Description of the invention [Technical field to which the invention pertains] The present invention relates to a double-slot flat-paneled window in which an inner sash and an outer sash are formed in a double-slot flat-pull manner, and in detail, an inner sash And the outer window • The airtight structure of the fan joint. [Prior Art] φ In Patent Document 1, a double-slot flat-panel window in which an inner sash and an outer sash are formed in a double-slot flat-type manner to be mounted on a window frame is disclosed. In the above-mentioned double-slot flat sliding window, the airtight material is used to form an airtight space between the indoor side surface of the inner sash and the window frame, and between the indoor side surface of the outer sash and the window frame, and the airtight material is combined with the airtight material. The inner window sash and the outer window sash form an airtight joint. Further, the first sealing member is attached to the joint position of the sash guide portion in the upper frame of the window frame, and the second sealing member is attached to the upper portion of the inner sash, and the second sealing member and the first sealing structure are attached. The formation of the parts is such that the airtightness is formed between the upper portion of the composite and the upper frame. [Patent Document 1] Japanese Unexamined Japanese Patent Publication No. Hei No. Hei. No. Hei. No. Hei. No. Hei. No. 60-166. [Invention] The above-described conventional double-slot flat-pane window has an inner sash guide portion of the upper frame formed as a groove. A gap is formed in the upper portion of the outer side of the inner window sash, and the remaining upper portion of the joint is inserted into the groove. Therefore, the notched portion of the joint and the one formed as the upper frame groove are sag-6-(2) 1359228 and A gap is formed between the inner side surfaces of the outer window sash, so the second sealing member is used to close the gap to form airtightness. ' However, when the inner sash and the outer sash of the double-slot flat-paneled window are strong and windy, such as a typhoon, the wind pressure will cause the sash to bend toward the indoor side, so the second sealing member will be installed on the inner window. Move toward the indoor side. On the other hand, when the inner sash is opened and closed, the second sealing member slides along the hanging plate. Therefore, the second sealing member overlaps the width of the hanging plate (the amount of elastic deformation of the second sealing member). Small, the sliding resistance generated when the above sliding is made small so as not to increase the force of opening and closing the moving inner sash. Therefore, when the inner sash is bent and deformed as described above, the second sealing member moves toward the room with respect to the upper frame hanging plate, so that the airtightness of the portion is lowered. Further, when the amount of bending deformation of the inner sash is larger than that of the outer sash, the second sealing member moves toward the indoor side with respect to the inner side of the outer sash, so that the airtightness of the portion becomes low. . For example, while the upper part of the inner sash is guided along the upper frame groove, the upper part of the outer sash is a double-slot flat sliding window guided along the upper frame rail, and the inner sash will have large bending deformation due to wind pressure. However, the outer sash is limited by the track, so the bending deformation due to the wind pressure is small. SUMMARY OF THE INVENTION The object of the present invention is to form a double-slot flat-sliding window which, when closed, allows airtightness between the upper portion of the inner sash and the upper frame to form a gap between the inner window sash and the upper frame. The gap between the plate and the outer sash is formed to be sealed and airtight. Even if the inner sash faces the room during strong wind and rain (4) (4) 1359228, the first airtight material is provided with a mounting portion and is disposed at the mounting portion. The downwardly facing airtight portion is attached to the joint position of the inner sash guide groove of the upper frame, so that the airtight portion and the upper combined sliding piece are formed to abut against each other, and the second combined airtight material is formed. The mounting portion and the airtight portion are provided, and the mounting portion is attached to the joint position of the middle hanging plate so that the airtight portion protrudes from the middle hanging plate to the indoor side, the outdoor side, and the lower side, and the airtight portion and the upper portion are combined. The outdoor side surface and the outdoor side upper surface of the sliding sheet are formed to be in contact with each other, and the airtight portion and the outer side surface of the outer sash are formed to abut. In this way, the first combined airtight material and the upper combined sliding piece can form an airtight gap between the inner sash guide groove of the upper frame and the upper upper portion of the inner sash. Since the airtight portion of the second combined airtight material abuts against the outdoor side surface of the upper combined sliding piece and the outdoor side faces, and also abuts against the side of the outer side of the outer sash, the sealing can be surely sealed. The gap between the sash portion of the sash and the center of the sash of the sash and the sash of the sash is indeed airtight. In the present invention, when the combined sliding sheet and the first and second combined airtight members are in the above-described state, the airtight portion of the first combined airtight member may be formed of a plurality of fins. And the fin is placed on the upper surface of the upper combined sliding piece, and the airtight portion of the second combined airtight material is formed by a plurality of fins, and the fin is placed against the first combined airtight material. The fins form a -9 - (5) 1359228 airtight seal between the two, and the fins of the second combined airtight material are respectively extended beyond the middle drop panel to the indoor side, the outdoor side, and the lower side. The outdoor side of the upper combined sliding piece, the upper side of the outer side, and the side of the outer side of the outer sash form abutment. • In this way, since the plurality of fins are formed to be in contact with each other, the airtightness can be surely formed, and the sliding resistance at the time of abutting is small, so that the inner sash can be opened and closed with a small force. In the present invention, the sash portion of the inner sash is guided by the upper slidable sliding sheet to be movable along the inner sash guide groove, and the window sash portion of the inner sash is slid by the upper sash The sheet is guided to be movable along the inner sash guide groove. When the inner sash is at the fully open position, the upper shutter sliding sheet does not abut against the first and second combined airtight members. In this way, the inner sash can be smoothly opened and closed without swinging in the indoor/outer direction. Further, the upper combined sliding piece and the first and second combined airtight members are formed to abut in the fully closed position, and when the sliding is slightly moved from the fully closed position toward the opening direction, the window is formed without being abutted. Since the shutter member does not abut against the first and second airtight members, the inner window sash can be opened and closed with a small force. [Effect of the Invention] According to the present invention, when the inner sash and the outer sash are in the closed state of the fully closed position, the upper combined sliding piece and the first sealed airtight material are formed to be in contact with each other between the upper portion and the upper frame. It can form an airtight, second airtight material -10- 1359228 < (6) It will abut against the upper side of the upper sliding piece and the middle and the outer sash, so that the gap can form a sealing gas. dense. In addition, the overlap width of the second combined airtight material and the upper combined sliding piece is larger than the maximum deformation of the inner sash, so when the strong wind and rain causes the inner sash to bend toward the indoor side, the second combined helium gas The dense material and the upper combined sliding piece are in close contact with each other, so that the airtightness of the above-mentioned gap portion is not lowered. In addition, the second sealing airtight material is attached to the upper frame, and the inner sash is abutting against the upper combined sliding piece when the inner sash is in the fully closed position, and the inner sash is formed so as not to abut when the inner sash is slightly moved in the opening direction. Therefore, the force of opening and closing the moving inner sash is not increased. [Embodiment] [Best Embodiment of the Invention] As shown in Fig. 1, the present embodiment is a double-slot flat-pane window in which the inner sash 2 and the outer sash 3 are attached to the window frame 1 in a double-slot flat-pull manner.

The fins 63 of the second entangled airtight material 60 are formed in contact with the fins 56 of the first conjugated airtight material 50, and are formed to be airtight. When the inner sash 2 having the above-described configuration is in the fully closed position, as shown in FIG. 7, the outdoor side surface 4 3 of the upper combined sliding piece 40 abuts against the fin of the second combined airtight member 60. 63, the fin 63 is elastically deformed. The upper lateral outer airtight material 7 attached to the intermediate hanging plate 14 is abutting against the one end surface in the longitudinal direction of the mounting portion 61 of the second combined airtight material 60, and the upper lateral outer airtight material 7 and the second The combined airtight material 60 (fin 63) is formed continuously. In this way, the airtightness of the upper and vertical corner portions of the indoor side surface of the outer sash 3 can be improved. Next, the opening and closing operation of the inner sash 2 will be described. As shown in Fig. 2, the side portion of the sash 23 of the inner sash 2 is guided by the upper slidable slide 4 成 to move in the longitudinal direction along the sash guide groove 10a - -17-(13) 1359228. For example, the indoor side 0 of the upper combined sliding piece 40 is guided to the inner airtight material 4, and the outdoor hanging plate 14 is guided. As shown in Fig. 8, the window sill of the inner sash 2 is taught with an upper sash slide 70. The upper window slider slide plate 14 is formed to slide, and the window sill of the inner window sash 2 is guided. As shown in Fig. 8(a), the inner sash 2 is an all-inclusive sliding piece 40 and the first combined hermetic sealing material 50, and the material 60 is formed to abut each other. From this state, the inner sash 2 is placed at the beginning of the movement of the inner sash 2 as indicated by the arrow symbol b, such as the sliding piece 40 and the first and second combined airtight members 50, so that the inner sash 2 is required to be moved. The strength is greater. Next, as shown in Fig. 8(b), when the inner sash is combined with the sliding piece 40 and the first and second combined airtight members, the inner sash 2 can be moved to the fully open position with a small force. This fully open position 'is limited by not shown. Next, when the inner sash 2 is in the fully open position, the eighth sliding piece 70 and the first and second combined airtight members 50 do not abut. -18 - δ 42 is along the upper horizontal J plane 4 3 is installed along the upper part of the middle I 22 "70 is the middle and the middle 匡 22 part of the lead-and-close position, the upper second joint 梃 airtight: Moving in the opening direction, the upper upper cymbal 60 will form a contact with the '2 movement until the upper 5 〇, 60 leaves, to the 8th (c) figure of the crescent lock brake (c), the window 60 is the isolation (14) 1359228. In this way, the inner sash 2 can be smoothly opened and closed without swinging in the indoor/outer direction, and can be moved and closed in a small force from the fully closed position to the opening direction. 1.
