Abstract:
1. A golf swing trainer comprising: a ground alignment frame that lies essentially flat on the ground, the ground alignment frame comprising guide members including a straight, elongated front-back guide member generally perpendicular to a golfer's line of swing, and at least two straight, elongated fore-aft guide members connected at generally right angles to the front-back guide member generally parallel to one another and to a golfer's line of swing and spaced apart a distance sufficient to permit a golf club head to pass between them along the ground in the line of swing, the fore-aft guide members having free ends pointing in a swing direction to define an open-ended swing path along the ground, a first one of the at least two fore-aft guide members being connected to the front-back guide member with an adjustable connection enabling the first fore-aft guide member to be adjustably spaced from a second one of the fore-aft guide members on the front-back guide member to vary its parallel spacing relative to the second fore-aft guide member; and, a first tilt-adjustable upright guide member having a free upper end and having a lower end adapted to be connected to one of the ground alignment frame guide members with an adjustable tilt connection enabling the upright guide member to be connected at different locations and adjusted to different angles on the one of the ground alignment frame guide members and a second tilt-adjustable upright guide member adapted to be connected to one of the ground alignment frame guide members with an adjustable tilt connection enabling the second tilt-adjustable upright guide member to be connected to one of the ground alignment frame guide members in a manner spaced from and parallel to the first tilt-adjustable upright guide member to define a swing plane path for a golf club between them.
