Description

[Technical field]

[0001] The present invention relates to a mounting structure for fittings. [Background technology]

[0002] A typical sliding door is slidably guided by an upper frame and a lower frame, and closes the space between the first and second chambers in the closed position and opens the space in the open position. A sleeve wall is provided to separate the first and second chambers at a position facing the sliding door in the open position (see Patent Document 1). The first floor material forming the floor of the first chamber and the second floor material forming the floor of the second chamber may differ in color, pattern, texture, gloss, etc. (hereinafter referred to as color, etc.).

[0003] [Patent Document 1] JP 2005-226313 A Summary of the Invention [Problem to be solved by the invention]

[0004] The sleeve wall is positioned offset from the sill to the first or second chamber depending on the thickness of the sliding door, so there is some space between the sleeve wall and the sill. Here, we will assume that the sleeve wall is positioned offset from the sill to the second chamber.

[0005] In building construction, the first floor in the first room and the second floor in the second room may be separated by a sill, and the second floor is installed in the space between the sleeve wall and the sill. This space is not visible from the second room, and is not visible when the sliding door is in the open position.

[0006] However, this space is visible from the first room when the sliding door is in the closed position. Therefore, in the first room, both the first floor material and the second floor material are visible across the bottom frame, which gives the user a sense of incongruity and is not desirable from a design perspective. Although it is technically possible to provide the first floor material in this relatively narrow space, it is not desirable from a construction perspective to provide a small piece of the first floor material separately from the large first floor material.

[0007] The present invention has been made in consideration of the above problems, and has an object to provide a mounting structure for fittings that has excellent design. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems and achieve the objective, the mounting structure of the fittings of the present invention is a fitting equipped with a sliding door that is movably arranged via a bottom frame on one side of a sleeve wall, and is characterized in having a trim material in an area including between the bottom frame and the sleeve wall. Effect of the Invention

[0009] The fitting mounting structure of the present invention is not restricted by the first and second spaces separated by the sleeve wall, allowing for freedom of choice and excellent design. [Brief description of the drawings]

[0011] An embodiment of the fitting mounting structure (hereinafter, simply referred to as the mounting structure) according to the present invention will be described in detail below with reference to the drawings. Note that the present invention is not limited to this embodiment. The fitting 10, which is the subject of the mounting structure according to the embodiment of the present invention, is provided in a position that separates a first space (one side of the sleeve wall 16) and a second space (the other side of the sleeve wall 16) inside a building. The first space and the second space are, for example, a room, a corridor, a lobby, etc.

[0012] Fig. 1 is a front view of a fitting 10, which is the target of a mounting structure according to an embodiment of the present invention, as viewed from a first space. Fig. 2 is a cross-sectional view of the fitting 10 with the sliding door 14 closed. Fig. 3 is a cross-sectional view of the fitting 10 with the sliding door 14 open. Fig. 4 is a vertical cross-sectional view taken along line IV-IV in Fig. 3. Fig. 5 is a vertical cross-sectional view taken along line V-V in Fig. 2.

[0013] The fitting 10 is provided with a sliding door 14 that is movably arranged on one side of the sleeve wall 16 via a bottom frame 22. In the mounting structure of the fitting 10, a trim member 20 is provided at a location including between the bottom frame 22 and the sleeve wall 16. The bottom frame 22 is a part of the frame body 12. The sleeve wall 16 is provided with a center mullion 18. The frame body 12 is a framed structure of the bottom frame 22, the top frame 24, the end frame 26, and the front frame 28 on all four sides. The four frame members are fixed to the framework 34 and the floor base material 30 with screws, nails, or the like. These four frame members do not necessarily have to be fixed to each other, and only need to have an approximate frame shape in appearance. The bottom frame 22, the top frame 24, the end frame 26, the front frame 28, and the center mullion 18 are extruded members formed from metal such as aluminum alloy, and are configured to have a substantially uniform cross section along the entire length. The frame 12 may be covered by a wall panel or the like and barely visible, but is explicitly shown in FIG. 1 as having a moderate width.

[0014] In this application, the prospective direction refers to the direction from the first space to the second space in the fitting 10 (the direction perpendicular to the paper in FIG. 1). The prospective surface refers to a surface extending along the prospective direction. The prospective direction refers to a direction perpendicular to the prospective direction, and in the case of the door end vertical frame 28 that is long in the vertical direction, it refers to the left-right direction perpendicular to the longitudinal direction, and in the case of the bottom frame 22 that is long in the horizontal direction, it refers to the up-down direction perpendicular to the longitudinal direction. The prospective surface refers to a surface along the prospective direction. The inside (inner circumference side) of the frame-shaped member refers to, for example, the inner frame part of the frame body 12. The outside (outer circumference side) of the frame-shaped member refers to, for example, the outer frame part of the frame body 12. These names are applied not only to the frame body 12 but also to other related components such as the sliding door 14, the sleeve wall 16, and the trim material 20.

[0015] The sliding door 14 is guided by the lower frame 22 and the upper frame 24 so as to be slidable in the left-right direction in FIG. 1. The sliding door 14 has a handle fitting 14a, which is operated by placing a hand on it to slide between a closed position and an open position. In the closed position (see FIG. 2), the sliding door 14 abuts the vicinity of the door end 14b against the vertical door end frame 28 and overlaps with the center mullion 18 at the door end 14b, thereby closing the first space and the second space. The sliding door 14 in FIG. 1 is in the closed position. In the open position (see FIG. 3), the sliding door 14 abuts the vertical door end frame 26 and overlaps with the center mullion 18 at the door end 14b, thereby opening the first space and the second space. In other words, when the sliding door 14 is in the open position, the rectangular area surrounded by the bottom frame 22, top frame 24, door end vertical frame 28, and the door end of the sliding door 14 becomes the open passage 32. As can be seen from Figures 2 and 3, the visible surface of the center mullion 18 on the first space side is always covered by the sliding door 14 and is hardly visible. This visible surface is provided with mohair 18a. The sliding door 14 is a single shoji screen, but multiple shoji screens may be configured to be able to slide in pairs. The door end vertical frame 26 is provided on the door end side of the sliding door 14, but if a sliding door is left open, the door end of the sliding door 14 may not abut against the door end vertical frame 26.

[0016] The sleeve wall 16 is provided in a position facing the sliding door 14 in the open position, and separates the first space from the second space. In other words, when the sliding door 14 is in the closed position, the fitting 10 separates the first space from the second space by the sliding door 14 and the sleeve wall 16. The end of the sleeve wall 16 abuts against the building frame 34, and a mullion 18 is provided on the first space side of the door tip.

[0017] The sleeve wall 16 has a sleeve wall base material 16a which is a main part, a wall panel 16b which covers the surface of the sleeve wall base material 16a facing the first space, and a wall panel 16c which covers the surface facing the second space. The sleeve wall base material 16a is a structure assembled from, for example, pillars, studs, and furring strips. A wall panel 16d is provided on the side end surface of the opening passage 32 of the sleeve wall 16. The wall panels 16b to 16d are, for example, gypsum boards. Wallpaper may be applied to each surface of the wall panels 16b to 16d. A baseboard 35 is applied to the lower ends of the wall panels 16b and 16c. The baseboard 35 may be omitted. Reference numeral 37 denotes a corner member.

[0018] FIG. 6 is an enlarged view of the lower part of FIG. 4. The lower frame 22 has a central part 22a fixed to the floor underlayment 30 with screws, fin parts 22ba, 22bb protruding from the left and right upper ends of the central part 22a toward the first space side and the second space side to form an inner peripheral side visible surface, and a rail member 22c fitted into the central part 22a. The cross section of the central part 22a is a U-shape opening upward. The lower frame 22 has a symmetrical shape, but the fin part 22ba protrudes toward the second space side and the fin part 22bb protrudes toward the first space side. The tips of the fin parts 22ba, 22bb are smoothly inclined downward. The height H of the tips of the fin parts 22ba, 22bb based on the floor underlayment 30 is the standard value for general floor materials. Since the lower frame 22 has a symmetrical shape, it is possible to install it with the left and right sides reversed.

[0019] The rail member 22c guides the roller 14d protruding from the lower surface of the sliding door 14, and covers the screw screwed into the central portion 22a. The rail member 22c is separate from the central portion 22a, but may be an integral structure depending on the design conditions.

[0020] The floor of the area of ​​the first space on the opposite side of the sleeve wall 16 (the right side in FIG. 6) with the bottom frame 22 as a boundary is formed by a first floor material 36 provided on the floor underlayment 30. The floor of the second space is formed by a second floor material 38 provided on the floor underlayment 30. The first floor material 36 and the second floor material 38 are, for example, wood (including plywood, laminated wood, etc.) and have a thickness of H. The first floor material 36 and the second floor material 38 are different in color, etc. Note that the first floor material 36 and the second floor material 38 are provided at least near the fitting 10, but the entire surface of the right side of the bottom frame 22 in the first space does not need to be the first floor material 36, and similarly, the entire surface of the floor of the second space does not need to be the second floor material 38.

[0021] The first floor material 36 extends below the fin portion 22bb, but in consideration of dimensional errors and ease of construction, a small gap G1 is provided between the first floor material 36 and the central portion 22a as a margin. The first floor material 36 extends below the fin portion 22bb, and is sandwiched between the fin portion 22bb and the floor underlayment 30.

[0022] The sleeve wall base material 16a of the sleeve wall 16 is provided so as to rest on the upper surface of the floor base material 30. The end face of the second floor material 38 abuts the visible surface of the sleeve wall base material 16a. The wall plate 16c is provided so as to rest on the upper surface of the second floor material 38. In other words, the second floor material 38 extends below the wall plate 16c and is sandwiched between the wall plate 16c and the floor base material 30, so that no gap is generated between the second floor material 38 and the sleeve wall 16. The edge 38b (see FIG. 7) of the second floor material 38 on the first space side in the opening passage 32 extends below the fin portion 22ba of the lower frame 22.

[0023] The trim material 20 is provided on the floor base material 30 in a location including between the bottom frame 22 and the sleeve wall 16. In other words, the trim material 20 is provided at least from the edge L1 on the second space side of the bottom frame 22 to the edge L2 on the first space side of the sleeve wall 16, and may include a case where a part of the trim material 20 overlaps with the bottom frame 22 or the sleeve wall 16 in a plan view. The trim material 20 forms the floor of the area A on the sleeve wall side (left side of FIG. 6) with the bottom frame 22 in the first space as the boundary. In this application, one side (right side of FIG. 6) with the sleeve wall 16 as the boundary is called the first space, and the other side (left side of FIG. 6) is called the second space, but this is merely an expression for convenience of explanation, and the area A where the trim material 20 forms the floor can also be called the third space or intermediate space.

[0024] The trim material 20 is different from the first floor material 36 and the second floor material 38, but may be made of a material of a similar color to the first floor material 36. The trim material 20 in this embodiment is an extruded material made of a metal such as an aluminum alloy, and is configured to have a substantially uniform cross section over the entire length along the longitudinal direction.

[0025] The trim material 20 is made of the same material as the fin portions 22ba, 22bb of the lower frame 22, and also has the same color, etc. The trim material 20 is rectangular tubular, with the short side of the rectangle running vertically and the long side running horizontally. The trim material 20 is fixed to the floor underlayment material 30 with adhesive tape or the like. Since the trim material 20 has a rectangular tubular shape, it may be applied upside down. The trim material 20 is made of a rectangular tubular metal material, which makes it lightweight yet provides sufficient strength, and it can reliably support the wall panel 16b (described later) even if it is somewhat heavy, and it is less likely to deform over time.

[0026] The height H1 of the parting material 20 is equal to or slightly lower than the height H of the first floor material 36 and the second floor material 38, but is substantially equal to the height H. By making the height H1 of the parting material 20 slightly lower than the height H, the edge 20b (see FIG. 7) on the open passage 32 side is not visible.

[0027] Part of the upper surface 20a of the trim material 20 is exposed, and forms the floor of area A on the sleeve wall 16 side (left side in FIG. 6) with the lower frame 22 in the first space as the boundary. Area A is the portion sandwiched between the edge L1 on the second space side of the lower frame 22 (i.e., the edge on the second space side of the fin portion 22ba) and the edge L2 on the first space side of the lower end of the wall panel 16b. The projected dimension of the trim material 20 is sufficiently larger than the width of area A.

[0028] As described above, conventionally, in terms of building construction, the first floor material 36 and the second floor material 38 may be separated by the sill 22, and the second floor material 38 may be attached to the area A between the sleeve wall 16 and the sill 22. However, this area A is visible from the first space when the sliding door 14 is in the closed position, and there is a concern that both the first floor material 36 and the second floor material 38 are visible with the sill 22 as the boundary, giving the user a sense of discomfort.

[0029] In contrast, in the fitting 10, the floor in area A is formed by a trim material 20 different from the first floor material 36 and the second floor material 38, so the user does not feel uncomfortable, and there is a degree of freedom in selecting colors, etc., while ensuring design consistency with the adjacent sill 22 in the projection direction, resulting in an excellent design. This selection should be made based on the designer's judgment and the user's requests.

[0030] It is preferable that at least the upper surface 20a (in other words, the inner peripheral visible surface) forming the floor of the trim material 20 is the same color as the fin portions 22ba, 22bb of the lower frame 22, so that a sense of unity with the lower frame 22 can be achieved in terms of design. Note that the term "same color" does not have a strict meaning, but rather it is sufficient that the color is perceived as substantially the same color by a user passing through the open passage 32. By using the same material and color settings for the trim material 20 and the lower frame 22, a greater sense of unity can be achieved, and the design can be further improved.

[0031] Also, although it is possible to provide the first floor material 36 in the area A, it is not preferable from the viewpoint of construction to separately prepare the first floor material 36 as a dedicated small piece for the narrow area A. Furthermore, applying the first floor material 36 to the area A lacks uniformity in design of the entire building material 10 including the sill 22, and is not necessarily preferable. Therefore, as described above, it is preferable that the trim material 20 is different from the first floor material 36 and the second floor material 38 and is selected separately from the viewpoint of design.

[0032] Furthermore, although it is possible to enlarge the fin portion 22ba of the sill 22 to hide the area A, this requires special processing for each construction object to which it is applied, and the sill 22 has an asymmetric shape, making it impossible to apply it in reverse, which creates construction problems. In the fitting 10, by applying the trim material 20 to the floor of the area A, such inconveniences do not occur.

[0033] The parting material 20 extends below the fin portion 22ba, and no gap is created between them in the front direction. The parting material 20 is sandwiched between the tip of the fin portion 22ba and the floor underlayment material 30, and no gap is created between them in the front direction. This provides a design advantage and prevents foreign objects from being caught between the parting material 20 and the fin portion 22bb.

[0034] In addition, the height H1 of the trim material 20 may be slightly lower than the height H of the first floor material 36, but the tip of the fin portion 22ba can elastically displace slightly up and down and can abut against the upper surface 20a of the trim material 20.

[0035] An appropriate gap G2 is secured between the first space side visible surface of the trim material 20 and the central portion 22a. The projected distance between the sleeve wall 16 and the sill 22 may vary depending on the specifications and construction reasons. Therefore, the width of the area A may also vary, but by securing the gap G2, the difference in the width of the area A can be absorbed (see FIG. 11).

[0036] The trim material 20 penetrates below the wall panel 16b, and no gaps are formed between them in the visible direction. The trim material 20 is sandwiched between the wall panel 16b and the floor underlayment material 30, and no gaps are formed between them in the visible direction. This not only provides a favorable design, but also prevents foreign objects from being caught between the trim material 20 and the wall panel 16b.

[0037] Fig. 7 is an enlarged cross-sectional view of a part of the fitting 10. In Fig. 7, the sliding door 14 is omitted, and the bottom frame 22 is shown by virtual lines. In addition, the area where the first floor material 36 and the second floor material 38 are provided is shown by hatching, and hatching is omitted in the cross sections of other components to avoid complexity. This type of illustrated form is also used in Figs. 8 and 10 described later.

[0038] The trim material 20 extends below the sleeve wall side portion 26a located closer to the sleeve wall 16 than the bottom frame 22 of the end frame 26, so that no gap is created between them in the left-right direction. The trim material 20 is sandwiched between the sleeve wall side portion 26a and the floor underlayment material 30, and no gap is created between them in the vertical direction. This is advantageous in terms of design and prevents foreign objects from being caught between the trim material 20 and the sleeve wall side portion 26a.

[0039] Although the wall panel 16d and the mullion 18 are provided in the vicinity of the fore-edge 20b at the end of the door trailing edge (the right side in FIG. 7) of the trim material 20, the trim material 20 does not have to extend below these. This is because this portion is hidden by the sliding door 14 and is hardly visible.

[0040] The construction of the fitting 10 can take various forms. In the example shown in Figures 6 and 7, the sleeve wall base material 16a of the sleeve wall 16 is constructed, and then the first floor material 36 and the second floor material 38 are laid on the floor. Specifically, the sleeve wall base material 16a is first placed at a predetermined position on the upper surface of the floor base material 30 and fixed in place by a predetermined method.

[0041] Then, a first floor material 36 is attached to a predetermined area of ​​the first space, and a second floor material 38 with a notch 38a is attached to the second space. An edge 38b on the first space side of the second floor material 38 is aligned to a position that ensures an appropriate gap between the visible surface of the center portion 22a of the lower frame 22. This gap is approximately the same as the above-mentioned gap G1 (see FIG. 6).

[0042] The notch 38a is formed of a lateral edge 38aa along the extension direction of the lower frame 22 and a front edge 38ab perpendicular to the lateral edge 38aa. The lateral edge 38aa is formed at a position abutting and running along the lower end of the second space side front surface of the sleeve wall base material 16a. The front edge 38ab is formed at a position abutting and running along the lower end of the front surface of the sleeve wall base material 16a on the opening passage 32 side.

[0043] Thereafter, the trim material 20 is fixed so that its projected surface on the second space side abuts against the sleeve wall base material 16a and its underside abuts against the floor base material 30. Then, the wall panel 16b is fixed so that its projected surface on the second space side abuts against the sleeve wall base material 16a and its underside abuts against the trim material 20. In addition, the wall panels 16c and 16d are fixed so that they abut against the sleeve wall base material 16a and the second floor material 38, respectively. After the wall panels 16b to 16d are installed, the center mullion 18 is provided. Finally, the frame body 12 is fixed and the sliding door 14 is fitted into the lower frame 22 and upper frame 24.

[0044] Fig. 8 is a partially enlarged horizontal cross-sectional view of the fitting 10 constructed by the construction method according to the first modified example. Fig. 9 is a partially enlarged vertical cross-sectional view of the fitting 10 constructed by the construction method according to the first modified example. In the construction method according to the first modified example, the first floor material 36 and the second floor material 38 are laid, and then the sleeve wall base material 16a is constructed. In this case, the horizontal edge 38aa of the notch 38a is formed at a position closer to the first space by the expected width of the sleeve wall base material 16a than in the examples shown in Figs. 6 and 7.

[0045] In the construction method according to the first modification, after the first floor material 36 and the second floor material 38 are attached to the floor base material 30, the sleeve wall base material 16a is placed on the second floor material 38. At this time, the first space side visible surface of the sleeve wall base material 16a is made to be on the same plane as the lateral edge 38aa. Then, the trim material 20 is fixed so that the second space side visible surface abuts against the visible surface of the lateral edge 38aa of the second floor material 38 and the underside abuts against the floor base material 30. Thereafter, the construction of the wall panels 16b to 16d, the frame body 12, etc. is performed according to the above-mentioned procedure.

[0046] Fig. 10 is a partially enlarged cross-sectional view of the fitting 10 constructed by the construction method according to the second modified example. Fig. 11 is a partially enlarged vertical-sectional view of the fitting 10 constructed by the construction method according to the second modified example. In this case, the horizontal edge 38aa of the notch 38a is formed at a position closer to the first space side by about half the width of the wall panel 16b than in the example shown in Figs. 8 and 9.

[0047] In the construction method according to the second modification, after the first floor material 36 and the second floor material 38 are attached to the floor base material 30, the sleeve wall base material 16a is provided on the second floor material 38. At this time, the first space side visible surface of the sleeve wall base material 16a is positioned closer to the second space side than the horizontal edge 38aa by about half the width of the wall panel 16b. Then, the trim material 20 is fixed so that the second space side visible surface abuts against the visible surface of the horizontal edge 38aa of the second floor material 38 and the lower surface abuts against the floor base material 30. Then, the wall panel 16b is fixed so that the second space side visible surface abuts against the sleeve wall base material 16a, and the second space side half of the lower surface abuts against the upper surface of the second floor material 38 and the first space side half abuts against the upper surface of the trim material 20. In this case, the parting material 20 is shifted slightly toward the first space side compared to the above example, but a certain degree of gap G2 with the center portion 22a is secured. The wall panels 16c, 16d, the frame body 12, etc. are installed in accordance with the above procedure.

[0048] As can be seen from the above examples, it is preferable that the sleeve wall base material 16a rests on the upper surface of either the floor base material 30 or the second floor material 38. It is preferable that at least a portion of the wall panel 16b on the first space side rests on the upper surface of the trim material 20. Also, there is basically no gap between the second room side visible surface of the trim material 20 and the sleeve wall base material 16a or the second floor material 38. This is to stabilize the support of the wall panel 16b.

[0049] In each of the above examples, the fixture 10 is provided with a mullion 18, but depending on the design or aesthetic reasons, the mullion 18 may be omitted as shown in Figure 12. In this case, the visible surface of the sleeve wall 16 on the side of the open passage 32 may be provided with corner members 37 at the first space side and second space side ends.

[0050] In the above-mentioned mounting structure of the fitting 10, the trim material 20 is provided in a location including between the bottom frame 22 and the sleeve wall 16, and the floor of the area A on the sleeve wall 16 side of the bottom frame 22 in the first space is formed by the trim material 20, and the opposite side is formed by the first floor material 36. The trim material 20 is different from the first floor material 36 and the second floor material 38, and is not restricted by these first floor material 36 and the second floor material 38, allowing freedom of selection and excellent design and workability. In addition, the trim material 20 is provided in this area A, and the second floor material 38, which should be the floor of the second space, does not extend, so there is no sense of incongruity in the design of the first space including the area A.

[0051] The first floor material 36 and the second floor material 38 may be the same. Even in such a case, by selecting the trim material 20 of an appropriate color, etc., it is possible to create a unified design for the entire fitting 10 including the sill 22. The fitting 10 can be applied to both new building and remodeling of buildings.

[0052] The fitting structure of the present invention is a fitting structure with a sliding door movably arranged via a lower frame on one side of a sleeve wall, and is characterized in that a trim material is provided in a location including between the lower frame and the sleeve wall. This allows for freedom of choice and excellent design without being restricted by the space on one side and the space on the other side of the sleeve wall.

[0053] The fitting structure of the present invention is characterized in that the trim material is provided on the floor underlayment, is different from the first floor material provided on the floor underlayment on one side of the sleeve wall and the second floor material provided on the floor underlayment on the other side of the sleeve wall, and forms the floor of the sleeve wall side area with the lower frame on the one side as a boundary. This eliminates the constraints of the first and second floor materials.

[0054] The fitting structure of the present invention is characterized in that the lower frame has a fin portion that protrudes toward the sleeve wall side to form an inner peripheral side visible surface, and the trim material extends below the fin portion. This prevents a gap from occurring between the trim material and the fin portion.

[0055] The fitting structure of the present invention is characterized in that the trim material extends below the wall panel covering the surface of the sleeve wall, thereby preventing a gap from occurring between the trim material and the sleeve wall base material.

[0056] The fitting structure of the present invention is characterized in that a vertical end frame is provided on the end side of the sliding door, and the trim material extends below the sleeve wall side portion located on the sleeve wall side of the lower frame of the vertical end frame. This prevents a gap from occurring between the trim material and the sleeve wall side portion.

[0057] The fitting mounting structure of the present invention is characterized in that at least the inner peripheral surface of the trim is the same color as the lower frame, thereby allowing the fitting to have a unified design.

[0058] The fitting mounting structure of the present invention is characterized in that the trim material has a rectangular tubular shape, which makes the trim material lightweight and strong.

[0059] 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]
