The invention relates to a system and method for a retractable tennis court shade device. The device is constructed such that it does not impair or provides limited impairment of the play of the game on the tennis court that is being shaded. The device can be constructed substantially along existing fencing structures to surround the entire tennis court, or it can be constructed so that it is parallel to any of the sidelines or baselines or combinations thereof. Alternatively, the device can be constructed such that it is freestanding. The device comprises a frame supported by a plurality of support columns, wherein the frame is disposed at an angle extending inward toward the tennis court while stopping short of completely covering the play area above the tennis court. A plurality of fabric shade panels are retractably attached to the frame, which fabric shade panels filter substantially all of the light and/or UV radiation from the sun. When in place, the fabric shade panels provide shade to a portion of the tennis court which varies over the day.
There are approximately 27 million tennis players in the United States, of which nearly 5 million play 21 times or more per year. Approximately 3.2 million players are youths. Most tennis players spend a lot of time outside in the sun. Accordingly, they run the risk of getting too much sun exposure which can be risky. UVA and UVB rays can cause progressive skin damage that leads to skin cancer, which is the most common type of cancer. More than a million Americans are diagnosed with it each year. The most common forms of skin cancer are basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma. Although most people develop the less harmful basal cell or squamous cell variety, melanoma can be deadly. The best way to prevent skin cancer is to stay out of the sun, but if you play a sport that takes place in the sun, you are going to be exposed. Each of these has been linked to intermittent and/or chronic sun exposure. Young and small children are especially susceptible to effects of sunlight and heat.
According to the Tennis Industry Association in its most recent TIA National Database Court Report, the total number of tennis courts in the United States is estimated at 270,000. There are significantly more outdoor courts than indoor courts.
Of the ten geographic areas with the highest density of tennis courts per population, nine of those are in southern climates. The area of West Palm Beach-Boca Raton leads in tennis court density with 2.75 total courts and 0.56 public courts per thousand residents, respectively. The only area not in a southern climate in the top ten of tennis court density is Grand Rapids, Mich., with 1.01 total courts and 0.75 public courts per thousand residents, respectively.
Tennis is played on a rectangular flat surface, usually made of grass, clay, asphalt or concrete court. The standard court is 78 feet long and 36 feet wide. Its width is 27 feet for singles matches and 36 feet for doubles matches. The service line is 21 feet from the net. Additional clearance space around the court is needed in order for players to reach overrun balls for a total of 60 feet wide and 120 feet long. A net is stretched across the full width of the court, parallel with the baselines, dividing it into two equal ends. The net is 3 feet 6 inches high at the posts, and 3 feet high in the center. Often a fencing structure surrounds a tennis court or a group of tennis courts. Typically fencing or walls around an outside court are a minimum of 8 feet high for residential courts and 10 feet for clubs or park facilities.
In 2012, the official rules and court dimensions for children aged 10 and under changed. Children 8 and under now play on a court that is 36 feet in length, which can be positioned laterally on a standard tennis court. Children 9 and 10 years old play on a court that is 60 feet in length which can be positioned within a standard court.
The area above the tennis court should be free from overhead obstruction. For indoor courts, the minimum overhead clearance free of any obstructions should be at least 20 feet above the baseline and 35 feet above the net.
While total sun exposure is dependent on the geographic location of an outdoor tennis court, the time of year, its orientation and cloud cover, outdoor tennis players are exposed to sun largely depending on the time of day. For persons such as instructors who spend a large amount of their day on the court, they are potentially exposed to a significant amount of sun over the entire day. While some persons are more susceptible to sunburn than others, all persons can experience negative effects from sun exposure if exposed for extended times. It is not always necessary during tennis instruction for the entire playing surface of the tennis court to be available, and certain lessons can be provided using only a portion of the court.
Additionally, while the temperature in the shade is the same as the temperature in a sun-exposed area, direct sunlight makes a person feel warmer because electromagnetic radiation is being embedded directly into the skin. Thus, a person standing in direct sunlight feels warmer than if standing in the shade.

FIGS. 4A1 to 4N2 depict simulations of the shading on a tennis court equipped with a retractable tennis court shade device according to one embodiment of the invention compared to the same court without a retractable tennis court shade device located in Daytona Beach, Fla. on Jun. 21, 2012 on a sunny day, showing the shading on the court over the day.
The invention relates to a system and method for a retractable tennis court shade device. The device is constructed such that it does not impair or provides limited impairment of the play of the game on the tennis court that is being shaded. The device can be constructed substantially along existing fencing structures to surround the entire tennis court, or it can be constructed so that it is parallel to any of the sidelines or baselines or combinations thereof. Alternatively, the device can be built with new construction doubling base support columns as fence posts, retrofitted to existing fence posts, or constructed such that it is freestanding. The device comprises a frame supported by a plurality of support columns, wherein the frame is disposed at an angle extending inward toward the tennis court while stopping short of covering the play area above the tennis court. A plurality of fabric shade panels are retractably attached to the frame, which fabric shade panels filter substantially all of the light and/or UV radiation from the sun. When in place, the fabric shade panels provide shade to a portion of the tennis court which varies over the day.
While the description provided herein may refer to a standard tennis court, the principles of the invention can be applied to a tennis court of any size. Further, the principles of the invention can be applied to any outdoor surface where shading is desired, including sports playing surfaces and non-sports surfaces such as parks, playgrounds and pools. The principles of the invention are not to be limited to the description provided below as can be appreciated by a person having ordinary skill in the art of designing sports playing surfaces and other outdoor surfaces.
When in use, the retractable tennis court shade device makes persons playing on the court feel cooler than if standing in the sunlight. Further, the retractable tennis court shade device provides some wind and rain protection to the tennis court.
In one embodiment, existing tennis courts can be retrofitted with the retractable tennis court shade device to provide shading from harmful sun exposure to tennis players. In this embodiment, a plurality of base support columns is installed along the exterior of the doubles or singles sidelines and/or baselines along which the retractable tennis court shade device is to stand. The base support columns can be installed substantially along existing fencing surrounding the tennis court, where such fencing exists. Additionally, frame support columns can be installed along the exterior of the doubles or singles sidelines and/or baselines along which the retractable tennis court shade device is to stand. The base of each base support and frame support column can be installed according to local building standards, and may require footings or other foundational supports. The type of foundational support that is required for the base support and frame support columns can be determined by the installer of the retractable tennis court shade device and is not intended to limit the invention in any manner. In one embodiment, three base support columns are used. In other embodiments, the number of base columns to install is determined by the user.
In one embodiment, the retractable tennis court shade device can be designed to cover none or a portion of the tennis court, according to the design specifications of the user. The amount of shading provided by the retractable tennis court shade device is equivalent to the shadow cast over the playing surface of the tennis court by the fabric shade panels which will vary according to the size and degree of inclination of the fabric shade panels, the weather conditions and the positioning of the sun with respect to the tennis court that is being shaded.
The height of each support column can be determined by the installer, and may depend on the geographic location and orientation of the tennis court that is to be shaded. The height will also vary depending on whether the support column is a base support column or a frame support column. For example, an installer may determine how much shading from sun exposure he/she wants to limit on the tennis court playing surface when designing the height of the support columns. In one embodiment, the base support columns are about 12 feet in height and the frame support columns are about 20 feet in height. In one embodiment, the base support columns are the same height as the vertical supports for fencing that may surround the tennis court. In one embodiment, the support columns have an outer diameter of about 2 feet. In one embodiment, the support columns comprise hollow structural section (HSS).
In one embodiment, e.g., during new construction, the retractable tennis shade device can utilize base support columns also as fence posts to attach fence fabric.
In one embodiment, the retractable tennis court shade device may be coupled to existing fence posts, depending on whether the existing posts can structurally support the device. In another embodiment, the retractable tennis court shade device may be free standing and adjacent to an existing fence structure.
The frame comprises a plurality of frame arms supported at their proximal ends by the base support columns. One or more of the frame arms may be supported at their distal ends by frame support columns. The proximal ends of each of the frame arms are attached at the upper end of the base support columns and extend inwardly toward the tennis court at an angle and distance determined by the installer. The determination of the angle of the attachment of the frame arms to the base support columns can depend on such factors as strength, design considerations such as the upper limit of wind tolerance and the amount of sun that is to be shaded by the fabric shade panel that will be attached to the frame. When installed in any given location, the angle formed by the attachment of the frame arms to the base support columns and the length of the frame arms determines the amount of the court that will be exposed to sunlight which will vary according to weather conditions and time of year for that particular court. By selecting the angle of attachment of the frame arms to the base support columns and the length of the frame arms, the user determines the amount of shade coverage for that particular court.
In one embodiment, the distal ends of the frame arms are each supported by a frame support column that has been installed at the exterior of each end of the tennis court, substantially in line with the doubles sidelines of the tennis court. In one embodiment, the distal ends of the frame arms are each supported by a frame support column that has been installed at the exterior of each end of the tennis court, substantially in line with the baselines of the tennis court. In one embodiment, the distal ends of one or more frame arms are supported by a frame support column that has been installed at the exterior of each end of the tennis court, substantially in line with the doubles or singles sidelines and/or baselines of the tennis court, and the distal ends of one or more frame arms may not be supported by a frame support column. For example, in one embodiment, the frame may comprise a frame arm disposed substantially in line with the centerline of the tennis court and which is supported at its proximal end to the top of a base support column but is not supported at its distal end by a frame support column. Further, in one embodiment, the frame may comprise a frame arm disposed substantially in line with the net of the tennis court and which is supported at its proximal end to the top of a base support column but is not supported at its distal end by a frame support column.
In one embodiment, the frame arms comprise hollow structural section (HSS). In one embodiment, the frame arms are attached to the base support columns and frame support columns.
In one embodiment, one or more fabric shade panels are attached to the frame which provides shading to the tennis court from the sun. In one embodiment, one fabric shade panel is disposed between any two frame arms. In one embodiment, a plurality of fabric shade panels can be attached and disposed between any two frame arms. The fabric shade panels can be manufactured using polypropylene mesh or any other material as determined by the installer. The fabric shade panels in one embodiment can be retracted when desired. For example, where the wind speed is estimated to or in fact exceeds a certain limit, the fabric shade panels can be retracted to avoid damage or injury to the fabric shade panels, to the frame arms, to the tennis court or to persons in the vicinity of the tennis court.
In one embodiment, one steel cable is strung between each frame arm substantially along the bottom edge of each fabric shade panel and one steel cable is strung between each frame arm substantially along the top edge of each fabric shade panel. In one embodiment, the steel cable is 3/8 inch in diameter. In one embodiment, the fabric shade panels comprise eyelets at the bottom edge and the top edge. In one embodiment, a ring is disposed in each eyelet through which the steel cable(s) are strung. In one embodiment, each fabric shade panel is fixedly attached along one side to a frame arm and the fabric shade panel can be drawn along the steel cables toward the adjacent frame arm in order to open or retract the fabric shade panel. In one embodiment, each fabric shade panel is fixedly attached along one side to a steel cable that extends between the base support columns and frame support columns by way of a full pin moment connection and using anchor rods with clevises, and the fabric shade panel can be drawn along the steel cables toward the adjacent frame arm in order to open or retract the fabric shade panel. In one embodiment, the user can attach a tool to one end of a fabric shade panel and draw it over the steel cables in order to retract or open the fabric shade panel. In one embodiment, one or more straps can be attached to one end of a fabric shade panel which can be used to draw the fabric shade panel over the steel cables in order to retract or open the fabric shade panel. The strap can then be secured by means of hook and loop fasteners or any other means now known or later developed.
In one embodiment, a single fabric shade panel retracts laterally along the entire length and/or width of the tennis court, depending on the installation of the retractable tennis court shade device. In one embodiment, a single fabric shade panel retracts vertically along the entire length and/or width of the tennis court. In one embodiment, two fabric shade panels retract laterally, with each fabric shade panel covering about one-half of the length of the tennis court. In one embodiment, two fabric shade panels retract vertically, with each fabric shade panel covering about one-half of the length and/or width of the tennis court. In one embodiment, four fabric shade panels retract laterally, with each fabric shade panel covering about one-fourth of the length of the tennis court. In this embodiment, the two exterior fabric shade panels retract toward the outer edges of the tennis court, and the two interior fabric shade panels retract toward the center of the tennis court and toward the frame support column disposed at the center of the tennis court. In one embodiment, four fabric shade panels retract vertically, with each fabric shade panel covering about one-fourth of the length and/or width of the tennis court.
In one embodiment, the retraction of the fabric shade panels is manual. In one embodiment, a motor is used to retract the fabric shade panels.
In one embodiment, the retractable tennis court shade device can be installed in conjunction with mesh windscreens which are commonly installed over fencing surrounding tennis courts. The mesh windscreens provide protection against wind and also provide some shade protection at certain angles of the sun with respect to the tennis court. When used in conjunction with each other, it is possible to protect a large portion of the playing surface of a tennis court with shade and thus protect from sun exposure for a majority of the day.
