ABSTRACT:
A golf training device includes base pad on which an anchoring base is fixed. The anchoring base has a primary column and a secondary column extending upright therefrom and each defining therein a bore. An L-shaped support has a first section movably received within the bore of the primary column and a second section extending transversely from the first section to define a cantilever. A secondary support bar extends from the second section of the L-shaped support to be movably received within the bore of the secondary column. A dummy ball assembly includes a spherical member and two suspension rods having lower ends connected to and extending from the spherical member in a diverging manner to upper ends to define a V shape. A tubular member connects between the upper ends of the suspension rods. The tubular member has a central bore to slidably fit onto the second section of the L-shaped support so as to rotatably suspend the spherical member under the second section of the support and to allow relative moment of the dummy ball assembly with respect to the support by means of bearing. A helical spring is fit onto the second section and located between each of the suspension rods and a fixed portion of the second section in an un-loaded condition for counteracting a component of an external force applied thereon along a direction parallel with the second section.
