ABSTRACT:
A training device useful with a putter having a head and a shaft extending from the head has a sight line, which may be delineated by a taut string, and two rails for guiding the shaft as the putter is swung through a limited range defined by the rails. The limited range includes an intermediate position, in which the head of the putter is positioned in a lowermost position, a subrange of back-swing positions, in which the head of the putter is raised from the lowermost position, and a subrange of follow-through positions, in which the head is raised from the lowermost position. Each rail has a guiding surface. The rails are adapted to be adjustably curved into any of various configurations such that the shaft when guided along the guiding surfaces is positioned in a position farthest from the sight line when the putter is positioned in the intermediate position with the head positioned in the lowermost position and such that the shaft is positioned in positions closer to the sight line when the putter is swung through either subrange with the head raised from the lowermost position. The rails are arranged such that an imaginary line tangent to the guiding surfaces of the rails, in an imaginary plane intersecting the rails at any position within the limited range, is inclined approximately at a constant inclination relative to a horizontal plane. The rails are adjustable so as to adjust the constant inclination.
