Description

  The present invention relates to a sash in which an internal and external shoji is housed in a frame provided in an opening of a building, and in particular, a sash that prevents a gap from being generated by maintaining the positional relationship between the frame and the shoji even when exposed to high temperatures in the event of a fire. About.

  In the sash provided in the opening of the building, a sliding sash is widely used, in which internal and external shojis are housed in a frame. A sash including a sliding sash is required to have a fireproof performance that maintains a closed state for a predetermined time or more even when a fire occurs. In order to ensure sufficient fire prevention performance, even if the sash is exposed to high temperatures, a gap is created between the frame and the shoji by maintaining the positional relationship between the frame and the shoji that make up the sash. It is important not to let them.

  In the sash, not only a resin sash but also a metal sash, resin members are used in various places. Since such a resin member melts when exposed to a high temperature during a fire, it is necessary to maintain the positional relationship between the frame and the shoji even if the resin member melts.

  FIG. 3 shows an enlarged cross-sectional view of the inner shoji 2 near the downarm 22. As shown in this figure, a metal inclined surface member 24 is further integrated with the vertical pulling member 25 provided on the vertical rod 22. The inclined surface member 24 has a vertical inclined surface portion 24b that is close to and faces the intermediate fin portion 12d of the vertical frame 12, and the vertical inclined surface portion 24b is formed in an inclined surface shape from the outdoor inner peripheral side toward the indoor outer peripheral side. Has been.

  4 is a perspective view of a member in which the inclined surface member 24 and the vertical pulling member 25 are integrated, and FIGS. 5 and 6 are exploded perspective views of the inclined surface member 24 and the vertical pulling member 25, respectively. The inclined surface member 24 made of a metal material includes a base portion 24a fixed to the outer peripheral surface of the vertical rod 22, and the vertical inclined surface portion 24b is inclined from the base portion 24a and formed on both sides thereof. A fitting portion 24d for fixing the vertical pulling member 25 is formed in a vertical rising shape.

  A fixing hole 24c for screwing the vertical rod 22 is formed in the base 24a. The fixing hole 24c is formed so that the edge is inclined, and the head of the screw 28 that fixes the inclined surface member 24 does not protrude from the thickness of the base 24a. This prevents the screw 28 from interfering with the intermediate fin portion 12d. Further, the fixing hole 24c is formed in a slightly elongated shape so that the position of the inclined surface member 24 can be adjusted. Thereby, the positional relationship between the vertically inclined surface portion 24b and the intermediate fin portion 12d can be accurately adjusted.

  The vertical drawing member 25 has an inclined drawing surface portion 25 a formed on the side located at the tip of the vertical rod 22. The pulling surface portion 25a comes into contact with the distal end portion of the intermediate fin portion 12d when closing the inner shoji 2.

  As shown in FIG. 6, the vertical pulling member 25 has a protruding fitting protrusion 25b on the surface opposite to the side on which the pulling surface 25a is formed. When the fitting protrusion 25b is fitted to the fitting portion 24d of the inclined surface member 24, the inclined surface member 24 and the vertical pulling member 25 are integrated. In addition, a vertical hook fixing portion 25c that is fitted to the vertical rod 22 is also formed at both ends of the vertical pulling member 25, whereby the vertical pulling member 25 is fixed to the vertical rod 22 as well. The

  When a fire occurs and the sash is exposed to a high temperature, the resin vertical pulling member 25 is melted and melted down as described above. Further, as the temperature rises, each of the brazing materials constituting the casing 4 also greatly increases. When the upper rod 20 and the lower rod 21 extend in the longitudinal direction, the vertical rod 22 moves toward the inner peripheral surface 12 a of the vertical frame 12. FIG. 7 shows an enlarged cross-sectional view of the inner shoji 2 near the downarm 22 in the state at the time of the occurrence of a fire.

  As shown in FIG. 7, even when a fire occurs, the inclined surface member 24 made of a metal material is fixed to the vertical gutter 22 as it is. When the vertical rod 22 moves to the inner peripheral surface 12a side of the vertical frame 12, the vertical inclined surface portion 24b of the inclined surface member 24 comes into contact with the tip end portion of the intermediate fin portion 12d, and the vertical rod 22 further moves to the inner peripheral surface of the vertical frame 12. Along with the movement to the 12a side, the vertical rod 22 is pressed indoors by the intermediate fin portion 12d along the inclination direction of the vertical inclined surface portion 24b. As a result, the indoor side surface of the vertical rod 22 is pressed against the airtight material 12g provided on the indoor fin portion 12f of the vertical frame 12, so that no gap is generated between the vertical rod 22 and the vertical frame 12. it can. That is, it is possible to maintain the fireproof performance of the downarm 22.

  Further, since the tip end portion of the intermediate fin portion 12d is formed in an inclined surface shape facing the vertical inclined surface portion 24b, when the inclined surface member 24 approaches the intermediate fin portion 12d side, the vertical inclined surface portion 24b. Can be reliably guided toward the indoor side of the intermediate fin portion 12d, and the fireproof performance can be more reliably exhibited.

  As described above, the vertical inclined surface portion 24b is provided on the outer peripheral surface of the vertical rod 22 so as to be close to and opposed to the intermediate fin portion 12d of the vertical frame 12, so that the vertical wall 22 can be reliably moved to the indoor side with a simple configuration. Can be achieved. In addition, since the vertically inclined surface portion 24b is in close contact with the intermediate fin portion 12d in a state in which the inner shoji 2 is closed at a normal time, parts for fire prevention do not hinder the opening and closing of the shoji at the normal time, It can function only in the event of a fire. In addition, although the drawing structure of the inner shoji 2 was demonstrated here, it is the same structure also about the outer shoji 3, and the same effect can be acquired. Also in the following embodiments, the inner shoji 2 and the outer shoji 3 have the same pulling structure.

  In the present embodiment, the inclined surface member 24 and the vertical pulling member 25 are integrated and fixed to the vertical rod 22, but they are not necessarily integrated, and are provided separately on the outer peripheral surface of the vertical rod 22.

  FIG. 8B shows a state in which a fire has occurred and the vertical rod 22 has approached the vertical frame 12 side. When a fire occurs and the vertical rod 22 approaches the inner peripheral surface 12a of the vertical frame 12, the vertical inclined surface portion 24b hits the intermediate fin portion 12d, and the vertical rod 22 approaches the inner peripheral surface 12a of the vertical frame 12. Then, the root surface portion 24f is in contact with the indoor side surface of the intermediate fin portion 12d. Since the positional relationship between the intermediate fin portion 12d and the root surface portion 24f is as described above, the root surface portion 24f is pressed indoors by the intermediate fin portion 12d, and the indoor side surface of the vertical rod 22 is against the airtight material 12g of the indoor fin portion 12f. The same effect as the embodiment shown in FIGS. 3 and 7 can be obtained.

  In this embodiment, the inclined surface member 24 is provided with the longitudinally inclined surface portion 24b. However, the longitudinally inclined surface portion 22 itself may be provided with the vertically inclined surface portion.

This figure shows the state at the time of fire occurrence like FIG. 7, and the vertical drawing member 25 is melted and melted off at this time. When the vertical pulling member 25 does not exist and the vertical rod 22 moves to the vertical frame 12 side, the vertical inclined surface portion 22d formed on the vertical rod 22 contacts the indoor side of the intermediate fin portion 12d of the vertical frame 12. In contact with each other, it is pressed indoors by the intermediate fin portion 12d. Thereby, the indoor side surface of the vertical rod 22 is pressed against the air-tight material 12g of the indoor fin portion 12f, and it is possible to prevent a gap from being generated between the vertical rod 22 and the vertical frame 12, and to improve the fire prevention performance. .

  Furthermore, you may make it provide a vertical inclined surface part in the vertical frame 12 side instead of the vertical rod 22 side. FIG. 11 shows an enlarged cross-sectional view of the vicinity of the vertical rod 22 having the vertical inclined surface portion of the fourth embodiment. As shown in this figure, the intermediate fin portion 12d of the vertical frame 12 has a root position that is closer to the indoor side than the one shown in FIG. In the middle position on the front end side from the root surface portion 12i, there is an inclined frame-side vertical inclined surface portion 12h that extends from the indoor root side to the outdoor front end side. The front end side of the frame-side vertical inclined surface portion 12h is formed to be a position that functions as the intermediate fin portion 12d, that is, a central position of the fin swallowing portion 22c of the vertical rod 22.

  The intermediate fin portion 12d of the vertical frame 12 can be brought into contact with the vertical pulling member 25 in a normal state to function as the intermediate fin portion 12d. On the other hand, when a fire occurs, the function of drawing the vertical gutter 22 toward the indoor side can be exhibited. FIG. 12 shows an enlarged cross-sectional view of the vicinity of the vertical rod 22 in a state where the vertical inclined surface portion of the fourth embodiment functions. This figure shows the state at the time of fire occurrence like FIG. 7, and the vertical drawing member 25 is melted and melted off at this time.

  When the vertical pulling member 25 does not exist and the vertical rod 22 moves to the vertical frame 12 side, the outer peripheral end of the indoor side surface of the vertical rod 22 comes into contact with the frame-side vertical inclined surface portion 12h of the intermediate fin portion 12d. Pressed indoors. Since the root surface portion 12i of the intermediate fin portion 12d is formed at a position adjacent to the outdoor side of the surface obtained by extending the inner side surface of the vertical rod 22 in the normal state to the outer peripheral side, it contacts the inner peripheral surface 12a of the vertical frame 12. In the contacted state, it contacts the root surface portion 12i of the intermediate fin portion 12d. Thereby, the indoor side surface of the vertical rod 22 is pressed against the air-tight material 12g of the indoor fin portion 12f, and it is possible to prevent a gap from being generated between the vertical rod 22 and the vertical frame 12, and to improve the fire prevention performance. .

As shown in the figure, an upper anti-vibration component 26 made of resin is provided at the upper end portion of the vertical rod 22. The upper anti-vibration component 26 is narrower than the rail guide portion 20b of the upper collar 20 and is slidable along the longitudinal direction with respect to the inner upper rail portion 20d or the outer upper rail portion 20e of the upper frame 10. have. Fin portions 26b are formed at both opening edges of the swallowing portion 26a, and these are in sliding contact directly with the inner upper rail portion 20d or the outer upper rail portion 20e. In addition, a pulling portion 26c that contacts the intermediate fin portion 12d and pulls the vertical rod 22 toward the indoor side is formed at the outer peripheral side end portion of the swallowing portion 26a.

  FIG. 14 shows a perspective view of the upper anti-vibration component 26. A metal upper end pulling member 27 is integrally attached to the upper anti-vibration component 26. FIG. 15 is a perspective view of the upper end pulling member 27. The upper end pulling member 27 has two side surface portions 27a and 27a along the side wall constituting the swallowing portion 26a of the upper anti-vibration component 26, and the outer peripheral ends of the respective side surface portions 27a are respectively expanded toward the end portions. The longitudinally inclined surface portion 27b is configured to be inclined in the direction.

  In FIG. 13, the longitudinally inclined surface portion 27 b of the upper end pulling member 27 is represented by a broken line. As shown in this figure, the vertically inclined surface portions 27b are formed on both sides of the swallowing portion 26a, one of which is inclined from the outdoor inner peripheral side to the indoor outer peripheral side, and the vertical frame 12 It faces the intermediate fin portion 12d. The other vertically inclined surface portion 27b does not function because it does not face the intermediate fin portion 12d. However, when it is attached to the inner shroud 2 instead of the outer shoji 3 shown in FIG. Function. That is, by forming the vertically inclined surface portions 27b on the both side surface portions 27a, it is possible to share the parts corresponding to the left and right differences.

  FIG. 16 shows an enlarged cross-sectional view of a sash in plan view of the vertical rod 22 from above in a state where the vertical inclined surface portion 27b of the upper end pulling member 27 functions. This figure shows the state at the time of fire occurrence like FIG. 7, and it is assumed that the upper anti-vibration component 26 is melted and melted off at this time. Since the upper anti-vibration component 26 does not exist and the vertical rod 22 moves to the vertical frame 12 side, the vertical inclined surface portion 27b of the upper end pulling member 27 contacts the indoor side of the intermediate fin portion 12d of the vertical frame 12. The intermediate fin portion 12d is pressed indoors. Thereby, the indoor side surface of the vertical rod 22 is pressed against the air-tight material 12g of the indoor fin portion 12f, and it is possible to prevent a gap from being generated between the vertical rod 22 and the vertical frame 12, and to improve the fire prevention performance. .

  In the present embodiment, by providing the inclined surface member 24 having the vertical inclined surface portion 24b at the intermediate position of the vertical rod 22, and providing the upper end pulling member 27 having the vertical inclined surface portion 27b at the upper end portion of the vertical rod 22, the vertical rod 22 Can be drawn toward the vertical frame 12 at the upper end and the intermediate position, respectively, and the fireproof performance between the vertical rod 22 and the vertical frame 12 can be enhanced.

  Although the embodiment of the present invention has been described above, the application of the present invention is not limited to this embodiment, and can be applied in various ways within the scope of its technical idea. For example, in the present embodiment, the internal and external shojis 2 and 3 are retracted into the frame 1, but either the internal or external shoji 2 or 3 is a single-drawing sash that is fixed to the frame 1. Similarly, the present invention can be applied.
