In the following description, up, down, left and right represent the up, down, left and right directions in FIG. The type of the sash of the present invention is not limited as long as the shoji slides in the in-plane direction, and examples include a sliding window and a sliding window, but here, as an example, as shown in FIGS. An example of an aluminum sash with a sliding window in which a frame 1 and a shingles 2 and 3 are placed in a sliding manner will be described. The frame 1 is a four-frame framework of an upper frame 1a, a lower frame 1b, and left and right collar frames 1c. On the lower surface side of the upper frame 1a, as shown in FIG. An intermediate piece 41 is provided in the section, a guide rail 42 is provided on the outdoor side of the intermediate piece 41, and an indoor side piece 43 is provided on the indoor side end. On the other hand, as shown in FIG. 14, two parallel rails 4a and 4b are provided on the upper surface side of the lower frame 1b. The inner shoji 2 and the outer shoji 3 are both an upper arm 2a, 3a, a lower arm 2b, 3b, a summon (an inner summon 2c, an outer summon 3c), and a door toe 2d, Panels 2e and 3e are fitted by four-way assembly with 3d. A resin door 31 is attached to the lower side of the lower collars 2b and 3b of the inner and outer children 2 and 3, and the door 31 rolls on the rails 4a and 4b. The upper end portion of the inner shoji 2 is sandwiched between the intermediate piece 41 and the indoor side piece 43 of the upper frame 1a, and the upper end portion of the outer shoji 3 is provided with a groove 3g, and the groove 3g swallows the guide rail 42. Yes. When the inner shoji 2 and the outer shoji 3 are closed, as shown in FIG. 6, the inner summon bowl 2c and the outer summon bowl 3c overlap in the indoor / outdoor direction. A crescent 5 is attached to the center of the sash in the vertical direction. The crescent 5 has a sickle portion (not shown) provided on the inner summit bowl 2c and a receptacle (not shown) provided on the outer summit bowl 3c. The summoning bowl 2c and the outside summoning bowl 3c are bound.

  First, the structure of the opposing surface part of the inner summon bowl 2c and the outer summon bowl 3c will be described in detail.

  The opposing surfaces of the inner summon 2c and the outer summon 3c, that is, the outdoor side 2f of the inner summon 2c and the indoor side 3f of the outer summit 3c are respectively provided with smoke return portions (inner smoke return portion 11, An external smoke return part 12) is provided. As shown in FIGS. 1, 2, and 4, the inner smoke returning portion 11 and the outer smoke returning portion 12 are both substantially L-shaped, and are expected pieces 111 and 121 extending in the indoor and outdoor directions, and the expected pieces 111 and 121. It consists of finding pieces 112 and 122 extending from the tip of each of the shojis in the closing direction of the shoji (rightward direction for the inner shoji 2 and leftward direction for the outer shoji 3). Then, on the indoor side of the tip of the finding piece 112 of the inner smoke returning portion 11 and the outdoor side of the tip of the finding piece 122 of the outer smoke returning portion 12, the finding pieces 112, 122 are oriented in a tapered shape. When the inner shoji 2 and the outer shoji 3 are closed, the inclined surface 113 of the inner smoke return portion 11 and the inclined surface 123 of the outer smoke return portion 12 come into contact with each other, Restrain the summon 2c and the outside summon 3c. A tight material holder 13 is provided at the left end of the outdoor side surface 2f of the inner summit bowl 2c, and a tight material 14 made of non-combustible resin is fitted into the tight material holder 13. The tight material 14 comes into contact with the indoor side surface 3f of the outer summoning cage 3c when the inner shoji 2 and the outer shoji 3 are closed. Moreover, the protrusion piece 15 which protrudes toward the indoor side is provided in the right end of the indoor side surface 3f of the outside summit bowl 3c.

  And the restraining member 16 is attached to the outdoor side surface 2f of the inner summon bowl 2c. The restraining member 16 is made of stainless steel and, as shown in FIG. 3, includes an engagement piece 161 having a substantially rectangular flat plate shape and a base portion 162 having a substantially rectangular parallelepiped shape and positioned at the left end on the indoor side of the engagement piece 161. A screw hole 163 that penetrates the engagement piece 161 and the base portion 162 is formed. When attaching this to the outdoor side surface 2f of the inner summit bowl 2c, as shown in FIGS. 1 and 2, the base portion 162 is inserted into the groove between the expected piece 111 of the inner smoke return portion 11 and the tight material holder 13. Place it in the shape part and fasten it with screws. Then, the engagement piece 161 becomes the direction extended toward the closing direction (right side direction) of the inner impeller 2 from a screwing part. The length of the base 162 in the expected direction is the same as the length in the expected direction of the expected piece 111 of the inner smoke returning portion 11, and the engaging piece 161 abuts on the finding piece 112 of the inner smoke returning portion 11. The length of the engagement piece 161 in the direction of finding is longer than the length of the finding piece 112 in the direction of finding, and the front end of the engaging piece 161 is closer to the closing direction (rightward direction) of the inner limb 2 than the tip of the finding piece 112. Protruding. Note that the engagement piece 161 and the base portion 162 may be separate members or integrally formed.

  On the other hand, the receiving member 17 is attached to the indoor side surface 3f of the outside summit bowl 3c. The receiving member 17 is made of aluminum and has a substantially rectangular parallelepiped shape as shown in FIG. 5, and a recess 171 is formed on the surface (left side surface) on the closing direction side of the outer screen 3. The concave portion 171 has a shape that is dug out leaving the surface on the indoor side, and the vertical width is longer than the vertical width of the engagement piece 161 of the restraining member 16. In addition, screw holes 172 penetrating in the indoor and outdoor directions are formed above and below the recess 171. When this is attached to the indoor side surface 3f of the outside summit bowl 3c, as shown in FIGS. 1 and 4, the receiving member 17 itself is inserted into the groove between the expected piece 121 and the protruding piece 15 of the outer smoke return portion 12. Place it in the shape part and fasten it with screws. In addition, a through-hole 18 that penetrates the sliding element 3 in the sliding direction (left-right direction) is formed in the expectation piece 121 of the outer smoke return portion 12 that is in contact with the receiving member 17. The through-hole 18 is a substantially rectangular recess. The receiving member 17 closes the through hole 18 from the right side.

  As shown in FIG. 7, the restraining member 16 and the receiving member 17 are attached at two positions, that is, an intermediate position between the upper part of the crescent 5 and the sash and an intermediate position between the lower part of the crescent 5 and the sash.

  In such a sash to which the restraining member 16 and the receiving member 17 are attached, when the inner shroud 2 and the outer shoji 3 are closed, the engaging piece 161 of the restraining member 16 penetrates the through hole 18 and the receiving member 17 It is inserted into the recess 171 (state shown in FIG. 1B). Further, when the inner shroud 2 and the outer shoji 3 are opened, the engagement piece 161 is pulled out from the recess 171 and the through hole 18 of the receiving member 17 (state shown in FIG. 1A). Therefore, the restraining member 16 and the receiving member 17 do not affect the opening / closing operation of the inner shroud 2 and the outer shoji 3.

  Then, the engaging piece 161 of the restraining member 16 passes through the through hole 18 and is further inserted into the recess 171 of the receiving member 17, so that the inner summing bowl 2 c and the outer summing bowl 3 c are restrained in the indoor and outdoor directions. Is done. At this time, no special operation is required other than the normal closing operation of the shoji, and the structure itself is very simple. Then, the engagement piece 161 has the through hole 18 and the receiving member 17 corresponding to the length obtained by combining the thickness in the left-right direction of the expectation piece 121 of the outer smoke return portion 12 and the depth in the left-right direction of the recess 171 of the receiving member 17. Since the engagement is deep, the allowance is deep, and the inner summon bowl 2c and the outer summon bowl 3c are surely restrained. Therefore, even if the sash is exposed to flame heat in the event of a fire and the summon ridge is stretched or twisted, it is possible to suppress the deformation of the summon ridge and create gaps, and maintain the sash performance. . Further, the restraining member 16 and the receiving member 17 are attached to the intermediate positions of the upper and lower ends of the crescent 5 and the sash, and the inner summon bowl 2c and the outer summoning are both used by both the crescent 5 and the restraining member 16 and the receiving member 17. Since the joint 3c is restrained, the generation of the gap can be suppressed more reliably. Furthermore, since the through hole 18 formed in the outer smoke return portion 12 is blocked by the receiving member 17, the airtightness and watertightness of this portion are maintained.

  In addition, about the structure of the opposing surface part of an inner summon bowl and an outer summon bowl, it is not limited to said embodiment. For example, contrary to the above-described embodiment, a through hole may be provided in the inner summit and the receiving member attached, and a restraining member attached to the outer summit. Further, any number of restraining members and receiving members may be attached to one sash. For example, only one can be attached to a sash having a low height, or three or more can be attached to a sash having a higher height, depending on the shape of the sash. Furthermore, this configuration can also be applied to a one-way sash in which one of the inner and outer shojis is fitted and killed.

  Second, the configuration of the upper and lower end portions of the inner summon bowl 2c and the outer summon bowl 3c will be described in detail.

  First, as shown in FIG. 8, a circular screw hole 22 is formed at the upper end portion of the expected surface of the inner summon bowl 2 c of the inner shoji 2. The screw hole 22 is a hole into which a screw and a screwdriver are inserted when the upper collar 2a is coupled to the inner summit collar 2c. Then, the aluminum blocking plate 21 is screwed so as to close the screw hole 22. The shielding plate 21 is substantially rectangular and has a shape in which an upper part on the outdoor side is cut out. The shield plate 21 is formed with screw holes 212 at two upper and lower portions. The screw holes 212 are long and long holes so that the vertical position of the shield plate 21 can be adjusted. The upper end portion of the blocking plate 21 protrudes above the upper end of the inner summit bowl 2 c and is located between the intermediate piece 41 and the indoor side piece 43 of the upper frame 1 a. Further, the surface of the blocking plate 21 that is in contact with the inner sump 2c is thinned by cutting the upper part, and a flame-retardant silicon sheet having the same thickness as that of the thinned portion is attached. The sheet protrudes from the upper side, the indoor side, and the outdoor side of the blocking plate 21, and the protruding part is a fin piece 211. In addition, an upper facing member 23 made of aluminum is attached to a position of the upper frame 1a facing the inner summon bowl 2c when the shoji is closed. As shown in FIG. 10, the upper facing member 23 has a substantially L shape composed of an upper facing piece 231 and an indoor facing piece 232, and a screw hole 233 is formed in the upper facing piece 231, and the upper frame Screwed between the intermediate piece 41 and the indoor side piece 43 of 1a. The fin pieces 211 are in sliding contact with the upper facing piece 231 on the upper side, are in sliding contact with the indoor facing piece 232 on the indoor side, and are in sliding contact with the intermediate piece 41 on the outdoor side.

  On the other hand, a long oval screw hole 22 is formed vertically at the lower end portion of the prospective surface of the inner summon bowl 2c of the inner shoji 2 as shown in FIG. The screw hole 22 is a hole for inserting a screw and a screwdriver when the lower rod 2b is connected to the inner summit rod 2c. Then, the aluminum blocking plate 21 is screwed so as to close the screw hole 22. The blocking plate 21 is substantially rectangular and has a shape cut out so as to straddle the indoor rail 4a. The shield plate 21 is formed with screw holes 212 at two upper and lower portions. The screw holes 212 are long and long holes so that the vertical position of the shield plate 21 can be adjusted. The lower end portion of the blocking plate 21 protrudes below the lower end of the inner summit bowl 2c. Further, the surface of the blocking plate 21 on the side in contact with the inner sump 2c is thinned by cutting the lower part, and a flame retardant silicon sheet having the same thickness as that of the thinned portion is attached. This sheet protrudes from the lower side and the outdoor side of the blocking plate 21, and the protruding part is a fin piece 211. In addition, a lower facing member made of aluminum is attached to a position of the lower frame 1b facing the inner summit bowl 2c when the shoji is closed. The lower facing member is composed of two members, an inner lower facing member 24 and an outer lower facing member 25, and as shown in FIG. Inclined surfaces 241 and 251 that are inclined upward are formed, and screw holes 242 and 252 that penetrate vertically are formed. The inner lower opposing member 24 is screwed to the inner peripheral side surface of the indoor lower frame 1b of the indoor rail 4a, and the outer lower opposing member 25 is horizontally arranged from the outdoor side of the indoor rail 4a. Screwed to the upper surface of the extending horizontal piece 35. The fin piece 211 is in sliding contact with the inner lower facing member 24 and the outer lower facing member 25 on the lower side, and is in sliding contact with the external shoji 3 on the outdoor side.

  By providing the blocking plate 21 in this manner, the fin pieces 211 come into contact with the upper frame 1a and the lower frame 1b, and the gap between the frame body 1 and the upper and lower ends of the inner sump 2c is closed, so that the wind can enter. Prevent sound leaks and water inflows. Thereby, it becomes unnecessary to provide resin parts, such as a wind-stop board and a water stop board, in the frame 1, and there is no fear of the fire spread resulting from those melt | dissolving. Moreover, the resin cap becomes unnecessary by closing the screw hole 22 of the inner summit bowl 2c with the blocking plate 21. And the shielding plate 21 prevents a flame and combustible gas from flowing through the screw hole 22 from the inside of the soot to the room, or vice versa, and spreading. Furthermore, by providing the upper facing member 23 and the lower facing member (the inner lower facing member 24 and the outer lower facing member 25) on the frame body 1 side, the gap between the blocking plate 21 is reduced, While minimizing the amount of resin-made fin pieces 211, the interior and the exterior are surely shut off to improve airtightness and watertightness. In addition, about the inner lower side opposing member 24 and the outer lower side opposing member 25, since the inclined surfaces 241 and 251 which incline upward toward the closing direction of the inner sward 2 are formed in the upper surface, the fin piece 211 is smooth. Slid in contact. Further, the blocking plate 21, the upper facing member 23, the inner lower facing member 24 and the outer lower facing member 25 are all made of aluminum, and are the same material as the collars and the frame 1 of the inner shoji 2 and the outer shoji 3. Therefore, the appearance is uniform and the design is good.

  And the screw hole 22 is formed also in the upper and lower ends of the prospective surface of the outer summon 3c of the external shoji 3. The screw hole 22 at the upper end is a circular shape as shown in FIG. 12, and the screw hole 22 at the lower end is a long oval shape as shown in FIG. Then, an aluminum closing plate 26 is screwed to each of the upper and lower ends of the prospective surface of the outer summit bowl 3c so as to close these screw holes 22. Each of the blocking plates 26 is substantially rectangular and has screw holes at two locations, upper and lower. The blocking plate 26 does not protrude from the upper and lower ends of the outer summit bowl 3c unlike the blocking plate, and only blocks the screw hole 22. By closing the screw hole 22 of the outer summon bowl 3c with such a closing plate 26, a resin cap becomes unnecessary. And the obstruction | occlusion board 26 prevents a flame and combustible gas from flowing through the screw hole 22 from the inside of a soot to the room | chamber interior, or the reverse, and spreading.

  In addition, about the structure of the upper-lower end part of an inner summon bowl and an outer summon bowl, it is not limited to said embodiment. For example, the shape of the blocking plate can be freely set according to the shape of the frame. Further, the upper facing member and the lower facing member are not necessarily required, and the fin pieces may be brought into sliding contact directly with the inner peripheral side surface of the frame. Further, the blocking plates may be provided not only at the upper and lower ends of the inner summon but also at the upper and lower ends of the outer summon and the upper and lower ends of the door toe.

  Third, the configuration of the lower frame 1b and the lower collars 2b and 3b will be described in detail.

  As shown in FIG. 14, the lower frame 1b includes an indoor side piece 34 provided at the indoor side end, and a horizontal piece 35 extending horizontally from the outdoor side of the indoor rail 4a. The tight material 33 made of non-combustible resin is provided on the outdoor side surface of this and the outdoor side end surface of the horizontal piece 35. The tight material 33 is in sliding contact with the indoor side surfaces of the lower collars 2b and 3b of the inner and outer shojis 2 and 3, respectively. In addition, the lower collars 2b and 3b of the inner shoji 2 and the outer shoji 3 have grooves 2h and 3h that open downward, and partition surfaces 2i and 3i are provided at the middle portions in the vertical direction of the grooves 2h and 3h. A hole is formed in the partition surfaces 2i and 3i, and a door wheel 31 is placed in the hole. As shown in FIG. 7, the door pulley 31 is provided at each of the left and right ends of the inner shoji 2 and the outer shoji 3.

  And the attracting member 32 is attached to the lower surface side of the partition surfaces 2i and 3i. As shown in FIG. 15, the attracting member 32 has a substantially L shape having an installation surface 322 that abuts against the partition surfaces 2 i and 3 i and a hanging surface 323 extending downward from the installation surface 322. A screw hole 324 is formed in the installation surface 322 and is screwed to the partition surfaces 2i and 3i. The hanging surface 323 is a surface parallel to the expected direction, and the lower end of the hanging surface 323 is inclined downward toward the indoor side, and the lower end surface facing the rails 4a and 4b is an inclined surface portion 321. . The attracting member 32 is attached to each of the central part and both end parts (inner side of the door wheel 31) of the inner and outer children 2 and 3 in the left-right direction. In addition, since the inclined surface part 321 is located above the lower end part (point which contacts the rails 4a and 4b) of the door wheel 31, the attracting member 32 is normal (state of Fig.16 (a)). It does not affect the operation of the inner shoji 2 and the outer shoji 3.

  In the sash provided with such a pulling member 32, when the door wheel 31 is melted in the event of a fire (the state of FIG. 16B), the inclined surface portion 321 of the pulling member 32 comes into contact with the rails 4a and 4b, The inner shoji 2 and the outer shoji 3 are prevented from moving downward. Since the inclined surface portion 321 is inclined downward toward the indoor side, the lower collars 2b and 3b are guided by the inclined surface portion 321 and drawn toward the indoor side. Then, the indoor side surfaces of the lower rods 2b and 3b are in close contact with the tight material 33 provided on the outdoor side surface of the indoor side piece 34 and the outdoor side end surface of the horizontal piece 35 of the lower frame 1b. Thereby, a clearance gap does not arise between the frame 1 and the inner impeller 2 and the outer impeller 3, and it can block | interrupt distribution | circulation of a flame and a combustible gas reliably, and can prevent fire spread. Further, since the tight material 33 is made of non-combustible resin, it does not dissolve and produce a flammable gas.

  In addition, about the structure of a lower frame and a lower collar part, it is not limited to said embodiment. For example, the attracting member only needs to have an inclined surface portion that is inclined downward toward the indoor side, and may be a L-shaped one or a block-shaped one. Further, the inclined surface portion may be curved. Furthermore, the number of attracting members and the left-right position of attachment can be freely set according to the shape and size of the sash, the position of the door wheel, and the like.

  Fourth, the configuration of the upper frame 1a and the upper collars 2a and 3a will be described in detail.

  As shown in FIG. 17, a groove 2g is provided at the upper end portion of the inner impeller 2, and a resin internal anti-spinning member 44 and a metal gap holding member are provided at the upper end portion of the outdoor wall surface of the groove 2g. A tool 45 is provided. As shown in FIG. 20, the inner steady stop member 44 is substantially U-shaped and is attached so as to sandwich the upper end portion of the wall surface on the outdoor side of the groove 2 g, and a portion exposed to the outdoor side of the upper collar 2 a is formed. The facing portion 441 is provided. Since the upper collar 2a is sandwiched between the intermediate piece 41 and the indoor side piece 43 of the upper frame 1a, the facing portion 441 faces the indoor side surface of the intermediate piece 41. As shown in FIG. 7, the internal steadying member 44 is provided at both left and right end portions of the inner limb 2. On the other hand, as shown in FIG. 18, the space | interval holder 45 has a substantially flat plate-like portion exposed to the outdoor side of the upper collar 2a as a sandwiching portion 451, and an upper end portion protrudes indoors. The clamping part 451 has a screw hole 452 that penetrates in the direction of expectation, and is screwed to the upper end of the outdoor side surface of the upper collar 2a. The sandwiching portion 451 of the interval holder 45 also faces the indoor side surface of the intermediate piece 41 in the same manner as the facing portion 441 of the inner steady stop member 44. However, the sandwiching portion 451 has a smaller expected dimension than the facing portion 441. The spacing holder 45 is attached to the central part and both ends (inner side of the inner anti-stabilization member 44) of the inner impeller 2 in the left-right direction. A tight material 48 made of incombustible resin is attached to the lower end of the outdoor side surface of the indoor side piece 43 of the upper frame 1a, and the tight material 48 is in sliding contact with the indoor side surface of the upper collar 2a of the inner shoji 2. .

  Further, in the groove 3g at the upper end portion of the external shoji 3, a resin external steadying member 46 and a metal fall prevention tool 47 are provided. As shown in FIG. 20, the anti-sway member 46 is fitted into the groove 3g and has an inner facing portion 461 that faces the inner side surface of the guide rail 42 and an outer facing portion 462 that faces the outer side surface. doing. As shown in FIG. 7, the external steadying member 46 is provided at both left and right end portions of the external shoji 3. On the other hand, as shown in FIG. 19, the fall prevention tool 47 is substantially L-shaped, and includes a support portion 472 that contacts the bottom surface of the groove 3g, and a contact portion 471 that extends upward from the support portion 472. 472 has a screw hole 473 penetrating in the vertical direction, and the support portion 472 is screwed to the bottom surface of the groove 3g. The contact portion 471 of the fall prevention tool 47 faces the indoor side surface of the guide rail 42. However, the contact portion 471 is farther from the indoor side surface of the guide rail 42 than the inner facing portion 461 of the anti-sway member 46. The fall prevention tool 47 is attached to the central part in the left-right direction and both ends (inner side of the external anti-spinning member 46) of the external obstacle 3. A tight material 48 made of incombustible resin is attached to the lower end portion of the outdoor side surface of the intermediate piece 41 of the upper frame 1a, and the tight material 48 is in sliding contact with the indoor side surface of the upper collar 3a of the outer screen 3.

  In the sash configured as described above, the pinching portion 451 of the interval holder 45 of the inner impingement 2 has a smaller expected dimension than the facing portion 441 of the internal anti-stabilizing member 44, so that the normal state (the state in FIG. 16A) ) Does not come into contact with the intermediate piece 41, and the facing portion 441 of the inner stabilization member 44 is in sliding contact with the indoor side surface of the intermediate piece 41. In addition, the contact portion 471 of the fall prevention tool 47 of the external shoji 3 is further away from the inner side surface of the guide rail 42 than the inner facing portion 461 of the anti-sway member 46, so that it is also normally connected to the guide rail 42. The inner facing portion 461 and the outer facing portion 462 of the anti-sway member 46 are in sliding contact with the guide rail 42 without contacting each other. Therefore, at normal times, the resin inner steady member 44 and the outer steady member 46 are in contact with the aluminum upper frame 1a to prevent scratches and loud collision noises. 45 and the fall prevention tool 47 have no influence on the function and operation of the sash at normal times. In the event of a fire (the state shown in FIG. 16B), even if the resin internal anti-spinning member 44 and the external anti-spinning member 46 are melted by being exposed to flame heat, the metal spacing holder 45 and the fall-down member fall down. The preventive tool 47 prevents the rattle 2 and the external shoji 3 from rattling or falling off. That is, when the inner anti-spinning member 44 of the inner shroud 2 is melted, the sandwiching portion 451 of the spacing holder 45 abuts against the inner side surface of the intermediate piece 41 to maintain the spacing between the upper upper collars 2a and 3a. Therefore, the backlash at the time of locking of Crescent 5 is suppressed. In addition, when the anti-sway member 46 of the external shoji 3 is melted, the fall prevention tool 47 comes into contact with the indoor side surface of the guide rail 42 to prevent the external shoji 3 from falling to the outdoor side. Further, since the spacing holder 45 and the fall prevention tool 47 regulate the movement of the upper lids 2a, 3a of the inner and outer children 2 and 3 to the outdoor side, the tight material 48 is applied to the indoor side surfaces of the upper collars 2a, 3a. The contacted state can be maintained. If the movement of the upper eyelids 2a and 3a in the expected direction is restricted in this way, the inner shy child 2 and the outer shingle 3 will not fall off.

  In addition, about the structure of an upper frame and an upper collar part, it is not limited to said embodiment. For example, as long as the inner steady rest member, the spacing holder, the outer steady rest member, and the fall prevention tool satisfy the above-mentioned requirements, any shape or attachment method to the upper eyelid may be used. May be. In addition, the number of the internal anti-sway member, the spacing member, the external anti-spin member, and the fall-preventing device and the horizontal position of the attachment can be freely set according to the shape and size of the sash.

  Fifth, the configuration of the fence frame 1c and the door-end fences 2d and 3d will be described in detail.

  As shown in FIG. 21, vertically extending ridges 51 are formed on the inner peripheral side surface of the collar frame 1 c of the frame body 1. The protrusion 51 is provided at a position facing the expected surface of the shoji door side, and in the right collar frame 1c shown in FIG. 21, it faces the expected surface of the door rod 2d of the inner shoji 2. . As shown in FIG. 6, the left hook frame 1 c is provided with a ridge 51 so as to face the expected surface of the door rod 3 d of the external shoji 3. Hereinafter, the right side frame 1c and the door tip portion of the inner shoji 2 will be described, but the same applies to the left side frame 1c and the shoji 3.

  A groove 2j that squeezes the ridges 51 of the heel frame 1c is formed on the prospective surface of the door ridge 2d of the inner shoji 2. A resin attracting tool 52 (FIG. 23) and a metal stopper 53 (FIG. 21) are provided in the groove 2j. As shown in FIG. 22, the stopper 53 is substantially L-shaped when viewed from above, and has an installation portion 532 that contacts the bottom surface of the groove 2 j and a latch that extends from the indoor side end of the installation portion 532 toward the right side. A surface 531. The locking surface 531 is inclined toward the indoor side toward the right direction (the closing direction of the inner impingement 2), and faces the indoor side surface of the ridge 51 when the inner impingement 2 is closed. In addition, a screw hole 533 that penetrates in the left-right direction is provided in the central portion in the vertical direction of the installation portion 532, and a screw is inserted into the screw hole 533 and screwed to the door-end rod 2d. On the other hand, the attracting tool 52 has substantially the same shape as the anti-slip tool 53, and includes an installation portion 522 and a contact surface 521. The contact surface 521 is in the right direction (the closing direction of the inner shoji 2). It inclines toward the indoor side toward. However, as shown in FIG. 24, the contact surface 521 is located on the outdoor side of the locking surface 531 of the come-off stopper 53. Moreover, it does not have a screw hole and is bonded to the door-end ridge 2d. In addition, as shown in FIG. 7, the attracting tool 52 and the come-off prevention tool 53 are each attached to the door-end fence 2d. Both are attached to the center in the vertical direction of the door toe 2d, and the upper and lower parts, but the upper attracting tool 52 is below the upper detent 53 and the lower attracting tool 52 is It is located above the lower stopper 53. In addition, a refractory material 54 is attached to the bottom surface of the groove 2j of the door toe 2d except for the part to which the attracting tool 52 and the slip-off preventing tool 53 are attached. The refractory material 54 is made of an epoxy-based material, foams at about 200 ° C., and expands in the thickness direction (perpendicular to the mounting surface). Further, the same refractory material 54 is also attached to the surface of the installation portion 532 of the stopper 53. In addition, the indoor side piece 55 is provided in the indoor side end of the collar frame 1c, and the tight material 56 which consists of nonflammable resin is attached to the outdoor side surface of the indoor side piece 55. FIG. When the inner shoji 2 is closed, the tight material 56 comes into contact with the indoor side surface of the door toe 2d.

  In the sash constructed as described above, when the shoji (inner shoji 2 and outer shoji 3) is normally closed from the opened state, the contact surface 521 of the resin-made attracting tool 52 is provided on the frame 1c. The shoji is brought into contact with the ridges 51 and is drawn indoors to prevent rattling, and the tight material 56 is brought into contact with the indoor side surface of the door toe 2d to prevent a gap from being generated. In addition, the resin attracting tool 52 is prevented from coming into contact with the eaves frame 1c, so that it is prevented from being scratched or generating a large collision sound. When the sash is exposed to flame heat in the event of a fire, and the resin attracting tool 52 is melted, the locking surface 531 of the metal stopper 53 is a protrusion of the collar frame 1c in a state where the shoji is closed. 51, it is in contact with the indoor side surface of 51, draws the shoji to the indoor side, and maintains the state in which the tight material 56 is in contact with the door toe 2d, thereby preventing rattling and gaps. And if the movement of the expected direction of the door of a shoji is regulated in this way, the shoji will not come off from the frame 1. In addition, since the contact surface 521 of the attracting tool 52 is located on the outdoor side of the locking surface 531 of the come-off preventing tool 53, the attracting tool 52 is normally in contact with the protrusion 51 of the collar frame 1c. The slip stopper 53 does not contact the protrusion 51. Therefore, the stopper 53 does not affect the function and operation of the sash at normal times. Further, in the event of a fire, the refractory material 54 attached to the door-end fences 2d and 3d foams and comes into contact with the fence frame 1c, so that the gap is more reliably closed.

  In addition, about the structure of a fence frame and a door-end fence part, it is not limited to said embodiment. For example, as long as the attracting tool and the slip-off preventing tool satisfy the above-described requirements, any shape, attachment method to the door-toe, etc. may be used. In addition, the number of attracting tools and anti-separation tools and the vertical position of attachment can be freely set according to the shape and size of the sash.

  As described above, the sash according to the present embodiment includes the opposing surface portion of the inner summon and the outer summon, the upper and lower end portions of the inner summon and the outer summon, the lower frame and the lower frame, the upper frame, A structure for preventing gaps between the shojis or between the shojis and the frame body at the time of a fire is provided in each part of the upper eaves part, eaves frame and door-end eaves part. In other words, in the event of a fire, each flame of the shoji can be stretched and twisted, and resin parts (such as lower armchairs, upper armrests and door toe attractors) ) Will dissolve. At that time, since the inner summon of the inner shoji and the outer summon of the outer shoji are reliably restrained in the indoor and outdoor directions by the crescent and the restraining member, there is no gap between the inner shoji and the outer shoji. Moreover, the drawing member provided in the lower arm prevents the shoji from moving downward, and draws the lower part of the shoji to the indoor side. Furthermore, since the intermediate piece of the upper frame is located between the upper heels of the inner and outer pelvic children, and the distance holder provided on the upper heel of the inner limb is in contact with the intermediate piece, the distance between the upper heels Is held down to prevent backlash in the normal state of the crescent. In addition, the fall prevention tool provided on the upper arm of the external shoji comes into contact with the guide rail of the upper frame, thereby preventing the upper part of the shoji from moving to the outdoor side. In addition, by preventing the downward movement of the shoji by the lower heel pulling member, the upper heel is prevented from coming off from the upper frame, and the interval holder and the fall-preventing device are reliably brought into contact with the upper frame. Furthermore, the door stopper part of the shoji is maintained in the state of being pulled indoors by the detachment stopper provided on the door-toe. The upper frame, the lower frame, and the heel frame are each provided with a tight material made of incombustible resin at a position facing the indoor side surface of each fold of the shoji, and each heel drawn toward the indoor side as described above. In close contact with the tight material, it prevents a gap from being generated with the shoji on the four sides of the frame. The tight material may be any material as long as it is positioned between the shojis of the shoji and the frame, and may be attached to either the shoji or the frame. In addition, since the bishole of the shoji summoning tub is blocked by the blocking plate and the closing plate, it prevents the flame and flammable gas from flowing out of the interior of the tub through the bishole to the inside and outside of the room. As described above, the sash of the present embodiment prevents gaps from occurring at the four rounds of the frame body and the summing part of the inner and outer shoji, and further prevents communication between the interior and the exterior via the interior of the bag. Therefore, it is possible to prevent the spread of fire by reliably blocking the flame and flammable gas.
