Description

[Technical Field]

[0001] The present disclosure relates to receiving boxes. [Background technology]

[0002] Conventionally, there has been known a structure in which a delivery box is installed on the exterior wall of a building, a wall such as a fence, or a pillar such as a gatepost, allowing delivery items to be received even when the recipient is not at home (see Patent Document 1). On the other hand, a post box for receiving mail that has been posted is generally installed near the entrance of a building. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6527475 Summary of the Invention [Problem to be solved by the invention]

[0004] If the delivery box and mailbox are installed separately on a wall, pillar, or nearby, the number of parts increases and the installation process becomes more tedious. Furthermore, after a package is deposited in the delivery box and the front door is locked, the recipient may open the rear door to retrieve the package. In this case, after retrieving the package, the recipient must move to the front door and unlock it with a key or other device to be able to retrieve another package, which makes the unlocking process more tedious.

[0005] The object of the present disclosure is to provide a receiving box that can receive parcels and postal items while reducing the number of parts and facilitating installation, and that makes it easy for the recipient to unlock the box. [Means for solving the problem]

[0006] A receiving box according to one aspect of the present disclosure is a receiving box that functions as both a post box and a delivery box, and includes a mail storage chamber in which mail can be stored, at least one delivery storage chamber in which delivery items can be stored, a mail slot for a post provided on the front of the mail storage chamber, at least one storage door for storing delivery items provided on the front of the delivery storage chamber, a removal door provided on the rear side, and a box body to which the storage door and removal door are attached so as to be openable and closable, wherein the storage door includes a lockable storage door locking unit, and a link mechanism provided between the removal door and the storage door locking unit unlocks the storage door locking unit when the removal door is opened. [Effects of the Invention]

[0007] According to one embodiment of the receiving box of the present disclosure, it is possible to receive parcels and mail while reducing the number of parts and simplifying installation, and it is also possible to make it easier for the recipient to unlock the box.

[0009] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. The shapes, materials, and quantities described below are examples for the purpose of explanation and can be changed as appropriate depending on the specifications of the receiving box. In the following, the same elements will be denoted by the same reference numerals in all drawings.

[0010] A receiving box 1 according to an embodiment will be described with reference to Figures 1 to 32. Figures 1 and 2 are perspective views of the receiving box 1 as viewed from the front side, with Figure 1 showing a state in which the upper door 14 and the lower door 16 are closed, and Figure 2 showing a state in which the upper door 14 and the lower door 16 are open. Figure 3 is an enlarged perspective view showing the inner surfaces of the upper door 14 and the lower door 16 in Figure 2. Figure 4 is a view of a flap assembly provided in the mail slot shown in Figure 3 as viewed from the front side. Figure 5 is a perspective view of the receiving box 1 as viewed from the rear side with the removal door 18 closed. Figure 6 is a perspective view of the receiving box 1 as viewed from the rear side with the removal door 18 open. Figure 7 is a partially enlarged perspective view of the removal door 18 shown in Figure 6.

[0011] In the following description, the side of the receiving box 1 where the outer door 12 is located is referred to as the front side or front side, and the opposite side is referred to as the back side or rear side, with left and right basically defined as the left and right sides when viewed from the front side of the receiving box 1. Also, in the following description and drawings, the direction connecting the front and rear sides may be referred to as the front-to-rear direction. R is the right side when viewed from the front side of the receiving box 1, L is the left side, F is the front side of the receiving box 1, and B is the rear side of the receiving box 1. The direction connecting R and L and the direction connecting F and B are perpendicular to each other. In the following description, the left and right arrangement relationship may be reversed.

[0012] The receiving box 1 is for a detached house and is a wall-mounted type that is attached to a wall 100 provided near the entrance to a fence or the like that separates the inside and outside of the house's premises. A panel 102 with an intercom is attached to the upper side of the wall 100. Note that the receiving box 1 is not limited to being used in this mounted state, and may be a wall-mounted type that is attached to an exterior wall that separates the inside and outside of the house, an assembled type that is attached to a gatepost, or a stationary type that is placed near the front door or next to a gatepost or fence.

[0013] The receiving box 1 can receive parcels (not shown), which are parcels to be delivered, without any staff present. Parcels are deposited in the receiving box 1 by a parcel delivery person, and doors closing the front and back sides of the parcel storage room 21 in which the parcels are stored are locked. The recipient of the parcel can retrieve the parcel from the back side of the receiving box 1. This allows the receiving box 1 to function as a parcel box.

[0014] The receiving box 1 includes a rectangular parallelepiped box body 10, a mail slot 19, an upper door 14 and a lower door 16 attached to the box body 10 so as to be able to open and close, and a removal door 18 (FIG. 5).

[0015] Box body 10 is formed by assembling top panel 10a at the upper end, left panel 10b, right panel 10c, and bottom panel 10d at the lower end into a rectangular box shape, and has front opening 10e at the front end and rear opening 10f at the rear end. As shown in Figures 3 and 6, the interior space of box body 10 is divided into three upper and lower spaces by an upper partition panel 24 fixed to box body 10 and a movable shelf panel 25 below partition panel 24. The upper space inside receiving box 1 is mail storage chamber 20 in which mail can be stored. The middle space inside receiving box 1 is upper storage chamber 22 of delivery item storage chamber 21, and the lower space is lower storage chamber 23 of delivery item storage chamber 21. Delivery items can be stored in upper and lower storage chambers 22 and 23.

[0016] A post wall 26 is provided at the front end of the mail storage chamber 20. A long, horizontal mail slot 19 for mail is provided on the post wall 26. A flap assembly 28 (Figure 4), which will be described later, is provided on the rear side of the post wall 26. Note that the flap assembly 28 is not shown in the drawings showing the mail slot 19 other than Figure 4. A mail carrier posts mail into the mail storage chamber 20 through the mail slot 19 and the insertion opening 28a of the flap assembly 28. A mail recipient can retrieve the mail from the rear side of the receiving box 1. This allows the receiving box 1 to also function as a post box.

[0017] The upper door 14 is a storage door for storing parcels, and is provided on the front surface of the upper storage chamber 22, closing the front side of the upper storage chamber 22. The lower door 16 is also a storage door, and is provided on the front surface of the lower storage chamber 23, closing the front side of the lower storage chamber 23. The upper door 14 and the lower door 16 are rotatably supported on the box body 10 by hinges attached to the L-side end of the front side edge of the box body 10. This allows the upper door 14 and the lower door 16 to be attached to the box body 10 so as to be able to open and close. An upper storage door locking unit 32 (Fig. 3) that can lock the upper door 14 is attached to the upper door 14. A lower storage door locking unit 33 (Fig. 3) that can lock the lower door 16 is attached to the lower door 16.

[0018] An outer door 12 is provided at the front side edge of the receiving box 1, outside the post wall 26, upper door 14, and lower door 16. The outer door 12 is rotatably supported on the box body 10 by a hinge attached to the L-side edge of the front side edge of the box body 10. This allows the outer door 12 to be attached to the box body 10 so that it can be opened and closed. The outer door 12 is not provided with a locking function, so the user can open and close it freely.

[0019] As shown in Figures 5 to 7, a removal door 18 is provided at the rear end of the receiving box 1. The removal door 18 is rotatably supported on the box body 10 by a hinge attached to the L-side end of the rear end of the box body 10. This allows the removal door 18 to be attached to the box body 10 so that it can be opened and closed. A removal door lock unit 34, which will be described later, is provided on the removal door 18. The removal door lock unit 34 can lock the removal door 18, and can be unlocked by pressing an unlock button 51, which has a set number, to input a personal identification number.

[0020] As shown in Figure 4, a flap set 28 having two sets of flaps 29 that can rotate up and down is supported around the mail slot 19 on the back side of the post wall 26. Each flap 29 has multiple flap plates 30 that are rotatably supported on flap shafts (not shown) that extend horizontally at both the top and bottom ends of the flap set 28, and each flap plate 30 is biased by a biasing member such as a spring in a direction that narrows the vertical length of the insertion opening 28a between the two flaps 29. With the outer door 12 open, a mail carrier can rotate each flap 29 of the flap set 28 to widen the insertion opening 28a between the flaps 29 and then insert mail into the mail storage chamber 20 through the mail slot 19.

[0021] In addition, a magnet may be attached to the end of the outer door 12 opposite to the hinge attachment side, and the magnet may be made to be able to be attracted to the box body 10 made of a metal such as iron, or to a metal bracket fixed to the box body 10, thereby making it easier to keep the outer door 12 closed.

[0022] Next, the movable shelf 25 and its mounting structure will be described with reference to Figures 8 to 12. Figure 8 is a perspective view of the inside of the receiving box 1 with the access door 18 removed from the state shown in Figure 6. Figure 9 is a perspective view of the receiving box 1 with the hanging end of the movable shelf 25 enlarged and viewed from the rear. Figure 10 is a view of Figure 9 with the movable shelf removed. Figure 11 is a perspective view of the end of the movable shelf 25 on the engagement portion 36 side, viewed from above. Figure 12 is a perspective view of the delivery item storage chamber 21 with the movable shelf removed and the inner surface on the receiving portion 41 side enlarged and viewed from the rear.

[0023] As shown in Fig. 8, movable shelf 25 is provided inside delivery item storage compartment 21, below partition plate 24. Movable shelf 25 is supported by box body 10 so as to be rotatable about a pin provided at the L-side end of box body 10. Specifically, as shown in Figs. 8 and 9, movable shelf 25 is box-shaped and has a rectangular top plate 25a and a peripheral wall portion 25b extending downward from the outer peripheral edge of top plate 25a all around.

[0024] As shown in Figure 10, on the inner surface of the box body 10, pin support members 38 are attached at two positions spaced apart in the front-to-rear direction in the vertically central portion of the inner surface of the left side plate 10b, to which the hanging end of the movable shelf 25 is attached. Each pin support member 38 has a fixed plate portion (not shown) fixed to the inner surface of the left side plate 10b and a pair of protruding plate portions 39 extending from both front-to-rear ends of the fixed plate portion toward the inside of the delivery item storage compartment 21, and a pin 42 is supported between the lower ends of the protruding plate portions 39 so as to extend in the front-to-rear direction. A portion of the fixed plate portion is covered by a cover member 43 fixed to the inner surface of the left side plate 10b.

[0025] A cylindrical winding portion 45 provided at one end of a metal rotating plate member 44 is fitted around each pin 42. Furthermore, a flat plate portion 46 connected to the winding portion 45 of the rotating plate member 44 is fixed with screws to the outer surface of the wall portion forming the L-side end of the peripheral wall portion 25b of the movable shelf 25. This allows the movable shelf 25 to be supported by the box body 10 and to rotate around the pin 42 provided at the L-side end of the box body 10.

[0026] When the R-side end of the peripheral wall 25b of the movable shelf 25 is not fixed to the box body 10, the movable shelf 25 pivots downward along the left side panel 10b, as shown by the two-dot chain line in Figure 6. In this case, the delivery storage compartment 21 is not divided by the movable shelf 25, so the receiving box 1 can receive large parcels that do not fit into either the upper storage compartment 22 or the lower storage compartment 23.

[0027] Furthermore, as shown in FIG. 11 , a handle member 35 that engages with a member on the right side panel 10c is supported on the R-side end of the movable shelf 25. Specifically, a fixed plate 25h having a rectangular cross-sectional recess in the middle in the front-to-rear direction is fixed to the underside of the R-side end of the movable shelf 25. The handle member 35 is supported on the upper surface of the bottom plate of the recess of the fixed plate 25h so as to be movable in the left-to-right direction. The handle member 35 has an engaging portion 36 and a handle 37. The handle member is box-shaped with an opening at the bottom end, and the engaging portion 36 is provided on the R-side end. The handle 37 is a rectangular opening that is large enough to fit a person's fingers and penetrates in the vertical direction and is provided in the middle of the top panel 35a of the handle member 35.

[0028] Furthermore, the handle member 35 is biased toward the R side of the movable shelf 25 by locking portions (not shown) protruding from both front-rear side surfaces of the handle member 35 and an engaging portion biasing member (not shown), such as a spring, provided between the fixed plate 25h and the handle member 35. As a result, the engaging portion 36 of the handle member 35 protrudes from a rectangular opening 25c provided at the R end of the peripheral wall portion 25b of the movable shelf 25. Also, a rectangular opening 25d larger than the handle 37 of the handle member 35 is formed in the top plate 25a of the movable shelf 25 at a position opposite the handle 37 of the handle member 35. This allows a user to insert their hand into the handle 37 from above through the opening 25d and retract the engaging portion 36 of the handle member 35 toward the inside of the movable shelf 25 against the biasing force of the engaging biasing member. Therefore, the handle 37 of the handle member 35 is interlocked with the engagement portion 36 that can protrude and retract from the side surface of the movable shelf board 25 .

[0029] As shown in Figure 12, a receiving member 40 formed into a rectangular tube shape by bending a metal plate or the like is fixed to the inner surface of the middle portion in the vertical direction of the right side plate 10c of the box body 10. The receiving member 40 extends in the front-to-rear direction. A receiving portion 41, which is a rectangular opening, is formed in the plate portion at the L-side end of the receiving member 40. An engaging portion 36 (Figure 11) protruding from the side of the movable shelf 25 engages with the receiving portion 41. This fixes the movable shelf 25 to the box body 10 and keeps it horizontal. In this state, the inside of the delivery item storage compartment 21 is divided into upper and lower sections by the movable shelf 25.

[0030] On the other hand, when the user retracts the engaging portion 36 of the handle member 35 to the inside of the movable shelf board 25, the engaging portion 36 is disengaged from the receiving portion 41. This allows the movable shelf board 25 to be pivoted downward.

[0031] Returning to Figure 3, a protrusion 48 is provided at the upper end of the inner surface of lower door 16, for example, by fixing an L-shaped cross-section plate member 49. When lower door 16 is closed, protrusion 48 engages with the lower end of movable shelf 25, preventing movable shelf 25 from moving downward. As a result, movable shelf 25 does not move downward when lower door 16 is closed, so even if lower door 16 is locked and upper door 14 is unlocked, it is not possible to push down movable shelf 25 from upper storage compartment 22 and remove items stored in lower storage compartment 23 after upper door 14 is opened. This improves security.

[0032] Figure 13 is an enlarged perspective view of the operating unit 50 of the removal door lock unit 34 shown in Figure 5, viewed from the rear side. As shown in Figure 5, the operating unit 50 of the removal door lock unit 34 is exposed on the outer surface of the removal door 18 through a horizontally long opening 18a. Referring to Figure 7, the removal door lock unit 34 has a rectangular cylindrical case 53 that is long in the horizontal direction, and a latch unit 54 that is housed in the case 53 and can protrude and retract from the front end side of the door, and is attached to the inside of the removal door 18 via a cover 55. The latch unit 54 is engageable with a latch receiver 56 (Figure 8) fixed to the rear end of the box body 10.

[0033] The latch receiver may be a protruding plate portion 10g (FIG. 8) itself that protrudes to the L side by bending the rear end of the right side plate 10c of the box body 10. The latch portion 54 is biased in the direction of protruding from the case 53, which is the locking side, by a biasing member such as a spring provided inside the case 53. The access door lock portion 34 shown in FIG. 13 is a mechanical push lock that prevents the latch portion 54 from retracting to the unlocked position when the latch portion 54 protrudes from the case 53. The access door lock portion 34 does not require a power source such as a battery.

[0034] Furthermore, the operation unit 50 of the removal door lock unit 34 has a plurality of unlock buttons 51, each of which is numbered and can be moved in a pushing direction, and a knob unit 52. The operation unit 50 is used to retract the latch unit 54 into the case 53 to unlock the door.

[0035] The knob 52 is connected to the latch 54, and by sliding the knob 52 toward the L side, which is the side of the left side panel 10b, the latch 54 can be moved from the locked position to the unlocked position. The sliding operation of the knob 52 is regulated by a plurality of unlock buttons 51.

[0036] Of the multiple unlock buttons 51, by pressing all of the unlock buttons 51 that make up the PIN as preset setting buttons, the knob portion 52 can be slid to the L side. This allows the latch portion 54 to be moved from the locked position to the unlocked position. On the other hand, if all of the unlock buttons 51 that make up the PIN are not pressed, the knob portion 52 cannot be slid, and the latch portion 54 cannot be moved to the unlocked position.

[0037] Returning to FIG. 7 , the access door lock unit 34 has a setting operation unit 57 for setting the unlock button 51 that constitutes the PIN number from among the multiple unlock buttons 51, and a cover 58. The cover 58 covers the setting operation unit 57. The setting operation unit 57 is provided on the back side of the case 53. The cover 58 is detachably attached to the back side of the case 53 with fasteners such as screws. By removing the cover 58, the setting operation unit 57 can be operated. The unlock button 51 that constitutes the PIN number can be changed by operating the setting operation unit 57.

[0038] Therefore, as shown in FIG. 13 , when the knob 52 is moved to the R side, which is the locked side, the latch 54 protrudes from the case 53 due to the biasing force of the biasing member. When the access door 18 is closed from the open state in this state, the inclined surface of the latch 54 is pressed by the corner of the latch receiver 56, and after being resiliently pushed in, it moves forward of the latch receiver 56 and protrudes and engages with the front side of the latch receiver 56. In this state, even if an attempt is made to slide the knob 52 to the L side, it cannot be slid, preventing the access door 18 from opening and maintaining the locked state. On the other hand, if the recipient presses all of the unlock buttons 51 corresponding to the preset PIN number, the knob 52 can be slid. This causes the latch 54 to retract from the latch receiver 56, allowing the access door 18 to open. In this configuration, no power from a battery or an external commercial power source is required to lock and unlock the removal door 18, eliminating the need to replace batteries, and the need to connect a power line makes it easy to install the luggage receiving box.

[0039] Furthermore, the receiving box 1 is provided with a link mechanism 60 (see FIG. 15, etc.) between the removal door 18 and the storage door locks 32, 33 provided on the upper door 14 and lower door 16. The receiving box 1 is configured such that the storage door locks 32, 33 are unlocked by the link mechanism 60 when the removal door 18 is opened. In this regard, the link mechanism 60 for the lower door 16 will be specifically described below with reference to FIGS. 14 to 32. The link mechanism for the upper door 14 is configured in the same manner as the link mechanism 60.

[0040] Fig. 14 is a perspective view of the receiving box 1 when it is waiting for arrival, with the vertical middle part in the range H in Fig. 1 cut away and some parts omitted, as viewed from above. Fig. 15 is a perspective view of the lower storage door locking part 33, the intermediate link bar 61, and the link cover 62 taken out from Fig. 14.

[0041] As shown in Figures 14 and 15, the lower storage door locking unit 33 is unlocked during package arrival waiting. During package arrival waiting, the receiving box 1 is waiting for a package to be delivered by a delivery person. In this case, the knob 90 of the lower storage door locking unit 33 is moved to the L-side position, which is the unlocked position, and the latch 91 of the lower storage door locking unit 33 is retracted into the case 86. This makes it possible to open the lower door 16 by hooking a part of the front end of the lower door 16 with a finger or the like. Note that a pop-up mechanism that operates to slightly open the lower door 16 using a biasing member such as a spring can be provided between the lower door 16 and the box body 10 when the lower storage door locking unit 33 is in the unlocked state.

[0042] 14, a door lever 104 is fixed to the front surface of the R-side end of the lower door 16. Through a rectangular opening formed in the door lever 104, the front surface of the lower storage door locking portion 33 and the knob portion 90 are exposed on the front surface of the lower door 16.

[0043] Meanwhile, when the access door 18 is closed and locked, the lever receiver 65 provided on the inner surface of the access door 18 pushes the rear link lever 66 (described later) forward. As a result, as described later, the front release lever 67 (FIG. 15) connected to the lever receiver 65 via the intermediate link bar 61 is retracted toward the box body 10. In this state, when the knob 90 moves to the R side, which is the locking side, the knob 90 is prevented from returning to the L side, which is the unlocking side, and the lower storage door lock 33 is locked, as described later.

[0044] Figure 16 is a view corresponding to Figure 15 when the front and rear doors of the receiving box 1 are locked. When a parcel delivery person delivers a parcel in the standby state shown in Figures 14 and 15, the delivery person opens the lower door 16 and places the parcel in the lower storage compartment 23. Then, as shown in Figure 16, the delivery person moves the knob portion 90 to the R-side position, which is the locked position. This causes the latch portion 91 to protrude from the lower door 16 toward the latch receiver provided on the box body 10 and engage with the latch receiver. As shown in Figure 29 described below, the latch receiver 10h is formed by bending the front end of the right side panel 10c of the box body 10, resulting in a protruding portion with a rectangular cross section protruding to the L-side.

[0045] The latch receiver may be a member separate from the box body 10, such as a metal fitting fixed to the front end of the right side panel of the box body 10, or may be a rectangular or other hole formed in the box body 10 or the metal fitting. The latch receiver may be anything that faces the latch portion 91 so as to be engageable with it when the latch portion 91 protrudes toward the latch receiver, and prevents the lower door 16 from opening. When the latch portion 91 is engaged with the latch receiver, the latch portion 91 is prevented from retracting toward the lower door 16 by a locking cam 94 (Figs. 18 to 23) of the lower storage door locking portion 33, which will be described later. Therefore, the lower door 16 remains locked.

[0046] The configuration and operation of the lower storage door locking unit 33 will be described in detail below using Figures 17 to 23, with reference to Figures 15 and 16. Figure 17 is a perspective view of the lower storage door locking unit 33 removed from Figure 15 and viewed from the rear side. Figure 18 is a perspective view of the lower storage door locking unit 33 with the rear cover 87 removed. Figure 19 is a perspective view of the lower storage door locking unit 33 with the intermediate plate 88 omitted from Figure 18. Hereinafter, the lower storage door locking unit 33 may be simply referred to as the storage door locking unit 33.

[0047] The storage door locking unit 33 has a case 86, a latch portion 91 supported on the case 86 so as to be movable in the left-right direction, and a knob portion 90 (FIG. 22) formed integrally with the latch portion 91 and interlocking with the latch portion 91. The latch portion 91 and knob portion 90 are formed on a latch member 85. The storage door locking unit 33 also has a locking cam 94 rotatably supported on the case 86. When the knob portion 90 is moved to the L side, which is the unlocking side, as shown in FIG. 15, the latch portion 91 retracts into the case 86. In this state, the lower door 16 is unlocked or in a waiting state for arrival of goods, and can be opened.

[0048] Figure 20 is a view corresponding to Figure 18 when the storage door locking unit 33 is locked. Figure 21 is a view corresponding to Figure 19 when the storage door locking unit 33 is locked. When the knob 90 is moved to the R side, which is the locking side, as shown in Figure 16, the latch 91 protrudes from the case 86 to the R side. In this state, the latch 91 protrudes toward the latch receiver 10h (Figure 29) provided on the box body 10, locking the lower door 16.

[0049] As shown in Figures 18 to 21, the locking cam 94 has a generally T-shaped shape when viewed from one side in the front-to-rear direction, and restricts the return movement of the knob portion 90 when locked. Furthermore, both upper and lower ends of the locking cam 94 are exposed through openings 86a, 86b (Figure 17) formed at both upper and lower ends of the R-side end of the case 86. This makes it easy to access the locking cam 94 from inside the box body 10, even if a child or the like enters the box body 10 to play or play and the lower door 16 is closed and locked. Therefore, by rotating the locking cam 94 in a direction that does not restrict the movement of the knob portion 90, the storage door lock portion 33 can be easily unlocked and the lower door 16 can be opened.

[0050] Fig. 22 is an exploded perspective view seen from the rear side of the storage door locking portion 33. Fig. 23 is an exploded perspective view seen from the front side of the storage door locking portion 33. The rear cover 87 is not shown in Figs. 22 and 23.

[0051] 17 is formed into a generally box-like shape by butting together a front cover 89 and a rear cover 87 in the front-to-rear direction and screwing them together with an intermediate plate 88 sandwiched between them. As shown in Fig. 22, a guide wall 89a that restricts the movement of the latch member 85 in the left-to-right direction is formed on the rear side of the front cover 89. As shown in Fig. 23, a horizontally long rectangular hole 89b is formed in the center of the front cover 89, and a knob portion 90 (Fig. 22) of the latch member 85 protrudes forward through this hole 89b.

[0052] The latch member 85 has a block shape that is elongated in the left-right direction, and a knob portion 90 protrudes from the front surface. A latch portion 91, which is generally rectangular and can protrude from the case 86, is formed on the R-side portion of the latch member 85 from the knob portion 90. A latch protrusion 92 formed on the rear surface of the L-side end of the latch member 85 engages with a rectangular hole 88a that is elongated in the left-right direction and formed in the intermediate plate 88. This restricts the movement of the latch member 85 in the left-right direction. The latch protrusion 92 is generally rectangular, and its lower surface extends along the left-right direction. A recess 85a formed on the back surface of the latch member 85 houses a biasing member 93, such as a coil spring. Two biasing members 93 are combined, but only one biasing member 93 may be provided. A locking protrusion 88b formed on the front surface of the intermediate plate 88 enters the recess 85a and is pressed against the biasing member 93, biasing the latch member 85 in a direction to retract into the case 86.

[0053] A first support pin 88c and a second support pin 88d are aligned on the left and right and fixed so as to protrude rearward on the back surface of the intermediate plate 88. A locking cam 94 is rotatably supported by the first support pin 88c.

[0054] The locking cam 94 is formed in a generally T-shape, with a first linear portion 95 and a second linear portion 96 that are perpendicular to each other. The first linear portion 95 extends generally in the left-right direction, and the second linear portion 96 extends generally in the up-down direction. A circular hole 94a is formed at the intersection of the first linear portion 95 and the second linear portion 96, and a first support pin 88c is inserted into the hole 94a. This allows the locking cam 94 to be rotatably supported by the case 86.

[0055] A cam biasing member 98, which is a coil spring, is supported on the second support pin 88d so as to be pivotable about the second support pin 88d. Both ends of the cam biasing member 98 are biased in a direction in which they abut against the L-side ends of wall portions 88e, 88f, which protrude rearward from the upper and lower sides of the intermediate plate 88. As shown in FIG. 23 , locking protrusions 94b, 94c are formed on both the upper and lower sides of the front side of the second linear portion 96 of the locking cam 94. The upper end of the cam biasing member 98 can be engaged with the L-side surface of the upper locking protrusion 94b. The lower end of the cam biasing member 98 is engaged with the L-side surface of the lower locking protrusion 94c or the L-side surface of the lower portion of the second linear portion 96. As a result, the cam biasing member 98 elastically biases the locking cam 94 to maintain a neutral state in which the first linear portion 95 extends in the substantially horizontal, or left-right, direction, as shown in FIG. 20 .

[0056] Furthermore, a cam protrusion 97 is formed on the front surface of the locking cam 94 at the L-side end of the first linear portion 95. When the first linear portion 95 extends in the left-right direction as shown in FIGS. 20 and 21, the lower surface 97a (FIG. 23) of the cam protrusion 97 slopes upward toward the intersection of the first linear portion 95 and the second linear portion 96. On the other hand, when the first linear portion 95 slopes upward in the left-right direction toward its tip as shown in FIG. 19, the lower surface 97a of the cam protrusion 97 is aligned substantially horizontally. The latch protrusion 92 of the latch member 85 can engage with the lower surface 97a of the cam protrusion 97. As a result, when the locking cam 94 rotates in the direction of arrow A1 in FIG. 21 from the state shown in FIG. 21, the R-side end surface 97b of the cam protrusion 97 disengages upward from the L-side surface of the latch protrusion 92. As a result, the latch member 85 moves toward the L side due to the biasing force of the biasing member 93, as shown in FIG. 19. At this time, the latch projection 92 slides on the lower surface 97a of the cam projection 97 and moves to the L side.

[0057] On the other hand, when the latch member 85 is moved to the R side (locking side) by operating the knob portion 90 (FIG. 22) from the state shown in FIG. 19 to lock the storage door lock unit 33, the latch protrusion 92 moves to the R side of the end face 97b, and the locking cam 94 rotates in the direction of arrow A2 in FIG. 19 due to the biasing force of the cam biasing member 98, and the latch protrusion 92 engages with the end face 97b as shown in FIG. 21. In this state, the latch portion 91 of the latch member 85 protrudes from the case 86 to the R side, and the cam protrusion 97 prevents the latch member 85 from returning to the L side, which is the direction in which the latch member 85 retracts into the case 86. In this state, the rotational position of the locking cam 94 returns to the neutral state. Therefore, when the latch portion 91 protrudes to the latch receiving side, the cam protrusion 97 of the locking cam 94 rotates to restrict the returning movement of the knob portion 90 (FIG. 22). In this state, the lower door 16 is locked.

[0058] FIG. 14 illustrates the state in which the lower door 16 is unlocked and the retrieval door 18 is locked while waiting for arrival of luggage. On the other hand, FIG. 24 illustrates the state in which a luggage delivery person has opened the lower door 16. After storing the luggage in the lower storage compartment 23, the luggage delivery person closes the lower door 16 and, as shown in FIG. 25, locks the lower door 16 by moving the knob portion 90 of the storage door lock portion 33 to the R-side position, which is the locked position. In this state, as shown in FIGS. 20 and 21 above, the locking cam 94 engages with the latch protrusion 92 of the latch member 85, so the lower door 16 remains locked.

[0059] Next, when the recipient of the package wants to remove the package from the receiving box 1, as shown in Fig. 26, they unlock the removal door lock unit 34 by operating the unlock button 51 and knob unit 52 shown in Fig. 13, and then open the removal door 18. As a result, as will be described later, the storage door lock unit 33 is unlocked by the operation of the link mechanism 60 provided between the lower door 16 and the removal door 18, allowing the lower door 16 to be opened. Thereafter, the recipient closes the removal door 18, and the removal door lock unit 34 is locked, returning to the arrival waiting state shown in Fig. 14.

[0060] The configuration and operation of the link mechanism 60 will be explained in more detail using Figures 27 to 32. Figure 27 is an enlarged perspective view of part A in Figure 14 when the front and rear doors of the receiving box 1 are locked. Figure 28 is an enlarged perspective view of part C in Figure 27 with the link cover 62 and gear cover omitted. Figure 29 is an enlarged perspective view of the inner surface of the front end portion of Figure 14 when the front and rear doors of the receiving box 1 are locked, viewed from above.

[0061] Link mechanism 60 has a lever receiver 65 and a rear-side link lever 66 shown in Figures 27 and 28, an intermediate link bar 61 shown in Figures 28 and 29, and a front-side release lever 67 shown in Figure 29. Lever receiver 65 is fixed to the R-side end on the inner surface of access door 18. Lever receiver 65 is made of metal or resin and has a generally L-shaped cross section with a fixed plate 65a and a pressure plate 65b that are perpendicular to each other, and the upper ends and lower ends of fixed plate 65a and pressure plate 65b are connected to each other by reinforcing plates 65c, respectively. Fixed plate 65a of lever receiver 65 is fixed to the inner surface of access door 18, and pressure plate 65b extends forward.

[0062] As shown in FIG. 28 , when the access door 18 is closed, the tip of the pressure plate 65b of the lever receiver 65 presses the rear-side link lever 66 forward. The lower end of the rear-side link lever 66 is swingably supported by a gear cover 63 fixed to the link cover 62. The link cover 62 is box-shaped, extending in the front-to-rear direction, with a rectangular cross section and an open R-side end, and is fixed to the inner surface of the right side panel 10c. The gear cover 63 is fixed to the rear end of the link cover 62, and a portion of it protrudes from the L-side surface of the link cover 62. The lower end of the rear-side link lever 66 is supported inside the gear cover 63 so as to be swingable in the front-to-rear direction around a shaft 64 extending in the left-to-right direction. The upper portion of the rear-side link lever 66 protrudes from the upper surface of the gear cover 63, and the rear side of the rear-side link lever 66 can face the tip of the pressure plate 65b of the lever receiver 65.

[0063] A first helical gear 66a is fixed to the R-side surface of the lower end of the rear-side link lever 66, and meshes with a second helical gear 66b fixed to the rear end of the intermediate link bar 61. The intermediate link bar 61 is columnar and extends in the front-to-rear direction, is supported inside the link cover 62, and is rotatable around a central axis in the front-to-rear direction.

[0064] As shown in Figure 29, a front release lever 67 is fixed to the front end of the intermediate link bar 61. The front release lever 67 extends in a direction perpendicular to the front-to-rear direction, which is the extension direction of the intermediate link bar 61. When the access door 18 is in the locked state shown in Figure 29, the tip of the front release lever 67 extends downward in the up-down direction.

[0065] A biasing member 68, which is a coil spring, is wound around the front end of the intermediate link bar 61. Both ends of the biasing member 68 engage with locking projections 69 (see FIG. 32) protruding from the outer circumferential surface of the front end of the intermediate link bar 61 and the inner surface of the link cover 62. The locking projections 69 are formed, for example, by screws that are screwed into the intermediate link bar 61 in a radial direction. As a result, the intermediate link bar 61 is biased by the biasing member 68 in a direction in which the front release lever 67 rotates in the direction of arrow A3 in FIG. 29 and enters the lower opening 86b (FIG. 17) of the case 86 of the storage door locking unit 33. Meanwhile, when the access door 18 is closed as shown in FIGS. 27 to 29, the lever receiver 65 presses the rear link lever 66 toward the lower door 16 against the biasing force of the biasing member 68 so that force from the front release lever 67 is not applied to the storage door locking unit 33. More specifically, in Figure 28, the rear link lever 66 swings forward in the direction of arrow A4, causing the intermediate link bar 61 to rotate in the direction of arrow A5. As a result, in Figure 29, the intermediate link bar 61 rotates in the direction opposite to the direction of arrow A3, and the front release lever 67 faces downward as shown in Figure 29. As a result, the locking cam 94 (Figures 20 and 21) of the storage door lock unit 33 is not pushed in the unlocking direction by the front release lever 67, and the locked state is maintained. In this configuration, the rear link lever 66 is connected to the rear of the intermediate link bar 61 so as to be able to transmit force, and the front release lever 67 is connected to the front of the intermediate link bar 61 so as to be able to transmit force.

[0066] 30 to 32 are views showing the state when a package is being removed from the receiving box, with FIG. 30 corresponding to FIG. 27, FIG. 31 corresponding to FIG. 28, and FIG. 32 corresponding to FIG. 29. When removing a package, the removal door 18 is opened rearward as shown in FIG. 26. In this state, as shown in FIGS. 30 and 31, the lever receiver 65 (FIG. 28) fixed to the removal door 18 moves away from the rear-side link lever 66. As a result, the intermediate link bar 61 is not prevented from rotating in the direction of arrow A6 in FIG. 31 due to the biasing force of the biasing member 68 (FIG. 29). At this time, the rear-side link lever 66 swings in a direction that tilts rearward. Therefore, as shown in FIG. 32, the intermediate link bar 61 rotates in the direction of arrow A7, which is the unlocking direction of the storage door lock unit 33. Therefore, the front release lever 67 enters the lower opening 86b (FIG. 17) of the storage door locking unit 33, and the locking cam 94 (FIGS. 20 and 21) is pushed by the front release lever 67 so as to rotate in the unlocking direction, that is, in the direction of arrow A1 in FIG. 21. At this time, the locking cam 94 is pushed left and right toward the lower door 16. Then, the biasing force of the biasing member 93 of the storage door locking unit 33 causes the latch member 85 to retract toward the lower door 16, unlocking the storage door locking unit 33 and allowing the lower door 16 to open. In this way, due to the operation of the link mechanism 60, the storage door locking unit 33 is unlocked when the access door 18 is opened.

[0067] From this state, the recipient of the package takes out the package, closes the take-out door 18 again, and locks the take-out door locking section 34, and the package receiving box 1 returns to the package arrival standby state.

[0068] The above has described in detail the structure in which link mechanism 60 is provided in lower storage chamber 23 between removal door 18 and lower door 16, but as shown in Fig. 8, link mechanism 99 is also provided in upper storage chamber 22 between removal door 18 and upper door 14, and the configuration of link mechanism 99 is the same as link mechanism 60. Link mechanism 99 is an upper link mechanism, and link mechanism 60 is a lower link mechanism.

[0069] 3, the storage door locking units 32, 33 provided on the receiving box 1 include the upper storage door locking unit 32 capable of locking the upper door 14 and the lower storage door locking unit 33 capable of locking the lower door 16. The receiving box 1 is configured so that the upper storage door locking unit 32 and the lower storage door locking unit 33 are unlocked via the link mechanisms 99 and 60, respectively, when the retrieval door 18 is opened. This allows the recipient of a package to simultaneously unlock the upper storage door locking unit 32 and the lower storage door locking unit 33 and open the upper door 14 and the lower door 16 simply by unlocking and opening the retrieval door 18 to retrieve the package from the receiving box 1. In this way, the locking units of the upper door 14 and the lower door 16 can be unlocked by simply opening one retrieval door 18, further simplifying the recipient's unlocking operation.

[0070] The above-described receiving box 1 functions as both a mailbox and a parcel box, and includes a mail storage compartment 20, a parcel storage compartment 21, and storage door locks 32, 33 that can lock the upper door 14 or lower door 16 that closes the front of the parcel storage compartment 21. The receiving box 1 is also configured so that the storage door lock 33 is unlocked when the access door 18 is opened, thanks to link mechanisms 99, 60 provided between the access door 18 and the storage door locks 32, 33. This reduces the number of components and simplifies installation, unlike when the mailbox and parcel box are provided as separate components. Furthermore, the recipient can simply open the access door 18 to move to the front of the upper door 14 or lower door 16 and unlock the corresponding storage door locks 32, 33 without having to unlock them with a key or other device. This simplifies the recipient's unlocking process.

[0071] Additionally, the movable shelf 25 is supported by the box body 10 in a state in which it can pivot about a pin 42 provided on the hanging side. This allows the movable shelf 25 to be pivoted downward to form a single large parcel storage compartment that is not divided into the upper storage compartment 22 and the lower storage compartment 23. This makes it possible for the receiving box 1 to receive large parcels that cannot fit into the upper and lower storage compartments 22, 23.

[0072] Additionally, an upper door 14 and a lower door 16 are provided in front of each storage compartment 22, 23, and each door is provided with a lockable storage door lock 32, 33. This allows parcels to be received at different times in the upper storage compartment 22 and the lower storage compartment 23, even when the receiving box 1 is used for a detached house, thereby improving the convenience of the recipient. Furthermore, when receiving parcels or mail in each storage compartment 22, 23, the parcels and mail can be received by simply opening one access door 18, thereby further improving the convenience of the recipient. In this example, one or more intermediate storage compartments separated by shelves such as movable shelves may be provided between the upper storage compartment 22 and the lower storage compartment 23, and an intermediate door with a lockable storage door lock may be provided in front of the intermediate storage compartment in an openable / closable manner, and a link mechanism similar to the link mechanism 60 may be provided between the access door and the intermediate door.

[0073] Additionally, the movable shelf 25 supports a handle member 35 having a handle 37 linked to an engaging portion 36, and the engaging portion 36 protruding from the side of the movable shelf 25 engages with a receiving portion 41 provided on the inside of the box body 10, thereby fixing the movable shelf 25. This allows the user to easily disengage the engaging portion 36 from the receiving portion 41 by moving the handle 37, and easily change the size of the delivery storage compartment.

[0074] FIG. 33 is a view corresponding to FIG. 11 and shows a movable shelf 25f in another example of the embodiment. In this example, a sensor pressing portion 105 and a switch-type open / close sensor 106 serving as a detection portion are provided at the R-side end of the movable shelf 25f, aligned in the front-rear direction with the engaging portion 36 of the handle member 35. The sensor pressing portion 105, like the handle member 35, is supported on the movable shelf 25f so as to be movable in the left-right direction. For this reason, a support portion (not shown) that supports the sensor pressing portion 105 so as to be movable in the left-right direction is fixed to the movable shelf 25f. An opening 25g is formed on the R-side surface of the movable shelf 25f through which the sensor pressing portion 105 can protrude. The sensor pressing portion 105 is biased in the direction of protruding from the R-side surface of the movable shelf 25f by a biasing member such as a spring supported by the support portion.

[0075] When the sensor pressing portion 105 is pushed back against the biasing force of the biasing member, the open / close sensor 106 detects that the sensor pressing portion 105 has been pushed back. For example, the open / close sensor 106 outputs an ON signal indicating that the sensor pressing portion 105 has been pushed back.

[0076] With this configuration, when the movable shelf 25f is in a horizontal position and the sensor pressing portion 105 abuts against the side surface of the right side panel 10c or the support member 40 (see FIG. 12) fixed to the right side panel 10c and is pushed back toward the inside of the movable shelf 25f, the open / close sensor 106 outputs an ON signal. On the other hand, when the abutment state between the engagement portion 36 provided on the movable shelf 25f and the right side panel 10c or the support member 40 is released and the movable shelf 25f is tilted downward along the left side panel 10b, the sensor pressing portion 105 protrudes outward from the movable shelf 25f due to the biasing force of the biasing member. In this case, the open / close sensor 106 does not detect that the sensor pressing portion 105 has been pushed back, and therefore is turned OFF.

[0077] The open / close sensor 106 is connected by a signal line or the like to an operation panel having a control device attached to, for example, the box body 10 or the outer door 12. In this case, the operation panel may have a display unit such as a liquid crystal display unit and an operation unit, and the upper door 14 and the lower door 16 may be unlocked by operating the operation unit and entering a PIN number. The display unit may also be configured to display the parcel storage compartments available for delivery. When the open / close sensor 106 is OFF, the display unit may be configured to display that the upper and lower storage compartments are not separated and only one large storage compartment can be selected. This prevents erroneous operation in which only one of the upper and lower storage compartments is selected when only one large storage compartment is available.

[0078] On the other hand, it is preferable that the operation panel be configured so that when an ON signal is input from the open / close sensor 106, only one of the upper and lower storage compartments can be selected.

[0079] In the above examples, upper door 14 and lower door 16 are provided in front of the delivery storage compartment, but the delivery storage compartment may be configured so that it is not divided internally by shelves, but has a single storage door in front of it, and is provided with a storage door lock that can be locked. In this case, too, a link mechanism provided between removal door 18 and the storage door lock can be used to unlock the storage door lock when removal door 18 is opened.

[0080] In each of the above examples, the storage door locking units 32, 33 can be configured to be installed upside down, so that they can be adapted to accommodate storage doors that are installed on opposite sides.

[0081] In the above examples, the case where the removal door 18 is provided with a removal door lock unit 34 that can be unlocked by a PIN code has been described. However, the removal door 18 may also be configured to have a door lock unit that can be unlocked by inputting a PIN code or the like using a battery built into the receiving box 1 or power from an external commercial power source.
