Description

[Technical Field]

[0001] The present disclosure relates to building materials. [Background technology]

[0002] Conventionally, there is known a fitting that includes a frame body and a shoji screen that is slidably disposed within the frame body. In the fitting, there is a fitting that includes a protruding rail structure having a lower frame with an upwardly protruding rail provided so as to protrude upward as a lower frame structure in order to guide the movement of the slidable shoji screen (for example, see Patent Document 1).

[0003] On the other hand, some building materials have a flat rail structure with a lower frame that reduces the amount of upward protrusion of the rail from the perspective of barrier-free access. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-109099 Summary of the Invention [Problem to be solved by the invention]

[0005] The rail structures of the lower frames are different between the protruding rail structure, which has a lower frame with an upwardly protruding rail, and the flat rail structure, which has a lower frame with a reduced amount of upward protrusion of the rail. Therefore, the lower frames are manufactured in separate facilities, which increases capital investment and ultimately leads to increased manufacturing costs. There is a need to reduce the manufacturing costs of the lower frames.

[0006] The present disclosure aims to provide building materials having a lower frame structure that can reduce manufacturing costs. [Means for solving the problem]

[0007] The present disclosure relates to a fixture comprising a lower frame and a lower frame attachment attached to the lower frame, wherein the lower frame is formed with an outdoor side upwardly protruding rail that is positioned on the outdoor side and protrudes upward, and an indoor side upwardly protruding rail that is positioned on the indoor side and protrudes upward, and the fixture comprises an indoor side height filler member that is positioned indoors relative to the indoor side upwardly protruding rail on the lower frame and has a height that fills in the height of the indoor side upwardly protruding rail, and an inter-rail height filler member that is positioned between the outdoor side upwardly protruding rail and the indoor side upwardly protruding rail on the lower frame and has a height that fills in the height of the outdoor side upwardly protruding rail and the indoor side upwardly protruding rail.

[0009] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. A sliding window 1 constituting the fitting of this embodiment will be described. In this embodiment, the lower frame structure of the lower frame 22 can be used for both a protruding rail structure 10 (see FIG. 4) in which the exterior rail 221 and the interior rail 222 protrude upward, and a flat rail structure 10A (see FIG. 6) in which a lower frame attachment 6 is attached to the lower frame 22.

[0010] First, we will explain the case where, in a sliding window 1 (door and window fixture), a lower frame attachment 6 is not attached to the lower frame 22, and the lower frame structure in the lower frame 22 has the outdoor rail 221 and the indoor rail 222 protruding upward to form a protruding rail structure 10.

[0011] In this specification, "visible direction" refers to the face direction of the panel materials 35, 45 of the sliding window 1 placed in an opening formed in the wall of a building, and "visible direction" refers to the thickness direction (i.e., the depth direction) of the panel materials 35, 45. "Visible direction" also refers to the indoor / outdoor direction. "Visible surface" refers to the surface of the sliding window 1 facing the outside and inside of the room, and "visible surface" refers to the surface of the sliding window 1 extending in the indoor / outdoor direction. In the drawings, the outside side of the sliding window 1 is referred to as the outside side X1, and the inside side of the sliding window 1 is referred to as the inside side X2.

[0012] As shown in Figures 1 to 3, a sliding window 1 is made up of a frame 2 attached to an opening in a building frame (not shown), and two shoji screens, an outer shoji screen 3 placed on the outside X1 and an inner shoji screen 4 placed on the inside X2, fitted inside the frame 2, as well as one screen 51 placed on the outside X1 of the outer shoji screen 3. The outer shoji screen 3 and inner shoji screen 4 can slide left and right (horizontally) within the frame 2 in the viewing direction.

[0013] The frame body 2 is formed by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24 in a rectangular shape. As shown in Figure 2, the upper frame 21 is provided with an outdoor rail 211 (a downwardly protruding rail) and an indoor rail 212 (a downwardly protruding rail). The upper frame 21 has a screen door rail 213 on the outdoor side of the outdoor rail 211. The lower frame 22 is provided with an outdoor rail 221 (an outdoor rail that protrudes upward) and an indoor rail 222 (an indoor rail that protrudes upward). The lower frame 22 has a screen door rail 223 on the outdoor side X1 of the outdoor rail 221.

[0014] In the lower frame 22, the outdoor rail 221 is disposed on the outdoor side of the lower frame 22 and protrudes upward. The indoor rail 222 is disposed on the indoor side X2 of the lower frame 22 and protrudes upward.

[0015] The screen door 51 is engaged with the screen door rails 213, 223 of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction.

[0016] The configuration of the frame 2 will be described in more detail. As shown in Fig. 2, the upper frame 21 has a composite structure in which resin cover materials 215, 216 are attached to the inner surface of a metal frame 214, which is the frame body. This provides excellent heat insulation and moisture resistance.

[0017] The resin cover material 215 is disposed between the outdoor rail 211 and the indoor rail 212 of the upper frame 21. The resin cover material 216 is configured to include the indoor side X2 portion of the indoor rail 212 of the upper frame 21, and is provided from the indoor side surface of the indoor rail 212 to the inner surface of the metal frame 214. The resin cover material 216 has an angle portion 2161 that protrudes toward the indoor side X2 beyond the indoor side end portion 214a of the metal frame 214. The resin cover materials 215, 216 are provided over the entire length of the upper frame 21 in the extension direction.

[0018] As shown in Figure 4, the lower frame 22 has a composite structure in which resin cover materials 226, 227 are attached to the inner surfaces 251, 252 of the metal frame body 224, which is the frame body main body. This provides excellent thermal insulation and moisture resistance. The metal frame body 224 is divided into an outdoor metal frame body 2241 and an indoor metal frame body 2242 between the outdoor rail 221 and the indoor rail 222. The outdoor metal frame body 2241 and the indoor metal frame body 2242 are connected by a resin connecting material 2243.

[0019] 4, the resin cover material 226 is disposed on the inner surface 251 of the outdoor metal frame 2241, between the outdoor rail 221 and the indoor rail 222 of the lower frame 22. The resin cover material 227 is disposed on the inner surface 252 of the indoor metal frame 2242, closer to the indoor side X2 than the indoor rail 222 of the lower frame 22. The resin cover materials 226, 227 are provided over the entire length of the lower frame 22 in the extension direction.

[0020] The resin cover material 226 has a vertical cover portion 226a that extends along the upper portion of the indoor side surface 221a of the outdoor rail 221 and curves downwardly toward the indoor side at the lower side, a horizontal cover portion 226c that extends from the lower end of the vertical cover portion 226a toward the indoor side, an outdoor leg portion 226d that extends downward from the underside of the outdoor side X1 of the horizontal cover portion 226c, and an indoor leg portion 226e that extends downward from the underside of the indoor side X2 of the horizontal cover portion 226c.

[0021] The upper end 226b of the vertical cover portion 226a abuts against the upper part of the outdoor rail 221 from the indoor side X2. The upper end 221b of the outdoor rail 221 protrudes slightly toward the indoor side X2. The outdoor leg portion 226d and the indoor leg portion 226e are placed on the inner surface 251 of the outdoor metal frame 2241 on the indoor side X2.

[0022] An engagement groove 224a opening toward the outdoor side X1 is provided on the inner surface 251 of the outdoor metal frame 2241 near the resin connecting material 2243, over the entire length in the extension direction of the lower frame 22. The lower end 226f of the indoor side leg 226e engages with this engagement groove 224a from the outdoor side X1.

[0023] The resin cover material 227 has a vertical cover portion 227a that extends along the upper portion of the indoor side surface 222a of the indoor rail 222 and curves downwardly toward the indoor side at the lower side, a horizontal cover portion 227c that extends integrally from the lower end of the vertical cover portion 227a toward the indoor side, an intermediate leg portion 227d that extends downward from the underside of the horizontal cover portion 227c midway in the projection direction, and an engagement portion 227e that protrudes downward from the indoor side X2 end of the horizontal cover portion 227c.

[0024] An upper end 227b of the vertical cover portion 227a abuts against the upper portion of the indoor side rail 222 from the indoor side X2. An upper end 222b of the indoor side rail 222 protrudes slightly toward the indoor side. An intermediate leg portion 227d of the resin cover material 227 is placed on the inner surface 252 of the indoor side metal frame body 2242.

[0025] The indoor metal frame 2242 has, at the top of the indoor side X2, a standing wall portion 224b that extends upward approximately parallel to the indoor side rail 222. A groove portion 224c that opens upward is provided at the upper end of the standing wall portion 224b. An L-shaped angle portion 228 is attached to the groove portion 224c. The angle portion 228 is formed to protrude from the standing wall portion 224b toward the indoor side X2. An engaging portion 227e of the resin cover material 227 engages with a corner portion 224d at the lower end of the groove portion 224c on the outdoor side X1.

[0026] As shown in Figure 3, the vertical frame 23 arranged on the door edge side of the outer shoji screen 3 has a composite structure in which a resin cover material 232 is attached to the inner surface of a metal frame body 231, which is the frame body main body. Therefore, it has excellent heat insulation and moisture prevention properties. The resin cover material 232 is arranged on the inner surface of the vertical frame 23, closer to the room side X2 than the outer shoji screen 3 when it is closed. The resin cover material 232 has an angle portion 2321 that protrudes toward the room side X2 beyond the room side end 231a of the metal frame body 231. The resin cover material 232 is provided over the entire length of the vertical frame 23 in the extension direction.

[0027] As shown in Figure 3, the vertical frame 24 arranged on the door edge side of the inner shoji screen 4 has a composite structure in which a resin cover material 242 is attached to the inner surface of a metal frame body 241, which is the frame body main body. Therefore, it has excellent heat insulation and moisture prevention properties. The resin cover material 242 is arranged on the inner surface of the vertical frame 24, closer to the room side X2 than the inner shoji screen 4 when it is closed. The resin cover material 242 has an angle portion 2421 that protrudes toward the room side X2 beyond the room side end portion 241a of the metal frame body 241. The resin cover material 242 is provided over the entire length of the vertical frame 24 in the extension direction.

[0028] As shown in Figures 1 to 3, the outer shoji screen 3 is constructed by fitting a panel 35 made of three pieces of glass inside a rectangular frame body 30 consisting of an upper frame 31, a lower frame 32, a vertical frame 33 located on the door tip side, and an outer joining frame 34, which is a vertical frame located on the door tail side. The outer shoji screen 3 is engaged with the outdoor rails 211, 221 of the upper frame 21 and the lower frame 22 so that it can move left and right. The lower frame 32 of the outer shoji screen 3 is provided with a door roller 36 that rolls on the outdoor rail 221 of the lower frame 22.

[0029] The inner shoji screen 4 is constructed by fitting a panel 45 made of three pieces of glass inside a rectangular frame body 40 consisting of an upper frame 41, a lower frame 42, a vertical frame 43 located at the door tip, and an inner joining frame 44 located at the door tail. The inner shoji screen 4 is engaged with the interior rails 212, 222 of the upper frame 21 and the lower frame 22 so that it can move left and right. The lower frame 42 of the inner shoji screen 4 is provided with a door roller 46 that rolls on the interior rail 222 of the lower frame 22.

[0030] As shown in Figures 2 and 3, the upper frame 31, lower frame 32, vertical frame 33 and outer joining frame 34 of the outer shoji screen 3 each have a composite structure in which resin frame materials 312, 322, 332, 342 are attached to the indoor side X2 of metal frame materials 311, 321, 331, 341. The upper frame 41, lower frame 42, vertical frame 43 and inner joining frame 44 of the inner shoji screen 4 each have a composite structure in which resin frame materials 412, 422, 432, 442 are attached to the indoor side X2 of metal frame materials 411, 421, 431, 441. This gives the outer shoji screen 3 and inner shoji screen 4 excellent thermal insulation and moisture resistance.

[0031] As shown in Fig. 4, airtight materials 321b, 421b are attached to the inner surfaces of the outdoor lower end vertical walls 321a, 421a on the outdoor side X1 of the metal frame members 321, 421 of the lower frames 32, 42. The airtight materials 321b, 421b have mounting portions 321c, 421c and airtight fins 321d, 421d extending approximately horizontally from the mounting portions 321c, 421c to the indoor side X2. The airtight fins 321d, 421d are pressed in a deflected state against the outdoor side X1 surface 221c of the outdoor rail 221 or the outdoor side X1 surface 222c of the indoor rail 222.

[0032] Next, a description will be given of a case where a flat rail structure 10A is constructed as a lower frame structure in the lower frame 22 by attaching a lower frame attachment 6 to the lower frame 22. As shown in Figures 5 to 7, the flat rail structure 10A can be constructed by attaching a lower frame attachment 6 for the lower frame 22 to the upper part of the lower frame 22 of the protruding rail structure 10 described above.

[0033] When attaching the lower frame attachment 6 to the upper part of the lower frame 22, the resin cover materials 226, 227 are removed from the lower frame 22 from the state shown in Fig. 4. Then, as shown in Fig. 5, the lower frame attachment 6 is attached to the upper part of the lower frame 22. This allows for the formation of a flat rail structure 10A configured by attaching the lower frame attachment 6 to the lower frame 22, as shown in Figs. 6 and 7.

[0034] The outer shoji 3A and inner shoji 4A used in the flat rail structure 10A differ from the outer shoji 3 and inner shoji 4 used in the protruding rail structure mainly in the size of the door rollers 36, 46, 36A, 46A and in the absence of airtight materials 321b, 421b. Also, the structure of the outer shoji 3A and inner shoji 4A used in the flat rail structure 10A differs from the structure of the outer shoji 3 and inner shoji 4 used in the protruding rail structure 10.

[0035] The outer shoji 3A and inner shoji 4A used in the flat rail structure 10A will be described. As shown in Figure 6, the door roller 36A of the outer shoji 3A and the door roller 46A of the inner shoji 4A used in the flat rail structure 10A are wider in the prospective direction than the door roller 36 of the outer shoji 3 and the door roller 46 of the inner shoji 4 (see Figure 4) used in the protruding rail structure 10, and their lower ends are located lower.

[0036] Furthermore, the outer shoji screen 3A and the inner shoji screen 4A used in the flat rail structure 10A do not have the airtight materials 321b, 421b (see Fig. 4) used in the protruding rail structure 10, but have extension plates 321e, 421e extending downward from the lower ends of the outdoor lower end vertical walls 321a, 421a on the outdoor side X1 of the metal frame members 321, 421 of the lower frames 32, 42, as shown in Fig. 6. When the lower frame attachment 6 is attached to the lower frame 22, as shown in Fig. 7, airtight materials 713, 723 provided on the side portions of the outdoor side X1 of the outdoor rail cap member 71 and the indoor rail cap member 72 of the lower frame attachment 6, which will be described later, are pressed against the extension plates 321e, 421e.

[0037] The specific configuration of the lower frame attachment 6 will be described. As shown in Figures 5 and 6, the lower frame attachment 6 includes an exterior height filler member 61, an inter-rail height filler member 62, an interior height filler member 63, an exterior rail cap member 71, and an interior rail cap member 72. The exterior height filler member 61, the inter-rail height filler member 62, the interior height filler member 63, the exterior rail cap member 71, and the interior rail cap member 72 are provided over the entire length of the lower frame 22 in the extension direction.

[0038] 5 and 6, the outdoor height filler member 61 is disposed above the lower frame 22, on the outdoor side X1, higher than the outdoor rail 221, and attached to the lower frame 22. The outdoor height filler member 61 has a height that fills the height of the outdoor rail 221.

[0039] The outdoor height filling member 61 has a bottom fixed plate 611 extending horizontally, a downwardly open groove frame 612 that is open downward and is provided at the outdoor side end of the bottom fixed plate 611, a rising wall 613 that rises upward from the downwardly open groove frame 612, a downwardly extending plate 615 that extends downward from the outdoor side plate portion 612a of the downwardly open groove frame 612, and an outdoor side protruding open frame 616 that protrudes from the lower end of the outdoor side plate portion 612a of the downwardly open groove frame 612 toward the outdoor side X1 and is open upward.

[0040] The bottom fixing plate 611 is fixed by screws to the inner surface 253 of the outdoor side X1 of the outdoor metal frame body 2241 rather than to the outdoor side rail 221 of the bottom frame 22.

[0041] When the outdoor height filler member 61 is attached to the bottom frame 22, the downward open groove frame 612 engages with a screen door rail 223 that protrudes upward from the upper end of the outdoor side X1 end of the outdoor metal frame body 2241 of the bottom frame 22. The screen door rail 223 is the part that engages with the lower end of the screen door 51 (see Figure 2) when the bottom frame 22 is used as the protruding rail structure 10 without attaching the bottom frame attachment 6 to the bottom frame 22.

[0042] An L-shaped piece 614 that protrudes toward the indoor side X2 and opens upward is formed midway along the rising wall 613. An upper end 613a of the rising wall 613 engages with the lower end of the screen door 51 (see FIG. 2).

[0043] 5 and 6, the rail-to-rail height filling member 62 is disposed at the top of the lower frame 22, between the outdoor rail 221 and the indoor rail 222 in the indoor-outdoor direction, and is attached to the lower frame 22. The rail-to-rail height filling member 62 has a height that fills the height of the outdoor rail 221 and the indoor rail 222.

[0044] The rail-gap height filler member 62 is integrally formed by combining and engaging a lower member 621, which is disposed below and has a generally E-shape that opens upward, with an upper member 622, which is disposed above the lower member 621 and has a generally E-shape that opens downward. As shown in FIG. 6 , the lower member 621 is screwed to the inner surface 251 of the indoor side X2, rather than the outdoor rail 221 that protrudes from the upper surface of the outdoor metal frame body 2241 of the bottom frame 22. The upper member 622 is fitted into the upper member 622 that is screwed to the bottom frame 22. Therefore, the upper member 622 can be fitted in after the upper member 622 is screwed to the bottom frame 22, which provides excellent attachability for the rail-gap height filler member 62 when attached to the bottom frame 22.

[0045] 5 and 6, the indoor height filler member 63 is positioned at the top of the lower frame 22, on the indoor side X2 of the indoor rail 222, and is attached to the lower frame 22. The indoor height filler member 63 is formed in a frame shape that is open at the bottom. The indoor height filler member 63 has a height that fills the height of the indoor rail 222.

[0046] The outdoor height filler member 61, the rail-to-rail height filler member 62, and the indoor height filler member 63 are each configured to be detachably attached to the lower frame 22. For example, as shown in FIG. 8 , the outdoor height filler member 61, the rail-to-rail height filler member 62, and the indoor height filler member 63 can each have caps 61a, 62a, and 63a attached to both longitudinal ends, and handles 61b, 62b, and 63b provided on the caps 61a, 62a, and 63a. In this case, the outdoor height filler member 61, the rail-to-rail height filler member 62, and the indoor height filler member 63 can be easily attached to and detached from the lower frame 22 by hooking onto the handles 61b, 62b, and 63b of the caps 61a, 62a, and 63a. Note that, although the caps 61a, 62a, and 63a are attached to both longitudinal ends of the outdoor height filler member 61, the rail-to-rail height filler member 62, and the indoor height filler member 63, the present invention is not limited thereto. The caps 61a, 62a, 63a may be attached to only one of the longitudinal ends of the outdoor height filler member 61, the rail-to-rail height filler member 62, and the indoor height filler member 63.

[0047] The exterior rail cap member 71 is attached to the upper end 221b of the exterior rail 221. The exterior rail cap member 71 has a running surface 711 formed on the upper part along which the rollers 36A of the exterior shoji screen 3A run, an engagement portion 712 formed on the lower part of the running surface 711, and an airtight material 713 provided on the side of the exterior side X1. The running surface 711 is formed in a curved shape that convex upward and extends in the left-right direction. The engagement portion 712 is attached by engaging with the upper end 221b of the exterior rail 221. The airtight material 713 is pressed against the surface of the interior side X2 of the extension plate 321e that extends downward from the exterior lower end vertical wall 321a of the exterior side X1 of the metal frame member 321 of the lower frame 32.

[0048] The indoor rail cap member 72 is attached to the upper end 222b of the indoor rail 222. The indoor rail cap member 72 has a running surface 721 formed on the upper part along which the door roller 46A of the inner shoji screen 4A runs, an engagement portion 722 formed on the lower part of the running surface 721, and an airtight material 723 provided on the side of the outdoor side X1. The running surface 721 is formed in a curved shape that convex upward and extends in the left-right direction. The engagement portion 722 is attached by engaging with the upper end 222b of the indoor rail 222. The airtight material 723 is pressed against the indoor side X2 surface of the extension plate 421e that extends downward from the outdoor lower end vertical wall 421a on the outdoor side X1 of the metal frame member 421 of the lower frame 42.

[0049] Here, different shapes are used for the door roller 36A in the flat rail structure 10A and the door roller 36 in the protruding rail structure 10. On the other hand, in both the protruding rail structure 10 and the flat rail structure 10A, the processed shape of the lower end cutout portion 331a formed at the lower end of the metal stile 331 of the vertical stile 33 arranged on the door tip side is the same, as shown in Figure 9.

[0050] For example, for the vertical stile 33 arranged on the door end side, as shown in Fig. 10, a vertical stile 33 having a lower end cutout 331a is used in the protruding rail structure 10. In the protruding rail structure 10, the metal stile material 331 of the vertical stile 33 arranged on the door end side has a lower end cutout 331a formed at the lower end to avoid the exterior rail 221 so that the lower end of the door roller 36 can roll on the exterior rail 221.

[0051] 11, the flat rail structure 10A uses a vertical stile 33 with a lower end cutout 331a for the vertical stile 33 arranged on the door edge side, similar to the protruding rail structure 10. In the flat rail structure 10A, the metal stile 331 of the vertical stile 33 arranged on the door edge side is arranged so that the lower end of the door roller 36A can roll on the outdoor rail 221, and the lower end of the door roller 36A is arranged to protrude downward from the metal stile 331 of the vertical stile 33 arranged on the door edge side.

[0052] This allows the flat rail structure 10A and the protruding rail structure 10 to share the same cutout processing for the lower end cutout portion 331a of the vertical stile 33 located on the door edge side. This allows the factory equipment to be shared, thereby reducing manufacturing costs.

[0053] Next, a procedure for forming the flat rail structure 10A by attaching the lower frame attachment 6 to the lower frame 22 of the protruding rail structure 10 will be described. When attaching the lower frame attachment 6 to the lower frame 22 of the protruding rail structure 10, the resin cover materials 226, 227 are removed from the lower frame 22 in the state shown in FIG.

[0054] Then, as shown in Figure 5, lower frame attachments 6 (outdoor height filler members 61, rail-to-rail height filler members 62, indoor height filler members 63, outdoor rail cap members 71, indoor rail cap members 72) are attached to the upper part of the lower frame 22. In this way, as shown in Figures 6 and 7, by attaching the lower frame attachments 6 to the lower frame 22 of the protruding rail structure 10, a flat rail structure 10A can be constructed.

[0055] In this way, the lower frame 22 can be used in common for both the protruding rail structure 10, in which the outdoor rail 221 and the indoor rail 222 protrude upward, and the flat rail structure 10A, in which the lower frame attachment 6 is attached to the lower frame 22. Therefore, the lower frame 22 can be used in common, which reduces manufacturing costs.

[0056] According to this embodiment, the following effects are achieved: The sill attachment 6 of this embodiment is a sill attachment 6 for the sill 22 of a sliding window 1, and the sill 22 is formed with an exterior rail 221 that is arranged on the exterior side of the room and protrudes upward, and an interior rail 222 that is arranged on the interior side X2 and protrudes upward, and is equipped with an interior height filler member 63 that is arranged on the interior side of the interior rail 222 in the sill 22 and has a height that fills up the height of the interior rail 222, and an inter-rail height filler member 62 that is arranged between the exterior rail 221 and the interior rail 222 in the sill 22 and has a height that fills up the height of the exterior rail 221 and the interior rail 222.

[0057] As a result, a flat rail structure 10A can be created simply by attaching the lower frame attachment 6 to the lower frame 22 used in the protruding rail structure 10. This allows the lower frame 22 to be shared, thereby reducing manufacturing costs. Furthermore, the indoor height filler members 63 and the inter-rail height filler members 62 fill the height of the outdoor rail 221 and the indoor rail 222, improving cleanability. Furthermore, the indoor height filler members 63 and the inter-rail height filler members 62 fill the height of the outdoor rail 221 and the indoor rail 222, eliminating steps and preventing people from falling over steps when passing through wheelchairs.

[0058] In this embodiment, the device comprises an outdoor rail cap member 71 attached to the upper end 221b of the outdoor rail 221, and an indoor rail cap member 72 attached to the upper end 222b of the indoor rail 222. The outdoor rail cap member 71 and the indoor rail cap member 72 form a running surface that corresponds to the shape of the door rollers 36A, 46A, making it possible to easily accommodate door rollers of various shapes.

[0059] In this embodiment, the lower frame 22 includes an exterior height filler member 61 that is positioned on the exterior side X1 of the exterior rail 221 and has a height that fills the height of the exterior rail 221. This makes it possible to configure a flat rail structure with a small amount of upward protrusion over a wide range in the projection direction of the lower frame 22. Therefore, by configuring a flat rail structure over a wider range in the projection direction of the lower frame 22, a more preferable barrier-free structure can be realized. Furthermore, the exterior height filler member 61 fills the height of the exterior rail 221, and the interior height filler member 63, the inter-rail height filler member 62, and the exterior height filler member 61 prevent steps from being formed, which further prevents people from falling over steps when passing through a wheelchair.

[0060] The outdoor height filler members 61, the rail-to-rail height filler members 62, and the indoor height filler members 63 are each detachable from the lower frame 22. Therefore, by attaching and detaching the lower frame attachments 6 to and from the lower frame 22, the lower frame structure can easily be configured as either a protruding rail structure 10 or a flat rail structure 10A.

[0061] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate. [Explanation of symbols]
