[Modes for carrying out the invention]

[0013] The embodiments will be described below with reference to the drawings. In the following description, elements having the same function and configuration will be denoted by the same reference numerals.

[0014] [1] Enclosure box Figure 1 shows a perspective view of a storage box enclosure according to one embodiment of the present invention. Figures 2(a) and (b) show a front view and a left side view of the storage box enclosure according to one embodiment of the present invention. Figure 3 shows an exploded view of the storage box enclosure according to one embodiment of the present invention. Figure 4 shows an exploded view of the storage box enclosure in the open state according to one embodiment of the present invention. Note that the heat shield in Figure 1 has been disassembled for convenience to make the structure of the lid and frame easier to see. The structure of the storage box enclosure according to this embodiment will be described below.

[0015] As shown in Figures 1, 2(a) and (b), 3 and 4, the housing box enclosure 100 of this embodiment is composed of a housing-type frame F, a lid 10, a bottom 20, a front door 30, a rear 40, a right side 50, a left side door 60, an opening and closing mechanism 70, and a heat shield 90.

[0016] The lid portion 10 is provided on the upper surface of the frame F. The bottom portion 20 is provided on the bottom surface of the frame F. The front door portion 30 is provided on the front surface of the frame F. The rear portion 40 is provided on the rear surface of the frame F. The right side portion 50 is provided on the right side surface of the frame F. The left side door portion 60 is provided on the left side surface of the frame F.

[0017] The right side section 50 and the left side door section 60 are arranged opposite each other in the X direction, the front door section 30 and the rear section 40 are arranged opposite each other in the Y direction, and the lid section 10 and the bottom section 20 are arranged opposite each other in the Z direction. The right side section 50 is located on one end of the front door section 30, and the left side door section 60 is located on the other end of the front door section 30.

[0018] The opening and closing mechanism 70 connects the front door section 30 to the right side section 50 so as to be openable and closable, and connects the left side door section 60 to the rear section 40 so as to be openable and closable. The opening and closing mechanism 70 includes a first hinge 71, a second hinge 72, a bolt 73, a first nut 74, a second nut 75, and a third nut 76.

[0019] The heat shield 90 is provided on the lid 10. This heat shield 90 protects the equipment inside the housing 100 from heat.

[0020] The frame F, lid 10, bottom 20, front door 30, rear 40, right side 50, left side door 60, opening / closing mechanism 70, and heat shield 90 may be made of metal (e.g., iron), plastic (e.g., polycarbonate), etc., or they may be made of hot-dip galvanized steel (so-called dip galvanizing) which is formed by dipping steel material in molten zinc to form a zinc coating on the surface, or treated with rust prevention treatment such as ZAM® steel plate.

[0021] The installation method of the housing box enclosure 100 according to this embodiment can accommodate various applications, such as pole-mounted type, freestanding type, and wall-mounted type.

[0022] In the storage box housing 100 having the lid portion 10 according to this embodiment, the front door portion 30 and the left side door portion 60 are attached to the right side portion 50 and the rear portion 40, respectively, by an opening and closing mechanism 70, and the front door portion 30 and the left side door portion 60 have a door structure that can be opened and closed. When the front door portion 30 and the left side door portion 60 are opened, the screwed state of the third nut 76 that is screwed onto the bolt 73 is released, which lowers the front door portion 30 and the left side door portion 60, making it possible to open the front door portion 30 and the left side door portion 60 without them coming into contact with the side edge portion 12 of the lid portion 10.

[0023] Furthermore, in the housing casing 100 according to this embodiment, a filler material (for example, waterproof rubber tape, caulking, etc.) can be provided in the gaps between each component to fill these gaps. This further prevents rainwater and the like from entering the housing casing 100.

[0024] [2] Lid part Figures 5(a) to 5(e) show a perspective view, an outer plan view, an inner plan view, a front view, and a right side view of the lid of a storage box housing according to one embodiment of the present invention. Here, Figure 5(d) is a side view from the direction D-D' of Figure 5(c), and Figure 5(e) is a side view from the direction E-E' of Figure 5(c). The structure of the lid of the storage box housing according to this embodiment will be described below.

[0025] As shown in Figures 5(a) to (e), the lid portion 10 has a top plate portion 11, side edge portions 12, and L-shaped mounting brackets 13 and 14. The lid portion 10 is provided to cover the upper parts of the front door portion 30, the rear portion 40, the right side portion 50, and the left side door portion 60.

[0026] The top plate portion 11 has a length P such that its periphery extends outward beyond the outer peripheral edge FE of the upper surface of the frame F. In other words, the upper surface of the top plate portion 11 is larger than the upper surface of the frame F. This enhances the effect of preventing rainwater from entering the housing 100.

[0027] The side edge portion 12 protrudes from the periphery of the top plate portion 11 in the Z direction toward the bottom surface portion 20 (a direction perpendicular to the surface of the top plate portion 11), and extends in a direction parallel to the surfaces of the front door portion 30, the rear portion 40, the right side portion 50, and the left side door portion 60 (the Z direction). The side edge portion 12 has a length L in the Z direction. By increasing the length L of the side edge portion 12 in this way, the effect of preventing rainwater intrusion can be further enhanced.

[0028] The mounting brackets 13 are attached to the inner surface of the top plate portion 11 so as to protrude in the Z direction toward the bottom surface portion 20. The number and position of the mounting brackets 13 can be changed as appropriate, but in this embodiment, for example, one mounting bracket 13 is provided on each of the four sides of the top plate portion 11 (a total of four). These mounting brackets 13 are attached to the mounting brackets F10 of the frame F with bolts and nuts (see Figure 17).

[0029] The mounting brackets 14 are attached to the outer surface of the top plate portion 11 so as to protrude outward in the Z direction. The number and position of the mounting brackets 14 can be changed as appropriate, but in this embodiment, for example, one mounting bracket 14 is provided on each of the four sides of the top plate portion 11 (a total of four). These mounting brackets 14 are attached to the mounting brackets 91 of the heat shield plate 90 with bolts and nuts (see Figure 17).

[0030] [3] Opening and closing mechanism Figures 6(a) and 6(b) show perspective views of the opening and closing mechanism of a storage box housing according to one embodiment of the present invention in the open and closed state. Here, Figure 6(a) shows the opening and closing mechanism with the front door closed, and Figure 6(b) shows the opening and closing mechanism with the front door open. The structure of the opening and closing mechanism of the storage box housing according to this embodiment will be described below.

[0031] As shown in Figure 6(a), the opening and closing mechanism 70 includes a first hinge 71, a second hinge 72, a bolt 73, a first nut 74, a second nut 75, and a third nut 76.

[0032] The first hinge 71 has a first plate-shaped portion 71a and a first cylindrical portion 71b. The first plate-shaped portion 71a is attached to the door portion (in this embodiment, the front door portion 30 and the left side door portion 60) by, for example, welding. The first cylindrical portion 71b is provided on the first plate-shaped portion 71a and has a cylindrical shape into which a bolt 73 can be inserted.

[0033] The second hinge 72 has a second plate-shaped portion 72a and a second cylindrical portion 72b. The second plate-shaped portion 72a is attached, for example, by welding to the side adjacent to the door portion (in this embodiment, the right side portion 50 and the back portion 40). The second cylindrical portion 72b is provided on the second plate-shaped portion 72a and has a cylindrical shape into which a bolt 73 can be inserted.

[0034] The bolt 73 is a long rod-shaped bolt with a length slightly longer than the Z-direction length of the door section (in this embodiment, the front door section 30 and the left side door section 60). The bolt 73 is a so-called threaded rod, a long screw (full thread, long screw) without a head, with a male threaded portion formed on the outer circumference of the rod. The bolt 73 serves as the axis of rotation for the first hinge 71 and the second hinge 72 when the door is opened and closed. The bolt 73 is slidable within the second cylindrical section 72b when the door is opened and closed.

[0035] The first nut 74 is screwed onto one end of the bolt 73 (the end on the lid portion 10 side). The second nut 75 is welded to the other end of the bolt 73 (the end on the bottom portion 20 side), for example. The first nut 74 and the second nut 75 have a cylindrical body. The inner circumferential surface of this body has a female thread that can be screwed onto the male thread of the bolt 73. However, if the second nut 75 is welded to the bolt 73, the inner circumferential surface of the body of the second nut 75 does not need to have a female thread.

[0036] The third nut 76 has a third plate-like portion 76a and a third cylindrical portion 76b. The third plate-like portion 76a is attached, for example, by welding to a side adjacent to the door portion (in this embodiment, the right side portion 50 and the back portion 40). The third cylindrical portion 76b is provided on the third plate-like portion 76a and has a cylindrical shape into which a bolt 73 can be inserted. A female threaded portion is formed on the inner circumferential surface of the third cylindrical portion 76b, which can be screwed onto the male threaded portion of the bolt 73. The length of the third cylindrical portion 76b is longer than the lengths of the first nut 74 and the second nut 75, and is, for example, about the same as the length of the first cylindrical portion 71b and the second cylindrical portion 72b.

[0037] The components attached to the bolt 73 of the opening and closing mechanism 70 of this embodiment are arranged in the following order from the top of the door: first nut 74, third nut 76, first hinge 71, second hinge 72, second hinge 72, first hinge 71, and second nut 75. Therefore, at the top of the door, the first hinge 71 attached to the front door section 30 is located above the second hinge 72 attached to the right side section 50, while at the bottom of the door, the first hinge 71 attached to the front door section 30 is located below the second hinge 72 attached to the right side section 50.

[0038] In the opening and closing mechanism 70 of this embodiment, when the door is closed, as shown in Figure 6(a), at the top of the door, the end of the first cylindrical portion 71b on the second hinge 72 side and the end of the second cylindrical portion 72b on the first hinge 71 side are spaced apart, and the bolt 73 is exposed from this point. This spacing distance D is greater than or equal to the length L of the side edge portion 12 of the lid portion 10. At the bottom of the door, the end of the first cylindrical portion 71b on the second hinge 72 side is in contact with the end of the second cylindrical portion 72b on the first hinge 71 side.

[0039] On the other hand, to open the door, the second nut 75 welded to the bolt 73 is loosened. This also loosens the third nut 76 that is screwed onto the bolt 73, and as the bolt 73 rotates, the first nut 74 moves closer to the third nut 76. Consequently, as shown in Figure 6(b), the first cylindrical portion 71b of the first hinge 71 slides downward, and the door moves down.

[0040] At this point, at the top of the door, the end of the first cylindrical portion 71b on the second hinge 72 side is in contact with the end of the second cylindrical portion 72b on the first hinge 71 side. In contrast, the end of the first cylindrical portion 71b on the third nut 76 side and the end of the third cylindrical portion 76b on the first hinge 71 side are separated by a distance D'. At the bottom of the door, the end of the first cylindrical portion 71b on the second hinge 72 side and the end of the second cylindrical portion 72b on the first hinge 71 side are separated by a distance D'.

[0041] Here, the separation distance D' when the door can be opened is, for example, the same as the separation distance D when the door is closed, and is greater than or equal to the length L of the side edge 12 of the lid 10.

[0042] In the opening and closing mechanism 70 of this embodiment, when opening and closing the door, turning the second nut 75 causes the third nut 76 to move the door up and down. Also, when opening and closing the door, the first hinge 71, the second hinge 72, the second nut 75, and the third nut 76 support the door and contribute to preventing the door from falling.

[0043] In this embodiment, the first plate-like portion 71a is welded to the front door portion 30 and the left side door portion 60, and the second plate-like portion 72a and the third plate-like portion 76a are welded to the right side portion 50 and the rear portion 40. However, the invention is not limited to this, and it is also possible to make the attachments removable using bolts and nuts, etc.

[0044] Furthermore, in this embodiment, one hinge set of the first hinge 71 and the second hinge 72 is provided at the top and bottom of the door, but this is not limited to this, and the number and position can be changed as appropriate.

[0045] Furthermore, the position of the third nut 76 in this embodiment is between the first nut 74 and the first hinge 71 at the top of the door. The third nut 76 also has the function of supporting the door when it is opened and closed, so it is desirable to place it at the top of the door, but it is not limited to this and can be changed in various ways. The number of third nuts 76 is also not limited to one, and it is possible to provide two or more depending on the size of the door, etc.

Note that in Figure 10(b), the second cylindrical portion 72b and the third cylindrical portion 76b shown at the left end of the rear portion 40 are provided on the right side portion 50 and are not attached to the rear portion 40.

[0060] Multiple holes 43 (10 in this embodiment) are provided around the rear portion 40. However, the number and arrangement of the holes 43 are not limited to this figure and can be changed in various ways. Bolts (not shown) are inserted into each of these holes 43, and the rear portion 40 is detachably attached to the frame F.

[0061] [8] Bottom part Figures 11(a) and (b) show a perspective view and a plan view of the bottom surface of a storage box enclosure according to one embodiment of the present invention. The structure of the bottom surface of the storage box enclosure according to this embodiment will be described below.

[0062] As shown in Figures 11(a) and (b), the bottom portion 20 is composed of two bottom portions 20a and 20b. The bottom portions 20a and 20b are separated and formed separately in the direction (X direction) where the right side portion 50 and the left side door portion 60 face each other. Bottom portion 20a is located on the right side portion 50 side, and bottom portion 20b is located on the left side door portion 60 side.

[0063] Multiple holes 21 (six in this embodiment) are provided around the bottom portions 20a and 20b. However, the number and arrangement of the holes 21 are not limited to this figure and can be changed in various ways. Bolts (not shown) are inserted into each of these holes 21, and the bottom portions 20a and 20b are detachably attached to the frame F.

[0064] In this embodiment, the bottom portion 20 of the storage box housing 100 was divided into two parts in the X direction, but this is not the only way to do so. For example, the bottom portions 20a and 20b may be divided in the direction (Y direction) where the front door portion 30 and the rear portion 40 face each other. Also, the bottom portion 20 can be formed as a single piece without being divided into two bottom portions 20a and 20b.

[0065] [9] Heat shield Figures 12(a) to 12(e) show a perspective view, an outer plan view, an inner plan view, a front view, and a right side view of a heat shield plate for a housing casing according to one embodiment of the present invention. Herein, Figure 12(d) is a side view from the direction D-D' of Figure 12(c), and Figure 12(e) is a side view from the direction E-E' of Figure 12(c). The structure of the heat shield plate for the housing casing according to this embodiment will be described below.

[0066] As shown in Figures 12(a) to (e), the heat shield 90 is provided on the lid 10 and is formed to be approximately the same size as the lid 10. The back surface of the heat shield 90 has an L-shaped mounting bracket 91.

[0067] The mounting brackets 91 are attached to the inner surface of the heat shield 90 so as to protrude in the Z direction toward the lid 10. The number and position of the mounting brackets 91 can be changed as appropriate, but in this embodiment, for example, one mounting bracket 91 is provided on each of the four sides of the heat shield 90 (a total of four). These mounting brackets 91 are attached to the mounting brackets 14 of the lid 10 with bolts and nuts (see Figure 17).

[0068] In this embodiment, the heat shield 90 is provided to protect the equipment inside the housing 100 from heat, but it is not necessarily required.

[0069]

[10] Frame Figures 13(a) to 13(f) show a perspective view, left side view, front view, right side view, top view, and bottom view of the frame of a housing enclosure according to one embodiment of the present invention. Figures 14(a) to 14(h), 15(a) to 15(h), and 16(a) to 16(h) show a side view and a plan view of the frame components of a housing enclosure according to one embodiment of the present invention. Figure 17 shows an exploded view and a schematic diagram of the mounting structure of the frame, lid, and heat shield of a housing enclosure according to one embodiment of the present invention. The structure of the frame of the housing enclosure according to this embodiment will be described below.

[0070] As shown in Figures 13(a) to (f), 14(a) to (h), 15(a) to (h), and 16(a) to (h), the housing-type frame F of this embodiment is composed of frame components F1 to F12.

[0071] The frame components F1 to F12 in this embodiment are L-shaped, but are not limited to this and can be modified in various ways.

[0072] As shown in Figure 17, in the mounting structure of the frame F, lid 10, and heat shield 90 of this embodiment, the mounting bracket F10 of the frame F is attached to the mounting bracket 13 of the lid 10 with bolts and nuts, and the mounting bracket 14 of the lid 10 is attached to the mounting bracket 91 of the heat shield 90 with bolts and nuts. However, the mounting structure with bolts and nuts can be modified in various ways.

[0073] Here, the frame F and the lid 10 are attached without gaps using mounting brackets F10 and F13. On the other hand, the lid 10 and the heat shield 90 are attached with a gap using mounting brackets 14 and F11. This prevents heat from directly hitting the housing 100 and creates a structure that prevents heat from accumulating inside.

[11] Opening and closing method Figures 18(a) to 18(d) show perspective views of the storage box housing according to one embodiment of the present invention when the door is opened. Figures 19(a) to 19(d) show perspective views of the storage box housing according to one embodiment of the present invention when the door is closed. The method for opening and closing the door of the storage box housing according to this embodiment will be described below. In this description, the front door 30 will be used as an example.

[0075] As shown in Figure 18(a), the components attached to the bolt 73 of the opening / closing mechanism 70 of this embodiment are arranged from the top of the door in the following order: first nut 74, third nut 76, first hinge 71, second hinge 72, second hinge 72, first hinge 71, and second nut 75.

[0076] In this embodiment, when the front door 30 of the storage box housing 100 is closed, as shown in Figure 18(a), at the top of the door, the end of the first cylindrical portion 71b on the second hinge 72 side and the end of the second cylindrical portion 72b on the first hinge 71 side are spaced apart, and this spacing D is greater than or equal to the length L of the side edge 12 of the lid portion 10. Also, the first nut 74 is spaced apart from the end of the third cylindrical portion 76b on the first nut 74 side, and it is desirable that this spacing is also greater than or equal to the length L of the side edge 12 of the lid portion 10. On the other hand, at the bottom of the door, the end of the first cylindrical portion 71b on the second hinge 72 side is in contact with the end of the second cylindrical portion 72b on the first hinge 71 side.

[0077] To open the front door section 30, first remove the bolts and nuts from the holes 33 in the front door section 30, as shown in Figure 18(b).

[0078] Next, as shown in Figure 18(c), the second nut 75 welded to the bolt 73 is rotated to loosen it. This also loosens the third nut 76 that is screwed onto the bolt 73, releasing the screw connection between the bolt 73 and the third cylindrical part 76b, and the first nut 74 moves closer to the third nut 76. Consequently, the first cylindrical part 71b of the first hinge 71 slides downward, causing the door to move down.

[0079] Then, as shown in Figure 18(d), when the top of the front door section 30 has lowered to the point where it no longer touches the side edge 12 of the lid section 10, the front door section 30 is opened forward.

[0080] In this state, with the front door 30 open, at the top of the door, the end of the first cylindrical portion 71b on the second hinge 72 side is in contact with the end of the second cylindrical portion 72b on the first hinge 71 side. In contrast, the end of the first cylindrical portion 71b on the third nut 76 side and the end of the third cylindrical portion 76b on the first hinge 71 side are separated by a distance D'. At the bottom of the door, the end of the first cylindrical portion 71b on the second hinge 72 and the end of the second cylindrical portion 72b on the first hinge 71 side are separated by a distance D'.

[0081] Next, when closing the open front door 30 as shown in Figure 19(a), first, as shown in Figure 19(b), the front door 30 is closed so that it is inside the side edge 12 of the lid 10.

[0082] Next, as shown in Figure 19(c), the second nut 75 welded to the bolt 73 is rotated and tightened. This tightens the third cylindrical portion 76b, which is screwable with the bolt 73, causing the bolt 73 and the third cylindrical portion 76b to screw together, and the first nut 74 to move away from the third nut 76. As a result, the first cylindrical portion 71b of the first hinge 71 slides upward, and the door rises.

[0083] Then, as shown in Figure 19(d), once the top of the front door section 30 is raised to its highest point, a bolt is inserted into the hole 33 of the front door section 30 and tightened.

[0084] As described above, in this embodiment, when opening the front door portion 30 of the storage box housing 100 having the lid portion 10, the screwed state of the bolt 73 and the third nut 76 is released, allowing the front door portion 30 to be lowered by a separation distance D (D≧L). Therefore, the front door portion 30 can be opened without the front door portion 30 hitting the side edge portion 12 of the lid portion 10.

[0085]

[12] Variant Figure 20 shows a perspective view of a modified example of the housing enclosure according to one embodiment of the present invention. The structure of the modified example of the housing enclosure according to the present invention will be described below.

[0086] As shown in Figure 20, in this modified version of the storage box housing 100 of this embodiment, the difference from the structure in Figure 1 is that, at the top of the door, the second hinge 72 is provided above the first hinge 71 on the lid 10 side. In other words, in the opening and closing mechanism 70 of the modified version, the first hinge 71 attached to the front door 30 and the left side door 60 is positioned below the second hinge 72 attached to the right side 50 and the rear 40.

[0087] Furthermore, in the modified example, the relationship between the distance Da between the first hinge 71 and the second hinge 72 during opening and closing differs from that of the structure in Figure 1. Specifically, in the modified example, when the front door section 30 and the left side door section 60 are closed, the distance Da is zero, and the end of the first cylindrical section 71b on the second hinge 72 side and the end of the second cylindrical section 72b on the first hinge 71 side are in contact. On the other hand, when the front door section 30 and the left side door section 60 are opened, the end of the first cylindrical section 71b on the second hinge 72 side moves away from the end of the second cylindrical section 72b on the first hinge 71 side.

[0088] Figures 21(a) to 21(d) show perspective views of a modified storage box enclosure according to one embodiment of the present invention when the door is open. Figures 22(a) to 22(d) show perspective views of a modified storage box enclosure according to one embodiment of the present invention when the door is closed. The opening and closing method of the modified storage box enclosure according to this embodiment will be described below.

[0089] In the state in which the front door portion 30 of the storage box housing 100 of this embodiment is closed, as shown in Figure 21(a), the end of the first cylindrical portion 71b on the side of the second hinge 72 and the end of the second cylindrical portion 72b on the side of the first hinge 71 are in contact at both the upper and lower parts of the door. Furthermore, the first nut 74 is spaced apart from the end of the third cylindrical portion 76b on the side of the first nut 74, and it is desirable that this spacing distance be greater than or equal to the length L of the side edge portion 12 of the lid portion 10.

[0090] To open the front door section 30, first remove the bolts and nuts from the holes 33 in the front door section 30, as shown in Figure 21(b).

[0091] Next, as shown in Figure 21(c), the second nut 75 welded to the bolt 73 is loosened. This also loosens the third nut 76 that is screwed onto the bolt 73, releasing the screw connection between the bolt 73 and the third cylindrical portion 76b, and the first nut 74 moves closer to the third nut 76. Consequently, the first cylindrical portion 71b of the first hinge 71 slides downward, and the door moves down. At this time, the end of the first cylindrical portion 71b on the second hinge 72 side gradually moves away from the end of the second cylindrical portion 72b on the first hinge 71 side, creating a separation distance Da.

[0092] Then, as shown in Figure 21(d), when the top of the front door section 30 has lowered to the point where it no longer touches the side edge 12 of the lid section 10, the front door section 30 is opened forward.

[0093] In this state, with the front door 30 open, the end of the first cylindrical portion 71b on the second hinge 72 side and the end of the second cylindrical portion 72b on the first hinge 71 side are separated by a distance Da at the top and bottom of the door. At this time, the distance Da is greater than or equal to the length L of the side edge 12 of the lid portion 10. On the other hand, the end of the second cylindrical portion 72b on the third nut 76 side and the end of the third cylindrical portion 76b on the second hinge 72 side are in contact.

[0094] Next, when closing the open front door 30 as shown in Figure 22(a), first, as shown in Figure 22(b), the front door 30 is closed so that it is inside the side edge 12 of the lid 10.

[0095] Next, as shown in Figure 22(c), the second nut 75 welded to the bolt 73 is tightened. This also tightens the third cylindrical portion 76b, which is screwable with the bolt 73, causing the bolt 73 and the third cylindrical portion 76b to screw together, and the first nut 74 to move away from the third nut 76. As a result, the first cylindrical portion 71b of the first hinge 71 slides upward, and the door rises. At this time, the end of the first cylindrical portion 71b on the second hinge 72 side gradually approaches the end of the second cylindrical portion 72b on the first hinge 71 side, and the separation distance Da decreases.

[0096] Then, as shown in Figure 22(d), once the top of the front door section 30 is raised to its highest point, a bolt is inserted into the hole 33 of the front door section 30 and tightened. At this time, at both the top and bottom of the door, the end of the first cylindrical section 71b on the second hinge 72 side is in contact with the end of the second cylindrical section 72b on the first hinge 71 side.

[0097] As described above, in this modified embodiment of the storage box housing 100 having the lid portion 10, when opening the front door portion 30, the front door portion 30 can be lowered by a separation distance Da (Da≧L) by releasing the screwed state of the bolt 73 and the third nut 76. Therefore, the front door portion 30 can be opened without the front door portion 30 hitting the side edge portion 12 of the lid portion 10.

[0098]

[13] Effects The storage box housing 100 according to this embodiment includes a lid portion 10 having a top plate portion 11 whose periphery extends outward beyond the outer peripheral edge of the upper surface of the frame F, and a side edge portion 12 that protrudes downward from the periphery of the top plate portion 11. The front door portion 30 and the left side door portion 60 are attached to the right side portion 50 and the rear portion 40, respectively, by an opening and closing mechanism 70, and the front door portion 30 and the left side door portion 60 are openable and closable doors. Thus, in this embodiment, when the front door portion 30 and the left side door portion 60 are closed, the upper parts of the front door portion 30 and the left side door portion 60 are covered by the side edge portion 12 of the lid portion 10.

[0099] Furthermore, the opening and closing mechanism 70 according to this embodiment includes a first hinge 71, a second hinge 72, a bolt 73, a first nut 74, a second nut 75, and a third nut 76. When the front door section 30 and the left side door section 60 are closed, the bolt 73 and the third nut 76 are screwed together.

[0100] In the storage box housing 100 according to this embodiment, when opening the front door 30 and the left side door 60, rotating the second nut 75 welded to the bolt 73 causes the bolt 73 to rotate as well, loosening the third nut 76 that was screwed onto the bolt 73. In other words, by gradually releasing the screwing between the bolt 73 and the third nut 76, the front door 30 and the left side door 60 can be lowered. As a result, the front door 30 and the left side door 60 can be opened without them hitting the side edge 12 of the lid 10. Thus, in this embodiment, in the storage box housing 100 having a lid 10, it is possible to open and close the doors without them hitting the side edge 12 while suppressing the intrusion of rainwater from above.

[0101] In the opening and closing mechanism 70 of the storage box housing 100 according to this embodiment, a second nut 75 is welded to a bolt 73, and a third nut 76 is attached to the side adjacent to the door and screwed onto the bolt 73. Therefore, when opening the front door 30 and the left side door 60 and lowering them downwards, the front door 30 and the left side door 60 can be supported by the second nut 75 and the third nut 76 welded to the bolt 73. This reduces the risk of the front door 30 and the left side door 60 suddenly falling down when lowering them when opening the doors.

[0102] In the storage box enclosure 100 according to this embodiment, the lid 10, bottom 20, front door 30, rear 40, right side 50, left side door 60, and heat shield 90 are each detachable assembly structures. Therefore, if a part of the storage box enclosure 100 deteriorates due to rust or the like, only the deteriorated part can be replaced. As a result, unlike storage box enclosures that are integrally formed by welding, it is not necessary to replace the entire enclosure, making it easy to replace parts, shortening working time, and reducing waste and thus lowering disposal costs. In this way, by being able to replace only the deteriorated parts that no longer maintain their waterproof function, economic benefits can also be improved.

[0103] Although embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
