MODHOSL (Modular Putter Hosel and Head Assembly with Lie Angle Adjustability)

We’ve been using this method of assembly and configuration since 2007. These interchangeable hosel adaptors allow us to custom bore your lie angle, your shaft position and handedness without altering the putter’s chassis. This flexibility also allows us tune frequency based on material selection. IE - Titanium, Stainless, Magnesium.

The present invention is a modular hosel and head assembly for golf putters designed to address the manufacturing and fitting limitations of existing putter designs. The system provides a simple yet robust mechanism for a manufacturer to install a hosel in a putter head in multiple configurations, allowing for a single putter head design to be used for both right-and left-handed players and to accommodate a wide range of lie angles.

The system achieves this by utilizing a hosel with an offset shaft connection and a head with a modular port. The hosel can be installed in at least two different positions within the head to accommodate right and left-handed players. By using different hosel designs, each with a different shaft exit angle, the system can also provide a range of lie angles from approximately 60 to 80 degrees, a range that accommodates a vast majority of golfers. This modular approach drastically simplifies manufacturing, reduces inventory, and provides a superior fitting experience.

Key Features:

Tuning Feel and Resonance:
The resonant frequency of the putter, which influences the sound and feel, is a function of the material properties of all its components. By changing the material of the modular adaptor, the overall resonant characteristics of the assembled putter are altered. For instance, a stiffer, more massive material like steel may produce a higher-frequency, "clickier" sound and a firmer feel, while a softer, less dense material like a polymer may produce a lower-frequency, muted sound and a softer feel.
