ABSTRACT:
A baseball swing training apparatus comprised of upper and lower platform members that are rotatably secured to one another by means of a bearing plate assembly. The platform members have a generally rectangular body with at least one side of each platform member formed as an extending finger portion. The extending finger portion of the upper platform member receives thereon a spring loaded foot mechanism. The spring loaded foot mechanism is comprised of a continuous cylindrical member having upper and lower U-shaped ends, the upper and lower ends being orthogonal to one another and forming an L-shaped continuous cylindrical member. A coiled spring member is secured to the upper platform member and to the upper U-shaped end by a hook shaped element. The coiled spring member is secured to the upper platform member by an elongated rod, the ends of which are received within apertures defined by the coiled spring. The ends of the rod are in turn received within an eye portion of spaced apart eyebolts.
