Patent ID: 8491423

Claim:
A training aid for a batter comprising: a. a barrel having a top end opposite a tapered bottom end with a threaded hole centrally disposed in the tapered bottom end; b. a handle having a first end and a second end; c. a knob secured to the first end; and d. a connection assembly for connecting the barrel to the handle, wherein the connection assembly comprises: (i) a housing secured to the second end opposite the knob, wherein the housing has a top surface through which is disposed an inner chamber disposed adjacent to a central fastening chamber, wherein the inner chamber has a plurality of inner engagement holes, wherein each inner engagement hole receives a pointed fastener with a pointed end, wherein the top surface has a plurality of top engagement holes, and wherein each top engagement hole receives a flat faced fastener; (ii) a first half split flange with first half engagement holes and a second half split flange with second half engagement holes, wherein the first half split flange and the second half split flange form a tapered surface, and wherein the first half split flange and the second half split flange are positionable over the top surface for aligning the first half engagement holes and the second half engagement holes with the top engagement holes; (iii) a pivoting connector comprising: 1. a ball with a pin hole centrally disposed in the ball and an outer groove disposed around a perimeter of the ball for accepting the pointed end of each pointed fastener; 2. a conical skirt, wherein a top portion of the conical skirt is connected to the ball opposite the pin hole; and 3. a threaded extension having an outer diameter less than an outer diameter of the conical skirt centrally extending from the conical skirt opposite the top portion, wherein the threaded extension engages the threaded hole, and wherein the first half split flange and the second half split flange allow the ball and the conical skirt to rotate freely there between; and (iv) a pin for slidingly engaging the pin hole and the central fastening chamber simultaneously, wherein the connection assembly is configured to maintain an angle of one hundred eighty degrees between the barrel and the handle when a batter uses proper swing mechanics, and wherein the connection assembly is configured to allow an angle different than one hundred eighty degrees between the barrel and the handle when the batter does not use proper swing mechanics.
