Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to sliding windows.

(Prior art) In order to allow the shoji to be attached to and removed from the window frame only from the indoor side, the width C of the outside air side plate that forms the bottom rail groove of the shoji is smaller than the lifting width B of the shoji, and A sliding window whose side panels have a large width A is known as Utility Model Application No. 116143/1983. However, with this idea, unless the indoor rail is made lower than the outdoor rail, the outer shoji cannot be removed to the indoor side using a sliding window with a typical expected width. As a result, rainwater accumulates between the indoor and outdoor rails, crosses the low indoor rails and enters the indoor side, and wind spray enters the indoor side, making it difficult to clear the rain.

Therefore, in order to eliminate this drawback, the outdoor rail on the lower frame should be formed lower than the indoor rail, and should be formed in a step-like shape toward the outdoor side. It will become impossible to remove.

In addition, a piece is provided on the upper frame to prevent the shoji from coming off, but it is installed after the shoji has been erected, but if you forget to install it, the lower part of the outside shoji will come off the outdoor rail and fall between the indoor and outdoor rails. If it falls, it is dangerous because it will fall from the upper part of the shoji to the outside of the room, and the work of installing, erecting, and removing the shoji and the pieces is complicated.

In addition, in a case where the shoji is fitted between the rail parts formed on the upper frame and the lower frame and is run, the fitting depth of the inner flange fitted with the lower frame rail part of the lower stile of the shoji is measured. The fitting depth of the outer flange to the lower rail portion of the lower stile is set to be greater than the fitting depth of the upper frame rail portion of the upper stile, and the fitting depth of the outer flange to the lower rail portion of the lower stile is smaller than the fitting depth of the upper stile and the upper frame rail portion. None, and furthermore, a locking block is removably attached to a position in the lower frame of the rear end of the shoji when the shoji is closed in the window frame, thereby preventing the shoji from leaving the room. The mechanism was opened in 1978.
Known as number 83567. However, with this idea, the outer shoji cannot be installed or removed unless the retaining block of the lower frame is moved from the alignment position of the outer shoji, which is a complicated work.
After installing the outer shoji, the locking block must be moved to the assembly position to function as a locking block, which is undesirable as it may fall off due to forgetting to move it or the outer shoji may be removed from the outside.

Furthermore, the inner flange of the lower stile must be made longer than the outer flange, making it impossible to use the existing lower stile and thus being uneconomical.

(Purpose of the invention) This invention was devised in order to deal with these conventional problems, and it is a sliding window that allows the shoji to be easily installed and removed from the indoor side with the retainer still attached. It is an object of the present invention to provide a sliding window that does not fall off and cannot be removed on the outside of the room.

(Structure of the device) This device includes an upper frame 1 with indoor and outdoor upper rails 6 and 7, an indoor and outdoor lower rail 8 and 9, and a concave groove 27 formed between the indoor and outdoor lower rails 8 and 9 and the base piece 2.

(Example) This invention will be described below based on an example shown in the drawings.

FIG. 1 is a longitudinal sectional view showing a sliding window A according to this invention.

In the drawings, reference numeral 1 indicates an upper frame, 2 indicates a lower frame, 3,
3 indicates both vertical frames. The upper frame 1, the lower frame 2, and both vertical frames 3, 3 are framed in a substantially rectangular shape and constitute a window frame B.

Incidentally, the upper frame 1 has an indoor side mounting groove 4 and an outdoor side mounting groove 5 formed in parallel.

Moreover, an indoor side upper rail 6 and an outdoor side upper rail 7 are provided to hang down from approximately the widthwise center of the indoor side mounting groove 4 and the outdoor side mounting groove 5, respectively.

Also, in the lower frame 2, an indoor lower rail 8 and an outdoor lower rail 9 are erected at positions corresponding to the indoor upper rail 6 and the outdoor upper rail 7 of the upper frame 1, respectively.

The indoor lower rail 8 and the outdoor lower rail 9 are formed in the shape of a step descending from the indoor side toward the outdoor side, and the indoor lower rail 8, the outdoor lower rail 9, and the base piece 2' A concave groove 27 opening toward the upper frame 1 side is formed.

In the above, the inner shoji 10 and the outer shoji 11 are the upper and lower rails 6 on the indoor side of the window frame B, which is framed in a substantially rectangular shape by the upper, lower, and both vertical frames 1, 2, 3, and 3.
8 and between the upper and lower rails 7 and 9 on the outdoor side, respectively, from the indoor side in a sliding manner.

By the way, the upper stile 12 of the inner shoji 10 is formed with an indoor upper recessed groove 13 that loosely fits into the indoor upper rail 6, and the lower stile 14 of this inner shoji 10 has a groove that loosely fits into the indoor lower rail 8. A lower groove 15 on the indoor side is formed, and a door wheel 16 is pivotally supported in the lower groove 15 on the indoor side. This door roller 16 is placed on the indoor lower rail 8, and the inner shoji 10 is made slidable.

Furthermore, the upper stile 12 of the outer shoji 11 is also formed with an upper indoor recess 17 into which the upper rail 7 on the outdoor side fits loosely, and the lower stile 14 also has a lower recess on the indoor side into which the lower rail 9 on the indoor side fits loosely. A groove 18 is formed.

Further, a door wheel 16 is pivotally supported in this indoor lower groove 18, and this door wheel 16 is placed on the indoor lower rail 9. Therefore, the outer shoji 11 can also be slid within the window frame.

By the way, when the outer shoji 11 is installed in the window frame, the indoor side piece 20 that constitutes the indoor side upper concave groove 17 formed from the bottom wall 19 of the upper frame 1 to the upper stile 12 of the outer shoji 11, The distance to the tip of the indoor side piece 29 is L ₃ (the amount of lift of the outer shoji 11).

Further, an upper groove 1 on the outdoor side formed in the upper stile 12 of the outer shoji 11 from the tip of the upper rail 7 on the indoor side of the upper frame 1
The distance to the bottom 21 of 7 is defined as L' ₃ (lifting amount of the outer shoji 11).

By the way, as shown in FIG.
The outdoor side piece 20 of the upper stile 12 of the outer shoji 11 is formed into a long piece that hangs further downward from the lower end of the outdoor side piece 22 and the indoor side piece 22' that constitute the groove 18. Distance between the tip and the tip of the indoor lower end pieces 31, 31 of both vertical frames 30, 30 of the outer shoji 11
_L4 .

Then, as shown in FIG. 1, from the tip of the outdoor lower rail 9 of the lower frame 2
The distance to the tips of the indoor lower end pieces 31, 31 at 0,30 is _L1 (the lower outdoor rail 9 and both vertical frames 30,
(amount of overlap with the indoor lower end pieces 31, 31 of No. 30).

An indoor lower concave groove 18 formed in the lower stile 14 of the outer shoji 11 from the tip of the lower outdoor rail 9 of the lower frame 2
The lower ends of the outdoor side piece 22 and the indoor side piece 22' constituting the
The distance from the bottom wall ₁₉ of the upper frame 1 to the tip of the outdoor hanging piece 26 on the outdoor side of the upper frame 1 is L ₅ , the distance between the upper rail 6 on the outdoor side and the chamber of the upper frame 1 Distance L ₆ from the tip of the inner indoor hanging piece 1' to the tip of the indoor lower rail 8, the outdoor lower rail 9
The distance between the tip and the base piece 2' of the lower frame 1 is D ₁ (depth of the groove 27), and the distance D ₂ between the tip of the indoor lower rail 8 and the base piece 2' of the lower frame 1. .

In the above, L ₃ , L′ ₃ <L ₁ , that is, the lower end piece 3 on the indoor side is larger than the lifting amount of the outer shoji 11.
1 and 31 are long, so even if the outer shoji 11 is erected and removed in a kendon style, the indoor lower end pieces 31, 31 of the outer shoji 11 will come into contact with the outdoor lower rail 1 and come off to the outdoor side and fall off. Moreover, there is no need to provide a stopper on the upper frame 1 to prevent the inner and outer shoji 10 from coming off.

L ₃ , L' ₃ < L ₂ , that is, the outer shoji 11
The length to the tips of the indoor and outdoor pieces 22, 22' of the lower stile 14 of the outer shoji 11 and the indoor lower end pieces 32, 32 of both vertical frames 30, 30 is shorter than the lifting amount, so When installing and removing the shoji 11, the indoor and outdoor pieces 22, 22' and the indoor lower end piece 3
The tips of 2 and 32 can easily straddle the outdoor lower rail 9.

D ₁ −L ₁ <L ₅ −L ₃ , L′ ₃ , that is, the outdoor hanging piece 26 of the upper frame 1 and the outdoor side piece of the upper stile 12 are smaller than the amount that the outer shoji 11 falls into the groove 27. 20 overlap, so the outer shoji 11 is placed in the groove 27 of the lower frame 2.
When it is dropped into the shoji, it abuts and is locked to the outdoor hanging piece 26 of the upper stile 12 of the outer shoji 11 and does not come off to the outdoor side.

L ₄ < L ₆ + D ₂ , that is, the outer shoji 11
Since the distance from the tip of the indoor upper rail 6 and indoor hanging piece 1' of the upper frame 1 to the base piece 2' of the lower frame 2 is longer than the height of When the outer shoji 11 is dropped, the outer shoji 11 can be easily built up and removed from the room without the upper stile 12 of the outer shoji 11 coming into contact with the indoor side upper rail 6 and the indoor hanging piece 1'.

D ₁ <D ₂ , that is, the indoor lower rail 8 is located above the outdoor lower rail 9. There is a relationship between

Therefore, in order to erect the outer shoji 11 from the indoor side inside the window frame B, as shown in FIG. Retainer 28 installed and fixed in groove 27
straddle it and drop it into the groove 27 of the lower frame 2, and place the indoor lower end pieces 31, 31 of both vertical frames 30, 30 of the outer shoji 11 in contact with the base piece 2'. Then, the outer shoji 11 is erected approximately vertically using this contact portion as a fulcrum,
An outdoor upper concave groove 17 formed in the upper stile 12 of the outer shoji 11 is disposed at a position corresponding to the indoor upper rail 7 of the upper frame 1. Then, in this state, the outside shoji 11 is lifted upward, and the outdoor side upper rail 7 is loosely fitted into the outdoor side upper groove 17. The door roller 16, which is pivotally supported in the lower groove 18 on the outdoor side of the lower stile 14, is placed on the lower rail 9 on the outdoor side, and the erection of the outer shoji 11 is completed.

Note that the outer shoji 11 may be removed in the reverse order of the above-mentioned installation method.

At this time, since D ₁ −L ₁ <L ₃ −L ₃ , L′ ₃ , the outdoor side piece 20 of the upper stile 12 comes into contact with the outdoor hanging piece 26 and the outside shoji 11 does not fall off to the outdoor side. .

In addition, even when the outside shoji 11 is installed between the upper and lower rails 7 and 9 on the indoor side, since L ₃ , L' ₃ <L ₁ , it will not fall off to the outside, and the outside shoji 11 will not fall off to the upper frame 1. Since it is not necessary to attach the retaining pieces 10 and 11, it is economical and requires no installation effort.

Also, since L ₄ <L ₆ + D ₂ , when the lower stile 14 of the outer shoji 11 is dropped into the groove 27 and the upper stile 12 side is tilted toward the indoor side, the indoor side upper rail 6 and the indoor hanging piece 1' without interfering with the indoor lower end piece 31 of the lower stile 14,
Even a weak person can erect and remove the heavy outer shoji 11 by simply swinging the upper stile 12 side indoors/outside using the support point as a fulcrum while the shoji 31 is supported by the base piece 2'.

Also, since D ₁ < D ₂ , the indoor lower rail 8
is higher than the outdoor lower rail 9 and has a descending staircase shape from the indoor side to the outdoor side, so that rainwater that enters between the indoor outer lower rails 8 and 9 crosses the indoor lower rail 8 and enters the indoor side. It protects well from rain without splashing or splashing.

In addition, even if a stopper 28 (wind stop plate) is attached and fixed at the matching part of the concave groove 27 of the lower frame 2, that is, at the central position of the lower frame 2, the lower end of the indoor side of the outer shoji 1 Since only the pieces 32, 32 are longer than the indoor/outdoor pieces 22, 22' of the lower stile 14 and the outdoor lower end pieces 32, 32 of both vertical frames 30, 30, there is a gap between the indoor lower end pieces 31, 31 of the outer shoji 11. By straddling the retainer 28, installation and removal can be easily performed from the indoor side, and when the inner and outer shoji 10, 11 are closed, the lower end pieces 31, 31 on the indoor side always remain in the retainer 28.
Due to its location, the inner and outer shoji cannot be removed, providing good security.

This has the above effects.
