Description

In order to avoid interference with an overpassed body such as an existing straight protective duct and a protruding portion, the present invention covers each of the overpassed bodies and installs the respective straight protective covers installed on both sides of the overpassed body. The present invention relates to a straight protective cover connector for connection.
In the following description, the “straight protective duct” is one of the overpassed bodies, and the wiring / piping material already installed on the wall surface before the installation of the straight protective cover connector according to the present invention. The “straight protective cover” is a wiring connected via the “straight protective cover connector” according to the present invention disposed over the “straight protective duct”. -Refers to the housing material protection member.
In addition, the “front view” of the base and the lid constituting the straight protective cover connector means a direction view in which the overpass recess can be visually recognized with respect to the base, and the notch is visually recognized with respect to the lid. It refers to the possible direction.

  For example, Patent Document 1 discloses a base (base body) in which a recess is formed so as to be able to climb over (step over) a stepped portion (overpassed body) formed on a wall surface of a building, and the base. A lid body (cover body) provided with a closing plate part that covers the gap formed between the concave part and the step part of the base, and is installed with the step part interposed therebetween. A straight protective cover connector for connecting a straight protective cover is disclosed. In the closing plate portion, a plurality of breaking grooves are formed at predetermined intervals along a direction in which the straight protective cover connector crosses the stepped portion (passing direction). A device has been devised to eliminate the gap formed between the concave portion and the step portion of the base by breaking off the blocking plate portion.

  However, as described in paragraph “0051” of Patent Document 1, when the installation position of the base with respect to the stepped portion is shifted by more than a predetermined amount along the ride-over direction, the lid body is separated from the stepped portion. By the interference, the lid cannot be assembled to the base, and in the worst case, the construction is unavoidable. In other words, if the installation position of the base with respect to the stepped portion is not accurate along the overpass direction, the lid cannot be assembled to the base, and the accuracy of the installation position of the base is required. Therefore, the degree of freedom in construction was low (constraints were great).

JP 2012-369385 A

  Even if the installation position along the boarding direction of the base with respect to the overpassed body such as the straight protection duct and the protrusion installed on the wall surface is deviated from the normal position, the base The task is to enable the assembly of the lid to the base and to increase the degree of freedom in terms of construction.

  The invention of claim 1 for solving the above-mentioned problem comprises a base and a lid body which are assembled to each other to form an accommodation space for wiring and piping materials, and have a straight protective cover at both ends in the longitudinal direction. Each of the straight ports installed on both sides of the overpassed body is obtained by overcoming the overpassed body which is an obstruction such as a straight protective duct installed on the wall and protrusions. A straight protective cover connector for connecting a cover, wherein the base is connected to the base in a crossing direction at a contact part that contacts the wall surface so as to avoid the interference with the body to be crossed and to be able to get over. In the intermediate portion along which the raised portion is formed so as to be raised in a substantially inverted U shape in front view so as to be separated from the wall surface, a climbing recess is formed on the back side of the raised portion, and the lid body Connect the opposite side plate parts to the opposite side plate parts A plate portion, and is assembled to the base so as to cover substantially the whole of the base. Is fitted in a state where there is almost no gap, and the cutout portion is cut out by cutting out a portion of the cutout portion or the side plate portion having a size that fits in the overpass recess portion in the assembled state with the base. A notched portion forming scheduled portion is formed, and in order to enable the base and the lid to be assembled, an engaged portion provided on the base and the lid, respectively, and engaged with each other; and The engaging portion is characterized by having a structure that can maintain the engaged state of each other even if the base and the lid body relatively move along the overpass direction.

  According to the first aspect of the present invention, in the state in which the body to be overridden is fitted in the notch portion of the lid body without a gap, the overpass direction is within a range in which the notch portion of the lid body is accommodated in the overpass recess portion of the base. Even if the base and the lid move relative to each other, the engaged portion and the engaging portion that are respectively provided on the base and the lid and engage with each other can maintain the engaged state. Therefore, as long as the fixing position of the base with respect to the wall surface along the overpassing direction with respect to the overpassing body is displaced within the above range along the overpassing direction, the notch portion of the lid body is covered. The cover body can be assembled to the base in a state where the overpass body is fitted with no gap.

  For this reason, since a freedom degree generate | occur | produces within the said range in the fixed position along the boarding direction of the base with respect to a to-be-ridden body, the freedom degree of construction is raised. As a result, it is not necessary to redo the construction related to the fixing of the base to the wall surface, and the construction efficiency is improved.

  According to a second aspect of the present invention, in the first aspect of the present invention, in the assembled state of the base and the lid, there is almost no gap between the opening end surfaces of the side plates of the lid and the wall surface. In this state, the entire base is covered with a lid.

  According to the second aspect of the present invention, the end surface on the opening side of the lid is continuously free of any gap between both the overpassing body and the wall surface, that is, the “overall” state is realized. , Looks good.

  According to the present invention, as long as the fixed position of the base with respect to the wall surface along the overpassing direction with respect to the overpassing body is deviated within the allowable range along the overpassing direction, the overpassing body is a gap in the notch of the lid. Since the lid body can be assembled to the base in a state where it is fitted, there is a degree of freedom within the above range at a fixed position along the direction in which the base crosses over the body to be overridden. The degree of freedom is increased.

FIG.

  Hereinafter, the present invention will be described in more detail with reference to a plurality of examples.

First, the configuration of the straight protective cover connector C _{0 according to} the first embodiment will be described with reference to FIGS. 1 to 9, and then the wall surface W may be formed using the straight protective cover connector C _0. in a state in which over the straight protective duct D ₁ to D ₃ that are installed, the case of connecting the straight protective cover C disposed on both sides of the straight protective duct D ₁ to D _3.

As shown in FIG. 10, the three types of straight protective ducts D _{1 to} D ₃ over which the straight protective cover connector C _{0 of} Example 1 gets over have the same shape (similar shapes to each other) only in size, a base VD ₁ to VD _3, consists lid LD ₁ to Ld ₃ Metropolitan assembled integrally with the base VD ₁ to VD _3, the pipe P of different sizes to each base VD ₁ to VD _{3 11} in a state in which to P ₁₃ is accommodated and held, are covered by the lid LD ₁ ~LD _3.

The straight protective cover connector C ₀ includes a base V ₀ fixed to the wall surface W via a screw 91 and a lid L ₀ assembled integrally with the base V ₀ . The base V ₀ is bilaterally symmetric when viewed from the front (the left-right symmetric line is indicated by reference sign “KV ₀ ” in FIGS. 11 to 14), and is fixed in contact with the wall surface W. The abutting portion 1 that has been formed, a bulging portion 2 that is largely raised in a direction away from the wall surface W at the central portion in the longitudinal direction of the abutting portion 1 and has a substantially inverted U shape in front view, and the bulging portion 2 and a climbing recess 3 formed on the back surface side (side facing the wall surface W). The “right / left symmetry line” is also referred to as a “virtual center line”. Therefore, the contact part 1 is divided by the raised part 2. Overcoming the recess 3, therein, for straight protection duct D ₃ of the maximum size is fitted without clearance, the front shape of the ride-over recess 3, corresponds to the cross-sectional shape of the straight protective duct D ₃ of maximum size (It is the same as). For this reason, the surface of the inner surface of the overpass recess 3 that faces in the crossover direction Q is perpendicular to the wall surface W, and the outer surface of one or both of the existing straight protective ducts D _{1 to} D ₃ is applied. It is to contact, and has a placement posture positioning surface 3a to confirm the approximately orthogonal arrangement attitude of the straight protective cover fitting C ₀ for the straight protective duct D ₁ to D _3.

At both ends in the width direction of the abutting portion 1 and the raised portion 2, low standing wall portions 4 are continuously provided along the longitudinal direction. As shown clearly in FIGS. 6 and 7, the standing wall portion 4 is formed to protrude outward from both ends in the width direction of the abutting portion 1, and the standing wall portion 4, the abutting portion 1, As a step is formed between them, the flat surface portion of the back surface of the standing wall portion 4 is arranged away from the wall surface W and engages with an engagement protrusion 17 of the lid L ₀ described later. The engaging surface 5 is formed. The engaged surface 5 is formed on the base V ₀ so that the base V ₀ and the lid L ₀ can be relatively moved along the longitudinal direction of the base V ₀ in a state where they are assembled to each other. It is provided continuously along the longitudinal direction. Then, as shown in FIGS. 11 and 13, when the straight protective cover connector C ₀ gets over the straight protective ducts D ₁ and D ₂ of the minimum size or the intermediate size, the straight protective ducts D _1, D _2, only the upper arrangement attitude positioning surfaces 3a in arrangement of the base V ₀ in contact, in this state, since the lid L ₀ is assembled relative to the base V _0, base In the state where the left and right symmetry lines KV ₀ and KL _{0 of} V ₀ and the lid body L ₀ are shifted along the overpass direction Q of the straight protective ducts D ₁ and D ₂ of the straight protective cover connector C _0. The base V ₀ and the lid body L ₀ are assembled together. Further, as shown in FIG. 12, the minimum-sized straight protective duct D ₁ does not come into contact with any of the arrangement posture positioning surfaces 3a of the base V ₀ , and the straight protective duct D ₁ and the base in the case where the respective left and right symmetry line of the table V ₀ are shifted also, the left-right symmetry line KV _0, KL ₀ of the base V ₀ and the lid L ₀ is straight protection of the straight protective cover connector C ₀ The base V ₀ and the lid body L ₀ are assembled together in a state of being displaced along the overpass direction Q of the ducts D ₁ and D ₂ . For this reason, the base V ₀ and the lid body L ₀ can be relatively moved along the longitudinal direction (passing direction Q) of the base base V ₀ in a state where they are assembled to each other. engagement position engaged surfaces 5 of the base V ₀ against the engaging projection 17 of _0, it is necessary to continuously along the direction Q overcoming are countless exist.

On the other hand, if the base V ₀ and the lid L ₀ are relatively movable in the assembled state, when storing the straight protective cover connector C ₀ in the assembled state, one of the two is relatively the other. In order to prevent this, the stopper 6 is provided at an optimal position along the longitudinal direction of the planar engaged surface 5. The stoppers 6 are formed in two sets with a pair of stoppers 6 provided on the left and right engaged surfaces 5 of the base V ₀ as a set and sandwiching the notches H _{1 to} H ₃ . The amount of deviation between the left and right symmetry lines KV ₀ and KL ₀ of the base V ₀ and the lid L ₀ is the largest when the straight protective cover connector C ₀ gets over the minimum size of the straight protective duct D _1. The “optimum position” is a limit position where the maximum deviation amount (e ₁ ) can be secured, so that the base V ₀ and the lid L ₀ do not move unnecessarily. It is.

Here, the base V ₀ and the lid body L ₀ are relatively movable by a maximum deviation amount (e ₀ ) [see FIG. 4], but this maximum deviation amount (e ₀ ) is determined in the deviation direction ( By dividing into multiple pieces along the boarding direction Q), selecting the “movement range” according to the size of the straight protective ducts D _{1 to} D ₃ , and assembling the base V ₀ and the lid L ₀ In addition, the maximum relative displacement between the base V ₀ and the lid L ₀ during construction can be reduced, and the base V ₀ and the lid L ₀ greatly deviate when the straight protective cover connector C ₀ is stored. Can prevent the problem.

When the lid body L ₀ is assembled to the base V _{0 of the} straight protective cover connector C ₀ , the portion of the outer surface of the standing wall portion 4 where the engaging protrusion 17 of the lid body L ₀ comes into sliding contact is the sliding contact portion. Is formed on the inclined surface 4a. Note that in FIG. 8 and FIG. 9, 7 shows an insertion hole of the screw 91 formed on the abutment 1, 8, connecting port below the longitudinal ends of the straight protective cover fitting C ₀ J for positioning in the width direction of the base VC of connected straight protective cover C to show the positioning plate formed at both ends in the longitudinal direction of the abutment 1, 9, the base V ₀ The double-sided tape sticking recessed part provided in the back surface of the contact part 1 is shown.

Next, FIG. 1, with reference to FIGS. 6 to 8, will be described lid L ₀ to be assembled on the base V ₀ which straight protective cover fitting C _0. Similarly to the base V ₀ , the lid body L ₀ has a left-right symmetrical shape in front view (the left-right symmetry line is indicated by the symbol “KL ₀ ” in FIGS. 8 and 11 to 14). ] The bulging sides of both side plate portions 11 arranged in parallel with each other at an interval corresponding to the width of the contact portion 1 of the base V ₀ are connected by the top plate portion 12 and are opposite to the top plate portion 12. The assembly opening 13 is formed on the side. That is, the lid L ₀ is to correspond to a substantially inverted U-shaped ridge portion 2 on the side away from the wall surface W in the center portion in the longitudinal direction of the base V ₀ is formed, the lid L ₀ The portion corresponding to the raised portion 2 of the base V ₀ is a bulging portion 14 that is greatly bulged toward the side away from the wall surface W.

A total of three types of notch portions H _{1 to} H ₃ (FIG. 1) having a shape in which three types of straight protective ducts D _{1 to} D ₃ having different sizes are fitted without gaps in the center portion in the longitudinal direction of both side plate portions 11. 8, FIG. 11 to FIG. 14) can be formed. That is, the notch H ₁ corresponding to the minimum-sized straight protective duct D ₁ is formed in advance, and the remaining two notches H ₂ and H ₃ are portions of the thin portions 15 and 16. The side plate portion 11 is formed by cutting out a part thereof. As shown in FIG. 8, a total of three types of notches H _{1 to} H ₃ have a common bottom and are arranged symmetrically with respect to the symmetric line KL ₀ of the lid L ₀ . In relation to the boarding recess 3 of the base V ₀ , the maximum size notch H ₃ is sized to fit within the boarding recess 3. The end face 11a formed on the side of the assembly opening 13 of the side plate portions 11 of the lid L ₀ is in the state assembled with the lid L ₀ with respect to the base V ₀ which is fixed to the wall W, the wall surface W It is formed in a straight shape so as to be close to each other without a gap.

A total of four sets of engaging protrusions are formed on the inner surface of the both side plate portions 11 of the lid body L _{0 so} as to be engaged with the engaged surface 5 of the base V _0. 17 is formed. A total of four sets of engaging projections 17 are arranged on both sides of the notch H ₁ . Since both side plate portions 11 constituting the lid body L ₀ can be elastically deformed, the lid body L ₀ is placed on the base V ₀ fixed to the wall surface W, as shown in FIGS. When pressed by way, when the four pairs of the engaging projections 17 move over sliding contact with the inclined surface 4a of the outer wall part 4 of the base V _0, elastically deformable side plate portions 11 is slightly outwardly After that, the both side plate portions 11 are restored to the original shape, and the engagement protrusions 17 of the lid body L ₀ are planar engagement surfaces 5 formed on the back surface of the standing wall portion 4 of the base V _0. The lid body L ₀ is integrally assembled to the base V ₀ . In this state, the lid L ₀ can be moved in the longitudinal direction with respect to the base V ₀ fixed to the wall surface W as described above. However, when the lid body L ₀ is assembled to the base V ₀ fixed to the wall surface W in a state of overcoming the existing straight protective ducts D _{1 to} D _{3 as} will be described later, the lid body L _In a state in which the longitudinal protection ducts D _{1 to} D ₃ installed on the wall surface W are partially fitted in the notches H _{1 to} H ₃ formed in the both side plate portions 11 of _0. , since the lid L ₀ with respect to the base V ₀ it is assembled, in assembled state, the lid L ₀ does not move relative to the base V _0. In addition, by assembling the base V ₀ and the lid body L ₀ , the space formed between them connects the pipes P piped on both sides with the straight protective ducts D _{1 to} D ₃ interposed therebetween. It becomes the accommodation space N of the connecting pipe 93.

Further, by attaching the lid L ₀ to the base V ₀ , straight protection is provided at both ends in the longitudinal direction (from the point of going over the straight protective ducts D _{1 to} D ₃ , the crossing direction Q). A connection port J connected to the end of the cover C is formed. As shown in FIG. 1, the connection port J is formed at the end of the connection port adjustment unit 18 while leaving the tapered connection port adjustment unit 18. It should be noted that by removing the connection port adjusting portion 18, another connection port J ′ larger than the connection port J is formed at both ends in the longitudinal direction (passing direction Q) of the lid L ₀ (see FIG. 14). Is formed.

Next, referring to FIG. 1 to FIG. 7 and FIG. 10 to FIG. 14, the straight shape installed horizontally on the wall surface W using the above-described straight protective cover connector C ₀ in the renovation work or the like. overcame protection duct D ₁ to D _3, moreover, the straight-like protective duct D ₁ to D ₃ and is substantially perpendicular, will be described operation of connecting the straight protective cover C of two arranged on both sides .

First, with reference to FIG. 1 to FIG. 5 and FIG. 11, the case where the straight protective cover connector C ₀ is installed over the minimum size straight protective duct D ₁ installed on the wall surface will be described. First, as shown in FIGS. 1 and FIG. 11 (a), the the existing straight protection duct D ₁ of the which are horizontally arranged perpendicular to the wall surface W, overcoming the base V ₀ which straight protective cover connector C ₀ The base V ₀ is brought into contact with the wall surface W so as to be accommodated in the recess 3, and the upper side surface of the straight protective duct D ₁ is brought into contact with one arrangement posture positioning surface 3 a of the base V _0. Let Arrangement attitude positioning surface 3a which is formed opposite to climb over along the direction Q overcoming the inner surface of the recess 3 of the base V _0, in a state where the base V ₀ is placed on the wall surface W, with respect to the wall surface W since vertical, as described above, the upper side of the straight protective duct D ₁ of the smallest size, when brought into contact with one of the arrangement attitude positioning surface 3a of the base V _0, the base V ₀ is is disposed substantially perpendicular to the straight protective duct D ₁ [intersection angle between the straight protective duct D ₁ and the base V ₀ (theta) is 90 °] is the base V ₀ itself , They are arranged so as to be shifted in the boarding direction Q with respect to the straight protective duct D ₁ (the left-right symmetric line KV ₀ of the base V ₀ is shifted from the left-right symmetric line of the straight protective duct D _1. Arranged). In this state, the base V ₀ is fixed to the wall surface W via a plurality of screws 91.

As shown in FIG. 1, at both ends of the base board V ₀ of the straight protective cover connector C ₀ which is fixed to the wall surface W substantially orthogonally to the existing straight protective duct D ₁ , in both ends of the boarding direction Q. After connecting the base VCs of the straight protective covers C, the new pipes P are accommodated in the accommodation paths of the bases VC, and the straight pipes installed over the straight protective ducts D ₁ are installed. By housing the bent connection pipe 93 on the base V _{0 of the} protective cover connector C ₀ , the two newly installed pipes P are connected via the connection pipe 93 described above. As a result, the two newly installed pipes P that are piped on both sides of the existing straight protective duct D ₁ are accommodated in the straight protective cover connector C ₀ arranged over the straight protective duct D _1. The connection pipe 93 is connected. In FIG. 1, reference numeral 97 denotes a pipe joint that connects the newly installed pipe P and the connecting pipe 93.

Then, after assembling the lid LC on the base VC of each straight protective cover C, the base V _{0 of} the straight protective cover connector C ₀ installed over the existing straight protective duct D ₁ is used. When the lid body L ₀ is assembled, as shown in FIG. 2 to FIG. 5 and FIG. 11, the minimum-sized straight protective duct D ₁ is fitted into the notch H ₁ of the lid body L ₀ without a gap. That is, even if the base V ₀ of the straight protective cover connector C ₀ is arranged to be shifted along the ride-over direction Q with respect to the minimum-sized straight protective duct D ₁ , the lid L ₀ is Arranged with respect to the straight protection duct D ₁ without shifting along the overpass direction Q, that is, in a state where the left / right symmetry line KL ₀ of the lid L _{0 and} the right / left symmetry line of the straight protection duct D ₁ are matched. Is done. As a result, the left-right symmetry line KV ₀ of the base V ₀ which straight protective cover fitting C _0, a left-right symmetry line KL ₀ of the lid L ₀ is, get over the amount of displacement along a direction Q (e ₁₎ only In a shifted state, they are engaged with each other and assembled together. As described above, this is possible because the base V ₀ and the lid body L ₀ are assembled with each other along the longitudinal direction (passing direction Q) of the base V _0. Since the relative movement is possible, that is, there are an infinite number of engagement positions of the engaged surface 5 of the base V ₀ with respect to the engagement protrusion 17 of the lid L ₀ along the overpass direction Q. It is.

Thus, it is arranged base V ₀ which straight protective cover connector C ₀ is shifted along the climb over the direction Q of the straight protective duct D ₁ relative to the straight protective duct D _1, lid With the straight protective duct D ₁ fitted in the notch H ₁ of the body L ₀ without any gap, the lid L ₀ can be assembled without any trouble to the base V ₀ that is displaced. becomes so gone constraint construction, i.e., increasing the degree of freedom in construction, in a state where the straight protective cover connector C ₀ gets over the straight protective duct D _1, both sides of the straight protective duct D ₁ The operation of connecting the two pipes P arranged at the position with the straight protective cover connector C ₀ can be performed quickly. In other words, be arranged offset along a direction Q get over the base V ₀ which straight protective cover fitting C ₀ relative straight protection duct D ₁ is installed obstacle on the wall, the work bookmarks There is an advantage that the next work can be performed as it is without performing repair (reinstallation of the base V ₀ ).

Further, the end face 11a of the straight protective duct D ₁ to the cutout portion H ₁ of the lid L ₀ is with is fitted without any gap, is formed on the side of the assembly opening 13 of the side plate portions 11 of the lid L ₀ is in a state assembled with the lid L ₀ with respect to the base V ₀ which is fixed to the wall surface W, so as to be close in the absence of a gap to the wall surface W, since it is formed in a straight shape, the base V ₀ the lid L ₀ in a state assembled together, the total end surface including the end face of the cutout portion H ₁ of the lid L ₀ is the outer surface of the straight protective duct D _1, and close in the absence of a gap to the wall surface W Since the state, that is, the state of “overall” of the lid L ₀ , the internal bases V ₀ are not visually recognized at all, and the appearance is improved.

The inner surface near the opening of the connection port adjusting portion 18 that forms the connection port J is gradually narrowed from the base end toward the free end (opening side) so as to be tapered in a longitudinal sectional view. Therefore, a plurality of pieces (two pieces) having different projecting lengths for bringing the pipe P ₁₁ into contact with the outer peripheral surface of the end portion of the pipe P ₁₁ inserted in the connection port J and stabilizing the connection state of the pipe P _11. ) Tube contact protrusion 21 (see FIGS. 4 and 5).

Further, the arrangement of the base V ₀ of the straight protective cover connector C ₀ with respect to the straight protective duct D ₁ described above is such that one of the pair of arrangement posture positioning surfaces 3a on the inner surface of the overpass recess 3 is connected to the straight protective duct. Although it is in contact with the outer surface of D ₁ , as shown in FIG. 12, the straight protective duct D ₁ is not attached to any of the pair of arrangement posture positioning surfaces 3 a of the straight protective cover connector C _0. It is also possible to arrange the base V ₀ so as to get over the straight protective duct D ₁ so as to be in contact. In this case, the shift amount (e ₂ ) of the respective symmetrical lines KV ₀ and KL ₀ between the base V ₀ of the straight protective cover connector C ₀ and the lid body L ₀ is based on the shift amount (e ₁ ). (E ₁ > e ₂ ). In this arrangement example, the base V ₀ of the straight protective cover connector C ₀ is not in contact with a reference portion (arrangement posture positioning surface 3 a) for orthogonal arrangement with respect to the straight protective duct D ₁ . Therefore, it is necessary to ensure the orthogonal arrangement by some means such as a ruled line (not shown) on the wall surface W.

Further, when the straight protective cover connector C ₀ is disposed over the intermediate size straight protective duct D _2, as is apparent from the comparison between FIG. 11 and FIG. 13, the straight protective cover connector C _0. The amount of relative movement between the base V ₀ and the lid body L ₀ , that is, the amount of deviation (e ₃ ) between the two is compared with the amount of deviation (e ₁ ) when getting over the minimum-sized straight protective duct D _1. The other points are the same except that the small (e ₁ > e ₃ ) point is different and that the substantially perpendicular arrangement with respect to the straight protective duct D ₂ is possible.

When the straight protective cover connector C ₀ is arranged over the maximum size of the straight protective duct D _3, as shown in FIG. 14, the maximum is provided in the ride over recess 3 provided on the base V _0. Since the straight protective duct D ₃ is fitted into the notch H ₃ having a size without a gap, the base V ₀ is not displaced from the straight protective duct D ₃ . Therefore, there is no deviation amount between the left and right symmetrical lines KV ₀ and KL ₀ in the state in which the lid L ₀ is assembled to the base V ₀ of the straight protective cover connector C ₀ . In FIG. 14, J ′ is formed at both ends in the longitudinal direction of the lid L ₀ by cutting away the connection port adjusting portion 18 in order to enable connection of a pipe having a diameter larger than that of the new pipe P. The connected port is shown.

Next, with reference to FIGS. 15 to 17, only a portion different from the straight protective cover connector C ₀ will be described with respect to the straight protective cover connector C ₀ ′ of the second embodiment of the present invention. The existing obstacles provided on the wall surface W and over which the straight protective cover connector C ₀ should get over are the straight protective ducts D _{1 to} D ₃ in the _first embodiment, whereas in the second embodiment, The difference is that it is a parting plate B having a square cross section. Correspondingly, in the straight protective cover connector C ₀ ′ of Example 2, the notches H _B provided on the both side plates 11 of the lid L ₀ ′ are in the cross section of the parting plate B. The only difference is the corresponding square shape.

For this reason, a straight protective cover connector vertically disposed on the side surface of the parting plate B installed horizontally on the wall surface W in the same manner as when the obstacle is the straight protective ducts D _{1 to} D _3. With one arrangement posture positioning surface 3a of the boarding / recessing recess 3 of the base V ₀ of C ₀ ′ in contact with the parting plate B, a plurality of the bases V ₀ are arranged substantially orthogonally. When the base V ₀ is fixed to the wall surface W via the screws 91, the base V ₀ is installed on the wall surface over the parting plate B. Then, after the connection of two pipes P to be piped to either side of the parting plate B in the connection tube 93, with the fitting the parting plate B to the notch H _B of the lid L ₀ ', the base 'When assembled integrally, base V ₀ and the lid L _0' the lid L ₀ with respect to V ₀ the symmetry line KV _0, KL ₀ 'is a deviation of (e ₄₎ and being shifted by Become.

In the above-described embodiment, the straight protective ducts D _{1 to} D ₃ or the parting plate B, which are overpassed bodies (obstacles), are overcome and hit the outer surface of the straight protective ducts D _{1 to} D ₃ or the parting plate B. arrangement attitude positioning surface 3a of the base V ₀ in contact is not formed in a planar shape over the entire width of the base V _0, the stability of the contact state is increased. However, the arrangement attitude positioning surface 3a of the base V _0, by abutting on the outer surface of the straight protective duct D ₁ to D ₃ or parting plate B, the straight protective duct D ₁ to D ₃ or parting plate B since the base V ₀ is sufficient if arranged substantially perpendicular to, the arrangement attitude positioning surface 3a of the base V _0, a plurality of abutment projections provided along the width direction of the base V ₀ It is also possible to configure such that the tips of the plurality of abutting projections abut on the outer surfaces of the straight protective ducts D _{1 to} D ₃ or the parting plate B.

  Further, in the present invention, the size and type of the straight protective duct and the parting plate that are the overpassing body are formed by forming the overpassing recess of the base constituting the straight protective cover connector larger than the overpassing body. Alternatively, the position where the base and the lid have moved relative to each other even when the boarding body is smaller than the boarding recess of the base (different positions). However, because the notch of the lid abuts the overpassed body, the relative movement of the lid with respect to the base is restricted. There is no need to fix the base in consideration, and workability (the degree of freedom of the base mounting plate) is improved.

In the above construction example, the ride-over body wall (obstacle) a is straight protection duct D ₁ to D ₃ or parting plate B is mounted horizontally, the straight by approximately perpendicular to the obstacle In this example, the protective cover connector C ₀ , C ₀ ′ is installed vertically, but when the obstacle is installed vertically on the wall surface W, the straight protective cover connector C ₀ , C ₀ ′ is horizontal. Installed. Furthermore, an obstacle may be installed not only on a vertical wall surface but also on a horizontal plane, and a straight protective cover connector may be installed over the obstacle.
