Interchangeable shaft and club head connection system
View Patent ↗Disclosed herein is a golf club including a shaft, a club head and several devices for releasably connecting the shaft to the club head.
1. A golf club and shaft connection system comprising:
a first hosel part, distinct from a shaft wherein the shaft partially passes through, connected to the shaft having a shaft axis,
an annular member, distinct from the first hosel part, circumferentially attaches to the first hosel part,
wherein the annular member has a top line and a bottom line, wherein the top line is not parallel to the bottom line, altering at least one of a loft angle and a lie angle of the golf club head depending on the orientation of the annular member,
wherein an entire tip end of the first hosel part cannot be removed via a bottom sole portion of a golf club head;
wherein said top line and said bottom line of said annular member both have serrated surfaces; and
wherein an external walls of the first hosel part are parallel from a first side to an opposite side from top to bottom, and wherein a central axis of the annular member aligns with the shaft axis.
2. The golf club and shaft connection system of claim 1 , wherein a first side of the annular member is opposite to a second side of the annular member.
3. The golf club and shaft connection system of claim 2 , wherein the first side of the annular member and the second side of the annular member have different lengths.
4. The golf club and shaft connection system of claim 1 , wherein the first side of the annular member having an angle α and a second side of the first hosel part having an angle β, wherein angle α is greater than angle β, and the shaft coincides with a vertical axis, wherein the shaft is shifted toward the first side of the annular member by an amount equal to |90°−β|+|90−α|.
5. The golf club and shaft connection system of claim 4 , wherein the ring is askew.
