The present invention relates to building materials.

Some fittings are equipped with adjustment members such as adjustment screws on the bottom frame to facilitate positioning when supporting the frame on the main body. With this type of fitting, if the screw-in position of the adjustment member is adjusted up or down while the frame is attached to the main body, the position of the frame can be changed via the bottom frame, making it possible to position the frame in the desired position relative to the main body (see, for example, Patent Document 1).

JP 2009-2078 A

However, to adjust the adjustment member, it is necessary to perform the work from the upper side of the sill. Therefore, with this type of fitting, there is a concern that the adjustment member is easily visible from the outside. In the fitting described in Patent Document 1, the upper part of the adjustment member is covered by a cover material, so it is possible to prevent the adjustment member from being directly exposed to the outside. However, the cover material in Patent Document 1 is configured to engage with the sill on the outside of the room, rather than the shoji screen. Therefore, in Patent Document 1, the joint between the sill and the cover material is exposed to the outside over the entire length of the sill, which is not necessarily desirable in terms of appearance quality. Moreover, the joint between the sill and the cover material on the indoor side is configured to protrude most upward on the outside. Therefore, in the fitting described in Patent Document 1, the joint between the sill and the cover material is easily subjected to external forces, and there is a concern that the cover material may easily fall off.

In view of the above, the present invention aims to provide a fixture that can be easily positioned relative to the building frame without compromising the appearance quality.

In order to achieve the above-mentioned objective, the building fixture of the present invention comprises a frame body supported on a main body, and a shoji screen arranged on the frame body so that it can be opened and closed, the lower frame of the frame body is composed of a lower frame main body and an upper layer member arranged on the upper part of the lower frame main body, the upper layer member covers at least the portion of the lower frame main body that faces the underside of the shoji screen to the portion of the lower frame main body facing the outside, and the lower frame main body is provided with adjustment screw holes extending in the vertical direction at a position covered by the upper layer member, the adjustment screw holes are arranged side by side in the forward direction, and an adjustment screw is screwed downward into each of the adjustment screw holes .

According to the present invention, the adjustment member is provided in a position that is covered by the upper layer member, so there is no concern that the adjustment member will be directly visible from the outside. Moreover, the upper layer member covers the entire lower frame body from the part facing the underside of the shoji screen to the part facing the outside. This not only prevents the indoor joint between the upper layer member and the lower frame body from being visible on the outside, which is advantageous in terms of appearance quality, but also eliminates the concern that the upper layer member will easily fall off the lower frame body, as it is less susceptible to the effects of external forces.

A surface along the prospect direction may be called a "finding surface."

(Embodiment 1)
1 and 2 show the lower frame part of the fitting according to the first embodiment of the present invention. The fitting illustrated here is an entrance sliding door in which two doors 1 and 2, which are shoji screens, and a screen door 3 on the inside of the room are arranged to be slidable along the extension direction of the lower frame 11 with respect to a frame 10. In this embodiment 1, a newly installed entrance sliding door for renovation is illustrated, which is installed on a structure B with the existing frame body remaining. However, although not shown in the figure, the renovation method described in the first embodiment is, as described later, a state in which the lower frame C (see FIG. 4) of the existing frame body is removed from the earthen floor B1 which becomes the structure B, and a new frame body 10 is installed with only the upper frame and the left and right vertical frames of the existing frame body remaining on the structure B. Below, the lower frame 11 of the new frame body 10 to be supported by the earthen floor B1 will be described in detail, and the characteristic parts of the present invention will also be described. In the following description, the direction of each component will be specified in the posture in which it is attached to the structure B.

The lower frame 11 of the new frame body 10 is provided between the earthen floor B1 and the porch B2, and is configured with a lower frame body 20 and a rail plate (upper layer member) 30. The lower frame body 20 is an extruded material formed from a metal such as an aluminum alloy, and is configured to have a substantially uniform cross-sectional shape along its entire length. In this embodiment 1, a lower frame body 20 in which the main plate portion 21 and the adjustment plate portion 22 are integrally formed is used.

The main plate 21 is a rectangular flat plate with dimensions approximately equal to the dimensions along the front direction of the frame 10. An abutment plate 23 extending vertically is integrally provided on the edge of the main plate 21 located on the interior side of the room. A protrusion 23a is provided along the longitudinal direction of the abutment plate 23 at a portion located above the main plate 21 on the surface facing the exterior of the room. The gap between the main plate 21 and the protrusion 23a is formed to a dimension capable of accommodating the cover plate 31 constituting the rail plate 30 described below. In addition, a folded wall 24 is integrally provided on the edge of the main plate 21 located on the exterior side of the room. The folded wall 24 extends downward from the edge of the main plate 21 at approximately a right angle, and then bends further toward the interior side of the room at approximately a right angle. The lower end surface of the folded wall portion 24 is at approximately the same height as the lower end of the abutment plate portion 23.

The adjustment plate 22 is flat and arranged so as to be almost parallel to the main plate 21 at a position separated from the underside of the main plate 21, and is provided on a portion of the main plate 21 that extends over almost the entire length of the main plate 21. In this embodiment 1, the adjustment plate 22A on the outdoor side and the adjustment plate 22B on the indoor side are provided at positions that ensure a gap between them, as well as between the abutment plate 23 and the folded wall 24. The adjustment plate 22A on the outdoor side and the adjustment plate 22B on the indoor side have connection walls 25 with the main plate 21 provided on both edges, and are provided at positions that are almost the same distance from the main plate 21. Screw holes 26 are provided at the connection parts between the main plate 21 and the connection walls 25. These screw holes 26 are for screwing in connection screws (not shown) that connect to the vertical frame 12.

As is clear from the figure, the lower frame body 20 has an adjustment screw hole 22a in the adjustment plate portion 22 and an adjustment screw insertion hole 21a in the main plate portion 21. The adjustment screw hole 22a is a through hole along the top and bottom with a screw groove on the inner circumferential surface, and an adjustment screw (adjustment member) 27 can be screwed into it. In the lower frame body 20 of this embodiment 1, adjustment screw holes 22a are formed in a portion of the adjustment plate portion 22A on the outdoor side close to the outdoor side connecting wall portion 25 and in a portion of the adjustment plate portion 22B on the indoor side close to the indoor side connecting wall portion 25. The outdoor side adjustment screw hole 22a and the indoor side adjustment screw hole 22a are paired with each other and are arranged so that their centers are located on the same straight line along the projection direction. The lower frame body 20 has two paired adjustment screw holes 22a, 22a formed in multiple locations along the longitudinal direction. The adjustment screw insertion holes 21a are through holes that run vertically and have an inner diameter that allows the head 27a of the adjustment screw 27 and the tip of the screwing tool to pass through, and are formed at positions that correspond to the individual adjustment screw holes 22a.

The rail plate 30 is made by appropriately processing a thin plate such as stainless steel, and has a cover plate portion 31 and a rail component portion 32. The cover plate portion 31 is a flat plate with the edge portion located on the outside of the room bent downward at an almost right angle, and is formed to a size that can cover almost the entire upper surface 21b of the main plate portion 21 and almost the entire visible surface 24a of the folded wall portion 24 facing the outside of the room. In other words, when the door bodies 1 and 2 are hung on the frame body 10, the rail plate 30 covers the area from the part facing the lower surface of the door bodies 1 and 2 to the edge portion on the outside of the room as a whole. The rail component portion 32 is made by appropriately bending a single steel plate, and three rail portions 32a, two partition plate portions 32b, and five base plate portions 32c are integrally formed. The rail portion 32a is a protruding portion for guiding the sliding of the door bodies 1 and 2 and the screen door 3 described above. The rail portions 32a have approximately the same protruding height. The rail portion 32a located on the innermost side of the room guides the screen door 3. The rail portion 32a guiding the screen door 3 is formed to have a smaller width than the rail portion 32a guiding the door bodies 1 and 2. The partition plate portion 32b is a protruding portion provided between the three rail portions 32a. The partition plate portions 32b have approximately the same protruding height and are slightly smaller than the rail portion 32a. The base plate portions 32c are flat portions extending approximately horizontally at positions at approximately the same height, and are provided in the portion between the rail portion 32a and the partition plate portion 32b and in the portion located further outside the room than the rail portion 32a on the outer side of the room. As shown in FIG. 3, the rail component 32 is configured so that both the longitudinal and longitudinal dimensions are smaller than the cover plate 31, and the three rails 32a are oriented along the longitudinal direction of the cover plate 31 and protrude upward, and are fixed to the top surface of the cover plate 31 by welding or gluing via the base plate 32c.

When installing a new fixture with the above-mentioned sill 11 on the structure B, first remove the screen from the existing fixture, and then remove the existing sill C as shown in Figure 4, and cut out a part of the earthen floor B1 to form an installation surface F for installing the new sill 11.

For the new fittings, vertical frames 12 are attached to both sides of the lower frame 11, and an upper frame (not shown) is attached between the upper ends of the vertical frames 12 to form a framework on all four sides to form the frame body 10. That is, as shown in Figure 5, connecting screws (not shown) are screwed into the screw holes 26 of the lower frame body 20 via the vertical frames 12, thereby connecting the vertical frames 12 to both ends of the lower frame body 20.

As is clear from the figure, at this point, only the lower frame body 20 is framed as the frame body 10, and the rail plate 30 has been removed from the lower frame body 20. In addition, the support bracket 40 is attached to the lower frame body 20. The support bracket 40 is formed by bending a thick plate such as stainless steel, and has a flat support base portion 41, and a mounting plate portion 42 and a support plate portion 43 that extend in a direction that is approximately perpendicular from both side edges of the support base portion 41. The mounting plate portion 42 and the support plate portion 43 extend from the support base portion 41 in opposite directions so as to be approximately parallel to each other. By screwing the screw 45 into the adjustment plate portion 22 of the lower frame body 20 through the mounting plate portion 42, the support bracket 40 is fixed to multiple points of the lower frame body 20 with the support plate portion 43 extending to the outside of the room. The position at which the support bracket 40 is attached is a position that does not interfere with the adjustment screw 27 that is screwed into the adjustment screw hole 22a.

With the support bracket 40 attached to the lower frame body 20, the frame body 10 is temporarily installed on the frame B with the support plate portion 43 abutting against the installation surface F. From this state, as shown in Figures 5 to 8, the adjustment screws 27 are screwed into the respective adjustment screw holes 22a through the adjustment screw insertion holes 21a, and the screwing position of the adjustment screws 27 is adjusted, so that the protruding length of the adjustment screws 27 from the underside of the adjustment plate portion 22 changes. Therefore, if the tip of the adjustment screw 27 abuts against the installation surface F while the screwing position of the adjustment screw 27 is adjusted with the support bracket 40 separated from the installation surface F, the relative position of the lower frame body 20 with respect to the installation surface F changes as shown in Figure 9, and the height position, horizontality, and other posture of the frame body 10 can be set to the desired state. In the illustrated example, the height position and posture of the lower frame body 20 are adjusted so that the upper surface 21b of the main plate portion 21 is approximately horizontal at a height position lower than the upper surface B4 of the floor B1 when the abutment plate portion 23 is in contact with the step surface B3 of the floor B1.

After the height position and posture of the frame body 10 are in the desired state, as shown in Figures 10 and 11, by filling the space between the floor B1 and the lower frame body 20 with mortar M, the lower frame body 20 can be supported by the floor B1. Also, by screwing the screw 35 through the cover plate 31 into the upper surface 21b of the main plate 21, the rail plate 30 can be fixed so that it overlaps the upper surface 21b of the main plate 21, and the rail portion 32a can be provided on the frame body 10. Therefore, by subsequently hanging the door bodies 1, 2 and the screen door 3 on the frame body 10, the new fittings will be installed on the structure B.

As described above, the adjustment screw insertion hole 21a in which the adjustment screw 27 is attached in the lower frame body 20 opens on the upper surface 21b of the main plate portion 21. Therefore, with this fitting, it is possible to easily perform the work of adjusting the height position and posture of the frame body 10 by screwing in the adjustment screw 27. Moreover, the adjustment plate portion 22 into which the adjustment screw 27 is screwed is disposed below the main plate portion 21 in which the adjustment screw insertion hole 21a is formed. Therefore, regardless of the screwing position of the adjustment screw 27, the upper surface 21b of the main plate portion 21 is maintained flat. As a result, after adjusting the adjustment screw 27, the rail plate 30 can be attached without any gaps so as to cover the adjustment screw insertion hole 21a of the lower frame body 20, and the adjustment screw insertion hole 21a and the adjustment screw 27 can be covered and concealed. Furthermore, the rail plate 30 covers almost the entire surface of the upper surface 21b of the main plate portion 21 and almost the entire surface of the folded wall portion 24 facing the outside of the room. This prevents the indoor joint between the rail plate 30 and the lower frame body 20 from becoming a boundary line and appearing outside the room, which is advantageous in terms of appearance quality, and is also less susceptible to external forces, so there is no concern that the rail plate 30 will easily fall off the lower frame body 20. Note that the cover plate 31 is made by bending the edge located on the outdoor side downward, so that the visible surface of the main plate 21 facing the outdoor side can be covered, but the present invention is not limited to this. It is sufficient for the cover plate 31 to cover the entire area from the part of the upper surface 21b of the main plate 21 that faces the lower surface of the door bodies 1 and 2 to the outdoor side edge.

(Embodiment 2)
In the above-mentioned embodiment 1, an example is shown in which a new frame body 10 is installed in a state in which the existing lower frame C is removed from the earthen floor B1, but as in embodiment 2 shown in Figures 12 to 14, it is also possible to install the new frame body 10 in a state in which the existing lower frame C remains on the earthen floor B1. The lower frame 11 illustrated in embodiment 2 includes a lower frame body 20 and a rail plate 30 having the same configuration as the lower frame 11 applied in embodiment 1. However, as shown in Figures 12(a) and 12(b), in addition to the adjustment screw insertion hole 21a and the adjustment screw hole 22a, the lower frame body 20 in embodiment 2 is provided with a mounting screw insertion hole 22b and a tool insertion hole 21c for mounting the mounting screw 50 that fixes the lower frame 11 to the earthen floor B1. The mounting screw insertion hole 22b is a through hole along the top and bottom with an inner diameter larger than the screw shaft portion 50a of the mounting screw 50 and smaller than the head portion 50b, and is formed in the adjustment plate portion 22. In the lower frame body 20 of the second embodiment, mounting screw insertion holes 22b are formed at positions juxtaposed to the adjustment screw holes 22a in the outdoor side adjustment plate portion 22A and the indoor side adjustment plate portion 22B. The tool insertion holes 21c are through holes extending vertically and having an inner diameter that allows the heads 50b of the mounting screws 50 and the tips of the screwing tools to be inserted therethrough, and are formed in the main plate portion 21 at positions corresponding to the individual mounting screw insertion holes 22b.

As is clear from the figure, the bottom frame 11 of the new fixture is configured with a larger dimension along the projection direction than the existing bottom frame C. The adjustment screw insertion holes 21a, adjustment screw holes 22a, mounting screw insertion holes 22b, and tool insertion holes 21c on the indoor side of the bottom frame body 20 are provided at positions corresponding to the existing bottom frame C, and the adjustment screw insertion holes 21a, adjustment screw holes 22a, mounting screw insertion holes 22b, and tool insertion holes 21c on the outdoor side are provided at positions corresponding to the installation surface F of the earthen floor B1 that exceeds the existing bottom frame C.

In the second embodiment, as shown in FIG. 12, the new fixture is framed on all four sides to form the frame body 10, and from this state, the frame body 10 is temporarily installed on the structure B with the lower frame body 20 abutting the existing lower frame C and the installation surface F. In the second embodiment, there is no need to attach the support bracket 40 applied in the first embodiment to the lower frame body 20. At this point, only the lower frame body 20 is framed as the frame body 10, and the rail plate 30 has been removed from the lower frame body 20.

Next, as shown in FIG. 13, from this state, adjustment screws (adjustment members) 27' are screwed into each adjustment screw hole 22a through the adjustment screw insertion hole 21a, and the screwing position of the adjustment screws 27' is adjusted to set the height position and posture of the frame body 10 to the desired state. As is clear from the figure, in embodiment 2, since the support bracket 40 is not applied, an adjustment screw 27' with a screw shaft length shorter than that of embodiment 1 is applied so that the head 27a of the adjustment screw 27' does not protrude upward beyond the upper surface 21b of the main plate portion 21.

After the height position and posture of the frame body 10 are in the desired state, as shown in FIG. 14, the lower frame body 20 can be supported on the floor B1 by screwing the mounting screw 50 into the floor B1 through the tool insertion hole 21c and the mounting screw insertion hole 22b. Also, by screwing the screw 35 into the upper surface 21b of the main board portion 21 through the cover board portion 31, the rail plate 30 can be fixed so that it overlaps the upper surface 21b of the main board portion 21, and the rail portion 32a can be provided on the frame body 10. Therefore, if the door bodies 1 and 2 and the screen door 3 are then hung on the frame body 10, the new fittings will be installed on the structure B. Note that the symbol S in the figure indicates a spacer.

In this second embodiment, the adjustment screw insertion hole 21a in the lower frame body 20 into which the adjustment screw 27' is attached opens to the upper surface 21b of the main plate 21. In addition, the tool insertion hole 21c in the lower frame body 20 into which the mounting screw 50 is attached opens to the upper surface 21b of the main plate 21. Therefore, with this fixture, it is possible to easily adjust the height position and posture of the frame body 10 by screwing in the adjustment screw 27', and it is also possible to easily fix the lower frame 11 by screwing in the mounting screw 50. Moreover, the adjustment plate 22 into which the adjustment screw 27' is screwed is disposed below the main plate 21 in which the adjustment screw insertion hole 21a is formed. Similarly, the adjustment plate 22 against which the head 50b of the mounting screw 50 abuts is disposed below the main plate 21 in which the tool insertion hole 21c is formed. Therefore, regardless of the screwing position of the adjustment screw 27' and the mounting screw 50, the upper surface 21b of the main plate portion 21 is maintained flat. As a result, after the adjustment screw 27' is adjusted and the mounting screw 50 is screwed, the rail plate 30 can be attached without any gaps so as to cover the adjustment screw insertion hole 21a and the tool insertion hole 21c of the lower frame body 20, and the adjustment screw insertion hole 21a, the adjustment screw 27', the tool insertion hole 21c, and the mounting screw 50 can be covered and concealed. Furthermore, the rail plate 30 covers and conceals almost the entire upper surface 21b of the main plate portion 21 and almost the entire visible surface of the folded wall portion 24 facing the outside of the room. Therefore, it is possible to prevent the indoor side joint portion between the rail plate 30 and the lower frame body 20 from becoming a boundary line and appearing outside the room, which is advantageous in terms of appearance quality, and since it is not easily affected by external forces, there is no concern that the rail plate 30 will easily fall off the lower frame body 20. As in the first embodiment, the cover plate 31 does not necessarily have to cover the visible surface of the main plate 21, but only needs to continuously cover the area between the part of the upper surface 21b of the main plate 21 that faces the lower surface of the door bodies 1 and 2 and the edge on the outside of the room.

( Reference example )
As described above, in the first and second embodiments, a sliding door is illustrated in which the door bodies 1, 2, etc. , are arranged to be slidable along the extension direction of the bottom frame 11 relative to the frame body 10. However, the present invention does not necessarily have to be a sliding door, and may be a door in which the door body 5 is supported by a hinge (not shown) so as to be openable and closable in the out-of-plane direction, as in the reference examples shown in Figs. 15 to 17. The door illustrated in the reference example is also a door for renovation, newly installed on the framework B in a state in which all the existing frameworks remain. Below, the bottom frame 111 of the new framework 110 will be described in detail, along with the characteristic parts of the present invention. In the following description, the directions of the respective components will be specified in the state in which the door body is attached to the framework B as a fixture.

The lower frame 111 of the new frame 110 is provided between the earthen floor B1 and the porch B2, and is configured to include a lower frame body 120 and a cover plate (upper layer member) 130. The lower frame body 120 is an extruded shape formed from a metal such as an aluminum alloy, and is configured to have a substantially uniform cross-sectional shape along the entire length along the longitudinal direction. In this reference example , the lower frame body 120 is applied, which includes a main plate portion 121 and an adjustment plate portion 122 formed separately.

The main plate 121 is a rectangular flat plate extending almost horizontally. A visible extension fin 123 is integrally provided on the outside edge of the main plate 121, and a doorstop fin 124, a connecting fin 125, and an abutting fin 126 are integrally provided on the inside edge. The visible extension fin 123 extends downward at almost a right angle from the edge of the main plate 121. In more detail, the upper edge of the visible extension fin 123 bends toward the inside of the room and then extends vertically upward, forming an engagement groove 123b on the upper edge of the visible surface 123a facing the outside of the room. A plurality of ribs 123c are provided toward the inside of the room on the part of the visible extension fin 123 that faces the inside of the room. The doorstop fin 124 extends upward at a right angle from the edge of the main plate 121. A seal member 140 is attached to the part of the doorstop fin 124 facing the outside of the room to ensure watertightness between the door body 5. The connecting fin 125 extends almost horizontally from the middle of the front surface of the doorstop fin 124 facing the room toward the room. The abutting fin 126 extends almost vertically from the edge of the connecting fin 125 located on the inside of the room along the top and bottom, and is configured to face the doorstop fin 124. Screw holes 127 are provided on the underside of the part of the main plate 121 located on the outside of the room and on the underside of the connecting fin 125. These screw holes 127 are for screwing in connecting screws (not shown) that connect to the vertical frame 112.

The adjustment plate 122 is formed integrally with the adjustment base plate 122a, which is a rectangular flat plate, the engagement protrusion 122b protruding from the upper surface of the adjustment base plate 122a, and the engagement plate 122c provided on the outside edge of the adjustment base plate 122a. The engagement protrusion 122b protrudes upward from the upper surface of the adjustment base plate 122a, and is configured so that the protruding end bulges. This engagement protrusion 122b is inserted from its end face into the screw hole 127 provided on the outside of the main plate 121, thereby engaging the adjustment base plate 122a so that they are parallel to each other below the main plate 121. The engagement plate 122c protrudes upward from the edge of the adjustment base plate 122a, bends toward the outside of the room, and protrudes further upward. When the engagement protrusion 122b is inserted into the screw hole 127, the engagement plate portion 122c engages with the rib 123c of the visible extension fin portion 123 and the back surface of the main plate portion 121.

As is clear from the figure, the lower frame body 120 has an adjustment screw hole 122d in the adjustment board portion 122a of the adjustment plate portion 122, and an adjustment screw insertion hole 121a in the main plate portion 121. The adjustment screw hole 122d is a through hole along the top and bottom with a screw groove on the inner circumferential surface, and can be screwed with an adjustment screw (adjustment member) 128. In the lower frame body 120 of this reference example , the adjustment screw hole 122d is formed in a part of the adjustment plate portion 122 that is closer to the room side than the screw hole 127 of the main plate portion 121. Although not shown in the figure, the lower frame body 120 has adjustment screw holes 122d formed at multiple locations along the length. The adjustment screw insertion hole 121a is a through hole along the top and bottom with an inner diameter that allows the head 128a of the adjustment screw 128 and the tip of a screwing tool to be inserted, and is formed at a position corresponding to each adjustment screw hole 122d.

Although not shown in the figure, the lower frame body 120 is also provided with mounting screw insertion holes and tool insertion holes for mounting the mounting screws 150 (see FIG. 16) that fix the lower frame 111 to the earthen floor B1, as in the second embodiment. The mounting screw insertion holes are through holes extending vertically and having an inner diameter larger than the screw shaft portion 150a of the mounting screw 150 and smaller than the head portion 150b, and are formed in the adjustment plate portion 122. The lower frame body 120 of this reference example is provided with mounting screw insertion holes at positions juxtaposed to the adjustment screw holes 122d. The tool insertion holes are through holes extending vertically and having an inner diameter that allows the head portion 150b of the mounting screw 150 and the tip portion of a screwing tool to be inserted, and are formed in the main plate portion 121 at positions corresponding to the individual mounting screw insertion holes.

The cover plate 130 is made by appropriately processing a thin plate such as stainless steel, and is configured to be large enough to cover the majority of the exterior side of the upper surface 121b of the main plate portion 121. More specifically, the dimensions of the cover plate 130 are set so that when the door body 5 suspended from the frame body 110 is closed, that is, when the door body 5 abuts against the seal member 140 of the door stop fin portion 124, it can continuously cover the area from the part facing the lower surface of the door body 5 to the edge located on the exterior side. The edge located on the interior side of the cover plate 130 is in a state where the boundary with the lower frame body 120 is covered by the seal member 140. The edge located on the exterior side of the cover plate 130 is provided with a folded engagement portion 131. The folded engagement portion 131 is formed by folding the edge of the cover plate 130 downward by more than 90 degrees, and the tip portion extends toward the interior side. The dimensions of this folded engagement portion 131 are set so that it can engage with the engagement groove 123b when the cover plate 130 is abutted against the main plate portion 121 of the lower frame body 120.

When installing a new fixture with the above-mentioned bottom frame 111 on the structure B, first remove the screen from the existing fixture, leaving only the frame.

On the other hand, for new fittings, vertical frames 112 are attached to both sides of the lower frame 111, and an upper frame (not shown) is attached between the upper ends of the vertical frames 112 to form a frame body 110 on all four sides. From this state, as shown in FIG. 15, the frame body 110 is temporarily installed on the building body B with the lower frame body 120 abutting against the existing lower frame C. Even in the reference example , it is not necessary to attach the support bracket 40 to the lower frame body 120. At this point, only the lower frame body 120 is framed as the frame body 110, and the cover plate 130 is removed from the lower frame body 120. From this state, as shown in FIG. 16, the adjustment screws 128 are screwed into the respective adjustment screw holes 122d through the adjustment screw insertion holes 121a, and the screwing positions of the adjustment screws 128 are adjusted to set the height position and posture of the frame body 110 to the desired state.

After the height position and posture of the frame body 110 are in the desired state, as shown in FIG. 17, the mounting screw 150 is screwed into the floor B1 through the tool insertion hole and the mounting screw insertion hole. Furthermore, by screwing the secondary mounting screw 151 into the floor B1 through the connecting fin portion 125 of the lower frame body 120 and the existing lower frame C, the lower frame body 120 can be supported by the floor B1.

By screwing the screw 135 into the upper surface 121b of the main plate 121 from this state, the cover plate 130 can be fixed so as to overlap the upper surface 121b of the main plate 121, and the adjustment screw insertion hole 121a and the adjustment screw 128 provided in the main plate 121 can be covered and concealed, as well as the mounting screw insertion hole and the mounting screw 150. The screw 135 for attaching the cover plate 130 is screwed into the part located on the inside of the room of the cover plate 130, and is covered by the underside when the door body 5 is closed. The secondary mounting screw 151 screwed into the connecting fin part 125 is covered and concealed by attaching the door slide 160 made of an elastic material to its upper part. After that, the door body 5 is hung on the frame body 110, and the new fitting is installed on the structure B.

In this reference example , the adjustment screw insertion hole 121a in the lower frame body 120 into which the adjustment screw 128 is attached opens to the upper surface 121b of the main plate portion 121. In addition, the tool insertion hole in the lower frame body 120 into which the mounting screw 150 is attached opens to the upper surface 121b of the main plate portion 121. Therefore, according to this fitting, it is possible to easily perform the work of adjusting the height position and attitude of the frame body 110 by screwing the adjustment screw 128, and it is also possible to easily perform the work of fixing the lower frame 111. Moreover, the adjustment plate portion 122 into which the adjustment screw 128 is screwed is disposed below the main plate portion 121 in which the adjustment screw insertion hole 121a is formed. Therefore, regardless of the screwing position of the adjustment screw 128, the upper surface 121b of the main plate portion 121 is maintained flat. As a result, after the adjustment of the adjustment screw 128, the cover plate 130 can be attached without any gaps so as to cover the adjustment screw insertion hole 121a of the lower frame body 120, and the adjustment screw insertion hole 121a and the adjustment screw 128 can be covered. Furthermore, the cover plate 130 covers the entire area from the part of the main plate 121 facing the lower surface of the door body 5 in the closed state to the edge part located on the outside of the room. Therefore, it is possible to prevent the indoor side joint part between the cover plate 130 and the lower frame body 120 from being exposed to the outside as a boundary line, which is advantageous in terms of appearance quality, and since it is not easily affected by external forces, there is no concern that the cover plate 130 will easily fall off the lower frame body 120. Note that the cover plate 130 does not necessarily have to have the folded engagement part 131, and it is sufficient if it covers the entire area from the part facing the lower surface of the door body 5 to the edge part on the outside of the room.

In the above-mentioned embodiments, all of the examples show fixtures for renovation, but they are not necessarily limited to this and may of course be fixtures for installation on a building frame that does not have an existing frame.
