Interchangeable shaft and club head connection system

摘要

A releasable connection system for assembling a shaft and a club head, e.g., a golf club shaft and a golf club head. The connection system provides interchangeability between a shaft and a club head and allows the head to be adjusted with respect to the shaft. The mating structures between the shaft and the club head may be indexed for reproducible placement. In an embodiment, the connection system also includes retaining structures that maintain the connection fastener position when the head and shaft are separated.

主权项

1. A system for reversibly joining a club shaft to a club head, comprising:
a fastener comprising a proximal end defining a head, a distal end defining a threaded portion, and a retaining shoulder positioned along a length of the fastener between and separate from the head and the threaded portion; a club head comprising a first opening, a second opening, and a retaining member positioned within an interior of the club head and axially aligned with the first opening, wherein the first opening and the retaining member are each configured to receive at least the distal end and the retaining shoulder of the fastener entirely therethrough, wherein the retaining member is configured to span a length of the fastener between the head and the retaining shoulder and to be in contact with the retaining shoulder to prevent movement of the fastener in a direction towards the first opening, wherein the retaining member is configured to retain the fastener within the interior of the club head and in axial alignment with the second opening of the club head; and a club shaft configured to be received through the second opening of the club head and reversibly receive at least the distal end of the fastener, thereby joining the shaft and the club head.
