First Claim
Patent Images
1. A helmet mount for night vision apparatus:
- said apparatus including a night vision goggle intensifying low level light into a visible image, a receptacle, and a mounting arrangement attached to said goggle and releasably coupled to said receptacle, said mounting arrangement being rotatable on said receptacle between operative and inoperative positions of said goggle; and
a stop arrangement including a spring loaded head biased toward a first position in the path of rotation of said mounting arrangement, said head having a first surface that obstructs rotation of the mounting arrangement from the inoperative to the operative position of said goggle, said head having a second surface that cooperates with said mounting arrangement to push said head to a second position that permits the rotation of said mounting arrangement between the goggles operative and inoperative positions.

Abstract
A helmet mount for night vision apparatus including a night vision goggle rotatable between operative and inoperative positions. Retractable stop means are included on the mount for obstructing the rotation of the goggle from its inoperative to operative position without obstructing the rotation of the goggle from its operative to its inoperative position.

6. A helmet mount for night vision apparatus;
-
said apparatus includes a night vision goggle intensifying low level light into a visible image and a goggle mount carrying said goggle, said goggle mount including a pair of coaxial plungers;
a receptacle having a pair of surfaces each of which has a socket that cooperates with one of said plungers whereby the mounting arrangement is rotatably mounted to said receptacle for rotating said goggle between its inoperative and operative positions; anda stop arrangement including a pair of spring loaded heads, each of said heads being located on one of said surfaces of said receptacle, each of said heads being biased to a first position spaced from its associated surface and having a first surface that cooperates with a first surface of said goggle mount to obstruct the rotation of said mount from the goggle'"'"'s inoperative to operative position, each of said heads having a second surface that cooperates with a second surface of said goggle mount to push said head to a second position adjacent its associated surface whereby said first surfaces do not obstruct the rotation of said mount from the goggles inoperative to operative positions. - View Dependent Claims (7, 8, 9)

11. A helmet mount for night vision apparatus:
-
said apparatus including a night vision goggle intensifying low level light into a visible image and a power pack providing electric power operating said goggle; said mount including a support band having an inner surface configured to seat on the front surface of a helmet and adapted to be fixed thereto and a pair of spaced apart ears extending from the outer surface of the support band in a generally forward direction, each ear containing a socket on the surface facing the adjacent surface of the other ear for coupling said power pack to and from said support band; a receptacle carried on said power pack, said receptacle having a second set of spaced apart ears extending in a generally forward direction, each of said ears in said second set having a socket on adjacent surfaces for rotatably coupling said mount for rotation between an inoperative and an operative position of said goggle; a stop arrangement including a pair of spring loaded heads, one of which is located on an adjacent surface of one of said second set of ears, each of said heads being biased to a first position spaced from its associated said adjacent surface, each head further having a flat surface generally parallel to its associated said adjacent surface, an inclined surface extending from said flat surface toward its associated said adjacent surface and an edge surface extending across said flat surface and said inclined surface; and
,said mount having a first surface that cooperates with said edge surface to obstruct the rotation of said mount from the goggle'"'"'s inoperative position to its operative position, said mount having a second surface that rides along said ramp as the mount is rotated from the goggle'"'"'s inoperative position thereby pushing said head from its first position to a second position wherein the head abuts its associated said adjacent surface, said second surface of said mount being on said flat surface when said goggle is in its operative position.
