Patent ID: 8029381

Claim:
A golf swing improvement device to indicate a shift of a golfer's body weight during a golf swing, comprising: a lower housing having an opening disposed through a peripheral surface thereof; an upper housing movably coupled to the lower housing to receive the golfer's front foot; a contact switch disposed between the upper housing and the lower housing such that the contact switch is activated upon a predetermined compression of the upper housing with respect to the lower housing; a compression member disposed between the upper housing and the lower housing to create a biasing force between the upper housing and the lower housing such that when the golfer initiates the golf swing, the biasing force withstands a first pressure from the golfer's front foot to prevent activation of the contact switch, and when the golfer's body weight shifts during a down swing, the biasing force is overcome by a second pressure from the golfer's front foot, greater than the first pressure, to enable activation of the contact switch; and an adjustment lever movably disposed within the opening to contact the compression member such that the biasing force is changed when the adjustment lever is moved within the opening.
