发明名称 Disc Launching Mechanism and Method
摘要 The “DISC LAUNCHING MECHANISM AND METHOD” was originally invented due to common flaws seen in most youth baseball/softball swings which is an inadequate grip and rolling the top hand over too soon which causes the bat to jump off the intended swing path and ultimately leads to a miss or inaccurate strike. With the present invention, that would equate to poor disc flight. The axe-shaped handle naturally promotes a proper baseball/softball grip. Incorporating a disc, resting on a flat shaft and anchored with spring holding mechanisms and using a tacky surface under the back of the disc to create drag, allows the disc to be held in place until the proper speed and swing-angle are reached. In testing the present invention, it was observed that it could be used for any disc launching entertainment such as disc golf or disc home run derby.

主权项 1. A disc launching mechanism comprising: a handle and shaft which make up the foundation of the present invention. a launcher at the top of the main flat shaft shaped in the likeness of a human thumb in front and which is shaped like a ramp in the back portion to allow the disc to ride up the back as the disc rotates out of the spring holders as a result of swing force. There are spring holders at each end of the main shaft to hold the disc flat and snug at rest. The spring holder at the top of the main shaft rests on another lighter weight flat surface which protrudes from the main shaft. a friction area at the bottom of the main shaft to create drag and delay the launch of the disc until almost 90 degrees is reached.
