One-piece light cone baffle

Claim 2

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.

Claim 3

The light cone baffle of claim 1 wherein said integral connecting means comprises a plurality of hinges integrally connected to said member and said walls, each of said walls being integrally connected to said member by at least one of said hinges and each of said hinges resiliently biasing its respective wall toward said relaxed position.

Claim 4

The light cone baffle of claim 1 wherein each of said walls is shaped to engage each of the adjacent walls to form a substantially light tight seal when said walls are in said operative position.

Claim 5

The light cone baffle of claim 1 wherein said reflecting means includes ridges integrally formed on said walls.

Claim 6

The light cone baffle of claim 1 wherein said securing means includes a protrusion on one of said walls, said protrusion being adapted to engage a notch in the camera.

Claim 7

The light cone baffle of claim 1 wherein said member further comprises a protrusion adapted to engage a groove in the camera to properly locate said baffle within the camera.

Claim 8

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.

Claim 9

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.
