Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the cabinet described in Patent Document 1, since the top plate member is formed by bending the four sides of the front, rear, left, and right, if the bending accuracy of the top plate member is poor, the cabinet is likely to be distorted, while if high accuracy is required for the bending accuracy, it will lead to high costs. In addition, it is also conceivable to stack and use a plurality of cabinets in the vertical direction. Therefore, a connecting portion such as a bolt hole for connecting adjacent cabinets vertically is provided on the upper surface or the lower surface of the cabinet, but there is a concern that the strength of the cabinet may be reduced by providing such a connecting portion.

[0005] Therefore, the present invention has been made in view of the above problems, and aims to provide a cabinet having a simple structure of the top plate member and sufficient strength even if a connecting portion is provided.

Means for Solving the Problems

[0006] To achieve the above objective, the invention described in claim 1 of the present invention is a cabinet comprising a box body having left and right sides and a back, and openings on the top, front and bottom, a top plate member attached to the box body and closing the top opening of the box body, and a bottom plate member attached to the box body and closing the bottom opening of the box body, wherein front plate portions are provided at the front ends of both the left and right sides of the box body, and tongue pieces are provided at the upper and lower ends of the sides and back of the box body, and are folding inward of the box body, and further, a gap is provided between the upper end of the front plate portion and the tongue piece on the top side of the box body into which the top plate member can be inserted, and a gap is provided between the lower end of the front plate portion and the tongue piece on the bottom side of the box body into which the bottom plate member can be inserted, and the top plate member and the bottom plate member are attached to the box body in a state where they are inserted through the corresponding gaps. The invention described in claim 2 is characterized in that, in the invention described in claim 1, connecting portions for connecting two stacked cabinets are provided on the tongue on the upper side of the box body, the tongue on the lower side of the box body, the portion of the top plate member that overlaps with the tongue vertically, and the portion of the bottom plate member that overlaps with the tongue vertically. The invention described in claim 3 is characterized in that, in the invention described in claim 1 or 2, a lower front plate portion is provided at the front end of the bottom plate member, the bottom plate member is attached to the box body with both left and right ends of the lower front plate portion in contact with the front surfaces of the left and right front plate portions, and drainage portions are provided at the upper edges of both left and right ends of the lower front plate portion, which slope downward toward the left and right. [Effects of the Invention]

[0007] According to the present invention, front panels are provided at the front ends of both the left and right sides of the box body, folded inward from the box body. Tongues are provided at the upper and lower ends of the sides and back of the box body, folded inward from the box body. Furthermore, a gap is provided between the upper end of the front panel and the tongue on the upper side of the box body into which a top plate member can be inserted, and a gap is provided between the lower end of the front panel and the tongue on the lower side of the box body into which a bottom plate member can be inserted. The top plate member and the bottom plate member are attached to the box body by being inserted through the corresponding gaps. Therefore, the structure of the top plate member and the like can be simplified compared to conventional designs, making it possible to create a cabinet that is less prone to distortion while keeping manufacturing costs down. Furthermore, according to the invention described in claim 2, connecting parts for connecting two stacked cabinets are provided on the tongue on the upper side of the box body, the tongue on the lower side of the box body, the portion of the top plate member that overlaps with the tongue vertically, and the portion of the bottom plate member that overlaps with the tongue vertically. In other words, since the connecting parts are provided in the double-layered structure, the cabinet can have sufficient strength despite the presence of the connecting parts. Furthermore, according to the invention described in claim 3, a lower front plate portion is provided at the front end of the bottom plate member, and the bottom plate member is attached to the box body with both left and right ends of the lower front plate portion in contact with the front surfaces of the left and right front plate portions. Additionally, drainage portions are provided at the upper edges of both left and right ends of the lower front plate portion, which slope downward outward in the left-right direction. Therefore, water droplets that flow down the surface of the front plate portion and reach the upper edge of the lower front plate portion will not remain on the upper edge of the lower front plate portion but will flow off, thereby improving the rust prevention properties of the bottom plate member.

[0009] The following describes in detail, based on the drawings, a cabinet that is one embodiment of the present invention.

[0010] Figure 1 is a perspective view illustrating the cabinet 1 installed on the stand 30. Figure 2 is a perspective view illustrating the main body 2 of the cabinet 1. Figure 3 is a perspective view illustrating the main body 2 in a disassembled state. Figure 4 is an enlarged view illustrating the upper right end of the front of the box body 4. Figure 5 is an enlarged view illustrating the lower right end of the front of the box body 4. Figure 6 is an enlarged view illustrating area A in Figure 2. Figure 7 is an illustration illustrating the vertical cross-section of the cabinet 1 in the area related to area A. Figure 8 is an illustration illustrating the state in which two cabinets 1, 1 are stacked vertically and used.

[0011] Cabinet 1 is used, for example, as a parcel receiving box, and comprises a rectangular box-shaped main body 2 that opens to the front, and a door body 3 that opens and closes the front opening of the main body 2. The main body 2 also comprises a box body 4 having left and right sides and a back, a top plate member 5 attached to the box body 4, and a bottom plate member 6 attached to the box body 4. The box body 4 is formed by bending a metal plate into a U-shape that opens to the front when viewed from above, thereby creating the left and right sides and back. The upper ends of both sides and the back are also bent inward. Upper bolt holes 7, 7·· are drilled in these upper bent parts, and these serve as upper connecting pieces 8 for connecting two cabinets 1, 1 to each other with bolts (not shown) when two cabinets 1, 1 are stacked vertically. On the other hand, the lower ends of both sides and the back of the box body 4 are also bent inward, similar to the upper end, and the same lower bolt holes 9, 9, etc. as the upper bolt holes 7, 7, etc. are drilled therein, and these serve as lower connecting pieces 10 for connecting stacked cabinets 1, 1 with bolts.

[0012] Furthermore, the front ends of both sides of the box body 4 are provided with left and right front panel portions 11, 11 that are folded inward in the left-right direction, and left and right drainage portions 12 are provided by folding the tips of the left and right front panel portions 11, 11 forward again in the left-right direction and then folding them back outward in the left-right direction. In addition, upper gaps 13, 13 are provided between the upper ends of the left and right front panel portions 11, 11 and the upper connecting piece 8 into which the top plate member 5 can be inserted. Also, lower gaps 14, 14 are provided between the lower ends of the left and right front panel portions 11, 11 and the lower connecting piece 10 into which the bottom plate member 6 can be inserted. Note that 32 is a hinge for attaching the door body 3 to the main body 2 so that it can open to one side.

[0013] The top plate member 5 and the bottom plate member 6 are made of rectangular metal plates in a top view, having approximately the same width from left to right as the back of the box body 4. Connecting holes 15, 15, etc. are drilled in the four corners of the top plate member 5 and the bottom plate member 6 (where the top plate member 5 and the upper connecting piece 8 overlap vertically, and where the bottom plate member 6 and the lower connecting piece 10 overlap vertically) through which bolts are inserted when connecting stacked cabinets 1, 1. In addition, the front end of the bottom plate member 6 is provided with a lower front plate portion 16 that is bent upward, and a lower drainage portion 17 is provided by bending the tip of the lower front plate portion 16 forward again and then folding it downward. Furthermore, the upper edges of the lower front panel 16 at both the left and right ends (where they overlap front and rear when the bottom panel 6 is attached to the box body 4 as described later) are sloped downward toward the left and right outwards, and these sloped sections serve as drainage sections 18 for draining water droplets that have dripped onto the upper edge of the lower front panel 16. On the other hand, the front end of the top panel 5 is provided with an upper front panel 19 that is bent downward, and an upper drainage section 20 is provided by bending the tip of the upper front panel 19 forward again and then folding it upward. Note that when the top panel 5 is turned upside down, it becomes the bottom panel 6.

[0014] Then, in assembling the cabinet 1 as described above, first, the rear end of the bottom plate member 6 is inserted into the lower gaps 14, 14 from the front side of the box body 4, and the bottom plate member 6 is pushed backward along the lower connecting pieces 10, 10. When the lower front plate portion 16 comes into contact with the front surfaces of the left and right front plate portions 11, 11, the bottom plate member 6 and the box body 4 are integrated by spot welding the lower front plate portion 16 to the left and right front plate portions 11, 11. Next, the box body 4 is turned upside down, and the rear end of the upside-down top plate member 5 is inserted into the upper gaps 13, 13 from the front side of the box body 4, and the top plate member 5 is pushed backward along the upper connecting pieces 8, 8. When the upper front plate portion 19 comes into contact with the front surfaces of the left and right front plate portions 11, 11, the top plate member 5 and the box body 4 are integrated by spot welding the upper front plate portion 19 to the left and right front plate portions 11, 11, and the main body 2 is assembled. Finally, return the main body 2 to its original position so that the top panel 5 is positioned on top, and then attach the door 3 to the main body 2 to complete the assembly of the cabinet 1.

[0015] In the assembled cabinet 1, the front opening of the main body 2 is surrounded by the upper water cutoff part 20, the left and right water cutoff parts 12, 12, and the lower water cutoff part 17. The drainage parts 18, 18 of the lower front plate part 16 are exposed outside the lower water cutoff part 17 in the left-right direction at the left and right lower end parts of the front surface of the main body 2. Therefore, the water droplets flowing down the surfaces of the left and right front plate parts 11, 11 and reaching the lower front plate part 16 do not stay on the upper edge of the lower front plate part 16, but flow down from the upper surface of the lower front plate part 16 by the drainage parts 18, 18.

[0016] Furthermore, the cabinet 1 can be installed on the gantry 30 by embedding an anchor bolt (not shown) from the connecting holes 15, 15... of the bottom plate member 6 through the lower bolt holes 9, 9... In addition, it is also possible to stack and use another cabinet 1 on the cabinet 1. In that case, with an elastic synthetic resin plate 31 (such as a rubber plate) interposed between the cabinets 1, 一, insert bolts from the connecting holes 15, 15... of the bottom plate member 6 of the upper cabinet 1 into the lower bolt holes 9, 9... of the lower connecting piece 10 of the upper cabinet 1, the upper bolt holes 7, 7... of the upper connecting piece 8 of the lower cabinet 1, and the connecting holes 15, 15... of the top plate member 5 of the lower cabinet 1, and use nuts or the like to connect the upper and lower cabinets 1, 1. For the cabinet 1 used alone or the cabinet 1 located at the uppermost stage, install a separate roof member on the cabinet 1 or the like to prevent water from entering from the upper bolt holes 7, 7... and the connecting holes 15, 15... of the top plate member 5.

[0017] According to the cabinet 1 having the above configuration, front plate portions 11, 11 that are bent inward of the box body 4 are provided at the front ends of both left and right side surfaces of the box body 4, and upper connecting pieces 8 and lower connecting pieces 10 that are bent inward of the box body 4 are provided at the upper and lower ends of the side surface and the back surface of the box body 4. Further, upper gaps 13 into which the top plate member 5 can be inserted are provided between the upper ends of each front plate portion 11 and the upper connecting piece 8, and lower gaps 14 into which the bottom plate member 6 can be inserted are provided between the lower ends of each front plate portion 11 and the lower connecting piece 10. And the top plate member 5 is attached in a state of being inserted into the box body 4 from the upper gap 13, and the bottom plate member 6 is attached in a state of being inserted into the box body 4 from the lower gap 14. Therefore, the structure of the top plate member and the like can be simplified compared with the prior art, and the cabinet 1 can be made with a suppressed manufacturing cost and less likely to generate distortion.

[0018] Also, upper bolt holes 7, lower bolt holes 9, connecting holes 15, etc. for connecting two stacked cabinets 1, 1 are provided at the upper connecting piece 8, the lower connecting piece 10, the portion of the top plate member 5 that overlaps the upper connecting piece 8 vertically, and the portion of the bottom plate member 6 that overlaps the lower connecting piece 10 vertically. That is, since components related to the connection between the cabinets 1, 1 are provided at the double-structured portions, the cabinet 1 can have sufficient strength despite the provision of the upper bolt holes 7, the lower bolt holes 9, etc.

[0019] Furthermore, a lower front plate portion 16 bent upward is provided at the front end of the bottom plate member 6. The bottom plate member 6 is attached to the box body 4 with the left and right ends of the lower front plate portion 16 abutting against the front surfaces of the left and right front plate portions 11, 11, and drainage portions 18 that slope downward outward in the left-right direction are provided at the upper edges of the left and right ends of the lower front plate portion 16, respectively. Therefore, water droplets that flow down the surfaces of the front plate portions 11, 11 and reach the upper edge of the lower front plate portion 16 will flow down without staying on the upper edge of the lower front plate portion 16 as it is, so that the rust prevention property of the bottom plate member 6 can be improved.

[0020] It should be noted that the cabinet according to the present invention is not limited in any way to the embodiments described above, and the overall configuration of the cabinet, as well as the box body, top plate member, bottom plate member, and the configuration related to connecting cabinets to each other, can be modified as needed.

[0021] For example, in the above embodiment, a box body having left and right sides and a back is formed by bending a metal plate, but a box body may also be formed by combining multiple metal plates. Furthermore, in the above embodiment, the top plate member and the bottom plate member are the same member, and the top plate member becomes the bottom plate member when inverted. However, there is no problem in configuring both members as separate members with different shapes or other characteristics. Furthermore, the design can be modified as appropriate regarding whether or not to provide a drainage section in the bottom plate member, as well as the position and number of connecting sections.
