Abstract
A helmet mount for a night vision device is provided having means to attached to headgear, such as a helmet, wherein the mount is rotatable between a use position and a stowed position about an axis that is substantially parallel to the attachment means. In one embodiment, a position adjustment assembly comprises a rotary plate, a helmet block rotationally coupled to the rotary plate and a spring-biased ball and socket system located between the helmet bock and rotary plate. In another embodiment, a tilt adjustment assembly may include a gear system wherein rotation of a lever produces rotation of a night vision device relative to a user's eyes.
Claims15
A rotatable mount for a night vision device having means to attach to headgear wherein the mount is rotatable about a point in front of the headgear and above the line of sight of the user between a use position and a stowed position in a circular motion within a plane which is generally tangential to a point of attachment of the night vision device and the headgear.
A rotatable mount for a night vision device having means to attach to headgear wherein, in a stowed position, an eyepiece of the night vision device is substantially flush with the headgear.
A rotatable mount for a night vision device having means to attach to headgear wherein, in a stowed position, the center of gravity of the night vision device is substantially directly above the attachment means and an eyepiece of the night vision device is directed toward the headgear.
A position adjustment assembly adapted for rotatably attaching a night vision device to a helmet, the position adjustment assembly comprising:
- a rotary plate;
- a helmet block rotationally coupled to the rotary plate in a circular motion within a plane which is generally tangential to a point of attachment of the night vision device and the headgear;
- and
- a spring-biased ball and socket system located between the helmet block and rotary plate including at least one socket, at least one spring and at least one ball biased against the rotary plate by the corresponding spring.
A tilt angle adjustment assembly adapted for use in a rotatable helmet mount for a night vision device, the tilt angle adjustment assembly comprising:
- a lever having a gear head attached thereto;
- and a receiving gear wherein rotation of the lever causes the gear head to rotate with respect to the receiving gear to produce a rotation of the night vision device relative to a user's eyes.
