1. Field of the Invention
The invention relates generally to enclosures for tennis courts and more particularly to a convertible, retractable and customizable enclosure system for tennis courts that includes windscreen panels, highly tensioned cables and fasteners.
2. Description of Related Art
Traditionally tennis courts employ the use of chain link fences as a means of ball containment. It is known in the art to use windscreens in conjunction with a chain link fence to block the wind, provide a background for the ball, enhance privacy and add security.
For example U.S. Pat. Appl. No. 2010/0116446 (to Willett) discloses a windscreen assembly for attachment to a fence. In Willett, a windscreen system includes mounting panels that are affixed to a fence, with a main windscreen sheet attachable to the mounting panels.
Another problem that arises with the use of windscreen panels used in conjunction with barriers, such as chain link fences, is that high wind oftentimes causes the windscreen to become detached from the chain link fence and become damaged. The constant detachment of the screens from the chain link fence also creates a maintenance problem by having to replace the fastening mechanisms regularly. Additionally, if the windscreens are not removed when a wind storm approaches, the chain link fence itself is at risk of completely blowing down as most are not designed to withstand the windloads with the windscreen attached.
In an attempt to limit the damage, prior art designs include one or more holes or flaps in the windscreen to allow the wind to blow through the covers and reduce the billowing or flapping effects. However, the prior art has achieved limited success in addressing the issue of windscreen or fence blowing down in heavy wind.
U.S. Pat. Appl. No. 2007/0138456 (to Clark) discloses a device and method relating to a cover for a barrier, such as for a fence or the like which allows the cover to be secured to a barrier so that the cover remains substantially against the barrier. The barrier cover has a front and rear portion. The rear portion has an upper pocket, a lower pocket and at least one web and apertures. The upper and lower pockets may have flexible support members extending therethrough. The web may be located between the upper pocket and the lower pocket. The web may define a plurality of pockets oriented substantially transverse to the upper pocket and the lower pocket.
Henning patent application U.S. Pat. Appl. No. 2007/0125994 discloses a wind shield system for mounting on a fence. The Henning reference teaches an apparatus and method for shielding an area from wind comprising at least one windscreen that yields to wind to facilitate, reduce or eliminate stresses or forces on a fence to which a windscreen is attached.
The continued use of chain link fences presents several difficulties and inconveniences. Chain link fences tend to rust and are difficult to assemble and disassemble. In addition, chain link fences are particularly susceptible to high winds and other environmental hazards. Further, chain link fences have often been described as aesthetically unappealing.
It is therefore desirable to have an eco-friendly, durable and customizable enclosure system for tennis courts that is simple to assemble or disassemble and that also provides the added benefit of being retractable and also dispenses with the use of a chain link fence.
The present invention provides a customizable enclosure system for tennis courts that also eliminates the use of chain link fences.
The present invention utilizes a plurality of windscreen panels that are connected to highly tensioned cables via the use of fasteners, such as snap clips or zip ties. The windscreen panels are composed of a resilient fabric comprising a thermoplastic polymer, most commonly a vinyl-coated polyester. The windscreen panels are retractable and may be easily slid along the tensioned cables to allow for retraction of the windscreen panels in order to open the enclosure. It may be advantageous to retract the windscreen panels and open the enclosure for various reasons, including the need to minimize damage to the windscreens in the event of inclement weather, including high winds and hurricanes or to enjoy an otherwise unblocked view.
The present invention requires the installation of two or more vertical support members in a concrete foundation at prescribed distances. Once the vertical support members are installed, high working load, corrosion resistant stainless steel cables are connected to the vertical support members. Preferably, the cables are a rigid low-flex, 1×19, 3/16 inch, wire rope uncoated stainless steel with a rounder profile shape. Preferably, the cables have a relatively high breaking load.
The cables are connected to the vertical support members via toggle with captive pin or bolt and nut to a compression clamp or eye bolt. A closed-body turnbuckle assembly is utilized to tension each length of cable. Preferably, a closed-body turnbuckle is used, because the closed turnbuckle assembly provides for a smoother transition from cable to fittings.
At least two cables extend horizontally from the top and bottom of a first vertical support member to the corresponding top and bottom of a second vertical support member positioned at a prescribed distance from the first vertical support member. In a preferred embodiment, at least three cables extend horizontally from the top, middle and bottom regions of a first vertical support member to a second vertical support member.
The windscreen panels include seams positioned at the top, middle and bottom of each windscreen panel. The top and bottom windscreen panel seams include spaced apertures, slots or grommets for receiving a fastener or snap clip to secure the windscreen panel to the top and bottom of the tensioned cables. In an alternative embodiment, a mounting panel or tab is affixed to the top and bottom portion of the windscreen panel seams to act as an accent.
The windscreen panels are further provided with end pockets for receiving support poles to allow tensioning along the full height of the windscreen panel. Adjoining support pole members are affixed together using fasteners, for example zip ties and the like. Alternatively, the pole members may be secured directly to the vertical support members.
The enclosure system of the present invention provides a foundation for customization capabilities not easily achieved by chain link systems.
An advantage of the present invention is that the system requires less structural support than a traditional chain link fence. Another advantage is that the present invention requires fewer and lighter weight components than a traditional chain link fence.
Still another advantage is that the present invention is not susceptible to corrosion in the same manner as a chain link fence.
Yet another advantage is that the system of the present invention is customizable and retractable. Another advantage is that the system of the present invention is environmentally friendly. Another advantage is that the system of the present invention is that eliminates the need for a chain link fence.
The above-mentioned and other features and advantages of this invention, and the manner of attaining them, will become more apparent and the invention itself will be better understood by reference to the following description of embodiments of the invention taken in conjunction with the accompanying drawings, wherein:
The detailed embodiments of the present invention are disclosed herein. It should be understood, however, that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limited, but merely as the basis for the claims and as a basis for teaching one skilled in the art how to make and/or use the invention.
The subject invention, dispenses with the use of a chain link fence and provides a novel improvement over other tennis enclosures using closed body turnbuckle assemblies with toggles and captive pins and multiple rigid steel cables to connect two vertical support members at corresponding top, mid and bottom points, and thereafter connecting a windscreen panel to the cables and vertical support members along a horizontal plane at said corresponding top, mid and bottom points.
The present invention contemplates the use of a windscreen panel 12 secured to a plurality of highly tensioned cables 14, 14′ and 14″ to form a windscreen panel assembly 10. A plurality of said windscreen panel assemblies 10 may thereafter be joined to form a customizable enclosure system that is ideal for tennis courts and dispenses with the use of chain link fences.
Referring now to
In a preferred embodiment each windscreen panel 12 has a height in a range of eight to ten feet and a length in a range of twenty to thirty feet. The third reinforced seam may be positioned at a general midpoint of four to six feet. In an alternative embodiment, a windscreen panel 12 may have a height of six feet. Where the windscreen panel 12 has a height of six feet or less, the windscreen panel 12 will include only first and second reinforced seams 16, 18. A third reinforced seam 20 is found to be necessary only in windscreen panels 12 with a height in excess of six feet. In a preferred embodiment, the third reinforced seam 20 is formed by first joining then sealing together seamed edges of two windscreen panels 12 as shown in
Referring to
Each windscreen panel 12 includes a pocket 28 positioned on either end of the windscreen panel 12 along a vertical plane relative to the first, second and third reinforced panel seams 16, 18 and 20. The pockets 28 and 28′ extend beyond the main windscreen panel 12 along the height, h, of the windscreen panel 12 as shown in
Each pocket 28, 28′ is fabricated from the same material as the windscreen panel 12, namely a resilient fabric such as vinyl-coated polyester.

Referring to
In one preferred embodiment, the present invention utilizes three cables 14, 14′ and 14″ to secure a windscreen panel 12 to vertical support members 36, 36′. An important aspect of the present invention is that the cables 14, 14′ and 14″ are fabricated of a low-flex, as opposed to flexible steel. The cables 14, 14′ and 14″ comprise a rigid steel, capable of securing a high working load and a high breaking load. In a preferred embodiment, cables 14, 14′ and 14″ comprise 1×19 uncoated wire rope, 3/16 inch rigid stainless steel having a round profile shape.
The vertical support members 36, 36′ may be formed of steel, aluminum, wood or other suitable material as will be appreciated by one reasonably skilled in the art. The vertical support members 36, 36′ are permanently affixed in bedrock or a concrete foundation 38 at prescribed distances as shown in
Once the vertical support members 36 are permanently affixed to the concrete 38, cables 14, 14′ and 14″ are secured to vertical support members 36 as shown in
A closed-body turnbuckle assembly 42 with toggle 44 may be used to tension and secure a cable 14″ to a supporting member 36 as shown in
Referring now to
It should be appreciated that the cables 14, 14′, 14″ may be tensioned via tensioning means, such as the closed-body turnbuckle assembly 42 to one or more vertical support members 36 from either end of the length of each of the cables 14, 14′, 14″. However, the cables 14, 14′, 14″ need not be tensioned from both ends of the length of each cable 14, 14′, 14″, and may be tensioned from only one end using the closed-body turnbuckle assembly 42.
In a preferred embodiment, cable 14 is fixedly attached to corresponding vertical support members 36, 36′ at a top point 46, located generally 4 to 6 inches from the apex of the first and second vertical support members 36, 36′ as shown in
Referring to
Fasteners or plastic snap clips 24 pass through the grommets 22 positioned along the first reinforced windscreen panel seam 16 to affix the windscreen panel 12 to cable 14. Similarly, fasteners or plastic snap clips 24 pass through the grommets 22 positioned along the second reinforced windscreen panel seam 18 to affix the windscreen panel 12 to the cable 14″ connecting corresponding vertical support members 36, 36′ at a corresponding bottom points 50, 50′.
Cable 14′ connecting corresponding vertical support members 36, 36′ at mid point 48, 48′ is connected to the third reinforced panel seam 20 positioned along the center of the windscreen panel 12 using fasteners such as, for example snap clips 24.
The pockets 28 of the windscreen panel assembly 10 include two apertures 52 positioned generally at a point ¼ from the apex of the pole 30 and two apertures 52 positioned ¾ from the apex of the pole. The apertures 52 are sized to receive a zip tie 54 for securing a rigid pole support member 30 of a first windscreen panel assembly 10 to an adjacent rigid pole support members 30″ of a second windscreen panel assembly 10′ when two or more windscreen panels are in a neighboring configuration as shown in
In an alternative embodiment, a fastener, such as for example a zip tie may be used to secure two adjacent rigid pole members 30, 30″ with a common vertical support member 36.
The windscreen panel 12, once affixed to the cables 14, 14′ and 14″ may be easily retracted as shown in
The windscreen panel 12 affixed to the snap clips 24 is pushed along cables 14, 14′ and 14″ where it slides into a retracted position and is gathered accordion style. Once retracted, the windscreen panel 12 may be tied together at a top 46 and bottom 50 position as shown in
In an alternative embodiment, if the windscreen panel 12 does not exceed six feet in height, there is no need for a third reinforced seam 20 and the windscreen panel 12 will be secured to vertical support members 36 and 36′ with cables 14 and 14″ along a first and second reinforce seam 16, 18.
A rectangular configuration as disclosed is ideal for a tennis court enclosure as illustrated in
