Attachment apparatuses, systems, and methods for swing teaching and correction

Abstract

An apparatus includes a shaft having a length, from a first end of the shaft to a second end of the shaft opposite to the first end, of not less than 10 centimeters. The apparatus also includes an attachment member attached to the shaft and configured to be removably attached to a handle of a sporting bat such that a longitudinal axis of the shaft extends at an angle with respect to a longitudinal axis of the handle that is between, and inclusive of, 0 and 25 degrees.

What is claimed is: 
     
         1 . An apparatus, comprising:
 a shaft having a length, from a first end of the shaft to a second end of the shaft opposite to the first end, of not less than 10 centimeters; and   an attachment member attached to the shaft and configured to be removably attached to a handle of a sporting bat such that a longitudinal axis of the shaft extends at an angle with respect to a longitudinal axis of the handle that is between, and inclusive of, 0 and 25 degrees.   
     
     
         2 . The apparatus of  claim 1 , the shaft comprising a shaft material having a density of not greater than 1.7 grams per cubic centimeter. 
     
     
         3 . The apparatus of  claim 1 , wherein the attachment member comprises a first polymeric material. 
     
     
         4 . The apparatus of  claim 3 , wherein the shaft material comprises a second polymeric material different from the first polymeric material. 
     
     
         5 . The apparatus of  claim 1 , wherein:
 the handle comprises a knob;   the attachment member is configured to be removably attached to the knob; and   the attachment member is configured to be stretched to and/or has a width greater than a maximum width of the knob.   
     
     
         6 . The apparatus of  claim 1 , the attachment member further comprising a portion configured to conform to a shape of the knob when the attachment member is attached to the handle. 
     
     
         7 . The apparatus of  claim 1 , wherein the attachment member is made of an attachment member material having a Young's modulus of not greater than 1 and configured to allow the attachment member to be removably attached to and/or removed from the handle by stretching the attachment member material. 
     
     
         8 . The apparatus of  claim 1 , wherein the angle is between, and inclusive of, 0 and 10 degrees. 
     
     
         9 . The apparatus of  claim 1 , wherein the length is not greater than 80 centimeters. 
     
     
         10 . The apparatus of  claim 1 , the shaft further comprising:
 a first width at the first end;   a second width at the second end that is greater than the first width; and   a tapered portion between the first end and the second end.   
     
     
         11 . The apparatus of  claim 10 , wherein the shaft and attachment member are shaped to resemble the sporting bat. 
     
     
         12 . The apparatus of  claim 1 , wherein, when the attachment member is attached to the sporting bat at an end of the sporting bat, the second end of the shaft extends at least 10 centimeters beyond the end of the sporting bat along the longitudinal axis of the shaft. 
     
     
         13 . The apparatus of  claim 1 , wherein the sporting bat comprises at least one of: a baseball bat, a softball bat, a cricket bat, or any combination thereof. 
     
     
         14 . The apparatus of  claim 1 , wherein the apparatus has a weight of not greater than 0.1 kilograms. 
     
     
         15 . The apparatus of  claim 1 , the shaft further comprising a surface material that is different from a material of the handle. 
     
     
         16 . The apparatus of  claim 1 , wherein the attachment member surrounds a perimeter of the shaft at the first end. 
     
     
         17 . The apparatus of  claim 1 , wherein the shaft has a circular cross-section. 
     
     
         18 . A system, comprising:
 a shaft having a length, from a first end of the shaft to a second end of the shaft opposite to the first end, of not less than 10 centimeters; and   an attachment member configured to be removably attached to:
 the shaft; and 
 a handle of a sporting bat such that a longitudinal axis of the shaft extends at an angle with respect to a longitudinal axis of the handle that is between, and inclusive of, 0 and 25 degrees when the attachment member is attached to the shaft. 
   
     
     
         19 . A method, comprising:
 attaching a shaft to an attachment member, the shaft having a length, from a first end of the shaft to a second end of the shaft opposite to the first end, of not less than 10 centimeters; and   removably attaching the attachment member to a handle of a sporting bat such that a longitudinal axis of the shaft extends at an angle with respect to a longitudinal axis of the handle that is between, and inclusive of, 0 and 25 degrees when the attachment member is attached to the shaft and to the handle.   
     
     
         20 . The method of  claim 17 , further comprising forming the shaft from a shaft material having a density of not greater than 1.7 grams per cubic centimeter.
