DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, the same reference numerals in different drawings denote parts with the same functions, and duplicated descriptions in each drawing will be omitted as appropriate.

[0011] [Example 1] (opening device) Example 1 is mainly an example of the first aspect (claim 1). Example 1 will be explained assuming that "one of the mullions 2 or the interlock 9" in the first aspect is the mullion 2. Example 1 is an example in which a vertical sliding window 1 is used as the opening device. Fig. 1 is an internal view of the vertical sliding window 1 (opening device) before an attachment member 6 is attached. The vertical sliding window 1 (opening device) of Example 1 is equipped with an adjuster 16. One end of the extendable adjuster 16 is attached to a sash frame side support member 162, and the other end is attached to a shoji side support member 161, thereby supporting the shoji 14 so that it can slide freely relative to the sash frame 11. In addition, the shoji 14 on the mullion 2 side has a handle 18 for opening and closing the vertical sliding window 1 (opening device).

[0012] There are four sash frames 11 in Figure 1, and each sash frame 11 is separated by a mullion 2 and a lattice 9. The mullion 2 is attached between the interior sides 112 of the adjacent left and right sash frames, and the interior sides of the mullions 2 and the interior sides 112 of the sash frames are almost flush with each other. The sash frame 11 in FIG. 1 is attached to a wall 17. The opening devices 1 on the upper right and upper left, separated by a mullion 2, are both vertical sliding windows 1. The two sash frames 11 separated by a mullion 2 below the transom 9 are fixed windows.

[0013] (Attachment) Figure 2 is an interior view of Example 1 after an accordion screen door 61 (attachment member 6) has been attached to the mullion 2 of the vertical sliding window 1 (opening device) in Figure 1. For the sake of explanation, Figure 2 does not show the screen portion of the accordion screen door 61, which is the attachment member 6, and only shows the screen door frame 63.

[0014] The base material 3 will be described later, but it is covered with a cover material 4 and attached in a position that cannot be seen in Figure 2. The base material 3 is attached across the sash frame interior side surfaces 112 of the left and right sash frames 11 and the interior side of the mullion 2. The base material 3 is covered with the cover material 4 except for the opposing surface portion 31 that faces the mullion interior side surface 22, and only the cover material 4 is visible from the interior side. FIG. 3 is a perspective view of the frame A portion of FIG. 2 according to the first embodiment. The upper and lower screen frames 63 of the accordion screen 61 shown in Figure 2 are attached to the visible surface 41 of the cover material assembly of the base material 3 (not visible in Figure 2) and cover material 4 shown in Figure 3. The assembly of the base material 3 and cover material 4 functions as a so-called covering member. The upper and lower screen door frames 63 have rails (not shown) inside so that the screen door can be opened and closed in the left and right directions. The screen door frames 63 attached to the wall 17 side in Figure 2 have the function of fixing the front of the door in place when the accordion screen door 61 (not shown) is closed to cover the opening, keeping the door closed and preventing insects from entering. The attachment member 6 is not limited to the accordion screen door 61, but may be a light, a roller curtain, a blind, or the like. In addition, in Example 1, the screen frame 63, which is the attachment member 6, is attached to the visible surface portion 41 of the cover material, but depending on the type of attachment member 6 (e.g., lighting fixture, etc.), it is also possible to attach it to the visible surface portion 45 of the cover material on the indoor side.

[0015] (mullion and sash frame) FIG. 3 is a perspective view of the frame A portion of FIG. 2 according to the first embodiment. The mullions 2 are provided between adjacent sash frames 11 on the left and right. The exterior side of the upright 2 is arranged across the exterior side surfaces 111 of the sash frames 11 on both sides of the upright 2. In addition, the indoor side of the mullion 2 is arranged between the indoor side surfaces 112 of the sash frames 11 on both sides of the mullion 2. The upper screen door frame 63 shown in FIG. 3 can be seen attached to the cover material visible surface portion 41 at a distance from the sash frame 11.

[0016] Figure 4 is a cross-sectional view of Example 1 between B and B shown in Figure 2. The screen door frame 63 and the opening device 1 (vertical sliding window) are spaced far enough apart, and it can be seen that the handle 18 is positioned so as not to interfere with opening and closing the accordion screen door 61. One end of the screen door frame 63 is attached to the visible surface portion 41 of the cover material, while the other end is attached to the wall 17. Incidentally, a series of windows, such as three or more sash frames 11, have an opening device 1 sandwiched between two mullions 2. When applying Example 1 here, it goes without saying that the screen door frame 63 to be installed is an assembly of a base material 3 and a cover material 4, which is mounted on the mullions 2 on the left and right of the sash frame 11 (including the sash frames 11 on both sides of each mullion 2) as a base.

[0017] Figure 5 is an enlarged view of Example 1 of frame B shown in Figure 4. Figure 5 is an explanatory diagram of the mounting structure of the assembly of base material 3 and cover material 4 to mullions 2 and sash frame 11, as well as the internal structure of the assembly. For ease of explanation, the attachment member 6 (accordion screen door 61) is not shown.

[0018] (Base material structure and mounting structure) The base material 3 shown in Figure 5 is composed of an opposing surface portion 31 that faces the upright room side portion 22 and an engaging piece portion 32 that engages with the cover material 4 extending from both the left and right ends of the opposing surface portion 31 toward the room side. The opposing surface portion 31 facing the upright 2 extends not only to the upright 2 but also to the area where the sash frame 11 is located (the sash frame interior side surface 112).

[0019] (opposing surface and spacer) The opposing surface portion 31 of the base material 3 shown in Figure 5 is not in direct contact with the mullion interior side surface portion 22 or the sash frame interior side surface 112. A space 74 is created between the mullion 2 (mullion interior side surface portion 22) and the opposing surface portion 31 of the base material 3, preventing heat from being transferred from the mullion 2 to the base material 3. A spacer 5 made of a thermally insulating material is disposed in the space 74, occupying most of the space 74. The spacer 5 made of a thermally insulating material blocks the space 74 and further suppresses heat transfer between the mullion 2 and the base material 3. The spacer 5 is attached to the base material 3. The left and right ends of the opposing surface portion 31 of the base material 3 on the side of the upright 2 have spacer holding grooves 34, and the spacer protrusions 51 fit into these grooves, so that the spacer 5 is integrated with the base material 3. Furthermore, the left and right ends of the spacer 5 form gap forming portions 52, which are sandwiched between the sash frame indoor side surface 112 and the opposing surface portion 31. The sash frame indoor side surface 112 and the opposing surface portion 31 are separated by the gap forming portions 52 of the spacer 5, and a gap 73 is formed.

[0020] The base material 3 is fastened to the mullion chamber interior side surface portion 22 by fasteners 54. The opposing surface portion 31 of the base material 3 is attached to the mullion 2 by fasteners 54 arranged via resin washers 53, with a spacer 5 made of thermal insulating material sandwiched between the base material 3 and the mullion 2 (mullion chamber interior side surface portion 22). The resin washer 53 blocks heat transmitted from the mullion 2 through the fastener 54 and prevents it from being transmitted to the base material 3.

[0021] (Soft screening material) As described above, the spacer 5 is arranged to intentionally create a gap 73 between the base material 3 and the sash frame 11 in order to prevent direct contact between the base material 3 and the sash frame 11 shown in Figure 5. Furthermore, the thermal insulating member 7 is provided at the left and right ends of the opposing surface portion 31 of the base material 3. The thermal insulating member 7 has soft covering material 71 (fins) at its outer end to hide the gap 73. The soft covering material 71 (fins) can block heat from entering or leaving the gap 73, but the soft covering material 71 (fins) is part of the thermal insulating member 7 and is made of a thermal insulating material, so it contributes to thermal insulation (thermal insulation). As described above, the soft privacy material 71 (fin piece) of Example 1 hides the small gap 73 that occurs between the sash frame interior side surface 112 and the opposing surface portion 31 of the base material 3. The soft privacy material 71 (fin piece) not only contributes to heat insulation, but also hides the gap 73 that occurs between the base material 3 and the sash frame 11, thereby contributing to improved design. The soft screening material 71 can be formed in a shape and material that emphasizes heat insulation, or in a shape and material that emphasizes design. Since the main purpose of the soft screening material 71 is to provide privacy, the shape is not limited to fin pieces.

[0022] (Fitting of cover and base materials) The materials of the base material 3 and the cover material 4 shown in Fig. 5 are not particularly limited. The base material 3 may be an aluminum molded material and the cover material 4 may be made of resin, or both may be made of resin. A pair of fitting pieces 32 on the left and right sides of the opposing surface portion 31 of the base material 3 are intended to fit with the cover material 4. The fitting pieces 32 of the base material 3 have fitting protrusions 321 that protrude from the outer periphery thereof. After the base material 3 is attached to the mullions 2, the cover material 4 is attached. The cover material 4 has fitting protrusions 43 on its inner surface that fit into the fitting protrusions 321 of the base material 3. The cover material 4 is slightly larger than the base material 3, and the side facing the base material 3 is open so that the base material 3 can be swallowed up by the inner surface of the cover material 4 when attached. The cover material 4 covers the base material 3 and is attached to the base material 3. The worker pushes the cover material 4 toward the attached base material 3. By this operation, the worker can fit the fitting convex portion 321 of the base material 3 into the fitting protrusion 43 of the cover material 4, and attach the cover material 4 to the base material 3.

[0023] The cover material 4 shown in FIG. 5 has a partition wall 46 inside to provide additional strength. Furthermore, there is a possibility that a small amount of heat flowing in and out through the fasteners 54 may be transmitted into the hollow space separated by the partition wall 46 between the base material 3 and the cover material 4. However, the hollow space is an enclosed space, and is configured to prevent heat from flowing in and out of the hollow space into the room. In this way, Example 1 is designed to thoroughly block heat.

[0024] (Fixing the cover and base materials) As described above, the cover material 4 and the base material 3 of Example 1 can be elastically fitted together and fixed simply by fitting the fitting protrusion 43 of the cover material 4 into the fitting convex portion 321 of the base material 3 shown in Figure 5, so there is no need to fasten them with fasteners 54, resulting in an aesthetically pleasing appearance. In addition, when the attachment member 6 attached to the cover material 4 is heavy, the fitting piece portion 32 of the base material 3 and the projecting surface portion 41 of the cover material may be fastened together.

[0025] (Application to Mume) In Example 1, the "one of the mullions 2 or the lattice 9" in the first embodiment described above is the mullion 2. The mullion 2 in Example 1 is too narrow to mount an assembly of the base material 3 and the cover material 4, and the assembly of the base material 3 and the cover material 4 is mounted across the sash frames 11 on both sides of the mullion. A modified example of the first embodiment is an example in which "one of the mullions 2 or the lattice 9" is the lattice 9. In the modification of the first embodiment, a narrow interlining 9 is an object to which the assembly of the base material 3 and the cover material 4 is attached. For example, if the attachment member 6 is a roller curtain that unfolds vertically, an assembly of the base material 3 and the cover material 4 is attached to the transom 9. At this time, although not shown in the figure, the assembly of the base material 3 and the cover material 4 is attached across the sash frames 11 on both sides (top and bottom) of the narrow transom 9. Other points are the same as in Example 1.

[0026] (Summary and effects of Example 1) As shown in FIG. 5, the first embodiment includes a base material 3 attached to a mullion 2 or a crosspiece 9, and a cover material 4 attached to the base material 3. The base material 3 is placed across the sash frame 11 attached to the mullion 2 or the lattice 9. A spacer 5 made of a thermally insulating material is attached to the base material 3, filling most of the space 74 created between the mullion 2 and the base material 3. Furthermore, the spacer 5 is sandwiched between the sash frame 11 and the base material 3, creating a gap 73 between the sash frame 11 and the base material 3, preventing heat from being transferred from the sash frame 11 to the base material 3. The base material 3 is fixed to the mullion 2 with a fastener 54, sandwiching the spacer 5 between them. A resin washer 53 is attached to the fastener 54 in Example 1, providing thorough insulation. The gap 73 that occurs between the base material 3 and the sash frame 11 (the sash frame interior side surface 112) is hidden by a soft concealing material 71 provided at the end of the thermal insulation member 7, contributing to improved design and thermal insulation.

[0027] In Example 1, the assembly of the base material 3 and the cover material 4 plays the role of a cover member, contributing to the attachment of the attachment member 6. In addition, the assembly of the base material 3 and the cover material 4 can be performed simply by fitting the fitting convex portion 321 and the fitting projection 43 together, which provides good workability. The cover material 4 of Example 1 hides the base material 3 and the mounting surface, and the appearance looks like a single frame material, which is excellent in design.

[0028] [Example 2] (Summary of Example 2) Example 2 is an example mainly relating to the second aspect (claim 2). The assembly of the base material 3 and the cover material 4 in Example 1 was attached to a narrow mullion 2. Therefore, the assembly of the base material 3 and the cover material 4 in Example 1 was attached so as to extend beyond the sash frames 11 on the left and right sides of the mullion 2. The width of the mullions 2 and mullions 9 varies depending on the opening device 1, and there are also mullions 2 and mullions 9 with wide widths. The width of the crossbeam 9 shown in FIG. 1 is wider than the mullion 2, and in Example 2, an assembly of the base material 3 and the cover material 4 is attached to the wider crossbeam 9 or mullion 2. Example 2 will be described assuming that "one of the mullions 2 or the rafters 9" in the second embodiment described above is the rafters 9.

[0029] FIG. 6 is an explanatory diagram of a second embodiment in which an assembly of a base material 3 and a cover material 4 is attached to a lintel 9. In FIG. The transom 9 in FIG. 6 is wide as shown in the drawing, and the assembly of the base material 3 and the cover material 4 can be attached without spanning the sash frames 11 adjacent above and below. The structure of the assembly of the base material 3 and the cover material 4 is the same as that of the first embodiment, and therefore will not be described here.

[0030] The transom 9 of Example 2 is wide, making it possible to attach the assembly of the base material 3 and the cover material 4 to the transom interior facing surface 91. The transom interior facing surface 91 of Example 2 is flat, making it suitable for attaching the assembly of the base material 3 and the cover material 4. Because the transom interior facing surface 91 is flat, the spacer 5 can be attached in close contact with the transom interior facing surface 91. The fastener 54 is attached to the opposing surface 31 of the base material 3 via a resin washer 53, passes through the spacer 5, and is fastened to the transom interior facing surface 91. The opposing surface portion 31 of the base material 3 has spacer holding grooves 34 at the upper and lower ends on the transverse side 9 side, and the spacer 5 is integrated with the base material 3 by fitting the spacer protrusions 51 into the grooves 34 . The upper and lower ends of the spacer 5 form gap forming portions 52. The gap forming portions 52 are sandwiched between the blind interior facing surface portion 91 and the opposing surface portion 31, and a gap 73 is formed between the blind interior facing surface portion 91 and the outdoor end of the cover material 4 at a position adjacent to the spacer 5. The blind members 71 (fin pieces) of the thermal insulating member 7 provided above and below the opposing surface portion 31 hide this gap 73.

[0031] As in the first embodiment, the cover material 4 has a partition wall 46 inside to provide additional strength. Furthermore, there is a possibility that a small amount of heat flowing in and out through the fasteners 54 may be transmitted into the hollow space separated by the partition wall 46 between the base material 3 and the cover material 4. However, the hollow space is an enclosed space, and is configured to prevent heat from flowing in or out of the hollow space into the room. In this way, Example 2 is designed to thoroughly block heat.

[0032] Note that a modified example of Example 2 of the second aspect also includes an example in which "one of the mullion 2 or the lintel 9" is the mullion 3. The modified example is generally the same except that the above-mentioned explanation of the lintel 9 is changed to the lintel 2, so further explanation will be omitted.

[0033] (Summary of Example 2) Although the second embodiment has been described using the mullion 9 as an example, it can also be applied to a wide mullion 2 as mentioned above. Example 2 comprises a base material 3 attached to the mullions 2 or mullions 9, and a cover material 4 attached to the base material 3. The base material 3 is attached to the mullions 2 or mullions 9 with fasteners 54 arranged via resin washers 53, with a spacer 5 made of thermal insulating material sandwiched between the base material 3 and the mullions 2 or mullions 9. A soft concealing material 71 attached to the mullions 2 or mullions 9 side of the base material 3 hides the gap 73 between the base material 3 and the mullions 2 or mullions 9. The cover material 4 is attached to the base material 3 by covering it. The cover material 4 covers the base material 3 and is attached to the base material 3 to form an assembly, which contributes to the attachment of the attachment member 6, etc.

[0034] (Effects of Example 2) The assembly of the base material 3 and cover material 4 in Example 2 is suitable for wide mullions 2 or mullions 9. A spacer 5 made of a thermally insulating material is attached to the base material 3, and it abuts against the interior side of the mullions 2 or mullions 9 to prevent heat from being transmitted to the base material 3. Furthermore, the spacer 5 is sandwiched between the mullions 2 or mullions 9 and the base material 3, creating a gap 73 between the sash frame 11 and the base material 3, preventing heat from being transmitted from the sash frame 11 to the base material 3. The base material 3 is fixed to the mullions 2 with fasteners 54, sandwiching the spacer 5 between them. The fasteners 54 in Example 1 are fitted with resin washers 53, ensuring thorough insulation. The gap 73 that occurs between the base material 3 and the sash frame 11 (the sash frame interior side surface 112) is hidden by a soft concealing material 71 provided at the end of the thermal insulation member 7, contributing to improved design and thermal insulation.

[0035] In Example 2, the assembly of the base material 3 and the cover material 4 plays the role of a cover member, contributing to the attachment of the attachment member 6. In addition, the assembly of the base material 3 and the cover material 4 can be performed simply by fitting the fitting convex portion 321 and the fitting projection 43 together, which is easy to work with. The cover material 4 of Example 1 hides the mounting surface and the base material 3, and the appearance looks as if it were a single frame material, and is excellent in design.

[0036] [Example 3] (Summary of Example 3) Example 3 is mainly an example of the third aspect (claim 3). Example 3 is an example in which "one of the mullions 2 or the interlock 9" in the third aspect is the mullion 2. Example 1 is a mode in which the spacer is attached to a narrow mullion 2. In Example 1, the gap forming portion 52 of the spacer 5 is sandwiched between the sash frame 11 and the opposing surface portion 31 of the base material 3 to separate the base material 3 from the sash frame 11 and create a gap 73, as shown in Figure 5 . 7 is an embodiment in which the cover material 4 is attached to a narrow mullion 2, similar to the embodiment 1. In the embodiment 3, a thermal insulating member 7 is used to separate the cover material 4 from the sash frame 11 to create a gap 73.

[0037] FIG. 7 is an explanatory diagram of a third embodiment in which an assembly of a base material 3 and a cover material 4 is attached to a mullion 2 and a sash frame 11. The structure of the assembly of the base material 3 and the cover material 4 is the same as that of the first embodiment, and therefore will not be described here.

[0038] (Spacer) The spacer 5 made of the thermal insulating material of Example 3 covers the mullion interior side surface portion 22 and is positioned so as to be in slight contact with the sash frame interior side surface 112. The gap 73 created between the sash frame 11 (sash frame interior side surface 112) and the opposing surface portion 31 of the base material 3 is created solely by the thermal insulating member 7 attached to the opposing surface portion 31.

[0039] (Thermal insulation material) The material constituting the thermal insulating member 7 in FIG. 7 is selected from thermal insulating materials having sufficient strength to form the space 74 without being crushed even when fastened with the fasteners 54 . Since the thermal insulating member 7 and the spacer 5 in the third embodiment have different roles, it is possible to select a thermal insulating material suitable for each role. The thermal insulating member 7 is attached to the opposing surface 31 of the base material 3. The worker can complete the installation of the base material 3 by simply abutting the base material 3, to which the thermal insulating member 7 and spacer 5 have already been attached, against the sash frame 11 and fastening it to the mullion 2 with the fasteners 54.

[0040] (fin piece) In the third embodiment, the heat insulating member 7 itself shown in FIG. Furthermore, the thermal insulating member 7 suitable for filling the gap 73 may further include soft fin pieces on the outer periphery that serve as the blinding material 71. Of course, the soft fin pieces that serve as the blinding material 71 are used together with the thermal insulating member 7, but it is also possible to omit the blinding material 71.

[0041] (Resin washer) The third embodiment is provided with a resin washer 53 as in the first embodiment, and prevents heat entering through the fastener 54 from being transmitted to the base material 3 . Furthermore, there is a possibility that a small amount of heat flowing in and out through the fasteners 54 may be transmitted into the hollow space separated by the partition wall 46 between the base material 3 and the cover material 4. However, the hollow space in Example 3 is an enclosed space, and is configured to prevent heat from flowing in and out of the hollow space into the room. In this way, Example 3 is designed to thoroughly block heat.

[0042] The third aspect is a modified example of the third embodiment, in which "one of the mullion 2 or the lintel 9" is the lintel 9. The modified example is generally the same as the above-mentioned description of the mullion 2 except that it is the lintel 9, so the description will be omitted.

[0043] (Summary of Example 3) Example 3 is particularly suitable for narrow mullions 2 or mullions 9. The third embodiment includes a base material 3 attached to the mullion 2 or the crossbeam 9 and a cover material 4 attached to the base material 3. The base material 3 is arranged across the mullion 2 or the lattice 9 and the sash frame 11, and is attached to the mullion 2 or the lattice 9 by fasteners 54 via resin washers 53. The thermal insulation member 7 attached to the mullion 2 or transom 9 side of the base material 3 abuts against the sash frame 11, forming a space 74 between it and the mullion 2 or transom 9. The cover material 4 covers the base material 3 and is attached to the base material 3 to form an assembly, which contributes to the attachment of the attachment member 6, etc.

[0044] (Effects of Example 3) The effects of the third embodiment are generally the same as those of the first embodiment, so the effects of the third embodiment will be described by focusing on the differences from the first embodiment. The member that forms the space 74 is the thermal insulating member 7, whereas in Example 1 it is the spacer 5, whereas in Example 3 it is the thermal insulating member 7. The spacer 5 in Example 1 forms the space 74 and is made of a thermal insulating material that has the strength to form the space 74 and the gap 73 without being crushed even when fastened with the fastener 54. On the other hand, in Example 3, the spacer 5 is not involved in the formation of the gap 73 or the space 74, and is made of a separate thermal insulating member 7. Therefore, the material of the spacer 5 in Example 3 can be selected from a thermal insulating material that is excellent only from the viewpoint of thermal insulation, and strength is not required.

[0045] [Example 4] (Outline of Example 4) Example 4 is an example mainly relating to the fourth aspect (claim 4). Example 4 is directed to a wide mullion 2 or a wide lattice 9. Example 4 is an example in which "one of the mullion 2 or the lattice 9" in the above-mentioned fourth aspect is the lattice 9. The fourth embodiment will be described with reference to the description of the second embodiment and FIG. 6, which are common to the second embodiment in a broad sense.

[0046] (Spacer) As in the second embodiment, the spacer 5 is attached by fitting the spacer protrusion 51 into the spacer holding groove 34 of the opposing surface portion 31 as shown in FIG. The upper and lower ends of the spacer 5 are gap forming portions 52, and the gap forming portions 52 are sandwiched to form a gap 73. The blind members 71 (fin pieces) of the thermal insulating member 7 provided above and below the opposing surface portion 31 hide this gap 73.

[0047] (Soft screening material) The difference from Examples 1 to 3 is that the washer may be made of either resin or metal. Moreover, Example 4 employs the soft screening material 71 employed in the first aspect (Example 1) and the second aspect (Example 2). A gap 73 formed between the base material 3 and the sash frame 11 (the sash frame interior side surface 112) is closed by a soft screening material 71 provided at the end of the thermal insulation member .

[0048] (Fastened seamlessly with the opposing surface of the base material) The opposing surface 31 of the base material 3 and the blind interior facing surface 91 are fastened together with a fastener 54, sandwiching a spacer 5 therebetween. A resin washer 53 or a metal washer is attached to the fastener 54. As with the other embodiments, there is a possibility that a small amount of heat flowing in and out through the fastener 54 may be transmitted into the hollow space separated by the partition wall 46 between the base material 3 and the cover material 4. However, the hollow space is an enclosed space, and is configured so that heat does not flow in or out of the hollow space into the room. Therefore, the use of a metal washer in Example 4 does not have a significant impact on heat loss.

[0049] (Modification of Example 4) A variation of Example 4 also includes an example in which "one of the mullions 2 or the mullion 9" is the mullion 3. The variation is generally the same except that the above-mentioned explanation of the mullion 9 is changed to the mullion 2, so further explanation will be omitted.

[0050] (Summary of Example 4) Example 4 is an embodiment suitable for a wide mullion 2 or a wide slat 9. The fourth embodiment includes a base member 3 that is attached to the mullion 2 as in Fig. 5 or to the lintel 9 as in Fig. 6. The fourth embodiment also includes a cover member 4 that is attached to the base member 3 as in the other embodiments. The base material 3 is attached to the mullions 2 or the lattice 9 by fasteners 54 with a spacer 5 made of a thermal insulating material sandwiched between the base material 3 and the mullions 2 or the lattice 9. The base material 3 has a soft concealing material 71 attached to the side of the mullion 2 or the lattice 9, and hides a gap 73 formed between the mullion 2 or the lattice 9. The cover material 4 covers the base material 3 and is attached to the base material 3.

[0051] (Effects of Example 4) The fourth embodiment has the same effects as the second embodiment.

[0052] (Summary of effects of all examples) All of the numerous embodiments and variations described in this specification thoroughly prevent heat from entering or escaping the room through the mullions 2 or the latticework 9. Therefore, the assembly of the base material 3 and the cover material 4 is arranged with a space 74 and a gap 73 so as not to come into direct contact with the mullions 2, the lattice 9 and the sash frame 11. The spaces 74 and gaps 73 are filled with spacers 5 made of thermal insulating material and thermal insulating members 7 to provide thermal insulation. Furthermore, a blind 71 is provided in the gaps 73 leading to the interior of the room to improve thermal insulation and design. The fastener 54 connects the base material 3 to the mullion 2 or the lattice 9, and by attaching a resin washer 53, further improvement in thermal insulation can be achieved. Even if a small amount of heat flows in or out of the base material 3 through fasteners 54 or the like, it is enclosed in a closed space surrounded by the base material 3 and the cover material 4 and the partition wall 46 of the cover material 4, and is prevented from flowing out or in to the inside of the room. The assembly of the base material 3 and the cover material 4 serves as a cover member for attaching an attachment member 6 such as an accordion screen door 61.

[0053] Although the embodiments of the present invention have been described in detail above with reference to the drawings, the specific configurations are not limited to these embodiments, and the present invention also includes design changes and the like within the scope of the present invention that do not deviate from the gist of the present invention.

[0054] Furthermore, the above-described embodiments can be combined by utilizing the techniques of each other, as long as there are no particular contradictions or problems in the purpose, configuration, etc. [Explanation of symbols]
