Description

  The present invention consists of a base fixed to the wall surface of a building and a lid body covered by the base, and a linear portion that protects the linear portion of the wiring / piping material disposed along the wall surface The present invention relates to an attached protective cover that is provided with a connection port connected to an end portion of the protective cover and protects a bent portion, a branched portion, a protruding corner portion, or an entering corner portion of a wiring / pipe material. In the present specification, “wiring / piping material” refers to a hot water supply pipe, a refrigerant pipe for an air conditioner, an electric wire, a cable, and the like.

  For example, in order to protect the bent and branched pipes of the hot water pipe, the base and lid that make up the attached protective cover that is installed and fixed on the flat part of the wall surface are engaged on both sides of each connection port. The stoppers and the locking parts are formed, but the number is naturally one, and the locking position along the height of the lid relative to the base (the height of the locking part) Is defined (see Patent Document 1).

  On the other hand, the wall surface that pipes the hot water supply pipe has a non-planar portion that is not a flat surface due to a partial slanted surface or a twisted surface, mainly due to problems in construction. When installing the above-mentioned bent pipe part and the attached protective cover of the branch pipe part on such a non-planar part, the base constituting the attached protective cover is plate-shaped as a whole. Since the bending rigidity, the torsional rigidity, etc. are relatively small, it can be installed and fixed by bending or twisting along the non-planar part within a predetermined range. However, the lid constituting the attached protective cover has a structure in which the oppositely arranged side plate portions are connected by the top plate portion, so that the bending rigidity, the torsional rigidity, etc. are large, and it follows the non-planar portion. It is difficult to be fixed by bending or twisting.

  As a result, the locked portion and the locking portion provided on both sides of the specific connection port among the plurality of connection ports cannot be locked, and only one locked portion and the locking portion are used. The lid body may be locked to the base. When the base and the lid are locked in such a state, there has been a problem that the lid is easily detached due to use over time or due to the action of some external force on the lid.

In addition, the two corners of the projecting corner and the entering corner of the building wall are not limited to being formed exactly perpendicular to each other, and may be slightly obtuse or acute due to construction problems. There is. Even in such a case, the locked parts that are formed on both sides of the base of the attached protective cover and the connection port of the lid body and are locked to each other, which protects the piping portions of the conventional protruding corners or entering corners Since the number of parts and the number of locking parts is one, as in the case of the attached protective cover for the bent pipe part and the branch pipe part described above, one of the two connection ports is locked. There is a case where the locked portion and the locking portion cannot be locked at the other connection port only by locking the portion and the locking portion. Even in this case, the lid constituting the attached protective cover is easily removed.

However, in the portion of the second connection port 25, the wall surface W ₁ is inclined along the piping direction Q ₁ so that the side of the interlocking portion A ₄ is slightly lowered, the first connection port 24a, along the direction connecting the 24b, but the wall W ₁ is inclined so that the side of the first connection port 24b becomes slightly lower, the pipe direction Q ₂ of the first connection port 24b It can be understood that the wall surface W ₁ is hardly inclined along the line. The base V ₁ of the protective cover C ₁ is fixed almost in close contact with the non-planar portion of the wall surface W ₁ that has been changed to the shape described above.

Therefore, in the portion of the first connection port 24a of the lid L _1, because hardly inclined wall surface W ₁ along the pipe direction Q ₂ (holding the partially plane) in FIG. 6 as shown, when the base V ₁ and oppositely disposed lid L ₁ is pressed against the base V _1, the engaging provided on both sides of the first connection port 24a of the lid L ₁ tip of the plate portion 27, by sliding along the upper inclined surface 11a of the base V ₁ of the connection port 2 of each of the locking provided on both sides projections 11 [FIG. 6 (b)], the each side plate portions 21 and 22 of the lid is elastically deformed slightly inward, through the locking hole 26b located on the front side of the opening surface 30 of the lid L _1, wherein each side plate portion 21 , 22 are restored to the original shape, so that the locked projections 11 on both sides of the base V ₁ are inserted into the locking holes 26a on the back side (the top plate portion 23 side) of the lid body L _1. And locked. In this state, the end surfaces of the side plate portions 21 and 22 of the lid L ₁ are close to the wall surface W ₁ with almost no gap. As shown in FIG. 6B, in the state where the locked protrusion 11 of the base V _{1 and} the locking hole 26a of the lid L ₁ are locked, the tip of the locking plate portion 27 is It has entered the hole 14. Note that the locking positions of the locked protrusions 11 and the locking holes 26a on both sides of the first connection port 24a are “regular locking positions”.

Further, in the portion of the second connection port 25 of the lid L _1, to the side of the first connection port 24b is slightly inclined to become lower along the pipe direction Q _1, as shown in FIG. 7 in the side of the first connection port 24a, the locking projection 11 of the base V ₁ was, but is locked to the inner side of the locking hole 26a of the lid L _1, the side of the first connection port 24b The locked protrusion 11 of the base V ₁ is locked in the locking hole 26b on the front side of the lid body L ₁ , and between the lower end surface of the first side plate portion 21 and the wall surface W ₁ , A slight gap 112 is formed. For this reason, in the portion of the second connection port 25 of the lid L ₁ , the top plate portion 23 of the lid L ₂ is slightly inclined with respect to the base plate portion 1 of the base V ₁ (the base is covered). The lid L ₂ is partially inclined with respect to the base V ₁ and covered). The locking positions of the locked projections 11 and the locking holes 26a, 26b on both sides of the second connection port 25 are “regular locking positions” on one side, but “normal locking positions” on the other side. It is locked at a position higher than the “stop position”.

Further, in the portion of the first connection port 24b of the lid L _1, although along the pipe direction Q ₂ hardly inclined, the pair of first connection port 24a, along the pipe direction Q ₁ connecting 24b Since the side of the first connection port 24b is inclined so as to be lowered, as shown in FIG. 8, each of the locked projections 11 of the base V ₁ is the front side (opening) of the lid L _1. It is locked in the locking hole 26b on the surface 30 side. Thus, between the side plates 21, 22 and the wall surface W ₁ to form the first connection port 24b of the lid L _1, any slight gap 112 is formed. Note that the locking positions of the locked protrusions 11 and the locking holes 26b on both sides of the first connection port 24b are locked at the same position higher than the “regular locking position”.

When the lid L ₁ is assembled to the base V ₁ fixed to the flat surface portion, the locked projections 11 and the locking holes are formed on both sides of all the three connection ports 24a, 24b, 25 in total. 26a is locked, and the “interlocking portions A _{1 to} A ₆ ” in total of six locations are all “regular locking positions”.

Thus, in a state where the lid L ₁ is covering the base V _1, each interlocking unit A ₁ to A ₆ of the six places engaged the base V ₁ and the lid L ₁ is In each case, along the direction perpendicular to the wall surface W ₁ (the height direction of the base V ₁ ), the locked protrusions 11 of the base V ₁ are each locking holes formed in the lid L _1. 26a, since the locking position by selecting one of the 26b is in configuration defined, in the non-planar portion of the wall surface W _1, fixed base to the non-planar portion of the wall surface W ₁ is slightly deformed while being covering the lid L ₁ with respect to V _1, in all of the interlocking portion a ₁ to a ₆ in total six, the locking projections 11 of the base V ₁ and the lid L ₁ The locking holes 26a and 26b can be locked. Therefore, the long-term use, or even when external force is applied to the lid L _1, the lid L ₁ with respect to the base V ₁ was not come off easily. The gap 112 formed between the end surfaces of the side plate portions 21 and 22 of the lid L ₁ and the wall surface W ₁ is closed with a caulking material or the like.

Also, the locking projection 11 of a total of three pairs of base V ₁ is, being locked respectively engaged in a total of three pairs of locking holes 26a lid L ₁ (26b), the lid L ₁ to the base V ₁ In order to release the locking in a state where the lid is covered, as shown in FIG. 6A, each outer side of the portion of the lid L _{1 where} the pair of left and right locking plates 27 are provided. When a force F is applied to the inner side, the side plate portions 21 and 22 (21 and 21) are elastically deformed inward as shown by two-dot chain lines in FIG. 22 (21, 21) engaging the pair together with the stop plate 27, and each spaced from the vertical wall portions 3 and 4 of the base V ₁ (3,3), locked projection 11 is engaged The locking is released by relatively escaping from the stop hole 26a (26b). In this state, when separating the lid L ₁ with respect to the base V _1, the lid L ₁ with respect to the base V ₁ is separated. Here, when force F is applied to the outside of the side plate portions 21 and 22 (21 and 21) inward to elastically deform the side plate portions 21 and 22 (21 and 21), it is excessively large. Even if the force F is applied, the standing wall portions 3 and 4 of the base V ₁ are arranged inside the end portions of the side plate portions 21 and 22 (21 and 21) on the opening surface 30 side. Since the ends of the portions 21 and 22 (21 and 21) on the opening surface 30 side abut against the standing wall portions 3 and 4 and prevent further elastic deformation, the unlocking operation is easy. Further, since the first connecting plate portion 28 connects the first side plate portion 21 or the second side plate portion 22 and the locking plate portion 27, the force F that elastically deforms the side plate portions 21 and 22 is directly applied. reportedly the locking plate 27, the engagement with locking release operation is facilitated, the locking hole 26a of the lid L _1, the engagement between the locking projection 11 of 26b and the base V ₁ twisted It is restricted from being formed, and the locking becomes firm.

However, even when the lid L ₄ interferes with the step portion 113 in the portion of the terminal protective cover C ₄ , If the terminal protective cover C ₄ of the fourth embodiment is used, the locked protrusion 75 of the base V ₄ and the lid L ₄ are locked at a slightly different position along the direction perpendicular to the wall surface W ₁ . since is is engaged with the hole 88a (88b), while said stepped portion 113 and the cover L ₄ interferes, it is possible to assemble by covering the lid L ₄ relative to the base V ₄ .

That is, as shown in FIGS. 18, 20 and 21, on the side opposite to the stepped portion 113, the locked protrusion 75 of the base V ₄ is engaged with the top plate portion 83 side of the lid L _4. Although locked to the stop hole 88a (locked to the “regular locking position”), on the stepped portion 113 side, the locked protrusion 75 of the base V ₄ is the opening surface of the lid L ₄ . 84 is locked in the locking hole 88b on the 84 side (locked at a position higher than the “normal locking position”), so that the stepped portion 113 remains interfering with the base V ₄ . The lid L ₄ can be assembled. As described above, even when the step portion 113 exists only on one side of the installation position of the protective cover C ₄ , the locked protrusions 75 on both sides of the connection port 82 are both connected to the locking holes 88 b. It is also possible to lock it. In other words, both sides of the connection port 82 can be locked at the same position higher than the “regular locking position”.

22 is a cross-sectional view taken along the line X ₁ -X ₁ of FIG. 18 in the case where the stepped portion 114 is present in the portion where the connecting side plate portion 81b of the lid L ₄ is disposed, and FIG. is X ₂ -X ₂ cross-sectional view taken along a line. As is apparent from FIGS. 22 and 23, the state connecting the side plate portion 81b of the stepped portion 114 and the cover L ₄ is by interfering, the opening surface 84 of the lid L ₄ is slightly inclined relative to the wall surface W ₁ In this case, the locking projections 75 of the base V ₄ are respectively locked in the locking holes 88b on the opening surface 84 side of the lid L ₄ , thereby connecting the stepped portion 114 and the lid L ₄ . The lid L ₄ can be assembled to the base V ₄ with the side plate portion 81b still interfering. That is, in this case, both sides of the connection port 82 are locked at the same position higher than the “regular locking position”, so that they remain on the base V ₄ while interfering with the stepped portion 114. On the other hand, the lid body L ₄ is assembled.

FIG. 24 is a perspective view showing a state in which both ends of the two straight pipe part protective covers C ₀ are connected by the protective cover C ₅ , and FIG. 25 shows a base V ₅ and a lid body constituting the protective cover C _5. is a perspective view of a separated state and L _5, FIG. 26 (a) is a cross-sectional view of a use state of the protective cover C _5, the (b) is an enlarged line Y-Y of the (a) It is sectional drawing.

Protective cover C ₅ is composed of a base V ₅ that is fixed to the wall surface W _1, a lid L ₅ assembled is covering on the base V _5. As shown in FIGS. 25 and 26, the base V ₅ has a plate-like standing wall portion 92 having a low height at the both ends in the width direction of the base plate portion 91 having a rectangular shape. Locked protrusions 93 are integrally formed on the inner sides of both longitudinal end portions of each standing wall portion 92, and a slip prevention groove 94 is formed on the inner end side of the locked protrusion 93 in each standing wall portion 92. It is the structure formed perpendicular | vertical with respect to. For this reason, a pair of locked projections 93 are provided opposite to the inner surface of the standing wall 92 at both ends in the longitudinal direction of the base V ₅ . In FIG. 25, reference numerals 95, 96, 97, and 98 denote a hole, a positioning plate portion, a reinforcing rib, and a screw insertion hole, respectively.

Further, the lid body L ₅ is opposed to the top plate portion 102 by connecting the side plate portions 101 opposed to each other at a predetermined interval by the top plate portion 102 and providing connection ports 103 at both ends in the longitudinal direction. In this configuration, the portion becomes the opening surface 104. At portions corresponding to the locked protrusions 93 of the base V ₅ in each side plate portion 101, locking protrusions 105 a and 105 b that are locked to the locked protrusions 93 are perpendicular to the opening surface 104. It is formed at predetermined intervals along the direction. That is, the locking plate portion 108 is connected to the inner side surface of the side plate portion 101 via the first and second connecting plate portions 106 and 107 on the inner side surfaces of both end portions in the longitudinal direction of each side plate portion 101. They are arranged in parallel to the inner surface with a predetermined interval therebetween. The first connecting plate portion 106 is provided in parallel with the connecting port 103 at the end on the back side of the locking plate portion 108 with respect to the connecting port 103, and the second connecting plate portion 107 has an opening surface. With reference to 104, it is provided in parallel with the opening surface 104 at the end on the back side (the top plate portion 102 side) of the locking plate portion 108. Therefore, the locking plate portion 108 and the side plate portion 101 are closed at the back end portion with respect to the connection port 103 and at the back end portion with respect to the opening surface 104, respectively. As described above, the front end and the front end with respect to the opening surface 104 are opened. Further, since the locking plate portion 108 is connected to the side plate portion 101 via the first and second connecting plate portions 106 and 107, the locking plate portion 108 is firmly attached to the side plate portion 101. Advantages resulting from this are the same as in the case of the protective cover C ₁ .

  Further, on the inner side surface of the locking plate portion 108 facing the side plate portion 101, two locking protrusions 105 a and 105 b are arranged at a predetermined interval along the direction perpendicular to the opening surface 104 with respect to the piping direction. It is provided in parallel. The locking protrusion 105b is formed at the end of the locking plate portion 108 on the opening surface 104 side.

Then, to protect the straight pipe portion protective cover C ₀ of the two accommodating protect the straight pipe portion P ₀ of the water supply hot water pipe P with a protective cover C ₅ is fixed to the base V ₅ to the wall surface W _1, respectively fixing the base V ₀ which straight pipe portion protective cover C ₀ on both sides of the base V _5, then the base V ₀ are arranged in a straight line across the base V _5, each base the straight pipe portion P ₀ of the water supply hot water pipe P by holding the tube holding portion 111 of the V _0, when each is Futafuta the lid L ₀ each base V _0, of the base V ₅ of the protective cover V ₅ The straight piping portion P ₀ is exposed only at the portion. In this state, when the lid L ₅ is covered with the base V ₅ , both ends of the lid L ₅ are in a state of covering the lid L ₀ of the straight pipe portion protective cover C ₀ (see FIG. 24).

Here, as shown in FIG. 26 (a), a portion lid L ₅ of the protective cover C ₅ is arranged, when projection 115 or the step 116, is present, base V the locking projection 93 of one of a pair of the locking projections 93 of the _5, two locking protrusions 105a formed on the one side plate portion 101 of the lid L _5, the open face 104 of 105b locked to the inner side of the engaging protrusion 105a with reference with (locked to "normal locking position"), the other of the locking projections 93, one side plate portion of the lid L ₅ Of the two locking ridges 105a and 105b formed on 101, the locking ridge 105b on the near side is locked with respect to the opening surface 104 (the same higher than the “normal locking position”). The other side plate portion 101 interferes with the protrusion 115 or the stepped portion 116. In the state, the lid body L ₅ is assembled to the base V ₅ . In this case as well, both sides of the connection port 103 can be locked at the same position higher than the “regular locking position”.

As described above, in the state in which the lid L ₅ is assembled to the base V ₅ , the first connecting plate portion 106 of the lid L ₅ has a slip prevention groove 94 formed in the standing wall portion 92 of the base V _5. Therefore, the lid body L ₅ does not shift in the piping direction with respect to the base V ₅ .

  In each of the first to fifth embodiments, one locked portion (locked protrusion) is provided on the base side, and the lid side is along a direction perpendicular to the opening surface. Since there are two locking portions (locking grooves or locking protrusions) that lock with the locked portion at a predetermined interval, the total number of locked portions and locking portions Is “3”, and the locking position of the locked portion of the base and the locking portion of the lid is selected at two different positions along the height direction of the base (direction perpendicular to the wall surface) There are advantages you can do. However, in the present invention, the number of the locked portions of the base and the number of the locking portions of the lid are provided corresponding to each other (for example, the number of the locked portions of the base is “2”, When the number of latching portions of the lid is “2”), the latching position of the latched portion of the base and the latching portion of the lid is set to the height direction of the base (direction perpendicular to the wall surface) A structure having a structure that can be selected at two different positions along the line is also included in the present invention. In the case of this example, the non-locked locked portion or the locking portion formed in a protruding shape interferes with the other member, and the locking between the original locked portion and the locking portion is hindered. In order to avoid this, it is necessary to design the locked portion or the locking portion formed in a protruding shape so as to be shifted along the piping direction.

  Further, the number of different locking positions along the height direction of the base (the direction perpendicular to the wall surface) between the locked portion of the base and the locking portion of the lid body is the same as that of each of the above-described first to third embodiments. 5 is “2”, but can be “3” or more.

  Moreover, in each said Examples 1-5, in the state in which the to-be-latched part and the latching | locking part of the cover body latched, and the base and the cover body were assembled | attached, of the side-plate part of a cover body The “connecting plate portion” used to integrally form the locking plate portion at a predetermined interval with respect to the inner side surface is the portion of the projection to be locked or the end portion of the standing wall portion formed on the base. By inserting into the formed anti-slip groove, in other words, by providing the anti-slip groove in the portion of the base where the “interlocking part” is formed, the base can be provided without any additional “slip prevention means”. There exists an advantage used as the structure by which a cover body does not shift | deviate along a piping direction with respect to a stand. However, since it is a structure often required in the piping structure that the lid body covered by the base does not shift in the piping direction with respect to the base, the "displacement prevention means" Naturally, a design separately provided in a portion other than the “interlocking portion” is also possible.

  In the present invention, the “slip prevention means” is not an indispensable configuration (although it is not necessary), but the locking plate portions 27, 85, and 108 are prevented from slipping as in the first, fourth, and fifth embodiments. By providing the connecting plate portions 28, 86 and 106 constituting the means, it is possible to prevent twisting between the locked portion of the base and the locking portion of the lid, and there is an advantage that it can be locked firmly.

Further, the protective covers C _{1 to} C ₅ of Examples ₁ to ₅ are all structures in which the locking positions in the “interlocking portions” on both sides of the connection port can be changed in the height direction. A structure in which the locking position of the “interlocking portion” on either side of the connection port can be changed in the height direction may be adopted.

  In Examples 1 to 5 described above, the protective cover for the hot water hot water pipe, which is one of the “wiring and piping materials”, has been described as an example. It can also be applied to the attached protective cover.
