This invention relates to the sport of tennis, more particularly, a sun shade umbrella stand for tennis ball carts that provides shade to tennis instructors while instructing tennis students.
Tennis is a popular sport played around the world, especially in warm climates. As in other sports, tennis requires practice for an individual to become a skilled player. This often involves coaching from tennis professionals who work as instructors. Instructors work outdoors on tennis courts teaching multiple students over extended periods of time. Unfortunately, most tennis courts provide no means for providing shade to instructors. As a result, tennis instructors are exposed to heat and sun light for extended periods of time. This exposure can lead to various problems including heat exhaustion and skin cancer. A large portion of a tennis lesson often includes a tennis professional standing in one spot near the student and feeding tennis balls to the student out of a tennis ball cart so the student can practice his or her swing. This portion of a tennis lesson provides an opportunity for the tennis instructor to obtain shade from the sun while he or she is standing next to the tennis ball cart, if such shade would be available.
Therefore a need exists for a device that will provide shade and protection from the sun to tennis instructors while they are standing near a tennis ball cart and feeding tennis balls during tennis lessons.

The primary object of the present invention is to provide a sun shade umbrella stand for tennis ball carts that allows a user to support a sun shade umbrella on a tennis court, thereby providing shade for the user.
An even further object of the present invention is to provide a sun shade umbrella stand for tennis ball carts that may be integrated into new tennis ball carts or attached to existing tennis ball carts.
Another object of the present invention is to provide a sun shade umbrella stand for tennis ball carts that allows a user to place a sun shade umbrella on either side of a tennis ball cart to accommodate an instructor whether he or she is right handed or left handed instructor.
An even further object of the present invention is to provide a sun shade umbrella stand for tennis ball carts that provides a counterweight to prevent the tennis ball cart from tipping over under the weight of a sun shade umbrella.
The present invention fulfills the above and other objects by providing a tubular stand that attaches to a tennis ball cart and provides a support for a sun shade umbrella to protect a tennis instructor from the sun and other elements. The stand is preferably a substantially U-shaped tube having a horizontal portion and two vertical portions, each vertical portion extending upward from the ends of the horizontal portion. The stand is located on a tennis ball cart so that the horizontal portion is located on the bottom surface of the tennis ball cart and the two vertical portions are located on opposite sides of the tennis ball cart. The stand may be an integral part of a tennis ball cart or a separate stand secured to an existing tennis ball cart using an attachment means, such as brackets, bolts, nuts, washers, pipe clamps, U-shaped brackets, welds, rivets, etc. The stand may also comprise two tubular vertical portions that are attached to either side of a tennis ball cart without a horizontal portion.
To use the stand, a user simply places a base of a sun shade umbrella into one of the vertical portions of the stand. The user may alternate the placement of the sun shade umbrella depending on whether the instructor is right handed or left handed and the placement of the tennis ball cart in relation to the student. An additional feature of the stand is a counter weight that may be placed in one of the vertical portions of the stand that is not being used to support the sun shade umbrella. The counterweight helps to prevent the tennis ball cart from tipping over due to the added weight of the sun shade umbrella.
