Describes first the protective cover A _1, subsequently, be described fitting maintaining member M ₁ attached to a base V of the protective cover A _1. The protective cover A ₁ of this embodiment accommodates a refrigerant pipe for an air conditioner and is attached to a wall surface of a building in an exposed state, and is fitted with a base V fixed to the wall surface and a cover lid on the base V. And a lid C to be joined. Both the base V and the lid C are extruded products of resin.

  Moreover, the base V consists of the bottom wall part 1 and the side wall part 2 which stood up integrally at the both ends of the width direction, and the upper surface opened. The side wall portion 2 is bent in a cross-sectional view so that a central portion in the height direction slightly protrudes inward, and an upper end portion thereof is bent toward an oblique lower side on the inside. The bent piece 3 is formed. For this reason, the outer side surface of the central portion in the height direction of each side wall portion 2 is formed in a concave shape along the longitudinal direction, and the displacement preventing projection 4 is provided in the concave portion at a constant interval in the longitudinal direction. A base-side fitting portion 5 having a hook shape is provided immediately below the misalignment stop protrusion 4 in the longitudinal direction in a state of facing obliquely downward. Moreover, each side wall part 2 of the base V is bent so that the center part in the height direction protrudes to the innermost side, and the most protruding surfaces inside each side wall part 2 are planes facing each other. It is part 6.

  On the other hand, the overall shape of the lid C is bent in an inverted U shape, and side walls 8 are continuously provided on both sides of the curved top wall 7 so that the lower surface is open. is doing. Another misalignment projection 9 corresponding to the misalignment projection 4 of the base V is provided at a predetermined interval along the longitudinal direction at a portion slightly above the lower end of the inner surface of each side wall 8. In the lower end of each of the side wall portions 8 and directly below the misalignment projection 9, the same lid-shaped lid side fitting that fits with the base-side fitting portion 5 having a bowl shape is mutually fitted. The joint portion 11 is continuously provided along the longitudinal direction in a state of being directed obliquely upward. The displacement preventing projections 4 and 9 of the base V and the lid C are made to abut the rotating body on which the projections corresponding to the outer peripheral surface are formed at the corresponding portions of the base V and the lid C at the time of extrusion molding. While being rotated, the base V and the lid C are simultaneously molded.

The base V and the lid C are fixed to the wall surface and the air conditioner refrigerant pipe P is accommodated in the base V, as shown in FIGS. When the lid C is pushed in from directly above the base V, each side wall 2 of the base V is slightly inside immediately before the fitting portions 5 and 11 on the base side and the lid side having a bowl shape are fitted. The side wall portions 8 of the lid C are slightly elastically deformed outward and the lid side fitting portion 11 passes through the base side fitting portion 5 and is elastically deformed. The side wall portions 2 and 8 on the base side and the lid side are restored to the current shape, and the fitting portions 5 and 11 are fitted to each other. 9 are fitted to each other so that the base V and the lid C are not displaced in the longitudinal direction. In this way, even when the base V and the lid C are fitted, the base V or the lid C is thermally deformed due to solar heat or the like, or when an impact force acts on this. The base V and the lid C may be disengaged as described in “Background Art”. In the protective cover device according to the present invention, since the fitting force between the base V and the lid C is enhanced by the action of the fitting maintaining member M ₁ , When the deviation along the longitudinal direction does not occur, it is not necessary to provide each of the deviation stop protrusions 4 and 9.

Therefore, in the present invention, various fitting retaining member M ₁ ~M ₄ for maintaining a fitting state of a base V and the cover C is used. As shown in FIGS. 1 to 4, the fitting maintaining member M ₁ of the first embodiment is formed by bending a strip-shaped metal thin plate made of stainless steel or the like so as to be elastically deformable. The base V is attached in the accommodated state. The fitting maintaining member M ₁ includes a bottom plate portion 21 that is in contact with the bottom wall portion 1 of the base V, each side plate portion 22 in which both ends of the bottom plate portion 21 are bent upward in an upright state, and each side plate portion 22.

It has become. The fitting maintaining member M ₁ is elastically deformable and has “spring property” in a state where the thin metal plate is bent or bent as described above. Further, the bottom plate portion 21 of the fitting maintaining member M ₁ is provided with a through hole 25 through which a screw B used for fixing the base V of the protective cover A ₁ to the wall surface of the building is passed.

Then, in a state of being expanded both side walls 2 of the base V outward, to accommodate the bottom plate 21 and side plate portions 22 of the fitting retaining member M ₁ therein, when opening the expansion 2 and 4 (a), the bottom plate portion 21 and both side plate portions 22 abut against the bottom wall portion 1 of the base V and the flat portion 6 of the side wall portion 2, respectively, and The bending engagement portion 23 is engaged with the bending piece 3 so as to cover the bending piece 3 of the base V, and the lid pressing portion 24 slightly protrudes from the opening of the base V. It becomes a state. Further, as shown in FIG. 4A, in the state where the fitting maintaining member M ₁ is attached to the base V, the lid pressing portion 24 interferes with the lid C fitted to the base V. (In other words, when the lid C is fitted to the base V, the fitting maintaining member M ₁ has its lid pressing portion 24 pressed the back surface of the top wall portion 7 of the lid C. In the state, the whole is slightly elastically deformed). As shown in FIG. 3, the fitting maintaining member M ₁ is attached to the inside of the base V at a predetermined interval.

For this reason, piping of the air conditioning refrigerant pipe P using the fitting maintaining member M ₁ is performed as follows. First, as shown in FIGS. 2 and 3, the through hole 12 provided in the bottom wall ₁ of the base V of the protective cover A ₁ and the through hole 25 of the fitting maintaining member M ₁ are matched. The fitting maintaining member M ₁ is attached in the base V as described above, and the base V is arranged along the predetermined direction on the outer wall of the building. Screws B are respectively passed through the through holes 12 and 25 of the fitting maintaining member M ₁ to fix the base V to the outer wall W of the building. Next, the air conditioner refrigerant pipe P is accommodated inside the base V, and then the lid C is pressed from the opening side of the base V fixed to the outer wall W to cover it, as described above. At the same time that the fitting portions 5 and 11 on the base side and the lid side are fitted to each other, the displacement preventing projections 4 and 9 of the base V and the lid C are arranged at positions where they do not interfere along the longitudinal direction. Then, the lid C is fitted to the base V in a covered state.

Then, when the lid C is fitted in a cover state to the base V having the fitting maintaining member M ₁ attached therein as shown above, it is shown in FIGS. As shown, the lid C presses the lid pressing portion 24 of the fitting maintaining member M ₁ downward, and the both side walls 2 of the base V are deformed inward, thereby maintaining the fitting. The member M ₁ is mainly deformed elastically with the lid pressing part 24 as a main body, and the fitting maintaining member M ₁ is slightly retracted toward the bottom wall 1 side of the base V. As a result, by the restoring force of the fitting maintaining member M ₁ , the lid pressing portions 24 at both upper ends press the back surface of the top wall portion 7 of the lid C and are fitted to each other. And the said pressing force F reaches each fitting part 5 and 11 by the side of a cover body, and the fitting state of both the fitting parts 5 and 11 becomes firm. In particular, since each of the fitting portions 5 and 11 of the first embodiment described above is formed in a bowl shape, it is difficult to come off due to its shape itself. Combined with the action of strengthening the state, the fitting state of the fitting parts 5 and 11 on the base side and the lid side is ensured and can be maintained for a long time.

On the other hand, when the lid C is removed from the base V due to some necessity, when the lid C is pressed against the base V as shown in FIG. While expanding outward, both side wall portions 2 of the base V are slightly pushed down inward, and the left and right and upper and lower sides of the fitting portions 5 and 11 on the base side and the lid side The fitting state is released after separating in both directions. Further, in the portion where the fitting maintaining member M ₁ is attached, when the lid C is removed, it is attached to the inside of the base V as shown by a two-dot chain line in FIG. The fitting maintaining member M ₁ is further elastically deformed beyond its attached state.

Further, as shown in FIG. 6A, in a state where the fitting maintaining member M ₂ is attached to the inside of the base V, each side plate portion 33 of the fitting maintaining member M ₂ is connected to each side wall of the base V. The portion 2 is opposed to the portion 2, a part of which is in contact with the flat surface portion 6 of the base V, and the bending engagement portions 32 of the base V are covered with the two bent pieces 3. Further, the lid pressing portion 31 is engaged with this, and covers the opening of the base V. Further, as shown in FIG. 6 (b), in the state of attaching the fitting retaining member M ₂ to the base V, the lid pressing portion 31, a position interfering with the lid C which is attached to the base V It is in. For this reason, when the lid C is fitted to the base V to which the fitting maintaining member M ₂ is attached, the lid pressing portion of the fitting maintaining member M ₂ as shown in FIG. 31 is pressed by the cover body C, and both side wall portions 2 of the base V are deformed inward, whereby the fitting maintaining member M ₂ is elastically deformed and the bottom wall of the base V It is slightly retracted to the part 1 side. Thereby, the cover body pressing part 31 after elastic deformation presses the back surface of the top wall part 7 of the cover body C against the base V upward. And this pressing force F acts so that the fitting state of each fitting part 5 and 11 of the base V and the cover body C may be strengthened.

FIG. 7 shows a use state of the fitting maintaining member M ₃ of the third embodiment of the present invention. Unlike the above-described fitting maintenance members M ₁ and M ₂ , the fitting maintenance member M ₃ is attached to the outside of the base V, and the top wall portion 7 of the lid C is formed by elastic restoring force. A lid pressing portion 41 that presses the back surface, a concave portion 42 that is connected to both ends of the lid pressing portion 41 and a part of which is in contact with the upper surface of the bent piece 3 at the upper end of the base V; A side plate portion 43 that is provided outside the concave portion 42 and is in contact with the outside of the substantially upper half of the side wall portion 2 of the base V, and a lower end of the side plate portion 43 that is bent inward. In addition, it is composed of four portions with the engaging portion 44 that is engaged with the concave portion 13 provided on the outer side surface of the base V immediately above the misalignment projection 4 and has a symmetrical shape.

Further, as shown in FIG. 7 (a), in the state of attaching the fitting retaining member M ₃ with respect to the base V, the opening of the base V, and the upper half of the both side walls 2 fitted covered by engagement maintaining member M _3, the fitting retaining member M ₃ are, the engagement portion 44 of both the lower end, is engaged with the concave portion 13 of the base V, are gone out taken from the base V . Further, as shown in FIG. 7A, in a state where the fitting maintaining member M ₃ is attached to the base V, the lid pressing part 41 interferes with the lid C attached to the base V. It is in. For this reason, when the lid C is fitted to the base V to which the fitting maintaining member M ₃ is attached, the lid pressing portion 41 is lowered by the lid C as shown in FIG. When the both side wall portions 2 of the base V are deformed inwardly, the fitting maintaining member M ₃ is mainly formed with the lid pressing portion 41 at the center thereof as a main component. The whole is elastically deformed and slightly retracted toward the bottom wall 1 side of the base V. And the cover body pressing part 41 after elastic deformation presses the back surface of the top wall part 7 of the cover body C upward against the base V, and each of the base V and the cover body C by this pressing force F. The effect | action which the fitting state of the fitting parts 5 and 11 becomes firm is the same as said each Examples 1 and 2.

Further, FIG. 8 shows a use state of the fitting maintaining member M ₄ of the fourth embodiment of the present invention, and FIG. 9 shows the fitting maintaining member M ₄ itself. This fitting maintenance member M _{4 is} also attached to the outside of the base V, but differs from the fitting maintenance member M ₃ in that it is attached only to the opening portion. That is, the fitting maintaining member M ₄ is arranged in a state of covering the opening of the base V, and the lid pressing portion 51 that presses the back surface of the top wall portion 7 of the lid C by elastic restoring force, and the lid A hooking portion 52 that is connected to both ends of the pressing portion 51 and is hooked on the tip of both bent pieces 3 of the base V, and a portion in the width direction of the portion where the hooking portion 52 is formed in a cross-sectional view. The center portion is formed by cutting and raising upward, and is composed of three parts: an abutment plate portion 53 that is in contact with the outside of the inwardly bent portion of the upper end portions of the side wall portions 2 of the base V. In the same way, it has a symmetrical shape. For this reason, since each hook part 52 formed at both ends of the lid pressing part 51 cuts and raises the abutting plate part 53, the center part thereof is omitted.

In the state of attaching the fitting retaining member M ₄ the base V, as shown in FIG. 8 (b), each engaging portion 52 at both ends of the fitting retaining member M ₄ are, each of the base V While being hooked on the tip of the bent piece 3, its abutment plate portion 53 is brought into contact with the outer surface of the inwardly bent portion of the upper end portions of the side wall portions 2 of the base V, and the lid body. The opening of the base V is covered by the pressing portion 51, and the lid pressing portion 51 is in a position where it interferes with the lid C attached to the base V. For this reason, when the lid C is fitted to the base V to which the fitting maintaining member M ₄ is attached, the lid pressing portion 51 of the fitting maintaining member M ₄ is moved downward by the lid C. When the two side walls 2 of the base V are deformed inwardly, the lid pressing portion 51 is mainly deformed and elastically deformed substantially by the restoring force. The body C is pressed upward against the base V. This pressing force F acts so that the fitting state of the fitting portions 5 and 11 of the base V and the lid C becomes strong. The fitting maintaining members M ₂ , M ₃ , and M ₄ need to be attached to the base V after the air conditioner refrigerant pipe P is accommodated in the base V.

Further, in FIG 10, a protective cover for protecting houses the wiring and piping material inside the fitting of the fitting portions of the hook-like respectively provided with "base and the lid, the base In the non-deformed state, the distal end portion of each side wall portion of the base interferes with the lid body, and in the fitted state with the lid body, due to elastic deformation of a portion of the side wall portion on the free end side relative to the fitted portion. A pressing portion is formed to increase the fitting force of each fitting portion between the base and the lid by pressing the lid in a direction away from the base bottom wall by contacting the back surface of the lid. An example of a "protective cover characterized in that it is provided " is shown. As this protective cover, “the pressing portion of the base retreats toward the bottom wall portion of the base due to its own elastic deformation or elastic deformation of the side wall of the base when the lid is fitted. Then, after the fitting, there is a configuration in which the pressing portion is restored to the original shape and presses the inner surface of the lid upward, and further, the pressing portion of the base is In addition, there is a configuration in which “the configuration is provided at the tip of the side wall portion of the base”.

Next, the protective cover A ₂ shown in FIG. 10 will be specifically described. The protective cover A ₂ is composed of a base V and a lid C fitted to the base V in a cover state, and is slightly above the lower end outside the both side walls 2 of the base V. Is provided with a base-side fitting portion 5 having a bowl shape, and a lid-side fitting that fits with the base-side fitting portion 5 at the lower ends of both side wall portions 8 of the lid C. A joint portion 11 is provided, and a pressing portion 14 having a U-shaped cross section that opens upwardly obliquely is integrally formed over the entire length at the distal end portion (the free end portion) of both side wall portions 2 of the base V. The tip of the pressing portion 14 is provided at a position where it interferes with the lid C in the non-deformed state. Therefore, when the air conditioner refrigerant pipe P is accommodated in the base V and then the lid C is covered and fitted, the tip of the pressing portion 14 of the base V is the back of the top wall 7 of the lid C. The upper half of the both side walls 2 of the base V is elastically deformed inward. For this reason, the pressing portion 14 presses the back surface of the lid C upward with respect to the base V by the elastic restoring force of the above-described portions of the side wall portions 2 of the base V. The fitting state between V and the lid C is strengthened.

The protective cover A ₂ of the above embodiment can increase the fitting force between the base V and the lid C without using a separate member, and also has a pressing portion at the tip of the side walls 2 of the base V. Since 14 is provided over the entire length, the fitting force between the base V and the lid C is further increased, and the pressing portion 14 having a U-shaped cross section has its opening facing obliquely upward. Therefore, it does not become an obstacle when accommodating the refrigerant pipe P for air conditioner in the base V. In addition, if the shape of the press part provided in the front-end | tip part of the side wall part 2 of the base V is brought close to an upright shape, the amount of elastic deformation can be made the same and the pressing force with respect to the cover body C can be raised.

  Further, in the embodiment shown in FIG. 11, a plurality of spring materials S are attached to the back surface of the lid C at a predetermined interval, and after the air conditioner refrigerant pipe P is accommodated in the base V, When the cover body C is fitted to the base V in a cover state, the lower end of the spring material S comes into contact with the air conditioner refrigerant pipe P accommodated in the base V and is compressed and deformed. For this reason, the back surface of the lid C is pressed upward against the base V by the restoring force of the spring material S that has been compressed and deformed, and this pressing force F is fitted between the base V and the lid C. Strengthen the state. Since the spring material S is attached to the back surface of the lid C via a screw or the like, the spring material S does not fall when performing piping work on the wall surface of the building, so that the work can be performed without any trouble. The spring material S may be attached to the side of the air conditioner refrigerant pipe P accommodated in the base V, and a separate spring material may be provided between the lid C and the air conditioner refrigerant pipe P. It may be interposed.

  In addition, the protective cover of each of the above embodiments has a structure in which the base V and the lid C are separated from each other, and the two are fitted in two places on the left and right. The lid can be hinged on one side wall portion, and the present invention can be applied to a protective cover in which both sides are fitted only on the other side wall portion.

  Furthermore, in each said Example, each fitting part 5 and 11 provided in the base V and the cover body C is a bowl-shaped thing, and there exists an advantage with large fitting force from the shape. As described above, in the present invention, the shape of each fitting portion between the base V and the lid C is not limited to the above-mentioned bowl shape, and the purpose of fitting can be achieved even with a simple concavo-convex structure. Anything can be used. Further, the member accommodated and protected by the protective cover composed of the base and the lid may be a piping material such as a water supply / drainage pipe other than the air conditioner refrigerant pipe, a gas pipe, and a wire such as an electric wire. It may be a material.
