Summary of the Invention

Problems to be Solved by the Invention

[0004] The security door described in Document 1 enables a home delivery parcel to be received without opening the door when the resident is at home. For example, when the resident is absent and uses leave-at-door delivery, it is necessary to keep the opening open to receive the home delivery parcel with the home delivery parcel receiver with a mailbox. However, since the resident is absent, the opening cannot be closed with the outer plate. Therefore, with the configuration of Document 1, it was not possible to prevent theft when using leave-at-door delivery.

[0005] The present disclosure has been completed based on the above circumstances, and an object thereof is to provide a home delivery receiver that can prevent theft even when using leave-at-door delivery. [Means for solving the problem]

[Modes for carrying out the invention]

[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. The delivery box in this disclosure is (1) A partition separating the outside from the inside, The aforementioned partition has an opening that penetrates from the outside to the inside, An outer flip section that opens and closes the aforementioned opening, An external hinge that rotatably connects the aforementioned external flip portion to the partition, An inner flip section is positioned on the interior side of the outer flip section and opens and closes the opening, The inner flip portion is rotatably connected to the partition by an inner hinge, The outer flip portion can be displaced from a closed state that closes the opening to an open state that moves into the interior and opens the opening by rotation with the outer hinge as the pivot point. The inner flip section can be displaced from an upright state covering the opening to a collapsed state that falls inward towards the interior by rotation with the inner hinge as the pivot point, and has a luggage support surface for placing luggage in the collapsed state. According to the configuration described in (1) above, the delivery person can use the package to push open the outer flip-out section inwards and place the package on the package support surface, thus simplifying the delivery process. Also, if the resident is at home, they can receive the package without having to go outside. If the resident is absent and the package is left at the door, the delivery person can, for example, place the package on the package support surface and then return the outer flip-out section to the closed position to prevent theft.

[0010] (2) In the home delivery receiver according to (1) above, the outer hinge has a biasing portion that biases the outer flip portion to a closed state, and the partition preferably has a stopper that suppresses the opening of the outer flip portion in the closed state to the outdoor side. The open outer flip portion is automatically closed by the biasing portion. The outer flip portion can only open toward the indoor side by the stopper. Therefore, according to the configuration of (2) above, for example, when using door-to-door delivery, even if the outer flip portion is pushed open to the indoor side, it will automatically return to the closed state, and the opening can be maintained in a closed state except when putting luggage into the indoor side.

[0011] (3) In the home delivery receiver according to (2) above, the outer flip portion is preferably disposed at a position where it interferes with the inner flip portion in a standing state during the process of displacement from the closed state to the open state. According to the configuration of (3) above, for example, when a delivery person pushes open the outer flip portion, the standing inner flip portion can be displaced to a lying state. As a result, the inner flip portion can naturally displace to a lying state during the process of receiving luggage, which is convenient.

[0012] (4) In the home delivery receiver according to (3) above, the luggage support surface is preferably inclined downward such that it extends deeper into the indoor side in a lying state. According to the configuration of (4) above, the luggage placed on the luggage support surface moves deeper into the indoor side and moves away from the opening. Even if the outer flip portion is pushed open to the indoor side again after the delivery of the luggage, it becomes difficult to take out the luggage to the outdoor side through the opening. Therefore, it is possible to effectively prevent the theft of luggage.

[0013] (5) In the home delivery receiver according to (3) above, the luggage support surface is preferably disposed horizontally in a lying state. According to the configuration of (5) above, the luggage on the luggage support surface can maintain a horizontally disposed state. For example, even when the luggage is food or fragile items, it is possible to prevent the contents of the luggage from collapsing.

[0014] (6) In the delivery box described in (3) above, it is preferable that the inner flip portion has a stopper portion that protrudes upward from the fallen package support surface and stops the package from entering the room through the opening. According to the configuration described in (6) above, the load can be held in place by the stopper, so the load can be reliably supported on the load support surface.

[0015] (7) In the delivery box described in any of (1) to (6) above, it is preferable that the outer flip section is a double-door type that opens in pairs in the left and right directions. For example, if the outer flip-up section opens to one side, after pushing open the outer flip-up section to bring luggage inside, it is necessary to place the luggage deep inside the room to avoid interference with the outer flip-up section in order to close the outer flip-up section again. This results in a larger inner flip-up section. In contrast, with the configuration of (7) above, the length that the outer flip-up section extends into the room when opened to the room is shorter than in the case of a single flip-up section, so the inner flip-up section can be made smaller.

[0016] [Details of the embodiments of this disclosure] Specific examples of embodiments of this disclosure will be described below with reference to the drawings. However, the present invention is not limited to these examples and is intended to include all modifications within the meaning and scope equivalent to the claims as defined by the claims.

[0017] [Embodiment 1] (Structure of the delivery box 10) The delivery box 10 according to Embodiment 1 of this disclosure includes a door 11 (partition) separating the interior and exterior, an opening 12 penetrating the door 11 from the exterior to the interior, an exterior flip section 13 for opening and closing the opening 12, an exterior hinge 14 rotatably connecting the exterior flip section 13 to the door 11, an interior flip section 15 positioned on the interior side of the exterior flip section 13 for opening and closing the opening 12, and an interior hinge 16 rotatably connecting the interior flip section 15 to the door 11. For the vertical and horizontal directions, the orientations shown in Figure 1 are considered as upward, downward, left, and right, respectively. For the front-to-back directions, the exterior side is considered the rear, and the interior side is considered the front.

[0018] Door 11 is installed at the entrance. As shown in Figure 1, door 11 is positioned with its panel facing forward and backward. A handle 17 and a lock 18 are provided on the right-hand side of the door 11 in the middle of its vertical direction. The entrance is opened when the lock 18 of door 11 is opened and the handle 17 is pulled outwards.

[0019] The opening 12 is formed below the middle of the door 11 in the vertical direction. In this embodiment 1, the opening 12 is positioned below the handle 17 and the lock 18. As shown in Figure 3, the outer flip portion 13 is located inside the opening 12. The opening 12 has a rectangular shape that is larger in the left-right direction than in the up-down direction when viewed from the front-rear direction. The internal structure of the door 11 has been simplified for the sake of drawing.

[0020] As shown in Figure 1, the outer flip sections 13 are paired in the left-right direction. The pair of outer flip sections 13 are flat plates with their surfaces facing in the front-to-back direction. The pair of outer flip sections 13 are double doors that open inwards.

[0021] As shown in Figure 2, the left and right outer ends of each outer flip section 13 are connected to the door 11 by an outer hinge 14. The outer flip section 13 can be displaced from a closed state that closes the opening 12 to an open state that moves inward and opens the opening 12, using the outer hinge 14 as a pivot point.

[0022] The gap formed between the opening 12 and the outer flip portion 13 is sealed with a rubber material (not shown). This prevents rainwater, dust, and other particles from entering the interior through this gap. In other embodiments, it is sufficient that the gap between the opening 12 and the outer flip portion 13 is filled, and the material does not necessarily have to be rubber.

[0023] As shown in Figures 1 and 2, a pillar portion 19 is provided at the left end of the right outer flip portion 13. The pillar portion 19 protrudes forward from the interior-side panel surface of the outer flip portion 13 and projects to the left. In the closed state of each outer flip portion 13, the pillar portion 19 faces the interior-side panel surface of the left outer flip portion 13 so as to be in contact with it. The pillar portion 19 is formed along the entire vertical length of the left outer flip portion 13. In this embodiment 1, the left-right inner ends of each outer flip portion 13, excluding the pillar portion 19, face each other at the left-right intermediate portion of the opening 12.

[0024] The outer hinge 14 is connected to the interior side panel of the door 11. In this embodiment 1, the outer hinge 14 is a spring hinge. The outer hinge 14 has a spring-shaped biasing part 20 that biases the outer flip portion 13 to the closed position. After the outer flip portion 13, which is in the closed position, is pressed from the outside and displaced to the open position, the outer flip portion 13 returns to the closed position when the biasing force of the biasing part 20 exceeds the external force from the outside. In this embodiment 1, the outer hinge 14 sets the maximum opening angle of the open outer flip portion 13 relative to the door 11 to 90 degrees.

[0025] As shown in Figure 3, the door 11 has an opening stopper 21 that prevents the outer flip portion 13 from opening outwards when it is in the closed position. The opening stopper 21 protrudes from both the upper and lower edges inside the opening 12. The opening stopper 21 is positioned to be able to contact the upper and lower ends of the outer flip portion 13 from the outside.

[0026] As shown in Figures 2 and 3, the inner flip section 15 has a flat plate shape that is larger in the vertical and horizontal directions than the outer flip section 13. The lower end of the inner flip section 15 is connected to the door 11 by an inner hinge 16. The inner flip section 15 can be displaced from an upright state that covers the opening 12 from the interior side to a collapsed state that falls inward, using the inner hinge 16 as a pivot point. In the upright state, the inner flip section 15 covers the opening 12, the outer flip section 13, and the outer hinge 14 from the interior side. In addition, the upright inner flip section 15 is positioned to interfere with the outer flip section 13 in the process of displacing from the closed state to the open state.

[0027] The inner flip section 15 has a luggage support surface 22 as its upper surface when it is in the collapsed state. As shown in Figure 6, in this embodiment 1, the luggage support surface 22 is positioned horizontally when it is in the collapsed state. The luggage support surface 22 is a surface on which luggage 50 can be placed. When it is in the upright state, the luggage support surface 22 faces the interior side panel of the door 11.

[0028] The front end of the inner flip section 15 is provided with a stopper section 28 that protrudes upward from the cargo support surface 22 when the unit is in a collapsed state. The stopper section 28 is formed across the entire width of the inner flip section 15 in the left-right direction. The stopper section 28 functions as a stopper when the cargo 50 is placed on the cargo support surface 22.

[0029] As shown in Figure 3, the lower end of the inner flip portion 15 has a shaft portion 23 that protrudes from both the left and right ends, and an overhang portion 24 that extends forward from the shaft portion 23. The shaft portion 23 is cylindrical and fits into a recess 26 of the inner hinge 16, which will be described later. The overhang portion 24 has a fan-shaped cross-section. The lower end surface and rear end surface of the overhang portion 24 in Figure 3 are flat surfaces without steps.

[0030] As shown in Figure 3, the internal hinge 16 has a base end portion 25 attached to the door 11, a thin-walled portion 27 formed in front of the base end portion 25, and a recess 26 that extends inward in the left-right direction across the base end portion 25 and the thin-walled portion 27. The front end surface of the base end portion 25 is a flat surface along the vertical direction. The thin-walled portion 27 has a semicircular cross-section and is formed recessed in the left-right direction from the base end portion 25. The recess 26 is circular in side view. The shaft portion 23 of the internal flip portion 15 rotatably fits into the recess 26. When the internal flip portion 15 is displaced from an upright state to a collapsed state, the shaft portion 23 rotates within the recess 26. At this time, the protruding portion 24 rotates within the thin-walled portion 27. When the lower end surface of the protruding portion 24 contacts the front end surface of the base end portion 25, the rotation of the internal flip portion 15 stops. As a result, the internal flip portion 15 collapses.

[0031] As shown in Figures 2 and 3, the door 11 has a locking part 29 that can be engaged with the upper end of the upright inner flip portion 15. The locking part 29 is provided on the upper edge of the opening 12 on the interior side. The locking part 29 is rotatable along the surface of the door 11. The locking part 29 engages with (locks) the upper end of the inner flip portion 15, thereby maintaining the inner flip portion 15 in an upright position. In this state, even if the outer flip portion 13 is pressed from the exterior side, the upright inner flip portion 15 prevents it from opening inward, causing the opening 12 to open slightly from the closed state or remain closed.

[0032] (The function of the delivery box 10) Next, the operation of the delivery box 10 of this embodiment 1 will be described. For example, if there is no scheduled delivery of a delivery person, the inner flip section 15 is raised and locked with the lock section 29. When the delivery box 10 is not in use, the inner flip section 15 is raised to prevent it from obstructing the opening and closing of the door 11. In addition, even if the outer flip section 13 in the closed state is pressed from the outside, the locked, raised inner flip section 15 prevents the outer flip section 13 from opening inwards. Therefore, when a package 50 is not to be received, the opening 12 can be kept closed.

[0033] For example, if a delivery person is scheduled to visit, the lock on the inner flip portion 15 of the lock portion 29 is released. As shown in Figures 4 and 5, the package 50, supported by the delivery person's hand 51, pushes the outer flip portion 13 open towards the interior. At this time, the closed outer flip portion 13 interferes with the upright inner flip portion 15 as it displaces to the open position. The upright inner flip portion 15 falls inward and displaces to a fallen position. The package 50 is placed on the package support surface 22 and further enters the interior. As shown in Figure 5, the package 50 can enter the interior until it is stopped by the stopper portion 28. As shown in Figure 6, the open outer flip portion 13 returns to the closed position by the biasing portion 20 and the delivery is completed. Since the opening 12 is closed by the outer flip portion 13, the package 50 is not visible from the outside.

[0034] As described above, the delivery box 10 of this embodiment 1 includes a door 11 (partition) separating the outside and the inside, an opening 12 that penetrates the door 11 from the outside to the inside, an outer flip section 13 that opens and closes the opening 12, an outer hinge 14 that rotatably connects the outer flip section 13 to the door 11, an inner flip section 15 positioned on the interior side of the outer flip section 13 that opens and closes the opening 12, and an inner hinge 16 that rotatably connects the inner flip section 15 to the door 11. The outer flip section 13 can be displaced from a closed state that closes the opening 12 to an open state that moves into the interior and opens the opening 12 by rotating with the outer hinge 14 as the pivot point. The inner flip section 15 can be displaced from an upright state that covers the opening 12 to a collapsed state that falls inward towards the interior by rotating with the inner hinge 16 as the pivot point. In the collapsed state, it has a luggage support surface 22 on which luggage 50 is placed. According to this, for example, a delivery person can use the package 50 to push open the outer flip section 13 inward and place the package 50 on the package support surface 22 through the opening 12. Even if both hands are occupied with the package 50, the package 50 can be easily placed on the package support surface 22, simplifying the delivery process. Also, for example, if the resident is at home, they can receive the package 50 without going outside. For example, if the resident is absent and the service is to leave the package at the door, the package 50 is placed on the inside, so the package 50 is not left unattended outside. After the delivery person places the package 50 on the package support surface 22, the opening 12 is closed by returning the outer flip section 13 to its closed state. Therefore, the delivery receiver 10 can help prevent theft of the package 50 even when the service is to leave the package at the door.

[0035] The outer hinge 14 has a biasing part 20 that biases the outer flip section 13 to a closed position. The door 11 (partition) has an opening stopper 21 that prevents the outer flip section 13 from opening outwards when it is closed. As a result, the outer flip section 13 automatically closes when it is closed due to the biasing part 20. The outer flip section 13 opens only inwards due to the opening stopper 21. Therefore, even if the outer flip section 13 is pushed open inwards when a package 50 is delivered, it automatically returns to the closed position, and the opening 12 can be kept closed except when the package 50 is being brought inside.

[0036] The outer flip section 13 is positioned to interfere with the inner flip section 15, which is in an upright position, during the process of displacement from a closed state to an open state. This allows the inner flip section 15, which is in an upright position, to be displaced to a folded state by pushing open the outer flip section 13 in a closed state. This is convenient because it can be displaced to a folded state naturally during the process of receiving the package 50.

[0037] The cargo support surface 22 is positioned horizontally when the structure is in a collapsed state. This allows the cargo 50 on the cargo support surface 22 to maintain a horizontal position. For example, even if the cargo contains food or fragile items, this prevents the contents of the cargo from collapsing.

[0038] The inner flip portion 15 protrudes upward from the inverted cargo support surface 22 and has a stopper portion 28 that prevents the cargo 50 from entering the room through the opening 12. This ensures that the cargo 50 is securely supported on the cargo support surface 22.

[0039] The outer flip section 13 is a double-door type, with a pair of sections opening in the left-right direction. This reduces the length of the outer flip section 13 that enters the room when it opens inward, compared to the case where the outer flip section is a single-door type in other embodiments. As a result, the inner flip section 15 can be made smaller.

[0040] The outer flip section 13 is set to open up to 90 degrees relative to the door 11 when in the open position. This allows the luggage 50 to be pushed into the room while each outer flip section 13 contacts the side of the luggage 50. Therefore, it is easy to push the luggage 50 straight into the room.

[0041] [Embodiment 2] As shown in Figure 7, the shape of the inner flip portion 15A of the delivery box 10A in Embodiment 2 differs from that of Embodiment 1. In addition, a mesh portion 30 is attached to the inner flip portion 15A. The other parts are the same as in Embodiment 1.

[0042] As shown in Figure 7, the inner flip section 15A has a straight section 31 extending straight from the inner hinge 16, a locked section 32 that engages with the lock section 29, and a bent section 33 that bends and connects the straight section 31 and the locked section 32. In the upright position, the straight section 31 is inclined forward from the inner hinge 16 to the bent section 33. As a result, as shown in Figure 8, the cargo support surface 22A, which is the upper surface of the straight section 31 in the collapsed position, is inclined downward as it goes deeper into the interior.

[0043] As shown in Figure 8, in the collapsed state, the bent portion 33 bends upward from the front end of the straight portion 31. The bent portion 33 can stop the luggage 50, just like the stopper portion 28 in Embodiment 1. The locking portion 32 protrudes forward from the upper end of the bent portion 33. As shown in Figure 7, in the upright state, the locking portion 32 is positioned along the door 11.

[0044] The delivery box 10 of Embodiment 2 has a mesh-like mesh section 30. For example, the mesh section 30 is made of wire mesh. The mesh section 30 is connected to the inner flip section 15A and the door 11. With respect to the inner flip section 15A, it is connected to the upper end of the bent section 33 and both left and right ends of the straight section 31. Specifically, the mesh section 30 is held in place by being sandwiched between metal plates or the like (not shown). The metal plates are screwed to the upper end of the bent section 33 and both left and right ends of the straight section 31. With respect to the door 11, it is connected to the opening edge of the opening 12, excluding the lower edge of the opening. Similar to the inner flip section 15A, it is screwed to the opening edge of the opening 12, excluding the lower edge of the opening, via the metal plates. The mesh section 30 is provided with a zipper-like retrieval section 34 that can be opened and closed from the inside. By opening the retrieval section 34, the package 50 can be retrieved. Note that the retrieval section 34 cannot be opened from inside the mesh section 30. In the upright position, the mesh section 30 is stored between the straight section 31 and the bent section 33 and the outer flip section 13, and in the reclined position, it spreads out between the door 11 and the inner flip section 15A. This prevents the luggage 50 from falling, even if, for example, luggage 50 entering through the opening 12 shifts laterally from the luggage support surface 22A.

[0045] As described above, the luggage support surface 22A of Embodiment 2 is inclined downward so that it extends deeply into the interior when in a collapsed state. As a result, as shown in Figure 8, simply placing the luggage 50 on the luggage support surface 22A causes the luggage 50 to move deep into the interior. For example, even if the outer flip section 13 is pushed open again in the interior after the luggage 50 has been delivered, it becomes difficult to retrieve the luggage 50 from the outside.
