Next, the regulation part 70 with which the sliding window 1 which concerns on this embodiment is provided is demonstrated in detail.
FIG. 4 is an enlarged view of the restricting portion 70 of the sliding window 1 according to the present embodiment. As shown in FIG. 4, the restricting portion 70 includes a first inner engaging portion 711a, a second inner engaging portion 711b, a closing member 712 as a thermal fuse, a first outer engaging portion 721a, and a second An outer engagement portion 721b.

The first inner engaging portion 711a is formed by a step on the outdoor side surface of the inner summon bowl main body 231a. More specifically, a concave portion 231b is formed on the surface on the outdoor side of the inner sump bowl main body 231a facing the inner smoke return piece 710, thereby causing a step generated at the boundary with the surface on the outdoor side of the glass groove portion 230. A first inner engagement portion 711a is formed.
The second inner engagement portion 711b is formed by a step formed by a bent portion 710a in which the tip portion of the inner smoke return piece 710 is bent toward the inner summing bowl 23 side.
Note that the first inner engagement portion 711a and the second inner engagement portion 711b are disposed to face each other, and the positions in the finding direction are substantially the same.

  The closing member 712 as a thermal fuse is inserted between the inner smoke return piece 710 and the recessed portion 231b on the outdoor side surface of the inner summit bowl main body 231a, and the first inner engaging portion 711a and the second inner engaging portion. Both engaging portions of 711b are closed. The closing member 712 is substantially U-shaped in cross-sectional view, and is formed in a reverse taper shape in which both open end portions are slightly inclined outward toward the distal end side. Further, the closing member 712 includes a convex portion 712a on the outer side on the bottom surface side opposite to the open side. The convex portion 712 a is fitted in a mounting hole 710 b formed in the inner smoke return piece 710.

  The thickness dimension of the both end parts on the open side of the closing member 712 is set to be equal to or higher than the height dimension of each step forming the first inner engagement part 711a and the second inner engagement part 711b. Accordingly, the closing member 712 closes the first inner engagement portion 711a and the second inner engagement portion 711b, so that the first inner engagement portion 711a and the second inner engagement portion are closed when the temperature is lower than the predetermined temperature. The portion 711b is prohibited from engaging with a first outer engagement portion 721a and a second outer engagement portion 721b, which will be described later.

  The closing member 712 is made of a resin member such as nylon, for example. Therefore, when the inner sump bowl 23 and the outer sump bowl 33 are exposed to a high temperature due to a fire or the like and become above the predetermined temperature, the closing member 712 is melted, deformed, and dropped. Accordingly, a first outer engagement portion 721a or a second outer engagement portion 721b, which will be described later, can be engaged with the first inner engagement portion 711a or the second inner engagement portion 711b.

  Here, FIG. 5 is a diagram illustrating a method of attaching the closing member 712. As shown in FIG. 5, the closing member 712 is attached by sliding from the open side (right side) of the inner smoke flare piece 710 in the direction of finding and inserting until the convex portion 712a is fitted into the attachment hole 710b. . At this time, since the closing member 712 is formed in a reverse taper shape as described above, the closing member 712 is smoothly inserted between the inner smoke return piece 710 and the concave portion 231b on the outdoor side surface of the inner summon bowl 231a. Mated.

  Returning to FIG. 4, the first outer engagement portion 721 a and the second outer engagement portion 721 b are formed by a protrusion 720 a that is formed at the tip of the outer smoke return piece 720 and protrudes indoors and outdoors. More specifically, the first outer engagement portion 721a is formed by a step generated at the boundary between the projection 720a and the outer smoke return piece 720 on the indoor side. Further, a second outer engagement portion 721b is formed by a step generated at the boundary between the projection portion 720a and the outer smoke return piece 720 on the outdoor side.

Next, operation | movement of the sliding window 1 of this embodiment provided with the said control part 70 is demonstrated.
FIG. 6 is a diagram illustrating the operation of the sliding window 1 according to the present embodiment. In more detail, it is a figure which shows operation | movement when the sliding window 1 is exposed to high temperature by the fire which generate | occur | produced on the outdoor side.

First, when a fire occurs on the outdoor side, the outer summon basket 33 is exposed to a higher temperature than the inner summit bar 23. Then, due to thermal expansion, the outer summoning bowl 33 extends and bends more, and a larger warp occurs. As a result, as shown in FIG. 6, as the central part of the extending direction of the inner summit bar 23 and the outer summit bar 33, the two sump bars are deformed and moved in the direction away from each other in the prospective direction. On the other hand, as the upper and lower end portions of the inner summoning bowl 23 and the outer summoning bowl 33, the two summoning bowls are deformed and moved in directions close to each other in the direction of finding.
At the same time, the two summoning bowls are deformed and moved in a direction away from each other in the direction of finding under the influence of the extension deformation of the upper and lower bowls.
At this time, since the closing member 712 is made of resin as described above, it melts and falls off. That is, the restriction on the engagement of each engagement portion is released.

  Therefore, as shown in FIG. 6, the inner smoke return piece 710 and the outer smoke return piece 720 engage with each other in the prospective direction at the center in the extending direction of the two summons. Thereby, the deformation | transformation movement of the direction which leaves | separates to the prospective direction of both summoning bowls is suppressed. Further, the second inner engagement portion 711b and the second outer engagement portion 721b engage in the direction of finding. Thereby, the deformation | transformation movement of the direction which leaves | separates in the direction which finds both summoning bowls is suppressed. By the above, it is suppressed that a clearance gap generate | occur | produces between both summoning cups, and fire prevention property improves.

  Further, as shown in FIG. 6, at the upper and lower ends of the extending direction of the two summoning tubs, the inner smoke returning piece 710 contacts and engages with the indoor side surface of the outer summing bowl 33, and the outer smoke returning piece 720. Comes into contact with and engages with the outdoor side surface of the inner summon bowl 23.

Is prohibited. In addition, when both summon bowls are exposed to a high temperature due to a fire or the like and become above the predetermined temperature, the closing member 712 melts and falls off, and the first inner engagement portion 711a and the second inner engagement are performed. Since the portion 711b is exposed, the above-described effect is more reliably achieved.

[Second Embodiment]
Next, a second embodiment of the present invention will be described in detail with reference to the drawings.
The sliding window 1A according to the second embodiment of the present invention has the same configuration except that the configurations of the inner smoke returning portion 71A, the outer smoke returning portion 72A, and the regulating portion 70A are different from the first embodiment. More specifically, the restriction portion 70 is provided in the smoke return portion in the first embodiment, whereas the inner engagement device 700 constituting the restriction portion 70A is provided separately from the smoke return portion in the present embodiment. Is different. Hereinafter, the same configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof is omitted.

FIGS. 7A and 7B are diagrams showing a summoning bowl of the sliding window 1A according to the second embodiment, in which FIG. 7A is a sectional view and FIG. 7B is a side view. In addition, the side view of (b) is a left side view of (a), and the side face of the inner summon bowl main body 231a is omitted for convenience.
As shown in FIG. 7A, the inner smoke returning portion 71A is provided with a first inner engaging portion 711a and a second inner engaging portion 711b on the outer side surface of the inner smoke returning piece 710A and the inner summoning bowl 23. The configuration is the same as that of the internal smoke return portion 71 of the first embodiment, except that it is not different from the first embodiment.
Further, the outside smoke returning portion 72A is the first embodiment except that the outside smoke returning piece 720A is not provided with the first outside engaging portion 721a and the second outside engaging portion 721b from the first embodiment. It is the structure similar to the external smoke return part 72 of a form.

  The restricting portion 70A is a restriction of the first embodiment configured by a first inner engaging portion 711a, a second inner engaging portion 711b, a closing member 712, a first outer engaging portion 721a, and a second outer engaging portion 721b. This is very different from the unit 70. The restricting portion 70 </ b> A of the present embodiment includes an outer smoke return piece 720 </ b> A and an inner engagement device 700.

FIG. 8 is a perspective view of the inner engagement device 700 according to this embodiment. More specifically, it is an exploded perspective view of the inner engagement device 700 with the cover member 705 removed.
As shown in FIG. 8, the inner engagement device 700 includes a main body portion 701, a rotating plate 702, a shaft portion 703, a winding spring 704, and a cover member 705 instead of a closing member 712 as a thermal fuse. Prepare.
Except for the cover material 705, each component of the inner engagement device 700 is made of an iron metal member such as stainless steel.

  The main body 701 is formed in a rectangular plate shape. The main body portion 701 is screwed to the side surface of the inner sump bowl main body 231a on the side of the glass groove 230 by screws 701a and 701a.

  The rotating plate 702 is formed in an elliptical plate shape. The rotating plate 702 has a shaft hole 702a formed on one end side in the longitudinal direction. The rotary plate 702 is rotatably supported by the main body 701 by inserting and caulking the shaft 703 into the shaft hole 702a.

  The winding spring 704 is wound around the shaft portion 703, and one end thereof is fixed to the convex portion 701 b of the main body portion 701. Further, the other end of the winding spring 704 is fixed to a hole 702 b formed on the other end side in the longitudinal direction of the rotating plate 702. As a result, a biasing force in the rotation direction (counterclockwise in FIG. 8) about the shaft portion 703 is applied to the rotating plate 702.

  The cover member 705 is formed of a resin member having a substantially L shape in cross section. The cover material 705 is attached to the main body 701 so as to cover a part of the surface and the side surfaces of the rotating plate 702 and the shaft 703 attached to the main body 701. That is, the cover member 705 blocks the rotation plate 702, thereby prohibiting the engagement between the rotation plate 702 and the external smoke return piece 720A when the temperature is lower than the predetermined temperature. At this time, the rotation plate 702 is covered with the cover member 705 in a state in which the urging force in the rotation direction about the shaft portion 703 is applied by the winding spring 704, so that the rotation is restricted. .

  Further, the cover member 705 includes locking portions 705a and 705a that are inclined downward toward the main body portion 701 at both ends in the longitudinal direction. The cover member 705 is fixed to the main body portion 701 by engaging the substantially L-shaped claw portions 701c and 701c provided at both ends in the longitudinal direction of the main body portion 701 with the engaging portions 705a and 705a.

  In addition, the opening 231c is formed in the site | part to which the inner engagement apparatus 700 is attached among the outdoor side surfaces of the inner summon bowl main body 231a. The side surface of the cover member 705 is inserted through the opening 231c.

The difference of the operation of the sliding window 1A according to the present embodiment having the above-described configuration from the first embodiment will be described.
FIG. 9 is a view showing the operation of the sliding window 1A according to the present embodiment, in which (a) is a cross-sectional view and (b) is a side view. More specifically, it is a diagram showing an operation when the sliding window 1A is exposed to a high temperature due to a fire occurring on the outdoor side. 9 (a) shows a cross-sectional view of the central portion in the extending direction of both summons, and the side view of (b) is a left side view of (a). The side surface of the summon bowl main body 231a is omitted.

As described above, in the central part of the extending direction of the two summoning bowls, the two summoning bowls are deformed and moved in the direction away from each other in the prospective direction. At the same time, the two summoning bowls are deformed and moved in a direction away from each other in the direction of finding under the influence of the extension deformation of the upper and lower bowls.
At this time, since the cover member 705 is made of a resin member, it melts and falls off. That is, the rotation restriction of the rotating plate 702 is released, and the rotating plate 702 rotates. Then, as shown to (a) and (b) of FIG. 9, the rotating plate 702 protrudes from the opening 231c formed in the outdoor side surface of the inner summon bowl main body 231a.

  Therefore, in the center part of the extending direction of both summoning tubs, the inner smoke return piece 710A and the outer smoke return piece 720A are engaged with each other in the prospective direction. Thereby, the deformation | transformation movement of the direction which leaves | separates to the prospective direction of both summoning bowls is suppressed. Further, the protruding rotating plate 702 contacts and engages the outer smoke return piece 720A in the direction of finding. Thereby, the deformation | transformation movement of the direction which leaves | separates in the direction which finds both summoning bowls is suppressed. By the above, it is suppressed that a clearance gap generate | occur | produces between both summoning cups, and fire prevention property improves.

  In addition, also in the upper and lower ends of the extending direction of the two summoning bowls, the deformation movement in the direction away from the finding direction of the two summoning bowls is suppressed by the same operation as the central part. Similarly to the first embodiment, the inner smoke return piece 710A is in contact with and engaged with the indoor side surface of the outer summing bowl 33, and the outer smoke return piece 720A is in contact with the outdoor side face of the inner summing bowl 23. By engaging with each other, deformation movement in a direction away from the prospective direction of the two summons is suppressed.

  Returning to (a) of FIG. 7, the protruding position of the rotating plate 702 indicated by a broken line in the drawing is set so as to be closer to the door end (right side) of the glass 26 than the outer smoke return piece 720 </ b> A. Furthermore, the distance D between the projecting position of the rotating plate 702 and the outer smoke return piece 720A is set to be smaller than the overlap margin of the overlapping portion in the direction of finding the inner smoke return piece 710A and the outer smoke return piece 720A. Thereby, it operates reliably as described above.

  According to the present embodiment, the same effects as those of the first embodiment are exhibited.
