Description

  The present invention relates to a corner covering member that covers a gap between two plate-like wall surface construction materials attached to a corner of a wall, and a corner structure including the corner covering member.

  The skirting board (or surrounding edge) is fixed to the vicinity of the floor (or ceiling) of the wall by gluing, nailing, or the like. For this reason, two skirting boards (or surrounding edges) are crossed in the corner of the wall. It is arranged. Conventionally, various corner covering tools have been proposed in order to cover the gap between two baseboards (or peripheral edges) attached to the corners of a wall (see Patent Documents 1 to 3).

In the corner covering tool disclosed in Patent Document 1, both end portions in the lateral direction are fixed to two baseboards (or surrounding edges) by adhesion using a double-sided tape, nailing, or the like.
When such a corner covering is attached by nailing, there is a problem that the aesthetic appearance is impaired because the head of the nail is exposed. In addition, when attached by adhesion using a double-sided tape, the strength of attachment is weaker than that of nailing, and there is a problem that the corner covering is easily dropped.

In order to solve these problems, the corner covering disclosed in Patent Document 2 has fitting protrusions formed on the inner sides of both lateral ends. Such a corner covering device is obtained by fitting a fitting projection from above (or below) into a fitting recess formed on the wall side of each of the two skirting boards (or peripheral edges). (Or a peripheral edge).
The corner covering tool disclosed in Patent Document 3 has a covering member that covers a gap between two baseboards or a peripheral edge, and an attachment member that is formed inside the covering member. ing. Such a corner covering device is fixed to two baseboards (or surrounding edges) by sandwiching the sandwiched portion of the attachment member between the two baseboards (or surrounding edges) and the wall. .

  By the way, the skirting board (or the peripheral edge) is generally formed using wood, a wooden member, or the like, and may expand and contract in the lateral direction in accordance with changes in temperature, humidity, and the like.

As disclosed in Patent Document 1, when a corner covering is directly fixed to two baseboards (or surrounding edges) by adhesion using a double-sided tape, the baseboard (or surrounding edges) expands and contracts. Accordingly, unnecessary external force is applied to the corner covering device and the double-sided tape. For this reason, the double-sided tape is peeled off and the corner covering device is easily dropped.
On the other hand, as disclosed in Patent Documents 1 and 2, the corner covering is directly fixed to the two baseboards (or the peripheral edges) by nailing or fitting between the fitting protrusion and the fitting recess. In such a case, the corner covering may be damaged by an unnecessary external force applied to the corner covering according to the expansion and contraction of the skirting board (or the peripheral edge).

In addition, in order to use the corner covering disclosed in Patent Document 2, it is necessary to form a fitting recess in two baseboards (or surrounding edges). The process of attaching the corner covering is complicated.
Furthermore, in order to use the corner covering disclosed in Patent Document 3, a wall is used to absorb the thickness of the sandwiched portion sandwiched between the two baseboards (or the peripheral edges) and the wall. It is necessary to form a recess in the corner, and the process of attaching the corner covering is complicated.
By the way, the parting material is fixed to the center in the vertical direction of the wall, and in order to cover the gap between the two parting parts attached to the corners of the wall, as in the case of the baseboard or the peripheral edge, It is conceivable to use a corner covering.

  The present invention has been made in view of such circumstances, and its main purpose is to fix the wall fixing member to the wall of the entrance corner or the exit corner, attach the gap covering member to the wall fixing member, By covering the gap between two wall surface construction materials such as wood or surrounding edges, the wall surface construction material and the wall can be easily attached without processing, and the wall construction material is adversely affected by expansion and contraction. An object of the present invention is to provide a corner covering and a corner structure.

  Another object of the present invention is to install in a vertical direction by adopting a configuration in which a protrusion formed on one of the wall fixing member and the gap covering member and a vertically long slit formed on the other are fitted. An object of the present invention is to provide a corner covering that can be easily adjusted in position.

  Another object of the present invention is that the wall fixing member can be more easily provided by having a bent plate-like portion for entering corner and a triangular prism portion along the shape of the wall, and a vertically long hole for entering corner for nailing or screwing. It is to provide a corner covering that can be attached.

  Another object of the present invention is that the wall fixing member can be attached more easily by having a bent plate-like portion for the protruding corner that conforms to the shape of the wall and a vertically long hole for the protruding corner for nailing or screwing. The object is to provide a corner covering that can be used.

  Another object of the present invention is to insert and fix the elastic part between the small edge surfaces of the wall surface construction material by elastic restoring force, and to cover the gap between the two wall surface construction materials such as baseboard, parting material or peripheral edge. To provide a corner covering and a corner structure that can be easily attached without processing the wall surface construction material and the wall, and that are not adversely affected by expansion and contraction of the wall surface construction material. is there.

  Still another object of the present invention is to provide a corner covering that can reduce the material forming the elastic portion by providing the V-shaped elastic portion.

The corner covering device according to the present invention is a corner covering device that covers a gap between two plate-like wall surface construction materials attached to an entrance corner or an exit corner, the covering portion covering the gap, and the wall surface construction. An elastic part that is inserted between the small edge surfaces of the material and fixed by elastic restoring force, the covering part is formed by bending, and the elastic part is a plate that is in contact with one wall surface construction material Jo of which forms a contact piece and the other V-shaped with a plate-shaped contact pieces in contact with the wall fixtures material, any two of the contact pieces directly projecting from the bent portion of the cover portion It is characterized by being.

Corner construction according to the present invention is a corner structure the gap of the two plate-shaped wall fixtures material attached to the inside corner or external corner is a corner cover member covers, small faces of the wall fixtures material Are arranged facing each other, and the corner covering tool is the corner covering tool of the present invention.

In this invention, a coating | coated part and an elastic part are provided integrally. That is, the corner covering tool is composed of one member.
An operator who attaches a corner covering tool to two plate-like wall construction materials (specifically, baseboards, parting materials, or peripheral edges) attached to the entrance corner or the exit corner of the two wall construction materials. An elastic part is inserted between the facets, and the gap between the two wall surface construction materials is covered with the covering part. Such attachment work is simple. In addition, there is no need for adhesion with a double-faced tape to the wall covering material of the corner covering, nailing from the surface of the corner covering.

Since the elastic portion is sandwiched between the small edge surfaces of the two wall surface construction materials by the elastic restoring force, the covering portion integrated with the elastic portion is also fixed to the two wall surface construction materials. That is, the corner covering portion is securely attached to the two wall surface construction materials attached to the entrance corner or the exit corner.
Even if the wall surface construction material expands and contracts, the covering portion that is not directly attached to the wall surface construction material is not damaged by the adverse effects of the external force generated by the expansion and contraction of the wall surface construction material. In addition, the elastic portion sandwiched between the facets does not break due to the adverse effect of the external force by expanding and contracting itself according to the external force.

Moreover , the elastic part is V-shaped, one contact piece of the elastic part is in contact with one of the small edge surfaces of the two wall surface construction materials, and the other contact piece of the elastic portion is the two wall construction materials. The two contact pieces are in contact with the other facet surface and bend and come in contact with each other to function as an elastic body.

In the case of the corner covering tool of the present invention, the elastic portion is inserted between the small edge surfaces of the two plate-like wall surface construction materials, and the gap between the two wall surface construction materials is covered with the coating portion. It can be easily installed without machining the walls.
In addition, since the adhesive with the double-sided tape is unnecessary, the corner covering is difficult to drop off.
Furthermore, since nailing from the surface side of the corner covering device is unnecessary, the aesthetic appearance of the attached corner covering device can be improved.

Further, since the covering portion and the elastic portion are hardly affected by the external force generated by the expansion and contraction of the wall surface construction material, it is possible to suppress the breakage of the corner covering tool due to the applied external force.
In addition, you may adhere | attach a coating | coated part, for example on the edge surface of a wall surface construction material. When the covering portion is adhered, even when an unnecessary external force acts in the direction of pulling out the corner covering tool from between the small edge surfaces of the wall surface construction material, the falling off of the corner covering tool can be suppressed.

Furthermore , since the elastic part has a V shape having two contact pieces, it is more elastic than an elastic part having a shape that almost completely closes between the small edge surfaces of two wall surface construction materials, for example. The material forming the part can be reduced.
In addition, each contact piece can be formed thinner than an elastic part shaped so as to close the gap between the facets, so that it is less elastic than synthetic rubber, such as synthetic resin, but hard. Even if it forms with a simple material, each contact piece can be made flexible. As a result, it is possible to improve the strength of the corner covering device while giving the elastic portion elasticity.

In the case of the corner structure of the present invention, since the corner covering device of the present invention is used, the construction of the corner structure is easy, the aesthetics are improved, and further, the falling off and breakage of the corner covering device are suppressed, The corner structure can have a long life.

The skirting board B1 is made of a plate-like wood member, is arranged along the floor F, is fixed to the wall W1 by nailing, bonding or the like, and the fore edge of the skirting board B1 is separated from the wall W2. Has been placed. Similarly to the skirting board B1, the skirting board B2 is fixed to the wall W2, and the fore end face of the skirting board B2 is arranged so as to face the wall W1.
Decorative grooves D1 and D2 are formed in the lateral direction in front of the baseboards B1 and B2.

  In the figure, 1 is a corner covering tool, and the corner covering tool 1 is composed of two members made of synthetic resin (specifically, a wall fixing member 11 and a gap covering member 12). The corner covering tool 1 covers the gap between the baseboards B1 and B2 in a state where the wall fixing member 11 is fixed to the walls W1 and W2 and the gap covering member 12 is attached to the wall fixing member 11, thereby the baseboard B1. , B2 is covered.

The wall fixing member 11 is manufactured, for example, by injection molding using a synthetic resin. As shown in FIGS. 2, 3 and 5, the triangular prism portion 114 and the bent corner bent plate portion 115 are integrally formed. Yes.
The bent corner bent plate portion 115 is bent in an L shape in plan view along the shape of the walls W1 and W2 at the input corners, and has a protruding portion 111 and a triangular shape in plan view inside the bent portion of the L shape. The four plate-shaped reinforcing portions 113, 113,... Are integrally formed.

  The projecting portion 111 includes projecting pieces 11a and 11b each having an oblong rectangular plate that are spaced apart from each other, and a longitudinal slit 112 is formed between the projecting pieces 11a and 11b. The vertical lengths of the protruding pieces 11a and 11b are substantially equal to the vertical length of the bent corner bent plate portion 115, and a protruding portion 121 to be described later is fitted into the slit 112. The length, that is, the width and depth of the slit 112 is designed to a value necessary for fitting the protrusion 121.

  The reinforcing portions 113, 113,... Are integrally formed by vertically separating the two reinforcing portions 113, 113 between the outer surfaces of the protruding pieces 11 a, 11 b and the front surface of the bent corner plate 115. Thus, unnecessary deformation, damage, etc. of the protruding pieces 11a and 11b are suppressed. As a result, the reinforcing portions 113, 113,... Reinforce the protruding portions 111 that are likely to be deformed, damaged, etc. because the slits 112 are formed.

The triangular prism portion 114 has two side surfaces corresponding to the shapes of the walls W1 and W2 with corners, and one end portion of the triangular prism portion 114 is integrally provided with a bent portion at one longitudinal end portion of the corner bending plate-like portion 115. ing.
The triangular prism portion 114 has an elongated vertical corner hole 116 penetrating from one side surface other than the two side surfaces corresponding to the shape of the walls W1 and W2 at the corners of the triangular column portion 114 to the vertex facing the one side surface. Is formed. A not-shown nail (or screw) is inserted into the longitudinal corner hole 116.

The gap covering member 12 has a size and a shape that can sufficiently cover the wall fixing member 11, and is manufactured by injection molding using, for example, a synthetic resin. As shown in FIGS. The horizontal covering portion 124 and the corner vertical covering portion 125 are integrally formed.
The inner corner horizontal covering portion 124 corresponds to the shape of the upper end surfaces of the two baseboards B1 and B2 attached to the inner corner, and is continuously formed in an L shape.

  The vertical corner covering portion 125 corresponds to the shape of the front of the two baseboards B1 and B2 attached to the corner, and is continuously formed by bending in an L shape. An entrance corner horizontal covering portion 124 is formed at one end of the entrance corner vertical covering portion 125, and a vertically long rectangular plate-like protruding portion 121 is formed outside the bent portion of the entrance corner vertical covering portion 125. Four plate-shaped reinforcing portions 123, 123,... Having a triangular shape in plan view are integrally formed.

  Since the protrusion 121 is fitted in the slit 112, the protrusion 121 is disposed at a portion that should face the protrusion 111 of the wall fixing member 11. Therefore, the vertical length of the protruding portion 121 is substantially equal to the vertical length of the slit 112, and the thickness of the protruding portion 121 is substantially equal to or slightly longer than the width of the slit 112. Further, the protruding portion 121 is formed from the end portion of the vertical corner covering portion 125 on the side opposite to the forming corner horizontal covering portion 124 side to the central portion in the vertical direction.

The reinforcing portions 123, 123,... Are integrally formed with two reinforcing portions 123, 123 spaced apart in the vertical direction between each side surface of the protruding portion 121 and the back surface of the vertical corner covering portion 125. Thus, unnecessary deformation, damage and the like of the protrusion 121 are suppressed.
On the front surface of the vertical corner covering portion 125, a decorative groove 12a corresponding to the decorative grooves D1 and D2 of the baseboards B1 and B2 is formed in the lateral direction. For this reason, on the back surface of the vertical corner covering portion 125, a protruding strip portion 12b that fits into the grooves D1 and D2 is projected. The ridge portion 12b is disposed between the protruding portion 121 and the horizontal covering portion 124 for entering corners.

Next, with reference to FIGS. 1-5, the procedure which attaches the corner covering tool 1 with respect to the two baseboards B1 and B2 attached to the corner is demonstrated.
The worker who installs the corner covering tool 1 first faces the wall fixing member 11 with the corner corner bent plate portion 115 on the lower side and the triangular prism portion 114 on the upper side, and on the corner walls W1 and W2. In addition, the rear surface of the wall fixing member 11, that is, the rear surface of the bent corner bent plate portion 115 (that is, the outer side of the L-shaped bent portion) and the two side surfaces of the triangular prism portion 114 are aligned along the walls W1 and W2. One end (in this case, the lower end) of the bending plate-like portion 115 is brought into contact with the floor F.

  As described above, the wall fixing member 11 can be easily positioned by aligning the bent corner plate 115 for the corner and the triangular prism portion 114 with the walls W1 and W2 and the floor F at the corner. Moreover, since no large gaps are formed between the bent corner plate 115 and the triangular prism portion 114 and the walls W1 and W2 at the corners, the stability of the wall fixing member 11 is improved. At this time, the vertical corner hole 116 is positioned substantially in front of the operator.

  After positioning the wall fixing member 11 as described above, the operator inserts a not-shown nail into the entrance elongated vertical hole 116 of the triangular prism portion 114, and moves the triangular prism portion 114, and thus the wall fixing member 11.

In addition, the wall fixing member 11 has portions that obstruct the operator's hand, tools, etc. on both sides of the longitudinal corner hole 116 (for example, the L-shaped side portions of the corner bending plate-like portion 115). No part). For this reason, the nailing operation is simple.

  Next, the worker places the gap covering member 12 on the upper corner horizontal covering portion 124 on the upper side and the vertical corner covering portion 125 on the lower side, and further sets the protruding portion 121 of the gap covering member 12 on the wall fixing member 11. Is inserted into the slit 112 from above. As a result, the protrusion 121 is fitted into the slit 112, and the gap covering member 12 is fixed to the wall fixing member 11. Further, when the gap covering member 12 is fixed to the wall fixing member 11, the ridges on the back surface of the gap covering member 12 are arranged so that the grooves 12a on the front surface of the gap covering member 12 are aligned with the grooves D1 and D2 of the baseboards B1 and B2. The portion 12b is fitted into the grooves D1 and D2. At this time, the inner corner horizontal covering portion 124 covers the gap between the upper end surfaces of the baseboards B1 and B2, and the inner corner vertical covering portion 125 covers the gap between the front faces of the baseboards B1 and B2. The fixing member 11 is covered with a gap covering member 12.

Since the slit 112 is vertically long, restrictions such as a position and an angle at which the protrusion 121 is fitted into the slit 112 are loose. That is, such attachment work is simple.
Further, since the mounting position in the vertical direction of the gap covering member 12 can be adjusted while fitting the protruding portion 121 into the slit 112, the groove 12a and the grooves D1, D2 are particularly easy to match.

  Since the corner covering tool 1 is hidden by the gap covering member 12, the wall fixing member 11 that is not visible to the user is directly nail-fixed to the walls W1 and W2, and the gap covering member 12 that is visible to the user is provided. Instead of nailing, screwing, or the like, the wall fixing member 11 is fixed to the walls W1 and W2 indirectly by fitting and fixing. For this reason, the corner covering tool 1 improves the aesthetic appearance of the corner covering structure B1 and B2 and / or the wall W1 while reliably covering the gap between the skirting boards B1 and B2, and further improving the aesthetic appearance of the corner structure. , W2 is not required, and the mounting work is simple.

  Further, since the corner covering tool 1 does not require adhesion, nailing, screwing, or the like to the baseboards B1 and B2, even if the baseboards B1 and B2 expand and contract, the wall fixing member 11 of the corner covering tool 1 and Each of the gap covering members 12 does not fall off or be damaged due to the adverse effects of the external force generated by the expansion and contraction of the baseboards B1 and B2.

FIG. 6 is a perspective view showing an appearance of a corner structure in which the corner covering device according to the first embodiment of the present invention covers the gap at the periphery of the entrance corner.
Here, the peripheral edges E1 and E2 which are two wall surface construction materials attached to the corner where two walls W1 and W2 of the room are substantially orthogonal are illustrated. The peripheral edge E1 is made of a plate-like wood member, is arranged along the ceiling C, and is fixed to the wall W1 by nailing, bonding or the like. Similar to the peripheral edge E1, the peripheral edge E2 is fixed to the wall W2. The dimensions, arrangement, etc. of the peripheral edges E1, E2 correspond to the dimensions, arrangement, etc. of the baseboards B1, B2.

In the figure, 1 is a corner covering tool, and the corner covering tool 1 covers the gap between the peripheral edges E1 and E2 in a state where the top and bottom are reversed from the state shown in FIG. That is, the corner covering 1 is shared by the baseboards B1 and B2 and the peripheral edges E1 and E2.
When the corner covering tool 1 is attached to the walls W1 and W2 so as to cover the gap between the peripheral edges E1 and E2, the operator sets the corner bent plate portion 115 on the upper side and the triangular prism portion 114 on the lower side, The wall fixing member 11 is nail-fixed to the walls W1, W2 using the vertically long holes 116.

  Next, the operator places the gap covering member 12 on the lower side with the horizontal covering portion 124 for the entrance corner and the vertical covering portion 125 for the entrance corner on the upper side, and further, the protrusion 121 of the gap covering member 12 with the wall fixing member 11. Is inserted into the slit 112 from below. As a result, the protrusion 121 is fitted into the slit 112, and the gap covering member 12 is fixed to the wall fixing member 11.

  The corner covering tool 1 of the present embodiment covers the gap between the parting materials, which are two wall surface construction materials attached to the corners, in the same manner as when the gap between the baseboards B1 and B2 is covered. Is possible. However, this parting material is arranged at a position lower than the user's line of sight. When covering the gap between the two parting materials arranged higher than the user's line of sight, the corner covering tool 1 is attached to the walls W1 and W2 in the same manner as when covering the gap between the peripheral edges E1 and E2. It is done.

Are integrally formed by vertically separating two reinforcing portions 223, 223 between each side surface of the projecting portion 221 and the back surface of the vertical covering vertical portion 225. As a result, unnecessary deformation, damage, and the like of the protruding portion 221 are suppressed.
On the front surface of the vertical corner covering portion 225, decorative grooves 22a corresponding to the decorative grooves D3 and D4 of the baseboards B3 and B4 are formed in the lateral direction. For this reason, on the back surface of the vertical covering portion 225 for protruding corners, a protruding strip portion 22b that fits into the grooves D3 and D4 is projected. The protruding portion 22b is disposed between the protruding portion 221 and the horizontal covering portion 224 for the projected corner.

Next, with reference to FIGS. 7-11, the procedure which attaches the corner covering tool 2 with respect to the two baseboards B3 and B4 attached to the exit corner is demonstrated.
An operator who installs the corner covering tool 2 first faces the wall fixing member 21 with the slit 212 forming side on the lower side and the protruding corner vertical hole 216 forming side on the upper side with the protruding corner walls W3 and W4, Next, the rear surface of the wall fixing member 21, that is, the rear surface of the bent corner bent plate portion 214 (that is, the inner side of the bent portion of the L shape) is placed along the walls W 3 and W 4, and One direction end (in this case, the lower end) is brought into contact with the floor F.

Thus, by positioning the bent corner bent plate portion 214 to the walls W3, W4 and the floor F of the protruding corner, the positioning of the wall fixing member 21 is facilitated. In addition, since a large gap does not occur between the bent corner bending plate portion 214 and the protruding corner walls W3, W4, the stability of the wall fixing member 21 is improved. At this time, the vertical corner hole 216 is positioned substantially in front of the operator.
After positioning the wall fixing member 21 as described above, the operator inserts a not-shown nail into the protruding corner longitudinal hole 216 to nail and fix the wall fixing member 21 to the walls W3 and W4. Here, the vertical hole 216 for the corners is loosely restricted in the position and angle in the vertical direction where the nail is inserted. For this reason, the nailing operation is simple.

  Next, the operator places the gap covering member 22 on the upper corner with the horizontal covering portion 224 for the protruding corner and the vertical covering portion 225 for the protruding corner on the lower side, and further sets the protruding portion 221 of the gap covering member 22 with the wall fixing member 21.

The portion 22b is fitted into the grooves D3 and D4. At this time, the protruding corner horizontal covering portion 224 covers the gap between the upper end surfaces of the baseboards B3 and B4, and the protruding corner vertical covering portion 225 covers the gap between the front faces of the baseboards B3 and B4. The fixing member 21 is covered with the gap covering member 22.

Since the slit 212 is vertically long, restrictions such as a position and an angle at which the protrusion 221 is fitted into the slit 212 are loose. That is, such attachment work is simple.
In addition, since the mounting position in the vertical direction of the gap covering member 22 can be adjusted while fitting the protruding portion 221 into the slit 212, the groove 22a and the grooves D3 and D4 are particularly easy to match.
Other parts corresponding to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  Since the corner covering tool 2 as described above is hidden by the gap covering member 22, the wall fixing member 21 that cannot be seen by the user is directly nailed and fixed to the walls W3 and W4. It is fixed to the walls W3 and W4 indirectly by fitting and fixing to the wall fixing member 21, regardless of nailing, screwing or the like. For this reason, the corner covering tool 2 improves the aesthetic appearance of the corner structure B3, B4 and / or the wall W3 while reliably covering the gap between the skirting boards B3, B4, and further improving the aesthetic appearance of the corner structure. , W4 is not required, and the mounting operation is simple.

  Further, since the corner covering tool 2 does not require adhesion, nailing, screwing or the like to the baseboards B3 and B4, even if the baseboards B3 and B4 expand and contract, the wall fixing member 21 of the corner covering tool 2 and Each of the gap covering members 22 is not dropped or damaged due to an adverse effect of the external force generated by the expansion and contraction of the baseboards B3 and B4.

Similar to the peripheral edge E3, the peripheral edge E4 is fixed to the wall W4. The dimensions and arrangement of the peripheral edges E3 and E4 correspond to the dimensions and arrangement of the baseboards B3 and B4.

In the figure, 2 is a corner covering tool, and the corner covering tool 2 covers the gap between the peripheral edges E3 and E4 in a state where the top and bottom are reversed from the state shown in FIG. That is, the corner covering 2 is shared by the baseboards B3 and B4 and the peripheral edges E3 and E4.
When the corner covering tool 2 is attached to the walls W3 and W4 so as to cover the gap between the peripheral edges E3 and E4, the operator places the slit 212 forming side on the upper side and the outgoing corner vertically long hole 216 forming side on the lower side. The wall fixing member 21 is nail-fixed to the walls W3, W4 using the vertical holes 216 for use.

  Next, the operator places the gap covering member 22 on the lower side with the horizontal covering portion 224 for the protruding corner and the vertical covering portion 225 for the protruding corner on the upper side, and further sets the protruding portion 221 of the gap covering member 22 on the wall fixing member 21. Is inserted into the slit 212 from below. As a result, the protrusion 221 is fitted into the slit 212, and the gap covering member 22 is fixed to the wall fixing member 21.

  Note that the corner covering tool 2 of the present embodiment can cover the gap between the two parting materials attached to the exit corner in the same manner as the case where the gap between the baseboards B3 and B4 is covered. is there. However, this parting material is arranged at a position lower than the user's line of sight. When covering the gap between the two parting members arranged higher than the user's line of sight, the corner covering tool 2 is attached to the walls W3 and W4 in the same manner as when covering the gap between the peripheral edges E3 and E4. It is done.
