The screws S7 and S6 are then used to connect the two elements, making the height of the lower surface 69 of the lower frame 6B adjustable. The storage box assembly 7 according to this embodiment is formed by stacking multiple mailboxes 7A and multiple delivery boxes 7B in the height direction. Furthermore, the mounting frame of the storage box assembly according to this embodiment is formed by connecting the middle horizontal frame 6 and the lower frame 5 to the left and right outdoor-side vertical frames 2. Therefore, mounting errors may occur in the height of the storage box assembly 7 and the height of the lower space O2. In this embodiment, the height position of the lower surface of the middle horizontal frame 6 (the lower surface 69 of the lower frame 6B) is adjustable, allowing fine adjustment of the height of the lower space O2.

[0039] [F] Frame structure [F-1] Four-round frame The left and right vertical frame assemblies (outdoor-side vertical frame 2 and indoor-side vertical frame 3), the upper frame 4, and the lower frame 5 form a four-sided frame, and the upper and lower four-sided frames are further formed by the intermediate horizontal frame 6. The outdoor-side facing surface 20 of the outdoor-side vertical frame 2, the outdoor-side facing surface 40 of the upper frame 4, and the outdoor-side facing surface 60 of the intermediate horizontal frame 6 are located on approximately the same vertical plane (in this embodiment, the outdoor-side facing surface 20 protrudes slightly outdoors), and the outdoor-side facing surface 50 of the lower frame 5 is located indoors relative to the vertical plane. The indoor-side facing surface 30 of the indoor-side vertical frame 3 and the indoor-side facing surface 41 of the upper frame 4 are located on approximately the same vertical plane (in this embodiment, the indoor-side facing surface 30 protrudes slightly indoors), and the indoor-side facing surface 61 of the intermediate horizontal frame 6 and the indoor-side facing surface 51 of the lower frame 5 are located outdoor relative to the vertical plane.

[0040] As shown in Figure 10, in this embodiment, the outdoor-side four-perimeter frame is formed by left and right outdoor-side vertical frames 2, an outdoor-side upper frame 4A, and a lower frame 5. Intermediate horizontal frames 6 are provided at a predetermined height position of the left and right outdoor-side vertical frames 2. Both longitudinal ends of the outdoor-side upper frame 4A, lower frame 5, and intermediate horizontal frame 6 are welded to the left and right outdoor-side vertical frames 2, but some or all of them may be connected with screws. The outdoor-side four-perimeter frame is configured such that the outer facing edges 27 of the left and right outdoor-side vertical frames 2 are connected to the outdoor facing surface 11 of the core material 1 with screws S1, and the outdoor-side rising edge 47 of the outdoor-side upper frame 4A is connected to the outdoor facing surface 11 of the upper core material 1 with screws S8 (see Figure 7), and the lower ends of the left and right outdoor-side vertical frames 2 and lower frame 5 are embedded in the ground GR and floor FL.

[0041] As shown in Figure 11, the left and right indoor side vertical frames 3, the indoor side upper frames 4B, and the lower end horizontal members 5' form an indoor side four-perimeter frame. Both longitudinal ends of the indoor side upper frames 4B and the lower end horizontal members 5' are connected to the left and right indoor side vertical frames 3 with screws. The indoor side four-perimeter frame is formed such that the projected edges 33 of the left and right indoor side vertical frames 3 are connected to the projected surface 10 of the core member 1 with screws S2, the indoor side rising edges 48 of the indoor side upper frames 4B are connected to the indoor side visible surface 12 of the upper core member 1 with screws S9, and the horizontal edges 461 are connected to the underside 10" of the upper core member 1 with screws S10 (see Figure 7). The lower ends of the left and right indoor side vertical frames 3 and the lower end horizontal members 5' are buried in the ground GR and floor FL.

[0042] The outdoor-side perimeter frame and the indoor-side perimeter frame are connected by screws S3 at the projected edges 25 of the left and right outdoor-side vertical frames 2 and the inside projected faces 31 of the left and right indoor-side vertical frames 3, and the indoor-side horizontal edge 451 of the outdoor-side upper frame 4A abuts against the indoor-side lower face 46 of the indoor-side upper frame 4B and is connected by screws S11 (see Figure 7). The outdoor-side perimeter frame and the indoor-side perimeter frame are connected to form a vertical rectangular perimeter frame, and the opening formed by this perimeter frame is divided into an upper space O1 and a lower space O2 by the intermediate horizontal frame 6 attached to the outdoor-side perimeter frame (see Figure 10). The upper space O1 is an upper opening formed by a four-sided frame consisting of the upper portions of the left and right vertical frame assemblies, the upper frame 4, and the middle horizontal frame 6, and the lower space O2 is a lower opening formed by a four-sided frame consisting of the lower portions of the left and right vertical frame assemblies, the middle horizontal frame 6, and the lower frame 5.

[0043] The window section 8 is formed so as to close the upper space O1. Specifically, left and right vertical window frames 81 are provided on the inside visible surfaces 21 of the left and right outdoor vertical frames 2, positioned in the upper space O1, and both widthwise ends of a panel 80 of the window section 8 are supported in recessed grooves in the vertical window frames 81, with its upper end supported by an upper ledge 82 on the upper frame 4 and its lower end supported by a lower ledge 83 on the intermediate horizontal frame 6.

[0044] [F-2] Side vertical frame As shown in Fig. 1, the side vertical frame 9 is a long frame body extending in the height direction. The side vertical frame 9 has the same height dimension as the outdoor-side vertical frame 2, with its upper end reaching the ceiling CL and its lower end reaching the ground GR, and is installed alongside the outdoor-side vertical frame 2. As shown in Fig. 5, the side vertical frame 9 is made up of an outdoor-side visible surface 90, an inner prospective edge 91 extending in the prospective direction from the inner end of the outdoor-side visible surface 90 towards the indoor side, an outer prospective edge 92 extending in the prospective direction from the outer end of the outdoor-side visible surface 90 towards the indoor side, and an outer prospective edge 93 extending in the prospective direction from the indoor-side end of the outer prospective edge 92 towards the outside.

[0045] The side vertical frame 9 is connected with screws S5 with its outer visible edge 93 abutting against the outdoor-side visible surface 11 of the core material 1, the visible dimension of the inner visible edge 91 being smaller than the visible dimension of the outer visible edge 92, and the tip of the inner visible edge 91 closely facing the outer visible edge 27 of the outdoor-side vertical frame 2. The screws S1 connecting the outer visible edge 27 of the outdoor-side vertical frame 2 to the outdoor-side visible surface 11 of the core material 1 are concealed by the side vertical frame 9, and the screws S5 connecting the side vertical frame 9 to the outdoor-side visible surface 11 of the core material 1 are concealed by the outdoor-side wall material 13. In this embodiment, the side vertical frame 9 covers the space formed by the outdoor-side end visible surface 110 of the wall core material 1 and the visible surface 132 of the outdoor-side wall material 13, but the outdoor-side vertical frame 2 and side vertical frame 9 may also be formed from an integral frame member. In this embodiment, the outdoor vertical frame 2 and the side vertical frame 9 are separate components, and by sandwiching the watertight material WT4 and narrowing the visible width of the outdoor visible surfaces 20, 90, the appearance from the outdoor side is streamlined.In addition, even if the visible dimensions of the space formed inside the visible surface 132 of the outdoor wall material 13 are different, this can be accommodated by changing the visible dimensions of the side vertical frame 9.

[0046] [G] Storage box assembly mounting structure A storage box assembly 7, which is an assembly of multiple mailboxes 7A and multiple delivery boxes 7B, is provided in a lower space O2 (FIG. 10) formed by a four-sided frame consisting of the lower parts of the left and right vertical frame assemblies (outdoor vertical frame 2, indoor vertical frame 3), the middle horizontal frame 6, and the bottom frame 5. Sides 70 of the storage box assembly 7 (one side of the mailbox 7A and one side of the delivery box 7B) abut against the inside visible surface 21 of the outdoor vertical frame 2 at multiple points spaced apart in the height direction and are connected with screws S4.

[0047] 3 and 5, the front surface 70' of the main body 7' of the storage box assembly 7 is substantially flush with the outdoor-side facing surfaces 20 of the left and right outdoor-side vertical frames 2 and the outer facing surfaces 130 of the outdoor-side wall material 13. The outdoor-side facing surface 74 of the storage box assembly 7 (formed by the outdoor-side lid bodies 73A, 73B) is located closer to the outdoors than the outdoor-side facing surfaces 20 of the left and right outdoor-side vertical frames 2 and the outer facing surfaces 130 of the outdoor-side wall material 13. The outdoor-side facing surfaces 90 of the side vertical frames 9 are substantially flush with the outdoor-side facing surface 74 of the storage box assembly 7.

[0048] The outdoor portion 700 of the side surface 70 of the storage box assembly 7 faces the projected edge 23 of the outdoor-side vertical frame 2 at a distance. A vertical groove (vertical groove) extending vertically and concave in cross section is formed between the outdoor portion 700 and a step (projected edge 23, projected edge 22) formed at the outdoor end of the inner projected surface 21 of the outdoor-side vertical frame 2. A watertight material WT1 is provided in the groove along its height (FIGS. 1, 3, and 5). In this embodiment, the outdoor-side projected surface 20 of the outdoor-side vertical frame 2 and the outdoor-side front surface 70' are substantially flush with each other, providing work space to the sides of the outdoor-side lids 73A and 73B, allowing for smooth filling of the watertight material WT1 while avoiding the outdoor-side lids 73A and 73B. From the perspective of ensuring the work space, the outdoor-side projected surface 20 of the outdoor-side vertical frame 2 may be located closer to the interior than the outdoor-side front surface 70'.

[0049] The outdoor portion of the upper surface 71 of the storage box assembly 7 abuts or is close to the lower surface of the intermediate horizontal frame 6 (lower surface 69 of the lower frame 6B), and at the outdoor end of the upper surface 71 of the storage box assembly 7, a groove portion (upper groove portion) that extends horizontally and is concave in side view from the upper surface 71 and the step portion of the outdoor portion of the lower surface of the intermediate horizontal frame 6 (overlapping portion of the lower horizontal edge 65, lower hanging edge 66 and outdoor vertical edge 690), and a watertight material WT2 is provided in the groove portion across the width (Figures 1 and 2).

[0050] The outdoor portion of the underside 72 of the storage box assembly 7 abuts or is in contact with the upper surface 52 of the lower frame 5, and at the outdoor end of the lower surface 72 of the storage box assembly 7, a groove portion (lower groove portion) extending horizontally and concave in side view is formed from the underside 72 and a step portion (vertical edge 53, horizontal edge 54) formed on the outdoor portion of the upper surface of the upper surface 52 of the lower frame 5, and a watertight material WT3 is provided in the groove portion across the width (Figures 1 and 2).

[0051] [H] Watertight structure As shown in FIG. 1 , the outdoor portion of the storage box assembly 7 has a watertight structure formed by left and right watertight materials WT1, an upper watertight material WT2, and a lower watertight material WT3. Grooves are formed around the periphery between the outdoor portion of the storage box assembly 7 and the mounting frame. More specifically, left and right vertical grooves are formed extending in the height direction from the outdoor portion of the side surface 70 of the storage box assembly 7 and the step portion (the visible edge 22, the visible edge 23) of the outdoor portion of the inner visible surface 21 of the outdoor vertical frame 2, and the vertical grooves are filled with the watertight material WT1. An upper groove is formed extending horizontally from the outdoor portion of the top surface 71 of the storage box assembly 7 and the step portion (the overlap portion of the lower horizontal edge 65, the lower hanging edge 66, and the outdoor vertical edge 690) of the outdoor portion of the lower surface (lower surface 69) of the intermediate horizontal frame 6, and the upper groove is filled with the watertight material WT2. Adjusting the height of the lower surface (lower surface 69) of the intermediate horizontal frame 6 does not affect the formation of the upper gutter, and it is possible to fill it with watertight material WT2. A lower gutter is formed extending horizontally from the outdoor portion of the lower surface 72 of the storage box assembly 7 and the step portion (vertical side 53, horizontal side 54) of the outdoor portion of the upper surface 52 of the lower frame 5, and the lower gutter is filled with watertight material WT3.

[0052] Watertight members WT4 and WT5 are provided on both sides of the side vertical frame 9 and extend in the height direction. When the outer visible edge 93 of the side vertical frame 9 is connected to the outdoor-side visible surface 11 of the core material 1 with screws S5, the inner visible edge 91 and the outer visible edge 26 of the outdoor-side vertical frame 2 face each other at a distance, and a groove (first side groove) extending in the height direction is formed. The watertight member WT4 is provided in the groove along the height direction. In the illustrated embodiment, the outer visible edge 26 of the outdoor-side vertical frame 2 and the visible surface 10 of the core material 1 are substantially flush with each other. The outer visible edge 92 of the side vertical frame 9 and the visible surface 132 of the wall material 13 face each other at a distance, and a groove (second side groove) extending in the height direction is formed. The watertight member WT5 is provided in the groove along the height direction ( FIGS. 1 , 3 , and 5 ). The outer prospective edge 92 of the side vertical frame 9 and the outer prospective edge 34 of the indoor side vertical frame 3 are at the same position in the prospective direction.

[0053] A horizontally extending groove (upper end groove) is formed between the outdoor-side upper surface 42 of the top frame 4 and the ceiling CL, and a horizontally extending watertight material WT6 is provided in this groove. The outer projected edge 34 of the indoor-side vertical frame 3 and the projected surface 132 of the wall material 13 are spaced apart and face each other, and a vertically extending groove is formed, and a watertight material WT7 is provided in this groove along the entire height direction (FIGS. 3 and 5). A horizontally extending groove is formed between the indoor-side upper surface 43 of the top frame 4 and the underside 132' of the upper indoor-side wall material 13, and a horizontally extending watertight material WT8 is provided in this groove (FIG. 7 is referenced).
