Description
BACKGROUND OF THE INVENTION
This invention relates to improved pistol grip structures to be
connected to the handle of a pistol in a relation presenting
resiliently deformable external surfaces of elastomeric material
for contact with the hand of a person using the gun, in a relation
maximizing comfort to the hand and reducing the transmission of
recoil from the gun to the user.
The present grip is in some respects similar to the type of grip
shown in U.S. Pat. No. 3,672,084 issued June 27, 1972. In that
patent there has been shown a grip structure including a pair of
similar molded rubber body sections received at opposite sides of
the handle of a pistol and interengaged in a central plane of the
grip, with reinforcing plates received in the two sections.
SUMMARY OF THE INVENTION
The present invention provides an arrangement in which essentially
a single unitary grip unit is adapted to be connected to the handle
of a pistol in a manner such that the single unit serves to provide
resilient surfaces of elastomeric material at both sides of the
handle and extending across the front thereof, to by itself
effectively cushion the contact between the gun and a person's hand
at all of these locations. Of particular importance is the manner
in which this single unit very positively retains in position the
portion of the grip which extends across the front of the pistol
handle, without the necessity for any fasteners at that location.
The manner of retention of this forward portion of the grip is such
as to enable that portion to be made very thin if desired, to thus
provide a continuous elastomeric surface at the front of the handle
without requiring the provision of an excessively thick piece of
material at that location which might interfere with optimum
gripping of the gun.
Structurally, the grip of the present invention has two opposite
side portions of elastomeric material, desirably an appropriate
fairly soft rubber, adapted to be received at the opposite sides
respectively of the pistol handle and containing essentially rigid
reinforcing plates embedded in and stiffening these two side
portions, with the elastomeric material also forming a forward
portion of the grip extending between and interconnecting and
formed integrally with the two side portions and adapted to extend
across the front of the pistol handle. The two side sections are
adapted to be secured in position at opposite sides of the handle,
and by such retention will in turn effectively hold in proper
position the forward portion of the grip which is received at the
front of the handle. The reinforcing plates in the side portions
enable those side portions to have sufficient rigidity to serve
their intended purpose even though the elastomeric material itself
may be fairly soft, to maximize the cushioning action. The side
portion may be retained in place by screws extending through
openings in those side portions and connecting to the gun handle.
Preferably, threaded projections carried by the opposite sides of
the handle extend into these openings, in a relation accurately
locating the side portions of the grip relative to the gun handle.
The reinforcing plates in the elastomeric side portions may contain
apertures for contacting or essentially contacting the projections
on the gun handle, and may have shoulders engageable by the
retaining screws to positively position the entire grip very
accurately and in predetermined manner on the pistol handle.
Each of the reinforcing plates in the side portions of the grip
unit is desirably curved essentially arcuately about a generally
vertical axis, and between two opposite side edges of the plate,
with the plate preferably reducing gradually in width as it
advances upwardly along the side of the handle, and with the plate
preferably having inturned top and bottom ears or flanges at its
upper and lower extremities.

DESCRIPTION OF THE PREFERRED EMBODIMENT
While it is to be understood that certain features of the invention
can be applied to grips for any of various different types of
pistols, I have typically illustrated at 10 in FIG. 1 and others of
the figures a gun of the `Colt` type, having a downwardly
projecting hollow handle 11 to which a grip unit 12 embodying the
invention is attached. The handle contains the usual ammunition
clip 13 (FIG. 3), which is insertable upwardly into the interior of
the handle from its lower end, to feed a series of rounds
successively to the chamber 14 of the gun for firing. A trigger 15
controls firing operation of the hammer 16, which is automatically
cocked by recoiling movement of a slide 17.
As seen in FIGS. 2 through 6, the handle 11 of the pistol has two
parallel essentially planar vertically extending opposite side
walls 18 and 19, having oppositely facing outer planar parallel
vertical surfaces 20 and 21. At the front of the handle, the two
side walls 18 and 19 are connected together by a forward portion 22
of the rigid handle 11, which may be externally curved or rounded
as seen in FIGS. 5 and 6. Each of the side walls 18 and 19 of the
gun handle carries two upper and lower outwardly projecting
locating bosses 23 and 24, which are externally cylindrical about
horizontal axes 25 and 26 extending perpendicular to planar
opposite side surfaces 20 and 21 of the handle. These bosses
contain internal threads 27 for connection to screws 28 to be
utilized in securing the grip 12 on the gun.
The grip unit itself may be considered as including two opposite
side sections 29 and 30, to be received at opposite sides of handle
11 as shown, and interconnected by a forward portion 31 of the grip
which extends across the front of forward wall 22 of the gun
handle. As will be best understood by reference to FIGS. 8 and 9,
all three of these sections or portions 29, 30 and 31 of the grip
are molded integrally as a single body of elastomeric material,
desirably a fairly soft neoprene or other rubber having a shore
hardness between about 35 and 55, with two rigid preferably metal
reinforcing plates 32 and 33 being embedded within and bonded
continuously to the side portions 29 and 30 respectively. The two
side sections 29 and 30 have inner planar surfaces 34 and 35 which
abut against the outer planar surfaces 20 and 21 respectively
formed at the opposite sides of the gun handle, with bosses or lugs
23 and 24 received and fitting closely within two apertures 36 and
37 in each of the side sections of the grip unit, in a relation
very accurately locating the side sections relative to the rigid
handle of the gun.
The rubber of the grip may be initially molded in the flattened
condition of FIG. 9, in which the central or forward portion 31 of
the grip unit may have a planar surface 38 extending between and
forming a continuation of the two aligned previously mentioned flat
surfaces 34 and 35. When the grip is attached to the gun, this
surface 38 of portion 31 is held tightly against and curves in
correspondence with the forward curving surface of portion 22 of
the handle, as seen in FIGS. 5 and 6. This portion 31 desirably has
a thickness t which is much less than the maximum thickness T of
the two side portions.
As seen in FIGS. 4, 5, 6, 11 and 12, each of the reinforcing plates
is curved arcuately about a generally vertical axis, in extending
between two edges 43 and 44 of the plate, with the radius of
curvature desirably decreasing slightly as the plate 32 or 33
advances upwardly. Further, the front to rear dimension of each
plate, between its edges 43 and 44, desirably decreases gradually
in an upward direction. Edges 43 and 44 are just slightly embedded
within the rubber, and are located essentially within a plane 47
which is spaced only slightly from and parallel to the plane of the
corresponding surface 34 or 35. At its upper end, the material of
each of the plates 32 or 33 is turned inwardly as seen in FIG. 11
to form a flange or tab 48 whose edge 49 lies essentially in the
same plane 47 as do edges 43 and 44. Similarly, at the bottom of
each plate 32 or 33, an inturned tab or flange 50 is formed having
an edge 51 desirably lying again in the same plane 47.
The rubber of each of the side sections 32 or 33 is molded to
present an outer arcuately curved surface 52, which curves in
correspondence with and is essentially parallel to and spaced
outwardly a short distance from the outer arcuately curved surface
53 of the reinforcing plate 32 or 33. Each surface 52 extends
between and is defined by two front and rear edges 41 and 42 which
are closely proximate to and essentially parallel to edges 43 and
44 of the reinforcing plates. Like plates 32 and 33, surfaces 52
preferably decrease gradually in radius of curvature, and in front
to rear width w between edges 41 and 42, as they advance upwardly
from their lower ends 39 to their upper ends 40. Plates 32 and 33
may have a series of cutaway regions 45 along edges 43 and 44, and
a series of spaced openings 46, for assuring an effective bonding
of the rubber body to each of the plates.
Surfaces 52, as well as the outer surface 54 of the forward or
intermediate portion 31 of the grip unit, are all provided with
"checkering" or other irregularities 55, to facilitate effective
grasping of the gun handle in use. A non-checkered protrusion 155
may be provided on each of the side sections if desired, as shown,
to better fit the contour of the user's thumb and fingers at the
level of the trigger.
The openings 36 and 37 within which bosses or lugs 23 and 24 on the
gun handle are received extend through both the rubber and metal of
the side sections 32 and 33, and are circular and a close fit about
the corresponding circular lugs 23 and 24, to thus positively
locate the side portions of the grip unit relative to the gun by
actual metal to metal contact of the reinforcing plates with lugs
23 and 24. As best seen in FIG. 3a, the screws 28 have enlarged
heads at their outer ends which are just slightly larger than the
openings 36 and 37 in the metal reinforcing plates 32 and 33, so
that when the screws are tightened they engage inwardly against the
metal of the reinforcing plates about openings 36 and 37, to thus
tightly clamp the plates inwardly in a manner retaining the side
sections of the grip unit against the opposite sides of the handle.
The reinforcing plates 32 and 33 may also have a pair of inwardly
necked essentially tubular portions 56 which can be engaged by
locating pins in a molding die during the molding of the rubber
body of the grip unit, to thereby assure proper positioning of the
reinforcing plates within the rubber, with the peripheral edges of
the plates preferably being completely enclosed within the rubber
at all locations.
In mounting the grip unit 12 to a gun, one of the side sections 32
or 33 may first be positioned adjacent its respective side of the
gun handle, with two of the lugs or bosses 23 and 24 received in
locating relation within the openings 36 and 37 of that section.
Two of the screws 28 may then be tightened into their respective
bosses 23 and 24, to tightly clamp that first side section against
the gun handle. The forward portion 31 of the grip unit is then
pulled across the front of the gun handle, following which the
second side section may be positioned at the second side of the gun
handle, with the second pair of lugs 23 and 24 received in the
second set of apertures 36 and 37. In order to position this second
pair of lugs within their corresponding apertures 36 and 37, the
forward portion 31 of the grip must be pulled tightly against the
front of the gun handle. The application of the final pair of
screws to the second side of the handle retains the entire assembly
in place. In using the gun, a person's hand engages and grasps the
checkered surfaces of the two side portions 32 and 33 of the grip,
and of the forward portion 31, with the soft rubber providing a
very effective cushioning action at all of these locations, to
increase the comfort and effectiveness of the grip and cushion the
recoil, while the reinforcing plates maintain the soft rubber
against excessive deformation.
Though a certain embodiment of the present invention has been
disclosed as typical, the invention is of course not limited to
this particular form, but rather is applicable broadly to all such
variations as fall within the scope of the appended claims.
