1. Field of the Invention
The present invention generally relates to fences, boundaries, boarders and other types of barriers, and, in particular, to fences constructed from metal and/or plastic.
2. Description of Related Art
Conventional fences are made from many different types of materials. For example, many conventional fences are constructed from wood. Conventional wooden fences typically have an attractive initial appearance, but maintaining that initial appearance may require significant effort because of exposure of the wood to the elements. For example, conventional wooden fences must be periodically repainted or restained. In addition, conventional wooden fences may rot or deteriorate over time. Accordingly, the rotted or damaged portion of the fence may have to be repaired or replaced. Thus, conventional wooden fences frequently require periodic maintenance, which is time consuming and may be relatively expensive. Furthermore, conventional wooden fences may be difficult to install and skilled artisans may be required, which may increase costs and expenses.
Known fences are also constructed from vinyl. Conventional vinyl fences may also have an initially attractive appearance, but these fences may deteriorate and/or discolor over time. For example, many conventional vinyl fences can become brittle from exposure to certain weather conditions, such as prolonged exposure to sunlight. Moisture, such as water from a sprinkling system, may also discolor many conventional vinyl fences. Further, many conventional vinyl fences are not very strong and may be damaged from various types of impacts. In addition, many conventional vinyl fences are not securely connected together or fixed in a stationary position and may be damaged, for example, by a sudden gust of wind. Disadvantageously, it may be difficult and expensive to repair and/or replace portions of a conventional vinyl fence.
It is also known to construct all or a portion of a fence from concrete. Conventional fences constructed from concrete are typically very expensive install, repair, replace and remove. In addition, many conventional concrete fences require skilled artisans to install, repair, replace and/or remove a concrete fence. Further, many individuals are unable to install or remove a conventional concrete fence by themselves so they are required to hire others for assistance.
Conventional fences are often installed around a person's lawn or garden. Disadvantageously, many conventional fences disrupt or hinder a person from taking care of their lawn or garden. For example, many conventional fences increase the difficulty of mowing the lawn. In particular, many people have grass growing next to or proximate the fence. Most conventional lawn mowers, however, are unable to cut the grass close to the fence. Accordingly, that portion of the grass may not be cut by the lawn mover and a grass trimmer may have to be used to cut that portion of the grass, which undesirably increases the amount of time to mow the lawn. In addition, many conventional grass trimmers may damage the fence if the trimmer inadvertently contacts the fence. To prevent grass from growing proximate the fence, it is known to place a concrete curb or mow strip along the fence, but this can be rather costly and time consuming. The concrete curb or mow strip may also be rather unattractive and it may make the fence more difficult to install and/or remove.
A need therefore exists for a fence that eliminates or diminishes the above-described disadvantages and problems.
One aspect is a fence or barrier that may be constructed from relatively lightweight materials. For example, all or a portion of the fence may be constructed from plastic. Advantageously, the lightweight materials may allow the fence to be easily moved and transported. The lightweight materials may also allow the fence to be easier to install and remove.
Another aspect is a fence that may be constructed from blow-molded plastic. Advantageously, the fence may contain hollow interior portions that are formed during the blow-molding process, which may allow a light-weight fence to be constructed. In addition, if the fence is constructed from blow-molded plastic, then the blow-molded plastic portions may be relatively easily formed into many different desired shapes, sizes, configurations and designs depending, for example, upon the intended use and/or configuration of the fence. Significantly, all or a portion of the fence may be constructed from blow-molded plastic.
Still another aspect is a fence that may be generally maintenance free. In particular, the fence preferably does not require any significant maintenance over time or any periodic maintenance. For example, the fence preferably does not require any painting, staining or the like. Advantageously, if the fence is constructed from blow-molded plastic, then the fence may require very little, if any, maintenance. Thus, for instance, if the fence is constructed from the blow-molded plastic, then the fence may be constructed from plastic with a specific color and the fence never has to be painted.
Yet another aspect is a fence that may be attractive and/or include an eye-catching design. If desired, these various features and designs can be integrally formed as part of the fence. For example, if the fence is constructed from blow-molded plastic panels, various features and designs can be integrally formed in the panels as part of a unitary, one-piece structure. In particular, one or both sides of the blow-molded plastic panels may include a design. Advantageously, the design on the sides of the panels may be the same or different, which may increase the versatility and potential uses of the fence. In addition, because blow-molded plastic panels may be formed into many different shapes, sizes, configurations and designs, that may allow many different shapes, sizes, configurations and designs of fences to be constructed.
A further aspect is a fence that may have enhanced visual appeal. In particular, a fence constructed from blow-molded plastic may have a stronger and/or sturdier appearance than a conventional fence. Thus, the fence may desirably have a more rugged or durable appearance.
A still further aspect is a fence that may include one or more components that are constructed from blow-molded plastic. Advantageously, the blow-molded plastic components may be generally weather resistant and temperature insensitive, which may allow the fence to be used in a wide variety of locations and environments. In addition, the blow-molded plastic fence may be durable and long-lasting because it generally does not corrode, rust or otherwise deteriorate over time. Further, the blow-molded plastic fence may be generally waterproof and/or windproof, which may also allow the fence to be used in a wide range of locations and environments.
Still yet another aspect is a fence that may be relatively strong and impact resistant. For example, the fence may be constructed from blow-molded plastic components and this may allow the fence to withstand relatively large forces or impacts without being damaged. For example, the fence may be able to withstand repeated impacts with balls, toys, bicycles and the like without being damaged. Advantageously, this may help prevent the fence from being damaged by children, pets and the like.
A fence including components constructed from blow-molded plastic may be relatively strong because the blow-molded plastic components may include two opposing walls or surfaces that are separated by a given distance. The opposing walls may help create a strong, high-strength and rigid fence. In addition, a relatively lightweight fence may be constructed because the interior portion of the blow-molded plastic components may include a hollow interior portion. While the opposing walls of the fence are preferably separated by a generally constant distance, the walls can be separated by any suitable distance.
Still another aspect is a fence that may be constructed from blow-molded plastic and the blow-molded plastic components may include one or more depressions or “tack-offs.” The depressions, which may extend from one surface towards another surface, are desirably sized and configured to increase the strength and/or rigidity of the fence. Preferably, the depressions extend from one surface and contact or engage an opposing surface, but the depressions do not have to contact or engage another surface. Advantageously, the depressions may form part of a design or pattern formed in the fence, and the design or pattern may minimize and/or hide the depressions from view. In addition, the depressions may be formed in one or both sides of the fence. If the depressions are formed in both sides of the fence, the depressions may be generally aligned. At least a portion of these opposing depressions may contact or engage each other, but the opposing depressions do not have to touch or engage.
Significantly, a fence constructed from blow-molded plastic components may be relatively quickly and easily constructed. For example, the blow-molding process may allow opposing walls, depressions and other desired features to be quickly and easily formed. In addition, the blow-molded plastic components may allow the fence to be quickly and easily assembled. Further, the blow-molded plastic components may allow portions of the fence to be easily repaired, removed and/or replaced.
Advantageously, if the fence is constructed using blow-molded plastic components, then the blow-molded components may allow a strong and sturdy fence to be constructed. For example, the blow-molded plastic components may include opposing walls and depressions, which may allow the components to be constructed with relatively thin outer walls. Significantly, this may reduce the amount of plastic required to construct the components, which may reduce manufacturing costs and the amount of required resources. The thin outer walls may also allow the components to be cooled more quickly during the manufacturing process, which may allow the fence to be manufactured more quickly and efficiently.
Additionally, because the fence may be constructed using blow-molded plastic components with thin outer walls, this may allow a fence with reduced weight to be constructed. Significantly, the lightweight fence may be more easily transported, which may decrease shipping costs. Additionally, the consumer may appreciate the reduced weight because they can much more easily move and/or assemble the fence. Further, the lightweight components may allow the fence easier to install, repair and remove.
A further aspect is a fence that may be constructed from blow-molded plastic and one or more features may be integrally formed in the fence as part of a unitary, one-piece structure. For example, one or more connectors, fasteners, receiving portions and the like may be integrally formed in the blow-molded plastic components. Advantageously, this may reduce the number of steps required in the manufacturing process, which may reduce the overall cost of the fence. This may also make the fence easier to assemble and install.
Another aspect is a fence that may include portions that are constructed from plastic, such as blow-molded plastic, and other portions that are constructed from other materials such as metal. This may allow a more decorative or attractive fence to be created. For example, the fence may include ornamental metal components that are attached to upper and/or lower portions of a blow-molded plastic panel. The fence could also include metal components that are structural portions of the fence and/or metal components that allow the fence to be more quickly and easily assembled and installed. Advantageously, the metal portions may be disposed inside and/or outside the blow-molded plastic portions. Thus, the metal portions could be disposed within the bow-molded plastic portions so that the metal portions are not visible or outside the blow-molded plastic portions so that the metal portions are visible.
A still further aspect is a fence that may include one or more features or aspects, such as mow strips, that can readily be connected to the fence or are formed as part of the fence. For example, the fence may be sized and configured to allow features such as mow strips to be easily attached to or positioned near the fence. On the other hand, features such as mow strips may be integrally formed as a unitary part of the fence. Advantageously, this may allow the fence to be easily assembled and/or constructed.
Yet another aspect is a fence that may include a plurality of panels which may be interconnected. For example, the fence may include panels that are about eight to ten inches in width and four to six feet in height. The panels may be interconnected to form the fence. Advantageously, the fence may be constructed with a wide variety of different types and sizes of panels. For example, the panels may be larger or smaller. In addition, the panels may be different designs, colors, textures and the like. If desired, the panels may be mixed and matched for texture and variety. In addition, the panels may allow the fence to more easily follow the contour of the ground. Of course, the panels could have various suitable designs and configurations depending, for example, upon the intended use of the fence.
Still another aspect is a fence that may include one or more connectors or connecting portions that are sized and configured to interconnect one or more panels. The connectors or connecting portions, for example, may allow the panels to be slidably or rotatably connected. The connectors or connecting portions may also connect the panels by a friction, snap or interference fit. Advantageously, the connectors or connecting portions may allow the panels to be quickly and easily connected. The connectors or connecting portions may be connected using any suitable type of fasteners such as screws, bolts and the like.
Still yet another aspect is a fence that may include one or more supports that are sized and configured to support the fence. For example, the supports may be positioned between adjacent panels and the supports may allow or facilitate connection of the panels. Advantageously, the supports may form a part of a support frame and the frame and/or supports may allow the panels to be interconnected. Further, the frame and/or supports may allow covers, caps, finials and the like to be connected to the fence.
These and other aspects, features and advantages of the present invention will become more fully apparent from the following detailed description of preferred embodiments of the invention and the appended claims.
The appended drawings contain figures of preferred embodiments to further clarify the above and other aspects, advantages and features of the present invention. It will be appreciated that these drawings depict only preferred embodiments of the invention and are not intended to limits its scope. The invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
The present invention is generally directed towards a fence. The principles of the present invention, however, are not limited to fences. It will be understood that, in light of the present disclosure, the structures disclosed herein can be successfully used in connection with other types of structures, barriers, boundaries, boarders, fixtures, equipment and the like.
Additionally, to assist in the description of the fence, words such as top, bottom, front, rear, right and left may be used to describe the accompanying figures. It will be appreciated, however, that the fence can be located in a variety of desired positions and angles. A detailed description of the fence now follows.
As shown in the accompanying figures and described in greater detail below, a fence may include a plurality of sections that are interconnected to form the fence. For example, the fence may include a plurality of panels and support structures that are interconnected to construct the desired type and configuration of fence. Advantageously, the panels and/or support structures may have a variety of shapes, configurations and designs, and the panels and/or support structures may be connected in various suitable arrangements, which may allow various types and sizes of fences to be constructed. This may allow the fence to be used in a wide variety of locations and environments.
Various portions of the fence, such as the panels and support structures, may be constructed from lightweight materials such as plastic. For example, the panels may be constructed from high density polyethylene and formed using a blow-molding process. Advantageously, the blow-molded panels may include a hollow interior portion, which may allow the weight of the panels to be decreased. The panels, however, could be constructed from any materials with appropriate characteristics and using any suitable process.
The blow-molded plastic panels may be relatively lightweight, which may be advantageous to manufacturers, retailers and consumers. For example, a manufacturer or a retailer may have reduced shipping costs associated with the lightweight, blow-molded plastic panels. The lightweight, blow-molded plastic panels may also be more conveniently moved or stored. In addition, the blow-molded plastic panels may allow the fence to be moved and constructed with fewer persons, which may make it a more desirable option for consumers.
The blow-molded plastic panels may also be resistant to weather conditions, such as heat, cold, rain, snow, and the like. Accordingly, the weather-resistant, blow-molded plastic panels may be used to construct a fence that lasts longer than conventional fences constructed of weather-sensitive materials. Although blow-molded plastic panels may have advantages, it will be appreciated that the panels could be constructed from other suitable material (such as wood, metals, plastics, composites, and the like) having desired characteristics.
As shown in
The post portions 12, the cross portions 14 and/or the panels 16 may be formed as an integral part of a unitary, one-piece fence section 10. Advantageously, the post portions 12, the cross portions 14 and/or the panels 16 may be constructed from plastic and formed as a unitary, one-piece structure during a blow-molding process. It will be appreciated that the post portions 12, the cross portions 14, and/or the panels 16 could also be formed as separate pieces and these components could be constructed from other suitable materials and processes depending, for example, upon the intended use of the fence. It will also be appreciated that the post portions 12, the cross portions 14 and the panels 16 may have various suitable sizes, configurations, designs and arrangements.
The fence sections 10 may include one or more support members and the support members may be sized and configured to increase the strength and/or structural integrity of the fence sections. For example, as seen in
As shown in
The support structure 18 is preferably constructed from relatively strong or high-strength materials to allow, for example, a strong and sturdy fence to be constructed. In particular, the support members 20, 22 are preferably constructed of metal, such as steel, or other relatively strong materials. The support members 20, 22 preferably have a relatively long length to support a large portion of the fence. For instance, the support members 20, 22 may consist of an elongated rail, a post, tubular member or the like. The support members 20, 22 are preferably generally straight, but the support members may also be angled, curved or the like. One of ordinary skill in the art will appreciate that the support structure 18 and the support members 20, 22 may have a variety of suitable designs, shapes and configurations depending upon the intended use of the fence. Further, the support structure 18 and the support members 20, 22 may be constructed from other suitable materials having suitable characteristics.
As shown in
Advantageously, the fence 24 may include one or more features that are formed as part of the fence or that can be connected to the fence. For example, as shown in
In greater detail, as shown in
The mower strip 26 may be constructed of a lightweight material, such as plastic. Preferably, the mower strip 26 is constructed of high density polyethylene and the mower strip is constructed using a blow-molding process. In addition, the mower strip 26 is preferably formed as a unitary, one-piece structure, which may help prevent the undesirable growth of grass and/or weeds about the various sections of the fence 10. While the mover strip 26 is preferably constructed from blow-molded plastic, it will be appreciated that the mower strip may be constructed from other suitable materials and processes.
The blow-molded plastic mower strip 26 may be relatively lightweight, which may provide advantages to manufacturers, retailers, and consumers. For example, a manufacturer or a retailer may have reduced shipping costs associated with the lightweight, blow-molded plastic mower strip. The blow-molded plastic mower strip 26 may also be more conveniently moved, stored and installed. Additionally, the blow-molded plastic mower strip 26 may be weather and impact resistant. Although the blow-molded plastic mower strip 26 has advantages, it will be appreciated that the mower strip 26 could be constructed from other suitable materials and processes.
