Integral sole face club head

Abstract

A golf-club head has a first half of shaped crown integrally including skirt and a hosel connection having a hosel attachment opening. A second half is a bottom plate having an integral striking face with built-in angle of loft so that the two halves are welded together providing solder leakage concentrating on the lower part of the head. 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 having an integral striking face extending from said bottom sole, said bottom sole and striking face being welded to said crown and skirt along a closed loop of seam line, wherein solder leakage concentrates on the lower part of said head; and    c. a hosel having a lower section for inserting into said hosel attachment opening and an enlarged section with an annular transition, which is formed between said lower section and seated on said hosel connection for welding attachment thereto.    
   
   
       2 . The golf-club head of  claim 1  wherein said hosel attachment opening is round and receives a standard cylindrical hosel.  
   
   
       3 . The golf-club head of  claim 1  wherein said crown and skirt are integrally formed to include an arch at said hosel connection.  
   
   
       4 . The golf-club head of  claim 1  wherein the thickness of said bottom sole is greater than the skirt plate thickness.  
   
   
       5 . The golf-club head of  claim 1  wherein said crown and skirt are integrally formed to include an arch at said hosel connection, which terminates in a circumference matching the outside circumference of said annular transition of said hosel.  
   
   
       6 . A golf-club head comprising: 
 a. a crown formed from a single sheet of metal to integrally include a skirt and a stretched hosel connection having a hosel attachment area (opening);    b. a bottom sole having an integral striking face extending from said bottom sole, wherein solder leakage concentrates on the lower part of said head; and    c. a hosel formed integral to said striking face and sole unit for receiving a shaft, said hosel having a lower section and an enlarged section with an annular transition, which is formed between said lower section and seated on said hosel connection for welding attachment thereto, whereby said crown and skirt unit is welded to said bottom sole and striking face unit along an interface formed therebetween.    
   
   
       7 . The golf-club head of  claim 6  wherein said hosel attachment opening is round and receives a standard cylindrical hosel.  
   
   
       8 . The golf-club head of  claim 6  wherein said crown and skirt unit is integrally formed to include an arch at said hosel connection.  
   
   
       9 . The golf-club head of  claim 6  wherein the thickness of said bottom sole is greater than said skirt plate thickness.  
   
   
       10 . The golf-club head of  claim 6  wherein said crown and skirt unit includes an arch at said hosel connection, which terminates in a circumference matching the outside circumference of said annular transition of said hosel.  
   
   
       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 having an integral striking face extending from said bottom sole and being welded to said crown, wherein solder leakage concentrates on the lower part of the head; and    c. a hosel welded to said crown at said 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 said crown and skirt are integrally formed to include an arch at said hosel connection, which terminates in a circumference matching the outside circumference of said annular transition of said hosel.
