JP, 2016-44519, A

  However, the resin sash as described in Patent Document 1 above is exposed to high temperature at the time of fire, and when the door wheel provided on the lower part of the shoji formed of the resin member melts, the shoji on the rail of the lower frame Move down. At this time, a load is applied to the center of gravity of the shoji, and there is a risk that the center of gravity falls and a gap is generated between the shoji and the frame. This gap forms a part that communicates indoors and outdoors, and it is easy to transfer the outside heat to the inside, so it is required to shut off the indoors and outdoors even between the shoji and the frame that moved downward at the time of fire. , There is room for improvement in that regard.

  Then, this invention is made in view of the said situation, and provides a fixture which can shut off indoors and outdoors between a shoji and a frame at the time of a fire.

In order to achieve the above object, the present invention adopts the following means.
That is, the fitting according to the present invention includes a frame configured by framing an upper frame, a lower frame, and left and right vertical frames, and a shoji slideably disposed in the frame, the lower frame being a frame. A rail frame protruding upward and provided along the longitudinal direction of the lower frame, and a metal rail portion extending in the longitudinal direction of the rail frame, the shoji in the vertical direction It is formed in a quadrilateral frame shape having a pair of extending vertical ridges and an upper ridge and a lower ridge extending in the lateral direction, and the lower ridge is a door wheel capable of traveling along the rail portion of the lower frame; A metal anti-falling member extending along the longitudinal direction of the lower frame below the center of gravity of the shoji, and the anti-falling member has a concave groove engageable so as to straddle the rail portion. Are disposed at a position where they do not interfere with the rail portion when the shoji travels on the door wheel Is, and the in the event of a fire door roller is characterized in that said molten sash is provided such that the groove when moving downward to engage the rail section.

In the fixture constructed in this way, when the door wheel of the shoji is melted at the time of fire, the shoji moves downward, and the concave groove of the fall-off preventing member in the state of remaining unmelted metal approaches the rail portion. While engaging with the rail from above. Therefore, it is possible to restrict the downward movement of the shoji until it comes out of the frame, and prevent the shoji from falling outside. And at normal times, the dropout prevention member provided on the lower weir can open and close the shoji without interfering with the rail portion.
Further, in the fitting of the present invention, since the dropout prevention member is disposed below the center of gravity of the shoji, it is possible to prevent the shoji from curving and hanging down at the center of gravity. Therefore, the shoji can be moved downward in a parallel state, and the shoji can be prevented from being inclined in the in-plane direction. Thereby, in a fire, a gap does not occur between the frame and the shoji which has moved downward, and indoor and outdoor can be shut off.

  In the fitting according to the present invention, it is preferable that a heating foam be provided on the upper surface of the fall-off preventing member.

  In a fixture constructed in this manner, the heated foam provided on the upper surface of the fall-off preventing member foams downward in the event of a fire. At this time, the fall-off preventing member is pushed downward by the foamed heating foam material, and is displaced downward by the foamed thickness of the heating foam material. As a result, the shoji can be pushed upward to correspond to the downward displacement of the anti-fall-off member and maintain a position where it does not come off the frame, and the heating foam can delay the time of temperature rise of the anti-fall-off member .

  Further, in the fitting according to the present invention, it is preferable that the drop-off preventing member is formed in a tapered shape in which the groove width gradually increases as the inner side surface forming the recessed groove goes downward from the top.

  In the fitting configured as described above, by making the inner side surface forming the concave groove of the fall-off prevention member tapered, interference with the rail portion of the fall-off prevention member can be reliably prevented under normal conditions. And in a state where the shoji has moved downward, the concave groove can be reliably engaged with the rail portion, and the shoji can be made to be hard to fall down.

Thereby, in a fire, a gap does not occur between the shoji 2 moved downward and the frame 1, and the indoor and outdoor can be shut off.

  Further, in the pulling window 100 of the present embodiment, as shown in FIG. 4, in the event of a fire, the heating foam material F1 provided on the upper surface of the falling prevention member 170 foams downward. At this time, the falling-off preventing member 170 is pushed downward by the foamed heating foam material F1, and is displaced downward by the foamed thickness of the heating foam material F1. As a result, the shoji 2 is pushed back upward corresponding to the downward displacement of the falling-off preventing member 170 and can maintain the position where it does not come off the frame 1, and the time for the temperature rise of the falling-off preventing member 170 by the heating foam material F1. Can be delayed.

  Further, in the present embodiment, by tapering the inner side surface 171 a forming the concave groove 171 of the fall prevention member 170, interference with the rail main body 132 in the fall prevention member 170 can be reliably prevented under normal conditions. Then, in the state where the shoji 2 moves downward, the concave groove 171 can be reliably engaged with the rail main body 132, and the shoji 2 can be made to be hard to fall down.

  As mentioned above, although embodiment of the fixture by this invention was described, this invention is not limited to said embodiment, It can change suitably in the range which does not deviate from the meaning.

  For example, in the embodiment shown above, although the heating foam material F1 is provided on the upper surface of the falling prevention member 170, the heating foam material F1 may be omitted.

  Further, in the present embodiment, as the shape of the falling-off preventing member 170, a tapered shape in which the groove width gradually increases as the inner side surface 171a facing in the indoor / outdoor direction in the recessed groove 171 goes downward from above is formed. It is not limited to being in such a shape. The point is that the concave groove of the fall-off preventing member can be engaged with the rail body 132 (rail portion), and in this engaged state, the shape may be such that the shoji 2 does not come off from the rail portion (lower frame 12) For example, the inner side surface may extend in the vertical direction.

  Moreover, in the embodiment shown above, although the frame 1 and the housing 20 are resin, this invention is not limited to this. A metal member such as aluminum may be provided on at least one of the indoor and outdoor sides of the frame 1 and the housing 20.

  Furthermore, the frame and housing of the present invention are formed of an extrusion-formed member in which an internal space is formed. And the inner space of the frame and the housing is continuous along the longitudinal direction of the frame and the housing.

  In addition, it is possible to replace components in the above-mentioned embodiment with known components as appropriate without departing from the spirit of the present invention.
