ABSTRACT:
A binocular display device can include first and second display assemblies. A rail system can adjustably support the first and second display assemblies. The rail system can have a first rail slidably secured to a front region of the display assemblies, and second rail slidably secured to a rear region of the display assemblies. One rail can be at an upper region and the other rail can be at a lower region. Each display assembly can be slidably mounted to one rail along a bearing length L1and to the other rail along a bearing length L2that is less than the bearing length L1. A release/locking system can be included for releasing the display assemblies relative to the rail system to allow the position of the display assemblies relative to each other on the rail system to be adjusted, and for locking the display assemblies at a desired position.
