Patent ID: 8500569

Claim:
A golf swing training device, for use by a golfer to properly develop a golf swing and counter a tendency toward an overpowered back-swing resulting in an uncontrolled out-of-plane downswing, while simultaneously training correct club rotation during a downswing, said golf swing training device comprising: a strap, said strap having a first end and a second end; a latch plate, said latch plate being adjustably securable in proximity to said strap first end; a latch, said latch being secured to said second end of said strap and being configured to releasably receive a portion of said latch plate; at least one bungee cord, said at least one bungee cord having a first end and a second end, said first end of said at least one bungee cord being attached to said strap at a position relative to said latch, said at least one bungee cord further comprising a first cord portion and a second cord portion being joined to said first cord portion, said first cord portion having a first elastic modulus, and said second cord portion having a second elastic modulus, said second elastic modulus being greater than said first elastic modulus; and a cinching apparatus, said cinching apparatus being located proximate to said second end of said at least one bungee cord, and being configured for cinching of said at least one bungee cord around a portion of the shaft of the golf club to be on or proximate to the grip at a position being distal from the end of the shaft, to provide a lever-arm effect to counter a tendency toward an overpowered backswing and maintain a controlled in-plane downswing, and to pull the club rotation forward around the fulcrum of the wrist to simultaneously train correct club rotation during the downswing.
