Abstract

A device for producing a warning signal when a golf club is held with the longitudinal axis of the head thereof unparallel to the ground, or when the putter head undergoes any clockwise or counterclockwise rotation on the backstroke. The device includes a battery; signal structure for producing a signal when electrically energized; electrical circuit for electrically coupling the signal structure to the battery; and switch structure movable between an open position in which electrical energy is prevented from passing from the battery to the signal structure through the electrical circuit and a closed position in which electrical energy is allowed to pass from the battery to the signal structure through the electrical circuit to electrically energize the signal structure, the switch structure being in the closed position when the longitudinal axis of a golf club head is held at an angle unparallel to the horizon, or when the putter head undergoes any clockwise or counterclockwise rotation on the backstroke.

Claims

1. The combination with a golf putter of a signaling device, said golf putter including a putter head having a longitudinal axis and including a shaft having first end attached to said putter head and having a second end remote from said putter head for being gripped by a golfer;

said signaling device comprising;

(a) a source of electrical energy;

(b) signal means for producing a signal when electrically energized;

(c) electrical circuit means for electrically coupling said signal means to said source of electrical energy; and

(d) switch means inserted in said electrical circuit means and movable between an open position in which electrical energy is prevented from passing from said source of electrical energy to said signal means through said electrical circuit means and a closed position in which electrical energy is allowed to pass from said source of electrical energy to said signal means through said electrical circuit means to electrically energize said signal means, said switch means being in said closed position when said longitudinal axis of said putter head is held at an angle unparallel to the horizon or when said putter head undergoes any clockwise or counterclockwise rotation on the backstroke.

2. The combination of claim 1 in which said switch means includes a first switch means inserted in said electrical circuit means and movable between an open position in which electrical energy is prevented from passing from said source of electrical energy to said signal means therethrough and a closed position in which electrical energy is allowed to pass from said source of electrical energy to said signal means therethrough to electrically energize said signal means, said first switch means being in said closed position when said longitudinal axis of said putter head is angled upwardly relative to the horizon.

3. The combination of claim 2 in which said switch means includes a second switch means inserted in said electrical circuit means and movable between an open position in which electrical energy is prevented from passing from said source of electrical energy to said signal means therethrough and a closed position in which electrical energy is allowed to pass from said source of electrical energy to said signal means therethrough to electrically energize said signal means, said second switch means being in said closed position when said longitudinal axis of said putter head is angled downwardly relative to the horizon.

4. The combination of claim 3 in which said signaling device includes a body for being attached to said putter head;

in which said first switch means includes a mercury switch attached to said body; and

in which said second switch means includes a mercury switch attached to said body.

5. The combination of claim 4 in which said signal means includes a master switch for producing a visible signal when electrically energized.

6. The combination of claim 5 in which said switch means includes a master switch inserted in said electrical circuit means and movable between an open position in which electrical energy is prevented from passing from said source of electrical energy to said signal means and a closed position in which electrical energy is allowed to pass from said source of electrical energy therethrough.

7. The combination of claim 6 in which said master switch is a single pole, single throw switch.

8. The combination of claim 6 in which said light means is a light emitting diode.
