Abstract

A mounting assembly for mounting two monocular devices to form a binocular device. A method of collimating the monocular devices, so that the binocular device is collimated.

Claims

1. A mounting assembly for mounting two monocular type night vision devices to form a binocular type night vision device, comprising:

a pair of arms, a mounting block secured to each arm for interfacing with a respective monocular type night vision device, a screw having first and second ends for each monocular device, the first end passing through a mounting block and being threaded for insertion in a monocular device and the second end bearing a control knob, the mounting blocks being mounted on rails projecting from the arms for sliding movement, each mounting block having a first surface for engaging a monocular device and the respective arms being bent such that the first surfaces of the respective blocks face each other and the mounting blocks are located about the same distance in two perpendicular directions from a central point between the arms.

2. Apparatus for mounting two monocular devices to form a binocular device, comprising;

a pair of arms having outer ends, a mounting region located near each outer end, said mounting regions defining a distance therebetween which corresponds to a desired, nominal binocular spacing between two monocular devices; and

a pair of fasteners, each of which is for removably securing a respective monocular device to a said mounting region, each fastener being situated at a mounting region and being arranged so that the respective monocular devices are moveable in a straight line in a direction which varies the actual spacing between the monocular devices, wherein each fastener comprises;

a mounting block slidably secured to a respective mounting region for interfacing with a monocular device; and

an attachment device for attaching the mounting block to the monocular device and for attaching the mounting block to the arm, the attachment device being a screw having first and second ends, wherein the first end passes through an opening in the mounting region as well as through an opening in the mounting block for insertion into a threaded opening in the monocular device.

3. The apparatus of claim 2 wherein the screw has a control knob at the second end, so that the screw may be loosened to effect movement of the mounting blocks.

4. The apparatus of claim 3 wherein the mounting regions have rails on which the mounting blocks slide.

5. The apparatus of claim 4 wherein each mounting block has at least one alignment protrusion protruding therefrom for insertion into a corresponding recess on a monocular device for aligning the monocular device and for preventing rotation thereof.

6. The apparatus of claim 5 wherein each mounting block has a first surface for engaging a monocular device, wherein the respective arms are bent such that the first surfaces of the respective mounting blocks face each other.

7. The apparatus of claim 6 wherein the respective arms are L-shaped and include first and second portions which are perpendicular to each other, wherein the first portions of the respective arms extend towards a central plane and wherein the second portions are of similar dimension such that the mounting regions of the respective arms are about the same distance from the central plane.

8. Apparatus for mounting two monocular devices to form a binocular device, comprising;

a pair of arms having outer ends, a mounting region located near each outer end, said mounting regions defining a distance therebetween which corresponds to a desired, nominal binocular spacing between two monocular devices; and

a pair of fasteners, each of which is for removably securing a respective monocular device to a said mounting region, each fastener being situated at a mounting region and being arranged so that the respective monocular devices are movable in a straight line in a direction which varies the actual spacing between the monocular devices, wherein each fastener comprises;

a mounting block slidably secured to a respective mounting region for interfacing with a monocular device; and

an attachment device for attaching the mounting block to the monocular device, wherein each mounting block has a first surface for engaging a monocular device and wherein the respective arms are bent such that the first surfaces of the respective mounting blocks face each other.

9. The apparatus of claim 8 wherein the respective arms are L-shaped and include first and second portions which are perpendicular to each other, wherein the first portions of the of the respective arms extend towards a central plane and wherein the second portions are of similar dimension such that the mounting regions of the respective arms are about the same distance from the central plane.

10. The apparatus of claim 9 further including a central assembly between the arms for attaching the apparatus to a helmet or head mounting gear.

11. The apparatus of claim 8 in combination with a pair of respective monocular devices which are fastened to respective mounting blocks.

12. An apparatus for mounting two monocular type night vision devices to form a binocular type night vision device comprising two arms extending in generally opposite directions with respect to a central point, each arm bearing a mounting surface near a respective end for interfacing with a predetermined region of a monocular type night vision device when such devices are mounted in the apparatus, wherein the arms are bent such that said respective mounting surfaces are separated from each other both laterally and in elevation with respect to said central point, face in opposite directions, and are oriented in generally horizontal, parallel planes when said monocular night vision devices are mounted and the binocular device is positioned for horizontal viewing.

13. The apparatus of claim 12 further including a mounting region near the end of each arm, respective mounting blocks being located at respective mounting regions, said respective mounting surfaces being part of said respective mounting blocks, said mounting regions having rails and said mounting blocks being slidably secured to said rails for movement in the lateral direction for varying the distance between the monocular devices.
