Sighting device
The invention relates to a sighting device containing at least one self-luminous light source and at least one element made of a light-guiding and/or light-collecting material. Preferably, the self-luminous light source is embodied as a tube or ring and this light source is arranged in at least a portion of the length of the tube or ring, or along its entirety, and most preferably uses a tritium gas-containing element.
1. A sighting device containing at least one self-luminous light source and at least one element made of a light-guiding and/or light-collecting material, the element being embodied as a tube or ring having a first end-region, a second end-region and an internal cavity, the light source being received and positioned in an end-region inside the internal cavity of the tube or ring, wherein the light that penetrates into the tube through a lateral surface is collected and guided to the end surfaces, and wherein the light-collecting material is made of polymethacrylate into which are embedded molecules that fluoresce under the action of ambient light.
2. The sighting device according to claim 1 , wherein the exterior of the tube is uncovered.
3. The sighting device according to claim 1 , wherein the tube comprises, at least in portions, a casing made of a material that is opaque in the visible light region.
4. The sighting device according to claim 3 , wherein the casing is constituted from a tubular metal sleeve.
5. The sighting device according to claim 4 , wherein a transparent material is inserted into an end region of the metal sleeve.
6. The sighting device according to claim 3 , wherein the tube is closed off on a portion facing toward a user with a transparent material.
7. The sighting device according to claim 6 , wherein the transparent material is shaped as a lens or a converging lens.
8. The sighting device according to claim 7 , wherein the longitudinal extent of the light source is arranged transversely to a sighting direction.
9. The sighting device according to claim 8 , wherein the light source is embedded in a periphery of the tube or ring.
10. The sighting device according to claim 9 , wherein multiple rod-shaped light sources are arranged around a center axis of the tube or ring.
11. The sighting device according to claim 10 , wherein the light sources are arranged in the shape of a polygon or a rectangle around the center axis of the ring or tube.
12. The sighting device according to claim 1 , wherein at least one element made of a light-guiding and/or light collecting material is a lens or a converging lens and is arranged in the tube between the light source and a light exit side facing toward a user.
13. The sighting device according to claim 1 , wherein the light source radiates light at least radially with respect to its longitudinal extent.
14. The sighting device according to claim 1 , wherein the device comprises a rear sight and a front sight, the front sight comprising an elongated, self-luminous light source that is arranged coaxially with a tube made of a light-guiding or light-collecting material, and the rear sight comprising at least two self-luminous light sources, the front sight comprising a light source and a tube.
15. The sighting device according to claim 14 , wherein a housing surrounding at least a part of the lateral surface of the tube of the front sight is present, which housing is made of a transparent material that is different from the material of the tube.
16. The sighting device according to claim 14 , wherein the rear sight is a peep sight implemented as a ring, and wherein multiple rod-shaped self-luminous light sources are embedded in a periphery of the ring and arranged around a center axis of the ring.
17. The sighting device according to claim 14 , wherein the rear sight is embodied as a U-notch sight or V-notch sight, at least one light source being respectively arranged on either side of a U- or V-shaped depression of the rear sight.
18. The sighting device according to claim 17 , wherein the rear sight comprises, on both sides of the U- or V-shaped depression, a respective element made of a light-guiding or light-collecting material, which optionally comprises a light-incoupling region for collecting ambient light.
19. The sighting device according to claim 18 , wherein at least one of the light-guiding elements has a T-shaped cross section, the light source being arranged in a crosspiece of the T.
20. The sighting device according to claim 19 , wherein at least one of the light-guiding elements is of a cylindrical configuration or has rectangular base surface.
21. The sighting device according to claim 17 , wherein the longitudinal extent of the light sources of the rear sight extend transversely to a sighting direction.
