Abstract

Embodiments of golf club heads with loft-based weights and methods to manufacture golf club heads are generally described herein. Other embodiments may be described and claimed.

Claims

exact text as granted — not AI-modified
1 . A club head comprising:

       2 . A club head as defined in  claim 1 , wherein the distance comprises at least one of a distance being inversely proportional to the loft angle in a linear manner or a distance being inversely proportional to the loft angle in a non-linear manner. 
   
   
       3 . A club head as defined in  claim 1 , wherein the distance comprises a distance defined by the equation of ((−0.086 * θ)+3.797)≧x ≧((−0.086 * θ)+2.797), x is units of inches and θ is units of degrees. 
   
   
       4 . A club head as defined in  claim 1 , wherein the distance comprises a distance defined by the equation of x=(−0.086 * θ) +3.297, x is units of inches and θ is units of degrees. 
   
   
       5 . A club had as defined in  claim 1 , wherein the distance comprises a distance defined by the equation of x=(0.009 * θ̂2)+(0.194 * θ)+1,192, x is units of inches and θ is units of degrees. 
   
   
       6 . A club head as defined in  claim 1 , wherein the weight comprises at least one of a weight integrated into the body or an adjustable weight. 
   
   
       7 . A club head as defined in  claim 1 , wherein the weight comprises at least one or more weight located at or proximate to to bottom wall portion. 
   
   
       8 . A club head as defined in  claim 1 , wherein the weight comprises at least one of an elliptical shape, a circular shape, a polygonal shape, or a free-formed shape. 
   
   
       9 . A club head as defined in  claim 1 , wherein the weight comprises a weight associated with a mass of at least 48 grams. 
   
   
       10 . A club head as defined in  claim 1 , wherein the weight comprises a weight associated with dimensions of 2.3 inches long, 1.5 inches wide, and 0.3 inches thick. 
   
   
       11 . A club head as defined in  claim 1 , wherein the club head comprises at least one of a driver-type golf club head, a fairway wood-type golf club head, a hybrid-type golf club head, an iron-type golf club head, a wedge-type golf club head, or a putter-type golf club head.

       26 . A golf club comprising:
 a grip;   a shaft having a first end and a second end, the shaft coupled to the grip at the first end; and   a club had having a top end, a heel end, a front end, a back end, a top wall portion, a bottom waIl portion, and a face portion associated with a loft angle, the loft angle defined by a loft plane and a front end plane perpendicular to a ground plane; and   a weight positioned at or proximate to a distance relative to the front end plane, the weight positioned along an axis extending between the front and back ends,   wherein the distance is inversely proportional to the loft angle.   
   
   
       27 . A golf club as defined in  claim 26 , wherein, the distance comprises at least one of a distance being inversely proportional to the loft angle in a linear manner or a distance being inversely proportional to the loft angle in a non-linear manner. 
   
   
       28 . A golf club as defined in  claim 26 , wherein the distance comprises a distance defined by the equation of ((−0.086 * θ)+3.797)≧x ≧((−0.086 * θ) + 2 . 797 ), x is units of inches and θ is units of degrees. 
   
   
       29 . A golf club as defined in  claim 26 , wherein the distance comprises a distance defined by the equation of x=(−0.086 * θ ) +3.297, x is units of inches and θ is units of degrees.
