  1 to 5 show a first example of a wiring / piping material protective cover according to the present invention. A bent portion protective cover 10 as a wiring / piping material protective cover of this example is composed of a base 20 shown in FIGS. 1 to 3 and a lid body 40 shown in FIGS. 4 and 5. As shown in FIG. 4, by mounting the lid 40 on the base 20, a housing space S for wiring / piping material H is formed inside, and the wiring / piping material H is accommodated and protected in this housing space S. It is. Further, the bent portion protective cover 10 of this example is adapted to correspond to different bending angles of the bent portion of the wiring / pipe material H depending on whether it is used as it is without being cut or is used after being cut. When used without cutting, it can correspond to the first bending angle, specifically 45 ° in this example. When used after cutting, the second bending angle is smaller than the first bending angle. The angle, specifically, 30 ° in this example can be dealt with.

  First, the base 20 is fixed to the construction surface by a double-sided adhesive tape, an adhesive, or the like, and includes a bottom plate portion 23 formed in a flat plate shape and a pair of second plates erected at the center portion of the bottom plate portion 23. The first standing wall portion 24 and the second standing wall portion 25 erected on the outside of each first standing wall portion 24 are provided. And the latching protrusion 26 which protrudes toward the outer side is arrange | positioned in the upper part of the 2nd standing wall part 25 at appropriate intervals. Further, the base 20 is provided with a screw hole 27 so that it can be fixed to the construction surface by a set screw.

  The base 20 is provided with a cutting portion 15 (hereinafter referred to as a “base cutting portion 30”) over the entire width, and the base 20 has a first base with the base cutting portion 30 as a boundary. It is divided into a base part 21 and a second base part 22. The bent portion protective cover 10 of this example accommodates and protects the 45 ° bent portion of the wiring / pipe material H. Of the 45 °, the first base portion 21 is 30 ° worth. The second base portion 22 is configured to bear the remaining 15 °.

  The base cutting part 30 is separated into the first base part 21 and the second base part 22 by cutting, and has a structure having a cutting guide that serves as a guide for a cutting tool such as a saw or a knife. ing. In this example, the cutting guide is constituted by a groove 31 and a slit 32 provided in the bottom plate portion 23. Moreover, in the 1st standing wall part 24 and the 2nd standing wall part 25, the site | part corresponding to the base cutting part 30 is abbreviate | omitted, and it divides | segments into the 1st base part 21 side and the 2nd base part 22 side. ing.

  As shown in FIG. 3B, the groove 31 constituting the cutting guide is formed in a substantially V shape having an inclined surface that is inclined so that the bottom surface becomes deeper toward the first base portion 21 side. Yes. Further, the depth of the groove 31 is substantially half the thickness of the bottom plate portion. On the other hand, the slit 32 constituting the cutting guide penetrates the bottom plate portion 23 of the base 20 as shown in FIG. 3C, and the bottom plate of the base 20 as shown in FIG. The portion 23 occupies substantially half of the entire width.

  The base 20 is provided with a center index 28 serving as a centerline index at the center in the width direction. A center index 28 is also provided at a portion on the first base portion 21 side adjacent to the base cutting portion 30. Here, the reason why the center indicator 28 is provided on the first base portion 21 side and the center indicator 28 is not provided on the second base portion 22 side is that the base cutting portion 30 is cut by cutting the first base portion 21. And the second base part 22, the first base part 21 is used, and the second base part 22 is not used and discarded. Is not necessary. In this example, the center index 28 is constituted by a fine groove as shown in FIG.

  Next, the lid body 40 is suspended from the top plate portion 43 formed in a gentle arc shape, a pair of protrusions 44 protruding from the central portion of the top plate portion 43, and the outside of each protrusion 44. The locking piece 45 is provided. In addition, on the back surface of the lid 40, a portion that is separated by a predetermined distance from the position corresponding to the base cutting part 30 of the base 20 when mounted on the base 20 as described later extends over the entire width. A cutting part 15 (hereinafter referred to as “lid cutting part 50”) is provided. In addition, if this positional relationship is seen from the base 20, the base cutting part 30 is formed a predetermined distance deeper than the lid cutting part 50 of the lid 40. Here, the predetermined distance corresponds to a length from an end portion of the thin portion 46 described later. The lid body 40 is divided into a first lid body part 41 and a second lid body part 42 with the lid body cutting part 50 as a boundary. The bent portion protective cover 10 in this example accommodates and protects the 45 ° bent portion of the wiring / pipe material H. Of the 45 °, the first lid portion 41 is 30 ° worth. The second lid 42 is configured to carry the remaining 15 °.

  The lid cutting part 50 is separated into the first lid part 41 and the second lid part 42 by cutting, and has a structure having a cutting guide for guiding a cutting tool such as a saw or a knife. ing. And in this example, as shown in FIG.5 (c), the cutting | disconnection guide is the groove | channel 51 provided in the back surface of the top-plate part 43, and is comprised by the shallow groove | channel about 1/4 of thickness.

  In addition, both end portions of the lid 40 are thin portions 46 that are reduced in thickness by a predetermined length. Further, a portion of the lid 40 adjacent to the lid cutting portion 50 and on the first lid 41 side is a thin portion 46 having a thickness reduced by a predetermined length.

  When the lid 40 is attached to the base 20, the bent portion protective cover 10 configured as described above forms a collecting space S for accommodating the wiring / piping material H, as shown in FIG. 6. Here, in this example, a large accommodation space S1 is formed between the pair of first standing wall portions 24, and a thick wiring / pipe material H such as a power line H1 or a conduit H3 can be accommodated in the accommodation space S1. . Further, a small accommodation space S2 is formed between the first standing wall portion 24 and the second standing wall portion 25, and a thin wiring / pipe material H such as the signal line H2 can be accommodated in the accommodation space S2.

  In order to attach the lid 40 to the base 20, the lid 40 is pressed against the base 20 from above, and the latching pieces 45 of the lid 40 are latched to the latching protrusions 26 of the base 20. 40 may be fitted to the base 20. As a result, the lid 40 can be attached to the base 20 without being easily removed. Further, in the state where the lid body 40 is mounted on the base 20, the lid body 40 is supported by the first standing wall portion 24 and the second standing wall portion 25, and thereby, the lid body 40 is prevented from being crushed. The structure withstands stress applied from above. Further, the protrusion 44 on the back surface of the lid body 40 is in contact with the inside of the first standing wall portion 24. Thereby, when the stress from the upper part is added to the cover body 40, it is prevented that the 1st standing wall part 24 falls down inside and the accommodation space S is crushed. In particular, the bent portion protective cover 10 of this example is mainly used to protect the wiring / piping material H when the wiring / piping material H is disposed on the floor surface. With the above-described structure, even if the lid 40 is stepped on with a foot, the structure can withstand enough.

  By the way, when the cover 40 is attached to the base 20 to form the bent portion protective cover 10 as a whole, the straight portions of the wiring / pipe material H are accommodated and protected at both ends as shown in FIG. Since the straight protective cover 60 is connected, the bent portion protective cover 10 is configured to include the connection ports 11 of the straight protective cover 60 at both ends thereof. In this example, the connection port 11 includes a contact portion 12 that contacts the end portion of the straight protective cover 60 and a covering portion 13 that covers the end portion of the straight protective cover 60. Further, in this example, the connection port 11 is configured by the end of the base 20 and the end of the lid 40.

  Specifically, as shown in FIG. 1, both ends of the base 20 form a contact portion 12 that is a part of the connection port 11, and as shown in FIG. 4, the thin portions at both ends of the lid 40 are formed. The cover portion 13 which is a part of the connection port 11 is configured by the portion 46. Further, when the base cutting part 30 of the base 20 is cut, the base cutting part 30 constitutes the end of the base 20 and when the lid cutting part 50 of the lid 40 is cut. Since the lid cutting part 30 constitutes an end of the lid 40, the contact part 12 can be formed also by the base cutting part 30, and the thin part 46 adjacent to the lid cutting part 50 is used. Also, the covering portion 13 can be formed. In addition, the thin part 46 of the site | part adjacent to the cover cutting part 50 of the cover body 40 is for forming the connection port 11 of the same shape as the connection port of the straight-shaped protective cover 60, and the connection port formation part 14 is used. Can be understood as

  Next, based on FIG. 7, the usage example of the protection cover 10 for bending parts of this example is demonstrated. In addition, in FIG. 7, the aspect which accommodates and protects the bending part of 45 degrees of bending angles of the wiring and piping material H is shown, without using the protection cover 10 for bending parts.

  The bent portion protective cover 10 has a straight protective cover 60 connected to both ends thereof. Here, as shown in FIG. 7A, the straight protective cover 60 includes a base 61 fixed to the construction surface and a lid 62 attached to the base 61, and has a long shape. It is formed and used by cutting with appropriate dimensions so that the end surfaces of the base 61 and the lid 62 are aligned. The straight protective cover 60 is substantially the same as the bent portion protective cover 10 except that the base 61 and the lid 62 are not provided with a cutting portion and the lid 62 is not provided with a thin portion 64. It has the same cross-sectional shape and is fitted to the base 61 by pressing a lid 62 from above.

  As shown in FIG. 7B, first, the base 61 of the straight protective cover 60 and the base 20 of the bent portion protective cover 10 are fixed to the construction surface. At the time of fixing, the ends of the base 61 of the straight protective cover 60 are in contact with both ends of the base 20 of the bent portion protective cover 10. Then, after the wiring / pipe material H is disposed on each of the bases 20 and 61, the lid body 62 is attached to the base 61 of the straight protective cover 60. Next, as shown in FIG. 7C, the lid body 40 is attached to the base 20 of the bent portion protective cover 10. Then, as shown in FIG. 8, the end of the lid 62 of the straight protective cover 60 is covered by the covering portion 13 of the lid 40 of the bent portion protective cover 10, so that the bent portion protective cover is formed. 10 and the straight protective cover 60 are connected, and thus the protection of the wiring and piping material H by the protective covers 10 and 60 is completed.

  Next, FIG. 9 shows a state in which the bent portion of the wiring / pipe material H with a bending angle of 30 ° is accommodated and protected using the cut bent portion protective cover 10. In this example, the base 20 is cut at the base cutting part 30 and separated into a first base part 21 and a second base part 22, and then the second base part 22 is discarded and the first base part is discarded. The base part 21 is used, and the lid body 40 is cut by the lid body cutting part 50 and separated into the first lid body part 41 and the second lid body part 42, and then the second lid body part 42 is discarded. Thus, the first lid portion 41 is used. And about the base 20, the edge part of the base cutting part 30 becomes the contact part 12 contact | abutted to the edge part of the straight-shaped protective cover 60, and about the cover body 40, the thin part adjacent to the cover body cutting part 50 Reference numeral 64 denotes a covering portion 13 that covers the end portion of the straight protective cover 60. Therefore, the connection port 11 at the end of the cut side has the same shape as the connection port 11 at the other end or the connection port 11 at the end when used without cutting, and is connected to the end of the straight protective cover 60. It can be connected accurately.

Next, the operation of the bent portion protective cover 10 of this example will be described.
The bent portion protective cover 10 is provided with a base cutting portion 30 and a lid cutting portion 50. By cutting these cut portions 15, the bent portion protection corresponding to different bending angles of the wiring / pipe material H is provided. A cover can be formed. And since the connection port formation part 14 for forming the connection port 11 which can connect the straight protective cover 60 to the part adjacent to the cover body cutting part 50 is provided, it is cut | disconnected with a simple structure. The straight protective cover 60 is connected to both ends of the bent portion protective cover 10 immediately and simply by cutting with the cutting portion 15 without attaching a dedicated connecting member or the like to the end portion. Can do.

  Further, the contact portion 12 that contacts the end of the straight protective cover 60 can prevent further insertion of the straight protective cover 60, and the straight protective cover 60 and the bent portion protective cover 10 can be connected to each other. They can be accurately positioned with respect to each other. Further, the end portion of the straight protective cover 60 can be concealed by the covering portion 13 covering the end portion of the straight protective cover 60, and dust and dust intrusion from the joint portion with the straight protective cover 60 is suppressed. can do.

  By the way, since the base 20 is fixed to the construction surface and it is not necessary to ensure that much rigidity, the cutting guide of the base cutting part 30 is guided by the deep groove 31 and the slit 32 as described above. Can be formed. Further, the bottom plate portion 23 on which the cutting guide is provided has a flat plate shape. Therefore, it is possible to cut the base cutting unit 30 by folding it by hand without using the cutting tool. Here, the cutting guide groove 31 is a substantially V-shaped groove 31 having a bottom surface inclined toward the first base portion 21 side, so that the base cutting portion 30 can be folded by hand. When cut, as shown in FIG. 10, the breakage proceeds toward the first base portion 21 side. Therefore, the first base portion 21 on the side where the end surface is used as the contact portion 12 is unlikely to generate a burr that protrudes from the end surface. As described above, assuming that the base cutting unit 30 is cut by folding by hand, it is preferable to use the substantially V-shaped groove 31 inclined to the side to be used as the cutting guide as the cutting guide.

  On the other hand, since it is highly likely that a large external force, such as being stepped on with a foot, is applied to the lid 40, it is desired to ensure sufficient rigidity. Therefore, it is desirable that the lid cutting unit 50 has a structure that cannot be easily folded by hand. For this reason, as in this example, it is preferable to configure the cutting guide by the shallow groove 51 instead of the deep groove or slit.

  In addition, in the cutting part 15 of the base cutting part 30 or the lid cutting part 50, the cutting guide is not limited to a groove or a slit, but a so-called `` perforation '' in which circular or rectangular through holes are continuously provided at a predetermined interval, It is good also as the marking line formed by the very shallow groove | channel, or the line drawn by printing. In addition, the cutting guide is not limited to the cutting unit 15, and the cutting guide may be omitted, and the operator may cut the cutting unit 15 according to the target amount.

  Next, FIG. 11 shows a bent portion protective cover 10a as a wiring / piping material protective cover of the second example. In this second example, the base 20 has the same configuration as the base 20 of the first example, but the lid 40a has the following configuration.

  The lid 40a of the second example includes both the first lid part 41 side and the second lid part 42 side in the connection port forming part 14 between the first lid part 41 and the second lid part 42. Further, two cutting parts 50 such as a first lid part cutting part 53 and a second lid part cutting part 54 are provided. In this second example, the base cutting part 30 of the base 20 is cut to use the first base part 21, and the first lid part cutting part 53 of the lid 40a is cut to form the first lid. By using the portion 41, a bending angle of 30 ° can be handled. On the other hand, while using the 2nd base part 22 which cut | disconnected the base cutting part 30 of the base 20, and cut | disconnected the cutting part 54 for the 2nd cover part of the cover 40a, the 2nd cover part By using 42, it is possible to cope with a third bending angle such as 15 °.

  Next, FIG. 12 shows a bent portion protective cover 10b as a wiring / piping material protective cover of a third example. In this third example, a discard base 29 is provided between the first base 21 and the second base 22 for the base 20 b, and the first base of the discard base 29 is provided. Two cutting parts 30 such as a first base part cutting part 33 and a second base part cutting part 34 are provided on both the part 21 side and the second base part 22 side. In addition, with respect to the lid body 40 b, two connection port forming portions 14 are provided in both the part on the first lid part 41 side adjacent to the lid cutting part 50 and the part on the second lid part 42 side. In this third example, the first base part 21 is used by cutting the first base part cutting part 33 of the base 20b, and the first cover part 50 is cut by cutting the lid cutting part 50 of the lid 40b. By using the portion 41, a bending angle of 30 ° can be handled. Separately from the one corresponding to the bending angle of 30 °, the second base portion cutting portion 34 of the base 20 is cut to use the second base portion 22, and the first cutting is performed. By using the second lid part 42 separated from the lid part 41, a bending angle of 15 ° can be handled.

  As described above, the bending portion protective covers 10, 10a, and 10b of the present invention have been illustrated, but the present invention is not limited to the above-described examples, and appropriate modifications can be made without departing from the gist of the present invention.

  For example, although it is assumed that it corresponds to a bending angle of 45 ° without cutting, it may correspond to a bending angle different from this example, such as 90 ° or 60 ° without cutting. Moreover, when using it by cut | disconnecting, it is not restricted to correspond to 30 degrees and 15 degrees, What is necessary is just to set suitably as an angle smaller than the corresponding angle used in the state which is not cut | disconnected.

  Further, the bent portion protective cover 10 of each of the above embodiments is provided with one cutting portion 15 on each of the base 20 and the lid body 40 and can be cut into two, but is not limited thereto. Instead, it is possible to provide the cutting portions 15 at two or more locations so that the cutting portions 15 can be cut into three or more and can cope with more bending angles.

  In addition, the bent portion protective cover 10 of each of the above embodiments is formed by a two-part body of the base 20 and the lid body 40, but is not necessarily limited to this, and its end portion after cutting. If the connection port forming portion capable of accurately connecting the straight protective cover 60 can be formed, it does not hinder the formation of a single unit.

  By the way, the present invention is particularly effective in the case where the bending angle is less than 90 ° without cutting, as in this example. This is due to the following reason. That is, when the wiring / pipe material H is provided, it is frequently bent at 90 °, and the protective cover corresponding to the bending angle of 90 ° is assumed to be used frequently. Here, providing the cutting part 15 and the connection port forming part 14 with respect to the protective cover for 90 ° which is frequently used increases wasteful configuration, leading to a decrease in strength and unnecessary consumption of materials. Become. Therefore, the protective cover corresponding to the 90 ° bending angle, which is assumed to be used frequently, is dedicated to 90 °, while it corresponds to the bending angle of less than 90 °, which is assumed to be used relatively infrequently. This is because it is preferable to apply the present invention to a protective cover with excellent convenience that can cope with different bending angles depending on whether or not to cut.
