When the screen door 3a is attached, the locking piece 37 is set in the mounting posture so that the frame 35 can come into contact with the indoor side surface of the screen door mounting portion of the screen door frame 3.
And the latching piece 37 is made into a holding | maintenance attitude | position, and it contacts the outdoor side surface of the above-mentioned screen door attaching part 30a, 31a.

As shown in FIGS. 5 and 6, the lock 5 includes a lock body 50 attached to an intermediate portion in the in-plane direction (longitudinal direction) of the upper frame 10 and an intermediate in the in-plane direction (longitudinal direction) of the upper collar 20. A lock receiver 51 attached to the section is provided.
The lock body 50 has a lock 52, for example, a latch, which is engaged with and disengaged from the lock receiver 51 to lock and unlock.
The lock rod 52 is movable between a locking position for locking to the lock receiver 51 and a releasing position for releasing the lock receiver 51, and is always held at the locking position, and the opening wire 6a described above. To move to the release position.
In addition, when the shoji 2 in the open position is rotated (closed) toward the closed position, the lock shim 52 is moved toward the disengaged position by the lock receiver 51, and the shoji 2 is moved. When in the closed position, the lock rod 52 is locked to the lock receiver 51 and is locked.
For example, the lock rod 52 can be rotated in the interior and exterior direction between a lower locking position and an upper detachment position, and can be moved vertically between a lower locking position and an upper detachment position. The external force that is held in the locking position by the spring and moves toward the outside of the room does not rotate toward the disengagement position, but moves upward toward the disengagement position with an upward external force.
A lock member is provided to hold the lock bar 52 in the lower locking position and lock it so as not to rotate to the upper release position. The lock member is held in the aforementioned lock position by a spring, and the opening wire 6a is provided. When pulled, it moves to the unlocked position, allowing the lock rod 52 to rotate to the disengaged position.
When the lock holder 51 interferes with the lock pad 52, an upward external force acts on the lock pad 52, the lock pad 52 moves to the upper disengagement position against the spring, and the lock pad 52 moves into the hole of the lock pad 51. When it is opposed to, it moves downward by a spring and becomes a locking position.
In FIG. 6, the lock body 50 has a cover 50b, and the cover 50b covers the above-described lock material, spring, and the like.

  Since it is like this, by making the shoji 2 into the closed position with the closing wire 6b as described later, the lock 5 is automatically locked, and the shoji 2 can be held in the closed position.

A wire penetration hole 34 is formed in the wire penetration portion 32 c of the screen door vertical frame 32.
The wire through hole 34 is opposed to the portion of the lock body 50 to which the opening wire 6a is connected, for example, the wire connecting portion 50a connected to the above-described locking material in the in-plane direction, and is substantially in the same position in the out-of-plane direction. In addition, the opening wire 6a connected to the wire connecting portion 50a at substantially the same position in the vertical direction is passed through the wire through hole 34, so that the lock body 50 of the opening wire 6a and the screen door vertically The portion between the frame 32 is directed in the in-plane direction, is substantially parallel to the upper frame 10 in the out-of-plane direction, is substantially horizontal, the wire operating direction is straight, and there are no turning points.

The opening pulley 7a has an attachment portion and a wire winding portion. For example, as shown in FIGS. 5, 7, and 9, a pulley 71 is rotatably attached to a pulley body 70 by a support shaft 72, and the pulley body 70 is shaken in an out-of-plane direction by a support shaft 74. It is mounted movably. The mounting bracket 73 is a mounting portion, and the pulley 71 is a wire winding portion.
As shown in FIG. 4, the mounting bracket 73 is fixed to an indoor side surface of the pulley mounting portion 32 b of the screen door vertical frame 32 by, for example, a fixing tool 85 for fixing the screen door vertical frame 32 to the pulley bracket 8. And attach.

  Thus, the screen door frame mounting portion 8b of the pulley bracket 8 is in contact with the outdoor side surface of the pulley mounting portion 32b of the screen door vertical frame 32, the mounting bracket 73 is in contact with the indoor side surface, and is fixed by the fixing tool 85. Since the screen door vertical frame 32) is mounted so as to be sandwiched between the opening pulley 7a (mounting bracket 73) and the pulley bracket 8 (screen door frame mounting portion 8b), the mounting strength of the screen door frame 3 and the opening pulley 7a is increased. In addition to securing the pulley bracket 8, only the pulley bracket 8 may be used, and parts added for attaching the screen door 3a can be reduced as much as possible.

The upper part of the pulley 71 is substantially the same height as the wire through hole 34, and the pulley 71 is substantially at the same position in the out-of-plane direction as the wire through hole 34.
Then, the opening wire 6a penetrating the wire through hole 34 is wound around the pulley 71 (the wire winding portion of the opening pulley 7a) and hung down to turn the wire operating direction downward.

  Thus, the opening wire 6a between the lock main body 50 and the screen door vertical frame 32 is operated by the opening pulley 7a attached to the indoor side of the screen door vertical frame 32 without any turning point in the operation direction. Since the direction is turned downward, the opening wire 6a can be provided on the indoor side of the screen door frame 3 by using one pulley. For example, it can hang down.

An opening operation knob 60 is connected to the lower end of the opening wire 6a.
The operation knob 60 is provided with characters “open” and “pull” so that the user can detect that the shoji 2 is opened by pulling the operation knob 60.
The support shaft 72 goes in the out-of-plane direction and is horizontal, and the pulley 71 rotates along the in-plane direction.
The support shaft 74 is directed in the in-plane direction, is horizontal, and swings in the vertical direction.

Thus, by holding and pulling down the opening operation knob 60 by hand, the opening wire 6a moves downward to move the lock rod 52 of the lock body 50 to the release position, and the lock 5 is unlocked. Therefore, the shoji 2 is rotated by the biasing means 4 toward the open position.
Moreover, the wire connecting portion 50a, the wire through hole 34, and the pulley 71 of the lock body 50 are substantially in the same position in the out-of-plane direction, and the opening wire 6a between the wire connecting portion 50a and the pulley 71 is in the in-plane direction. As it goes and is almost parallel to the upper frame 10 in the out-of-plane direction and is horizontal, the opening wire 6a can be smoothly moved only by being wound around one pulley 7a.

There is no problem if the user moves the opening operation knob 60 straight downward, but the operation knob 60 may move downward while moving the operation knob 60 indoors.
In this case, the opening wire 6a hanging from the pulley 71 is inclined toward the indoor side with respect to the vertical, so that the pulley 71 and the pulley main body 70 together with the pulley main body 70 are attached to the mounting bracket as shown by the phantom line in FIG. It swings toward the indoor side in the out-of-plane direction with respect to 73.
As a result, the opening wire 6a does not come off the pulley 71.

  In addition, since the wire through hole 34 formed in the wire through portion 32c of the screen door vertical frame 32 has an arc shape centering on the swing center (support shaft 74) of the pulley 71, the pulley 71 swings as described above. When moved, the opening wire 6 a wound around the pulley 71 does not interfere with the wire through hole 34.

An elastically deformable cover such as a soft resin cover may be attached to the wire through hole 34 and closed, and the cover may be elastically deformed by the movement of the opening wire 6a.
In this way, insects and the like can be prevented from entering from the wire through hole 34.

As shown in FIGS. 5, 6, 8, and 9, the closing wire 6 b is connected to the upper part of the in-plane intermediate portion of the shoji 2, for example, the downward piece 51 a of the lock receiver 51. Then, the closing wire 6b is wound around a pulley 61 attached to the intermediate portion in the in-plane direction of the upper frame 10 to turn the operating direction from the out-of-plane direction to the in-plane direction.
In FIGS. 5 and 6, since the pulley 61 is attached to the lock body 50 with the bracket 62, the closing wire 6b extending in the in-plane direction is positioned below the opening wire 6a extending in the in-plane direction.
Thereby, the wire through-hole 34 formed in the wire penetration part 32c of the left and right other screen door vertical frame 32 is located below the wire through-hole 34 formed in the left and right one screen door vertical frame 32.

The closing pulley 7b is the same as the opening pulley 7a, and is fixedly attached to the pulley mounting portion 32b of the left and right screen door vertical frame 32 together with the pulley bracket 8 by the fixing tool 85 in the same manner as described above.
This closing pulley 7b is located below the aforementioned opening pulley 7a.

The closing wire 6b penetrates the room through a wire through hole 34 formed in the other left and right screen door vertical frame 32, and is provided on the indoor side through a closing pulley 7b (pulley 71). For example, it hangs down.
A closing operation knob 63 is connected to the lower end portion of the closing wire 6b.
The operation knob 63 is provided with characters “Tip” and “pull” so that the user can detect that the shoji 2 is closed by pulling the operation knob 60.

  Therefore, the shoji at the open position can be rotated toward the closed position by holding the operation knob 63 by hand and pulling it diagonally toward the indoor side.

In the above embodiment, the screen door frame 3 is attached to the sash frame 1 using the brackets (the pulley bracket 8 and the screen door bracket 9), but the screen door frame 3 is directly fixed and attached to the sash frame 1 without using the bracket. You may do it.
For example, the outdoor portion 32a of the screen door vertical frame 32 is fixedly attached to the indoor side mounting piece 12b of the vertical frame 12 with a fixing tool. In this case, it is preferable to provide a spacer between the indoor side mounting piece 12b and the outdoor side portion 32a.
Although the screen door frame 3 can be retrofitted to the sash frame 1, the sash frame 1 may be attached to the building frame with the screen door frame 3 attached to the sash frame 1.
In addition, it is not limited to a fallen window, and when the shoji is opened like an open window, the shoji protrudes to the outside of the sash frame, and the screen door attached to the indoor side of the sash frame does not interfere with the shoji. Such a sash window may be used.
