Abstract
Abstract The golf practice device disclosed utilizes a tethered golf ball for practicing or playing a simulated game of golf. A rotatable drum is mounted on a base and a tether secured to the golf ball is guided from the golf ball over a roller and pulley on the base to the rotatable drum where the tether is attached so it can be wound onto the drum and subsequently paid out from the drum when the golf ball is hit with a conventional golf club from a tee on the base. An adjustable brake is coupled to the rotatable drum to impose braking forces on the drum and a distance indicator coupled to the drum for rotation with the drum is used to measure the force with which the golf ball is hit. A hook and slice indicator having tether position sensing members located adjacent the roller and straddling the tether is actuated by the tether when the ball is hit to indicate the direction of flight of the ball. Both the distance indicator and the hook and slice indicator may be connected to an electrical display arrangement.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
227 words
A golf practice device comprising: a base; a drum member rotatably mounted on said base; a simulated golf ball; a flexible tether having first and second ends, the first end of said tether being attached to said golf ball and the second end of said tether being wound around and attached to said drum; a pulley mounted on said base, said tether passing over said pulley intermediate the first and second ends of the tether; a roller mounted on said base, said tether extending from said golf ball to said roller and thence to said pulley and said drum member; and direction indicating means for presenting an indication of the direction of flight of said golf ball on said tether with respect to said roller, said direction indicating means including an arm pivotally mounted to said base and tether position sensor members mounted to the pivotally mounted arm and extending from said arm to tether engaging positions adjacent said roller whereby said tether is engaged by said sensor members, adjacent said roller and the pivotally mounted arm and said sensor members are rendered positionally responsive to the position of said tether, said direction indicating means further including visual indication means coupled to the arm and responsive to the position of the pivotally mounted arm for manifesting the tether position detected by said arm and said sensor members.
Claim 2
Dependent Claim
227 words
A golf practice device comprising: a base; a drum member rotatably mounted on said base; a simulated golf ball; a flexible tether having first and second ends, the first end of said tether being attached to said golf ball and the second end of said tether being wound around and attached to said drum; a pulley mounted on said base, said tether passing over said pulley intermediate the first and second ends of the tether; a roller mounted on said base, said tether extending from said golf ball to said roller and thence to said pulley and said drum member; and direction indicating means for presenting an indication of the direction of flight of said golf ball on said tether with respect to said roller, said direction indicating means including an arm pivotally mounted to said base and tether position sensor members mounted to the pivotally mounted arm and extending from said arm to tether engaging positions adjacent said roller whereby said tether is engaged by said sensor members, adjacent said roller and the pivotally mounted arm and said sensor members are rendered positionally responsive to the position of said tether, said direction indicating means further including visual indication means coupled to the arm and responsive to the position of the pivotally mounted arm for manifesting the tether position detected by said arm and said sensor members.
Claim 3
Dependent Claim
44 words
Apparatus as defined in claim 1 further comprising: a disc mounted on said base and having distance indicia defined thereon; and movable pointer means operatively coupled to said drum member and cooperating with said disc for identifying the individual distance indicia on said disc.
Claim 4
Dependent Claim
31 words
Apparatus as defined in claim 2 further comprising: adjustable braking means mounted to said base and coupled to said drum member for imposing an adjustable braking force on said drum member.
Claim 5
Dependent Claim
25 words
Apparatus as defined in claim 3 wherein said adjustable braking means comprises an adjustable friction brake mounted to said base and contacting said drum member.
Claim 6
Dependent Claim
31 words
Apparatus as defined in claim 1 further comprising means coupled with said drum member for indicating a driving force transmitted from said simulated golf ball through said tether to said drum.
Claim 7
Dependent Claim
29 words
Apparatus as defined in claim 5 further including braking means mounted to said base and coupled to said drum member for imposing a braking force on said drum member.
Claim 8
Dependent Claim
34 words
Apparatus as defined in claim 6 wherein said means coupled with said drum member for indicating a driving force includes movable pointer means coupled to said drum member for rotation with said drum member.
Claim 9
Dependent Claim
38 words
Apparatus as defined in claim 7 wherein means bearing distance indicia is mounted fixedly to said base adjacent to and cooperating with said movable pointer means to provide a scale for measuring the magnitude of the driving force.
