Abstract
Abstract This invention consists of an electrically actuated device consisting of a platform on which a golfer stands and a pad having a pressure actuated tee, adapted to support a golf ball; the platform includes a pair of oppositely, normally upwardly angled, pivotal leaf or blade portions for engagement by a golfer's heels. Electric components are associated with a control box, providing a plurality of switches, the pair of leaf portions and the pressure actuated tee to activate a light, associated with said tee, to indicate to the golfer when he has or has not accomplished a proper weight shift. Elements are also provided to adjust the tee pad relative to the platform to accommodate each individual golfer. An additional member in the form of a shield, is provided to assist the golfer in developing a correct inside to outside, or through, swing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
217 words
A golf swing practice device comprising: a. a platform member providing 1. blade means, engable by the right heel and the left heel of a golfer positioned to swing a golf club; b. an enlarged pad including a tee to receive a ball, said tee providing 1. a pressure actuated electric switch calibrated to be activated by the weight of a golf ball, and 2. electric light means; c. electric power means including a source of electric power and electric circuitry including manually operable switch means associated with the heel actuated blade means and the golf ball pressure actuated switch whereby as the back swing progresses the weight of the golfer is shifted off of the left heel onto the right foot and then as the ball impacting swing progresses the left heel goes down and as the swing progresses the right heel is elevated to release the right foot actuated switch to activate the tee light just prior to the golf club arriving at a ball impacting position over the tee to indicate that a desirable golf swing is being made. d. control means for said electric circuitry, including a plurality of electric control switches, whereby the tee light may be activated in a plurality of different modes, with or without a ball on the tee.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
31 words
The device as defined in claim 1 including adjustable connection means between said platform and tee pad to adjust the spacing and angularity of said tee pad forwardly of said platform.
Claim 4
Dependent Claim
50 words
The device as defined in claim 2 wherein said connection means comprises a first bar, adjustably carried by said platform and including a plurality of calibrations along its length extending forwardly from said platform to a point of pivotal connection to a second bar, adjustably, connected longitudinally of said pad.
Claim 5
Dependent Claim
63 words
The device as defined in claim 1 wherein said blade means comprises aa pair of aligned oppositely extending, normally upwardly inclined, diverging blades, hinged to said platform along their confronting ends in respective grooves formed in the upper surface of said platform, each of said blades being positioned for engagement by one of the heels of a golfer in a conventional golf stance.
Claim 6
Dependent Claim
24 words
The device as defined in claim 4 wherein each of said blades is normally urged to said upwardly inclined position by a compression spring.
Claim 7
Dependent Claim
41 words
The device as claimed in claim 5 wherein said electric switch means comprises electric switches positioned in said grooves beneath the respective blades for sequential engagement thereby when the weight shift on the heels sequentially depresses said blades against said springs.
Claim 8
Dependent Claim
40 words
The device as defined in claim 6 wherein the electric switch, positioned beneath the blade engaged by the right heel of a golfer is adjustable upwardly and downwardly and includes means extending outwardly of said platform to accomplish said adjustment.
Claim 9
Dependent Claim
35 words
The device as defined in claim 1 wherein said plurality of electric control switches comprises four switches located on a control box, remotely located relative to said platform and pad and comprising said control means.
Claim 10
Dependent Claim
20 words
The device as defined in claim 8 including electric conductor conduit means connecting between said control box, platform and pad.
