Claims (7)

[Claims] 1. A screen door provided with a wire tension mechanism for movably raising a movable member between upper and lower frames of an opening of a building, and a pleated mesh member which is expandable and contractable as the movable member moves. In the device, loops are formed on the first row wire and the second row wire at predetermined wiring positions where wires that apply tension to the movable member are arranged in two rows, and each loop is A wire tension adjusting mechanism for a screen door device, which is provided with a tension adjusting means for expanding or contracting at the same time. 2. The wire tension mechanism comprises two wires, one end of which is fixed near the upper end of one side of the opening and the other end of which is from the upper end to the lower end of the movable member. Through, extending toward the other side of the opening, and fixed near the lower end of the other side, while the second wire fixes one end thereof near the lower end of one side of the opening, The other end is passed from the lower end to the upper end of the movable member, extends toward the other side of the opening, is fixed near the upper end of the other side, and is wired in two rows in the upper and lower ends of the movable member. The wire tension of the screen door device according to claim 1, wherein a loop is formed in each of the wires in the first row and the wire in the second row, and tension adjusting means for simultaneously expanding or contracting the loops in each row is provided. Adjustment mechanism. 3. The wire tension mechanism is composed of one wire, one end of the wire is fixed to an upper part of the movable member, and the other end is fixed to a lower part of the movable member, and each of them is fixed. In the interval, the wire extends from the upper part of the movable member toward the first vertical frame provided on one side of the opening, and is passed from the upper part to the lower part of the first vertical frame, and the lower part thereof. The second part which is folded back toward the other side of the opening and is provided on the other side
Is folded back toward the lower part of the movable member at the lower part of the vertical frame, extends from the lower part of the movable member toward the upper part, and reaches an intermediate fixed point, and from the upper part of the movable member from the intermediate fixed point. It is extended toward the second vertical frame, folded back toward the first vertical frame at the upper part of the second vertical frame, and passed from the upper part to the lower part of the first vertical frame, The first row of wires and the second row of wires, which are folded back toward the lower part of the movable member at the lower part, are wired so as to reach the lower part of the movable member, and are wired in the upper and lower end directions of the first vertical frame. 2. A wire tension adjusting mechanism for a screen door device according to claim 1, further comprising a tension adjusting means for forming a loop on each of the wires and expanding or contracting the loops of each row at the same time. 4. The wire tension mechanism comprises two wires, one end of which is fixed to an upper portion of the movable member and the other end of which extends toward one side of the opening. , And to pass it along the upper guide member provided at the upper part of the opening by reversing from the upper part of one side,
While extending to the upper part of the other side part of the opening part, the other end of this extension extends from the upper part of the other side part of the opening part to the lower part so as to follow the lower guide member provided at the lower part of the opening part. Through and fixed by folding back toward the lower part of the movable member,
On the other hand, one end of the second wire is fixed to a lower portion of the movable member, the other end thereof extends toward one side portion of the opening portion, and the second wire is inverted from a lower portion of the one side portion so that the lower guide is formed. While extending along the member to the lower portion of the other side portion of the opening, the other end of the extension extends from the lower portion of the other side portion of the opening through the upper portion so as to follow the upper guide member. The first guide wire and the second wire wired in two rows in the left-right direction of the lower guide member are looped through and fixed to the upper part of the movable member through the loops at the same time. The wire tension adjusting mechanism for a screen door device according to claim 1, further comprising a tension adjusting means for expanding or contracting. 5. The tension adjusting means includes a movable member, an upper frame,
Any one of a lower frame, a right vertical frame as the first vertical frame, a left vertical frame as the second vertical frame, an upper guide member, a lower guide member, and a fixing member attached to each of the left and right vertical frames. It is provided, The wire tension adjusting mechanism of the screen door apparatus of Claim 1 characterized by the above-mentioned. 6. The tension adjusting means includes a first engaging portion and a second engaging portion that engage with each loop, and each engaging portion is arranged along a wire wiring. The wire tension adjusting mechanism for the screen door device according to any one of claims 1 to 4, wherein the wire tension adjusting mechanism is configured to be movable in the wiring direction. 7. A wire tension adjusting method for adjusting the wire tension of a wire tension mechanism using the wire tension adjusting mechanism according to claim 1, wherein the tension adjusting means is used to simultaneously expand the loops in each row. Then, the tension of the wire is increased, while the tension adjusting means is used to simultaneously reduce the loops in each row to reduce the tension of the wire.
