Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a non-provisional application of U.S.
Application No. 61/184,524 filed on Jun. 5, 2009, which is hereby
incorporated by reference as is fully recited herein.
INVENTIVE FIELD
[0002] Exemplary embodiments of the present invention are directed
to a bow. More particularly, exemplary embodiments of the present
invention are directed to an extension grip for a bow which allows
for increased draw length that correlates into a faster arrow
speed.
BACKGROUND OF THE INVENTIVE FIELD
[0003] The velocity of an arrow, along with accuracy, are the major
contributing factors as to whether a hunter may be successful in
bowhunting. Arrow velocity and accuracy have been greatly increased
with the addition of the compound bow, which enhanced the stored
energy of bows having a peak draw force. Upon release, the full
draw of the bow is brought to bear upon the arrow and, typically,
the draw length is much greater that that which an archer could
otherwise hold comfortably during aiming.
[0004] Typically, in an effort to achieve increased arrow velocity,
manufacturers have gradually decreased the brace height by the
design of the riser on the bow. Although increases in arrow
velocity have been achieved through incremental shortening of the
brace height, i.e., the distance between the string and the low or
pivot point of the bow handle where it is braced in an archer's
hand, there is a natural limit to minimum brace height, in
conventional bows and this limit is imposed by the need for certain
amount of arm clearance. In the past, the draw length has been
achieved by changing modules, cams or self-adjustments on the bow.
Typically, the draw length increases as the brace height decreases.
In this scenario, when the arrow is acted upon over a larger
distance, for a given draw length, a longer power stroke will mean
a faster arrow speed. Additionally, some individuals that have
shorter arms and/or wingspans may have difficulty achieving a draw
length long enough to achieve desired arrow velocity for a given
bow.
[0005] As can be seen, there is a need for a device that may
lengthen the draw length and allow for a longer draw that
correlates into a gain in arrow velocity and accuracy. It is common
for the velocity of an arrow to increase approximately ten feet per
second for every additional inch of draw length. Also, there is a
need for a device that allows a pre-existing bow to be modified for
individuals with shorter arms and/or wingspans to achieve increased
velocity and accuracy by increasing the draw length. Furthermore,
there is a need for a device that may allow for adjustment of the
draw length on new or pre-existing bows by allowing lateral
adjustment of the grip. A device of exemplary embodiments may
satisfy these needs/preferences.
SUMMARY OF THE GENERAL INVENTIVE CONCEPT
[0006] Exemplary embodiments are directed to an extension grip for
a bow. Exemplary embodiments of the extension grip may be adaptable
to different styles of bows risers and/or grips. Exemplary
embodiments may be adapted to engage bow risers to replace stock
bow grips, once the grips are removed from the riser. An exemplary
embodiment of the grip extension generally includes a body that is
adapted to engage at least a portion of a grip and/or bow riser. In
one particular embodiment, the grip extension generally includes a
body that engages at least a portion of the riser of a bow, to
effectuate the replacement of a stock grip. In an exemplary
embodiment, the body may releasably secured with at least a portion
of the bow grip and/or bow riser, but not limited to, by a press
fit. Exemplary embodiments of the body may be releasably secured to
a bow riser with a securing device, such as, for example, set
screws, glue, etc.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT(S)
[0014] FIGS. 1-6 depict exemplary embodiments of an extension grip
for a bow. As shown, an example of an extension grip 10 for a bow
(hereinafter "grip") includes a body 100 that is adapted to be
releasably secured with at least a portion of a bow 200. In
exemplary embodiments, the body 100 is adapted to be releasably
secured with at least a portion of a bow riser 202 and/or a bow
grip 204. In one example, the body 100 is adapted to fit on the bow
riser 202 to effectuate the replacement of a standard bow grip.
[0015] Exemplary embodiments of the body 100 may include a first
and second end 102a and 102b. Additionally, the body 100 may
include a hand portion 104. In this embodiment, the hand portion
104 is substantially rectangular in cross-section with a rounded
outside edge in shape to facilitate grasping of the body 100 by an
individual during use thereof. However, it should be realized that
the hand portion 104 may have any number of cross-sectional
geometries that permit gripping during use of the bow 200. The
thickness of the hand portion 104 may help determine the amount of
reduction in brace height and the correlating increase in draw
length of the bow 200. In exemplary embodiments, there is a direct
correlation between the thickness of the hand portion 104 and the
increase in draw length. Some common thicknesses of the hand
portion 104 may be 1/2'', 1'', 11/2'', etc. In whatever form, the
thickness of the hand portion 104 is thicker than that of a
standard bow grip to effectuate an inexpensive, quick, and
efficient decrease the brace height and correlating increase in
draw length.
[0016] Furthermore, the increased thickness of the hand portion 104
compared with a standard grip may help an individual decrease the
likelihood that a bow to torques when aiming and shooting an arrow.
Typically, torquing may occur when an individual grasps a bow grip
with their whole palm and fingers of the hand, instead of engaging
the grip with only the portion of the web of their hand between the
thumb and index finger. Exemplary embodiments may decrease the
potential for torquing to occur by not allowing an individual to
grasp the grip with their entire hand, due to the increased
thickness of the grip 10.
[0017] The hand portion 104 may be made of any number of materials,
such as, for example, fiberglass, plastics, rubbers, metals, etc.
Preferably, the hand portion 104 has sufficient strength to permit
proper operation of the grip 10. Also, it is preferred that the
material(s) used to fabricate the hand portion 104 may resist wear
from an individual repeatedly gripping and using the hand portion
104. The hand portion 104 of the body may be provided with one or
more grip assisting features. For example, in one example
embodiment, the first end 102 may be provided with a channel (not
shown) that is adapted to allow at least a portion of an
individual's palm and/or web between the thumb and index finger to
engage the hand portion in a more ergonomic fashion. Exemplary
embodiments may further include a knurled texture (not shown) to
further facilitate gripping by an individual. In other embodiments,
a variety of other textures and/or treatments for improving grip
and facilitating ergonomic fit to an individual's hand may also be
applied.
[0018] As best illustrated in FIGS. 3 and 4, exemplary embodiments
of the body 100 may include first and second side portions 108a and
108b secured to at least a portion of the hand portion and form a
channel 110 that runs through at least a portion of the body 100.
In exemplary embodiments, the side portions 108a and 108b may be
positioned so that the channel 110 formed thereof snuggly engages
at least a portion of the bow riser 202 and/or the bow grip 204 to
effectuate a press fit.
[0019] In one example, the channel 110 formed from the side
portions 108a and 108b narrows in width from the exterior to the
interior of the channel 110 to help effectuate a press fit, yet
allow the outer edge of the channel 110 to encircle at least a
portion of the bow riser 202 and/or the bow grip 204 when secured
thereto. In another example, the channel 110 may widen in width
from the exterior to the interior of the channel 110 to help
effectuate a press fit that allows the body 100 to snap onto at
least a portion of the bow riser 202 and/or the bow grip 204 when
secured thereto.
[0020] The side portions 108a and 108b may be fabricated from
various materials including, without limitation, fiberglass,
plastics, rubbers and metals. The side portions 108a and 108b may
be constructed from the same or different material than the hand
portion 104. Additionally, the side portions 108a and 108b may be
integral with the hand portion 104 in exemplary embodiments,
allowing fabrication by molding or similar methods. However, in
other embodiments, the side portions 108a and 108b may be
individually fabricated and secured with the hand portion 104. In
another example, mirror images of the first side portion 108a that
is integral with one half of the hand portion 104 may be secured
with the other mirror image of the second side portion 108b that is
integral with the other half of the hand portion 104.
[0021] It can be understood that the grip 10 may further include a
securing device that facilitates releasably securing the body 100
to at least a portion of the bow riser 202 and/or the bow grip 204.
As shown, this particular grip 10 may be releasably secured to a
portion of the bow grip 204, and at least one set screw (not shown)
may be provided to releasably secure the body 100 to the bow 200
once set. Although this embodiment uses two set screws 120 that
protrude through each side portion 108a and 108b, other embodiments
may use any number of set screws that protrude through other
portions of the body 100 to help facilitate releasable
securement.
[0022] In alternative embodiments, depending upon the material used
to construct the body 100, and/or other design and operational
factors, other securing devices may be used to secure the body 100
to at least a portion of the bow riser 202 and/or bow grip 204,
including, but not limited to: threaded or non-threaded fasteners,
with adhesives, etc. In one particular example, double-sided tape
(not shown) may be secured with a least a portion of the channel
110 to facilitate securement. In another example, an adhesive may
be applied to at least a portion of the channel 110 to facilitate
securement. Other types of securing techniques may be used in
exemplary embodiments of the grip 10.
[0023] Exemplary embodiments of the grip may include at least one
shim (not shown). In some embodiments, the shims allow for varying
the draw length of exemplary embodiments of the grip when secured
with the bow 200. In this manner, the draw length of the bow 200
may be easily adjusted to accommodate different users. The shims
may be adapted to fit within the channel 110 of the body 100 and
engage at least a portion of the bow riser 202 and/or the bow grip
204 when secured therein. In one example, multiple individual shims
may be different thicknesses (i.e. 1/4'', 3/8'', 1/2'', etc.) to
allow for increase adjustability of the draw length. However, in
another example, multiple individual shims may be the same
thickness and stacked upon one another to achieve a desired draw
length.
[0024] The shims may be made of any number of materials, such as,
for example, fiberglass, plastics, rubbers or metals. Preferably,
the shims have sufficient strength to permit proper operation of
the grip. Also, it is preferred that the material(s) used to
fabricate the shims may resist compressive forces to allow for
proper draw length. Once installed with a bow 200, the grip 10 may
allow for adjustment of the draw length.
[0025] As aforementioned, exemplary embodiments of the grip 10 may
be secured to at least a portion of a bow riser 202 for use
thereof, as best depicted in FIGS. 5 and 6. In one example, the bow
grip 204 of a standard bow 200 may be removed. In some exemplary
embodiments, the aforementioned adhesive may be applied to at least
a portion of the side walls 108a and 108b and/or the bottom of the
hand portion 104 within the channel. Next, the body 100 of may be
placed around at least a portion of the riser 202 is placed within
the channel 110 of the body 100 and the side portions 108a and 108b
engage at least a portion of the riser 202. After the body 100 is
properly positioned, the set screws or other securing device may be
tightened to provide additional securement of the body 100.
Furthermore, in some embodiments a string tamer may be applied to
the bow 200 to help assure that the string does not strike an
individual's hand once the arrow is released.
[0026] While certain embodiments of the present invention are
described in detail above, the scope of the invention is not to be
considered limited by such disclosure, and modifications are
possible without departing from the spirit of the invention as
evidenced by the following claims:
