For this reason, it is possible to provide the inter-rail reinforcing material 17 with the thermally expandable graphite 14 simply by inserting the thermally expandable graphite 14 into the indoor recess 172c and the outdoor recess 173c, respectively. It is configured to foam to the opened indoor side or outdoor side.

  According to the fitting 1 of the present embodiment, the inter-rail reinforcement member 17 made of aluminum is provided along the inner rail 112 and the outer rail 113 between the inner rail 112 and the outer rail 113 that are adjacent to each other in the prospective direction. Therefore, even if no reinforcing material is provided in the rails 112 and 113, melting of the inner rail 112 and the outer rail 113 can be suppressed when exposed to a flame. In particular, since the inter-rail reinforcement member 17 includes the inner rail facing wall 172 and the outer rail facing wall 173 that face each of the two rails 112 and 113, the rails 17 are exposed to flame from either side of the lower frame 11 in the prospective direction. Even when exposed, the two rail facing walls 172 and 173 can prevent the rails 112 and 113 on the opposite side of the flame from being exposed to the flame.

  Further, since the inter-rail reinforcing member 17 is provided between the inner rail 112 and the outer rail 113, the lower frame 11 can be formed without performing a complicated operation of providing the reinforcing member in the rails 112 and 113. It can be provided only by being placed between the inner rail 112 and the outer rail 113 from above. For this reason, it is possible to provide the joinery 1 having the frame 10 that is less likely to melt the inner rail 112 and the outer rail 113 even when exposed to a flame and is excellent in manufacturability.

  Moreover, since the reinforcement member 17 between rails is lightweight and excellent in workability, it can be equipped with the reinforcement member 17 between rails lightweight and excellent in productivity. Aluminum is more easily melted than iron or the like. However, since the heat-expandable graphite 14 is provided between the inner rail facing wall 172 and the outer rail facing wall 173, it is thermally expandable when heated. When the graphite 14 is foamed, it is possible to suppress melting of the inner rail 112, the outer rail 113, and the inter-rail reinforcing member 17.

  Further, between the inner rail 112 and the inner rail facing wall 172, and between the outer rail 113 and the outer rail facing wall 173, portions located under the shoji 3, 4 in the inner rail 112 and the outer rail 113, respectively. Since the heat-expandable graphite 14 is provided at a position opposite to the inner rail 112 and the outer rail 113, the amount of the heat-expandable graphite 14 is reduced as compared with the case where the heat-expandable graphite 14 is provided over the entire length of the inner rail 112 and the outer rail 113. Is possible. When heated, the thermally expandable graphite 14 foams at least between the shoji 3, 4 and the inner rail 112 and the outer rail 113, and the inner rail 112, the outer rail 113, and the inter-rail reinforcing member 17 Suppresses melting. For this reason, it is possible to efficiently suppress the melting of the inner rail 112, the outer rail 113, and the inter-rail reinforcing member 17 by using the thermally expandable graphite 14.

  In addition, since the inter-rail reinforcement member 17 is provided on both sides of the windshield member 16 in the direction along the inner rail 112 and the outer rail 113, the inner impeller 3 and the outer impeller 4 adjacent to each other in the prospective direction are provided. It is possible to suppress melting of the inner rail 112 and the outer rail 113 while ensuring airtightness under the opposing summing portion. Further, since the heat-expandable graphite 14 is provided between the windshield member 16 made of synthetic resin and the lower frame 11, even if the windscreen member 16 is melted, the heat-expandable graphite 14 expands. Thus, it is possible to prevent the interior and the exterior from being penetrated.

  Further, the upper plate portion 174 connecting the upper end of the inner rail facing wall 172 and the upper end side of the outer rail facing wall 173 of the inter-rail reinforcing member 17 includes the inner shoji 3 as the inner rail 112 and the outer shoji 4 as the outer rail. 113. Since the rails 112 and 113 are melted, for example, when the inner arm 3 and the outer arm 4 are lowered, the inner arm 3 and the outer arm 4 are supported. The shoji 3 and the outer shoji 4 are placed on the upper plate portion 174 of the inter-rail reinforcing member 17, and further lowering of the inner shoji 3 and the outer shoji 4 is restricted. For this reason, after the inner shoji 3 and the outer shoji 4 are placed on the upper plate portion 174, it is possible to prevent further lowering of the inner shoji 3 and the outer shoji 4.

  In addition, when the inner impeller 3 and the outer imperial 4 are placed on the inter-rail reinforcing member 17, the upper projecting pieces 172d and 173d of the inter-rail reinforcing member 17 are inserted into the rail insertion portions 32a and 42a. It is also possible to prevent the movement of the inner and outer children 3 and 4 in the expected direction. In addition, the upper plate portion 174 of the inter-rail reinforcement member 17 is spaced apart from the inner obstacle 3 and the outer obstacle 4 with the inner obstacle 3 and the outer obstacle 4 supported by the inner rail 112 and the outer rail 113. Since the inner rail 112 and the outer rail 113 are supported by the inner rail 112 and the outer rail 113, the inner shoji 3 and the outer shoji 4 can move smoothly without interfering with the upper plate portion 174 of the inter-rail reinforcing member 17. It is.

  In addition, a flame retardant or non-flammable lower frame reinforcing material 13 is provided in the middle lower frame hollow portion 11b provided along the longitudinal direction below the inner rail 112 and the outer rail 113, and between the rails. Since the reinforcing member 17 is connected to the lower frame reinforcing member 13, even if the lower frame 11 is melted, the inter-rail reinforcing member 17 is supported by the lower frame reinforcing member 13, so that the inter-rail reinforcing member 17 falls off. It is maintained between the inner shoji 3 and the outer shoji 4 without. For this reason, it is possible to provide the fitting 1 in which the inner rail 112 and the outer rail 113 are less likely to melt when exposed to a flame.

  In the said embodiment, the example which provided the thermally expansible graphite 14 in the position which opposes the site | part in which the inner shoji 3 and the outer shoji 4 are located on the inner rail 112 and the outer rail 113 in the inter-rail reinforcement material 17 was demonstrated. However, the present invention is not limited to this, and as shown in FIG. 6, the thermally expandable graphite 14 may be provided in the entire region of the inter-rail reinforcing member 17 facing the inner rail 112 and the outer rail 113.

  In the above embodiment, the inter-rail reinforcement member 17 and the lower frame reinforcement member 13 are made of non-flammable aluminum. However, of course, non-flammable metals such as iron and stainless steel are made of flame-retardant materials. You may comprise.

  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 described. Is not limited to this. When three or more rails and three or more shojis are provided, an inter-rail reinforcing material is provided between two rails adjacent in the prospective direction. In addition, one of the inner shoji and the outer shoji is a fitting for a sliding window that is configured to be fixed to the frame body to form a FIX window or a sleeve wall while being supported by a rail to which the shoji is originally guided. It does not matter.

  In the above-described embodiment, the lower frame protrusion is provided between the rails 112 and 113 that are provided on the lower frame 11 and protrude upward and are guided along the longitudinal direction to guide the inner and outer obstacles 3 and 4. Although the example in which the inter-rail reinforcement member 17 is provided has been described, the position at which the lower frame protrusion reinforcement member is provided does not necessarily have to be between the two rails.

  The inner rail facing wall 192 and the lower frame protruding portion opposing wall 193 are arranged at a distance from the opposing inner rail 112 and the upper protruding frame portion 114, respectively. From the upper and lower ends of the part facing wall 193, projecting parts 192 a and 193 a projecting toward the rail 112 or the upper projecting frame part 114 facing each other are provided.

  Opposing pieces 192b projecting to the opposite sides in the vertical direction are provided at the tips of the projecting portions 192a provided at the upper and lower ends of the inner rail facing wall 192, and are provided at the upper and lower ends of the lower frame projecting portion facing wall 193. At the tip of the protruding portion 193a, an opposing piece 193b is provided that protrudes to the opposite sides in the vertical direction. That is, the inner rail facing wall 192 and the upper and lower protrusions 192a are provided with an indoor concave portion 192c that is recessed toward the indoor side and opened toward the indoor side at a portion on the indoor side of the reinforcing member 19 between the lower frame protrusions. An outdoor-side recess 193c that is recessed toward the outside of the room is provided on the outside side of the reinforcing material 19 between the lower-frame protrusions by the frame protrusion facing wall 193 and the upper and lower protrusions 193a.

  A thermally expansive graphite 14 is inserted in a portion extending over the entire length of the indoor side concave portion 192c facing the inner rail 112 of the reinforcement member 19 between the lower frame protrusions provided under the inner impeller 3, and faces the FIX window 6. The thermally expansive graphite 14 is inserted into a portion extending over the entire length of the outdoor recessed portion 193c facing the upper protruding frame portion 114 of the lower frame protruding portion reinforcing member 19 provided at the position.

  In the case of such a single-window window fitting 1, the lower frame protrusion reinforcing member 19 includes an inner rail facing wall 192 and a lower frame protruding wall facing the inner rail 112 and the upper protruding frame 114, respectively. 193, the inner rail located on the opposite side of the flame by the inner rail facing wall 192 and the lower frame protruding portion facing wall 193 even when exposed to the flame from any side of the lower frame 11 in the prospective direction. It is possible to prevent the 112 and the upper protruding frame portion 114 from being exposed to the flame.

  In addition, since the lower frame protruding portion reinforcing material 19 is provided between the inner rail 112 and the upper protruding frame portion 114, the lower frame protruding portion reinforcing member 19 can be attached to the lower frame without performing a complicated operation of providing the reinforcing material in the rail 112. It can be provided only by being placed between the inner rail 112 and the upper protruding frame portion 114 from above the frame 11. For this reason, it is possible to provide the joinery 1 having the frame body 10 that is less likely to melt the inner rail 112 and the upper protruding frame portion 114 even when exposed to a flame and is excellent in manufacturability.
