FIREARM SCOPE ALIGNMENT METHOD AND TOOL

Abstract

A firearm scope alignment tool and method of use. An alignment tool may have a guide component, which may be located at the buttstock end of a firearm, may have a light source component, which may be positioned on the distal side of a scope and oriented into the scope, and may have a lens component, which may be positioned on the proximal side of the scope. The lens and light source may magnify and project the reticle of the scope onto the guide component, which may allow the scope to be adjusted in order to position the reticle such that the vertical line of the reticle is parallel to the bisecting plane of the firearm, as indicated by the guide component.

Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority from U.S. Provisional Patent Application Ser. No. 62/477,018, filed Mar. 27, 2017, the entire contents of which are hereby incorporated by reference.

BACKGROUND

When using a rifle or other firearm with a scope, the scope must be properly aligned such that it is square with the rifle in order to allow a user to accurately target the rifle. Specifically, the vertical part of the crosshairs or reticle should be placed so that it is perfectly parallel to a bisecting plane of the rifle, and such that the horizontal line is placed normal to the bisecting plane.

Certain tools for alignment of a firearm scope exist. For example, U.S. Pat. No. 8,745,914, for a “Telescopic Sight Ring Mounts Alignment Tool,” discloses a scope eye-piece mounted alignment tool which a user can make use of by setting it in front of the scope, aligning it with the vertical reticle, and attaching it with an elastic band. The tool will have a pointer on the bottom. Then, the user may rotate the scope within the ring mounts, until the pointer points to the center line of the bore (or the center of the rifle, as the case may be).

However, there may be problems with using this tool and method. In particular, if the reticle is not in the center of the scope when the user adjusts it, the user will end up adjusting the scope so that the reticle is no longer square (i.e. such that the vertical line of the reticle is no longer parallel to the bisecting plane) by using such a method. This will cause further difficulties for the user.

Another example of an alignment tool is the WHEELER ENGINEERING PROFESSIONAL RETICLE LEVELING SYSTEM. This system includes two machined aluminum level housings calibrated to their integrated levels. To make use of the system, the user attaches the first level, the “barrel clamp level,” to the barrel of a firearm, and attaches the second, smaller “reference level” to a flat surface perpendicular to the vertical axis of the gun (such as the scope base, the bottom half of the ring, or another flat surface). The user then rotates the gun until the reference level is aligned. The user then adjusts a tuning adjustment knob on the barrel clamp level until its level is centered to match the reference level. At this point, the barrel clamp level is calibrated to the axis of the firearm. The scope is then installed loosely, with the reference level placed on top of the scope's turret cap, and the scope is rotated until the reference level is aligned with the barrel clamp level. The scope is then secured in place.

There are also problems with using this tool and its associated method. Specifically, because this tool makes use of bubble levels (one for the scope, and one for the firearm), use of this tool can be highly susceptible to human error. The user will have to accurately read the bubbles in the bubble levels (which can often be imprecise) and will have to hold both the rifle and the scope steady. In this case, human error can compound on itself, because both the rifle and the scope will have their own independent levels which are aligned against one another.

Another example of an alignment tool is the EXD ENGINEERING VERTICAL RETICLE instrument. This instrument incorporates a spirit level that may be used to center the scope of a firearm over the bore, and may show the “off vertical” position of a vertical crosshair.

To make use of the system, a user may first choose a vertical reference line which may be easily and clearly viewed through the scope (such as a door frame, or an object that has been deliberately set up as a reference such as a weight hanging from a vertical string). The user may then use the instrument to ensure that the firearm is held in a level position on sandbags or in a gun rest. The user may then loosen the screws of the scope rings so that the scope may be rotated within the rings, and loosen the thumb screw on the instrument slightly so that the barrel V-block and the scope V-block position settings of the instrument can be adjusted. The user may then place the instrument onto the barrel of the firearm aligned with the scope, such that the flat portion of the instrument (with the slot in the center) covers the eyepiece of the scope. The user may then slowly tilt the firearm slightly from side to side until the bubble is centered exactly between the calibration marks of the level vial of the instrument. The user may then view the vertical reference line they have chosen through the scope of the firearm, and in that way determine if the scope has been correctly aligned or if the scope needs to again be adjusted.

The problem with using this tool is that it relies on sighting a distant standard in order to properly align the scope of the firearm. If the user chooses an incorrect standard, or a standard that they think is correctly aligned but which is not correctly aligned, the user may improperly sight the firearm. (For example, suppose that the user hangs a small weight from a vertical string from the ceiling of their house in order to create a standard from which they can align their scope. Suppose also that there is an air vent provided in a location where exit air from a heater or air conditioner can push on the vertical string. The vertical string may be skewed to one side while the air vent is active, skewing the alignment of the scope.) The tool also requires the user to keep the gun level, which may be impractical in some instances.

Another example of a scope alignment tool is the ARISAKA DEFENSE OPTIC LEVELER. This tool is formed from a small rectangular base plate having a grooved section that extends from one side of the plate to the other, and an angular wedge that is configured to fit within the grooved section of the plate. The angular wedge is formed at a shallow angle (specifically around 11 degrees). The grooved section of the base plate is formed such that one end is located at a higher elevation than the other, with the difference between the two ends of the groove being such that the groove has a steeper angle than the angular wedge in the vertical direction.

To use the tool, the base plate is placed under the scope of a rifle, on the Picatinny rail (or, if possible, on the one-piece mount) of the rifle, such that the base plate sits just below the turret cluster of the scope, and such that the groove faces to the side of the plate. The wedge then is inserted into the groove from the side of the base plate, on the side of the groove having a lower depth. As the wedge engages the base plate, the top of the wedge rises upwards, contacting the turret cluster of the scope and automatically leveling it.

While this tool is small and quite simple, it can often be inadequate. For example, the tool essentially requires that the mount of the rifle extend for the entire length of the scope; optimally, this mount should be a Weaver-type or Picatinny-type rail. While the tool is advertised as being usable with some one-piece mounts, it may not be usable with all such mounts. The tool also requires that the reticle be at a perfect level inside the scope in order for the user to make use of the tool to properly position the scope; sometimes, this is not the case, meaning that in such instances (which may not be immediately clear) the tool may be of limited use.

Another example of a scope alignment tool is the BADGER ORDNANCE DEAD LEVEL reticle leveling device. The DEAD LEVEL tool is a small platform on which a section of Picatinny rail is mounted. The tool includes several adjustable thumb screws for leveling the device, and an integrated precision bubble level that the user can use to check the orientation of the platform.

To use the platform, a user must remove their scope from the rifle, with the scope mounts still attached (but with the scope loose in the mounts), and attach the scope mounts to the platform. The user may then check the level of the platform, and make the appropriate adjustments by using the precision thumbscrews. At that point, the user may look through the scope at a level surface, such as the top of a building, and tighten down their ring caps.

This platform has numerous problems similar to those discussed above. For example, as previously discussed, the platform has all the problems of imprecision that come from using a bubble level. The platform also, as discussed above, requires the reticle to be perfectly level in the scope (which, again, is not always the case) in order for the user to be able to use it to properly align the scope. However, this platform introduces an additional complication—namely, that the user must remove the scope from the platform and put it back on the rifle without misaligning it in any way—which can also be a source of error.

Lastly, there have been some attempts to develop a light-based scope alignment tool, mostly from hobbyists making use of improvised prototypes. One such example of this is the method for leveling a reticle described by Tony Kahn of KAHNTROL SOLUTIONS in a Feb. 8, 2015 posting, https://kahntrol.com/leveling-a-reticle/, archived at http://web.archive.org/web/20160318093947/https://kahntrol.com/leveling-a-reticle/.

In particular, Mr. Kahn describes hanging a piece of poster board with a plumb line (i.e. a hanging string) hanging in front of it. Mr. Kahn recommends making use of a fine plumb line. The rifle is then set in front of the poster board, in a cleaning rest or on bipods, such that the buttstock of the rifle is located next to the plumb line but does not touch it. The user then should use a standard hardware level to get the rifle as level as possible.

Mr. Kahn then recommends finding the brightest light possible and shining it into the objective end of the scope. The user should then focus the scope until a clear projected image is shown on the poster board. This then provides a clear view of what adjustments need to be made and allows the user to have both hands free to make them.

This idea also has certain downsides. For example, it requires the user to place their rifle on a level surface in order to check it against the plumb line; if the surface is not level, then the method will produce a flawed adjustment of the scope, as there is no guarantee that the user will be able to adjust the vertical part of the reticle such that it is placed parallel to a bisecting plane of the rifle and such that the horizontal line is placed normal to the bisecting plane if the user is adjusting their scope based entirely on something independent from the rifle. The method also requires adjusting the focus of the lens until a projected image appears, which may require significant adjustments to the scope that will then have to be reversed.

Aspects of the invention are disclosed in the following description and related drawings directed to specific embodiments of the invention. Alternate embodiments may be devised without departing from the spirit or the scope of the invention. Additionally, well-known elements of exemplary embodiments of the invention will not be described in detail or will be omitted so as not to obscure the relevant details of the invention. Further, to facilitate an understanding of the description discussion of several terms used herein follows.

As used herein, the word “exemplary” means “serving as an example, instance or illustration.” The embodiments described herein are not limiting, but rather are exemplary only. It should be understood that the described embodiments are not necessarily to be construed as preferred or advantageous over other embodiments. Moreover, the terms “embodiments of the invention”, “embodiments” or “invention” do not require that all embodiments of the invention include the discussed feature, advantage or mode of operation.

According to an exemplary embodiment, and referring generally to the Figures, various exemplary implementations of an alignment tool for a firearm scope or sight may be disclosed.

Turning now to exemplary FIG. 1A, FIG. 1A displays an exemplary embodiment of components and tools that may be used to implement a scope alignment tool 100. This may include, for example, a scope guide component 102, a screwdriver or other tool 104 configured to remove or loosen the buttstock plate screws of a rifle or other firearm, a lens component 106, and a light component 108.

In some exemplary embodiments, a scope guide component 102 may be formed from one or more guides. In one exemplary embodiment, a scope guide component 102 may be constructed from two projection posts, each being formed (with a desired degree of precision) so as to be straight, and each being formed from a material that resists deformation, such as aluminum or another metal. Projection posts may be sized to fit between the buttstock of the rifle and the buttstock plate; for example, according to an exemplary embodiment, projection posts may be approximately ⅜ of an inch thick and approximately one inch wide, though projection posts may also be sized to have other dimensions.

In an exemplary embodiment, in order to install the projection posts, a user may loosen one or more screws on the buttstock plate of the rifle (or other firearm), so as to add an amount of space between the buttstock and the buttstock plate. The user may then place the projection posts between the buttstock and the buttstock plate, within that space. In some embodiments, wherein the screws have been accurately aligned along the center line of the rifle, the user may be able to use the screws as guides to determine how the projection posts should be placed; in other embodiments, when the screws have not been accurately aligned, the user may adjust the projection posts from this position. The user may then tighten the screws of the buttstock plate in order to clamp the projection posts between the buttstock and the buttstock plate.

Alternatively, in some embodiments, a user may remove the buttstock plate entirely. In such an embodiment, the projection posts may be mounted on the end of the buttstock in such a manner as to not obstruct the screws of the buttstock plate. Once the projection posts have been placed, the user may replace the buttstock plate by screwing the screws back in.

Referring exemplary FIG. 1B, in another exemplary embodiment, the guide may be a single piece. According to an exemplary embodiment, in order to install the guide, the user may remove the buttstock plate entirely, add the single-piece guide over the buttstock, and replace the buttstock plate and buttstock screws. In some exemplary embodiments, a single-piece guide may have one or more screw holes through which the screws of the buttstock plate may be disposed, which may aid in keeping the single-piece guide fixed in place. Alternatively, in an exemplary embodiment, the single-piece guide may have a plurality of openings in one side that are designed to fit over the screws, such that the portion of the guide that mounts to the buttstock has an “E-shape” or “3-shape.” As shown in FIG. 1B, in an exemplary embodiment, the single piece guide 118 may have a slot 120 which is mounted between the buttstock and a buttstock plate. The slot 120 of the guide may be designed to fit over the screws between the buttstock and a buttstock plate so that the guide may be mounted easily.

Turning now to exemplary FIGS. 2A and 2B, FIGS. 2A and 2B may show an exemplary embodiment of a scope alignment tool guide component 102. In an exemplary embodiment, such a guide component may be disposed between the buttstock of a rifle 110 and the buttstock plate 112 of a rifle. The buttstock plate 112 may then be tightened to secure the guide component 102 as shown in FIG. 2B.

Turning now to exemplary FIG. 2C, an alternative view of a scope alignment tool guide component 102 may be shown.

Turning now to exemplary FIG. 2D, an exemplary embodiment of a scope alignment tool light component 108 may be shown. According to an exemplary embodiment, a scope alignment tool 100 may be provided with a separate light component 108, which may be disposed such that it projects light through the scope in the direction of the guide component 102. According to an exemplary embodiment, the light component may be, for example, a flashlight, or may be any other light source, as may be desired.

According to an exemplary embodiment, a light component 108 may be fitted or fittable to a scope, for example by one or more fittings disposed on the portion of the light source facing the scope (such as the rim of the flashlight). In an exemplary embodiment, a light component 108 may be fittable to the barrel or stock of a rifle, for example with one or more clamps. In an exemplary embodiment, a light component 108 may be fittable to a rail of a firearm ahead of the scope. In an exemplary embodiment, a light component 108 may be a freestanding device, or may be coupled to a stand or other freestanding device on which the rifle is rested or mounted.

Turning now to exemplary FIG. 3, FIG. 3 shows an exemplary embodiment of a guide component 102 having an illuminated area 114 projected thereon by the light component 108. The light component 108 may project light through the scope and onto the guide component 102 in an area large enough to be visible to a user. It should be noted that, in the exemplary embodiment of FIG. 3, the reticle of the scope is not visible in the illuminated area 114.

Turning now to exemplary FIG. 4A, FIG. 4A shows an exemplary embodiment of a scope alignment tool lens component 106. In an exemplary embodiment, a scope alignment tool lens component 106 may be provided in front of the eyepiece of the scope of the rifle in order to magnify the light passing through the scope, which may have the effect of improving the visibility of the scope reticle.

According to an exemplary embodiment, the scope alignment tool lens component 106 may be a positive lens. In some embodiments, any type of positive lens may be used; for example, in an exemplary embodiment, the scope alignment tool lens component 106 may be a Fresnel lens. In some embodiments, any type of lens material may be used; for example, in an exemplary embodiment, a scope alignment tool lens component 106 may be constructed from a plastic, a glass, or any other kind of transparent material.

In an exemplary embodiment, the scope alignment tool lens component 106 may be fitted to a scope or may be fittable to a scope; for example, according to an exemplary embodiment, the scope alignment tool lens component 106 may be disposed on the scope so that it can be quickly added or removed from the eyepiece area of the scope, or may be formed within a housing that may be coupled to the eyepiece area of the scope. In another exemplary embodiment, the scope alignment tool lens component 106 may be housed within a housing, which may be fittable to the eyepiece area of the scope. In an exemplary embodiment, the scope alignment tool lens component 106 may be housed within a stand-alone device, or may be a separate component; for example, in an exemplary embodiment, a scope alignment tool lens component 106 may be a handheld large-aperture lens.

Turning now to exemplary FIG. 4B, FIG. 4B displays an exemplary embodiment of a scope alignment tool lens component 106, which may be used by holding the scope alignment tool lens component 106 in front of the eyepiece of the scope. When projecting light through the scope, the scope alignment tool lens component 106 may magnify the light emanating from the eyepiece of the scope and project the light onto the guide component 102, which may also serve to magnify the reticle of the scope and make it visible on the projection surface.

Turning now to exemplary FIG. 5, FIG. 5 displays an exemplary embodiment of a scope alignment tool 100 having the light component 108 activated and the lens component 106 in the proper configuration. The reticle 116 may be magnified and projected onto the guide component 102. This may allow for alignment of the scope.

According to the embodiment shown in FIG. 5, the reticle 116 may be displayed in a position that indicates that the scope is misaligned. The user may be able to adjust the scope to bring the reticle 116 into a position that indicates that the scope is properly aligned; this position may be a position such that the vertical line of the reticle 116 is collinear (or approximately collinear) with the edge of the guide component 102.

Turning now to exemplary FIG. 6, FIG. 6 displays an exemplary embodiment of a scope alignment tool 100 after the scope has been adjusted into a correct position. As shown in FIG. 6, the vertical part of the reticle 116 is provided along the edge of the guide component 102, indicating that the vertical part of the reticle 116 is properly aligned, parallel to the bisecting plane of the rifle.

Turning now to exemplary FIG. 7, FIG. 7 displays an alternative exemplary embodiment of a scope alignment tool 200 having a different shape to that of the scope alignment tool 100. According to an exemplary embodiment, a scope alignment tool 200 may, instead of fitting between the buttstock and buttstock plate of a rifle 110, permit the buttstock of the rifle 110 to be positioned on or in the scope alignment tool 200. For example, according to an exemplary embodiment, a scope alignment tool 200 may have an upper bracket 206 and a lower bracket 204 between which the buttstock of the rifle 110 may be mounted. Alternatively, the scope alignment tool 200 may have, for example, a recessed portion in which the buttstock of the rifle 110 may rest, or may alternatively be coupled to the rifle 110, as may be desired.

According to an exemplary embodiment, the scope alignment tool 200 may additionally have a stand 202, which may allow the scope alignment tool 200 to stand free. scope alignment tool 200 may additionally have a guide component 208, which may be, for example, a guide line or a guide grid, or may be, for example, one or more vertically-disposed projection posts which may be similar to projection posts 102.

Turning now to exemplary FIG. 8, FIG. 8 displays an exemplary embodiment of a scope alignment tool 200. According to an exemplary embodiment, a scope alignment tool 200 may have a guide component 208 that may be a guide grid with one or more guide lines 212 disposed in a position such that at least one of the guide lines 212 may be (and may be indicated to be) disposed along the center line of the rifle 110.

Turning now to exemplary FIG. 9, FIG. 9 displays an exemplary embodiment of a scope alignment tool 200 after a light component has been activated. An illuminated area 210 may be projected onto the guide component 208 from the eyepiece area.

Turning now to exemplary FIG. 10, FIG. 10 displays an exemplary embodiment of a scope alignment tool 200 after a light component has been activated and after a lens component has been properly positioned. The reticle 214 of the scope may be projected onto the guide component 208, allowing the scope to be adjusted to a position in which the reticle 214 is aligned in the proper position on the guide component 208.

Turning now to exemplary FIG. 11, FIG. 11 displays an exemplary embodiment of a scope alignment tool 200 after the scope has been adjusted into a correct position. The reticle 214 may be projected in a position such that it overlaps with the guide line 212, indicating that the reticle 214 is properly positioned.

Turning now to exemplary FIG. 12, FIG. 12 displays an exemplary flowchart of a method of using a scope alignment tool 300. In a first step 302, a user may configure the guide component of the scope alignment tool such that the guide component of the scope alignment tool supports the buttstock (whether by being coupled between the buttstock and buttstock plate, supporting the buttstock in a bracket, or any other such configuration, as may be desired). In a next step 304, a user may position a light source on the distal part of the scope such that the light source projects light through the scope in the direction of the guide component. In a next step 306, a user may position a lens or other magnifying implement on the proximal side of the scope, such that it magnifies and projects the reticle onto the guide component. In a next step 308, a user may align the reticle with a guide on the guide component.

Turning now to exemplary FIG. 13, FIG. 13 may show another exemplary embodiment of a single piece of a guide component. According to an exemplary embodiment, the single piece guide 118 may have a slot 120 which is mounted between the buttstock and a buttstock plate as described above in FIG. 1B. Also, in an exemplary embodiment, the dotted lines 216 may serve as a simple proof that the inside edges of the opening are parallel to the scribed center line 218 for the test of whether the scope alignment tool is manufactured accurately. Further, in an exemplary embodiment, the hash marks 212 on the cross lines may serve as a way to align the reticle parallel to the scribed center line 218 or dotted lines 216, and as marks for measuring deflection when the scope ring is tightened down after alignment.
