Golf driver with selective head weighting system
Abstract
An improved golf driver head design is presented which permits
golf drivers to be adjusted to correct the swing characteristics of
most golfers. A system of attachable weights is shown which make it
possible to adjust golf club swing characteristics at the factory
simply and economically. The invention is cast from very light
weight metals to allow the maximum amount of weight adjustment
within the head while keeping the head weight to a minimum.

Description
FIELD OF THE INVENTION
[0001] This invention relates to golf drivers with adjustable swing
characteristics. These adjustable swing characteristics are
implemented with a series of weights mounted within the head.
BACKGROUND OF THE INVENTION
[0002] Golf driver heads with adjustable weighting are a new field
of invention, based on golf club heads that are made of hollow
metal shapes cast from lightweight materials. Changing the swing
plane of the golf club by adjusting the weighting of the driver
head is new as well.
[0003] The use of super-lightweight metals in the construction of
the golf driver head permits a head to be constructed that
possesses the same structural strength but substantially lower
weight than a conventional steel or wood head. There are advantages
to golf driver heads that have such low weight characteristics.
[0004] One specific advantage exploited by the present invention is
the ability to place additional weights at selected points in the
golf club head. Placing weights in this manner can affect important
characteristics of the head and the club itself
[0005] For example, other manufacturers, such as Taylor Made.TM.,
have developed golf club driver heads with adjustable weights in
the head itself. These weights are removable and can be moved as
desired by the golfer, depending on the club swing plane
characteristics he desires.
SUMMARY OF THE INVENTION
[0006] The present invention is hollow, light-weight metal driver
head inside of which are cast several attachment points for
tungsten or steel weights. This invention is a new combination of
light-weight metal casting technology for golf clubs and a new
weighting system for adjusting the swing plane of the club.
[0007] The use of light-weight metals such as magnesium or titanium
permits the club designer to cast a driver head that weighs less
than a standard driver head and allows the addition of weights
within the hollow head to adjust the effective swing plane when the
club is swung. Other manufacturers with similar weighting schemes
can place up to 12 grams of adjustment weights in the head to
change club swing path characteristics. Because of its unique
low-weight design, the present invention driver head can make use
of an additional 25 to 30 grams of adjustment weights.
[0008] Unlike the Taylor Made.TM. design, the present invention
installs the adjustment weights permanently. The cast golf club
head can be drilled out in certain pre-selected points in the
casting and adjustment weights added by screwing them in and gluing
them in place. There is a specific process used to determine the
amount of weighting and the placement of the weights needed to
correct a golfer's swing. Additional weighting can be placed in the
toe or heel of the golf club head to correct for hooking or
slicing.
[0009] The process would begin with measurement of a golfer's swing
characteristics. A measurement lab, such as Max Out Golf Labs,
would perform an analysis of a golfer's build, physical
considerations, such as chronic injuries, athletic ability, and
other parameters. The process would use ultra high speed cameras,
sensors, and accelerometers to capture the physics of a golfer's
swing. Data analysis would then be performed to accumulate factors
such as: ball velocity, launch angle, spin rates, clubhead speed,
and shaft load profiles.
[0010] Additional computer analysis and performance testing will
identify the optimum driver head weighting for the golfer to
correct detected swing deficiencies or adjust the golfer's swing to
meet his preferences. Some players like to draw the ball all the
time, or need more loft on their drives. These preferences can be
addressed with the proper weighting applied to the present
invention.
[0011] Beyond the tailored weighting of the present invention to
correct golfers' swing characteristics, the "sweet spot" of the
club head can be expanded with the application of proper weights to
the attachment points.

DETAILED DESCRIPTION OF THE INVENTION
[0021] The present invention is an improved golf driver head
design, with a metallic golf driver head 100 and and several
metallic weights 130 attached to the interior of the driver head
100. Referring to FIG. 2 and FIG. 3, the invention has several
weight attachment points 102 in the driver head lower section 104
and driver head upper section 101 which are part of the casting of
the driver head 100.
[0022] The weights 130 are manufactured in a variety of gram
weights, for example, 5, 10, and 15 grams. The weights 130 can be
made from metals such as tungsten, selected for their density and
hardness. The weights 130 have decorative heads which are flush
with the surface of the golf driver head 100 when assembled in
place at the factory. The weighting of an individual club head is
not adjustable by the end-user golfer after the club leaves the
factory.
[0023] The driver head 100 is connected to a hosel piece 127 that
is inserted into the driver head upper section 101 at hosel
insertion hole 118 and through it into the driver head lower
section 104 into a receiving recess 117 at the hosel connection
point 110. The driver head lower section 104 possesses three sole
plate attachment points 108 where the sole plate 109 is connected
to the driver head lower section 104. In the preferred embodiment,
the connection means is a set of brass screws.
[0024] In FIG. 6, the interior of the driver head upper section 101
is shown, where there are a plurality of weight attachment points
111. The same weights 130 as used for the driver head lower section
104 attachment points 102 may be attached at these attachment
points 111 to adjust driver swing plane characteristics.
[0025] The driver head lower section 104 and the driver head upper
section 101 can be attached to each other by several means,
including strong adhesives and welding of the metals. In the
preferred embodiment, these two components are glued together by
means of adhesive.
[0026] The hosel piece 102 is inserted into a hole 118 drilled
through the driver head upper section 101 and into the hosel
connection point 110, which has also been drilled with a receiving
recess 117. The preferred means of attaching the hosel piece 102 to
the driver head is a strong adhesive, although the hosel piece 102
could also be welded in place.
[0027] During manufacturing, the invention can be drilled to
receive the weights 130 in such a manner as to weight the golf club
head 100 to improve the golfer's swing plane. The underside of the
driver head lower section 104 as shown in FIG. 4 can be drilled at
a points corresponding to the weight attachment points 102 on the
interior of the lower section 104.
[0028] The holes (not shown) can be threaded to receive the weights
130, which can be screwed in and secured permanently by a weight
securing means so they will not move when the club is swung. The
best mode weight securing means is screw-threading the weights and
screw threads drilled into the holes at the weight attachment
points 102. The weights will be secured by means of adhesive so
that they are permanently placed.
[0029] Proper choice of weights 130 and locations for attachment
102,111 permits the club head assembler at the factory to correct
for slicing, hooking, low or high loft, or to expand the "sweet
spot" of the club face. The present invention provides a unique
capability to create a variety of specialized clubs with widely
varying performance characteristics by using a simple club head
weighting scheme.
[0030] While the present invention has been described above and a
preferred embodiment of the invention has been identified, changes
and substitutions of equivalent features can be made without
departing from this invention. Those skilled in the art of driver
design will recognize that many variations of this described
embodiment of the invention can be resorted to without leaving the
boundaries of this specification and associated claims below.
