Description

[Technical field]

[0001] The present invention relates to a door frame and a method for installing the door frame. [Background technology]

[0002] Door and window frames installed indoors are usually secured to an opening in the building frame after the vertical and upper frames are screwed together. Such door and window frames can be as large as 4m or more in width, making them difficult to handle when in the assembled state. Therefore, there is also a method of securing the vertical and upper frames separately to the opening (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4708551 Summary of the Invention [Problem to be solved by the invention]

[0004] By the way, some door and window frames have a concave groove on the visible surface of the vertical frame. In this case, the upper frame is inserted into the groove of the vertical frame, so it is not easy to fix the vertical frame and the upper frame separately to the opening. For example, if you try to fix the vertical frame to the framework first and then the upper frame, the upper frame will interfere with the vertical frame, making the assembly difficult, and there is a concern that the frame material will be damaged if you try to assemble it forcibly.

[0005] The present invention has been made in consideration of the problems with the prior art described above, and aims to provide a door frame and a door frame installation method that allow the vertical frame and upper frame to be fixed separately and easily to the main body. [Means for solving the problem]

[0006] The door and window frame of the first aspect of the present invention is a door and window frame to be attached to an opening in a building's main structure, and comprises left and right vertical frames fixed to the main structure with a first fixing device, and an upper frame fixed to the main structure with a second fixing device and provided between the left and right vertical frames, wherein the vertical frames have a first sight portion extending inward from one side of the sight surface in the front direction, and the first sight surface on one side of the upper frame in the front direction abuts the first sight portion of the vertical frames.

[0007] A method of installing a door and window frame according to a second aspect of the present invention is a method of installing a door and window frame to an opening provided in the main body of a building, which uses left and right vertical frames as the door and window frames, each having a groove portion provided on its projection surface and a first projection portion forming one of a pair of side walls of the groove portion provided in the projection direction and a second projection portion forming the other, and an upper frame having protrusions at both longitudinal ends that fit into the grooves, and includes a first step of fixing the left and right vertical frames to the opening, a second step of passing the upper frame in the projection direction through a cutout portion formed at the upper end of the second projection portion of the vertical frame after the first step, a third step of positioning the upper frame in the projection direction relative to the vertical frames by abutting the projection surface at the leading end against the first projection in the direction of movement of the projection portion in the projection direction, and a fourth step of fixing the upper frame to the opening after the third step. Effect of the Invention

[0008] According to the above aspect of the present invention, the vertical frame and the upper frame can be fixed separately and easily to the main body. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the door and window frame and its installation method according to the present invention will be described in detail with reference to the accompanying drawings.

[0011] As shown in Figs. 1 to 3, the door frame 10 according to the first embodiment is fixed to an opening 12a of a building frame 12 of a building 11, and supports a shoji screen 14 inside so that the screen can slide in the X direction. The door frame 10 is used, for example, as a door that separates a room (room A) from a room (room B) in the building 11. The door frame 10 may also be used as a door that separates a room from a corridor. The building frame 12 is, for example, a pillar or a wall. In this embodiment, a single sliding door door that supports one shoji screen 14 is exemplified, but the door frame 10 may also be a sliding door door that slidably supports two shoji screens.

[0012] The door frame 10 has left and right vertical frames 16L, 16R (hereinafter, sometimes collectively referred to as "vertical frames 16"), an upper frame 17, and a lower frame 18. Each of the frames 16-18 is, for example, an extruded aluminum alloy material. In the door frame 10 of this embodiment, each of the frames 16-18 is fixed separately to the framework 12. For this reason, before being fixed to the framework 12, the door frame 10 is carried into the building 11 as each of the frames 16-18 as individual components.

[0013] In this application, the "visible direction" refers to the depth direction of the door frame 10, that is, the direction from room A to room B or the opposite direction (the direction indicated by the arrow Z in the figure), and the "visible surface" refers to a surface extending along the visible direction. The "visible direction" refers to a direction perpendicular to the visible direction, and in the case of a vertical frame 16L or the like that is long in the vertical direction, it refers to the left-right direction perpendicular to the longitudinal direction (the direction indicated by the arrow X in the figure), and in the case of an upper frame 17 or the like that is long in the horizontal direction, it refers to the up-down direction perpendicular to the longitudinal direction (the direction indicated by the arrow Y in the figure). The "visible surface" refers to a surface along the visible direction. The inside (inner circumference) of the door frame 10 refers to the part inside the frame of the door frame 10. The outside (outer circumference) of the door frame 10 refers to the part outside the frame that is fixed to the building structure of the door frame 10.

[0014] 3 to 5B, the vertical frames 16L, 16R each have a groove portion 20, a first sight portion 21, and a second sight portion 22. In the present embodiment, the vertical frames 16L, 16R only require the same shaped members to be arranged symmetrically, and therefore, in the following, the components of the vertical frames 16L, 16R are given the same reference numerals and duplicated explanations are omitted, and the same applies to the vertical frames 54L, 54R described below.

[0015] The groove 20 is a wide concave vertical groove that extends over the entire length of the front surface of the vertical frame 16 in the longitudinal direction. The groove 20 is a door shim for filling the gap between the door screen 14 and the vertical frame 16 when the door screen 14 is fully closed or fully open. In the configuration example shown in Fig. 3, the groove 20 of the vertical frame 16L accommodates the tail of the door screen 14 in the fully open position, and the groove 20 of the vertical frame 16R accommodates the tip of the door screen 14 in the fully closed position. A narrow pocket 20b that is recessed by one step is formed at approximately the center in the front direction of the bottom surface 20a of the groove 20. The pocket 20b is an attachment portion of the door stopper 24 that abuts against the front surface of the tail or tip of the door screen 14 (see Fig. 3).

[0016] The first sight portion 21 extends inward from one side of the sight surface in the sight direction, and forms one of the side walls of a pair of groove portions 20 provided in the sight direction (the sight surface on the Room B side in this embodiment). The vertical frame 16 in this embodiment has a hollow portion with a cross-sectional shape similar to the number 1. The first sight portion 21 is formed by a wall panel of the hollow portion of this vertical frame 16. The first sight portion 21 may be formed by a fin-shaped plate piece or the like.

[0017] The second visible portion 22 forms the other of the pair of side walls of the groove portion 20 provided in the projection direction (in this embodiment, the visible surface on the A-room side). The second visible portion 22 is a plate piece protruding from the hollow portion of the vertical frame 16, and has a substantially L-shaped cross section.

[0018] The second sight portion 22 has a first portion 22a and a second portion 22b. The first portion 22a is a portion that forms the side wall (sight surface) of the groove portion 20. The second portion 22b protrudes from the end of the first portion 22a in a sight direction away from the groove portion 20 (direction from chamber B toward chamber A). The second portion 22b forms a sight surface 22c on the chamber A side of the groove portion 20. The second sight portion 22 may be composed of a hollow wall panel or a linear plate piece similar to the first sight portion 21.

[0019] As shown in Fig. 4A etc., a notch 26 is formed at the upper end of the second visible portion 22. The notch 26 is formed by cutting away a predetermined range from the upper end surface of the portions 22a, 22b of the second visible portion 22. As a result, the notch 26 cuts out the wall portion on the A-room side of the groove portion 20, thereby exposing the upper portion of the groove portion 20 when viewed from the A-room side of the vertical frame 16.

[0020] 2 and 4A to 7B, the upper frame 17 has a guide rail portion 28, a first attachment 29, a second attachment 30, and a protruding portion 32. The guide rail portion 28 and the attachments 29, 30 are each an extruded member.

[0021] The guide rail portion 28 is a portion that guides the sliding door 14. The guide rail portion 28 has a downward rail 28a on the inner surface of the frame along which the upper door roller 33a attached to the upper end surface of the sliding door 14 runs (see FIG. 2).

[0022] The first attachment 29 is detachably mounted on the sight surface (first sight surface) 28b on the Room B side of the guide rail portion 28. In this embodiment, the first attachment 29 is a square tube-shaped member having a rectangular hollow portion. The first attachment 29 is detachably attached to the guide rail portion 28, for example, by a claw protruding from the sight surface engaging an engagement groove formed in the sight surface 28b of the guide rail portion 28. With the protrusion 32 of the upper frame 17 housed in the groove portion 20 of the vertical frame 16, the first attachment 29 is arranged so that its end face abuts against the sight surface 16a on the Room B side of the groove portion 20 of the vertical frame 16.

[0023] The second attachment 30 is detachably attached to the sighting surface 28c on the A-room side of the guide rail portion 28. The second attachment 30 in this embodiment is a plate-like member with a substantially L-shaped cross section. The second attachment 30 has a sighting portion 30a facing the sighting surface 28c, and a recessed portion 30b bent from the lower end of the sighting portion 30a toward the A-room side. The sighting portion 30a is attached to the sighting surface 28c of the upper frame 17 with the same or similar detachable structure as the first attachment 29. The recessed portion 30b forms the sighting surface 30c on the A-room side of the upper frame 17.

[0024] The upper frame 17 does not have a structure using the attachments 29, 30, and the guide rail portion 28 and the attachments 29, 30 may be integrally formed as a single shaped member, or only one of the attachments 29, 30 may be integrally formed with the guide rail portion 28. When the upper frame 17 has an attachment structure as in this embodiment, it is possible to accommodate various specifications having different structures, such as a sliding structure, while sharing one or two parts of the guide rail portion 28 and the attachments 29, 30, and this is highly versatile.

[0025] The protrusions 32 are provided on both the left and right ends of the upper frame 17. The protrusions 32 are portions whose central portion protrudes in the longitudinal direction further than both side portions in the projection direction of the upper frame 17, and fit into the groove portion 20 with almost no gap. Therefore, the projection width of the protrusions 32 is set to be less than the projection width of the groove portion 20.

[0026] The protruding portion 32 in this embodiment is composed of the guide rail portion 28 and the sighting portion 30a of the second attachment 30 (see FIG. 4A). That is, in the upper frame 17, the guide rail portion 28 and the sighting portion 30a of the second attachment 30 are configured to have a longer overall length than the sighting portion 30b of the first attachment 29 and the second attachment 30. Therefore, the end faces of the sighting portions 30b of the first attachment 29 and the second attachment 30 are located in a position retreated in the longitudinal direction from the tip surface of the protruding portion 32 (see FIG. 6A). That is, the sighting portion 30b of the second attachment 30 protrudes toward the A room side from a position retreated from the tip surface of the protruding portion 32 on the sighting surface (second sighting surface) 30d of the sighting portion 30a constituting the A room side sighting surface of the upper frame 17.

[0027] As shown in Fig. 7A, the upper frame 17 is configured such that the height h1 of the upper frame 17 is less than the height h2 of the notch 26, and preferably h1 is somewhat smaller than h2. As a result, as described below, the upper frame 17 can incorporate the protrusion 32 into the groove 20 through the notch 26 of the left and right vertical frames 16L, 16R. Also, as described above, in the upper frame 17, the end face of the protrusion 30b of the second attachment 30 is located at a position set back from the end face of the protrusion 32. Therefore, with the protrusion 32 housed in the groove 20, the protrusion 30a of the second attachment 30 is disposed in the notch 26, complementing the second protrusion 22 of the vertical frame 16 (see Figs. 4B and 5B).

[0028] As shown in FIG. 2, the bottom frame 18 is a part for guiding the shoji screen 14 so that it can slide. The bottom frame 18 has an upward rail 18a on its inner projection surface along which the lower door rollers 33b, part of which is exposed from the lower end surface of the shoji screen 14, run. The bottom frame 18 is disposed between the left and right vertical frames 16L, 16R. The bottom frame 18 is disposed so as to straddle the gap G between the floor 34A of room A and the floor 34B of room B, and its center portion is inserted into the gap G and screwed to the base material under the floor. For example, if the shoji screen 14 is a hanging door or the like that does not have the lower door rollers 33b, the bottom frame 18 may be omitted.

[0029] As shown in Fig. 3, the building 11 of this embodiment has a sleeve wall 36 that houses, for example, the shoji screen 14 in a fully open position. A middle mullion 38 is fixed to the end of the sleeve wall 36. The middle mullion 38 is an extruded member made of the same material as the upper frame 17 etc., and stands up, for example, on the side of the upper frame 17 and lower frame 18 on the Room B side. The middle mullion 38 slides against the surface of the shoji screen 14 on the Room B side, and serves as an attachment point for mohair 39 to close the gap between the shoji screen 14 and the sleeve wall 36. The sleeve wall 36 and middle mullion 38 may be omitted.

[0030] Next, a method for attaching the door frame 10 to the framework 12 and its functions and effects will be described.

[0031] 8, the left and right vertical frames 16L, 16R are inserted into the opening 12a of the frame 12 and fixed to the frame 12 with the first fasteners 40 in the first step (see FIG. 3). The first fasteners 40 are, for example, screws.

[0032] Next, in step S2 in Fig. 8, a second process is performed in which the upper frame 17 is passed through the cutouts 26 of the left and right vertical frames 16L, 16R in the projection direction from the A room side to the B room side (see Figs. 4A, 5A, 6A, and 7A). At this time, since the projection height h1 of the upper frame 17 of the door and window frame 10 is less than the height h2 of the cutouts 26, the upper frame 17 can be smoothly passed through the cutouts 26.

[0033] Since the second attachment 30 of the upper frame 17 has a recessed portion 30b in addition to the visible portion 30a, when it is inserted between the vertical frames 16L, 16R at an angle and then lifted upward, the recessed portion 30b inevitably interferes with the second visible portion 22 (second portion 22b) of the vertical frame 16. In this regard, the door and window frame 10 allows the upper frame 17 to be inserted between the vertical frames 16L, 16R from the front through the cutout portion 26, making the work smooth and preventing damage to the frame material.

[0034] 8, the third step is executed to position the upper frame 17 in the projection direction relative to the left and right vertical frames 16L, 16R by abutting the sighting surface 28b on the leading side (Room B side) in the moving direction of the protrusion 32 against the sighting surface of the first sighting portion 21 of the groove portion 20 (see FIGS. 4B, 5B, 6B, and 7B). In this way, the door and window frame 10 has the notch 26 only on the second sighting portion 22 on the near side in the insertion direction of the upper frame 17 relative to the vertical frame 16, and does not have the notch 26 on the first sighting portion 21 on the opposite side. Therefore, the upper frame 17 can be easily positioned in the projection direction relative to the vertical frame 16 by simply passing the notch 26 and abutting the sighting surface 28b against the first sighting portion 21 of the groove portion 20, making the assembly work easy. 6A to 7B only show the relationship between the vertical frame 16R and the upper frame 17, but the relationship between the vertical frame 16L and the upper frame 17 is symmetrical to that shown in each of these figures.

[0035] Finally, in step S4 in Fig. 8, a fourth step is performed in which the upper frame 17 is fixed to the frame 12 with second fasteners 41 (see Fig. 2). The second fasteners 41 are, for example, screws.

[0036] This completes the installation work of the fitting frame 10 to the skeleton 12. This installation method makes it easy to individually fix the vertical frame 16 and the upper frame 17 to the skeleton 12. As a result, the fitting frame 10 can be easily brought into the building 11 even if the upper frame 17 is large, for example, with a length of 4m or more, and the occurrence of a situation in which the frames 16-18 are deformed during the installation work can be suppressed.

[0037] The lower frame 18 may be installed, for example, before or after the installation process (steps S2 to S4 in FIG. 8) of the upper frame 17. The lower frame 18 can be easily installed by disposing it diagonally in the up-down direction between the left and right vertical frames 16L, 16R and then slowly lowering it.

[0038] In the case of the configuration example shown in FIG. 2 and FIG. 3, after the fitting frame 10 is fixed to the main body 12 and the sleeve wall 36, a work of appropriately attaching a wall panel 42 such as a plasterboard around it is also performed. In the case of this embodiment, the wall panel 42 is attached to the upper frame 17 so as to cover and hide most of the visible surface on the B-room side of the first attachment 29, and to cover and hide most of the visible surface outside the frame of the projection part 30b protruding to the A-room side of the second attachment 30. The wall panel 42 is attached to the vertical frame 16L so as to cover and hide most of the visible surface outside the frame of the second part 22b protruding to the A-room side. The wall panel 42 is attached to the vertical frame 16R so as to cover and hide most of the visible surface on the B-room side, and further to cover and hide most of the visible surface outside the frame of the second part 22b protruding to the A-room side. As a result, when viewed from the A-room and B-room sides, the majority of the door and window frame 10 is covered and hidden by the wall panel 42, with the exposed portion being extremely narrow, resulting in a high quality appearance.

[0039] As described above, in the door and window frame 10 of this embodiment, the vertical frames 16L, 16R have a notch 26 at the upper end of the second sight portion 22 that forms the side wall of the groove portion 20, and the upper frame 17 has one side sight surface 28b abutting against the first sight portion 21 of the vertical frames 16L, 16R in the prospective direction of the protrusion 32 when the protrusion 32 is fitted into the groove portion 20.

[0040] That is, by providing the above-mentioned configuration to the fitting frame 10, when the vertical frame 16 and the upper frame 17 are fixed separately to the framework 12, the upper frame 17 can be easily disposed between the left and right vertical frames 16L, 16R through the notch 26 of the vertical frame 16 previously fixed to the framework 12. Moreover, the upper frame 17 can be easily positioned in the projection direction relative to the vertical frame 16 because its sight surface 28b abuts against the first sight portion 21 of the vertical frame 16 with the protrusion 32 housed in the groove 20. That is, the fitting frame 10 can easily and precisely align the positions of the vertical frame 16 and the upper frame 17 in the projection direction, and even though the fitting frame 10 has a configuration in which the vertical frame 16 and the upper frame 17 are fixed separately, the entire frame is disposed substantially flush in the projection direction, and high appearance quality is obtained.

[0041] In the door frame 10, with the protrusion 32 housed in the groove 20, the upper frame 17 has the A-side sighting surface 30d of the protrusion 32 positioned in the cutout 26, thereby complementing the second sighting portion 22 of the vertical frame 16. For this reason, as shown in Figures 1, 4B, and 5B, after the door frame 10 is assembled to the building frame 12, the cutout 26 is covered by the sighting surface 30d of the upper frame 17 and is barely noticeable, and the cutout 26 does not impair the appearance quality.

[0042] As shown in Figures 1, 4B, and 5B, in the door frame 10, the projection portion 30b of the upper frame 17 is disposed perpendicular to the second portion 22b of the vertical frame 16, and forms a corner portion C between the second portion 22b. That is, the projection surfaces 22c, 30c on the A-room side of the door frame 10 form a smooth corner portion C with only a small gap between them. Therefore, the door frame 10 can ensure the appearance quality when viewed from the inside of the frame or the A-room side. The corner portion C may be protected by attaching a resin corner part 44 as shown in Figure 1.

[0043] Next, a fitting frame 50 according to a second embodiment will be described with reference to Figures 9 to 12B. In the fitting frame 50 according to the second embodiment, elements that are the same as or similar to those in the fitting frame 10 according to the first embodiment are given the same reference numerals and detailed descriptions thereof will be omitted.

[0044] As shown in Figs. 9 and 10, the door frame 50 is fixed to the opening 12a of the main body 12 and supports the sliding door 14, which is a folding door, so that the door frame 50 can be folded. The door frame 50 is used, for example, as a door that separates a room (inside) from a closet (inside storage) in the building 11. The door frame 50 has left and right vertical frames 54L, 54R (hereinafter, sometimes collectively referred to as "vertical frames 54"), an upper frame 55, and a lower frame 56. Each of the frames 54 to 56 is, for example, an extruded shape made of an aluminum alloy.

[0045] Each of the vertical frames 54L and 54R has a projection surface 58, a projection portion (first projection portion) 59, and a projection piece 60.

[0046] The front surface 58 faces the door tip or the door tail of the shoji screen 14 when the shoji screen 14 is fully closed or fully opened. The front surface 59 is a plate piece that protrudes from the storage interior side of the front surface 58 to the inside of the frame in the front direction. The front surface piece 60 is a plate piece that protrudes from the front surface 58 to the room side. The front surface piece 60 forms the front surface 22c located on the room side of the shoji screen 14. The front surface 59 and the front surface piece 60 may be made of a hollow wall panel or the like, similar to the first front surface piece 21 shown in FIG. 3. As shown in FIG. 12A and FIG. 12B, a relief portion 60a is formed at the upper end of the front surface piece 60. The relief portion 60a is a cutout to prevent interference with the wall panel 42.

[0047] As shown in FIG. 10, in the vertical frame 54 of this embodiment, the visible surfaces 22c, 58 are continuous from the interior side toward the interior of the storage space, so that the visible portion 59 is exposed when viewed from the front from the interior side.

[0048] The upper frame 55 has an upper frame main body portion 62 and a guide rail portion 28. The upper frame main body portion 62 is configured with a first fixing device 41 on the framework 12. The upper frame main body portion 62 has, in the projection direction from the room side toward the storage interior side, a projection portion 30b (projection surface 30c), a rail holding portion 62a, and a surface forming portion 62b, in that order.

[0049] The rail holding portion 62a is formed in a downward concave shape, and the guide rail portion 28 is attached to the inside. After the guide rail portion 28 is inserted into the rail holding portion 62a, it is fixed to the main body 12 with fasteners 64 such as screws. The surface forming portion 62b is a plate-like portion formed in an L-shape. The surface forming portion 62b forms a visible surface 62c on the inner side of the storage compartment than the guide rail portion 28, and a sighting surface (first sighting surface) 28b facing the inner side of the storage compartment. The upper frame 55 may also have an attachment structure similar to that of the upper frame 17 shown in FIG. 2.

[0050] The lower frame 56 is a part for guiding the shoji screen 14. The lower frame 56 has a rail 56a on the inner surface of the frame along which the guide roller 33c runs, the guide roller 33c being partially exposed from the lower end surface of the shoji screen 14. The lower frame 56 is fixed onto the floor 66.

[0051] Next, a description will be given of a method for attaching the door frame 50 to the framework 12 and its functions and effects. The attachment method of this embodiment is performed in substantially the same manner as in the first embodiment described above.

[0052] First, the left and right vertical frames 54L, 54R are inserted into the opening 12a of the frame 12 and fixed to the frame 12 with the first fasteners 40 in the first step (see FIG. 11A). Next, the upper frame 55 is inserted between the left and right vertical frames 54L, 54R in the projection direction from the room side toward the inside of the storage unit (see FIG. 11A and FIG. 12A). Then, the sighting surface 28b of the upper frame 55 is abutted against the sighting surfaces of the first sighting parts 21 of the left and right vertical frames 54L, 54R in the third step (see FIG. 11B and FIG. 12B).

[0053] In this way, even in the door and window frame 50, the upper frame 55 can be easily positioned in the projection direction relative to the vertical frames 54 by simply inserting it between the left and right vertical frames 54L, 54R and butting its sight surface 28b against the first sight portion 21, facilitating assembly work. Finally, the fourth step is performed in which the upper frame 155 is fixed to the frame 12 with the second fixing device 41, and the guide rail portion 28 is further fixed to the frame 12 with the fixing device 64.

[0054] This completes the installation work of the fitting frame 50 to the skeleton 12. This installation method also makes it easy to individually fix the vertical frame 54 and the upper frame 55 to the skeleton 12. The lower frame 56 may be fixed to the floor 66, for example, before or after the installation process of the upper frame 55.

[0055] In this type of fitting frame 50, the projection portion 30b of the upper frame 55 is disposed perpendicular to the projection piece 60 of the vertical frame 54, forming a corner portion C between them. Therefore, the fitting frame 50 can also ensure the quality of its appearance when viewed from the inside of the frame or the inside of the room.

[0056] Also, in the case of the configuration example shown in FIG. 9 and FIG. 10, after the fitting frame 50 is fixed to the frame 12, the wall panel 42 is appropriately attached around it. In this embodiment, the wall panel 42 is attached to the upper frame 55 so as to cover and hide the frame 12 and the rail holding part 62a from the room side while abutting against the frame outer projection surface of the projection part 30b. The wall panel 42 is attached to the upper frame 55 so as to abut against the upper part of the visible surface 28b. The wall panel 42 is attached to the vertical frame 54 so as to cover and hide the frame 12 and the hollow part of the vertical frame 54 from the room side while abutting against the frame outer projection surface of the projection piece 60. The wall panel 42 is attached to the vertical frame 54 so as to abut against the frame outer projection surface of the visible part 59. As a result, when viewed from the indoor side and the interior side of the storage space, most of the fitting frame 50 is covered and hidden by the wall panel 42, and the exposed portion is extremely narrow, resulting in a high appearance quality.

[0057] The fitting frame according to the first aspect of the present invention is a fitting frame to be attached to an opening provided in the skeleton of a building, and includes left and right vertical frames fixed to the skeleton with a first fastener, and an upper frame fixed to the skeleton with a second fastener and provided between the left and right vertical frames, the vertical frames have a first sighting portion extending from one side of the sighting surface in the sight direction to the inner periphery, and the upper frame has a first sighting surface on one side in the sight direction abutting the first sighting portion of the vertical frame. In this way, the fitting frame is provided with a first sighting portion on the vertical frame that positions the upper frame in the sight direction, making it possible to separately and easily fix the vertical frame and the upper frame to the skeleton.

[0058] The vertical frame may have a groove formed by the projection surface, the first projection portion, and a second projection portion extending inward from the other of the projection surfaces in the projection direction, a notch portion provided at the upper end of the second projection portion, the upper frame may have protrusions at both ends in the longitudinal direction that fit into the groove portion, and when the protrusions are fitted into the groove portion, the first projection surface on one side abuts against the first projection portion of the vertical frame in the projection direction. In this way, by providing a notch portion at the upper end of the second projection portion of the groove portion of the vertical frame, when the upper frame is inserted between the left and right vertical frames, the upper frame can be fixed to the frame more smoothly, and interference between the frames can be suppressed.

[0059] The upper frame may be configured so that, with the protrusion housed in the groove, a second sight surface on the other side in the projection direction is disposed in the notch, thereby complementing the second sight portion of the vertical frame. In this way, after the fitting frame is fixed to the framework, the notch is prevented from being conspicuous in appearance.

[0060] The second visible portion of the vertical frame has a first portion that becomes a side wall of the groove portion, and a second portion that protrudes from the first portion in a first direction away from the groove portion in a visible direction and forms a visible surface of the vertical frame, and the upper frame has a visible portion that protrudes in the first direction from a position set back from the tip surface of the protruding portion on the second visible surface and forms the visible surface of the upper frame, and the visible portion may be arranged perpendicular to the second portion and form a corner portion between the second portion. In this way, the appearance quality of the door and window frame is improved when viewed from the inside of the frame or from the front side.

[0061] The upper frame has a guide rail section for slidably guiding the shoji screen supported by the door frame, a first attachment that is detachably attached to the visible surface on one side in the projection direction of the guide rail section and abuts against the visible surface of the vertical frame when the protrusion is housed in the groove, and a second attachment that is detachably attached to the visible surface on the other side in the projection direction of the guide rail section and abuts against the visible surface of the vertical frame when the protrusion is housed in the groove and is provided with the projection, and the protrusion may be composed of the guide rail section and the second attachment, and a part of the second attachment may be placed in the cutout when the protrusion is housed in the groove to complement the second visible portion of the vertical frame. In this way, high versatility can be obtained by the upper frame being composed of multiple attachment parts.

[0062] The method for mounting a door frame according to the second aspect of the present invention is a method for mounting a door frame to an opening provided in a building framework, comprising: a first step of fixing the left and right vertical frames to the opening; a second step of passing the upper frame in the projection direction through a notch formed at the upper end of the second projection of the vertical frame after the first step; a third step of positioning the upper frame in the projection direction relative to the vertical frame by abutting the projection surface on the leading side against the first projection in the moving direction of the projection; and a fourth step of fixing the upper frame to the opening after the third step. According to this method, the work of fixing the vertical frame and the upper frame to the framework can be easily performed separately.

[0063] It should be noted that the present invention is not limited to the above-described embodiment, and can of course be freely modified without departing from the spirit and scope of the present invention. [Explanation of symbols]
