Description
RELATED APPLICATIONS
[0001] This application is a continuation-in-part of application
having Ser. No. 10/877,013 (filed on Jun. 26, 2004, entitled
"Mirror Sight Apparatus For Guns" and having a common applicant
herewith).
FIELD OF THE DISCLOSURE
[0002] The inventive disclosures made herein relate generally to
sighting apparatuses and systems for guns and, more particularly,
to apparatuses and systems configured for enabling a gun to be
fired from cover positions in an aimed manner.
BACKGROUND
[0003] Apparatuses that are configured for use on a gun (e.g. a
rifle, a handgun, paintball gun, etc.) for permitting a shooter of
the gun to fire it from a cover position in an aimed manner are
known (i.e., conventional cover-position sighting apparatuses).
Examples of such apparatuses are disclosed in U.S. Pat. Nos.
6,643,969; 6,311,424; 3,863,354; 3,262,440; 1,264,133; 1,260,285;
1,227,544; 880,378; 813,932; 694,904 and 187,432. In permitting a
shooter of the gun to fire it from a cover position in an aimed
manner, the shooter of the gun is able to remain substantially out
of a line of enemy fire while being able to fire at hostile targets
in an aimed manner. Firing in this manner in a hostile or
potentially hostile engagement saves lives and saves ammunition,
both of which are important endeavours in a hostile or potentially
hostile engagement.
[0004] Such conventional cover-position sighting apparatuses are
known to have limitations that adversely affect their
effectiveness, desirability and/or practicality. One limitation of
certain conventional cover-position sighting apparatuses is that
they are inefficient in enabling a desired target to be accurately
and timely acquired, even with excessive training. This is
unacceptable as it puts shooters at risk and such training can
often be in conflict with preferred engagement tactics. Some of
such conventional apparatuses have the limitation of making a gun
cumbersome due to being non-stowable, being non-removable, being
difficult to remove and/or their physical size. This adversely
impacts their mobility and convenience, makes them susceptible to
damage and/or puts them in the way of other components of the gun.
Another limitation of some conventional apparatuses is that they
generate images that are distorted and/or disorienting, making it
difficult to aim in an accurate and/or repeatable manner. Still
another limitation of some conventional apparatuses is that they
include multiple mirrors that require an undesirably high degree of
alignment for enabling effective aiming. Some conventional
apparatuses require a shooter to have close facial proximity to the
gun in order to acquire a desired target, which is often a
limitation in that this can adversely affect safety of the shooter.
Yet another limitation of some conventional apparatuses is that
they are overly expensive to implement, maintain and/or
replace.
[0005] Therefore, apparatuses and systems configured for enabling a
gun to be fired from cover positions in an aimed manner and that
they at least partially overcome limitations associated with such
conventional approaches for enabling firing from cover positions
would be useful and novel.

mirror assembly and the mounting base. A second one of the positive
positioning structures is provided between the single utilized
mirror and a base attachment portion of the mirror assembly. The
positive positioning structures are jointly enable the single
utilized mirror to be positively positioned in a plurality of
predefined positions. The non-use position of the mirror assembly
is a first one of the predefined positions and the use position of
the mirror assembly is a second one of the predefined
positions.
[0008] In another embodiment, a targeting system for a gun
comprises a mounting rail, a target acquisition apparatus, a
single-mirror target viewing apparatus and a locking structure. The
target acquisition apparatus including a mounting structure
engagable with the mounting rail for enabling the target
acquisition apparatus to be secured to the mounting rail and
includes means for visually indicating when the gun is aimed at a
desired target. The single-mirror target viewing apparatus includes
a mounting base and a mirror assembly movably attached to the
mounting base. The mounting base includes a mounting structure
engagable with the mounting rail for enabling the single-mirror
target viewing target apparatus to be secured to the mounting rail.
The mirror assembly includes a single utilized mirror providing a

the mirror assembly).
[0009] Accordingly, it is a principal object of the present
invention to provide apparatuses and systems configured for
enabling a gun to be fired from cover positions in an aimed manner
and that at least partially overcomes limitations associated with
conventional approaches for enabling firing from cover positions.
Specifically, apparatuses and systems in accordance with
embodiments of the disclosures made herein are simple and timely in
their ability to accurately acquire a desired target, without
requiring excessive training to become proficient in their use
and/or training that is in conflict with preferred engagement
tactics. Such apparatuses and systems are relatively small and
non-obtrusive, which enhances their mobility, durability and
convenience, particularly when configured for being stowable. They
provide clear and intuitive imaging of targets and means for
visually indicating when the gun is aimed at a desired target. They
are mountable in a manner that is simple and that readily permit
their removal. Their single utilized mirror configuration does not
require precision alignment as is required by multiple mirror
apparatuses. Their single utilized mirror can be made large enough
to eliminate the need for close facial proximity to the weapon
while still achieving accurate aiming and providing safety for the
shooter. Finally, they are relatively inexpensive to implement,
maintain and/or replace.
[0010] These and other objects, embodiments, advantages and/or
distinctions of the present invention will become readily apparent
upon further review of the following specification, associated

DETAILED DESCRIPTION OF THE DRAWINGS
[0025] FIGS. 1-3 depict a first embodiment of a gun 10 adapted for
enabling the gun 10 to be fired at a desired target from a cover
position (e.g., around a corner of a wall, from over the top of an
embankment, etc.) in an aimed manner. The gun 10 includes a gun
body 12, a target acquisition apparatus 14 and a single-mirror
target viewing apparatus 16. The gun body 12 includes a receiver 18
and a mounting rail 20 (e.g., weaver rail or picatinny rail)
attached the receiver 18. The single-mirror target viewing
apparatus 16 depicted in FIGS. 1-3 is an embodiment of a
single-mirror target viewing apparatus in accordance with an
embodiment of the inventive disclosures made herein. The target
acquisition apparatus 14 and a single-mirror target viewing
apparatus 16 depicted in FIGS. 1-3 jointly represent a gun sight
system in accordance with an embodiment of the inventive
disclosures made herein.
[0026] The target acquisition apparatus 14 and the single-mirror
target viewing apparatus 16 are attached to the mounting rail 20 of
the gun body 12. As depicted, the target acquisition apparatus 14
and the single-mirror target viewing apparatus 16 are discrete
apparatuses mounted directly on the mounting rail 20 of the gun
body 12. It is contemplated herein that, in other embodiments, (not
shown), the target acquisition apparatus 14 and the single-mirror
target viewing apparatus 16 may be discrete apparatuses indirectly
attached to the mounting rail 20 through a separate mounting device
(e.g., precision-formed interposer rail) or may be an adjoined
assembly (e.g., mounted on a common support structure) that is
attached directly or indirectly to the mounting rail 20.
[0027] Alternately, the target acquisition apparatus 14 and/or the
single-mirror target viewing apparatus 16 may be mounted on or
integrated with components of the gun body 12 other than the
mounting rail 20. For example, the single mirror target viewing
apparatus 16 may be an integral component of the rear iron sights
on a long-barrel gun (e.g., rifle or shot gun) or may be mounted on
a carry handle of a long-barrel gun (e.g., a carrying handle of a
M-16 style rifle).
[0028] As depicted in FIGS. 1-3, the target acquisition apparatus
14 and the single-mirror target viewing apparatus 16 are mounted
above a barrel portion 21 of the gun 10. It is contemplated herein
that the target acquisition apparatus 14 and the single-mirror
target viewing apparatus 16 may be mounted below the barrel portion
21 of the gun 10 or to a side of the barrel portion 21 of the gun
10. The specific mounted location will depend on factors such as
shooter preference, intended application, gun configuration (e.g.,
hand gun, rifle, shotgun, etc.) and gun design (e.g., integral
mounting devices).
[0029] The target acquisition apparatus 14 includes means for
visually indicating when the gun 10 is aimed at a desired target.
Examples of the target acquisition apparatus 14 include optical
sight apparatuses, opto-electical sight apparatuses, and
conventional mechanical sight apparatuses. An optical scope is an
example of an optical sight apparatus. Trijicon brand, Docter Optic
brand and EOTech brand target acquisition apparatuses are examples
of opto-electical sight apparatuses that utilize laser,
holographic, LED reflection and/or optical technologies. Examples
of conventional mechanical sights include mechanical sights
provided on the gun 10 by its original equipment manufacturer and
accessory mechanical sights configured for being attached to the
gun 10 after its manufacture. On a long-barrel gun (e.g., a rifle
or shotgun), if an accessory front sight is required, attaching
such accessory front sight on one side or both of a front tower
sight construction (e.g., on an M-16 style rifle) is one preferred
position. Alternatively, such an accessory front sight could be
affixed to the barrel, to a barrel-insulating device or to an
accessory rail that is attached to the barrel portion 21 or the
receiver 18.
[0030] The single-mirror target viewing apparatus 16 includes a
mirror assembly 22 and a mounting base 24. The mirror assembly 22
is movably attached to the mounting base 24. The mirror assembly 22
includes a single utilized mirror 26 (i.e., one or more redundant
mirrors are contemplated) that defines a target imaging surface
(e.g., reflective surface of the single utilized mirror).
Preferably, the single utilized mirror 26 is essentially flat. The
mounting base 24 is attached to the mounting rail 18 of the gun
body 12.
[0031] The mirror assembly 22 is moveably attached to the mounting
base 24 in a manner enabling the mirror assembly 22 to be pivoted
and rotated with respect to the mounting base 24. In this manner,
the single utilized mirror 26 is movable between a stowed position
S (FIG. 3) and a deployed position D (FIG. 2) and is movable
between a plurality of rotational positions. For example, the
single utilized mirror 26 is movable to a first rotated position R1
(FIG. 1) for achieving a use position U and to a second rotate
position R2 (FIG. 2) for enabling the mirror assembly 22 to be
positioned in the stowed position S. Preferably, an axis of
rotation of the mirror assembly 22 and/or the single utilized
mirror 26 with respect to the mounting base 24 extends through a
central region of the single utilized mirror 26. As disclosed
above, the single utilized mirror 26 defines a target imaging
surface, which as shown in FIGS. 1 and 2 is within the central
region of the single utilized mirror 26. Thus, in at least one
embodiment of the present invention, the axis of rotation of the
single utilized mirror 26 extends through the target imaging
surface of the single utilized mirror 26 when the single utilized
mirror 26 is in a use position U. In this manner, the target
imaging surface of the single utilized mirror 26 is skewed with
respect to the axis of rotation of the single utilized mirror 26
when the single utilized mirror 26 is in the use position U such
that the axis of rotation of the single utilized mirror 26 extends
through the target imaging surface of the single utilized mirror 26
at a single point when the single utilized mirror 26 is in the use
position U. Preferably, but not necessarily, the target imaging
surface of the single utilized mirror 26 is skewed with respect to
the axis of rotation of the single utilized mirror 26 throughout an
entire range of rotation of the single utilized mirror 26 when the
single utilized mirror 26 is in the deployed position D. It should
be understood that the first rotated position R1 depicted in FIG. 1
is one example of a rotated position corresponding to a use
position of the mirror assembly 22.
[0032] It is contemplated herein that, in an alternate embodiment
(not shown) the mirror assembly 22 is positioned adjacent to one of
the sides of the gun body 12 when in the stowed position S.
Preferably, when in such a stowed position S, the single utilized
mirror 26 faces the gun body 12 so as to protect the single
utilized mirror 26 from damage. Optionally, a protective stowage
enclosure (not shown) may be provided in which the single mirror is
positioned when in the stowed position S.
[0033] Preferably, the mirror assembly 22 is selectively securable
in the stowed position S and the deployed position D. In one
embodiment, the mirror assembly 22 and the mounting base 24 are
jointly configured for selectively securing the mirror assembly 22
in the stowed position S and the deployed position D. The mirror
assembly 22 and the mounting base 24 including mating features
(e.g., a biased positioning means and a detent) is one example of
the mirror assembly 22 and the mounting base 24 being jointly
configured for selectively securing the mirror assembly 22 in the
stowed position S and the deployed position D.
[0034] Preferably, the mirror assembly 22 is selectively securable
in one or more rotational positions (e.g., R1, R2, etc.). To this
end, the mirror assembly 22 includes a base attachment portion 28
to which the single utilized mirror 26 is rotatably attached and to
which the mounting base 24 is pivotally attached. In such
embodiment, the base attachment portion 28 and the single utilized
mirror 26 are jointly configured for selectively securing the
single utilized mirror 26 in one or more rotational positions with
respect to the mounting base 24. The single utilized mirror 26 and
the base attachment portion 28 including mating features (e.g., a
biased positioning means and a detent) is one example of the mirror
assembly 22 being configured for enabling the single utilized
mirror 26 to be selectively secured in one or more rotational
positions.
[0035] When in the use position U, the target imaging surface of
the single utilized mirror 26 is in a skewed orientation with
respect to a longitudinal axis of the barrel portion 21 of the gun
10. In this orientation, a desired target and means for visually
indicating when the target is acquired in an aimed manner may be
viewed on the target imaging surface with the gun held in a
partially rotated position (i.e., rotated along its longitudinal
axis to a position between about the 12 o'clock position and about
the 3 o'clock or 9 o'clock positions). Accordingly, the
single-mirror target viewing apparatus 16 enables a shooter to view
on the target imaging surface both the desired target and the means
for visually indicating when the gun is aimed at a desired target,
thereby enabling the gun to be to accurately fired from a cover
position in an aimed manner.
[0036] FIG. 4 depicts a second embodiment of a gun 100 adapted for
enabling the gun 100 to be fired at a desired target from a cover
position (e.g., around a corner of a wall, from over the top of an
embankment, etc) in an aimed manner. The gun 100 includes a gun
body 112, a target acquisition apparatus 114 (i.e., front and rear
physical sights) and a single-mirror target viewing apparatus 116
that is fixedly attached (i.e., non-rotating and non-pivoting) to
the gun body 112. The gun body 112 includes a receiver 118 and a
mounting rail 120 attached the receiver 118. The single-mirror
target viewing apparatus 116 depicted in FIGS. 4 is an embodiment
of a single-mirror target viewing apparatus in accordance with an
embodiment of the inventive disclosures made herein. The target
acquisition apparatus 114 and a single-mirror target viewing
apparatus 116 depicted n FIG. 4 jointly represent a gun sight
system in accordance with an embodiment of the inventive
disclosures made herein.
[0037] The target acquisition apparatus 114 and the single-mirror
target viewing apparatus 116 are attached to the mounting rail 120
of the gun body 112. As depicted, the target acquisition apparatus
114 and the single-mirror target viewing apparatus 116 are discrete
apparatuses mounted directly on the mounting rail 120 of the gun
body 112. It is contemplated herein that, in other embodiments,
(not shown), the target acquisition apparatus 114 and the
single-mirror target viewing apparatus 116 may be discrete
apparatuses indirectly attached to the mounting rail 120 through a
separate mounting device (e.g., precision-formed interposer rail)
or may be an adjoined assembly (e.g., mounted on a common support
structure) that is attached directly or indirectly to the mounting
rail 120.
[0038] As depicted in FIG. 4, the target acquisition apparatus 114
and the single-mirror target viewing apparatus 116 are position to
a right side of the gun body 112. It is contemplated herein that,
in other embodiments (not shown), the target acquisition apparatus
114 and the single-mirror target viewing apparatus 116 may be
positioned to a left side of the gun body 112 or a second
single-mirror target viewing apparatus 116 may be mounted opposite
the first single-mirror target viewing apparatus 116 (i.e.,
opposite the single-mirror target viewing apparatus 116 depicted in
FIG. 4). The specific mounted location and number of target viewing
apparatuses will depend on factors such as shooter preference,
intended application, gun configuration (e.g., hand gun, rifle,
etc) and gun design (e.g., integral mounting devices).
[0039] The target acquisition apparatus 114 includes means for
visually indicating when the gun 100 is aimed at a desired target.
Examples of the target acquisition apparatus 114 include optical
sight apparatuses, opto-electical sight apparatuses, and
conventional mechanical sight apparatuses. An optical scope is an
example of an optical sight apparatus. Trijicon brand, Docter Optic
brand and EOTech brand target acquisition apparatuses are examples
of opto-electical sight apparatuses that utilize laser,
holographic, LED reflection and/or optical technologies. Examples
of conventional mechanical sights include mechanical sights
provided on the gun 100 by its original equipment manufacturer and
accessory mechanical sights configured for being attached to the
gun 10 after its manufacture. On a long-barrel gun (e.g., a rifle
or shotgun), if an accessory front sight is required, attaching
such accessory front sight on one side or both of a front tower
sight construction (e.g., on an M-16 style rifle) is one preferred
position. Alternatively, such an accessory front sight could be
affixed to the barrel, to a barrel-insulating device or to an
accessory rail that is attached to the barrel portion 121 or the
receiver 118.
[0040] The single-mirror target viewing apparatus 116 includes a
mirror assembly 122 and a mounting base 124. The mirror assembly
122 is fixedly (i.e., non-rotating and non-pivoting) to the
mounting base 124 and includes a single utilized mirror 126 that
define a target imaging surface (e.g., reflective surface of the
single utilized mirror). Preferably, the single utilized mirror 126
is essentially flat. The mounting base 124 is attached to the
mounting rail 120 of the gun body 112.
[0041] When in the use position U, the target imaging surface of
the single utilized mirror 126 is in a skewed orientation with
respect to a longitudinal axis of the barrel portion 121 of the gun
100. In this orientation, a desired target and means for indicating
when the target is acquired in an aimed manner may be viewed on the
target imaging surface with the gun held in a partially rotated
position (i.e., rotated along its longitudinal axis to a position
between about the 12 o'clock position and about the 3 o'clock or 9
o'clock positions). Accordingly, single-mirror target viewing
apparatus 116 enables a shooter to view on the target imaging
surface both the desired target and the means for visually
indicating when the gun is aimed at a desired target, thereby
enabling the gun to be to accurately fired from a cover position in
an aimed manner.
[0042] Guns configured with target viewing apparatuses in
accordance with the inventive disclosures made herein are used in
conjunction with a target acquisition apparatus to facilitate
accurately shooting from a cover position (e.g., around a corner)
with minimal or no exposure of the shooter's body. Such target
viewing apparatuses are positioned generally in line with and
behind an associated target acquisition apparatus. Such target
viewing apparatuses include a single utilized mirror that may be
adjustable to allow for tilting the gun at different horizontal
angles (i.e. laid over on its side relative to the shooter). It is
preferable for the mirror to be positioned so as to require the
shooter to lay the gun at a minimum of approximately 45 degrees
from vertical in order to use a wall or other obstacle to protect
as much of the shooter's hand as possible. For left-handed shooting
(i.e., the right side of the gun exposed to the shooter) on guns
with a right side ejection port, it is preferred that the mirror be
positioned so as to require that the gun be laid over to a degree
where cartridges will not be ejected into the shooter's face.
[0043] Use of target viewing apparatuses in accordance with the
inventive disclosures made herein in conjunction with handguns to
facilitate accurately shooting from a cover position is
contemplated. Generally, the underlying configuration discussed
above in reference to long barrel guns also applies to handguns. In
one embodiment specific to handguns, the target viewing apparatus
and an opto-electrical target acquisition apparatus are mounted
beneath the barrel of the handgun. Accordingly, the shooter can
accurately aim and shoot around a corner by utilizing the mirror to
acquire the target and to aim. Preferably, adjustability of the
mirror is restricted so as to require the shooter to orient the gun
in a non-vertical orientation. The non-vertical position serves the
purpose of helping to protect the shooter's hand behind cover and
also protect the shooter's face from shells that are being ejected
out of the gun.
[0044] FIGS. 5-7 show a targeting system in accordance with the
present invention, which is referred to herein as the targeting
system 200. The targeting system 200 includes a mounting rail 202,
a single-mirror target viewing apparatus 204, a target acquisition
apparatus 206 and a mirror shrouding apparatus 208. The
single-mirror target viewing apparatus 204, the target acquisition
apparatus 206 and the mirror shrouding apparatus 208 are fixedly
mounted on the mounting rail 202. The mounting rail 202 is of a
standard configuration (e.g., industry standardized) for being
attached to a receiver or other portion of a gun and for having
accessory items mounted thereon. Alternatively, the mounting rail
202 may be integrally formed with the receiver or other portion of
a gun.
[0045] The single-mirror target viewing apparatus 204 is mounted
adjacent a first end portion 210 of the mounting rail 202 and the
target acquisition apparatus 206 is mounted adjacent a second end
portion 212 of the mounting rail 202. In this mounted
configuration, the single-mirror target viewing apparatus 204 is in
spaced-apart relationship with the target acquisition apparatus 206
with respect to a longitudinal axis L1 of the mounting rail 202.
The mirror shrouding apparatus 208 extends from adjacent the
single-mirror target viewing apparatus 204 toward the first end
portion of the mounting rail 202.
[0046] The target acquisition apparatus 206 includes means for
visually indicating when a gun on which the targeting system 200 is
mounted is aimed at a desired target. Examples of the target
acquisition apparatus 206 include optical sight apparatuses,
opto-electical sight apparatuses, and conventional mechanical sight
apparatuses. An optical scope is an example of an optical sight
apparatus. Trijicon brand, Docter Optic brand and EOTech brand
target acquisition apparatuses are examples of opto-electical sight
apparatuses that utilize laser, holographic, LED reflection and/or
optical technologies. Examples of conventional mechanical sights
include mechanical sights provided on a gun by its original
equipment manufacturer and accessory mechanical sights configured
for being attached to the gun after its manufacture. On a
long-barrel gun (e.g., a rifle or shotgun), if an accessory front
sight is required, attaching such accessory front sight on one side
or both of a front tower sight construction (e.g., on an M-16 style
rifle) is one preferred position. Alternatively, such an accessory
front sight could be affixed to the barrel, to a barrel-insulating
device or to an accessory rail that is attached to a barrel portion
or a receiver potion of the gun.
[0047] The single-mirror target viewing apparatus 204 includes a
mirror assembly 214 and a mounting base 216. The mirror assembly
214 is movably attached to the mounting base 216. The mirror
assembly 214 includes a single utilized mirror 218 (FIG. 7) that
defines a target imaging surface (e.g., exposed reflective surface
of the single utilized mirror 218). Preferably, but not
necessarily, the single utilized mirror 218 is essentially flat.
The mounting base 216 is attached to the mounting rail 202 by a
clamping structure 219 (FIG. 5).
[0048] The mirror assembly 214 is moveably attached to the mounting
base 216 in a manner enabling the mirror assembly 214 to be pivoted
between a plurality of positions with respect to the mounting base
216 and to be rotated between a plurality of rotational positions
with respect to the mounting base 216. In this manner, the single
utilized mirror 218 (i.e., in combination with the mirror assembly
214) is movable between a stowed position S (FIG. 5), a mirror use
position U (FIG. 7) and a sighting device use position U2 (FIG. 6).
The stowed position S and the a sighting device use position U2 are
both examples of mirror non-use positions in accordance with the
present invention.
[0049] As discussed below in greater detail, when the single
utilized mirror 218 is in the mirror use position U, the
single-mirror target viewing apparatus 204 enables a shooter to
view on the target imaging surface of the single utilized mirror
218 both a desired target and the means for visually indicating
that the gun is aimed at a desired target. As is discussed below in
greater detail, when the single utilized mirror 218 is in the
sighting device use position U2, a sighting device attached to the
mirror assembly 214 is in a respective use position.
[0050] Preferably, an axis of rotation of the mirror assembly 214
and/or the single utilized mirror 218 with respect to the mounting
base 216 extends through a central region of the single utilized
mirror 218. As disclosed above, the single utilized mirror 218
defines a target imaging surface, which as shown in FIG. 7 is
within the central region of the single utilized mirror 218. Thus,
in at least one embodiment of the present invention, the axis of
rotation A1 (FIG. 7) of the single utilized mirror 218 extends
through the target imaging surface of the single utilized mirror
218 when the single utilized mirror 218 in the mirror use position
U. In this manner, the target imaging surface of the single
utilized mirror 218 is skewed with respect to the axis of rotation
A1 of the single utilized mirror 218 when the single utilized
mirror 218 is in the mirror use position U. Accordingly, the axis
of rotation A1 of the single utilized mirror 218 extends through
the target imaging surface of the single utilized mirror 218 at a
single point when the single utilized mirror 218 is in the mirror
use position U and is skewed with respect to the longitudinal axis
L1 of the mounting rail 202. Preferably, but not necessarily, the
target imaging surface of the single utilized mirror 218 is skewed
with respect to the axis of rotation A1 of the single utilized
mirror 218 throughout an entire range of rotation of the single
utilized mirror 218. It should be understood that the mirror use
position U depicted in FIG. 7 is one example of a rotated position,
which so happens to corresponding to a particular mirror use
position of the mirror assembly 214. Preferably, but not
necessarily, the mirror assembly 214 is rotatable a fully 360
degrees or, at least a substantial portion thereof.
[0051] Preferably, the mirror assembly 214 is positively positioned
(i.e., selectively securable) in the stowed position S, the
sighting device use position U2 and the mirror use position U. To
this end, a first positive positioning structure is provided
between the mirror assembly 214 and the mounting base 216 and a
second positive positioning structure is provided between the
single utilized mirror 218 and a base attachment portion 220 (FIG.
5) of the mirror assembly 214. The positive position structures
jointly enable the single utilized mirror 218 to be positively
positioned in a plurality of predefined positions. The mirror use
position U, the sighing device use position U2 and the stowed
position S are examples of such predefined positions.
[0052] In one embodiment, the positive positioning structures each
include a locating member than engages a mating feature for
facilitating such positive positioning. With respect to the first
positive positioning structure, an example of such a structure
includes a spring loaded element of the mounting base 216 that
selectively engages each one of a plurality of mating feature of
the base attachment portion 220 for providing positive positioning
of the mirror assembly 214 with respect to the mounting base 216.
The plurality of mating features (e.g., detent features) are
provided in spaced apart relationship with respect to each other
for enabling positive positioning of the base attachment portion
220 at positions corresponding to the mirror use position U, the
sighting device use position U2 and the stowed position S. It is
disclosed herein that the relative association of the locating
member and a mating feature with the mounting base 216 and the base
attachment portion 220 may be reversed while still providing
positive positioning functionality. With respect to the second
positive positioning structure, an example of such a structure
includes a spring loaded element of the base attachment portion 220
that selectively engages each one of a plurality of mating feature
of a mirror casing 222 of the single utilized mirror 218 for
providing positive positioning of the single utilized mirror 218
with respect to the base attachment portion 220. The plurality of
mating features (e.g., detent features) are provided in spaced
apart relationship with respect to each other for enabling positive
positioning of the mirror assembly 214 at positions corresponding
to the mirror use position U, the sighting device use position U2
and the stowed position S. It is disclosed herein that the relative
association of the locating member and a mating feature with the
base attachment portion 220 and the mirror assembly 218 may be
reversed while still providing positive positioning
functionality.
[0053] Referring now, to FIGS. 8-10, the single-mirror target
viewing apparatus 204 includes a sighting device 224 attached to a
rear surface of the mirror casing 222. The single utilized mirror
218 is attached to a front surface of the mirror casing 222, which
is opposite the rear surface. The sighting device 224 includes an
alignment member 226 having two sighting structures. The alignment
member 226 is pivotably mounted on a windage adjustment screw 227.
A first sighting structure 228 is angularly offset from a second
sighting structure 230 with respect to longitudinal axis L3 of the
pivot member the windage adjustment screw 227 whereby pivoting of
the alignment member about the longitudinal axis L2 of the windage
adjustment screw 227 allows each one of the sighting structures
(228, 230) to be moved to a sighting structure use position U2. A
positive positioning structure is provided between the alignment
member 226 and the mirror casing 222 for enabling each one of the
sighting structures (228, 230) to be selectively and positively
positioned in the sighting structure use position U2.
[0054] The first sighting structure 228 includes a first aperture
229 (i.e., a first sighting feature) having a first diametrical
size. The second sighting structure 230 includes a second aperture
231 (i.e., a second sighting feature) having a second diametrical
size different than the first diametrical size. The depicted
apertures (229, 231) are examples of two different sighting
features. In addition to the sighting features in accordance with
the present invention being different size, it is disclosed herein
that such sighting features can be shapes, relative positioning
with respect to the longitudinal axis L2 of the windage adjustment
screw 227, etc.
[0055] When the single-mirror target viewing apparatus 204 is
properly attached to a gun and when a sighting feature of the
alignment member 226 is in the sighting structure use position U2,
that sighting feature is alignable with a mating alignment member
of a companion sighting device (e.g., a front sight of the gun)
when the single utilized mirror is in the sighting device used
position U2. Such alignment provides for precision aiming of the
gun through combined use of the sighting device 224 and the
companion sighting device.
[0056] The alignment member 226 is mounted in a manner enabling
independent adjustment for windage and for elevation. Adjustment
for windage refers to lateral adjustment of the alignment member
226 along to the longitudinal axis 2 of the windage adjustment
screw 227. Adjustment for elevation refers to vertical adjustment
of the alignment member 226 along a vertical reference axis V1
extending through the longitudinal axis L2 of the windage
adjustment screw 227.
[0057] For enabling windage adjustment, the windage adjustment
screw 227 is mounted on a support member 232 whereby rotation of
the windage adjustment screw 227 causes lateral translation of the
windage adjustment screw 227 (i.e., along the longitudinal axis
L2). The alignment member 226 is mounted on the windage adjustment
screw 227 in a manner that enables pivoting of the alignment member
226 relative to the windage adjustment screw 227 and that
substantially precludes lateral movement of the alignment member
226 with respect to the windage adjustment screw 227. Thus, lateral
translation of the windage adjustment screw 227 results in a
corresponding lateral translation of the alignment member 226.
[0058] For enabling elevation adjustment, the support member 232 is
mounted on the mirror casing 222 in a manner enabling the support
member 232 to be pivoted about a longitudinal axis L3 of a pivot
member 234. The longitudinal axis L3 of the pivot member 234
extends parallel to the longitudinal axis L2 of the windage
adjustment screw 227. An elevation adjustment screw 236 is engaged
between the support member 232 and the mirror casing 222. Rotation
of the elevation adjustment screw 236 causes the support member 232
to pivot correspondingly about the longitudinal axis L3 of the
pivot member 234, thereby resulting in vertical movement of the
alignment member 226 along a vertical reference axis V1.
[0059] Referring to FIG. 10, accuracy of aiming with the sighting
device 224 requires repeatable and precise repositioning of the
single utilized mirror 218 in the sighting device use position U2.
Once the alignment member 226 is adjusted for windage and elevation
with respect to companion sighing device, the degree of precision
to which the single utilized mirror 218 can be repositioned in the
sighting device use position U2 largely impacts accuracy in aiming.
To thus end, a locking structure is provided between the mounting
base 216 and the mirror assembly 214 for enabling the mirror
assembly 214 to be fixedly retained in the sighting device use
position U2 (i.e., a non-use position relative to a position in
which the mirror assembly 214 is used). The locking structure
includes a locking member 238 movably attached to the mounting base
216 and a slot 240 in the mirror casing 222 (i.e., a mating
engagement feature fixedly attached to the mirror assembly 214).
The locking member 238 is selectively movable between an engaged
position E (i.e., within the slot 240) and a disengaged position D
(i.e., removed from the slot 240). The locking member 238 is
captured within the slot 240 (i.e., engages the mating engagement
feature) when moved to the engaged position E while the mirror
assembly 214 is in the sighting device use position U2, thereby
jointly constrains movement of the single utilized mirror 218 with
respect to the base attachment portion 220 and the mounting base
216. Additionally, the locking member 238 and the slot 240 are
jointly configured (e.g., size, shape material, etc) whereby
engagement of the locking member 238 within the slot 240 provides
for precision repositioning (i.e., also referred to as zeroing) of
the mirror assembly 214 in the sighting device use position U2.
[0060] Referring to FIGS. 5, 6, 11 and 12, the mirror shrouding
apparatus 208 includes a mirror shrouding body 242 having an
attachment region 244 engagable with the mounting rail 202 for
enabling the mirror shrouding body 242 to be attached to a mating
structure of a gun (e.g., an receiver, a barrel cover, integral
mounting rail, etc) or an accessory item (e.g., a single-mirror
target viewing apparatus 204 in accordance with the present
invention). It is disclosed herein that the attachment region 244
may alternatively be configured for being engaged with the mating
structure of a gun or the accessory item. It is further disclosed
herein that the attachment region 244 may include an integral
retention device (e.g., set screw or clamp arrangement) that
secures the mirror shrouding apparatus 208 in place on the mounting
rail 202 or may include an interlock feature that engages a mating
interlock feature of the single-mirror target viewing apparatus 204
such that securing the mirror shrouding apparatus 208 in place on
the mounting rail 202 via the clamping structure 245 (FIG. 8) of
the mounting base 216 correspondingly secures the mirror shrouding
apparatus 208 in place on the mounting rail 202.
[0061] When the mirror assembly 214 is in the stowed position S
(FIG. 5) or the sighting device use position U2 (FIG. 6), the
position, size and/or shape of the mirror shrouding body 242 with
respect to that of the mirror assembly 214 serves to preclude all
beams of light reflected by the target imaging surface from being
visible at any remote location relative to the single-mirror target
viewing apparatus 204 with the single-mirror target viewing
apparatus 204 in any orientation (i.e., with the single-mirror
target viewing apparatus 204 staying in a fixed position with
respect to the mirror shrouding apparatus 208). In effect, the
mirror shrouding body blocks all reflected beams of light after the
beams of light impinge upon the target imaging surface of the
single utilized mirror 218. In providing such functionality, the
mirror shrouding body 242 precludes beams of light from impinging
upon the target imaging surface of the single utilized mirror 218
and/or blocks a reflected portion of the beams of light after the
beams of light impinge upon the target imaging surface of the
single utilized mirror 218.
[0062] The mirror shrouding body 242 includes a mirror casing
receiving recess 246 (FIGS. 6 and 11). The mirror casing receiving
recess 246 has disposed therein at least a portion of the mirror
casing 222 of the single-mirror target viewing apparatus 204 when
the single utilized mirror 218 is in the stowed position (i.e., a
non-use position with respect to use of the single utilized mirror
218). The mirror casing receiving recess 246 advantageously permits
spacing between the mirror shrouding body 242 and the single
utilized mirror 218 to be maintained at a minimum distance when the
single utilized mirror 218 is in the stowed position S and the
sighting device use position U2.
[0063] Referring now to FIGS. 13 and 14, the mirror shrouding body
242 includes upstanding members 248 and an upper edge portion 251
of the mirror casing 222 includes upstanding member receiving
recesses 250 therein. The upstanding members 248 engage the
upstanding member receiving recesses 250 when the single utilized
mirror 218 is in the stowed position S. When engaged, the
upstanding members 248 and the upstanding member receiving recesses
250 jointly carry a load resulting from an externally applied force
exerted on the mirror casing 222 thereby limiting deflection of the
mirror casing in the downward and/or lateral directions. In doing
so, the upstanding members 248 and the upstanding member receiving
recesses 250 jointly reduce the potential for the externally
applied force resulting in damage to the mirror assembly 214. It is
disclosed herein that the upstanding member receiving recesses 250
may be provided in another region of the mirror casing 222 as
opposed to the upper edge portion 251 of the mirror casing 222
(e.g., side edge portions).
[0064] Still referring to FIGS. 13 and 14, the mirror casing 222
includes a mounting rail receiving recess 252 in the upper edge
portion edge 251. The mounting rail receiving recess 252 engages
the top face of the mounting rail 204 when the single utilized
mirror 218 is in the stowed position S. When engaged, the mounting
rail receiving recess 252 and the mounting rail jointly carry a
load resulting from an externally applied force exerted on the
mirror casing 222 thereby limiting deflection of the mirror casing
in the downward and lateral directions. In doing so, mounting rail
receiving recess 252 and the mounting rail jointly reduce the
potential for the externally applied force resulting in damage to
the mirror assembly 214.
