Benefits of technology

[0014]There are many benefits due to the swing pad pad. One benefit is that the sweet spot is generally larger due to the addition of the swing pad pad as compared to a golf club head without the swing pad. This results in golfers achieving a better ball flight, distance and result. Another benefit is that the golf club with the swing pad on the back of the striking face of the golf club head feels better at impact, primarily due to the additional mass of the swing pad behind the impact point as compared to a golf club without the swing pad. In some embodiments, weight can be removed from the striking face of the club head without sacrificing feel. This is due to the presence of the swing pad behind the impact point, which allows the area surrounding the swing to be thinner. The removed material can be placed elsewhere to improve other characteristics of the club head. In some embodiments where the swing pad has a uniform thickness, this constant thickness may further enhance the feel of the golf club by providing a constant sensation for the majority of ball strikes, because the majority of ball strikes for a given golfer or group of golfers of a given skill level would occur within or near the swing pad zone.
[0016]Another benefit of the swing pad is durability. Because most of the impact for a given golfer or group of golfers of a given skill level occurs in the swing pad zone, the extra mass and material of the swing pad gives the golf club head more durability in the area of the golf club head that receives the most impact. This enhanced durability of the swing pad zone of the striking face allows the rest of the striking face to be thinner, as compared to a golf club head with a constant face thickness. As a result of the rest of the striking face being thinner, for example, to less than 3.1 mm, the material savings can be shifted to other areas of the golf club head. For example, material can be shifted to the sole of the club to lower the center of gravity (CG), or material can be shifted to the perimeter of the club to increase the moment of inertia (MOI), of the club head.

Problems solved by technology

However, difficulty of use also increases with a decrease in loft angle and an increase in club length.
Because blade and muscle back designs have a small sweet spot, which is a term that refers to the area of the face that usually results in a desirable golf shot upon striking a golf ball, these designs are relatively difficult to wield and are typically only used by skilled golfers.

Embodiment Construction

[0039]Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in any specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Furthermore, when numerical ranges of varying scope are set forth herein, it is contemplated that any combination of these values inclusive of the recited values may be used.

[0040]FIGS. 1A, 1B and 1C are a series of diagrams showing the impact pattern for a 5 iron 1, 8 iron 2 and a pitching wedge 3. Diagrams 1, 2 and 3 are impact pattern data plots based on research conducted for various golfers of varying skill. Each point (representational points 4, 5 and 6) on diagrams 1, 2 and 3 indicate the impact location of the ball with the striking face of the golf club head for one golf swing with the specifi...

Abstract

A set of progressive golf clubs with an elliptical pad construction on the back of the striking face that corresponds to a location, shape and size of a predetermined golfer's impact pattern for the lofts and lengths of each of the golf clubs in the set. The elliptical pad progressively changes in location, shape and size from the long irons, to the mid irons, to the short irons, and to the wedges, based on the location, shape and size of a predetermined golfer's impact pattern for each of the long irons, mid irons, short irons, and wedges.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 368,228, filed Jul. 27, 2010, which is incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]Certain embodiments discussed herein relate to a set of progressive golf clubs, and, more particularly, the present invention relates to a set of progressive golf clubs heads with a swing pad.BACKGROUND OF THE INVENTION[0003]Golf club heads come in many different forms and makes, such as wood- or metal-type, iron-type (including wedge-type club heads), utility or specialty-type, and putter-type. Each of these types has a prescribed function and make-up. The present invention will be discussed as relating to iron-type clubs, but the inventive teachings disclosed herein may be applied to other types of clubs.[0004]Iron-type golf club heads generally include a front or striking face, a back, a toe, a heel, a top line, a hosel, and a sole. The front face ...
