[0003] [Patent Document 1] Patent No. 08-068265 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, many house manufacturers procure dedicated window sashes that fit their own house designs from sash manufacturers, and window frames are often designed to match them. However, in recent years, relatively inexpensive general route window sashes may be adopted in order to reduce the cost of the entire building and shorten the construction period. In such cases, if a window sash with a different shape or installation method that does not fit the previous design conditions is adopted, a gap may be formed between the sash frame and the window frame, which is not desirable not only in terms of appearance but also in terms of the impact on the structure due to the edge of the opening being exposed through the gap. In addition, if a new window frame is produced to match the general route product so that such a gap does not form, a new window frame will have to be produced in addition to the dedicated window frame, which may actually increase costs. Therefore, there is a demand for the development of a technology that can successfully fill the gap between the window frame and the sash even when a general route window sash is adopted.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and its purpose is to make it possible to fill a gap that forms between the sash frame and the window frame, for example when a window sash made from a general route product is used, thereby making it possible to reduce the cost of the entire building and shorten the construction period, etc. [Means for solving the problem]

[0006] The invention described in claim 1 is, for example, as shown in Figs. 1 to 8, a structure for fitting a window 3, A window 3 is provided in an opening 2 formed in a wall 1 of a building, The window 3 includes a window sash 10 located on the outdoor side of the edge of the opening 2, and a window frame 20 located on the indoor side of the edge of the opening 2, The window sash 10 has a window screen 11 for opening or closing the opening 2, and a sash frame 12 that holds the window screen 11 in a state in which it can be opened and closed and is fixed to the edge of the opening 2, The sash frame 12 is disposed at a distance from the window frame 20 to the outdoor side, A gap S is formed between the sash frame 12 and the window frame 20. A sash spacer 30 for filling the gap S is attached to the indoor side of the sash frame 12.

[0007] According to the invention described in claim 1, the sash frame 12, which constitutes the window sash 10 together with the window screen 11, is positioned away from the window frame 20 on the outdoor side, forming a gap S between the sash frame 12 and the window frame 20, and a sash spacer 30 for filling such a gap S is attached to the indoor side of the sash frame 12, so that even if a gap S is formed between the sash frame 12 and the window frame 20, for example, when a window sash 10 made from a general route is used, the gap S can be filled by the sash spacer 30. This eliminates the need to manufacture a new window frame to prevent the gap S from being formed between the sash frame 12, which ultimately reduces the cost of the entire building and shortens the construction period.

[0008] The invention described in claim 2 is, for example, as shown in Figs. 4 to 8, in the mounting structure of the window 3 described in claim 1, The sash spacer 30 is A main body portion 31 including a portion sandwiched between the sash frame 12 and the window frame 20 and a portion exposed to the indoor side; and a fixing portion 32 located closer to the edge of the opening 2 than the main body portion 31 and fixed to the sash frame 12. The sash spacer 30 is characterized in that the portion of the main body 31 that is sandwiched between the sash frame 12 and the window frame 20 and the fixing portion 32 are shielded by the window frame 20.

[0009] According to the invention described in claim 2, a portion of the main body 31 of the sash spacer 30 can be exposed to the inside of the room, while another portion of the main body 31 and the fixing portion 32 can be shielded by the window frame 20. This makes it possible to fill the gap S between the sash frame 12 and the window frame 20 while reliably shielding the fixing portion 32, thereby improving the appearance. Furthermore, since the sash spacer 30 has a main body 31 including a portion that is sandwiched between the sash frame 12 and the window frame 20, a portion of the sash spacer 30 is sandwiched between the sash frame 12 and the window frame 20, thereby improving the installation condition of the sash spacer 30.

[0010] The invention described in claim 3 is, for example, as shown in Figs. 4 to 8, in the mounting structure of the window 3 described in claim 2, A recess is formed on the surface of the sash spacer 30 facing the sash frame 12, A portion of the main body 31 that is sandwiched between the sash frame 12 and the window frame 20 and the fixing portion 32 overlap with a range in which the recess is formed, The fixing portion 32 is characterized in that a through hole 32a is formed through which a fixing material is passed.

[0011] According to the invention described in claim 3, since a recess is formed on the surface of the sash spacer 30 facing the sash frame 12, the area of ​​the sash spacer 30 where the recess is formed has a slight elasticity. The part of the main body 31 that is sandwiched between the sash frame 12 and the window frame 20 and the fixing part 32 overlap with the area where the recess is formed, and the fixing part 32 has a through hole 32a through which the fixing material is passed, so that the force of the fixing material being pushed toward the sash frame 12 side can be absorbed. Furthermore, since the main body 31 includes a part that is sandwiched between the sash frame 12 and the window frame 20, the main body 31 is pressed against the sash frame 12 side by the window frame 20. As a result, when the sash spacer 30 is fixed to the sash frame 12 by the fixing material, the upper end of the main body 31 can be prevented from moving away from the rising part 12c.

[0012] The invention described in claim 4 is, for example, as shown in Figs. 2 and 4 to 6, in the mounting structure of the window 3 described in claim 1, The sash frame 12 is provided with a rising portion 12c which is formed in a portion of the body portion of the sash frame 12 which is located on the indoor side and rises from an edge portion of the opening 2 toward a center side of the opening 2, The sash spacer 30 is attached to the indoor side surface of the rising portion 12c, The sash spacer 30 is characterized in that an end face located on the central side of the opening 2 and an end face of the rising portion 12c located on the central side of the opening 2 are flush with each other.

[0013] According to the invention described in claim 4, the end face of the sash spacer 30 located on the central side of the opening 2 and the end face of the rising portion 12c located on the central side of the opening 2 are flush with each other, thereby improving the unity of the rising portion 12c and the sash spacer 30. This allows the gap S formed between the sash frame 12 and the window frame 20 to be filled with the sash spacer 30 in an attractive manner.

[0014] The invention described in claim 5 provides, for example, as shown in Figs. 4 to 6, in the mounting structure of the window 3 described in claim 1, The sash frame 12 includes a fixing piece 12a (first fixing piece 12a) that protrudes from a portion of the body of the sash frame 12 that is located closest to the interior side along the edge of the opening 2 toward the window frame 20 and is fixed to the edge of the opening 2, The window frame 20 is provided with a recess 20a formed at an end of the window frame 20 closest to the sash frame 12 and in which the fixing piece 12a is accommodated, A feature of the present invention is that the bottom of the gap S formed between the sash frame 12 and the window frame 20 is the fixing piece 12a.

[0015] According to the invention recited in claim 5, since the fixing piece 12a of the sash frame 12 is housed in the recess 20a of the window frame 20, impact between the sash frame 12 and the window frame 20 can be prevented. Furthermore, since the bottom of the gap S formed between the sash frame 12 and the window frame 20 is the fixed piece 12a, the sash spacer 30 can be positioned based on the fixed piece 12a, making it easier to install the sash spacer 30.

[0016] The invention described in claim 6 is, for example, as shown in Figs. 1 to 3, a construction method for the window 3 mounting structure described in claim 5, The sash frame 12 is composed of a lower horizontal frame member 121, an upper horizontal frame member 122, a vertical frame member 124 on one side, and a vertical frame member 123 on the other side. The sash spacers 30 include a first sash spacer 30 attached to the lower horizontal frame member 121, a second sash spacer 30 attached to the upper horizontal frame member 122, a third sash spacer 30 attached to the one side vertical frame member 124, and a fourth sash spacer 30 attached to the other side vertical frame member 123. a step of assembling each of the frame members 121 to 124 of the sash frame 12 into a rectangular frame shape, and then attaching the third sash spacer 30 to the vertical frame member 124 on one side; a step of attaching the first sash spacer 30 to the lower horizontal frame member 121 in a state in which the first sash spacer 30 is in contact with a lower end side edge of the third sash spacer 30 and in a state in which the first sash spacer 30 is in contact with the fixing piece 12a of the lower horizontal frame member 121; a step of attaching the second sash spacer 30 to the upper horizontal frame member 122 in a state in which the second sash spacer 30 is in contact with an upper end side edge of the third sash spacer 30 and in a state in which the second sash spacer 30 is in contact with the fixing piece 12a of the upper horizontal frame member 122; The method is characterized by including a step of attaching the fourth sash spacer 30 to the other side vertical frame member 123 after slightly separating the fourth sash spacer 30 from the fixing piece 12a of the other side vertical frame member 123 and bringing the fourth sash spacer 30 into contact with the other side ends of the first sash spacer 30 and the second sash spacer 30.

[0017] According to the invention described in claim 6, when the four sash spacers 30 are arranged in a rectangular frame shape along the sash frame 12 consisting of the four frame members 121 to 124, the first sash spacer 30 and the second sash spacer 30 in the horizontal direction are provided between the third sash spacer 30 and the fourth sash spacer 30 in the vertical direction, that is, in a so-called vertically dominated state. Therefore, even if the sash spacers 30 as a whole sag due to aging, for example, gaps S are unlikely to occur between the sash spacers 30, and good external design is easily maintained even if aging occurs. Furthermore, by performing the construction in the order of installing the third vertical sash spacer 30, then installing the first and second horizontal sash spacers 30, and then installing the fourth vertical sash spacer 30, it is possible to absorb dimensional tolerances that arise when processing the sash spacer 30. Effect of the Invention

[0018] According to the present invention, when a gap forms between the sash frame and the window frame, for example, when a window sash made from a general route product is used, the gap can be filled, thereby reducing the cost of the entire building and shortening the construction period, etc. [Brief description of the drawings]

[Figure 7] FIG. [Figure 8] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the embodiment described below is subject to various limitations that are technically preferable for implementing the present invention, but the technical scope of the present invention is not limited to the following embodiment and illustrated examples. Note that the directions in the following embodiment and illustrated examples are set solely for the convenience of explanation.

[0021] An opening 2 is formed in a wall 1 of a house or a non-house building, and a window 3 is provided in the opening 2 to open or close the opening 2. The window 3 in this embodiment includes a window sash 10 attached to the outdoor side of the opening 2, a window frame 20 attached to the indoor side, and a sash spacer 30 provided between the window sash 10 and the window frame 20.

[0022] In this embodiment, a vertical sliding window that opens to the outside while sliding along grooves provided at the top and bottom is used as the window 3. However, the type of window 3 is not limited to this, and can be changed as appropriate without departing from the spirit of the present invention.

[0023] Fig. 1 is a front view showing a schematic configuration of a window sash 10 constituting such a window 3. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1, and Fig. 3 is a cross-sectional view taken along line III-III in Fig. 1. In Figs. 1 to 3, the components of the window sash 10 are deformed so that the rough shape and position of each component can be recognized. Furthermore, Figs. 4 to 6 show details of the main parts of the window 3 in this embodiment, and Figs. 7 and 8 show details of the sash spacer 30.

[0024] [1. About window sashes] As shown in Figures 1 to 6, the window sash 10 comprises a window screen 11 into which window glass G is fitted and which opens or closes the opening 2, and a sash frame 12 which holds the window screen 11 in a state in which it can be opened and closed.

[0025] The window screen 11 has a frame 11a into which the window glass G is fitted and which holds the window glass G, and a handle 11b for operating the window screen 11.

[0026] The frame 11a is configured by assembling four resin frame members 111, 112, 113, and 114 manufactured by extrusion molding into a rectangular frame shape, and holds a plurality of window panes G formed into a rectangular shape. Furthermore, the frame members 111 to 114 that make up the frame 11a include a lower frame member 111, an upper frame member 112, a left frame member 113, and a right frame member 114, and these frame members 111 to 114 all have the same cross-sectional shape.

[0027] The handle 11b can rotate around an axis that is linked to a locking mechanism 11c provided at one end of the frame 11a. In other words, by rotating the handle 11b around the axis, the locking mechanism 11c can lock and unlock the window screen 11.

[0028] The sash frame 12 is constructed by assembling four resin frame members 121, 111, 123, 124 manufactured by extrusion molding into a rectangular frame shape, and the window screen 11 is placed inside it. That is, when the window screen 11 is fitted inside the sash frame 12, the opening 2 is closed, and when the window screen 11 is slid out to the outside, the opening 2 is opened.

[0029] Furthermore, the frame materials 121 to 124 that make up the sash frame 12 include a lower frame material 121, an upper frame material 122, a left frame material 123, and a right frame material 124, and these frame materials 121 to 124 all have the same cross-sectional shape.

[0030] In addition, the sash frame 12 (each frame material 121-124) has a first fixing piece 12a which is fixed in contact with the edge of the opening 2, i.e., the end face of the wall 1 in which the opening 2 is formed, on the opening 2 side, and a second fixing piece 12b which is fixed in contact with the outdoor side face of the wall 1 in which the opening 2 is formed. The first fixing piece 12a is formed protruding from the wall 1 side end of the main body part of the sash frame 12 (for example, in the case of the lower frame material 121, this refers to the lower end) toward the indoor side and along the end face of the opening 2 side of the wall 1. The second fixing piece 12b is formed so as to protrude vertically downward along the outer surface of the wall 1 from the end of the main body portion of the sash frame 12 on the wall 1 side. The first fixing piece 12a and the second fixing piece 12b are fixed to the wall 1 with screws.

[0031] Here, the wall 1 of this embodiment is made of architectural wood panels. That is, the building itself is constructed by the so-called panel construction method, but this is not limited to this, and it may be constructed by the conventional frame construction method or wall construction method. However, regardless of the construction method used to construct the building, it is assumed that the edge of the opening 2 is provided with a base material that serves as a fixing base for the screws that fix the sash frame 12. Architectural wood panels are made by assembling vertical and horizontal frame materials Fm into a rectangular shape, with auxiliary crosspieces assembled vertically and horizontally inside the rectangular frame to form a frame body, and then pasting a surface material B such as plywood onto one or both sides of this frame body, resulting in a hollow structure. Furthermore, the hollow part is filled with heat insulating material. 4 to 6, the first fixing piece 12a and the second fixing piece 12b of the sash frame are fixed to the frame material Fm, the face material B, and the adjusting material 1a fixed to the frame material Fm of the architectural wood panel that constitutes the wall 1. In other words, the frame material Fm, the face material B, and the frame material Fm function as base materials for the screws that fix the sash frame 12.

[0032] Moreover, the sash frame 12 (each of the frame members 121-124) further has a rising portion 12c formed in a portion of the main body of the sash frame 12 that is located closest to the indoor side. This rising portion 12c protrudes from the end face of the wall 1 on the side of the opening 2 toward the center of the opening 2, and functions as a door stop with which the indoor side of the frame 11a of the window screen 11 comes into contact when the opening 2 is closed by the window screen 11. A waterproof packing is provided on the outdoor side of the tip of this rising portion 12c.

[0033] Furthermore, sash frame 12 (each of frame materials 121-124) further has drip edge 12d formed in a portion of the main body of sash frame 12 that is located closest to the exterior. Drip edge 12d is formed to protrude in the direction opposite to first fixing piece 12a, and its protruding tip is located outward from the outer surface of exterior material 4 provided on the outdoor side of wall 1.

[0034] The exterior material 4 is attached to the outdoor side of the wall 1 to cover the outdoor side of the wall 1. To explain in more detail, a moisture-permeable waterproof sheet is attached to the outdoor side of the wall 1, and furring strips 4a are fixed on top of the sheet, and the exterior material 4 is attached and fixed to the furring strips 4a. A joint is formed between the upper end surface of the exterior material 4 and the lower surface of the main body portion of the sash frame 12, with a backup material 4b provided at the bottom of the joint and a sealing material 4c filled in the joint. The drip edge 12d in the sash frame 12 protrudes outward from the outer surface of the exterior material 4, and can provide weatherproofing for the portion of the wall 1 (the exterior material 4 and the above-mentioned joints) located below the drip edge 12d.

[0035] [2. About window frames] As shown in Figs. 4 to 6, the window frame 20 is fixed to the end face of the wall 1 on the opening 2 side, and covers the indoor side of the end face of the wall 1 on the opening 2 side. Such a window frame 20 is constructed by assembling four factory-produced wooden window frame members 201, 202, and 203 into a rectangular frame shape.

[0036] In addition, the window frame materials 201-203 that make up the window frame 20 include a lower window frame material 201, an upper window frame material 202, a left window frame material 203, and a right window frame material (not shown), and each of these window frame materials 201-203 has the same cross-sectional shape. Of the four window frame materials 201-203, the lower window frame material 201 is also called a window sill, and may function as a storage space for placing items. Therefore, the lower window frame material 201 may be formed to protrude further inside the room than the other window frame materials. In that case, the lower window frame material 201 may have a cross-sectional shape different from the other window frame materials 202, 203.

[0037] Further, the window frame 20 (each of the window frame materials 201-203) has a recess 20a formed in the sash frame 12 side end of the main body portion of the window frame 20 at the wall 1 side end, in which the first fixed piece 12a of the sash frame 12 is accommodated. That is, the recess 20a is formed by cutting out an L-shaped corner of the main body portion of the window frame 20 that is closest to the first fixed piece 12a.

[0038] The window frame 20 (each of the window frame materials 201-203) further has a protruding edge 20b that protrudes toward the inside of the room from the indoor side end of the central end of the opening 2 in the main body of the window frame 20. This protruding edge 20b also functions as a portion against which the end of the interior material 5 (plaster board) attached to the indoor side of the wall 1 is abutted. The interior material 5 is attached to the indoor side of the wall 1, but its end on the opening 2 side also contacts the indoor side of the main body of the window frame 20. In other words, the indoor side of the wall 1 and the indoor side of the main body of the window frame 20 are arranged so as to be flush with each other, and the interior material 5 is provided straddling between the wall 1 and the window frame 20. Also, the end of the interior material 5 on the opening 2 side is arranged so as to fit snugly into the recessed corner formed by the indoor side of the main body of the window frame 20 and the back surface of the protruding edge 20b.

[0039] The thickness dimension of the main body of the window frame 20 is set to about half the rise dimension of the rising portion 12c of the sash frame 12. In other words, when the window frame 20 is attached and fixed to the end face of the opening 2 side of the wall 1, the length to the central side of the opening 2 is about half the rise portion 12c of the sash frame 12, so that if the sash spacer 30 is not attached, the indoor side of the rise portion 12c will be exposed to the indoor side. In other words, because the window frame 20 is formed in such a thin state, the design gives a sharp impression to people who see the window frame 20.

[0040] [3. About sash spacers] The sash spacer 30 is a resin molded product manufactured by extrusion molding, and as shown in Figures 1 to 8, it is fixed to the indoor side of the rising portion 12c of the sash frame 12 and positioned between the sash frame 12 and the window frame 20, thereby filling the gap S formed between the sash frame 12 and the window frame 20. More specifically, the sash spacers 30 are fixed to the rising portions 12c of the frame members 121-124 of the sash frame 12. Therefore, in this embodiment, four sash spacers 30 are used. And, since each sash spacer 30 is fixed to the indoor side of the rising portions 12c of each of the frame members 121-124 arranged in a rectangular frame shape, the four sash spacers 30 are also arranged in a rectangular frame shape.

[0041] Here, the window frame 20 of this embodiment is an exclusive product of the house manufacturer, and is an in-house product that conforms to a unique design. In contrast, the window sash 10 of this embodiment is a so-called general route product, which is manufactured in accordance with unified standards and is generally distributed. Therefore, a gap S may be formed between the sash frame 12 and the window frame 20 in the window sash 10, and the sash spacer 30 is provided to fill such a gap S. In other words, when a dedicated product of the house manufacturer is used as the window sash, the sash spacer 30 is basically not used. In addition, if a window sash 10, which is a general route product, is used and not only no gap S is formed between the sash frame 12 and the window frame 20, but rather the gap between the sash frame 12 and the window frame 20 becomes clogged, the outdoor side of the window frame 20 may be scraped off on-site to adjust the dimensions. The reason why general route products are adopted is often to reduce the cost of the entire building and shorten the construction period. In addition, when the wall thickness is increased to improve insulation, etc., a gap S may be formed between the sash frame 12 and the window frame 20. In such a case, regardless of whether the window sash 10 is a general route product or a dedicated product, a gap S will be formed, so a sash spacer 30 is used as appropriate.

[0042] The shape of such a sash spacer 30 will be explained using Figures 4, 7 and 8 as examples. The sash spacer 30 comprises a main body portion 31 which includes a portion which is sandwiched between the sash frame 12 and the window frame 20 and a portion which is exposed to the inside of the room, and a fixing portion 32 which is fixed to the raised portion 12c of the sash frame 12.

[0043] The main body 31 has a front surface 31a and an upper end surface 31b that are exposed indoors. When the front surface 31a of the main body 31 is disposed between the sash frame 12 and the window frame 20, the entire surface is not exposed, but is partially shielded by the window frame 20. The upper end surface 31b of the main body 31 is flush (or approximately flush) with the upper end surface of the rising portion 12c, so that no significant unevenness is formed between the rising portion 12c and the sash spacer 30.

[0044] The main body 31 further includes a bulging portion 31c formed on the rear side of the main body 31, bulging out toward the outdoor side, and adjacent to the indoor side of the rising portion 12c. For example, double-sided tape 31d is attached to this bulging portion 31c, so that the sash spacer 30 can be attached to the indoor side surface of the rising portion 12c. An adhesive may be used instead of the double-sided tape 31d.

[0045] The sash spacer 30 of this embodiment corresponds to the window sash 10 shown in Figures 4 to 6, and when another window sash is used, the size of the gap S formed between the window frame 20 may be different. To accommodate such cases, the sash spacer 30 may be prepared with a different thickness dimension of the main body 31. In other words, the sash spacer 30 is available in a number of variations with different thickness dimensions of the main body 31 according to the size of the window sash used, and can appropriately accommodate even when the size of the gap S formed between the sash frame 12 and the window frame 20 is different.

[0046] The fixing portion 32 extends downward from a portion of the lower end of the main body portion 31 on the rear side. The fixing portion 32 has a plurality of screw holes 32a formed at intervals in the length direction. The front surface of the fixing part 32 is located on the rear side of the front surface 31a of the main body part 31. In other words, there is a step between the main body part 31 and the fixing part 32. This step is for forming a gap S between the front surface of the fixing part 32 and the window frame 20, and the head of the screw inserted into the screw hole 32a is accommodated in this gap S.

[0047] A support leg 32b that protrudes to the outdoor side by approximately the same amount as the bulging dimension of the bulging portion 31c is integrally formed at the lower end of the fixing portion 32. The support leg 32b contacts the indoor side surface of the rising portion 12c and supports the sash spacer 30 together with the bulging portion 31c. Furthermore, a so-called hollow structure is formed between the support leg portion 32b and the bulge portion 31c, and this structure has a slight elasticity. If the support leg 32b is not provided and the entire back surface of the sash spacer 30 is flat and inelastic, when the sash spacer 30 is screwed to the rising portion 12c by inserting a screw through the screw hole 32a, the force of the screw pushing the screw toward the rising portion 12c may cause the upper end of the main body 31 to deform slightly in a direction away from the rising portion 12c. In contrast, the sash spacer 30 of this embodiment has a hollow structure between the support leg 32b and the bulge 31c, which is in a slightly elastic state, so that it can absorb the force of the screw pushing the screw toward the rising portion 12c. As a result, the sash spacer 30 of this embodiment can prevent the upper end of the main body 31 from moving away from the rising portion 12c even when the sash spacer 30 is screwed to the rising portion 12c. Moreover, most of the area (hollow area) in which the hollow structure is formed in the sash spacer 30 is sandwiched between the sash frame 12 and the window frame 20. Therefore, the upper end of the main body 31 is unlikely to separate from the rising portion 12c.

[0048] The sash spacer 30 may further include an auxiliary leg 33 located between the bulge 31c and the support leg 32b and set to the same protruding dimension as the bulge 31c and the support leg 32b. When such an auxiliary leg 33 is provided, a portion that contacts the rising portion 12c can be added while maintaining the hollow structure formed between the support leg 32b and the bulge 31c. Therefore, the sash spacer 30 can be attached to the sash frame 12 in a more stable state while maintaining the effect of preventing the upper end of the main body 31 from moving away from the rising portion 12c due to the hollow structure as described above.

[0049] The sash spacer 30 configured as above is fixed to the rising portions 12c of the frame members 121 to 124 of the sash frame 12 by screws, as shown in Figs. At this time, each sash spacer 30 is in contact with the first fixed piece 12a of each frame material 121-124 in the sash frame 12, but this is not limited to this, and taking into account the cutting tolerance of the sash spacer 30, it may be positioned in a state spaced apart from the first fixed piece 12a of each frame material 121-124 in the sash frame 12.

[0050] Furthermore, each sash spacer 30 is attached in advance to the rising portion 12c of each of the frame members 121 to 124 at the factory, which reduces the amount of on-site installation work. The window sash 10 itself may be attached to the wall 1 (architectural wood panel) in advance at a factory.

[0051] Moreover, the screw fastening positions of each sash spacer 30 are covered by the window frame 20 (201 to 203). The window frame 20 may be attached later on-site, or may be attached in advance at the factory.

[0052] 6 is a cross-sectional view showing the details of the left side portion of the window 3. An adjustment material 1a, which is a square timber that forms the edge of the opening 2, is attached to the end face of the wall 1 on the side of the opening 2. The left frame material 123 of the sash frame 12 is attached to this adjustment material 1a. A batten member 6 is provided on the outdoor side of the adjustment material 1a, and a sealing material 4c is filled between the side end of the exterior material 4 and the batten member 6. Although the left side portion of the window 3 has been described in detail with reference to FIG. 6, the right side portion of the window 3 is also configured symmetrically.

[0053] Furthermore, by using a window sash 10 made from a general route product, it may be necessary to adjust dimensions, for example, in the installation position of the sash frame 12. Therefore, as shown in Figures 5 and 6, for example, when installing the sash frame 12, a thin plate 7 may be interposed between the wall 1 or the adjustment material 1a to appropriately adjust the dimensions.

[0054] [4. About the effects] According to this embodiment, the following excellent effects are obtained. That is, the sash frame 12 that constitutes the window sash 10 together with the window screen 11 is positioned away from the window frame 20 on the outdoor side, forming a gap S between the sash frame 12 and the window frame 20, and a sash spacer 30 is attached to the indoor side of the sash frame 12 to fill the gap S, so that even if a gap S is formed between the sash frame 12 and the window frame 20, for example, when a window sash 10 made from a general route is used, the gap S can be filled by the sash spacer 30. This eliminates the need to manufacture a new window frame to prevent the gap S from being formed between the sash frame 12, which ultimately reduces the cost of the entire building and shortens the construction period.

[0055] Furthermore, a portion of the main body 31 of the sash spacer 30 is exposed to the indoor side while another portion of the main body 31 and the fixing portion 32 are shielded by the window frame 20, so that the gap S between the sash frame 12 and the window frame 20 is filled while the fixing portion 32 is reliably shielded to improve the appearance. Furthermore, since the sash spacer 30 has a main body 31 including a portion that is sandwiched between the sash frame 12 and the window frame 20, a portion of the sash spacer 30 is sandwiched between the sash frame 12 and the window frame 20, thereby improving the installation condition of the sash spacer 30.

[0056] In addition, since a recess (hollow structure) is formed on the surface of the sash spacer 30 facing the sash frame 12, the area of ​​the sash spacer 30 where the recess is formed has a slight elasticity. The part of the main body 31 that is sandwiched between the sash frame 12 and the window frame 20 and the fixing part 32 overlap with the area where the recess is formed, and the fixing part 32 has a screw hole 32a through which a screw is inserted, so that the force of the screw being pushed into the sash frame 12 side can be absorbed. In addition, since the main body 31 includes a part that is sandwiched between the sash frame 12 and the window frame 20, the main body 31 is pressed against the sash frame 12 side by the window frame 20. This makes it possible to prevent the upper end of the main body 31 from moving away from the rising part 12c when the sash spacer 30 is fixed to the sash frame 12 by a screw.

[0057] In addition, since the end face of the sash spacer 30 located on the central side of the opening 2 and the end face of the rising portion 12c located on the central side of the opening 2 are flush with each other, it is possible to improve the unity between the rising portion 12c and the sash spacer 30. This allows the gap S formed between the sash frame 12 and the window frame 20 to be filled with the sash spacer 30 in an attractive manner.

[0058] Furthermore, since the fixing piece 12a of the sash frame 12 is housed in the recess 20a of the window frame 20, impact between the sash frame 12 and the window frame 20 can be prevented. Furthermore, since the bottom of the gap S formed between the sash frame 12 and the window frame 20 is the fixed piece 12a, the sash spacer 30 can be positioned based on the fixed piece 12a, making it easier to install the sash spacer 30.

[0059] In recent years, there has been a demand for the realization of a decarbonized society through the promotion of carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and for the achievement of the SDGs (Sustainable Development Goals), and the construction industry is also working to build buildings out of wood, which produces less carbon dioxide emissions. The fitting structure of the window 3 in this embodiment can contribute to the realization of a decarbonized society through the promotion of carbon neutrality, and the achievement of SDGs goals 7, 12, and 13, etc., because the building is constructed by a panel construction method using architectural wood panels and the window frame 20 is made of wood.

[0060] [Modifications] The embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be modified as appropriate without departing from the spirit of the present invention. Modifications are described below. The following modifications may be combined as far as possible. In each of the following modifications, elements common to the above-described embodiments are denoted by the same reference numerals, and descriptions thereof are omitted or simplified.

[0061] Because the sash spacer 30 is provided along the indoor side surface of the rising portion 12c of the sash frame 12, it is ideal to arrange it so that it fits snugly against the rectangular sash frame 12. However, because the sash spacer 30 is extrusion molded and used after being cut with a cutting tool or the like having a thick blade, there is inevitably a cutting tolerance, making it extremely difficult to arrange it so that it fits snugly against the sash frame 12.

[0062] In contrast, in this embodiment, as shown in Figures 1 to 3, a method is adopted in which a horizontal sash spacer 30 is disposed between the lower ends and upper ends of two vertical sash spacers 30. In other words, four sash spacers 30 are disposed so as to be in a so-called vertically overlapping state. Furthermore, the two horizontal sash spacers 30 are cut to have a length slightly shorter than the design dimension. In addition, the two vertical sash spacers 30 are cut to a length that is as close as possible to the design dimension, within the range that fits between the first fixed piece 12a of the lower frame material 121 in the sash frame 12 and the first fixed piece 12a of the upper frame material 122.

[0063] More specifically, first, as shown in Figs. 1 and 3, the right-side vertical sash spacer 30 (third sash spacer 30) is screwed to the right-side frame material 124 of the sash frame 12. In addition, in this embodiment, when the right vertical sash spacer 30 (third sash spacer 30) is screwed to the right frame material 124, it is not spaced from the first fixing piece 12a, but this is not limited to this. For example, the right vertical sash spacer 30 (third sash spacer 30) may be disposed in a state spaced 1 mm from the first fixing piece 12a of the right frame material 124 in the sash frame 12 and screwed at that position. In this way, the right vertical sash spacer 30 protrudes 1 mm from the rising portion 12c of the right frame material 124.

[0064] Next, the lower lateral sash spacer 30 (first sash spacer 30), which is slightly shorter than the design dimension, is placed in a state of tight contact with the first fixing piece 12a of the lower frame material 121 of the sash frame 12, and screwed in place. This makes the upper end surface 31b of the lower sash spacer 30 flush with the upper end surface of the rising portion 12c of the lower frame material 121. At this time, the lower sash spacer 30 may be moved toward the vertical sash spacer 30 on the right side so that these sash spacers 30 are in contact with each other.

[0065] Next, the upper horizontal sash spacer 30 (second sash spacer 30), which is slightly shorter than the design dimension, is placed in a state of tight contact with the first fixing piece 12a of the upper frame material 122 in the sash frame 12, and screwed in place. This makes the lower end surface 31b of the upper sash spacer 30 flush with the lower end surface of the rising portion 12c of the upper frame material 122. At this time, the upper sash spacer 30 may be moved toward the vertical sash spacer 30 on the right side so that these sash spacers 30 are in contact with each other.

[0066] Next, the left vertical sash spacer 30 (fourth sash spacer 30) is placed with a gap of 1 mm or more from the first fixing piece 12a of the left frame material 123 of the sash frame 12, and is screwed in place. As a result, the left vertical sash spacer 30 protrudes 1 mm or more from the rising portion 12c of the left frame material 123.

[0067] When the sash spacers 30 are installed in the above-described manner, the left sash spacer 30 installed last can absorb the cutting tolerances of the right vertical sash spacer 30 and the upper and lower horizontal sash spacers 30.

[0068] Furthermore, if the four sash spacers 30 were fitted with a horizontal lead, for example, when the sash spacers 30 as a whole sag due to aging, there is a possibility that a gap S would occur between the upper sash spacer 30 and the two vertical sash spacers 30. In contrast, by fitting with a vertical lead as described above, even if the sash spacers 30 as a whole sag due to aging, for example, a gap S is unlikely to occur between the sash spacers 30, and a good external design can be easily maintained even if aging occurs.
