Description

  The present invention relates to a renovated sash for refurbishing a window by attaching a new frame inside an existing frame.

As a conventional remodeling sash, Patent Document 1 discloses that the auxiliary auxiliary member is screwed to the indoor guide rail of the existing lower frame, and the outdoor guide rail of the existing lower frame is cut and removed, and the inner side of the existing frame is removed. The new frame is fitted from the outside, the upper part on the indoor side of the new lower frame is screwed to the mounting aid from above, and the lower part on the outer side of the new lower frame is screwed to the existing lower frame from the outside of the room. Yes. In this refurbished sash, when the new frame is installed in the existing frame, the new lower frame is simply put on the auxiliary mounting material, so the new lower frame may be shifted to the outside of the outdoor frame, and Installation of the new frame was not easy because it had to be screwed from two directions outside the room.
In addition, the refurbished sash described in Patent Document 2 has a lower frame fixing material protruding upward screwed to the upper part on the indoor side of the existing lower frame, and the newly installed lower frame is attached to the upward recess provided on the outdoor side surface of the lower frame fixing material. By locking the upper part on the indoor side, the new frame can be installed easily. However, in this refurbished sash, the lower frame fixing material protrudes upward from the existing lower frame, and the new lower frame is placed in the upward recess of the lower frame fixing material, so the new lower frame is located at a position considerably higher than the existing lower frame. Therefore, there is a disadvantage that the opening area of the window becomes narrower than that before the renovation.
In addition, in the conventional sash, condensation is likely to occur at the angle of the lower frame, and it is necessary to wipe off the condensed water occasionally with a dust cloth or the like. As described in Patent Document 3, there is a drainage device provided in the groove portion where the shoji of the lower frame travels, so that rainwater and dew condensation water collected in the groove portion of the lower frame can be drained outdoors, There was nothing that could drain the condensed water accumulated on the angle of the lower frame.

Next, an example of the construction procedure of this remodeling sash will be described. First, as a preparation for installing the new frame 10, the outdoor rail 20 of the existing lower frame 1 is cut out, the lower frame auxiliary material 2 is attached to the inner peripheral side of the existing lower frame 1 with screws 24 a and 24 b, and the existing upper frame 12 The upper frame auxiliary member 40 is attached to the inner peripheral side with screws 44a and 44b, and the heel frame auxiliary member 57 is attached to the inner peripheral side of the left and right existing ridge frames 13 with screws 60a and 60b. Next, the new lower frame 3, the new upper frame 16, and the left and right new saddle frames 17, 17 are framed in four directions to form the new frame 10.
Next, the new frame 10 is fitted into the existing frame 9 from the outdoor side. At this time, as shown in FIG. 3, the engaged portion 6 provided on the indoor side of the newly installed lower frame 3 is engaged with the engaging portion 5 of the lower frame auxiliary material 2 from above so that the weight of the newly installed frame 10 is increased. Is supported by the lower frame auxiliary material 2, and the new lower frame 3 is positioned in the vertical direction and the indoor / outdoor direction. Thereafter, the new upper frame 16 is abutted against the outdoor end of the upper frame auxiliary member 40, and then a spacer 52 is inserted into the gap between the upper frame auxiliary member 40 and the new upper frame 16, as shown in FIG. The new upper frame 16 is screwed to the upper frame auxiliary member 40 with screws 51 from the inner periphery side, and a spacer 63 is inserted into the gap between the vertical frame auxiliary material 57 and the new auxiliary frame 17 to assist the new auxiliary frame 17 with the auxiliary frame frame. The new frame 10 is fixed to the existing frame 9 by screwing to the material 57 from the inner peripheral side with screws 62 and screwing the lower outer side of the new lower frame 3 to the existing lower frame 1 with screws 30 from the outer side. .
Next, the upper end portions of the left and right eaves cover receiving members 58, 58 are connected to both ends of the upper cover receiving member 41 with screws (not shown), and the cover receiving members 41, 58, 58 are framed in a gate shape. Next, as shown in FIG. 4, the upper cover receiving member 41 is screwed to the indoor side of the new upper frame 16 with a screw 53, and the eaves cover receiving member 58 is screwed to the indoor side of the new upper frame 17 with a screw 66. To do. Thereafter, the upper cover 42 is engaged and attached to the indoor side of the upper cover receiving member 41, and the eaves cover 67 is engaged and attached to the indoor side of the eaves cover receiving member 58. Finally, the inner shoji 11a and the outer shoji 11b are installed in the new frame 10.

  As described above, the remodeled sash can be easily renovated by inserting and fixing the new frame 10 inside the existing frame 9 from the outdoor side without removing the existing frame 9. When the new frame 10 is fitted into the existing frame 9, the engaged portion 6 provided on the indoor side of the new lower frame 3 is engaged with the engagement portion 5 of the lower frame auxiliary material 2, thereby Easy installation. Further, since the engaging portion 5 of the lower frame auxiliary material 2 is positioned below the angle portion 4 and the outdoor rail 20 of the existing lower frame 1 is cut away, the new lower frame 3 is replaced with the existing lower frame 1. Since it can be placed at a low position close to the, a large opening area can be secured. Furthermore, in this remodeled sash, a drain valve 7 is provided in the angle part 4 of the lower frame auxiliary material 2, and when condensation occurs in the angle part 7, the condensed water flows into the lower frame from the drain valve 7, and the existing lower frame Since it flows to the outside of the room through the upper surface 18 and is drained to the outside through the drain hole 31 provided in the lower outside of the newly installed lower frame 3, the dew condensation can be done without wiping away the dew condensation water of the angle part 4 with a rag or the like. The floor can be prevented from getting wet by water. In addition, since the renovated sash has resin covers 42 and 67 installed on the indoor side of the newly installed upper frame 16 and the newly installed frame 17, the existing frame 9, screws for attaching the existing frame 9 and the newly installed frame 10, etc. Is concealed by the cover, improving the interior design and preventing the occurrence of condensation. Since the covers 42 and 67 are attached to the cover receiving members 41 and 58 by engagement, the attachment is easy.

  The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the present invention. The structure of the window frame, such as a portion for guiding the sliding shoji, and the structure of the shoji itself are arbitrary. The structure of the drain port is not limited to a structure in which a drain valve or a drainage member having no valve is attached to a hole formed in the angle part, and may be a structure in which a small hole is formed in the angle part. The shape of the existing lower frame or the new lower frame is not particularly limited, but it is possible to allow dew condensation water from the drainage outlet to drain to the outside through the lower frame. The lower frame auxiliary material, the upper frame auxiliary material, and the eaves frame auxiliary material may be formed integrally and attached over substantially the entire length on the inner peripheral side of the existing frame material. And may be attached with an interval in the longitudinal direction of the existing frame member.
