Description

  The present invention relates to an opening device. In detail, it is related with the opening part apparatus which has the outstanding fire prevention performance.

  Conventionally, in a sliding window, when a fire occurs on the outdoor side, there is a risk that flames, flammable gases, etc. enter the indoor through the hollow portion of the firewood and ignite. Therefore, for example, a structure is disclosed in which a hollow member of a vertical gutter is closed by attaching corner members having a heating foam material as a refractory material to the upper and lower ends of the vertical gutter (see, for example, Patent Document 1).

  However, in the sliding window, a handle as a handle at the time of opening / closing operation is attached to an attachment hole formed in the indoor / outside surface of the door toe. Therefore, when the pull handle is made of resin, the pull handle melts in the event of a fire and the indoor and outdoor mounting holes are exposed. As a result, these mounting holes become through holes and flames, flammable gases, etc. enter the room. . Therefore, for example, a structure is disclosed in which the through hole is closed by attaching a metal penetration preventing member in the housing (see, for example, Patent Document 2).

At the same time, the heating foam materials 73 and 73 were attached around the handle attachment holes 241f and 241g on both sides to which the resin handle was attached.
Thereby, even if the resin puller is melted at the time of the occurrence of a fire, the pulling attachment holes 241f and 241g can be closed by the foaming expansion of the heating foam materials 73 and 73. Therefore, according to this embodiment, since it can suppress that the through-hole penetrated indoors and outdoors is formed in the door-end fence 24, the outstanding fire prevention performance is obtained. In addition, since the resin handles are attached to both the indoor side and the outdoor side, it is possible to unify the design with the non-fire opening device while ensuring excellent fire prevention performance.

  It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.

  In the above embodiment, resin pullers are used as the indoor side puller and the outdoor side puller, but the present invention is not limited to this. A similar effect can be obtained if at least one of the indoor side puller and the outdoor side puller is a resin puller.

Further, as described above, in the above embodiment, in the event of a fire, the air introduction holes 242 and 242 in the glass groove 240 of the door toe cage 24 and the screw holes 243 and 245 on the door tip side of the door toe cage 24 are air introduction holes. 244 and the door wheel adjustment hole 246 and the upper and lower end portions of the door toe cage 24 can be closed with heating foam materials 71, 71, 72, 72, 74, 74. Therefore, if a metal handle is attached to the indoor side and outdoor side handle attachment holes, the metal handle can suppress the intrusion of flames, flammable gases, and the like into the room.
Therefore, at least one of the pull handles may be a metal pull handle. In this case, it is not necessary to attach the heating foam materials 73 and 73 around the puller attachment hole. Thereby, since it can suppress the penetration | invasion of the flame, a combustible gas, etc. to an indoor with a metal puller, the outstanding fire prevention performance is obtained. In addition, a resin pull handle can be attached to the other pull handle attachment hole, and in this case, it is possible to unify the design with the non-fire opening device while ensuring excellent fire prevention performance. .
