Golf clubs with variable moment of inertia and methods of manufacture thereof
First Claim
1. A golf club head comprising:
- a body having a front section, the front section comprising;
a first zone; and
a second zone substantially opposite the first zone;
a first restrictor mechanism comprising a first restrictor and coupled to a first portion of the body; and
a weight comprising a first end coupled to the first restrictor mechanism and coupled to the body;
wherein;
the first restrictor comprises a first stiffness and is non-integral with the weight;
in response to an impact at the first zone of the front section;
the first restrictor and the first end of the weight react towards each other; and
the first stiffness is configured to resist a deformation of the first restrictor by the first end of the weight; and
in response to an impact at the second zone of the front section;
the first restrictor and the first end of the weight react away from each other such that the first stiffness is substantially non-involved with first end of the weight.

Abstract
In some embodiments, a golf club head has a body with a front section, a first restrictor of a restrictor mechanism coupled to a first portion of the body, and a weight having a first end coupled to the restrictor mechanism and to the body. The first restrictor has a first stiffness and is non-integral with the weight. Responsive to impact at a first zone of the front section, the first restrictor and the first end of the weight react towards each other, and the first stiffness can resist a deformation of the first restrictor by the first end of the weight. Responsive to impact at a second zone of the front section, the first restrictor and the first end of the weight react away from each other such that the first stiffness is substantially non-involved with first end of the weight. Other examples and related methods are also described herein.

32. A method of manufacturing a golf club head, the method comprising:
-
providing a body; providing a weight; providing a first tab coupler coupled to a first region of the body and comprising a first tab; and coupling a first end of the weight to the first tab; wherein; a rotational tendency of the body is restricted by an interaction between the first end of the weight and the first tab upon an impact at a first portion of the body of the golf club head; the rotational tendency of the body is substantially uninhibited by the interaction between the first end of the weight and the first tab upon an impact at a second portion of the body; and the first and second portions of the body are at opposite ends of a front face of the golf club head. - View Dependent Claims (33, 34)

35. A golf club comprising:
-
a face; a housing; a golf club shaft coupled to the housing; a first restrictor coupled to a first section within the housing; a second restrictor coupled to the first section within the housing; a weight comprising a first end between the first restrictor and the second restrictor within the housing; and a third restrictor coupled to a second section within the housing and to the weight; wherein; the second restrictor comprises a second stiffness; the first restrictor comprises a first stiffness greater than the second stiffness; the first stiffness is configured to resist a distortion of the first restrictor by the first end of the weight in response to an impact at a first portion of the face of the golf club head; and the second stiffness is configured to allow a distortion of the second restrictor by the first end of the weight in response to an impact at a second portion of the face of the golf club head. - View Dependent Claims (36, 37, 38, 39)
