ABSTRACT:
Turnable window arrangement with a casement connected to a window frame by means of two oppositely directed pivot pins at one end of the casement which is uppermost when the latter is in its normal closed position. The pivot pins slidably engage their respective associated guide grooves in the window frame to permit this one end of the casement to be displaced to selected pivotal positions between upper and lower ends of the frame. The pivot pins are also displaceable in the casement in a direction substantially parallel to the height dimension of the casement, namely parallel to the longitudinal axis of the vertical side portion of the casement. Link arm mechanisms are arranged on their respective opposite sides of the casement for the support of the latter in the window frame at the selected pivotal positions.
