FIELDThe present disclosure generally relates to golf equipment, and more particularly, to ferrules for a golf club and methods to manufacture ferrules.
BACKGROUNDA golf club may include a shaft mounted to a hosel of a golf club head. A ferrule is typically included to help secure the shaft to the hosel and provide a smooth transition between the shaft and the hosel. Over repeated impacts, ferrules may loosen and begin to slide up the shaft, a phenomenon referred to as “ferrule creep,” which presents an eye sore to many golfers. Accordingly, there is a need for a ferrule with improved attachment means. The present disclosure seeks to satisfy this need.

In one example, the length 310 of the upper portion 210 may be greater than or equal to 0.500 inch (12.70 mm) and less than or equal 0.700 inch (17.78 mm). The upper portion 210 may have an upper end 212 defining a top opening 402 of the axial bore 400. In one example, the upper end 212 may be rounded with a radius of curvature greater than or equal to 0.030 inch (0.762 mm) and less than or equal to 0.050 inch (1.27 mm). The upper end 212 may define an upper outer diameter 320 of the upper portion 210. In one example, the upper outer diameter 320 may be greater than or equal to 0.360 inch (9.144 mm) and less than or equal to 0.560 inch (14.224 mm). The upper portion 210 may also include a lower annular ledge 214 configured to abut against a distal end 605 of the hosel portion 115. The lower annular ledge 214 may define a lower outer diameter 330 of the upper portion 210. In one example, the lower outer diameter 330 may be greater than or equal to 0.460 inch (11.684 mm) and less than or equal to 0.660 inch (16.764 mm). The lower outer diameter 330 may be greater than the upper outer diameter 320 and may be equal to an outer diameter 612 of the hosel portion 115 to provide a smooth transition between the shaft 120 and the hosel portion 115. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The transition portion 230 may extend downward from the upper portion 210 and may be disposed inward of the lower annular ledge 214 of the upper portion 210. The transition portion 230 may have a length 340 that may be less than or equal to 8% of the length 240 of the ferrule 140. In one example, the length 340 of the transition portion 230 may be greater than or equal to 0.020 inch (0.508 mm) and less than or equal to 0.040 inch (1.016 mm). The transition portion 230 may have an outer diameter that decreases toward the lower portion 220 from an upper outer diameter 350 to a lower outer diameter 360. In one example, the upper outer diameter 350 of the transition portion 230 may be greater than or equal to 0.380 inch (9.652 mm) and less than or equal to 0.580 inch (14.732 mm) and the lower outer diameter 360 of the transition portion 230 may be greater than or equal to 0.320 inch (8.128 mm) and less than or equal to 0.520 inch (13.208 mm). The transition portion 230 may have a funnel shape with a radius of curvature greater than or equal to 0.020 inch (0.508 mm) and less than or equal to 0.040 inch (1.016 mm) to mate with a complementary rounded edge 610 at the distal end 605 of the hosel portion 115.
