AI Technical Summary
New frame members in renovation projects often protrude outward, making them susceptible to deformation due to external forces, especially when panels are in the open position, which can exacerbate the issue.
The renovation fittings attach a fixing bracket to the outer side of the new frame material, allowing it to protrude inside the room, and secure it to the main body with an inner fixing device, while the new frame material is attached to the existing frame via an outer fixing device, optionally with a frame reinforcement for added stability.
This configuration prevents deformation of newly installed frame materials by distributing external forces effectively, ensuring stability and durability.

Abstract
Description
[Technical Field]
[0001] The present invention relates to a renovation fitting that has a new frame member of a new frame body on the inner periphery of an existing frame member attached to a main body. [Background technology]
[0002] One method of renovating fixtures involves attaching new frame members to the inner periphery of the existing frame members while leaving the existing frame members in place. In this type of renovation method, fixing brackets are attached to the outer periphery of the new frame members so that they protrude further into the room than the new frame members, and fixing devices such as screws are attached to the frame via the fixing brackets, so that the new frame members are attached to the frame via the fixing brackets (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-204291 Summary of the Invention [Problem to be solved by the invention]
[0004] However, new frame members are often larger in the projection direction than existing frame members and are installed so that they protrude toward the exterior compared to the existing frame members. This makes them more susceptible to external forces, raising concerns that the new frame members may be deformed. In particular, in the case of new frame members that have support members such as hinges between them and panels such as doors, the panel load is applied through the support members when the panel is placed in the open position, which may exacerbate the above-mentioned problems.
[0005] In view of the above-mentioned circumstances, the present invention aims to provide a renovation fitting that can prevent deformation of newly installed frame materials. [Means for solving the problem]

[0009] A preferred embodiment of the renovation fittings according to the present invention will be described in detail below with reference to the accompanying drawings. Note that, for convenience, the terms "prospect direction" and "visibility direction" will be used below. The prospect direction is the direction along the depth of the fittings, as indicated by arrow A in the drawings. A surface along the prospect direction will sometimes be referred to as a "prospect surface." The prospect direction is the direction perpendicular to the prospect direction in the case of an item that extends horizontally, such as a top frame. In the case of an item that extends vertically, such as a vertical frame, the horizontal direction perpendicular to the prospect direction is called the "prospect direction." A surface along the prospect direction will sometimes be called a "prospect surface."
[0010] (Embodiment 1) 1 to 3 show a fitting for renovation according to a first embodiment of the present invention. The fitting for renovation exemplified here is a door used at the entrance of a building such as a detached house, and in particular, an entrance door for renovation that is installed while leaving the existing frame body 1 in place is exemplified. That is, in this entrance door, a new upper frame (new frame material) 11, a lower frame 12, and left and right vertical frames (new frame materials) 13, 14 for renovation are installed on the inner periphery of the existing upper frame (existing frame material) 1a, lower frame 1b, and left and right vertical frames (existing frame material) 1c that are attached to the skeleton B, thereby forming a frame body 10 for supporting a door panel 15 so that it can be opened and closed. The new upper frame 11 and left and right vertical frames 13, 14 each have an exterior metal frame section 11A, 13A, 14A made of metal such as aluminum alloy and an interior resin frame section 11B, 13B, 14B made of resin. The metal frame sections 11A, 13A, 14A and the resin frame sections 11B, 13B, 14B are interconnected. The metal frame sections 11A, 13A, 14A and the resin frame sections 11B, 13B, 14B are each extruded profiles with a substantially uniform cross-sectional shape along their entire length. The new lower frame 12, on the other hand, has an interior frame section 12A and an exterior frame section 12B made of metal such as aluminum alloy and a bridge member 12C made of insulating material. The interior frame section 12A and the exterior frame section 12B are connected via the bridge member 12C. Although not shown in the drawings, door panel 15 is a so-called flush panel, constructed by arranging surface materials on frameworks that are framed all around. Although not shown in the drawings, in this embodiment 1, when viewed from the inside of the room, the vertical frame located on the left side (hereinafter referred to as left vertical frame 13 for distinction) serves as the hanging point, and the vertical frame located on the right side (hereinafter referred to as right vertical frame 14 for distinction) serves as the door edge, with hinge 16 provided between door panel 15.
[0011] 4 to 9 show the upper frame portion and vertical frame portion of the renovation fittings. Below, with reference to the drawings, we will mainly describe in detail the detailed configuration of the existing upper frame 1a and vertical frame 1c, the new upper frame 11 and vertical frames 13, 14, and the mounting structure of the upper frame 11 and vertical frames 13, 14, and also explain the characteristics of the present invention. For convenience, the components of the existing frame body 1 attached to the skeleton B will be referred to as "existing," such as "existing upper frame," and the components of the newly installed frame body 10 will be referred to as "newly installed," such as "new upper frame," to distinguish between the two.
[0012] As shown in Figures 4 and 5, the existing upper frame 1a has an existing upper main body 1aa, an existing upper door stop wall 1ab, an existing upper outer peripheral hollow 1ac, and an existing upper mounting wall 1ad. The existing upper main body 1aa is a flat plate extending approximately horizontally along the projection direction. The existing upper door stop wall 1ab protrudes inward from the portion of the projection surface on the inner periphery of the existing upper main body 1aa that is closer to the interior of the room. The portion of the existing upper door stop wall 1ab that faces the outside of the room is provided with an existing upper sealing material mounting portion 1ae that protrudes toward the outside. The existing upper outer peripheral hollow 1ac protrudes toward the outside from the portion of the projection surface on the outer periphery of the existing upper main body 1aa that is closer to the exterior of the room, and is configured to have a cylindrical cross section that is approximately square. The existing upper mounting wall 1ad extends from the corner on the indoor side of the outer periphery of the existing upper outer peripheral hollow portion 1ac toward the periphery. This existing upper frame 1a is attached to the skeleton B with the existing upper outer peripheral hollow portion 1ac protruding outside the room by abutting the visible surface of the existing upper outer peripheral hollow portion 1ac facing inside the room and the existing upper mounting wall 1ad against the surface of the skeleton B facing outside.
[0013] As shown in Figures 6 to 9, the existing vertical frames 1c are configured to be symmetrical on the left and right, each having an existing vertical main body 1ca, an existing vertical doorstop wall 1cb, an existing vertical outer peripheral hollow portion 1cc, and an existing vertical mounting wall 1cd. The existing vertical main body 1ca is a flat plate extending approximately vertically along the projection direction. The existing vertical doorstop wall 1cb protrudes inward from the portion of the projection surface on the inner periphery of the existing vertical main body 1ca that is closer to the interior of the room. The portion of the existing vertical doorstop wall 1cb that faces the outside of the room is provided with an existing vertical seal material mounting portion 1ce that protrudes toward the outside. The existing vertical outer peripheral hollow portion 1cc protrudes toward the outside of the room from the portion of the projection surface on the outer periphery of the existing vertical main body 1ca that is closer to the exterior of the room, and is configured to have a cylindrical cross section. The existing vertical mounting wall 1cd extends from the corner facing the room on the outer periphery of the existing vertical outer periphery hollow section 1cc toward the periphery. The left and right existing vertical frames 1c are attached to the body B in a state where the existing vertical outer periphery hollow section 1cc protrudes outside the room by abutting the visible surface of the existing vertical outer periphery hollow section 1cc facing inside the room and the existing vertical mounting wall 1cd against the surface of the body B facing outside. The dimension of the existing vertical frame 1c along the projection direction is approximately equal to the dimension of the existing upper frame 1a along the projection direction.
[0014] The new upper frame 11, which is to be used to repair the existing upper frame 1a, has a metal frame portion 11A and a resin frame portion 11B as described above. As shown in Figures 4 and 5, the metal frame portion 11A of the new upper frame 11 has a new upper outer frame body 11a that is tubular and has a substantially rectangular cross section. A new upper locking piece 11b extending toward the room is provided at the corner located on the indoor side of the outer periphery of the new upper outer frame body 11a. A new upper outer hook portion 11c extending toward the room and then bending toward the outer periphery is provided at the corner located on the indoor side of the inner periphery of the new upper outer frame body 11a. The resin frame portion 11B of the new upper frame 11 has a new upper inner frame body 11d that is tubular and has a substantially rectangular cross section. The dimensions of the new upper inner frame body 11d along the projection direction are smaller than those of the new upper outer frame body 11a, but the dimensions along the projection direction are approximately equal to those of the new upper outer frame body 11a. A new upper door stop wall 11e is provided at the corner of the new upper inner frame body 11d, located on the interior side of the room. The new upper door stop wall 11e protrudes inward from the new upper inner frame body 11d and has a new upper sealant attachment portion 11f for attaching the seal member C1 on the portion facing the outside of the room. A storage section-constituting wall 11g is provided at the corner of the new upper inner frame body 11d, located on the interior side of the room, on the exterior side. The storage section-constituting wall 11g extends toward the interior and then bends toward the interior, forming a storage section 11h that opens toward the interior between the new upper inner frame body 11d and the new upper inner frame body 11d. At the corners of the new upper inner frame body 11d located on the outside of the room, new upper engagement claws 11i are provided on the outer periphery, and new upper inner hooks 11j are provided on the inner periphery. The new upper engagement claws 11i protrude toward the outer periphery and are provided to correspond to the new upper locking pieces 11b of the metal frame part 11A. The new upper inner hooks 11j extend toward the outside of the room and then bend toward the inner periphery, and are provided to correspond to the new upper outer hooks 11c of the metal frame part 11A.
[0015] The metal frame portion 11A and the resin frame portion 11B of the new upper frame 11 are interconnected by engaging the new upper outer hook portion 11c with the new upper inner hook portion 11j and by engaging the new upper locking piece 11b with the new upper locking claw portion 11i, and are further integrated by threading a screw S1 into the new upper outer frame body 11a via the new upper inner frame body 11d. Furthermore, upper frame fixing brackets (fixing brackets) 11C are attached to multiple locations along the length of the outer periphery of the new upper frame 11. The upper frame fixing brackets 11C are molded from a metal such as steel or aluminum alloy and have upper fixing pieces 11Ca and upper mounting pieces 11Cb. The upper fixing piece 11Ca is a flat plate extending from the metal frame 11A to the resin frame 11B, and is attached to the metal frame 11A of the new upper frame 11 by screwing in a screw S2 while abutting against the outer peripheral surfaces of the metal frame 11A and the resin frame 11B. The upper fixing piece 11Ca is also fastened to the resin frame 11B by a screw S3 for attaching the arm reinforcement 33 (described later) to the upper frame fixing bracket 11C. The upper mounting piece 11Cb extends from the interior edge of the upper fixing piece 11Ca toward the interior along the interior surface of the new upper frame 11, and then protrudes toward the interior from a position approximately halfway along the interior surface of the new upper frame 11.
[0016] The new vertical frames 13, 14, which are to be used to renovate the existing vertical frame 1c, are configured to be symmetrical on the left and right. As shown in Figures 6 to 9, the metal frame portions 13A, 14A have new vertical outer frame bodies 13a, 14a that are cylindrical and have a substantially rectangular cross section. New vertical locking pieces 13b, 14b extending toward the room are provided at the corners facing the interior of the room on the outer periphery of the new vertical outer frame bodies 13a, 14a. New vertical outer hook portions 13c, 14c and new vertical outer sealant mounting portions 13d, 14d are provided at the corners facing the interior of the room on the inner periphery of the new vertical outer frame bodies 13a, 14a. The new vertical outer hook portions 13c, 14c extend toward the room and then bend toward the outer periphery. The new vertical outer seal mounting portions 13d, 14d are for mounting the vertical outer seal member C2 and protrude toward the inner periphery. The resin frame portions 13B, 14B of the new vertical frames 13, 14 have new vertical inner frame bodies 13e, 14e with a roughly rectangular tubular cross section. The dimensions of the new vertical inner frame bodies 13e, 14e along the projection direction are smaller than those of the new vertical outer frame bodies 13a, 14a, and the dimensions along the projection direction are roughly equal to those of the new vertical outer frame bodies 13a, 14a. New vertical door stop walls 13f, 14f are provided at the corners of the new vertical inner frame bodies 13e, 14e on the inner periphery, facing the interior. The new vertical doorstop walls 13f, 14f protrude inward from the new vertical inner frame bodies 13e, 14e and have new vertical seal mounting portions 13g, 14g for mounting the seal member C3 on the exterior-facing portion. The interior side of the new vertical inner frame bodies 13e, 14e has new vertical inner hollow portions 13h, 14h. The new vertical inner hollow portions 13h, 14h have dimensions along the front-facing direction that are approximately the same as those of the new vertical inner frame bodies 13e, 14e, but are smaller in dimensions along the front-facing direction. The exterior-facing corners of the new vertical inner frame bodies 13e, 14e have new vertical engaging claw portions 13i, 14i on the outer periphery and new vertical inner hook portions 13j, 14j on the inner periphery. The newly installed vertical engaging claws 13i, 14i protrude outward and are provided to correspond to the newly installed vertical locking pieces 13b, 14b of the metal frame portions 13A, 14A. The newly installed vertical inner hook portions 13j, 14j extend outward and then bend inward, and are provided to correspond to the newly installed vertical outer hook portions 13c, 14c of the metal frame portions 13A, 14A.
[0017] The metal frame portions 13A, 14A and the resin frame portions 13B, 14B of these new vertical frames 13, 14 are connected to each other by engaging the new vertical outer hook portions 13c, 14c and the new vertical inner hook portions 13j, 14j with each other and by engaging the new vertical locking pieces 13b, 14b with the new vertical engaging claw portions 13i, 14i, and are further integrated by screwing S4 into the new vertical outer frame bodies 13a, 14a via the new vertical inner frame bodies 13e, 14e. Furthermore, vertical frame fixing brackets (fixing brackets) 13C, 14C are attached to the outer periphery of the new vertical frames 13, 14 at multiple locations in the longitudinal direction. The vertical frame fixing brackets 13C, 14C are formed from steel or aluminum alloy metal and include vertical fixing pieces 13Ca, 14Ca and vertical mounting pieces 13Cb, 14Cb. The vertical fixing pieces 13Ca, 14Ca are flat plates extending from the metal frame pieces 13A, 14A to the resin frame pieces 13B, 14B. They are attached to the new vertical frames 13, 14 by screwing screws S5 into the vertical fixing pieces 13Ca, 14Ca while abutting the outer surfaces of the metal frame pieces 13A, 14A and the resin frame pieces 13B, 14B. The vertical mounting pieces 13Cb, 14Cb extend from the interior edge of the vertical fixing pieces 13Ca, 14Ca along the interior surface of the new vertical frames 13, 14, and then protrude from the interior corners of the new vertical frames 13, 14 toward the room. The dimensions of the new vertical frames 13, 14 along the projection direction are approximately equal to the dimensions of the new upper frame 11 along the projection direction.
[0018] As shown in Figures 4 to 9, the above-mentioned new upper frame 11 and new vertical frames 13, 14 are attached to the main body B by screwing an internal screw (internal fixing device) S6 into the main body B via the upper mounting piece portion 11Cb protruding toward the interior side of the upper frame fixing bracket 11C and the vertical mounting piece portions 13Cb, 14Cb protruding toward the interior side of the vertical frame fixing brackets 13C, 14C.
[0019] More specifically, the new upper frame 11 includes an upper inner spacer (inner spacer) D1 that protrudes inward from the existing upper door stop wall 1ab on the interior side of the existing upper frame 1a, and an upper frame reinforcement (frame reinforcement) 20 and an upper outer spacer D2 that are located on the projected surface of the existing upper body 1aa. The upper frame reinforcement 20 is a flat plate made of metal such as steel or aluminum alloy, and is attached to the upper frame fixing bracket 11C by threading screws S7. As can be seen from the figure, the projected dimension of the upper frame reinforcement 20 is set to be approximately the same as the upper fixing piece 11Ca of the upper frame fixing bracket 11C. From the above-mentioned state, the upper fixing piece portion 11Ca of the upper frame fixing bracket 11C is abutted against the upper outer spacer D2, and an inner screw S6 is screwed into the main body B via the upper mounting piece portion 11Cb and the upper inner spacer D1, and an outer screw (external fixing device) S8 is screwed into the upper frame reinforcement material 20 via the metal frame portion 11A and upper fixing piece portion 11Ca of the new upper frame 11, thereby attaching the new upper frame 11 to the inner side of the existing upper frame 1a.
[0020] Similarly, for the new left vertical frame 13, which will serve as the hanging point, a vertical inner spacer (inner spacer) D3 is installed in the existing vertical frame 1c, protruding inward from the existing vertical doorstop wall 1cb, on the interior side of the existing vertical doorstop wall 1cb. A vertical frame reinforcement (frame reinforcement) 21 and a vertical outer spacer D4 are also installed on the projected surface of the existing vertical body 1ca, which will be the projected inner surface of the existing vertical body 1ca. The vertical frame reinforcement 21 is a flat plate made of metal such as steel or aluminum alloy, and is attached to the vertical frame fixing bracket 13C by threading screws S9. As can be seen from the figure, the projected dimension of the vertical frame reinforcement 21 is set to be approximately the same as the vertical fixing piece 13Ca of the vertical frame fixing bracket 13C. From the above-mentioned state, with the vertical fixing piece portion 13Ca abutting against the vertical outer spacer D4, an inner screw (inner fixing device) S10 is screwed into the main body B via the vertical mounting piece portion 13Cb and the vertical inner spacer D3, and an outer screw (outer fixing device) S11 is screwed into the vertical frame reinforcement material 21 via the metal frame portion 13A of the new left vertical frame 13 and the vertical fixing piece portion 13Ca, thereby attaching the new left vertical frame 13 to the inner side of the existing vertical frame 1c.
[0021] The new right vertical frame 14, which will be located on the door-end side, may be attached in the same manner as the new left vertical frame 13. However, in the first embodiment, the vertical frame reinforcement 21 is omitted and the new right vertical frame 14 is attached to the inner periphery of the existing vertical frame 1c. That is, a vertical inner spacer D3 that protrudes inward from the existing vertical doorstop wall 1cb is disposed in advance in the existing vertical frame 1c on the room side of the existing vertical doorstop wall 1cb, and a vertical outer spacer D4 is disposed on the surface that will become the inner periphery of the existing vertical main body 1ca. Then, with the vertical frame fixing bracket 13C abutting the vertical outer spacer D4, the new right vertical frame 14 is attached to the inner periphery of the existing vertical frame 1c by screwing the inner screw S10 into the frame B via the vertical mounting piece 14Cb and the vertical inner spacer D3.
[0022] Although not shown in the figure, the new sill 12 is attached to the existing sill 1b by threading screws S12 while positioned on the inner periphery of the existing sill 1b. A new door can be constructed on the inner periphery of the existing frame 1 by supporting a door panel 15 so that it can be opened and closed for the new frame 10 constructed as described above. New outer frames F are provided between the exterior wall E and the new upper frame 11, and between the exterior wall E and the new vertical frames 13 and 14, so as to cover the existing upper frame 1a and the existing vertical frames 1c, respectively. The upper frame fixing bracket 11C and upper inner spacer D1, and the vertical frame fixing brackets 13C and 14C and vertical inner spacer D3, which protrude into the interior of the room, are each covered by a new inner frame G.
[0023] 2, 4, and 5, a door closer 30 is attached between the new upper frame 11 and the door panel 15. The door closer 30 comprises a closer body 31 attached to the interior surface of the door panel 15, and an arm 32 connecting the closer body 31 and the new upper frame 11. In the example shown, an arm reinforcement member 33 is provided in a storage section 11h provided in the new upper frame 11, and the arm 32 is attached to the upper frame fixing bracket 11C via the arm reinforcement member 33. That is, the arm reinforcement member 33 is formed from steel and has a bracket connecting piece 33b on one edge of a reinforcing base plate 33a and an arm connecting piece 33c on the other edge of the reinforcing base plate 33a. This arm reinforcement 33 is attached to the upper frame fixing bracket 11C together with the resin frame portion 11B by threading a screw S3 into the upper fixing piece portion 11Ca via the bracket connecting piece 33b and the resin frame portion 11B of the new upper frame 11. A cover member 34 is attached to the opening of the accommodation portion 11h that accommodates the arm reinforcement 33. The arm 32 of the door closer 30 is attached to the upper frame fixing bracket 11C via the arm reinforcement 33 by threading a screw S13 into the arm connecting piece 33c via the cover member 34 while abutting against the inner periphery of the cover member 34.
[0024] In the renovation fittings configured as described above, the new upper frame 11 is attached to the skeleton B with inner screws S6 via upper mounting piece 11Cb that protrudes toward the room side of the upper frame fixing bracket 11C attached to the new upper frame 11. Furthermore, the metal frame portion 11A that faces the outside of the room is attached to the upper frame reinforcement 20 together with upper fixing piece 11Ca with outer screws S8. Similarly, the new left vertical frame 13 is attached to the skeleton B with inner screws S10 via vertical mounting piece 13Cb that protrudes toward the room side of the vertical frame fixing bracket 13C attached to the new left vertical frame 13. Furthermore, the metal frame portion 13A that faces the outside of the room is attached to the vertical frame reinforcement 21 together with vertical fixing piece 13Ca with outer screws S11. That is, the attachment strength of the new upper frame 11 and the new left vertical frame 13 to the frame B is improved by the upper frame fixing bracket 11C, the vertical frame fixing bracket 13C, the upper frame reinforcement 20, and the vertical frame reinforcement 21. Therefore, even if an external force is applied to the new upper frame 11 or the new left vertical frame 13 during the opening and closing operation of the door panel 15, it is possible to prevent deformation of each. Furthermore, the arm 32 of the door closer 30 has its tip attached to the upper frame fixing bracket 11C via the arm reinforcement 33 with the screw S13. Therefore, no external force is applied to the new upper frame 11 via the arm 32 during the opening and closing operation of the door panel 15 or the operation of the door closer 30, and there is no risk of deformation of the new upper frame 11.
[0025] In the first embodiment described above, the frame reinforcement is attached to the existing frame material, and the screws are screwed into the reinforced frame material via the fixing bracket, but the present invention is not limited to this, and the screws may be screwed into the existing frame material via the fixing bracket. In this case, it is not necessary to attach the frame reinforcement to the existing frame material.
[0026] (Embodiment 2) 10 and 11 show a renovation fitting according to a second embodiment of the present invention. The renovation fitting illustrated here is, as in the first embodiment, a door used at the entrance of a building such as a detached house, and in particular illustrates a front door for renovation that is installed while leaving the existing frame 2. That is, in this front door, a new upper frame (facility frame material) 11 for renovation, a new lower frame 12, and new left and right vertical frames (new frame materials) 13, 14 are installed on the inner periphery of the existing upper frame (existing frame material) 2a, existing lower frame 2b, and left and right existing vertical frames (existing frame material) 2c that are attached to the skeleton B, thereby forming a new frame 10 for supporting a door panel 15 so that it can be opened and closed. The new upper frame 11, new lower frame 12, left and right new vertical frames 13, 14, door panel 15, and hinge 16 have the same configurations as those applied in the first embodiment.
[0027] 12 to 17 show the upper frame portion and the vertical frame portion of the fittings for renovation. Below, with reference to the drawings, we will mainly describe in detail the detailed configuration of the existing upper frame 2a and the existing vertical frame 2c, which are different from those in embodiment 1, and the mounting structure of the new upper frame 11 and the new vertical frames 13 and 14, and also explain the characteristic parts of the present invention.

[0028] The existing upper frame 2a has an existing upper main body 2aa, an existing upper door stop wall 2ab, and an existing upper mounting wall 2ac. The existing upper main body 2aa extends almost horizontally along the projection direction. The projection surface on the inner periphery of the existing upper main body 2aa has protrusions 2ad on both the indoor and outdoor portions. The existing upper door stop wall 2ab extends from the edge located on the indoor side of the existing upper main body 2aa toward the inner periphery. The portion of the existing upper door stop wall 2ab facing the outside has an existing upper sealing material mounting portion 2ae that protrudes toward the outside. The existing upper mounting wall 2ac extends from the edge located on the outdoor side of the existing upper main body 2aa toward the outer periphery. This existing upper frame 2a is attached to the body B by abutting the existing upper mounting wall portion 2ac against the surface of the body B facing outside, with the existing upper main body 2aa positioned on the inner periphery of the body B.
[0029] The existing vertical frames 2c are configured to be symmetrical on the left and right, each having an existing vertical main body 2ca, an existing vertical doorstop wall 2cb, and an existing vertical mounting wall 2cc. The existing vertical main body 2ca extends almost vertically along the projection direction. The projection surface on the inner periphery of the existing vertical main body 2ca has protrusions 2cd on both the indoor and outdoor portions. The existing vertical doorstop wall 2cb extends from the edge located on the indoor side of the existing vertical main body 2ca toward the inner periphery. The portion of the existing vertical doorstop wall 2cb facing the outside has an existing vertical seal material mounting portion 2ce that protrudes toward the outside. The existing vertical mounting wall 2cc extends from the edge located on the outdoor side of the existing vertical main body 2ca toward the outer periphery. This existing vertical frame 2c is attached to the main body B by abutting the existing vertical mounting wall portion 2cc against the surface of the main body B facing outside, with the existing vertical main body 2ca positioned on the inner periphery of the main body B.
[0030] The new upper frame 11, which is to be used to repair the existing upper frame 2a, has a metal frame portion 11A and a resin frame portion 11B, as in embodiment 1. The metal frame portion 11A is provided with a new upper outer frame body 11a, a new upper locking piece 11b, and a new upper outer hook portion 11c, while the resin frame portion 11B is provided with a new upper inner frame body 11d, a new upper door stop wall portion 11e, a new upper seal material mounting portion 11f, a storage portion forming wall 11g, a storage portion 11h, a new upper engaging claw portion 11i, and a new upper inner hook portion 11j. Also as in embodiment 1, upper frame fixing brackets (fixing brackets) 11C are attached to multiple locations on the outer periphery of the new upper frame 11.
[0031] The new vertical frames 13, 14, which are to be used to repair the existing vertical frame 2c, are configured to be symmetrical on the left and right. The metal frame portions 13A, 14A are provided with new outer vertical frame bodies 13a, 14a, new vertical locking pieces 13b, 14b, new outer vertical hook portions 13c, 14c, and new outer vertical seal material mounting portions 13d, 14d, while the plastic frame portions 13B, 14B are provided with new inner vertical frame bodies 13e, 14e, new vertical door stop walls 13f, 14f, new seal material mounting portions 13g, 14g, new inner vertical hollow portions 13h, 14h, new vertical engaging claw portions 13i, 14i, and new inner vertical hook portions 13j, 14j. Furthermore, vertical frame fixing brackets (fixing brackets) 13C, 14C are attached to multiple locations on the outer periphery of the newly installed vertical frames 13, 14.
[0032] The above-mentioned newly installed upper frame 11 is attached to the main body B by screwing an inner screw (inner fixing device) S6 into the main body B via the upper mounting piece portion 11Cb protruding toward the interior side of the upper frame fixing bracket 11C, and by screwing an outer screw (outer fixing device) S14 into the main body B via the resin frame portion 11B, the upper fixing piece portion 11Ca of the upper frame fixing bracket 11C, and the existing upper frame 2a. The newly installed vertical frames 13, 14 are attached to the main body B by screwing an internal screw S6 into the main body B via the vertical mounting piece portions 13Cb, 14Cb protruding toward the interior side of the vertical frame fixing brackets 13C, 14C, and by screwing an external screw (external fixing device) S15 into the main body B via the resin frame portions 13B, 14B, the vertical fixing piece portions 13Ca, 14Ca of the vertical frame fixing brackets 13C, 14C, and the existing vertical frame 2c.
[0033] More specifically, for the new upper frame 11, an upper inner spacer (inner spacer) D1 is installed on the existing inner frame H, which is attached to the interior side of the existing upper door stop wall 2ab of the existing upper frame 2a, and an upper frame reinforcement (frame reinforcement) 20 and an upper outer spacer D2 are installed on the inner periphery of the existing upper body 2aa. The upper frame reinforcement 20 is a flat plate made of metal such as steel or aluminum alloy, and is attached to the upper frame fixing bracket 11C by threading screws S7. As can be seen from the figure, the dimension of the upper frame reinforcement 20 along the projection direction is set to be approximately the same as the upper fixing piece 11Ca of the upper frame fixing bracket 11C. From the above-mentioned state, with the upper fixing piece portion 11Ca of the upper frame fixing bracket 11C abutting against the upper outer spacer D2, an inner screw S6 is screwed into the main body B via the upper mounting piece portion 11Cb, the upper inner spacer D1, and the existing inner frame H, and an outer screw S14 is screwed into the main body B via the resin frame portion 11B, the upper fixing piece portion 11Ca, the upper frame reinforcement material 20, and the existing upper frame 2a, and further an outer screw (external fixing device) S8 is screwed into the upper frame reinforcement material 20 via the metal frame portion 11A and the upper fixing piece portion 11Ca, thereby attaching the new upper frame 11 to the inner side of the existing upper frame 2a.
[0034] Similarly, for the new left vertical frame 13, which will serve as the hanging point, a vertical inner spacer (inner spacer) D3 is installed in the existing inner frame H, which is attached to the interior side of the existing vertical door stop wall 2cb of the existing vertical frame 2c, and a vertical frame reinforcement (frame reinforcement) 21 and a vertical outer spacer D4 are installed on the inner periphery of the existing vertical body 2ca. The vertical frame reinforcement 21 is a flat plate made of metal such as steel or aluminum alloy, and is attached to the existing vertical frame 2c in a position corresponding to the vertical frame fixing bracket 13C by screwing in the vertical frame reinforcement 21 with a screw S9. As is clear from the figure, the dimension of the vertical frame reinforcement 21 along the projection direction is set to be approximately the same as the vertical fixing piece 13Ca of the vertical frame fixing bracket 13C. From the above-mentioned state, with the vertical fixing piece portion 13Ca abutting the vertical outer spacer D4, an inner screw (inner fixing device) S10 is screwed into the main body B via the vertical mounting piece portion 13Cb, the vertical inner spacer D3 and the existing inner frame H, and an outer screw S15 is screwed into the main body B via the resin frame portion 13B, the vertical fixing piece portion 13Ca, the vertical frame reinforcement material 21 and the existing vertical frame 2c, and further an outer screw (outer fixing device) S11 is screwed into the vertical frame reinforcement material 21 via the metal frame portion 13A and the vertical fixing piece portion 13Ca, thereby attaching the new left vertical frame 13 to the inner side of the existing vertical frame 2c.
[0035] The new right vertical frame 14, which is located on the door-end side, may be attached in the same manner as the new left vertical frame 13. However, in the second embodiment, the vertical frame reinforcement 21 is omitted and the new right vertical frame 14 is attached to the inner periphery of the existing vertical frame 2c. Specifically, a vertical inner spacer D3 is first installed on the existing inner frame H, which is attached to the interior side of the existing vertical doorstop wall 2cb of the existing vertical frame 2c, and a vertical outer spacer D4 is installed on the inner periphery of the existing vertical body 2ca. Then, with the vertical frame fixing bracket 13C abutting the vertical outer spacer D4, the inner screw S10 is screwed into the frame B via the vertical mounting piece 14Cb and the vertical inner spacer D3. Furthermore, the outer screw S15 is screwed into the frame B via the resin frame 14B, the vertical fixing piece 14Ca, the vertical frame reinforcement 21, and the existing vertical frame 2c, thereby attaching the new right vertical frame 14 to the inner periphery of the existing vertical frame 2c.
[0036] As in the first embodiment, the new sill 12 is attached to the existing sill 2b by threading screws S12 while positioned on the inner periphery of the existing sill 2b. A new door can be constructed on the inner periphery of the existing sill 2b by supporting a door panel 15 so that it can be opened and closed on the new sill 10 constructed as described above. New outer frames F are provided between the exterior wall E and the new upper frame 11, and between the exterior wall E and the new vertical frames 13 and 14, respectively, to cover the existing upper frame 2a and the existing vertical frames 2c. The upper frame fixing bracket 11C and upper inner spacer D1, and the vertical frame fixing brackets 13C and 14C and vertical inner spacer D3, which protrude into the interior of the room, are each covered by a new inner frame G. The door closer 30 installed between the newly installed upper frame 11 and the door panel 15 has the closer body 31 attached to the interior surface of the door panel 15, and the tip of the arm 32 attached to the upper frame fixing bracket 11C via an arm reinforcement member 33.
[0037] In the renovation fitting configured as described above, the new upper frame 11 is attached to the skeleton B with inner screws S6 via upper mounting piece 11Cb that protrudes toward the room side of the upper frame fixing bracket 11C attached to the new upper frame 11. Furthermore, the metal frame portion 11A that faces the outside of the room is attached to the upper frame reinforcement 20 together with upper fixing piece 11Ca with outer screws S8, and the resin frame portion 11B that faces the inside of the room is attached to the skeleton B together with upper fixing piece 11Ca and upper reinforcement 20 with outer screws S14. Similarly, the new left vertical frame 13 is attached to the skeleton B with inner screws S10 via vertical mounting piece 13Cb that protrudes toward the room side of the vertical frame fixing bracket 13C attached to the new left vertical frame 13. Furthermore, the metal frame portion 13A on the exterior side is attached to the vertical frame reinforcement 21 together with the vertical fixing piece 13Ca by the external screw S11, and the resin frame portion 13B on the interior side is attached to the frame B together with the vertical fixing piece 13Ca and the vertical frame reinforcement 21 by the external screw S15. That is, the attachment strength of the new upper frame 11 and the new left vertical frame 13 to the frame B is improved by the upper frame fixing bracket 11C, the vertical frame fixing bracket 13C, the upper frame reinforcement 20, the vertical frame reinforcement 21, and the external screws S14 and S15. Therefore, even if an external force is applied to the new upper frame 11 or the new left vertical frame 13 due to the opening and closing of the door panel 15, it is possible to prevent deformation of each. Furthermore, the arm 32 of the door closer 30 has its tip attached to the upper frame fixing bracket 11C via the arm reinforcement 33 by the screw S13. Therefore, no external force is applied to the new upper frame 11 via the arm 32 when the door panel 15 is opened or closed or the door closer 30 is operated, and there is no risk of the new upper frame 11 being deformed.
[0038] In the second embodiment described above, the existing frame members are provided with frame reinforcement members, and screws are threaded into the frame reinforcement members via fixing brackets, which further improves the mounting strength of the new frame members, but the provision of frame reinforcement members is not necessarily required. Furthermore, although the outer screws S14 and S15 are provided so as to reach the frame body B, it is sufficient for the outer screws S14 and S15 to be threaded into the existing upper frame 2a and the existing vertical frame 2c.
[0039] In addition, while the above-described embodiments illustrate doors used at the entrance of buildings as renovation fixtures, the present invention can also be applied to other fixtures, such as sliding doors. While the new frame members constituting the new frame body are illustrated as having metal and resin frame members, the present invention is not limited to this. The new frame members may be integrally molded from metal or resin. Furthermore, the fixing brackets may simply be flat. In this case, it is preferable to perform pre-processing, such as removing the existing doorstop wall portion provided on the existing frame member.
