Patent ID: 7674185

Claim:
A training device for swing development comprising: an elongated member having a pair of handles, one handle connected to each end of the elongated member, wherein said handles are rotatably connected to, and extend perpendicular to, said elongated member, said handles extending from said member in opposite directions to one another; said elongated member comprises a coiled spring having a pair of telescoping rigid elongated members connected thereto, one rigid elongated member fixedly connected to each end of said spring; wherein each of said pair of telescoping rigid elongated members comprises a pair of bars, an inner bar seated within an outer bar, said inner and outer bars adapted to be moved longitudinally in relation to each other and locked into place in a desired position relative to one another, a first said inner bar being connected at one end to a first coupling device and a second said inner bar being connected at one end to a second coupling device, one of said pair of handles being connected to said first coupling device and a second one of said pair of handles being connected to said second coupling device; each of said first and second coupling devices comprises a rotary bearing, said handles being connected to said rotary bearings of said coupling devices allowing free rotation of said handles within said coupling devices; and an attachment connected to said handle, said attachment rotating in conjunction with the rotary movement of the handle.
