Next, the mesh section 70 will be described. As shown in FIG. 5, the net portion 70 has a height as an inner dimension of the frame 1 so that the opening in the frame formed in the frame 1 can be completely closed with the shoji 3 open. It is formed slightly wider in the vertical and horizontal directions than the height H and the width W. This net portion 70 may be made of polyester or a rollable gold material.
Instead of a so-called "net" shape, it may be made of finer cloth, shoji paper, etc., and its function may be light shielding in addition to ventilation, and any pattern or color may be added. May be. That is, any screen as a sheet-shaped member may be used. The present device can function not only as a screen door but also as a curtain, a blindfold, a shoji door, a partition, or the like for various purposes such as ventilation and shading.

As shown in FIG. 6, a vertically long plate-shaped fixing portion 71 fixed to the vertical frame 13 of the frame 1 is attached to an end of the net portion 70 on the drawing side by bonding. FIG. 11 is an enlarged cross-sectional view of a main part of the fixing portion 71 and the vertical frame 13, and FIG.
Shows a state in the middle of fixing, and (b) shows a state after the fixing. As shown in FIG. 11, a locking portion 17 having a substantially U-shaped cross section is provided in the vertical frame 13 so as to be opened inward in the direction in which the mesh portion 70 is locked. The nail 17a
Is formed in a groove shape, and the other claw 17 b is
It is shaped so as to oppose a length that is not deviated from the locking portion 17 by being pushed by the boss. The fixing portion 71 is inserted into the locking portion 17 in a tilted state (FIG. 11A), and is arranged parallel to the expected direction (FIG. 11B).
, The fixing portion 71 can be locked.

The locked state can be easily released by the reverse operation. If the projection 71a is provided continuously or partially on the exposed surface of the fixing portion 71, the lock release becomes easy.
In this manner, the end on the drawing side of the net portion 70 can be fixed to the vertical frame 13 via the fixing portion 71, so that the storage case 4
By sliding the “0”, the net portion 70 can be automatically pulled out from the storage case 40. Further, since the fixing portion 71 is detachable from the locking portion 17 as described above, the net portion 70 can be easily removed from the vertical frame 13 when cleaning or unnecessary. The locking portion 17 may be formed integrally with the vertical frame 13. However, if the locking portion 17 is formed separately and can be attached by bonding or screwing, it can be attached to an existing window sash. If cleaning or the like is not considered, the fixing portion 71
May be completely fixed to the vertical frame 13.

The upper and lower ends of the net portion 70 correspond to the upper and lower frames 1.
The first and second rising walls are provided so as to be able to adhere to the fastener portions 18 provided on the rising walls. Here, the rising wall is adjacent to the net portion 70 and is provided for both the rails 15 and 16 or protruding in accordance with the net drawing position. In the present embodiment, the rising wall is provided for both the rails 15 and 16. As shown in FIGS. 1 to 3, the fastener portion 18 is formed over the entire length of the side surface on the net portion 70 side of the rails 15 and 16 as rising walls, and is directed toward the net portion 70 side. The protruding needle-like projections are provided continuously at regular intervals. Here, the net portion 70 is fixed with the fixing portion 71 along the rails 15 and 16 as shown in FIG.
Further, as described later, a support shaft 72 for winding the net portion 70 is urged toward the opening 45 of the storage case 40, and the opening 45 is formed near the rails 15 and 16, as shown in FIG. I have. Therefore, the net portion 70 pulled out from the opening 45 is automatically arranged along the rails 15 and 16, and the projection of the fastener portion 18 is locked in the net.

Further, since the mesh portion 70 is urged by a winding portion 80 described later in a winding direction (a direction toward the storage case), tension is always applied to the mesh portion 70, and The locked state between the projection 70 and the projection of the fastener portion 18 is stably maintained. Since the upper and lower ends of the mesh portion 70 are in close contact with the fastener portions 18 of the upper and lower frames 11 and 12 in this manner, a gap is prevented from being formed between the mesh portion 70 and the upper and lower frames 11 and 12, and the wind is reduced by the wind. It is possible to prevent the 70 from inadvertently floating in the viewing direction and prevent insects from entering from gaps. The fastener 18 can be attached to the upper and lower frames 11 and 12 by bonding or screwing, and can be easily attached to an existing window sash. Further, it is also possible to add a fastener mounting rail by increasing the edge and mount the fastener portion 18. When the net portion 70 is made of a cloth material other than the net, the fastener portion 18 is not necessary. As shown in FIG. 7, a hollow support shaft 72 is fixed to the end of the mesh portion 70 on the storage case 40 side.

Next, the winding section 80 will be described. FIG. 12A is an enlarged view of the winding section 80, and FIG.
(B) shows each. As shown in FIG. 12, the winding unit 80 includes a winding spring 81 serving as a vertically long urging member, a mandrel 82 of the winding spring 81, and a shaft-side fixing unit that fixes the winding spring 81 to the support shaft 72 of the mesh unit 70. A tool 83, a case-side fixture 84 for fixing the winding spring 81 to the storage case 40, and a guide member 85 for guiding the rotation of the winding spring 81 are provided. The helical spring 81 is formed to have a diameter and a length that can be inserted into the support shaft 72 of the mesh portion 70, and is prevented from being carelessly bent by inserting the mandrel 82 therein.

A shaft-side fixing member 83 is fixed to the lower end of the winding spring 81. That is, the shaft-side fixing member 83 is
3a and a short shaft 83b having a thread groove protruding from the upper end of the main body 83a. The short shaft 83b is inserted into the coil spring 81 so that the coil spring 81 is locked in the screw groove. And is fixed so that it cannot rotate. FIG.
As shown in (1), by inserting the shaft-side fixing member 83 into the support shaft 72, the shaft-side fixing member 83 is non-rotatably fixed in the support shaft 72. That is, as shown in the cross-sectional view of the support shaft 72 in FIG. 13, a plurality of grooves 72 a are formed on the inner periphery of the support shaft 72, while the grooves of the support shaft 72 are formed on the side surface of the shaft-side fixture 83. A plurality of projections 83c corresponding to 72a
Is formed and the projection 83c is accommodated in the groove 72a, so that the shaft-side fixture 83 cannot be rotated. Therefore, the lower end of the winding spring 81 is fixed to the support shaft 72 so as not to rotate via the shaft-side fixing member 83.

On the other hand, a case-side fixture 84 is fixed to the upper end of the coil spring 81. The case-side fixing member 84 is composed of a main body portion 84a and a short shaft 84b having a screw groove. By inserting the short shaft 84b into the winding spring 81, the winding spring 81 is non-rotatably fixed. FIG.
2 shows a plan view of the storage case 40 in which the winding unit 80 is stored. As shown in FIG. 14, the case-side fixture 8
4 has an outer shape substantially adapted to the inner diameter of the storage case 40.
When the main body 84a is stored in the storage case 40,
And is non-rotatably fixed to the storage case 40. Therefore, the winding spring 81 is connected to the case-side fixture 8.
The upper end is fixed to the storage case 40 so as to be non-rotatable via 4. The guide member 85 allows the short shaft 84b of the case-side fixture 84 to pass therethrough and is interposed between the main body 84a of the case-side fixture 84 and the winding spring 81 to guide the rotation of the winding spring 81. .

From these facts, the winding spring 81 is fixed to the supporting case 72 at the lower end thereof, and is fixed to the storage case 40 at the upper end thereof in a state of being biased in a suitable amount in the winding direction in advance. As the part 70 is pulled out, the winding spring 81 is further twisted, and the urging force increases in the direction in which the net part 70 is wound into the storage case 40. It should be noted that the strength of this urging force is such that the storage case 40 is locked to the vertical frame 33 of the shoji 3 as shown in FIG. In such a state, the strength is determined so that the net portion 70 can be automatically wound.

As shown in FIG. 14, an elongated hole 84c is formed in the main body 84a of the case-side fixture 84 from the substantially center position of the plane of the storage case 40 toward the opening 45. The short shaft 84 of the case-side fixture 84
b, and a pressing spring 84d are provided. The upper end of the short shaft 84b is movable within the long hole 84c along the long hole 84c, and the pressing spring 8
At 4d, it is constantly urged toward the opening 45 side and cannot rotate. Therefore, the mesh portion 70 is constantly urged toward the opening 45 side of the storage case 40 via the case-side fixing member 84, the winding spring 81, and the support shaft 72 in this order, so that the mesh portion 7
0 can be pulled out along the opening 45 side, that is, along the rails 15 and 16 sides of the upper and lower frames 11 and 12.

Next, a method of attaching the sash window screen doors 4 and 5 will be described. First, the net part 70 and the winding part 80 are stored in the storage case 40, and the upper cap 50 and the lower cap 60 are attached to assemble the main screen doors 4, 5. After the frame 1 is framed in a rectangular shape, especially when the frame 1 is mounted on an existing sliding window, the upper and lower frames 1 are mounted beforehand or before the screen doors 4 and 5 are mounted.
Attach fastener parts 18 to 1 and 12. Then, the assembled screen doors 4 and 5 are inserted into the frame 1 in a state where the screen doors 4 and 5 are tilted in the direction of finding, and are vertically built up to be built in the frame 1. Installation is completed only by locking. According to such a method, it is possible to easily attach the sliding doors to the existing sliding window without removing the sliding doors 2 and 3. When the screen doors 4 and 5 are not used for a long time, the screen doors 4 and 5 can be easily removed from the frame 1 and stored in a warehouse or the like by the reverse procedure.

Alternatively, in the case of attaching to a newly-installed window sash, a frame using one of the upper and lower frames 11, 12 and the left and right vertical frames 13, 14 in parallel with the assembly of the main screen doors 4, 5. 1, the main screen doors 4, 5 and the sliding doors 2, 3 are housed in the frame body 1 from the open side, and the other one of the left and right vertical frames 13, 14 is attached to the frame body 1, May be framed in a square. Also, as described in a second embodiment to be described later, the main screen doors 4 and 5 may be stored in a state where the frame 1 is formed in a U-shape. In addition, as shown in FIG. 1, when the mounting height of the shoji 2 and the shoji 3 is different, and the screen door 4 and the screen door 5 are set to different heights, either the upper or lower end of the storage case 40 and the screen 70 is optional. It can be handled by cutting only the length.

Next, a method of operating the main doors 4 and 5 will be described. First, as shown in FIG. 2, in a state where both the shojis 2 and 3 are closed, the main screen doors 4 and 5 are arranged adjacent to the side of the vertical frames 13 and 14. In this state, the storage case 40
Is arranged at a position overlapping with the vertical frames 23 and 33 of the sliding doors 2 and 3 in the expected direction, and the storage case 40 is formed narrower than the vertical frames 23 and 33 as described above.
Moreover, since it is made of the same material as the vertical frames 23 and 33, the storage case 40 is also similar to the vertical frames 23 and 33 when viewed from the indoor side as shown in FIG. It is inconspicuous as one, and is also good in design.

When the screen door 4 is used in such a state, the shoji 3 is first opened to an arbitrary place. FIG. 3 shows a state in which the shoji 3 is fully opened. Then, the storage case 40 of the screen door 4 is moved through the handle 46 to the vertical frame 33 of the shoji 3.
The vehicle travels horizontally to a position where it overlaps in the expected direction. Prior to this, since the fixing portion 71 of the net portion 70 of the screen door 4 is locked by the locking portion 17 of the vertical frame 13, the net portion 70 is automatically released from the storage case 40 as the storage case 40 travels. The upper and lower ends of the net portion 70 are fixed to the fastener portions 18 of the upper and lower frames 11 and 12 at the same time as being pulled out. Then, at the overlapping position of the storage case 40 and the vertical frame 33,
The locking projection 41b of the storage case 40 is locked to the locking projection 33b of the vertical frame 33, and the storage case 40 is fixed to the shoji 3 or the frame 1. Thereby, the opening in the frame generated by opening the shoji 3 is closed by the net portion 70 as shown in FIGS. In this state, in the present embodiment, the storage case 40 is slid instead of the net portion 70 side with the movement of the shoji, and therefore, as shown in FIG. Since it is arranged at a position overlapping with the third vertical frame 33 in the viewing direction, it is possible to maintain good design.

When closing the screen door 4 by closing the shoji screen 3, first, the locking between the locking projection 41 b of the storage case 40 and the locking projection 33 b of the vertical frame 33 is released via the handle 46.
When the hand holding the storage case 40 is released, the mesh portion 70 is automatically urged in the winding direction.
The vehicle travels while winding the net portion 70 toward 3, and reaches a position adjacent to the vertical frame 13. Since the storage of the net portion 70 is completed, the shoji 3 can be closed, and the state shown in FIGS.
