Abstract
Abstract A foldable camera comprises a movable frame interconnected with components including the front element of a compound viewfinder, and a lens/shutter assembly. Also included is a built-in flash unit pivotal through a ninety degrees arc between a horizontal storage position in a recess provided in the camera's encasement, to a vertical, use position. The camera is also furnished with biasing means for extending and retracting the frame between its use and storage positions. The biasing means for extending the mount comprises a pivotal actuating lever having camming slots adapted to receive follower pins located on the flash unit. Pivoting of the flash unit into its use position results in the camming of the lever, urging it against the mount, and causing the latter to move toward the camera's front, thereby extending the lens/shutter assembly and moving the viewfinder element into the recess. Biasing means for retracting the mount comprises springs extending between the mount and the rear of the camera which become operative when the flash unit is pivoted back into the recess, thereby camming the lever away from the mount and allowing positional reversing of the lens/shutter assembly and the front viewfinder element.

147 words
A camera including a camera housing, a flash unit movable between a use position wherein the flash unit extends from the housing and a storage position wherein the flash unit is in the housing, a lens/shutter assembly and a viewfinder, characterized in the improvement comprising: a movable mount carrying at least part of said lens/shutter assembly and a front component of said viewfinder, said mount being movable between a storage position for protecting the front lens/shutter assembly and an active position for presenting said lens/shutter assembly and said front component for photographic use; and mount-biasing means for biasing said mount from the storage position to the active position in response to the movement of said flash unit into the use position, and for biasing said mount from the active position to the storage position in response to the movement of said flash unit into the storage position.
Claim 3
Dependent Claim
78 words
A camera according to claim 1 wherein movement of the flash unit includes pivoting of the flash unit between the use and the storage positions, characterized in that the flash unit has first camming means and said mount-biasing means has second camming means for cooperating engagement with said first camming means, said first camming means engaging said second camming means to move said mount-biasing means to the use position when the flash unit pivots to its use position.
Claim 4
Dependent Claim
72 words
A camera according to claim 2 said first camming means comprises camming followers in the flash unit, and said mount-biasing means comprises a pivotal actuating lever having said second camming means, said second camming means including camming slots in said lever for receiving said camming followers, said followers urging said lever to move said mount to the active position in response to the pivoting of the flash unit to the use position.
Claim 5
Dependent Claim
21 words
A camera according to claim 2 said mount-biasing means further comprises spring means for urging said mount toward the storage position.
Claim 6
Dependent Claim
25 words
A camera according to claim 4 wherein said spring means comprises at least one helical spring connected to said mount and to the camera housing.
Claim 7
Dependent Claim
57 words
A camera according to claim 1 wherein the camera is provided with an encasement having a recess dimensioned to separately receive both said flash unit and said viewfinder front component, said recess receiving the viewfinder when said mount moves to its storage position and receiving the viewfinder front component when said mount moves to the active position.
Claim 8
Dependent Claim
13 words
A camera according to claim 1 wherein said mount carries a light baffle.
Claim 9
Dependent Claim
22 words
A camera according to claim 1 in which said mount comprises a lens/shutter housing for at least partially enclosing said lens/shutter assembly.
Claim 10
Dependent Claim
15 words
A camera according to claim 1 wherein said movable mount moves along a linear axis.
Claim 11
Dependent Claim
