Description

The present invention provides a pair of baseboards or a surrounding edge of a board material, which has grooves formed along the longitudinal direction of the surface and is placed on both sides of the wall surface near the floor or ceiling so that the back surface is aligned with the wall surface. The present invention relates to a plate cover that covers both abutting portions.

In a building, a baseboard is provided on the wall near the floor surface, and a circumferential edge is provided on the wall near the ceiling. Board materials such as baseboards or surrounding edges improve the appearance of the wall surface and protect the wall surface. Since this plate material is formed in a straight line, abutting portions of a pair of plate materials abutted against each other at wall surfaces such as an external corner and an internal corner create a gap between the abutting surfaces (butt ends). The plate material cover covers the abutting portions of both of the above-mentioned pair of plate materials and hides the above-mentioned gap.

The board cover described in Patent Document 1 has a surface covering part that covers the board material and a surface covering part that extends to the back side of the surface covering part by arranging the tip parts facing each other on the ceiling or the floor, so that the back surface of the board material and the wall surface are connected to each other. By placing it between the plate-shaped blades that sandwich the plate material together with the surface covering part, and the plate-shaped blade part that extends along the vertical direction so as to partition the abutting end surfaces of both of the pair of plate materials, and is joined to the blade part. A blade support part that supports the blade part. Further, the surface covering part is formed with an engaging convex part that engages with the groove formed in the longitudinal direction of the surface of the plate material, and the joint part between the blade part and the blade support part is engaged in the vertical direction. It is arranged so that it is located closer to the tip than the convex portion. As a result, when the plate material cover is attached to the abutting portions of both of the pair of plate materials, the plate material is held between the surface covering part and the blade part, so the horizontal movement of the plate material cover can be restrained. Furthermore, since the concave groove formed on the surface of the plate material engages with the engagement convex portion formed on the surface covering portion, movement of the plate material cover in the vertical direction can be restrained. Therefore, it is possible to prevent the plate cover from falling off from the plate without using double-sided tape or adhesive to fix the plate cover to the plate.

Furthermore, in the plate material cover described in Patent Document 1, the joint portion between the blade portion and the blade support portion that supports the blade portion is located closer to the tip portion than the engagement projection portion in the vertical direction, and the engagement portion There is no joint part of the blade part joined to the blade support part at the position facing the blade support part. As a result, when the plate material cover is attached to the plate material from the vertical direction, even if the engagement convex portion formed on the surface covering part rides on the surface of the plate material before it engages with the groove of the plate material, the engagement will not occur. Since there are no blades in positions facing the protrusions, there is no damage to the surface coating or blades due to excessive force, and the board cover can be smoothly placed at the corner of the wall.

Patent No. 5391128

However, in the plate material cover described in Patent Document 1, when attached to the abutting portions of both of the pair of plate materials, the portion of the surface covering portion closer to the proximal end than the portion where the engagement convex portion is formed There are no blades on the back side that hold the plate material. That is, the range from the base end of the surface covering portion of the plate material cover to at least the engagement convex portion only covers the surface of the plate material and does not sandwich the plate material.

Therefore, when the plate material cover is kicked by a foot or hit by a vacuum cleaner, etc., the range from the base end of the surface covering part to the engaging convex part is easily flipped over from the surface of the plate material, and a pair of There is a risk that it may fall off from the abutting portions of both plates.

It is attached and attached to the plate material. Therefore, even if the board cover is kicked by a foot or hit by a vacuum cleaner, etc., the board cover is attached so as to wrap around the board, and will remain stable on the board without peeling off. be done.

According to i and ii described above, it is possible to stably prevent the plate material cover from falling off from the plate material without using double-sided tape or adhesive for fixing the plate material cover to the plate material.

(Claim 2)
(c) When the plate material cover is attached to the abutting portion of a pair of plate materials, the surface covering portion is attached to the plate material in a state in which the engaging convex portion of the surface covering portion is engaged with the groove formed on the surface of the plate material. A back plate part that covers the surface of the surface covering part and extends from the base end of the surface covering part to the back side of the surface covering part is inserted between the back surface of the board material and the wall surface and covers the board material together with the surface covering part. The clamping portion, and furthermore, the portion of the surface covering portion that does not completely overlap with the engaging convex portion is connected to the back plate portion by the connecting portion.

(d)i. According to (c) above, the plate material cover is restrained from moving in the horizontal direction by sandwiching the plate material between the surface covering part and the back plate part, and the grooves formed on the surface of the plate material and the surface Movement in the vertical direction is restrained by engagement with the engagement convex portion formed on the covering portion.

ii. According to (c) above, the plate material cover is configured to hold the proximal end of the surface covering part in a state in which the engagement protrusion formed between the base end and the distal end of the surface covering part is engaged with the groove of the plate material.

In such a configuration, when the plate cover is attached, elastic deformation in the direction in which the surface covering part and the back plate part are separated is not excessively hindered by the connecting part. Thereby, the ease of attaching the plate cover can be further improved.

(Claim 3)
(e) A portion of the surface covering portion located closer to the tip than the engaging convex portion is connected to the back plate portion by the connecting portion.

According to (e) above, the plate material cover is configured to hold the proximal end of the surface covering part with the engagement protrusion formed between the proximal end and the distal end of the surface covering part engaged with the groove of the plate material. A back plate portion joined to the surface covering portion and extending to the back side of the surface covering portion is connected to a portion of the surface covering portion located closer to the tip portion than the engaging convex portion via a connecting portion. Ru. That is, in the plate material cover, the surface covering part, the proximal end of the surface covering part, the back plate part, and the connecting part are in a state where the surface covering part engages the engagement convex part with the groove on the surface of the plate material. An endless circumferential portion connected in a closed cross-sectional shape is attached to the plate material so as to wrap around a portion of the plate material extending from the front surface to the back surface including the groove. Therefore, even if the board cover is kicked by a foot or hit by a vacuum cleaner, etc., the board cover is attached so as to wrap around the concave groove of the board, and it can be stably covered without being turned over from the board. It is attached to the plate material.

According to the above (e), it is possible to stably prevent the plate material cover from falling off from the plate material without using double-sided tape or adhesive for fixing the plate material cover to the plate material.

(f) The plate material cover connects the surface covering portion and the back plate portion by a connecting portion provided at a portion of the surface covering portion located closer to the tip than the engagement convex portion. Therefore, compared to a connecting part provided at a portion of the surface covering part where the engaging protrusion is located, the elasticity of the surface covering part tends to separate the engaging protrusion from the back plate side. It does not actively prevent natural deformation. That is, in the process of attaching the plate material cover to the plate material from the vertical direction, when the engagement protrusion formed on the surface covering part rides on the surface of the plate material before engaging with the groove of the plate material, the engagement protrusion Since there is no connecting part at a position opposite to the part, the surrounding part of the engaging convex part in the surface covering part elastically bulges and deforms, easily separating the engaging convex part from the side of the back plate part. The engagement convex portion can be smoothly engaged with the concave groove by being displaced so as to be displaced and then immediately elastically restored. That is, the peripheral portion of the engagement protrusion in the surface covering portion will not be damaged due to excessive force during the above-mentioned installation, and the plate cover can be easily attached to the abutting portion of the pair of plates.

(Claim 4)
(g) By connecting the back plate portion to the tip of the surface covering portion, the connecting portion prevents the deformation described in (f) above from being exerted by the connecting portion on the peripheral portion of the engagement protrusion in the surface covering portion.

It has become a target. In the invention according to claim 6, the connecting portion connects a portion of the surface covering portion located closer to the proximal end than the engaging convex portion and the back plate portion. Since the portion to which the impact of the hammer is applied is reinforced by the presence of the connecting portion, damage to the portion is prevented. For example, if it is necessary to adjust the length of the board cover at a construction site, cut off the part of the surface covering part or backboard part on the tip side, that is, the part where the connecting part is not formed. You can adjust the length by

(Claim 7)
(j) The end of the connecting portion closest to the distal end is located at the same position as the boundary between the bottom and the side wall, or at a position closer to the proximal end than the boundary. Since the elastic deformation of the plate cover that occurs when the engagement protrusion fits into the groove is less likely to be hindered by the connecting portion, the plate cover can be attached more easily than before.

(Claim 8)
(k) The end of the connecting part that is closest to the distal end is located at the same position as the end of the side wall that is closest to the proximal end, or at a position that is closer to the proximal end than that position. ing. That is, the connecting portion is formed along the direction from the distal end side to the proximal end side at a position that does not overlap the engaging convex portion at all. In such a configuration, the deformation of the plate cover that occurs when the engaging convex part fits into the groove is less likely to be impeded by the connecting part, so the plate cover can be attached more easily than before. becomes.

(Claim 9)
(l) The end of the surface covering portion closest to the tip extends so as to protrude further beyond the end of the back plate portion closest to the tip. In such a configuration, when attaching the plate cover, first, only the vicinity of the tip of the surface covering portion is brought into contact with the surfaces of the pair of plate materials, and the plate cover can be slid along the surfaces. When the plate material cover is slid in this manner, the tip of the back plate portion is smoothly guided toward the space between the plate material and the wall surface. Therefore, the plate cover can be attached more easily than when the front end position of the surface covering part and the front end position of the back plate part are aligned.

(Claim 10)
(m) The back plate portion is provided with a hooking portion to the wall surface in a pulling direction opposite to the insertion direction into the wall surface, so that the back plate portion is inserted between the back surface of the plate material and the wall surface and attached to the plate material. The ability to prevent the attached plate cover from falling off the plate can be further improved.

(Claim 11)
(n) Since the tip portion of the back plate portion has a tapered shape, it is possible to improve the insertability of the back plate portion between the back surface of the plate material and the wall surface.

This embodiment will be described below with reference to the accompanying drawings. In order to facilitate understanding of the description, the same components in each drawing are denoted by the same reference numerals as much as possible, and redundant description will be omitted.

The protruding corner plate material cover 10 according to the first embodiment shown in FIGS. 1 and 2 has an abutting portion of both of a pair of plate materials 1, 1 disposed at the protruding corner WA of the wall surface W shown in FIGS. 5 and 6. Cover 2. Note that the abutting end surfaces (butt ends) of each plate material 1 face each other to form a certain gap G (FIG. 6).

In FIGS. 5 and 6, a pair of boards 1, 1 to which the protruding corner board cover 10 is applied constitute a pair of baseboards arranged on both sides of a wall W near the floor. However, the pair of plates 1, 1 to which this protruding corner plate cover 10 is applied may constitute a pair of surrounding edges (not shown) disposed on both sides of the wall W near the ceiling. Here, each plate material 1 is arranged such that a groove 1K (FIG. 5) is formed along the longitudinal direction of the front surface 1A, and the back surface 1B is aligned with the wall surface W.

The protruding corner plate cover 10 is made of resin integrally molded by injection molding, and has a surface covering portion 11, an engaging convex portion 12, a back plate portion 13, and a connecting portion 14.

The surface covering portion 11 has an L-shaped cross section along the horizontal direction in accordance with the shape of the protruding corner WA of the wall surface W, and has a height approximately the same as the height H (FIG. 5) of the pair of plate materials 1, 1. The pair of plate materials 1 are provided with a height of 100 mm and extend along the height direction from the base end 11A to the distal end 11B, and by arranging the distal end 11B facing the floor (or ceiling). , 1 are coated. Note that the base end portion 11A of the surface covering portion 11 constitutes a portion that covers the upper end surface 1C of each plate material 1.

The engaging convex portion 12 extends across the entire L-shaped cross section along the horizontal direction between the base end 11A and the distal end 11B of the surface covering portion 11, in this embodiment, the intermediate portion in the height direction. It is formed to protrude from the top toward the back surface and engages with the grooves 1K of both of the pair of plates 1, 1.

The back plate part 13 extends along the back side of the surface covering part 11 from the base end side joined to the base end part 11A of the surface covering part 11 toward the distal end side, and includes the pair of plate members 1, 1, and is inserted vertically from the tip side between the back surface 1B of both abutting portions 2 of the pair of plates 1, 1 and the wall surface W, and covers both the abutting portions 2 of the pair of plate materials 1, 1 together with the surface covering portion 11. to hold. In addition, like the surface covering part 11, the back plate part 13 has an L-shaped cross section along the horizontal direction in accordance with the shape of the protruding corner WA of the wall surface W, and has left and right sides sandwiching the center line 13H of the L-shaped cross section. It consists of back plates 13A and 13B, and has a height that is approximately the same as the height H of the pair of plate members 1, 1.

The connecting portion 14 is arranged within the gap G so as to have approximately the same length in the horizontal direction in the gap G formed by the abutting portions 2 of the pair of plate materials 1, 1, and is arranged within the gap G. A portion located closer to the tip portion 11B than the engagement convex portion 12 in the longitudinal direction (in the present embodiment, the tip L-shaped corner portion 11V of the surface covering portion 11) and the back plate portion 13 (in the present embodiment, the back plate portion 13 and the L-shaped corner portion 13V) at the tip. In this embodiment, along the direction from the distal end portion 11B side to the base end portion 11A side, that is, along the vertical direction, the range of the portion of the surface covering portion 11 connected by the connecting portion 14 is the engagement convex. This range does not overlap with part 12 at all.

That is, in this embodiment, the connecting portion 14 connects the back plate portion 13 to the tip portion 11B of the surface covering portion 11. At this time, the back plate portion 13 is joined to the base end portion 11A of the surface covering portion 11, and extends to the lower end portions of the plate members 1, 1 in the height direction.

Further, in this embodiment, as shown in FIGS. 1 and 2, the connecting portion 14 has a rod shape in which the cross section perpendicular to the direction from the surface covering portion 11 to the back plate portion 13 is a square rod or a round rod. It is said that

As a result, when attaching the protruding corner plate cover 10 to the abutting portion 2 of the pair of plate materials 1, 1, the back plate portion 13 is connected to the back surface 1B of both the plate materials 1, 1 and the wall surface W, as shown in FIG. When the engaging convex portion 12 formed on the surface covering portion 11 rides on the surface 1A of the plate material 1 before it engages with the groove 1K of each plate material 1, There is no connecting part 14 in the area facing the engagement protrusion 12, and the peripheral part of the engagement protrusion 12 in the surface covering part 11 elastically expands and deforms, so that the engagement protrusion 12 is smoothly recessed. This allows it to fit into the groove 1K.

Therefore, according to the protruding corner plate material cover 10 of this embodiment, the following effects are achieved.

(a) When the protruding corner plate cover 10 is attached to the abutting portion 2 of the pair of plate materials 1, 1, the surface covering portion 11 covers the surface 1A of the plate material 1, and the surface covering portion 11 covers the surface 1A of the plate material 1, and extends from the base end 11A of the surface covering portion 11. A back plate part 13 extending to the back side of the surface covering part 11 is inserted between the back surface 1B of the plate material 1 and the wall surface W to sandwich the plate material 1 together with the surface covering part 11.

The ability to prevent the plate material 1 from falling off when the plate material 1 is attached to the plate material 1 can be further improved.

The connecting portion may connect the back plate portion and the intermediate portion located between the engagement convex portion and the tip portion of the surface covering portion, as shown by the two-dot chain line in FIG. 7(A). At this time, the back plate portion does not need to extend to the lower end portion in the height direction of the plate material as long as it is joined to the base end portion of the surface covering portion.

Further, the plate material cover may have a plurality of connecting portions arranged in gaps between abutting portions of both of the pair of plate materials.

A fourth embodiment will be described. The protruding corner plate material cover 100 according to the present embodiment covers the abutting portions 2 of both the plate materials 1, 1 arranged at the protruding corner WA in FIG. 5, similarly to the protruding corner plate material cover 10 according to the first embodiment. It is something. The configuration of the protruding corner board cover 100 will be described with reference to FIGS. 39 and 40. The protruding corner board cover 100 includes a surface covering portion 110, a back plate portion 130, and a connecting portion 140.

The surface covering part 110 is a part that covers the surfaces 1A (see FIG. 5) of the abutting parts 2 of both the pair of plate materials 1, 1, like the surface covering part 11 in the first embodiment. The surface covering section 110 has a first covering section 111 and a second covering section 112. The first covering part 111 is a part that covers the surface 1A of one of the pair of board materials 1 shown in FIG. 5, and the second covering part 112 covers the surface 1A of the other board material 1. It is a part. The first covering part 111 and the second covering part 112 are arranged such that their normal directions are perpendicular to each other.

As in the first embodiment, one end of the surface covering portion 110 is a proximal end 110A, and the other end is a distal end 110B. When the pair of boards 1, 1 to which the protruding corner board cover 100 is attached is a circumferential edge provided near the ceiling, "one end" where the base end 110A is located refers to The "other end" where the distal end portion 110B is located is the upper end along the vertical direction.

In addition, when the pair of boards 1, 1 to which the protruding corner board cover 100 is attached are baseboards installed near the floor, "one end" with the base end 110A refers to the upper and lower ends. This means the upper end along the direction, and the "other end" where the tip portion 110B is located means the lower end along the up-down direction.

In either case, when the protruding corner plate material cover 100 is attached to the pair of plate materials 1, 1, the direction from the distal end portion 110B side to the base end portion 110A side is the direction along the up-down direction. Become. Therefore, in the following description, the term "vertical direction" may be used to indicate the "direction from the distal end portion 110B side to the proximal end portion 110A side."

Similar to the base end portion 11A in the first embodiment, the base end portion 110A of the surface covering portion 110 extends toward the wall surface W, and a back plate portion 130, which will be described later, is connected to its tip.

An engaging convex portion 120 is formed on the surface covering portion 110 . Like the engaging protrusion 12 in the first embodiment, the engaging protrusion 120 extends toward the back plate part 130 so as to engage with the groove 1K (see FIG. 5) of the pair of plate materials 1, 1. This is the part that stands out. The direction in which the engaging convex portion 120 extends is the direction along the horizontal plane when the protruding corner plate material cover 100 is attached to the pair of plate materials 1, 1. The engaging convex portion 120 is formed to extend over both the first covering portion 111 and the second covering portion 112 at a height position between the base end portion 110A and the distal end portion 110B.

Like the back plate part 13 in the first embodiment, the back plate part 130 is inserted between the back surface 1B and the wall surface W of both the plate materials 1, 1 (see FIG. 5), and is inserted into the plate material together with the surface covering part 110. This is the part that sandwiches 1 and 1 from both sides.

The back plate portion 130 includes a first back plate portion 131 and a second back plate portion 132. The first back plate portion 131 is a portion that covers the back surface 1B of one of the pair of plate materials 1 shown in FIG. be. The second back plate portion 132 is a portion that covers the back surface 1B of the other plate material 1, and is a portion that faces the second covering portion 112 of the surface covering portion 110. The first back plate portion 131 and the second back plate portion 132 are arranged such that their normal directions are perpendicular to each other.

The end portion of the back plate portion 130 on the base end portion 110A side (the upper end portion in FIG. 39) is also referred to as “end portion 130A” below. The end portion 130A is connected to the base end portion 110A of the surface covering portion 110. The end of the back plate portion 130 on the distal end portion 110B side (the lower end in FIG. 39) is hereinafter also referred to as "end portion 130B."

As shown in FIG. 39(B), the length of the surface covering portion 110 along the direction from the distal end portion 110B side to the proximal end portion 110A side (that is, the up-down direction) is equal to the length of the surface covering portion 110 along the direction It is longer than the length of section 130. Therefore, the position of the end portion 130B along the vertical direction is between the base end portion 110A and the distal end portion 110B.

The connecting portion 140 is a portion provided to connect the surface covering portion 110 and the back plate portion 130, similar to the connecting portion 14 in the first embodiment. As shown in FIG. 40(B), FIG. 40(C), and FIG. 40(F), the connecting portion 140 of this embodiment is formed into a plate shape. Further, as shown in FIG. 40(F), a part of the connecting part 140 is connected to a corner part of the surface covering part 110 that is the boundary between the first covering part 111 and the second covering part 112. . Further, another part of the connecting portion 140 is connected to a corner portion of the back plate portion 130 that is a boundary between the first back plate portion 131 and the second back plate portion 132. That is, the connecting portion 140 is provided between the surface covering portion 110 and the back plate portion 130 so as to connect the respective corner portions.

The position of the connecting portion 140 in the vertical direction will be explained with reference to FIG. 41. FIG. 41 schematically shows a state in which the protruding corner plate cover 100 is cut along a plane parallel to the connecting portion 140. As shown in the figure, the engaging convex portion 120 has a bottom portion 122, a side wall portion 121, and a side wall portion 123.

The bottom portion 122 is the portion that is most retracted toward the back plate portion 130 and is parallel to the back plate portion 130. A dotted line DL2 shown in FIG. 41 indicates the position of the end of the bottom portion 122 closest to the base end portion 110A. Further, a dotted line DL3 shown in FIG. 41 indicates the position of the end of the bottom portion 122 that is closest to the tip portion 110B.

The side wall portion 121 is a portion that is connected to the bottom portion 122 from the base end portion 110A side, and is a portion that is inclined with respect to the back plate portion 130. A dotted line DL1 shown in FIG. 41 indicates the position of the end of the side wall portion 121 that is closest to the base end portion 110A. Further, the position indicated by the dotted line DL2 described above can also be said to be the position of the end of the side wall portion 121 closest to the tip portion 110B, that is, the position of the boundary between the bottom portion 122 and the side wall portion 121.

The side wall portion 123 is a portion that is connected to the bottom portion 122 from the tip portion 110B side, and is a portion that is inclined with respect to the back plate portion 130. A dotted line DL4 shown in FIG. 41 indicates the position of the end of the side wall portion 123 that is closest to the distal end portion 110B side. Further, the position indicated by the dotted line DL3 described above can also be said to be the position of the end of the side wall portion 123 closest to the base end portion 110A, that is, the position of the boundary between the bottom portion 122 and the side wall portion 123.

As shown in FIG. 41, the end of the connecting portion 140 closest to the proximal end 110A is connected to the proximal end 110A from the inside. Therefore, the connecting part 140 is provided to connect three parts, which are the part of the surface covering part 110 that faces the back plate part 130, the base end part 110A of the surface covering part 110, and the back plate part 130. It is being

The end portion 141 of the connecting portion 140 closest to the distal end portion 11B (lower side in FIG. 41) has a side wall portion along the direction from the distal end portion 110B side to the proximal end portion 110A side (that is, the vertical direction). 121, it is arranged at the same position as the end closest to the proximal end 110A, that is, at the position indicated by the dotted line DL1 in FIG. In other words, the connecting portion 140 of this embodiment connects a portion of the surface covering portion 110 located closer to the base end portion 110A than the engaging convex portion 120 to the back plate portion 130.

The effects of such a configuration will be explained. FIG. 42 schematically shows how the protruding corner plate cover 100 is elastically deformed during the work of attaching the protruding corner plate cover 100 to the plate 1. As shown in the figure, after the protruding corner plate cover 100 is slid downward and the engaging convex portion 120 begins to climb over the upper end of the plate 1, the protruding corner plate cover 100 has the following: A force is applied to force the space between the surface covering portion 110 and the back plate portion 130 to expand.

If the connecting portion 140 is connected to the entire engagement convex portion 120, that is, if the connecting portion 140 is connected to the entire engagement convex portion 120, the connecting portion 140 is connected so that the end portion 141 is located closer to the tip portion 110B than the dotted line DL4 in FIG. If so, elastic deformation of the protruding corner board cover 100 as shown in FIG. 42 is less likely to occur. As a result, the engagement convex portion 120 becomes difficult to get over the upper end of the plate material 1 and fit into the groove 1K, so that the workability of the protruding corner plate material cover 100 deteriorates.

In contrast, in the present embodiment, the connecting portion 140 is provided in a portion of the surface covering portion 110 that is located closer to the proximal end portion 110A than the engaging convex portion 120, so that at least the engaging convex portion 120 Elastic deformation as shown in FIG. 42 is not excessively hindered in the portion. Since the workability of the projecting corner board cover 100 does not deteriorate as described above, the ease of attaching the projecting corner board cover 100 can be improved.

In addition, if the connecting part 140 is not provided in the protruding corner board cover 100, elastic deformation that causes the surface covering part 110 and the back plate part 130 to separate from each other is more likely to occur. The workability of the plate cover 100 will not deteriorate. However, in this case, even after the protruding corner plate material cover 100 is attached to the plate material 1, the above elastic deformation is likely to occur. For this reason, there is a high possibility that the front end portion 110B side of the surface covering portion 110 will flutter away from the surface 1A of the plate material 1.

On the other hand, in this embodiment, the surface covering part 110 and the back plate part 130 are connected by the connecting part 140, and elastic deformation that would cause them to separate is appropriately suppressed. Therefore, while ensuring the workability of the protruding corner board cover 100, it is possible to prevent the front end portion 110B side of the surface covering portion 110 from flapping after the work is completed.

A specific embodiment of the configuration in which “the connecting portion 140 is provided in a portion of the surface covering portion 110 that is located closer to the proximal end portion 110A than the engaging convex portion 120” is shown in FIG. The present invention is not limited to the aspects of this embodiment. For example, the position of the end portion 141 of the connecting portion 140 may be closer to the proximal end portion 110A than the dotted line DL1 in FIG. It is also possible to adopt an embodiment in which That is, along the direction from the distal end portion 110B side to the proximal end portion 110A side (that is, the vertical direction), the range of the portion of the surface covering portion 110 that is connected by the connecting portion 140 is It suffices as long as it does not completely overlap.

In other words, the end portion 141 of the connecting portion 140 closest to the distal end portion 110B is at the same position as the boundary between the bottom portion 122 and the side wall portion 121 (dotted line DL2 in FIG. 41), or at the same position along the vertical direction. It suffices if it is placed at a position closer to the proximal end portion 110A than the base end portion 110A. However, from the viewpoint of making it easier to cause the elastic deformation shown in FIG. The dotted line DL1) or a position closer to the proximal end 110A than the position is preferable. That is, it is preferable that the connecting portion 140 is formed at a position that does not overlap the engaging convex portion 120 at all along the vertical direction. Furthermore, from the viewpoint of appropriately suppressing elastic deformation such as separation between the surface covering part 110 and the back plate part 130, as in this embodiment, the end part 141 is located at the position indicated by the dotted line DL1 in FIG. It is preferable that the

FIG. 43 schematically shows how the projecting corner board cover 100 is being attached to the board 1. As shown in the figure, when attaching the protruding corner board cover 100 to the board 1, for example, a piece of wood 202 is brought into contact with the end of the protruding corner board cover 100 on the base end 110A side. Then, the work of hammering the protruding corner board cover 100 through the wood 202 with the hammer 201 is performed. Since a strong impact from the hammer 201 is applied to the proximal end portion 110A and its vicinity of the protruding corner plate cover 100, there is a concern that this portion may be damaged. However, in the protruding corner plate material cover 100 according to the present embodiment, the connecting portion 140 is located between the portion of the surface covering portion 110 located closer to the base end portion 110A than the engagement convex portion 120 and the back plate portion 130. are connected. Since the portion of the hammer 201 to which the impact is applied is reinforced by the presence of the connecting portion 140, this embodiment prevents this portion from being damaged. In this manner, the configuration of this embodiment also provides the effect of preventing damage to the protruding corner plate cover 100.

By the way, at a construction site where the work shown in FIG. 43 is performed, the dimension of the board 1 along the vertical direction is shorter than the dimension of the projecting corner board cover 100 in the same direction, and the projecting corner board cover It may be necessary to adjust the length of 100. In this embodiment, the connecting portion 140 is not provided in a portion closer to the tip portion 110B than the engaging convex portion 120. Therefore, when it becomes necessary to adjust the length of the protruding corner board cover 100 as described above, for example, the length can be easily adjusted by cutting the portion of the surface covering portion 110 on the tip portion 110B side. It is possible to do so.

As described above with reference to FIG. 39(B), the length of the surface covering portion 110 along the direction from the distal end portion 110B side to the proximal end portion 110A side (that is, the up-down direction) is The length of the back plate portion 130 is longer than the length of the back plate portion 130 along the . In other words, the distal end portion 110B of the surface covering portion 110 that is the most distal end extends further beyond the distal end portion 130B of the back plate portion 130.

In such a configuration, when attaching the protruding corner plate material cover 100 to the plate material 1, as shown in FIG. The projecting corner plate material cover 100 can be brought into contact with the surface 1A and slid along the surface 1A. When the protruding corner board cover 100 is slid in this manner, the end portion 130B of the back plate portion 130 is smoothly guided toward the space between the board 1 and the wall surface W. Therefore, in this embodiment, the protruding corner board cover 100 can be attached more easily than when the tip position of the surface covering part 110 and the tip position of the back plate part 130 are aligned. .

A fifth embodiment will be described. The corner board cover 200 according to the present embodiment covers the abutting portions 2 of both the boards 1, 1 arranged at the corner WB in FIG. 5, similarly to the corner board cover 20 according to the second embodiment. It is something. The corner board cover 200 has the same configuration as the connecting portion 140 in the fourth embodiment applied to the board cover at the corner.

The configuration of the corner board cover 200 will be described with reference to FIGS. 45 and 46. The corner board cover 200 includes a surface covering portion 210, a back plate portion 230, and a connecting portion 240.

The surface covering part 210 is a part that covers the surfaces 1A (see FIG. 5) of the abutting parts 2 of both the pair of plate materials 1, 1, like the surface covering part 110 in the fourth embodiment. The surface covering section 210 has a first covering section 211 and a second covering section 212. The first covering part 211 is a part that covers the surface 1A of one of the pair of board materials 1 shown in FIG. 5, and the second covering part 212 covers the surface 1A of the other board material 1. It is a part. The first covering part 211 and the second covering part 212 are arranged such that their normal directions are perpendicular to each other.

Similar to the fourth embodiment, one end of the surface covering portion 210 is a proximal end 210A, and the other end is a distal end 210B. When the pair of boards 1, 1 to which the corner board cover 200 is attached is a circumferential edge provided near the ceiling, the "one end" where the base end 210A is located refers to The "other end" of the tip 210B is the upper end along the vertical direction.

In addition, when the pair of boards 1, 1 to which the corner board cover 200 is attached are baseboards installed near the floor, "one end" with the base end 210A refers to the upper and lower ends. This means the upper end along the direction, and the "other end" where the tip portion 210B is located means the lower end along the up-down direction.

In either case, when the corner board cover 200 is attached to the pair of boards 1, 1, the direction from the distal end 210B side to the base end 210A side is the direction along the up-down direction. Become. Therefore, in the following description, the term "vertical direction" may be used to indicate the "direction from the distal end portion 210B side to the proximal end portion 210A side."

Similar to the base end portion 110A in the fourth embodiment, the base end portion 210A of the surface covering portion 210 extends toward the wall surface W, and a back plate portion 230, which will be described later, is connected to its tip.

An engaging convex portion 220 is formed on the surface covering portion 210 . Similar to the engagement protrusion 120 in the fourth embodiment, the engagement protrusion 220 extends toward the back plate part 230 so as to engage with the groove 1K (see FIG. 5) of the pair of plate materials 1, 1. This is the part that stands out. The direction in which the engaging convex portion 220 extends is along the horizontal plane when the corner board cover 200 is attached to the pair of boards 1, 1. The engagement convex portion 220 is formed to extend across both the first covering portion 211 and the second covering portion 212 at a height position between the base end portion 210A and the distal end portion 210B.

Like the back plate part 130 in the fourth embodiment, the back plate part 230 is inserted between the back surface 1B of both the plate materials 1, 1 and the wall surface W (see FIG. 5), and is inserted into the plate material together with the surface covering part 210. This is the part that sandwiches 1 and 1 from both sides.

The back plate portion 230 includes a first back plate portion 231 and a second back plate portion 232. The first back plate portion 231 is a portion that covers the back surface 1B of one of the pair of plate materials 1 shown in FIG. be. The second back plate portion 232 is a portion that covers the back surface 1B of the other plate material 1, and is a portion that faces the second covering portion 212 of the surface covering portion 210. The first back plate portion 231 and the second back plate portion 232 are arranged such that their normal directions are perpendicular to each other.

The end portion of the back plate portion 230 on the base end portion 210A side (the upper end portion in FIG. 45) is also referred to as “end portion 230A” below. The end portion 230A is connected to the base end portion 210A of the surface covering portion 210. The end portion of the back plate portion 230 on the tip portion 210B side (the lower end portion in FIG. 45) is also referred to as “end portion 230B” below.

As shown in FIG. 45(B), the length of the surface covering portion 210 along the direction from the distal end portion 210B side to the proximal end portion 210A side (that is, the vertical direction) is equal to the length of the surface covering portion 210 along the same direction. It is longer than the length of section 230. Therefore, the position of the end portion 230B along the vertical direction is between the base end portion 210A and the distal end portion 210B.

The connecting portion 240 is a portion provided to connect the surface covering portion 210 and the back plate portion 230, similar to the connecting portion 140 in the fourth embodiment. As shown in FIGS. 46(A), 46(C), and 46(F), the connecting portion 240 of this embodiment is also formed in a plate shape.

Further, as shown in FIG. 46(F), the connecting portion 240 connects the first back plate in the vicinity of the corner portion of the surface covering portion 210 that is the boundary between the first covering portion 211 and the second covering portion 212. It is arranged so as to be parallel to the section 231. Note that, as shown in FIGS. 45(B), 46(A), etc., a rectangular through hole 250 is formed in the back plate portion 230. The through hole 250 is a punching hole formed to prevent undercuts when forming the corner plate material cover 200 by injection molding of resin.

The positional relationship between the connecting portion 240 and the engaging convex portion 220 in the vertical direction is the same as the positional relationship between the connecting portion 140 and the engaging convex portion 120 in the fourth embodiment, as described with reference to FIG. be.

Although not shown in the drawings, in this embodiment as well, the engagement convex portion 220 is the part that is furthest back toward the back plate portion 230, and has a bottom portion parallel to the back plate portion 230 and a base portion relative to the bottom portion. It has a side wall part that is connected from the end part 210A side and is inclined with respect to the back plate part 230. The end portion 241 of the connecting portion 240 closest to the tip portion 210B is located at the same position as the boundary between the bottom portion and the side wall portion (corresponding to the dotted line DL2 in FIG. 41), or at the same position along the vertical direction. It is sufficient that the base end portion 210A is disposed at a position closer to the proximal end portion 210A than the base end portion 210A. However, from the viewpoint of easily causing elastic deformation similar to that shown in FIG. It is preferable that they be arranged at the same position (corresponding to the dotted line DL1 in FIG. 41) or at a position closer to the base end portion 210A than the position. That is, it is preferable that the connecting portion 240 is formed at a position that does not overlap the engaging convex portion 220 at all along the vertical direction. Furthermore, from the viewpoint of appropriately suppressing elastic deformation that would cause separation between the surface covering part 210 and the back plate part 230, the end part 241 is arranged at a position corresponding to the dotted line DL1 in FIG. Preferably.

By arranging the connecting portion 240 at the position as described above, the same effect as that described in the fourth embodiment can be achieved even with the corner board cover 200. In addition, also in the joint plate cover like the third embodiment, by providing a plate-shaped connecting portion similar to the connecting portion 140 and the connecting portion 240, the same effect can be achieved.

In addition, regarding the protruding corner board cover 100 according to the fourth embodiment, the inside corner board cover 200 according to the fifth embodiment, and the joint board cover as described above, each modification in the first to third embodiments is applicable. For example, it is possible to apply a configuration in which the tip portion of the back plate portion is tapered, a configuration in which the back plate portion is provided with a hook portion, etc.
