Abstract

A putting aid for use by golfers in improving putting strokes is releasably attachable to a golf clubhead and includes a parallelepiped housing for a ball and a plurality of angularly disposed pockets into which the ball rolls during a putting stroke. The pocket within which the ball comes to rest indicates whether the putter blade was held square with an intended line of putt during the stroke, or at an angle that causes the putt to be missed. The ball rolls into a wedge-shaped recess formed in a bottom wall of the housing. The recess has a pointed leading end that points toward the cup when the putting aid is properly attached to the putter, and a wide, arcuate trailing end within which the pockets are formed. The pockets are spaced so that a swing that is more than one degree off from a perfect swing is indicated by the ball rolling into a pocket positioned out of alignment with the pointed leading end of the recess. Properly executed strokes result in the ball rolling into the center pocket directly behind the pointed leading end. An embodiment including a mercury globule provides more detailed information.

Claims

1. A golf putting training aid, comprising:

a base member;

a wedge-shaped recess formed in said base member;

said recess having a bottom wall;

said recess having a narrow leading end and a wide trailing end;

attachment means for releasably attaching said base member to a putter so that said base member is oriented in a predetermined position relative to said putter;

said narrow leading end of said base member being disposed in leading relation to said wide trailing end of said base member during swinging of a putter toward a golf ball during a putting stroke, said orientation of said base member being said predetermined position;

a plurality of pockets formed in said bottom wall along the trailing end of said recess; and

a generally spherical ball positioned atop said bottom wall;

the structural characteristics of said recess and ball being such that a backswing of said putter having said base member secured thereto drives said spherical ball toward the leading end of the recess; and

the inertia of said spherical member causes it to roll into one of said pockets during said putting stroke of said putter so that a record is thereby created of the path of travel of said putter during said putting stroke.

2. The training aid of claim 1, further comprising a leveling means secured to said base member in transverse relation to a longitudinal axis of symmetry of said base member.

3. The training aid of claim 1, wherein said generally spherical ball is a solid spherical ball of rigid metallic construction.

4. The training aid of claim 1, wherein said generally spherical ball is a globule of mercury.

5. The training aid of claim 4, further comprising a plurality of small, closely spaced dimples formed in said bottom wall so that said globule of mercury leaves a trail of small mercury globules in each dimple over which it passes to thereby leave a history of its path of travel during a forward stroke of said putter.

6. The training aid of claim 1, further comprising a transparent closure member fixedly secured to said base member in overlying relation thereto to retain said generally spherical ball within said training aid and to permit viewing of said ball.

7. The training aid of claim 1, wherein said base member is of parallelepiped construction.

8. The training aid of claim 1, further comprising a plurality of divider walls that separate said pockets from one another.

9. The training aid of claim 1, wherein said pockets are circumferentially spaced about one degree apart from one another.

10. The training aid of claim 1, wherein said attachment means includes a magnet fixedly secured to said base member.

11. The training aid of claim 1 wherein said putter is a part of said training aid, and further comprising shim means, made of ferrous material fixedly secured to a preselected face of said putter, and wherein said attachment means includes a magnet fixedly secured to said base member.

12. The training aid of claim 1, wherein each of said pockets has a predetermined depth greater than a radius of said ball so that said ball remains in a pocket upon completion of a forward stroke of said putter.

13. A golf putting training aid of the type attached to a putter, comprising:

a base member of generally parallelepiped construction;

said base member having a bottom wall;

a wedge-shaped recess formed in said bottom wall, said recess having a pointed leading end and an arcuate trailing end;

a transparent top wall disposed in overlying relation to said base member;

a generally spherical ball member disposed in captured relation within said base member;

a plurality of recessed pocket members formed in said trailing end of said wedge-shaped recess;

each of said pocket members having a common, predetermined breadth;

a bubble level member disposed in transverse relation to said base member;

releasable fastening means for releasably mounting said base member to a preselected face of said putter; and

said pointed leading end of said recess being pointed in the direction of a target when the putter to which it is attached is swung.

14. The training aid of claim 13, wherein the plurality of pocket members is three and wherein said three pocket members are separated from one another by a pair of divider walls.

15. The training aid of claim 13, wherein the generally spherical ball member is of rigid, metallic construction.

16. The training aid of claim 13, wherein the generally spherical ball member is a globule of mercury, and wherein said globule of mercury has a diameter greater than said predetermined breadth of each of said pocket members.

17. The training aid of claim 16, further comprising a plurality of closely spaced, small dimples formed in said bottom wall.

18. The training aid of claim 13, further comprising a shallow depression formed in the leading end of said wedge-shaped recess.

19. The training aid of claim 18, wherein each of said pocket members has a depth slightly greater than a radius of said spherical ball member.
