ABSTRACT:
An erecting linkage and cover assembly for collapsible bellows-type cameras having a lens supporting shutter housing movable between erected and closed positions with respect to a camera body. The erecting linkage includes a pair of folding linkage sets connected between the camera body, the housing and a pivotal cover and operable in a manner to retain the lens supporting shutter housing positively in the erected condition of the camera. The linkage is associated with the shutter housing by way of an adjustable locating frame in a manner such that accurate calibration of shutter housing and thus lens orientation with respect to the camera body is facilitated. Also, the cover is provided with a latch arrangement by which the cover is releasably retained in a closed position overlying the shutter housing and lens against the front of the camera body. The latch means further operates to initiate movement of the erecting linkage from its erected condition to its folded condition.
