Abstract

An improved monocular/binocular bridge and helmet mounting device employing same for an optical device are provided. The mounting device herein includes a mount with a bridge attachment for providing multiple options for a monocular or binocular optical device and multiple options for moving the attached optical device to any of multiple stowed positions out of the user'"'"'s line of sight when the optical device is not in use. The bridge attachment and multiple stow positions also allow the unit to be adapted for a variety of viewing devices.

Claims

1. A bridge mount assembly for mounting an optical device to a helmet, the assembly comprising:

a mounting shoe member, and

a bridge mounting member;

wherein the mounting shoe member comprises a mounting shoe that mates with a mounting shoe receiver attached to the helmet, the bridge mounting member attaches the optical device to the bridge mount assembly, and the bridge mounting member comprises a pivot arm that allows rotation of the optical device around a pivot axis.

2. The bridge mount assembly of claim 1, comprising first and second bridge mounting members for attachment of first and second optical devices.

3. The bridge mount assembly of claim 1, wherein the mounting shoe member is disposed in a central portion of the assembly and is adapted to mate with a bridge mounting member at the left and/or right side of the mounting shoe member.

4. The bridge mount assembly of claim 3, wherein the mounting shoe member comprises left and/or right channels that mate with a corresponding protrusion on a bridge mounting member.

5. The bridge mount assembly of claim 4, wherein the channel and protrusion are angled and the bridge mounting member is secured with a threaded knob to prevent wobbling when in use.

6. The bridge mount assembly of claim 1, wherein the mounting shoe is complementary in shape to a receptacle in the mounting shoe receiver.

7. The bridge mount assembly of claim 1, wherein the bridge mounting member comprises a mounting shoe that slides into a complementary shaped mounting shoe receiver on the optical device.

8. The bridge mount assembly of claim 7, wherein the mounting shoe of the bridge mounting member comprises a pressure foot that is pushed into a base surface in the mounting shoe upon application of pressure to the pressure foot.

9. The bridge assembly of claim 8, wherein pressure is applied to the pressure foot via a camshaft attached to a rotating knob.

10. The bridge assembly of claim 7, wherein the pivot arm is attached to a first pivot sleeve and the mounting shoe is attached to a second pivot sleeve;

wherein the first and second pivot sleeves rotate around a central rod that is coaxial with the pivot axis; and

wherein the rotation of the first pivot sleeve provides a tilt angle adjustment of the optical device for pupillary and/or interpupillary distance and rotation of the second pivot sleeve provides rotation of the optical device around the pivot axis.

11. The bridge assembly of claim 10, wherein the central rod is attached to an arm that rotates the first pivot sleeve around the central rod.

12. The bridge assembly of claim 11, wherein the arm comprises a magnet that switches off the optical device when the optical device is in a stowed position.

13. The bridge assembly of claim 7, further comprising a rotational set stop with a first opening and an oblong opening, wherein the central rod passes through the first opening and a threaded fastener passes through the oblong opening to a threaded hole in the first pivot arm, and wherein the threaded fastener can be used to lock the position of the first pivot arm and to set the pupillary and/or interpupillary distance.

14. The bridge assembly of claim 1 which is adapted for mounting one or more optical devices selected from the group consisting of monoculars, binoculars, sighting devices, targeting devices, night vision devices, enhanced night vision goggles, thermal imaging devices, infrared imaging devices, short-wave infrared imaging devices, and helmet mounted display screens.

15. An optical bridge-helmet mount assembly comprising:

a bridge mount assembly for mounting an optical device to a helmet, the assembly comprising a mounting shoe member and a bridge mounting member, wherein the mounting shoe member comprises a mounting shoe that mates with a mounting shoe receiver attached to the helmet, the bridge mounting member attaches the optical device to the bridge mount assembly, and the bridge mounting member comprises a pivot arm that allows rotation of the optical device around a pivot axis; and

a helmet mount assembly that connects the bridge mount assembly to a helmet.

16. The optical bridge-helmet mount assembly of claim 15, wherein the helmet mount assembly comprises a pivot pin assembly that allows the bridge mount assembly to be pivoted between a lower position and an upper position for use and stowage, respectively, of an optical device attached to the bridge mount assembly.

17. The optical bridge-helmet mount assembly of claim 15, wherein the helmet mount assembly comprises a vertical adjustment mechanism.

18. The optical bridge-helmet mount assembly of claim 15, wherein the helmet mount assembly comprises a tilt adjustment mechanism.

19. A system comprising:

a bridge mount assembly for mounting an optical device to a helmet, the assembly comprising a mounting shoe member and a bridge mounting member, wherein the mounting shoe member comprises a mounting shoe that mates with a mounting shoe receiver attached to the helmet, the bridge mounting member attaches the optical device to the bridge mount assembly, and the bridge mounting member comprises a pivot arm that allows rotation of the optical device around a pivot axis;

a helmet mount assembly that connects the bridge mount assembly to a helmet; and

an optical device.

20. The system of claim 19, wherein the optical device is selected from the group consisting of monoculars, binoculars, sighting devices, targeting devices, night vision devices, enhanced night vision goggles, thermal imaging devices, infrared imaging devices, short-wave infrared imaging devices, and helmet mounted display screens.
