BACKGROUND

1. Field
This application relates to an athletic training device that limits movement of the elbow joint of the arm.
2. Prior Art
Several training aids that limit elbow joint angle during athletic training are represented by U.S. Pat. No. 5,544,877 to Brownell, U.S. Pat. No. 5,865,695 to Mahala, Qualben, and Meurer, U.S. Pat. No. 5,651,743 to Stephen, Pryor, and Williams, and U.S. Pat. No. 5,344,152 to Brannen. All of these training aids are designed to limit the elbow joint angle during athletic movement of either basketball or golf.
U.S. Pat. No. 5,544,877 to Brownell and U.S. Pat. No. 5,865,695 to Mahala, Qualben, and Meurer are designed to assist a basketball player in developing the proper form when shooting a basketball. Specifically, it addresses limiting the elbow joint angle. Both of these devices use rigid materials and multiple straps to affix the device to the arm. Due to the need to position multiple straps, these devices are difficult to properly position on the arm. The hard nature of the materials used could cause injury to others if the device were worn during scrimmages or drills. The weight of these devices creates undo stress on the shooting arm. The rigidity of these devices can be uncomfortable for the user. These devices are cumbersome and uncomfortable to wear as they extend the entire length of the arm.
U.S. Pat. No. 5,651,743 is designed to assist a basketball player in developing the proper form when shooting a basketball. Specifically, it addresses limiting the elbow joint angle. This device employs a piece of “L” shaped plastic affixed to the bicep with a Velcro strap. The device is made of a rigid material that could cause injury to others if the device were worn during scrimmages or drills. The plastic element of this device is prone to fracture under stress. The hard plastic can also be uncomfortable for the user.
U.S. Pat. No. 5,344,152 is designed to assist the golfer in developing the proper elbow angle when swinging a golf club. This device employs a triangular shaped hollow piece of plastic affixed to the bicep with a Velcro strap. The plastic element of the device is very rigid and can pinch during use. Due to the shape and rigidity of the plastic triangle, users with larger arms can be restricted to angle less than 90 degrees. The weight of this device can create a less than lifelike feel.
The device noted in this application has several advantages over the prior art. The device is very light and extremely comfortable. The sleeve is comprised of stretchable and adaptable fabric. This allows each user to get a personalized, comfortable fit. The foam block is very light and soft yet provides just enough resistance for training purposes. The entire device is machine washable for improve hygiene over the prior art. The device can be worn while training or scrimmaging with other athletes without the risk of injuring someone with the device. The sleeve provided with this device can be used without the training block for muscle compression and moisture wicking during training and competitive events. These and other advantages will become apparent from consideration of the following description and drawings.

SUMMARY

The embodiment the elbow joint training device is comprised of an arm sleeve made of stretchable, moisture wicking fabric with a strategically adhered loop Velcro patch and a foam training block with hook Velcro adhered. The training block is designed in the shape of a right angle triangle. The athlete simply slides the sleeve on the arm to be trained and affixes the training block via the Velcro adhesion. This gives the athlete a lightweight, comfortable, and safe device that still provides enough resistance for proper elbow joint training.
The object of this device is to give athletes a versatile aid for training the elbow joint angle without limiting the arm motion of the other aspects of the sporting movement. Prior to the start of training or practice session, the athlete simply slides the customized stretchable sleeve on their arm and affixes the desired angle training block to the sleeve. By wearing the device, the elbow joint of the athlete will have a physical obstruction that prevents the athlete from using an elbow joint angle that is detrimental to performance. Consistent use of the device will allow the athlete to develop muscle memory of the proper elbow joint angle thus leading to enhanced performance.
