Pivotal window latch
Abstract
Abstract A WINDOW LATCHING MECHANISM FOR A VERTICAL PIVOTAL WINDOW HAS AN ELONGATED LATCHING FINGER PIVOTALLY MOUNTED AT ONE END TO EACH OF THE SIDE RAILS OF THE STATIONARY WINDOW FRAME. A SLOT IS FORMED ON THE FREE END OF EACH FINGER FOR ENGAGING PINS SECURED TO THE SIDE RAILS OF THE PIVOTING WINDOW FRAME WHEN THE FINGER IS IN THE LATCHED POSITION. EACH FINGER IS LOCKED IN THE LATCHED POSITION BY A SPRING LOADED PIN SECURED TO EACH SIDE RAIL OF THE STATIONARY FRAME. THE FINGERS ARE UNLATCHED BY KEYS, ALLOWING THE PIVOTAL FRAME TO BE ROTATED ABOUT TWO VERTICAL PINS, ONE BEING CONNECTED BETWEEN THE TOP RAILS OF THE TWO FRAMES AND ONE BETWEEN THE BOTTOM RAILS. A SPRING LOADED SLANT PIN PROJECTS FROM ONE OF THE SIDE RAILS OF THE PIVOTAL FRAME AND ALLOWS THE FRAME TO BE ROTATED IN ONLY ONE DIRECTION. A SPRING LOADED SQUARE PIN PROJECTS FROM THE OTHER SIDE RAIL OF THE PIVOTAL FRAME SO AS TO LOCK THE FRAME IN THE 180* ROTATED POSITION.
