Description

[Technical field]

[0001] The present invention relates to a mounting structure for a mullion provided in a wall such as a sleeve wall. [Background technology]

[0002] For example, in a single-sided sliding door in which a door body is movably disposed along one surface of a sleeve wall, a mullion is provided along the edge of the sleeve wall (see, for example, Patent Document 1). The mullion is provided between the visible surface on the inner periphery of the upper frame and the visible surface of the lower frame, or between the floorboard. A sliding door provided with a mullion has the advantage that it can prevent light from leaking through the gap between the door body and the sleeve wall. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-226313 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the case of sliding door frames with large widths, the frame materials are sometimes not connected to each other in advance, but are fixed to the frame separately. In this case, due to dimensional tolerances and construction errors, the middle mullion, which is placed between the upper and lower frames or floorboards, may not be able to be placed between the upper and lower frames, or conversely, a gap may be created between the upper frame and the projected surface. For this reason, it is necessary to cut the middle mullion on-site to adjust its length or to reset the position of the upper frame, which makes the assembly work more complicated.

[0005] In view of the above-mentioned circumstances, the present invention has an object to provide a mounting structure for a mullion that can prevent a situation in which the appearance quality is impaired without complicating the assembly work. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, the mounting structure for a middle mullion of the present invention is a mounting structure for a middle mullion arranged along the edge of a wall from the projected surface of an upper frame arranged on one surface side of the wall, characterized in that the middle mullion is supported on one surface of the wall and a cover member is provided around the upper end of the middle mullion so as to protrude from the upper end of the middle mullion. Effect of the Invention

[0007] According to the present invention, a cover member is provided at the upper end of the middle mullion, which prevents a situation in which the dimensions of the middle mullion are set short and it cannot be placed between the upper frame and the lower frame, etc., and after the middle mullion is installed, the gap that occurs between it and the projected surface of the upper frame can be covered with the cover member, making it possible to prevent a situation in which the appearance quality is impaired without complicating the assembly work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A preferred embodiment of the mounting structure for a central mullion according to the present invention will be described in detail below with reference to the attached drawings. For convenience, the terms "prospect direction" and "visible direction" may be used below. The "prospect direction" is the direction along the depth of the fitting, as shown by arrow A in the figure. A surface along the prospective direction may be called a "prospect surface." The "prospect direction" is the direction along the top and bottom perpendicular to the prospective direction in the case of an object that extends along the horizontal direction, such as an upper frame. In the case of an object that extends along the vertical direction, such as a vertical frame, the direction along the horizontal direction perpendicular to the prospective direction is called the "prospect direction." A surface along the prospective direction may be called a "prospect surface."

[0010] 1 to 4 show a fitting to which a central mullion mounting structure according to an embodiment of the present invention is applied. The fitting illustrated here is called an indoor single sliding door, in which a single door body 20 is movably arranged inside a frame body 10. A rectangular opening area 5 surrounded by left and right pillars 2, 3 and a lintel 4 is formed in a wall 1 of a structure on which the fitting is to be installed. In this opening area 5, the mutual distance between the left and right pillars 2, 3 is set to be shorter than twice the dimension along the left and right of the door body 20. Inside the opening area 5, a sleeve wall 6 (wall body) is provided so as to continue from one of the pillars 2. The sleeve wall 6 is formed by arranging an interior material 8 on the surface of a base material 7, and has a dimension in the forward direction smaller than that of the wall 1, and is large enough to cover the majority of the opening area 5. In this embodiment, in FIG. 4, if the lower side of the wall 1 is Room A and the upper side of the wall 1 is Room B, the interior material 8 of Room B faces the surface of the base material 7 of the sleeve wall 6 facing Room B, and the wall 1 and the sleeve wall 6 are located on the same plane. Between the sleeve wall 6 and the other pillar 3, a passage opening (opening) 9 that communicates between Room A and Room B and can be closed by the door body 20 is secured. As described above, since the mutual distance between the pillars 2, 3 is configured to be shorter than twice the door body 20, the edge portion located on the passage opening 9 side on the surface of the sleeve wall 6 facing Room A is always covered by the door body 20 regardless of the opening and closing position of the door body 20. The base material 7 of the sleeve wall 6 is provided with the interior material 8 so as to cover the surface on the inner periphery side of the passage opening 9 and the surface facing Room A. Reference numeral 8a in the figure denotes a baseboard provided on the lower edge of the interior material 8.

[0011] The frame 10 is provided with an upper frame 13 between the upper ends of the left and right vertical frames 11, 12, and a lower rail 14 between the lower ends of the vertical frames 11, 12, and is disposed in the opening area 5 of the wall 1 on the A room side of the sleeve wall 6. That is, in this fitting, the frame 10 is disposed on the surface side of the sleeve wall 6 facing the A room. The vertical frames 11, 12, the upper frame 13, and the lower rail 14 are extruded shapes formed from metals such as aluminum alloys or resins, and are configured so that the entire length along the longitudinal direction has a uniform cross-sectional shape. In the illustrated example, the vertical frames 11, 12 and the upper frame 13 are provided with the inner peripheral edge located on the A room side, and the projecting fins 11a, 12a, and 13a extending in the projecting direction toward the A room are applied. These vertical frames 11, 12 and upper frame 13 are almost covered by the interior material 8 of Room A, which covers the surface of wall 1, extended up to a position where it abuts the projecting fin portions 11a, 12a, 13a, so that only the protruding edges of the projecting fin portions 11a, 12a, 13a are visible from the Room A side.

[0012] In addition, the frame body 10 is provided with a middle mullion 15 between the front surface 13b on the inner periphery side of the upper frame 13 and the floor board 30. The middle mullion 15 is an extruded shape formed from metal such as aluminum alloy or resin, similar to the vertical frames 11 and 12, and is configured so that the entire length along the longitudinal direction has a uniform cross-sectional shape. In this embodiment, as shown in FIG. 5, a middle mullion 15 having a mullion main body 15a and a mounting plate 15b is exemplified. The mullion main body 15a is a hollow square tube configured so that the dimension along the left-right direction is larger than the dimension along the front direction. The mohair 16 is attached to the front surface of the mullion main body 15a facing the A room through a mounting groove 15c at the approximately central part. The mounting plate 15b is a flat plate extending in the front direction, and has support plates 15d and 15e along the front direction at both side edges. The mounting plate portion 15b is molded integrally with the upright body portion 15a, with one support plate portion 15d connected to a corner of the upright body portion 15a that is on the outer periphery side of the passage opening 9. The other support plate portion 15e of the mounting plate portion 15b extends to the facing surface of the upright body portion 15a facing the A room, and detachably supports a cap member 17 between the mounting plate portion 15b and the upright body portion 15a. The cap member 17 is for covering the screw S (see FIG. 6) screwed into the mounting plate portion 15b.

[0013] As shown in Figures 4 and 6(a), the above-mentioned middle mullion 15 is placed between the inner peripheral surface 13b of the upper frame 13 and the upper surface of the floorboard 30 after the vertical frames 11, 12 and upper frame 13 are attached to the wall 1, and by screwing screws S into the base material 7 of the sleeve wall 6 via the mounting plate portion 15b, it is arranged vertically along the edge of the surface of the sleeve wall 6 facing Room A, as shown in Figures 4 and 6(b). The middle mullion 15 supported by the sleeve wall 6 has a dimension set along the visible direction so that a part of the mullion main body portion 15a protrudes further toward the inner peripheral side of the passage opening 9 than the interior material 8, and is always covered by the door body 20 from the Room A side, regardless of the open / closed position of the door body 20.

[0014] On the other hand, as is clear from Figure 6(b), the dimension along the length of the middle mullion 15 is set to be smaller than the distance from the visible surface 13b of the upper frame 13 to the upper surface of the floorboard 30. Therefore, when the middle mullion 15 is supported by the sleeve wall 6, it can be easily and reliably positioned between the upper frame 13 and the floorboard 30, and there is no need to cut the middle mullion 15 on-site to adjust its length.

[0015] However, the lower end of the middle mullion 15 supported by the sleeve wall 6 abuts on the upper surface of the floorboard 30, while a gap is generated between the upper end and the visible surface 13b of the upper frame 13. This gap is visible from the B room side and the inner circumference side of the passage opening 9 even when the base material 7 of the sleeve wall 6 is covered with the interior material 8. For this reason, a cover member 18 is provided for this fitting to cover the mullion main body part 15a of the middle mullion 15. As shown in Figs. 5 and 7, the cover member 18 has a visible cover part 18a and a visible cover part 18b. The visible cover part 18a is a rectangle having a size large enough to cover the entire surface of the visible surface 15f, which is the inner circumference side of the passage opening 9, at the upper end of the mullion main body part 15a. The visible cover part 18a is a rectangle having a size large enough to cover the entire surface of the visible surface 15g facing the B room at the upper end of the mullion main body part 15a. The cover member 18 may be made of metal or resin. In the present embodiment, the cover member 18 is made of stainless steel (SUS) and formed into a thin plate.

[0016] As shown in Fig. 8(a) and Fig. 8(b), the cover member 18 is attached to the upper end of the middle mullion 15 in a state where it protrudes from the upper end of the middle mullion 15 before the interior material 8 is attached to the sleeve wall 6 after the middle mullion 15 is supported by the base material 7 of the sleeve wall 6. The method of attaching the cover member 18 to the middle mullion 15 is to attach the cover member 18 to the surface of the middle mullion 15 with double-sided tape. In this case, it is not necessary to attach both the visible cover portion 18a and the visible cover portion 18b to the middle mullion, and it is sufficient if at least one of them is attached. The cover member 18 may also be attached to the middle mullion 15 by screwing in a screw. After the cover member 18 is attached to the middle mullion 15, if the interior material 8 is arranged on the base material 7 of the sleeve wall 6 as shown in Fig. 8(c), a part of the cover member 18 can be covered and hidden by the interior material 8.

[0017] By providing a cover member 18 around the upper end of the middle mullion 15 as described above, it is possible to prevent the gap that occurs between the upper end of the middle mullion 15 and the visible surface 13b of the upper frame 13 from being exposed to the outside, thereby making it possible to prevent the appearance quality from being impaired.

[0018] In the above embodiment, the cover member 18 is attached to the middle mullion 15, but the present invention is not limited thereto. For example, as shown in FIG. 9, if a cover member 18A having a support wall portion 18c in addition to the visible cover portion 18a and the visible cover portion 18b is applied, the cover member 18 can be supported on the visible surface 13b of the upper frame 13. That is, the cover member 18A of the modified example is formed integrally with the visible cover portion 18b and the visible cover portion 18a as in the embodiment, and the support wall portion 18c extending in a direction perpendicular to both the visible cover portion 18b and the visible cover portion 18a. In the cover member 18A of the modified example, the support wall portion 18c is provided so as to extend horizontally from the upper edge portion of the visible cover portion 18b. In the above-mentioned cover member 18, for example, a double-sided tape is attached to the upper surface of the support wall portion 18c, and the cover member 18 can be attached to the visible surface 13b of the upper frame 13. In the modified example, the same reference numerals are used for the same configurations as those in the embodiment.

[0019] Even in this modified example, after the cover member 18A is provided around the upper end of the middle mullion 15, as shown in FIG. 9(b), the gap between the upper end of the middle mullion 15 and the visible surface 13b of the upper frame 13 is prevented from being exposed to the outside, so that the appearance quality is prevented from being impaired. Moreover, in this modified example, since the attachment target is the upper frame 13, the visible cover portion 18a and the visible cover portion 18b of the cover member 18A are surely in contact with the visible surface 13b of the upper frame 13 without adjusting the attachment position, which makes it easier to attach the cover member 18A. Furthermore, there is no need to abut the visible cover portion 18a and the visible cover portion 18b of the cover member 18A against the visible surface 15f and the visible surface 15g of the middle mullion 15, and therefore accurate alignment is not required when attaching the cover member 18A, making the work even easier. The support wall portion 18c does not necessarily have to protrude into the area surrounded by the front cover portion 18a and the front cover portion 18b, and the support wall portion 18c may be provided so as to protrude outward.

[0020] In the above-mentioned embodiment and modified example, the middle mullion 15 having the mullion body part 15a and the mounting plate part 15b is exemplified, but the shape of the middle mullion is not limited to this. In addition, the cover member is exemplified as one that covers two peripheral surfaces of the middle mullion, but for example, a sight cover part may be added to the cover member 18 of the embodiment so as to cover the sight surface facing the A room. This eliminates the risk of the gap between the upper end of the middle mullion 15 and the sight surface 13b of the upper frame 13 being exposed to the outside even when the door body 20 is removed. Furthermore, the sleeve wall 6 is exemplified as a wall body and the upper frame 13 and the middle mullion 15 are provided, but it is also possible to apply it to a wall 1 as a wall body and the upper frame 13 and the middle mullion 15 are provided on one surface side of the wall 1.

[0021] As described above, the mounting structure for a middle mullion of the present invention is a mounting structure for a middle mullion arranged along the edge of a wall from the projected surface of an upper frame arranged on one surface side of the wall, and is characterized in that the middle mullion is supported on one surface of the wall and a cover member is provided around the upper end of the middle mullion so as to protrude from the upper end of the middle mullion. According to this invention, a cover member is provided at the upper end of the middle mullion, which prevents a situation in which the dimensions of the middle mullion are set short and it cannot be placed between the upper frame and the lower frame, etc., and after the middle mullion is installed, the gap that occurs between it and the projected surface of the upper frame can be covered with the cover member, making it possible to prevent a situation in which the appearance quality is impaired without complicating the assembly work.

[0022] The present invention is also characterized in that, in the above-mentioned mounting structure for the middle mullion, the upper frame guides the door body movably along one surface of the wall body, and the cover member is provided with a visible cover portion which covers the visible surface facing the inner periphery of the opening in the middle mullion which is opened and closed by the door body, and a visible cover portion which covers the visible surface on the side opposite to one surface of the wall body. According to this invention, the face of the middle mullion facing the door body is covered by the door body, so it is not exposed to the outside during normal use. Therefore, if a cover member having a concealed cover part and a concealed cover part is prepared, it is possible to prevent the gap from being exposed and reduce manufacturing costs.

[0023] The present invention is also characterized in that, in the above-mentioned mounting structure for the mullion, the cover member is attached to the mullion. According to this invention, the operation of attaching the cover member can be facilitated.

[0024] Furthermore, the present invention is characterized in that in the above-mentioned mounting structure for the mullion, the cover member is attached to the upper frame. According to this invention, since the cover member is supported by the upper frame, it is possible to reliably cover any gap that occurs between the cover member and the projected surface of the upper frame without adjusting the mounting position of the cover member.
