Then, from the closed state, if you hold either the upper shoji 1 or the lower shoji 2 in your hand and move it downward or upward as indicated by E, the other lower shoji 2 or upper shoji 1 will move to the direction indicated by the arrow E.
, D, a rotor 5 such as a gear rotatably pivoted at substantially the center in the vertical direction of the left and right vertical frames 3, 3 so as to open and close in an interlocking manner upward or downward, and a rotor 5 such as a gear in the opposite direction to the rotor 5. The upper shoji 1 and the lower shoji 2 are each provided with rack-shaped linear engagement portions 6.6 for interlocking with each other. Furthermore, the vertical frame 3 includes a fixed frame portion 7 and a guide frame portion 8.
The guide frame part 8 is swingably fixed to the fixed frame part 7 by means of a pivot member 9 and removable fixtures 10. Once removed, the lower shoji 2 can be swung toward the indoor side R using the pivot 9 as a fulcrum, as shown by the imaginary line in FIG. 1, while holding the lower shoji 2.

To explain more specifically with reference to FIGS. 3, 4, and 5, the fixing frame 7 has a substantially T-shaped cross section, and is fixed to the building opening 13 with fixing devices 11 and 12 such as screws and nails. The rotor 5 is attached to the fixed frame portion 7 via the attachment plate 14. That is, the rotor 5 has a support shaft 1 erected on the mounting plate 14.

・It is removably attached to the fixed frame part 7. Furthermore, two protrusions 17.18 in the vertical direction are provided in parallel with each other at a predetermined interval on the center wall part 7a of the fixed frame part 7, and the cross-sectional shape is approximately T-shaped between the two protrusions 17.18. The above-mentioned guide frame portion 8 of the shape is attached as a fitting. A locking hole 19 consisting of a large diameter portion 19a and a small diameter portion 19b is provided in the vicinity of the lower end of the guide frame portion 8, and a pivot hole 19 consisting of a stepped screw or the like that can be fitted into and engaged with the locking hole 19 is provided. A tool 9 is provided protruding from the fixed frame portion 7 side. The head 9a of the pivot tool 9 is connected to the above-mentioned latching hole 19.
The shaft portion 9b can be inserted into the large diameter portion 19a of the large diameter portion 1.
It can be fitted into the small diameter portion 19b from 9a. Further, the length of the shaft portion 9b is made approximately equal to the height of the protrusions 17, 18 plus the plate thickness of the guide frame portion 8, so that the guide frame portion 8 is It becomes possible to move away from the angle of 17°18, and it becomes possible to swing toward the indoor side R using the pivot 9 as a fulcrum as shown by the imaginary line in FIG. In a normal state, the guide frame section 8 is fixedly attached to the fixed frame section 7 by the above-mentioned fixture 10. Specifically, a screw is used as the fixture 10, and the guide frame 8 is connected to the fixture 10.
... is tightened to the fixed frame portion 7 at multiple locations. Further, an arcuate portion 8a is formed at the lower end of the guide frame portion 8 to avoid interference with the lower frame 20 of the window frame 4 during swinging, and a circular arc portion 8a is formed at the lower end of the guide frame portion 8 to abut against the guide wall portion 7b of the fixed frame portion 7. A chamfered portion 8b is formed to regulate the amount of rocking to a predetermined amount, and a cutout 8C for escape of the rotor 5 and its mounting plate 14 is opened to the outdoor side Q at approximately the middle portion in the vertical direction. It is provided.

Thus, the upper shoji 1 is held vertically movably between the guide wall 7b of the fixed frame 7 and the guide frame 8, and the lower shoji 2 is held vertically movably within the U-shaped guide portion of the guide frame 8. be done. In this state, the linear engagement part 6 of the upper shoji 1 engages with the rotor 5 from the outdoor side Q, and the linear engagement part 6 of the lower shoji 2 engages from the indoor side R. As shown in FIGS. 6 and 7, the linear meshing portions 6 are integrally punched out from a metal extruded phasing member IA, 2A by press working, and there is a rotor between each tooth portion 6a. The uneven tooth 5a of No. 5 has a rectangular shape into which it can be fitted, and the tooth surface 5b of the uneven tooth 5a.
The contact surface 6b with the tooth surface 6b is bent and press-formed into an inclined shape that substantially coincides with the tooth surface 5b. Furthermore, phasing I
A, the edge of 2A is a bent edge 21, and a linear engagement part 6
reinforcement is being planned. The linear interlocking portion 6 formed in this manner is the left and right vertical stile IA for both the upper and lower shoji 1.2.

IA and 2A, formed over the entire length of 2A. 2
2 indicates a sealing member attached to both the indoor and outdoor surfaces of the NO86 upper and lower shoji 1.2, and 23 in FIG. 2 is a hook swingably attached to the upper frame 24 of the window frame 4. 23 can be hooked onto a pin 26 protruding from the indoor side of the upper stile 25 of the upper shoji 1.

In the above, when the lower shoji 2 is moved upward as shown by the arrow E to open the window, the upper shoji 1, which is interlocked with the lower shoji 2 via the rotor 5, is moved down at the same speed as shown by the arrow. The upper and lower shoji 1.2 are completely overlapped at the middle position between the upper and lower sides of the window, as shown by the imaginary lines in FIG. 2, and are in the maximum open state. Therefore, when wiping the upper and lower shoji 1.2, especially wiping the outdoor side Q of the lower shoji 2, first remove the fixtures 10, which fix the guide frames 8 of the left and right vertical frames 3, 3. At the same time, the pins 26 of the upper shoji 1 are hooked onto the hooks 23 to prevent the lowering of the upper shoji 1, and then the left and right guide frames 8°8 are moved inward and the guide frames 8, 8 are removed. from between the two protrusions 17.18 of the fixed frame portion 7.7. From this state, lower shoji 2
is held by hand, and the guide frames 8, 8 are swung toward the indoor side R using the lower pivot support 9 as a fulcrum, as shown by imaginary lines in FIGS. 1 and 4. This amount of rocking is regulated by the chamfered portion 8b at the lower end of the guide frame portion 8 coming into contact with the guide wall portion 7b of the fixed frame portion 7.

Thereby, the surface of the outdoor side Q of the lower shoji 2 can be easily wiped clean, and the entire upper and lower shoji 1, 2 can be cleaned evenly.

Furthermore, the lower shoji 2 can be removed from the guide frame 8.8 by pulling it upward as shown by the arrow F.Furthermore, the guide frame 8 can be pulled upwards as shown by the arrow F to open the large diameter of the latching hole 19. After the portion 19a is made to correspond to the shaft portion 9b of the pivot 9, it can be removed from the pivot 9 by the large diameter portion 19a. Therefore, the rotor 5 and the upper shoji 1 can be easily removed in order toward the indoor side R, and the window can be assembled, disassembled, and repaired easily and quickly.

Incidentally, the assembly can be carried out in the reverse manner to the above, and in the assembled state shown in FIG. It never occurs.

In addition, when the opposing left and right guide frame parts 8.8 swing toward the indoor side R and are separated from the fixed frame part 7.7, the guide frame part 8
．． 8 may open outward to the sides and the lower shoji 2 may come off, but a structure for preventing such coming off is illustrated in FIG. That is, a hooking piece 27 is provided protruding from the edge of the phasing member 2A where the linear engaging portion 6 of the lower shoji 2 is formed, and an L-shaped protruding piece 28 that engages with the hooking piece 27 is attached to the guide frame portion. This prevents the guide frames 8, 8 from opening in the lateral direction, and effectively prevents the lower shoji 2 from coming off.

Note that by using a stepped screw as the pivot tool 9 and making the locking hole 19 a round hole, the guide frame portion 8 can be attached and removed by attaching and detaching the pivot tool 9.
You may also remove it. Furthermore, the fixing device 10 is not limited to screws, and may have a structure that can be easily attached and detached, such as a bushing/pull type. Furthermore, as a means for preventing the upper shoji 1 from descending, instead of the hook 23, the window frame 4, although not shown, is used.
A hanging hole may be provided through the vertical frames 3, 3, and a pawl may be hooked into the hanging hole, or the lower end of the upper shoji 1 may be in the maximum open position shown by the imaginary line in FIG. It is also possible to use the abutting stopper 29.29 also.

NOl 9 Figures 9 and 10 show another embodiment in place of the two protrusions 17° 18 for positioning the guide frame 8 on the fixed frame 7 side in the above embodiment. Only an L-shaped bent protrusion 29 that forms a groove 30 into which the Q edge fits is provided protruding from the center wall 7a of the fixed frame 7, and the protrusion 29 is fixed as shown in FIG. A predetermined length range of the lower end of the frame portion 7 is left unformed to allow the guide frame portion 8 to swing. Therefore, in this embodiment, there is no need to allow for the amount of axial movement of the guide frame 8 in the shaft 9b of the pivot 9. Also,
The inner surface of the bent piece 29a is a sloped surface so that the bent protrusion 29 is narrower at the inner side of the fitting groove 30, so that the edge of the guide frame 8 can be smoothly inserted into the groove 30. It is arranged so that the positioning can be performed without any hitch.
