Description

[Technical Field]

[0001] The present invention relates to a mounting member. [Background technology]

[0002] Conventionally, techniques for inserting linear members such as wiring or piping through through holes provided in planar members extending along a predetermined plane, such as the ceiling or wall of a building, have been known. For example, Patent Document 1 describes a compartment penetration treatment kit that has a through hole for passing the linear member through and that attaches the fireproofed member to a deck plate, which is a planar member extending along a predetermined plane. This compartment penetration treatment kit includes a formwork having a flange attached to the deck plate and a frame body extending from the flange in a direction opposite the deck plate and surrounding the member, and a buffer material provided inside the frame body.

[0003] In the compartment penetration treatment kit described in Patent Document 1, in order to prevent the spread of fire through the through hole in the event of a fire, the gap between the inner surface of the through hole and the outer surface of the inserted object is blocked with a buffer material. Specifically, in Patent Document 1, one longitudinal side of the buffer material is fixed to the periphery of the formwork with adhesive tape, screws, etc., and the other longitudinal side of the buffer material is fixed to the buffer material with adhesive tape, screws, etc. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2019-100148 Summary of the Invention [Problem to be solved by the invention]

[0005] In some cases, a linear member is attached to a planar member having a through hole while maintaining airtightness between the planar member and the linear member, such as when a through hole is provided in the interior wall substrate of a building and an electric wire is inserted through the through hole.

[0006] In this case, as disclosed in the above-mentioned Patent Document 1, it is conceivable to ensure airtightness between the planar member and the linear member by sealing the gap between the inner surface of the through hole and the outer surface of the linear member with a buffer material using adhesive tape, screws, etc. However, when using such a method, the worker must perform tedious tasks such as applying adhesive tape and fastening screws, which results in poor work efficiency. In particular, in a situation where multiple linear members must be attached to a planar member, the method disclosed in the above-mentioned Patent Document 1 requires the worker to individually perform tasks to ensure airtightness for each linear member constituting the multiple linear members, resulting in very poor work efficiency.

[0007] An object of the present invention is to provide an attachment member that can improve the efficiency of the work of attaching multiple linear members to a planar member while ensuring airtightness between the planar member and the linear members. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, the present invention provides an attachment member for airtightly attaching the linear members inserted into the through holes to a planar member that is provided with one or more through holes for passing a plurality of linear members and that extends along a predetermined plane, the attachment member including an attachment portion that is airtightly attached to a region surrounding the through hole in the planar member, and a peripheral wall that extends from the attachment portion in a first direction opposite to the planar member and surrounds the periphery of the linear members that have passed through the through holes with an axis extending along the first direction as its center; The object of the present invention is to provide an attachment member comprising: a tubular member capable of forming an airtight state with respect to a wall and supported on the peripheral wall so as to be rotatable about the axis; an enclosing portion airtightly attached to the tubular member and surrounding the linear member from the outside; and a partition portion that divides the internal space within the enclosing portion into a plurality of chambers for inserting each of the linear members, and sealing means configured so that, as the tubular member is rotated, the partition portion becomes entangled with the linear member and reduces the internal space of the enclosing portion, and the enclosing portion becomes wrapped around the linear member.

[0009] According to the present invention, since the mounting member has the sealing means, the partition section entangles with the linear member in response to rotation of the tubular member, reducing the internal space of the enclosing section and winding the enclosing section around the linear member. According to this aspect, by rotating the tubular member by a predetermined angle or more, the sealing means can close gaps in each chamber through which the linear member of the partition section passes.

[0010] In addition, in the present invention, the mounting member is attached to the planar member in an airtight manner, the peripheral wall supports the tubular member in an airtight manner, and the surrounding portion is attached to the tubular member in an airtight manner. In this way, in the present invention, the mounting member is configured so that the airtightness of each of the linear members constituting the multiple linear members relative to the planar member is ensured collectively by performing a simple operation such as rotating the tubular member. Therefore, the mounting member of the present invention improves the efficiency of the work of attaching multiple linear members to the planar member while ensuring airtightness between them.

[0011] In the mounting member, it is preferable that the partition portion has the property of compressing and deforming so that the wall portions separating the multiple rooms become thinner when the surrounding portion is subjected to an external force in a direction that reduces the internal space of the surrounding portion.

[0012] According to this aspect, as the surrounding portion is wound around the linear member, the partition portion can flexibly fill gaps between the linear members and gaps between the linear member and the surrounding portion.

[0013] In the attachment member, the partitioning portion is preferably formed by a plurality of fibers intertwined with each other and is provided so as to close the internal space of the surrounding portion.

[0014] According to this aspect, by rotating the tubular member, the plurality of fibers can be entangled with the plurality of linear members while filling gaps between the linear members and gaps between the linear members and the surrounding portion. Furthermore, when the tubular member is rotated, the plurality of fibers are compressed between the linear members and between the surrounding portion and the linear members, thereby increasing the density of the plurality of fibers per unit area. Therefore, by rotating the tubular member by a predetermined angle or more, airtightness between the planar member and the plurality of linear members can be ensured.

[0015] The attachment member preferably has a holding mechanism that holds fibers by entangling them around the entire periphery of the inner surface of the surrounding portion.

[0016] According to this aspect, the partition portion formed of a plurality of fibers can be entangled and held by the holding mechanism, which makes it easier to attach the partition portion to the surrounding portion compared to attaching the partition portion to the surrounding portion using an adhesive or the like.

[0017] Furthermore, when the partitioning section is attached to the surrounding section using adhesive or the like, there is a risk that the adhesive-applied portion of the partitioning section will separate from the remaining portions, causing the partitioning section to come off the surrounding section. In contrast, when the holding mechanism holds the partitioning section by entangling fibers, the attachment state between the surrounding section and the partitioning section can be stabilized.

[0018] The internal space of the surrounding part includes spaces between the linear members and spaces enclosed by the linear members and the surrounding part. Airtightness in these spaces can be ensured by rotating the tubular member, but depending on the size of these spaces, it may be necessary to increase the rotation angle of the tubular member to ensure airtightness. This reduces the worker's work efficiency.

[0019] Therefore, it is preferable that a plurality of insertion regions are pre-set in the internal space of the surrounding portion as regions through which the plurality of linear members are respectively inserted, and that the fiber amount of the partition regions is adjusted so that, when the tubular member is rotated by a pre-set angle, the partition regions formed between the insertion regions have a fiber amount sufficient to fill the inter-region regions, and the partition regions formed between the insertion regions and the surrounding portion have a fiber amount sufficient to fill the outer regions.

[0020] According to this aspect, the amount of fiber in the partitioning portion is adjusted so as to efficiently ensure airtightness in the inter-regional regions formed between the insertion regions and the outer region formed between the insertion region and the surrounding portion, thereby preventing a decrease in the worker's work efficiency.

[0021] As described above, the partition portion is formed of a plurality of intertwined fibers that are arranged to block the internal space of the surrounding portion, making it difficult to determine which region of the internal space of the surrounding portion is the insertion region.

[0022] Therefore, it is preferable that the attachment member has a coloring treatment applied to the insertion area of ​​the partition portion.

[0023] According to this aspect, the locations of the multiple insertion regions in the internal space of the enclosing portion become clear.

[0024] As described above, the surrounding portion is attached to the tubular member. However, if the surrounding portion is attached to the outer surface of the tubular member, the surrounding portion gets in the way when the worker rotates the tubular member, which reduces the worker's workability.

[0025] Therefore, in the mounting member, it is preferable that the surrounding portion is attached to the inner surface of the tubular member and is housed in the tubular member so as to fit within the area in which the tubular member extends in the axial direction along the axis.

[0026] According to this aspect, since the surrounding portion is housed inside the tubular member, a decrease in the worker's workability when rotating the tubular member is suppressed.

[0027] As described above, the mounting member causes the partitioning portion to entangle the linear member in response to the rotation of the tubular member, thereby winding the surrounding portion around the linear member. Here, a restoring force that rotates the rotated tubular member in the opposite direction to the rotation direction may be generated in the partitioning portion or surrounding portion. In this case, the tubular member rotates in the opposite direction to the rotation direction, creating gaps in the chambers through which the linear members of the partitioning portion pass, making it difficult to ensure airtightness between the planar member and the multiple linear members.

[0028] Therefore, it is preferable that the mounting member has a rotation control means that controls the relative rotation of the tubular member with respect to the support member facing in the opposite direction to the direction in which the tubular member is rotated when the tubular member is rotated by a predetermined angle.

[0029] According to this aspect, the tubular member that has been rotated by a predetermined angle is prevented from rotating in the opposite direction, thereby maintaining airtightness between the planar member and the linear member.

[0030] However, depending on the tension applied to the linear members, the tubular member may move in the axial direction relative to the support member. When the tubular member moves in the axial direction, the entanglement of the partition portion around the linear members and the wrapping of the enclosing portion around the linear members may loosen.

[0031] Therefore, it is preferable that the mounting member further includes a movement restricting means for restricting relative movement of the tubular member with respect to the support member in the axial direction.

[0032] According to this aspect, it is possible to prevent the entanglement of the partitioning portion and the wrapping of the surrounding portion from loosening as the tubular member moves in the axial direction. [Effects of the Invention]

[0033] According to the present invention, the efficiency of the work of attaching a plurality of linear members to a planar member while ensuring airtightness between the planar member and the linear members is improved. [Brief explanation of the drawings]

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a cross-sectional view schematically showing an attachment member 10 according to one embodiment of the present invention. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. Fig. 3 is a cross-sectional view showing the attachment member 10 in which the tubular member 30 has been rotated to a preset angle. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3. Fig. 5 is an enlarged view of region V in Fig. 1. Fig. 6 is an enlarged view of region VI in Fig. 3. Fig. 7 is a cross-sectional view taken along line VII-VII in Fig. 5, showing the area where the needle-shaped member (rotation restricting means) 80 is disposed by encircling it.

[0036] The mounting member 10 according to this embodiment is used to airtightly mount a plurality of linear members 11, such as wiring or piping, to a planar member 13 that extends along a predetermined plane such as a floor or a wall. Here, an example will be described in which three circular linear members 11 are mounted to the planar member 13 by the mounting member 10. However, the number and shape of the linear members 11 can be changed as appropriate. As shown in FIG. 1 , the mounting member 10 includes a support member 20 that is mounted to the planar member 13, a tubular member 30 that is rotatably supported by the support member 20, and a sealing means 150 that is attached to the tubular member 30.

[0037] The planar member 13 has a first surface 13A facing a predetermined plane such as a floor or an exterior wall, and a second surface 13B facing in the opposite direction from the first surface 13A. The planar member 13 is, for example, an interior wall substrate or ceiling substrate of a building constructed of gypsum board or the like. As shown in FIG. 1 , the planar member 13 according to this embodiment is provided with one first through hole 12 (corresponding to the "through hole" described in the claims) for passing multiple linear members 11 through. However, the planar member 13 may be provided with multiple first through holes 12 for passing each of the linear members 11 through.

[0038] The support member 20 is a member for supporting the tubular member 30. Specifically, the support member 20 has an attachment portion 21 that is airtightly attached to the area around the first through hole 12 in the planar member 13, and a peripheral wall 22 that extends in a first direction (see FIG. 1 ) on the second surface 13B side of the planar member 13 and surrounds the periphery of the multiple linear members 11 that have passed through the first through hole 12 with an axis AX extending along the first direction as its center.

[0039] The mounting portion 21 is, for example, a rectangular plate extending along the second surface 13B of the planar member 13. As shown in FIG. 1 , the mounting portion 21 has one second through hole 14 for passing multiple linear members 11 at a position overlapping the first through hole 12. The mounting portion 21 also has an adhesive surface 21A facing the second surface 13B of the planar member 13 and having a predetermined adhesive applied over substantially the entire surface. Here, the positions of the first through hole 12 and the second through hole 14 are adjusted so that the multiple linear members 11 can pass through the first through hole 12 and the second through hole 14, and then the adhesive surface 21A of the mounting portion 21 is abutted against the area surrounding the first through hole 12 on the second surface 13B of the planar member 13. This allows the mounting portion 21 to be airtightly adhered to the second surface 13B. However, the method for airtightly attaching the mounting portion 21 to the second surface 13B is not limited to the above example and can be modified as appropriate.

[0040] As shown in Fig. 5, peripheral wall 22 has a main body portion 23 extending in a first direction from mounting portion 21, and a protrusion 24 provided from main body portion 23 around the entire circumference of peripheral wall 22. Protrusion 24 has a tip surface 25 facing radially outward from peripheral wall 22, a first convex side surface 26A extending perpendicular to tip surface 25 and facing the first direction, and a second convex side surface 26B extending perpendicular to tip surface 25 and facing the direction opposite to the first direction. Also, as shown in Fig. 5, peripheral wall 22 has a locked portion 27 provided from main body portion 23 around the entire circumference of peripheral wall 22 in a region opposite to protrusion 24 in the first direction. The engaging portion 27 has a peripheral wall side inclined surface 28 that inclines so as to extend radially outward from the peripheral wall 22 as it moves away from the protrusion 24, and a peripheral wall side saw-tooth surface 29 that extends radially inward from the peripheral wall side inclined surface 28 and faces in the direction opposite to the first direction.

[0041] The tubular member 30 is a member that is supported rotatably about the axis AX relative to the peripheral wall 22 while surrounding the periphery of the plurality of linear members 11. The tubular member 30 is supported by the peripheral wall 22 while the peripheral wall 22 is fitted inside the tubular member 30. Specifically, the tubular member 30 is formed with a recess 31 into which the protrusion 24 is inserted from the inside, and a locking recess 34 that can lock the locked portion 27 from the inside. The recess 31 and the locking recess 34 are each formed over the entire circumference centered on the axis AX.

[0042] Insertion of the protrusion 24 into the recess 31 restricts axial movement of the tubular member 30 relative to the peripheral wall 22. Specifically, abutment between the second convex side surface 26B of the protrusion 24 and the second recessed side surface 33, which extends perpendicularly from the bottom surface of the recess 31 and faces the first direction, restricts movement of the tubular member 30 in the axial direction away from the mounting portion 21. Meanwhile, the first convex side surface 26A of the protrusion 24 and the first recessed side surface 33A, which extends perpendicularly from the bottom surface of the recess 31 and faces the direction opposite to the first direction, abut against each other via the seal member 38, and this abutment restricts movement of the tubular member 30 in the axial direction toward the mounting portion 21. Furthermore, during this abutment, the seal member 38 is compressed between the first convex side surface 26A and the first recessed side surface 33A, thereby connecting the peripheral wall 22 and the tubular member 30 in an airtight state. In this embodiment, the sealing member 38 is provided on the first concave side surface 33A of the recess 31, but may be provided on the first convex side surface 26A of the protrusion 24.

[0043] Furthermore, when the first concave side surface 33A of the recess 31 abuts against the first convex side surface 26A of the protrusion 24, the peripheral wall 22 and the tubular member 30 are locked to each other in the circumferential direction about the axis AX. Specifically, a needle-like member 80 extending toward the first convex side surface 26A of the protrusion 24 is provided on the first concave side surface 33A of the recess 31. The needle-like member 80 is inserted into the first convex side surface 26A of the protrusion 24, thereby locking the peripheral wall 22 and the tubular member 30 to each other in the circumferential direction. Note that the needle-like member 80 may be provided on the protrusion 24.

[0044] The needle-like member 80 is inserted into the first convex side surface 26A of the protrusion 24 while passing through the sealing member 38. In this state, the sealing member 38 is compressed and deformed between the first concave side surface 33A and the first convex side surface 26A, and the gap between the needle-like member 80 and the inner circumferential surface of the hole formed in the sealing member 38 is filled by the sealing member 38. This creates an airtight state between the sealing member 38 and the inner circumferential surface of the hole.

[0045] Supplementally, the tubular member 30 according to this embodiment has a plurality of needle-like members 80. Specifically, as shown in Fig. 7, the plurality of needle-like members 80 are arranged at predetermined intervals on the circumference of the tubular member 30. For ease of explanation, the surrounding portion 40 and the partition portion 50 are not shown in Fig. 7.

[0046] The locking recess 34 also has a tube-side serrated surface 36 that can be locked with the peripheral wall-side serrated surface 29, and a tube-side inclined surface 35 that extends from the tube-side serrated surface 36 and inclined so as to extend radially inward of the tubular member 30 as it approaches the recess 31 in the axial direction. In this embodiment, the locking recess 34 and the locked portion 27 function as a movement restricting means that restricts relative axial movement of the tubular member 30 with respect to the support member 20. Here, the locking recess 34 climbs over the peripheral wall-side inclined surface 28, and the peripheral wall-side serrated surface 29 and the tube-side serrated surface 36 are locked together, thereby restricting movement of the tubular member 30 in the direction opposite to the first direction in the axial direction.

[0047] In this embodiment, the engagement position between the peripheral wall side sawtooth surface 29 and the tube side sawtooth surface 36 coincides with the engagement position between the first concave side surface 33A of the recess 31 and the first convex side surface 26A of the protrusion 24.

[0048] Additionally, the locking recess 34 and the locked portion 27 according to this embodiment also function as a rotation restricting means for restricting relative rotation of the tubular member 30 with respect to the support member 20 in the direction opposite to the direction in which the tubular member 30 was rotated by a preset angle (hereinafter simply referred to as reverse rotation). Specifically, when the peripheral wall side serrated surface 29 and the tube side serrated surface 36 are engaged with each other, a frictional force is generated between the tube side serrated surface 36 and the peripheral wall side serrated surface 29. The reverse rotation of the tubular member 30 is restricted by this frictional force.

[0049] The sealing means 150 seals the internal space IS of the tubular member 30 so as to ensure airtightness between the plurality of linear members 11 and the planar member 13. As shown in Fig. 1, the sealing means 150 has an enclosing section 40 that is airtightly attached to the tubular member 30 and surrounds the plurality of linear members 11 from the outside, and a partitioning section 50 that partitions the internal space IS of the enclosing section 40 into a plurality of rooms.

[0050] The surrounding portion 40 surrounds the axis AX so as to form an internal space IS (see FIGS. 2 and 4) that surrounds the multiple linear members 11. Here, for example, a film-like member that is more flexible and airtight than the tubular member 30 is used as the surrounding portion 40. As shown in FIG. 1 , the surrounding portion 40 is attached to the inner surface 37 of the tubular member 30. The surrounding portion 40 is housed in the tubular member 30 so as to fit within the region in which the tubular member 30 extends in the axial direction. The surrounding portion 40 according to this embodiment has an outer end portion 41 connected to the inner surface 37 of the tubular member 30, an inner end portion 43 that is the end opposite to the outer end portion 41 and is connected to the partition portion 50, and an intermediate portion 42 located between the outer end portion 41 and the inner end portion 43.

[0051] The outer end 41 is airtightly attached to the inner surface 37 of the tubular member 30 using an adhesive or the like.

[0052] The inner end 43 is connected to the partitioning portion 50. As shown in Fig. 8, in this embodiment, a holding mechanism 45 that entangles and holds the fibers is provided around the entire periphery of the inner surface 37 formed by the inner end 43 of the enclosing portion 40. Here, the holding mechanism 45 is formed, for example, by a wire having a plurality of loop portions 45A so that the fibers can be entangled and held.

[0053] The intermediate portion 42 is a portion that is wound around the plurality of linear members 11 in response to the rotation of the tubular member 30. More specifically, the intermediate portion 42 is a portion that is wound around the plurality of linear members 11 via the partition portion 50 that is entangled with the plurality of linear members 11.

[0054] The partitioning portion 50 divides the internal space IS of the surrounding portion 40 into multiple chambers through which the linear members 11 are inserted. That is, the partitioning portion 50 has walls 51 that divide the multiple chambers. The partitioning portion 50 according to this embodiment has higher flexibility than the tubular member 30 and has a characteristic of undergoing compressive deformation so that the walls 51 become thinner when the surrounding portion 40 receives an external force that reduces the internal space IS of the surrounding portion 40. Here, the partitioning portion 50 is formed, for example, from multiple intertwined fibers (see FIG. 10 ). In this case, the partitioning portion 50 is provided so as to close the internal space IS of the surrounding portion 40, but due to the nature of fibers, numerous gaps are formed in the internal space IS of the surrounding portion 40. In this embodiment, multiple insertion regions 100 are predefined in the internal space IS of the surrounding portion 40 as regions through which the multiple linear members 11 are inserted, and the insertion regions 100 are colored. A method for defining the insertion regions 100 will be described later. Here, each linear member 11 is inserted into each insertion region 100 while pushing aside the multiple fibers that are entangled with each other, and multiple chambers shaped to follow the outer periphery of the linear member 11 are formed in the internal space IS of the surrounding part 40. In this case, the fibers arranged in the region other than the insertion region 100 in the internal space IS of the surrounding part 40 function as wall portions 51. Here, countless gaps exist between the outer periphery of each linear member 11 inserted into the insertion region 100 and the wall portions 51 that surround the outer periphery.

[0055] The process by which airtightness is ensured by the sealing means 150 will now be described. The outer end 41 of the surrounding portion 40 is attached to the inner surface 37 of the tubular member 30. Therefore, when the tubular member 30 is rotated, the outer end 41 rotates, and the intermediate portion 42 also gradually begins to rotate, starting from the portion closest to the tubular member 30. Meanwhile, the multiple linear members 11, which are not directly affected by the rotational force of the tubular member 30, tend to remain in place in the internal space IS of the surrounding portion 40. Thus, a difference in the amount of rotation occurs between the portion of the intermediate portion 42 closest to the tubular member 30 and the portion closest to the partitioning portion 50, causing the intermediate portion 42 to twist. As a result, the intermediate portion 42 is wrapped around the multiple linear members 11, and the partitioning portion 50 becomes entangled with the multiple linear members 11. As a result of the partitioning portion 50 becoming entangled with the multiple linear members 11, an external force is generated in the surrounding portion 40 in a direction that reduces the internal space IS of the surrounding portion 40. From the viewpoint of efficiently entangling the partition portion 50 around the linear members 11, it is preferable for the worker to fix the multiple linear members 11 when rotating the tubular member 30. As a fixation method, for example, the worker may grip the multiple linear members 11. Alternatively, as shown in FIG. 9 , the multiple linear members 11 may be fixed using an auxiliary tool. Specifically, the auxiliary tool includes a restraint 60 for preventing the rotational force of the tubular member 30 from being transmitted to the multiple linear members 11, and a restraint support member 61 for supporting the restraint 60. The restraint 60 includes a cable tie for binding the multiple linear members 11. For ease of explanation, FIG. 9 shows the multiple linear members 11 in a state before the cable tie is fastened to the multiple linear members 11. When using the restraint 60, the multiple linear members 11 are fixed by fastening the cable tie. The restraint support member 61 includes multiple wires or multiple fibers having an end fixed to the restraint 60 and an end fixed to the mounting portion 21. In order to prevent the rotational force of the tubular member 30 from being transmitted to the wire or fiber via the restraining device 60, the wire or fiber is connected to the restraining device 60 and the attachment portion 21 in a state where it is tensioned to a certain extent.

[0056] As described above, in this embodiment, by rotating the tubular member 30, the partitioning portion 50 becomes entangled with the plurality of linear members 11, and the intermediate portion 42 of the surrounding portion 40 becomes wound around the plurality of linear members 11 via the partitioning portion 50. This brings the outer periphery of each linear member 11 inserted into the insertion region 100 into tight contact with the wall portion 51 surrounding the outer periphery. As a result, the countless gaps that existed between the outer periphery of each linear member 11 inserted into the insertion region 100 and the wall portion 51 surrounding the outer periphery are closed, ensuring airtightness between the plurality of linear members 11 and the wall portion 51. Furthermore, by the partitioning portion 50 becoming entangled with the plurality of linear members 11 and the intermediate portion 42 of the surrounding portion 40 becoming wound around the plurality of linear members 11 via the partitioning portion 50, the partitioning portion 50 undergoes compressive deformation such that the wall portion 51 becomes thinner. As a result, the numerous gaps that existed between the plurality of fibers that make up the wall portion 51 are filled, and the airtightness of the wall portion 51 is ensured.

[0057] Next, the operation of the rotation restricting means will be described. As described above, in the mounting member 10 according to this embodiment, the surrounding portion 40 is wound around the plurality of linear members 11 by twisting the surrounding portion 40 in response to the rotation of the tubular member 30, and therefore a reaction force is generated in the surrounding portion 40 in a direction that causes the twist to unfold. If the twist in the surrounding portion 40 unfolds due to this reaction force, it becomes difficult to ensure airtightness between the planar member 13 and the linear members 11.

[0058] Here, the mounting member 10 according to this embodiment has a needle-like member 80 and a protrusion 24 that function as rotation restricting means. Here, after completing the rotation operation of the tubular member 30, the worker moves the tubular member 30 in the axial direction opposite to the first direction so that, for example, the sealing member 38 is sandwiched between the first concave side surface 33A and the first convex side surface 26A. As a result, the needle-like member 80 pierces the first convex side surface 26A of the protrusion 24 in the axial direction, and reverse rotation of the tubular member 30 is restricted.

[0059] Next, the operation of the movement restricting means will be described. In this embodiment, tension applied to the multiple linear members 11 may cause the tubular member 30 to move relative to the support member 20 in the axial direction. For example, after the tubular member 30 has been rotated, the multiple linear members 11 may be connected to a predetermined instrument that is disposed in a first axial direction relative to the tubular member 30. Depending on the lengths of the multiple linear members 11, the multiple linear members 11 may be pulled in the first axial direction during this operation. As described above, after the tubular member 30 has been rotated, the tubular member 30 is connected to the multiple linear members 11 via the partition portion 50 and the surrounding portion 40. Therefore, when the multiple linear members 11 are pulled in the first axial direction, the tubular member 30 is pulled in the first axial direction. In this manner, relative movement of the tubular member 30 in the axial direction occurs. When the tubular member 30 moves in the first axial direction, the degree to which the partition portion 50 is entangled with the plurality of linear members 11 and the degree to which the enclosing portion 40 is wound around the plurality of linear members 11 may loosen.

[0060] Here, the mounting member 10 according to this embodiment has a locked portion 27 and a locking recess 34 that function as movement restricting means. Here, after completing the rotation operation of the tubular member 30, the worker moves the tubular member 30 in the axial direction opposite to the first direction, for example, so that the locking recess 34 moves over the locked portion 27 and the peripheral wall side sawtooth surface 29 faces the tube side sawtooth surface 36. This restricts the axial movement of the tubular member 30 relative to the support member 20, and also prevents the entanglement of the partition portion 50 and the winding of the enclosing portion 40 from loosening.

[0061] Next, a method for determining the insertion region 100 will be described with reference to Fig. 10 and Fig. 11. Fig. 10 is a cross-sectional view schematically showing the mounting member 10 of Fig. 1, with an enlarged view of region IX. Fig. 11 is a cross-sectional view schematically showing the mounting member 10 of Fig. 3, with an enlarged view of region X. For ease of explanation, the cross-sectional portions of the linear member 11 are not hatched in Fig. 10 and Fig. 11.

[0062] As described above, in this embodiment, a plurality of insertion regions 100 are set in advance. When a plurality of insertion regions 100 are set, an inter-region region 110 (see FIG. 10 ) formed between the insertion regions 100 and an outer region 120 (see FIG. 10 ) formed between the insertion region 100 and the surrounding portion 40 are formed in the internal space IS of the surrounding portion 40. These spaces are covered by the partition portion 50, and airtightness must be ensured. Depending on the size of these spaces, it may be necessary to increase the rotation angle of the tubular member 30 to ensure airtightness, which reduces the worker's work efficiency.

[0063] From the viewpoint of efficiently ensuring airtightness in the inter-region regions 110, it is preferable that partitions 50 having a fiber amount sufficient to fill the inter-region regions 110 when the tubular member 30 is rotated by a preset angle be arranged in the inter-region regions 110. Specifically, it is preferable that the fiber amount of the partitions 50 be adjusted so that the total value of the surface area of ​​the fibers arranged in the inter-region regions 110 when the mounting member 10 is viewed in the axial direction in the initial state (see FIG. 10 ) before the tubular member 30 is rotated is greater than the surface area of ​​the inter-region regions 110 when the mounting member 10 is viewed in the axial direction when the tubular member 30 is rotated by a preset angle (see FIG. 11 ) (hereinafter referred to as the "inter-region surface area").

[0064] For ease of explanation, in the initial state before the tubular member 30 is rotated, when the mounting member 10 is viewed in the axial direction, the fibers in the regions between the insertion regions 100 are considered to be arranged in a lattice pattern (see the enlarged view of region IX in Figure 10).

[0065] Under this assumption, the inter-region fiber surface area can be calculated by multiplying the length and thickness of each fiber placed in the region between the insertion regions 100 by the total number of fibers placed in the region between the insertion regions 100.

[0066] Here, the inter-region surface area can be calculated by subtracting the areas of three sectors FS with an interior angle of 60 degrees from the area of ​​an equilateral triangle ET formed by connecting the center points O of the three linear members 11 with straight lines. Specifically, if the diameter of the linear member 11 is L, the inter-region surface area can be calculated by the following formula (1).

[0067] √3×L 2 ÷4-π×L 2 ÷8 ≒ 0.04L 2 ···(1) Therefore, in this embodiment, the inter-region fiber surface area is 0.04L 2 The fiber amount in the partition 50 is adjusted so that the inter-region fiber surface area is greater than 0.04L. 2 The plurality of insertion regions 100 are set so that the partitions 50 having a fiber amount that can be larger than the amount of fiber in the region 110 in the initial state before the tubular member 30 is rotated are disposed in the region 110 between the regions. This ensures efficient airtightness in the region 110 between the regions.

[0068] Similarly, from the viewpoint of efficiently ensuring airtightness in the outer region 120, it is preferable that the partitions 50 have a fiber amount sufficient to fill the outer region 120 when the tubular member 30 is rotated by a preset angle. Specifically, it is preferable that the fiber amount of the partitions 50 is adjusted so that the total value of the surface area of ​​the fibers arranged in the outer region 120 when the mounting member 10 is viewed in the axial direction in the initial state (see FIG. 10 ) before the tubular member 30 is rotated is greater than the surface area of ​​the outer region 120 when the mounting member 10 is viewed in the axial direction when the tubular member 30 is rotated by a preset angle (see FIG. 11 ) (hereinafter referred to as the “outer surface area”).

[0069] The method for calculating the outer fiber surface area is substantially the same as the method for calculating the inter-region fiber surface area, and therefore, a description thereof will be omitted here.

[0070] Here, the outer surface area can be calculated by subtracting the area of ​​two sectors FS with an interior angle of 90 degrees from the area of ​​a rectangle RC whose short sides are lines drawn perpendicularly from the center point O of the linear member 11 to the point of contact P between the linear member 11 and the surrounding portion 40 and whose long sides are lines connecting the short sides. Specifically, if the diameter of the linear member 11 is L, the outer surface area can be calculated by the following formula (2).

[0071] L 2 ÷2-π×L 2 ÷8 ≒ 0.11L 2 ···(2) Therefore, in this embodiment, the outer fiber surface area is 0.11 L 2 The amount of fiber in the compartment 50 is adjusted so that the outer fiber surface area is greater than 0.11L. 2 The plurality of insertion regions 100 are set so that the partitions 50 having a fiber amount that can be larger than the amount of fiber in the outer region 120 in the initial state before the tubular member 30 is rotated. This ensures airtightness in the outer region 120 efficiently.

[0072] Note that the above formulas (1) and (2) are calculated on the assumption that each of the linear members 11 is a perfect circle and that the diameters of the linear members 11 are all the same length. Also, in the above formulas (1) and (2), it is assumed that the fibers between the linear members 11 and the fibers between the linear members 11 and the surrounding portion 40 are sufficiently compressed, and the areas of these fibers are ignored in the calculations.

[0073] Next, the features and effects of the mounting member 10 will be listed.

[0074] In this embodiment, the mounting member 10 is provided with one or more through holes for passing a plurality of linear members 11, and is used to airtightly mount the linear members 11 inserted into the through holes to a planar member 13 extending along a predetermined plane, the mounting member 10 including a mounting portion 21 airtightly mounted in an area surrounding the through hole in the planar member 13, and a peripheral wall 22 extending from the mounting portion 21 in a first direction opposite the planar member 13 and surrounding the linear members 11 that have passed through the through holes with an axis AX extending along the first direction as its center, and a support member 20 surrounding the linear members 11 and airtightly mounted to the peripheral wall 22. and a sealing means 150 configured to have a tubular member 30 capable of forming a linear member 11 and supported by a peripheral wall 22 so as to be rotatable about an axis AX, a surrounding section 40 airtightly attached to the tubular member 30 and surrounding the linear member 11 from the outside, and a partition section 50 that partitions the internal space IS within the surrounding section 40 into a plurality of chambers for inserting each of the linear members 11 therethrough, and to have the partition section 50 entangled with the linear member 11 and reduce the internal space IS of the surrounding section 40 in response to a rotational operation of the tubular member 30, and to have the surrounding section 40 wrapped around the linear member 11.

[0075] In this embodiment, the mounting member 10 has the sealing means 150, so that the partitioning portion 50 entangles with the linear member 11 in response to the rotation of the tubular member 30, reducing the internal space IS of the surrounding portion 40 and winding the surrounding portion 40 around the linear member 11. According to this aspect, by rotating the tubular member 30 by a predetermined angle or more, the sealing means 150 can close the gaps in each chamber of the partitioning portion 50 through which the linear member 11 passes.

[0076] Furthermore, in this embodiment, the mounting member 10 is attached to the planar member 13 in an airtight state, the peripheral wall 22 supports the tubular member 30 in an airtight state, and the surrounding portion 40 is attached to the tubular member 30 in an airtight state. Thus, in this embodiment, the mounting member 10 is configured so that the airtightness of each of the linear members 11 constituting the multiple linear members 11 relative to the planar member 13 is ensured collectively by performing a simple operation such as rotating the tubular member 30. Therefore, the mounting member 10 according to this embodiment improves the efficiency of the work of attaching the multiple linear members 11 to the planar member 13 while ensuring airtightness between them.

[0077] In the mounting member 10, it is preferable that the partitioning portion 50 has the property of compressing and deforming so that the wall portions 51 that partition the multiple rooms become thinner when the surrounding portion 40 receives an external force in a direction that reduces the internal space IS of the surrounding portion 40.

[0078] According to this embodiment, as the surrounding portion 40 wraps around the linear member 11, the partition portion 50 can flexibly fill the gaps between the linear members 11 and the gaps between the linear member 11 and the surrounding portion 40.

[0079] In the attachment member 10, the partitioning portion 50 is preferably formed by a plurality of fibers intertwined with each other, and is provided so as to close the internal space IS of the surrounding portion 40.

[0080] According to this embodiment, by rotating the tubular member 30, the plurality of fibers can be entangled with the plurality of linear members 11, with the plurality of fibers filling gaps between the linear members 11 and gaps between the linear members 11 and the surrounding portion 40. Furthermore, when the tubular member 30 is rotated, the plurality of fibers are compressed between the linear members 11 and between the surrounding portion 40 and the linear members 11, thereby increasing the density of the plurality of fibers per unit area. Therefore, by rotating the tubular member 30 by a predetermined angle or more, it is possible to ensure airtightness between the planar member 13 and the plurality of linear members 11.

[0081] In the mounting member 10, it is preferable that a holding mechanism 45 that holds the fibers by entangling them is provided around the entire periphery of the inner surface 44 of the surrounding portion 40.

[0082] According to this embodiment, the partitioning section 50 formed of a plurality of fibers can be entangled and held by the holding mechanism 45. This makes it easier to attach the partitioning section 50 to the surrounding section 40 compared to attaching the partitioning section 50 to the surrounding section 40 using an adhesive or the like.

[0083] Furthermore, when the partitioning section 50 is attached to the surrounding section 40 using an adhesive or the like, the portion of the partitioning section 50 to which the adhesive or the like is applied may separate from the other portions, causing the partitioning section 50 to come off from the surrounding section 40. In contrast, when the holding mechanism 45 holds the partitioning section 50 by entangling the fibers, the attachment state between the surrounding section 40 and the partitioning section 50 can be stabilized.

[0084] Incidentally, the internal space IS of the surrounding part 40 includes spaces between the linear members 11 and spaces surrounded by the linear members 11 and the surrounding part 40. Airtightness in these spaces is ensured by rotating the tubular member 30, but depending on the size of these spaces, it may be necessary to increase the rotation angle of the tubular member 30 to ensure airtightness. In this case, the worker's work efficiency decreases.

[0085] Therefore, it is preferable that a plurality of insertion regions 100 are pre-set in the internal space IS of the surrounding portion 40 as regions through which a plurality of linear members 11 are respectively inserted, and that when the tubular member 30 is rotated by a pre-set angle, a partition section 50 having a fiber amount sufficient to fill the inter-region region 110 formed between the insertion regions 100 is arranged in the inter-region region 110, and that the fiber amount of the partition section 50 is adjusted so that a partition section 50 having a fiber amount sufficient to fill the outer region 120 formed between the insertion region 100 and the surrounding portion 40 is arranged in the outer region 120.

[0086] According to this embodiment, the amount of fiber in the partitioning portion 50 is adjusted so as to efficiently ensure airtightness in the inter-region region 110 formed between the insertion regions 100 and the outer region 120 formed between the insertion region 100 and the surrounding portion 40. This prevents a decrease in the worker's work efficiency.

[0087] As described above, the partition portion 50, which is a plurality of intertwined fibers, is provided so as to block the internal space IS of the surrounding portion 40. In this case, it is difficult to determine which region of the internal space IS of the surrounding portion 40 is the insertion region 100.

[0088] Therefore, in the mounting member 10, it is preferable that the insertion region 100 of the partition section 50 is colored.

[0089] According to this embodiment, the locations of the multiple insertion regions 100 in the internal space IS of the surrounding portion 40 become clear.

[0090] As described above, the surrounding portion 40 is attached to the tubular member 30. However, if the surrounding portion 40 is attached to the outer surface of the tubular member 30, the surrounding portion 40 gets in the way when an operator rotates the tubular member 30. This reduces the operator's work efficiency.

[0091] Therefore, in the mounting member 10, it is preferable that the surrounding portion 40 is attached to the inner surface 37 of the tubular member 30 and is housed in the tubular member 30 so as to fit within the area in which the tubular member 30 extends in the axial direction along the axis AX.

[0092] According to this aspect, since the surrounding portion 40 is housed inside the tubular member 30, the workability of the worker when rotating the tubular member 30 is prevented from being reduced.

[0093] As described above, the mounting member 10 causes the partitioning portion 50 to entangle the linear member 11 in response to the rotation of the tubular member 30, thereby winding the surrounding portion 40 around the linear member 11. Here, a restoring force that rotates the rotated tubular member 30 in the opposite direction to the direction of rotation may be generated in the partitioning portion 50 or the surrounding portion 40. In this case, the tubular member 30 rotates in the opposite direction to the direction of rotation, creating gaps in the chambers through which the linear members 11 of the partitioning portion 50 pass, making it difficult to ensure airtightness between the planar member 13 and the multiple linear members 11.

[0094] Therefore, it is preferable that the mounting member 10 has a rotation restriction means that restricts the relative rotation of the tubular member 30 with respect to the support member 20 facing in the opposite direction to the direction in which the tubular member 30 is rotated when the tubular member 30 is rotated by a predetermined angle.

[0095] According to this embodiment, the tubular member 30, which has been rotated by a preset angle, is prevented from rotating in the opposite direction, thereby maintaining airtightness between the planar member 13 and the linear member 11.

[0096] Incidentally, depending on the tension applied to the linear members 11, there is a possibility that the tubular member 30 will move in the axial direction relative to the support member 20. When the tubular member 30 moves in the axial direction, there is a possibility that the degree to which the partition portion 50 is entangled with the plurality of linear members 11 and the degree to which the enclosing portion 40 is wound around the plurality of linear members 11 will loosen.

[0097] Therefore, the mounting member 10 further includes a movement restricting means for restricting the relative movement of the tubular member 30 with respect to the support member 20 in the axial direction.

[0098] According to this embodiment, it is possible to prevent the entanglement of the partitioning portion 50 and the wrapping of the surrounding portion 40 from loosening as the tubular member 30 moves in the axial direction.

[0099] (Other embodiments) Other embodiments of the present invention will now be described.

[0100] In the above embodiment, an example has been described in which the protrusion 24 and the needle-shaped member 80 function as the rotation restricting means. However, the example of the rotation restricting means is not limited to this, and the rotation restricting means may be any means that engages with each other in the circumferential direction around the axis AX.

[0101] Furthermore, in the above embodiment, an example was described in which the tubular member 30 has multiple needle-shaped members 80 arranged at predetermined intervals around the circumference of the tubular member 30, but the tubular member 30 may have only one needle-shaped member 80.

[0102] In the above embodiment, the locking recess 34 and the locked portion 27 as the movement restricting means also function as the rotation restricting means. However, the locking recess 34 and the locked portion 27 are not limited to this.

[0103] For example, the locking recess 34 and the locked portion 27 may have only the function as movement restricting means. Specifically, instead of the tube-side sawtooth surface 36, the locking recess 34 may have a linear tube-side straight surface (not shown) that extends radially outward from the tube-side inclined surface 35 of the tubular member 30 and faces the first direction, and instead of the peripheral wall-side inclined surface 28, the locked portion 27 may have a linear peripheral wall-side straight surface (not shown) that extends radially inward from the peripheral wall-side inclined surface 28 of the peripheral wall 22 and faces the direction opposite to the first direction. In other words, each of the locking recess 34 and the locked portion 27 does not necessarily have to have a surface that is formed in a sawtooth shape.

[0104] Furthermore, in the above embodiment, an example has been described in which the mounting member 10 has the needle-shaped member 80 and the protrusion 24 as the rotation restricting means, and the locking recess 34 and the locked portion 27 as the movement restricting means. However, examples of the movement restricting means and the rotation restricting means are not limited to these. For example, the mounting member 10 may be configured so that a predetermined fastening member (not shown), such as a screw, functions as the rotation restricting means and the movement restricting means. In this case, by fastening the tubular member 30 and the peripheral wall 22 together using the fastening member after rotating the tubular member 30 to a predetermined angle, reverse rotation of the tubular member 30 and movement of the tubular member 30 relative to the support member 20 in the axial direction are restricted.

[0105] In the above embodiment, an example has been described in which the planar member 13 is formed by an inner wall substrate or a ceiling substrate. However, the example of the planar member 13 is not limited to this. For example, the planar member 13 may be formed by the wall portion of a socket box embedded inside the inner wall. Specifically, the planar member 13 may be formed by the wall portion of a socket box attached to the inner side of the inner wall of the inner wall substrate, which has through holes for passing multiple linear members 11, so as to surround the through holes. In this case, the support member 20 is attached to the wall portion of the socket box so as to extend from the wall portion of the socket box toward the inner side of the inner wall. Furthermore, the tubular member 30 is attached to the support member 20 so as to extend from the support member 20 toward the inner side of the inner wall. [Explanation of symbols]
