## Abstract

A golf swing training apparatus designed to allow a golfer to practice full swing motions while actually hiring a golf ball. The device is light weight and of simple construction. It provides for optimization of practice time by allowing instant feedback as to progress, or the lack thereof, in the golfer's technique. The device monitors the lateral and forward leg and knee motion during the full swing motion. Moreover, the device provides swing plane indicator rods which may be positioned at any useful angle for a full range of golf swings.

## Claims

### Claim 1

A golf swing training apparatus comprising:
a) first and second spaced horizontal base supports;
b) first and second spaced vertical supports having top and bottom ends, said bottom ends of said vertical supports connected to said first and second spaced horizontal base supports respectively by first and second elbow joint means, said first and second elbow joint means each having the capacity to swivel about an axis along the length of each left and right vertical supports, said vertical supports further possessing the ability to adjust in length;
c) spaced upper and lower horizontal alignment bars, said alignment bars each having left and right ends, said lower alignment bar connected by its respective left and right ends to said first and second vertical supports above said elbow joint means, said upper alignment bar connected respectively near its left and right ends to said top ends of said first and second vertical supports;
d)first and second adjustable swing plane indicator rod L-joints; and
e) first and second swing plane indicator rods, each of said swing plane indicator rods having a length of about 3 to 4 feet, each of said swing plane indicator rods further having a first end, said first end of said first swing plane indicator rod connected to said first adjustable swing plane indicator rod L-joint, said first end of said second swing plane indicator rod connected to said second adjustable swing plane indicator rod L-joint, said first and second adjustable swing plane indicator rod L-joints further connected respectively to said left and right ends of said upper alignment bar, said L-joints further having the capacity to swivel about an axis along the length of said upper alignment bar.

### Claim 2 (depends on 1)
