Description

[Technical Field]

[0001] The present invention relates to a renovation fitting in which a new upper frame of a new frame body is provided on the inner periphery of an existing upper frame attached to a main body, and a new door panel is supported on the new frame body so that it can be opened and closed. [Background technology]

[0002] Some fixtures with door panels have a door closer installed between the door panel and the frame to control the open / closed state of the door panel. The door closer has a closer body attached to the door panel and an arm that connects the closer body and the frame, with the tip of the arm attached to the upper frame that makes up the frame (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-207723 Summary of the Invention [Problem to be solved by the invention]

[0004] When renovating a fixture, it is necessary to reposition the door closer arm. For example, in a renovation method in which a new upper frame of a new frame body is installed on the inner periphery of an existing upper frame attached to the frame, the arm is relocated to the new upper frame. However, it is more difficult to ensure the attachment strength to the frame for the new upper frame than for the existing upper frame, and there is a concern that the arm may be deformed by the weight of the new door panel when it is installed.

[0005] In view of the above-mentioned circumstances, the present invention aims to provide a renovation fitting that can install a door closer without causing deformation to the newly installed upper frame. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the renovation fitting of the present invention is a renovation fitting which comprises a new upper frame of a new frame body on the inner periphery of an existing upper frame attached to a main body, and a new door panel is supported on the new frame body so that it can be opened and closed, and is characterized in that a fixing bracket is attached to the outer periphery of the new upper frame so that it protrudes further inside the room than the new upper frame, the part of the fixing bracket that protrudes further inside the room than the new upper frame is attached to the main body by an internal fixing device, an arm reinforcement member is attached to the inner periphery of the fixing bracket, and the arm of the door closer which connects with the closer body attached to the new door panel is attached to the arm reinforcement member. [Effects of the Invention]

[0007] According to the present invention, the arm is attached to the main body via an arm reinforcement and a fixing bracket, so there is no risk of deformation of the newly installed upper frame even when the load of the newly installed door panel is applied via the arm.

[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 face." The prospect direction is the direction perpendicular to the prospect direction for items that extend horizontally, such as sill frames. For items that extend vertically, such as vertical frames, 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 face."

[0010] 1 to 3 show a renovation fitting according to an embodiment of the present invention. The renovation fitting illustrated here is a door used at the entrance of a building such as a detached house, and in particular, illustrates a renovation entrance door that is installed while leaving the existing frame body 1 in place. That is, in this entrance door, a new upper frame 11, a lower 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 a building frame B, thereby forming a frame body 10 for supporting a newly installed 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-side metal frame portion 11A, 13A, 14A molded from a metal such as an aluminum alloy, and an interior-side resin frame portion 11B, 13B, 14B molded from a resin, and are formed by connecting the metal frame portions 11A, 13A, 14A and the resin frame portions 11B, 13B, 14B to each other. The metal frames 11A, 13A, and 14A and the resin frames 11B, 13B, and 14B are each extruded sections with a uniform cross-sectional shape along their entire length. The new lower frame 12, on the other hand, has an interior frame 12A and an exterior frame 12B made of aluminum alloy or other metal, and a bridge member 12C made of insulating material. The interior frame 12A and the exterior frame 12B are connected via the bridge member 12C. The new door panel 15, not shown in the figure, is a flush panel, constructed by attaching surface materials to a framed frame on all four sides. Although not shown in the figure, in this embodiment, when viewed from inside the room, the vertical frame located on the left side (hereinafter referred to as the left vertical frame 13 for distinction) serves as the hanging point, and the vertical frame located on the right side (hereinafter referred to as the right vertical frame 14 for distinction) serves as the door edge, with a hinge 16 provided between the newly installed 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 resin frame portions 13B, 14B of these new vertical frames 13, 14 are interconnected by engaging the new vertical outer hook portions 13c, 14c with the new vertical inner hook portions 13j, 14j and by engaging the new vertical locking pieces 13b, 14b with the new vertical locking claw portions 13i, 14i. These are then integrated by threading screws S4 into the new vertical outer frame bodies 13a, 14a via the new vertical inner frame bodies 13e, 14e. Furthermore, vertical frame fixing brackets 13C, 14C are attached to the outer periphery of the new vertical frames 13, 14 at multiple locations along the length. The vertical frame fixing brackets 13C, 14C are molded from steel or aluminum alloy and have 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 parts 13A, 14A to the resin frame parts 13B, 14B, and are attached to the new vertical frames 13, 14 by screwing screws S5 into each of them while abutting against the outer peripheral surfaces of the metal frame parts 13A, 14A and the resin frame parts 13B, 14B. The vertical mounting pieces 13Cb, 14Cb extend from the interior-facing edge of the vertical fixing pieces 13Ca, 14Ca to the interior along the interior-facing surfaces of the new vertical frames 13, 14, and then protrude toward the room from the inner corners of the new vertical frames 13, 14. The dimension of the new vertical frames 13, 14 along the projection direction is approximately equal to the dimension 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 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 20 and an upper outer spacer D2 that are installed on the projected surface of the existing upper body 1aa, which will be the inner periphery 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 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 D3 is installed in the existing vertical frame 1c, protruding inward from the existing vertical door stop wall 1cb, on the interior side of the existing vertical door stop wall 1cb. A vertical 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, the inner screw S10 is screwed into the main body B via the vertical mounting piece portion 13Cb and the vertical inner spacer D3, and the outer screw 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 at the door end, may be attached in the same manner as the new left vertical frame 13. However, in this 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. Specifically, a vertical inner spacer D3 is first provided in the existing vertical frame 1c, protruding inward from the existing vertical doorstop wall 1cb on the interior side of the room relative to the existing vertical doorstop wall 1cb, and a vertical outer spacer D4 is provided 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 10 by supporting a new door panel 15 so that it can be opened and closed. 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, new outer frames F are provided 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 new door panel 15. The door closer 30 includes a closer body 31 attached to the interior surface of the new door panel 15, and an arm 32 connecting the closer body 31 and the new upper frame 11. In the illustrated example, 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 an attachment 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 mounting 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 new 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 mounting 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 new 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 above-described embodiment, the upper frame reinforcement 20 is provided on the existing upper frame 1a, and the external screw S8 is screwed into the upper frame reinforcement 20 via the upper frame fixing bracket 11C. However, the present invention is not limited to this, and the screw may be screwed into the existing upper frame via the fixing bracket. In this case, it is not necessarily necessary to provide the frame reinforcement on the existing upper frame.

[0026] 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 upper frame constituting the new frame body is illustrated as having a metal frame portion and a resin frame portion, the present invention is not limited to this, and the new upper frame may be integrally molded from metal or resin. Furthermore, the fixing bracket may simply be a flat plate. In this case, it is preferable to perform pre-processing, such as removing the existing door stop wall portion provided on the existing upper frame.

[0027] As described above, the renovation fittings of the present invention are fittings for renovation that include a new upper frame of a new frame body on the inner side of the existing upper frame attached to the main body, and a new door panel that is supported on the new frame body so that it can be opened and closed; a fixing bracket is attached to the outer side of the new upper frame so that it protrudes further inside the room than the new upper frame, and the part of the fixing bracket that protrudes further inside the room than the new upper frame is attached to the main body by an internal fixing device; an arm reinforcement member is attached to the inner side of the fixing bracket, and the arm of the door closer that connects it to the closer body attached to the new door panel is attached to the arm reinforcement member. According to this invention, the arm is attached to the main body via an arm reinforcement and a fixing bracket, so there is no risk of deformation of the newly installed upper frame even when the load of the newly installed door panel is applied via the arm.

[0028] The present invention is also characterized in that, in the above-mentioned renovation fittings, the newly installed upper frame has a resin frame portion on the indoor side and a metal frame portion on the outdoor side, the fixing brackets are attached to the resin frame portion and the metal frame portion, respectively, and the arm reinforcement material is accommodated in an accommodating portion provided in the resin frame portion. According to this invention, it is possible to prevent the arm reinforcement from being exposed to the outside, which is advantageous in terms of appearance quality.

[0029] The present invention is also characterized in that, in the above-mentioned renovation building fixture, a frame reinforcement material is attached to the inner peripheral portion of the existing upper frame, and the newly constructed upper frame is attached to the frame reinforcement material via the fixing bracket with an external fixing device. According to the present invention, it is possible to further improve the mounting strength of the door closer. [Explanation of symbols]
