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 an insert (30) at said thin end of said shaft (10), a primary weight (20) received in said hollow shaft (10), said primary weight (20) having two oppose recesses (21, 22) defined in ends thereof, and a secondary weight (60) received therein in a location adjacent to a end of said primary weight (20) opposed to said insert (30), said insert (30) and said secondary weight (60) each having a boss (35, 62) configured to fit in corresponding one of said recesses of said primary weight (20);

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) has a threaded inner periphery (15) defined at said thin end (13) thereof, and wherein said insert (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).

3. The golf club as claimed in claim 2, wherein an inner collar (53) is formed in said stepped hole (511) of said head (50), and wherein said threaded outer section (32) of said insert (30) extends through said inner collar (53) and is threadedly engaged with a nut (40), thereby attaching said head (50) to said shaft (10).

4. The golf club as claimed in claim 3, wherein said primary weight (20) and said insert (30) are joined to said shaft (10) by gel (70).
