[0009] The embodiments of the present invention will now be described based on the drawings. Figures 1 to 4 show the first embodiment of the renovation sash of the present invention (an embodiment of the invention according to claim 1). As shown in Figures 1 and 2, this renovation sash renovates the entrance door by leaving the existing frame 6 that is installed along the edge of the opening 12 of the building as is, installing a new frame (renovation frame) 1 on the inner circumference side thereof, and attaching a new door 13 to the renovation frame 1. This remodeled sash comprises a remodeling frame 1 attached to the inner circumference of the existing frame 6, a door 13 attached to the remodeling frame 1, a frame 14 attached to the exterior side around the opening 12, and an interior cover 15 attached to the interior side around the opening 12.

[0010] As shown in Figure 3, the door 13 is attached to the right-hand vertical frame 2a (when viewed from the outside) with hinges 16 so that it opens outwards. The hinges 16 are provided in three places: the top, middle, and bottom. Door 13 is equipped with a handle 17 on the leading edge side, a latch lock that is linked to the handle 17, and deadbolt locks 18a and 18b located above and below the handle 17. The door is locked by engaging the latch lock and deadbolt locks 18a and 18b with a lock receiver provided on the vertical frame 2b. A door closer (not shown) is provided on the upper part of the interior side of door 13. Reference numeral 19 in Figure 2 indicates a bracket for mounting the door closer.

[0011] As shown in Figures 1 and 2, the existing frame 6 is constructed by framing the existing upper frame 20 and existing lower frame 21, and the existing left and right vertical frames 7, 7, which are made of extruded aluminum alloy profiles, and is fixed to the building structure 9 with screws (not shown).

[0012] As shown in Figures 1-3, the renovation frame 1 is constructed by framing the upper frame 22, the lower frame 23, and the left and right vertical frames 2a and 2b. As shown in Figure 1, the vertical frames 2a and 2b are composed of an outdoor aluminum profile 3 made of an extruded aluminum alloy located on the outdoor side and an indoor resin profile 4 made of an extruded resin located on the indoor side, and are designed to provide thermal insulation. The outdoor aluminum profile 3 is formed in a hollow shape with a roughly rectangular cross-section, and a groove 24 is formed at the indoor end of the outer peripheral side surface, into which a reinforcing member 5, described later, engages. Furthermore, the outdoor aluminum profile 3 has a T-shaped engaging portion 25 and a groove-shaped engaging portion 26 formed on its indoor side surface, spaced apart in the inner and outer directions, for connecting to the indoor resin profile 4. A water-sealing material 27 is provided on the indoor side surface of the T-shaped engaging portion 25.

[0013] As shown in Figure 1, the indoor resin profile 4 has a main body portion 28 with a rectangular cross-section extending in the indoor-outdoor direction, a connecting portion 29 between the main body portion 28 and the outdoor aluminum profile 3 provided on the outdoor side of the main body portion 28, and a door stop portion 30 that protrudes from the inner circumference side of the main body portion 28. The main body 28 has a partition 31 inside, and multiple hollow sections 32 are arranged in a row in the direction of the interior and exterior. The connecting portion 29 consists of two projections 33 and 34 that protrude from the main body portion 28 toward the outside. The projection 33 on the inner circumference has a tip 33a that is bent toward the outer circumference in a hook shape, and this tip 33a engages with the T-shaped engaging portion 25 of the outdoor aluminum profile 3. The projection 34 on the outer circumference has a tip 34a that engages with the groove-shaped engaging portion 26 of the outdoor aluminum profile 3. Thus, the outdoor aluminum profile 3 and the indoor resin profile 4 are connected by engagement from both the indoor and outdoor directions. A sealing material 35 is attached to the door stop 30 facing outwards, and the sealing material 35 is in contact with the interior side of the door 13. An airtight seal 36 is attached to the outer end of the inner perimeter side of the indoor resin profile 4. The airtight seal 36 is in contact with or close to the leading edge and hinge side of the door 13.

[0014] As shown in Fig. 1, the outdoor aluminum profile 3 and the indoor resin profile 4 are connected by a reinforcing member 5 provided across the outer peripheral side surfaces of both profiles 3 and 4. The reinforcing member 5 is formed by pressing a metal plate such as steel, is formed in a plate shape extending in the indoor-outdoor direction, and a protruding piece 37 protruding inward on the inner peripheral side is formed at the intermediate portion in the indoor-outdoor direction. The reinforcing member 5 engages the protruding piece 37 with a groove 24 formed in the outdoor aluminum profile 3, screws the outdoor end portion to the outdoor aluminum profile 3 with a screw 38 from the outer peripheral side, and screws the intermediate portion in the indoor-outdoor direction to the indoor resin profile 4 with a screw 39 from the outer peripheral side for attachment. As shown in Fig. 4(b), the reinforcing member 5 is provided at intervals in the longitudinal direction of the vertical frames 2a and 2b over the entire length of the vertical frames 2a and 2b. By providing the reinforcing member 5 in this way, the outdoor aluminum profile 3 and the indoor resin profile 4 connected by engagement from the indoor-outdoor direction are integrated so as not to separate.

[0015] Fig. 5 shows the assembly procedure of the vertical frames 2a and 2b. First, as shown in Fig. 5(a), the tip 33a of the protruding piece 33 on the inner peripheral side of the indoor resin profile 4 is engaged with the T-shaped engaging portion 25 of the outdoor aluminum profile 3, rotated about the engaging portion 25 as a fulcrum, and the tip 34a of the protruding piece 34 on the outer peripheral side of the indoor resin profile 4 is engaged with the groove-shaped engaging portion 26 of the outdoor aluminum profile 3 to connect the outdoor aluminum profile 3 and the indoor resin profile 4. Next, as shown in Fig. 5(b), the protruding piece 37 of the reinforcing member 5 is engaged with the groove 24 of the outdoor aluminum profile 3, the reinforcing member 5 is abutted against the outer peripheral side surfaces of the outdoor aluminum profile 3 and the indoor resin profile 4, and screwed to the outdoor aluminum profile 3 and the indoor resin profile 4 respectively with screws 38 and 39 from the outer peripheral side.

[0016] After connecting the outdoor aluminum profile 3 and the indoor resin profile 4 with the reinforcing member 5 in this way, the vertical frames 2a and 2b are fixed to the housing 9 with a screw 8 passing through the reinforcing member 5 and the existing vertical frame 7 at a position closer to the indoor side of the main body portion 28 of the indoor resin profile 4 as shown in Fig. 1. The reinforcing member 5 is provided with a hole (a clearance hole) for passing the screw 8 in advance. A cover material 40 is attached to the indoor side of the door stop portion 30 of the indoor resin profile 4 to hide the through hole 41 of the screw 8 with the cover material 40.

[0017] As shown in FIG. 2, the upper frame 22 is composed of an outdoor aluminum profile 3 located on the outdoor side and an indoor resin profile 4 located on the indoor side, similar to the above-described vertical frames 2a and 2b. The outdoor aluminum profile 3 and the indoor resin profile 4 are connected by a reinforcing member 5 on the outer peripheral side. The indoor side of the indoor resin profile 4 is fixed to the building body 9 with a screw 8 that penetrates the reinforcing member 5 and the existing upper frame 20. Inside the hollow portion 32 of the indoor resin profile 4, a base metal fitting 42 for a door closer is provided by screwing it to the building body 9, and a bracket 19 for attaching a door closer is attached by screwing it to the base metal fitting 42 for a door closer.

[0018] In this way, in this retrofit sash, the reinforcing member 5 is provided across the outdoor aluminum profile 3 and the indoor resin profile 4 on the outer peripheral side of the vertical frames 2a, 2b and the upper frame 22, and the reinforcing member 5 is screwed to the outdoor aluminum profile 3 and the indoor resin profile 4 respectively, so that the outdoor aluminum profile 3 and the indoor resin profile 4 are firmly connected. Moreover, since the indoor side of the indoor resin profile 4 is fixed to the building body 9 with a screw 8 that penetrates the reinforcing member 5 and the existing vertical frame 7 and the existing upper frame 20, the outdoor aluminum profile 3 is connected to the building body 9 via the reinforcing member 5, and the movement and rotation of the outdoor aluminum profile 3 are restricted. As a result, this retrofit sash can have high strength while enhancing the heat insulation performance by forming the indoor sides of the vertical frames 2a, 2b and the upper frame 22 with resin profiles 4.

[0019] As shown in FIGS. 1 and 6(a), a bracket 43 is provided protruding to the outdoor side on the inner peripheral surface of the existing vertical frame 7 on the hanging side (the right side when viewed from the outdoor side). The bracket 43 is formed in a rectangular plate shape from a metal plate such as steel, and is attached by screwing it to the building body 9 with screws 44 from the inner peripheral side at two locations, the upper part and the lower part on the indoor side. As shown in FIG. 4, the bracket 43 is provided over the entire length of the vertical frame 2a at intervals in the longitudinal direction of the vertical frame 2a on the hanging side so as to overlap the reinforcing member 5. Also, as shown in FIG. 6(b), the bracket 43 is provided near the hinge 16 (especially the upper hinge 16).

[0020] As shown in Figures 1 and 6(b), the vertical frame 2a on the suspension side is fastened to the bracket 43 with screws 45 from the inner circumference side, using the outdoor aluminum profile 3. Also, as explained earlier, the indoor portion of the indoor resin profile 4 of the vertical frame 2a is fastened to the building structure 9 with screws 8 that pass through the reinforcing material 5 and the existing vertical frame 7, but the bracket 43 is pre-made with holes (oversized holes) 46 for passing these screws 8 through (see Figures 4 and 6).

[0021] When the door 13 is opened and closed, a large force is applied to the area around the hinge 16 of the vertical frame 2a on the hinge side (especially around the upper hinge 16). However, in this remodeled sash, as described above, a bracket 43 is provided on the inner side of the existing vertical frame 7 on the hinge side, protruding outwards, and the outdoor aluminum profile 3 is screwed to the bracket 43. This suppresses deformation of the vertical frame 2a when the door 13 is opened and closed, and further enhances the strength performance.

[0022] As shown in Figure 1, the door 13 has structural members 47 arranged in a frame shape around all four sides, with insulating material 48 made of expanded polystyrene or the like placed inside, and exterior side material 49a and interior side material 49b made of steel plates attached to the exterior and interior sides, respectively. The structural frame 47 is formed from a resin structural frame 47a with a roughly U-shaped cross-section and a roughly U-shaped metal structural frame 47b, which is positioned on the inner circumference of the resin structural frame 47a and has a smaller depth than the resin structural frame 47a. The metal structural frame 47b is positioned closer to the exterior side, and insulation material 50 is also placed between the interior wall of the resin structural frame 47a and the interior wall of the metal structural frame 47b. This further enhances the thermal insulation performance of the door 13.

[0023] As shown in Figures 1-3, the frame 14 is formed in a U-shape by vertical frames 14a, 14a provided along the left and right vertical frames 2a, 2b and a horizontal frame 14b provided along the top frame 22. As shown in Figures 1 and 2, the vertical frames 14a, 14a and the horizontal frame 14b are formed from extruded aluminum alloy profiles with a roughly U-shaped cross-section that is open on the indoor side. Mounting parts 51 that protrude on the inner circumference abut against the outdoor surfaces of the vertical frames 2a, 2b and the top frame 22, and are attached by screwing them in place with screws 52 from the outdoor side. A cover plate 53 is fitted onto the mounting part 51 from the outdoor side, and the cover plate 53 hides the screws 52. The vertical frames 14a, 14a and the horizontal frames 14b are provided with folding grooves 55 at intervals in the depth direction on the inner surface of the outer perimeter wall 54, allowing the length of the outer perimeter wall 54 to be adjusted by folding them appropriately in the folding grooves 55 according to the position of the outer wall 56. By installing the frame 14 in this way, the gap between the renovation frame 1 and the exterior wall 56 is hidden by the frame 14.

[0024] As shown in Figures 1 and 2, the interior cover 15 has a horizontal cover material 15b provided on the interior side of the upper frame 22 of the renovation frame 1 along the longitudinal direction of the upper frame 22, and vertical cover materials 15a, 15a provided on the interior side of the left and right vertical frames 2a, 2b of the renovation frame 1 along the longitudinal direction of the vertical frames 2a, 2b. The horizontal cover material 15b hides the existing upper frame 20, and the vertical cover materials 15a, 15a hide the existing vertical frames 7, 7. The horizontal cover material 15b and the vertical cover materials 15a, 15a are made of aluminum profiles with the same roughly L-shaped cross-section, having an inner wall 57 and a facing wall 58. The inner wall 57 and the facing wall 58 are each provided with a folding groove 55, allowing the length to be adjusted by folding them as needed using the folding groove 55. After adjusting the lengths of the recessed wall 57 and the facing wall 58, the horizontal cover material 15b and the vertical cover material 15a,15a are attached to the building structure 9 with screws 59 from the inner side, with the tip of the recessed wall 57 abutting against the interior side of the renovation 1 and the tip of the facing wall 58 abutting against the inner side of the building structure 9.

[0025] Next, we will explain the installation procedure for this renovated window frame. First, as shown in Figure 6(a), the bracket 43 is attached to the inner side of the existing vertical frame 7 on the hanging side by screwing it to the structure 9 with screws 44 from the inner side. Next, the framed renovation frame 1 is placed on the inner side of the existing frame 6 from the outside, the vertical frames 2a and 2b and the upper frame 22 are screwed to the building structure 9 with screws 8 from the inner side, and the lower frame 23 is screwed to the existing lower frame 21 with screws 60 from the inner side (see Figures 1, 2, 6(b)). At this time, the screws 8 that fix the vertical frames 2a and 2b and the upper frame 22 to the building structure 9 pass through the reinforcing material 5 and the existing vertical frame 7 and existing upper frame 20 and are screwed into the building structure 9. The screws 8 that fix the vertical frame 2a on the hanging side to the building structure 9 pass through the reinforcing material 5 and the existing vertical frame 7 as well as the bracket 43 and are screwed into the building structure 9. Then, as shown in Figures 1 and 6(b), the outdoor aluminum profile 3 of the vertical frame 2a on the suspension side is screwed to the bracket 43 with screws 45 from the inner circumference side. Next, attach the frame 14 to the exterior side of the renovation frame 1 and the interior cover 15 to the interior side. Finally, attach door 13 to renovation frame 1 using hinge 16.

[0026] Figures 7-10 show a second embodiment of the renovation sash of the present invention (an embodiment of the invention according to claim 2). As shown in Figures 7 and 8, the remodeled sash consists of vertical frames 2a and 2b of the remodel frame 1 and an upper frame 22, which are made of extruded aluminum alloy profiles, specifically an exterior aluminum profile 10a and an interior aluminum profile 10b, and an insulating bridge material 11 connecting the two aluminum profiles 10a and 10b. As shown in Figures 7 and 9, a reinforcing member 5 is provided on the outer periphery of the vertical frame 2a on the hanging side, spanning the outer periphery of the outdoor aluminum profile 10a and the indoor aluminum profile 10b. The reinforcing member 5 is attached to the outdoor aluminum profile 10a and the indoor aluminum profile 10b by screwing it in with screws 38 and 39 from the outer periphery. The reinforcing member 5 is provided near the hinge 16 in the upper and middle sections of the vertical frame 2a on the hanging side.

[0027] As shown in Figures 7 and 10, brackets 43 are provided on the inner side of the existing vertical frame 7 on the hanging side, protruding outwards, similar to the first embodiment. The outdoor aluminum profile 10a of the vertical frame 2a on the hanging side of the renovation frame 1 is screwed to the brackets 43 with screws 45 from the inner side. As shown in Figure 9, the brackets 43 are provided at intervals along the longitudinal direction of the vertical frame 2a, extending along the entire length of the vertical frame 2a. The reinforcing member 5 is positioned to overlap with the brackets 43.

[0028] As shown in Figures 7 and 10(b), the vertical frames 2a and 2b of the renovation frame 1 are screwed to the building structure 9 with screws 8 from the inner circumference side on the indoor aluminum profile 10b, and the screws 8 that fix the vertical frame 2a on the hanging side to the building structure 9 are screwed into the building structure 9 by passing through the reinforcing material 5, bracket 43 and existing vertical frame 7.

[0029] In the second embodiment of the remodeled sash, the vertical frames 2a, 2b and the upper frame 22 of the remodeled frame 1 are composed of an exterior aluminum profile 10a and an interior aluminum profile 10b made of extruded aluminum alloy, and an insulating bridge material 11 connecting the two aluminum profiles 10a and 10b, thereby improving the thermal insulation performance. Furthermore, the vertical frame 2a on the hinge side of the renovation frame 1 is connected to the exterior aluminum profile 10a and the interior aluminum profile 10b by a reinforcing member 5 at the upper and middle hinges 16, and the vertical frame 2a is screwed to the building structure 9 with screws 8 that pass through the reinforcing member 5 and the existing vertical frame 7. This suppresses deformation of the vertical frame 2a on the hinge side when the door 13 is opened and closed, thereby improving strength performance. Furthermore, by attaching a bracket 43 to the existing vertical frame 7 on the suspension side so that it protrudes outwards, and screwing the outdoor aluminum profile 10a of the vertical frame 2a to the bracket 43, the strength performance can be further improved.

[0030] As described above, this remodeled sash (first embodiment) is equipped with a remodeling frame 1 installed on the inner circumference side of the existing frame 6. The vertical frames 2a and 2b of the remodeling frame 1 are composed of an aluminum profile 3 on the exterior side and a resin profile 4 on the interior side. A reinforcing member 5 is provided spanning the outer periphery of the aluminum profile 3 and the resin profile 4 on the interior side. The resin profile 4 on the interior side is fixed to the building structure 9 with screws 8 that penetrate the reinforcing member 5 and the existing vertical frame 7 (see Figure 1). This improves both thermal insulation performance and strength performance.

[0031] This remodeled sash (second embodiment) includes a remodeling frame 1 installed on the inner circumference side of the existing frame 6. The vertical frame 2a of the remodeling frame 1 is composed of exterior and interior aluminum profiles 10a and 10b and an insulating bridge material 11 connecting the two aluminum profiles 10a and 10b. A reinforcing material 5 is provided spanning the outer circumference sides of the exterior aluminum profile 10a and the interior aluminum profile 10b. The interior aluminum profile 10b is fixed to the building structure 9 with screws 8 that penetrate the reinforcing material 5 and the existing vertical frame 7 (see Figure 7), thereby improving both thermal insulation performance and strength performance.

[0032] In this remodeled sash (first and second embodiments), a bracket 43 is provided on the inner side of the existing vertical frame 7, protruding outwards, and the outdoor aluminum profile 3,10a is screwed to the bracket 43 (see Figures 1 and 7), thereby further improving the strength performance. The bracket 43 is located near the upper hinge 16 (see Figures 6 and 10), which effectively suppresses deformation of the vertical frame 2a on the hinge side when the door 13 is opened and closed.

[0033] The present invention is not limited to the embodiments described above. The cross-sectional shapes of the exterior aluminum profile, the interior resin profile, and the interior aluminum profile can be changed as appropriate.
