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 portion in the penetration direction of the through hole 13b of the cylindrical portion 13a is larger than the diameter of the cylindrical portion 13a. And have. The nut 14 is provided in the cylindrical portion 13a so as to be biased to the opposite side to the flange portion 13c, and when the screw 8 inserted from the flange portion 13c side into the through hole 13b is screwed into the nut 14 and tightened. By pulling the nut 14 toward the flange portion 13c, the portion on the flange portion 13c side of the nut portion 14 in the tubular portion 13a is formed so as to bulge toward the outer peripheral side. In addition, the diameter of the flange part 13c is formed smaller than the width | variety of the lower shoji rail 6a and the opposing wall part 6c.

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

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

  Next, the cylindrical portion 13a is inserted into the formed mounting hole 61b from above to place the well nut 12, and the lower screen door rail 11 is placed thereon. 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, a gap S is provided between the lower shoji rail 6a and the opposing wall portion 6c. Moreover, it is preferable to apply a coating etc. suitably to the excised part of the existing lower screen door rail part 62 exposed even if the lower screen door rail 11 is arranged.

  The lower screen door rail 11 is arranged so that the rail portion 11a of the lower screen door rail 11 is positioned on the cut surface from which the existing lower screen door rail portion 62 is cut, and the well nut having the fixing hole 11e attached to the flat surface portion 61. The fixing part 11d is placed on the flange part 13c by aligning the positions of the twelve through holes 13b and the fixing hole 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, the site | part formed with the outer cover part 11b and the inner cover part 11c of the lower screen door rail 11 is equivalent to an engaging part.

  Since the existing lower frame 6 is warped so that the height on the center side in the longitudinal direction is lower than both sides, the lower frame 6 is placed on the flange portions 13c located on both ends of the lower screen door rail 11, A gap is formed between the other flange portion 13c in the vertical direction. For this reason, the height of the gap between the fixed portion 11d of the lower screen door rail 11 and the flange portion 13c is adjusted by appropriately interposing a washer 15 or the like, for example. The fixing part 11d of the lower screen rail 11 is located above the flat part 61 by the thickness of the flange part 13c 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 portion 62 and the outer cover portion 11b and the inner cover portion 11c of the lower screen door rail 11.

  Next, screws 8 are inserted into the fixing holes 11e of the lower screen door rail 11 and the through holes 13b of the well nut 12 and screwed into the nut 14 of the well nut 12 to be tightened, so that the lower screen door rail 11 is attached to the lower frame 6. Fix it. By tightening the screw 8, the nut 14 is drawn toward the flange portion 13c, and the portion of the cylindrical portion 13a on the flange portion 13c side is inside the hollow portion 63 below the fixing hole 11e, the mounting hole 61b, and the flat surface portion 61. Bulges to the outer periphery. The bulged portion of the cylindrical portion 13a is sandwiched between the head portion of the screw 8 and the fixing portion 11d of the lower screen door rail 11, the flange portion 13c of the well nut 12 and the flat surface portion 61 of the lower frame 6, so that the lower screen door rail 11 is sandwiched. Fix to the lower frame 6. At this time, the bulged portion of the tubular portion 13a closes the mounting hole 61b of the flat portion 61 and stops water.

  According to the lower screen door rail unit 10 of the present embodiment, the lower screen door rail 11 is made of aluminum having higher rigidity than the synthetic resin forming the window frame 2, and thus is less likely to be deformed than the synthetic resin rail. . Further, since the lower screen door rail 11 is disposed at the screen door attachment position of the window frame 2, the screen door 4 can be disposed at an appropriate position with respect to the window frame 2. Further, since 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, the weight of the screen door 4 acting on the lower screen door rail 11 is reduced to the lower frame. 6 can be supported. For this reason, it is possible to provide the lower screen door rail 11 which is hard to be deformed on the lower frame 6 made of synthetic resin.

  Moreover, since the lower screen door rail 11 is provided in the site | part which excised a part of the existing lower screen door rail part 62 made of resin of the lower frame 6, the site | part which excised a part of the existing lower screen door rail part 62 is the lower screen door. When the rail 11 is fixed to the lower frame 6, it is covered with the lower screen door rail 11. For this reason, it is possible to suppress that the part which cut off the existing lower screen door rail part 62 in the lower frame 6 is exposed outside.

  Further, since the lower screen door rail 11 engages with the lower frame 6 and is disposed at the screen door mounting position of the window frame 2, the screen door 4 supported by the lower screen door rail 11 is supported by the existing lower screen door rail portion 62. It is possible to arrange at different positions. For this reason, since a clearance gap does not arise between the window frame 2 and the shoji 3, it is possible to maintain insect-proof performance.

  Further, since the lower screen door rail 11 is fixed by the well nut 12, it can be easily fixed only by tightening the screw 8 from above. Further, when the screw 8 is tightened, the flange 13c side of the tubular portion 13a of the well nut 12 bulges in a direction in which the diameter of the flange portion 13c is increased, 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 attachment 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. For this reason, it is also possible to replace the lower screen door rail 11 easily.

  In addition, the lower screen door rail 11 is arranged such that the fixing portion 11 d is not in contact with the flat portion 61 of the lower frame 6 and is spaced from the flat portion 61 by way of the flange portion 13 c and the washer 15 of the well nut 12. Since the diameter of the flange portion 13c is smaller than the width of the lower shoji rail 6a and the opposing wall portion 6c, it does not prevent the water that has entered between the lower shoji rail 6a and the opposing wall portion 6c from flowing into the opening 6e. . For this reason, it is possible to prevent water from accumulating between the lower shoji rail 6a and the opposing wall portion 6c.

  Thus, it is possible to provide the joinery 1 that includes the lower screen door rail 11 that is not easily deformed and that can be attached to the screen door 4 at the position supported by the existing lower screen door rail portion 62.

  In the said embodiment, although the example in which the lower screen door rail 11 was formed with aluminum was demonstrated, it is not restricted to this, For example, what is necessary is just formed with the material whose rigidity is higher than synthetic resins, such as iron.

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

In the said embodiment, when the lower frame 6 warped, the example which attaches the lower screen door rail unit 10 to the lower frame 6 which excised a part of the existing lower screen door rail part 62 was demonstrated, but it does not restrict to this. The lower screen door rail unit 10 may be provided at the screen door attachment position of the window frame from the beginning of manufacture in a state where the lower frame is not deformed.
In the said embodiment, although the joinery 1 provided with the sliding shoji 3 as a shoji was mentioned as an example, it was not restricted to this, You may be other kinds of joinery, such as an open window.

  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.
