Golf club head comprising a strike face with a hardness suitable for the hardness of a golf ball

Abstract

A golf club head comprising a substantially flat strike face configured to strike a golf ball. The head has a body having a front face, at least one cavity opening on the front face, at least one ballast made of a second dense material, positioned in the at least one cavity and secured to the body, a front layer that has a first face forming the strike face and a second face opposite the first face, the second face of the front layer being in contact with the body and secured thereto, at least over the entire periphery of the front face, the front layer being made of a first material that has a Shore A hardness of less than 35.

         12 . A golf club head comprising:
 a planar striking face configured to strike a golf ball,   a body having a front face and at least one cavity opening into the front face,   at least one ballast weight which is made of a dense material and positioned in the at least one cavity and is secured to the body,   a front layer which has a first face forming the striking face and a second face opposite the first face, the second face of the front layer being in contact with the body and secured to the body, at least over an entire periphery of the front face, said front layer being made from a first material which has a Shore A hardness less than 35.   
     
     
         13 . The golf club head as claimed in  claim 12 , wherein the first material is wood with a Janka hardness greater than or equal to 1500 lbf and less than 4000 lbf. 
     
     
         14 . The golf club head as claimed in  claim 12 , wherein the front layer has a thickness of between 3 and 8 mm. 
     
     
         15 . The golf club head as claimed in  claim 12 , wherein the at least one ballast weight is spaced apart from the front layer to obtain an intermediate zone delimited by the ballast weight, the front layer, and the body. 
     
     
         16 . The golf club head as claimed in  claim 15 , wherein the intermediate zone is completely filled with at least one third material configured to dampen noise. 
     
     
         17 . The golf club head as claimed in  claim 16 , wherein the first material, the dense material, and the third material are arranged such that the first material has a hardness less than the hardness of the third material, which is less than the hardness of the dense material. 
     
     
         18 . The golf club head as claimed in  claim 12 , wherein the body comprises multiple cavities distributed on either side of a fastening system configured to connect the head to a shaft. 
     
     
         19 . The golf club head as claimed in  claim 18 , wherein the fastening system is off-center and in that the body comprises a cavity on a first side of the fastening system and multiple cavities on a second side of the fastening system. 
     
     
         20 . The golf club head as claimed in  claim 12 , wherein the body comprises multiple cavities all having a cross section that is the same in a plane parallel to the front face. 
     
     
         21 . The golf club head as claimed in  claim 12 , wherein the body comprises a filler material interposed between the ballast weight and the at least one cavity, the filler material having a density which is lower than that of the ballast weight. 
     
     
         22 . A golf club comprising:
 the head as claimed in  claim 12 .
