61/936,579 filed on Feb. 6, 2014, the contents of which are
incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] This invention relates generally to sporting good
apparatuses, more particularly to sport shafts and shaft grips with
interchangeable characteristics in order to allot the user various
strategic choices during purchase, testing, evaluation, practice,
and game play.
[0004] 2. Description of the Related Art
[0005] On present day sports equipment, such as tennis rackets,
field hockey sticks, lacrosse sticks, racket ball rackets, squash
rackets, hockey sticks, and the like, and in particular golf clubs,
the grip of the club is attached to the opposite end of the shaft
from head of the club, and is the part of the club the player holds
on to while swinging. Originally, grips were composed of one or
more leather strips wrapped around the shaft. The leather outer
wrap on a grip is still seen on some clubs, but most modern grips
are a one-piece "sleeve" made of rubber, or some other synthetic or
composite material, which is slid over the shaft and secured with
an adhesive. In the case of golf clubs, these sleeve grips allow
club makers and golfers to customize the grip's diameter,
consistency (softness/firmness) and texturing pattern to best fit
the player. Clubs with an outer "wrap" of leather or leather-like
synthetic still typically have a "sleeve" form underneath to add
diameter to the grip and give it its basic profile.
[0006] Advances in materials have resulted in more durable,
longer-lasting soft grips, but nevertheless grips do eventually dry
out, harden, get worn, or are otherwise damaged and must be
replaced. Replacement grips sold as do-it-yourself kits are
generally inexpensive and of high quality, although custom grips
that are larger, softer, or textured differently from the everyday
"wrap"-style grip are generally bought and installed by a
professional.
[0007] Re-gripping often requires toxic, flammable solvents to
soften and activate the adhesive, and a vise to hold the club
steady while the grip is forced on. However, the newest replacement
kits use double-sided tape with a water-activated adhesive that is
slippery when first activated, allowing for easier installation.
Once the adhesive cures, it creates a very strong bond between grip
and shaft and the grip is usually impossible to remove without
cutting it off.
[0008] Presently, many golf grips are secured to a golf club shaft
by use of double sided adhesive tape. Tape is applied to a golf
club shaft. Acetone is poured over the adhesive tape to eliminate
the adhesive nature on a short term basis. The grip is pressed over
the end of a shaft with the adhesive tape and slid into position.
The adhesive tape becomes adhesive very quickly making grip
placement difficult. Movement of the grip is difficult as the
adhesive tape grabs the grip making proper alignment difficult. The
end of a shaft is reverse tapered so the shaft end is much larger
than a grip opening, also making placement difficult.
[0009] Additionally, as mentioned above, in current systems,
removal and replacement of a grip normally takes a great amount of
time and labor as the grip must be cut off and the adhesive must
also be removed. Therefore, as this involves a tedious, labor
intensive and time consuming process, it is virtually impossible
for users to test different grips on clubs to ascertain which feel
suits the user. It would be advantageous to be able to try on
different grips to determine which is preferable to a golfer.
[0010] In order to re-grip a tennis, racket ball, squash, or like
rackets one must unwrap the leather or rubber grips, remove the
adhesive, apply new adhesive, and then rewrap. It is a long process
and not easily changed. It is difficult and almost impossible to
try different diameter, length or other size characteristics as the
base is a defined diameter and the wrap is limited in its
thickness.
[0011] Presently, golf clubs, tennis and other sports rackets, are
sold with a grip, shaft, and club head predetermined by golf club
manufacturers. If a golfer prefers a different type of grip, either
based on material, size, shape, color, or other characteristic, be
it structural or aesthetic, the golfer must have the component
changed after the purchase is completed. The sportsman does not
have the opportunity to try many different variations without great
difficulty. Currently, placement and replacement of golf grips on
golf club shafts is extremely tedious as there is difficulty in
both removing and installing the grips. The present, time
consuming, process does not allow for changing a grip at the time
of purchase.
[0012] Presently, golf grips are placed on a shaft by placing
double adhesive tape onto the shaft, covering the length of the
grip. The inner layer of the adhesive tape provides a secure
interface to the shaft, while the outer layer of adhesive tape
provides a secure interface to the inside of the grip.
Unfortunately, it is difficult to slide the grip over the adhesive
surface of the tape and solutions, such as acetone, are poured over
the adhesive tape and into the grip to produce a slippery surface,
which allows the grip to slide down the shaft. However if the
solvent evaporates too quickly, which happens often, the grip gets
stuck half way.
[0013] Golf club heads are normally screwed onto shafts in such a
manner as to change their position by creating a different loft,
opening or closing the face angle. Normally, club heads are tried
on to fit a person's height and swing such that the sole of a head
is striking the ground in the middle. When it is determined which
club head is appropriate, the information is sent to a manufacturer
to have the club custom manufactured.
[0014] Presently, systems have been patented to offer alternative
techniques to replace worn grips without the use of adhesives.
Primarily, screw or threaded components are used; however, they are
never designed such that a company offers various grip choices at
time of purchase. In addition, the cost of manufacturing is too
high to make it realistic to offer choices.
[0015] The present invention offers a sportsman a choice of the
appropriate grip by allowing them to try different grips varying by
size, shape, surface, feel, materials, aesthetics, and the like
regardless of the technique to join the grip to the shaft. The
method of joining must be done in a quick efficient manner so that
many grips may be tried in a short time. When a sportsman makes a
decision to purchase a grip, the grip may be fixed permanently or
left as reversible to be changed later if the wrong choice was
made.
[0016] It would also be advantageous to offer as an alternative,
but not required, option of have sliding components that lengthen
or shorten the shaft. A grip with a hollow core is constructed such
that it could slide up and down a shaft and be fixed reversibly at
any point or fixed points. The grip is secured by increasing
adhesion, friction, mechanical lock, double path of insertion,
Velcro, screw or posts, clamping, or the like.
[0017] Present systems to change club length require re-shafting or
cutting an existing shaft with re-gripping or purchasing a new
club.
SUMMARY OF THE INVENTION
[0018] The instant apparatus and system, as illustrated herein, is
clearly not anticipated, rendered obvious, or even present in any
of the prior art mechanisms, either alone or in any combination
thereof. A versatile system, method and series of apparatuses for
creating and utilizing a sports grip and interchangeable sport
grips grip for sports equipment, which are changed in a quick
efficient manner are presented to understand the concept of quick
change at the point of purchase. Point of purchase qualifies as any
location wherein people normally purchase clubs and accessories,
including sporting goods stores, Golf Stores, Golf Course Pro Shops
and Online retailers.
[0019] Thus, a sportsman is herein quickly able to able to test the
suitability of different grips with a specific club and purchase
the desired configuration on the spot. The techniques reviewed
offer a sportsman the ability to select the best grip for optimum
performance. Thus, the several embodiments of the instant apparatus
are illustrated herein.
[0020] The present invention provides a concept to secure or place
a sports club grip to a club shaft in a quick manner and removal
without the use of present adhesive tape or adhesives systems.
Controlled adhesion, reversible adhesion, friction, mechanical
lock, threaded components, screw lock, screw retention, snap,
Velcro, tape, interlocking components, differential adhesive tape,
and other common reversible techniques allowing quick removal are
used. In an alternative technique, a grip is constructed with
internal structures that snap, engage, thread, slide, or lock into
structures on a shaft or components attached to a shaft. The grip
is solid elastic material or is adhered to a plastic, metal, or
other material internal component. The internal components may be
one piece or constructed of several components. The shaft is
tapered, parallel, or reverse tapered at the grip end. A parallel
end is the preferred shape especially when sliding a grip up and
down a shaft to increase or decrease club length is desired. The
shaft has areas shaped to accept components on the grip that create
resistance to grip removal or it uses components that insert into
the shaft or grip that is friction fit such that the amount of
friction is controlled for removal or fixing into place.
[0021] In one embodiment, a grip to shaft interface is designed to
resist forces applied naturally and use the direction of no applied
force as a path for snapping and securing components together. For
example, a set of forces acting onto a golf club are generated
while striking a golf ball. The swinging motion generated around a
person's body creates centripetal forces, which could cause
dislodgement of a shaft from a grip if proper resistance is not
provided. Striking a ball with the club head creates rotational
forces in one direction. Striking the ground forces a shaft into a
grip. Components of the new invention, in several versions, utilize
the fact that little to no force is applied in the opposite
rotation created by ball striking.
[0022] Twisting of a shaft in a grip while striking a ball is
resisted by components constructed on a shaft and within a grip.
Twisting in the opposite direction is resisted by snap components,
which compress, or bend, and release into, or passed, indentations
or other components. Enough force is easily generated by hand
twisting to disengage snap locks; however, the force is more than
is generated by using a club during a round of golf. In addition,
forces of hands on a grip secure it further to a shaft, as
components that need to expand for release are compressed. For the
snap adaptation, there exist at least three known main types of
snap fits: annular, cantilever, and torsional.
[0023] In an exemplary embodiment, components in a golf club grip
will compress, and thus the diameter of the grip will expand as the
downward force of the grip placement occurs. As the compression of
components, or grip diameter expansion, is released the shaft
components are engaged. A grip is held in position by these
components. As illustrated herein, there may be as few as one
component and as many as thousands depending on their size.
[0024] Depending upon the amount of usage, golf club grips
regularly require removal and replacement. It is convenient if
grips are interchangeable so that one is able to try different
grips on golf clubs in order to see which grip is the most
effective for a particular golfer. In one embodiment of the instant
apparatus, grip removal can be predetermined to be difficult to
avoid accidental separation during use. In yet another embodiment,
removal and replacement may be rendered effortless in order to
allow a golfer to test different grips and see which grip feels
best.
[0025] For example, a grip is snapped onto a shaft and tested by a
golfer at a driving range. There is concern as a grip is used and
internal wear occurs, a grip may unsnap and release a shaft
potentially causing someone bodily harm. To avoid this, a lock
component, such as a screw going through the grip and into a shaft,
is engaged once a grip is selected. The snap components allow of
quick change and easy testing while lock components provide safety
during use. In addition, it is against USGA regulations to play
with clubs which allow alteration during play. Lock mechanisms
provide safety and adherence to the rules of golf.
[0026] An exemplary example of the benefit of quick change for
testing at the point of purchase is the ability to readily change
grips for putter use, as this feature would lend golfers the
ability to test a thicker or thinner, longer or shorter, softer or
firmer, tapered or parallel, of various colors, sticky or slick,
oval or round or flat, and all present variations of present grips.
A putter grip can be constructed to slide up and down a shaft to
make a putter shorter or longer offering a golfer the ability to
trying different length putter without changing the putter.
Presently, a golfer must alter a putter shaft to try different
lengths unless multiple putters of the same design are present at a
point of purchase with different lengths. If a shaft is cut down to
try a shorter length it is an arduous process of removing a grip,
cutting a shaft and regripping. If a golfer decides it is too
short, it may be impossible to lengthen the shaft again.
[0027] Additionally, although the herein embodiments of gripping
mechanisms have been highlighted, the instant system and all
embodiment thereof may be readily adapted for attachment of a club
head to a shaft in an identical way. This will be very important
when golfers would like to try different combinations grips,
shafts, and club heads.
[0028] It is an object of the present system to introduce the
concept of quick change at point of purchase regardless of the
method used. Currently, the choices at point of purchase and after
purchase are limited by the complexity to change components in a
quick, efficient manner that allow for use immediately after
change. With the present invention, there would be an almost
limitless amount of various choices offered at point of purchase
based on shape, size, material, texture, color, and other common
grips characteristics, which cannot be offered without great
difficulty with present systems. The quick change of grips at the
point of purchase allows a sportsman the ability to try and select
the best grip for them is different from the previous systems
intended to make change easier. There are systems previously
patented which allow for easier grip changing, however, most are
very expensive to manufacture, unrealistic to use at point of
purchase, and have not been proposed or actually been done at point
of purchase.
[0029] There are many techniques for quick exchange of grips and
club heads that can be applied in order for a customer in a store
to assess different grips, shafts, and club heads to determine
which combination best suits the customer at the time of purchase.
The customer will more likely buy a club if the feel is better
based on the grip, shaft control and head performance. Determining
which combination is better achieved by trying different
components. In addition, if a customer determines that they do not
like the grip, shaft, or club head after the purchase of the golf
clubs, they have the opportunity to easily return and exchange any
of them with another.
[0030] It is also an object of the present system to reveal and
review, as seen in previous patents by the inventor, a series of
easy exchange techniques to be utilized as grips, shafts, or club
heads wear, allowing for easy replacement of old worn grips with
new ones, particularly as grips wear out several times a year for
many golfers. Presently, the replacement of old worn grips is
accomplished by a professional club manufacturer or by the
sportsman himself. If a golfer attempts to perform the replacement,
the cost is reduced as the cost of profession labor is thus
eliminated.
[0031] It is a primary object of the present system to introduce
the concept of interchangeable components, especially grips, that
results in ease of placement and potential cost savings, which will
inherently result in greater profits for golf companies and
courses, as well as providing a better brand of golf club for the
user as the ability to have fresh grips and heads, without having
to wait for a professional to perform replacement, will enable
players to always possess their A-game as determined at point of
purchase and after purchase.
[0032] It is an object of the present system to reveal techniques
which allow exchangeable and interchangeable grips, shafts, and
club heads can include snap, screw, Velcro, interlocking, channels,
Morses taper, friction or like methods of joining and disconnection
parts quickly. The concept is not limited to just these techniques,
however, the techniques are used illustrate a methodology of
use.
[0033] It is a further object of the instant system to introduce
and review systems which allow a company to design components in
such a manner that only their replacement components can be used.
Presently, tens of millions of dollars are lost by companies as
replacement grips are manufactured and sold by other companies. The
replacement companies make tens of millions of dollars supplying
replacement grips. Internal components in a grip or grip insert are
designed to match design features, inserts, or an altered shaft
such that only these grips will fit for replacement. A golfer will
need to buy replacement grips from the original manufacturer,
dramatically increasing their profits.
[0034] It is a further object of the instant system to introduce
and review a first manner or method in which components may be
constructed to facilitate quick exchange wherein a shaft may be
composed of uniform construction such that each end facilitates the
technique of removal. It is a further object of the instant system
to introduce a manner or method in which components may be
constructed to facilitate quick exchange wherein a shaft is
constructed and altered after construction such as placing holes,
grooves, threads, taper, slots, projections or the like.
[0035] It is a further object of the instant system to introduce
and review a manner or method in which components may be
constructed to facilitate quick exchange wherein an existing shaft
is cut and inserts into the shaft are placed, or inserts are placed
into or onto a shaft without cutting. In one embodiment, a shaft
may comprise a groove, slot, dimple or like placed into a shaft
during manufacture or is altered after manufacture to provide the
desired result. In an additional embodiment, a shaft may be cut and
an insert fitted and glued with materials, such as epoxy, which are
used to hold club heads to shafts.
[0036] It is a further object of the instant system to introduce
and review a method of controlling friction or adhesion for quick
change.
[0037] It is an object of the instant system to introduce and
review utilization of compression mechanisms, adhesion control and
friction fit mechanisms, including the employment of high
coefficient of friction retention, in order or to realize
interchangeable sports grips to be utilized on numerous platforms
including sports clubs, sticks, shafts, and bats.
[0038] It is an object of the instant system to introduce a system
which employs compression, friction fit, or friction force fit
principles, with or without the presence of additional mechanisms
such as snaps, cavities, indentations or any other retaining
apparatuses, in order to restrain, and release, sports clubs,
sticks, shafts and bats. Thus, it is an object of the instant
system to introduce a system which requires no alteration to
existing sports clubs, sticks, shafts, and bats, whatsoever, due to
the inherent properties of compression and friction restraint.
[0039] It is an additional object of the instant system to
introduce a system which employs compression, friction fit, or
friction force principles, in conjunction with additional
mechanisms such as snaps, cavities, indentations, or any other
retaining apparatuses, in any combination available, in order to
restrain and release sports clubs, sticks, shafts, bats, and like
sports instruments.
[0040] The instant system provides several methods to secure a golf
club grip to a golf club shaft without the use of present adhesive
tape and adhesive systems. A grip is constructed with internal
structures that snap or lock into structures on a shaft or
components attached to a shaft. The grip may include solid elastic
material or may be adhered to a plastic, metal, or other material
internal component. The internal components may be one piece or
constructed of several components. The shaft is tapered, parallel
or reverse tapered at the grip end. A parallel is the preferred
shape. The shaft has may have areas shaped to accept components on
the grip that create resistance to grip removal.
[0041] As a means of explanation, a set of forces acting onto a
golf club are generated while striking a golf ball. The swinging
motion generated around a person's body creates centripetal forces,
which could cause dislodgement of a shaft from a grip if proper
resistance is not provided. Striking a ball with the club head
creates rotational forces in one direction. In several versions of
the invention components utilize the fact that little to no force
is applied in the opposite rotation created by ball striking.
[0042] Twisting of a shaft in a grip while striking a ball is
resisted by components constructed on a shaft and within a grip.
Twisting in the opposite direction is resisted by snap components,
which compress, or bend, and release into, or passed, indentations
or other components. Enough force is easily generated by hand
twisting to disengage snap locks, however, the force is more than
is generated by using a club during a round of golf. In addition,
forces of hands on a grip secure it further to a shaft as
components that need to expand for release are compressed. For the
snap adaptation, there exist at least three known main types of
snap fits: annular, cantilever, and torsional.
[0043] In an exemplary embodiment, components in a golf club grip
will compress, and thus the diameter of the grip will expand as the
downward force of the grip placement occurs. Compression of the
components or grip diameter expansion is released and engagement of
shaft components is engaged. A grip is held in position by these
components. As illustrated herein, there may be as few as one
component and as many as thousands depending on their size.
[0044] Depending upon the amount of usage, golf club grips
regularly require removal and replacement. It is convenient if
grips are interchangeable so users are able to try different grips
on golf clubs to see which grip is most effective for them. In one
embodiment of the instant apparatus, grip removal can be
predetermined to be difficult in order to avoid accidental
separation during use. In yet another embodiment, removal and
replacement may be render effortless in order to allow a golfer to
test different grips and see which grip feels best.
[0045] Moreover, the ability to readily change grips may be
especially important for putter use, as this feature would lend
golfers the ability to test a thicker or thinner grip.
Additionally, although the herein embodiments of gripping
mechanisms have been highlighted, the instant system and all
embodiment thereof may be readily adapted for attachment of a club
head to a shaft in an identical manner and, this is extremely
important when golfers would like to try different combinations
grips, shafts, and club heads.
[0046] It is an object of the present system to additionally
introduce and employ several techniques for the quick exchange of
grips and club heads in order for customer in a store to assess
different grips, shafts, and club heads to determine which
combination best suits the customer at the time of purchase. The
customer will more likely buy a club if the feel is better based on
the grip, shaft control, and head performance. Determining which
combination is better achieved by trying different components. In
addition, if a customer determines that they do not like the grip,
shaft, or club head after the purchase of the golf clubs they have
the opportunity to easily return and exchange them with others.
[0047] It is also an object of the present system to reveal a
series of easy exchange techniques to be utilized as grips, shafts,
or club heads wear, allowing for easy replacement of old worn grips
with new ones, particularly as grips wear out several times a year
for many golfers. Presently, the replacement of old worn grips is
accomplished by a professional club manufacturer or by the golfer
himself. If a golfer attempts to perform the replacement, the cost
is reduced as the cost of profession labor is eliminated, however,
the process is long and difficult, which is why most golfers do not
change their own grips.
[0048] It is a primary object of the present system to introduce
the concept of interchangeable components, especially grips, which
results in the ease of placement and potential cost savings, which
will inherently result in greater profits for golf companies and
courses. It will also provide a better brand of golf clubs for the
user as the ability to have fresh grips and heads, without having
to wait for a professional to perform replacement, will enable
players to always possess their "A-game."
[0049] It is an object of the present system to reveal and review
techniques which allow exchangeable and interchangeable grips,
shafts and club heads that can include snap, screw, Velcro,
interlocking, channels, Morse taper, friction or like methods of
joining and disconnection parts quickly. It is a further object of
the instant system to introduce several manners or methods in which
components may be constructed to facilitate quick exchange.
[0050] It is a further object of the instant system to introduce
and review a first manner or method in which components may be
constructed to facilitate quick exchange wherein a shaft may be
composed of uniform construction such that each end facilitates the
technique of removal. This can include retro fitting to existing
clubs with no shaft alteration. It is a further object of the
instant system to introduce a second manner or method in which
components may be constructed to facilitate quick exchange wherein
a shaft is constructed and altered after construction such as
placing holes, grooves, threads, taper, slots, projections or the
like.
[0051] It is a further object of the instant system to introduce
and review a third manner or method in which components may be
constructed to facilitate quick exchange wherein an existing shaft
is cut and inserts into the shaft are placed or inserts are placed
into or onto a shaft without cutting. In one embodiment, a shaft
may have a groove, slot, dimple or like placed into a shaft during
manufacture or altered after manufacture for provide the desired
result. In an additional embodiment, a shaft may be cut and an
insert fitted and glued with materials such as epoxy, which are
used to hold club heads to shafts.
[0052] It is an additional object of the instant system to
introduce and review a method for providing the consumer with a
point of purchase system wherein the consumer can purchase the
sports equipment gripping mechanism, and particularly a golf club
grip, that ca be chosen to fit the consumer's requirements via the
ability to interchange/exchange numerous grip types and sizes.
Thus, the consumer can get in the store and complete the purchase
of the grip and club of his choice within a matter of minutes, even
as few as ten minutes.
[0053] It is an object of the instant system to introduce and
review techniques for the quick exchange of grips, such that a
customer in a store can try different grips and determine which
grip and feel is most desirable at the time and point of purchase.
As the consumer will be more likely to purchase a club if the feel
is better based on the grip. Such a purchase is better achieved
when the user possesses the ability to test different grips right
at point of purchase. In addition, a consumer may determine that he
does not like the grip after purchase of golf clubs and has the
opportunity to easily return and exchange it with another
interchangeable grip.
[0054] It is an object of the instant system to provide an easy
replacement and exchange system which, when grips wear, affords the
easy replacement of old worn grips with new ones. The replacement
of old worn grips is accomplished by a professional or by the
golfer himself. If the golfer does the replacement, the cost is
reduced as the labor of a professional is eliminated. There is the
ease of placement and a potential cost savings for the golfer. In
addition, golfers will change grips more often for better play and
in turn increase profits for companies.
[0055] Presently, a golfer must bring clubs to a professional to
perform the re-gripping process. There are several disadvantages to
this as the golfer must drive to the facility to both drop off and
pick up the clubs. There are potentially several days a golfer is
without the use of his clubs.
[0056] In the instant system, the techniques to allow exchangeable
and interchangeable grips can include differential or reversible
adhesives, snap, screw, Velcro, interlocking, tapers cut from a
Morse taper, frictional or like methods of joining and
disconnection parts quickly. The present invention combines these
techniques, including friction and compression, with interlocks
that secure the method of holding by blocking the path for
disengaging. For example, a snap fit is covered with a second
component which is threaded or snapped into place. For removal or
unsnapping, the second component is removed and then the snap or
the like is disengaged.
[0057] It is an object of the instant system, in one embodiment to
disclose a shaft of uniform construction, altered after
construction, where cuts and inserts are placed into the shaft. For
example, a shaft may have a groove, slot, concavity, or the like
placed into a shaft during manufacture or it can be altered after
manufacture to provide the desired result. A shaft can be cut and
an insert glued with materials, such as epoxy, used to hold club
heads to shafts.
[0058] It is an additional object of the instant system, in one
embodiment, to disclose and review a device wherein each
manufacturer may possess a specific design configured so that only
that designer's grips fit their clubs. In such a manner, the profit
loss of others providing replacements is eliminated. There is more
profit for the manufacturer of the club. For example, if Ping has a
putter and Callaway has a putter, the interchangeable grips would
have different configurations such that grips of Callaway do not
fit a Ping putter and vice versa. This would eliminate companies
which make grip replacements.
[0059] It is desirable, and included, in the present invention to
replace grips on existing clubs without altering the existing
shaft. A grip and the underlying adhesive tape on an existing club
are removed. The grip of this invention is placed on the shaft and
a threaded component applies pressure to an underlying component to
create a tight frictional fit, such as a compression member.
[0060] There has thus been outlined, rather broadly, the more
important features of the versatile golf club embodiments in order
that the detailed description thereof that follows may be better
understood, and in order that the present contribution to the art
may be better appreciated. There are additional features of the
invention that will be described hereinafter and which will form
the subject matter of the claims appended hereto.
[0061] In this respect, before explaining at least one embodiment
of the invention in detail, it is to be understood that the
invention is not limited in its application to the details of
construction and to the arrangements of the components set forth in
the following description or illustrated in the drawings. The
invention is capable of other embodiments and of being practiced
and carried out in various ways. Also, it is to be understood that
the phraseology and terminology employed herein are for the purpose

[0062] These together with other objects of the invention, along
with the various features of novelty, which characterize the
invention, are pointed out with particularity in the claims annexed
to and forming a part of this disclosure. For a better
understanding of the invention, its operating advantages, and the

[0107] FIG. 1 shows a grip 1 that has a central hole or access
aperture 8, through a longitudinal substantially cylindrical cavity
4. A snap lock mechanism 6 possesses a projection 7, which may be
an optional feature and may not be required in all circumstances.
The shaft 10 has a main stem 12, a first inclined plane 15 and a
second inclined plane 18, and a projection lock 20. The shaft 10 is
positioned into the grip 1 through the access hole 8 or aperture
until the main stem 12 is fully seated into space 4. The snap lock
6 slides down the main stem 12 and engages the second inclined
plane 18, expanding the snap lock 6. As grip 1 is pressed further
into position, the second inclined plane 18 is engaged by the snap
lock 6. The snap lock 6 is squeezed together forcing the grip 1
downward. When fully seated, the first inclined plane 15 is against
the snap lock 6, which prevents separation of the grip 1 from the
shaft 10. When the projection 7 is used, it creates a firm lock
into the indentation 20. The projection 7 may be round, square,
triangular, oval, rectangular, or any usable shape depending on how
much retention is required to hold the grip 1 on the shaft 10.
[0108] FIG. 2 shows a grip shaft assembly 30 consisting of a grip
32, insert 34 and shaft 38. Because the grip 32 may be constructed
from a rubber like material, engagement into locks, snaps, grooves,
etc. it compresses easily and deforms with time. Using an insert
constructed of metal, plastic, ceramic or other hard material or
combinations of materials provides less compression and a firmer
grip retention. Snap lock 36 uses combinations of sizes,
inclinations, indents, projections to provide adequate long term
retention.
[0109] FIG. 3 shows a grip shaft assembly 40 constructed of a grip
42, insert 44, shaft member 45, and separate snap lock 46. The snap
lock 46 may be separated from the insert 44 or can be contiguous of
the same or differing materials. The cross section reveals
different configurations shown at cross section 60, cross section
62 and cross section 64. A rubber like material grip 50 surrounds
the insert 52. The insert 52 may be contiguous or divided into
segments divided by open spaces 56. The open spaces 56 may be
filled in with other materials. There may be as few as two segments
or as many as hundreds. Furthermore, FIG. 3A illustrates the shaft
member 45 wherein the shaft possesses a non-uniform area 54 for
attachment of the removably attached reusable grip member.
[0110] FIG. 4 shows a grip shaft assembly 70 consisting of a grip
72, insert 74, shaft 76 and snap lock 77. The snap lock 77 consists
of the grip area 80, circumferential band 82, insert area 84, and
shaft area 86. Cross section of snap lock 77 at line 78 reveals
cross section 88. Cross section 88 shows circumferential grip 80,
circumferential band 82, insert 84 and shaft section 86. The
circumferential band 82 provides added or all the compression to
the inserts 84. The inserts 84 may be a single unit or divided into
multiple sections. The circumferential band 82 can also engage
portions of the shaft 86 to create further retention. Cutting or
releasing the circumferential band 82 allows removal of the grip 72
from the shaft 76.
[0111] FIG. 5 shows a grip 92 and a shaft 94 assembled as grip
shaft 90. The shaft 94 can have an oval cross section 100, round
cross section 102 or a cross section any shape. The shaft 94 has
indentations 96 which may be circular grooves 96 or dimples 99.
[0112] The grip 92 has extensions 98 which fit into the
indentations 96 of the grip 92 to provide retention. Extensions 98
of the grip 92 are pressed into place as a grip is placed onto the
shaft 94 which is tapered, parallel or reverse tapered. Extensions
98 of the grip 92 are positioned into the indentations 96 of the
shaft 94 by parts compressing or expanding as downward force is
applied and then released into position. Alternatively, the
surfaces of a shaft and grip are covered with spheres or ribs which
press past each other. The internal surface 108 has spheres of ribs
104 attached to the inner surface of a grip or insert which
compress past spheres or ribs 106 attached to a shaft outer
surface.
[0113] FIG. 6 shows a golf club 110 with a shaft 118 and a grip
112. Shaft 112 has ant rotational and retention grooves 116 and ant
rotational top groove 114. The anti-rotational wings 120 provide
potential retention and resistance to the grip 112 rotating around
the shaft 118. The grip 112 has matching internal features to fit
into the features previously mentioned on the shaft 118
surface.
[0114] FIG. 7A shows the golf club shaft grip wherein embodiment of
the golf club shaft grip 124 and alternative 140 is in the
tightened position. The golf club shaft grip 124 secures and
detaches grip 128 and insert 132 to the shaft 136 by tightening or
loosening the screw 130 which drives the insert 132 up or down to
engage or disengage snap 146. FIG. 7B illustrates an embodiment of
the golf club shaft grip 140 has the screw 126 which provides added
security that the grip 142 will not disengage from the shaft 144
during swing motions by disengaging the snap 148.
[0115] FIGS. 8A and 8B illustrate a golf club 150 with a grip 154
and shaft 159 secured by a snap 158. The snap 158 is engaged and
disengaged by tightening or loosening the screw 152 with a screw
driver 156. The top of screw 160 of the golf club 162 can have any
shape to provide adequate torque such as a slot, hex, square, star
or the like.
[0116] FIGS. 9A and 9B shows a shaft/golf club 170 which accepts
placement of the golf grip insert attachment 172 through an opening
180. Shaft/golf club 170 is an existing golf club which has been
cut shorter to accept an insert 176. A portion 178 of the snap grip
172 is placed into the cut shaft 182 through a hole or an aperture
180. It is secured by adhesive cements or the like. Assembled club
174 shows snap grip 172 cemented into shaft 182.
[0117] FIGS. 10A-10C show an internal snap system which includes a
shaft 186, locking pin 188 and grip 200. The shaft 186 has a snap
lock 194 attached to or integral with the lower shaft 196. Shaft
186 is inserted into the grip 200 through an opening 202 and
pressed into position until the snap lock 194 engages the internal
grip lock 204. FIG. 10B illustrates the sub assembly 190 prior to
addition of the locking pin 198. To secure the snap lock 194, a
locking pin 198 is placed though an opening 204 of the grip 190 and
between extensions of the snap lock 194 to prevent compression and
release. The locking pin 198 is removed, if desired, to allow
removal of the grip 190. FIG. 10C illustrates the overall assembly
192.
[0118] FIGS. 11A-11C show a grip and pegs which fits over the shaft
210. The shaft 210 has a slot 222 with side slots 224. FIG. 11B
illustrates the sub assembly 212 prior to fitting over the shaft.
The side slots 224 have dimples or indentations 218 and 216. The
grip 228 has pegs 226 on the inside of the grip 228. The pegs 226
slid down slot the 222 of the shaft 210 and line up with slots 224.
The grip 228 is rotated into slots 224 and engages the dimples or
indentations 218. Golfers are right handed or left handed so the
orientation is dependent on the force of one or the other. A right
handed golfer swings a golf club such that forces are pulling a
shaft out of a grip and as the club strikes a ball force are
rotational such that the shaft wants to rotate clockwise. The side
slots 224 have a distal wall which stops rotation in a clockwise
direction. However, forces are minimal to none in a counter
clockwise direction during use. Applied force in a counter
clockwise direction disengages the pegs 226 from the dimples 218 of
the side slots 224 so a grip can be removed. In addition, the pegs
or projections can run the length of the slot 222 and engage walls
in the slot for stronger resistance. FIG. 11C illustrates the
overall assembly 214.
[0119] Additionally the use of a form of tension applying and
retaining mechanism, such as a spring or torsion bar at the top of
the shaft and inside of the grip, may be used to offset the
difficulty in obtaining manufacturing tolerances. The use of this
design can be combined with other versions to create the proper
resistance and retention. Snap locks 224 and 226 can be different
sizes or placed a different intervals for different golf club
manufacturers such that only their golf grip fits their brand of
golf club. There may be different distances, offsets, or numbers to
make each individualized.
[0120] FIG. 12 is a similar design of the grip shaft snap
connection of FIG. 11. However, the internal portion has screw like
threads 232 to tighten the grip to the shaft as it is rotated.
Threads 242 within the grip 238 slides down the channel 230 of the
shaft 236. The threads 242 and channel 240 of the grip 238 are
rotated into the threads 232 of shaft 236 until the extension
sphere 246 engages the dimple 234 to provide retention.
[0121] FIGS. 13A-B exemplify a shaft 290 which fits into grip 301.
The shaft 290 has a top surface 293, an opening 292 to a vertical
groove 298, which opens to a horizontal groove 296 to a vertical
groove 294. The grip 301 has tabs 306 which slide down the vertical
groove 298, into the horizontal groove 296, and up the vertical
groove 294 during placement. The grip 300 has a cushioned inner
surface 308 producing a soft feel while golfing and an accurate
fit. During placement, the tabs 306 slide down the slot 298 until
the top surface 293 of the shaft 290 hits the top inner surface 302
of the grip 300. FIG. 13B illustrates the overall assembly 301.
[0122] The elastic area 302 stretches as downward force continues
allowing tabs 306 to engage the horizontal slot 296 until the
horizontal slot 294 is engaged at which point the elastic layer 302
shortens lifting and holding the tabs 306 into the horizontal slot
294. To remove the grip 301 from the shaft 290, downward pressure
and rotation disengages the components. The slots in the shaft 290
may be curved, dimpled or be of various shapes.
[0123] Referring to FIG. 14, golf club 402 has a grip 406, shaft
408 and club head 412. The shaft 408 has a lower portion 410 which
attaches to the club head 412 and an upper portion 404 which is
covered by the grip 406. The upper portion 406 of the shaft 408
provides a means for the grip 406 to be removed quickly. Common
techniques include reversible glues such as thermoplastic glues,
screws, snaps, Velcro, interlocking, morse taper, frictional, or
like methods of joining and disconnection can be used. Methods may
be combined, such as using snaps or interlocks further secured with
a screw from the top, side, or bottom. The grip 406 is easily and
quickly removed from the upper portion 404 of the shaft 408. Grips
414, 416, 418 and 420 are designed to fit onto the upper portion
404 of the shaft 408 in the same manner as grip 406. Grips 414,
416, 418 and 420 vary by material, size, shape, color, design,
aesthetics, combination of material, cord, etc. A golfer would
select the grip that feels the best and use it. There could also be
a method of securing a grip permanently or more securely if
desired. The golf club heads 407 and 411 are joined to a shaft in a
similar manner as describe for grips.
[0124] Referring to FIG. 15, the golf club 422 has a grip 424
mounted onto an insert 426 in such as fashion as to be easily
exchanged or interchanged. An insert which has a lower portion 428
that fits into an opening 430 of the shaft 432 connecting the head
434 is removably attached via any of the mechanisms mentioned
herein including, but not limited to snaps, depression peg
fittings, slideably disposed pegs, snap locks, sliding channel
technology comprising threads down a shaft, and additional
technology such as extension spheres engages dimple member to
provide retention, wherein the shaft may tapered, parallel, or
reverse tapered.
[0125] Referring to FIGS. 16A-B, the insert 436 is constructed of a
size to fit into the opening hole 440 of the shaft 443 of golf club
438. A cut out exposes the inside of the shaft 443. The golf club
444 shows the insert 436 placed inside the shaft 443 to provide
mechanisms to provide reversible retention of a grip. Each
manufacturer can have a specific design configured so only their
grips, shaft, and club head fits their clubs.
[0126] The profit loss of others providing replacements is
eliminated. There is more profit for the manufacturer of the club.
For example, if different companies market and sell, than the
interchangeable grips, shafts and club heads could be manufactured
to possess different configurations such that grips, shafts, and
club heads of one company wouldn't fit the grips, shafts, and club
heads of another company. This would eliminate companies which make
grips from supplying replacements.
[0127] The simplest and perhaps the best opportunity for
implementation of this concept may well be with putters. The
ability to have different grips and different club heads connected
with different length shafts creates an exponential number of
choices for the user. Just as different golfers require different
putter lengths, many different golfers desire different grip sizes,
shapes, appearances, as well different putter heads. Therefore,
retail stores and pro shops would be required to stock different
grips, shafts, and club heads, which would require minimal space
when compared to the same number of putters, to achieve similar
results.
[0128] Referring to FIGS. 17A-B golf grip, the insert shaft
assembly 460 consists of the shaft 470, insert 466, grip 464 and
key lock 462. They key lock 462 consists of a key 476, constriction
474 and top 472. The top 472 may be plain or decorated with
designs, owners name, phone number (in case of loss or theft) or
the like. The grip 464, insert 466, and shaft 470 have a central
hole designed to match the cross section of the key 476 or key lock
462, designed to provide anti-rotation of components and accidental
disengagement with shapes such as square, rectangular, oval, star,
or the like. The key lock 462 is placed through the hole 480 of the
grip 454 until constriction 474 passes through grip material to
engage the lower boarder to provide retention for the key lock
462.
[0129] Referring to FIGS. 18A-E, one embodiment of the golf grip
mechanism is illustrated. The instant embodiment solely employs
compression, friction fit, or friction force fit principles,
without the presence of additional mechanisms such as snaps,
cavities, indentations or any other retaining apparatuses, in order
to restrain, and release, sports clubs, sticks, shafts, and bats
within the grip mechanism. The use of the compression/friction fit
system herein allows for the quick and easy exchange, or
interchange, of sports grips on existing shafts, with absolutely no
alteration to existing sports clubs, sticks, shafts and bats,
whatsoever, due to the inherent properties of compression and
friction restraint.
[0130] FIGS. 18A-E thus illustrates the golf club grip insert
system 502 which nimbly slides over the shaft 504 and is secured
with a compression member 506, compression mechanism. The grip
insert system 502 may comprise a grip material 512 which is the
normal grip material utilized in the state of the art of practice,
or any similar material, and the insert 514 may be constructed of
any rubber, polymer, plastic, composite, metal, alloy or like
materials. The grip material and the insert material may stiffer in
chemical composition and the grip material may comprise a greater
stiffness than the insert material.
[0131] Securing the end 516 of the insert 514 of the grip insert
system 502 comprises a threaded surface 517 and end securing
projections 518. The end projections 518 may be forced tightly by a
squeezing action onto the shaft 504 surfaces when the compression
member 506 is thread with threads 520 over the securing end 516 to
create a strong frictional force resulting in a secure grip to the
shaft. As the compression member creates a high coefficient of
friction with the shaft material, the need for further restraint is
vitiated.
[0132] Further investigating the set of end projections 518, these
projections may comprise as few as one projection or as many as one
hundred. The end may also comprise one solid circumferential piece.
A partially assembled golf grip 508 shows the grip insert system
502 slid over the shaft 504 with the compression member 506 slid
over the shaft 504 ready to slide up the shaft to engage and be
threaded over the grip insert system 502. An assembled golf grip
510 shows partially assembled golf grip 508 with the compression
member 506 threaded over the golf club grip insert system 502. The
amount of resistance to movement of the grip system 502 on the
shaft 504 will be proportional to the surface area of the
projections 518 and the amount of compression created. The amount
of compression created will be proportional to the amount of force
used to thread compression member 506 which can be augmented by
utilizing a utensil such as pliers or like device for leverage.
[0133] The compression member 506 may be partially tightened for
quick exchange during trials of various grips and once a grip is
selected, it is secured with a leverage device 523 by engaging the
matching shaped end 521 at 522 of the compression member 506 such
as pliers, wrench or the like.
[0134] Referring to FIGS. 19A-E, in an embodiment designed to
augment the friction fit capabilities of the instant system, the
golf club grip 526 comprises a grip material 530 (which constitutes
the normal state of the art material utilized today), insert 534,
liner 532 and stabilizing projections 536. The liner 532 is
optional for improved engaging properties as the insert must slide
over a shaft. The compression member 528 threads over the end of
insert 534 to secure the grip insert 526 onto the shaft 540. The
shaft 540 has a concavity 542 that accepts the projections 536 of
the insert 534 to provide retention and resistance forces from all
directions including dislodging, multi-degree of freedom, and
rotational forces when the grip is joined to the shaft. FIG. 19C
illustrates the sub assembly 546. The end portion 529 of the
compression member 528 can comprise a recessed area shaped to
accept a wrench tightening mechanism or wrench tightener or
tightening mechanism 531 if required to resist forces, though this
is optional.
[0135] The projections 536 further engage the concavity or concave
areas 542 in a snap engagement. FIG. 19D illustrates the sub
assembly 552 and qualifies as an exploded view showing the
projections 536 of the insert 534 engaging the concave areas 542 of
the shaft 540, outer retaining mechanism 550 and the compression
member 528 thread over the end of insert 534 preventing the
projections 536 from pulling out of the concave areas 542 by
covering them. The concave areas 542 and projections 536 can be a
variety of shapes in the state of the art, including, but not
limited to round, rectangular, triangular, square, polygon, flat or
any shape that can provide resistance to movement.
[0136] Referring to FIGS. 20A-D, in an additional embodiment
designed to augment the friction fit capabilities of the instant
system, the grip 556 system may comprise an insert 558 with concave
areas 560 and projections 561 at the end. The interlock 562 has
snap projections 564 which engage the snap concavity 560 of the
insert 558 when assembled. The interlock 562 slides over the shaft
566, next followed by the grip 556 sliding over the shaft 566 until
the snap projections 561 engage and snap into the snap concavity
568. The interlock 562 then slides onto the end of the insert 556
until the snap projections 564 engage and snap into the snap
concavity 560 and secure the interlock 562 onto the insert 556
which in turn covers and prevents dislodgement of the snap
projections 561 from the snap concave areas 568. FIG. 20C
illustrates the sub assembly 570 and FIG. 20D illustrates the
assembly 577. The grip 556 is secured to the shaft 566 and can only
be unsnapped if the interlock 562 is snapped off the insert
558.
[0137] Referring to FIGS. 21A-B, in yet another embodiment designed
to augment the friction fit capabilities of the instant system, the
shaft 580 may comprise the snap and stabilizing concave areas 582,
584, 586 and 588 which can by any variety of shapes. The inside of
the insert 590 has matching projections 592, 594, 596 and 598 which
stabilize the insert 590 against the shaft 80 to prevent
movement.
[0138] Referring to FIGS. 22A-C, again designed to augment the
inherent characteristics of friction fit capabilities of the
instant system the shaft 606 may possess an access hole or aperture
108 disposed to accept the shaft insert 600 at the end 604 and can
be held by friction, glue, snaps or like means. The insert 610 or
the grip may possess a secondary projection 612 which engages the
hole of the matching shape 602 of the shaft insert 600 as shown
when all assembled 614.
[0139] Referring to FIGS. 23A-C, in an alternative embodiment
designed to augment the friction fit capabilities of the instant
system, the grip insert 616 may comprise an end body 621 and a set
of projection ends 618 which can be of any shape cross section 620
and 626 as seen through line 619 to include round, oval,
rectangular, square, triangular, hexagonal, trapezoidal,
pentagonal, etc. and may be constructed of different materials such
as plastic or any suitable polymer 622, rubber 624, and composites.
FIG. 23B illustrates a top plan view of the system 620. The set of
projection ends 118 are squeezed tightly against, or utilize
adhesiveness and friction, to stabilize a grip to a shaft as
described earlier with compression member.
[0140] Referring to FIGS. 24A-B, in another embodiment designed to
augment the friction fit capabilities of the instant system, the
grip 630 consists of grip material 632 and a split insert 634
separated by a space or special air gap 636 which allows expansion
of the grip, which expands the grip material. The grip 638 shows
grip material 640 and segmented insert 644 which allows easier
adaptations to a shaft.
[0141] Referring to FIGS. 25A-B, the grip 650 and interlock 652 fit
over the shaft insert 654, which is cemented at the end 660, glued,
welded, snapped or joined by any common technique into the shaft
656, in a manner to augment the friction fit capabilities of the
instant system. The insert 654 may have various projections or
concave areas 658 that match an inert surface of a grip for
stabilization. The shaft 656 is formed or cut to the appropriate
length.
[0142] Referring to FIGS. 26A-E, in one embodiment, the system
comprises a golf grip insert 664, which includes the type of
materials normally utilized in concurrent grips, or grip material
666, an insert shell 670, and an insert liner 668. In a manner set
to augment the friction fit capabilities of the instant system, the
insert liner may include projections 674 of any shape within the
state of the art including, but not limited to, oblate, circular,
oval, elliptical, triangular, square, rhombus-shaped, trapezoidal,
rectangular, pentagonal, hexagonal, heptagon octagonal, nonagonal
and decagonal. The insert 668 can be a different material then the
grip material 666 or can be the same and material contiguous with
the grip 666 extending through holes provided by an open insert
structure comprising a pattern of apertures 671. The grip material
may comprises a different chemical composition than the insert
material and the grip material may also comprise a greater
stiffness than the insert material.
[0143] The insert 670 may extend the length of the grip or just
partial length depending on the requirements. For example, the
insert may extend three quarter of the way the last quarter the
grip material is extended so it touches or expands over the shaft.
The pattern of holes or apertures 671 allow the material of the
insert liner 668 to be contiguous with the grip material 666, which
can be varied from small holes to very large holes and of various
shapes. The projections 674 of the insert liner 668 provide a
decreased surface area to all materials which stick to the shaft
673 as it slides down into position. The projections 674 touch or
compress against the shaft 673. Present grips normally comprise a
very sticky inner surface which can limit the extent of travel or
slide down a shaft.
[0144] The projections 674 may be constructed to a dimension so
that they compress and slide down the shaft 673. The projections
674 may provide a frictional component that limits movement.
Compression of the projections 674 is inherently increased by grip
pressure in order to hold, or to swing a club. Movement of the grip
insert 664 is further limited by this compression and eliminated
when combined with compression lock 672. In FIG. 26E the set
extensions are illustrated in examples, but to be limited to,
cylindrical 676, triangular 678, or rectangular 680, to augment the
friction fit capabilities of the instant system.
[0145] Referring to FIGS. 27A-C, as illustrated, a grip insert 682
has an end 684 with extensions 680 to augment the friction fit
capabilities of the instant system. FIG. 27B illustrates view 190,
a cross sectional view taken at plane 688 illustrates a set of
cutting extensions 692 which, when tightened by compression lock
technology, drive into the outer surface of the shaft 694 creating
improved resistance to movement.
[0146] Referring to FIGS. 28A-D, as illustrated by diagram 702
consisted of a screw 700, grip 706, rib 708 and optional insert
710. Diagram 704 consists of a shaft 711 with a slot 712 which
accepts rib 708 when assembled. The grip 706 slides onto the shaft
711 and is secured with the screw 700. Diagram 714 shows assembled
grips 706 on the shaft 711 secured with the screw 700.
Alternatively, diagram 716 shows the grip 717 secured over the
shaft 718 with the screw 719, which may press against a flat
surface, into a dimple or other indentation, thread into a matching
threaded hole, or any other common method. This technique allows
the grip to slide up and down the shaft and be fixed at different
lengths so a sportsman may try different lengths.
[0147] Referring to FIGS. 29A-C, as illustrated by diagrams 720,
730 and 740, components are threaded and screwed together for quick
assembly. Diagram 720 shows the grip 722 threaded onto the shaft
724. Diagram 730 shows the grip 732 attached to the inner core 734
with the lower extension 736, which is threaded into the shaft 738.
Diagram 740 shows the grip 742 with the inner core 744. Extension
746 of the shaft 748 is threaded into the inner core 744 of the
grip 742.
[0148] In a further embodiment, the system comprises components
which produce compression, increased adhesion and or friction as
would occur with increased surface area, contact, pressure and the
like. A grip can be a single component or multiple components
designed to fit old or newly designed shafts. For example, a single
material grip with an inner shaped surface may be used. A series of
triangles such that the apex is juxtaposition to a shaft would
provide increased surface area when the triangles are compressed as
would occur when a tapered grip is pressed onto a matching tapered
shaft. Alternatively, an inner core is a hollow tube with at least
one split partially along its length which allows compression. An
outer core which is over the inner core slides up and presses it
tight against the shaft.
[0149] The movement of components against each other and or against
a shaft creates controlled compression to increase adhesion or
friction. Components are fixed into position either reversibly or
irreversibly to prevent a grip from coming off during play,
practice, demonstration or the like. Components are shaped so
minimal adhesion or friction is created during placement. Upon
final placement of components increased adhesion or friction is
created to secure a grip.
[0150] Referring to FIGS. 30A-G, a shaft, golf grip comprising an
inner and outer core and shaped surfaces, and the individual
components as well as assemblies are illustrated. FIGS. 30a-g
illustrate an outer core 802 that may comprise a hollow cylinder
which consists of a hollow cylinder 808 with opening 810. The
inside of outer core 802 is tapered with the widest part at end 818
and the narrowest at end 819. Inner core 804 is a hollow cylinder
with optional a least one split 806 preferably with multiple splits
which runs most of the length of the hollow cylinder. Splits may
run the length of an inner core, go part way, start from either end
or be placed as internal slots. The outer surface 812 of inner core
804 is tapered such that the widest part is at end 822 and the
narrowest at end 816. Inner core 804 has grooves 814 which may
alternatively be places as a circumferential indentation which
protrusion 834 of outer core 802 fits into to limit movement back
and forth.
[0151] Assembled grip consists of inner core 804 being placed into
outer core 802 by placing end 816 of inner core 804 into opening
810 of outer core 802. The opening at end 816 of the inner core 804
and the opening at the end of outer core 819 is larger than the
diameter of shaft 837 such that assembled grip slides easily over
shaft 837. Inner core 804 extends beyond opening 810 and out of
outer core 802 when assembled for placement. Alternatively, the
diameter of opening 816 of inner core 804 is slightly smaller
creating a tight fit but not enough to impede placement.
[0152] Cross section shows grip 833 placed over shaft 837 in an
inactive position. In this position, end 822 engages shaft 837 at
the butt end to provide a tight fit and provide resistance of
movement on the shaft when outer core 802 is activated by moving it
up the inner core. Outer core 802 may have extensions 834 with fit
into grooves 814 and limit motion up and down the inner core 804.
When grip 833 is fully seated onto shaft 837, outer core 802 is
forced up such that it slides up over inner core 804. The inner
tapered surface of outer core 802 squeezes the inner core taper and
presses tightly to the shaft by pressing against the tapered outer
surface of the inner core. Extensions 834 of outer core 802 go over
the end of the shaft to secure it when fully seated and block it
from sliding downward to disengage the inner core.
[0153] Additionally, grooves 840 of inner surface 838 of outer core
804 matches to grooves 842 of outer surface 836 of inner core 804
and provide resistance to forces at the interface of the two cores
to resist rotation. The surfaces may be rough, dimpled, or any
other common method of providing mechanical resistance. In
addition, the rough surfaces allow less friction when outer core
802 slides over inner core 804. The cross section of the inner core
and outer core may be out of round to minimize spinning when
rotational forces are applied.
[0154] When grip 820 is located in its final position, the outer
core 802 is secured by friction, snaps, pins, screws, set screws or
other common means to the shaft and or the inner core 804.
Compression of inner core 804 increases forces of friction either
by increasing force and or increasing surface area contact and or
adhesion.
[0155] Now, referring to FIGS. 31A-D, cross section views of
possible shaft and core configurations at the interfaces are
illustrated. FIGS. 31A-D, cross sections show various cross
sections of cores, core layers, and/or shaft surfaces. The cross
section shows inner surface of inner core 852 with surface
protrusions 854 shaped round. The protrusions 854 may be hollow or
solid and are designed to contact the protrusions 858 of shaft 856.
The protrusions are constructed in a similar manner between inner
and outer cores. When compression is applied, protrusions 872, 854
and 858 collapse increasing surface area contact. Cross sectional
FIGS. 31B and 31C are similar in that projection 862, 866, and 855
collapses when compression is applied to cores or shaft 864, 868,
853 and 857. Also illustrated are triangular protrusions 866. Shaft
surface 857 has indentations 859 to accept protrusions 855 for
improved resistance to forces. Furthermore, FIG. 31D shows an
alternative cross section of outer core indentations/protrusions
874 to the inner core indentations/protrusions 872.
[0156] Referring to FIG. 32, a cross section shows inner core 888
with layer 886 applied and joined to it and outer core 882 with
layer 884 applied and joined to it over shaft 890. Key or screw 887
fixes cores into a final position to prevent movement and
disengagement. Layer 886 and 884 are applied as materials that can
slide effectively over each other during activation so outer core
882 compresses inner core 888. Layers are sheets of material or
coatings of material. The surface of layers and cores are smooth,
textured, patterned or the like depending on how surface texture is
going to be controlled. The preferred embodiment, all layers are
elastic enough to follow and change shape as a shaft does during
use.
[0157] Referring to FIGS. 33A-C a series of cross section views of
thread systems and layers applied to an inner and outer core,
threaded components are used to move a grip over a shaft. Outer
core 902 slides over inner core 904 when placed on shaft 906 and
turned so threads 900 move the outer core up or down inner core 904
relative to shaft 906. When outer core 902 moves up inner core 904,
the tapered surfaces compress the inner core tapered surfaces
producing an interface with shaft 906 of more surface area,
increased adhesion or increased friction that can resist forces of
play. In the preferred embodiment, inner core and outer core are
materials which is rubber like to move with the changes of shape
that a sports shaft goes through during use. The inner core is
preferably a softer material that an outer core so compression
occurs. Materials can be plastic, metal, rubber, paper, silicone,
polyether, and porcelain, materials commonly used in sports grips
and like materials.
[0158] FIG. 33B, a cross section show inner core 910, outer core
908 shaft 912 thread from one end to the other between cores. It is
understood that the treaded components can be part of a shaft as
well and interface shaft to grip. The cross section additionally
shows outer layer 914, inner layer 920 with layers 916 and 918 over
shaft 922 which are configured to allow movement, adhesion and
compression of components and can be used with threaded components.
Treaded components are turned by hand pressure, however, external
devices such as a wrench can provided added torque. Multiple layers
or coats are used to improve movement while maintaining the
properties of outer and inner cores.
[0159] FIGS. 34A-E' illustrate cross sectional views of possible
interface shapes in the decompressed (relaxed) and compressed
position. FIGS. 34A-E', exemplify the resultant materials
activities whilst the grips 933 are being placed over shaft 935.
Shaft 935 is reverse tapered such that grip 933 does not engage
shaft 935 until it is most of the way seated. Expansion of grips
933 allows placement if the force of friction is not too onerous to
allow movement. The inner surface of grips 933 can be various
textures as seen in the series of cross sections FIGS. 34B-E',
which illustrate the visual components prior to compression, as
opposed to 34B-E' which exemplify the changes in textured surfaces
when in the compressed position respectfully. The inner surface
triangular projections 936 of inner surface of grip 934 over shaft
938. Projections 936 flatten when compressive forces are applied as
the grips inner tapered surface presses against tapered outer
surface of shaft 938 as seen in cross section FIG. 34B.
[0160] FIGS. 35A-C illustrate three dimensional and cross section
views of a thread system. Referring to FIGS. 35A-C, cross sectional
views include outer core 958, 966, inner core 960, 968, shaft 962,
970 and threaded component 956, 964 which move outer cores up over
inner cores and compress the inner cores. Shaft 962 is tapered and
increases forces onto inner core 160 when compared to when parallel
shaft 970 is used. Diagram 954 shows an outer view of a grip with a
turning threaded component constructed in a manner that the
threaded component turns but the grip slides up but does not turn.
A similar technique can be done with a grip which has no layers or
cores. Threaded components are turned by hand pressure, however,
external devices such as a wrench can provide added torque.
[0161] FIGS. 36A-D illustrate cross section views of snapping
components and the threaded screw driven grip. Referring to FIG.
36A, a cross section grip assembly shows a grip with an inner core,
layer or coating prefixed to the outer core, however, alternatively
a grip is shaped the same but constructed as one piece. When forced
over a shaft, a grip moves as one unit resulting in compression
onto a shaft for increase adherence. FIG. 36B, an additional cross
section demonstrates a standalone grip (cross section on above) and
mounted grip (cross section below) shaft 985. Outer core 979 goes
over inner core 983 which when pressed over shaft 985 slides down a
tapered shaft surface with minimal contact. When the grip is almost
fully seated outer core 979 presses onto tapered inner core 983 to
compress and increase retention. Protrusion 984 of inner core 983
snaps into indentation 988 of shaft 985. Protrusion 981 of outer
core 979 snaps over inner core 983 outer edge to be secured.
Optional retaining element 990 with protrusions 992 further secures
the grip.
[0162] FIG. 36D, exemplifies a shaft 1002, a grip 999 with inner
core 998 and outer core 1000 which is moved up and down shaft 1002
by screw 996 which also provides a secure lock to prevent
accidental dislodging of grip 999 off shaft 1002.
[0163] Referring to FIG. 37, a cross section view is shown
including insert 1016 in shaft 1022 securing inner core 1014 by
snap 1020 inserting into snap 1018 of insert 1016. Inner core 1014
is secured to shaft 1022 so outer core 1012 can slide up inner core
1014 to compress it for a tight fit without inner core movement.
Insert 1024 has a threaded core so a threated component such as a
screw can secure an inner core. Inner core 1026 has an insert
constructed as part of the inner core.
[0164] Referring to FIG. 38, an assembly drawing, an inner core
1030 possesses end 1036, slots 1034 and legs 1032 as further seen
in cross section view 1031. Legs 1032 can have various shapes
included but not limited to, round oval, moon shaped, square,
rectangular, triangular, hexagonal, or like shapes. Inner core 1030
can have a variety of possible cross sections as illustrated but
not limited to 1054, 1050 and 1052.
[0165] Inner core 1040 has end 1042 which is solid with no
perforations and perforations 1044 which can be of any shape to
allow compression when an outer core presses against it.
Additionally inner core 1046 is the same as inner core 1030 but has
joining supports 1048 to limit motion of legs 1032 during placement
over a shaft or sports stick.
[0166] FIG. 39A-B illustrate weave grips and weave core alternative
embodiments of the instant system wherein FIG. 39b illustrates an
assembly drawing exemplifying the different components.
[0167] Referring to FIGS. 39A-B, FIG. 39A, shows a common
configuration of strips prior to forming a weave 1072 and also
reveals a tighter weave as formed by string like weave 1074.
Referring to FIG. 39B, an assembly drawing, a sports grip 1062
consists or a weave of strips 1068 and 1070 to form a cylinder 1066
which enlarges and constricts with less or more lengthening
respectfully. Grip 1062 is placed on a shaft such that end 1064
fits securely to a shaft end away from a head. Grip 1062 is
stretched down a shaft in the direction of arrow 1069 resulting in
the weave of cylinder 1066 constricting making the diameter smaller
and inner parts of the weave of strips 1068 and 1070 pressing tight
to a shaft.
[0168] Alternatively golf grips 1078 and 1088 show shaft 1082 and
1084 with inner core 1076 seated over them. Outer weaved core 1080
is attached at inner core end 1083 and pulled up shaft 1082 toward
end 1086 over inner core 1076 and fixed in position. The outer
weave core 1080 constricts reducing its diameter and compressing
the inner core 1076 for increase friction, adhesion, surface area
or the like for improved retention and no movement during play.
[0169] Alternatively as revealed by assembled grip 1088, an inner
core 1076 possesses outer weaved core 1092 attached to inner core
1076 at end 1094. Outer weaved core 1092 is stretched down inner
core 1076 relative to shaft 1084 toward end 1096. The outer weave
core 1092 constricts reducing its diameter and compressing the
inner core 1076 for increase friction, adhesion, surface area or
the like for improved retention and no movement during play.
[0170] Grip 1100 reveals the final position of an outer weaved core
1102, an inner core 1104 over the shaft 1090. Ends of outer weave
cores may be affixed by snaps, interlocking, glue, bonding,
adhesive, friction, Velcro, or other common techniques such as tape
or the like. Alternatively, but not preferably, adhesive tape is
applied to further a sure fixation.
[0171] A weave pattern of this invention may be used as a weave
grip alone, and or as an inner core and or as outer core or
combinations of these depending on the desired amount of resistance
required to resist forces during practice, play, demonstration and
the like. To remove a grip, the length of a weave component must be
shortened. Ideally, a distal end is fixed as the forces of swinging
a sports club pull on a weave up toward the top making it tighter.
In addition, the texture of a weave provides better feel for a
sportsman during play.
[0172] Referring to FIG. 40, a cross sectional view of inner
surface 1110 and a perpendicular cross sectional view (lower
figure) wherein the grip 1118 is used as inner or outer surfaces
1112 of a grip or shaft components. Inner surface 1110 and 1118
have adhesive materials 1114, 1120, 1122 and 1125 in wells 1127
which are placed in such a manner that that have minimal or no
contact with an adjacent surface until compression is applied.
Wells can be a variety of shapes as seen on inner surface 1118. The
walls surrounding adhesive materials are the same or extend down
further than the adhesive materials. Compression collapses well
walls such that adhesive material contacts a surface.
[0173] FIG. 41, illustrates a cross section and an exploded view
thereof, illustrating inner surface 1142 with layered adhesive
sacks 1144. Adhesive material is contained in sacks attached to an
inner surface of a grip, grip component or a shaft. When
compressive force is applied, sacks burst and adhesive glues a grip
to a shaft or component to component. The upper cross section
reveals inner surface 1142 with adhesive sacks 1144 between the
grip and shaft 1150. The lower cross section reveals an adhesive
layer 1152 resulting from the burst adhesive sacks 1144 upon
compression.
[0174] In a further embodiment designed to augment and enhance the
instant apparatuses disclosed herein, a system and concurrent
method of utilization is introduced wherein an air compressor and
accompanying air compression system may be utilized to inflate the
grip in order to afford the grip the capability to slide into
place.
[0175] It is the purpose of these systems to provide a quick easy
way to change sports stick grips so a sportsman can select a grip
which allows them to play their best, to replace grips more often
to provide better play, decrease cost of manufacture and reduction
of labor costs. Alternatively, sport stick companies can increase
profits by eliminating other companies from providing replacement
grips
[0176] Within the technology, each manufacturer may possess a
specific design configured so only their grips, shaft and club head
fits their clubs. The profit loss of others providing replacements
is eliminated and thus more profit for the manufacturer of the
club. For example, if different companies market and sell golf
clubs and one company offers golf clubs, than the interchangeable
grips, shafts and club heads could be manufactured to possess
different configurations such that grips, shafts and club heads of
one company wouldn't fit the grips, shafts and club heads of
another company. This would eliminate companies which make grips
from supplying replacements.
