[0007] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figures 1 to 5 show a first embodiment of a sash according to the present invention. This sash is applied to a sliding sash for a wooden house, and as shown in Figures 2 and 3, it includes a sash frame 1 attached to a frame opening 7, an outer shoji screen 8a and an inner shoji screen 8b provided within the sash frame 1 so as to be able to open and close freely in a sliding manner, and a screen door 9 provided on the outside of the outer shoji screen 8a so as to be able to slide along upper and lower frames 10 and 11.
[0008] As shown in Figures 2 and 3, the sash frame 1 is made up of an upper frame 10, a lower frame 11, and left and right vertical frames 2, 2, all of which are made of extruded aluminum alloy. The sash frame 1 is a so-called semi-external frame, and fins 13 for fixing to the main body 12 protrude outward at a midpoint between the indoor and outdoor sides, and these fins 13 are fixed to the main body 12 with screws 15 from the outside of the room. Furthermore, the upper frame 10 and vertical frames 2 are fixed to the main body 12 at a position closer to the indoor side of the visible wall 14 with screws 16 from the inside. The vertical and horizontal dimensions of the sash frame 1 are slightly smaller than those of the body opening 7, and when the sash frame 1 is placed in the body opening 7, gaps are created between the left and right vertical frames 2, 2 and the side edges 7a of the body opening 7, and between the upper frame 10 and the upper edge 7b of the body opening 7.
[0009] As shown in Figure 1, the vertical frame 2 has protruding pieces 17 that protrude outward from the indoor end of the visible wall 14 and from a position a short distance from the indoor end to the outdoor side. The left-to-right dimension W1 of the skeleton opening 7 is precisely the same as in the design drawings, and a certain gap S, for example a gap S of 3 mm, is formed between the side edge 7a of the skeleton opening 7 and the protruding pieces 17 of the vertical frame 2. The left-to-right dimension W2 of the sash frame 1 is the left-to-right dimension W1 of the skeleton opening 7 minus 2 x S.
[0010] As shown in Figure 1, a spacer 3 is attached to the outer periphery side of the visible wall 14 of the vertical frame 2. The spacer 3 is formed by cutting an extruded aluminum alloy profile to a predetermined length (for example, 40 mm), and has an attachment portion 4 that adheres to the outer periphery side of the visible wall 14 of the vertical frame 2, a body-facing portion 5 that faces the side edge 7a of the body opening 7, and one connecting portion 18 that connects the attachment portion 4 and body-facing portion 5 at the center in the forward direction, and has a generally H-shaped cross section that is symmetrical from front to back and has no hollow portion. The body facing portion 5 has guide portions 6 at the indoor and outdoor ends that are inclined at an angle of 45° toward the inner periphery, and the tip of the guide portion 6 is bent toward the inner periphery. The spacer 3 has a thickness T of 9 mm, and the body-facing portion 5 protrudes a predetermined distance S1 from the protruding piece 17 of the vertical frame 2 toward the outer periphery, forming a small gap S2 between the side edge 7a of the body opening 7 and the body-facing portion 5. Specifically, S1 is set to, for example, 2 mm, and S2 is set to 1 mm.
[0011] As shown in Figure 1, the spacers 3 are attached along the longitudinal direction of the vertical frame 2 at a position adjacent to the outdoor side of the protrusion 17 at the indoor end of the vertical frame 2. Furthermore, as shown in Figures 4 and 5, a plurality of spacers 3 are arranged at a predetermined pitch (for example, 400 to 600 mm) along the longitudinal direction of the vertical frame 2 above or below the holes 19 through which the screws 16 for fixing to the frame 12 are inserted. The spacer 3 has double-sided tape already attached to the inner peripheral side surface of the attachment portion 4, and when attaching it to the vertical frame 2, it can be easily attached by peeling off the release paper on the side opposite to the side of the double-sided tape attached to the attachment portion 4, and adhering the attachment portion 4 to the outer peripheral side surface of the recessed wall 14 of the vertical frame 2 with the double-sided tape. The spacer 3 is symmetrical from front to back, so there is no need to worry about the front-to-back orientation.
[0012] As shown in Figure 4, a waterproof sheet 20 is provided in the gap between the lower part of the vertical frame 2, the outer peripheral side surface of the bottom frame 11, and the skeleton opening 7. The waterproof sheet 20 is attached to the skeleton 12 side before the sash frame 1 is placed in the skeleton opening 7.
[0013] Next, the installation procedure for this sash will be explained. First, the spacers 3, 3, ... are attached to the predetermined positions on the outer periphery of the left and right vertical frames 2, 2 of the pre-framed sash frame 1 using double-sided tape. Next, the sash frame 1 with the spacers 3, 3, ... attached is placed into the frame opening 7 from the outside of the room, as shown in Figure 6. At this time, the sash frame 1 is positioned in the vertical direction by placing the bottom frame 11 on the lower edge 7c of the frame opening 7, as shown in Figure 3, and the sash frame 24 is inserted into the gap between the top frame 10 and the upper edge 7b of the frame opening 7 from the inside of the room. When the sash frame 1 is placed in the frame opening 7, as shown in Figures 1 and 2, the frame-facing portion 5 of each spacer 3 abuts or comes close to the side edge 7a of the frame opening 7, thereby positioning the sash frame 1 in the center of the frame opening 7. Therefore, there is no need to insert braces in the gaps between the left and right vertical frames 2, 2 and the side edges 7a of the frame opening 7. When fitting the sash frame 1 into the structural opening 7 from the outside, if the sash frame 1 is biased to either the left or right side, the guide portion 6 provided on the indoor side of the structural body-facing portion 5 of the spacer 3 will abut against the outdoor corner 21 (see Figure 1) of the structural opening 7, and as the sash frame 1 moves indoors, the sash frame 1 will be guided to the center position of the structural body opening 7. Therefore, the sash frame 1 can be fitted smoothly into the structural body opening 7 without getting stuck in the outdoor corner 21 of the structural body opening 7, making it difficult to fit the sash frame 1, or damaging the structural body 12. When the sash frame 1 is placed into the structural opening 7 from the outside, the spacers 3, 3, ... allow the sash frame 1 to be naturally positioned in the center of the structural opening 7, eliminating the need to adjust the left-right position of the sash frame 1 later. Instead, the sash frame 1 can be fixed to the structural body 12 with screws 15, 16 by simply inserting a brace 24 into the gap between the upper frame 10 and the upper edge 7b of the structural opening 7, thereby improving workability. Thereafter, in the same manner as in the case of a normal sash, an exterior wall material 22 is installed on the exterior side of the room, and the gap between the exterior wall material 22 and the sash frame 1 is sealed with a sealant 23 (see FIGS. 2 and 3). Thereafter, the outer shoji screen 8a, the inner shoji screen 8b, and the screen door 9 are installed into the sash frame 1.
[0014] According to this sash manufacturing method, the sash frame 1 can be simply placed into the main body opening 7 from the outside of the room, and the spacers 3, 3, ... allow the sash frame 1 to be positioned in the center of the main body opening 7, thereby improving workability. In this sash, the spacers 3 are made of metal and do not deform, so the position of the sash frame 1 can be accurately adjusted when the sash frame 1 is placed in the frame opening 7. In addition, because the spacers 3 are made of metal, they will not burn in the event of a fire, which is advantageous in terms of fire prevention. The spacer 3 is made from an extruded aluminum alloy profile, so it can be manufactured with high precision and at low cost. Moreover, because the spacer 3 is a profile without a hollow portion, it can be easily extruded and material costs can be reduced. Furthermore, because the spacer 3 is symmetrical from front to back, it can be installed without worrying about the front-to-back orientation. The spacer 3 can further reduce material costs by connecting the attachment portion 4 and the body-facing portion 5 with a single connecting portion 18 at the center position in the prospective direction.
[0015] 7 to 9 show a second embodiment of the sash according to the present invention. As shown in Figs. 8 and 9, the sash of the second embodiment differs from that of the first embodiment in the cross-sectional shape of the spacer 3. The spacer 3 is made of an extruded aluminum alloy material, and has a thickness T of 5.5 mm, which is thinner than that of the first embodiment. The spacer 3 has a roughly C-shaped cross section that is symmetrical from front to back and has no hollow portion, and has an attachment portion 4 that adheres to the outer peripheral side of the projection wall 14 of the vertical frame 2, a body-facing portion 5 that faces the side edge 7a of the body opening 7, and a connecting portion 18 that connects the attachment portion 4 and body-facing portion 5 on the indoor and outdoor sides. The body-facing portion 5 is discontinued in the center in the projection direction, and has guide portions 6 that are inclined toward the inner periphery on both the indoor and outdoor sides of the body-facing portion 5.
[0016] As with the first embodiment, the sash of the second embodiment has spacers 3, 3, ... attached to the outer side surfaces of the vertical frames 2, 2, and then the sash frame 1 is placed into the main body opening 7 from the outside of the room.This allows the spacers 3, 3, ... to position the sash frame 1 in the center of the main body opening 7, improving workability.
[0017] As described above, in the manufacturing method of this sash, spacers 3, 3, ... are attached to the outer peripheral side surfaces of the left and right vertical frames 2, 2 of the sash frame 1, and the spacers 3 are made of metal and have an attachment portion 4 that adheres to the outer peripheral side surface of the vertical frame 2 and a body-facing portion 5 that faces the side edge 7a of the body opening 7, and the body-facing portion 5 has a guide portion 6, and the sash frame 1 with the spacers 3, 3, ... attached is placed into the body opening 7 and the body-facing portions 5 of the spacers 3, 3, ... are brought into contact with or close to the side edge 7a of the body opening 7, thereby positioning the sash frame 1 in the center of the body opening 7 (see Figures 1, 2, 7, 8), which eliminates the need to adjust the left-right position of the sash frame 1 after placing the sash frame 1 in the body opening 7, thereby improving workability. Since the spacer 3 is made of metal, the position of the sash frame 1 can be adjusted accurately when the sash frame 1 is placed in the frame opening 7, and the spacer 3 does not burn in the event of a fire, which is advantageous in terms of fire prevention. The spacer 3 is made of shaped material and has an attachment portion 4, a body-facing portion 5, and a connecting portion 18 connecting the attachment portion 4 and the body-facing portion 5 (see Figures 1 and 8), so it is easy to attach to the sash frame 1, has excellent shape stability, and can reduce material costs. In particular, if the spacer 3 has a roughly H-shaped cross section with one connecting portion 18 in the center in the projection direction (see Figure 1), material costs can be reduced when the thickness T of the spacer 3 is relatively thick. If the spacer 3 has a roughly C-shaped cross section with the body-facing portion 5, which is interrupted in the center in the projection direction, connected by the attachment portion 4 and connecting portion 18 on the outside and inside of the room (see Figure 8), material costs can be reduced when the thickness T of the spacer 3 is relatively thin. The spacer 3 is formed from a front-to-back symmetrical profile (see Figures 1 and 8), so it can be attached to the vertical frame 2 without having to worry about the front-to-back orientation, further improving workability. The spacer 3 is formed from a shape material that does not have a hollow portion (see FIGS. 1 and 8), so that the extrusion process is easy and the material cost can be reduced.
[0018] The present invention is not limited to the above-described embodiments. The cross-sectional shape and material of the frame material constituting the sash frame can be modified as appropriate. The shape, material, and installation method of the spacer can be modified as appropriate. The guide portion of the spacer can be formed in any specific form as long as it can guide the sash frame to the center position of the opening in the main frame when the sash frame is inserted into the opening in the main frame. The guide portion may also be provided only on the interior side of the opposing main frame portion. The sash frame may be inserted into the opening in the main frame from the interior side. The present invention is not limited to sliding windows, but can be applied to all window types, such as sliding windows, pivot windows, and fixed windows. [Explanation of symbols]
