Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a replaceable golf club,
and more particularly to a replaceable golf club, wherein user only
needs to carry one primary rod and thirteen secondary rods without
having to carry thirteen golf clubs, thereby facilitating the user
carrying the golf club, and thereby reducing the weight of the golf
club.
[0003] 2. Description of the Related Art
[0004] The closest prior art of which the applicant is aware is
disclosed in Taiwanese Patent Publication No. 371901, entitled by
"Golf Club Connector", which disclosed a golf club including two
stages that are connected by a shock absorbing connector. However,
the user has to carry many golf clubs (the whole golf set includes
thirteen golf clubs), thereby causing inconvenience to the user
when carrying the many golf clubs.
SUMMARY OF THE INVENTION
[0005] The present invention has arisen to mitigate and/or obviate
the disadvantage of the conventional golf club.
[0006] The primary objective of the present invention is to provide
a replaceable golf club, wherein user only needs to carry one
primary rod and thirteen secondary rods without having to carry
thirteen golf clubs, thereby facilitating the user carrying the
golf club, and thereby reducing the weight of the golf club.
[0007] In accordance with the present invention, there is provided
a replaceable golf club, comprising: a primary rod combined with a
secondary rod, wherein:
[0008] an upper insertion tube is inserted into a distal end of the
primary rod, the upper insertion tube includes an upper shock
absorbing portion rested on and flush with the distal end of the
primary rod; and
[0009] a lower insertion tube is inserted into a distal end of the
secondary rod, the lower insertion tube includes a lower shock
absorbing portion rested on and flush with the distal end of the
secondary rod, and the lower shock absorbing portion is secured
with the upper shock absorbing portion.
[0010] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0016] Referring to the drawings and initially to FIGS. 1-3, a
replaceable golf club in accordance with a preferred embodiment of
the present invention comprises a primary rod 30 combined with a
secondary rod 40, which are made of carbon fiber. The primary rod
30 is formed with an insertion hole 31, and the secondary rod 40 is
formed with an insertion hole 41.
[0017] An upper insertion tube 10 made of metallic material is
inserted into the insertion hole 31 of the primary rod 30, and a
lower insertion tube 20 made of metallic material is inserted into
the insertion hole 41 of the primary rod 40. The upper insertion
tube 10 is fitted with the lower insertion tube 20, so that the
primary rod 30 may be combined with the secondary rod 40 to form a
golf club as shown in FIG. 3.
[0018] The upper insertion tube 10 is a hollow tube, and includes
an insertion portion 11 inserted into and secured in the insertion
hole 31 of the primary rod 30 by adhesive glue. The upper insertion
tube 10 includes an upper shock absorbing portion 12 formed on one
end of the insertion portion 11 and having an outer diameter
greater than that of the insertion portion 11. The upper shock
absorbing portion 12 may be rested on and flush with a distal end
of the primary rod 30.
[0019] The upper insertion tube 10 has an inner wall having a first
portion formed with a screw hole 13, and a second portion formed
with a guide groove 14 having an inner diameter greater than that
of the screw hole 13.
[0020] The lower insertion tube 20 is also a hollow tube, and
includes an insertion portion 21 inserted into and secured in the
insertion hole 41 of the secondary rod 40 by adhesive glue. The
lower insertion tube 20 includes a lower shock absorbing portion 22
formed on one end of the insertion portion 21 and having an outer
diameter greater than that of the insertion portion 21. The lower
shock absorbing portion 22 may be rested on and flush with a distal
end of the secondary rod 40.
[0021] The lower insertion tube 20 includes a shaft portion 23
formed on and protruded from the lower shock absorbing portion 22.
The shaft portion 23 of the lower insertion tube 20 may be inserted
into the guide groove 14 of the upper insertion tube 10, and has a
distal end formed with a screw portion 24 that may be screwed into
the screw hole 13 of the upper insertion tube 10.
[0022] In assembly, the insertion portion 11 of the upper insertion
tube 10 is initially inserted into and secured in the insertion
hole 31 of the primary rod 30 with the upper shock absorbing
portion 12 being rested on and flush with the distal end of the
primary rod 30, and the insertion portion 21 of the lower insertion
tube 20 is inserted into and secured in the insertion hole 41 of
the secondary rod 40 with the lower shock absorbing portion 22
being rested on and flush with the distal end of the secondary rod
40 as shown in FIG. 1.
[0023] The shaft portion 23 of the lower insertion tube 20 is then
inserted into the guide groove 14 of the upper insertion tube 10,
and the screw portion 24 is then screwed into the screw hole 13 of
the upper insertion tube 10, until the upper shock absorbing
portion 12 is rested on the lower shock absorbing portion 22, so
that the primary rod 30 may be combined with the secondary rod 40
to form a golf club as shown in FIG. 3.
[0024] Referring to FIGS. 4 and 5, the primary rod 30 may be mated
with a secondary rod 40 and a striking head 50 to form a golf club
as shown in FIG. 4, and may be mated with a secondary rod 400 and a
striking head 500 to form another golf club as shown in FIG. 5.
Thus, the primary rod 30 may be mated with different kinds of
secondary rods 40 (usually thirteen secondary rods 40), so that the
user only needs to carry one primary rod and thirteen secondary
rods without having to carry thirteen golf clubs, thereby
facilitating the user carrying the golf club.
[0025] The upper shock absorbing portion 12 of the upper insertion
tube 10 is formed with a detachment hole 120, and the lower shock
absorbing portion 22 of the lower insertion tube 20 is formed with
a detachment hole 220, so that the user may use two hook-shaped
wrenches to lock the detachment hole 120 of the upper shock
absorbing portion 12 and the detachment hole 220 of the lower shock
absorbing portion 22, and to rotate the upper insertion tube 10 and
the lower insertion tube 20 toward opposite directions, thereby
detaching the primary rod 30 from the secondary rod 40.
[0026] In conclusion, the replaceable golf club in accordance with
the present invention has the following advantages.
[0027] 1. The upper shock absorbing portion 12 and the lower shock
absorbing portion 22 are mounted between the upper insertion tube
10 and the lower insertion tube 20, thereby achieving a shock
absorbing effect.
[0028] 2. The user only needs to carry one primary rod and thirteen
secondary rods without having to carry thirteen golf clubs, thereby
facilitating the user carrying the golf club, and thereby reducing
the weight of the golf club.
[0029] 3. The screwing direction of the screw portion 24 of the
lower insertion tube 20 and the screw hole 13 of the upper
insertion tube 10 is different from the direction of the striking
force of the golf club, so that the primary rod 30 may be combined
with the secondary rod 40 stably and rigidly.
[0030] 4. The upper shock absorbing portion 12 of the upper
insertion tube 10 is formed with a detachment hole 120, and the
lower shock absorbing portion 22 of the lower insertion tube 20 is
formed with a detachment hole 220, thereby facilitating the user
detaching the primary rod 30 from the secondary rod 40.
[0031] Although the invention has been explained in relation to its
preferred embodiment as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
