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;
wherein said head is mounted on a surface of said receptacle, said head having a flat surface generally parallel to said surface of said receptacle and said head further having a ramp surface extending from said flat surface toward said surface of said receptacle.

-
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; wherein each of said heads has a flat surface generally parallel to said one of said surfaces of said receptacle and wherein said second surface of said head is an inclined surface extending from said flat surface toward said one of said surfaces of said receptacle. - View Dependent Claims (6, 7)
