Electronic device for signaling wrist position during a golfer's swing
First Claim
1. A device adapted to be attached to and used on the back of a golfer'"'"'s hand for use by a golfer to signal a selected angular wrist roll and wrist bend during the swing of a golf club, said device comprising:
- a housing having a top surface and a bottom surface and defining in internal cavity;
a strap connected to said housing adapted for fastening said housing on a back of a hand of the golfer proximate a wrist whereby when worn by the golfer said housing moves according to movement of the wrist, said strap having a longitudinal axis adapted for extending around the golfer'"'"'s hand;
a first disk mercury switch mounted within said cavity at a center of said cavity and in a plane parallel to said bottom surface of said housing, said first disk mercury switch responsive to angular movement of the wrist;
a second disk mercury switch mounted within said cavity in a plane perpendicular to said bottom surface of said housing, said second mercury switch so as to be responsive to angular movement of said housing in a direction perpendicular to movement for actuating said first disk mercury switch whereby wrist roll and wrist bend during the swing provides movement of said first and second disk mercury switches;
each said first and second disk mercury switch having a disk cavity with a circular perimeter, a plurality of equally-spaced internal peripheral electrical contacts extending into said disk cavity, and a mercury pool within said disk cavity movable around said circular perimeter for contacting at least two adjacent of said electrical contacts during a rotation of said disk mercury switches around a center of said disk mercury switches;
an electrical power source within said cavity connectable to said first and second disk mercury switches;
a selector switch within said housing for selectively connecting and disconnecting said electrical power source to at least one of said first and second disk mercury switches, said selector switch operable by the golfer from exterior said housing; and
an audible signal producing means within said cavity connected in series with said electrical power source and at least one of said disk mercury switches whereby, when said at least one disk mercury switch is closed, said audible signal producing means is actuated to provide an audible signal to the golfer that the selected wrist orientation is achieved during the swing of the golf club.

Abstract
A device for positioning on the back of a golfer'"'"'s hand to provide the golfer with an audible signal when the golfer'"'"'s wrist has a selected angular orientation during critical portions of the swing of a golf club. The device includes a pair of multicontact orientation sensitive switches, with separate or joint connection provided, such that internal electrical connections are made only when the desired angular orientation of the wrist is achieved. When such connection is made, the circuit of the device provides an audible signal that is heard by the golfer. This proper wrist orientation, and the electrical connection, must be maintained during the golf swing in order to continue the audible signal. A change in the signal indicates that the preferred orientation is not maintained. The orientation switches are disk mercury switch units having twelve internal contacts positioned at thirty degree intervals. These switches are positioned within a housing with an orientation such that the electrical contacts are made when proper wrist orientation and club swing are achieved.

1. A device adapted to be attached to and used on the back of a golfer'"'"'s hand for use by a golfer to signal a selected angular wrist roll and wrist bend during the swing of a golf club, said device comprising:
-
a housing having a top surface and a bottom surface and defining in internal cavity; a strap connected to said housing adapted for fastening said housing on a back of a hand of the golfer proximate a wrist whereby when worn by the golfer said housing moves according to movement of the wrist, said strap having a longitudinal axis adapted for extending around the golfer'"'"'s hand; a first disk mercury switch mounted within said cavity at a center of said cavity and in a plane parallel to said bottom surface of said housing, said first disk mercury switch responsive to angular movement of the wrist; a second disk mercury switch mounted within said cavity in a plane perpendicular to said bottom surface of said housing, said second mercury switch so as to be responsive to angular movement of said housing in a direction perpendicular to movement for actuating said first disk mercury switch whereby wrist roll and wrist bend during the swing provides movement of said first and second disk mercury switches; each said first and second disk mercury switch having a disk cavity with a circular perimeter, a plurality of equally-spaced internal peripheral electrical contacts extending into said disk cavity, and a mercury pool within said disk cavity movable around said circular perimeter for contacting at least two adjacent of said electrical contacts during a rotation of said disk mercury switches around a center of said disk mercury switches; an electrical power source within said cavity connectable to said first and second disk mercury switches; a selector switch within said housing for selectively connecting and disconnecting said electrical power source to at least one of said first and second disk mercury switches, said selector switch operable by the golfer from exterior said housing; and an audible signal producing means within said cavity connected in series with said electrical power source and at least one of said disk mercury switches whereby, when said at least one disk mercury switch is closed, said audible signal producing means is actuated to provide an audible signal to the golfer that the selected wrist orientation is achieved during the swing of the golf club. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A device adapted for attachment and use on a back surface of a golfer'"'"'s hand for use by a golfer to signal a selected angular wrist roll and wrist bend throughout the swing of a golf club, said device comprising:
-
a housing having a top surface and a bottom surface and defining an internal cavity; an elastic strap connected to said housing adapted for fastening said housing on a back of a hand of the golfer proximate a wrist whereby when worn by the golfer said housing moves according to movement of the wrist, said strap having a longitudinal axis adapted for extending around the hand; a first disk mercury switch mounted within said cavity at a center of said cavity in a plane parallel with said bottom surface of said housing, said first disk mercury switch responsive to angular movement of said housing due to angular movement of the wrist, said first disk mercury switch having a disk cavity with a circular perimeter, a plurality of equally spaced internal peripheral contacts extending into said disk cavity, and a mercury pool within said disk cavity movable around said disk cavity perimeter contacting selected adjacent of said internal contacts; a second disk mercury switch mounted within said cavity in a plane perpendicular to said bottom surface of said housing, said second disk mercury switch responsive to angular movement of said housing in a direction perpendicular to movement for actuating said first disk mercury switch whereby wrist roll and wrist bend during the swing provides movement of said first and second disk mercury switches, said second disk mercury switch having a disk cavity with a circular perimeter, a plurality of equally spaced internal peripheral contacts extending into said disk cavity, and a mercury pool within said disk cavity movable around said circular perimeter contacting selected adjacent of said internal contacts; a battery power source within said cavity connectable to said first and second disk mercury switches; a selector switch within said housing for selectively connecting and disconnecting said battery power source to at least one of said first and second disk mercury switches, said selector switch operable by the golfer from exterior said housing; and an audible signal producing means within said cavity connected in series with said battery power source and at least one of said disk mercury switches whereby, when said at least one disk mercury switch is closed, said audible signal producing means is actuated to provide an audible signal to the golfer that the selected wrist orientation is achieved during the swing of the golf club. - View Dependent Claims (9, 10, 11, 12, 13)
