Description
PRIORITY INFORMATION
[0001] This application is a Continuation of U.S. application Ser.
No. 14/603,075, filed Jan. 22, 2015, the entire contents of which
are hereby incorporated by reference.
FIELD OF DISCLOSURE
[0002] Embodiments of the present disclosure are directed to
firearms, specifically charging handles for automatic and
semi-automatic firearms.
BACKGROUND
[0003] A charging handle (or charge handle) can be incorporated for
ejecting spent cartridges and loading the chamber of a firearm,
such as an M-16, AR-10, AR-15, or M-4. The charging handle can be
configured to move the bolt assembly or carrier back and forth by
means of a bolt engaging element at a forward end of the charging
handle rod. Common charging handles are configured as an elongate
rod with a rearward handle disposed in a perpendicular orientation
with respect to the rod (commonly described as a "T" shape); the
handle is grasped and pulled backward, which moves the rod (and the
bolt carrier to which it is engaged) in a rearward direction.
Charging handles can include latching mechanisms, commonly called
tactical latches, to prevent unintended rearward movement of the
charging handle during operation or inspection of the weapon. The
forward end of the latch engages a detent on the side of the
receiver housing, thereby holding the charging handle in
position.
[0004] While these firearms have certain recognized advantages in
different situations, problems have been identified with commonly
available charging handles. For example, most charging handles have
been designed for right-handed operators; supporting the rifle with
the left hand, the operator uses two fingers of the right hand (one
on either side of the charging handle rod) to pull rearwards on the
charging handle in a straight line parallel to the bolt carrier of
the rifle, requiring the operator to remove the right hand from the
weapon trigger.
[0005] Ambidextrous charging handles have been developed in an
attempt to address this, but it has been noted that such handles do
not always pull the rod parallel with the bolt carrier as
originally designed, but rather cause some degree of rotation and
resultant stress on the rod. This creates resistance while trying
to pull the bolt carrier to the rear of the weapon, resulting in
increased wear on the pin, rod and upper receiver.
[0006] In some instances, an operator's dexterity may be limited
when operating a charging handle. For example, the operator may be
wearing gloves or may have been injured during combat. Also, the
addition of one or more optics (e.g., a top-mounted scope) may
interfere with the ability for an operator to grasp a commonly
available charging handle with two fingers in order to pull the
charging handle rearwards. Charging handles having oversized handle
protrusions, often perpendicular to the firearm, have been
developed to address these issues. However, these approaches yield
similar problems caused by rotational stress on the rod including
increased wear on the pin, rod and upper receiver. Further, it has
been found that many charging handles, with their oversized handle
protrusions, present a potential for snagging on clothing, which
can disrupt operation of the firearm at a crucial moment.
[0007] Thus, it is desired to provide a firearm charging handle
that does not have the ineffectiveness or drawbacks of the above
described charging handles.
SUMMARY
[0008] The present disclosure therefore seeks to provide a firearm
charging handle that allows a more intuitive operation and can
address the issues around some currently available charging
handles.
[0009] One or more embodiments of the present disclosure include a
charging handle for a firearm, a charging handle assembly for a
firearm, and a firearm including a charging handle assembly. For
the various embodiments, the charging handle includes: an elongate
member having a forward end and a rearward end with a longitudinal
axis extending therethrough, a bolt engaging element at the forward
end, a handle portion at the rearward end, the handle portion
including a first projection from the elongate member and a second
projection from the elongate member opposing the first projection,
the first projection having a first surface defining an elongate
opening at least partially therethrough extending substantially
parallel with the longitudinal axis of the elongate member and
configured to receive a first end of a lanyard, and the second
projection having at least one surface defining a pivot point
opening with a pivot axis substantially perpendicular to the
longitudinal axis of the elongate member, a pivot pin in the pivot
point opening, and a latch having a surface defining a first
opening therethrough, the pivot pin passing through the first
opening to allow the latch to pivot around the pivot pin positioned
through the pivot opening and the first opening through the
latch.
[0010] In one or more embodiments, the charging handle assembly
includes an elongate member having a forward end and a rearward end
with a longitudinal axis extending therethrough, a bolt engaging
element at the forward end, a handle portion at the rearward end,
the handle portion including a first projection from the elongate
member and a second projection from the elongate member opposing
the first projection, the first projection having a first surface
defining an elongate opening at least partially therethrough
extending substantially parallel with the longitudinal axis of the
elongate member and configured to receive a first end of a lanyard,
and the second projection having at least one surface defining a
pivot point opening with a pivot axis substantially perpendicular
to the longitudinal axis of the elongate member, a pivot pin in the
pivot point opening, a latch having a surface defining a first
opening therethrough, the pivot pin passing through the first
opening to allow the latch to pivot around the pivot pin positioned
through the pivot opening and the first opening through the latch,
and a lanyard having at least one filament with a first end portion
and a second end portion opposite the first end portion, the first
end portion passing through the elongate opening of the first
projection and the second end portion passing through the second
opening of the latch to form a loop portion, where each of the
first end portion and the second end portion is modified to prevent
the loop from being broken.
[0011] In one or more embodiments, the firearm includes a firearm
charging handle including an elongate member having a forward end
and a rearward end with a longitudinal axis extending therethrough,
a bolt engaging element at the forward end, a handle portion at the
rearward end, the handle portion including a first projection from
the elongate member and a second projection from the elongate
member opposing the first projection, the first projection having a
first surface defining an elongate opening at least partially
therethrough extending substantially parallel with the longitudinal
axis of the elongate member and configured to receive a first end
of a lanyard, and the second projection having at least one surface
defining a pivot point opening with a pivot axis substantially
perpendicular to the longitudinal axis of the elongate member, a
pivot pin in the pivot point opening, and a latch having a surface
defining a first opening therethrough, the pivot pin passing
through the first opening to allow the latch to pivot around the
pivot pin positioned through the pivot opening and the first
opening through the latch.

DETAILED DESCRIPTION
[0020] In the following detailed description of the present
disclosure, reference is made to an accompanying drawing that forms
a part hereof, and in which is shown by way of illustration how one
or more embodiments of the disclosure may be practiced. These
embodiments are described in sufficient detail to enable those of
ordinary skill in the art to practice the embodiments of this
disclosure, and it is to be understood that other embodiments may
be utilized and that process, chemical and/or structural changes
may be made without departing from the scope of the present
disclosure.
[0021] The figures herein follow a numbering convention in which
the first digit or digits corresponds to the drawing figure number
and the remaining digits identify an element in the drawing.
Similar elements between different figures may be identified by the
use of similar digits. For example, 102 may reference element "02"
in FIG. 1, and a similar element may be referenced as 202 in FIG.
2. The proportion and the relative scale of the elements provided
in the figures are intended to illustrate various embodiments of
the present invention and are not to be used in a limiting
sense.
[0022] The present disclosure provides embodiments for a firearm
charging handle, a firearm charging handle assembly, and a firearm
including the firearm charging handle assembly. One or more
embodiments according to the present disclosure allow for
disengagement of the charging handle latch and rearward movement of
the charging handle, and the bolt carrier to which it is engaged,
by a simple rearward pull of a lanyard secured to the charging
handle.
[0023] Embodiments of the present disclosure have been found to be
particularly useful in firearm systems such as the AR-10, AR-15,
M-16, and M4 series, and all subsequent AR-10 type, AR-15 type,
M-16 type, and M4 type firearms and derivatives thereof. These
firearm systems are manufactured and/or sold by entities such as
Colt's Manufacturing Company of Hartford, Conn., Fabrique Nationale
d'Herstal (FN) of Herstal, Belgium, Bushmaster Firearms
International of Madison, N.C., Defense Procurement Manufacturing
Services (DPMS) Panther Arms of St. Cloud Minn., and many others.
However, it will be recognized by those skilled in the art that the
present invention may be applied without undue effort or
experimentation to other firearm types.
[0024] Unlike embodiments of the present disclosure, past
approaches have been ineffective for their purpose. Some approaches
(e.g., those comparable to the charging handle disclosed in U.S.
Pat. No. 8,261,649 (Fitzpatrick) or U.S. Pat. No. 8,820,210
(Melville)) include an oversized protrusion extending from a side
of the charging handle. These protrusions may be termed levers,
knobs, handles, etc. As noted above, such protrusions do not always
cause the rod to be pulled parallel with the bolt carrier as
designed, but rather cause some degree of rotation and resultant
stress on the rod. This can create resistance while trying to pull
the bolt carrier to the rear of the firearm, resulting in increased
wear on the pin, rod and upper receiver. Additionally, the
protrusion may present a potential for snagging on clothing, which
can disrupt operation of the firearm at a crucial moment.
[0025] Other approaches (e.g., those comparable to the charging
handle disclosed in U.S. Pat. No. 7,900,546 (Bordson)) include
mechanisms to allow ambidextrous operation of the charging handle.
These mechanical systems may require precise mechanical movement
and multiple moving parts, the operation of which may be
compromised upon repeated impact or other stress.
[0026] Whereas past approaches may be ineffective, complex, and/or
damaging to firearms, embodiments of the present disclosure provide
for rearward travel of the charging handle parallel with a
longitudinal axis of the firearm without rotation and resultant
stress on the rod. Further, embodiments of the present disclosure
do so without the use of costly and complex moving parts, which may
be subject to mechanical failure at a time the operator needs them
the most. Additionally, in contrast to previous approaches,
embodiments of the present disclosure can be used by those having
difficulty manipulating small parts (e.g., those with disabilities
such as arthritis), those having limited strength, and/or small
hands.
[0027] FIG. 1 illustrates an exploded view of a charging handle 100
according to one or more embodiments of the present disclosure. The
charging handle 100 includes an elongate member 102 having a
forward end 104 and a rearward end 106 with a longitudinal axis 108
extending therethrough. At the forward end 104 is a bolt engaging
element 110 configured to engage a bolt carrier of a firearm and
allow movement of a bolt assembly forward or rearward. At the
rearward end 106 is a handle portion 112.
[0028] The handle portion 112 includes a first projection 112-1
(e.g., a first projection from the elongate member 102) and a
second projection 112-2 opposing the first projection 112-1. The
first projection 112-1 includes a first surface defining an
elongate opening 114. The elongate opening 114 extends at least
partially through the first projection 112-1 and is substantially
parallel with the longitudinal axis 108. The elongate opening 114
can be configured to receive a first end of a lanyard (discussed
below), for instance.
[0029] The second projection 112-2 includes at least one surface
defining a pivot point opening 116 with a pivot axis substantially
perpendicular to the longitudinal axis 108. The charging handle 100
can include a latch 120 which can be secured (e.g., pivotally
secured) to the second projection 112-2 via a pin 118 passing
through (e.g., into) the pivot point opening 116 of the second
projection 112-2 and a first opening 122 through the latch 120 (the
first opening 122 being defined by a surface of the latch 120).
[0030] The latch 120 can include a first portion 121 that includes
the first opening 122 to receive the pivot pin 118. The first
portion 121 of the latch 120 can be positioned between and
substantially parallel with two major surfaces (e.g., a top and a
bottom) of the handle portion 112. The latch 120 can include a
second portion 123 that extends from the first portion 121 and the
longitudinal axis 108 to a third portion 125 that includes a second
surface defining a second opening 124. As shown, the second portion
123 can twist around an axis that passes through the first portion
121 the second portion 123 and the third portion 125 (e.g., an axis
substantially perpendicular to the longitudinal axis 108). The
third portion 125 is not limited to a particular shape. For
example, in some embodiments, the third portion 125 may be
substantially squared, and in other embodiments rounded. The third
portion 125 may resemble a crosshairs (e.g., a circle having
perpendicular intersecting line segments therein), for instance. In
some embodiments, the third portion may be D-shaped. It is to be
understood that other shapes are in accordance with embodiments of
the present disclosure.
[0031] As noted, the latch 120 can be pivotally secured to the
handle portion 112 (e.g., the second projection 112-2 of the handle
portion 112) via the pin 118. The latch 120 can be pivotal about
the pin 118 between a latched orientation and an unlatched
orientation. The latch 120 can include a biasing mechanism
configured to bias the latch 120 in the latched orientation. For
example, the embodiment illustrated in FIG. 1 includes a spring 126
configured to bias the latch 120 in the latch orientation.
[0032] As shown in the embodiment illustrated in FIG. 1, the first
projection 112-1 (e.g., the first surface of the first projection
112-1) can include a second surface defining a concentric opening
128. The concentric opening 128 can be substantially parallel with
the elongate opening 114 and the longitudinal axis 108. The
concentric opening 128 can have a diameter larger than a diameter
of the elongate opening 114. A transition between the concentric
opening 128 and the elongate opening 114 (e.g., the second surface
defining the concentric opening 128 and the first surface defining
the elongate opening 114) can define an annular ledge 130.
[0033] As will be discussed further below, the first end of a
lanyard can be passed through the elongate opening 114, through the
concentric opening 128, and can be modified and/or sized to pass
back through the concentric opening 128 and seat against the
annular ledge 130 (e.g., when the lanyard is pulled). Accordingly,
the modification can prevent the first end of the lanyard from
being withdrawn back through the elongate opening 114.
[0034] The second surface defining the second opening 124 through
the latch 120 can be configured to receive a second end of the
lanyard (discussed below), for instance. In some embodiments, a
geometric center of the second opening 124 through the latch 120
and a geometric center of the elongate opening 114 can be disposed
on a common plane parallel with the longitudinal axis 108. In some
embodiments, the geometric center of the second opening 124 through
the latch 120, the geometric center of the elongate opening 114,
and the longitudinal axis 108 can be disposed on the common
plane.
[0035] It is noted that although embodiments of the present
disclosure are not intended to be limited to particular materials,
the elongate member 102, the latch 120, the pin 118, and/or the
spring 126 can be composed of metal or metal alloys (e.g., steel
and/or aluminum), for instance.
[0036] FIG. 2 illustrates a top view of a charging handle 200
according to one or more embodiments of the present disclosure. The
charging handle 200 is analogous in several respects to the
charging handle 100 previously described in connection with FIG. 1.
For instance, the charging handle 200 includes an elongate member
202 having a forward end 204 and a rearward end 206. At the forward
end 204 is a bolt engaging element 210 configured to engage a bolt
carrier of a firearm and allow movement of a bolt assembly forward
or rearward. At the rearward end 206 is a handle portion 212.
[0037] Similarly, the handle portion 212 includes a first
projection 212-1 (e.g., a first projection from the elongate member
202) and a second projection 212-2 opposing the first projection
212-1. The first projection 212-1 includes a first surface defining
an elongate opening 214. The elongate opening 214 extends at least
partially through the first projection 212-1. The elongate opening
214 can be configured to receive a first end of a lanyard, for
instance. The second projection 212-2 includes a pin 218 passing
through (e.g., into) the second projection 212-2, securing the
second projection 212-2 to a latch 220. The latch 220 includes a
second surface defining a second opening 224. As previously
discussed, the latch 220 can be pivotally secured to the handle
portion 212 (e.g., the second projection 212-2 of the handle
portion 212) via the pin 218. The latch 220 can be pivotal about
the pin 218 between a latched orientation and an unlatched
orientation. The latch 220 can include a biasing mechanism (not
shown) configured to bias the latch 220 in the latched orientation.
The embodiment illustrated in FIG. 2 shows the latch in the latched
orientation.
[0038] The embodiment illustrated in FIG. 2 includes an adjoining
opening 232 (e.g., adjoining to the elongate opening 214) defined
by a second surface of the first projection 212-1. The adjoining
opening 232 can be substantially perpendicular to the elongate
opening 214 and/or a longitudinal axis of the elongate member 202,
though embodiments of the present disclosure are not so limited.
The adjoining opening 232 connects with the elongate opening 214.
In some embodiments, such as the embodiment shown in FIG. 2, the
adjoining opening 232 can pass partially (and not fully) through
the first projection 212-1. In other embodiments, the adjoining
opening 232 can pass through (e.g., fully through) the first
projection 212-1. In some embodiments, such as the embodiment shown
in FIG. 2, the adjoining opening 232 can pass through a bottom
surface of the first projection 212-2. In other embodiments, the
adjoining opening 232 can pass through a top surface of the first
projection 212-2 or a distal (e.g., side) surface of the first
projection 212-2.
[0039] In some embodiments, a diameter of the adjoining opening 232
is larger than a diameter of the elongate opening 214. In other
embodiments, the diameter of the adjoining opening 232 is not
larger than the diameter of the elongate opening 214 (i.e.,
substantially equivalent to, or smaller than, a diameter of the
elongate opening 214). The first end of a lanyard can be passed
through the elongate opening 214, through the adjoining opening
232, and can be modified. In embodiments where the diameter of the
adjoining opening 232 is larger than the diameter of the elongate
opening 214, the modified first end of the lanyard can be sized to
pass through the adjoining opening 232 and seat against the second
surface defining the adjoining opening 232 (e.g., when the lanyard
is pulled). Accordingly, the modification can prevent the first end
of the lanyard from being withdrawn back through the elongate
opening 214. In embodiments where the diameter of the adjoining
opening 232 is not larger than the diameter of the elongate opening
214, the modified first end of the lanyard can be sized to seat
against a surface through which the adjoining opening passes and
thereby prevent the first end of the lanyard from being withdrawn
back through both the adjoining opening 232 and the elongate
opening 214.
[0040] FIG. 3 illustrates a perspective view of a charging handle
assembly 300 according to one or more embodiments of the present
disclosure. The charging handle assembly 300 is analogous in
several respects to the charging handle 100 previously described in
connection with FIG. 1. For instance, the charging handle assembly
300 includes an elongate member 302 having a forward end 304 and a
rearward end 306. At the forward end 304 is a bolt engaging element
310 configured to engage a bolt carrier of a firearm and allow
movement of a bolt assembly forward or rearward. At the rearward
end 306 is a handle portion 312.
[0041] Similarly, the handle portion 312 includes a first
projection 312-1 (e.g., a first projection from the elongate member
302) and a second projection 312-2 opposing the first projection
312-1. The first projection 312-1 includes a first surface defining
an elongate opening 314. The elongate opening 314 extends at least
partially through the first projection 312-1. The elongate opening
314 can be configured to receive a first end 334-1 of a lanyard
334, for instance. The second projection 312-2 includes a pin 318
passing through (e.g., into) the second projection 312-2, securing
the second projection 312-2 to a latch 320. The latch 320 includes
a second surface defining a second opening 324. As previously
discussed, the latch 320 can be pivotally secured to the handle
portion 312 (e.g., the second projection 312-2 of the handle
portion 312) via the pin 318. The latch 320 can be pivotal about
the pin 318 between a latched orientation and an unlatched
orientation. The latch 320 can include a biasing mechanism (not
shown) configured to bias the latch 320 in the latched orientation.
The embodiment illustrated in FIG. 3 shows the latch in the latched
orientation.
[0042] As shown in the embodiment illustrated in FIG. 3, the first
projection 312-1 (e.g., the first surface of the first projection
312-1) can include a second surface defining a concentric opening
328. The concentric opening 328 can be substantially parallel with
the elongate opening 314 and a longitudinal axis of the elongate
member 302. The concentric opening 328 can have a diameter larger
than a diameter of the elongate opening 314. A transition between
the concentric opening 328 and the elongate opening 314 (e.g., the
second surface defining the concentric opening 328 and the first
surface defining the elongate opening 314) can define an annular
ledge 330.
[0043] As shown, the first end 334-1 of the lanyard 334 can be
passed through the elongate opening 314, through the concentric
opening 328, and can be modified to a modified first end 336. The
modified first end 336-1 can be sized to pass through the
concentric opening 328 and seat against the annular ledge 330
(e.g., when the lanyard 334 is pulled). Accordingly, the modified
first end 336-1 of the lanyard 334 can be prevented from being
withdrawn back through the elongate opening 314.
[0044] The second surface defining the second opening 324 through
the latch 320 can be configured to receive a second end 334-2 of
the lanyard 334. As shown, the second end 334-2 of the lanyard 334
can be passed through the second opening 324 and can be modified to
a modified second end 336-2. The modified second end 336-2 can be
sized to seat against a surface of the latch 320 (e.g., when the
lanyard 334 is pulled). Accordingly, the modified second end 336-2
of the lanyard 334 can be prevented from being withdrawn back
through the second opening 324. The first end 334-1 of the lanyard
334 passing through the first projection 312-1 and the second end
334-2 of the lanyard 334 passing through the latch 320 form a loop
portion 334-3, which is prevented from being broken by the modified
first end 336-1 and the modified second end 336-2. A size of the
loop portion 334-3 can be selected to accept a finger therein. In
some embodiments, a size of the loop portion 334-3 can be selected
to accept a gloved finger therein.
[0045] The lanyard 334 can include at least one filament. In some
embodiments, the lanyard 334 can include a plurality of filaments,
which may be braided together. In some embodiments, the at least
one filament can be a synthetic polymer, such as a nylon resin, for
instance. A suitable example of a nylon resin includes, but is not
limited to, Zytel.RTM. nylon resin (DuPont). In some embodiments,
the at least one filament can be a naturally-occurring substance,
such as leather or hemp, for instance. In some embodiments, the at
least one filament can be a metal or a metal alloy. In some
examples, the lanyard 334 can be a cord, wire, string, thread,
and/or cable, though embodiments of the present disclosure are not
so limited.
[0046] The modification to either the first end 334-1 or the second
end 334-2 to form the modified first end 336-1 and the modified
second end 336-2 can be a modification selected such that either
the modified first end 336-1 or the modified second end 336-2 is
prevented from being withdrawn through its respective opening. In
some embodiments modifying can include increasing a cross-sectional
area of the end(s) of the lanyard 334. In some embodiments,
modifying can include increasing a diameter of the end(s) of the
lanyard 334. In some embodiments, the end(s) of the lanyard 334 can
be knotted (e.g., in an overhand knot). In some embodiments, the
end(s) of the lanyard 334 can be compressed and/or stretched to
prevent withdrawal. In some embodiments, the end(s) of the lanyard
can be secured to one or more mechanical stops. Mechanical stops in
accordance with embodiments of the present disclosure are not
limited to a particular shape and can include beads, plates, bars,
balls, and/or blocks, among others. Securing the end(s) of the
lanyard to one or more mechanical stops can include knotting,
binding, welding, soldering, fusing, adhering, fastening, and/or
melding, among others.
[0047] The loop portion 334-3 of the lanyard 334 can include a user
engagement element 338 (e.g., to receive a finger of a user). The
user engagement element 338 can have a surface area greater than a
surface area of the loop portion 334-3, for instance, to provide
ergonomic comfort to a user pulling on the lanyard 334. The user
engagement element 338 may be a flap, a patch, a strip, a strap, a
pad, or others. The user engagement element 338 may be composed of
a synthetic polymer, such as a nylon resin, for instance. A
suitable example of a nylon resin includes, but is not limited to,
Zytel.RTM. nylon resin (DuPont). The user engagement element 338
may be composed of a naturally-occurring substance, such as
leather, for instance. The user engagement element 338 may have a
radius of curvature adapted to receive a finger, or, in some
embodiments, a gloved finger. The user engagement element 338 may
include a rough and/or textured surface, such as striations, cross
hatching or knurling, for instance.
[0048] In some embodiments, the user engagement element 338 may be
of unitary construction (e.g., as shown in the embodiment
illustrated in FIG. 3). In other embodiments, the user engagement
element 338 may include one or more components. For example, the
user engagement element 338 may include a plurality of fibers
(e.g., parachute cord and/or 550 cord) woven together. Such a weave
can include, for example, a braid knot, a chain sinnet, and/or a
Portuguese sinnet, among others.
[0049] In some embodiments, the user engagement element 338 may
include one or more knots tied using the loop portion 334-3 of the
lanyard 334. In one such example, the user engagement element 338
can include a monkey's fist (or monkey paw) at the loop portion
334-3. A user, in addition to having the capability of pulling
rearward on the loop portion 334 by inserting a finger therein, can
grasp the knot and pull rearward.
[0050] The user engagement element 338 can be configured to
magnetically engage one or more portions of a firearm. Accordingly,
the lanyard 334 can be secured in a desired position when not in
use. Such embodiments are discussed further below in connection
with FIG. 5.
[0051] FIG. 4 illustrates a perspective view of a charging handle
assembly 400 according to one or more embodiments of the present
disclosure. The charging handle assembly 400 is analogous in
several respects to the charging handle 200 previously described in
connection with FIG. 2. For instance, the charging handle assembly
400 includes an elongate member 402 having a forward end 404 and a
rearward end 406. At the forward end 404 is a bolt engaging element
410 configured to engage a bolt carrier of a firearm and allow
movement of a bolt assembly forward or rearward. At the rearward
end 406 is a handle portion 412.
[0052] Similarly, the handle portion 412 includes a first
projection 412-1 (e.g., a first projection from the elongate member
402) and a second projection 412-2 opposing the first projection
412-1. The first projection 412-1 includes a first surface defining
an elongate opening 414. The elongate opening 414 extends at least
partially through the first projection 412-1. The elongate opening
314 can be configured to receive a first end 434-1 of a lanyard
434, for instance. The second projection 412-2 includes a pin 418
passing through (e.g., into) the second projection 412-2, securing
the second projection 412-2 to a latch 420. The latch 420 includes
a second surface defining a second opening 424. As previously
discussed, the latch 420 can be pivotally secured to the handle
portion 412 (e.g., the second projection 412-2 of the handle
portion 12) via the pin 418. The latch 420 can be pivotal about the
pin 418 between a latched orientation and an unlatched orientation.
The latch 420 can include a biasing mechanism (not shown)
configured to bias the latch 420 in the latched orientation. The
embodiment illustrated in FIG. 4 shows the latch in the latched
orientation.
[0053] In a manner analogous to the charging handle 200 previously
described in connection with FIG. 2, the embodiment illustrated in
FIG. 4 includes an adjoining opening 432 (e.g., adjoining to the
elongate opening 414) defined by a second surface of the first
projection 412-1. The adjoining opening 428 can be substantially
perpendicular to the elongate opening 414 and/or a longitudinal
axis of the elongate member 402, though embodiments of the present
disclosure are not so limited. The adjoining opening 432 connects
with the elongate opening 414. In some embodiments, such as the
embodiment shown in FIG. 4, the adjoining opening 432 can pass
partially (and not fully) through the first projection 412-1. In
other embodiments, the adjoining opening 432 can pass through
(e.g., fully through) the first projection 412-1. In some
embodiments, such as the embodiment shown in FIG. 4, the adjoining
opening 432 can pass through a bottom surface of the first
projection 412-2. In other embodiments, the adjoining opening 432
can pass through a top surface of the first projection 412-2 or a
distal (e.g., side) surface of the first projection 412-2.
[0054] As shown in the embodiment illustrated in FIG. 4, a diameter
of the adjoining opening 432 can be larger than a diameter of the
elongate opening 214. The first end 434-1 of a lanyard 434 can be
passed through the elongate opening 414, through the adjoining
opening 432, and can be modified to a modified first end 436-2. The
modified first end 436-1 is illustrated as a mechanical stop in the
charging handle assembly 400, though, as previously discussed,
embodiments of the present disclosure are not so limited. The
modified first end 436-1 of the lanyard 434 can be sized to pass
through the adjoining opening 432 and seat against the second
surface defining the adjoining opening 432 (e.g., when the lanyard
434 is pulled). Accordingly, the modified first end 436-1 of the
lanyard 434 can be prevented from being withdrawn back through the
elongate opening 414.
[0055] The second surface defining the second opening 424 through
the latch 420 can be configured to receive a second end 434-2 of
the lanyard 434. As shown, the second end 434-2 of the lanyard 434
can be passed through the second opening 424 and can be modified to
a modified second end 436-2. The modified second end 436-2 can be
sized to seat against a surface of the latch 420 (e.g., when the
lanyard 434 is pulled). Accordingly, the modified second end 436-2
of the lanyard 434 can be prevented from being withdrawn back
through the second opening 424. The first end 434-1 of the lanyard
434 passing through the first projection 412-1 and the second end
434-2 of the lanyard 434 passing through the latch 420 form a loop
portion 434-3. A size of the loop portion 434-3 can be selected to
accept a finger therein. In some embodiments, a size of the loop
portion 434-3 can be selected to accept a gloved finger
therein.
[0056] In contrast to the charging handle 300 illustrated in FIG.
3, the embodiment shown in FIG. 4 does not include a user
engagement element. In some examples, users may engage the loop
portion 434-3 of the lanyard directly with a finger, for instance.
In some embodiments, users may engage the loop portion 434-3 with a
device, such as a hook, calipers, or bow string drawing and
releasing device, for instance, among others.
[0057] FIG. 5 illustrates a perspective view of a firearm 536
having a charging handle assembly 500 according to one or more
embodiments of the present disclosure.
[0058] The Firearm 536 can be an AR-10, AR-15, M-16, or M4 series,
or a subsequent AR-10 type, AR-15 type, M-16 type, and M4 type
firearm or derivative thereof. These firearms are manufactured
and/or sold by entities such as Colt's Manufacturing Company of
Hartford, Conn., Fabrique Nationale d'Herstal (FN) of Herstal,
Belgium, Bushmaster Firearms International of Madison, N.C.,
Defense Procurement Manufacturing Services (DPMS) Panther Arms of
St. Cloud Minn., and many others.
[0059] Visible in the embodiment illustrated in FIG. 5 is a lanyard
534 attached to a handle portion of the charging handle assembly
500 through an annular opening 528. The lanyard 534 includes a loop
portion 534-3, which includes a user engagement element 538. The
charging handle assembly illustrated in FIG. 5 may be analogous to
the charging handle assembly 300 previously described in connection
with FIG. 3. Some elements of the charging handle assembly 500 are
obscured by other portions of the firearm 536. For instance, a
portion of an elongate member of the charging handle assembly is
disposed in a channel of the firearm 536.
[0060] A force applied rearward to the loop portion 534-3 (e.g.,
via the user engagement element 538) can move a latch of the
charging handle 500 from a latched orientation to an unlatched
orientation. Subsequent force applied rearward (e.g., force applied
after the latch has been moved to the unlatched orientation) can
move the charging handle assembly 500 rearward in the channel.
Thus, a user applying a pulling force to the loop portion 534-3 of
the lanyard 534 can unlatch the charging handle assembly 500 and
slide it rearward in the channel.
[0061] As previously discussed, the user engagement element 538 can
be configured to magnetically engage one or more portions of the
firearm 536. That is, the loop portion 534-3 of the lanyard 534 can
be secured in a desired position when not in use. In one example,
the user engagement element 538 can include a monkey's fist knot
tied around a magnet (e.g., a neodymium magnet). The magnet can
magnetically engage one or more portions (e.g., magnetic and/or
ferromagnetic portions) of the firearm 536. Accordingly, the knot
can be configured to be secured at a desired position, such as
either side of a butt plate adapter of the firearm 536 and/or a
particular location on a stock of the firearm 536, for
instance.
[0062] In other embodiments, the user engagement element can
include a monkey's fist knot tied around a ferromagnetic component
(e.g., a steel ball). One or more magnets can be secured to the
firearm 536 (e.g., in the stock or on the butt plate adapter) and
configured to magnetically engage and secure the knot at a
particular location with respect to the firearm 536. The magnets
can be secured to a surface of the firearm 536 and/or recessed into
(or under) a surface of the firearm 536.
[0063] FIG. 6 illustrates a perspective view of a firearm 636
having a telescopic sight (e.g., scope) 640 and a charging handle
assembly 600 according to one or more embodiments of the present
disclosure.
[0064] The Firearm 636 can be an AR-10, AR-15, M-16, or M4 series,
or a subsequent AR-10 type, AR-15 type, M-16 type, and M4 type
firearm or derivative thereof. These firearms are manufactured
and/or sold by entities such as Colt's Manufacturing Company of
Hartford, Conn., Fabrique Nationale d'Herstal (FN) of Herstal,
Belgium, Bushmaster Firearms International of Madison, N.C.,
Defense Procurement Manufacturing Services (DPMS) Panther Arms of
St. Cloud Minn., and many others.
[0065] The telescopic sight 640 is an optical device configured to
be mounted on (or affixed to) the firearm 636 and is not intended
to be limited to a particular type, style, size, and/or
configuration. For example, the telescopic sight 640 can include
one or more lens hoods, covers, and/or optical filters. The
telescopic sight 640 can include an illuminated reticle, fiber
optic components, batteries, infrared imaging capabilities,
etc.
[0066] Visible in the embodiment illustrated in FIG. 6 is a lanyard
634 attached to a handle portion of the charging handle assembly
600 through an annular opening 628. The lanyard 634 includes a loop
portion 634-3, which includes a user engagement element 638. The
charging handle assembly illustrated in FIG. 6 may be analogous to
the charging handle assembly 300 previously described in connection
with FIG. 3. Some elements of the charging handle assembly 600 are
obscured by other portions of the firearm 636. For instance, a
portion of an elongate member of the charging handle assembly is
disposed in a channel of the firearm 636.
[0067] A force applied rearward to the loop portion 634-3 (e.g.,
via the user engagement element 638) can move a latch of the
charging handle 600 from a latched orientation to an unlatched
orientation. Subsequent force applied rearward (e.g., force applied
after the latch has been moved to the unlatched orientation) can
move the charging handle assembly 600 rearward in the channel.
Thus, a user applying a pulling force to the loop portion 634-3 of
the lanyard 634 can unlatch the charging handle assembly 600 and
slide it rearward in the channel.
[0068] Whereas, under previous approaches, a user may find
difficulty grasping a charging handle when a telescopic sight (or
other optical device), such as the telescopic sight 640, is mounted
on the firearm 636, the embodiment illustrated in FIG. 6
illustrates that the loop portion 634-3 of the lanyard 634 is
readily accessible as it is located rearward of the telescopic
sight 640. Thus, a user can operate the charging handle 600 without
being impeded by the presence of the telescopic sight 640.
[0069] Although specific embodiments have been illustrated and
described herein, those of ordinary skill in the art will
appreciate that any arrangement calculated to achieve the same
techniques can be substituted for the specific embodiments shown.
This disclosure is intended to cover any and all adaptations or
