Mode for Carrying Out the Invention
[0011] The present embodiment will be described in detail with reference to FIGS. 1 to 12. Example
[0012] <Configuration> This example has the following configuration
[0013] As shown in FIG. 1, a building 1 internally includes a movable partition 3 that partitions a living room space 2. The movable partition 3 is movably provided with a partition wall 6 sized to extend from a floor 4 to a ceiling 5.
[0014] Here, the building 1 may be any type such as a detached house or an apartment house. The building 1 may be of any construction type such as wooden construction, steel frame construction, or reinforced concrete construction. In this example, the building 1 is a unit building.
[0015] The living room space 2 is a space that forms a living room inside the building 1. The living room space 2 may be an internal space.
[0016] The movable partition 3 is a facility of the building 1 in which a partition wall 6 for partitioning the living room space 2 is movably installed.
[0017] The floor 4 is a substantially horizontal surface that forms the lower part of the living room space 2.
[0018] The ceiling 5 is a substantially horizontal surface that forms the upper part of the living room space 2. The ceiling 5 includes a ceiling base material 5a and a ceiling surface material 5b.
[0019] The partition wall 6 is a movable wall that constitutes the movable partition 3, and one or more partition walls are used depending on the size required for partitioning the living room space 2.
[0020] Further, the movable partition 3 of this example may have the following configuration.
[0021] (1) As shown in Figure 2 (Figure 2A), a rail 13 is attached to a mounting member 12 fixed to the ceiling surface 11, which guides the partition wall 6 from below. A cover 14 is attached to the side surface 13a of the rail 13, covering the rail 13 and the mounting member 12, and reaching the ceiling surface 11. The mounting member 12 has a recess 16 for holding adhesive 15 that adheres to the upper part of the cover 14.
[0022] Here, the directions are defined as the front-to-back direction X, the width direction Y, and the up-and-down direction Z, with the partition wall 6 as the reference point. The front-to-back direction X is the direction of movement of the partition wall 6 and is the longitudinal direction of the mounting member 12 and the rail 13.
[0023] The ceiling surface 11 is the lower surface of the ceiling 5 (ceiling surface material 5b).
[0024] The mounting member 12 is a wooden or resin member for attaching the rail 13 to the ceiling surface 11. As shown in Figure 3, the mounting member 12 is a long member with a nearly uniform cross-section and is installed continuously and nearly horizontally along the entire length of the rail 13. The top surface of the mounting member 12 is almost entirely fixed to the ceiling surface 11 by adhesive, and as shown in Figures 4 and 5, both ends and the center are fixed to the ceiling surface 11 from below almost perpendicularly by fasteners 17 such as screws or nails. As shown in Figure 6, the mounting member 12 may be divided into multiple sections in the longitudinal direction, or it may be a single piece.
[0025] Furthermore, the mounting member 12 may have a height-adjusting mounting auxiliary member 18 installed on its underside if necessary. The mounting auxiliary member 18 is made of a thin plate of a certain thickness and is appropriately interposed between the mounting member 12 and the rail 13. The mounting auxiliary member 18 is partially installed, for example, at both ends of the rail 13 or where height adjustment is required, and is partially attached to the mounting member 12 from below with a fastener 19 such as a stapler. The mounting auxiliary member 18 is not provided in places where height adjustment is not required (for example, in areas enclosed by dashed lines).
[0026] The partition wall 6 is a movable wall and, as shown in Figure 2, has a suspension wheel 21 at its top for moving along the rail 13. The lower part of the partition wall 6 can be configured in any way.
[0027] The rail 13 is a continuous, elongated guide member that guides the movement of the suspension roller 21 attached to the partition wall 6. The rail 13 is a hollow member made of metal or resin and is installed almost horizontally so as to cover almost the entire range of movement of the partition wall 6. The rail 13 is fixed almost perpendicularly from below to the mounting member 12 by fasteners 22 such as screws or nails at both ends and the center in the longitudinal direction.
[0028] The rail 13 has a substantially rectangular cross-section portion having a pair of side surfaces 13a, an upper surface 13b, and a lower surface 13c, and the roller 21a of the suspension wheel 21 is rotatably housed inside the rectangular cross-section portion. The roller 21a rolls on the lower surface 13c of the rail 13. The rail 13 has an elongated guide slit 13d on its lower surface 13c that extends almost its entire length, through which a connecting member 21b, such as a vertical connecting shaft or connecting plate, passes, connecting the body of the suspension traction unit 21 and the roller 21a. A pair of rollers 21a are provided on both sides of the upper end of the connecting member 21b.
[0029] Note that the rails 13 come in various configurations depending on the number of partition walls 6 installed, including single-track rails with one guide slit 13d and double-track rails with multiple guide slits 13d (two-track, three-track, or more). In this example, we will mainly explain using single-track rails 13, but as shown in Figure 11, double-track rails 13 may also be used in the explanation.
[0030] The side surface 13a of the rail 13 is a vertical surface located on both sides of the rail 13 in the width direction Y. In this example, the side surface 13a of the rail 13 has a downward extension that extends below the bottom surface 13c.
[0031] The cover 14 is a decorative component made of metal or resin, and its main body (cover body) is a vertical surface that mainly conceals at least the upper part of the side surface 13a of the rail 13 (for example, the part above the bottom surface 13c) and the entire mounting member 12. The body of the cover 14 can have any shape, such as having irregularities in the width direction Y, as long as it can conceal at least the upper part of the rail 13 and the entire mounting member 12. For example, as in Patent Document 1, if the width of the mounting member 12 is greater than the width of the rail 13, the cover 14 may have an outward stepped shape where the upper part is located outside the lower part. In this example, the cover 14 has a flat shape (planar) without irregularities in the width direction Y. Furthermore, the cover 14 can be colored or decorated with decorative patterns on its surface.
[0032] The cover 14 is attached to the side surface 13a of the rail 13 by an adhesive material 23 such as double-sided tape or adhesive. The adhesive material 23 is installed on the inner surface of the cover 14 by being applied to or attached to the inner surface of the cover 14. The adhesive material 23 is provided on the cover 14 in the area that comes into contact with the side surface 13a of the rail 13.
[0033] The cover 14 does not need to be attached to parts of the rail 13 and mounting member 12 that are covered by a fixed wall 24 and are not exposed to the outside, as shown in the plan view of Figure 7, but it is attached to parts that are not covered by the fixed wall 24 and are exposed to the outside. The fixed wall 24 can be appropriately provided to serve as a stopper that restricts the range of movement of the partition wall 6, or as a pocket that houses the partition wall 6.
[0034] As shown in Figures 8 to 11, the adhesive 15 is a field-applied, fluid mounting material for fixing the upper part of the cover 14 to the mounting member 12, and is, for example, an elastic adhesive. The adhesive 15 is applied separately from the adhesive material 23 that adheres the upper surface of the mounting member 12 to the ceiling surface 11 and the adhesive material 23 that attaches the cover 14 to the rail 13, etc.
[0035] The recess 16 is formed on the width end 12a of the mounting member 12 and is recessed inward in the width direction Y so that the width of the mounting member 12 becomes narrower. It serves as a marker for the position where the adhesive 15 is applied and as an adhesive reservoir into which the adhesive 15 is filled.
[0036] The recess 16 may be formed at any position on the width end 12a of the mounting member 12 with respect to the vertical direction Z, but in this example, it is formed by cutting out the upper part of the width end 12a on both sides of the mounting member 12 in an L-shape. As a result, the entire cross-section of the mounting member 12, including the recess 16, becomes convex. The recess 16 may also be provided continuously along the entire length of the mounting member 12 in the longitudinal direction. As a result, the mounting member 12 becomes a member with a uniform cross-section along its entire length. It is also possible to provide the recess 16 only in necessary locations, such as both ends, the center, or the middle of the mounting member 12 in the longitudinal direction.
[0037] (2) As shown in Figure 2 (Figure 2A), in the movable partition 3, The cover 14 may have a lateral surface portion 31 at its upper end that extends toward the mounting member 12 and makes surface contact with the ceiling surface 11. The mounting member 12 may have its width end 12a positioned between the tip 31a of the side surface 31 and the side surface 13a of the rail 13 with respect to the width direction Y. Furthermore, the tip portion 31a of the lateral portion 31 may be inserted into the interior of the recess 16.
[0038] Here, the upper end of cover 14 is the upper end of the cover body. The cover body is the main part of cover 14, extending in the vertical direction Z.
[0039] The side surface portion 31 is a portion that extends laterally along the ceiling surface 11 for a required length, inward in the width direction Y from the upper end of the cover body. The space between the cover body and the side surface portion 31 is a bent portion. The side surface portion 31 has the function of positioning the cover 14 in the vertical direction Z and setting the angle of the cover 14 relative to the ceiling surface 11. The side surface portion 31 is formed to the required angle and length in order to perform the above functions. In this example, the side surface portion 31 extends approximately perpendicular to the cover body and has a length of about 4 mm to 7 mm. The side surface portion 31 may extend with a uniform width along the entire length of the cover 14 in the longitudinal direction, or it may be provided with a uniform width only in the necessary places.
[0040] The width end 12a is the surface located at the end of the mounting member 12 in the width direction Y, and is the surface (side surface) facing the rail 13. The width end 12a of the mounting member 12 is approximately parallel to the side surface 13a of the rail 13. The portion of the width end 12a other than the recess 16 is located between the tip 31a of the side surface 31 and the side surface 13a of the rail 13 with respect to the width direction Y. The recess 16 has a dimension in the vertical direction Z that is larger than the thickness of the side surface 31 so as not to interfere with the side surface 31.
[0041] The distance between the width ends 12a on both sides of the mounting member 12 becomes the width dimension of the mounting member 12. The width ends 12a of the mounting member 12 are set to be approximately 1.0 mm to 2.0 mm (about 1.5 mm in this example) inward from the side surface 13a of the rail 13. As a result, the mounting member 12 is slightly narrower than the rail 13 (for example, by the thickness of the rail 13) and has a width that approximates the width of the rail 13 (approximate width), and is slightly separated from the cover 14.
[0042] The tip portion 31a is the end of the side surface portion 31 that is opposite to the cover body. The tip portion 31a is set to a length of approximately 1.3 mm to 2.3 mm (about 1.8 mm in this example) so that it does not abut against the back of the recess 16.
[0043] Furthermore, the gap between the tip 31a of the side surface 31 and the back of the recess 16 is set to be narrow. Therefore, if a misalignment occurs in the width direction Y between the mounting member 12 and the rail 13, on one side in the width direction Y, the tip 31a of the side surface 31 will abut against the back of the recess 16, while on the other side, the gap between the tip 31a of the side surface 31 and the back of the recess 16 will be too large. This misalignment will cause unevenness in the adhesion of the cover 14 to the rail 13. Therefore, high precision in the width direction Y is required when attaching the rail 13 to the mounting member 12.
[0044] (3) In the movable partition 3 described above, as shown in Figure 2A, the side surface 31 may be provided with a claw portion 41 at its tip portion 31a.
[0045] Here, the claw portion 41 is integrally formed with the side surface portion 31, with the tip portion 31a of the side surface portion 31 being a part that bulges downward relative to the rest of the side surface portion 31. The claw portion 41 has a tapered portion (tip portion 41a) to facilitate insertion into the recess 16, and a downward-sloping portion (hook portion 41b) to prevent it from coming out by catching on the adhesive 15 that has hardened inside the recess 16. The tip portion 41a has a gently sloping surface, and the hook portion 41b has a steeply sloping surface.
[0046] In this example, the tip portion 31a has a nearly constant thickness of approximately 1 / 3 of the vertical dimension of the recess 16, except for the portion excluding the claw portion 41. The claw portion 41 has a thickness of approximately 1 / 2 of the vertical dimension of the recess 16 at the boundary between the widest part, the tip portion 41a, and the hook portion 41b.
[0047] <Effect> The effect of this embodiment is as follows:
[0048] First, I will explain the procedure for installing the movable partition 3.
[0049] The mounting member 12 is attached to the ceiling surface 11 from below by applying adhesive to the entire upper surface, excluding the recess 16. Furthermore, as shown in Figures 4 and 5, at least both ends of the mounting member 12 are fixed to the ceiling surface 11 from below by fasteners 17 such as screws or nails. If the mounting member 12 is long, the central or intermediate portion of the mounting member 12 may also be fixed to the ceiling surface 11 from below by fasteners 17.
[0050] Furthermore, if necessary, mounting support members 18 may be installed on the lower sides of both ends of the mounting member 12, as shown in Figure 6.
[0051] Then, the rail 13 is attached to the mounting member 12 from below. The rail 13 is attached to the mounting member 12 and the ceiling surface 11 from below at least both ends using fasteners 17 such as screws or nails. If the rail 13 is long, the middle part of the rail 13 may also be fixed to the mounting member 12 and the ceiling surface 11 from below using fasteners 17. In this case, since the mounting member 12 is approximately the same width as the rail 13, it is easy to visually inspect the mounting member 12 from the outside and touch it with a finger, so the rail 13 can be attached to the mounting member 12 while actually checking the mounting member 12.
[0052] Next, as shown in Figures 8 to 11, the adhesive 15 is injected into the recess 16 at the top of the width end 12a of the mounting member 12. It is most preferable to fill the recess 16 with the adhesive 15 so that it fits snugly, as shown in Figure 10. If necessary, the adhesive 15 may be filled so that it overflows from the recess 16.
[0053] Then, as shown in Figure 11, the cover 14 is attached to the side surface 13a of the rail 13 from the side by peeling off the release paper of the double-sided tape that has been pre-applied to the cover 14 as an adhesive material 23.
[0054] At this time, the side surface 31 at the upper end of the cover 14 is pressed against the ceiling surface 11 so that it makes surface contact with the ceiling surface 11. Also, the side surface 31 of the cover 14 is inserted into the recess 16 and fixed in place by the adhesive 15 filled in the recess 16.
[0055] As described above, the rail 13 is attached to the ceiling surface 11, and the rail 13 and mounting member 12 are covered by the cover 14. By attaching the partition wall 6 to the rail 13, the movable partition 3 is installed.
[0056] In this case, as shown in the comparative example in Figure 12, the mounting member 52 is made so that its width is significantly smaller than the width of the rail 13, and the side surface 52a of the mounting member 52 is positioned inward in the width direction Y from the tip 31a of the side surface 31. In this case, it becomes difficult to visually inspect or touch the mounting member 12 from the outside during installation, so the attachment of the rail 13 to the mounting member 52 becomes a blind operation where the mounting member 52 cannot be seen.
[0057] This makes it easier for misalignment in the width direction Y to occur between the mounting member 52 and the rail 13. As a result, unevenness in the adhesion of the cover 14 to the rail 13 by the adhesive material 23 such as double-sided tape occurs, and even if the adhesive strength of the adhesive material 23 such as double-sided tape is sufficient, there is a risk that peeling may occur in areas where the adhesion has weakened due to aging.
[0058] In contrast, in this example, by making the width of the mounting member 12 approximately the same as the width of the rail 13, the mounting member 12 can be visually inspected and touched from the outside. Therefore, the installation of the rail 13 onto the mounting member 12 becomes a visual operation while actually confirming the position of the mounting member 12. Furthermore, it becomes easier to confirm the position of the rail 13 after it has been installed on the mounting member 12.
[0059] Therefore, misalignment of the rail 13 in the width direction Y relative to the mounting member 12 becomes easier to prevent, and the cover 14 can be attached evenly and stably along its entire length to the side surface 13a of the rail 13. Thus, the cover 14 can be prevented from peeling off due to deterioration over time.
[0060] Furthermore, the upper part of the cover 14 is fixed to the mounting member 12 by adhesive 15. That is, the side portion 31 of the cover 14 is inserted into the recess 16 and fixed by the adhesive 15 filled in the recess 16. In this way, the upper part of the cover 14 is fixed to the mounting member 12, separate from the attachment of the cover 14 to the side surface 13a of the rail 13 using adhesive material 23 such as double-sided tape. This makes the attachment of the cover 14 to the side surface 13a of the rail 13 more stable, and even if the cover 14 peels off from the side surface 13a of the rail 13 due to deterioration over time, the cover 14 will not fall off.
[0061] <Effects> The effects of this embodiment are as follows:
[0062] (Effect 1) The mounting member 12 has a recess 16. By accumulating adhesive 15 in the recess 16, the upper part of the cover 14 is firmly bonded and fixed to the rail 13 by the adhesive 15 in the recess 16, separate from the attachment of the cover 14 to the rail 13. That is, the cover 14 is fixed to the mounting member 12 and the rail 13 at two points, the upper and lower parts. The upper part of the cover 14 is fixed by the adhesive 15 with a fixing strength almost the same as that of mechanical fixing. This fixing of the upper part determines the positional relationship of the cover 14 in the width direction Y with respect to the rail 13, so the attachment state of the cover 14 to the rail 13 is stabilized and the cover 14 is less likely to peel off the rail 13. Furthermore, even if all or part of the cover 14 peels off the rail 13 or becomes prone to peeling off due to deterioration over time, the upper fixing prevents the cover 14 from falling off. Therefore, even when the cover 14 is attached to the side surface 13a of the rail 13, the cover 14 is prevented from peeling off the rail 13.
[0063] (Effect 2) The cover 14 has its upper end side surface 31 in surface contact with the ceiling surface 11. This allows the cover 14 to be installed accurately in the correct position in the vertical direction Z and at the correct angle (for example, perpendicular to the surface) with respect to the ceiling surface 11.
[0064] The mounting member 12 has its width end 12a positioned between the tip 31a of the side surface 31 and the side surface 13a of the rail 13, with respect to the width direction Y. As a result, the mounting member 12 is slightly narrower than the rail 13, and has a width that approximates the width of the rail 13 (approximate width). That is, the width end 12a of the mounting member 12 is close to the position of the side surface 13a of the rail 13. Therefore, during installation, the mounting member 12 can be easily visually inspected from the outside and touched with a finger, allowing the rail 13 to be attached to the mounting member 12 while actually checking the mounting member 12. As a result, the rail 13 can be installed on the mounting member 12 without any misalignment in the width direction Y, improving the mounting accuracy of the mounting member 12 and the rail 13 in the width direction Y. Furthermore, by eliminating or reducing the misalignment of the rail 13 on the mounting member 12 in the width direction Y, it becomes possible to firmly attach the cover 14 to the side surface 13a of the rail 13 along its entire length. Therefore, the cover 14 can be prevented from peeling off.
[0065] The tip 31a of the upper end of the cover 14's side surface 31 is inserted into the recess 16 of the mounting member 12, which is formed to be approximately the same width as the rail 13. This prevents the side surface 31 from interfering with the mounting member 12 and ensures that it is securely fixed by the adhesive 15. Therefore, the side surface 31 can be formed to the length necessary for positioning and angling in the vertical Z direction by surface contact with the ceiling surface 11, and can contribute to fixing the upper part of the rail 13.
[0066] (Effect 3) In the movable partition 3, the side surface 31 may have a claw portion 41 at its tip 31a. This makes it easier for the claw portion 41 to be inserted into the recess 16 and prevents it from coming out by biting into the adhesive 15 that has hardened inside the recess 16.
