Abstract: A foldaway casement type window crank handle assembly (10) which utilizes a spring member (50) for retaining the window crank handle (i.e., crank arm 20 and hand grip knob 23) in the extended operating position. The handle assembly is made up of a base member (11) which is mounted to a window frame (40) and houses the window drive mechanism. The base member (11) includes a top surface recess (17) with an aperture (16) therethrough into which the drive shaft (41) of the window mechanism is inserted. A cap member (30) is mounted onto the window drive shaft (41). A crank arm (20) includes a cavity region (24) along the center for receiving the cap member (30). The crank arm (20) is pivotal relative to the cap member (30) about a pivot joint (35) positioned at one end of the cavity region (24).
