Abstract

A binocular system includes a first monocular, a second monocular, a mounting bracket, a base plate, coupled to the mounting bracket, a first arm coupled to the base plate via a first hinge and coupled to the first monocular via a first guide rail, and a second arm coupled to the base plate via a second hinge and coupled to the second monocular via a second guide rail. The monoculars are independently moveable using the guide rails and the hinges. Collimation of the monoculars is maintained independently of movement of the monoculars side to side and fore and aft on the guiderails.

Claims

1. A binocular system, comprising:

a first monocular;

a second monocular;

a first arm coupled to a base plate via a first hinge and coupled to the first monocular; and

a second arm coupled to the base plate via a second hinge and coupled to the second monocular, wherein each of the monoculars rotates about a corresponding one of the hinges to increase a transverse distance between the monoculars in an unused state and so that a normally forward portion of the monocular faces backward and wherein the monoculars are collimated to less than one degree of convergence and less than 0.3 degrees of dipvergence/divergence when deployed in a deployed position, and wherein, in the deployed position, the monoculars are movable without changing the collimation therebetween.

2. A binocular system, according to claim 1, further comprising:

a mounting bracket coupled to the base plate;

a tilt base, interposed between the mounting bracket and the base plate; and

a tilt lever, having a cam that is operatively engaged with the tilt base, wherein actuation of the lever causes the base plate to tilt with respect to the mounting bracket.

3. A binocular system, according to claim 2, wherein tilting the monoculars does not change collimation thereof when deployed.

4. A binocular system, according to claim 1, further comprising:

a mounting bracket coupled to the base plate;

a tilt base, interposed between the mounting bracket and the base plate, the tilt base having notches therein;

a height adjustment lever having a portion that engages the notches of the tilt base; and

a spring that urges the height adjustment lever toward the notches, wherein disengaging the height adjustment lever from the notches allows for the height of the monoculars to be adjusted.

5. A binocular system, according to claim 4, wherein adjusting the height of the monoculars does not change collimation thereof when deployed.

6. A binocular system, according to claim 1, wherein the arms are oriented at substantially a 50 degree angle with respect to a horizontal axis.

7. A binocular system, according to claim 6, wherein rotating each of the monoculars about a corresponding hinge thereof causes each of the monoculars to be in an unused state.

8. A binocular system, according to claim 7, wherein the monoculars may be independently placed in an unused state.

9. A binocular system, according to claim 7, wherein the system is mounted on a helmet.

10. A binocular system, according to claim 9, wherein each of the monoculars placed in an unused state is maintained below the top of the helmet.

11. A binocular system, according to claim 1, further comprising:

a mounting bracket coupled to the base plate;

a helmet mount insert slide slidably coupled to the mounting bracket and having a lip thereon; and

an opposing lip provided on the mounting bracket, wherein sliding the helmet mount insert slide changes the distance between the lips.

12. A binocular system, according to claim 11, further comprising:

a mounting plate attached to a helmet; and

a spring that urges the lips apart, wherein the binocular system is attached to a helmet by urging the lips closer together using the helmet mount insert slide and then inserting the mounting bracket in the mounting plate prior to releasing the helmet mount insert slide.

13. A binocular system, according to claim 1, wherein at least one of the monoculars is a night vision device.

14. A binocular system, according to claim 1, further comprising:

a battery compartment; and

a rotary switch.

15. A binocular system, according to claim 1, further comprising:

an external source, coupled to the binocular system, that provides an electronic signal thereto.

16. A binocular system, according to claim 15, wherein the electronic signal is a thermal image signal.

17. A binocular system, according to claim 16, wherein the thermal image signal is superimposed on a visual image provided by one of the monoculars.

18. A binocular system, according to claim 16, wherein the thermal image signal replaces a visual image provided by one of the monoculars.
