Description

[Detailed explanation of the idea] The present invention relates to a window suitable for the inner window of a double-glazed window.

Since conventional double-paned windows have wide window frames, it is not possible to construct double-paned windows in ordinary houses using only internally installed type sashes as shown in FIG. That is, in FIG. 1, which is a vertical vertical cross-sectional partial view,
F is outdoors, R is indoors, and 1 is an outer wall. Two shoji screens 2, 2 are designed to run in a direction perpendicular to the plane of the drawing. The window upper frame 3 is fixed to the lower surface of the wooden frame 4, the outdoor F side edge 5 of the upper frame 3 is located almost directly below the outdoor side surface 6 of the wooden frame 4, and the indoor R side edge 7 is fixed to the wooden frame 4. It is in contact with the upper frame 8 of the picture frame. And the width W of the wooden frame 4
For example, is about 105 mm, and the width W ₁ of the upper frame 3 is about 70 mm.
Therefore, the width W ₂ of the upper frame 8 of the picture frame is approximately 40 mm. When trying to make such windows into double glazed windows,
If the upper frame 3a for the inner window is attached to the lower surface of the frame upper frame 8, since the width _W2 of the frame upper frame 8 is narrow, the upper frame 3a will protrude into the room R. Therefore, considering the interior appearance, etc., the frame The inner window upper frame 3a cannot be attached to the upper frame 8. For the above reasons, when configuring a conventional double window, the upper frame 3 of the internal type is used as the upper frame for the inner window, and the upper frame 3b for the outer window is used as the upper frame for the outdoor window, as shown in Fig. 2.
It is attached to the wooden frame 4 in a semi-external or external type by protruding to the side.

The purpose of this invention is to provide a window with a narrow frame width, whereby both the inner and outer windows are of the internal type.
An embodiment of the present invention is described below with reference to the drawings.

In FIG. 3, which is a schematic horizontal cross-sectional view, an inner window A and an outer window B are provided between a pair of vertical columns 10 and 11. The two shoji screens B ₁ and B ₂ of the outside window B are of the sliding type as in the past. The two shoji A ₁ and A ₂ of the inner window A are lined up in a line without any discrepancy in the closed state shown in FIG. 3, and the detailed structure is as follows.

In FIG. 4, which is a partial cross-sectional view of FIG. 3, the horizontal upper wall 16 of the window upper frame 15 is fixed to the lower surface of the wooden frame upper frame 8 with wood screws (not shown). The frame upper frame 8 is fixed to the lower surface of the wooden frame 4 near the indoor wall 9, as in the conventional case. The width W ₂ of the upper frame 8 of the frame is narrow as in the conventional case, for example, approximately
It is 40mm. The window frame 15 is made of extruded aluminum, for example, and its width W ₃ is narrower than the frame width W ₂ . Side walls 17 and 18 extend downward from both edges of the upper wall 16, and a plate-shaped rail support portion 20 extends downward from the middle part of the upper wall 16 in the width direction.
extends in one piece. A plate-shaped first rail 21 and a second rail 22 extend horizontally from the lower end of the support part 20 toward the outdoor F side and the indoor R side, respectively.
The side edges of both rails 21 and 22 on the side away from the support portion 20 are bent upward to form side walls 23 and 24. A tire 25 is mounted on the rail 21 on the outdoor F side, and a rotating shaft 26 of the tire 25 is mounted on the side wall 1.
The portion protruding toward the 7 side is supported by the upper end of a bracket 27 having an L-shaped cross section. Bracket 2
The horizontal part 29 of No. 7 is extended from the lower end of the vertical part 30 of the bracket toward the R side of the room, and is attached to the first shoji with screws 31.
It is fixed to the top surface of the upper stile 32 of _A1 . Upper stile 3
2 A short plate-shaped projection 3 is formed from the side edge of the top surface on the indoor R side.
3 protrudes upward, and the tip of the horizontal portion 29 is in contact with the protrusion 33. A vertical plate-shaped side wall extension 35 extends from the outdoor F side edge of the upper surface of the upper stile 32 to the vicinity of the tire support shaft 26, and the bracket vertical part 30 is in contact with the extension 35. As is clear from these descriptions, the bracket 27 is provided integrally with the upper stile 32. The extension part 35 has a groove in the upper part that opens toward the side wall 17, and a mohair seal 36 fitted into the groove is in contact with the side wall 17. The width W ₄ of the lower window frame 40 is also approximately the same as the width W ₃ of the upper frame 15 . The lower frame 40 is fixed to the upper surface of the lower wooden frame 4a (or the lower frame of the frame) with wood screws (not shown), and a shallow guide groove 41 is provided in the middle part of the upper surface of the lower frame 40 in the width direction. . A vertical support shaft 42 is provided in the groove 41.
A guide roller 43 attached to the lower part of the guide roller 43 is fitted in a rotatable manner. The upper part of the support shaft 42 is supported by the lower end of the lower stile 45 of the window _A1 . From the lower edge of the side wall 46 on the indoor R side of the lower stile 45, the horizontal part 47 is
A plate-like vertical portion 49 extends upward from the tip of the horizontal portion 47, and a groove 50 with the horizontal portion 47 as a bottom wall is formed between the lower part of the side wall 46 and the vertical portion 49. There is. A vertical wall 52 for supporting a mohair seal 51 extends upward from the edge of the lower frame 40 on the outdoor F side, and the seal 51 is attached to the lower frame 45 on the outdoor F side.
contact from the side.

Next, the second shoji A2 will be explained with reference to FIG. 5, which is a partial cross-sectional view of _FIG . In FIG. 5, the tire 5 riding on the rail 22 on the R side of the room
The rotational support shaft 56 of No. 5 has a portion that protrudes from the tire 56 toward the side wall 18 and is supported by the upper end of the vertical portion 58 of the bracket 57. A horizontal portion 59 extends from the lower end of the vertical portion 58 toward the outdoor F side.
is rotatably attached to the upper surface of the arm 61 by a vertical rivet 60. The arm 61 is a member having a U-shaped cross section that opens downward, and extends in a horizontal direction as shown in FIG. The shoji can be moved by the support shaft 62 having
It is rotatably supported on the upper surface of the upper stile 63 of _A2 . As shown in Fig. 7, which is an enlarged schematic diagram of Fig. 3,
The arms 61 are provided one each at the door edge (left end in FIG. 7) and near the door edge of the shoji A ₂ , and when the shoji A ₂ is aligned with the shoji A ₁ as shown by the solid line, The arm 61 is in a position parallel to the upper stile 63 and with the tire 55 approaching the other arm 61. As shown in FIG. 5, a plate-shaped vertical portion 66 extends from the indoor R side edge of the upper surface of the upper stile 63 to a point slightly above the arm 61.
The lower end of the bracket vertical portion 58 is in contact with the upper end. Although not shown, the arm 61 and the upper stile 6
A spring is provided between the arms 61 and 3, and the spring urges the arm 61 to maintain a position parallel to the upper stile 63 as shown in the figure. Vertical section 66
A horizontal portion 67 extends from the upper end toward the indoor R side, and a vertical portion 69 extending upward from the tip of the horizontal portion 67 holds a mohair seal 70 that contacts the upper frame side wall 18 from the indoor R side.

The lower stile 71 of the shoji A ₂ is not connected to the window lower frame 40 and remains free. Lower stile 71
From the lower part of the side wall 72 on the outdoor F side, a horizontal portion 73 protrudes toward the outdoor F side, and from the tip of the horizontal portion 73, a vertical portion 75 protrudes downward. As shown in FIG. 7, the end faces a ₁ , a ₂ of both shoji screens A ₁ , A ₂ are inclined downward to the left in the figure, that is, away from the support shaft 62 as they move toward the room R side.

Furthermore, as is clear from FIGS. 4 and 5, the bracket vertical portion 30 in FIG.
1 and 22, whereas the vertical part 58 of the bracket in Fig. 5 is short, and the main body of the shoji _A2 (the part from the upper stile 63 to the lower stile 71) ) is deflected toward the room R side in the direction of arrow M as described later, the bracket horizontal portion 59 and arm 61 can pass through the gap 77 in FIG. 4.

Next, the deflection operation of the shoji _A2 in the direction of the arrow M will be explained. In FIG. 7, when the shoji A ₂ is pulled toward the room R side, the arm 61 rotates relatively on the upper stile 63 around the support shaft 62, and the bracket 57 rotates around the rivet 60. 61, and by these operations, the shoji A ₂ moves toward the indoor R side with respect to the shoji A 1 by the arrow M, as shown by the two-dot chain line A ₂ ', while keeping the tire 55 fitted on the rail ₂₂ so that it can run freely.
bias in the direction.

When opening the inner window A, open the door tip part 8 of the shoji A ₂ .
0 toward the indoor R side, and using the above-mentioned biasing action, make the door edge portion 80 protrude toward the indoor R side as shown in FIG. ), groove 50 of shoji A ₁ and shoji A ₂ (5th
The end faces of the vertical portions 75 shown in Figure) should be lined up. Next, when we apply a force in the opening direction P to the shoji A ₂ in Figure 8, we get
As shown in Figure 9, the main body of shoji A ₂ has an indoor radius that is higher than that of shoji A ₁ .
Run at a nearby location. In this case, the bracket horizontal portion 59 in FIG. 5 and the arm 61 portion in the vicinity thereof pass through the gap 77 in FIG. 4. Also, since the vertical part 75 of the shoji A ₂ passes through the groove 50, the shoji A ₂
The lower part will not swing significantly toward the indoor R side or the outdoor F side. In addition, in the closed state shown in Figure 7, the shoji
Even when a force in the opening direction P is applied to A ₂ , the shoji A ₂ is deflected toward the room R side as shown in FIG. 8 due to the reaction force generated on the inclined end surfaces a ₁ and a ₂ . In order to close the shoji A ₂ from the open state shown in FIG. 9, it is sufficient to move the shoji A ₂ to the position shown in FIG. 8. Then arm 6 in Figure 7
1 rotates in the opposite direction to the opening operation due to the elasticity of a spring (not shown), and the shoji A ₂ returns to its original closed state. Note that the lower end of shoji A ₂ is in a free state, but in the closed state, shoji A ₂ is
By locking the shoji A ₁ etc., the shoji A ₂ can be securely fixed.

As explained above, according to the present invention, the window upper frame 1
5, a first rail and a second rail 21, 22 are rigidly provided close to each other and extend parallel to each other, and the first and second shoji A are arranged on the same plane in the closed state.
1 and A2 are arranged below both the rails 21 and 22 with a vertical gap 77 between them, and the first bracket 27 is arranged in a posture extending vertically at a position on the outdoor side of the above gap 77. A first running part (tire 25) running on the rail 21 and the first shoji A1 are connected so that they cannot move relative to each other by the first bracket 27, and a second running part (tire 55) running on the second rail 22 is connected. and a second shoji A2 are connected via a connecting mechanism, and a second bracket 5 is attached to the connecting mechanism and extends vertically at a position on the indoor side of the gap 77.
7, and a horizontal arm 6 located within the gap 77.
1, a second running section (tire 55) is attached to the upper end of the second bracket 57, and the second bracket 5
7 is connected to one end of the arm 61 relatively rotatably in the horizontal direction, the other end of the arm 61 is connected to the upper end of the second shoji A2 so as to be relatively rotatable in the horizontal direction, and the first shoji A1 A guide part (guide roller 43) is provided at the lower end of the window frame 40 to prevent movement in the width direction of the window frame.
The lower end of the second shoji A2 on the indoor side and the lower end of the second shoji A2 on the outdoor side are mutually prevented from moving in the width direction of the window frame when the second shoji A2 is biased toward the indoor side with respect to the first shoji A1. Engagement portion 5 that engages in a blocked state
It is characterized by having a value of 0.75.

According to the above configuration, the second shoji A2 is connected to the tire 55
Since the rails 21 and 22 can be moved closer to each other and configured as if they were one rail, the window frame widths W3 and W4 can be opened and closed by shifting them toward the indoor R side relative to the running parts of can be made smaller. Therefore, the window according to the present invention can be installed in a narrow part such as the upper frame 8 of the frame, and as shown in Fig. 3, the inner window A can be installed in a part closer to the indoor side than the external window B of the internal type. Moreover, the inner window A can be prevented from protruding toward the interior R side.

Furthermore, since only the shoji A2 moves indoors while the rail 22 remains stationary, the rails 21 and 22 can be kept close to each other in a compact state whether the shoji A2 is closed or opened. , so there is no risk of deterioration in appearance.

Furthermore, as described above, in the present invention, the guide portion (guide roller 43) guided by the window lower frame 40 is provided only on one shoji A1, and the other shoji A2 is provided with a guide portion (guide roller 43) that is guided by the window lower frame 40. An engaging portion (vertical portion 75) that engages with A1 is provided. Therefore, compared to the case where a movable connection mechanism similar to the arm 61 is provided between the lower part of the shoji A2 and the window sill 40, the vertical width of the window sill 40 can be made smaller to reduce the opening height of the window sill. It can be made larger and the appearance can be improved in this respect as well. Also, window bottom frame 40 and shoji A
The structure of 2 can be simplified.

Further, according to the above configuration, when opening and closing the shoji A1 and A2, the tires 25 and 55 run on the upper rails 21 and 22 of the shoji A1, and the tires 25 and 55 run on the upper rails 21 and 22 of the shoji A1 and the rail 2.
The arm 61 moves through the gap 77 between 1 and 22. In addition, in the closed state, the entire arm 61 is
It is accommodated in the gap 77 above the shoji A2.

In this way, in this invention, both shoji A1 and A2
Since the arm 61 and the tires 25, 55 can be positioned almost directly above the window, the width of the entire window can be reduced, and the appearance can be improved in this respect as well. In other words, by using the present invention, it is possible to make the entire double-paned window an internal type in consideration of the appearance, or to construct a double-paned window using a ready-made internal type window 3 as shown in Fig. 1. can.

Note that the window according to the present invention can also be used alone (as a window other than double-paned windows).
