Golf club head with strength-enhanced rear body

Abstract

A golf club head with strength-enhanced rear body comprises a front body, a rear body and at least one supporting member. The front body comprises a face and a plurality of abutting edges. The rear body comprises a crown, a ribbon and a plurality of abutting edges, with the rear body being made of a nonmetal material having a specific gravity lower than that of the front body, and the abutting edges of the rear body being corresponding to and connecting with those of the front body. The at least one supporting member being made of a light alloy is disposed along a border between the crown and the ribbon of the rear body.

         4 . The golf club head with strength-enhanced rear body as defined in  claim 1 , wherein the rear body further comprises a rear sole, with the rear body forming the crown, the ribbon and the rear sole integrally by injection molding and receiving the at least one supporting member. 
     
     
         5 . The golf club head with strength-enhanced rear body as defined in  claim 4 , wherein the rear body partially receives the at least one supporting member, with the at least one supporting member emerging from an outer surface of the rear body. 
     
     
         6 . The golf club head with strength-enhanced rear body as defined in  claim 4 , wherein the rear body partially receives the at least one supporting member, with the at least one supporting member being totally received within the rear body. 
     
     
         7 . The golf club head with strength-enhanced rear body as defined in  claim 1 , wherein the supporting member further comprises a rib extending across the crown from the ribbon to the face of the front body and being disposed within the crown of the rear body. 
     
     
         8 . The golf club head with strength-enhanced rear body as defined in  claim 1 , wherein an anodizing treatment or a surface coating treatment is applied to an outer surface of the supporting member. 
     
     
         9 . The golf club head with strength-enhanced rear body as defined in  claim 1 , wherein the front body further comprises a sidewall and a neck, with the sidewall being formed by bending a perimeter of the face and extending in a direction away from the face, with the neck being provided for connecting to a shaft. 
     
     
         10 . The golf club head with strength-enhanced rear body as defined in  claim 9 , wherein the face, the sidewall and the neck are integrally formed by casting, and the front body further comprises a front sole connecting to a sole portion of the sidewall by welding. 
     
     
         11 . The golf club head with strength-enhanced rear body as defined in  claim 10 , wherein the front body further comprises a sidewall engaging portion and a front sole engaging portion respectively extend from edges of the sidewall and the front sole to engage with the rear body. 
     
     
         12 . The golf club head with strength-enhanced rear body as defined in  claim 11 , wherein the rear body adheres to the engaging portions of the front body through an adhesive, with the adhesive being selected from a group consisting of epoxy resin, acrylic resin, polyurethane resin, neoprene rubber or elastic resin. 
     
     
         13 . The golf club head with strength-enhanced rear body as defined in  claim 10  further comprising a weight member provided on an inner surface of the front sole and away from the face of the rear body. 
     
     
         14 . The golf club head with strength-enhanced rear body as defined in  claim 1 , wherein the abutting edges of the front body comprises a sidewall abutting edge and a front sole abutting edge, and the abutting edges of the rear body comprises a crown abutting edge, a ribbon abutting edge and a rear sole abutting edge, with the crown abutting edge and the ribbon abutting edge connecting to the sidewall abutting edge and the rear sole abutting edge connecting to the front sole abutting edge. 
     
     
         15 . The golf club head with strength-enhanced rear body as defined in  claim 1 , wherein the at least one supporting member is made of aluminum alloy, magnesium alloy, or titanium alloy.
