Description

[Detailed Description of the Invention] The present invention relates to a sash with a screen in which a screen is removably attached to the outside of the window from the shoji on the sash window frame and from the inside of the room.

Conventionally, this type of sash with a screen has a sash screen that is housed on the indoor side of the sash window frame, and the screen door is attached from the outdoor side to the upper and lower screen door rails formed on the outdoor side of the sash window frame.

In other words, grooves are formed in the upper and lower frames of the screen door, and with the upper groove fitted into the upper screen door rail, the screen door is lifted upwards, and the lower end of the screen is positioned above the lower screen rail, and the lower groove becomes the lower screen rail. After matching, the screen door is lowered downward and the lower recessed groove is fitted into the lower screen door rail to attach the screen door to the upper and lower screen door rails.

For this reason, if the screen door is lifted or curved due to strong winds or the like, the screen door may fall off the upper and lower screen door rails toward the outside, which is dangerous.

Furthermore, since the screen door must be lifted upwards, the upper recessed groove fitted into the screen door rail, and then lowered to attach the screen door, it can only be attached and detached from the outdoor side of the satsui window frame.

For this reason, in the case of windows on the second or third floors, attaching and detaching the screen door becomes extremely troublesome.

The present invention was developed in view of the above circumstances, and its purpose is to prevent the screen door from accidentally falling off to the outside due to strong winds, etc. from the satsui window frame, and to
To provide a sash with a screen door which allows the screen door to be easily attached and detached from the indoor side.

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is an overall vertical cross-sectional view of the sash with a screen of the present invention.The sash window frame A is made up of an upper frame 1, a lower frame 2, and vertical frames 3 and 3 on both sides connected together in a rectangular frame, and inside there is an inner and outer sash screen. B ₁ and B ₂ are stored separately, and
A screen door C is installed on the outside of the room.

The board 1a of the upper frame 1 has inner and outer upper rails 4, 5.
is integrally formed downward, and an upper screen door rail 6 in the form of a thin vertical plate is integrally formed downward on the outdoor side of the substrate 1a.

The board 2a of the lower frame 2 has inner and outer lower rails 7, 8.
is integrally formed upward, and a thin vertical plate-like lower screen door rail 9 is integrally formed upward on the outdoor side of the board 2a, and between the lower screen door rail 9 and the outer lower rail 8. A groove 10 is formed in the groove.

That is, the outdoor side portion 2'a of the board 2a from the outer lower rail 8 has a bent piece 11 bent downward and a horizontal piece 1.
2 and a rising piece 13 that becomes a lower screen door rail 9, and the lower screen door rail 9 is integrally formed on the outdoor side of the outer lower rail 8 via a groove 10.

The screen door C has an upper stile 20, a lower stile 30, and vertical stile 4 on both sides.
Screen door body 5 in which 0 and 40 are connected in a rectangular frame
0 has an insect screen 51 stretched over the upper stile 20.
An upper groove 21 opening upward and a locking groove 22 for attaching an insect screen are formed in the upper groove 21, and the indoor leg piece 23 forming the upper groove 21 is longer than the outdoor leg piece 24.

The lower frame 30 is formed with a lower recessed groove 31 that opens downward and a locking groove 32 for attaching an insect screen.
The indoor and outdoor leg pieces 33, 34 forming the indoor/outdoor door 1 are such that the indoor leg piece 33 is longer than the outdoor leg piece 34.

The insect net 51 is stretched across the locking grooves 22 and 32 and the locking groove (not shown) of the vertical stile 40 by being held by a net holding rope 52.

The distance between the opposing end surfaces of the upper and lower screen door rails 6 and 9 is L ₁ , the distance between the tips of the upper and lower indoor leg pieces 23 and 33 is l ₁ , and the distance between the tips of the upper and lower outdoor leg pieces 24 and 34 is l ₂ , the bottom wall (horizontal wall) 12 of the groove 10 of the lower frame 2
and the end face of the lower screen door rail 9 (depth of the groove 10) is D ₁ , and the distance between the bottom wall 25 of the upper groove 21 of the upper stile 20 and the end face of the upper screen door rail 6 (the amount of lift of the screen door) L ₂ is the distance between the end face of the upper outdoor leg piece 24 and the end face of the upper screen door rail 6 (the amount of overlap between the upper screen door rail and the upper outdoor leg piece 24), L ₃ is the distance between the end of the lower screen door rail 9 and the bottom. Distance between the tips of the indoor leg pieces 33 (amount of overlap between the lower screen door rail 9 and the lower indoor leg piece 33)
_{When L 4 is defined as ​ ​ ​ ​} It is set to satisfy equations (1), (2), and (3).

Because of this, as shown in Figure 1, the screen door C
If it is installed between the upper and lower screen door rails 6 and 9, the screen door C will not come off to the outside from the relationship of equations (2) and (3).

In other words, from equation (3), even if the screen door C moves upward by the lifting amount L ₂ , the lower indoor side leg piece 33 will not interfere with the lower screen door rail 9 and come off to the outdoor side, and the screen door C will not move upward by the lifting amount L2. When moved upward by _L2 , the lower stile 30 of the screen door C falls into the groove 10 due to the relationship in equation (1), but due to equation (2), the upper indoor leg piece 23 interferes with the upper screen door rail 6, causing the screen door C to fall into the groove 10. It cannot come off on the outside.

When installing the screen door C, the screen door C is inserted and set from the indoor side so that the lower stile 30 falls into the groove 10, as shown in FIG. At this time, the screen door C does not come off to the outdoor side because the upper indoor leg piece 23 interferes with the upper screen door rail 6 as described above.

From this state, lift the screen door C by L ₂ and fit the upper groove 21 into the upper screen door rail 6, move the lower stile 30 side to the outdoor side, and lower the screen door C to the lower door wheel 35.
All you have to do is make it come into contact with the lower screen door rail 9.

In addition, when removing the screen door C, even if the screen door C is lifted and the bottom wall 25 of the upper groove 21 comes into contact with the lower end surface of the upper screen door rail 6, the indoor side leg piece 33 of the lower groove 31 will not touch the lower screen door rail. 9 and cannot be moved to the outdoor side, but since the outdoor side legs 34 do not interfere with the lower screen door rail 9, the lower part of the screen door is moved to the indoor side from the above condition and dropped into the groove 10, and then moved to the upper outdoor side. The leg piece 24 and the upper screen door rail 6 may be prevented from interfering with each other, and the screen door may be lifted diagonally upward and removed indoors while moving (tilting) the upper part of the screen door toward the indoor side.

Therefore, the screen door will not accidentally fall off to the outdoor side due to strong winds, etc., and the screen door C can be conveniently attached and removed from the indoor side.

In addition, in FIG. 1, 53 is a sliding piece provided on the vertical stile 40 so as to be able to freely slide up and down. It slides upward and acts as a guide so that the screen door slides smoothly.

The present invention is as described above, and it is safe because the screen door C does not accidentally fall off to the outdoor side due to strong winds, etc. from the satsui window frame A, and the screen door can be easily attached and detached from the indoor side. It is suitable as a sash with a screen to be attached to windows.
