ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of golf, and more particularly to a novel golf club head having an interchangeable cartridge system wherein the golfer may select a cartridge with a golf ball striking surface of a particular density suited for the shot or control factors desired.
2. Brief Description of the Prior Art
During the play of golf, it is important that the golfer have control over the golf club head as it strikes the ball in order to have excellent performance. In using a putter, it is important that the club head have a ball-striking face or surface which provides the golfer a sense of touch and feel so that the ball may be putted with great accuracy. In the play of golf today, many improvements have been made to golf balls which have rendered the balls extremely hard and when struck by conventional putter contact faces or surfaces, the golfer may lose the feel for distance and touch around the target hole.
Therefore, a need has existed to provide a novel striking or contact surface or face for a putter club head which provides the golfer with a sense of touch and a feel for distance even tough hard covered balls are being struck. In some prior instances, a “balata” or soft face has been incorporated as an insert onto putter heads in order to obtain the proper feel on the face of the club head as a ball is struck. The golfer is then able to judge speed in an easier manner and will have better touch and better control over distance. Furthermore, by using a balata rubber face, the ball has a tendency to roll better and long putts end up closer to the cup and shorter putts will roll in.
However, difficulties and problems have been encountered when using club heads which are provided only with a soft or balata rubber insert which stem largely from the fact that the golfer has no way of changing or interchanging the rubber insert and therefore, must either have a multiplicity of putters in order to obtain the choice or selection of material density used at the striking surface. Therefore, a need has existed to provide a golf club head which has a striking surface or contact point which permits a changeable density material to be selectively incorporated into the club head to compensate for the speed of the greens.
SUMMARY OF THE INVENTION
Accordingly, the above problems and difficulties are avoided by the present invention which provides a novel golf club having a club head that will accept a plurality of interchangeable inserts or cartridges, each of which includes a material of different density. In one form of the invention, the club head includes a body having a front face formed with a recess or depression in order to insertably receive one of a selected cartridges. Means are provided for anchoring the cartridge to the body within the recess or depression. Each cartridge includes a material of a specific density and the cartridge includes a carrier for holding the material of specific density so that a portion of the material protrudes forwardly of the front face of the club head. Guide means are provided for registering the cartridge with the recess for easy insertion and removal. The anchoring means can include screws, fasteners, clips or other means of attachment. The material of controlled density resides in the carrier so as to provide an interchangeable cartridge and each cartridge will have different density-striking pads or material.
Therefore, it is among the primary objects of the present invention to provide a novel golf head for a golf club which will readily accept one of a plurality of selected cartridges wherein each cartridge includes a material of different density so that the golfer may have improved and better distance control when a golf ball is struck.
Another object of the present invention is to provide an interchangeable cartridge having different density-striking pads which may be detachably connected to the club head of a golf club.
Another object is to provide a golf head having a front fact with a depression or cavity for insertably receiving a selected insert from a group of inserts of which each insert is composed of different density-striking pads.
A further object of the present invention is to provide a putter club head adapted to receive an interchangeable cartridge selected from a group of cartridges having different density-striking pads.
A further object resides in an interchangeable cartridge having a pad of specific density which may be readily detachably to the front face of a club head by applying an adhesive, fasteners, hook and pile fastening or the like.
Still a further object resides in providing a club head striking pad carried on a disposable cartridge wherein the pad may be composed of silicon, foam, metals, soft or hard rubber or the like.
An object resides in providing a golf club head adapted to mount interchangeable striking pads or inserts to accommodate different golf course greens requiring different ball speeds.
Furthermore, by utilizing interchangeable striking inserts, a player may use his normal stroke to impart travel to the ball.
Also, manufacturers of putters with soft pads must make the pad last the life of the putter, which limits the range of different density materials whereas the interchangeable inserts or pads of this invention are disposable when worn and provide a full range of material densities from the softest to the very hardest.
