US 7,727,080 B1 · Golf driver impact analyzer

Abstract

A golf swing analyzer providing a learning tool for golfers to help improve golf backswing and club face angle consistency. To gage the club angle relative to swing path, a fence is placed and held on the shaft perpendicular to the club face. During a golf swing, an air flow along this fence is created by the swinging motion of the club. For a perfect square shot, the pressures are equal on both sides of the fence; otherwise, as the fence angle changes relative to air flow, one side compacts the air, creating a high-pressure area while at the same time the opposite side dams the air flow and creates a low-pressure area. A differential pressure transducer detects this pressure difference on each side of the fence. When the ball is struck, a microphone in the device detects the ball impact and a microprocessor interprets the fence position relative to air flow based on the pressure transducer output. A microprocessor-driven speaker outputs a unique audio tone at the moment of ball impact which indicates whether the club face angle was open, closed or square, relative to the swing path.

Dependent claims

A golf club impact analyzer for a golf club having a shaft with a grip and a head with a striking face, said impact analyzer comprising:

a housing having a forwardly extending elongated generally planar fence defining a longitudinal intended line of flight, said housing being attachable to the golf club shaft just above the head of the golf club, said fence providing a visual alignment which, when aligned perpendicular to the striking face, corresponds to the intended line of flight;
said fence rigidly connected to said housing generally parallel to the longitudinal axis of the golf club shaft when said housing is attached to the shaft;
right and left air pressure sensors connected to said housing on the right and left, respectively, side of, and forwardly facing in the same direction as, said fence, each of said air pressure sensors producing a signal proportionally responsive to movement of air flowing therepast during each swing of the golf club;
an electronic circuit within said housing receiving the signals from each of said air pressure sensors producing a sensorially perceivable signal relative to alignment or misalignment between said stationary member and the direction of golf club head swing at the moment of impact of the golf club head with a golf ball.
