ABSTRACT:
A foldable film winding crank for a camera comprising a rotary base, and a two-part handle having a first handle part pivotably connected to the base and a second handle part pivotably connected to the first handle part to permit the two-part handle to be folded lengthwise into a cavity in the base for storage and to be unfolded lengthwise from the cavity to be manually grasped in order to rotate the base for film winding, is characterized in that a pivotable connection between the first handle part and the base and a pivotable connection between the second handle part and the first handle part are located at respective sides of an axis of rotation of the base to initially allow the second handle part to be foldingly pivoted in one direction to the first handle part and then allow the first handle part to be foldingly pivoted together with the second handle part in an opposite direction into the cavity and, conversely, to initially allow the second handle part to be unfoldingly pivoted from the first handle part in one direction and then allow the second handle part to be unfoldingly pivoted from the cavity in an opposite direction. This allows the cavity to be made relatively shallow.
