The upper stage 21 is formed more indoors than the lower stage 22 in the longitudinal direction of the lower frame 2b, and the upper surface is a substantially horizontal surface. A hanging piece 24 is provided at the outdoor end of the upper stage 21. The lower stage 22 is formed in the outdoor side edge part of the lower frame 2b over the longitudinal direction of the lower frame 2b, and the upper surface is inclined gently so that it may become high toward the indoor side. Between the upper stage 21 and the lower stage 22, the groove part 23 opened in the expected direction is formed. The groove portion 23 is a space formed by the lower surface of the upper stage 21 and the upper surface of the lower stage 22, and the outdoor side is open.

The lowering stop member 3 is made of resin, and is a member that is attached to a substantially central portion in the longitudinal direction of the lower frame 2 b and supports the shoji 1 during the curing of the glass 12. As shown in FIGS. 1 and 3, the lowering stop member 3 of the first embodiment includes a support portion 31 and an attachment portion 32.
The support part 31 is located in the upper part of the attachment part 32, and supports the shoji 1 on the upper surface of the lower frame 2b. The support part 31 includes a height adjustment part 31a and a base part 31b. The height adjusting portion 31 a is located at the upper portion of the base portion 31 b, and the upper surface thereof is in contact with the lower surface of the shoji 1. The base 31b has a substantially horizontal lower surface and comes into contact with the upper surface of the lower frame 2b. At the indoor side end of the base portion 31b, an engaged portion 31e protruding toward the indoor side is formed. The height adjusting part 31a is connected to the base part 31b by a cutting part 31c provided at the outdoor side end part, and is rotatable about the cutting part 31c as shown in FIG. Since the cutting part 31c is formed thinner as it approaches the base part 31b, the operator can easily separate the height adjustment part 31a from the base part 31b. Moreover, the height adjustment part 31a is provided with the engaging part 31d with the base 31b in the indoor side edge part. The engaging portion 31d is formed in a hook shape protruding outward, and engages with an engaged portion 31e provided on the base portion 31b to integrate the height adjusting portion 31a and the base portion 31b.
The attachment part 32 attaches the lowering stop member 3 to the lower frame 2b, and includes an engagement part 32a and a spring part 32b. Specifically, a hanging portion 32d is formed from the outdoor side end portion of the base portion 31b. The hanging part 32d is formed slightly longer than the hanging piece 24 of the lower frame 2b. A locking portion 32a is formed from the lower end of the hanging portion 32d toward the indoor side. The locking portion 32a is locked to the hanging piece 24 of the lower frame 2b. The locking portion 32a is a deformed portion that bends upward in a mountain shape, and is deformed so as to open in the expected direction when a load is applied to the mounting portion 32. A spring portion 32b is formed from the locking portion 32a toward the indoor side. The spring portion 32 b is formed by bending in a mountain shape toward the indoor side, is bent and deformed in the vertical direction, and has an urging force in the vertical direction while being fitted in the groove portion 23. And the contact part 32c is formed toward the outdoor side from the downward direction of the spring part 32b. The contact portion 32c is gently inclined so as to become lower toward the outdoor side, and the lower surface thereof contacts the upper surface of the lower stage 22 of the lower frame 2b.

The fall stop member 3 may be used by separating the height adjusting portion 31a from the base portion 31b in accordance with the form of the sash. Further, the height adjusting member 4 may be attached to the lower surface of the shoji 1.
The sash of 2nd embodiment is demonstrated. The sash of the second embodiment shown in FIG. 4 is different from the sash of the first embodiment shown in FIG. 1 in the distance between the lower surface of the shoji 1 and the upper surface of the lower frame 2b. In this case, the height adjusting portion 31 a is separated from the base portion 31 b of the lowering stop member 3, and the height adjusting member 4 is attached to the lower surface of the shoji 1. Even if the height adjusting portion 31a is cut off, only the base portion 31b can function as the support portion 31, and the lowering preventing member 3 is lowered by the lower surface of the height adjusting member 4 coming into contact with the upper surface of the base portion 31b. The effect of stopping can be demonstrated.

Here, the construction procedure of a sash is demonstrated.
First, the housing 11 and the frame 2 of the shoji 1 are assembled. Then, the hinge of the casing 11 is aligned with the upper frame 2 a and screwed to connect the casing 11 and the frame 2.

  Next, with the housing 11 opened, the lowering prevention member 3 is attached to the substantially central portion in the longitudinal direction of the lower frame 2b. The attachment procedure will be described with reference to FIG. The lowering stop member 3 is attached from the outdoor side toward the indoor side. As shown in FIG. 5 (b), while the lower surface of the support portion 31 is along the upper surface of the upper stage 21 of the lower frame 2b and the contact portion 32c is along the upper surface of the lower step 22, the lowering prevention member 3 is moved from the outdoor side. Translate inward. When the locking portion 32a is inserted into the hanging piece 24, the locking portion 32a opens in the expected direction, and the spring portion 32b is elastically deformed. Get stuck. As shown in FIG. 5C, in the state where the lowering prevention member 3 is attached to the lower frame 2b, the hanging piece 24 is locked by the locking portion 32a, and the spring portion 32b is fitted in the groove portion 23. The abutting portion 32 c abuts on the upper surface of the lower stage 22.

  The sash is carried into the construction site with the lowering prevention member 3 attached. At the construction site of the sash, the frame body 2 is attached to the opening of the housing, and the glass 12 is fitted into the inner periphery of the housing 11. Then, the glass 12 is fixed to the casing 11 by applying a sealant between the glass 12 and the casing 11 with the shoji 1 closed. After the sealing agent is cured, the fall stop member 3 is removed in a state where the shoji 1 is opened, and adjustment of building is performed.

  The procedure for removing the lowering stop member 3 from the lower frame 2b will be described with reference to FIG. First, with the contact portion with the lower end of the drooping piece 24 as a fulcrum, the support portion 31 is pivoted vertically from the indoor side to the outdoor side. The spring portion 32b is bent and deformed, and in the state of FIG. 6B, the contact portion 32c is separated from the upper surface of the lower stage 22 on the indoor side. Further, when the support portion 31 is rotated in the horizontal direction so as to be twisted, the locking portion 32a is deformed so as to open in the expected direction and the spring portion 32b is bent and deformed, as shown in FIG. The stop portion 32 a is detached from the hanging piece 24, and the attachment portion 32 is detached from the groove portion 23.
