For this reason, it is possible to provide the iron edge member 28 without impairing the design.

  In addition, an edge member 28 is placed between the lower rails 122 that are adjacent to each other in the prospective direction when the inner shoji 3 and the outer shoji 4 are lowered to restrict further lowering of the inner shoji 3 and the outer shoji 4. Since the restricting member 27 is provided, for example, even if the lower armpit 22 and the door wheel 29 are melted, the inner shoji 3 and the outer shoji 4 placed on the restricting member 27 are not further lowered. For this reason, it is possible to prevent the inner shoji 3 and the outer shoji 4 from falling off the upper rail 112 or falling off.

  Moreover, since the regulating member 27 is provided at a distance in the vertical direction from the regulating member 27 included in the inner and outer shojis 3 and 4, the inner and outer shojis 3 and 4 move along the rails 112 and 122. Do not touch. For this reason, if the inner shoji 3 and the outer shoji 4 are appropriately stored, it can move smoothly.

  Further, in the state in which the inner shroud 3 and the outer shoji 4 are lowered and the edge member 28 is placed on the placement portion 27 a, the edge portion 13 a located on the upper side of the rail reinforcing member 13 of the lower rail 122 is the lower rail 122. Is higher than the outer peripheral edge 28c formed by the edge member 28 provided on the lower rod 22 that accommodates the door, even if the lower rod 22 and the door wheel 29 are melted, the lowered shoji is between the lower rail 122 and the lower rod 22. It is also possible to prevent movement in the prospective direction.

  Further, in a state in which the inner and outer children 3 and 4 are lowered and the edge member 28 is placed, the edge portion 13 a located on the lower side of the rail reinforcing member 13 of the upper rail 112 is an upper portion that accommodates the upper rail 112. Since the edge member 28 provided on the collar 21 is lower than the outer peripheral edge 28c, even if the chassis 20 is melted, the lowered shoji may move between the upper rail 112 and the upper collar 21 in the prospective direction. It is possible to prevent.

  In addition, the inner child 3 and the outer obstacle 4 are lowered at the end in the prospective direction on the placement portion 27a of the regulating member 27 on which the edge member 28 is placed when the inner child 3 and the outer obstacle 4 are lowered. Since the protrusion 27e that sometimes enters between the edge member 28 and the rail 122 is provided, the protrusion 27e, the internal impingement 3 and the external disability 4 are provided when the inner shroud 3 and the external disability child 4 are lowered. The peripheral surface plate portion 28b of the edge member 28 overlaps the prospective direction. For this reason, it is also possible to prevent the fallen inner shoji 3 and outer shoji 4 from moving in the expected direction.

  In addition, since the thermally expandable graphite 32 is provided on the mounting portion 27a, the adjacent inner shoji 3 and the external shoji that the lower armpit 22 and the door wheel 29 are melted by the flame and are lowered onto the mounting portion 27a. Since the thermal expansive graphite 32 expands between the inner impeller 3 and the outer shoji 4, the inner expansive child 3 and the outer impeller 4 are filled with the expanded thermal expansive graphite 32 so that the inner impeller 3 and the outer impeller 4 can move more reliably. It is possible to prevent the flame from penetrating from below and between the inner and outer children 3 and 4.

  Further, since the two lower frame reinforcing members 17 are joined below the lower rail 122 by the restricting members 27 that are bridged above the lower frame reinforcing members 17 provided along the lower rail 122, the lower It is possible to increase the rigidity of the frame 12 and prevent the lower frame 12 from being broken or separated between the two lower frame reinforcing members 17 when the lower frame 12 is melted.

  In the said embodiment, the rail reinforcement member 13, the upper frame reinforcement member 15, the lower frame reinforcement member 17, the bracket 18, the hollow part reinforcement member 25, the heel reinforcement member 26, the control member 27, and the edge member 28 are made of nonflammable iron. However, nonflammable metals such as aluminum and stainless steel may of course be composed of flame retardant materials.

  In the above embodiment, the frame 10 has two rails on the upper and lower sides, and the joinery 1 including the inner shoji 3 and the outer shoji 4 has been described as an example. However, the number of rails or the number of shojis Is not limited to this. In the case where three or more rails and three or more shojis are provided, an edge member is provided at a portion where the shojis adjacent to each other in the prospective direction face each other, and a regulating member is provided therebelow.

  In the above embodiment, the example in which the edge member 28 is provided on the lower heel 22 of the inner limb 3 and the outer limb 4 opposite to each other in the prospective direction, that is, on the outer side of the lower heel has been described. As long as it is outside the recess 22d, it may be provided in the lower collar 22. Further, the edge member 28 of the above embodiment has an L-shaped cross section. However, if the edge member 28 extends to the open end side so as to form a part of the outer peripheral edge of the shoji, it has the peripheral plate portion 28b. It may be a flat plate.

  In the above-described embodiment, the airtight material 31 is provided in the groove-shaped recesses 21d and 22d of the inner and outer obstacles 3 and 4 to be in contact with the inserted lower rail 122 from the indoor side and the outdoor side, respectively. Although the example has been described, the airtight member 31 may be provided only on one of the indoor side or the outdoor side. In this case, it is desirable that the edge member 28 is provided at least on the side where the airtight member 31 is provided and outside the groove-shaped recesses 21d and 22d.

  In the above embodiment, the example in which the edge member 28 is provided in each of the inner and outer children 3 and 4 has been described. Moreover, in the said embodiment, although the edge member 28 demonstrated the example provided in the position where the inner impingement child 3 and the outer imperial child 4 oppose each other in the state which obstruct | occluded the opening 10a, the indoor side of the inner impingement child 3 was demonstrated. It may be provided on the outdoor side of the shoji 4 or may be provided on either the indoor side or the outdoor side.

  In the above-described embodiment, the grooved recesses 21d and 22d of the upper and lower rods 21 and 22 into which the rails are inserted are formed in a rectangular groove shape having wall portions 21e and 22e facing each other and a flat bottom portion, and the rod reinforcing member 26 However, although the example in which the longitudinal section has a U-shape has been described, the shape of the groove-shaped recess and the flange reinforcing member is not limited to this, and the section may be, for example, a U-shape.

  Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention.
