create an aesthetically pleasing fence, known steel fence posts must be painted to match the color of the wood. For example, if a natural wood fence is desired, the steel posts are painted to match the color of the wood, but this is often very difficult because the wood may have many different colors, patterns and textures. On the other hand, if the fence and steel fence post are painted the same color, after a relatively short period of time the fence posts and fence are different colors because the steel posts and wooden fence components weather and change color at different rates. Further, in order to paint the steel fence posts, an expensive powder or primer coating is often necessary. This adds to the cost of the fence and increases the complexity of manufacturing the fence posts. In addition, this type of fence post does not allow for the use of prefabricated fence panels in the construction of the fence.
It is also known to use a galvanized post in the general shape of a hat-channel with a U-shaped center section. For example, as disclosed in U.S. Pat. No. 6,173,945 issued to Lindsey et al., a metal fence post includes a U-shaped center section with two outwardly extending flanges resulting in post with a hat-channel configuration. A series of evenly spaced penetrations extend vertically along each of the flanges to allow wooden fence rails to be attached to the flanges. Disadvantageously, the fasteners that attach the rails are inserted perpendicularly into the fence rails near the ends of those same rails resulting in a weak bond between the flange and fence rail. Thus the rails may split or crack under stress and pull away from the fence post. Additionally, the thickness of the flanges extends beyond the front surface of the rails. This makes the attachment of the fence board that is used to cover the post difficult to install. The thickness of these flanges also causes this particular board to be positioned farther away from the fence rails than the other fence boards thus compromising the aesthetics of the fence. In addition, this system also requires clips for constructing corner and end posts resulting in additional cost and labor. Additionally, constructing a gate post requires the use of two posts joined together which is more costly and labor intensive to install. Disadvantageously, hat-channels are prone to twist under stress (such as wind) along the length of their longitudinal axis thus compromising the strength of the finished fence. In addition, this type of fence post does not allow for the use of prefabricated fence panels in the construction of the fence.
Thus, known metal fence posts used with conventional wooden fences either compromise the aesthetics of the fence because the metal posts detract from the appearance of the fence or they compromise the strength of the fence itself. Further, in addition to being difficult to use and costly to install, they cannot be used with prefabricated fence panels.
BRIEF SUMMARY OF THE INVENTIONA need therefore exists for a metal post for use with a wooden fence which is simple to use and easy to install, and which eliminates the above described disadvantages and problems.
One aspect of the present invention is a metal fence post including a center section comprised of a rear wall, two sides, and two inwardly extending flanges. A series of penetrations extend vertically along each of the sides to allow wooden fence rails to be attached to the sides of the post. Preferably, the width of the sides of the post is about the same as the thickness of the wooden rails so that the fence posts are in-line with the fence rails. Advantageously, the fence posts allow the fence boards to be attached to either or both sides of the rails, and the fence posts, rails and fence boards are generally aligned. Thus, when a standard two-by four rail is attached to the post there is a smooth transition between the front surface and rear surface of both the fence rail and post respectively. This allows the fence board that is used to cover the post to be both easy to install and aesthetically pleasing.
Another aspect of the present invention is a fence post for an in-line wooden fence. The fence post includes a first flange extending along a first side of the elongated member, a second flange extending along a second side of the elongated member, the two sides interconnected by a rear wall forming a center channel with a generally C-shaped configuration. Each of the sides has a plurality of evenly spaced penetrations extending the length of the post. Preferably the two sides of the channel are about 1½ inches in width which is approximately the same as the width of a standard two-by-four. Thus, when a standard two-by-four is attached to the fence post, the front and rear surfaces of the two-by-four are generally aligned with the front and rear surfaces of the fence post.
A further aspect of the present invention is a method of constructing a fence which includes inserting a fence post into the ground. The fence post includes a front surface, a rear surface, a first side, a second side and a connecting portion interconnecting the first side and the second side. One or more fence rails are placed on either side of the fence post so that the front surfaces of the fence rails are generally aligned with the front surface of the post and the rear surfaces of the fence rails are generally aligned with the rear surface of the post. The fence rails are then attached to the sides of the fence post.
Advantageously, the fasteners that are used to attach the rails penetrate the ends of the fence rails at an angle, resulting in a large amount of surface contact between the fasteners and the fence rails. Thus, there is a strong bond between the fence rails and the fasteners and the fence rails resist cracking or splitting under stress.
In addition, another advantage of the present invention is a fence post with a C-shaped channel having a natural tendency to resist twisting along the longitudinal axis under a stress such as wind. Thus, the fence system created is able to withstand high wind loads without compromising the strength of the fence.
Advantageously, the metal fence post of the present invention allows the fence to be constructed in a variety of configurations. For example, the same fence post can be used as a line, corner, end or gate post. Thus, the fence post of the present invention is very versatile. Additionally, the fence post can be used with the fence boards in a variety of different combinations to create different appearances or the desired aesthetics. In addition, the fence post of the present invention allows for the installation of prefabricated fence panels in the construction of the fence which can save the home-owner or builder both money and time. Thus, the fence post disclosed herein has a wide variety of uses and applications.
Further aspects, features, and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments.
The appended drawings contain figures of the preferred embodiments of the present metal fence post. The above-mentioned features of the metal fence post, as well as other features, will be described in connection with the preferred embodiments; however, the illustrated embodiments are only intended to illustrate the invention and not limit the invention. The drawings contain the following figures:
The present invention involves an improved metal fence post for use with a wooden fence. The principles of the present invention, however, are not limited to metal fence posts used with wooden fences and it will be understood that, in light of the present disclosure, the fence posts disclosed herein can be successfully used in connection with other types of fences, walls and barriers.
Additionally, to assist in the description of the metal fence posts and fence systems, words such as upward, downward, vertical and horizontal are used to describe the accompanying figures. It will be appreciated, however, that the present invention can be located in a variety of desired positions-including various angles, sideways and even upside down. A detailed description of the metal fence post now follows.
The fence post 1 is desirably sized and configured to be used with fence rails. As known in the industry, fence rails are typically “two-by-fours”. However, it is known that the actual dimensions of a standard two-by-four are about 1½ inches by about 3½ inches. It will be appreciated that although the fence posts 1 described herein are in connection with standard sized two-by-fours, the fence posts may be sized and configured to be used with fence rails of different sizes. In particular, the sides 3 and 4 of the C-shaped center section 2 have a width of about 1½ inches which matches the actual thickness of a finished two-by-four. As discussed above, the fence post may have different dimensions depending, for example, upon the size and configuration of the rails and fence boards. Additionally, the dimensions of the fence post may be slightly larger or smaller, for example, depending upon the desired use of the posts.
The fence post 1 is preferably constructed from steel and more particularly from 50,000 psi steel. The thickness of the steel is preferably about ⅛ of an inch, but the steel may have any desired thickness. It will be appreciated that the post 1 can also be constructed from other types of steel, metals and other materials with suitable characteristics such as plastics or composite materials. Additionally, the fence post 1 is preferably constructed from a high-strength material and, more preferably, the fence post 1 is constructed from a material which allows a fence to be constructed to meet Uniform Building Code Section 1622 exposure B for 70 mph wind load, but the fence posts can have any desired strength characteristics. Further, the fence post 1 may be coated with materials such as paint, for example, to match the fence post with the fence or other materials to inhibit rusting of the post.
The first side 3 and the second side 4 include a series of penetrations 8, 9 respectively which extend along the length of the first side 3 and the second side 4. The penetrations 8, 9 extend through the first side 3, and the second side 4 respectively. The penetrations 8, 9 are preferably spaced about 1 inch apart, but the penetrations may have any desired spacing and arrangement. One skilled in the art will understand that instead of penetrations 8 and 9, the fence post 1 may include perforations, indentations, markings, etc., and the fence post can be constructed without penetrations.
The fence post 1 is preferably manufactured by cutting a piece of steel to the desired dimensions and then forming the steel into the desired shape of the fence post. It will be understood these steps may be performed simultaneously or independently. Alternatively, the fence post 1 could be stamped and formed from a sheet of steel. Advantageously, the penetrations 8 and 9 can be formed when the post 1 is stamped, but the penetrations may also be formed by drilling, punching, etc.
In a preferred embodiment of the present invention, as shown in
It will be appreciated that any number of rails 12 may be attached to the fence post 1 and the rails may have any desired spacing and orientation. As shown in
As best seen in
Fence boards 17 are then attached to the front surface 16 of the rails 12 by fasteners (not shown) such as nails or screws. Advantageously, because the rails 12 and fence posts 1 are generally aligned, the fence boards 17 are also generally aligned and this creates a generally straight fence wherein the posts do not extend substantially outwardly from the fence line. Significantly, if fence boards 17 are attached to one side of the fence, the fence posts 1 are generally hidden from view on that side of the fence, and if fence boards 17 are attached to both sides of the fence, the fence posts 1 are substantially hidden from view of both sides of the fence.
The details of the arrangement and connection of the fence post 1, rails 12 and fence boards 17 are best seen in
