Description

[Technical field]

[0001] The present disclosure relates to a delivery box. [Background technology]

[0002] Conventionally, there is a delivery box described in Patent Document 1. This delivery box has an opening on the front and is equipped with a resin main body formed integrally with top and bottom faces, left and right side faces, and a back face, an opening door connected to the main body to allow the opening to be opened and closed freely, and a locking mechanism provided on the opening door. Since the top and bottom faces, left and right side faces, and back face are integrally molded, this delivery box is easy to assemble and mass-produce. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-99454 A Summary of the Invention [Problem to be solved by the invention]

[0004] If a resin body is used in which the top, bottom, left and right sides, and back are molded as one unit, the rigidity of the delivery box may be reduced, making the delivery box more susceptible to damage. In addition, in recent years, the variety of products being delivered has increased, and the packages being delivered have a wide variety of shapes, so there are cases where it is preferable to place the delivery box vertically and cases where it is preferable to place it horizontally. However, the delivery box has a problem in that it cannot be flexibly changed in position depending on the purpose.

[0005] Therefore, an object of the present disclosure is to provide a delivery box that has an integrally molded resin main body that is easy to assemble, has high rigidity, and allows for high freedom of placement. [Means for solving the problem]

[0006] In order to solve the above problems, the delivery box of the present disclosure comprises a box body made of a one-piece resin molded product that defines an internal chamber that is open at the front in the depth direction, a reinforcing frame that is fitted and attached to the opening edge portion at the front end of the box body, a door that is attached to the reinforcing frame via a hinge, and a locking device that is attached to the door and allows the door to be selectively locked or unlocked, and the box body has a side fitting and fixing portion for fitting and fixing a first reinforcing plate that extends along the inner surface of the side panel portion of the box body, and a bottom fitting and fixing portion for fitting and fixing a second reinforcing plate that extends along the inner surface of the bottom panel portion of the box body, and comprises at least one of the first reinforcing plate fixed to the side fitting and fixing portion and the second reinforcing plate fixed to the bottom fitting and fixing portion.

[0007] The side plate portion and bottom plate portion refer to the side plate portion and bottom plate portion when the delivery box is in use. Therefore, one of the two side plate portions that exist when the delivery box is placed vertically becomes the bottom plate portion when the delivery box is placed horizontally, and the other of the two side plate portions becomes the top plate portion when the delivery box is placed horizontally. Also, the bottom plate portion and top plate portion when the delivery box is placed vertically become two side plate portions when the delivery box is placed vertically. Effect of the Invention

[0008] According to the delivery box of the present disclosure, a box body made of a resin integrally molded product that defines an internal chamber that opens at the front side in the depth direction is adopted, so that the assembly can be made good and the mass production is excellent. In addition, since the delivery box includes at least one of a first reinforcing plate extending along the inner surface of the side plate portion of the box body and a second reinforcing plate extending along the inner surface of the bottom plate portion of the box body, the rigidity can be increased. In addition, since the box body has a side-side fitting and fixing portion for fitting and fixing the first reinforcing plate extending along the inner surface of the side plate portion of the box body, and a bottom-side fitting and fixing portion for fitting and fixing the second reinforcing plate extending along the inner surface of the bottom plate portion of the box body, the delivery box can be flexibly arranged both vertically and horizontally. For example, the lower surface of the internal chamber can be formed by the upper surface of the second reinforcing plate whether the delivery box is placed vertically or horizontally. Therefore, the degree of freedom in the arrangement of the delivery box can be increased. [Brief description of the drawings]

First, in order to explain the mounting structure of the first and second reinforcing plates 60 and 70, the structure of the box body 10, the structure of the reinforcing frame 25, and the structure of the first and second reinforcing plates 60 and 70 will be described.

[0015] The box body 10 has a substantially rectangular parallelepiped shape and defines an internal chamber (luggage chamber) 2 that is open only on the front side in the X direction. The internal chamber 2 has a substantially rectangular parallelepiped box shape capable of accommodating luggage (not shown). The box body 10 is an integrally molded resin product, and is formed from resin such as polypropylene (PP) or acrylonitrile styrene acrylate (ASA). FIG. 3 is a perspective view of the box body 10 as viewed from the front side in the X direction. The box body 10 has a structure that is substantially plane-symmetrical with respect to a first plane R (see FIG. 14) that passes through the midpoint in the Y direction and includes the X direction and the Z direction, and also has a structure that is substantially plane-symmetrical with respect to a second plane S (see FIG. 14) that passes through the midpoint in the Z direction and includes the X direction and the Y direction.

[0016] In the following, first, a structure located on the left side of the first plane R when viewed from the front side will be described. Since the box body 10 has a structure that is approximately flush with the first plane R, a description of a structure located on the right side of the first plane R when viewed from the front side will be omitted. As shown in FIG. 3, the box body 10 has one or more elongated first recesses 16 extending in the Z direction at the rear end in the X direction and both ends in the Y direction, and in this embodiment, a plurality of first recesses 16 are provided in multiple stages in the Z direction on the rear side in the X direction and both sides in the Y direction. The box body 10 has a first plate-like protruding portion 17 in the shape of an elongated flat plate protruding from the inner surface 14a of the rear plate portion 14 to the front side in the X direction. The first plate-like protruding portion 17 is approximately parallel to the inner surface 12a of the side plate portion 12 and extends in the Z direction.

[0017] The box body 10 further has a plurality of plate-shaped first partitions 18. Each of the first partitions 18 has a flat plate shape and protrudes from the inner surface 14a of the rear plate 14 to the front side in the X direction. Each of the first partitions 18 is approximately parallel to a plane that is approximately perpendicular to the first plate-shaped protruding portion 17, and is approximately parallel to the inner surface 19a of the top plate 19. The plurality of first partitions 18 includes an upper partition 18a that connects the upper end of the first plate-shaped protruding portion 17 to the inner surface 12a of the side plate 12, a lower partition 18b that connects the lower end of the first plate-shaped protruding portion 17 to the inner surface 12a of the side plate 12, and one or more intermediate partitions 18c that are spaced apart in the Z direction on both the upper partition 18a and the lower partition 18b. Each first recess 16 is defined by the inner surface 12a of the side plate portion 12, the inner surface 14a of the rear plate portion 14, the first plate-shaped protruding portion 17, and two partition portions 18 adjacent to each other in the Z direction.

[0018] The box body 10 further has a plurality of plate-shaped first reinforcing plate guides 21. The first reinforcing plate guides 21 are elongated protrusions protruding in the Y direction from the inner surface 12a of the side plate 12, and extend in the X direction. The first reinforcing plate guides 21 face the intermediate partition 18c at an interval in the X direction, and are provided at substantially the same Z direction position as the intermediate partition 18c. The first reinforcing plate guides 21 have a recess 21a penetrating in the Z direction on the front side and on the outer side in the Y direction (the side plate 12 side in the Y direction). In this embodiment, the box body 10 has two intermediate partitions 18c and two first reinforcing plate guides 21, but the number of intermediate partitions 18c and first reinforcing plate guides 21 is not limited to this.

[0019] The box body 10 further has a plurality of elongated second recesses 23 extending in the Y direction at the rear end in the X direction and the lower end in the Z direction. The plurality of second recesses 23 are arranged at intervals in the Y direction. Each second recess 23 is defined by the inner surface 15a of the bottom plate portion 15, a second plate-like protruding portion 26, and a pair of second partition portions 27a, 27b. In detail, the second plate-like protruding portion 26 has an elongated flat plate shape, protrudes from the inner surface 14a of the rear plate portion 14 to the front side in the X direction substantially parallel to the inner surface 15a of the bottom plate portion 15, and extends in the Y direction. In addition, the pair of second partition portions 27a, 27b are arranged at intervals in the Y direction. Each partition portion 27a, 27b has a flat plate shape, and protrudes from the inner surface 14a of the rear plate portion 14 to the front side in the X direction substantially parallel to the inner surface 12a of the side plate portion 12. One second partition portion 27a connects the inner surface 12a to the left end of the second plate-shaped protrusion 26 in the Y direction, and the other second partition portion 27b connects the inner surface 12a to the right end of the second plate-shaped protrusion 26 in the Y direction.

[0020] The box body 10 further has a plurality of plate-shaped second reinforcing plate guide portions 28. The second reinforcing plate guide portions 28 protrude in the Z direction from the inner surface 15a of the bottom plate portion 15 and extend in the X direction. The second reinforcing plate guide portions 28 face the second partition portions 27a, 27b at an interval in the X direction, and are provided at substantially the same position in the Y direction as the second partition portions 27a, 27b.

[0021] Although not described in detail, box body 10 has a plurality of elongated recesses (not shown) at its rear end in the X direction and its upper end in the Z direction, and has a plurality of plate-shaped reinforcing plate guide portions (not shown) protruding in the Z direction from inner surface 19a of top plate portion 19. Since box body 10 has a structure that is approximately plane-symmetrical with respect to second plane S (see FIG. 14), the structure of the plurality of recesses is approximately the same as the structure of the plurality of second recesses 23, and the structure of the plurality of reinforcing plate guide portions is approximately the same as the structure of the plurality of second reinforcing plate guide portions 28.

[0022] In addition, a case has been described in which a plurality of first recesses 16 share a common first plate-shaped protruding portion 17, and intermediate partition portion 18c partitions adjacent first recesses 16. In addition, a case has been described in which a portion of each of a plurality of second recesses 23 is defined by a second plate-shaped protruding portion 26 different from each other, and a pair of second partition portions 27a, 27b defines only a portion of the inner surface of one second recess 23. However, the first recess located on the rear side in the X direction and on both sides in the Y direction of the vertically placed delivery box may have a structure similar to the above-mentioned second recess 23, and conversely, the second recess located on the rear side in the X direction and on the lower side in the Z direction of the vertically placed delivery box may have a structure similar to the above-mentioned first recess 16.

[0023] Next, the structure of the reinforcing frame 25 will be described. The reinforcing frame 25 is also an integrally molded resin product, similar to the box body 10, and is formed of resin such as polypropylene (PP) or acrylonitrile styrene acrylate (ASA). Referring to FIG. 2, the reinforcing frame 25 is press-fitted and fixed to the opening edge 6a on the inner surface of the front end 6 of the box body 10. FIG. 4 is a perspective view of the reinforcing frame 25 as seen from the rear side in the X direction and as seen from the inner chamber 2 (see FIG. 1) side. As shown in FIG. 4, the reinforcing frame 25 is substantially symmetrical with respect to a plane Q that passes through the center in the Z direction and includes the X direction and the Y direction.

[0024] The reinforcing frame 25 has one or more elongated third recesses 33 extending in the Z direction on the rear side in the X direction and on both ends in the Y direction, and in this embodiment, the multiple third recesses 33 are arranged in three stages in the Z direction on the rear side in the X direction and on both sides in the Y direction. Since the structure of the multiple third recesses 33 is the same on both sides in the Y direction, the structure of the third recesses 33 on the right side in the Y direction on the paper surface of Fig. 4 will be described below, and a description of the structure of the third recesses 33 on the left side in the Y direction on the paper surface of Fig. 4 will be omitted.

[0025] The reinforcing frame 25 has a third plate-shaped protruding portion 37 having an elongated flat plate shape protruding from the rear side in the X direction to the rear side in the X direction. The third plate-shaped protruding portion 37 is substantially parallel to a plane including the X direction and the Z direction, and extends in the Z direction. The reinforcing frame 25 further has a plurality of plate-shaped third partitioning portions 38. Each of the third partitioning portions 38 has a flat plate shape, and protrudes outward in the Y direction from the outer surface of the third plate-shaped protruding portion 37 in the Y direction. Each of the third partitioning portions 38 is substantially perpendicular to the third plate-shaped protruding portion 37.

[0026] The third partitions 38 include an upper partition 38a protruding outward in the Y direction from an upper end of the third plate-shaped protruding portion 37, a lower partition 38b protruding outward in the Y direction from a lower end of the third plate-shaped protruding portion 37, and one or more intermediate partitions 38c arranged at intervals in the Z direction on both the upper partition 38a and the lower partition 38b. Each third recess 33 is defined by the inner surface (rear side surface) 25a of the reinforcing frame 25, the third plate-shaped protruding portion 37, and two third partitions 38 adjacent to each other at an interval in the Z direction. Each third recess 33 opens outward in the Y direction and rearward in the X direction. There are the same number of third recesses 33 as there are first recesses 16 (see FIG. 3). With the reinforcing frame 25 fitted and fixed to the box body 10, the opening on the front side in the X direction of the first recess 16 substantially faces the opening on the rear side in the X direction of the third recess 33 with a gap in the X direction.

[0027] The reinforcing frame 25 further has a plurality of elongated fourth recesses 43 extending in the Y direction at a rear end in the X direction and a lower end in the Z direction. The plurality of fourth recesses 43 are arranged at intervals in the Y direction. Each fourth recess 43 is defined by an inner surface 25a of the reinforcing frame 25, a fourth plate-shaped protruding portion 46, and a pair of fourth partition portions 47a, 47b. Each fourth recess 43 opens to the rear side in the X direction and to the lower side in the Z direction.

[0028] The fourth plate-like protruding portion 46 has a long and narrow flat plate shape, protrudes from the inner surface 25a of the reinforcing frame 25 to the front side in the X direction and extends in the Y direction substantially parallel to a plane including the X direction and the Y direction. The pair of fourth partitions 47a, 47b are arranged at an interval in the Y direction. Each of the fourth partitions 47a, 47b has a flat plate shape and extends substantially parallel to a plane including the X direction and the Z direction. One of the fourth partitions 47a protrudes downward in the Z direction from an end portion on the left side in the Y direction (the right side in the plane of FIG. 4) of the fourth plate-like protruding portion 46, and the other fourth partition 47b protrudes downward in the Z direction from an end portion on the right side in the Y direction (the left side in the plane of FIG. 4) of the fourth plate-like protruding portion 46.

[0029] With the reinforcing frame 25 fitted and fixed to the box body 10, the opening on the front side in the X direction of the second recess 23 (see FIG. 3) substantially faces the opening on the rear side in the X direction of the fourth recess 43 with a gap in the X direction. The reinforcing frame 25 has a plurality of elongated recesses 48 at the rear end in the X direction and the upper end in the Z direction. Since the reinforcing frame 25 has a structure that is substantially symmetrical with respect to the plane Q, the structure of the plurality of recesses 48 is substantially the same as the structure of the plurality of fourth recesses 43.

[0030] In addition, a case has been described in which a plurality of third recesses 33 share a common third plate-shaped protruding portion 37, and the middle partition portion 38c partitions adjacent third recesses 33. In addition, a case has been described in which a plurality of fourth recesses 43 have mutually different fourth plate-shaped protruding portions 46, and a pair of fourth partition portions 47a, 47b define only a part of the inner surface of one fourth recess 43. However, the third recess located on the rear side in the X direction and on both sides in the Y direction of the vertically placed delivery box 1 may have a structure similar to the above-mentioned fourth recess 43, and conversely, the fourth recess located on the rear side in the X direction and on the lower side in the Z direction of the vertically placed delivery box 1 may have a structure similar to the above-mentioned third recess 33.

[0031] The reinforcing frame 25 has an inner frame portion 52 that defines an opening 51. The inner frame portion 52 has a shape that is substantially rectangular in plan view from the rear side in the X direction, and protrudes in the X direction in a direction substantially perpendicular to a plane including the Y direction and the Z direction. The inner frame portion 52 has a pair of plate-like portions 52a on both sides in the Y direction that spread substantially parallel to a plane including the X direction and the Z direction and extend in the Z direction. In addition, only the first plate-like portion 52b located on the left side (the right side in the paper surface of FIG. 4) of the pair of plate-like portions 52a has a through hole 31 that is substantially rectangular in plan view when viewed from the Y direction.

[0032] As will be briefly explained later, a latch bolt of locking device 50 fits into this through hole 31 when delivery box 1 is locked, and the latch bolt retracts from through hole 31 when delivery box 1 is locked. Reinforcing frame 25 has hinge mounting portion 53 with screw holes 39 on the rear side in the X direction, the right side in the Y direction (the left side on the paper surface of FIG. 4), and both sides in the Z direction. This hinge mounting portion 53 is used when attaching door 40 to reinforcing frame 25. The attachment of door 40 to reinforcing frame 25 will be briefly explained later.

[0033] Next, the structures of the first and second reinforcing plates 60, 70 will be described. In this embodiment, the first reinforcing plate 60 is the same as the second reinforcing plate 70. Below, the structure of the first reinforcing plate 60 will be described, and a description of the structure of the second reinforcing plate 70 will be omitted. Note that, like the box body 10, the first reinforcing plate 60 (second reinforcing plate 70) is also an integrally molded resin product, and is formed from a resin such as polypropylene (PP) or acrylonitrile styrene acrylate (ASA).

[0034] FIG. 5 is a perspective view of the first reinforcing plate 60 as viewed from the front side, and FIG. 6 is a perspective view of the first reinforcing plate 60 as viewed from the back side. As shown in FIG. 5, the first reinforcing plate 60 is a plate member having a substantially rectangular shape in a plan view as viewed from the outside of the front side, and has a tapered shape from the front side to the rear side. As shown in FIGS. 5 and 6, the first reinforcing plate 60 has a front fitting portion 61 protruding forward at the front end, and a rear fitting portion 62 protruding rearward at the rear end. The first reinforcing plate 60 has screw holes 63, 64 arranged, for example, in two rows and two columns on the front and rear sides in the longitudinal direction. As will be described later, these screw holes 63, 64 may be used when fixing the first reinforcing plate 60 to the base 80 via the bottom plate portion 15. The first reinforcing plate 60 has a pair of protrusions 67 protruding outward in the width direction on the front side. The role of these protrusions 67 will be described later.

[0035] As shown in Fig. 6, the first reinforcing plate 60 has a case portion 68 that defines an internal space that opens only to the back side in the thickness direction, and reinforcing rib portions 65 that are provided in the internal space and are arranged in a diagonal lattice pattern. The reinforcing rib portions 65 protrude in the thickness direction of the first reinforcing plate 60 from a back surface 69a of a lid portion 69 in the case portion 68. The first reinforcing plate 60 has boss portions 77 that are arranged, for example, in two rows and two columns on each of the front and rear sides in the longitudinal direction. Each boss portion 77 protrudes in the thickness direction of the first reinforcing plate 60 from the back surface 69a of the lid portion 69. The screw hole 63 includes a portion provided in the boss portion 77.

[0036] FIG. 7 is a perspective view of the vertically placed delivery box 1 when viewed from diagonally rear and above, and is a perspective view that allows the internal structure to be seen. FIG. 8 is an enlarged perspective view of the rear fitting portion of the first reinforcing plate 60 in FIG. 7, and FIG. 9 is an enlarged perspective view of the front fitting portion of the first reinforcing plate 60 in FIG. 7. Note that the internal structure of the delivery box 1 cannot actually be seen, so it needs to be shown by dotted lines, but for ease of understanding, the internal structure is shown by solid lines in FIGS. 7 to 9. Referring again to FIGS. 3 to 5, the rear fitting portion 62 (see FIG. 5) of the first reinforcing plate 60 has a shape corresponding to the first recess 16 (see FIG. 3) and also has a shape corresponding to the second recess 23. Furthermore, the front fitting portion 61 (see FIG. 5) of the first reinforcing plate 60 has a shape corresponding to the third recess 33 (see FIG. 4) of the reinforcing frame 25 and also has a shape corresponding to the fourth recess 43.

[0037] 7 and 8, the rear fitting portions 62 of the first reinforcing plate 60 are press-fitted and fixed into the first recesses 16 located at the center in the Z direction of the box body 10 on both sides in the Y direction. Also, as shown in FIG. 7, the rear fitting portions 62 of the two second reinforcing plates 70 are press-fitted and fixed into the second recesses 23 located at both ends in the Y direction of the box body 10. Next, the front fitting portions 61 of the first and second reinforcing plates 60 are fitted and fixed. For more details, referring to FIG. 7 and FIG. 9, the reinforcing frame 25 is press-fitted and fixed into the opening edge portion 6a (see FIG. 2) of the box body 10, and at the same time, the third recess 33 of the reinforcing frame 25 is press-fitted and fixed into the front fitting portion 61 of the first reinforcing plate 60. 7, substantially simultaneously with the fitting and fixing of the front fitting portion 61 of the first reinforcing plate 60, the fourth recess 43 of the reinforcing frame 25 is fitted and fixed by press fitting into the front fitting portion 61 of the second reinforcing plate 70. In this manner, the first reinforcing plate 60, the second reinforcing plate 70, the box body 10, and the reinforcing frame 25 are assembled together.

[0038] As shown in FIG. 9, when the rear fitting portion 62 of the first reinforcing plate 60 is fitted into the first recess 16, the upper and lower ends of the first reinforcing plate 60 are clamped by a pair of first reinforcing plate guides 21 (see FIG. 3), and the first reinforcing plate 60 is positioned with high precision in the Z direction. When the rear fitting portion 62 is fitted into the first recess 16, a pair of protrusions 67 of the first reinforcing plate 60 engage with recesses 21a provided on the front side and outside of the first reinforcing plate guide 21, and the first reinforcing plate 60 is positioned with high precision in the X direction. Although not described in detail, the second reinforcing plate guide 28 (see FIG. 3) has the same structure as the first reinforcing plate guide 21 and has recesses on the front side and lower side. The second reinforcing plate guide 28 is used to position the second reinforcing plate 70 with high precision in the X direction and to position it with high precision in the Y direction.

[0039] 7, the top surface 19b of the top plate portion 19 of the box body 10 inclines toward the bottom plate portion 15 in the Z direction toward the rear in the X direction, and the bottom surface (outer surface) 15b of the bottom plate portion 15 of the box body 10 inclines toward the top plate portion 19 in the Z direction toward the rear in the X direction. In addition, the outer surface 12b of the first side plate portion 12 of the box body 10 inclines toward the second side plate portion 13 in the width direction toward the rear in the X direction, and the outer surface 13b of the second side plate portion 13 of the box body 10 inclines toward the first side plate portion 12 in the width direction toward the rear in the X direction.

[0040] Because top surface 19b of top plate portion 19 is inclined toward bottom plate portion 15 in the Z direction toward the rear in the X direction, even if delivery box 1 is placed in a location exposed to rainwater, rainwater that falls on top surface 19b can flow rearward along top surface 19b. This prevents rainwater from entering delivery box 1 and also prevents rainwater from remaining on top surface 19b and causing corrosion of the top surface.

[0041] The top surface 19b and the bottom surface 15b are inclined toward the center in the Z direction toward the rear in the X direction, and the two side surfaces (outer surfaces) 12b, 13b are also inclined toward the center in the Y direction toward the rear in the X direction, so that the internal chamber (luggage chamber) 2 tapers. However, since the thickness of the first and second reinforcing plates 60, 70 gradually decreases from the front to the rear as described above, the inclination of the inner surface of the internal chamber 2 can be countered by the inclination of the first and second reinforcing plates 60, 70, and the inner surfaces of the first and second reinforcing plates 60, 70 can define a substantially rectangular parallelepiped space, forming the internal chamber 2 in which contractors and the like can easily store luggage.

[0042] Bottom surface 15b is inclined toward the center in the Z direction toward the rear in the X direction. Therefore, in order to stably place delivery box 1 on the placement surface, base 80 is attached to bottom surface 15b of bottom plate portion 15 of box body 10. Next, the structure of base 80 and its fixing structure will be described. FIG. 10 is a perspective view of base 80 as viewed from below, and FIG. 11 is a perspective view of base 80 as viewed from above (mounting side). Like box body 10, base 80 is also an integrally molded resin product, and is formed from resin such as polypropylene (PP) or acrylonitrile styrene acrylate (ASA).

[0043] As shown in FIG. 10, the base 80 is a plate member having a substantially rectangular shape in plan view when viewed from the outside of the front side, and is tapered from the rear side to the front side in the X direction. The base 80 has two screw holes 81 arranged in a row in the X direction, for example, at each of the four corners of the substantially rectangular bottom surface. As shown in FIG. 11, the base 80 has a case portion 88 that defines an internal space that opens only to the upper side in the thickness direction, and a reinforcing rib portion 85 that is provided in the internal space and stretched in a diagonal lattice pattern. The depth of the internal space becomes shallower from the rear side to the front side in the X direction. The reinforcing rib portion 85 protrudes from an upper surface 89a of a bottom portion 89 of the case portion 88 to the upper side in the thickness direction of the base 80. The base 80 has two boss portions 83 arranged in a row in the X direction, for example, at each of the four corners of the internal space that has a substantially rectangular opening on the upper side. Each boss portion 83 protrudes upward in the thickness direction from an upper surface 89a of a bottom portion 89 of a case portion 88. The screw hole 81 includes a portion provided in the boss portion 83.

[0044] As shown in FIG. 1, the opening area of ​​the case portion 88 of the base 80 is slightly smaller than the bottom surface 15b of the bottom plate portion 15 of the delivery box 1. The base 80 is arranged so that the opening of the case portion 88 is completely closed by the portion other than the edge of the bottom surface 15b of the bottom plate portion 15, with the longitudinal direction of the base 80 approximately aligned with the X direction and the width direction of the base 80 approximately aligned with the Y direction. After that, for example, four screws are fastened into the four screw holes 81a on the four corner sides or the four screw holes 81b on the side farther from the four corners, and then the screws are sequentially fastened into the through holes provided in the bottom plate portion 15 of the box body 10 and into the screw holes of the second reinforcing plate 70 (see FIG. 7) attached to the box body 10, thereby fixing the base 80 to the box body 10 and the second reinforcing plate 70.

[0045] Alternatively, without providing through holes in the bottom plate 15 of the box body 10, adhesive is poured from the outside into the four screw holes 81a on the four corner sides or the four screw holes 81b on the side farther from the four corners to bond the boss 83 (see FIG. 11) to the bottom plate 15 of the box body 10 at the places where the boss 83 abuts. In this manner, the base 80 can also be fixed to the box body 10.

[0046] Fig. 12 is a side view of the delivery box 1 as viewed from the outside in the Y direction, and shows the internal structure in solid lines. As shown in Fig. 12, the bottom plate portion 15 of the box body 10 is inclined upward toward the rear. The base 80 is tapered from the rear to the front. Therefore, after the base 80 is fixed to the underside of the bottom plate portion 15 of the box body 10, the bottom surface 99 of the delivery box 1 can be made into a flat surface that is approximately perpendicular to the Z direction.

[0047] Next, the fixing structure of the door 40 and the fixing structure of the locking device 50 will be briefly described. The door 40, like the box body 10, is an integrally molded resin product, and is formed from resin such as polypropylene (PP) or acrylonitrile styrene acrylate (ASA). Referring again to FIG. 2, the door 40 has a locking device exposure window 41 on the left side in the Y direction, which has a generally rectangular elongated shape and extends in the Z direction. The door 40 also has hinge mounting recesses 42 on both ends in the Z direction at the right end in the Y direction. The hinge mounting recess 42 is provided with a bottomed cylindrical hole 91 extending in the Z direction.

[0048] In contrast, the hinges 5a and 5b have a round bar portion 90 and a flat plate portion 92. The hinge 5a is attached to the hinge attachment recess 42 on the upper side of the door 40, and the hinge 5b is attached to the hinge attachment recess 42 on the lower side of the door 40. With the round bar portions 90 of the hinges 5a and 5b inserted into the bottomed cylindrical holes 91 of the hinge attachment recesses 42, the flat plate portions 92 are fastened and fixed to the screw holes 39 (see FIG. 4) of the reinforcing frame 25 using screws, thereby fixing the door 40 to the reinforcing frame 25 so as to be able to be opened and closed freely.

[0049] The locking device 50 is attached to the door 40 so that a portion of it is exposed to the front through the locking device exposure window 41. The locking device 50 may be configured with any known device that is used in a delivery box and can lock and unlock the door. For example, the locking device 50 may be configured with an electronic lock that allows the door 40 to be electrically locked and unlocked. Next, the locking and unlocking operations of the locking device 50 when it is an electronic lock will be briefly described without using figures.

[0050] In this case, inside the locking device 50, a power supply unit including a battery, a control device to which power is supplied from the power supply unit, an electric actuator including a solenoid or the like driven by the control device, and a locking mechanism are arranged. An operation signal generated by operating an operation unit consisting of a numeric keypad input unit or the like is input to the control device. The locking mechanism includes a latch bolt (a protruding part that can be advanced and retreated) (not shown) that can advance and retreat to the left in the Y direction, and a moving part that moves the latch bolt. The control device drives the electric actuator based on the operation signal to move the moving part, thereby causing the latch bolt to protrude outward in the Y direction from the locking device main body, or to retreat inward in the Y direction toward the locking device main body.

[0051] When the latch bolt is in a protruding state, it fits into the through hole 31 (see FIG. 4) of the reinforcing frame 25, and the door 40 is in a locked state. Conversely, when the latch bolt is in a retracted state, the latch bolt does not interfere with the through hole 31, and the door 40 is unlocked. For this reason, after a delivery person places a package in the internal chamber 2, the delivery person can close the door 40, enter a PIN number on the numeric keypad input unit, and then press the decision button provided on the numeric keypad input to lock the door 40. Also, the recipient of the package can unlock the door 40 by entering a PIN number on the numeric keypad input unit and then pressing the decision button.

[0052] FIG. 13 is a plan view of the delivery box 1 before the base 80 is attached, as viewed from below in the Z direction, and shows only the second reinforcing plate 70 as an internal structure in solid lines. As shown in FIG. 13, in the delivery box 1, when the door 40 is closed, the front plate portion 47 of the door 40 is offset rearward in the X direction with respect to the shaft 76 that rotates the door 40, and is located rearward in the X direction from the shaft 76. This allows the door 40 to be rotated 90° or more from the closed position, making it easier to store luggage in the internal chamber 2 and to remove luggage from the internal chamber 2. In addition, since the front plate portion 47 is located rearward, the reinforcing frame 25 can be used as a canopy. Therefore, it is possible to prevent the front plate portion 47 from being exposed to direct sunlight or rainwater, and to prevent deterioration of the door 40. If this offset is not adopted, the door will interfere with the side plate portion and the door will only open about 90° from the closed position.

[0053] Next, the high degree of freedom of arrangement and excellent mass productivity of the delivery box 1 of the present disclosure will be described. FIG. 14(a) is a perspective view of the door 40, FIG. 14(b) is a perspective view of the reinforcing frame 25, and FIG. 14(c) is a perspective view of the box body 10. As shown in FIG. 14(a), the door 40 is approximately plane-symmetrical with respect to a plane P that passes through the center in the Z direction and includes the X direction and the Y direction. As will be described again, as shown in FIG. 14(b), the reinforcing frame 25 is approximately plane-symmetrical with respect to a plane Q that passes through the center in the Z direction and includes the X direction and the Y direction. As shown in FIG. 14(c), the box body 10 is approximately plane-symmetrical with respect to a first plane R that passes through the midpoint of the Y direction and includes the X direction and the Z direction, and is also approximately plane-symmetrical with respect to a second plane S that passes through the midpoint of the Z direction and includes the X direction and the Y direction.

[0054] Therefore, as shown in FIG. 15, a right-opening delivery box 1 can be constructed by attaching the door 40 to the right side of the box body 10 in the Y direction. Also, since the door 40, the reinforcing frame 25, and the box body 10 are symmetrical with respect to the planes P, Q, R, and S, as shown in FIG. 16, the door 40 and the reinforcing frame 25 can be attached to the left side of the box body 10 in the Y direction upside down with respect to the state shown in FIG. 15, and a left-opening delivery box 101 can be produced simply by replacing the locking device 50 with a locking device 150 in which the latch bolt advances and retreats on the right side in the Y direction. Therefore, the door 40, the reinforcing frame 25, and the box body 10 can be made common between the right-opening delivery box 1 and the left-opening delivery box 101, and therefore it is easy to mass-produce the delivery box 1, 101 which has a high degree of freedom in the installation of the door 40 and is highly versatile.

[0055] 7 again, in the vertically oriented delivery box 1, the top surface 19b of the top plate portion 19 of the box body 10 inclines toward the bottom plate portion 15 in the Z direction as it moves toward the rear in the X direction, and the bottom surface 15b of the bottom plate portion 15 of the box body 10 inclines toward the top plate portion 19 in the Z direction as it moves toward the rear in the X direction. In addition, the outer surface 12b of the first side plate portion 12 of the box body 10 inclines toward the second side plate portion 13 in the width direction as it moves toward the rear in the X direction, and the outer surface 13b of the second side plate portion 13 of the box body 10 inclines toward the first side plate portion 12 in the width direction as it moves toward the rear in the X direction.

[0056] 17, a horizontally oriented delivery box 201 can be easily realized simply by changing the placement surface of the box body 10 and further replacing the locking device 50 with a locking device 250 with a horizontally oriented numeric keypad. Note that in the vertically oriented delivery box 1, the outer surface 12b of the first side panel portion 12 is inclined toward the second side panel portion 13 in the width direction as it approaches the rear in the X direction, so that the top surface 12b of the top panel portion 12 of the horizontally oriented delivery box 201 is inclined downward as it approaches the rear in the X direction.

[0057] Therefore, even if the delivery box is delivery box 201 placed horizontally, rainwater that falls on top surface 12b can flow rearward along top surface 12b. This prevents rainwater from entering delivery box 1, and also prevents rainwater from remaining on top surface 12b and causing corrosion of the top surface. Delivery box 201 can share door 40, reinforcing frame 25, and box body 10 with delivery box 1, 101, so delivery boxes 1, 101, 201, which have a high degree of freedom in arrangement and are highly versatile, can be mass-produced.

[0058] 18, in horizontally oriented delivery box 201, door 40 opens in the vertical direction. In horizontally oriented delivery box 201, reinforcing plate 60 that was arranged on the side as first reinforcing plate 60 in vertically oriented delivery box 1 is arranged on the lower side as a lower second reinforcing plate, and upper surface 60a of reinforcing plate 60 forms the lower surface of internal chamber 2 of delivery box 201.

[0059] If a free-stop hinge is used in the horizontally placed delivery box 201, the door 40 can be stopped at any position by static friction, which increases convenience. It is not necessary to use a free-stop hinge, and the door 40 may be held open by hand or by using a stop bar. The door 40 may also be rotated upward by 90° or more and allowed to fall backward to prevent the door 40 from closing due to gravity.

[0060] Fig. 19 is a perspective view of horizontally oriented delivery box 201 as viewed from the lower front. As shown in Fig. 7, in vertically oriented delivery box 1, outer surface 13b of second side plate portion 13 is inclined toward first side plate portion 12 in the width direction as it approaches the rear in the X direction, so bottom surface 13b of bottom plate portion 13 of horizontally oriented delivery box 201 is inclined upward as it approaches the rear in the X direction. Therefore, it is necessary to attach base 80 to bottom surface 13b.

[0061] 7, in this embodiment, in box body 10, the inclination angle of the outer surface of first side plate portion 12 with respect to the X direction, the inclination angle of the outer surface of second side plate portion 13 with respect to the X direction, the inclination angle of bottom surface 15b of bottom plate portion 15 with respect to the X direction, and the inclination angle of top surface 19b of top plate portion 19 with respect to the X direction are all the same. Therefore, the same base 80 can be used when the delivery box is vertically oriented delivery box 1,101 and when it is horizontally oriented delivery box 201, which increases the versatility of base 80 and makes it easier to mass-produce base 80.

[0062] In addition, when the delivery box is a vertically oriented delivery box 1,101, if the Y-direction dimension at the rear end of the outer surface of the first side panel portion 12 is more than twice the Y-direction dimension at the rear end of the top surface 19b, a base 80 with a large mounting surface area can be used, which is preferable as it makes it easier to stably install the box body 10. In addition, in the delivery box 201, as shown in Fig. 19, two bases 80 are fixed to the box body 10 in a state where they are adjacent (in contact) in the Z direction. However, in either a vertically oriented or horizontally oriented delivery box, two or more bases may be fixed to the box body in the same orientation with a gap between them.

[0063] Finally, a case where two delivery boxes are arranged in two tiers will be described. FIG. 20 is a diagram for explaining a case where the same delivery boxes 1 arranged vertically are arranged in two tiers, and FIG. 21 is a diagram for explaining a case where the same delivery boxes 201 arranged horizontally are arranged in two tiers. As shown in FIG. 21 and FIG. 22, in either case of vertical or horizontal arrangement, when viewed from above, the first or second pedestal 80 and the first or second pedestal 80 (hereinafter, this pedestal is referred to as the upper pedestal 80a) are arranged upside down with the first or second pedestal 80 installed on the lower side so as to overlap with the first or second pedestal 80 installed on the lower side, and the upper pedestal 80a is fastened and fixed to the pedestal 80 of the upper delivery box 1,210 using the screw hole 81 (see FIG. 10).

[0064] Here, as the screw holes used for this fixing, four screw holes 81a (see FIG. 10) close to each corner can be used, or four screw holes 81b (see FIG. 10) away from each corner can be used. In addition, the upper base 80a and the upper surface of the lower delivery box 1,210 may be fixed with an adhesive. Alternatively, a reinforcing plate may be fixed to a fitting portion (see recess 48 in FIG. 4) on the upper side of the internal chamber 2 of the lower delivery box 1,210, and the reinforcing plate, the bottom plate portion of the lower delivery box 1,210, the upper base 80a, the bottom plate portion of the upper delivery box 1,210, and the reinforcing plate installed on the lower side of the internal chamber 2 of the upper delivery box 1,210 may be screwed with the same screw member (for example, a bolt).

[0065] In these embodiments, the upper base 80a disposed between the two delivery boxes 1,210 can be the same base as the base 80 installed below the delivery boxes 1,210. Therefore, whether the delivery boxes 1,201 are placed vertically or horizontally, the delivery boxes 1,201 can be easily stacked, and multiple-tiered delivery boxes can be easily manufactured with excellent mass productivity. As shown in FIG. 2, the delivery box 1 includes a cover 8. As shown in FIG. 1 and FIG. 17, the cover 8 is attached to the handle 55 of the door 40.

[0066] Next, the essential configuration and its working effects will be described for the delivery box 1, 101, 201 of the present disclosure. Note that, below, the essential configuration and its working effects will be described using the vertical delivery box 1, 101 as an example, but even in the case of the horizontal delivery box 201, the essential configuration and its working effects are the same as those of the vertical delivery box 1, 101.

[0067] The delivery box 1,101 includes a box body 10 made of a resin integrally molded product that defines an internal chamber 2 that opens at the front side in the X direction, a reinforcing frame 25 that is fitted and attached to an opening edge portion 6a at a front end portion 6 of the box body 10, a door 40 that is attached to the reinforcing frame 25 via hinges 5a, 5b, and a locking device 50 that is attached to the door 40 and selectively enables locking or unlocking of the door 40. The box body 10 also has a first recess 16 (side fitting and fixing portion) for fitting and fixing a first reinforcing plate 60 that extends along the inner surfaces 12a, 13a of the side plate portions 12, 13 of the box body 10, and a second recess 23 (bottom fitting and fixing portion) for fitting and fixing a second reinforcing plate 70 that extends along the inner surface of the bottom plate portion 15 of the box body 10. Furthermore, the delivery box 1,101 includes at least one of a first reinforcing plate 60 fixed to the first recess 16 and a second reinforcing plate 70 fixed to the second recess 23. In the present embodiment, the delivery box 1,101 includes both the first reinforcing plate 60 fixed to the first recess 16 and the second reinforcing plate 70 fixed to the second recess 23. However, the delivery box 1,101 may include only one of the first reinforcing plate 60 and the second reinforcing plate 70.

[0068] The delivery box 1,101 employs a box body 10 made of a resin integrally molded product that defines an internal chamber 2 that opens at the front side in the X direction, which allows for good assembly and excellent mass production. In addition, the delivery box 1,101 includes at least one of a first reinforcing plate 60 extending along the inner surfaces 12a, 13a of the side plate portions 12, 13 of the box body 10 and a second reinforcing plate 70 extending along the inner surface 15a of the bottom plate portion 15 of the box body 10, which allows for high rigidity. In addition, the box body 10 has the first recess 16 for fitting and fixing the first reinforcing plate 60 extending along the inner surfaces 12a, 13a of the side plate portions 12, 13 of the box body 10, and the second recess 23 for fitting and fixing the second reinforcing plate 70 extending along the inner surface 15a of the bottom plate portion 15 of the box body 10, so that the delivery box 1, 101, 201 can be flexibly arranged both vertically and horizontally. For example, the upper surface of the second reinforcing plate 60 or 70 can form the lower surface of the internal chamber 2 whether the delivery box 1, 101, 201 is arranged vertically or horizontally. Therefore, the degree of freedom in arranging the delivery box 1, 101, 201 can be increased.

[0069] In addition, when the delivery box 1,101 is placed upright, the first recess 16 constitutes the side fitting and fixing portion, and the second recess 23 constitutes the bottom fitting and fixing portion, but when the delivery box 201 is placed horizontally, the second recess 23 constitutes the side fitting and fixing portion, and the first recess 16 constitutes the bottom fitting and fixing portion.

[0070] Next, configurations that are preferable to adopt in the delivery box 1, 101, 201 of the present disclosure and their working effects will be described. These configurations do not necessarily have to be adopted. Note that the configurations that are preferable to adopt and their working effects will be described using the vertical delivery box 1, 101 as an example, but even in the case of the horizontal delivery box 201, the configurations that are preferable to adopt and their working effects are the same as those of the vertical delivery box 1, 101.

[0071] In the delivery box 1, 101, when the door 40 is closed, the front panel portion 47 of the door 40 may be offset rearward in the X direction with respect to the axis 76 about which the door 40 rotates.

[0072] According to this configuration, the door 40 can be rotated by 90° or more from the closed position, making it easier to put luggage into the internal chamber 2 and easier to remove luggage from the internal chamber 2.

[0073] Furthermore, the top surface 19b of the top plate portion 19 of the box body 10 may have a first inclined portion that inclines toward the bottom plate portion 15 in the Z direction toward the rear side in the X direction. Furthermore, the outer surface 12b of the first side plate portion 12 of the box body 10 may have a second inclined portion that inclines toward the second side plate portion 13 in the width direction toward the rear side in the X direction. Here, in this embodiment, the first inclined portion is configured over the entire surface of the top surface 19b, and the second inclined portion is configured over the entire surface of the outer surface 12b of the first side plate portion 12. However, the first inclined portion may be configured over a part of the top surface 19b, and the second inclined portion may be configured over a part of the outer surface 12b of the first side plate portion 12.

[0074] According to this configuration, whether the delivery box 1, 101, 201 is used in a vertical or horizontal orientation, by arranging the top surface to include the first inclined portion or the second inclined portion, rainwater can be made to flow smoothly along the top surface to the outside of the delivery box 1, 101, 201. This makes it possible to prevent rainwater from entering the delivery box 1, 101, 201, and also to prevent rainwater from remaining on the top surface of the delivery box 1, 101, 201 and causing top surface corrosion.

[0075] In addition, in the delivery box 1, 101, 201, the bottom surface 15b of the bottom plate portion 15 of the box body 10 may have a third inclined portion inclined toward the top plate portion 19 in the Z direction as it approaches the rear side in the X direction, and the outer surface 13b of the second side plate portion 13 of the box body 10 may have a fourth inclined portion inclined toward the first side plate portion 12 in the width direction as it approaches the rear side in the X direction. The third inclination angle of the third inclined portion with respect to the X direction may be approximately the same as the fourth inclination angle of the fourth inclined portion with respect to the X direction. Here, in the embodiment, the third inclined portion is configured over the entire surface of the bottom surface 15b, and the fourth inclined portion is configured over the entire surface of the outer surface 13b of the second side plate portion 13. However, the third inclined portion may be configured over a part of the bottom surface 15b, and the fourth inclined portion may be configured over a part of the outer surface 13b of the second side plate portion 13.

[0076] According to this configuration, the same base 80 can be used whether the delivery box 1, 101 is used vertically or whether the delivery box 201 is used vertically. This increases the versatility of the base 80. Note that, as in this embodiment, if the first inclination angle of the first inclined portion with respect to the X direction, the second inclination angle of the second inclined portion with respect to the X direction, the third inclination angle of the third inclined portion with respect to the X direction, and the four inclination angles of the fourth inclined portion with respect to the X direction are all substantially the same, not only can the versatility of the base 80 be increased, but also a delivery box 1, 101, 201 that is symmetrical and aesthetically pleasing can be realized.

[0077] Furthermore, the top surface 19b of the top plate portion 19 of the box body 10 may have a first inclined portion that inclines toward the bottom plate portion 15 in the Z direction as it approaches the rear side in the X direction. As shown in Fig. 20, the box may further include an upper pedestal 80a that is arranged in contact with the top surface 19b and has an upper surface that extends in a direction approximately perpendicular to the Z direction.

[0078] According to this configuration, as shown in Figs. 20 and 21, delivery boxes 1, 101, 201 can be stacked in two or more tiers depending on preference.

[0079] The present disclosure is not limited to the above-described embodiment and its modified examples, and various improvements and modifications are possible within the scope of the claims of the present application and their equivalents.

[0080] For example, in the above embodiment, the first reinforcing plate 60 and the second reinforcing plate 70 are identical, and therefore the reinforcing plates can be mass-produced. However, the first reinforcing plate may be different from the second reinforcing plate.

[0081] Also, the case where the first tilt angle with respect to the X direction, the second tilt angle with respect to the X direction, the third tilt angle with respect to the X direction, and the fourth tilt angle with respect to the X direction are substantially the same has been described. However, the first tilt angle, the second tilt angle, the third tilt angle, and the fourth tilt angle may be two or more different tilt angles.

[0082] In addition, the delivery box of the present disclosure may have an inclined portion only on the top surface, and the bottom surface and the pair of outer surfaces of the pair of side panels may not have an inclined portion. Also, only the top surface and the outer surface of one of the side panels may have an inclined portion.
