[0061] The cover material 8 comprises an indoor-side cover material main body 81 and a hollow portion 82. The indoor-side cover material main body 81 is formed in the shape of a rectangular plate. The indoor-side cover material main body 81 has a width greater than the width of the mullions 5 in the left-right direction across the mullions 5 in the view direction, and has a length in the longitudinal direction of the indoor-side cover material main body 81 that is the same as the length of the mullions 5 in the longitudinal direction.

[0062] The hollow portion 82 is formed at the center position of the indoor-side cover material main body 81 in the left-right direction across the mullions 5 in the view direction. The interior of the hollow portion 82 is divided into multiple sections along the longitudinal direction of the indoor-side cover material main body 81.

[0063] Next, the covering material 9 and the structure for attaching the covering material 9 to the renovated fitting 1 will be described. As shown in Fig. 3, the covering material 9 comprises an outdoor covering material main body 91, an engaged portion 92, and an adhesive portion 93. The outdoor covering material main body 91 has a width wider than the width of the mullion 5 in the left-right direction across the mullion 5 in the facing direction, and a length in the longitudinal direction of the outdoor covering material main body 91 that is the same as the length of the mullion 5 in the longitudinal direction. The outdoor covering material main body 91 is arranged so as to cover the entire outdoor side X1 of the mullion 5 from the outdoor side X1. A protrusion 913 with a tapping hole 912 formed therein is provided on the outdoor side X2 surface of the outdoor covering material main body 91.

[0064] The engaged portion 92 has a hook shape that extends from the indoor side X2 surface of the outdoor cover material main body 91 toward the indoor side X2 at one end of the outdoor cover material main body 91, bends toward the other end of the outdoor cover material main body 91 (to the right in Figure 3), and then bends back toward the one end of the outdoor cover material main body 91. The hook-shaped portion of the engaged portion 92 engages with and is fixed to an engaging portion 543b that is formed by a portion of the T-shaped cover portion 543 fixed to the vertical attachment frame 44 near the mullion 5. The vertical attachment frame 44 and the T-shaped cover portion 543 form an intermediate member between the existing vertical frame 24 and the new vertical frame 34.

[0065] The adhesive portions 93 have multiple L-shaped portions that extend from the indoor side X2 surface of the outdoor cover material main body 91 toward the indoor side X2 at the other end of the outdoor cover material main body 91 and bend toward the other end (to the right in Fig. 3) of the outdoor cover material main body 91. The outdoor cover material main body 91 is cut, for example, along the cut line shown by the two-dot chain line in Fig. 3, and the portion to the right of the cut line is removed as unnecessary.

[0066] The L-shaped end portion 93a of the adhesive portion 93 remaining on the outer-covering material main body 91, whose width in the facing direction has been adjusted to an appropriate value in this way, on the indoor side X2, faces the part 93a that faces the part of the T-covering portion 553 closer to the mullion 5, and the part 553a of the T-covering portion 553 closer to the mullion 5, are adhered with adhesive tape 93b, and the adhesive portion 93 is fixed to the T-covering portion 553. The attachment vertical frame 45 and the T-covering portion 553 form an intermediate member between the existing vertical frame 25 and the new vertical frame 35.

[0067] A wet sealant 94 is filled between one end of the outdoor cover material main body 91, which is closer to one end than the engaged portion 92, and the protruding plate 543a of the T-cover portion 543. A wet sealant 94 is filled between the other end of the outdoor cover material main body 91, which is closer to the other end than the adhered portion 93, and the protruding plate 553a of the T-cover portion 553.

[0068] This embodiment has the following advantages. The cover material 9 of this embodiment is attached to the exterior side X1 of the mullions 5 that make up the continuous window, and is positioned opposite the exterior side X1 of the mullions 5. This makes it possible to prevent the mullions 5 from being exposed to the exterior side X1 when the continuous window is a renovated fixture 1. This makes it possible to improve the design of the renovated fixture 1 that is made up of continuous window frames and mullions 5.

[0069] The cover material 9 of this embodiment has an outdoor cover material main body 91, an engaged portion 92 which is provided at one end of the outdoor cover material main body 91 in the facing direction and which engages and is fixed to an engaging portion 543b provided on a vertical frame cover portion 54 which is fixed to an attachment vertical frame 44 which serves as one-side intermediate member between the existing frame 2A as the one-side existing frame which constitutes the continuous window and the new frame 3A as the one-side new frame, and an adhered portion 93 which is provided at the other end of the outdoor cover material main body 91 in the facing direction and which is supported by being adhered to and fixed to the vertical frame cover portion 55 which is fixed to the attachment vertical frame 45 which serves as the other-side intermediate member between the existing frame 2B as the other-side existing frame which constitutes the continuous window and the new frame 3B as the other-side new frame.

[0070] This makes it possible to hide the entire exterior side X1 of the left and right mullions 5 on either side of the mullion 5 in the visible direction by covering it with the cover material 9. This makes it possible to prevent the exterior side X1 of the mullions 5 from being seen, and ensures an improvement in the design of the renovated fitting 1 made up of a row of windows with mullions 5.

[0071] Next, a second embodiment of the present disclosure will be described. In the second embodiment, the configuration of the cover material 9A differs from the configuration of the cover material 9 in the first embodiment. Accordingly, the configuration in which the cover material 9A is fixed differs from the configuration in which the cover material 9 is fixed in the first embodiment. Since the other configurations are the same as those in the first embodiment, the same reference numerals are used and the description will be omitted.

[0072] As shown in Fig. 4, the cover material 9A comprises an outdoor-covering material main body 91A, an engaged portion 92A, and a screw-fastened portion 93A. Like the outdoor-covering material main body 91, the outdoor-covering material main body 91A has a width greater than the width of the mullions 5 in the left-right direction across the mullions 5 in the view direction, and a length in the longitudinal direction of the outdoor-covering material main body 91A that is the same as the length of the mullions 5 in the longitudinal direction. A plurality of cutting grooves 911 are formed at predetermined intervals on the outdoor-side X1 surface of the outdoor-covering material main body 91A, extending parallel to the longitudinal direction of the outdoor-covering material main body 91A. The outdoor-covering material main body 91A is configured to be cut along the cutting grooves 911.

[0073] A rounded chamfer is formed in the portion of the outdoor cover material main body 91A that forms the opening of the cutting groove 911. This makes it possible to prevent sharp edges from forming at the cut edges when the outdoor cover material main body 91A is cut along the cutting groove 911. As a result, it becomes possible to prevent injury at the cut edges.

[0074] The engaged portion 92A extends from the edge of one end of the outdoor-covering material main body 91A toward the indoor side X2, bends toward the other end of the outdoor-covering material main body 91A (to the right in FIG. 4), extends one step toward the indoor side X2, and then extends again toward the other end of the outdoor-covering material main body 91A (to the right in FIG. 4) and has a hook-shaped portion 922A that is folded back toward the one end of the outdoor-covering material main body 91A. The hook-shaped portion 922A of the engaged portion 92 is engaged with and fixed to an engaging portion 543b formed by a portion of a T-shaped cover portion 543 fixed to the vertical attachment frame 44, closer to the mullion 5. A dry water-stop material 94A is provided between the portion 921A closer to the base than the hook-shaped portion 922A and the protruding plate 543a to provide a watertight seal therebetween.

[0075] The screwed portion 93A has a plurality of linear portions 931A extending from the surface of the outdoor cover material main body 91A facing the indoor side X2 to the indoor side X2 at the other end of the outdoor cover material main body 91A. The outdoor cover material main body 91A is cut, for example, along the cut line shown by the two-dot chain line in Figure 3, and the portion to the right of the cut line is removed as unnecessary.

[0076] The screwed portion 93A remaining on the exterior-covering material main body 91A, whose width in the front direction has been adjusted to an appropriate value in this way, is fixed by being screwed into the screwing part 95A. The screwing part 95A has an L-shaped portion 952A extending in both the front and front directions, a sealed portion 951A extending from the end of the L-shaped portion 952A on the indoor side X2 in the front direction toward the upright 5 (leftward in FIG. 4), and a hook-shaped portion 953A that is one step lower toward the indoor side X2 than the sealed portion 951A and extends toward the upright 5 (leftward in FIG. 4).

[0077] A dry water-stop material 94A is provided between the L-shaped portion 952A and the outer-cover material main body 91A to provide a watertight seal therebetween. The portion of the L-shaped portion 952A extending in the projection direction is fixed to the linear portion 931A with a screw 156A. A dry water-stop material 94A is provided between the sealed portion 951A and the protruding plate 553a to provide a watertight seal therebetween. The hook-shaped portion 953A engages with the engaging portion 543b and is fixed by screw 157A. By screwing in this manner, the screwed portion 93A can be more firmly fixed to the vertical attachment frame 45 via the screwing part 95A or the like compared to when adhesive tape 93b is used.

[0078] Next, a third embodiment of the present disclosure will be described. In the third embodiment, the configuration of the screw-received portion 92B of the cover material 9B differs from the configuration of the engaged portion 92A of the cover material 9A in the second embodiment. Accordingly, the configuration in which the cover material 9B is fixed differs from the configuration in which the cover material 9A is fixed in the second embodiment. Since the other configurations are the same as those in the second embodiment, the same reference numerals are used and the description will be omitted.

[0079] As shown in Fig. 5, the cover material 9B comprises an outdoor cover material main body 91B, a screw-receiving portion 92B, and a screw-receiving portion 93A. Like the outdoor cover material main body 91A, the outdoor cover material main body 91B has a width greater than the width of the mullions 5 in the left-right direction in the view direction, and has a length in the longitudinal direction of the outdoor cover material main body 91B that is the same as the length of the mullions 5 in the longitudinal direction.

[0080] The screwed portion 92B has a linear shape extending from the indoor side X2 surface of the outdoor cover material main body 91B toward the indoor side X2 at one end of the outdoor cover material main body 91B. The screwed portion 92B is fixed by being screwed into a screwing part 96B. The screwing part 96B has an L-shaped portion 961B extending in both the front and rear directions, a sealed portion 962B extending from the end of the L-shaped portion 961B on the indoor side X2 in the front direction toward the upright 5 (to the right in FIG. 4), and a hook-shaped portion 963B lowered one step toward the indoor side X2 than the sealed portion 962B and extending toward the upright 5 (to the right in FIG. 5).

[0081] A dry water-stop material 94A is provided between the L-shaped portion 961B and the outdoor-covering material main body 91B to provide a watertight seal therebetween. The portion of the L-shaped portion 961B extending in the projection direction is fixed to the screwed portion 92B with screws 158B. A dry water-stop material 94A is provided between the sealed portion 962B and the protruding plate 543a to provide a watertight seal therebetween. The hook-shaped portion 963B engages with the engaging portion 543b and is fixed by screwing with the screws 158B. This screwing allows the screwed portion 92B to be more firmly fixed to the vertical attachment frame 44 via the screwing parts 96B, etc., compared to when the hook-shaped portion 922A of the engaged portion 92 engages with the engaging portion 543b formed by the portion of the T-shaped cover portion 543 fixed to the vertical attachment frame 44 near the upright 5.

[0082] Next, a fourth embodiment of the present disclosure will be described. In the fourth embodiment, the configuration of the locked portion 92C of the cover material 9C differs from the configuration of the engaged portion 92A of the cover material 9A in the second embodiment. Accordingly, the configuration in which the cover material 9C is fixed differs from the configuration in which the cover material 9A is fixed in the second embodiment. Since the other configurations are the same as those in the second embodiment, the same reference numerals are used and the description will be omitted.

[0083] As shown in Fig. 6, the cover material 9C includes an outdoor-covering material main body 91C, a locking portion 92C, and a screw-receiving portion 93A. Like the outdoor-covering material main body 91A, the outdoor-covering material main body 91C has a width greater than the width of the upright 5 in the left-right direction across the upright 5 in the view direction, and a length in the longitudinal direction of the outdoor-covering material main body 91C that is the same as the length of the upright 5 in the longitudinal direction. Also, as shown in Fig. 7, when the distance between the new vertical frames 34, 35 is wide, the portion of the outdoor-covering material main body 91C where the screw-receiving portion 93A is provided is not cut out, and instead, the outdoor-covering material main body 91C is fixed to the new vertical frame 35 using the linear portion 931A of the screw-receiving portion 93A located on the other edge of the outdoor-covering material main body 91C, as in the second embodiment.

[0084] The locked portion 92C of the cover material 9C is locked to a screw-fastening part 96C serving as a locking part so as to be movable in the forward direction. Specifically, the locked portion 92C has an L-shape that extends toward the indoor side X2 at one end of the outdoor cover material main body 91C, bends, and extends toward one edge of the outdoor cover material main body 91C (to the left in FIG. 6). The outdoor cover material main body 91C and the locked portion 92C form a C-shape, and the tip locking portion 964C of the screw-fastening part 96C is inserted into the C-shape.

[0085] The screw fastening part 96C differs in configuration from the screw fastening part 96B of the third embodiment in that the tip of the end of the screw fastening part 96C on the exterior side X1 has a tip locking part 964C extending toward the interior side X2. Other than this, the configuration is the same as that of the screw fastening part 96B of the third embodiment. The tip locking part 964C is slidable relative to the locked part 92C. This allows the tip locking part 964C to slide relative to the locked part 92C as needed, even if slight dimensional errors occur in the cover material 9C or the structure that secures the cover material 9C, thereby absorbing the errors.

[0086] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified as appropriate. For example, the configuration of the cover material provided on the outdoor side X2 of the mullion 5 is not limited to the configuration of the cover material 9 in this embodiment. For example, the engaged portion may be provided on at least one end of the outdoor cover material main body in the facing direction. The adhesive portion may be provided on at least the other end of the outdoor cover material main body in the facing direction. The screwed portion may be provided on at least one end of the outdoor cover material main body in the facing direction. The screwed portion may be provided on at least the other end of the outdoor cover material main body in the facing direction. The locked portion may be provided on at least one end of the outdoor cover material main body in the facing direction. Furthermore, although the intermediate member is composed of the vertical attachment frame 44 and the T-shaped cover portion 543, etc., this configuration is not limited. [Explanation of symbols]
