Abstract

The present invention is a mounting assembly for mounting a night vision apparatus onto a standard army issue helmet. The present invention includes a support member for retaining the night vision apparatus and a clamping assembly used to join the support member to the helmet. The clamping assembly is removably attachable to a standard army issue helmet above the eyes of the wearer. The support member is pivotably connected to the clamping assembly in a manner that enables the support member to be pivotably rotated about the clamping assembly between an operational position and a stowed position. At the operational position, the support member retains the night vision apparatus in front of the eyes of the wearer. At the stowed position, the night vision apparatus is "flipped up" to a position above the field of view of the wearer, where the night vision apparatus can be retained until again needed. A moveable magnet and an associated reed switch serves to deactivate the night vision device in the stowed position and enable activation of the night vision device in the operational position.

Claims

1. A mounting device for selectively mounting a night vision apparatus to a helmet, the helmet having an interior surface, an exterior surface and a peripheral edge, said mounting device comprising:

support means for supporting the night vision apparatus in a desired orientation;

clamping means, pivotably coupled to said support means, for selectively clamping onto the peripheral edge of the helmet above the eyes of a wearer, said clamping means including engaging means for engaging the interior surface and the exterior surface of the helmet with a releasable clamping action, said engaging means including at least one static surface for contacting the interior surface of the helmet and at least one moveable member for engaging the exterior surface of the helmet;

a pivot arm having a first end and a second end, said at least one moveable member being coupled to said first end of said pivot arm;

at least one lever having an end, said second end of said pivot arm being coupled to said end of said at least one lever, wherein movement of said lever in a first direction increases the clamping pressure provided by said at least one moveable member and said at least one static surface, and wherein movement of said lever in a second direction decreases the clamping pressure provided by said at least one moveable member and said at least one static surface, wherein said support means can be pivotably rotated about said clamping means to an operating position where the night vision apparatus is held in front of the eyes of the wearer, and a stowed position, wherein the night vision apparatus is held above the wearer'"'"'s field of view; and

locking means for selectively locking said support means in said stowed position.

2. The device according to claim 1, further including an adjustment means for adjusting the distance between the night vision apparatus and the eyes of the wearer when said support means is at said operational position.

3. The device according to claim 1, further including a stopping means for stopping said support means from pivotably rotating beyond said stowed position from said operational position.

4. The device according to claim 1, further including a retaining means for selectively retaining said support means at said operational position, thereby preventing any inadvertent movement of said support means away from said operational position.

5. The device according to claim 1, further including a disabling means for automatically disabling the night vision apparatus when said support means is moved away from said operational position.

6. The device according to claim 1, wherein said at least one static surface generally conforms to the shape of said interior surface of the helmet that said static surface engages.

7. The device according to claim 1, wherein said clamping means selectively clamps onto the helmet in a releasable and non-destructive manner, whereby said clamping means engages the helmet without requiring any modifications to the helmet.

8. The device according to claim 1, wherein said support means includes a connector for engaging and retaining the night vision apparatus and a elongated arm coupled to said connector, whereby said elongated arm is pivotably connected to said clamping means, thereby enabling the night vision apparatus to be pivotably rotated between said stowed position and said operating position.

9. The device according to claim 1, wherein said connector is positionally adjustable relative said elongated arm, thereby enabling the distance of the night vision apparatus and the eyes of the wearer to be adjusted when said connector retains the night vision apparatus at said operational position.

10. The device according to claim 9, wherein a magnet is disposed within said connector for enabling the night vision apparatus in said operational position and for disabling the night vision apparatus in said stowed position.

11. The device according to claim 8, wherein said elongated arm is pivotably attached to said clamping means at a hinge member that rotates with said elongated arm between said stowed position and said operational position.

12. The device according to claim 11, wherein said locking means includes a latch that selectively engages said hinge member at said operational position, thereby preventing said hinge member from rotating away from said operational position.

13. The device according to claim 11, wherein said hinge member engages said clamping means when at said stowed position, thereby preventing said hinge member from rotating beyond said stowed position from said operational position.

14. The device according to claim 10, wherein said magnet is free moving within a confined area within said connector, said magnet moving from a first location when the night vision apparatus is at said the operational position, to a second location when the night vision apparatus is at said stowed position, thereby causing the magnet to enable and disable the reed switch when at said operational and said stowed position, respectively.
