Description

[Technical Field]

[0001] The present disclosure relates to building materials. [Background technology]

[0002] Conventionally, fire-resistant materials such as heat-foaming materials have been attached to building materials to improve their fire resistance. It is also known that sealing the gap between the shoji screen and the sill is an effective way to improve the fire resistance of building materials.

[0003] For example, in the fittings of Patent Document 1, a heat-foaming material that foams when heated is attached to the sill. In the event of a fire, the heat-foaming material foams toward the shoji screen, sealing the gap between the shoji screen and the sill. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-113065 Summary of the Invention [Problem to be solved by the invention]

[0005] There are also fittings with a so-called flat rail structure, in which the upper surface of the sill is configured to be approximately flat. In fittings with a flat rail structure, attachments are placed on the sides of the rails that guide the shoji screen, thereby suppressing the occurrence of unevenness caused by the rails.

[0006] However, if an attachment is placed on the sill, it may be difficult to attach the heated foam material to the sill. As such, depending on the configuration of the building material, it may be difficult to attach the heated foam material to the sill.

[0007] In order to avoid such difficulties, if the heat-foaming material is attached to the shoji side, there is a concern that the fire prevention performance will be reduced due to the heat-foaming material falling off.

[0008] The present disclosure aims to provide building materials that can improve fire resistance. [Means for solving the problem]

[0009] The building fixture of the present disclosure comprises a bottom frame, a shoji screen having a vertical stile and a bottom stile, a rail attached to the bottom frame to guide the shoji screen, a vibration prevention member attached to the vertical stile, and a heated foam material attached to the vibration prevention member, the vibration prevention member having an insertion hole into which the heated foam material is inserted, and a through hole that opens to the rail side and is continuous with the insertion hole.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. As shown in FIG. 1, a fitting 1 of this embodiment is installed in an opening 101 of a building 100. The fitting 1 is a sliding window, and includes a frame 2 and a plurality of (specifically, two) shoji screens 4, 5. The fitting 1 is a so-called double-panel sliding window. The opening shape of the opening 101 is approximately rectangular.

[0012] In this specification, "visible direction" refers to the direction in which the faces of the face materials 49, 59 of the shoji screens 4, 5 in the fitting 1 placed in the opening 101 extend. "Left-right direction" refers to the horizontal direction in the visible direction, and refers to the left-right direction when the fitting 1 is viewed from inside the room. "Visible direction" refers to the thickness direction of the face materials of the shoji screens 4, 5 (i.e., the depth direction). "Visible direction" also refers to the direction from inside the room to outside.

[0013] The frame body 2 is a frame body provided along the periphery of the opening 101. The frame body 2 is formed in a rectangular frame shape. The frame body 2 is made of aluminum, aluminum-resin composite, or resin shaped material. The frame body 2 has an upper frame 21, a pair of left and right vertical frames 22, and a lower frame 23.

[0014] The upper frame 21 is a long member extending in the left-right direction above the opening 101. Each vertical frame 22 is a long member extending in the up-down direction at both left-right ends of the opening 101. The lower frame 23 is a long member extending in the left-right direction below the opening 101.

[0015] As shown in FIG. 2, the lower frame 23 has an exterior rail 25 extending in the left-right direction, and an interior rail 26 that is spaced apart from the exterior rail 25 on the indoor side and extends in the left-right direction.

[0016] The outdoor rail 25 and the indoor rail 26 each extend across the entire left-right area of the bottom frame 23. The outdoor rail 25 and the indoor rail 26 each protrude upward. The outdoor rail 25 and the indoor rail 26 may be collectively referred to as "rails 25, 26."

[0017] The fitting 1 also has an attachment 3 that is detachably attached to a partial area of the lower frame 23 that is adjacent to the indoor side of either the outdoor rail 25 or the indoor rail 26. The fitting 1 is a fitting with a so-called flat rail structure.

[0018] The attachment 3 is a member that flattens the upper surface of the lower frame 23. The attachment 3 is elongated and extends in the left-right direction. The attachment 3 has a flat upper surface. The attachment 3 has, for example, an elongated member and end parts provided at each end of the elongated member. The elongated member is, for example, a metal shaped member made of aluminum or the like. The end parts are formed of, for example, resin. The end parts have, for example, holes through which fingers can be inserted. A user can attach or detach the attachment 3 by pinching the end parts. The attachment 3 has an inter-rail attachment 31 and an inner attachment 32.

[0019] The inter-rail attachment 31 is detachably attached to the area of the lower frame 23 between the outdoor rail 25 and the indoor rail 26. The indoor attachment 32 is detachably attached to the area of the lower frame 23 adjacent to the indoor rail 26 on the indoor side.

[0020] The multiple shoji screens 4, 5 include an outer shoji screen 4 and an inner shoji screen 5. The outer shoji screen 4 is arranged on an exterior rail 25 so that it can slide left and right. The inner shoji screen 5 is arranged on an interior rail 26 so that it can slide left and right. When the shoji screens 4, 5 are closed, the inner shoji screen 5 is arranged to the right of the outer shoji screen 4.

[0021] The outer shoji screen 4 has a frame body 41 and a face material 49.

[0022] The frame 41 is a component that forms the outer edge of the outer shoji screen 4. The frame 41 is formed in a rectangular frame shape. The frame 41 is made of aluminum, aluminum-resin composite, or resin shaped material. The frame 41 has an upper frame 42, a left vertical frame 43, a right vertical frame 44, and a lower frame 45.

[0023] The upper frame 42 is a long member extending in the left-right direction that forms the upper edge of the outer shoji screen 4. The left vertical frame 43 is a long member extending in the up-down direction that forms the left edge of the outer shoji screen 4. The right vertical frame 44 is a long member extending in the up-down direction that forms the right edge of the outer shoji screen 4. The lower frame 45 is a long member extending in the left-right direction that forms the lower edge of the outer shoji screen 4. The upper frame 42 and the lower frame 45 are sandwiched between the left vertical frame 43 and the right vertical frame 44. The frame body 41 has a so-called vertically-hung structure.

[0024] As shown in FIG. 3, the left vertical frame 43 has an outdoor portion 431 that constitutes the outdoor portion of the left vertical frame 43, and an indoor portion 432 that constitutes the indoor portion of the left vertical frame 43.

[0025] The outdoor portion 431 has a first wall portion 431a extending in the left-right direction, a second wall portion 431b extending from the end of the first wall portion 431a on the stile 45 side toward the indoor side, a third wall portion 431c extending to the right from the middle of the second wall portion 431b in the forward direction, a fourth wall portion 431d extending from the end of the third wall portion 431c on the stile 45 side toward the outdoor side, a fifth wall portion 431e extending from the outdoor end of the fourth wall portion 431d toward the stile 45 side, and a sixth wall portion 431f extending from the end of the fifth wall portion 431e on the stile 45 side toward the indoor side.

[0026] The indoor portion 432 has a first wall portion 432a extending in the left-right direction, a second wall portion 432b extending from the end of the first wall portion 432a on the lower frame 45 side toward the outdoor side, a third wall portion 432c extending from the middle of the second wall portion 432b in the forward direction toward the lower frame 45 side, and a fourth wall portion 432d extending from the end of the third wall portion 432c on the lower frame 45 side toward the outdoor side.

[0027] The second wall portion 432b of the outdoor portion 431 and the second wall portion 432b of the indoor portion 432 face each other with a gap in the front direction. The sixth wall portion 432f of the outdoor portion 431 and the fourth wall portion 432d of the indoor portion 432 face each other with a gap in the front direction.

[0028] A pair of left and right door rollers 46 are provided on the underside of the lower frame 45. Each door roller 46 is disposed on the outdoor rail 25.

[0029] Each inner shoji screen 5 has a frame 51 and a surface material 59.

[0030] The frame 51 is a component that forms the outer edge of the inner shoji screen 5. The frame 51 is formed in a rectangular frame shape. The frame 51 is made of aluminum, aluminum-resin composite, or resin shaped material. The frame 51 has an upper frame 52, a left vertical frame 53, a right vertical frame 54, and a lower frame 55.

[0031] The upper frame 52 is a long member extending in the left-right direction that forms the upper edge of the inner shoji screen 5. The left vertical frame 53 is a long member extending in the up-down direction that forms the left edge of the inner shoji screen 5. The right vertical frame 54 is a long member extending in the up-down direction that forms the right edge of the inner shoji screen 5. The lower frame 55 is a long member extending in the left-right direction that forms the lower edge of the inner shoji screen 5. The upper frame 52 and the lower frame 55 are sandwiched between the left vertical frame 53 and the right vertical frame 54. The frame body 51 has a so-called vertically-hung structure.

[0032] The right vertical frame 54 is formed generally symmetrically with the left vertical frame 53 in the left-right direction.

[0033] A pair of left and right door rollers 56 are provided on the underside of the lower frame 55. Each door roller 56 is disposed on the indoor rail 26.

[0034] The face material 59 is a rectangular plate material held inside the frame 51. The face material 59 is made of, for example, glass.

[0035] When the shoji screens 4 and 5 are closed, the right vertical frame 44 of the outer shoji screen 4 and the left vertical frame 53 of the inner shoji screen 5 face each other in the forward direction.

[0036] The fitting 1 has a vibration-stopping member 7 attached to the lower end of the left vertical frame 43 of the outer shoji screen 4, and a vibration-stopping member 9 attached to the lower end of the right vertical frame 54 of the inner shoji screen 5. The vibration-stopping member 7 and the vibration-stopping member 9 have a roughly symmetrical structure. The following explanation will use the vibration-stopping member 7 as an example.

[0037] As shown in Figures 3 to 10, the directions in the description of the anti-vibration member 7 are the directions when the anti-vibration member 7 attached to the left vertical frame 43 is viewed from the inside of the room. In the description of the anti-vibration member 7, the right side is the side of the bottom frame 45, and the left side is the side away from the bottom frame 45.

[0038] The anti-vibration member 7 has a bottom portion 71, a restricting portion 72, a first side wall portion 73, and a second side wall portion 74. The anti-vibration member 7 is formed from, for example, a flame-retardant resin.

[0039] The bottom portion 71 has a generally rectangular plate shape with a plate surface extending in the horizontal direction.

[0040] The restricting portion 72 extends downward from the outdoor portion of the lower surface of the bottom portion 71. The restricting portion 72 has a generally rectangular plate shape with a plate surface extending in the finder direction.

[0041] The first side wall 73 extends upward from the upper surface of the bottom 71. The first side wall 73 is provided in a position close to the right end of the bottom 71. The first side wall 73 has a generally rectangular plate shape with a plate surface extending along the projection direction and the up-down direction.

[0042] The second side wall portion 74 extends upward from the upper surface of the bottom portion 71. The second side wall portion 74 is farther away from the lower frame 45 than the first side wall portion 73. The second side wall portion 74 has a bulging portion 74a that protrudes to the left side.

[0043] The anti-vibration member 7 is attached to the left vertical frame 43 with the upper surface of the bottom 71 abutting against the lower surface of the left vertical frame 43. The portion of the anti-vibration member 7 above the bottom 71 is inserted into the left vertical frame 43. The right side of the first side wall 73 abuts against or is close to the left side of the sixth wall 431f of the outdoor section 431 and the left side of the fourth wall 432e of the indoor section 432. The right side of the second side wall 74 abuts against or is close to the left side of the second wall 431b of the outdoor section 431 and the left side of the second wall 431b of the indoor section 432. The left end of the bulge 74a and the left end of the left vertical frame 43 are roughly aligned in the left-right direction. Therefore, when the outer screen 4 is closed, the bulge 74a abuts against or is close to the vertical frame 22.

[0044] The indoor surface of the regulating portion 72 abuts or is close to the outdoor surface of the outdoor rail 25. This makes it possible to prevent the outer shoji screen 4 from rattling.

[0045] Incidentally, in order to enhance fire prevention performance, it is preferable that the fitting 1 be able to suitably close the gaps between the shoji screens 4, 5 and the rails 25, 26 in the event of a fire.

[0046] Therefore, the fitting 1 is provided with a heat-foaming material 6 that is provided in the anti-sway member 7. The heat-foaming material 6 foams when it reaches a predetermined temperature due to a fire or the like, thereby sealing the gap. The heat-foaming material 6 is, for example, in the shape of a rectangular plate. The heat-foaming material 6 includes a heat-foaming material 6A and a heat-foaming material 6B. The anti-sway member 7 has an insertion hole 75 into which the heat-foaming material 6A is inserted, and a through-hole 76 that opens toward the exterior rail 25 and is continuous with the insertion hole 75.

[0047] A cover portion 80 that covers the heat-foamed material 6A is provided on the upper surface of the bottom portion 71. The cover portion 80 has a first cover portion 81, a second cover portion 82, a third cover portion 83, a fourth cover portion 84, and a fifth cover portion 85.

[0048] The first cover portion 81 has an outdoor-side first cover portion 81A and an indoor-side first cover portion 81B. The outdoor-side first cover portion 81A extends upward from the bottom portion 71, with its tip bent toward the indoor side. The outdoor-side first cover portion 81A extends in the left-right direction. The outdoor-side first cover portion 81A is substantially L-shaped when viewed in the left-right direction. The indoor-side first cover portion 81B extends upward from the bottom portion 71, with its tip bent toward the outdoor side. The indoor-side first cover portion 81B extends in the left-right direction. The indoor-side first cover portion 81B is substantially L-shaped when viewed in the left-right direction. The outdoor-side first cover portion 81A and the indoor-side first cover portion 81B are spaced apart.

[0049] The second cover portion 82 has an outdoor-side second cover portion 82A and an indoor-side second cover portion 82B. The outdoor-side second cover portion 82A extends upward from the bottom portion 71. The outdoor-side second cover portion 82A has a rectangular plate shape with a plate surface extending along the front-to-back direction and the vertical direction. The outdoor-side second cover portion 82A is adjacent to the left side of the outdoor-side first cover portion 81A.

The indoor-side second cover portion 82B has a rectangular plate shape with a plate surface extending along the front-to-back direction and the vertical direction. The indoor-side second cover portion 82B is adjacent to the left side of the indoor-side first cover portion 81B. A rectangular cutout is provided at the outdoor-side and lower end of the indoor-side second cover portion 82B. The outdoor second cover portion 82A and the indoor second cover portion 82B are spaced apart from each other.

[0050] The third cover portion 83 has an outdoor-side third cover portion 83A and an indoor-side third cover portion 83B. The outdoor-side third cover portion 83A extends upward from the bottom portion 71. The outdoor-side third cover portion 83A has a rectangular plate shape whose plate surface extends along the projection direction and the vertical direction. The outdoor-side third cover portion 83A is adjacent to the left side of the outdoor-side second cover portion 82A. A rectangular cutout is provided at the indoor-side and lower end of the outdoor-side third cover portion 83A. The indoor-side third cover portion 83B extends upward from the bottom portion 71. The indoor-side third cover portion 83B has a rectangular plate shape whose plate surface extends along the projection direction and the vertical direction. The indoor-side third cover portion 83B is adjacent to the left side of the indoor-side second cover portion 82B. A rectangular cutout is provided at the outdoor-side and lower end of the indoor-side third cover portion 83B. The outdoor third cover portion 83A and the indoor third cover portion 83B are spaced apart from each other.

[0051] The fourth cover portion 84 has an outdoor-side fourth cover portion 84A and an indoor-side fourth cover portion 84B. The outdoor-side fourth cover portion 84A extends upward from the bottom portion 71. The outdoor-side fourth cover portion 84A has a rectangular plate shape whose plate surface extends along the projection direction and the vertical direction. The outdoor-side fourth cover portion 84A is adjacent to the left side of the outdoor-side third cover portion 83A. A rectangular cutout is provided at the indoor-side lower end of the outdoor-side fourth cover portion 84A. The indoor-side fourth cover portion 84B extends upward from the bottom portion 71. The indoor-side fourth cover portion 84B has a rectangular plate shape whose plate surface extends along the projection direction and the vertical direction. The indoor-side fourth cover portion 84B is adjacent to the left side of the indoor-side third cover portion 83B. A rectangular cutout is provided at the outdoor-side lower end of the indoor-side fourth cover portion 84B. The outdoor fourth cover portion 84A and the indoor fourth cover portion 84B are spaced apart from each other.

[0052] The fifth cover portion 85 has an outdoor-side fifth cover portion 85A and an indoor-side fifth cover portion 85B. The outdoor-side fifth cover portion 85A extends upward from the bottom portion 71. The outdoor-side fifth cover portion 85A has a rectangular plate shape whose plate surface extends along the front-to-back direction and the vertical direction. The outdoor-side fifth cover portion 85A is adjacent to the left side of the outdoor-side fourth cover portion 84A and adjacent to the right side of the second side wall portion 74. A rectangular notch is provided at the indoor-side and lower end of the outdoor-side fifth cover portion 85A. The indoor-side fifth cover portion 85B extends upward from the bottom portion 71. The indoor-side fifth cover portion 85B has a rectangular plate shape whose plate surface extends along the front-to-back direction and the vertical direction. The indoor-side fifth cover portion 85B is adjacent to the left side of the indoor-side fourth cover portion 84B and adjacent to the right side of the second side wall portion 74. A rectangular cutout is provided at the outdoor-side lower end of the indoor-side fifth cover portion 85B. The outdoor-side fifth cover portion 85A and the indoor-side fifth cover portion 85B are spaced apart.

[0053] The cover portion 80 is integrally formed. The cover portion 80 and the second side wall portion 74 are integrally formed.

[0054] The left end of the space surrounded by the cover portion 80 and the bottom portion 71 is closed by the second side wall portion 74. The first side wall portion 73 is cut out at a portion that overlaps with the space surrounded by the cover portion 80 and the bottom portion 71 when viewed in the left-right direction. The end of the space surrounded by the cover portion 80 and the bottom portion 71 on the side of the first side wall portion 73 is open. In this way, in the vibration prevention member 7, a hole is formed surrounded by the cover portion 80 and the bottom portion 71.

[0055] The heat-foamed material 6A is inserted into a hole formed by the cover portion 80 and the bottom portion 71 (see FIG. 3). In other words, the anti-vibration member 7 has an insertion hole 75 into which the heat-foamed material 6A can be inserted. The insertion hole 75 is formed by being surrounded by the cover portion 80 and the bottom portion 71.

[0056] An opening that serves as an entrance when inserting the heat-foamed material 6A into the insertion hole 75 is referred to as an "insertion opening 75a." The insertion opening 75a opens on the lower frame 45 side (right side).

[0057] Inside the insertion hole 75, the side closest to the insertion opening 75a is referred to as the "entrance side," and the side away from the insertion opening 75a is referred to as the "rear side." The direction from the entrance side toward the rear side is referred to as the "insertion direction." The heated foaming material 6A can be inserted horizontally into the insertion hole 75; more specifically, the heated foaming material 6A can be inserted to the left. For the anti-vibration member 7 of the left vertical frame 43, the insertion direction is leftward.

[0058] The anti-vibration member 7 also has a through-hole 76 that opens toward the exterior rail 25 and is continuous with the insertion hole 75. The through-hole 76 penetrates the bottom 71 in the vertical direction. Multiple through-holes 76 are provided, specifically four through-holes 76, spaced apart in the left-right direction. Each through-hole 76 has, for example, a slit shape extending in the forward direction. However, the through-hole 76 closest to the insertion opening 75a is formed by cutting out a rectangular edge of the bottom 71 on the insertion opening 75a side. The heated foam material 6A is supported from below by the area between adjacent through-holes 76. Although not shown, each through-hole 76 is located, for example, directly above the exterior rail 25.

[0059] A raised portion 88 is provided inside the insertion hole 75. The raised portion 88 is provided so as to protrude upward from the bottom portion 71. The raised portion 88 is provided on the back side of the insertion hole 75. The raised portion 88 has, for example, a substantially rectangular plate shape with a plate surface extending horizontally. The raised portion 88 extends along the bottom portion 71 and the lower end of the second side wall portion 74.

[0060] Therefore, the portion of the insertion hole 75 that overlaps the raised portion 88 in the vertical direction is smaller in vertical dimension than the portion of the insertion hole 75 that does not overlap the raised portion 88 in the vertical direction. Therefore, the vertical dimension of the back side of the insertion hole 75 is smaller in vertical dimension than the vertical dimension of the entrance side of the insertion hole 75. The heated foam material 6A fits snugly into the portion of the insertion hole 75 that overlaps the raised portion 88 in the vertical direction.

[0061] The upper end of the raised portion 88 on the entrance side forms an inclined surface 88a that slopes downward toward the entrance side. The portion of the insertion hole 75 that overlaps with the inclined surface 88a in the vertical direction has a vertical dimension that decreases toward the back. The portion of the insertion hole 75 that overlaps with the inclined surface 88a in the vertical direction is referred to as the "tapered portion 75b." In other words, the insertion hole 75 has a tapered portion 75b whose vertical dimension decreases toward the back.

[0062] A protrusion 73a that protrudes downward is provided in the cutout portion of the first side wall 73. The protrusion 73a protrudes downward from the first side wall 73. The protrusion 73a has a generally triangular shape that protrudes downward when viewed in the left-right direction. The protrusion 73a is adjacent to the right side of the insertion hole 75. When viewed in the left-right direction, the protrusion 73a overlaps with the insertion hole 75, and more specifically, overlaps with the upper part of the insertion hole 75. Therefore, when the heat-foamed material 6A attempts to move in the opposite direction to the insertion direction, the end of the heat-foamed material 6A on the opposite side to the insertion direction abuts the protrusion 73a. Note that the lower part of the insertion hole 75 does not overlap the protrusion 73a when viewed in the insertion direction. Therefore, the heat-foamed material 6A can be inserted into the insertion hole 75 by passing under the protrusion 73a.

[0063] A cutout portion 74b that is cut out in a rectangular shape in plan view is provided at the outdoor-side end of the second side wall portion 74, which is on the first side wall portion 73 side. The indoor-side end of the cutout portion 74b and the outdoor-side end of the outdoor-side fifth cover portion 85A are aligned in the front-view position.

[0064] The heat-foamable material 6B is provided in the cutout portion 74b. The heat-foamable material 6B is fixed to the cutout portion 74b with, for example, double-sided tape. The heat-foamable material 6B is surrounded by the second side wall portion 74, the outdoor-side fifth cover portion 85A, and the first wall portion 431a and the second wall portion 431b of the outdoor-side portion 431.

[0065] In the event of a fire, the heated foaming material 6B foams and spreads above the second side wall portion 74. The heated foaming material 6B can close the gap between the left vertical frame 43 and the vertical frame 22.

[0066] According to the fitting 1 of this embodiment, the following effects are achieved.

[0067] According to this embodiment, the fitting 1 comprises a vibration-stopping member 7 provided on the left vertical frame 43, and a heated foam material 6A provided on the vibration-stopping member 7. The vibration-stopping member 7 has an insertion hole 75 into which the heated foam material 6A is inserted, and a through-hole 76 that opens on the outdoor rail 25 side and is continuous with the insertion hole 75.

[0068] According to this configuration, in the event of a fire, the heated foaming material 6A foams toward the exterior rail 25 through the through holes 76. Therefore, the gap between the left vertical frame 43 and the exterior rail 25 can be blocked.

[0069] Furthermore, since the heat-foaming material 6A is housed inside the insertion hole 75, it is difficult to see from the outside. This makes it possible to prevent the heat-foaming material 6A from being accidentally removed. Therefore, it is possible to provide a fitting that can improve fire resistance.

[0070] According to this embodiment, the insertion hole 75 opens to the lower frame 45 side.

[0071] According to this configuration, the heat-foamable material 6 is even more difficult to see from the outside, which makes it possible to more effectively prevent the heat-foamable material 6 from being accidentally removed.

[0072] According to this embodiment, the heat-foaming material 6A can be inserted into the insertion hole 75 in the horizontal direction.

[0073] According to this configuration, it is possible to prevent the heat-foamed material 6A from falling off.

[0074] According to this embodiment, the vertical dimension of the insertion hole 75 on the inner side is smaller than the vertical dimension of the insertion hole 75 on the entrance side.

[0075] According to this configuration, by increasing the vertical dimension of the entrance side portion of the insertion hole 75, it is possible to make it easier to insert the heat-foamed material 6A into the insertion hole 75. Furthermore, by decreasing the vertical dimension of the back side of the insertion hole 75, it is possible to fit the heat-foamed material 6A more snugly into the back side of the insertion hole 75. This makes it possible to prevent the heat-foamed material 6A from slipping out of the insertion hole 75. These features make it possible to make the heat-foamed material 6A easier to insert and less likely to slip out.

[0076] According to this embodiment, the insertion hole 75 has a tapered portion 75b whose vertical dimension decreases toward the back side.

[0077] According to this configuration, in a configuration in which the vertical dimension of the back side of the insertion hole 75 is small, the heat-foamed material 6A can be easily inserted to the back side of the insertion hole 75. This makes it even easier to insert the heat-foamed material 6A and more difficult to remove.

[0078] According to this embodiment, if the direction from the entrance side of the insertion hole 75 toward the back side of the insertion hole 75 is defined as the insertion direction, the anti-vibration member 7 has a protrusion 73a that is arranged adjacent to the insertion hole 75 on the opposite side of the insertion direction.

[0079] According to this configuration, the protrusion 73a can prevent the heat-foamed material 6A from moving in the direction opposite to the insertion direction, so that the heat-foamed material 6A can be prevented from slipping out of the insertion hole 75.

[0080] According to this embodiment, the vibration prevention member 7 has a plurality of through holes 76.

[0081] According to this configuration, the heat-foamable material 6A can be efficiently foamed through the plurality of through-holes 76 while the heat-foamable material 6A is supported in the portions between the adjacent through-holes 76.

[0082] Although one embodiment of the fittings of the present disclosure has been described above, the fittings of the present disclosure can be modified as appropriate.

[0083] In the above embodiment, the fitting 1 is a double sliding window, but the number of shoji is not particularly limited. The number of shoji may be, for example, three or four.

[0084] In the above embodiment, the heat-foaming material 6A can be inserted horizontally into the insertion hole 75, but this is not limited thereto. However, in order to suitably prevent the heat-foaming material 6A from being detached, it is preferable that the inlet side and the back side of the insertion hole 75 are aligned in the vertical direction or that the back side is positioned lower than the inlet side.

[0085] In the above embodiment, the fitting 1 is provided with the attachment 3, but the attachment 3 is not an essential component. In other words, the fitting is not limited to a flat rail structure. However, in fittings with a flat rail structure, the attachment limits the attachment of the heat-foaming material to the sill, so it is preferable to use anti-vibration members 7, 9 that allow the heat-foaming material to be attached to the shoji side.

[0086] The configuration of the left vertical frame 43 and the configuration of the upper part of the anti-vibration member 7 are not limited to those of the above embodiment, as long as the anti-vibration member 7 can be attached to the left vertical frame 43.

[0087] In the above embodiment, the insertion hole 75 is formed by being surrounded by the cover portion 80 provided on the upper surface of the bottom portion 71, but the configuration of the insertion hole 75 is not limited to this. For example, the cover portion 80 may be provided on the lower surface side of the bottom portion 71, or may be provided so as to penetrate the bottom portion 71. The configuration of the insertion hole 75 is not particularly limited as long as it allows the heat-foaming material 6A to be suitably inserted therein.

[0088] In the above embodiment, the vertical dimension at the back side of the insertion hole 75 was smaller than the vertical dimension at the entrance side of the insertion hole 75, but such a configuration is not essential as long as it is possible to sufficiently prevent the heated foam material 6A from slipping out of the insertion hole 75.

[0089] In the above embodiment, the insertion hole 75 has a tapered portion 75b in which the vertical dimension becomes smaller toward the back, but such a configuration is not essential as long as it is possible to sufficiently prevent the heated foam material 6A from slipping out of the insertion hole 75.

[0090] In the above embodiment, the anti-vibration member 7 has a protrusion 73a adjacent to the right side of the insertion hole 75, but such a configuration is not essential as long as it is possible to sufficiently prevent the heated foam material 6A from slipping out of the insertion hole 75.

[0091] In the above embodiment, the protrusion 73a has a triangular shape that is convex downward, but the shape of the protrusion is not limited to this. Also, in the above embodiment, the protrusion 73a is convex downward and overlaps with the upper part of the insertion hole 75 when viewed in the insertion direction, but the shape is not limited to this. The protrusion may be convex in the projection direction and overlap with the end portion of the insertion hole in the projection direction when viewed in the insertion direction, or may be convex upward and overlap with the lower part of the insertion hole when viewed in the insertion direction. The shape and position of the protrusion are not limited to those of the above embodiment, as long as they do not hinder the insertion of the heat-foamed material into the insertion hole and can suppress detachment of the heat-foamed material.

[0092] In the above embodiment, the anti-vibration member 7 has the heat-foamed material 6B provided outside the insertion hole 75, but the heat-foamed material 6B is not an essential component.
