Abstract

An adjustable sight element in a sight system for a rifle and the like may comprise an aperture disc for a peep sight or an adjustable sight structure for a telescope sight. The adjustable sight element is adjustably mounted for movement about vertical axis and a horizontal axis in a stationary housing attached to the rifle. The magnitude or degree of the vertical and horizontal displacement of the adjustable sight element is indicated by a capacitance or optronic measuring device and is displayed digitally in electronic digital fields. The electronic component is located in a casing which is removably attached to the housing.

Claims

1. In a device for aligning an adjustable sight element in a sight system for rifles and the like, a housing having a vertical portion and adapted to be attached to a rifle, a vertically and horizontally adjustable sight element mounted on said housing, a printed circuit board electrode on said housing vertical portion and a second electrode on said adjustable sight element to define means responsive to the movement of said adjustable sight element, and digital read-out means connected to said movement responsive means for indicating visually the magnitudes of the horizontal adjustment and vertical adjustment of the adjustable sight element with respect to a predetermined zero setting.

2. In a device as claimed in claim 1, wherein said adjustable sight element comprises an aperture disc of a peep sight.

3. In a device as claimed in claim 1 wherein said printed circuit board is mounted on an inner surface of a plate covering a frontal surface of said housing.

4. In a device as claimed in claim 1 wherein said housing has a removable casing, said digital read-out means being disposed within said removable casing.

5. In a device as claimed in claim 1 wherein said digital read-out means comprises a pair of separate read-out screens, one of said screens being for horizontal movement and the other screen for vertical movement.

6. In a device as claimed in claim 1 wherein said digital read-out means comprises a single read-out screen, and means on said digital read-out means for selectively indicating one of said vertical movement and said horizontal movement on said screen.

7. In a device as claimed in claim 1 wherein said digital read-out means further comprises a battery and a memory circuit connected to said battery such that the last adjustable sight element setting is stored in the memory.

8. In a device as claimed in claim 7, and further comprising means for automatically switching off a power supply from said battery to said digital read-out means after a predetermined period of time.

9. In a device as claimed in claim 4 wherein said digital read-out means further comprises a battery and a memory circuit connected to said battery such that the last adjustable sight element setting is stored in the memory, said battery being disposed in said casing.

10. In a device as claimed in claim 1 wherein said electronic means is removable from the aligning device such that the user of the rifle is able to operate said device either mechanically or electronically.

11. In a device as claimed in claim 1 wherein said adjustable sight element comprises a telescope sight adjustably supported on said housing.

12. In a device as claimed in claim 1 wherein said adjustable sight element comprises a reticle of a telescope sight.

13. In a device as claimed in claim 1 wherein said adjustable sight element comprises an adjustable sight structure within a telescope sight fixedly mounted on the rifle.

14. In a device for aligning the reticle of a telescope sight on a rifle, a vertically and horizontally adjustable reticle for a telescope sight mounted on said housing, electronic means responsive to the displacement of said reticle, and digital read-out means connected to said electronic means for indicating visually the magnitudes of the horizontal movement and vertical movement of the reticle from a predetermined zero setting.

15. In a device for aligning an adjustable sight structure in a telescope sight fixedly mounted on a rifle and the like, a housing adapted to be attached to a rifle, said telescope sight having at least a portion thereof within said housing and having an adjustable sight structure therein, electronic means responsive to the adjusting movement of said sight structure, and digital read-out means on said housing and connected to said electronic means for indicating visually the magnitude of the vertical adjustment of said adjustable sight structure with respect to a predetermined zero setting.

16. In a device as claimed in claim 15 wherein said digital read-out means indicates visually the magnitudes of both the horizontal movement and vertical adjustment of said adjustable sight structure with respect to a predetermined zero setting.
