FIG. 1 is a longitudinal sectional view and an internal view of the open / closed state in which the window driving device 8 is installed. As shown in Figure 1, the window opening and closing system according to claim 1 comprises a window sash 2, a damper 4 that constantly applies an opening force to the sash 2 on a fixed frame 3, a window opener 5 installed on the fixed frame 3 that opens and closes the sash 2 by winding or unwinding a wire rope 6 connected to the sash 2, a window drive device 8 attached to the fixed frame 3 by a fixing fitting 96, and a drive shaft 7 that connects the drive shaft 81 of the window drive device 8 to the window opener 5. Furthermore, the window drive device 8 is installed on the fixed frame 3 on one side of the window such that the operating rod 86 and the pull handle grip 91 of the window drive device 8 face approximately vertically downward.

[0018] To open or close the shoji screen 2, the lever handle 92 provided on the pull grip 91 of the operating rod 86 of the window drive device 8 releases the closing lock, causing the operating rod 86 and pull grip 91 to be raised and the shoji screen 2 to open. To close it, the pull grip 91 is pulled down, and the shoji screen 2 is closed by the locking of a claw member built into the operating rod 86 when the shoji screen 2 is fully closed.

[0019] The window drive device 8 may be installed on the left or right side of window 1, or on the intermediate mullions of the connected windows of sash 2. Furthermore, when window 1 is set as a smoke vent window, when sash 2 is closed, the position of the lever handle 92 of the pull grip 91 of the operating rod 86 of the window drive device 8 should be 800 mm from the floor. mm It is required to be installed at a height of 1500mm or less. In addition, the damper 4 that provides the opening force to the above-mentioned shoji screen 2 may be a gas damper, spring stay, torsion bar, etc.

[0020] Figure 2 shows a partial vertical cross-sectional view and a side view of the window drive mechanism 8 (when the sash is closed). Figure 3 is a partial vertical cross-sectional view of the window drive mechanism 8 (when the sash is open). As shown in Figures 2 and 3, the window drive device 8 according to claims 1 and 2 comprises a drive shaft 81, a sprocket 84 fitted to the drive shaft 81, a roller chain 85 wrapped around the sprocket 84, a sprocket housing 82 that houses the sprocket 84 and the roller chain 85 and guides the rotation of the roller chain 85, an operating rod 86 connected to the end of the roller chain 85 by a connecting fitting 88, a long guide member 83 that guides the raising and lowering of the operating rod 86 and houses the fed-out roller chain 85, and a compression coil spring 87 between the guide member 83 and the roller chain 85, with the roller chain 85 connected to the operating rod 86 at its center.

[0021] The operating rod 86 of the window drive device 8 has a claw member 93 built into it. When the sash 2 is fully closed, the claw member 93 rotates and locks into the lower cover 90 of the guide member 83, thus maintaining the closed state of the sash 2. Furthermore, the lower end of the operating rod 86 is equipped with a pull handle grip 91 with a lever handle 92 for releasing the lock of the claw member 93, a connecting rod 94 that releases the lock of the claw member 93 built into the operating rod 86 when the lever handle 92 is rotated, and a spring 95 that lifts the connecting rod 94 so that the claw member 93 can rotate at all times. The operating rod 86 may also be formed in a round shape or a polygon such as a hexagon.

[0022] Furthermore, the claw member 93 is provided with an elongated hole 98 that guides the claw member 93 to rotate around the claw member pin 97 when it engages with the pin of the interlocking rod 94 by the linear movement of the interlocking rod 94 pushed up by the lever handle 92.

[0023] Furthermore, the sprocket housing 82 is positioned tangentially to the sprocket 84 so that the roller chain 85 and the operating rod 86 are efficiently pulled down within the guide member 83, and the guide member 83 is minimized by bringing the fed-out roller chain 85 closer to parallel with the roller chain 85 connected to the operating rod 86.

When the sliding door 2 is opened, the compression coil spring 87 rises simultaneously with the roller chain 85 and the operating rod 86, and the compression coil spring 87 comes into contact with the stopper at the upper end of the guide member 83. Further compression occurs until the compression coil spring 87 is in a tight fit, stopping the upward movement of the operating rod 86. As a result, the operating rod 86 is subjected to a force that attempts to close the sliding door 2, which is opposed to the opening force of the sliding door 2 due to the compression of the compression coil spring 87. This reduces the opening force of the sliding door 2, suppresses the impact when the sliding door 2 is opened, and makes the downward operation of the operating rod 86 easier when closing, thus facilitating the opening and closing of the sliding door 2.

[0025] Furthermore, a highly sliding bearing may be provided between the operating rod 86 and the guide member 83, and in addition, a shock-absorbing material such as rubber may be installed at the stopper portion of the upper end of the guide member 83 where the compression coil spring 87, which rises when the sliding door 2 is opened, comes into contact.

[0026] Furthermore, since the roller chain 85 and compression coil spring 87 of the window drive device 8 are housed within the sprocket housing 82 and guide member 83 and are not exposed to the outside, malfunctions due to the accumulation of dirt or corrosion such as rust are reduced. Also, as shown in the AA cross-section of Figure 3, the guide member 83 is a preferred example made of aluminum extruded material, which is rigid, lightweight, and highly corrosion-resistant. In addition, if the strength and other conditions are met, a ball chain or a chain-like chain may be used instead of the roller chain 85 of the drive device 8.
