Abstract: An iron-type golf club head includes a striking face; a base surface opposite the striking face; and a perimeter weighting element surrounding the base surface and including a top-line portion, a sole portion, a heel portion, and a toe portion. A first auxiliary cavity is delimited by the perimeter weighting element and a first perimeter wall, the first perimeter wall coupled to the sole portion and to the heel portion of the perimeter weighting element. A second auxiliary cavity is delimited by the perimeter weighting element and a second perimeter wall, the second perimeter wall coupled to the sole portion and to the toe portion of the perimeter weighting element. A central cavity is at least partially delimited by the base surface, the perimeter weighting element, the first perimeter wall, and the second perimeter wall, and an insert is within the central cavity.

Abstract: A golf club head according to one or more aspects of the present invention may include a main cavity having at least one auxiliary cavity and a base surface. An insert may be associated with the base surface and may comprise at least two contact elements, with a bridge member disposed therebetween. Different contact elements of the insert may be disposed in separate respective auxiliary cavities, such that each contact element may be associated with the base surface. The bridge member of the insert may be dissociated from the base surface. Moreover, a surface coating may be selectively applied to the head to permit a durable adhesive bond between the insert and the base surface.
Abstract translation: 根据本发明的一个或多个方面的高尔夫球杆头可以包括具有至少一个辅助腔和基座表面的主腔。 插入件可以与基部表面相关联，并且可以包括至少两个接触元件，桥构件设置在它们之间。 插入件的不同接触元件可以设置在分开的各个辅助空腔中，使得每个接触元件可以与基座表面相关联。 插入物的桥构件可以从基底表面离解。 此外，表面涂层可以选择性地施加到头部，以允许插入件和基部表面之间的耐久粘合剂粘合。
