[Technical field]

[0001] The present disclosure relates to retrofit fittings. [Background technology]

[0002] Conventionally, when renovating an opening in a building, a new frame is attached to the inner periphery of the existing frame attached to the opening.

[0003] For example, in the remodeled sash unit of Patent Document 1, the remodeled frame is attached to the existing frame via a base frame. A cover member is attached to the outside of the base frame. The cover member covers the space between the remodeled frame and the exterior wall where the opening is provided from the outside of the room. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2011-12405 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the dimensions and fit of the existing frame vary depending on the construction example. For this reason, depending on the construction example, inconveniences may occur such as the base frame being tilted or the dimensions of the cover member not fitting the opening. As such, the retrofit sash unit of Patent Document 1 has room for improvement in terms of versatility.

[0006] The present disclosure aims to provide highly versatile renovation fittings. [Means for solving the problem]

[0007] The renovation fixture of the present disclosure comprises an existing frame remaining in an opening of a building, a new frame that is attached so as to cover the inner side of the existing frame, a base material that is placed between the existing frame and the new frame, and an adjustment mechanism that can adjust the distance in the front direction between the base material and the existing frame, and the adjustment mechanism has an extension portion that is provided on the base material and extends in the front direction, a support member that extends in the front direction and is supported by the existing frame, and an insertion member that passes through the extension portion and the support member, and adjusts at least one of the position where the insertion member passes through the extension portion and the position where the insertion member passes through the support member, thereby adjusting the distance in the front direction between the base material and the existing frame.

[0009] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. As shown in Fig. 1 and Fig. 2, a remodeling fitting 1 of this embodiment is installed in an opening 101 of a building 100. The remodeling fitting 1 is formed by performing a remodeling process in which a new frame 6 is attached to an existing frame 3 that has already been installed. The opening shape of the opening 101 is approximately rectangular.

[0010] In this specification, "front view direction" refers to the direction in which the faces of the facing materials of the shoji screens 14, 15 of the remodeled fitting 1 placed in the opening 101 extend. "Outer front view direction" refers to the front view direction from the inner periphery toward the outer periphery of the opening 101. "Inner front view direction" refers to the front view direction from the outer periphery toward the inner periphery of the opening 101. "Front view surface" refers to the surface of the remodeled fitting 1 that extends in the front view direction. "Left-right direction" refers to the horizontal direction in the front view direction, and refers to the left-right direction when the remodeled fitting 1 is viewed from the inside of the room.

[0011] In this specification, the "prospect direction" refers to the thickness direction (i.e., the depth direction) of the surface material of the shoji screens 14 and 15. The "prospect direction" also refers to the indoor / outdoor direction. The "prospect surface" refers to the surface of the remodeling fixture 1 that extends in the indoor / outdoor direction.

[0012] As shown in Figs. 1 to 3, the remodeled fitting 1 has a frame 2, an existing frame 3, a base material 4, a new frame 6, a cover material 10, an angle 7, an angle cover material 8, a trim material 9, a pair of paper screens 14, 15, and a screen door 16. The remodeled fitting 1 is constructed by attaching the new frame 6 to the inner periphery of the existing frame 3 installed in an opening 101 of a building 100 via the base material 4. The remodeled fitting 1 is a sliding window. The paper screens 14, 15 and the screen door 16 are each slidably accommodated inside the new frame 6.

[0013] The frame 2 is a frame provided in the opening 101. The frame 2 is provided in a region of the opening 101 closer to the interior side of the room. The frame 2 is formed in a rectangular frame shape. The frame 2 is made of wooden boards. The frame 2 has a lower frame 2A, an upper frame 2B, and a pair of left and right vertical frames 2C.

[0014] The existing frame 3 is a frame body provided in the opening 101. The existing frame 3 is arranged on the exterior side of the frame 2. The existing frame 3 is formed in a rectangular frame shape. The existing frame 3 is composed of shaped materials made of aluminum, aluminum-resin composite, or resin. The existing frame 3 has an existing lower frame 3A, an existing upper frame 3B, and a pair of existing vertical frames 3C on the left and right.

[0015] The existing lower frame 3A is a long member extending in the left-right direction below the opening 101. The existing lower frame 3A has an L-shaped member 31A having an L-shaped cross section. The L-shaped member 31A is arranged at the end of the existing lower frame 3A on the indoor side. A portion of the L-shaped member 31A on the indoor side is placed on the upper surface of the lower frame 2A. The portion of the lower frame 2A on which the L-shaped member 31A is placed is cut out. The upper surfaces of the L-shaped member 31A and the lower frame 2A are flush with each other.

[0016] The existing upper frame 3B is a long member extending in the left-right direction above the opening 101. Like the existing lower frame 3A, the existing upper frame 3B has an L-shaped member 31B having an L-shaped cross section. The L-shaped member 31B is in contact with the upper frame 2B.

[0017] Each of the existing vertical frames 3C is a long member extending in the up-down direction at both left-right ends of the opening 101. Like the existing lower frame 3A, each of the existing vertical frames 3C has an L-shaped member 31C with an L-shaped cross section. Each of the L-shaped members 31C is in contact with each of the vertical picture frames 2C.

[0018] The base material 4 is disposed between the existing frame 3 and the new frame 6, and is a member for fixing the new frame 6 to the existing frame 3. The base material 4 is made of an aluminum shaped material. The base material 4 has a lower frame base material 4A, an upper frame base material 4B, and a pair of left and right vertical frame base materials 4C.

[0019] The lower frame base material 4A is fixed to the existing lower frame 3A. The end of the lower frame base material 4A on the indoor side extends to a position where it overlaps with the lower frame 2A and the L-shaped member 31A when viewed in the vertical direction.

[0020] The upper frame base material 4B is fixed to the existing upper frame 3B. The indoor end of the upper frame base material 4B extends to a position where it overlaps with the upper frame 2B and the L-shaped member 31B when viewed in the vertical direction.

[0021] Each vertical frame base material 4C is fixed to each existing vertical frame 3C. The indoor end of each vertical frame base material 4C extends to a position where it overlaps with each vertical frame 2C and each L-shaped member 31C when viewed in the left-right direction.

[0022] The new frame 6 is fixed to the inner periphery of the existing frame 3 via the base material 4. Between the base material 4 and the new frame 6, intermediate members 64 such as spacers are appropriately arranged. The new frame 6 is formed in a rectangular frame shape. The new frame 6 is made of aluminum shaped material. The new frame 6 has a new lower frame 6A, a new upper frame 6B, and a pair of new vertical frames 6C on the left and right.

[0023] The new lower frame 6A is a long member extending in the left-right direction below the opening 101. The new lower frame 6A is divided into two in the projection direction. The new lower frame 6A has an exterior frame portion 61A, an interior frame portion 62A arranged on the indoor side of the exterior frame portion 61A, and a bridge material 63A arranged between the exterior frame portion 61A and the interior frame portion 62A.

[0024] The exterior frame portion 61A and the interior frame portion 62A are each fixed to the lower frame base material 4A. An intermediate member 64A is disposed between the lower frame base material 4A and the newly installed lower frame 6A. The interior end of the interior frame portion 62A extends to a position where it overlaps with the lower frame 2A, the L-shaped member 31A, and the lower frame base material 4A when viewed in the vertical direction.

[0025] The bridge material 63A connects the outdoor frame portion 61A and the indoor frame portion 62A. The bridge material 63A is made of a material having heat insulating properties, and more specifically, is made of a resin having heat insulating properties. The bridge material 63A is formed hollow. This makes it possible to suppress heat transfer between the indoors and outdoors.

[0026] The new upper frame 6B is a long member extending in the left-right direction above the opening 101. The new upper frame 6B has a configuration roughly corresponding to that of the new lower frame 6A. The new upper frame 6B has an outdoor side frame portion 61B, an indoor side frame portion 62B arranged on the indoor side of the outdoor side frame portion 61B, and a bridge member 63B formed from a material having thermal insulation properties and connecting the outdoor side frame portion 61B and the indoor side frame portion 62B.

[0027] The exterior frame portion 61B and the interior frame portion 62B are each fixed to the upper frame base material 4B. An intermediate member 64B is disposed between the upper frame base material 4B and the newly installed upper frame 6B. The interior end of the interior frame portion 62B extends to a position where it overlaps with the upper frame 2B, the L-shaped member 31B, and the upper frame base material 4B when viewed in the vertical direction.

[0028] In addition, when there is no particular need to distinguish between them, the outdoor frame portion 61A and the outdoor frame portion 61B are collectively referred to as the "outdoor frame portion 61", the indoor frame portion 62A and the indoor frame portion 62B are collectively referred to as the "indoor frame portion 62", and the bridge material 63A and the bridge material 63B are collectively referred to as the "bridge material 63".

[0029] Each of the new vertical frames 6C is a long member extending vertically at both ends in the left-right direction of the opening 101. Unlike the new lower frame 6A and the new upper frame 6B, each of the new vertical frames 6C is not divided into two in the prospective direction. In this way, the new frame does not have to be divided into an exterior frame portion and an interior frame portion, and the exterior frame portion and the interior frame portion do not have to be connected by a bridge material.

[0030] Each of the new vertical frames 6C is fixed to a corresponding vertical frame base material 4C. An intermediate member 64C is disposed between each of the new vertical frames 6C and each of the vertical frame base materials 4C.

[0031] The cover material 10 is disposed on the outdoor side of the base material 4. The cover material 10 is fixed to the outdoor side end of the base material 4. The cover material 10 covers the base material 4 and the existing frame 3 from the outdoor side.

[0032] The cover material 10 has a lower frame cover material 10A fixed to the lower frame base material 4A, an upper frame cover material 10B fixed to the upper frame base material 4B, and vertical frame cover materials 10C fixed to each vertical frame base material 4C.

[0033] The angle 7 is attached to the end of the new frame 6 on the indoor side. The angle 7 is formed, for example, from resin. The angle 7 is formed, for example, in a ring shape. The angle 7 has a generally L-shape in cross section. Note that the angle 7 does not have to be formed in a ring shape, and may be formed, for example, by framing a long member into a rectangular shape.

[0034] The angle cover material 8 conceals the existing frame 3 and the angle 7 from the indoor side. The angle cover material 8 is placed on the indoor side of the existing frame 3 and the angle 7. The angle cover material 8 is fixed to the angle 7. The angle cover material 8 is made of, for example, resin. The angle cover material 8 is formed, for example, by framing long members into a rectangular shape.

[0035] The trim material 9 connects the angle cover material 8 and the frame 2, and conceals the boundary between the angle cover material 8 and the frame 2. The trim material 9 is arranged on the indoor side of the angle cover material 8, on the inner side of the frame 2 in the facing direction. The trim material 9 is fixed to the angle cover material 8 and the frame 2. The trim material 9 is formed, for example, from resin. The trim material 9 has an L-shape in cross section. The trim material 9 is formed, for example, by a long member framed into a rectangular shape.

[0036] Here, in the remodeled fitting 1, the distance between the sill base material 4A and the existing sill 3A in the front view (specifically, the vertical direction) can be adjusted. The fixing structure of the existing sill 3A, sill base material 4A, and new sill 6A will be described below. In the description of the existing sill 3A, sill base material 4A, new sill 6A, and sill cover material 10A, the lower side is the outside in the front view, and the upper side is the inside in the front view.

[0037] The existing lower frame 3A has a step portion 32 and a plurality of guide rails 33.

[0038] The step portion 32 is provided on the outdoor side of the L-shaped member 31A. The step portion 32 is formed in a step-like shape that descends from the indoor side toward the outdoor side.

[0039] Each guide rail 33 is provided on the upper surface of the step portion 32. Each guide rail 33 rises upward from the step portion 32 and extends in the left-right direction. The guide rails 33 include a guide rail 331 for an existing shoji screen, a guide rail 332 for an existing shoji screen, and a guide rail 333 for an existing screen door. The guide rails 331, 332, and 333 are lined up in this order from the inside to the outside of the room.

[0040] The lower frame base material 4A has a base main body portion 41 and an attachment material 42.

[0041] The base main body portion 41 extends in the projection direction. The indoor end of the base main body portion 41 overlaps with the L-shaped member 31A of the existing lower frame 3A when viewed in the vertical direction. The outdoor end of the base main body portion 41 is located directly below the outdoor frame portion 61A. Therefore, the outdoor end of the base main body portion 41 is located outside the room more than the bridge material 63, and the indoor end of the base main body portion 41 is located inside the room more than the bridge material 63. A horizontal plane 41a extending horizontally is formed on the upper surface of the outdoor end of the base main body portion 41.

[0042] The lower frame base material 4A also has an extension portion 41b extending in the vertical direction. The extension portion 41b is provided at the end of the base main body portion 41 on the outside of the room and extends downward from the base main body portion 41. The base main body portion 41 and the extension portion 41b are formed as a single unit. However, this is not limited to this, and the base main body portion 41 and the extension portion 41b may be formed as separate bodies and fixed to each other. The extension portion 41b is formed in a flat plate shape, and the plate surface extends in the direction of view. The lower end of the extension portion 41b is the lower end of the lower frame base material 4A. The lower end of the indoor surface of the extension portion 41b faces, for example, the upper end of the outdoor surface of the guide rail 33.

[0043] A support member 51 is fixed to the surface of the extension portion 41b facing the interior of the room. The support member 51 extends in the vertical direction. Each surface of the support member 51 in the projection direction is a flat surface extending in the projection direction. However, a step is formed in the middle of the support member 51 in the vertical direction. The lower part of each surface of the support member 51 in the projection direction is located closer to the interior of the room than the upper part.

[0044] The extension portion 41b and the support member 51 are inserted by a bolt B1. This fixes the extension portion 41b and the support member 51. The bolt B1 corresponds to an insertion member. The extension portion 41b is provided with a through hole portion 41c that penetrates the extension portion 41b in the projection direction. For example, one through hole portion 41c is provided. The through hole portion 41c is formed, for example, in a long hole shape extending in the projection direction (up and down direction). The support member 51 is provided with a through hole portion 51a that penetrates the support member 51 in the projection direction. For example, one through hole portion 51a is provided. The through hole portion 51a is formed, for example, in a round hole shape.

[0045] The indoor end of the base main body 41 is fixed to the L-shaped member 31A by the bolt B2. The support member 51 abuts against the upper surface of the step portion 32. The outdoor end of the base main body 41 is supported by the step portion 32 via the support member 51. This allows the lower frame base material 4A to be fixed to the existing lower frame 3A while being placed in a predetermined position. The outdoor surface of the support member 51 faces the indoor surface of the guide rail 33. The indoor surface of the extension portion 41b faces the outdoor surface of the guide rail 33. This prevents the lower frame base material 4A from shifting.

[0046] The front-facing distance between the base material and the existing frame varies depending on the dimensions and fit of the existing frame, and therefore varies from construction example to construction example. However, with the remodeled fitting 1, the vertical distance between the lower frame base material 4A and the lower end of the support member 51 can be adjusted by adjusting the position where the bolt B1 is inserted into the extension portion 41b (through hole portion 41c). This allows the vertical distance between the existing lower frame 3A and the lower frame base material 4A to be adjusted to an appropriate size. Therefore, the remodeled fitting 1 has excellent versatility.

[0047] In other words, the remodeled fitting 1 is equipped with an adjustment mechanism 5 capable of adjusting the distance in the front direction between the base material 4 and the existing frame 3. The adjustment mechanism 5 has an extension portion 41b, a support member 51, and a bolt B1. The adjustment mechanism 5 adjusts the position where the bolt B1 is inserted into the extension portion 41b, thereby adjusting the distance in the front direction between the base material 4 and the existing frame 3.

[0048] In addition, since the through-hole portion 41c is formed as a long hole extending in the vertical direction, the vertical distance between the existing lower frame 3A and the lower frame base material 4A can be adjusted steplessly. This makes it possible to preferably prevent the lower frame base material 4A from being installed in an inclined state.

[0049] The attachment material 42 connects the base main body 41 and the lower frame cover material 10A. The attachment material is provided at the outdoor end of the base main body 41. The attachment material 42 has a projection plate portion 42a having a plate-like surface extending horizontally, and a facing plate portion 42b having a plate-like surface extending in the facing direction.

[0050] The projection plate portion 42a is placed on the horizontal surface 41a. The projection plate portion 42a and the base body portion 41 are inserted in the vertical direction by the bolt B3. In this way, the attachment material 42 is fixed to the lower frame base material 4A.

[0051] The sight plate portion 42b is provided at the outdoor side end portion of the attachment material 42. Therefore, the outdoor side end portion of the attachment material 42 serves as a sight surface.

[0052] The outdoor frame portion 61A is fixed to the base main body portion 41 by bolts B4. The indoor frame portion 62A is fixed to the base main body portion 41 by bolts B5. This fixes the new lower frame 6A to the lower frame base material 4A. The outdoor frame portion 61A and the indoor frame portion 62A are connected by a bridge material 63A. An intermediate member 64A is disposed between the indoor frame portion 62A and the base main body portion 41.

[0053] The lower frame covering material 10A is also adjustable in its dimension in the front direction (specifically, the vertical direction). The detailed configuration of the lower frame covering material 10A will be described below.

[0054] As shown in FIG. 4, the lower frame cover material 10A has a cover main body portion 11 and a fin portion 12.

[0055] The cover body 11 is made of a hard material such as metal or hard resin, and more specifically, is made of aluminum. The cover body 11 has an attachment wall 111, a projection wall 112, a fin support 113, a notch 114, and a protrusion 115.

[0056] The mounting wall portion 111 is formed in a flat plate shape, and the plate surface extends in the front direction. The surface of the mounting wall portion 111 facing the interior of the room is a flat surface.

[0057] The projected wall portion 112 extends from the lower end of the mounting wall portion 111 to the outside of the room. The projected wall portion 112 is formed in a flat plate shape, and the plate surface extends along the projected direction and the left-right direction. The projected wall portion 112 is inclined downward from the inside of the room to the outside of the room.

[0058] The fin support portion 113 supports the fin portion 12. The fin support portion 113 is provided at the outdoor side and lower end portion of the projecting wall portion 112. The fin support portion 113 opens downward. A return portion 113a is provided at the peripheral edge of the opening of the fin support portion 113.

[0059] The cutout portion 114 is a break-off groove. The cutout portion 114 is provided in the mounting wall portion 111, and more specifically, is provided on the surface of the mounting wall portion 111 facing the interior of the room. The cutout portion 114 is linear. The cutout portion 114 extends in the left-right direction. The cutout portion 114 is provided, for example, in the center of the mounting wall portion 111 in the up-down direction. The mounting wall portion 111 can be cut more easily at the cutout portion 114 than at a portion where the cutout portion 114 is not provided. The cutout portion 114 corresponds to the cutout portion referred to in the claims.

[0060] The protrusion 115 is provided on the indoor surface of the mounting wall 111. The protrusion 115 protrudes from the mounting wall 111 toward the indoor side. The protrusion 115 is formed in an L-shape in cross section. The indoor end of the protrusion 115 is a rising portion 115a rising upward. A plurality of protrusions 115 are provided at intervals in the vertical direction, and more specifically, two protrusions 115 are provided. In the following, the upper one of the two protrusions 115 may be referred to as the "first protrusion 1151" and the lower one as the "second protrusion 1152."

[0061] The first protrusion 1151 is provided in the vertical middle of the mounting wall 111, more specifically, above the notch 114. The second protrusion 1152 is provided along the lower end of the mounting wall 111. In other words, the notch 114 is provided between the adjacent protrusions 115.

[0062] The mounting wall 111 is provided with bolt holes H penetrating the mounting wall 111 in the prospective direction. The bolt holes H include a first bolt hole H1 and a second bolt hole H2. The first bolt hole H1 is provided in the region between the upper end of the mounting wall 111 and the first convex portion 1151. The second bolt hole H2 is provided in the region between adjacent convex portions 115, below the cutout portions 114 formed in the region.

[0063] The fin portion 12 is fixed to the lower end of the cover body portion 11. The upper end of the fin portion 12 is inserted into an opening of the fin support portion 113 and engages with a return portion 113a provided in the opening. The fin portion 12 is formed, for example, from resin. The fin portion 12 extends in the vertical direction. The fin portion 12 is curved so that its lower end is located closer to the interior side than its upper end. The surface of the fin portion 12 facing the interior side is a curved surface. In other words, the surface of the fin portion 12 facing the interior side is not a flat surface.

[0064] The fin portion 12 has a cutout portion 12a. The cutout portion 12a is a break groove. The cutout portion 12a is provided on the surface of the fin portion 12 facing the interior of the room. The cutout portion 12a is linear and extends in the left-right direction. A plurality of the cutout portions 12a are provided at intervals in the up-down direction. The fin portion 12 can be cut more easily at the cutout portions 12a than at a portion where the cutout portions 12a are not provided. Therefore, by cutting the fin portion 12 at the cutout portions 12a, the vertical dimension of the fin portion 12 can be easily adjusted.

[0065] The lower frame cover material 10A is attached to the lower frame base material 4A via an attachment material 42.

[0066] The indoor surface of the mounting wall portion 111 abuts against the outdoor surface of the attachment material 42 (visible panel portion 61b), and more specifically, the upper portion of the indoor surface of the mounting wall portion 111 abuts against the lower portion of the outdoor surface of the attachment material 42. The upper surface portion of the first convex portion 1151 abuts against the lower end portion of the attachment material 42. The rising portion 115a is located on the indoor side of the attachment material 42. The bolt B6 is inserted through the first bolt hole H1. The bolt B6 is inserted through the mounting wall portion 111 and the attachment material 42. As a result, the lower frame cover material 10A is fixed to the attachment material 42. The mounting wall portion 111 is located directly below the newly installed lower frame 6A (more specifically, the outdoor frame portion 61A).

[0067] As described above, the vertical distance between the lower frame base material 4A and the existing lower frame 3A varies depending on the construction example. If the vertical dimension of the lower frame cover material 10A is too large compared to the vertical distance between the lower frame base material 4A and the existing lower frame 3A, problems such as interference between the lower frame cover material 10A and the lower edge of the opening 101 may occur. Therefore, when the vertical distance between the lower frame base material 4A and the existing lower frame 3A is relatively small, the lower frame cover material 10A is used with the mounting wall portion 111 cut at the notch portion 114.

[0068] 5, when mounting wall portion 111 is cut at cut portion 114, the portion where cut portion 114 was formed before cutting becomes the upper end portion of mounting wall portion 111. Second protrusion 1152 is the uppermost one of protrusions 115.

[0069] The indoor surface of the mounting wall portion 111 abuts against the outdoor surface of the attachment material 42. The upper surface of the second protrusion 1152 abuts against the lower end of the attachment material 42. The bolt B6 is inserted through the second bolt hole H2. This fixes the lower frame cover material 10A and the attachment material 42.

[0070] In this case, the vertical dimension of the lower frame cover material 10A is smaller than before the mounting wall portion 111 is cut. Therefore, even if the vertical distance between the lower frame base material 4A and the existing lower frame 3A is relatively small, the vertical dimension of the lower frame cover material 10A can be prevented from becoming excessively large compared to the vertical distance between the lower frame base material 4A and the existing lower frame 3A. In addition, since the upper end of the mounting wall portion 111 is cut off, the upper end of the lower frame cover material 10A can be prevented from moving upward. This can prevent interference between the lower frame cover material 10A and the newly installed lower frame 6A.

[0071] In addition, the sill cover material 10A covers the existing sill 3A, the sill base material 4A, and the adjustment mechanism 5 from the outside of the room. This can improve the aesthetic appearance of the remodeled fitting 1.

[0072] The remodeling fixture 1 of this embodiment provides the following effects.

[0073] According to this embodiment, the remodeled fitting 1 is provided with an adjustment mechanism 5 capable of adjusting the distance in the front direction between the sill base material 4A and the existing sill 3A. The adjustment mechanism 5 has an extension portion 41b provided on the sill base material 4A and extending in the vertical direction, a support member 51 extending in the front direction (specifically, the vertical direction) and supported by the existing sill 3A, and a bolt B1 that passes through the extension portion 41b and the support member 51, and adjusts the position where the bolt B1 passes through the extension portion 41b to adjust the distance in the front direction (specifically, the vertical direction) between the sill base material 4A and the existing sill 3A.

[0074] The distance between the existing frame and the base material in the visible direction varies depending on the dimensions and fit of the existing frame, and therefore varies depending on the construction example. However, with the remodeling fixture 1, the vertical distance between the existing lower frame 3A and the lower frame base material 4A can be adjusted to an appropriate size by adjusting the position where the bolt B1 passes through the extension 41b and adjusting the vertical distance between the lower frame base material 4A and the lower end of the support member 51. Therefore, a remodeling fixture 1 with excellent versatility can be provided.

[0075] According to this embodiment, the lower frame covering material 10A has an attachment wall portion 111 that abuts against an object to which the lower frame covering material 10A is attached (for example, the attachment material 42), and the attachment wall portion 111 is provided with a cut portion 114.

[0076] The dimensions of the lower frame cover material 10A required vary depending on the construction example. However, the dimensions of the lower frame cover material 10A can be easily adjusted by cutting the mounting wall portion 111 at the notch portion 114. This further increases the versatility of the remodeling fitting 1.

[0077] According to this embodiment, the mounting wall portion 111 is provided with a protruding portion 115 that protrudes from the mounting wall portion 111 toward the indoor side.

[0078] Thereby, for example, by abutting the upper surface of the convex portion 115 against the lower end portion of the attachment material 42, it is possible to suppress misalignment of the lower frame cover material 10A with respect to the lower frame base material 4A.

[0079] According to this embodiment, the protrusion 115 has two protrusions, a first protrusion 1151 and a second protrusion 1152, which are provided at an interval in the vertical direction, and the notch 114 is provided between the protrusions 115 adjacent to each other.

[0080] As a result, when the mounting wall portion 111 is cut at the cutout portion 114, the second convex portion 1152 provided below the cutout portion 114 becomes the uppermost convex portion 115. Therefore, the lower frame covering material 10A can be attached to the attachment material 42 with the region of the mounting wall portion 111 below the cutout portion 114 abutting against the attachment material 42 and with the upper surface of the second convex portion 1152 abutting against the lower end portion of the attachment material 42. As a result, the effect of the convex portion 115 can be obtained even after the dimensions of the lower frame covering material 10A are adjusted.

[0081] According to this embodiment, the mounting wall portion 111 is made of a hard material.

[0082] This improves the strength of the lower frame cover material 10A. In addition, since the mounting wall portion 111 can be easily cut by the notch portion 114, the dimensions can be easily adjusted even if it is made of a hard material.

[0083] Although one embodiment of the renovation fittings of the present disclosure has been described above, the renovation fittings of the present disclosure can be modified as appropriate.

[0084] The remodeled fittings of the present disclosure are not limited to those having the two shoji screens 14 and 15 described above, but may have three or more shoji screens, or may be single-sliding windows with only one shoji screen. Furthermore, the remodeled fittings of the present disclosure may be sliding windows, fixed windows, sash windows, outward-tilting windows, inward-tilting windows, or casement windows.

[0085] In the above embodiment, the through hole portion 41c of the extension portion 41b is a long hole extending in the vertical direction, and the through hole portion 51b of the support member 51 is a round hole, but the configurations of the through hole portion 41c and the through hole portion 51a are not limited to these. For example, the through hole portion 41c may be formed in a round hole shape, and the through hole portion 51a may be formed in a long hole shape. In that case, the vertical distance between the lower frame base material 4A and the lower end portion of the support member 51 can be adjusted by adjusting the position where the support member 51 is inserted by the bolt B1 in the vertical direction. In addition, both the through hole portion 41c and the through hole portion 51a may be formed in a long hole shape. In that case, the distance between the lower frame base material 4A and the lower end portion of the support member 51 can be adjusted in a wider range.

[0086] Furthermore, the through-hole portion 41c may be provided in a plurality of positions spaced apart from each other in the view direction (vertical direction). In this case, the through-hole portion 41c is formed, for example, in a round hole shape. However, the through-hole portion 41c may be formed in an elongated hole shape. By selecting the through-hole portion 41c through which the bolt B1 is inserted from among the plurality of through-hole portions 41c, the vertical distance between the lower frame base material 4A and the lower end portion of the support member 51 can be adjusted. The same applies to the through-hole portion 51a.

[0087] In the above embodiment, the adjustment mechanism 5 is provided in the lower frame base material 4A, but it may be provided in the upper frame base material 4B or each vertical frame base material 4C. The adjustment mechanism 5 may be provided in at least one of the lower frame base material 4A, the upper frame base material 4B, and each vertical frame base material 4C. The adjustment mechanism 5 may be provided in all of these base materials 4.

[0088] In the above embodiment, the notch 114 and the protrusion 115 are provided in the lower frame covering material 10A, but they may be provided in the upper frame covering material 10B or each vertical frame covering material 10C. In addition, the lower frame covering material 10A may not have the protrusion 115. The cross-sectional shape of the protrusion 115 is not limited to an L-shape. For example, the protrusion 115 may not have a rising portion 115a.

[0089] The number of the notches 114 and the protrusions 115 provided is not limited to those in the above embodiment and can be changed as appropriate. The positions at which the notches 114 and the protrusions 115 are provided are not limited to those in the above embodiment and can be changed as appropriate.

[0090] In the above embodiment, the lower frame cover material 10A has the fin portion 12, but the fin portion 12 is not a required component. Also, the fin portion 12 has the notch portion 12a, but the notch portion 12a is not a required component.

[0091] In the above embodiment, the lower frame cover material 10A was attached to the base main body 41 via the attachment material 42, but the attachment material 42 is not a required component. The lower frame cover material 10A may be attached directly to the base main body 41, or may be attached via some kind of member. The object to which the cover material is attached is not particularly limited as long as the cover material can be attached to the base material. [Explanation of symbols]
