Abstract
This invention relates generally to training a user how to correctly throw a ball, and more specifically, a training, physical, or occupational therapy aid that can be used to strengthen and rehabilitate a user's muscles and joints.
Description
BACKGROUND OF THE INVENTION

Many people have the desire for correcting the way they throw a ball. In the sport of baseball, it is common for pitchers to have poor form when pitching the ball. One of the most common improper ways of pitching a ball is termed a “side arm.” Repetitive side arm motions can result in debilitating deterioration of the elbow joint and ligament, otherwise known as a Tommy John, affectionately named after the first baseball player to undergo surgery for this type of injury. This injury ultimately requires invasive surgery to repair the elbow joint and ligament. Surgery required for correcting this injury is known as ulnar collateral ligament reconstruction. In the event that the surgery is not successful, the player's career could end.


Also problematic is the injury that young ball players can sustain from an improper throwing technique. If the growth plate, the medial epicondylar epiphysis, is still open, repeatedly throwing in a side arm fashion will exert excessive force on the growth plate and cause failure in this location, rather than at the ulnar collateral ligament. This injury is commonly known as “Little League Elbow,” and although it does not require reconstruction of the ulnar collateral ligament, it is still a very devastating injury for a young ball player to sustain. However, injuries caused by improper throwing techniques can be prevented by the use of correct throwing techniques.


Currently, there are devices available, such as an elbow brace, which assists with correctly positioning the arm during ball throwing. There are also devices available for strengthening the arm or shoulder. In addition, there are devices available that assist the user with throwing a ball or other object across a distance. However, these devices do not assist with training a user to improve or correct their throw, or to strengthen a user's arm or shoulder after an injury. Consequently, there is a need for a ball throwing training device that is easy and intuitive to use.


The present invention overcomes several of the deficiencies, disadvantages and undesired parameters associated with known ball throwing training apparatuses.


SUMMARY OF THE INVENTION

The invention is a unique ball throwing training device. The ball throwing training device has a longitudinal body portion containing a proximal end and a distal end. The device also has a first ball shaped object coupled to the distal end of the longitudinal body portion. In one embodiment of the ball throwing training device, the longitudinal body portion is made from an inflexible material. The inflexible material can be fiberglass, metal, plastic or wood. Additionally, the longitudinal body portion can be made up of two or more longitudinal body portions of variable size. The two or more longitudinal body portions of variable size can be joined together by any means. Optionally, the longitudinal body portion can have a moveable portion proximate to the distal end of the longitudinal body portion. The moveable portion can be a pivot joint, a flexible portion, or a spring mechanism. The moveable portion can also have a locking mechanism to prevent the moveable portion from moving or bending. The first ball-shaped object can be coupled to the distal end of the longitudinal body portion via mechanical means. The mechanical means can be a screw, nail, clip, snap, ball joint, or an adhesive. The first ball-shaped object can be any size. Optionally, the first ball-shaped object can be a ball, such as, for example, a baseball, a softball, a tennis ball, or a football. Optionally, the ball throwing training device can have a second ball-shaped object coupled to the proximal end of the longitudinal body portion. The second ball-shaped object can be any size. The second ball-shaped object can be a ball, and it could be a baseball, a softball, a tennis ball, or a football. The second ball-shaped object can be coupled to the proximal end of the longitudinal body portion via mechanical means. The mechanical means can be a screw, nail, clip, snap, ball joint, or adhesive. Optionally, a strap can be coupled to the device and the user.


The invention is also a method of using the ball throwing training device. The method of using the ball throwing training device includes the steps of first grasping the first ball-shaped object in the user's hand, placing the longitudinal body portion underneath the user's arm and against the user's side, then placing the proximal end of the longitudinal body portion against the lower back of the user such that the user's hand holding the first ball-shaped object is above shoulder height and rotating the user's arm such that the hand holding the first ball-shaped object rotates from above the user's shoulder height to below the user's shoulder. The rotation of the user's arm forward lifts the proximal end of the longitudinal body portion.


The invention can also be used as an arm and shoulder strengthening device. The strengthening device has a longitudinal body portion and a first ball-shaped object. The longitudinal body portion has a proximal end and a distal end and the first ball-shaped object is coupled to the distal end of the longitudinal body portion. Optionally, the longitudinal body portion can be made up of two or more longitudinal body portions of variable size. The arm strengthening device can also have a second ball-shaped object coupled to the proximal end of the longitudinal body portion. Optionally, a strap can be coupled to the device and the user.

The segmented longitudinal body portions can be coupled together in any order via any mechanical means, such as, for example, a screw, nail, clip, snap, ball joint or adhesive.


The longitudinal body portion 114, the first, second, third and fourth segmented longitudinal body portions 104, 106, 108, and 304, and the head portion 110 can be made from any inflexible material such as, for example, fiberglass, metal, plastic, wood, aluminum, steel, carbon fiber, steel alloy, copper tubing, bamboo, paper, glue, rubber, glass, tin, leather or brass.


As with the ball throwing training device 100 previously described, the ball throwing training device with pivot joint 300 can have a first ball-shaped object 102 coupled to the distal end of the longitudinal body portion 114, and optionally a second ball-shaped object 112 can be coupled to the proximal end of the longitudinal body portion 114.



FIG. 4 shows an exploded view of the movable pivot joint 302. The movable pivot joint 302 comprises a top piece 402 and a bottom piece 406. FIG. 4A shows a view of the top piece 402 with pivot pin 404 of the movable pivot joint 302 from the top and FIG. 4B shows a view of the top piece 402 from the side. FIG. 4C is a view of the bottom piece 406 with pivot pin 404 from the top and FIG. 4D is a view of the bottom piece 406 from the side. Pivot pin 404 holds the top piece 402 and bottom piece 406 together. The top piece 402 has a first hole 408 for the pivot pin 404 to pass through. The bottom piece 406 has a second hole 410 for the pivot pin 404 to pass through. The top piece 402 has an elongated portion 412, which is designed to fit between the two extensions 414 of the bottom piece 406. When the elongated portion 412 from the top piece 402 is sandwiched between the two extensions 414 of the bottom piece 406, the first hole 408 and the second hole 410 line up, and the pivot pin 404 passes through and creates the movable pivot joint 302. Optionally, the movable pivot joint 302 can have a means for locking the pivot joint, making the pivot joint unmovable, as described further below.



FIG. 5 shows the motion that the movable pivot joint 302 provides for the ball throwing training device with pivot joint 300. FIG. 5A shows the movable pivot joint 302 before it is pivoted by the user. FIG. 5B shows the movable pivot joint 302 in the pivoted position. The longitudinal body portion 114 remains stationary while the head portion 110, while the first ball-shaped object 102 attached to the distal end of the head portion 110 pivots to the desired position.


Referring now to FIG. 6, there is shown a diagram of a locking mechanism 602 that is designed to lock the pivot joint 302 in a straight position. The locking mechanism 602 can be in the form of a sleeve that slides up and around the pivot joint 302, preventing the pivot joint 302 from moving. Optionally, the locking mechanism 602 can be spring loaded to provide easy use.


Optionally, the locking mechanism 602 can comprise a first opening 606 and a second opening 608. There can also be a button 604, which can be located in the bottom piece 406 of the pivot joint 302. The button 604 can be spring loaded for easy use. When the locking mechanism 602 is in the “unlocked” position, the locking mechanism 602 is below the pivot joint 302, and the button 604 is extending up through the second opening 608 in the locking mechanism 602. To activate the locking mechanism 602 and move it into the “locked” position, the user must depress the button 604 out of the second opening 608, slide the locking mechanism 602 up and over the pivot joint, and allow the button 604 to extend up through the first opening 606 in the locking mechanism 602, which prevents the locking mechanism 602 from sliding off the pivot joint 302. To disengage the locking mechanism 602, the user depresses the button 604 out of the first opening 606, slides the locking mechanism 602 down and off the pivot joint 302, and allows the button 604 to extend up through the second opening 608.


Ball Throwing Training Device with Flexible Portion


It is also contemplated that the moveable portion made out of flexible material. Referring now to FIG. 7, in one embodiment of the ball throwing training device 100, the longitudinal body portion 114 is coupled to a flexible portion 704. The flexible portion 704 has first connector 702 on the proximal end of the flexible portion 704. The first connector 702 can be coupled to the distal end of the longitudinal body portion 114. The flexible portion 704 also has a second connector 706 attached to the distal end of the flexible portion 704. The second connector 706 is coupled to the proximal end of head portion 110. The distal end of head portion 110 has a mechanical means 202 to couple to the first ball-shaped object 102.


The flexible portion 704 is designed to be freely manipulated in any direction by the user, to achieve the desired positioning with very minimal effort. This allows for easy accommodation of users still recovering from injuries. Due to the injuries they may not be able to achieve the desired throwing position.


Ball Throwing Training Device with Straps or Harness


It is contemplated that the ball throwing training device 100 can contain a means for attaching the ball throwing training device 100 to the user. In one embodiment with a harness, the proximal end of the longitudinal body portion 104 can be coupled to a waist belt or harness to secure the ball throwing training device 100 to the user in the correct position. The use of a harness 900 is shown in FIG. 9. The harness 900 is attached to the user's waist by a first belt 910. The harness can optionally have straps 916 that extend from the first belt 910 horizontally across the user's back and is fastened around the users chest and upper back by means of a second belt 918. The second ball-shaped object 112 is attached to the first belt 910 at a location 912 in the center of the user's lower back by a first flexible means 914, such as an elastic strap or retractable cord. The harness can also be attached to the second belt 918 by a second flexible means 920, such as an elastic strap or retractable cord.


In another embodiment of the ball throwing training device 100, the proximal end of the first longitudinal body portion 114 can be strapped to the user's arm in order to secure the ball throwing training device 100 in the correct position (not shown). The straps can be located around the user's wrist and bicep.


A harness 900 or straps can also be used with the ball throwing training device with pivot joint 300 or flexible portion 704.


Use of the Ball Throwing Training Device


FIG. 8 depicts the method of using the ball throwing training device 100. The placement of the ball throwing training device 100 and movement allowed by the ball throwing training device 100 corrects the user's form, and aligns the user's elbow properly in order to avoid improper throwing form the damaging side-arm motion. The user grasps the first ball-shaped object 102 in either hand, and positions either the proximal end of the longitudinal body portion 114, or the second ball-shaped object 112, against their lower back, so that the longitudinal body portion 114 runs along the back of the user, against the user's side, under the user's arm and along the user's forearm. The user then raises their hand and arm to the desired starting position, which is ideally above shoulder height. The user then moves the ball into a second ending position that is lower than the starting position. The user moves the ball by rotating their arm forward such that the ending position is below the user's shoulder. This rotation forward can also involve some rotation of the wrist forward as well. This movement will cause the first ball-shaped object to rotate on the head portion 110, and causes the proximal end of the longitudinal body portion to move away from the user's lower back. However, the longitudinal body portion will remain against the user's side.


In the case of a ball throwing training device with pivot joint 300, the device starts in the same starting position as described above for the ball throwing training device 100. The user then moves the ball into an ending position that is lower than the starting position by rotating their arm forward. In use, the first ball shaped object is stationary relative to the head portion 110, and only the movable pivot joint 302 moves during use. FIG. 5A shows the movable pivot joint 302 in the starting position. FIG. 5B shows the movable pivot joint 302 in the ending position.


Similarly, in the ball throwing training device with flexible portion 704, the user holds the device in the starting position. The user then moves the ball into an ending position that is lower than the starting position. In use, the first ball shaped object is stationary relative to the head portion 110, and only the movable flexible portion 704 moves during use, and then automatically returns to the starting position.


When used with a harness 900, the user attaches the harness 900 by means of the first belt 910 and optional second belt 918. The second ball-shaped object 112 is attached to the first belt 910 at a location 912 in the center of the user's lower back by a first flexible means 914, such as an elastic strap or retractable cord. The harness can also be attached to the second belt 918 by a second flexible means 920, such as an elastic strap or retractable cord. The user grasps the first ball-shaped object 102 in the first starting position and moves it to the ending position. The second ball-shaped object 112 moves from a first position to a second position when the first ball-shaped object 102 is moved from the first starting position to the ending position. The harness in combination with the first flexible means 914 can provide resistance for the user's muscles.


Use of the Device as an Arm and Shoulder Strengthening Device

It is also contemplated that any of the ball throwing devices described above can be used as an arm and shoulder strengthening device. The movement described above can strengthen areas of the arm and shoulder. In use, the device engages the user's arm, shoulder, neck and trunk muscles, such as, for example, forearm flex muscles, forearm extensor muscles, biceps, triceps, deltoids, chest muscles, side muscles, and trapezius muscles. The device can be used in physical or occupational therapy as an aid to strengthen a user's arm, shoulder, and trunk muscles.
