unusual versatility of structural designs of the golf clubs in accordance with the present invention specifically with respect to the area behind the club face with the unique configurations of various geometric shapes that best create a system that provides greater cushioning reduces or eliminates vibrations and shocks increases club head stability and is adaptable for all types of golf clubs a single or combination of various geometric structures can be used for the various types of iron golf club heads metalwood golf club heads putter heads and any other special type of golf club heads used in the game of golf this unique system substantially controls the kinetic energy produced when a golf club is used to strike a golf ball kinetic energy inherently travels in a linear direction or in a straight line kinetic energy is the main cause of vibration and shock waves that travel up a golf club shaft to the hands of the golfer this invention overcomes the negative or adverse effects of kinetic energy specifically the vibration and shock waves produced thereby by interrupting or effectively stopping its linear acceleration traveling up the hosel and shaft of the club this is accomplished by using various combinations and shapes of shock and vibration reduction elements in a cooperative manner in forms described in detail hereinbelow on the back surface of the club head these elements dramatically reduce the vibrations and shock waves and provide built in cushioning means on the club head the combination of these shock and vibration reducing elements not only creates a greater transfer of power at impact but provides a softer cushion and feel resulting in more accuracy and greater distance for a given swing effort as will become apparent.
