Abstract
Abstract A device for insuring that the striking surface of a sports implement is properly oriented prior to the initiation and completion of a contact swing. Two position orientation sensors are affixed to the shaft of the sports implement. One sensor senses the roll position of the striking surface, and the second sensor senses the pitch position of the striking surface. When both of these sensors indicate that the striking surface is properly oriented, an audible signal is generated. This signal is maintained for as long as the striking surface is properly oriented.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
205 words
A device for use with a sports implement provided with a striking surface and a shaft for determining the proper orientation of the striking surface at the completion of the backswing of the sports implement, said device comprising: a housing adapted to be attached to said shaft of the sports implement; and a sensing circuit provided within said housing for sensing the orientation of the striking surface of the sports implement, said sensing circuit comprising: a source of power; a first position sensing means connected to said source of power for sensing the roll position of the striking surface; a second position sensing means connected to said source of power for sensing the pitch position of the striking surface; and signal means connected to said source of power and said first and second position sensing means for emitting a signal when both said first and second position sensing means indicate that the striking surface is in its proper orientation, said signal emitted when the sports implement is at rest after completion of the backswing but prior to the initiation of the swing of the sports implement, wherein the striking surface is repositioned after the completion of the backswing until said signal means emits a signal.
Claim 2
Independent Claim
205 words
A device for use with a sports implement provided with a striking surface and a shaft for determining the proper orientation of the striking surface at the completion of the backswing of the sports implement, said device comprising: a housing adapted to be attached to said shaft of the sports implement; and a sensing circuit provided within said housing for sensing the orientation of the striking surface of the sports implement, said sensing circuit comprising: a source of power; a first position sensing means connected to said source of power for sensing the roll position of the striking surface; a second position sensing means connected to said source of power for sensing the pitch position of the striking surface; and signal means connected to said source of power and said first and second position sensing means for emitting a signal when both said first and second position sensing means indicate that the striking surface is in its proper orientation, said signal emitted when the sports implement is at rest after completion of the backswing but prior to the initiation of the swing of the sports implement, wherein the striking surface is repositioned after the completion of the backswing until said signal means emits a signal.
Claim 3
Dependent Claim
22 words
The device in accordance with claim 1 wherein said signal means produces an audible signal when the striking surface is properly oriented.
Claim 4
Dependent Claim
37 words
The device in accordance with claim 1 wherein said signal device emits a continuous signal whenever and as long as said first and second position sensing means indicate that the striking surface is in its proper orientation.
Claim 5
Dependent Claim
69 words
The device in accordance with claim 1 wherein each of said first and second position sensing means is provided with a switch consisting of: an enclosure; two energizable wire contacts provided within said enclosure; and a movable metal ball provided within said enclosure, wherein each of said balls moves within its respective enclosure and comes into contact with its respective wire contacts when said striking surface is properly oriented.
Claim 6
Dependent Claim
22 words
The device in accordance with claim 1 wherein said first position means and said second position means are electrically connected in series.
Claim 7
Dependent Claim
20 words
The device in accordance with claim 1 wherein said housing is angularly adjustable on the shaft of said sports implement.
Claim 8
Independent Claim
205 words
A device in combination with a golf club provided with a striking surface and a shaft for determining the proper orientation of the striking surface at the completion of the backswing of the golf club, said device and golf club comprising: a housing attached to the shaft of the golf club; and a sensing circuit provided within said housing for sensing the orientation of the striking surface of the golf club, said sensing circuit comprising: a source of power; a first position sensing means connected to said source of power for sensing the roll position of the striking surface; a second position sensing means connected to said source of power for sensing the pitch position of the striking surface; and signal means connected to said source of power and said first and second position sensing means for emitting a signal when both said first and second position sensing means indicate that the striking surface is in its proper orientation, said signal emitted when the golf club is at rest after completion of the backswing but prior to the initiation of the swing of the golf club, wherein the striking surface is repositioned after the completion of the backswing until said signal means emits a signal.
Claim 9
Independent Claim
205 words
A device in combination with a golf club provided with a striking surface and a shaft for determining the proper orientation of the striking surface at the completion of the backswing of the golf club, said device and golf club comprising: a housing attached to the shaft of the golf club; and a sensing circuit provided within said housing for sensing the orientation of the striking surface of the golf club, said sensing circuit comprising: a source of power; a first position sensing means connected to said source of power for sensing the roll position of the striking surface; a second position sensing means connected to said source of power for sensing the pitch position of the striking surface; and signal means connected to said source of power and said first and second position sensing means for emitting a signal when both said first and second position sensing means indicate that the striking surface is in its proper orientation, said signal emitted when the golf club is at rest after completion of the backswing but prior to the initiation of the swing of the golf club, wherein the striking surface is repositioned after the completion of the backswing until said signal means emits a signal.
Claim 10
Dependent Claim
25 words
The device and golf club in accordance with claim 7 wherein said signal means produces an audible signal when the striking surface is properly oriented.
Claim 11
Dependent Claim
40 words
The device and golf club in accordance with claim 7 wherein said signal device emits a continuous signal whenever and as long as said first and second position sensing means indicate that the striking surface is in its proper orientation.
Claim 12
Dependent Claim
72 words
The device and golf club in accordance with claim 7 wherein each of said first and second position sensing means is provided with a switch consisting of: an enclosure; two energizable wire contacts provided within said enclosure; and a movable metal ball provided within said enclosure, wherein each of said balls moves within its respective enclosure and comes into contact with its respective wire contacts when the striking surface is properly oriented.
Claim 13
Dependent Claim
25 words
The device and golf club in accordance with claim 7 wherein said first position means and said second position means are electrically connected in series.
Claim 14
Dependent Claim
23 words
The device and golf club in accordance with claim 7 wherein said housing is angularly adjustable on the shaft of the golf club.
