The present invention relates to an apparatus for aiding in the alignment of a scope of a firearm.
The present invention provides an apparatus for aiding in the alignment of a scope of a firearm. The apparatus includes a light generation device and a level indicator. The light generation device is attachable to the firearm and generates a reference beam. The reference beam may be a horizontal, vertical, or cross-hair line beam. The apparatus is constructed so that when the level indicator indicates a level state, the reference beam generated by the light generation device is also level. Typically, the level reference beam is projected against a flat surface and is used as a reference to line up the crosshairs of a scope attached to the firearm.
The light generation device may include a bore connector and a light generator. The bore connector has two ends, one of which is attachable to the firearm. Typically, the bore connector is inserted into the bore of the firearm. The light generator is attached to the other end of the bore connector. The light generator generates the reference beam. Typically, the light generator will include a laser, but may be any type of light generator capable of producing a reference beam. The light generator may also include a reference beam lens. In this case, the reference beam is generated by passing light produced by the light generator through the reference beam lens.
The level indicator may be mounted on or in a housing that contains the reference beam lens. The level indicator and reference beam lens are situated in the housing such that a reference beam generated from light passing through the reference beam lens is level when the level indicator shows a level state. In order to coordinate the level indicator with the reference beam lens, the housing may contain a physical guide that controls the orientation of the lens when placed in the housing. In this way, a more repeatable and accurate orientation of the lens can be achieved.
It is to be understood that the descriptions of this invention herein are exemplary and explanatory only and are not restrictive of the invention as claimed.
Reference will now be made in detail to the present exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings.
The invention provides an apparatus for aiding in the alignment of a scope of a firearm. Typically, the apparatus is attachable to a firearm. The apparatus generates one or more visible reference beams and utilizes a level indicator to indicate when the reference beam is level. That is, if the level indicator indicates a level state, the reference beam will be level. The one or more level reference beams may then be used as an aid in leveling and/or aligning the scope of the firearm (e.g., an optical scope).
When apparatus 100 is activated, reference beam(s) 105 is projected against a surface. Preferably, reference beam(s) 105 is projected substantially along the longitudinal axis of the firearm barrel so as to simulate the flight path of a projectile. The apparatus is then adjusted so that the reference beam(s) is level. The structures and methods for producing a level reference beam(s) and verifying that the reference beam is level will be discussed in more detail with reference to
Level indicator 124 operates in conjunction with light generation device 110 such that when level indicator 124 indicates a level state, the reference beam(s) 105 generated by light generation device 110 is also level. A level state is defined as 0 degrees from a horizontal plane for a horizontal line-shaped reference beam and 90 degrees from the horizontal plane for a vertical line-shaped reference beam. Any type of level indicator may be employed. As shown in
Light generation device 110 may include a light generator 114 and a bore connector 112. Bore connector 112 preferably has two ends. First end 116 of the bore connector is insertable into bore 210 of firearm 200. It may be advantageous to utilize a bore adapter 130 to accommodate firearm bores of varying sizes. In this case, bore adapter 130 is inserted into firearm bore 210 and first end 116 is then inserted into the bore adapter. In addition, bore connector 112 may be inserted into a bore connector receptacle 135 that may be attached to the firearm. Once inserted into the firearm bore or bore connector receptacle, light generation device 110 should be able to rotate freely around the longitudinal axis of the firearm barrel.
Second end 117 of bore connector 112 is connected to light generator 114. Light generator 114 may be any device capable of generating a reference beam. In addition, light generator 114 may also be a light source that requires an additional lens to generate a reference beam. For instance, light generator 114 may be a laser that produces a reference beam by projecting laser light through an additional lens, such as reference beam lens 122. Such lasers are typically battery powered and activated with a switch 115. For example, light generator 114 may be a solid-state laser module. The combination of such a laser and a bore connector, without a reference beam lens, is often called a “Laser Bore Sighter.”
To make use of such Laser Bore Sighters, one embodiment of the invention provides a reference beam lens 122 contained within a housing 120. As discussed above, level indicator 124 may also be mounted on or in housing 120. In addition, housing 120 may be constructed to contain both reference beam lens 122 and level indicator 124 in common. Reference beam lens 122 and level indicator 124 are situated such that a reference beam generated by passing light through the reference beam lens (such as a laser beam from a Laser Bore Sighter) is level when the level indicator indicates a level state. Reference beam lens 122 may be any lens capable of producing a reference beam suitable as a reference for adjusting the scope of a firearm. Preferably, the reference beam lens is a line-generating lens.
Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and embodiments disclosed herein. Thus, the specification and examples are exemplary only, with the true scope and spirit of the invention set forth in the following claims and legal equivalents thereof.
