A hollow portion 63 communicating with the lower frame 6 in the longitudinal direction is provided below the connecting flat portion 61. That is, a portion 61 a of the flat portion 61 between the existing lower screen door rail portion 62 and the lower sash door rail 6 a is located above the hollow portion 63.

  The existing lower screen door rail portion 62 is configured such that an outer wall portion 6b that forms an outdoor side wall portion of a hollow portion 63 provided below the flat portion 61 on the outdoor side of the lower sash rail 6a extends vertically above the flat portion 61. It is formed out. On the indoor side of the existing lower screen door rail portion 62, there is provided an opposing wall portion 6c which is provided to be opposed to at a slight interval and is erected on the flat portion 61, and from the upper edge of the opposing wall portion 6c. The existing lower screen door rail portion 62 is connected to the existing lower screen door rail portion 62 by an inclined portion 6d having an inclination rising toward the outdoor side.

  The existing lower screen door rail portion 62 and the opposing wall portion 6c are provided with an opening 6e penetrating in the expected direction. This is formed so that water that has entered the flat portion 61 of the lower frame 6 is discharged outside through the opening 6e. The opening 6e is provided with a drain port cover 6f that is swingably provided to cover the opening 6e and has a lid that is opened by discharged water.

  As shown in FIGS. 2 and 3, the lower screen door rail unit 10 includes a lower screen door rail 11 and a well nut 12 as a fixture for fixing the lower screen door rail 11 to the lower frame 6. . The lower screen door rail 11 is attached so that the rail portion 11a of the lower screen door rail 11 is located at a position where a portion on the distal end side of the existing lower screen door rail 62 of the existing fitting is cut off, that is, at a screen door mounting position.

  The lower screen door rail 11 is arranged above the outer wall portion 6b so as to be arranged substantially linearly with the outer wall portion 6b, and the existing lower portion which is slightly bent to the outside of the room from the lower end of the rail portion 11a and remains. An outer cover portion 11b disposed along the outdoor surface of the screen door rail portion 62, and an inner cover portion disposed along the inclined portion 6d and the opposing wall portion 6c which are bent from the lower end of the rail portion 11a to the indoor side and remain. It has a cover part 11c and a fixing part 11d that extends from the lower end of the inner cover part 11c to the indoor side, is arranged substantially parallel to the plane part 61, and is fixed to the plane part 61.

  The lower screen door rail 11 is an extruded member made of aluminum, and has a length that extends over substantially the entire length of the lower frame 6. The fixing part 11d is provided with a plurality of fixing holes 11e at appropriate intervals in the longitudinal direction.

  The well nut 12 has a fixture body 13 as a resin part made of a soft synthetic resin, and a nut 14 built in the fixture body 13. The fixture body 13 includes a cylindrical portion 13a in which a nut 14 is incorporated, and a flange portion 13c in which one end of the cylindrical portion 13a in the direction of penetration of the through-hole 13b is larger than the diameter of the cylindrical portion 13a. And The nut 14 is provided in the cylindrical portion 13a so as to be biased to the opposite side to the flange portion 13c. When the screw 8 inserted into the through hole 13b from the flange portion 13c side is screwed into the nut 14 and tightened. When the nut 14 is pulled toward the flange portion 13c, the portion of the cylindrical portion 13a closer to the flange portion 13c than the nut 14 is formed to bulge outward. The diameter of the flange portion 13c is formed smaller than the width between the lower sash rail 6a and the opposing wall portion 6c.

A method of attaching the lower screen door rail unit 10 to the existing lower frame 6 that is warped so that the height near the center in the longitudinal direction is reduced will be described.
First, as shown in FIG. 4, a part on the distal end side which is a part of the existing lower screen door rail portion 62 in which the warp has occurred is cut off. For example, a portion of the existing lower screen door rail portion 62 above a portion connected to the inclined portion 6d provided from the upper edge of the opposing wall portion 6c is cut over the entire length of the existing lower screen door rail portion 62 using an acrylic cutter or the like. I do.

  Next, the lower screen door rail 11 is fixed to the flat portion 61 between the lower screen door rail 6a for guiding the outer sash screen 3 of the lower frame 6 and the opposing wall 6c in accordance with the position of the fixing hole 11e of the lower screen door rail 11. Mounting holes 61b for the holes are formed by the drill 9 or the like. The mounting hole 61b is formed slightly larger than the diameter of the cylindrical portion 13a and smaller than the diameter of the flange portion 13c.

  Next, the tubular portion 13a is inserted into the formed mounting hole 61b from above, the well nut 12 is arranged, and the lower screen door rail 11 is arranged thereon. A gap S is provided on the outer peripheral surface of the flange portion 13c of the well nut 12 in which the cylindrical portion 13a is inserted into the mounting hole 61b, between the lower sash rail 6a and the opposing wall portion 6c. In addition, it is preferable to appropriately paint the cut portion of the existing lower screen door rail portion 62 that is exposed even when the lower screen door rail 11 is arranged.

  The lower screen door rail 11 is arranged such that the rail section 11a of the lower screen door rail 11 is positioned on the cutout where the existing lower screen door rail section 62 is cut off, and a well nut having a fixing hole 11e mounted on the plane section 61. The fixing portion 11d is placed on the flange portion 13c by aligning the positions of the through holes 13b of 12 and the fixing holes 11e. At this time, the lower screen door rail 11 is positioned by being engaged with a portion where the existing lower screen door rail portion 62 of the lower frame 6 is cut off and remains. Here, a portion formed by the outer cover portion 11b and the inner cover portion 11c of the lower screen door rail 11 corresponds to an engagement portion.

  Since the existing lower frame 6 is warped so that the height at the center side in the longitudinal direction is lower than both sides, the lower frame 6 is placed on the flange portions 13c located at both ends of the lower screen door rail 11, There is a gap in the vertical direction between the other flange 13c. For this reason, in the gap between the fixing portion 11d of the lower screen door rail 11 and the flange portion 13c, the height is adjusted by appropriately interposing, for example, a washer 15 or the like. The fixing portion 11 d of the lower screen door rail 11 is positioned above the flat portion 61 by the thickness of the flange portion 13 c of the well nut 12 and the interposed washer 15. Here, the flange portion 13c and the washer 15 of the well nut 12 correspond to a spacer. At this time, a sealing agent or the like may be filled between the existing lower screen door rail 62 and the outer cover section 11b and the inner cover section 11c of the lower screen door rail 11.

  Next, a screw 8 is inserted into each fixing hole 11 e of the lower screen door rail 11 and the through hole 13 b of the well nut 12, and screwed into a nut 14 of the well nut 12 to tighten the lower screen door rail 11 to the lower frame 6. Fix it. By tightening the screw 8, the nut 14 is drawn toward the flange portion 13 c, and the portion of the cylindrical portion 13 a on the flange portion 13 c side is fixed inside the fixing hole 11 e, the mounting hole 61 b, and the hollow portion 63 below the flat portion 61. Bulges to the outer peripheral side. The bulged portion of the cylindrical portion 13a sandwiches the fixing portion 11d of the lower screen door rail 11, the flange portion 13c of the well nut 12, and the flat portion 61 of the lower frame 6 together with the head of the screw 8 to fix the lower screen door rail 11. It is fixed to the lower frame 6. At this time, the bulged portion of the cylindrical portion 13a closes the mounting hole 61b of the flat portion 61 and stops water.

  According to the fitting 1 of the present embodiment, since the lower screen door rail 11 is formed of aluminum having higher rigidity than the synthetic resin forming the window frame 2, the lower screen door rail 11 is harder to deform than the synthetic resin rail. Further, since the lower screen door rail 11 is disposed at the screen door mounting position of the window frame 2, the screen door 4 can be disposed at an appropriate position with respect to the window frame 2. In addition, the well nut 12 fixes the lower screen door rail 11 placed on the lower frame 6 to the lower frame 6 from above the lower frame 6, so that the weight of the screen door 4 acting on the lower screen door rail 11 is reduced by the lower frame. 6 can be supported. For this reason, it is possible to equip the lower frame 6 made of synthetic resin with the lower screen door rail 11 which is not easily deformed.

  Further, since the lower screen door rail 11 is provided at a part of the lower frame 6 where a part of the resin-made existing lower screen door rail 62 is cut off, the part where the part of the existing lower screen door rail 62 is cut off is a lower screen door. When the rail 11 is fixed to the lower frame 6, it is covered by the lower screen door rail 11. For this reason, it is possible to prevent a portion of the lower frame 6 from which the existing lower screen door rail portion 62 has been cut out from being exposed to the outside.

  Further, the lower screen door rail 11 is engaged with the lower frame 6 and arranged at the screen door mounting position of the window frame 2, so that the screen door 4 supported by the lower screen door rail 11 is supported by the existing lower screen door rail section 62. It is possible to arrange them in different positions. Therefore, there is no gap between the window frame 2 and the shoji 3, so that the insect repellent performance can be maintained.

  Further, since the lower screen door rail 11 is fixed by the well nut 12, the screw 8 can be easily fixed simply by tightening the screw 8 from above. Further, when the screw 8 is tightened, the portion of the cylindrical portion 13a of the well nut 12 closer to the flange portion 13c than the nut 14 bulges in the direction in which the diameter increases, thereby closing the mounting hole 61b formed in the lower frame 6. It is possible to prevent intrusion into the hollow portion 63 located below the mounting hole 61b in the lower frame 6 such as rainwater. Further, since the lower screen door rail 11 is fixed by the well nut 12, the lower screen door rail 11 can be easily removed. Therefore, the lower screen door rail 11 can be easily replaced.

  Also, the lower screen door rail 11 is arranged such that the fixing portion 11 d does not abut on the flat portion 61 of the lower frame 6, but is spaced apart from the flat portion 61 through the flange portion 13 c of the well nut 12 and the washer 15. Since the diameter of the flange portion 13c is smaller than the width between the lower sash rail 6a and the opposing wall 6c, the water that has entered between the lower sash rail 6a and the opposing wall 6c does not prevent the water from flowing into the opening 6e. . Therefore, it is possible to prevent water from collecting between the lower sash rail 6a and the opposing wall 6c.

  As described above, it is possible to provide the fitting 1 that includes the lower screen door rail 11 that is not easily deformed and that allows the screen door 4 to be attached to the position supported by the existing lower screen door rail 62.

  In the above-described embodiment, an example in which the lower screen door rail 11 is formed of aluminum has been described. However, the present invention is not limited to this. For example, the lower screen door rail 11 may be formed of a material having a higher rigidity than a synthetic resin such as iron.

  In the above embodiment, the fixing tool is the well nut 12, but the present invention is not limited to this. For example, a fixing tool having a claw inserted from above into the mounting hole of the lower frame and locked may be used.

In the above-described embodiment, an example has been described in which the lower screen door rail unit 10 is attached to the lower frame 6 in which a part of the existing lower screen door rail 62 is cut off when the lower frame 6 is warped. Alternatively, the lower screen door rail unit 10 may be provided at the screen door mounting position of the window frame from the beginning of manufacture in a state where the lower frame is not deformed.
In the above-described embodiment, the fitting 1 provided with the sliding shoji 3 as a shoji is described as an example. However, the present invention is not limited to this, and another kind of fitting such as a sliding window may be used.

  Further, the above-described embodiment is for facilitating understanding of the present invention, and is not for limiting and interpreting the present invention. The present invention can be changed and improved without departing from the spirit thereof, and it goes without saying that the present invention includes equivalents thereof.
