  In the present embodiment, in particular, the engaged piece and the engaging portion are located in the vicinity of the intermediate position in the vertical direction of the wind sampling vertical shaft 413 on the door tip side, and the engaged piece 611, the engaging portion 621, and the engaged portion. Two pairs are provided as a combination of the combined piece 612 and the engaging portion 622, and further, a pair is provided as a combination of the engaged piece 613 and the engaging portion 623 at a position facing the upper end of the wind-extracted vertical shaft 413 on the door end side. It has been.

The interlocking bar 601 is slidably held up and down by a guide rail 602 that is formed over substantially the entire length along the longitudinal direction of the prospective surface 413 s of the wind sampling hoist 413 on the door end side.
An operation mechanism 630 for performing an operation of sliding the interlocking bar 601 up and down is provided on an indoor side surface which is an intermediate position in the vertical direction of the wind sampling hoist 413 on the door end side and intersects the prospective surface 413 s. ing. The operation mechanism 630 transmits the displacement of the operation lever 631 to the rotation lever 632 through an internal displacement transmission mechanism (not shown).

In FIG. 6 (C), a portion of the wind tunnel 413 on the door end side where the operation mechanism 630 is attached is shown in a partial cross-sectional view. As shown in the figure, a part of the outer shell of the operation mechanism 630 constitutes the handle 43 of FIG.
With reference to (A) part and (C) part of FIG. 6, the structure around the interlocking bar 601 of the lock mechanism 600 will be described in further detail.
The guide rail 602 is formed in a shape in which the opening side is slightly narrowed in a sectional view. In such a guide rail 602, a connecting engagement slider 641 as a resin engagement portion that is widened by a step from the opening side of the guide rail 602 toward the back of the opening is slidable along the guide rail 602. Is fitted.
The coupling engagement slider 641 is fixed so as to cover the vicinity of the intermediate position in the vertical direction of the interlocking bar 601. An engagement pin 642 protrudes from the surface of the connection engagement slider 641 opposite to the interlocking bar 601. The engagement pin 642 is slidably engaged with a long hole 633 provided in the rotation lever 632 of the operation mechanism 630.
Engagement sliders 643 having no engagement pins are attached to the upper and lower ends of the interlocking bar 601 by screws.

Particularly in the present embodiment, the engagement slider 643 includes a resin slider portion 643 a that is a resin engagement portion and a metal slider portion 643 b that is a metal engagement portion in the longitudinal direction of the interlocking bar 601. Concatenated. The engagement slider 643 is attached to the interlocking bar 601 by being screwed to the interlocking bar 601 through the resin slider part 643a at a portion where the metal slider part 643b extends to the outer surface of the resin slider part 643a. ing.
The resin slider portion 643a is widened with a step from the opening side of the guide rail 602 toward the inner side of the opening, and engages with the guide rail 602 so as to be slidable without looseness relatively densely.
On the other hand, the metal slider portion 643b has an outer dimension (width dimension, thickness dimension) slightly smaller than that of the resin slider portion 643a, and when the resin slider portion 643a is in contact with the guide rail 602 relatively densely during flattening, A gap is formed between the guide rail 602 and the guide rail 602 is not in direct contact.

For this reason, at the time of flattening, the resin slider portion 643a having a smooth sliding property with the guide rail 602 engages and slides with the guide rail 602, and the movement of the interlocking bar 601 in the guide rail 602 is smooth. is there. In this case, since the metal slider portion 643b has a gap with the guide rail 602, smooth movement is not hindered.
On the other hand, in the case of a fire, the resin slider portion 643a may be melted by heat. In such a case, the metal slider portion 643b engages with the guide rail 602, so that the interlocking bar 601 may drop off. Absent.
In the illustrated embodiment, a metal slider portion 643m is provided at an intermediate portion in the longitudinal direction of the interlocking bar 601. Thereby, the fall prevention force of the interlocking bar 601 at the time of a fire is strengthened.

The operation lever 631 of the operation mechanism 630 rotates clockwise as viewed in part (A) of FIG. When the shoji 40 is closed and this rotation operation is performed on the operation lever 631 and is rotated to a position where the vertical direction is reversed from the illustrated direction, the rotation lever 632 is shown in FIG. 6 (A), it turns counterclockwise, and the tip end side of the turning lever 632 descends. Along with this rotation, the distal end side of the long hole 633 of the rotation lever 632 is lowered, so that the engagement pin 642 and hence the coupling engagement slider 641 is lowered, and the interlocking bar 601 is lowered accordingly.
When the interlocking bar 601 is lowered as described above, the engaged pieces 611, 612, 613 provided on the interlocking bar 601 are lowered and engaged with the corresponding engaging portions 621, 622, 623, The shoji 40 is locked in the closed state.
When the operation lever 631 is rotated in the opposite direction to the above, the corresponding parts are operated in the opposite direction and the lock is released. Part (A) of FIG. 6 shows this unlocked state.

As described above with reference to FIG. 5, in the present embodiment, in particular, the upper end of the interlocking bar 601 is extended to a position where it faces the upper end of the wind sampling hoist 413 on the door end side, and in the vicinity of the extended upper end side. An uppermost engaged piece 613 is provided. Further, an uppermost engaging portion 623 is provided on the expected surface 413 s of the opening vertical frame 53 on the door end side corresponding to the uppermost engaged piece 613.
By engaging the pair of engaged pieces 613 and the engaging portion 623 in the uppermost stage, the warp of the shoji 40 is effectively suppressed even when exposed to a high temperature during a fire.

In this embodiment, in particular, in order to prevent the shoji 40 from being warped by being exposed to a high temperature in the event of a fire, a support that supports the lower end side of the wind-testing vertical shaft 413 on the door-end side that extends downward due to thermal expansion. A member 700 is provided.
Next, the support member 700 will be described with reference to FIGS. 7 and 8.
FIG. 7 is a perspective view around the support member 700 of the vertical window 30a.
FIG. 8 is a cross-sectional view of the vicinity of the support member 700.
7 and 8, corresponding parts to those in FIG. 3 described above are denoted by the same reference numerals, and description thereof will be omitted as appropriate.
The support member 700 has a lower end side expectation surface 413v of the door-end side windage vertical gutter 413 of the opening lower frame 52 in the vertical extension window 30a (as will be described later, a lower end side expectation surface of the door-end side windage lower eaves 412) 412s, but is not located in FIG. 8). The support member 700 includes a support surface portion 701 that is close to and opposed to the lower end side expected surface 413v of the wind sampling downpipe 413 on the door end side.
In the cross-sectional view of FIG. 8, it is avoided that the support member 700 itself is cross-sectioned, and the wind-up downwinder on the door-end side that is continuous in the horizontal direction (the depth direction in the paper of FIG. 8) at the lower end of the wind-up windpipe 413 on the door-end side 412 is viewed in cross-section. For this reason, the lower end side expected surface 413v of the door side wind sampling vertical fence 413 does not appear in FIG. 8, and the lower end side expected side of the door side wind sampling lower arm 412 that is substantially flush with the lower end side expected surface 413v. A surface 412s appears. Accordingly, the lower end side expected surface 412s and the lower end side expected surface 413v have the same height position.

  As easily understood with reference to FIG. 7, the support member 700 includes an attachment surface portion 702 attached along the upper surface of the opening lower frame 52, and toward the one long side of the support surface portion 701 from the attachment surface portion 702. It includes an upright portion 703 that stands vertically and a hanging portion 704 that vertically hangs from the other long side of the support surface portion 701 to a position facing the upper surface of the opening lower frame 52. In the support member 700, the mounting surface portion 702, the upright portion 703, the support surface portion 701, and the hanging portion 704 constitute one metal fitting manufactured by bending a metal plate. The support member 700 is fastened to the upper surface of the opening lower frame 52 by two screws 705 at the attachment surface portion 702.

As described above, the support member 700 described with reference to FIGS. 7 and 8 has the support surface portion 701 in close proximity to the lower end side expected surface 413v of the wind-exposed vertical shaft 413. In FIG. 8, the distance between the lower end side expected surface 412 s and the support surface portion 701 of the wind draft lower rod 412 at the same height as the lower end side expected surface 413 v is represented as d.
This interval d is selected as an interval suitable for supporting the lower end side expected surface 413v of the door-side wind culvert 413 displaced downward due to thermal expansion during a fire by the support surface portion 701, and is set to about 3 mm, for example. The When the lower end side expected surface 413v of the wind-tilt vertical ridge 413 on the front end side is displaced downward and comes into contact with the support surface portion 701, the movement of the lower end side expected surface 413v is firmly restrained by this contact. Therefore, the shoji 40 is effectively prevented from being warped by being exposed to a high temperature during a fire.

As described above, the support member 700 is screwed to the upper surface of the opening lower frame 52 only on the mounting surface portion 702 side, and is perpendicular to the position facing the upper surface of the opening lower frame 52 from the other long side of the support surface portion 701. The lower end side of the drooping portion 704 that hangs down does not reach the upper surface of the opening lower frame 52 and leaves a slight gap.
For this reason, the support surface part 701 of the support member 700 which consists of a plate-shaped metal member as a whole presses and supports the lower end side expected surface 413v of the wind sampling hoist 413 on the door end side with a certain elastic force. Therefore, the restraining force of the positional shift to the lower end side expected surface 413v of the wind-tilt shaft 413 on the door end side by the support surface portion 701 of the support member 700 is further increased. In other words, the displacement force of the lower end side expected surface 413v is strongly regulated by this restraining force, and the warp of the shoji 40 is extremely effectively suppressed.

In the embodiment of the present invention described in detail above, the following operational effects are obtained.
In the present embodiment, in the vertical opening window 30a provided in the opening 30 of the door 1 so as to be openable and closable, the vertical movement is interlocked with the operation of the operation lever 631 along the expected surface 413s of the wind sampling vertical fence 413 on the door tip side. An interlocking bar 601 that can slide in the direction is provided.
Further, the interlocking bar 601 is provided with engagement pieces 611, 612, and 613 that protrude toward the wind-extracting vertical fence 413 on the door end side with an interval in the vertical direction of the interlocking bar 601. Engaging portions 621, 622, and 623 that can be engaged with the engaged pieces 611, 612, and 613 are provided on the prospective surface of the opening vertical frame 53 on the door-end side that faces the door.
As a result, the engaged pieces 611, 612, 613 and the engaging portions 621, 622, 623 engage with each other, so that the warp of the shoji 40 (especially the warp of the upper portion of the shoji 40) is effectively suppressed in the event of a fire. Is done.

Moreover, in this embodiment, the lower end side of the door-end side downspout at the time of a fire in the site | part which opposes the lower end surface of the wind sampling downspout 413 on the door-end side of the opening lower frame 52 which comprises a horizontal frame in the state which the shoji 40 closed. A support member 700 having a support surface portion 701 capable of supporting the expected surface 413v is provided.
Thereby, since the lower end side expectation surface 413v of the door-end side vertical fence is supported by the support surface portion 701 of the support member 700, the warp of the shoji 40 (especially the warp of the lower part of the shoji 40) is effectively suppressed in the event of a fire. .

In the present embodiment, in the vertical extension window 30a, the engagement pieces 611, 612, 613 and the engagement portions 621, 622, 623 are vertically paired with respect to the position of the operation lever 631 (611, 621; 612, 622), and further, a pair (613, 623) is provided on the upper end side of the doorside side fence (winding side fence 413 on the doorside side).
Thereby, the at least one pair of engaged pieces 613 and the engaging portion 623 on the upper end side particularly effectively suppress the warping of the upper portion of the shoji 40 during a fire.

In the present embodiment, in the interlocking bar 601, a resin slider portion 643a that is formed of resin and is slidable by being engaged with a groove formed on a prospective surface 413s of the wind sampling hoist 413 on the door end side, and a metal And a metal slider portion 643b that can be engaged with the groove in the event of a fire.
As a result, the smooth movement is performed smoothly by the resin slider portion 643a, while the metal slider portion 643b withstands heat and escapes the interlocking bar 601 from dropping even in the event of a fire.

  Further, since the vertical opening window 30a is a wind collecting window provided in the door 1, it is possible to collect wind with the vertical opening window 30a while the door 1 is closed during normal life, while fireproofing in the event of a fire. Will also be sufficient.
