Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a door opening and closing device capable of retractably moving a latch and three-point fastening locking the device merely by the operation of one knob part without installing an separate cremorne lock. SOLUTION: When a handle 20 is turned, a cam plate 14 is rotated and drive groove paths 14', 14A', and 14B' are also displaced in circumferential direction so as to forcibly move communicating projected parts 12', 13A', and 13B' engaged with the drive groove paths 14A', 14A', and 14B' in the radial direction of a latch plate. By this, connecting rods 13A and 13B to which a latch metal fitting 12 and a dead lock member are connected are pushed in and out from a latch receiver and a connecting rod receiver.  A door can be brought under an openable state in which both the latch metal fitting and dead lock member are disengaged by the rotating angle of the handle 20, under an unlock closed state in which only the metal fitting of the latch is engaged with the latch receiver, and under a lock closed state in which both the latch metal fitting and dead lock member are engaged with receiving parts.
