Abstract

A self contained gold training device designed to be integral with, or attached to and detached from the head of any golf club, gives a golfer an exact indication of the point of impact of the face of a golf club with a golf ball. The training device includes a housing which supports one or more impact sensitive transducers which generates an electric signal upon impact, an electronic circuit for determining if a transducer has received an impact, a display system responsive to the electronic circuit for signaling if a transducer has received an impact, a source of electrical power; and, in detachable systems, means for connecting and disconnecting the device to a golf club head. When attached to the head of a club, with the array of transducers on the face of the club, and swung into contact with a golf ball, the transducers generate a plurality of electrical signals which are transmitted to the electronic processor, and then to the display system which indicates the point of contact of the club face with the ball. In preferred embodiments there is an array of transducers, which, when they strike a golf ball, each generates a voltage which is proportional to the force exerted on that transducer by its impact with the ball. These voltages are in turn analyzed by an electronic circuit which then causes the display system to indicate the point of impact.

Claims

1. A self contained device for indicating the area of impact of the face of the head of a golf club with a ball, said face of said club having a predetermined impact center, the device comprising:

one or more impact sensitive transducer element which generates an electrical signal in response to an impact;

means responsive to an electrical signal generated by said one or more transducer elements, said responsive means linked to said one or more transducer elements, and;

means to signaling the area of impact of the face of the club with a ball, said signaling means being linked to and responsive to said means responsive to an electrical signal generated by said one or more transducer elements;

a single carrying unit, said impact sensitive transducer elements, said electrical signal responsive means, and said signaling means being carried by said single carrying unit; and

means for attachably and detachably locating said carrying unit carrying said one or more impact sensitive transducer elements, said signalling means, and said electrical signal responsive means on a golf club so that said one or more impact sensitive transducer elements, overlies the face of the club in a predetermined relationship to the impact center of the face of the club;

whereby, when the face of the head of a golf club impacts with a golf ball, an electrical signal is generated by said one or more impact sensitive transducer element to cause said electric signal responsive means to signal the area of impact of the face of the club with a ball.

2. The device of claim 1, wherein there is a single impact sensitive transducer element, and wherein said single transducer element is positioned to substantially overlie the impact center of the face of the club.

3. The device of claim 1, wherein their are two impact sensitive transducer elements, and wherein said two transducer elements are positioned substantially adjacent to, bracketing and equally spaced from the impact center of the face of the club.

4. The device of claim 1, wherein their are three transducer elements, and wherein said three transducer elements are positioned such that a first transducer element substantially overlies the impact center of the face of the club, and wherein the remaining two transducer elements are substantially adjacent to and bracketing said first transducer element.

5. The device of claim 1 wherein said signaling means is selected from the group consisting of visual display systems and audible display systems.

6. The device of claim 5, wherein said means for signaling the area of impact of the face of the club with a ball is a visual display system selected from the group consisting of light emitting diodes and liquid crystal displays.

7. The device of claim 5, wherein said means for signaling the area of impact of the face of the club with a ball is an audible display system, and wherein the audible display which is indicative of the area of impact of the face of the club is selected from the group consisting of pitch, duration and loudness, and combinations of pitch, duration and loudness.

8. The device of claim 1, wherein said one or more transducer element generates voltage when the face of the head of a golf club impacts with a golf ball, and said means responsive to an electrical signal generated by said one or more transducer element is an electronic circuit for monitoring the voltage generated by said one or more transducer element during impact to determine the point of impact.

9. The device of claim 1, wherein said device includes a self contained source of electric power.

10. The device of claim 9, wherein said self contained source of electric power is a battery.

11. The device of claim 1, wherein said electronic circuit includes means for resetting said signaling means after a predetermined period of time.

12. The device of claim 1, wherein said impact sensitive transducer element is a substantially thin, smooth and planar film.
