US Patent 7481716 Golf club grip for accommodating selectable weight assembly

A golf club grip of conventional appearance and resilient material is configured internally at its upper end with a specialized hole for accommodating a counter-weight assembly, extending into the upper end of the shaft, that is user-selectable from various available weights, which may be added to the counter-weight assembly and secured in place by a machine screw, which tightened in place, compresses a compliant bushing expanding it radially against the inner wall of the shaft, locking the grip and counter-weight assembly to the shaft to act as a single unit. This configuration of counter-weight assembly known as “TOUR LOCK Technology” provides the ability to easily interchange counter-weight assemblies of different mass.
