A reinforcing member 5 is attached to the upper frame 21 . As shown in FIG. 1, the reinforcement member 5 is arranged in the central portion of the upper frame 21 in the longitudinal direction at a position corresponding to the meeting portion 50 of the outer shoji 3 and the inner shoji 4 on the upper frame 21 . As shown in FIGS. 3 and 4 , the reinforcing member 5 is arranged across the indoor-outdoor direction extending plate portion 251 and the upwardly protruding fins 252 of the outdoor metal frame 25 .

As shown in FIGS. 3 and 4, the reinforcing member 5 is formed in a plate shape and has a cross-sectional shape with inclined portions at the corners. The reinforcement member 5 is made of, for example, a metal material. The reinforcing member 5 has a first reinforcing side plate portion 51 , a second reinforcing side plate portion 52 , and a reinforcing side inclined plate portion 53 . The first reinforcing side plate portion 51, the reinforcing side inclined plate portion 53, and the second reinforcing side plate portion 52 are continuously formed in this order from the outdoor side X1 toward the indoor side X2.

As shown in FIG. 3 , the first reinforcement side plate portion 51 is formed in a plate shape having a thickness in the vertical direction and extending in the indoor and outdoor directions. The first reinforcement side plate portion 51 is arranged along the upper surface of the indoor/outdoor direction extending plate portion 251 of the upper frame 21 and fixed to the indoor/outdoor direction extending plate portion 251 by a fastening member 511 such as a screw.

The second reinforcing side plate portion 52 has a thickness in the indoor/outdoor direction (view direction) and is formed in a plate shape extending in the vertical direction. The second reinforcing side plate portion 52 is fastened together with the upward projecting fins 252 of the upper frame 21 to the surface 11a of the frame 11 on the exterior side X1 by a fastening member 521 such as a screw.

The reinforcing side inclined plate portion 53 connects the first reinforcing side plate portion 51 and the second reinforcing side plate portion 52 . The reinforcing side inclined plate portion 53 extends while being inclined with respect to the first reinforcing side plate portion 51 and the second reinforcing side plate portion 52 . In this embodiment, the reinforcing-side inclined plate portion 53 is directed from the lower side to the upper side (the outer side in the viewing direction, the side away from the outer shoji 3 and the inner shoji 4) as it goes from the outdoor side X1 to the indoor side X2. incline.

The end portion of the reinforcing side inclined plate portion 53 on the outdoor side X1 is a portion bent at the bent portion 501 (connection portion) and is connected to the end portion of the first reinforcing side plate portion 51 on the indoor side X2. The bent portion 501 of the reinforcing side inclined plate portion 53 and the first reinforcing side plate portion 51 is positioned between the position where the upward projecting fin 252 of the upper frame 21 is formed and the outdoor side rail 211 of the upper frame 21 in the indoor and outdoor direction. is formed between

In this embodiment, the position of the bent portion 501 in the indoor/outdoor direction is, for example, between the position where the upward projecting fin 252 of the upper frame 21 is formed and the position where the outdoor rail 211 of the upper frame 21 is formed. It is arranged slightly on the indoor side X2 from the position where the outdoor side rail 211 of the upper frame 21 is formed. As a result, the outdoor exterior material 13 is formed on the outdoor side X1 from the bent portion 510, and the portion from the bent portion 501 of the reinforcing member 5 to the reinforcing side inclined plate portion 53 can be arranged on the inner side of the outdoor exterior material 13. . Therefore, by forming the outdoor-side exterior material 13 on the outdoor side X1 of the bent portion 510, the reinforcing-side inclined plate portion 53 of the reinforcing member 5 is not visible from the outdoor side X1, thereby suppressing deterioration in design.

The angle formed by the reinforcing side inclined plate portion 53 and the first reinforcing side plate portion 51 is the first angle θ1. The first angle θ1 is an obtuse angle. By forming the first angle θ1 at an obtuse angle (90°<θ1<180°), when a force acts on the upper frame 21 from below, the reinforcement is more effective than when the first angle θ1 is 90°. The material 5 can be bent to a lesser degree at the bent portion 501 .

The indoor-side X<b>2 end of the reinforcement-side inclined plate portion 53 is a portion bent at the bent portion 502 and connected to the lower end portion of the second reinforcement-side plate portion 52 . The bent portion 502 of the reinforcing-side inclined plate portion 53 and the second reinforcing-side plate portion 52 is positioned between the position where the outdoor side rail 211 is arranged and the position where the indoor side rail 212 is arranged in the indoor/outdoor direction. placed in

The angle formed by the reinforcing side inclined plate portion 53 and the second reinforcing side plate portion 52 is the second angle θ2. The second angle θ2 is an obtuse angle. By forming the second angle θ2 at an obtuse angle (90°<θ1<180°), when a force acts on the upper frame 21 from below, the reinforcement is more effective than when the second angle θ2 is 90°. The extent to which the material 5 is bent at the bent portion 502 can be reduced.

Since the reinforcing member 5 configured as described above has the reinforcing-side inclined plate portion 53, the first angle θ1 formed between the reinforcing-side inclined plate portion 53 and the first reinforcing side plate portion 51 and the reinforcing-side inclined plate portion 53 and the second reinforcing side plate portion 52 are both obtuse angles. Therefore, when force acts on the upper frame 21 from below, the reinforcing member 5 of the present disclosure is less likely to bend upward than an L-shaped reinforcing member with 90° corners.

Thus, by forming the reinforcing-side inclined plate portion 53 in the reinforcing member 5, the reinforcing member 5 of the present disclosure is positioned below the upper frame 21 with respect to the L-shaped reinforcing member with the corner of the bent portion of 90°. Strength can be increased when force acts from the side. Therefore, by forming the reinforcing-side inclined plate portion 53 on the reinforcing member 5, even if the length of the upper frame 21 in the longitudinal direction is shorter than the length of the L-shaped reinforcing member with the 90° corner of the bent portion, , a strength equivalent to that of an L-shaped reinforcing member with 90° corners of the bent portion can be ensured. Therefore, the reinforcing member 5 provided with the reinforcing-side inclined plate portion 53 can form the longitudinal length of the upper frame 21 shorter than that of the L-shaped reinforcing member having the corners of the bent portion of 90°.

According to this embodiment, the following effects are obtained. The double sliding window 1 of this embodiment includes a frame 2 having an upper frame 21, an outer shoji 3 and an inner shoji 4 arranged in the frame 2, and a plate connected to the upper frame 21 and reinforcing the upper frame 21. The upper frame 21 includes a first frame side plate portion 251 extending in the indoor and outdoor direction, and a first frame side plate portion 251 connected to the first frame side plate portion 251 and intersecting with the first frame side plate portion 251. A second frame side plate portion 252 that extends in the direction opposite to the side on which the outer shoji 3 and the inner shoji 4 are arranged and is fixed to the frame 11, and the reinforcing member 5 is formed in a plate shape, A first reinforcing side plate portion 51 fixed to the first frame side plate portion 251 , a second reinforcing side plate portion 52 fixed to the second frame side plate portion 252 , the first reinforcing side plate portion 51 and the second reinforcing side plate portion 52 and a reinforcing side inclined plate portion 53 that connects and extends obliquely with respect to the first reinforcing side plate portion 51 and the second reinforcing side plate portion 52 .

By forming the reinforcing-side inclined plate portion 53 on the reinforcing member 5 while securing the strength for reinforcing the upper frame 21, the bent portion is bent upwardly from the L-shaped reinforcing member with 90° corners. The longitudinal length of the frame 21 can be shortened and compact. Therefore, while securing the strength for reinforcing the upper frame 21 with the reinforcing member 5, the manufacturing cost can be reduced by forming the reinforcing member 5 compactly to reduce the materials used and downsizing the manufacturing equipment.

In the present embodiment, the bent portion 501 of the first reinforcement side plate portion 51 and the reinforcement side inclined plate portion 53 is positioned between the position where the second frame side plate portion 252 of the upper frame 21 is formed and the room position at the position in the indoor/outdoor direction. It is positioned between the position where the outer rail 211 is formed. As a result, when the outdoor exterior material 13 is provided on the outdoor side X1 of the frame 11, the portion from the bent portion 501 of the reinforcing member 5 to the reinforcing side inclined plate portion 53 is positioned on the inner side of the outdoor exterior material 13 in the indoor and outdoor direction. Therefore, the reinforcing-side inclined plate portion 53 of the reinforcing member 5 is not visible from the outdoor side X1, and deterioration of the design can be suppressed.

In this embodiment, the reinforcing member 5 is arranged in the central portion of the upper frame 21 in the longitudinal direction. As a result, the force acting on the upper frame 21 can be received while the upper frame 21 is reinforced by the reinforcing material 5 at the central portion in the longitudinal direction. Therefore, the reinforcement of the upper frame 21 by the reinforcing member 5 can be stably performed at the central portion of the upper frame 21 in the longitudinal direction.

In this embodiment, the reinforcing member 5 is arranged at a position corresponding to the meeting portion 50 of the outer shoji 3 and the inner shoji 4 in the upper frame 21 . In the meeting part 50 of the outside shoji 3 and the inside shoji 4, when the outside shoji 3 and the inside shoji 4 are closed, the outside joining frame 34 of the outside shoji 3 and the inside joining frame 44 of the inside shoji 4 are , are arranged so as to overlap each other in the indoor-outdoor direction. Therefore, force is likely to act on the upper frame 21 at the meeting portion 50 of the outer shoji 3 and the inner shoji 4 . In such a case, by arranging the reinforcing material 5 at a position corresponding to the meeting part 50 of the outer shoji 3 and the inner shoji 4 in the upper frame 21, the position where the force is likely to act on the upper frame 21 is reinforced. The material 5 can effectively reinforce the upper frame 21 .
