Description

Technical Field

[0001] This invention relates to a protective cover device disposed in a corner region, and an installation structure of a protective cover in a corner region.

Background Art

[0002] Conventionally, there has been a wiring protective cover disposed in a corner region where the wall surfaces in a building intersect (see, for example, Patent Document 1). As shown in FIG. 28, this protective cover 23 is composed of a base 24 and a lid 25, and has a wiring accommodation space 26 for accommodating wires 22 inside. And the protective cover 23 is provided with folding-planned plates 24a and 25a protruding from the base 24 and the lid 25. Therefore, the protective cover 23 is placed on the floor surface 21a such that the tips of the folding-planned plates 24a and 25a abut against the wall surface 21b in the corner region 21 of the floor surface 21a and the wall surface 21b. At this time, since a space 27 is formed below by the folding-planned plates 24a and 25a, even if there is a foreign object 28 at the intersection of the floor surface 21a and the wall surface 21b, the protective cover 23 can be installed by abutting against the wall surface 21b without interfering with the foreign object 28.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional protective cover 23, if there is no foreign object 28 (obstacle) at the intersection of the floor surface 21a and the wall surface 21b, and the disposable plates 24a and 25a that are no longer needed are disposable, then even if the situation changes afterward and the disposable plates 24a and 25a become necessary again, it is not possible to put the disposable plates 24a and 25a back in place, and the cover cannot respond to the changed situation.

[0005] This invention was made to solve the aforementioned drawbacks of the conventional methods, and its purpose is to provide a protective cover device and a protective cover installation structure that can accurately avoid interference with obstacles. [Means for solving the problem]

[0006] The protective cover device and protective cover installation structure according to this invention have the following configuration in order to achieve the above objective. That is, This invention The protective cover device is a protective cover device that is placed in the inner corner area of ​​a wall in a building. This protective cover device forms a route for wiring and piping materials arranged along the inner corner area and comprises a protective cover having two sides that are along each of the two wall surfaces forming the inner corner area, and a spacer interposed between both or either of the two sides and the wall surface opposite to that side. Here, the width of the spacer is shorter than the distance from the outer edge of the side in which the spacer is interposed to the side intersection line where the two virtual side surfaces, including each of the bottom surfaces of each side, intersect. A configuration is proposed. .

[0007] According to this protective cover device, in the corner area, the protective cover is separated from the wall surface by the interposition of a spacer between the side of the protective cover and the wall surface forming the corner area. Because the protective cover is separated from the wall surface, even if there is an obstacle at the corner of the corner area, the protective cover can avoid interfering with that obstacle. Furthermore, the width of the spacer is shorter than the distance from the outer edge of the side where the spacer is interposed to the side intersection line where the two virtual side surfaces, each including the bottom surface of each side, intersect, so the spacer can also avoid interfering with the obstacle.

[0008] Also, This invention The protective cover device is a protective cover device that is placed in the inner corner area of ​​a wall in a building. This protective cover device forms a route for wiring and piping materials arranged along the inner corner area and comprises a protective cover having two sides that are along each of the two wall surfaces forming the inner corner area, and a spacer interposed between both or either of the two sides and the wall surface facing that side. Here, the spacer has an alignment portion that is aligned with the side on which the spacer is interposed, and in the state aligned with the side, moves away from the inner corner area intersection line where the two virtual inner corner area surfaces, including each of the two wall surfaces, intersect. A configuration is proposed. .

[0009] According to this protective cover device, in the inner corner area, the protective cover is separated from the wall surface by the interposition of a spacer between the side of the protective cover and the wall surface forming the inner corner area. Because the protective cover is separated from the wall surface, even if there is an obstacle at the corner of the inner corner area, the protective cover can avoid interference with that obstacle. Furthermore, since the spacer, while aligned with the side, is separated from the intersection line of the inner corner area where the two virtual surfaces of the inner corner area, each containing the two wall surfaces, intersect, the spacer can also avoid interference with the obstacle.

[0010] Also, This inventionIn the protective cover device, the protective cover comprises a base and a lid assembled to the base and forming the arrangement path with the base. Here, the base has two side walls constituting the two sides and a connecting portion connecting the two side walls. In the protective cover, the distance from the outer edge of each of the two sides to the side intersection line where the two virtual side surfaces, including the bottom surfaces of each side, intersect is the same for both sides. Therefore, the two side walls can be fixed to the two wall surfaces by interposing the spacer between both or either of the two sides and the wall surface facing that side. A configuration is proposed. .

[0011] Also, This invention In the protective cover device, the protective cover comprises a straight protective cover having a first side portion that constitutes the side portion and extending linearly along the inner corner region, and an attached protective cover having a second side portion that constitutes the side portion and a connection port to which the straight protective cover can be connected. The spacer is a continuous spacer arranged across the straight protective cover and the attached protective cover in a connected state. The spacer is provided with an alignment portion that is aligned with the side portion in which the spacer is interposed, and the alignment portion comprises an alignment portion for the straight protective cover that is alignable with the first side portion, and an alignment portion for the attached protective cover that is alignable with the second side portion. A configuration is proposed. .

[0012] Also, This invention In the protective cover device, the attached protective cover is formed so that both of the second sides are short and do not reach the side intersection line where the two virtual side surfaces, including each of the bottom surfaces of the second side, intersect. A configuration is proposed. .

[0013] Also, This inventionIn the protective cover device, the protective cover comprises a straight protective cover having a first side portion that constitutes the side portion and extending linearly along the inner corner region, and an auxiliary protective cover having a second side portion that constitutes the side portion and having a connection port to which the straight protective cover can be connected. The spacer comprises a straight spacer for the straight protective cover and an auxiliary spacer for the auxiliary protective cover, which is separate from the straight spacer. A configuration is proposed. .

[0014] Also, This invention The protective cover installation structure is an installation structure for a protective cover that forms an installation path for wiring and piping materials arranged along the inner corner area of ​​a wall in a building. The protective cover has an enclosing portion that surrounds the wiring and piping materials in at least a portion of its longitudinal direction. The protective cover also has two sides that are along each of the two wall surfaces that form the inner corner area, and a spacer is interposed between both or either of the two sides and the wall surface opposite to that side, so that the installation path formed by the protective cover is located away from that wall surface. Furthermore, by having the spacer move away from the intersection line of the inner corner area where the two virtual surfaces of the inner corner area, including each of the two wall surfaces, intersect, the spacer, in addition to the protective cover, avoids interference with obstacles formed at the intersection line of the inner corner area. [Effects of the Invention]

[0015] According to the protective cover device and protective cover installation structure of this invention, by providing spacers as needed, interference with obstacles at the corners of the inner corner area can be accurately avoided. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0017] Hereinafter, embodiments for carrying out this invention will be described based on the drawings.

[0018] Figures 1 to 7 show a first embodiment of the present invention. Reference numeral 1 in the figures indicates an inner corner area of ​​a wall in a building. 2 indicates wiring and piping materials (wiring materials or piping materials) arranged along the inner corner area 1. 3 indicates a protective cover device placed in the inner corner area 1. 4 indicates the installation structure of the protective cover.

[0019] The protective cover device 3 comprises a protective cover 5 and a spacer 6. The protective cover 5 forms a routing path 5a for the wiring and piping material 2 and includes two side portions 5b, 5b that run along each of the two wall surfaces 1a, 1a that form the inner corner region 1. The spacer 6 is interposed between both or either of these two side portions 5b, 5b (both in the illustrated embodiment) and the wall surface 1a facing the side portion 5b. Here, the wall surface 1a consists of a vertical wall surface, a floor wall surface, a ceiling wall surface, etc., and the inner corner region 1 consists of an upper inner corner region where the ceiling wall surface and the vertical wall surface intersect, a lower inner corner region where the vertical wall surface and the floor wall surface intersect, or a vertical inner corner region where two vertical wall surfaces intersect.

[0020] The width 6a of the spacer 6 is shorter than the distance 5f from the outer edge 5c of the side portion 5b in which the spacer 6 is interposed to the side intersection line 5e where the two virtual side surfaces 5d, 5d, which include the bottom surfaces of each side portion 5b, 5b, intersect.

[0021] Furthermore, the spacer 6 is equipped with an alignment portion 6b that is aligned with the side portion 5b (and consequently the protective cover 5) in which the spacer 6 is interposed (aligned in the width direction in the illustrated embodiment), and is formed so as to move away from the intersection line 1c of the inner corner region where the two inner corner region virtual surfaces 1b, 1b, each including the two wall surfaces 1a, 1a, intersect.

[0022] In detail, in the protective cover 5, the distances 5f, 5f from the outer edges 5c, 5c of each of the two sides 5b, 5b to the side intersection line 5e where the two virtual side surfaces 5d, 5d, including the bottom surfaces of each of the sides 5b, 5b, intersect are the same. The spacer 6 is interposed between both or either of the two sides 5b, 5b and the wall surface 1a facing that side 5b, so that the two sides 5b, 5b (more specifically, the two side walls 7a, 7a in the base 7 described later) can be fixed to the two wall surfaces 1a, 1a.

[0023] Furthermore, the protective cover 5 comprises a base 7 and a lid 8 assembled to the base 7 to form the arrangement path 5a with the base 7. The base 7 has two side walls 7a, 7a that constitute the two sides 5b, 5b (more specifically, two side walls 7a, 7a and a connecting portion 7b that connects the two side walls 7a, 7a). Specifically, the two side walls 7a, 7a (sides 5b, 5b) are formed short so as not to reach the side intersection line 5e where two side virtual surfaces 5d, 5d, including each of the bottom surfaces of each side wall 7a, 7a (each side 5b, 5b), intersect, and the connecting portion 7b connects both side walls 7a, 7a (both side parts 5b, 5b) on the side closer to the side intersection line 5e, and is positioned set back (away from) the side intersection line 5e. In the illustrated embodiment, the connecting portion 7b is formed at an inclination with respect to both side walls 7a, 7a (side portions 5b, 5b).

[0024] In the installation structure 4 for the protective cover 5, the protective cover 5 has a surrounding portion that surrounds the wiring and piping material 2 in at least a part of its longitudinal direction (over its entire length in the illustrated embodiment). In the illustrated embodiment, this surrounding portion is formed by the base 7 and the lid 8. The protective cover 5 has two side portions 5b, 5b that are along each of the two wall surfaces 1a, 1a that form the inner corner region 1, and a spacer 6 is interposed between both or either of the two side portions 5b, 5b (both in the illustrated embodiment) and the wall surface 1a facing the side portion 5b, so that the installation path 5a formed by the protective cover 5 is located away from the wall surface 1a. Therefore, by positioning the spacer 6 away from the intersection line 1c of the inner corner region where the two inner corner region virtual surfaces 1b, 1b, each containing the two wall surfaces 1a, 1a, intersect, the spacer 6, in addition to the protective cover 5, avoids interference with, for example, an obstacle 1d formed at the inner corner region intersection line 1c.

[0025] Specifically, the protective cover 5 consists of a straight protective cover 501 that extends linearly along the inner corner region 1. However, the protective cover 5 may also be an auxiliary protective cover connecting the straight protective covers 501, 501 together, or an auxiliary protective cover capable of accommodating the bending and branching points of the wiring and piping material 2 that bends or branches along at least one of the two wall surfaces 1a, 1a, or an auxiliary protective cover capable of accommodating the bending and branching points of the wiring and piping material 2 that bends or branches from at least one of the two wall surfaces 1a, 1a toward the back of the wall.

[0026] The straight protective cover 501 includes a first side portion 5x as the side portion 5b, a first base 701 as the base 7, and a first cover 801 as the cover 8. The first base 701 has two side walls 7a, 7a and a connecting portion 7b. The first base 701 (base 7) is fixed to the wall surface 1a by fasteners 9 such as screws that are screwed or driven into the wall surface 1a through its side wall 7a. When a spacer 6 is interposed between the side wall 7a (side portion 5b) and the side wall 7a (side portion 5b), the fasteners 9 penetrate the spacer 6 in addition to the side wall 7a, and the spacer 6 is also fixed to the wall surface 1a together with the side wall 7a (and thus the first base 701). However, the first base 701 may be fixed to the spacer 6 after the spacer 6 has been fixed to the wall surface 1a, or the first base 701 may be fixed to the wall surface 1a using fasteners 9 that penetrate the spacer 6. Alternatively, the first base 701 and the spacer 6 may be fixed by adhesive or bonding without using fasteners 9.

[0027] Furthermore, the first base 701 has holding portions 7c, 7c that protrude from each of its side walls 7a, 7a toward the installation path 5a, and these holding portions 7c, 7c hold the wiring and piping material 2 by sandwiching it between them.

[0028] The first lid 801 (lid 8) is plate-shaped and formed in a curved shape to surround the installation path 5a. The first lid 801 has ends 8a that extend to overlap the end faces of the side walls 7a of the first base 701, and the side portion 5b is formed by the side walls 7a of the first base 701 and the ends 8a of the first lid 801. The first lid 801 also has fitting protrusions 8b that protrude inward near both ends. The first base 701 has fitting recesses 7d that are surrounded by a holding portion 7c and a side wall 7a. The first lid 801 is assembled to the first base 701 by the fitting protrusions 8b fitting into the fitting recesses 7d. In addition, an insulating material 8c is attached to the back surface of the first lid 801 so as to span both fitting protrusions 8b, 8b.

[0029] The spacer 6 is formed in a strip shape and is positioned along the side wall 7a (side portion 5b). The top surface of the spacer 6 is provided with a straight alignment portion 6x for the protective cover, which serves as the alignment portion 6b. The spacer 6 is a straight spacer 601 that extends in a straight line, and the alignment portion 6b (more specifically, the straight alignment portion 6x for the protective cover) consists of a projection that is continuous in the longitudinal direction of the spacer 6 (more specifically, the straight spacer 601). The projection that forms the alignment portion 6b engages with a recess 7e (more specifically, a groove) formed in the side wall 7a (side portion 5b) of the base 7 (more specifically, the first base 701), thereby aligning the spacer 6 with the side portion 5b of the protective cover 5 (and consequently, the protective cover 5). In detail, the alignment portion 6b is formed of a soft material (for example, soft rubber or a soft resin such as soft polyvinyl chloride resin). More specifically, the alignment portion 6b consists of a hard core 6c and a soft material covering the core 6c. When this alignment portion 6b engages with the recess 7e in the side wall 7a, the soft material is compressed, causing friction in the direction of removal of the alignment portion 6b. This makes it difficult for the alignment portion 6b to come out of the recess 7e, and as a result, the spacer 6 is less likely to come off the base 7 (and consequently the protective cover 5). For example, when the base 7 is lifted, the spacer 6 will not fall off.

[0030] Furthermore, the spacer 6 has a groove 6d on its top surface that is continuous in the longitudinal direction of the spacer 6, and it can be cut at the portion of this groove 6d. Figure 7 shows an example in which the spacer 6 is interposed between one of the two side portions 5b, 5b and the wall surface 1a facing that side portion 5b.

[0031] Next, the effects of the protective cover device 3 and the installation structure 4 for the protective cover 5 shown in this first embodiment will be explained. With this protective cover device 3 and the installation structure 4 for the protective cover 5, in the inner corner area 1, the protective cover 5 is separated from the wall surface 1a by the interposition of a spacer 6 between the side portion 5b of the protective cover 5 and the wall surface 1a forming the inner corner area 1. Because the protective cover 5 is separated from the wall surface 1a, even if there is an obstacle 1d at the corner of the inner corner area 1 (i.e., the intersection line 1c of the inner corner area), the protective cover 5 can avoid interference with the obstacle 1d.

[0032] Furthermore, the width 6a of the spacer 6 is shorter than the distance 5f from the outer edge 5c of the side portion 5b in which the spacer 6 is interposed to the side intersection line 5e where the two virtual side surfaces 5d, 5d, which include the bottom surfaces of each side portion 5b, 5b, intersect, so that the spacer 6 can also avoid interference with the obstacle 1d. In addition, when the spacer 6 is aligned with the side portion 5b, it is separated from the corner intersection line 1c where the two virtual corner area surfaces 1b, 1b, which include the two wall surfaces 1a, 1a, intersect, so that the spacer 6 can also avoid interference with the obstacle 1d.

[0033] In other words, by providing such a spacer 6 to the protective cover 5 as needed, interference with the obstacle 1d at the corner of the inner corner area 1 (i.e., the intersection line 1c of the inner corner area) can be accurately avoided.

[0034] Furthermore, the spacer 6 is provided with a groove 6d, and by cutting the spacer 6 at the portion of this groove 6d, the width 6a of the spacer 6 can be reduced, thereby reliably avoiding interference with the obstacle 1d.

[0035] Figures 8 to 12 show a second embodiment of the present invention. In this second embodiment, the protective cover device 3 is a protective cover with an attached protective cover, where the protective cover 5 comprises a straight protective cover 501 and an attached protective cover 502. However, the basic configuration is the same as in the first embodiment, and similar parts are denoted by the same reference numerals below, while the differences will be mainly described.

[0036] The straight protective cover 501 has a first side portion 5x that constitutes the side portion 5b and extends linearly along the inner corner region 1. More specifically, the straight protective cover 501 has the same cross-sectional shape as the straight protective cover 501 as the protective cover 5 shown in the first embodiment, and comprises a first base 701 that constitutes the base 7 and a first cover 801 that constitutes the cover 8.

[0037] The attached protective cover 502 has a second side portion 5y that constitutes the side portion 5b, and also has a connection port 5g to which the straight protective cover 501 can be connected. In the illustrated embodiment, the attached protective cover 502 has two connection ports 5g, one on each side, so as to connect the two straight protective covers 501, 501. The two straight protective covers 501, 501 are located in the same straight line via this attached protective cover 502, and these straight protective covers 501, 501 extend in a straight line along the inner corner region 1.

[0038] Furthermore, the attached protective cover 502 is formed so that both of the second sides 5y, 5y are short and do not reach the side intersection line 5e where the two side virtual surfaces 5d, 5d, each including the bottom surface of each of the second sides 5y, 5y, intersect. A spacer 6 is interposed between both or either one (both in the illustrated embodiment) of the two second sides 5y, 5y of the attached protective cover 502 and the wall surface 1a facing the second side 5y, so that the two second sides 5y, 5y (more specifically, the two side walls 7a, 7a of the second base 702 described later) can be fixed to the two wall surfaces 1a, 1a.

[0039] In detail, the attached protective cover 502 comprises a second base 702 that constitutes the base 7 and a second cover 802 that constitutes the cover 8. The second base 702 has side walls 7a that constitute the second side portion 5y (more specifically, two side walls 7a, 7a and a connecting portion 7b that connects these two side walls 7a, 7a). This connecting portion 7b of the second base 702 connects both side walls 7a, 7a (both second side portions 5y, 5y) on the side closer to the side intersection line 5e and is positioned set back (away from) the side intersection line 5e. In the illustrated embodiment, the connecting portion 7b of the second base 702 is formed at an inclination with respect to both side walls 7a, 7a (both second side portions 5y, 5y). Furthermore, the second base 702 is formed such that the engaging portion 7f that engages with the first base 701 of the straight protective cover 501 protrudes on both sides (in the illustrated embodiment, the two side walls 7a, and the two portions where 7a and the connecting portion 7b are connected). Through this engagement, the attached protective cover 502 (specifically, the second base 702) is aligned with the straight protective cover 501 (specifically, the first base 701).

[0040] The second cover 802 is plate-shaped and curved to surround the installation path 5a. The second cover 802 has fitting protrusions 8b that protrude inward at both ends. The second base 702 has fitting recesses 7d, and the second cover 802 is assembled to the second base 702 by fitting the fitting protrusions 8b into the fitting recesses 7d. Furthermore, both sides of the second cover 802 along the installation path 5a are connection openings 5g, and these connection openings 5g are formed to be large enough to overlap the first cover 801 of the straight protective cover 501.

[0041] Spacer 6 is a continuous spacer positioned across the connected straight protective cover 501 and the attached protective cover 502. Spacer 6 is equipped with an alignment portion 6b that aligns with the side portion 5b on which the spacer 6 is interposed. The alignment portion 6b includes an alignment portion 6x for the straight protective cover that can align with the first side portion 5x of the straight protective cover 501, and an alignment portion 6y for the attached protective cover that can align with the second side portion 5y of the attached protective cover 502.

[0042] In detail, the spacer 6 is a straight spacer 601 having a cross-sectional shape similar to the spacer 6 shown in the first embodiment, and this straight spacer 601 is extended as is to also serve as an auxiliary spacer for the auxiliary protective cover. Therefore, the alignment portion 6b consists of an alignment portion 6x for the straight protective cover and an alignment portion 6y for the auxiliary protective cover, which are formed continuously in the longitudinal direction of the spacer 6 (more specifically, the straight spacer 601). These alignment portions 6x and 6y consist of protrusions, and the alignment portion 6x for the straight protective cover engages with a recess 7e (more specifically, a groove) formed in the side wall 7a (first side portion 5x) of the first base 701 of the straight protective cover 501, thereby aligning the spacer 6 with the first side portion 5x of the straight protective cover 501 (and consequently, the straight protective cover 501). Furthermore, the alignment portion 6y for the attached protective cover engages with a recess 7e (more specifically, a groove) formed in the side wall 7a (second side portion 5y) of the second base 702 of the attached protective cover 502, thereby aligning the spacer 6 with the second side portion 5y of the attached protective cover 502 (and consequently, the attached protective cover 502).

[0043] The effects and advantages of this second embodiment are the same as those of the first embodiment, except that the protective cover 5 comprises a straight protective cover 501 and an attached protective cover 502, and the spacer 6 is a continuous spacer that spans the straight protective cover 501 (two straight protective covers 501, 501 in the illustrated embodiment) and the attached protective cover 502.

[0044] Furthermore, the straight protective covers 501, 501 and the attached protective cover 502 are arranged in a straight line along the inner corner area 1, and these straight protective covers 501, 501 and the attached protective cover 502 can be placed at any position along the inner corner area 1.

[0045] Figures 13 to 20 show a third embodiment of the present invention. This embodiment differs from the second embodiment in that the spacer 6 is provided separately for the straight protective cover 501 and the attached protective cover 502, but the other basic configurations are the same. Below, the same parts are denoted by the same reference numerals, and the differences will be mainly described.

[0046] The straight protective cover 501 has a first side portion 5x that constitutes the side portion 5b and extends linearly along the inner corner region 1. More specifically, the straight protective cover 501 has the same cross-sectional shape as the straight protective cover 501 shown in the second embodiment (and by extension, the straight protective cover 501 as the protective cover 5 shown in the first embodiment), and similarly comprises a first base 701 that constitutes the base 7 and a first cover 801 that constitutes the cover 8.

[0047] The attached protective cover 502 has a second side portion 5y that constitutes the side portion 5b, and a connection port 5g to which the straight protective cover 501 can be connected. In detail, the attached protective cover 502 accommodates the bending or branching points (bending points or branching points) of the wiring / piping material 2 that bends or branches toward at least one of the two wall surfaces 1a, 1a. In the illustrated embodiment, the attached protective cover 502 has one of the connection ports 5g and accommodates the bending points of the wiring / piping material 2 that bends toward at least one of the two wall surfaces 1a, 1a. Here, the attached protective cover 502 (more specifically, the second base 702 described later) has a through hole 7g through which the wiring / piping material 2 passes, and similarly, the wall surface 1a has a wall hole 1e through which the wiring / piping material 2 passes.

[0048] Furthermore, the attached protective cover 502 is formed so that both of the second side portions 5y, 5y are short, without reaching the side intersection line 5e where the two side virtual surfaces 5d, 5d, each including the bottom surface of each of the second side portions 5y, 5y, intersect. A spacer 6 (more specifically, an attached spacer 602 described later) is interposed between both or either of the two second side portions 5y, 5y (in the illustrated embodiment, one) of the attached protective cover 502 and the wall surface 1a facing the second side portion 5y, so that the two second side portions 5y, 5y (more specifically, the two side walls 7a, 7a of the second base 702 described later) can be fixed to the two wall surfaces 1a, 1a.

[0049] In detail, the attached protective cover 502 comprises a second base 702 that constitutes the base 7 and a second cover 802 that constitutes the cover 8. The second base 702 has side walls 7a that constitute the second side portion 5y (more specifically, two side walls 7a, 7a and a connecting portion 7b that connects these two side walls 7a, 7a). This connecting portion 7b of the second base 702 connects both side walls 7a, 7a (both second side portions 5y, 5y) on the side closer to the side intersection line 5e and is positioned set back (away from) the side intersection line 5e. In the illustrated embodiment, the connecting portion 7b of the second base 702 is formed at an inclination with respect to both side walls 7a, 7a (both second side portions 5y, 5y). Furthermore, the second base 702 is formed such that the engaging portion 7f that engages with the first base 701 of the straight protective cover 501 protrudes to one side (in the illustrated embodiment, the two side walls 7a, protruding at two locations where 7a and the connecting portion 7b are connected). Through this engagement, the attached protective cover 502 (specifically, the second base 702) is aligned with the straight protective cover 501 (specifically, the first base 701).

[0050] The second cover 802 is plate-shaped and curved to surround the installation path 5a. The second cover 802 has fitting protrusions 8b that protrude inward at both ends. The second base 702 has fitting recesses 7d, and the second cover 802 is assembled to the second base 702 by fitting the fitting protrusions 8b into the fitting recesses 7d. At this time, the second cover 802 does not cover the entire second base 702, and a part of the second base 702 is exposed from the second cover 802 (see Figure 15). In addition, one side of the second cover 802 that is along the installation path 5a becomes the connection port 5g, and this connection port 5g covers the first cover 801 of the straight protective cover 501.

[0051] The spacer 6 comprises a linear spacer 601 extending in a straight line for the linear protective cover 501, and an auxiliary spacer 602 for the auxiliary protective cover 502, which is separate from the linear spacer 601. Here, the linear spacer 601 includes an alignment portion 6x for the linear protective cover that aligns with the first side portion 5x in which the linear spacer 601 is interposed. In detail, the alignment portion 6x for the linear protective cover consists of a projection continuous in the longitudinal direction of the linear spacer 601, and the alignment portion 6x for the linear protective cover engages with a recess 7e (more specifically, a groove) formed in the side wall 7a (first side portion 5x) of the first base 701 of the linear protective cover 501, thereby aligning the linear spacer 601 with the first side portion 5x of the linear protective cover 501 (and consequently, the linear protective cover 501).

[0052] The attached spacer 602 has a substantially semicircular notched hole 6e that aligns with a through hole 7g formed in the second base 702 of the attached protective cover 502. The attached spacer 602 also includes an alignment portion 6y for the attached protective cover that aligns with the second side portion 5y in which the attached spacer 602 is interposed. In detail, the alignment portion 6y for the attached protective cover consists of a columnar projection, and the attached spacer 602 is aligned with the second side portion 5y of the attached protective cover 502 (and consequently with the attached protective cover 502) by engaging with a recess 7e (more specifically, a hole) formed in the side wall 7a (second side portion 5y) of the second base 702 of the attached protective cover 502.

[0053] Furthermore, the attached spacer 602 has an engaging portion 6f that engages with the straight spacer 601, and this engagement aligns the attached spacer 602 with respect to the straight spacer 601. In the illustrated embodiment, the engaging portion 6f is formed to protrude so as to abut against the outer surface of the straight spacer 601, but the location of the abutment is not particularly limited.

[0054] The effects and advantages of this third embodiment are the same as those of the second embodiment, except that the spacer 6 is divided into a straight spacer 601 for the straight protective cover 501 and an auxiliary spacer 602 for the auxiliary protective cover 502.

[0055] Furthermore, the second base 702 of the attached protective cover 502 has a through hole 7g, and the attached protective cover 502 (specifically the second base 702) can be placed in the inner corner area 1 by aligning this through hole 7g with the wall hole 1e (or the notched hole 6e of the attached spacer 602). Subsequently, the straight protective cover 501 (specifically the first base 701) can be placed next to the attached protective cover 502 (second base 702).

[0056] Figures 21 to 24 show a fourth embodiment of the present invention. This embodiment differs from the second embodiment in that the attached protective cover 502 has an additional connection port 5h in addition to the two connection ports 5g, 5g, and the spacer 6 is provided separately for the straight protective cover 501 and the attached protective cover 502. Otherwise, it is the same, and the same parts are denoted by the same reference numerals below, with the differences being the main focus of the description.

[0057] The attached protective cover 502 is formed in a T-shape, with two connection ports 5g, 5g provided at opposing positions, corresponding to the connection ports in the second embodiment, and another connection port 5h provided on the side perpendicular to these two connection ports 5g, 5g. Thus, straight protective covers 501, 501 extending linearly along the inner corner region 1 formed by the two wall surfaces 1a, 1a are connected to the two connection ports 5g, 5g. Another straight protective cover 503 extending linearly along one of the two wall surfaces 1a, 1a so as to move away from the inner corner region 1 is connected to the other connection port 5h.

[0058] The accessory spacer 602 for the accessory protective cover 502 consists of one T-shaped accessory spacer 603 and the other straight accessory spacer 604. The T-shaped accessory spacer 603 is positioned on one wall surface 1a between the two connection ports 5g, 5g and the other connection port 5h, and the straight accessory spacer 604 is positioned on the other wall surface 1a between the two connection ports 5g, 5g.

[0059] Furthermore, similar to the spacer 6 shown in the third embodiment, the attached spacer 602 is provided with an engaging portion 6f that aligns with the straight spacer 601. In the illustrated embodiment, this engaging portion 6f is formed to protrude so as to abut against the outer surface of the straight spacer 601, but the location of the abutment is not particularly limited.

[0060] The effects and advantages of this fourth embodiment are the same as those of the second embodiment, except that the spacer 6 is divided into a straight spacer 601 for the straight protective cover 501 and an auxiliary spacer 602 for the auxiliary protective cover 502, and furthermore, the auxiliary spacer 602 consists of a T-shaped auxiliary spacer 603 and a straight auxiliary spacer 604. It should be noted that the present invention is not limited to the embodiments described above, and various other modifications are possible. For example, the straight protective cover 501 consists of a first base 701 and a first lid 801, both of which are formed longitudinally. However, as shown in Figure 25, only the first lid 801 may be formed longitudinally, and the first base 701 may be formed shorter, with multiple first bases 701 provided and these first bases 701, 701 arranged at intervals. Similarly, the spacer 6 placed on the straight protective cover 501 does not have to be a straight spacer 601 that extends in a straight line. It may be formed shorter, with multiple spacers 6, 6 provided and these spacers 6, 6 arranged at intervals.

[0061] Furthermore, the straight protective cover 501 and the attached protective cover 502 consist of a base 7 (specifically, a first base 701 and a second base 702) and a lid 8 (specifically, a first lid 801 and a second lid 802). These may be separate components that are not separable, or they may be rotatable by a hinge, or they may be formed as a single cylindrical shape.

[0062] Furthermore, in the second embodiment, the spacer 6 consists of a continuous spacer that spans the straight protective cover 501 and the attached protective cover 502. However, as shown in Figure 26, it may be divided into a straight spacer (not shown) for the straight protective cover 501 and an attached spacer 602 for the attached protective cover 502.

[0063] Furthermore, in the third embodiment, the spacer 6 is divided into a straight spacer 601 and an attached spacer 602, but as shown in Figure 27, these may be formed as a single straight continuous spacer.

[0064] Furthermore, if the protective cover 5 comprises a straight protective cover 501 and an attached protective cover 502, and the spacer 6 is a continuous spacer, the cross-sectional shape of the spacer 6 does not necessarily have to be constant, and in the alignment portion 6b, the alignment portion 6x for the straight protective cover and the alignment portion 6y for the attached protective cover do not necessarily have to be formed continuously in the longitudinal direction of the spacer 6.

[0065] Furthermore, while the protective cover 5 (such as the straight protective cover 501 or the attached protective cover 502) is intended to house and protect the wiring and piping material 2, if the wiring and piping material 2 bends or branches, the bends and branching points of the wiring and piping material 2 housed and protected by the attached protective cover 502 include not only the points where the wiring and piping material 2 directly bends or branches, but also the points where it bends or branches due to connectors or fittings.

[0066] Furthermore, in the protective cover 5, the connecting portion 7b that connects the side walls 7a, 7a (side portions 5b, 5b) is formed at an angle (i.e., in a diagonal cut shape), but it may also be formed in an arc shape. Also, depending on the size of the obstacle 1d, this connecting portion 7b may not be provided, and the side walls 7a, 7a (side portions 5b, 5b) may extend directly to the side intersection line 5e.

[0067] Furthermore, spacers 6 may be used in a manner where multiple spacers are stacked on top of each other, rather than using just one spacer per location. [Explanation of Symbols]
