Abstract
Abstract A golf practice device includes a solid golf ball which is mounted within a thin net of cords carried on the bottom end of a flexible cable. A spring connects to the top end of the cable to absorb the force when the ball is struck. The top end of the spring and cable assembly is supported to swing about the lower leg of a crank arm. The upper leg of the crank arm is supported for rotation on the frame of the device so that when the ball is hit the impact force is distributed between the cable and the crank arm. A pair of cord ends which hang below the ball drag on the ground to quickly stabilize the ball in hitting position for the next stroke.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
122 words
Apparatus for use to practice striking a ball, said apparatus comprising: support means for supporting the apparatus on a surface; a frame member on said support means extending above the surface; an arm member bent in a manner to provide upper and lower end portions that are vertically and horizontally offset from one another, said upper end portion being supported on said frame member to pivot about a first substantially horizontal axis; a vertically oriented suspension member supported on the lower end portion of said arm member to swing about a second substantially horizontal axis offset from and parallel to said first axis; a ball; and means for mounting said ball on said suspension member at a location below said second axis.
Claim 2
Dependent Claim
122 words
Apparatus for use to practice striking a ball, said apparatus comprising: support means for supporting the apparatus on a surface; a frame member on said support means extending above the surface; an arm member bent in a manner to provide upper and lower end portions that are vertically and horizontally offset from one another, said upper end portion being supported on said frame member to pivot about a first substantially horizontal axis; a vertically oriented suspension member supported on the lower end portion of said arm member to swing about a second substantially horizontal axis offset from and parallel to said first axis; a ball; and means for mounting said ball on said suspension member at a location below said second axis.
