Telescopic sight

The invention relates to a telescopic sight for particular hand-held firearms.

This particular after assembly of the telescopic sight on the gun, the target point with the meeting in accordance can be accommodated in the known riflescopes the target mark generally in the focal plane of the disposed objective and of the eyepiece relative to the main pipe supported the riflescope movable and with two perpendicularly arranged adjusting spindles adjustable (See. DE 32 08 814 C2).

Also of adjusted riflescope fall due to the trajectory of the projectile to the target point and meeting place but only in removing together on the shot gun is. With a shorter distance than the Einschußentfernung is the meeting point of contrast with the target point and at a higher lower.

Although the hunter or other user knows mostly in a sufficient level for practical ballistic Services of the weapon and the bullet used and therefore the amount of deviation between a meeting point and destination point depending on the size of the deviation of the actual Shot distance from Einschießentfernung. It However prepares particularly in foreign, unfamiliar terrain often considerable difficulties, the actual distance to estimate with sufficient accuracy to the target. estimation error more than twice are not uncommon.

For precise distance measurement therefore be for hunting already Laserentfernungsmeßgeräte used (company brochure: Laser Rangefinder RF1, Swarovski Optik KG). Laser rangefinder based on the principle of transit time measurement a laser pulse or a laser pulse sequence, which is emitted from the laser transmitter. The laser pulse or the pulse train is reflected by the intended target. A portion of this reflected light hits the laser receiver. The resulting received signal stops Runtime measurement. Half of this time, divided by the constant speed of light, gives the distance the targeted goal.

The same disadvantages, the outside in a housing of the telescopic sight mounted laser distance measuring device according to DE 42 18 118 A1.

The exhibit Laserentfernungsmeßgeräte used nowadays separate for the laser transmitter and the laser receiver Beam paths with separate lenses. They are therefore bulky and heavy. Also, it is impractical, the goal in to do is point the shot twice, once with nämich the target of the laser distance measuring device to the to determine the shooting distance, and then by the reticle of the telescopic sight.

The object of the invention is therefore, a riflescope with integrated laser rangefinder already noted.

This is achieved according to the invention that the riflescope lens by introducing the beam path of the laser transmitter and the beam path of the laser receiver in the visual telescopic sight beam path while the lens forms for the laser transmitter and the laser receiver, and that the device for adjusting the reticle on the meeting a weapon against the movable optical part between the reticle and the light entrance side of the having riflescope.

According to the invention, the beam path of the laser transmitter is and the optical path of the laser receiver in the visual Beam path of the scope introduced. This provides the riflescope lens while the lens for the laser transmitter and the laser receiver. In order for a compact, weight-saving integration of the laser rangefinder realized in the riflescope.

The line of sight of the telescopic sight and the optical axis of its integrated laser rangefinder must accurately coincide, so that the laser rangefinder removal targeted to the target level of the telescopic sight Objective and not to adjacent the target object measures. On the other hand takes place the introduction of the beam path the laser transmitter and the laser receiver in the Beam path of the telescopic sight between the lens and reticle of the telescopic sight. D. h., When the adjustment of the Target on the meeting when zeroing the rifle would be effected by movement of the target, as with the known riflescopes, this would only line of sight adjusted to the target point, but not the optical Axis of the laser rangefinder, so that the laser rangefinder not the distance from the subject but measured target to an adjacent to the subject would.

To prevent this, has according to the invention, the device for adjusting the reticle to the meeting point with respect to the weapon movable optical part which between the reticle and the light entrance side of the Riflescope is arranged.

This compared to the weapon movable optical part of Jusitereinrichtung preferably by at least one Part of the objective lens is formed, but of course can also be the entire lens. In order to move the lens or part the entire lens, two, at a perpendicular angle be provided arranged mutually adjusting spindles.

It is also possible, that with respect to the gun lens movable portion form of disc which angle to each other having extending base surfaces, about the optical axis of the lens is rotatable and having a complementary Disc cooperates.

When adjusting the reticle to the meeting point at zeroing the weapon so that by moving the lens or objective part of the visual beam path of the telescopic sight and the optical path of the laser rangefinder adjusted together.

In the scope of the invention, the target is So preferably rigid relative to the outer tube, ie gun firmly disposed in contrast to most conventional Riflescopes.

For the introduction of the beam path of the laser transmitter and the Beam path of the laser receiver into the visual telescopic sight beam path is in each case a, the laser light selectively reflecting reflection surface in the visual telescopic sight beam path arranged. The reflection surface may are formed by a mirror or a prism.

For laser-selective reflection, the reflecting surface have a coating that absorbs long-wave laser light reflects about 0.9 microns with a wavelength of z. B., but the visible light passes.

The beam path of the laser transmitter and the optical path of the Laser receiver can coaxially into the visual telescopic sight beam path are introduced. The two reflective surfaces for the laser transmitter and laser receivers are optical axis of the lens then hinterinander arranged. If the reflecting surface of the laser transmitter then the objective side and the reflection surface for the laser receiver disposed goal mark each other, forming the laser receiver a coaxial to the optical axis of the lens Cone of rays in radiation coaxial conical surface of the laser receiver is arranged.

Instead of a coaxial arrangement of the visual beam path, the beam path of the laser transmitter and the beam path of the laser receiver, it is also possible to use the beam path the laser transmitter z. B. a, so for example, the lower half of the visual telescopic sight beam path einzuspiegeln, and the beam path of the laser receiver in the other, so for example, upper half of the visual Riflescope beam path.

The scope of the invention preferably further includes a digital display for by the laser rangefinder measured distance to the goal, which in the visual Riflescope beam is reflected. Is to a reflecting surface in the visual telescopic sight beam path angeordent, preferably between the Target one hand, and the two reflecting surfaces for the laser transmitter-receiver on the other.

In order for the digital or other optical distance display the view through the scope as little impaired, the visual indicator light may in the long wavelength The visible light region, for. Example, of more than 0.65 micron and send the reflection surface in the visual Riflescope beam path for reflecting the optical display comprise a coating containing a light of these Length shaft, thus reflected from 0.65 micron and more visible Light with an underlying length shaft, so a length wave of less than 0.65 .mu.m but lets through. Instead, the optical distance can be displayed in the visual telescopic sight beam path with a for sichbares Light is reflected partially transmissive reflecting face , whereby the optical display then a light with a wavelength of the entire visible range, ie z. B. white light, can emit, but what a may cause slight loss of brightness.

To simplify the assembly of the scope of the invention is preferably a component carrier provided which is inserted into the outer tube of the telescopic sight. Apart from the lens and the adjusting device can practically all other components of the scope of the be fixed component carrier, so z. B. the laser transmitter and the laser receiver with the entire optical system for reflecting the laser transmitter and the laser receiver in the visual Zielfernrohstrahlengang, the overall fiscal Evaluation electronics of the laser rangefinder, the optical Distance display with the optics for reflecting the optical distance display in the visual beam path of the scope and the reticle and the eyepiece of the Riflescope. This has the great advantage that all adjustment and inspection operations can be made before The assembly of the lens.

For the control and evaluation electronics of the laser rangefinder Sinkers are preferably provided, which at the Component carriers are arranged. For this purpose, the component carrier preferably a rectangular, in particular square Cross-section or other prismatic cross-section, for example a hexagonal cross-section, the boards on the outer surfaces of the prismatic Component carrier are arranged.

For holding the reticle, the inverting system and the eyepiece of the scope, the component carrier preferably a coaxial inner bore or a channel.

To the meeting point with the target point, depending on the the odometer measured target distance in bring conformity, it is known to the target to adjust on ballistic with a servomotor. In the embodiment according to claim 7 can therefore, for example, each of the two, mutually perpendicular adjusting spindles be operated with such an actuator. In order to in the control of the adjusting device or by the servomotors the ballistics of the gun and the received ammunition, is a storable with this information, electronic memory is provided, further comprising a computer which the signals of the evaluation electronics of the laser rangefinder associated with the stored data.
