Abstract
A golf putting stroke trainer including an inertial sensor. The sensor is responsive to axial rotation and push-pull movement of the club face. The sensor is disposed in electrical communication with an alarm circuit. The trainer is positioned within a standard grip on the shaft of a putting club and provides a user-detectable signal if, during a putting stroke, the putter is rotated around the longitudinal axis of the shaft of the putter or moves in a direction parallel to the plane of the club face.
Claims7
A putting swing trainer comprising:
- a golf putter including an elongated shaft defining a first axis along the length thereof and a head mounted thereon having a ball striking surface defining a plane perpendicular to said first axis;
- an inertial sensor including a generally elongated arm having a length thereof disposed generally parallel to said first axis, said arm being supported on a pivot which is oriented in a direction perpendicular to said first axis and said plane so that improper movement of the putter including lateral movement of said putter along a second axis parallel to said plane or rotation about said first axis will cause relative rotation of the arm about the pivot;
- a detector associated with the sensor for indicating if said relative rotation of said arm about said pivot has occurred and for providing an alarm control signal in response thereto;
- and
- an alarm operative to receive the alarm control signal and to provide a detectable output in response so that the user is provided with an indication if improper movement of the putter occurs during the swing thereof.
