Abstract

A mount for monocular enhanced night vision goggles having an ocular preference adjustment, an interpupillary adjustment, an eye relief adjustment, a tilt adjustment, a vertical adjustment, a quick stowage feature and a flip-up stowage feature is disclosed. An apparatus in accordance with the present invention has a housing secured to headgear. A vertical block is slidably coupled to the housing allowing it to translate vertically. A chassis is rotatably coupled to the vertical block allowing it to rotate between an in-use and flip-up position. A monorail is rotatably coupled to the chassis allowing it to rotate between an in-use and a quick stowage position. A carriage is slidably coupled to the monorail allowing for an eye relief adjustment. Enhanced night vision goggles are attached to a socket assembly which is movably coupled to the carriage allowing relocation in front of either eye while facing the same direction.

Claims

1. A mount for night vision goggles, the mount comprising:

a housing adapted to secure the mount to headgear;

a vertical block slidably coupled to the housing, wherein the vertical block can be translated in a vertical movement with respect to the housing through a vertical adjustment knob that is in communication between the vertical block and housing;

a chassis rotatably coupled to the vertical block, wherein the chassis is rotatable about a chassis rotation axis between an in-use position and a flip-up stowage position wherein the chassis rotation axis is substantially perpendicular to the vertical movement of the vertical block;

a monorail rotatably coupled to the chassis, wherein the monorail substantially extends longitudinally from the chassis and wherein the monorail rotates about a longitudinal axis such that the monorail can be rotated between the in-use position and a quick stowage position;

a carriage slidably coupled to the monorail, wherein the carriage has a carriage lumen adapted to slidably receive the monorail and wherein the carriage slides transversely along the longitudinal axis of the monorail providing an eye relief adjustment movement; and

a socket assembly coupled to the carriage wherein the socket assembly has a night vision goggle attachment feature whereby the night vision goggles can be secured to the socket assembly.

2. The mount of claim 1, wherein the socket assembly is movably coupled to the carriage such that the socket assembly may be relocated on an opposite side of the carriage and remain facing the same direction thereby allowing the night vision goggles to be utilized for the in-use position with both a left and right eye of a user.

3. The mount of claim 2, wherein the socket assembly further comprises an upper socket, a lower socket, and an interpupillary adjustment lever wherein the upper socket and lower socket are slidably coupled together and wherein the interpupillary adjustment lever is coupled to the upper socket and lower socket such that an adjustment of the interpupillary adjustment lever slidably translates the lower socket with respect to the upper socket thereby providing an interpupillary adjustment movement, and wherein the lower socket includes the night vision goggle attachment feature whereby the night vision goggles can be secured.

4. The mount of claim 3, further including a pivot lever coupled to the chassis in communication between the vertical block and chassis such that movement of the pivot lever rotates the chassis about the chassis rotation axis to a fine degree of resolution providing a tilt adjustment feature.

5. The mount of claim 4, further including a carriage stop connected to the carriage and in communication with the monorail such that the carriage stop may be disengaged to allow the carriage to transversely slide along the monorail, and thereafter the carriage stop may be engaged securing the carriage in a stationary position relative to the monorail.

6. The mount of claim 5, further including a swing link having a first and second end, wherein the first end is rotatably coupled to the carriage and the second end is rotatably coupled to the upper socket, wherein the upper socket may rotate about the second end of the swing link along a swing plane while simultaneously the first end of the swing link rotates about the chassis along the swing plane such that the upper socket remains in a forward facing orientation thereby allowing an ocular preference selection between the left and right eye, wherein the swing plane is parallel to both the interpupillary adjustment movement and the eye relief adjustment movement.

7. The mount of claim 6, further including a socket assembly lock coupled to the upper socket which may be in direct communication with the carriage such that the socket assembly lock securely affixes the upper socket in a locked position with respect to the carriage to prevent an accidental movement of the upper socket once an ocular preference has been established.

8. The mount of the claim 7, wherein the socket assembly lock is comprised of a threaded rod with a lock shaft wheel and wherein the upper socket is further comprised of two narrow extrusions, each with a hole, thereby allowing the threaded rod to slide and rotate within the holes, and wherein the carriage is further comprised of threaded receptacles on opposite sides configured to accept the threaded rod such that the threaded rod may be threaded into the threaded receptacles thereby securing the upper socket assembly in either opposite side of the carriage.

9. The mount of claim 8, wherein the housing is secured substantially along a centerline of the helmet, wherein the housing comprises a tongue, a lock, a lock spring and an actuator, wherein the tongue is located at one end of the housing and is adapted to fit into a first mount recess in the helmet and wherein the lock and lock spring are slidably coupled to the housing at the other end such that the lock will become secured against a second mount recess in the helmet when force is used to overcome the lock spring thereby holding the housing stationary in relation to the helmet and wherein the actuator is movably coupled to the housing such that movement of the actuator compresses the lock spring releasing the lock to allow removal of the housing from the helmet.

10. The mount of claim 5, further including a shuttle having a first and second end, wherein the first end is slidably coupled to the carriage and the second end is slidably coupled to the upper socket, wherein the shuttle may slide along a shuttle axis from the first end to second end while the upper socket may slide along the shuttle axis from the second end to the first end such that the upper socket remains in a forward facing orientation thereby allowing an ocular preference selection, wherein the shuttle axis is parallel to the interpupillary adjustment movement.

11. The mount of claim 5, further including a rotation link having a first and second end, wherein the first end is rotatably coupled to the carriage and the second end is rotatably coupled to the upper socket, wherein the upper socket may rotate about the second end of the swing link along a rotation plane while simultaneously the first end of the rotation link rotates about the chassis along the rotation plane such that the upper socket remains in a forward facing orientation thereby allowing an ocular preference selection, wherein the rotation plane is parallel to the interpupillary adjustment movement and perpendicular to the eye relief adjustment movement.

12. A mount for night vision goggles, the mount having an eye relief adjustment means, the eye relief adjustment means comprising:

a monorail having a longitudinal axis, the monorail extending from the mount along the longitudinal axis; and

a carriage slidably coupled to the monorail, wherein the monorail is rotatable about the longitudinal axis to rotate the carriage relative to the mount;

wherein the carriage has a carriage lumen configured to slidably receive the monorail and wherein the carriage slides traversely along the longitudinal axis of the monorail to provide an eye relief adjustment movement.

wherein the eye distance relief lever has a disengaged state wherein the eye distance relief lever is not in contact with a notch, allowing the carriage to slide along the monorail;

and

wherein the eye distance relief lever has an engaged state wherein the eye distance relief lever is received in a notch, to prevent the carriage from sliding with respect to the monorail.

14. The mount of claim 12, wherein the monorail is rotatable about the longitudinal axis between a use position and a stowage position.
