For example, the inspection lid of Patent Document 1 includes a surface material formed in a dish shape using a PVC steel plate and the like, and a backing material such as a gypsum board adhered to the back surface thereof. It consists of the opening part formed in a part of ceiling panel formed using the steel plate etc., and the edge of the PVC steel plate which faces the opening part is bent at right angle, and it is set as the edge member.
As described above, the bathroom ceiling is often formed by using a panel material such as a PVC steel plate, but the appearance of the end face of the inspection port is poor, and the appearance of the bathroom ceiling may be impaired. Moreover, since it is difficult to adjust the dimensions of the panel material as described above, there may be a large gap between the end surface of the inspection port and the end surface of the inspection lid. If such a gap is generated, the appearance of the bathroom ceiling is impaired, and steam in the bathroom may enter the back of the ceiling.

In addition, in bathroom ceilings and inspection lids with interior sheets affixed to the surfaces of ceiling and lid base materials, the edges of the interior sheets can be seen from the end face of the inspection port or the end face of the inspection lid, so the appearance will be poor. There is. Furthermore, moisture may enter from between the edge of the interior sheet and the surface of the inspection lid, and the interior sheet may peel off from the edge.
In particular, bathroom ceilings are prone to mold and bacteria, and look bad over time. In recent years, renovated bathrooms have been renovated in houses such as detached houses and condominiums, geriatric health facilities, nursing care facilities, and hospitals. There are many new constructions. When renovating the bathroom ceiling, the existing bathroom ceiling may be removed and replaced with new interior materials. However, for cost reasons, it is desirable to attach an interior sheet on the existing interior materials. ing. It is also desired to improve the beauty around the inspection opening on the bathroom ceiling to which such an interior sheet is attached.

[One Embodiment]
[Edge members]
The edge member of this invention is attached to the end surface of the inspection port of a bathroom. Moreover, the edge member of this invention is attached to the end surface of the inspection lid | cover of a bathroom. The edge member of the present invention may be used by being attached to both the end surface of the inspection port and the end surface of the inspection lid in the bathroom, or may be used by being attached to either the end surface of the inspection port or the end surface of the inspection lid. You can also.

In FIG.1 and FIG.2, the edge member 1 for bathroom inspection openings or bathroom inspection lids is the elongate shape extended in one direction as a whole. The long shape refers to a shape in which the length in the longitudinal direction is sufficiently longer than the length in the direction perpendicular thereto. The long edge member 1 has, for example, a length in the longitudinal direction of 50 cm or more, and preferably 100 cm or more. The long edge member 1 is cut into an appropriate length for construction.
The edge member 1 includes a sticking wall 2 attached to an end face of a bathroom inspection port or an end face of a bathroom check lid, and a protruding portion from the sticking wall 2 and a surface portion around the inspection mouth or around the inspection lid. And a locking projection 3 that is locked to the surface portion. The edge member 1 has flexibility as a whole.
In addition, since the edge member 1 is elongate shape extended in a longitudinal direction, the said sticking wall 2 and the latching convex part 3 are each extended in the longitudinal direction similarly. Therefore, the edge member 1 has the same cross-sectional shape even when cut at any location in the longitudinal direction, and the cross-sectional shape is the same as the shape shown in FIG.

The edge member 1 is made of a flexible material. Here, the flexibility refers to a property that is flexible enough to be easily bent by an operator's human power. Since the flexible edge member 1 bends easily, it can follow the end face shape of the inspection port or the end face shape of the inspection lid.
For example, the hardness of the edge member 1 is 40 to 90, preferably 45 to 85, and more preferably 50 to 80. If the hardness is too small, it becomes difficult to handle the edge member 1, and if the hardness is too large, the edge member 1 may be difficult to deform according to the end face shape such as an inspection port. However, the hardness refers to a value measured by durometer type A according to JIS K 6253.

The material of the edge member 1 is not particularly limited as long as it is a flexible material. For example, the edge member 1 is formed using an elastomer such as a synthetic resin and rubber.
Examples of the elastomer include polystyrene-based thermoplastic elastomers, polyolefin-based thermoplastic elastomers, polyester-based thermoplastic elastomers, polyvinyl chloride-based thermoplastic elastomers, polyurethane-based thermoplastic elastomers, and polyamide-based thermoplastic elastomers. Since it is inexpensive and excellent in durability, a polyvinyl chloride thermoplastic elastomer is preferably used.

  The long edge member 1 can be obtained by extruding a flexible material as described above from a pressure resistant mold.

The sticking wall 2 of the edge member 1 has a strip shape elongated in the longitudinal direction. One surface of the affixing wall 2 is an affixing surface 21 in contact with the end face of the inspection port or inspection lid, and the other side of the affixing wall 2 is an exposed surface 22 exposed to the outside. The affixing surface 21 of the affixing wall 2 is flat, for example, and is adhered to the end surface of the inspection port or the inspection lid.
The locking projection 3 of the edge member 1 protrudes from the lower end of the sticking wall 2 to one side. The engaging projection 3 extends continuously from the affixing surface 21 of the affixing wall 2 and is in contact with the surface portion around the inspection port or the surface portion around the inspection lid, and the engagement surface 31. And an outer surface 32 continuous from the end to the other surface of the sticking wall 2.
The engagement surface 31 of the locking projection 3 is, for example, flat. The engaging surface 31 of the locking projection 3 and the attaching surface 21 of the attaching wall 2 are formed at substantially right angles. In this specification, “substantially right angle” includes not only strict 90 ° but also a range of 80 ° to 100 °, preferably 85 ° to 95 °.
The outer surface 32 of the locking projection 3 is formed in a cross-sectional arc shape. But the outer surface 32 of the latching convex part 3 is not restricted to a cross sectional arc shape, A cross sectional view V shape may be sufficient, or a cross sectional view concave shape may be sufficient. The shape of the outer surface 32 can absorb distortion when the edge member 1 is affixed to a corner such as an end face of the inspection port, and can prevent generation of wrinkles. A cross-sectional view arc shape is preferable because 32 is not easily soiled.

The thickness A of the affixing wall 2 of the edge member 1 is not particularly limited, but if it is too large, the edge member 1 is difficult to bend, and if it is too small, the effect of suppressing the penetration of water vapor is not sufficient, and the strength of the edge member 1 is further increased. There is a risk of shortage and handling becomes difficult. From this viewpoint, the thickness A of the sticking wall 2 is preferably 0.5 mm to 3 mm, more preferably 0.5 mm to 2 mm, and particularly preferably 0.8 mm to 1.2 mm.
The protrusion height B of the locking projection 3 of the edge member 1 is not particularly limited, but if it is too large, the edge member 1 is difficult to bend, and if it is too small, the end face of the inspection port or inspection lid may not be sufficiently concealed. In addition, there is a possibility that the locking projection 3 does not engage with a surface portion such as an inspection port during construction. From this viewpoint, the protrusion height B of the locking projection 3 is preferably 1 mm to 10 mm, more preferably 1 mm to 5 mm, and particularly preferably 1.5 mm to 3.5 mm.
The thickness C of the locking projection 3 of the edge member 1 is not particularly limited, but if it is too large, the edge member 1 is difficult to bend and the locking projection 3 protrudes greatly from the surface portion such as the inspection port after construction. The appearance may deteriorate. On the other hand, if the edge member 1 is too small, the shape of the locking projection 3 may not be maintained when the edge member 1 is attached to a corner such as the end face of the inspection port. As a result, the end surface of the inspection port or the inspection lid is sufficiently concealed. It may not be possible. From this viewpoint, the thickness C of the locking projection 3 is preferably 1 mm to 5 mm, more preferably 1.5 mm to 3 mm, and particularly preferably 1.8 mm to 2.5 mm.
The length D of the edge member 1 in the short direction of the affixing wall 2 is not particularly limited, but if it is too large, the edge member 1 becomes difficult to handle during construction, and the remaining part of the affixing wall 2 is cut off after being attached to the end face. The amount to be removed increases, and the cost increases. On the other hand, if it is too small, the end surface of the inspection port or the inspection lid may not be sufficiently concealed, and the bonding area between the end surface of the inspection port and the edge member 1 may be reduced, and the attachment strength may be insufficient. From this viewpoint, the length D in the short direction of the affixing wall 2 is preferably 5 mm to 20 mm, more preferably 7 mm to 18 mm, and particularly preferably 8 mm to 15 mm.

[Bathroom structure]
As shown in FIGS. 3 to 5, the bathroom structure 10 of the present invention includes a bathroom ceiling 4, an inspection port 5 opened in a part of the bathroom ceiling 4, an inspection lid 6 that closes the inspection port 5, Have As shown in FIG. 5, the edge member 1 is attached to at least one of the end surface 5 a of the inspection port 5 and the end surface 6 a of the inspection lid 6. In the bathroom structure 10 of the present invention, the edge member 1 may be attached to both the end surface 5a of the bathroom inspection port 5 and the end surface 6a of the inspection lid 6, or the end surface of the bathroom inspection port 5 The edge member 1 may be attached only to either one of 5a or the end surface 6a of the inspection lid 6.
The bathroom structure 10 of the present invention can be applied to any case of renovation and new construction.

A conventionally well-known structure can be adopted as a basic structure of the bathroom ceiling 4, the inspection port 5, and the inspection lid 6.
In the illustrated example, the bathroom ceiling 4 includes a ceiling base material 41 and an interior sheet 42 attached to the surface of the ceiling base material 41. The ceiling base material 41 is a basic structural material of the bathroom ceiling 4 and is a plate-like member. The ceiling base material 41 is formed using, for example, a steel plate coated with vinyl chloride, a plaster board, a resin plate such as a fiber reinforced resin, a tile, a stone plate, a wooden board, or the like. As the interior sheet 42, a synthetic resin sheet such as a vinyl chloride resin can be used. The interior sheet 42 is usually bonded to the surface of the ceiling base material 41 using an adhesive. The interior sheet 42 decorates and protects the surface of the ceiling base material 41 and prevents water vapor from condensing and adhering to the surface of the ceiling base material 41. The surface of the interior sheet 42 constitutes the surface of the bathroom ceiling 4.
The inspection port 5 is an opening formed by cutting out a part of the ceiling base material 41 of the bathroom ceiling 4. The plan view shape of the inspection port 5 is not particularly limited, and examples thereof include a square or a rectangle.

  The inspection lid 6 includes a lid base material 61, an interior sheet 62 attached to the surface of the lid base material 61, and a locking portion 63 provided on the back side of the lid base material 61. The lid base material 61 is formed in a shape that fits into the inspection port 5. As the lid base material 61, the same material as the ceiling base material 41 can be used, and the lid base material 61 is usually formed of the same kind of material as the ceiling base material 41. The interior sheet 62 of the inspection lid 6 can be the same as the interior sheet 42 of the ceiling base material 41, and the interior sheet 62 of the inspection lid 6 is usually the same type as the bathroom ceiling 4. The surface of the interior sheet 62 constitutes the surface of the inspection lid 6. The locking portion 63 extends outward from the peripheral edge of the lid base material 61. The locking portion 63 is locked to the back surface of the ceiling base material 41 when the inspection lid 6 is fitted into the inspection port 5 and prevents the inspection lid 6 from falling. The locking portion 63 is made of, for example, a plate-like member, and fixes the member to the lid base material 61 so that the edge of the plate-like member extends outward from the peripheral edge of the lid base material 61. Is provided.

The end surface 6 a of the inspection lid 6 is an outer surface of the lid base material 61 and is a surface along the thickness direction of the lid base material 61. The inspection lid 6 is within the range surrounded by the end face 6a. The edge of the interior sheet 62 attached to the lid base material 61 substantially coincides with the end surface 6 a of the inspection lid 6.
One edge member 1 is engaged with the end surface 6 a of the inspection lid 6 by engaging the engaging projection 3 with the surface portion 6 b around the inspection lid 6 and affixing the affixing wall 2 to the end surface 6 a of the inspection lid 6. It is attached. The surface portion 6 b around the inspection lid 6 is a surface near the corner portion including the substantially right-angled portion that is the boundary between the surface of the inspection lid and the end surface among the surfaces of the inspection lid 6. The surface of the inspection lid 6 when the interior sheet 62 is provided is the surface of the interior sheet 62, and the surface of the inspection lid 6 when the interior sheet is not provided is the surface of the lid base material 61. It is.
Specifically, as shown in FIG. 6, the double-sided adhesive tape 7 is affixed to the affixing surface 21 of the affixing wall 2 of the edge member 1. While the engagement surface 31 of the locking projection 3 of the edge member 1 is in contact with the surface portion 6 b around the inspection lid 6, the attachment surface 21 of the application wall 2 is connected to the end surface of the inspection lid 6 through the double-sided adhesive tape 7. Adhere to 6a. In addition, the sticking means of the edge member 1 is not restricted to the double-sided adhesive tape 7, You may use an adhesive agent (not shown). Further, the object to be pasted by the pasting means is not limited to the pasting surface 21, and if necessary, an adhesive may be applied to the engaging surface 31, and the pasting surface 21 and the engaging surface 31 may be adhered to the inspection lid 6. Good.
Since the edge member 1 has flexibility, the edge member 1 can be easily bent along the corner of the inspection lid 6 and attached to the entire end surface of the inspection lid 6 so as to be wound around. In addition, since the affixing surface 21 and the engaging surface 31 of the edge member 1 are substantially perpendicular, the engaging surface 31 is a surface portion even after the affixing wall 2 is affixed to the end surface 6 a of the inspection lid 6. 6b is in close contact with each other, and a gap is hardly formed between the engagement surface 31 and the surface portion 6b.

Further, the end surface 5 a of the inspection port 5 is a surface along the thickness direction of the ceiling base material 41 facing the opening of the ceiling base material 41. The inspection port 5 is within the range surrounded by the end face 5a. The edge of the interior sheet 42 affixed to the ceiling base material 41 substantially coincides with the end surface 5 a of the inspection port 5.
One edge member 1 is engaged with the end surface 5a of the inspection port 5 by engaging the locking projection 3 with the surface portion 5b around the inspection port 5 and attaching the affixing wall 2 to the end surface 5a of the inspection port 5. It is attached. In addition, the surface part 5b around the inspection port 5 is a corner vicinity surface including a substantially right-angled part which is a boundary between the surface of the bathroom ceiling and the end surface of the inspection port among the surfaces of the bathroom ceiling. Note that the surface of the bathroom ceiling when the interior sheet 42 is provided is the surface of the interior sheet 42, and the surface of the bathroom ceiling where the interior sheet is not provided is the surface of the ceiling base material 41.
The attachment method of the edge member 1 to the inspection port 5 can use sticking means, such as a double-sided adhesive tape 7 and an adhesive, similarly to the inspection lid 6.
Since the edge member 1 has flexibility, the edge member 1 can be easily bent along the corner of the inspection port 5, and can be attached to the entire end surface of the inspection port 5 so as to fit inside. Further, since the affixing surface 21 and the engaging surface 31 of the edge member 1 are substantially perpendicular, the engaging surface 31 is a surface portion even after the affixing wall 2 is affixed to the end surface 5 a of the inspection port 5. It adheres closely to 5b, and it becomes difficult to produce a clearance gap between the engaging surface 31 and the surface part 5b.

According to the bathroom structure 10 of the present invention, the end surface 5a of the inspection port 5, the end surface 6a of the inspection lid 6, and the edge of the interior sheet 42 are concealed by the edge member 1, so that the appearance around the inspection port is improved. Furthermore, since the edges of the interior sheets 42 and 62 are protected by the edge member 1, it is difficult for water vapor and moisture to enter between the edges of the interior sheets 42 and 62 and the surface of the bathroom ceiling 4 or the surface of the inspection lid 6. Thus, peeling of the interior sheets 42 and 62 can be effectively prevented.
Furthermore, in the bathroom structure of the present invention, the adhesive wall 2 of the edge member 1 is interposed in the gap between the end face 5a of the inspection port 5 and the end face of the inspection lid 6, so that the gap becomes small. Intrusion can be suppressed.
In general, when the interior sheet is attached to the ceiling base material and the lid base material, the interior sheet must be accurately cut so that the edge of the interior sheet matches the end surface of the inspection port and the end surface of the inspection lid. . In this respect, since the bathroom structure 10 of the present invention conceals the edges of the interior sheets 42 and 62 by the edge member 1, the edges of the interior sheets 42 and 62 are accurately placed on the end surface 5 a of the inspection port 5 and the end surface 6 a of the inspection lid 6. Since it is not necessary to match well, the interior sheets 42 and 62 can be easily constructed.
Further, the edge member 1 of the present invention can be curved along the end face shape of the inspection port 5 or the end face shape of the inspection lid 6, and a sticking means such as a double-sided adhesive tape 7 without using a dedicated tool. It can be easily attached using.

  The edge member and bathroom structure of the present invention are not limited to the above-described one embodiment, and can be variously changed within the range intended by the present invention. Hereinafter, although other embodiment of this invention is described, description is abbreviate | omitted about the structure, effect, and usage method similar to the said embodiment, and a term and a code | symbol are used as it is.

[Other Embodiments]
In the edge member 1 of the above one embodiment, the locking projection 3 protrudes only on one side of the sticking wall 2. For example, as shown in FIG. 81 and 82 may protrude on opposite sides. Hereinafter, one locking projection 81 is referred to as a first locking projection 81, and the other locking projection 82 is referred to as a second locking projection 82.
Specifically, the edge member 1 has a first locking projection 81 projecting from the lower end of the sticking wall 2 toward one side of the sticking wall 2 and second toward the other side of the sticking wall 2. A locking convex portion 82 is projected. The 1st latching convex part 81 protrudes in the sticking surface 21 side of the sticking wall 2, and is equivalent to the latching convex part 3 of the edge member 1 of the said embodiment. The 2nd latching convex part 82 protrudes in the exposed surface 22 side of the sticking wall 2. As shown in FIG. The protruding height of the first locking projection 81 is the same as the protruding height B of the locking projection 3 of the above embodiment. The protruding height of the second locking projection 82 is preferably larger than the length between the end surface 5a of the inspection port 5 and the end surface 6a of the inspection lid 6, that is, the gap between the inspection port 5 and the inspection lid 6. .

The edge member 1 having the first and second locking projections 81 and 82 is attached to the end surface 5a of the inspection port 5 using a double-sided adhesive tape 7 as shown in FIG. At this time, the engagement surface 811 of the first locking projection 81 is locked to the surface portion 5b around the inspection port 5, and the tip of the engagement surface 821 of the second locking projection 82 is It is in contact with or close to the surface portion 6b around the inspection lid 6. That is, the affixing surface 21 of the affixing wall 2 of the edge member 1 is affixed to the end surface 5 a of the inspection port 5 while the engaging surface 811 of the first locking projection 81 is engaged with the surface portion 5 b around the inspection port 5. As a result, the tip of the engagement surface 821 of the second locking projection 82 is in contact with or close to the surface portion 6b around the inspection lid 6, and the gap X between the inspection port 5 and the inspection lid 6 is the second locking projection. The bathroom structure 10 is closed by the portion 82. The proximity is preferably 2 mm or less between the engagement surface 821 and the surface portion 6b of the second locking projection 82, for example.
In the bathroom structure 10, since the gap X between the inspection port 5 and the inspection lid 6 is concealed by the second locking projection 82, not only the appearance is improved, but also bathroom vapor passes through the gap X to the ceiling. Can be effectively prevented from entering. In particular, since the edge member 1 having the first and second locking projections 81 and 82 is formed of a flexible material, it is possible to more effectively prevent the entry of steam or the like through the gap X. In addition, when the inspection lid 6 is attached to the inspection opening 5 to which the edge member 1 is attached, the flexible edge member 1 functions as an impact buffer, so that the inspection lid 6 can be prevented from being damaged. In addition, the end face of the interior sheet 42 and the gap X can be concealed at the same time by simply sticking one edge member 1 to the surface portion 5b around the inspection port 5, thereby simplifying the construction and shortening the construction time. can do.

  In the edge member 1 of the above-described one embodiment, the affixing surface 21 of the affixing wall 2 is formed in a flat shape. For example, as shown in FIG. It may be formed. By forming the small protrusions 23 in this way, the adhesive enters the recesses between the adjacent small protrusions 23, so that the adhesive strength of the affixing surface 21 to the end surface 5 a of the inspection port 5 can be improved. In particular, when the adhesive is used as the sticking means, the improvement of the adhesive strength can be expected. In addition, the protrusion height of the small protrusion part 23 is 0.05 mm-0.2 mm, for example.

  Moreover, as shown in FIG. 10, the latching convex part 3 may be formed so that the thickness of the latching convex part 3 may become large gradually as it goes to the sticking wall 2 from the front-end | tip part 3a. Such a shape is formed, for example, such that the outer surface 32 of the locking convex portion 3 extends obliquely downward from the distal end portion 3 a toward the sticking wall 2. The edge member 1 having such a locking projection 3 is made of a flexible material, so that the tip 3a of the locking projection 3 is easily elastically deformed and easily stretched. Therefore, when the end surface 6a of the inspection lid 6 is affixed to the edge member 1, the distal end portion 3a of the locking projection 3 extends at the corner of the end surface 6a of the inspection lid 6. Can be installed neatly.

Further, in the edge member 1 of the above-described one embodiment, the locking projection 3 is formed in a semicircular shape in cross section. For example, as shown in FIG. It may be formed in a trapezoidal shape. The locking convex portion 3 has a first thin portion 331 whose thickness gradually decreases from the tip portion 3a toward the affixing wall 2, and a wall thickness that gradually decreases from the affixing wall 2 toward the tip portion 3a. It consists of a second thin portion 332 and a thick portion 333 interposed between the first thin portion 331 and the second thin portion 332. The edge member 1 according to one embodiment of FIG. 2 is also conceptually sandwiched between the first thin portion, the second thin portion, and the two thin portions, similarly to the edge member 1 of FIG. And a thick part interposed.
By forming the edge member 1 from a flexible material, the first thin portion 331 and the second thin portion 332 are easily elastically deformed and easily stretched. Therefore, when the edge member 1 is attached to the end surface 6a of the inspection lid 6, the first thin portion 331 of the locking projection 3 extends at the corner of the end surface 6a of the inspection lid 6, and the edge member 1 is connected to the inspection port. 5, the second thin portion 332 of the locking projection 3 extends at the corner of the end surface 5 a of the inspection port 5, so that the edge member 1 is neatly attached in any case. be able to.

  In addition, the inspection lid 6 of the above-described one embodiment has a structure that is locked to the back surface of the ceiling base material 41 at the locking portion 63 when fitted to the inspection port 5, but is not limited thereto. For example, as shown in FIG. 12, an inverted U-shaped locking recess 64 is formed at the peripheral edge of the lid base material 61, and a U-shaped locked recess 44 is formed at the peripheral edge of the ceiling base material 41. The inspection lid 6 may be held by the inspection port 5 by fitting the locking recess 64 and the locked recess 44.
