An outer wall portion 52c that rises upward from the edge of the outer wall portion 52 and is connected to the indoor side edge of the outdoor flat surface portion 51, and a protrusion 52d that is connected to the flat surface 51a of the outdoor flat surface portion 51 from the upper edge of the outer wall portion 52c and protrudes indoors. have. As shown in FIG. 4, the inner wall portion 52b and the protrusion 52d are not provided at both end portions in the left-right direction, and the portions where the inner wall portion 52b and the protrusion 52d are provided are the inner wall notch portion 52e and the protrusion notch. A portion 52f is formed.

  The inner window 3 includes an inner window frame 30 provided in a rectangular frame 4, two sliding doors 31 that are attached to the inner window frame 30 and can be opened and closed by sliding the inner window frame 30 in the left-right direction, A sliding window with

  Each shoji 31 includes a glass 32 and a rectangular casing 33 that accommodates the peripheral end of the glass 32. The lower rod 33a included in the housing 33 is provided with a rail insertion portion 33b into which a lower rail 34b included in the lower frame 34 constituting the inner window frame 30 is inserted. The rail insertion portion 33b is rotatable. There is provided a door wheel 33c that has wheels and supports the sliding screen 31 so as to be slidable.

  The lower frame 34 includes a lower frame main body 34a housed in the recess 52 of the attachment 5, and two lower rails 34b that protrude upward from the lower frame main body 34a and are provided in parallel in the left-right direction. Have. In the lower rail 34b, when the two shojis 31 are closed, the end that is on the door end side is provided up to the end of the lower frame main body 34a, but the other end is the lower frame main body. A rail cutout 34c is provided without being provided up to the end of 34a.

  The lower frame main body 34a has a main body flat surface portion 34d that is substantially flush with the flat surface 51a of the outdoor flat surface portion 51 when housed in the recess 52, and is located on the indoor side in the prospective direction of the main body flat surface portion 34d. The end portion 34e is configured to be close to the upper edge of the inner wall portion 52b of the attachment 5, and the outdoor side end portion 34f in the expected direction is configured to be close to the tip of the projection 52d of the attachment 5.

  Further, both end portions in the prospective direction of the main body flat portion 34 d have curved extending portions 34 g that are bent while being curved toward each other downward, and the lower ends of the curved extending portions 34 g are attached to the attachment 5. The lower frame 34 is accommodated in the recess 52 in contact with the bottom 52a. For this reason, the main body plane part 34d is positioned at a distance from the bottom part 52a of the attachment 5 in the vertical direction.

  As shown in FIGS. 5 to 7, in the lower surface of the main body flat portion 34 d, a protrusion 34 h that extends over the entire length along the left-right direction is provided in a region located between the two lower rails 34 b provided on the upper surface side. The projecting portion 34h is provided with a plurality of double-sided tapes 7 as adhesive members at appropriate intervals in the left-right direction. Further, a watertight material 8 surrounding each double-sided tape 7 is provided on the lower surface of the main body flat portion 34d. The watertight material 8 is made of a soft synthetic resin, and is formed, for example, from a material sheet having watertightness, punched into a rectangular shape by pressing, and connected in an annular shape. Further, when the watertight material 8 is disposed together with the double-sided tape 7, a recess is provided at a portion overlapping the protrusion 34h.

  Further, the height obtained by adding the thickness of the double-sided tape 7 to the protruding amount of the protrusion 34h protruding from the lower surface of the main body flat portion 34d is substantially the same as the height in the vertical direction of the curved extension portion 34g from the lower surface of the main body flat portion 34d. It is formed at the same height. The thickness of the watertight material 8 is slightly thicker than the height obtained by adding the thickness of the double-sided tape 7 to the protruding amount of the protruding portion 34h protruding from the lower surface of the main body flat portion 34d. For this reason, when the lower frame 34 is accommodated in the recess 52 of the attachment 5 and the lower frame 34 is attached to the attachment 5 with the double-sided tape 7, the watertight material 8 interposed between the lower frame 34 and the attachment 5 is compressed. Thus, the periphery of the double-sided tape 7 is sealed over the entire circumference. At this time, the watertight material 8 adjacent to each other is spaced from each other, and a gap is formed between the watertight material 8 adjacent to each other between the lower frame 34 and the attachment 5.

  The left and right vertical frames 35 that constitute the inner window frame 30 and are in contact with the left and right ends of the lower frame 34 protrude to the opposite sides in the left-right direction, respectively, on the indoor side edge and the outdoor side edge. An inner projecting wall 35a and an outer projecting wall 35b are provided. The lower frame 34 is fixed to the attachment 5 with the end portion inserted between the inner protruding wall 35a and the outer protruding wall 35b of the left and right vertical frames 35. For this reason, the inner projecting wall 35a is located on the indoor side of the lower frame 34 in the prospective direction, and the outer projecting wall 35b is located on the outer side of the lower frame 34 in the prospective direction.

  Then, when the lower end of the lower frame 34 and the left and right vertical frames 35 are accommodated in the recess 52 of the attachment 5, the outer protruding wall 35 b is disposed in the protruding notch 52 f at the left and right ends of the attachment 5, and the inner protruding wall 35 a is disposed in the inner wall notch 52 e at the left and right ends of the attachment 5. At this time, since the width in the left-right direction of the inner wall notch 52e is formed wider than the protruding amount of the inner projecting wall 35a, the inner wall notch 52e is located closer to the center than the inner projecting wall 35a in the inner wall notch 52e. A portion where the protruding wall 35a is not provided is provided, and the gap between the attachment 5 and the lower frame 34 is communicated with the outside.

  According to the double window 1 of the present embodiment, the inner window frame 30 attached to the frame 4 via the attachment 5 has the double-sided tape 7 attaching the lower frame 34 to the attachment 5 surrounded by the watertight material 8. Therefore, even if water enters between the attachment 5 and the lower frame 34, it is possible to prevent the double-sided tape 7 from getting wet with water. For this reason, even if water permeates between the attachment 5 and the lower frame 34, the adhesive strength of the double-sided tape 7 does not decrease, so that the lower frame 34 can be held more reliably.

  Moreover, since the watertight material 8 is connected in a ring around the double-sided tape 7, it is possible to more reliably prevent water that has entered between the attachment 5 and the lower frame 34 from coming into contact with the double-sided tape 7. It is.

  Moreover, since the watertight material 8 surrounding the double-sided tape 7 is provided in each of the plurality of double-sided tapes 7 provided with appropriate intervals in the left-right direction, the gap between the lower frame 34 and the attachment 5 is sealed over the entire length. The construction is easier than the case, and the material used for sealing is less, so the cost can be reduced.

  In addition, the watertight material 8 that surrounds each of the plurality of double-sided tapes 7 is spaced between the watertight materials 8 adjacent to each other between the main body flat surface portion 34 d and the bottom portion 52 a in the recess 52. For this reason, a gap is formed between the watertight materials 8 adjacent to each other. As shown in FIG. 5, the gap is formed between the flow path R through which the water that has entered between the main body flat portion 34d and the bottom portion 52a flows. Become. For this reason, the flow path R of the water that has entered the recess 52 is not blocked by the watertight material 8.

  Further, the inner wall portion 52b of the lower frame has a gap between the attachment 5 and the lower frame 34 and the outside at a portion where the inner protruding wall 35a is not disposed in the inner wall cutout portion 52e provided at both ends in the left-right direction. Since it communicates, the water that has entered the recess 52 can be more reliably discharged from the flow path R through the inner wall notch 52e.

  In the said embodiment, although the double window 1 which has an inner window provided with the sliding shoji was demonstrated, it is not restricted to this, For example, what is necessary is just an inner window in which a lower frame is provided via an attachment.

  Moreover, 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.
