Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, the connection between the metal vertical frame and the metal horizontal frame is made by providing a tapping part such as a tapping hole on the metal horizontal frame side, and a tapping screw penetrates the metal vertical frame and is screwed into the tapping part of the metal horizontal frame to connect the metal vertical frame and the metal horizontal frame made of metal. Usually, a plurality of tapping parts, such as two places, are provided on the metal horizontal frame to ensure the joint strength and assembly accuracy between the metal vertical frame and the metal horizontal frame.

[0005] However, wooden frames, which are shaped by cutting or other processes, have less freedom in processing compared to resin frames or metal frames, which are shaped by injection molding or other processes, and cannot be formed into complex shapes. Therefore, metal frame covers to which such wooden frames are assembled may have only one tapping section to reduce interference with the wooden frame, as disclosed in the aforementioned Patent Document 1.

[0006] When joining a metal horizontal frame cover with only one tapping point to a metal vertical frame cover, the tapping screw penetrates the metal vertical frame cover and screws into the tapping point of the metal horizontal frame cover. However, because there is only one tapping point, the metal horizontal frame cover rotates together with the tapping screw, which reduces the ease of assembly and assembly accuracy of the wooden composite shoji screen.

[0007] Therefore, the present invention was made to solve these problems, and aims to provide a wooden composite shoji screen and wooden composite sash that, even when only one tapping part such as a tapping hole can be provided in the metal horizontal frame cover, does not rotate together with the tapping screw, thereby improving ease of assembly and assembly accuracy. [Means for solving the problem]

[0008] To solve the aforementioned problems, the wooden composite shoji screen according to the present invention is a wooden composite shoji screen in which the glass portion is surrounded on all four sides by left and right vertical frames having wooden vertical frames and metal vertical frame covers, and upper and lower horizontal frames having wooden horizontal frames and metal horizontal frame covers, wherein the metal vertical frame cover has a fixing piece through which a tapping screw passes toward the metal horizontal frame cover, and the metal horizontal frame cover has a tapping portion into which the tapping screw that has passed through the fixing piece is screwed, and either the metal vertical frame cover or the metal horizontal frame cover is provided with a rotation prevention portion that can abut against the other side when the metal horizontal frame cover rotates relative to the metal vertical frame cover with the tapping portion as the axis of rotation, thereby preventing the rotation of the metal horizontal frame cover relative to the metal vertical frame cover. Furthermore, in the wooden composite shoji screen according to the present invention, the metal vertical frame cover is provided with an outdoor exposed surface portion of the vertical frame cover having an outdoor exposed surface that is exposed to the outdoors, and a groove portion for attaching a trim material, which is provided on the glass portion side of the outdoor exposed surface portion of the vertical frame cover and into which a locking portion of a trim material that holds down the glass portion is locked. On the other hand, the metal horizontal frame cover is provided with an outdoor exposed surface portion of the horizontal frame cover having an outdoor exposed surface that is exposed to the outdoors, and a tapping portion that extends from the outdoor exposed surface portion of the horizontal frame cover toward the indoor side and has the wooden horizontal frame fixed therein. A tapping screw passes through an upper projection for mounting a wooden horizontal frame, and a part of the anti-rotation part is inserted into the groove for mounting the trim material on the indoor side surface near the metal vertical frame cover on the outdoor exposed surface of the horizontal frame cover. The anti-rotation part is provided so as to contact the outdoor outer piece or indoor inner piece for pressing down the trim material that constitutes the groove for mounting the trim material of the metal vertical frame cover when the metal horizontal frame cover rotates relative to the metal vertical frame cover with the tapping part as the axis of rotation. Furthermore, in the wooden composite shoji screen according to the present invention, the anti-rotation part is a separate anti-rotation member from the metal horizontal frame cover, and is provided on the indoor side surface near the metal vertical frame cover on the outdoor exposed surface of the horizontal frame cover. Furthermore, in the wooden composite shoji screen according to the present invention, the metal horizontal frame cover is a metal horizontal frame cover of the lower frame, and the end of the upper projection for attaching the metal horizontal frame is provided with a drainage opening to allow water to drain downward, and the anti-rotation part is provided on the indoor side surface near the metal vertical frame cover on the outdoor exposed surface of the horizontal frame cover so as to leave a gap in the vertical direction without completely blocking the drainage opening. Furthermore, the wooden composite shoji screen according to the present invention is characterized in that one of the above-mentioned wooden composite shoji screens is provided in the window space formed by left and right vertical frames and upper and lower horizontal frames having wooden and metal frames. [Effects of the Invention]

[0009] In the wooden composite shoji screen according to the present invention, the metal vertical frame cover has screw holes, while the metal horizontal frame cover has a tapping portion into which tapping screws that penetrate the screw holes of the metal vertical frame cover are screwed in to fix the metal vertical frame cover. Either the metal vertical frame cover or the metal horizontal frame cover is provided with a rotation prevention portion that, when the metal horizontal frame cover rotates relative to the metal vertical frame cover due to the rotation of the tapping screws screwed into the tapping portion, comes into contact with the other side to prevent the metal horizontal frame cover from rotating relative to the metal vertical frame cover. Therefore, even if only one tapping section can be provided on the metal horizontal frame cover, when the tapping screw is screwed into the tapping section and rotates, the anti-rotation section provided on either the metal vertical frame cover or the metal horizontal frame cover comes into contact with the other side, preventing the metal horizontal frame cover from rotating relative to the metal vertical frame cover. As a result, the metal horizontal frame cover does not rotate together with the tapping screw, improving the ease of assembly and assembly accuracy between the metal horizontal frame cover and the metal vertical frame cover.

[0049] As shown in Figures 2 and 5, the visible wooden vertical frame 14b2 is fixed to the visible wooden vertical frame fixing piece 14a8 of the metal vertical frame 14a via a large resin spacer 46 and wood tapping screws 42, while the concealed wooden vertical frame 14b1 is fixed to it by an L-shaped fixing bracket 14b4 and wood tapping screws 42.

[0050] In other words, the wooden composite sash of this embodiment 1 is an outward-moving single-sliding window, and the interior fixed sash 3 is fixed to the window frame 1. Therefore, there is no vertical frame on the interior right side of the interior fixed sash 3, and the interior right side of its double-glazed glass portion 25 is directly fixed to the visible wooden vertical frame 14b2 of the right vertical frame 14 with wood tapping screws 42 or the like. The visible wooden vertical frame 14b2 of the vertical frame 14 also functions as the interior right side vertical frame of the interior fixed sash 3.

[0051] As a result, when remodeling the window frame 1, such as changing the design or performing maintenance, the wooden composite vertical frame 14b on the right side of the interior view cannot be removed by removing the L-shaped fixing bracket 14b4 that secures the concealing wooden vertical frame 14b1 and the visible wooden vertical frame 14b2 with wood tapping screws 42. This is different from the wooden composite vertical frame 13b on the left side of the interior view. Instead, the visible wooden vertical frame 14b2 can be removed together with the interior-side fixed sash 3 by pulling it outwards from the concealing wooden vertical frame 14b1.

[0052] <Outdoor movable sliding door 2> As shown in Figures 1 and 2, the exterior movable sash 2 is constructed by providing a double-glazed section 25 with three panes of glass spaced at predetermined intervals in an opening surrounded by an upper frame 21, a lower frame 22, a door edge frame 23, and a meeting stile 24.

However, unlike the wooden bottom frame 22b of the exterior movable shoji screen 2, the wooden bottom frame 32b is fixed to the concealing wooden bottom frame 12b1 and the visible wooden bottom frame 1b2 that constitute the bottom frame 12b by tapping screws 42 for wood, as shown in Figures 6 and 9, etc.

[0097] Furthermore, as shown in Figures 2 and 4, the meeting stile 33 is composed of a metal meeting stile frame cover 33a made of aluminum or the like, and a wooden meeting stile 33b made of decorative wood (frame material) or the like.

[0098] As shown in Figures 2 and 4, the metal meeting stile frame cover 33a is provided on the outdoor side of the movable sash 2 and has a smoke-return piece 33a1 that overlaps with the smoke-return piece 24a5 of the metal meeting stile frame cover 24a of the meeting stile 24 when the outdoor side of the movable sash 2 is closed, and a wooden meeting stile fixing piece 33a2 that bends 90 degrees from the smoke-return piece 33a1 and extends toward the indoor side to fix the wooden meeting stile frame 33b with wood tapping screws 42. The wooden meeting stile fixing piece 33a2 is provided with a groove 33a3 for attaching a trim material into which the locking portion 44a of the trim material 44 fits, and is also provided with an airtight material attachment fitting part 33a4 into which an airtight material 43 that abuts against the back side (indoor side) of the outdoor side of the movable sash 2 is attached.

[0099] Here, the wooden meeting stile fixing piece 33a2 of the metal meeting stile frame cover 33a of the indoor fixed shoji screen 3 also has, similar to the wooden lower frame fixing piece 32a12 of the metal lower frame cover 32a of the indoor fixed shoji screen 3, for example, five screw holes are provided in the longitudinal direction through which wood tapping screws 42 that fix the wooden meeting stile frame 33b pass. Of the five screw holes, only the central screw hole is a round hole with an inner diameter approximately the same as the outer diameter of the wood tapping screw 42, while the other four screw holes are for the wooden meeting stile fixing piece 33 The metal meeting stile frame cover 33a is designed to release thermal expansion in the longitudinal direction at both ends, with elongated holes (so-called loose holes) in the longitudinal direction of a2. Small rubber spacers 49 made of elastomer or other rubber are used to secure the wooden meeting stile frame cover 33b to the wooden meeting stile frame cover 33a. Three screw holes sandwiched between the screw holes at both ends are used to secure the wooden meeting stile frame cover 33b to the wooden meeting stile frame cover 33a to the wooden meeting stile frame cover 33a via small resin spacers 47 made of synthetic resin, which are harder than the small rubber spacers 49, and are also used with wood tapping screws 42.

[0100] As shown in Figures 2 and 4, the wooden meeting stile 33b has a wooden meeting stile side fixing part 33b1 which is fixed to the meeting stile fixing piece 33a2 of the metal meeting stile stile frame cover 33a, and a double-glazed glass receiving part 33b2 which receives the left side of the interior view of the double-glazed glass part 35 via an airtight material 43.

[0101] (Metal tapping screws 41 and wood tapping screws 42) The metal tapping screws 41 are used to fasten metal upper frames 11a and lower frames 12a to metal vertical frames 13a, 14a, and other metal profiles. The wood tapping screws 42 are used to fasten metal members to wood, or to wood members to wood.

[0102] (Airtight material 43) The airtight seal 43 is a well-known component made of a soft synthetic resin such as rubber, and is attached to the fitting portion 11a54 for attaching the airtight seal on the upper metal frame 11a and the fitting portion 12a54 for attaching the airtight seal on the lower metal frame 12a, etc., as shown in Figures 6 to 8, to ensure airtightness with the movable sash 2 on the outside.

[0103] (Folding material 44) The trim material 44 is a member that holds down the double-glazed glass section 25 and the double-glazed glass section 35 on the exterior movable sash 2 and the interior fixed sash 3, respectively, and is formed from a metal profile such as aluminum, similar to the various metal frame covers such as the metal upper frame cover 21a, the metal door edge frame cover 23a, and the metal meeting stile vertical frame cover 33a.

[0104] (Rotation prevention member 45) The anti-rotation member 45 is provided on the metal upper frame cover 21a and the metal lower frame cover 22a, which are metal horizontal frame covers, and a metal tapping screw 41 that penetrates the metal door edge frame cover 23a and the metal meeting frame cover 24a, which are metal vertical frame covers, is tapped through one tapping hole 21a11 in the metal upper hollow part 21a1 or one tapping hole 22 in the wooden lower frame fixing piece part 22a3 of the metal lower frame cover 22a When screwing into a31, this member prevents the metal upper frame cover 21a and metal lower frame cover 22a from rotating together with the metal door edge frame cover 23a and metal meeting frame cover 24a. As described later, it is attached with adhesive to the inner surface (indoor side) of the metal upper hollow portion 21a1 of the metal upper frame cover 21a and the inner surface (indoor side) of the outdoor exposed surface portion 22a1 of the metal lower frame cover 22a.

[0105] The anti-rotation member 45 is made of a resin or metal piece formed in the shape shown in Figures 12(a) to (c). In a front view, it is configured as an L-shape with a rectangular anti-rotation member body 45a and an anti-rotation member bent piece 45b protruding from one end of the anti-rotation member body 45a so as to bend at a 90-degree angle. The outer surface portion 45a1 of the anti-rotation member body 45a is attached to the indoor side surface 22a11 of the outdoor exposed surface portion 22a1 of the metal lower frame cover 22a of the lower frame 2, and to the outdoor exposed surface portion of the upper frame cover 21a of the metal upper frame cover 21a, as shown in Figures 13, 14(b), 15(b), etc., using adhesive or double-sided tape.

[0106] The amount of protrusion W1 of the anti-rotation member's bent portion 45b (see Figure 12(a)) is formed to be the same as or slightly smaller than the width W2 of the groove portion 23a3 for attaching the trim material of the metal door frame cover 23a (see Figure 14(b)), and the height H1 of the anti-rotation member 45 (see Figure 12(b)) is formed to be at least greater than the length L1 of the cut in the indoor side piece portion 23a32 for holding down the trim material that constitutes the groove portion 23a3 for attaching the trim material of the metal door frame cover 23a (see Figure 13).

[0107] As a result, the upper and lower ends of the anti-rotation member's bent portion 45b are brought close to the indoor portion 23a32 for retaining the trim material, as shown in Figure 14(b). When the metal tapping screw 41 penetrates the screw hole of the wooden door frame fixing portion 23a4 of the metal door frame cover 23a, which is a metal vertical frame cover, and is screwed into the tapping hole 22a31 of the wooden lower frame fixing portion 22a3, the upper and lower ends of the anti-rotation member's bent portion 45b of the anti-rotation member 45 come into contact with the outdoor exposed surface portion 23a31 or the indoor portion 23a32 for retaining the trim material, which constitute the groove portion 23a3 for mounting the trim material, thereby preventing the metal lower frame cover 22a and the metal door frame cover 23a from rotating together.

[0108] Here, the reason why a slit is provided in the interior side piece 23a32 for pressing down the trim material, which constitutes the groove portion 23a3 for attaching the trim material, and why these interior side pieces 23a32 for pressing down the trim material are provided at intervals above and below, is that if no slit is provided in the interior side piece 23a32 for pressing down the trim material, the metal door frame cover 23a will interfere with the tapping hole 22a31 of the metal bottom frame cover 22a, and this is to prevent that interference.

[0109] Furthermore, as shown in Figures 12(a) to (c), the anti-rotation member 45 is configured in a plan view as an L-shape, having an anti-rotation member body 45a and an anti-rotation member bent piece 45b. As shown in Figure 14(b), it is formed so as not to completely block the opening of the drainage slit 22a33 of the wooden lower frame fixing piece 22a3 of the metal lower frame cover 22a, ensuring a sufficient gap, so that even with the anti-rotation member 45 installed, rainwater and condensation that fall from the double-glazed glass section 25 can be reliably drained downwards through the drainage slit 22a33.

[0110] (Installation of the anti-rotation member 45 and its function, etc.) The anti-rotation member 45 is attached to the metal bottom frame cover 22a on the indoor side surface 22a11 of the end of the metal door frame cover 23a on the outdoor exposed surface 22a1 of the metal bottom frame cover 22a, as shown in Figures 13 to 15, and as shown in Figure 13, etc., its height in the vertical direction is inserted into the vertical cutout of the indoor side piece 23a32 for holding down the trim in the groove 23a3 for attaching the trim in the metal door frame cover 23a.

[0111] In this case, the trim material 44, which fits into the groove 23a3 for attaching the trim material of the metal door frame cover 23a and presses down on the left side of the interior view of the double-glazed glass section 25, is provided only above the trim material 44 that fits into the trim fitting projection 22a2 of the metal lower frame cover 22a and presses down on the lower side of the double-glazed glass section 25, as shown in Figures 13 and 15(b). It is not provided in the groove 23a3 for attaching the trim material of the metal door frame cover 23a below the lower end of the double-glazed glass section 25.

[0112] Therefore, the groove portion 23a3 for attaching the trim material of the metal door frame cover 23a below the lower end of the double-glazed section 25 is not used and remains empty. As shown in Figures 13 and 14(b), the anti-rotation member 45 is attached to the indoor side surface 22a11 of the end of the metal door frame cover 23a on the metal door frame cover 23a side of the lower frame cover 22a using adhesive or the like, so that the anti-rotation member bent piece 45b fits between the outdoor exposed surface portion 23a31 and the indoor side portion 23a32 for holding down the trim material that constitute the groove portion 23a3 of the metal door frame cover 23a.

[0113] As a result, as shown in Figures 13 and 15(b), the height H1 of the anti-rotation member 45 (see Figure 12(b)) is greater than at least the length L1 of the cut in the indoor side piece 23a32 for retaining the trim material, which constitutes the groove 23a3 for attaching the trim material of the metal door frame cover 23a (see Figure 13). Therefore, as shown in Figure 16, when the metal bottom frame cover 22a attempts to rotate clockwise together with the metal tapping screw 41 that is screwed into the tapping hole 22a31, the anti-rotation member bent piece 45b of the anti-rotation member 45 The upper part of the anti-rotation member 45 abuts against the upper side of the groove 23a3 for attaching the trim material of the metal door frame cover 23a, which forms the groove 23a3 for attaching the trim material, preventing it from rotating together. On the other hand, if the metal lower frame cover 22a attempts to rotate together with the metal tapping screw 41 in a counterclockwise direction, the lower part of the anti-rotation member bent piece 45b of the anti-rotation member 45 abuts against the lower side of the groove 23a32 for attaching the trim material of the metal door frame cover 23a, which forms the groove 23a3 for attaching the trim material, preventing it from rotating together.

[0114] Therefore, when the metal tapping screw 41 is screwed through the screw hole in the wooden door frame fixing piece 23a4 of the metal door frame cover 23a into the tapping hole 22a31 of the wooden bottom frame fixing piece 22a3 of the metal bottom frame cover 22a, even if the metal bottom frame cover 22a tries to rotate together, as shown in Figure 16, the upper and lower ends of the rotation prevention member bent piece 45b of the rotation prevention member 45 come into contact with the outdoor exposed surface portion 23a31 or the indoor side portion 23a32 for pressing down the trim material, which constitute the trim material mounting groove portion 23a3, thereby preventing the metal bottom frame cover 22a from rotating together and allowing the metal bottom frame cover 22a and the metal door frame cover 23a to be joined.

[0115] As described above, in the wooden composite sash of the embodiment according to the present invention, the metal vertical frame cover, which is the metal door frame cover 23a and the metal meeting frame cover 24a, each has a door frame cover side fixing piece 23a4 and a meeting frame cover side fixing piece 24a4 through which metal tapping screws 41 pass toward the metal door frame cover 23a and the metal meeting frame cover 24a, respectively, while the metal horizontal frame cover, which is the metal bottom frame cover 22a, has metal tapping screws 4 that pass through the metal door frame cover 23a and the metal meeting frame cover 24a. The metal door frame cover 23a and the metal door frame cover 24a have tapping holes 22a31 into which a metal tapping screw 41 is screwed and fixed, and the metal door frame cover 22a has a rotation prevention member 45 that, when a metal tapping screw 41 is screwed in and rotates together with the metal tapping screw 41, comes into contact with the metal door frame cover 23a or the metal door frame cover 24a to prevent the metal door frame cover 22a from rotating relative to the metal door frame cover 23a or the metal door frame cover 24a.

[0116] Therefore, when a metal tapping screw 41 is driven through the screw hole in the wooden door frame fixing piece 23a4 of the metal door frame cover 23a and screwed into the tapping hole 22a31 of the wooden bottom frame fixing piece 22a3 of the metal bottom frame cover 22a, the upper and lower ends of the anti-rotation member bent piece 45b of the anti-rotation member 45 come into contact with the outdoor exposed surface portion 23a31 or the indoor side portion 23a32 for pressing down the trim material, which constitute the groove portion 23a3 for attaching the trim material, thereby preventing the metal bottom frame cover 22a from rotating together, and improving the ease of assembly and assembly accuracy of the metal frame covers such as the metal bottom frame cover 22a and the metal door frame cover 23a.

[0117] In particular, in the wooden composite sash according to the embodiment of the present invention, a rotation prevention member 45 that prevents the metal bottom frame cover 22a and the metal door edge frame cover 23a from rotating together is attached to the inner surface (indoor side) of the outdoor exposed surface portion 22a1 of the metal bottom frame cover 22a, which is the end on the metal door edge frame cover 23a side, and the rotation prevention member bent piece portion 45b of the rotation prevention member 45 is fitted between the outdoor side portion 23a31 and the indoor side portion 23a32 for pressing down the trim material, which constitute the groove portion 23a3 for attaching the trim material.

[0118] Therefore, at the joint between the metal bottom frame cover 22a and the metal door frame cover 23a, a groove 23a3 for mounting the trim material 44 is used, and a rotation prevention member 45 is inserted into the groove 23a3 for mounting the trim material 44 to prevent the metal bottom frame cover 22a and the metal door frame cover 23a from rotating together. This efficiently prevents the metal bottom frame cover 22a and the metal door frame cover 23a from rotating together, improving the ease of assembly and assembly accuracy of the metal frame covers.

[0119] Furthermore, in the wooden composite sash according to the embodiment of the present invention, the anti-rotation member 45 is configured in a plan view in an L-shape, having an anti-rotation member body 45a and an anti-rotation member bent piece 45b, as shown in Figures 12(a) to (c). Moreover, as shown in Figure 14(b), even when attached to the inner surface (indoor side) 22a1 of the outdoor exposed surface 22a1 of the lower frame cover, it is formed to a size that ensures a sufficient gap without completely blocking the opening of the drainage slit 22a33 of the wooden lower frame fixing piece 22a3 of the metal lower frame cover 22a. Therefore, even with the anti-rotation member 45 installed, it is possible to prevent obstruction of the drainage function that reliably directs rainwater, condensation, etc., falling from the double-glazed glass section 25 downwards and drains them to the outside.

[0120] In the above embodiment, the anti-rotation member 45 provided on the metal door edge frame cover 23a side of the metal lower frame cover 22a was illustrated and explained. Similarly, by providing the same anti-rotation member 45 on the metal meeting frame cover 24a side of the metal lower frame cover 22a, and also on both sides of the metal door edge frame cover 23a and the metal meeting frame cover 24a of the metal upper frame cover 21a, the profiles of the metal frame covers are prevented from rotating together when fixed to each other with a single metal tapping screw 41.

[0121] Furthermore, although the above description of the embodiment used an outward-moving single-sliding window as an example, the present invention is not limited to outward-moving single-sliding windows, but can also be applied to sliding windows, inward-moving single-sliding windows, and even wooden composite sashes and wooden composite sashes such as casement windows, outward-opening windows, double-opening windows, and fixed windows (non-opening windows).
