Description

[Technical field]

[0001] The present disclosure relates to a storage box installation structure and a storage box installation method. [Background technology]

[0002] Conventionally, there is known an installation structure for installing a storage box such as a mailbox in a block wall (wall material) (see, for example, Patent Document 1). The mailbox is arranged so as to penetrate the block wall in the thickness direction. When installing a mailbox in a block wall, blocks are stacked, the mailbox is placed in the middle, and then the blocks are stacked again so that the mailbox is installed by penetrating the block wall.

[0003] [Patent Document 1] JP 2006-230478 A Summary of the Invention [Problem to be solved by the invention]

[0004] There are several types of blocks that make up a block wall, each with a different thickness. Also, decorative materials (surface materials, finishing materials) may be applied to the surface of the blocks. When installing a mailbox in a block wall, the mailbox is installed so that the width of the mailbox that protrudes from the front of the block wall is a constant width. When installing a mailbox in a block wall, the mailbox's position in the depth direction is adjusted according to the thickness of the block wall, and then the mailbox is placed.

[0005] When the thickness of the blocks or decorative materials differs, the position of the mailbox in the depth direction differs, making it difficult to determine the position of the mailbox in the depth direction. Therefore, when installing a mailbox in a block wall (wall material), it is required to be able to easily determine the position of the mailbox in the depth direction.

[0006] An object of the present disclosure is to provide a storage box installation structure and a storage box installation method that can be easily installed on a wall material. [Means for solving the problem]

[0007] The present disclosure relates to an installation structure for a storage box comprising a box body arranged to penetrate a wall material in the thickness direction, and a plurality of positioning portions provided at intervals in the depth direction on the underside of the bottom of the box body and serving as markers for positioning the box body in the depth direction relative to the wall material.

[0009] The mounting structure of a mailbox 1 (storage box) according to one embodiment will be described. In this embodiment, the depth direction when a person faces the front of the mailbox 1 is referred to as the "depth direction." In the depth direction of the mailbox 1, the near side is referred to as the front side (diagonally left front side in FIG. 1), and the far side (diagonally right rear side in FIG. 1) is referred to as the rear side. In addition, the left-right direction when a person faces the front of the mailbox 1 is referred to as the "left-right direction."

[0010] In an installation structure for a mailbox 1 according to one embodiment, the mailbox 1 is disposed so as to penetrate a block wall 10 (wall material) as shown in Fig. 1. The block wall 10 on which the mailbox 1 is disposed is constructed by stacking a number of concrete blocks 11, and is formed into a wall of a predetermined thickness. A decorative material 12 (surface material, finishing material) is provided on the front and rear surfaces of the block wall 10.

[0011] The decorative material 12 may be, for example, a painted surface of the block 11 or a tile or decorative panel attached to the surface of the block 11. In this embodiment, the decorative material 12 is provided on both the front and rear surfaces of the block wall 10, but is not limited to this and may be provided on only one of the front or rear surfaces of the block wall 10.

[0012] The mailbox 1 of this embodiment is a mailbox that stores delivered items such as mail and newspapers. The mailbox 1 has, for example, a front-loading and rear-removal structure. The mailbox 1 is attached to a block wall 10, which has a decorative material 12 on its surface, by penetrating the wall in the thickness direction. The mailbox 1 may also have a front-loading and front-removal structure. In this embodiment, the mailbox 1 is described as an example of a storage box, but storage boxes include, in addition to the mailbox 1, for example, delivery boxes for storing parcels.

[0013] As shown in Figures 2 to 4, the mailbox 1 comprises a mailbox body 2 (box body) having a front opening 2a (see Figure 4) and a rear opening 2b (see Figure 4), a cap portion 3 attached to the front side of the mailbox body 2, a front door 4 arranged in front of the cap portion 3, and a rear door 5 arranged at the rear side of the mailbox body 2. The front door 4 is attached so as to be able to open and close the front opening 2a of the mailbox body 2. The rear door 5 is attached so as to be able to open and close the rear opening 2b of the mailbox body 2, at the rear side of the mailbox body 2.

[0014] As shown in Figs. 2 to 4, the post body 2 is formed with a box-shaped mail storage chamber 21 and a cylindrical protruding tubular portion 22 that protrudes forward from the top of the mail storage chamber 21. A horizontally long front opening 2a that opens toward the front side is formed in the protruding tubular portion 22. A horizontally long rear opening 2b that opens toward the rear side is formed in the mail storage chamber 21. The mouth portion 3 is formed in a rectangular frame shape and is attached along the periphery of the front opening 2a of the protruding tubular portion 22 of the post body 2.

[0015] 5 and 6, a spacer member 24 is attached to the lower front surface portion 23 of the post body 2, which extends downward from the rear end of the lower surface of the protruding tubular portion 22 below the protruding tubular portion 22. The spacer member 24 is attached to the lower front surface portion 23 of the post body 2 so that if there is a gap between the lower front surface portion 23 of the post body 2 and the decorative material 12 when the mailbox 1 is installed in the block wall 10, the gap between the lower front surface portion 23 of the post body 2 and the decorative material 12 is reduced, as shown in FIG.

[0016] The spacer member 24 is formed of, for example, a resin plate material or a metal plate material. As shown in Fig. 5 and Fig. 6, the spacer member 24 is formed in a plate shape having a thickness in the depth direction. The spacer member 24 has a front plate 241 extending in the up-down and left-right directions, a rearward protruding hook plate 242 extending rearward from an upper end of the front plate 241, a lower plate 243 extending rearward from a lower end of the front plate 241, and a pair of side plates 244 (see Fig. 6) that are disposed on both sides of the left-right ends, have a width in the depth direction, and extend in the up-down direction.

[0017] The front plate 241 is disposed parallel to the lower front portion 23 of the post body 2, at a position spaced forward from the lower front portion 23 of the post body 2. The lower plate 243 extends horizontally rearward from the lower end portion of the front plate 241, and extends to the front end portion of the lower surface of the bottom plate portion 25 of the post body 2.

[0018] The rearward protruding hook plate 242 has an extension plate 242a extending rearward from the upper end of the front plate 241, and an upwardly inclined protruding plate 242b protruding rearward at an upward incline from the rear end of the extension plate 242a.

[0019] In the above-mentioned spacer member 24, the inclined protruding plate 242b of the rear protruding hook plate 242 is hooked onto the upwardly inclined portion 221 which is provided at the rear end of the underside of the protruding tubular portion 22 of the post body 2 near the boundary between the protruding tubular portion 22 and the lower front surface portion 23, and the lower plate 243 is fixed to the underside of the post body 2 by screws 243a.

[0020] 3, a plurality of depth-direction extending fins 251 extending in the depth direction and arranged side by side in the left-right direction, and a plurality of left-right extending fins 252 (positioning portions) extending in the left-right direction and arranged side by side in the depth direction are formed on the underside of the bottom plate portion 25 (bottom portion) of the post body 2. The bottom plate portion 25 of the post body 2 is molded from a resin material.

[0021] The multiple depth-direction extending fins 251 are formed to protrude downward from the lower surface of the bottom plate portion 25 of the post body 2 by a predetermined height, and are formed in a plate shape having a thickness in the left-right direction and extending in the depth direction. The multiple depth-direction extending fins 251 are provided lined up in the left-right direction at predetermined intervals in the left-right direction over the entire left-right area on the lower surface of the bottom plate portion 25 of the post body 2. The multiple depth-direction extending fins 251 are provided to remove weight from the lower surface of the bottom plate portion 25 when the bottom plate portion 25 is molded from resin, for example.

[0022] The left-right extending fins 252 are formed to protrude downward from the lower surface of the bottom plate portion 25 of the post body 2 by a predetermined height, and are formed in a plate shape having a thickness in the depth direction and extending in the left-right direction. The left-right extending fins 252 are provided in a line in the depth direction at a predetermined interval in a part of the depth direction on the lower surface of the bottom plate portion 25 of the post body 2. The left-right extending fins 252 are provided, for example, in a range corresponding to the types of widths of the multiple types of block walls 10 to be used. In this embodiment, as shown in FIG. 3, the left-right extending fins 252 are provided, for example, five at intervals of 10 mm in a predetermined region from the center side to the front side in the depth direction on the lower surface of the bottom plate portion 25 of the post body 2.

[0023] The multiple left-right extending fins 252 serve as marks for positioning the post body 2 in the depth direction relative to the block wall 10 (blocks 11 and decorative material 12) depending on whether the thickness of the blocks 11 or the thickness of the decorative material 12 is different when installing the mailbox 1 on the block wall 10. The multiple left-right extending fins 252 are configured with left-right extending fins 252 that serve as end positioning parts that serve as marks for aligning with the position of the rear end (end on the far side) in the depth direction of the block wall 10. Specific examples of methods for positioning and installing the mailbox 1 on block walls 10 of different thicknesses will be described later.

[0024] As shown in Fig. 3, when the rear door 5 is in the closed position, it is formed in a horizontally long rectangular shape that covers the entire rear part of the post body 2 when the mailbox 1 is viewed from the rear side. As shown in Fig. 4, the rear door 5 is configured to be rotatable about a rotation axis J1 provided at the bottom of the post body 2 to open and close the rear opening 2b of the post body 2.

[0025] 3, 4 and 7, the rear door 5 has a rear door front panel 51 provided with an operation opening 511a, an inner cover material 52, and a latch mechanism 53 provided on the inner side between the rear door front panel 51 and the inner cover material 52. The rear door front panel 51 has a rectangular front panel 511 and a peripheral bent portion 512 (see FIG. 7) that is bent forward at the periphery of the front panel 511.

[0026] The operation opening 511a opens in a rectangular shape extending laterally at the lower side of the rear door front panel 51. As shown in Fig. 7, an operation part 54 of the latch mechanism 53 is disposed on the inner side above the operation opening 511a in the rear door front panel 51. The latch mechanism 53 is disposed at an upper part on the inner side of the upper part of the rear door front panel 51, and is provided in a position that cannot be seen from the front on the rear side of the rear door 5.

[0027] 7, the latch mechanism 53 has an operation section 54 having an engagement claw portion 541 and an operation protrusion 542, and a biasing member 55 that biases the engagement claw portion 541 of the operation section 54 toward the side where the engagement claw portion 541 engages with the engaged metal fitting 26 provided at the upper part of the rear part of the post body 2. When the rear door 5 is in the closed position, the operation protrusion 542 extends downward at the lower part of the operation section 54 and is curved forward at the lower part. The operation protrusion 542 is provided at a position where it can be hooked by hand and moved rearward by inserting a hand into the interior between the rear door front panel 51 and the inner cover material 52 from the operation opening 511a when the rear door 5 is in the closed position.

[0028] When the rear door 5 is in the closed position, the engaging claw portion 541 is provided to engage with the engaged metal fitting 26 provided on the upper part of the rear part of the post body 2 by the biasing force of the biasing member 55. The engaging claw portion 541 is configured to be able to be engaged with and disengaged from the engaged metal fitting 26 by hooking the hand on the operating protrusion 542 and moving it rearward.

[0029] The latch mechanism 53 configured as described above is provided in a position that is not visible from the front on the rear side of the rear door 5 when the rear door 5 is in the closed position. When the rear door 5 is in the closed position, the rear door 5 can be opened by inserting a hand through the operation opening 511a and operating the operation protrusion 542 of the operation part 54 to disengage the engagement claw part 541 from the engaged metal fitting 26 of the post body 2.

[0030] Furthermore, when closing the rear door 5, by closing the rear door 5 from an open state, the engaging claw portion 541 of the latch mechanism 53 climbs over the engaged metal fitting 26 of the post body 2, and the engaging claw portion 541 of the latch mechanism 53 engages with the engaged metal fitting 26 of the post body 2. As a result, the engaging claw portion 541 engages with the engaged metal fitting 26, and the rear door 5 is maintained in the closed position.

[0031] As shown in Figures 4 and 5, the front door 4 is configured to be able to open and close the front opening 2a of the post body 2. The front door 4 is rotatable about a rotation axis J2 provided at the upper part. When the front door 4 is in the closed position as shown in Figure 2, the front door 4 is formed in a horizontally long rectangular shape that covers the entire front side of the cap part 3 provided at the upper part of the front part of the post body 2 when the mailbox 1 is viewed from the front side.

[0032] In this embodiment, the front door 4 is configured to be rotatable around a rotation axis J2 provided on the front side of the upper part of the front door 4, as shown in Figure 5. This reduces the protruding dimension of the front door 4 compared to when the rotation axis is provided, for example, inside the rear side of the post body 2 in the depth direction, making the protruding width of the front door 4 appear smaller.

[0033] The drainage structure of the front portion of the mailbox 1 will be described. As shown in Fig. 8, an upper rear protruding plate 41 that protrudes rearward is provided at the upper part of the back surface of the front door 4, between the front door 4 and the mouth piece 3 attached to the front surface of the mailbox body 2. As shown in Figs. 9 and 10, the mouth piece 3 is formed in a rectangular frame shape that is long in the left-right direction, and has an upper frame part 31, a lower frame part 32, and a pair of vertical frame parts 33 arranged at the left and right ends. An upper cover piece 34 that has a front protruding part 341 and has an inverted L-shaped cross section that extends in the left-right direction is fixed to the front surface of the upper part of the upper frame part 31.

[0034] 8, a front protruding portion 341 of the upper cover piece 34 fixed to the upper part of the upper frame part 31 of the nozzle part 3 is disposed to cover from above the upper surface of the rear side of the upper rear protruding plate 41 of the front door 4. Since the front door 4 rotates with respect to the nozzle part 3, a water intrusion flow path R1 through which water intrudes is formed between the front door 4 and the nozzle part 3, between the upper rear protruding plate 41 of the front door 4 and the front protruding portion 341 of the upper cover piece 34 of the nozzle part 3.

[0035] As shown in FIGS. 8 and 9, the cap portion 3 has an upper gutter portion 36 formed in the lower portion of the upper frame portion 31, and a lower inclined guide portion 37 formed in the lower frame portion 32.

[0036] The upper gutter portion 36 is formed in the upper frame portion 31. The upper gutter portion 36 is disposed below a water intrusion flow path R1 formed between the upper rear protruding plate 41 of the front door 4 and the upper end projection 431 of the upper cover piece 34 of the mouth portion 3. The upper gutter portion 36 has a bottom plate 361, a closing wall 362 formed on the rear side, and a front wall 363 of a predetermined height formed on the front side. As shown in Fig. 9, end side communication paths 364 that communicate downward are formed on the sides of both left and right ends of the upper gutter portion 36.

[0037] 8 to 10, the lower inclined guide portion 37 is formed in the lower frame portion 32. The lower inclined guide portion 37 has a rear upper step portion 371 formed on the rear side and sloping slightly downward toward the front, a front inclined lower step portion 372 formed on the front side and sloping slightly downward toward the front, a downward inclined step portion 373 extending downward toward the front and connecting between the rear upper step portion 371 and the front inclined lower step portion 372, and a lower communication portion 374 formed in front of the front inclined lower step portion 372.

[0038] 8, when water enters between the front door 4 and the nozzle 3 from above through the water intrusion flow path R1 between the upper rear protruding plate 41 of the front door 4 and the front protruding portion 341 of the upper cover piece 34 of the nozzle 3, the water that has entered through the water intrusion flow path R1 between the upper rear protruding plate 41 of the front door 4 and the upper end projection 431 of the upper cover piece 34 of the nozzle 3 flows into the upper gutter 36.

[0039] Water that flows into the upper gutter 36 flows downward through end-side communication passages 364 (see FIG. 9) formed on both left and right ends, and is then drained. When a large amount of water flows into the upper gutter 36 and the water cannot be completely drained downward through the end-side communication passages 364 formed on both left and right ends, the water accumulates in the upper gutter 36 and overflows from the front wall 363, as shown in FIG. 8, and the water that has overflowed the front wall 363 flows downward through the gap between the front surface of the front wall 363 and the front door 4.

[0040] Water that flows downward through the gap between the front surface of the front wall 363 and the front door 4 is channeled into the lower inclined guide section 37 and guided by the rear upper section 371, the downward inclined step section 373 and the front inclined lower section 372 to the lower connecting section 374 formed in front of the lower inclined guide section 37, or is channeled directly into the lower connecting section 374 formed in front of the lower inclined guide section 37 and flowed downward by the lower connecting section 374 to be drained.

[0041] In addition, water may infiltrate the protruding tubular portion 22 of the post body 2 behind the rear upper stage 371 of the lower inclined guide portion 37. In this case, the water that has infiltrated into the bottom of the protruding tubular portion 22 of the post body 2 is guided to the front by the bottom inclined guide portion 222 formed at the bottom of the protruding tubular portion 22 of the post body 2, as shown in Figs. 8 and 10. The bottom inclined guide portion 222 has a rear downward inclined portion 222a formed on the rear side and inclined downward to the front, and a front lower inclined portion 222b formed continuously to the front side of the rear downward inclined portion 222a and inclined slightly downward to the front. The water that has infiltrated into the bottom of the protruding tubular portion 22 of the post body 2 is guided to the front by the bottom inclined guide portion 222, and is drained downward by a plurality of drainage gaps 222c (see Fig. 10) formed on the front side of the bottom inclined guide portion 222 and arranged apart in the left-right direction and communicating downward.

[0042] Next, regarding the procedure for attaching the mailbox 1 to the block wall 10 (construction method for the storage box mounting structure), we will mainly explain the procedure for positioning the mailbox 1 in the depth direction and attaching it to the block wall 10 when the depth width of the block wall 10 (the depth width of the blocks 11 and the thickness of the decorative material 12) is different.

[0043] As shown in Fig. 11, four left-right extending fins 252a, 252b, 252c, 252d are provided on the underside of the bottom plate portion 25 of the post body 2. Here, the number of fins and their positions in the depth direction are different from the configuration in Fig. 3 described in the above embodiment in which five left-right extending fins 252 are provided on the underside of the bottom plate portion 25 of the post body 2. The number and positions in the depth direction of the left-right extending fins are appropriately set depending on the length in the depth direction of the post body 2 and the types of depth direction widths of the multiple types of block walls 10 to be used.

[0044] As shown in Fig. 11, the multiple left-right extending fins 252a, 252b, 252c, 252d are arranged in a line of four in the depth direction. When attaching the mailbox 1 to the block wall 10, the mailbox 1 is attached with the rear end 3a of the cap part 3 attached to the rear part of the front door 4 aligned with the front end of the block wall 10 (see Figs. 12 to 15). This allows the mailbox 1 to be placed on the block wall 10 so that the lower front surface formed below the protruding tubular part 22 of the mailbox body 2 is not visible from the front side.

[0045] In this embodiment, when attaching the mailbox 1 to the block wall 10, if one attempts to place the mailbox 1 on top of the stacked blocks 11, it is difficult to position the rear end 3a of the mouth part 3 at the front end of the block wall 10 because the mouth part 3 is positioned above and away from the blocks 11. Therefore, by positioning the mailbox 1 in the depth direction relative to the rear end 10a of the block wall 10 (see Figures 12 to 15), the rear end 3a of the mouth part 3 is positioned and placed at the front end of the block wall 10.

[0046] In this embodiment, in order to position the mailbox 1 in the depth direction relative to the rear end 10a of the block wall 10, four left-right extending fins 252a, 252b, 252c, and 252d that serve as markers for positioning in the depth direction are provided on the underside of the post body 2. The four left-right extending fins 252a, 252b, 252c, and 252d are provided at positions corresponding to the depth widths of the multiple types of block walls 10 so as to serve as markers corresponding to the thicknesses of the multiple types of block walls 10 in the depth direction.

[0047] 11, on the underside of the bottom plate 25 of the post body 2, the four left-right extending fins 252a, 252b, 252c, 252d are arranged in the following order from front to rear, with the rear end 3a of the cap 3 as a reference position K: the first left-right extending fin 252a, the second left-right extending fin 252b, the third left-right extending fin 252c, and the fourth left-right extending fin 252d. The rear end 3a of the cap 3 is located at a distance Lx (for example, Lx=38.5 mm) from the front surface of the front door 4 to the rear.

[0048] The first left-right extending fin 252a is disposed at a distance L1 (for example, L1 = 160 mm) rearward in the depth direction from a reference position K where the rear end 3a of the base portion 3 is located, and extends in the left-right direction.

[0049] The second left-right extending fin 252b is disposed at a distance L2 (e.g., L2=190 mm) rearward in the depth direction from a reference position K at which the rear end 3a of the base portion 3 is located, and extends in the left-right direction. The second left-right extending fin 252b is disposed at a distance La (e.g., La=30 mm) rearward in the depth direction from the first left-right extending fin 252a.

[0050] The third left-right extending fin 252c is disposed at a distance L3 (e.g., L3 = 200 mm) rearward in the depth direction from a reference position K at which the rear end 3a of the base portion 3 is located, and extends in the left-right direction. The third left-right extending fin 252c is disposed at a distance Lb (e.g., Lb = 10 mm) rearward in the depth direction from the second left-right extending fin 252b.

[0051] The fourth left-right extending fin 252d is disposed at a distance L4 (e.g., L2=230 mm) rearward in the depth direction from a reference position K at which the rear end 3a of the base portion 3 is located, and extends in the left-right direction. The fourth left-right extending fin 252d is disposed at a distance Lc (e.g., Lc=30 mm) rearward in the depth direction from the third left-right extending fin 252c.

[0052] Next, a procedure for attaching a mailbox 1 to a block wall 10 when the width in the depth direction of the blocks 11 and the thickness of the decorative material 12 are different will be specifically described.

[0053] When attaching the post body 2 of the mailbox 1 to the block wall 10, first the lower part of the block wall 10 is installed (wall material arranging process). Then, the post body 2 is arranged on top of the lower part of the block wall 10 (box arrangement process).

[0054] When placing the post body 2 at the top of the lower part of the block wall 10, the post body 2 is positioned in the depth direction relative to the block wall 10 using as a guide a number of left-right extending fins 252a, 252b, 252c, 252d spaced apart in the depth direction on the underside of the bottom plate portion 25 of the post body 2.

[0055] Here, first to fourth installation examples (Figs. 12 to 14) will be described, which are installation examples in which the post body 2 of the mailbox 1 is installed on block walls 10 having different depth widths. In the first to fourth installation examples (Figs. 12 to 14), the depth width of the block 11 and the thickness of the pair of decorative materials 12 provided at both ends of the block 11 in the width direction are different. First, the depth width of the block wall 10 used in the first to fourth installation examples (depth width of the block 11, thickness of the decorative materials 12) will be described.

[0056] 12, the first installation example is an installation example where the width in the depth direction of the block 11 is width W1 (e.g., 150 mm), and the thickness of each of a pair of decorative materials 12 provided at both ends of the width direction of the block 11 is thickness H1 (e.g., 20 mm). In the first installation example, the width WT1 in the depth direction of the block wall 10 is width W1 (150 mm) of the block 11 + thickness H1 (20 mm) of the decorative materials 12 × 2 = 190 mm.

[0057] 13, the second installation example is an installation example in which the width in the depth direction of the block 11 is width W1 (e.g., 150 mm), and the thickness of each of a pair of decorative materials 12 provided at both ends of the width direction of the block 11 is thickness H2 (e.g., 40 mm). In the second installation example, the width WT2 in the depth direction of the block wall 10 is width W1 (150 mm) of the block 11 + thickness H2 (40 mm) of the decorative materials 12 × 2 = 230 mm.

[0058] 14, the third installation example is an installation example in which the width in the depth direction of the block 11 is width W2 (e.g., 120 mm), and the thickness of each of a pair of decorative materials 12 provided at both ends of the width direction of the block 11 is thickness H1 (e.g., 20 mm). In the third installation example, the width WT3 in the depth direction of the block wall 10 is width W2 (120 mm) of the block 11 + thickness H2 (20 mm) of the decorative materials 12 × 2 = 160 mm.

[0059] 15, the fourth installation example is an installation example in which the width in the depth direction of the block 11 is width W2 (e.g., 120 mm), and the thickness of each of a pair of decorative materials 12 provided at both ends of the width direction of the block 11 is thickness H2 (e.g., 40 mm). In the fourth installation example, the width WT4 in the depth direction of the block wall 10 is width W2 (120 mm) of the block 11 + thickness H2 (40 mm) of the decorative materials 12 × 2 = 200 mm.

[0060] When attaching the mailbox 1 to the block wall 10, in the first installation example, as shown in Fig. 12, the blocks 11 used in the first installation example are stacked in a plurality of layers, and the decorative material 12 is attached to the surface of the block 11. In the first installation example, since the width WT1 of the block wall 10 is 190 mm, the second left-right extending fin 252b from the front, which is located at a distance L2 (190 mm) from the reference position K, is aligned with the rear end portion 10a of the block wall 10 (the rear end portion of the decorative material 12). For example, if the width WT1 of the block wall 10 is 190 mm, by stating in the installation manual for the mailbox 1 that the second left-right extending fin 252b is aligned with the rear end portion 10a of the block wall 10 (the rear end portion of the decorative material 12), an operator can easily align the mailbox 1 in the depth direction relative to the block wall 10.

[0061] When aligning the second left-right extending fin 252b, which is the second from the front, with the rear end 10a of the block wall 10 (the rear end of the decorative material 12), the mailbox 1 can be looked at from below and the depth direction position of the second left-right extending fin 252b can be easily aligned with the rear end 10a of the block wall 10. In the first installation example, of the multiple left-right extending fins 252a, 252b, 252c, and 252d, the second left-right extending fin 252b constitutes an end side positioning portion that serves as a mark for aligning with the rear end 10a (the end on the far side) of the block wall 10 in the depth direction. After aligning the depth direction position of the second left-right extending fin 252b, the mailbox 1 is fixed with mortar, and then the remaining blocks 11 are stacked and the decorative material 12 is attached to the surface of the blocks 11.

[0062] Similarly, in the second installation example, as shown in Fig. 13, since the width WT2 of the block wall 10 is 230 mm, the fourth left-right extending fin 252d, which is the fourth from the front side and located at a distance L4 (230 mm) from the reference position K, is aligned with the rear end 10a of the block wall 10 (the rear end of the decorative material 12). For example, if the width WT1 of the block wall 10 is 230 mm, by stating in the installation manual of the mailbox 1 that the fourth left-right extending fin 252d is aligned with the rear end 10a of the block wall 10 (the rear end of the decorative material 12), the worker can easily align the mailbox 1 in the depth direction with respect to the block wall 10. In the second installation example, of the multiple left-right extending fins 252a, 252b, 252c, 252d, the fourth left-right extending fin 252d constitutes an end side positioning portion that serves as a mark for aligning with the rear end 10a of the block wall 10 in the depth direction.

[0063] Similarly, in the third installation example, as shown in Fig. 14, since the width WT2 of the block wall 10 is 160 mm, the first left-right extending fin 252a, which is the first from the front side and located at a distance L1 (160 mm) from the reference position K, is aligned with the rear end 10a of the block wall 10 (the rear end of the decorative material 12). For example, if the width WT1 of the block wall 10 is 160 mm, by stating in the installation manual of the mailbox 1 that the first left-right extending fin 252a is aligned with the rear end 10a of the block wall 10 (the rear end of the decorative material 12), the worker can easily align the mailbox 1 in the depth direction with respect to the block wall 10. In the third installation example, of the multiple left-right extending fins 252a, 252b, 252c, and 252d, the first left-right extending fin 252a constitutes an end-side positioning portion that serves as a mark for aligning with the rear end 10a of the block wall 10 in the depth direction.

[0064] Similarly, in the fourth installation example, as shown in Fig. 15, since the width WT2 of the block wall 10 is 200 mm, the third left-right extending fin 252c, which is the third from the front and located at a distance L3 (200 mm) from the reference position K, is aligned with the rear end 10a of the block wall 10 (the rear end of the decorative material 12). For example, if the width WT1 of the block wall 10 is 200 mm, the installation manual for the mailbox 1 may state that the third left-right extending fin 252c is aligned with the rear end 10a of the block wall 10 (the rear end of the decorative material 12), so that the worker can easily align the mailbox 1 in the depth direction with respect to the block wall 10. In the fourth installation example, of the multiple left-right extending fins 252a, 252b, 252c, and 252d, the third left-right extending fin 252c constitutes an end-side positioning portion that serves as a mark for aligning with the rear end 10a of the block wall 10 in the depth direction.

[0065] As described above, when the depth direction width of the block 11 and the thickness of the decorative material 12 are different, by aligning the position of the left-right extending fin corresponding to the width of the block wall 10 with the position of the rear end portion 10a of the block wall 10, the mailbox 1 can be easily attached to the block wall 10 even when the depth direction width of the block 11 and the thickness of the decorative material 12 are different.

[0066] The mounting structure for the mailbox 1 of this embodiment described above provides the following advantages.

[0067] In this embodiment, the mounting structure of the mailbox 1 comprises a post body 2 disposed so as to penetrate the block wall 10 in the thickness direction, and a plurality of left-right extending fins 252a, 252b, 252c, 252d provided at intervals in the depth direction on the underside of the bottom plate portion 25 of the post body 2 and serving as markers for positioning the post body 2 in the depth direction relative to the block wall 10. As a result, by arranging the plurality of left-right extending fins 252a, 252b, 252c, 252d in accordance with the position of the block wall 10, it is possible to easily position the post body 2 in the depth direction relative to the block wall 10.

[0068] In addition, in this embodiment, the multiple left-right extending fins 252a, 252b, 252c, 252d are formed in a plate shape protruding downward from the lower surface of the bottom plate portion 25 of the post body 2. As a result, the multiple left-right extending fins 252a, 252b, 252c, 252d can be provided in an integrated configuration on the lower surface of the bottom plate portion 25 of the post body 2, so that the multiple left-right extending fins 252a, 252b, 252c, 252d can be provided on the post body 2 with a simple configuration.

[0069] In this embodiment, the multiple left-right extending fins 252a, 252b, 252c, 252d are formed in plate shapes having a thickness in the depth direction and are arranged side by side in the depth direction. As a result, when positioning the post body 2 in the depth direction relative to the block wall 10, it is sufficient to align the plates of the multiple left-right extending fins 252a, 252b, 252c, 252d extending in the left-right direction with the end faces extending in the left-right direction at the rear end portion 10a in the depth direction of the block wall 10, making it easy to position the post body 2 in the depth direction relative to the block wall 10.

[0070] The multiple left-right extending fins 252a, 252b, 252c, 252d have end side positioning portions (left-right extending fins 252a, 252b, 252c, 252d) which serve as landmarks for aligning with the position of the depth-direction rear end portion 10a of the block wall 10. With this, by arranging any one of the multiple left-right extending fins 252a, 252b, 252c, 252d which serve as landmarks for aligning with the position of the depth-direction rear end portion 10a of the block wall 10, in accordance with the position of the rear end portion in the depth direction of the block wall 10, it is possible to easily position the post body 2 in the depth direction relative to the block wall 10. When multiple left-right extending fins 252a, 252b, 252c, 252d are provided on the underside of the bottom plate portion 25 of the post body 2, by, for example, indicating in the installation instructions for the mailbox 1 which of the left-right extending fins 252a, 252b, 252c, 252d corresponds to the width of the block wall 10, a worker can easily align the depth direction of the mailbox 1 with respect to the block wall 10.
