[0012]

However, the wire tension mechanism 20 in the above-mentioned middle opening assembly screen door device of the invention of the prior application is composed of the first and second movable members 11, 1.
In order to prevent the rocking of 2 and make it self-supporting,
For example, not only a jig such as a stopper is required to fix C on the way of the wire 21 that is bridged between the fifth guide roller 26 and the sixth guide roller 27 after the tensioning of the wire 1 has been completed. The fixing C by this 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 is 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. And tension adjustment work is troublesome.

Further, such an assembled screen door device main body 10
When attaching the sash frame 1 to the sash frame 1, the wire tension mechanism 2
Since the first and second fixing members 14 and 15 to which the wire 21 of No. 0 is suspended and fixed are used, there is a problem that the number of components of the assembled screen door apparatus main body 10 is large and the cost is high.

[0015]

It is an object of the present invention to eliminate the above problems, simplify the tension adjustment of the wire tension mechanism and the wiring work, and improve the workability and reduce the cost. It is to provide an assembly screen door device.

[0016]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to an upper and lower frame which is assembled and fixed to both upper and lower frames between left and right vertical frames forming an opening such as a window of a building. The first guide rail and the first and second guide rails that are horizontally movably assembled in an upright state between the upper and lower guide rails.
And a second movable member, and pleats that are provided between the first movable member and the second movable member and that can be folded and expanded to open and close freely by following the opening and closing movements of the movable members. And a mesh member having a shape of a mesh, which is a vertically-opened assembled mesh door device, and is vertically crossed so as to prevent the first movable member from swinging in the opening / closing movement direction and to be self-supporting. A first wire tensioning mechanism composed of at least two wires to be passed over and up and down so as to be independent of the first wire tensioning mechanism and prevent the second movable member from swinging in the opening / closing movement direction to be self-supporting. A second wire tensioning mechanism composed of at least two wires that are crossed over and crossed over
Also, each of the wires constituting the second wire tension mechanism has a structure in which both ends thereof are fixed and hung over the upper guide rail and the lower guide rail, respectively.

[0017]

That is, according to the present invention, by adopting the above-mentioned structure, the first and second movable members constituting the assembled screen door body are prevented from swinging in the opening / closing movement direction so as to be hung independently. Since the passed wire tension mechanism is composed of the first wire tension mechanism and the second wire tension mechanism which are independent of each other, the length of each wire is short, the handling is easy, and the cutting dimension accuracy is high. Therefore, it is not necessary to adjust the dimensional accuracy in the field as in the past, and thus the tension of the wire and the wiring work can be simplified.

Further, both ends of each wire constituting the first and second wire tensioning mechanisms are fixed and hung over an upper guide rail and a lower guide rail which are assembled to both upper and lower frames of the sash frame. Therefore, the number of constituent parts of the main assembly of the assembling screen door device is reduced, which leads to cost reduction.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawing shown in FIG. In the illustrated embodiment according to the present invention, the same parts as those of the assembled screen door device of the prior invention shown in FIGS. 2 to 4 will be described with the same reference numerals.

With the second wire tension mechanism, the first and second wire tension mechanisms 40, 50
Is configured to make the first and second movable members 11 and 12 stand independently of each other.

That is, the first wire tension mechanism 40 includes a first wire 41 and a second wire 42.
This first wire 41 has one end 41a fixed to the left end 6a of the upper guide rail 6 by A, and
The other end 41b is connected to the upper end 11 of the first movable member 11.
It is extended to the side a and is passed from the upper end portion 11a of the first movable member 11 to the lower end portion 11b side through the first guide roller 61, and the lower guide rail is passed through the second guide roller 62. Fix B to the right end portion 7b of 7.

The second wire 42 has one end 42a fixed to the left end 7a of the lower guide rail 7 and has the other end 42b fixed to the first movable member 11.
Of the third guide roller 6 by extending to the lower end 11b side of the
The upper end portion 11a side of the first movable member 11 is folded back over the first movable member 11 so as to intersect with the first wire 41, and the right end of the upper guide rail 6 is passed through the fourth guide roller 64. It is fixed to the portion 6b.

On the other hand, the second wire tension mechanism 50 is composed of a third wire 51 and a fourth wire 52. One end 51a of the third wire 51 has a left end portion of the upper guide rail 6. Fixed to 6a E, and
The other end 52b is connected to the upper end portion 12 of the second movable member 12.
The lower guide is extended to the side a, and is extended from the upper end 12a of the second movable member 12 to the lower end 12b through the fifth guide roller 65 and the lower guide through the sixth guide roller 66. Fix F to the right end 7b of the rail 7.

The fourth wire 52 has one end 52a fixed to the left end 7a of the lower guide rail 7 and the other end 52b fixed to the second movable member 12.
