Description

The present invention relates to a surrounding edge cover and a surrounding edge cover mounting structure.

Traditionally, in building interior construction work, etc., after finishing walls and ceilings, the purpose was to cover up gaps that occurred where the walls and ceilings fit together, and unfinished portions that occurred at the edges of wall materials or ceiling materials. It is common practice to construct a rim around the area where the wall and ceiling fit together.

The ceiling material is generally made of rock wool or wood fiberboard, and the surface is colored white.For the walls, decorative sheet material is pasted on a base material such as gypsum board. It is done by putting it on and finishing it. The surrounding edge has a covering part that contacts the surface (lower surface) of the ceiling material, and is installed by being attached to the ceiling base, wall base, wall material, etc. with the covering part covering the surface of the ceiling material.

When the surrounding edge is constructed in this way, if there is a gap between the surrounding edge and the surface of the ceiling material, that gap will appear as a shadow. In other words, when indoor lighting or sunlight from a window hits the edge of the ceiling, the light is blocked by the corner of the edge of the cover, creating areas in the room that are not exposed to light and creating shadows on the surface of the ceiling material. This results in an unnatural appearance. In particular, if the ceiling material has an uneven pattern on its surface, a large gap will be created between the recess and the surrounding edge, so that the shadow appearing within the recess will be noticeable.

Therefore, as shown in Patent Document 1, the applicant of the present application has conventionally provided a transparent portion integrally with a base material of an opaque material that comes into contact with the wall material as a surrounding edge, and brought the transparent portion into contact with or with the ceiling material. We suggest placing them in close proximity. In this device, the light incident on the surrounding edge is transmitted through the transparent portion as it is, thereby preventing the formation of shadows on the surface of the ceiling material or in its recesses.

Patent No. 3927773

By the way, the surrounding edge of Patent Document 1 is a dedicated surrounding edge for preventing shadows, so if the existing surrounding edge has already been constructed, it must be removed and replaced with a new dedicated surrounding edge. This makes the work of replacing it troublesome.

In particular, it is often the case that a black shadow appearing on the ceiling surface near the surrounding edge becomes visible only after the ceiling has been installed, so it would be advantageous to have retrofitted parts.

The present invention has been made in view of these points, and its purpose is to improve the surrounding structure of the surrounding edge so that by simply adding new members to the existing surrounding edge, it is possible to eliminate shadows on the ceiling material. The goal is to prevent it from happening.

In order to achieve the above object, the present invention provides a cover made of a transparent or opaque material that can be attached later to the existing surrounding edge, and places a part of the cover inside the corner between the surrounding edge and the ceiling material. This arrangement prevents shadows from forming due to the translucent effect of the cover itself.

Specifically, the first invention is directed to a circumferential edge cover that is constructed at a fitting portion between a wall and a ceiling of a building and is attached to a circumferential edge that has a covering portion that covers an end of a ceiling material in the ceiling. It is.

The surrounding edge cover includes a mounting portion attached to the surrounding edge covering portion, and is integrally formed with this mounting portion, and is disposed in a corner between the surrounding edge covering portion and the ceiling material covered by the covering portion. and a cover portion, and at least the cover portion is made of a transparent or translucent material.

In this first invention, for a surrounding edge constructed at a fitting part between a wall and a ceiling of a building, a surrounding edge cover is attached to a covering part that covers an end of the ceiling material at its attachment part. It is attached. A cover part is integrally formed with the mounting part of the surrounding edge cover, and when the cover part is attached to the surrounding edge of the mounting part, the cover part is located in the corner between the surrounding edge covering part and the ceiling material covered by the cover part. Arranged to be filled. At least this cover part is made of a transparent or semi-transparent material, so the light incident on the surrounding edge passes through the cover part of the surrounding edge cover and enters the corner between the surrounding edge covering part and the ceiling material. Even if there is a recess on the surface of the ceiling material, the transmitted light will reach into the recess, and this will cause shadows to be seen in the corner between the surrounding edge covering and the ceiling material, or in the recess on the surface of the ceiling material. will no longer occur.

Since the surrounding edge cover is attached to the covering portion of the surrounding edge, the above shadow prevention effect can be obtained by simply attaching the surrounding edge cover to the surrounding edge without changing the structure of the surrounding edge. Therefore, there is no need to replace it with a dedicated surrounding edge that has a shadow prevention effect, and the existing surrounding edge can easily exhibit a shadow prevention effect.

In particular, black shadows that appear on the ceiling surface are often noticeable only after the ceiling is installed, so even in such cases, it would be very advantageous to have a surrounding edge cover like the one described above as a retrofitted part.

In addition, if the entire surrounding edge cover (attachment part and cover part) is made of transparent or semi-transparent material, the attachment part and the cover part can be manufactured from the same material, and the surrounding edge cover can be manufactured easily at low cost. I can do it.

A second invention is the circumferential edge cover according to the first invention, in which the mounting portion is elastically deformable and has an engagement groove provided on the upper surface to be externally fitted and attached to the strip-like cover portion of the circumferential edge. It consists of a plate-like body with a U-shaped cross section. The inner width of the engaging groove is smaller than the outer width of the surrounding edge cover, and when the surrounding edge cover is fitted into the engaging groove, the mounting portion is elastically deformed and the surrounding edge is moved. It is configured to be attached to the edge cover. Moreover, the cover part is comprised by the side wall on the opposite side to a wall part among the side walls which the said engagement groove opposes.

In this second invention, the mounting part is a plate-shaped body having a U-shaped cross section, and the cover part is constituted by one side wall of the engagement groove provided on the top surface of the plate body, and the cover part and the mounting part are connected to each other. Some parts can be used together.

In addition, since the inner width of the engagement groove is smaller than the outer width of the surrounding edge cover, when the circumferential edge cover is fitted into the engagement groove, the mounting portion elastically deforms and the surrounding edge covers. Attached to the cover of the With this mounting structure, the surrounding edge cover can be attached by simply pressing it against the existing surrounding edge, and the mounting part will be elastically deformed.Compared to adhesives or double-sided tape, the installation can be done with one touch. Simple and easy to do.

A third invention is characterized in that in the circumferential edge cover of the first or second invention, at least the cover portion is made of a translucent material. A semi-transparent material refers to a material having a light transmittance of less than 100%, for example.

In this third invention, since at least the cover portion of the surrounding edge cover is made of a translucent material, it is possible to prevent adhesive seepage or foreign matter (dust or dirt) between the ceiling material and the surrounding edge or within the surrounding edge. Even if they are attached, they can be hidden, and the ceiling base etc. will also be hidden, making them less noticeable.

Furthermore, if the mounting part is also made translucent, the translucent surrounding edge cover itself can be seen independently, creating a unique design that cannot be obtained with a transparent surrounding edge cover.

In addition, due to the accuracy of the construction of the ceiling material, even if the cross section is located within the surrounding edge cover or the corner of the ceiling material, the cross section is made less noticeable by the cover and can be easily seen. It is possible to reduce the degree of

A fourth invention is that in the circumferential edge cover according to any one of the first to third aspects, the outer surface of the cover portion of the circumferential edge cover is inclined downwardly toward the wall. It is characterized by Here, the term "slanted outer surface" includes not only a planarly inclined surface but also an arcuate and inclined surface.

In this fourth invention, since the outer surface of the cover part is inclined, this outer surface faces a space such as an indoor space surrounded by a wall part and a ceiling part, and the light incident on the surrounding edge of the cover part is slanted. The light passes through the cover part from the outside smoothly, and it is possible to more effectively prevent shadows from forming in the corners and recesses between the surrounding cover part and the ceiling material.

A fifth invention is a surrounding edge cover mounting structure that is attached to the surrounding edge of the surrounding edge cover of any one of the first to fourth inventions, and in this structure, the surrounding edge is a base member that is attached to a ceiling base. and a cover member attached to the base member, the cover member has a band-shaped cover portion that sandwiches the end of the ceiling material between the base member, and the mounting portion of the surrounding edge cover is attached to the cover member. It is characterized by being attached to the cover part of the member.

In the fifth invention, when the surrounding edge is being constructed, the base member is attached to the ceiling base, and when the cover member is attached to the base member, there is a gap between the band-like covering portion of the cover member and the base member. The end portion of the ceiling material is sandwiched between the ends of the ceiling material, and a corner portion is formed between the covering portion and the ceiling material. By attaching the circumferential edge cover to the circumferential edge covering portion, the cover portion of the circumferential edge cover is disposed within the corner between the cover portion and the ceiling material. In this case as well, the same effects as in the first invention can be obtained.

As explained above, according to the present invention, a circumferential edge cover attached to the covering portion is provided for the circumferential edge covering the end portion of the ceiling material by the covering portion, and at least the cover portion of the circumferential edge cover is made transparent or translucent. By placing the material in the corner between the surrounding edge covering and the ceiling material, you can simply attach the surrounding edge cover to the existing surrounding edge and remove the corner between the surrounding edge covering and the ceiling material. It is possible to prevent shadows from forming in the recesses on the surface of ceiling materials and ceiling materials, and it is possible to obtain the effect of preventing shadows around the surrounding edges with a simple structure.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. The following description of the embodiments is merely illustrative in nature and is in no way intended to limit the present invention, its applications, or its uses.

[Embodiment 1]
1 and 2 show Embodiment 1 of the present invention, W is a wall inside a building, W1 is the wall base, C is the ceiling inside the room, C1 is the ceiling base, and the wall base W1 is A wall material W2 is constructed, and a ceiling material C2 (ceiling board) is constructed on the ceiling base C1. A circumferential edge A is constructed around the area where the wall portion W and the ceiling portion C fit together. The ceiling material C2 may or may not have an uneven pattern on its lower surface.

(around)
The above-mentioned surrounding edge A will be explained. This surrounding edge A includes a base member 1 attached to the ceiling base C1 and a cover member 10 attached to the base member 1. These are elongated members made of extruded resin and have the same length. The base member 1 is made of, for example, ABS resin, and the cover member 10 is made of, for example, PVC resin.

The base member 1 includes a band-shaped base 2, which has a wide plate shape with the width direction being the direction in which it approaches and separates from the wall W, and the upper surface of the base 2 on one side in the width direction. For example, a double-sided tape 7 (shown only in FIG. 1) is pasted on. A plate-shaped support portion 3 is integrally provided on the lower surface of the base portion 2 at a substantially central position in the width direction, and is integrally protruded so as to hang down. It is inclined toward the side, and a step-like engagement portion 4 is formed at the upper end of one side surface (the surface on the wall portion W side) of this inclined portion. Further, a positioning stopper portion 5 that projects horizontally is integrally provided on the other side surface (the surface opposite to the wall portion W) of the upper half above the inclined portion.

On the other hand, the cover member 10 has a cover part 11 for covering the end of the ceiling material C2 installed on the ceiling part C. The cover part 11 is a strip-shaped member extending in the horizontal direction with the width direction being the direction in which the cover part 11 approaches and leaves the wall part W, and the lower surface thereof is a horizontal plane. At one end of the width direction of the cover part 11 (the end on the side of the wall part W), there is an outer vertical wall part 12 extending toward the upper side, and at approximately the center position of the cover part 11 in the width direction, there is an outer vertical wall part 12 extending toward the upper side. An inner vertical wall portion 13 extending parallel to the outer vertical wall portion 12 is formed integrally with the outer vertical wall portion 12, and both vertical wall portions 12, 13 and one side of the cover portion 11 are continuous with each other in a U-shaped cross section. As a result, an engaging groove 14 is formed that opens upward, with both vertical wall portions 12 and 13 serving as groove side walls, and one side portion of the cover portion 11 serving as a bottom wall. Of both side surfaces in the engagement groove 14, a step-shaped locking portion 15 is formed on the side surface on the outer vertical wall portion 12 side, while a step-shaped locking portion 15 is formed on the side surface on the inner vertical wall portion 13 side. A protruding portion 16 is integrally provided. The upper end of the outer vertical wall portion 12 is bent at right angles and continuous with a horizontal portion 17 extending horizontally.

The other side of the cover part 11 (the side opposite to the wall part W) protrudes horizontally from the bottom of the engagement groove 14, and its tip is bent upward at a right angle and then bent at a right angle towards the mounting part. The upper end of the bent tip portion is a horizontal plane, and a vertical surface 11a extending in the vertical direction is formed at this tip portion.

Then, as shown in FIG. 2, the base 2 is attached to the ceiling base C1 using the double-sided tape 7 attached to the upper surface of the base 2 of the base member 1, and the screw V is passed through the other side in the width direction of the base 2. The base member 1 is attached to a predetermined position on the ceiling base c1 by driving the base member 1 into the ceiling base C1. After constructing the ceiling material C2 on the ceiling base C1 and placing the end of the ceiling material C2 on the lower surface of the base 2 of the base member 1, the cover member 10 is pushed up and moved to the base member 1 side, and the cover member 10 is moved to the base member 1 side. The support part 3 of the base member 1 is fitted into the engagement groove 14 of the base member 1, the locking part 15 in the engagement groove 14 is engaged with the engagement part 4 of the base member 1, and the protrusion part 16 is fitted into the support part 1. The cover member 10 is attached to the base member 1 in a locked state by being pressed against the other side surface of the inclined portion of the cover member 3 . In the attached state, the horizontal portion 17 overlaps the lower surface of one widthwise side of the base portion 2 of the base member 1, and the upper end of the inner vertical wall portion 13 is regulated by the positioning stopper portion 5 of the base member 1, so that the upper end of the cover member 10 Movement will be regulated. In addition, the cover member 10 sandwiches the end of the ceiling material C2 with the base member 1 with the band-shaped covering portion 11, and the horizontal surface of the upper end of the tip of the covering portion 11 is placed on the lower surface of the end of the ceiling material C2. A corner D is formed by the vertical surface 11a of the tip and the lower surface of the end of the ceiling material C2.

A surrounding edge cover B according to an embodiment of the present invention is attached to such a surrounding edge A, and a surrounding edge cover mounting structure is formed by the surrounding edge A and the surrounding edge cover B attached to the surrounding edge A. It is formed.

(Surrounding edge cover)
The circumferential edge cover B is a long extruded material that is attached to the cover portion 11 of the circumferential edge A from below, and has the same length as the circumferential edge A, and has a U-shaped cross section as a whole. There is. Specifically, the surrounding edge cover B includes a mounting portion 20 having a U-shaped cross section that is attached to the covering portion 11 of the surrounding edge A, and a cover portion 23 that is integrally formed with this mounting portion 20. 20 and the cover portion 23 (the entire surrounding edge cover B) are made of an elastically deformable material.

The attachment part 20 is a long plate material, and an engagement groove 21 is formed continuously over the entire length of the attachment part 20 on the upper surface thereof. This engagement groove 21 is a groove whose inner bottom is flat, and the inner width (width between the inner surfaces) of the engagement groove 21 is the outer width (the outer vertical wall) of the cover 11 of the surrounding edge A. The groove depth is approximately the same as the height of the tip of the cover 11 (its vertical surface 11a). The fitting groove 21 is externally fitted to the cover part 11 of the circumferential edge A while elastically deforming the attaching part 20, so that it can be attached to the cover part 11.

Although not shown, when the mounting portion 20 is not attached to the cover portion 11 of the surrounding edge A, a view corresponding to the proximal end side of the cover portion 11 of the two opposing side walls of the engagement groove 21 is provided. 1 and 2, the relationship between the right side wall (the side wall located on the wall W side) and the outer vertical wall portion 12 of the covering portion 11 located at a position corresponding to this side wall is as follows: While the vertical wall portion 12 extends in the up-down direction (vertical direction), the former side wall is inclined at a slight angle (for example, 2 to 3 degrees) toward the inside of the engagement groove 21 toward the upper side. As a result, the width of the opening side of the engagement groove 21 is slightly narrower than the width of the inner bottom of the groove, and when the cover part 11 is fitted into the engagement groove 21, the cover of the mounting part 20 is The side wall on the base end side of the portion 11 is brought into close contact with the outer vertical wall portion 12 of the cover portion 11 in a press-contact state, so that the attachment portion 20 is difficult to come off from the cover portion 11. When the side wall is inclined in this way, it is also possible to make the side wall not the entire side wall but only the inner surface thereof (the groove inner surface of the engagement groove 21) an inclined surface.

In addition to this fixing structure by fitting, fixing by double-sided tape or adhesive may also be used.

Further, the cover portion 23 is integrally formed with the mounting portion 20 of the surrounding edge cover B. In the mounting part 20, this cover part 23 is composed of a side wall corresponding to the distal end side of the cover part 11 (a side wall located on the opposite side to the wall part W) of the two opposing side walls of the engagement groove 21. There is. When the mounting portion 20 of the circumferential edge cover B is attached to the circumferential edge A by fitting the engagement groove 21 with the cover portion 11 of the circumferential edge A, the upper end surface of the cover portion 23 is attached to the circumferential edge A. It is arranged flush with the horizontal plane of the upper end of the tip of the cover part 11, and is arranged so as to be filled in the corner D between the cover part 11 of this surrounding edge A and the ceiling material C2 covered by the cover part 11. be done. The outer surface 23a of the cover portion 23 is inclined downward toward the wall W side. Specifically, this outer surface 23a is an arcuate surface that bulges outward and is inclined. Note that the outer surface 23a of the cover portion 23 may be an inclined plane that is inclined in a plane.

The mounting portion 20 and the cover portion 23 are made of a transparent material with a light transmittance of 100% or a translucent (ground glass-like) material with a light transmittance of less than 100%, preferably a translucent material. As the material of this surrounding edge cover B (attachment part 20 and cover part 23), for example, vinyl chloride resin, ABS, PP, PE, acrylic resin, etc. are used. Note that both the mounting portion 20 and the cover portion 23 do not need to be made of transparent or semi-transparent materials; only the cover portion 23 may be made of a transparent or semi-transparent material, and the mounting portion 20 may be made of an opaque material.

Therefore, in this embodiment, when the surrounding edge A is constructed at the fitting part between the wall part W and the ceiling part C of the building, the covering part 11 covering the end of the ceiling material C2 of the surrounding edge A is The mounting portion 20 of the surrounding edge cover B is attached. That is, the mounting portion 20 of the surrounding edge cover B has a U-shaped cross section and is made of an elastically deformable material, and an engagement groove 21 that is open upward is formed on its upper surface. The inner width of this engaging groove 21 is slightly smaller than the outer width of the cover part 11 of the surrounding edge A, so when the mounting part 20 of the surrounding edge cover B is pressed against the surrounding edge A, the opening of the engaging groove 21 is opened. When the mounting part 20 is deformed so as to expand a little and the cover part 11 of the surrounding edge A is fitted into the inside thereof, the cover part 11 is pushed into the engagement groove 21 due to the elastic deformation of the mounting part 20. The surrounding edge cover B is attached to the covering portion 11 of the surrounding edge A and fixed. With this mounting structure, the surrounding edge cover B can be attached by simply pressing it against the surrounding edge A by elastic deformation of the mounting portion 20, which is easier to attach than using adhesive or double-sided tape. Installation can be done simply and easily with one touch.

A cover part 23 is integrally formed in the mounting part 20 of the surrounding edge cover B, and this cover part 23 is located at the tip of the cover part 11 of the two opposing side walls of the engagement groove 21 in the mounting part 20. Since the cover part 23 is composed of a side wall corresponding to the side (the side wall located on the opposite side to the wall part W), when the surrounding edge cover B is attached to the surrounding edge A as described above, the cover part 23 is It is arranged so as to be filled in the corner D between the vertical surface 11a at the tip of the cover part 11 of A and the ceiling material C2 covered by the cover part 11. Since the mounting part 20 and the cover part 23 of the surrounding edge cover B are made of transparent or semi-transparent material, the light incident on the surrounding edge A passes through the cover part 23 of the surrounding edge cover B as it is, and is transmitted to the surrounding edge A. It reaches into the corner D between the cover part 11 and the ceiling material C2. Therefore, when the ceiling material C2 has a smooth surface without any depressions due to an uneven pattern on its surface, the transmitted light not only reaches the surface of the ceiling material C2 in the corner D, but also has an uneven pattern on the surface. Even if the ceiling material C2 has a recessed portion, the transmitted light that reaches the corner D will also reach the recessed portion located within the corner D. This prevents shadows from being formed at the corner D between the covering portion 11 of the surrounding edge A and the ceiling material C2, and within the recessed portion of the surface of the ceiling material C2, so that no unnatural appearance occurs.

Moreover, since the outer surface 23a of the cover part 23 of the circumferential edge cover B is inclined, this outer surface 23a faces a space such as an indoor space surrounded by the wall part W and the ceiling part C, so that no light is incident on the circumferential edge A. The light transmitted from the outer surface 23a to the cover part 23 of the surrounding edge cover B is transmitted smoothly from the outer surface 23a, and shadows are more effectively prevented from forming at the corner D or recess between the covering part 11 of the surrounding edge A and the ceiling material C2. It can be prevented.

Since the surrounding edge cover B is attached to the covering portion 11 of the surrounding edge A, the above shadow prevention effect can be obtained by simply attaching it to the surrounding edge A without changing the structure of the surrounding edge A. become. Therefore, there is no need to replace it with a dedicated surrounding edge that has a shadow prevention effect, and the existing surrounding edge A can easily have a shadow prevention effect.

In particular, the black shadow that appears on the ceiling C is often noticeable (noticed) only after the ceiling C is actually constructed due to various changes in indoor light, light from windows, weather, etc. However, it will be very advantageous if the surrounding edge cover B according to this embodiment is used as a retrofitted part.

Furthermore, since the entire surrounding edge cover B (attachment section 20 and cover section 23) is made of the same transparent or translucent material, it is sufficient to manufacture the attachment section 20 and cover section 23 from the same material, and the surrounding edge cover B can be It can be easily manufactured at low cost.

Further, the surrounding edge cover B has an engagement groove 21 in the attachment part 20, and a cover part 23 is formed on one side wall of the engagement groove 21, so that the cover part 23 can be attached easily. A part of the section 20 can also be used.

Furthermore, if the mounting part 20 and cover part 23 of the surrounding edge cover B are made of a translucent material, it is assumed that adhesive seepage or foreign matter (dust) between the ceiling material C2 and the surrounding edge A or within the surrounding edge A is Even if dirt or dust) is attached, it can be hidden, and the ceiling base C1 etc. are also hidden and become less noticeable. In addition, the translucent surrounding edge cover B itself can be seen independently, and a unique design feeling that cannot be obtained with the transparent surrounding edge cover B can be created. Furthermore, due to the accuracy during construction of the ceiling material C2, even if the cross section is located within the cover portion 11 of the surrounding edge A or the corner D with the ceiling material C2, the cross section may be removed by the cover portion 23. It is possible to make it less noticeable and reduce the degree of appearance.

[Embodiment 2]
FIG. 5 shows a second embodiment of the present invention (in each of the following embodiments, the same parts as in FIGS. 1 to 4 are given the same reference numerals and detailed explanations are omitted), and different types of parts are shown. An edge cover B is attached around the edge A1.

The surrounding edge A1 is different from that of the first embodiment, and has a structure in which the base member 1 and the cover member 10 are integrated, instead of being a combination of the base member 1 and the cover member 10 as in the first embodiment. Specifically, the surrounding edge A1 includes a band-shaped base 2 that is attached to the ceiling base C1 with double-sided tape, screws V, etc., and a band-shaped base 2 that hangs down at a position near the wall W2 at the widthwise middle part of this base 2. A support part 3 protruding from the support part 3 and a band-shaped cover part 11 that is continuous with the lower end of the support part 3 and extends horizontally from the lower end of the support part 3 in a direction away from the wall part W are integrally formed. For example, it is made of extruded resin material. The cover part 11 is similar to that in Embodiment 1, and its tip is bent upward at a right angle and then bent at a right angle toward the support part 3, and the upper end of the tip is a horizontal surface. A vertical surface 11a is formed along the vertical direction, and the height of the vertical surface 11a is, for example, 3 mm.

Note that, unlike in Embodiment 1, the surrounding edge A1 is attached to the ceiling base C1 in such a way that, when the wall material W2 is installed on the wall base W1, the widthwise end of the base 2 comes into contact with the surface of the wall material W2. can be attached to.

On the other hand, the surrounding edge cover B is the same as that in Embodiment 1, and is a long extrusion molded material attached to the cover part 11 of the surrounding edge A1 from below, has the same length as the surrounding edge A1, and has the same length as the surrounding edge A1. It has a U-shaped cross section. That is, the surrounding edge cover B includes a mounting portion 20 having a U-shaped cross section and attached to the covering portion 11 of the surrounding edge A1, and a cover portion 23 integrally formed with this mounting portion 20, and these mounting portions 20 and the cover. The portion 23 (the entire surrounding edge cover B) is made of an elastically deformable material.

An engagement groove 21 is continuously formed on the upper surface of the mounting portion 20 over the entire length of the mounting portion 20 . The inner width of this engagement groove 21 is slightly smaller than the outer width of the cover part 11 of the surrounding edge A1, and the groove depth is approximately the same as the height of the tip of the cover part 11 (its vertical surface 11a). The attachment part 20 is attached to the cover part 11 by externally fitting the engagement groove 21 into the cover part 11 of the surrounding edge A1 while elastically deforming the attachment part 20. In addition to this fixing structure by fitting, fixing by double-sided tape or adhesive may also be used.

Further, the cover portion 23 is integrally formed with the mounting portion 20. This cover portion 23 is constituted by a side wall corresponding to the distal end side of the cover portion 11 of the two opposing side walls of the engagement groove 21 in the attachment portion 20 . When the mounting portion 20 of the circumferential edge cover B is attached to the circumferential edge A1 by fitting the engagement groove 21 with the cover portion 11 of the circumferential edge A1, the cover portion 23 is connected to the cover portion 11 of the circumferential edge A1. The cover part 11 is disposed so as to fill the corner D between the cover part 11 and the ceiling material C2.

The mounting portion 20 and the cover portion 23 are made of a transparent material with a light transmittance of 100% or a semitransparent material with a light transmittance of less than 100%, preferably a semitransparent material. Both the attachment part 20 and the cover part 23 do not need to be made of transparent or translucent materials; only the cover part 23 may be made of a transparent or translucent material, and the attachment part 20 may be made of an opaque material.

The other configurations of this embodiment are the same as the first embodiment. Therefore, the second embodiment also provides the same effects as the first embodiment.

[Embodiment 3]

The circumferential edge A3 of this embodiment has a structure different from that of the third embodiment only in the covering portion 11 of the circumferential edge A2. That is, since the cover part 11 is continuous with the lower end of the support part 3, the circumferential edge A3 as a whole has a U-shaped cross section, but the cover part 11 is different from that of the third embodiment, and the tip The portion does not have a bent portion as in Embodiments 1 to 3, and the tip portion is a plate-shaped end portion having the same thickness as the other portions. As a result, the top surface of the tip becomes a horizontal plane, and a vertical surface 11a is formed along the vertical direction at the tip, and the height (thickness) of the vertical surface 11a is, for example, 1 mm.

On the other hand, the surrounding edge cover B2 is a long extrusion molded material that is attached to the cover part 11 of the surrounding edge A3 from below, as in the third embodiment, and has the same length as the surrounding edge A3. Like the one above, it has an L-shaped cross section as a whole. As a result, the circumferential edge cover B2 includes an attachment part 20 having an L-shaped cross section and attached to the cover part 11 of the circumferential edge A3, and a cover part 23 integrally formed with the attachment part 20. The mounting portion 20 and the cover portion 23 (the entire surrounding edge cover B2) may be made of either an elastically deformable material or a non-elastically deformable material.

An engagement stepped portion 22 is formed on the upper surface of the attachment portion 20, and the attachment portion 20 is attached to the cover portion 11 by fitting (engaging) this engagement step portion 22 to the cover portion 11 of the surrounding edge A3. . This mounting and fixing is done using double-sided tape or adhesive.
