The cap portion 52 extends along the direction in which the longitudinal ridge 33 is seen, and is configured to have a step portion 521 that abuts on the upper end of the longitudinal ridge 33.

[Construction of opening restraints]
Hereinafter, the construction procedure of the opening suppression tool 4A will be described.
First, the opening suppressing tool 4A is assembled. Specifically, the plate spring member 40 is elastically deformed so that the attachment piece 41 and the engagement piece 43 are close to each other, and the leading edge portions 414 and 431 are accommodated in the accommodation space 516 of the holding member 50. Each engagement protrusion 412 is engaged with each engagement hole 515. As a result, the holding piece 511 holds the mounting piece 41 and the holding piece 512 holds the engagement piece 43. Here, a force for restoring the original shape from the elastically deformed state is generated in the plate spring member 40, so the mounting piece 41 is in pressure contact with the holding piece 511 and the engagement piece 43 is in pressure contact with the holding piece 512 Do. Therefore, the engagement between the engagement protrusion 412 and the engagement hole 515 is maintained, and the plate spring member 40 does not come off the holding member 50. Further, the tip end edge portions 414 and 431 abut on the connection piece portion 513, whereby the swing of the plate spring member 40 in the holding state is suppressed. Thus, the opening suppressing tool 4A is assembled.
In the state where the plate spring member 40 is held by the holding member 50, a slight gap is formed between the tip end edge portions 414 and 431. For this reason, the plate spring member 40 is elastically deformed to further move the attachment piece 41 closer to the engagement piece 43 and the engagement projection 412 is extracted from the engagement hole 515, whereby the plate spring member 40 is removed from the holding member 50. It can also be removed.

Next, the opening restraining device 4A is attached to the vertical weir 33. Specifically, the holding piece portion 511 of the holding portion 51 is fitted between the ridge 36A and the thick portion 37 in the longitudinal direction of the vertical bar 33, and the step portion 521 of the cap portion 52 is estimated for the vertical bar 33 It abuts on the upper end of the vertical weir 33 in a state along the direction. Subsequently, the screw 6 is inserted into the mounting hole 411 through the insertion hole 432 and screwed into the screwing hole 371 so that the mounting piece 41 abuts against the projection 36 B and the thick portion 37. Thus, the opening restraining device 4A is attached to the vertical weir 33.
In the attached state of the opening suppressing tool 4A, the cap portion 52 is disposed to cover the corner portion formed by the upper ridge 31 and the vertical ridge 33, and the leading edge portions 414 and 431 of the plate spring member 40 Also placed outside the room.
Thus, the opening suppression tool 4A is constructed. In addition, the opening suppression tool 4B is also constructed in the same procedure as the opening suppression tool 4A.

[Operation of this embodiment]
Hereinafter, the operation at the time of fire of the vertical sliding window 1 according to the present embodiment will be described.
For example, when a fire occurs outside the room, the ambient temperature of the vertical sliding window 1 rises, and when the temperature of the holding member 50 of the opening suppressing tool 4A rises to 200 ° C. to 250 ° C., the holding member 50 softens. Due to this softening, the holding at the holding portion 51 with respect to the tip end edges 414 and 431 of the plate spring member 40 in the non-engaged state is released, and the plate spring member 40 is restored to the original shape as shown in FIG. At this time, the tip end edge 431 of the engagement piece 43 is positioned to face the engagement portion 234 in the expected direction of the vertical frame 23, and becomes engageable. Note that the holding member 50 reaches the melting point, melts, and disappears due to a further temperature rise.
In the case where the shoji 3 moves in the opening direction due to the occurrence of warpage in the shoji 3 due to a further temperature rise, as shown in FIG. 10, the tip edge 431 of the engagement piece 43 engages the engagement portion 234. Engage and prevent the shoji 3 from opening.
Thus, the opening of the shoji 3 at the time of fire is suppressed. In addition, the opening suppression tool 4B also operates in the same manner as the opening suppression tool 4A.

[Effect of this embodiment]
(1) Since the holding member 50 elastically deforms the plate spring member 40 and holds it in the non-engagement state with the engaging portion 234, when the holding member 50 releases the holding of the plate spring member 40 at the time of fire, the plate spring member While 40 is restored, engagement with the engaging portion 234 is possible, and the opening of the shoji 3 is suppressed. Thereby, it is possible to suppress the formation of a large through hole through which a flame or the like passes and the gap between the window frame 2 and the shoji 3 is expanded due to the deformation due to the temperature rise of the shoji 3.
Further, since the plate spring member 40 itself is positioned to be engageable with the engagement portion 234, there is no need to provide a member engageable with the engagement portion 234 in addition to the plate spring member 40, and the number of parts can be reduced. The configuration can be simplified.
(2) Since the holding member 50 has the cap part 52 which covers the corner | angular part of the shoji 3, the opening suppression tools 4A and 4B can be utilized as a resin cap which covers the corner of the shoji 3 at normal times. On the other hand, at the time of a fire, the leaf spring member 40 which is released from the holding by the holding member 50 and restored can be engaged with the engaging portion 234, and the opening of the shoji 3 can be suppressed. Thus, the two functions of the function as the resin cap in normal times and the function of suppressing the opening of the shoji 3 at the time of fire can be exhibited by the opening suppressing tools 4A and 4B.
In addition, there is no need to separately prepare a dedicated part for holding the plate spring member 40 and a cap part for covering the corner of the shoji 3, and the configuration can be simplified and the workability can be improved. Furthermore, the existing equipment can be effectively used by replacing the existing cap parts with the above-described opening suppressing devices 4A and 4B.
(3) In order for the holding member 50 to hold both the leading edge portions 414 and 431 of the mounting piece 41 and the engagement piece 43 separated from the elastically deformable continuous portion 42, for example, the mounting piece 41 and the engagement piece The restoring force of the plate spring member 40 constantly applied to the holding member 50 can be reduced as compared to the case where the holding portion 50 is held at a position closer to the continuous portion 42 than both leading end edge portions 414 and 431 of the portion 43. Can be stabilized.
(4) In the attached state to the shoji 3 of the opening suppressing tool 4A, 4B, the holding portion 51 extends in the direction along the longitudinal ridge 33 (peripheral direction of the shoji 3), and the cap portion 52 The leaf spring member 40 held by the holding portion 51 and screwed to the vertical bar 33 is arranged so as to extend in the direction of view of the arrow 3 and contact with the corner of the door tip side of the shoji 3. The swing is suppressed by the holding member 50. For this reason, it is not necessary to screw the plate spring member 40 by a plurality of screws, and the plate spring member 40 can be screwed so as not to be pivotable by a single screw 6, and the workability can be improved.
Further, since the holding portion 51 is disposed to extend in the longitudinal direction of the longitudinal ridge 33 and the cap portion 52 is disposed to extend in the prospective direction of the shoji 3, the positioning of the holding member 50 with respect to the shoji 3 in two directions crossing each other is accurate Can be done.
(5) Since the insertion hole 432 is formed in the engagement piece 43, even if the engagement piece 43 is positioned outside the attachment piece 41 in the direction of finding the longitudinal ridge 33, the screw 6 through the insertion hole 432 And the mounting piece 41 can be screwed to the longitudinal bar 33, and the workability can be improved.
(6) Since the tip end portions 414 and 431 of the mounting piece 41 and the engaging piece 43 are disposed on the opening direction side of the shoji 3 with respect to the continuous portion 42, in the restored state of the plate spring member 40, the continuous portion The two end portions 42 are spaced apart from each other, and the tip end portions 414 and 431 of the mounting piece 41 and the engaging piece 43 are wider than the continuous part 42. For this reason, when the sash 3 tries to move in the opening direction, the engagement piece portion 43 engages with the engagement portion 234, and a force that is expanded to the vertical frame 23 side is applied, the vertical frame 23 and the vertical It becomes a state of being caught between the hooks 33, and the opening of the shoji 3 can be further reliably suppressed.
(7) The engaging portion 234, which is a portion to which the airtight material 5 is attached, can be configured as a portion that engages with the opening suppressing tool 4, and the configuration can be simplified.

[Modification]
