Golf swing practice apparatus
First Claim
Patent Images
1. A golf swing measuring apparatus, comprising:
- a first sensor for providing a first signal when a first portion of a golf club head reaches a first location;
a second sensor for providing a second signal when said first portion of the club head reaches a second location spaced later in the swing from the first location by a longitudinal distance;
a third sensor for providing a third signal when a second portion of said club head reaches a third location spaced transversely by a lateral distance from said second location with respect to the club swing;
velocity calculating means for computing the velocity of the club head in response to inputs representing said longitudinal distance and the difference in time between the occurrence of said first signal and the occurrence of said second signal; and
face angle calculating means for computing the face angle of the club head in response to inputs representing said computed velocity, said lateral distance, and the difference in time between the occurrence of said second signal and the occurrence of said third signal.

Abstract
A measuring and display apparatus for discretely presenting various characteristics concerning a practice golf swing. These characteristics include velocity and face angle for a putting stroke and, for a fuller stroke, velocity, face angle (or alternatively, hand position), "sweet spot" miss, and path deviation. Photoelectric sensors in a portable cabinet are used in the full-swing apparatus, thereby avoiding use of sensors embedded in a mat, and hence subject to injury. The cabinet is conveniently supported by legs that are rotatable for use as a handle, thereby making the entire unit quite portable in one, relatively small unit.
