US Patent 7140245 Wind vane for golfers

A wind vane that easily snaps on to golf equipment such as the pole of a golf bag for visually indicating wind direction to a golfer comprises two side elements attached to each other at a junction along the side elements' edges forming approximately a 50 degree angle between the side elements, and a partially opened cylindrical clamp. A ring holder is provided on the inside surface of each of the side elements. A plurality of ribbons extend from each of the ring holders and the movement of such ribbons indicate the direction and to some extent the speed of the wind. An alternate embodiment of the wind vane comprises arms that clip onto a canopy pole of a golf cart and a plurality of ribbons to indicate wind direction.
