  • Lens cover assembly for a folding camera
    Patent number: 6527461
    Abstract: A lens cover assembly for a folding camera includes a main frame assembly and a lens assembly pivotally mounted on the main frame assembly and movable between a closed position in which the lens assembly is disposed at least in part within the main frame assembly and an open position in which the lens assembly upstands from the main frame assembly, the lens assembly having a lens therein. A lens cover member is pivotally mounted on the lens assembly and is movable between a first position in which the lens cover member completely covers the lens, and a second position in which the lens cover member is removed from the lens. A mechanical linkage interconnects the main frame assembly and the lens cover member and is operative, upon moving the lens assembly from the closed position to the open position, to move the lens cover member to the second position, and further operative, upon moving the lens assembly from the open position to the closed position, to move the lens cover member to the first position.

  • Electronic flash apparatus with extendable on/off switch control apparatus
    Patent number: 4085414
    Abstract: An electronic flash unit attachable to the top of a camera shutter housing is provided with switch control apparatus which may be selectively extended into position so as to be engaged by the photographer when holding the camera in its normally expected manner. Engagement of the switch control apparatus by the photographer causes it to effect the closing of an ON-OFF switch thereby applying power to the flash unit whereas subsequent disengagement of the switch control apparatus causes it to automatically effect the opening of the ON-OFF switch.
