In the present embodiment, the grip portion 18 has a cylindrical shape so that it can be easily gripped by a human hand.
Further, in order to fix the slidable first screen door body 11 at an arbitrary position, a fixing screw 19 is provided at a substantially central portion of the lower frame 14. The fixing screw 19 is screwed into fixing means (not shown) inside the lower frame 14, and the first screen door body 11 cannot slide when the fixing screw is tightened.

  The second screen door body 21 is formed by stretching a net portion 25 on a frame body assembled so as to surround four sides by a pair of left and right vertical frames 22 and a pair of upper and lower horizontal frames (upper frame 23 and lower frame 24). It is configured. The net part 25 is fixed to the frame body (vertical frame 22, upper frame 23, and lower frame 24) with an adhesive or the like on its four sides. In the present embodiment, when the temporary screen 1 is installed, the screen 25 is attached to the surface located on the outer side (the balcony side), but is not limited thereto. Further, the upper frame 23 has a shape that does not interfere with the first screen door body 11.

An outer portion (lower portion) of the lower frame 24 is a portion that becomes a lower end face of the temporary screen 1, and the outer portion has a cushioning member 26 such as rubber or cushion sponge having a high friction coefficient that also serves as a slip stopper. Is fixed along the longitudinal direction of the lower frame 24 by an adhesive or the like. The buffer member 26 may be provided on the entire outer portion of the lower frame 24 as in the present embodiment, or may be provided on a part thereof.
In addition, sliding grooves 27 for slidably holding the vertical frame 12 of the first screen door body 11 are formed along the longitudinal direction of the vertical frame 22 in the inner portions of both the left and right vertical frames 22. Yes.

At this time, the width for opening the window 2 is set to be equal to or slightly narrower than the lateral width of the temporary screen door 1. For example, if the width of the temporary screen 1 is 25 cm, the window 2 can be opened to about 25 cm.

After the window 2 is opened and the ventilation area is secured, the position is not overlapped with the moving area of the window 2 on the sash rail 4 so as to cover the ventilation area, and the window 2 moves more than the moving sash rail 4. A temporary screen 1 is installed on the window frame 3 on the indoor side.
Specifically, the height dimension of the temporary screen door 1 is adjusted in accordance with the height of the window 2 (strictly, the height of the window frame 3). When the height of the temporary screen door 1 is adjusted to the height of the window frame 3, the buffer member 26 provided at the lower end portion of the temporary screen door 1 is brought into contact with the lower window frame 3 and the buffer provided at the upper end portion of the temporary screen door 1 is provided. The temporary screen 1 is fixed to the window frame 3 by bringing the member 16 into contact with the upper window frame 3. At this time, since the buffer members 16 and 26 are provided on the upper and lower end surfaces of the temporary screen 1, there is no fear of the window frame 3 being damaged. Moreover, since the buffer members 16 and 26 have a high friction coefficient and also have an anti-slip effect, the temporary screen door 1 can be stably held on the window frame 3.
When installing the temporary screen 1, the height of the temporary screen 1 is slightly lower than the height of the window frame 3, and is temporarily attached to the window frame 3. It is easy to install if adapted.

In the present embodiment, the temporary screen 1 is installed on the window frame 3 on the indoor side of the window 2. Thus, since the temporary screen 1 installed in the window frame 3 does not overlap with the movement area of the window 2 on the sash rail 4, once the temporary screen 1 is installed, the window 2 should be completely closed while being installed. Can be locked. Moreover, when going out (the balcony side), the window 2 should just be opened with the temporary screen 1 installed.
Further, if an auxiliary lock is used, the window 2 can be locked with the ventilation region secured. Furthermore, since the fixing screw 19 that enables expansion and contraction of the temporary screen 1 is located on the indoor side, the temporary screen 1 cannot be contracted and removed from the outside.

  As described above, in the present embodiment, during the repair work of the building such as a large-scale repair work, a part of the window 2 provided in the room is opened to secure a ventilation area, and the temporary screen 1 is installed in the ventilation area. By installing easily, ventilation can be improved and the room can be efficiently ventilated, and invasion of insects and foreign matters from the outside can be suitably prevented. Therefore, the resident can maintain a safe and comfortable living environment even during the construction period.
