BACKGROUND OF THE INVENTION
 (A) Field of the Invention
 This invention relates to an improved finger grip used with
all types of firearms, sporting implements, hand tools and the like
and more particularly, but not by way of limitation, to an ergonomically
designed finger grip enhancer for mounting on a firearm or a hand
tool for improved grip and for helping prevent slippage on the item.
 (B) Discussion of Relevant Art
 It is well known to provide hand grips on the handles of
various types of tools and implements to obtain a comfortable feel
as well as to reduce or eliminate the torsional movement between
the handle and the hand of the user. Hand grips such as the types
used on power tools or bicycle handle bars are often contoured according
to the finger surfaces to aid the user or rider in maintaining a
 In the United States, there are a number of manufacturers
making handgun extensions, grip enhancers, rubber grips and like
accessories for firearms. Also the prior art grip enhancers can
include one or more finger swells between gripping fingers. Further,
gunsmiths can improve a gun owner's grip by roughening the gripping
surface, along with adding bulky stocks or by providing finger swells
by expensive welding with refinishing.
 For example, U.S. Pat. No. 4930181 discloses "auxiliary
tool handles" for removable, adjustable attachment to cylindrical
tool handles such as used for garden rakes, hoes and the like. The
auxiliary handles comprise at least one curvilinear handle segment,
which can be attached to the tool handle by slidable sleeves. The
auxiliary handles can be installed substantially perpendicular to
the straight tool handle. This patent also discusses the forces
and fatigue factors involved in using various types of hand tools.
 U.S. Pat. Nos. 4785495 and 5155878 to Dellis disclose
moldable hand grips for use with cycle handlebars, tools, guns and
the like which can be custom molded to fit the contours of a particular
user's hand. The grips can include special surface properties for
comfort and adhesive and resilient inner layers for enhanced function.
 U.S. Pat. No. 4599920 discloses a "power grip insert"
which is attachable to either a handled instrument or a user's hand,
with one side contoured to accommodate the handle shank to be gripped
and an opposing side contoured in accordance with the musculature
of the palm of the user's hand. The insert can be permanently attached
to a glove for use with golf clubs. This patent provides an extensive
discussion of the anatomy of the hand and the need to adapt the
grips of various handled instruments to minimize stress and fatigue
 U.S. Pat. No. 6073381 discloses a "universal thin
walled finger groove adapter" for handguns, comprising a thin
ductile metal reinforcing plate encapsulated with thin front and
back layers of elastomeric material. At least one finger groove
projection is provided on the front surface of the adapter. The
adapter is molded in a flat condition, may be trimmed in that configuration
to a variety of shapes for mounting on various different handgun
handles, and is deformed into the appropriate shape for mounting
to the handgun by the user. The adapters are said to be well suited
for handgun users with small hands. This patent discusses grip factors
important to the effective use of firearms.
 U.S. Pat. No. 5857279 discloses an ergonomically deformable
grip for firearms, which is made of elastomeric material to obtain
a basic contour at the front of the grip through a series of flexible
projections formed from the material. The projections can be similar
to thin ribs separated from each other by narrow spaces, over which
the fingers of the user's hands support themselves. This patent
discusses prior art handgun grips and their shortcomings. The deformable
grips disclosed therein seem suitable for accommodating hands with
fingers of various sizes. However, it would appear to do this without
providing the benefit of a stronger grasp, since the ribs would
have to be too flexible to provide adequate support from the upper
and lower surfaces of the fingers. Thus, resistance in a vertical
plane, as during gun recoil or hitting the holster during the draw,
would probably not be substantially improved.
 Despite the numerous patents in this field, there remains
a need for simple, inexpensive devices which can be used to improve
the user's grasp upon the grips of hand tools in general, and firearms
in particular. For example, the rubberized sleeves fitted with finger
grooves for handgun grips have a detrimental effect on the esthetics
of the firearm, since they cover parts of the grip which are normally
made of wood. Such sleeves thicken the handgrip area, making it
harden to conceal when holstered. Such sleeves can also make repositioning
of the grip hand difficult during the draw, if a less than ideal
position was obtained in the holster. In contrast, the devices of
the present invention have the benefit of properly positioning the
fingers as the gun is grasped in the holster. Since the rotation
of the gun upward during the draw before the barrel has cleared
the holster can result in the weapon falling to the ground, the
present invention reduces this risk by providing a stronger grasp,
especially in the plane of such a force as hitting the holster.
Many prior art devices such as the sleeves described above are model
specific, thus requiring gun stores and manufacturers to maintain
large inventories of devices to fit numerous gun models.
 None of the above mentioned prior art firearm grip enhancers
provide the unique structure, function, objects and advantages of
the present invention as described herein.
SUMMARY OF THE INVENTION
 In view of the foregoing, it is a primary object of the
invention to provide a finger grip enhancer made of flexible or
resilient high friction material or rigid high friction material,
which conforms easily to the grasping fingers to improve control
of a firearm, hand tool or the like. The high friction material
may be plastic, metal or other suitable materials.
 Another object of the invention is to provide a finger grip
enhancer that is inexpensive and can be quickly and easily attached
using adhesive or other suitable attachment means to a selected
location on various handguns, firearms, tools and the like for increased
 Still another object of the invention is to provide a plurality
of finger grip enhancers for receiving two or more fingers thereon
for improved gripping on a handgun grip or tool handle.
 The present invention provides finger grip enhancers of
various configurations which can be installed singly or in combination
upon the handles or handgrips of various tools, sporting implements,
mobility aids and firearms to provide ergonomically enhanced grips.
The finger grip enhancer includes a finger grip body having a top,
a bottom and a flat or curved (concave) back surface. The back surface
is preferably adapted for receiving an adhesive and attaching the
grip enhancer onto a selected location on the firearm or a grip
of a hand tool. The grip enhancer is made of or comprises a flexible,
resilient or rigid material, preferably having a high coefficient
of friction for an improved gripping surface. The finger grip body
also includes an ergonomic shaped front finger surface. The front
finger surface includes a top portion tapered downwardly and outwardly
into a lower knob portion. The lower knob portion is designed to
rest against the bottom of a finger and prevent slippage thereon.
 The grip enhancers of the present invention provide nearly
universal means for improving the physical interface between the
human hand and the grips, handles and the like for most hand-held
tools, weapons and the like. The improvements are provided by a
more secure grasp of the handles or grips through an increase in
hand-grip contact area, together with reduction in the stress and
fatigue caused by the exertion required to maintain the grasp through
hand strength only. Most common grip designs for tools and the like
provide a secure grasp only through friction with the hand, which
increases with grip force. Thus, extended use or adverse conditions
such as dampness or cold tend to induce fatigue, tremor or loss
of grip in the user. The grip enhancers of the present invention
function by nearly matching the grip surface of the tool or firearm
to the shape and size of the user's hand.
 These and other objects and advantages of the present invention
will become apparent to those familiar with various types of handgrip
accessories for firearms, tools and the like when reviewing the
following detailed description, showing the contemplated novel construction,
combination, and elements as herein described, and more particularly
defined by the appended claims and drawings, it being understood
that changes in the precise embodiments to the disclosed invention
are meant to be included as coming within the scope of the claims,
except insofar as they may be precluded by the prior art. Numerals
are employed to identify corresponding or similar components in
the figures and the description.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
 The following description concerns finger grip enhancers
designed for handgun grips, which are exemplary rather than limiting
of the invention. The finger grip enhancers of the invention can
be designed and installed on the handles, grips or stocks of a wide
variety of hand tools (e.g., garden tools such as rakes, hoes and
shovels and carpentry tools such as hammers, saws and axes), power
tools with pistol grips such as hand drills and saws, sporting implements
(e.g., baseball bats, hockey or lacrosse sticks and the like), firearms
such as pistols (revolvers and "automatics" containing
a magazine within the handle), various long-barreled guns such as
rifles and shotguns, and other projector devices such as crossbows,
archery bows, paintball guns, squirt guns, underwater spearguns
and the like. The long-barreled guns can have conventional stocks
or pistol grips comparable to those used on pistols. The grip enhancers
can also be used on the grips of various mobility aids such as canes,
walking sticks, crutches and the handlegrips of wheelchairs pushed
by attendants. When pulling a loaded wheelchair backwards up an
incline or stairway, it is imperative that the attendant maintain
a secure grip. The grip enhancers can have various suitable sizes,
shapes and configurations, depending upon the shape and size of
the grips which are to be enhanced, the type of tool or firearm
involved, and the size of the user's hands, to mention some principal
factors. The grip enhancers will all generally have the features
or components disclosed and claimed below, however. The grip enhancers
can be produced in assortments of shapes and sizes which can be
selected for use on a variety of tools, weapons and the like. Although
described and illustrated herein primarily as "finger"
grip enhancers, the devices of the invention can be designed or
modified to support or enhance the grip of other portions of the
hand as well. Thus, the devices can be attached to the grip, handle,
frame (including trigger guards and the like), gripping surfaces
or stock of a firearm, for example.
 Although these devices are generally symmetric and are illustrated
and described for use with the right hand, finger grip enhancers
which may be asymmetric can also be constructed for use with left
hand grips, generally by producing mirror images of the embodiments
shown herein. Certain terminology will be used in the following
description for convenience in reference only and should not be
considered limiting. The words "up", "down",
"right" and "left" will designate directions
in the drawings to which reference is made. The words "front"
and "rear" will refer, respectively, to the muzzle end
of a firearm and the opposite end therefrom. The words "top"
and "bottom" will refer to the portions of the components
of the invention and the implements upon which they are employed
which are shown as uppermost or lower in the drawings, and which
are normally uppermost or lower when used in the normal terrestrial
frame of reference in which the "top" or upper surface
is the side opposite the gravitational force.
 The grip enhancers of the present invention, whether used
singly or in combination, are designed and installed to have ergonomic
effects upon the tool grips. "Ergonomic" devices are generally
expected to be safer and/or more efficient when operated by humans.
In particular, the present grip enhancers are expected to make the
user's grip upon the tool or firearm to which they are applied more
stable and secure, without allowing the hand(s) to tire excessively.
See U.S. Pat. No. 4930181 which is incorporated herein by reference,
for descriptions of two ways in which the human hand can grasp a
tool grip and the effects of fatigue when non-ergonomic grips are
 The grip enhancers of the present invention can be installed
and modified to fit not only the fingers, which provides support
from the finger structure of bones and flesh in the areas between
the fingers, but can also be useful in providing a more comfortable,
stronger and less strenuous grasp for the other areas of the hand.
The web of the hand can be protected from the impact of the handgun
slide or hammer by placing a grip enhancer below the hammer or slide
on the back strap. The devices can also be useful when affixed to
the bottom rear surface of the grip safety of military-style Colt
M1911A1 semiautomatic pistols. Many users have difficulty actuating
this safety because their hands are not sufficiently bulky to depress
the lever; the devices of the present invention can add sufficient
bulk, as is done with custom grip safeties which add a bump of metal
to this location.
 The grip enhancers of the present invention can also be
installed or modified for use in improving contact with the shooter's
palm when applied to the side grip panel areas of a handgun. Such
effects are currently accomplished by using custom oversized grips,
which often have to be fitted to the hand using woodworking tools.
The grip enhancers of the invention, particularly when molded of
soft plastic materials, can be easily trimmed and shaped using commonly
available implements such as knives and files. The grip enhancers
of the invention can also be used as finger rests by installation
with the knob portion in a substantially horizontal position to
provide both positioning and support for the trigger finger or thumb.
Such use can be especially useful on revolvers to prevent the cylinder
release from striking the thumb in recoil. Also with revolvers,
modified versions of the grip enhancers can be used to provide more
positive actuation of the hammer to a single action position by
thumb cocking; slippage of the thumb off the hammer during thumb
cocking can cause an accidental discharge of the gun.
 Turning now to the drawings, in FIG. 1 a perspective view
of a plurality of the subject finger grip enhancers is shown, the
grip enhancers having general reference numeral 10. One of the grip
enhancers 10 is mounted on the front of a trigger guard 12 of a
handgun 14. Also, a pair of grip enhancers 10 are shown mounted
on the front and along the length of a grip 16 of the handgun 14.
Clearly, any number of grip enhancers 10 can be used on the grip
of a firearm or tool depending on the size of the user's hand, the
length of the grip, the type of grip application and the other types
of gripping surfaces.
 In FIGS. 2 and 3 both rear and front perspective views
of the finger grip enhancer 10 are illustrated. The grip enhancer
10 includes a finger grip body 18 having a top 20 a bottom 22 and
a flat back surface 24. The flat back surface 24 is generally used
for receiving an adhesive and attaching the grip enhancer to a selected
location on the firearm or a grip of a hand tool. However, threaded
connectors such as setscrews, pressure-fitted pins and other mechanical
connection means, including fabric hook-and-loop fasteners, can
also be used (not shown here). When the grip enhancers are to be
installed on metallic magazine-type handgrips or other metallic
surfaces, the grip enhancers can be made of ferromagnetic materials
which provide sufficient magnetic attraction to hold the grip enhancers
in place. The grip enhancer 10 can be made of a flexible or rigid
plastic, metal material or the like, preferably having a high coefficient
of friction for an improved gripping surface. Magnetic grip enhancers
can be formed of magnetized ferromagnetic metals or polymeric composites
filled with sufficient ferromagnetic particles to produce the same
effect. Many suitable types of polymeric materials are available,
with properties ranging from rigid and brittle to flexible or resilient.
Natural materials comprising wood, ivory and mother-of-pearl can
also be used. It is convenient for the grip enhancers to be molded
or otherwise formed of material which is soft enough to be trimmed
to the optimum size and shape. Materials can be used which absorb
perspiration, as disclosed in U.S. Pat. No. 4785495 which is
incorporated herein by reference.
 The finger grip body 18 also includes an ergonomic shaped
front finger surface 26 having a top portion 28 tapered downwardly
and outwardly into a lower knob portion 30. The lower knob portion
30 is designed to rest against the bottom of a finger and prevent
slippage thereon. The finger or fingers of the user of the finger
grip enhancer 10 are not shown in the drawings.
 In FIGS. 4 and 5 both front and rear perspective views
of another finger grip enhancer 10 are illustrated. In this embodiment,
the grip enhancer 10 has a curved (concave) back surface 32 contoured
for securing the grip enhancer 10 to a curved (convex) portion of
the handgun or hand tool. Obviously, when a rigid material is used
for the grip enhancer, the curved back surface 32 provides for ease
in mounting to a curved portion of the trigger guard 12 as shown
in FIG. 1 and other curved surfaces on a firearm or hand tool.
The backs of the grip enhancers will generally be curved in a concave
manner to fit convex portions of the grips or other portions of
the tools, but can also be designed with convex curved portions
to fit into concavely-curved portions of a tool if necessary.
 The method of installation of one or more grip enhancers
on a tool or firearm grip will generally encompass trial positioning
upon the tool, followed by gluing or attachment by other suitable
means when the appropriate positions have been confirmed. For example,
the grip enhancers can be installed upon a magazine-handled pistol
as illustrated in FIG. 1 using the following steps:
 1) Decide on how permanent the installation is intended
to be. Generally, the stronger the adhesive used, the more likely
the surface (especially polished or blued metal surfaces) is to
be damaged by removal of the grip enhancers and adhesive. For example,
LocTite(R) Black Max(R) is very permanent, and reports are mixed
on whether removal of such adhesive will damage the blueing on firearms.
Epoxy cements will generally damage most finishes. An adhesive which
has been successfully tested for removal without damage to metal
finishes such as anodizing is SuperGlue Corp.(R) Future Glue(R),
but any adhesive should be tested on an inconspicuous area of the
surface before actual use. When installing the grip enhancers on
various polymeric surfaces, most commercial "instant"
glues should be effective.
 2) By trial and error, determine the exact location and
feel desired for each grip enhancer and mark location. Trim the
narrow upper portion of the grip enhancer to a suitable length and
width if necessary.
 3) Apply adhesive to the grip enhancer(s), position carefully
at location for installation and press into position until adhesive
sets, using clamps, rubber bands or the like if necessary.
 4) Inspect final installation to ensure that the resulting
grip is comfortable and effective, and that none of the installed
components block any moving parts of the weapon.
 Installation and testing of the grip enhancers of the present
invention on various handguns including both "automatics"
and revolvers and long-barreled guns including rifles and shotguns
have revealed various advantages. The grip can be custom fitted
for an individual user's hand, providing a firmer grip with less
fatigue in use. When used with pistols, for example, use of the
grip enhancers can make the gun point better, recover faster after
firing and provide a comfortable grip even when used for prolonged
periods. A non-slip grip is provided for all sorts of weather and
atmospheric conditions, whether using one or both hands. (The non-trigger
hand is often used to grasp a handgun, with at least one finger
resting on the grip enhancer which is placed on the trigger guard.)
When used on certain automatic pisols, the grip enhancers of the
invention can prevent "hammer bite," i.e. the impact of
the slide or back of the hammer upon the web of the hand between
the index finger and thumb. This painful effect not only degrades
marksmanship but can lead to irritation and even serious infections
of the hand. To alleviate this, the grip enhancers of the invention
can installed with the lower and knob portions of the devices serving
as a top knob when positioned under the tang of the pistol below
the hammer. In such applications, the knob of the device forces
the flesh of the shooter's hand to the side and rearward, thus keeping
it out of the impact area of the slide and/or hammer.
 Prior art literature acknowledges the need to accommodate
various hand sizes in firearm grips. The grip enhancers of the present
invention not only accommodate different sizes of grips, but allow
the owner to optimize the grip of the firearm or other tool to his
particular hand. In preferred embodiments, single "finger swells"
can be trimmed to length to allow, for example, the bottom surface
of a firearm trigger guard, to provide an upper snug contact surface
with the shooter's middle finger by installation of the device below
the middle finger and as close as comfortable to the guard. Additional
devices can be installed to provide similar support to the bottom
of the shooter's ring finger for an optimum grip. If the pistol
grip is sufficiently long, a third grip enhancer can be installed
below the first two to provide support to the bottom side of the
shooter's little finger.
 The invention will be further illustrated by the following
non-limiting example. One of the grip enhancers were installed on
the grip of a 16 oz. Kel-Tec 9 mm semiautomatic pistol as illustrated
in FIG. 1. Normally, when firing a powerful or very small handgun,
the recoil forces cause an upward movement of the gun and a rotational
torque on the hand. Actual test firing of this weapon before and
after modification according to the invention resulted in substantially
faster recovery times for second shots with precise sight alignment
for the modified version. The shooter also found the modifications
improved the natural pointability of the gun. Firearms trainers
agree that the fit or feel of a pistol in the hand has a substantial
impact upon the shooter's ability to perform rapid point shooting,
such as firing from the hip. A substantial number of firearms experts
and trainers have reported that the feel and pointability of this
modified pistol were notably improved when a single grip enhancer
was installed in an "average" user position. They agreed
that when the devices were installed to optimize the grip for a
particular shooter's hand, the benefits would be increased.
 From reviewing the above-mentioned drawings and specifications,
it is apparent that the finger grip enhancer 10 may have various
geometric shapes and sizes for mounting on firearms, tool grips
and the like without departing from the spirit and scope of the
 While the invention has been particularly shown, described
and illustrated in detail with reference to the preferred embodiments,
it should be understood by those skilled in the art that the foregoing
and other modifications are exemplary only, and that equivalent
changes in form and detail may be made therein without departing
from the true spirit and scope of the invention as claimed except
as precluded by the prior art. The terms and expressions employed
are used as terms of description, not of limitation, and there is
no intention to exclude any equivalents of the features shown and
described, or portions thereof, by using these terms and expressions.
