Description

[Technical field]

[0001] The present invention relates to a fixture constructed by installing a new frame for renovation around the inner periphery of an existing frame. [Background technology]

[0002] When renovating fixtures that have already been installed in a building, one method is to leave the existing frame in place and install a new frame around it. This method of renovation eliminates the need to remove the existing frame, shortening the construction period and reducing renovation costs.

[0003] Since normal existing frames are not designed to accommodate the installation of a new frame, the new frame is installed via an attachment (see Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2018-25052 A Summary of the Invention [Problem to be solved by the invention]

[0005] By the way, recent shoji screens are sometimes thicker in the depth direction than traditional shoji screens because they are equipped with double-glazed glass, etc. New frames tend to have larger depth dimensions to accommodate such thick shoji screens, making it difficult to install them in existing frames as is.

[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a fixture that allows a new frame whose projected dimension is larger than that of an existing frame to be properly installed relative to the existing frame. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems and achieve the objective, the fitting of the present invention is a fitting constructed by installing a new frame for renovation around the inner periphery of an existing frame, and is characterized in that the existing frame material of the existing frame and the new frame material of the new frame are fixed via an attachment, and the exterior visible surface of the attachment is located at a position protruding further to the exterior than the exterior visible surface of the existing frame material. Effect of the Invention

[0008] According to the fitting of the present invention, a part of the attachment protrudes outside the room beyond the part of the existing frame material that forms the exterior surface of the existing frame material. Therefore, even if the new frame corresponds to a shoji screen that is thick in the front direction and the new frame material has a correspondingly larger front dimension than the existing frame material, the new frame can be positioned appropriately relative to the existing frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the fitting according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiment.

[0011] Fig. 1 is a vertical cross-sectional view of a fitting 10 according to an embodiment of the present invention. Fig. 2 is a horizontal cross-sectional view of the fitting 10. First, the fitting 10 will be described. The fitting 10 has a new frame 16 attached to it while leaving an existing frame 14 in place. The existing frame 14 is not particularly used in the fitting 10, but not removing it can reduce construction costs.

[0012] The fitting 10 comprises a structure 12, an existing frame 14, a new frame 16, sliding paper screens 18, 20, and a screen door 22. The structure 12 is rectangular with an upper edge 12a, a lower edge 12b, and left and right side edges 12c, and forms an opening 12d. The structure 12 is made of, for example, wood or concrete. The existing frame 14 and the new frame 16 are extruded shapes made of metal such as aluminum alloy, and are configured so that the entire longitudinal length of each frame has a substantially uniform cross-sectional shape.

[0013] In this application, the "visible direction" refers to the indoor / outdoor direction of the fitting 10, that is, the direction from indoors to outdoors or the opposite direction (the direction shown by the arrow Z in the figure). The "visible surface" refers to a surface that extends along the visible direction. The "visible direction" is the direction perpendicular to the visible direction, and in the case of the side edge 12c that is long in the vertical direction, it refers to the left-right direction perpendicular to the longitudinal direction (the direction shown by the arrow X in the figure), and in the case of the upper edge 12a and lower edge 12b that are long in the horizontal direction, it refers to the up-down direction perpendicular to the longitudinal direction (the direction shown by the arrow Y in the figure). The "visible surface" refers to a surface that is along the visible direction.

[0014] The upper edge 12a has a main material 12aa and an existing frame 12ab, which is a secondary material. The side edge 12c has a main material 12ca and an existing frame 12cb, which is a secondary material. The existing frame 14 is rectangular and has an existing upper frame (existing frame material) 14a, an existing lower frame 14b, and existing side frames 14c on the left and right. The existing upper frame 14a, the existing lower frame 14b, and the existing side frame 14c are provided on the inner peripheral side projection surfaces of the main material 12aa, the lower edge 12b, and the main material 12ca of the upper edge 12a, respectively. The existing upper frame 14a has a fin 26a that forms the interior facing surface, two rails 26b, 26c, and a fin 26d that forms the exterior facing surface, which are arranged in the projection direction. The fin 26a abuts against the exterior facing surface of the existing frame 12ab. The fin 26a protrudes slightly inward from the existing frame 12ab, and the fins 26a and 26d cover the rails 26b and 26c so that they are not visible. The rails 26b and 26c have the same length of protrusion into the frame.

[0015] The new frame 16 is rectangular and has a new upper frame (new frame material) 16a, a new lower frame 16b, and new left and right side frames 16c. The new frame 16 is provided on the inner periphery of the existing frame 14, and the new upper frame 16a is provided with a fin 28a that forms the interior sighting surface, and three rails 28b, 28c, and 28d that are lined up in the projection direction. The fin 28a is the part of the new upper frame 16a that is provided closest to the interior and protrudes to the inner periphery. The fin 26d forms the exterior sighting surface. The new lower frame 16b is provided with three rails 30a, 30b, and 30c that are lined up in the projection direction.

[0016] The shoji screen 18 is an outer shoji screen, and is slidably mounted by an upper rail 28c and a lower rail 30b. The shoji screen 20 is an inner shoji screen, and is slidably mounted by an upper rail 28b and a lower rail 30a. The screen door 22 is disposed on the outside of the shoji screen 18, and is slidably mounted by an upper rail 28d and a lower rail 30c. One of the visible surfaces of the newly installed side frames 16c serves as a door stopper for the door edge of the shoji screen 18, and the other visible surface serves as a door stopper for the door edge of the shoji screen 20. The end sides of the shoji screens 18, 20 serve as meeting points.

[0017] In this way, the fitting 10 is a sliding window with two shoji screens 18, 20 that can be slid, but it may be configured as a single sliding window with one of the shoji screens 20 set into the new frame 16, or it may be configured as a sliding door with three or more shoji screens that can be slid. The number of shoji screens installed can be changed as appropriate. The shoji screens 18, 20 each have two pieces of glass and are thick in the front direction. The new frame 16 is compatible with these thick shoji screens 18, 20, and its front direction dimension is larger than that of the existing frame 14.

[0018] The existing upper frame 14a of the existing frame 14 and the new upper frame 16a of the new frame 16 are fixed via a first attachment 34, a second attachment 36, and a third attachment 38. Of these, the first attachment 34 and the second attachment 36 are used in combination. The existing lower frame 14b and the new lower frame 16b are fixed via a lower attachment 42. The existing side frame 14c and the new side frame 16c are fixed via a first side attachment 44, a second side attachment 46, and a third side attachment 47. A spacer 50 is provided between the first upper attachment 34 and the second upper attachment 36.

[0019] The fitting 10 is provided with inner frames (new frames) 40, 48, 49. The inner frame 40 covers at least a portion of the interior facing surface of the existing upper frame 14a and the new upper frame 16a. The inner frame 48 covers at least a portion of the interior facing surface of the existing side frame 14c and the new side frame 16c. The inner frame 49 covers at least a portion of the interior facing surface of the existing lower frame 14b and the new lower frame 16b.

[0020] Next, the fixing portion between the existing upper frame 14a and the new upper frame 16a will be further described. Fig. 3 is an enlarged vertical cross-sectional view of the existing upper frame 14a, the new upper frame 16a and their surrounding areas.

[0021] As shown in Fig. 3, the rail 26c of the existing upper frame 14a and the outer peripheral side wall portion 16aa forming the outer peripheral side visible surface of the new upper frame 16a are connected via a first attachment 34 and a second attachment 36. A spacer 50 is interposed between the second attachment 36 and the outer peripheral side wall portion 16aa.

[0022] The first attachment 34 fixes the existing upper frame 14a and the second attachment 36, and a plurality of attachments are arranged at predetermined intervals along the longitudinal direction of the existing upper frame 14a and the new upper frame 16a. In the following description, the longitudinal direction of the existing upper frame 14a and the new upper frame 16a is referred to as the X direction.

[0023] When the X-direction dimensions of the existing upper frame 14a and the new upper frame 16a are relatively short, there may be only one first attachment 34. The X-direction dimension of the first attachment 34 is set to be appropriately larger than the diameters of the screws B1 and B2.

[0024] The first attachment 34 has a first fixed piece 34a that abuts against the interior facing surface of the rail 26c and is screwed in with a screw B2, and a second fixed piece 34b that is connected to the first fixed piece 34a to form a facing surface and is screwed in with a screw B1 to the second attachment 36. The inner peripheral portion of the second fixed piece 34b forms an inclined surface 34c, and this portion is screwed to the rail 26c with the screw B2. The first attachment 34 further has a first abutment piece 34f that protrudes from the second fixed piece 34b toward the interior of the room via an inclined plate 34e, and a second abutment piece 34d that protrudes slightly toward the exterior from the lower end of the inclined surface 34c.

[0025] The first fixed piece 34a is stable by abutting the interior facing surface of the rail 26c with a moderate area. The inclined surface 34c of the first fixed piece 34a, the second fixed piece 34b, and the inclined plate 34e of the first attachment 34 form a trapezoidal recess in side view. The head of the screw B2 is located within this trapezoidal recess, but is screwed in from the inclined surface 34c, making it easy to hit it with a screwdriver.

[0026] The first abutment piece 34f abuts against the inner peripheral end of the rail 26b. In other words, the first abutment piece 34f abuts against the inner peripheral end of the rail adjacent to the one to which the first fixed piece 34a is screwed. This makes the second fixed piece 34b stable and strong like a double-supported beam. The first abutment piece 34f is sandwiched between the rail 26b and the second attachment 36 and is stable. Since the first abutment piece 34f has an appropriate length in the projection direction, the first attachment 34 can be applied even when the distance between the rail 26b and the rail 26c is slightly different.

[0027] The second abutment piece 34d abuts against the inner peripheral end of the rail 26c. The first abutment piece 34f and the second abutment piece 34d are at the same position in the view direction. Since the protruding lengths of the rails 26b and 26c are equal in the existing frame 14, the first fixed piece 34a comes into surface contact with the rail 26c by the first abutment piece 34f and the second abutment piece 34d abutting against the inner peripheral ends of the rails 26b and 26c, and the second fixed piece 34b can be correctly and easily positioned so as to be horizontal.

[0028] A streak-like surface 34ba is formed on almost the entire inner peripheral side surface of the second fixed piece 34b. The streak-like surface 34ba is composed of many thin streaks adjacent to each other. The streak-like surface 34ba has a so-called triangular wave shape in side view, but may have a sine wave shape, for example. Each streak extends in the X direction, which is suitable for extrusion molding of the first attachment 34. This is because the first attachment 34 has the same shape along the X direction. However, depending on design conditions, the direction of the streaks that make up the streak-like surface 34ba may be other than the X direction.

[0029] The fixed piece 36a of the second attachment 36 and the second fixed piece 34b of the first attachment 34 are fixed by a screw B1. The screw B1 penetrates the fixed piece 36a and then the second fixed piece 34b. Since the fixed piece 36a and the second fixed piece 34b are somewhat spaced apart, if the inner peripheral side surface of the second fixed piece 34b is flat, when the tip of the screw B1 abuts against the second fixed piece 34b, it may shake unstably as it rotates, and there is a concern that the screw B1 may become slanted. Therefore, a certain level of skill is required to screw in the screw B2.

[0030] In contrast, in this embodiment, the lower surface of the second fixed piece 34b is formed with a rib surface 34ba, so that when the tip of the screw B1 abuts against the rib surface 34ba, the tip enters one of the grooves of the grooves, suppressing the shaking. In other words, conceptually, the grooves of the grooves in the rib surface 34ba act similarly to punch holes in a drilling operation. Therefore, the rib surface 34ba allows the screw B1 to be screwed in easily and correctly.

[0031] The first attachment 34 is preferably used for the existing upper frame 14a having the rails 26b and 26c with the same protruding length, but application may be difficult depending on the number and shape of the rails. In such a case, the first attachments 34A and 34B (see Figs. 4 and 5) according to the modified examples described later may be used.

[0032] The second attachment 36 includes a fixed piece 36a, a positioning abutment piece 36b protruding from the outside end of the fixed piece 36a toward the outer periphery, an exterior protruding piece 36c protruding further to the outside from the outside end of the fixed piece 36a, and a cover piece 36d protruding inward from the outside end of the exterior protruding piece 36c. The second attachment 36 fixes the newly installed upper frame 16a to the first attachment 34. The second attachment 36 is formed along the X direction and is basically provided over the entire length of the frame material. The number of second attachments 36 is basically one, but multiple attachments may be connected together depending on the length.

[0033] The second attachment 36 is fixed to the first attachment 34 by screwing a screw B1 from the fixed piece 36a to the second fixed piece 34b. The second attachment 36 is fixed to each of the first attachments 34 by the screw B1. Providing the screw B1 at a position on the second fixed piece 34b close to the rail 26c makes the first attachment 34 even more stable.

[0034] The second attachment 36 is fixed to the new upper frame 16a by screwing the screw B3 from the outer peripheral side wall 16aa through the spacer 50 into the fixed piece 36a. One or more spacers 50 are provided and adjusted to fill the gap between the outer peripheral side wall 16aa and the fixed piece 36a. The spacer 50 has a projection dimension sufficient to abut against the first abutment piece 34f and the second abutment piece 34d via the fixed piece 36a, and reliably supports the fixed piece 36a.

[0035] The screws B3 are provided at predetermined intervals along the X direction and reliably fasten the new upper frame 16a to the second attachment 36. The screws B3 pass through holes 54 in the inner peripheral wall portion 16ab of the new upper frame 16a and reach the outer peripheral wall portion 16aa. The fixing pieces 36a are appropriately long in the projection direction and can be applied to various types of existing upper frames 14a.

[0036] The positioning abutment piece 36b abuts against the indoor facing surface of the outermost fin 26d of the existing upper frame 14a to position the second attachment 36. A pocket is provided at the upper end of the positioning abutment piece 36b, and a sealant 52 is stored in the pocket. The sealant 52 provides a waterproof function between the existing upper frame 14a and the second attachment 36.

[0037] The exterior protruding piece 36c protrudes moderately to the outside of the room along the projection direction. More specifically, the exterior protruding piece 36c protrudes slightly outside the room beyond the rail 28d, which is the outermost part of the newly installed upper frame 16a. The exterior protruding piece 36c forms a horizontal projection surface. In this embodiment, the exterior protruding piece 36c is formed so as to extend almost in the projection direction relative to the fixed piece 36a, but it may be formed at a position slightly shifted up or down. In this embodiment, the exterior protruding piece 36c is in contact with the inner peripheral end of the fin 26d, but it may be slightly separated.

[0038] The cover piece 36d protrudes moderately from the outside end of the exterior protruding piece 36c toward the inner periphery. More specifically, the cover piece 36d protrudes slightly toward the inner periphery from the outer end of the rail 28d, which is the outermost part of the new upper frame 16a. The cover piece 36d forms a vertical sight surface. A pocket is provided at the inner periphery end of the cover piece 36d, and a sealant 52 is stored in the pocket. This sealant 52 provides a waterproof function between the new upper frame 16a and the second attachment 36. In other words, the cover piece 36d has a waterproof function with the new upper frame 16a by the sealant 52, and a function as a cover that covers the outer periphery end of the new upper frame 16a.

[0039] The third attachment 38 is L-shaped, and has a first piece 38a that abuts against the upper surface of the outer peripheral side wall portion 16aa of the new upper frame 16a and is fixed by a screw B4, and a second piece 38b that abuts against the room-side facing surface of the fin 26a of the existing upper frame 14a and is fixed by a screw B5. A plurality of screws B4 and B5 are provided along the X direction. The third attachment 38 is made of an aluminum alloy and is provided in a location including the center of the existing upper frame 14a and the new upper frame 16a in the X direction, but does not extend to both ends in the X direction. In other words, the third attachment 38 is set shorter than the existing upper frame 14a and the new upper frame 16a. The center part of the frame material of the door and window 10 is most likely to bend when subjected to wind pressure, but by providing the third attachment 38 in the center part, it can be appropriately reinforced.

[0040] Furthermore, if the fitting 10 is fireproof, the third attachment 38 should be made of fire-resistant steel and installed over the entire length in the X direction. This will prevent flames from the outside from penetrating into the room.

[0041] The upper half of the interior facing surface of the existing upper frame 14a is covered by the existing frame 12ab, and the lower half is covered by the inner frame 40. The inner frame 40 also covers the interior facing surface of the new upper frame 16a. If the inner frame 40 covers at least the inner peripheral end of the interior facing surface of the existing upper frame 14a and the outer peripheral end of the interior facing surface of the new upper frame 16a, the difference in color and texture at the boundary between the existing upper frame 14a and the new upper frame 16a becomes less noticeable, which is preferable. In addition, the inner frame 40 should cover at least the third attachment 38 so that it is not visible.

[0042] Furthermore, the inner frame 40 is positioned so that its outer peripheral end portion 40a contacts or faces the inner peripheral visible surface 12aba of the existing frame 12ab, and at least does not protrude beyond the existing frame 12ab into the room, so it does not take up space in the room and is not conspicuous in appearance, which is preferable.

[0043] In such a fitting 10, the existing upper frame 14a and the new upper frame 16a are fixed via the first attachment 34 and the second attachment 36 as described above. The second attachment 36 has a simple shape consisting of a fixed piece 36a and an exterior protruding piece 36c extending in the front direction, and a positioning abutment piece 36b and a cover piece 36d extending in the front direction, and is generally applicable regardless of the type of the existing upper frame 14a. The first attachment 34 is preferably used for an existing upper frame 14a of a type in which the two adjacent rails 26 and rails 26c are equal in length, but depending on the shape of the rails, the first attachments 34A and 34B according to the modified examples described below may be used.

[0044] In the fitting 10, the exterior protruding piece 36c of the second attachment 36 protrudes outside the room more than the fin 26d that forms the exterior sighting surface of the existing upper frame 14a, and the cover piece 36d is accordingly positioned at a position that protrudes appropriately outside the room. Therefore, even if the new frame 16 corresponds to the shoji screen 18, 20 that is thick in the projection direction, and the new upper frame 16a also has a projection direction dimension that is larger than that of the existing upper frame 14a, the new frame 16 can be positioned at an appropriate position relative to the existing frame 14. More specifically, the rail 28d that forms the exterior sighting surface of the new upper frame 16a is positioned at a position that is appropriately shifted outside the room more than the fin 26d that forms the exterior sighting surface of the existing upper frame 14a, and the new frame 16 can be appropriately positioned slightly outside the room relative to the existing frame 14. Therefore, the new upper frame 16a does not protrude inside the room.

[0045] In addition, the interior end 16ac of the new upper frame 16a (in this embodiment, the interior end of the outer peripheral side wall 16aa) is disposed outside the interior end face of the existing frame 12ab. This makes it possible to position the outer peripheral end 40a of the inner frame 40 in contact with or facing the inner peripheral side visible face 12aba of the existing frame 12ab.

[0046] Next, modified examples of the first attachment 34 will be described. Fig. 4 is a vertical side view of the first attachment 34A according to the first modified example. Fig. 5 is a vertical side view of the first attachment 34B according to the second modified example. In each modified example, the same components as those in the above embodiment are given the same reference numerals, and detailed description thereof will be omitted.

[0047] As shown in FIG. 4, the first attachment 34A according to the first modification is L-shaped and has a first fixed piece 34a that abuts against the visible surface of the rail 26c and is screwed with a screw B2, and a second fixed piece 34b that is connected to the inner peripheral end of the first fixed piece 34a to form the visible surface. Although not shown in FIG. 4, the second fixed piece 34b is screwed to the second attachment 36 with a screw B1, similar to the above-mentioned first attachment 34 (see FIG. 3). Such a first attachment 34A can be applied to an existing upper frame 14aA that does not have a rail 26b and has only one rail 26c. Depending on the conditions, the first attachment 34A may be fixed to the rail 26b or rail 26c of the above-mentioned existing upper frame 14a (see FIG. 3).

[0048] As shown in Fig. 5, the first attachment 34B according to the second modified example has a first fixed piece 56, an extension piece 58, and a second fixed piece 34b. The second fixed piece 34b is connected to an end of the extension piece 58. Although not shown in Fig. 5, the second fixed piece 34b is fixed to the second attachment 36 by a screw B1, similar to the above-mentioned first attachment 34 (see Fig. 3).

[0049] The first fixing piece 56 has a pair of component pieces 56b connected to the base portion 56a and extending in the front direction. The pair of component pieces 56b face each other in the front direction, and a screw B2 is disposed between them. If the pair of component pieces 56b face each other in the front direction, it is suitable for extrusion molding the first attachment 34B, but they may face each other in a different direction depending on design conditions.

[0050] A plurality of break grooves 56ba are formed in the component piece 56b of the first fixed piece 56. The respective break grooves 56ba are aligned in the viewing direction and extend in the X direction. The length of the component piece 56b can be adjusted by breaking it off at any one of the break grooves 56ba.

[0051] The extension piece 58 protrudes inward from either one of the ends of the base portion 56a in the forward direction so that the first attachment 34B has an appropriate length. The first attachment 34B before construction may be provided with an extension piece 58A as shown by the imaginary line from the other of the ends of the base portion 56a in the forward direction. The extension pieces 58 and 58A have different lengths, and it is advisable to break off one of them and use the other depending on the shape of the existing upper frame 14aB to be constructed.

[0052] The existing upper frame 14aB to which such a first attachment 34B is to be attached is provided with, for example, two rails 26b, 26c, but the rails 26b, 26c are too short to fasten the first attachment 34, or there is an attachment 26ba that becomes an obstacle during fastening. Even in the case of the existing upper frame 14aB to which it is difficult to fasten the first attachment 34, the first attachment 34B according to the modified example can be fastened to the wall portion 14aa that forms the inner peripheral side visible surface of the existing upper frame 14aB by the screw B2.

[0053] In addition, the first attachment 34B is broken off at any one of the multiple breaking grooves 56ba of the component piece 56b of the first fixed piece 56, and by selectively using either one of the two extension pieces 58 and the extension piece 58A, the protruding length from the wall portion 14aa toward the inside of the frame can be adjusted in a variety of ways, making it highly versatile.

[0054] 6 is an enlarged vertical cross-sectional view of an existing upper frame 14a, a new upper frame 16a and their surroundings in a fitting 10A according to a modified example. As shown in FIG. 6, a cover 60 is provided on the fitting 10A.

[0055] The cover 60 covers the exterior facing surface (i.e., the fin 26d) of the existing upper frame 14a of the existing frame 14. The existing upper frame 14a may have a different color or texture from the newly installed upper frame 16a, and it is preferable from the standpoint of appearance to cover it with the cover 60. The cover 60 has an exterior wall portion 60a, an inner peripheral piece 60b, and a roof portion 60c.

[0056] The fin 26d, which forms the exterior visible surface of the existing upper frame 14a, is covered by the exterior wall portion 60a and the roof portion 60c.

[0057] The exterior wall portion 60a is located outside the fin 26d and slightly outside the cover piece 36d of the second attachment 36. The exterior wall portion 60a covers almost the entire surface of the fin 26d and the upper end of the cover piece 36d. The exterior wall portion 60a forms a surface parallel to the fin 26d and the cover piece 36d, but may be non-parallel. The roof portion 60c is a plate piece that connects the upper end of the exposed part of the fin 26d to the upper end of the exterior wall portion 60a, and covers the upper part of the fin 26d. The roof portion 60c is inclined slightly downward toward the exterior, so that rainwater easily flows down.

[0058] The inner periphery piece 60b extends from near the inner periphery end of the exterior wall portion 60a toward the interior of the room along the front direction and abuts against the upper surface of the exterior protruding piece 36c of the second attachment 36. The inner periphery piece 60b is fixed to the exterior protruding piece 36c by a screw B6. The screw B6 screws into the inner periphery piece 60b and the exterior protruding piece 36c from the inner periphery side toward the outer periphery side of the exterior protruding piece 36c.

[0059] When installing the cover 60, a worker in the room can move the cover 60 from the inside of the room to the outside and place the inner peripheral piece 60b on the outside protruding piece 36c as it is. Since the inner peripheral surface of the outside protruding piece 36c is exposed, the worker can screw the screws B6 inside the room. In this way, the installation of the cover 60 can be done from inside the room. In addition, the installation of the new frame 16 to the existing frame 14 of the fittings 10, 10A can basically be done from inside the room. Therefore, even if the construction site is on the second floor or higher, there is no need to set up scaffolding outside the room, and construction can be done without being affected by weather.

[0060] In addition, in the fitting 10A, the cover piece 36d is provided at a position protruding outside the room from the exterior visible surface of the existing upper frame 14a by the exterior protruding piece 36c, so that the structure has a space outside the frame of the exterior protruding piece 36c, and the cover 60 can be suitably arranged in this portion. Note that the inner frame 40A shown in Figure 6 corresponds to the above-mentioned inner frame 40. The inner frame 40A has a different shape from the inner frame 40, but has the same function.

[0061] In the above embodiment, the first attachment 34 and the second attachment 36 are provided between the existing upper frame 14a and the new upper frame 16a, but they may be provided between the existing lower frame 14b and the new lower frame 16b, and between the existing side frame 14c and the new side frame 16c. Other fixing means may be used for the screw fastening parts of each part.

This type of first attachment can be fixed by effectively utilizing the rails of the existing frame material.

[0068] The fixture of the present invention is characterized in that there are multiple rails, the first fixed piece is fixed by abutting against the visible surface of one of the rails, and the first attachment has a first abutment piece that abuts against the inner end of one of the rails adjacent to the one to which the first fixed piece is fixed. Such a first attachment is preferably used when adjacent rails have the same protruding length.

[0069] The fixture according to the present invention is characterized in that the first attachment has a second abutment piece that abuts against the inner peripheral end of the rail to which the first fixed piece is fixed. Such a second contact piece is suitable for use in positioning relative to the rail.

[0070] The building fixture of the present invention is characterized in that the first attachment comprises a first fixed piece fixed to a wall portion forming the inner peripheral visible surface of the existing frame and protruding inwardly from the inner peripheral visible surface, an extension piece protruding further inwardly from the first fixed piece, and a second fixed piece connected to the extension piece to form the visible surface and fixed to the second attachment. Such a first attachment can be fixed to the wall portion that forms the inner peripheral visible surface of the existing frame even if the existing frame material does not have rails or if the rails are not suitable for fixing.

[0071] The building fixture of the present invention is characterized by having a third attachment that fixes the interior visible surface of the existing frame material to the outer periphery visible surface of the newly constructed frame material. The third attachment enables the existing frame material and the new frame material to be fixed more securely.
