摘要： A multi-position window capable of being either in a locked position with the window closed, a tilt-in position, with the top portion of the window open for ventilation purposes and the like, and in a swung-open position to permit the window to be easily cleaned. The position of the window is selected by controlling a handle member which drives a train mechanism to engage selected engageable members for achieving the desired position. A key operated lock member is provided to prevent unauthorized persons from swinging the window open.
