U.S. Pat. No. 7,225,718 discloses a device for using reflectors to see out of a military vehicle window. The device uses an upper armored plate with reflective covering disposed on its underside. A lower reflector is placed below the upper plate and ahead of a lower armored plate. This configuration enables an occupant of the vehicle to see out windows of a military vehicle and remain protected from projectiles fired at the vehicle. While successful, the field of view as seen by the occupant of a vehicle is not adjustable because the reflectors are fixed in place. Also, light striking the lower reflector is redirected toward a vehicle occupant's eyes without being filtered.
The present invention is an improvement for a window cover used for viewing out of a window. The window cover has a first armored plate and a viewing reflector in front of the first armored plate. The viewing reflector is angled away from the window and reflects light directed toward the window. The viewing reflector is penetrable by a projectile fired at the vehicle toward the window. A second armored plate is in front of the window. The second armored plate has an inner surface and an outer surface. The inner surface faces the window at an angle relative to the window. A stationary reflector is secured to the inner surface of the second armored plate. The stationary reflector is opposite the viewing reflector so that at least a portion of the light striking the viewing reflector and reflected from it may be reflected off the stationary reflector through the window.
A filter for light is placed between the viewing and stationary reflectors. The filter filters out portions of light passing through it and may also include a collimator.
An object of the invention is to provide a window cover that has an adjustable field of view.
Another object of the invention is to provide a field of view similar to that of a traditional window.
Another object of the invention is to provide a filter for light that passes through a window cover for a vehicle.
Still other objects of the invention will become apparent upon reading the following description.
A window cover 10 shown in
An occupant 18 of the military vehicle 12 can change his field of view by pivoting the viewing reflector 24. This may be done with a crank 32 attached to a worm gear assembly 34 as shown in
In the configuration shown in
During use, an occupant 18 looks through window 14 as would be done in the absence of the window cover 10 of this invention. Light that enters the viewing window 20 is reflected from the viewing reflector 24 to the stationary reflector 26 and then on to the occupant's 18 eyes. When the occupant 18 wishes to change the view he can see, he may change the position of the viewing reflector 24 by using the crank 32. The third reflector 29, placed above the viewing window 20 in the configuration shown in
The detailed description related herein is meant only to exemplify the preferred embodiment of the invention to enable those skilled in the art to make and use it. The subject invention is not limited to the details given, but may be modified within the scope of the following claims.
