  The present invention provides a wiring material such as a cable arranged along a wall surface of a building, a floor surface, a peripheral wall surface of a box used as a wiring piping material or the like, a piping material such as a water supply hot water supply pipe or a refrigerant pipe for an air conditioner. It is attached to the wall penetration part that penetrates the through hole formed in the material, and is installed along the wiring material and piping material arrangement path, and a protective duct that houses and protects the wiring material and piping material is inserted inside The present invention relates to a decorative cover and a decorative cover device for a wall penetration portion.

  Conventionally, the various wiring materials and piping materials disposed between the indoor unit and the outdoor unit are disposed along the wall surface of the building, and are provided on the wall material partitioning the interior and the exterior. It is disposed through the through hole. The wiring and piping material are protected from the outside by attaching a long protective duct to the outside. The protective duct includes a straight protective duct having the same cross-section formed continuously, and a corrugated protective duct having an annular unevenness formed on the outer surface. Depending on the situation, it is appropriately selected and used. In the wall penetrating portion that penetrates the wall material, the protective duct is installed with its end portion inserted into the through hole of the wall material, or with its front end surface in contact with the wall surface. And in this wall penetration part, in order to maintain the external appearance by covering the part which protruded outside from the outer surface of the said protective duct in the through-hole of wall material, the decorative cover is attached. The decorative cover includes a decorative portion that is larger than the through hole of the wall material, and a receiving port into which an end portion of the protective duct is inserted.

  Here, a decorative cover used for the straight protective duct is disclosed in, for example, Japanese Patent Application Laid-Open No. 11-22866. FIG. 25 is a perspective view showing a decorative cover in a conventional wall penetrating portion. In FIG. 25, a through hole 53 formed in the wall material 51 of the wall material 51 and the wall material 52 orthogonal to each other in the building A refrigerant pipe P for an air conditioner passes therethrough, and a straight protective duct 31 that accommodates and protects the refrigerant pipe P is disposed along the wall surface 55 of the wall member 52. The front end surface of the straight protective duct 31 is in contact with the wall surface 54 of one wall member 51, and a part of the through hole 53 protrudes from the outer surface of the straight protective duct 31. For this reason, the decorative cover 61 for covering the entire wall penetrating portion and maintaining the appearance is attached perpendicularly to the straight protective duct 31. Here, the receiving port 62 into which the straight protective duct 31 is inserted in the decorative cover 61 does not cause a large gap between the outer surface of the straight protective duct 31 and deteriorate the appearance of the wall penetration portion. The straight protective duct 31 is formed in the same size and the same shape as the outer shape.

An engaging claw that enters the annular recess 43 of the corrugated protection duct 41 and engages with the receiving port 64 to prevent the corrugated protective duct 41 from being detached from the receiving port 64. 65 projects inward. This is because the corrugated protection duct 41 is flexible and can be expanded and contracted in the longitudinal direction, so that it may be detached by bending downward just by being inserted into the receiving port 64.

Japanese Patent Laid-Open No. 11-22866 JP-A-10-185243

  By the way, since the protection duct which accommodates and protects wiring and piping materials is normally arrange | positioned along the wall surface of a building, generally the straight-shaped protection duct 31 is used. However, there are cases where various protrusions are provided on the wall of the building, and a corrugated protective duct 41 that is freely bent is attached to the portion where these protrusions are provided to bypass the protrusions. Has been done.

  In this case, even if the end portion of the corrugated protective duct 41 is inserted into the decorative cover 61 for the straight protective duct 31 at the wall penetrating portion, the decorative cover 61 is inserted into the annular recess 43 of the corrugated protective duct 41. Since there is no engaging claw 65 or the like that enters and engages, the corrugated protective duct 41 may be detached from the decorative cover 61.

  Conversely, even if the straight protective duct 31 is to be inserted into the decorative cover 63 for the corrugated protective duct 41, the engaging claws 65 projecting inwardly toward the receiving port 64 of the decorative cover 63, etc. And could not be inserted into the receiving port 64.

  Furthermore, even if it can be inserted into the receiving port 64 of the decorative cover 63 for the corrugated protective duct 41 by reducing the outer dimension of the straight protective duct 31, the receiving port 64 and the straight protective duct 31 may be used. Since a considerable gap is generated between the outer surface and the outer surface, the appearance of this portion is significantly reduced. In addition, dust entered and accumulated in the gap.

  Since such a problem occurs, one decorative cover cannot be used for both the straight protective duct 31 and the corrugated protective duct 41 in the same arrangement route or the like. For this reason, two types of decorative covers were required to accommodate each protective duct. As a result, it was necessary to use them properly, the member cost was high, and parts management was complicated. In addition, when it becomes necessary to replace the direct protection duct 31 and the corrugated protection duct 41 later due to a change in the state of arrangement on the wall surface, the decorative cover must also be removed from the wall surface, etc. It was troublesome.

  Therefore, the present invention provides a decorative cover and a decorative cover device for a wall penetrating portion that can be used as both a straight protective duct and a corrugated protective duct, and can obtain a good appearance at the wall penetrating portion. The issue is to provide

The decorative cover of the wall penetration part of Claim 1 is installed along the arrangement | positioning path | route of wiring / piping material, and the straight cross-section in which the same cross section which accommodates and protects the said wiring / piping material was formed continuously. It is possible to insert either a duct or a corrugated protective duct that is installed along the wiring / piping material arrangement path and that has an outer surface that encloses and protects the wiring / piping material. And at least one receiving port, a decorative portion that covers a gap between the outer surface of the protective duct and the through hole of the wall material, and a fixing portion that is fixed to the wall through portion, and the receiving port projects inwardly. Te, it enters the annular recess of the wave with protective ducts, and protrusions for closing the gap between the the outer surface socket along the outer surface in proximity to the outer surface of the distal end surface is the straight protective duct Is provided. Here, a wall penetration part means the whole periphery of the through-hole drilled in the wall material. Moreover, the wall material includes a wall material such as an outer wall and a partition wall of a building, a peripheral wall of a box used for a floor material, a wiring piping material, and the like.

  The said decorative part is a part which covers the through-hole of wall material, and covers the whole said through-hole in the state contact | abutted to the wall surface in the wall penetration part, the floor surface, etc., or the separated state. The receptacle includes a part deeper than the opening, means the whole part into which the straight protective duct and the corrugated protective duct are inserted, and is provided integrally or separately in the decorative part. In general, only one receiving port is provided, but two or more receiving ports may be provided. A fixing portion for fixing the decorative cover to the wall surface or the like is provided as an attachment hole or the like in the decorative portion or the like, and is fixed by inserting a screw and screwing it on the wall surface or the like.

  Further, the protrusion provided inwardly projecting from the receiving port enters the annular recess when the corrugated protection duct is inserted, and after the insertion when the straight protection duct is inserted. A gap formed between the outer surface of the straight protective duct and the receiving port is closed along the outer surface of the straight protective duct. Even when the corrugated protection duct is inserted into the decorative cover, the protrusion enters the annular recess and closes the gap formed between the protrusion and the receiving port along the outer surface of the corrugated protection duct. Note that it is sufficient that the protruding portion enters the annular recess of the corrugated protection duct to the extent that the corrugated protective duct is prevented from being pulled out in the longitudinal direction from the opening of the decorative cover.

  Here, with regard to the dimensional relationship between the ridge portion of the receiving port and the outer surface of each protective duct, in the case of a straight protective duct, the front end surface of the ridge portion of the receiving port is substantially the same as the outer surface of the straight protective duct. In the case of a corrugated protective duct, the tip end surface of the ridge portion of the receiving port is located between the outer surface of the annular convex portion and the outer surface of the annular concave portion of the corrugated protective duct.

  Next, the protective duct inserted into the receiving port 3 of the decorative cover 1 will be described. First, as shown in FIG. 6, the straight protective duct 31 is formed in a rectangular frame shape having a constant cross-sectional shape along the longitudinal direction, and is elastic to the base 31 and the base 31 that can be fixed to a wall surface. It is formed by assembling a two-divided body with the cover 33 to be fitted into the. The base 32 is formed in a substantially U-shaped constant cross section that opens upward, and is fitted to a flange 38 (described later) of the cover 33 at the upper end of a side wall 35 standing on both the left and right sides of the substrate 34 at the bottom. A fitting groove 36 is formed. The cover 33 is formed in a cover shape in which a cover portion 37 covering the upper opening of the base 32 is gently curved upward, and is bent horizontally at both left and right end portions in the width direction to fit in the fitting groove 36 of the base 32. Are integrally provided with a flange 38. In addition, the board | substrate 34 of the said base 32 is equivalent to the contact part of a claim.

  The base 32 is formed in a state where the upper portions of the left and right side walls 35 are slightly warped outward at the time of molding. By forcibly pushing the cover 33 from above, the upper portions of the side walls 35 are moved to the inner side. The flange 38 of the cover 33 can be fitted into the fitting groove 36 by bending. Thereby, the cover 33 is elastically detachably attached to the base 32, and a stable straight protective duct 31 is obtained. The cover 33 can be used alone by being formed in a U-shaped cross section so as to be disposed on the wall surface.

  On the other hand, the corrugated protective duct 41 is formed in a substantially rectangular frame shape, and the annular convex portions 42 and the annular concave portions 43 are alternately arranged in the longitudinal direction, has flexibility, and is extensible in the longitudinal direction. It has become a thing. For this reason, it is provided in the bending part or detour part of the arrangement route. Further, the bottom portion of the corrugated protective duct 41 is not shown, but, for example, the slit portion described in Japanese Patent Laid-Open No. 10-68536 previously disclosed by the applicant of the present application is formed continuously in the longitudinal direction, or If necessary, it can be formed by using a tool such as a cutter, and the bottom surface portion can be expanded in the width direction at the cutting portion. Thereby, in a state where the wiring material and the piping material are arranged along the wall surface, the corrugated protection duct 41 is expanded on both sides at the cut portion, and the corrugated protection duct 41 is expanded to the wiring material and the piping material. Can be attached so as to cover from above.

  Next, a method for attaching the decorative cover of the present embodiment configured as described above to the wall penetrating portion will be described with reference to FIGS. In the present embodiment, an example in which the decorative cover 1 includes only the upper lid 11 is used, and an air conditioner refrigerant pipe is used as a wiring / piping material.

  In FIG. 7, a through hole 53 is formed in one wall member 51 at a corner where two wall members 51 and 52 of the building are orthogonal to each other, and along this wall surface 55 of the other wall member 52. The refrigerant pipe P for the air conditioner arranged through is penetrated. Here, the through-hole 53 is usually separated from the wall surface 55 of the other wall member 52 by an amount that avoids at least the cover portion of the piercing tool for drilling the hole from interfering with the other wall surface 55. Provided in position. Therefore, the refrigerant pipe P is disposed in the air separated from the wall surface 55 of the other wall member 52 by a predetermined distance. However, when the through hole 53 is formed in a square hole or the like with a tool such as a saw, the through hole 53 can be drilled while being in contact with the other wall surface 55. Can be disposed in contact with the wall surface 55.

  Now, it is assumed that the straight protective duct 31 is disposed along the wall surface 55 of the other wall member 52 in order to protect the refrigerant pipe P. Therefore, in the state where the refrigerant pipe P is disposed, first, the base 32 of the straight protective duct 31 is passed through the gap between the refrigerant pipe P and the wall surface 55, and the tip end surface of one wall member 51 is inserted. After coming into contact with the wall surface 54, in that state, a screw is inserted into a screw hole (not shown) provided in the substrate 34 of the base 32 and screwed to the other wall member 52. Next, by pushing the cover 33 from the upper opening side of the base 32, the flange 38 of the cover 33 is elastically fitted into the fitting groove 36 of the base 32. Thereby, the cover 33 is detachably attached to the base 32. In this state, a part of the through hole 53 provided in one wall member 51 generally protrudes outward from the straight protective duct 31 and is exposed to the wall surface. If the gap between the refrigerant pipe P and the wall surface 55 is extremely small and the base 32 cannot be inserted into the gap after the refrigerant pipe P is disposed, the base 32 is first attached to the other wall surface 55. After that, the refrigerant pipe P may be inserted into the base 32.

  Next, when the refrigerant pipe P and the straight protection duct 31 are arranged in this way, the end of the straight protection duct 31 is orthogonal to the other wall surface 55, and the longitudinal direction of the straight protection duct 31. The receptacle 13 of the top cover 11 of the decorative cover 1 is externally fitted to the straight protective duct 31 from the orthogonal direction, and the back side of the decorative portion 12 of the decorative cover 1 is brought into contact with the wall surface 54 of one wall member 51. . Next, the screw 56 is inserted into the fixing hole 15 of the decorative portion 12 and screwed to the wall material 51 to fix the decorative cover 1. As a result, the protruding portion of the through hole 53 provided in the wall material 51 is completely covered by the decorative portion 12 of the decorative cover 1 as shown in FIGS.

  And the protrusion part 16 is formed in the opening edge part of the receiving port 13 of the upper cover 11 of the said decorative cover 1, and the front end surface 16a of the said convex part 16 is in the state in which the decorative cover 1 was attached. Since it is formed along the outer surface of the straight protective duct 31, as shown in FIGS. 8 and 9, a gap formed between the receiving port 13 of the upper lid 11 and the outer surface of the straight protective duct 31. Is closed all around the outer surface.

  Next, the attachment of the decorative cover 1 to the wall penetrating portion when the corrugated protective duct 41 is provided in place of the straight protective duct 31 at a bent portion, a detour portion or the like of the wiring piping path will be described.

  First, after penetrating the refrigerant pipe P into the through hole 53 of one of the wall members 51, the slit formed continuously in the longitudinal direction in the corrugated protective duct 41 is expanded to both sides, The refrigerant pipe P is covered from the formed slit opening so that the refrigerant pipe P is accommodated therein, and the tip surface of the corrugated protection duct 41 is brought into contact with or close to the wall surface 54 of one wall member 51, and the other Arrange along the wall surface 55. Here, if the corrugated protective duct 41 cancels the expansion of the split portion, the split portion is elastically restored to the original closed state, and the refrigerant pipe P is entirely surrounded by the corrugated protective duct 41. Be surrounded.

  Next, while holding the corrugated protection duct 41, the top cover 11 of the decorative cover 1 is made to approach from the direction perpendicular to the other wall surface 55 and perpendicular to the longitudinal direction of the corrugated protection duct 41. 11, the protrusion 16 at the receiving port 13 of the upper lid 11 is pushed into the annular recess 43 on the distal end side of the corrugated protection duct 41 so as to reach the entire circumference except the surface facing the wall surface 55. . Here, since a space that can accommodate the annular convex portion 42 of the corrugated protection duct 41 is formed on the inner surface 13 a of the receiving port 13, the protrusion 16 of the upper lid 11 has a surface facing the wall surface 55. The entire circumference can be surely entered. Next, a screw 56 is inserted into the fixing hole 15 of the decorative portion 12 of the upper lid 11 and screwed to one wall surface 54 to fix the upper lid 11. As a result, the corrugated protective duct 41 slightly expands and contracts in the longitudinal direction, the front end surface abuts on the wall surface, or is disposed close to the wall penetrating portion at a predetermined position, and the protruding portion of the wall hole 53 Is covered by the decorative part 12 of the upper lid 11.

  As a result, the corrugated protective duct 41 is formed so that the protrusion 16 of the upper lid 11 enters along the entire circumference except for the surface facing the wall surface 55 in the annular recess 43 and is hooked so that Is prevented from being removed. Then, the protrusion 16 enters the annular recess 43 of the corrugated protection duct 41 so that the gap between the opening 14 of the receiving port 13 and the corrugated protection duct 41 is closed. The surface facing the wall surface 55 in the corrugated protection duct 41 is a portion that is not concealed from the ridge 16 but is cut out, but is concealed from the outside. Not affected by appearance.

  Next, the description has been given of the attachment to the wall penetrating portion when the decorative cover 1 is constituted by the upper lid 11 alone. However, the wall when the decorative cover 1 is constituted by assembling the upper lid 11 and the lower lid 21 is described. The attachment to a penetration part is demonstrated based on FIG.12 and FIG.13. Here, the case where the protective duct is the straight protective duct 31 will be described. However, the same applies to the case where the protective duct 41 is a corrugated protective duct 41, and the description thereof will be omitted.

  12 and 13, a wall hole 53 formed in one wall member 51 is used to prevent the cover portion or the like of a piercing tool that forms the hole from interfering with the other wall surface 55, or Depending on the surrounding situation in the penetrating portion, the other wall member 52 may be provided at a position separated from the wall surface 55 to some extent. In the case where the wall hole 53 is provided at such a position spaced apart to some extent, the straight protective duct 31 may be disposed in the air separated from the wall surface 55 in addition to the refrigerant pipe P. In this case, the lower cover 21 is further attached to the gap between the wall surface 55 and the straight protective duct 31 in the decorative cover 1, and the decorative cover 1 in which the upper cover 11 and the lower cover 21 are assembled is used. It is done.

  Therefore, first, the lower cover 21 of the decorative cover 1 is disposed at a predetermined position on one wall surface 54, the decorative portion 22 of the lower cover 21 is brought into contact with the wall surface 54, and the screw 56 is inserted into the fixing hole 24. Screw onto the wall surface 54 and fix. Next, in the same manner as in the above embodiment, the refrigerant pipe P is passed through the wall hole 53, and the straight protective duct 31 is disposed away from the wall surface 55 along the wall surface 55. At this time, the front end surface of the straight protective duct 31 comes into contact with the wall surface 54 or is inserted into the wall hole 53.

  Next, the upper cover 11 of the decorative cover 1 is made to approach from the direction orthogonal to the straight protective duct 31 so that the receiving port 13 of the upper cover 11 is fitted to the straight protective duct 31 and is attached to the lower cover 21. . At this time, by pushing the upper lid 11 toward the lower lid 21, the engagement convex portion 17 b on the back surface side of the upper lid 11 is engaged with the engagement concave portion 25 b on the rear surface side of the lower lid 21, and the lower lid 21 is engaged. The rear surface side engaging convex portion 25 a engages with the rear surface side engaging concave portion 17 a of the upper lid 11. Further, the fitting convex portion 26 on the surface side of the lower lid 21 is fitted with the fitting concave portion 18 of the upper lid 11, and the left and right end portions of the decorative portion 12 of the upper lid 11 are sandwiched by the engagement pieces 25 of the lower lid 21. To do. Thereby, the upper lid 11 can be easily assembled to the lower lid 21 attached to one wall surface 54, and the upper lid 11 and the lower lid 21 are held in a stable assembled state.

  When the decorative cover 1 is attached in this manner, the wall hole 53 is completely closed by the decorative portion 12 of the upper cover 11 and the decorative portion 22 of the lower cover 21 in the same manner as in the above embodiment. Is prevented from being exposed to the front side of the wall. Further, the gap between the outer surface of the straight protective duct 31 and the opening 4 of the receiving port 3 of the decorative cover 1 reaches the entire circumference and is covered with the protrusion 16.

Next, the operation of the decorative cover of the present embodiment configured as described above will be described.
The protrusion 16 projecting inward of the receiving port 3 of the decorative cover 1 is inserted into the annular recess 43 of the corrugated protective duct 41 inserted into the receiving port 3 and is inserted into the receiving port 3. The gap between the straight protective duct 31 and the receiving port 3 is closed along the outer surface of the straight protective duct 31. As a result, both the straight protective duct 31 and the corrugated protective duct 41 can be attached to the same decorative cover 1, and in any of these cases, the protrusion 16 is the receiving port 3 of the decorative cover 1. By covering the gap between the opening 4 and the outer surface of the protective duct, the appearance of the wall penetration portion is improved. As a result, by providing these two conditions, one decorative cover 1 can be used as both the straight protective duct 31 and the corrugated protective duct 41.

  In the above embodiment, the protrusion 16 of the decorative cover 1 is attached along the outer surface of the straight protective duct 31 and is fitted into the annular recess 43 of the corrugated protective duct 41. In terms of dimensions, the inner diameter of the straight protective duct 31 and the inner diameter of the annular recess 43 of the corrugated protective duct 41 are substantially equal, that is, the inner volumes of both are substantially equal. For this reason, in the piping state in which both the straight protective duct 31 and the corrugated protective duct 41 are disposed in the same wiring piping path, the two types of protective ducts are in the state where the accommodation density is substantially equal, and the refrigerant pipe P Etc. can be accommodated. Therefore, it is possible to avoid the problem that any one of the protective ducts is accommodated in a state where a plurality of pipes such as the refrigerant pipe P and the drain pipe are extremely densely packed or conversely accommodated in a cluttered state.

  By the way, in each said embodiment, although the cover part 37 of the cover 33 of the straight protection duct 31 is formed in the cover shape which curved gently upwards, as shown in FIG. In the case where the depression 39 is formed along the longitudinal direction at the location, the projecting portion 16 of the decorative cover 1 also corresponds to the shape thereof, and the front end surface 16a is within the depression 39 of the straight protective duct 31. The shape of the cover 33 extends along the outer surface of the cover 37.

  Moreover, in each said embodiment, although the protrusion 16 of the upper cover 11 of the decorative cover 1 is provided along the perimeter of the outer surface except the contact part to the wall surface of the straight-shaped protection duct 31, it protects. It is not necessary to provide in a portion where no gap is formed between the outer surface of the duct and the inner surface 13a of the receiving port 13, and in this case, it is provided along a part of the outer surface excluding the contact portion with the wall surface of the protective duct. Become. For example, as shown in FIGS. 15 and 16, the straight protective duct 31 is formed with depressions 39 along the longitudinal direction of the cover 33 at two locations in the width direction of the cover portion 37 of the cover 33. Concave portions 40 are formed in the left and right side walls 35, and inclined surfaces directed inward are formed at the lower ends of the left and right side walls 35 of the base 32. Only in these portions, the insertion holes 13 of the upper lid 11 are inserted after insertion. When a gap is formed between the inner surface 13 a and the protrusion 16 of the upper lid 11, it is only necessary to provide a portion of the outer surface of the straight protective duct 31 where these gaps are generated.

  The upper lid 11 shown in FIG. 15 and FIG. 16 shows what is attached to the floor surface 58 of the floor material 57 as a wall material, and the fixed portion to the floor material 57 is fixed to the left and right lower end portions of the upper lid 11. A fixing hole 15 is formed through the fixing seat. In the case of the upper lid 11, the left and right ridges 16 enter the recesses 40 of the left and right side walls 35 of the base 32 of the straight protective duct 31. After the 31 is installed on the flooring 57, the upper lid 11 cannot be attached from above, and after the upper lid 11 is first attached to the wall material 51, the upper lid 11 is placed in the opening 14 of the receiving port 13 of the upper lid 11. The tip of the straight protective duct 31 is inserted. However, if the upper lid 11 is elastically expanded to both the left and right sides, after the straight protective duct 31 is first installed on the flooring 57, the straight shape is obtained while the upper lid 11 is expanded to the left and right sides. It is also possible to attach to the protective duct 31 from above.

  In the upper lid 11 shown in FIGS. 15 and 16, the triangular gap formed between the bottom surface of the both side walls 35 of the base 32 of the straight protective duct 31 and the floor surface 58 has protrusions. The part 16 is not provided. This is because the contact point with the floor surface 58 is hardly visible from the outside, so that it is not necessary to provide it in terms of appearance. That is, the protrusion 16 must be provided along the outer surface of the protective duct at least in a portion visually recognized from the outside, and should not be provided in a portion that is not visually recognized from the outside or a portion that is hardly conspicuous. Also good. However, the protrusions 16 may be provided at these portions.

  Next, when the corrugated protective duct 41 is inserted into the receiving port 13 of the upper lid 11 shown in FIGS. 15 and 16, the state shown in FIG. 17 is obtained. The straight protective duct 31 shown in FIG. 15 and FIG. 16 has a shape in which a recess 39 is provided in the cover 33 and a recess 40 is provided in the base 32, which is provided in the receiving port 13 of the upper lid 11. It can also be said that it is formed corresponding to the engaging piece that enters and locks into the annular recess 43 of the corrugated protection duct 41. That is, the protrusion 16 of the upper lid 11 is also an engagement piece that enters and locks into the annular recess 43 of the corrugated protection duct 41, and the straight protection duct is to avoid interference with the engagement piece. It is also formed in the shape. However, in the case of the straight protective duct 31, the inner volume is reduced by the amount of the depression 39 and the concave portion 40 projecting to the inner side, and the outer shape is locked to the annular concave portion 43 of the corrugated protective duct 41. The shape corresponding to the engagement piece is restricted.

  By the way, although the protrusion 16 is provided on the upper lid 11, it may be provided on the lower lid 21, or may be provided on both the upper lid 11 and the lower lid 21. Further, the front end surface 16a of the protrusion 16 of the decorative cover 1 may be chamfered at the corners in an R shape. In this case, the corrugated protective duct 41 is inserted into the annular recess 43. It becomes easy.

  Furthermore, if the protrusion 16 of the decorative cover 1 is rigid at least so as to be hooked on the annular recess 43 of the corrugated protective duct 41 and prevent it from being pulled out, it is entirely or partially thin film-like. It is good also as what is formed in and bent in the front-back direction elastically. In this case, it is possible to insert the corrugated protective duct 41 into the opening 4 from the front side of the receiving port 3 of the decorative cover 1 while slightly deforming the front end portion. As a result, after the decorative cover 1 is first fixed to the wall surface 54, the corrugated protective duct 41 can be inserted into the opening 4 of the decorative cover 1 while expanding and contracting in the longitudinal direction. Similarly, at 31, the decorative cover 1 can be inserted into the opening 4 after being fixed. Therefore, in this case, the fixing operation of the decorative cover 1 can be performed in a relatively wide space where the protective ducts are not disposed, so that the fixing operation can be performed easily and reliably.

Next, a decorative cover according to another embodiment of the present invention will be described with reference to FIGS.
18 and 19, the protrusion 16 provided at the receiving port 13 of the top cover 11 of the decorative cover 1 has a long protruding amount into the opening 14, and 2 as indicated by a two-dot chain line in the middle portion thereof. A U-shaped break groove 16b is formed at one location, and can be broken at either one of the two-point break grooves 16b, as shown in FIG. It can also be. In this case, the single decorative cover 1 can cope with a plurality of types of protective ducts having different outer sizes.

<Second embodiment>
Next, the decorative cover of the wall penetration part of 2nd embodiment of this invention is demonstrated based on FIG. 20 thru | or FIG. 20 and 21 show the decorative cover of the second embodiment, FIG. 20 is a perspective view thereof, and FIG. 21 is a cross-sectional view taken along the line DD in FIG.

  20 and 21, the decorative cover 1 of the second embodiment has basically the same configuration as the decorative cover 1 of the first embodiment, and is different in the following points. First, in the decorative cover 1 of the second embodiment, the ridge 16 is not formed on the upper lid 11, while the inner surface 13 a from the opening 14 to the inner surface 13 a at the back in the center of the upper wall portion of the receiving port 13 of the upper lid 11. A rectangular plate-shaped projecting piece portion 19 is provided that protrudes inward and orthogonal to 13a. Next, the receiving port 3 of the decorative cover 1 according to the second embodiment is formed along the outer surface so as not to create a gap between the outer surface of each protective duct and the inner surface of the receiving port 3. The inner surface of the receiving port 3 is formed so as to be in close proximity to the outer surface of each of the protective ducts so that almost no gap is generated. The straight protective duct 31 and the corrugated protective duct 41 inserted into the receiving port 3 have the same outer shape and size.

  The decorative cover 1 of the second embodiment is also configured by assembling the upper lid 11 and the lower lid 21 in the same manner as the decorative cover 1 of the first embodiment, but is configured only by the upper lid 11. However, the upper lid 11 is often used alone due to the arrangement of protective ducts and the like in the wall penetration portion. Here, the projecting piece portion 19 provided in the back of the receiving port 13 of the upper lid 11 is configured so that the straight protective duct 31 is inserted when the straight protective duct 31 is inserted into the receiving port 3 of the decorative cover 1. It abuts against the tip surface of 31 and restricts further entry. Accordingly, in FIG. 20 and FIG. 21, the protruding piece 19 is formed at the center of the upper wall portion of the receiving port 13 of the upper lid 11, but other side wall portion of the receiving port 13, for example, or the upper wall It may be formed on both the wall portion and the side wall portion, or may be provided in the receiving port 23 of the lower lid 21. Furthermore, you may provide in the perimeter along the periphery of the opening 4 of the receptacle 3 of the said decorative cover 1. FIG.

  Since the protruding piece 19 enters the annular recess 43 of the corrugated protection duct 41, it is formed to have a thickness smaller than the width of the annular recess 43. Further, since the front end surface of the straight protection duct 31 comes into contact with the annular recess 43 of the corrugated protection duct 41, the projecting length of the projecting piece portion 19 is such that the front end surface 19a is annular. It is sized to abut against the outer surface of the recess 43 or to be located outside the outer surface, and to be located on the inner side of the outer surface of the straight protective duct 31. However, the straight protective duct 31 and the corrugated protective duct 41 are formed to have the same outer shape and size, so long as the projecting length enters the annular recess 43 of the corrugated protective duct 41. The front end surface 19 a is naturally positioned on the inner side of the outer surface of the straight protective duct 31, and the projecting piece 19 comes into contact with the front end surface of the straight protective duct 31.

Next, attachment in the wall penetration part of the decorative cover and protection duct of 2nd embodiment is demonstrated.
Similarly to the decorative cover 1 of the first embodiment, the decorative cover 1 of the second embodiment is used by assembling the upper lid 11 and the lower lid 21, or is composed of only the upper lid 11 and the upper lid 11 alone. used. However, in the decorative cover 1 of the second embodiment, the protruding piece portion 19 provided in the back of the receiving port 13 of the upper lid 11 abuts on the front end surface of the straight protective duct 31 to restrict further entry. Therefore, prior to the installation of the straight protective duct 31, it is attached to the wall penetration part.

  Therefore, as shown in FIG. 22, a case will be described in which the base 32 of the straight protective duct 31 is installed in contact with the wall surface 55 of the wall material 52. In this case, the decorative cover 1 is used with only the upper lid 11. First, in a state where the refrigerant pipe P is inserted into the through hole 53 of the wall material 51, the decorative cover 1, that is, the upper lid 11 is attached so that the entire through hole 53 is covered with the decorative portion 12. The upper lid 11 can be attached by inserting a screw 56 through the fixing hole 15 of the decorative portion 12 and screwing it onto the wall member 51. At this time, since the straight protective duct 31 is not yet installed in the wall penetrating portion, the screw 56 can be screwed in a relatively large space, so that the decorative cover 1 can be fixed easily and reliably. Can do.

  Next, the straight protective duct 31 is inserted into the receiving port 3 of the decorative cover 1 from the longitudinal direction. Here, since the projecting piece 19 protrudes inward in the receiving port 3, the front end surface of the straight protective duct 31 abuts on the projecting piece 19, and further back Entry into the is restricted.

  When installing the corrugated protective duct 41, the refrigerant pipe P is connected to the through hole of the wall member 51 as shown in FIG. 23 in the same manner as the corrugated protective duct 41 of the first embodiment shown in FIG. 53, the corrugated protective duct 41 is arranged along the wall surface 55, and while holding it, the decorative cover 1 is fixed to the wall surface 54 of the wall material 51, and the projecting piece 19 is connected to the corrugated protective duct. What is necessary is just to insert in the annular recessed part 43 of 41. As a result, in the corrugated protective duct 41, the annular recess 43 is engaged with the projecting piece portion 19, and removal from the decorative cover 1 is prevented.

  Thus, when the decorative cover 1 is installed in the wall penetrating portion, the receiving port 3 of the decorative cover 1 is formed along the outer surface of each protective duct. There is almost no gap between the protective ducts. Therefore, the appearance at the receiving port 3 is improved. Here, when the corrugated protection duct 41 is inserted in the back of the receiving port 13, the projecting piece portion 19 opens the opening 13 of the receiving port 13 in the depth direction. If it is set so as to be disposed at the end, after insertion, the annular convex portion 42 of the corrugated protection duct 41 is located at the opening end of the receiving port 13, and the opening 14 of the receiving port 13 and the There is almost no gap between the annular convex portion 42 of the corrugated protection duct 41 and the appearance of the wall penetration portion is further improved.

  In the second embodiment, the attachment to the wall penetrating portion when the decorative cover 1 is configured by assembling the upper lid 11 and the lower lid 21 is the first shown in FIGS. 12 and 13. Since it is the same as that of an embodiment, the explanation is omitted.

  By the way, as shown in FIG. 24, the said decorative cover 1 of 1st embodiment is in the back from the opening edge part in which the protrusion part 16 is provided in the receptacle 4, similarly to the decorative cover of 2nd embodiment. You may further provide the approach control protrusion 20 which controls the approach of a protection duct. In this case, when the protective duct is inserted into the receiving port 3 after the decorative cover 1 is attached to the wall surface 54, it is possible to prevent further inward entry. Then, the tip of the corrugated protection duct 41 is set in advance by setting the distance between the protrusion 16 and the entry restricting projection 19 to be equal to the distance between the tip of the corrugated protection duct 41 and the annular recess 43. When the surface is abutted against the entry restricting protrusion 20, the annular convex portion 42 of the corrugated protective duct can be naturally positioned at a position corresponding to the protruding portion 16.

  Also in the decorative cover 1 of the second embodiment, the upper lid 11 and the lower lid 21 are divided into two at the lower edge of the opening 4, but vertically or horizontally at the intermediate position in the width direction of the opening 4. It may be divided into two.

  And although the wiring / pipe material in each of the above embodiments shows the refrigerant pipe P for an air conditioner, it goes without saying that it may be a wiring material such as a cable or a piping material such as a water supply / hot water supply pipe.

  Furthermore, although the decorative cover 1 in each of the above embodiments is shown attached to a wall material of a building, it is similarly applied to a peripheral wall material of a box used as a flooring material or wiring piping material.

  In addition, the straight protective duct 31 of each of the above embodiments is formed by assembling a two-part body of the base 32 and the cover 33, but is not limited to this, and the base 32 and the cover 33 are interposed between them. It may be formed integrally by being connected by a hinge or the like provided in the case, or it may be formed in a single cylindrical shape. Further, the straight protective duct 31 and the corrugated protective duct 41 of each of the above embodiments are formed in a rectangular frame shape, but are not limited to this, and are formed in a cylindrical shape, a trapezoidal frame shape, or the like. There may be.
