Golf Club Head Or Other Ball Striking Device With Interchangeable Body Member

A ball striking device comprising:

• a ball striking head comprising:
• a face having a striking surface configured for striking a ball;
• a body connected to the face and extending rearward from the face;
• a hosel having a proximal end connected to the body and a distal end extending away from the body;
• and
• a connection member connected to the distal end of the hosel, wherein the face, the body, the hosel, and the connection member are formed of a polymer material;
• a shaft removably connected to the connection member of the ball striking head;
• and
• an adhesive material bonding the shaft to the connection member of the ball striking head, wherein the adhesive material has a glass transition temperature that is lower than a glass transition temperature of the polymer material of the connection member, and wherein the shaft is configured to be connected to and disconnected from the connection member by heating the adhesive material to a temperature between the glass transition temperature of the adhesive material and the glass transition temperature of the polymer material to permit the adhesive material to be bonded or debonded without damage to the shaft or the connection member.

A ball striking device comprising:

• a ball striking head comprising:
• a face having a striking surface configured for striking a ball;
• a body connected to the face and extending rearward from the face;
• and
• a hosel having a proximal end connected to the body and a distal end extending away from the body, wherein the face, the body, and the hosel are integrally formed of a single piece of a polymer material;
• and
• a shaft removably connected to the hosel of the ball striking head.

A method comprising:

• providing a ball striking head comprising:
• a face having a striking surface configured for striking a ball;
• a body connected to the face and extending rearward from the face;
• a hosel having a proximal end connected to the body and a distal end extending away from the body;
• and
• a connection member connected to the distal end of the hosel, wherein at least a portion of the head is formed of a polymer material;
• placing an adhesive material in communication with a surface of the connection member of the ball striking head, wherein the adhesive material has a glass transition temperature that is lower than a glass transition temperature of the polymer material of the head;
• heating the adhesive material to a temperature between the glass transition temperature of the adhesive material and the glass transition temperature of the polymer material;
• connecting a shaft to the connection member of the ball striking head by placing a portion of the shaft in communication with the adhesive material;
• and
• cooling the adhesive material after connecting the shaft to the connection member, such that the adhesive material bonds the shaft to the connection member of the ball striking head.
