Protection device for an optical apparatus of a vehicle, in particular of a military vehicle, having two protection elements (2, 3) which can be adjusted, by means of an adjustment device, in particular from a standby position beyond a viewing window for the optical device into a protection position in front of the viewing window of the optical device, wherein two protection levels can be set by means of the protection elements (2, 3).
Description
Protection device for an optical apparatus of a vehicle, in particular of a military vehicle The invention concerns a protection device for an optical apparatus of a vehicle, in particular of a military vehicle. Such optical apparatuses can be for example a periscope, a prism, a telescopic sight, or a night vision device. During normal operation of the vehicle there are usually no protective elements disposed in front of the optics in order to facilitate an unobstructed view. If the vehicle is however exposed to a threat, it is known to position a protective element in front of the viewing window of the optical apparatus for the purpose of the protection of the optics from a stand-by position into a protective position.
In order for the optical apparatus to be utilizable even with the protective element in the protective position, the protective element often features a small opening so that the field of view of the optical apparatus is diminished but reduced to zero. This is for example useful in the case of a periscope of a military vehicle during a combat mission, so that the commander can also continue to observe the surroundings.
By means of the protective element of the protection device a level of protection is provided for the optical apparatus. When the protective element is in the stand-by position, the field of view of the optical apparatus is not limited so that at the same time no protection is provided for the optical apparatus. If the protective element is positioned in front of the viewing window of the optical apparatus, a partial area of the viewing window is covered by the protective element.
The level of protection therefore goes along with the degree of cover that is achieved by means of the position of the protective element. In the case of a degree of cover of 50% the level of protection is also 50%. When the protective element is in the stand-by position and is therefore located away from the viewing window of the optical apparatus, there is also no protection provided for the optical apparatus so that in this case no level of protection is provided for the purpose of the invention.
In the case of other optical apparatuses, such as for example in the case of a coupled optical apparatus that encompasses an optical apparatus for a sun shield, for example a telescopic sight, as well as also an optical apparatus encompassing a night vision device, for example an infrared camera, it is possible in the case of a threat that an optical apparatus is completely covered by a protective element of a protective device because said protective device is not required in the case of a threat.
A coupled optical apparatus is for example described in DE 695 09 461 T2.
A protection device for an optical apparatus can be implemented in such a way that a flap-shaped protective element is pivoted in front of the viewing window of the optical apparatus that is not utilized, and covers the field of view completely. Consequently the protective element again provides only a level of protection for the optical apparatus.
A disadvantageous aspect of the known implementations is that in the protective position of the protective element the field of view of the optical apparatus is very severely limited. This is in particular of a disadvantage in the case when the observation of the threat is of particular interest. This can for example be the case if the vehicle is located, in the case of peace-keeping measures, in a crowd of people or observes a crowd of people during street fighting. The

Consequently the protective element again provides only a level of protection for the optical apparatus.
A disadvantageous aspect of the known implementations is that in the protective position of the protective element the field of view of the optical apparatus is very severely limited. This is in particular of a disadvantage in the case when the observation of the threat is of particular interest. This can for example be the case if the vehicle is located, in the case of peace-keeping measures, in a crowd of people or observes a crowd of people during street fighting. The
2 danger in this case is that out of crowd of people a person attempts to disable the optical apparatus of the vehicle, for example by throwing with stones, paint bags or such like at the optical apparatus. In the case where the protective element of the protection device is in the stand-by position, in which case it is located away from the viewing window of the optical apparatus, no protection whatsoever is provided for the optical apparatus. If the protective element is however located in the protective position, then the field of view is, because of the small opening of the protection device of the optical apparatus, limited to such an extent that a comprehensive observation of a larger angular range is not possible because of the high level of protection.
It is the object of the invention to provide the user of the optical apparatus, along with a sufficient level of protection, a larger field of view of the optical apparatus, wherein at the same time not forgoing a higher level of protection in the case of a threat.
The invention solves the problem with the characteristics of the patent claim 1. Advantageous improvements are part of the dependent claims.
A central idea of the invention is to provide, besides the first protective element that can be positioned in particular from a stand-by position located away from the viewing window of the optical apparatus into a protective position in front of the viewing window of the optical apparatus, a second protective element that likewise can be positioned in particular from a stand-by position into a protective position, wherein by means of the protective elements at least two levels of protection can be adjusted.
Preferably the second protective element can be positioned in the protective position in addition to the first protective element. It is according to the invention also possible that the second protective element can be positioned in the protective position instead of the first protective element. In an advantageous embodiment the second protective element can however be positioned in the protective position instead of the first protective element as well as also additionally to the first protective element, so that a third level of protection for the optical apparatus is provided.
The first level of protection in this case is achieved due to the fact that only the first protective element is in the protective position.
The second level of protection is achieved due to the fact that only the second protective element is in the protective position. The third level of protection is achieved due to the fact that both protective elements are in the protective position.
The protection device can be implemented such that in the case of a higher level of protection the field of view of the optical apparatus is diminished. In addition the field of view can be completely covered in the case of the highest level of protection by the first protective element and/or by the second protective element. This corresponds to a completely closed position of the protection device.

The first level of protection in this case is achieved due to the fact that only the first protective element is in the protective position.
The second level of protection is achieved due to the fact that only the second protective element is in the protective position. The third level of protection is achieved due to the fact that both protective elements are in the protective position.
The protection device can be implemented such that in the case of a higher level of protection the field of view of the optical apparatus is diminished. In addition the field of view can be completely covered in the case of the highest level of protection by the first protective element and/or by the second protective element. This corresponds to a completely closed position of the protection device.
3 The positioning of the protective elements takes place by means of an adjustment apparatus that can in particular encompass an electromotive drive. In a possible implementation the protective elements can be positioned independently of one another in the protective position. Preferably the protection device features only one adjustment apparatus for both protective elements. This can be accomplished due to the fact that the protective elements are coupled with one another.
In the protective position the protective elements can overlay one another at least partially. In order for the field of view of the optical apparatus to not be reduced completely to zero, the first and/or the second protective element can encompass at least one opening with a prescribed aperture area. By means of the openings the field of view of the optical apparatus can be established.
In a particularly preferred implementation the aperture areas of the first and second protective element are different.
By these means two levels of protection can be provided for the optical apparatus in a simple manner. If the protective elements overlay one another at least partially in the protective position, provision can in addition be made that an opening of the first protective element, in the protective position, is located above or below an opening of the second protective element.
As a result the user of the optical apparatus can see through the overlaying openings.
Preferably the protection device is designed in such a manner that the second protective element in the protective position covers at least one opening of the first protective element in the protective position. As the result the field of view can be varied by means of the protective elements, whereby at the same time the level of protection is modified.
Preferably the first and/or the second protective element are implemented flap-shaped. The openings of the first and/or second protective element can be implemented grid-shaped with an arbitrary grid structure. Preferably the openings are implemented slit-shaped.
In a particularly preferred implementation the protective elements are constructed complementary to one another in regard to their openings.
By means of the complementary implementation it is achieved that in an area where the first protective element features openings, the other element does not feature openings, and the reverse. By these means it is in particular possible that the second protective element engages, in the protective position, the first protective element in the protective position in a comb-like manner.
As a result the protection device can feature a closed surface to the outside so that the protection device is advantageously implemented in the protective position of the two protective elements from a ballistic point of view.
The protection device can according to the invention also be implemented for the protection of two neighboring optical apparatuses, wherein in this case at least one protective element is

The protection device can according to the invention also be implemented for the protection of two neighboring optical apparatuses, wherein in this case at least one protective element is
4 positioned in the protective position in front of the viewing windows of the two optical apparatuses.
In the case of an implementation of the protection device one, preferably all, protective elements can be disposed on a support device in a pivotable manner. The support device is preferably disposed on the optical apparatus in a torsionally rigid manner. By these means it can be achieved that the support device rotates with the protective elements during the rotation of the optical apparatus, for example a telescope, so that in every rotational position the protection continues to be provided for the optical apparatus.
In addition the second protective element can be displaceable and/or can be disposed on the first protective element such that it can swivel. Consequently the adjustment apparatus can be implemented in a simple manner. In addition the protection device can thereby be more compact from a construction point of view.
The protection device can be implemented such that at least one, in particular all, protective elements are movable from a position in which they are disposed perpendicularly to the viewing window of the optical apparatus into a position in which they are disposed parallel to the viewing window of the optical apparatus.
Preferably the protection device is additionally implemented in such a manner that the level of protection is continuously adjustable.
The optical apparatus can encompass a periscope, a prism, a telescopic sight and/or a night vision device.
Possible embodiment examples of the invention are described in regard to the figures 1 to 21.

Figures 1 to 7 present a protection device I for a commander's periscope P
that is disposed on the roof D of a military vehicle that is not further represented. The protection device I
encompasses two protective element 2 and 3 that are disposed on a support device 5. The support device 5 is disposed on the periscope P in a torsionally rigid manner.
The protection device 1 encompasses an adjustment apparatus 4 by means of which the two protective elements 2 and 3 can be pivoted from a stand-by position into the protective position that is represented in figure 1 and 2.
In the case of the position represented in the figures 3 to 5 the second protective element 3 is located in the stand-by position and the first protective element 2 is in the protective position in front of the viewing window of the periscope. The first protective element 2 features several, evenly distributed, slit-shaped openings 6.
By means of the first protective element 2, which according to figure 3 is positioned in the protective position, a first level of protection is provided for the optical apparatus. In the case of this first level of protection the field of view provided for the user of the optical apparatus is sufficiently large in order to be able to observe the surroundings well. At the same time sufficient protection is also provided against more minor threats such as stones or similar. In case of a larger threat the second protective element 3 can be pivoted in front of the viewing window of the optical apparatus in addition to the first protective element 2.
In this position, which is represented in figure 1, the protection for the optical apparatus is significantly increased, wherein the protection device thereby provides a second level of protection for the optical apparatus.
The second level of protection therefore also provides protection for example against projectiles.
The second protective element 3 features only a slit-shaped opening 7. It is positioned above an opening 6 of the protective element 2 so that the user of the optical apparatus can see through both openings that overlap one another. Due to the increased level of protection the field of view of the optical apparatus is however significantly diminished.
Figures 6 and 7 present the protection device with the two protection elements 2 and 3 in the stand-by position. The view through the periscope P is thereby not obstructed.
The adjustment apparatus 4 and the adjustment process are described based on figure 5: The two protective elements 2 and 3 are connected on both sides of the support device 5 by means of respectively one slide 14 with the support device 5, wherein the slide 14 is supported in a guide 15 in a displaceable manner. The slide 14 is moved by means of a spindle, which is respectively supported in a rotatable manner within the support device 5, and by means of drive belts that are driven via an electric motor. The protective element 3 is connected with the slide 14, via an oblong hole 11 and a pin 12 that is guided through the oblong hole 11, in such a manner that a swivel movement of the protective element 3 is possible. The protective element 2 is disposed on the slide 14 via a support pin 13 in a manner such that is can pivot so that the protective element 2 can be pivoted into the stand-by position.
When both protective elements 2 and 3 are located in the stand-by position (figure 6), the slide 14 is moved in the guide 15 until the stop pins 8, which are disposed on the protective element 2, engage the corresponding recesses 9 on the support device 5 so that the adjustment movement is limited and a positional lock is reached.
Figures 8 to 19 present three implementations of protection devices for a coupled optical apparatus that encompasses an infrared camera as a night vision device and a telescopic sight as a sun shield.
Figures 8 to 11 present a protection device 21 with two protective element 22 and 23 that are disposed on a support device 25. The second protective element 23 is implemented in a flap-shaped manner and features no opening. It covers, in the protective position presented in figure 9, the telescopic sight completely. The first level of protection is therefore provided for the sun shield by means of the second protective element 23 in the protective position.
The first protective element 22 is likewise implemented in a partial area in a flap-shaped manner so that it covers the night vision device completely in the protective position that is represented in figure 10. In addition the first protective element 22 features a grid-shaped section which, in the protective position (figure 10), is positioned in front of the viewing window of the sun shield. Thereby a second level of protection is provided for the sun shield by means of the protective element 22.
In figure 11 it is presented that both protective elements can also be simultaneously positioned in front of the optical apparatus so that the night vision device as well as also the sun shield is completely closed.
In figures 12 to 16 a further implementation of a protection device 41 is represented that can be utilized in the same manner as the protection device 21 that is represented in figures 8 to 11.
The protection device 41 that is disposed on the support device 45 in turn features two protective elements 42 and 43. In contrast to the previous implementation the second protective element 43 is implemented in regard to the openings in a complementary manner to the first protective element 42. Consequently a first level of protection according to the position represented in figure 13 can be achieved for the sun shield. A second level of protection is provided by means of the second protective element 43 that is represented in figure 14. A third level of protection finally is provided for the sun shield according to the position of the two protective elements 42 and 43 represented according to figure 15.
An additional implementation of a protection device 61 is represented in figures 16 to 19 that can be utilized for the same application purpose as the previous protection devices 21 and 41.
The protection device 61 encompasses again two protective element 62 and 63 that are disposed on a support device 65 in a manner that they can be pivoted. The two protection devices 62 and 63 are in regard to their openings constructed in a complementary manner and can be adjusted independently of one another. Consequently there are three levels of protection, which are respectively represented in the figures 14, 15, and 16, for the night vision device as well as also for the sun shield.
Figures 20 to 21 present a fifth implementation according to the invention of a protection device 81 that is disposed via a support device 85 on the prism Won top of the roof D of a military vehicle that is not further represented.
The protection device 85 features two outer protective elements 82 and a center protective element 83 that are coupled mechanically by means of struts 89 and can be pivoted, by means of a lever 88 that is manually activated, into the protective position represented in figure 21.
The protective elements 82 and 83 feature recesses 86 that represent in the protective position (figure 21) circular openings that permit a minimal view through the prism in the case of a high level of protection. In the case of opened protective elements 82 and 83 according to figure 20 a better view is provided, wherein by means of the center protective element 82, which as before is positioned in front of the viewing window of the prism W, a basic protection is provided at a lowered level of protection. Consequently the protective elements 32 and 33 in figure 20 are in a partial protective position.
By means of the adjustment apparatus 85, which encompasses the struts 89, the protective elements 82 and 83 can be pivoted out of the protective position according to figure 21, in which they are disposed parallel to the viewing window S of the optical apparatus, into the partial protective position according to figure 20 in which they are disposed perpendicularly to the viewing window S of the optical apparatus. Intermediate positions are therefore also possible in which the protective elements 82 and 83 are disposed obliquely to the viewing window S. Consequently in the case of this advantageous embodiment a continuous adjustment of the level of protection is possible.
In the case of an implementation of the protection device one, preferably all, protective elements can be disposed on a support device in a pivotable manner. The support device is preferably disposed on the optical apparatus in a torsionally rigid manner. By these means it can be achieved that the support device rotates with the protective elements during the rotation of the optical apparatus, for example a telescope, so that in every rotational position the protection continues to be provided for the optical apparatus.
In addition the second protective element can be displaceable and/or can be disposed on the first protective element such that it can swivel. Consequently the adjustment apparatus can be implemented in a simple manner. In addition the protection device can thereby be more compact from a construction point of view.
The protection device can be implemented such that at least one, in particular all, protective elements are movable from a position in which they are disposed perpendicularly to the viewing window of the optical apparatus into a position in which they are disposed parallel to the viewing window of the optical apparatus.
Preferably the protection device is additionally implemented in such a manner that the level of protection is continuously adjustable.
The optical apparatus can encompass a periscope, a prism, a telescopic sight and/or a night vision device.
Possible embodiment examples of the invention are described in regard to the figures 1 to 21.

Figures 1 to 7 present a protection device I for a commander's periscope P
that is disposed on the roof D of a military vehicle that is not further represented. The protection device I
encompasses two protective element 2 and 3 that are disposed on a support device 5. The support device 5 is disposed on the periscope P in a torsionally rigid manner.
The protection device 1 encompasses an adjustment apparatus 4 by means of which the two protective elements 2 and 3 can be pivoted from a stand-by position into the protective position that is represented in figure 1 and 2.
In the case of the position represented in the figures 3 to 5 the second protective element 3 is located in the stand-by position and the first protective element 2 is in the protective position in front of the viewing window of the periscope. The first protective element 2 features several, evenly distributed, slit-shaped openings 6.
By means of the first protective element 2, which according to figure 3 is positioned in the protective position, a first level of protection is provided for the optical apparatus. In the case of this first level of protection the field of view provided for the user of the optical apparatus is sufficiently large in order to be able to observe the surroundings well. At the same time sufficient protection is also provided against more minor threats such as stones or similar. In case of a larger threat the second protective element 3 can be pivoted in front of the viewing window of the optical apparatus in addition to the first protective element 2.
In this position, which is represented in figure 1, the protection for the optical apparatus is significantly increased, wherein the protection device thereby provides a second level of protection for the optical apparatus.
The second level of protection therefore also provides protection for example against projectiles.
The second protective element 3 features only a slit-shaped opening 7. It is positioned above an opening 6 of the protective element 2 so that the user of the optical apparatus can see through both openings that overlap one another. Due to the increased level of protection the field of view of the optical apparatus is however significantly diminished.
Figures 6 and 7 present the protection device with the two protection elements 2 and 3 in the stand-by position. The view through the periscope P is thereby not obstructed.
The adjustment apparatus 4 and the adjustment process are described based on figure 5: The two protective elements 2 and 3 are connected on both sides of the support device 5 by means of respectively one slide 14 with the support device 5, wherein the slide 14 is supported in a guide 15 in a displaceable manner. The slide 14 is moved by means of a spindle, which is respectively supported in a rotatable manner within the support device 5, and by means of drive belts that are driven via an electric motor. The protective element 3 is connected with the slide 14, via an oblong hole 11 and a pin 12 that is guided through the oblong hole 11, in such a manner that a swivel movement of the protective element 3 is possible. The protective element 2 is disposed on the slide 14 via a support pin 13 in a manner such that is can pivot so that the protective element 2 can be pivoted into the stand-by position.
When both protective elements 2 and 3 are located in the stand-by position (figure 6), the slide 14 is moved in the guide 15 until the stop pins 8, which are disposed on the protective element 2, engage the corresponding recesses 9 on the support device 5 so that the adjustment movement is limited and a positional lock is reached.
Figures 8 to 19 present three implementations of protection devices for a coupled optical apparatus that encompasses an infrared camera as a night vision device and a telescopic sight as a sun shield.
Figures 8 to 11 present a protection device 21 with two protective element 22 and 23 that are disposed on a support device 25. The second protective element 23 is implemented in a flap-shaped manner and features no opening. It covers, in the protective position presented in figure 9, the telescopic sight completely. The first level of protection is therefore provided for the sun shield by means of the second protective element 23 in the protective position.
The first protective element 22 is likewise implemented in a partial area in a flap-shaped manner so that it covers the night vision device completely in the protective position that is represented in figure 10. In addition the first protective element 22 features a grid-shaped section which, in the protective position (figure 10), is positioned in front of the viewing window of the sun shield. Thereby a second level of protection is provided for the sun shield by means of the protective element 22.
In figure 11 it is presented that both protective elements can also be simultaneously positioned in front of the optical apparatus so that the night vision device as well as also the sun shield is completely closed.
In figures 12 to 16 a further implementation of a protection device 41 is represented that can be utilized in the same manner as the protection device 21 that is represented in figures 8 to 11.
The protection device 41 that is disposed on the support device 45 in turn features two protective elements 42 and 43. In contrast to the previous implementation the second protective element 43 is implemented in regard to the openings in a complementary manner to the first protective element 42. Consequently a first level of protection according to the position represented in figure 13 can be achieved for the sun shield. A second level of protection is provided by means of the second protective element 43 that is represented in figure 14. A third level of protection finally is provided for the sun shield according to the position of the two protective elements 42 and 43 represented according to figure 15.
An additional implementation of a protection device 61 is represented in figures 16 to 19 that can be utilized for the same application purpose as the previous protection devices 21 and 41.
The protection device 61 encompasses again two protective element 62 and 63 that are disposed on a support device 65 in a manner that they can be pivoted. The two protection devices 62 and 63 are in regard to their openings constructed in a complementary manner and can be adjusted independently of one another. Consequently there are three levels of protection, which are respectively represented in the figures 14, 15, and 16, for the night vision device as well as also for the sun shield.
Figures 20 to 21 present a fifth implementation according to the invention of a protection device 81 that is disposed via a support device 85 on the prism Won top of the roof D of a military vehicle that is not further represented.
The protection device 85 features two outer protective elements 82 and a center protective element 83 that are coupled mechanically by means of struts 89 and can be pivoted, by means of a lever 88 that is manually activated, into the protective position represented in figure 21.
The protective elements 82 and 83 feature recesses 86 that represent in the protective position (figure 21) circular openings that permit a minimal view through the prism in the case of a high level of protection. In the case of opened protective elements 82 and 83 according to figure 20 a better view is provided, wherein by means of the center protective element 82, which as before is positioned in front of the viewing window of the prism W, a basic protection is provided at a lowered level of protection. Consequently the protective elements 32 and 33 in figure 20 are in a partial protective position.
By means of the adjustment apparatus 85, which encompasses the struts 89, the protective elements 82 and 83 can be pivoted out of the protective position according to figure 21, in which they are disposed parallel to the viewing window S of the optical apparatus, into the partial protective position according to figure 20 in which they are disposed perpendicularly to the viewing window S of the optical apparatus. Intermediate positions are therefore also possible in which the protective elements 82 and 83 are disposed obliquely to the viewing window S. Consequently in the case of this advantageous embodiment a continuous adjustment of the level of protection is possible.
