A method of fitting a golf club head by determining an initial swing plane using a measuring device, determining a desired swing plane, and applying an asymmetrically shaped visual indicator to a golf club head based upon the determined initial swing plane and the desired swing is also provided. | 11-18-2010 |
| 20120190473 | VARIABLE STIFFNESS SPORTS EQUIPMENT - Many sports rely upon the use by the sportsperson of one or more pieces of sports equipment such as bats, rackets, clubs, boards etc. Typically these items of sports equipment employ a shaft having predetermined geometry and properties established by the materials used to manufacture the equipment. However, the sportsperson typically uses these over a wide range of conditions rather than a narrow range that provides constraints on the design of conventional sports equipment. According to embodiments of the invention sports equipment are implemented with multiple elements within the shaft such that the stiffness of the item varies with induced flexure arising from use. As such under one range of motion the item exhibits stiffness characterized by a first Young's modulus and under a second range of motion the item exhibits stiffness characterized by a second Young's modulus. | 07-26-2012 |
