    • PROBLEM TO BE SOLVED: To provide a window open-close device capable of freely changing the degree of the window opening of a movable fitting section by the change of wind pressure such as the strength of a wind by an air-shot mechanism for a small number of parts. SOLUTION: In the window open-close device composed of the rocking open- close type movable fitting section, an operating means, a link mechanism 4 operated by the operating means and the air-shot mechanism 7 permitting the free movement of the movable fitting section, the operating means consists of a wire 31 arranged to the link mechanism 4 and a winding mechanism for the wire 31. In the window open-close device, the link mechanism 4 is composed of a lever 5 moved by the wire 31 and a return spring 53, a rotating arm 62 rotated by an urging by the lever 5 and a twisting arm 64 connecting both the rotating arm 62 and a bracket 23 for the movable fitting section through ball joints 63 and 65. In the window open-close device, the air-shot mechanism 7 consists of a play opening 71 formed between the lever 5 and the rotating arm 62. COPYRIGHT: (C)2003,JPO

    • PROBLEM TO BE SOLVED: To provide a window improved in wind pressure resistance by holding a sash in a closed position with simple structure while allowing easy opening/ closing of the sash by remote operation. SOLUTION: This window 1 is provided with a frame 2 provided at an opening of a building; a sash 3 openably/closably provided at the frame 2 in the indoor and outdoor directions; and an opening/closing mechanism 11 provided at the frame 2 to open/close the sash 3 by remote operation. The opening/closing mechanism 11 has a bendable operating arm 12 for opening/closing the sash 3. A connection part between the tip of the operating arm 12 and the sash 3 is provided with a movement allowing part 51 allowing the tip of the operating arm to move in a direction almost orthogonal to the opening/closing direction of the sash when the sash 3 is closed or in front of the closed position. The frame 2 is provided with an engagement receiving part 53 for holding the sash 3 in the closed position by engaging an engaging part 52 provided on the tip side of the operating arm, by the movement of the tip of the operating arm 12 at the movement allowing part 51.

    • PROBLEM TO BE SOLVED: To provide a window opening and closing device capable of forming an air-beating mechanism in the small number of components, freely varying an opening of a sliding door by wind pressure such as a wind or the like and obtaining a comfortable quantity of ventilation. SOLUTION: In the window opening and closing device comprised of the oscillation opening and closing type sliding door, a reciprocating operation means, a link mechanism 5 and the air-beating mechanism allowing free oscillation of the sliding door, the link mechanism is operated by the reciprocating operation means to have reciprocating members 46 and 46 making reciprocating motion, a pivoting arm 52 and a torsional arm 54 connecting the pivoting arm 52 to a bracket of the sliding door through ball joints 53 and 55, and the mechanism comprises a loose gap occurring between a driving pin 47 and an operating surface of the pivoting arm 52.
