Description

This disclosure relates to delivery boxes.

A conventional delivery box is described in Patent Document 1. This delivery box has an opening on the front and is equipped with a resin main body with top and bottom, left and right sides, and a back molded as a single unit, an opening door that is connected to the main body and allows the opening to be opened and closed freely, and a locking mechanism provided on the opening door. Since the top and bottom, left and right sides, and a back are molded as a single unit, this delivery box is easy to assemble and mass-produce.

JP 2020-99454 A

If a resin body is used in which the top, bottom, left and right sides, and back are molded as a single unit, the rigidity of the delivery box may be reduced, making it more susceptible to damage. Furthermore, in recent years, the variety of products being delivered has increased, and the packages being delivered come in a wide variety of shapes, so there are cases where it is preferable for the delivery box to be placed vertically and cases where it is preferable for it to be placed horizontally. However, the delivery box has the problem that it cannot be flexibly positioned depending on the purpose.

The objective of this disclosure is to provide a delivery box that has an integrally molded resin body, making it easy to assemble, and that is easy to increase rigidity and flexibility in placement.

In order to solve the above problems, the delivery box according to the present disclosure comprises a box body made of a resin integrally molded product that defines an internal chamber that opens at the front in the depth direction, a reinforcing frame that is fitted and attached to the opening edge 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 plate 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 plate of the box body, and 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.

The above-mentioned side plate portions and bottom plate portions refer to the side plate portions and bottom plate portions 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.

The delivery box according to the present disclosure employs 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, and therefore has good assembly properties and excellent mass production properties. In addition, the delivery box has at least one of a first reinforcing plate that extends along the inner surface of the side plate of the box body and a second reinforcing plate that extends along the inner surface of the bottom plate of the box body, so that the rigidity can be increased. In addition, the box body has a side-side fitting and fixing portion for fitting and fixing the first reinforcing plate that extends along the inner surface of the side plate of the box body, and a bottom-side fitting and fixing portion for fitting and fixing the second reinforcing plate that extends along the inner surface of the bottom plate of the box body, so that the delivery box can be flexibly placed either vertically or horizontally. For example, whether the delivery box is placed vertically or horizontally, the lower surface of the internal chamber can be formed by the upper surface of the second reinforcing plate. Therefore, the degree of freedom in the placement of the delivery box can be increased.

Fig. 1 is a perspective view showing a delivery box 1 according to one embodiment of the present disclosure placed vertically, and Fig. 2 is an exploded perspective view of the main components of the delivery box 1. As shown in Fig. 1, the delivery box 1 has a generally rectangular parallelepiped shape. The delivery box 1 is for use in, for example, a detached house, and can receive parcels (not shown) that are delivered to the home. The delivery box 1 is used by parcel delivery personnel to leave parcels when the resident is not at home, etc. The delivery box 1 is placed, for example, outside the detached house near the front door.

2, the delivery box 1 includes a box body 10, a reinforcing frame 25 attached to the box body 10, a door 40 attached to the reinforcing frame 25 via hinges 5a, 5b, a locking device 50 attached to the door 40 to selectively lock or unlock the door 40, a pair of first reinforcing plates 60 fitted and fixed to the inside of the side plate portions 12, 13 of the box body 10, a pair of second reinforcing plates 70 fitted and fixed to the bottom plate portion 15 of the box body 10, and a base 80 screwed to the bottom plate portion 15 of the box body 10. The mounting structure of each component will be described below. First, in order to explain the mounting structure of the first and second reinforcing plates 60, 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, 70 will be described.

The box body 10 has a generally 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 generally rectangular parallelepiped box shape capable of accommodating luggage (not shown). The box body 10 is a one-piece resin molded product, and is formed from resin such as polypropylene (PP) or acrylonitrile styrene acrylate (ASA). Figure 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 generally plane-symmetrical with respect to a first plane R (see Figure 14) that passes through the midpoint of the Y direction and includes the X direction and the Z direction, and also has a structure that is generally plane-symmetrical with respect to a second plane S (see Figure 14) that passes through the midpoint of the Z direction and includes the X direction and the Y direction.

In the following, the structure located on the left side of the first plane R when viewed from the front side will be described first. Since the box body 10 has a structure that is approximately flush with the first plane R, the structure located on the right side of the first plane R when viewed from the front side will not be described. 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, multiple 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 protrusion 17 in the shape of an elongated flat plate that protrudes from the inner surface 14a of the rear plate portion 14 to the front side in the X direction. The first plate-like protrusion 17 is approximately parallel to the inner surface 12a of the side plate portion 12 and extends in the Z direction.

The box body 10 further has a plurality of plate-shaped first partitions 18. Each first partition 18 has a flat plate shape and protrudes forward in the X direction from the inner surface 14a of the rear plate 14. Each first partition 18 is approximately parallel to a plane that is approximately perpendicular to the first plate-shaped protrusion 17 and is approximately parallel to the inner surface 19a of the top plate 19. The plurality of first partitions 18 include an upper partition 18a that connects the upper end of the first plate-shaped protrusion 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 protrusion 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 protrusion portion 17, and two partition portions 18 adjacent to each other in the Z direction.

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 that protrude 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 a distance in the X direction and are provided at approximately the same Z direction position as the intermediate partition 18c. The first reinforcing plate guides 21 have a recess 21a that penetrates 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.

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-shaped protrusion 26, and a pair of second partitions 27a, 27b. In detail, the second plate-shaped protrusion 26 has an elongated flat plate shape and protrudes from the inner surface 14a of the rear plate portion 14 to the front side in the X direction approximately parallel to the inner surface 15a of the bottom plate portion 15 and extends in the Y direction. In addition, the pair of second partitions 27a, 27b are arranged at intervals in the Y direction. Each partition 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 approximately parallel to the inner surface 12a of the side plate portion 12. One second partition 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 27b connects the inner surface 12a to the right end of the second plate-shaped protrusion 26 in the Y direction.

The box body 10 further has a plurality of plate-shaped second reinforcing plate guides 28. The second reinforcing plate guides 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 guides 28 face the second partitions 27a, 27b at a distance in the X direction and are provided at approximately the same Y direction position as the second partitions 27a, 27b.

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

The above description concerns a case where multiple first recesses 16 share a common first plate-shaped protrusion 17, and the intermediate partition 18c partitions adjacent first recesses 16. The above description also concerns a case where a portion of each of multiple second recesses 23 is defined by a different second plate-shaped protrusion 26, and a pair of second partitions 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.

Next, the structure of the reinforcing frame 25 will be described. Like the box body 10, the reinforcing frame 25 is an integrally molded resin product, and is formed from resin such as polypropylene (PP) or acrylonitrile styrene acrylate (ASA). Referring to FIG. 2, the reinforcing frame 25 is press-fitted into 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 side of the internal chamber 2 (see FIG. 1). As shown in FIG. 4, the reinforcing frame 25 is approximately 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.

The reinforcing frame 25 has one or more elongated third recesses 33 extending in the Z direction at the rear side in the X direction and both ends in the Y direction, and in this embodiment, multiple third recesses 33 are arranged in three rows in the Z direction at 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 of the paper in Figure 4 will be described below, and the structure of the third recesses 33 on the left side in the Y direction of the paper in Figure 4 will be omitted.

The reinforcing frame 25 has a third plate-like protruding portion 37 that is an elongated flat plate that protrudes from the rear side in the X direction to the rear side in the X direction. The third plate-like protruding portion 37 is approximately parallel to a plane that includes the X direction and the Z direction, and extends in the Z direction. The reinforcing frame 25 further has a plurality of plate-like third partition portions 38. Each third partition portion 38 has a flat plate shape and protrudes outward in the Y direction from the outer surface of the third plate-like protruding portion 37 in the Y direction. Each third partition portion 38 is approximately perpendicular to the third plate-like protruding portion 37.

The third partitions 38 include an upper partition 38a protruding outward in the Y direction from the upper end of the third plate-shaped protrusion 37, a lower partition 38b protruding outward in the Y direction from the lower end of the third plate-shaped protrusion 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 protrusion 37, and two adjacent third partitions 38 spaced apart 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). When the reinforcing frame 25 is fitted and fixed to the box body 10, the opening on the front side in the X direction of the first recess 16 is approximately opposite the opening on the rear side in the X direction of the third recess 33, with a gap in the X direction.

The reinforcing frame 25 further has a number of elongated fourth recesses 43 extending in the Y direction at the rear end in the X direction and the lower end in the Z direction. The multiple fourth recesses 43 are arranged at intervals in the Y direction. Each fourth recess 43 is defined by the inner surface 25a of the reinforcing frame 25, a fourth plate-shaped protrusion 46, and a pair of fourth partitions 47a, 47b. Each fourth recess 43 opens to the rear side in the X direction and to the lower side in the Z direction.

The fourth plate-shaped protrusion 46 has a long, thin flat plate shape, protrudes forward in the X direction from the inner surface 25a of the reinforcing frame 25 approximately parallel to a plane including the X direction and the Y direction, and extends in the Y direction. In addition, a pair of fourth partitions 47a, 47b are arranged at intervals in the Y direction. Each of the fourth partitions 47a, 47b has a flat plate shape and extends approximately parallel to a plane including the X direction and the Z direction. One fourth partition 47a protrudes downward in the Z direction from the end of the fourth plate-shaped protrusion 46 on the left side in the Y direction (the right side in the paper of FIG. 4), and the other fourth partition 47b protrudes downward in the Z direction from the end of the fourth plate-shaped protrusion 46 on the right side in the Y direction (the left side in the paper of FIG. 4).

When the reinforcing frame 25 is fitted and fixed to the box body 10, the front opening in the X direction of the second recess 23 (see FIG. 3) is spaced apart in the X direction and generally faces the rear opening in the X direction of the fourth recess 43. The reinforcing frame 25 has multiple elongated recesses 48 at its rear end in the X direction and its upper end in the Z direction. Since the reinforcing frame 25 has a structure that is generally symmetrical with respect to the plane Q, the structure of the multiple recesses 48 is generally the same as the structure of the multiple fourth recesses 43.

The above description concerns a case where multiple third recesses 33 share a common third plate-shaped protrusion 37, and the intermediate partition 38c partitions adjacent third recesses 33. The above description also concerns a case where multiple fourth recesses 43 have different fourth plate-shaped protrusions 46, and a pair of fourth partitions 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.

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 approximately rectangular when viewed from the rear side in the X direction, and protrudes in the X direction in a direction that is approximately perpendicular to a plane that includes the Y direction and the Z direction. The inner frame portion 52 has a pair of plate-shaped portions 52a on both sides in the Y direction that extend approximately parallel to a plane that includes the X direction and the Z direction and extend in the Z direction. In addition, only the first plate-shaped portion 52b located on the left side of the pair of plate-shaped portions 52a (the right side in the paper surface of FIG. 4) is provided with a through hole 31 that is approximately rectangular in plan view when viewed from the Y direction.

As will be briefly explained later, the latch bolt of the locking device 50 fits into this through hole 31 when the delivery box 1 is locked, and the latch bolt retracts from the through hole 31 when the delivery box 1 is locked. The reinforcing frame 25 has a 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 the door 40 to the reinforcing frame 25. The attachment of the door 40 to the reinforcing frame 25 will be briefly explained later.

Next, the structure 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 the structure of the second reinforcing plate 70 will not be described. Note that the first reinforcing plate 60 (second reinforcing plate 70) is also an integrally molded resin product, like the box body 10, and is formed from a resin such as polypropylene (PP) or acrylonitrile styrene acrylate (ASA).

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 that is approximately rectangular in plan view when 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 that protrudes forward at the front end, and a rear fitting portion 62 that protrudes 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 screwing the plate to the base 80 via the bottom plate portion 15. The first reinforcing plate 60 has a pair of protrusions 67 on the front side that protrude outward in the width direction. The role of these protrusions 67 will be described later.

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 ribs 65 that are provided within the internal space and arranged in a diagonal lattice pattern. The reinforcing ribs 65 protrude in the thickness direction of the first reinforcing plate 60 from the back surface 69a of the lid portion 69 in the case portion 68. The first reinforcing plate 60 has bosses 77 arranged, for example, in two rows and two columns on each of the front and rear sides in the longitudinal direction. Each boss 77 protrudes in the thickness direction of the first reinforcing plate 60 from the back surface 69a of the lid portion 69. The screw holes 63 include portions provided in the bosses 77.

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

7 and 8, the rear fitting portion 62 of the first reinforcing plate 60 is press-fitted into the first recess 16 located in the center of the Z direction in the box body 10 on both sides in the Y direction to be fixed. Also, as shown in FIG. 7, the rear fitting portions 62 of the two second reinforcing plates 70 are press-fitted into the second recesses 23 located at both ends in the Y direction in the box body 10 to be fixed. 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 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 into the front fitting portion 61 of the first reinforcing plate 60 to be fixed. Also, as shown in FIG. 7, substantially simultaneously with the engagement and fixing of the front fitting portion 61 of the first reinforcing plate 60, the fourth recess 43 of the reinforcing frame 25 is press-fitted and fixed into the front fitting portion 61 of the second reinforcing plate 70. In this way, the first reinforcing plate 60, the second reinforcing plate 70, the box body 10, and the reinforcing frame 25 are assembled together.

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. Also, 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 the recesses 21a provided on the front and outer sides 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 and lower sides. 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.

As shown in FIG. 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 as it moves 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 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.

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

The top surface 19b and bottom surface 15b are inclined toward the center in the Z direction as they move 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 as they move toward the rear in the X direction, so the internal chamber (luggage chamber) 2 tapers. However, as described above, the thickness of the first and second reinforcing plates 60, 70 gradually decreases from the front to the rear, so 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 an approximately rectangular parallelepiped space, forming an internal chamber 2 that is easy for contractors and the like to store luggage in.

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

As shown in FIG. 10, the base 80 is a plate member that is approximately rectangular 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 approximately rectangular bottom surface. As shown in FIG. 11, the base 80 has a case part 88 that defines an internal space that opens only to the upper side in the thickness direction, and a reinforcing rib part 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 part 85 protrudes from the upper surface 89a of the bottom part 89 of the case part 88 to the upper side in the thickness direction of the base 80. The base 80 has two boss parts 83 arranged in a row in the X direction, for example, at each of the four corners of the internal space that has an approximately rectangular opening on the upper side. Each boss portion 83 protrudes upward in the thickness direction from the upper surface 89a of the bottom portion 89 of the case portion 88. The screw hole 81 includes a portion that is provided in the boss portion 83.

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 covered by the bottom surface 15b of the bottom plate portion 15 except for the edge portion, with the longitudinal direction of the base 80 approximately aligned with the X direction and the width direction 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 far 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.

Alternatively, instead of providing through holes in the bottom plate portion 15 of the box body 10, adhesive is poured from the outside into the four screw holes 81a on the four corner sides or into the four screw holes 81b on the side furthest from the four corners, and the boss portion 83 (see FIG. 11) is bonded to the bottom plate portion 15 of the box body 10 at the points where the boss portion 83 abuts. In this way, the base 80 can be fixed to the box body 10.

Figure 12 is a side view of the delivery box 1 as viewed from the outside in the Y direction, with the internal structure shown in solid lines. As shown in Figure 12, the bottom plate portion 15 of the box body 10 slopes upward as it approaches the rear. In addition, the base 80 tapers 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.

Next, the fixing structure of the door 40 and the fixing structure of the locking device 50 will be briefly described. Like the box body 10, the door 40 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 and 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 has a bottomed cylindrical hole 91 extending in the Z direction.

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 portion 90 of each hinge 5a and 5b inserted into the bottomed cylindrical hole 91 of the hinge attachment recess 42, the flat plate portion 92 is fastened and fixed to the screw hole 39 (see Figure 4) of the reinforcing frame 25 using a screw, thereby fixing the door 40 to the reinforcing frame 25 so that it can be opened and closed freely.

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 delivery boxes and can lock and unlock. For example, the locking device 50 may be configured with an electronic lock that allows the door 40 to be locked and unlocked electrically. Next, the locking and unlocking operations of the locking device 50 when it is an electronic lock will be briefly described without using any diagrams.

In this case, inside the locking device 50, there are arranged a power supply unit including a battery, a control device supplied with power from the power supply unit, an electric actuator including a solenoid or the like driven by the control device, and a locking mechanism. 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.

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 no longer interferes 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.

13 is a plan view of the delivery box 1 before the base 80 is attached, as seen 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 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 47 is located rearward, the reinforcing frame 25 can be used as a canopy. Therefore, the front plate 47 can be prevented from being exposed to direct sunlight or rainwater, and deterioration of the door 40 can be prevented. If this offset is not adopted, the door will interfere with the side plate, and the door will only open about 90° from the closed position.

Next, the high degree of freedom in 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 explained 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.

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.

Furthermore, referring again to FIG. 7, in a 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.

As shown in FIG. 17, a horizontally oriented delivery box 201 can be easily realized simply by changing the placement surface of the box body 10 and 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 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.

Thus, even if the delivery box is a horizontally placed delivery box 201, rainwater that falls on the top surface 12b can flow backward along the top surface 12b. This prevents rainwater from entering the delivery box 1, and also prevents rainwater from remaining on the top surface 12b and causing corrosion of the top surface. Since the delivery box 201 can share the door 40, reinforcing frame 25, and box body 10 with the delivery box 1, 101, it is possible to mass-produce the delivery box 1, 101, 201, which has a high degree of freedom in placement and is highly versatile.

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

When a free-stop hinge is used in a horizontally placed delivery box 201, the door 40 can be stopped at any position by static friction, improving convenience. It is not necessary to use a free-stop hinge, and the door 40 can be held open by hand or by using a stop bar. The door 40 can also be rotated upward by 90° or more and tilted backwards to prevent the door 40 from closing due to gravity.

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

Referring to FIG. 7, in this embodiment, in the box body 10, the inclination angle of the outer surface of the first side panel portion 12 in the X direction, the inclination angle of the outer surface of the second side panel portion 13 in the X direction, the inclination angle of the bottom surface 15b of the bottom panel portion 15 in the X direction, and the inclination angle of the top surface 19b of the top panel portion 19 in the X direction are all the same. Therefore, the same base 80 can be used when the delivery box is the vertical delivery box 1,101 and when it is the horizontal delivery box 201, which increases the versatility of the base 80 and makes it easier to mass-produce the base 80.

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 at least 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. Also, 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 position with a gap between them.

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 are arranged vertically in two tiers, and FIG. 21 is a diagram for explaining a case where the same delivery boxes 201 are arranged horizontally in two tiers. As shown in FIG. 21 and FIG. 22, in either the 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 between the lower delivery box 1,210 and the upper delivery box 1,210 so that they overlap with the 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 holes 81 (see FIG. 10).

Here, the four screw holes 81a (see FIG. 10) close to each corner can be used as the screw holes for this fixing, or the four screw holes 81b (see FIG. 10) away from each corner can be used. The upper base 80a and the upper surface of the lower delivery box 1,210 can be fixed with adhesive. Alternatively, a reinforcing plate can be fixed to the 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 of the lower delivery box 1,210, the upper base 80a, the bottom plate 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 can be screwed in with the same screw member (e.g., bolts).

In these embodiments, the upper base 80a placed 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, making it easy to manufacture multiple-tiered delivery boxes 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.

Next, the essential configurations and their effects for the delivery boxes 1, 101, and 201 of the present disclosure will be described. Note that, below, the essential configurations and their effects will be described using the vertically oriented delivery box 1, 101 as an example, but even in the case of the horizontally oriented delivery box 201, the essential configurations and their effects are the same as those for the vertically oriented delivery box 1, 101.

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 the opening edge portion 6a at the 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 allows the door 40 to be locked or unlocked. 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 this 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.

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 in the X direction, making it easy to assemble and suitable for mass production. In addition, the delivery box 1,101 is provided with 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, making it highly rigid. In addition, the box body 10 has a 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 a 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 either vertically or horizontally. For example, whether the delivery box 1, 101, 201 is arranged vertically or horizontally, the upper surface of the second reinforcing plate 60 or 70 can form the lower surface of the internal chamber 2. Therefore, the degree of freedom in arranging the delivery box 1, 101, 201 can be increased.

When the delivery box 1,101 is placed vertically, the first recess 16 forms the side fitting and fixing part, and the second recess 23 forms the bottom fitting and fixing part. However, when the delivery box 201 is placed horizontally, the second recess 23 forms the side fitting and fixing part, and the first recess 16 forms the bottom fitting and fixing part.

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

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 relative to the axis 76 that rotates the door 40.

With this configuration, the door 40 can be rotated 90° or more from the closed position, making it easier to store luggage in the internal chamber 2 and easier to remove luggage from the internal chamber 2.

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. 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 as it approaches 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.

With this configuration, whether the delivery box 1, 101, 201 is used in a vertical or horizontal orientation, the top surface is arranged to include the first inclined portion or the second inclined portion, allowing rainwater to flow smoothly along the top surface to the outside of the delivery box 1, 101, 201. This prevents rainwater from entering the delivery box 1, 101, 201, and also prevents rainwater from remaining on the top surface of the delivery box 1, 101, 201 and causing top surface corrosion.

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 that inclines toward the top plate portion 19 in the Z direction as it moves toward 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 that inclines toward the first side plate portion 12 in the width direction as it moves toward 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 on the entire surface of the bottom surface 15b, and the fourth inclined portion is configured on the entire surface of the outer surface 13b of the second side plate portion 13. However, the third inclined portion may be configured on a part of the bottom surface 15b, and the fourth inclined portion may be configured on a part of the outer surface 13b of the second side plate portion 13.

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 relative to the X direction, the second inclination angle of the second inclined portion relative to the X direction, the third inclination angle of the third inclined portion relative to the X direction, and the four inclination angles of the fourth inclined portion relative to the X direction are all approximately the same, not only can the versatility of the base 80 be increased, but the delivery box 1, 101, 201 can be realized that is symmetrical and aesthetically pleasing.

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 body 10 may further include an upper base 80a that is arranged to contact the top surface 19b and has an upper surface that extends in a direction approximately perpendicular to the Z direction.

With this configuration, as shown in Figures 20 and 21, delivery boxes 1, 101, and 201 can be stacked in two or more tiers depending on preference.

Note that this 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 this application and their equivalents.

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

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.

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 plate portions may not have an inclined portion. Also, only the top surface and the outer surface of one of the side plate portions may have an inclined portion. Or, the delivery box of the present disclosure may have no inclined portion on any of the top surface, bottom surface, and the pair of outer surfaces of the pair of side plate portions.
