This invention relates generally to sighting devices and more particularly to sights used on projectile launching devices, optical devices and other suitable devices used to view a target. Iron sights are generally known in the art as a pair of physical aiming structures located a distance from one another. When positioned and aligned appropriately, these aiming structures help align a device with the target.
Traditional iron sights use a front sight having a central pin or indicator, which helps to align the device on the center of the target; however, because the pin extends to the center, it generally occludes a portion of the target. A drawback to traditional iron sighs is occlusion of the target by the sight structures. There remains a need for novel sighting structures that allow for fast target acquisition, better target visibility and added precision.

Referring to
In some embodiments, the first body 50 comprises an adjustment mechanism 19 arranged to move at least one portion 75, 77 of the first body 50 with respect to the base 53. In some embodiments, an adjustment mechanism 19 is arranged to move the first portion 75 and the second portion 77 simultaneously with respect to the base 53. In some embodiments, the adjustment mechanism 19 is arranged to move the first portion 75 and the second portion 77 in equal but opposite directions with respect to the base 53. In some embodiments, movement of the first portion 75 and second portion 77 is symmetrical across the center of the sight window 52. In some embodiments, the adjustment mechanism is engaged with a central portion of the base 53. In some embodiments, the adjustment mechanism 19 comprises a trapezoidal shape. In some embodiments, the adjustment mechanism comprises a wedge. In some embodiments, the base 53 comprises a raised flange, recessed channel or other engagement mechanism and the first portion 75 and second portion 77 are shaped to engage the base 53. In some embodiments, the first portion 75 and second portion 77 are slidably engaged with the base 53.
In some embodiments, the second body 60 comprises a base and one or more portions moveable with respect to the base, for example to adjust a width of the second sight window 62. In some embodiments, the second body 60 comprises an adjustment mechanism 19 as described herein with respect to the first body 50.
Various embodiments of an aiming apparatus 40 comprise sight windows 52, 62 having any suitable sizing relative to one another. In some embodiments, the first sight window 52 is wider than the second sight window 62. In some embodiments, the second sight window 62 is wider than the first sight window 52. In some embodiments, two variables can help to determine proper sight window sizing—a first distance between the first sight window 52 and the second sight window 62, and a second distance between the first sight window 52 and the user's viewpoint. In some embodiments, the first distance is relatively small compared to the second distance—for example when the device 8 is a pistol. For example, the first distance between the first sight window 52 and the second sight window 62 in a pistol may be in the range of 4″-6″ and the second distance is likely in the range of 10″-18″. When the second distance is larger than the first distance, it is often desirable to have the first sight window 52 wider than the second sight window 62. In some embodiments, the first distance is relatively large compared to the second distance—for example when the device 8 is a rifle. For example, the first distance between the first sight window 52 and the second sight window 62 in a rifle may be in the range of 8″-18″ and the second distance is likely in the range of 3″-6″. When the first distance is larger than the second distance, it is often desirable to have the second sight window 62 wider than the first sight window 52.
In some embodiments, a method comprises various steps of providing and/or using the first body 50 and second body 60 as described herein. In some embodiments, a method comprises viewing a target through a first sight window and a second sight window. In some embodiments, a method comprises adjusting a width of a sight window.
The above disclosure is intended to be illustrative and not exhaustive. This description will suggest many variations and alternatives to one of ordinary skill in this field of art. All these alternatives and variations are intended to be included within the scope of the claims where the term “comprising” means “including, but not limited to.” Those familiar with the art may recognize other equivalents to the specific embodiments described herein which equivalents are also intended to be encompassed by the claims.
Further, the particular features presented in the dependent claims can be combined with each other in other manners within the scope of the invention such that the invention should be recognized as also specifically directed to other embodiments having any other possible combination of the features of the dependent claims. For instance, for purposes of claim publication, any dependent claim which follows should be taken as alternatively written in a multiple dependent form from all prior claims which possess all antecedents referenced in such dependent claim if such multiple dependent format is an accepted format within the jurisdiction (e.g. each claim depending directly from claim 1 should be alternatively taken as depending from all previous claims). In jurisdictions where multiple dependent claim formats are restricted, the following dependent claims should each be also taken as alternatively written in each singly dependent claim format which creates a dependency from a prior antecedent-possessing claim other than the specific claim listed in such dependent claim below.
This completes the description of the preferred and alternate embodiments of the invention. Those skilled in the art may recognize other equivalents to the specific embodiment described herein which equivalents are intended to be encompassed by the claims attached hereto.
