Abstract

This invention creates a new and truly scientifically advanced design and structuring of golf club heads based on Sir Isaac Newton'"'"'s First Law of Motion. A very precise and controlled path of inertial swing is then developed by this gyroscopic club head. This is accomplished by utilizing a spherical metal weight positioned rearward of the striking surface. Further, a weight is positioned at the club head'"'"'s center of gravity. Further again, a metal spherical weight is positioned at the club head'"'"'s center of gravity. All this creates and results in a smooth, easy and natural flowing swing which is in one arc line and in one plane. The concept presented herein, enables the manufacture of unlimited variety of golf clubs.

Claims

1. A gyroscopic golf club head comprising:

a striking blade including a front striking area and a back surface located opposite to said front striking area;

said club having a predetermined center of gravity;

a threaded hole positioned on the back surface of the striking blade and substantially coincident with the center of gravity;

a spherical weight with a screw projecting therefrom and in line with the center of the spherical weight and being mounted on the back surface of the striking blade, said spherical weight being attached to said club head by said screw and being threadedly engaged within said threaded hole, said spherical weight being distanced substantially from surrounding club head material except at said attachment point between the screw and the threaded hole, in order to maximize the gyroscopic inertia of the golf club head in the “

swing”

motion of the golf club;

said club head including a hosel for the attachment of a golf club shaft.

2. The gyroscopic golf club head as recited in claim 1, wherein said screw extends outward at opposite ends of said spherical weight and through the geometric center of the spherical weight;

said club head comprising a semi-circular band, the width of which is less than the height of the striking blade and being attached to the ends of the striking blade at the back surface of the blade;

said spherical weight being rotatable and moveable along the length of the screw.

3. The gyroscopic golf club head as recited in claim 2 wherein the band comprises a threaded hole at the center of its arc and matching the threads of the screw and arranged in line with the hole at the back surface of the blade;

said screw at one end of the spherical weight being threaded in to the hole at the back surface of the blade and the opposite end of the screw being attached into the hole at the center of the arc of the band, whereby the spherical weight is positioned and rotatable on the screw between the back surface of the blade and the center of the band.

4. A gyroscopic golf club head as recited in claim 1, wherein said club head is selected from the group consisting of “

woods”

, “

irons” and

“

putters”

.

5. A gyroscopic golf club head as recited in claim 1,

comprising a bottom plate extending rearward from the bottom edge of the striking blade and having a center line perpendicular to a vertical line passing through the center of gravity of the striking blade;

a threaded hole on said center line, rearward from the striking blade, wherein the spherical weight, with the projecting screw, is threaded into said hole and mounted, in order to maximize the inertia of the golf club head in the “

swing”

motion of the golf club.

6. A gyroscopic golf club head as recited in claim 1,

wherein said spherical weight, positioned at the back surface of said striking blade, is less than 1.0″

from the center of gravity of the striking blade;

wherein said spherical weight is positioned and mounted on said striking blade, less than 1.0″

from the center of gravity, toward the the of said striking blade, in order to maximize the inertia of the golf club head, in the “

swing”

motion of the golf club.

7. A gyroscopic golf club head comprising:

a club head body including a striking “

face”

as the striking surface, said club head body having a predefined center of gravity;

a cavity located rearwardly of the back of said striking face and defined, at least in part, by said club head body;

a spherical weight having uniform means, positioned and attached within said cavity and spaced from said club head body such that the center of gravity of said spherical weight is substantially concentric with the center of gravity of said club head;

the density of the material, inside of the club head body, being less than the density of the material of the spherical weight, in order to maximize the inertia of the golf club head in the “

swing”

motion of the golf club;

said golf club head including a hosel for the attachment of a golf club shaft;

said golf club head selected from the group consisting of “

woods”

, “

mallets” and

“

irons”

.
