  Next, the protective cover 100 in a state where the covering body 120 is assembled to the base 110 will be described with reference to FIGS. 9 to 15. FIG. 9 is a schematic perspective view of the protective cover 100 according to the embodiment of the present invention. FIG. 10 is a rear view of the protective cover 100. FIG. 11 is a bottom view of the protective cover 100. 12 to 15 are sectional views of the protective cover 100 taken along DD, EE, FF, and GG.

  In the protective cover 100, the base 110 is detachably assembled to the cover 120 while the base 110 is accommodated inside the peripheral wall 121 of the cover 120. The base portion 111 of the base 110 extends between the pair of side wall portions 124 below the flange portion 125 of the peripheral wall 121 and in the vicinity of the opening 123. Further, the contact surface of the base portion 110 is disposed on substantially the same plane as the end surface of the opening 122 of the covering 120. And it extends so that the inner surface of a pair of side wall part 124 of the surrounding wall 121 may oppose with respect to a pair of standing wall part 112 outer surface of the base 110, and the extended part 113 outer surface. The standing wall portion 112 is disposed below the circular accommodation space of the flange portion 125. On the other hand, a part of the extended portion 113 extends into the accommodation space of the flange portion 125. In particular, the accommodation recess 117 of the extension portion 113 overlaps the accommodation space of the flange portion 125, and the positioning portion 118 of the extension portion 113 is positioned adjacent to the outer periphery of the accommodation space. That is, the positioning portion 118 can be brought into contact with the outer peripheral surface of the decorative cover 13 while the decorative cover 13 accommodated in the flange portion 125 is accommodated in the accommodating recess 117. Further, as shown in FIG. 13, the outer surface of the standing wall portion 112 and the inner surface of the side wall portion 124 are separated from each other, and a gap is formed between them. This gap secures the allowance for inward bending of the pair of side wall portions 124. On the other hand, as shown in FIG. 15, almost no gap is formed between the outer surface of the extending portion 113 and the inner surface of the side wall portion 124. This is because the extended portion 113 is bent so as to swell outward with respect to the standing wall portion 112 as described above.

  In the protective cover 100, a first engagement relationship is formed between the first engagement portion 126 and the first engaged portion 115, and between the second engagement portion 127 and the second engaged portion 116. By forming the second engagement relationship, the covering 120 and the base 110 are firmly coupled. Hereinafter, each engagement relationship will be described in detail.

  As shown in FIGS. 12, 13, and 14, in the first engagement relationship between the first engaging portion 126 and the first engaged portion 115, the standing wall portion is provided between the inner surface of the side wall portion 124 and the refractive piece 126b. 112 The tip has entered. Then, the partition wall 126d passes through the slit 115b, and the engaging claw 115a is fitted into the engagement hole 126c from the inside of the side wall portion 124, whereby the relative movement between the standing wall portion 112 and the side wall portion 124 is restricted. As a result, the standing wall portion 112 of the base 110 and the peripheral wall 121 of the covering 120 are fixed on the lower side of the flange portion 125 (near the periphery of the wall hole 11). When the pair of side wall portions 124 are bent and deformed inward, the locking claws 115a come out of the engagement holes 126c, and the first engagement between the first engagement portion 126 and the first engaged portion 115 is performed. The joint relationship is released. In particular, the first engagement is achieved by retreating (separating) the covering body 120 from the base 110 so that the locking claw 115a is detached from the engagement hole 126c and the partition wall 126d comes out of the slit 115b. You can break the relationship completely.

  As shown in FIGS. 12 and 15, in the second engagement relationship between the second engagement portion 127 and the second engaged portion 116, the second engagement portion 127 protruding inside the side wall portion 124 extends. It arrange | positions at the arrangement | positioning space 116b of the installation part 113 front-end | tip, and the engagement surface (vertical surface) of the 2nd engagement part 127 has opposed the latching edge 116a. The engaging surface of the second engaging portion 127 is substantially in contact with the locking end edge 116a. That is, when the second engaging portion 127 is locked to the locking end edge 116a, the side wall portion 124 (second engaging portion 127) moves in the standing direction (right direction in FIG. 12) of the standing wall portion 112. Is regulated. On the other hand, since the upper portion of the arrangement space 116c is opened by the opening portion 116c, the extension portion 111 of the side wall portion 124 (second engagement portion 127) is allowed to move in the extending direction (upward in FIG. 12). Has been. Therefore, in a state where the first engagement relationship is released, the second engagement portion 127 can be detached from the arrangement space 116c via the opening portion 116c, and the second engagement relationship can be released.

  That is, in the protective cover 100 of this embodiment, the side wall portion 124 is fixed to the standing wall portion 112 at the lower portion of the flange portion 125 (near the periphery of the wall hole 12) by the first engaging portion 126 and the first engaged portion 115. At the same time, the second engaging portion 127 and the second engaged portion 116 cause the side wall portion 124 to be locked to the extending portion 113 at the substantially central portion of the flange portion 125, so that the covering body 120 moves in the separation direction. Be regulated. As described above, the coupling between the base 110 and the covering body 120 can be firmly maintained by the two engagement relationships separated in the vertical direction.

  Subsequently, referring to FIG. 16 to FIG. 19, the protective cover 100 is installed on the wall 11 and the wall hole 12, and the bent portion of the wiring / pipe material 14 disposed through the wall hole 12 is A method for constructing the protective structure 10 protected by the protective cover 100 will be described. In the present embodiment, a ring-shaped decorative cover 13 is fixed to the periphery of the wall hole 12, and the decorative cover 13 protrudes from the wall surface with a predetermined thickness. The protective cover 100 and the decorative cover 13 constitute a protective device for the wiring / piping material 14. However, the decorative cover may optionally be omitted in the present invention.

  First, as shown in FIG. 16, the base 110 is fixed to the wall 11. Specifically, the abutment surface (back surface) of the base 111 is directed to the wall surface in the vicinity of the periphery of the wall hole 12, and the fixing position of the base 111 is aligned. Preferably, the decorative cover 13 is disposed in the housing recess 117 of the extending portion 113, and the fixing position of the base 111 is determined so that the outer peripheral surface of the decorative cover 13 is brought into contact with the positioning portion 118. After determining the fixing position, the base 110 is fixed to the wall 11 by passing a screw through the fixing hole 114 formed in the base 111.

  As shown in FIGS. 17 and 18, in a state where the base 111 is fixed to the wall 11, the base 111 and the standing wall 112 are fixed in the vicinity of the peripheral edge of the wall hole 12 and the decorative cover 13, and the extension 113 is on the wall hole 12 side. A part thereof (a tip portion in the extending direction) extends to the front surface of the wall hole 12. The decorative cover 13 is disposed in the housing recess 117 of the extending portion 113, and the positioning portion 118 is in contact with the outer peripheral surface of the decorative cover 13.

  Next, as shown in FIG. 19, the covering 120 is assembled to the base 110. Specifically, the covering body 120 is gripped from the front of the wall hole 12, the covering body 120 is placed on the base 110 so as to accommodate the decorative cover 13 in the flange portion 125, and the covering body 120 is pressed against the base 110 from the front. To do. At this time, when the second engagement portion 127 protruding from the inner surface of the peripheral wall 121 contacts the front end edge of the extension portion 113, the front end edge of the extension portion 113 gets over the inclined surface of the second engagement portion 127 and the extension portion 113. Is bent inward (or the side wall 124 is bent outward), and the second engaging portion 127 slides on the outer surface of the extending portion 113. When the second engaged portion 116 is reached, the extended portion 113 that is bent and deformed inward is elastically restored, the second engaging portion 127 is arranged in the arrangement space 116b, and the second engaging portion 127 is engaged. The surface and the locking edge 116a face each other so as to be engageable with each other. On the other hand, almost simultaneously with the second engagement portion 127 sliding on the outer surface of the extending portion 113, the partition wall 126d of the first engagement portion 126 on the inner surface of the peripheral wall 121 enters the slit 115b opened at the tip of the standing wall portion 112, and is locked. The claw 115a comes into contact with the refractive piece 126b. Through the inclined surface of the locking claw 115a, the standing wall 112 is bent and deformed outward (or the side wall 124 is bent and deformed inward), and as a result, the locking claw 115a is guided to the engagement hole 126c. That is, until the first engaging portion 126 is engaged with the first engaged portion 115 and the second engaging portion 127 is engaged with the second engaged portion 116, the covering 120 is attached to the base 110. By pressing the cover 120, the covering 120 can be firmly assembled to the base 110. And the protection structure 10 shown in FIG.20 and FIG.21 is constructed | assembled by arrange | positioning the wiring and piping material 14 through the wall hole 12. FIG. In addition, the arrangement | positioning process of the wiring and piping material 14 may be performed in any step of an above-described process according to a condition.

  Subsequently, a method of disassembling the protective cover 100 by removing the covering 120 from the base 110 will be described with reference to FIGS. 22 and 23.

  First, in order to remove the covering 120 from the base 110, the first engagement relationship between the first engaging portion 126 and the first engaged portion 115 is released. Specifically, as shown in FIG. 22, the pair of side wall portions 124 of the covering body 120 are pressed inward (in a direction close to each other) to bend and deform, thereby causing the engagement holes 126 c of the first engagement portion 126 to be bent. Moves inward, and the locking claw 115a is detached from the engaging hole 126c. Further, by retracting the cover 120 from the wall hole 12, the partition wall 126d is detached from the slit 115b, and the first engagement relationship is completely released. In addition, since the first engaged portion 115 is formed on the front end side of the standing portion 113 in the standing direction, the distance for retracting the covering 120 from the wall hole 12 is relatively small.

  After releasing the first engagement relationship, the covering body 120 is moved so that the second engagement portion 127 is detached from the arrangement space 116b of the second engaged portion 116 in order to release the second engagement relationship. Hold and operate. In particular, when the lower portion of the peripheral wall 121 is retracted so as to separate the partition wall 126d from the slit 115b, the second engagement portion 127 rotates in the arrangement space 116b as shown in FIG. Specifically, the lower portion (base 111 side) portion of the second engagement portion 127 tilts in a direction away from the wall 11. At this time, the lower end edge of the engaging surface of the second engaging portion 127 presses the locking end edge 116a of the second engaged portion 116 in a direction away from the wall 11, and the extending portion 113 is in front of the wall 11. Slightly deforms to the side. In this state, the cover body 120 is slid upward along the wall surface, so that the second engagement portion 127 moves along the extending direction of the extending portion 113, and the arrangement space 116b via the opening portion 116c. Leave. That is, since the second locked portion 116 is provided at the distal end of the extending portion 113 farthest from the fixing portion 114 (base portion 111), the extending portion 113 is released along with the release of the first engagement relationship. Is easily bent and deformed in the direction away from the wall 11, and the second engagement portion 127 is easily detached from the opening portion 116c. As a result, both the first and second engagement relationships are released, and the covering 120 can be removed from the base 110.

  Hereinafter, the operation and effect of the protective cover 100 according to the embodiment of the present invention will be described.

  According to the protective cover 100 of the present embodiment, the first engaged portion 115 formed on the standing wall portion 112 of the base 110 and the first surface formed on the inner surfaces of the pair of side wall portions 124 of the peripheral wall 121 of the covering body 120. When the 1 engaging portion 126 is engaged, the relative movement between the standing wall portion 112 and the side wall portion 124 is restricted. By the first engagement relationship between the first engagement portion 126 and the first engaged portion 115, the standing wall portion 112 of the base 110 and the peripheral wall 121 of the covering body 120 are fixed in the vicinity of the peripheral edge of the wall hole 12.

Further, the second engaged portion 116 formed on the extending portion 113 of the base 110 and the second engaging portion 127 formed on the inner surfaces of the pair of side wall portions 124 of the peripheral wall 121 of the covering body 120 are engaged. By combining, movement of the standing wall portion 112 of the side wall 124 in the standing direction is restricted. Due to the second engagement relationship between the second engagement portion 127 and the second engaged portion 116, the peripheral wall 121 is locked by the extending portion 113 of the base 110, and the covering 120 is separated from the wall surface. Is regulated. That is, in the vicinity of the periphery of the wall hole 12, a first engagement relationship that restricts relative movement between the standing wall portion 112 and the side wall portion 124 is formed, and at a position separated from the first engagement relationship toward the wall hole 12 side. Then, a second engagement relationship that restricts the separation from the wall surface of the covering 120 is formed. Accordingly, the first and second engagement relationships at different positions cooperate to allow the covering 120 to be firmly attached to the base 110 fixed to the wall 11. On the other hand, the first engaging portion 126 and the first engaged portion 115 are configured to be released from the restricted state by bending and deforming the pair of side wall portions 124 inward, and the second engaging portion. 127 and the second engaged portion 116 are configured to allow movement in the extending direction of the extending portion 113 of the peripheral wall 121. Along with this movement, the second engagement portion 427 moves from the engagement position (which regulates the movement of the standing wall portion 412 in the standing direction) with respect to the second engaged portion 416, and the engagement relationship is released. . That is, in a state where the covering 120 is assembled to the base 110, the pair of side wall portions 124 remains bent and deformed so that the restriction state of the first engagement portion 126 and the first engaged portion 115 is released. The covering 120 can be detached from the base 110 by sliding the covering 120 in the extending direction of the extending portion 113 (a direction away from the base 111 along the wall surface). Therefore, the protective cover 100 of the present embodiment can construct and maintain a strong fixed relationship between the base 110 and the cover 120 and can easily remove the cover 120 from the base 110. And

The 2nd to-be-engaged part 216 has the latching edge 216a which faces a back side (wall 21 side). The locking edge 216 a is formed by combining an upper straight line portion and a lower inclined portion, and is inclined so that the lower inclined portion is further separated from the wall 11. The portion cut out as the second engaged portion 216 forms an arrangement space 216 b for accommodating the second engaging portion 227. The arrangement space 216b is wider at the lower side. In other words, the locking edge 216a has a recessed portion that is retracted to the side away from the wall 11 on the lower side.

  Then, when removing the cover 220 from the base 210, the cover 220 is bent while the pair of side wall portions 224 are bent inward to release the engagement with the first engaging portion 226 and the first engaged portion 215. When the lower portion of the lower portion is retracted so as to be separated from the wall 11, the second engaging portion 227 enters the concave portion of the locking edge 216a and rotates in the arrangement space 216b as shown in FIG. Move. Specifically, the lower (base 211 side) portion of the second engagement portion 227 tilts in a direction away from the wall 21. Since the space in which the second engaging portion 227 moves freely is secured in the arrangement space 216b, the second engagement portion 227 rotates in the arrangement space 216b without strongly coming into contact with the locking edge 216a. Then, by sliding the covering body 120 upward along the wall surface, the second engaging portion 227 moves along the extending direction of the extending portion 213 and is separated from the arrangement space 216b via the opening portion 216c. To do. As a result, both the first and second engagement relationships are released, and the covering body 220 can be removed from the base 210. That is, in the protective cover 200 of the second embodiment, the second engagement relationship can be released more easily without bending and deforming the extending portion 213.

[Third Embodiment]
FIG. 25 shows the protective cover 300 and the protective structure 30 of the third embodiment. In the protective cover 300 of the third embodiment, the configuration (notch shape) of the second engaged portion 316 is different from the second engaged portion 116, and the other configurations are common. In another embodiment, the constituent elements having the same last two digits in the constituent elements indicated by three digits have the same or similar features unless otherwise specified, and a part of the description is omitted.

  The second engaged portion 316 is formed as a notch having a shape different from that of the second engaged hole 116. The second engaged portion 316 is formed at a position retracted from the front end of the extending portion 313 in the extending direction. The second engaged portion 316 has a locking end edge 316a facing the rear side (wall 31 side). The locking end edge 316a is formed so as to face the engagement surface of the second engagement portion 327 at a portion cut out in a U-shape. The portion cut out as the second engaged portion 316 forms an arrangement space 316 b for accommodating the second engaging portion 327. The arrangement space 316b is wider than that of the first embodiment, and further secures a space in which the second engaging portion 327 can move freely. In the second engagement relationship in which the second engagement portion 327 is disposed in the arrangement space 316b, the engagement surface of the second engagement portion 327 is separated from the locking end edge 316a. When a force is applied in a direction away from 31, the locking edge 316 a acts to lock the second engagement portion 327. And the arrangement | positioning space 316b has the open part 316c narrowed relatively rather than the other site | part.

  When removing the covering 320 from the base 310, the covering 320 is bent while the pair of side wall portions 324 are bent inward to release the engagement with the first engaging portion 326 and the first engaged portion 315. When the lower part of the lower part is retracted so as to be separated from the wall 31, as shown in FIG. 25 (b), the second engaging part 327 rotates in the arrangement space 316b. Since the space where the second engagement portion 327 rotates is secured in the arrangement space 316b, the second engagement portion 327 rotates in the arrangement space 316b without strongly contacting the locking edge 316a. . Specifically, the lower (base 311 side) portion of the second engagement portion 327 tilts in a direction away from the wall 31. Then, the second engagement portion 327 is extended in the extending portion by guiding the second engagement portion 327 to the opening portion 316c while moving freely in the arrangement space 316b, and sliding the covering 320 upward along the wall surface. It moves along the extending direction of 313, and leaves | separates from the arrangement | positioning space 316b through the open part 316c. As a result, both the first and second engagement relationships are released, and the covering 320 can be removed from the base 310. That is, in the protective cover 300 of the second embodiment, the second engagement relationship can be released more easily in conjunction with the release of the first engagement relationship without bending and deforming the extending portion 313. It is.
