Description

[Technical Field]

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

[0002] Foldable delivery boxes have been known in the past. For example, one proposed delivery box is fixed to the wall of a dwelling unit by a wall-side mounting fixture, is normally installed in a folded state, and when a package is delivered when the resident is not at home, is unfolded by the delivery company into an assembled state to store the package (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-003172 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in order to unfold the delivery box in Patent Document 1 into its assembled state, it is necessary to first open the top and bottom panels in the vertical direction, rotate the handle attached to the bottom panel to support it on the floor, and then pull out the side panels built into the main body cover to form the engagement surfaces of the delivery box. As such, assembling the delivery box requires multiple steps, which creates a problem of a heavy burden on the delivery company.

[0005] Furthermore, after collecting packages from the delivery box, the same multiple steps are required to return the delivery box to its folded state, making the folding process of the delivery box also burdensome.As a result, there was also the problem that the delivery box was left in an assembled state after the packages were collected, and the folding function of the delivery box was not utilized.

[0006] The present disclosure aims to provide a delivery box that is easy to unfold and fold. [Means for solving the problem]

[0007] The present disclosure relates to a delivery box comprising a front frame body having a door, a rear frame body, a connecting portion that connects the front frame body to the rear frame body so that the front frame body can be moved in the fore-and-aft direction, and a foldable storage portion attached to the front frame body and the rear frame body, wherein the storage portion is unfolded by moving the front frame body forward and folded by moving the front frame body backward.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings of the present disclosure, four predetermined directions that are perpendicular to one another are represented as the "Fr direction," "Rr direction," "R direction," and "L direction." The "Fr direction" indicates the front direction of the delivery box 1 where the door 4 through which packages are put in and taken out is located, the "Rr direction" indicates the back direction of the delivery box 1, the "R direction" indicates the right direction when looking at the delivery box 1 from the front, and the "L direction" indicates the left direction when looking at the delivery box 1 from the front.

[0010] As shown in Figures 1 and 2, the delivery box 1 of this embodiment is fixed to a floor surface (not shown) by a base member 6 and is installed and used outdoors. The delivery box can be installed anywhere on a floor surface, regardless of whether it has a roof or not, as long as the casters 9 can roll on the floor surface. The box main body 10 is made up of all the components except for the base member 6.

[0011] As shown in Fig. 3, delivery box 1 has a frame body 2, a connecting portion 3, an opening / closing door 4, a rear cover 5, a base member 6, and a storage portion 7. Frame body 2 includes a front frame body 2A and a rear frame body 2B. Frame body 2 is formed from a shaped material obtained by extruding a metal such as aluminum, for example, but is not limited to this.

[0012] The front frame 2A is configured by framing an upper frame 21, a lower frame 22, vertical frames 23 arranged in the left-right direction, and corner members 24 provided at the four corners of the front frame 2A in a generally rectangular shape. As shown in FIG. 4, the upper frame 21 has a main body portion 211 and a holding portion 212. As shown in FIG. 4, the main body portion 211 has an outer periphery portion 211a, a tapered surface 211b, an engaging surface portion 211c, an inner periphery portion 211d, a partition plate 211e, an engaged portion 211f, a clamping piece 211g, and a magnet 8. As will be described later, the front frame 2A and the rear frame 2B have the same structure, and therefore the outer periphery portion 211a is a flat portion on the outer periphery side of the front frame 2A, and the inner periphery portion 211d is a flat portion on the inner periphery side of the front frame 2A.

[0013] Tapered surface 211b is bent from outer periphery 211a to the outside (Fr direction) of delivery box 1 and is provided so as to slope downward, and similar tapered surfaces are provided on lower frame 22 and vertical frame 23, which will be described later. With this configuration, delivery box 1 has tapered surfaces in the circumferential direction on the front and back, which reduces the sense of weight of delivery box 1 and gives an overall light and soft impression, improving the design of delivery box 1. Engagement surface 211c is bent upward at a substantially right angle from outer periphery 211a and is a vertical surface exposed to the inside of storage section 7.

[0014] As shown in Fig. 4, the partition plate 211e extends in the left-right direction to separate the outer peripheral portion 211a and the inner peripheral portion 211d, and has a hollow portion H1 formed in the upper direction. As shown in Fig. 14, a magnet 8 is provided in the approximate center of the engagement surface portion 211c in the left-right direction. Returning to Fig. 4, the magnet 8 is installed in the hollow portion H1 through a rectangular notch provided in the engagement surface portion 211c and is fixed to the partition plate 211e with a screw.

[0015] An end of the inner peripheral portion 211d is bent upward at a substantially right angle to form a clamping piece 211g. The engagement surface portion 211c, the inner peripheral portion 211d, the partition plate 211e, the clamping piece 211g, and the holding portion 212 form a hollow portion H2, in which a fixed shaft 713 of the storage portion 7 (described later) is housed and locked. The engaged portion 211f protrudes vertically and is bent at a substantially right angle in the Rr direction. As shown in FIGS. 4 and 6, the holding portion 212 has a first locking piece 212a, a second locking piece 212b, and an inner peripheral surface 212c.

[0016] 4, the holder 212 is disposed so that the inner peripheral portion 211d of the main body 211 and the inner peripheral surface 212c are flush with each other, and is fixed to the main body 211 via a screw S1. The first locking piece 212a is formed by bending the Rr-direction end of the inner peripheral surface 212c upward in a generally Z-shape. The second locking piece 212b has the same shape as the first locking piece 212a, is provided to protrude from approximately the center of the inner peripheral surface 212c in the front-rear direction, and engages with the engaged portion 211f of the main body 211.

[0017] With this configuration, the first locking piece 212a can lock the fixed shaft 713 of the storage unit 7 in the hollow portion H2 with three flat portions configured in a substantially Z shape. Furthermore, the upper surface portion 71 of the storage unit 7 is clamped between the clamping piece 211g of the main body portion 211 and the first locking piece 212a of the holding portion 212, and the fixed shaft 713 can be reliably fixed in the hollow portion H2.

[0018] 4 and 6, the lower frame 22 has a main body portion 221 and a holding portion 222. The lower frame 22 is provided so as to be vertically symmetrical to the upper frame 21. The main body portion 221 of the lower frame 22 has an outer periphery portion 221a, a tapered surface 221b, an engagement surface portion 221c, an inner periphery portion 221d, a partition plate 221e, and a clamping piece 221f, which correspond to the outer periphery portion 211a, the tapered surface 211b, the engagement surface portion 211c, the inner periphery portion 211d, the partition plate 211e, and the clamping piece 211g of the upper frame 21, respectively.

[0019] The main body 221 of the lower frame 22 differs from the main body 211 of the upper frame 21 in that the lower frame 22 is provided with casters 9 instead of magnets 8, and that the height Y in the vertical direction of the tapered surface 221b is higher than the height X of the tapered surface 211b of the upper frame 21 and is equal to the vertical distance between the outer circumferential portion 221a and the partition plate 221e. The rest of the configuration of the main body 221 is the same as that of the main body 211 of the upper frame 21, so a description thereof will be omitted.

[0020] As shown in Fig. 2, the casters 9 are wheel units provided in pairs at both ends of the outer circumferential portion 221a. The casters 9 roll due to an external force, thereby moving the front frame 2A in the front-rear direction. As shown in Fig. 4, the height Y of the tapered surface 221b is set higher than the height X of the tapered surface 211b of the upper frame 21, so the casters 9 can be stored inside the main body 221.

[0021] 4, the holding portion 222 has a first locking piece 222a, a second locking piece 222b, and an inner circumferential surface 222c. The holding portion 222 of the lower frame 22 differs from the holding portion 212 of the upper frame 21 in that the inner circumferential surface 222c of the holding portion 222 is shorter than the inner circumferential surface 212c of the upper frame 21. The first locking piece 222a and the second locking piece 222b are formed by bending downward from both ends of the inner circumferential surface 222c.

[0022] With this configuration, the first locking piece 222a and the inner peripheral surface 222c are configured to have a substantially L-shape in the Fr direction, so there are no obstacles that could catch on the package when putting it in or taking it out of the delivery box 1, allowing for smooth putting in and taking out of the package. The rest of the configuration is the same as the holding portion 212 of the upper frame 21, so a description thereof will be omitted.

[0023] As shown in Figure 5, the pair of vertical frames 23 are arranged symmetrically to form the front frame 2A. The vertical frames 23 have a main body portion 231 and a holding portion 232. The main body portion 231 has an outer periphery portion 231a, a tapered surface 231b, a fixed portion 231c, an engaging surface portion 231d, an inner periphery portion 231e, an engaged portion 231f, a clamping piece 231g, a first side surface portion 231h, and a second side surface portion 231i. The outer periphery portion 231a is a flat portion on the outer periphery side of the front frame 2A, and the inner periphery portion 231e is a flat portion on the inner periphery side of the front frame 2A.

[0024] Tapered surface 231b is a tapered surface that slopes outward from vertical frame 23 as it moves from the front to the rear, and is configured to have the same height X as tapered surface 211b of upper frame 21. Fixed portion 231c is a vertical surface that extends inward perpendicular to outer periphery 231a, and when viewed from the left or right, fixed portion 231c is hidden by outer periphery 231a and cannot be seen. With this configuration, when connecting portion 3 (described later) and frame body 2 are connected via screws, as shown in Figures 1 and 2, fixed portion 231c to which the screws are fixed is hidden from the outside, thereby improving the design of delivery box 1.

[0025] As shown in FIG. 5, an end of the inner peripheral portion 231e is bent at a substantially right angle toward the outer periphery to form a clamping piece 231g. The first side surface portion 231h is a vertical surface that connects the fixed portion 231c and the engagement surface portion 231d at a substantially right angle. The engagement surface portion 231d, the first side surface portion 231h, the engagement surface portion 231d, the inner peripheral portion 231e, the clamping piece 231g, and the holding portion 232 form a hollow portion H2, in which a fixed shaft 733 of the storage portion 7 (described later) is housed and locked. The engaged portion 231f is provided to protrude in the vertical direction and is bent at a substantially right angle toward the Rr direction. The second side surface portion 231i is a vertical surface that connects the tapered surface 231b and the engaged portion 231f at a substantially right angle.

[0026] 5, the retaining portion 232 of the vertical frame 23 has a first locking piece 232a, a second locking piece 232b, and an inner peripheral surface 232c, which respectively correspond to the first locking piece 212a, the second locking piece 212b, and the inner peripheral surface 212c of the retaining portion 212 of the upper frame 21. The retaining portion 232 of the vertical frame 23 and the retaining portion 212 of the upper frame 21 have the same configuration and functional effects, so a description thereof will be omitted.

[0027] As shown in Figures 1 and 2, the corner member 24 is composed of an upper member 24A and a lower member 24B. As shown in Figure 7, the upper member 24A is a corner connector provided at two upper corners of the front frame 2A and connects both left and right ends of the upper frame 21 to the upper end of the paired vertical frame 23. The upper member 24A has a corner cap 241 and a connecting metal fitting 242. Note that Figure 7 shows an enlarged perspective view of the corner cap 241 and the connecting metal fitting 242 viewed from the opposite direction within frame A indicated by dashed lines.

[0028] As shown in FIGS. 7 to 9, corner cap 241 includes corner outer peripheral portion 241a, tapered surface 241b, first fitting portion 241c, and second fitting portion 241d. Corner cap 241 is integrally molded from an elastically deformable material. For example, but not limited to, a resin member may be used. First fitting portion 241c is provided in the Fr direction of corner cap 241, and second fitting portion 241d is provided in the Rr direction of corner cap 241. Tapered surface 241b has the same shape as the tapered surfaces of upper frame 21 and vertical frame 23, and can form a tapered surface that is continuously formed in the circumferential direction of delivery box 1.

[0029] The corner outer periphery 241a is an outer peripheral surface portion that forms a corner of the frame body 2A. The corner outer periphery 241a is configured to have an arc shape when viewed from the front. With this configuration, the use of elegant curves at the corners of the frame body improves the design of the delivery box 1. The tapered surface 241b slopes downward from the corner outer periphery 241a in the Fr direction and is bent in the Rr direction. A first fitting portion 241c is formed on the back surface where the tapered surface 241b is bent. The first fitting portion 241c includes a fixed shaft 241e and a mating fixed piece 241f. A substantially L-shaped gap G is formed between the fixed shaft 241e and the fixed piece 241f. The second fitting portion 241d is formed on the bottom surface of the corner cap 241 and includes a hook piece 241g whose tip in the Fr direction is bent in a substantially L-shape.

[0030] As shown in Figure 7, the connecting fitting 242 is a connecting member having a substantially L-shape. The connecting fitting 242 is a bent sheet metal member and may be made of any metal material, such as stainless steel (SUS). The connecting fitting 242 has a first fixing portion 242a and a second fixing portion 242b. The first fixing portion 242a is made of sheet metal bent into a substantially L-shape, and a plurality of screw holes used for fixing to the upper frame 21 are provided on the upper surface of the bent first fixing portion 242a.

[0031] 5, the second fixing portion 242b is made of sheet metal bent into a substantially L-shape, and as shown in Fig. 5, a plurality of screw holes are provided on the two bent surfaces to be used for fixing to the second side surface portion 231i and the engaged portion 231f of the vertical frame 23. In order to be fixed to the vertical frame 23, the second fixing portion 242b is bent at a substantially right angle from the first fixing portion 242a.

[0032] As shown in Fig. 7, the upper frame 21 and the vertical frames 23 arranged on the left and right sides are connected and fixed by two connecting fittings 242. As shown in Fig. 9, the first fixing portion 242a and the second fixing portion 242b of the connecting fitting 242 are fitted into the gap G provided in the first fitting portion 241c of the corner cap 241, thereby securely fixing the frame 21 to the frame. The upper end of the vertical frame 23 is fixed by a hook piece 241g formed on the second fitting portion 241d of the corner cap 241.

[0033] With this configuration, the upper frame 21 and the paired vertical frame 23 are securely fixed together by fitting the connecting fittings 242 into the corner caps 241, and the front frame 2A is formed via the upper member 24A. Furthermore, the first fixing portion 242a and the second fixing portion 242b of the connecting fittings 242 are fixed to the front frame 2A by three surfaces: the upper frame 21, and the second side surface portion 231i and the engaged portion 231f of the vertical frame 23. This suppresses twisting of the connecting fittings 242 and improves the durability of the front frame 2A.

[0034] Corner cap 241 is made of a flexible material that is capable of elastic deformation, so it can be easily fitted to connecting fitting 242 without using fasteners such as screws. This configuration improves the ease of installation of delivery box 1 and reduces the number of steps required.

[0035] The difference between the lower member 24B and the upper member 24A is that the corner outer periphery 241a and tapered surface 241b of the upper member 24A are configured to match the height X of the tapered surface 211b of the upper frame 21, as shown in Figure 6, whereas the height of the tapered surface and corner outer periphery of the lower member 24B is set to match the height of the tapered surface 221b of the lower frame 22.

[0036] The rest of the configuration is the same as that of the upper member 24A, so a description thereof will be omitted. The configuration that combines resin members and metal members improves the ease of installation of the front frame body 2A, and the corners of the frame body can be formed with soft curved surfaces made of resin, giving the frame body 2A a luxurious feel and improving the design of the delivery box 1.

[0037] As shown in Figure 3, the rear frame 2B is a component that is installed in the Rr direction of the delivery box 1 so as to be symmetrical in the front-to-rear direction with the front frame 2A, and constitutes the frame 2. The rear frame 2B differs from the front frame 2A in that the rear frame 2B does not have casters 9. As the rest of the configuration is the same as the front frame 2A, a description thereof will be omitted.

[0038] As shown in FIG. 3, the connecting portion 3 is a member provided between the front frame 2A and the rear frame 2B and connects the two frames. The connecting portion 3 has a first link member 31, a second link member 32, a rail portion 33, and a rotating shaft 34. As shown in FIGS. 1 and 2, the first link member 31 and the second link member 32 are provided so as to intersect with each other in a side view, and the two link members are rotatably connected via the rotating shaft 34. As shown in FIG. 3, four rail portions 33 are provided at the lower end portions of the connected first link member 31 and second link member 32, respectively.

[0039] 5, the first link member 31 is provided on the outer periphery side of the outer periphery 231a of the vertical frame 23 provided on the rear frame 2B. The second link member 32 is provided to extend in the Rr direction from the fixed portion 231c of the vertical frame 23 provided on the front frame 2A, and is provided on the inner periphery side of the outer periphery 231a of the front frame 2A. In this way, the two link members are arranged to intersect with each other around the rotation shaft 34 without contacting each other.

[0040] As shown in Figures 1 and 2, the first link member 31 has one handle portion 31A, two arm portions 31B arranged on the left and right, a corner connector 313, and an end cap 314. The first link member is configured in a generally U-shape, with the handle portion 31A located at the center of the upper part, and the paired arm portions 31B connected at a generally right angle downward from both ends of the handle portion 31A via the corner connectors 313. End caps 314 are connected to the lower ends of the arm portions 31B, respectively. The handle portion 31A is arranged to extend in the left-right direction.

[0041] As shown in Figures 10 and 11, the handle portion 31A has a cover material 31a and a base material 31b. Although Figures 10 and 11 show the base material pulled out further toward the corner connector 313 than the cover material, the base material and cover material are the same length, and the end faces of both materials are normally used flush with each other. In Figure 10, the lower end of the cover material 31a of the arm portion 31B (described later) is indicated by a two-dot chain line.

[0042] 10 and 11, the cover material 31a is formed of a shaped material obtained by extruding a metal such as aluminum, but is not limited to this. The cover material 31a has an outer periphery 311c, a mating tapered surface 311d, and an engagement groove 311e. The outer periphery 311c is a flat portion on the outer periphery of the first link member 31.

[0043] Tapered surface 311d is a tapered surface that slopes downward from outer periphery 311c in the front-to-rear direction, and the two tapered surfaces have the same shape and are provided symmetrically in the front-to-rear direction. This configuration gives first link member 31 a light and soft impression and makes handle portion 31A easier to grip. Providing tapered surface 311d improves the design and usability of delivery box 1.

[0044] 11, the engagement groove 311e is a recessed engagement portion formed continuously from the tapered surface 311d toward the inner circumferential side. The base material 31b is engaged with the recessed portion formed in the engagement groove 311e, thereby reliably fixing the cover material 31a and the base material 31b together.

[0045] 10 and 11, the base member 31b is a rectangular cylindrical member, and is formed from a shaped member obtained by extruding a metal such as aluminum, for example, but not limited to, the base member 31b. The base member 31b is engaged with the cover member 31a when in use. The base member 31b has a pair of first and second through holes 311f and 311g at both ends in the longitudinal direction.

[0046] The arm portion 31B differs from the handle portion 31A in that the arm portion 31B is longer than the handle portion 31A. The other configurations are the same, so a description thereof will be omitted. The mating arm portion 31B is connected to both left and right ends of the handle portion 31A via corner connectors 313, which will be described later.

[0047] In the first link member 31 of the present disclosure, the lengths of the arm portion 31B and the handle portion 31A are not limited to this. Depending on the size and shape of the delivery box, for example, the handle portion 31A may be longer than the arm portion 31B, or the arm portion 31B and the handle portion 31A may be the same length.

[0048] 10 and 11, the corner connector 313 is a corner connection component that is molded as a single unit. Any elastically deformable material may be used, such as, but not limited to, resin. The corner connector 313 has a main body 313a, a mating tapered surface 313b, a mating connecting piece 313c, a protrusion 313d, and a notch 313e.

[0049] Main body 313a is a bent member configured to have an arc shape when viewed from the front. The corners of first link member 31 are configured with graceful arc-shaped curved surfaces, giving first link member 31 a soft impression and improving the design of delivery box 1. Tapered surface 313b has the same shape as tapered surface 311d of handle portion 31A. With this configuration, tapered surface 313b is provided in the front-rear direction from the flat portion on the outer periphery of first link member 31, and can form a tapered surface that is continuously formed in the circumferential direction.

[0050] The connecting pieces 313c are generally rectangular plate members protruding from both ends of the main body 313a. Because the main body 313a has an arc shape that forms corners, the paired connecting pieces 313c extend in directions that form a generally right angle with each other. The connecting piece 313c protruding in the R direction is connected to the L direction end of the handle 31A, and the connecting piece 313c protruding downward is connected to the upper end of the arm 31B.

[0051] 10 and 11, the protrusions 313d are paired cylindrical protrusions provided side by side in the front-to-rear direction on the end of the connecting piece 313c. The protrusions 313d are engaged with the through-hole 311f of the handle portion 31A and the through-hole of the arm portion 312. With this configuration, when assembling the first link member 31, the positions of the corner connector 313, the handle portion 31A, and the arm portion 31B can be reliably determined.

[0052] As shown in FIG. 11, the notches 313e are slit-shaped and extend through the connecting piece 313c in the left-right direction. Four notches 313e are provided on the top surface of the connecting piece 313c. This configuration allows the connecting piece 313c to elastically deform like a spring. Furthermore, even when an impact or the like is applied to the first link member 31, the spring effect of the notches 313e protects the joint, thereby improving the durability of the first link member 31.

[0053] As described above, the corner connector 313 is engaged with the handle portion 31A and the arm portion 31B via the protrusion 313d, and can also be secured to the base materials of the handle portion 31A and the arm portion 31B by threading a screw through the second through-hole 311g of the cover material 31a. This configuration more firmly secures the corner connector 313 to the handle portion 31A and the arm portion 31B, forming the first link member 31.

[0054] Furthermore, the synergistic effect of the protrusions 313d and notches 313e described above prevents deformation such as misalignment or twisting of each part of the connected first link member 31 when the delivery box 1 is in use, and enables the fastening by the screws to be maintained even more firmly. With this configuration, the corner connector 313 can be firmly joined to the handle portion 31A and the arm portion 31B to form the first link member 31 without using dedicated fastening hardware.

[0055] As shown in FIGS. 10 and 11 , the end cap 314 is a lid member attached to the lower end of the mating arm portion 31B. Like the corner connector 313, any elastically deformable material may be used, including, but not limited to, resin. The end cap 314 has a main body 314a, a tapered surface 314b, a connecting piece 314c, a protrusion 314d, and a notch 314e. The main body 314a is configured in a generally semicircular shape and is attached to the lower end of the first link member 31. The tapered surface 314b is tapered downward from the main body 314a toward the outer periphery so as to connect with the tapered surface 311d of the arm portion 31B.

[0056] The difference between connecting piece 314c of end cap 314 and connecting piece 313c of corner connector 313 is that connecting piece 314c is not fixed with a screw and has a notch between the pair of protrusions 314d. The rest of the configuration is the same as connecting piece 313c of corner connector 313, with protrusions 314d and notch 314e of end cap 314 corresponding to protrusions 313d and notch 313e of corner connector 313. The configuration and functional effects are the same, so a description will be omitted.

[0057] With this configuration, the end of first link member 31 is formed with an elegantly curved arc-shaped surface, giving delivery box 1 a delicate and soft impression and improving the design of delivery box 1. Furthermore, end cap 314 can be attached to arm portion 31B via protrusion 314d without using fasteners such as screws, making installation extremely easy and reducing the amount of work required.

[0058] 3, the second link member 32 is disposed so as to intersect with the first link member 31 in a side view. The second link member 32 has a pair of arm portions 321. The arm portions 321 are disposed so as to be symmetrical in the left-right direction, and are rotatably fixed to the arm portion 31B of the first link member 31 via a rotation shaft 34.

[0059] The arm portion 321 is a long sheet metal member and may be made of any metal material, such as stainless steel (SUS). A connecting fitting 321a is rotatably attached to the upper end of the arm portion 321. The connecting fitting 321a has multiple screw holes on the surface facing the rear frame 2B. The upper end of the arm portion 321 is fixed to the fixed portion 231c of the vertical frame 23 that constitutes the rear frame 2B via screws.

[0060] 12, the rotating shaft 34 is inserted into the arm portion 321 of the second link member 32 from the inner circumferential side, and is fixed to the hollow portion of the base material 31b provided on the arm portion 31B of the first link member 31. With this configuration, the rotating shaft 34 cannot be seen from the outer circumferential side, so the cover material 31a of the first link member 31 can be configured neatly, and the design of the delivery box 1 can be improved.

[0061] 3, the rail portion 33 is a bent sheet metal member formed by bending the member at a substantially right angle to the vertical direction. Any metal material may be used, for example, stainless steel (SUS). The rail portion 33 is attached to the lower end portions g of the first link member 31 and the second link member 32, and is connected to the lower end portions of the respective link members via pop nuts 35. The rail portion 33 is formed of two surfaces that are substantially L-shaped in plan view, and has a fixing surface 331 and a rail surface 332.

[0062] The fixing surface 331 is a surface facing the vertical frame 23 of the front frame 2A and the rear frame 2B, and has a plurality of through holes 331a. The rail surface 332 is a surface exposed toward the outer periphery of the frame 2, and has elongated holes 332b. As shown in Figures 3 and 12, the fixing surface 331 is fixed to the fixed portion 231c of the vertical frame 23 by inserting a screw into the through hole 331a.

[0063] Returning to Figure 3, the POP nut 35 is a fixing member that has a flange on its head. The elongated hole 332b is formed with a width that allows the threaded portion of the POP nut 35 to pass through, and the flange on its head prevents the POP nut 35 from falling out of the elongated hole 332b, and anchors the POP nut 35 to the rail portion 33. The first link member 31 and the second link member 32 are anchored to the rail portion 33 via the POP nut 35. Because the POP nut 35 is anchored by the elongated hole 332b so as to be movable in the up-down direction, the front frame 2A and the rear frame 2B are configured to be movable in the front-to-rear direction via the connecting portion 3.

[0064] As shown in FIG. 3, the door 4 is a single-wing door installed on the front side of the front frame 2A. The door 4 is formed by processing a sheet metal member. Any metal material may be used for the sheet metal member, but for example, stainless steel (SUS) can be used. The door 4 has a panel portion 41, a shaft portion 42, and a lock storage portion 43.

[0065] The shaft 42 is fixed to the upper frame 21 and the lower frame 22 of the front frame body 2A, and as shown in Fig. 13, the door 4 opens to the outside of the delivery box 1 with the shaft 42 as the axis. In this embodiment, the shaft 42 is provided at the R-direction end of the door 4, but the door 4 may open to either the left or right depending on the installation location. For example, the shaft 42 may be provided at the L-direction end of the revolving door 4.

[0066] 3 and 4, the lock storage unit 43 is opened at the top of the panel unit 41 in the L direction and protrudes in the Rr direction of the panel unit 41. The lock storage unit 43 includes a lock lid 44. The lock lid 44 may be provided in any manner relative to the opening of the lock storage unit 43, and may be, for example, a one-sided lid using a hinge or a sliding lid. The location at which the lock storage unit 43 is installed is not limited to this; for example, the lock storage unit 43 may be provided in approximately the vertical center of the panel unit 41 in the R direction.

[0067] The lock storage section 43 stores the padlock 45 of the opening and closing door 4. The key used in the present disclosure is not limited to the padlock 45, and any key can be used, such as a combination lock, an electronic lock, or a variable button lock, as long as it can achieve the purpose of crime prevention. The shape of the lock storage section 43 may also be changed to match the key.

[0068] As shown in Figure 13, the lock receiving portion 46 of the padlock 45 is provided in the retaining portion 232 of the vertical frame 23. The location where the lock receiving portion 46 is installed is not limited to this, and the lock receiving portion 46 may be provided in any position to suit the shape of the lock. The lock receiving portion 46 is a concave horizontal hole made of resin, and houses a deadbolt that pops out from the lock when locked. The shape of the lock receiving portion 46 is also not limited to this, and the size and depth may be changed to suit the lock.

[0069] As shown in Figures 3 and 14, the rear cover 5 is a cover member provided in the Rr direction of the rear frame 2B. The rear cover 5 is formed by processing a sheet metal member. Any metal material may be used for the sheet metal member, but for example, stainless steel (SUS) can be used. The rear cover 5 has a rear panel 51, an upper surface portion 52, and side surfaces 53 provided in the left and right directions.

[0070] The rear panel 51 is a surface material portion facing the rear frame 2B. The top surface portion 52 is a flat portion formed by bending the upper end of the rear panel 51 at approximately a right angle in the Fr direction. The side surface portion 53 has a first through hole 53a, a fixing portion 53b, and a second through hole 53c. The side surface portion 53 is formed by bending the left and right ends of the rear panel 51 at approximately a right angle in the Fr direction. A plurality of first through holes 53a are provided in the lower portion of the side surface portion 53.

[0071] The fixing portion 53b is formed by bending the tip of the side surface portion 53 further toward the outer periphery of the frame 2. The fixing portion 53b is a flat portion facing the rear frame 2B, and is provided with a plurality of second through holes 53c extending in the vertical direction.

[0072] 4 and 14, the base member 6 is disposed on the lower surface of the rear frame 2B so as to extend in the left-right direction, and is fixed by being engaged with the outer peripheral portion 221a and the tapered surface 221b of the lower frame 22 that constitutes the rear frame 2B. The base member 6 is formed of a shaped member obtained by extruding a metal such as aluminum, for example, but is not limited to this.

[0073] As shown in Figures 3 and 13, the base member 6 is formed in a substantially L-shape and is fixed to a floor surface (not shown). The base member 6 has a fixing portion 61 and a wall portion 62. The fixing portion 61 is a flat portion that is placed on the floor surface, and a protrusion 611 is formed at the tip in the Fr direction. The fixing portion 61 has the protrusion 611 on the travel path of the caster 9. The back surface of the fixing portion 61 is adhered to the floor surface via an adhesive, so that the base member 6 can be fixed and installed in any location.

[0074] This configuration eliminates the need to drill holes in the building or exterior, allowing delivery box 1 to be easily installed anywhere. Furthermore, the method of fixing delivery box 1 is not limited to adhesive fixation. For example, when installing delivery box 1 on a floor where adhesive cannot be used, fixing portion 61 to the floor surface may be fixed with bolts. Protrusion 611 is configured in a roughly triangular shape, and can engage caster 9 when delivery box 1 is in use, as described below.

[0075] The wall portion 62 stands upward at a substantially right angle from the Rr-direction end of the fixing portion 61. As shown in Fig. 14, a plurality of tapping holes 621 are formed at both left-right ends of the wall portion 62. As shown in Fig. 14, the rear cover 5 and the base member 6 are joined by fixing the first through-holes 53a of the rear cover 5 to the tapping holes 621 of the wall portion 62 with tapping screws.

[0076] As shown in Figures 5 and 14, screws are inserted into the second through-holes 53c of the rear cover 5 and fixed to the vertical frame 23 of the rear frame 2B, thereby joining the rear cover 5 and the rear frame 2B. With this configuration, the base member 6 is securely joined to the rear frame 2B. Because the base member 6 is adhesively fixed to the floor, the rear cover 5 and the rear frame 2B are also fixed to the floor, and their movement is controlled. The base member 6 allows only the front frame 2A and the opening / closing door 4 fixed to the front frame 2A, the connecting portion 3, and the storage portion 7, which will be described later, to be movable in the front-to-rear direction of the delivery box 1.

[0077] 4 and 5, a gap Z is provided between the rear panel 51 of the rear cover 5 and the wall 62 of the base member 6. This gap Z forms an exhaust duct, and air stagnating inside the storage section 7 can be exhausted to the outside space via the wall 62. For example, even when the storage section 7 contracts in the Rr direction due to rotation of the connecting part 3, air inside the storage section 7 can be exhausted via the wall 62. This configuration allows the connecting part 3 to rotate smoothly without air stagnating inside the storage section 7.

[0078] As shown in FIGS. 3 and 6, the storage compartment 7 is a sheet-like member formed into a rectangular tube, and luggage is stored in the hollow space. The storage compartment 7 is formed using fabric. Examples of fabrics that can be used include polyester, nylon, cotton, and polycotton, but any fabric may be used. Furthermore, a fabric that is both lightweight and water-resistant is preferable, and the surface may be coated with a water-repellent coating agent or the like.

[0079] The storage section 7 has a top surface section 71, a bottom surface section 72, and side surface sections 73 arranged on the left and right. As shown in Fig. 15, the top surface section 71 has a sheet material 711, a reinforcing section 712, and a fixed shaft 713. The reinforcing section 712 has a layered structure in which a reinforcing material 712a is placed on the top surface of the sheet material 711, the top surface of the reinforcing material 712a is further covered with a cover material 712b, and an end of the cover material 712b is welded to the sheet material 711.

[0080] Reinforcing material 712a is formed of a resin plate material such as plastic cardboard (pladan), but the present disclosure is not limited to this. Any plate material can be used for reinforcing material 712a as long as it is lightweight and has enough rigidity to maintain its shape. Furthermore, cover material 712b may be made of the same material as sheet material 711, or may be made of a different material.

[0081] 3, the reinforcing portions 712 are arranged in front of and behind the top surface portion 71 so that the pair of rectangular shapes extend in the left-right direction. Between the reinforcing portions 712, the sheet material 711 is exposed so as to extend in the left-right direction. With this configuration, the reinforcing portions 712 of the storage portion 7 maintain a fixed planar shape in any state, and only the sheet material 711 can be deformed to form the top surface portion 71.

[0082] 15, the fixed shaft 713 includes a bag portion 713a and a tube material 713b. The bag portion 713a is a cylindrical bag portion formed to extend in the left-right direction, continuing from the front-rear end of the upper surface portion 71. The end of the bag portion 713a may be closed by gluing or sewing. As long as the hollow portion of the bag portion 713a is securely maintained, the end may be treated in any manner.

[0083] The tube material 713b is a core material placed in the hollow portion of the bag portion 713a. The tube material 713b is cylindrical, and may be, for example, a hard polyethylene tube, but is not limited to this. Any material may be used as the core material as long as it is cylindrical and has sufficient flexibility. As shown in FIG. 4, the fixed shaft 713 is housed and locked in the hollow portion H2 of the upper frame 21. This structure allows the storage portion 7 to be attached to the frame body 2.

[0084] The bottom surface portion 72 differs from the top surface portion 71 in that the bottom surface portion 72 further includes leg portions 724. The sheet material 721, reinforcing portion 722, and fixed shaft 723 of the bottom surface portion 72 correspond to the sheet material 711, reinforcing portion 712, and fixed shaft 713 of the top surface portion 71, and have the same configuration and functional effect, so a description thereof will be omitted. As shown in FIGS. 2 to 4, the leg portions 724 are elastic members formed of, for example, rubber. However, the leg portions 724 of the present disclosure are not limited to this and may be made of any elastic cushioning material.

[0085] A plurality of legs 724 are evenly spaced and joined to the reinforcing portion 722. The legs 724 can prevent the bottom portion 72 from bending downward due to the weight of the luggage when the luggage is placed in the storage portion 7. This configuration prevents the deposited luggage from colliding with the ground, and the cushioning effect of the legs 724 safely protects the luggage, improving the usability of the delivery box 1.

[0086] The difference between the side surface portion 73 and the top surface portion 71 is the shape of the reinforcing portion. The sheet material 731 and fixed shaft 733 of the side surface portion 73 correspond to the sheet material 711 and fixed shaft 713 of the top surface portion 71, and other configurations and functional effects are the same, so explanations will be omitted. The side surface portion 73 has a pair of reinforcing portions 732. The reinforcing portions 732 have an isosceles trapezoidal shape, with the long and short sides of the isosceles trapezoid extending in the up-down direction. The pair of reinforcing portions 732 are arranged symmetrically in the front-to-back direction, with the short sides facing toward the center of the side surface portion 73.

[0087] This configuration allows the storage section 7 to be made extremely lightweight, thereby reducing the weight of the delivery box 1. Furthermore, by using fabric for the storage section, the delivery box 1 becomes easier to operate and can be operated with less force, thereby improving the usability of the delivery box 1.

[0088] Next, a method of using the delivery box 1 will be described in detail with reference to the drawings. As shown in Figures 16 and 17, the delivery box 1 is installed in a building in a folded state before use. As shown in Figure 19, in the folded state, the first link member 31 of the connecting portion 3 is positioned more outer than the outer peripheral portion 231a of the vertical frame 23, and the second link member 32 is positioned between the fixed portions 231c of the paired vertical frame 23, and is shielded by the first link member 31, so it cannot be seen from the outside.

[0089] With this configuration, when the box is folded, only the first link member 31 of the connecting portion 3 is visible, and the second link member 32, which is not necessary for operation, is hidden, giving the impression of being neat and easy to understand. In addition, by joining the front frame body 2A and the rear frame body 2B in the front-to-rear direction and folding them, the delivery box 1 can be configured to be very compact, improving the design and usability of the delivery box 1.

[0090] 18, in the folded state, the magnets 8 provided on the paired upper frames 21 attract each other, preventing the front frame 2A and the rear frame 2B from opening and separating. Furthermore, because the box is held in place by magnets, the attraction between the magnets 8 can be easily released by applying a little force, improving the operability of the delivery box 1.

[0091] As described above, the casters 9 are provided on the lower frame 22 of the front frame 2A so as to come into contact with the floor surface (not shown). In the folded state, the casters 9 are positioned on the fixed portions 61 of the base member 6, and the wheels of the casters 9 are locked by the protrusions 611 so as not to move in the Fr direction. Because the protrusions 611 are configured as gently inclined surfaces, the casters 9 can climb over the protrusions 611 with the application of a slight force.

[0092] With this configuration, when the chair is folded, the casters 9 move in the Fr direction, preventing the front frame 2A and the rear frame 2B from opening and separating. Also, because the base member 6 is fixed to the floor, the rear frame 2B fixed to the base member 6 can remain fixed. In the frame 2, only the front frame 2A is configured to be movable in the front-rear direction via the casters 9.

[0093] 16, in the folded state, the first link member 31 of the connecting portion 3 is arranged to surround the frame body 2. The handle portion 31A protrudes upward and extends in the left-right direction, so that, for example, a delivery person can intuitively grasp the handle portion 31A.

[0094] As shown in Figure 20, the delivery box 1 on the right is in an open state. When the storage compartment 7 is fully open, the first link member 31 and the second link member 32 of the connecting part 3 move forward and backward while crossing each other, unfolding the storage compartment 7. In this state, the pop nut 35 provided on the rail part 33 is engaged with the uppermost end of the elongated hole 332b.

[0095] The delivery box 1 on the left is shown in a folded state. The lower portion of arm portion 31B of the folded delivery box is indicated by a two-dot chain line. When delivery box 1 is in a folded state, pop nut 35 provided on rail portion 33 is located at the bottom end of elongated hole 332b. When a user positions themselves in front of delivery box 1 and pulls handle portion 31A toward the front (toward the user), first link member 31 rotates in the direction of arrow F around rotation shaft 34, and pop nut 35, which was located at the bottom end of elongated hole 332b, slides in conjunction with first link member 31 to the top of elongated hole 332b.

[0096] As the first link member 31 rotates, the caster 9 attached to the front frame 2A is released from the base member 6 and moves in the Fr direction. Because the caster 9 rolls on the floor, it is possible to continue pulling the handle portion 31A toward the user with a very light force. The second link member 32 has one end joined to the front frame 2A and is connected to the first link member 31 via the rotation shaft 34, so it follows the rotation of the first link member 31. As a result, the second link member 32 also rotates in the direction of arrow O around the rotation shaft 34.

[0097] At this time, the pop nut 35 located at the lowest end of the elongated hole 332b in the rail portion 33 provided on the second link member also slides toward the top of the elongated hole 332b in conjunction with the second link member 32. With this configuration, the folded delivery box 1 can be easily unfolded into a storable state with a single action of simply pulling the handle portion 31A forward from the front of the delivery box 1.

[0098] 18 and 19, when delivery box 1 is folded, storage section 7 is also folded and stored inside frame 2. At this time, reinforcing sections 712, 722, and 732 maintain their plate shape without deformation due to the effects of reinforcing members 712a, 722a, and 732a. As shown in FIG. 21, storage section 7 is folded in four directions when viewed from the front, but reinforcing sections 712, 722, and 732 are stored in a folded-over state without bending and maintaining their shape.

[0099] 22, by applying a pulling force in the Fr direction to the folded storage section 7, fixed shafts 713 and 723 on the front frame 2A side move in the Fr direction, and sheet materials 711, 721, and 731 unfold into a flat state following the movements of fixed shafts 713, 723, and 733. Reinforcing portions 712, 722, and 732, which were folded and stored, are also unfolded in the same way, and storage section 7 can be configured into a storable state.

[0100] As shown in FIG. 23, the fixed shaft 713 of the storage unit 7 is engaged with the hollow portion H2 of the frame body 2. Similarly, as shown in FIGS. 18 and 19, the fixed shafts 723 and 733 are also engaged with the hollow portion H2 of the frame body 2. This allows the storage unit 7 to be unfolded in the Fr direction in response to the operation of the handle portion 31A. With this configuration, the storage unit 7 can be easily folded into a predetermined shape with a single action of simply pulling the handle portion 31A from the front of the delivery box 1 forward, without any external manipulation of the fabric. Because the storage unit 7 is made of lightweight fabric, the handle portion 31A can be pulled with very little force without feeling the weight of the storage unit 7.

[0101] Through the above-described operations, delivery box 1 can be put into a storable state with a single action of simply pulling handle 31A forward from the front of delivery box 1. After delivery box 1 is unfolded, door 4 is opened, the package is stored in the hollow space of storage section 7, and the package is locked according to the type of lock provided, completing the deposit of the package.

[0102] Next, we will explain how to return delivery box 1 to its folded state after the deposited luggage has been removed from storage section 7. To fold delivery box 1, the user simply performs the reverse procedure of the procedure for opening it to a storable state described above. As shown in Figure 1, with delivery box 1 in a state where opening and closing door 4 is closed, the user simply positions themselves in front of delivery box 1 and pushes handle portion 31A toward the back (rear).

[0103] This operation causes the connecting parts 3 to move the front frame 2A toward the rear via the casters 9. As shown in Figure 22, in conjunction with the movement of the front frame 2A, the fabric is folded from four directions toward the inside of the storage section 7 while maintaining the shapes of the reinforcing parts 712, 722, and 732 of the storage section 7. Bending deformation is applied only to the exposed surfaces of the sheet materials 711, 721, and 731, and the reinforcing parts 712, 722, and 732 are stored inside the frame 2 in a folded manner.

[0104] Sheet materials 711, 721, and 731 are folded along creases that follow reinforcing materials 712a, 722a, and 732a, so that storage section 7 is always folded into a pre-defined shape and stored in frame body 2. With this configuration, storage section 7 is always folded into the same shape and stored with a single action of simply pulling handle portion 31A from the front of delivery box 1 forward, without touching the fabric, making delivery box 1 extremely easy to fold.

[0105] 4 and 5, when the storage section 7 is folded in the Rr direction, air accumulated inside the storage section 7 is discharged through a gap Z provided between the rear panel 51 of the rear cover 5 and the wall portion 62 of the base member 6. In other words, the gap Z serves as an air exhaust port. If the gap Z is not provided, there are few outlets for the air accumulated in the storage section 7, and resistance due to air pressure may occur, which may increase the load required to fold the storage section 7 (the force to press on the handle portion 31A).

[0106] With this configuration, air accumulated in the storage compartment 7 is smoothly discharged, and the storage compartment 7 can be easily folded by simply gently pushing the handle portion 31A toward the rear. Furthermore, as shown in FIG. 18 , simply by gently pushing the handle portion 31A toward the rear, the caster 9 travels along the fixed portion 61 of the base member 6 and overcomes the protrusion 611. As the caster 9 rolls, the front frame 2A abuts against the rear frame 2B, and the upper frame 21 and the upper frame 21 are joined together via the magnet 8.

[0107] When the upper frames 21 are joined together, the casters 9 also stop rolling. The casters 9 are locked by the protrusions 611 of the base member 6, preventing them from returning to the Fr direction. This configuration ensures that the front frame body 2A and the rear frame body 2B are securely joined together without separating. By performing the above operations, the delivery box 1 is configured into a folded state as shown in Figures 16 and 17.

[0108] According to the method of using delivery box 1 described above, delivery box 1 can be folded or unfolded into a storable state with just one action: lightly pushing or pulling handle portion 31A. Delivery box 1 is configured to be foldable with just a simple operation of handle portion 31A, so no cumbersome work is required. In addition, because storage portion 7 is made of fabric, it is lightweight and very easy to handle.

[0109] The base member 6 is attached to the building by adhesive, so no special construction is required for installation. This allows end users to easily install the delivery locker 1. Since the delivery locker 1 does not require strong force or difficult operations, it can be used by anyone and in a wide range of places.

[0110] Delivery box 1 has a very neat and compact shape when storage section 7 is folded, so it can be installed in narrow spaces where it would be difficult to install a delivery box. In addition, because it has a delicate design with excellent aesthetic appeal, it has the effect of not spoiling the atmosphere of the entrance even if delivery box 1 is installed later.

[0111] As described above, the storage unit 7 is configured to be detachable and independent from the delivery box 1. Because the storage unit 7 is made of fabric, it is conceivable that the fabric may become dirty or torn due to, for example, aging. In such a case, the storage unit 7 can be easily removed from the delivery box 1 and reinstalled in the delivery box 1. A method for replacing the storage unit 7 will be described below.

[0112] 6, the rear frame 2B is composed of a main body 211 and a holding portion 212, and a rear cover 5 is provided in the Rr direction of the rear frame 2B. By removing the rear cover 5 and the holding portions 212 of the front frame 2A and rear frame 2B, the storage portion 7 can be removed independently from the delivery box 1.

[0113] As shown in FIG. 23, the fixed shaft 713 of the storage section 7 is engaged with a hollow portion H2 formed in the frame 2, thereby detachably attaching the storage section 7 to the front frame 2A and the rear frame 2B. A hollow portion H2 is formed in each of the front frame 2A and the rear frame 2B, and the paired fixed shaft 713 is engaged therein. First, the screws securing the rear cover 5 are removed, and the rear cover 5 is removed from the rear frame 2B. As shown in FIG. 6, removing the rear cover 5 exposes the holding portions 212, 222, and 232 on the rear surface of the rear frame 2B. As shown in FIG. 23, the holding portion 212 is fixed to the main body 211 with a screw S1.

[0114] By removing the screw S1 and removing the holding portion 212, the fixed shaft 713 of the storage section 7 can be released from the rear frame 2B. The holding portions 222 and 232 of the frame 2 and the fixed shafts 723 and 733 of the storage section 7 have the same configuration, so their explanation will be omitted. The holding portion and fixed shaft of the front frame 2A can also be removed using the same procedure. To remove the holding portion of the front frame 2A, it is sufficient to open the opening / closing door 4; there is no need to remove the opening / closing door 4.

[0115] To attach the storage unit 7 to the frame 2, simply reverse the above-described procedure. As shown in FIG. 23 , after the fixed shaft 713 of the storage unit 7 is installed in the main body 211 of the frame 2, the holding portion 212 is fixed to the main body 211 with screws, thereby engaging and joining the storage unit 7 to the hollow portion H2 of the frame 2. The holding portions 222 and 232 of the frame 2, the fixed shafts 723 and 733 of the storage unit 7, and the front frame 2A have the same configuration, so their explanation will be omitted. Finally, the rear cover 5 is fixed to the rear frame 2B with screws, completing the storage unit 7 replacement procedure.

[0116] With this configuration, even an end user can easily replace the storage unit 7 using only a screwdriver. Since repairs by an installer or retailer are not required, the usability and convenience of the delivery box 1 can be improved.

[0117] Furthermore, in this embodiment, a foldable delivery box has been described, but the type of delivery box is not limited to this. For example, a delivery box that is installed without folding may also be used. In that case, as described above, even in a delivery box that is installed without folding, the storage section 7 can be configured to be replaceable.

[0118] Furthermore, the present disclosure is not limited to the above-described embodiments, and can be modified as appropriate.

[0119] For example, the size of the delivery box 1 of the present disclosure is not limited to this. Because the frame body 2, connecting portion 3, etc. are made of shaped materials obtained by extruding metal such as aluminum, the size of the delivery box 1 can be freely changed. Because the storage section 7 is made of fabric, there are no size restrictions, and the size of sheet metal members such as the opening and closing door 4 and rear cover 5 can also be easily changed. The size of the delivery box 1 can be flexibly changed to suit the installation location, etc.

[0120] Furthermore, delivery box 1 does not have to be operated using handle portion 31A. If the delivery box has connecting portion 3, opening and closing operations do not have to be performed using a handle, and delivery box 1 may also be shaped without a handle. For example, delivery box 1 can be installed by incorporating it into a gatepost or gate sleeve. In this case, instead of pushing and pulling the handle, for example, a push-open door may be provided, and a mechanism may be used in which storage section 7 pops out when the door is pushed.

[0121] The shape of the frame body 2 and the first link member 31 does not have to have a tapered surface, and may be, for example, a rectangular cylindrical shape. The corners of each component of the frame body 2 and the first link member 31 do not have to be rounded or may not be chamfered.

[0122] Furthermore, the front frame 2A and the rear frame 2B may not be provided with the magnet 8. For example, they may be provided with a connecting mechanism in place of the magnet 8, such as a connecting metal fitting that connects the front frame 2A and the rear frame 2B, or they may not be provided with a connecting mechanism at all.

[0123] The storage section 7 may be configured so as not to be detachable from the frame body 2. For example, the frame body 2 and the storage section 7 may be configured as one unit. In addition, in this embodiment, a gap Z is provided between the rear panel 51 of the rear cover 5 and the wall portion 62 of the base member 6, and an exhaust duct is formed to exhaust air when the storage section 7 is folded, but an exhaust duct need not be provided.

[0124] Furthermore, the delivery box 1 does not necessarily have to include the base member 6. The box main body 10 does not necessarily have to be fixed to the floor surface via the base member 6, but rather the rear frame 2B may be adhesively fixed to the floor surface, for example.
