Golf club head including mechanical and adhesive joints
First Claim
1. A golf club head for a golf club, the golf club head comprising:
- a metallic section including a face and a frame, the face and frame defining a first opening, and the frame projecting from the face and extending continuously around the first opening;
a polymeric section extending over and covering the first opening, the polymeric section including a sole and a crown that cooperatively define a second opening;
an adhesive material disposed between the metallic section and the polymeric section forming an adhesive joint therebetween, the adhesive joint binding the polymeric section to the metallic section; and
a mechanical joint interposed between and mechanically coupling the metallic and polymeric sections, the mechanical joint including a flange protruding from one of the polymeric section or the metallic section, and a channel recessed into the other of the polymeric section or the metallic section, the channel seating therein the flange and the adhesive joint, the channel including first and second adjoining walls at least partially surrounding the flange and the adhesive joint, the flange surrounding the first and second openings, and the channel surrounding the first and second openings, the mechanical joint further including first and second projections protruding from first and second sides, respectively, of the flange, the first and second projections abutting the first and second walls, respectively, to thereby form an interference fit between the channel and the flange.

Abstract
A golf club head includes a metallic section, a polymeric section, and an adhesive material. The metallic section defines an opening and the polymeric section extends over the opening. The adhesive material is disposed between the metallic section and the polymeric section to form an adhesive joint therebetween. The adhesive joint has an adhesive retaining strength configured to inhibit the polymeric section from being detached from the metallic section when the adhesive material is at least partially cured. The metallic section and the polymeric section are also mechanically engaged with one another to form a mechanical joint therebetween having a mechanical retaining strength configured to inhibit the polymeric section from being detached from the metallic section. The adhesive retaining strength of the adhesive joint, alone, is greater than the mechanical retaining strength of the mechanical joint, alone, only when the adhesive material is at least partially cured.

9. A wood type golf club head comprising:
-
a forward section including a face and a frame, the face and frame defining a first opening, and the frame projecting from the face and extending continuously around the first opening; a body bonded to the forward section and covering the first opening, the body including a first polymeric section and a second polymeric section that cooperatively define a second opening; an adhesive material disposed between the body and the forward section and between a portion of the first polymeric section and the second polymeric section to form an adhesive joint therebetween, the adhesive joint binding the first polymeric section to the second polymeric section when the adhesive material is at least partially cured; and a mechanical joint interposed between and mechanically coupling the body, the forward section, and the first and second polymeric sections, the mechanical joint including a first flange protruding from one of the first polymeric section or the second polymeric section, a second flange protruding from one of the body or the forward section, a first channel recessed into the other of the first polymeric section or the second polymeric section, and a second channel recessed into the other of the body or the forward section, the first channel seating therein the first flange and including adjoining walls at least partially surrounding the first flange, and the second channel seating therein the second flange and including first and second adjoining walls at least partially surrounding the second projection, the second flange surrounding the first and second openings, and the second channel surrounding the first and second openings, the mechanical joint further including first and second projections protruding from first and second sides, respectively, of the second flange, the first and second projections abutting the first and second walls, respectively, of the second channel to thereby form an interference fit therebetween. - View Dependent Claims (10, 11, 12, 13)

20. A golf club head for a golf club, the golf club head comprising:
-
a metallic section with a face and a frame, the face and frame defining a first opening, and the frame projecting from the face and extending continuously around the first opening, wherein the face is integrally formed with the frame; a polymeric section extending across and covering the first opening, the polymeric section including a sole attached to a crown to cooperatively define a second opening; a mechanical joint interposed between and coupling the metallic and polymeric sections, the mechanical joint including a flange protruding from the metallic section and a channel defined by the polymeric section, the flange and channel both surrounding the first and second openings, the channel including first and second adjoining walls seating therein the flange, and the flange including first and second projections abutting the first and second walls, respectively, to close off the channel and form an interference fit between the channel and the flange; and an adhesive material disposed inside the channel and at least partially surrounding the flange, the adhesive material forming an adhesive joint between and thereby binding the metallic section and the polymeric section.
