SLAT REINFORCEMENT FOR VINYL FENCES
A fence having a reinforcement member for vinyl fence slats is provided. An elongate reinforcement member is disposed in hollow cavities formed in the fence slats to strengthen the slats against bending. The reinforcement member may be located in different fence slats in a section of fence according to the type of fence and the environment in which the fence is located.
The present application claims the benefit of U.S. Provisional Application Ser. No. 61/496,786, filed Jun. 14, 2011, which is expressly incorporated herein by reference in its entirety.
THE FIELD OF THE INVENTIONThe present invention relates to vinyl fences. More specifically, the present invention relates to a reinforcement structure which fits inside of vinyl fence slats and which stabilizes the vinyl fence slats against bowing.
BACKGROUNDVinyl fences are becoming increasingly more popular fences. Vinyl fencing offers many advantages over traditional fencing materials such as wood. For example, vinyl fencing does not deteriorate as wood fencing does, and does not require refinishing as wood fencing does. Vinyl fencing, however, does have some disadvantages. Vinyl, as a material, is flexible and also experiences moderate expansion due to temperature changes.
The flexibility of vinyl often allows more movement than is desired when force is applied to the pickets or slats of a vinyl fence. For example, children playing soccer and kicking a ball against the fence slats will often cause the slats to bend back and forth. Similarly, children walking next to a fence will often push on or otherwise play with the fence, causing the slats to bend or bow. Moderate bending of the fence slats is undesirable and it is viewed negatively by the fence owner and may also cause scuffing of wear of the fence. Higher degrees of bending may even kink or permanently bend the fence slat, damaging the fence and requiring replacement of the damaged fence slats.
Another problem experienced by vinyl fence slats or pickets is the bending of the slats due to the sun causing one side of the slat to be hotter than the other side of the slat. The warmer side of the fence slat facing the sun will expand due to the heat, causing the fence slats to bow. This effect is more pronounced in the darker fencing material colors which are becoming more popular. In some cases, fence slats may bow as much as 2 inches or more due to the sun heating one side of the fence.
Regardless of the cause, excessive bending of the fence slats reduces the perceived quality of the fence and can cause damage to the fence. As such, there is a need for improved fencing to strengthen the fence slats and pickets. There is a need for an economical method to strengthen the slats and pickets and prevent bowing and bending of the slats due to environmental conditions as well as physical contact with the fence.
SUMMARY OF THE INVENTIONIt is an object of the present invention to provide an improved vinyl fence slat and system for strengthening vinyl fence slats and pickets.
According to one aspect of the invention, a vinyl fence slat is provided which includes a metal reinforcement. According to another aspect of the invention, a metal reinforcement is provided which is removable from the vinyl fence slat, and which may be retrofitted to existing fences. The metal reinforcement may be added to vinyl fencing as is needed to control bending in the fence slats. According to another aspect of the present invention, a vinyl fence is provided which includes a metal reinforcement in some of the fence slats but not in other fence slats within the same fence panel.
These and other aspects of the present invention are realized in a reinforced vinyl fence slat as shown and described in the following figures and related description.
Various embodiments of the present invention are shown and described in reference to the numbered drawings wherein:
It will be appreciated that the drawings are illustrative and not limiting of the scope of the invention which is defined by the appended claims. The embodiments shown accomplish various aspects and objects of the invention. It is appreciated that it is not possible to clearly show each element and aspect of the invention in a single Figure, and as such, multiple figures are presented to separately illustrate the various details of the invention in greater clarity. Similarly, not every embodiment need accomplish all advantages of the present invention.
DETAILED DESCRIPTIONThe invention and accompanying drawings will now be discussed in reference to the numerals provided therein so as to enable one skilled in the art to practice the present invention. The drawings and descriptions are exemplary of various aspects of the invention and are not intended to narrow the scope of the appended claims. The term ‘slat’ is frequently used herein to represent both vinyl fence slats and pickets.
Turning now to
As discussed above, existing vinyl fences suffer from excessive bending in many applications. Contact from children, balls, etc. causes the fence to bend excessively. Sunlight causes uneven temperatures on different sides of the slats and causes them to bend. The bending is undesirable and unsightly, and can also cause scuffing or damage to the fence. If bent too far, the slats may kink or become permanently deformed. In winter weather, excessive bending may cause the vinyl to crack. In some cases, the slat may become sufficiently bent to come out of the fence rails. The bending is problematic because of the damage that it may do to the fence. The bending is also problematic in that it lowers the perceived quality of the fence. Many homeowners do not want a fence which bends as discussed.
To remedy the bending problems associated with the vinyl slats 26, the present invention uses metal reinforcement members 46 which are inserted into some of the cavities of the fence slats 26. The reinforcement members are shown in
It will be appreciated that the dimensions of the reinforcement member 46 may vary according to the size of the slat 26. Where the slats 26 are thicker or thinner, the reinforcement member 46 may also be thicker or thinner. The particular size of the reinforcement member 46 is typically chosen to allow a person to easily insert the reinforcement member into a cavity 30.
There is thus disclosed an improved reinforced vinyl fence slat. It will be appreciated that numerous changes may be made to the present invention without departing from the scope of the claims.
