Golf club swing training device

Claim 1

A training device which defines for golfers an impact zone and the proper orientation of the club head and the club head face in the impact zone, said device consisting of: (a) a body made from flat rigid materials and being of T-shape formed by two straight arms extending at right angles from opposite sides of a first end of a straight bar-shaped leg, the edges of said arms farthest from the second end of said leg being straight and aligned to define a first visible straight line to be positioned adjacent to a ball and between the golfer and the ball and to be substantially aligned with the desired direction of ball travel to indicate the direction the club head should go in the impact zone, the outer ends of said arms forming visible ends appropriately spaced to define an impact zone, said leg defining a second visible straight line to be positioned between the golfer and the ball, the second line generally bisecting said first line and being at right angles to said first line, said second line to extend toward the ball to thereby indicate the direction the club face should parallel in striking the ball, (b) means for pivotally connecting said arms at their inner ends to said leg so that they can be pivoted to a collapsed position aligned with said leg for carrying and storing, and means to secure said arms in collapsed and spread positions, said first end of said leg forming a straight line at 90° to said second line to assist in aligning said arms to form said first line at 90° to said second line, (c) said leg having double the width of each arm so that said arms can store side-by-side on said leg in their collapsed positions, said inner ends of said arms actually physically abutting when said arms are aligned in their spread positions to form said first line, the pivotal connection of each arm to said leg being located at the center of a square defined by the width of the arm and an equal distance from the inner end of the arm, each arm at its inner end being relieved on a line extending from a point thereon defined as a point substantially midway between the centers of pivotal connection of said arms to said leg to the adjacent outer edge of said leg when viewed with the arms aligned at 90° to said leg, whereby said arms will not interfere with each other in moving to collapsed position of said arms, and (d) indicia on the upper face of said leg instructing the golfer in usage including indicating substantially aligning said first line with the desired direction of ball travel and indicating moving said club head parallel to said first line in striking said ball while maintaining said club head face parallel to said second line.
