Although FIG. 1 shows a state in which a plurality of sets of isolation/latching devices constructed in this manner are attached to the vertical stile 16 of the second window via the substrate 34, it is possible to use one set as the case requires. Further, although the sliding plate 35 is provided in the embodiment, this is omitted and the actuating plate 38 is used instead.
You can also operate it by moving it.

The operation of the present invention will be explained below.

In FIGS. 9 to 11, the pinion 24
When the handle attached to the handle is rotated clockwise, the upper and lower rack members 25A and 25B move in directions A and B, respectively. Above upper and lower rack members 25A and 2
The movement of 5B in directions A and B is transmitted by members 31 and 31 to the isolating and latching device. In this device, when the sliding plate 35 is vertically pulled down by the connecting member 31, the actuating plate 38 formed integrally with the sliding plate 35 is similarly pulled down. This movement causes the bending portion 4 of the bending guide groove 44 of the actuating plate 38 to
4B guides the rotation pin 40A of the cam plate 40, and the cam plate 40 protrudes to the right as shown in FIG. The curved free end of the cam plate 40 is the abutment plate 42
The second window 7 is moved from the first window 5 toward the room by the reaction force. During the above movement, the guide pin 20 attached to the second window 7 is pushed up obliquely in the guide groove 18, so that the first window 7
The second window 7, which is separated from the original position, will be located above the original position.

At the same time, as the lower rack member 25B moves in the direction B, the pin 27 slides within the Z-shaped groove 28 and pushes the grooved cam 29 downward (FIG. 11). The depressed grooved cam 29 comes into contact with the receiver 30 fixed to the lower sill 12 of the first window 5, and slides down along the inclined surface 30A, and the lower end of the grooved cam 29 slides down to the stopper portion 30B and comes to a stop. .

Therefore, while the second window 7 is moving, it is supported in the vertical direction by the guide groove 18 and the guide pin 20 in the upper part and by the grooved cam 29 and the support plate 30 in the lower part, so that no vibration occurs. do not have.

Further, when the handle is rotated counterclockwise, the actuating plate 38 is pulled upward in the opposite direction to the above, and at the same time, the groove cam 29 is pulled up, so that the second window 7 is moved into the guide groove 18 by its own weight via the guide pin 20. Slide down toward the first window 5. This movement causes the rotation pin 40A of the cam plate 40 to move into the groove 40 of the actuating plate 38.
Enter A′ and the cam plate will fit behind the operating plate. If the above-mentioned lifting movement of the actuating plate 38 is further continued,
This time, the rotation pin 41A of the hook plate 41 is guided by the bent portion 45B of the operating plate 38, and the hook plate 41 projects to the right (FIG. 13) and is latched to the latching pin 43.

The above-mentioned rotational movements of the cam plate 40 and the hook plate 41 are performed alternately, and when the cam plate 40 is projected, it hits the abutment plate 42 attached to the first window 5 in advance, and the first window 5 and the second window 7 are rotated. The gap is opened sufficiently so that the second window 7 is parallel to the first window. Also hook board 41
When it protrudes in a rotational manner, it engages with the latching pin 43 attached to the first window 5 in advance, and the first window 5 and the second window 7
