Summary of the Invention
Problems to be Solved by the Invention
[0004] The lower frame structure in a building fitting includes a rail structure in which the rail projects upward and a flat rail structure in which the upward projection amount of the rail is reduced from the viewpoint of barrier-free. However, since the structures of the rail structure and the flat rail structure are different, they need to be manufactured with separate facilities. Therefore, there is a problem that the manufacturing cost of the lower frame increases.
[0005] An object of the present disclosure is to provide a building fitting with a shielding member having a lower frame structure capable of reducing the manufacturing cost.
Means for Solving the Problems
[0006] The present disclosure relates to a fitting including a shielding member that can be opened and closed in the vertical direction on the outdoor side of an outer shutter and an inner shutter that are slidably housed in a frame body. The lower frame constituting the frame body includes a lower frame main body on which the outer shutter and the inner shutter are placed, a shielding member lower frame portion having a shielding member receiving portion for receiving the lower end portion of the shielding member, and a lower frame attachment that is detachable from the lower frame main body and the shielding member lower frame portion. The lower frame main body includes an outdoor side rail for guiding the movement of the outer shutter and an indoor side rail for guiding the movement of the inner shutter. The lower frame attachment includes a rail height filling member disposed on the lower frame main body for filling the heights of the outdoor side rail and the indoor side rail, and a shielding member receiving portion height filling member disposed on the shielding member lower frame portion for filling the height of the outdoor side rail in the shielding member receiving portion.

The lower frame 22 is also used as the shutter lower frame portion 26 of the shutter device 6 described later, and the details thereof will be described later.
[0016] The vertical frames 23 and 24 are extrusion-molded members formed of a metal material such as aluminum. The vertical frame 23 is a vertical frame disposed on the door tip side of the outer shutter 3. The vertical frame 24 is a vertical frame disposed on the door tip side of the inner shutter 4.
[0017] The vertical frame 23 integrally has a hollow structure portion 231 that extends longitudinally in the indoor-outdoor direction, a guide rail mounting portion 232 that protrudes inwardly at the end portion of the outdoor side Y1 of the hollow structure portion 231, and an indoor side extension portion 233 that extends from the end portion of the indoor side Y2 of the hollow structure portion 231 to the indoor side Y2. A resin cover material 234 is attached to the inner surface of the indoor side extension portion 233. The resin cover material 234 is provided across the entire length of the vertical frame 23 in the extending direction. The resin cover material 234 is disposed on the indoor side Y2 of the inner surface of the vertical frame 23, closer to the indoor side than the closed outer shutter 3. An angle portion 235 that protrudes further toward the indoor side Y2 than the resin cover material 234 is provided on the indoor side extension portion 233.
[0018] The vertical frame 24 integrally includes a hollow structure portion 241 extending longitudinally in the indoor-outdoor direction, a guide rail mounting portion 242 provided to protrude inwardly at the end of the outdoor side Y1 of the hollow structure portion 241, and an indoor side extension portion 243 extending from the end of the indoor side Y2 of the hollow structure portion 241 to the indoor side Y2. The indoor side extension portion 243 further has an angle portion 244 protruding toward the indoor side Y2.
[0019] As shown in FIGS. 2 and 3, the outer shutter 3 is configured by accommodating a face material 35 composed of three glasses inside a frame body 30 formed by rectangularly framing an upper frame 31, a lower frame 32, a vertical frame 33 disposed on the door tip side, and an outer call-together frame 34 which is a vertical frame disposed on the door butt side. The outer shutter 3 is slidably engaged in the left-right direction with the outdoor side rails 21a and 221a of the upper frame 21 and the lower frame 22. A door wheel 36 is provided on the lower frame 32 of the outer shutter 3 to roll on the outdoor side rail 221a of the lower frame 22.
[0020] As shown in FIGS. 2 and 3, the inner shutter 4 is configured by accommodating a face material 45 composed of three glasses inside a frame body 40 formed by rectangularly framing an upper frame 41, a lower frame 42, a vertical frame 43 disposed on the door tip side, and an inner call-together frame 44 which is a vertical frame disposed on the door butt side. The inner shutter 4 is movably engaged in the left-right direction with the indoor side rails 21b and 221b of the upper frame 21 and the lower frame 22. A door wheel 46 is provided on the lower frame 42 of the inner shutter 4 to roll on the indoor side rail 221b of the lower frame 22. The number of glasses used for the face materials 35 and 45 accommodated in the outer shutter 3 and the inner shutter 4 is not limited to three. The face materials 35 and 45 may be composed of, for example, two glasses.
[0021] As shown in FIGS. 2 and 3, the upper frame 31, lower frame 32, vertical frames 33, and outer call-together frame 34 of the outer shutter 3 each have a composite structure in which resin frame members 312, 322, 332, and 342 are attached to the indoor side Y2 of the metal frame members 311, 321, 331, and 341. The upper frame 41, lower frame 42, vertical frames 43, and inner call-together frame 44 of the inner shutter 4 each have a composite structure in which resin frame members 412, 422, 432, and 442 are attached to the indoor side Y2 of the metal frame members 411, 421, 431, and 441. As a result, the outer shutter 3 and the inner shutter 4 are excellent in heat insulation and dew prevention. On the outdoor side Y1 surfaces of the metal frame members 321 and 421 in the lower frames 32 and 42 of the outer shutter 3 and the inner shutter 4, extension plates 321b and 421b that extend further downward from the lower ends of the outdoor side lower end vertical walls 321a and 421a are integrally provided. The extension plates 321b and 421b protrude below the door wheels 36 and 46.
[0022] As shown in FIGS. 2 and 3, the screen door 5 is configured by stretching a mesh member 55 inside a frame body 50 formed by rectangularly framing an upper frame 51, a lower frame 52, a vertical frame 53 arranged on the door tip side, and a vertical frame 54 arranged on the door butt side. The screen door 5 is engaged with the screen door rails 21c and 221c of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction. A door wheel 56 that rolls on the screen door rail 872 of the lower frame 22 is provided on the lower frame 52 of the screen door 5.
[0023] As shown in FIGS. 1 to 3, a shutter device 6 is attached to the outdoor side Y1 of the outer shutter 3. The shutter device 6 includes a shutter device main body 61 and a pair of left and right guide rails 62 and 62. The shutter device main body 61 is attached to the outdoor surface 102 side of the building body 100 above the upper frame 21.
[0024] The shutter device main body 61 includes a horizontally long box-shaped shutter cover 611 and a shutter curtain 612 as a shielding member. The shutter curtain 612 is configured by connecting a plurality of horizontally long and narrow slats 6121 in the vertical direction. The shutter curtain 612 is accommodated in a wound state inside the shutter cover 611. A sill 613 is attached to the lower end of the shutter curtain 612. The lower end of the shutter curtain 612 is the tip in the payout direction of the shutter curtain 612. As shown in FIGS. 2 and 5, the sill 613 is formed wider in the indoor-outdoor direction than the shutter curtain 612. A contact member 6131 that contacts a shutter receiving surface 810 to be described later is provided over the entire length of the sill 613 in the extending direction. The contact member 6131 is an elastic member such as rubber, a brush member, or the like.
[0025] The guide rails 62, 62 extend from both left and right ends of the shutter device main body 61 along the vertical frames 23, 24 to the lower frame 22. The guide rails 62, 62 are arranged on the outdoor side Y1 of the vertical frames 23, 24. The guide rails 62, 62 are extrusion-molded members formed of a metal material such as aluminum, and are fixed to the guide rail attachment portions 232, 242 of the left and right vertical frames 23, 24 with screws 62a. As shown in FIG. 3, the guide rails 62, 62 have guide grooves 621, 621 on their opposing side surfaces for accommodating both left and right side portions of the shutter curtain 612, respectively. Contact members 6211 that contact the shutter curtain 612 from the outdoor side Y1 and the indoor side Y2, respectively, are attached over the entire length of the guide rails 62, 62 to the guide grooves 621, 621. The contact members 6211, 6211 are, for example, brush members, and prevent foreign matter such as dust from entering the guide rails 62, 62 through the gaps between the shutter curtain 612 and the guide grooves 621, 621.
[0026] The shutter device 6 opens the inner space of the shutter cover 611, the guide rails 62, 62, and the lower frame 22 by winding the entire shutter curtain 612 and accommodating it in the shutter cover 611. The shutter device 6 moves the crossbar 613 downward toward the lower frame 22 and feeds out the shutter curtain 612 from the shutter cover 611 along the guide rails 62, 62, thereby shielding the inner space of the shutter cover 611, the guide rails 62, 62, and the lower frame 22 as shown in FIG. 1. The shutter device 6 may be configured to manually wind and feed out the shutter curtain 612, or may be configured to automatically perform the winding and feeding out by a motor drive (not shown).
[0027] As shown in FIG. 8, a locking mechanism 6122 is provided on some slats 6121 of the shutter curtain 612. The locking mechanism 6122 has a locking bar 6122a extending in the left-right direction. The locking bar 6122a is provided so as to be movable in the left-right direction. When the locking bar 6122a is arranged at a locking position where it protrudes toward the guide rail 62 in a state where the shutter curtain 612 is arranged at the shielding position, the tip of the locking bar 6122a engages with an engagement hole (not shown) formed in the guide rail 62, locking the shutter curtain 612 at the shielding position. Since there is no need to form a mechanism for locking the shutter curtain 612 at the shielding position between the lower frame 22, the structure of the lower frame 22 can be simplified. A pair of left and right locking bars 6122a are provided on the shutter curtain 612 to engage with the left and right guide rails 62, 62 respectively.
[0028] Next, the lower frame structure of the fitting 1 will be described in detail with reference to FIGS. 4 to 7. The lower frame structure of the fitting 1 in the present embodiment is configured such that the upper surface of the lower frame 22 becomes flat by attaching the lower frame attachment AT, and is a flat rail structure 10 (see FIGS. 2, 4, and 5), and can be used for both a rail structure 10A (see FIG. 9) configured such that the rail protrudes upward by removing the lower frame attachment AT. Therefore, it is not necessary to manufacture the flat rail structure 10 and the rail structure 10A with separate facilities, and the manufacturing cost of the lower frame 22 can be reduced.
[0029] First, the lower frame 22 having the flat rail structure 10 configured by attaching the lower frame attachment AT will be described. The lower frame 22 includes a lower frame main body 25, a shutter lower frame portion 26, and a lower frame attachment AT. The lower frame attachment AT is disposed on the inner surface of the lower frame 22 and is detachable from the lower frame main body 25 and the shutter lower frame portion 26. The inner surface of the lower frame 22 is also the upper surface of the lower frame 22.
[0030] As shown in FIG. 4, the lower frame main body 25 is divided into an outdoor side metal frame body 251 and an indoor side metal frame body 252. The outdoor side metal frame body 251 and the indoor side metal frame body 252 are extruded members formed of a metal material such as aluminum. The outdoor side metal frame body 251 and the indoor side metal frame body 252 are integrally connected by a heat-insulating connecting member 253 made of a resin material or the like.
[0031] The outdoor side metal frame body 251 is formed in a substantially rectangular cross-section by an upper wall portion 251a, an outdoor wall portion 251b, a lower wall portion 251c, and an indoor wall portion 251d, and has a hollow portion 251e inside. The upper wall portion 251a has an outdoor side rail 221a that guides the sliding movement of the lower end portion of the outer shutter 3, and a screen door rail 221c that guides the sliding movement of the lower end portion of the screen door 5 on the outdoor side of the outdoor side rail 221a.
[0032] The indoor-side metal frame 252 is formed into a rectangular cross-section by an upper wall portion 252a, an outdoor wall portion 252b, a lower wall portion 252c, and an indoor wall portion 252d, and has a hollow portion 252e inside. The upper wall portion 252a has an indoor-side rail 221b that guides the sliding movement of the lower end portion of the inner blind 4. At the end of the indoor side Y2 of the upper wall portion 252a, a standing wall portion 252f that protrudes upward is formed. A groove portion 252g is provided at the upper end portion of the standing wall portion 252f. A resin angle portion 254 that extends toward the indoor side Y2 is attached to the groove portion 252g.
[0033] The shutter lower frame portion 26 is a lower frame portion of the shielding member. The shutter lower frame portion 26 is disposed at the end of the outdoor side Y1 of the lower frame body 25. The shutter lower frame portion 26 is integrally provided on the outdoor wall portion 251b of the lower frame body 25. That is, the lower frame body 25 and the shutter lower frame portion 26 are configured as an integral frame.
[0034] The shutter lower frame portion 26 has an extending wall portion 261 that extends from the middle portion in the vertical direction of the outdoor wall portion 251b of the lower frame body 25 toward the outdoor side Y1, and a standing wall portion 262 that is disposed at the end of the outdoor side Y1 of the extending wall portion 261 and extends in the vertical direction. The height position of the upper end of the standing wall portion 262 substantially coincides with the height position of the upper wall portion 251a of the lower frame body 25. Thereby, a shutter receiving portion 263 formed in a concave shape by the shutter lower frame portion 26 and the outdoor wall portion 251b is disposed on the outdoor side Y1 of the lower frame body 25. As shown in FIG. 9, the shutter receiving portion 263 is a portion that receives the sill 613A of the shutter curtain 612 that has moved downward when the lower frame 22 is used as the rail structure 10A.
[0035] The lower frame attachment AT is attached to the lower frame body 25 and the shutter lower frame portion 26, thereby constituting the lower frame 22 of the flat rail structure 10 together with the lower frame body 25 and the shutter lower frame portion 26. As shown in FIGS. 4 and 5, the lower frame attachment AT is composed of a rail height filling member 7 and a shutter receiving portion height filling member 8. The rail height filling member 7 is attached to the inner surface of the lower frame body 25 to fill the heights of the outdoor side rail 221a and the indoor side rail 221b that protrude upward from the lower frame body 25 and to flatten the inner surface of the lower frame body 25. The shutter receiving portion height filling member 8 is attached across the lower frame body 25 and the shutter lower frame portion 26 to fill the height between the shutter lower frame portion 26 and the outdoor side rail 221a and to flatten the inner surface extending from the lower frame body 25 to the shutter lower frame portion 26.
[0036] The rail height filling member 7 includes a between-rail member 71, an indoor side member 72, an outdoor side rail cap member 73, and an indoor side rail cap member 74. The rail height filling member 7 is provided over the entire length in the extending direction of the lower frame 22.
[0037] The between-rail member 71 is disposed between the outdoor side rail 221a and the indoor side rail 221b on the inner surface of the lower frame body 25 and is attached to the lower frame body 25. The between-rail member 71 has a height equivalent to the protruding heights of the outdoor side rail 221a and the indoor side rail 221b. The upper surface of the between-rail member 71 is formed flat. Thereby, the between-rail member 71 fills the height between the outdoor side rail 221a and the indoor side rail 221b and forms a flat surface therebetween.
[0038] The intermediate rail member 71 is composed of a lower member 711 having a substantially E-shaped cross-section arranged on the lower side and open upward, and an upper member 712 having a substantially E-shaped cross-section arranged on the upper side of the lower member 711 and open downward, which are combined. The lower member 711 and the upper member 712 are extrusion-molded members formed of a metal material such as aluminum. The lower member 711 is fixed to the upper wall portion 251a on the indoor side Y2 of the outdoor-side rail 221a by screws 71a. The upper member 712 is fitted into the lower member 711 fixed to the upper wall portion 251a from above. Since the intermediate rail member 71 can be attached to the lower frame body 25 by fitting the upper member 712 after fixing the lower member 711 to the upper wall portion 251a, the intermediate rail member 71 has excellent attachability to the lower frame body 25.
[0039] The indoor-side member 72 is arranged on the indoor side Y2 of the indoor-side rail 221b on the upper surface of the lower frame body 25 and is attached to the lower frame body 25. The indoor-side member 72 is an extrusion-molded member formed of a metal material such as aluminum. The indoor-side member 72 is formed in a frame shape with an open bottom. The upper surface of the indoor-side member 72 is flat. Thus, the indoor-side member 72 fills the height between the indoor-side rail 221b and the angle portion 254 and forms a flat surface therebetween.
[0040] The outdoor-side rail cap member 73 is attached to the upper end portion of the outdoor-side rail 221a. The outdoor-side rail cap member 73 has a running surface 731 formed at the upper portion on which the door wheel 36 of the outer shutter 3 runs, an engaging portion 732 formed at the lower portion of the running surface 731, and an airtight material 733 made of an elastic material such as rubber provided on the side portion of the outdoor side Y1. The running surface 731 and the engaging portion 732 are integrally formed of a metal material such as aluminum. The running surface 731 is formed in a curved shape convex upward. The engaging portion 732 is engaged and attached to the upper end portion of the outdoor-side rail 221a. A gap into which the extended plate 321b of the lower frame 32 of the outer shutter 3 can be inserted is formed between the airtight material 733 and a shutter receiving portion height filling member 8 described later. When the extended plate 321b is inserted into this gap, the airtight material 733 is pressed by the side surface on the indoor side Y2 of the extended plate 321b.
[0041] The indoor side rail cap member 74 is attached to the upper end portion 221b1 of the indoor side rail 221b. The indoor side rail cap member 74 has a running surface 741 formed at the upper part on which the door wheel 46 of the inner blind 4 runs, an engaging portion 742 formed at the lower part of the running surface 741, and an airtight material 743 made of an elastic material such as rubber provided on the side portion on the outdoor side Y1. The running surface 741 and the engaging portion 742 are integrally formed of a metal material such as aluminum. The running surface 741 is formed in a curved surface shape convex upward. The engaging portion 742 is engaged and attached to the upper end portion of the indoor side rail 221b. A gap into which the extension plate 421b of the lower frame 42 of the inner blind 4 can be inserted is formed between the airtight material 743 and the rail intermediate member 71. When the extension plate 421b is inserted into this gap, the airtight material 743 is pressed by the side surface on the indoor side Y2 of the extension plate 421b.
[0042] The shutter receiving portion height filling member 8 is a shielding member receiving portion height filling member. The shutter receiving portion height filling member 8 is disposed on the inner surface of the lower frame body 25 extending from the lower frame portion 26 of the shutter to the outdoor side Y1 of the outdoor side rail 221a. The shutter receiving portion height filling member 8 is an extruded shape member formed of a metal material such as aluminum. As shown in FIGS. 4 to 6, the shutter receiving portion height filling member 8 has an upper wall portion 81, an outdoor wall portion 82, an indoor wall portion 83, and a lower wall portion 84. The upper wall portion 81, the outdoor wall portion 82, the indoor wall portion 83, and the lower wall portion 84 are formed in a rectangular cross section, and a hollow portion 85 is formed inside.
[0043] The upper wall portion 81 extends to the outdoor side Y1 more than the outdoor wall portion 82. The end portion on the outdoor side Y1 of the upper wall portion 81 integrally has a hanging piece portion 811 bent downward in an L shape. The upper surface of the upper wall portion 81 corresponding to the hollow portion 85 constitutes a shutter receiving surface 810 facing the crossbar 613 of the shutter curtain 612 as shown in FIGS. 2 and 5. The lower end portions of the left and right guide rails 62, 62 are disposed at both left and right end portions of the shutter receiving surface 810.
[0044] As shown in FIG. 5, the height position of the shutter receiving surface 810 is substantially equal to the height positions of the upper ends of the outdoor side rail 221a and the indoor side rail 221b in a state where the shutter receiving portion height filling member 8 is attached to the lower frame 22. The shutter receiving surface 810 is formed in a flat shape without protruding portions such as rails and fins from the portion facing the lintel 613 to the outermost outdoor side Y1 hanging piece portion 811. The shutter receiving surface 810 receives the lintel 613 of the shutter curtain 612 in the closed state with a flat surface over the entire length from the outdoor side Y1 end portion 613a to the indoor side Y2 end portion 613b of the lintel 613. Thereby, for example, when the outdoor side Y1 of the lower frame 22 is flush with a wood deck (not shown), when the shutter curtain 612 is opened, the movement in the indoor-outdoor direction by a wheelchair or the like can be smoothly performed, and the safety is improved. Since the shutter receiving surface 810 is in a flat shape, the design property is also improved.
[0045] As shown in FIG. 6, a plurality of serrations 812 extending along the extending direction of the shutter receiving portion height filling member 8 are formed on the shutter receiving surface 810. The serrations 812 have a shape that protrudes upward to such an extent that they do not become an obstacle during the movement of a wheelchair or the like, and are formed at regular intervals in the indoor-outdoor direction. Thereby, the shutter receiving surface 810 has an anti-slip effect, and the water that has entered onto the shutter receiving surface 810 is suppressed from flowing from the outdoor side Y1 toward the indoor side Y2.
[0046] The outdoor wall portion 82 extends downward from the lower surface of the upper wall portion 81 on the indoor side Y2 of the hanging piece portion 811. The outdoor wall portion 82 has an outdoor side attachment portion 821 that extends further downward than the lower wall portion 84. The outdoor side attachment portion 821 constitutes an attachment portion on the outdoor side Y1 of the shutter receiving portion height filling member 8 to the shutter lower frame portion 26. As shown in FIG. 5, the outdoor side attachment portion 821 abuts against the standing wall portion 262 of the shutter lower frame portion 26 from the outdoor side Y1 and is fixed by a screw 8a.
[0047] The indoor wall portion 83 extends downward from the lower surface of the upper wall portion 81 corresponding to the indoor-side end portion 810a of the shutter receiving surface 810. The indoor wall portion 83 has a protruding portion 831 that protrudes downward more than the lower wall portion 84. As shown in FIG. 5, when the shutter receiving portion height filling member 8 is attached to the lower frame 22, the protruding portion 831 is a portion that abuts against the upper surface of the upper wall portion 251a on the outdoor side Y1 of the sash rail 221c in the lower frame body 25. As shown in FIGS. 4 and 5, tapping holes 251f, which are protrusions, are formed over the entire length in the extending direction of the lower frame body 25 on the lower surface side of the upper wall portion 251a against which the protruding portion 831 abuts. Thereby, since the load-bearing capacity of the upper wall portion 251a against which the protruding portion 831 abuts is improved, the indoor side Y2 of the shutter receiving portion height filling member 8 is stably supported by the lower frame body 25.
[0048] The lower wall portion 84 is formed across the lower end portion of the outdoor wall portion 82 and the lower end portion of the indoor wall portion 83. The lower wall portion 84 has a stepped portion 841 with a downwardly bent shape at the connection portion with the outdoor wall portion 82. The outdoor attachment portion 821 extends downward from the connection portion between the outdoor wall portion 82 and the stepped portion 841. The stepped portion 841 has an outdoor support wall portion 841a. The outdoor support wall portion 841a extends from the connection portion of the stepped portion 841 with the outdoor wall portion 82 toward the indoor side Y2. When the shutter receiving portion height filling member 8 is attached across the lower frame body 25 and the shutter lower frame portion 26, the outdoor support wall portion 841a is placed on the vertical wall portion 262 of the shutter lower frame portion 26 shown in FIG. 4 from above. Therefore, the outdoor side Y1 of the shutter receiving portion height filling member 8 is stably supported by the vertical wall portion 262.
[0049] The upper wall portion 81 extends further toward the indoor side Y2 than the indoor wall portion 83. A water return portion 86 is formed on the upper wall portion 81. The water return portion 86 is disposed adjacent to the indoor side Y2 of the shutter receiving surface 810 on the upper wall portion 81 and is formed over the entire length in the extending direction of the shutter receiving portion height filling member 8.
[0050] The water return portion 86 is formed in a shape that gently protrudes above the shutter receiving surface 810. Specifically, as shown in FIG. 7, the water return portion 86 includes an outdoor rising surface 861 that rises obliquely upward from the indoor-side end 810a of the shutter receiving surface 810 toward the indoor side Y2, an upper end surface 862 that extends flat in the indoor-outdoor direction, and an indoor side surface 863 that bends downward from the end of the upper end surface 862 on the indoor side Y2. The connecting portions of the outdoor rising surface 861, the upper end surface 862, and the indoor side surface 863 are rounded in an R shape.
[0051] The protruding height of the water return portion 86, that is, the height position of the upper end surface 862, is slightly higher than the protruding heights of the outdoor rail 221a and the indoor rail 221b in a state where the shutter receiving portion height filling member 8 is attached to the lower frame 22, and is substantially equal to the height positions of the running surfaces 731 and 741 of the outdoor rail cap member 73 and the indoor rail cap member 74.
[0052] By forming the water return portion 86 on the shutter receiving portion height filling member 8, together with the plurality of serrations 812 on the shutter receiving surface 810, the intrusion of water on the shutter receiving surface 810 into the indoor side Y2 is further suppressed. Therefore, water does not accumulate between the shutter receiving portion height filling member 8 and the outer shutter 3. Since the upper end surface 862 of the water return portion 86 is a flat surface, the user does not feel pain even when stepping on it barefoot. The indoor wall portion 83 extends downward from the lower surface of the upper end surface 862 of the water return portion 86 and is placed on the lower frame body 25. Thus, the water return portion 86 is supported by the indoor wall portion 83 against the load from above, so it has high load resistance and there is no possibility of deformation or the like due to repeated stepping.
[0053] An indoor extension portion 87 is integrally formed on the indoor side Y2 of the water return portion 86. The indoor extension portion 87 extends from the lower end of the indoor side surface 863 of the water return portion 86 toward the indoor side Y2. The height position of the indoor extension portion 87 is arranged slightly below the height position of the shutter receiving surface 810 on the upper wall portion 81.
[0054] At the end of the indoor-side extension part 87 on the indoor side Y2, a fin 871 protruding upward is formed. When the shutter receiving part height filling member 8 is attached to the lower frame body 25 and the shutter lower frame part 26, the fin 871 is arranged to face the airtight material 733 of the outdoor-side rail cap member 73 from the outdoor side Y1. Thus, when the exterior shutter 3 moves to the outdoor side Y1 due to wind pressure or the like, the fin 871 abuts against the extension plate 321b of the lower frame 32 of the exterior shutter 3 from the outdoor side Y1, preventing the lower end part of the exterior shutter 3 from moving excessively to the outdoor side Y1. As shown in FIG. 7, a convex part 871a protruding toward the indoor side Y2 is formed on the side surface of the fin 871 on the indoor side Y2.
[0055] On the indoor-side extension part 87, a screen door rail 872 protruding upward is formed at a position on the outdoor side Y1 relative to the fin 871 and on the indoor side Y2 relative to the indoor-side surface 863 of the water return part 86. As shown in FIG. 5, when the shutter receiving part height filling member 8 is attached to the lower frame 22, the screen door rail 872 is provided above the screen door rail 221c formed on the lower frame body 25 and at the same position in the indoor-outdoor direction as the position of the screen door rail 221c. The height position of the upper end part of the screen door rail 872 is higher than the height position of the upper end part of the fin 871 and is equivalent to the height position of the upper end surface 862 of the water return part 86.
[0056] In the shutter receiving part height filling member 8, the indoor-side extension part 87 having the screen door rail 872 is formed of a single member with the part where the shutter receiving surface 810 is provided. Since it is not necessary to form the part of the screen door rail 872 separately, no gap between members is formed between the shutter receiving surface 810 and the screen door rail 872. Therefore, the safety and design of the lower frame 22 are improved, and the manufacturing cost is also reduced.
[0057] On the indoor side extension part 87, as shown in FIGS. 6 and 7, groove parts 87a and 87b are formed by the indoor side surface 863 of the water return part 86, the fins 871, and the screen door rail 872. The groove part 87a is formed between the fin 871 and the screen door rail 872. The groove part 87b is formed between the fin 871 and the water return part 86. These groove parts 87a and 87b respectively have groove widths W1 and W2 in the indoor-outdoor direction and groove depths D1 and D2. The groove parts 87a and 87b are formed so as to satisfy at least one of a groove width of 5 mm or more and 13 mm or less and a groove depth of 5 mm or less. Thereby, the safety is improved by preventing a child's finger from being pinched.
[0058] As shown in FIG. 6, since the groove depth D1 of the groove part 87a is formed to be less than 5 mm, a child's finger cannot enter deep into the groove part 87a, and the safety is ensured. Regarding the part where the groove depth D2 is 5 mm or more in the groove width W2 of the groove part 87b, since the groove width is formed to be less than 5 mm, a child's finger cannot enter, and the safety is ensured. Furthermore, the cleanability of the dust accumulated in the groove parts 87a and 87b is also improved. From the viewpoints of the same safety and cleanability, in the case of a groove part with a groove depth of 5 mm or more, the groove width along the indoor-outdoor direction is formed in a wide shape exceeding 13 mm.
[0059] On the lower surface side of the indoor side extension part 87, a hanging wall part 88 is integrally formed. The hanging wall part 88 extends downward from the lower surface of the indoor side extension part 87 corresponding to a position slightly outside the outdoor side Y1 from the screen door rail 872.
[0060] At the lower end of the hanging wall portion 88, an indoor mounting portion 89 extending toward the indoor side Y2 is integrally formed. The indoor mounting portion 89 is a mounting portion on the indoor side Y2 for attaching the shutter receiving portion height filling member 8 to the lower frame body 25. The indoor mounting portion 89 protrudes more toward the indoor side Y2 than the indoor extending portion 87. As shown in FIGS. 4 and 5, the indoor mounting portion 89 is disposed on the inner surface of the upper wall portion 251a between the outdoor rail 221a and the screen door rail 221c of the lower frame body 25. The indoor mounting portion 89 extends toward the outdoor rail 221a side. The indoor mounting portion 89 abuts against the base of the outdoor rail 221a from the outdoor side Y1 and is fixed to the lower frame body 25 by screws 8b.
[0061] In the upper wall portion 251a, a tapping hole 251g, which is a protrusion, is formed on the lower surface side of the portion through which the screw 8b penetrates. The tapping hole 251g is formed over the entire length of the lower frame body 25 in the extending direction. The screw 8b penetrates the upper wall portion 251a and is screwed into the tapping hole 251g. Thereby, the indoor mounting portion 89 is firmly fixed to the lower frame body 25.
[0062] The fixing portion by the screw 8b is disposed at the end of the indoor side Y2 in the indoor mounting portion 89. As shown in FIG. 5, above the indoor mounting portion 89, an outdoor rail cap member 73 attached to the outdoor rail 221a is disposed. Since the outdoor rail cap member 73 is disposed so as to project toward the outdoor side Y1 of the outdoor rail 221a, the screw 8b is concealed by the outdoor rail cap member 73 and is difficult to be visually observed. Therefore, even if the shutter receiving portion height filling member 8 is screwed from the inner surface, the design property is not impaired.
[0063] The indoor mounting portion 89 has a stepped portion 891 at the connection portion with the lower end portion of the hanging wall portion 88. As shown in FIG. 6, the stepped portion 891 is formed in a crank shape in which the indoor mounting portion 89 extending from the hanging wall portion 88 toward the indoor side Y2 bends downward so as to follow the inner surface of the upper wall portion 251a while avoiding the screen door rail 221c of the lower frame body 25. The stepped portion 891 has an indoor support wall portion 891a at the connection portion with the lower end portion of the hanging wall portion 88. The indoor support wall portion 891a extends from the connection portion of the stepped portion 891 with the hanging wall portion 88 toward the indoor side Y2. The indoor support wall portion 891a is disposed directly below the screen door rail 872. When the shutter receiving portion height filling member 8 is attached to the lower frame 22, the indoor support wall portion 891a abuts against the screen door rail 221c of the lower frame body 25 from above. Thereby, the shutter receiving portion height filling member 8 is stably supported by the screen door rail 221c at the end portion of the indoor side Y2.
[0064] By attaching the lower frame attachment AT configured as described above to the lower frame body 25 and the shutter lower frame portion 26, as shown in FIG. 5, the upper surface of the lower frame 22 is formed flat in the indoor-outdoor direction. Thereby, the lower frame 22 of the flat rail structure 10 is configured.
[0065] When configuring the lower frame 22 of the rail structure 10A shown in FIG. 9, from the lower frame 22 of the flat rail structure 10 including the lower frame attachment AT, all the lower frame attachments AT, that is, the rail height filling member 7 (the inter-rail member 71, the indoor member 72, the outdoor rail cap member 73, and the indoor rail cap member 74) and the shutter receiving portion height filling member 8 are removed, and the lower frame 22 of the rail structure 10A can be easily configured. On the inner surface of the lower frame body 25 from which the lower frame attachment AT has been removed, the outdoor rail 221a, the indoor rail 221b, and the screen door rail 221c project upward. The shutter lower frame portion 26 is continuous with the outdoor side Y1 of the lower frame body 25 and exposes the recessed shutter receiving portion 263 upward.
[0066] As shown in Fig. 9, resin cover materials 255 and 256 are attached to the upper surface of the lower frame body 25 of the lower frame 22 of the rail structure 10A. Thereby, the lower frame 22 of the rail structure 10A is excellent in heat insulation and dew prevention properties. The resin cover material 255 is disposed between the outdoor rail 221a and the indoor rail 221b on the inner surface of the outdoor side metal frame body 251. The resin cover material 256 is disposed on the inner surface of the indoor side metal frame body 252 on the indoor side Y2 rather than the indoor rail 221b. The resin cover material 255 is provided over the region exposed to the indoor side Y2 when the outer shutter 3A and the inner shutter 4A are fully closed between the outdoor rail 221a and the indoor rail 221b. The resin cover material 256 is provided over the entire length in the extending direction of the lower frame 22.
[0067] The lower frames 32A and 42A of the outer shutter 3A and the inner shutter 4A housed in the lower frame 22 of the rail structure 10A are different from the lower frames 32 and 42 of the outer shutter 3 and the inner shutter 4 housed in the lower frame 22 of the flat rail structure 10 in that the indoor-outdoor width of the door wheels 36A and 46A is small and that the extending plates 321b and 421b provided on the lower frames 32 and 42 of the outer shutter 3 and the inner shutter 4 are not provided.
[0068] As shown in Fig. 9, airtight materials 321c and 421c are attached to the inner surfaces of the outdoor side lower end vertical walls 321a and 421a on the outdoor side X1 of the metal frame materials 321 and 421 of the lower frames 32A and 42A. The airtight materials 321c and 421c are pressed in a bent state against the side surface on the outdoor side Y1 of the outdoor rail 221a and the side surface on the outdoor side Y1 of the indoor rail 221b, respectively.
[0069] The sill 613A of the shutter curtain 612 that has moved downward is housed in the recessed shutter receiving portion 263 of the shutter lower frame portion 26 in the lower frame 22. An L-shaped piece 6132 is provided on the side surface 613c on the outdoor side Y1 of the sill 613A of the shutter device 6 shown in Fig. 9 so as to sandwich the vertical wall portion 262 of the shutter lower frame portion 26 from above between the side surface 613c. Also in the lower frame 22 of the rail structure 10A, the sill 613 of the shutter curtain 612 shown in Figs. 2 and 5 can be used.
[0070] When changing the lower frame 22 of the rail structure 10A shown in FIG. 9 to the lower frame 22 of the flat rail structure 10, after removing the resin cover materials 255 and 256 from the lower frame body 25, as shown in FIG. 4, by attaching the lower frame attachment AT to the lower frame body 25 and the shutter lower frame portion 26, the lower frame 22 of the flat rail structure 10 can be easily configured.
[0071] According to the present embodiment, the following effects can be obtained.
[0072] (1) A fitting 1 including a shutter curtain 612 which is a shielding member that can be opened and closed in the vertical direction on the outdoor side Y1 of outer shutters 3, 3A and inner shutters 4, 4A that are slidably housed in a frame body 20. The lower frame 22 constituting the frame body 20 includes a lower frame body 25 on which the outer shutters 3, 3A and the inner shutters 4, 4A are placed, a shutter lower frame portion 26 which is a shielding member receiving portion that receives the lower end portion of the shutter curtain 612, and a lower frame attachment AT that is detachable from the lower frame body 25 and the shutter lower frame portion 26. The lower frame body 25 includes an outdoor side rail 221a that guides the movement of the outer shutters 3, 3A and an indoor side rail 221b that guides the movement of the inner shutters 4, 4A. The lower frame attachment AT includes a rail height filling member 7 that is disposed on the lower frame body 25 and fills the heights of the outdoor side rail 221a and the indoor side rail 221b, and a shutter receiving portion height filling member 8 that is disposed on the shutter lower frame portion 26 and fills the height of the outdoor side rail 221a at the shutter receiving portion 263, and is the fitting 1.
[0073] According to the above (1), by simply removing the lower frame attachment AT from the lower frame 22 constituting the flat rail structure 10, the lower frame 22 of the rail structure 10A can be easily configured. Since the lower frame structures other than the lower frame attachment AT can be shared between the flat rail structure 10 and the rail structure 10A, the manufacturing cost of the lower frame 22 can be reduced.
[0074] (2) In the fitting 1 described in (1) above, the shutter receiving portion height filling member 8 has a shutter receiving surface 810 which is a flat shielding member receiving surface extending from the portion facing the lower end portion of the shutter curtain 612 to the outermost outdoor side Y1.
[0075] According to (2) above, for example, when the outdoor side Y1 of the lower frame 22 is flush with a wooden deck or the like, the movement in the indoor-outdoor direction by a wheelchair or the like can be smoothly performed, and the safety is improved. Since the shutter receiving surface 810 has a flat shape, the design property is also improved.
[0076] (3) In the fitting 1 described in (2) above, the shutter receiving portion height filling member 8 has a screen door rail 872 which is disposed on the indoor side Y2 of the shutter receiving surface 810 and protrudes upward, and the shutter receiving surface 810 and the screen door rail 872 are formed of a single member.
[0077] According to (3) above, since no gap between members is formed between the shutter receiving surface 810 and the portion where the screen door rail 872 is provided, the safety when the user moves the lower frame 22 in the indoor-outdoor direction is improved and the design property is also improved. Since it is not necessary to separately manufacture the shutter receiving surface 810 and the portion where the screen door rail 872 is provided, the manufacturing cost is also reduced.
[0078] (4) In the fitting 1 described in (2) or (3) above, the shutter receiving portion height filling member 8 has a water return portion 86 on the indoor side Y2 of the shutter receiving surface 810.
[0079] According to (4) above, the intrusion of water onto the shutter receiving surface 810 toward the indoor side Y2 is suppressed, and water does not accumulate between the shutter receiving portion height filling member 8 and the outer shutter 3.
[0080] (5) In the fitting 1 described in any one of (1) to (4) above, the shutter receiving member height filling member 8 has a fin 871 which protrudes upward at the end of the indoor side Y2.
[0081] According to the above (5), when the exterior shutter 3 moves to the outdoor side Y1 due to wind pressure or the like, it abuts against the lower frame 32 of the exterior shutter 3 from the outdoor side Y1. Therefore, it is possible to prevent the lower end portion of the exterior shutter 3 from moving excessively to the outdoor side Y1.
[0082] (6) In the fitting 1 according to any one of the above (1) to (5), the groove portion 87a formed on the upper surface of the shutter receiving portion height filling member 8 has a groove width W in the indoor-outdoor direction of 5 mm or more and 13 mm or less, and a groove depth D of less than 5 mm.
[0083] According to the above (6), it is possible to prevent the fingers of infants from being pinched, improving safety, and also improving the cleanability of the dust accumulated in the groove portion 87a.
[0084] (7) In the fitting 1 according to any one of the above (1) to (6), the shutter receiving portion height filling member 8 has an indoor side attachment portion 89 with respect to the lower frame body 25, and the indoor side attachment portion 89 extends toward the outdoor side rail 221a side.
[0085] According to the above (7), since the fixing portion of the indoor side attachment portion 89 can be concealed by the rail height filling member 7 (outdoor side rail cap member 73), the design property is improved.
[0086] (8) In the fitting 1 according to any one of the above (1) to (7), the lower frame body 25 and the shutter lower frame portion 26 are configured as an integral frame.
[0087] According to the above (8), since the lower frame body 25 and the shutter lower frame portion 26 can be handled integrally, it is not necessary to perform positioning or the like between the lower frame body 25 and the shutter lower frame portion 26, and the workability of the lower frame 22 is improved as compared with the case where the lower frame body 25 and the shutter lower frame portion 26 are separate frames.
[0088] As described above, the preferred embodiment of the present disclosure has been described. However, the present disclosure is not limited to the above-described embodiment and can be appropriately changed.
