Rifle scope targeting display adapter mount
View Patent ↗This disclosure describes a compact and lightweight rifle scope display adapter configured to be affixed in front of the objective lens of a rifle scope. The display adapter includes a receptacle that enables the adapter to be electrically connected to a ballistic computer, rangefinder or other targeting mechanism. The display adapter is configured to receive aimpoint information and project illuminated symbology that is brought into focus by the rifle scope optics in such a way that the symbology appears to overlay an image of a scene on which the rifle scope is focused. The adapter includes a mounting assembly that provides two attachment mechanisms. A first ring of the RDA can be screwed into the threads on the interior surface of the scope. Additionally, the scope can be inserted into a second ring of the RDA and provides compressive, radial pressure against the outside surface of the scope.
1. An assembly for securely mounting a rifle scope display adapter (RDA) onto a scope body, the scope body having a threaded interior surface and an external surface, the assembly comprising:
a first ring configured to be coupled to the RDA and the scope body, wherein:
the first ring comprises a threaded exterior surface that is configured to mate with the threaded interior surface of the scope body; and
the first ring is configured to be coupled to the RDA such that the first ring can rotate around a center axis of the first ring; and
a second ring configured to be coupled to the RDA and scope body, wherein:
the second ring is configured such that the external surface of the scope body fits within the second ring; and
second ring is configured to cause radial pressure to be exerted against the external surface of the scope body.
2. The assembly of claim 1 , wherein:
the RDA comprises at least one optical component; and
the first ring is configured to be coupled to the RDA such that the first ring can rotate around a center axis of the first ring independent from rotation of the at least one optical component of the RDA.
3. The assembly of claim 1 , wherein the second ring comprises a collet having an interdigitated pattern.
4. The assembly of claim 1 , wherein the second ring comprises an outer ring with a flange and a threaded surface, the flange having substantially a same inside diameter as an outside diameter of the scope body.
5. The assembly of claim 4 , wherein the flange is configured to exert force against a collet as the threaded surface of the second ring is mated with a corresponding threaded surface.
6. The assembly of claim 5 , further comprising a third ring with a sloped surface that translates the force exerted against the collet by the flange into the radial pressure to be exerted against the external surface of the scope body.
7. The assembly of claim 1 , wherein the first ring is configured to position the RDA flush with a front surface of the scope body when the threaded exterior surface of the first ring is mated with the threaded interior surface of the scope body, such that at least one optical component of the RDA is perpendicular to a radial axis of the scope body.
8. The assembly of claim 1 , further comprising a spacer ring, the spacer ring comprising:
a first portion configured to mate with a uniform threaded internal surface of the RDA; and
a second portion configured to accommodate scope bodies of varying diameters.
9. The assembly of claim 1 , wherein the second ring is configured to be coupled to the RDA through one or more additional assembly components.
10. The assembly of claim 1 , wherein the radial pressure exerted against the external surface of the scope body prevents the RDA from rotating relative to the scope body.
11. A method for securely mounting a rifle scope display adapter (RDA) onto a scope body, the scope body having a threaded interior surface and an external surface, the method comprising:
coupling a first ring to the RDA and the scope body, wherein:
the first ring comprises a threaded exterior surface that is configured to mate with the threaded interior surface of the scope body; and
the first ring is configured to be coupled to the RDA such that the first ring can rotate around a center axis of the first ring; and
coupling a second ring to the RDA and scope body, wherein:
the second ring is configured such that the external surface of the scope body fits within the second ring; and
second ring is configured to cause radial pressure to be exerted against the external surface of the scope body.
12. The method of claim 11 , wherein:
the RDA comprises at least one optical component; and
the first ring is configured to be coupled to the RDA such that the first ring can rotate around a center axis of the first ring independent from rotation of the at least one optical component of the RDA.
13. The method of claim 11 , wherein the second ring comprises a collet with an interdigitated pattern.
14. The method of claim 11 , wherein the second ring comprises an outer ring with a flange and a threaded surface, the flange having substantially a same inside diameter as an outside diameter of the scope body.
15. The method of claim 14 , wherein the flange is configured to exert force against a collet as the threaded surface of the second ring is mated with a corresponding threaded surface.
16. The method of claim 15 , further comprising providing a third ring with a sloped surface that translates the force exerted against the collet by the flange into the radial pressure to be exerted against the external surface of the scope body.
17. The method of claim 11 , wherein the first ring is configured to position the RDA flush with a front surface of the scope body when the threaded exterior surface of the first ring is mated with the threaded interior surface of the scope body, such that at least one optical component of the RDA is perpendicular to a radial axis of the scope body.
18. The method of claim 11 , further comprising providing a spacer ring, the spacer ring comprising:
a first portion configured to mate with a uniform threaded internal surface of the RDA; and
a second portion configured to accommodate scope bodies of varying diameters.
19. The method of claim 11 , wherein the second ring is configured to be coupled to the RDA through one or more additional assembly components.
20. The method of claim 11 , wherein the radial pressure exerted against the external surface of the scope body prevents the RDA from rotating relative to the scope body.
