Abstract

A golf club with high accuracy in driving a golf ball is disclosed. The golf club includes a tapered hollow shaft having a thin end and a thick end, with a weight received in the hollow shaft. A head is formed with a neck that defines a stepped hole for fixedly receiving the thin end of the shaft. Importantly, the head is made less heavy than a related standard by an amount equivalent to the weight in the hollow shaft, and so the golf club has the same gross weight as a normal club.

Claims

1. A golf club with high accuracy in driving a golf ball, comprising:

a tapered hollow shaft (10) having a thin end (13) and a thick end, said hollow shaft (10) being formed with a weight (20) received therein;

a head (50) having a neck (51) formed thereon, said neck (51) defining a stepped hole (511) for fixedly receiving said thin end (13) of said shaft (10).

2. The golf club as claimed in claim 1, wherein said shaft (10) is formed with a hosel (30) at said thin end (13) thereof.

3. The golf club as claimed in claim 2, wherein said shaft (10) has a threaded inner periphery (15) defined at said thin end (13) thereof, and wherein said hosel (30) has a threaded outer section (32), a threaded intermediate section (33) and an annular stop (31) formed between said threaded sections (32, 33), with said threaded intermediate section (33) adapted to be threadedly engaged with said inner periphery (15) of said shaft (10) and with said annular stop (31) adapted to abut said thin end (13) of said shaft (10).

4. The golf club as claimed in claim 3, wherein an inner collar (52) is formed in said stepped hole (511) of said head (50), and wherein said threaded outer section (32) of said hosel (30) extends through said inner collar (52) and is threadedly engaged with a nut (40), thereby attaching said head (50) to said shaft (10).

5. The golf club as claimed in claim 4, wherein said weight (20) and said hosel (30) are joined to said shaft (10) by gel (70).

6. The golf club as claimed in claim 5, wherein said hollow shaft (10) is further formed with a secondary weight (60) received therein in a location adjacent to an end of said weight (20) opposed to said hosel (30).

7. The golf club as claimed in claim 6, wherein said weight (20) has two opposed recesses (21, 22) defined in ends thereof, and wherein each of said hosel (30) and said secondary weight (60) has a boss (35, 62) configured to fit in corresponding one of said recesses (21, 22) of said weight (20).
