[0009] A preferred embodiment of the renovation fitting according to the present invention will be described in detail below with reference to the attached drawings. In the following, for convenience, the terms "prospect direction" and "visible direction" may be used. The prospective direction is the direction along the depth of the fitting, as shown by arrow A in the figure. A surface along the prospective direction may be called a "prospect surface." The prospective direction is the direction along the top and bottom perpendicular to the prospective direction in the case of an object that extends along the horizontal direction, such as a sill. In the case of an object that extends along the vertical direction, such as a vertical frame, the direction along the horizontal direction perpendicular to the prospective direction is called the "prospect direction." A surface along the prospective direction may be called a "prospect surface."

[0010] 1 to 5 show fittings according to an embodiment of the present invention. The fittings shown here are doors used at the entrance of buildings such as detached houses, and in particular, a renovated entrance door that is installed while leaving the existing frame body 1 is shown. That is, in this entrance door, a new upper frame 11, lower frame 12, and left and right vertical frames 13 are installed on the inner periphery of the existing upper frame 1a, lower frame 1b, and left and right vertical frames 1c that are attached to the framework B, thereby forming a frame body 10 for supporting the door panel P so that it can be opened and closed. The new upper frame 11, lower frame 12, and left and right vertical frames 13 are extruded members formed from metals such as aluminum alloys, and are configured so that the portions along the entire length along the longitudinal direction have a substantially uniform cross-sectional shape. For convenience, in the following, the components of the existing frame body 1 that remain on the main body B will be referred to as "existing" (existing upper frame 1a, etc.), and the components of the newly installed frame body 10 will be referred to as "new upper frame 11, etc.) to distinguish between the two.

[0011] The new upper frame 11 and the new vertical frame 13 are connected by a resin bridge material 23 between the metal molding part on the outside of the room (hereinafter referred to as the outer metal molding part (first hollow part) 21) and the metal molding part on the inside of the room (hereinafter referred to as the inner metal molding part (second hollow part) 22). The outer metal molding part 21 and the inner metal molding part 22 each have a hollow shape with a substantially rectangular cross section. The inner metal molding part 22 has a door stop piece 22a on the inner peripheral part toward the inner circumference. The new upper frame 11 and the new vertical frame 13 having the above configuration are attached to the inner peripheral parts of the existing upper frame 1a and the existing vertical frame 1c via reinforcing metal fittings 24, respectively. Although not shown in the figure, the new upper frame 11 is attached between the expected inner peripheral surfaces of the left and right new vertical frames 13. An outer frame 30 is provided between the visible surfaces of the new upper frame 11 and the new vertical frame 13 facing the outside and the outer surface Wa of the exterior wall material W, while an inner frame 40 is provided between the visible surfaces of the new upper frame 11 and the new vertical frame 13 facing the inside of the room and the visible surface that is the inner periphery of the frame plate 25 on the framework side provided on the inside of the room. The outer frame 30 and the inner frame 40 are each extruded shapes formed from a metal such as an aluminum alloy.

[0012] On the other hand, the new sill 12 is attached to the existing sill 1b, which has been installed so that the difference in level with the porch surface 15 is almost zero, as a repair target. That is, as shown in Fig. 6, the existing sill 1b has an existing sill body 51 extending in the projection direction, and an existing door stop wall 52 extending in the projection direction from the edge of the existing sill body 51 on the interior side toward the inner periphery, and is installed so that the difference in level between the edge of the existing sill body 51 on the exterior side and the porch surface 15 is almost zero.

[0013] The new sill 12, which is to be used to repair the existing sill 1b, is composed of a new sill body (vertical frame facing portion) 12a, a new doorstop wall portion 12b, a door sill mounting plate portion 12c, and a support wall portion 12d. The new sill body 12a is a flat plate extending along the projection direction. The new doorstop wall portion 12b extends in the projection direction from the edge portion located on the interior side of the new sill body 12a toward the inner periphery. The protruding dimension of the new doorstop wall portion 12b toward the inner periphery is approximately equal to the protruding dimension of the existing doorstop wall portion 52 from the existing sill body 51 in the existing sill 1b. A sealant mounting portion 12e for mounting a sealant 16 is provided on the inner periphery edge portion of the new doorstop wall portion 12b facing the outside of the room. The door-sill mounting plate 12c extends from the new door-stop wall 12b toward the interior of the room in the front direction. Screw holes 12f are provided on the front surface of the door-sill mounting plate 12c, which is the outer periphery of the door-sill mounting plate 12c. The support wall 12d extends from the edge of the door-sill mounting plate 12c on the interior side of the room in the front direction. The extension dimension of the support wall 12d is approximately the same as that of the new door-stop wall 12b.

[0014] As shown in Figures 7 to 13, the new lower frame 12 has both ends of the new lower frame body 12a facing the lower surface of the new vertical frame 13, while the dimensions of the new door stop wall 12b, the door sill mounting plate 12c, and the support wall 12d are set so that they are located on the inner periphery side of the projected surface of the new vertical frame 13, and are disposed in the part that is the inner periphery side of the existing lower frame 1b. More specifically, the lower opening of the hollow part of the outer metal molding part 21 is closed by the new lower frame body 12a, while the lower opening of the hollow part of the inner metal molding part 22 is opened and directly faces the projected surface of the inner periphery side of the existing lower frame 1b. However, a drainage notch (drain hole) 12g is provided on the edge part located on the outside of the room of the new lower frame body 12a. To attach the new sill 12, stainless steel plates 17 are placed on both ends of the new sill body 12a, and screws 60 are screwed into the foundation of the entranceway through the stainless steel plates 17 and the new sill body 12a. The new sill 12 is connected to the existing sill 1b by screwing screws 61 into the existing sill 1b through the sill mounting plate 12c. After screwing the screws 61, a sill member 62 is attached to the sill mounting plate 12c.

[0015] After the new lower frame 12 is attached, the new vertical frame 13 is placed on the inner periphery of the existing vertical frame 1c, and the inner metal molding part 22 and the new lower frame 12 are connected by screwing a screw (not shown) into the screw hole 12f via the inner metal molding part 22. For the outer metal molding part 21, an L-shaped connecting plate 18 is placed in the hollow part, and the new lower frame main body 12a and the outer metal molding part 21 are connected via the connecting plate 18. If there is a gap between the new lower frame main body 12a and the existing lower frame 1b, a spacer 19 may be provided between them.

[0016] In the new frame body 10 constructed as described above, since the new lower frame body 12a is constructed in a flat plate shape, it is possible to install the new lower frame 12 with almost no step between it and the porch surface 15, in comparison with the existing lower frame 1b, which has almost no step between it and the porch surface 15. Moreover, water that has entered the hollow part of the outer metal molding part 21 is discharged to the outside of the room through the notch 12g provided in the new lower frame body 12a, and there is no risk of it accumulating inside. Similarly, water that has entered the hollow part of the inner metal molding part 22 is discharged directly through the opening on the bottom surface to the surface expected to be the inner periphery of the existing lower frame 1b, and then discharged to the outside of the room, and there is no risk of it accumulating inside.

[0017] In the above-described embodiment, a new vertical frame having two hollow portions is exemplified, but the present invention is not limited to this, and a new vertical frame having only one hollow portion may also be applied.

[0018] As described above, the renovation fittings of the present invention are fittings for renovation comprising a new frame body that is provided on the inner periphery of an existing frame body, and the new lower frame of the new frame body has a vertical frame opposing portion that is arranged opposite the underside of the new vertical frame, and the new vertical frame has a hollow portion that opens at its lower end, and the vertical frame opposing portion has a drainage hole in the portion corresponding to the hollow portion. According to this invention, water that has seeped into the hollow portion of the vertical frame is discharged to the outside through the drainage holes, so there is no concern that water will accumulate inside.

[0019] Furthermore, the present invention is characterized in that, in the above-mentioned renovation fitting, the vertical frame opposing portion is configured in a flat plate shape. According to this invention, it is possible to apply it to an existing sill frame with a small step between it and the porch surface.

[0020] The present invention is further characterized in that, in the above-mentioned renovation fittings, the hollow portion of the newly installed vertical frame has a first hollow portion on the outside of the room and a second hollow portion on the inside of the room, and the opposing portion of the vertical frame is arranged to cover the lower end opening of the first hollow portion and has the water drainage hole in a portion of it. According to this invention, water that has entered the first hollow portion is discharged to the outside through the water drainage hole, and there is no risk of water accumulating inside.

[0021] Furthermore, the present invention is characterized in that, in the above-mentioned renovation fitting, the vertical frame opposing portion is arranged so as to cover only the portion opposing the first hollow portion. According to this invention, water that has entered the second hollow portion is directly discharged to the outside, and there is no risk of water accumulating inside. [Explanation of symbols]
