A portion 42 b extending to the indoor side of the existing vertical frame bracket 42 a is disposed in parallel to the surface along the prospective direction of the rectangular hollow portion 37 a of the vertical frame bonding member 37 and is provided from the vertical frame bonding member 37. It is arranged on the vertical frame 53 side. The refurbished vertical frame bracket 42c is screwed to the surface facing the indoor side of the refurbished vertical frame extending portion 23c, and is extended to the indoor side from the existing vertical frame 53, the refurbished vertical frame 23, and the vertical frame connecting member 37 to be installed in the existing vertical frame. It joins with the site | part 42b extended to the room inner side of the frame bracket 42a with the screw | thread.

  When the vertical frame joining member 37 is fixed to the existing vertical frame 53 and the refurbished vertical frame 23, the vertical frame joining member 37 is arranged so as to cover the lower joining member extending portion 36 f extending on both sides in the finding direction. That is, a watertight material (not shown) provided at the left edge of the lower joint member extension 36f is brought into contact with the lower edge of the left wall of the hollow part 37a of the vertical frame joint 37. Placed in. In addition, the refurbished lower frame 22 of the present embodiment has a frame in which the end in the prospective direction is in contact with the inner peripheral side surface of the refurbished vertical frame 23, so The outer side of the refurbished vertical frame main body portion 23b is a lower joint member extending portion 36f. For this reason, the water flowing in the space sandwiched between the refurbished vertical frame main body 23b and the vertical frame joining member 37 and the hollow portion 37a of the vertical frame joining member 37 in the finding direction also reaches the lower joining member extending portion 36f to the outdoor. To be discharged. In FIG. 2, the communication portion 36 g is provided only under the hollow portion 37 a of the vertical frame joining member 37, but in the space between the refurbished vertical frame main body portion 23 b and the vertical frame joining member 37 in the finding direction. It may extend to.

  According to the modified sash unit 1 of the present embodiment, the lower joint member extending portion 36f that has entered the lower side of the modified sash 10, e.g., condensed water, is extended outward from the modified lower frame 22 in the direction of finding. Since it leads to the existing lower frame 52, the indoor side leg 22e, the central leg 22f, the outdoor leg 22g, and the existing frame 50 provided to support the refurbished frame 20 are provided. Without avoiding the existing inner lower rail 52a, the existing outer lower rail 52b, the existing screen door lower rail 52c, etc., it is possible to secure a drainage path that facilitates water flow. At this time, water is provided to the existing lower frame 52 through the communicating portion 36g provided in the lower joining member extending portion 36f and communicating with the space above and below the lower joining member extending portion 36f. It is possible to easily bring the water that has reached 36f to the existing lower frame 52 from the communication portion 36g. In addition, since the existing lower frame 52 is a lower frame of an existing sash that has already been installed, the water that has reached the existing lower frame 52 can be easily discharged from the drainage path provided in the existing lower frame 52 to the outside. Is possible.

  Further, for example, when there is a large amount of condensed water, there is a possibility that water will overflow on the refurbished picture frame 60, and when the seal on the refurbished picture frame 60 is broken with the refurbished lower frame 22, There is a risk of entering the lower side of the remodeling sash 10 from the gap with the remodeling lower frame 22. According to the refurbished sash unit 1 of the present embodiment, even when water enters the lower side of the refurbished sash 10 through the gap between the refurbished frame 60 and the refurbished lower frame 22, the water is provided below the refurbished frame 60. The water receiving member 48 protruding from the outdoor edge 60a of the refurbished frame 60 to the indoor side can reliably discharge the water that has entered the lower side of the refurbished frame 60 to the outside.

  Further, since the water receiving member 48 communicates with the lower joint member extending portion 36f outside the modified lower frame 22 in the finding direction, the water that has reached the water receiving member 48 is restored in the finding direction. It is possible to reach the lower joining member extending portion 36f on the outer side. For this reason, since the modified inner lower rail 22a, the modified outer lower rail 22b, etc. of the modified lower frame 22 do not protrude into the water path, the water reaching the water receiving member 48 is efficiently brought to the lower joint member extending portion 36f. It is possible.

  In addition, since the frame support portion 48e that supports the refurbished frame 60 is provided on the indoor side of the water receiving member 48, the refurbished frame 60 and the water receiving member 48 can be accurately arranged. For this reason, it is possible to reliably reach the water receiving member 48 from the water entering from the outdoor edge 60a of the refurbished frame 60. Furthermore, since the refurbished frame 60 is supported by the frame support portion 48e, the strength of the refurbished frame 60 can be increased. In particular, the renovated frame 60 having a wide width in the prospective direction as in the present embodiment may be loaded by a user wearing a hand or placing a figurine when opening and closing the shoji. Even so, since the refurbished frame 60 is supported by the frame support portion 48e of the water receiving member 48, it is possible to provide sufficient strength.

  Further, since the frame support portion 48e, which is a portion of the water receiving member 48 on the indoor side, is brought into contact with the lower side of the refurbished frame 60, the water transmitted downward from the outdoor edge 60a of the refurbished frame 60 It is possible to prevent returning to the indoor side along the lower side.

  Further, the lower joint member extending portion 36 f serving as a water drainage path is interposed between the existing vertical frame 53 located on the side of the existing frame 50 and the refurbished vertical frame 23 located on the side of the refurbished frame 20. The space between the existing vertical frame 53 and the refurbished vertical frame 23 can be kept small since there is no need to provide a separate space for providing the lower bonding member extending portion 36f. In addition, since the lower joining member extending portion 36f is hidden by the refurbished vertical frame 23 and the vertical frame joining member 37, it is possible to prevent the drainage path from being exposed to the outside.

  In the present embodiment, the example in which the water receiving member 48 is formed separately from the lower frame joining member 36 has been described. However, the fixed wall portion 48a of the water receiving member 48 and the indoor vertical wall portion 36a of the lower frame joining member 36 are described. And may be integrated as the same part.

  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.
