The left and right vertical frames 23, 24 are fixed by fastening vertical frame mounting screws 62 to the outdoor portions 332, 342 of the existing vertical frames 33, 34. The left and right vertical frames 23, 24 each have a vertical frame packing attachment portion 23a, 24a that extends toward the inside of the door body 4, and a seal packing 91 is attached to the vertical frame packing attachment portions 23a, 24a in the same manner as the upper frame 21 and the lower frame 22.

[0026] As shown in FIGS. 2 and 3, the inner frame 25 extends from the inner surface of the door frame 2 toward the indoor side X2 and is provided on three sides of the upper frame 21 and the left and right vertical frames 23 and 24. The inner frame 25 is arranged to cover a part of the indoor side X2 of the existing door frame 3 and a part of the indoor side edge member 114.

[0027] The inner frame 25 has an inner frame inner surface 251 and an indoor side side surface portion 252. The inner frame inner surface 251 is a flat plate-shaped surface extending from the outdoor side X1 toward the indoor side X2. The indoor side side surface portion 252 is a flat plate-shaped surface bent vertically from the inner frame inner surface 251. The inner frame 25 is fixed to the indoor side edge member 114 by screws.

[0028] The outer frame 5 is a frame member connected to the upper frame 21 and the left and right vertical frames 23 and 24 and attached to cover the outdoor portions 312, 332, and 342 of the existing door frame 3. The outer frame 5 has a substantially U-shaped cross-sectional shape. The outer frame 5 has a linear vertically long shape attached to the door frame 2 along the opening edge 102 of the opening 101 of the fitting 1. The outer frame 5 has a decorative surface portion 51, a length adjustment portion 52, and a fitting portion 53. The outer frame 5 is formed of, for example, an aluminum material.

[0029] The decorative surface portion 51 is arranged to cover at least a part of the visible surface of the door frame 2. The decorative surface portion 51 has a substantially U-shaped cross-sectional shape and is arranged to cover the outdoor portions 312, 332, and 342 of the existing door frame 3.

[0030] The length adjustment portion 52 is a vertically long flat plate-shaped member connected to the outer ends of the decorative surface portion 51 in the visible direction on the vertical frames 23 and 24 and the upper end portion of the decorative surface portion 51 on the upper frame 21 and extending to cover the expected direction of the fitting 1. The length adjustment portion 52 is arranged such that its longitudinal direction is along each side of the opening edge 102.

[0031] The fitting portion 53 is formed on the decorative surface portion 51 and the length adjustment portion 52, respectively, and is configured to be connectable to each other.

[0032] The flat plate member 7 for adjustment (adjustment member, flat plate) is provided on the surface of the indoor side frame member 114 in a state where its length is adjusted, as shown in FIGS. 2 and 3. The flat plate member 7 for adjustment is configured as an adjustment member so that its length can be adjusted according to the fit at the site and can be generally used in various locations.

[0033] The flat plate member 7 for adjustment is arranged, for example, to cover a portion that cannot be covered by the inner frame 25 on the surface of the indoor side frame member 114 or a gap between members. In the present embodiment, the flat plate member 7 for adjustment is a rectangular flat plate having a thickness, having a predetermined width, and formed in a long shape. Both one surface and the other surface of the flat plate member 7 for adjustment are formed in a planar shape. The flat plate member 7 for adjustment is formed of, for example, an aluminum material. For example, the flat plate member 7 for adjustment is formed using a mold.

[0034] As shown in FIG. 4, the flat plate member 7 for adjustment has a plurality of cutting grooves 71. The plurality of cutting grooves 71 are arranged apart in the longitudinal direction of the flat plate member 7 for adjustment and are formed in a groove shape extending linearly across the entire width direction of the flat plate member 7 for adjustment. The cutting groove 71 is formed to be recessed in a U shape in the thickness direction from one surface. The flat plate member 7 for adjustment can be adjusted to an arbitrary length by cutting it with an arbitrary cutting groove 71.

[0035] As shown in FIG. 5, both ends of the open side of the U shape of the cutting groove 71 are arranged on the front side, and the closed side portion of the U shape is arranged on the back side. The cross-sectional shape of the cutting groove 71 is formed in a shape symmetric about a virtual cutting line L when the flat plate member 7 for adjustment is cut along the thickness direction.

[0036] When the adjustment flat plate member 7 is cut along the length direction and the thickness direction, the cutting concave groove 71 has a pair of front-side end curved portions 711, 711 formed at both ends on the open side of the U shape, a rear-side curved portion 713 formed on the closed side of the U shape, and a pair of straight portions 712, 712 that connect the pair of front-side end curved portions 711, 711 and the rear-side curved portion 713 and extend linearly.

[0037] The ratio (D / T) of the depth D of the cutting concave groove 71 to the thickness T of the adjustment flat plate member 7 is, for example, 0.3 to 0.5. The thickness T of the adjustment flat plate member 7 is the length from the front-side end face 701 to the rear-side end face 702 in the thickness direction of the adjustment flat plate member 7. The depth D of the cutting concave groove 71 is the distance from the front-side end face 701 to the rearmost end of the rear-side curved portion 713 in the thickness direction of the adjustment flat plate member 7.

[0038] The depth D of the cutting concave groove 71 is set in consideration of the length E of the remaining portion with respect to the thickness T of the adjustment flat plate member 7 in the direction along the cutting planned virtual line L at the longitudinal position of the adjustment flat plate member 7 where the cutting concave groove 71 is formed. By increasing the length E of the remaining portion with respect to the thickness T of the adjustment flat plate member 7, the strength of the adjustment flat plate member 7 when not cut in the cutting concave groove 71 is ensured, and by decreasing the length E of the remaining portion with respect to the thickness T of the adjustment flat plate member 7, the ease of cutting is realized. In the present embodiment, the thickness T of the adjustment flat plate member 7 is, for example, 1.6 to 2.2 cm, and the depth D of the cutting concave groove 71 is, for example, 0.6 to 1.0 cm.

[0039] The pair of front-side end curved portions 711 of the cutting concave groove 71 are each formed in an arc shape that protrudes forward at the front-side end of the cutting concave groove 71. The front-side end curved portion 711 is formed by an arc of a circle with a radius of curvature r1 of, for example, 0.1 to 0.3 cm.

[0040] The back curved portion 713 of the cutting concave groove 71 is formed in an arc shape that is concave toward the back on the back side of the cutting concave groove 71. The back curved portion 713 is constituted by, for example, a part of an arc of a circle with a diameter R. The back curved portion 713 is formed by, for example, an arc of a circle with a curvature radius r2 of 0.6 to 1.0 cm.

[0041] The pair of straight portions 712, 712 extend linearly at an angle of 90° with respect to the long sides (the front end face 701 and the back end face 702) of the adjustment flat plate member 7. One of the pair of straight portions 712, 712 extends linearly from one of the front end curved portions 711 to one end of the back curved portion 713. The other of the pair of straight portions 712, 712 extends linearly from the other front end curved portion 711 to the other end of the back curved portion 713.

[0042] The case of cutting the adjustment flat plate member 7 in the cutting concave groove 71 will be described. As shown in FIG. 6, when cutting the adjustment flat plate member 7 at an arbitrary position in the longitudinal direction, in the cutting concave groove 71 to be cut, the tip of the blade of the cutter 10 is inserted into the innermost part of the back curved portion 713, and the blade of the cutter 10 is moved backward along the virtual cutting line L. Thereby, a part on the back side of the back curved portion 713 in the cutting concave groove 71 is cut to form a cutter cut portion 713a.

[0043] In this case, since the pair of straight portions 712 are provided in the cutting concave groove 71, the tip of the cutter 10 can be guided to the straight portion 712 and inserted smoothly rather than being formed only by an arc. Thereby, the adjustment flat plate member 7 can be easily cut.

[0044] Next, as shown in FIG. 7, using the cutting groove 71 and the cutter cutting portion 713a, the adjusting flat plate member 7 is bent by the pliers 11 so as to be cut and folded along the virtual cutting line L of the adjusting flat plate member 7 to be cut. Thereby, in the cutting groove 71 and the cutter cutting portion 713a, it can be folded by the pliers 11 along the virtual cutting line L to be cut. In this way, the length of the adjusting flat plate member 7 can be adjusted to an arbitrary length.

[0045] Here, since a pair of straight portions 712 are provided in the cutting groove 71, the cutting groove 71 is formed with a greater depth on the back side than when the cutting groove is formed only of an arc. Therefore, the cuttability can be improved by increasing the depth D of the cutting groove 71 on the back side and reducing the length E of the remaining portion of the adjusting flat plate member 7.

[0046] According to the present embodiment, the following effects are obtained. The adjusting flat plate member 7 of the present embodiment is a plate-shaped adjusting member for a modified fitting that has a plurality of cutting grooves 71 and can adjust its length by cutting with an arbitrary cutting groove 71. The cutting groove 71 is formed to be recessed in a U shape in the thickness direction from the surface, and in a cross section when cut along the length direction, it has a pair of front end curved portions 711, a back curved portion 713, and a pair of straight portions 712 that connect the pair of front end curved portions 711 and the back curved portion 713 and extend linearly.

[0047] Accordingly, by providing the straight portion 712 between the front end curved portion 711 and the rear curved portion 713 in the cutting concave groove 71, the depth of the cutting concave groove 71 can be increased. Therefore, in the longitudinal position of the adjusting flat plate member 7 where the cutting concave groove 71 is formed, the length E of the remaining portion can be reduced with respect to the thickness T of the adjusting flat plate member 7. Thereby, the cutting of the adjusting flat plate member 7 by a cutter or the like can be easily performed. Further, since the cutting concave groove 71 has a pair of straight portions 712, it serves as a guide when inserting a cutter or the like, so that the cutting of the adjusting flat plate member 7 can be easily performed. Also, since the cutting concave groove 71 has a pair of straight portions 712, when forming the adjusting flat plate member 7 using a mold, it is easy to manufacture the extrusion die (die) of the mold, so that the manufacturing cost of the adjusting flat plate member 7 can be reduced.

[0048] Also, in the present embodiment, the ratio (D / T) of the depth D of the cutting concave groove 71 to the thickness T of the adjusting flat plate member 7 is 0.3 to 0.5. Thereby, it is easy to cut the adjusting flat plate member 7 in the cutting concave groove 71, and the strength of the adjusting flat plate member 7 in the cutting concave groove 71 can be ensured.

[0049] Also, in the present embodiment, the adjusting flat plate member 7 is composed of flat plates on both the one surface and the other surface. Thereby, when used for the refitting fitting 1, it is easy to handle.

[0050] Also, in the present embodiment, the cross-sectional shape of the cutting concave groove 71 is formed in a shape symmetric with respect to the virtual cutting line L when cutting the adjusting flat plate member 7 along the thickness direction. Thereby, it is not necessary to distinguish between the left and right directions of the adjusting flat plate member 7, so that it is easy to handle.

[0051] Note that the present disclosure is not limited to the above embodiment, and modifications, improvements, etc. within the scope that can achieve the object of the present disclosure are included in the present disclosure.

[0052] For example, in the above embodiment, the adjustment member has been described when applied to the flat plate member for adjustment (flat plate), but it is not limited thereto. The adjustment member may be applied to the inner frame or the outer frame. For example, the adjustment member may be applied to the length adjustment portion 52 of the outer frame 5 in the above embodiment.

[0053] Also, in the above embodiment, the adjustment member is constituted by a flat plate, but it is not limited thereto. The adjustment member is not limited to a long flat plate having a thickness, and for example, an L-shaped member may be used. Further, both the one surface and the other surface of the adjustment member do not have to be flat plates, and for example, unevenness may be formed on the surface.
