Abstract
A one-piece light cone baffle for use in a camera comprising a frame and four walls integrally connected to the frame. The frame has centrally located therein a light-transmitting window. Each of the walls is connected to the frame by a hinge and is movable between a relaxed position extending outwardly from the frame and an operative position in which the walls cooperate to form a light tight seal. Means are also provided for reflecting non-image-forming light passing through the window away from a light-sensitive material and for securing the baffle in place in the baffle recess of the camera.
Claims7
A light cone baffle for use in photographic apparatus containing a light-sensitive material, said baffle comprising:
- a member defining a light-transmitting window;
- a plurality of walls;
- means for integrally connecting said member with each of said walls so that said walls are movable between a relaxed position and an operative position;
- means positioned on said walls when in said operative position for reflecting non-image forming light passing through said window away from the light-sensitive material;
- and
- means for securing said baffle in place in the photographic apparatus with said walls in said operative position.
A light cone baffle for use in a camera containing a film, said baffle comprising:
- a frame defining a light-transmitting window;
- a plurality of walls;
- means for integrally connecting said walls to said frame for movement between a relaxed and an operative position, said means comprising a plurality of hinges integrally connected to said frame and said walls, each of said walls being integrally connected to said frame by at least one of said hinges and each of said hinges resiliently biasing its respective wall toward its relaxed position;
- ridges integrally formed on said walls and positioned, when said walls are in said operative position, to reflect non-image forming light passing through said window away from the film;
- a protrusion on one of said walls adapted to engage a notch in the camera to retain said baffle with said walls in said operative position within the camera;
- and
- a protrusion on said frame adapted to engage a groove in the camera to align said baffle within the camera.
