Abstract

A modular mounting system for a night vision device includes one or more night vision monoculars, each night vision monocular having an imaging tube, a housing, and a first mounting shoe at a first position on the housing. A power supply has a first fastener thereon. A helmet mount at a first location on a helmet has a second fastener thereon. A power supply interface is located at a second location on the helmet and a second mounting shoe is provided on the power supply interface. The first mounting shoe is interchangeably and removably attachable to the first fastener and the second fastener, and, the first fastener interchangeably and removably attachable to the first mounting shoe and the second mounting shoe. In a further aspect, a firearm rail interface is provided to allow the night vision monocular to alternatively be positioned on a firearm accessory rail.

Claims

1. A modular mounting system for a night vision device, comprising:

at least one night vision monocular, each night vision monocular having an imaging tube received within a night vision monocular housing and a plurality of mounting shoes attached directly to the night vision monocular housing and angularly spaced about the night vision monocular housing;

a power supply accessory device;

a helmet mount configured to be attached to a first location on a helmet;

the plurality of mounting shoes including;

first and second mounting shoes, the first and second mounting shoes being alike and each configured to be removably attached to a complimentary first helmet mount receptacle on the helmet mount; and

a third mounting shoe disposed between the first and second mounting shoes, the third mounting shoe configured to be removably attached to a complimentary power supply receptacle on the power supply accessory device, the third mounting shoe configured for removable electrical and mechanical coupling of the power supply accessory device and the at least one night vision monocular;

a power supply interface at a second location on the helmet, the power supply interface configured to alternately removably receive the third mounting shoe for electrically coupling the power supply accessory device and the at least one night vision monocular.

2. The modular mounting system of claim 1, wherein the power supply interface includes a first set of electrical contacts configured to contact a second set of electrical contacts on the third mounting shoe when the third mounting shoe is attached to the power supply interface.

3. The modular mounting system of claim 1, wherein the third mounting shoe is further configured to be removably attached to the first helmet mount receptacle on the helmet mount, the third mounting shoe configured for removable electrical and mechanical coupling of the helmet mount and the at least one night vision monocular.

4. The modular mounting system of claim 3, wherein the first helmet mount receptacle includes a first set of electrical contacts configured to contact a second set of electrical contacts on the third mounting shoe when the third mounting shoe is attached to the first helmet mount receptacle.

5. The modular mounting system of claim 1, further comprising a firearm mounting system, the firearm mounting system including:

a rail clamp for removably attaching the firearm mounting system to a rail interface of a firearm; and

a firearm mount interface attached to the rail clamp, the firearm mount interface removably attachable to a selected one of the first and second mounting shoes.

6. The modular mounting system of claim 5, further comprising a hinge pivotally attaching the firearm mount interface to the rail clamp, the hinge pivotal about an axis parallel to an axis of the firearm.

7. The modular mounting system of claim 1, further comprising a second helmet mount receptacle on the helmet mount adjacent the first helmet mount receptacle, the first and second mounting shoes being interchangeably and removably attachable to the first and second helmet mount receptacles.

8. The modular mounting system of claim 7, further comprising:

a first one of the at least one night vision monocular having the first mounting shoe removably attached to the first helmet mount receptacle; and

a second one of the at least one night vision monocular having the second mounting shoe removably attached to the second helmet mount receptacle.

9. The modular mounting system of claim 1, wherein the first helmet mount receptacle is adapted for interchangeably mounting one or more viewing devices selected from the group consisting of an optical device, opto-electronic device, sighting device, targeting device, night vision goggle device, enhanced night vision goggle device, thermal imaging device, infrared imaging device, short-wave infrared imaging device, and helmet-mounted display screen.

10. The modular mounting system of claim 1, wherein the helmet mount comprises a pivot assembly that allows the helmet mount to be pivoted between a lower, operational position and an upper, stowed position.

11. The modular mounting system of claim 1, wherein the helmet mount comprises a vertical adjustment mechanism.

12. The modular mounting system of claim 1, wherein the helmet mount comprises one or both of a tilt adjustment mechanism and a fore-and-aft adjustment mechanism.

13. The modular mounting system of claim 1, further comprising a breakaway connector which causes the helmet mount to detach from the helmet upon application of a predetermined force.

14. The modular mounting system of claim 1, wherein the power supply accessory device includes one or more batteries.

15. The modular mounting system of claim 14, wherein the power supply accessory device further includes an integral accessory device selected from the group consisting of an IR illuminator and a friend-or-foe identification device.

16. The modular mounting system of claim 1, further comprising:

the helmet mount including a center bridge member attached to a sliding carriage, the sliding carriage slidable in a fore-and-aft direction;

a side mounting member removably attachable to the center bridge member;

a hinge defining a pivot axis attaching the first helmet mount receptacle to the side mounting member, the hinge configured to allow pivoting movement of an attached one of the at least one night vision monocular about the pivot axis.

17. The modular mounting system of claim 16, wherein the pivot axis is parallel to a viewing axis of the attached night vision monocular.

18. The modular mounting system of claim 16, further comprising an IR illuminator on the center bridge member.

19. The modular mounting system of claim 16, further comprising:

a light sensor on the center bridge member operably coupled to the first helmet mount receptacle to provide a signal representative of an intensity of light impinging on the light sensor; and

circuitry for transmitting the signal to an auto gain circuit of the night vision monocular when the third mounting shoe is attached to the first helmet mount receptacle.

20. The modular mounting system of claim 1, wherein the first and second mounting shoes are angularly spaced by 180 degrees and the first and third mounting shoes are angularly spaced by 90 degrees.
