1. A viewing apparatus comprising:
- a frame for being supported relative to a user'"'"'s head and eyes;
said frame supporting a pair of night vision monocular scope mounts for lateral relative movement;
said pair of scope mounts carrying a respective left-eye and right-eye night vision monocular scope disposed in front of said user'"'"'s eyes for cooperatively providing binocular vision, and defining therebetween an interpupillary distance;
said frame carrying means for laterally moving and positioning said monocular scope mounts relative to said frame to adjust said interpupillary distance, said moving and positioning means including a pair of respective laterally-extending threaded shaft members journaled by said frame and each threadably associated with a respective one of said pair of scope mounts to move the latter laterally of said frame in response to rotation of said shaft member, and said pair of shaft members being substantially identical with one another.

Abstract
A binocular night vision device includes a pair of night vision monocular scopes which adjustably depend from a support frame in front of a user'"'"'s eyes. The support frame includes an interpupillary distance adjustment mechanism which allows non symmetrical placement of the monocular scopes to better achieve binocular vision with depth perception. Also, the adjustment mechanism allows adaptive duplicative use of identically the same component parts of the device on both the left and right sides of the support frame so that the number of different parts required for the device is reduced.

- 11. A binocular night vision device comprising a frame supported relative to a user'"'"'s head and eyes, a pair of night vision monocular scopes depending from said frame in front of the user'"'"'s eyes, and means for non symmetrical interpupillary distance adjustment of said pair of monocular scopes relative to said frame.
- 18. An ANVIS 6 type binocular night vision device with a pair of monocular night vision scopes cooperatively defining an interpupillary distance, and an interpupillary distance adjustment mechanism allowing independent lateral positional adjustment of the night vision monocular scopes of the device relative to a user'"'"'s head and eyes.

20. A retrofit kit for an ANVIS 6 type of binocular night vision device including a frame supporting a pair of monocular night vision scope mounts, and a monocular night vision scope disposed on each of said mounts to cooperatively provide binocular vision with depth perception, said retrofit kit providing for independent positioning of said scopes relative said frame to cooperatively define an interpupillary distance between eyepieces of said scopes, which interpupillary distance may be asymmetrically disposed relative said frame, said retrofit kit comprising:
-
a pair of substantially identical interpupillary distance control shaft assemblies each adapted to be journaled by said frame and to threadably associate with a respective one of said scope mounts, each control shaft having a thread portion of the same direction, and a replacement scope mount adapted to replace one of said pair of scope mounts of said ANVIS 6 night vision device, said replacement scope mount having a threaded bore of the same direction and threadably engageable with one of said pair of control shaft assemblies.

21. A viewing apparatus comprising:
-
a frame for being supported relative to a user'"'"'s head and eyes; said frame supporting a monocular viewing device for being disposed in front of a selected one of said user'"'"'s eyes, said frame further carrying means for laterally moving and positioning said viewing device to align the latter with said selected eye of the user, said moving and positioning means including a respective mount slidably carried on said frame for supporting said viewing device and a laterally-extending threaded shaft journaled by said frame, threadably engaging said mount to move the mount laterally in response to rotation of said threaded shaft and traversing only said selected eye of said user;
whereby lateral movement of said viewing device to align with said selected user eye is independent of lateral movement of another such viewing device mount which may be carried by said frame forwardly of the other of said user'"'"'s eyes. - View Dependent Claims (22, 23, 24, 25, 26, 27)
