Description

[Technical field]

[0001] The present disclosure relates to renovation fittings and a method for installing the same. [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] There may be a step between the new frame and the object to which it is to be attached. The size of the step varies depending on the dimensions and fit of the existing frame, and therefore varies from construction example to construction example.

[0004] According to the fittings of Patent Document 1, the new frame is indirectly or directly attached to the building casing, for example, by an L-shaped angle member interposed between the building's framework and the new frame. The angle member is fixed to the new frame by, for example, a screw. The angle member has a plurality of screw holes. Therefore, the position of the angle member can be adjusted by selecting a screw hole to insert a screw into. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-127632 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the case of the fittings in Patent Document 1, once the new frame is attached to the building's casing, it becomes difficult to attach and remove the screws, making it difficult to adjust the position of the angle members.

[0007] The present disclosure aims to provide a renovation fitting and a construction method for the renovation fitting that allow for easy adjustment of the position of an angle attached to a newly constructed frame. [Means for solving the problem]

[0008] The renovated fitting of the present disclosure is a renovated fitting comprising an existing frame installed in an opening of a building and a new frame attached to the inner periphery of the existing frame, and includes an angle attached to the interior end of the new frame, connecting the new frame and the opening, and an adjustment mechanism having a male member installed on one of the new frame and the angle, and a female member installed on the other of the new frame and the angle, into which the male member is inserted, and the adjustment mechanism is capable of adjusting the front position of the angle by adjusting the depth to which the male member is inserted into the female member.

[0009] The construction method of renovated building materials disclosed herein comprises attaching the new frame to the inner side of the existing frame, inserting the male member into the female member, attaching the angle to the new frame, adjusting the depth to which the male member is inserted into the female member, and adjusting the facing position of the angle.

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in Fig. 1, 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 5 is attached to an existing frame 3 that has already been installed. The opening shape of the opening 101 is approximately rectangular.

[0012] In this specification, "front view direction" refers to the direction in which the faces of the facing materials of the shoji screens 11, 12 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.

[0013] In this specification, the "prospect direction" refers to the thickness direction (i.e., the depth direction) of the surface material of the shoji screens 11 and 12. 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.

[0014] 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 5, a connecting portion 20, a pair of paper screens 11, 12, and a screen door 13. The remodeled fitting 1 is constructed by attaching a new frame 5 via a base material 4 to the inner periphery of the existing frame 3 installed in an opening 101 of a building 100. The remodeled fitting 1 is a sliding window. The paper screens 11, 12 and the screen door 13 are each slidably accommodated inside the new frame 5. Note that the screen door 13 is not shown in Fig. 3.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] The base material 4 is disposed between the existing frame 3 and the new frame 5, and is a member for fixing the new frame 5 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] A cover material 41 is provided on the outdoor end of the base material 4. The cover material 41 extends outward in the viewing direction from the outdoor end of the base material 4. The cover material 41 covers the existing frame 3 and the base material 4 from the outdoor side.

[0025] The new frame 5 is fixed to the inner periphery of the existing frame 3 via a base material 4. An intermediate member 14 such as a spacer is appropriately arranged between the base material 4 and the new frame 5. The new frame 5 is made of an aluminum shaped material. The new frame 5 is formed in a rectangular frame shape. The new frame 5 has a new lower frame 5A, a new upper frame 5B, and a pair of new vertical frames 5C on the left and right.

[0026] The new lower frame 5A is a long member extending in the left-right direction below the opening 101. The new lower frame 5A is divided into two in the projection direction. The new lower frame 5A has an exterior frame portion 51A, an interior frame portion 52A arranged on the indoor side of the exterior frame portion 51A, and a bridge material 53A arranged between the exterior frame portion 51A and the interior frame portion 52A.

[0027] The exterior frame portion 51A and the interior frame portion 52A are each fixed to the lower frame base material 4A. An intermediate member 14A is disposed between the lower frame base material 4A and the newly installed lower frame 5A. The interior side end of the interior frame portion 52A 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.

[0028] The bridge material 53A connects the outdoor frame portion 51A and the indoor frame portion 52A. The bridge material 53A is made of a material having heat insulating properties, and more specifically, is made of a resin having heat insulating properties. The bridge material 53A is formed hollow. This makes it possible to suppress heat transfer between the indoors and outdoors.

[0029] The new upper frame 5B is a long member extending in the left-right direction above the opening 101. The new upper frame 5B has a configuration that generally corresponds to that of the new lower frame 5A. The new upper frame 5B has an outdoor frame portion 51B, an indoor frame portion 52B arranged on the indoor side of the outdoor frame portion 51B, and a bridge member 53B formed from a material having thermal insulation properties and connecting the outdoor frame portion 51B and the indoor frame portion 52B.

[0030] The exterior frame portion 51B and the interior frame portion 52B are each fixed to the upper frame base material 4B. An intermediate member 14B is disposed between the upper frame base material 4B and the newly installed upper frame 5B. The interior end of the interior frame portion 52B 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.

[0031] In addition, when there is no particular need to distinguish between them, the outdoor frame portion 51A and the outdoor frame portion 51B are collectively referred to as the "outdoor frame portion 51", the indoor frame portion 52A and the indoor frame portion 52B are collectively referred to as the "indoor frame portion 52", and the bridge material 53A and the bridge material 53B are collectively referred to as the "bridge material 53".

[0032] Each of the new vertical frames 5C is a long member extending in the up-down direction at both left-right ends of the opening 101. Unlike the new lower frame 5A, each of the new vertical frames 5C is not divided into two in the prospective direction. In this way, the new frame 5 is divided into an exterior frame portion 51 and an interior frame portion 52, and the exterior frame portion 51 and the interior frame portion 52 do not have to be connected by the bridge material 53.

[0033] Each of the outdoor frame portions 51C and each of the indoor frame portions 52C are fixed to each of the vertical frame base materials 4C. Between each of the vertical frame base materials 4C and the newly installed vertical frame 5C, an intermediate member 14C is disposed.

[0034] The new frame 5 also has a groove 55 provided at the end of the new frame 5 facing the interior of the room, into which the protrusion 62 (described in detail later) of the angle 6 can be inserted. The groove 55 extends along the front view direction and opens toward the inside in the front view direction. The inner circumferential surface of the groove 55 is formed of metal, more specifically, aluminum. A return portion 55a is provided at the end of the inner circumferential surface of the groove 55 facing the interior of the room. The return portion 55a is provided on the surface of the inner circumferential surface of the groove 55 facing the exterior of the room.

[0035] The groove portion 55 has a groove portion 55A provided in the new lower frame 5A, a groove portion 55B provided in the new upper frame 5B, and a groove portion 55C provided in each of the new vertical frames 5C. The groove portion 55A is provided at the indoor side end of the indoor side frame portion 52A. The groove portion 55B is provided at the indoor side end of the indoor side frame portion 52B. Each groove portion 55C is provided at the indoor side end of the indoor side frame portion 52C. The groove portion 55A and the groove portion 55B each extend in the left-right direction. Each groove portion 55C each extend in the up-down direction.

[0036] The connecting portion 20 connects the new frame 5 and the opening 101. The connecting portion 20 has an angle 6, an angle cover material 7, and a trim material 8.

[0037] The angle 6 is attached to the end of the new frame 5 on the indoor side. The angle 6 is formed, for example, from resin. The angle 6 is formed, for example, in a square ring shape. The angle 6 is arranged around the four sides of the opening 101. The angle 6 is approximately L-shaped in cross section. The angle 6 has a plate portion 61 and a protrusion portion 62.

[0038] The plate portion 61 is formed in a flat plate shape, and the plate surface extends in a direction perpendicular to the inner side in the finding direction.

[0039] The protrusion 62 protrudes outward in the front direction from the end of the plate 61 facing the interior of the room. The protrusion 62 is shaped like a protrusion extending in a direction perpendicular to the front direction. The protrusion 62 can be inserted into the groove 55. The detailed configuration of the protrusion 62 will be described later.

[0040] The angle cover material 7 conceals the existing frame 3 and the angle 6 from the indoor side. The angle cover material 7 is arranged on the indoor side of the existing frame 3 and the angle 6. The angle cover material 7 is fixed to the angle 6. The angle cover material 7 is formed, for example, from resin. The angle cover material 7 is formed, for example, by framing a long frame material into a rectangular shape. The angle cover material 7 has a covering portion 71 and an angle support portion 72.

[0041] The cover portion 71 is formed in a flat plate shape, and the plate surface extends in the front direction. The cover portion 71 covers the angle 6 and the new frame 5 from the inside of the room.

[0042] The angle support part 72 supports the angle 6 from the outside in the facing direction. The angle support part 72 is attached to the inside part in the facing direction of the surface of the exterior side of the cover part 71, and more specifically, is provided at a position slightly away from the end part of the cover part 71 on the inside in the facing direction to the outside in the facing direction. The angle support part 72 is formed, for example, in a substantially U-shape in cross section. The inside surface of the angle support part 72 in the facing direction is a plane extending in a direction perpendicular to the inside and outside in the facing direction. The inside surface of the angle support part 72 in the facing direction abuts against the outside surface of the angle 6 in the facing direction. The angle 6 and the angle support part 72 are fixed with screws or the like as necessary. The inside surface of the angle 6 in the facing direction and the inside end part of the cover part 71 in the facing direction are flush with each other.

[0043] The angle cover material 7 is capable of adjusting the dimension in the projection direction. The cover portion 71 has a notch portion 74 and a cover protrusion portion 75.

[0044] The cut portion 74 is a folding line. The cut portion 74 is provided on the surface of the cover portion 71 facing the exterior. The cut portion 74 is linear. The cut portion 74 extends in a direction perpendicular to the inner side of the front view direction. A plurality of cut portions 74 are provided lined up in a direction perpendicular to the longitudinal direction of the cut portion 74.

[0045] Cover portion 71 can be easily cut at cut portions 74. Therefore, by cutting cover portion 71 at cut portions 74, the dimensions of cover portion 71 can be easily adjusted.

[0046] The cover protrusion 75 is provided on the surface of the cover portion 71 on the exterior side. The cover protrusion 75 is convex toward the exterior side of the cover portion 71. The cover protrusion 75 extends, for example, in a direction perpendicular to the interior side of the front view direction. A plurality of cover protrusions 75 are provided in a line in a direction perpendicular to the longitudinal direction of the cutout portion 74. The cover protrusions 75 located on the outermost side of the front view direction are provided along the outer end of the cover portion 71 on the exterior side of the front view direction. The cover protrusions 75, except for the cover protrusions located on the outermost side of the front view direction, are provided adjacent to the inner side of the cutout portion 74 on the front view direction. The outer surface of the cover protrusion 75 on the exterior side of the front view direction is parallel to the inner surface of the frame 2 on the interior side of the front view direction.

[0047] The outer end of the angle cover material 7 in the view direction is a flat surface parallel to the inner surface in the view direction of the frame 2. This makes it possible to prevent the angle cover material 7 from tilting when the angle cover material 7 is placed in contact with or close to the frame 2.

[0048] When the cover portion 71 is cut at the cut portion 74, the outer surface of the cover protrusion 75 adjacent to the cut portion 74 becomes the outer end of the angle cover material 7 in the facing direction. Therefore, even after the cover portion 71 is cut at the cut portion 74, the outer end of the angle cover material 7 in the facing direction is a plane parallel to the inner surface of the frame 2 in the facing direction.

[0049] Of the frame members constituting the angle cover material 7, the frame member arranged below the opening 101 is referred to as angle cover material 7A, the frame member arranged above the opening 101 is referred to as angle cover material 7B, and the frame members arranged on the left and right sides of the opening 101 are referred to as angle cover material 7C. In each drawing, the angle cover materials 7A, 7B, and 7C are shown in their respective adjusted dimensions.

[0050] The trim material 8 connects the angle cover material 7 and the frame 2, and conceals the boundary between the angle cover material 7 and the frame 2. The trim material 8 is arranged on the interior side of the angle cover material 7, on the inner side of the frame 2 in the viewing direction. The trim material 8 is fixed to the angle cover material 7, for example, by double-sided tape. The trim material 8 is fixed to the frame 2, for example, by screws. In this way, the new frame 5 and the frame 2 are connected by the angle 6, the angle cover material 7, and the trim material 8. In other words, the new frame 5 and the frame 2 are connected by the connecting part 20. The trim material 8 is formed, for example, from resin. The trim material 8 is formed, for example, by framing elongated members into a rectangular shape. The trim material 8 is L-shaped in cross section.

[0051] The dimensions of the angle cover material 7 are ideally the same as the distance between the inner surface of the angle 6 and the inner surface of the frame 2. However, since the dimensions of the angle cover material 7 are adjusted by cutting at the notches 74, the dimensions of the angle cover material 7 that can be set are somewhat limited. Therefore, the actual dimensions of the angle cover material 7 may deviate slightly from the ideal dimensions.

[0052] For example, if the actual dimensions of the angle cover material 7 are smaller than the ideal dimensions, the cover portion 71 and the trim material 8 are fixed to each other with a distance between the angle cover material 7 and the frame 2. The distance between the angle cover material 7 and the frame 2 is adjusted so that the inner end of the angle cover material 7 in the viewing direction is positioned at a desired position.

[0053] Of the frame materials that make up trim material 8, the frame material arranged below opening 101 is referred to as trim material 8A, the frame material arranged above opening 101 is referred to as trim material 8B, and the frame materials arranged on each of the left and right sides of opening 101 are referred to as trim material 8C.

[0054] However, due to the unevenness of the surface on which the new frame 5 is installed and the manufacturing tolerance of the fittings, the positional relationship between the inner end of the groove 55 in the visible direction and the inner surface of the frame 2 in the visible direction varies depending on the construction example. In addition, the dimensions of the angle cover material 7 that can be set are limited to a certain extent. For this reason, there is still a risk that a discrepancy will occur between the actual positional relationship between the inner end of the groove 55 in the visible direction and the inner surface of the angle support 72 in the visible direction and their ideal positional relationship.

[0055] Therefore, the remodeled fitting 1 is provided with an adjustment mechanism 10 that adjusts the distance between the angle 6 and the new frame 5 in the front direction at the connection between the angle 6 and the new frame 5. The adjustment mechanism 10 is configured with a protrusion 62 and a groove 55. The protrusion 62 corresponds to a male member. The groove 55 corresponds to a female member.

[0056] The adjustment mechanism 10 has an adjustment mechanism 10A provided on the new lower frame 5A, an adjustment mechanism 10B provided on the new upper frame 5B, and an adjustment mechanism 10C provided on each of the new vertical frames 5C. The adjustment mechanisms 10A, 10B, and 10C have corresponding configurations. The configuration of the adjustment mechanism 10 will be described below using the adjustment mechanism 10A as an example.

[0057] In each drawing, the protrusion 62 is shown in an inserted state (in other words, in a deformed state) for the sake of convenience. Fig. 5 shows a case where the protrusion 62 is inserted most deeply into the groove 55A. Fig. 6 shows a case where the protrusion 62 is inserted relatively shallowly into the groove 55A. In the description of the adjustment mechanism 10A, the upper side is the inside in the view direction, and the lower side is the outside in the view direction.

[0058] As shown in FIGS. 5 and 6, the protrusion 62 has a protrusion main body 63 and a projection 65 protruding from the surface of the protrusion main body 63.

[0059] The protrusion body 63 has a generally rectangular plate shape with the plate surface extending in the front direction. The protrusion body 63 has a protrusion shape extending in the left-right direction. The protrusion body 63 is mainly formed of a hard material, more specifically, of a hard resin. However, the surface of the protrusion body 63 facing the exterior is formed of a soft material, more specifically, of a soft resin. In other words, the protrusion body 63 has a soft portion 63a formed of a soft material on its surface facing the interior.

[0060] An inclined portion 63b is provided in the vertical middle portion of the indoor surface of the protrusion main body 63. The inclined portion 63b inclines from the indoor side to the outdoor side as it moves from the top to the bottom (from the inside in the view direction to the outside in the view direction). Of the indoor surface of the protrusion main body 63, the area below the inclined portion 63b (outside in the view direction) is located further outside the room than the area above the inclined portion 63b (inside in the view direction).

[0061] The protrusions 65 are provided in pairs in the projection direction. The protrusions 65 have an exterior protrusion 66 that protrudes from the protrusion body 63 to the exterior side of the room, and an interior protrusion 68 that protrudes from the protrusion body 63 to the interior side of the room.

[0062] The outdoor protrusion 66 is provided at the lower end (outer end in the view direction) of the outdoor surface of the protrusion main body 63. The outdoor protrusion 66 protrudes obliquely upward (inward in the view direction) from the protrusion main body 63 toward the outdoor side. The angle formed by the outdoor surface of the protrusion main body 63 and the indoor surface of the outdoor protrusion 66 is an acute angle. The outdoor protrusion 66 is fin-shaped overall. The outdoor protrusion 66 has a hard portion 66a and a soft portion 66b.

[0063] The hard portion 66a constitutes a portion on the base end side of the exterior protrusion portion 66. The hard portion 66a is made of a hard material, and more specifically, is made of a hard resin.

[0064] The soft portion 66b constitutes a portion of the outdoor side protrusion 66 that is closer to the tip side of the outdoor side protrusion 66 than the hard portion 66a. The soft portion 66b is made of a soft material, more specifically, made of a soft resin. The soft portion 66b is elastically deformable. Although not shown, when the protrusion 62 is not deformed, the outdoor side end of the soft portion 66b is located further outside than the outdoor side end of the hard portion 66a.

[0065] The interface between the hard portion 66a and the soft portion 66b is flat. The upper surface (the inner surface in the view direction) of the hard portion 66a is flat. The angle between the upper surface (the inner surface in the view direction) of the hard portion 66a and the surface of the protrusion body 63 on the outdoor side is a right angle.

[0066] The indoor side protrusion 68 is provided at the lower end (the outer end in the view direction) of the indoor side surface of the protrusion main body 63. The indoor side protrusion 68 protrudes obliquely upward (inward in the view direction) from the protrusion main body 63 toward the indoor side. The angle formed by the indoor side surface of the protrusion main body 63 and the outdoor side surface of the indoor side protrusion 68 is an acute angle. The outdoor side protrusion 66 is fin-shaped overall. The indoor side protrusion 68 is formed entirely from soft resin. The indoor side protrusion 68 is elastically deformable.

[0067] Although not shown, when the protrusion 62 is not deformed, the indoor side end of the indoor side protrusion 68 is located on the indoor side relative to the upper part (the inner part in the view direction) of the indoor side surface of the protrusion main body 63. The upper end (the inner end in the view direction) of the inclined portion 63b is located above (inside in the view direction) the upper end (the inner end in the view direction) of the indoor side protrusion 68, and more specifically, the entire inclined portion 63b is located above (inside in the view direction) the upper end of the indoor side protrusion 68. For this reason, the indoor side protrusion 68 is deformable until its indoor side surface and the indoor side surface of the protrusion main body 63 become flush with each other.

[0068] The angle 6 is formed, for example, by co-extrusion molding of a hard resin and a soft resin.

[0069] The protrusions 62 are capable of being inserted into the grooves 55A, and more specifically, the protrusions 62 are capable of being press-fitted into the grooves 55A while being partially deformed.

[0070] When the protrusion 62 is inserted into the groove 55A, the protrusion 62 (specifically, the outdoor protrusion 66 and the indoor protrusion 68) are in contact with the inner circumferential surface of the groove 55A. In this case, the friction between the protrusion 62 and the inner circumferential surface of the groove 55A suppresses the position of the protrusion 62 from shifting. Therefore, even if the protrusion 62 is inserted relatively shallowly into the groove 55A (see FIG. 6), the angle 6 can be sufficiently fixed to the new frame 5. The adjustment mechanism 10 can easily adjust the vertical position of the angle 6 by adjusting the depth to which the protrusion 62 is inserted into the groove 55A. In addition, the depth to which the protrusion 62 is inserted into the groove 55A can be adjusted steplessly, so that the angle 6 can be finely adjusted in position.

[0071] More specifically, the indoor protrusion 68, with its tip side deformed to move toward the outdoor side, abuts against the indoor side of the inner circumferential surface of the groove 55A. The outdoor protrusion 66, with its tip side deformed to move toward the indoor side, abuts against the outdoor side of the inner circumferential surface of the groove 55A. At that time, the outdoor side end of the hard portion 66a abuts against the outdoor side of the inner circumferential surface of the groove 55A. The soft portion 66b of the outdoor protrusion 66, with its tip side deformed to move toward the indoor side, abuts against the outdoor side of the inner circumferential surface of the groove 55A.

[0072] In addition, the soft portion 66b of the outdoor protrusion 66 and the indoor protrusion 68 are made of a soft material. The soft portion 66b of the outdoor protrusion 66 and the indoor protrusion 68 are in contact with the inner circumferential surface of the groove 55A in a compressed state. In this case, the force of the soft portion 66b of the outdoor protrusion 66 and the indoor protrusion 68 elastically returning to their original shapes can increase the friction between the protrusion 65 and the inner circumferential surface of the groove 55A. This can suitably prevent the protrusion 62 from moving inside the groove 55A.

[0073] An area of ​​the interior side surface of the protrusion body 63 above the inclined portion 63b (inside in the view direction) abuts against the inner circumferential surface of the groove portion 55A. This generates friction between the protrusion body 63 and the groove portion 55A, thereby making it possible to further increase the friction between the protrusion portion 62 and the groove portion 55A.

[0074] The interior surface of the protrusion body 63 is made of a soft material. Therefore, the interior surface (soft portion 63a) of the protrusion body 63 is in a compressed state in contact with the inner circumferential surface of the groove 55A. This can increase the friction between the protrusion body 63 and the groove 55A.

[0075] When the protrusion 62 tries to come out of the groove 55A, the hard portion 66a and the return portion 55Aa engage with each other, more specifically, with the soft portion 66b sandwiched between them. This makes it possible to prevent the protrusion 62 from coming out of the groove 55A even if the protrusion 62 moves in the groove 55A.

[0076] The inner circumferential surface of groove portion 55 may be provided with an uneven portion (not shown) extending in the longitudinal direction of groove portion 55. The uneven portion is preferably formed in a region of the inner circumferential surface of groove portion 55 that is located at a middle portion in the depth direction of groove portion 55. In that case, for example, friction between the surface of protrusion portion 62 and the inner circumferential surface of groove portion 55 can be increased, or the tips of the fins of protrusion portion 65 can be made to catch on the uneven portion, so that movement of protrusion portion 62 within groove portion 55 can be more suitably suppressed.

[0077] Also, the angle 6 may be fixed directly to the frame 2. In other words, the connecting part 20 only needs to have the angle 6, and the angle cover material 7 and the parting material 8 are not essential components. In that case, the position of the inner end of the angle 6 in the facing direction will differ depending on the unevenness of the surface of the frame 2. However, by adjusting the depth to which the protrusion 62 is inserted into the groove 55, such differences can be accommodated.

[0078] Next, a method for constructing the remodeling fixture 1 will be described.

[0079] First, the new frame 5 is attached to the inner periphery side of the existing frame 3 (new frame installation process). At this time, the base material 4 is fixed to the existing frame 3, and the new frame 5 is fixed to the base material 4.

[0080] Next, the protrusion 62 is inserted into the groove 55, and the angle 6 is attached to the new frame 5 (angle attachment process).

[0081] Next, if necessary, the covering portion 71 is cut at the notch 74 to adjust the dimensions of the angle cover material 7 (cover dimension adjustment process). The dimensions of the angle cover material 7 (covering portion 71) should be as close as possible to the distance between the inner surface of the angle 6 in the viewing direction and the inner surface of the frame 2 in the viewing direction. However, there may be a slight discrepancy between the ideal dimensions of the covering portion 71 and the actual dimensions of the covering portion 71.

[0082] Next, the angle cover material 7 is fixed to the frame 2. The angle cover material 7 and the frame 2 are fixed via the trim material 8. For example, the cover portion 71 and the trim material 8 are fixed with double-sided tape, and the trim material 8 and the frame 2 are fixed with screws.

[0083] When the actual dimensions of the covering portion 71 are the same as the ideal dimensions and when the actual dimensions of the covering portion 71 are larger than the ideal dimensions, the angle cover material 7 is positioned so that the outer end of the angle cover material 7 in the view direction abuts against the frame 2, and the covering portion 71 and the parting material 8 are fixed. When the actual dimensions of the covering portion 71 are smaller than the ideal dimensions, the covering portion 71 and the parting material 8 are fixed in a state where the angle cover material 7 and the frame 2 are separated from each other so that the inner surface of the angle cover material 7 in the view direction is positioned as ideally as possible.

[0084] Next, the depth to which the protrusion 62 is inserted into the groove 55 is adjusted, and the position of the angle 6 in the front direction is adjusted (angle position adjustment process). At this time, for example, the protrusion 62 is inserted into the groove 55 until the outer surface of the plate 61 of the angle 6 in the front direction comes into contact with the inner surface of the angle support 72 in the front direction.

[0085] If the actual positional relationship between the inner end of groove 55 in the facing direction and the inner surface of angle support 72 in the facing direction deviates from the ideal positional relationship, it is conceivable that protrusion 62 cannot be inserted to the deepest part of groove 55. However, even if protrusion 62 is inserted relatively shallowly into groove 55, movement within groove 55 is restricted. Therefore, angle 6 is firmly attached to new frame 5. In this way, the position of angle 6 can be easily and precisely adjusted.

[0086] Next, the plate portion 61 of the angle 6 is fixed to the angle support portion 72 with a screw. This fixes the angle 6 and the angle cover material 7, and the new frame 5 is fixed to the opening 101 via the angle 6, the angle cover material 7, the trim material 8, and the frame 2.

[0087] Next, the cover material 41 is attached to the exterior side of the base material 4. With the above, the construction of the remodeling fitting 1 is completed.

[0088] Furthermore, when the angle 6 is fixed directly to the frame 2, the angle attachment process is performed following the new frame installation process. In the angle attachment process, the protrusion 62 is inserted into the groove 55 until the outer surface of the plate 61 of the angle 6 in the front direction comes into contact with the inner surface of the frame 2 in the front direction. At this time, even if there is an unevenness on the surface of the frame 2, for example, the position of the angle 6 can be easily and finely adjusted to match the positional relationship between the inner end of the groove 55 in the front direction and the inner surface of the frame 2 in the front direction. The angle 6 is fixed to the frame 2 with, for example, screws.

[0089] The renovation fixture of this embodiment provides the following effects.

[0090] According to this embodiment, the remodeled fitting 1 is equipped with an adjustment mechanism 10 having a protrusion 62 provided on the angle 6 and a groove 55 provided on the new frame 5 into which the protrusion 62 is inserted. The adjustment mechanism 10 is capable of adjusting the position of the angle 6 in the front direction by adjusting the depth to which the protrusion 62 is inserted into the groove 55.

[0091] This makes it possible to easily adjust the position of the angle 6 in the front direction simply by adjusting the depth to which the protrusion 62 is inserted into the groove 55. Therefore, it is possible to provide a remodeling fixture 1 that allows the position of the angle 6 attached to the new frame 5 to be easily adjusted.

[0092] According to this embodiment, the protrusion 62 has a protrusion-shaped protrusion main body 63 and a projection 65 that protrudes from the surface of the protrusion main body 63 in the projection direction.

[0093] This makes it possible to increase the friction between the protrusions 62 and the inner circumferential surface of the grooves 55, thereby making it possible to preferably prevent the protrusions 62 from moving within the grooves 55.

[0094] According to this embodiment, the protrusion portion 65 protrudes diagonally from the protrusion main body portion 63 toward the inside in the visual direction. More specifically, the outdoor side protrusion portion 66 protrudes diagonally from the protrusion main body portion 63 toward the outside of the room and the inside in the visual direction, and the indoor side protrusion portion 68 protrudes diagonally from the protrusion main body portion 63 toward the inside of the room and the inside in the visual direction.

[0095] This makes it possible to easily insert the protrusions 62 into the grooves 55 and also increases the friction between the protrusions 62 and the inner circumferential surface of the grooves 55 .

[0096] According to this embodiment, the protrusion 65 is made of a soft material. More specifically, the exterior protrusion 66 has a part, including its tip, which is a soft part 66b made of a soft material. The interior protrusion 68 is entirely made of a soft material.

[0097] This allows the protrusions 65 to be easily deformed, making it possible for the protrusions 62 to be more easily inserted into the grooves 55. Furthermore, when the protrusions 65 are inserted into the grooves 55, at least a portion of the protrusions 65 is suitably compressed within the grooves 55. This allows the friction between the protrusions 62 and the inner circumferential surface of the grooves 55 to be increased.

[0098] According to this embodiment, the surface of the protrusion body 63 is made of a soft material. More specifically, the indoor side surface of the protrusion body 63 is a soft portion 63a made of a soft material.

[0099] As a result, when the protrusions 65 are inserted into the grooves 55, the surface of the ridge body 63 is suitably compressed within the grooves 55. As a result, the friction between the ridge body 63 and the inner circumferential surface of the grooves 55 can be increased, and therefore the friction between the ridges 62 and the inner circumferential surface of the grooves 55 can be further increased.

[0100] According to this embodiment, the groove 55 has a barb 55 a that can be engaged with the protrusion 65 .

[0101] As a result, the protrusion 65 gets caught on the return portion 55a, so that even if the protrusion 65 moves inside the groove portion 55, the protrusion 65 can be prevented from coming out of the groove portion 55.

[0102] According to this embodiment, the outdoor side protrusion 66 has a hard portion 66a formed of a hard material. The hard portion 66a is formed to include a base end portion of the outdoor side protrusion 66. The hard portion 66a is engageable with the return portion 55a, more specifically, the hard portion 66a is engageable with the return portion 55a with the soft portion 66b sandwiched therebetween.

[0103] This increases the strength of the base end side of the protrusion 65, so that when the protrusion 65 is caught on the barb 55a, the protrusion 65 is prevented from being deformed and the engagement between the protrusion 65 and the barb 55a is prevented from being released. Therefore, the protrusion 65 can be more reliably prevented from coming out of the groove 55.

[0104] According to this embodiment, the connecting portion 20 includes an angle cover material 7 that covers the angle 6 from the room side. The angle cover material 7 has a cover portion 71 that is plate-shaped and extends in the front direction. The cover portion 71 has a notch portion 74.

[0105] This makes it possible to easily adjust the dimensions of the angle cover material 7.

[0106] The construction method of the renovated fixture 1 of this embodiment includes a new frame installation process in which the new frame 5 is attached to the inner side of the existing frame 3, an angle installation process in which the protrusion portion 62 is inserted into the groove portion 55 and the angle 6 is installed to the new frame 5, and an angle position adjustment process in which the depth to which the protrusion portion 62 is inserted into the groove portion 55 is adjusted and the position of the angle 6 in the facing direction is adjusted.

[0107] This makes it possible to easily attach the new frame 5 to the opening and adjust the forward position of the angle 6 attached to the new frame 5.

[0108] The construction method for the remodeling fixture 1 of this embodiment includes a cover dimension adjustment process in which the cover portion 71 is cut at the notch portion 74 to adjust the dimensions of the angle cover material 7.

[0109] This allows the dimensions of the angle cover material to be easily adjusted. This makes it easier to adjust the position of the angle 6 for each construction example. Even if there is a discrepancy between the actual dimensions of the angle cover material and the ideal dimensions of the angle cover material, the position of the angle 6 can be adjusted in accordance with the discrepancy in the angle position adjustment process.

[0110] 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.

[0111] The remodeled fittings of the present disclosure are not limited to those having the two shoji screens 11 and 12 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.

[0112] In the above embodiment, the adjustment mechanism 10 is provided on all of the top, bottom, left and right frame members that make up the new frame 5, but this is not limited to this. The adjustment mechanism 10 may be provided on only some of the top, bottom, left and right frame members that make up the new frame 5.

[0113] In the above embodiment, the male member is the protrusion 62 of the angle 6, and the female member is the groove 55 of the new frame 5, but this is not limited to this. A female member may be provided on the angle 6, and a male member may be provided on the new frame 5.

[0114] In the above embodiment, the protrusion 62 has the protrusion body 63 and the projection 65, and the surface of the protrusion body 63 facing the interior of the room is made of a soft material, but the surface of the protrusion body 63 facing the exterior of the room may be made of a soft material. Also, as long as the movement of the projection 65 can be sufficiently restricted within the groove 55, the entire protrusion body 63 may be made of a hard material.

[0115] The shape and material of the protrusions 65 are not limited to those in the above embodiment, so long as the protrusions 62 can be inserted into the grooves 55 and can be sufficiently contained within the grooves 55. For example, the protrusions 62 have the protrusions 65, but as long as the protrusions 62 can be sufficiently contained within the grooves 55, the protrusions 62 do not necessarily have to have the protrusions 65. Also, protrusions may be provided on the inner surface of the inserted portion of the female member.

[0116] The components constituting the male and female members are not limited to those in the above embodiment. For example, the male member may be made of metal and the female member may be made of resin.

[0117] In the above embodiment, the connecting part 20 is fixed to the frame 2, but the object to which the connecting part 20 is fixed does not have to be the frame 2. The connecting part 20 only needs to be fixed to the opening 101 of the building 100, and may be fixed to the framework of the building 100, for example. Also, the frame 2 is not an essential component.
