Description

[Technical Field]

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

[0002] Conventionally, there has been known a sliding window in which an outer shoji screen and an inner shoji screen are placed inside the frame so that they can move left and right (see, for example, Patent Document 1). The outer shoji screen and the inner shoji screen of the sliding window are placed in the closed position by overlapping the outer mating frame of the outer shoji screen and the inner mating frame of the inner shoji screen in the indoor / outdoor direction at the center of the window.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-109099 Summary of the Invention [Problem to be solved by the invention]

[0004] In order to seal the gap between the outer and inner stiles that overlap in the closed position, a fin member made of a soft material is provided on the exterior facing surface of the inner stile, which comes into contact with the interior facing surface of the outer stile.

[0005] However, because anti-vibration components are located at the top and bottom ends of the inner stile, it is necessary to avoid interference with the anti-vibration components when installing the fin members. In this case, in order to reliably seal the gap between the inner and outer stiles, it is necessary to install separate fin members on the anti-vibration components, which may increase the manufacturing costs of the shoji screen.

[0006] The outer stile is provided with a crescent receiver that engages with the crescent lock provided on the inner stile. To prevent interference between the fin member and the crescent receiver when the inner screen opens and closes, the portion of the fin member that corresponds to the crescent receiver must be cut out.

[0007] Therefore, the inventor has discovered the problem of how to easily seal the gap between the inner and outer stiles that overlap in the closed position using fin members. [Means for solving the problem]

[0008] The building fixtures disclosed herein comprise a frame body that is attached to an opening in the building's main body, and an inner shoji screen and an outer shoji screen that are movably stored inside the frame body in the left-right direction, the inner shoji screen and the outer shoji screen having an inner joining frame and an outer joining frame that overlap in the indoor-outdoor direction when placed in the closed position, and the outer joining frame has a fin member that protrudes from its visible surface on the indoor side toward the visible surface on the outdoor side of the inner joining frame.

[0010] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. The fittings of this embodiment are shown as a sliding window 1. As shown in Figures 1, 2 and 3, the sliding window 1 is constructed by fitting an inner shoji screen 3 on the indoor side, an outer shoji screen 4 on the outdoor side, and a screen door 5 inside a frame 2 attached to an opening in a building skeleton so that they can move left and right. The frame 2 is constructed 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. In Figures 2 to 5, X1 indicates the outdoor side of the sliding window 1, and X2 indicates the indoor side of the sliding window 1.

[0011] The inner shoji screen 3 is constructed with two panes of glass 35 placed via a spacer 36 inside a rectangular frame body 30 consisting of an upper frame 31, a lower frame 32, a vertical frame 33 at the leading edge, and an inner meeting frame 34 at the trailing edge. As shown in Figure 1, the inner shoji screen 3 has a vertically-mounted structure in which both ends of the upper frame 31 and the lower frame 32 are attached to the inside of the vertical frame 33 and the inner meeting frame 34, respectively. As shown in Figure 2, the inner shoji screen 3 is movably engaged with interior rails 211 and 221 provided on the upper frame 21 and the lower frame 22, respectively. The lower frame 32 of the inner shoji screen 3 is provided with a door roller 37 that moves along the interior rails 211 and 221. Furthermore, as shown in Figure 1, the inner meeting frame 34 of the inner shoji screen 3 is provided with a crescent lock 38.

[0012] The outer shoji screen 4 is constructed with two panes of glass 45 placed via spacers 46 inside a rectangular frame body 40 consisting of an upper frame 41, a lower frame 42, a vertical frame 43 at the door tip, and an outer meeting frame 44 at the door tail. As shown in Figure 1, the outer shoji screen 4 has a vertically-mounted structure in which both ends of the upper frame 41 and the lower frame 42 are attached to the inside of the vertical frame 43 and the outer meeting frame 44, respectively. As shown in Figure 2, the outer shoji screen 4 is engaged with the exterior rails 212, 222 provided on the upper frame 21 and the lower frame 22, respectively, so that it can move left and right. The lower frame 42 of the outer shoji screen 4 is provided with a door roller 47 that moves along the exterior rails 212, 222. Furthermore, as shown in Figure 5, the inner frame 44 of the outer screen 4 is provided with a crescent receiver 48 that can engage with the crescent lock 38.

[0013] As shown in Figures 2 and 3, the upper frame 31, lower frame 32, vertical frame 33, and inner joining frame 34 of the inner shoji screen 3 each have a composite structure in which resin cover materials 312, 322, 332, and 342 are attached to the indoor side of metal frame materials 311, 321, 331, and 341. The upper frame 41, lower frame 42, vertical frame 43, and outer joining frame 44 of the outer shoji screen 4 each have a composite structure in which resin cover materials 412, 422, 432, and 442 are attached to the indoor side of metal frame materials 411, 421, 431, and 441. This gives the inner shoji screen 3 and outer shoji screen 4 excellent insulation and moisture resistance.

[0014] 2 and 3, the screen door 5 is disposed on the exterior side of the outer shoji screen 4. The screen door 5 is engaged with the screen door rails 213, 223 disposed on the exterior-most sides of the upper frame 21 and the lower frame 22, respectively, so as to be movable in the left-right direction.

[0015] Next, the sealing structure between the inner door frame 34 of the inner door screen 3 and the outer door frame 44 of the outer door screen 4 will be explained using Figures 3, 4 and 5. When the inner door screen 3 and the outer door screen 4 are arranged in the closed position as shown in Figure 3, the inner door frame 34 of the inner door screen 3 and the outer door frame 44 of the outer door screen 4 are arranged so that they overlap each other in the indoor / outdoor direction at the center of the left-right direction of the sliding window 1.

[0016] A gasket 443 made of a soft material is attached to the interior facing surface 441a of the metal frame material 441 of the exterior meeting frame 44 of the exterior shoji screen 4, outside the exterior extension piece 4411, i.e., on the vertical frame 24 side. The gasket 443 is provided over the entire length of the metal frame material 441 in the extension direction and protrudes toward the interior side of the room. When the interior shoji screen 3 and the exterior shoji screen 4 are positioned in the closed position, the gasket 443 elastically contacts the interior meeting frame 34 of the interior shoji screen 3. As a result, the gasket 443 seals the gap between the interior meeting frame 34 and the exterior meeting frame 44 at the outermost part of the exterior shoji screen 4, reducing the intrusion of wind from outside the room.

[0017] An inner extension piece 3411 is provided on the outdoor facing surface 341a of the metal frame member 341 of the inner joining frame 34, over the entire length in the extension direction of the metal frame member 341. The inner extension piece 3411 is formed by extending the outdoor facing surface 341a of the metal frame member 341 in the facing direction toward the vertical frame 24. This forms a storage space S1 inside the inner extension piece 3411 that opens toward the vertical frame 24.

[0018] An outer extension piece 4411 is provided on the indoor-facing surface 441a of the metal frame material 441 of the outer joining frame 44 so as to protrude from the metal frame material 441 toward the indoor side. The outer extension piece 4411 is formed in an L shape with its tip facing the vertical frame 23. This forms a storage space S2 inside the outer extension piece 4411 that opens toward the vertical frame 23.

[0019] When the inner sash 3 and the outer sash 4 are arranged in the closed position, the inner extension piece 3411 of the inner interlocking frame 34 is arranged to be housed in the storage space S2 inside the outer extension piece 4411 of the outer interlocking frame 44, and the outer extension piece 4411 of the outer interlocking frame 44 is arranged to be housed in the storage space S1 inside the inner extension piece 3411 of the inner interlocking frame 34. This forms a labyrinth between the inner interlocking frame 34 and the outer interlocking frame 44, further reducing the intrusion of wind from outside the room.

[0020] The resin cover material 442 of the outer joining frame 44 is attached to the inside of the metal frame material 441, i.e., to the end on the vertical frame 23 side, over the entire length of the outer joining frame 44 in the extension direction. A fin member 444 made of a soft material is provided on the indoor-facing surface 442a of this resin cover material 442. The fin member 444 is provided over the entire length of the resin cover material 442 in the extension direction and protrudes toward the outdoor-facing surface 342a of the resin cover material 342 of the inner joining frame 34. The fin member 444 of this embodiment is adhered to the resin cover material 442.

[0021] The fin member 444 elastically contacts the inner meeting frame 34 of the inner sash 3 when the inner sash 3 and the outer sash 4 are arranged in the closed position. Specifically, the fin member 444 is arranged so as to elastically contact the outdoor facing surface 342a of the resin cover material 342 which is arranged flush with the outdoor facing surface 341a of the metal frame material 341 of the inner meeting frame 34. In this way, the fin member 444 seals the gap between the inner meeting frame 34 and the outer meeting frame 44 at the outermost side of the outer sash 4.

[0022] The sliding window 1 of this embodiment has the following advantages due to the fin member 444 configured as described above. That is, because the fin member 444 is attached to the outer joining frame 44, unlike when it is attached to the inner joining frame 34, it does not need to be attached in a way that avoids interference with the anti-vibration components (not shown) that are attached to the upper and lower ends of the inner joining frame 34. The fin member 444 does not interfere with the crescent receiver 48, so there is no need to provide a notch in the fin member 444 to avoid the crescent receiver 48. Therefore, with this sliding window 1, the fin member 444 can easily seal the gap between the inner joining frame 34 and the outer joining frame 44.

[0023] 5, the fin member 444 of this embodiment is provided throughout the entire length of the outer junction frame 44 in the extension direction, from the upper end 44a to the lower end 44b of the outer junction frame 44. Therefore, with this sliding window 1, the fin member 444 can reliably seal the space between the inner junction frame 34 and the outer junction frame 44 over their entire length without being affected by the anti-vibration parts and crescent holder 48.

[0024] In the sliding window 1 of this embodiment, a labyrinth made up of the inner extension piece 3411 and the outer extension piece 4411 is arranged on the outside of the fin member 444, and furthermore, a gasket 443 is provided on the outer side of that, the outer joining frame 44. These labyrinths and gasket 443 greatly reduce wind that enters the fin member 444 from the outside of the room. Therefore, combined with the fact that the fin member 444 is provided through the outer joining frame 44, the airtightness between the inner joining frame 34 and the outer joining frame 44 is greatly improved.

[0025] The outer joining frame 44 has a metal frame material 441 and a resin cover material 442 that is provided on the interior side of the metal frame material 441 over the entire length in the extension direction of the metal frame material 441. The fin member 444 is provided on the resin cover material 442. Therefore, by attaching the resin cover material 442 having the fin member 444 to the metal frame material 441, the fin member 444 can be easily provided on the outer joining frame 44.
