Both ends of the narrow plate-shaped inner engaging portion E _{12 in} the longitudinal direction are reinforced with reinforcing ribs 29 from the end surface side of the inner side wall 23. The lower end of said pair of reinforcing ribs 28, at the start of engagement with the inner engaging portion E ₁₂ and the inner female engagement portion F ₁₂ of the base V ₁ of the lid L _1, by aligning both In order to facilitate the engagement, a guide claw 31 arranged so as to sandwich the engaged portion forming plate portion 7 of the base V ₁ is provided.

Then, in order to bend and dispose of the tubular body P by using the two straight protective covers C ₀ orthogonal to each other on the wall surface W and the protective cover connecting body C ₁ described above, the procedure is as follows. To do. First, the base V ₁ of the protective cover connecting body C ₁ is fixed to a predetermined position on the wall surface W via a screw 91, and then two bases V ₁ are fixed to each connection port 24 of the base V ₁ . Each base V ₀ of the straight protective cover C ₀ is connected in a state of being positioned in the width direction by the positioning piece 5, and the base V ₀ is fixed to the wall surface with screws. Next, a plurality of pipe bodies P are bundled and arranged on the bases V ₀ and V _{1 of} the two straight protective covers C ₀ and the protective cover connecting body C ₁ in a state of being greatly bent. After that, the base V ₀ of the straight protective cover C ₀ covers the lid L _0, and the straight portions of the plurality of tubular bodies P are accommodated and protected inside the straight protective cover C ₀ .

Finally, when the lid L ₁ is lightly pressed while dropping from directly above the base V ₁ of the protective cover connecting body C ₁ , each of the outer walls 22 of the lid L ₁ is lightly pressed at the outer standing wall 2 of the base V _1. By inserting the two insertion plate portions 26 provided near the connection port 24 into the two insertion grooves 8 of the base V ₁ , the two outer engaging portions E ₁₁ of the lid L ₁ are formed. By slightly bending the outer wall 22 inward, the outer engaging portions F ₁₁ formed inside the outer standing wall 2 of the base V ₁ are overcome, and the outer engaging portions of the lid L ₁ are obtained. E _11, together with the engaged overhang state with respect to each outer engaged portion F ₁₁ of the base V _1, one of the lid L ₁ inner engaging portion E ₁₂ is the lid L ₁ The inner side wall 23 is slightly bent outward, and each guide claw 31 at the end of the pair of reinforcing ribs 28 sandwiches the engaged portion forming plate portion 7 of the base V ₁ from both sides, so that the base V _In a state where the inner portion of the lid L ₁ is properly arranged with respect to the inner portion of ₁ , the inner engagement portion F ₁₂ of the base V ₁ is overcome and the inner engagement of the lid L ₁ is engaged. The joint portion E ₁₂ is engaged with the outer engaged portion F _{11 of the} base V _{1 in} a facing state. Two insertion plate portions 26 provided on the outer wall 22 of the lid L ₁ are inserted into the two insertion grooves 8 of the base V ₁ , and each outer engaging portion E ₁₁ of the lid L ₁ is inserted. but it is engaged by overhanging state with respect to each outer engaged portion F ₁₁ of the base V _1, the lid L ₁ with respect to the base V ₁ was in the direction of arrangement設経path R ₀ It does not shift along and the engaged state is stable. As described above, there are two engagement points between the base V ₁ and the lid L ₁ on the outside of the bend and one on the inside of the bend, and the engagement directions of the respective engagement points are all. The outer and inner engaging portions E ₁₁ and E ₁₂ of the lid L ₁ are arranged inside the bending, and the engaging directions of the engaging points are the same inside and outside the bending. Is a feature of the present invention.

Here, the aforementioned "respective outer engaging portion E ₁₁ of the lid L ₁ is engaged by an over hung on each outwardly engaged portions F ₁₁ of the base V _1" is a lid An outer engaging portion E ₁₁ provided inside the inner surface of the outer wall 22 of L _{1 so} as to face the inner surface at a predetermined distance, the outer engaging portion E ₁₁ and the lid L. _The base V ₁ and the lid L ₁ are assembled and assembled by engaging with the outer engaged portion F ₁₁ provided on the base V ₁ so as to be arranged between the inner side surface of the base _1. It is said that the engagement is released by bending the outer wall 22 of the lid L ₁ toward the side of the inner side wall 23.

As a result, as shown in FIG. 5, each connection port 24 of the lid L ₁ of the protective cover connection C ₁ covers the outside of the lid L ₀ of the straight protective cover C ₀ by a predetermined length. In this state, the lid L ₁ is integrally assembled to the base V ₁ of the protective cover connecting body C ₁ , and the bent portions of the plurality of pipes P are covered with the lid L ₁ . As shown in FIG. 5, of the outer standing wall 2 of the base V ₁ , between each straight outer standing wall portion 2b on both sides along the arrangement direction A and the outer wall 22 of the lid L ₁ the outer side. A bending space 32 that assists the bending deformation of the wall 22 is formed along the arrangement direction A. The two engagement points on the outside of the base V ₁ and the lid L ₁ are both arranged in the intermediate portion along the arrangement direction A of the bending space 32, so that the outer wall of the lid L ₁ is provided. The engaging portion is arranged at the position where the amount of bending deformation of 22 is maximum.

Then, when it becomes necessary to remove the lid L ₁ assembled to the base V ₁ of the protective cover connecting body C ₁ , the operator can perform the lid as shown in FIGS. 6 and 10 (a). When the portion of the bending space 32 of the outer wall 22 of L ₁ is pressed by the force G, the outer wall 22 of the portion of the bending space 32 bends largely inward, and the entire lid L ₁ faces the inside of the bending. By moving slightly, the engagement of the two engagement points on the outer side of the bend and the one engagement point on the inner side of the bend are simultaneously released, and in this state, as shown in FIG. 10 (b). When the entire lid L ₁ is rotated around the inner engaging portion in a direction away from the wall surface W, the engagement of the three engaging portions inside and outside is completely released, and the base is used. The lid L ₁ is removed with respect to V ₁ . In addition, in a state where only _one of the two engagement points on the outer side of the base V ₁ and the lid body L ₁ is disengaged as described above, the lid body L ₁ is engaged with the _one inner engagement point. the by rotating in the fulcrum, since the engagement of the outer of the other engagement portion is released in conjunction operator even without operating the both outer wall 22 at the same time, with respect to a base V ₁ The lid L ₁ can be easily removed.

Further, as shown in FIG. 10 (a), of the lid L ₁ a portion of the deformation space 32 of the outer wall 22 by pressing with a force G, bending the outer one of the bent inner two engagement portions It is also possible to separate the lid L ₁ from the base V ₁ by lifting the lid L ₁ upward as it is in a state where the engagements of the engagement points are simultaneously released. It should be noted that the engagement of the two engagement points on the outside of the bend is first disengaged without the engagement of the two engagement points on the outside of the bend and the one of the engagement points on the inside of the bend being disengaged at the same time. Thereafter, by rotating the lid L _1, when the engagement portion of the bent inner is released, during the rotation of the lid L _1, plate-like engaged portion of the lid L ₁ It is also possible to disengage one engaging portion inside the bending by slightly bending the forming plate portion 7 inward.

When a force G along the wall surface W is applied to the outer wall 22 of the lid L ₁ to disengage all the engaging portions, the engagement itself of each engaging portion is disengaged. In this state, the lid L ₁ is not separated from the base V ₁ unless the lid L ₁ is rotated or lifted upward. Therefore, even if a force G along the wall surface W unexpectedly acts on the lid L ₁ of the protective cover connecting body C ₁ during or after the piping work, the engagement of each engaging portion is released. in Runomi, when the force G is released, the restoring force of the outer wall 22 that is elastically deformed, each engagement portion, so as to return to the original engaged state with respect to the base V ₁ The lid L ₁ is not separated. In order to separate the lid L ₁ from the base V ₁ , in addition to disengaging all the engagement points, the lid L ₁ must be rotated or lifted. Since the lid L ₁ is not separated from the base V ₁ , such an unnatural force does not act unless it is conscious, and it is almost impossible to unexpectedly act on the lid L ₁ . After the base V ₁ and the lid L ₁ are assembled, the lid L ₁ is not separated.

The protective cover connecting body C ₂ of the _second embodiment is arranged so as to intersect with each other on the wall surface W of the building wall of the two straight protective covers C ₀ , similarly to the protective cover connecting body C _{1 of the} first embodiment. The only difference is that the crossing angle (θ) is (90 °) in Example 1 while it is obtuse angle (θ> 90 °) in Example 2, and the bending outer side is different. The structures of the engagement and disengagement of each of the two engagement points and the one inside the bending are the same. Therefore, the same parts as those in the first embodiment are designated by the same reference numerals, and the parts having the same functions although the dimensions or shapes are slightly different are given the same reference numerals with "'", and the description will be made mainly by illustration. To do.

The intersection angle (θ) of the two straight protective covers C ₀ is an obtuse angle, and the intersection angle of each of the outer and inner engaged portions F ₂₁ and F _{22 in} the orthogonal direction B is implemented. Since it is smaller than 45 ° in Example 1, a force G is applied to the outer wall 22'of the lid L ₂ by the operator's hand, and the outer wall 22' is flexed and deformed using the inner bending space 32'. When the two straight protective covers C ₀ are crossed at an angle (θ) of 90 °, the arrangement orthogonal direction B of the inner side wall 23'with respect to the bending deformation amount is compared with the first embodiment. Since the ratio of the amount of movement along the line is large, there is an advantage that the disengagement operation is easy.
