Interchangeable club head system

Abstract

Disclosed herein are apparatuses, systems, and kits for interchangeable golf clubs having a set of shafts, each shaft having a grip and an end configured to be inserted into an adapter; a set of adapters, each adapter having an open end and a threaded end, the open end configured to receive the end of one shaft of the set of shafts; a set of weights, each weight configured to receive the threaded end of one adapter of the set of adapters; and a set of club heads, each club head having a stem and a striking surface extending from the stem, each stem configured to be reversibly coupled to one adapter of the set of adapters, and each striking surface being different for each club head, wherein assembling one shaft, one adapter, one weight, and one club head provides a golf club.

What is claimed is: 
     
         1 . An interchangeable golf club kit, comprising:
 a set of shafts;   a set of adapters, each adapter having an neck configured to receive an end of one shaft of the set of shafts, and a receiving column;   a set of weights, each weight configured to be disposed onto the receiving column of the set of adapters; and   a set of club heads, each club head having a hosel and a striking surface, and each striking surface being different for each club head, wherein a length of each shaft, a mass of each adapter, and a mass of each weight are configured to provide a golf club having a desired swing weight when assembled.   
     
     
         2 . The golf club kit of  claim 1 , wherein each shaft has a respective, different length that the other shafts in the set of shafts. 
     
     
         3 . The golf club kit of  claim 1 , wherein each adapter has a corresponding shaft of the set of shafts and a corresponding weight of the set of weights which provide the golf club having a desired swing weight when assembled. 
     
     
         4 . The golf club kit of  claim 1 , wherein, for each adapter, an outer surface of the receiving column has a fin extending radially from a central axis of the adapter. 
     
     
         5 . The golf club kit of  claim 4 , wherein the fin extends parallel with the central axis of the adapter. 
     
     
         6 . The golf club kit of  claim 4 , wherein the fin extends to a height that is less than a maximum diameter of a tapered profile along a portion of the neck. 
     
     
         7 . The golf club kit of  claim 4 , wherein, for each club head, the hosel has a recess shaped to receive the fin. 
     
     
         8 . The golf club kit of  claim 4 , wherein each adapter has at least three fins. 
     
     
         9 . The golf club kit of  claim 2 , wherein each adapter of the set of adapters has a mass which is 30 grams or less. 
     
     
         10 . The golf club kit of  claim 2 , wherein the golf club kit includes a number of shafts, adapters, weights, and club heads which corresponds to an experience level of a user. 
     
     
         11 . A golf shaft adapter, comprising:
 a neck having a first cavity configured to receive a shaft;   a receiving column configured to receive a weight;   a second cavity configured to receive a connector; and   the neck and the receiving column are arranged at opposing ends and aligned along a central axis of the adapter, wherein the adapter and the weight are configured to provide a desired swing weight when the shaft is received into the first cavity and the weight is received on the receiving column.   
     
     
         12 . The adapter of  claim 11 , wherein the adapter has a mass that is less than 30 grams. 
     
     
         13 . The adapter of  claim 11 , wherein the adapter has a tapered profile along a portion of the neck. 
     
     
         14 . The adapter of  claim 13 , wherein the adapter has a recess extending into the tapered profile which is configured to receive a notch from a hosel of a club head assembled to the adapter. 
     
     
         15 . The adapter of  claim 13 , wherein an outer surface of the receiving column has a fin extending radially from the central axis of the adapter. 
     
     
         16 . The adapter of  claim 15 , wherein the fin extends parallel with the central axis of the adapter. 
     
     
         17 . The adapter of  claim 15 , wherein the fin extends to a height that is less than a maximum diameter of the tapered profile. 
     
     
         18 . The adapter of  claim 15 , wherein the outer surface has fin extending radially from the central axis of the adapter. 
     
     
         19 . The adapter of  claim 13 , wherein an outer diameter of the receiving column is less than a maximum diameter of the tapered portion. 
     
     
         20 . The adapter of  claim 15 , wherein the adapter has a visual marker aligned with the fin.
