Abstract
An aiming device for guns, which comprises a transparent plate that shows to the user a critical image when the plate has a predetermined orientation, and shows a deformed image when said plate has any other different orientation. The transparent plate is so mounted in the device and the device is so mounted on the gun, such that the critical image is seen by the user when and only when the axis of the gun barrel is parallel to the line of sight passing through the user's eye and the center of the transparent plate.
Claims26
Aiming device for guns, which comprises one or more tubular elements supported by a gun barrel for displaying a critical image, each of said one or more tubular elements having—
- i. a tube configured with a bore having an inner diameter ranging from 3 to 10 mm;
- ii. a distally disposed light collecting rod housed within a sleeve made of solid transparent material and attached to said tube;
- iii. an annular, proximally disposed end of said tube, through which a user views an image projected from said rod and configured with a diameter substantially equal to that of said tube;
- iv. a lens mounted in a tube interior for projecting an image from said rod essentially throughout said proximally disposed end, wherein the distance between a rod proximal end and said lens is substantially equal to the focal length of said lens;
- and
- v. a characteristic tube length between said lens and said proximally disposed end of said tube which is greater than twice the focal length of said lens,
- a critical image appearing essentially throughout said proximally disposed end of said tube when said one or more tubular elements has a predetermined orientation such that the axis of the gun barrel is parallel to the line of sight passing through an eye of the user and a center of said lens,
- a deformed image appearing in said proximally disposed end of said tube when said one or more tubular elements has an orientation other than said predetermined orientation and the image projected from said lens is partially obstructed by a wall of, or enclosing, said tube, the relative location of said deformed image with respect to said proximally disposed end of said tube being indicative of the direction of deviation of the line of sight from the gun barrel axis,
- wherein a predetermined transition sharpness from said deformed image to said critical image is defined by said tube inner diameter and said characteristic length.

Aiming method for guns, comprising the steps of:
- a) providing a gun with one or more tubular elements supported by a gun barrel, each of said one or more tubular elements having—
- i. a tube configured with a bore having an inner diameter ranging from 3 to 10 mm;
- ii. a distally disposed light collecting rod housed within a sleeve made of solid transparent material and attached to said tube;
- iii. an annular, proximally disposed end of said tube, through which light exits and a user views an image projected from said rod and configured with a diameter substantially equal to that of said tube;
- iv. a lens mounted in a tube interior for projecting an image from said rod essentially throughout said proximally disposed end of said tube, wherein the distance between a rod proximal end and said lens is substantially equal to the focal length of said lens;
- v. a characteristic tube length between said lens and said proximally disposed end of said tube which is greater than twice the focal length of said lens and defines a predetermined critical image transition sharpness;
- b) aiming the gun at a selected target until said selected target surrounds said one or more tubular elements whereby a critical image appears essentially throughout said proximally disposed end of said tube when said one or more tubular elements has a predetermined orientation such that the axis of the gun barrel is parallel to the line of sight passing through an eye of the user and a center of said lens, and a deformed image appears in said proximally disposed end of said tube when said one or more tubular elements has an orientation other than said predetermined orientation and the object projected from said lens is partially obstructed by a wall of, or enclosing, said or more tubular elements;
- and
- if said projected image is a distorted image, changing the orientation of said one or more tubular elements by displacing said barrel until said critical image appears essentially throughout in said proximally disposed end of said tube.
