Sliding door fastener
Abstract
Abstract A LOCKING DEVICE IS DISCLOSED FOR A SLIDING DOOR STRUCTURE OR DOOR WALL WHICH COMPRISES A PAIR OF ELONGATED BARS, ONE BAR IS HINGED TO THE END OF THE OTHER AND BOTH ARE ENGAGABLE WITH THE LOWER RAIL OF A DOOR WALL IN THE PATH OF MOTION OF A SLIDABLE GLASS PANEL. THE TWO BARS HAVE AN OVERALL, UNFOLDED LENGTH WHICH CORRESPONDS TO THE DISTANCE BETWEEN THE PANEL AND ONE OF THE FRAME STILES WHEN THE PANEL IS ADJACENT THE OTHER STILE IN ITS CLOSED POSITION, SO THAT WHEN ENGAGED WITH THE RAIL BEHIND THE PANEL THEY FORM AN OBSTRUCTION WHICH PREVENTS THE PANEL FROM BEING OPENED. WHEN THE SHORTER OF THE TWO BARS IS PIVOTED WITH RESPECT TO THE OTHER BAR, THE PANEL CAN BE PARTIALLY OPENED TO PROVIDE A LIMITED ACCESS OPENING.
