Abstract
Abstract The golf club swing training apparatus has a board on which the positions of the ball and the player's feet are designated for each club. It gives the player a scale of measurement for distances beween himself and the ball and between his feet for each club. It also gives the player the angles for his feet and the relative positions between the target foot and the off-target foot as closer to or farther from the ball. Flags or flexible strips are provided adjacent the ball positions to delineate the path of a club head in a proper inside-out swing. Means are provided to adjust the positions of the ball and the feet to accommodate players of different height and leg length as well as club shaft length. Rocker foot plates with associated signal means are provided to give the player a measurement of his body position on the backswing and the downswing to aid in holding his body without shift on the backswing and to shift the body toward the target on the downswing. The apparatus enables a player to measure his own positions and actions and enables an instructor to graphically demonstrate proper and improper positions and actions to a player.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
240 words
Apparatus for training a player to position his feet at the proper distance apart, at the proper angles, and at the proper locations relative to a ball for the club being used, comprising, a board a ball line on said board, a target foot position on said board lying at an angle between 10° and 30° to a line leading to (a) said ball line from a point off the inside of the heel of said target foot position, an off-target foot position on said board spaced from said target foot position lying at an angle of 0° to 12° to a line parallel to said ball line; a scale member on said board at said off-target foot position designating spaced locations of said off-target foot position for a particular club as to sidewise distance from said target foot position, the angle of said off-target foot position to a line parallel to said ball line, and the location of said off-target foot position ahead of, even with, and behind said target foot position; said foot positions being delineated by foot plates; longitudinal rocker means on said foot plates; said foot plates being rockable from side-to-side on said rocker means; positioning means on said board for angularly locating said rockable foot plates relative to said board and said ball line; and clicker signal means on said foot plates to advise the user of proper and improper rocking of said foot plates.
Claim 2
Dependent Claim
240 words
Apparatus for training a player to position his feet at the proper distance apart, at the proper angles, and at the proper locations relative to a ball for the club being used, comprising, a board a ball line on said board, a target foot position on said board lying at an angle between 10° and 30° to a line leading to (a) said ball line from a point off the inside of the heel of said target foot position, an off-target foot position on said board spaced from said target foot position lying at an angle of 0° to 12° to a line parallel to said ball line; a scale member on said board at said off-target foot position designating spaced locations of said off-target foot position for a particular club as to sidewise distance from said target foot position, the angle of said off-target foot position to a line parallel to said ball line, and the location of said off-target foot position ahead of, even with, and behind said target foot position; said foot positions being delineated by foot plates; longitudinal rocker means on said foot plates; said foot plates being rockable from side-to-side on said rocker means; positioning means on said board for angularly locating said rockable foot plates relative to said board and said ball line; and clicker signal means on said foot plates to advise the user of proper and improper rocking of said foot plates.
Claim 3
Dependent Claim
94 words
In apparatus as set forth in claim 1, means adjustably mounting said scale member on said board for moving the designated locations of said off-target foot position closer to and farther from said target foot position to provide for the various differences of tall, medium and short players; and means angularly adjustably mounting said target foot position relative to said ball line to provide various angles for said target foot position closer to and farther from parallelism to said ball line to vary the angulation of said target foot position to said ball line.
Claim 4
Dependent Claim
122 words
In apparatus as set forth in claim 1, ball position spots on said board on said ball line and a scale on said board designating positions of a ball for particular clubs relative to said foot positions; a mat on said board having a ball line and ball position spots overlying said ball line and ball position spots on said board; a club scale at said ball spots on said mat corresponding to said spots and scale on said board; and means adjustably mounting said mat on said board for moving the designated positions of a ball closer to and farther from said foot positions to provide for the various differences in shaft lengths and heights of tall, medium and short players.
Claim 5
Dependent Claim
133 words
In apparatus as set forth in claim 3, said mat having a first auxiliary scale lying parallel to said ball scale and spaced from said ball scale in the target direction and a second auxiliary scale lying parallel to said ball scale and spaced from said ball scale in the off-target direction; both said auxiliary scales having particular club designations in the same sequence as said ball scale; said club designations of said target side auxiliary scale lying farther from said foot positions and said club designations of said off-target auxiliary scale lying closer to said foot positions: said ball scale and said auxiliary scales for each club designation thereby defining a line at an inside-out angle as the path of a club head in the swing of a club at the ball.
Claim 6
Dependent Claim
81 words
In apparatus as set forth in claim 4, an upstanding member at said target side auxiliary scale and an upstanding member on said off-target side auxiliary scale; said upstanding members being movable on said auxiliary scales to locate them at selected ball and club designations; said upstanding members and a ball on said ball scale visually delineating to a player the path of the club head when traveling at an inside-out angle prior to, at, and after contact with a ball.
Claim 7
Dependent Claim
57 words
In apparatus as set forth in claim 5, a transverse projection on each said upstanding member; said transverse projections lying in the path of a club head when swung in an inside-out swing at a ball at said ball scale so as to be contacted by the club head in a proper swing on an inside-out angle.
