Abstract

A telescopic sight for firearms has a laser rangefinder for the target with a laser transmitter and a laser receiver. Since the beam path of the laser transmitter and the beam path of the laser receiver are brought into the visual telescopic sight beam path, the telescopic sight objective is simultaneously the objective for the laser transmitter and the laser receiver. For adjusting the reticle on the point of impact an optical member movable relative to the weapon is provided between the reticle and the light entrance side of the telescopic sight.

Claims

1. A telescopic sight for firearms comprising:

a reticle (4), a device for adjusting the reticle on a point of impact and a laser rangefinder for the target with a laser transmitter (18) and a laser receiver (21), wherein a telescopic sight objective (8) is simultaneously the objective for the laser transmitter (18) and the laser receiver (21) since the beam path (17) of the laser transmitter (18) and the beam path (20) of the laser receiver (21) are brought into a visual telescopic sight beam path (9), and the device for adjusting the reticle (4) on the point of impact including an optical member movable relative to the firearm between the reticle (4) and the light entrance side (38) of the telescopic sight.

2. The telescopic sight of claim 1, wherein the beam path (17) of the laser transmitter (18) and the beam path (20) of the laser receiver (21) are brought into the visual telescopic sight beam path (9) between the objective (8) and the reticle (4).

3. The telescopic sight of claim 2, wherein for bringing the beam path (17) of the laser transmitter (18) and the beam path (20) of the laser receiver (21) into the visual telescopic sight beam path (9), the telescopic sight further includes a reflection surface (15, 16) selectively reflecting the light and passing visible light is disposed in the visual telescopic sight beam path (9) in each case.

4. The telescopic sight of claim 1, wherein for bringing the beam path (17) of the laser transmitter (18) and the beam path (20) of the laser receiver (21) into the visual telescopic sight beam path (9) the telescopic sight further includes a reflection surface (15, 16) selectively reflecting the light and passing visible light is disposed in the visual telescopic sight beam path (9) in each case.

5. The telescopic sight of claim 4, wherein the two reflection surfaces (15, 16) are disposed one behind the other in the visual telescopic sight beam path (9).

6. The telescopic sight of claim 4, wherein the beam path (17) of the laser transmitter (18) and the beam path (20) of the laser receiver (21) are brought into the visual telescopic sight beam path (9) coaxially.

7. The telescopic sight of claim 1, wherein the beam path (17) of the laser transmitter (18) and the beam path (20) of the laser receiver (21) are brought into the visual telescopic sight beam path (9) coaxially.

8. The telescopic sight of claim 7, wherein two reflection surfaces (15, 16) are disposed one behind the other in the visual telescopic sight beam path (9).

9. The telescopic sight of claim 1, wherein the optical member of the adjusting device movable relative to the firearm is formed to include at least one partial lens of the objective (8).

10. The telescopic sight of claim 9, further including two adjusting spindles (39) disposed at an angle to each others, provided for moving the at least one partial lens of the objective (8).

11. The telescopic sight of claim 10, further including a component carrier (2) disposed in an outer tube (1) of the telescopic sight provided for holding in place the laser transmitter (18) and laser receiver (21), control and evaluation electronics of the laser rangefinder as well as an erecting system and an eyepiece (6) of the telescopic sight.

12. The telescopic sight of claim 1, further including an optical distance display (22) connected to evaluation electronics of the laser rangefinder and adapted to be brought into the visual telescopic sight beam path (9).

13. The telescopic sight of claim 12 wherein the optical distance display (22) emits light in the long-wave of visible light, and a reflection surface (14) selectively reflecting the light of the optical distance display (22) is provided for bringing the optical distance display (22) into the visual telescopic sight beam path (9).

14. The telescopic sight of claim 13, further including a component carrier (2) disposed in an outer tube (1) of the telescopic sight provided for receiving the laser transmitter (18) and laser receiver (21), control and evaluation electronics of the laser rangefinder as well as an erecting system and an eyepiece (6) of the telescopic sight.

15. The telescopic sight of claim 14, further including a memory, disposed on boards (27-29), provided in which the ballistic data of the weapon and the ammunition are storable, and the device for adjusting the reticle (4) is operable by at least one servomotor (44'"'"') which is controllable by the evaluation electronics of the laser rangefinder and the ballistic data stored in the memory.

16. The telescopic sight of claim 1, further including a component carrier (2) disposed in an outer tube (1) of the telescopic sight provided for holding in place the laser transmitter (18) and laser receiver (21), control and evaluation electronics of the laser rangefinder as well as an erecting system and an eyepiece (6) of the telescopic sight.

17. The telescopic sight of claim 16, wherein the electronics of the laser rangefinder is disposed on boards (27 to 30), the component carrier (2) has a prismatic cross section, and the boards (27 to 30) are disposed on the outside surface of the component carrier (2).

18. The telescopic sight of claim 17, wherein the component carrier (2) has a coaxial duct (3) for receiving the erecting system.

19. The telescopic sight of claim 16, wherein the component carrier (2) has a coaxial duct (3) for receiving the erecting system.

20. The telescopic sight of claim 1, further including a memory, disposed on boards (27-29), provided in which the ballistic data of the weapon and the ammunition are storable, and the device for adjusting the reticle (4) is operable by at least one servomotor (44'"'"') which is controllable by evaluation electronics of the laser rangefinder and the ballistic data stored in the memory.
