Sling for a shoulder weapon
Abstract
A sling for a shoulder weapon, such as a military assault rifle
or carbine, in which the effective length of the sling can be
extended quickly and quietly and then easily and quietly retracted
to the original length. A quick release plate and an engagement
member cooperate to hold a loop of strap material to provide the
shorter configuration of the sling, and the quick release plate can
be manipulated easily to pass over the engagement member to
lengthen the sling. A latching mechanism can be released quickly to
disconnect a portion of the sling in an emergency. The opposite
ends of the sling can be attached to or disconnected from a weapon
easily and quickly using secure, quiet fittings.

Description
RELATED APPLICATIONS
[0001] This application is a continuation-in-part of pending U.S.
patent application Ser. No. 10/392,463, filed Mar. 18, 2003, now
U.S. Pat. No. ______.
BACKGROUND OF THE INVENTION
[0002] The present invention relates to slings for shoulder
weapons, and particularly for military tactical weapons.
[0003] It is usually desirable to use a sling to carry a military
shoulder weapon so it is quickly available and ready for use while
leaving a soldier's hands free for performing other tasks when the
weapon is not actually in use.
[0004] Many military rifle slings have been known in the past, and
some of them have been designed to be lengthened readily from a
length best adapted for carrying the weapon to a length best for
using the weapon while in a particular position. Usually, a sling
permits a weapon to be raised to a soldier's preferred shoulder.
Depending on the locality of a target with respect to a structure
behind which a soldier can be partially concealed, however, in some
cases it is necessary for a soldier to shoot with the weapon at his
opposite, non-preferred shoulder. Preferably, the soldier should be
able to move the weapon to the non-preferred shoulder without
having to disengage the sling from his body, but to do so may
require that the sling be lengthened.
[0005] Some previously available slings for shoulder weapons have
been configured for a three point attachment, with a first or inner
strap portion extending along one side or the other of the weapon
from its buttstock to its forestock. A second, or outer, strap
portion that passes around the soldier's body, usually over one
shoulder, is fastened to the first strap near the forestock of the
weapon, but with its front end releasable to slide rearward along
the first strap to give the soldier the additional freedom required
to raise the weapon to the non-preferred shoulder. In such slings
the second strap portion of the sling, when released to slide along
the inner strap, moves so as to surround the body of the soldier
more closely, increasing the difficulty of removing the weapon
quickly should that be required. Also, previously available devices
for releasing and reengaging the sliding end of the second strap
have been less than desirably easy to operate, particularly for a
soldier wearing gloves.
[0006] When soldiers are to be transported by motor vehicle, it may
be preferable to detach slings from their tactical weapons to avoid
entanglement of the slings that would make quick use of the weapons
difficult upon rapid exit from the vehicle, or might interfere with
quickly emerging from the vehicle.
[0007] Many previously available arrangements for attaching the
rear end of a sling to a rifle buttstock have been cumbersome and
complicated, and take more time than is desired for disconnection
and reconnection. Also, many previously used sling and connectors
have been undesirably noisy.
[0008] One previously available sling is a tactical weapons sling
available from Safety Systems Corporation of Hanover Park, Ill.
That sling includes an enlargement at one point along a first or
inner sling strap, and a quick release plate is ordinarily held by
sling strap tension in an orientation in which the quick release
plate cannot move along the inner sling strap past the
enlargement.
[0009] A carbine sling available from Boonie Packer Products
division of JFS, Inc. of Salem, Oreg., utilizes a piece of flexible
strapping which becomes doubled-over and jams behind a slide to
keep a front end of a sling strap in the usual configuration. The
doubled loop of strapping must be pulled forward from the slide to
release the movable front end to slide along the inner sling strap,
but this requires a significant pull toward the front end of the
weapon, causing a slight delay before the sliding front end of the
sling can be moved rearwardly along the inner sling strap.
[0010] It is desired, then, to have a sling that is easily and
quickly lengthened when desirable, that is easily disconnected to
permit removal from around a person's body, and that is easily
detachable from and reattached to a weapon.
SUMMARY OF THE INVENTION
[0011] The present invention overcomes the aforementioned
shortcomings of previously available slings for military shoulder
weapons by providing a sling of which a portion is in the form of a
strap extending through a strap slide aperture and then doubling
back along its own length for at least some distance to a position
where its traveling end is held releasably by engagement of a quick
release plate with an engagement member attached to a main portion
of the strap. The quick release plate is normally held generally
parallel with the main portion of the strap by tension in the
sling. Reorientation of the quick release plate to a position
generally perpendicular to the main portion of the sling allows a
part of the engagement member to flex and thus release the quick
release plate from the engagement member, allowing the quick
release plate to slide along the sling strap toward the strap slide
aperture and allowing the doubled portion of the sling strap to
move through and then away from the slide aperture, thus increasing
the effective length of the sling.
[0012] In one preferred embodiment of the invention, the engagement
member is a length of webbing material attached to the main portion
of the sling strap with a flexible free end tab directed away from
the doubled portion of the sling strap.
[0013] As another aspect of the invention, a mounting loop for
fastening an end of a sling to a shoulder weapon includes a
non-slipping fastening arrangement.
[0014] As yet a further aspect of the present invention, an
emergency release latching device permits a portion of the sling to
be detached quickly from an intermediate part of the sling so that
the sling can be removed quickly from around a person's body.
[0015] The foregoing and other objectives, features and advantages
of the invention will be more readily understood upon consideration
of the following detailed description of the preferred embodiments

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0045] Referring now to the drawings which form a part of the
disclosure herein, in FIG. 1 a military shoulder weapon, in this
case an automatic rifle 22, is carried by a soldier, supported by a
sling 24 attached to the automatic rifle 22 and arranged to extend
from the buttstock 26 over the soldier's right shoulder, around his
back, and to the forestock 28, supporting the automatic rifle 22 in
a high carry position which enables a right-handed soldier to raise
the automatic rifle 22 quickly to his right shoulder and there to
grip the pistol grip 30 with his right hand and support the
forestock 28 with his left hand. A person using such a sling can
thus raise the automatic rifle 22 quickly to his preferred shoulder
in the usual shooting position while the sling 24 remains in its
normal configuration arranged to support the automatic rifle 22 in
the high carry position. A buttstock sling mounting loop assembly
32 includes a short attachment strap 34 to which a D-ring 36 is
fastened to receive the rear end 38 of the sling 24. The rear end
38 of the sling 24 is thus attached to the right side of the
buttstock 26, holding it close to the soldier's chest, as shown in
FIG. 1.
[0046] A front attachment loop assembly 40 attaches the front end
42 of the sling 24 to the forestock 28 of the automatic rifle 22. A
quick release plate 44 may be utilized as will be explained
presently to extend the length of the sling 24 quickly and silently
to an increased length.
[0047] In FIG. 2, the automatic rifle 22 is shown as it would be
carried by a right-handed soldier, in a horizontal carry position,
with the sling 24 extending from the buttstock 26, passing under
the soldier's right arm, around his back, and down over his left
shoulder to the forestock 28. The quick release plate 44 is further
from the front attachment loop assembly 40 than its position as
shown in FIG. 1, as will be explained in greater detail presently.
The extended length of the sling 24 is great enough to permit the
automatic rifle to be raised easily to either shoulder.
[0048] In some situations, it becomes desirable for a soldier to
shoot a shoulder weapon such as the automatic rifle 22 from his
non-preferred shoulder. Thus, in FIG. 3, a soldier is holding the
automatic rifle 22 to his left shoulder, although the sling 24 is
arranged to extend from the buttstock 26 over the soldier's right
shoulder as shown in FIG. 1, where the automatic rifle 22 is
supported in the high carry position used by a right-handed
shooter.
[0049] The sling 24, used in its ordinary configuration for a high
carry as shown in FIG. 1, is too short to permit the buttstock 26
to be placed readily at a right handed shooter's left shoulder as
shown in FIG. 3. However, the length of the sling 24 can quickly
and quietly be extended to that shown in FIG. 2, to permit a
right-handed soldier to quickly place the automatic rifle on his
left shoulder as shown in FIG. 3 in order, for example, to shoot
around the left end of a protecting wall without exposing his body
completely beyond the wall.
[0050] Referring to FIGS. 4 and 5, the sling 24 is shown shortened
by omission of parts of the longer strap portions, in order to more
clearly illustrate the way in which its parts are interconnected.
At the rear end 38, an elongate rear strap portion 46 may be of a
suitable flexible webbing such as a well-known flat, nylon webbing
that is about 1 inch wide and 0.08 inch thick. A front end of the
rear strap portion 46 is sewn or otherwise fastened to form a loop
48 engaging the curved side of a pair of plastic D-rings 50. The
D-rings 50 are provided as a pair to ensure ample strength for
unusual situations although one is sufficient for normal loads. The
rear strap portion 46 extends rearwardly from the D-rings 50
through a fastener such as a metal tribar slide 52 to form an
elongate rear end adjustable loop 54. The rear end adjustable loop
54 passes through a connector such as a pair of loops 53 which are
part of a sling attachment stopper device 55 that will be explained
subsequently. The adjustable loop 54 permits the overall length of
the sling 24 to be adjusted to fit the particular weapon and
soldier and to accommodate possible different ways of attaching the
rear end 38 of the sling 24 to the buttstock of a weapon, or of
attaching the front end 42 of the sling 24 to a forward portion of
a weapon.
[0051] Extension of the Sling
[0052] Extending forward from the D-rings 50 is an elongate quickly
extendible front strap portion 56 of the sling 24. The front strap
portion 56 may be of webbing material similar to that of the rear
strap portion 46 and is held by a metal front tribar slide 58 or
other suitable fastener to form an adjustable fastening loop 60 by
which the front end 42 of the sling 24 may be attached to the front
attachment loop assembly 40 or otherwise fastened to the forward
portion of a weapon such as the automatic rifle 22.
[0053] A main portion 62 of the quickly extendible front strap
portion 56 extends rearwardly from the front end 42 which is fixed
to the forward part of a weapon, and passes through the D-rings 50.
The opening within the D-rings 50 acts as a strap slide aperture 64
through which the front strap portion 56 can slide easily around
the straight side of the D-rings 50.
[0054] An extension portion 66 of the extendible front strap
portion 56 is doubled back toward the front end 42, alongside the
main portion 62, and has a traveling end 68 fastened to a quick
release plate 70, as by being sewn to form a loop. It will be
understood that the traveling end 68 of the extension portion of
the strap could be fastened to the quick release plate 70 by other
means, as by being molded into a quick release plate 70 of suitable
plastic construction. In the present embodiment, however, a readily
available tribar slide of molded plastic construction is used as
the quick release plate 70, and the traveling end 68 is fastened to
one of the side bars of the tribar slide, as shown in FIGS. 4 and
5.
[0055] The quick release plate 70 defines a slot 72, between its
center bar and the side bar to which the traveling end 68 of the
front strap portion 56 is attached, and the main portion 62 extends
through the slot 72 alongside the loop in the traveling end 68, on
a side of the front strap portion 56 which ordinarily faces toward
the forestock of a weapon, such as the automatic rifle 22, to which
the sling 24 is connected.
[0056] On an opposite or outer side 74 of the extendible front
strap portion 56, an engagement member 76 is securely attached to
the main portion 62. The engagement member 76 has a flexible free
front flap portion 78 that extends away from the strap slide
aperture 64 and toward the front end 42 of the sling 24. The
engagement member 76 is of strong resiliently flexible material,
and may preferably be of a tightly woven flat webbing material
thinner than the webbing material of the front strap portion 56 but
less easily flexible. The webbing is doubled back on itself to
provide a loop acting as the front flap 78, although such a loop is
not necessary, and the engagement member 76 could be made of
another material if desired, so long as it is not excessively
flexible. The engagement member 76 is securely fastened to the main
portion 62, as by being sewn thereto.
[0057] As may also be seen in FIGS. 6 and 7, a front portion 79 of
the quick release plate 70 adjacent the slot 72 rests between the
front flap 78 and the outer side 74 of the main portion 62 of the
strap. When the sling 24 is in use, with tension in the extension
portion 66 and the main portion 62, the quick release plate 70 lies
alongside and generally parallel with the main portion 62 in which
it causes a small bend, as shown in FIG. 7. The front flap 78 is
thus on one side of the front portion 79 of the quick release plate
70, while the outer side 74 of the main portion 62 is on the other
side, and the engagement member 76 thus prevents the quick release
plate 70 from moving along the main portion 62 away from the front
end 42 of the sling 24. The width 80 of the slot 72 is small enough
that tension in the extension part 66 keeps the quick release plate
70 oriented generally parallel with the main portion 62, with
relatively little force directed toward the front flap 78, so that
movement of the quick release plate 70 along the main portion 62 is
effectively resisted by the engagement member 76.
[0058] The front strap portion 56 of the sling 24 can be quickly
extended in length, however, by releasing the quick release plate
70 from engagement with the engagement member 76. This is
accomplished by grasping the front portion 79 of the quick release
plate and moving it from closely alongside the main portion 62 to a
position approaching perpendicularity with the main portion 62, as
shown in FIG. 8. This movement of the quick release plate 70
presents the slot 72 more widely open toward the front flap 78, so
the quick release plate 70 can flex the front flap 78 toward the
attached portion of the engagement member 76 and thus toward the
strap slide aperture 64 in the D-rings 50. This allows the quick
release plate 70 to move along the main portion 62 away from the
front end 42 and toward the strap slide aperture 64, with the
extension portion 66 then sliding through the strap slide aperture
64 of the D-rings 50 to increase the effective length of the
quickly extendible front strap portion 56. The length of the
extension portion 66 is effectively added to the length of the main
portion 62 by allowing the quick release plate 70 to slide back to
the D-rings 50. The front portion 79 of the quick release plate 70
can easily be grasped by a soldier, even when wearing gloves, to
rotate it to the position shown in FIG. 8 and thus allow the
quickly extendible front strap portion 56 to be extended.
[0059] In order to restore the length of the sling 24 to the
shorter ordinary configuration allowing the automatic rifle 22 to
be carried in the high carry position shown in FIG. 1, it is
necessary to move the traveling end 68 and the quick release plate
70 along the extension portion 66 of the strap, pulling it back
through the strap slide aperture 64, and then along the main
portion 62 to the engagement member 76, in the direction indicated
by the arrow 82 in FIG. 9. When the slot 72 of the quick release
plate 70 has been moved past the entire engagement member 76,
including the front flap 78, tension applied to the quick release
plate 70 through the traveling end 68 of the extension portion 66
can draw the quick release plate 70 once more into the position
shown in FIG. 7, to retain the traveling end 68 of the extension
portion 66 adjacent the engagement member 76, with the sling thus
in its shorter ordinary length configuration.
[0060] Alternative Sling
[0061] A sling 86 shown in FIGS. 10 and 11 is an alternative to the
sling 24 and may be of the same materials and include similar
components, but is arranged slightly differently. At a rear end 87
of the sling 86, a rear strap portion 88 has its rear end fashioned
into an adjustable loop 90 held by a tribar slide 92 corresponding
with the tribar slide 52 of the sling 24. The adjustable loop 90
extends through linking loops 94 of a sling attachment stopper
device 55, although it could otherwise be engaged with a buttstock
of a weapon with which the sling 86 is to be used.
[0062] A quickly extendible front strap portion 98 of the sling 86
is similar to the quickly extendible front strap portion 56 in the
sling 24, but is oriented in the opposite direction. A fixed first
end of its main portion 100 thus is an integral extension of the
rear strap portion 88, and an engagement member 76 has its front
flap 78 directed toward the rear strap portion 88. The main portion
100 extends forward from the rear strap portion 88 toward the front
end 104 of the sling 86, and passes slidably through a strap slide
aperture 106 defined by a pair of D-rings 108 which may be similar
to the D-rings 50. An extension portion 110 doubles back along the
main portion 100 toward the rear strap portion 88, along the inner
side of the main portion 100, the side that faces toward the weapon
when the sling 86 is in place. As in the sling 24, the engagement
member 76 is located on the opposite, outer side 112 of the main
portion 100, facing away from a weapon on which the sling 86 is
installed. A traveling end 114 of the extension portion 110 is
attached securely to a quick release plate 116 which may be
identical to the quick release plate 70 described with respect to
the sling 24.
[0063] Operation of the quickly extendible front strap portion 98
to extend the length of the sling 86 is the same as that described
above with respect to the sling 24 and shown in FIGS. 7, 8, and 9,
except that extension of the sling 86 is accomplished by releasing
the quick release plate 116 to move forward from the engagement
member 76 toward the front end 104 of the sling 86.
[0064] A short front end sling mounting strap 118 has its free end
adjustably and releasably held by a tribar slide 120, forming an
adjustable fastening loop 121 to permit attachment of the front end
104 of the sling 86 to a forward portion of a weapon. The other end
of the front end sling mounting strap 118 is fastened securely to
the curved side of the pair of D-rings 108, as by being sewn to
itself in the form of a loop 122, to support the D-rings 108 so
that the quickly extendible front strap portion 98 can slide freely
through the strap slide aperture 106 and around the straight side
of the D-rings 108.
[0065] Front End Attachment
[0066] As shown in FIGS. 6, 12, and 13, the front end 42 of the
sling 24 is attached to the forestock 28 by engagement of the
adjustable loop 60 in a sling receiving aperture 124 defined by the
front end attachment loop assembly 40. The front end attachment
loop assembly 40 includes a first, or outer, flexible elongate
tension carrying member such as a strap portion 126 whose opposite
ends are interconnected with each other by a releasable and
adjustable fastener such as a tribar slide 128, so that the strap
member 126 fits snugly about the forestock 28 or other forward part
of a weapon to which the sling 24 or sling 86 is to be attached. A
small bight 130 of the outer elongate flexible strap 126 extends
through the eye of a sling swivel 132, where it is held in place by
a slotted stopper plate 134 through whose slots the outer strap 126
extends, to keep the front end attachment loop assembly 40 in a
desired position with respect to the sling swivel 132. The stopper
plate 134 is small enough to pass through the eye of the sling
swivel 132 lengthwise, but once subjected to tension in the outer
strap 126, the stopper plate 134 aligns itself with the sling
swivel and holds the bight 130 within the eye of the sling swivel
132, while the outer strap 126 is held by the tribar slide 128. An
inner strap member 136 extends along a part of the outer strap 126,
between it and the forestock 28. The inner strap 136 is attached to
the outer strap 126 at two locations spaced apart by a great enough
distance to define a sling receiving aperture 124 with a preferred
length in the range of one inch to two inches, to receive and hold
the strap 126. The position of the outer strap 126 in the stopper
plate 134 can be adjusted to place the aperture 124 at either side
of the forestock 28, as shown in FIGS. 6 and 13, or to adjust it
further toward the top of the forestock 28 if desired.
[0067] The inner strap 136 preferably extends beyond the aperture
124 and is fastened to the outer strap 126 to form a similar second
strap receiving aperture 125. This arrangement may be particularly
useful for a shoulder weapon having a sling swivel on a side of its
forestock rather than the bottom of its barrel. With a bight 130 of
the strap 126 attached to such a sling swivel the aperture 124
could then be on the top of the forestock and the aperture 125
would be about 180.degree. away around the forestock, opposite the
sling swivel. Thus the sling 24 could be advantageously used by a
soldier preferring to carry and shoot a right-handed weapon
left-handedly.
[0068] In one preferred embodiment of the attachment loop assembly
40, the outer strap 126 may be of a tubular webbing material, such
as a readily available one-half inch wide tubular nylon webbing,
and a ribbon 138 of a strong heat-resistant material, such as a
half inch wide woven tape of Kevlar polyamide aramid fabric, is
preferably housed as a core within the webbing material. Such a
material is desired as a core within the outer strap 126 in order
to preserve the integrity of the connection of the sling 24 to the
forestock of a military weapon which may become so hot with
continued firing of the weapon that a front attachment loop
assembly 40 made of a material with a low melting point might fail
just when it is most needed. While the problem of high temperature
has been answered in the past by use of metal sling fittings, such
fittings often rattle with a sound which might easily be heard by
an adversary, while the front attachment loop assembly 40, since it
is of largely fabric construction, provides a nearly silent
attachment of a sling to a weapon.
[0069] A sling attachment device 144 for military weapons which do
not include a sling swivel at their forward ends is shown in FIG.
14. The loop 60 at the front end 42 of the sling 24, or the loop
121 at the front end 104 of the sling 86, can be fastened around a
pair of D-rings 142 included in the sling attachment device 144, in
which an elongate flexible tension carrying member, such as a cord
or narrow strap 146, has at least one end 148 securely fastened to
a D-ring or a pair of D-rings 142 so that the strap 146 can be used
to fasten the D-ring or D-rings 142 to a desired part of a weapon.
Like the strap 126 of the attachment loop assembly 40, the strap
146 preferably has a core 149 of a strong heat-resistant material
such as Kevlar polyamide aramid.
[0070] Preferably, both of the opposite ends 148 of the strap 146
are securely fastened to the D-rings 142, so that the strap 146
forms a loop which can be hitched securely around the desired part
of a weapon to which a sling is to be attached, such as the
vertical front part 150 of a front sight of the automatic rifle 22.
In order to avoid unnecessary and undesirable noise caused by the
connection of the sling to a weapon, a silencing hood 152 is
provided around the D-rings 142, attached, for example, to the
strap 146. Preferably, the silencing hood 152 is a short,
thin-walled tube of a soft or resiliently flexible material capable
of absorbing an impact and deadening the sound that would otherwise
be made. For example, a short length of thin-walled rubber tubing
material similar to bicycle tire inner tube material is
satisfactory as the silencing hood 152, although leather or fabric
could also be used. At the end of the tube opposite its attachment
to the strap 146, an open mouth 154 permits the adjustable sling
strap loop 60 to be inserted and threaded through the D-rings 142
to attach the sling 24 to the attachment device 144.
[0071] Rear End Attachment
[0072] The sling 24 is attached to the buttstock 26 of the
automatic rifle 22, as shown in FIGS. 1, 15, and 16, by the
buttstock sling mounting loop assembly 32. The buttstock sling
mounting loop assembly 32 includes a stock-encircling strap 158.
Preferably the stock-encircling strap 158 is of tightly woven flat
webbing of synthetic material such as a non-elastic nylon so that
it is not readily stretched.
[0073] A first end portion of the stock-encircling strap 158
defines a loop 160 fastened about the middle bars of at least one,
and preferably a pair of tribar slides 162, which may be of sheet
metal and are held stacked together by the loop 160 extending
through a pair of parallel slots between the middle and outer bars
of the tribar slides 162. While the pair of tribar slides 162 has
shown superior performance, a single tribar slide 162 may also
prove to be satisfactory. The loop 160 is preferably formed by
stitching through the material of the strap 158. The loop 160 lies
along a first face of the pair of tribar slides 162, between them
and the buttstock 26.
[0074] A stopper plate 164 similar to the stopper plate 134 is
fitted onto the strap 158 about three to five inches away from the
loop 160, with a bight 166 of the strap 158 extending through the
eye of a rear sling swivel 170, where it is held in place by the
stopper plate 164. A slide loop, and preferably a pair of rigid,
generally rectangular slide loops 168, of a molded high strength
plastic material, encircle the doubled portion of the first end of
the strap 158 adjacent to the stacked tribar slides 162.
[0075] The strap 158 extends from the slide loop or loops 168
downward along the side of the buttstock 26 to the sling swivel
170, and then up and along the opposite side of the buttstock 26 to
its top. After passing around the top of the buttstock 26, an upper
portion 171 of the strap 158 extends along and into the pair of
stacked slides 162 on their first face from the direction opposite
the loop 160. The upper portion 171 passes through the tribar
slides 162, as seen best in FIG. 16. The tribar slides 162 thus
fasten together the first end of the strap 158 and the upper
portion 171 of the strap 158. The strap 158 continues from the
tribar slide or stacked tribar slides 162 through the slide loops
168, and a D-ring 172 is attached securely to a free second end
part 174 of the strap 158, as by a loop sewn into it.
[0076] The stopper plate 164 in the bight 166 engaged in the rear
sling swivel 170 holds the buttstock attachment loop 32 in a
desired position on the buttstock 26. Tension in the free end part
174, when it acts through and on the slide loops 168, tends to
tighten the engagement of the tribar slide or slides 162 on the
strap 158, as the slide loop or loops 168 are urged along the first
end portion of the strap member 158 toward and against the stacked
tribar slides 162 by tension in the free end portion 174. The
downwardly extending upper portion 171 of the strap 158 is thus
pulled through the stacked tribar slides 162, tightening the
stock-encircling strap 158 around the buttstock 26. When the free
end portion 174 is allowed to become slack, the stacked slides 162
act as a buckle and secure the strap 158 around the buttstock 26,
maintaining tension in the upper portion 171. By selectively
orienting the bight 166 within the eye of the sling swivel 170, the
loop 160 and attached tribar slides 162 can be placed on either
side of the buttstock 26, as desired.
[0077] The adjustable loop 54 of the rear strap portion 46 of the
sling 24 or the adjustable loops 90 of the rear strap portion 88 of
the sling 86 can be attached directly to the D-ring 172, by
disengaging an end of the strap from the respective tribar slide 52
or 92 and refastening it with the strap extending through the
D-ring 172. Alternatively, a stopper assembly 55 can be attached
similarly to the rear strap portion 46 or rear strap portion 88 by
engaging the rear strap portion through a loop or pair of loops 53
included in the stopper assembly 55.
[0078] Sling Mounting Stopper
[0079] In one preferred embodiment, as shown in FIG. 15, the
stopper device 55 includes a short strap 182 of suitable webbing
material, such as that of the sling straps 46 and 88, attached to
the middle bar of a stopper plate in the form of a tribar slide 184
which may be of sheet metal. The strap 182 is also looped through
and around one side of the plastic loops 53, attaching the loops 53
to the tribar slide 184, by a length of doubled strap 182
separating it from the loops 53 by a distance 186 of, for example,
about 3 inches, although the distance 186 is not critical.
Preferably, the loops 53 are held more closely than the tribar
slide 184, which preferably has some freedom to move and for the
loop of strap material 182 to which it is attached to be flexed and
move about the middle bar of the tribar slide 184 to equalize the
stresses in the opposite sides of the loop engaging the middle
bar.
[0080] A flexible securing tab 188 of ribbon-like webbing material,
such as a tightly woven non-stretch nylon webbing material about as
wide as the strap 182, is fastened as a small loop 190 encircling a
side bar 192 of the tribar slide 184. The short end 194 of the
webbing material forming one side of the loop 190 extends through
the slot between the side bar 192 and the middle bar of the tribar
slide. The short end portion 194 lies closely along and in contact
with the portion of the strap 182 that passes around the middle bar
of the tribar slide 184, when the free end 196 extends through a
slot 198 between the middle bar and the side bar opposite the side
bar 192, as shown most clearly in FIG. 15. The short end portion
194 thus causes the securing tab 188 to form a considerable hump
above the portion of the strap 182 that passes around the middle
bar of the tribar slide 184, as shown in FIGS. 5 and 11, when the
free end 196 is pulled tight through the slot 198 to the side of
the tribar slide 184 from which the strap 182 extends toward the
loops 53.
[0081] As shown in FIG. 16, when the free end 196 of the securing
tab 188 is free from the slot 198, the securing tab 188 may be
pulled away from the strap 182 to make the tribar slide 184 lie
closely alongside the doubled part of the strap 182 leading toward
the loops 53. The combined thickness of the doubled strap 182 and
the tribar slide 184 is small enough that the tribar slide 184 and
the strap 182 can be pulled through a relatively narrow slot, with
the tribar slide 184 in an edgewise orientation, leaving the loops
53 on one side of the material defining the slot while the tribar
slide 184 is on the opposite side. Thereafter, when the free end
196 extends through the slot 198 the securing tab 188 is pulled
snugly around the middle bar of the tribar slide 184, the
combination acts as a stopper plate and is too thick to pass
through such a narrow slot. Additionally, when the loop 190 or the
free end 196 encounters a surface of the object, such as the D-ring
172, defining the slot or opening through which the strap 182
extends, the tribar slide 184 is urged into apposition as shown in
FIG. 11 in which its major plane is oriented transverse to the
portion of the strap 182 that extends away from the middle bar of
the tribar slide 184, further preventing the stopper from passing
back through the slot or opening in the opposite direction.
[0082] Such a stopper assembly 55 could be used at either or both
of the ends 38 and 42 of the sling 24 or the ends 87 and 104 of the
sling 86, to attach the sling 24 or 86 to a front attachment loop
40, attachment device 144, or a buttstock sling mounting loop
32.
[0083] The stopper assembly 55 is particularly useful, as shown in
FIG. 17, for attaching a sling 24 to the buttstock 202 of a
military carbine. The buttstock 202, instead of having the
traditional shape of a wooden buttstock, includes a tubular portion
204 and a flat web 206 extending downward from the tubular portion
204 and defining a slot 208, in which a stopper assembly 55 is
engaged to attach a sling 24 to the carbine.
[0084] Alternative Rear End Attachment
[0085] An alternative mounting loop assembly 210 for fastening a
sling 24 or the like to a buttstock 26 of a shoulder weapon
includes a stock-encircling strap 212, preferably of closely woven
fabric such as a strong non-stretch nylon webbing, whose opposite
ends define respective loops 214 and 216 facing each other and
separated by a small distance 218 when the mounting loop assembly
is in place on a buttstock 26 of a shoulder weapon. A small bight
220 of the strap 212 extends through the sling swivel 170, where it
is held in place by a slotted stopper plate 222 mounted on the
strap 212.
[0086] A fastener assembly interconnecting the loops 214 and 216
adjustably with each other includes a first end piece in the form
of a bar 224 extending through the first loop 214 and a second
piece in the form of a generally U-shaped member 226 engaged in the
second loop 216. A pair of screws 228 are engaged rotatably in
respective through-bores 230 defined near the ends of the bar 224
and parallel with each other. The screws 228 are engaged in mating
threads in the leg portions 232 of the U-shaped member 226. With
the leg portion 232 oriented as shown in FIG. 18, facing toward the
bar 224, the threads of the screws 228 are received within the
threads in the facing leg portions 232, and the screws 228 can be
adjusted to tighten the strap 212 around the buttstock 16. The legs
232 cover the threads and the ends of the screws 228 so that they
are not openly exposed to catch on the surroundings of a weapon on
which the mounting loop assembly 210 is used. The bar 224 and the
U-shaped member 226 are preferably of a strong plastic material in
order to be quieter than metal and not be subject to corrosion.
[0087] The mounting loop assembly can be attached so that the
fastener assembly can be placed on either side of the buttstock 26
by rotation of the bight 220 within the eye of the sling swivel
170, and the position of the strap 212 in the stopper plate 222 can
be adjusted as necessary to place the fastening assembly where
desired.
[0088] On the opposite side of the buttstock 26, a sling strap
receptacle 234 is fastened to the strap 212. The receptacle 234 may
be in the form of a length of tubular webbing doubled over along
itself and forming a slot 236 to receive a strap or to engage a
stopper 55 described above. Preferably, a small rod 238 is retained
within an outer leg of the tubular webbing material to provide a
stable, stiffened shoulder to receive a strap or the stopper plate
184 of a stopper 55. The rod 238 may, for example, be of a hard
plastic material.
[0089] Where the distance 218 between the loops 214 and 218 in
opposite ends of the sling mounting loop assembly 210 is short,
exposing the ends of the screws 228, the orientation of the
U-shaped member 226 may be reversed, and the leg portions 232 of
the U-shaped member 226 may be directed away from the bar 224
engaged in the strap loop 214, as shown in FIG. 20, to provide a
protective covering for the threaded ends of the screws 228 when
they are adjusted to tighten the strap 212 adequately around a
buttstock.
[0090] Alternative Sling
[0091] Referring now to FIGS. 21-28, additional aspects of the
invention are embodied in a sling 250 shown mounted on the
automatic rifle 22. A rear end portion 252 of the sling 250 is
attached to the buttstock 26 by a buttstock attachment loop
assembly 254. The buttstock attachment loop assembly is fastened to
the rear sling swivel 170 of the automatic rifle 22 by a sling
swivel attachment device 256 including a stopper similar to the
stopper device 55 described previously. A quickly detachable sling
end mounting loop assembly 258 interconnects a main strap member
260 of the sling with the buttstock attachment loop assembly 254,
as will be described in greater detail presently. The main strap
member 260 of the sling may be of a conventional suitably strong
synthetic textile webbing of a suitable width, such as 11/4
inch.
[0092] A forestock attachment loop assembly 264 surrounds the
forestock 28 and is shown connected to the front sling swivel 132
of the automatic rifle 22 by a sling swivel attachment unit 266
which is somewhat different from the sling swivel attachment device
256, although a sling swivel attachment device 256 could be used
instead. A front end portion 268 of the sling 250 is interconnected
with the forestock attachment loop assembly 264.
[0093] While the sling 250 is shown with the main strap member 260
on the left side of the automatic rifle it could also be mounted on
the right side, as will be readily apparent, by simply reorienting
various parts. Preferably, the sling 250 is made with components
that will not be unnecessarily noisy in use, as will be understood
from the following description.
[0094] The sling 250 is arranged in a three point sling
configuration, in which a first portion 269 of the main strap
member 260 of the sling extends rearwardly from the front end
portion 268 to the quickly detachable sling end mounting loop
assembly 258 alongside the buttstock 26. A second portion 270 of
the main strap member 260 thence extends forward alongside the
first portion 269. The main strap member 260 in the rear end
portion 252 of the sling 250 extends slidably through a pair of
D-rings 271, 272 that are part of the quickly detachable sling end
mounting loop assembly 258, as shown in FIGS. 25 and 26. An
adjustable loop 274 in the second portion 270 of the main strap
member 260 is formed and held adjustably by a tribar slide 276.
[0095] In FIGS. 21 and 22, the front end portion 268 of the sling
250 is shown attached to the forestock attachment loop assembly 264
by a loop 277 formed in the main strap member 260 and held by a
tribar slide 278. A quickly detachable sling end mounting loop
assembly 258 could instead be interposed between the loop 277 in
the main strap member 260 and the forestock loop assembly 264 to
facilitate more expeditious removal from the automatic rifle
22.
[0096] The loop 274 in the second portion 270 of the main strap
member 260 is connected to an emergency release latching assembly
280 releasably latched to a short connecting section 282, which in
turn is fastened to a quick release plate 284 similar to the quick
release plate 70 described above. The quick release plate 284,
connecting section 272, and latching assembly 280, together with
the forward part of the loop 274, constitute a traveling end
portion 286.
[0097] The traveling end portion 286 is normally held releasably
but securely in a forward position near the front end portion 268
of the sling 250 by engaging the quick release plate 284 with an
engagement member 288 mounted on the main sling strap member 260 a
distance away from the extremity of the front end 268 of the sling
250. The user of the sling 250 may adjust the distance between the
engagement member 288 and the forestock attachment loop assembly
264 by adjusting the loop 277 held by the tribar slide 278.
[0098] The traveling end portion 286 can be released from the front
end portion 268 to move rearwardly along the first portion 269 of
the main strap member 260 by operation of the quick release plate
284 in same manner described above for operation of the quick
release plate 70 and the engagement member 76 in the sling 24, and
that aspect of use of the sling 250 thus need not be described here
in detail.
[0099] Ordinarily, the sling 250 is utilized with the first portion
269 of the main strap member 260 extending alongside the forestock
28, receiver, and buttstock 26 of the automatic rifle 22, and the
forwardly directed second portion 270 of the main strap member 260
may be placed over the user's shoulder in a way similar to the
placement of the sling 24 over the user's shoulder as shown in
FIGS. 1 and 2. When the quick release plate 284 is operated to
release the traveling end portion 286 and allow it to move
rearwardly along the first portion 269 of the main strap member
260, rearward movement of the traveling end portion 286 along the
first portion 269 of the main strap member 260 allows the main
strap member 260 to slide through the D-rings 271, 272 of the sling
end mounting loop assembly 258. The first portion 269 is thus
effectively lengthened between the attachments of the sling 250 to
the forestock 28 and the buttstock 26, allowing the automatic rifle
22 to be moved somewhat more freely, as to be raised to a shooting
position against the non-preferred shoulder.
[0100] Releasing the traveling end 286 to slide rearwardly results
in the first portion 269 being free to move further away from the
side of the forestock 28 and receiver of the weapon, but shortens
the second portion 270, and thus leaves less of the main strap
member 260 between the quick release plate 284 and the buttstock
attachment loop assembly 254 to extend around the user's body. The
rearward part of the first portion 269 of the main strap member
260, the remaining part of the second portion 270, and the
traveling end portion 286 then extend around the body of the user
as a sling loop of reduced circumference.
[0101] In an emergency, it may be desired to remove the automatic
rifle 22 or other weapon or article carried by the sling 250
quickly from the user's body, without having to slide the sling
loop over other equipment being carried on the user's torso. In
such a situation the emergency release latching assembly 280 may be
operated to disconnect the front end of the loop 274 from the first
portion 269 of the main strap member 260.
[0102] For the emergency release latching assembly 280 to operate,
the short connector section 282 may preferably be a short length of
textile webbing similar to that of the main strap member 260,
appropriately secured to the quick release plate, as by sewing to
form a loop 294 disposed around one bar of a tribar slide 284 and
another loop 296 disposed through both of a pair of D-rings 290,
292. The D-rings 290, 292 are preferably non-metallic and may be
readily available D-rings of Delrin.TM. plastic. Use of both of the
D-rings 290, 292 is not essential to operation of the sling or the
emergency release latching assembly 280, but is preferred to ensure
ample strength under unusual circumstances that might be
encountered by a soldier using the sling 250. The first portion 269
of the main strap member 260 also extends through both of the
D-rings 290, 292, so that the short connector section 282 is
normally kept closely alongside the main strap member 260, on the
side of the main strap member 260 opposite the engagement member
288, when the quick release plate 284 is engaged with the
engagement member 288. The normal direction of tension in the short
connecting section 282, resulting from the pull exerted on the
D-rings 290, 292 by the emergency release latching assembly 280,
thus ordinarily prevents unintended disengagement of the quick
release plate 284 from the engagement member 288, even though the
forward part of the loop 274 pulls the emergency release latching
mechanism assembly 280 away from the first portion 269 of the main
strap member 260, rather than lying alongside it, when the sling
250 is in use.
[0103] The emergency release latching assembly 280 includes a pair
of D-rings 298, 300 held in a loop 302 of, for example, one inch
flat tubular webbing material formed and held, as by appropriate
stitching, in a first end of an elongate primary load-carrying
member 304. The D-rings 298, 300 may be similar to the D-rings 290,
292, and while one of the D-rings 298, 300 is sufficient for normal
use of the sling 250, the additional strength provided by both
D-rings 298, 300 is preferred to assure ample strength under
unusual circumstances and may provide an additional benefit by
allowing the loop 274 in the main strap member 260 to bend with a
larger radius of curvature.
[0104] The loop 274 extends slidably through the D-rings 298, 300,
connecting the emergency release latching assembly 280 to the
second portion 270 of the main strap member 260. The elongate
primary load-carrying member 304 extends from the loop 302 to a
flexible hinge portion 306 extending through and around the D-rings
290, 292 on the same side of the main strap member 260 as the
engagement member 288. The D-rings 290, 292 thus act as connector
loops by which the emergency release latching assembly is
interconnected releasably to the short connector section 282 and
thus to the quick release plate 284.
[0105] Attached to the hinge portion 306 and extending alongside
the elongate primary load-carrying member 304 toward the loop 302
is a substantially rigid tongue portion 308. An inner end 310 of
the tongue 308 is interconnected with the hinge portion 306, while
an outer end 312 of the tongue 308 extends toward the loop 302 when
the emergency release latching assembly 280 is fastened in its
normal configuration as shown in FIGS. 22 and 24. In one preferred
embodiment of the emergency release latching assembly 280, the
primary load bearing member 304, the hinge portion 306, and the
tongue portion 308 include respective parts of a continuous length
of suitably strong, flat, tubular woven webbing.
[0106] At least one and preferably a pair of keepers 314 encircle
the primary load bearing member 304 and the tongue 308 to retain
the tongue 308 closely alongside the primary load carrying member
304. The keepers 314 are loops and may, for example, be readily
available molded Delrin.TM. plastic keepers. Preferably, the
keepers 314 are secured to the primary load-carrying member 304 and
kept near the hinge portion 306 by a flexible retainer 316, which
may be an extension of the webbing of the primary load bearing
member 304, fastened, as by being sewn, near the hinge portion
306.
[0107] The tongue 308 is made rigid by a core 318 that may be of
sheet metal or an appropriate synthetic material kept in the
appropriate positions within the tongue portion 308 as by stitching
near the inner end 310 and stitching 322 at the outer end 312 of
the tongue 308. While the stitching near the inner end 310 is
desired merely to keep the core 318 in position within the tongue
308, the outer end 312 must be held securely about the core 318 by
a fastening such as the stitching 322 or another securing device
with ample strength to support a significant amount of the tension
loading carried by the main primary load bearing member 304, since
the flexible material of the hinge portion 306 is pulled around the
D-rings 290, 292 by the primary load bearing member 304 when the
emergency release latching assembly 280 is under tension.
[0108] Preferably the core 318 is of sheet stainless steel, in
order to resist corrosion. Rather than simply being a straight
length of flat sheet stainless steel that will fit within the
tubular webbing material of the tongue 308, the core 318 preferably
is bent to include a lower portion 324 offset far enough to define
an open throat 326 adjacent the hinge portion 306 and between the
tongue 308 and the primary load bearing member 304. The throat 326
receives the D-rings 290, 292, which function as connector loops
through which the short connecting member 282 is connected to the
loop 274 by the latching assembly 280.
[0109] The tongue 308 preferably includes a detent to prevent
unintended removal of the keepers 314 from engagement around the
tongue 308. For example, a raised dome 328 is formed in the core
318 near the outer end 312 of the tongue 308. The dome 328
protrudes away from the primary load-carrying member 304 to retain
the keepers 314 between the dome 328 and the offset portion 324. So
that the emergency release latching assembly 280 will be less
susceptible to wear, an opening 330 is preferably formed in the
tubular textile webbing material of the tongue 308, exposing the
raised dome 328 to be engaged directly by the keepers 314. The
margin of the textile fabric surrounding the opening 330 is
preferably treated to prevent fraying, as, in the case of the
tubular webbing being of Nylon or another synthetic thermoplastic
material, by heating the material defining the margins of the
opening 330 to fuse the fibers together.
[0110] The emergency release latching assembly 280 is released by
moving the keepers 314 in the direction of the arrow 332 to pass
over the raised dome 328 or other detent and thence off the outer
end 312 of the tongue 308. This frees the tongue 308 and allows the
hinge 306 to flex to an extended orientation, with the outer end
312 revolving through an angle about the hinge portion 306 as shown
in FIG. 23 to extend away from the primary load-carrying member
304. The tongue 308 is thus freed to be withdrawn from engagement
with the D-rings 290, 292 and thus be separated from the short
connecting member 282, leaving the second portion 270, including
the loop 274, free to move away from the first portion 269 of the
main strap member 260 and thus away from the automatic rifle 22 or
other object with which the sling 250 is being used, and freeing
the sling from around the user.
[0111] As may be seen in FIGS. 25 and 26, the buttstock attachment
loop assembly 254 includes an elongate stock-encircling strap 334
which may be of suitable woven webbing, for example flat tubular
webbing one inch wide, with a respective toggle member 336, 337
such as a metal tribar slide attached at each of the opposite ends
of the strap 334 by a respective loop formed in a portion of the
strap material extending around the center bar of the particular
tribar slide. An adjustment buckle, such as a tribar slide 338, is
included to permit adjustment of the effective length of the strap
334, so that the buttstock attachment loop assembly can be fitted
tightly to the buttstock 26 to provide a stable attachment of the
sling 350 to the automatic rifle 22. The buttstock attachment loop
assembly 254 is preferably mounted on the buttstock 26 with the
tribar slide 338 facing outwardly away from the buttstock 26, to
prevent unnecessary noise.
[0112] Each of the toggle members 336, 337 is engaged in a
respective one of a pair of D-rings 340, 342 attached to an
elongate main flexible strap 344 of the sling swivel attachment
device 256, which may be of suitable woven webbing. The two D-rings
are attached to the flexible strap 344 facing oppositely away from
each other and at right angles to the length of the flexible strap
344, as by being sewn into loops formed in a short length 345 of
similar strap or webbing material, allowing the D-rings to pivot
toward the stock-encircling strap 334 as shown in FIGS. 25 and 26.
The two D-rings 340, 342 are preferably non-metallic, and
preferably molded plastic D-rings of suitable size and strength
such as Delrin.TM. D-rings for webbing one inch wide, while the
tribar slides 336, 337 are similarly for webbing one inch wide, so
that each tribar slide can be passed through the respective D-ring
340, 342 in a lengthwise direction when the strap 334 is twisted as
shown in FIG. 27. The tribar slides 336, 337, however, then toggle
and engage the D-rings 340, 342 as stoppers and cannot pass through
them when tension is applied to the stock-encircling strap 334 and
brings the tribar slides 336, 337 into alignment as shown in FIG.
25. This manner of connection keeps the metal toggle members 336,
337 from striking the buttstock 26, thus helping keep the sling 350
quiet in use.
[0113] At the end of the stock-encircling strap 334 opposite the
adjustment buckle 338, a sling strap receiving loop 346 is attached
to the stock-encircling strap 334 adjacent to or spaced a
predetermined small distance away from the toggle member 336, so as
to receive the sling strap at the desired position on the buttstock
28.
[0114] A pair of spacers such as molded plastic keepers 348 are
engaged with the sling strap receiving loop 346 and encircle the
stock-encircling strap 334, ensuring that the sling strap receiving
loop 346 remains open to permit attachment of a sling strap when
the stock-encircling strap 334 is fitted tightly around the
buttstock 26 as shown in FIGS. 21 and 25.
[0115] When the stock-encircling strap 334 has been adjusted to a
proper length to fit tightly on the buttstock 28 and has been mated
with the sling swivel attachment device 266, the sling swivel
attachment device 266 is used to attach the entire buttstock
attachment loop assembly 254 to the sling swivel 170. The sling
swivel attachment device 266 has a toggle member, preferably a
metal tribar slide 347 secured in a loop of the strap member 344
around its center bar. A locking tab 349 is preferably a short
length of woven webbing which may be thinner than the webbing
material of the strap 344 and which is fastened to one of the outer
side bars of the tribar slide 347. With the locking tab 349
extending away from the strap member 344 as shown in FIG. 26, the
locking tab can pass through the sling swivel 170 followed by the
tribar slide 347 in a transition position aligned generally
parallel with the strap member 344. Once the tribar slide 347 has
passed through the opening of the sling swivel 170 it can toggle
into a stopper orientation as shown in FIG. 25, at which time the
free end of the locking tab 349 is passed through the slot between
the center bar of the tribar slide 347 and the bar to which the
locking tab is not fastened. With the free end of the locking tab
349 then pulled between the sling swivel 170 and the tribar slide
347 as shown in FIG. 25, the locking tab 349 prevents the toggle
347 from rotating back into a position aligned with the strap
member 344 and presents enough thickness of the layers of the strap
member 344 and the locking tab 349 to prevent the toggle member 347
from passing back through the sling swivel 170. The toggle member
347 and the strap member 344 are of a size small enough to pass
through the opening of the sling swivel 170 without having to be
twisted to an endwise orientation such as that of the
stock-encircling strap 334 and its toggle member 336 illustrated in
FIG. 27, and the length of the strap member 334 thus need only be
long enough to permit the toggle member 347 to pass through the
sling swivel 170 and toggle into its locking orientation as shown
in FIG. 25.
[0116] As mentioned above, the main strap member 260 of the sling
250 is attached to the buttstock attachment loop assembly 254 by a
quickly detachable sling end mounting loop assembly 258, which
includes an elongate tension bearing strap member 350 such as a
length of flexible webbing one inch wide, for example, having
opposite first and second ends and having a length sufficient to
fit through the sling strap receiving loop 346 and around the
stock-encircling strap 334 when secured in position as shown in
FIGS. 21 and 25. A loop 352 such as a molded plastic D-ring is
carried on the first end of the tension bearing member 350, held
securely in place as by a loop sewn or otherwise fastened in the
material of the first end of the tension bearing member 350. A
toggle element 354 such as a metal tribar slide is mounted at the
opposite, second end of the tension bearing member 350 and has a
size related to that of the loop 352 so that the toggle element can
be passed through the loop in an endwise orientation, but cannot
pass through the loop when the tension bearing member 350 is under
tension and orients the toggle element 354 to act as a stopper as
shown in FIG. 25.
[0117] A strap receiving ring and preferably a pair of similar
strap receiving rings, such as the D-rings 271, 272 large enough to
hold the main strap member 260, are mounted on the intermediate
portion of the tension bearing member 350 and face away from the
buttstock 26 and forward with respect to the automatic rifle 22
when the sling end mounting loop assembly 258 is engaged with the
buttstock attachment loop assembly 254. Preferably the pair of
D-rings 271, 272 are mounted on the intermediate portion of the
tension bearing member 350 and held in a desired position with
respect to the tension bearing member 350 by a flexible retainer
360 such as a short length of ribbon-like fabric of suitable
strength and of a width similar to or slightly less than that of
the tension bearing member 350 and whose ends may be sewn to the
tension bearing member 350 at spaced-apart locations. Preferably, a
stabilizer such as a tribar slide 362 is located between the
strap-receiving rings, with the tension bearing member 350
extending through one slot of the tribar slide and the retainer
member 360 extending through the other slot of the tribar slide
362, so that the tribar slide substantially prevents the tension
bearing member 350 of the sling mounting connector 258 from
becoming twisted.
[0118] The toggle 354 is free to move to a connecting-disconnecting
position aligned substantially parallel with the tension bearing
strap member 350, as shown in FIG. 26. In that position it slides
freely through the opening defined by the sling strap receiving
loop 346. When the tension bearing strap member is in place
extending through the sling strap receiving loop 346, the toggle is
inserted through the D-ring 352 and allowed to assume the
orientation shown in FIGS. 21 and 25 to connect or disconnect the
sling end mounting loop assembly 258 to the buttstock attachment
loop assembly 254.
[0119] The forestock attachment loop assembly 264, as shown in
FIGS. 22 and 29, is generally similar to the buttstock attachment
loop assembly 254, except that a forestock-encircling strap member
366 is shorter than the corresponding buttstock-encircling strap
member 334. Toggle members 336' and 337' thus are fastened to
opposite ends of the forestock-encircling strap 366, and the
assembly 264 includes a sling strap receiving loop 346' and an
adjustment buckle 338'.
[0120] As shown in FIGS. 21, 22, and 29, the forestock attachment
loop assembly 264 includes the sling swivel attachment unit 266,
which receives the toggle stopper members 336' and 337' of the
forestock encircling strap 366 in D-rings 340', 342' the same way
in which the buttstock-encircling strap 334 is received by the
sling swivel attachment device 256 shown attached to the rear sling
swivel 170. The sling swivel attachment unit 266, however, includes
a short strap member 370 that is passed through the forward sling
swivel 132 of the automatic rifle 22 and then engaged with the
tribar slide buckle 372, held in place by a sewn or otherwise
securely fastened loop formed in the opposite end of the strap 370,
on the opposite side of the transversely-extending engagement
D-ring holding strap member 374.
