Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, since the coefficient of thermal expansion is different between wooden parts such as wooden vertical frames and wooden horizontal frames and metal parts such as metal vertical covers and metal horizontal covers made of aluminum, etc., there is a problem that warping and bending occur due to thermal expansion and contraction between the metal vertical cover and the metal horizontal cover that face the outdoor side and are exposed to direct sunlight, and the wooden members such as the wooden vertical frame and the wooden horizontal frame that face the indoor side.

[0005] In particular, wooden composite shoji screens installed on the south side, which are exposed to direct sunlight, are prone to warping and bending during the summer months. This is because the outside temperature itself becomes considerably high, while the indoor temperature is lowered by air conditioning, resulting in a large temperature difference.

[0006] Therefore, the present invention was made to solve these problems, and aims to provide a wooden composite shoji screen and wooden composite sash that are less prone to bending or warping due to the difference in thermal expansion coefficients between the wooden and metal parts. [Means for solving the problem]

[0007] 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 covers, and upper and lower horizontal frames having wooden horizontal frames and metal horizontal covers, wherein the metal vertical cover and metal horizontal cover are provided at multiple locations on both ends of the metal vertical cover and metal horizontal cover, and in the intermediate part between the ends, for fixing the metal vertical cover and metal horizontal cover by screwing them into the wooden vertical frame and the wooden horizontal frame, respectively, and spacers are provided between the fixing pieces at multiple locations on the metal vertical cover and metal horizontal cover and the wooden vertical frame or the wooden horizontal frame. Furthermore, the wooden composite shoji screen according to the present invention is also characterized in that, among the multiple fixing pieces of the metal vertical cover and the metal horizontal cover, rubber spacers are provided on the fixing pieces that are close to the corners of the glass portion which are both ends of the metal vertical cover and the metal horizontal cover, while resin spacers are provided on the intermediate fixing pieces that are sandwiched between the fixing pieces that are close to the corners of the glass portion which are both ends of the metal vertical cover and the metal horizontal cover. Furthermore, the wooden composite shoji screen according to the present invention is also characterized in that wooden frame corner reinforcing fittings are provided at the corners between the wooden vertical frame and the wooden horizontal frame, which are reinforced by screwing screws into the wooden vertical frame and the wooden horizontal frame. Furthermore, the wooden composite sash according to the present invention is characterized in that one of the above-mentioned wooden composite sashes 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]

[0008] In the wooden composite shoji screen according to the present invention, resin or rubber spacers are provided between the wooden vertical frame or wooden horizontal frame and the fixing pieces at multiple locations that fix the wooden vertical frame or wooden horizontal frame of the metal vertical cover and the metal horizontal cover, respectively. Therefore, even if the thermal expansion coefficients differ between the wooden part of the wooden vertical or horizontal frame and the metal part of the metal vertical and horizontal covers, the spacer expands and contracts to absorb the difference in expansion coefficients, thus preventing deflection caused by the difference in thermal expansion coefficients between the wooden and metal parts.

[0048] As shown in Figures 2 and 5, the visible wooden vertical frame 14b2 is fixed to its outer surface with wood tapping screws 42 that pass through the concealing wooden vertical frame fixing piece 14a6 of the metal vertical frame 14a, while an L-shaped fixing bracket 14b4 is provided which is fixed to the concealing wooden vertical frame 14b1 and the visible wooden vertical frame 14b2 with wood tapping screws 42.

[0049] 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.

[0050] 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.

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.

[0098] 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.

[0099] 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.

[0100] (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.

[0101] (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.

[0102] (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.

[0103] (Large resin spacer 46) The large resin spacers 46 are synthetic resin spacers formed in the shape shown in Figures 12(a) to (d), with a screw hole 46a in the center through which a wood tapping screw 42 is passed. As shown in Figure 14, multiple spacers (for example, three) are provided at intervals away from the corners of each frame of the outdoor movable sash 2 and the indoor fixed sash 3.

[0104] Specifically, on the exterior movable sliding door 2, as shown in Figures 6, 7, 14, and the simplified Figures 15 and 16, large resin spacers 46 are provided by inserting three of these spacers at intervals along the longitudinal direction of the frame, as in the case of the metal frame cover 23a of the frame 23 shown in Figure 17(b), and fixing them with tapping screws 42 for woodworking, between the wooden frame fixing piece 21a3 of the metal frame cover 21a of the upper frame 21 and the wooden frame 21b, between the wooden frame fixing piece 23a4 of the metal frame cover 23a of the metal frame cover 24a of the meeting frame 24 and the wooden frame 24b, as in the case of the metal frame cover 23a of the frame 23 shown in Figure 17(b). As will be explained in more detail later, at both ends of the metal door frame cover 23a and the metal meeting stile cover 24a, a large rubber spacer 46, as described later, is provided instead of the large resin spacer 46.

[0105] Furthermore, as shown in Figures 4, 14, 15, and 16, the indoor fixed shoji screen 3 is provided with large resin spacers 46, which are inserted in groups of three at intervals along the longitudinal direction of the frames and frames, and fixed with tapping screws 42 for woodworking, between the wooden meeting mullion fixing piece 33a2 of the metal meeting mullion frame cover 33 and the wooden meeting mullion 33b, and between the visible wooden vertical frame fixing piece 14a8 of the metal vertical frame 14a of the right vertical frame 14 and the wooden vertical frame 14b.

[0106] (Small resin spacer 47) The small resin spacers 47 are made of synthetic resin, similar to the large resin spacers 46 which are formed in the shape shown in Figures 13(a) to (d). The small resin spacers 47 are smaller in size than the large resin spacers 46 and have a screw hole 47a in the center through which a wood tapping screw 42 is passed. As shown in Figure 14, multiple spacers (for example, three in this case) are provided at intervals away from the corners of each frame of the outdoor movable sash 2 and the indoor fixed sash 3.

[0107] Specifically, the small resin spacers 47 are installed on the outdoor movable sash 2 by inserting three spacers at intervals along the longitudinal direction of the sash 22 between the wooden sash fixing piece 22a3 of the metal sash cover 22a of the sash 22 and the wooden sash 22b, as shown in Figures 6, 8, 14, and 16, and then fixing them with tapping screws 42 for woodworking.

[0108] Furthermore, on the interior fixed shoji screen 3, as shown in Figures 9, 10, 11, 14, and 16, small resin spacers 47 are provided by inserting three of them at intervals along the longitudinal direction of the upper frame 31 and lower frame 32, similar to the case of the metal lower frame cover 32a of the lower frame 32 shown in Figure 18(b), between the wooden upper frame fixing piece 31a12 of the metal upper frame 31a of the upper frame 31 and between the wooden lower frame fixing piece 32a12 of the metal lower frame cover 32a of the lower frame 32 and the wooden lower frame 32b, and fixing them with tapping screws 42 for woodworking.

[0109] (Large rubber spacer 48) The large rubber spacer 48 differs from the large resin spacer 46 described above only in its material; it is made of a softer rubber such as elastomer, and as shown in Figures 12(a) to (d), it is formed to be the same size and shape as the large resin spacer 46, and has a screw hole 48a in the center through which a wood tapping screw 42 is passed.

[0110] Unlike the large resin spacer 46, the large rubber spacer 48 is installed on the outdoor movable sash 2 near the corners of the frames at both ends of the upper frame 21, door edge frame 23, and meeting frame 24, that is, near the corners of the double-glazed glass section 25, and is inserted between the wooden upper frame fixing piece 21a3 of the metal upper frame cover 21a and the wooden upper frame 21b of the outdoor movable sash 21, between the wooden door edge frame fixing piece 23a4 of the metal door edge frame cover 23a and the wooden door edge frame 23b, and between the wooden meeting frame fixing piece 24a4 of the metal meeting frame cover 24a and the wooden meeting frame 24b of the meeting frame 24, and is fixed with tapping screws 42 for woodworking.

[0111] Furthermore, on the interior fixed sash 3, as shown in Figure 19, large rubber spacers 48 are provided near the corners of the frames, which are the ends of the meeting stile 33 and the vertical frame 14, that is, near the corners of the double-glazed glass section 35, and between the wooden meeting stile fixing piece 33a2 of the metal meeting stile stile frame cover 33 and the wooden meeting stile 33b, and between the visible wooden vertical frame fixing piece 14a8 of the metal vertical frame 14a of the right vertical frame 14 and the wooden vertical frame 14b.

[0112] (Small rubber spacer 49) The small rubber spacer 49 is a rubber spacer made of elastomer or the like, similar to the large rubber spacer 48, and is formed to be the same size and shape as the small resin spacer 47, as shown in Figures 13(a) to (d), and is provided with a screw hole 49a in the center through which a wood tapping screw 42 is passed, similar to the small resin spacer 47.

[0113] The small rubber spacer 49 is installed on the outdoor movable sash 2 near the corners of the frame, which are both ends of the bottom frame 22, as shown in Figure 19, that is, near the corners of the double-glazed glass section 25, and between the wooden bottom frame fixing piece 22a3 of the metal bottom frame cover 22a of the bottom frame 22 and the wooden bottom frame 22b, as shown in Figures 6 and 8.

[0114] Furthermore, the interior fixed sash 3 is provided near the corners of the frames, which are both ends of the upper frame 31 and lower frame 32, as shown in Figure 19, that is, near the corners of the double-glazed glass section 35, and between the wooden upper frame fixing piece 31a12 of the metal upper frame 31a of the upper frame 31, and between the wooden lower frame fixing piece 32a12 of the metal lower frame cover 32a of the lower frame 32 and the wooden lower frame 32b.

[0115] Therefore, the upper frames 21, 31, lower frames 22, 32, door-edge frame 23, meeting frame 24, and meeting mullions 33, etc. that constitute the movable sliding door 2 on the outside and the fixed sliding door 3 on the inside of this embodiment, which are wooden composite sliding doors, are composed of wooden upper frames 21b, 31b, wooden lower frames 22b, 32b, wooden door-edge frame 23b, wooden meeting frame 24b, and wooden meeting mullions 33b, respectively, which are made of decorative wood (frame material) or the like, and metal upper frame covers 21a, 21b, metal lower frame covers 22a, 22b, metal door-edge frame cover 23a, metal meeting frame cover 24a, and metal meeting mullion frame cover 33a, etc. that are formed from aluminum or the like and provided on their surface sides, and are composed of wooden members and metal members with different coefficients of thermal expansion. Large and small resin spacers 46, 47 and rubber spacers 48, 49 are provided at predetermined intervals between the metal and wooden members and fixed with wood tapping screws 42. Therefore, even if the surface of the metal member, such as the metal frame cover which is mainly on the outdoor side, is exposed to direct sunlight, or if there is a difference in the degree of thermal expansion or contraction between the metal member and the wooden member due to the temperature difference between the inside and outside, the resin spacers 46, 47 and rubber spacers 48, 49 provided between the metal and wooden members expand and contract to absorb the difference in thermal expansion or contraction between the metal member and the wooden member, thereby preventing bending, warping, etc., of the wooden composite shoji screen, which consists of the outdoor movable shoji screen 2 and the indoor fixed shoji screen 3.

[0116] In particular, in the movable sliding door 2 on the outside and the fixed sliding door 3 on the inside of this embodiment, rubber spacers 48 and 49 are provided at the corners of each frame, which are the ends of the metal upper frame covers 21a and 21b, the metal lower frame covers 22a and 22b, the metal door edge frame cover 23a, the metal meeting frame cover 24a, and the metal meeting vertical frame cover 33a, that is, at the fixing pieces near the corners of the double-glazed glass sections 25 and 35, as shown in Figure 19, etc., while the corners of the double-glazed glass sections 25 and 35 In areas further away from the rubber spacers, as shown in Figure 14, resin spacers 46 and 47, which are harder than the rubber spacers 48 and 49, are provided. As a result, the rubber spacers 48 and 49 can reliably prevent bending, warping, etc., at both ends of the metal upper frame cover 21a, metal lower frame cover 22a, metal door edge frame cover 23a, metal meeting stile frame cover 24a, and metal meeting stile vertical frame cover 33a, where the degree of thermal expansion and contraction is large.

[0117] (Wooden frame corner reinforcement bracket 50) The wooden frame corner reinforcement fitting 50 is an L-shaped fitting as shown in Figures 20(a) to (c), and consists of a pair of fitting fixing plate parts 50a, 50a bent at a 90-degree angle. Each of the fitting fixing plate parts 50a, 50a is provided with two screw holes 50a1 through which wood tapping screws 42 are passed.

[0118] As shown in Figures 21 to 23, this wooden frame corner reinforcement fitting 50 is installed at the corners of both the movable sliding door 2 on the exterior side and the fixed sliding door 3 on the interior side of this embodiment, which is a wooden composite sliding door.

[0119] In other words, in the outdoor movable sliding door 2, as shown in Figures 21 to 23, the metal corner portion 50b of the wooden frame corner reinforcing fitting 50 is positioned at the joints between the wooden upper frame 21b of the upper frame 21 and the wooden lower frame 22b of the lower frame 22, and the wooden front frame 23b of the door frame 23 and the wooden meeting frame 24b of the meeting frame 24. The wooden frames are then fixed together by the wooden frame corner reinforcing fitting 50 by passing wood tapping screws 42 through the two screw holes 50a1 of the metal fixing plate portions 50a, 50a.

[0120] Similarly, in the interior-side fixed shoji screen 3, as shown in Figures 21 to 23, the wooden upper frame 31b of the upper frame 31, the wooden lower frame 32b of the lower frame 32, the wooden meeting mullion 33b of the meeting mullion (meeting frame) 33, and the wooden composite vertical frame 14b of the right vertical frame 14 which also functions as a vertical frame of the interior-side fixed shoji screen 3 are each positioned at the joints, and the corner portion 50b of the wooden frame corner reinforcing fitting 50 is passed through the two screw holes 50a1 of the fitting fixing plate portion 50a, 50a, respectively, to fix the wooden frames together with the wooden frame corner reinforcing fitting 50.

[0121] Therefore, in this embodiment, which consists of a wooden composite shoji screen, the wooden upper frame 21b of the upper frame 21 and the wooden lower frame 22b of the lower frame 22, as well as the wooden leading edge frame 23b of the door frame 23 and the wooden meeting edge frame 24b of the meeting edge frame 24, are not only fixed to their respective metal upper frame cover 21a, metal lower frame cover 22a, metal leading edge frame cover 23a, and wooden meeting edge frame 24b, but are also fixed at each joint between the wooden frames by wooden frame corner reinforcing fittings 50, making it possible to construct the wooden frames that make up the outdoor movable shoji screen 2 in a strong manner.

[0122] In the above description of the embodiment, an outward-moving single-sliding window was used as an example. However, 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).
