The fitting exemplified here is called an indoor single sliding door in which one door 20 is movably arranged inside the frame 10 . A rectangular opening area 5 surrounded by left and right pillars 2 and 3 and a lintel 4 is formed in a frame wall 1 on which fittings are installed. In this opening area 5, the distance between the left and right pillars 2, 3 is set to be shorter than twice the dimension along the left and right sides of the door 20. As shown in FIG. A wing wall 6 (wall body) is provided inside the opening region 5 so as to continue from one of the pillars 2 . The sleeve wall 6 is constructed by arranging the interior material 8 on the surface of the base material 7, and has a size smaller than that of the wall 1 in the projection direction and a size that covers the majority of the opening area 5. there is In this embodiment, when the lower side of the wall 1 is the chamber A and the upper side of the wall 1 is the chamber B in FIG. It is directed to the facing surface, and the wall 1 and the wing wall 6 are located on the same plane. Between the sleeve wall 6 and the other pillar 3, there is secured a passage opening (opening) 9 which communicates between the A chamber and the B chamber and which can be closed by a door member 20. - 特許庁As described above, since the distance between the pillars 2 and 3 is shorter than twice the length of the door 20, the edge of the surface of the side wall 6 facing the chamber A located on the side of the passage opening 9 is , is always covered by the door 20 regardless of the opening/closing position of the door 20. - 特許庁A base material 7 of the sleeve wall 6 is provided with an interior material 8 so as to cover the inner peripheral surface of the passage opening 9 and the surface facing the A chamber. Reference numeral 8a in the drawing denotes a baseboard provided at the lower edge of the interior material 8. As shown in FIG.

The frame body 10 includes an upper frame 13 between the upper ends of the left and right vertical frames 11 and 12 and a lower rail 14 between the lower ends of the vertical frames 11 and 12. It is arranged in the part which becomes the A chamber side rather than the sleeve wall 6. - 特許庁That is, in this fitting, the frame 10 is arranged on the surface side of the sleeve wall 6 facing the A room. The vertical frames 11 and 12, the upper frame 13, and the lower rail 14 are extruded members made of metal such as aluminum alloy or resin, and are configured to have a uniform cross-sectional shape along the entire length along the length. There is. In the illustrated example, projection fins 11a, 12a, and 13a extending in the projection direction toward the A chamber are provided on the inner peripheral edge portions of the vertical frames 11, 12 and the upper frame 13, respectively, located on the A chamber side. are applied. The vertical frames 11, 12 and the upper frame 13 are almost covered by the interior material 8 of the chamber A covering the surface of the wall 1 up to a position contacting the fins 11a, 12a, 13a. From the side, only protruding edges of the prospective fins 11a, 12a, and 13a are visible.

Further, the frame body 10 is provided with an intermediate mullion 15 between the projection surface 13b on the inner peripheral side of the upper frame 13 and the floor plate 30. - 特許庁Like the vertical frames 11 and 12, the central mullion 15 is an extruded shape member made of metal such as an aluminum alloy or resin, and is constructed so that the entire length along the length has a uniform cross-sectional shape. . In this embodiment, as shown in FIG. 5, a central mullion 15 having a mullion main body portion 15a and a mounting plate portion 15b is exemplified. The cubic main body 15a is in the shape of a hollow rectangular tube configured so that the dimension along the left-right direction is larger than the dimension along the projection direction. A mohair 16 is attached via a mounting groove 15c in a substantially central portion of the face of the cubic main body 15a facing the A chamber. The mounting plate portion 15b has a flat plate shape extending in the viewing direction, and has supporting plate portions 15d and 15e along the viewing direction on both side edges thereof. The mounting plate portion 15b is formed integrally with the mullion main body portion 15a in a state in which one support plate portion 15d is connected to a corner portion of the mullion main body portion 15a on the outer peripheral side of the passage opening 9. . The other supporting plate portion 15e of the mounting plate portion 15b extends to the facing surface facing the A chamber of the mullion body portion 15a, and detachably supports the cap member 17 between itself and the mullion body portion 15a. ing. The cap member 17 is for covering the screw S (see FIG. 6) screwed into the mounting plate portion 15b.

After the vertical frames 11 and 12 and the upper frame 13 are attached to the wall 1, as shown in FIGS. 4 and FIG. 6(b), the sleeve wall is arranged between the upper surface of the floor plate 30 and screws S are screwed into the base material 7 of the sleeve wall 6 via the mounting plate portion 15b. In 6, they are arranged vertically along the edge of the surface facing the A chamber. In the central mullion 15 supported by the sleeve wall 6, a part of the mullion main body 15a protrudes from the interior material 8 toward the inner peripheral side of the passage opening 9, and is positioned at the opening/closing position of the door 20 from the A chamber side. Regardless, the dimension along the view direction is set so that it is always covered by the door 20. - 特許庁

On the other hand, as is clear from FIG. 6(b), the dimension along the length of the mullion 15 is set smaller than the distance from the projected surface 13b of the upper frame 13 to the upper surface of the floor board 30. As shown in FIG. Therefore, when the central mullion 15 is supported by the sleeve wall 6, it can be easily and surely arranged between the upper frame 13 and the floor board 30, and the length of the central mullion 15 can be adjusted by cutting the middle mullion 15 on site. No work occurs.

However, while the lower end of the mullion 15 supported by the wing wall 6 abuts on the upper surface of the floor plate 30, a gap is generated between the upper end and the projected surface 13b of the upper frame 13. Even when the base material 7 of the sleeve wall 6 is covered with the interior material 8, this gap can be visually recognized from the side of the chamber B and the inner peripheral side of the opening 9 for passage. For this reason, this fitting is provided with a cover member 18 for covering the mullion body 15a of the central mullion 15. As shown in FIG. The cover member 18, as shown in FIGS. 5 and 7, has an expected cover portion 18a and an additional cover portion 18b. The prospective cover portion 18a has a rectangular shape having a size sufficient to cover the entire prospective surface 15f, which is the inner peripheral side of the passage opening 9, at the upper end of the cubic main body portion 15a. The prospective cover portion 18a has a rectangular shape and is large enough to cover the entire face 15g facing the B chamber at the upper end of the cubic body portion 15a. The cover member 18 may be made of metal or resin. In this embodiment, a cover member 18 made of stainless steel (SUS) and formed into a thin plate is applied.

As shown in FIGS. 8(a) and 8(b), the cover member 18 is mounted before the interior material 8 is attached to the sleeve wall 6 after the inner mullion 15 is supported by the base material 7 of the sleeve wall 6. It is attached to the upper end of the central mullion 15 so as to protrude from the upper end of the central mullion 15 in the state. As a method for attaching the cover member 18 to the central mullion 15, the cover member 18 and the surface of the central mullion 15 may be adhered with a double-faced tape. In this case, it is not always necessary to adhere both the prospective cover portion 18a and the finding cover portion 18b to the center mullion, and it is sufficient if at least one of them is adhered. Alternatively, the cover member 18 may be attached to the central mullion 15 by screwing together. After attaching the cover member 18 to the central mullion 15, as shown in FIG. 8 can be obscured.

By providing the cover member 18 around the upper end of the central mullion 15 as described above, the gap between the upper end of the central mullion 15 and the projection surface 13b of the upper frame 13 is prevented from being exposed to the outside. Therefore, it is possible to prevent the appearance quality from being impaired.

In addition, although he is trying to attach the cover member 18 to the mullion 15 in embodiment mentioned above, this invention is not limited to this. For example, as in the modification shown in FIG. can also be supported. In other words, the cover member 18A of the modified example extends in a direction orthogonal to both the finding cover portion 18b and the prospective cover portion 18a in addition to the finding cover portion 18b and the prospective cover portion 18a similar to those of the embodiment. The support wall portion 18c is molded integrally. In the cover member 18A of the modified example, a support wall portion 18c is provided so as to extend horizontally from the upper edge portion of the cover portion 18b. In the cover member 18 described above, for example, a double-sided tape is attached to the upper surface of the support wall portion 18c so that it can be attached to the projection surface 13b of the upper frame 13. As shown in FIG. In the modified example, the same reference numerals are assigned to the same configurations as in the embodiment.

Also in this modification, after the cover member 18A is provided around the upper end of the central mullion 15, as shown in FIG. Since it is possible to prevent the gap formed in the outer surface from being exposed to the outside, it is possible to prevent the appearance quality from being impaired. Moreover, in this modified example, since the object to be attached is the upper frame 13, the prospective cover portion 18a and the finding cover portion 18b of the cover member 18A can reliably contact the prospective surface 13b of the upper frame 13 without adjusting the mounting position. They are in contact with each other, facilitating the work of providing the cover member 18A. Further, there is no need to bring the prospective cover portion 18a and the finding cover portion 18b of the cover member 18A into contact with the prospective surface 15f and the prospective surface 15g of the central mullion 15, and accurate positioning is required when attaching the cover member 18A. It is possible to further simplify the work by, for example, not doing so. The support wall portion 18c does not necessarily have to protrude into the region surrounded by the prospective cover portion 18a and the finding cover portion 18b, and the support wall portion 18c may be provided so as to protrude outward.

In addition, although the mullion 15 having the mullion main body portion 15a and the mounting plate portion 15b is exemplified in the above-described embodiment and modification, the shape of the mullion is not limited to this. Also, as the cover member, one that covers the two surrounding surfaces of the central mullion is exemplified. can be added. As a result, even when the door 20 is removed, the gap between the upper end of the central mullion 15 and the prospective surface 13b of the upper frame 13 will not be exposed to the outside. Furthermore, although the upper frame 13 and the central mullion 15 are provided by using the sleeve wall 6 as a wall, the wall 1 is used as a wall and the upper frame 13 and the central mullion 15 are provided on one surface side thereof. It can also be applied to
