Description

[Technical Field]

[0001] The present invention relates to a fitting, and more particularly to a fitting in which a door body is supported by a frame body by a hinge so as to be able to be opened and closed. [Background technology]

[0002] BACKGROUND ART In fittings such as doors, a hinge is provided between a vertical frame of a frame and a door panel, and the door panel can be opened and closed relative to the frame (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2022-29689 Summary of the Invention [Problem to be solved by the invention]

[0004] Recently, door panels incorporating insulating material have been used to improve thermal insulation. However, these door panels tend to be thicker and heavier, raising concerns about the strength of the vertical frame where the hinges are installed. In particular, door panels designed with thermal insulation in mind often use vertical frames made of metal on the exterior side and resin on the interior side. This makes it difficult to ensure a large dimension along the projected direction of the metal frame, exacerbating the aforementioned problems. Furthermore, even in renovated door frames, the new vertical frame often protrudes further outward than the existing vertical frame, making it important to prevent strength issues.

[0005] In view of the above circumstances, the present invention aims to provide a fitting that can prevent strength problems with the vertical frame even when the weight of the door body increases. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the building fixture of the present invention is a building fixture comprising a frame body having vertical and horizontal frames, and a door body that is supported on the frame body so as to be able to open and close by a hinge provided between the frame body, wherein the hinge comprises a door-side hinge portion attached to the door body and a frame-side hinge portion attached to the frame body, and the frame-side hinge portion, the vertical frames and the horizontal frames are provided with connectors to connect them to each other. [Effects of the Invention]

[0007] According to the present invention, the frame-side hinge portion that supports the door body is connected to the vertical and horizontal frames by a connector, so that the weight of the door body can be supported by the vertical and horizontal frames, and therefore there is no risk of strength problems with the vertical frames even if the weight of the door body increases.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Preferred embodiments of the fittings according to the present invention will be described in detail below with reference to the accompanying drawings. Note that, for convenience, the terms "invisible direction" and "visible direction" will be used below. The "invisible direction" is the direction along the depth of the fittings, as indicated by arrow A in the drawings. A surface along the invisible direction will be referred to as a "visible face." The "visible direction" is the direction perpendicular to the invisible direction in the case of an object that extends horizontally, such as a top frame. In the case of an object that extends vertically, such as a vertical frame, the horizontal direction perpendicular to the invisible direction is referred to as the "visible direction." A surface along the invisible direction will be referred to as a "visible face."

[0010] 1 to 5 show a fixture according to an embodiment of the present invention. The fixture 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 1 in place. That is, in this entrance door, a new upper frame (horizontal frame) 11, a lower frame (horizontal frame) 12, and left and right vertical frames 13, 14 for renovation 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 10 for supporting a new door panel (door body) 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 arranged side by side in the forward direction. The metal frame sections 11A, 13A, 14A and the resin frame sections 11B, 13B, 14B are each extruded shapes 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 bridge member 12C connects the interior frame section 12A and the exterior frame section 12B. 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. In this embodiment, when viewed from the inside of the room, the vertical frame located on the left side (hereinafter referred to as left vertical frame 13) serves as the hanging point, and the vertical frame located on the right side serves as the door edge, with hinge 40 provided between door panel 15 and the frame.

[0015] As shown in Figures 2 and 6, the new lower frame 12, which is intended to renovate the existing lower frame 1b, is composed of a new lower body 12a, a new lower outer sight wall 12b, a new lower door stop wall 12c, a new lower inner sight wall 12d, and a new lower inner sight wall 12e. The new lower body 12a is flat and extends in the sight direction. As described above, the new lower frame 12 has an indoor frame 12A, an outdoor frame 12B, and a bridge member 12C. The new lower body 12a is composed of the body component 12A1 of the indoor frame 12A, the body component 12B1 of the outdoor frame 12B, and the bridge member 12C. The inner surface of the new lower body 12a is configured to be approximately flat along the horizontal direction. The outer peripheral portion of the new lower main body 12a has lower frame screw holes 12f provided in the portion closest to the exterior and on both sides of the bridge material 12C. The new lower outer sight wall 12b extends in the sight direction from the exterior edge of the new lower main body 12a toward the exterior. The new lower door stop wall 12c extends in the sight direction from the interior edge of the new lower main body 12a toward the interior. The inner peripheral edge of the new lower door stop wall 12c facing the outside is provided with a sealant attachment portion 12g for attaching the sealant C1. The new lower inner sight wall 12d extends in the sight direction from the interior edge of the new lower door stop wall 12c. The new lower inner sight wall 12e extends in the sight direction from the interior edge of the new lower inner sight wall 12d.

[0016] This new sill 12 is attached to the inner periphery of the existing sill 1b with the attachment 16 attached to the new sill 12 and the frame support member 17 attached to the existing sill 1b in advance. That is, the new sill 12 is attached to the inner periphery of the existing sill 1b by screwing the screw S1 into the existing sill body 1ba via the new sill inner projection wall portion 12d, and by screwing the screw S2 into the portion spanning the frame support member 17, lower spacer D1, and entrance porch E via the attachment 16 and heat insulating sheet 18.

[0017] As shown in Figures 2 and 7, the metal frame portion 11A of the new upper frame 11, which is the target of repairing the existing upper frame 1a, has a new upper outer frame body 11a with a cylindrical cross section that is approximately rectangular. 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. Upper frame screw holes 11d are provided in the inner periphery of the cylindrical interior of the new upper outer frame body 11a, in the portions closest to the outdoor side and the indoor side. The plastic frame portion 11B of the new upper frame 11 has a new upper inner frame body 11e with a cylindrical cross section that is approximately rectangular. The dimensions of the new upper inner frame body 11e along the front-facing direction are smaller than those of the new upper outer frame body 11a, but the dimensions along the front-facing direction are approximately equal to those of the new upper outer frame body 11a. A new upper door stop wall 11f is provided at the corner of the new upper inner frame body 11e, located on the interior side of the room. The new upper door stop wall 11f protrudes toward the interior from the new upper inner frame body 11e and has a new upper sealant attachment portion 11g for attaching the seal member C2 on the portion facing the exterior. A storage section-constituting wall 11h is provided at the corner of the new upper inner frame body 11e, located on the interior side of the room, on the exterior side. The storage section-constituting wall 11h extends toward the interior and then bends toward the interior. The corner of the new upper inner frame body 11e, located on the exterior side of the room, is provided with a new upper engagement claw portion 11i on the outer periphery and a new upper inner hook portion 11j on the inner periphery. The new upper engaging claw portion 11i protrudes toward the outer periphery and is provided to correspond to the new upper locking piece 11b of the metal frame portion 11A. The new upper inner hook portion 11j extends toward the outside of the room and then bends toward the inner periphery and is provided to correspond to the new upper outer hook portion 11c of the metal frame portion 11A.

[0018] 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. They are further integrated by threading a frame connecting screw (frame connecting tool) S3 into the new upper outer frame body 11a via the new upper inner frame body 11e. Furthermore, upper frame fixing brackets 11C are attached at 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 S4 while abutting the outer peripheral surfaces of the metal frame 11A and the resin frame 11B. The upper fixing piece 11Ca is attached to the resin frame 11B with a screw S5. The upper mounting piece 11Cb extends from the edge of the upper fixing piece 11Ca located on the interior side of the room, along the interior surface of the new upper frame 11, and then protrudes toward the room from a position approximately halfway along the interior of the new upper frame 11.

[0019] As shown in Figures 3, 4, and 8, the metal frame portion 13A of the new left vertical frame 13, which is intended to renovate the existing vertical frame 1c, has a new vertical outer frame body 13a with a generally rectangular tubular cross section. A new vertical locking piece 13b extends toward the room at the corner located on the interior side of the outer periphery of the new vertical outer frame body 13a. A new vertical outer hook portion 13c and a new vertical outer sealant attachment portion 13d are provided at the corner located on the interior side of the inner periphery of the new vertical outer frame body 13a. The new vertical outer hook portion 13c extends toward the room and then bends toward the outer periphery. The new vertical outer sealant attachment portion 13d is used to attach the vertical outer seal member C3 and protrudes toward the inner periphery. The plastic frame portion 13B of the new left vertical frame 13 has a new vertical inner frame body 13e with a generally rectangular tubular cross section. The dimensions of the new vertical inner frame body 13e along the front-facing direction are smaller than those of the new vertical outer frame body 13a, but the dimensions along the front-facing direction are approximately the same as those of the new vertical outer frame body 13a. A new vertical door stop wall 13f is provided at the corner on the inner periphery of the new vertical inner frame body 13e, which is located on the interior side of the room. The new vertical door stop wall 13f protrudes toward the interior from the new vertical inner frame body 13e and has a new vertical seal material mounting portion 13g for mounting the seal member C4 on the portion facing the exterior. A new vertical inner hollow portion 13h is provided in the interior side of the new vertical inner frame body 13e. The dimensions of the new vertical inner hollow portion 13h along the front-facing direction are approximately the same as those of the new vertical inner frame body 13e, but the dimensions along the front-facing direction are smaller. At the corners of the new vertical inner frame body 13e located on the exterior side of the room, new vertical engaging claws 13i are provided on the outer periphery, and new vertical inner hooks 13j are provided on the inner periphery. The new vertical engaging claws 13i protrude toward the outer periphery and are provided to correspond to the new vertical locking pieces 13b of the metal frame part 13A. The new vertical inner hooks 13j extend toward the exterior and then bend toward the inner periphery, and are provided to correspond to the new vertical outer hooks 13c of the metal frame part 13A.

[0020] The metal frame portion 13A and resin frame portion 13B of the new left vertical frame 13 are interconnected by engaging the new vertical outer hook portion 13c with the new vertical inner hook portion 13j and by engaging the new vertical locking piece 13b with the new vertical locking claw portion 13i. They are then integrated by threading a frame connecting screw S3 into the new vertical outer frame body 13a via the new vertical inner frame body 13e. The dimensions of the new left vertical frame 13, which integrates the metal frame portion 13A and resin frame portion 13B, along the projected direction are larger than the dimensions of the portion of the existing vertical body 1ca that is located outside the existing vertical seal material mounting portion 1ce. Furthermore, vertical frame fixing brackets 13C are attached at multiple locations along the length of the outer periphery of the new left vertical frame 13. The vertical frame fixing bracket 13C is molded from steel or aluminum alloy metal and includes a vertical fixing piece 13Ca and a vertical mounting piece 13Cb. The vertical fixing piece 13Ca is a flat plate extending from the metal frame 13A to the resin frame 13B. It is attached to the new left vertical frame 13 by screwing a screw S7 into each of the vertical fixing piece 13Ca while abutting the outer peripheral surfaces of the metal frame 13A and the resin frame 13B. The vertical mounting piece 13Cb extends from the interior edge of the vertical fixing piece 13Ca along the interior-facing surface of the new left vertical frame 13 and then protrudes toward the room from a corner located on the inner periphery of the new left vertical frame 13. The dimension of the new left vertical frame 13 along the projection direction is approximately equal to the dimension of the new upper frame 11 along the projection direction.

[0021] As shown in Figures 2 and 7, the above-mentioned new upper frame 11 is attached to the frame B by threading an internal screw S8 into the frame B via the upper mounting piece 11Cb protruding toward the interior of the frame fixing bracket 11C. More specifically, for the new upper frame 11, an upper inner spacer D2 protruding inward from the existing upper door stop wall 1ab is previously disposed in the existing upper frame 1a at a portion that is on the interior side of the room relative to the existing upper door stop wall 1ab, and an upper frame reinforcement 20 and an upper outer spacer D3 are disposed on the surface that is expected to be the inner periphery of the existing upper main body 1aa. The upper frame reinforcement 20 is a flat plate formed from a metal such as steel or aluminum alloy, and is attached to a position corresponding to the upper frame fixing bracket 11C by threading a screw S9. 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 D3, and the inner screw S8 is screwed into the frame B via the upper mounting piece portion 11Cb and the upper inner spacer D2, and the outer screw S10 is screwed into the upper frame reinforcement material 20 via the metal frame portion 11A of the new upper frame 11 and the upper fixing piece portion 11Ca, thereby attaching the new upper frame 11 to the inner side of the existing upper frame 1a. An outer upper frame G1 is provided between the metal frame portion 11A of the new upper frame 11 and the exterior wall panel F so as to cover and conceal the existing upper frame 1a.

[0022] Similarly, as shown in Figures 3, 4, and 8, the new left vertical frame 13 is attached to the frame B by threading an inner screw S11 into the frame B via the vertical mounting piece 13Cb that protrudes toward the room side of the vertical frame fixing bracket 13C. More specifically, for the new left vertical frame 13, a vertical inner spacer D4 that protrudes inward from the existing vertical doorstop wall 1cb is previously disposed in the existing vertical frame 1c on the room side of the existing vertical doorstop wall 1cb, and a vertical frame reinforcement 21 and a vertical outer spacer D5 are disposed on the surface that will become the inner periphery of the existing vertical main body 1ca. The vertical frame reinforcement 21 is a flat plate formed from a metal such as steel or aluminum alloy, and is attached to the position corresponding to the vertical frame fixing bracket 13C by threading a screw S12. As can be seen 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-described state, the vertical fixing piece 13Ca is abutted against the vertical outer spacer D5, and the internal screw S11 is threaded into the frame B via the vertical mounting piece 13Cb and the vertical inner spacer D4. Furthermore, the external screw S13 is threaded into the vertical frame reinforcement 21 via the metal frame portion 13A of the new left vertical frame 13 and the vertical fixing piece 13Ca, thereby attaching the new left vertical frame 13 to the inner periphery of the existing vertical frame 1c. As can be seen from the figure, the new left vertical frame 13 protrudes farther outside the room than the existing vertical frame 1c. An external vertical frame G2 is provided on the metal frame portion 13A of the new left vertical frame 13 to conceal the existing vertical frame 1c.

[0023] 9 to 14, the new left vertical frame 13 is connected to the new upper frame 11 by threading connecting screws (connectors) S14 into the upper frame screw holes 11d of the metal frame portion 11A of the new upper frame 11 via the metal frame portion 13A, and is connected to the new lower frame 12 by threading connecting screws (connectors) S14 into the lower frame screw holes 12f of the outdoor frame portion 12B of the new lower frame 12 via the metal frame portion 13A. Although not shown in the figures, the new right vertical frame 14 is also attached to the inner periphery of the existing vertical frame 1c, like the new left vertical frame 13, and both upper and lower ends are connected to the new upper frame 11 and the new lower frame 12 by connecting screws S14. Like the new left vertical frame 13, the metal frame portion 14A of the new right vertical frame 14 has an outer vertical frame G2.

[0024] As is clear from the figure, frame-side hinge portions 40A are provided at both the upper and lower ends of the new left vertical frame 13. The frame-side hinge portions 40A are linked to door-side hinge portions 40B provided at both upper and lower corners of the door panel 15 on the hanging side, thereby forming hinges (pivot hinges) 40 that support the door panel 15 so that it can be opened and closed relative to the new frame body 10 (see FIG. 5). In this embodiment, the frame-side hinge portion 40A is configured to include a hinge body 41 and a reinforcing member 42 formed from a metal such as steel. The hinge body 41 has a protruding portion 41a that links to the door-side hinge portion 40B. In the illustrated example, the hinge body 41 is configured so that its dimension along the projection direction is larger than that of the metal frame portion 13A of the new left vertical frame 13. The reinforcing member 42 is formed by integrally molding a hinge reinforcing plate portion 42a, which is interposed between the hinge body 41 and the metal frame portion 13A of the new left vertical frame 13, and a resin reinforcing plate portion 42b, which extends in the viewing direction from the edge of the hinge reinforcing plate portion 42a located on the interior side of the room, and is configured with dimensions that can be housed inside the tube of the metal frame portion 13A. The longitudinal dimension of the reinforcing member 42 is larger than that of the hinge body 41.

[0025] The frame side hinge portion 40A having the above-described configuration is connected to the metal frame portion 13A of the new left vertical frame 13 and the outdoor frame portion 12B of the new lower frame 12 via the reinforcing member 42 by overlapping the hinge reinforcing plate portion 42a with the inner wall portion 13a1 located on the inner side of the metal frame portion 13A before connecting the new left vertical frame 13 to the new lower frame 12, and then screwing the connecting screw S14 into the lower frame screw hole 12f of the new lower frame 12 through the metal frame portion 13A and the hinge reinforcing plate portion 42a. Similarly, the other frame side hinge portion 40A is connected to the metal frame portion 13A of the new left vertical frame 13 and the metal frame portion 11A of the new upper frame 11 via the reinforcing member 42 by overlapping the hinge reinforcing plate portion 42a with the inner wall portion 13a1 located on the inner side of the metal frame portion 13A before connecting the new left vertical frame 13 to the new upper frame 11, and then screwing a connecting screw S14 into the new upper frame 11 via the metal frame portion 13A and the hinge reinforcing plate portion 42a. Furthermore, before the metal frame portion 13A and the resin frame portion 13B are connected, the hinge reinforcing plate portion 42a of the frame side hinge portion 40A is connected to the metal frame portion 13A and the resin frame portion 13B via the reinforcing member 42 by overlapping the resin reinforcing plate portion 42b on the inner wall portion 13a2 located on the indoor side of the metal frame portion 13A, and from this state, screwing the frame connecting screw S3 through the resin frame portion 13B and the metal frame portion 13A.

[0026] On the other hand, each hinge body 41 has its protruding portion 41a protruding outward through a notch 13k provided in the metal frame portion 13A of the new left vertical frame 13 and overlapping with the hinge reinforcing plate portion 42a, and from this state is connected to the metal frame portion 13A and the hinge reinforcing plate portion 42a by screwing an auxiliary connecting screw (auxiliary connector) S15 through the inner peripheral wall portion 13a1 of the metal frame portion 13A and the hinge reinforcing plate portion 42a. When attaching the frame-side hinge portion 40A to the new frame body 10, in order to prevent interference with the outer vertical frame G2 provided on the new left vertical frame 13 and the outer upper frame G1 provided on the new upper frame 11 when the door panel 15 is opened, the protruding dimension from the visible surface facing the exterior of the new left vertical frame 13 is set to satisfy all of the following conditions: (1) The distance d1 from the visible surface of the newly installed left vertical frame 13 to the corner located on the inner periphery of the outer vertical frame G2 is smaller than the distance d2 to the hinge axis HC between the frame side hinge portion 40A and the door side hinge portion 40B. (2) The distance d2 from the visible surface of the newly installed left vertical frame 13 to the hinge axis HC plus the distance d3 from the exterior surface of the door panel 15 positioned in the closed position to the hinge axis HC is greater than the distance d4 from the visible surface of the newly installed left vertical frame 13 to the most protruding position of the outer vertical frame G2. (3) The distance d2 to the hinge axis HC is greater than the distance d4 from the visible surface of the newly installed left vertical frame 13 to the most protruding position of the outer upper frame G1 provided on the newly installed upper frame 11.

[0027] In the fittings configured as described above, the frame-side hinge portion 40A provided above the new left vertical frame 13 is connected to the new left vertical frame 13 and the new upper frame 11, and the frame-side hinge portion 40A provided below is connected to the new left vertical frame 13 and the new lower frame 12. Therefore, when the door panel 15 is rotatably supported on the new frame body 10 via the door-side hinge portion 40B, the weight of the door panel 15 applied to the new frame body 10 via the door-side hinge portion 40B and the frame-side hinge portion 40A is supported not only by the new left vertical frame 13 but also by the new upper frame 11 and the new lower frame 12. This eliminates the risk of strength problems such as deformation of the new frame body 10, even if a heavy door panel 15 with a thick plate containing insulation is applied to the new frame body 10 for renovation, which is provided to protrude outside the existing frame body 1.

[0028] While the above-described embodiment illustrates a fixture for renovation, the present invention does not necessarily have to be a fixture for renovation. Furthermore, while the new vertical frame constituting the new frame body is illustrated as having a metal frame portion and a resin frame portion, the present invention may also be formed solely from metal. Furthermore, while a hinge is provided between the vertical frame located on the left side as viewed from the interior side and the door panel, a hinge may also be provided between the vertical frame on the opposite side. Furthermore, although a connector is provided for each of the multiple frame-side hinge portions, it is sufficient that a connector is provided for at least one frame-side hinge portion. For example, in the embodiment, a connecting screw S14 may be provided only for the frame-side hinge portion located below the left vertical frame. Therefore, the number of hinges does not necessarily have to be two, and may be three or more. The shape of the hinge does not necessarily have to be a pivot hinge; a hinge-type hinge can also be similarly applied. Furthermore, although the frame-side hinge portion is exemplified as one in which the hinge body and the reinforcing member are molded separately, it is also possible to apply a hinge in which the hinge body and the reinforcing member are molded integrally.

[0029] As described above, the building fixture of the present invention is a building fixture comprising a frame body having vertical and horizontal frames, and a door body that is supported on the frame body so as to be able to open and close by a hinge provided between the frame body, and the hinge comprises a door-side hinge portion attached to the door body and a frame-side hinge portion attached to the frame body, and the frame-side hinge portion, the vertical frames, and the horizontal frames are provided with connectors to connect them to each other. According to this invention, the frame-side hinge portion that supports the door body is connected to the vertical and horizontal frames by a connector, so that the weight of the door body can be supported by the vertical and horizontal frames, and therefore there is no risk of strength problems for the vertical frames even if the weight of the door body increases.

[0030] The present invention is also characterized in that, in the above-mentioned building fixture, the frame side hinge portion comprises a hinge body protruding from the vertical frame and a reinforcing member, and the hinge body, the reinforcing member and the vertical frame are provided with auxiliary connectors to connect them to each other, and the reinforcing member, the vertical frame and the horizontal frame are provided with connectors to connect them to each other. According to this invention, it is possible to use the conventional frame-side hinge portion as the hinge body, which is advantageous in terms of versatility.

[0031] The present invention is also characterized in that, in the above-mentioned building fixture, the vertical frame has a metal frame portion molded from metal and a resin frame portion molded from resin, and the connector is provided on the metal frame portion. According to this invention, even in a fixture having a vertical frame with a metal frame portion and a resin frame portion, it is possible to support a door body without causing strength problems.

[0032] The present invention is also characterized in that, in the above-mentioned building fixture, the vertical frame has a metal frame portion molded from metal and a resin frame portion molded from resin, and the metal frame portion, the resin frame portion and the frame side hinge portion are provided with frame connectors to connect them to each other. According to this invention, the resin frame portion, the metal frame portion, and the frame-side hinge portion are connected by the frame connector, so that the connection strength between the resin frame portion and the metal frame portion can be increased.

[0033] The present invention is also characterized in that, in the above-mentioned building fixture, the vertical frame is provided on the inner periphery of an existing vertical frame attached to the main body and supports the door body rotatably. According to this invention, even in the case of renovation fittings, it is possible to support the door body without causing strength problems.

[0034] The present invention is also characterized in that, in the above-mentioned building fixture, the vertical frame is provided on the inner periphery of the existing vertical frame, protruding further outside the room than the existing vertical frame. According to this invention, it is possible to install vertical frames and door bodies with large dimensions in the projection direction, regardless of the dimensions of the existing vertical frames.
