Description
RELATED APPLICATIONS
[0001] This, application claims the benefit of U.S. application
Ser. No. 16,133,369 filed Sep. 17, 2018 which is a provisional of
U.S. application Ser. No. 62/558,922 filed on Sep. 15, 2017 and
which is incorporated herein by reference.
FIELD OF THE INVENTION
[0002] This invention is directed to telescopic gun sights and a
reticle pattern suitable for long-range shooting. The reticle
provides an improved grid pattern that allows for a rapid target
acquisition using the grid layout which can be utilized in combat
situations with minimal needs to perform calculations that are
necessary for prior art reticle designs. Further, the reticle
allows target adjustments to be made without mechanical adjustments
to the gun sight.
BACKGROUND OF THE INVENTION
[0003] The present invention relates to telescopic gun sights, and
more particularly to reticles for use in telescopic gun sights.
[0004] The accuracy and consistency in shooting depends largely
upon the skill the shooter and the construction of the fire arm and
quality of ammunition.
[0005] At very long ranges, environmental conditions and laws of
physics can affect the flight of the bullet and the point of impact
down range. Once such factor is "bullet drop" caused by the
influence of gravity on the moving bullet. To adjust for bullet
drop, it is necessary to elevate the barrel of the weapon and the
aiming point to adjust for bullet drop. Other factors such as wind,
the magnus effect, bullet design, and various unique properties of
the weapon can cause the bullet to drift to the left or right of a
central path over long range. Such effects are generally referred
to as "windage" effects. Therefore, to hit a target at long range,
it may be necessary to correct for windage by moving the barrel of
the weapon slightly to the left or right to compensate for bullet
drift. Thus, in order to hit the target at long range, the shooter
must see the target, accurately estimate the range to the target,
estimate the effect of bullet drop, any wind factors, and process
this information to properly position of the barrel the firearm
prior to squeezing the trigger.
[0006] Conventional telescopic gun sights or scopes are not
generally useful at long ranges. The cross hairs of such scope are
typically located in the center of the field and modifications to
this basic system have not, thus far, enabled a skilled shooter
firing at long ranges to acquire and hit a target quickly and
reliably. According, there remains room for variation and
improvement within the art.

although such apparatus or process is labeled with the same
reference numbers.
[0035] European Patent EP 1038149B1, U.S. Pat. Nos. 8,365,455,
5,920,995, and 7,343,707 are all incorporated herein by reference
in their entirety and provide teachings which include the
construction of optical sights, reticles, and the use of reticles
in acquiring a target which compensate for wind, bullet drop, and
other environmental conditions such as ambient temperature,
humidity, and surface reflected radiation/convection.
[0036] An improved reticle for an optical sight is provided which
facilitates the rapid acquisition of a target that allows for
correction of lateral drift as well as compensating for vertical
bullet drop. The reticle design as set forth herein provides for an
improved grid system that allows for rapid target acquisition. A
fully enabling disclosure to one of ordinary skill in the art is
further provided by the Figures, the written specification
including the references incorporated therein by reference, and the
claims of the present application.
[0037] As set forth in FIG. 1 a first embodiment of a reticle
according to the present invention is shown. The reticle 10
comprises a horizontal cross hair 12, a vertical cross hair 14,
which intersect at a location 16 that is typically used to "zero
in" a specified target at a known distance. As further seen in
reference to FIG. 1, below the horizontal line 12 there extends a
series of additional vertical lines 20 on either side of reticle
line 14 and extending downwardly from the horizontal line 12. In
the example shown, there are a series of five vertical lines on
either side of the vertical line 14 and which further define a
plurality of tic marks in a specified known distance. As seen in
the figures, the left and right edges of horizontal line 12 can
have an increased thickness or height to help low light
visualization as does the upper portion of vertical line 14.
[0038] In the embodiment illustrated in FIG. 1, the grid pattern is
divided into tic marks of mil or milradian and 1/2 mil or milradian
increments. This particular reticle design maintains open areas
along the top, sides and bottom of the reticle pattern and
facilitates the instant hold for aiming and for trajectory
calculations for any bullet path. The top horizontal line has
similar markings 24 with additional ticks or markings 26 at
increments of 0.2, 0.4, 0.6, and 0.8 mil vertical spacing between
vertical lines 20.
[0039] The main vertical line 14 additionally has incremental tick
marks or lines 28 that allow for height of target adjustment to the
closest 1/10 mil to help in range determination. The mil formula is
typically used within military scopes. The mil formula is as
follows:
[0040] For a dedicated weapon system (DWS) using a standardized
caliber, barrel length, and specified ammunition such as a 7.62
millimeter or 5.56 millimeter or a 0.300 Windchester Magnum.RTM., a
ballistic bullet drop choke gauge 36 for width of E-target is
matched with the mil hold impact at each range and is fitted along
the central vertical cross hair. The left side of the observed
target is placed against the central vertical and a series of left
pointing chevrons are used to find width and when the chevron fits
at the right side of the observed target it gives one the correct
range and impact of the round at that same range at the same time.
The user then adjusts the center of the target on the main vertical
at center mass for that mil-hold for proper targeting and firing.
No charts are needed, no math, and no calculations.
[0041] In the embodiment as seen in FIG. 1, the 1 mil markings
reflect 3.6 at 100 yards or 3.9 inches at 100 meters.
[0042] As seen in FIG. 2, a similar reticle layout to that of FIG.
1 is provided with additional optional markings seen in the left
and right bottom quadrants, a range finder choke gauge that can
range from 2 to 12 can be set forth on respective opposite sides of
the main reticle pattern. This allows for rapid range finding using
the left side gauge 32 for height and the right side gauge 34 for
width.
[0043] One advantage of the reticle patterns as seen in the
embodiments of FIG. 1 and FIG. 2, as well as the additional
embodiments set forth below, is that the reticle pattern provides
the complete functional information needed for vertical and
horizontal sight adjustments yet does so in a pattern that avoids
too much clutter from excessive information, excessive number of
grid lines present in many prior art scopes. Additionally, as seen
in reference to FIG. 1 and FIG. 2, the upper region of the scope
above the horizontal line 12 is free of distracting grid lines with
respect to the left and the right sides of horizontal line 12. In
instances where the magnification of the scope is reduced, the
"collapse" of the reticle pattern into a smaller region of the
scope sight still provides for useful information and can be
discerned by the user. Many prior art reticle patterns are so
crowded that on low magnification, the reticle pattern completely
obscures the intended target.
[0044] As seen in reference to FIG. 3, an embodiment similar to
FIG. 2 is added which illustrates a torso 30 which represents a
known target dimension that allows for accurate placement and
adjustment of the reticle grid pattern to a desired target location
within the reticle.
[0045] As seen in reference to FIGS. 4A and 4B, a specific reticle
pattern portion is set forth which is directed to a customized
0.338 Lapua, at a 500 meter range with a 2.75 mil adjustment
vertically and a lateral wind adjustment of horizontal of 1.5 mils.
The indicated reticle pattern may be specific for the exact weapon,
barrel length, and ammunition to allow for greater precision and
accuracy by a marksman.
[0046] FIG. 5 is an alternative embodiment of a reticle pattern in
which the vertical and horizontal grid markings are set forth in a
4 minute of angle (MOA) pattern. Again, additional tick marks are
provided in a minimally obtrusive manner so as to preserve the
overall ability of the reticle in scope to provide for clarity of
vision even when the magnification of the scope may change. This is
particularly important with respect to battlefield conditions where
one may need to adjust quickly to enemy fire and be able to sight
through the scope motion or hostile forces. A crowded scope
environment tends to obscure the vision and can impair a shooter's
ability to respond to enemy fire or locations.
[0047] An additional embodiment of the invention as seen in
reference to FIGS. 6A and 6B showing additional and alternative
grid markings with respect to using a 5 minute of angle (MOA) grid
pattern. As seen in reference to FIG. 6B even when magnified, the
grid pattern allows for rapid adjustments and positioning of the
gun relative to, an acquired target with adjustments for vertical
drop and horizontal windage.
[0048] As seen in reference to FIGS. 7A and 7B a customized reticle
pattern in accordance to this invention is provided. As seen in
reference to FIG. 7A, a human shaped target silhouette 30 can be
provided in one or more locations within the reticle. The image 30
is of a known size at an equilibrated distance and allows for rapid
adjustments and sightings based upon distance and windage
calculations.
[0049] FIG. 7B illustrates a height gauge (50) and width gauge (52)
and aiming point 54 and which is ammunition specific.
[0050] As seen in reference to FIG. 7B, the difference in the
silhouette image 30 as seen in reference to various distances of
100, 200, 400, and 800 meters.
[0051] The optional bullet drop choke patterns on the left and
right lower quadrants are also provided. The particular reticle
pattern illustrated is designed for a 0.338 Lapua with a 7.62
millimeter bore diameter. It is equally possible to customize a
reticle pattern for other weapons such as a 5.56 mm (M16) or 7.62
mm (Nato).
[0052] The embodiments illustrated above are preferably used with a
front or first focal plane optical sight. The grid could also be
lowered to center filed of view instead of 5 mils above, with 5.56
mm and 7.62 mm weapons.
[0053] One advantage of the reticle system is that it allows both
short and long range shooting using an etched glass, decal, or,
projected, grid reticle without having to use a windage or
elevation adjustment knobs on the scope. By way of example, a scope
with the reticle pattern of the present invention, once zeroed in
to a point of aim, simplifies the calculation and use of mil-angle
grid units which may include units used for military purposes in
terms of minute of angle (MOA) units or units expressed in
mils.
[0054] The scope's adjustment knobs may be calibrated for either
system to use the grid system. For instance, one grid pattern can
have markings in 0.1 millimeters per click of adjustments in terms
of both lateral windage adjustments and vertical elevation
adjustments. In examples where the grid is expressed in MOA units,
the optical reticle pattern can be used with click adjustments for
windage and elevation in 1/4 MOA or 1/2 MOA per click. With the
rifle zeroed in at the main horizontal cross hair, the optical
center of view provides for 1/2 mil tick marks to allow for
descending movement down the reticle, as range increases, on the
main vertical and central cross hair. The grid is specifically
built to allow for wind drift effects at range by having vertical
lines, each one 1 mil apart, with 1/2 mil flags or cross hairs, in
the direction of the wind on both sides of the main vertical
reticle marker.
[0055] This arrangement allows for the mil cross hairs and mil tick
marks to provide for precise holds. The grid is specifically
designed to allow for wind drift effects on both sides of the main
reticle with the tick marks still remaining close to the optical
center without "bottoming out" in the lowest field of view.
[0056] The vertical grid with the wind direction marks provide 5
mils right to left which allows for rapid acquiring of a target due
to the elimination of stacked horizontal cross hairs as is commonly
used in conventional reticles. The "decluttering" of the reticle
view greatly opens up vision through the reticle, reducing the
obstruction of view of threats which might be located behind the
grid and obscured by the multitude of grid lines in certain prior
art designs. This is especially helpful at the lower power settings
on variable power scopes with a front focal plane reticle location.
The front focal location, being needed to range accurately at, any
power, will shrink in size and tighten the grid at lower power and,
correspondily, expands the grid at higher powers of magnification.
At lower power magnifications, the reticle described herein still
provides a very clean and open viewing pattern that can be utilized
and will not block or obscure needed details such as hostile
personnel or dangers that can be viewed in the background.
[0057] The grid also features an instant hold-awareness by having
the solid lines laying over the wind flags on the 5.sup.th,
10.sup.th and 15.sup.th mil positions and can extend every 5 mils
as needed. This feature reduces the chance of a wrong line hold by
seeing clearly the count and avoiding too much optical clutter and
tangle when wind hold-offs are needed or when panning the rifle
with respect to moving targets.
[0058] For precise mil-measuring of height and width of targets,
the respective tick marks are present at each end of the top main
horizontal cross hair (between the 5 mil long black bars) with tick
marks at 0.2, 0.4, 0.6 and 0.8 mils between the last outside mil
for width sizing, to the closest 0.1 mil for targets in the same
top mil, for closest 0.1 Mil of target height.
[0059] Once height and width are measured to the closest 0.1 mil,
the range to target can be determined by plugging into the mil
formula. The mil formula is as follows:
[0060] The known height or width of the target in meters or yards
can be multiplied by 1,000 and then divided by the mil size of the
target as seen in the scope. This value equals the range to target
in the appropriate units of measure.
[0061] One example in reference to the US Army's "E" target (head
to torso) is 1 meter high by 0.5 meters wide. The known height of 1
meter times 1,000 divided by the measured seen height of the target
through the scope. For example, 2.5 mils, equals a range of 400
meters times 1,000 divided by 2.5 or 1,000 divided by 2.5 equals
500 meters range.
[0062] Known width is 0.5 meters times 1,000 divided by the
measured seen width of the target through the scope, such as 1.25
mils, equals a range of 400 meters. The calculation of 0.5 times
1,000 divided by 1.25 or 500 divided by 1.25 equals a 400 meter
range.
[0063] Once this range of target is determined, the trajectory of
the particular bullet and bullet drop attributable to gravity for
400 meters is, for example 2.2 mils below the zero point, so for a
hold of center mass target at 2.2 mils, figuring a level shot with
no wind observed.
[0064] With a high number of hostile threats firing at multiple
ranges, the need to range and engage rapidly to reduce hostile
threats is vital. The E3LR Military RF has military range finders
added on each side of the grid body as best seen in reference to
the Figures. The left side scale wilt measure height of targets
from 200 meters to 1200 meters with bracketed size marked from 2 to
12 for a known 1 meter height target. The upward pointing chevrons
in between the brackets from to the top flat line measure 0.5 meter
height target, 1/2 height E-target (prone shooter).
[0065] The range finder (RF) scale on the right side of the grid
body measures the width of the target from 200 to 1200 meters in
reference to a known 0.5 meter target width, in this case E-target
width/
[0066] These RF scales greatly enhance the speed of range
determination by placing observed threats quickly in height scale
and width scale and then using the correct mil-hold over for that
range from the prior engagement position of the scope. There are
charts that can be utilized for the mil-hold for each range
recorded from prior shooting and such charts of mil-hold impacts
can be placed on a rifle stock of a weapon or made available on a
laminated card. This system allows for quick training and
understanding use of the reticle scope and rifle by non-sniper
personnel in using the range finder scales to range impact which
requires no formulas or calculations which can be an advantage in a
heavy multi-targeted attack in which multiple range shots are
needed with little time to do calculations as required by other
conventional reticle formats.
[0067] For a dedicated weapon system using a standard caliber,
barrel length, and specified ammunition, a ballistic drop choke
drop gauge for width of target be matched with the mil-hold at each
range and is fitted along the central vertical cross hair. The left
side of the observed target is placed against the central vertical
and a series of left pointing chevrons are used to find width when
the chevron fits at the right-side of the observed target. This
arrangement gives you the correct range and impact at that range
simultaneously. Accordingly, the user merely needs to place a
center of the target on the main vertical at center mass for that
mil-hold without having to refer to charts or perform any
mathematical calculations.
[0068] Full capability of the reticle allows for an increased
reaction in terms of ranging and engagement of any new targets.
This is particularly useful when a scope is matched to a particular
caliber rifle, length of rifle barrel and tied to specific
ammunition. For any given caliber weapon, the reticle allows for an
improved grid system that provides for more rapid determination of
a firing solution for the range determined. The reticle, tied to a
specific rifle, barrel, and ammunition combination allows for an
uncluttered field of view, rapid site adjustments to be made by the
sniper or spotter, and avoids a cluttered optical field that can
mask threats or have such a multitude of grid lines and content
that use of the reticle by a shooter is made more difficult.
