School bus window with single-action split-sash release mechanism

A school bus split-sash window comprised of:

• a first fixed pane;
• a second pane;
• movable with respect to the first fixed pane;
• a frame incorporating the second pane, the frame having a first side and having a second side opposite of the first side;
• a first spring-loaded latch positioned integral to the first side of the frame such that the first latch is held in a normally extended position relative to the frame;
• a second spring-loaded latch positioned integral to the second side of the frame such that the second latch is held in a normally extended position relative to the frame;
• a latch release bar movably positioned between a first stanchion and a second stanchion, the stanchions are integral to the frame;
• a first cable connecting the first spring-loaded latch to the latch release bar, so that a force, to be applied by an external means, applied to the release bar which moves the release bar between the first and second stanchions pulls the first cable partially around the first stanchion and causing the first spring-loaded latch to revert to an extended position with respect to the frame;
• and
• a second cable connecting the first and second spring-loaded latch to the latches release bar, so that the force applied to the release bar moves the release bar between the first and second stanchions thereby pulling the second cable partially around the second stanchion and causing the second spring-loaded latch to draw inward with respect to the frame, and the release of the force allows the second spring-loaded latch to revert to the extended position with respect to the frame.
