ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates in general to a golf practice device, and more particularly, to an indoor/outdoor golf practice device having a spring assembly and a damper assembly which, among other things, cooperatively facilitate use of the device in confined environments without sacrificing requisite feel for appropriate feedback toward correcting and/or grooving of a golfer's swing.

U.S. Pat. No. 6,129,637 discloses a golf practice device comprising a base having on the top surface a section of artificial turf and a positioning support. A rod is pivot mounted to the front end of the positioning support and the leading end of the rod is pivot mounted to a ball to form the directional control mount. The rod of the directional control mount is inserted such that the ball enters a threaded section, at the bottom end of which is the connection rod of a swivel mount having an internal spherical-shaped space, and until the threaded section is situated laterally against the ball of the direction control mount. This enables assembly to the swivel mount so that the ball of the direction control mount is contained in the swivel fitting of the swivel assembly. The swivel mount and the connection rod at the top and bottom ends of the swivel assembly are structurally coordinated with a golf ball at the bottom end of another rod forming the golf ball assembly. Following the assembly of the device, while the user is engaged in golf club swinging practice, the invention purportedly offers increased practical performance by indicating to the user whether the golf club has hit the golf ball squarely or not and, furthermore, allows for appropriate corrections.
U.S. Pat. No. 5,865,683 discloses a golf practice device which comprises a rectangular base block, an “L” shaped metal supporting plate mounted on one side of the base block by nuts, a steel cantilever shaft having one end fixed to a vertical slot of the vertical portion of the supporting plate by a nut and a ball swinging rod having a mounting socket at the top for sleeving over the free end of the cantilever shaft and retained by a nut and a washer, and a target ball at a free end of the ball swinging rod.
U.S. Pat. No. 5,544,886 discloses a system for enabling golf practice to be held in a limited space including: a cylindrical, PVC, pipe casing containing weight means and having a first end with an end cap fastened thereon, an eye bolt fastened to the first end cap, and a second end having an end cap fastened thereon, forming a sealed container for the weight means, a golf ball having a bore formed therethrough at the diameter, the bore countersunk at one end, and a tethering cord having a first end and a second end, the cord secured at the first end to the golf ball, the cord passing through the bore and secured therein, and shaped to conform to the outer surface of the golf ball at the first end, and the tethering cord secured at a second end to the eye bolt, the second end passing through the eye bolt, and secured to itself by a clamp, thereby forming a loop, whereby when the golf ball, the cord and the pipe casing are strung out in alignment and the ball is struck by a golf club, the ball will travel along it natural trajectory until restrained by the weight pipe casing, thereby allowing viewing of at least the initial portion of the trajectory of the ball and enabling the ball to travel substantially double the distance of the length of the cord.
U.S. Pat. No. 5,056,790 discloses a golf practice device in which a practice ball is connected by a flexible cord to a ball-control frame mounted rotatably on a base, characterized in that: when the device is arranged operatively, the base is secured at a location at which a golf club may be swung to strike said ball, the flexible cord being substantially inelastic and acting, when the ball is struck, to effect rotation of the ball-control frame, the latter having damping means arranged to allow the cord to extend to an extent commensurate with the striking force on the ball.
U.S. Pat. No. 4,177,995 discloses a drag member having a flexible, self-sustaining form which is centrally attached to a golf ball by a flexible elongated member. The drag member comprises a substantially planar central portion and radial segments extending outwardly from the central portion. When the golf ball is driven through the air, the drag member is pulled behind the ball transverse to the trajectory of the ball. The drag member defines an aerodynamically designed drag surface area of initially fixed dimensions which vary inversely with the flight speed of the device. The drag member acts to shorten the flight of the golf ball and to provide a flight trajectory for the attached golf ball simil
