[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, a door support 80, 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 that it can be opened and closed, and the left side door section 60 to the rear section 40 so that it can be opened and closed. The opening and closing mechanism 70 has a male first hinge 71 and a female second hinge 72.

[0019] The door support portion 80 is provided below the bottom surface of the frame F at the lower end of the opening and closing side of the front door portion 30 and the left side door portion 60.

[0020] The heat shield 90 is provided on the lid 10. This heat shield 90 protects the equipment inside the housing 100 from heat.

[0021] The frame F, lid 10, bottom 20, front door 30, rear 40, right side 50, left side door 60, opening / closing mechanism 70, door support 80, 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.

[0022] 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.

[0023] 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 front door portion 30 and the left side door portion 60 slide downward, 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.

[0024] 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.

[0025] [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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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 18).

[0030] 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 18).

[0031] [3] Opening and closing mechanism Figures 6(a) to 6(c) show a perspective view and a side view of the opening and closing mechanism of a storage box housing according to one embodiment of the present invention. Here, Figures 6(a) and 6(b) show the opening and closing mechanism with the front door closed, and Figure 6(c) 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.

[0032] As shown in Figures 6(a) and (b), the opening and closing mechanism 70 has a first hinge 71 and a second hinge 72. The first hinge 71 is a male hinge, and the second hinge 72 is a female hinge.

[0033] The first hinge 71 has a first plate-like portion 71a, a shaft mounting portion 71b, and a shaft portion 71c. The first plate-like 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 shaft mounting portion 71b is provided on the first plate-like portion 71a. The shaft portion 71c is provided on the shaft mounting portion 71b and protrudes from the shaft mounting portion 71b in the Z direction (downward in this embodiment). The shaft portion 71c is longer than the shaft portion of a typical hinge, for example, it is longer than the length L of the side edge portion 12, and is long enough to be inserted into the bearing portion 72b described later even when the door is closed.

[0034] The second hinge 72 has a second plate-like portion 72a and a bearing portion 72b. The second plate-like 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 bearing portion 72b is provided on the second plate-like portion 72a. This bearing portion 72b is fitted so as to slide downwards onto the shaft portion 71c of the hinge 71.

[0035] In the opening and closing mechanism 70 of this embodiment, when the door is closed, as shown in Figure 6(b), the end of the shaft mounting portion 71b on the second hinge 72 side and the end of the bearing portion 72b on the first hinge 71 side are spaced apart, and the shaft portion 71c is exposed. This spacing distance D is greater than or equal to the length L of the side edge portion 12 of the lid portion 10.

[0036] On the other hand, when opening the door, as shown in Figure 6(c), the shaft portion 71c of the first hinge 71 slides downward, causing the door to move down. At this time, the end of the shaft mounting portion 71b comes into contact with the end of the bearing portion 72b, the separation distance D becomes zero, and the downward sliding of the door stops.

[0037] 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 is welded to the right side portion 50 and the rear portion 40.

[0053] [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.

[0054] 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.

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.

[0056] 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.

[0057] [9] Door support section Figures 12(a) to 12(c) show a perspective view, a plan view, and a side view of the door support portion of a storage box enclosure according to one embodiment of the present invention. The structure of the door support portion of the storage box enclosure according to this embodiment will be described below.

[0058] As shown in Figures 12(a) to (c), the door support portion 80 is provided below the bottom surface of the frame F at the lower end of the opening / closing side of the front door portion 30 and the left side door portion 60 (the end opposite to the opening / closing mechanism 70 on the bottom surface portion 20 side). This door support portion 80 has a mounting portion 80a and protruding portions 80b and 80c.

[0059] The mounting portion 80a is provided with holes 81. Bolts 82 are inserted into these holes 81, and the mounting portion 80a is removably attached to the bottom surface of the frame F. However, the number and arrangement of the holes 81 are not limited to this figure and can be changed in various ways. Furthermore, the mounting portion 80a is not limited to being attached with bolts 82; for example, it can also be attached to the bottom surface of the frame F by welding.

[0060] The mounting portion 80a is, for example, L-shaped, following the shape of the corner of the frame F. However, the shape of the mounting portion 80a can be changed as appropriate.

[0061] The protruding portions 80b and 80c protrude outward from the mounting portion 80a beyond the bottom portion 20. The length Q of the protruding portions 80b and 80c in the protruding direction is defined as follows in relation to the angle θ described later. In other words, when the door is open, the length Q and angle θ of the protruding portions 80b and 80c are defined such that the door moves downward by the length L of the side edge portion 12 or more before the door opens by the length P of the top plate portion 11 and hits the lid portion 10.

[0062] In this embodiment, the shapes of the protrusions 80b and 80c are rectangular, but they can be changed in various ways.

[0063] As shown in Figure 12(c), the extension direction of the protrusions 80b and 80c is diagonally downward. Specifically, the angle θ of the extension direction of the protrusions 80b and 80c with respect to the horizontal direction (X or Y direction) of the bottom surface 20 (mounting portion 80a) is, for example, about 30 degrees to 60 degrees, preferably about 45 degrees.

[0064] In this type of door support 80, when the front door 30 and the left side door 60 are opened, the lower ends of the front door 30 and the left side door 60 slide along the protrusions 80b and 80c as the front door 30 and the left side door 60 slide downward (from the lid 10 towards the bottom 20). As a result, when the front door 30 and the left side door 60 are opened, the protrusions 80b and 80c support the front door 30 and the left side door 60 as they slide, preventing the front door 30 and the left side door 60 from suddenly falling downward.

[0065] In this embodiment, the extension direction of the protruding portions 80b and 80c in the housing 100 is diagonally downward, but is not limited to this. For example, the extension direction of the protruding portions 80b and 80c may be parallel (θ=0 degrees) to the horizontal direction (X direction or Y direction) of the bottom surface portion 20 (mounting portion 80a). Here, the length Q of the protruding portions 80b and 80c in the protruding direction is required to be less than the length P that extends outward from the outer peripheral edge FE of the top plate portion 11.

[0066] In this case, when the bolts and nuts in the holes 33 and 63 of the front door 30 and the left side door 60 are removed in order to open them, the horizontally extending protrusions 80b and 80c prevent the front door 30 and the left side door 60 from suddenly falling down. Thus, the angle θ in the extending direction of the door support portion 80 in this embodiment may be 0 degrees ≤ θ < 90 degrees.

[0067] Furthermore, in the storage box housing 100 according to this embodiment, the front door portion 30 and the left side door portion 60 have a door structure, and therefore door support portions 80 are provided at the lower ends of these front door portion 30 and left side door portion 60, but the invention is not limited to this. The position of the doors of the storage box housing 100 can be changed as appropriate, and for example, if the right side portion 50 has a door structure, it is also possible to provide a door support portion 80 at the lower end of the opening / closing side of the right side portion 50.

[0068] Furthermore, in the housing casing 100 according to this embodiment, it is also possible to omit the door support portion 80.

[10] Heat shield Figures 13(a) to 13(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 13(d) is a side view from the direction D-D' of Figure 13(c), and Figure 13(e) is a side view from the direction E-E' of Figure 13(c). The structure of the heat shield plate for the housing casing according to this embodiment will be described below.

[0070] As shown in Figures 13(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.

[0071] 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 18).

[0072] 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.

[0073]

[11] Frame Figures 14(a) to 14(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 15(a) to 15(h), 16(a) to 16(h), and 17(a) to 17(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 18 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.

[0074] As shown in Figures 14(a) to (f), 15(a) to (h), 16(a) to (h), and 17(a) to (h), the housing-type frame F of this embodiment is composed of frame components F1 to F12.

[0075] 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.

[0076] As shown in Figure 18, 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.

[0077] 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.

[12] Opening and closing method Figures 19(a) to 19(c) show perspective views of the open and closed state of the door of a storage box enclosure according to one embodiment of the present invention. Figure 20 shows a perspective view from the rear when the door of the storage box enclosure according to one embodiment of the present invention is open. Figures 21(a) to 21(c) show schematic diagrams of the opening and closing mechanism in the open and closed state of the door of the storage box enclosure according to one embodiment of the present invention. The method for opening and closing the door of the storage box enclosure according to this embodiment will be described below.

[0079] First, as shown in Figures 19(a) and 21(a), when the front door 10 and left side door 60 of the housing 100 of this embodiment are closed, the end of the shaft mounting portion 71b on the second hinge 72 side and the end of the bearing portion 72b on the first hinge 71 side are spaced apart, and a part of the shaft portion 71c is exposed. This spacing distance D is greater than or equal to the length L of the side edge portion 12 of the lid portion 10.

[0080] In this embodiment, the storage box housing 100 has a male hinge, a first hinge 71 attached to the door section (front door section 30 and left side door section 60), and a second hinge 72 attached to the side adjacent to the door section (right side section 50 and rear section 40). The first hinge 71 is positioned above the second hinge 72 (towards the lid section 10), and its shaft portion 71c faces downward (towards the bottom section 50).

[0081] To open the front door section 30 and the left side door section 60, first remove the bolts and nuts from the holes 33 and 63 in the front door section 30 and the left side door section 60.

[0082] As a result, as shown in Figures 19(b) and (c), Figure 20, and Figures 21(b) and (c), the front door section 30 and the left side door section 60 move downward towards the bottom section 20. At this time, the door support section 80 supports the front door section 30 and the left side door section 60, preventing them from suddenly dropping downward.

[0083] In this embodiment of the storage box housing 100, when the front door 10 and the left side door 60 are opened, as shown in Figures 21(a) to (c), when the front door 30 and the left side door 60 are closed, the separation distance D is greater than or equal to the length L of the side edge 12 of the lid 10. However, when the front door 30 and the left side door 60 are opened, the end of the shaft mounting portion 71b comes into contact with the end of the bearing portion 72b, and the front door 10 and the left side door 60 stop moving downwards. As a result, the separation distance D becomes zero.

[0084] As described above, in the storage box housing 100 having the lid portion 10 of this embodiment, when the front door portion 30 and the left side door portion 60 are opened, the shaft portion 71c of the first hinge 71 rotates and slides downward within the bearing portion 72b of the second hinge 72, causing the front door portion 30 and the left side door portion 60 to move downward by a separation distance D (D≧L). Therefore, the front door portion 30 and the left side door portion 60 can be opened without them hitting the side edge portion 12 of the lid portion 10.

[0085]

[12] Variant Figures 22(a) to (c) show perspective views of the open and closed states of the door portion of a modified storage box housing according to one embodiment of the present invention. The structure of the modified storage box housing according to this embodiment will be described below.

[0086] As shown in Figures 22(a) to (c), in the modified version of the storage box housing 100 of this embodiment, the difference from the structure in Figure 1 is that the second hinge 72 is located above the first hinge 71 on the lid 10 side. In other words, in the modified opening and closing mechanism 70, the first hinge 71, which is a male hinge attached to the front door 30, is positioned below the second hinge 72, which is a female hinge attached to the right side 50. As a result, the shaft portion 17c of the first hinge 71 faces upward and protrudes toward the lid 10 side.

[0087] Furthermore, in the modified example, the relationship between the separation distance D' during opening and closing differs from that of the structure in Figure 1. Specifically, in the modified example, when the front door 30 and the left side door 60 are closed, the separation distance D' is zero, and the end of the shaft mounting portion 71b is in contact with the end of the bearing portion 72b. On the other hand, when the front door 30 and the left side door 60 are opened, the end of the shaft mounting portion 71b gradually moves away from the end of the bearing portion 72b.

[0088] Furthermore, in the opening and closing mechanism 70 shown in Figures 22(a) to (c), a female second hinge 72' may be added below the first hinge 71. Specifically, in the opening and closing mechanism 70 when the door is closed, the female second hinge 72 attached to the right side portion 50, the male first hinge 71 attached to the front door portion 30, and the female second hinge 72' attached to the right side portion 50 are arranged in that order from top to bottom, and the first hinge 71 and the second hinge 72' may have a separation distance D. In this case, the separation distance D is greater than or equal to the length L of the side edge portion 12 of the lid portion 10.

[0089] Here, it is desirable that the length of the shaft portion 71c of the first hinge 71 be approximately the same as the length of the bearing portion 72b of the second hinge 72, and that when the door is closed, the tip of the upward-facing shaft portion 71c of the first hinge 71 reaches the upper surface of the bearing portion 72b of the second hinge 72. Furthermore, it is desirable that the first hinge 71 be provided with an additional shaft portion 71c' that protrudes downward (towards the second hinge 72'), and that when the door is closed, this shaft portion 71c' is inserted into the bearing portion 72b' of the second hinge 72' while maintaining a separation distance D.

[0090] In this structure, as in Figure 1, when the front door section 30 and the left side door section 60 are closed, the distance D' between the first hinge 71 and the second hinge 72 is zero, but the distance D between the first hinge 71 and the second hinge 72' is greater than or equal to the length L of the side edge 12 of the lid section 10. On the other hand, when the front door section 30 and the left side door section 60 are open, the end of the shaft mounting portion 71b of the first hinge 71 gradually moves away from the end of the bearing portion 72b of the second hinge 72, creating a distance D', but the end of the shaft mounting portion 71b of the first hinge 71 is in contact with the end of the bearing portion 72b of the second hinge 72', and the distance D becomes zero. In this way, when the door is opened, the second hinge 72' acts as a stopper to prevent the door from sliding down.

[0091]

[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.

[0092] Furthermore, the opening and closing mechanism 70 according to this embodiment has a male first hinge 71 and a female second hinge 72. When the front door portion 30 and the left side door portion 60 are closed, the end of the shaft mounting portion 71b on the second hinge 72 side and the end of the bearing portion 72b on the first hinge 71 side are spaced apart (spaced distance D ≥ length L of the side edge portion 12 of the lid portion 10), and the shaft portion 71c of the first hinge 71 is slidably fitted into the bearing portion 72b of the second hinge 72.

[0093] In the storage box housing 100 according to this embodiment, when opening the front door 30 and the left side door 60, the shaft portion 71c of the first hinge 71 slides downward within the bearing portion 72b of the second hinge 72, causing the front door 30 and the left side door 60 to move downward. As a result, the front door 30 and the left side door 60 can be opened without them hitting the side edge portion 12 of the lid portion 10. Thus, in this embodiment, in the storage box housing 100 having a lid portion 10, it is possible to open and close the doors without them hitting the side edge portion 12 while suppressing the intrusion of rainwater from above.

[0094] In this embodiment, the storage box housing 100 is provided with a door support portion 80 below the bottom surface of the frame F. Therefore, when the front door portion 30 and the left side door portion 60 are opened and slide downwards, the door support portion 80 can support the front door portion 30 and the left side door portion 60. This allows the front door portion 30 and the left side door portion 60 to open smoothly and reduces the risk of the front door portion 30 and the left side door portion 60 suddenly falling down.

[0095] In the storage box housing 100 according to this embodiment, the lid 10, bottom 20, front door 30, rear 40, right side 50, left side door 60, door support 80, and heat shield 90 are each detachable assembly structures. Therefore, if a part of the storage box housing 100 deteriorates due to rust or the like, only the deteriorated part can be replaced. As a result, unlike storage box housings that are integrally formed by welding, it is not necessary to replace the entire housing, so parts can be easily replaced, work time can be shortened, and the amount of discarded parts can be reduced, 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.

[0096] 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.
