Golf club head
First Claim
1. A correlated set of golf club heads comprising:
- a first golf club head having a first loft angle and a second golf club head having a second loft angle that is different from the first loft angle, each of the first golf club head and the second golf club head including;
a strike face;
a perimeter-weighting element behind the strike face, the perimeter weighting element including an inner peripheral wall having at least one of a top surface, a sole surface, a heel surface, and a toe surface, the inner peripheral wall delimiting a cavity having a base surface; and
a first insert in the cavity the first insert comprising;
a primary element associated with the base surface, and at least one secondary element pivotably coupled with the primary element, by a passive flexural coupling configured to exert a negligible biasing force on the primary and secondary elements as the primary and secondary elements are pivoted relative to each other, the flexural coupling comprising a recessed region, and the at least one secondary element associated with at least one of the top surface, the sole surface, the toe surface, and the heel surface.

Abstract
At least two golf clubs of a set, according to one or more aspects of the present invention, may include a strike face and a perimeter weighting element disposed behind the strike face. The perimeter weighting element may include an inner peripheral wall having a sole surface, a top surface, a heel surface, and a toe surface. A cavity, having a base surface, may be delimited by the inner peripheral wall and may include an insert disposed therein. The insert may comprise a primary element passively flexurally associated with one or more secondary elements and may be substantially identical for each head within the set. The primary element may be associated with the base surface and the at least one secondary element may be associated with at least one of the sole surface, the top surface, the toe surface, and the heel surface.
