Abstract

A golf club angular orientation indicating device includes an indicator housing, a switch plate and a shaft clamp. The shaft clamp is slidably received by the indicator housing. An orientation bore is formed in the indicator housing to receive the switch plate. The switch plate is retained on one end by the indicator housing and on the other end by a power plate. The switch plate includes at least two tilt switches mounted on at least two spring loaded pivot plates. A hold down bolt is used to adjust the angular orientation of the at least two tilt switches. Power is preferably supplied to the at least two tilt switches through at least one battery and an on-off switch. Closing the circuit of the at least two tilt switches will supply power to a light emitting device and/or a sound emitting device.

Claims

1. A method which allows a golfer to start a golf club swing at a particular angular orientation, comprising the steps of:

providing a two dimensional level;

retaining pivotally said two dimensional level in a housing;

attaching said housing to a shaft of a golf club;

providing a source of electrical power to operate said two dimensional level;

setting a golf club to a start angle of swing;

setting said two dimensional level to an angle by pivoting thereof according to said start angle of swing;

providing the capability of an alert when the golf club is in the proper angular orientation; and

providing at least two spring loaded pivot plates mounted to a plate and mounting a single tilt switch to each one of said at least two spring loaded pivot plates for said two dimensional level, decreasing accuracy of said two dimensional level by;

increasing the angle of said spring loaded pivot plates relative to said plate.

2. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 1, further comprising the step of:

providing the capability of diminishing the accuracy of said two dimensional level through adjustment.

3. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 1, further comprising the step of:

providing at least two tilt switches mounted to a plate for said two dimensional level.

4. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 2, further comprising the step of:

enabling the adjustment of the accuracy of said two dimensional level by rotating an adjustment nut.

5. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 1, further comprising the step of:

providing said alert with a sound emitting device.

6. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 1, further comprising the step of:

providing said alert with a light emitting device.

7. A method which allows a golfer to start a golf club swing at a particular angular orientation, comprising the steps of:

providing a two dimensional level, the accuracy of said two dimensional level capable of being diminished through adjustment;

retaining pivotally said two dimensional level in a housing;

attaching said housing to a shaft of a golf club;

providing a source of electrical power to operate said two dimensional level;

setting a golf club to a start angle of swing;

setting said two dimensional level to an angle by pivoting thereof according to said start angle of swing;

providing the capability of an alert when the golf club is in the proper angular orientation; and

providing at least two spring loaded pivot plates mounted to a plate and mounting a single tilt switch to each one of said at least two spring loaded pivot elates for said two dimensional level, decreasing accuracy of said two dimensional level by increasing the angle of said spring loaded pivot plates relative to said plate.

8. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 7, further comprising the step of:

providing at least two tilt switches mounted to a plate for said two dimensional level.

9. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 7, further comprising the step of:

enabling the adjustment of the accuracy of said two dimensional level by rotating an adjustment nut.

10. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 7, further comprising the step of:

providing said alert with a sound emitting device.

11. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 7, further comprising the step of:

providing said alert with a light emitting device.

12. A method which allows a golfer to start a golf club swing at a particular angular orientation, comprising the steps of:

providing at least two tilt switches mounted to a plate to form a two dimensional level;

retaining pivotally said two dimensional level in a housing;

attaching said housing to a shaft of a golf club;

supplying said at least two tilt switches with a source of electrical power;

setting a golf club to a start angle of swing;

setting said two dimensional level to an angle by pivoting thereof according to said start angle of swing;

providing the capability of an alert when the golf club is in the proper angular orientation; and

providing at least two spring loaded divot plates mounted to said slate and mounting a single said tilt switch to each one of said at least two spring loaded pivot plates, decreasing accuracy of said two dimensional level by increasing the angle of said siring loaded pivot plates relative to said plate.

13. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 12, further comprising the step of:

enabling the adjustment of the accuracy of said two dimensional level by changing the angle of said at least two spring loaded plates.

14. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 12, further comprising the step of:

providing said alert with a sound emitting device.

15. The method which allows a golfer to start a golf club swing at a particular angular orientation of claim 12, further comprising the step of:

providing said alert with a light emitting device.
