Description

Night vision attachment mountable on a firearm for a sighting telescope

Technical Field

The invention relates to a night vision attachment mountable on a firearm for a sighting telescope according to the preamble of claim 1.

Background

A night vision attachment mountable on a firearm for a sighting telescope is attached in front of the sighting telescope for night operation, which sighting telescope is also fixed on the firearm in a known manner. Since, in the usual case, only low-intensity light radiation is available during night operation, sighting telescope optical systems in the form of photopic optical systems cannot be used for observation. The attachment has night vision optics that can accept and amplify low intensity radiation, so by connecting the attachment in front of the sighting telescope, night operation of the sighting telescope can be allowed; for example: the attachment and the sighting telescope are connected to one another by mounting them on the weapon in an inserted or screwed manner. In this context, the term "night time" should not be understood to refer to a period of time, but to a situation where the irradiation conditions do not allow observation using a typical photopic system. A night vision attachment connected in front of the sighting telescope has a large, common type of objective to receive as much radiation as possible, and a low-light amplifier to amplify the radiation. The radiation received by the firmly attached night vision objective and subsequently amplified in the low-light amplifier is then projected through the eyepiece of the night vision attachment onto the objective of the sighting telescope, from which the radiation emerging can reach the marksman to form an image after passing through the conventional telescope optical system. In daytime operation, the night vision attachment is removed again, but the sighting telescope is used in such a way that it remains in the mounted position on the firearm, in order to avoid detuning the arrangement or orientation associated with the weapon.

Sighting telescope is mainly used for military purposes, and is mounted on firearms, especially guns, for aiming targets. As mentioned above, for night operation, a night vision attachment is attached in front of the sighting telescope and is also mounted on the firearm. Sighting telescope and night vision attachment are used in particular for sniper guns. The marksman's gun has a length of, for example, more than 1 meter overall and a barrel length of about 0.7 meter. For this gun, very high accelerations occur when shooting. The energy of the rearward movement of the weapon components, recoil, is absorbed by the inertia of the weapon and the marksman.

When the night vision aid and/or the sighting telescope are mounted on the firearm in an unstable manner, for example too high, the recoil caused by the translational and rotational momentum of the bullet will result in an unbalance of the sighting system, and parts of the system may fall out. This poses a safety risk to the marksman. The camouflaged marksman, if he had to do something, such as operating a night vision attachment, would be at risk, so that he could be positioned by an enemy. In the case of a night vision attachment arranged in front of the sighting telescope, which is outside the range in which the marksman can easily operate, the marksman must therefore perform a noticeable action if he wants to activate the operating device of the night vision attachment.

In order to keep the arrangement and orientation of the sighting telescope and the night vision attachment on the firearm as stable as possible, they are usually mounted by means of special forms of rail or bayonet connection. Slight directional errors during installation can result in the optical axis of the sighting telescope and the optical axis of the night vision attachment being skewed with respect to the central axis of the barrel of the firearm. In order to withstand the forces involved during the shooting process and, furthermore, in order to make it easier for the marksman to handle the firearm with the optical aid, a mounting which is as stable as possible is required.

For example, the action of the marksman often requires him to remain in the same position for several hours with the gun in the shooting position and the sighting telescope close to the marksman's eye. In order to make it easier for the marksman to maintain this position, it is appropriate to arrange the telescope as close as possible to the weapon. If the sighting telescope is mounted in an elevated position, the marksman must "neck" for a long time to observe and aim. Due to this inconvenient posture, on the one hand the safety of the marksman who must be kept as far as possible from being positioned by enemies is jeopardized and, on the other hand, the unnatural posture also endangers the health of the marksman. The elevated arrangement also compromises the stability of the arrangement.

Known rails or bayonet connections can support the scope over its entire length and allow it to be fixed as close to the gun body as possible. However, such arrangement and fixation become problematic when considered in connection with night vision attachments. Due to the aforementioned light intensity, the night vision objective of the night vision attachment is formed larger than the photopic objective of the sighting telescope. For example, the objective of a night vision attachment has a diameter of approximately 80mm, while the objective of a sighting telescope has a diameter of approximately 40 mm. Therefore, the sizes of the housings (the housing of the night vision attachment and the housing of the sighting telescope) surrounding the respective optical systems are different. Due to the aforementioned differences in dimensions, the optical axis of the sighting telescope is offset in height relative to the optical axis of the attachment, so that radiation emerging from the attachment substantially along the optical axis of the attachment is not on said optical axis of the sighting telescope. This coupling arrangement is therefore very complex, especially in view of stability.

In the known arrangement, in order to compensate for the dimensional differences, the sighting telescope is mounted in an elevated position so that its optical axis coincides with the optical axis of the night vision attachment connected in front, which optical axis is higher due to the larger objective of the attachment. Yet another alternative arrangement is to mount the night vision attachment on the sighting telescope so that the sighting telescope can be mounted as close (low) as possible to the firearm. The radiation received by the attachment is then reflected by the periscope-type optical system into the objective of the sighting telescope. However, this arrangement of increased height is unbalanced, especially when subjected to recoil from a shot, and is an inconvenient system for the marksman. The attachment may even fall off due to the impact forces affecting this arrangement. Furthermore, this arrangement therefore has a large parallax, for example 7-10cm, which the marksman has to additionally take into account as a correction factor when carrying out the ballistic calculation. Furthermore, this high arrangement would also endanger the camouflage of the marksman.

Disclosure of Invention

It is an object of the invention to provide a night vision attachment mountable on a firearm for a sighting telescope, wherein the attachment is formed in such a way that it can be attached in front of the sighting telescope while still allowing a stable arrangement of the sighting telescope with the attachment attached in front on the firearm.

Another object is to provide a night vision attachment mountable on a firearm for a sighting telescope with improved handling characteristics and operability.

These objects are achieved by the features of claim 1 or the dependent claims, or by further developed solutions.

According to the invention, a night vision attachment for a sighting telescope is formed in such a way that: so that an axial offset of the radiation entering the objective of the attachment, which is an offset in the direction of the optical axis of the sighting telescope downstream of the attachment, is achieved in the attachment itself. Due to the offset in the direction of the optical axis of the radiation, in particular of the sighting telescope or of the sighting telescope objective, within the night vision attachment itself, it is possible to arrange the night vision attachment and the sighting telescope such that the bottom of their respective housings are mounted virtually directly on the same support surface, for example a slide rail, and thus to mount the entire arrangement as close as possible to the housing of the firearm, in particular of a hand-held or hand-held firearm. A very stable system is thus provided which allows the marksman to maintain a more comfortable operating position.

By arranging as close as possible to the weapon housing, a more comfortable operating posture is made possible. The result of the radiation shift in the attachment is that radiation is directed in the attachment onto an optical axis substantially corresponding to the optical axis of the sighting telescope. The attachment can thus be attached directly in front of the sighting telescope and be fixed in such a way that the bottom of the attachment and the bottom of the sighting telescope, which is defined as the side to be mounted on the weapon, are situated substantially on the same horizontal plane. In this way, neither a raised mounting of the sighting telescope to align its optical radiation receiving axis with the optical radiation exit axis of the night vision attachment nor a periscope-like reflective arrangement to reflect the night vision radiation into the sighting telescope is required. Since the radiation emerging from the attachment is already substantially on the optical axis (radiation receiving axis) of the sighting telescope objective, the sighting telescope objective can directly receive said radiation in collimated form.

The prescribed scope includes a telescope that can be mounted on a firearm and is formed to aim a target to reliably shoot the target. For aiming, the sighting telescope usually has a crosshair which is adjustable in the lateral direction and in height. By suitable adjustment and firing of the weapon, the marksman can determine the operating parameters of the sighting telescope and of the firearm, which enable the marksman to hit the target in a controlled manner. In order to keep the adjustment time as small as possible, the arrangement of the sighting telescope mounted on the weapon for daytime operation is preserved when performing nighttime operation. Night vision attachment is mounted on the front of the firearm during night operation and is removed from the firearm during day operation. The arrangement on the firearm is chosen as close as possible to the weapon housing, especially for stability reasons. In this arrangement, the attachment or attachment housing is arranged substantially directly in front of the sighting telescope or sighting telescope housing, so that the radiation emerging from the attachment can be received by the sighting telescope without passing through any intermediate optical elements. With the specified 1 × zoom factor of the attachment, the precise angular position between attachment and sighting telescope, i.e. the attachment and sighting telescope are parallel to one another, is not difficult to achieve, so that the sighting line or the accuracy of the shot at night is not adversely affected.

Advantageously, the sighting telescope and the night vision attachment are formed such that they can be connected in a simple manner by means of a latch, "snap" or screw thread or the like.

The optical arrangement of the night vision attachment according to the invention comprises: a night vision attachment objective; a radiation amplifier; an optical component for radiation deflection, which advantageously also serves as an image reversal system; and a night vision attachment eyepiece. However, the night vision attachment can also have further optical elements, for example for guidance and/or correction of the light path.

The scope is designed in a conventional manner. It has a collimator objective, for example 40mm to 50mm in diameter, for receiving the radiation. It further has a telescope eyepiece through which the marksman or observer can observe the image formed by the received radiation. Furthermore, the sighting telescope generally also has at least one crosshair as mentioned above.

In night operation, the night vision attachment is connected in front of the sighting telescope. The radiation emitted by the object or scene is concentrated on the objective of the night vision attachment and amplified at the radiation amplifier. When using a low-light amplifier as radiation amplifier, the objective of the night vision attachment focuses the radiation on the entrance window of the amplifier. In a low-light amplifier, the radiation is electronically amplified and displayed as a brighter visible image on the exit window of the amplifier. The magnified image radiation is projected onto the objective of the sighting telescope by means of the eyepiece of the night vision attachment and then passes through the objective of the sighting telescope and through the optical elements of the sighting telescope to the observer.

In the night vision attachment according to the invention, the radiation received by the attachment objective travels along a first axis to the optical components in the attachment. By means of the optical assembly, the radiation is guided from a first axis, which substantially corresponds to the optical axis of the attachment objective, onto a second axis, which is substantially parallel to the first axis. The parallel second axis substantially corresponds to the optical axis of the eyepiece of the night vision attachment and thus also to the optical axis of the sighting telescope.

A beam offset of 25mm or more of the radiation travelling substantially along the optical axis of the night vision attachment objective, which is approximately 80mm in diameter, can be achieved, for example, by means of a suitably formed optical component, for example a porro (total internal reflection) prism system of a second type, which has a diameter of approximately 80mm, and which, if the sighting telescope and the bottom of the housing of the night vision attachment are at the same level, can receive radiation offset in the manner described above, for example substantially along the optical axis of a 40mm sighting telescope objective. In particular, the formation and arrangement of the optical components are selected such that the radiation received by the attachment objective travels as high a proportion as possible to the attachment eyepiece and then further into the sighting telescope. In particular, by the formation according to the invention, it is possible to transfer to the eyepiece of the telescope the amount of light that makes it possible to substantially completely illuminate the exit pupil of the eyepiece of the telescope. This facilitates the positioning of the eye at the eyepiece. In contrast, in known systems in which only a small area of the exit pupil is illuminated, a precise positioning of the eye is required to identify the image.

An optical component for the axial offset of the radiation is arranged, for example, between the radiation amplifier and the eyepiece of the night vision attachment. Advantageously, the assembly is additionally formed as an image reversal system. By configuring the optical assembly as an image reversal system, the quality of the image can be further improved, since for example a non-reversing image amplification tube can be used as a radiation amplifier. On the other hand, if the inversion of the image is performed in the amplifier as is conventional, a poor quality image is often obtained, because, for example, the optical fiber elements are used in the amplifier, and the resolution is reduced through the optical fiber window.

According to the invention, a prism or a lens system is used as the optical component. By using the second type of Porro prism, beam shifting and image inversion can be achieved simultaneously.

The night vision attachment according to the invention in combination with the sighting telescope is particularly suitable for use with assault rifles and with the above-mentioned sniper guns. Thanks to the structure according to the invention, it is possible to mount the night vision attachment and the sighting telescope close to the shell of the firearm, which makes the system more compact, more convenient and more stable. With the night vision attachment according to the invention, a marksman using a sighting telescope with a night vision attachment on a firearm can be provided with an arrangement which is particularly improved with regard to convenience and safety.

To further improve the operability of the night vision attachment of the sighting telescope, the invention also comprises the provision of at least one first and/or second mechanical switching device/operating device for the night vision attachment for safe operation by the marksman. The first or second mechanical switching device is connected with the first or second electronic switching device in the night vision attachment either wired or wirelessly. By means of which the setting of the night vision attachment can be changed in a known manner; for example, the power of an electronic radiation amplifier can be turned on and off and adjusted. The first mechanical operating device may be a rotary and/or key switch and is mounted on the housing of the night vision attachment, for example. The second mechanical operating means may similarly be in the form of a switch, such as a rotary and/or key switch. Because of the aforementioned long gun, the night vision attachment is usually arranged outside the range of easy operation for the marksman, and the second mechanical operation is arranged remote from the attachment housing in order to operate the switch on the attachment, which requires an undesired action. In particular, the second mechanical operating device is arranged at a distance from the housing of the night vision attachment which corresponds approximately to the longitudinal dimension of the sighting telescope, for example close to the trigger of the gun or close to or on the marksman. The second mechanical switching device according to the invention therefore allows direct activation by the marksman when necessary. The design of the second mechanical switching device may comprise, for example, a cable arranged on or around the sighting telescope and a control knob which is arranged in a position which is convenient for the marksman to operate. For example, the cable connects the control button to, for example, a first electronic switching device. The night vision attachment has a second electronic device, for example a microswitch, in which case the first electronic switching device can be activated by means of a first mechanical switching device and the second electronic switching device can be activated by means of a second mechanical switching device. Similarly, the night vision attachment may also have only one electronic switching device and two mechanical switching devices, which can be activated by means of the first mechanical switching device and/or the second mechanical switching device. Preferably, the second mechanical switching device is removable and replaceable, which facilitates both left-handed and right-handed marksman, so that good operation is possible both on the left and on the right.

Detailed Description

Fig. 1 schematically shows a diagram of the optical elements of a night vision attachment NSV and a sighting telescope ZF downstream thereof. The housing VG of the night vision attachment and the housing FG of the sighting telescope are indicated by dotted lines. Neither figure 1 nor the subsequent figures are to be considered to be drawn to scale. The sighting telescope ZF shown is therefore clearly too short, for example, in comparison with a night vision attachment. The dashed lines depict the optical axis a1 of the attachment objective 1 and the optical axis a2 of the attachment eyepiece 4, as well as the optical axis of the sighting telescope ZF. The optical axis a2 of the attachment eyepiece 4 and the optical axis of the sighting telescope ZF coincide with one another. The attachment NSV can be detachably connected to the sighting telescope ZF by means of a simple push-on. During daytime operation, (marksman) can observe with the sighting telescope ZF without the night vision attachment, while during night operation the target radiation scattered from the target or scene to be observed, which may originate from the moon, stars or artificial light sources such as town lights, street lights, and also from scattering of artificial light sources such as clouds, is collected by the objective 1 of the night vision attachment. Since the obtainable target radiation is weak, an objective lens which is as robust and as large as possible is required. The construction of the objective lens is usually a compromise between size, weight and compactness of the layout. A large attachment objective can create a relatively large and inconvenient burden to carry. Furthermore, a relatively large objective lens requires a long beam path or a large number of optical elements to focus the collected radiation, which elements may lead to a loss of radiation. In the night vision attachment NSV in the working example shown, the target radiation received through the attachment objective 1 converges along a first axis, i.e. the optical axis a1 of the attachment objective 1, onto the entrance window of the low-illumination amplifier 2 and is then displayed as an enlarged image on the exit window of the amplifier. The image further reaches the optical assembly 3 along the first axis, the optical assembly 3 firstly serving as an image reversal system and secondly as a deflection system for deflecting the image radiation onto the optical axis a2 of the night vision attachment eyepiece 4 and the sighting telescope ZF. The optical axis a2 is parallel to and offset by a height relative to the first axis. Since the target radiation is shifted inside the night vision attachment to the optical axis a2 of the sighting telescope ZF, the night vision attachment and the sighting telescope ZF can be mounted on the same horizontal plane. The radiation from the attachment eyepiece 4 is received into the sighting telescope objective 1a and then further passes through the sighting telescope elements 5, 5' to the sighting telescope eyepiece 4 a. The observer can observe the non-inverted upright image through the sighting telescope ZF (which serves as a receiver for the magnified image radiation of the night vision attachment ZSV) or the sighting telescope eyepiece 4 a.

Fig. 2 shows an example of operation of a night vision attachment according to the invention on the basis of optical elements shown in outline. As can be clearly seen from the figure: essentially along the optical axis a1 ' of the attachment objective 1 ', how the radiation passing through the low-intensity amplifier 2 ' to the prism system as an optical component, which prism system employs a porro prism system 3 ' of the second type, is guided through the prism system onto the optical axis a2 '. The second type of porro prism system 3' is arranged between the objective axis and the eyepiece axis. This porro prism system is a porro prism system of the second type for image reversal and for achieving a desired beam offset between the radiation entering through the night vision mirror objective 1 'and the radiation emerging via the night vision attachment eyepiece 4'. The arrows in fig. 2 show the direction of the beam path.

Fig. 3 shows a sighting telescope ZF 'with attached night vision attachment NSV'. The sighting telescope and the night vision attachment are mounted on the mounting rail S. The night vision attachment NSV has on its housing a knob D as a first mechanical switching device, by means of which a first electronic switching device in the attachment can be actuated in order to set the functions of the attachment, such as switching and calibration of the amplifier part. The figure also shows a first and a second adjuster 7, 7 'for adjusting the crosshairs of the sighting telescope ZF'. By rotating the first actuator 7 the position of the crosshair can be moved laterally, by rotating the second actuator 7' height adjustment of the crosshair position can be performed. According to an embodiment of the night vision attachment NSV 'of the invention, the sighting telescope ZF' and the night vision attachment can be mounted on the same supporting surface of the mounting rail S. The mounting system is thus more stable against applied forces than those systems which cannot be mounted substantially directly on the mounting rail S along its length.

Fig. 4 shows an embodiment of a night vision attachment NSV "with improved operability. Since, in the arrangement with the night vision attachment module connected in front of the sighting telescope ZF ″, as shown in particular in fig. 5, the control knob D 'as the first mechanical switching device of the night vision attachment module is outside the range that can be directly controlled by the marksman, the marksman has to take a large, significant action in order to activate said control knob, which would jeopardize the marksman's safety. According to the invention, the external operating device 11 as a second mechanical switching device for actuating the first electronic switching device is coordinated with the night vision attachment NSV ″, which can be positioned in a position easily accessible to the marksman. In the illustrated working example, the second mechanical switching device (operating device 11) is provided in addition to the operating switch D' as the first mechanical switching device. This redundancy in the device provides additional protection in view of damage to one of the two operating elements. The electronic switching device can be actuated by means of a control knob D' or an external operating device 11 (for example a knob or a push button) connected to the electronic switching device via a cable 12. In this case, the cable 12 is wound helically around the sighting telescope ZF ″.

Fig. 5 further shows the mounting advantages of the night sighting telescope NZF described above. The night sighting telescope NZF, which is mounted on rails and comprises the sighting telescope and the night vision attachment in fig. 3, is here mounted on a gun as sighting device. The firearm has a housing G with a snap-in magazine M, a shoulder rest 8 with a thumb hole 9 and a barrel R. The barrel R is inserted into the barrel casing H of the casing G and screwed into the casing. The night sighting telescope NZF is mounted on the barrel R, which mounting is shown only by way of example. It is however evident from the figure that the entire system is compact and convenient, since the sighting telescope and the night vision attachment are mounted very close to the housing G and substantially on the same supporting surface. The sniper hand is therefore easier to operate both the hand-held firearm and the sighting telescope, and this also provides a system which is stable against the impulsive forces exerted during shooting.

Fig. 6 shows another working example of a night sighting telescope NZF' mounted on a gun, in this case on an assault rifle SG. The assault rifle SG is supported by a bipod 10 so that a marksman who is lying down or lying over a cover can easily handle the gun. Similarly to the working example in fig. 4, the night sighting telescope NZF 'mounted on the gun by means of the mounting rail S' on the gun has an external mechanical switching device for operating the electronic switching device of the night vision attachment. There is a cable connection between the operating switch 11', which represents an external mechanical switching device, and the electronic switching device of the night vision attachment. As an alternative to the working example of fig. 4, the cable 12 'extends along the mounting rail S' and the firearm and is secured by a clip. In order to allow flexible positioning of the operating switch 11 ', the cable 12' is wound up several times. Of course, the cable may also be tensioned. The operating switch 11' is mounted in a position on the assault rifle SG that is easily accessible to the marksman. Advantageously, the external mechanical operating device is arranged at a distance from the attachment housing, i.e. at a distance from the end of said housing on the eyepiece side of the attachment which corresponds at least to the longitudinal dimension of the sighting telescope.

Fig. 7 shows an example of the operation of the external mechanical switching device. The external mechanical switching device ("remote control" device) takes the form of a rotary switch 11 a. By rotating the switch 11a, the intensity of the image amplified in the low-light amplifier of the night vision attachment can be adjusted and the low-light amplifier can be switched on and off. A fixing element 11 a' for fixing to the gun is used in cooperation with the rotary switch 11 a. The rotary switch 11a is constructed to be able to be fixed and to be conveniently operated in a full angular position of 0 to 360 degrees. The mounting position of the rotary switch 11a can thus be adapted to the various gun types, gun supports and marksman preferences. The operating switch 11a may also be arranged on the left or right side of the night sighting telescope or gun. This arrangement can be carried out on the firearm, for example close to the trigger or close to the marksman, or directly on the marksman, for example on the shoulder or on the belt of the marksman. In the drawing, an external mechanical switching device according to the invention is shown in connection with a night vision attachment according to the invention. However, the external mechanical switching device according to the invention is of course also suitable for other night vision attachments.

Fig. 8A and 8B show another working example of the external mechanical switching device according to the present invention. Fig. 8A shows a top view of a push-and-turn switch 11B as an operating device of an electronic switching device of a night vision attachment, and fig. 8B shows a partial top view and a side view of the push-and-turn switch 11B. By pressing the switch, the turn-on function can be initiated; pressing the switch again will start the shut down function. By rotating the switch, the amplification power of the radiation amplifier of the night vision attachment can be continuously adjusted. The switch can also be formed to be adjustable in stages. In this way, the degree of amplification of the radiation received by the night vision attachment can be adjusted for different visual conditions. The push-and-turn switch 11b can be connected to an electronic switching device in the night vision attachment by a cable 12 b. Communication via a wireless connection may also be implemented if desired. The rotary and push switch 11B of fig. 8A, 8B may further have a hollow housing formed to allow the carrying element (e.g. strap 13) to pass through, thus enabling a captive connection.

Fig. 9 shows, based on the marksman 14, a carrier for an operating device 11c, which operating device 11c is a mechanical switching device according to the invention for an electronic switching device of a night vision attachment. The marksman 14 carries a shoulder strap 13a, on which the operating device 11c is mounted, for example, which is pulled over the operating device 11c (as shown in the embodiment of fig. 8A and 8B), or the operating device 11c merely snaps onto the shoulder strap. The operating device 11c may also be mounted on the belt. The marksman 14 can also decide whether the operating device 11c is to be passed to the left or to the right, for example depending on whether he is a right-handed marksman or a left-handed marksman.
