DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, the foldable screen device of the present invention is mounted on one of the left and right halves of a building opening, such as a window or an entrance, so that it can be moved left and right along a rail. 1 to 3, reference numeral 1 denotes a rectangular screen, and 2 denotes an insect repellent mounted in the screen frame 1 so as to be openable and closable in a laterally open manner by expansion and contraction in the left-right direction. The screens 2 and 3 also indicate the shutter curtain 3 which is attached so as to be openable and closable by expansion and contraction, and has a heat insulating property and / or a light shielding property.

The screen frame 1 is a groove-shaped upper frame member 1.
a and the lower frame member 1b and the left and right side frame members 1c and 1d,
The rolling wheel 5 assembled by being connected to each other with screws and attached to the lower frame member 1b, and the attachment member 6 attached to the upper frame member 1a so as to be vertically adjustable,
It is mounted so as to be movable along the rails 7a and 7b in the building opening.

The insect screen 2 is constructed such that a large number of pleats 2a are applied to a flat sheet in a zigzag manner so that the insect screen can be extended and contracted in an accordion manner. A plurality of tubular pieces 9 which can be folded flat by providing pleats 9a are sequentially joined at a joining portion 9b of a required width, so that a large number of elastically stretchable tubular portions 3a are continuously formed. The insect screen 2 and the screen 3 are provided on the left and right sides of the screen frame 1 with the pleats in the vertical direction and the upper and lower ends of the recesses of the upper frame member 1a and the lower frame member 1b. 10a,
It is arranged so that it may be expanded and contracted in the left-right direction by fitting into each of the members 10b. The outer end of the insect net 2 is fixed in the concave portion 11a of the one side frame member 1c by the locking plate 2b, and the outer end of the curtain 3 is engaged in the concave portion 11b of the other side frame member 1d. Fixed by the stop plate 3b,
Opposite inner ends of the insect screen 2 and the screen 3 are attached to both sides of a common movable frame 13 for opening and closing operation by locking plates 2b and 3b, respectively. By moving to the side, the insect screen 2 and the screen 3 can be selectively opened and closed to be used properly.

As the insect repelling net 2, a net made of a filament made of chemical fiber or other appropriate thin wire is preferably used.
As the shutter 3, a sheet material having desired heat insulating properties and light shielding properties, such as woven or nonwoven fabric, paper, or synthetic resin sheet, is suitably used.

The movable frame 13 has a pair of wheels 14 at its lower end, and the wheels 14 run on the rails 15 of the lower frame member 1b. In order to stabilize the running, at the upper and lower ends of the movable frame 13,
Guide members 16a and 16b are provided in a protruding manner, respectively, and these guide members 16a and 16b are formed in guide grooves 17 formed in the upper frame member 1a and the lower frame member 1b of the screen frame 1.
a and 17b are slidably fitted.

The mounting surfaces of the movable frame 13 on which the insect screen 2 and the screen curtain 3 are mounted are respectively formed with recesses 13a and 13b, and the recesses 13a and 13b of the movable frame 13 and the recesses of the side frame members 1c and 1d. 11a, 11b and insect repellent net 2
When the movable frame 13 is moved to either the left or right side and one of the insect screen 2 or the screen 3 is folded, the insect screen 2 folded inside the accommodation section is formed. Alternatively, the shutter 3 is completely stored. At this time, the movable frame 13 is provided with the concave portions 11 of the side frame members 1c and 1d.
a, 11b may be brought into contact with the inner bottom.

When the movable frame 13 is moved, the movable frame 13 is prevented from tilting in the moving direction, thereby preventing the operation from becoming unsmooth. By holding the movable frame 13 vertically, the upper and lower ends thereof can be reliably secured. In order to be able to translate in parallel, there is provided a translation mechanism substantially consisting of two tension cords. The parallel moving mechanism includes a first tension member fixed at both ends to an upper half portion of the movable frame 13 on the insect repellent net 2 side and a lower half portion of the movable curtain 13 and movably stretched into the screen frame 1. The screen frame 1 is fixed at both ends to the string 21, the upper half of the movable curtain 13 on the blocking curtain 3 side, and the lower half of the insect screen 2.
And a second tension string 22 movably stretched in the upper and lower ends of the movable frame 13 through these tension strings.
It is configured such that forces of the same magnitude act simultaneously in the movement direction.

The parallel moving mechanism will be described in more detail. In FIG. 1, the first tension cord 21 has one end fixed to the upper half of the movable frame 13 and extends leftward in FIG. Through to the left side frame member 1c,
It is wound around the deflecting elements 23 and 24 and guided into the upper frame member 1a, is guided through the inside of the upper frame member 1a to the right side frame member 1d, is wrapped around the upper and lower deflecting elements 25 and 26, and After being reversed in the direction, it is guided to the movable frame 13 through the curtain 3, and the tip is fixed to the lower half of the movable frame 13. On the other hand, the second string 20b is
One end is fixed to the upper half part, extends rightward in the figure, is guided to the right side frame member 1d through the blocking curtain 3, and is then wound around the deflecting elements 27 and 25, and the upper frame member 1a And is guided to the left side frame member 1c through the upper frame member 1a, is wound around the upper and lower divertors 24 and 28, is turned rightward, and is movable through the insect repellent net 2. The movable frame 13 is guided to the frame 13, and its tip is fixed to the lower half of the movable frame 13. Reference numeral 28 in FIG.
1 shows one of the screws for fixing the end of the screw.

When the movable frame 13 is moved to the left and right, forces of the same magnitude are simultaneously applied to the upper and lower halves of the movable frame 13 through the tension cords 21 and 22 in the moving direction. The movable frame 13 horizontally moves at both upper and lower ends while reliably maintaining the vertical position.

In addition, when movable frames are separately mounted on the insect screen 2 and the curtain 3, respectively, it is necessary to install two tension cords on one movable frame. Although a total of four tension cords are required, in the above-mentioned screen device, one movable frame 13 is commonly attached to the insect screen 2 and the screen 3, so that only two tension cords 21 and 22 are required. A translation mechanism can be configured.

When the insect screen 2 is used in the summer in the screen device having the above structure, the insect screen 2 is extended by moving the movable frame 13 to a position where the movable frame 13 contacts the side frame member 1d on the right side of the figure. The curtain 3 is folded and stored between the movable frame 13 and the side frame member 1d. Further, when the shutter 3 is used for heat insulation or light shielding in winter or other seasons, the movable shutter 13 is moved to a position where it comes into contact with the side frame member 1c on the left side of the drawing, so that the shutter 3 is extended. The insect net 2 is folded and the movable frame 13 and the side frame member 1c are folded.
Is stored between.

Thus, by simply moving one movable frame 13 to the left and right, the insect screen 2 and the screen 3 can be easily used as needed. Insect screen 2 and screen 3
When the movable frames are separately mounted on the movable frames, not only two movable frames are required, but also the wheels 14 and the guide members 16a and 16b are mounted on both the movable frames in the same manner. Since it is necessary to provide an engaging and disengaging means for connecting the movable frame, the number of members increases, the structure becomes complicated, and even if the width of the two movable frames is made as narrow as possible, the width when they are connected Is inevitably wider than in the case of a single movable frame 13, so the frontage of the screen frame 1 is narrowed accordingly. However, such a problem is solved because the screen device has only one movable frame. . In addition, the screen device can be easily moved to the side where the insect repelling net 2 or the shutter 3 at the right side or the left half of the building opening is to be used by moving the screen device left and right along the rails 7a and 7b. It can be moved out of the way even when entering and exiting through a building opening.

In the above embodiment, the shutter 3 has a structure in which a large number of extendable and contractible tubular portions 3a are provided in a row, but the shutter 3 is shown in FIGS. As described above, a configuration in which the cylindrical portion 3a that can be expanded and contracted by pleats may be formed by laminating two, three, or four or more layers in the thickness direction of the curtain 3 may be used. It goes without saying that the positional relationship between the insect screen 2 and the screen 3 may be reversed left and right with respect to the embodiment.

Further, the folding type screen device may include:
It can be configured to be attached not only to one half of the building opening but also to the entire surface. In this case, the wheel 14
Is not necessary, and the screen frame 1 is attached to a building opening frame such as a sash by appropriate fixing means such as screwing or bonding.

[0020]

As described in detail above, according to the present invention,
The screen can be opened and closed freely to expand and contract horizontally.
Screen device with many pleats
Insect-repellent insect net with accordion style and telescopic
Insulation or light shielding for connecting the cylindrical parts of
The curtain and the curtain can be effectively used properly. As a result, it is possible to eliminate the waste that the screen door and the shutter, which are different products, are double attached to the opening of the building. Also, since it is only necessary to provide one movable frame, compared to the case where two movable frames of the same configuration are separately mounted on the insect screen and the screen curtain, the number of members used is reduced and the structure is simplified. In addition, the width occupied by the movable frame in the screen frame can be reduced, and the frontage of the screen frame can be widely used.
