FIG. 24 is a sectional view taken along line J-J in FIG.
A driving device for geared cables 28 and 29 is shown. Gear 7 is attached to geared cables 28 and 29.
A square portion of a shaft 75 is fitted into a square center hole of the gear 74 and is locked therein. axis 75
Case 76 and case 7 fixed to case 76
7 and a hole in a cover 78 fixed to the case 77, and a worm wheel 79 (helical gear shown) is fixed to the shaft 75. A shafted worm 81 is engaged with the worm wheel 79 and is supported by the cover 78 so as to be prevented from moving in the axial direction.
Although not shown, a handle can be inserted into the shaft end of the shafted worm 81. Alternatively, a power drive mechanism is connected.

To install the drive mechanism of the guide wheel device 4, the drive device 7 is fixed to the lower frame 36, and the guide pipes 72, 73 are attached from the drive device 7 to the groove 12 in the vertical frame 8. The guide pipe and the ends of the geared cables 28 and 29 placed in the groove 12 are fixed to the slide 58, respectively.

When the internal shoji 3 is lifted from the closed state of the window, the tensile force applied to the band 61 via the stopper 62 is loosened. Since the external shoji 2 is constantly energized by gravity, the adjustment band 61 is pulled through the stopper 62 on the side of the external shoji 2, and the guide wheel 48 that is wrapped around it rotates around the shaft 52 and adjusts. The contact portion with the band 61 is changed sequentially. The strap 61 is rolled along the protrusion 23. That is, the guide wheel 48 can be seen as a rolling circle, and the tuning band 61 can be seen as a rolling surface.
On the other hand, since the adjustment band 61 is locked to the lower end of the protrusion 23, ie, the lower part of the external shoji 2, through the stopper 62, there is no relative movement between the external shoji 2 and the adjustment band 61 in the vertical direction. In the state shown in FIG. 3, openings are made at the top and bottom by a quarter of the opening. When the internal shoji 3 is pulled down, the external shoji 2 is pulled up.

This section describes the case of opening a window to quickly escape or exhaust smoke in the event of an emergency.

When the shafted worm 81 is rotated manually or by power in the state shown in FIG. 3, the worm wheel 79 rotates and the coaxial gear 74 rotates. Geared cables 28, 29 move in opposite directions.
That is, when the geared cable 28 moves to the right when viewed from the inside of the drive device 7, the geared cable 29 moves to the left, and when the geared cable 28 moves to the left, the geared cable 29 moves to the right.
When the geared cable 28 goes to the right and the geared cable 29 goes to the left, the geared cables 28, 2
9 slide in the guide pipes 72 and 73, respectively, enter the groove 12, and rise together. The slide 58 rises and therefore the guide wheel arrangement 4 rises. A stopper 62 is attached to the lower end of the adjustment band 61 wrapped around the guide wheel 48.
Both the external shoji 2 and the internal shoji 3 are pulled up in a suspended manner through the shoji 3, and the exit door shown in FIG. 5 is formed. Conversely, when the shafted worm 81 is energized in the opposite direction, the geared cable 28 moves to the left, the geared cable 29 moves to the right, the guide wheel device 4 descends, and both the external shoji 2 and the internal shoji 3 descend. The state will be as follows. When the shafted worm 81 is further rotated in the same direction, the guide wheel device 4 is further lowered to the state shown in FIG. 6. FIG. 1 shows an opening that can effectively exhaust smoke. From this state, when the shafted worm 81 is energized so that the geared cable 28 moves to the right and the geared cable 29 moves to the left, the guide wheel device 4 is pulled up, and both the external shoji 2 and the internal shoji 3 are pulled up, as shown in FIG. Return to state.

Although the above explanation of quickly escaping or smoke evacuation in an emergency has been based on the state shown in Figure 3, the situation shown in Figure 2 or between Figures 2 and 3, or the state shown in Figure 4 The state shown in FIGS. 5 and 6 can also be obtained from the state in which the external shoji 2 and the internal shoji 3 are present.

In the state shown in FIG. 2, the shafted worm 81 is rotated to raise the guide wheel device 4 (the action is similar to that described in the third section above).
(Same as when driven from the state shown in the figure), the adjustment band 61 is pulled up by the guide wheel 48, but since the external shoji 2 is already at the rising end and in contact with the upper frame 31, it cannot rise, so only the internal shoji 3 It is pulled up by the tension belt 61 and becomes in the state of the escape port, that is, FIG. 5. When the shafted worm 81 is reversely energized, the guide wheel device 4 descends, and as a result, the external shoji 2 and the internal shoji 3 descend while being stacked on top of each other, resulting in the state shown in FIG. 3.

In the state shown in FIG. 2, when the shafted worm 81 is rotated to lower the guide wheel device 4, the guide wheel 48
The adjustment belt 61 between the inner shoji 3 and the outer shoji 2 is loosened, and the outer shoji 2
The tension band 61 between the guide wheel 48 and the guide wheel 48 is pulled by the gravity of the external shoji 2, and the external shoji 2 is lowered to be in the smoke exhausting state, that is, as shown in FIG. In this case as well, when the guide wheel 4 is raised, the state shown in FIG. 3 is achieved.

When the outer shoji 2 and the inner shoji 3 are open in the state between FIG. 2 and FIG. The upper stile 33 of the outer shoji 2 first comes into contact with the upper frame 31, and the inner shoji 3 is subsequently pulled up by the belt 61, resulting in the state shown in FIG. 5. . When the guide wheel device 4 is lowered, it will be in the state shown in FIG.

When the outer shoji 2 and the inner shoji 3 are open in the state between FIG. 2 and FIG. The lower stile 38 of the inner shoji 3 first contacts the lower frame 36, and then the outer shoji 2 descends while pulling the strip 61 due to gravity and moves down to the sixth position with the window open in the middle. It will be in the state shown in the figure. When the guide wheel device 4 is raised, it will be in the state shown in FIG.

As shown in FIG. 4, when the guide wheel device 4 is raised or lowered from the glass cleaning state due to overtravel, the outer shoji 2 and the inner shoji 3 rise or fall while maintaining their relative positions, and the inner shoji 3
first comes into contact with the upper frame 31 or the external shoji 2
first contacts the lower frame 36, and then the external shoji 2
is raised, or the internal shoji 3 is subsequently lowered, resulting in the state shown in FIG. 5 or 6.

As shown in the above actions, even when the external shoji 2 and the internal shoji 3 are in either state (excluding cases where they are already in the states shown in Figures 5 and 6), the shafted worm 81 is activated in case of an emergency. By rotating the , an escape port is configured and a smoke exhaust port is formed.

FIGS. 25 and 26 are interior views of windows, respectively, showing other embodiments. 25 and 26 show a case where the window width is narrow and the same geared cable, its driving device, and guide wheel device as in the previous embodiment are provided. 29, their free ends extend from the drive device 7 to the end of the lower frame in FIG. 26, and their free ends slightly protrude from the drive device 7 in FIG. Therefore, the 25th
In the figure, the geared cable 28 is only allowed to run to the right and the geared cable 29 is only allowed to go to the left in the drive unit 7, so the guide wheel device 4 can only move upward, so that the lower half of the window can be opened. In other words, it is an escape port type. In FIG. 26, the geared cable 28 is only allowed to run to the left and the geared cable 29 is only allowed to go to the right in the drive unit 7, so the guide wheel device 4 can only be lowered and the upper half of the window can be opened. That is, it is a smoke exhaust type.

FIGS. 27 and 28 are interior views of windows showing still other embodiments. FIG. 27 and FIG. 28 each show the driving device 7 provided in a vertical frame.
FIG. 27 shows a smoke exhaust type, and when the gear 74 rotates counterclockwise as shown, the geared cable 28 goes down and the geared cable 29 goes up. Although details are not shown, the geared cable 29 passes through the vertical frame and the upper frame and is connected at its end to the guide wheel device 4 in the opposite vertical frame. Therefore, the guide wheel device 4 sliding in the left and right vertical frames descends. Figure 28 shows an escape port type. When the gear 74 rotates clockwise as shown, the geared cable 28 goes up and the geared cable 29 goes down. The geared cable 29 passes through the vertical frame and the upper frame and is connected to the guide wheel device 4 in the vertical frame on the opposite side, as in FIG. 27. Therefore, the guide wheel devices 4 that slide in the left and right vertical frames rise together to open the external shoji 2 and the internal shoji 3.
will rise together. In other words, it is an escape port type.

As described above, according to the opening/closing mechanism of the lift/lower window of the present invention, the upper half of the window can be opened and the lower half can be opened to the smoke exhaust port to serve as an escape port. For normal ventilation, the inner and outer shoji screens operate simultaneously to create openings at the top and bottom. Since the space of the upper frame and vertical frame is small, the effective opening can be made large. This is particularly advantageous for replacement mats with old frames.
