Description
[0001] This application claims foreign priority benefits from
Canadian Patent Application 2,631,979 filed May 13, 2008.
FIELD OF THE INVENTION
[0002] The present invention relates to an adapter device arranged
to couple an auxiliary stock on a handgun, and more particularly
relates to an adapter device in which a plurality of auxiliary
stocks can be interchangeably supported on a handgun by the adapter
device.
BACKGROUND
[0003] There are various disadvantages to handguns as compared to
rifles as outlined in U.S. Pat. No. 6,318,014 belonging to Porter,
U.S. Pat. No. 6,367,187 belonging to Bubits and U.S. Pat. No.
5,778,588 belonging to Allen, III et al. The prior art patents in
each instance disclose a stock including a shoulder portion for
abutting a shoulder of a user which can be mounted directly onto
the receiver body of a handgun to improve the control of the
handgun. The shoulder portion of the stock and the mounts for
attachment directly to the body of the gun are formed as an
integral component in each instance so that if a different size or
shape of stock is desired, the user must replace the entire device
including the mounts for attachment to the handgun requiring
awkward connection and disconnection to the handgun each time the
stock is to be interchanged.
SUMMARY OF THE INVENTION
[0004] According to one aspect of the invention there is provided
an adapter device for coupling an auxiliary stock to a handgun, the
device comprising: a mounting frame arranged to be mounted onto a
body of the handgun; and a stock mount arranged to support the
auxiliary stock on the mounting frame.
[0005] By providing an adapter which readily permits an existing
stock to be mounted onto a mounting frame which is in turn
supported on the body of a handgun, a universal mount can be
provided on a handgun which allows several different configurations
of stocks to be mounted onto a given handgun without requiring any
replacement or tedious mounting and removal directly onto the gun
body. Accordingly multiple different configurations of stocks can
be mounted to a single handgun at a lower cost and with much less
difficulty in mounting as plural stocks can be mounted to a common
universal frame which can be only fixed to the gun body at one time
each time it is desired to use the handgun with a stock. The
mounting frame remains readily separable from the gun body however
if no stock is desired to be used with the handgun. The mounting
frame further permits a universal mounting configuration for the
stock so that a user can attach existing stocks from various types
of rifles which are already commercially available and have many
interchangeable parts which can be quickly connected and reused
conveniently and at low cost.
[0006] The stock mount is preferably arranged to support the
auxiliary stock thereon such that the auxiliary stock is
selectively separable from the mounting frame.
[0007] There may be provided a stock mounting member supported on
the stock mount which is arranged to support a commercially
available stock thereon such that the stock is selectively
separable from the stock mounting member.
[0008] The stock mount may comprise a threaded socket arranged for
threadably receiving a commercially available stock mounting member
therein. There may also be provided a lock aperture in the stock
mount having an opening lying generally in a common plane with an
opening of the socket at a location spaced radially outward from
the socket. The socket is preferably supported on the mounting
frame so as to be arranged to be spaced rearwardly from a rearmost
portion of the handgun. The socket may be supported by the mounting
frame so as to be arranged to be positioned below a slide of the
handgun or to be near in elevation to a barrel of the handgun.
[0009] Alternatively, the stock mount may comprise an integral
stock mounting member arranged to directly support commercially
available stocks interchangeably thereon.
[0010] The mounting frame may be arranged to: be supported within a
back strap channel of the handgun; be supported on an overhang of a
grip of the handgun; be fastened through a body of the handgun; be
supported on a front accessory mounting rail of the handgun; and/or
receive and clamp a portion of the handgun body therein.
[0011] In some of the illustrated embodiments, the mounting frame
comprises two side plates arranged to span along opposing sides of
the body of the handgun and extend rearwardly beyond a slide of the
handgun in a rearward most position thereof.
[0012] The top side of the gun may be unobstructed by the frame, or
there may be provided a top connected between the sides overtop of
the gun in a generally U-shaped configuration.
[0013] When the sides overlap a majority of the sides of the
handgun, there is provided an opening in the frame arranged to
receive spent casings from the handgun threrethrough and preferably
at least one opening in the frame arranged for receiving a charging
handle of the handgun therethrough.
[0014] There may be provided an accessory mounting rail supported
on top of the mounting frame which is arranged to support
commercially available rifle accessories thereon.
[0015] The mounting frame may further include an accessory mounting
rail arranged to be supported below a barrel of the handgun which
is also arranged to support commercially available gun accessories
thereon.
[0016] In further embodiments, the stock mount may be arranged to
be pivoted relative to the mounting frame such that the auxiliary
stock is arranged to be folded relative to the handgun, and/or
there may be provided one or more attachment locations on the
mounting frame in which the attachment locations are arranged to
support one or more magazines thereon which correspond to the
handgun upon which the mounting frame is arranged to be
mounted.
[0017] Several embodiments of the invention will now be described

DETAILED DESCRIPTION
[0030] Referring to the accompanying figures there is illustrated a
handgun stock adapter device generally indicated by reference
numeral 10. The adapter device 10 is particularly suited for
coupling an auxiliary stock 12 to a handgun 14.
[0031] The adapter device generally comprises a mounting frame 16
which is arranged to be mounted onto a receiver body of the handgun
and a stock mount mounted on the mounting frame which is arranged
to support the auxiliary stock 12 thereon.
[0032] According to the illustrated embodiments described herein,
the device 10 permits commercially available auxiliary stocks 12 to
be mounted to a handgun in which the stocks each comprise a body
extending in a longitudinal direction between a shoulder brace 20
at one end and a mounting sleeve 22 at the opposing end. The sleeve
22 is typically elongate in the longitudinal direction extending
from an open end which is suited for receiving a commercially
available stock mounting member 24 slidably therein.
[0033] The stock mounting member 24 is commonly known as a buffer
tube or a receiver extension. The stock mounting member 24 which is
best suited for use with the present invention comprises an
elongate round tube which is arranged to be slidably received into
the sleeve 22 on the stocks 12 at one end of the tube and which
includes a threaded end 26 opposite the stock which is arranged to
be mounted on the stock mount 18 of the adapter device. A mating
keyway and key may be provided on the sleeve of the stock and the
tube of the stock mounting member respectively. Sliding the stock
mounting member into the stock 12 typically permits the overall
length of the assembled stock 12 to be adjusted relative to the
stock mount 18 by selecting the degree of insertion of the stock
mounting member into the sleeve of the stock for securement at any
one of a plurality of mounting apertures axially spaced along the
mounting member for cooperation with a suitable retaining member on
the stock.
[0034] A lock ring 28 is typically provided at the threaded end 26
of the stock mounting member which includes an aperture 30 therein
which closely receives the threaded end of the stock mounting
member therein. An offset portion 32 of the lock ring is offset
radially outward relative to the aperture. A key formed on the
periphery of the aperture 30 mates with a keyway extending in a
longitudinal direction along the stock mounting member at the
threaded end 26 for resisting relative rotation of the lock ring 28
about the stock mounting member. A protrusion 34 is typically
formed on the offset portion of the long ring for locking
engagement with a firearm upon which the stock mounting member is
mounted when mounting onto an M16 rifle receiver body for example.
A backing nut is typically secured against the locking ring to
secure the locking ring in positive engagement with a firearm upon
which the stock is mounted.
[0035] The mounting frame 16 of the adapter device 10 is typically
suited for mounting onto a handgun of the type comprising a
receiver body 40 having a barrel extending in a longitudinal
direction along the top side thereof from a front end 42 to a rear
end 44 of the body. A hand grip 46 extends downwardly from a rear
end of the barrel which typically includes a hollow area for
receiving a magazine of bullets therethrough. The grip 46 also
includes a rear overhang 48 at the upper portion thereof which
extends rearwardly to overhang the lower portion of the grip.
[0036] The grip also includes a back strap channel 50 which extends
upwardly through the grip along the rear side thereof typically for
mounting various accessories onto the receiver body of the handgun.
The handgun typically also includes a slide 52 mounted along a top
side of the barrel for sliding movement in the longitudinal
direction of the barrel relative to the receiver body 40 so as to
be displaced rearwardly beyond the grip in a retracted position for
loading a casing into the barrel of the gun. Some handguns further
comprise an accessory mounting rail 54 on the receiver body 40
which extends along a bottom side of the barrel adjacent the front
end of the gun. A charging handle 56 may be mounted to extend
laterally outward from either side of the slide 52 at the rear end
thereof to manually displace the slide relative to the receiver
body of the gun.
[0037] Additional components of the handgun may comprise a trigger
pin 58 extending through the receiver body adjacent the trigger, a
locking block pin 59 extending through the body above the trigger
pin, a slide release 60 at one side of the gun body for releasing
the slide, and a takedown lever 62 accessible at both sides of the
gun for taking apart the components of the handgun.
[0038] Though various embodiments of the adapter device 10 are
described and illustrated in the following, the common feature of
the illustrated embodiments will first be described herein. The
mounting frame 16 in each instance is arranged to secure to one or
a combination of the following components of the handgun including:
the back strap channel 50, the overhang 48 on the rear grip, the
trigger pin 58 or other pins in the body of the gun, the front
mounting rail 54, or any other fixed component of the receiver body
onto which the mounting frame may be clamped. In each instance the
mounting frame is arranged to allow free movement of the slide 52
relative to the receiver body. Furthermore in each instance, the
stock mount 18 is supported by the mounting frame at a position
spaced rearwardly from both the receiver body 40 and the slide in
its rearmost retracted position relative to the receiver body.
[0039] As illustrated the stock mount comprises a socket 64
arranged to threadably receive the threaded end 26 of a
commercially available stock mounting member 24 as described above,
for example a stock mounting member of the type which is used to
secure an auxiliary stock to the receiver body of an M16 rifle or
other similar firearm. The commercially available stock mounting
member in turn permits various configurations of commercially
available stocks 12 to be supported thereon for in turn supporting
the stocks on the receiver body of the handgun.
[0040] The socket 64 is internally threaded and generally
cylindrical about an axis which is oriented parallel to the
longitudinal direction of the barrel of the handgun upon which the
mounting frame is supported. Spaced radially outward from the
socket 64 there is provided a lock aperture 66 which is positioned
relative to the socket 64 so as to be arranged for mating
connection with the protrusion 34 on the lock ring 28 when a lock
ring is also provided on the threaded end 26 of the stock mounting
member received within the socket 64 of the device 10.
[0041] In alternative embodiments, the stock mount 18 on the
mounting frame 16 of the adapter device 10 may comprise an
integrally supported stock mounting member having one end which is
configured similarly to commercially available stock mounting
members so that the integrally supported stock mounting member on
the mounting frame still permits commercially available stocks 12
to be readily mounted in a releasable manner onto the mounting
frame which is supported on the handgun.
[0042] Accordingly in either configuration of the stock mount 18 of
the adapter device, that is either an integrally formed stock
mounting member or a socket which receives a commercially available
stock mounting member, the adapter device 10 according to the
present invention permits stock members 12 of various
configurations to be quickly and easily mounted in a readily
releasable manner onto the body of a handgun. Also in either
configuration, the stock mounting member is arranged to be
positioned spaced rearwardly from the slide of the gun in the
rearmost position, either at the same elevation as the barrel or
spaced slightly therebelow.
[0043] Turning now to the embodiment of FIGS. 1 through 6 and the
embodiment of FIGS. 7 and 8, the adapter device 10 is shown to
comprise a mounting frame 16 which extends the full length of the
gun body from the front end to the rear end as well as extending
rearwardly beyond the rear end of the handgun for supporting the
stock mount on the rear end of the frame at a location which is
spaced rearwardly from the slide of the handgun in its rearmost
position. In each instance the frame 16 generally comprises a pair
of side plates 70 which are parallel to one another to extend
generally in the longitudinal direction along opposing sides of the
body 40 of the gun. The plates 70 are arranged to be fixedly
mounted relative to the receiver body of the gun with sufficient
lateral clearance being provided between the side plates and the
slide of the gun so as not to interfere with movement of the slide
relative to the receiver body of the handgun.
[0044] A clamp is provided in the form of two clamping members 72
supported between the side plates 70 adjacent the front end thereof
so as to be arranged to be fastened together by a suitable fastener
extending through both side plates and the two clamping members
which function to clamp the two side members onto opposing sides of
the receiver body 40 and more particularly the mounting rail 54
below the barrel at the front end of the body. The frame also
includes a lower portion 74 which is fixed between the two side
plates 70 to maintain the side plates at a fixed spacing on
opposing sides of the slide of the handgun. The lower portion 74 is
coupled between lower front edges of the two side plates for
containing the clamping members 72 thereabove for mounting on the
mounting rail 54 of the receiver body. An auxiliary mounting rail
76 is provided on the lower portion 74 of the frame to be oriented
in the longitudinal direction of the gun upon which the device is
supported at a location directly below the exiting mounting rail 54
on the gun body.
[0045] When supported on a glock pistol as shown in the
accompanying figures, the side plates include a depending portion
at the location of the trigger pin 58 and the locking block pin 59
so that replacement pins can be inserted between the two side
plates through the receiver body of the handgun at the location of
the trigger pin 58 and the locking block pin 59 to provide
additional securement of the frame to the body of the handgun.
[0046] To further secure the mounting frame to the gun body, a
retainer bar 78 may also be provided for attachment between the two
side plates of the mounting frame at the rear end thereof below the
overhang 48 of the grip of the handgun. A fastener is provided for
extending through the retainer bar 78 and both side plates at
opposing ends of the bar for securing the retainer bar at a
preferred location in engagement with the rear of the gun body.
Slots 80 are provided in the two side plates which extend in the
longitudinal direction for receiving the fastener of the retainer
bar 78 therethrough so that the retainer bar can be coupled between
the two side plates at one of a plurality of longitudinally spaced
positions for accommodating different lengths of handguns secured
between the clamping members at the front end of the mounting frame
and the retainer bar 78 at the rear end.
[0047] A bottom edge of each of the side plates is arranged to be
suitably located relative to the retainer bar and the clamping
members so that when the frame is mounted on the receiver body of
the handgun, access remains to various components of the handgun
including the slide release 60 and the takedown lever 62.
[0048] Turning now more particularly to the embodiment of FIGS. 1
through 6, the mounting frame is shown with a top plate 82 which is
connected between the two side plates along the length of the frame
so that the frame has a generally inverted U-shape in cross
section. The top plate 82 is supported by the side plates to be
spaced above the slide of the handgun so as not to interfere with
operation of the slide. The top plate 82 serves to mount an
auxiliary mounting rail 84 extending along the length of the
receiver body of the handgun for mounting various configurations of
commercially available accessories including rifle scopes and the
like. When extending the side plates upwardly to support a top
plate 82 therebetween, cut outs 86 are provided in the form of
openings in the side plates in alignment with an ejector of spent
casings on the handgun on one side and the charging handle access
on both sides at the rear of the frame.
[0049] Turning now to the embodiment of FIG. 7 and 8, the side
plates of the frame may instead terminate at a top edge which is
arranged to be mounted at a location spaced below the top side of
the slide of the handgun as well as being below the charging handle
and the casing ejector on the handgun so that no additional cut
outs are required in the sides.
[0050] According to the first and second embodiments in FIGS. 1
through 8, the mounting frame is secured to the handgun receiver
body by inserting the front end of the body between the clamping
members at the front end of the frame for subsequent clamping using
the provided fasteners. Replacement pins may be provided for
securement through the trigger pin location and/or locking block
pin location above the trigger of the handgun for additional
securement. The retainer bar 78 is also fastened in place in snug
abutment against the rear side of the grip below the overhang. In
each instance of the first and second embodiments, the stock mount
18 is positioned at the same elevation as the barrel spaced
rearwardly beyond the rear end of the gun body and beyond the rear
end of the slide in a rearmost position. A commercially available
stock mounting member 24 is threaded into the socket of the stock
mount and secured using the lock ring and backing nut by aligning
the protrusion of the lock ring within the stock mount as the
aperture in the stock mount and the socket receiving the threaded
end of the stock mounting member 24 have an opening in a common
rear plane of the stock mounting 18.
[0051] Turning now to FIGS. 9 and 10, a further embodiment of the
adapter device is illustrated in which the mounting frame 16 is
supported on the body of the handgun primarily by being received
within the back strap channel 50 extending up through a rear side
of the grip 46 of the handgun. Accordingly the mounting frame 16
includes a stem portion 88 which is suitably sized for fitting
within the back strap channel. The stem portion is accordingly
generally elongate with a tapering cross section for mating
connection within the back strap channel of the handgun. A locking
protrusion 90 may be provided adjacent a base of the stem position
88 for interlocking engagement with a respective mounting hole
located within the grip of the handgun to selectively retain the
stem portion 88 of the mounting frame received within the back
strap channel of the handgun.
[0052] The mounting frame 16 in the embodiment of FIGS. 9 and 10
further comprises a central portion 92 which extends generally
rearwardly in the longitudinal direction of the handgun from the
bottom end of the stem portion when the stem portion is received
within the back strap channel. A rear portion 94 of the mounting
frame extends upwardly from a rear end of the central portion at a
distance sufficiently spaced from the stem portion to comfortably
accommodate a hand of a user about the grip of the handgun without
interference by the rear portion 94 of the mounting frame. The rear
portion extends upwardly to an upper end supporting the stock mount
18 thereon to similarly face rearwardly away from the handgun at a
location spaced rearwardly from the handgun in a mounted position.
The stock mount 18 as illustrated in FIGS. 9 and 10 is
substantially identical to the previous embodiments for
accommodating commercially available stock mounting members
threadeably received therein so that various forms of commercially
available stocks can be mounted onto the handgun by the mounting
frame and stock mount. The stock mount 18 is arranged to be
supported near in elevation to an upper free end of the stem
portion so as to be spaced below the slide of the handgun when the
stem portion is received within the back strap channel.
[0053] Turning now to FIGS. 11 and 12, a fourth embodiment of the
adapter device is shown which includes all of the features of the
previous embodiment in FIGS. 9 and 10 along with the additional
feature of an auxiliary support portion 96 on the mounting frame to
be connected to an auxiliary mounting point on the handgun body in
addition to the stem portion received in the back strap channel of
the grip. In the illustrated embodiment the auxiliary support
portion 96 includes a first portion 98 extending upwardly and
forwardly from the stock mount generally towards the stem portion
in the longitudinal direction, and a second portion 100 which
extends forwardly from the first portion 98 generally horizontally
so as to be generally parallel and spaced above the central portion
92 at the bottom of the mounting frame. A forward end of the second
portion 100 comprises a coupling element 102 which is arranged to
grip the overhang 48 of the grip of the handgun to provide
additional support between the stock mount and the receiver body of
the handgun. The coupling element is arranged to be attached to the
gun body at a location below the slide so as not to interfere with
movement of the slide relative to the gun body.
[0054] In use, according to the third and fourth embodiments, the
stem portion of the mounting frame is first inserted into the back
strap channel such that the protrusion 90 on the stem portion mates
with the mounting hole in the grip of the handgun to retain the
mounting frame mounted on the gun body. Optionally, the auxiliary
support portion 96 may be provided for securement to an additional
location on the gun body. A stock mounting member can then be
attached to the stock mount 18 as described above in previous
embodiments for supporting a commercially available auxiliary stock
18 thereon. The stock mounting member 24 permits various types of
stocks, including commercially available stocks to be readily
interchanged with one another while the mounting frame can remain
secured to the handgun body.
[0055] In yet further embodiments, the adapter device 10 may
include a hinge between the mounting frame 16 and the stock mount
18 so that a stock supported on the stock mount can be folded
relative to the handgun upon which the mounting frame is mounted
for collapsing the overall size of the assembled handgun and stock
for storage as may be desired. The hinge may pivot about either a
vertical or a horizontal axis.
[0056] In yet further embodiments the mounting frame 16 may be
provided with a plurality of attachment points, at longitudinally
spaced positions thereon between connection of the mounting frame
on the body of the handgun and the stock mount 18, which are
suitably arranged to secure additional magazines thereon of the
type which are received within the grip of the corresponding
handgun upon which the mounting frame 16 is mounted.
[0057] Since various modifications can be made in my invention as
herein above described, and many apparently widely different
embodiments of same made within the spirit and scope of the claims
without department from such spirit and scope, it is intended that
all matter contained in the accompanying specification shall be
interpreted as illustrative only and not in a limiting sense.
