[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-186132 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional protective cover 23, when attaching or detaching the lid body 25 to the base 24 fixed to the floor surface 21a, the fitting portion between the first fitting groove 24a and the first fitting protrusion 25a is close to the wall surface 21b, and the wall surface 21b gets in the way, making the attachment or detachment difficult.

[0005] This invention has been made to solve the above-mentioned conventional drawbacks, and its purpose is to provide a protective cover and an arrangement path forming device that allows the cover body to be easily attached and detached from the base body. [Means for solving the problem]

[0006] In order to achieve the above object, the protective cover and the wiring path forming device according to the present invention have the following configuration: The protective cover according to the invention of claim 1 is a protective cover placed in a corner area formed by two wall surfaces of a building. This protective cover includes a base body having two base portions along each of the two wall surfaces, and a cover body assembled to the base body to form an internal wiring and piping routing path. An upright wall is provided on one of the two wall surfaces, on the side of one of the two base portions along that wall surface away from the other of the two wall surfaces, facing the one of the two wall surfaces. The cover body is provided with an overlapping portion that overlaps the upright wall on the outer side, away from the other wall surface. A one-side assembly portion is provided at the opposing location of the upright wall and the overlapping portion to engage with each other and prevent the overlapping portion from moving away from the one of the wall surfaces. Furthermore, on the other wall surface side, the other of the two base portions along the other wall surface is provided with a gap-forming portion that faces the other wall surface and forms a gap between the other wall surface and the other wall surface. The cover body is provided with an insertion piece that can be inserted into the gap. The gap-forming portion and the insertion piece constitute the other-side assembly portion, and engagement between the gap-forming portion and the insertion piece inserted into the gap restricts the insertion piece from moving away from the other wall surface relative to the other base portion. The one-side assembly portion includes an engaged portion provided on the upright wall and an engaging portion provided on the overlapping portion, and the engaged state is established when the overlapping portion approaches the upright wall from the outside and released when the overlapping portion moves away from the upright wall. The gap-forming portion is elastically deformable so as to allow the cover body to move or rotate to a position where the engaged state of the one-side assembly portion is released when the insertion piece is inserted into the gap.

[0007] According to this protective cover, the protective cover includes a base body and a cover body, and is disposed in a recessed corner region formed by two wall surfaces. The base body has two base portions along each of the two wall surfaces. The base body has an upright wall on one of the base portions along one wall surface, away from the other wall surface, and the cover body has an overlapping portion that overlaps the upright wall on the outer side, away from the other wall surface. The upright wall has an engaged portion, and the overlapping portion has an engaging portion. The engaged portion and the engaging portion form a one-side assembly portion, and the overlapping portion engages when it approaches the upright wall from the outside and releases the engaged state when it moves away from the upright wall. Furthermore, on the other wall surface side, the base body has a gap-forming portion at the other base portion along the other wall surface, facing the other wall surface to form a gap between the other wall surface and the other wall surface. The cover body has an insertion piece that can be inserted into the gap, and the gap-forming portion and the insertion piece form the other-side assembly portion. The gap-forming portion is formed to be elastically deformable so as to allow the cover body to move or rotate to a position where the locked state of the one-side assembly portion is released with the insertion piece inserted into the gap. Therefore, when the cover body is to be removed from the base body with the base body fixed to a wall surface, the cover body is moved (more specifically, moved in a direction away from the other wall surface) or rotated (more specifically, rotated so that the side of the cover body away from the other wall surface is away from the one wall surface) to release the locked state of the one-side assembly portion, and then the insertion piece of the cover body can be removed from the base body by pulling it out of the gap formed by the gap-forming portion of the base body.When assembling the cover body to the base body while the base body is fixed to a wall surface, the insertion piece of the cover body is inserted into the gap and the cover body is moved (more specifically, moved in a direction away from the other wall surface), or the cover body is rotated (more specifically, rotated in a direction so that the side of the cover body closer to the other wall surface approaches one wall surface) so that the overlapping portion of the cover body faces the upright wall of the base body, and then the movement or rotation of the cover body is returned to its original position (more specifically, moved in a direction so that the side of the cover body farther from the other wall surface approaches one wall surface), and the one-side assembly portion is placed in an engaged state, thereby assembling the cover body to the base body.

[0008] Furthermore, the protective cover according to the invention of claim 2 is the protective cover of claim 1, wherein the standing wall and the overlapping portion face each other in the direction of elastic deformation of the gap forming portion, and the restoring force from the elastic deformation of the gap forming portion urges the overlapping portion, which tends to move away from the standing wall, toward the standing wall.

[0009] The protective cover according to the invention of claim 3 is the protective cover of claim 1 or 2, wherein the gap forming portion is provided with another locked portion, and the insertion piece is provided with another locking portion, and these other locked portion and other locking portion engage with each other to prevent the insertion piece from slipping out of the gap. The gap forming portion is elastically deformable so that the other locking portion can pass over the other locked portion.

[0010] Furthermore, the protective cover according to the invention described in claim 4 is the protective cover described in claim 1 or 2, wherein the tip of the gap forming portion faces in a direction away from the one wall surface, and an opening portion is provided on the tip side that connects the gap to the outside so that the insertion piece can be inserted into the gap from the tip side.

[0011] The protective cover according to claim 5 is the protective cover according to claim 1 or 2, wherein a plurality of the locking portions of the one-side assembly portion and a plurality of the insertion pieces of the other-side assembly portion are arranged at intervals in the direction in which the installation path extends, and the locking portions and the insertion pieces are arranged in positions facing each other across the installation path. By providing a plurality of locking portions and insertion pieces facing each other, the base body and the cover body can be firmly assembled to each other, and by spacing the plurality of locking portions and insertion pieces, assembly is made easier.

[0012] The wiring path forming device according to the invention of claim 6 comprises the protective cover of claim 1 or 2 and a protective duct having a wiring / piping path therein. Here, the protective cover has a connection port to which the protective duct can be connected. With the protective duct in a predetermined position relative to the fixed base body, the cover body can be assembled to the base body without interfering with the protective duct. This allows the base body and protective duct to be installed first, and then the cover body to be assembled to the base body.

[0013] The protective cover according to claim 7 is a protective cover placed in an interior corner area formed by two wall surfaces of a building. This protective cover includes a base body having two base portions along each of the two wall surfaces, and a cover body assembled to the base body to form an internal wiring and piping routing path. An upright wall is provided on one of the two wall surfaces, on the side of one of the two base portions along that wall surface away from the other of the two wall surfaces, facing the one of the two wall surfaces. The cover body is provided with an overlapping portion that overlaps the upright wall on the outside in the direction of extension of the interior corner area. A one-side assembly portion is provided at the opposing location of the upright wall and the overlapping portion to engage with each other and prevent the overlapping portion from moving away from the one wall surface. Furthermore, on the other wall surface side, the other of the two base portions along the other wall surface is provided with a gap-forming portion that faces the other wall surface and forms a gap between the other wall surface and the other base surface. An insertion piece that can be inserted into the gap is provided on the cover body. The gap-forming portion and the insertion piece constitute an other-side assembly portion, and engagement between the gap-forming portion and the insertion piece inserted into the gap restricts movement of the insertion piece away from the other wall surface relative to the other base portion. The one-side assembly portion also includes an engaged portion provided on the standing wall and an engaging portion provided on the overlapping portion, and the overlapping portion is engaged when it approaches the standing wall from the outside and disengages when it moves away from the standing wall. The gap forming portion is formed to be elastically deformable so as to allow the cover body to rotate in a direction in which the side of the cover body away from the other wall surface moves away from the one wall surface until, when the insertion piece is inserted into the gap, the locking portion rides up onto the locked portion and the lock between the two is released.

[0014] According to this protective cover, the protective cover includes a base body and a cover body, and is disposed in a recessed corner region formed by two wall surfaces. The base body has two base portions along each of the two wall surfaces. The base body has an upright wall on one side of the base portion along one wall surface, away from the other wall surface. The cover body has an overlapping portion that overlaps the upright wall on the outer side in the direction of extension of the recessed corner region. The upright wall has an engaged portion and the overlapping portion has an engaging portion. The engaged portion and the engaging portion form a one-side assembly portion, and the overlapping portion engages when it approaches the upright wall from the outside and releases the engaged state when it moves away from the upright wall. Furthermore, on the other wall surface side, the base body has a gap-forming portion at the other base portion along the other wall surface, facing the other wall surface to form a gap between the other wall surface and the other wall surface. The cover body has an insertion piece that can be inserted into the gap, and the gap-forming portion and the insertion piece form the other-side assembly portion. The gap-forming portion is formed to be elastically deformable so as to allow the cover body to rotate with the insertion piece inserted into the gap until the locking portion rides up on the locked portion and the lock between them is released. Therefore, when the cover body is to be removed from the base body with the base body fixed to a wall surface, the cover body is rotated (more specifically, the side of the cover body away from the other wall surface is rotated in the direction away from one wall surface) to release the lock between the locking portion and the locked portion, thereby releasing the locked state of the one-side assembly portion, and then the insertion piece of the cover body can be removed from the base body by pulling out the gap formed by the gap-forming portion of the base body. When assembling the cover body to the base body while the base body is fixed to the wall surface, the cover body is rotated by inserting the insertion piece of the cover body into the gap (more specifically, by rotating the side of the cover body closer to the other wall surface toward one wall surface), and then the cover body is rotated back so that the side of the cover body away from the other wall surface approaches one wall surface, thereby engaging the locking portion with the locked portion, and thereby putting one side assembly portion into an engaged state, and the cover body can be assembled to the base body. [Effects of the Invention]

[0015] According to the protective cover and arrangement path forming device of this invention, a gap forming portion is provided on the base body to form a gap between the base body and the other wall surface, and by elastically deforming the gap forming portion, the cover body can be easily attached and detached to the base body fixed to the wall surface.

DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0018] 1 to 15 show a first embodiment of the present invention. In the drawings, reference numeral 1 denotes an inside corner area, which is formed by two wall surfaces 1a and 1b of a building. 2 denotes a protective cover placed in the inside corner area 1. 3 denotes a protective duct. 4 denotes an installation path forming device.

[0019] The protective cover 2 comprises a base body 5 having two base portions 5a, 5b along the two wall surfaces 1a, 1b, respectively, and a cover body 6 which is assembled with the base body 5 to form an interior route L for wiring and piping materials (wiring or piping materials). Here, the wall surfaces 1a, 1b are made up of vertical wall surfaces, floor wall surfaces, ceiling wall surfaces, etc., and the inside corner area 1 is made up of an upper inside corner area where the ceiling wall surface and the vertical wall surface intersect, a lower inside corner area where the vertical wall surface and the floor wall surface intersect, and a vertical inside corner area where the vertical wall surfaces intersect.

[0020] On the side of one wall 1a of the two wall surfaces 1a, 1b, one of the two base portions 5a, 5b that extend along the one wall surface 1a is provided with a first standing wall 5c that stands on the side of the one base portion 5a that is away from the other wall surface 1b of the two wall surfaces 1a, 1b. Meanwhile, the cover body 6 is provided with a first overlapping portion 6a that overlaps the outer side of the first standing wall 5c, that is, the side that is away from the other wall surface 1b. Then, a first one-side assembly portion 2a is provided where the first standing wall 5c and the first overlapping portion 6a face each other to engage with each other so as to restrict movement of the first overlapping portion 6a away from the one wall surface 1a relative to the first standing wall 5c.

[0021] Furthermore, on the other wall surface 1b side, a gap forming portion 5e is provided on the other base portion 5b of the two base portions 5a, 5b along the other wall surface 1b so as to face the other wall surface 1b and form a gap 5d between the other wall surface 1b and the other base portion 5b. An insertion piece 6b that can be inserted into the gap 5d is provided on the cover body 6. The gap forming portion 5e and the insertion piece 6b constitute the other-side assembling portion 2b, and engagement between the gap forming portion 5e and the insertion piece 6b inserted into the gap 5d restricts movement of the insertion piece 6b (i.e., the cover body 6) away from the other wall surface 1b relative to the other base portion 5b (i.e., the base body 5).

[0022] Furthermore, the first one-side assembly portion 2a is composed of a first locked portion 5f provided on the first standing wall 5c of the base body 5 and a first locking portion 6c provided on the first overlapping portion 6a of the cover body 6, and is engaged when the first overlapping portion 6a approaches the first standing wall 5c from the outside, and is released from the engaged state when it moves away. Therefore, with the insertion piece 6b of the cover body 6 inserted into the gap 5d, the gap-forming portion 5e of the base body 5 is formed to be elastically deformable so as to allow the cover body 6 to move (more specifically, move in a direction away from the other wall surface 1b) or rotate (more specifically, rotate the side of the cover body 6 away from the other wall surface 1b in a direction away from the one wall surface 1a) to a position where the locked state of the first one-side assembly portion 2a is released. The first standing wall 5c and the first overlapping portion 6a face each other in the direction of elastic deformation of the gap forming portion 5e, and the restoring force from the elastic deformation of the gap forming portion 5e urges the first overlapping portion 6a, which is trying to move away from the first standing wall 5c, toward the first standing wall 5c.

[0023] The protective cover 2 further includes a second standing wall 5g, a second overlapping portion 6d, and a second one-side assembly portion 2c. The second standing wall 5g stands on the side of one wall 1a, away from the other wall 1b of one base portion 5a that runs along the one wall 1a. The second overlapping portion 6d is provided on the cover body 6 and overlaps the outside of the second standing wall 5g in the direction in which the recessed corner region 1 extends. The second one-side assembly portion 2c engages with the second standing wall 5g at a location where the second overlapping portion 6d faces the second standing wall 5g to prevent the second overlapping portion 6d from moving away from the one wall 1a. Specifically, the second one-side assembly portion 2c includes a second locked portion 5h provided on the second standing wall 5g and a second locking portion 6e provided on the second overlapping portion 6d, and is locked when the second overlapping portion 6d approaches the second standing wall 5g from the outside, and is released from the locked state when the second overlapping portion 6d moves away from the second standing wall 5g. The gap-forming portion 5e is formed to be elastically deformable so as to allow the side of the cover body 6 away from the other wall surface 1b (i.e., the side where the second overlapping portion 6d is provided) to rotate in a direction away from the one wall surface 1a, until the second locking portion 6e rides on the second locked portion 5h and the lock between them is released, with the insertion piece 6b inserted into the gap 5d.

[0024] The wiring path forming device 4 comprises the protective cover 2 and a protective duct 3 having an interior wiring path L for wiring and piping materials (wiring or piping materials). Here, the protective cover 2 has a connection port 2d to which the protective duct 3 can be connected. Then, with the protective duct 3 placed in a predetermined position (a connecting position) relative to a fixed base body 5 (more specifically, fixed to wall surfaces 1a and 1b), the cover body 6 can be assembled to the base body 5 without interfering with the protective duct 3.

[0025] Specifically, the protective cover 2 (more specifically, the base body 5 and the cover body 6) are formed in a T-shape. The protective cover 2 is disposed so that the portion corresponding to the horizontal line of the T is aligned with the inside corner region 1, and the portion corresponding to the vertical line of the T is aligned with one wall surface 1a. The first standing wall 5c, the first overlapping portion 6a, the first one-side assembly portion 2a, and the other-side assembly portion 2b (i.e., the gap forming portion 5e and the insertion piece 6b) are provided in the portion corresponding to the horizontal line of the T, and the second standing wall 5g, the second overlapping portion 6d, and the second one-side assembly portion 2c are provided in the portion corresponding to the vertical line of the T.

[0026] In the base body 5, one base portion 5a along one wall surface 1a is formed in a flat T-shape, and the other base portion 5b along the other wall surface 1b is formed in a flat, linear shape. The one base portion 5a and the other base portion 5b are connected by a connecting portion 5i that is inclined to be chamfered. As shown in FIG. 7, a first upright wall 5c stands up from the end of the portion of the one base portion 5a that corresponds to the horizontal line of the T, closer to the portion that corresponds to the vertical line of the T, and a second upright wall 5g stands up from both ends of the width of the portion that corresponds to the vertical line of the T. A gap-forming portion 5e is formed at the end of the other base portion 5b that is farther from the one base portion 5a by bending from the other base portion 5b. The tip of this gap forming portion 5e faces away from one wall surface 1a, and an opening portion 5j is provided at the tip side to connect the gap 5d to the outside so that the insertion piece 6b can be inserted into the gap 5d from the tip side.

[0027] 10, the cover body 6 has a substantially L-shaped cross section at a portion corresponding to the horizontal line of the T, with the corners formed in an arc, one end of the L forming a first overlapping portion 6a, and an insertion piece 6b hanging down from the other end of the L. The first locking portion 6c is provided within a partial range of the first overlapping portion 6a, and multiple first locking portions 6c and insertion pieces 6b are arranged at intervals in the direction in which the installation path L extends, and the first locking portions 6c and insertion pieces 6b are arranged in positions facing each other across the installation path L.

[0028] The cover body 6 has a section corresponding to the vertical line of the T formed in an inverted U-shape, and both lower end portions of the inverted U form second overlapping portions 6d. The second locking portions 6e are provided in partial ranges of the second overlapping portions 6d, 6d so as to face each other across the installation path L.

[0029] Each end of the T-shape of the cover body 6 (protective cover 2) serves as the connection port 2d. Therefore, FIGS. 1 and 2 show an example in which a protective duct 3 is connected to each connection port 2d. Here, the protective duct 3 is a linear protective duct. A first protective duct 301 serving as the protective duct 3 is connected to the connection port 2d at each end of the portion of the cover body 6 (protective cover 2) that corresponds to the horizontal line of the T-shape, and a second protective duct 302 serving as the protective duct 3 is connected to the connection port 2d at the tip of the portion that corresponds to the vertical line of the T-shape.

[0030] In the first one-side assembly portion 2a, the first locked portion 5f provided on the first standing wall 5c and the first locking portion 6c provided on the first overlapping portion 6a are formed to protrude on the side where the first standing wall 5c and the first overlapping portion 6a face each other. Similarly, in the second one-side assembly portion 2c, the second locked portion 5h provided on the second standing wall 5g and the second locking portion 6e provided on the second overlapping portion 6d are formed to protrude on the side where the second standing wall 5g and the second overlapping portion 6d face each other.

[0031] In the other assembly part 2b, the gap forming part 5e is provided with another locked part 5k, and the insertion piece 6b is provided with another locking part 6f, and these other locked part 5k and other locking part 6f engage with each other to prevent the insertion piece 6b from slipping out of the gap 5d. More specifically, the other locked part 5k and other locking part 6f are formed to protrude on the side facing the gap forming part 5e and the insertion piece 6b. The gap forming part 5e is elastically deformable so that the other locking part 6f can pass over the other locked part 5k.

[0032] Meanwhile, the protective cover 2 has an engagement recess 7 (more specifically, a linearly extending groove-shaped recess) on its back surface (more specifically, the back surface of the bases 5a and 5b) for aligning with the spacer 9. The spacer 9 is interposed between the wall surfaces 1a and 1b and the protective cover 2 (more specifically, the bases 5a and 5b) to raise the height of the protective cover 2 relative to the wall surfaces 1a and 1b. Here, one base 5a is formed in a flat T-shape as described above, and a first engagement recess 7a as the engagement recess 7 is provided on the back surface of a portion corresponding to a horizontal line thereof so as to extend in the longitudinal direction thereof, and a second engagement recess 7b as the engagement recess 7 is provided on the back surface of a portion corresponding to a vertical line thereof so as to extend in the longitudinal direction thereof, and this second engagement recess 7b extends until it intersects with the first engagement recess 7a. The other base portion 5b is formed in a flat, linear shape as described above, and is provided on its rear surface with the third engaging recess 7c as the engaging recess 7, extending in the longitudinal direction thereof.

[0033] Similarly, the protective duct 3 is provided with an engagement recess 8 (more specifically, a linearly extending groove-shaped recess) for alignment with the spacer 9 (more specifically, alignment in a direction perpendicular to the linear extension direction of the protective duct 3 and the spacer 9). The spacer 9 is interposed between the wall surfaces 1a, 1b and the protective duct 3 to raise the protective duct 3 above the wall surfaces 1a, 1b. As described above, the protective duct 3 is a linear protective duct. The first protective duct 301 as the protective duct 3 is provided with a first engagement recess 8a as an engagement recess 8 on its back surface along one wall surface 1a so as to extend in the longitudinal direction, and a third engagement recess 8c as an engagement recess 8 on its back surface along the other wall surface 1b so as to extend in the longitudinal direction. The first engagement recess 8a is provided so as to communicate with the first engagement recess 7a of the protective cover 2, and the third engagement recess 8c is provided so as to communicate with the third engagement recess 7c of the protective cover 2. Furthermore, the second protective duct 302 as the protective duct 3 is provided with a second engaging recess 8b as the engaging recess 8 on the back surface along one wall surface 1a so as to extend in the longitudinal direction thereof. The second engaging recess 8b is provided so as to be continuous with the second engaging recess 7b of the protective cover 2.

[0034] As shown in Figures 13 and 14, in the spacer 9, a first spacer 901 as the spacer 9 is interposed between one wall surface 1a and the first protective duct 301 (and the protective cover 2, more specifically, the part corresponding to the horizontal line of the T on one base 5a), a second spacer 902 as the spacer 9 is interposed between one wall surface 1a and the second protective duct 302 (and the protective cover 2, more specifically, the part corresponding to the vertical line of the T on one base 5a), and a third spacer 903 as the spacer 9 is interposed between the other wall surface 1b and the first protective duct 301 (and the protective cover 2, more specifically, the other base 5b). The upper surface of the first spacer 901 is provided with a first engaging protrusion 9a that engages with the first engaging recesses 8a and 7a, the upper surface of the second spacer 902 is provided with a second engaging protrusion 9b that engages with the second engaging recesses 8b and 7b, and the upper surface of the third spacer 903 is provided with a third engaging protrusion 9c that engages with the third engaging recesses 8c and 7c.

[0035] Here, the spacer 9 raises the protective duct 3, but also extends to the protective cover 2, raising the protective cover 2 as well. The engagement recesses 7a, 7b, and 7c provided on the protective cover 2 also serve as avoidance spaces that avoid interference with the engagement protrusions 9a, 9b, and 9c of the spacer 9. The first engagement recess 7a and the second engagement recess 7b of the protective cover 2 are arranged to intersect with each other. Regarding the first spacer 901 and the second spacer 902, the first spacer 901 can be arranged to span the entire portion of the protective cover 2 that corresponds to the horizontal line of the T on one base 5a (see FIG. 15(a)), or the second spacer 902 can be arranged to extend from the portion that corresponds to the vertical line of the T on one base 5a until it intersects with the portion that corresponds to the horizontal line of the T (see FIG. 15(b)).

[0036] Next, the effects of the protective cover 2 and the installation path forming device 4 shown in the first embodiment will be described. The protective cover 2 includes a base body 5 and a cover body 6, and is placed in the recessed corner region 1 formed by two wall surfaces 1a and 1b. The base body 5 has two base portions 5a and 5b along the two wall surfaces 1a and 1b, respectively. The base body 5 is provided with a first standing wall 5c on the side of one base portion 5a along one wall surface 1a, away from the other wall surface 1b, and the cover body 6 is provided with a first overlap portion 6a overlapping the outer side of the first standing wall 5c, that is, on the side away from the other wall surface 1b. A first engaging portion 5f is provided on the first standing wall 5c, and a first engaging portion 6c is provided on the first overlapping portion 6a, and these first engaging portion 5f and first engaging portion 6c form the first one-side assembly portion 2a, and the first overlapping portion 6a enters an engaged state when it approaches the first standing wall 5c from the outside, and the engaged state is released when it moves away.

[0037] On the other wall surface 1b side, the base body 5 is provided with a gap-forming portion 5e at the other base portion 5b along the other wall surface 1b, which faces the other wall surface 1b and forms a gap 5d between the other wall surface 1b and the other base portion 5b, and the cover body 6 is provided with an insertion piece 6b that can be inserted into the gap 5d, and the gap-forming portion 5e and the insertion piece 6b constitute the other-side assembly part 2b. With the insertion piece 6b inserted into the gap 5d, the gap-forming portion 5e is formed to be elastically deformable so as to allow the cover body 6 to move (more specifically, move in a direction away from the other wall surface 1b) or rotate (more specifically, rotate the side of the cover body 6 away from the other wall surface 1b in a direction away from the one wall surface 1a) to a position where the locked state of the first one-side assembly part 2a is released.

[0038] Therefore, when the cover body 6 assembled to the base body 5 is to be removed from the base body 5 while the base body 5 is fixed to the wall surfaces 1a and 1b, the cover body 6 is moved (more specifically, moved in a direction away from the other wall surface 1b) or rotated (more specifically, rotated so that the side of the cover body 6 away from the other wall surface 1b is away from one wall surface 1a) to release the locked state of the first one-side assembly portion 2a, and then the insertion piece 6b of the cover body 6 is pulled out from the gap 5d formed by the gap forming portion 5e of the base body 5, thereby removing the cover body 6 from the base body 5. When assembling the cover body 6 to the base body 5 while the base body 5 is fixed to the wall surfaces 1a and 1b, the insertion piece 6b of the cover body 6 is inserted into the gap 5d and the cover body 6 is moved (more specifically, moved in the direction away from the other wall surface 1b), or the cover body 6 is rotated (more specifically, rotated in the direction so that the side of the cover body 6 closer to the other wall surface 1b approaches the one wall surface 1a) so that the insertion piece 6b of the cover body 6 is inserted into the gap 5d, so that the first overlapping portion 6a of the cover body 6 faces the first upright wall 5c of the base body 5, and then the movement or rotation of the cover body 6 is returned to its original position (more specifically, moved in the direction so that the side of the cover body 6 away from the other wall surface 1b approaches the one wall surface 1a), and the first one-side assembly portion 2a is put into an engaged state, thereby assembling the cover body 6 to the base body 5. That is, the base body 5 is provided with a gap forming portion 5e that forms a gap 5d between it and the other wall surface 1b, and by elastically deforming the gap forming portion 5e, the cover body 6 can be easily attached and detached to the base body 5 fixed to the wall surfaces 1a and 1b.

[0039] The protective cover 2 also includes a second standing wall 5g, a second overlapping portion 6d, and a second one-side assembly portion 2c (the second locked portion 5h and the second locking portion 6e), and the second overlapping portion 6d is provided so as to overlap the outer side of the second standing wall 5g in the extension direction of the recessed corner area 1. The gap-forming portion 5e is formed to be elastically deformable so as to allow the cover body 6 to rotate (more specifically, the side of the cover body 6 away from the other wall surface 1b rotates in the direction away from the one wall surface 1a) until the second locking portion 6e rides up onto the second locked portion 5h and the lock between them is released when the insertion piece 6b is inserted into the gap 5d. Therefore, when the cover body 6 assembled to the base body 5 is to be removed from the base body 5 while the base body 5 is fixed to the wall surfaces 1a and 1b, the cover body 6 is rotated (more specifically, the side of the cover body 6 away from the other wall surface 1b is rotated in the direction away from one wall surface 1a) to release the engagement between the second engaging portion 6e and the second engaged portion 5h, thereby releasing the engaged state of the second one-side assembly portion 2c, and then the insertion piece 6b of the cover body 6 is pulled out from the gap 5d formed by the gap forming portion 5e of the base body 5, thereby allowing the cover body 6 to be removed from the base body 5. When the cover body 6 is to be assembled to the base body 5 while the base body 5 is fixed to the wall surfaces 1a and 1b, the cover body 6 is rotated so that the insertion piece 6b of the cover body 6 is inserted into the gap 5d (more specifically, the side of the cover body 6 closer to the other wall surface 1b is rotated in the direction approaching the one wall surface 1a), and then the cover body 6 is rotated back so that the side of the cover body 6 away from the other wall surface 1b is brought closer to the one wall surface 1a, and the second engaging portion 6e is engaged with the second engaged portion 5h, thereby putting the second one-side assembly portion 2c into an engaged state, and the cover body 6 can be assembled to the base body 5. In other words, even if the protective cover 2 is provided with the second standing wall 5g, the second overlapping portion 6d, and the second one-side assembly portion 2c, the base body 5 is provided with a gap forming portion 5e that forms a gap 5d between it and the other wall surface 1b, and by elastically deforming the gap forming portion 5e, the cover body 6 can be easily attached and detached to the base body 5 fixed to the wall surfaces 1a and 1b.

[0040] Furthermore, the first standing wall 5c and the first overlapping portion 6a face each other in the direction of elastic deformation of the gap forming portion 5e, and the restoring force from the elastic deformation of the gap forming portion 5e urges the first overlapping portion 6a, which tries to move away from the first standing wall 5c, toward the first standing wall 5c. This ensures that the first locked portion 5f provided on the first standing wall 5c and the first locking portion 6c provided on the first overlapping portion 6a are locked to each other, stabilizing the locked state of the first one-side assembly portion 2a.

[0041] Further, another locked portion 5k is provided on the gap forming portion 5e of the base body 5, and another locking portion 6f is provided on the insertion piece 6b of the cover body 6. Therefore, these other locked portion 5k and other locking portion 6f engage with each other to prevent the insertion piece 6b from slipping out of the gap 5d, thereby stabilizing the engagement state between the gap forming portion 5e and the insertion piece 6b.

[0042] Furthermore, the tip of the gap forming portion 5e of the base body 5 faces in a direction away from one wall surface 1a, and an opening 5j that connects the gap 5d to the outside is provided on the tip side. By moving the insertion piece 6b (cover body 6) toward one wall surface 1a so that the insertion piece 6b is aligned with the other wall surface 1b, the insertion piece 6b can be inserted into the gap 5d from the opening 5j on the tip side of the gap forming portion 5e, facilitating the assembly work.

[0043] Furthermore, the first locking portions 6c of the first one-side assembly portion 2a and the insertion pieces 6b of the other-side assembly portion 2b are arranged at intervals in the direction in which the installation path L extends, and the first locking portions 6c and the insertion pieces 6b are arranged in positions facing each other across the installation path L. By providing a plurality of first locking portions 6c and insertion pieces 6b and facing each other, the base body 5 and the cover body 6 can be firmly assembled to each other, and by providing a gap between the plurality of first locking portions 6c and insertion pieces 6b, assembly becomes easier.

[0044] The protective cover 2 also has a connection port 2d to which the protective duct 3 can be connected. Then, with the protective duct 3 placed in a predetermined position (connecting position) with respect to the fixed base body 5, the cover body 6 can be assembled to the base body 5 without interfering with the protective duct 3. Therefore, the base body 5 and the protective duct 3 can be installed first, and then the cover body 6 can be assembled to the base body 5.

[0045] 16 to 20 show a second embodiment of the present invention. In this embodiment, the first standing wall 5c, the first overlapping portion 6a, and the first one-side assembly portion 2a (the first locked portion 5f and the first locking portion 6c) are omitted from the protective cover 2 shown in the first embodiment, but the rest is the same, and the following description will mainly focus on the different portions, with the same reference numerals used to denote the same parts.

[0046] This protective cover 2 has a shape in which the part of the T-shape corresponding to the horizontal line that extends beyond the part corresponding to the vertical line is removed, and the part corresponding to the vertical line is extended until it hits the other wall surface 1b, as compared to the protective cover 2 shown in the first embodiment.

[0047] This protective cover 2 is placed in an inside corner area 1 formed by two wall surfaces 1a, 1b of a building, and comprises a base body 5 having two base portions 5a, 5b along each of the two wall surfaces 1a, 1b, and a cover body 6 which is assembled with the base body 5 to form an internal wiring and piping (wiring or piping) routing path L. Here, an opening 5m is formed in the base body 5, and the opening 5m communicates with a wall hole (not shown) formed in one wall surface 1a or the other wall surface 1b, and the wiring and piping routing path L continues into the wall hole.

[0048] On the side of one wall 1a of the two wall surfaces 1a, 1b, one of the two base portions 5a, 5b that extend along the one wall surface 1a is provided with a second standing wall 5g that stands on the side of the one base portion 5a that is away from the other wall surface 1b of the two wall surfaces 1a, 1b. Meanwhile, the cover body 6 is provided with a second overlapping portion 6d that overlaps the second standing wall 5g on the outside in the direction in which the recessed corner region 1 extends. A second one-side assembly portion 2c that engages with the second standing wall 5g is provided at a location where the second overlapping portion 6d faces the second standing wall 5g so as to restrict movement of the second overlapping portion 6d away from the one wall surface 1a relative to the second standing wall 5g.

[0049] Furthermore, on the other wall surface 1b side, a gap forming portion 5e is provided on the other base portion 5b of the two base portions 5a, 5b along the other wall surface 1b so as to face the other wall surface 1b and form a gap 5d between the other wall surface 1b and the other base portion 5b. An insertion piece 6b that can be inserted into the gap 5d is provided on the cover body 6. The gap forming portion 5e and the insertion piece 6b constitute the other-side assembling portion 2b, and engagement between the gap forming portion 5e and the insertion piece 6b inserted into the gap 5d restricts movement of the insertion piece 6b (i.e., the cover body 6) away from the other wall surface 1b relative to the other base portion 5b (i.e., the base body 5).

[0050] The second one-side assembly portion 2c is composed of a second locked portion 5h provided on the second standing wall 5g of the base body 5 and a second locking portion 6e provided on the second overlapping portion 6d of the cover body 6, and is locked when the second overlapping portion 6d approaches the second standing wall 5g from the outside, and is released from the locked state when the second overlapping portion 6d moves away from the second standing wall 5g. Therefore, with the insertion piece 6b of the cover body 6 inserted into the gap 5d, the gap-forming portion 5e is formed to be elastically deformable so as to allow the side of the cover body 6 away from the other wall surface 1b (i.e., the side where the second overlapping portion 6d is provided) to rotate in a direction away from the one wall surface 1a until the second locking portion 6e rides up on the second locked portion 5h and the lock between them is released.

[0051] The action and effect of the protective cover 2 shown in this second embodiment is the same as that of the first embodiment, but the parts relating to the first standing wall 5c, the first overlapping portion 6a, and the first one-side assembly portion 2a (the first engaged portion 5f, the first engaging portion 6c) are excluded.

[0052] The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, in the first embodiment, the protective cover 2 is formed in a T-shape. However, the protective cover 2 may be formed in an L-shape, in which the portion corresponding to the vertical line of the T is shifted to one end of the portion corresponding to the horizontal line of the T. Furthermore, the protective cover 2 may be configured such that the portion corresponding to the vertical line of the T is removed, leaving only the portion corresponding to the horizontal line of the T, and the second standing wall 5g, the second overlapping portion 6d, and the second one-side assembly portion 2c (the second locked portion 5h and the second locking portion 6e) are not provided. In this case, the protective cover 2 may be formed in an elongated shape and arranged along the recessed corner region 1. Furthermore, this elongated protective cover may be composed of an elongated base body and an elongated cover body. Alternatively, a configuration may be adopted in which multiple short base bodies are arranged at intervals, and the elongated cover bodies are assembled to the base bodies.

[0053] The protective cover 2 is provided with connection ports 2d, but the number of connection ports 2d is not limited to the number shown in the illustrated embodiment. In addition, if the protective cover 2 is a faucet cover for fixing a faucet joint installed in a wall hole, the connection ports 2d may be omitted.

[0054] Furthermore, in the other side assembly portion 2b, another engaging portion 5k is provided in the gap forming portion 5e, and another engaging portion 6f is provided in the insertion piece 6b, but these other engaging portion 5k and other engaging portion 6f may be omitted.

[0055] Furthermore, although the gap 5d is open on the other wall surface 1b side, a protruding piece may be provided on the other base 5b that faces the gap forming portion 5e at a distance and protrudes along the other wall surface 1b, so that part or all of the other wall surface 1b side is closed.

[0056] Finally, other inventions derived from the first embodiment are described below as appendices.
