JP 2003-253962 A

  The sash frame of the sash as described above is formed of aluminum alloy, resin, etc., and when the sash frame is heated and softened by a fire or the like from the outside of the wall surface, it is softened by heating. May hang down. When the lower frame hangs downward, the shoji supported on the lower frame also moves downward. When the amount of sag is large, the upper arm of the shoji may come off the rail of the upper frame and fall down. For this reason, iron reinforcement is provided at the part of the lower frame where the external shoji is located, or a metal block is provided at the part of the lower frame located below the summoning section to prevent the sliding paper from sliding down. However, there is a problem that the number of members increases, the assembly and construction become complicated, and the cost increases.

  This invention is made | formed in view of this subject, The place made into the objective is to provide the fitting which can prevent the sliding down of a shoji even if it heats.

In order to achieve such an object, a joinery of the present invention includes a frame body that projects from a wall surface that forms an inner / outer boundary of a structure, and a shoji that can be opened and closed above a portion projecting from the wall surface. The first member provided on the door butt portion of the shoji, and the opposing position that is located inside the structure from the shoji and faces the door butt of the shoji with the shoji closed A first member disposed above the second member in a state in which the shoji is closed, and the frame is heated to soften the frame. When the shoji is deformed and moves downward, the first member is engaged with the second member, and the shoji is held by the second member.

  According to such a joinery, the first member provided on the door butt portion of the shoji is disposed above the second member with the shoji closed, so that it projects from the wall surface of the structure and supports the shoji. When the deformed frame body is softened and deformed so as to hang down, the shoji is engaged with the second member as it moves downward. At this time, the second member with which the first member engages is positioned more inside the wall than the shoji in the structure, and thus is more stable than the frame portion where the shoji is supported. For this reason, even if it deform | transforms so that the site | part which the frame overhangs may hang down, it is possible to hold the shoji on the opposing part side.

  In this fitting, it is preferable that the second member has a restricting portion that restricts movement of the engaged first member in the slide opening / closing direction.

  When the frame is heated and deformed, the shoji is also considered to be heated and expand. At this time, if the first member and the second member can freely move relative to each other due to the expansion of the shoji, the first member and the second member may be disengaged due to the relative movement caused by heating. For this reason, even if the heated shoji expands when the second member has a restricting portion that restricts the movement of the engaged first member in the slide opening / closing direction as in the case of the joinery described above, It is possible to prevent the engagement between the first member and the second member from being released.

In such a joinery, the door butt portion and the facing portion have opposite projecting ends extending in opposite directions from each other in the sliding opening and closing direction. comprising respectively extending piece, when closing the sliding door, the provided on the opposing portions opposition direction extending piece is, with respect to the opposite direction extending portion provided on the door tail portion, wherein The first member is provided with a smoke return located on the opposite side of the opposing portion and arranged so that the opposite extension pieces of each other overlap in the prospective direction, and when the shoji is heated, the first member is It is desirable to engage the second member in a state where the opposite-direction extending pieces overlap in the prospective direction.

  According to such a joinery, when the shoji is heated, the first member engages with the second member in a state in which the respective oppositely extending pieces constituting the smoke return overlap in the prospective direction. For this reason, even if it is a case where a shoji is heated and deform | transforms so that it may expand | extend, the state where each opposite direction extension piece of smoke return has overlapped in the prospective direction is maintained. For this reason, even if the shoji is heated, it is possible to more surely prevent a gap from being generated in the door butt side of the shoji.

  In this joinery, it is desirable that the first member is provided on the lower end side of the center in the vertical direction of the shoji.

  When the shoji expands when heated, it extends in an unregulated direction. For this reason, the Tojiri bowl of the shoji supported by the frame extends upward when heated, and the first member provided on the Tojiri bowl moves upward to move the second of the first member. The distance with a member will spread. At this time, the amount of movement by which the Tojiri heel extends and the first member moves increases as the Tojiri heel increases from the lower side (lower frame side) toward the middle of the height direction of the Tojiri heel. Is disposed on the upper end side, the space between the second member and the second member is larger when heated, and the first member and the second member do not engage when the lower frame is softened and droops. There is a fear. For this reason, the amount of movement of the first member when the Tojiri heel is extended by heat by arranging the first member on the lower end side of the Tojiri heel in the vertical direction of the shoji as described above. It can be kept small. For this reason, even if it heats, it is possible to engage a 1st member and a 2nd member more reliably.

  In this joinery, the shoji has a face material and a lower heel that holds a lower end edge of the face material, and the first member is aligned with the lower heel in the slide opening / closing direction. It is desirable that they are arranged.

  According to such a joinery, the first member is arranged at a position aligned with the lower eyelid in the slide opening / closing direction, and therefore moves substantially in the slide opening / closing direction as the lower eyelid extends. On the other hand, the center side in the up-and-down direction of Tojiri may be warped. For this reason, if the first member is provided above the lower heel of the Tojiri heel, the first member may be inclined with respect to the second member due to warpage of the Tojiri heel and may not be easily engaged with the second member. There is. Therefore, the first member and the second member can be more reliably engaged with each other by arranging the first member at a position aligned with the lower eyelid and the slide opening / closing direction.

Further, in a state where the holding member 20 is fixed to the door bottom ridge 38, the edge on the door bottom side of the notch 20d, that is, the edge on the door tip side of the holding fixing portion 20a is cut off from the inner facing protruding piece 38a. They are arranged so that they almost match.

  In the door butt heel 38 of the inner shoji 3, the finding surface on the door tip side from the inner facing protruding piece 38 a is recessed to the opposite side to the outer shoji 4 in the prospective direction than the finding surface on the door butt side of the inner facing protruding piece 38 a. It is. For this reason, the holding fixing portion 20a is fixed so that the holding extension portion 20b and the protruding portion 20c of the holding member 20 protrude to the door end side from the cut out inner facing protruding piece 38a and the inner opposite extending piece 38b. And as shown in FIG. 4, the holding | maintenance extension part 20b and the protrusion part 20c are arrange | positioned at the hollow side. At this time, the holding extension part 20b and the protrusion part 20c are spaced apart from the cut-away inner facing protrusion piece 38a on the door end side portion on the surface facing the door butt ridge 48 of the external shoji 4. Yes.

  When the fitting 1 of the present embodiment is normally attached, the inner shoji 3 and the outer shoji 4 are closed, and the Tojiri heel 38 of the inner shoji 3 and the Tojiri hoe 48 of the outer shoji 4 are opposed to each other. 6. As shown in FIG. 8A, the engaging extension 21b of the engaging member 21 is located above the notch 20d at a position higher than the upper end of the protruding portion 20c of the holding member 20. At this time, the hanging piece 21c is located on the indoor side of the holding member 20, and a notch 20d is located on the outdoor side of the lower end portion of the hanging piece 21c. For this reason, since the engaging member 21 and the holding member 20 do not engage in the state in which the inner impingible child 3 and the outer imperial child 4 are normally attached, the inner impinging child 3 and the outer imperial child 4 slide in the direction of finding. The opening 2a can be freely opened and closed.

  In a state in which the inner impingement child 3 and the outer imperial child 4 are closed, the engaging extension portion 21b of the engaging member 21 is located above the notch portion 20d of the holding member 20, and the smoke return 13 The inner opposite direction extending piece 38b and the outer opposite direction extending piece 48b are disposed so as to overlap each other in the prospective direction.

  When the joinery 1 is heated from the outdoor side due to a fire or the like, the frame body 2 protruding from the outer wall surface S is softened, and the lower frame 2b protruding from the outer wall surface S is lowered by the dead weight of the external shoji 4 Begins to sag. At this time, the external shoji 4 starts to move downward together with the lower frame 2b, and the engaging member 21 provided on the door butt 48 of the external shoji 4 also moves downward. Then, as shown in FIG. 8B, the engaging extension 21 b of the engaging member 21 enters and engages with the notch 20 d of the holding member 20. When the engaging member 21 and the holding member 20 are engaged, the outer panel 4 is supported by the inner panel 3. At this time, in the engaging member 21, the engagement extending portion 21b is restricted from moving in the direction of finding by the holding and fixing portion 20a and the protruding portion 20c. For this reason, in the state in which the engaging member 21 and the holding member 20 are engaged, the state where the inner opposite direction extending piece 38b and the outer opposite direction extending piece 48b overlap in the prospective direction is maintained.

  According to the fitting 1 of the present embodiment, the engaging member 21 provided on the Tojiri 48 of the external shoji 4 is configured so that the internal shoji 3 and the external shoji 4 close the opening 2a. Since the frame 2 projecting from the outer wall surface S is deformed so that the lower frame 2b supporting the outer panel 4 softens and hangs down, the outer panel 4 moves downward. Accordingly, the holding member 20 is engaged. At this time, since the holding member 20 with which the engaging member 21 is engaged is located on the indoor side from the outer panel 4, the holding member 20 is more stable than the part of the lower frame 2 b where the outer panel 4 is supported. For this reason, even if it deform | transforms so that the lower frame 2b which the frame 2 overhangs may hang down, it is possible to hold | maintain the outer shoji 4 with the inner shoji 3. FIG.

  When the frame 2 is heated and deformed, it is conceivable that the outer screen 4 is also heated and expanded. At this time, if the engaging member 21 and the holding member 20 can freely move relative to each other due to the expansion of the outer shoji 4, the engagement between the engaging member 21 and the holding member 20 may be released due to the relative movement caused by heating. is there. For this reason, if the holding member 20 has the protrusion part 20c which controls the movement of the engagement direction of the engagement member 21 to which it was engaged like this embodiment, the heated outer obstacle 4 expanded. However, it is possible to prevent the engagement member 21 and the holding member 20 from being disengaged.

  In addition, the engaging member 21 extends in the opposite direction to the inside edge direction extension piece 38b of the door bottom ridge 38 of the inside edge child 3 constituting the smoke return 13 and the outside edge member 4 when the outside obstacle 4 is heated. The piece 48b is engaged with the holding member 20 in a state where it overlaps in the prospective direction. That is, even if the outer shoji 4 is heated, when the engaging member 21 and the holding member 20 are engaged, the inner opposite direction extending piece 38b and the outer opposite direction extending piece 48b of the smoke flare 13 are provided. Are kept overlapping in the prospective direction. For this reason, even when the external shoji 4 is heated, it is possible to more reliably prevent a gap from being generated between the inner shoji 3 and the door butt collars 38 and 48 of the external shoji 4.

  When the outer shoji 4 expands when heated, each part of the outer shoji 4 extends in an unregulated direction. For this reason, the Tojiri heel 48 of the external shoji 4 supported by the frame 2 extends upward when heated, and the engaging member 21 provided on the Tojiri heel 48 moves upward. As a result, the distance between the engaging member 21 and the holding member 20 increases. At this time, the amount of movement of the engagement member 21 by the extension of the door bottom collar 48 increases from the lower frame 2b toward the middle in the height direction of the door collar, so that the engagement member 21 moves to the upper end side. If it is disposed, the gap between the holding member 20 and the holding member 20 is increased when heated, and the engagement member 21 and the holding member 20 may not be engaged when the lower frame 2b is softened and drooped. is there. For this reason, by disposing the engaging member 21 on the lower end side from the center in the vertical direction of the door bottom collar 48 as in this embodiment, the engagement member 21 when the door bottom collar 48 is extended by heat is used. It is possible to keep the amount of movement small. For this reason, even if heated, the engaging member 21 and the holding member 20 can be more reliably engaged.

  In particular, since the engaging member 21 of the present embodiment is arranged at a position aligned with the lower eyelid 6 in the direction of finding, the engaging member 21 moves substantially in the direction of finding as the lower eyelid 6 extends. On the other hand, the center side in the up-down direction of the Tojiri heel 48 may be warped. For this reason, when the engaging member 21 is provided above the lower heel 6 of the Tojiri rod 48, the engaging member 21 is engaged with the holding member 20 with respect to the holding member 20 due to the warp of the Tojiri rod 48. May become difficult to match. Therefore, the engaging member 21 and the holding member 20 can be more reliably engaged by disposing the engaging member 21 at a position aligned with the lower collar 6 in the direction of finding.

  In the said embodiment, although the shoji holding structure 22 which consists of the engaging member 21 and the holding member 20 was demonstrated, the shape of the engaging member 21 and the holding member 20 is not restricted to the shape mentioned above, The external shoji 4 side The engaging member provided in the upper part may be moved downward and held by the holding member provided on the member supported on the indoor side from the external shoji.

  In the above-described embodiment, the draw-type joinery has been described as an example. However, the present invention is not limited thereto, and a joinery provided with a plurality of sliding door shojis may be used. Moreover, the shoji holding structure 22 may be provided between the Tojiri heel of the shoji which makes a sliding door, and the vertical bone and wall surface which comprise this FIX window facing this Tojiri heel. Further, the sliding direction of the shoji 3, 4 is not limited to the finding direction, and may be the vertical direction.

  In addition, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
