The attachment of the functional fitting 6 using the auxiliary pillar 7 in the opening device of this embodiment will be further described below.

[0025] The auxiliary pillar 7, which is fixed to the indoor side of the left vertical frame 23 of the inner shoji screen 2, is made of a metal material such as aluminum alloy, and as shown in Figure 3, is a hollow, elongated member with an approximately rectangular cross section consisting of an indoor side wall 71, an outdoor side wall 72, and left and right side walls 73, 73, with the upper and lower portions of the outdoor side wall 72 cut out to form upper and lower cutouts 72a, 72b.

[0026] The auxiliary pillar 7 has the outdoor ends of the left and right side walls 73, 73 extending outside the room beyond the connection with the outdoor wall 72, and airtight material mounting portions 73a, 73a that open inward are provided at the portions of the left and right side walls 73, 73 extending outside the room.

[0027] The auxiliary pillar 7 has an exterior side surface 72c formed by the central portion of the exterior wall 72 protruding outside the room, and the prospective position of the exterior side surface 72c is located at the same position as or slightly outside the prospective position of the exterior end of the portion of the side walls 73, 73 extending outside the room.

[0028] The auxiliary pillar 7 has airtight materials s7, s7 attached to the airtight material mounting portions 73a, 73a of the side walls 73, 73, which protrude outside from the outside end of the side wall 73, and if necessary, two strips of double-sided tape 75 extending in the vertical direction are adhesively fixed to the central region in the viewing direction of the outside surface 72c of the outside wall 72. The airtight materials s7, s7 attached to the airtight material mounting portions 73a, 73a of the side walls 73, 73 are positioned from the upper end of the auxiliary column 7 to the upper end position of the lower notch portion 72b, and are not positioned in the area where the lower notch portion 72b is present.

[0029] The auxiliary pillar 7 has two ribs 73b, 73b formed on the left and right inner surfaces of the side walls 73, 73 on the outside of the room, and screw holes 73c, 73c are formed at upper and lower positions between the two ribs 73b, 73b for fixing to the fixing brackets 81, 82 described later.

[0030] The left vertical frame (vertical member) 23 of the inner shoji screen 2 fixed to the frame body 1 has a resin upper end cap (cap member) 51 and a resin lower end cap (cap member) 52 attached to the upper and lower ends, as shown in Figure 4. The upper end cap (cap member) 51 is attached by inserting an insertion portion (not shown) into the hollow portion of the left vertical frame (vertical member) 23 of the inner shoji screen 2, and the upper surface of the left vertical frame (vertical member) 23 is covered by the lid portion 51a, the upper surface of which abuts against the upper inner surface of the opening.

[0031] The lower end cap (cap member) 52 is attached so as to cover the lower part of the left vertical frame (vertical member) 23 of the inner shoji screen 2, and covers the underside of the left vertical frame (vertical member) 23 with the lid portion, and also covers the lower outer peripheral surface of the left vertical frame (vertical member) 23 with the side wall portions 52b, 52b that rise from the outer periphery of the lid portion.

[0032] The fixing brackets 81, 82 are short members made of a metal material such as steel and having a roughly U-shaped cross section. As shown in FIG. 4, they have mounting walls 81a, 82a fixed to the upper and lower inner surfaces of the opening along the projection direction, and left and right side walls 81b, 82b extending inward from the left and right edge portions of the mounting walls 81a, 82a.

[0033] The upper fixing bracket 81 is formed so that the width of the left and right side walls 81b, 81b in the prospective direction becomes shorter as it goes downward, and the outdoor side edge and indoor side edge of the side wall 81b are formed so that they get closer as they go downward. The fixing brackets 81 and 82 have two screw holes 81c, 81c, 82c, and 82c (Figure 6) formed in the mounting walls 81a and 82a, through which a screw (fixing means) b1 is passed, and the upper fixing bracket 81 has double-sided tape 81d adhered between the screw holes 81c and 81c on the upper surface of the mounting wall 81a.

[0034] (Installation procedure) When attaching the functional fitting 6 to the opening device, first, the fixing metal fittings 81 and 82 for attaching the auxiliary pillars 7 are fixed to the inner periphery of the opening. As shown in Figure 4, the upper fixing bracket 81 is slid from the inside of the room along the upper inner surface of the opening toward the left vertical frame (vertical member) 23, so that the outside end of the mounting wall 81a abuts against the lid portion 51a of the upper end cap (cap member) 51 attached to the upper end of the left vertical frame (vertical member) 23.

[0035] As shown in Figure 5, the upper fixing bracket 81 abutting the upper end cap (cap member) 51 has the outdoor side edges of the left and right side walls 81b, 81b inclined in a direction away from the end edge of the mounting wall 81a as they go downward, so that the side walls 81b, 81b of the fixing bracket 81 do not abut against the indoor side surface of the left vertical frame (vertical member) 23, and the metal materials do not come into contact with each other.

[0036] The upper fixing bracket 81 is positioned on the indoor side of the left vertical frame 23, with the outdoor end of the mounting wall 81a abutting the upper end cap (cap member) 51, and the double-sided tape 81d on the upper surface of the mounting wall 81a being adhesively fixed to the inner surface above the opening.

[0037] As shown in Figure 4, the lower fixing bracket 82 is slid from the inside of the room along the lower inner surface of the opening toward the left vertical frame (vertical member) 23, and as shown in Figure 5, the outside ends of the mounting wall 82a and the left and right side walls 82b, 82b are abutted against the side wall portion 52b of the lower end cap (cap member) 52 attached to the lower end of the left vertical frame 23, and it is positioned on the inside of the left vertical frame 23.

[0038] Upper and lower fixing metal fittings 81, 82 arranged on the indoor side of the left vertical frame (vertical member) 23 are fixed to the inner peripheral surface with screws (fixing means) b1, b1 from the inner peripheral side, as shown in FIG.

[0039] Next, the auxiliary column 7 is fixed to the inner periphery of the opening via fixing brackets 81 and 82. As shown in Figure 7, the auxiliary column 7 is aligns the upper and lower notches 72a, 72b with the fixing brackets 81, 82 fixed to the upper and lower inner surfaces of the opening, and is slid from inside the room so that the fixing brackets 81, 82 are inserted into the hollow portion of the auxiliary column 7 through the upper and lower notches 72a, 72b. In FIG. 7, the screws b1 and the like are omitted as appropriate.

[0040] The auxiliary column 7 is formed with dimensions such that even when the fixing brackets 81, 82 are inserted deep inside the hollow portion, the outdoor ends of the side walls 73, 73 do not abut against the indoor side surface 23p of the left vertical frame (vertical member) 23, and the auxiliary column 7 is positioned with a gap between the side walls 73, 73 of the auxiliary column 7 and the indoor side surface 23p of the vertical member 23. However, as shown in Figure 8, the airtight materials s7, s7 protruding to the outside from the outdoor ends of the side walls 73, 73 abut against the indoor side surface 23p of the left vertical frame (vertical member) 23, sealing the gap between the auxiliary column 7 and the vertical member 23. In addition, if double-sided tape 75, 75 is provided on the outdoor side surface 72c of the outdoor wall 72 of the auxiliary pillar 7, the outdoor side of the double-sided tape 75, 75 is adhered to the indoor side surface of the vertical member 23, integrating the auxiliary pillar 7 and the left vertical frame (vertical member) 23.

[0041] The auxiliary pillar 7, which is located on the indoor side of the left vertical frame (vertical member) 23, is connected to the upper and lower fixing brackets 81, 82 by drilling screws or the like (fixing means) b2, b2 through screw holes 73c, 73c in the left and right side walls 73, 73, as shown in Figure 9, and is fixed to the opening via the fixing brackets 81, 82.

[0042] As shown in Figure 2, the functional fitting 6 is attached to the interior side of the left side of the opening by fixing the left vertical frame 63 to the vertical projected surface a of the opening and the right vertical frame 64 to the projected surface 7a of the auxiliary pillar 7 with screws or the like (fixing means) b3, b3. The above describes the procedure for installing functional fixtures.

[0043] -Effects of the opening device of this embodiment- The opening device of this embodiment has auxiliary pillars attached using fixing brackets fixed to the upper and lower inner surfaces of the opening, and the vertical frame of the accordion screen door attached between the auxiliary pillars and the inner surface of the building opening, so that functional fixtures can be attached without requiring any processing such as drilling in the fixtures that make up the opening device, preventing a decrease in strength or fire resistance due to processing such as drilling.

[0044] The opening device of this embodiment has resin cap members attached to the top and bottom of the metal vertical members of the fittings to be installed in the opening, and fixing brackets are positioned so that they abut against the cap members, so the fixing brackets can be easily positioned and it is easy to install.

[0045] The opening device of this embodiment avoids contact between the fixing brackets and the metal vertical members, and by arranging the metal vertical members of the building fixtures and the auxiliary columns so that they do not abut each other but leave a gap, and by sealing the gap with an airtight material, it is possible to prevent insects from entering through small gaps that occur where the metal members abut each other and to prevent noise and other issues caused by metal members coming into contact with each other. Furthermore, in the opening device of this embodiment, the auxiliary columns are less likely to form condensation.

[0046] In the opening device of this embodiment, the auxiliary pillars are formed from hollow members and attached to the exterior side with double-sided tape to adhere to the vertical members of the fixture, and two strips of airtight material are placed along the entire length at both the left and right ends of the exterior side, so that the adhesive surface that integrates the vertical members of the fixture and the auxiliary pillars is covered with two strips of airtight material, thereby preventing deterioration of the adhesive surface.

[0047] In the opening device of this embodiment, an accordion screen door is exemplified as an example of functional fittings, which consists of a screen door (functional component) that can be extended and closed freely between the left and right vertical frames 63, 64, but functional fittings are not limited to accordion screen doors such as handrails.

[0048] Furthermore, the fixtures for the opening device are not limited to externally operated single sliding windows, but may be, for example, an opening device with a casement window arranged in half of the opening, or a continuous window with openings on both sides of a mullion, and the type of window is not limited. Furthermore, the vertical members of the opening device that are placed on the outside of the auxiliary pillars are not limited to the vertical frames of inner shoji screens, but may also be other vertical frames, mullions, etc. In addition, it goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples.
