Abstract

A golf practice and training device which includes a longitudinal channel having a pair of parallel walls and a flat bottom surface, the walls and flat bottom having a straight line sensor and a right angle sensor, respectively, and a plurality of visual indicia designs disposed on a centrally sloped flat top surface extending from both ends, whereby the device allows a golfer to train and practice accurate putting.

Claims

1. A golf putting practice device comprising:

a guide member including

a flat base,

a pair of elongated vertically spaced apart and generally parallel side rails disposed along said flat base,

a plurality of visual indicia design angle lines disposed on said flat base,

a plurality of visual indicia design swing lines disposed on a top of one of said side rails, and

a sensor disposed in one of said side rails, said sensor connected to an electric source and walls of said side rails and said flat base, whereby when a putter head of a golf putter touches at least one surface of said walls or flat base the sensor indicates the necessity for correcting the swing of a practicing golfer.

2. The golf putting practice device of claim 1, wherein said front and rear walls have a "V" shaped top surface thereof for accommodating an arc-style swing track.

3. The golf putting practice device of claim 1, wherein a front wall is thicker than a rear wall for maintaining the plurality of visual indicia design swing lines thereon.

4. The golf putting practice device of claim 3, wherein said plurality of visual indicia design swing lines are symmetrically located at left and right top surfaces of said front wall for indicating back and finishing swing distances of the practicing golfer.

5. The golf putting practice device of claim 1, wherein said sensor further includes beam emitting sensors and beam receiving sensors for detecting when a putter head does not squarely cross with a surface of the flat base.

6. The golf putting practice device of claim 5, wherein said sensor is further connected to a buzzer for activating when the putter head of the golf putter does not squarely cross with the surface of said flat rectangular shaped base for correcting the swing of the practice golfer.

7. The golf putting practice device of claim 1, further including an induction lamp disposed on one of said side rails.

8. A golf putting practice device comprising:

a guide member including

a flat base,

a pair of elongated vertically spaced apart and generally parallel side rails disposed along said flat base,

a plurality of visual indicia design angle lines disposed on said flat base,

a plurality of visual indicia design swing lines disposed on a top of one of said side rails, and

beam emitting sensors and beam receiving sensors for detecting when a putter head does not squarely cross with a surface of the flat base.

9. The golf putting practice device of claim 8, further including an induction lamp disposed on one of said side rails.
