Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen door device with a center opening that is installed in an opening frame such as a window of a building such as a general house or an office building.

[0002]

2. Description of the Related Art An assembly screen door device of this type has a construction disclosed in the specification and drawings of Japanese Patent Application No. 4-87526 filed by the present applicant on March 12, 1992. Some have.

In the assembled screen door apparatus of the invention of this earlier application, as shown in FIG. 10, a sash frame 1 as an opening frame of a window of a building, that is, upper and lower frames 2 and 3 and left and right vertical frames 4, The assembled screen door device main body 10 that is assembled to the sash frame 1 frame-formed with 5 includes a pair of first and second left and right fixing members 11 and 12, and the first and second fixing members 11 and 12. A pair of first and second left and right movable members 13, 14 provided between the first and second movable members 13 and 14, and
And a movable member 14 and a foldable and expandable pleated mesh member 15 having an intermediate opening structure.

Then, in order to assemble such a mid-opening assembly screen door device body 10 to the sash frame 1, the left and right vertical frames 4, 5 are assembled.
And the first and second fixing members 11 and 12 are assembled and fixed, respectively, and the first and second fixing members 11 and 12 are fixed.
The first and second movable members 13 and 14 interposed between the upper and lower frames 2 and 3 are movably assembled in the opening / closing direction X along the horizontal direction, and the movable members 13 and 14 are interposed between the first and second movable members 13 and 14. The mesh member 15 can be folded and expanded and contracted in accordance with the opening and closing movement of the mesh member 15.

Further, the inside opening assembly screen door device main body 10
Is provided with a wire tension mechanism 20, and the wire tension mechanism 20 is configured such that the first and second movable members 13 and 14 are self-supported by even tensioning only by tensioning wires, ropes and the like. And a non-stretchable and flexible wire that is stretched between the first and second fixed members 11 and 12 and the first and second movable members 13 and 14. The tension caused by 21 prevents the first and second movable members 13, 14 from swinging when moving in the opening / closing direction X, thereby enabling smooth movement and independent running.

That is, the wire tension mechanism 2
One end 21 a of the wire 21 of 0 has the first fixing member 11
Is fixed to the upper end 11a of the first end of the other end 21b
The movable member 13 is extended to the upper end 13a side.

The other end 21b of the wire 21 extending to the upper end portion 13a of the first movable member 13 has its lower end portion via a first guide roller 22 provided at the upper end portion of the first movable member 13. Fold back to the lower middle part on the 13b side
Is inserted into the lower intermediate portion of the mesh member 15 through the guide roller 23 and extended toward the lower intermediate portion of the second movable member 14, and from the lower intermediate portion of the second movable member 14 to the third guide. The upper end 14 of the roller 24
The second fixed member 12 is folded back up to a and is inserted through the fourth guide roller 25 provided on the upper end portion 14a of the second movable member 14.
To the upper end 12a of the.

As described above, the other end 21b of the wire 21 extending to the upper end 12a of the second fixing member 12 is provided with the fifth guide roller 26 provided on the upper end 12a of the second fixing member 12. Is continuously folded back toward the lower end portion 12b side of the second movable member 14 via the sixth guide roller 27.

[0011]

However, the wire tension mechanism 20 in the assembled screen door apparatus of the above-mentioned prior invention has the self-supporting property by preventing the first and second movable members 13, 14 from swinging. In order to allow the wire 21 to be stretched, a jig such as a stopper for fixing C on the way of the wire 21 stretched between the fifth guide roller 26 and the sixth guide roller 27 is required after the wire 21 is stretched. In addition, the fixing C by the stopper must be released every time the tension of the wire is adjusted.

Moreover, since the wire 21 is one, the total length of the wire to be used becomes long, and the error in the cutting dimension is large, so that it is necessary to adjust the dimensional accuracy on site, which results in the wiring work. There was a problem that the tension adjustment work was troublesome.

[0013]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mid-opening assembly screen door device which simplifies the tension adjustment and wiring work of the wire tension mechanism and improves workability.

[0014]

In order to solve the above-mentioned problems, the present invention is interposed between left and right vertical frames of an opening frame such as a window of a building, and is arranged above and below these left and right vertical frames. A pair of left and right movable members assembled so as to be movable horizontally between the upper and lower frames, and both ends thereof are fixed between the one movable member and the other movable member, and each of these movable members is provided. A pleat-shaped mesh member that is foldable and expandable in accordance with the opening / closing movement, and first and second independent independent members that are hung independently so as to prevent the movable members from swinging in the opening / closing movement direction. And a wire tension mechanism, wherein each of the first and second wire tension mechanisms is composed of at least two wires, and both ends of each of the wires are attached to upper and lower ends of the movable member. With crowded in for folding fixed respectively turning from one in which the movable member of each said set to full open movable into and formed by arrangement in the lateral direction of the opening frame.

[0015]

That is, according to the present invention, by adopting the above-mentioned structure, both ends of each wire of the first and second wire tensioning mechanisms which are independent of each other are provided at the upper and lower ends of the first and second movable members. Since it is turned around from the outside and fixed by folding back, it is not necessary to insert each wire in the movable member in a crossed state as in the past, thereby simplifying the wiring work of the wire And the wire tension can be adjusted easily and easily.
