Golf club head

Abstract

A golf-club head has a shaped crown integrally including skirt and a hosel connection having a hosel attachment opening. A bottom plate is welded to the crown and allows solder leakage concentrating on the lower part of the head. A striking face is welded to the crown. A hosel is welded to the crown at the hosel connection.

1 . A golf-club head comprising: 
 a. a crown integrally including skirt and a hosel connection having a hosel attachment opening;    b. a bottom sole welded to the crown, wherein solder leakage concentrates on the lower part of the head;    c. a striking face welded to the crown; and    d. a hosel welded to the crown at the hosel connection.    
   
   
       2 . The golf-club head of  claim 1  wherein the hosel attachment opening is round and receives a standard cylindrical hosel.  
   
   
       3 . The golf-club head of  claim 1  wherein the crown and skirt are integrally formed to include an arch at the hosel connection.  
   
   
       4 . The golf-club head of  claim 1  wherein the thickness of the bottom sole is greater than the skirt plate thickness.  
   
   
       5 . The golf-club head of  claim 1  wherein the hosel attachment area of the crown terminates in a circumference matching the outside circumference of the protruding ring.  
   
   
       6 . A golf-club head comprising: 
 a. a crown formed from a single sheet of metal to integrally include a skirt and an stretched hosel connection having a hosel attachment opening;    b. a bottom sole welded to the crown, wherein solder leakage concentrates on the lower part of the head; and    c. a hosel and striking face formed from a single piece of metal and welded to the crown at the hosel connection and along an interface formed between the striking face and crown.    
   
   
       7 . The golf-club head of  claim 6  wherein the hosel attachment opening is round and receives a standard cylindrical hosel.  
   
   
       8 . The golf-club head of  claim 6  wherein the crown and skirt are integrally formed to include an arch at the hosel connection.  
   
   
       9 . The golf-club head of  claim 6  wherein the thickness of the bottom sole is greater than the skirt plate thickness.  
   
   
       10 . The golf-club head of  claim 6  wherein the hosel attachment area of the crown terminates in a circumference matching the outside circumference of the protruding ring.  
   
   
       11 . A golf-club head comprising: 
 a. a crown formed from a flat sheet of metal so that it integrally includes a skirt and a hosel connection;    b. a bottom sole welded to the crown, wherein solder leakage concentrates on the lower part of the head;    c. a striking face welded to the crown; and    d. a hosel welded to the crown at the hosel connection.    
   
   
       12 . The golf-club head of  claim 11  wherein the hosel attachment opening is round and receives a standard cylindrical hosel.  
   
   
       13 . The golf-club head of  claim 11  wherein the crown and skirt are integrally formed to include an arch at the hosel connection.  
   
   
       14 . The golf-club head of  claim 11  wherein the thickness of the bottom sole is greater than the skirt plate thickness.  
   
   
       15 . The golf-club head of  claim 11  wherein the hosel attachment area of the crown terminates in a circumference matching the outside circumference of the protruding ring.
